[0001] The invention relates to the technical field of polyvinyl chloride recovery, in particular to a polyvinyl chloride insulation product crushing and recovery device. Background Art

In order to ensure the recycling of resources, it is usually necessary to crush and recycle the scrapped insulation products, thereby playing an environmental protection role.

[0004] However, since the wire sheaths are mostly long elastic round tubes, they are easily squeezed and deformed by the crushing wheel during the crushing process. Then, as the crushing wheel of the crusher moves, the wire sheaths cannot be completely crushed, affecting the recycling efficiency. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art that most of the wire sheaths are long elastic round tubes, which are easily squeezed and deformed by the crushing wheel during the crushing process, and then move with the crushing wheel of the crusher, resulting in the sheath wire cannot be completely crushed, affecting the recycling efficiency, and a polyvinyl chloride insulation product crushing and recycling equipment is proposed.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A polyvinyl chloride insulation product crushing and recycling device, comprising: a mounting frame, a motor and a crushing device arranged in the middle of the mounting frame, a material guide assembly is arranged above the mounting frame, and the material guide assembly is arranged above the crushing device;

[0008] The material guide assembly includes a material guide shell and a material guide roller. The material guide shell is an arc-shaped shell, and the bottom is fixedly connected to the mounting frame. The discharge port is located directly above the crushing device, and the feed port is arranged horizontally. The material guide roller is slidably installed inside the material guide shell through an elastic member, and is used for guiding the movement of the product.

[0009] A toggle assembly is provided inside the material guide shell, and the toggle assembly is arranged on the side of the material guide roller away from the feed port. The toggle assembly includes a rotating rod and a toggle rod. The rotating rod is rotatably installed on the inner side of the material guide shell, the rotating rod is arranged parallel to the material guide roller, and the end of the rotating rod and the middle of the material guide roller are located on the same horizontal line. The toggle rod is vertically fixedly connected to the end of the rotating rod, and the rotation of the toggle rod drives the material guide roller to move downward.

[0010] Preferably, the crushing device includes two crushing wheels, two driving shafts and two interlocking gears, the two crushing wheels are fixedly mounted on the two driving shafts respectively, the two interlocking gears are fixedly mounted on the ends of the driving shafts and are meshedly connected, and one side of the driving shaft is fixedly connected to the output end of the motor.

[0011] Preferably, a speed changing device is provided on the side of the material guide shell, and the speed changing device is used to drive the rotating rod to reduce the speed. The speed changing device includes a gearbox and a driving gear. The gearbox is fixedly mounted on the side of the material guide shell, and the bottom is meshed with the linkage gear. The driving gear is fixedly mounted on the end of the rotating rod and is meshed with the inside of the gearbox.

[0012] Preferably, the material guide roller includes a shaft and two sleeves, the two sleeves are symmetrically rotatably sleeved on the shaft, and a toggle ring is formed in the middle, the width of the toggle ring is greater than the width of the toggle rod, the toggle rod is made of elastic material, and the length of the toggle rod is greater than the spacing length between the material guide roller and the rotating rod.

[0013] Preferably, a limiting component is provided inside the feed port of the material guide shell, and the limiting component is used to limit the position of the pipe product.

[0014] Preferably, the limiting assembly includes a lower plate, an upper plate and a plurality of spring columns, the lower plate is fixedly connected to the bottom wall of the feed port, the plurality of spring columns are equidistantly fixedly connected to the top wall of the feed port, the upper plate is fixedly connected to the bottom ends of the plurality of spring columns, and a plurality of limiting openings are opened between the upper plate and the lower plate.

[0015] Preferably, the limiting opening is a truncated cone-shaped opening, and the end with a larger bottom surface faces the outside of the material guide shell, and a plurality of elastic limiting strips are annularly arranged inside the limiting opening.

[0016] Preferably, two strip grooves are symmetrically opened on both sides of the material guide shell, and the elastic member is arranged inside the strip groove. The elastic member includes two connecting blocks and a spring tube. The spring tube is fixedly connected between the two connecting blocks, and the upper connecting block is fixedly connected to the bottom surface of the shaft rod.

[0017] Preferably, two linkage plates are fixedly connected between the shaft rod and the upper plate, the linkage plates are arc-shaped plates, and the two linkage plates are symmetrically arranged, and when the shaft rod moves downward, the upper plate is driven to move downward.

[0018] Preferably, a guide wheel is rotatably connected between the two linkage plates, and the guide wheel is used to deflect the pipe component product.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The guide shell arranged horizontally at the feed end can control the introduction speed of the wire hose. After the wire hose is introduced into the guide shell, it is deflected and guided by the guide roller during the movement, so that the end portion enters the crushing device. However, the other end is arranged horizontally, which reduces the moving speed of the wire hose and prolongs the contact time between the part to be crushed and the crushing device, thereby improving the crushing effect.

[0021] When the wire hose at the bottom is crushed, the downward-pressed guide roller will drive the wire hose to move downward, and the wire hose will be forced to move downward, increasing the crushing area between the wire hose and the crushing device. It does not need to be pushed manually, and the wire hose will be automatically driven downward to ensure the crushing process, thereby improving the crushing efficiency of the wire hose.

[0022] The speed change device can control the rotation speed of the rotating rod, thereby adjusting the speed of the downward clearance of the guide roller by controlling the rotation speed of the internal toggle assembly, which is suitable for the crushing of wire hoses of different diameters and thicknesses;

[0023] The multiple spring columns can be used to elastically clamp the wire hoses of different diameters. When the wire hoses are crushed, the wire hoses are subjected to the twisting force of the crushing device, and the elastic clamping can block the upper end of the wire hoses, reducing the speed of the wire hoses moving downward, thereby extending the time that the crushing part of the wire hoses is between the two crushing wheels, and enhancing the crushing effect of the wire hoses;

[0024] The downward movement of the guide roller will drive the upper plate to move downward, so that the wire hose in the middle is fixed and clamped by the upper and lower plates, so that the wire hose located between the two crushing wheels is fixed and will not move downward, thereby enhancing the crushing effect of the crushing wheels on the wire hose;

[0025] Since the linkage plate fixes the shaft rod and the upper plate, when the wire hose is introduced, the upper plate will be propped up because the diameter of the wire hose is larger than the diameter of the limit opening. During the upper movement of the upper plate, the shaft rod will be driven upward through the linkage plate, and the guide roller will adjust its position according to the wire hoses of different diameters, thereby adapting to the guide position of wire hoses of different diameters.

DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0037] The terms such as "upper", "lower", "left", "right", "middle" and "one" used in the present invention are only for the convenience of description and are not used to limit the scope of the present invention. Changes or adjustments to their relative relationships should be regarded as the scope of the present invention without substantially changing the technical content.

[0038] Reference Figure 1-Figure 9 , a polyvinyl chloride insulation product crushing and recycling device, comprising: a mounting frame 1, a motor 2 and a crushing device 5 arranged in the middle of the mounting frame 1, a material guide component 3 is arranged above the mounting frame 1, and the material guide component 3 is arranged above the crushing device 5;

[0039] The material guide assembly 3 includes a material guide shell 31 and a material guide roller 32. The material guide shell 31 is an arc-shaped shell, and the bottom is fixedly connected to the mounting frame 1. The discharge port is located directly above the crushing device 5, and the feed port is arranged horizontally. The material guide roller 32 is slidably installed inside the material guide shell 31 through an elastic member 9, and is used for guiding the movement of the product.

[0040] A toggle assembly 4 is provided inside the material guide shell 31, and the toggle assembly 4 is arranged on the side of the material guide roller 32 away from the feed port. The toggle assembly 4 includes a rotating rod 41 and a toggle rod 42. The rotating rod 41 is rotatably installed on the inner side of the material guide shell 31, and the rotating rod 41 is arranged parallel to the material guide roller 32, and the end of the rotating rod 41 is located on the same horizontal line as the middle of the material guide roller 32. The toggle rod 42 is vertically fixedly connected to the end of the rotating rod 41, and the rotation of the toggle rod 42 drives the material guide roller 32 to move downward.

[0041] In the embodiment of the application of the above technical solution, the vertically introduced electric wire hose will move down quickly under the action of gravity, and the speed cannot be controlled, which affects the crushing effect. The guide shell 31 horizontally arranged at the feed end can control the introduction speed of the electric wire hose. Since the electric wire hose is elastic, it will bend. After the electric wire hose is introduced into the guide shell 31, it is deflected and guided by the guide roller 32 during the movement, so that the end portion enters the crushing device 5, but the other end is arranged horizontally, which reduces the moving speed of the electric wire hose and prolongs the contact time between the part to be crushed and the crushing device 5, thereby improving the crushing effect.

[0042] When the electric wire hose at the bottom is crushed, the contact area between the electric wire hose and the crushing device 5 is reduced, and the electric wire hose needs to be moved downward. The rotating rod 41 will drive the toggle rod 42 to rotate during the rotation process. The toggle rod 42 will move the guide roller 32 downward from the upper side during the rotation process. The downward pressed guide roller 32 will drive the electric wire hose to move downward. The electric wire hose is forced to move downward, thereby increasing the crushing area between the electric wire hose and the crushing device 5. There is no need for manual pushing, and the electric wire hose is automatically driven downward to ensure the crushing process, thereby improving the crushing efficiency of the electric wire hose.

[0043] The invention improves the efficiency of crushing tubular polyvinyl chloride insulation products and ensures the crushing effect.

[0044] The preferred technical solution in this embodiment is:

[0045] Reference Figure 3 The crushing device 5 includes two crushing wheels 51, two driving shafts 52 and two linkage gears 53. The two crushing wheels 51 are fixedly mounted on the two driving shafts 52 respectively. The two linkage gears 53 are fixedly mounted on the ends of the driving shafts 52 and are meshedly connected. One side of the driving shaft 52 is fixedly connected to the output end of the motor 2.

[0046] The driving shaft 52 on one side is driven to rotate by a high-power motor 2, and the two driving shafts 52 rotate synchronously through meshing gears. The two rotating crushing wheels 51 crush the insulating pipe made of polyvinyl chloride introduced into the middle.

[0047] Reference Figure 4 A speed change device 6 is provided on the side of the material guide shell 31, and the speed change device 6 is used to drive the rotating rod 41 to rotate at a reduced speed. The speed change device 6 includes a gearbox 61 and a driving gear 62. The gearbox 61 is fixedly installed on the side of the material guide shell 31, and the bottom is meshed with the linkage gear 53. The driving gear 62 is fixedly installed on the end of the rotating rod 41 and is meshed with the inside of the gearbox 61.

[0048] In order to achieve energy conservation and environmental protection, the speed change of the gearbox 61 belongs to the commonly used existing technology. The speed is reduced by multiple speed gears of different sizes inside the gearbox 61. The high-speed rotation of the bottom linkage gear 53 is reduced by the speed change of multiple speed gears, and the driving gear 62 is rotated at a reduced speed. The rotating drive gear 62 then drives the rotating rod 41, thereby realizing the control of multiple speeds through a single motor 2, reducing energy consumption.

[0049] The speed change device 6 can control the rotation speed of the rotating rod 41, thereby adjusting the speed of the downward clearance of the guide roller 32 by controlling the rotation speed of the internal toggle assembly 4, which is suitable for the crushing of wire hoses of different diameters and thicknesses.

[0050] Reference Figure 5-6 The material guide roller 32 includes a shaft rod 321 and two sleeves 322. The two sleeves 322 are symmetrically rotatably sleeved on the shaft rod 321, and a toggle ring is formed in the middle. The width of the toggle ring is greater than the width of the toggle rod 42. The toggle rod 42 is made of elastic material, and the length of the toggle rod 42 is greater than the spacing length between the material guide roller 32 and the rotating rod 41.

[0051] Both ends of the shaft rod 321 are fixedly connected to two elastic members 9. When the sleeve 322 is subjected to force, it rolls, driving the wire hose to move. A plurality of racks are provided on the sleeve 322 to facilitate contact with the wire hose, and the wire hose is driven downward when rotating.

[0052] When the guide roller 32 is toggled, the toggle rod 42 is used to toggle from the toggle ring in the middle of the guide roller 32, so as to ensure uniform force on both sides and ensure that the downward force on the wire hose under the guide roller 32 is the same, so that multiple wire hoses can be crushed synchronously, avoiding incomplete crushing due to different pressures and different crushing conditions.

[0053] Reference Figure 7-8 A limiting component 7 is provided inside the feed port of the guide shell 31, and the limiting component 7 is used to limit the position of the pipe product;

[0054] The limiting assembly 7 includes a lower plate 71, an upper plate 72 and a plurality of spring columns 73, wherein the lower plate 71 is fixedly connected to the bottom wall of the feed port, the plurality of spring columns 73 are fixedly connected to the top wall of the feed port at equal distances, the upper plate 72 is fixedly connected to the bottom ends of the plurality of spring columns 73, and a plurality of limiting openings are opened between the upper plate 72 and the lower plate 71;

[0055] The limiting opening is a truncated cone-shaped opening, and the end with a larger bottom surface faces the outside of the material guide shell 31. A plurality of elastic limiting strips 8 are annularly arranged inside the limiting opening.

[0056] When the electric wire hose is crushed, due to its own shape and toughness, the electric wire hose will move downward due to its own gravity and the rolling and squeezing of the crushing wheel 51 when not fixed by external force, resulting in the electric wire hose being unable to be completely crushed by the crushing wheel 51. After crushing, there are a large number of strip-shaped crushed pieces, which reduces the crushing effect.

[0057] The limiting component 7 increases the friction force on the wire hose through the clamping effect between the upper plate 72 and the lower plate 71, thereby restricting the movement of the wire hose. Since wire hoses of different specifications have different diameters, in order to ensure the limiting effect of the wire hose, a truncated cone-shaped limiting opening is set, and wire hoses of different diameters can be elastically clamped by multiple spring columns 73. When the wire hose is crushed, since the wire hose is subjected to the twisting force of the crushing device 5, the elastic clamping can block the upper end of the wire hose and reduce the speed at which the wire hose moves downward, thereby extending the time that the crushing part of the wire hose is between the two crushing wheels 51, thereby enhancing the crushing effect of the wire hose.

[0058] During the crushing process, the guide roller 32 will move downward under the squeezing action of the toggle rod 42, and the downward movement of the guide roller 32 will drive the upper plate 72 to move downward, so that the wire hose in the middle is fixedly clamped by the upper plate 72 and the lower plate 71, so that the wire hose located between the two crushing wheels 51 is fixed and will not move downward, thereby enhancing the crushing effect of the crushing wheel 51 on the wire hose;

[0059] As the rotating rod 41 rotates, the elastic toggle rod 42 can be deformed and separated from the guide roller 32. After the toggle rod 42 is separated from the shaft 321, the guide roller 32 is reset upward under the elastic action of the elastic member 9, so that the downward pressure on the upper plate 72 disappears. At this time, the wire hose will move downward under the twisting action of the crushing wheel 51, and the new crushed part will be transferred to the inside of the crushing wheel 51 for further crushing.

[0060] Reference Figure 5-8 The guide shell 31 has two strip grooves symmetrically formed on both sides, and the elastic member 9 is arranged inside the strip groove. The elastic member 9 includes two connecting blocks 91 and a spring tube 92. The spring tube 92 is fixedly connected between the two connecting blocks 91. The upper connecting block 91 is fixedly connected to the bottom surface of the shaft rod 321.

[0061] Two linkage plates 10 are fixedly connected between the shaft rod 321 and the upper plate 72 . The linkage plates 10 are arc-shaped plates, and the two linkage plates 10 are symmetrically arranged. When the shaft rod 321 moves downward, the upper plate 72 is driven to move downward.

[0062] The elastic members 9 on both sides are provided to ensure the reset of the material guide roller 32. The material guide roller 32 is provided in the middle of the two strip grooves. Since the linkage plate 10 fixes the shaft rod 321 and the upper plate 72, when the wire hose is introduced, since the diameter of the wire hose is larger than the diameter of the limit opening, the upper plate 72 will be propped up. During the upward movement of the upper plate 72, the shaft rod 321 will be driven upward through the linkage plate 10. The material guide roller 32 will adjust its position according to the wire hoses of different diameters, so as to adapt to the guiding position of the wire hoses of different diameters, and avoid the wire hose passing through the top of the material guide roller 32 or pressing against the material guide roller 32, resulting in the material guide roller 32 being unable to guide normally.

[0063] The stretchable spring tube 92 can be deformed when the shaft rod 321 moves upward to adapt to the position adjustment of the shaft rod 321. At the same time, after the shaft rod 321 is squeezed and moved downward, it can be reset under the elastic action of the spring tube 92 to ensure the next squeezing.

[0064] Reference Figure 7-8 A guide wheel 11 is rotatably connected between the two linkage plates 10, and the guide wheel 11 is used to deflect the pipe component product.

[0065] The guide wheel 11 is provided to assist the movement of the wire hose. The guide wheel 11 can be adjusted in position to be suitable for wire hoses of different diameters. The guide wheel 11 is provided below the wire hose, and the guide roller 32 is provided above the wire hose. By providing the two wheels, the movement range of the wire hose is limited to a certain area, ensuring that the wire hose will not have a large position deviation during movement, thereby ensuring the normal movement of the wire hose under the twisting action of the crushing wheel 51.

[0066] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
