Abstract
Description
Technical Field
[0001] The present application relates to the technical field of brush roller clamping device design, and in particular to a brush roller clamping device. Background Art
[0002] Industrial brushes are used in almost all industries, and their main uses are cleaning, dust removal, polishing, etc. in industrial production processes. According to the manufacturing process, they can basically be divided into five categories: planting brushes, strip brushes, spring brushes, twist brushes, injection brushes, etc. According to the use category, they can be divided into brush rollers, drum brushes, brush wheels, disc brushes, strip brushes, plate brushes, special-shaped brushes, etc. According to the brush wire material, they can be divided into nylon brushes, steel wire brushes, copper wire brushes, plastic brushes, horsehair brushes, pig bristle brushes, wool brushes, sisal brushes, abrasive brushes, cotton brushes, etc.
[0003] The brush roller is composed of bristles and a roller. After the bristles are adhered to the curved surface of the roller to make a semi-finished brush roller, the connecting surface of the bristles needs to be pressed against the curved surface of the roller to prevent the bristles from falling off the roller. The common method of pressing the bristles is to roll the semi-finished brush roller on a plane. The disadvantage of this pressing method is that during the rolling of the semi-finished brush roller, since the brush roller and the plane are always in line contact, the reaction force of the plane on the brush roller can easily cause the bristles to slide from the squeezed position to both sides along the curved surface of the roller, causing the bristles to slip off the roller.

[0032] Reference Figure 1-6 ,
[0033] A brush roller pressing device includes: a bracket 1, a first clamping member 2 and a second clamping member 3. The bracket 1 forms an abutting surface 4 facing upward, and the abutting surface 4 is a circular plane, which is used to abut against the lower end surface of the brush roller to support the brush roller. The second clamping member 3 forms a plurality of second contact surfaces 6 that can be connected and separated from each other, specifically three second contact surfaces 6. When the three second contact surfaces 6 are close to each other, the three second contact surfaces 6 first clamp the lower end of the brush roller for preliminary positioning. The first clamping member 2 forms a plurality of first contact surfaces 5 that can be connected and separated from each other, specifically three first contact surfaces 5. When the three first contact surfaces 5 are connected to each other, the projections of the three first contact surfaces 5 on the abutting surface 4 coincide with the contour of the abutting surface 4. At this time, the three first contact surfaces 5 press the upper, middle and lower parts of the brush roller, so that the bristles are pressed against the roller.
[0034] Specifically, a plurality of first guide grooves 7 are formed on the bracket 1, specifically three first guide grooves 7, and the three first guide grooves 7 are radially distributed with the center of the abutting surface 4 as the center. The first clamping member 2 includes a plurality of first clamping blocks 8, specifically three first clamping blocks 8, and the first contact surface 5 is formed on the first clamping blocks 8. The first clamping blocks 8 are slidably connected with the first guide grooves 7 in a one-to-one correspondence. The three first clamping blocks 8 are pressed toward the center of the abutting surface 4 along the first guide grooves 7 from three directions, and the pressure on the brush roller located on the abutting surface 4 is uniform.
[0035] Specifically, a plurality of second guide grooves 9 are formed on the bracket 1, specifically three second guide grooves 9, and the three second guide grooves 9 are radially distributed with the center of the abutting surface 4 as the center of the circle. The second clamping member 3 includes a plurality of second clamping blocks 10, specifically three second clamping blocks 10, and a second contact surface 6 is formed on the second clamping block 10. The second clamping blocks 10 are slidably connected with the second guide grooves 9 in a one-to-one correspondence. The three second clamping blocks 10 are pressed toward the center of the abutting surface 4 along the second guide grooves 9 from three directions, forming a three-point positioning for the brush roller located on the abutting surface 4, so that the brush roller is located in the center of the abutting surface 4, which is convenient for the first clamping member 2 to press the brush roller.
[0036] Specifically, the first guide groove 7 and the second guide groove 9 are distributed at intervals, so that the three first clamping members 2 and the three second clamping members 3 can squeeze the brush roller from six directions, so that the brush roller is evenly stressed and is not easily deviated and fallen off from the bracket 1.
[0037] Specifically, a limit strip 11 is provided at the upper end of the first contact surface 5, and the limit strip 11 is glued and fixed to the first clamping block 8. When all the first contact surfaces 5 are connected to each other, the limit strip 11 is formed into a ring to abut against the upper end of the brush roller to prevent the brush roller from slipping out of the upper end of the first clamping block 8.
[0038] Specifically, the first clamping member 2 also includes a plurality of first cylinders 12 and a plurality of first push blocks 13, specifically three first cylinders 12 and three first push blocks 13, and the three first cylinders 12 and the three first push blocks 13 correspond to each other. The outer shell of the first cylinder 12 is fixed to the bracket 1 by bolts, the output end of the first cylinder 12 is fixed to the first push block 13 by bolts, and the first push block 13 is fixed to the first clamping block 8 by bolts. The first cylinder 12 makes the first clamping block 8 slide back and forth along the first guide groove 7 through the first push block 13. When the first cylinder 12 pushes the first push block 13 toward the center of the abutment surface 4, the first clamping blocks 8 approach each other and connect. When the first cylinder 12 pulls the first push block 13 back, the first clamping blocks 8 move away from each other. The fixed ends of all the first cylinders 12 are connected in series to the external air source to improve the operation synchronization of the three first cylinders 12 and enhance the uniform squeezing effect of the first clamping block 8 on the brush roller.
[0039] Specifically, the second clamping member 3 also includes a plurality of second cylinders 14 and a plurality of second push blocks 15, specifically three second cylinders 14 and three second push blocks 15, the three second cylinders 14 and the three second push blocks 15 correspond one to one, the outer shell of the second cylinder 14 is fixed to the bracket 1 by bolts, the output end of the second cylinder 14 is fixed to the second push block 15 by bolts, and the second push block 15 is fixed to the second clamping block 10 by bolts. The second cylinder 14 causes the second clamping block 10 to slide back and forth along the second guide groove 9 through the second push block 15. When the second cylinder 14 pushes the second push block 15 toward the center of the abutting surface 4, the second clamping blocks 10 approach each other, and when the second cylinder 14 pulls the second push block 15 back, the second clamping blocks 10 move away from each other. The fixed ends of all the second cylinders 14 are connected in series to the external air source to improve the operation synchronization of the three second cylinders 14 and enhance the accuracy of the second clamping block 10 positioning the lower end of the brush roller.
[0040] Specifically, the bracket 1 forms a first guide rail 16, a first slider 17 is disposed below the first push block 13, the first push block 13 and the first slider 17 are detachably connected by bolts, and the first slider 17 is slidably connected to the first guide rail 16. The bracket 1 forms a second guide rail 18, a second slider 19 is disposed below the second push block 15, the second push block 15 and the second slider 19 are detachably connected by bolts, and the second slider 19 is slidably connected to the second guide rail 18. Since the first slider 17 and the first guide rail 16 will wear when they rub against each other, and the second slider 19 and the second guide rail 18 will wear when they rub against each other, the detachable connection between the first push block 13 and the first slider 17 facilitates the replacement of the first slider 17, and the detachable connection between the second push block 15 and the second slider 19 facilitates the replacement of the second slider 19.
