Description

Technical Field

[0001] This invention relates to the field of textile machinery technology, and more specifically to a coating equipment for rubber rollers. Background Technology

[0002] Rubber rollers are roller-shaped products made by vulcanizing rubber with metal or other materials as the core. They can be classified according to their use as papermaking rubber rollers, dyeing and printing rubber rollers, etc. In the textile process, the surface of the rubber roller needs to be coated to facilitate its use.

[0003] A published Chinese patent, publication number CN219923545U, discloses a general-purpose automatic coating and tray-loading machine for rubber rollers. The machine includes a support platform, a worktable, and a rubber roller processing structure installed on top of the support platform and worktable. The rubber roller processing structure includes: a placement tray placed above the support platform, containing rubber rollers evenly and regularly arranged within the tray; and a gripping structure installed on the top and bottom of the inner wall of the support platform. The machine uses mechanical grippers to transfer the rubber rollers between different workstations and employs transfer racks and lifting frames to assist in loading and unloading, achieving preliminary automation of the rubber roller coating process. However, this solution still has the following shortcomings: 1. Dust, oil and other impurities generated during production and storage easily adhere to the surface of the rubber roller sleeve. Existing equipment directly applies coatings, resulting in poor adhesion between the coating and the roller sleeve, which easily peels off and flakes. Furthermore, when the roller sleeve has high hardness, the coating is difficult to penetrate and adhere, resulting in uneven coating thickness and a rough surface.

[0004] 2. Existing equipment only uses two abutments to hold the rubber roller during coating, lacking a dedicated pressing mechanism. During the rotation of the rubber roller, axial displacement or radial runout is prone to occur, affecting the uniformity of the coating. Summary of the Invention

[0005] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a rubber roller coating equipment to solve the problems of impurities adhering to the surface of the rubber roller sleeve affecting the coating effect when the existing equipment directly performs coating operations, and the problems of axial displacement or radial runout easily occurring during the rotation of the rubber roller when the existing equipment only uses two abutment rods to hold the rubber roller during coating.

[0006] To achieve the above and other related objectives, the present invention provides a roller coating equipment, including a machine body, wherein a loading and unloading assembly is provided on one side of the machine body and a processing assembly is provided on the other side, and a material transfer assembly is provided at the upper end of the machine body, wherein the material transfer assembly is movably fitted between the loading and unloading assembly and the processing assembly; The processing assembly includes a worktable, on which a transfer feeding mechanism, a coating mechanism, and a pressing mechanism are mounted. The coating mechanism is located at the end of the transfer feeding mechanism away from the loading and unloading assembly, and the pressing mechanism is located below the coating mechanism for pressing the roller shaft of the rubber roller.

The pressure plate is hinged to the first and third connecting rods by a pin, and the end of the pressure plate near the feeding rack can be flipped and fitted on the coating station.

[0010] In one embodiment of the present invention, the roller sleeve cleaning mechanism includes: A first rotary motor, with a first rotary assembly mounted on its output end; The second lifting cylinder is located on one side of the first rotary motor; A grinding component is mounted on the output end of a second lifting cylinder and is height-adjustable above the cleaning station.

[0011] In one embodiment of the present invention, the roller sleeve heating mechanism includes: A heating box, wherein the heating box is provided with a heating port, which is fitted to the side end of the heating station; The output end of the Y-axis propulsion cylinder is connected to the heating box.

[0012] In one embodiment of the present invention, the roller rotation mechanism includes a second rotary motor, and a second rotary assembly is mounted on the output end of the second rotary motor. The second rotary assembly is fitted to the side end of the coating station.

[0013] In one embodiment of the present invention, the material transfer mechanism includes: An X-axis linear module, which is connected above the material feeding assembly and the processing assembly; The second Z-axis linear module is assembled on the movable end of the X-axis linear module; A gripper unit is mounted on the movable end of the second Z-axis linear module.

[0014] In one embodiment of the present invention, the loading and unloading assembly includes: A loading platform, on which material trays are stacked and rubber rollers are placed on the material trays; Two sets of feeding mechanisms are distributed on opposite left and right sides of the loading platform, used to lift the material tray and cooperate with the material transfer mechanism to pick up the material; Both sets of feeding mechanisms are identical and include: The third Y-axis linear module is located below the loading platform; The third Z-axis linear module, on the movable end of the third Y-axis linear module; A clamping cylinder is mounted on the movable end of the third Z-axis linear module; the output end of the clamping cylinder is equipped with a clamping seat, which can movably engage the side end of the material tray.

[0016] As described above, the roller coating equipment of the present invention has the following beneficial effects: 1. This invention, by setting up a roller sleeve cleaning mechanism, a roller sleeve heating mechanism, and a pressing mechanism, allows the roller sleeve cleaning mechanism to remove impurities from the surface of the rubber roller before coating, preventing coating peeling due to impurities and improving the coating effect. The roller sleeve heating mechanism heats and softens the roller sleeve before coating, improving the coating penetration and adhesion, ensuring a uniform coating that is not prone to peeling. The pressing mechanism adopts a multi-link flipping structure, which can achieve smooth lifting and flipping of the pressing plate in a limited space.

[0017] 2. The pressing mechanism used in this invention works in conjunction with the first, second, and third connecting rods to enable the pressing plate to move along an arc and press the roller shaft of the rubber roller from top to bottom, providing only downward pressure. Compared with the prior art, which has no horizontal force, this improves the pressing and positioning effect on the rubber roller and reduces friction.

[0018] 3. The transfer and feeding mechanism designed in this invention adopts an inclined feeding rack. The inclined feeding rack can realize automatic rolling and positioning of the rubber roller, reduce mechanical transmission parts, and reduce the failure rate. At the same time, cleaning, heating, and coating multiple stations are integrated on the inclined feeding rack. The lifting frame realizes the automatic switching of the rubber roller between each station through the top part, without the need for an additional transfer mechanism, reducing process connection time and improving production efficiency.

[0019] 4. The coating mechanism designed in this invention adopts a combination design of Y-axis opening and closing module and two sets of Z-axis linear modules. The coating head is driven by a conveyor belt to separate or aggregate synchronously. With the Z-axis height adjustment, it can accurately adapt to coating rollers of various diameters. One structure has multiple uses and saves production costs.

[0020] 5. This solution integrates tray lifting, roller gripping and handling, pretreatment, coating, and tray loading functions. The entire process requires no manual intervention. Only periodic tray replenishment is needed to achieve continuous production, reduce manual operation, significantly reduce labor costs, and meet the needs of large-scale industrial production.

[0035] Please see Figures 1-3This invention provides a coating equipment for rubber rollers, including a machine body 1. One side of the machine body 1 is provided with a loading / unloading assembly, and the other side with a processing assembly. The upper end of the machine body 1 is provided with a material transfer assembly 2. The material transfer assembly 2 includes an X-axis linear module 21, a second Z-axis linear module 22, and a gripper unit 23. The gripper unit 23 consists of a gripper cylinder and a pair of grippers mounted on the output end of the gripper cylinder. The gripper cylinder drives the grippers to separate and reassemble to pick up and place the rubber rollers. The X-axis linear module 21 spans above the loading / unloading assembly and the processing assembly. The second Z-axis linear module 22 is mounted on the movable end of the X-axis linear module 21, and the gripper unit 23 is mounted on the movable end of the second Z-axis linear module 22. The material transfer assembly 2 provides linear driving force in the X and Z axes through the cooperation of the X-axis linear module 21 and the second Z-axis linear module 22, enabling the gripper unit 23 to move and cooperate between the loading / unloading assembly and the processing assembly to pick up and place materials quickly and accurately. The processing assembly includes a workbench 3, on which a transfer feeding mechanism 4, a coating mechanism 5, and a pressing mechanism 9 are mounted. The coating mechanism 5 is located at the end of the transfer feeding mechanism 4 away from the loading and unloading assembly, and the pressing mechanism 9 is located below the coating mechanism 5 for pressing the roller shaft of the rubber roller. The workbench 3 has two sets of Y-axis linear modules 12 symmetrically distributed relative to the transfer feeding mechanism 4. Each set of Y-axis linear modules 12 has a movable plate 13 on its movable end, and each movable plate 13 is equipped with roller sleeves arranged sequentially along the feeding direction of the transfer feeding mechanism 4. The system includes a cleaning mechanism 6, a roller sleeve heating mechanism 7, and a rubber roller rotating mechanism 8. The cleaning mechanism 6 cleans the surface of the rubber roller sleeve, the heating mechanism 7 softens the rubber roller sleeve by heating it, and the rotating mechanism 8 rotates the roller shaft to cooperate with the coating mechanism 5 to apply coating to the surface of the roller sleeve. This solution also integrates functions such as tray lifting, rubber roller gripping and handling, pretreatment, coating, and unloading. The entire process requires no manual intervention and only requires periodic replenishment of the tray to achieve continuous production, reducing manual operation, significantly lowering labor costs, and meeting the needs of large-scale industrial production.

[0036] Please see Figures 4-9The transfer and loading mechanism 4 includes a base 41, a feeding rack 42, a lifting frame 43, and a lifting cylinder 44. The base 41 is mounted on the workbench 3. The feeding rack 42 is mounted on the base 41 and is gradually inclined downwards along the loading direction. The feeding rack 42 is provided with a cleaning station 421, a heating station 422, and a coating station 423. The lifting frame 43 is height-adjustable and fitted into the feeding rack 42. The lifting frame 43 is provided with multiple top-loading parts 431 that are sequentially fitted into the cleaning station 421, the heating station 422, and the coating station 423. The lifting cylinder 44 is mounted on the workbench 3. Located on one side of the base 41, the lifting frame 43 is connected to the output end of the lifting cylinder 44; the roller sleeve cleaning mechanism 6, the roller sleeve heating mechanism 7, and the rubber roller rotating mechanism 8 are respectively set for the cleaning station 421, the heating station 422, and the coating station 423. The lifting frame 43 is driven to rise by the lifting cylinder 44. With the help of the inclined feeding frame 42, the rubber roller can automatically roll and switch between each station, realize continuous and gradual feeding between multiple stations, reduce the process connection time, and improve production efficiency; this mechanism does not require an additional transfer mechanism, reduces mechanical transmission parts, and reduces the failure rate.

[0037] The coating mechanism 5 includes a Y-axis opening and closing module 51, two Z-axis linear modules 52, and two paint boxes 53. The Y-axis opening and closing module 51 uses a circumferentially closed conveyor belt 511. The two Z-axis linear modules 52 are respectively mounted on the upper and lower ends of the conveyor belt 511. The conveyor belt 511 rotates unidirectionally to simultaneously drive the two Z-axis linear modules 52 to separate and merge. Each paint box 53 is mounted on the movable end of one Z-axis linear module 52. A paint head 54 is mounted on the lower end of the paint box 53, and the paint head 54 is positioned above the coating station 423. The coating mechanism 5 designed in this invention uses a combination design of the Y-axis opening and closing module 51 and two Z-axis linear modules 52 to drive the paint box 53 in both the Y and Z axes. The Y-axis opening and closing module 51 drives the paint box 53 and paint head 54 to separate or merge synchronously via the conveyor belt 511. With Z-axis height adjustment, it can accurately adapt to paint rollers of various diameters, making it a multi-purpose structure that saves production costs.

[0038] The pressing mechanism 9 includes a third lifting cylinder 91, a first connecting rod 93, a second connecting rod 94, a third connecting rod 95, and a pressure plate 96. A rectangular block 92 is located at the output end of the third lifting cylinder 91. The first connecting rod 93 is hinged to the end of the rectangular block 92 away from the feeding rack 42 via a pin. The second connecting rod 94 is hinged to the end of the rectangular block 92 near the feeding rack 42 via a pin. The third connecting rod 95 is hinged to the upper end of the cylinder body of the third lifting cylinder 91 via a pin. The upper end of the second connecting rod 94 is hinged to the third connecting rod 95 via a pin. The pressure plate 96 is hinged to the first connecting rod 93 and the third connecting rod 95 via pins. The third lifting cylinder 91 provides driving force, causing the first connecting rod 93, hinged to the rectangular block 92, to lift, thereby lifting the end of the pressure plate 96 away from the feeding rack 42. The second connecting rod 94 and the third connecting rod 95 cooperate to form the pressure plate 96. The plate body of 6 provides stable support without affecting the flipping of the pressure plate 96. The end of the pressure plate 96 near the feeding rack 42 can be flipped to cooperate with the coating station 423 to limit the rotation of the roller shaft of the rubber roller placed in the coating station 423. The pressing mechanism 9 adopts a multi-link flipping structure, which can realize the smooth lifting and flipping of the pressure plate 96 in a limited space. The structure is compact and the operation is reliable. With the cooperation of the rubber roller rotation mechanism 8, it can ensure the coaxiality of the rubber roller during rotation, avoid the coating skewing caused by axial offset, and significantly improve the qualified rate of the rubber roller coating. The pressing mechanism 9 is linked by the first link 93, the second link 94, and the third link 95, so that the pressure plate 96 can move along the arc from top to bottom to press the roller shaft of the rubber roller. It only provides downward pressure. Compared with the existing technology that has no horizontal force, it improves the pressing and positioning effect of the rubber roller and reduces friction.

[0039] The roller sleeve cleaning mechanism 6 includes a first rotary motor 61, a second lifting cylinder 63, and a grinding component 64. A first rotating assembly 62 is mounted on the output end of the first rotary motor 61. The second lifting cylinder 63 is located on one side of the first rotary motor 61. The grinding component 64 is mounted on the output end of the second lifting cylinder 63 and is vertically movably positioned above the cleaning station 421. The second lifting cylinder 63 drives the grinding component 64 to a suitable height, and the first rotary motor 61 drives the first rotating assembly. 62 drives the rubber roller to rotate, so that the roller sleeve contacts the grinding part 64 to grind and clean the surface impurities; the roller sleeve heating mechanism 7 includes a heating box 71 and a Y-axis propulsion cylinder 72. The heating box 71 is provided with a heating port 711, which is fitted to the side end of the heating station 422. The output end of the Y-axis propulsion cylinder 72 is connected to the heating box 71. The Y-axis propulsion cylinder 72 pushes the heating box 71 closer to the rubber roller, so that the roller sleeve of the rubber roller is fully inserted into the heating port 711 so as to uniformly heat the roller sleeve. The roller rotation mechanism 8 includes a second rotary motor 81, and a second rotary assembly 82 is mounted on the output end of the second rotary motor 81. The second rotary assembly 82 is fitted to the side of the coating station 423. The second rotary motor 81 drives the second rotary assembly 82 to rotate the roller, which works in conjunction with the coating mechanism 5 to apply the coating. This invention, by setting up a roller sleeve cleaning mechanism 6, a roller sleeve heating mechanism 7, and a roller rotation mechanism 8, allows the roller sleeve cleaning mechanism 6 to remove impurities from the surface of the roller before coating, preventing the coating from peeling off due to impurities and improving the coating effect. The roller sleeve heating mechanism 7 heats and softens the roller sleeve before coating, improving the coating penetration and adhesion, ensuring a uniform coating that is not prone to peeling. The synergistic effect of the pressing mechanism 9 and the roller rotation mechanism 8 ensures the coaxiality of the roller during rotation, preventing axial displacement that could cause coating skewing and significantly improving the product qualification rate.

[0040] Please see Figures 10-11The loading and unloading assembly includes a loading platform 11 and two sets of feeding mechanisms 14. A material tray 10 is stacked on the loading platform 11, and a rubber roller is placed on the material tray 10. The two sets of feeding mechanisms 14 are distributed on opposite left and right sides of the loading platform 11, and are used to lift the material tray 10 to cooperate with the material transfer mechanism 2 to pick up the material. Both sets of feeding mechanisms 14 are identical, each including a third Y-axis linear module 141, a third Z-axis linear module 142, and a clamping cylinder 143. The third Y-axis linear module 141 is located below the loading platform 11, and the third Z-axis linear module 142 is located on the movable end of the third Y-axis linear module 141. The clamping cylinder 143 is mounted on the movable end of the third Z-axis linear module 142. The output end of the clamping cylinder 143 is equipped with a clamping seat 144, which can movably engage the side end of the material tray 10. Specifically, the clamping seat 144 includes an L-shaped clamping plate 1441 and an inverted V-shaped clamping block 1442. The L-shaped clamping plate 1441 is positioned at the lower end of the material tray 10, and the inverted V-shaped clamping block 1442 abuts against the upper end of the material tray 10. During the feeding process, the feeding mechanism 14 provides driving forces along the Y, Z, and X axes through the third Y-axis linear module 141, the third Z-axis linear module 142, and the clamping cylinder 143. This allows the clamping seat 144 to movably engage the side end of the material tray 10. The L-shaped clamping plate 1441 of the clamping seat 144 is positioned at the lower end of the material tray 10, and the inverted V-shaped clamping block 1442 gradually abuts against the upper end of the material tray 10 as the pushing cylinder 63 advances, effectively preventing the material tray 10 from shifting and ensuring feeding stability. This invention uses a loading and unloading assembly in conjunction with a processing assembly. In the loading and unloading assembly, the feeding mechanism can sequentially remove the material trays from top to bottom on the unloading platform and lift them to the appropriate position according to the processing progress. Furthermore, the feeding mechanism can move and stack the material trays along the Y-axis according to the material processing status in the trays. The material transfer mechanism can simultaneously pick up and place materials in the loading and unloading assembly, realizing continuous coating operations for the rubber rollers, significantly improving production efficiency, and meeting the large-scale, high-frequency coating needs of the rubber rollers.

[0041] When this equipment is working, the rubber rollers automatically complete the coating process according to the following procedure: 1) Loading stage: The material trays 10 stacked on the loading platform 11 are lifted layer by layer to the picking height by two sets of feeding mechanisms 14; the gripper unit 23 in the transfer assembly 2, driven by the X-axis linear module 21 and the Z-axis linear module 22, grabs the rubber roller and transfers it to the feeding rack 42 of the transfer loading mechanism 4.

[0042] 2) Transfer and pre-treatment stage: The rubber roller automatically rolls to the cleaning station 421 on the inclined feeding rack 42; the lifting cylinder 44 pushes the lifting frame 43 to rise, so that the top part 431 lifts the rubber roller; at this time, the grinding part 64 in the roller sleeve cleaning mechanism 6 descends under the drive of the second lifting cylinder 63 to grind and clean the surface of the rubber roller; then the rubber roller enters the heating station 422, and the heating box 71 in the roller sleeve heating mechanism 7 approaches the rubber roller under the push of the Y-axis propulsion cylinder 72, and softens the rubber roller sleeve through the heating port 711.

[0043] 3) Coating Stage: After the rubber roller enters the coating station 423, the pressing mechanism 9 is activated, and the third lifting cylinder 91 pushes the rectangular block 92 to rise. Through the linkage of the first connecting rod 93, the second connecting rod 94, and the third connecting rod 95, the pressure plate 96 flips and presses the rubber roller shaft. At the same time, the second rotary motor 81 in the rubber roller rotating mechanism 8 drives the second rotating assembly 82 to rotate the rubber roller at a uniform speed. In the coating mechanism 5, the Y-axis opening and closing module 51 synchronously drives the two sets of Z-axis linear modules 52 to close towards the middle through the conveyor belt 511, so that the two sets of coating heads 54 are precisely aligned with the two ends of the rubber roller. The coating in the coating box 53 is evenly coated on the surface of the rotating rubber roller through the coating heads 54.

[0044] 4) Material feeding and circulation: After the coating is completed, the pressing mechanism 9 resets, and the material transfer component 2 picks it up and puts it back into the material tray 10. The equipment continues to operate in a cycle, realizing continuous automated production.

[0045] In summary, this invention, through its fully automated design integrating roller sleeve cleaning, heating and softening, coating, and pressing, performs surface pretreatment before coating the rubber rollers, significantly improving the uniformity and quality of coating adhesion. The invention employs a transfer feeding system combined with inclined feeding, multi-link pressing, and synchronous opening and closing of the coating head, effectively improving production efficiency and automation. This solution requires no manual intervention throughout the entire process; continuous production can be achieved simply by periodically replenishing the material tray, reducing manual operation and significantly lowering labor costs, thus meeting the needs of large-scale industrial production. Therefore, this invention effectively overcomes the various shortcomings of existing technologies and possesses high industrial application value.

[0046] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
