Abstract
Description
Technical Field
[0001] This utility model discloses a film splicing machine, belonging to the technical field of film splicing devices, specifically relating to a film splicing and sealing machine based on chain drive. Background Technology
[0002] The main function of a laminating machine is to accurately bond two film materials together. It is widely used in the manufacture of products such as tapes, labels, and film packaging materials. Traditional laminating machines use a rigid connecting rod in the middle, which cannot rotate axially to release axial force. This causes the connecting rod to loosen after long-term use, resulting in a decrease in the pass rate of the laminating machine. Utility Model Content
[0003] Purpose of the utility model: To provide a film sealing machine based on chain drive to solve the problems mentioned above.
[0004] Technical solution: A film-sealing machine based on chain drive, the film-sealing machine includes: film-sealing jaws, chain, controller, pedal, worktable, cylinder, return spring, rotating mechanism and tooling base;
[0005] The cylinder is fixedly mounted on the workbench base frame, the workbench is fixedly mounted on the workbench surface, the controller is fixedly mounted on the workbench surface, the end of the film-applying jaw is movably mounted on the controller and corresponds to the position of the tooling seat, the rotating mechanism is located in the through hole of the workbench and its end is fixedly connected to the film-applying jaw, and its bottom is fixedly connected to the telescopic rod of the cylinder through the chain, the return spring is sleeved on the rotating mechanism and located on the workbench, and the pedal is located on one side of the workbench.
[0006] In a further embodiment, the pedal and the cylinder are connected to the controller, and the controller controls the cylinder to work as the pedal is operated.
[0007] In a further embodiment, the rotating mechanism includes: a T-shaped shaft, a U-shaped rotating shaft, a flange, a linear retaining ring, and a bearing;
[0008] The top of the T-shaped shaft is fixedly connected to the membrane clamping jaw by a nut, and the bottom is fixedly connected to the flange. The shaft portion of the U-shaped rotating shaft is rotatably installed inside the flange by a bearing, and the U-shaped connecting portion is connected to one end of the chain.
[0009] In a further embodiment, the other end of the chain is connected to the telescopic rod of the cylinder via a connecting seat.
[0010] In a further embodiment, the linear retaining ring is installed at the connection between the U-shaped shaft and the bearing.
[0011] In a further embodiment, the connecting seat and the U-shaped rotating shaft are connected to the chain via pins.
[0012] In a further embodiment, the diameter of the reset spring is larger than the diameter of the through hole in the worktable.
[0013] Beneficial effects: This invention connects the cylinder and the film-applying jaws via a rotating mechanism. The U-shaped shaft can rotate freely with the bearing, the T-shaped shaft is connected to the flange, and the U-shaped shaft and bearing are fixed by a linear snap ring. The T-shaped shaft is connected to the film-applying jaws. When the machine is working, the cylinder retracts rapidly, and the chain experiences axial rotational force due to vibration. The U-shaped shaft releases this axial force through the axial rotation of the bearing. Thus, this invention eliminates the vibration caused by the cylinder's extension and retraction during operation, thereby ensuring the stability and accuracy of the film-applying process.

[0023] A film-sealing machine based on chain drive includes: film-sealing jaws 1, chain 2, controller 3, foot pedal 4, worktable 5, cylinder 6, return spring 7, rotating mechanism 8, and tooling base 9.
[0024] In one embodiment, such as Figures 1 to 4 As shown, the cylinder 6 is fixedly mounted on the workbench base frame, the workbench is fixedly mounted on the workbench 5 surface, the controller 3 is fixedly mounted on the workbench 5 surface, the end of the film-attaching jaw 1 is movably mounted on the controller 3 and corresponds to the position of the tooling base 9, the rotating mechanism 8 is located in the through hole of the workbench 5 and its end is fixedly connected to the film-attaching jaw 1, and its bottom is fixedly connected to the telescopic rod of the cylinder 6 through the chain 2, the return spring 7 is sleeved on the rotating mechanism 8, and the pedal 4 is located on one side of the workbench 5.
[0025] In one embodiment, such as Figures 1 to 4 As shown, the pedal 4 and the cylinder 6 are connected to the controller 3. As the pedal 4 is operated, the controller 3 controls the cylinder 6 to operate.
[0026] In one embodiment, such as Figures 1 to 4 As shown, the rotating mechanism 8 includes: a T-shaped shaft 81, a U-shaped rotating shaft 82, a flange 83, a linear snap ring 84, and a bearing 85;
[0027] The top of the T-shaped shaft 81 is fixedly connected to the membrane clamp 1 by a nut 10, and the bottom is fixedly connected to the flange 83. The shaft part of the U-shaped rotating shaft 82 is rotatably installed in the flange 83 by a bearing 85, and the U-shaped connecting part is connected to one end of the chain 2.
[0028] In one embodiment, such as Figures 1 to 4 As shown, the other end of the chain 2 is connected to the telescopic rod of the cylinder 6 via a connecting seat 86.
[0029] In one embodiment, such as Figures 1 to 4 As shown, the linear snap ring 84 is installed at the connection between the U-shaped rotating shaft 82 and the bearing 85.
[0030] In one embodiment, such as Figures 1 to 4 As shown, the connecting seat 86 and the U-shaped rotating shaft 82 are connected to the chain 2 via a pin 87.
[0031] In one embodiment, such as Figures 1 to 4 As shown, the diameter of the reset spring 7 is larger than the diameter of the through hole in the worktable 5.
[0032] In one embodiment, such as Figures 1 to 4 As shown, place the product to be laminated into the jaws and position it correctly. Depress the foot pedal, and cylinder 6 retracts. The chain 2, connected to the end of cylinder 6, moves downwards together. The upper end of chain 2 is connected to the rotating mechanism 8. The rotating mechanism 8 passes through the middle of the lamination jaws 1 and has a return spring 7. When cylinder 6 retracts, it causes the lamination jaws 1 to close, and the products are laminated together under heat sealing. Releasing the foot pedal 4 opens the lamination jaws 1 under the action of the return spring 7. Remove the product; the lamination machine is now in use.
[0033] In one embodiment, such as Figures 1 to 4 As shown, the U-shaped rotating shaft 82 can rotate freely with the bearing 85. The T-shaped shaft 81 is connected to the flange 83, and the U-shaped rotating shaft 82 and the bearing 85 are fixed by a linear snap ring 84. The T-shaped shaft 81 is connected to the film-attaching jaw 1. When the machine is working, the cylinder 6 retracts quickly, and the chain 2 will have an axial rotational force due to vibration. If the U-shaped rotating shaft 82 cannot rotate axially to release the axial force, the end nut 10 will loosen, causing the film-attaching result to fail.
[0034] Working principle: When this utility model is in operation, the product to be sealed is first placed on the fixed seat (at this time, the cylinder 6 is in the extended state). Then, the operator steps on the foot pedal 4, and the cylinder 6 retracts. The retraction of the telescopic rod drives the chain 2 downward through the connecting seat 86. Thus, the chain 2 drives the U-shaped rotating shaft 82, flange 83 and T-shaped shaft 81 downward. Since the diameter of the return spring 7 is larger than the diameter of the through hole of the worktable 5, the return spring 7 is compressed. At this time, the T-shaped shaft 81 drives the film-sealing jaw 1 to fit against the tooling seat 9 to perform the film-sealing work. After the work is completed, the foot pedal 4 is released, the cylinder 6 extends, the return spring 7 returns to its original position, and thus drives the film-sealing jaw 1 to return to its original position.
[0035] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
