Description

Technical Field

[0001] This utility model relates to the field of shopping bag production technology, and in particular to a cutting device for shopping bag production. Background Technology

[0002] Shopping bags are bags used for shopping. The main types of shopping bags available on the market include: plastic shopping bags, non-woven shopping bags, paper shopping bags, and cotton / linen shopping bags. In today's society, the pursuit of a low-carbon and low-pollution lifestyle has led to a growing demand for shopping bags due to population growth. Given the significant pollution they cause, environmentally friendly shopping bags are now in use. The manufacturing process of plastic shopping bags involves rolling two single-layer films together to form a double-layer film. Then, a cutting device is used to cut the double-layer film into small plastic pieces, which are subsequently heat-pressed to become the plastic bags we use daily.

[0003] Traditional slitting devices used in shopping bag production have some drawbacks. Shopping bags require the film to be slitted during production, but existing slitting machines are prone to film skewing due to external factors. Since the cutting position of the slitting blade is relatively fixed, it is difficult to adapt to the film's tilt and slitting accordingly, thus reducing slitting efficiency. Utility Model Content

[0004] The main objective of this invention is to provide a cutting device for the production of shopping bags, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A slitting device for shopping bag production includes a slitting machine and a mover. A slitting auxiliary mechanism is provided at the upper end of the mover. The slitting auxiliary mechanism includes a fixed chamber fixedly connected to the upper end of the mover. A guide groove is provided at the front end of the fixed chamber. A limiting frame is fixedly connected to the inner wall of the fixed chamber. A sliding block is slidably connected to the inner side of the limiting frame. A moving plate is slidably connected to the inner side of the guide groove. A scale strip is embedded inside the moving plate. A tool holder is fixedly connected to the front end of the moving plate. A slitting blade is movably connected to the inner side of the tool holder via a rotating shaft with damping. An adjusting block is fixedly connected inside the sliding block.

Detailed Implementation

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figure 1-4 As shown, a slitting device for shopping bag production includes a slitting machine 1 and a mover 3. A slitting auxiliary mechanism 6 is provided at the upper end of the mover 3. The slitting auxiliary mechanism 6 includes a fixed chamber 61 fixedly connected to the upper end of the mover 3. A guide groove 62 is provided at the front end of the fixed chamber 61. A limiting frame 63 is fixedly connected to the inner wall of the fixed chamber 61. A sliding block 64 is slidably connected to the inner side of the limiting frame 63. A moving plate 65 is slidably connected to the inner side of the guide groove 62. A scale strip 66 is embedded inside the moving plate 65. A tool holder 67 is fixedly connected to the front end of the moving plate 65. A slitting blade 68 is movably connected to the inner side of the tool holder 67 through a rotating shaft damping. An adjusting block 69 is fixedly connected inside the sliding block 64. A rotating ring 610 is movably connected inside the adjusting block 69. A control ring 611 is fixedly connected inside the fixed chamber 61. A connecting rod 612 is threadedly connected to the inner side of the control ring 611.

[0021] In this embodiment, a knob 613 is fixedly connected to the rear end of the linkage 612, the front end of the sliding block 64 is fixedly connected to the rear end of the moving plate 65, the linkage 612 passes through the interior of the adjusting block 69, the linkage 612 and the adjusting block 69 are movably connected, the rear end of the rotating ring 610 is fixedly connected to the front end of the linkage 612, and the diameter of the rotating ring 610 is larger than the diameter of the linkage 612.

[0022] Specifically, rotating knob 613 causes connecting rod 612 to rotate within control ring 611, and moving connecting rod 612 within control ring 611. This causes connecting rod 612 to push adjusting block 69 via rotating ring 610, which in turn causes adjusting block 69 to slide sliding block 64 within limiting frame 63. Limiting frame 63 then causes moving plate 65 to slide within guide groove 62, which in turn causes moving plate 65 to move sliding blade 68. By observing the distance the scale bar 66 extends from moving plate 65 through guide groove 62, the movement distance of sliding blade 68 can be determined, allowing for accurate assessment of the sliding blade 68's movement. The slitting blade 68 is moved by adjusting the distance, and then pulled to rotate within the blade holder 67, thereby adjusting its angle to adapt to the tilt angle of the film. By rotating the connecting rod 612, the connecting rod 612 pushes the sliding block 64 to move, and the sliding block 64 drives the moving plate 65 to move within the guide groove 62. By observing the distance of the scale bar 66 extending from the moving plate 65 through the guide groove 62, it is possible to easily adjust the slitting blade 68 to a suitable position, thus adapting the slitting blade 68 to the tilted film, enabling the slitting blade 68 to slit films at different tilt angles.

[0023] In this embodiment, a support base 2 is fixedly connected to one end of the slitting machine 1, and a mover 3 is installed at the upper end of the support base 2. A winding wheel 4 is installed on the upper side of one end of the slitting machine 1 near the support base 2. A connecting frame 5 is fixedly connected to the upper side of one end of the slitting machine 1 near the winding wheel 4, and the slitting blade 68 is located below the winding wheel 4.

[0024] Specifically, the worker first winds the film around the outside of the winding wheel 4, then pulls the film to move it downwards, thus moving the film to the specified length. Then, the mover 3 is activated, causing the mover 3 to drive the slitting blade 68 to move laterally, thereby causing the slitting blade 68 to cut the film.

[0025] Working principle:

[0026] In use, the worker first winds the film around the outside of the winding wheel 4, then pulls the film downwards to move it to the designated length. At this point, the film tilts. Then, the knob 613 is turned, causing the knob 613 to rotate the connecting rod 612 within the control ring 611. This causes the connecting rod 612 to move within the control ring 611, which in turn pushes the adjusting block 69 through the rotating ring 610. The adjusting block 69 then causes the sliding block 64 to slide within the limiting frame 63, which in turn causes the moving plate 65 to slide within the guide groove 62. This causes the moving plate 65 to move the slitting blade 68. By observing the distance the scale bar 66 extends from the moving plate 65 through the guide groove 62, the movement distance of the slitting blade 68 can be determined, allowing for accurate judgment. The slitting blade 68 is moved a short distance, then pulled to rotate within the blade holder 67, adjusting its angle to suit the film's tilt angle. The mover 3 is then activated, causing it to move the slitting blade 68 laterally, thus slitting the film. Rotating the connecting rod 612 moves the sliding block 64, which in turn moves the moving plate 65 within the guide groove 62. By observing the distance the scale bar 66 extends from the moving plate 65 through the guide groove 62, the slitting blade 68 can be easily adjusted to a suitable position, adapting to the tilted film and enabling it to slit films at different tilt angles.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
