Description

Technical Field

[0001] The utility model relates to the technical field of film stretching, in particular to a closing clip device for a stretching film. Background Art

[0002] In the technical field of film processing such as battery diaphragms, a stretching film production line generally clamps both ends of a film through a chain clip device, and then drives the film through each equipment process. During the process of the chain clip, the chain clip remains in a closed state to realize clamping and stretching of the film; after the film stretching is completed and enters the next process, the chain clip returns, and during the return process, the chain clip remains in an open state. When the chain clip changes from the return stroke to the forward stroke, a closing clip device is required to ensure that the chain clip automatically closes and re-clamps the film.

[0003] The traditional closing clip device only adopts a set of closing clip plate structures. The closing clip plate has dry friction with the tail of the chain clip. Long-term operation will cause wear of the closing clip plate or the chain clip. The worn powder enters the film and affects the film quality. Serious wear will cause the structure to fail, unable to realize clamping and stretching of the film, and affect the film processing efficiency and quality.

[0004] Therefore, we have designed a new type of closing clip device. The chain clip is closed by the rolling friction between the closing clip wheel and the tail of the chain clip. The chain clip that has not been closed by the closing clip wheel is then secondarily closed through a forced closing clip plate, which can effectively ensure that all chain clips are closed, reduce equipment failures, and at the same time reduce the friction powder generated by friction from entering the film, ensuring the processing quality of the film. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a closing clip device for a stretching film to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A closing clip device for a stretching film includes a main frame body. A plurality of chain clips are movably arranged on the main frame body. A closing clip wheel located at the forward stroke of the chain clip is rotatably arranged on the main frame body for closing the chain clip. A forced closing clip plate located behind the closing clip wheel is also arranged on the main frame body for closing the chain clip that has not been closed after passing through the closing clip wheel.

[0008] As a further preferred solution of the utility model: The horizontal distance between the closing clip wheel and the forced closing clip plate and the chain clip is adjustable.

[0009] As a further preferred solution of the utility model: A cylinder is fixedly arranged at the upper end of the main frame body. The output end of the cylinder is connected with a mounting plate. A front connecting plate and a rear connecting plate are arranged on the mounting plate. The closing clip wheel is rotatably arranged on the front connecting plate, and the forced closing clip plate is fixedly arranged on the rear connecting plate.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] The closing clip device realizes the closing of the chain clip through the rolling friction between the closing clip wheel and the tail of the chain clip at the chain clip advancing process. For the chain clip that has not been closed after passing through the closing clip wheel, secondary closing can be achieved through the forced closing clip plate. Through the combined design of a set of closing clip wheels and a set of forced closing clip plates, a double insurance for the closing of the chain clip is realized, which can ensure that all chain clips can be closed, reduce equipment failures, and at the same time effectively reduce the entry of friction powder generated by friction into the film, improving the film processing quality. The design is scientific and reasonable, and has strong practicability. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. Embodiment 1

[0020] Please refer to Figures 1-6, this embodiment provides a closing clamp device for a stretching film, including a main frame body 1. A plurality of chain clamps 2 are movably arranged on the main frame body 1. Specifically, a guide rail 12 is arranged on the main frame body 1, and the chain clamps 2 are installed on the guide rail 12 and move along the guide rail 12. It should be noted that the above structure is a conventional structure in the art and will not be elaborated in this application.

[0021] Among them, the structure of the chain clamp 2 is as Figure 5 and Figure 6 shown, mainly composed of a connecting frame 9, a movable clamping plate 10, and a force-bearing handle 11. Figure 5 is the state when the chain clamp 2 is opened. The movable clamping plate 10 and the force-bearing handle 11 are integrally designed, and the middle part thereof is rotatably connected to the connecting frame 9. The force-bearing handle 11 is inclined outward. When the force-bearing handle 11 is forced to rotate clockwise, the movable clamping plate 10 also rotates clockwise, and the chain clamp 2 is in the Figure 6 closed state shown in. This chain clamp 2 is an existing mature structure and will not be elaborated in this application.

[0022] In order to enable the chain clamp 2 to be effectively closed at the advancing position, a closing clamp wheel 7 located at the advancing position of the chain clamp 2 is rotatably arranged on the main frame body 1 for closing the chain clamp 2. A forced closing clamp plate 8 is also arranged on the main frame body 1 behind the closing clamp wheel 7 for closing the chain clamp 2 that is not closed after passing through the closing clamp wheel 7. Specifically, as Figure 2 and Figure 4 shown, as a conventional operation familiar to those skilled in the art, the installation angles of the closing clamp wheel 7 and the forced closing clamp plate 8 should correspond to the inclined force-bearing handle 11, and the installation angles can be customized according to the actual design angles of the force-bearing handle 11. This application will not elaborate further.

[0023] Furthermore, in order to better adapt to different models of chain clamps 2 and enable the closing clamp wheel 7 and the forced closing clamp plate 8 to be flexibly installed and adjusted, the horizontal distance between the closing clamp wheel 7 and the forced closing clamp plate 8 and the chain clamp 2 is designed to be adjustable; specifically, as Figure 2 shown, a cylinder 3 is fixedly arranged at the upper end of the main frame body 1. The output end of the cylinder 3 is connected with a mounting plate 4. A front connecting plate 5 and a rear connecting plate 6 are arranged on the mounting plate 4. The closing clamp wheel 7 is rotatably arranged on the front connecting plate 5, and the forced closing clamp plate 8 is fixedly arranged on the rear connecting plate 6. By adjusting the cylinder 3, the positions of the closing clamp wheel 7 and the forced closing clamp plate 8 in the horizontal direction can be adjusted, and the distance between the two and the chain clamp 2 can be flexibly adjusted.

[0024] As Figure 2 , Figure 4 shown, in actual application, when the chain clamp 2 enters the return process, it is in the state as Figure 5The force-receiving handle 11 of the chain jaw 2 in the shown open state first contacts the closing jaw wheel 7. As the chain jaw 2 moves on the guide rail 12, under the extrusion of the closing jaw wheel 7, the force-receiving handle 11 and the movable clamping plate 10 rotate, causing the chain jaw 2 to be in the Figure 6 shown closed state; if an individual chain jaw 2 fails to close after passing through the force-receiving handle 11, when it passes through the forced closing jaw plate 8, the outwardly inclined force-receiving handle 11 contacts the forced closing jaw plate 8, and under the action of the forced closing jaw plate 8, the closing of the chain jaw 2 is achieved.

[0025] It should be noted that to ensure that the forced closing jaw plate 8 can close the chain jaw 2 that has not been closed by the closing jaw wheel 7, as a routine operation familiar to those skilled in the art, the length of the forced closing jaw plate 8 should be increased, and the distance between it and the force-receiving handle 11 should be designed to be smaller than the distance between the closing jaw wheel 7 and the force-receiving handle 11 to ensure that the forced closing jaw plate 8 can play the role of secondary closing insurance. This is a routine operation and will not be elaborated in this application.

[0026] It should be noted that the above embodiments only specifically and clearly describe the technical solutions and technical features of this application. For those skilled in the art, the solutions or features that belong to the prior art or common general knowledge are not described in detail in the above embodiments.

[0027] In addition, the technical solution of this application is not limited to the above embodiments only. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
