Technical Field
[0001] This utility model relates to the field of plastic wrap recycling technology, and in particular to a plastic wrap compression and recycling device. Background Technology
[0002] In the warehousing and logistics of cigarettes, in order to prevent the packaging of cigarettes from being damaged due to squeezing and collision, multiple packs of cigarettes need to be sealed and repackaged with plastic film. When the cigarettes are transported to their destination, the plastic film needs to be removed. The plastic film is usually made of polyethylene (PE). After use, it expands in volume and takes up a lot of space when stacked for storage or thrown into the trash can, causing inconvenience to storage and transportation. In addition, the plastic film is flammable and can easily cause safety problems if it is stacked at will. Utility Model Content
[0003] The purpose of this invention is to provide a plastic sealing film compression and recycling device to solve the problems existing in the prior art.
[0004] This utility model is implemented by the following technical solution: a plastic sealing film compression and recycling device, which includes a fixed frame, a compression box, an electric push rod, a sealing base plate, gears, a rack and pinion, and a recycling box; The compression chamber, which has an open top and bottom, is provided inside the fixed frame, and a feed inlet is provided on the front side wall of the compression chamber; The compression chamber contains a horizontally movable extrusion plate, and the extrusion plate slides in contact with the inner wall of the compression chamber on all four sides. The top plate of the fixed frame contains an electric push rod, the base of which is fixed to the top plate, and the telescopic end of which is vertically downward and fixedly connected to the upper surface of the extrusion plate. A sealing base plate that can move back and forth is provided at the bottom of the compression box. The upper surface of the sealing base plate slides in contact with the bottom edge of the compression box. A rack is provided at the bottom of the sealing base plate along the back and forth direction. A support plate is fixed on the support leg of the fixed frame below the sealing base plate. A drive motor is fixed on the support plate. A gear that meshes with the rack is coaxially sleeved on the output shaft of the drive motor. The recycling box is placed on the ground below the compression box.
[0005] Preferably, a crushing box is provided at the feed inlet of the compression box, and two crushing rollers with interlocking crushing teeth are horizontally arranged in the crushing box. Two rotary motors are fixedly installed on one side of the crushing box by a support plate, and the output ends of the two rotary motors rotate through the side wall of the crushing box and are fixedly connected to the crushing rollers.
[0006] Preferably, two symmetrical guide plates are inclined above the two crushing rollers inside the crushing box. The top ends of the two guide plates extend upward to the feed inlet of the crushing box, and the bottom ends of the two guide plates extend downward to the top of the two crushing rollers.
[0007] Preferably, limit strips are fixed on all four side walls inside the compression chamber, and the bottom inclined surface of the limit strips is in close contact with the inclined surface of the extrusion plate.
[0008] Preferably, a first limiting block is fixed on the upper surface of the sealing base plate outside the compression box, and a fixing block is fixed on the fixing frame on the same side as the first limiting block. When the bottom opening of the compression box is completely closed by the sealing base plate, the first limiting block contacts the outer wall of the compression box. When the bottom opening of the compression box is fully open, the first limiting block contacts the fixing block.
[0009] Preferably, a guide rod is movably installed vertically on the top plate on both sides of the electric push rod, and the bottom end of each guide rod passes through the top plate and is fixedly connected to the upper surface of the extrusion plate.
[0010] Advantages of this invention: This invention features two crushing rollers. The two rollers rotate inwards towards each other, winding in the plastic sealant. The crushing teeth of the two rollers interlock, squeezing and shearing to break the sealant. The broken sealant then enters a compression chamber. Additionally, an electric push rod extends, causing the extrusion plate to move downwards, compressing the sealant in the compression chamber and reducing its volume. The heating temperature of the heating wires inside the compression chamber, the extrusion plate, and the sealing base plate is controlled at approximately 200°C, softening the sealant without melting it. Once softened, the sealing base plate is moved away from the compression chamber by a forward-rotating drive motor, discharging the compressed sealant. If the softened sealant adheres to the lower surface of the extrusion plate, the drive motor reverses to retract the sealing base plate. The sharp corner of the sealing base plate moves along the lower surface of the extrusion plate, scraping off the adhered sealant and causing it to fall into a recycling bin. This avoids indiscriminate stacking, reduces the volume of the softened and compressed sealant, minimizes storage space, and facilitates timely transportation. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.
[0018] like Figures 1-5 As shown, a plastic sealing film compression and recycling device includes a fixed frame 1, a compression box 2, a crushing box 3, a crushing roller 4, a guide plate 5, an extrusion plate 7, an electric push rod 6, a sealing base plate 8, a gear 9, a rack 10, and a recycling box 11. Inside the fixed frame 1 is a compression box 2 with open top and bottom. Heating wires are embedded in the four inner walls of the compression box 2. A feed inlet 2.1 is opened on the front side wall of the compression box 2. The plastic seal film enters the compression box 2 through the feed inlet 2.1. A crushing box 3 is provided at the feed inlet 2.1 of the compression box 2. Two crushing rollers 4 with interlocking crushing teeth are arranged horizontally in the crushing box 3. The crushing teeth of the two crushing rollers 4 interlock, crush, and shear to crush the plastic seal film. Two rotary motors 13 are fixedly installed on one side of the crushing box 3 by a support plate 12. The output ends of the two rotary motors 13 rotate through the side wall of the crushing box 3 and are fixedly connected to the corresponding crushing rollers 4 respectively. The rotary motors 13 are controlled to make the two crushing rollers 4 rotate inward relative to each other and roll in the plastic seal film. Two symmetrical guide plates 5 are inclined above the two crushing rollers 4 inside the crushing box 3. Both sides of each guide plate 5 extend to be fixedly connected to the side wall of the crushing box 3. The top of the two guide plates 5 extends upward to the feed inlet of the crushing box 3, and the bottom of the two guide plates 5 extends downward to the top of the two crushing rollers 4. The guide plates 5 play a guiding role, which facilitates the plastic sealing film to enter between the two crushing rollers 4. Limiting strips 14 are fixed on the four side walls inside the compression box 2. The bottom inclined surface of the limiting strip 14 is in close contact with the inclined surface of the extrusion plate 7. The limiting strip 14 is used to restrict the extrusion plate 7 from moving upward. A pressing plate 7 that can move up and down is horizontally arranged inside the compression box 2. An electric heating wire is embedded in the lower surface of the pressing plate 7, and the pressing plate 7 slides in contact with the inner wall of the compression box 2 on all four sides. An electric push rod 6 is provided on the top plate 1.1 of the fixed frame 1. The base of the electric push rod 6 is fixed on the top plate 1.1, and the telescopic end of the electric push rod 6 is vertically downward and fixedly connected to the upper surface of the pressing plate 7. The pressing plate 7 moves up and down by controlling the telescopic extension of the electric push rod 6. When the pressing plate 7 moves downward, it squeezes the plastic sealing film in the compression box 2 and reduces the volume of the plastic sealing film. A guide rod 15 is vertically mounted on the top plate 1.1 on both sides of the electric push rod 6. The bottom end of each guide rod 15 passes through the top plate 1.1 and is fixedly connected to the upper surface of the extrusion plate 7. The guide rod 15 plays a guiding role, which facilitates the stable up and down movement of the extrusion plate 7. A sliding groove 1.2 with opposite positions is provided on the inner side of each support leg at the bottom of the compression chamber 2. A sealing base plate 8 that can move back and forth is installed in the sliding groove 1.2. An electric heating wire is embedded in the upper surface of the sealing base plate 8. The sealing base plate 8 is used to seal the bottom opening of the compression chamber 2. A rack 10 is provided at the bottom of the sealing base plate 8 along the back and forth direction. A support plate 16 is fixed on the support leg of the fixing frame 1 below the sealing base plate 8. A drive motor 17 is fixed on the support plate 16. A gear 9 that meshes with the rack 10 is coaxially sleeved on the output shaft of the drive motor 17. The upper surface of the sealing base plate 8 slides in contact with the bottom edge of the compression chamber 2. Controlling the output shaft of the drive motor 17 to rotate drives the gear 9 to rotate, causing the rack 10 to move back and forth, thereby moving the sealing base plate 8 relative to the compression chamber 2 to facilitate the discharge of compressed waste. The compression box 2 has a plastic sealant film. A first limiting block 18 is fixed on the upper surface of the sealing base plate 8 outside the compression box 2. A fixing block 18 is fixed on the fixing frame 1 on the same side as the first limiting block 18. When the bottom opening of the compression box 2 is completely closed by the sealing base plate 8, the first limiting block 18 contacts the outer wall of the compression box 2. When the bottom opening of the compression box 2 is completely open, the first limiting block 18 contacts the fixing block 19. The fixing block 19 can limit the movement space of the first limiting block 18. The sealing base plate 8 drives the first limiting block 18 to move back and forth between the outer wall of the compression box 2 and the fixing block 19 through the cooperation of gear 9 and rack 10, thereby limiting the movement range of the sealing base plate 8. A recycling box 11 is placed on the ground below the compression box 2. The recycling box 11 is used to collect the plastic sealant film discharged from the compression box 2.
[0019] Operating principle: First, the removed plastic wrap is put into the feed inlet of the crushing box 3. The rotary motor 13 is controlled to make the two crushing rollers 4 rotate inward relative to each other and roll in the plastic wrap. The crushing teeth of the two crushing rollers 4 bite, squeeze and shear each other to crush the plastic wrap. The crushed plastic wrap enters the compression box 2. Secondly, the electric push rod 6 is extended to move the extrusion plate 7 downward, extruding the plastic sealant film inside the compression box 2 and reducing its volume. The heating wires inside the inner wall of the compression box 2, the extrusion plate 7, and the sealing base plate 8 are heated to soften the plastic sealant film. To prevent the plastic sealant film from melting, the heating temperature is controlled at around 200°C. After the plastic sealant film softens, the drive motor 17 is rotated in the forward direction, driving the gear 9 to rotate and causing the rack 10 to move backward, thereby moving the sealing base plate 8 away from the compression box 2 until the first limit block 18 contacts the fixing block 19. Then, control the electric push rod 6 to continue extending, causing the extrusion plate 7 to move downwards, as... Figure 5 As shown, the compression plate 7 continues until its lower surface contacts the edge of the upper surface of the sealing base plate 8, facilitating the discharge of the compressed and softened plastic sealant. When the softened plastic sealant adheres to the lower surface of the compression plate 7, the drive motor 17 is controlled to rotate in the opposite direction, driving the gear 9 to rotate, causing the rack 10 to move forward, and driving the sealing base plate 8 to move along the lower surface of the compression plate 7. This allows the sharp corner of the sealing base plate 8 to scrape off the plastic sealant adhering to the lower surface of the compression plate 7, causing the plastic sealant to fall into the recycling bin 11.
