Description

Technical Field

[0001] The utility model relates to the technical field of welding head buffer structures of bag making machines, in particular to a welding head buffer structure of a bag making machine. Background Art

[0002] Bag making machine is a machine for making various plastic packaging bags or other material packaging bags. Its processing range is various sizes, thicknesses and specifications of plastic or other material packaging bags. Generally speaking, plastic packaging bags are the main products. The welding head of the bag making machine will generate impact force when it contacts the bag material, especially when running at high speed. The main function of the buffer structure is to absorb, disperse and slow down the impact force, thereby reducing the impact on the welding head and related parts, reducing the wear and damage of the machine. The buffer structure can play a protective role, slow down the direct contact between the welding head and the bag material, effectively reduce mechanical wear, and extend the service life of the welding head and related parts. Therefore, a bag making machine welding head buffer structure is needed to facilitate the parallel buffering and slowing down of the upward impact of the welding head.

[0003] The welding head buffer device of the bag-making machine disclosed in the publication number CN214056660U includes a bag-making machine body, a bag-making machine support fixedly connected in the middle of the top of the bag-making machine body, a top of one side of the bag-making machine support slidingly connected to one side of the welding head support, a middle of the bottom end of the welding head support fixedly connected to the top of the outer wall of the welding head, and an electric slide fixedly connected to one side of the middle of the top of the bag-making machine body. The utility model drives the transmission belt to roll on the outer wall of the transmission disc through an arc-shaped connecting piece, while the electric slide descends, and the electric slide descends while buffering the transmission disc, so that the transmission disc buffers the welding head fixedly connected to the arc-shaped connecting piece, protecting the welding head from excessive welding of the packaging bag, and solving the problem that the welding head of the existing bag-making machine has no buffer device during welding, and the welding head has a large sliding range, which is easy to cause damage to the bag-making machine, thereby affecting the production efficiency of the bag-making machine.

[0004] However, the welding head buffer device of the bag making machine has the following disadvantages: when the welding head is descending, it is not convenient to maintain parallel buffering to avoid unbalanced force on the welding knife during the downward pressure process, resulting in uneven welding belt of the packaging bag; when the welding head is ascending, it is not convenient to slow down the upward impact to prevent the welding head from rising too quickly, causing damage to the equipment. Utility Model Content

[0005] 1. Technical issues to be resolved

[0006] The technical problem solved by the utility model is to provide a bag making machine welding head buffer structure which is highly practical, can be simply operated and has a relatively simple structure, thereby solving the problem of being inconvenient to maintain parallel buffering and mitigate upward impact raised in the above-mentioned background technology.

[0009] Optionally, the adjustment assembly includes a threaded ring threadedly connected to the surface of the support column, the top of the threaded ring is fixedly connected to a pressure spring, the top of the pressure spring is fixedly connected to a movable ring, the top of the movable ring is fixedly connected to a buffer pad, and the movable ring facilitates the support of the buffer pad to be raised and lowered.

[0010] Optionally, the pull-down assembly includes a fixed joint fixedly connected to the bottom of the fixed block, and a pull-down spring is fixedly connected to the bottom of the fixed joint, so that the pull-down spring is convenient for generating a pull-down force.

[0011] Optionally, the buffer assembly includes a hydraulic rod fixedly connected to the top surface of the pressure plate, a buffer spring is sleeved on the surface of the hydraulic rod, and a base is fixedly connected to the top of the hydraulic rod, and the buffer spring is convenient for mitigating downward impact.

[0012] Optionally, both ends of the pressure plate are threadedly connected with a bubble level, and the top of the support column is fixedly connected with a lower pressure plate, which is convenient for driving the pressure plate.

[0013] Optionally, a welding knife is fixedly connected to the bottom of the pressure plate, and the base facilitates welding with the welding knife.

[0014] Optionally, a support ring is fixedly connected to the bottom of the support column, and the support ring is convenient for increasing the support area.

[0015] (III) Beneficial effects

[0016] The utility model provides a welding head buffer structure for a bag making machine, which has the following beneficial effects:

[0017] 1. The welding head buffer structure of the bag making machine adjusts the settings of the components and the bubble level. When it is necessary to keep the pressure plate parallel to the buffer, the bubble level is used for measurement. When the pressure plate is tested downward, the threaded collar is rotated to make the threaded collar rotate on the surface of the support column, thereby driving the pressure spring to rise and fall. The four groups of pressure springs are adjusted to be in the same horizontal position, so as to achieve the effect of stable buffering when the welding knife is pressed down, avoid unbalanced force on the welding knife during the pressing process, cause unevenness of the welding belt of the packaging bag, and improve the production quality of the packaging bag.

[0018] 2. The buffer structure of the welding head of the bag making machine is provided with a pull-down component. When the pressure plate moves downward, the pressure plate squeezes the pressure spring for buffering. The pressure spring deforms to generate a recoil force. When the pressure plate moves upward, the recoil force drives the pressure plate to rise rapidly. The tension of the pull-down spring is utilized to pull the pressure plate on the fixed joint, thereby achieving the effect of slowing down the upward impact of the pressure plate, preventing the pressure plate from rising too fast to cause equipment damage, and extending the service life of the bag making machine.
