Description

Technical Field

[0001] The invention belongs to the technical field of label printing, and in particular relates to a spacing adjustment device 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 commonly used in product packaging, logistics identification, product identification, price tags, etc.

[0003] When printing existing labels, the label paper tape needs to be divided into two groups, and then the two groups of label paper tapes are overlapped and pressed together. During production, the existing equipment mostly overlaps the two groups of label paper tapes again after the division is completed, and then performs the pressing operation, which makes it impossible to overlap the two groups of label paper tapes quickly, increases the cumbersome process, and reduces the processing efficiency of the label paper tapes. Summary of the Invention

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

[0006] Multiple groups of first mounting rods are fixedly installed in the feeding barrel, and the first mounting rods are distributed along the length direction of the feeding barrel. A support plate is slidably installed on the first mounting rod, and a first servo module is provided in the feeding barrel to drive the support plate to move. A mounting ring is fixedly installed on the support plate, and the mounting ring is coaxially arranged with the feeding barrel. Multiple groups of support rods are slidably installed on the mounting ring, and the support rods are distributed radially along the mounting ring. A heat sink is fixedly installed on one end of the support rod away from the support plate, and multiple groups of heat dissipating fins are fixedly installed on the surface of the heat sink close to the mounting ring, and a telescopic part that drives multiple groups of support rods to move simultaneously is fixedly installed on the support plate.

[0007] Further technical solution: the heat dissipation plate is arc-shaped and when the heat dissipation plate contacts the inner wall of the feeding barrel, the two are in contact with each other.

[0008] Further technical solution: the telescopic parts are distributed along the length direction of the feeding barrel and a connecting ring is fixedly installed at its output end, and multiple groups of power frames are fixedly installed on the connecting ring. The power frame is a right triangle and the position of the power frame corresponds to the support rod. The inclined section of the power frame is slidably connected to the corresponding support rod.

[0009] Further technical solution: a groove is provided on the surface of the heat sink away from the mounting ring and an oil-absorbing sponge is fixedly installed in the groove, a horizontal plate is fixedly installed on the support plate, an oil tank and a two-way oil pump are fixedly installed on the horizontal plate, the oil tank is connected to the two-way oil pump, and the groove where the oil-absorbing sponge of the two-way oil pump is located is connected.

[0010] Further technical solution: The bidirectional oil pump is connected to the oil supply ring fixedly installed on the horizontal plate through a pipeline. The oil supply ring is coaxially arranged with the feeding barrel. The oil supply ring is connected to multiple groups of evenly distributed oil supply pipes. The oil supply pipes are connected to multiple groups of hoses. The hoses are respectively connected to the grooves on the two groups of heat dissipation plates adjacent to the oil supply pipes, and the hoses are connected to both sides of the grooves.

[0011] Further technical solution: A second mounting rod is fixedly installed in the feeding barrel, a scraper ring is slidably installed on the second mounting rod, the scraper ring is in sliding contact with the inner wall of the feeding barrel, and a second servo module is provided in the feeding barrel to drive the scraper ring to move.

[0012] Further technical solution: a plurality of groups of arc-shaped closing plates are fixedly mounted on the scraper 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.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The label paper tape passes upward through the auxiliary roller and then wraps around the feed roller. Since the feed roller is in an inclined state, the label paper tape will deviate toward the direction of the higher end of the feed roller after wrapping around the feed roller, so that the higher end of the feed roller is located on the side where the label paper tape that keeps moving horizontally is located. According to the width of the paper tape after slitting, the offset width of the label paper tape can be adjusted by adjusting the inclination angle of the feed roller, so that the projection of the label paper tape to the horizontal plane after deflection coincides with the label paper tape moving horizontally below. After that, it passes through the auxiliary roller again and moves downward and becomes parallel to the first set of label paper tapes, which facilitates the subsequent pressing of the two sets of label paper tapes. This realizes the rapid adjustment of the position of the label paper tape and can ensure that the label paper tape is in a fast-moving state, thereby improving the processing efficiency of the label paper tape.

[0015] 2. When in use, according to the position where the label paper tape contacts the feed barrel, the first servo module drives the support plate to move to that position, and then the telescopic part drives the heat sink to contact the inner wall of the feed barrel, and at the same time, the cooling fans at both ends of the feed barrel are turned on. The cooling fans make the air in the feed barrel flow from the lower end to the higher end, and the air flows through the cooling fins to quickly cool down the heat sink, thereby improving the heat dissipation effect of the feed barrel, achieving efficient cooling of the contact position between the feed barrel and the label paper tape, avoiding the impact of overheating of the feed barrel on the label paper tape, and ensuring the production quality of the label paper tape.

[0016] 3. When the heat sink contacts the inner wall of the barrel, the groove becomes a distribution space. The cooling oil in the oil tank is extracted by a two-way oil pump, and then delivered to the groove through the oil supply ring, oil supply pipe and hose until the groove is filled with cooling oil. The cooling oil contacts the inner wall of the barrel, achieving seamless contact with the inner wall of the barrel, reducing the gap when the heat sink contacts the inner wall of the barrel, further improving the efficiency of heat transfer from the inner wall of the barrel to the heat sink, and further improving the heat dissipation effect.

[0017] 4. When not in use, the groove on the heat sink is closed by a closing plate to prevent the cooling oil in the groove with the opening facing downward from flowing downward from the oil-absorbing sponge, thereby preventing leakage of cooling oil, keeping the inside of the barrel clean, and reducing the residual impurities on the inner wall of the barrel. When used again later, the second servo module drives the scraper ring to move to clean the inner wall of the barrel, and then the heat sink is brought into contact with the inner wall of the barrel to avoid the presence of impurities at the contact position between the heat sink and the inner wall of the barrel, thereby ensuring the sealing of the contact between the heat sink and the inner wall of the barrel, and further improving the heat dissipation capacity.

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0031] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0032] like Figures 1-11 As shown, a spacing adjustment device for printing self-adhesive labels provided by the present invention comprises a frame 1, on which multiple groups of auxiliary rollers located at different positions are rotatably mounted, a base plate 2 is fixedly mounted on the side of the frame 1, a rotating frame 3 is rotatably mounted on the base plate 2, and a rotating power member 4 for driving the rotating frame 3 to rotate is fixedly mounted on the base plate 2, a feeding cylinder 5 is fixedly mounted 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 mounted on one end of the rotating frame 3 by screws, multiple groups of through holes 7 are formed on the cover plate 6 and the area on the rotating frame 3 corresponding to the feeding cylinder 5, and a cooling fan 8 is fixedly mounted in the through hole 7;

[0033] Multiple groups of first mounting rods 9 are fixedly installed in the feeding barrel 5, and the first mounting rods 9 are distributed along the length direction of the feeding barrel 5. A support plate 11 is slidably installed on the first mounting rod 9. A first servo module 10 that drives the support plate 11 to move is provided in the feeding barrel 5. A mounting ring 12 is fixedly installed on the support plate 11. The mounting ring 12 is coaxially arranged with the feeding barrel 5. Multiple groups of support rods 16 are slidably installed on the mounting ring 12. The support rods 16 are distributed along the radial direction of the mounting ring 12. A heat sink 17 is fixedly installed on the end of the support rod 16 away from the support plate 11. The heat sink 17 is close to the mounting plate A plurality of heat dissipation fins 18 are fixedly mounted on the surface of the mounting ring 12. The heat dissipation plate 17 is arc-shaped and the heat dissipation plate 17 fits in contact with the inner wall of the feeding barrel 5. A telescopic member 13 is fixedly mounted on the support plate 11 to drive a plurality of support rods 16 to move simultaneously. The telescopic member 13 is distributed along the length direction of the feeding barrel 5 and a connecting ring 14 is fixedly mounted on the output end thereof. A plurality of power frames 15 are fixedly mounted on the connecting ring 14. The power frame 15 is a right triangle and the position of the power frame 15 corresponds to the support rod 16. The inclined section of the power frame 15 is slidably connected to the corresponding support rod 16.

[0034] In actual application, according to the width of the label paper tape, the rotating frame 3 is driven to rotate by the rotating power member 4, and the rotating frame 3 drives the feeding drum 5 to rotate to an inclined state. After the label paper tape is cut into two parts from the middle, it enters the frame 1 from the bottom. 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 divided into two, one group of label paper tapes continues to move forward, and the other group of label paper tapes passes through the auxiliary roller upward and then goes around the feeding drum 5. Since the feeding drum 5 is in an inclined state, the label paper tape will move towards the feeding drum 5 after going around the feeding drum 5 once. The direction of the higher end is offset, so that the higher end of the feeding drum 5 is located on the side where the label paper tape is kept moving horizontally. According to the width of the paper tape after slitting, the offset width of the label paper tape can be adjusted by adjusting the inclination angle of the feeding drum 5, so that the projection of the label paper tape to the horizontal plane after offset coincides with the label paper tape moving horizontally below, and then moves downward again through the auxiliary roller and becomes a state of moving parallel to the first set of label paper tapes, which is convenient for the subsequent pressing of the two sets of label paper tapes, realizes the rapid adjustment of the position of the label paper tape and can ensure that the label paper tape is in a fast moving state, thereby improving the processing efficiency of the label paper tape;

[0035] When in use, the support plate 11 is driven to move to the position according to the contact position of the label paper tape and the feed barrel 5 through the first servo module 10, and then the telescopic member 13 contracts to drive the connecting ring 14 to move in the direction close to the support plate 11, and then the power frame 15 can push the support rod 16 to move in the direction away from the support plate 11 until the heat sink 17 contacts the inner wall of the feed barrel 5, and at the same time, the cooling fans 8 at both ends of the feed barrel 5 are turned on. The cooling fans 8 make the air in the feed barrel 5 flow from the lower end to the higher end, and the air flows through the heat dissipation fins 18 to quickly cool down the heat sink 17, thereby improving the heat dissipation effect of the feed barrel 5, achieving efficient cooling of the contact position between the feed barrel 5 and the label paper tape, avoiding the overheating of the feed barrel 5 and affecting the label paper tape, and ensuring the production quality of the label paper tape.

[0036] In an example of this embodiment, the telescopic member 13 is an electric telescopic rod, and of course it can also be other components that can actively change the length, such as a hydraulic cylinder, and the heat dissipation plate 17 is driven to move by the electric telescopic rod.

[0037] like Figure 6-Figure 9 As shown, a spacing adjustment device for self-adhesive label printing provided by the present invention is provided. A groove is provided on the surface of the heat sink 17 away from the mounting ring 12, and an oil-absorbing sponge 19 is fixedly installed in the groove. A horizontal 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 horizontal plate 20. The oil tank 21 is connected to the two-way oil pump 22, and the two-way oil pump 22 is connected to the groove where the oil-absorbing sponge 19 is located.

[0038] Specifically, the bidirectional oil pump 22 is connected to the oil supply ring 23 fixedly installed on the horizontal plate 20 through a pipeline. The oil supply ring 23 is coaxially arranged with the feeding barrel 5. The oil supply ring 23 is connected to multiple groups of evenly distributed oil supply pipes 24. The oil supply pipes 24 are connected to multiple groups of hoses 25. The hoses 25 are respectively connected to the grooves on the two groups of heat dissipation plates 17 adjacent to the oil supply pipes 24, and the hoses 25 are connected to both sides of the grooves.

[0039] In actual application of this embodiment, after the heat sink 17 contacts the inner wall of the feeding barrel 5, the groove is a distribution space at this time, and the cooling oil in the oil tank 21 is extracted by the two-way oil pump 22, and then delivered to the groove through the oil supply ring 23, the oil supply pipe 24 and the hose 25 until the groove is filled with cooling oil and stops. The cooling oil contacts the inner wall of the feeding barrel 5, thereby achieving seamless contact with the inner wall of the feeding barrel 5, reducing the gap when the heat sink 17 contacts the inner wall of the feeding barrel 5, further improving the efficiency of heat transfer from the inner wall of the feeding barrel 5 to the heat sink 17, and further improving the heat dissipation effect;

[0040] When not in use, the bidirectional oil pump 22 reversely extracts the cooling oil in the groove and transports it to the oil tank 21. The cooling oil in the oil-absorbing sponge 19 flows downward under the action of gravity and is extracted. The extraction stops after the set extraction time. At this time, a small amount of cooling oil remains in the oil-absorbing sponge 19, and the heat sink 17 is separated from the feeding barrel 5.

[0041] like Figure 5 、 Figure 10 As shown, a spacing adjustment device for self-adhesive label printing provided by the present invention is provided. A second mounting rod 26 is fixedly installed in the feed barrel 5, and a scraper ring 27 is slidably installed on the second mounting rod 26. The scraper ring 27 is in sliding contact with the inner wall of the feed barrel 5, and a second servo module 28 is provided in the feed barrel 5 to drive the scraper ring 27 to move.

[0042] Specifically, a plurality of groups of arc-shaped closing plates 29 are fixedly mounted on the scraper ring 27 . The positions of the closing plates 29 correspond to the heat dissipation plates 17 and the closing plates 29 are used to close the grooves on the heat dissipation plates 17 .

[0043] In actual application of this embodiment, after the heat sink 17 is separated from the feeding barrel 5, the second servo module 28 drives the scraper ring 27 to move so that the closing plate 29 moves to the position where the heat sink 17 is located, and the closing plate 29 is used to close the groove on the heat sink 17, thereby preventing the cooling oil in the groove with the opening facing downward from the oil-absorbing sponge 19, avoiding leakage of the cooling oil, keeping the inside of the feeding barrel 5 clean, and thereby reducing the residual impurities on the inner wall of the feeding barrel 5. When used again later, the second servo module 28 drives the scraper ring 27 to move and clean the inner wall of the feeding barrel 5 through the scraper ring 27, and then makes the heat sink 17 contact with the inner wall of the feeding barrel 5, avoiding the presence of impurities at the contact position between the heat sink 17 and the inner wall of the feeding barrel 5, ensuring the sealing of the contact between the heat sink 17 and the inner wall of the feeding barrel 5, and further improving the heat dissipation capacity.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

[0045] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
