[0002] The applicant's application for CN223201276U, a material clamping and conveying assembly, has been found to have the following drawbacks during actual use: although the clamping assembly can apply clamping force to the middle section of the driven roller, its fixed position makes it inconvenient to move when it needs to be precisely positioned and adjusted to the clamping position according to the actual production situation; and the length of the clamping roller is fixed, making it impossible to expand the clamping range of the driven roller according to the actual production situation.

[0003] Therefore, it is necessary to improve the thin-film transport components in the existing technology. Utility Model Content

[0004] The purpose of this invention is to overcome the defects in the existing technology and provide a film transport component that can adjust the position of the clamping component and the length of the clamping roller according to actual production needs, so as to ensure the adhesion between the driven roller and the driving roller, thereby ensuring the normal transport of the film.

[0005] To achieve the above technical effects, the technical solution of this utility model is as follows: a thin film transport assembly, including a frame, a driving roller and a driven roller rotatably connected to the frame, and two sets of clamping assemblies. The clamping assemblies are used to press the driven roller against the driving roller. An adjusting assembly for adjusting the position of the clamping assemblies is provided between the two sets of clamping assemblies and the frame. A crossbeam is fixedly provided on the frame.

[0006] According to one embodiment of the present invention, the clamping assembly further includes a mounting base connected to the mounting bracket, and a clamping roller is rotatably disposed below the mounting base. The rotation axis of the clamping roller is parallel to the axis of the driven roller, and two clamping rollers are disposed along a direction perpendicular to the axis of the driven roller.

[0010] According to one embodiment of the present invention, an auxiliary abutting component is further included, which is detachably and fixedly connected to the mounting base.

[0015] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0016] In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "horizontal," "vertical," "top," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used solely for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Example

[0017] like Figure 1-4 As shown, the thin film transport assembly of this embodiment includes a frame 1, a drive roller 2 and a driven roller 3 rotatably connected to the frame 1, and two sets of clamping components 4. The clamping components 4 are used to press the driven roller 3 against the drive roller 2. An adjusting component for adjusting the position of the clamping components 4 is provided between the two sets of clamping components 4 and the frame 1. A crossbeam 11 is fixedly provided on the frame 1. The clamping components 4 include mounting brackets 41, and the mounting brackets 41 are provided with a sliding groove 411 that is slidably connected to the crossbeam 11. The adjusting component includes a screw 7 rotatably connected to the frame 1 and a motor 6 that drives the screw 7 to rotate. The screw 7 is provided with two threaded sections with opposite directions of rotation. The two mounting brackets 41 are respectively threadedly connected to the two threaded sections.

[0018] This design allows for flexible adjustment of the clamping position to adapt to different production needs: the adjustment components work in conjunction with the sliding grooves and crossbeams of the mounting brackets. When the motor drives the screw to rotate, the two mounting brackets slide in opposite directions along the crossbeam because the two ends of the screw's threads rotate in opposite directions, thus precisely adjusting the spacing and position of the two sets of clamping components. This design eliminates the need for manual disassembly and adjustment, enabling rapid adaptation to film production scenarios with different transmission requirements.

[0019] The adjustment process is stable and precise, reducing the difficulty of operation: The mounting bracket is slidably connected to the frame beam through a slide groove, providing a stable guide for the movement of the clamping component. Combined with the motor-driven screw adjustment, it avoids positional deviations during manual adjustment, which not only improves the adjustment accuracy but also reduces the difficulty of operation for operators and improves production efficiency.

[0020] According to one embodiment of the present invention, the clamping assembly 4 further includes a mounting base 42 connected to the mounting bracket 41. A clamping roller 43 is rotatably disposed below the mounting base 42. The rotation axis of the clamping roller 43 is parallel to the axis of the driven roller 3. Two clamping rollers 43 are disposed along a direction perpendicular to the axis of the driven roller 3.

[0021] This design, with its double-coupling rollers, achieves uniform force distribution and prevents localized misalignment of the driven roller. The two coupling rollers can simultaneously apply coupling force to the driven roller from different positions. Compared to single-roller coupling, this design can distribute pressure and ensure that the driven roller and the driving roller fit together tightly, reducing slippage and wrinkling problems caused by uneven roller fit during film transport.

[0022] According to one embodiment of the present invention, a lifting assembly for pressing the clamping roller 43 against the driven roller 3 is provided between the mounting bracket 41 and the mounting base 42.

[0023] This design provides controllable clamping force to ensure tight fit between the rollers: the lifting assembly can output a continuous and adjustable vertical force to push the mounting base and the clamping roller below to press precisely against the driven roller, so that the driven roller and the driving roller always maintain a tight fit, thus avoiding slippage between the two rollers, film transport deviation or wrinkles caused by insufficient clamping force.

[0024] According to one embodiment of the present invention, the lifting assembly includes a cylinder 44, the cylinder body of the cylinder 44 is fixedly connected to the mounting bracket 41, the piston rod of the cylinder 44 is fixedly connected to the mounting base 42, and the extension and retraction direction of the piston rod of the cylinder 44 is vertically arranged.

[0025] According to one embodiment of the present invention, the driven roller 3 is disposed above the driving roller 2, and the driven roller 3 is sandwiched between the driving roller 2 and the pressing roller 43.

[0026] This design creates a clamping force from above and below, ensuring a tight fit between the two rollers: the clamping roller applies pressure from above, the driving roller supports from below, and when the driven roller is sandwiched in the middle, the downward pressure of the clamping roller can directly act on the driven roller, forcing the contact surfaces of the driven roller and the driving roller to fit completely together. This avoids the problem of localized poor fit caused by the dispersion of force direction, and structurally eliminates slippage and deviation during film transport.

[0027] According to one embodiment of the present invention, it further includes an auxiliary abutting component 5 that is detachably and fixedly connected to the mounting base 42. The auxiliary abutting component 5 includes an auxiliary seat 51 and an auxiliary abutting roller 52 that is rotatably connected to the auxiliary seat 51. The auxiliary seat 51 is connected to the mounting base 42.

[0028] This design allows for disassembly and assembly as needed, reducing equipment downtime costs: the "detachable fixed connection" design allows for direct removal when the production environment does not require expanding the clamping range, without occupying additional equipment space; it only needs to be installed when required, avoiding a decrease in equipment adaptability due to fixed additions and reducing unnecessary waste of idle parts.

[0029] According to one embodiment of the present invention, the mounting base 42 is provided with a slot 421, and two slots 421 are respectively disposed on both sides of the clamping roller 43. The auxiliary base 51 is inserted and connected to the slot 421. An elastic protrusion 511 and a groove 422 that limit and cooperate with each other are provided between the side wall of the auxiliary base 51 and the side wall of the slot 421.

[0030] This design enables quick assembly and disassembly, improving operational efficiency: the auxiliary seat and the mounting seat are connected by a slot, eliminating the need for bolts, wrenches, or other tools. Assembly and disassembly can be completed simply by inserting or removing the auxiliary seat into the slot.

[0031] According to one embodiment of the present invention, the cylinder 44 is slidably connected to the mounting bracket 41, the sliding direction of the cylinder 44 is perpendicular to the axis of the driven roller 3, and the cylinder 44 and the mounting bracket 41 are fixedly connected by bolts.

[0032] With this design, the position of the pressing roller on the driven roller can be precisely adjusted by the sliding cylinder, ensuring that the pressing roller and the driven roller are in contact.

[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
