Description

Technical Field

[0001] The present invention belongs to the technical field of rubber roller forming, and specifically relates to a high-precision rubber roller forming machine and its automatic centering device. Background Art

[0002] A rubber roller is a composite roller structure formed by vulcanizing a rubber-like material coating on a roll core made of metal or other hard materials. It has a wide range of applications and can be used in papermaking, printing, rice hulling, metallurgy, mimeographing and other fields. Rubber roller forming mainly involves pasting rubber on a metal core, and there are methods such as the wrapping method, extrusion method, molding method, injection molding method and injection method. At present, in China, it is mainly manual or mechanical pasting for forming, while in foreign countries, most have achieved mechanical automation. Large and medium-sized rubber rollers basically use profiling extrusion, and are produced by the method of continuously pasting extruded rubber sheets or continuously winding extruded rubber strips. During the forming process, the specifications and appearance shapes are automatically controlled by a microcomputer, and in some cases, the forming can also be carried out by the method of right-angle and special-shaped extrusion using an extruder.

[0003] A patent with the publication number of CN112497607A discloses a rubber roller thermoplastic forming machine. On the workbench frame, there are a first support end plate, a second support end plate and a heating light roller. The first support end plate is provided with a first rubber roller assembly hole and a first heating roller assembly hole. There are at least three first heating roller assembly holes, which are arranged at equal intervals along the circumferential direction of the first rubber roller assembly hole on the outer periphery of the first rubber roller assembly hole. The second support end plate is provided with a second rubber roller assembly hole for assembling the rubber roller to be heated and shaped and a second heating roller assembly hole for assembling the heating light roller. The rubber roller, the first rubber roller assembly hole and the second rubber roller assembly hole are arranged in one-to-one correspondence, and the heating light roller, the first heating roller assembly hole and the second heating roller assembly hole are arranged in one-to-one correspondence; the output end of the power output device is connected to the power input end of at least one heating light roller to drive the heating light roller to rotate.

[0004] In the current prior art, when the existing high-precision rollers are injection-molded, due to the difference in injection extrusion pressure, the adhesion between the rubber and the roller is different, and there will be a certain gap between them. Moreover, during injection molding, when the rubber is extruded, the initial rubber will solidify first, which will block the subsequent extrusion, resulting in an uneven surface of the rubber. When trimming, manual trimming cannot keep the thickness of the rubber layer consistent.

[0005] Therefore, the present invention provides a high-precision rubber roller forming machine and its automatic centering device. Summary of the Invention

A transmission track is movably sleeved on the output end of the motor three, and the inner wall surface of the transmission track is movably sleeved on the outer surface of the transmission gear tooth.

[0008] Preferably, are fixedly installed on both side surfaces of the rubber roll forming table and located at the edge positions on both sides of the limiting grooves. A motor two is fixedly installed on the top surface of the support plate, and a threaded rod is fixedly connected to the output end of the motor two.

[0009] Preferably, a slider is threadedly movably sleeved on the outer surface of the threaded rod. A limiting disk is fixedly connected to one end of the slider. The outer surface of the limiting disk is movably lapped on the inner wall surface of the limiting groove. An extrusion roller is fixedly connected to the other side surface of the limiting disk.

[0010] Preferably, arc-shaped lapping plates are fixedly connected to the inner wall surfaces on both sides of the rubber roll forming table, and the positions of the arc-shaped lapping plates are set at the bottom edge positions of the high-precision rubber roll. Infrared heating rods are fixedly installed on the inner wall surfaces on both sides of the rubber roll forming table, and the positions of the infrared heating rods are set at the bottom edge positions of the arc-shaped lapping plates.

[0011] Preferably, a slotted opening is provided on the top surface of the arc-shaped lapping plate. A closing cover is swingably connected to the top surface of the rubber roll forming table. Circulation blowers are fixedly installed on both side surfaces of the rubber roll forming table and located at the bottom edge positions.

[0012] Preferably, a support rod is fixedly connected to one side surface of the limiting rod two, and a rubber roll lapping plate is provided at one end of the support rod.

[0013] Preferably, a first hydraulic rod is fixedly installed on the inner side wall surface of the rubber roller lapping plate, and the output end of the first hydraulic rod is fixedly connected with a semi-circular closed cover that is movably lapped on the top surface of the rubber roller lapping plate.

[0014] In a second aspect, there is a high-precision rubber roller automatic centering device. Two groups of second hydraulic rods are fixedly installed on the outer surface of the second limiting rod. The positions of the second hydraulic rods are at the two side edges of the support rod. The output ends of the second hydraulic rods are fixedly connected with lapping centering discs that are movably sleeved on the outer surface of the rubber roller lapping plate.

[0015] Preferably, the outer surface of the rubber roller lapping plate is movably lapped on the outer surface of the rubber layer. A rectangular clamping column is fixedly connected to the inner side wall surface of the semi-circular closed cover. Rectangular docking grooves are formed on the two end surfaces of the high-precision rubber roller. The outer surface of the rectangular clamping column is movably sleeved on the inner side wall surface of the rectangular docking groove.

[0016] The beneficial effects of the present invention are as follows: 1. For the high-precision rubber roller forming machine and its automatic centering device of the present invention, after the surface of the rubber layer is extruded and formed, the motor three twists the transmission track to drive the transmission gear teeth and the second limiting rod to rotate, so that the high-precision rubber roller rotates rapidly on the inner side wall surface of the rubber roller forming table. At this time, the motor one rotates the lead screw, and the high-precision grinding knife on the surface of the lead screw moves slowly under the limitation of the first limiting rod. When one end of the high-precision grinding knife slides from one side to the other side on the surface of the rubber layer, the surface of the high-precision grinding knife will cut and trim the excess rubber layer and some protruding rubber layers on the surface of the rubber layer. The cut rubber layer will fall into the interior of the rubber roller forming table under the action of gravity for recycling. 2. For the high-precision rubber roller forming machine and its automatic centering device of the present invention, when the high-precision rubber roller is clamped into the interior of the rubber roller forming table, the infrared heating rod is used to heat the bottom surface of the rubber layer at a high temperature. The heat source after heating is transmitted upward through the slotted opening, and the heat source contacts the surface of the rubber layer, thereby softening the surface of the rubber layer. At this time, the motor two rotates the threaded rod and drives the slider and the limiting disc on the outer surface of the threaded rod to move together towards the rubber layer. When the extrusion roller contacts the surface of the rubber layer, the rotation of the rubber layer and the extrusion of the extrusion roller will plastically process the surface of the rubber layer. 3. In the high-precision rubber roll forming machine and its automatic centering device of the present invention, when the surface of the rubber layer is extruded and shaped by the extrusion roller, when the excess rubber layer transfers to both ends, the hydraulic rod II is used to push the lap centering plate, so that the lap centering plate is sleeved on the surface of the rubber layer. By using the blocking of the lap centering plate, the rubber layer is blocked when it deforms and extends. The blocked rubber layer is repeatedly compressed by the extrusion roller on the surface of the rubber layer, so that the rubber layer can be more evenly and tightly attached to the surface of the high-precision rubber roll, thereby reducing the gap between the rubber layer and the high-precision rubber roll and increasing the adhesion effect.

Detailed implementation mode

[0020] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation modes.

[0021] Embodiment 1 As Figures 1 to 11 shown, the high-precision rubber roller forming machine of the embodiment of the present invention includes a rubber roller forming table 11 and support plates 12 symmetrically and fixedly installed on both side surfaces of the rubber roller forming table 11, a motor 3 13 symmetrically and fixedly installed on the top surface of the rubber roller forming table 11 and located at both side edge positions, a high-precision rubber roller 14 movably sleeved on the inner wall surface of the rubber roller forming table 11, limit grooves 111 opened on both side surfaces of the rubber roller forming table 11 and located at both side edge positions, a motor 1 116 fixedly installed on the inner wall surface of the rubber roller forming table 11, a lead screw fixedly connected to the output end of the motor 1 116, and a limit rod 1 117 fixedly connected to the inner wall surface of the rubber roller forming table 11 and located at one side edge position of the lead screw. A high-precision grinding knife 118 is arranged on the surfaces of the limit rod 1 117 and the lead screw; A rubber layer 141 is arranged on the outer surface of the high-precision rubber roller 14, and the output end of the high-precision grinding knife 118 is movably overlapped on the outer surface of the rubber layer 141; Limit rods 132 are movably sleeved on both side surfaces of the rubber roller forming table 11 and located at the middle positions between the two groups of limit grooves 111. A drive gear 133 is fixedly connected to the outer surface of the limit rod 132. A drive track 131 is movably sleeved on the output end of the motor 3 13, and the inner wall surface of the drive track 131 is movably sleeved on the outer surface of the drive gear 133.

[0022] The rubber is extruded and adhered to the surface of the high-precision rubber roller 14, so that a rubber layer 141 is formed on the surface of the high-precision rubber roller 14. The high-precision rubber roller 14 is placed on the inner wall surface of the rubber roller forming table 11 by using a crane, so that the two ends of the high-precision rubber roller 14 are butt-jointed and positioned together with the surface of the second limiting rod 132. At this time, the surface of the rubber layer 141 is extruded and plastically deformed by the extrusion roller. According to the usage scenario of the high-precision rubber roller 14, the thickness of the rubber layer 141 can be maintained at the specified size required for the scenario. When the surface of the rubber layer 141 is extruded and formed, the motor three 13 is used to drive the transmission track 131 to rotate, which in turn drives the transmission gear teeth 133 and the second limiting rod 132 to rotate, so that the high-precision rubber roller 14 rotates rapidly on the inner wall surface of the rubber roller forming table 11. At this time, the motor one 116 rotates the lead screw, and the high-precision grinding knife 118 on the surface of the lead screw moves slowly under the limitation of the first limiting rod 117. When one end of the high-precision grinding knife 118 slides from one side to the other side on the surface of the rubber layer 141, the surface of the high-precision grinding knife 118 will cut and trim the excess rubber layer and some protruding rubber layers on the surface of the rubber layer 141. The cut rubber layer will fall into the inside of the rubber roller forming table 11 under the action of gravity for recycling; by using the slow movement of the high-precision grinding knife 118, while the high-precision rubber roller 14 rotates at a high speed driven by the motor three 13, the tip of the high-precision grinding knife 118 will repeatedly contact the same position on the surface of the rubber layer 141 for multiple times. Through repeated contact, the surface of the rubber layer 141 can be continuously cut and trimmed, thereby increasing the accuracy of the surface of the rubber layer 141.

[0023] Such as Figures 1 - 5 and Figures 8 to 10As shown in the figure, arc-shaped overlapping plates 113 are fixedly connected to the inner wall surfaces on both sides of the rubber roller forming table 11, and the positions of the arc-shaped overlapping plates 113 are set at the bottom edge positions of the high-precision rubber roller 14. Infrared heating rods 114 are fixedly installed on the inner wall surfaces on both sides of the rubber roller forming table 11, and the positions of the infrared heating rods 114 are set at the bottom edge positions of the arc-shaped overlapping plates 113. Groove openings 115 are formed on the top surfaces of the arc-shaped overlapping plates 113. A closing cover 119 is swingably connected to the top surface of the rubber roller forming table 11. Circulating fans 112 are fixedly installed on both side surfaces of the rubber roller forming table 11 and at the bottom edge positions. Support plates 126 are fixedly installed on both side surfaces of the rubber roller forming table 11 and at the two side edge positions of the limit grooves 111. A second motor 121 is fixedly installed on the top surface of the support plate 12. A threaded rod 122 is fixedly connected to the output end of the second motor 121. A slider 123 is threadedly movably sleeved on the outer surface of the threaded rod 122. A limit disk 124 is fixedly connected to one end of the slider 123. The outer surface of the limit disk 124 is movably lapped on the inner wall surface of the limit groove 111. An extrusion roller 125 is fixedly connected to the other side surface of the limit disk 124.

[0024] When the high-precision rubber roller 14 is clamped into the rubber roller forming table 11, the infrared heating rods 114 cooperate to perform high-temperature heating on the bottom surface of the rubber layer 141. The heated heat source will be transmitted upward through the groove openings 115, and the heat source will come into contact with the surface of the rubber layer 141, thereby softening the surface of the rubber layer 141. At this time, the second motor 121 is used to rotate the threaded rod 122, and the slider 123 and the limit disk 124 on the outer surface of the threaded rod 122 are driven to move together towards the rubber layer 141. When the extrusion roller 125 contacts the surface of the rubber layer 141, the rotation of the rubber layer 141 and the extrusion of the extrusion roller 125 will have the effect of plastically processing the surface of the rubber layer 141; When the rubber layer 141 is under the extrusion of the extrusion roller 125, some excess rubber layer 141 will be extruded and moved towards both ends of the high-precision rubber roller 14. The moving distance of the slider 123 can be used to control the thickness of the rubber layer 141, so that the rubber layer 141 can be more evenly and tightly attached to the surface of the high-precision rubber roller 14, thereby reducing the gap between the rubber layer 141 and the high-precision rubber roller 14 and increasing the adhesion force.

[0025] As Figures 6 to 9 and Figure 11 shown in the figure, a support rod 134 is fixedly connected to one side surface of the second limit rod 132. A rubber roller overlapping plate 135 is provided at one end of the support rod 134. A first hydraulic rod 136 is fixedly installed on the inner wall surface of the rubber roller overlapping plate 135. A semi-circular closing cover 137 that is movably lapped on the top surface of the rubber roller overlapping plate 135 is fixedly connected to the output end of the first hydraulic rod 136.

[0026] Lap both ends of the high-precision rubber roller 14 on the surface of the rubber roller lapping plate 135. At this time, cooperate with the first hydraulic rod 136 to move the semi-circular closed cover 137, and make the inner wall surface of the semi-circular closed cover 137 cover the outer surface of the top of the high-precision rubber roller 14. Use the rubber roller lapping plate 135 and the semi-circular closed cover 137 to wrap the surface of the high-precision rubber roller 14, thereby performing a limiting process on the position of the high-precision rubber roller 14, and at the same time preventing the high-precision rubber roller 14 from deviating and falling off at excessive positions when rotating.

[0027] Embodiment 2 As Figures 6 - 9 and Figure 11 As shown, in the automatic centering device for the high-precision rubber roller, two groups of second hydraulic rods 139 are fixedly installed on the outer surface of the second limiting rod 132. The positions of the second hydraulic rods 139 are set at the two side edges of the support rod 134. The output ends of the second hydraulic rods 139 are fixedly connected with lapping centering discs 1310 that are movably sleeved on the outer surface of the rubber roller lapping plate 135. The outer surface of the rubber roller lapping plate 135 is movably lapped on the outer surface of the rubber layer 141. Rectangular clamping columns 138 are fixedly connected to the inner wall surface of the semi-circular closed cover 137. Rectangular docking grooves 142 are formed on the two end surfaces of the high-precision rubber roller 14. The outer surface of the rectangular clamping column 138 is movably sleeved on the inner wall surface of the rectangular docking groove 142.

[0028] When the first hydraulic rod 136 pushes the semi-circular closed cover 137 to be clamped on the surface of the high-precision rubber roller 14, use the rectangular clamping column 138 inside the semi-circular closed cover 137 to be sleeved inside the rectangular docking groove 142, and use the shape of the rectangular clamping column 138 to increase the clamping force and adsorption force between it and the rectangular docking groove 142, so that the support rod 134 can provide torque when driving the high-precision rubber roller 14; When the surface of the rubber layer 141 is being extruded and shaped by the extrusion roller 125, when the excess rubber layer 141 transfers to both ends, cooperate with the second hydraulic rod 139 to push the lapping centering disc 1310, so that the lapping centering disc 1310 is sleeved on the surface of the rubber layer 141, and use the blocking of the lapping centering disc 1310 to block the rubber layer 141 when it is being deformed and extended. The blocked rubber layer 141 is repeatedly compressed by the extrusion roller 125 on the surface of the rubber layer 141, so that the rubber layer 141 can be more evenly and tightly attached to the surface of the high-precision rubber roller 14, thereby reducing the gap between the rubber layer 141 and the high-precision rubber roller 14 and increasing the adhesion effect.

[0029] Working principle: After the surface of the glue layer 141 is extruded and formed, the motor three 13 is coordinated to twist the transmission track 131, thereby driving the transmission gear teeth 133 and the limiting rod two 132 to rotate, so that the high-precision rubber roller 14 rotates rapidly on the inner side wall surface of the rubber roller forming table 11. At this time, the motor one 116 rotates the lead screw, and the high-precision grinding knife 118 on the surface of the lead screw moves slowly under the limitation of the limiting rod one 117. When one end of the high-precision grinding knife 118 slides from one side to the other side on the surface of the glue layer 141, the surface of the high-precision grinding knife 118 will cut and trim the excess glue layer and some protruding glue layers on the surface of the glue layer 141, and the cut glue layer will fall into the inside of the rubber roller forming table 11 under the action of gravity for recycling treatment; When the high-precision rubber roller 14 is clamped into the inside of the rubber roller forming table 11, the infrared heating rod 114 is coordinated to perform high-temperature heating on the bottom surface of the glue layer 141. The heated heat source will be transmitted through the slotted opening 115, and the heat source will contact the surface of the glue layer 141, thereby softening the surface of the glue layer 141. At this time, the motor two 121 rotates the threaded rod 122, and drives the slider 123 and the limiting disk 124 on the outer surface of the threaded rod 122 to move towards the glue layer 141. When the extrusion roller 125 contacts the surface of the glue layer 141, the rotation of the glue layer 141 and the extrusion of the extrusion roller 125 will perform a plastic treatment on the surface of the glue layer 141; When the surface of the glue layer 141 is being extruded and shaped by the extrusion roller 125, when the excess glue layer 141 transfers to both ends, the hydraulic rod two 139 is coordinated to push the overlapping centering disk 1310, so that the overlapping centering disk 1310 is sleeved on the surface of the glue layer 141, and the blocking of the overlapping centering disk 1310 is used to block the glue layer 141 when it is deformed and extended. The blocked glue layer 141 is repeatedly extruded by the extrusion roller 125, and the surface of the glue layer 141 will be repeatedly compressed, so that the glue layer 141 can be more evenly and tightly attached to the surface of the high-precision rubber roller 14, thereby reducing the gap between the glue layer 141 and the high-precision rubber roller 14 and increasing the adhesion effect.

Those skilled in the art should understand that the present invention is not limited by the above embodiments.
