Description

Technical Field

[0001] This utility model relates to the field of express delivery waybill production technology, and in particular to a fully automatic coating machine for express delivery waybill production. Background Technology

[0002] A courier waybill is a document used in the courier industry to record information such as the sender, recipient, product weight, and price during the delivery of goods. One side of the courier waybill has an adhesive layer, which is then peeled off from the back and affixed to the courier box.

[0003] A label paper adhesive label coating device disclosed in the prior art (CN222057842U) includes a worktable, an unwinding assembly on the top surface of the worktable, a mounting frame fixedly mounted on the top surface of the worktable, a driving assembly on the surface of the mounting frame, a rotating shaft rotatably mounted on the surface of the mounting frame, a coating roller fixedly mounted on the surface of the rotating shaft, and a storage box fixedly mounted on the top surface of the mounting frame. Adhesive is sprayed from a discharge nozzle through a discharge pipe. The discharge nozzles are arranged in multiple sets evenly to ensure that the adhesive is evenly sprayed onto the surface of the coating roller. The driving assembly drives the rotating shaft to rotate, causing the coating roller to rotate and uniformly coat the label paper.

[0004] The aforementioned device, through the setting of the coating component, allows the lifting plate to move, thereby adjusting the height of the scraper to remove excess glue from the label paper surface and control the thickness of the glue on the label paper surface, resulting in a more uniform glue coating. However, the excess glue scraped off by the scraper will accumulate on the left side of the scraper over time. When it accumulates to an excessive amount, it will overflow and fall from both sides of the label paper, causing waste and pollution. It may also extend to the bottom of the label paper due to the surface tension of the liquid, contaminating the side of the label paper that does not need to be coated. Utility Model Content

[0005] The purpose of this invention is to solve the shortcomings of existing technologies, such as glue scraped off by a scraper overflowing from both sides, spreading to the back of the label paper, and falling off, causing waste and pollution. Therefore, this invention proposes a fully automatic coating machine for producing express delivery waybills.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a fully automatic coating machine for producing express delivery waybills, including a frame and express delivery waybills. The two ends and the top of the frame are respectively equipped with a winding assembly and a gluing assembly, and a scraper is installed inside the frame.

[0008] The outer wall of the scraper is slidably mounted with a pair of collection boxes located on both sides of the express waybill via a positioning component. Inside each collection box, a belt is rotatably mounted via a conveying component. Bristles are fixedly mounted on the outer wall of the belt. Inside each collection box, an isolation plate located at the bottom of the express waybill and a secondary scraper located at the bottom of the bristles are fixedly mounted. The outer wall of the bristles is slidably connected to the bottom and chamfer of the isolation plate.

[0009] Furthermore, the winding assembly includes an unwinding roller and a winding roller rotatably mounted in the frame, with the unwinding roller and winding roller respectively mounted at both ends of the frame. A winding motor is fixedly mounted on the outer wall of the frame by fasteners, and the output shaft of the winding motor passes through the frame and is fixedly connected to the winding roller.

[0010] Furthermore, the coating assembly includes a storage bin fixedly installed on the top of the frame. The bottom of the storage bin is integrally formed with a discharge port. The lower end of the discharge port passes through the frame and is fixedly installed with a valve. A discharge pipe is fixedly installed inside the frame. The top and bottom of the discharge pipe are integrally formed with an inlet connected to the valve at the top and several outlets, respectively. The lower ends of the several outlets are fixedly installed with glue nozzles. The lower ends of the several glue nozzles are rotatably mounted with coating rollers through a drive assembly.

[0011] Furthermore, the drive assembly includes a motor fixedly mounted on the top of the frame by fasteners and a rotating shaft fixedly mounted inside the coating roller. The two ends of the rotating shaft pass through and are rotatably connected to the frame.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 As an embodiment of this utility model, a fully automatic coating machine for producing express delivery waybills is disclosed, including a frame 1 and an express delivery waybill 2. The two ends and the top of the frame 1 are respectively provided with a winding assembly 3 and an adhesive coating assembly 4, and a scraper 5 is installed inside the frame 1.

[0022] The rewinding assembly 3 unwinds and rewinds the express waybill 2, and pulls the express waybill to the right, so that the express waybill passes through the glue application assembly 4 and the scraper 5 in sequence. The glue application assembly 4 applies glue to the upper surface of the express waybill 2, and the scraper 5 scrapes the glue flat and blocks the excess glue on the left side of the scraper 5.

[0023] The outer wall of the scraper 5 is slidably mounted with a pair of collection boxes 7 located on both sides of the express waybill 2 via the positioning component 6. Each collection box 7 has a belt 9 rotatably mounted inside via the conveying component 8. The outer wall of the belt 9 is fixedly mounted with bristles 10. Each collection box 7 has a partition plate 11 located at the bottom of the express waybill 2 and a secondary scraper 12 located at the bottom of the bristles 12. The outer wall of the bristles 12 is slidably connected to the bottom and chamfer of the partition plate 8. Preferably, the bottom of the collection box 7 is integrally formed with a glue outlet for discharging glue. The lower end of the glue outlet is threadedly connected with a sealing cap. The outer end of the chamfer at the bottom of the partition plate 8 is aligned with the outer end of the express waybill 2.

[0024] When excessive glue accumulates on the left side of the scraper 5 and overflows from both sides of the waybill, the overflowing glue falls onto the upper surface of the bristles 10 on both sides of the waybill 2 and is absorbed by the brushes 10, thus preventing the glue from falling and spreading to the back of the waybill. The conveyor assembly drives the belt 9 and the bristles 10 on it to rotate, so that the bristles 10 rotate with the belt 9 and the top bristles 10 move away from the waybill 2, avoiding contact between the absorbed glue and the bottom of the waybill. When the bottom of the rotating blade is reached, the secondary scraper 12 squeezes the bristles 10 to scrape off the glue contained in the bristles and makes it fall down the outer side of the secondary scraper to the bottom of the collection box 7. The partition plate 8 presses down on the comb 10 and isolates the bristles 10 from the waybill 2, preventing the glue remaining in the bristles 10 from contaminating the bottom of the waybill. The chamfers located at the bottom and outer ends of the partition plate 8 make the bristles adhere to the chamfers when they leave the bottom of the partition plate 8 and gradually recover, and they are completely recovered at the outer end of the chamfer.

[0025] For example, the winding assembly 3 includes an unwinding roller 31 and a winding roller 32 rotatably mounted in the frame 1, and the unwinding roller 31 and the winding roller 32 are respectively mounted at both ends of the frame 1. A winding motor 33 is fixedly mounted on the outer wall of the frame 1 by fasteners, and the output shaft of the winding motor 33 passes through the frame 1 and is fixedly connected to the winding roller 32.

[0026] After fixing the right end of the express delivery waybill to the take-up roller 32, the take-up motor 33 drives the take-up roller 32 to rotate and take up the express delivery waybill 2 while pulling it to the right.

[0027] Furthermore, the adhesive application assembly 4 includes a storage tank 41 fixedly installed on the top of the frame 1. The bottom of the storage tank 41 is integrally formed with a discharge port 42. The lower end of the discharge port 42 passes through the frame 1 and is fixedly installed with a valve 43. The inside of the frame 1 is fixedly installed with a discharge pipe 44. The top and bottom of the discharge pipe 44 are integrally formed with an inlet 45 that connects to the valve 43 at the top and several outlets 46, respectively. The lower ends of the several outlets 46 are fixedly installed with adhesive nozzles 47. The lower ends of the several adhesive nozzles 47 are rotatably installed with coating rollers 49 through a drive assembly 48.

[0028] Open valve 43 so that the glue inside storage tank 41 enters valve 43 through outlet 42 and enters outlet pipe 14 through valve 43 and inlet 45, and then enters several glue nozzles 47 through several outlets 46 and is sprayed out and falls onto coating roller 49.

[0029] Furthermore, the drive assembly 48 includes a motor 481 fixedly mounted on the top of the frame 1 by fasteners and a rotating shaft 482 fixedly mounted inside the coating roller 49. The two ends of the rotating shaft 482 pass through and are rotatably connected to the frame 1. One end of the rotating shaft 482 and the output shaft of the motor 481 are both fixedly mounted with pulleys 483, and the outer walls of the two pulleys 483 are fitted with transmission belts 484.

[0030] The coating roller 49 is rotated by the motor 481, which evenly distributes the glue onto the surface of the coating roller 49 and coats it onto the express waybill 2 when it rotates to the bottom.

[0031] In some embodiments, the positioning component 6 includes an insertion hole 61 formed on the outer wall of the collection box 7, a scraper 5 is inserted into the insertion hole 61, and a threaded hole 62 with its lower end communicating with the insertion hole 61 is formed on the top of the collection box 7. A positioning screw 63 is threadedly connected to the inside of the threaded hole 62, and the lower end of the positioning screw 63 abuts against the scraper 5.

[0032] The collection box 7 can be slid back and forth by loosening the positioning screw 62 to adjust its position so that the outer end of the chamfer of the partition plate 8 inside the collection box 7 is aligned with the outer end of the express waybill 2, thus accommodating express waybills 2 of different widths. After adjustment, tighten the positioning screw 62 so that the lower end abuts against the scraper 5, thereby positioning the collection box 7 by the friction between the positioning screw 62 and the scraper 5 to prevent it from sliding back and forth.

[0033] It should be noted that the conveying assembly 8 includes a pair of rollers 81 rotatably mounted inside the collection box 7, and a belt 9 is sleeved on the outer wall of the pair of rollers 81. A motor 82 is fixedly mounted on the outer wall of the collection box 7 by fasteners. The output shaft of the motor 82 is fixedly inserted through the collection box 7 and fixedly connected to the rollers 81. The motor 82 drives the rollers 81 to rotate, thereby driving the belt 9 to rotate.

[0034] Working method: The rewinding assembly 3 unwinds and rewinds the express waybill 2, and pulls the express waybill to the right, so that the express waybill passes through the glue application assembly 4 and the scraper 5 in sequence. The glue application assembly 4 applies glue to the upper surface of the express waybill 2, and the scraper 5 scrapes the glue flat and blocks the excess glue on the left side of the scraper 5. When too much glue accumulates on the left side of the scraper 5 and overflows from the front and back sides of the express waybill, the glue overflows and falls onto the upper surface of the brush bristles 10 on both sides of the express waybill 2 and is absorbed by the brush bristles 10.

[0035] The motor 82 drives the roller 81 to rotate, which in turn drives the belt 9 and the bristles 10 on it to rotate. As the belt 9 rotates, the bristles 10 at the top move away from the waybill 2. When the bottom of the rotating blade of the bristles 10 is reached, the secondary scraper 12 squeezes the bristles 10 to remove the glue contained in the bristles 10 and causes them to fall down along the outer side of the secondary scraper 12 to the bottom of the collection box 7. The partition plate 8 presses down on the bristles 10 and separates the bristles 10 from the waybill 2, preventing the glue residue in the bristles 10 from contaminating the bottom of the waybill. The chamfers located at the bottom and outer ends of the partition plate 8 cause the bristles to adhere to the chamfers when they leave the bottom of the partition plate 8 and gradually recover. They are fully recovered at the outer end of the chamfer and can then absorb the overflowing glue again.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
