Description

Technical Field

[0001] This solution belongs to the field of waste recycling technology, specifically involving a waste recycling device for polyurethane board processing. Background Technology

[0002] Utility model patent CN221985554U discloses a waste recycling device for polyurethane production and processing, including a support frame. A screening mechanism is installed on the frame wall of the support frame. The screening mechanism is composed of a fixed block, a spring rod, a vibrator, a collection box, and honeycomb holes. The fixed block is welded to the frame wall of the support frame. The wall of the fixed block is fixedly connected to the wall of the collection box by the spring rod. The vibrator is bolted to the frame wall of the support frame, and the column of the vibrator is located at the top of the collection box. The bottom of the collection box has filtered honeycomb holes, which cause the column to drive the collection box to vibrate. As a result, the pulverized polyurethane falls into the outer box through the honeycomb holes, thereby enabling the pulverized polyurethane to be screened and collected.

[0003] However, the device has certain shortcomings. During the recycling and crushing process of polyurethane board waste, the crushed material is prone to breakage and flying, which poses a safety hazard. At the same time, the crushed material is not easy to screen. Utility Model Content

[0004] The purpose of this solution is to provide a waste recycling device for the processing of polyurethane boards, in order to solve the problems that, during the recycling and crushing process of polyurethane board waste, the fragments are easily broken and scattered, creating safety hazards, and that the fragments are not easy to screen.

[0005] To achieve the above objectives, this solution provides a waste recycling device for polyurethane board processing, including a support, a crushing box fixedly connected to the upper end of the support, a rotating roller inside the crushing box, a crushing blade fixedly connected to the outer side of the rotating roller, a material guiding mechanism inside the crushing box, a cover in contact with the upper end of the support, the cover and the crushing box being slidably connected, and a screening mechanism inside the support.

[0006] The principle of this solution is as follows: During use, the drive mechanism of the two rotating rollers is activated, causing the two rotating rollers to rotate relative to each other. Then, the polyurethane waste material is placed on the baffle, causing the baffle to rotate under pressure, which in turn causes the polyurethane waste material to fall into the crushing chamber. The rotating baffle presses against the top block, causing the top block to move downwards. The downward movement of the top block presses against the spring, causing the spring to be compressed. When all the polyurethane waste material has fallen off the baffle, the spring returns to its original position, causing the top block to return to its original position. This causes the top block to press against the baffle, which in turn returns to its original position, bringing the two baffles into contact and sealing the upper part of the crushing chamber, preventing the polyurethane waste material from splashing out and creating a safety hazard. The motor is then activated, driving the square rod to rotate, which in turn causes the square cylinder to rotate. The square cylinder drives the filter cover to rotate, causing the inclined block to move. The movement of the inclined block and its collision with the baffle cause the filter cover to vibrate. At the same time, the rotation of the filter cover creates a centrifugal motion, which makes the screened polyurethane pulverized material easier to screen and discharge, and the filter cover is less prone to clogging, making the screening more efficient. The screened fragments are discharged through the guide plate and the material channel.

[0007] The technical advantage of this solution is that the spring acts on the top block, which allows the two baffles to automatically reset after the material is fed in, thus sealing the top of the crushing box and preventing polyurethane board waste from breaking and splashing during the crushing process, which could cause safety hazards.

[0008] The motor drives the square rod to rotate, which in turn causes the square cylinder to rotate the filter cover. The collision of the inclined block and the stop block causes the filter cover to vibrate. At the same time, the rotation of the filter cover causes centrifugal motion, which makes it easier to screen and discharge the pulverized polyurethane material after screening. The filter cover is also less prone to clogging, making screening more efficient.

[0009] Furthermore, the support has a guide groove inside, and a material channel is fixedly connected to the surface of the support. The material channel guides the discharge of the broken material.

[0010] Furthermore, the material guiding mechanism includes baffles. Two mutually contacting baffles are hinged inside the crushing chamber. A support plate is fixedly connected inside the crushing chamber, and a top rod is slidably connected inside the support plate. A top block is fixedly connected to the upper end of the top rod, and the top block contacts the baffles. A spring is provided on the outer side of the top rod. The spring acts on the top block, causing the two baffles to automatically reset after material feeding, sealing the upper part of the crushing chamber and preventing polyurethane board waste from shattering and splashing during crushing, thus avoiding safety hazards.

[0011] Furthermore, a baffle is fixedly connected inside the crushing chamber, and the baffle contacts the baffle plate. By setting the baffle, the baffle plate is sealed off.

[0012] Furthermore, one end of the spring is fixedly connected to the support plate, and the other end of the spring is fixedly connected to the top block. By setting the spring, the top block can be easily reset.

[0013] Furthermore, the screening mechanism includes a support plate, which is fixedly connected inside the support. A motor is fixedly installed at the lower center of the support plate, and the motor's shaft passes through and is rotatably connected to the support plate. A square rod is fixedly connected to the upper end of the motor's shaft, and a square cylinder is slidably connected to the outer side of the square rod. A filter cover is fixedly connected to the upper end of the square cylinder, and the filter cover is movably connected to the support. An inclined block is fixedly connected to the lower end of the filter cover, and a guide plate is fixedly connected inside the support. The motor drives the square rod to rotate, which in turn causes the square cylinder to rotate the filter cover. This causes the inclined block and the stop block to collide, resulting in vibration of the filter cover. Simultaneously, the rotation of the filter cover induces centrifugal motion, making it easier to screen and discharge the pulverized polyurethane material after screening. Furthermore, the filter cover is less prone to clogging, resulting in more efficient screening.

[0014] Furthermore, a stop block is fixedly connected inside the support, and the stop block and the inclined block are slidably connected. By setting the stop block and the inclined block to cooperate, the filter cover can vibrate. Attached Figure Description

[0021] The implementation examples are basically as follows Figure 1 , Figure 2As shown, this embodiment provides a waste recycling device for polyurethane board processing, including a support 1, a crushing box 2 fixedly connected to the upper end of the support 1, a rotating roller 3 inside the crushing box 2, a crushing blade 4 fixedly connected to the outer side of the rotating roller 3, a material guiding mechanism 5 inside the crushing box 2, a cover 6 in contact with the upper end of the support 1, the cover 6 and the crushing box 2 being slidably connected, a screening mechanism 7 inside the support 1, a material guiding groove 8 inside the support 1, and a material channel 9 fixedly connected to the surface of the support 1. The material channel 9 guides the discharge of the crushed material.

[0022] like Figure 1 , Figure 2 , Figure 3 As shown, the material guiding mechanism 5 includes baffles 51. Two baffles 51 are hinged inside the crushing box 2 and contact each other. A baffle bar 52 is fixedly connected inside the crushing box 2 and contacts the baffles 51. By setting the baffle bar 52, the baffles 51 are closed. A support plate 53 is fixedly connected inside the crushing box 2. A top rod 54 is slidably connected inside the support plate 53. A top block 55 is fixedly connected to the upper end of the top rod 54 and contacts the baffles 51. A spring 56 is set on the outside of the top rod 54. One end of the spring 56 is fixedly connected to the support plate 53, and the other end of the spring 56 is fixedly connected to the top block 55. By setting the spring 56, the top block 55 can be easily reset. By the spring 56 acting on the top block 55, the two baffles 51 can be automatically reset after material feeding, sealing the upper end of the crushing box 2 and preventing polyurethane board waste from breaking and splashing during the crushing process, thus avoiding safety hazards.

[0023] like Figure 1 , Figure 4 As shown, the screening mechanism 7 includes a support plate 71. The support plate 71 is fixedly connected inside the support 1. A motor 72 is fixedly installed at the lower middle of the support plate 71. The rotating shaft of the motor 72 passes through the support plate 71 and is rotatably connected to the support plate 71. A square rod 73 is fixedly connected to the upper end of the rotating shaft of the motor 72. A square cylinder 74 is slidably connected to the outer side of the square rod 73. A filter cover 75 is fixedly connected to the upper end of the square cylinder 74. The filter cover 75 is movably connected to the support 1. An inclined block 76 is fixedly connected to the lower end of the filter cover 75. The support 1 is fixedly connected inside the support. There is a stop block 77, which is slidably connected to the inclined block 76. By setting the stop block 77 and the inclined block 76 to cooperate, the filter cover 75 can vibrate. The support 1 is fixedly connected to the inside of the guide plate 78. The square rod 73 is driven to rotate by the motor 72, which in turn causes the square cylinder 74 to drive the filter cover 75 to rotate. The inclined block 76 and the stop block 77 collide, causing the filter cover 75 to vibrate. At the same time, the rotation of the filter cover 75 makes centrifugal motion, which makes it easier to screen and discharge the pulverized polyurethane after screening. The filter cover 75 is not easy to clog, and the screening is more efficient.

[0024] The specific implementation process of this utility model is as follows: In use, the drive mechanism of the two rotating rollers 3 is activated, causing the two rotating rollers 3 to rotate relative to each other. Then, the polyurethane board waste is placed on the baffle 51, causing the baffle 51 to rotate under pressure, thereby causing the polyurethane board waste to fall into the crushing box 2. The baffle 51 rotates and presses the top block 55, thereby causing the top block 55 to move downward. The downward movement of the top block 55 presses the spring 56, causing the spring 56 to be compressed. When all the polyurethane board waste has fallen off the baffle 51, the spring 56 returns to its original position, causing the top block 55 to return to its original position, thereby causing the top block 55 to push against the baffle 51, and thus the baffle 51... 1. Reset, thereby bringing the two baffles 51 into contact and sealing the upper end of the crushing box 2 to prevent polyurethane board waste from splashing out and causing safety hazards. Start the motor 72, which drives the square rod 73 to rotate, thereby causing the square cylinder 74 to rotate. The square cylinder 74 drives the filter cover 75 to rotate, causing the inclined block 76 to move. The movement of the inclined block 76 and the collision with the baffle 77 cause the filter cover 75 to vibrate. At the same time, the rotation of the filter cover 75 makes centrifugal motion, which makes it easier to screen and discharge the sieved polyurethane pulverized material, and the filter cover 75 is not easy to clog, making the screening more efficient. The sieved fragments are discharged through the guide plate 78 and the material channel 9 respectively.

[0025] The spring 56 acts on the top block 55, which allows the two baffles 51 to automatically reset after the material is fed in, thus sealing the upper end of the crushing box 2 and preventing the polyurethane board waste from breaking and splashing during the crushing process, which could cause safety hazards.

[0026] The motor 72 drives the square rod 73 to rotate, which in turn causes the square cylinder 74 to drive the filter cover 75 to rotate. This causes the inclined block 76 and the stop block 77 to collide, causing the filter cover 75 to vibrate. At the same time, the rotation of the filter cover 75 creates a centrifugal motion, which makes it easier to screen and discharge the pulverized polyurethane material after screening. The filter cover 75 is also less prone to clogging, making screening more efficient.
