Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0024] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] For example, Figures 1 to 5As shown, an automatic sanding device includes a horizontally arranged feeding device 1 and a sanding device 2 arranged at the top of the feeding device 1, the feeding device 1 includes a circulating conveyor belt and a support frame supporting the conveyor belt, the sanding device 2 includes two sanding rollers 21 rotatably arranged above the conveyor, the two ends of the sanding roller 21 are respectively arranged at the top of the support frame through a mounting seat 22, the two ends of the sanding roller 21 are respectively slidably arranged on the mounting seat 22 through a first slider 23, and the top of the mounting seat 22 is provided with an adjusting motor 24 drivingly connected to the first slider 23.

[0026] In this technical solution, the support frame is spliced ​​by conventional profiles and plates, and is used for the setting of the conveyor belt. The two ends of the transmission belt are respectively set on the support frame through conventional rollers, and one of the rollers is connected to the circulating motor through a belt or a synchronous belt or a chain. The specific structure and principle belong to the prior art and will not be elaborated here. The cloth is conveyed by the conveyor belt and passes under the sanding device. The sanding roller is rotated by an external conventional driving motor. The sanding roller of the sanding device sands the cloth. According to the thickness of the cloth, the motor is adjusted to drive the first slider to slide along the mounting seat, thereby adjusting the distance between the sanding roller and the conveyor belt to meet the sanding requirements of cloth of different thicknesses.

[0027] For example, Figure 1 As shown, the support frame includes a support cabinet and two longitudinal beams parallel to the top of the support cabinet, the conveyor belt is rotatably arranged between the two longitudinal beams, and a nut groove is arranged at the top of the longitudinal beam.

[0028] In this technical solution, the longitudinal beam is made of existing aluminum profiles, and a nut groove is formed on the top to facilitate the use of post-nuts and the installation of mounting seats, etc. The rollers of the conveyor belt are vertically arranged between the two longitudinal beams, that is, the conveyor belt is cyclically rotated between the two longitudinal beams, and the circulating motor is fixed to the corresponding longitudinal beam by a motor seat, etc. The supporting cabinet is made of existing metal cabinets or is spliced ​​by plates and profiles. The conveyor belt is set to a certain horizontal height to facilitate fabric loading, etc. In order to prevent the fabric from deviating outside the conveyor belt, limit strips are respectively arranged on the top of the longitudinal beams. The limit strips can be made of existing angle irons, and through grooves are processed at the locations of the mounting seats, etc. to expose the nut grooves of the longitudinal beams to avoid interference with the use of post-nuts.

[0029] For example, Figures 1 to 3 As shown, the mounting seat 22 is fixed to the top end of the corresponding longitudinal beam, and is provided with a mounting groove with an open top end, and the first sliding block 23 is slidably disposed in the mounting groove.

[0030] In this technical solution, the two side surfaces of the first slider slide on the corresponding side walls of the mounting groove through conventional structures such as linear guides (not shown) or dovetail structures, and the distance between the corresponding grinding roller and the conveyor belt is adjusted by the first slider. The rotating shaft of the grinding roller is rotatably connected to the first slider through conventional structures such as bearings. One end of the rotating shaft of the grinding roller protrudes from the corresponding first slider and is connected to the driving motor through a belt or a synchronous belt or a chain. The driving motor (not shown) uses an existing motor and is fixed to the support frame through a conventional motor seat. The two grinding rollers are respectively connected to different driving motors, that is, the two grinding rollers rotate at different or the same speeds, and the secondary grinding is completed at the same time, thereby improving the processing efficiency.

[0031] For example, Figures 1 to 3 As shown, a mounting block 25 is provided at the top of the mounting seat 22 , and the adjusting motor 24 is fixed to the mounting block 25 through a motor bracket 26 . The output end of the adjusting motor 24 is connected to the first slider 23 through a driving shaft 27 , and the driving shaft 27 passes through the mounting block 25 .

[0032] In this technical solution, the adjusting motor can be an existing synchronous motor. The adjusting motor is suspended above the mounting seat through a mounting block and a motor bracket, and the output end of the adjusting motor is connected to a driving shaft. The driving shaft passes through the mounting block and is connected to the first slider. The adjusting motor drives the first slider to slide through the driving shaft, thereby adjusting the installation height of the grinding roller. The driving shaft includes a connecting head connected to the output shaft of the adjusting motor and a screw connected to the connecting head. The screw and the connecting head are axially connected by a conventional hinge structure or a floating connection structure. The specific structure and principle belong to the prior art and will not be elaborated here.

[0033] For example, Figures 1 to 3 As shown, a second slider 28 is disposed at the top of the first slider 23 , a connecting sleeve 29 is disposed between the first slider 23 and the second slider 28 , and the driving shaft 27 is connected to the connecting sleeve 29 via a threaded structure.

[0034] In this technical solution, the second slider is fixed to the top of the first slider by screws, etc. The connecting sleeve is a copper T-shaped structure, including a base and a connecting tube arranged perpendicular to the base. The connecting tube is embedded in the second slider and fixed by interference fit or top screws. A threaded through hole is arranged in the center of the connecting tube. The base is fixed to the bottom surface of the second slider, and the screw of the driving shaft is connected to the threaded through hole. When the adjusting motor drives the driving shaft to rotate, the first slider and the second slider are driven to slide through the threaded structure between the screw and the connecting sleeve, thereby adjusting the installation height of the grinding roller.

[0035] For example, Figures 1 to 3As shown, the top surface of the first slider 23 is provided with a first avoidance groove corresponding to the drive shaft 27, the bottom surface of the second slider 28 is provided with a second avoidance groove corresponding to the connecting sleeve 29, and the bottom surface of the mounting block 25 is provided with a third avoidance groove corresponding to the second slider 28.

[0036] In this technical solution, the first avoidance groove and the second avoidance groove enable the bottom of the drive shaft to protrude from the bottom of the connecting sleeve to avoid interfering with the sliding of the first slider. The width of the third avoidance groove is greater than the width of the second slider to avoid interfering with the sliding of the second slider. The width of the third avoidance groove is less than the width of the first slider to limit the sliding stroke of the first slider and avoid interference from the grinding roller and dust hood.

[0037] For example, Figure 1 and Figure 4 As shown, the grinding device 2 is provided with pressing rollers 3 on both sides along the travel direction of the conveyor belt, and both ends of the pressing rollers 3 are connected to the top of the support frame through adjustment seats 31.

[0038] In this technical solution, the pressing roller can be an existing rubber-coated roller, which fixes the cloth on the surface of the conveyor belt to avoid uneven grinding caused by wrinkles.

[0039] For example, Figure 2 As shown, the two ends of the pressing roller 3 are slidably arranged in the adjustment seat 31 through the third slider 32 respectively, and a sliding groove corresponding to the third slider 32 is arranged in the adjustment seat 31. An adjusting bolt 33 connected to the third slider 32 is arranged at the top of the adjustment seat 31, and a compression spring 34 is arranged between the third slider 32 and the top of the sliding groove, and is sleeved on the adjusting bolt 33.

[0040] In this technical solution, the third slider is fixed to the two ends of the pressing roller shaft by welding or other means, so that the two ends of the pressing roller are connected to the corresponding adjustment seats, and mounting bosses are respectively protruded from the bottom ends of both sides of the adjustment seat, and a U-shaped groove is machined in the mounting bosses, which are installed on the longitudinal beam of the support frame with screws and post-mounted nuts. Pressure is applied to the third slider by means of a compression spring, so that the pressing roller applies elastic pressure to the cloth, so that the cloth always fits the surface of the conveyor belt, and the height of the third slider can be adjusted by rotating the adjusting bolt to meet the processing requirements of cloth of different thicknesses.

[0041] For example, Figure 1 and Figure 5 As shown, a dust collecting device 4 is provided at the top of the sanding device 2. The dust collecting device 4 includes a dust collecting hood 42 provided at the top of the sanding device 2 through a mounting plate 41. A connecting pipe 43 penetrating the mounting plate is provided at the top of the dust collecting hood 42 and connected to a vacuum cleaner (not shown).

[0042] In this technical solution, the vacuum cleaner is placed in a supporting cabinet and connected to a connecting pipe through a hose, etc. The hose runs through the corresponding side wall of the supporting cabinet. Bending plates are respectively arranged on both sides of the mounting plate to improve the strength of the mounting plate. The mounting plate is fixed to the top of the motor bracket by screws. The top of the dust hood is fixed to the bending plate on the side of the mounting plate by angle irons and screws. The dust hood is a gradually closing pyramid structure, and the hair generated by sanding and adhered to the sanding roller is collected by the vacuum cleaner.

[0043] For example, Figure 1 As shown, a plurality of ventilation holes are arranged in the conveyor belt.

[0044] In this technical solution, in order to improve the safety of use, conventional safety covers are arranged on the top and sides of the support frame to encapsulate the sanding device and the driving motor, and the covers are installed on both sides of the conveyor belt along the travel direction and at intervals between the conveyor belts to avoid interference with the cloth transmission. When the vacuum cleaner collects hair through the dust collecting device, air flows upward through the ventilation holes in the conveyor belt and circulates with the air flow during the vacuum cleaner stroke to improve the dust collection effect. A guide plate is hinged at one end of the support frame close to the conveyor belt discharge to send the sanded cloth into a collection tray and other devices.

[0045] In summary, the automatic sanding device has a simple structure, and the distance between the sanding roller and the conveyor belt can be adjusted according to the actual needs of the product to improve the sanding effect and expand the scope of application; pressing rollers are respectively provided at both ends of the sanding device to ensure the flatness of the fabric and improve the sanding effect; the dust collection device collects the fluff generated during the sanding process to improve the working environment and the sanding effect.

[0046] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0047] The above is only a specific implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
