Description

Technical Field

[0001] This utility model relates to the field of plastic bag making machine technology, and in particular to a feeding auxiliary device for a plastic bag making machine. Background Technology

[0002] A bag-making machine is a machine that produces various plastic or other material packaging bags. Its processing range includes packaging bags of various sizes, thicknesses, and specifications made of plastic or other materials, with plastic packaging bags being its main product.

[0003] Currently, bag-making machines are equipped with plastic bag roll devices at their feed end to supply raw materials for the bags. During the bag-making process, the plastic bag roll device provides raw materials to the machine. However, when the raw materials in the plastic bag roll device are used up, it is necessary to replace the plastic bag roll and connect the raw materials on the newly replaced plastic bag roll to the raw materials on the bag-making machine so that the machine can continue to produce plastic bags.

[0004] In the process of connecting the raw materials on the plastic bag roll to the raw materials on the bag-making machine, adhesive tape is generally used for bonding. At least two operators are required to align the raw materials on the plastic bag roll with the raw materials on the bag-making machine, and then another operator uses adhesive tape to seal the connection. Because the raw materials are relatively soft and easily move, and without auxiliary tools, accurate bonding is difficult, resulting in low efficiency and room for improvement. Utility Model Content

[0005] The purpose of this invention is to provide a feeding auxiliary device for a plastic bag making machine, which can automatically complete the docking of plastic bags, resulting in stable bonding and higher work efficiency.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a feeding auxiliary device for a plastic bag making machine, comprising a base and a bag making machine body installed on the top left side of the base, wherein the base is provided with an unwinding feeding structure and an adhesive mechanism on the right side of the bag making machine body, the unwinding feeding structure comprising a bracket fixed to the top right side of the base, an unwinding component and a first electric push rod located above the unwinding component are installed on the bracket, a movable frame is installed at the output end of the electric push rod, two symmetrical movable plates and an adjusting component for adjusting the distance between the two movable plates are installed on the inner side of the movable frame, and a bag clamping structure is installed on the inner side of the movable plate.

[0007] By adopting the above technical solution, the end of the new packaging bag to be connected is placed on one side of the bonding mechanism. The distance between the two moving plates is adjusted by the adjusting component to correspond with the packaging bag specifications on the unwinding component. Then, the two sides of the packaging bag to be bonded are clamped by the clamping structure, and the bag is conveyed to the bonding mechanism by the electric push rod to correspond with the end of the new packaging bag. The bonding mechanism automatically bonds them together, which not only greatly saves labor, but also increases work efficiency and improves the stability of the bonded packaging bag, making it easier for subsequent processing operations.

[0008] A further feature of this invention is that the bag clamping structure includes a fixing plate fixed to the inner side of the moving plate and a second electric push rod located below the moving plate, wherein a push plate is installed on the output end of the second electric push rod.

[0009] By adopting the above technical solution, one side of the end of the packaging bag is placed under the fixed plate, and the push plate is pushed up by the second electric push rod to clamp the end of the packaging bag, so that it can be stably conveyed to the bonding mechanism.

[0010] A further feature of this invention is that the adjusting component includes a first motor mounted on one side of the movable frame, a bidirectional lead screw adapted to the threads of the two movable plates is mounted on the output end of the first motor, and a fixing rod adapted to the sliding of the two movable plates is also mounted on the movable frame.

[0011] By adopting the above technical solution, the first motor drives the bidirectional lead screw to rotate, and the distance between the two moving plates can be adjusted under the sliding guidance of the guide rod, so that it corresponds to the positions of the two ends of the packaging bag.

[0012] A further feature of this invention is that the unwinding component includes a second motor mounted on one side of the support, and an unwinding roller is mounted on the output end of the second motor.

[0013] By adopting the above technical solution, the unwinding roller is driven by the second motor to unwind the packaging bag, which facilitates bonding with the new packaging bag.

[0014] A further feature of this invention is that the bonding mechanism includes a U-shaped frame fixed to the top of the base and located between the bag-making machine body and the support frame, a support platform is installed on the inner side of the U-shaped frame, and a hot pressing component is provided at the upper end of the support platform.

[0015] By adopting the above technical solution, after the positions of the packaging bags on both sides are aligned, the ends are hot-pressed by a hot-pressing component to achieve stable adhesion.

[0016] A further feature of this invention is that the hot pressing component includes a third electric push rod installed on the upper end of the U-shaped frame, a pressure plate installed at the output end of the third electric push rod, a hot pressing strip installed on the right side of the bottom of the pressure plate, and a limiting component installed on the left side.

[0017] By adopting the above technical solution, the pressure plate is pushed down by the third electric push rod, so that the heat-pressing strip heats and presses the joint of the two packaging bags together, thereby bonding them together.

[0018] A further feature of this invention is that the limiting member includes a pressure strip movably disposed below the pressure plate and an elastic member that pushes the pressure strip down.

[0019] By adopting the above technical solution, when the end of the new packaging bag is placed on the support platform, the pressure strip moves down through the elastic element, which can initially limit the end face of the packaging bag, prevent the packaging bag from running around before bonding, make the bonding more precise, and improve the stability of the packaging bag.

[0020] A further feature of this invention is that the elastic element includes two guide rods fixedly installed on the top of the pressure bar and movably connected to the pressure plate, each guide rod being fitted with a spring, and a baffle plate being installed at the top between the two guide rods.

[0021] By adopting the above technical solution, the compression and rebound of the spring pushes the pressure strip down, thus limiting one end of the new bag.

[0022] The beneficial effects of this utility model are: 1. In this utility model, before bonding, the end of the new packaging bag is placed on the support platform. The pressure plate is pushed down by the third electric push rod, so that the pressure strip is close to the end of the packaging bag. The spring is compressed and rebounded, pushing the pressure strip down, so that one end of the new bag is limited, so that there will be no deviation problem during subsequent bonding. The bonding accuracy is higher and the stability of the packaging bag is better. 2. This utility model adjusts the distance between the two moving plates by adjusting the adjustment component to correspond to the packaging bag specifications on the unwinding component. Then, the two sides of the packaging bag that need to be glued are clamped by the clamping structure, and the bag is conveyed to the bonding mechanism by the electric push rod to correspond to the end of the new packaging bag. The bonding mechanism automatically glues the bag together, which not only greatly saves labor but also improves work efficiency. Attached Figure Description
