[0038] 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.

[0039] 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.

[0040] Please see Figure 1-6 The embodiments provided by this utility model are as follows:

[0041] A brushing mechanism for a linen spreading machine is disclosed. The brushing mechanism is installed in the linen passageway inside the linen spreading machine. The brushing mechanism includes a support frame 1, which is fixedly mounted on the inner sidewall of the linen spreading machine at both ends. Two sets of guide frames 2 are provided above the support frame 1, and both sets of guide frames 2 are fixedly mounted to the sidewalls of a guide cover 3. A sliding roller 31 for conveying linen is rotatably connected to the bottom surface of the guide cover 3. The sliding roller 31 on the bottom surface of the guide cover 3 is rotatably connected to the guide cover 3 via bearings. When the linen enters the brushing mechanism under the power drive of the spreading machine, the sliding roller 31 can rotate smoothly, reducing friction during the linen movement and guiding the linen smoothly through the brushing area along a preset path.

[0042] The guide frame 2 is equipped with an inner brush assembly for cleaning one side of the linen. The inner brush assembly includes a first driven wheel 21, a first driving wheel 22, an inner brush cloth 23, a first gearbox 24, and a second drive motor 44. The two ends of the guide frame 2 are rotatably connected to the first driven wheel 21 and the first driving wheel 22 respectively through bearings. The first driving wheel 22 and the first driven wheel 21 are connected by transmission through the inner brush cloth 23. The outer side of the guide frame 2 is fixedly installed with the first gearbox 24. The input shaft of the first gearbox 24 is installed with the output shaft of the first drive motor 25. The output shaft of the first gearbox 24 is fixedly installed with the shaft of the first driving wheel 22. The surface of the inner brush cloth 23 is provided with air holes.

[0043] After the second drive motor 44 starts, its output shaft transmits power to the first gearbox 24. The first gearbox 24 adjusts the motor's speed and torque to meet the working requirements of the inner brush cloth 23, and then transmits the adjusted power to the shaft of the first drive wheel 22. The first drive wheel 22 and the first driven wheel 21 are mounted at both ends of the guide frame 2 via bearings. When the first drive wheel 22 rotates under the drive of the first gearbox 24, it drives the inner brush cloth 23 to move. The inner brush cloth 23 achieves cyclic operation through its transmission connection with the first drive wheel 22 and the first driven wheel 21. The surface of the inner brush cloth 23 has through-holes. When the inner brush cloth 23 moves, it cleans one side of the linen by contacting and moving relative to it.

[0044] The inner brush 23 is cleaned by brushing one side of the linen. Through the power transmission and speed change of the motor and gearbox, the inner brush 23 has the appropriate speed and force to effectively remove wrinkles and debris from the surface of the linen. The design of the air holes helps airflow or dust suction, providing better results for the cleaning process.

[0045] A collection component 8 is fixedly installed on the side wall of the guide frame 2. The collection component 8 includes a collection chamber 81 and a collection pipe 82. The collection chamber 81 is installed on the side wall of the guide frame 2, and the opening of the collection chamber 81 faces the inner brush cloth 23. The collection pipe 82 is fixedly installed on the side wall of the collection chamber 81 and is internally connected. During the brushing process, as the inner brush cloth 23 cleans the linen, any dust, debris, etc. that may be generated are cleaned up and guided into the collection chamber 81 through the collection pipe 82 connected to the vacuum cleaner. Then, the debris is discharged or collected through the collection pipe 82 to keep the brushing area clean and prevent waste from re-contaminating the linen or affecting the brushing effect.

[0046] The top surface of the guide frame 2 is equipped with an external brush assembly 4 for cleaning the other side of the linen via a sliding assembly 5. The sliding assembly 5 is driven by a rotating assembly 6 to reciprocate on the guide frame 2.

[0047] The sliding assembly 5 includes a connecting plate 51, a support plate 52, a slide block 53, and a guide rail 54. One end of the connecting plate 51 is fixedly installed on the rotating assembly 6, and the other end of the connecting plate 51 is fixedly installed on the support plate 52. The top surface of the slide block 53 is fixedly installed on the support plate 52. The guide rail 54 is fixedly installed on the top surface of the guide frame 2. The slide block 53 is slidably connected to the side wall of the guide rail 54. The rotating assembly 6 includes a synchronous wheel 61, a guide wheel 62, and a synchronous belt 63. The outer side of the guide frame 2 is rotatably connected to the synchronous wheel 61 and the guide wheel 62 through bearings, respectively. The two synchronous wheels 61 are connected by a synchronous belt 63. One end of the connecting plate 51 is fixedly installed on the side wall of the synchronous belt 63. The guide wheel 62 is installed close to the synchronous wheel 61, and the synchronous belt 63 is wrapped around the side wall of the guide wheel 62. One of the synchronous wheels 61 is connected to a drive motor with a gearbox through a shaft.

[0048] In the rotating assembly 6, the synchronous pulley 61 and guide pulley 62 on the outer side of the guide frame 2 rotate through bearings. One of the synchronous pulleys 61 is driven by a drive motor with a gearbox. The power output by the motor is transmitted to the synchronous pulley 61 after being adjusted by the gearbox, which drives the synchronous belt 63 to move. When the synchronous belt 63 moves, since one end of the connecting plate 51 is fixed to the side wall of the synchronous belt 63, and the other end of the connecting plate 51 is fixed to the support plate 52, and the support plate 52 is fixed to the slide 53, and the slide 53 slides on the guide rail 54, the movement of the synchronous belt 63 drives the slide 53 to move back and forth on the guide rail 54, thereby driving the outer brush assembly 4 to adjust its position on the inner brush assembly.

[0049] The inner brush assembly and the outer brush assembly 4 are arranged opposite to each other. The outer brush assembly 4 includes a cylinder 41, a mounting cover 42, a second gearbox 43, a second drive motor 44, a second drive wheel 45, a second driven wheel 46, and an outer brush cloth 47. The cylinder 41 is fixedly mounted on the top surface of the support plate 52. The piston rod end of the cylinder 41 is fixedly mounted to the side wall of the mounting cover 42. The two sides inside the mounting cover 42 are rotatably connected to the second drive wheel 45 and the second driven wheel 46 respectively through bearings. The second drive wheel 45 and the second driven wheel 46 are connected by transmission through the outer brush cloth 47. The second gearbox 43 is fixedly mounted on the top surface of the mounting cover 42. The output shaft of the second drive motor 44 is fixedly mounted to the input shaft of the gearbox. The output shaft of the gearbox is fixedly mounted to the shaft of the second drive wheel 45.

[0050] The output shaft of the second drive motor 44 transmits power to the second gearbox 43. The second gearbox 43 adjusts the power and then transmits it to the shaft of the second drive wheel 45, causing the second drive wheel 45 to rotate. The second drive wheel 45 and the second driven wheel 46 are mounted on both sides inside the mounting cover 42 through bearings. When the second drive wheel 45 rotates, it drives the outer brush cloth 47 to move. The piston rod of the cylinder 41 can extend and retract to adjust the position of the mounting cover 42, thereby adjusting the distance between the outer brush cloth 47 and the linen to adapt to the brushing needs of linen of different thicknesses or conditions, and to clean the other side of the linen. The adjustment of the cylinder 41 can ensure that the contact pressure with the surface of the linen is appropriate. Combined with the movement of the outer brush cloth 47, the wrinkles and debris on the other side of the linen can be effectively cleaned.

[0051] The bottom two sides of the support frame 1 are respectively equipped with a fabric smoothing component for smoothing the linen. The fabric smoothing component includes a thumb cylinder 7 and a gripper 71. The thumb cylinder 7 is fixedly installed on both sides of the bottom surface of the support frame 1, and the thumb on the thumb cylinder 7 is fixedly installed with the gripper 71.

[0052] Thumb cylinders 7 are installed on both sides of the bottom surface of the support frame 1. When the thumb cylinders 7 are activated, they can drive the thumb and gripper 71 to move. The thumb and gripper 71 are fixedly installed and can smooth the linen under the drive of the thumb cylinders 7. This smoothing operation is achieved by opening and closing the gripper 71. Before the linen is cleaned by the inner brush assembly and the outer brush assembly 4, the smoothing operation is performed to further improve the flatness of the linen and ensure that the linen can achieve a better spreading effect after passing through the brushing mechanism, reducing wrinkles and preparing for subsequent processes.

[0053] 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.
