Description

TECHNICAL FIELD

[0001] The utility model relates to a material pressing rod technical field especially relates to an arc material pressing rod device, transfer pasting equipment. BACKGROUND

[0002] The material pressing rod is a tool for pressing or fixing materials in the industrial production process, which is usually applied in various mechanical processing occasions to ensure that the materials remain stable during processing and prevent the processing accuracy from being affected by material movement.

[0003] The traditional material pressing rod device is usually designed as a single-arm straight rod structure, and the circular cutter can only apply pressure to a single point position during operation due to the structural limitation of the straight rod. When processing products that require transfer pasting process, such as nanocrystalline, PC (polycarbonate), graphite, and thick PET (polyethylene terephthalate), etc. special materials, these materials often appear to be warped during the transfer pasting process. This warping can cause wrinkles, bulges, and other quality problems in the transferred materials. Figures 1-2 When an auxiliary rod is arranged on the steel roller to apply pressure to the head of the material, the tail of the material will appear to be warped. If an auxiliary rod is arranged on the steel roller to press the tail of the material, the head of the material will be warped instead. To solve this problem, two straight rods can be added to apply pressure to the head and tail of the material respectively. However, installing multiple straight rods makes the installation process cumbersome, which not only wastes valuable personnel installation time, but also reduces the installation efficiency. In addition, the added straight rods will occupy the space originally used for material movement, which not only limits the smoothness of material movement, but also may prevent other auxiliary workpieces from being installed.

[0004] Therefore, as shown in Figure 3 , a is the raw material, b is the transfer film, and c is the waste transfer film. By increasing the grammage of the transfer film, the warping phenomenon can be reduced to some extent, but it will also bring new problems. During the transfer pasting process, due to the increase in the weight of the transfer film, a pulling force may be generated along the material movement direction, which may cause the product itself to be lifted, resulting in a lack of patches and affecting the overall quality of the product.

[0005] Therefore, there is an urgent need for a material pressing rod device to solve the problem of material warping during the transfer pasting process. UTILITY MODEL CONTENTS

[0040] In view of the deficiencies in the prior art, the present inventors have long-term research and a large number of practices, and thus propose the technical scheme of the utility model. The technical scheme, the implementation process and principles will be further explained and described as follows.

[0041] The total thickness of the multi-layer graphite material is 0.15 mm. In the actual transfer operation process, due to the physical properties of the material, they are prone to warping, which may cause inaccuracy and low efficiency in the transfer process.

[0042] Please refer to Figure 4The embodiment provides a transfer equipment for transferring multi-layer graphite. The transfer equipment specifically comprises a plurality of rubber rollers N, a pressing roller shaft A1, a pressing roller shaft A2, a pressing roller shaft A3, a plurality of groove rollers AO, a cutter D, a driving shaft Q and an arc-shaped pressing rod device. The pressing roller shaft A3 has a first edge and a second edge. The first edge is tightly attached to a first roller shaft 11 in the arc-shaped pressing rod device, so that the stability and accuracy during the transfer process are ensured. Similarly, the second edge is tightly attached to a second roller shaft 12 in the arc-shaped pressing rod device. In actual operation, the raw material a and the transfer film b are respectively wound and conveyed along the arrow direction, and after accurate cutting and processing of the cutter D, the required product is finally obtained. After the transfer is completed, the product continues to convey along the production line, so that the multi-layer graphite with high quality is output.

[0043] Please refer to Figure 5 Unlike the traditional single-arm straight shaft, the arc-shaped pressing rod device in the embodiment is a single-arm arc-shaped double-shaft structure, which comprises an assembly frame, two roller shaft assemblies, two spacing adjustment assemblies and two height adjustment assemblies.

[0044] Firstly, the structure of the assembly frame is introduced. The assembly frame is composed of two arc-shaped supports 1, two spacing adjustment supports 2 and two height adjustment supports 3. The two arc-shaped supports 1 are spaced apart and oppositely arranged along a first direction, and extend along a second direction perpendicular to the first direction as a whole. The two arc-shaped supports 1 are provided with assembly slot holes. The two spacing adjustment supports 2 are also spaced apart and oppositely arranged along the first direction, and extend along the first direction as a whole, and the spacing adjustment supports 2 are provided with first adjustment slot holes for adjusting the spacing. The two height adjustment supports 3 are spaced apart and oppositely arranged along the second direction, and extend along the second direction as a whole, and the height adjustment supports 3 are provided with second adjustment slot holes for adjusting the height.

[0045] Then, the roller shaft assembly is introduced. The roller shaft assembly comprises a first roller shaft 11, a second roller shaft 12 and two groups of first bolt pairs. The two roller shafts are spaced apart and assembled on the arc-shaped support 1 along the second direction, and the two ends are fixed in the assembly slot hole through the first bolt pair.

[0046] The spacing adjustment assembly comprises a first spacing adjustment roller, a second spacing adjustment roller and two groups of second bolt pairs. One end of the two spacing adjustment rollers is arranged on the first adjustment slot hole through the second bolt pair, and the other end is arranged on the second adjustment slot hole. The height adjustment assembly comprises a first height adjustment roller, a second height adjustment roller and two groups of third bolt pairs. One end of the two height adjustment rollers is arranged on the second adjustment slot hole through the third bolt pair, and the other end is arranged on the external equipment frame.

[0047] Finally, the first, second and third bolt pairs all comprise a bolt and a nut.

[0048] In this aspect, the first roller shaft 11 and the second roller shaft 12, together with the two arc-shaped brackets 1, can be configured to switch between a locked state and an unlocked state. In the locked state, a stable fixed fit is formed between the first roller shaft 11, the second roller shaft 12, and the arc-shaped brackets 1. Through the two sets of first bolt pairs, the spacing of the first roller shaft 11 and the second roller shaft 12 in the second direction is fixed and cannot be changed. This locking mechanism ensures that the spacing of the rollers remains unchanged during specific operations, thereby ensuring processing accuracy and stability. On the other hand, when the first roller shaft 11, the second roller shaft 12, and the two arc-shaped brackets 1 are in the unlocked state, they exhibit a loose fit. In this state, the first roller shaft 11 and the second roller shaft 12 can freely move along the length of the assembly slot, making the spacing of the rollers in the second direction adjustable. This design allows users to flexibly adjust the roller spacing according to different processing needs to accommodate workpieces of different sizes and shapes. The two arc-shaped brackets 1 can better adapt to the size of the material pressing roller A, thereby providing more uniform and effective pressing force. The first roller shaft 11 and the second roller shaft 12 ensure that the material can be stably pressed and maintain the appropriate spacing during operation, thereby improving processing efficiency and quality. Preferably, the two arc-shaped brackets 1 can be designed with precise curvature and material selection to improve the ability to withstand specific loads and maintain long-term durability.

[0049] In this aspect, the first spacing adjustment roller, the second spacing adjustment roller, and the spacing adjustment bracket 2 can be configured to be in a locked state and an unlocked state. Specifically, when the first spacing adjustment roller, the second spacing adjustment roller, and the spacing adjustment bracket 2 are set to the locked state, a fixed fit is formed between them. In this state, the spacing of the first spacing adjustment roller and the first roller shaft 11 in the first direction is locked, ensuring the fixed position; similarly, the spacing of the second spacing adjustment roller and the second roller shaft 12 in the first direction is also locked. Conversely, when the first spacing adjustment roller, the second spacing adjustment roller, and the spacing adjustment bracket 2 are set to the unlocked state, the fit between the first spacing adjustment roller, the second spacing adjustment roller, and the spacing adjustment bracket 2 becomes loose. In this state, the first spacing adjustment roller and the second spacing adjustment roller can freely move along the length of the first adjustment slot, making the spacing of the first spacing adjustment roller and the first roller shaft 11 in the first direction adjustable; similarly, the spacing of the second spacing adjustment roller and the second roller shaft 12 in the first direction also becomes adjustable, providing greater flexibility and adjustment range.

[0050] In the scheme, the first height adjusting roller, the second height adjusting roller and the height adjusting support 3 can be configured in a locked state and an unlocked state. Specifically, when the first height adjusting roller and the second height adjusting roller are respectively arranged in the locked state with the two height adjusting supports 3, a fixed fit relationship is formed. In this state, the distance between the first height adjusting roller and the first distance adjusting roller in the second direction is locked and remains unchanged; similarly, the distance between the second height adjusting roller and the second distance adjusting roller in the second direction is also fixed. Conversely, when the first height adjusting roller and the second height adjusting roller are respectively arranged in the unlocked state with the two height adjusting supports 3, a loose fit is formed. In this state, the first height adjusting roller and the second height adjusting roller are respectively freely movable along the length direction of the second adjusting slot hole of the two height adjusting supports 3, so that the distance between the first height adjusting roller and the first distance adjusting roller in the second direction becomes adjustable and can be adjusted according to actual needs; similarly, the distance between the second height adjusting roller and the second distance adjusting roller in the second direction also has adjustability.

[0051] In general, since the assembly frame is designed as an integral structure, it is ensured that the height of the first roller shaft 11 and the second roller shaft 12 will change synchronously during the distance adjustment and the height adjustment, so that the first roller shaft 11 and the second roller shaft 12 can tightly press the material pressing roller shaft A, thereby ensuring the accuracy and stability of the entire assembly process.

[0052] In order to further ensure the stability and reliability of the height adjustment, the second fixing mechanism is provided with a screw lock head, and the second end can be firmly fixed on the external equipment frame through the screw lock head, thereby ensuring the stability and safety of the entire support assembly.

[0053] In summary, the traditional single-arm straight shaft is changed into a single-arm arc-shaped double-shaft structure, and through the cooperative work of the first roller shaft 11 and the second roller shaft 12, pressure can be respectively applied to the head and tail of the material, effectively reducing the possible lifting phenomenon of the material during the processing process, and the product yield is improved by 4%.

[0054] It should be understood that the above embodiments are only for illustrating the technical concept and characteristics of the present application, and the purpose is to enable those skilled in the art to understand the content of the present application and implement it, and cannot limit the protection scope of the present application. Any equivalent changes or modifications made according to the spirit and essence of the present application should be covered within the protection scope of the present application.
