Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, specifically to an unwinding device for a printing production line. Background Technology

[0002] In the printing production process, roll materials (such as paper, plastic film, aluminum foil, etc.) are widely used as the main printing substrate. Unwinding equipment is a key starting point of the printing production line. Its main function is to continuously release and transport the rolled raw materials to subsequent printing, coating, laminating and other processes.

[0003] Traditional unwinding equipment mainly consists of a frame, an unwinding roller (air shaft), and a drive assembly. The unwinding roller is used to install and fix the roll material, and the drive assembly drives the air shaft to rotate, thereby releasing the roll material and conveying it to subsequent processes. The conveying path can be coordinated with tension control devices and correction devices on the printing production line to achieve smooth conveying.

[0004] However, in actual use, when the unwinding roller rotates, it easily disturbs the flow of the surrounding air and forms local airflow. These airflows can easily carry dust, fibers and other tiny particulate impurities suspended on the ground or in the air to the surface of the roll material. In particular, when the roll material has a certain electrostatic attraction, dust and impurities are more easily attracted to it, causing the roll material to be contaminated by particulate impurities, which in turn affects the quality of subsequent printed materials. Utility Model Content

[0005] This utility model provides a printing production line unwinding device that, by starting a vacuum cleaner, can clean and collect particulate impurities adhering to the surface of the roll material due to airflow disturbance. By setting up an antistatic brush, it can effectively eliminate static electricity on the roll material, cleaning the surface of the roll material more efficiently. This solves the problem mentioned in the background art of local airflow carrying particulate impurities to contaminate the roll material, thereby affecting the quality of printed products.

[0006] This utility model provides the following technical solution: A printing production line unwinding device includes a frame and an unwinding roller rotatably mounted on the frame. It further includes: at least two dust collection hoods fixedly connected to the frame, wherein the dust collection ports of both dust collection hoods face the surface of the roll material; a dust removal section is provided on the frame to generate a continuous negative pressure suction force within the dust collection hoods; and an antistatic brush disposed on the dust collection hoods, the antistatic brush being grounded via a wire, wherein the antistatic brush is located at the dust collection port of the dust collection hood, and the bristles of the antistatic brush are in contact with the surface of the roll material; and an adjusting component is provided on the dust collection hood for driving the antistatic brush to rise and fall.

[0007] As a preferred technical solution of this utility model, the dust removal unit includes a vacuum cleaner fixedly installed on the frame. The air inlet of the vacuum cleaner is connected to the dust hood through a suction pipe. The exhaust end of the vacuum cleaner is fixedly connected to a dust discharge pipe, and a dust removal bag is provided at the end of the dust discharge pipe away from the vacuum cleaner.

[0008] As a preferred technical solution of this utility model, the dust collector bag is fitted with an elastic sleeve at the bag opening, and the dust collector bag is fixedly fitted onto the dust discharge pipe by the elastic force of the elastic sleeve.

[0009] As a preferred embodiment of this utility model, the adjusting component includes a support plate fixedly connected to both sides of the dust collection hood, a stud threadedly connected to the support plate, and an anti-static brush connected to the end of the support plate via an mounting component.

[0010] As a preferred embodiment of this utility model, the mounting component includes a mounting frame, which is rotatably connected to the end of a stud. A screw is threaded onto the mounting frame, and an anti-slip pad is rotatably connected to the end of the screw, with the anti-slip pad abutting against the surface of the antistatic brush.

[0011] As a preferred embodiment of this utility model, a servo motor is fixedly installed inside the frame, the unwinding roller is rotatably connected to the frame, and the output end of the servo motor and the shaft end of the unwinding roller are both fixedly connected with meshing gears.

[0012] Compared with the prior art, this utility model provides a printing production line unwinding device, which has the following beneficial effects: 1. In the unwinding equipment of this printing production line, by starting the dust collector, particulate impurities attached to the surface of the roll material due to airflow disturbance can be cleaned and collected, which can greatly reduce problems such as spots and color deviation in subsequent printed products, thereby helping to improve the quality of subsequent printed products.

[0013] 2. In the unwinding equipment of this printing production line, the antistatic brush can effectively conduct the static charge on the roll material and quickly transfer it to the ground, thereby eliminating static electricity and reducing the adhesion of dust, fibers and other small particulate impurities to the roll material. At the same time, the negative pressure of the dust suction hood can clean the surface of the roll material more efficiently, further improving the quality of printed products.

[0014] 3. In the unwinding equipment of this printing production line, the antistatic brush can be driven to rise and fall by rotating the stud, so as to adjust the distance between the antistatic brush and the surface of the roll material, adapt to roll materials of different thicknesses, and ensure that the brush bristles can effectively contact the surface of the roll material, thereby optimizing the cleaning effect and preventing damage to the roll material.

[0015] 4. In the unwinding equipment of this printing production line, by rotating the screw, the anti-slip pad can be driven to press against or move away from the anti-static brush, which facilitates the flexible disassembly and assembly of the anti-static brush, making it easy to replace it, improving production continuity and efficiency.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example: Reference Figures 1-5 A printing production line unwinding device includes a frame 1 and an unwinding roller 2 rotatably mounted on the frame 1. Here, the unwinding roller 2 is an air-expanding shaft, which can be used to install and fix the roll material by inflation. It also includes: at least two dust collection hoods 3 fixedly connected to the frame 1, with the dust collection ports of the two dust collection hoods 3 facing the surface of the roll material. The frame 1 is provided with a dust removal part, which is used to generate a continuous negative pressure suction force inside the dust collection hoods 3. An antistatic brush 4 is provided on the dust collection hood 3. The antistatic brush 4 can be of the Randmaker TR-01 model. The antistatic brush 4 is grounded through a wire and is used to conduct the static charge on the roll material to the bottom surface. The antistatic brush 4 is located at the dust collection port of the dust collection hood 3, and the bristles of the antistatic brush 4 are in contact with the surface of the roll material. The dust collection hood 3 is provided with an adjusting component for driving the antistatic brush 4 to rise and fall.

[0022] Specifically, the dust removal unit and the dust collection hood 3 work together to clean and collect particulate impurities adhering to the surface of the roll material due to airflow disturbance. This greatly reduces problems such as spots and color deviations in subsequent printed materials, thereby improving the quality of subsequent printed materials. Furthermore, the antistatic brush 4 effectively conducts the static charge on the roll material, quickly transferring it to the ground to eliminate static electricity and reduce the adhesion of dust, fibers, and other tiny particulate impurities to the roll material. At the same time, the negative pressure of the dust collection hood 3 can more efficiently clean the surface of the roll material, further improving the quality of printed materials. The adjustable parts can drive the antistatic brush 4 to rise and fall, allowing for adjustment of the distance between the antistatic brush 4 and the roll material surface to adapt to roll materials of different thicknesses. This ensures that the bristles can effectively contact the roll material surface, optimizing the cleaning effect and preventing damage to the roll material. It also allows for flexible disassembly and assembly of the antistatic brush 4, making it easy to replace.

[0023] Of course, in other embodiments, the dust removal unit includes a vacuum cleaner 31 fixedly mounted on the frame 1. The model of the vacuum cleaner 31 can be Nilfisk-ATTIX965 or Delfin-DP3030. The air inlet of the vacuum cleaner 31 is connected to the dust hood 3 through the suction pipe 32. The exhaust end of the vacuum cleaner 31 is fixedly connected to the dust discharge pipe 33. A dust removal bag 34 is provided at the end of the dust discharge pipe 33 away from the vacuum cleaner 31. An elastic sleeve 35 is provided at the opening of the dust removal bag 34. The dust removal bag 34 is fixedly fitted onto the dust discharge pipe 33 by the elastic sleeve 35.

[0024] Specifically, during use, by starting the vacuum cleaner 31, negative pressure is generated inside the vacuum hood 3, which can suck the particulate impurities attached to the surface of the roll material into the vacuum hood 3, and discharge them into the dust collection bag 34 through the vacuum pipe 32 and the dust discharge pipe 33. This can clean and collect the particulate impurities attached to the surface of the roll material due to airflow disturbance, which can greatly reduce the occurrence of problems such as spots and color deviations in subsequent printed products, thereby helping to improve the quality of subsequent printed products. In addition, the elastic sleeve 35 can flexibly disassemble and assemble the dust collection bag 34, making it convenient to dump the collected particulate impurities.

[0025] The adjusting component includes support plates 5 fixedly connected to both sides of the dust cover 3. A stud 51 is threaded onto the support plate 5. An antistatic brush 4 is connected to the end of the support plate 5 through a mounting component. The mounting component includes a mounting frame 6, which is rotatably connected to the end of the stud 51. A screw 61 is threaded onto the mounting frame 6, and an anti-slip pad 62 is rotatably connected to the end of the screw 61. The anti-slip pad 62 abuts against the surface of the antistatic brush 4. The anti-slip pad 62 is made of rubber.

[0026] Specifically, during use, rotating the stud 51 drives the antistatic brush 4 to rise and fall, thereby adjusting the distance between the antistatic brush 4 and the surface of the roll material to adapt to roll materials of different thicknesses. This ensures that the bristles can effectively contact the surface of the roll material, achieving optimized cleaning results and preventing damage to the roll material. In addition, rotating the screw 61 drives the anti-slip pad 62 to press against or move away from the antistatic brush 4, facilitating flexible disassembly and assembly of the antistatic brush 4 for easy replacement, improving production continuity and efficiency. Furthermore, different types or specifications of brushes can be replaced according to the roll material and cleaning requirements to adapt to different production needs.

[0027] A servo motor 21 is fixedly installed inside the frame 1. The servo motor 21 can be a Panasonic A6 series or a Schneider Electric LXM32. The unwinding roller 2 is rotatably connected to the frame 1. The output end of the servo motor 21 and the shaft end of the unwinding roller 2 are both fixedly connected with meshing gears 22.

[0028] Specifically, in use, by starting the servo motor 21, the output end of the servo motor 21 drives the gear 22 to rotate, which in turn drives the unwinding roller 2 to rotate, thereby releasing and conveying the installed and fixed roll material.

[0029] In this utility model, when in use, the roll material is first put on the unwinding roller 2 and inflated to fix it. By starting the servo motor 21 and driving the unwinding roller 2 to rotate, the installed and fixed roll material can be released and transported. Furthermore, during use, by starting the vacuum cleaner 31, negative pressure is generated inside the vacuum hood 3, which can suck the particulate impurities attached to the surface of the roll into the vacuum hood 3, and discharge them into the dust collection bag 34 through the vacuum pipe 32 and the dust discharge pipe 33. This can clean and collect the particulate impurities attached to the surface of the roll due to airflow disturbance, which can greatly reduce the occurrence of problems such as spots and color deviation in subsequent printed products, thereby helping to improve the quality of subsequent printed products. In addition, during the cleaning process, the anti-static brush 4 can effectively conduct the static charge on the roll material, allowing it to be quickly transferred to the ground, thereby eliminating static electricity and reducing the adhesion of dust, fibers, and other small particulate impurities to the roll material. At the same time, the negative pressure of the dust hood 3 can clean the surface of the roll material more efficiently, further improving the quality of printed materials.
