Description

Technical Field

[0001] The present invention belongs to the technical field of label printing, and particularly relates to a device for adjusting the spacing for self-adhesive label printing. Background Art

[0002] Label printing refers to the process of printing labels on paper, film, plastic film or other materials. Labels are usually used in product packaging, logistics identification, product identification, price labels and other aspects.

[0003] Existing labels need to divide the label paper tape into two parts during printing, and then overlap and press the two groups of label paper tapes. Most existing equipment overlaps the two groups of label paper tapes again after splitting during production, and then performs the pressing operation, resulting in the inability to quickly overlap the two groups of label paper tapes, increasing cumbersome procedures and reducing the processing efficiency of the label paper tape. Summary of the Invention

[0004] The purpose of the present invention is to provide a device for adjusting the spacing for self-adhesive label printing, aiming to solve the technical problem in the prior art that the two groups of label paper tapes cannot be quickly overlapped, reducing the processing efficiency of the label paper tape.

[0005] The present invention is realized as follows. A device for adjusting the spacing for self-adhesive label printing includes a frame. A plurality of auxiliary rollers at different positions are rotatably installed on the frame. A substrate is fixedly installed on the side of the frame. A rotating frame is rotatably installed on the substrate, and a rotating power member for driving the rotating frame to rotate is fixedly installed on the substrate. A feeding cylinder is fixedly installed on the rotating frame. One end of the feeding cylinder is of an open structure, and a cover plate for closing the feeding cylinder is fixedly installed at one end of the rotating frame through screws. A plurality of through holes are formed in the cover plate and the area of the rotating frame corresponding to the feeding cylinder, and heat dissipation fans are fixedly installed in the through holes. A plurality of first mounting rods are fixedly installed in the feeding cylinder. The first mounting rods are distributed along the length direction of the feeding cylinder. A support plate is slidably installed on the first mounting rods. A first servo module for driving the support plate to move is arranged in the feeding cylinder. An installation ring is fixedly installed on the support plate. The installation ring is coaxially arranged with the feeding cylinder. A plurality of support rods are slidably installed on the installation ring. The support rods are distributed along the radial direction of the installation ring. A heat dissipation plate is fixedly installed at the end of the support rod away from the support plate. A plurality of heat dissipation fins are fixedly installed on the surface of the heat dissipation plate close to the installation ring. A telescopic member for driving the plurality of support rods to move simultaneously is fixedly installed on the support plate.

[0006] Further technical solution: The heat dissipation plate is arc-shaped and the heat dissipation plate is in contact with the inner wall of the feeding cylinder and the two are in fit.

[0007] Further technical solution: The telescopic member is distributed along the length direction of the material feeding cylinder, and a connecting ring is fixedly installed at its output end. A plurality of power brackets are fixedly installed on the connecting ring. The power brackets are right-angled triangles, and the positions of the power brackets correspond to the support rods. The inclined section of the power bracket is slidably connected to the corresponding support rod.

[0008] Further technical solution: A groove is formed on the surface of the heat dissipation plate away from the mounting ring, and an oil-absorbing sponge is fixedly installed in the groove. A cross plate is fixedly installed on the support plate, and an oil tank and a two-way oil pump are fixedly installed on the cross plate. The oil tank is connected to the two-way oil pump, and the two-way oil pump is communicated with the groove where the oil-absorbing sponge is located.

[0009] Further technical solution: The two-way oil pump is communicated with an oil supply ring fixedly installed on the cross plate through a pipeline. The oil supply ring is arranged coaxially with the material feeding cylinder. A plurality of uniformly distributed oil supply pipes are communicated with the oil supply ring. A plurality of hoses are communicated with the oil supply pipes. The hoses are respectively communicated with the grooves on two adjacent heat dissipation plates to the oil supply pipes, and the hoses are communicated with both sides of the grooves.

[0010] Further technical solution: A second mounting rod is fixedly installed in the material feeding cylinder. A scraping ring is slidably installed on the second mounting rod. The scraping ring is in sliding contact with the inner wall of the material feeding cylinder. A second servo module for driving the scraping ring to move is arranged in the material feeding cylinder.

[0011] Further technical solution: A plurality of arc-shaped closing plates are fixedly installed on the scraping ring. The positions of the closing plates correspond to the heat dissipation plates, and the closing plates are used to close the grooves on the heat dissipation plates.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The label paper tape passes upward through the auxiliary roller and then winds around the material feeding cylinder. Since the material feeding cylinder is in an inclined state, the label paper tape will shift in the direction of the higher end of the material feeding cylinder after winding around the material feeding cylinder once, so that the higher end of the material feeding cylinder is located on the side where the label paper tape that keeps horizontal movement is located. According to the width of the paper tape after slitting, adjusting the inclination angle of the material feeding cylinder can adjust the offset width of the label paper tape, so that the projection of the label paper tape on the horizontal plane after offset coincides with the label paper tape moving horizontally below. Then it passes through the auxiliary roller downward again and becomes a state of parallel movement with the first group of label paper tapes, which is convenient for subsequent pressing of the two groups of label paper tapes again, realizing the rapid adjustment of the position of the label paper tape and ensuring that the label paper tape is in a rapid movement state, improving the processing efficiency of the label paper tape.

[0013] 2. During use, according to the position where the label paper tape contacts the material feeding cylinder, the support plate is driven by the first servo module to move to this position. Then, the telescopic member drives the heat dissipation plate to contact the inner wall of the material feeding cylinder. At the same time, the heat dissipation fans at both ends of the material feeding cylinder are turned on, and the air in the material feeding cylinder flows from the lower end to the higher end through the heat dissipation fans. The air flow quickly cools the heat dissipation plate through the heat dissipation fins, thereby improving the heat dissipation effect of the material feeding cylinder, achieving efficient cooling of the contact position between the material feeding cylinder and the label paper tape, avoiding the influence of overheating of the material feeding cylinder on the label paper tape, and ensuring the production quality of the label paper tape.

[0014] 3. When the heat dissipation plate contacts the inner wall of the material feeding cylinder, at this time, the groove is the distribution space. The cooling oil in the fuel tank is pumped by the two-way oil pump, and then transported to the groove through the oil supply ring, oil supply pipe and hose until the groove is filled with cooling oil and then stopped. By contacting the cooling oil with the inner wall of the material feeding cylinder, seamless contact with the inner wall of the material feeding cylinder is achieved, reducing the gap when the heat dissipation plate contacts the inner wall of the material feeding cylinder, further improving the efficiency of heat transfer from the inner wall of the material feeding cylinder to the heat dissipation plate, and further improving the heat dissipation effect.

[0015] 4. When not in use, the groove on the heat dissipation plate is closed by the closing plate, thereby preventing the cooling oil in the groove with the opening facing down from flowing downward through the oil absorption sponge, avoiding leakage of the cooling oil, keeping the inside of the material feeding cylinder clean, and then reducing the residue of impurities on the inner wall of the material feeding cylinder. When used again later, the second servo module drives the scraping ring to move to clean the inner wall of the material feeding cylinder through the scraping ring, and then the heat dissipation plate is made to contact the inner wall of the material feeding cylinder, avoiding the presence of impurities at the contact position between the heat dissipation plate and the inner wall of the material feeding cylinder, ensuring the sealing performance of the contact between the heat dissipation plate and the inner wall of the material feeding cylinder, and further improving the heat dissipation capacity.

Detailed implementation manners

[0028] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0029] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.

[0030] As Figures 1-11 shown, a device for adjusting the spacing for printing self-adhesive labels provided by the present invention includes a frame 1, on which a plurality of auxiliary rollers located at different positions are rotatably installed. A base plate 2 is fixedly installed on the side of the frame 1. A rotating frame 3 is rotatably installed on the base plate 2, and a rotating power member 4 for driving the rotating frame 3 to rotate is fixedly installed on the base plate 2. A feeding cylinder 5 is fixedly installed on the rotating frame 3. One end of the feeding cylinder 5 is an open structure, and a cover plate 6 for closing the feeding cylinder 5 is fixedly installed at one end of the rotating frame 3 by screws. A plurality of through holes 7 are formed in the areas of the cover plate 6 and the rotating frame 3 corresponding to the feeding cylinder 5, and heat dissipation fans 8 are fixedly installed in the through holes 7; A plurality of first mounting rods 9 are fixedly installed inside the material feeding cylinder 5. The first mounting rods 9 are distributed along the length direction of the material feeding cylinder 5. A support plate 11 is slidably installed on the first mounting rods 9. A first servo module 10 for driving the support plate 11 to move is arranged inside the material feeding cylinder 5. An installation ring 12 is fixedly installed on the support plate 11. The installation ring 12 is coaxially arranged with the material feeding cylinder 5. A plurality of support rods 16 are slidably installed on the installation ring 12. The support rods 16 are distributed along the radial direction of the installation ring 12. A heat dissipation plate 17 is fixedly installed at one end of the support rod 16 away from the support plate 11. A plurality of heat dissipation fins 18 are fixedly installed on the surface of the heat dissipation plate 17 close to the installation ring 12. The heat dissipation plate 17 is arc-shaped and fits with the inner wall of the material feeding cylinder 5 when they contact. A telescopic member 13 for driving a plurality of support rods 16 to move simultaneously is fixedly installed on the support plate 11. The telescopic member 13 is distributed along the length direction of the material feeding cylinder 5 and its output end is fixedly installed with a connection ring 14. A plurality of power brackets 15 are fixedly installed on the connection ring 14. The power brackets 15 are right-angled triangles and the positions of the power brackets 15 correspond to the support rods 16. The inclined section of the power bracket 15 is slidably connected to the corresponding support rod 16.

[0031] In practical application of this embodiment, according to the width of the label paper tape, the rotating power member 4 is rotated to drive the rotating frame 3 to rotate. The rotating frame 3 drives the material feeding cylinder 5 to rotate to an inclined state. The label paper tape is cut in half from the middle and then enters the frame 1 from below. The transparent protective film on the label paper tape is separated and guided upward through the auxiliary roller and then wound by the winding mechanism. After the label paper tape is cut in half, one group of label paper tapes continues to move forward, and the other group of label paper tapes moves upward through the auxiliary roller and then winds around the material feeding cylinder 5. Since the material feeding cylinder 5 is in an inclined state, the label paper tape will shift in the direction of the higher end of the material feeding cylinder 5 after winding around the material feeding cylinder 5 for one circle, so that the higher end of the material feeding cylinder 5 is located on the side where the label paper tape that keeps horizontal movement is located. According to the width of the paper tape after cutting, the inclination angle of the material feeding cylinder 5 can be adjusted to adjust the offset width of the label paper tape, so that the projection of the label paper tape on the horizontal plane after offset coincides with the label paper tape that moves horizontally below. Then, it moves downward through the auxiliary roller again and becomes a state of moving parallel to the first group of label paper tapes, which is convenient for subsequent pressing of the two groups of label paper tapes again, realizing the rapid adjustment of the position of the label paper tape and ensuring that the label paper tape is in a rapid moving state, improving the processing efficiency of the label paper tape; During use, according to the position where the label paper tape contacts the feeding cylinder 5, the support plate 11 is driven by the first servo module 10 to move to this position. Then, the telescopic member 13 contracts to drive the connecting ring 14 to move towards the support plate 11. Furthermore, through the power frame 15, the support rod 16 can be pushed to move away from the support plate 11 until the heat dissipation plate 17 abuts against the inner wall of the feeding cylinder 5. At the same time, the heat dissipation fans 8 at both ends of the feeding cylinder 5 are turned on, and the air in the feeding cylinder 5 is made to flow from the lower end to the higher end by the heat dissipation fans 8. The air flow quickly cools the heat dissipation plate 17 through the heat dissipation fins 18, thereby improving the heat dissipation effect of the feeding cylinder 5, achieving efficient cooling of the contact position between the feeding cylinder 5 and the label paper tape, avoiding the influence of overheating of the feeding cylinder 5 on the label paper tape, and ensuring the production quality of the label paper tape.

[0032] In an example of this embodiment, the telescopic member 13 is an electric telescopic rod. Of course, it can also be other components such as a hydraulic cylinder that can actively change in length, and the heat dissipation plate 17 is driven by the electric telescopic rod.

[0033] As Figures 6-9 shown, a device for adjusting the spacing for printing self-adhesive labels provided by the present invention, a groove is provided on the surface of the heat dissipation plate 17 away from the mounting ring 12, and an oil-absorbing sponge 19 is fixedly installed in the groove. A cross plate 20 is fixedly installed on the support plate 11, and an oil tank 21 and a two-way oil pump 22 are fixedly installed on the cross plate 20. The oil tank 21 is connected to the two-way oil pump 22, and the two-way oil pump 22 communicates with the groove where the oil-absorbing sponge 19 is located.

[0034] Specifically, the two-way oil pump 22 is connected to an oil supply ring 23 fixedly installed on the cross plate 20 through a pipeline. The oil supply ring 23 is coaxially arranged with the feeding cylinder 5. A plurality of uniformly distributed oil supply pipes 24 are communicated with the oil supply ring 23. A plurality of hoses 25 are communicated with the oil supply pipes 24. The hoses 25 are respectively communicated with the grooves on two adjacent heat dissipation plates 17 of the oil supply pipes 24, and the hoses 25 are communicated with both sides of the grooves.

[0035] When this embodiment is actually applied, when the heat dissipation plate 17 contacts the inner wall of the feeding cylinder 5, at this time, the groove is the distribution space. The two-way oil pump 22 extracts the cooling oil in the oil tank 21, and then transports it to the groove through the oil supply ring 23, the oil supply pipes 24 and the hoses 25 until the groove is filled with cooling oil and then stops. By making the cooling oil contact the inner wall of the feeding cylinder 5, seamless contact with the inner wall of the feeding cylinder 5 is achieved, reducing the gap when the heat dissipation plate 17 contacts the inner wall of the feeding cylinder 5, further improving the efficiency of heat transfer from the inner wall of the feeding cylinder 5 to the heat dissipation plate 17, and further improving the heat dissipation effect; When it is not used subsequently, the two-way oil pump 22 reversely extracts the cooling oil in the groove and conveys it into the fuel tank 21. The cooling oil in the oil-absorbing sponge 19 flows downward under the action of gravity and is extracted. After extracting for a set time, the extraction stops. At this time, a small amount of cooling oil remains in the oil-absorbing sponge 19. At this time, the heat dissipation plate 17 is separated from the material feeding cylinder 5.

[0036] As Figure 5 , Figure 10 shown, a spacing adjusting device for adhesive label printing provided by the present invention. A second mounting rod 26 is fixedly installed in the material feeding cylinder 5. A scraping ring 27 is slidably installed on the second mounting rod 26. The scraping ring 27 is in sliding contact with the inner wall of the material feeding cylinder 5. A second servo module 28 for driving the scraping ring 27 to move is arranged in the material feeding cylinder 5.

[0037] Specifically, a plurality of arc-shaped closing plates 29 are fixedly installed on the scraping ring 27. The positions of the closing plates 29 correspond to the heat dissipation plate 17 and the closing plates 29 are used to close the grooves on the heat dissipation plate 17.

[0038] In actual application of this embodiment, when the heat dissipation plate 17 is separated from the material feeding cylinder 5, the second servo module 28 drives the scraping ring 27 to move so that the closing plate 29 moves to the position where the heat dissipation plate 17 is located. The grooves on the heat dissipation plate 17 are closed by the closing plate 29, so as to prevent the cooling oil in the groove with the opening facing downward from flowing downward from the oil-absorbing sponge 19, avoid the leakage of the cooling oil, keep the inside of the material feeding cylinder 5 clean, and further reduce the residue of impurities on the inner wall of the material feeding cylinder 5. When used again subsequently, the second servo module 28 drives the scraping ring 27 to move to clean the inner wall of the material feeding cylinder 5 through the scraping ring 27, and then makes the heat dissipation plate 17 contact with the inner wall of the material feeding cylinder 5, avoiding the existence of impurities at the contact position between the heat dissipation plate 17 and the inner wall of the material feeding cylinder 5, ensuring the sealing performance of the contact between the heat dissipation plate 17 and the inner wall of the material feeding cylinder 5, and further improving the heat dissipation capacity.

[0039] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

[0040] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
