Description

Technical Field

[0001] This utility model relates to the field of coating machines, and more particularly to a coating machine for plastic flooring. Background Technology

[0002] Plastic flooring is an elastic floor decoration material made from polyvinyl chloride resin as the main raw material, with the addition of plasticizers, stabilizers, pigments and other auxiliary materials, through calendering, coating and lamination processes. In the lamination process between the layers of plastic flooring, a coating machine is usually used to coat and press the layers together. As shown in the heat-insulating plastic flooring coating machine disclosed on the China Patent Network (announcement number CN218691103U), this type of device uses a slow-speed motor to drive a pressing roller that can be adjusted vertically. It uses a ring threaded connection to a threaded rod, and uses the ring and connecting rod to drive the sleeve to slide up and down on the guide rod, thereby realizing the adjustment of the pressing roller height. It can coat and press heat-insulating plastic flooring of different thicknesses during the production of heat-insulating plastic flooring.

[0003] However, the aforementioned patented and existing plastic flooring coating machines still have some shortcomings: Existing methods using lifting and adjusting components to act on the pressing rollers to achieve coating and pressing of plastic flooring of different thicknesses, while applicable to coating and pressing processes of plastic flooring of varying thicknesses, typically rely solely on the roller pressure during the pressing process. This results in a relatively simple pressing action, short pressing contact, and an inability to guarantee the pressing state. Therefore, those skilled in the art have provided a plastic flooring coating machine to address the problems mentioned in the background section. Utility Model Content

[0017] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 This utility model provides a technical solution for a coating machine for plastic flooring: a coating machine for plastic flooring includes a bottom support plate 1 and a top support plate 2 that are horizontally opposite each other. Two sets of first supports 7 are provided between the bottom support plate 1 and the top support plate 2. Each set of first supports 7 has two pairs. At least one set of first pressure rollers 8 is rotatably installed between the two pairs of first supports 7. A second pressure roller 9 is slidably installed above the first pressure roller 8. A lifting adjustment component is provided above the top support plate 2 to drive the second pressure roller 9 to move up and down toward the first pressure roller 8. By using the lifting adjustment component as a driving source, the second pressure roller 9 is driven to move closer to the first pressure roller 8. By adjusting the distance between the two sets of pressure rollers, the coating and pressing process of plastic flooring with different thicknesses can be adapted.

[0019] Furthermore, a second support 10 is provided between the two sets of first supports 7. The second support 10 has two pairs, and a tension roller 11 is slidably installed between the two pairs of second supports 10. The lifting and adjusting component is also used to drive the tension roller 11 to move up and down. While the lifting and adjusting component adjusts the distance between the two sets of pressure rollers, it also drives the tension roller 11 to move up and down simultaneously. By using the tension roller 11 to tension the plastic flooring, the plastic flooring is always kept in a taut state during transportation, maintaining its continuous pressing state after transportation. This increases the coating and pressing time and also assists in re-coating and pressing, performing a multi-point pressing process.

[0020] As a further embodiment, the lifting adjustment assembly includes an electric push rod 3 located above the top support plate 2, and a first support rod 4 located at the telescopic end of the electric push rod 3. The two ends of the first support rod 4 are provided with second support rods 5 that drive the first pressure roller 8 and the tension roller 11 to move up and down. The lifting adjustment assembly also includes a first slide 14 slidably installed inside the first bracket 7. The first slide 14 is rotatably connected to the second pressure roller 9, and a first guide rod 15 is fixedly connected above the first slide 14. By using the lifting drive of the electric push rod 3, the first guide rod 15 is pushed to move up and down under the arm force transmission of the first support rod 4 and the second support rod 5, thereby pushing the first slide 14 to move up and down along the first bracket 7, moving the second pressure roller 9 closer to the first pressure roller 8, so that a suitable distance is maintained between the second pressure roller 9 and the first pressure roller 8 to adapt to the coating and pressing process of the plastic flooring.

[0021] It should be noted that the lifting and adjusting assembly also includes a second slide 18 slidably installed inside the second bracket 10. The second slide 18 is fixedly connected to the tension roller 11, and a second guide rod 19 is fixedly connected above the second slide 18. When the electric push rod 3 is lifted and lowered, the second slide 18 is driven to move up and down along the second bracket 10 through the second guide rod 19, which moves the tension roller 11 down and presses down on the conveyed plastic flooring to tighten it. On the one hand, the plastic flooring is pressed again, and on the other hand, the plastic flooring is kept in a real-time tensioned state to maintain its pressing characteristics after pressing and ensure the coating pressing quality.

[0022] Furthermore, one end of the roller shaft of the first pressure roller 8 is provided with a first drive gear 12, and one end of the roller shaft of the second pressure roller 9 is provided with a second drive gear 13 that can mesh with the first drive gear 12. A drive motor 6 is provided on one side of one set of first pressure rollers 8, and a transmission combination of pulley 16 and transmission belt 17 is provided in the axial direction of the two sets of first pressure rollers 8. Using the drive motor 6 as the drive source, the corresponding first pressure roller 8 is driven to rotate under the transmission combination of pulley 16 and transmission belt 17. During the rotation of the first pressure roller 8, the first drive gear 12 is driven to rotate, and the meshing of the first drive gear 12 and the second drive gear 13 drives the second pressure roller 9 to rotate relative to each other, so that the first pressure roller 8 and the second pressure roller 9 roll and convey the plastic flooring in a counter-rotating manner.

[0023] In addition to the above, the tension roller 11 is provided with a limiting guide structure along its axial direction. The limiting guide structure includes a lead screw 23 rotatably installed inside the tension roller 11. The lead screw 23 is provided with two sets of slides 24 along its axial direction, and a limiting ring 21 is provided on the outside of the slides 24 and fitted onto the tension roller 11. One end of the lead screw 23 is provided with an adjustment knob 22. The lead screw 23 is divided by a center line, and both sides of the center line are provided with positive and negative threads that are adapted to the two sets of slides 24. Before the plastic flooring is coated and pressed, the adjustment knob 22 can be pre-rotated to drive the lead screw 23 to rotate. The positive and negative threads on the lead screw 23 are used to push the two sets of slides 24 to move in opposite directions along its axial direction, thereby adjusting and aligning the distance between the two sets of limiting rings 21 so that the distance between them matches the width of the plastic flooring. This serves as a guide and limit during the conveying of the plastic flooring, preventing tilting or deviation during conveying.

[0024] It should be noted that the tension roller 11 has a clearance slot 20 along its axial direction to provide space for the slide 24 to move. The clearance slot 20 provides the space required for the slide 24 to push the limiting ring 21 to move. The clearance slot 20 also creates an opening on the tension roller 11. Therefore, by fixing the tension roller 11 to the second slide 18, the plastic flooring will not come into contact with the clearance slot 20 when it is pulled by the tension at the bottom of the tension roller 11, so that the plastic flooring always smoothly transitions along the roller surface of the tension roller 11.

[0025] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
