Description

A document positioning and adjustment mechanism for printing control instruments Technical Field

[0001] This invention relates to the field of printing control instruments, and more specifically, to a document positioning and adjustment mechanism for printing control instruments. Background Technology

[0002] The intelligent seal control machine can load multiple seals into the intelligent seal control device, specify the seal location, and realize automated and intelligent seal application. The device integrates multiple functions such as scanning, printing, approval, stamping, and counterfeit detection. After online approval, it can free up manpower and quickly and efficiently complete self-service and automated seal application.

[0003] However, when using existing printing control devices, the document is placed on the platform, and then the clamps on both sides are used to fix the document to the platform surface. The printing control device is then used to press the document onto the object. However, when the document needs to be printed multiple times, it must be taken out, sorted, and fixed again each time before printing can be done. This process is cumbersome and repeated many times. Summary of the Invention

[0004] To address the problems existing in the prior art, the purpose of this invention is to provide a document positioning and adjustment mechanism for a printing control instrument. In this solution, after the cylinder rotates, the protrusions rotate, and the cylinder reaches the surface of the document again. The protrusions on the surface of the cylinder are located on both sides of the contact surface between the cylinder and the document, so that the cylinder can repeatedly rotate to drive the document to turn pages, making stamping more convenient. In addition, the cylinder can hold the document in place, making it easier to fix the document.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] A document positioning and adjustment mechanism for a printing control instrument includes a housing, a base fixedly connected to one side of the bottom of the housing, and a limiting mechanism and a paper picking mechanism respectively provided on the front and rear sides of the top of the base.

[0007] The limiting mechanism includes a movable frame slidably connected to the front end of the top of the base, a pull rod slidably connected to the middle of the movable frame, a limiting block fixedly connected to the bottom of the pull rod, and a first spring sleeved on the surface of the pull rod, with the two ends of the first spring welded to the limiting block and the movable frame respectively.

[0008] The paper-taking mechanism includes support blocks slidably connected to both sides of the top rear end of the base. Each of the two support blocks has a bearing slidably connected inside. A cylinder is fixedly connected between the two bearings. Each of the two support blocks has a receiving groove inside to accommodate the movement of the bearing. The surface of the cylinder has multiple protrusions distributed in a ring array.

[0009] Furthermore, the upper end of the base has two inner limiting grooves on both sides to accommodate the movement of the support block and the moving frame. The two limiting grooves are rotatably connected to lead screws, which pass through the corresponding support block and the moving frame and are helically connected to the support block and the moving frame.

[0010] Furthermore, the outer rings of the two bearings extend to form second extension blocks on both the front and rear sides, and the interior of the two support blocks is provided with first sliding grooves corresponding to the movement trajectory of the second extension blocks. A second spring is welded into the interior of each of the multiple first sliding grooves.

[0011] Furthermore, the interior of the movable frame extends toward the position of the pull rod to form a first extension block, and the interior of the pull rod is provided with a longitudinal groove corresponding to the position of the first extension block, and an annular groove is provided at the bottom of the outer groove of the pull rod.

[0012] Furthermore, the cross-sectional shape of the limiting block is fan-shaped.

[0013] Furthermore, a drying mechanism is provided on the front side of each of the two support blocks. Each of the two drying mechanisms includes a housing fixedly connected to the front side of the support block. A motor is fixedly connected inside each of the two housings, and a fan blade is fixedly connected to the end of the output shaft of each of the two motors.

[0014] Furthermore, both sides of the two housings are fixedly connected with circular perforated discs, and the interior of the multiple circular perforated discs is provided with circular holes arranged in a ring array.

[0015] Furthermore, a platform is fixedly connected to the top of the base, and a heating plate is slidably connected inside the platform. The heating plate consists of a central sheet-like part and two annular parts on both sides.

[0016] Furthermore, the two sides of the cylinder are respectively fixed to the inner sides of the inner rings of the two bearings.

[0017] Furthermore, all of the aforementioned protrusions are made of elastic rubber.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. In this solution, the raised blocks rotate after the cylinder rotates, and the cylinder reaches the surface of the document again. The raised blocks on the surface of the cylinder are located on both sides of the contact surface between the cylinder and the document, which allows the cylinder to rotate repeatedly to drive the document to turn pages, making stamping more convenient. In addition, the cylinder can hold the document in place, making it easier to fix the document.

[0020] 2. This solution allows for adjustment of the positions of the paper feeding mechanism and the limiting mechanism by rotating the lead screw, based on the paper size. As the support block and the moving frame move, the limiting groove restricts the support block and the moving frame, making the movement more stable and preventing the cylinder and the limiting block from shifting off the paper, which could cause the stamp to shift.

[0021] 3. This solution moves the bearing by pulling the cylinder, and when the cylinder is released, it returns to its original position under the elasticity of the second spring. This ensures that the cylinder continuously restricts the document under the elasticity of the second spring, resulting in a better document restriction effect.

[0022] 4. This solution uses a limiting block to restrict the document, with the curved surface of the limiting block facing the document. When the document is pulled from one side of the support block, the paper does not come into contact with the edge of the limiting block, so the paper will not be damaged when pulled, and the paper is better protected when pulled. The edge of the limiting block comes into contact with the paper, which is suitable for documents such as books that are fixed on one side, making the fixation effect better.

[0023] 5. This solution allows for simultaneous adjustment of the air outlet position of the housing by adjusting the support block, making it more suitable for corresponding documents. The fan blades driven by the motor generate airflow, which reaches the stamping position through the circular plate, allowing the stamped seal to dry faster. In addition, drying mechanisms are provided on both sides of the base for better drying effect.

[0024] 6. This solution uses a heating plate that is always below the stamping position to heat the document, making the stamp dry faster. The heating plate extends into the interior of the housing on both sides, allowing it to heat the air inside the housing. The fan blades also blow out hot air, further accelerating the drying of the stamp. Attached Figure Description

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0036] Example 1

[0037] Please refer to Figures 1 to 2 and Figures 4 to 8. A document positioning and adjustment mechanism for a printing control instrument includes a housing 1. A base 2 is fixedly connected to one side of the bottom of the housing 1. A limiting mechanism 3 and a paper-taking mechanism 4 are respectively provided on the front and rear sides of the top of the base 2. The limiting mechanism 3 includes a movable frame 31 slidably connected to the front end of the top of the base 2. A pull rod 33 is slidably connected to the middle of the movable frame 31. A limiting block 32 is fixedly connected to the bottom of the pull rod 33. A first spring 34 is sleeved on the surface of the pull rod 33. The two ends of the first spring 34 are welded to the limiting block 32 and the movable frame 31, respectively. The paper-taking mechanism 4 includes support blocks 42 slidably connected to the rear ends of the top of the base 2. A bearing 43 is slidably connected inside each of the two support blocks 42. A cylinder 41 is fixedly connected between the two bearings 43. A receiving groove 421 for accommodating the movement of the bearing 43 is opened inside each of the two support blocks 42. Multiple protrusions 411 are distributed in a ring array on the surface of the cylinder 41.

[0038] First, pull the lever 33, causing it to move downwards along with the limiting block 32. During this movement, the lever 33 compresses the first spring 34, lifting the limiting block 32 and placing the organized document on top of the base 2. Then, release the lever 33, and the limiting block 32 returns to its original position under the elasticity of the first spring 34. The bottom of the limiting block 32 compresses and restricts the document. By pulling the cylinder 41, the cylinder 41, along with the bearing 43, moves inside the support block 42, placing the other side of the document at the bottom of the cylinder 41. The cylinder 41 then restricts the document, while the protrusions 411 on the surface of the cylinder 41 are located on both sides of the contact surface between the cylinder 41 and the document, but the protrusions 411 do not contact the document. The document is then printed through the outer casing 1. When printing is finished and a page needs to be turned, the cylinder 41 is rotated, causing the protrusions 411 on its surface to rotate as well. The rotation of the protrusions 411 brings them into contact with the document, and the high coefficient of friction of the protrusions 411 causes the first page of the document to turn. Subsequent pages of the document do not come into contact with the protrusions 411, keeping them in their original position. After the cylinder 41 rotates, the protrusions 411 rotate, and the cylinder 41 reaches the surface of the document again. The protrusions 411 on the surface of the cylinder 41 are located on both sides of the contact surface between the cylinder 41 and the document, allowing the cylinder 41 to rotate repeatedly to drive the document to turn pages. This makes stamping more convenient, eliminating the need to repeatedly release the paper before it can be removed.

[0039] As shown in Figure 4, the upper sides of the base 2 are provided with limiting grooves 21 to accommodate the movement of the support block 42 and the moving frame 31. The two limiting grooves 21 are rotatably connected with lead screws 7. The two lead screws 7 pass through the corresponding support block 42 and the moving frame 31 and are screwed to the support block 42 and the moving frame 31.

[0040] By rotating the lead screw 7, the lead screw 7 rotates inside the base 2. While rotating, it drives the support block 42 and the moving frame 31 to move. The position of the paper feeding mechanism 4 and the limiting mechanism 3 can be adjusted according to the size of the paper. While the support block 42 and the moving frame 31 move, the limiting groove 21 restricts the support block 42 and the moving frame 31, making the movement more stable and preventing the cylinder 41 and the limiting block 32 from shifting their fixation on the paper, which would cause the stamp to shift.

[0041] As shown in Figure 7, the outer rings of the two bearings 43 extend to form second extension blocks 45 on both the front and rear sides. The interiors of the two support blocks 42 are provided with first grooves 422 corresponding to the movement trajectory of the second extension blocks 45. The interiors of the multiple first grooves 422 are each welded with a second spring 44.

[0042] While the cylinder 41 is being pulled and the bearing 43 is being moved, the second extension blocks 45 on both sides of the bearing 43 move inside the first groove 422, causing the second extension blocks 45 to compress the second spring 44 inside the first groove 422. After the cylinder 41 is released, it returns to its original position under the elasticity of the second spring 44, so that the cylinder 41 continues to restrict the document under the elasticity of the second spring 44, resulting in a better document restriction effect.

[0043] As shown in Figure 1, the interior of the movable frame 31 extends toward the position of the pull rod 33 to form a first extension block 311. The interior of the pull rod 33 is provided with a longitudinal groove 331 corresponding to the position of the first extension block 311. The bottom of the groove on the outer side of the pull rod 33 is provided with an annular groove 332. The cross-sectional shape of the limiting block 32 is fan-shaped.

[0044] The document is restrained by the limiting block 32, with the arc-shaped surface of the limiting block 32 facing the document. When the document is pulled from one side of the support block 42, the paper of the document does not come into contact with the edge of the limiting block 32, so the paper will not be damaged when pulled and the paper is better protected. After pulling the lever 33, the first extension block 311 is in the position of the annular groove 332. The lever 33 can rotate and rotate the limiting block 32, so that the edge of the limiting block 32 comes into contact with the paper. This is suitable for documents such as books that are fixed on one side, and makes the fixing effect better.

[0045] As shown in Figures 5 and 6, a drying mechanism 5 is provided on the front side of each of the two support blocks 42. Each of the two drying mechanisms 5 includes a housing 51 fixedly connected to the front side of the support block 42. A motor 54 is fixedly connected inside each of the two housings 51. A fan blade 55 is fixedly connected to the end of the output shaft of each of the two motors 54.

[0046] The support block 42 moves along with the housing 51, allowing the housing 51 to adjust its air outlet position simultaneously with the adjustment of the support block 42, making it more suitable for the corresponding documents. The motor 54 drives the fan blades 55 to generate air, which reaches the stamping position through the circular plate 53, allowing the stamped seal to dry faster. Furthermore, drying mechanisms 5 are provided on both sides of the base 2, resulting in better drying effect.

[0047] As shown in Figure 3, two circular perforated plates 53 are fixedly connected to both sides of the two housings 51. The interior of the multiple circular perforated plates 53 is provided with circular holes arranged in a ring array. The top of the base 2 is fixedly connected to a platform 6. A heating plate 52 is slidably connected inside the platform 6. The heating plate 52 is composed of a central sheet and two annular sections on both sides. The two sides of the cylinder 41 are fixed to the inner sides of the inner rings of the two bearings 43 respectively. The material of the multiple protrusions 411 is elastic rubber.

[0048] As the housing 51 moves, it also moves the heating plate 52 inside the platform 6, keeping the heating plate 52 below the stamping position. This heats the document, making the stamp dry faster. The heating plate 52 extends into the housing 51 on both sides, heating the air inside the housing 51. The fan blades 55 rotate and blow out hot air, further accelerating the drying of the stamp.

[0049] Instructions for use: Rotate the lead screw 7 to position the paper feeding mechanism 4 and the limiting mechanism 3 to the appropriate position for the document. Pull the lever 33 to lift the limiting block 32 and place the organized document on top of the base 2. Then release the lever 33 to return to the original position and compress and limit the document. Pull the cylinder 41 to place the other side of the document at the bottom of the cylinder 41. Print the document through the outer casing 1. When it is necessary to turn the page after printing, rotate the cylinder 41. The rotation of the protrusion 411 contacts the document, and the protrusion 411 turns the first page of the document. The cylinder 41 can be rotated repeatedly to drive the document to turn the page. As the casing 51 moves, it also moves the heating plate 52 inside the platform 6, keeping the heating plate 52 below the stamping position to heat the document and make the stamp dry faster. The heating plate 52 extends into the interior of the casing 51 on both sides, so that the heating plate 52 heats the air inside the casing 51. The fan blades 55 rotate and blow out hot air.

[0050] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
