The particle size after crushing is large, which easily causes the filter to be blocked. The main crushing knife and the auxiliary crushing knife cooperate with each other to achieve further crushing and refinement of the injection molded parts to avoid the filter being blocked. However, by reducing the particle size to avoid the filter being blocked, it is undoubtedly necessary to increase the fineness of the crushing work and reduce the feeding speed, which will greatly affect the crushing efficiency;

[0035] The power unit includes a cross bar 5, an electric actuator 6 and a top plate 7; the crushing box 1 is welded with the cross bar 5; two electric actuators 6 distributed front and back are installed on each cross bar 5; the electric actuator 6 is an electric push rod; the telescopic parts of all electric actuators 6 are fixedly connected to the top plate 7; the movable end of the screen plate 2 is in contact with the top plate 7.

[0036] It also includes guide blocks I8 and guide blocks II9; multiple guide blocks I8 are fixedly connected to the side wall of the crushing box 1; gaps are left between adjacent guide blocks I8; multiple guide blocks II9 are fixedly connected to the cross bar 5 on the side away from the electric actuator 6; each guide block II9 corresponds to a gap between adjacent guide blocks I8; two crushing rollers 3 are located between the guide blocks I8 and the guide blocks II9; all guide blocks I8 and corresponding guide blocks II9 form a V-shaped guide structure; each crushing unit is provided with a V-shaped guide structure.

[0037] It also includes a baffle 103; a dust removal chamber 1001 is opened in the right wall of the crushing box 1; a plurality of dust suction ports 1002 are opened on the right side of the crushing box 1; all the dust suction ports 1002 are connected to the dust removal chamber 1001; and the lower part of the dust removal chamber 1001 is connected to the baffle 103.

[0038] The working process of the above embodiment is as follows:

[0039] Fix the crushing box 1 through the frame, connect the crushing roller 3 and the cross rotating frame 10 to the external motor, connect the electric actuator 6 to the power supply; connect the baffle 103 to the air pump;

[0040] A plurality of crushing units are arranged in the crushing box 1. In this embodiment, a case where three crushing units are arranged in the crushing box 1 is described in detail;

[0041] First, multiple injection molded parts 001 are placed vertically together in the feed port of the crushing box 1, so that the lower part of the injection molded parts 001 contacts the inclined surface 1004, and then each injection molded part 001 slides down along the inclined surface 1004 in turn. Figure 3 As shown, the groove of the injection molded body 001 is upward. At this time, the description is based on the initial state that the groove of the injection molded body 001 is upward. Vice versa, the cross rotating frame 10 is then controlled to rotate. From the front to the back, the rotation direction of the cross rotating frame 10 is counterclockwise. The cross rotating frame 10 moves the suspended part of the injection molded body 001 that is not in contact with the inclined surface 1004, and the injection molded body 001 rotates around the turning part 1005. The lower part of the injection molded body 001 rotates to below the narrow neck of the crushing box 1, and the side of the injection molded body 001 that is not in contact with the cross rotating frame 10 contacts the left inner wall of the crushing box 1 during the rotation process.

[0042] Then the injection molded part body 001 falls on the sieve plate 2. At this time, the state of the injection molded part body 001 is that the groove is downward, and the two electric actuators 6 at the top are controlled to extend, and the top plate 7 is synchronously driven to move upward. The upper part of the top plate 7 contacts the movable end of the sieve plate 2. Therefore, when the top plate 7 moves upward, the movable end of the sieve plate 2 also moves upward, and the sieve plate 2 also drives the injection molded part body 001 thereon to move upward, and then the two electric actuators 6 at the top are controlled to contract, so that the movable end of the sieve plate 2 moves downward, and the sieve plate 2 also drives the injection molded part body 001 thereon to move downward, and the above process is repeated, so that the lower part of the sieve plate 2 swings back and forth, and the injection molded part body 001 is transferred downward along the sieve plate 2, and then the injection molded part body 001 falls between the two crushing rollers 3, and at the same time, the external motor drives the crushing rollers 3 to rotate. The two crushing rollers 3 rotate in opposite directions through the meshing gears 4. Looking from the front to the back, the crushing roller 3 on the left rotates clockwise, so that the two crushing rollers 3 perform preliminary crushing on the injection molded part body 001;

[0043] By arranging three crushing units in the crushing box 1 and arranging a V-shaped guide structure composed of guide blocks I8 and guide blocks II9 on both sides of the crushing unit, the injection molded part body 001 falling from the screen plate 2 is gathered between the two crushing rollers 3, thereby improving the crushing efficiency, so that the injection molded part body 001 that has completed the initial crushing falls downward onto the screen plate 2 of the lower crushing unit, and the transfer and crushing process of the injection molded part body 001 described above is repeated, the secondary crushing of the injection molded part body 001 is completed at the second crushing unit, and the tertiary crushing is completed at the third crushing unit, and finally the crushed injection molded part body 001 powder is discharged from the bottom of the crushing box 1, and a collection box is arranged under the crushing box 1 to collect the injection molded part body 001 powder.

[0044] A dust removal chamber 1001 is opened in the crushing box 1, and a baffle 103 is connected to the lower part of the dust removal chamber 1001. A dust suction port 1002 is opened in the dust removal chamber 1001 to connect with the inside of the crushing box 1. The baffle 103 is connected to an external air pump. Thus, the dust and debris generated during the crushing process of the injection molded part body 001 can be sucked into the dust removal chamber 1001 through the dust suction port 1002 by suctioning air through the external air pump.

[0045] According to the above working process, we know that the present invention has the following effects:

[0046] By rotating the cross rotating frame 10, the injection molded part body 001 on the inclined surface 1004 is moved to flip over. The side of the injection molded part body 001 that is not in contact with the cross rotating frame 10 hits the left wall of the crushing box 1 during the flipping process of the injection molded part body 001, and the crushed materials in the groove of the injection molded part body 001 are shaken out, thereby preliminarily realizing the separation of injection molded parts 001 of different sizes; and then the injection molded part body 001 is driven to shake through the sieve plate 2. In the process of moving the injection molded part body 001 downward, the crushed materials in the groove of the injection molded part body 001 are fully shaken out, thereby effectively realizing the full separation of the crushed materials and the injection molded part body 001.

[0047] By tilting the sieve plate 2 and shaking the lower part of the sieve plate 2, not only can the injection molded part body 001 be transferred, but also the crushed materials mixed in the groove of the injection molded part body 001 can be shaken out during the shaking of the sieve plate 2. The shaking also prevents the sieve plate 2 from being blocked by the injection molded part body 001. The crushed materials shaken out fall from the mesh gaps of the top sieve plate 2 and fall on the sieve plate 2 with smaller mesh gaps below, thereby reducing the crushed materials mixed in the injection molded part body 001 and crushing together, improving the crushing efficiency of the crushing roller 3, and the distance between the crushing rollers 3 from top to bottom is gradually shortened, which effectively makes the injection molded part bodies 001 of different sizes gradually crushed in different crushing units, so that the crushed particles of the injection molded part body 001 are uniform;

[0048] When the injection molded part body 001 that has completed the preliminary crushing falls down onto the screen plate 2 of the lower crushing unit, the second crushing unit first shakes and screens the particles of the injection molded part body 001 to effectively prevent the screen plate 2 from being blocked, and screens the small particles to the crushing unit below for processing, or directly discharges them, while the injection molded part body 001 with large particles is transferred to the crushing roller 3 of the second crushing unit for more refined crushing. When the crushed injection molded part body 001 is transferred to the third crushing unit, the above operation is repeated, and the crushed injection molded part 001 is screened and crushed more finely again. Thus, the injection molded part 001 is subjected to multi-stage crushing and multi-stage screening, which can not only increase the feeding speed, but also improve the crushing efficiency, and is highly practical.

[0049] By providing the dust suction port 1002, the dust generated in the crushing box 1 is sucked into the dust removal chamber 1001, which effectively reduces the dust from escaping and polluting the environment.

[0050] On the basis of the above technical effects, the present invention also has the following advantages:

[0051] First, a rolling curtain 11 is arranged between the adjacent guide blocks I8 and II9, and when the top plate 7 lifts up the movable end of the screen plate 2, the top plate 7 also pulls up the rolling curtain 11 between the guide blocks II9, and when the top plate 7 moves downward, the torsion spring at the central rotation axis of the rolling curtain 11 causes the rolling curtain 11 to be rolled up again, and the rolling curtain 11 always blocks the gap between the adjacent guide blocks II9, effectively preventing the injection molded part body 001 from entering the position between the guide block II9 and the crushing roller 3 when the injection molded part body 001 is shaken off, and the rolling curtain 11 with the torsion spring can also buffer the fallen fragments when the injection molded part body 001 is shaken off, thereby avoiding the later cleaning of the position between the guide blocks I8 and the guide blocks II9 and the crushing roller 3, and the impact damage of the fragments on the device, thereby reducing the maintenance cost.

[0052] Second, the dust suction port 1002 is an inverted V-shaped structure. The lower part of the dust suction port 1002 is on one side in the crushing box 1 and is inclined toward the crushing roller 3, which has a better suction effect on dust. The lower part of the dust suction port 1002 is on one side in the dust removal chamber 1001 and is inclined downward. Figure 5 As shown, it is effectively prevented that the crushed debris splashing upward directly passes through the dust suction port 1002 and enters the dust removal chamber 1001, thereby affecting the subsequent collection of dust.

[0053] Third, circulating water is injected into the central rotating shaft of the crushing roller 3 through the water pipe Ⅰ101. From the front to the back, the liquid level of the circulating water is two-fifths of the inner diameter of the central rotating shaft of the crushing roller 3. When the crushing roller 3 crushes the injection molded part body 001, the crushing roller 3 generates a lot of heat. The circulating water cools the crushing roller 3 to ensure the service life of the crushing roller 3.

[0054] Moreover, the heat generated by the crushing roller 3 causes part of the water in the central rotating shaft of the crushing roller 3 to evaporate. The space in the central rotating shaft of the crushing roller 3 is certain. When water vapor is generated, the central rotating shaft of the crushing roller 3 begins to exhaust outwards, and the water vapor enters the dust removal chamber 1001 through the steam pipe 102. The water vapor condenses on the side wall of the dust removal chamber 1001 to cool the crushing box 1. When the dust contacts the side wall of the dust removal chamber 1001, the water droplets are mixed with the dust in the dust removal chamber 1001, and then the water droplets slide down along the dust removal chamber 1001 with the dust, thereby realizing rapid dust reduction in the dust removal chamber 1001.

[0055] Second embodiment

[0056] On the basis of the first embodiment, according to Figure 1-5 and Figure 7-9 As shown, it also includes a pump 201, a main pipe 202, a branch pipe 203, a water pipe II 204 and a liquid collecting pipe 205; the pump 201 is installed at the front of the crushing box 1; the input end of the pump 201 is connected to the main pipe 202; the main pipe 202 is connected to multiple branch pipes 203; each branch pipe 203 is connected to the crushing roller 3 of each crushing unit; the output end of the pump 201 is connected to the water pipe II 204; the upper part of the crushing box 1 is opened with a guide cavity 1003; the water pipe II 204 runs through the front part of the guide cavity 1003; the rear part of the water pipe II 204 is located in the guide cavity 1003; the part of the water pipe II 204 located in the guide cavity 1003 is opened with a water spray port, and the water spray port is connected to the guide cavity 1003; the lower part of the baffle 103 is connected with the liquid collecting pipe 205.

[0057] The working process of the above embodiment is as follows:

[0058] Connect the pump 201 to a power source;

[0059] Connect the liquid collecting pipe 205 to the water circulation equipment;

[0060] The pump 201 is controlled to start. The pump 201 extracts the circulating water in the central shaft of the crushing roller 3 in each crushing unit through the main pipe 202 and each branch pipe 203. Then the pump 201 pumps the circulating water through the water pipe II 204 to the upper guide cavity 1003 of the crushing box 1. The circulating water flows along the guide cavity 1003. When the circulating water reaches the dust removal cavity 1001, it flows downward along the inner wall of the dust removal cavity 1001. At the same time, the dust suction port 1002 is an inverted V-shaped structure. , so that when the circulating water flows downward along the inner wall of the dust removal chamber 1001, it will not enter the crushing box 1 through the dust suction port 1002, and then when the circulating water flows to the bottom of the dust removal chamber 1001, the bottom of the dust removal chamber 1001 is connected with the baffle 103, and the circulating water enters the baffle 103, and then enters the liquid collecting pipe 205 connected with the baffle 103. The water circulation equipment draws out the water in the liquid collecting pipe 205, and after filtering the water, it is pumped back into the water pipe I101 to participate in the circulation.

[0061] According to the above working process, we know that the present invention has the following effects:

[0062] In the first embodiment, it is described that by pouring circulating water into the central rotating shaft of the crushing roller 3, the circulating water is always in the lower part of the cavity of the central rotating shaft of the crushing roller 3 during the rotation of the crushing roller 3, so the circulating water continuously cools the crushing roller 3, and after the circulating water is heated, the water vapor enters the dust removal chamber 1001 to participate in dust reduction, and the water vapor condenses on the inner wall of the dust removal chamber 1001. After the dust enters the dust removal chamber 1001, the dust combines with the water droplets. Before the water droplets gather enough water to flow downward, the dust and the water droplets are retained on the side wall of the dust removal chamber 1001. At this time, it is only necessary to control the pump 201 to extract the circulating water at the lower part of the central rotating shaft of the crushing roller 3, and then pump it out through the water pipe II 204. The circulating water flows in the guide chamber 1003, which can not only cool down the crushing box 1, but also after entering the dust removal chamber 1001 from the guide chamber 1003, the circulating water flows downward along the inner wall of the dust removal chamber 1001, and the circulating water flushes the inner wall of the dust removal chamber 1001, and flushes the dust and water droplets retained on the inner wall of the dust removal chamber 1001 downward, effectively avoiding leaving water stains with dust on the inner wall of the dust removal chamber 1001, and the inverted V-shaped dust suction port 1002 can also effectively prevent the circulating water from passing through the dust suction port 1002 and entering the crushing box 1, and finally the circulating water is collected in the collecting pipe 205, and the dusty water is pumped back to the water circulation equipment, and after the water purification is completed, it re-participates in the water circulation.

[0063] Furthermore, the dust suction port 1002 is an inverted V-shaped structure, so that when the circulating water flows downward along the inner wall of the dust removal chamber 1001, it will not enter the crushing box 1 through the dust suction port 1002, causing the parts in the crushing box 1 to become wet and dust to easily form on the parts in the crushing box 1.

[0064] According to the above working process, the present invention also has the following effects:

[0065] First, the guide cavity 1003 is arranged to be inclined, so that after the circulating water enters the guide cavity 1003 , it automatically flows downward along the guide cavity 1003 into the dust removal cavity 1001 .

[0066] Second, the baffle 103 is arranged in a V-shaped structure. When air is pumped out from the dust removal chamber 1001, the circulating water also flows in the dust removal chamber 1001. The right part of the baffle 103 is tilted, which effectively prevents the water from being pumped away by the air pump when the suction force of the air pump is large.

[0067] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
