Description

Technical Field

[0001] This utility model relates to the field of printer rubber roller production and processing technology, and in particular to a lifting device for baking printer rubber rollers. Background Technology

[0002] Printer rollers require a baking and shaping process during production. Typically, the rollers are placed on multi-layer baking racks and then placed in an oven for baking and shaping. However, in existing technology, the rollers are fed into the oven via a conveyor belt. This requires manual labor to place the rollers one by one onto the baking racks, a time-consuming and labor-intensive process that is both inefficient and demanding.

[0003] To address this issue, we propose a lifting device for baking printer rollers. Utility Model Content

[0004] The purpose of this invention is to provide a lifting device for baking printer rollers, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A lifting device for baking printer rollers includes a conveyor belt for conveying the rollers, a baking rack for layering the rollers, and a lifting mechanism for lifting the baking rack. The baking rack has multiple layers of support rods along the vertical direction, and each support rod has several limiting grooves equidistantly spaced along its length. An inclined guide plate is provided between the conveyor belt and the baking rack. The lifting mechanism includes a base frame and a control box. A bracket is mounted on the base frame via a vertical screw module, and a support plate is mounted on the support plate via a horizontal screw module parallel to the conveyor belt's conveying direction. The support plate is supported at the bottom of the baking rack.

[0007] In a further embodiment, the conveyor belt is provided with arc-shaped supports at equal intervals, and the axial spacing of the conveyor belt is smaller than the spacing of the inclined guide plates and also smaller than the spacing between two support rods in the same layer.

[0008] In a further embodiment, the bottom surface of the baking rack is provided with a cross groove, and the top surface of the tray is provided with a cross protrusion that matches and engages with the cross groove.

[0009] In a further embodiment, casters are installed at all four corners of the bottom of the baking rack.

[0010] In a further embodiment, the horizontal lead screw module includes a lead screw, a slide block threaded onto the lead screw, and a servo motor for driving the lead screw to rotate. The support plate and the bracket are also provided with multiple sets of sliding rails and sliders, and the sliding direction of the rails and sliders is parallel to the axis of the lead screw.

[0011] In a further embodiment, the vertical lead screw module includes a second lead screw, a second slide block threaded onto the second lead screw, and a second servo motor for driving the second lead screw to rotate. The base frame is also provided with multiple sets of sliding rods and slide sleeves that are slidably connected, and the sliding direction of the sliding rods and slide sleeves is parallel to the axial direction of the second lead screw.

[0012] In a further embodiment, both slide one and slide two are embedded with a distance measuring sensor. The detection direction of the distance measuring sensor is consistent with the sliding direction of the slide, and the distance measuring sensor is electrically connected to the control box.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention features a baking rack positioned on the discharge side of a conveyor belt via a lifting mechanism, guided by an inclined guide plate. The horizontal screw module in the lifting mechanism moves the baking rack closer to or further away from the discharge side of the conveyor belt, allowing the rubber rollers to be arranged on the same layer of support rods. The vertical screw module in the lifting mechanism raises and lowers the baking rack, thereby switching the support rods of different layers to align with the discharge side of the conveyor belt for receiving materials. This achieves automatic conveying, guiding, and layered placement of the rubber rollers, effectively reducing manual intervention in placement and increasing efficiency. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 A lifting device for baking a printer roller includes a conveyor belt 1, a baking rack 2 and a lifting mechanism. The conveyor belt 1 is a structure of two parallel narrow belts. Arc-shaped supports 11 are provided at equal intervals along the transmission direction on the conveyor belt 1. The arc-shaped supports 11 on the two narrow belts are positioned opposite each other and are used to support the same roller.

[0024] The baking rack 2 has a multi-layer frame structure, with two parallel support rods 3 on each layer. The support rods 3 have limit grooves 31 for fixing the position of the rubber rollers. The bottom of the baking rack 2 has a cross groove 21 for quick positioning and assembly with the lifting mechanism. The four corners of the bottom of the baking rack 2 are equipped with casters 12 for easy movement.

[0025] An inclined guide plate 4 is provided on the frame at the discharge end of the conveyor belt 1. The inclined angle allows the rubber roller to slide into the corresponding layer of the baking rack 2 by gravity. The axial spacing of the conveyor belt 1 is designed to be smaller than the spacing of the inclined guide plate 4 and the spacing of the support rod 3 in the same layer, so as to ensure that the rubber roller can slide into the baking rack 2 smoothly.

[0026] The lifting mechanism is supported by a base frame 8, on which a bracket 6 is mounted via a vertical lead screw module 9. The vertical lead screw module 9 includes a second lead screw 91, a second slide block 92, and a second servo motor 93. The second lead screw 91 is rotatably connected to the base frame 8, and the second servo motor 93 is fixedly mounted on the top of the base frame 8. The output shaft of the second servo motor 93 is connected to the end of the second lead screw 91 via a coupling. The second slide block 92 is threaded onto the outside of the second lead screw 91 and extends to the bottom of the bracket 6 to support it. A slide rod 15 parallel to the second lead screw 91 is also provided between the base frames 8. A sliding sleeve 16 is embedded in the second slide block 92, and the slide rod 15 slides through the interior of the sliding sleeve 16 to ensure the stability of vertical movement. The bracket 6 is supported by a horizontal lead screw module... The mounting plate 5 is installed in group 7. The cross-shaped protrusion 51 on the mounting plate 5 can be engaged with the cross groove 21 at the bottom of the baking rack 2 for precise positioning. The horizontal lead screw module 7 includes a lead screw 71, a slide block 72 and a servo motor 73. The lead screw 71 is rotatably connected to the bracket 6. The servo motor 73 is fixed to the outer wall of the bracket 6, and the output shaft of the servo motor 73 is connected to the end of the lead screw 71 through a coupling. The slide block 72 is threaded onto the outside of the lead screw 71 and is fixedly connected to the bottom of the mounting plate 5. A straight rail 13 parallel to the axis of the lead screw 71 is also fixed on the bracket 6. A slider 14 is slidably connected on the straight rail 13 and is fixedly connected to the bottom of the mounting plate 5 to enhance horizontal guidance.

[0027] Furthermore, a control box 10 is installed on the side wall of the base frame 8. Distance sensors 17 are embedded on both slide 1 72 and slide 2 92 to detect the moving distance of slide 1 72 and slide 2 92 and transmit the signal to the controller in the control box 10 to realize closed-loop control.

[0028] Workflow: The empty baking rack 2 is pushed to the lifting station by its casters 12 at the bottom, aligning and engaging the cross groove 21 at the bottom of the baking rack 2 with the cross protrusion 51 on the lifting mechanism support plate 5, thus achieving precise positioning. Driven by the vertical screw module 9, the lifting mechanism support plate 5 adjusts its initial height so that the lowest support rod 3 of the baking rack 2 is exactly at the lower end of the outlet of the inclined guide plate 4. The horizontal distance is adjusted by the horizontal screw module 7 so that the rightmost limiting groove 31 is aligned with the lower edge of the outlet of the inclined guide plate 4, ready to receive the rubber roller. The conveyor belt 1 starts, with equidistant arcs on it... The support 11 conveys the rubber rollers forward one by one. After being delivered to the end of the conveyor belt 1, the rubber rollers slide naturally onto the inclined guide plate 4 under gravity. The rubber rollers slide down the inclined guide plate 4 and accurately slide into the corresponding limiting grooves 31 of the two uppermost support rods 3 of the baking rack 2, which are already aligned, thus completing the placement of the first rubber roller. After the placement of one rubber roller is completed, the control box 10 issues a command, and the horizontal screw module 7 works to drive the support plate 5 and the entire baking rack 2 on it to move a fixed distance along the direction of the support rods 3, that is, the conveying direction of the conveyor belt 1, that is, the two adjacent limiting grooves 31 on the same layer. The distance is measured by the distance sensor 17, which provides real-time feedback on the moving distance to ensure accurate positioning. After the roller is in place, the conveyor belt 1 sends the next roller, which falls into the adjacent limiting groove 31. This "placement-lateral movement" process is repeated until all the limiting grooves 31 of the entire layer of support rods 3 are filled with rollers. When one layer is full, the control box 10 controls the vertical screw module 9 to work. The vertical screw module 9 drives the entire bracket 6, support plate 5, and baking rack 2 to descend precisely by one layer height, that is, the vertical distance between the upper and lower support rods 3. Similarly, the distance sensor 17 ensures that the descent distance is accurate. If an error occurs, the next layer of support rod 3 is precisely aligned with the outlet of the inclined guide plate 4. At the same time, the horizontal screw module 7 drives the baking rack 2 to reset to the starting position of that layer. The above steps are repeated in a cycle, and the rubber rollers are automatically and neatly placed on each layer of the baking rack 2 from bottom to top until the entire baking rack 2 is filled. After it is filled, the lifting mechanism lowers the baking rack 2 to the bottom, and the operator can easily push the entire baking rack 2 filled with rubber rollers away from the support plate 5 through the casters 12 and transfer it into the oven for baking. Then, a new empty baking rack 2 can be pushed into the work station to start the next cycle.
