Description

Technical Field

[0001] The invention belongs to the technical field of brush rollers, and in particular relates to a brush roller structure which is convenient for replacing brush strips. Background Art

[0002] Due to the iron nature of steel itself, oxide scale or rust will appear on its surface. Therefore, before further processing, it is generally necessary to use a brush roller covered with brush strips to polish the steel surface to remove the oxide scale or rust on the surface of the steel plate and make it shiny and smooth.

[0003] In the prior art, most brush strips are directly fixed to the circumference of the brush roller. When part of the brush strip is worn out, the entire brush roller needs to be replaced. This not only increases the cost of use, but also wastes materials and is inconvenient to use. At the same time, the process of replacing the brush roller is time-consuming, thus affecting the working efficiency of the rust remover. Therefore, it is urgent to develop a brush roller structure that is easy to replace the brush strips in order to solve the above problems. Summary of the Invention

Specific embodiments

[0033] Based on the specific embodiment 1, Figure 2-Figure 3 and Figure 5-Figure 6As shown, both opposite ends of the accommodating chamber 102 are provided with limiting grooves 103; the limiting groove 103 is provided at an edge of the accommodating chamber 102 close to the central axis of the roller body 1; the locking assembly 5 includes a pair of bearing blocks 501 respectively provided in the two opposite ends of the accommodating chamber 102 and a pair of movable shafts 502 inserted side by side in the accommodating chamber 102; one edge of the bearing block 501 is slidably inserted into the limiting groove 103; a surface of the bearing block 501 close to the accommodating chamber 102 is provided with a pair of sliding grooves 5011 corresponding to the movable shafts 502; the sliding grooves 5011 are provided in parallel with the pull rod 4; the two movable shafts 502 are provided on opposite sides of the pull rod 4; the movable shaft 5 02 is arranged between the positioning rod 401 and the installation groove 101; the two ends of the movable shaft 502 are respectively movably inserted into the sliding groove 5011 on the two bearing blocks 501 and are threadedly matched with a locking sleeve 503; the movable shaft 502 can slide along the length direction of the sliding groove 5011, and can also slide in the sliding groove 5011 along the length direction of the support bar 2; a plurality of locking cams 504 corresponding to the positioning rod 401 are fixedly sleeved on the movable shaft 502; the outer contour of the locking cam 504 conflicts with a surface of the positioning rod 401 close to the support bar 2; the outer contour of the locking cam 504 has a flat surface; the flat surface is arranged at the maximum radius of the locking cam 504. When in use, when it is necessary to position the brush strip 3, after all the pull rods 4 on the support bar 2 are moved into the installation groove 101, the two ends of the movable shaft 502 are movably inserted into the slide grooves 5011 on the two bearing blocks 501, and then the movable shaft 502 is rotated to drive the locking cam 504 to move in the accommodating chamber 102, so that the outer contour of the locking cam 504 conflicts with a surface of the positioning rod 401 close to the support bar 2, and at the same time, the movable shaft 502 moves in the slide groove 5011. When the movable shaft 502 moves to the end of the slide groove 5011 away from the central axis of the roller body 1, the locking cam 504 is moved. 04's maximum radius point conflicts with a surface of the positioning rod 401 close to the support bar 2. At this time, the flat surface of the locking cam 504 conflicts with a surface of the positioning rod 401 close to the support bar 2, forming a surface-to-surface fit, so that the positioning rod 401 can be pressed tightly into the accommodating chamber 102. Then, by threading the locking sleeve 503 onto the end of the movable shaft 502 and tightening the locking sleeve 503 so that one end of the locking sleeve 503 conflicts with the outer surface of the bearing block 501, the bearing block 501 is firmly fitted into the limiting groove 103, thereby locking the position of the positioning rod 401 and further locking the position of the brush strip 3. In addition, Figure 10As shown, in order to further improve the locking effect of the positioning rod 401, pins 5013 corresponding to the slide groove 5011 are inserted into the two opposite side surfaces of the bearing block 501 along the length direction of the positioning rod 401, one end of the pin 5013 can be inserted into the slide groove 5011, and the pin 5013 is threadedly matched with the bearing block 501, and then a hole 5021 corresponding to the pin 5013 is axially opened at both ends of the positioning rod 401. When the movable shaft 502 moves to the end of the slide groove 5011 away from the central axis of the roller body 1, one end of the pin 5013 is first inserted into the positioning In the channel 5021 of the rod 401, the circumferential side walls of the pin 5013 are in contact with the two opposite side surfaces of the channel 5021, and the pin 5013 slides in cooperation with the channel 5021 (at this time, the other end of the pin 5013 is just flush with the side surface of the supporting block 501, and a straight groove is provided on the other end surface of the pin 5013, and a flat-blade screwdriver is used to cooperate with the straight groove to drive the pin 5013), thereby preventing the movable shaft 502 from rotating in the slide groove 5011, and then tightening the locking sleeve 503 to achieve dual positioning of the supporting block 501 and the movable shaft 502.

[0034] Among them Figure 6 and Figure 9 As shown, the other edge of the carrier block 501 is provided with a blocking protrusion 5012 corresponding to the mounting groove 101; the blocking protrusion 5012 slides within the mounting groove 101 and contacts the end surface of the support bar 2. By designing the blocking protrusion 5012 to slide within the mounting groove 101, the sealing of the receiving chamber 102 can be ensured.

[0035] Among them Figure 2-Figure 3 、 Figure 6 and Figure 8 As shown, a pair of connecting blocks 505 are rotatably mounted on the movable shaft 502. A tension spring 506 connects one surface of the connecting block 505 to a surface of the accommodating chamber 102. The tension spring 506 is disposed between the connecting block 505 and the support bar 2. By designing the connection between the connecting block 505 and a surface of the accommodating chamber 102 using the tension spring 506, the position of the movable shaft 502 can be effectively controlled. When the movable shaft 502 moves to the end of the chute 5011 away from the central axis of the roller body 1, the tension spring 506 exerts a tensile force on the movable shaft 502. Specific embodiments

[0036] Based on the specific embodiment 2, Figure 3 and Figure 5-Figure 8As shown, a plurality of through-holes 104 are formed side by side along the length of a surface of the accommodating chamber 102 near the support bar 2; a plurality of positioning holes 201 corresponding to the through-holes 104 are formed side by side on a surface of the support bar 2; a plurality of rotating sleeves 507 corresponding to the through-holes 104 are rotatably sleeved on the movable shaft 502; a protrusion 508 made of elastic rubber is radially fixed to the outer wall of the rotating sleeve 507; the protrusion 508 slides through the through-hole 104; one end of the protrusion 508 can be inserted into the corresponding positioning hole 201; when one end of the protrusion 508 is inserted into the corresponding positioning hole 201, the protrusion 508 and the positioning hole 201 have an interference fit. When the movable shaft 502 moves to the end of the slide groove 5011 away from the central axis of the roller body 1, one end of the protrusion 508 moves from the through-hole 104 to the positioning hole 201, at which point the protrusion 508 and the positioning hole 201 have an interference fit, thereby further defining the position of the support bar 2.

[0037] Among them Figure 6 and Figure 8 As shown, the two movable shafts 502 are connected at the same end by a blocking piece 509 for blocking the slide groove 5011. The blocking piece 509 is loosely fitted with the movable shaft 502 and is disposed between the bearing block 501 and the locking sleeve 503. By designing the blocking piece 509 to block the slide groove 5011, the sealing of the accommodating chamber 102 can be ensured.
