[0003]然而,现有的布草折叠机因为台面电机需要不断的启动停止(急停),在长时间的使用过程中,电机安装座与机架之间的连接会发生大量的磨损,造成极大的旷量,在电机工作的时候会有顺时针或逆时针撞击的情况,不但造成很大的噪音,对电机的使用寿命也会有影响,又因为旷量变大,导致撞击的情况更加严重,如此反复死循环
[0014] 1. This technical solution replaces the existing rigid clearance structure with a movable joint and a backlash-free rotating connection. The tight fit between the joint bearing and the connecting rod, fixed shaft, and mounting base eliminates the clearance between components. Furthermore, the mounting plate is fixed to the right-angle motor with multiple screws around its perimeter, and the mounting plate's rotating holes are inserted into the fixed shaft, further eliminating localized minor clearances. When the roller shaft head jumps due to motor start-up or sudden stop, the movable joint absorbs the displacement through double rotation to compensate, eliminating any impact phenomenon. This not only eliminates impact noise but also avoids additional wear on the motor caused by impact forces, significantly extending the motor's service life.

Abstract
Description
Technical Field
[0001] This application relates to the field of washing equipment technology, specifically to a countertop motor fixing device. Background Technology
[0002] A linen folding machine is a specialized piece of equipment used in hotels, hospitals, nursing homes, large-scale laundry facilities, and other venues to automatically fold cleaned and dried linens such as sheets, duvet covers, pillowcases, towels, bath towels, and tablecloths. It is one of the core pieces of equipment in the linen cleaning and disinfection process. Its main function is to replace traditional manual folding. The machine conveys the processed, flat linens into the machine via a conveyor mechanism, and accurately completes folding operations of different specifications, such as single folds, double folds, and multiple folds, according to a preset program. This not only significantly improves the efficiency of linen folding but also ensures the consistency and regularity of the folded size of each piece of linen, reducing the intensity and cost of manual labor.
[0003] However, existing linen folding machines require the table motor to be constantly started and stopped (emergency stop). During long-term use, the connection between the motor mounting base and the frame will experience a lot of wear, resulting in a large amount of play. When the motor is working, there will be clockwise or counterclockwise impacts, which not only cause a lot of noise, but also affect the service life of the motor. Because of the increased play, the impacts become more severe, and so on in a vicious cycle. Utility Model Content
[0004] The purpose of this invention is to provide a tabletop motor fixing device to solve the problems mentioned in the background art.
[0005] The technical solution adopted by this application to solve its technical problem is:
[0006] A tabletop motor fixing device includes a right-angle motor, a mounting plate, a movable joint, and a mounting base. The side end face of the right-angle motor is fixedly installed to the mounting plate by screws. The top of the mounting plate is rotatably installed to one end of the movable joint, and the other end of the movable joint is rotatably installed to the mounting base.
[0007] The movable joint includes a first joint bearing, a connecting rod, and a second joint bearing. One end of the connecting rod is installed with the first joint bearing, and the other end of the connecting rod is installed with the second joint bearing. The first joint bearing is rotatably installed with the mounting plate via a fixed shaft, and the interior of the second joint bearing is rotatably installed with the mounting base.
[0008] Preferably, both ends of the connecting rod are provided with threaded portions, which are respectively connected to the internal threads of the first joint bearing and the second joint bearing.
[0009] Preferably, the mounting plate has an output shaft hole in the middle for the drive shaft of the right-angle motor to extend out, and mounting holes are provided around the perimeter of the mounting plate. The mounting plate is fixedly mounted on the side end face of the right-angle motor through the mounting holes and screws.
[0010] Preferably, the top of the mounting plate has a rotating hole, and the inside of the rotating hole is inserted into the fixed shaft for installation.
[0011] Preferably, the mounting base includes a shaft and a nut, the shaft being internally inserted into the second joint bearing, and the nut being threaded to the side wall of the shaft.
[0012] Preferably, the movable joint is inclined to the right-angle motor.
[0013] The beneficial effects of this application are:
[0014] 1. This technical solution replaces the existing rigid clearance structure with a movable joint and a backlash-free rotating connection. The tight fit between the joint bearing and the connecting rod, fixed shaft, and mounting base eliminates the clearance between components. Furthermore, the mounting plate is fixed to the right-angle motor with multiple screws around its perimeter, and the mounting plate's rotating holes are inserted into the fixed shaft, further eliminating localized minor clearances. When the roller shaft head jumps due to motor start-up or sudden stop, the movable joint absorbs the displacement through double rotation to compensate, eliminating any impact phenomenon. This not only eliminates impact noise but also avoids additional wear on the motor caused by impact forces, significantly extending the motor's service life.
[0015] 2. This technical solution can achieve flexible rotation in multiple angles and directions through the double joint bearing of the movable joint, which can fully match the irregular runout of the roller shaft head such as radial and slight axial movements. With the tilt setting of the movable joint and the motor, displacement can be efficiently absorbed through a shorter rotation stroke, avoiding the force resistance of vertical setting, and ensuring that the coaxial transmission of the motor drive shaft and the roller shaft head is not affected.

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0033] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present application.
[0034] Please see Figure 1-3 The embodiments provided by this utility model are as follows:
[0035] The tabletop motor fixing device includes a right-angle motor 3, a mounting plate 4, a movable joint, and a mounting base 8. The side end face of the right-angle motor 3 is fixedly installed to the mounting plate 4 by screws. The top of the mounting plate 4 is rotatably installed to one end of the movable joint, and the other end of the movable joint is rotatably installed to the mounting base 8. The mounting base 8 is fixedly installed on the frame 1 of the folding machine.
[0036] The overall structure consists of a frame 1, a mounting base 8, a movable joint, a mounting plate 4, and a right-angle motor 3. The mounting base 8 is fixed on the frame 1, providing a stable reference for the entire device. The movable joint flexibly connects the mounting plate 4 and the mounting base 8 through a rotating connection at both ends, whereas the existing structure has a rigid connection with gaps.
[0037] When the right-angle motor 3 starts or stops suddenly, the roller shaft head will jump due to processing. The drive shaft of the right-angle motor 3 will drive itself to produce a small displacement. This displacement is transmitted to the movable joint through the mounting plate 4. The movable joint absorbs the displacement by rotating itself, thereby achieving jump compensation.
[0038] Meanwhile, since there is no clearance between the movable joint and the rotating connection of the mounting plate 4 and the mounting base 8, there will be no clockwise or counterclockwise impact when the motor is running.
[0039] The movable joint includes a first joint bearing 5, a connecting rod 6, and a second joint bearing 7. One end of the connecting rod 6 is installed with the first joint bearing 5, and the other end of the connecting rod 6 is installed with the second joint bearing 7. The first joint bearing 5 is rotatably installed with the mounting plate 4 via a fixed shaft 9, and the interior of the second joint bearing 7 is rotatably installed with the mounting base 8.
[0040] The movable joint forms a flexible transmission structure through two joint bearings and a connecting rod 6. Compared with ordinary bearings, joint bearings can achieve flexible rotation in multiple angles and directions, and can more comprehensively match the displacement direction of the irregular jumping of the roller head, such as radial and slight axial offset. When the roller head jumps, the motor displacement is transmitted to the first joint bearing 5 through the mounting plate 4, and the first joint bearing 5 rotates around the fixed shaft 9.
[0041] Meanwhile, the second joint bearing 7 rotates around the mounting base 8, and the connecting rod 6 adjusts its angle with the rotation of the two joint bearings, forming a double rotational compensation to completely absorb the runout displacement. Furthermore, the joint bearings are in close fit with the connecting rod 6, the fixed shaft 9, and the mounting base 8, so that the motor will not experience impacts due to loose parts during operation, and at the same time, it will avoid the occurrence of play due to loose structure.
[0042] Furthermore, both ends of the connecting rod 6 are provided with threaded portions 61, which are respectively connected to the internal threads of the first spherical bearing 5 and the second spherical bearing 7. During installation, by rotating the connecting rod 6, the threaded portions 61 are tightly engaged with the internal threads of the spherical bearings, which can completely eliminate the fit clearance between the connecting rod 6 and the spherical bearings. When the motor starts and stops suddenly, the threaded connection can withstand the impact force of the motor, avoiding loosening between components due to the impact force, and thus preventing play. At the same time, the detachability of the threaded connection can also improve the convenience of installation and disassembly.
[0043] The mounting plate 4 has an output shaft hole 41 in the middle for the drive shaft of the right-angle motor 3 to extend out. The drive shaft of the right-angle motor 3 is directly mounted on the roller shaft of the folding device 2. The folding device 2 of the folding machine drives the transmission belt to move the linen by rotating the roller. The output shaft hole 41 provides precise guidance for the motor drive shaft, ensuring that the drive shaft can be coaxially connected to the roller shaft, and avoiding additional wear caused by misalignment between the drive shaft and the roller shaft.
[0044] Mounting plate 4 has mounting holes 42 on all four sides. Mounting plate 4 is fixed to the side end face of right angle motor 3 through mounting holes 42 and screws. The mounting holes 42 on all four sides are fixed with screws, forming a multi-point uniform fixing structure, so that the side end face of motor and mounting plate 4 are fully in contact, eliminating the tiny gap between the two.
[0045] It is worth noting that the top of the mounting plate 4 has a rotating hole 43, and the inside of the rotating hole 43 is inserted into the fixed shaft 9 to ensure that the mounting plate 4 can rotate flexibly around the fixed shaft 9, providing a rotation path for runout compensation, while avoiding jamming or radial loosening during rotation.
[0046] It is worth noting that the mounting base 8 includes a shaft 81 and a nut 82. The shaft 81 is internally inserted into the second spherical bearing 7, and the nut 82 is threaded into the side wall of the shaft 81, providing a rotation shaft for the second spherical bearing 7. This ensures that the spherical bearing can rotate flexibly around the shaft 81, and the insertion fit is gapless, preventing axial movement during rotation. At the same time, tightening the nut 82 axially positions the second spherical bearing 7, preventing the spherical bearing from moving on the shaft 81, ensuring the overall structural stability of the movable joint, and preventing impact caused by the spherical bearing moving during motor operation.
[0047] It is worth noting that the movable joint and the right-angle motor 3 are set at an angle. The angled setting makes the rotation plane of the movable joint more matched with the displacement direction of the motor affected by the jump. The angled movable joint can absorb the displacement through a shorter rotation stroke, avoid the force confrontation when set vertically, disperse the impact force when the motor starts or stops suddenly, avoid the impact force being concentrated at a certain point of the movable joint, reduce local wear, and extend the service life of the joint bearing and the connecting rod 6.
[0048] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
