Description

Technical Field

[0001] This utility model relates to the field of paper coating technology, and more specifically, to a paper coating apparatus. Background Technology

[0002] Release paper is a paper-based material with a special coating. After the surface is coated, it can form a controllable adhesion and peel relationship with adhesives, resins or other materials under certain conditions (such as pressure and temperature).

[0003] Currently, silicone oil needs to be sequentially coated onto the surface of small pieces of release paper after production separation. The main purpose is to give the paper controllable release properties, enabling it to form a "peelable but residue-free" interface with pressure-sensitive adhesives (such as tapes, labels, etc.). Before coating, the release paper is first placed on a vacuum adsorption platform, which then firmly adsorbs it. After the release paper is fixed, a manual hand holds a wire rod and contacts it, then manually pours silicone oil onto the release paper. After pouring, the wire rod is manually pushed along the length of the release paper to complete the coating. However, this manual intervention involves many steps and is cumbersome, thus the automation level of the release paper coating process needs to be improved. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background art and to provide a paper coating device.

[0005] The technical solution adopted by this utility model to solve its technical problem is: A paper coating apparatus includes a vacuum adsorption platform and a mounting plate. The mounting plates are symmetrically fixed on the vacuum adsorption platform, and the mounting plates are provided with sliding grooves. Two mounting brackets are slidably fitted within the two grooves, and the mounting brackets are connected to a first lead screw assembly mounted on one of the mounting plates. The vertical lifting assembly is mounted on the mounting frame and is connected to a fixing plate; The wire rod is movably mounted on the fixed plate; The second lead screw assembly is located on the front side of the fixed plate, and a dispensing valve is provided on the second lead screw assembly; The feeding assembly is mounted on the mounting bracket and is connected to the dispensing valve via a hose.

[0006] Furthermore, the vertical lifting assembly includes a long screw, a slide rail, a limiting block (not labeled in the figure), a rotating component, and fastening screws. The long screw is threadedly connected to the mounting bracket; The slide rails that slide in conjunction with the fixed plate are symmetrically fixed on the mounting bracket, and limit blocks are provided at both ends of the slide rails; The rotating component is connected to one end of the long screw, and the other end of the long screw is rotatably connected to the fixed plate. The fastening screws are mounted on the mounting bracket and engage with the long screw.

[0007] Furthermore, the bar is symmetrically welded with insert rollers, and the insert rollers are provided with fixing bolts that are threadedly connected to the fixing plate. The fixing plate is provided with slots that correspond one-to-one with the insert rollers.

[0008] Furthermore, the feeding assembly includes a silicone oil tank and a metering pump. Both the silicone oil tank and the metering pump are fixed on the mounting bracket. The input end of the metering pump is connected to the silicone oil tank, and the output end of the metering pump is connected to the dispensing valve through a hose.

[0009] Furthermore, a collection box is placed on the front side of the vacuum adsorption platform, and a suction pump connected to the bottom area inside the collection box is installed on the collection box. The suction pump is connected to the recovery pool, and an inclined guide platform is installed on the bottom surface inside the collection box.

[0010] Furthermore, symmetrical support blocks are fixed inside the collection box, and filter screens that fit against the inner wall of the collection box are placed on the support blocks. Handles are symmetrically fixed on the filter screens.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. After the release paper is fixed by vacuum adsorption, this application only requires manual adjustment and limitation of the vertical position of the wire rod, and then the silicone oil dosing and wire rod coating process can be completed automatically. The manual intervention process is significantly reduced, thereby improving the automation level of the release paper coating process. 2. As the mounting frame moves continuously, the wire rod will push most of the remaining silicone oil into the collection box for storage. When the staff sees that the collection box is about to be full, they will control the suction pump through the PLC controller to transfer the silicone oil to the recycling pool. After subsequent impurity removal and deep processing, the silicone oil can be reused, which can significantly reduce the amount of silicone oil wasted. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments: like Figure 1 and Figure 2 As shown, a paper coating apparatus includes a vacuum adsorption platform 1 and a mounting plate 2. Mounting plates 2 are symmetrically fixed on vacuum adsorption platform 1, and mounting plates 2 are provided with sliding grooves 3; The two slide grooves 3 are slidably fitted with mounting brackets 4, and the mounting brackets 4 are connected to the first lead screw assembly 5 set on one of the mounting plates 2; The vertical lifting component 6 is mounted on the mounting frame 4, and the vertical lifting component 6 is connected to the fixing plate 7; The bar 8 is movably mounted on the fixed plate 7 (specifically, the bar 8 is symmetrically welded with insert rollers 81, the insert rollers 81 are provided with fixing bolts 82 that are threadedly connected to the fixed plate 7, and the fixed plate 7 is provided with slots that correspond one-to-one with the insert rollers 81, the slots are not shown in the figure). The second lead screw assembly 9 is located on the front side of the fixed plate 7, and a dispensing valve 10 is provided on the moving block of the second lead screw assembly 9. The feeding assembly 11 is mounted on the mounting bracket 4 and is connected to the dispensing valve 10 via a hose (the hose is shown in the figure but is not labeled). The dispensing valve 10 is existing technology and will not be improved. Its specific structure and principle are as follows: Composition: Valve body, valve core, solenoid coil, nozzle, return spring; principle: (1) Start-up phase: When the electromagnetic coil is energized, the magnetic force attracts the valve core upward, opening the flow channel; Metering pump 112 pushes silicone oil through the nozzle to form a stable liquid flow.

[0014] (2) Closure phase: After power is cut off, the spring force pushes the valve core to reset and fits tightly against the valve seat; Instantly cut off the flow path to prevent dripping.

[0015] Specific implementation of this utility model solution, such as Figure 2 As shown, the vertical lifting assembly 6 includes a long screw 61, a slide rail 62, a limit block (not shown in the figure), a rotating component 63, and a fastening screw 64. The long screw 61 is threadedly connected to the mounting bracket 4; The slide rail 62, which slides in cooperation with the fixed plate 7, is symmetrically fixed on the mounting bracket 4, and limit blocks are respectively provided at both ends of the slide rail 62; The rotating part 63 is connected to one end of the long screw 61 (the rotating part 63 is specifically either a knob or a handwheel, the figure shows a knob), and the other end of the long screw 61 is rotatably connected to the fixed plate 7 through a bearing; The fastening screw 64 is mounted on the mounting bracket 4 and engages with the long screw 61.

[0016] Specific implementation of this utility model solution, such as Figure 2 As shown, the feeding assembly 11 includes a silicone oil tank 111 and a metering pump 112. The silicone oil tank 111 and the metering pump 112 are both fixed on the mounting bracket 4. The input end of the metering pump 112 is connected to the silicone oil tank 111, and the output end of the metering pump 112 is connected to the dispensing valve 10 through a hose.

[0017] To achieve the recycling and reuse of excess silicone oil, further optimizations to the above embodiments are needed, such as... Figure 1 As shown, a collection box 12 with a height lower than its adsorption plane is placed on the front side of the vacuum adsorption platform 1. A suction pump 13 connected to the bottom area inside the collection box 12 is provided on the collection box 12. The suction pump 13 is connected to the recovery tank (the recovery tank is not shown in the figure). An inclined guide platform 121 is provided on the bottom surface inside the collection box 12. Based on this, in order to initially filter the collected silicone oil and reduce the probability of external impurities mixing into the collected silicone oil, the above-mentioned embodiment scheme is further optimized, such as... Figure 3 As shown, support blocks 122 are symmetrically fixed inside the collection box 12, and filter screens 123 that fit against the inner wall of the collection box 12 are placed on the support blocks 122. Handles 124 are symmetrically fixed on the filter screens 123.

[0018] It should be noted that the drive source in the first lead screw assembly 5, the drive source in the second lead screw assembly 9, the metering pump 112, and the suction pump 13 are all electrically connected to the PLC controller, which is not shown in the figure. The lead screw assembly is a prior art technology that can convert rotary motion into reciprocating linear motion.

[0019] The working process of this utility model: Initial mounting bracket 4 is located in the instruction manual. Figure 1 At the position shown, after the vacuum adsorption platform 1 has finished adsorbing the release paper (the vacuum adsorption platform 1 is existing technology and will not be improved; its working principle is common knowledge to those skilled in the art), the rotating part 63 is rotated. After the rotating part 63 moves, the rod 8 can be moved downward. When the rod 8 comes into contact with the surface of the release paper, the fastening screw 64 is used to limit the long screw 61 to prevent the subsequent rotation of the long screw 61 from causing the rod 8 to move vertically. After the adjustment of the wire rod 8 is completed, the metering pump 112 is controlled by the PLC controller to inject silicone oil into the dispensing valve 10 and discharge it. At the same time, the dispensing valve 10 can move horizontally at a constant speed under the operation of the second lead screw assembly 9 to expand the dispensing area. It should be noted that the motion range of the dispensing valve 10 can be preset. After the silicone oil is automatically dispensed onto the release paper, the first lead screw assembly 5 is controlled by the PLC controller to operate. The operation of the first lead screw assembly 5 can realize the horizontal linear movement of the mounting frame 4 along the slide 3, and then the coating process on the surface of the release paper can be automatically completed. As the mounting frame 4 continues to move, the wire rod 8 will push most of the remaining silicone oil into the collection box 12 for storage. When the staff sees that the collection box 12 is about to be full, they will control the suction pump 13 through the PLC controller to transfer the silicone oil to the recycling pool. After subsequent impurity removal and deep processing, the silicone oil can be reused. This can significantly reduce the amount of silicone oil wasted. (In addition, after a period of coating, the residual silicone oil on the vacuum adsorption platform needs to be effectively cleaned to ensure the subsequent use effect of the vacuum adsorption platform.) When it is necessary to replace or maintain the bar 8, first remove the fixing bolt 82, and then the bar 8 can be quickly removed. After maintenance, the bar 8 can be reinstalled by accurately positioning it in the slot and the insert roller 81. Then, the mounting bracket 4 will automatically return to the position specified in the instruction manual via the first lead screw assembly 5. Figure 1 The next round of release paper coating can be carried out at the position shown.

[0020] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
