Description

Technical Field

[0001] The invention belongs to the technical field of PVC calendering film waste recycling, in particular to a PVC film calendering machine waste recycling device. Background Art

[0002] PVC film calender is a kind of equipment used to produce PVC calendered film. In the production process of PVC calendered film, it is necessary to cut both sides of the PVC film, and the cut scraps can be collected and added to the feed port of the PVC film calender to achieve recycling;

[0003] In order to make the PVC film calender machine reuse the cut scraps, it is necessary to first crush the cut scraps and then add them to the feed port of the PVC film calender machine;

[0004] A patent application with publication number CN209955136U discloses a waste material processing device for a PVC calender, including an upper processing mechanism, a lower processing mechanism and a guide member, wherein the lower processing mechanism is provided below the upper processing mechanism, and the upper processing mechanism includes an upper guide bucket, an upper processing box and a stirring member, and the upper and lower ends of the upper guide bucket are both open, and the lower end opening thereof is connected to the inlet on the top wall of the upper processing box. The beneficial effects of the utility model are as follows: the upper processing mechanism and the lower processing mechanism are provided to fully crush the scraps and realize the recycling of the scraps; and the guide member provided at the same time can adjust the distance of the connecting rod extending into the sleeve according to the distance between the lower processing chamber and the feed port of the PVC film calender.

[0005] However, the above technical solution still has the following deficiencies in practical application:

[0006] When the scraps need to be crushed, they are added into the processing box through the upper guide bucket, and the scraps are made to fall under the action of gravity and contact the stirring blades. However, since there are gaps between the multiple stirring blades and between the stirring blades and the processing box, some of the scraps may fall through these gaps, forming a crushing dead angle, resulting in incomplete crushing of the scraps and affecting subsequent reuse; and some existing crushing mechanisms place the scraps inside the crushing barrel and use the rotation of the blade to continuously crush them, but the scraps accumulated at the bottom of the crushing barrel still cannot be crushed.

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0035] Embodiment 1

[0036] like Figure 1-9As shown, a PVC film calender waste recycling device described in an embodiment of the present invention includes a base 1, a support column 3 39 is fixedly connected to one side of the upper end surface of the base 1, a processing box 34 is fixedly connected to the top of the support column 39, crushing blades 40 are rotatably arranged on both sides of the processing box 34 through a rotating shaft, support columns 2 10 are fixedly connected to both sides of the upper end surface of the base 1, a material receiving frame 11 is rotatably arranged on the upper end of the support column 2 10 through a rotating shaft, a baffle 1 12 is slidably connected to one end of the material receiving frame 11, a baffle 2 13 is rotatably arranged on one end of the material receiving frame 11, and a circulating shoveling mechanism for continuously adding scraps to the processing box 34 is arranged on the upper end of the base 1;

[0037] The circulating shoveling mechanism includes a support column 2 fixedly connected to both sides of the base 1, the upper end of the support column 2 is fixedly connected to a mounting plate 3, one end of the right side of the mounting plate 3 is fixedly connected to two sliding rods 20, both sliding rods 20 are slidably connected to a slider 21, one side of the left end face of the slider 21 is fixedly connected to two sliding rods 22, the two sliding rods 22 are slidably connected to a slider 23, one end of the slider 23 is rotatably provided with a groove plate 24, the groove plate 24 is slidably connected to a slider 3 27 using the groove, and the front end of the slider 3 27 is fixedly connected to a shoveling frame 16.

[0038] Specifically, the PVC film calender is a device for producing PVC calendered film. In the production process of the PVC calendered film, it is necessary to cut the two sides of the PVC film before winding, which will inevitably produce a large amount of scraps. After these scraps are crushed, they can be directly fed into the feed part of the PVC film calender to achieve reuse. Therefore, it is necessary to use waste recycling equipment to crush the scraps generated in the production process of the PVC calendered film. When the existing waste recycling equipment for the PVC film calender is used, the scraps are usually put into the crushing box through the feed hopper and crushed by the crushing blade. However, since the crushing blade is in a continuous rotation state and there are gaps between the blades, it is inevitable that the scraps will have a crushing dead angle during the falling process, resulting in some scraps not being completely crushed, affecting the effect of the subsequent reuse of the scraps.

[0039] When using this embodiment, first move the base 1 to a position where the right end of the material receiving frame 11 is aligned with the feed inlet of the PVC film calender. If it is difficult to align the right end of the material receiving frame 11 with the feed inlet of the PVC film calender, a collection container can also be placed below the right side of the material receiving frame 11 to collect the scraps first, and then pour the scraps into the feed inlet of the PVC film calender by manual handling;

[0040] Then, the crushing blades 40 on both sides are driven to rotate in different directions at the same time, and the scraps of the PVC film are added to the processing box 34. The scraps can be cut and crushed for the first time by the rotation of the crushing blades 40. After the first crushing, the scraps will fall to the upper end of the receiving frame 11. At this time, the scraps at the upper end of the receiving frame 11 may not be completely crushed, so the shoveling frame 16 can be driven to start moving;

[0041] The shovel frame 16 moves under the cooperation of the slider 1 21 and the slider 2 23. The initial position of the slider 1 21 is at the uppermost end of the slide bar 1 20, and the initial position of the slider 23 is at the rightmost end of the slide bar 22. Then, the slider 1 21 is first moved downward on the slide bar 1 20 to move the shovel frame 16 downward until the bottom of the shovel frame 16 is in contact with the inner bottom of the material receiving frame 11, and the front and rear ends of the shovel frame 16 are also in contact with the side walls of the material receiving frame 11. Then, the baffle 12 is driven to move downward so that the upper end surface of the baffle 12 is flush with the bottom of the material receiving frame 11. The function of the baffle 12 is to prevent the scraps from falling into the right end of the material receiving frame 11, resulting in the situation where the bottom of the shovel frame 16 presses the scraps. Then, the slider 2 23 is driven to slide on the slide bar 22 The shovel frame 16 is moved to move from right to left, and the scraps are shoveled into the shovel frame 16 by using the shovel frame 16 until the shovel frame 16 abuts against the inner wall of the left end of the receiving frame 11, and then the shovel frame 16 and the shovel frame 16 are driven to move, first returning the shovel frame 16 to the initial position, and then moving the shovel frame 16 to the left, so that the shovel frame 16 comes to the top of the processing box 34, and then the groove plate 24 is driven to rotate counterclockwise, so that the shovel frame 16 can be tilted, so that the scraps fall into the processing box 34 again, and are crushed for the second time under the rotation of the crushing blade 40. The scraps that have been crushed for the second time fall into the receiving frame 11 again, and then the above-mentioned shovel operation is repeated multiple times, so that the scraps can be crushed multiple times, which can reduce the crushing dead angle to a large extent and achieve a better crushing effect;

[0042] After the crushing work is completed, the material receiving frame 11 can be driven to rotate clockwise to tilt the material receiving frame 11, so that the scraps can slide to the left end of the baffle 2 13 under the action of gravity, and then the baffle 2 13 can be driven to rotate counterclockwise to form an opening with the right end of the baffle 2 13 and the material receiving frame 11. The crushed scraps can fall into the feed port of the PVC film calender or the collection container, so that the recycling of the scraps is realized.

[0043] like Figure 1 , Figure 2 , Figure 5As shown, a motor 5 31 is fixedly connected to one side of the rear end face of the mounting plate 3, a plurality of sprockets 5 are rotatably provided on the front end face of the mounting plate 3, the sprockets 5 are meshingly connected with a chain 4, the output end of the motor 5 31 is fixedly connected to the sprocket 5 via a rotating shaft, one end of the chain 4 is rotatably connected to the slider 2 23 via a rotating shaft, the front end face of the mounting plate 3 is fixedly connected to the shell 2 42, the connection between the chain 1 4 and the slider 23 is embedded in the slide groove of the shell 2 42 by a rotating shaft and is slidably connected thereto.

[0044] Specifically, the motor 5 31 is used to drive the sprocket 5 to rotate, so that the chain 4 can start to move. The chain 4 uses the rotating shaft to drive the slider 23 to move. The rotating shaft at the connection between the chain 4 and the slider 23 slides along the slide groove of the shell 2 42. Since the slider 23 slides on the slide bar 22 and the slider 21 slides on the slide bar 20, the slider 23 can continue to move with the chain 4 and always remain vertical without deflection, so that the shovel frame 16 can move up and down and left and right to shovel up the scraps.

[0045] like Figure 1 , Figure 2 , Figure 7 As shown, the front end of the shovel frame 16 is fixedly connected to the shell three 43, both ends of the shovel frame 16 are embedded with driving rollers 19 through grooves and are rotatably connected thereto through a rotating shaft, one side of the front end surface of the shovel frame 16 is fixedly connected to a motor three 28, the rear output end of the motor three 28 is fixedly connected to the driving roller 19 through a rotating shaft, the front output end of the motor three 28 is fixedly connected to a sprocket two 17, the connection between the left driving roller 19 and the shovel frame 16 is fixedly connected to the sprocket two 17 through a rotating shaft, and a chain two 18 is meshed and connected between the two sprockets two 17.

[0046] Specifically, when the shovel frame 16 scoops up the scraps, the scraps will be at the left end of the shovel frame 16, and the motor three 28 can be used to drive the sprocket two 17 on the right side to rotate clockwise, that is, the sprocket two 17 on the left side can be rotated clockwise under the action of the chain two 18, so that the shifting rollers 19 on both sides rotate clockwise at the same time. When the shifting roller 19 rotates clockwise, the scraps on the left side of the shovel frame 16 will be shifted to the right, and the scraps will move to the right side inside the shovel frame 16. This can avoid the scraps falling off during the shoveling process because the scraps are concentrated on the left side of the shoveling frame 16, thereby increasing the number of scraps shoveled by the shovel frame 16 at one time and improving the effect of cyclic crushing.

[0047] like Figure 4 As shown, a hydraulic cylinder 30 is fixedly connected to one side of the lower end surface of the material receiving frame 11, and the piston end of the hydraulic cylinder 30 is fixedly connected to the baffle 12.

[0048] Specifically, when the scraps are being crushed, the upper end of the baffle 12 is higher than the upper end surface of the receiving frame 11. At this time, the scraps falling to the upper end of the receiving frame 11 will be blocked by the baffle 12, so that the scraps will not be on the right side of the baffle 12. When the shovel frame 16 starts to descend, the baffle 12 is lowered under the action of the hydraulic cylinder 30 until the top of the baffle 12 is flush with the bottom of the receiving frame 11. At this time, the scraps will not fall through the groove at the connection between the baffle 12 and the receiving frame 11, and the shovel frame 16 can also slide to the left, and the bottom of the shovel frame 16 will not press on the scraps.

[0049] like Figure 4 As shown, a motor 4 29 is fixedly connected to one side of the front end face of the support column 2 10, and the output end of the motor 4 29 is fixedly connected to the material receiving frame 11 through a rotating shaft. A motor 4 29 is fixedly connected to one side of the front end face of the material receiving frame 11, and the output end of the motor 4 29 is fixedly connected to the baffle 2 13 through a rotating shaft.

[0050] Specifically, after the scraps are crushed for multiple times, they can be put into the feeding part of the PVC film calender for reuse. Therefore, the hydraulic cylinder 30 can be started to drive the baffle 12 to descend, so that the upper end of the baffle 12 is flush with the bottom of the receiving frame 11, and then the motor 4 29 is started to drive the receiving frame 11 to rotate clockwise, so that the receiving frame 11 is tilted. At this time, the crushed scraps slide to the right end of the receiving frame 11 under the action of gravity and abut against the left end face of the baffle 2 13. Then the motor 14 is started to drive the baffle 2 13 to rotate counterclockwise, so that the baffle 2 13 and the right end of the receiving frame 11 form an opening. At this time, the scraps can fall into the feeding part or collection container of the PVC film calender.

[0051] like Figure 1 As shown, a collecting box 15 is placed on one side of the upper end surface of the base 1, and the opening of the collecting box 15 is aligned with the right end of the material receiving frame 11.

[0052] Specifically, when it is difficult to align the right end of the material receiving frame 11 with the feed port of the PVC film calender, the collecting box 15 can be placed at the lower right side of the material receiving frame 11, and then the scraps fall into the collecting box 15, and then the scraps are poured into the feed port of the PVC film calender by manual transportation.

[0053] like Figure 1 , Figure 2 , Figure 8 As shown, the connection between the two crushing blades 40 and the processing box 34 is fixedly connected to a gear 9 via a rotating shaft, and the two gears 9 are meshed with each other. A motor 6 33 is fixedly connected to one side of the rear end face of the processing box 34, and the output end of the motor 6 33 is fixedly connected to the right crushing blade 40 via a rotating shaft. The front end face of the processing box 34 is fixedly connected to a shell 1 41.

[0054] Specifically, the motor 6 33 is used to drive the crushing blade 40 on the right to rotate, and the crushing blade 40 on the left can be rotated under the cooperation of the two gears 9. The two crushing blades 40 rotate in different directions at the same time, so that the scraps can be cut and crushed.

[0055] like Figure 5 and Figure 6 As shown, a motor 7 35 is fixedly connected to one side of the rear end face of the slider 2 23, the output end of the motor 7 35 passes through the slider 2 23 and the end is fixedly connected to the groove plate 24, a spring damper 25 is fixedly connected to the right end of the inner side of the groove plate 24, the piston end of the spring damper 25 is fixedly connected to the slider 3 27, a motor 26 is fixedly connected to one side of the upper end of the groove plate 24, the output end of the motor 26 is fixedly connected to the eccentric block 32 through a rotating shaft, and the eccentric block 32 is fitted with the slider 3 27.

[0056] Specifically, when the shovel frame 16 moves to above the processing box 34, the motor seven 35 is started, the groove plate 24 can be rotated counterclockwise, the shovel frame 16 can be tilted, and the scraps can begin to fall. At the same time, the motor two 26 can be started to drive the eccentric block 32 to rotate, so that the eccentric block 32 continuously squeezes the slider three 27, and the slider three 27 is reset under the action of the spring damper 25, so that the shovel frame 16 can vibrate. When the shovel frame 16 vibrates, the falling speed of the scraps can be accelerated to avoid the scraps being stuck inside the shovel frame 16.

[0057] like Fig. 9 As shown, the left end of the support column three 39 is fixedly connected to the dust box 6, and an exhaust fan 36 is arranged on one side of the dust box 6. The upper end of the dust box 6 is connected to a hose 7, and one end of the hose 7 is connected to a dust hood 8. One end of the dust hood 8 is slidably connected to the processing box 34. Reciprocating screw rods 38 are rotatably arranged at both ends of the left side of the processing box 34. A motor eight 37 is fixedly connected to the left end of the front side of the processing box 34, and the output end of the motor eight 37 is fixedly connected to the reciprocating screw rod 38.

[0058] Specifically, when the scraps are being crushed, the dust hood 8 is at the front end and will not affect the falling of the scraps. After the scraps are crushed, the exhaust fan 36 and the motor 8 37 can be started. The exhaust fan 36 generates negative pressure, which makes the dust hood 8 generate suction. The residual scraps attached to the surface of the crushing blade 40 will enter the dust box 6 through the hose 7 under the action of the suction force. Moreover, under the action of the continuous rotation of the reciprocating screw 38, the dust hood 8 slides back and forth, so that the adsorption range is expanded, thereby improving the collection effect of the residual scraps on the surface of the crushing blade 40, and avoiding the situation where the scraps are stuck on the surface of the crushing blade 40 and affect the subsequent use.

[0059] like Figure 1 As shown, a box door is provided at the front end of the dust collecting box 6.

[0060] Specifically, when a certain amount of scraps are accumulated inside the dust box 6, the scraps can be taken out by opening the box door, and the taken out scraps can be reused.

[0061] Working principle: add the scraps to be crushed to the top of the processing box 34, use the motor 6 33 to drive the crushing blade 40 on the right to rotate, and the crushing blade 40 on the left can be rotated with the cooperation of the two gears 9. The two crushing blades 40 rotate in different directions at the same time to cut and crush the scraps, and then move the shovel frame 16 with the cooperation of the slider 1 21 and the slider 2 23. The initial position of the slider 1 21 is at the uppermost end of the slide bar 1 20, and the initial position of the slider 2 23 is at the rightmost end of the slide bar 22. Then, first move the slider 1 21 downward on the slide bar 1 20 to move the shovel frame 16 downward until the bottom of the shovel frame 16 is aligned with the bottom of the inner side of the receiving frame 11. The shovel frame 16 is fitted with the side walls of the material receiving frame 11 at the front and rear ends, and the baffle plate 12 is driven to move downward so that the upper end surface of the baffle plate 12 is flush with the bottom of the material receiving frame 11. The baffle plate 12 prevents the scraps from falling into the right end of the material receiving frame 11, causing the bottom of the shovel frame 16 to press the scraps. Then the slider 23 is driven to slide on the slide bar 22, so that the slider 23 moves from right to left, and the scraps are shoveled into the shovel frame 16 by the shovel frame 16 until the left end of the shovel frame 16 is against the left end of the material receiving frame 11. Then the slider 121 and the slider 23 are driven to move, first returning the shovel frame 16 to its initial position, and then moving the shovel frame 16 to the left. The material frame 16 comes to the top of the processing box 34, and then the groove plate 24 is driven to rotate counterclockwise, so that the shoveling frame 16 can be tilted, so that the scraps fall into the processing box 34 again, and are crushed for the second time under the rotation of the crushing blade 40. The scraps that have been crushed for the second time fall into the receiving frame 11 again, and then the above-mentioned shoveling operations are repeated multiple times, so that the scraps can be crushed multiple times, which can greatly reduce the crushing dead angle and achieve better crushing effect; after the crushing work is completed, the receiving frame 11 can be driven to rotate clockwise to tilt the receiving frame 11, so that the scraps slide to the left end of the baffle plate 13 under the action of gravity, and then the baffle plate 13 is driven to rotate counterclockwise to form an opening with the baffle plate 13 and the right end of the receiving frame 11. The crushed scraps can fall into the feed port of the PVC film calender or the collection container. At this point, the scraps are recycled. After the crushing of the scraps is completed, the exhaust fan 36 and the motor 8 37 can be started. The exhaust fan 36 generates negative pressure, which makes the dust hood 8 generate suction. The residual scraps attached to the surface of the crushing blade 40 will enter the dust box 6 through the hose 7 under the action of the suction force. Moreover, under the action of the continuous rotation of the reciprocating screw rod 38, the dust hood 8 slides back and forth, so that the adsorption range is expanded, thereby improving the collection effect of the residual scraps on the surface of the crushing blade 40, and avoiding the situation where the scraps are stuck on the surface of the crushing blade 40 and affect the subsequent use.
