Compared with plastic woven bags, its raw material ratio is unique, the performance is superior and environmentally friendly, the equipment is advanced, and it is easy to recycle. In the processing of heavy film packaging bags, in order to improve the appearance of the finished product, the surface of the heavy film packaging bags is usually embossed with an embossing structure. The embossing machine is used to emboss, bubble, wrinkle, and trademark on various fabrics. It can also emboss trademarks on non-woven fabrics, coatings, artificial leather, paper, and aluminum plates, simulate leather patterns, and various types of patterns and patterns. However, it still has the following disadvantages in actual use:

[0003] The utility model with the publication number CN219055323U discloses an anti-slip embossing forming mechanism for FFS heavy film packaging bags, wherein a middle plate is provided in the molding cavity, a first guide roller group and a second guide roller group are respectively provided on one side of the molding cavity and the middle plate, a cold air blower is installed on the top of the molding cavity, an output end of the cold air blower is connected to a cold air chamber through a cold air inlet, an air duct is provided in the cold air chamber, a partition is fixed in the middle position of the top of the air duct, and the middle position of the cold air chamber is an air outlet, and the embossing structure usually embosses a designated pattern through an embossing roller, but since the heavy film packaging bag often needs to be embossed at a certain temperature, and the heavy film packaging bag itself often has a certain elasticity, and the contact time between the embossing roller and the heavy film packaging bag is short, the actual embossed pattern may be shallow due to insufficient embossing time and temperature, thereby reducing the aesthetics of the finished product;

[0004] During the embossing process, the heated heavy film packaging bags are often prone to deformation. When the heavy film packaging has not been cooled after heating, it will be subjected to a certain tension during the movement, which may cause the heavy film packaging bags to deform and reduce product quality. Utility Model Content

[0005] The utility model aims to provide an anti-slip embossing structure for heavy film packaging bags. Through the first support frame and the second support frame, the anti-slip embossing structure solves the problem that during the embossing process of the heavy film packaging bag, the contact time between the embossing roller and the surface of the heavy film packaging bag is short, which may cause the actual embossed pattern to be shallow due to insufficient embossing time and temperature. When the packaging bag is heated but not cooled down, it will be subjected to a certain tension during the movement, which may cause the heavy film packaging bag to deform.

[0006] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0007] The utility model is a non-slip embossing structure for a heavy film packaging bag, comprising a first support frame and a second support frame, wherein a first conveyor belt is rotatably clamped inside the first support frame, a heat dissipation frame is penetrated and clamped on one side of the first support frame, a second support frame is arranged outside the first support frame, a second conveyor belt is rotatably clamped inside the second support frame, and a plurality of convex embossed plates are clamped on the outer peripheral surface of the second conveyor belt;

[0008] The rotation of the first conveyor belt can further drive the heavy film packaging bag to move, thereby avoiding slipping during the embossing process caused by the large friction between the heavy film packaging bag and the convex embossing plate. The heat dissipation rack can cool the heavy film packaging bag after high-temperature embossing, thereby avoiding deformation of the heavy film packaging bag due to tension after leaving the embossing structure. The rotation of the second conveyor belt can drive multiple convex embossing plates to move, so that the convex embossing plates and the heavy film packaging bag move synchronously, thereby extending the heating, embossing and cooling time of the heavy film packaging bag, and ensuring the embossing efficiency.

[0009] Furthermore, a first rotating roller is clamped on the inner side of the first support frame, the first conveyor belt is attached to the outer peripheral surface of the first rotating roller, a first rotating motor is clamped through one side of the first support frame, and the first rotating motor is drivingly connected to the first rotating roller;

[0010] The first conveyor belt can be driven to rotate by the first rotating motor, which further drives the movement of the heavy film packaging bag, thereby preventing the heavy film packaging bag and the convex embossing plate from slipping during the embossing process due to the large friction between the heavy film packaging bag and the convex embossing plate.

[0011] Furthermore, a heat insulation board is clamped and fixed on the inner side of the first support frame, a heating plate is clamped and fixed on one side of the first support frame, a first heat-resistant rubber pad is clamped and fixed on the top of the heating plate, and the first heat-resistant rubber pad is attached to the inner top of the first conveyor belt;

[0012] The heavy film packaging bag can be heated by the heating plate to ensure the embossing efficiency, and the heat insulation board can prevent a large amount of heat from being lost through the heat dissipation rack.

[0013] Furthermore, a second heat-resistant rubber pad is clamped and fixed on the top of the heat dissipation frame, a cooling fan is clamped on one side of the first support frame, the cooling fan is connected to the heat dissipation frame, the heat dissipation frame is located on the other side of the heat insulation plate relative to the heating plate, and the second heat-resistant rubber pad is attached to the top of the first conveyor belt;

[0014] After the embossing is completed, the cooling fan drives the air flow, which can quickly cool down the heat sink, and further cool down the heavy film packaging bag, so as to avoid deformation of the heavy film packaging bag due to tension after leaving the embossing structure.

[0015] Furthermore, a second rotating roller is rotatably connected in the second support frame, the second rotating roller is attached to the inner wall of the second conveyor belt, a second rotating motor is penetrated and connected to one side of the second support frame, and the second rotating motor is drivingly connected to the second rotating roller;

[0016] The second conveyor belt can be driven to rotate by the second rotating motor, which further drives all the convex embossing plates to move, so that the convex embossing plates and the heavy film packaging bags move synchronously, extending the heating, embossing and cooling time of the heavy film packaging bags, and ensuring the embossing efficiency.

[0017] Furthermore, a limiting pressure plate is fixedly connected to the inner side of the second support frame, the limiting pressure plate is attached to the inner bottom of the second conveyor belt, and the convex embossed plate is suspended from the top of the first conveyor belt;

[0018] The second conveyor belt can be limited by the limiting pressure plate to ensure that the pressure of the convex embossing plate on the heavy film packaging bag is stable and the embossing efficiency is guaranteed.

[0019] The utility model has the following beneficial effects:

[0020] The utility model solves the problem that the embossing structure usually embosses a designated pattern through an embossing roller by setting a first support frame and a second support frame, but since the heavy film packaging bags often need to be embossed at a certain temperature, and the heavy film packaging bags themselves often have a certain elasticity, and the contact time between the embossing roller and the heavy film packaging bags is relatively short, the actual embossed pattern may be shallow due to insufficient embossing time and temperature, thereby reducing the aesthetics of the finished product. The second support frame drives the second conveyor belt to rotate, which further drives the synchronous movement of the convex embossing plate and the heavy film packaging bag, thereby extending the heating and embossing time of the heavy film packaging bag without affecting the moving speed of the heavy film packaging bag, thereby ensuring the embossing efficiency.

[0021] The utility model solves the problem that during the embossing process, the heated heavy film packaging bag is often prone to deformation, and when the heavy film packaging has not been cooled after heating, it will be subjected to a certain tension during the movement, which may cause the heavy film packaging bag to deform and reduce product quality. After the heavy film packaging bag enters between the first conveyor belt and the second conveyor belt, the heavy film packaging bag moves synchronously with the first conveyor belt and the second conveyor belt, and after being heated and embossed by the heating plate, the heavy film packaging bag is cooled by the heat dissipation rack while still maintaining synchronous movement. The bag is relatively still, thereby preventing the high-temperature heavy film packaging bag from being deformed due to tension after leaving the embossing roller. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] After the heavy film packaging bag processed in the previous step enters between the first conveyor belt 101 and the second conveyor belt 204, the downward rotating convex embossing plate 201 embosses the heavy film packaging bag, and the heavy film packaging bag is heated by the heating plate 105. The convex embossing plate 201 and the heavy film packaging bag are moved synchronously by the rotation of the first conveyor belt 101 and the second conveyor belt 204 to extend the embossing time. After the heavy film packaging bag moves to the top of the heat dissipation rack 108, the heat dissipation rack 108 cools the heavy film packaging bag after high-temperature embossing. After cooling for a certain period of time, the embossed heavy film packaging bag is separated from between the first conveyor belt 101 and the second conveyor belt 204 and proceeds to the next step of processing.
