[0002] Plastic extruders are essential equipment for manufacturing plastic products. They use power transmission and heating elements to transport, compact, and melt plastic to form its shape. During prolonged use, plastic residue can easily accumulate on the surface of the extrusion rod, affecting the extrusion efficiency of the plastic extruder. Regular cleaning is required.

[0003] Existing plastic extruder rod cleaning methods involve removing the extruder rod from the extruder and then removing the plastic residue stuck to it by burning or heating it. This is time-consuming and labor-intensive, and can easily damage the metal properties of the extruder rod, causing it to bend and affecting its mechanical tolerances. Therefore, this application proposes a residue cleaning mechanism for plastic extruders to solve the above problems. Utility Model Content

The main body mechanism includes a box body, protective doors symmetrically arranged and hinged to the box body, first round rods symmetrically fixed to the inner walls of the box body, a movable bracket slidably sleeved on the first round rod, a driving component installed on the inner walls of the box body and passing through the movable bracket, a nozzle fixed to the bottom of the movable bracket, a high-pressure pump installed on the outer side of the box body with one end connected to the nozzle and the other end connected to the bottom of the inner cavity of the box body, and a collection frame movably fitted into the inner cavity of the box body.

[0006] The fixing mechanism includes a second round rod symmetrically fixed to the inner wall of the box, a U-shaped frame symmetrically fixed to both sides of the second round rod, placement wheels symmetrically fixed to the U-shaped frame, a clamping member movably installed at the top of the U-shaped frame, and a second motor fixed to the clamping member on one side.

[0007] In a preferred embodiment, the present invention can be further configured such that the movable bracket includes a movable seat slidably sleeved on a relative first round rod and hanging rods symmetrically fixed to the bottom end of the movable seat.

[0008] In a preferred embodiment, the present invention can be further configured such that: the driving component includes a threaded rod rotatably mounted on the inner wall of the housing and a first motor fixed on the outer side of the housing with its shaft fixedly connected to the end of the threaded rod; the movable seat has a threaded hole in the middle, the threaded rod passes through the threaded hole, and the threaded rod and the threaded hole mesh with each other.

[0009] In a preferred embodiment, the present invention can be further configured such that: the inlet of the high-pressure pump is connected to the bottom of the inner cavity of the box through an inlet pipe, and the outlet of the high-pressure pump is connected to the nozzle through an outlet pipe.

[0010] In a preferred embodiment, the present invention can be further configured such that: rectangular plates are fixed on the opposite inner walls of the box, and the collection frame includes a frame that is slidably fitted into the inner cavity of the box and located above the rectangular plates, and a filter screen fixed on the inner wall of the frame.

[0011] In a preferred embodiment, the present invention can be further configured such that the clamping member includes a plurality of support rods that move through the top of the U-shaped frame, a bracket fixed to the bottom of the support rods, rollers rotatably mounted on the bracket, and an electric telescopic rod fixed to the top of the U-shaped frame and whose end is fixedly connected to the bracket.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0018] Some embodiments of this utility model are described below with reference to the accompanying drawings. Example

[0019] Combination Figure 1-5 As shown, this embodiment provides a residue cleaning mechanism for a plastic extruder, including: a main body mechanism 100 and a fixing mechanism 200.

[0020] The main structure 100 includes a housing 110, a protective door 120 symmetrically arranged and hinged to the housing 110, a first round rod 130 symmetrically fixed to the inner walls of the housing 110, a movable bracket 140 slidably sleeved on the first round rod 130, a drive component 150 installed on the inner walls of the housing 110 and passing through the movable bracket 140, a nozzle 160 fixed to the bottom of the movable bracket 140, a high-pressure pump 170 installed on the outer surface of the housing 110 with one end connected to the nozzle 160 and the other end connected to the bottom of the inner cavity of the housing 110, and a collection frame 180 movably fitted into the inner cavity of the housing 110.

[0021] The housing 110 is used to form a closed environment to facilitate cleaning of the extrusion rod. The protective door 120 is used to open or close the housing 110 to facilitate the insertion and removal of the extrusion rod, while preventing water from splashing out during the cleaning of the extrusion rod.

[0022] The first round rod 130 is used to install the movable bracket 140. The movable bracket 140 includes a movable seat 141 that is slidably sleeved on the first round rod 130 and a hanging rod 142 that is symmetrically fixed to the bottom of the movable seat 141. Round holes are opened on both sides of the movable seat 141. The first round rod 130 passes through the round holes, so that the movable seat 141 can slide stably on the first round rod 130. The hanging rod 142 is used to install the nozzle 160, ensuring the stability of the nozzle 160, and at the same time, it can drive the nozzle 160 to move synchronously when the movable seat 141 moves.

[0023] The drive frame is used to drive the movable bracket 140 to move. It includes a threaded rod 151 rotatably mounted on the inner wall of the housing 110 and a first motor 162 fixed on the outer surface of the housing 110 with its shaft fixedly connected to the end of the threaded rod 151. The movable seat 141 has a threaded hole 1411 in the middle. The threaded rod 151 passes through the threaded hole 1411 and the threaded rod 151 meshes with the threaded hole 1411. When the first motor 162 is started, it drives the threaded rod 151 to rotate. The threaded rod 151 rotates in the threaded hole 1411, which drives the movable seat 141 to move. In turn, the hanging rod 142 drives the nozzle 160 to move, which facilitates cleaning different positions of the extrusion rod.

[0024] The nozzle 160 is used to spray high-pressure water to wash away plastic residues attached to the extrusion rod. The inlet of the high-pressure pump 170 is connected to the bottom of the inner cavity of the housing 110 through the inlet pipe 171, and the outlet of the high-pressure pump 170 is connected to the nozzle 160 through the outlet pipe 172. This allows water to be pressurized and sent into the nozzle 160 to increase the flushing force of the water flow. In addition, a rectangular hole is opened on the side of the housing 110 opposite to the protective door 120. The outlet pipe 172 is a flexible hose that passes through the rectangular hole and extends into the housing 110 to connect with the nozzle 160, ensuring that the outlet pipe 172 can move synchronously with the nozzle 160 when the nozzle 160 moves.

[0025] Rectangular plates 111 are fixed on the inner walls of the box 110. The collection frame 180 includes a frame 181 that is slidably fitted into the inner cavity of the box 110 and located above the rectangular plates 111, and a filter screen 182 fixed on the inner wall of the frame 181. The frame 181 is used to install the filter screen 182, and the filter screen 182 is used to filter plastic residue in the water flow, so that the plastic residue accumulates in the frame 181 for subsequent processing.

[0026] The fixing mechanism 200 is used to position the extrusion rod and drive the extrusion rod to rotate. It includes a second round rod 210 symmetrically fixed on the inner wall of the housing 110, a U-shaped frame 220 symmetrically fixed on both sides of the second round rod 210, a placement wheel 230 symmetrically fixed on the U-shaped frame 220, a clamping member 240 movably installed on the top of the U-shaped frame 220, and a second motor 250 fixed on one side of the clamping member 240.

[0027] The second round rod 210 is used to fix the U-shaped frame 220. The U-shaped frame 220 is used to install other components. The placement wheels 230 are symmetrically arranged to place the end of the extrusion rod and facilitate the subsequent rotation of the extrusion rod.

[0028] The clamping component 240 includes multiple support rods 241 that move through the top of the U-shaped frame 220, a bracket 242 fixed to the bottom of the support rods 241, rollers 243 rotatably mounted on the brackets 242, and an electric telescopic rod 244 fixed to the top of the U-shaped frame 220 and whose end is fixedly connected to the brackets 242. When the electric telescopic rod 244 is activated, it drives the brackets 242 to move down. The downward movement of the brackets 242 drives the rollers 243 to move down. The downward movement of the rollers 243 presses the end of the extrusion rod against the placement wheel 230 to ensure the stability of the extrusion rod. At the same time, the shaft of the second motor 250 is fixedly connected to the end of the rollers 243 to drive the rollers 243 to rotate. The rotation of the rollers 243 drives the extrusion rod to rotate, which facilitates the high-pressure water flow to clean the extrusion rod from all directions.

[0029] The working principle and usage process of this utility model are as follows: During use, both ends of the extrusion rod are placed on the placement wheels 230 on the U-shaped frames 220 on both sides. At this time, the electric telescopic rod 244 is activated, driving the support 242 to move downwards. The downward movement of the support 242 drives the roller 243, which in turn presses the ends of the extrusion rod firmly onto the placement wheels 230. Simultaneously, the second motor 250 is activated, driving the roller 243 to rotate. The rotation of the roller 243 drives the extrusion rod to rotate. At this time, the high-pressure water pump is activated, pumping clean water through the outlet pipe 172 into the nozzle 160. The high-pressure water flows downwards through the nozzle 160. The water jet cleans the plastic residue adhering to the surface of the extrusion rod. Simultaneously, the first motor 162 starts, driving the threaded rod 151 to rotate. The rotation of the threaded rod 151 drives the movable bracket 140 to move, which in turn moves the nozzle 160 to facilitate cleaning of the entire extrusion rod. The plastic residue washed out by the high-pressure water jet falls into the collection frame 180 with the water flow. The plastic residue is filtered by the filter screen 182 and accumulates in the frame 181. The water flows through the filter screen 182 and falls into the bottom of the inner cavity of the box 110, and is then drawn out again by the high-pressure water pump through the water inlet pipe 171, forming a cycle.

[0030] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
