Description

Technical Field

[0001] This utility model relates to a packaging bag processing equipment, and more particularly to a packaging bag punching device. Background Technology

[0002] Packaging bags are flexible containers used to package various items, playing a vital role in the circulation, storage, and sale of goods. They not only protect goods from external environmental factors (such as moisture, dust, and impacts), but also, through printing and design, serve to promote products and attract consumers.

[0003] In the production and processing of packaging bags, punching is required, such as punching out various functional holes like rope holes and handle holes. Existing punching equipment mainly consists of a frame, a slide mounted on the frame, a lower die mounted on the slide, a feeding assembly that drives the slide, a clamping assembly mounted on the slide, a punching head mounted on the frame and above the slide, and a drive assembly that drives the punching head. The feeding assembly, clamping assembly, and drive assembly all require driving components to move, which keeps the production cost of existing punching equipment high. Furthermore, the increased number of driving components undoubtedly significantly increases the probability of malfunctions, thereby reducing the reliability of the punching equipment. Utility Model Content

[0004] The purpose of this invention is to provide a packaging bag punching device that has lower cost, lower failure rate, and higher reliability, thereby improving the processing efficiency of packaging bags.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a packaging bag punching device, including a frame, a slide mounted on the frame, a lower die mounted on the slide, a clamping component mounted on the lower die and used to clamp the packaging bag, a punching head mounted on the frame, and a driving component for driving the punching head to move. The slide has a working position and a non-working position, and the punching head has a punching position and a non-punching position for punching in conjunction with the lower die. A first linkage component is provided between the punching head and the slide to drive the slide to move. When the slide is in the working position, the punching head is in the punching position. The clamping component has a clamping state and a non-clamping state. A second linkage component is provided between the clamping component and the frame to control the switching of the clamping component between the clamping state and the non-clamping state. When the punching head is in the punching position, the clamping component is in the clamping state.

[0006] By adopting the above technical solution, the packaging bag to be processed is placed above the lower die. The driving component drives the punching head to switch from a non-punching position to a punching position. During the switching process, the first and second linkage components drive the slide and clamping components to move, switching the slide from a non-working position to a working position and the clamping component from a non-clamping state to a clamping state. During the switch, the clamping component first switches from a non-clamping state to a clamping state to clamp and fix the packaging bag above the lower die. Then, the lower die, in conjunction with the punching head, performs the punching and perforating operation on the packaging bag. This linkage structure reduces the number of driving components, resulting in a lower cost, lower failure rate, and higher reliability for the punching device, thereby improving the processing efficiency of the packaging bag.

[0007] The first linkage component is further configured as follows: a reversing arm rotatably mounted on the frame, a first connecting arm that moves with the punching head and abuts against one end of the reversing arm to drive the reversing arm to rotate, a first reset spring for resetting the reversing arm, and a first linkage assembly formed between the slide and the reversing arm.

[0008] By adopting the above technical solution, the punching head drives the first connecting arm to move towards the reversing arm. The first connecting arm abuts against one end of the reversing arm, thereby driving the reversing arm to rotate. Then, in conjunction with the first linkage component, it drives the slide to move, thus achieving the purpose of reversing linkage. When the reversing arm loses the force applied by the first connecting arm, the first return spring performs a reset operation, thereby controlling the slide to achieve reciprocating motion.

[0009] The first linkage component is further configured to include a linkage stroke hole disposed at the other end of the reversing arm and a linkage rod that moves with the slide and extends into the linkage stroke hole.

[0010] By adopting the above technical solution, the linkage between the slide and the reversing arm is achieved through the linkage stroke hole and the linkage rod.

[0011] A further configuration is provided: the reversing arm is rotatably equipped with a roller that abuts against the first connecting arm at one end.

[0012] By adopting the above technical solution, the rollers transform the sliding friction between the first connecting arm and the reversing arm into rolling friction, thereby reducing mutual wear between the two, extending the service life of the components, and improving the precision of the linkage structure.

[0013] The clamping assembly is further configured such that: the clamping assembly includes a pressure plate hinged to the lower mold and a positioning spring connected to the pressure plate; when the positioning spring is in the initial state, the clamping assembly is in a non-clamping state.

[0014] By adopting the above technical solution, the pressure plate, together with the positioning spring, can switch between the pressure plate in the pressing state and the non-pressing state. The packaging bag placed above the lower mold is located below the pressure plate, so that the rotating pressure plate can perform the pressing operation on the packaging bag.

[0015] The second linkage component is further configured such that: the second linkage component includes a second connecting arm disposed on the frame and a linkage inclined surface formed on the second connecting arm; when the positioning spring is in the initial state, the pressure plate is tilted on the side opposite to the second connecting arm, and the movement path of the pressure plate intersects with the linkage inclined surface.

[0016] By adopting the above technical solution, during the process of the slide moving the pressure plate from the non-working position to the working position, the pressure plate comes into contact with the linkage inclined surface, and the linkage inclined surface resists the pressure plate to rotate downward, thereby pressing the packaging bag located on the lower mold.

[0017] The slide block is further configured such that an adjusting block is slidably disposed on the slide block along the direction of movement of the slide block, a locking structure is provided between the adjusting block and the slide block, and the linkage rod is disposed on the adjusting block.

[0018] By adopting the above technical solution, when the first linkage component has a linkage fit error, the position of the linkage rod can be adjusted by locking the structural fit adjustment block, thereby ensuring the linkage accuracy of the first linkage component.

[0019] The locking structure is further configured to include an adjustment hole disposed in the adjustment block and a locking bolt passing through the adjustment hole and threadedly connected to the slide.

[0020] By adopting the above technical solution, the position of the adjusting block can be conveniently adjusted by using the locking bolt and adjusting hole structure.

[0021] In summary, this utility model has the following advantages: it has lower cost, lower failure rate, and higher reliability, thereby improving the processing efficiency of packaging bags. Attached Figure Description
