Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] The following will combine Figures 1-5 A detailed description of a polyester-cotton fabric printing and dyeing pretreatment device according to an embodiment of the present invention is provided.

[0024] Example:

[0025] This utility model provides a pretreatment device for printing and dyeing polyester-cotton fabric, which is referenced in the following embodiment. Figures 1 to 5 As shown, the device includes a base frame 1, on which a pretreatment box 2 for polyester-cotton fabric printing and dyeing is mounted. Two shafts 3 are parallel to each other in the center of the pretreatment box's interior cavity. The two shafts 3 are rotatably mounted on the pretreatment box 2. A baffle 4 is fixedly connected to one side of each shaft 3. A sleeve 5 is fitted onto each shaft 3, and brushes 6 are evenly connected to the sleeve 5. A locking nut 7 is threaded onto the other side of each shaft 3. Gears 8 are fixedly connected to the same side of both shafts 3, and the gears 8 on the two shafts 3 mesh with each other. A bracket 9 is fixedly connected to the outer wall of the pretreatment box 2, and a drive motor 10 is fixedly connected to the bracket 9. The output shaft of the drive motor 10 is connected to one of the shafts 3. The pretreatment box 2 is provided with an inspection port 11. The outside of the inspection port 11 is provided with a sealing plate 12. The sealing plate 12 is detachably and sealed on the outer wall of the pretreatment box 2 by bolts. In this structure, the polyester-cotton fabric is conveyed from top to bottom. At this time, the drive motor 10 drives one of the shafts 3 to rotate. The shaft 3 drives the other shaft 3 to rotate through the gear 8, thereby simultaneously driving the brushes 6 on the two sleeves 5 to rotate inward, thereby achieving the rolling brushing of both sides of the polyester-cotton fabric, thereby cleaning the dust or other impurities on the polyester-cotton fabric.

[0026] When the roller brush mechanism needs to be cleaned or replaced during use, the operator only needs to remove the sealing plate 12 to open the inspection port 11, then use a tool to lock the end of the shaft 3 near the gear 8, and then use the tool to rotate the locking nut 7 to apply rotational force, thereby unscrewing the locking nut 7. Then the sleeve 5 can be pulled out from the shaft 3, and at the same time, the sleeve 5 can be taken out from the pretreatment box 2 through the inspection port 11, thereby realizing the disassembly of the brush assembly, which facilitates the cleaning of the brush 6 on the sleeve 5 and the later replacement of the new brush 6, thus facilitating the later maintenance of the equipment.

[0027] It should be noted that a sealing strip is provided on the inner side of the sealing plate 12 to achieve a sealed connection between the sealing plate 12 and the pretreatment box 2.

[0028] refer to Figures 1 to 5 As shown, two inner spline sleeves 13 are rotatably connected to the sealing plate 12, and one end of each of the two shafts 3 is fixedly connected to an outer spline shaft 14. The outer spline shaft 14 is splinedly connected to the inner spline sleeve 13. This mechanism uses the outer spline shaft 14 and the inner spline sleeve 13 to support this end of the shaft 3, thereby ensuring the stable operation of the shaft 3.

[0029] refer to Figures 1 to 5 As shown, the outer wall of the shaft 3 has an integrally formed protrusion 15, and the inner wall of the sleeve 5 has a strip groove 16. The protrusion 15 and the strip groove 16 are fitted and inserted. In this structure, the protrusion 15 and the strip groove 16 are used to ensure the power transmission between the shaft 3 and the sleeve 5, and to prevent the relative rotation between the sleeve 5 and the shaft 3.

[0030] refer to Figures 1 to 5 As shown, semi-circular guide grooves 17 are provided on both sides of the sealing plate 12, and guide posts 18 are fixedly installed on the outer wall of the pretreatment box 2 on both sides of the inspection port 11. The guide posts 18 are adapted to and snapped into the semi-circular guide grooves 17. This structure uses the guide posts 18 and the semi-circular guide grooves 17 to position the installation position of the sealing plate 12 and ensure that the outer spline shaft 14 and the inner spline sleeve 13 are adapted to and connected accordingly.

[0031] refer to Figures 1 to 5 As shown, suction hoods 19 are provided at the lower part of both shafts 3. The suction hoods 19 are fixedly installed on the inner wall of the pretreatment box 2. Both suction hoods 19 are fixedly connected to branch air pipes 20. A main air pipe 21 is fixedly connected to the branch air pipes 20. A filter box 22 is fixedly connected to the air outlet of the main air pipe 21. A fan 23 is fixedly connected to the lower part of the filter box 22. The fan 23 and the filter box 22 are both fixedly installed on the base frame 1. In this structure, the fan 23 generates suction, which sucks the dust and impurities that fall off the polyester-cotton fabric into the suction hoods 19. Then, the dust and impurities are sent into the filter box 22 through the branch air pipes 20 and the main air pipe 21. The filter box 22 intercepts and collects the dust and impurities that fall off the polyester-cotton fabric.

[0032] refer to Figures 1 to 5 As shown, the filter box 22 includes a barrel 24, with a barrel lid 25 connected to the top of the barrel 24 by a sealing thread. A support ring 26 is fixedly connected to the inner wall of the barrel 24, and multiple magnets 34 are fixedly connected to the support ring 26. An iron ring 27 is magnetically sealed to the support ring 26 by the magnets 34. A filter screen 28 is fixedly connected to the iron ring 27, and a lifting handle 29 is fixedly connected to the iron ring 27. In this structure, the filter screen 28 is used to intercept and collect dust and impurities that fall off the polyester-cotton fabric. When the filter screen 28 needs to be cleaned later, simply open the barrel lid 25 and then lift the filter screen 28 through the lifting handle 29, which makes it easy to clean the filter screen 28.

[0033] It should be noted that a sealing gasket is provided at the connection between the lid 25 and the body 24 to achieve a sealed connection between the lid 25 and the body 24. A sealing gasket is provided between the iron ring 27 and the support ring 26 to achieve a magnetic sealing connection between the support ring 26 and the iron ring 27.

[0034] refer to Figures 1 to 5 As shown, guide rollers 30 are provided in both the upper and lower parts of the inner cavity of the pretreatment box 2. This structure uses guide rollers 30 to guide and adjust the conveying direction of the polyester-cotton fabric.

[0035] refer to Figures 1 to 5 As shown, the pretreatment box 2 has an inlet 31 at the top and an outlet 32 ​​at the bottom. This structure allows the polyester-cotton fabric to enter the pretreatment box 2 easily through the inlet 31, and the processed polyester-cotton fabric to be transported out of the pretreatment box 2 easily through the outlet 32.

[0036] refer to Figures 1 to 5 As shown, a door 33 is hinged to one side of the pretreatment box 2. The door 33 is locked to the pretreatment box 2 sealing cover by a door lock. This structure allows the pretreatment box 2 to be opened by the door 33, which facilitates personnel to clean the inside and also facilitates the manual insertion of the polyester-cotton cloth into the pretreatment box 2 for the first time.

[0037] It should be noted that a sealing gasket is provided around the inner perimeter of the door 33 to connect the door 33 with the sealing cover of the processing box 22.

[0038] The implementation principle of a pre-treatment device for printing and dyeing polyester-cotton fabric according to an embodiment of this application is as follows: During use, the polyester-cotton fabric is guided by two guide rollers 30, so that it is conveyed from top to bottom. At this time, the drive motor 10 drives one of the shafts 3 to rotate, and the shaft 3 drives the other shaft 3 to rotate through the gear 8, thereby simultaneously driving the brushes 6 on the two sleeves 5 to rotate inward, thereby achieving the rolling brushing of both sides of the polyester-cotton fabric, thereby cleaning the dust or other impurities on the polyester-cotton fabric. At this time, the fan 23 generates suction, and then sucks the dust and impurities that fall off the polyester-cotton fabric into the suction hood 19. Then, the dust and impurities are sent into the filter box 22 through the branch air pipe 20 and the main air pipe 21, and the filter box 22 intercepts and collects the dust and impurities that fall off the polyester-cotton fabric.

[0039] When the roller brush mechanism needs to be cleaned or replaced during use, the operator only needs to remove the sealing plate 12 to open the inspection port 11, then use a tool to lock the end of the shaft 3 near the gear 8, and then use the tool to rotate the locking nut 7 to apply rotational force, thereby unscrewing the locking nut 7. Then the sleeve 5 can be pulled out from the shaft 3, and at the same time, the sleeve 5 can be taken out from the pretreatment box 2 through the inspection port 11, thereby realizing the disassembly of the brush assembly, which facilitates the cleaning of the brush 6 on the sleeve 5 and the later replacement of the new brush 6, thus facilitating the later maintenance of the equipment.

[0040] It should be noted that the power for conveying the above-mentioned polyester-cotton fabric is provided by an external winding device, which are all power sources well known in the art. Furthermore, this application does not make any improvements to the power source, so it will not be described in detail here.

[0041] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
