Existing technologies typically use tension adjustment devices to control material conveying, but these devices have numerous drawbacks. These devices control conveying by applying tension to the material. However, this tension can cause excessive stretching or squeezing of the material, increasing the risk of damage. Furthermore, unstable or uneven tension can cause variations in material thickness, impacting product consistency and quality stability. Utility Model Content

[0007] Feed squeeze rollers, the feed squeeze rollers are rotatably arranged on the frame, there are multiple feed squeeze rollers, an extrusion gap is formed between two feed squeeze rollers in a group, and there are at least two groups of feed squeeze rollers.

[0008] The pressing roller is rotatably arranged on the frame, and the pressing rollers form a group of two, and a pressing gap is formed between the two pressing rollers in a group. The pressing rollers are arranged below the feed extrusion roller.

[0009] The buffer is swingably arranged on the frame and is located between the feed extrusion roller and the pressing roller. After the material passes through the extrusion gap and is squeezed by the feed extrusion roller, it passes through the buffer and enters the pressing gap and is pressed by the pressing roller.

[0010] As a further technical solution, it also includes:

[0011] There are several protection wheels, which are rotatably arranged at both ends of the buffer.

[0012] As a further technical solution, the buffer has a material-receiving part, a transition part and a rotating shaft. The rotating shaft is rotatably arranged on the frame. The material-receiving part and the transition part are respectively arranged on both sides of the rotating shaft. The material-receiving part is arc-shaped and faces the extrusion gap. The transition part has a bending direction opposite to that of the material-receiving part.

[0013] As a further technical solution, the material receiving portion and the transition portion both have a protection portion, the protection portion is arc-shaped, the protection portion is bent toward the rotation axis, and the protection wheels are arranged at the end of the protection portion.

[0014] As a further technical solution, the frame has a plurality of slide slots, which are respectively arranged on both sides of the buffer member, and further includes:

[0015] A sliding member is slidably arranged in the sliding groove, and the sliding member is configured to push the sliding member to slide in the sliding groove after the buffer member swings.

[0016] As a further technical solution, it also includes:

[0017] A first elastic member, wherein one end of the first elastic member acts on the buffer member and the other end acts on the frame to provide a force for the buffer member to be located between the two sliding members.

[0018] As a further technical solution, the first elastic member is a torsion spring.

[0019] As a further technical solution, the transition portion has a mounting groove and further includes:

[0020] A rotating roller, the rotating roller is rotatably arranged in the mounting groove,

[0021] A speed sensor is arranged in the installation groove and is used to detect the rotation speed of the rotating roller.

[0022] The working principle and beneficial effects of the utility model are as follows:

[0023] In this utility model, the buffer mechanism primarily consists of a frame, feed squeeze rollers, a closing roller, and a buffer. The feed squeeze rollers are rotatably mounted on the frame and are arranged in groups of two or more, with a squeeze gap formed between the two feed squeeze rollers in each group. The closing rollers are also rotatably mounted on the frame, with two closing rollers in each group forming a squeeze gap, located below the feed squeeze rollers. The buffer is swingably mounted on the frame and positioned between the feed squeeze rollers and the closing rollers. Multiple feed squeeze rollers are arranged in groups and rotate to perform preliminary squeezing of the material. The existence of the squeeze gap controls the thickness and pressure of the material, ensuring that the material is in the appropriate state before entering the next stage. The closing rollers perform final closing of the initially squeezed material, achieving the desired thickness and density. The closing gap between the two closing rollers precisely controls the size of the material after closing. Positioned below the feed squeeze rollers, the buffer ensures smooth material transfer from the feed squeeze rollers to the closing rollers, ensuring a continuous production process. The buffer swings between the feed squeeze rollers and the closing rollers, providing both a buffer and a transitional function. After exiting the feed squeeze rollers, the material passes through the buffer before entering the closing rollers. This prevents direct impact with the closing rollers, minimizing damage. The buffer's oscillating characteristics adapt to varying material flow and pressure, ensuring material stability as it enters the closing gap. The initial compression of the feed squeeze rollers and the final compression of the closing rollers achieve higher density and uniformity in the solid-state, cell-free energy storage power supply material, improving product quality and performance. The buffer reduces shock and vibration during the production process, further ensuring product quality stability. The design of multiple feed squeeze rollers and two sets of closing rollers enables continuous production and improves efficiency. The smooth transition of material between different stages reduces production interruptions and adjustment time. The buffer's oscillating characteristics quickly adapt to changes in the production process, enhancing production flexibility and adaptability. The buffer reduces direct impact of the material on the closing rollers, reducing the risk of damage to the closing rollers. This extends the life of the equipment and reduces maintenance and replacement costs.

[0024] Compared to existing tension adjustment devices, buffers offer better material protection. Tension adjustment devices typically control the conveying process by applying a certain tension to the material. However, this tension can cause excessive stretching or squeezing of the material during conveyance, increasing the risk of material damage. The buffer, by its oscillating nature, acts as a buffer during material conveyance, reducing impact and friction. As the material exits the feed rollers, the buffer absorbs some of the energy, preventing it from directly impacting the closing rollers or other equipment components, thereby reducing the possibility of material damage. In the manufacturing process of solid-state, cellless energy storage power supplies, some materials may be fragile or sensitive and easily damaged by external forces. The use of buffers effectively protects these materials and ensures product quality. When adjusting material conveyance, unstable or uneven tension may cause material thickness variations. This thickness variation can affect product consistency and quality stability. The buffer's oscillating design better adapts to fluctuations in material flow and pressure, maintaining material stability during conveyance. When the material flow or pressure changes, the buffer automatically adjusts its position and angle to maintain a relatively stable material thickness. Furthermore, the presence of buffers can reduce vibration and swaying during material conveying, further minimizing the possibility of thickness variations. Reducing the risk of material damage and thickness variations helps improve the product quality of solid-state, coreless energy storage power supplies. This improves product consistency and stability, enabling them to meet higher quality standards and meet customer demands. Reducing material damage reduces scrap rates, reduces interruptions and adjustment time during production, and thus improves production efficiency. Furthermore, stable material thickness helps increase automation and production speed. Reducing material damage reduces raw material waste and costs. Furthermore, stable product quality reduces subsequent quality inspection and handling costs. Furthermore, buffers are relatively simple to use and require less maintenance, making them more cost-effective than complex tension adjustment devices. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Reference Figure 1~Figure 2, is an embodiment of the utility model, which proposes a buffer mechanism for rolling of a solid-state coreless energy storage power supply, including a frame 1, a feed extrusion roller 2 rotatably arranged on the frame 1, a plurality of feed extrusion rollers 2, a group of two feed extrusion rollers 2 forming an extrusion gap 201, at least two groups of feed extrusion rollers 2, a combining roller 3 rotatably arranged on the frame 1, two combining rollers 3 form a group, a combining gap 301 is formed between the two combining rollers 3 in a group, the combining roller 3 is arranged below the feed extrusion roller 2, a buffer 4 is swingably arranged on the frame 1, and is located between the feed extrusion roller 2 and the combining roller 3, after the material passes through the extrusion gap 201 and is squeezed by the feed extrusion roller 2, it passes through the buffer 4 and enters the combining gap 301 and is pressed by the combining roller 3.

[0034] In this embodiment, the buffer mechanism is mainly composed of a frame 1, a feed extrusion roller 2, a pressing roller 3 and a buffer 4. The feed extrusion roller 2 is rotatably set on the frame 1, and the number is several and at least two groups. An extrusion gap 201 is formed between the two feed extrusion rollers 2 in each group. The pressing roller 3 is also rotatably set on the frame 1, two in a group, and a pressing gap 301 is formed between the two pressing rollers 3 in a group, which is located below the feed extrusion roller 2. The buffer 4 is swingably set on the frame 1, and is located between the feed extrusion roller 2 and the pressing roller 3. Multiple feed extrusion rollers 2 are arranged in groups and perform preliminary extrusion on the material by rotation. The existence of the extrusion gap 201 can control the thickness and pressure of the material, ensuring that the material is in a suitable state when entering the next link. The pressing roller 3 performs final pressing on the material that has been preliminarily extruded to achieve the required thickness and density. The pressing gap 301 between the two pressing rollers 3 can accurately control the size of the material after pressing. The design located below the feed squeeze roller 2 allows the material to smoothly transition from the feed squeeze roller 2 to the closing roller 3, ensuring the continuity of the production process. The buffer 4 is swingably arranged between the feed squeeze roller 2 and the closing roller 3, acting as a buffer and transition. The buffer 4 can determine the amount of material on the buffer through a pressure sensor or servo encoder, and control the feeding speed by controlling the speed of the feed squeeze roller 2, so that all rollers have the same speed and reach a balanced state. When the material exits the feed squeeze roller 2 and enters the closing roller 3 through the buffer 4, it can prevent the material from directly impacting the closing roller 3, reducing damage to the closing roller 3. The swing characteristics of the buffer 4 can adapt to different material flow rates and pressure changes, ensuring the stability of the material when entering the closing gap 301. Through the initial squeezing of the feed squeeze roller 2 and the final closing of the closing roller 3, the material of the solid-state non-cell energy storage power supply can achieve a higher density and uniformity, improving the quality and performance of the product. The presence of the buffer 4 can reduce impact and vibration during the production process, further ensuring the quality stability of the product. The design of multiple sets of feed squeeze rollers 2 and two sets of closing rollers 3 enables continuous production and improves production efficiency. The smooth transition of materials between different links reduces production interruptions and adjustment time. The swinging characteristics of the buffer 4 quickly adapt to changes in the production process, improving production flexibility and adaptability. The buffer 4 reduces direct impact of the material on the closing roller 3, reducing the risk of damage to the closing roller 3. This extends the service life of the equipment and reduces equipment maintenance and replacement costs.

[0035] Compared to conventional tension adjustment devices, the buffer 4 provides better material protection. Tension adjustment devices typically control the conveying process by applying a certain tension to the material. However, this tension may cause the material to be overstretched or squeezed during conveyance, increasing the risk of material damage. The buffer 4, through its oscillating nature, acts as a buffer during material transport, reducing the impact and friction forces on the material. When the material exits the feed squeeze roller 2, the buffer 4 absorbs some of the energy, preventing the material from directly impacting the closing roller 3 or other equipment components, thereby reducing the possibility of material damage. During the manufacturing process of solid-state, cellless energy storage power supplies, some materials may be fragile or sensitive and easily damaged by external forces. The use of the buffer 4 effectively protects these materials and ensures product quality. When adjusting material conveyance, the tension adjustment device may cause material thickness to vary due to unstable or uneven tension. This thickness variation can affect product consistency and quality stability. The oscillating configuration of the buffer 4 better adapts to fluctuations in material flow and pressure, maintaining material stability during conveyance. When the flow or pressure of the material changes, the buffer 4 can automatically adjust its position and angle to keep the thickness of the material relatively stable. In addition, the presence of the buffer 4 can also reduce the vibration and shaking of the material during transportation, further reducing the possibility of thickness changes. Reducing the risk of material damage and thickness changes helps to improve the product quality of solid-state coreless energy storage power supplies. The consistency and stability of the product are improved, and can meet higher quality standards and customer needs. Reducing material damage can reduce the scrap rate, reduce interruptions and adjustment time in the production process, and thus improve production efficiency. At the same time, stable material thickness also helps to improve the degree of automation and production speed of the production process. Reducing material damage can reduce the waste and cost of raw materials. At the same time, stable product quality can also reduce subsequent quality inspection and processing costs. In addition, the use of the buffer 4 is relatively simple, the maintenance cost is low, and compared with complex tension adjustment devices, it has a higher cost performance.

[0036] Furthermore, it also includes protection wheels 5, which are multiple and rotatably arranged at both ends of the buffer member 4.

[0037] In this embodiment, several protection wheels 5 are rotatably arranged at both ends of the buffer 4. Such a layout can guide and protect the material from both sides when the material passes through the buffer 4. The provision of multiple protection wheels 5 can increase the contact points with the material and improve the guiding and protection effects. The protection wheels 5 can rotate, which reduces the friction when the material contacts the protection wheels 5, and the material is transported more smoothly. The rotating protection wheels 5 can adapt to different material conveying speeds and reduce the pulling or blockage of the material caused by speed changes. When the material passes through the buffer 4, it may cause friction or collision with the edge of the buffer 4. The presence of the protection wheels 5 can share some of the force of this friction and collision, thereby reducing wear and damage to the buffer 4. The service life of the buffer 4 is extended and the maintenance cost of the equipment is reduced.

[0038] Furthermore, the buffer member 4 has a supporting portion 401, a transition portion 402 and a rotating shaft 403. The rotating shaft 403 is rotatably set on the frame 1. The supporting portion 401 and the transition portion 402 are respectively set on both sides of the rotating shaft 403. The supporting portion 401 is arc-shaped and faces the extrusion gap 201. The transition portion 402 has an opposite bending direction to the supporting portion 401.

[0039] In this embodiment, the buffer member 4 includes a receiving portion 401, a transition portion 402, and a rotating shaft 403. The rotating shaft 403 is rotatably mounted on the frame 1, and the receiving portion 401 and the transition portion 402 are respectively arranged on both sides of the rotating shaft 403. The receiving portion 401 is arc-shaped and faces the extrusion gap 201, and the transition portion 402 is curved in the opposite direction to the receiving portion 401. The arc-shaped receiving portion 401 can better receive the material coming out of the feed extrusion roller 2. Because it faces the extrusion gap 201, the material can fall smoothly onto the receiving portion 401, reducing the scattering of the material. The arc-shaped design increases the contact area with the material, making the material more stable on the receiving portion 401 and less likely to slip. At the same time, the arc-shaped shape also helps guide the material to flow toward the transition portion 402. The transition portion 402 is curved in the opposite direction to the receiving portion 401, and serves to smoothly transition the material from the receiving portion 401 to the closing pressure gap 301. As the material moves from the receiving section 401 to the transition section 402, its speed and direction gradually adjust due to the change in curvature, allowing it to smoothly enter the pressing rollers 3 for pressing. The design of the transition section 402 reduces the impact and vibration of the material as it enters the pressing gap 301, ensuring the stability and uniformity of the pressing process. The rotating shaft 403 is rotatably mounted on the frame 1, allowing the buffer 4 to automatically adjust its angle and position according to the material flow and pressure. When the material flow is high or the pressure is high, the buffer 4 can adapt to these changes by rotating the rotating shaft 403, maintaining stable material transportation. The presence of the rotating shaft 403 increases the flexibility and adaptability of the buffer 4, enabling it to better meet the needs of different production conditions. Stable material transportation and transition can reduce interruptions and adjustment time during the production process, thereby improving production efficiency. The design of the receiving section 401 and transition section 402 ensures smooth material transfer between different links, preventing material blockage or accumulation. For large-scale production of solid-state, cell-free energy storage power supplies, this efficient buffering mechanism can significantly improve production capacity.

[0040] Furthermore, both the material receiving portion 401 and the transition portion 402 have a protection portion 404 . The protection portion 404 is arc-shaped and bends toward the rotation axis 403 . The protection wheels 5 are arranged at the ends of the protection portion 404 .

[0041] In this embodiment, both the material receiving portion 401 and the transition portion 402 have a protective portion 404. The protective portion 404 is arc-shaped and bends in the direction of the rotating shaft 403. The protective wheel 5 is arranged at the end of the protective portion 404. The arc-shaped design of the protective portion 404 further provides protection for the material. When the material moves in the material receiving portion 401 or the transition portion 402, the protective portion 404 can prevent the material from sliding from the side or being disturbed by the outside. Its design, which is opposite to the bending direction of the material receiving portion 401 or the transition portion 402, ensures that the material will not be worn when it is on the edge of the buffer 4. The protective portion 404 can reduce the direct contact between the material and the edge of the buffer 4, thereby reducing wear. In particular, in the case of friction and collision that may occur during the material transmission process, the protective portion 404 can effectively disperse these forces and protect the main structure of the buffer 4. The protective wheel 5 is arranged at the end of the protective portion 404, which can more accurately guide the flow direction of the material. Due to the rotational characteristics of the protection wheels 5 , they can provide additional power and guidance when the material passes through, ensuring that the material smoothly enters the pressing gap 301 from the buffer member 4 .

[0042] Furthermore, the frame 1 has a slide groove 101, which is a plurality of slide grooves 101 and is respectively arranged on both sides of the buffer 4. It also includes a sliding member 6, which is slidably arranged in the slide groove 101. The sliding member 6 is configured to push the sliding member 6 to slide in the slide groove 101 after the buffer 4 swings.

[0043] In this embodiment, the frame 1 has several chutes 101, one on each side of the buffer 4. It also includes a slider 6, which slides within the chutes 101 and, after the buffer 4 swings, pushes the slider 6 to slide within the chutes 101. The chutes 101 provide a clear motion path for the slider 6, ensuring that it slides in a specific direction. This helps maintain the stability and controllability of the buffer 4's swing. The chutes 101 limit the slider 6's range of motion, preventing it from excessive movement or deviation from its intended position. This is crucial for ensuring the proper operation and safety of the buffer mechanism. When the buffer 4 swings, a certain amount of force is generated. The slider 6 transfers the force generated by the buffer 4's swing to the chutes 101, thereby achieving force transfer between the buffer 4 and the frame 1. The sliding of the slider 6 within the chutes 101 can adjust the buffer 4's swing amplitude and frequency, and thus the buffering effect. By changing the position of the slider 6 within the chutes 101, the performance of the buffer mechanism can be optimized according to different production requirements and material properties. The combination of chute 101 and slider 6 makes the oscillation of buffer 4 more stable and predictable. This helps ensure material stability during transport and reduces material damage or production interruptions caused by unstable buffering. By adjusting the position of slider 6 within chute 101, the buffering performance of the buffer mechanism can be easily adjusted to suit different material characteristics and production requirements. The positioning of slider 6 also facilitates operator adjustments to the entire equipment, avoiding material pile-up or breakage, and improving the equipment's continuous production capacity.

[0044] Furthermore, a first elastic member 7 is included. One end of the first elastic member 7 acts on the buffer member 4 and the other end acts on the frame 1 to provide a force for the buffer member 4 to be located between the two sliding members 6.

[0045] In this embodiment, the first elastic member 7 ensures that the buffer 4 always remains in a specific position between the two sliding members 6. In the absence of external forces, the elastic force of the elastic member maintains the buffer 4 in a balanced state, preventing it from swinging excessively or deviating from its normal position. This stable position helps ensure stable material transport through the buffer 4, reducing material transport disruptions or damage caused by unstable buffer 4 positions. As material passes through the buffer 4, it exerts an impact force on the buffer 4. The first elastic member 7 absorbs some of this impact, providing further cushioning. The deformation of the elastic member mitigates the impact of the material on the buffer 4, protecting the buffer 4 and the entire rolling mechanism from excessive pressure. Combined with the inherent swinging characteristics of the buffer 4, the first elastic member 7 provides a more effective cushioning effect, reducing the risk of material damage during the rolling process. If the material flow rate, pressure, or other parameters change, the first elastic member 7 can automatically adjust the position and force applied to the buffer 4 based on the actual conditions. For example, as the material flow rate increases, the buffer 4 may be subjected to greater pressure, and the elastic member will compress accordingly to accommodate this change. This automatic adjustment capability allows the buffer mechanism to better adapt to varying production conditions, improving production stability and reliability. The stable position of the buffer 4 and its enhanced cushioning action reduce vibration and impact during material transfer, thereby improving product quality and consistency. This is particularly important for products such as solid-state, cellless energy storage power supplies, which require high quality.

[0046] Furthermore, the first elastic member 7 is a torsion spring.

[0047] In this embodiment, the torsion spring can provide a large elastic force within a relatively small space. In the buffer mechanism, one end of the torsion spring acts on the buffer 4 and the other end acts on the frame 1, providing a stabilizing force between the two sliding members 6 of the buffer 4. This elastic force can be adjusted according to actual needs to accommodate different materials and production conditions. When the material impacts the buffer 4, the torsion spring absorbs the impact energy, acting as a buffer and protecting the equipment and materials. Since the buffer 4 oscillates during operation, the torsion spring's torsional properties make it well suited to this oscillating motion. The torsion spring continuously stores and releases energy during the buffer 4's oscillation, maintaining the buffer 4's smooth movement. Furthermore, the spring force of the torsion spring provides corresponding support at different oscillation angles, ensuring that the buffer 4 remains in the proper position. Torsion springs are typically made of high-strength metal materials and have high reliability and durability. Over long-term use, the torsion spring maintains stable elastic properties and is less susceptible to fatigue failure or damage. This is crucial for the buffer mechanism used in solid-state, coreless energy storage power supply roll pressing, as the equipment must operate stably in a continuous production environment.

[0048] Furthermore, the transition portion 402 has a mounting groove 405 and further includes a rotating roller 8 . The rotating roller 8 is rotatably disposed in the mounting groove 405 . A speed sensor is disposed in the mounting groove 405 for detecting the rotation speed of the rotating roller 8 .

[0049] In this embodiment, the rotation of the rotating roller 8 can guide the material to a certain extent, helping to adjust the position of the material in the transition section 402, ensuring that the material can accurately enter the pressing roller 3 for pressing, and improving the accuracy and stability of production. By detecting the rotation speed of the rotating roller 8, the speed sensor can indirectly reflect the transmission speed of the material in the transition section 402. This is very important for controlling the entire rolling process. By monitoring the material transmission speed in real time, the rotation speed of the feed squeeze roller 2 and the pressing roller 3 can be adjusted in time to ensure that the material transmission speed at each link is matched, avoiding problems such as material accumulation or breakage. The speed sensor can also be used for fault diagnosis. If the rotation speed of the rotating roller 8 is abnormal, it may mean that there is a problem with the material transmission, such as material blockage or damage to the rotating roller 8. Through monitoring by the speed sensor, these problems can be discovered in a timely manner and appropriate measures can be taken to address them, avoiding greater impact on production.
