Technical Field

[0001] The utility model belongs to the technical field of extruded board production, in particular to an extrusion die for an extruded board. Background Art

[0002] Extruded board is a commonly used building material, mainly made of polystyrene resin. Its manufacturing process involves heating polystyrene particles to a high temperature to make them soft and easy to process, and then squeezing them into a board shape through a special extrusion machine.

[0003] For example, the Chinese patent with the publication number CN215791609U discloses an extrusion die for the production of plastic co-extruded wallboards, which includes an extruder with an extrusion die, and the extruder is connected to two guide plates symmetrical to the extrusion die at a position close to the discharge port of the extrusion die, and the two guide plates are provided with guide grooves parallel to the extrusion die on one side close to each other, and a metal sleeve is slidably connected between the two guide grooves, and the metal sleeve is provided with a friction groove adapted to the discharge port of the extrusion die, and the extruder is provided with a moving mechanism for driving the metal sleeve to slide along the guide groove. The utility model is provided with a moving mechanism on the extruder, and under the action of the moving mechanism, the metal sleeve can be driven to slide back and forth along the guide groove, so that the friction groove on the metal sleeve can rub the extruded PVC co-extruded board back and forth, thereby removing burrs and miscellaneous edges on the PVC co-extruded board.

[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when used, such as: the above device can only remove burrs and edges of extruded plates of one specification, and cannot remove burrs of extruded plates of different specifications, resulting in a low application range of the overall device. At the same time, after the above device removes burrs, debris will fall on the device, polluting the environment. In view of this, we propose an extrusion die for extruded plates. Utility Model Content

[0006] The utility model aims to provide an extrusion die for an extruded plate to solve the problems raised in the above background technology.

[0007] In view of this, the utility model provides an extrusion die for an extruded plate, comprising:

[0008] An extrusion device body, wherein two sliding grooves are provided on the top of the extrusion device body, a sliding block is slidably installed in the sliding groove, and a sliding plate is fixedly installed on the top of the sliding block through the corresponding sliding groove and extends to the outside;

[0010] A cleaning plate, the cleaning plate is fixedly installed between the two sliding plates, and the bottom of the cleaning plate is tightly fitted with the top of the extrusion device body, and a metal sleeve is inserted and installed between the two sliding plates and above the cleaning plate;

[0011] A fixing assembly, which is located on the two sliding plates and is used to fix the position of the metal sleeve;

[0012] The collecting tank is provided in the extrusion device body, and the top of the collecting tank is connected to the outside. When a sealing plate is installed at the discharge port of the collecting tank for replacement, the metal sleeve can be taken out through the provided fixing assembly, and then a new metal sleeve can be inserted between the two sliding plates. The position of the metal sleeve is fixed through the provided fixing assembly, so that the metal sleeve can be easily replaced;

[0013] When the extruded plate needs to be deburred, one of the sliding plates can be driven to slide through the set driving assembly, and one of the sliding plates drives the other sliding plate to slide through the metal sleeve, and the four guide rods are set to make the two sliding plates more stable when sliding, and then the metal sleeve can slide to deburr the extruded plate, and the two sliding plates slide and drive the cleaning plate to slide at the same time, and the cleaning plate can clean the debris generated by the extruded plate and push the debris into the collecting trough. At the same time, the debris on the top surface of the cleaning plate will slide downward, and when the debris in the collecting trough needs to be collected, the sealing plate is first pulled to clean the debris in the collecting trough, and finally the sealing plate is inserted into the collecting trough to ensure that the position of the sealing plate does not change.

[0014] In the above technical solution, further, the driving component includes:

[0016] In the present technical scheme, when it is necessary to deburr the extruded plate, the servo motor is first started. The servo motor is powered on and drives the threaded rod to rotate. Under the action of the thread, the threaded rod drives one of the sliding plates to slide, and one of the sliding plates drives the other sliding plate to slide through the metal sleeve. The four guide rods are set up to make the two sliding plates more stable when sliding. Then the metal sleeve can slide and deburr the extruded plate. The sliding of the two sliding plates drives the cleaning plate to slide at the same time. At this time, the cleaning plate can clean the debris generated by the extruded plate and push the debris into the collection tank. At the same time, the debris on the top surface of the cleaning plate will slide downward.

[0017] In the above technical solution, further, the fixing assembly includes:

[0018] Two limit grooves, the two limit grooves are respectively opened in the two sliding plates, and the limit grooves are located above the metal sleeve, a sliding bar is slidably installed in the limit groove, the sliding bar is located at the top of the metal sleeve, and the bottom of the sliding bar contacts the top of the metal sleeve, and a spring fixed to the inner wall of the limit groove is fixedly installed at one end of the sliding bar away from the metal sleeve, and the tops of the two sliding bars respectively penetrate the two sliding plates and extend to the outside and are fixedly installed with the same connecting rod.

[0019] In the present technical solution, when the metal sleeve needs to be replaced, first pull the connecting rod and drive the two sliding bars to slide, and at the same time the two springs are squeezed and contracted. When the two sliding bars slide to the appropriate position, the metal sleeve can be taken out, and then a new metal sleeve can be inserted between the two sliding plates. Then the connecting rod is released, and under the action of the rebound force of the two springs, the spring pushes the two sliding bars and the connecting rod to slide. When the sliding bar slides to the appropriate position, the position of the metal sleeve is fixed, thereby facilitating the replacement of the metal sleeve.

At this time, the debris in the collecting tank is cleaned, and finally the sealing plate is inserted into the collecting tank. Then the two magnets 1 are magnetically connected to the two magnets 2 respectively to ensure that the position of the sealing plate does not change.

[0022] In the above technical solution, further, the bottom of the collecting trough is arranged to be inclined, and two guide rods fixed to the extrusion device body are slidably installed in the two sliding plates.

The position of the metal sleeve is fixed by the set fixing component, so that the metal sleeve can be easily replaced.

[0028] 2. The extrusion die of the extruded board can drive one of the sliding plates to slide through the set driving assembly, and one of the sliding plates drives the other sliding plate to slide through the metal sleeve. The sliding of the two sliding plates drives the cleaning plate to slide at the same time. At this time, the cleaning plate can clean the debris generated by the extruded board and push the debris into the collecting groove. At the same time, the debris on the top surface of the cleaning plate will slide downward. When the debris in the collecting groove needs to be collected, the sealing plate is first pulled to clean the debris in the collecting groove.
