Description

Technical Field

[0001] This utility model relates to the field of rubber blanket production technology, and specifically to a rubber blanket surface treatment device. Background Technology

[0002] The blanket is the covering material for the transfer cylinder on an offset printing press. It is a composite material product made of a rubber coating and a substrate. In indirect lithography, it is used to transfer ink from the printing plate to the substrate. After being coated with adhesive by a coating machine during production, the blanket needs to be dried.

[0003] Patent CN222039913U discloses a production equipment for a fully air-cushioned rubber blanket, comprising a base, a feeding mechanism on one side of the top of the base, a pressing mechanism in the middle of the top of the base, a drying mechanism on one side of the inner cavity of the pressing mechanism, and a winding mechanism on the other side of the top of the base. This invention, through the drying mechanism, dries the multi-layered fabric simultaneously from the top and bottom surfaces with hot air after pressing, resulting in faster adhesive curing and easier use. It eliminates the need for extensive waiting time for adhesive curing, thus increasing production efficiency. Furthermore, the adhesive nozzle is oriented between the pressure roller and the bearing roller, and the length of the nozzle is the same as the width of the fabric, ensuring more uniform adhesive spraying. Additionally, the pressure roller, during pressing, pushes a larger amount of adhesive from the front end of the fabric to the rear end, further improving adhesive uniformity.

[0004] However, in the prior art, during the drying process of the rubber blanket, the processed rubber blanket passes through the drying area in a straight line, which makes it difficult to extend the movement time of the rubber blanket inside the drying device. This results in a short drying time for the rubber blanket passing through the device, which may lead to the rubber blanket not being completely dried, thus affecting the drying quality of the rubber blanket.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0006] The purpose of this utility model is to provide a rubber sheet surface treatment device that can effectively solve the above-mentioned technical problems.

[0007] To achieve the purpose of this utility model, the following technical solution is adopted:

[0008] A rubber blanket surface treatment device includes: a drying oven; a plurality of mounting plates equidistantly fixed on both sides inside the drying oven; and an adjustment component for adjusting the drying time of the rubber blanket.

[0009] The adjusting assembly includes: an upper guide roller and a lower guide roller slidably mounted on the mounting plate, with the upper and lower guide rollers staggered vertically; a rack fixedly mounted on the upper and lower guide rollers; a gear shaft meshing with the rack, with one end of the gear shaft rotatably mounted on the mounting plate; connecting rods fixedly mounted on both ends of the upper guide roller; a connecting plate fixedly connected between multiple connecting rods; an electric cylinder that drives the connecting plate to rise and fall, and the electric cylinder is fixedly mounted on the drying chamber; and a drying assembly disposed on the upper and lower guide rollers to dry both sides of the rubber sheet.

[0010] Furthermore, both ends of the upper guide roller and the lower guide roller are fixedly installed with sliders, and the surface of the mounting plate is provided with a sliding groove that matches the sliders on the surfaces of the upper guide roller and the lower guide roller. The bottom of the connecting rod is fixedly connected to the adjacent slider, and the rack is fixedly installed on the adjacent slider.

[0011] Furthermore, guide rods are symmetrically fixedly connected to the top of the connecting plate, and the upper end of the guide rods can move through the top of the drying oven.

[0012] Furthermore, the drying assembly includes: an electric heating tube; movable blocks fixedly installed at both ends of the electric heating tube, and the movable blocks are slidably installed in corresponding grooves on the surface of the mounting plate; and a connecting column fixedly installed on the movable blocks, with one end of the connecting column fixedly connected to the adjacent slider.

[0013] Furthermore, through slots are provided on both sides of the drying box, and rollers are rotatably installed on both sides of the drying box near the through slots.

[0014] Compared with the prior art, the present invention has the following beneficial effects: When drying the rubber blanket, the distance between the upper and lower guide rollers in the drying chamber can be adjusted by adjusting the component settings, thereby extending or shortening the movement time of the rubber blanket inside the drying chamber, so as to adjust the drying time of the rubber blanket according to production needs. In addition, with the setting of the drying component, the electric heating tube can always maintain a certain distance from the conveyed rubber blanket, avoiding the distance between the electric heating tube and the upper or lower guide rollers being too close or too far after the upper and lower guide rollers are adjusted, which would cause uneven drying on both sides of the rubber blanket and affect the drying quality.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0023] like Figures 1 to 4 As shown, this utility model discloses a rubber blanket surface treatment device, comprising: a drying oven 1; a plurality of mounting plates 2 equidistantly fixedly installed on both sides inside the drying oven 1; and an adjustment component 3 for adjusting the drying time of the rubber blanket.

[0024] The adjusting assembly 3 includes: an upper guide roller 301 and a lower guide roller 302 slidably mounted on the mounting plate 2, with the upper guide roller 301 and the lower guide roller 302 arranged alternately; a rack 303 fixedly mounted on the upper guide roller 301 and the lower guide roller 302; a gear shaft 304 meshing with the rack 303, with one end of the gear shaft 304 rotatably mounted on the mounting plate 2; connecting rods 305 fixedly mounted on both ends of the upper guide roller 301; a connecting plate 306 fixedly connected between the multiple connecting rods 305; an electric cylinder 307 that drives the connecting plate 306 to rise and fall, and the electric cylinder 307 is fixedly mounted on the drying chamber 1; and a drying assembly 4 disposed on the upper guide roller 301 and the lower guide roller 302 to dry both sides of the rubber sheet.

[0025] When drying the rubber blanket, it is laid out in a wavy shape in the drying chamber 1. When the drying time of the rubber blanket needs to be increased, the electric cylinder 307 is activated. The output end of the electric cylinder 307 drives the connecting rod 305 fixed at the bottom of the connecting plate 306 to move upward, causing the connecting rod 305 to drive the upper guide roller 301 to rise. At this time, the slider at the end of the upper guide roller 301 drives the rack 303 to move, so that the rack 303 meshes with the gear shaft 304. At the same time, the gear shaft 304 meshes with the rack 303 fixed at the end of the lower guide roller 302, so that the rack 303 drives the lower guide roller 302 to move downward. The increased distance between the upper guide roller 301 and the lower guide roller 2 indirectly prolongs the movement time of the rubber sheet inside the drying chamber 1, resulting in a longer drying time for the rubber sheet passing through the drying chamber 1 by the electric heating tube 401. When it is necessary to shorten the drying time of the rubber sheet according to the requirements, the output end of the electric cylinder 307 pushes the connecting plate 306 downward, causing the rack 303 on the upper guide roller 301 to mesh with the gear shaft 304. The gear shaft 304 reverses, driving the lower guide roller 302 upward. At this time, the movement time of the rubber sheet inside the drying chamber 1 is indirectly shortened, thereby achieving the purpose of shortening the drying time of the rubber sheet.

[0026] It should be noted that both ends of the upper guide roller 301 and the lower guide roller 302 are fixedly mounted with sliders. The surface of the mounting plate 2 is provided with grooves that cooperate with the sliders on the surfaces of the upper guide roller 301 and the lower guide roller 302. The bottom of the connecting rod 305 is fixedly connected to the adjacent slider, and the rack 303 is fixedly mounted on the adjacent slider. The sliders at both ends of the upper guide roller 301 and the lower guide roller 302 are slidably mounted in the grooves on the mounting plate 2, which improves the stability of the movement of the upper guide roller 301 and the lower guide roller 302.

[0027] It should be added that the top of the connecting plate 306 is symmetrically and fixedly connected with guide rods 3061, and the upper end of the guide rods 3061 can move through the top of the drying oven 1; the guide rods 3061 are set to improve the stability of the connecting plate 306 when it is raised and lowered.

[0028] To prevent the electric heating tube 401 from being too close or too far from the rubber sheet after the upper guide roller 301 and lower guide roller 302 are adjusted in position, the drying assembly 4 includes: an electric heating tube 401; movable blocks 402 fixedly installed at both ends of the electric heating tube 401, and the movable blocks 402 are slidably installed in the corresponding grooves on the surface of the mounting plate 2; and a connecting post 403 fixedly installed on the movable blocks 402, with one end of the connecting post 403 fixedly connected to an adjacent slider.

[0029] Since the electric heating tube 401 is fixedly installed on the upper guide roller 301 and the lower guide roller 302 via the connecting column 403 fixed on the moving block 402, when the distance between the upper guide roller 301 and the lower guide roller 302 changes, the electric heating tube 401 can move accordingly with the movement of the upper guide roller 301 and the lower guide roller 302, so that the electric heating tube 401 can always maintain a certain distance from the conveyed rubber sheet. This avoids the electric heating tube 401 from being too close or too far from the upper guide roller 301 or the lower guide roller 302 after the upper guide roller 301 and the lower guide roller 302 have been adjusted, which would cause uneven drying on both sides of the rubber sheet and affect the drying quality.

[0030] It should be added that both sides of the drying chamber 1 are provided with through slots, and idlers are rotatably installed on both sides of the drying chamber 1 near the through slots; the idlers near the through slots guide the conveyed rubber sheet.

[0031] Working principle: When the power is turned on, the rubber blanket is laid out in a wavy shape in the drying chamber 1 during the drying process. When it is necessary to increase the drying time of the rubber blanket, the electric cylinder 307 is activated. The output end of the electric cylinder 307 drives the connecting rod 305 fixed at the bottom of the connecting plate 306 to move upward, causing the connecting rod 305 to drive the upper guide roller 301 to rise. At this time, the slider at the end of the upper guide roller 301 drives the rack 303 to move, so that the rack 303 meshes with the gear shaft 304. At the same time, the gear shaft 304 meshes with the rack 303 fixed at the end of the lower guide roller 302, causing the rack 303 to drive the lower guide roller 302 to move downward. The increased distance between the lower guide roller 302 and the upper guide roller 301 indirectly prolongs the movement time of the rubber sheet inside the drying chamber 1, resulting in a longer drying time for the rubber sheet passing through the drying chamber 1 by the electric heating tube 401. When it is necessary to shorten the drying time of the rubber sheet according to the requirements, the output end of the electric cylinder 307 pushes the connecting plate 306 downward, causing the rack 303 on the upper guide roller 301 to mesh with the gear shaft 304. The gear shaft 304 reverses, driving the lower guide roller 302 upward. At this time, the movement time of the rubber sheet inside the drying chamber 1 is indirectly shortened, thereby achieving the purpose of shortening the drying time of the rubber sheet.
