Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment for film blowing machines, and particularly relates to a waste edge recycling device for film blowing of a film blowing machine. Background Technique

[0002] A film blowing machine is a device that heats and melts plastic particles and then blows them into films. After dissolving and mixing plastics (such as polyethylene PE, polypropylene PP, polyvinyl chloride PVC, etc.) at a high temperature (about 150 degrees Celsius) to become a viscous plastic state, it is blown into a film plastic bag. Its structure mainly consists of an extrusion system, a transmission system, a heating and cooling system, and a control system.

It includes a frame body connected with a trimming knife. On the side of the frame body away from the winding roller, a long strip-shaped collecting hopper is fixedly connected through an auxiliary plate. The auxiliary plate is fixedly connected to the frame body, and the end of the collecting hopper is fixedly connected to the auxiliary plate. The length of the collecting hopper is equal to the width of the frame body. A collecting box is communicated below the collecting hopper. The top height of the collecting hopper is flush with the trimming knife. An auxiliary notch is provided on the side of the top of the collecting hopper close to the trimming knife. An auxiliary roller is rotatably connected in the auxiliary notch. A discharging rod is fixedly connected in the inner wall of the collecting hopper. The discharging rod is made of iron.

Detailed implementation manners

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. The described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0020] Please refer to Figures 1-4, the present utility model provides a technical solution: a waste edge recycling device for a blown film machine, including a base 1 placed on a flat ground. A support frame 2 is fixedly installed on the upper surface of the base 1. The support cylinder on the upper part of the support frame 2 supports the plastic film. A trimming knife 201 is fixedly installed on the right side of the support frame 2, and the trimming knife 201 cuts the waste edges on both sides of the plastic film. A first motor 3 is fixedly installed on the upper surface of the base 1. A turntable 301 is fixedly installed on the output shaft of the first motor 3. When the first motor 3 rotates, the turntable 301 can be rotated. A convex block 302 is fixedly connected to the edge of the upper surface of the turntable 301. When the turntable 301 rotates, the convex block 302 rotates accordingly. The movement trajectory of the convex block 302 is a circle. A slide rail 308 is fixedly installed on the upper surface of the base 1. The length of the slide rail 308 is sufficient to prevent the moving plate 303 from falling off. There are two slide rails 308 and they are parallel to each other. The slide rails 308 are located on both sides of the first motor 3. A moving plate 303 is slidably connected between the slide rails 308, and the moving plate 303 can move back and forth. A chute is provided in the middle of the moving plate 303, and the chute cooperates with the convex block 302. When the turntable 301 rotates, the convex block 302 rotates accordingly. The convex block 302 generates movement in the front-back direction and can move in the chute, causing the moving plate 303 to move back and forth. A support seat 304 is fixedly connected to the upper surface of the moving plate 303. The support seat 304 moves back and forth with the moving plate 303. A second motor 305 is fixedly installed on the top of the support seat 304. The second motor 305 moves back and forth with the moving plate 303 and the support seat 304. When the second motor 305 rotates, the waste edges can be collected. Square mounting shafts 306 are fixedly installed on the output shafts on both sides of the second motor 305. A winding cylinder 307 is provided outside the square mounting shafts 306. When the second motor 305 rotates, the square mounting shafts 306 rotate, causing the winding cylinder 307 to rotate and collect the waste edges. At the same time, when the second motor 305 moves back and forth, the square mounting shafts 306 move back and forth, and the winding cylinder 307 moves back and forth, preventing the waste edges from accumulating at a certain place on the winding cylinder 307. And since the waste edges are wound on the surface of the winding cylinder 307, they will gradually accumulate and the winding radius will gradually increase. Therefore, the rotation speed of the second motor 305 will become slower and slower to balance the problem of too fast winding speed caused by the gradually increasing winding radius.

[0021] Among them, a first support 101 is fixedly installed on the left side of the upper surface of the base 1. A first roller 102 is provided on the upper part of the first support 101. When the first roller 102 rotates, the cut plastic film is collected. A second support 103 is fixedly installed on the right side of the upper surface of the base 1. A second roller 104 is provided on the upper part of the second support 103. The unprocessed plastic film is wound outside the second roller 104.

[0022] Among them, a plastic film is provided on the outer sides of the first rotating roller 102 and the second rotating roller 104. The plastic film moves from bottom to top. A support cylinder is provided at the upper part of the support frame 2. The surface of the support cylinder is smooth. The plastic film contacts the support cylinder. The edge cutting knife 201 presses on the support cylinder to cut the plastic film. The waste edges cut off pass above the support cylinder and move downward.

[0023] Among them, a limit frame 4 is fixedly installed on the side surface of the support frame 2, and the limit frame 4 limits the waste edges.

[0024] Among them, a square hole is opened in the middle of the coiling cylinder 307. The square hole is matched with the square mounting shaft 306. The coiling cylinder 307 is of a detachable design. After coiling, it can be removed and a new coiling cylinder 307 can be replaced. The second motor 305 rotates, the square mounting shaft 306 rotates, and the coiling cylinder 307 rotates to collect the waste edges. After installation, the coiling cylinder 307 is firmly connected and will not become loose.

[0025] Among them, a driving motor is fixedly installed on the front side of the first support 101. The driving motor is fixedly connected to the first rotating roller 102. The driving motor rotates the first rotating roller 102 to make the plastic film move.

[0026] Working principle: When in use, the first rotating roller 102 rotates to make the plastic film move. The edge cutting knife 201 cuts the waste edges on both sides of the plastic film. The second motor 305 rotates, the square mounting shaft 306 rotates, and the coiling cylinder 307 rotates to collect the waste edges. At the same time, the first motor 3 rotates, the turntable 301 rotates, and the convex block 302 rotates accordingly. The convex block 302 moves in the front-back direction, making the moving plate 303 move back and forth. The second motor 305 moves back and forth with the moving plate 303 and the support seat 304. The square mounting shaft 306 moves back and forth, and the coiling cylinder 307 moves back and forth to prevent the waste edges from accumulating at a certain place on the coiling cylinder 307.

[0027] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes and modifications can be made to these embodiments without departing from the principle of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
