Description

Technical Field

[0001] This application belongs to the technical field of laminating machines, and particularly relates to a laminating machine with a cardboard pre-cleaning mechanism. Background Technology

[0002] Laminating machines can be divided into two main categories: instant laminating machines and pre-coating laminating machines. They are specialized equipment used for laminating paper, boards, and other materials. The laminating process involves pressing the materials together using rubber rollers and heated rollers to create a paper-plastic composite product. Existing laminating machines typically feed the cardboard directly between the pressure rollers and heating rollers for lamination, lacking a pre-cleaning mechanism for the cardboard surface. Because dust, paper scraps, and other impurities easily adhere to the cardboard surface during storage and transport, these impurities become trapped between the cardboard and the laminating material during the lamination process. This leads to quality defects such as bubbles, wrinkles, and partial peeling in the laminated product, affecting its appearance and performance. Utility Model Content

[0003] The purpose of this application is to address the aforementioned technical problems by providing a laminating machine with a cardboard pre-cleaning mechanism. This mechanism can clean dust, paper scraps, and other impurities adhering to the surface of the cardboard during the conveying process, preventing these impurities from being trapped between the cardboard and the laminating material during the laminating process. This would prevent quality defects such as bubbles, wrinkles, and partial peeling from occurring in the laminated product, thus affecting the product's appearance and performance.

[0004] This application provides a laminating machine with a paperboard pre-cleaning mechanism, including a support plate, a material roller, a pressure roller, a heating roller, and further comprising: Support frame, which is mounted on a support plate; A cleaning component, used for pre-cleaning cardboard that needs to be laminated; The cleaning assembly includes a support cylinder, a dust collection box, a fan box, a dust collection pipe, and a negative pressure fan. The support cylinder is mounted on a support frame. Several dust collection boxes are mounted on the support cylinder. The fan box is a ring-shaped cylinder and is mounted on the support cylinder. One end of the dust collection pipe has several branch pipes, all of which are located inside the dust collection box. The other end passes through the support cylinder and into the fan box. The fan box has an opening on its side, and the negative pressure fan is mounted at the opening on the side of the fan box.

[0005] The basic structure of this laminating machine with a cardboard pre-cleaning mechanism includes a support plate, material rollers, pressure rollers, and heating rollers. A support frame and a cleaning assembly for pre-cleaning the cardboard to be laminated are added to this structure. The support frame is directly mounted on the support plate, providing stable support for the cleaning assembly. The core component of the cleaning assembly, the support cylinder, is located on the support frame, and several dust collection boxes are arranged on the support cylinder for adsorbing impurities from the cardboard. The fan box is designed as a ring-shaped cylindrical structure and is also mounted on the support cylinder, forming a compact connection with it. One end of the suction pipe branches into several branch pipes, each extending into a separate suction box. This allows all openings within each suction box to connect to the suction pipe via these branch pipes. The other end of the suction pipe passes through a support cylinder into a ring-shaped fan box, creating a continuous suction channel. An opening is located on the side of the fan box, where a negative pressure fan is installed, forming a complete suction power cycle. During operation, the cardboard to be laminated is conveyed to the cleaning component. Once activated, the negative pressure fan creates a negative pressure environment within the fan box. This negative pressure is transmitted to the suction boxes via the suction pipe and branch pipes. The suction boxes then suck up dust, paper scraps, and other impurities from the cardboard surface, completing the pre-cleaning process. The advantage of this design is that it automates the pre-cleaning of the cardboard before lamination using a dedicated cleaning component. This avoids defects such as bubbles and wrinkles caused by impurities trapped between the cardboard and the laminating layer, improving the quality of the laminated product. Furthermore, the integrated structural design ensures good compatibility between the cleaning component and existing laminating machines, eliminating the need for significant modifications to the machine itself.

[0006] Furthermore, the support frame and the support cylinder are connected by a bearing, with the outer ring of the bearing connected and installed to the support frame, and the inner ring of the bearing connected to the support cylinder.

[0007] The support frame and support cylinder are connected via bearings. Specifically, the outer ring of the bearing is fixedly installed to the support frame, while the inner ring of the bearing is tightly connected to the support cylinder, allowing the support cylinder to rotate relative to the support frame via the bearing. During operation, when the support cylinder needs to rotate to adjust the angle of the dust collection box or to achieve dynamic cleaning, the inner ring of the bearing rotates synchronously with the support cylinder, while the outer ring remains fixed to the support frame.

[0008] Furthermore, a gear ring is installed on the outer wall of the support cylinder, a drive motor is installed on the support frame, a drive shaft is installed at the output end of the drive motor through a coupling, a drive gear is installed on the drive shaft, and the drive gear meshes with the gear ring.

[0009] A gear ring is fixedly installed on the outer wall of the support cylinder, and the gear ring is coaxial with the support cylinder. A drive motor is installed on the support frame at the position corresponding to the gear ring. The output end of the drive motor is connected to the drive shaft through a coupling to ensure that the power of the drive motor can be stably transmitted to the drive shaft. A drive gear is fixedly installed on the drive shaft, and the drive gear meshes with the gear ring. During operation, after the drive motor starts, it drives the drive shaft to rotate, and the drive shaft drives the drive gear on it to rotate synchronously. Since the drive gear meshes with the gear ring on the support cylinder, the rotation of the drive gear is converted into the rotation of the gear ring, which in turn drives the support cylinder to rotate around its own axis. The rotation of the support cylinder drives the dust collection box on it to rotate synchronously. The active rotation of the support cylinder is achieved through gear transmission, so that the dust collection box can rotate around the axis of the support cylinder. This allows for multi-angle and all-round cleaning of the surface of the paperboard to be coated, avoiding the cleaning dead spots that exist in fixed dust collection methods and improving the thoroughness of cleaning. At the same time, the gear transmission has the characteristics of precise transmission ratio and stable power transmission, which can ensure that the rotation speed of the support cylinder is uniform, making the cleaning process more stable and controllable.

[0010] Furthermore, a first sieve plate is provided in the fan box, and the first sieve plate and the inner wall of the fan box form a storage cavity.

[0011] The blower box contains a first sieve plate, which, together with the inner wall of the blower box, forms a collection cavity, creating a space for collecting impurities. During operation, the negative pressure blower starts and generates negative pressure, drawing impurities from the cardboard surface into the blower box through the dust collection box, branch pipe, and suction pipe. When the airflow containing impurities passes through the first sieve plate, the first sieve plate intercepts and filters the impurities in the airflow. The impurities are blocked on the side of the first sieve plate near the suction pipe, i.e., inside the collection cavity. The filtered clean airflow then passes through the first sieve plate into the negative pressure blower and is discharged. The design of the first sieve plate and the collection cavity achieves centralized collection of impurities, preventing impurities from directly entering the negative pressure blower and causing wear on the blower's blades and other components, thus ensuring the normal operation and service life of the negative pressure blower. At the same time, the centralized collection of impurities facilitates subsequent unified cleaning, reducing the difficulty and frequency of equipment maintenance.

[0012] Furthermore, a baffle frame is installed on the dust collection box, and a second screen is installed on the baffle frame.

[0013] A baffle frame is fixedly installed on the dust collection box. The baffle frame adopts a structural design adapted to the dust collection box to ensure a firm installation. A second screen is installed on the baffle frame, covering the suction inlet of the dust collection box, forming a preliminary filtration structure for impurities. During operation, the negative pressure generated by the negative pressure fan creates suction at the dust collection box. When impurities on the surface of the cardboard are sucked in, they first pass through the second screen for filtration. Larger impurities, such as large pieces of paper scraps and debris, are blocked outside the dust collection box by the second screen, while smaller dust and fine paper scraps can pass through the second screen and enter the dust collection box. The second screen plays a preliminary filtration and protection role, effectively preventing large impurities from entering the suction pipe and causing pipe blockage, ensuring the smooth flow of the suction channel, and avoiding a decrease in cleaning efficiency due to pipe blockage.

[0014] Furthermore, a number of guide rollers are installed on the support frame.

[0015] Several guide rollers are installed on the support frame, and the guide rollers are rotatably connected to the support frame via a rotating shaft. The installation position of the guide rollers is adjusted to match the position of the dust collection box of the cleaning component, forming a cardboard conveying guide channel. During operation, the cardboard to be laminated is conveyed from the feeding end and first passes through several guide rollers on the support frame. The guide rollers guide and correct the conveying direction of the cardboard, so that the cardboard can be smoothly and accurately conveyed to the dust collection box of the cleaning component along the preset path. The setting of the guide rollers provides stable conveying guidance for the cardboard, effectively avoiding problems such as cardboard deviation and skewing during the conveying process, and ensuring that the cardboard can be precisely matched with the cleaning component.

[0016] The beneficial effects of this application are: 1. The cleaning component enables automated pre-cleaning before lamination, adsorbing impurities on the cardboard to avoid defects such as bubbles and wrinkles in the lamination process; 2. Gear transmission drives the support cylinder and dust collection box to rotate, enabling multi-angle and all-round cleaning and avoiding fixed dust collection dead corners; 3. Precise gear ratios ensure a stable and controllable cleaning process. Attached Figure Description
