DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0036] like Figures 1 to 5 The dynamic welding device for the film material production line shown is arranged between the transverse stacking component 00 and the cutting component 01 along the conveying direction of the film material, and includes: a moving seat 1, a first welding head 2, a second welding head 3 and a linear driving component 4; the first welding head 2 and the second welding head 3 are relatively arranged on the moving seat 1, and are located on both sides of the film material; the linear driving component 4 is arranged at one end of the second welding head 3 away from the first welding head 2, and is used to drive the second welding head 3 to move toward the first welding head 2, and butt weld the transversely stacked film material to form a welding belt; wherein, a driving component 5 is arranged on the side of the moving seat 1 located at the first welding head 2, and is used to drive the moving seat 1 to move synchronously with the film material.

[0037] The laminated film material passes between the first welding head 2 and the second welding head 3, and after being transmitted to the set distance, the linear drive 4 is started to make the second welding head 3 approach the first welding head 2 and perform butt welding on both sides of the film material. At the same time, the driving component 5 drives the moving seat 1 to move synchronously with the film material at the same speed until the welding is completed. The second welding head 3 gradually moves away from the first welding head 2, and the moving seat 1 stops moving. At this time, the film material is in a continuous transmission state, and the moving seat 1 returns to the initial position. The welding band formed by butt welding on the film material is cut off by the cutting component 01, and the two synchronous belts symmetrically arranged at the conveying end of the cutting component 01 deliver the cut product, and the conveying speed of the synchronous belt is greater than the moving speed of the moving seat 1, so as to pull off the incompletely cut part to form a separate product. After the cutting component 01 completes the cutting of the film material, the two cutting rollers continue to rotate to feed the end of the film material into the two synchronous belts, and the above steps are repeated to achieve continuous production of products. The utility model can ensure effective control of the quality of the film material during the welding process through the relative arrangement of the first welding head 2 and the second welding head 3, and the driving component 5 drives the moving seat 1 to move synchronously to realize dynamic welding of the film material, thereby ensuring the welding time and reducing the production downtime waiting time, thereby improving the overall production efficiency of the product.

[0038] The movable seat 1 in the utility model includes a base plate 11, and a first mounting seat 12 and a second mounting seat 13 arranged on the base plate 11; the first welding head 2 is fixed on the first mounting seat 12, and the second welding head 3 is fixed on the second mounting seat 13; and a plurality of support shafts 14 are arranged between the first mounting seat 12 and the second mounting seat 13.

[0039] Specifically, the base plate 11 serves as the foundation of the movable seat 1 and provides a solid supporting platform, while the first mounting seat 12 and the second mounting seat 13 located on the base plate 11 fix the welding head, thereby ensuring the precise position of the welding head, and forming a butt welding area between the two mounting seats through a plurality of supporting shafts 14 for the film material to pass through, which helps to disperse heat and effectively ensure the overall stability of the movable seat 1.

[0040] Since the first welding head 2 is used as a reference during the welding process, the second welding head 3 moves toward the first welding head 2 to form a butt weld on the membrane material, in order to ensure the stability of the tension force of the membrane material during butt welding, preferably, the first mounting seat 12 includes a first fixed plate 121 arranged perpendicular to the bottom plate 11, and an adjustment plate 122 arranged on the side of the fixed plate away from the second mounting seat 13; the adjustment plate 122 is fixed to the fixed plate by an adjustment rod, and the first welding head 2 is fixed on the adjustment plate 122. By adjusting the first welding head 2, the welding surface of the first welding head 2 is close to the membrane material, and when the second welding head 3 pushes the membrane material to the first welding head 2 to form a butt weld, the bending phenomenon of the membrane material is avoided, and the welding quality of the membrane material is guaranteed.

[0041] The second mounting seat 13 includes a second fixed plate 131, and a sliding assembly 132 arranged on the side of the second fixed plate 131 facing the second welding head 3; the second welding head 3 is fixed on the sliding assembly 132, and the linear drive member 4 is arranged on the side of the second fixed plate 131 away from the second welding head 3, and its driving rod passes through the second fixed plate 131 and is fixedly connected to the sliding assembly 132. Preferably, the linear drive member 4 adopts a cylinder structure, but is not limited to this structure, the second fixed plate 131 is fixed on the bottom plate 11, and the sliding assembly 132 is fixed on the second fixed plate 131, and one end extending out of the second fixed plate 131 is connected to the second welding head 3, which can drive the second welding head 3 to move in the direction close to or away from the first welding head 2, so as to achieve butt welding of the membrane material. Specifically, in order to ensure the stability of the two welding heads, the sliding assembly 132 includes a sliding plate 1321 parallel to the second fixed plate 131, and two guide shafts 1322 arranged on the side of the sliding plate 1321 facing the second fixed plate 131; a sliding hole is provided on the second fixed plate 131 corresponding to the guide shaft 1322, and a sliding sleeve 1323 is provided in the sliding hole. Through the two guide shafts 1322 moving in the sliding sleeve 1323 in the sliding hole, the sliding plate 1321 can maintain stable sliding parallel to the second fixed plate 131, thereby ensuring the linearity and accuracy of the second welding head 3 during the movement, which is conducive to improving the accuracy and quality of welding. In addition, a heat insulation plate 6 is provided between the sliding plate 1321 and the second welding head 3. The heat insulation plate 6 can effectively isolate these high temperatures and prevent them from being transmitted to the sliding plate 1321 or other components.

[0042] In the preferred embodiment, the welding surface of the second welding head 3 is provided with a plurality of tooth-shaped grooves (not shown in the figure). Due to the dispersed design of the tooth-shaped grooves, the heat and pressure generated during welding can be more evenly distributed on the film material, reducing the deformation of the film material caused by local overheating or excessive pressure, and the tooth-shaped grooves increase the contact area between the welding surface and the film material, which helps to form a stronger and more uniform weld during the welding process, thereby improving the welding quality. In addition, a Teflon coating is provided on the welding surface formed by the plurality of tooth-shaped grooves. Under high temperature and high pressure welding conditions, the Teflon coating on the tooth-shaped grooves can also effectively prevent the film material or other welding materials from adhering to the welding head. This helps to keep the welding head clean and reduce the frequency of cleaning and maintenance.

[0043] In the preferred embodiment of the utility model, the driving assembly 5 includes a driving motor 51, a pulley group 52 horizontally arranged along the transmission direction, and a connecting plate 53 for connecting the pulley group 52 and the moving seat 1; the pulley group 52 includes two pulleys and a conveyor belt wrapped around the two pulleys, and the connecting plate 53 is fixed on the conveyor belt, and drives the moving seat 1 to reciprocate along a direction parallel to the transmission direction. By driving the pulley group 52 by the driving motor 51, the conveyor belt can smoothly drive the connecting plate 53 and the moving seat 1 connected thereto to reciprocate. This movement mode is smoother than directly driving the moving seat 1 by the motor, and reduces the impact and vibration during the movement. In the design process of the connecting plate 53, preferably, the connecting plate 53 includes an upper clamping plate and a lower clamping plate; the lower clamping plate is fixed on one side of the moving seat 1, and the upper clamping plate is fixed above the lower clamping plate to clamp the belt. The upper clamping plate and the lower clamping plate work together to clamp the belt tightly in the middle, ensuring a firm connection between the moving seat 1 and the belt; and when the belt needs to be replaced or repaired, the belt can be easily removed or installed by simply loosening the upper clamping plate, reducing the complexity and time cost of maintenance work.
