Description

Technical Field

[0001] The invention relates to the technical field of automatic crushing and recycling of packaging film scraps, and in particular to an automatic crushing and recycling device for packaging film scraps. Background Art

[0002] PE food packaging film is a plastic film widely used in the field of food packaging. The rolled scraps cut off during the processing of the packaging film are usually crushed together to facilitate the centralized recycling and reuse of the packaging film scraps. In the existing technology, the packaging film scraps crushed by the crushing equipment are generally transported to woven bags by pneumatic conveying equipment for recycling.

[0003] However, the traditional method of recycling the crushed packaging film scraps by woven bags has the following problems: 1. In the existing technology, it is generally necessary to manually put the woven bags for recycling on the output pipe of the pneumatic conveying equipment and temporarily fix the woven bags by tightening the ropes. The above-mentioned bagging method is not only cumbersome and inefficient, but also has poor stability in the temporary fixation of the woven bags. It is easy for the woven bags to break away from the output pipe under the influence of the positive pressure output by the pneumatic conveying equipment, thereby causing the leakage of the crushed packaging film scraps, which in turn affects the overall production environment and the normal operation of the operators; 2. During the operation, when the woven bag is filled with the crushed packaging film scraps, it is necessary to stop the crushing equipment and the pneumatic conveying equipment first, and then replace the filled woven bag. At the same time, the replaced filled woven bag needs to be manually tightened and tied with a plastic tie to prevent the debris from leaking. The above operation method is not only inefficient, time-consuming and labor-intensive, but also will lead to more shutdowns of the crushing and recycling equipment and lower overall equipment efficiency when crushing more packaging film scraps. The processing progress of the crushing and recycling of packaging film scraps is slow and the processing efficiency is low.

A motor 1 215 with a driving end fixedly connected to the left end of the rear crushing roller 212 is fixedly provided on the left side of the crushing bucket 211.

[0032] See also Figure 2 and Figure 5 The scrap material supporting portion 22 includes a supporting platform 221 fixedly arranged on the rear side of the crushing bucket 211, and a supporting roller 222 is rotatably provided on the upper side of the supporting platform 221 through a support 1. A supporting rod 223 for supporting the scrap materials of the rolled packaging film is fixedly provided on the upper side of the supporting platform 221 and behind the supporting roller 222 through a support 2. Insertion rods 224 are fixedly provided at the four corners of the upper side of the crushing bucket 211, and a protective plate 225 is slidably docked on all the insertion rods 224, and a feeding trough 226 is provided on the protective plate 225 which passes through the upper and lower parts.

[0033] When the rolled packaging film scraps need to be crushed, the rolled packaging film scraps are first inserted into the supporting rod 223, and the movable end of the rolled packaging film scraps is guided into the feed chute 226 by the upper side of the supporting roller 222, and then the rear crushing roller 212 is driven to rotate by the motor 1 215, and the rear crushing roller 212 then drives the front crushing roller 212 to rotate synchronously relative to each other through the meshing transmission of gear 1 213 and gear 2 214, and the crushing rollers 212 on both sides cooperate to continuously pull and crush the introduced packaging film scraps, wherein the supporting roller 222 can support and guide the lead-out end of the packaging film scraps, and the protective plate 225 can prevent the crushing roller 212 from posing a threat to the safe operation of the operator.

[0036] When the packaging film scraps are crushed in the crushing bucket 211, the packaging film scraps fall downward from the discharge pipe 231 into the delivery pipe 232, and the forward positive pressure is input into the delivery pipe 232 by the blower 233. The scraps then pass through the delivery pipe 232 and are transported forward into the recovery mechanism 3 and the bagging mechanism 4 via the pressure relief ring 234; when the front side of the pressure relief ring 234 is temporarily blocked, the pressure relief hole on the pressure relief ring 234 can release the positive pressure input by the blower 233 in the delivery pipe 232 to avoid damage to the delivery pipe 232 due to excessive pressure.

[0037] See also Figure 1 and Figure 2 The recycling mechanism 3 includes a base 31 arranged in front of the support frame 1, and a conversion component 32 for converting the output port of the crushed scraps of the packaging film is provided on the upper side of the base 31. The conversion component 32 is provided with a driving component 33 for driving the conversion component 32 and a positioning component 34 for docking and positioning the conversion component 32.

[0038] See also Figure 2 、 Figure 3 and Figure 6 The conversion assembly 32 includes a conversion table 321 fixedly arranged on the upper side of the base 31, a rotating table 322 is rotatably arranged inside the conversion table 321, and a plurality of rotating sleeves 323 connected front to back are uniformly rotated circumferentially on the rotating table 322. A square through groove running through the upper and lower sides is provided on the upper side of the conversion table 321, and a feed port connected front to back with the pressure relief ring 234 and the corresponding rotating sleeve 323 is provided on the lower side of the rear surface of the conversion table 321.

[0039] See also Figure 2 and Figure 6 The driving component 1 33 includes a gear ring 1 331 fixedly set on the side surface of the conversion platform 321, the upper side of the gear ring 1 331 is located above the square through groove, and the upper side of the conversion platform 321 is fixedly provided with a motor 2 332 through a support 3, and the driving end of the motor 2 332 is fixedly provided with a gear 333 meshing with the gear ring 1 331.

[0040] See also Figure 2 、 Figure 3 and Figure 6 The positioning assembly 34 includes a positioning ring 341 fixedly arranged on the front side of the corresponding rotating sleeve 323 and connected front and back. A card slot 342 is opened on the side of the positioning ring 341 close to the axis of the rotating table 322. A spring rod is elastically slidably provided on the rotating table 322 and located on the side of the corresponding positioning ring 341 close to the axis of the rotating table 322 through a fourth support. An elastic card block 343 is fixedly provided on one end of the spring rod close to the corresponding positioning ring 341 to engage with the corresponding card slot 342 for positioning.

[0041] The motor 2 332 drives the gear 3 333 to rotate, so that the gear 3 333 drives the rotating platform 322 to rotate in a directional manner by meshing with the gear ring 1 331 (such as Figure 6 As shown by the arrow, the rotating sleeve 323 drives each rotating sleeve 323 to rotate to the bottom side in sequence and stably connect with the feed port and the pressure relief ring 234. In the process of the rotating table 322 driving the rotating sleeve 323 to rotate in a directional manner, the rear side of the rotating table 322 temporarily blocks the pressure relief ring 234 and the front side of the feed port until the next rotating sleeve 323 is connected with the pressure relief ring 234 and the feed port.

[0042] When the rotating sleeve 323 rotates synchronously with the rotating platform 322, the elastic block 343 is stably engaged in the corresponding slot 342 through the spring rod, so that the corresponding positioning ring 341 and its corresponding rotating sleeve 323 cannot rotate along their own rotation axis when no external force is applied.

[0043] See also Figure 1 The bagging mechanism 4 includes a drawstring assembly 41 arranged on the recovery mechanism 3, and the drawstring assembly 41 is provided with a second driving assembly 42 and a clamping assembly 43 that cooperates with the second driving assembly 42 in transmission.

[0044] See also Figure 1 and Figure 3 The beam mouth assembly 41 includes a fixed circular plate 411 fixedly arranged on the front side of the corresponding positioning ring 341, and an output pipe 412 connected to the front and rear of the corresponding positioning ring 341 is fixedly arranged on the front side of the fixed circular plate 411. A gear ring 2 413 is fixedly arranged on the side surface of the fixed circular plate 411, and an arc-shaped connecting plate 414 is fixedly arranged on the front side of the conversion table 321 and at the lower left side of the rotating table 322. An arc-shaped rack 415 engaged with the gear ring 2 413 for transmission is fixedly arranged on the front side of the arc-shaped connecting plate 414.

[0045] In the process of the rotating table 322 driving the rotating sleeve 323 to rotate synchronously in a directional manner, the rotating sleeve 323 on the lower side drives the corresponding positioning ring 341 and the fixed circular plate 411 to rotate synchronously, and the fixed circular plate 411 on the lower side drives the corresponding gear ring 2 413 to rotate synchronously. The gear ring 2 413 on the lower side drives the output tube 412, the driving component 2 42 and the clamping component 43 on the corresponding fixed circular plate 411 to rotate synchronously for a specific number of circles around the rotation axis of the corresponding rotating sleeve 323 through meshing with the arc-shaped rack 415. The card slot 342 on it is then synchronously misaligned with the corresponding elastic card block 343 until the gear ring 2 413 is completely disengaged from the upper end of the arc-shaped rack 415. At this time, the card slot 342 on the positioning ring 341 is also just engaged with the corresponding elastic card block 343 again, and the front side of the feed port and the pressure relief ring 234 is also connected to the rotating sleeve 323 again, wherein the corresponding positioning ring 341 and the gear ring 2 413 are engaged and positioned by the elastic card block 343, so that the corresponding gear ring 2 413 can stably engage with the arc-shaped rack 415 for transmission.

[0046] See also Figure 1 and Figure 7 The driving component 2 42 includes a guide rail 421 symmetrically fixed on the front side of the fixed circular plate 411 and located on the outside of the output tube 412. An electric slider 422 that moves back and forth is slidably provided on the guide rail 421. A spring clip 423 is fixed on the front side of the electric slider 422 through a connecting rod. A support six is ​​symmetrically fixed on the side of the electric slider 422 away from the corresponding guide rail 421.

[0047] See also Figure 1 and Figure 7 The clamping assembly 43 includes a support five symmetrically fixed on the front side of the fixed circular plate 411 and located on the outside of the output tube 412. The paired supports five are vertically distributed with the corresponding paired guide rails 421. Guide rods 431 are symmetrically slidably arranged on the supports five. A sliding plate 432 is fixedly arranged on the end of the symmetrical guide rods 431 close to the corresponding output tube 412. An arc-shaped clamping plate 433 is fixedly arranged at the front end of the sliding plate 432. Supports seven are symmetrically fixed on the sliding plate 432. An elastic pull rod 434 is installed between the support seven and the corresponding support six.

[0048] When the bag is to be sleeved and fixed on the front end of the output tube 412, the bag mouth of the woven bag is first opened and the edges of the opened bag mouth are symmetrically clamped by the symmetrical spring clips 423 respectively. Then, the corresponding electric slider 422 drives the symmetrical spring clips 423 to move backward along the guide rail 421, and the opened bag mouth of the woven bag is synchronously sleeved on the front end of the output tube 412. In the process of moving backward, the electric slider 422 can synchronously pull the sliding plates 432 symmetrical on both sides through the corresponding elastic pull rods 434, and the symmetrical sliding plates 432 drive the corresponding arc clamping plates 433 to move synchronously relative to each other until the electric slider 422 moves to the rear end of the corresponding guide rail 421. At this time, the symmetrical arc clamping plates 433 have also stably clamped and fixed the bag mouth of the woven bag sleeved on the front end of the output tube 412. The above operation method can realize the rapid and stable sleeve fixing of the woven bag on the scrap material output tube 412, thereby preventing the woven bag from detaching from the output tube 412 under the influence of the positive pressure output by the blower 233.

[0049] Before the woven bag fixed on the lowermost output tube 412 is filled with the packaging film scraps input by the feed pipe 232, the corresponding electric slider 422 drives the arc-shaped clamping plate 433 to fix a new woven bag on the upper right output tube 412. When the woven bag on the lowermost side is filled, the motor 2 332 drives the rotating table 322 and each rotating sleeve 323 to rotate in a specific angle through the gear 3 333. The lowermost rotating sleeve 323 then drives the corresponding gear ring 2 413 to engage with the arc-shaped rack 415 for transmission. The corresponding woven bag opening is synchronously rotated around the corresponding woven bag under the drive of the corresponding arc-shaped clamping plate 433 and the output tube 412. The rotating axis of the rotating sleeve 323 rotates a specific number of circles, and the woven bag itself rotates out of position with the corresponding bag opening under the action of its own weight and the gravity of the internal scraps, so that the bag opening of the woven bag is automatically and quickly rotated and tightened. At this time, the tightened bag opening of the woven bag can be directly tied and sealed with a plastic tie, and then the corresponding paired electric sliders 422 are moved forward to release the clamping fixation of the arc-shaped clamping plate 433. Finally, the woven bag can be directly removed from the corresponding spring clip 423 for unloading. At the same time, the new woven bag originally sleeved and fixed on the upper right side output pipe 412 can now be connected to the feed pipe 232 and continue to recycle the packaging film scraps.

[0050] The above-mentioned operation method can realize the rapid conversion of the output tube 412 for outputting packaging film scraps without stopping the machine, so that the woven bags that are pre-attached and fixed can be quickly connected with the filled woven bags, thereby avoiding the pulverizing mechanism 2 from stopping multiple times when crushing a large amount of packaging film scraps, greatly improving the overall crushing and recycling processing efficiency of the packaging film scraps, and by stably and automatically tightening the bag mouth of the woven bag filled with scraps quickly, the overall operating burden of the operator can be reduced, the labor cost can be reduced, and the overall bagging and unloading efficiency can be accelerated.
