Description

Technical Field

[0001] The invention relates to the technical field of label printing technology, and in particular to a multifunctional intermittent PS plate label printing machine. Background Art

[0002] PS plate is the abbreviation of pre-coated photosensitive plate, which is a lithographic plate that is pre-coated with a photosensitive layer and can be exposed at any time. The base of the PS plate adopts an aluminum foil plate with good hydrophilicity, fine metal crystals and good chemical stability. In the printing process of the PS plate label, the PS plate label printing machine first applies a layer of photosensitive liquid on the base aluminum foil plate of the PS plate, and then performs subsequent cutting and printing operations. In the actual production process of the existing PS plate label printing machine, a spray head or a fixed-length coating roller is usually used to achieve the operation of coating the photosensitive liquid on the aluminum foil plate. Although this can ensure the quality of the PS plate, The aluminum foil plate used for PS plate labels can be fully coated with a sufficient amount of photosensitive liquid, but because the size of the PS plate label actually required is flexibly changed according to the usage scenario, the amount of photosensitive liquid sprayed or dipped by the existing device when spraying or smearing the photosensitive liquid is sometimes much more than the required amount. This coating method is relatively rigid, which will cause a large amount of photosensitive liquid to be wasted. Under such a printing method, the production cost of the PS plate label will increase, and the smaller the PS plate label, the more useless costs will be generated. In view of this, we propose a multifunctional intermittent PS plate label printing machine. Summary of the invention

[0031] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] A multifunctional intermittent PS plate label printing machine comprises a plurality of rotating shafts 1 arranged in a linear and equidistant structure, both ends of the rotating shafts 1 are rotatably connected with support plates 2, the bottom surfaces of the plurality of support plates 2 are on the same horizontal plane, a conveyor belt 3 is connected between the outsides of the plurality of rotating shafts 1, and a coating mechanism 4 is arranged above the middle of the conveyor belt 3;

[0033] The smearing mechanism 4 includes a hollow column 5, a plurality of conduits 6 uniformly penetrated through the outer wall of the hollow column 5 in a curved annular structure with equal spacing, such an arrangement structure enables the smearing structures on the plurality of rows of conduits 6 to be interlaced with each other and cover the surface of the aluminum foil plate for PS plate labels, so that the photosensitive liquid can be smeared more evenly and fully, the inside of the conduit 6 is elastically connected with a connecting tube 12, a sponge ball 7 fixedly provided on the outer wall of the hollow column 5 relative to the outer end of the conduit 6, a circular plate 8 rotatably connected to the left open end of the hollow column 5, a feed port 9 provided on the lower part of the circular plate 8 and on the support plate 2 on the left, a feed pipe 10 connected to the left end of the feed port 9, and a box 11 connected to the left end of the feed pipe 10, and the smearing mechanism 4 is used to smear the photosensitive liquid onto the surface of the aluminum foil plate on the conveyor belt 3.

[0034] Specifically, the inner end of the connecting tube 12 is a closed structure, and two through holes 13 are symmetrically provided at the inner ends of the outer walls on both sides of the connecting tube 12. Under normal circumstances, the connecting tube 12 will be located inside the conduit 6, so that the open end of the conduit 6 will be blocked by the open end of the connecting tube 12, and at the same time, the two through holes 13 on the connecting tube 12 will also be blocked by the conduit 6, thereby ensuring that the photosensitive liquid in the hollow column 5 will not leak out without external force. The outer wall of the conduit 6 is provided with a side groove 14, and the inner end of the side groove 14 is provided with a tension spring 15, and both ends of the tension spring 15 are They are respectively connected and fixed to the inner wall of the side groove 14 and the inner wall of the conduit 6. When the outer end of the connecting tube 12 is squeezed by the PS plate label on the conveyor belt 3, it will slide inward along the inside of the conduit 6 and stretch the tension spring 15. Because the length of the side groove 14 is greater than the tension spring 15, and when the outer wall of the side groove 14 contacts the outer end of the tension spring 15, the inner wall of the side groove 14 will not move to the inner side of the conduit 6, so the tension spring 15 will not contact the photosensitive liquid, thereby avoiding damage to the tension spring 15 caused by long-term immersion in the photosensitive liquid.

[0035] Furthermore, the sponge ball 7 is a hollow two-thirds spherical structure, and the outer end of the connecting tube 12 extends through the interior of the conduit 6 to the outside and is inside the sponge ball 7. When the end of the connecting tube 12 is squeezed and slides inward, the position of the through-hole 13 will also move to the inner side of the conduit 6, and then the photosensitive liquid in the hollow column 5 will flow into the through-holes 13 on both sides of the connecting tube 12 and flow into the sponge ball 7 along the connecting tube. Then the sponge ball 7 will absorb the photosensitive liquid and spread it evenly on the aluminum foil plate for PS plate labels during the subsequent rotation of the hollow column 5. The outer end of the sponge ball 7 is in sliding contact with the outer wall of the conveyor belt 3. When there is no product to be printed between the smearing mechanism 4 and the conveyor belt 3, the end of the connecting tube 12 on the inner side of the sponge ball 7 will not be squeezed. In this way, the connecting tube 12 will not provide a passage for the photosensitive liquid in the process without printing, and based on this principle, the smearing mechanism 4 of the device can freely adapt to the size of the product to be printed to prevent the waste of photosensitive liquid. The circular plate 8 and the hollow column 5 The left open end is a cylindrical structure with a cross-shaped cross section. In this way, the sealing effect can be achieved at this location while ensuring the rotational connection between the two, so as to prevent the photosensitive liquid in the hollow column 5 from leaking from the open end. The left wall of the circular plate 8 is fixedly connected to the right wall of the support plate 2 located in the middle of the left side. The position of the feed port 9 is located below the axial position of the circular plate 8. The top surface position of the feed pipe 10 is set flush with the inner top surface position of the box body 11. The position of the feed pipe 10 and the feed port 9 is lower than the circular plate 8 and the hollow column 5. The photosensitive liquid in the box body 11 is in the axial position, so the photosensitive liquid in the box body 11 will be added into the hollow column 5 through the feeding pipe 10 and the feeding port 9, and the liquid level will be kept consistent with the top surface height inside the box body 11. Therefore, the photosensitive liquid will only occupy part of the lower side of the hollow column 5, so as to avoid excessive photosensitive liquid remaining in the hollow column 5 when the device is out of use, and prevent it from being ineffective due to being placed for a long time in an unsuitable environment. In addition, the photosensitive liquid in the box body 11 can be pumped out and stored by an external pump body when the device is out of use.

[0036] Furthermore, the box body 11 is provided with a piston plate 16 that is slidably matched with the inside thereof, and the outer wall of the piston plate 16 is provided with a sealing ring 17. This structure is used to seal the space below the piston plate 16 to prevent the photosensitive liquid in the box body 11 from leaking to the bottom of the piston plate 16. A multi-section telescopic rod 18 is fixed between the bottom surface of the piston plate 16 and the bottom surface of the inner side of the box body 11. The multi-section telescopic rod 18 can guide the piston plate 16 to prevent its tilting and cause the sealing failure below. A threaded hole 19 is opened through the left side of the top surface of the box body 11. The threaded hole The inner thread of 19 is connected with a threaded plug 20, and the staff can add photosensitive liquid into the box body 11 from here, and the threaded hole 19 can be sealed through the threaded connection between the two, and the threaded plug 20 is designed as a T-shaped structure with a small top and a large bottom, so that the sealing of the threaded hole 19 after being blocked by the threaded plug 20 can be better guaranteed. An air bag 21 is provided on the left side of the box body 11, and a fixing seat 22 is fixed on the bottom surface of the air bag 21. An air pipe 23 is connected between the lower part of the air bag 21 and the box body 11. Under this design, the space between the inner bottom surface of the box 11 and the piston plate 16 The air can only move between the lower part of the box 11 and the air bag 21 through the air pipe 23. Therefore, when the staff adds photosensitive liquid into the box 11, the piston plate 16 will press the air into the air bag 21. Then, during the operation of the device, the photosensitive liquid in the hollow column 5 is used less and less, and the photosensitive liquid in the box 11 will be continuously replenished to the hollow column 5. However, the threaded hole 19 is sealed by the threaded plug 20 and cannot exchange air with the outside. In this way, the piston plate 16 can only move upward to adapt to the reduction of the photosensitive liquid. At the same time, the piston plate 16 6 also increases. In order to adapt to the change in space, the gas previously injected into the airbag 21 will return along the air pipe 23 to the position between the bottom surface of the box body 11 and the bottom surface of the piston plate 16. Under this series of actions, it can be ensured that the height of the photosensitive liquid level inside the box body 11 remains unchanged at all times, and then the photosensitive liquid level in the hollow column 5 will not change through the connection between the feed pipe 10 and the feed port 9, so that the device can quantitatively input a suitable amount of photosensitive liquid into the hollow column 5 without the need for electricity supply.

[0037] Furthermore, a motor 24 is fixedly provided on the support plate 2 located on the right side of the middle part, and the output end of the motor 24 is coaxially fixedly connected to the right end of the hollow column 5. The motor 24 can drive the hollow column 5 to rotate. A cavity 25 is opened inside the support plate 2 located on the right side of the middle part, and two turntables 26 are symmetrically sleeved with the output end of the motor 24 relative to the position inside the cavity 25. The outer wall of the turntable 26 located on the left side is a quarter-arc equidistant structure and is fixed with multiple tooth columns A27.

[0038] Furthermore, the outer wall of the turntable 26 located on the left side is annular and evenly spaced structure with multiple gear columns B28 fixed thereon. A gear 29 meshing with the gear column B28 is coaxially provided on the right side of the rotating shaft 1 located in the middle. Driven by the multiple gear columns B28, the gear 29 will also rotate at the same angular velocity. A cylinder 30 is coaxially fixedly connected to the left wall of the gear 29. A plurality of air holes 31 are evenly opened in the middle of the outer wall of the cylinder 30. A turbofan 32 is coaxially fixedly connected to the left end of the cylinder 30. The turbofan 32 will also rotate during the rotation of the cylinder 30, and then the turbofan 32 will generate suction through rotation. The left end of the cylinder 30 successively penetrates the rotating shaft 1 located in the middle and the support plate 2 located on the left side of the middle, extends to the left and is rotatably connected to both of them. The left open end of the cylinder 30 is flush with the left wall of the support plate 2 located on the left side of the middle.

[0039] It is worth mentioning that the outer wall of the rotating shaft 1 is annular and evenly spaced structure with multiple through grooves 33, a support seat 34 is fixedly arranged between the two support plates 2 in the middle, the support seat 34 is a cross-shaped structure, and a groove 35 is arranged on the top surface of the support seat 34, the groove 35 is an isosceles trapezoidal column structure, a filter plate 36 is fixedly arranged on the upper part of the groove 35, the top surface of the filter plate 36 and the top surface of the support seat 34 are in sliding contact with the inner wall of the conveyor belt 3, the top surface of the filter plate 36 can provide support for the conveyor belt 3, and will not hinder the smooth airflow on the conveyor belt 3 and the inside of the cylinder 30.

[0040] It is worth noting that the outer walls on both sides of the rotating shaft 1 are both annular and evenly spaced and fixed with a plurality of tooth columns C37, and the edge of the inner wall of the conveyor belt 3 is evenly spaced and fixed with a plurality of tooth columns D38 meshing with the tooth columns C37. The position of the tooth column D38 corresponds to the concave position on the support seat 34, so the support seat 34 will not hinder the movement of the tooth column D38. The right end of the tooth column C37 located on the right side of the middle extends into the cavity 25 and meshes with the tooth column A27. The support plate 2 located on the right side of the middle is provided with a position for the tooth column C37 to move, and the position is connected to the cavity 25. Moreover, because the tooth column A27 is arranged in a quarter arc equidistant structure, the tooth column A2 Each time the corresponding turntable 26 rotates one circle, the tooth column A27 can only move a limited number of corresponding tooth columns C37, and the tooth column C37 can only drive a limited number of tooth columns D38, which in turn brings about the effect that the conveyor belt 3 will move intermittently, so that the aluminum foil sheet for PS sticky notes transported on the conveyor belt 3 will only move a small distance each time, so that it can fully receive the photosensitive liquid coating operation of the coating mechanism 4. A plurality of through holes 39 are evenly opened on the conveyor belt 3. Under the suction force generated by the rotation of the turbo fan 32, the external air will be sucked in from the through holes 39 on the conveyor belt 3, and then enter the cylinder 3 through the filter plate 36, the through groove 33 and the air hole 31. 0, and the groove 35 is set to an isosceles trapezoidal column structure with a larger upper part and a smaller lower part. Under such a structure, the suction force generated by the airflow driven by the turbofan 32 can be limited to the corresponding position of the coating mechanism 4, and then the airflow can generate a certain suction force on the aluminum foil plate used for the PS plate label, so that its position on the conveyor belt 3 is more stable, and the coating mechanism 4 is prevented from deviating when applying the photosensitive liquid to the top surface thereof. On the other hand, when the coating mechanism 4 performs the coating operation at the edge of the PS plate, it is inevitable that part of the photosensitive liquid will overflow, and under the suction force generated by the turbofan 32, this small amount of overflowed photosensitive liquid will be sucked into the cylinder 30, and the two support plates located at the front side 2, a top plate 40 is fixedly arranged between the upper ends, and an electric heating plate 41 is embedded in the bottom surface of the top plate 40. After the smearing mechanism 4 has finished smearing the photosensitive liquid, the electric heating plate 41 can produce a heating effect on the photosensitive liquid to make it adhere to the surface of the aluminum foil plate more quickly and produce an effect, making the function of the device more diversified. A limiting groove 42 is arranged on the left side of the support plate 2 located in the middle of the left side, and a collecting box 43 is inserted in the limiting groove 42. A small amount of photosensitive liquid sucked into the cylinder 30 can flow out from the left open end of the cylinder 30 and flow into the collecting box 43. The limiting groove 42 can not only help the staff to quickly confirm the placement position of the collecting box 43, but also prevent the edge of the collecting box 43 from affecting the inflow of the photosensitive liquid.

[0041] Working principle: the aluminum foil plate used for the PS plate label to be printed is placed on the conveyor belt 3, and then the aluminum foil plate will move forward intermittently under the drive of the motor 24, and then be coated with photosensitive liquid when passing through the coating mechanism 4. During the process, the amount of photosensitive liquid used can be strictly limited and a small amount of excess photosensitive liquid can be recovered. Finally, the aluminum foil plate with the photosensitive liquid evenly coated on the surface will pass under the top plate 40 and be accelerated to fit to the aluminum foil plate under the heat of the electric heating plate 41. The staff can connect the rear side of this device with the remaining modules of the PS plate label printing operation. When the photosensitive liquid coating operation of the PS plate label printing is completed, it will be moved to the subsequent module and undergo subsequent printing processing.

[0042] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
