Description

Technical Field

[0001] This utility model mainly relates to the technical field of heat drying equipment for carbonless copy paper, specifically a heat drying equipment for producing carbonless copy paper. Background Technology

[0002] Carbonless copy paper is a type of invisible copy paper that can directly copy and develop colors. It is mainly used for multi-part forms, invoices, continuous financial documents, and general business financial documents. During the production of carbonless copy paper, adhesive is applied to both sides. After the adhesive is applied, it needs to be dried using heat drying equipment. Only after drying can it be rolled up and stored.

[0003] The patented technology, with publication number CN217737801U, discloses a hot drying oven for the production of carbonless copy paper. This technology has the advantages of preventing the carbonless copy paper wrapped around the outside of the winding drum from becoming loose and facilitating the disassembly and assembly of the winding drum. It solves the problem that since the dried carbonless copy paper is generally directly wrapped around the outside of the winding drum, if the carbonless copy paper wrapped around the outside of the winding drum is not tied up in time when the winding is nearing the end, it is easy to become loose. At the same time, the existing winding drum is inconvenient to disassemble and assemble, which affects its use.

[0004] However, this patent still has shortcomings. Although it can heat-dry carbonless copy paper, as can be seen from the attached drawings, the patent uses hot air to dry the copy paper. Since hot air is lightweight, it tends to accumulate at the top of the box, resulting in poor drying effect and wasting resources. At the same time, the patent requires the copy paper to be rolled up during use, which increases the operation time and reduces the drying efficiency, thus causing inconvenience to users. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a heat-drying device for producing carbonless copy paper. Through a transmission device, a sliding block moves horizontally along a slide rail, thereby moving a placement plate and, consequently, the copy paper. This allows the copy paper to sequentially contact multiple heating rollers, which then heat the glued end of the copy paper, improving the drying effect. Simultaneously, the height of the heating rollers can be adjusted by a threaded rod, enabling the drying of copy paper of different thicknesses, enhancing the device's practicality. Furthermore, the spring force ensures that the heating rollers remain in contact with the copy paper, guaranteeing optimal drying performance.

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

[0009] Furthermore, a U-shaped baffle is installed on the front side of the top surface of the placement plate, and a fastening device is installed on the top surface of the U-shaped baffle.

[0023] 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.

[0024] like Figure 1-4 As shown, the present invention discloses a heat-drying device for producing carbonless copy paper, comprising a workbench 1, an L-shaped plate 2 mounted on the rear side of the top surface of the workbench 1, a threaded rod 3 mounted on the L-shaped plate 2, a horizontal plate 4 rotatably mounted on the bottom end of the threaded rod 3, a connecting plate 6 mounted on the bottom surface of the horizontal plate 4 via a first spring 5, two vertical plates 7 distributed front to back mounted on the bottom surface of the connecting plate 6, several evenly distributed heating rollers 8 mounted between the two vertical plates 7, each heating roller 8 containing an electric heating wire, two slide rails 9 distributed front to back mounted on the front side of the top surface of the workbench 1, sliding blocks 10 slidably mounted on the two slide rails 9, a placement plate 11 mounted on the top surface of the sliding block 10, the top surface of the placement plate 11 capable of holding copy paper, and a transmission device mounted on the top surface of the workbench 1, the transmission device being connected to the sliding block 10.

[0025] Specifically, the transmission device includes a motor 12, which is mounted on one side of the top surface of the workbench 1. A lead screw 13 is mounted on one end of the motor 12's shaft, and the lead screw 13 passes through and is threadedly engaged with the sliding block 10. A fixing plate 14 is mounted on the other side of the top surface of the workbench 1, and the lead screw 13 is rotatably connected to the fixing plate 14. When the motor 12 operates, it drives the lead screw 13 to rotate. The rotation of the lead screw 13 causes the sliding block 10 to slide along the slide rail 9, thereby moving the placement plate 11.

[0026] Specifically, a U-shaped baffle 15 is installed on the front side of the top of the placement plate 11, and a fastening device is installed on the top surface of the U-shaped baffle 15. The U-shaped baffle 15 has a limiting effect on the carbon paper placed on the placement plate 11, and together with the mechanism, it ensures the stability of the carbon paper.

[0027] Specifically, the fastening device includes two vertical rods 16 distributed laterally. The two vertical rods 16 are mounted on the top surface of the U-shaped baffle 15. A support plate 17 is mounted on the top of the two vertical rods 16. Two limiting rods 18 distributed laterally are slidably mounted on the support plate 17. A pressure plate 19 is mounted on the bottom end of each limiting rod 18. A second spring 20 is fitted around the outer periphery of the bottom end of each limiting rod 18. The top end of each second spring 20 is connected to the support plate 17, and the bottom end of each second spring 20 is connected to the pressure plate 19. Through the elastic force of the second springs 20, the pressure plate 19 can be driven to move downwards, thereby pressing and limiting the top surface of the carbon paper.

[0028] Specifically, a pull block 21 is installed between the top ends of the two limiting rods 18. By setting the pull block 21, the limiting rods 18 can be pulled upward, thereby causing the pressure plate 19 to move upward, making it easier to place the box and take out the carbon paper.

[0029] Specifically, each of the four corners of the bottom surface of the workbench 1 is equipped with a support leg 22, and the bottom surface of each support leg 22 is rough. The support leg 22 provides support for the workbench 1.

[0030] Specifically, two levers 23 are installed on the top surface of the horizontal plate 4, each lever 23 passing through the L-shaped plate 2 and capable of sliding up and down along the L-shaped plate 2. The levers 23 restrict the horizontal plate 4, ensuring that the horizontal plate 4 can move stably up and down in the vertical direction.

[0031] Working principle:

[0032] When using this device, carbonless copy paper is first placed on the placement plate 11. Then, the fastening device presses and limits the copy paper on the placement plate 11. The heating roller 8 then operates, generating heat. The transmission device then operates, driving the sliding block 10 to move along the slide rail 9, which in turn moves the placement plate 11. The movement of the placement plate 11 moves the copy paper, and the glued end of the copy paper contacts the heating roller 8. Under the elastic force of the first spring 5, the copy paper can push the heating roller 8 upward, thus ensuring that the copy paper can make good contact with the heating roller 8. After being heated by one heating roller 8, and then by several subsequent heating rollers 8, the heating effect is improved. After the copy paper passes through the heating roller 8, it can be easily removed from the placement plate 11, and a new copy paper can be placed for heating, thus improving the heating efficiency.

[0033] This solution also includes a controller, the location of which is set by the staff according to the actual situation during operation. The controller is used to control the electrical components used in this solution. The controller is one of an Intel processor, AMD processor, PLC controller, ARM processor, or microcontroller. It is used in conjunction with a motherboard, memory module, storage medium, and power supply, which is AC power or lithium battery. When a display screen is provided, a display card is also provided. For the operating principle of the controller, please refer to "Automatic Control Principles", "Microcontroller Principles and Application Simulation Cases", and "Sensor Principles and Applications" published by Tsinghua University Press. Other books in this field can also be consulted. Other automation control and electrical components not mentioned are knowledge well known to those skilled in the art and will not be described in detail here.

[0034] This invention utilizes a transmission device to allow the sliding block to move horizontally along the slide rail, thereby moving the placement plate and then the carbon paper. This allows the carbon paper to sequentially contact multiple heating rollers, which in turn heat the glued end of the carbon paper, improving the heating effect. Simultaneously, the height of the heating rollers can be adjusted by the screw rod, enabling the heating of carbon paper of different thicknesses, thus enhancing the practicality of the device. Under the action of spring force, the heating rollers are always kept in contact with the carbon paper, ensuring the heating effect.
