Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of paper stick surface printing equipment, in particular to a paper stick curved surface quick printing mechanism. Background Art
[0002] At present, people use paper sticks to make cotton swabs, which can be used to clean ears. Generally, the length of the inner ear canal of an adult's ear is 2.5cm-3.5cm, and the length of the inner ear canal of a child's ear is 1cm-1.5cm. However, none of the commonly used cotton swabs has a safe ear cleaning range, so it is difficult for people to grasp the scale when using it. The ear is one of the most fragile human organs, especially when cleaning the ears of children. The ear canal of children is smaller and softer, so you need to be extra careful when cleaning. If you are not careful, the child's ear may be injured. Therefore, it is urgent to produce a cotton swab with a safe ear cleaning range. Utility Model Content
[0003] The problem to be solved by the utility model is to provide a paper stick curved surface quick printing mechanism, which can automatically produce paper sticks with safety rings to meet the needs of the public.
[0004] In order to solve the above technical problems, the technical solutions adopted by the utility model are as follows:
[0005] A paper stick curved surface quick printing mechanism, characterized in that it includes a frame, a friction rolling conveying mechanism, at least one rolling coloring mechanism and a rotation driving unit capable of driving the friction rolling conveying mechanism to rotate, the rotation driving unit is installed on the frame, the friction rolling conveying mechanism is provided with an arcuate channel capable of allowing the paper stick to pass through, the friction rolling conveying mechanism can drive the paper stick to roll forward in the arcuate channel and rotate in a clockwise direction; the rolling coloring mechanism is installed on the frame and is located on one side of the friction rolling conveying mechanism, the rolling coloring mechanism rotates in a clockwise direction, and the lowest point of one end of the paper stick passing through the arcuate channel is in rolling contact with the coloring end of the rolling coloring mechanism.
[0006] The definition of the front and back mentioned above is as follows: based on the conveying direction of the paper stick, the side where the paper stick arrives first is the back, and the side where the paper stick arrives slowly is the front.
[0007] During operation, the arranged paper sticks are transported one by one to the rear end of the friction rolling conveying mechanism through the external feeding mechanism, so that each paper stick enters the arc channel one by one, and under the rotation of the friction rolling conveying mechanism, the paper sticks in the arc channel roll and rub against the inner wall of the arc channel, so that each paper stick can roll forward in the arc channel and roll (rotate) in a clockwise direction; at the same time, the rolling coloring mechanism rotates in a clockwise direction, and the coloring end of the rolling coloring mechanism rolls and contacts with one end of the rotating paper stick, so that the coloring end of the rolling coloring mechanism colors one end of the rotating paper stick, and then prints a safety circle on one end of the paper stick; after printing is completed, each paper stick is transferred out of the arc channel in a counterclockwise direction by the friction rolling conveying mechanism, and the process of quick printing of the curved surface of the paper stick is completed.
[0008] In the preferred embodiment, there are two rolling coloring mechanisms, both of which are mounted on the frame and are located on both sides of the friction rolling conveying mechanism. The lowest points of the two ends of the paper stick in the arc channel are respectively in rolling contact with the coloring ends of the corresponding rolling coloring mechanisms. The two rolling coloring mechanisms rotate in a clockwise direction, and the coloring ends of the two rolling coloring mechanisms are respectively in rolling contact with the two ends of the rotating paper stick, so that the coloring ends of the rolling coloring mechanisms color the two ends of the rotating paper stick in opposite directions, thereby printing a safety circle on the two ends of the paper stick.
[0009] In the preferred embodiment, the rolling coloring mechanism includes a coloring roller, an ink receiving plate and a coloring driving mechanism capable of driving the coloring roller to rotate, the coloring driving mechanism is mounted on the frame, the coloring roller is rotatably mounted on the frame, the coloring roller rotates clockwise, and the radius of the coloring roller is greater than the radius of the paper stick; the ink receiving plate is mounted on the frame and is located below the coloring roller, the ink receiving plate is soaked with ink, the lowest point of the blade of the coloring roller contacts and cooperates with the ink on the ink receiving plate, and the highest point of the blade of the coloring roller contacts and cooperates with the lowest point of the paper stick in the arc channel. Usually, the above-mentioned ink is an environmentally friendly water-based ink. The coloring roller is driven to rotate by the coloring driving mechanism, so that the coloring roller rotates in the opposite direction of the friction rolling conveying mechanism. As long as the surface of the ink receiving plate is fully infiltrated with ink, the lowest point of the blade of the coloring roller will fully contact the ink on the ink receiving plate. As the coloring roller continues to rotate, the entire blade of the coloring roller is stained with ink, and the paper stick rolls and moves forward in a clockwise direction in the arc channel. When the highest point of the blade of the coloring roller contacts and cooperates with the lowest point of the paper stick in the arc channel, the coloring roller colors the paper stick, and the coloring roller just rotates one circle on the paper stick (i.e., just rotates one circle of the circumference of the paper stick), that is, a safety circle is printed at the corresponding position of one end of the paper stick. The above-mentioned coloring driving mechanism can be a driving motor, and the power output shaft of the driving motor is connected to the wheel shaft of the coloring roller, and the driving motor is used to drive the coloring roller to rotate.
[0010] During use, the speed of the coloring roller is adjusted by debugging on the machine, and the speed of the coloring roller is corrected so that the coloring roller prints a safety circle on one end of the rotating paper stick. If the coloring of the paper stick is incomplete (i.e., the end of the paper stick cannot be printed with a safety circle), you only need to increase the speed of the coloring roller through debugging to gradually achieve the coloring of the entire circle of the paper stick.
[0011] In a further preferred embodiment, the rolling coloring mechanism further includes an ink adding mechanism, which includes an ink bottle, an ink guide tube, and a switch valve capable of controlling the flow rate of the ink guide tube. The ink bottle is mounted on the frame and is located above the coloring roller. The ink inlet of the ink guide tube is connected to the ink bottle, and the ink outlet of the ink guide tube extends into the ink receiving plate. The switch valve is mounted on the ink guide tube. Add a proper amount of ink to the ink bottle, and appropriately open the switch valve on the ink guide tube to allow the ink in the ink bottle to flow from top to bottom along the ink guide tube. The ink is dripped into the ink receiving plate through the outlet of the ink guide tube, and the ink is replenished to the ink receiving plate in time, ensuring that the equipment can continuously print a safety circle on the paper stick.
[0012] In a further preferred embodiment, the ink adding mechanism further comprises an ink outlet needle, which is mounted on the ink outlet of the ink guide tube, and the needle of the ink outlet needle extends into the ink receiving plate. Since the needle of the ink outlet needle is small, the amount of ink discharged is very small, and it can better cooperate with the switch valve to control the amount of ink added in the ink receiving plate.
[0013] In the preferred embodiment, the friction rolling conveying mechanism includes a rotating shaft, a rotating wheel and an arc-shaped pressing plate. The two ends of the rotating shaft are rotatably mounted on the frame, and the rotating shaft is connected to the power output end of the rotating drive unit by transmission. The rotating wheel is mounted on the rotating shaft, and the arc-shaped pressing plate is mounted on the frame and is located above the rotating wheel. A rubber ring is sleeved on the rotating wheel, and a film is provided on the inner arc surface of the arc-shaped pressing plate, and the arc-shaped channel is formed between the film and the rubber ring. The arc-shaped pressing plate matches the outer contour of the rotating wheel and forms an arc-shaped channel together, which can effectively guide the paper stick to move along a predetermined path and ensure the stability of the paper stick during movement. The rubber ring on the rotating wheel and the film on the inner arc surface of the arc-shaped pressing plate can increase the friction between the rotating wheel, the arc-shaped pressing plate and the paper stick, which helps to better control the moving speed of the paper stick, so that the paper stick can smoothly enter the arc-shaped channel and roll along the inner wall of the arc-shaped channel, which has a certain shock-absorbing and buffering effect and reduces the scratching of the paper stick during transmission.
[0014] In a preferred embodiment, the paper stick curved surface quick printing mechanism further includes an ink curing mechanism, which includes a support plate and a plurality of ultraviolet curing lamps. The support plate is mounted on the frame and is located above the front of the arc-shaped channel. The rolling coloring mechanism is close to the rear of the arc-shaped channel, and the ultraviolet curing lamps are sequentially mounted on the lower surface of the support plate from the back to the front. The ultraviolet rays emitted by the ultraviolet curing lamps can quickly cure the ink printed on the end of the paper stick, reduce stains or blurring on the paper stick caused by the ink not being dry, thereby improving the printing quality of the paper stick and improving production efficiency in a continuous production environment.
[0015] In a further preferred embodiment, the support plate is an arc-shaped plate, and the arc-shaped plate extends above the rotation track of the friction rolling conveying mechanism. The design of the arc-shaped plate can match the arc-shaped channel of the friction rolling conveying mechanism, ensuring that the ultraviolet curing lamp can evenly irradiate the entire surface of the paper stick, especially the safety ring part at the end of the paper stick.
[0016] Usually, the above-mentioned rotation driving unit includes a driving motor, a plurality of synchronous chains and a plurality of synchronous wheels. The driving motor is fixedly mounted on the frame, a synchronous wheel is mounted on the power output shaft of the driving motor, another synchronous wheel is mounted on the first rotating shaft, another synchronous wheel is mounted on the rotating shaft, and each synchronous chain is tensioned outside the corresponding synchronous wheel. The driving motor drives a synchronous wheel to rotate, and then the first rotating shaft and the rotating shaft are rotated under the drive of each synchronous chain. In the synchronous chain transmission system, different rotation speeds of different components are achieved by changing the diameter of the synchronous wheel.
[0017] Compared with the prior art, the utility model has the following advantages:
[0018] (1) The utility model colors the two ends of each paper stick to form a safety ring with a safety reminder function. When using the paper stick, the user can accurately judge the safe ear cleaning range according to the position of the safety ring, thereby reducing the risk of accidental ear injury, which is especially safer for children.
[0019] (2) The utility model ensures that each paper stick can be evenly colored to form an obvious safety mark by accurately controlling the direction and rotation speed of the friction rolling conveying mechanism and the direction and rotation speed of the rolling coloring mechanism, thereby improving the quality and consistency of the product; and can adapt to paper sticks of different lengths and diameters, with strong flexibility and adaptability to meet the production needs of different products.

[0022] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0023] like Figure 1-2 As shown, the paper stick curved surface quick printing mechanism in this embodiment includes a frame (not shown in the figure), a friction rolling conveying mechanism 1, at least one rolling coloring mechanism 2 and a rotation driving unit (not shown in the figure) capable of driving the friction rolling conveying mechanism 1 to rotate, the rotation driving unit is mounted on the frame, the friction rolling conveying mechanism 1 is provided with an arcuate channel 11 capable of allowing the paper stick 3 to pass through, the friction rolling conveying mechanism 1 can drive the paper stick 3 to roll forward in the arcuate channel 11 and rotate in a clockwise direction; the rolling coloring mechanism 2 is mounted on the frame and is located on one side of the friction rolling conveying mechanism 1, the rotation direction of the rolling coloring mechanism 2 is clockwise, and the lowest point of one end of the paper stick 3 passing through the arcuate channel 11 is in rolling contact with the coloring end of the rolling coloring mechanism 2.
[0024] The definition of the front and the back is as follows: based on the conveying direction of the paper stick 3, the side where the paper stick 3 arrives first is the back, and the side where the paper stick 3 arrives slowly is the front.
[0025] During operation, the arranged paper sticks 3 are transported one by one to the rear end of the friction rolling conveying mechanism 1 through the external feeding mechanism 5, so that each paper stick 3 enters the arc channel 11 one by one, and under the rotation of the friction rolling conveying mechanism 1, the paper sticks 3 in the arc channel 11 roll and rub against the inner wall of the arc channel 11, so that each paper stick 3 can roll forward in the arc channel 11 and roll (rotate) in a clockwise direction; at the same time, the rolling coloring mechanism 2 rotates in a clockwise direction, and the coloring end of the rolling coloring mechanism 2 rolls and contacts with one end of the rotating paper stick 3, so that the coloring end of the rolling coloring mechanism 2 colors one end of the rotating paper stick 3, and then a safety circle 31 is printed on one end of the paper stick 3; after printing is completed, each paper stick 3 is transferred out of the arc channel 11 by the friction rolling conveying mechanism 1 in a counterclockwise direction, that is, the process of curved surface rapid printing of the paper stick 3 is completed.
[0026] There are two rolling coloring mechanisms 2, both of which are mounted on the frame and are located on both sides of the friction rolling conveying mechanism 1. The lowest points of the two ends of the paper stick 3 in the arc-shaped channel 11 are respectively in rolling contact with the coloring ends of the corresponding rolling coloring mechanisms 2. The two rolling coloring mechanisms 2 rotate in a clockwise direction, and the coloring ends of the two rolling coloring mechanisms 2 are respectively in rolling contact with the two ends of the rotating paper stick 3, so that the coloring ends of the rolling coloring mechanisms 2 are oppositely colored to the two ends of the rotating paper stick 3, and then a safety circle 31 is printed on the two ends of the paper stick 3.
[0027] The rolling coloring mechanism 2 includes a coloring roller 21, an ink receiving plate 22 and a coloring driving mechanism (not shown) capable of driving the coloring roller 21 to rotate. The coloring driving mechanism is mounted on the frame, and the coloring roller 21 is rotatably mounted on the frame. The coloring roller 21 rotates clockwise, and the radius of the coloring roller 21 is greater than the radius of the paper stick 3. The ink receiving plate 22 is mounted on the frame and is located below the coloring roller 21. The ink receiving plate 22 is soaked with ink. The lowest point of the blade 211 of the coloring roller 21 contacts and cooperates with the ink on the ink receiving plate 22, and the highest point of the blade 211 of the coloring roller 21 contacts and cooperates with the lowest point of the paper stick 3 in the arc channel 11. Usually, the above-mentioned ink is an environmentally friendly water-based ink. The coloring roller 21 is driven to rotate by the coloring driving mechanism so that the coloring roller 21 rotates in the opposite direction of the friction rolling conveying mechanism 1. As long as the surface of the ink receiving plate 22 is fully infiltrated with ink, the lowest point of the blade 211 of the coloring roller 21 will be in full contact with the ink on the ink receiving plate 22. As the coloring roller 21 continues to rotate, the blade 211 of the entire coloring roller 21 is stained with ink, and the paper stick 3 rolls and moves forward in the arc channel 11 in a clockwise direction. When the highest point of the blade 211 of the coloring roller 21 contacts and cooperates with the lowest point of the paper stick 3 in the arc channel 11, the coloring roller 21 colors the paper stick 3 upward, and the coloring roller 21 just rotates once on the paper stick 3 (that is, just rotates once the circumference of the paper stick 3), that is, a safety circle is printed at the corresponding position at one end of the paper stick 3. The coloring driving mechanism may be a driving motor, the power output shaft of the driving motor is drivingly connected to the axle of the coloring roller 21, and the coloring roller 21 is driven to rotate by the driving motor.
[0028] During use, the rotation speed of the coloring roller 21 is adjusted by debugging on the machine, and the rotation speed of the coloring roller 21 is corrected so that the coloring roller 21 prints a safety circle on one end of the rotating paper stick 3. If the coloring of the paper stick 3 is incomplete (i.e., the end of the paper stick 3 cannot be printed with a safety circle), the rotation speed of the coloring roller 21 can be increased by debugging to gradually realize the coloring of the entire circle of the paper stick 3.
[0029] The rolling coloring mechanism 2 also includes an ink adding mechanism 23, which includes an ink bottle 231, an ink guide tube 232, and a switch valve 233 capable of controlling the flow rate of the ink guide tube 232. The ink bottle 231 is installed on the frame and is located above the coloring roller 21. The ink inlet of the ink guide tube 232 is connected to the ink bottle 231, and the ink outlet of the ink guide tube 232 extends into the ink receiving plate 22. The switch valve 233 is installed on the ink guide tube 232. Add a proper amount of ink to the ink bottle 231, and appropriately open the switch valve 233 on the ink guide tube 232, so that the ink in the ink bottle 231 flows from top to bottom along the ink guide tube 232, and the ink is dripped into the ink receiving plate 22 through the outlet of the ink guide tube 232, so that the ink receiving plate 22 is replenished with ink in time, and the device can continuously print the safety ring on the paper stick 3.
[0030] The ink adding mechanism 23 further includes an ink outlet needle 234, which is installed on the ink outlet of the ink guide tube 232, and the needle of the ink outlet needle 234 extends into the ink receiving plate 22. Since the needle of the ink outlet needle 234 is small, the amount of ink discharged is very small, which can better cooperate with the switch valve 233 to control the amount of ink added in the ink receiving plate 22.
[0031] The friction rolling conveying mechanism 1 comprises a rotating shaft 12, a rotating wheel 13 and an arc-shaped pressing plate 14. The two ends of the rotating shaft 12 are rotatably mounted on the frame, and the rotating shaft 12 is drivingly connected with the power output end of the rotating drive unit. The rotating wheel 13 is mounted on the rotating shaft 12, and the arc-shaped pressing plate 14 is mounted on the frame and is located above the rotating wheel 13. A rubber ring 15 is sleeved on the rotating wheel 13, and a film 16 is provided on the inner arc surface of the arc-shaped pressing plate 14. The arc-shaped channel 11 is formed between the film 16 and the rubber ring 15. The arc-shaped pressing plate 14 matches the outer contour of the rotating wheel 13 and forms the arc-shaped channel 11 together, which can effectively guide the paper stick 3 to move along a predetermined path and ensure the stability of the paper stick 3 during the movement. The rubber ring 15 on the rotating wheel 13 and the film 16 on the inner arc surface of the arc pressure plate 14 can increase the friction between the rotating wheel 13, the arc pressure plate 14 and the paper stick 3, which helps to better control the moving speed of the paper stick 3, so that the paper stick 3 can smoothly enter the arc channel 11 and roll along the inner wall of the arc channel 11, which has a certain shock-absorbing and buffering effect, and reduces the scratching of the paper stick 3 during the transmission process.
[0032] The paper stick curved surface quick printing mechanism also includes an ink curing mechanism 4, which includes a support plate 41 and a plurality of ultraviolet curing lamps 42. The support plate 41 is mounted on the frame and is located above the front of the arc-shaped channel 11. The rolling coloring mechanism 2 is close to the rear of the arc-shaped channel 11, and each ultraviolet curing lamp 42 is sequentially mounted on the lower surface of the support plate 41 from the back to the front. The ultraviolet rays emitted by each ultraviolet curing lamp 42 can quickly cure the ink printed on the end of the paper stick 3, reduce stains or blurring on the paper stick 3 due to the ink not being dry, thereby improving the printing quality of the paper stick 3 and improving production efficiency in a continuous production environment.
[0033] The support plate 41 is an arc-shaped plate, and the arc-shaped plate extends above the rotation track of the friction rolling conveying mechanism 1. The design of the arc-shaped plate can match the arc-shaped channel 11 of the friction rolling conveying mechanism 1, ensuring that the ultraviolet curing lamp 42 can evenly irradiate the entire surface of the paper stick 3, especially the safety ring part at the end of the paper stick 3.
