Description

Technical Field

[0001] The utility model relates to the technical field of packaging film recovery equipment, in particular to a waste packaging film collection device with a compression mechanism. Background Art

[0002] Packaging film mainly refers to the film used for packaging articles, usually including polyethylene film, biaxially oriented polyester, BOPP film and CPP film, etc., which are mainly used for the packaging of food, medicine and textiles. Because the packaging film can ensure the hygiene and safety of the goods, and has the functions of transparency, sealing, fixity (small parts will not fall over during transportation), dust and moisture resistance, etc., the packaging film will be recycled after use, and optimization of recycling is necessary.

[0003] For example, a Chinese utility model patent with announcement number CN211137388U discloses a packaging bubble film cutting device that is easy to collect. Although the above-mentioned prior art can cut the bubble film in width and length, and can sort and collect according to different cutting sizes, saving manpower and material resources, the packaging film wrapped on the article usually has multiple layers, and a heated cutting knife is usually used to cut the packaging film. When the packaging film is cut and collected by the heated cutting knife, the cuts will stick together due to the temperature, resulting in a lot of air inside the collected packaging film. Although it will not increase the weight of the packaging film, the presence of air will prop up the packaging film, resulting in the collected packaging film taking up a lot of collection space. The staff needs to manually release the air and sort and collect it again, which will reduce the collection efficiency of the packaging film. Therefore, it is necessary to design a waste packaging film collection device with a compression mechanism. Utility Model Content

Both ends of the two support rods penetrate through the collecting box and extend to the outside thereof. Limiting plates fixedly installed with the two ends of the adjacent support rods are provided on both sides outside the collecting box, and a retraction spring with one end fixedly installed with the adjacent limiting plate and the other end fixedly installed with the collecting box is sleeved on both ends of the two support rods.

[0014] Through the above technical solution, the retraction spring will pull the two limiting plates to make the two extrusion columns as close as possible to extrude the collected packaging film.

[0015] As a further improvement of the above solution, a partition is fixedly installed inside the collecting box, a plurality of ventilation holes are opened on one side of the partition, a material taking port is opened on one side of the collecting box, and a baffle is rotatably installed on one side of the material taking port.

[0016] Through the above technical solution, the squeezed packaging film will be blocked by the partition and will fall to the material taking port when the exhaust fan stops.

It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0030] Please combine Figure 1-Figure 4 A waste packaging film collection device with a compression mechanism in this embodiment includes a base 1, a collecting platform 2 is provided on one side of the base 1, a material 3 wrapped with a packaging film is provided on one side of the collecting platform 2, a cutting component for cutting the packaging film is provided on one side of the collecting platform 2, a collecting component for collecting the cut packaging film is provided on the other side of the collecting platform 2, a compression component for compressing the collected packaging film is provided on one side of the collecting component, and a driving component for driving the cutting component and the collecting component to move is provided on the collecting platform 2.

[0031] Combination Figure 1 and Figure 2 The cutting assembly includes a mounting plate 401 slidably arranged on one side of the collecting platform 2, a heating base 402 fixedly installed on one side of the mounting plate 401, and a hot cutting knife 403 fixedly installed on one side of the heating base 402. A fixing block 8 is fixedly installed on one side of the mounting plate 401, and a mounting hole is opened on one side of the fixing block 8. A pushing rod 9 is installed inside the mounting hole, and a sensor 10 is fixedly installed on one end of the pushing rod 9. The hot cutting knife 403 only needs to contact the packaging film, and the packaging film will be cut by the heat. The sensor 10 will first contact the material 3 to accurately determine the contact range between the hot cutting knife 403 and the packaging film to avoid damage to the material 3.

[0032] Combination Figure 1, the collection component includes a collection plate 501 that is slidably arranged on one side of the collection platform 2 and is provided with a collection port, a collection cylinder 502 that is fixedly installed on the collection plate 501 through the collection port and is arranged in a conical shape, a collection box 503 that is fixedly connected to one end of the collection cylinder 502, an air extraction pipe 504 that is fixedly connected to one side of the collection box 503, and an air extraction fan 505 that is fixedly connected to one end of the air extraction pipe 504. When the air extraction fan 505 extracts air, the cut packaging film will be sucked into the collection cylinder 502 and thus be squeezed and collected.

[0033] Combined Figure 3 , the compression component includes two support rods 601 that are arranged inside the collection box 503 and are arranged in a "C" shape, and extrusion columns 602 that are rotatably sleeved on each support rod 601. Both ends of the two support rods 601 penetrate through the collection box 503 and extend to the outside thereof. Limiting plates 11 fixedly installed with the two ends of the adjacent support rods 601 are arranged on both sides of the outside of the collection box 503. Retraction springs 12 with one end fixedly installed with the adjacent limiting plate 11 and the other end fixedly installed with the collection box 503 are sleeved on both ends of the two support rods 601. A partition plate 13 is fixedly installed inside the collection box 503. A plurality of ventilation holes are opened on one side of the partition plate 13. A material taking port is opened on one side of the collection box 503. A baffle 14 is rotatably installed on one side of the material taking port. The retraction spring 12 will pull the two limiting plates 11 to make the two extrusion columns 602 as close as possible to squeeze the collected packaging film. The squeezed packaging film will be blocked by the partition plate 13 and will fall at the material taking port when the air extraction fan 505 stops.

[0034] Combined Figure 1 , Figure 2 and Figure 4 , a sliding groove is opened on one side of the collection platform 2. The driving component includes a bidirectional threaded rod 701 arranged inside the sliding groove and a servo motor 702 arranged at one end of the bidirectional threaded rod 701. One end of the bidirectional threaded rod 701 is fixedly installed with the output end of the servo motor 702. Sliding blocks are threadedly sleeved on both ends of the bidirectional threaded rod 701. One side of the mounting plate 401 and one side of the collection plate 501 are fixedly installed with the adjacent sliding blocks. A moving plate 15 is fixedly installed on one side of the collection box 503. A moving groove is opened on one side of the base 1. A moving block fixedly installed with one side of the moving plate 15 is slidably arranged inside the moving groove. A connecting plate 16 fixedly installed with one side of the collection plate 501 is fixedly installed on one side of the moving plate 15. When the servo motor 702 is started, the cutting component and the collection component will move closer to the material 3, which is convenient for cutting and collecting the packaging film. When the collection plate 501 moves, the collection box 503 and the air extraction fan 505 will also move together on the moving plate 15.

[0035] The implementation principle of a waste packaging film collection device with a compression mechanism in the embodiment of the present application is as follows: the material 3 wrapped with the packaging film is placed on the collection platform 2, and the servo motor 702 is started, and the bidirectional threaded rod 701 will rotate, thereby driving the two sliding blocks to move toward a close position together, so that the mounting plate 401 and the collection plate 501 will also move toward the material 3. When the mounting plate 401 moves, the sensor 10 will contact the material 3 before the thermal cutting knife 403. When the sensor 10 contacts the material 3, it will send a command to the servo motor 702, so that the servo The motor 702 stops, so that the hot cutting knife 403 can heat-cut the packaging film. Because the packaging film is relatively soft and the material 3 is relatively hard, the sensor 10 sets the sensing pressure. When it contacts the material 3, the servo motor 702 stops, and the hot cutting knife 403, which lags behind the sensor 10, cuts the packaging film. The position of the push rod 9 can also be adjusted according to the thickness of the packaging film. After the position of the push rod 9 is adjusted, the position of the sensor 10 will be changed, so as to ensure that the hot cutting knife 403 will not damage the material 3. In addition, the material 3 is mostly solid, which will The packaging film is more resistant to high temperatures than the packaging film and is not easily damaged by the hot cutting knife 403. When the packaging film is cut, it will be collected by the collecting tube 502. Because the exhaust fan 505 is constantly exhausting air, suction is generated inside the collecting tube 502 to suck the packaging film into the collecting box 503. When the packaging film enters the collecting box 503, it will be squeezed by the two squeezing columns 602 to discharge the air inside the packaging film. The limiting plate 11 cooperates with the retraction spring 12 to keep the two squeezing columns 602 close to each other. After being squeezed, the packaging film will be sucked onto the partition 13 due to suction. After the packaging film 3 is collected, the machine will be turned off. When the machine is turned off, the suction will disappear, so that the packaging film will fall into the bottom of the collection box 503, and the baffle 14 can be opened to take it out from the material taking port. The baffle 14 can only be opened outward but not inward, so even if the packaging film is not taken out and the machine is turned on again to collect, the packaging film will not move. More packaging films can be accumulated and taken away at one time. This setting can discharge the air inside the packaging film when it is collected, so as to avoid the packaging film occupying the collection space due to more internal air, which causes the staff to manually discharge the air and affects the collection efficiency.

[0036] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
