Abstract
Description
Technical Field
[0001] This utility model relates to the field of cardboard lamination technology, and in particular to a gluing and lamination device for cardboard processing. Background Technology
[0002] In the manufacture of multi-layer paperboard, gluing can firmly bond the layers of paperboard together and improve the strength and stability of the paperboard, enabling it to withstand greater pressure and weight. After gluing, in order to increase the intermolecular forces between the glue and the paperboard, a hydraulic press is needed to press the glued paperboard, thereby effectively improving the tightness of the paperboard bonding process.
[0003] Currently, existing hydraulic pressing machines have a relatively simple overall structure. During the pressing process, workers need to place multiple layers of cardboard on the machine's support platform, which is exposed. Due to the complex workshop environment, dust, debris, and particles from the workshop air will fall onto the support platform when the machine is not in use. To prevent the pressed cardboard from becoming uneven, workers need to manually clean the support platform. However, since the support platform is relatively large, manual cleaning is time-consuming and labor-intensive. Therefore, we propose a cardboard gluing and pressing device to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a gluing and pressing device for cardboard processing.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A cardboard coating and pressing device includes a pressing machine base, a hydraulic assembly installed above the pressing machine base, an extension plate provided on the back of the pressing machine base, a connecting block connected to the side of the extension plate, a cylinder connected to the front of the connecting block, and a scraper distributed at the other end of the cylinder.
[0007] Preferably, the front side of the pressing machine is provided with a collection frame, and the opening length at the top of the collection frame is greater than the lateral length of the scraper.
[0008] Preferably, the front of the pressing machine is connected to a tray, and the upper side of the tray is symmetrically connected to connecting strips, and the bottom of the collection frame is provided with a slide that matches the connecting strips.
[0009] Preferably, the collecting frame has grooves on its side, and the grooves are symmetrically distributed at the left and right ends of the collecting frame.
[0010] Preferably, a rotating shaft is inserted inside the extension plate, and both ends of the rotating shaft are inserted into the fixed plate. The fixed plate is fixedly connected to the back of the pressing machine. The fixed plate has a reserved groove adapted to the rotating shaft inside. The end of the rotating shaft is connected to the inner wall of the reserved groove through a bearing. Limiting rods are vertically inserted above the fixed plate, and the top of the limiting rods is connected to a rotating rod. The two ends of the rotating shaft have slots at positions corresponding to the limiting rods.
[0011] Preferably, the outer wall of the limiting rod is provided with external threads, and the interior of the fixing plate is provided with a threaded groove that matches the limiting rod.
[0012] Preferably, a connecting sleeve is fitted on the front of the cylinder, and the inside of the connecting sleeve is connected to the cylinder by bolts. The front end of the connecting sleeve is fixedly connected to the back of the scraper.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. This device is equipped with a cylinder and a scraper. Before the pressing operation, the operator can start the cylinder, which will cause the scraper to move laterally above the pressing machine to push away the debris attached to the pressing machine. This eliminates the need for manual cleaning by the operator and effectively reduces the labor intensity of the operator.
[0015] 2. This device is equipped with a rotating shaft and a limiting rod. During use, the rotating shaft and the limiting rod work together to rotate the extension plate 90 degrees during transportation, so as to realize the storage operation of the extension plate and the cylinder. This can effectively reduce the footprint of the device and facilitate its transportation and packaging. 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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Reference Figure 1-5 A cardboard coating and pressing device includes a pressing machine 1. A hydraulic component 14 is installed above the pressing machine 1. The working principle of the pressing machine 1 and the hydraulic component 14 is existing technology and will not be described in detail here. An extension plate 2 is provided on the back of the pressing machine 1, and a connecting block 3 is connected to the side of the extension plate 2. A cylinder 4 is connected to the front of the connecting block 3, and a scraper 5 is distributed at the other end of the cylinder 4. The extension and retraction principle of the cylinder 4 is also existing technology and will not be described in detail here. By starting the cylinder 4, the scraper 5 can be moved laterally to achieve quick cleaning of the worktable above the pressing machine 1.
[0024] Furthermore, refer to Figure 1 and Figure 2 It can be seen that a collection frame 6 is provided on the front side of the pressing machine 1, and the opening length at the top of the collection frame 6 is greater than the horizontal length of the scraper 5. In use, the collection frame 6 can be used to collect debris. Because the top opening of the collection frame 6 is relatively long, it can achieve comprehensive collection of debris.
[0025] Furthermore, refer to Figure 1 and Figure 5 It can be seen that the front of the pressing machine platform 1 is connected to the tray 7, and the upper side of the tray 7 is symmetrically connected to the connecting strip 8. The bottom of the collection frame 6 is provided with a slide that matches the connecting strip 8. In use, the cooperation between the connecting strip 8 and the slide makes it easy for the staff to push down the full collection frame 6 for dumping.
[0026] Furthermore, refer to Figure 2 It can be seen that the side of the collection box 6 is provided with grooves, and the grooves are symmetrically distributed on the left and right ends of the collection box 6. The grooves facilitate the transfer and pushing of the collection box 6 by the staff.
[0027] Furthermore, refer to Figure 3 and Figure 4It can be seen that a rotating shaft 11 is inserted inside the extension plate 2, and both ends of the rotating shaft 11 are inserted into the fixed plate 10. The extension plate 2 can rotate together with the rotating shaft 11. The fixed plate 10 is fixedly connected to the back of the pressing machine table 1. The fixed plate 10 has a reserved groove adapted to the rotating shaft 11 inside. The end of the rotating shaft 11 is connected to the inner wall of the reserved groove through a bearing. Limiting rods 12 are vertically inserted on the top of the fixed plate 10, and the top of the limiting rods 12 is connected to a rotating rod 13. The two ends of the rotating shaft 11 have slots corresponding to the positions of the limiting rods 12. The rotating shaft 11 has two sets of slots inside, which can limit the rotating shaft 11 when it rotates 90 degrees, so that the staff can fold and store the extension plate 2.
[0028] Furthermore, refer to Figure 4 It can be seen that the outer wall of the limiting rod 12 is provided with external threads, and the inside of the fixing plate 10 is provided with a threaded groove that matches the limiting rod 12. Through the threaded engagement of the limiting rod 12 and the fixing plate 10, the limiting effect on the rotating shaft 11 can be guaranteed.
[0029] Furthermore, refer to Figure 3 It can be seen that the front of the cylinder 4 is fitted with a connecting sleeve 9, and the inside of the connecting sleeve 9 is connected to the cylinder 4 by bolts. The front end of the connecting sleeve 9 is fixedly connected to the back of the scraper 5. Through the cooperation of the connecting sleeve 9 and the bolts, it is easy for the staff to remove and replace the damaged scraper 5 in time.
[0030] Working Principle: When using this utility model, the operator can first move the device to a suitable position, and then rotate the rotating rod 13 in sequence, so that the limiting rod 12 is simultaneously rotated and pulled out from the slot inside the rotating shaft 11, thus releasing the limitation on the rotating shaft 11. Then, the operator can rotate the extension plate 2 ninety degrees so that it is parallel to the pressure plate inside the hydraulic component 14. After the rotation is completed, the operator can rotate the limiting rod 12 back into the rotating shaft 11 and lock it into another set of slots inside the rotating shaft 11, thereby limiting the extension plate 2. Then, the operator can start the cylinder 4, so that it pushes the scraper 5 to move laterally, so that the scraper 5 can push the debris stuck above the pressing machine table 1 into the collection frame 6 for collection. Then, the cylinder 4 drives the scraper 5 to reset. Then, the operator can place the multi-layer cardboard on the worktable of the pressing machine table 1, and then start the hydraulic component 14 to realize the pressing of the multi-layer cardboard. The above is the complete working principle of this utility model.
