Description

Technical Field

[0001] This utility model mainly relates to a coating device for printing paper separation adhesive, specifically a coating device for carbonless copy computer printing paper separation adhesive. Background Technology

[0002] Carbonless copy paper, also known as pressure-sensitive printing paper, consists of one top layer, multiple middle layers, and one bottom layer. It utilizes the principle of a chemical reaction between the color-developing agent layer in the microcapsules and the acidic clay in the developer layer. During printing, pressure is applied to the paper surface by the printing needles to achieve the color development effect. Commonly, there are 2 to 6 layers (each layer is commonly referred to as one copy). It is mainly used for continuous printing with dot matrix printers, but can also be used for handwriting, achieving the effect of copying multiple copies in one go.

[0003] Separating adhesive is a special water-soluble adhesive specifically designed for use with carbonless copy paper sets. When applied to the sides of the set, it exhibits good penetration and adhesion to the coatings of CF and CB sheets. Conversely, the uncoated sides (the other side) of CF and CB sheets, lacking a coating layer, show less penetration and weaker adhesion. Therefore, the sets of forms can be easily separated. In other words, the sheets automatically separate, and the top, middle, and bottom links of each sheet are automatically and firmly bonded together.

[0004] Currently, when applying the separating adhesive, operators mostly use brushes, which not only increases the physical labor of the operators but also takes a long time and is inefficient. When applying manually, the separating adhesive is also easy to stick to the operator's hands, causing discomfort. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a coating device for separating adhesive on carbonless copy computer printing paper. This invention uses a motor to power a lead screw, which in turn moves a connecting block back and forth, thereby moving the adhesive coating roller back and forth. This allows for the application of separating adhesive to the printing paper, reducing the manual labor required by operators and improving the efficiency of adhesive application. Simultaneously, under the action of a spring, a U-shaped pressure plate moves downwards, pressing and fixing the printing paper, thus improving the stability of the paper during adhesive application and ensuring the accuracy of the adhesive application.

[0006] To achieve the above objectives, this utility model employs the following technical solution:

[0007] A coating device for separating adhesive on carbonless copy paper includes a worktable. A U-shaped plate is installed on one side of the top surface of the worktable. A motor is installed in front of the U-shaped plate. A lead screw is installed at the rear end of the motor shaft. The rear end of the lead screw is rotatably connected to the U-shaped plate. A connecting block is threaded onto the lead screw. An L-shaped plate is installed on one side of the connecting block via a fixing rod. An adhesive roller is installed on the L-shaped plate. Two vertical plates, arranged front and back, are installed on the other side of the top surface of the worktable. A vertical rod is installed on the top surface of each vertical plate. A fixing block is slidably mounted on each vertical rod. A U-shaped pressure plate is installed between the two fixing blocks. A top plate is installed at the top of each vertical rod. A spring is installed between each top plate and the corresponding fixing block. A corresponding spring passes through the top of each vertical rod.

[0008] Furthermore, a storage box is installed on the top surface of the U-shaped plate, the storage box contains separating adhesive, and the storage box is connected to the adhesive roller via a hose.

[0009] Furthermore, a limiting rod is slidably installed on the connecting block, and both ends of the limiting rod are connected to the U-shaped plate.

[0010] Furthermore, two elastic telescopic rods distributed front and rear are installed on the L-shaped plate, and each elastic telescopic rod has a ball bearing rotatably installed at its bottom end.

[0011] Furthermore, a tie rod is installed on the top surface of the U-shaped pressure plate.

[0012] Furthermore, a baffle is installed at one end of each of the two vertical plates.

[0013] Furthermore, support legs are installed at all four corners of the bottom surface of the workbench.

[0014] Compared with the existing technology, the beneficial effects of this utility model are:

[0015] 1. This utility model uses a motor to provide power, which drives the lead screw to rotate, thereby causing the connecting block to move back and forth, which in turn drives the glue roller to move back and forth, thus enabling the application of separating adhesive to the printing paper, reducing the physical labor of operators and improving the efficiency of applying separating adhesive.

[0016] 2. Simultaneously, under the action of the spring force, the U-shaped pressure plate can be driven to move downward, thereby pressing and fixing the printing paper, which improves the stability of the printing paper when applying the separating adhesive, thus ensuring the accuracy of applying the separating adhesive.

[0022] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0023] like Figure 1-4 As shown, the coating device for the carbonless copy paper separating adhesive of this utility model includes a workbench 1. A U-shaped plate 2 is installed on one side of the top surface of the workbench 1. A motor 3 is installed in front of the U-shaped plate 2. A lead screw 4 is installed at the rear end of the motor 3's shaft. The rear end of the lead screw 4 is rotatably connected to the U-shaped plate 2. A connecting block 5 is threaded onto the lead screw 4. An L-shaped plate 7 is installed on one side of the connecting block 5 via a fixing rod 6. A coating roller 8 is installed on the L-shaped plate 7. Two vertical plates 9 distributed front to back are installed on the other side of the top surface of the workbench 1. A vertical rod 10 is installed on the top surface of each vertical plate 9. A fixing block 11 is slidably provided on each vertical rod 10. A U-shaped pressure plate 12 is installed between the two fixing blocks 11. A top plate 13 is installed at the top of each vertical rod 10. A spring 14 is installed between each top plate 13 and the corresponding fixing block 11. A corresponding spring 14 passes through the top of each vertical rod 10.

[0024] Specifically, a storage bin 15 is installed on the top surface of the U-shaped plate 2. The storage bin 15 contains separating adhesive and is connected to the coating roller 8 via a flexible hose. The storage bin 15 contains separating adhesive, which can be delivered to the coating roller 8 via the flexible hose, facilitating the application of separating adhesive onto the printing paper by the coating roller 8.

[0025] Specifically, a limiting rod 16 is slidably mounted on the connecting block 5, and both ends of the limiting rod 16 are connected to the U-shaped plate 2. The limiting rod 16 restricts the connecting block 5, ensuring the stability of the connecting block 5, thereby ensuring that the connecting block 6 can move stably along the lead screw 4.

[0026] Specifically, two elastic telescopic rods 17 are installed on the L-shaped plate 7, one in front of the other. Each elastic telescopic rod 17 has a ball bearing 18 rotatably mounted at its bottom end. Through the elastic force of the elastic telescopic rods 17, the ball bearing 18 can move up and down, thereby pressing and limiting the top of printing paper of different thicknesses, which facilitates the application of separation adhesive by the glue roller 8 to the printing paper.

[0027] Specifically, a pull rod 19 is installed on the top surface of the U-shaped pressure plate 12. By setting the pull rod 19, the U-shaped pressure plate 12 can be pulled upwards, thus facilitating the placement of printing paper.

[0028] Specifically, a baffle 20 is installed at one end of each of the two vertical plates 9. The baffle 20 restricts the end of the printing paper, further improving the limiting of the printing paper.

[0029] Specifically, support legs 21 are installed at each of the four corners of the bottom surface of the workbench 1. The support legs 21 provide support for the workbench 1.

[0030] Working principle:

[0031] When using this device, first pull the U-shaped pressure plate 12 upwards. The U-shaped pressure plate 12 drives the corresponding fixing block 11 to slide upwards along the vertical rod 10, and the spring 14 is compressed. Then, place the printing paper between the two vertical plates 9, and then release the U-shaped pressure plate 12. Under the elastic force of the spring 14, the fixing block 11 and the U-shaped pressure plate 12 move downwards. The U-shaped pressure plate 12 contacts the printing paper and presses and limits the printing paper. Then, the motor 3 works, and the motor 3 drives the lead screw 4 to rotate. The rotation of the lead screw 4 causes the connecting block 5 to move along the lead screw 4. The movement of the connecting block 5 drives the glue coating roller 8 to move. The glue coating roller 8 contacts one end of the printing paper and applies separation glue to one end of the printing paper, thereby improving the efficiency of applying separation glue, reducing the physical labor of the operator, and making it more convenient to apply separation glue to the printing paper.

This allows for the application of separating adhesive to the printing paper, reducing the manual labor required by operators and improving the efficiency of adhesive application. Simultaneously, under the action of a spring, a U-shaped pressure plate moves downward, thereby pressing and fixing the printing paper, improving the stability of the printing paper during adhesive application, and ensuring the accuracy of adhesive application.
