Description

Technical Field

[0001] This utility model relates to the field of production and processing, and in particular to a waste treatment device for the production of PVC flame-retardant sleeves. Background Technology

[0002] PVC flame-retardant conduit is a protective tube made of PVC material with added flame retardants. It has good elasticity, wear resistance, corrosion resistance, oxidation resistance, insulation, and excellent flame-retardant properties. It can effectively prevent combustion and avoid the spread of flames. It is often used to protect wires and cables to prevent short circuits or overload fires from igniting flammable materials around the circuit.

[0003] Currently, the production process of existing PVC flame-retardant sleeves often generates waste. However, since PVC flame-retardant sleeves are often made from PVC as the raw material, and after processing, they can be reshaped and put into use, manufacturers often recycle the waste generated during the production of PVC flame-retardant sleeves in order to save material costs.

[0004] To facilitate the heating and melting of PVC flame-retardant sleeve waste and save on storage space, it is often necessary to crush the waste before recycling. However, during the crushing process, some waste enters the crushing area poorly, resulting in ineffective crushing. Furthermore, when the PVC waste particles are large, reheating and melting them often takes more time, thus affecting the reuse of the waste. Therefore, a waste processing device for the production of PVC flame-retardant sleeves is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a waste treatment device for the production of PVC flame-retardant sleeves, which aims to improve the problem in the prior art that some large particles are easily generated when crushing PVC flame-retardant sleeve waste, affecting reprocessing.

[0007] As a further description of the above technical solution:

[0008] The crushing assembly includes a motor, which is fixedly connected to the rear end of the housing. An installation chamber is provided on the inner wall of the housing. The output shaft of the motor passes through the inner wall of the housing located on the rear side of the installation chamber. A gear one is fixedly connected to the output shaft of the motor. A gear two is rotatably connected to the inner wall of the installation chamber. A crushing roller is fixedly connected to the front end of the gear one.

[0009] As a further description of the above technical solution:

[0010] The shaft of the crushing roller passes through the inner wall between the operating chamber and the installation chamber. The number of crushing rollers is set to two, and the shaft of the other crushing roller is fixedly connected to the front end of the second gear.

[0011] As a further description of the above technical solution:

[0012] The feeding assembly includes a rotating rod, which is connected to the output shaft of the motor via a conveyor belt. A rotating plate is fixedly connected to the outer wall of the rotating rod.

[0013] As a further description of the above technical solution:

[0014] The filter plate is installed at an angle, and the height of the left side of the filter plate is lower than the height of the right side.

[0017] As a further description of the above technical solution:

[0018] The inclined plate has a parallelogram-shaped cross section, and the front and rear ends of the inclined plate are provided with pivots, which are located inside the housing.

[0019] As a further description of the above technical solution:

[0020] The inner wall of the housing located outside the pivot on both sides of the inclined plate has a cylindrical groove, and the torsion spring has a torque less than the elastic force of the spring sheet.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by setting up a conveyor belt, a feeding plate, a spring, an inclined plate, a torsion spring, a directional control plate, and a filter plate, it is ensured that larger waste particles that cannot pass through the filter plate can move to the left in the inclined state of the filter plate, and move upward by the feeding plate driven upward by the conveyor belt, thereby re-entering the crushing area. This achieves the effect of ensuring that the waste can be crushed well, ensuring that the reheating and melting time is short, and improving the processing efficiency when reused.

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 , Figure 2 and Figure 6 This utility model provides an embodiment of a waste material processing device for the production of PVC flame-retardant sleeves, comprising a housing 1. An opening communicating with the outside is provided on the upper right side of the housing 1, ensuring that workers can place the waste material from the production of PVC flame-retardant sleeves into the housing 1. A crushing assembly 2 is provided inside the housing 1, including a motor 21. When the motor 21 is energized, its output shaft can rotate. The motor 21 is fixedly connected to the rear end of the housing 1. An installation chamber 22 is provided on the inner wall of the housing 1. The output shaft of the motor 21 passes through the housing 1 and is located on the inner wall of the rear side of the installation chamber 22. The output shaft of the motor 21 is fixedly connected to a gear 23. The inner wall of the installation chamber 22 is rotatably connected to a gear 24. Gear 23 and gear 24 mesh with each other. The size and number of teeth of gear 23 and gear 24 are the same. The front end of gear 23 is fixedly connected to a crushing roller 25. There are two crushing rollers 25. The shaft of the other crushing roller 25 is fixedly connected to the front end of gear 24. The crushing roller 25 is composed of a cylindrical shaft in the middle connected to multiple blades on the outside.

[0035] Reference Figure 2 An operating chamber 4 is provided on the inner wall of the housing 1. The upper right side of the operating chamber 4 is trapezoidal in shape, and the upper space of the trapezoidal groove is larger than the lower space. The lower right side of the operating chamber 4 is rectangular in shape, and the area between the trapezoid and the rectangle is rectangular in shape with the same width as the lower width of the trapezoidal area. This area is located above the two crushing rollers 25, and the midpoint of this area is exactly between the two crushing rollers 25. The rotation shaft of the crushing roller 25 passes through the inner wall between the operating chamber 4 and the installation chamber 22.

[0036] Reference Figure 2 - Figure 4Inside the housing 1, located on the left side of the crushing assembly 2, is a conveying mechanism 3. The conveying mechanism 3 includes a conveyor belt 31. Inside the conveyor belt 31 are two rotating wheels rotatably connected to the inner wall of the housing 1. The conveyor belt 31 is taut. At the rear end of the housing 1 is an electric motor that drives the rotation inside the conveyor belt 31. A feeding plate 32, rectangular in shape, is rotatably connected to the outer wall of the conveyor belt 31. The left side of the operating chamber 4 is designed with a straight groove whose edge precisely matches the rotating shape of the edge of the feeding plate 32. A connecting hole is provided between the straight groove opening of the chamber 4 and the rectangular area on the lower right side. A connecting groove is provided between the upper part of the straight groove opening of the operating chamber 4 and the trapezoidal area on the upper right side. The outer wall of the feeding plate 32 and the outer wall of the conveyor belt 31 are elastically connected by a spring piece 33. One end of the spring piece 33 is fixedly connected to the outer wall of the feeding plate 32, and the other end of the spring piece 33 is fixedly connected to the outer wall of the conveyor belt 31. An inclined plate 35 is rotatably connected to the inner wall of the housing 1. The cross-sectional shape of the inclined plate 35 is a parallelogram, and the front and rear ends of the inclined plate 35 are provided with a rotating shaft.

[0037] Reference Figure 3 and Figure 7 The pivot of the inclined plate 35 is located inside the housing 1. The position of the pivot ensures that there are no protruding pivots on the upper surface of the inclined plate 35, thus preventing materials from falling inconveniently due to protrusions. The pivot of the inclined plate 35 is elastically connected to the inner wall of the housing 1 via a torsion spring 36. One end of the torsion spring 36 is fixedly connected to the outer wall of the pivot of the inclined plate 35, and the other end of the torsion spring 36 is fixedly connected to the inner wall of the housing 1 outside the pivot of the inclined plate 35. Cylindrical grooves are formed on the inner wall of the housing 1 outside the pivot on both the front and rear sides of the inclined plate 35. The torque of 6 is less than the elastic force of the spring 33. The inner wall of the operating chamber 4 is fixedly connected to the control plate 37. The control plate 37 is set in the straight groove part of the operating chamber 4, inside the right side area of ​​the conveyor belt 31. The distance between the two feeding plates 32 is greater than the distance between the control plate 37 and the inclined plate 35. The shape of the control plate 37 is concave. By setting the shape of the control plate 37, it is ensured that the front and rear ends of the control plate 37 can contact the outer wall of the feeding plate 32, while the middle part will not contact the feeding plate 32. Therefore, it is ensured that the waste material above the feeding plate 32 has space to move downward.

[0038] Reference Figure 2 , Figure 5 and Figure 6The housing 1 is equipped with a pusher assembly 5, which includes a rotating rod 51. The rotating rod 51 is cylindrical and is connected to the output shaft of the motor 21 via a second conveyor belt 52. The second conveyor belt 52 enables the output shaft of the motor 21 to not only drive the gear 23 to rotate, but also drive the rotating rod 51 to rotate via the second conveyor belt 52. The output shaft of the motor 21 is cylindrical, and the second conveyor belt 52 is located on the side of the output shaft of the motor 21. The position of the second conveyor belt 52 ensures that it can contact the output shaft of the motor 21 without affecting the fixing effect between the motor 21 and the gear 23. A rotating plate 53 is fixedly connected to the outer wall of the rotating rod 51.

[0039] Reference Figure 1 , Figure 2 and Figure 6 A filter plate 6 is fixedly connected to the inner wall of the operating chamber 4. Filter holes are opened on the top of the filter plate 6. The filter plate 6 is installed at an angle, and the left side of the filter plate 6 is lower than the right side. By installing the filter plate 6 at an angle, it is ensured that the material above the filter plate 6 can move to the left. A drawer 7 is slidably connected to the inner wall of the housing 1 below the filter plate 6. The drawer 7 can receive the waste fragments of the filtered PVC flame-retardant sleeve.

[0040] Working principle: When in use, the staff put the waste generated from the production of PVC flame retardant pipes into the shell 1 through the upper right opening of the shell 1. At this time, the waste moves downward under the action of gravity and enters the position between the two crushing rollers 25.

[0041] Since motor 21 drives gear 23 to rotate, and gear 23 drives gear 24 to rotate, and since gear 23 and gear 24 are the same size and have the same number of teeth, gear 23 and gear 24 rotate in opposite directions at the same speed. This drives the two crushing rollers 25 to move in opposite directions, thereby achieving the effect of cutting waste material through the blades of the two crushing rollers 25 approaching each other.

[0042] After the waste material passes through the area between the two crushing rollers 25, it falls above the filter plate 6. Because the waste material has gravity, it can drive the filter plate 6 to vibrate during the falling process through the force of its original fall.

[0043] At this time, waste that is large enough to pass through the filter plate 6 passes through the filter plate 6 and falls into the drawer 7, while waste that cannot pass through moves to the left side of the operating chamber 4 under the continuous vibration of the filter plate 6.

[0044] As the conveyor belt 31 drives the feeding plate 32 to move upward, the feeding plate 32 can carry the waste material upward during the upward movement. Since the left inner wall of the operating chamber 4 is consistent with the outer path of the feeding plate 32, even if the upper part of the feeding plate 32 is deflected due to a large amount of waste, the waste material above it can fall to the path of the next feeding plate 32, so the waste material can still be carried upward.

[0045] Since the elastic force of the spring 33 is greater than the torsion force of the torsion spring 36, when the feeding plate 32 contacts the inclined plate 35, it pushes the inclined plate 35, causing it to deflect. When the feeding plate 32 moves upward and leaves the inclined plate 35, the inclined plate 35 returns to its original position under the action of the torsion spring 36. Since the distance between the inclined plate 35 and the control plate 37 is less than the distance between two feeding plates 32, before the next feeding plate 32 pushes the inclined plate 35, the feeding plate 32 first contacts the control plate 37 and is subjected to the pressure of the control plate 37, so that its right end cannot move due to the pressure, while its left end is carried upward by the conveyor belt 31, so that the whole is tilted to the right. Therefore, the material above it falls under the action of gravity after the feeding plate 32 tilts, and enters the upper right area of ​​the operating chamber 4 again under the action of the inclined plate 35, thus entering the cycle.

[0046] Meanwhile, as the motor 21 rotates, it also drives the conveyor belt 52 to move, which in turn causes the rotating rod 51 to rotate. This causes the rotating plate 53 to rotate under the drive of the rotating rod 51, so that the rotating plate 53 can squeeze the waste material as it rotates downwards. This prevents some cylindrical waste material from getting stuck between the two crushing rollers 25 and being unable to be crushed.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
