Description

Technical Field

[0001] This utility model relates to the field of thermal paper technology, and more specifically, to a thermal paper output guiding structure. Background Technology

[0002] Thermal paper, also known as thermal fax paper, thermal recording paper, and thermal copy paper, is made by coating a regular paper base with microparticle powder. The powder consists of colorless dyes such as phenol or other acidic substances, separated by a thin film. When heated, the film melts, and the powder mixes to produce a color reaction. A guide structure is needed to assist in the unpacking of thermal paper.

[0003] Patent application number 202122298372.5 discloses a novel environmentally friendly thermal paper output guiding structure, comprising two circular plates. A rod is fixedly connected to one side of each circular plate, and multiple grooves are provided on one side of each circular plate. These grooves are evenly arranged along the circumference of the circular plates, with the center as the reference point. A slider is slidably connected within each groove, and a spring is provided within each groove. Each spring is fixedly connected between the slider and the bottom of the groove. A circular rod is fixedly connected to one side of each slider, and a rotating roller is sleeved on the outer wall of each circular rod. This invention uses two circular plates with rotating rollers to install the thermal paper roll in a thermal printer. During installation, it protects the thermal paper roll from rubbing against components inside the thermal printer, preventing damage. During printing, each rotating roller moves against the outer wall of the thermal paper roll as the thickness of the thermal paper roll changes, ensuring that even when the thermal paper roll becomes thinner, the outermost layer of paper is still smoothly and slowly pulled out by the rolling of the rotating rollers.

[0004] Regarding the aforementioned technologies, during printing, each rotating roller can move against the outer wall of the thermal paper roll as the thickness of the thermal paper roll changes. This ensures that even when the thermal paper roll becomes thinner, the outermost paper roll can still be smoothly and slowly pulled out by the rolling of the rotating rollers. The slider, pulled by a spring, drives the rotating rollers on the same side to move, thus keeping the rotating rollers in constant contact with the outer wall of the thermal paper roll for stable subsequent output. However, when the thermal paper rolls on the same side are not installed, they are close to each other. When installing the thermal paper roll, the rotating rollers need to be manually moved and pushed apart to facilitate the insertion of the insert rods mounted on the side wall of the circular plate into the thermal paper roll. Due to the coordination of multiple rotating rollers, it is difficult for the operator to push them simultaneously at one time, which may affect the installation efficiency of the thermal paper roll. Utility Model Content

[0005] To solve the above problems, this utility model provides a thermal paper output guiding structure, which adopts the following technical solution:

[0006] A thermal paper output guide structure includes a housing, inside which are two symmetrically distributed mounting discs. A post is rotatably mounted on one side of each mounting disc, and anti-slip sleeves are fitted onto the sidewalls of both posts. Limiting blocks are fixedly mounted on the inner walls of both sides of the housing. Limiting grooves matching the limiting blocks on the opposite sides of the two mounting discs are provided. Arc-shaped plates are fixedly mounted on the sidewalls of each mounting disc, and mounting blocks are fixedly mounted on the side of each arc-shaped plate away from the mounting disc. Two symmetrically distributed rotating rollers are rotatably mounted on the opposite sides of each mounting block.

[0007] Connecting blocks are slidably installed on the inner walls of both sides of the housing. Support rods are provided on opposite sides of the two connecting blocks. Tension sensors are provided between the two support rods. Telescopic components are provided between the bottom of the two connecting blocks and the inner wall of the bottom of the housing. A first support roller is rotatably installed inside the housing. Two second support rollers are rotatably installed inside the housing and are symmetrically distributed. The two second support rollers are located above the first support roller.

[0008] By adopting the above technical solution, when using this equipment, the operator removes the installation plate from the housing, then places the insert post installed on one side of the installation plate inside the thermal paper roll. The insert post has an anti-slip sleeve on its side wall, which helps increase the stability of the insertion of the insert post and the thermal paper roll, thereby improving the stability of the assembly of the thermal paper roll and the two installation plates. After the thermal paper roll is assembled, the operator places the installation plate inside the housing, allowing the limiting groove on one side of the installation plate to engage with the limiting block installed on the inner wall of the housing, thus fixing the installation plate and enabling quick installation of the thermal paper roll. After the thermal paper roll is installed, the operator... The operator passes the end of the thermal paper through two rotating rollers, which clamp the sides of the thermal paper to guide it and facilitate stable output. The paper then passes sequentially through a tension sensor, a first support roller, and a second support roller. The tension sensor detects the tension of the thermal paper during output, while the first and second support rollers not only support the paper but also guide it. A telescopic assembly is located between the tension sensor and the inner wall of the housing's bottom, allowing for height adjustment of the tension sensor and, consequently, the tension of the thermal paper during output, thus maintaining its stability.

[0009] Furthermore, the telescopic assembly includes a mounting plate disposed below the two connecting blocks. Two symmetrically distributed telescopic rods are fixedly installed on the inner wall of the bottom end of the housing. The ends of the two telescopic rods are fixedly connected to the bottom end of the mounting plate. Two symmetrically distributed pillars are fixedly installed on the top end of the mounting plate. Each pillar has a movable groove at its top. A support rod is slidably installed in each of the two movable grooves. The top ends of the two support rods are fixedly connected to the bottom end of the connecting block on the same side. A spring is fixedly connected between the bottom ends of the two support rods and the inner wall of the bottom end of the movable groove on the same side.

[0010] By adopting the above technical solution, the mounting plate, support column, support rod, connecting block, support rod, and tension sensor are driven to rise synchronously by the telescopic rod. The tension sensor detects the tension when the thermal paper is being pushed out. The support rod and tension sensor push the thermal paper to adjust the tension when the thermal paper is being pushed out. When the support rod pushes the thermal paper, the connecting block pushes the support rod on the same side to slide in the movable groove on the same side. The support rod pushes the spring on the same side to contract. The spring gives the support rod and connecting block on the same side a rebound force, achieving a buffering effect and helping to prevent the thermal paper from being damaged due to excessive pushing force.

[0011] Furthermore, each of the two support columns has two symmetrically distributed sliding grooves on its sidewalls. The two sliding grooves on the same side are connected to the movable groove on the same side. A slider is slidably installed in each sliding groove. The opposite side of the two sliders on the same side is fixedly connected to the lower section of the support column on the same side.

[0012] By adopting the above technical solution, when the support rod slides in the same side movable groove, the support rod, along with the slider, slides in the same side sliding groove. The cooperation between the slider and the sliding groove helps to maintain the stability of the support rod's sliding and helps to prevent the support rod from leaving the same side movable groove.

[0013] Furthermore, positioning rods are fixedly installed on opposite sides of the two sliders on the same side, and positioning grooves matching the positioning rods on the same side are opened on the lower section side wall of the support rod.

[0014] By adopting the above technical solution, the slider and the support rod are fixed together by fasteners of existing technology. When installing the slider, the worker places the slider in the groove opened in the side wall of the support rod, so that the positioning rod installed in the side wall of the slider engages with the positioning groove opened in the side wall of the support rod. The engagement of the positioning rod and the positioning groove plays the role of positioning the slider, which facilitates subsequent fixing.

[0015] Furthermore, each of the two curved plates has a plug fixedly installed on the side away from the mounting block on the same side, and the sidewalls of the two mounting plates have slots that match the plugs on the same side.

[0016] By adopting the above technical solution, the curved plate and the mounting plate on the same side are fixed together by fasteners of existing technology. When it is necessary to install the curved plate and the mounting block, the worker places the curved plate on the side wall of the mounting plate so that the plug installed on one side of the curved plate engages with the slot opened on the side wall of the mounting plate. The engagement of the plug and the slot serves to position the curved plate, which is convenient for subsequent fixing.

[0017] Furthermore, two symmetrically distributed rubber rods are fixedly installed on the inner walls of the top of each of the two limiting grooves, and holes matching the rubber rods on the same side are opened at the top of the two limiting blocks.

[0018] By adopting the above technical solution, when the mounting plate engages with the limiting block installed on the inner wall of the housing, a rubber rod is provided in the limiting groove. The rubber rod is inserted into the hole opened at the top of the limiting block on the same side. The engagement of the rubber rod and the hole helps to increase the friction between the mounting plate and the limiting block on the same side, thereby improving the stability of the mounting plate installation.

[0019] Furthermore, two symmetrically distributed locking blocks are fixedly installed on the inner walls of both sides of the housing, and the opposite sides of the two mounting plates are provided with locking slots that match the locking blocks on the same side.

[0020] By adopting the above technical solution, there are locking blocks on both sides of the shell. When the mounting plate engages with the limiting block installed on the inner wall of the shell, the slot opened on one side of the mounting plate engages with the locking block installed on the inner wall of the shell, which plays the role of positioning the mounting plate.

[0021] In summary, this utility model has the following beneficial technical effects:

[0022] (1) In this utility model, by setting two mounting plates, there are insert posts on one side of the two mounting plates opposite each other. The insert posts are placed inside the thermal paper roll. By cooperating with the two mounting plates, the thermal paper roll can be clamped and fixed. Then, the operator places the mounting plate inside the housing. The limiting block and the card block and the limiting groove and card slot opened on the side wall of the mounting plate are engaged to quickly install the thermal paper roll.

[0023] (2) In this utility model, the two mounting disc sidewalls are set with rotating rollers to restrict the two sides of the thermal paper and achieve the guiding effect. In addition, through the cooperation of the support rod, the first support roller and the second support roller, it not only supports the thermal paper, but also guides it, which helps to maintain the stability of the thermal paper output.

[0024] (3) In this utility model, the tension sensor is set to detect the tension when the thermal paper is exported. A telescopic component is provided between the tension sensor and the housing. Through the cooperation of the telescopic rod, mounting plate, support column, support rod and spring, the support rod and tension sensor can be driven to rise and fall. The support rod and tension sensor push the thermal paper to remove the tension when the thermal paper is exported, which helps to maintain the stability of the thermal paper export.

[0037] The following is in conjunction with the appendix Figures 1-7 The present invention will be described in further detail below.

[0038] Please see Figures 1-7 A thermal paper output guide structure includes a housing 1. Inside the housing 1 are two symmetrically distributed mounting discs 2. Inserts 3 are rotatably mounted on opposite sides of each mounting disc 2. Anti-slip sleeves are fitted onto the side walls of each insert 3. Limiting blocks 20 are fixedly mounted on the inner walls of both sides of the housing 1. Limiting grooves 22 matching the limiting blocks 20 on opposite sides of the two mounting discs 2 are provided. Arc-shaped plates 18 are fixedly mounted on the side walls of each mounting disc 2. Mounting blocks 4 are fixedly mounted on the side of each arc-shaped plate 18 away from the mounting disc 2 on the same side. Two symmetrically distributed rotating rollers 5 are rotatably mounted on opposite sides of each mounting block 4. Two symmetrically distributed rubber rods are fixedly mounted on the inner walls of the tops of each limiting groove 22. Holes matching the rubber rods on the tops of each limiting block 20 are provided. Two symmetrically distributed locking blocks 21 are fixedly mounted on the inner walls of both sides of the housing 1. Locking grooves matching the locking blocks 21 on opposite sides of each mounting disc 2 are provided.

[0039] When using the device, the operator removes the mounting plate 2 from the housing 1. Then, the insert 3, installed on one side of the mounting plate 2, is placed inside the thermal paper roll. The side wall of the insert 3 has an anti-slip sleeve, which helps increase the stability of the insertion between the insert 3 and the thermal paper roll, thereby improving the stability of the assembly of the thermal paper roll and the two mounting plates 2. After the thermal paper roll is assembled, the operator places the mounting plate 2 back into the housing 1, causing the limiting groove 22 on one side of the mounting plate 2 to engage with the limiting block 20 installed on the inner wall of the housing 1. This secures the mounting plate 2 and facilitates the rapid installation of the thermal paper roll. When the mounting plate 2 engages with the limiting block 20 installed on the inner wall of the housing 1, a rubber rod is provided in the limiting groove 22. The rubber rod is inserted into the hole opened at the top of the limiting block 20 on the same side. The engagement of the rubber rod and the hole helps to increase the friction between the mounting plate 2 and the limiting block 20 on the same side, thereby improving the stability of the mounting plate 2. There are locking blocks 21 on both sides of the housing 1. When the mounting plate 2 engages with the limiting block 20 installed on the inner wall of the housing 1, the locking groove opened on one side of the mounting plate 2 engages with the locking block 21 installed on the inner wall of the housing 1, which serves to position the mounting plate 2.

[0040] Connecting blocks 6 are slidably installed on the inner walls of both sides of the housing 1. Support rods 7 are provided on the opposite side of the two connecting blocks 6. Tension sensors 8 are provided between the two support rods 7. Telescopic components are provided between the bottom of the two connecting blocks 6 and the inner wall of the bottom end of the housing 1. A first support roller 9 is rotatably installed inside the housing 1. Two second support rollers 10 are rotatably installed inside the housing 1 in a symmetrical arrangement. The two second support rollers 10 are located above the first support roller 9.

[0041] The telescopic assembly includes a mounting plate 12 located below the two connecting blocks 6. Two symmetrically distributed telescopic rods 11 are fixedly installed on the inner wall of the bottom end of the housing 1. The ends of the two telescopic rods 11 are fixedly connected to the bottom end of the mounting plate 12. Two symmetrically distributed support columns 13 are fixedly installed on the top end of the mounting plate 12. Each of the two support columns 13 has a movable groove 16 at its top end. A support rod 23 is slidably installed in each of the two movable grooves 16. The top ends of the two support rods 23 are fixedly connected to the bottom end of the connecting block 6 on the same side. A spring 17 is fixedly connected between the bottom end of the two support rods 23 and the inner wall of the bottom end of the movable groove 16 on the same side.

[0042] After the thermal paper roll is installed, the worker passes the end of the thermal paper through two rotating rollers 5. The rotating rollers 5 clamp the two sides of the thermal paper, achieving a guiding effect and facilitating the stable output of the thermal paper. Then, it passes through the tension sensor 8, the first support roller 9, and the second support roller 10 in sequence. The tension sensor 8 detects the tension of the thermal paper during output. The first support roller 9 and the second support roller 10 not only support the thermal paper but also guide it. The mounting plate 12, the support column 13, the support rod 23, the connecting block 6, the support rod 7, and the tension sensor 8 rise synchronously through the telescopic rod 11. The tension sensor 8 detects the tension of the thermal paper during output, and the support rod 7 and the tension sensor 8 push the thermal paper to adjust the tension during output. When the support rod 7 pushes the thermal paper, the connecting block 6 pushes the support rod 23 on the same side to slide in the movable groove 16 on the same side. The support rod 23 pushes the spring 17 on the same side to contract. The spring 17 provides a rebound force to the support rod 23 and the connecting block 6 on the same side, achieving a buffering effect and helping to prevent the thermal paper from being damaged by excessive pushing force.

[0043] Two symmetrically distributed sliding grooves 14 are provided on the side walls of the two support columns 13. The two sliding grooves 14 on the same side are connected to the movable groove 16 on the same side. A slider 15 is slidably installed in each sliding groove 14. The opposite side of the two sliders 15 on the same side is fixedly connected to the lower side wall of the support rod 23 on the same side. When the support rod 23 slides in the movable groove 16 on the same side, the support rod 23 carries the slider 15 in the sliding groove 14 on the same side. The cooperation between the slider 15 and the sliding groove 14 helps to maintain the stability of the sliding of the support rod 23 and helps to prevent the support rod 23 from disengaging from the movable groove 16 on the same side.

[0044] Positioning rods are fixedly installed on opposite sides of the two sliders 15 on the same side. The lower side wall of the support rod 23 has a positioning groove that matches the positioning rod on the same side. The sliders 15 and the support rod 23 are fixed together by fasteners of existing technology. When installing the sliders 15, the workers place the sliders 15 into the grooves 14 opened on the side wall of the support rod 13, so that the positioning rods installed on the side wall of the sliders 15 engage with the positioning grooves opened on the side wall of the support rod 23. The engagement of the positioning rods and the positioning grooves serves to position the sliders 15, which facilitates subsequent fixing.

[0045] Two curved plates 18 are each fixedly mounted with inserts 19 on the side away from the mounting block 4. The side walls of the two mounting discs 2 are provided with slots that match the inserts 19 on the same side. The curved plates 18 and the mounting discs 2 on the same side are fixed together by fasteners of the prior art. When it is necessary to install the curved plates 18 and the mounting block 4, the operator places the curved plates 18 on the side wall of the mounting disc 2 so that the inserts 19 installed on one side of the curved plates 18 engage with the slots provided on the side wall of the mounting disc 2. The engagement of the inserts 19 and the slots serves to position the curved plates 18, which is convenient for subsequent fixing.

[0046] The implementation principle of this utility model embodiment is as follows: When using the device, the operator removes the installation plate 2 from the housing 1, and then places the insertion post 3 installed on one side of the installation plate 2 inside the thermal paper roll. The side wall of the insertion post 3 is provided with an anti-slip sleeve, which helps to increase the stability of the insertion post 3 and the thermal paper roll, thereby improving the stability of the thermal paper roll and the two installation plates 2. After the thermal paper roll is assembled, the operator places the installation plate 2 inside the housing 1, so that the limiting groove 22 opened on one side of the installation plate 2 engages with the limiting block 20 installed on the inner wall of the housing 1, which can fix the installation plate 2, thereby achieving the function of quickly installing the thermal paper roll. When the thermal paper roll is installed... Then, the staff passes the end of the thermal paper through two rotating rollers 5. The rotating rollers 5 clamp the two sides of the thermal paper to achieve a guiding effect, which facilitates the stable output of the thermal paper. Then, it passes through the tension sensor 8, the first support roller 9 and the second support roller 10 in sequence. The tension sensor 8 can detect the tension of the thermal paper when it is output. The first support roller 9 and the second support roller 10 not only support the thermal paper but also guide it. There is a telescopic component between the tension sensor 8 and the inner wall of the bottom of the housing 1, which can adjust the height of the tension sensor 8, thereby adjusting the tension of the thermal paper when it is output, which helps to maintain the stability of the thermal paper during output.

[0047] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be included within the scope of protection of this utility model.
