Description

Technical Field

[0001] This invention relates to the field of stamping, and more specifically, to a continuous automatic stamping machine with multi-stage fine-tuning. Background Technology

[0002] In daily life, some enterprises or organizations often issue batches of various documents, such as notices and reports. Each document needs to be stamped. In existing technology, the stamp is usually driven by a motor to move up and down, and then the paper is continuously passed under the stamp by a paper transfer device. The stamp will stamp the paper as it moves up and down, thus achieving continuous automatic stamping.

[0003] However, compared with existing automatic stamping machines, the following drawbacks were found:

[0004] 1. When issuing different documents, the position of the stamp on the document may change, requiring adjustment of the stamp. Current technology generally uses bolts for fastening, which is quite troublesome to adjust and results in poor versatility.

[0005] 2. When multiple stamps are required on a published document, the existing technology generally involves stamping once, changing the stamp, adjusting the stamp position, and then stamping the document with the new stamp again. This makes the operation steps cumbersome and affects work efficiency.

[0006] 3. After repeated stamping, the ink on the stamp will gradually decrease, resulting in unclear stamps on documents. It is necessary to reapply ink to the stamp periodically, which makes the automatic stamping machine inconvenient to use and requires improvement.

[0007] To address this, a continuous automatic stamping machine with multi-level fine-tuning for movement is proposed. Summary of the Invention

[0008] To address the problems existing in the prior art, the purpose of this invention is to provide a continuous automatic stamping machine with multi-level fine-tuning. It can control the magnetism of the magnetic plate by electromagnet, and then use the magnetic plate to magnetically attract the magnetic block. The position adjustment of the stamp is simple and convenient through magnetic attraction. At the same time, multiple sets of stamps can be added at one time for synchronous stamping operation, thereby improving the working efficiency of the stamping machine.

[0009] To solve the above problems, the present invention adopts the following technical solution.

[0010] A continuous automatic stamping machine with multi-level travel fine adjustment includes a housing, a paper feeding box installed on the left side of the housing, a paper receiving box installed on the right side of the housing, a first motor fixedly installed on the side surface of the housing, a lead screw fixedly installed at the output end of the first motor, and a threaded sleeve connected to the outer circular surface of the lead screw.

[0011] An adjustment mechanism, located inside the housing, is used to quickly adjust the position of the stamp, and the adjustment mechanism is connected to a threaded sleeve;

[0012] The paper feeding mechanism, located inside the paper tray, is used to transport documents from the paper tray into the housing for stamping.

[0013] Furthermore, a first connecting shaft is fixedly connected to the side surface of the threaded sleeve. One end of the first connecting shaft extends into the housing and is connected to a magnetic plate. An electromagnet is fixedly connected to the center of the upper surface of the magnetic plate. A magnetic block is provided below the magnetic plate, and a clamping mechanism is provided below the magnetic block. The clamping mechanism is used to clamp the seal.

[0014] Furthermore, the clamping mechanism includes a fixed plate, a first clamping plate, a second clamping plate, a bolt, and an air cushion; the first clamping plate is fixedly connected to the left end of the lower surface of the fixed plate, a bolt is provided through the right side of the fixed plate, the left end of the bolt is rotatably connected to the second clamping plate, and air cushions are fixedly connected to the adjacent surfaces of the first clamping plate and the second clamping plate.

[0015] Furthermore, a lifting block and a storage cylinder are provided between the magnetic block and the fixing plate. The lifting block and the storage cylinder are connected through each other. The upper end of the lifting block is fixedly connected to the magnetic block, and the lower end of the storage cylinder is fixedly connected to the fixing plate. A first spring is provided inside the storage cylinder near the lower end. The upper end of the first spring is fixedly connected to the lifting block. The inner wall of the storage cylinder has evenly distributed fixing grooves on both the left and right sides. The left and right side surfaces of the lifting block are fixedly connected to the lower end with spring pieces. The spring pieces are engaged with the fixing grooves. A control rod is fixedly connected to one side of the spring piece.

[0016] Furthermore, an inkpad box is installed at the upper end of the inner wall of the housing, and a flipping mechanism is provided on the side of the magnetic plate away from the first connecting shaft. The flipping mechanism is used to control the stamp to flip 180° after stamping.

[0017] Furthermore, the flipping mechanism includes a rotating block, a first permanent magnet block, a sliding groove, and a second permanent magnet block; a sliding groove is provided at the end of the side wall of the housing away from the first motor, the sliding groove is composed of a vertical groove and a fan-shaped groove, a rotating block is arranged in the sliding groove, a second connecting shaft is fixedly connected to the side surface of the rotating block, one end of the second connecting shaft is fixedly connected to a magnetic guide plate, the first permanent magnet block is fixedly connected to the upper end of the rotating block, the second permanent magnet block is installed on the concave arc surface of the fan-shaped groove, and the magnetic guide plate is rotatably connected to the first connecting shaft.

[0018] Furthermore, a sealing plate is slidably connected to the inner wall of the shell at the position below the inkpad box.

[0019] Furthermore, a top plate is rotatably connected to the inner wall of the paper tray, and a second spring is fixedly connected to the lower surface of the top plate. The lower end of the second spring is fixedly connected to the bottom of the paper tray. A second motor is installed on the outer surface of the paper tray, and the output end of the second motor passes through the side wall of the paper tray and is fixedly connected to a paper feeding roller.

[0020] Furthermore, a paper separating pad is installed on the right side of the inner wall of the paper box, and the upper surface of the paper separating pad has a rough design.

[0021] Furthermore, a first paper feeding roller is installed near the center of the inner bottom of the housing, and a second paper feeding roller is installed near the right side of the inner bottom of the housing. Both the first and second paper feeding rollers are driven by a motor, and an infrared sensor is installed near the second paper feeding roller on the inner bottom of the housing.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] (1) This solution controls the magnetism of the magnetic plate by electromagnet, and then uses the magnetic plate to magnetically attract the magnetic block. The position adjustment of the stamp is simple and convenient by magnetic attraction. At the same time, multiple sets of stamps can be added at one time for synchronous stamping operation, which improves the working efficiency of the stamping machine.

[0024] (2) When multiple sets of stamps are used for stamping at one time, this solution achieves the same level of stamping surface by adjusting the depth of the corresponding lifting blocks entering the storage tube, thus ensuring that multiple sets of stamps can stamp out patterns.

[0025] (3) After each stamping, the flipping mechanism controls the stamp to flip 180° and then continue to move upwards, and contact the inkpad to add ink to the stamp. When the stamp moves downwards, the flipping mechanism controls the stamp to rotate 180° in the opposite direction and continue to move downwards to stamp, so that ink can be applied after each stamping, ensuring the clarity of the stamp pattern.

[0026] (4) This solution utilizes the fact that the friction between the paper and the paper separating pad is greater than the friction between the paper and the paper. When multiple sheets move obliquely upward, the bottom sheet contacts the paper separating pad. Because the friction between the paper and the paper separating pad is greater than the friction between the paper and the paper, the bottom sheet stops moving obliquely upward. Then, the second sheet below contacts the paper separating pad. This process is repeated until the paper feeding roller can only feed a single sheet of paper into the housing.

[0040] 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.

[0041] Example 1

[0042] Please see Figures 1 to 7 A continuous automatic stamping machine with multi-stage fine-tuning includes a housing 1. A paper tray 2 is installed on the left side of the housing 1. Paper to be stamped is placed into the paper tray 2. A paper feeding mechanism is set inside the paper tray 2 to transport documents from the paper tray 2 to the housing 1 for stamping. A first motor 4 is fixedly installed on the side surface of the housing 1. A lead screw 5 is fixedly installed at the output end of the first motor 4. The first motor 4 can control the forward and reverse rotation of the lead screw 5. A threaded sleeve 6 is threadedly connected to the outer surface of the lead screw 5. The lead screw 5 rotates forward and backward. The movement of the threaded sleeve 6 along the screw 5 causes it to move up and down. An adjustment mechanism, located inside the housing 1, is used to quickly adjust the position of the stamp. This mechanism is connected to the threaded sleeve 6. A first connecting shaft 7 is fixedly connected to the side surface of the threaded sleeve 6. One end of the first connecting shaft 7 extends into the housing 1 and is connected to a magnetic plate 8. When the threaded sleeve 6 moves up and down, it synchronously drives the first connecting shaft 7 and the magnetic plate 8 to move together. An electromagnet 9 is fixedly connected to the center of the upper surface of the magnetic plate 8, and a magnetic block is located below the magnetic plate 8. 10. A clamping mechanism is provided below the magnetic block 10. The clamping mechanism is used to clamp the stamp. A document is fed into the bottom of the housing 1 using the paper feeding mechanism. Then, the clamped stamp is placed on the document at the stamping position. At this time, the electromagnet 9 is energized and generates magnetism, and the magnetic plate 8 also becomes magnetic. When the magnetic plate 8 moves downward, it will attract the magnetic block 10, thus fixing the magnetic block 10 and fixing the stamp. The first motor 4 drives the magnetic plate 8 to move up and down, thereby moving the stamp up and down. When the stamp moves downward, it achieves... The document below is stamped. A paper receiving box 3 is installed on the right side of the housing 1. When the stamp moves up, the component at the bottom of the housing 1 will transport the stamped document into the paper receiving box 3. When multiple stamps are needed on the document, magnetic blocks 10 can be added. The stamp is clamped under the magnetic blocks 10. Multiple sets of magnetic blocks 10 can be magnetically attracted under the magnetic plate 8. The position adjustment of the stamp is simple and convenient through magnetic attraction. At the same time, multiple sets of stamps can be added at one time for synchronous stamping operation, which improves the working efficiency of the stamping machine.

[0043] like Figures 5 to 6 and Figure 11As shown, the clamping mechanism includes a fixed plate 11, a first clamping plate 12, a second clamping plate 13, a bolt 14, and an air cushion 15. The first clamping plate 12 is fixedly connected to the left end of the lower surface of the fixed plate 11. The bolt 14 is provided through the right side of the fixed plate 11. By rotating the bolt 14 in both directions, the insertion amount of the bolt 14 into the fixed plate 11 can be controlled. The second clamping plate 13 is rotatably connected to the left end of the bolt 14. By controlling the insertion amount of the bolt 14, the distance between the second clamping plate 13 and the first clamping plate 12 can be controlled. A stamp can be placed between the second clamping plate 13 and the first clamping plate 12 to clamp the stamp. Air cushions 15 are fixedly connected to the adjacent surfaces of the first clamping plate 12 and the second clamping plate 13. The air cushions 15 have strong deformation ability, which can increase the contact area with the stamp and improve the friction, thereby increasing the fixing effect of the stamp.

[0044] like Figures 5 to 7 As shown, when using multiple sets of stamps at once, the stamps are of different sizes and heights. To ensure that the stamping surfaces are on the same horizontal plane, this invention provides a lifting block 16 and a storage cylinder 17 between the magnetic block 10 and the fixing plate 11. The lifting block 16 and the storage cylinder 17 are connected through each other. The upper end of the lifting block 16 is fixedly connected to the magnetic block 10, and the lower end of the storage cylinder 17 is fixedly connected to the fixing plate 11. A first spring 21 is provided inside the storage cylinder 17 near the lower end. The upper end of the first spring 21 is fixedly connected to the lifting block 16. The inner wall of the storage cylinder 17 has evenly distributed fixing grooves 18 on both the left and right sides. The left and right side surfaces of the lifting block 16 are fixedly connected to the lower end with spring pieces 19. The spring pieces 19 are engaged with the fixing grooves 18. A control rod 20 is fixedly connected to one side of the spring piece 19.

[0045] By adopting the above technical solution, the stamp is first fixed by a clamping mechanism and placed at the position to be stamped on the document. At this time, the heights of the magnetic blocks 10 are different. Then, the magnetic plate 8 is controlled to move downward. The magnetic plate 8 will eventually squeeze the magnetic blocks 10 below, and the magnetic blocks 10 will squeeze the lifting block 16. The lifting block 16 will move into the storage cylinder 17. At the same time, the first spring 21 is compressed. When the lifting block 16 moves downward, the spring piece 19 will continuously deform and get into the corresponding fixing groove 18. When the lifting block 16 moves downward, the stamping surface of the seal is controlled to be on the same horizontal plane. The spring 19 is locked in the fixing groove 18. When the lifting block 16 moves upward, the spring 19 is resisted by the inner wall of the fixing groove 18 and cannot move, thus fixing the lifting block 16. Then the stamping work can be carried out. When it is necessary to return the lifting block 16 to the initial position, pinch the two sets of control rods 20 to drive the spring 19 to disengage from the fixing groove 18. The first spring 21 will push the lifting block 16 back to the initial position, and then release the control rods 20.

[0046] like Figures 1 to 4 and Figures 8 to 9As shown, an inkpad box 22 is installed at the upper end of the inner wall of the housing 1. A flipping mechanism is provided on the side of the magnetic plate 8 away from the first connecting shaft 7. The flipping mechanism is used to control the stamp to flip 180° after stamping. After each stamping, the stamp is controlled to flip 180° by the flipping mechanism and then continue to move upward and contact the inkpad box 22 to add ink to the stamp. When the stamp moves downward, the flipping mechanism controls the stamp to rotate 180° in the opposite direction and continue to move downward to stamp, so that ink can be applied after each stamping to ensure the clarity of the stamp pattern.

[0047] like Figures 1 to 4 and Figures 8 to 9 As shown, the flipping mechanism includes a rotating block 24, a first permanent magnet block 25, a sliding groove 26, and a second permanent magnet block 27. A sliding groove 26 is provided at the end of the side wall of the housing 1 away from the first motor 4. The sliding groove 26 consists of a vertical groove and a fan-shaped groove. A rotating block 24 is disposed within the sliding groove 26. When the rotating block 24 moves downward from the upper end of the sliding groove 26, the upper end of the rotating block 24 is fixedly connected to the first permanent magnet block 25. The concave arc surface of the fan-shaped groove is fitted with the second permanent magnet block 27. When the first permanent magnet block 25 enters the fan-shaped groove, it will be attracted by the second permanent magnet block 27 and deflect. A second connecting shaft 23 is fixedly connected to the side surface of the rotating block 24. When the rotating block 24 deflects, it will drive the second permanent magnet block 27. The connecting shaft 23 deflects synchronously. One end of the second connecting shaft 23 is fixedly connected to the magnetic plate 8. The second connecting shaft 23 will drive the magnetic plate 8 to deflect synchronously. The magnetic plate 8 is rotatably connected to the first connecting shaft 7 to ensure that the magnetic plate 8 can be rotated. The rotating block 24 will rotate 180° in the fan-shaped groove, and at the same time drive the magnetic plate 8 to flip to ensure that the stamping surface of the seal is facing down. Then the stamping operation is performed. After the stamping is completed, when the rotating block 24 moves upward from the bottom of the slide 26, the rotating block 24 will rotate 180° in the opposite direction when passing through the fan-shaped groove to ensure that the stamping surface of the seal is facing up. Finally, it contacts the inkpad box 22 to achieve the purpose of moistening the seal with ink.

[0048] like Figures 1 to 2 As shown, a sealing plate 28 is slidably connected to the inner wall of the housing 1 below the inkpad 22. When the stamping machine is not in use, in order to prevent the inkpad inside the inkpad 22 from drying out, the sealing plate 28 is inserted below the inkpad 22 to prevent the inkpad inside the inkpad 22 from contacting the air and thus prevent the inkpad from drying out.

[0049] like Figure 10As shown, a top plate 29 is rotatably connected to the inner wall of the paper tray 2. The document to be stamped is on the upper surface of the top plate 29. A second spring 30 is fixedly connected to the lower surface of the top plate 29. The lower end of the second spring 30 is fixedly connected to the bottom of the paper tray 2. The second spring 30 will push the top plate 29. A second motor 31 is installed on the outer surface of the paper tray 2. The output end of the second motor 31 passes through the side wall of the paper tray 2 and is fixedly connected to a paper feed roller 32. The top plate 29 pushes the paper document to ensure that the paper is in close contact with the paper feed roller 32. The second motor 31 controls the paper feed roller 32 to rotate. The paper feed roller 32 will drive the paper to move towards the bottom of the housing 1 to realize the paper delivery.

[0050] like Figure 10 As shown, when the paper feed roller 32 moves the paper obliquely, due to the friction between the papers, multiple sheets of paper move together. In this invention, a paper separating pad 33 is installed on the right side of the inner wall of the paper tray 2. The upper surface of the paper separating pad 33 is rough, so that the friction between the paper and the paper separating pad 33 is greater than the friction between the papers. When multiple sheets move obliquely upward, the bottom sheet of paper contacts the paper separating pad 33. Because the friction between the paper and the paper separating pad 33 is greater than the friction between the papers, the bottom sheet stops moving obliquely upward. Then, the second sheet of paper below contacts the paper separating pad 33, and so on. Finally, the paper feed roller 32 can only feed a single sheet of paper into the housing 1.

[0051] like Figure 10 As shown, a first paper feed roller 34 is installed near the center of the inner bottom of the housing 1, and a second paper feed roller 35 is installed near the right side of the inner bottom of the housing 1. An infrared sensor 36 is installed near the second paper feed roller 35 on the inner bottom of the housing 1. When paper enters the inner bottom of the housing 1 and attaches to the infrared sensor 36, the sensor detects that the paper has been laid flat, the second motor 31 stops working, and the paper feeding roller 32 stops feeding the paper. Then, the stamping process begins. After the stamping is completed, the first paper feed roller 34 and the second paper feed roller 35 rotate in the same direction. Both the first paper feed roller 34 and the second paper feed roller 35 are driven by motors. The surfaces of the first paper feed roller 34 and the second paper feed roller 35 are designed with a rough surface to ensure that the stamped document can be transported to the receiving box 3 during rotation. When the paper is no longer attached to the infrared sensor 36, the sensor detects that there is no paper document on the inner bottom of the housing 1. Then, the second motor 31 starts working, and the paper feeding roller 32 feeds the paper.

[0052] Instructions for use: Place the paper to be stamped into the paper tray 2. The paper feeding roller in the paper feeding mechanism transports the document from the paper tray 2 into the housing 1. The paper is attached to the infrared sensor 36 at the bottom of the housing 1. Once the paper is detected as flat, the paper feeding roller 32 stops feeding, and the stamping process begins. The first motor 4 controls the forward and reverse rotation of the lead screw 5. This forward and reverse rotation of the lead screw 5 causes the threaded sleeve 6 to move up and down along the lead screw 5. The threaded sleeve 6, while moving up and down, synchronously drives the first connecting shaft 7 and the magnetic plate 8 to move together. The magnetic block 10 is located below... A clamping mechanism is provided to hold the stamp. A document is fed into the bottom of the housing 1 using a paper feeding mechanism. The clamped stamp is then placed on the document at the stamping position. At this time, the electromagnet 9 is energized and generates magnetism, and the magnetic plate 8 also becomes magnetic. When the magnetic plate 8 moves downward, it attracts the magnetic block 10, thus fixing the magnetic block 10 and fixing the stamp. The first motor 4 drives the magnetic plate 8 to move up and down, thereby moving the stamp up and down. When the stamp moves downward, it stamps the document below. A paper receiving box 3 is installed on the right side of the housing 1. As the machine moves upward, the components at the bottom of the housing 1 transport the stamped document into the receiving tray 3. When multiple stamps are required on the document, magnetic blocks 10 are added. The stamps are held in place below the magnetic blocks 10. Multiple sets of magnetic blocks 10 can be magnetically attracted below the magnetic plate 8. Adjusting the stamp position via magnetic attraction is simple and convenient. Multiple sets of stamps can also be added simultaneously for synchronous stamping, improving the machine's efficiency. After each stamping operation, the stamp is rotated 180° by the flipping mechanism and then continues to move upward, contacting the inkpad 2. 2. To add ink to the stamp, the flipping mechanism controls the stamp to rotate 180° in the opposite direction as the stamp moves down, and continues to move down to stamp. This ensures that ink is applied after each stamping, guaranteeing the clarity of the stamped pattern. After stamping, the first paper feeding roller 34 and the second paper feeding roller 35 rotate in the same direction to ensure that the stamped document is delivered to the receiving box 3 during rotation. When the paper is no longer attached to the infrared sensor 36, it is detected that there is no paper document at the bottom of the inner shell 1. Then the second motor 31 works, and the paper feeding roller 32 performs paper feeding again.
