Description

Technical Field

[0001] The utility model relates to the technical field of packaging bag shaping, in particular to a plastic packaging bag cutting and shaping device. Background Art

[0002] Plastic packaging bags are made of plastic as raw materials and are used to produce various daily necessities. They are widely used in daily life and industrial production, but this temporary convenience brings long-term harm. Commonly used plastic packaging bags are mostly made of polyethylene film, which is non-toxic and can be used to hold food.

[0003] Plastic packaging bags are cut and formed, and then conveyed out by a conveyor belt. However, when packaging plastic packaging bags, multiple plastic packaging bags are generally stacked and then conveyed into the packaging equipment. However, it is not easy to align the plastic packaging bags during the stacking process. For this reason, we propose a plastic packaging bag cutting and shaping device. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the utility model provides a plastic packaging bag cutting and shaping device.

[0005] The utility model provides the following technical solutions: a plastic packaging bag slitting and shaping device, comprising a conveyor belt for conveying slit plastic packaging bags and a conveyor belt for conveying stacked and shaped plastic packaging bags, wherein the conveyor belt and the conveyor belt are connected by an arc-shaped baffle;

[0006] A bracket is installed on the conveyor belt and the frame of the conveyor belt, two linear modules are installed on the bracket, and the sliders of the two linear modules are provided with a stacking structure for stacking the packaging bags on the conveyor belt on the conveyor belt;

[0007] The stacking structure comprises a frame and a cylinder mounted on the frame, a support beam is mounted on the output shaft of the cylinder, and a plurality of pneumatic suction nozzles for adsorbing plastic packaging bags are mounted on the support beam.

[0008] Preferably, the arc-shaped baffle is higher than the conveyor belt and the transmission belt.

[0009] Preferably, when the stacking structure transfers the packaging bags on the conveyor belt to the conveyor belt, the end of the packaging bags is close to the arc-shaped baffle.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] The plastic packaging bag slitting and shaping device has a conveyor belt that transmits the slitting plastic packaging bags, and a pneumatic suction nozzle on the stacking structure absorbs one end of the plastic packaging bag and transfers it to the conveyor belt. The operation is then repeated to neatly stack multiple layers of packaging bags on the conveyor belt. The arc-shaped baffle plate allows the ends of the packaging bags to touch when the packaging bags are transferred to avoid folding. When the packaging bags on the conveyor belt are stacked to a suitable height, the conveyor belt runs to move the stacked packaging bags forward a distance. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 2 This is a schematic diagram of the stacking structure of the utility model.

[0014] In the figure: 1. conveyor belt; 2. conveyor belt; 3. arc baffle; 4. bracket; 5. linear module; 6. stacking structure; 61. frame; 62. cylinder; 63. support beam; 64. pneumatic suction nozzle. DETAILED DESCRIPTION

[0015] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. In order to keep the following description of the embodiments of the present disclosure clear and concise, the present disclosure omits detailed descriptions of known functions and known components to avoid unnecessary confusion of the concepts of the present invention.

[0016] See also Figure 1-2 A plastic packaging bag slitting and shaping device comprises a conveyor belt 1 for conveying slit plastic packaging bags and a conveyor belt 2 for conveying stacked and shaped plastic packaging bags, wherein the conveyor belt 1 and the conveyor belt 2 are connected by an arc-shaped baffle plate 3, and the arc-shaped baffle plate 3 is higher than the conveyor belt 1 and the conveyor belt 2. When the stacking structure 6 transfers the packaging bags on the conveyor belt 1 to the conveyor belt 2, since the end of the packaging bag is close to the arc-shaped baffle plate 3, during the process of transferring the packaging bag to the conveyor belt 2, the end of the packaging bag will pass through the arc-shaped baffle plate 3 and finally slide off the arc-shaped baffle plate 3, so that during the transfer of the packaging bag, the packaging bag will not contact the end of the stacked packaging bag, and the end of the stacked packaging bag will not be folded.

[0017] A bracket 4 is installed on the frame of the conveyor belt 1 and the conveyor belt 2, and two linear modules 5 are installed on the bracket 4. The sliders of the two linear modules 5 are provided with a stacking structure 6 for stacking the packaging bags on the conveyor belt 1 on the conveyor belt 2. The packaging bags on the conveyor belt 1 are picked up by the stacking structure 6, and under the movement of the linear module 5, the stacking structure 6 drives the packaging bags to move to the conveyor belt 2, and the transfer is performed in this way.

[0018] The stacking structure 6 includes a frame 61 and a cylinder 62 installed on the frame 61, a support beam 63 is installed on the output shaft of the cylinder 62, and a plurality of pneumatic suction nozzles 64 for adsorbing plastic packaging bags are installed on the support beam 63. The cylinder 62 pushes the support beam 63 to move downward, so that the pneumatic suction nozzles 64 on the support beam 63 move downward and contact with the packaging bags on the conveyor belt 1 and pick them up. Then, the cylinder 62 drives the support beam 63 to return to its original position and moves under the drive of the linear module 5, so that the cylinder 62 drives the packaging bags on the support beam 63 to be transferred to the conveyor belt 2, and then the linear module 5 repeatedly drives the stacking structure 6 to stack the packaging bags on the conveyor belt 2.

[0019] The above embodiments are only exemplary embodiments of the present invention and are not intended to limit the present invention. The protection scope of the present invention is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the essence and protection scope of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present invention.
