[0035] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by technical personnel in this field without creative work are within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the fact that a better connection structure can be formed by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the present invention can be combined interactively without conflicting with each other.

[0036] The utility model discloses a pinch roller mechanism, which is used for stable clamping, precise conveying and tension control of a waste strip, and aims to improve the automation level and operational safety of waste treatment in the lithium battery manufacturing process.

[0037] Reference Figure 1-3A pinching roller mechanism includes: a base 100 and a fixed seat 110 and a mounting seat 120 provided on the base 100; a main roller 111 is installed on the fixed seat 110, and the main roller 111 is transmission-connected to a driving member 200, and the driving member 200 can drive the main roller 111 to rotate relative to the fixed seat 110; a pressure roller 121 is installed on the mounting seat 120, and the pressure roller 121 is parallel to the main roller 111 and can rotate relative to the mounting seat 120; the mounting seat 120 is slidingly connected to the base 100 through a connecting member 130, and an elastic member 140 is provided between the mounting seat 120 and the base 100, and the elastic member 140 can be used to drive the pressure roller 121 to abut against the main roller 111, thereby clamping the waste material. The continuous pressing force provided by the elastic member 140 allows the main roller 111 to cooperate with the pressure roller 121 to clamp the waste material, ensuring the reliability and stability of the waste belt during transportation. This effectively prevents the waste belt from collapsing during transportation, while also providing appropriate tension control to prevent breakage or deformation caused by uneven tension. Furthermore, the main roller 111 acts as the active roller, with the driving member 200 providing the driving force, while the pressure roller 121 acts as the driven roller. The cooperation between the active and driven rollers in conveying the waste material ensures that the waste belt can stably travel along the designated path, reducing the need for manual intervention in waste belt handling.

[0038] In some embodiments, the main roller 111 and the pressure roller 121 have the same diameter. This ensures uniform pressure distribution across the entire roller surface when contacting the waste, preventing damage or uneven deformation of the waste caused by uneven pressure. This improves the synchronization and stability of the conveying process, reduces waste deviation and damage, and thus enhances conveying efficiency and waste handling quality. This also simplifies maintenance, reduces operating costs, helps extend equipment life, and enhances the reliability of the entire roller-pressing system and the continuity of the production process.

[0039] In some embodiments, reference Figure 1-3 The connecting member 130 comprises a linear bearing 131 and a guide shaft 132. The linear bearing 131 is fixedly connected to the base 100, and the guide shaft 132 passes through the linear bearing 131. One end of the guide shaft 132 is fixedly connected to the mounting seat 120, and the other end is provided with a stop. The coordination of the linear bearing 131 and the guide shaft 132 improves the stability and guidance accuracy of the mechanism. The use of the linear bearing 131 and the guide shaft 132 as the connecting member 130 ensures smooth and precise reciprocating motion of the mounting seat 120 on the base 100.

[0040] Further, refer to Figure 1-3The stopper is a stop plate 133. Multiple connectors 130 are provided, and the guide shafts 132 of these multiple connectors 130 are connected to the same stop plate 133. The provision of stop plate 133 and multiple connectors 130 enhances the stability and compactness of the mechanism. Stop plate 133 limits the range of motion of guide shaft 132, and multiple connectors 130 evenly distribute force, improving the stability of the overall structure.

[0041] Furthermore, the elastic member 140 is a spring, one end of which is connected to the base 100 and the other end is connected to the stop plate 133. The spring is in a stretched state to provide a continuous pressing force to force the pressure roller 121 toward the main roller 111. It is understood that the spring in a stretched state can provide a continuous and stable pressing force, ensuring that the pressure roller 121 and the main roller 111 tightly clamp the waste material.

[0042] Further, refer to Figure 3 The base 100 is provided with a plurality of first connecting rods 150, and the stop plate 133 is provided with a plurality of second connecting rods 160 corresponding to the first connecting rods 150; the number of the springs is the same as the first connecting rods 150 or the second connecting rods 160, and the ends of the springs are connected to the first and second connecting rods 160, respectively. In a specific embodiment, the ends of the first and second connecting rods 150 and 160 are provided with connecting holes, and the ends of the springs have hooks that can be hooked into the connecting holes, so that the ends of the springs are connected to the first and second connecting rods 150 and 160, respectively. By providing multiple first and second connecting rods 150 and 160 and a corresponding number of springs, a uniform distribution of the pressing force can be achieved. This connection method is very reliable and easy to install. In addition, preferably, the multiple springs are arranged at intervals between the base 100 and the stop plate 133, which can ensure that the pressure roller 121 evenly presses the waste, avoiding damage to the waste or unstable transportation caused by uneven pressure. In some embodiments, three spring structures are provided at both ends of the base 100 for providing continuous pressure.

[0043] In some embodiments, reference Figure 1-3One end of the base 100 is provided with a fixed plate 170, and the fixed plate 170 is perpendicular to the base 100; the fixed seat 110 is fixedly connected to the fixed plate 170, and a first bearing seat 1111 is fixed in the fixed seat 110, and the main roller 111 is connected to the first bearing seat 1111 so that the main roller 111 can rotate relative to the fixed seat 110. Specifically, there are multiple first bearings, preferably two. That is to say, one end of the main roller 111 is connected to two first bearings, which can ensure that the main roller 111 can maintain rotation stability when driven by the driving member 200. Through the arrangement of the fixed plate 170 and the first bearing seat 1111, the flexibility and stability of the rotation of the main roller 111 are improved, and the service life of the equipment is extended. In addition, in a specific embodiment, the first bearing is preferably a deep groove ball bearing. The use of deep groove ball bearings has low cost and reliable performance.

[0044] In some embodiments, reference Figure 1 Side panels 180 are provided on both sides of the base 100 in the direction in which it extends, and the side panels 180 are fixedly connected to the base 100 and the fixed plate 170, respectively. By providing the side panels 180, the structural strength and overall stability of the base 100 are enhanced. In other words, the side panels 180 can improve the deformation resistance of the base 100 and ensure the stability of the pinch roller mechanism during operation. This prevents the pressure between the main roller 111 and the pressure roller 121 from gradually decreasing as the end away from the fixed seat 110 is moved away, making the pressure between the main roller 111 and the pressure roller 121 more balanced, thereby avoiding damage to the waste or unstable transportation caused by uneven pressure. Specifically, the side panels 180 are provided on both sides of the base 100, and the height of the side panels 180 does not exceed the contact surface between the pressure roller 121 and the main roller 111. In addition, preferably, the side panels 180 are fixed to the base 100 and the fixed plate 170 at the same time by bolts or screws.

[0045] In some embodiments, reference Figure 1 、 2 Second bearing seats 122 are provided at both ends of the mounting seat 120. Both ends of the pressure roller 121 are connected to the second bearing seats 122, allowing the pressure roller 121 to rotate relative to the mounting seat 120. The second bearing seats 122 ensure the free rotation of the pressure roller 121, allowing the pressure roller 121 to flexibly adjust its position according to the waste material situation. In addition, deep groove ball bearings are preferably installed in the second bearing seats 122 to ensure the flexibility and reliability of the rotation of the pressure roller 121.

[0046] In some embodiments, reference Figure 1 、 2The driving member 200 is a motor, with a first guide pulley 210 provided at the motor's output end. A second guide pulley 1211 is provided at a position corresponding to the first guide pulley 210 on the main roller 111. The first guide pulley 210 and the second guide pulley 1211 are connected via a belt drive. The motor and belt drive achieve efficient drive of the main roller 111, while also reducing energy consumption and noise. In some embodiments, a gear drive system may also be employed.

These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
