Description

Technical Field

[0001] This utility model relates to the field of edge recycling technology for stretch film, specifically an edge recycling machine for stretch film processing. Background Technology

[0002] Stretch film, also known as stretch film, heat shrink film, or elastic film, is a transparent and flexible plastic film with excellent elasticity and strength. Stretch film is usually made of PVC, PE, or LLDPE as the main materials, with corresponding auxiliary materials added. It has advantages such as high toughness, high elasticity, cold resistance, heat resistance, pressure resistance, and water resistance. During processing, the edges of the stretch film are trimmed by a cutting machine.

[0003] In the production line of stretch film, after the raw material is melted, extruded, and calendered, the extruded stretch film needs to be cut into regular shapes. The remaining edge waste from the cutting process generally needs to be recycled. Conventionally, it is collected directly and then recycled in bulk after a certain amount is accumulated. Therefore, special waste recycling bins are needed to allow the remaining waste to fall directly into the nearby bins by gravity. Then, it is manually transported and crushed by a crushing device before being put back into the furnace. This method requires regular waste edge processing, which is time-consuming, labor-intensive, and involves many operations. If the edge waste is not processed in a timely manner, it will accumulate. Therefore, those skilled in the art have provided an edge waste recycling machine for stretch film processing to solve the problems mentioned in the background art. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an edge material recycling machine for stretch film processing. This solves the problem that after the edge material falls into the recycling bin, it needs to be transferred and put back into the furnace for reuse. This method requires regular processing of waste edge material, which is time-consuming, labor-intensive, and involves many operations. If the edge material is not processed in time, it will cause the accumulation of waste edge material.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: an edge material recycling machine for wrapping film processing, comprising a feeding hopper, a crushing roller assembly inside the feeding hopper, a first motor mounted on the rear side of the feeding hopper, a feeding pipe below the feeding hopper, a transfer pipe below the feeding pipe, a fan mounted on one end of the transfer pipe, a conveying hose connected to the end of the transfer pipe away from the fan, a second motor mounted on the bottom side of the transfer pipe, a rotating shaft driven by the output end of the second motor, and helical blades mounted on the rotating shaft.

[0008] Preferably, the first motor is connected to the crushing roller assembly for driving. When scrap material falls into the hopper, the crushing roller assembly crushes the scrap material.

[0009] Preferably, the bottom end of the hopper is connected to the top end of the discharge pipe, and the bottom end of the discharge pipe is connected to the upper side wall of the transfer pipe, thereby forming a complete discharge channel.

[0010] Preferably, the rotating shaft passes through the transfer tube, and the outer side of the spiral blade is in close contact with the inner wall of the feeding tube. When the spiral blade driven by the motor-driven rotating shaft is conveyed downward, the problem of blockage of scrap materials in the feeding hopper and feeding tube can be effectively avoided.

[0011] Preferably, the spiral blades are narrow-pitch spiral blades, which can effectively avoid the problem of scrap material flowing back when the fan starts.

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, this utility model provides an edge material recycling machine for stretch film processing, which has the following beneficial effects:

[0014] Through design, the stretch film edge recycling machine in this utility model consists of a hopper, a feeding pipe, and a transfer pipe. When the edge scrap falls into the hopper, it is crushed by the crushing roller group. The crushed edge scrap is then conveyed to the transfer pipe through the feeding pipe. As the edge scrap passes through the feeding pipe, the spiral blades driven by the motor-driven shaft are conveyed downwards, which can effectively avoid the problem of edge scrap clogging in the hopper and feeding pipe. After the edge scrap is conveyed to the transfer pipe, the fan supplies air into the transfer pipe. Under the blowing of the air, the crushed edge scrap can be conveyed to the designated edge scrap collection point through the conveying hose, thus eliminating the need for repeated transfer of edge scrap and preventing the accumulation problem caused by untimely edge scrap processing.

[0021] Please see Figure 2 , Figure 3 The first motor 3 is connected to the crushing roller group 2 for driving. When scrap material falls into the feeding hopper 1, the crushing roller group 2 crushes the scrap material. The bottom end of the feeding hopper 1 is connected to the top end of the feeding pipe 4, and the bottom end of the feeding pipe 4 is connected to the upper side wall of the transfer pipe 5, thus forming a complete feeding channel. The rotating shaft 9 passes through the transfer pipe 5, and the outer side of the spiral blade 10 is in contact with the inner wall of the feeding pipe 4. When the rotating shaft 9 driven by the motor drives the spiral blade 10 to convey downward, it can effectively avoid the problem of scrap material clogging in the feeding hopper 1 and the feeding pipe 4. The spiral blade 10 adopts a narrow pitch spiral blade, which can effectively avoid the problem of scrap material backflow when the fan starts.

[0022] The stretch film edge recycling machine in this utility model consists of a feeding hopper 1, a feeding pipe 4, and a transfer pipe 5. The feeding hopper 1 is equipped with a crushing roller group 2. A first motor 3 is fixedly installed on the outer wall of the feeding hopper 1 and is connected to the crushing roller group 2 for driving.

The outer wall of the spiral blade 10 is in contact with the inner wall of the feed tube 4.

[0024] When scrap materials fall into the hopper 1, they are crushed by the crushing roller group 2. The crushed scrap materials are then conveyed to the transfer pipe 5 through the discharge pipe 4. As the scrap materials pass through the discharge pipe 4, the spiral blades 10 driven by the motor-driven rotating shaft 9 convey them downwards, effectively preventing the scrap materials from clogging in the hopper 1 and the discharge pipe 4. After the scrap materials are conveyed to the transfer pipe 5, the blower 6 supplies air into the transfer pipe 5. Under the blowing of the air, the crushed scrap materials are conveyed to the designated scrap material collection point through the conveying hose 7. It is worth mentioning that the spiral conveying pipe uses narrow-pitch spiral blades, which can effectively prevent the scrap materials from flowing back. In this application, there is no need to transfer the scrap materials back and forth, and there is no problem of accumulation caused by untimely processing of scrap materials.
