Description

Technical Field

[0001] This utility model relates to the field of plastic film production technology, specifically to a plastic film slitting and packaging device. Background Technology

[0002] In the field of plastic film production and processing, especially in the production scenarios of small and medium-sized enterprises, the cutting and boxing of plastic film has long relied on traditional manual operation mode. At present, these enterprises usually first use simple cutting equipment to cut rolls of plastic film into single pieces of preset size. Then, workers manually sort and stack the cut plastic films one by one and put them into the corresponding boxes, and finally complete the sealing operation of the boxes.

[0003] However, in this traditional production method, during the manual boxing process, workers' hands come into direct contact with the plastic film. Sweat, grease, dust and other impurities on their hands can easily adhere to the surface of the plastic film, causing secondary pollution. For some plastic film products with high cleanliness requirements, such as food packaging film and medical supply packaging film, this secondary pollution can seriously affect product quality and may even lead to product scrapping, causing economic losses to enterprises.

[0004] Secondly, the speed of manual boxing is limited by the workers' skill level and physical condition, making it difficult to achieve stable and efficient continuous production. Workers need to sort and stack the cut plastic films piece by piece. During this process, improper operation may cause wrinkles and misalignments in the film, further increasing the difficulty of boxing and prolonging the boxing time. With the continuous increase in market demand for plastic film products and the gradual improvement of enterprises' requirements for production efficiency, this manual cutting and boxing method can no longer meet the needs of modern production, which seriously restricts the improvement of enterprise capacity and large-scale development.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-6 The plastic film slitting and boxing device in this embodiment includes a base plate 1, on which a box feeding assembly 5, a transfer assembly 2, a cutting and feeding assembly 4 and a top cover assembly 3 are installed. The components work together to realize the automated process of plastic film slitting, boxing and sealing.

[0026] like Figure 2 The box feeding assembly 5 includes a double-belt conveyor 51 fixed on the base plate 1. The double-belt conveyor 51 is located below the cutting and feeding assembly 4 and is used to convey the stacked boxes. The double-belt conveyor 51 is equipped with multiple sets of limiting parts. The limiting parts include two sets of limiting cylinders 52 fixed inside the double-belt conveyor 51. The piston rod of the limiting cylinder 52 is fixed with a concave limiting plate 53. When the box is conveyed on the double-belt conveyor 51, the limiting cylinder 52 drives the limiting plate 53 to extend. The concave structure fits against the side of the box to limit the box. The first set of limiting plates from right to left is lifted up to play a pre-waiting role. The second set of limiting plates is lifted up to limit the stacked box to a designated position for boxing.

[0027] like Figure 5 The transfer assembly 2 includes a box transfer section fixed to the base plate 1 and located on the side of the double belt conveyor 51, and a transfer frame 21 fixed at the tail end of the double belt conveyor 51. The box transfer section can clamp and lift the uppermost box of the stacked screw to a suitable height for the cutting and conveying assembly 4 to pack the box. After the box is packed, it is transferred to the transfer frame 21 to wait for the next transfer process.

[0028] The box-transfer unit includes a side frame 29 fixed on the base plate 1. The side frame 29 is located between the side of the dual-belt conveyor 51 and the transfer frame 21. A second linear module 210 is installed on the side frame 29. A third linear module 211 is installed on the moving end of the second linear module 210. A U-frame 212 is fixed on the moving end of the third linear module 211. A push cylinder 213 is installed on the protruding end of the U-frame 212. The top ends of the two sets of push cylinders 213 are distributed opposite to each other. The second linear module 210 and the third linear module 210 drive the U-frame 212 to move to the box position. The push cylinders 213 extend and retract to clamp the box, thereby lifting the box from the dual-belt conveyor 51 to the specified height to complete the filling. After filling, the box is transferred to the transfer frame 21.

[0029] In addition, two sets of L-shaped baffles 22 are fixed in the top right slide of the transfer rack 21, and two side plates 23 are fixed on the outward side of the top right slide. Side push cylinders 24 are installed on the side plates 23 and are placed at an angle. The piston rod of the side push cylinder 24 is fixed with a V-shaped side push block 25. After the box is transferred to the transfer rack 21, the side push cylinder 24 drives the side push block 25 to extend. The V-shaped side push block pushes the box to fit against the corresponding baffle 22 to fix and position the box.

[0030] Meanwhile, a transverse movement part is also installed on the transfer frame 21. The transverse movement part includes a first linear module 26 installed inside the transfer frame 21. A push cylinder 27 is installed at the moving end of the first linear module 26. The piston rod of the push cylinder 27 is fixed with a push plate 28. After positioning, the push cylinder 27 drives the push plate 28 to extend out and contact the box, lifting the box above the baffle 22. Then the first linear module 26 drives the push plate 28 to move and push the box to the sealing station.

[0031] like Figure 3-4 The cutting and feeding assembly 4 includes an upper frame 41 fixed on the base plate 1 and a roll frame 410 opposite to the upper frame 41. The roll frame 410 is used to hold rolls of plastic film. A T-shaped shelf 411 is fixed on the inner side of the roll frame 410. The plastic film pulled out from the shelf 411 provides support. A knife groove 412 is provided on the shelf 411. The upper frame 41 is equipped with a film pulling part, a film cutting part and a film feeding part that cooperate with each other, thereby completing the cutting and feeding of the rolls of plastic film.

[0032] The film stretching section includes two sets of oppositely distributed sixth linear modules 44 installed inside the upper frame 41. The moving end of the sixth linear module 44 is fixed with a pair of plates, and each pair of plates is equipped with a clamping cylinder 45. The clamping cylinder 45 is opposite to the roll frame 410 and located on both sides of the partition plate 411. The sixth linear module 44 drives the clamping cylinder 45 to move, and the clamping cylinder 45 clamps the plastic film, thereby stretching the plastic film from the roll frame 410 to the shelf 411. Therefore, the position of the plastic film being stretched is always the same, and consistency can be maintained.

[0033] In addition, the film cutting section includes a fifth linear module 42 installed on the side opposite to the upper frame 41 and the roll frame 410. The moving end of the fifth linear module 42 is equipped with a cutter 43 that is adapted to the cutter groove 412. When the plastic film is stretched to a preset length, the fifth linear module 42 drives the cutter 43 to move laterally and cooperate with the cutter groove 412 to complete the cutting of the plastic film.

[0034] Meanwhile, the film feeding unit includes a seventh linear module 46 installed on the top of the upper frame 41. The moving end of the seventh linear module 46 is fixed with a crossbeam 47 that slides with the upper frame 41. A lowering cylinder 48 is installed at the bottom of the crossbeam 47. A second adsorption device 49 is installed on the piston rod of the lowering cylinder 48. After cutting, the lowering cylinder 48 drives the second adsorption device 49 to move down and adsorb the plastic film. Then, the seventh linear module 46 drives the crossbeam 47 to move and move the plastic film to the top of the box to be packed. The lowering cylinder 48 retracts and puts the plastic film into the box, thereby completing the automatic cutting and boxing of the plastic film.

[0035] like Figure 6 The top cover assembly 3 includes a cover-moving part located at the tail end of the transverse part and a push-pull part mounted on the base plate 1. Through the cooperation of the cover-moving part and the push-pull part, the cover can be moved onto the box to complete the sealing operation.

[0036] The pusher includes a platform 31 fixed on the base plate 1. The platform 31 is provided with four guide rods 32 and a pusher cylinder 33 is installed at the bottom. The piston rod of the pusher cylinder 33 is fixed with a pusher plate 34 fixed to the top of the guide rods 32. When the cover of the stacked screw is placed on the pusher plate, the pusher cylinder 33 drives the pusher plate 34 to move upward step by step, so that the top cover is always in the optimal material picking position. The guide rods 32 ensure that the pusher plate 34 moves smoothly.

[0037] Additionally, the lid-moving part includes a frame 35 fixed on the base plate 1. A fourth linear module 36 is mounted on the frame 35. A push-down cylinder 37 is mounted on the moving end of the fourth linear module 36. A first adsorption device 38, which can be located above the push-top plate 34, is mounted on the piston rod of the push-down cylinder 37. The fourth linear module 36 drives the push-down cylinder 37 and the first adsorption device 38 to move to the lid storage position. The push-down cylinder 37 drives the first adsorption device 38 to move down and adsorb the lid. Then, the fourth linear module 36 moves the lid to the top of the box body. The push-down cylinder 37 drives the first adsorption device 38 to move down and close the lid on the box body, completing the sealing operation.

[0038] The working principle of the above embodiments is as follows:

[0039] The rolled plastic film is installed on the roll rack. The box to be loaded with screw stacks is placed on the dual-belt conveyor. The box cover is placed on the push plate. The dual-belt conveyor starts to transport the box. The limit cylinder drives the limit plate to limit the box, so that the box is in the pre-filling position. The second and third linear modules drive the U-frame to move. The push cylinder clamps the box and lifts it to a suitable height. The clamping cylinder clamps the plastic film. The sixth linear module drives the stretching plastic film to be placed on the shelf. The fifth linear module drives the cutter to move and cooperate with the cutter groove to cut the film. The bottom cylinder drives the second adsorption device to adsorb the cut plastic film. The seventh linear module drives the transfer. The box is placed on top of the box and placed inside. After filling, the second linear module moves the box to the transfer frame. The side push cylinder on the transfer frame drives the side push block to cooperate with the baffle to straighten the box. The top push cylinder drives the top push plate to lift and lift the box. The first linear module then moves the box to the middle of the transfer frame and straightens it again by the side push cylinder. The above operation is repeated to deliver the box to the end of the transfer frame for sealing. The fourth linear module cooperates with the downward push cylinder to move horizontally and downward, thereby driving the first adsorption device to move the box cover to the top of the box and seal it. The top push cylinder drives the top push plate to move upward step by step, so that the cover is always kept in the optimal material picking position.

[0040] The entire workflow is now complete, automating the cutting, boxing, and sealing of the plastic film.
