Description

Technical Field

[0001] This utility model relates to the field of stone plastic flooring production technology, specifically to a back coating bonding device for stone plastic flooring production. Background Technology

[0002] Stone plastic flooring (PVC stone plastic flooring) production technology uses polyvinyl chloride (PVC) resin as the core, integrating formula design and multiple processes to create a flooring material that combines practicality and decoration. It uses PVC resin as the base material, combined with calcium carbonate (60%-80%) to increase hardness, plasticizers such as dioctyl phthalate (DOP) to adjust flexibility, calcium and zinc stabilizers to ensure thermal stability, and pigments to give color. Some products add antibacterial and flame retardant components to achieve functional upgrades. In the production of stone plastic flooring, the existing back coating and bonding equipment has many shortcomings.

[0003] For example, an automatic laminating device for composite film on floor surfaces, as described in application number CN202421820246.9, includes a housing, which is a hollow rectangular box with open front and rear walls. A cylinder is fixedly connected to the top of the housing cavity, and a cutter is fixedly connected to the bottom of the cylinder. A laminating roller is also rotatably connected inside the housing cavity. A drive shaft is symmetrically rotatably connected inside the housing cavity, and a conveyor belt is driven through the walls of the symmetrical drive shaft. A limiting structure is included, which can fix flooring of different sizes to the top of the conveyor belt. The limiting structure includes clamping rods, connecting plates, and screws. The clamping rods are symmetrically arranged inside the housing cavity, the connecting plates are fixedly connected to the top of each clamping rod, and the screws are rotatably connected to the top of the housing cavity. The symmetrical clamping rods can clamp the sides of the flooring. However, this back-coating laminating device is prone to misalignment during lamination, affecting product quality and making it difficult to adapt to stone plastic flooring of different materials and thicknesses.

[0004] Therefore, in view of this, we have studied and improved the existing structure to propose a back coating bonding device for the production of stone plastic flooring. Utility Model Content

[0005] The purpose of this invention is to provide a back coating bonding device for the production of stone plastic flooring, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a back coating bonding device for the production of stone plastic flooring, comprising a coating tank and a coating mixing mechanism. The coating tank is provided with a coating mixing mechanism, which includes a mixing blade disposed within the coating tank. A mixing shaft is fixedly connected to the inner surface of the mixing blade, and one end of the mixing shaft is fixedly connected to the output end of a motor. A transmission belt is provided on the outer surface of the output end of the motor, and a coating roller is rotatably connected to the inner surface of the transmission belt.

[0007] Preferably, a support plate is fixedly connected to one side of the motor, and a discharge chamber is fixedly connected to the top of the paint tank.

[0008] Preferably, a conveying pipe is fixedly connected to the top of the discharge chamber, and a storage box is fixedly connected to one end of the conveying pipe.

[0009] Preferably, an electric lifting rod is fixedly connected to the bottom of the support plate, and a frame is provided at the bottom of the coating roller, with a guide mechanism inside the frame.

[0010] Preferably, the guiding mechanism includes a slide groove located inside the frame, a slider is slidably connected inside the slide groove, a fixed rod is fixedly connected to the top of the slider, and a guide wheel is rotatably connected to the outer surface of the fixed rod.

[0011] Preferably, the frame is rotatably connected to a conveying roller, and the outer surface of the motor is fixedly connected to a shock-absorbing seat.

[0012] Preferably, the bottom of the electric lifting rod is fixedly connected to a support base plate, and a control box is fixedly connected to one side of the support base plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model achieves the dual functions of coating homogenization and efficient coating through the setting of a coating mixing mechanism and the coordinated operation of multiple components. When the stone plastic flooring passes by, the rotating coating roller carries out the uniformly mixed coating. The uniform coating is achieved by the contact between the roller surface and the back of the flooring. The stirring blade continuously stirs to maintain the uniformity of the coating, and the stable rotation of the coating roller ensures that the coating thickness is consistent. The two work together to improve the quality and production efficiency of the back coating of stone plastic flooring from raw material homogenization to coating and forming.

[0015] 2. This utility model, through the setting of a guiding mechanism, clamps both sides of the stone plastic flooring with appropriate pressure. When the stone plastic flooring is conveyed, its precise guiding effect corrects the deviation of the stone plastic flooring in real time, ensuring that each stone plastic flooring is accurately aligned when entering the coating bonding area. This effectively avoids bonding defects caused by positional deviations and significantly improves the coating bonding accuracy and finished product quality. Attached Figure Description

[0021] 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.

[0022] like Figures 1-3 As shown, a back coating bonding device for stone plastic flooring production includes a coating tank 1 and a coating mixing mechanism 2. The coating tank 1 is equipped with the coating mixing mechanism 2, which includes a mixing blade 201 positioned within the coating tank 1. A mixing shaft 202 is fixedly connected to the inner surface of the mixing blade 201, and one end of the mixing shaft 202 is fixedly connected to the output end of a motor 203. A transmission belt 204 is provided on the outer surface of the output end of the motor 203, and a coating roller 205 is rotatably connected to the inner surface of the transmission belt 204. The coating roller 205 is horizontally positioned within the coating tank 1, with a portion of its surface exposed above the outlet of the coating tank 1. Multiple sets of mixing blades 201 are evenly distributed on the outer surface of the mixing shaft 202 to stir the coating in the coating tank 1, preventing pigments and additives in the coating from settling, ensuring uniform coating composition, and improving the quality of the back coating.

[0023] like Figure 1 As shown, a support plate 3 is fixedly connected to one side of the motor 203, and a discharge chamber 4 is fixedly connected to the top of the paint tank 1. A conveying pipe 5 is fixedly connected to the top of the discharge chamber 4, and a storage box 6 is fixedly connected to one end of the conveying pipe 5. The storage box 6 is used to store paint, and a pressure pump is installed inside the storage box 6 to convey the paint to the discharge chamber 4 through the conveying pipe 5. The discharge chamber 4 makes the paint evenly distributed inside the paint tank 1.

[0024] Furthermore, an electric lifting rod 7 is fixedly connected to the bottom of the support plate 3, and a frame 8 is provided at the bottom of the coating roller 205. A guide mechanism 9 is provided inside the frame 8. The guide mechanism 9 includes a slide groove 901 opened inside the frame 8, and a slider 902 is slidably connected inside the slide groove 901. A fixing rod 903 is fixedly connected to the top of the slider 902, and a guide wheel 904 is rotatably connected to the outer surface of the fixing rod 903. The electric lifting rod 7 is located at the bottom of the two sets of support plates 3, which facilitates the adjustment of the height of the coating roller 205 according to the different thicknesses of the stone plastic flooring, ensuring that the coating roller 205 fits tightly with the stone plastic flooring. During the conveying process of stone plastic flooring of different sizes, the guide wheel 904 ensures that the stone plastic flooring is conveyed along a fixed path to achieve precise alignment. When the guide wheel 904 contacts the stone plastic flooring, the slider 902 slides inside the slide groove 901, which facilitates the clamping and guiding of stone plastic flooring of different sizes.

[0025] Furthermore, the frame 8 is internally connected to a conveying roller 10, and the outer surface of the motor 203 is fixedly connected to a shock-absorbing seat 11. The bottom of the electric lifting rod 7 is fixedly connected to a support base plate 12, and a control box 13 is fixedly connected to one side of the support base plate 12. The shock-absorbing seat 11 reduces the vibration amplitude of the motor 203 during operation and extends the service life of the motor 203. The conveying roller 10 continuously conveys multiple sets of stone plastic flooring, increasing processing efficiency. The control box 13 controls the operation of the device components.

[0026] Working Principle: When using this back coating bonding device for SPC flooring production, firstly, paint is injected into the storage tank 6, and the internal pressure pump is started. The paint in the storage tank 6 is then transported to the discharge chamber 4 through the conveying pipe 5, and then evenly conveyed into the paint tank 1. After an appropriate amount of paint is injected into the paint tank 1, the control box 13 is operated to start the rotation of the conveying rollers 10 inside the frame 8. The SPC flooring that needs coating is placed on top of the conveying rollers 10, and then the conveying rollers 10 drive the SPC flooring to be conveyed along the fixed path of the guide mechanism 9. The guide wheels 904 outside the fixed rod 903 clamp the SPC flooring. When dealing with SPC flooring of different sizes... The slider 902 drives the guide wheel 904 to slide inside the chute 901. When the stone plastic flooring is conveyed to the bottom of the coating roller 205, the motor 203 of the coating mixing mechanism 2 is started. The motor 203 drives the mixing blades 201 on the outer surface of the mixing shaft 202 to mix the coating. At the same time, the motor 203 drives the coating roller 205 on the inner surface of the transmission belt 204 to start rotating. The coating roller 205 with coating is put into contact with the stone plastic flooring to perform coating bonding work. Finally, when the motor 203 rotates, the shock absorber 11 reduces the vibration amplitude of the motor 203 and extends the service life of the motor 203. This is the working principle of the back coating bonding device for stone plastic flooring production.
