Description

Technical Field

[0001] This utility model belongs to the technical field of paper flattening and pressing in archives, specifically relating to an auxiliary device for paper flattening and pressing during archive scanning. Background Technology

[0002] During storage and use, archival paper may develop wrinkles, curls, or unevenness due to various reasons (such as humidity, improper mechanical processing, etc.). This not only affects the appearance quality of the paper but also has an adverse effect on processes such as scanning archival paper. Therefore, a paper flattening and pressing auxiliary device is needed to achieve the flattening effect of the paper.

[0003] Problems with existing technology:

[0004] Most existing paper flattening and pressing devices simply flatten archival paper by pressing it down directly with a pressure plate. When the surface of the archival paper has many wrinkles, it takes a long time to ensure the flattening effect, which greatly reduces the flattening efficiency of the archival paper and makes it difficult for staff to complete the archival management work smoothly. Utility Model Content

[0005] The purpose of this invention is to provide an auxiliary device for flattening and pressing paper during document scanning. This device can solve the problem that most existing paper flattening and pressing devices simply press down on the document paper directly with a pressure plate. When the document paper has many wrinkles, it takes a long time to ensure the flattening effect, which greatly reduces the efficiency of flattening the document paper and makes it difficult for staff to complete document management work smoothly.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] An auxiliary device for flattening and pressing paper during document scanning includes a base. Two fixing plates are fixedly connected to the upper end of the base. An electric telescopic rod body is fixedly installed on the front fixing plate. A push-pull plate is fixedly connected to the rear end of the electric telescopic rod body. A paper placement plate is fixedly connected to the upper end of the push-pull plate. A paper fixing component is provided on the left side of the paper placement plate. The lower end of the paper fixing component engages with a meshing toothed plate.

[0008] A fixed frame is fixedly connected to the upper rear side of the base. An electric telescopic rod body two is fixedly installed on the left end of the fixed frame. The right end of the electric telescopic rod body two is fixedly connected to the paper leveling component. The upper side of the paper leveling component is slidably connected to two limiting rods one. The left and right ends of the two limiting rods one are respectively fixedly connected to the left and right sides inside the fixed frame.

[0009] An L-shaped plate is fixedly connected to the left end of the meshing toothed plate. The lower end of the L-shaped plate is fixedly connected to the base. Two support sliders are fixedly connected to the lower end of the paper placement plate. The two support sliders are slidably connected to two limiting rods. The front and rear ends of the two limiting rods are fixedly connected to the relatively close ends of the two fixed plates.

[0010] The paper fixing assembly includes an L-shaped frame, the lower end of which is fixedly connected to the upper end of the paper placement plate, and the left end of the L-shaped frame is fixedly connected to two fixing plates, which are respectively movably connected to the upper and lower sides of the threaded rod.

[0011] The lower end of the threaded rod is fixedly connected to a meshing gear, which meshes with a meshing tooth plate, and the threaded rod is threadedly connected to a connecting plate with a threaded hole inside.

[0012] The connecting plate is slidably connected to two limiting rods three through two limiting holes inside it, and the upper and lower ends of the two limiting rods three are fixedly connected to the relatively close ends of the two fixing plates two.

[0013] The connecting plate is slidably connected to two T-shaped guide rods through two guide holes on its right side. The lower ends of the two T-shaped guide rods are fixedly connected to the pressure plate. The lower end of the pressure plate is provided with an anti-slip pad. Springs are sleeved on the two T-shaped guide rods. The lower ends of the two springs are fixedly connected to the pressure plate, and the upper ends of the two springs are fixedly connected to the connecting plate.

[0014] The paper flattening component includes a T-shaped plate. The left end of the T-shaped plate is fixedly connected to the right end of the main body of the electric telescopic rod. The T-shaped plate is slidably connected to two limiting rods through limiting holes opened at both its front and rear ends.

[0015] The lower end of the T-shaped plate is fixedly installed with an electric push rod body, and the lower end of the electric push rod body is fixedly connected to the upper end of the mounting plate. The lower end of the mounting plate is provided with an air duct, a heating pressure roller, and a flat scraper.

[0016] The front end of the air duct is fixedly connected to one end of the connecting conduit, and the other end of the connecting conduit is fixedly connected to the front end of the fan body. The fan body is fixedly installed on the upper end of the mounting plate.

[0017] The upper end of the mounting plate is fixedly connected to four T-shaped guide rods, and the four T-shaped guide rods are slidably connected to a T-shaped plate with four guide holes inside the lower end.

[0018] The technical effects achieved by this utility model are as follows:

[0019] This invention utilizes the interaction of an electric telescopic rod body, a push-pull plate, a support slider, and a limiting rod to move a paper placement plate backward, thereby moving the paper placed on it below the paper leveling component. During this backward movement, the meshing toothed plate and gears cause a threaded rod to rotate. This rotation, combined with the limiting rod, connecting plate, T-shaped guide rod, and spring, moves a pressure plate downward, automatically securing one end of the paper and ensuring proper paper leveling. The stability of the paper during the flattening process is ensured by the downward movement of the mounting plate driven by the electric push rod, which in turn moves the heating roller and the flattening scraper downward to the top of the paper. Then, with the cooperation of the electric telescopic rod, T-shaped plate, T-shaped guide rod, and mounting plate, the heating roller and flattening scraper move to the right, thereby achieving the flattening and heating-setting effect of the paper. Furthermore, the cooling process of the heated and set paper is quickly achieved through the cooperation of the fan, connecting duct, and air duct, improving the flattening and setting effect of the device.

[0029] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0030] like Figure 1-7 As shown, a paper flattening and pressing auxiliary device for document scanning includes a base 1. Two fixing plates 13 are fixedly connected to the upper end of the base 1. An electric telescopic rod body 2 is fixedly installed on the front fixing plate 13. A push-pull plate 14 is fixedly connected to the rear end of the electric telescopic rod body 2. A paper placement plate 3 is fixedly connected to the upper end of the push-pull plate 14. A paper fixing component 5 is provided on the left side of the paper placement plate 3. The lower end of the paper fixing component 5 engages with a meshing toothed plate 6. The electric telescopic rod body 2 drives the push-pull plate 14 to move backward, thereby driving the paper placement plate 3 to move backward to the lower side of the paper flattening component 8. During the process of driving the paper placement plate 3 to move backward, with the cooperation of the meshing toothed plate 6 and the paper fixing component 5, the paper to be flattened placed on the paper placement plate 3 can be fixed at one end, ensuring the stability of the paper during the subsequent paper flattening process.

[0031] A fixed frame 10 is fixedly connected to the upper rear side of the base 1. An electric telescopic rod body 2 9 is fixedly installed on the left end of the fixed frame 10. The right end of the electric telescopic rod body 2 9 is fixedly connected to the paper leveling component 8. The upper side of the paper leveling component 8 is slidably connected to two limiting rods 11. The left and right ends of the two limiting rods 11 are fixedly connected to the left and right sides inside the fixed frame 10, respectively. The limiting rods 11 can increase the stability of the paper leveling component 8 during movement. The cooperation between the electric telescopic rod body 2 9 and the paper leveling component 8 can achieve the leveling process of the paper placed on the paper placement plate 3.

[0032] Furthermore, an L-shaped plate 7 is fixedly connected to the left end of the meshing toothed plate 6, and the lower end of the L-shaped plate 7 is fixedly connected to the base 1. Two support sliders 4 are fixedly connected to the lower end of the paper placement plate 3. The two support sliders 4 are slidably connected to two limiting rods 12 respectively. The front and rear ends of the two limiting rods 12 are fixedly connected to the relatively close ends of the two fixed plates 13 respectively. The L-shaped plate 7 can fix the meshing toothed plate 6. The mutual cooperation between the fixed plates 13, the support sliders 4 and the limiting rods 12 can limit the movement direction of the paper placement plate 3.

[0033] Furthermore, the paper fixing assembly 5 includes an L-shaped frame 56, the lower end of which is fixedly connected to the upper end of the paper placement plate 3. Two fixing plates 510 are fixedly connected to the left end of the L-shaped frame 56. The two fixing plates 510 are movably connected to the upper and lower sides of the threaded rod 59, respectively. A meshing gear 58 is fixedly connected to the lower end of the threaded rod 59, meshing with a meshing toothed plate 6. The threaded rod 59 is threadedly connected to a connecting plate 55 with internal threaded holes. The connecting plate 55 is slidably connected to two limiting rods 57 through two internal limiting holes. The upper and lower ends of the two limiting rods 57 are fixedly connected to the relatively close ends of the two fixing plates 510. The connecting plate 55 is slidably connected to two T-shaped guide rods 53 through two internal guide holes on its right side. The lower ends of both T-shaped guide rods 53 are fixedly connected to a pressure plate 52, and an anti-slip pad is provided at the lower end of the pressure plate 52. 51. Springs 54 are fitted onto both T-shaped guide rods 53. During the process of moving the paper placement plate 3 backward, the engagement of the meshing toothed plate 6 and the meshing gear 58 can drive the threaded rod 59 to rotate. The rotation of the threaded rod 59, under the action of the limiting rod 57, can drive the connecting plate 55 to move downward. Then, with the cooperation of the T-shaped guide rods 53 and the springs 54, the pressure plate 52 can be moved downward a specified distance, thereby achieving the effect of fixing the paper on the paper placement plate 3. In addition, during the process of fixing the paper, the anti-slip pad 51 can not only increase the stability of the fixing process, but also protect the surface of the paper. After the paper is fixed, the meshing toothed plate 6 and the meshing gear 58 are no longer engaged, and the paper placement plate 3 can continue to move backward.

[0034] The paper leveling component 8 includes a T-shaped plate 87. The left end of the T-shaped plate 87 is fixedly connected to the right end of the electric telescopic rod body 9. The T-shaped plate 87 is slidably connected to two limiting rods 11 through limiting holes opened inside both its front and rear ends. An electric push rod body 88 is fixedly installed at the lower end of the T-shaped plate 87. The lower end of the electric push rod body 88 is fixedly connected to the upper end of the mounting plate 84. The lower end of the mounting plate 84 is provided with an air duct 89, a heating pressure roller 82, and a leveling scraper 81. The front end of the air duct 89 is fixedly connected to one end of a connecting conduit 83. The other end of the connecting conduit 83 is fixedly connected to the front end of a fan body 85. The fan body 85 is fixedly installed on the upper end of the mounting plate 84. Four T-shaped guide rods 86 are fixedly connected to the upper end of the mounting plate 84. The four T-shaped guide rods 86 are all slidably connected to the T-shaped plate 87, which has four guide holes opened inside its lower end. The T-shaped guide rods 86 and the T-shaped plate 87 are connected to each other. The interaction between the components restricts the movement of the mounting plate 84. By activating the electric push rod body 88, the mounting plate 84 moves downward, allowing the heating roller 82 and the flattening scraper 81 to overlap the upper end of the paper. Then, by activating the electric telescopic rod body 9, the T-shaped plate 87 moves to the right. With the cooperation of the T-shaped guide rod 86 and the mounting plate 84, the heating roller 82 and the flattening scraper 81 move to the right. During this process, the heating roller 82 and the flattening scraper 81 not only smooth out the paper wrinkles but also heat and shape the smoothed paper. After the paper is heated and shaped, the fan body 85, the connecting duct 83, and the air duct 89 work together to quickly cool the heated part of the paper, thereby improving the smoothing and shaping effect of the paper.

[0035] The working principle of this utility model is as follows:

[0036] When using this device to flatten paper, first lay the paper flat on the upper part of the paper placement plate 3, ensuring that the left end of the paper is close to the right side of the L-shaped frame 56. Then, activate the electric telescopic rod body 2 to move the push-pull plate 14 backward. With the cooperation of the support slider 4 and the limiting rod 12, the paper placement plate 3 can be moved backward until the paper is moved to the underside of the paper flattening component 8. During the backward movement of the paper placement plate 3, the engagement tooth plate 6 and the engagement gear 58 can rotate the threaded rod 59. The rotation of the threaded rod 59, under the action of the limiting rod 57, can move the connecting plate 55 downward. Then, with the cooperation of the T-shaped guide rod 53 and the spring 54, the pressure plate 52 can be moved downward a specified distance, thus achieving the effect of fixing the left end of the paper. After the paper is fixed, the meshing toothed plate 6 begins to separate from the meshing toothed plate 6 to avoid affecting the continued backward movement of the paper placement plate 3. After the paper placement plate 3 moves to below the heating pressure roller 82 and the flattening scraper 81, the electric push rod body 88 is activated to drive the mounting plate 84 downward, which in turn drives the heating pressure roller 82 and the flattening scraper 81 downward and overlaps the upper end of the paper. At this time, the electric telescopic rod body 9 is activated to push the T-shaped plate 87 to the right. With the cooperation of the set T-shaped guide rod 86 and the mounting plate 84, the heating pressure roller 82 and the flattening scraper 81 can be driven to the right, thereby achieving the flattening and heating and shaping process of the paper. During this process, with the cooperation of the set fan body 85, connecting duct 83 and air duct 89, the paper after heating and shaping can be cooled quickly, thereby ensuring the flattening and shaping effect of the device on the paper.

[0037] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
