Description

Technical Field

[0001] This utility model relates to the field of sheet material conveying, specifically an adjustable guide roller assembly mechanism. Background Technology

[0002] In the production and processing of large sheet materials such as filter membranes, the sheet conveying is continuous and needs to be carried out throughout all production stages from unwinding. This includes necessary steps such as drying, curing, and coating. Each process stage corresponds to specific processing equipment. For example, the curing equipment is a sealed box in which the sheet enters from one end and exits from the other, where it undergoes film formation and curing.

[0003] Such long-distance transport involving multiple devices, with variations in distance and height between equipment and production stages, can easily lead to uneven tension in the sheet material during transport. For example, if the sheet tension is too low before entering the drying equipment, wrinkles may appear during drying; if the tension is too high, the sheet may stretch and deform, affecting product quality. Furthermore, film manufacturers are often constrained by factory space when arranging equipment, making it difficult to achieve a perfect match between equipment positions. For instance, the distance between the drying equipment and subsequent cooling equipment may be significant, and their heights may also differ. During transport, the sheet material may experience misalignment, shaking, or damage due to excessive impact from significant height differences between equipment.

[0004] Under the above circumstances, it is best to sort the sheets before they enter the equipment and after they are discharged from the production line, especially at some key locations, such as the inlet and outlet of the drying equipment. Currently, individual guide rollers are hung at the inlet and outlet of the equipment, and the sheets are sorted by the rollers close to the inlet and outlet. However, the guide rollers are now single or double rollers, which can only adjust the roller spacing and the distance from the inlet and outlet. The height of the rollers cannot be adjusted, which makes it very difficult to adjust the tension of the sheets and the height difference of the sheets. Utility Model Content

[0005] The purpose of this utility model is to provide an adjustable guide roller assembly mechanism, which is installed at the inlet and outlet of sheet processing equipment to flexibly and adjustably guide and support the sheets entering and leaving the equipment.

The pin is movably connected to the pin holes to achieve locking. The pin is a spring pin or an electromagnetic pin. The pin is installed on the side of the outer swing arm near the inner swing arm. The limiting plate is set on the first sliding sleeve.

[0010] A first power mechanism is provided between the swing seat and the inner swing arm, and the first power mechanism is used to drive the swing of the inner swing arm relative to the swing seat. A second power mechanism is provided between the first sliding sleeve and the outer swing arm, and the second power mechanism is used to drive the swing between the first sliding sleeve and the outer swing arm. The first power mechanism and the second power mechanism include any one of a stepper motor, a pneumatic cylinder, a hydraulic cylinder, and an electric cylinder.

[0011] The mounting frame includes a horizontal plate located on the bottom side, with vertical plates fixed to both ends of the horizontal plate, and the horizontal plate and vertical plates are in a "U" shape.

[0012] A first grooved plate is fixed on the first sliding sleeve, and a first threaded sleeve is fixed at the bottom of the first grooved plate.

Detailed Implementation

[0024] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0025] This guide roller assembly is externally fixed and installed at the inlet and outlet of sheet processing equipment to guide and support the sheets entering and leaving the equipment. Its main structure includes: Mounting frame, inner swing arm 6, outer swing arm 8, inner roller 15, outer roller 16.

[0026] The mounting frame has a U-shaped structure. The mounting frame includes a horizontal plate 1 located on the bottom side. Vertical plates 2 are fixed to both ends of the horizontal plate 1. The horizontal plate 1 and the vertical plates 2 form a "U" shape to facilitate the opening and closing of the equipment and fix it below the opening and closing. The vertical plates 2 and the horizontal plate 1 are fixed by bolts.

[0027] The upright plate 2 is provided with a swing seat 3, and an inner swing arm 6 is rotatably connected to the swing seat 3. Specifically, the swing seat 3 has a downwardly penetrating semi-through groove, and a shaft is fixed in the semi-through groove. One end of the inner swing arm 6 is rotatably connected to the shaft. The swing seat 3 is provided with a protruding semi-circular limiting plate 4, and multiple pin holes 5 are arranged in a ring around the shaft. The end of the inner swing arm 6 near the swing seat 3 is provided with a spring pin or an electromagnetic pin, which is movably connected to the pin holes 5 to fix the swing angle of the inner swing arm 6.

[0028] Not limited to this example, other structures can also be used to adjust and fix the angle of the inner swing arm, including but not limited to the following examples: A cylinder is hinged to the bottom of the upright plate 2. The top of the cylinder extends and retracts to engage with the cylinder rod. The top of the cylinder rod is hinged to the inner swing arm 6 near the swing seat 3. The angle of the inner swing arm 6 is automatically controlled by the extension and retraction of the cylinder.

[0029] The shaft is rotatably mounted to the swing seat 3 and fixed to the inner swing arm 6. A motor is also fixed on the upright plate 2 or the swing seat 3. The output shaft of the motor is connected to the shaft for transmission, so as to realize direct control of the swing angle.

[0030] The inner swing arm 6 is fitted with a first sliding sleeve 7 that slides along its length. An outer swing arm 8 is hinged to the first sliding sleeve 7. The length of the outer swing arm 8 is preferably less than that of the inner swing arm 6 to avoid excessive load.

[0031] For limiting the position of the first sliding sleeve 7 relative to the inner swing arm 6, the following structure can be referenced: A first grooved plate 9 is fixed to the first sliding sleeve 7 by bolts. A first threaded sleeve 10 is fixed to the bottom of the first grooved plate 9. The first threaded sleeve 10 extends vertically relative to the inner swing arm 6 and is located below the inner swing arm 6. The first threaded sleeve 10 is eccentrically positioned on the side of the first sliding sleeve 7 near the swing seat 3. A first fastening bolt is threaded through the first threaded sleeve 10 from bottom to top. The top of the first fastening bolt can fix the first sliding sleeve 7 in position by abutting against the bottom surface of the inner swing arm 6. Alternatively, slots 11 can be equidistantly provided on the bottom surface of the inner swing arm 6. The slots 11 and the first fastening bolt cooperate to achieve a more reliable fixation of the first sliding sleeve 7.

[0032] The swing angle control of the outer swing arm 8 can be achieved by using the same structure as the inner swing arm 6, or by using different structures.

[0033] If the same structure is used, a limiting plate 4 with a pin hole 5 can be provided on the first sliding sleeve 7 or the first groove plate 9, and a spring pin or electromagnetic pin can be provided at the root of the outer swing arm 8.

[0034] Other fixed inner swing arm 6-degree automatic or manual structures can also be used, as exemplified above.

[0035] The inner swing arm 6 and the outer swing arm 8 have the same cross-section, but different lengths, which facilitates the unification of the roller structure and the processing and production. At least one roller module is provided between the two inner swing arms 6 and between the two outer swing arms 8. The roller module includes: a second sliding sleeve 12 and a roller.

[0036] The second sliding sleeve 12 is slidably sleeved on the inner swing arm 6 or the outer swing arm 8. A second grooved plate 13 is fixed to the second sliding sleeve 12 by bolts. The bottom of the second grooved plate 13 extends to both sides along the length of the second sliding sleeve 12, so that the second threaded sleeve 14 can be located below the inner swing arm 6 or the outer swing arm 8. Two second threaded sleeves 14 are symmetrically provided at the bottom of the second grooved plate 13. The second threaded sleeves 14 are respectively located on both sides of the second sliding sleeve 12 and below the inner swing arm 6 or the outer swing arm 8. The second threaded sleeves 14 are perpendicular to the second sliding sleeve 12. A second fastening bolt with threaded engagement is passed through the second threaded sleeve 14 from bottom to top. The top of the second fastening bolt can fix the second sliding sleeve 12 by pressing against the bottom surface of the inner swing arm 6 or the outer swing arm 8. Alternatively, slots 11 can be provided at equal intervals on the bottom surfaces of the inner swing arm 6 and the outer swing arm 8. The slots 11 and the first / second fastening bolts cooperate to achieve a more reliable fixation of the first sliding sleeve 7. A slot 11 is used to secure both the first and second fastening bolts, enabling modular structure and assembly.

[0037] Based on the distance from the equipment entrance and exit, the inner side is defined as the side closer to the equipment (i.e., the mounting frame), and the outer side is defined as the side farther away. Therefore, the inner rollers 15 installed between the inner swing arms 6 and the outer rollers 16 installed between the outer swing arms 8 can be defined as the inner rollers 15 and 1-3 outer rollers 16. One is recommended to be sufficient. Only the spacing between the inner rollers 15 and the outer rollers 16 can be adjusted. The spacing between the inner rollers 15 and the outer rollers 16 can be flexibly adjusted based on the swing position relationship between the inner swing arms 6 and the outer swing arms 8. The inner rollers 15 and the outer rollers 16 can be made horizontal and the spacing can be freely adjusted. The height of the inner rollers 15 and the outer rollers 16 relative to the equipment entrance and exit can also be adjusted. The vertical position and height difference of the inner rollers 15 and the outer rollers 16 can also be flexibly controlled, thereby guiding the sheets entering and exiting the equipment as needed and realizing tension adjustment.

[0038] Given the high flexibility of this application, the following are some simple examples of different states for ease of understanding: like Figure 5 As shown, the inner roller 15 and the outer roller 16 are of the same height and are located outside the inlet and outlet. Their height and distance are adjustable.

[0039] like Figure 4 As shown, the inner roller 15 is at the bottom and the outer roller 16 is at the top, and the height difference and distance between the two are adjustable. like Figure 6 As shown, the inner roller 15 is on top and the outer roller 16 is on the bottom. The height difference and distance between the two are adjustable.

[0040] The outer swing arm 8 and the inner swing arm 6 are respectively connected by outer end bolts, which prevent the sliding parts mating with them from disengaging. Furthermore, by removing the outer end bolts, easy disassembly and assembly can be achieved, allowing for component replacement or free combination. This enables the mechanism to be adapted into various combinations and forms beyond what is described in this example.

[0041] This mechanism, installed outside the equipment inlet and outlet, provides an adjustable distance and height between the inlet and outlet, as well as an adjustable spacing, relative position, and relative height of (at least) two rollers. This dual-roller guide assembly can be flexibly adjusted according to the sheet production process, equipment layout, and sheet tension. For example, when increased tension is required, the height difference between the two guide rollers can be appropriately increased, allowing the sheet to generate a certain tensile force under gravity and its own elasticity, thus achieving a suitable tension state. Similarly, when the distance to the docking equipment is large, the spacing between the guide rollers can be increased to guide the sheet, preventing sagging or shaking during transport due to excessive span. This dual-roller guide assembly offers a wide range of adjustable dimensions, and this flexible adjustment method can well adapt to the precise transport requirements of different production scenarios, assisting in the smooth and stable transition of sheets into and out of the equipment.
