Description

Technical Field

[0001] The utility model relates to the technical field of feeding devices, in particular to a proportioning box feeding component with a debris removal structure. Background Art

[0002] Today, thermoplastic plastic product processing is also called plastic forming processing. It is a general term for various processes that convert synthetic resins or plastics into plastic products. Plastic processing generally includes plastic batching, molding, machining, joining, modification and assembly. The feeding devices on the market are generally used to directly provide a proportioning box for pre-placement. The raw materials will be mixed with some impurities more or less during the feeding process or the production process.

[0003] At present, when loading materials into the proportioning box, in order to filter these impurities, a filter is usually directly installed inside the proportioning box to filter the plastic and block impurities that do not meet the size, so as to facilitate subsequent use.

[0004] However, the filtration structure has poor practicality when in use. Although the filtration structure of the device filters through the filter, the filtered impurities will still dock on the surface of the filter, which leads to poor practicality during the subsequent continuous feeding process, thereby affecting the overall feeding efficiency. In view of this, we propose a proportioning box feeding component with an impurity removal structure. Utility Model Content

[0005] The utility model aims to provide a proportioning box feeding assembly with a debris removal structure to solve the problems raised in the above-mentioned background technology.

[0007] Preferably, the knocking structure includes a directional cylinder fixedly installed on both sides of the inner wall of the mixing box, an extrusion rod is slidably connected inside the directional cylinder, a pressure plate is fixedly installed on the side wall of the extrusion rod, and T-shaped knocking blocks are slidably connected on both sides of the inner wall of the mixing box, one end of the connecting rod is hinged on the side wall of the T-shaped knocking block, and the other end of the connecting rod is hinged to the lower end of the pressure plate, and a return spring is arranged on the surface of the extrusion rod.

[0011] Preferably, the moving track of the moving cylinder is highly matched to the sieve plate.

[0012] Compared with the prior art, the utility model provides a proportioning box feeding assembly with a debris removal structure, which has the following beneficial effects:

[0013] 1. The proportioning box feeding assembly with impurity removal structure is provided with an impurity removal structure to facilitate the cleaning of impurities accumulated on the surface of the filter screen. The user can drive the reciprocating screw to rotate by rotating the motor, so that the sleeve drives the sieve plate to move back and forth to push out the impurities for cleaning.

[0014] 2. The feeding assembly of the proportioning box with a de-impurity structure is provided with a knocking structure to facilitate the knocking of the filter, thereby avoiding clogging in the mesh of the filter and affecting its use. Every time the sleeve moves back and forth, the side wall of the sleeve will squeeze the pressure plate once, and the pressure plate moves outward to drive the connecting rod at its lower end to move. The movement of the connecting rod drives the T-shaped knocking block to move downward to knock and vibrate the surface of the filter, thereby avoiding plastic particles sticking to the mesh of the filter and causing clogging to affect its use.

The impurity removal structure 3 includes a reciprocating screw rod 31 rotatably connected to the inner wall of the proportioning box 1 through a shaft sleeve, a motor 32 is fixedly installed on the side wall of the proportioning box 1, and the output shaft of the motor 32 passes through the inner wall of the proportioning box 1 and is fixedly connected to the end of the reciprocating screw rod 31. A sleeve 33 is slidably connected to the surface of the reciprocating screw rod 31, and a driving member 34 is fixedly installed on the lower end of the sleeve 33. The driving member 34 is driven by the reciprocating screw rod 31. A slanted groove column 35 is fixedly installed at the lower end of the moving part 34, and a bearing 36 is rotatably connected to the lower end of the slanted groove column 35. A sieve plate 37 is fixedly installed at the lower end of the bearing 36. A moving cylinder 38 is rotatably connected to the surface of the slanted groove column 35. One end of an L-shaped rod 39 is fixedly installed on both sides of the moving cylinder 38, and a cleaning plate 310 is fixedly installed on the other end of the L-shaped rod 39. Impurity outlets 311 are opened on both sides of the inner wall of the proportioning box 1. A knocking structure 4 is arranged inside the proportioning box 1. The cleaning plate 310 is in contact with the surface of the sieve plate 37. Collecting boxes 8 are fixedly installed on both sides of the proportioning box 1. The moving trajectory of the moving cylinder 38 is adapted to the height of the sieve plate 37.

[0021] Specifically, the impurity removal structure 3 of the technical solution of the utility model includes: a reciprocating screw 31, a motor 32, a sleeve 33, a driving member 34, a chute column 35, a bearing 36, a sieve plate 37, a moving cylinder 38, an L-shaped rod 39, a cleaning plate 310, and an impurity outlet 311.

[0022] In one embodiment of the utility model, a cleaning structure 3 is provided to facilitate cleaning of impurities accumulated on the surface of the filter screen 5. When in use, the user puts the plastic raw material through the feed port 2, and then uses the filter screen 5 inside the proportioning box 1 to filter the plastic to block impurities that do not meet the size. When the impurities on the surface of the filter screen 5 accumulate to a certain extent, the user can start the motor 32 to work, and the rotation of the motor 32 drives the reciprocating screw 31 on its surface to rotate. The rotation of the reciprocating screw 31 causes the sleeve 33 on its surface to move back and forth. The movement of the sleeve 33 indirectly drives the sieve plate 37 to move back and forth to push out the impurities for cleaning. A sieve plate 37 is provided to push and clean impurities, and the sieve holes allow normal plastic to move, thereby avoiding the problem of both raw materials and impurities falling off when a scraper without sieve holes is used for cleaning. At the same time, the user can start the driving member 34 to drive the inclined slot column 35 to rotate. The rotation of the inclined slot column 35 drives the moving cylinder 38 on its surface to move up and down. The movement of the moving cylinder 38 drives the L-shaped rod 39 and the cleaning plate 310 on its side wall to move. The cleaning plate 310 cleans back and forth on the surface of the sieve plate 37, thereby avoiding adhesion and accumulation on the surface of the sieve plate 37, thereby further improving the practicality of the device.

[0023] Please continue reading Figure 1-Figure 4 The knocking structure 4 includes a directional cylinder 41 fixedly installed on both sides of the inner wall of the proportioning box 1, an extrusion rod 42 is slidably connected inside the directional cylinder 41, and a pressure plate 43 is fixedly installed on the side wall of the extrusion rod 42. T-shaped knocking blocks 44 are slidably connected on both sides of the inner wall of the proportioning box 1. One end of a connecting rod 45 is hinged on the side wall of the T-shaped knocking block 44, and the other end of the connecting rod 45 is hinged to the lower end of the pressure plate 43. A return spring 46 is arranged on the surface of the extrusion rod 42, and one end of the return spring 46 is fixedly connected to the side wall of the directional cylinder 41, and the other end of the return spring 46 is fixedly connected to the side wall of the pressure plate 43. By setting the knocking structure 4 Thereby, it is convenient to knock the filter 5, so as to avoid clogging in the mesh of the filter 5 and affecting its use. Every time the sleeve 33 moves back and forth, the side wall of the sleeve 33 will contact and squeeze the pressure plate 43 once. At this time, the pressure plate 43 moves outward and compresses the return spring 46, and the movement of the pressure plate 43 will drive the connecting rod 45 to move. The movement of the connecting rod 45 drives the T-shaped knocking block 44 hinged thereto to move downward, and the T-shaped knocking block 44 moves downward to knock and vibrate the surface of the filter 5, so as to avoid plastic particles sticking to the mesh of the filter 5 and causing clogging and affecting its use.

[0024] During operation, the plastic raw material can be first put in through the feed port 2, and then the plastic can be filtered through the filter screen 5. When the impurities on the surface of the filter screen 5 accumulate to a certain extent, the motor 32 is started to work, and the motor 32 rotates to drive the reciprocating screw 31 on its surface to rotate. The reciprocating screw 31 rotates so that the sleeve 33 on its surface moves back and forth. The movement of the sleeve 33 indirectly drives the sieve plate 37 to move back and forth to push out the impurities for cleaning. At the same time, the driving member 34 can be started to drive the inclined slot column 35 to rotate. The rotation of the inclined slot column 35 drives the moving cylinder 38 on its surface to move up and down. The movement of the moving cylinder 38 drives the L-shaped rod 39 and the cleaning plate 310 of its side wall to move. The cleaning plate 310 cleans the surface of the sieve plate 37 back and forth, thereby avoiding adhesion and accumulation on the surface of the sieve plate 37. Every time the sleeve 33 moves back and forth, the side wall of the sleeve 33 contacts and squeezes the pressure plate 43 once. At this time, the pressure plate 43 moves outward and compresses the reset spring 46, and the movement of the pressure plate 43 drives the connecting rod 45 to move. The movement of the connecting rod 45 drives the T-shaped knocking block 44 hinged thereto to move downward. The T-shaped knocking block 44 moves downward to knock and vibrate the surface of the filter screen 5, thereby avoiding plastic particles sticking to the mesh of the filter screen 5 and causing blockage to affect use, thereby improving the practicability of the device and further improving the impurity removal effect of the device.
