Description

Technical Field

[0001] The present invention relates to the technical field of vacuum bag film processing equipment, and in particular to a vacuum bag film production and processing device and process. Background Art

[0002] Vacuum bag film refers to a process auxiliary material that is solidified and formed with composite components. It is a thin film material that can form and maintain a vacuum state under certain environmental conditions. When producing and processing vacuum bag film, it is necessary to first crush the raw material particles of the vacuum bag film, then melt the crushed raw material particles, and then process the liquid raw material into vacuum bag film.

[0003] Prior art includes an invention with publication number CN111002520B, which discloses a polyester film processing device and method, comprising a conveyor frame, a crushing box assembly, a crushing wheel assembly, a width adjustment mechanism, a carriage, a rolling mechanism, and a tensioning mechanism. The invention has the beneficial effect of rolling plastic film, resulting in a uniform composition of the formed film, and the width and thickness of the formed film can be controlled. The process is as follows: 1. Plastic particles for processing plastic film are placed into a feed box; 2. The crushing wheel assembly is activated to grind large plastic particles; 3. The large plastic particles are ground into fine particles and fall into a crushing drum, which heats and melts the fine particles, and the liquid plastic flows out through the width adjustment mechanism; 4. The crushing wheel assembly drives the rolling mechanism to rotate via two tensioning mechanisms, which rolls the discharged plastic film, and a blower cools and shapes the rolled film; 5. The formed plastic film is discharged through the conveyor frame.

[0004] In view of the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: when using the above-mentioned processing device to crush the vacuum bag film raw material particles, the vacuum bag film raw material particles will be crushed with the help of a crushing wheel group, but in actual application, it is easy for some vacuum bag film raw material particles to fail to be fully crushed after being squeezed. When the vacuum bag film raw material particles are subsequently melted, it is difficult to ensure that the vacuum bag film raw material particles are evenly melted, which in turn affects the subsequent production of vacuum bag film.

[0005] To this end, we propose a vacuum bag film production and processing device and process. Summary of the Invention

[0006] The object of the present invention is to provide a vacuum bag film production and processing device and process to solve the problems raised in the above background technology.

[0007] To achieve the above objectives, the present invention provides the following technical solutions: a vacuum bag film production and processing device and process, comprising a crushing box, wherein the inner wall of the crushing box is rotatably connected to two crushing rollers, and the outer wall of the crushing box is fixedly connected to two first motors, wherein the output ends of the first motors are fixedly connected to the crushing rollers, and further comprising:

[0008] The crushing box is provided with a plurality of crushing structures for screening the crushed raw material particles and performing secondary crushing. The crushing structure includes a screening plate detachably mounted in the crushing box, a storage box for lifting larger raw materials, a bidirectional screw for moving the storage box in a vertical direction, and a sliding block for moving along the arc surface of the bidirectional screw;

[0009] Auxiliary structures are respectively arranged on the inner wall of the crushing box, used to accelerate the powdered raw materials to pass through the screening plate, and the auxiliary structures include a rectangular frame fixedly installed on the inner wall of the crushing box, an air pump for sucking air, and a filter plate for filtering the air;

[0010] A cleaning structure is respectively arranged on the surface of the sliding block for cleaning the powdered raw materials attached to the arc surface of the bidirectional screw. The cleaning structure includes two telescopic rods fixedly installed on the surface of the sliding block, a circular tube for limiting the direction of air flow, and a hose for conveying air.

[0011] The effects achieved by the above components are as follows: by setting up a re-crushing structure, the raw material particles are screened with the help of a screening plate, the raw material particles of qualified volume will fall through the screening plate, and the raw material particles of larger volume will slide into the storage box, and the storage box is made to reciprocate in the vertical direction with the help of a bidirectional screw rod. When the storage box slides to a certain position, the raw material particles will be poured out, and the raw material particles are crushed for the second time by the crushing roller, thereby ensuring that the raw material particles can be melted evenly, which is convenient for the subsequent production of vacuum bag film. By setting up an auxiliary structure, the air in the crushing box is sucked by an air pump, and the raw material particles are crushed by the crushing roller. The air drives the powdered air to pass through the screening plate quickly, thereby improving the screening efficiency of the screening plate, and preventing the powdered raw materials from slipping into the storage box and occupying the internal space of the storage box as much as possible, thereby improving the space utilization efficiency of the storage box. By setting a cleaning structure, when the sliding block moves along the arc surface of the bidirectional screw, when the air pump is started, the air will flow through the hollow plate and be discharged by the circular tube. The air will blow away the powdered raw materials attached to the arc surface of the bidirectional screw, and try to prevent the powdered raw materials from hindering the movement of the sliding block along the arc surface of the bidirectional screw, thereby improving the stability of the bidirectional screw during operation.

[0012] The upper surface of the movable frame is fixedly provided with a U-shaped plate, and the lower surface of the movable frame is fixedly provided with a U-shaped plate.

[0013] The effect achieved by the above components is: when the vacuum bag film raw material particles need to be crushed, the appropriate screen plate is installed in the crushing box according to the required raw material particle size, the vacuum bag film raw material particles are poured into the crushing box, and then the output ends of the two first motors are controlled to rotate in opposite directions. The rotation of the output end of the first motor will drive the crushing roller to rotate. At this time, the two crushing rollers will squeeze the vacuum bag film raw material particles and crush the vacuum bag film raw material particles. After that, the crushed vacuum bag film raw material particles will fall onto the surface of the screen plate. Since the vertical cross-section of the screen plate is in the shape of a "human", the crushed raw material particles will slide along the surface of the screen plate. At this time, the screen plate will screen the raw material particles, and the raw material particles with qualified volume will fall through the screen plate, while the raw material particles with larger volume will continue to slide along the surface of the screen plate, and then the raw material particles with larger volume will continue to slide along the surface of the screen plate. The storage box will store larger raw material particles, and then the second motor will be started. The rotation of the output end of the second motor will drive the bidirectional screw to rotate, and the bidirectional screw will drive the sliding block to move upward with the help of the thread. The movement of the U-shaped plate with the help of the sliding block will drive the storage box to move synchronously. The storage box continues to move and the first elastic sheet will contact the lower surface of the long arm of the L-shaped plate. At this time, the long arm of the L-shaped plate will squeeze the first elastic sheet, and the first elastic sheet will stretch along the surface of the L-shaped plate until one end of the first elastic sheet extends to the top of the guide plate. Since the bottom of the inner wall of the storage box is a slope, the raw material particles will slide along the inner wall of the storage box to the surface of the first elastic sheet, and then the raw material particles will fall onto the surface of the guide plate and slide along the guide plate between the two crushing rollers, and the crushing rollers will be used to crush the raw material particles for the second time.

[0014] Preferably, the crushing box is fixedly connected to a rectangular plate relative to the rotating plate, and a second elastic sheet is fixedly connected between the rectangular plate and the rotating plate. A sealing piece is provided on the inner wall of the crushing box, and the sealing piece includes a support rod with both ends fixedly connected to the crushing box, a sealing plate is slidingly passed through the support rod, a groove is provided on the surface of the sealing plate, and an adjustment plate is slidably connected to the inner wall of the groove, and a bolt is threadedly connected to the surface of the sealing plate, and the bolt passes through the sealing plate and rests on the surface of the adjustment plate, and the vertical cross-section of the upper end of the sealing plate is an obtuse triangle.

[0015] The effect achieved by the above components is: during the movement of the storage box, the second elastic sheet gradually stretches, and the turn plate will rotate upward. At this time, the turn plate will block the raw material particles sliding along the surface of the screening plate, and try to prevent larger raw material particles from falling directly from the surface of the turn plate without secondary crushing. The second elastic sheet can automatically reset the turn plate, and the sealing member and the turn plate will cooperate to block the raw material particles sliding along the surface of the screening plate, and try to prevent larger raw material particles from falling directly from the surface of the turn plate without secondary crushing.

[0016] Preferably, two limiting rods are slidably connected to the surface of the storage box, and both ends of the limiting rods are fixedly connected to the crushing box.

[0017] The effect achieved by the above components is that the storage box slides along the arc surface of the limiting rod, and the limiting rod limits the moving path of the storage box.

[0018] Preferably, the inner wall of the rectangular frame is slidably connected with a perforated plate, the filter plate is fixedly mounted on the upper surface of the perforated plate, the filter plate is made of activated carbon, the air pump is fixedly mounted on the outer wall of the crushing box, the air inlet end of the air pump is fixed and connected with a connecting pipe, the connecting pipe passes through the crushing box, and the crushing box is fixed and connected to the rectangular frame.

[0019] The effect achieved by the above components is: the air pump is started intermittently. When the air pump is working, the connecting pipe will suck the air in the rectangular frame, and a negative pressure will be formed in the rectangular frame. The orifice plate will slide down along the inner wall of the rectangular frame, and the air in the crushing box will flow through the filter plate and the orifice plate into the rectangular frame. The flowing air will drive the powdered raw materials to pass through the screening plate quickly, thereby improving the screening efficiency of the screening plate, and preventing the powdered raw materials from sliding into the storage box and occupying the internal space of the storage box as much as possible, improving the space utilization efficiency of the storage box, and reducing the workload of the crushing roller during subsequent secondary crushing. During this process, the filter plate made of activated carbon will filter the powdered raw materials in the air to prevent the powdered raw materials from entering the rectangular frame and accumulating.

[0020] Preferably, two first springs are fixedly connected to the inner wall of the rectangular frame, and one end of the first spring is fixedly connected to the orifice plate.

[0021] The effect achieved by the above components is: when the air pump is turned off, the negative pressure in the rectangular frame disappears, the first spring begins to stretch, and the orifice plate drives the filter plate to slide upward with the help of the tension of the first spring. Therefore, continuously opening and closing the air pump can make the filter plate vibrate continuously, thereby causing the powdered raw materials attached to the surface of the filter plate to fall off, and trying to prevent the filter plate from being blocked.

[0022] Preferably, the exhaust end of the air pump is fixed and connected to two exhaust pipes, the arc surface of the exhaust pipe is fixed and connected to a plurality of nozzles, the nozzles are located above the storage box, and the lower ends of the nozzles are pointed structures.

[0023] The effect achieved by the above components is: when the air pump is turned on, high-speed air will flow into the exhaust pipe through the exhaust end of the air pump, and then the air will be discharged by the nozzle. At this time, the air will blow the raw material particles in the storage box, accelerating the sliding speed of the raw material particles, thereby improving the utilization efficiency of the air pump.

[0024] Preferably, one end of the two telescopic rods away from the sliding block is fixedly connected to a hollow plate, the two ends of the hose are respectively fixed and connected to the hollow plate and the exhaust pipe, the hose passes through the crushing box, and the hollow plate is fixed and connected to the circular tube.

[0025] The effect achieved by the above components is: in the process of the sliding block moving along the arc surface of the bidirectional screw, when the air pump is started, air will flow from the connecting pipe into the hose, and then the air will flow through the hollow plate and be discharged by the circular tube. The air will blow away the powdered raw materials attached to the arc surface of the bidirectional screw, and try to prevent the powdered raw materials from hindering the movement of the sliding block along the arc surface of the bidirectional screw, thereby improving the stability of the bidirectional screw during operation.

[0026] Preferably, a plurality of bristles are fixedly connected to one end of the circular tube away from the hollow plate, and a second spring is fixedly connected between the hollow plate and the sliding block.

[0027] The effect achieved by the above components is: the movement of the hollow plate with the help of the telescopic rod will drive the bristles to slide along the arc surface of the bidirectional screw rod, and the bristles will brush the arc surface of the bidirectional screw rod, thereby improving the cleaning efficiency of the powdered raw materials.

[0028] Preferably, the processing technology of vacuum bag film includes the following processing steps:

[0029] S1. Install the appropriate screen plate into the crushing box according to the required vacuum bag film raw material particle size;

[0030] S2. Pour the vacuum bag film raw material particles into the crushing box, use two crushing rollers to perform preliminary crushing on the vacuum bag film raw material particles, and at the same time, the screening plate will screen the raw material particles. The larger raw material particles will slide into the storage box. The air in the crushing box is sucked by the air pump to speed up the speed of the powdered raw material passing through the screening plate, thereby improving the screening efficiency of the screening plate;

[0031] S3. Use the second motor and other components to drive the storage box to move upward and pour out the raw material particles to achieve the purpose of secondary crushing of the raw material particles. During the movement of the storage box, the gas discharged by the air pump and the bristles are used to clean the powdery foreign matter attached to the arc surface of the bidirectional screw rod to ensure that the sliding block can move normally along the arc surface of the bidirectional screw rod.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] 1. The present invention sets up a complex crushing structure and uses a screening plate to screen the raw material particles. The raw material particles of qualified volume will fall through the screening plate, while the raw material particles of larger volume will slide into the storage box. The storage box is made to reciprocate in the vertical direction with the help of a bidirectional screw rod. When the storage box slides to a certain position, the raw material particles will be poured out, and the raw material particles will be crushed for the second time by the crushing roller, thereby ensuring that the raw material particles can be evenly melted, which is convenient for the subsequent production of vacuum bag film.

[0034] 2. The present invention sets an auxiliary structure, uses an air pump to suck the air in the crushing box, and uses the air to drive the powdered air to pass through the screening plate quickly, thereby improving the screening efficiency of the screening plate and preventing the powdered raw materials from sliding into the storage box and occupying the internal space of the storage box as much as possible, thereby improving the space utilization efficiency of the storage box.

[0035] 3. The present invention provides a cleaning structure. When the air pump is started, air will flow through the hollow plate and be discharged from the circular tube during the movement of the sliding block along the circular surface of the bidirectional screw. The air will sweep away the powdered raw materials attached to the circular surface of the bidirectional screw, and try to prevent the powdered raw materials from interfering with the movement of the sliding block along the circular surface of the bidirectional screw, thereby improving the stability of the bidirectional screw during operation.

[0049] The specific settings and functions of the complex crushing structure 4, auxiliary structure 5 and cleaning structure 6 are described in detail below.

[0050] like Figure 2-7 and Figure 10As shown, the vertical cross-section of the screening plate 401 is in the shape of a "human", and two second motors 402 are fixedly connected to the upper surface of the crushing box 1. The output end of the second motor 402 is fixedly connected to the bidirectional screw rod 403, and the sliding block 404 is threadedly connected to the bidirectional screw rod 403. A U-shaped hole 405 is provided on the surface of the sliding block 404, and a U-shaped plate 406 is slidably connected to the inner wall of the U-shaped hole 405. The U-shaped plate 406 is fixedly connected to the storage box 407. The bottom of the inner wall of the storage box 407 is an inclined surface, and the inner wall of the storage box 407 is fixedly connected to the first elastic sheet 408. The position of the crushing box 1 relative to the storage box 407 is fixedly connected to two supporting plates 409. The supporting plates 409 are located below the storage box 407. The position of the crushing box 1 relative to the screening plate 401 rotates. There are two rotating plates 410 that are dynamically connected. The lower surface of the rotating plate 410 is fixedly connected with a bending plate 411. The bending plate 411 is slidably connected to the storage box 407. The inner wall of the crushing box 1 is tilted and fixedly connected with two guide plates 415. The upper surface of the guide plate 415 is fixedly connected with a number of L-shaped plates 416. The guide plate 415 is located above the crushing roller 2. When it is necessary to crush the vacuum bag film raw material particles, the appropriate screening plate 401 is installed in the crushing box 1 according to the required raw material particle size, and the vacuum bag film raw material particles are poured into the crushing box 1. Then, the output ends of the two first motors 3 are controlled to rotate in opposite directions. The rotation of the output end of the first motor 3 will drive the crushing roller 2 to rotate. At this time, the two crushing rollers 2 will squeeze the vacuum bag film raw material particles, The membrane raw material particles are crushed, and then the crushed vacuum bag membrane raw material particles will fall onto the surface of the screening plate 401. Since the vertical section of the screening plate 401 is in the shape of a "human", the crushed raw material particles will slide along the surface of the screening plate 401. At this time, the screening plate 401 will screen the raw material particles, and the raw material particles with qualified volume will fall through the screening plate 401, while the raw material particles with larger volume will continue to slide along the surface of the screening plate 401. Then the raw material particles with larger volume will slide to the surface of the rotating plate 410 and fall into the storage box 407. The storage box 407 will store the raw material particles with larger volume, and then start the second motor 402. The rotation of the output end of the second motor 402 will drive the bidirectional screw 403 to rotate, and the bidirectional screw The rod 403 drives the sliding block 404 to move upward with the help of the thread, and the movement of the U-shaped plate 406 with the help of the sliding block 404 drives the storage box 407 to move synchronously. The storage box 407 continues to move, causing the first elastic piece 408 to contact the lower surface of the long arm of the L-shaped plate 416. At this time, the long arm of the L-shaped plate 416 will squeeze the first elastic piece 408, and the first elastic piece 408 will stretch along the surface of the L-shaped plate 416 until one end of the first elastic piece 408 extends above the guide plate 415. Since the bottom of the inner wall of the storage box 407 is an inclined surface, the raw material particles will slide along the inner wall of the storage box 407 to the surface of the first elastic piece 408, and then the raw material particles will fall onto the surface of the guide plate 415 and slide along the guide plate 415 to between the two crushing rollers 2.The raw material particles are crushed for the second time using the crushing roller 2. The crushing box 1 is fixedly connected to a rectangular plate 412 relative to the rotating plate 410. A second elastic piece 413 is fixedly connected between the rectangular plate 412 and the rotating plate 410. During the movement of the storage box 407, the second elastic piece 413 gradually stretches, and the rotating plate 410 rotates upward. At this time, the rotating plate 410 will block the raw material particles sliding along the surface of the screening plate 401, and try to prevent the larger raw material particles from falling directly from the surface of the rotating plate 410 without secondary crushing. The second elastic piece 413 achieves the effect of automatically resetting the rotating plate 410. The inner wall of the crushing box 1 is provided with a blocking piece 417, and the blocking piece 417 includes two ends fixedly connected to the crushing box 1. The support rod 4171 is connected to the support rod 4171. A blocking plate 4172 slides through the support rod 4171. The surface of the blocking plate 4172 is provided with a groove 4173. The inner wall of the groove 4173 is slidably connected to an adjustment plate 4174. The surface of the blocking plate 4172 is threaded with a bolt 4175. The bolt 4175 passes through the blocking plate 4172 and abuts the surface of the adjustment plate 4174. The vertical cross-section of the upper end of the blocking plate 4172 is an obtuse triangle. The blocking member 417 cooperates with the rotating plate 410 to block the raw material particles sliding along the surface of the screening plate 401, and minimizes the occurrence of large raw material particles falling directly from the surface of the rotating plate 410 without secondary crushing. The surface of the storage box 407 is slidably connected to two limit rods 414. Both ends of the limit rods 414 are fixedly connected to the crushing box 1. The storage box 407 slides along the arc surface of the limit rods 414, and the limit rods 414 serve to limit the movement path of the storage box 407. ,

[0051] like Figure 8 and Figure 9As shown, the inner wall of the rectangular frame 51 is slidably connected with a perforated plate 54, and a filter plate 55 is fixedly installed on the upper surface of the perforated plate 54. The filter plate 55 is made of activated carbon. The air pump 52 is fixedly installed on the outer wall of the crushing box 1. The air inlet end of the air pump 52 is fixed and connected with a connecting pipe 53. The connecting pipe 53 passes through the crushing box 1. The crushing box 1 is fixed and connected to the rectangular frame 51. The air pump 52 is started intermittently. When the air pump 52 is working, the connecting pipe 53 will suck the air in the rectangular frame 51, and a negative pressure will be formed in the rectangular frame 51. The perforated plate 54 will slide downward along the inner wall of the rectangular frame 51, and the air in the crushing box 1 will flow out. After passing through the filter plate 55 and the orifice plate 54 and entering the rectangular frame 51, the flowing air will drive the powdered raw materials to quickly pass through the screening plate 401, thereby improving the screening efficiency of the screening plate 401, and preventing the powdered raw materials from sliding into the storage box 407 and occupying the internal space of the storage box 407, thereby improving the space utilization efficiency of the storage box 407 and reducing the workload of the crushing roller 2 during subsequent secondary crushing. During this process, the filter plate 55 made of activated carbon will filter the powdered raw materials in the air and try to prevent the powdered raw materials from entering the rectangular frame 51 and accumulating. Two first springs 56 are fixedly connected to the inner wall of the rectangular frame 51, and one end of the first spring 56 is fixedly connected to the orifice plate 54. When the air pump 52 is turned off, the negative pressure in the rectangular frame 51 disappears, and the first spring 56 begins to stretch. The orifice plate 54 drives the filter plate 55 to slide upward with the help of the tension of the first spring 56. Therefore, continuously opening and closing the air pump 52 can make the filter plate 55 vibrate continuously, so that the powdered raw material attached to the surface of the filter plate 55 falls off, and the filter plate 55 is prevented from being blocked as much as possible. The exhaust end of the air pump 52 is fixed and connected to two exhaust pipes 57. The arc surface of the exhaust pipe 57 is fixed and connected to several nozzles 58. The nozzle 58 is located above the storage box 407. The lower end of the nozzle 58 is a pointed structure. When the air pump 52 is turned on, high-speed air will flow into the exhaust pipe 57 through the exhaust end of the air pump 52, and then the air will be discharged by the nozzle 58. At this time, the air will blow the raw material particles in the storage box 407, accelerate the sliding speed of the raw material particles, thereby improving the utilization efficiency of the air pump 52.

[0052] like Figure 3 and Figure 4As shown, one end of the two telescopic rods 61 away from the sliding block 404 is fixedly connected to the hollow plate 62, and the two ends of the hose 63 are respectively fixed and connected to the hollow plate 62 and the exhaust pipe 57. The hose 63 runs through the crushing box 1, and the hollow plate 62 is fixed and connected to the circular tube 64. In the process of the sliding block 404 moving along the arc surface of the bidirectional screw rod 403, when the air pump 52 is started, air will flow from the connecting pipe 53 into the hose 63, and then the air will flow through the hollow plate 62 and be discharged by the circular tube 64. The air will sweep the powdered raw materials attached to the arc surface of the bidirectional screw rod 403, and try to prevent the powdered raw materials from hindering the sliding block 404 from moving along the arc surface of the bidirectional screw rod 403, thereby improving the stability of the bidirectional screw rod 403 during operation. A plurality of bristles 65 are fixedly connected to one end of the circular tube 64 away from the hollow plate 62, and a second spring 66 is fixedly connected between the hollow plate 62 and the sliding block 404. The movement of the hollow plate 62 with the help of the telescopic rod 61 will drive the bristles 65 to slide along the arc surface of the bidirectional screw rod 403. The bristles 65 will brush the arc surface of the bidirectional screw rod 403, thereby improving the cleaning efficiency of the powdered raw materials.

[0053] like Figure 1-9 As shown, the processing technology of vacuum bag film includes the following processing steps:

[0054] S1. Install the appropriate screening plate 401 into the crushing box 1 according to the required vacuum bag film raw material particle size;

[0055] S2. Pour the vacuum bag film raw material particles into the crushing box 1. Use two crushing rollers 2 to perform preliminary crushing on the vacuum bag film raw material particles. At the same time, the screening plate 401 will screen the raw material particles. The larger raw material particles will slide into the storage box 407. The air in the crushing box 1 is sucked by the air pump 52 to accelerate the speed of the powdered raw material passing through the screening plate 401, thereby improving the screening efficiency of the screening plate 401.

[0056] S3. Use the second motor 402 and other components to drive the storage box 407 to move upward and pour out the raw material particles, so as to achieve the purpose of secondary crushing of the raw material particles. During the movement of the storage box 407, the gas discharged by the air pump 52 and the brush 65 are used to clean the powdery foreign matter attached to the arc surface of the bidirectional screw rod 403, ensuring that the sliding block 404 can move normally along the arc surface of the bidirectional screw rod 403.

[0057] Working principle: When the vacuum bag film raw material particles need to be crushed, the appropriate screening plate 401 is installed in the crushing box 1 according to the required raw material particle size, the vacuum bag film raw material particles are poured into the crushing box 1, and then the output ends of the two first motors 3 are controlled to rotate in opposite directions. The rotation of the output end of the first motor 3 will drive the crushing roller 2 to rotate. At this time, the two crushing rollers 2 will squeeze the vacuum bag film raw material particles and crush the vacuum bag film raw material particles. Then, the crushed vacuum bag film raw material particles will fall onto the surface of the screening plate 401. Since the vertical cross-section of the screening plate 401 is in the shape of a "human", the crushed raw material particles will slide along the surface of the screening plate 401. At this time, the screening plate 401 will screen the raw material particles, and the raw material particles with qualified volume will pass The particles passing through the screening plate 401 will fall, while the larger raw material particles will continue to slide along the surface of the screening plate 401. Then the air pump 52 will be started intermittently. When the air pump 52 is working, the connecting pipe 53 will suck the air in the rectangular frame 51, and a negative pressure will be formed in the rectangular frame 51. The orifice plate 54 will slide downward along the inner wall of the rectangular frame 51. The sliding of the orifice plate 54 will squeeze the first spring 56. At this time, the first spring 56 is in a compressed state, and the air in the crushing box 1 will flow through the filter plate 55 and the orifice plate 54 into the rectangular frame 51. The flowing air will drive the powdered raw material to pass through the screening plate 401 quickly, thereby improving the screening efficiency of the screening plate 401 and preventing the powdered raw material from sliding into the storage box 407 and occupying the internal space of the storage box 407 as much as possible. The space utilization efficiency of the storage box 407 is improved, and the workload of the crushing roller 2 during subsequent secondary crushing is reduced. During this process, the filter plate 55 made of activated carbon will filter the powdered raw materials in the air, and try to prevent the powdered raw materials from entering the rectangular frame 51 and accumulating. When the air pump 52 is turned off, the negative pressure in the rectangular frame 51 disappears. At this time, the first spring 56 begins to stretch, and the orifice plate 54 drives the filter plate 55 to slide upward with the help of the tension of the first spring 56. Therefore, continuously opening and closing the air pump 52 can make the filter plate 55 vibrate continuously, so that the powdered raw materials attached to the surface of the filter plate 55 fall off, and try to prevent the filter plate 55 from being blocked. Then, the larger raw material particles will slide to the rotating plate 410 The raw material particles are stored in the storage box 407. During this process, the gap between the adjusting plate 4174 and the rotating plate 410 can limit the speed at which the raw material particles slide into the storage box 407, and try to prevent a large number of raw material particles from sliding into the storage box 407 at the same time and causing the raw material particles to spill. When the falling speed of the raw material particles needs to be adjusted, the adjusting plate 4174 is slid along the inner wall of the groove 4173. The adjusting plate 4174 changes the gap between it and the rotating plate 410, thereby adjusting the speed at which the raw material particles pass between the adjusting plate 4174 and the rotating plate 410. After the adjustment is completed, the bolt 4175 is turned, and the bolt 4175 moves with the help of the thread and rests on the surface of the adjusting plate 4174.The bolt 4175 reaches the function of limiting the position of the adjustment plate 4174, and then the second motor 402 is started. The rotation of the output end of the second motor 402 will drive the bidirectional screw 403 to rotate, and the bidirectional screw 403 will drive the sliding block 404 to move upward with the help of the thread. The U-shaped plate 406 moves with the help of the sliding block 404 to drive the storage box 407 to move synchronously. During the movement of the storage box 407, the second elastic piece 413 gradually stretches, and the rotating plate 410 will rotate upward. The rotating plate 410 will contact the adjusting plate 4174 when it rotates. At this time, the rotating plate 410 will squeeze the adjusting plate 4174, and the adjusting plate 4174 will drive the blocking plate 4172 to slide along the support rod 4171. The blocking plate 4172 slides and contacts the arc surface of the crushing roller 2. 2, the vertical cross-section of the upper end is an obtuse triangle, so the upper end of the blocking plate 4172 can easily scrape the raw materials attached to the surface of the crushing roller 2 to ensure that the crushing roller 2 can work normally. At this time, the rotating plate 410 cooperates with the blocking plate 4172 and the adjusting plate 4174 to block the raw material particles sliding along the surface of the screening plate 401, and try to prevent the larger raw material particles from falling directly from the surface of the rotating plate 410 without secondary crushing. During this process, the storage box 407 will slide along the arc surface of the limiting rod 414, and the limiting rod 414 has the effect of limiting the moving path of the storage box 407. The storage box 407 continues to move, which will cause the first elastic piece 408 to contact the lower surface of the long arm of the L-shaped plate 416. At this time, the long arm of the L-shaped plate 416 will squeeze The first elastic sheet 408 is pressed, and the first elastic sheet 408 stretches along the surface of the L-shaped plate 416 until one end of the first elastic sheet 408 extends to the top of the guide plate 415, and the nozzle 58 is inserted into the raw material particles in the storage box 407. Since the bottom of the inner wall of the storage box 407 is an inclined surface, the raw material particles slide along the inner wall of the storage box 407 to the surface of the first elastic sheet 408. When the air pump 52 is turned on, high-speed air flows into the exhaust pipe 57 through the exhaust end of the air pump 52, and then the air is discharged by the nozzle 58. At this time, the air blows the raw material particles in the storage box 407, speeding up the sliding speed of the raw material particles, thereby improving the utilization efficiency of the air pump 52. After that, the raw material particles fall to the surface of the guide plate 415 and slide along the guide plate 415 slides between the two crushing rollers 2, and the crushing rollers 2 are used to perform secondary crushing on the raw material particles. When the second motor 402 continues to rotate, the sliding block 404 moves downward along the arc surface of the bidirectional screw rod 403. At this time, the storage box 407 will slide downward synchronously under the influence of its own gravity, and then the storage box 407 will contact the bending plate 411. The storage box 407 will squeeze the bending plate 411, and the bending plate 411 will drive the rotating plate 410 to rotate downward. The rotation of the rotating plate 410 will squeeze the second elastic sheet 413, so that the second elastic sheet 413 is in a compressed state, and the blocking plate 4172 will slide downward under the influence of its own gravity. At this time, the obtuse triangle structure at the upper end of the blocking plate 4172 can prevent the blocking plate 4172 from falling out of the support rod 4171 as much as possible.When the storage box 407 contacts the supporting plate 409, the supporting plate 409 will prevent the storage box 407 from sliding further downward, thereby limiting the position of the storage box 407. At the same time, the rotating plate 410 is in a tilted downward state, and the raw material particles will continue to slide along the surface of the rotating plate 410 into the storage box 407. During this process, the bidirectional screw rod 403 will continue to drive the sliding block 404 to slide downward. Since the surface of the sliding block 404 is provided with a U-shaped hole 405, the sliding block 404 can still continue to move downward a certain distance when the U-shaped plate 406 does not move. During the sliding process of the sliding block 404, the raw material particles have enough time to slide into the storage box 407, thereby improving the storage efficiency of the storage box 407. The continued rotation of the bidirectional screw rod 403 will cause the sliding block 404 to move upward, thereby achieving the purpose of making the storage box 407 reciprocate in the vertical direction without changing the rotation direction of the output end of the second motor 402, thereby continuously performing secondary crushing on the larger raw material particles.

[0058] When the sliding block 404 moves along the arc surface of the bidirectional screw rod 403, when the air pump 52 is started, air will flow from the connecting pipe 53 into the hose 63, and then the air will flow through the hollow plate 62 and be discharged by the circular tube 64. The air will sweep the powdered raw materials attached to the arc surface of the bidirectional screw rod 403, and try to prevent the powdered raw materials from hindering the sliding block 404 from moving along the arc surface of the bidirectional screw rod 403, thereby improving the stability of the bidirectional screw rod 403 when working. The movement of the sliding block 404 will drive the telescopic rod 61 to move, and the hollow plate 62 will move with the help of the telescopic rod 6 The movement of 1 will drive the bristles 65 to slide along the arc surface of the bidirectional screw rod 403, and the bristles 65 will brush the arc surface of the bidirectional screw rod 403, thereby improving the cleaning efficiency of the powdered raw materials. During this process, the second spring 66 will continue to contract, and the hollow plate 62 will slide toward the sliding block 404. The telescopic rod 61 can limit the sliding path of the hollow plate 62. The circular tube 64 slides with the help of the hollow plate 62, which will cause the bristles 65 to tightly press against the arc surface of the bidirectional screw rod 403, thereby improving the cleaning effect of the bristles 65 on the powdered raw materials.
