Description

Technical Field

[0001] The invention relates to the technical field of plate laminating, in particular to a PVC plate laminating machine. Background Art

[0002] PVC board is a board with a honeycomb mesh structure in cross section made of PVC as raw material. It is a vacuum plastic-absorbing film. It is used for surface packaging of various panels, so it is also called decorative film or adhesive film. It is used in many industries such as building materials, packaging, and medicine. Among them, the building materials industry accounts for the largest proportion, which is 60%, followed by the packaging industry, and there are several other small-scale application industries. It can be divided into soft PVC and hard PVC according to the degree of hardness and softness, and can be divided into PVC crusted foam board and PVC free foam board according to the production process.

[0003] Existing Chinese patent CN211195244U discloses a high-quality laminating device for PVC wall panels. The machine housing is fully enclosed, allowing transportation and extrusion lamination to be carried out in a closed environment. Before extrusion lamination, a blower pipe on the top of the conveyor roller blows away dust, hair, fibers and other debris on the surface of the wall panel to be laminated, keeping the surface of the wall panel clean and preventing dust, hair, fibers and other debris in the air from being trapped between the film and the cardboard during the lamination process, forming bubbles. This improves the lamination quality and solves the problem of dust, hair, fibers and other debris being easily trapped between the film and the cardboard during lamination in existing PVC wall panel laminating devices, forming bubbles. However, during use of the above-mentioned device, since the blow pipe is installed inside the machine casing, when the blow pipe blows away dust, hair, fibers, etc. on the PVC wall panel, the blown impurities will fall into the coating working cavity of the machine casing, and it is inconvenient to manually clean the impurities in the cavity of the machine casing, resulting in a poor coating environment inside the machine casing. In addition, when the blow pipe is in operation, the impurities accumulated in the machine casing may be blown onto the film, which will cause impurities to be easily mixed between the film and the PVC wall panel to form bubbles during coating.

Under the action of the first spring in the dust removal structure, the silicone sticky sleeve can fit tightly with the PVC sheet. During the process of the conveying mechanism conveying the PVC sheet, the PVC sheet drives the silicone sticky sleeve to rotate. During the rotation, the silicone sticky sleeve can adhere to impurities such as hair, fiber and dust on the surface of the PVC sheet, which is beneficial to cleaning the surface of the PVC sheet. In addition, since impurities such as hair adhere to the surface of the silicone sticky sleeve, the impurities will not fly around when cleaning the impurities on the surface of the sheet.

[0014] 2. The present invention installs a flushing structure. When the PVC sheet is separated from the dust removal structure as a whole and the coated part is moved out from under the coating mechanism, one end of the coated sheet will press against the baffle. When the conveying mechanism continues to convey the sheet, the sheet will push the piston through the baffle. The piston will send the warm water in the sleeve into the spray pipe and spray it on the silicone sticky sleeve through the spray head. Spraying the silicone sticky sleeve with warm water is beneficial to automatically remove impurities adhered to the surface of the silicone sticky sleeve. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only 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 making creative efforts are within the scope of protection of the present invention. Example 1

[0018] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The figure shows a PVC sheet laminating machine, which is used to transport PVC sheets. A laminating mechanism 2 for laminating the surface of the PVC sheets is fixedly installed on the upper end of the conveying mechanism 1. The sheet body 12 is conveyed on the conveying mechanism 1, and a protective cover 3 is fixedly installed on the feeding end of the laminating mechanism 2. Several groups of fans 4 with equal distances are fixedly embedded on the top of the protective cover 3; a dust removal structure 5 for removing impurities such as dust and fiber attached to the surface of the PVC sheet is installed at the upper end of the conveying mechanism 1 and is located on the inner side of the protective cover 3. A flushing structure 6 for flushing the dust removal structure 5 is installed on the right side of the laminating mechanism 2.

[0019] See also Figure 4 and Figure 5 The dust removal structure 5 includes a roller 501 installed on the upper side of the conveying mechanism 1, and a silicone sticky sleeve 502 is fixedly mounted on the outer side of the roller 501. The upper end of the conveying mechanism 1 is located at both ends of the roller 501 and two symmetrically distributed support columns 503 are fixedly mounted. The support columns 503 are internally embedded with sliders 504 that can move up and down. The outer side of the roller 501 is located at both ends and is fixedly mounted with bearings 505.

[0020] See also Figure 5 The roller 501 is rotatably connected to the slider 504 through the bearing 505. A first spring 506 is fixedly installed at the center of the lower end of the slider 504, and the lower end of the first spring 506 is fixedly connected to the support column 503. The roller 501 and the slider 504 are slidably connected to the support column 503 through the limiting straight groove 507.

[0021] The working principle of the device can remove impurities attached to the surface of PVC plates: the plate is placed on the conveying mechanism 1, and the conveying mechanism 1 conveys the plate body 12 to the dust removal structure 5. The thickness of the plate body 12 will drive the roller 501 to move upward, and under the drive of the first spring 506, the silicone sticky sleeve 502 will fit tightly with the surface of the plate body 12. In the process of the conveying mechanism 1 driving the plate body 12 to move, the plate body 12 will drive the roller 501 to rotate, and the silicone sticky sleeve 502 will be squeezed and rotated on the surface of the plate body 12, which is conducive to the adhesion of hair, fiber, dust and other impurities attached to the surface of the plate 12 to the silicone sticky sleeve 502, which is conducive to cleaning the plate body 12, and the impurities adhered to the silicone sticky sleeve 502 will not fly around, which can effectively prevent the impurities from flying into the coating mechanism 2. Example 2

[0022] See also Figure 5 、 Figure 6 and Figure 7 This embodiment further explains Example 1. The flushing structure 6 includes a spray pipe 601 installed directly above the silicone sticky wool sleeve 502. The lower end of the spray pipe 601 is fixedly installed with several groups of spray heads 602 that are interconnected and distributed at equal distances. The outer side of the spray pipe 601 is fixedly sleeved with a positioning seat 603 at both ends, and the connection between the positioning seat 603 and the support column 503 is a fixed connection. Both ends of the spray pipe 601 are fixedly installed with a first soft conduit 604 that is interconnected.

[0023] See also Figure 6 The end of the first soft tube 604 is fixedly connected to a sleeve 605 that is interconnected with it. A piston 606 that can move left and right is installed inside the sleeve 605. A push rod 607 is fixedly embedded in the center of the left end face of the piston 606. A baffle 608 is installed on the left side of the sleeve 605. The connection between the two push rods 607 and the baffle 608 is a fixed connection. The outer side of the push rod 607 is located between the sleeve 605 and the baffle 608 and is movably connected with a second spring 609.

[0024] See also Figure 2 and Figure 7 A second soft conduit 610 communicating with each other is fixedly installed on the outside of the sleeve 605, and a check valve 611 is fixedly installed on the outside of the first soft conduit 604 and the second soft conduit 610 near the sleeve 605. A water tank 612 is installed on the lower side of the conveying mechanism 1. The water tank 612 passes through the water tank 612 and is communicated with the water tank 612. A heating plate 613 is fixedly installed at the center of the inner bottom of the water tank 612, and a water inlet pipe 614 communicating with each other is fixedly installed on the outside of the water tank 612.

[0025] In this embodiment: after the plate body 12 is separated from the dust removal structure 5, one end of the coating will be against the baffle 608 during the conveying process of the conveying mechanism 1. Then, as the plate body 12 continues to move, the plate body 12 can push the piston 606 to the right through the baffle 608 and the push rod 607. Under the action of the check valve 611 on the second soft conduit 610, the piston 606 can transport the warm water stored in the sleeve 605 to the spray pipe 601 through the first soft conduit 604 during the movement to the right, and then spray it on the silicone sticky wool sleeve 502 through the spray head 602. By spraying the silicone sticky wool sleeve 502 with warm water, the dust adhering to its surface can be removed. Dust, hair and other impurities, then the plate body 12 that is against the baffle 608 and coated is removed, and the baffle 608 and the piston 606 will move to the left and reset under the drive of the second spring 609. Under the action of the check valve 611 on the first soft tube 604, when the piston 606 moves to the left, the warm water in the water tank 612 is sucked into the sleeve 605 through the second soft tube 610, which is beneficial for rinsing the silicone wool cover 502 once after coating a plate body 12, thereby ensuring the adhesion of the silicone wool cover 502, and after the silicone wool cover 502 is rinsed, the fan 4 can run to dry the silicone wool cover 502. Example 3

[0026] See also Figure 8 and Figure 9 , this embodiment further explains other embodiments, the outer side of the sleeve 605 is fixedly sleeved with two symmetrically distributed fixing rings 7, the lower end of the fixing ring 7 is fixedly installed with a fixing plate 8, the lower end surface of the fixing plate 8 is movably fitted with the upper end surface of the frame of the conveying mechanism 1, and the upper end of the fixing plate 8 is fixedly installed with four groups of positioning components 9 distributed in an array. The upper end of the conveying mechanism 1 is located on the outer side of the fixing plate 8 and is fixedly installed with two symmetrically distributed limiting guide rails 10. The positioning component 9 includes a positioning sleeve 901 that penetrates the fixing plate 8 and is fixedly connected to the fixing plate 8. The connection between the positioning sleeve 901 and the limiting guide rail 10 is a sliding connection, and the upper end of the positioning sleeve 901 is fixedly connected with a limiting ring 902.

[0027] See also Figure 8 and Figure 9The positioning sleeve 901 and the limiting ring 902 are internally movably installed with a connecting rod 903 that can move up and down. A knob 904 is installed on the upper end of the connecting rod 903. The knob 904 is rotatably connected to the connecting rod 903 through a positioning shaft 905, and the positioning shaft 905 deviates from the center of the knob 904. A rubber pad 906 is fixedly installed on the lower end of the connecting rod 903. The outer side of the connecting rod 903 is located between the limiting ring 902 and the rubber pad 906 and is movably sleeved with a third spring 907. A reserved straight groove is provided on the upper end surface of the frame of the conveying mechanism 1 directly below the rubber pad 906. Several groups of convex teeth 11 distributed at equal distances are provided in the straight groove of the frame of the conveying mechanism 1, and the connection between the rubber pad 906 and the convex tooth 11 is a movable abutment.

[0028] In this embodiment: when it is necessary to change the position of the sleeve 605 according to the length of the plate, the user rotates the knob 904 to a vertical state. Since the positioning shaft 905 deviates from the center of the knob 904, when the knob 904 is rotated to a vertical state, the rubber pad 906 can be driven by the connecting rod 903 to move up and disengage from the convex tooth 11. After adjusting the positions of the two sleeves 605, the knob 904 is rotated to a horizontal state. At this time, the rubber pad 906 is driven by the third spring 907 to cling to the convex tooth 11 on the frame of the conveying mechanism 1, which helps to prevent the fixed plate 8 from moving on the frame of the driving mechanism 1, making it more convenient to adjust the position of the sleeve 605.
