Technical Field
[0001] The utility model relates to the technical field of film stretching equipment, in particular to an auxiliary film threading device for film stretching equipment. Background Technique
[0002] With the development of lithium battery technology, the diaphragm processing technology has become more and more perfect. When processing the diaphragm, it is necessary to stretch the diaphragm on the film stretching production line. The existing film stretching production line is mainly composed of a plurality of stretching rollers arranged vertically and horizontally. At the beginning of production or when the film is interrupted in the middle, the film needs to pass through a plurality of rollers in sequence from the entrance of the stretching equipment until it is threaded to the outlet of the equipment. The traditional film threading method requires manual threading of the film from the film inlet along the film path trajectory to the film outlet. Due to the long distance from the film inlet to the film outlet and the small gap between the rollers, motors and heat-conducting oil pipes are also arranged on both sides of the equipment, resulting in time-consuming and laborious manual film threading in the early stage and potential safety hazards, leading to low work efficiency.
[0003] Therefore, we have developed and designed an auxiliary film threading device. By fixing guide wheels at the ends of the rollers and laying a chain that can travel along the film path trajectory on the guide wheels, when threading the film, only need to fix the film on the chain at the film inlet and drive the chain to rotate, then the film can be automatically threaded along the film path trajectory, greatly improving the film threading efficiency.

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 1-5 , this embodiment provides an auxiliary film threading device for a film stretching device, including a support wall panel 1, a chain 4, and a plurality of guide sprockets 6. A plurality of chain guide wheels corresponding to the stretching rollers 14 are rotatably provided on the support wall panel 1. The chain 4 sequentially bypasses a plurality of chain guide wheels according to the film path. To ensure the stability of the movement of the chain 4, as Figure 4 shown, guide grooves 15 are formed in the chain guide wheels, and the chain 4 is movably arranged in the guide grooves 15; specifically, as Figure 1 and Figure 5 shown, the chain guide wheel 1 is divided into an upper chain guide wheel 2 and a lower chain guide wheel 3, and the upper chain guide wheel 2 and the lower chain guide wheel 3 are arranged at intervals, so as to correspond to the stretching roller 14; it should be noted that the number and distribution of the guide sprockets 6 should be conventional settings familiar to those skilled in the art and can be arranged according to requirements, which play a role in supporting and driving the movement of the chain 4. They are mainly distributed on the periphery of the support wall panel 1. By driving one of the guide sprockets 6 to rotate by a motor, the chain 4 can be driven to move, which is a conventional operation and will not be elaborated in this application.
[0021] To ensure the stability of the movement of the chain 4 and make the chain 4 always in a suitable tension state according to requirements, the auxiliary film threading device further includes a counterweight tensioning device 5 to adjust the tension of the chain 4; specifically, as Figures 1-3 shown, the counterweight tensioning device 5 includes a fixing plate 7. A plurality of evenly distributed counterweight main guide wheels 8 are rotatably provided on the fixing plate 7. A vertical guide rail 13 is provided on the fixing plate 7. A counterweight frame 9 located below the counterweight main guide wheels 8 is slidably arranged on the guide rail 13. A plurality of counterweight sub-guide wheels 10 corresponding to the counterweight main guide wheels 8 are arranged inside the counterweight frame 9. The counterweight main guide wheels 8 and the counterweight sub-guide wheels 10 are arranged at intervals. Preferably, as a conventional setting, in this application, three counterweight main guide wheels 8 are provided and two counterweight sub-guide wheels 10 are provided. The chain 4 sequentially bypasses the counterweight main guide wheels 8 and the counterweight sub-guide wheels 10. Counterweight rods 11 are arranged on both sides of the counterweight frame 9, and counterweight plates 12 are hung on the counterweight rods 11. By disassembling and assembling the counterweight plates 12, the tension of the chain 4 can be easily adjusted.
[0022] It should be noted that in order to achieve the stability of the chain 4 on the counterweight main guide wheel 8 and the counterweight auxiliary guide wheel 10, guide grooves communicating with the chain guide wheel should also be provided on the counterweight main guide wheel 8 and the counterweight auxiliary guide wheel 10.
[0023] In order to enable the chain guide wheel to rotate independently of the stretching roller 14, as Figure 4 shown, a plurality of support rings 16 corresponding to the chain guide wheel are fixedly arranged on the support wall plate 1 through fixing rods 17. A plurality of rotatable bearings 18 are evenly arranged on the front side of the support ring 16. The chain guide wheel is designed as a hollow structure with through holes. Limit grooves 19 are provided on the inner side of the chain guide wheel. The bearings 18 are clamped inside the limit grooves 19 and are in rolling connection with the limit grooves 19 to realize the installation of the chain guide wheel; it should be noted that as a conventional setting, the bearings 18 can also be replaced by rollers. This setting is a conventional structure replacement familiar to those skilled in the art and will not be elaborated in this application. This design enables the roller shaft of the stretching roller 14 to pass through the chain guide wheel and the support ring 16, thereby realizing the independent rotation of the chain guide wheel and the stretching roller 14. When threading the film, only the chain 4 needs to rotate, and there is no need for the stretching roller 14 to rotate; after threading the film, only the stretching roller 14 needs to rotate, and there is no need for the chain 4 to move synchronously, which can effectively reduce the mechanical failure rate; of course, as a conventional setting, according to actual needs, the chain guide wheel can also be sleeved on one side of the stretching roller 14 to realize the synchronous rotation of the two. This is a conventional operation familiar to those skilled in the art and will not be elaborated in this application.
[0024] In practical applications, as Figure 5 shown, when threading the film, on one side of the stretching roller 14 (i.e., the film inlet), the film is fixed to the chain 4 at the film inlet, and then the chain 4 is driven to move. The chain 4 drives the film to move along the stretching trajectory, and then the film can be driven to bypass each stretching roller 14 in turn to realize the film threading operation of the film on the stretching device. Subsequently, the film is separated from the chain 4, and only the stretching roller 14 needs to be driven to rotate.
[0025] 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.
[0026] In addition, the technical solutions of this application are not limited to the above embodiments. 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 implementation manners that can be understood by those skilled in the art.
