[0038] An aluminum washing machine with a stainless steel tank body, in which support guide rollers are installed inside the caustic soda tank to provide support for the film. Guide rollers, bearings, a sealing structure and guide roller end caps are installed on the tank body to prevent the caustic soda solution from flowing out of the tank. However, since the caustic soda solution inside the caustic soda tank is corrosive, the bearings and the sealing structure need to be replaced after a period of time. Before replacement, the guide rollers need to be removed. The first step is to disassemble the guide roller end caps. Since the guide roller end caps are tightly fitted with the tank body, using manual disassembly will undoubtedly increase the labor intensity and be time-consuming and laborious.

[0039] Based on this, the present utility model provides a guide roller end cover disassembly device, which controls the rotation of the set screw through a driving assembly, and then the set screw can drive the guide roller end cover to move linearly, improving the working efficiency.

[0040] The following elaborates on the specific embodiments of the present utility model in detail in conjunction with a guide roller end cover disassembly device according to the first aspect of the present utility model.

[0041] It should be noted that a guide roller end cover disassembly device according to the first aspect of the present utility model is only a preferred embodiment of the present utility model. The guide roller end cover disassembly device of the present utility model can either adopt a guide roller end cover disassembly device according to the first aspect of the present utility model or adopt other structures. For the convenience of elaboration, the following elaborates through a guide roller end cover disassembly device according to the first aspect of the present utility model.

[0042] As Figures 1 to 5 shown, this embodiment discloses a guide roller end cover disassembly device, including a set screw 9 and a driving assembly. At least one set screw 9 is provided. The set screw 9 has a screw rod and a nut. The screw rod is threadedly fitted with a threaded hole 111 on the guide roller end cover 11, and the end of the screw rod that is not connected to the nut abuts against the groove body 10. The output end of the driving assembly is detachably connected to the set screw 9 and can drive the set screw 9 to rotate, so as to drive the guide roller end cover 11 to move linearly outward relative to the groove body 10.

[0043] For the above-mentioned guide roller end cover disassembly device, there is no need to directly rotate the set screw 9 by hand. The rotation of the set screw 9 can be directly controlled through the driving assembly, and then the set screw 9 can drive the guide roller end cover 11 to move linearly. The disassembly of the guide roller end cover 11 can be very conveniently realized, saving time and effort, and greatly improving the disassembly efficiency of the guide roller end cover 11.

[0044] It should be noted that the driving assembly in this embodiment can be a manual driving assembly or an electric driving assembly, which can be set according to actual needs.

[0045] In some embodiments, the driving assembly includes a main housing 1, a central gear 4, a driving member, a driven gear 5, and a driven shaft rod 7. The central gear 4 is rotatably disposed inside the main housing 1. The driving member is connected to the central gear 4 and is adapted to drive the central gear 4 to rotate. At least one driven gear 5 is provided. The driven gear is rotatably disposed inside the main housing 1 and meshes with the central gear 4. The driven shaft rod 7 is connected to the driven gear, and the end of the driven shaft rod 7 extends out of the main housing 1 and is connected to the nut.

[0046] In this embodiment, there is a certain distance between the two threaded holes on the guide roller end cover. Therefore, multiple gears are designed, and the multiple gears mesh with each other, that is, the multiple gears rotate in the same direction. The rotation of the central gear 4 can be controlled by an active driving member. When the central gear 4 rotates, it will drive the driven gear and the driven shaft rod 7 to rotate. Furthermore, the jackscrew connected thereto can be controlled to rotate through the driven shaft rod 7. When the jackscrew rotates, it can drive the guide roller end cover 11 to linearly move outward relative to the trough body 10.

[0047] In some embodiments, the active driving member is a central shaft rod 3. The central shaft rod 3 is rotatably arranged inside the main housing 1, and the central shaft rod 3 is fixedly connected to the central gear 4. The central gear 4 includes a gear body and a cylindrical boss integrally connected. A first threaded hole is formed in the cylindrical boss. The middle part area of the central shaft rod 3 is flattened, and a second threaded hole corresponding to the first threaded hole is formed in the flattened part of the central shaft rod 3. The central shaft rod 3 is fixedly connected to the cylindrical boss of the central gear 4 by a screw. The screw passes through the first threaded hole and is connected to the inside of the second threaded hole. In this embodiment, the central shaft rod 3 and the cylindrical boss of the central gear 4 are fixed by screw connection.

[0048] In some embodiments, one end of the central shaft rod 3 close to the guide roller end cover 11 extends out of the main housing 1 and a first retaining ring groove 31 is formed in the side wall. A first retaining ring 8 is arranged in the first retaining ring groove 31. A limiting rod is connected to the end of the central shaft rod 3 extending out of the main housing 1 (the end close to the guide roller end cover 11). The first retaining ring 8 is arranged between the limiting rod and the main housing 1, which can, to a certain extent, prevent the central shaft rod 3 from moving axially and ensure the stability of the central shaft rod 3.

[0049] In some embodiments, one end of the central shaft rod 3 away from the guide roller end cover 11 extends out of the main housing 1 and is connected with a bent rod, so that the central shaft rod 3 as a whole forms an "L" shape, that is, the central shaft rod 3 is designed as a crank type, which is convenient for the operator to hold and rotate. The end of the central shaft rod 3 away from the guide roller end cover 11 is thickened for easy hand holding.

[0050] In some embodiments, the driven gear is rotatably arranged inside the main housing 1 through a driven shaft rod 7. One end of the driven shaft rod 7 close to the guide roller end cover 11 extends out of the main housing 1 and is detachably connected to a nut. One end of the driven shaft rod 7 away from the guide roller end cover 11 extends out of the main housing 1 and is connected with a limiting column 72. The driven shaft rod 7 is designed as a straight type, and the middle part area is flattened. The driven gear includes a second gear body and a second cylindrical boss. The flattened part of the driven shaft rod 7 is fixedly connected to the second cylindrical boss by a screw.

[0051] More specifically, one end of the driven shaft rod 7 close to the guide roller end cover 11 is a hexagonal prism rod, which is adapted to the internal hexagonal hole on the nut. In this embodiment, the driven shaft rod 7 is divided into two sections, one section is a cylindrical rod, and the other section is a hexagonal prism rod. The cylindrical rod is fixedly connected to the driven gear and is rotatably arranged on the main housing 1. The hexagonal prism rod is located outside the main housing 1, which is more convenient for connecting with the internal hexagonal hole on the nut. Furthermore, when the hexagonal prism rod is inserted into the nut, it can drive the set screw to rotate.

[0052] In some embodiments, a second retaining ring groove 71 is formed on the side wall of one end of the driven shaft rod 7 close to the guide roller end cover 11. The second retaining ring groove 71 is located outside the main housing 1, and a second retaining ring 12 is arranged in the second retaining ring groove 71.

[0053] In some embodiments, the main housing 1 is a detachable housing. The main housing 1 includes a main housing body and a main housing cover plate 2. The main housing body has a structure with an open end, and the main housing cover plate 2 is covered at the opening position of the main housing body. The main housing cover plate 2 is arranged close to the guide roller end cover 11. The main housing and the main housing cover are fastened by thickening one end of the gear shaft rod and installing a retaining ring at the other end. The dimension between the thickened end of the gear shaft rod and the retaining ring is the thickness dimension of the main housing and the main housing cover.

[0054] When the specification model of the guide roller end cover 11 changes, if the position of the driven shaft rod 7 cannot be changed, it will cause the device to be unusable. To solve this technical problem, in some embodiments, adjusting holes 21 are correspondingly formed on two side walls of the main housing 1 parallel to the trough body 10. The driven shaft rod 7 can move along the adjusting holes 21 to adapt to the positioning of different specifications of the guide roller end cover 11. In this embodiment, when the specification model of the guide roller end cover 11 changes, the position of the driven shaft rod 7 can be correspondingly changed, so that the driven shaft rod 7 can still be connected to the nut on the set screw, and further the device can still be used normally.

[0055] As a preferred embodiment, two driven gears are provided, and the two driven gears are symmetrically arranged with respect to the central gear 4. In this embodiment, since the two driven gears are symmetrically arranged with respect to the central gear 4, the two driven shaft rods 7 are also symmetrically arranged with respect to the central shaft rod 3. When the central shaft rod 3 is rotated, the two driven gears can be driven to rotate simultaneously, and then the two set screws can be driven to rotate simultaneously, so that two symmetric positions on the guide roller end cover 11 move outward simultaneously, which can effectively avoid the problem that the guide roller end cover 11 is skewed due to the drive of a single set screw, and make the disassembly effect of the guide roller end cover 11 from the trough body 10 better.

[0056] Both the main housing and the main housing cover are centered around the central shaft rod hole, with the pitch circle diameter of the gear as the rotation diameter and the diameter of the driven shaft rod as the cutting clearance, cutting out a semi-circle. While ensuring gear meshing, the position of the gear shaft rod can be adjusted, thereby changing the distance between the two end central shaft rods and achieving the disassembly of end covers of different sizes. In this embodiment, the adjustment hole 21 is set in the shape of a semi-circular strip hole, so that the symmetry of the two driven gears can be ensured after adjustment, and thus it can better adapt to guide roller end covers 11 of different specifications.

[0057] The specific usage process of the above-mentioned guide roller end cover disassembly device is as follows:

[0058] Connect the driven shaft rod 7 to the nut of the setscrew 9, screw the setscrew 9 into the screw hole 111 of the guide roller end cover 11, and make the end of the setscrew 9 abut against the groove body.

[0059] Manually or by other means, rotate the central shaft rod 3. When the central shaft rod 3 rotates, it will drive the central gear 4 to rotate. The central gear 4 will drive the driven gear meshing with it to rotate, and then drive the driven shaft rod 7 and the setscrew 9 connected to the driven gear to rotate. Since the position of the groove body 10 remains unchanged, when the setscrew 9 rotates, it will drive the guide roller end cover 11 to linearly move outward, achieving the purpose of disassembling the guide roller end cover.

[0060] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the creation of the present utility model.
