An automatic positioning stamping device

Abstract

This invention belongs to the technical field of stamping devices and addresses the problem in existing technologies where it is difficult to automatically add ink to stamps. Furthermore, during the stamping process, mechanical transmission is used to agitate the ink, preventing sedimentation due to prolonged static storage. Specifically, it is an automatic positioning stamping device, including a housing. The invention utilizes a brushing mechanism in conjunction with a first push rod to cause a magnetic ball to continuously oscillate within the ink tank, agitating the ink and preventing sedimentation that leads to uneven color distribution and affects the final product. Simultaneously, when the device is not in use for extended periods, a brush wheel wipes the ink off the outer wall of the stamp, preventing buildup that could affect the color and quality of the ink and print. The ink on the brush wheel is scraped off by protrusions and guided through a guide plate into the ink tank, allowing for ink reuse and preventing waste.

Description

Technical Field

[0001] This invention relates to the field of stamping device technology, specifically an automatic positioning stamping device. Background Technology

[0002] With the development of the times, in pursuit of efficient production and lifestyle, traditional manual stamping is labor-intensive and increases the probability of human error. Stamping is involved in various fields, from individuals to schools to enterprises, and its application is becoming increasingly widespread. Under the current standardized system, this application is particularly prominent. From a market perspective, there are relatively few types of automatic stamping machines, their functions are not comprehensive enough, and market demand is large. Furthermore, some stamping machines on the market are not practical enough, only able to complete a single stamping action, and still require human assistance to complete the stamping process, which does not fundamentally solve the practicality problem. Although a very small number of machines can complete a complete stamping operation, they are mostly large and heavy, causing significant inconvenience to users.

[0003] For example, in the patent document with publication number CN106476456B, the device clamps the stamp using a clamping device; the cam can rotate under the drive of the first power device and press down on the clamping device until the stamp is imprinted on the document to be stamped; at the same time, after the cam rotates away from the moving plate, the reset device can drive the clamping device to move upward, so that the paper feeding device can rub the stamped document off the placement block and repeat the automatic stamping action; however, the above patent does not have a component to cover or wipe the surface of the stamp, which means that dirt will accumulate on the surface of the stamp when it is not used for a long time.

[0004] In existing technologies, it is difficult to wipe the surface of the stamp to avoid the accumulation of dirt affecting the color and quality of the ink and print. It is also difficult to recycle the ink after wiping to prevent ink waste. At the same time, it is difficult to automatically add oil to the stamp. During the stamping process, it is difficult to stir the ink through mechanical transmission to prevent it from settling and causing uneven color distribution within the ink, which would affect the later use of the ink. Furthermore, it is difficult to assist in positioning the paper during the stamping process to prevent deviations.

[0005] To address the aforementioned technical shortcomings, a solution is proposed. Summary of the Invention

[0006] The purpose of this invention is to provide an automatic positioning stamping device. Through the cooperation of an oil-brushing mechanism and a first push rod, a magnetic ball continuously oscillates inside the oil replenishment tank, stirring the ink inside and preventing sedimentation that could lead to uneven color distribution and affect the final product's performance. Simultaneously, when the device is not in use for extended periods, a brush wheel wipes the ink off the outer wall of the stamp, preventing buildup from affecting the color and quality of the ink and print. The ink on the brush wheel is scraped off by protrusions and guided through a guide plate into the replenishment tank, allowing for ink reuse and preventing waste. This invention solves the problems of existing technologies, such as difficulty in wiping the stamp surface to prevent buildup affecting the color and quality of the ink and print, difficulty in recovering the wiped ink, difficulty in automatically refilling the stamp, and difficulty in assisting with paper positioning during the stamping process.

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

[0019] In this invention, the first push rod is controlled to move downward by the control panel. During the downward movement of the first push rod, the stamp comes into contact with the surface of the brushing roller, so that the surface of the stamp is brushed with oil. At the same time, the baffle plate squeezes the roller, so that the roller squeezes the lower pressure rod downward. The lower pressure rod pushes the positioning rod to move downward, so that several positioning parts on the positioning rod position the paper to be stamped, thus preventing deviation during the stamping process.

[0020] In this invention, an arc-shaped rod passes through an arc-shaped limiting groove and contacts the outer wall of the ink tank, causing the magnetic block and the magnetic ball to repel each other and push the magnetic ball to the middle of the ink tank. Then, the stamped seal moves upward. At this time, the arc-shaped rod is reset due to the action of the first push spring and the first pull spring, and the magnetic ball is reset. The magnetic block moves up and down with the first push rod and cooperates with the magnetic ball, so that the magnetic ball swings back and forth continuously inside the ink tank, stirring the ink inside the ink tank and preventing it from settling due to long-term stagnation, which would cause uneven color distribution inside the ink and affect the later use effect of the ink.

[0021] In this invention, when the device is not used for a long time, the first push rod is moved upward above the brush wheel, and the second push rod pushes the brush wheel on the ink replenishment tank below the stamp. The second push rod then reciprocates to push the ink replenishment tank, and the brush wheel wipes the ink on the outer wall of the stamp, preventing dirt buildup from affecting the color and quality of the ink and the printed image. The ink on the brush wheel is scraped off by the protrusions and enters the interior of the ink replenishment tank through the guide plate, allowing the ink to be reused and avoiding waste.

[0036] The supplementary component 24 includes an oil tank 241 fixedly connected to the output end of the second push rod 21. An oil filling port is provided on the top of the oil tank 241. Figure 6As shown, an oil-brushing groove 245 is fixedly provided on one side of the top of the oil tank 241. A brush wheel 244 is rotatably connected inside the oil-brushing groove 245 via a pin. A pull rope 242 is connected to the side of the oil tank 241 near the second push rod 21 via a connecting block. A magnetic ball 243 is fixedly connected to the bottom end of the pull rope 242. A guide plate 247 is fixedly connected to the outer wall of the oil tank 241 located below the brush wheel 244. A protrusion 246 is fixedly connected to the top of the guide plate 247. The protrusion 246 contacts the outer wall of the brush wheel 244. The input end of the oil inlet pipe 28 is connected to the output end of the oil tank 241. The magnetic ball 243 and the magnetic block repel each other; the middle of the oil inlet pipe 28 and the lower part of the oil supply pipe 27 are both elastic; when the device is not used for a long time, the first push rod 1 moves upward to above the brush wheel 244, and the second push rod 21 pushes the brush wheel 244 on the oil replenishment tank 241 to below the stamp, and causes the second push rod 21 to reciprocate to push the oil replenishment tank 241. The brush wheel 244 wipes the ink on the outer wall of the stamp to avoid the accumulation of dirt affecting the color and quality of the ink and the stamp. The ink on the brush wheel 244 is scraped off by the protrusion 246 and enters the interior of the oil replenishment tank 241 through the guide plate 247, so that the ink can be reused and the ink is not wasted.

[0037] The refueling assembly 25 includes a connecting frame 253 that is rotatably connected to the inner wall of the housing 8 via a pin. Two connecting ears are fixedly connected to the side of the connecting frame 253 near the placement platform. A limiting shaft is fixedly connected between the two connecting ears. A first tension spring is elastically provided between the limiting shaft and the bottom of the placement platform. A rotating shaft is rotatably connected to the end of the connecting frame 253 away from the placement platform via a bearing. An oil brush roller 251 is fixedly connected to the outer wall of the rotating shaft.

[0038] The rotating shaft has an internal cavity 254, and the brush roller 251 has an internal oil storage tank 256. The cavity 254 and the oil storage tank 256 are connected by several first connecting holes. A brush cloth 255 is fixedly connected to the outer wall of the brush roller 251, and the brush cloth 255 contacts the outer wall of the stamp. A humidity sensor is installed on the side wall of the brush roller 251 near the brush cloth 255. The oil storage tank 256 and the brush cloth 255 are connected by several second connecting holes.

A baffle plate 252 is fixedly connected to the outer wall of the connecting frame 253 located between the arc rod 23 and the brush roller 251. When the humidity sensor detects that the humidity on the brush cloth 255 is low, the printing oil inside the oil tank 241 is replenished into the cavity 254 by the liquid pump 26, and enters into the oil storage tank 256 through the first connecting hole. Then, the brush cloth 255 is wetted through the second connecting hole, and the device is automatically oiled.

[0039] Example 2

[0040] like Figure 1 , 7 As shown, the feeding mechanism 7 includes a first limiting roller 72 connected to the outer wall of the output end of the first push rod 1. A second limiting roller 73 is connected to the outer wall of the housing 8 above the first limiting roller 72. A traction rope 71 is fixedly connected to the top side of the housing 8 away from the first push rod 1. The outer wall of the traction rope 71 passes through the first limiting roller 72 and the second limiting roller 73 in sequence. The bottom end of the traction rope 71 is fixedly connected to a feeding plate 74. Second counterweights are fixedly connected to both sides of the feeding plate 74. A second sliding plate is opened inside the feeding plate 74. A horizontal plate 76 is slidably connected inside the groove 75 and the second slide groove 75.

Specifically, a second light sensor is also installed on one side of the paper feed roller 77. When the paper feed roller 77 is not in contact with the paper, the light sensor does not detect light, and the motor rotates under the control of the control panel 3. Conversely, when the light sensor receives light, the controller stops the motor from rotating.

[0041] A slide rail is provided on the outer wall of the housing 8 near the second counterweight, and the slide rail is slidably connected to the second counterweight. Specifically, a rubber pad is installed in the lower part of the inner wall of the slide rail for cushioning.

[0042] Example 3

[0043] like Figure 1 , 8 As shown, the positioning mechanism 5 includes a thrust rod 51 that is laterally slidably inserted into the lower outer wall of the housing. One end of the thrust rod 51 extends into the interior of the housing 8 and is rotatably equipped with a roller. The roller is in transmission cooperation with the baffle plate 252. A limit sleeve is fixedly connected to the thrust rod 51 on the outer wall inside the housing 8. A second thrust spring is sleeved on the outer wall between the limit sleeve and the housing 8. A pressing rod 55 is rotatably connected to the lower part of the limit sleeve via a pin. A positioning rod 56 is rotatably connected to the lower part of the pressing rod 55 via a pin. A first groove 54 is formed on the outer wall of the housing 8 near the positioning rod 56. One end of the positioning rod 56 is slidably connected to the first groove 54. The positioning rod 56 is located in the first groove 54. A first counterweight 53 is fixedly connected to the bottom side wall of the part. A limiting post 52 is slidably connected to the outer wall of the positioning rod 56 near the first slide groove 54, and the limiting post 52 is fixedly connected to the housing 8. A third thrust spring is sleeved on the outer wall of the limiting post 52 between the positioning rod 56 and the housing 8. Multiple positioning parts are provided on the outer wall of the positioning rod 56 below the stamp. The stamp contacts the surface of the brushing roller 251, so that the surface of the stamp is brushed with oil. At the same time, the blocking plate 252 squeezes the roller, so that the roller squeezes the pressing rod 55 downward. The pressing rod 55 pushes the positioning rod 56 downward, so that the multiple positioning parts on the positioning rod 56 position the paper to be stamped, and prevent it from deviating during the stamping process.

[0044] The positioning component includes a positioning block 57 that is slidably connected to the positioning rod 56. A pressing block is fixedly connected to the bottom end of the positioning block 57. A fourth thrust spring is sleeved on the outer wall of the positioning block 57 between the pressing block and the positioning rod 56. The positioning block 57 limits and fixes the paper to be stamped.

[0045] A control panel 3 is fixedly connected to the outer wall of the housing 8 near the second push rod 21. An inlet 9 is provided on the outer wall below the housing 8. A second light sensor and a pressure sensor are provided on the outer wall of the housing 8 directly below the seal. The second light sensor, the first light sensor, the pressure sensor, and the humidity sensor are all connected to the control panel 3 wirelessly. An outlet 6 is provided on the bottom side wall of the housing 8. The control panel 3 is electrically connected to the first push rod 1, the second push rod 21, the motor, and the liquid pump 26.

[0046] When the paper to be stamped is thick, the first push rod 1 moves the stamp downwards, applying pressure to the paper. The pressure is transmitted to the pressure sensor below the housing 8. When the pressure exceeds the preset protection pressure of the pressure sensor, the pressure sensor sends a signal to the control panel 3, which then controls the height of the first push rod 1 as it descends.

[0047] The working process and principle of this invention are as follows:

[0048] Step 1: First, place the paper to be stamped directly below the housing 8, ensuring the stamping area is below the stamp. The second light sensor does not detect light. Control the first push rod 1 downward via the control panel 3. As the first push rod 1 moves downward, the stamp contacts the surface of the brushing roller 251, causing the stamp surface to be brushed with oil. Simultaneously, the blocking plate 252 presses the roller, causing the roller to press down on the pressing rod 55. The pressing rod 55 pushes the positioning rod 56 downward, allowing several positioning components on the positioning rod 56 to position the paper to be stamped, preventing deviation during the stamping process.

[0049] Step two: At this point, the arc-shaped rod 23 passes through the arc-shaped limiting groove 22 and contacts the outer wall of the oil replenishment tank 241, causing the magnetic block and the magnetic ball 243 to repel each other, pushing the magnetic ball 243 to the middle of the oil replenishment tank 241; then the stamped seal moves upward to... Figure 1 At the position shown, the arc rod 23 is reset due to the action of the first push spring and the first pull spring, which resets the magnetic ball 243. The magnetic block moves up and down with the first push rod 1 and cooperates with the magnetic ball 243, causing the magnetic ball 243 to swing back and forth continuously inside the ink replenishment tank 241, stirring the ink inside the ink replenishment tank 241 and preventing it from settling due to long-term standing, which would cause uneven color distribution inside the ink and affect the later use effect of the ink.

[0050] At the same time, the paper feed roller 77 moves downwards to above the stamped paper due to the gravity of the two second counterweights, and the motor is started, causing the drive shaft 78 to rotate. The drive shaft 78 drives the paper feed roller 77 to rotate, and the stamped paper is sent out through the outlet 6 to the outside of the housing 8. Then the first push rod 1 descends again, and the above steps are repeated to complete the stamping of the remaining paper in sequence until the second light sensor detects the light and the device stops working through the control panel 3.

[0051] Step 3: When the device is not used for a long time, the first push rod 1 moves upward to above the brush wheel 244, and the second push rod 21 pushes the brush wheel 244 on the ink tank 241 to below the stamp, and causes the second push rod 21 to reciprocate to push the ink tank 241. The brush wheel 244 wipes the ink on the outer wall of the stamp to prevent dirt from affecting the color and quality of the ink and the stamp. The ink on the brush wheel 244 is scraped off by the protrusion 246 and enters the interior of the ink tank 241 through the guide plate 247, so that the ink can be reused and the ink is not wasted.
