Description

Technical Field

[0001] The utility model relates to the technical field of tile pressing machines, in particular to a C-shaped tile pressing machine roller which is easy to disassemble and assemble. Background Art

[0002] C-type plate tile pressing machine is a device that cold presses steel plates into concave and convex tile-shaped structures. Its main components are multiple sets of rotatable rollers, each set of rollers is divided into two, upper and lower. When the steel plate passes between the upper and lower rollers, it can be pressed by the rollers into the desired shape.

[0003] At present, a group of corresponding rollers in a C-type tile press are usually mounted between two brackets during installation. After the rollers are installed, the distance between the brackets is also locked. At this time, when it is necessary to dismantle and repair or replace one of the faulty rollers in the group, it is necessary to first dismantle the entire group of rollers as a whole and release the spacing lock of the brackets. This operation is very inconvenient, and there is a problem that the rollers are difficult to disassemble and use independently.

[0004] Therefore, we propose a C-type tile press roller that is easy to disassemble and assemble to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a C-type plate tile press roller which is easy to disassemble and assemble, so as to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A C-type plate tile press roller that is easy to disassemble and assemble, includes a rotating rod and a plurality of rolling wheels distributed along the axial direction of the rotating rod, end shafts are fixed at both ends of the rotating rod, and a connecting shaft is slidably sleeved on the outer side of each end shaft, a central gear is rotatably installed on the inner center of the rotating rod, and a pair of racks are meshed and connected to the outer edge of the central gear, the pair of racks are symmetrical about the center of the circle of the central gear, and one end of the rack passes through the end of the rotating rod and is fixed to the connecting shaft, and when the central gear rotates, the connecting shaft is controlled to telescopically move relative to the end shaft through the rack.

[0008] In a further embodiment, a core rod is fixed at the axis of the central gear, one end of the core rod is rotatably connected to the inner wall of the rotating rod, and the other end of the core rod passes through the outer wall of the rotating rod and is threadedly sleeved with a nut.

[0009] In a further embodiment, a groove is provided on the outer side surface of the rack, and a convex strip matching the groove is provided on the inner wall of the rotating rod, and the rack is slidably connected to the rotating rod via the groove and the convex strip.

[0010] In a further embodiment, a flexible anti-slip layer is installed on the outer side wall of the connecting shaft.

[0011] In a further embodiment, the flexible anti-slip layer passes through the inner and outer side walls of the connecting shaft, and a sliding rod is fixed inside the connecting shaft, the end of the sliding rod away from the end shaft is slidably sleeved with a sliding table, and the other end of the sliding rod is hinged with an extrusion strip, a connecting rod is hinged between the extrusion strip and the sliding table, and a movable block is connected to the sliding table, which passes through the outer surface of the connecting shaft.

[0012] In a further embodiment, the extrusion strip corresponds to the flexible anti-skid layer one by one, and when the movable block retracts into the connecting shaft, the slide controls the extrusion strip to expand through the connecting rod to extrude the flexible anti-skid layer protruding from the outer surface of the extrusion strip.

[0013] In a further embodiment, one end of the slide away from the movable block is connected to a spring, and the slide rod passes through the interior of the spring.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The utility model rotates the central gear and relies on the meshing action between the central gear and the rack to synchronously drive the connecting shafts at both ends of the rotating rod to move telescopically relative to the end shafts, so as to adjust the installation length of the entire rolling roller. When the bracket spacing of the tile press is locked, the length of the rolling roller can be shortened to enable it to be removed from the bracket, and the length of the rolling roller can be increased to enable it to be installed on the bracket. There is no need to dismantle the entire group of rolling rollers as a whole, so that each roller can be independently loaded and unloaded for use, and the operation is more convenient.

[0024] See also Figure 1-2 The invention discloses a C-type plate tile press roller which is easy to disassemble and assemble, comprising a rotating rod 1 and a plurality of rolling wheels 2 distributed along the axial direction of the rotating rod 1, wherein the rolling wheels 2 are fixed to the rotating rod 1 so as to rotate with the rotating rod 1, and end shafts 3 are fixed to both ends of the rotating rod 1, and the end shafts 3 are connected to the rotating rod 1 by bolts, so as to expose the internal structure of the rotating rod 1 after disassembly, and a connecting shaft 4 is slidably sleeved on the outer side of each end shaft 3, and the connecting shaft 4 slides to the side away from the rotating rod 1, thereby increasing the length of the entire rolling roller, so that it can be mounted between two brackets, and vice versa, the length of the rolling roller is shortened, so as to facilitate its disassembly from the bracket, and a central gear 5 is installed for rotation at the inner center of the rotating rod 1, and a pair of racks 6 are meshed and connected to the outer edge of the central gear 5, and the pair of racks 6 are symmetrical about the center of the circle of the central gear 5, and one end of the rack 6 passes through the end of the rotating rod 1 and is fixed to the connecting shaft 4, so that when the central gear 5 rotates, the connecting shafts 4 on both sides are synchronously controlled to telescopically move relative to the end shafts 3 through meshing with the rack 6, so that it is easy to disassemble and assemble.

[0025] See also Figure 1-3 In order to facilitate the control of the rotation of the central gear 5, a core rod 7 is fixed at the axis of the central gear 5. One end of the core rod 7 is rotatably connected to the inner wall of the rotating rod 1, and the other end of the core rod 7 passes through the outer wall of the rotating rod 1, so that the user can rotate the core rod 7 from the outside of the rotating rod 1 to drive the central gear 5 to rotate. The outer surface of one end of the core rod 7 extending out of the outer wall of the rotating rod 1 is provided with a thread, which is screwed to the outside of the rotating rod 1 through a nut 8. When the nut 8 is locked, the core rod 7 can be locked so that it cannot rotate, thereby fixing the length of the roller.

[0026] See also Figure 3 In order to improve the stability of the rack 6 when it moves, a groove 61 is provided on the outer surface of the rack 6, and a convex strip 11 matching the groove 61 is provided on the inner wall of the rotating rod 1. The rack 6 is slidably connected to the rotating rod 1 through the groove 61 and the convex strip 11, so that the convex strip 11 can support and limit the rack 6, thereby reducing the bending and deviation of the rack 6.

[0027] See also Figure 4 , considering that in order to facilitate the insertion of the connecting shaft 4 into the connecting seat of the bracket, the outer diameter of the connecting shaft 4 should be set smaller than the inner diameter of the connecting seat, and at this time there is a gap between the two after the connection, which affects the stability of the roller when rotating. In order to improve the connection stability of the roller after installation, a flexible anti-skid layer 41 is installed on the outer wall of the connecting shaft 4. The flexible anti-skid layer 41 can be made of elastic silicone or elastic rubber material. The flexible anti-skid layer 41 runs through the inner and outer walls of the connecting shaft 4, and a sliding rod 42 is fixed inside the connecting shaft 4. The end of the sliding rod 42 away from the end shaft 3 is slidably sleeved with a sliding table 43, and the other end of the sliding rod 42 is hinged with an extrusion strip 44, the extrusion strip 44 corresponds to the flexible anti-skid layer 41 one by one, a connecting rod 45 is hinged between the extrusion strip 44 and the sliding table 43, and a movable block 46 is connected to the side of the sliding table 43 away from the extrusion strip 44, and the movable block 46 runs through the outer surface of the connecting shaft 4, and is set when the connecting shaft 4 is inserted into the bracket. When the movable block 46 is in the connecting seat, the movable block 46 can be gradually squeezed. When the movable block 46 retracts into the interior of the connecting shaft 4, the slide 43 is driven to move along the slide rod 42, and the squeezing strip 44 is controlled to expand by the connecting rod 45. The squeezing strip 44 squeezes the flexible anti-skid layer 41, so that it protrudes from the outer surface of the squeezing strip 44, thereby filling the gap, which is beneficial to improve the stability of the connecting shaft 4 after installation. In order to facilitate the disassembly of the connecting shaft 4, a spring 47 is connected to the end of the slide 43 away from the movable block 46, and the slide rod 42 runs through the inside of the spring 47. That is to say, when the movable block 46 drives the slide 43 to retract, the spring 47 will be squeezed to shorten. When disassembling, the connecting shaft 4 gradually moves away from the connecting seat. At this time, the slide 43 can be driven to move back and reset under the elastic force of the spring 47, so that the squeezing strip 44 is retracted and no longer squeezes the flexible anti-skid layer 41. The flexible anti-skid layer 41 is reset, thereby reducing the resistance formed by the flexible anti-skid layer 41 when the connecting shaft 4 is withdrawn.
