[0001] The present utility model relates to the field of plastic granulation equipment, in particular to a loss-in-weight Gravimetric blender discharge port bushing.
【Background technique】
[0002] The loss-in-weight Gravimetric blender discharge port bushing is used between the outer sleeve of the feeding screw and the T-shaped sleeve to reduce the friction and wear between the outer sleeve of the screw and the T-shaped sleeve, as well as a certain sealing effect. The shaft sleeve is cylindrical, the inner diameter is matched with the outer sleeve of the screw, and the outer diameter is matched with the T-shaped sleeve.
[0003] During production, the Gravimetric blender will be used to feed pellets and powder. If it encounters a powder with good fluidity, the powder will "flow out" autonomously during the production process, especially when refilling, causing inaccurate measurement.
[Utility model content]
[0004] The purpose of the present utility model is to provide a loss-in-weight Gravimetric blender outlet bushing that can restrict flow.
[0005] In order to solve the above-mentioned technical problems, the utility model of the loss-in-weight Gravimetric blender discharge port bushing includes: a T-shaped sleeve; a sleeve, one end of the sleeve is connected to the T-shaped sleeve; a screw jacket The outer sleeve of the screw is connected to the other end of the sleeve; wherein the sleeve includes: a sleeve shaft, the sleeve shaft is a hollow cylindrical shape, and an internal thread is provided on the inner wall of the sleeve shaft; A restrictor, on the first restrictor is provided with a first restrictor hole; on the outer edge of the first restrictor is provided with an external thread; a second restrictor, on the second restrictor A second restrictor hole is provided on the sheet; an external thread is provided on the outer edge of the second restrictor sheet; wherein the first restrictor sheet and the second restrictor sheet are attached to each other; the outer thread and The internal threads are matched.
[0006] Baffle rings are provided at both ends of the sleeve shaft.
[0007] The first restrictor plate and the second restrictor plate are circular, and the first restrictor plate and the second restrictor plate pass through the external thread and the internal thread and the Sleeve connection.
[0008] The lower material port bushing of the weightless Gravimetric blender of the present invention is provided with a first restrictor and a second restrictor that are coaxially arranged through a thread in the sleeve shaft, the first restrictor and the second restrictor The flow fins can be relatively rotated. Since the first and second flow restriction holes are respectively opened on the first and second flow restriction sheets, the rotation of the first flow restriction sheet and the second flow restriction sheet can be changed. The size of the flow hole formed by the first flow restriction hole and the second flow restriction hole is used to limit the flow. In addition, the bottom of the sleeve shaft is provided with a baffle ring, which can prevent the first and second current limiting plates from falling off.
The utility model of the loss-in-weight Gravimetric blender discharge port bushing is described in further detail.
[0018], the present utility model loss-in-weight Gravimetric blender discharge port shaft sleeve, including: T-shaped sleeve 1, sleeve 2 and screw outer tube 9 connected to each other.
[0019] Wherein the sleeve 2 includes: a hollow cylindrical sleeve shaft 3, in the sleeve shaft 3 is provided with a coaxial threaded first restrictor 4 and a second restrictor 6, the first restrictor The sheet 4 and the second restrictor sheet 6 can rotate relatively, because the first restrictor hole 5 and the second restrictor hole 7 are respectively opened on the first restrictor sheet 4 and the second restrictor sheet 6, which pass through the first restrictor sheet. The rotation of the flow sheet 4 and the second flow restriction sheet 6 can change the size of the flow hole formed by the first flow restriction hole 5 and the second flow restriction hole 7 to achieve a flow restriction function.
[0020] In addition, at both ends of the bottom of the sleeve shaft 3 are provided with baffle rings 8, which can prevent the first restrictor 4 and the second restrictor 6 from falling off.
[0021] The lower material port shaft sleeve of the weightless Gravimetric blender of the present invention is provided with a first restrictor plate and a second restrictor plate coaxially arranged through a thread in the sleeve shaft, the first restrictor plate and the second restrictor The flow fins can be relatively rotated. Since the first and second flow restriction holes are respectively opened on the first and second flow restriction sheets, the rotation of the first flow restriction sheet and the second flow restriction sheet can be changed. The size of the flow hole formed by the first flow restriction hole and the second flow restriction hole is used to limit the flow. In addition, the bottom is provided with a baffle ring, which can prevent the first and second current-limiting plates from falling off.
[0022] The preferred embodiments of the invention have been described in detail above, but the invention of the invention is not limited to the embodiments, and those skilled in the art can also do so without departing from the spirit of the invention. Various equivalent modifications or substitutions are made, and these equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
