Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of color box printing and coating, and particularly relates to a coating device for protective oil on the printing surface of a packaging color box. Background Technique
[0002] In the printing production process of color boxes, in order to achieve the use effects of color boxes in different scenarios, different processes are used for the production of color boxes. To improve the waterproof ability of color boxes, generally two processes can achieve this effect. One is the oiling process, and the other is the laminating process. The situation corresponding to the oiling process is that the protection requirement is not high. It can be waterproof but not resistant to repeated cleaning and will fall off after several cleanings. However, its process is simple, the production efficiency is high, and the cost is low. The laminating process can withstand repeated cleaning, but its production requirements are high, the difficulty is great, and the cost is also high. The two different waterproof processes can be used for color boxes with different requirements. However, today's oiling process is also carried out in the form of full-width oiling, which still leads to increased costs for color boxes with low protection requirements. Especially when only specific fonts or shapes need to be oiled for protection to ensure that the printed information can still be maintained after several wipes, if it is produced in the form of full-width oiling, it will cause a sharp increase in production costs, which is not conducive to the cost reduction and efficiency improvement of enterprises. Content of the Utility Model
[0003] To solve the above technical problems, the utility model provides a coating device for protective oil on the printing surface of a packaging color box. By concentrating the printed information on the printing template, dropping the oiling material on the printing template, and scraping the coating plate back and forth on the printing template, the oiling material is pressed on the color plate on the conveyor belt, so that the specific positions on the color plate are coated with the oiling material of a specific shape, avoiding waste of materials caused by large-area oiling and ensuring that the oiled content can meet the use requirements.
[0004] To achieve the above purpose, the technical scheme adopted by the utility model is as follows:
[0005] A coating device for protective oil on the printing surface of a packaging color box includes a frame, a conveyor belt, a template assembly, and a coating assembly. The conveyor belt is rotatably connected to the frame. The template assembly is arranged on the frame. The template assembly is horizontally arranged above the conveyor belt and does not contact the conveyor belt. The coating assembly includes a coating plate and a feeding port. The coating plate and the feeding port are arranged above the template assembly and are respectively in abutting connection with the template assembly. The template assembly includes a printing template and a fixing seat. The printing template is connected to the frame through the fixing seat.
[0006] The coating assembly further includes a lateral movement assembly, a vertical movement assembly, and a moving seat. The lateral movement assembly is disposed on the frame. The moving seat is movably connected to the lateral movement assembly. The vertical movement assembly is movably connected to the moving seat. The coating plate and the feeding port are respectively connected to the vertical movement assembly. The lateral movement assembly includes a lateral movement cylinder, a lateral movement seat, and a lateral movement rail. The lateral movement rail is connected to the frame through the lateral movement seat. The moving seat is provided with a lateral movement hole which is matched with the lateral movement rail. The lateral movement cylinder is connected to the frame, and the output end of the lateral movement cylinder is connected to the moving seat. The vertical movement assembly includes a first cylinder and a second cylinder. The first cylinder and the second cylinder are respectively disposed on the moving seat. The output end of the first cylinder is connected to the coating plate, and the output end of the second cylinder is connected to the feeding port. The coating plate and the feeding port are parallel to each other.
[0007] For the packaging color box printing surface protective oil coating device adopting this structure, the frame provides support. The conveyor belt on the frame is used to convey the color boxes to be printed. The conveyor belt is the most common transmission structure, so its transmission method and structural composition will not be elaborated here. The template assembly is horizontally placed above the conveyor belt and is not parallel to the conveyor belt. The printing template of the template assembly is hollowed out and engraved with text or pattern information, aiming to have a notch during the process of overcoating with oil to coat the overcoating material on the color box. In order to keep a fixed distance between the printing template and the conveyor belt, a fixing seat is added and the printing template is connected to the fixing seat.
[0008] Since the overcoating material needs to be scraped and fed after being placed on the printing template so that the overcoating material can be pressed on the color plate through the hollowed text or pattern information, a coating plate is provided for scraping the overcoating material, and the feeding port is provided for adding the overcoating material. The coating plate and the feeding port are arranged in parallel. During the process of feeding, the coating plate presses down to scrape the material. Therefore, the coating plate and the feeding port need to achieve two-directional movement, one is the longitudinal movement towards the printing template, and the other is the lateral movement for scraping the printing template. Therefore, the lateral movement and the longitudinal movement are realized through the lateral movement assembly and the vertical movement assembly. The lateral movement cylinder included in the lateral movement assembly is disposed on the frame. The lateral movement rail is connected to the frame through the lateral movement seat. The output end of the lateral movement cylinder is connected to the lateral movement seat, and the lateral movement seat is movably connected to the lateral movement rail through the lateral movement hole. Therefore, the lateral movement seat can move laterally under the drive of the lateral movement cylinder, and the coating plate and the feeding port are respectively movably connected to the lateral movement seat through the first cylinder and the second cylinder.
[0009] In order to achieve batch production of reciprocally coating the oiling material on the color box, it is necessary to realize repeated scraping of the oiling material for oiling coating through the linkage of the horizontal translation component and the vertical translation component. From the front view, when the color box is driven by the conveyor belt to under the printing template, the horizontal translation seat moves to the upper left end of the hollow part, first presses down the feeding port, makes the opening of the feeding port abut against the upper end surface of the printing template, and extrudes the oiling material onto the printing template. After completing the extrusion of the material, the feeding port is lifted, and at the same time, the coating plate is pressed down. The coating plate makes the lower end surface of the printing template abut against the color box. The printing template is made of a deformable elastic material and can be slightly deformed during the process of being pressed down by the coating plate to meet the requirement of abutting against the color box. After the coating plate finishes pressing and feeding the printing template, it moves to the right under the drive of the horizontal translation cylinder. The coating plate then scrapes on the printing template, scraping the oiling material to the right. During this process, after passing through the hollow part, the oiling material is coated on the color box, and the excess oiling material is scraped to the right. The coating plate is lifted. At this time, the printing template returns to its original state. The color box on the conveyor belt can continue to be conveyed into the next process, and the unprinted color box is conveyed under the printing template to wait for coating. The feeding port is pressed down again onto the upper end surface of the printing template, and the horizontal translation cylinder is restarted to push the horizontal translation seat to the left. The lower opening of the feeding port then pushes the oiling material from right to left until the oiling material stops at the left end for the next reciprocating production.
[0010] Further, a pushing end extending downward is provided on the side wall of the lower opening of the feeding port parallel to the side wall of the coating plate.
[0011] Compared with the prior art, the advantages of the present utility model are as follows: By adding the oiling material to the printing template, the printing template abuts against the color box under the pressing of the coating plate and through horizontal scraping, the oiling material is coated on the color box through the hollow part. The remaining oiling material returns to the left side under the scraping of the discharge port and waits for the next oiling material coating. Since the printing template is made of an elastic material, it can be abutted against the color box through deformation, so that the oiling material can be coated at specific positions, and specific information can be coated at specific positions, avoiding waste caused by large-area oiling.

[0020] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0021] The following will describe the detailed implementation manners of the present utility model with reference to the accompanying drawings:
[0022] As Figure 1-6 shown, a coating device for the printed surface protective oil of a packaging color box includes a frame 1, a conveyor belt 2, a template assembly 3 and a coating assembly 4. The conveyor belt 2 is rotatably connected to the frame 1. The template assembly 3 is arranged on the frame 1. The template assembly 3 is horizontally arranged above the conveyor belt 2 and does not contact the conveyor belt 2. The coating assembly 4 includes a coating plate 41 and a feed inlet 42. The coating plate 41 and the feed inlet 42 are arranged above the template assembly 3 and are respectively in abutting connection with the template assembly 3. The template assembly 3 includes a printing template 31 and a fixed seat 32. The printing template 31 is connected to the frame 1 through the fixed seat 32.
[0023] The coating assembly 4 further includes a transverse movement assembly 43, a vertical movement assembly 44, and a moving seat 45. The transverse movement assembly 43 is arranged on the frame 1. The moving seat 45 is movably connected to the transverse movement assembly 43. The vertical movement assembly 44 is movably connected to the moving seat 45. The coating plate 41 and the feed inlet 42 are respectively connected to the vertical movement assembly 44. The transverse movement assembly 43 includes a transverse movement cylinder 431, a transverse movement seat 432, and a transverse movement rail 433. The transverse movement rail 433 is connected to the frame 1 through the transverse movement seat 432. The moving seat 45 is provided with a transverse movement hole 451 which is matched with the transverse movement rail 433. The transverse movement cylinder 431 is connected to the frame 1, and the output end of the transverse movement cylinder 431 is connected to the moving seat 45. The vertical movement assembly 44 includes a first cylinder 441 and a second cylinder 442. The first cylinder 441 and the second cylinder 442 are respectively arranged on the moving seat 45. The output end of the first cylinder 441 is connected to the coating plate 41, and the output end of the second cylinder 442 is connected to the feed inlet 42. The coating plate 41 and the feed inlet 42 are parallel to each other.
[0024] Further, a downwardly extending pushing end 421 is provided on the side wall of the lower end opening of the feed inlet 42 parallel to the coating plate 41.
[0025] The working mode of the present utility model is described as follows:
[0026] For the packaging color box printing surface protective oil coating device adopting this structure, the frame 1 serves to provide support. The conveyor belt 2 on the frame 1 is used to convey the color boxes to be printed. The conveyor belt 2 is the most common transmission structure, so its transmission mode and structural composition will not be elaborated here. The template assembly 3 is horizontally placed above the conveyor belt 2 and is not parallel to the conveyor belt 2. The printing template 31 of the template assembly 3 is hollowed out and engraved with text or pattern information, aiming to have a notch during the process of coating with oil so that the oiling material can be coated on the color box. In order to keep a fixed distance between the printing template 31 and the conveyor belt 2, a fixing seat 32 is added, and the printing template 31 is connected to the fixing seat 32.
[0027] After the oiling material is placed on the printing template 31, the printing template 31 needs to be scraped and fed so that the oiling material can be pressed on the color plate through the hollowed text or pattern information. Therefore, a coating plate 41 is provided for scraping the oiling material, and a feeding port 42 is provided for adding the oiling material. The coating plate 41 and the feeding port 42 are arranged in parallel. During the feeding process, the coating plate 41 presses down to scrape the material. Therefore, the coating plate 41 and the feeding port 42 need to achieve two-way movement. One is the longitudinal movement towards the printing template 31, and the other is the transverse movement for scraping the printing template 31. Therefore, the transverse movement and the longitudinal movement are realized through a transverse movement assembly 43 and a vertical movement assembly 44. The transverse movement cylinder 431 included in the transverse movement assembly 43 is arranged on the frame 1, and the transverse movement rail 433 is connected to the frame 1 through a transverse movement seat 432. The output end of the transverse movement cylinder 431 is connected to the transverse movement seat 432, and the transverse movement seat 432 is movably connected to the transverse movement rail 433 through a transverse movement hole 451. Therefore, under the drive of the transverse movement cylinder 431, the transverse movement seat 432 can perform transverse movement, and the coating plate 41 and the feeding port 42 are respectively movably connected to the transverse movement seat 432 through a first cylinder 441 and a second cylinder 442.
[0028] In order to achieve batch production of reciprocally coating the oiling material on the color box, it is necessary to realize repeated scraping of the oiling material for oiling coating through the linkage of the horizontal movement component 43 and the vertical movement component 44. From the front view, when the color box is driven by the conveyor belt 2 to under the printing template 31, the horizontal movement seat 432 moves to the upper left end of the hollow part, first presses down the feeding port 42, makes the opening of the feeding port 42 abut against the upper end face of the printing template 31, and extrudes the oiling material onto the printing template 31. After completing the extrusion of the material, the feeding port 42 is lifted, and at the same time, the coating plate 41 is pressed down. The coating plate 41 makes the lower end face of the printing template 31 abut against the color box. The printing template 31 is made of a variable elastic material and can be slightly deformed during the process of being pressed down by the coating plate 41 to meet the requirement of abutting against the color box. After the coating plate 41 finishes pressing and sending the printing template 31, it moves to the right under the drive of the horizontal movement cylinder 431. The coating plate 41 then scrapes on the printing template 31, scraping the oiling material to the right. During this process, after passing through the hollow part, the oiling material is coated on the color box, and the excess oiling material is hung to the right. The coating plate 41 is lifted. At this time, the printing template 31 returns to its original state. The color box on the conveyor belt 2 can continue to be conveyed into the next process, and the unprinted color box is conveyed under the printing template 31 to wait for coating. The feeding port 42 is pressed down again onto the upper end face of the printing template 31, and the horizontal movement cylinder 431 is restarted to push the horizontal movement seat 432 to the left. The lower end opening of the feeding port 42 then pushes the oiling material from right to left until the oiling material stops at the left end for the next reciprocating production. In order to facilitate the discharging of the feeding port 42, the lower end face of the feeding port 42 is set as a downward extending pushing end 421. When discharging, the oiling material can be extruded from the right end. When the feeding port 42 is at the right end and the remaining oiling material needs to be pushed to the left, the lower end opening of the feeding port 42 parallel to the pushing end 421 provided on the side wall of the coating plate 41 can just push the remaining material to the left, and the extrusion of the raw material at the right end will not be affected after the pushing. Therefore, with the setting of this pushing end 421, it is possible to better scrape and extrude the raw material.
[0029] The beneficial effects of the present utility model are as follows: By adding the oiling material to the printing template 31, the printing template 31 abuts against the color box under the pressing of the coating plate 41 and is coated on the color box through the hollow part by horizontal scraping. The remaining oiling material returns to the left side again under the scraping of the discharging port and waits for the next oiling material coating. Since the printing template 31 is an elastic material, it can abut against the color box through deformation, so that the oiling material can be coated at specific positions, and specific information can be coated at specific positions, avoiding waste caused by large-area oiling.
[0030] 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 foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
