Description

Technical Field

[0001] This application relates to the field of SPC flooring production technology, specifically to a surface brightening treatment apparatus for SPC flooring production. Background Technology

[0002] SPC flooring, also known as stone-plastic composite flooring, is made by high-temperature extrusion of calcium powder and thermoplastic polymer materials, combining the advantages of both wood and plastic.

[0003] In the production process of SPC flooring, in order to make its surface gloss meet the requirements, an SPC flooring surface brightening treatment device is usually required. The SPC flooring surface brightening treatment device is a special equipment used in the SPC (stone plastic composite) flooring production line. Its core function is to perform automated spraying treatment (such as spraying, UV coating, etc.) on the flooring surface to achieve improved surface gloss, enhanced decorative effect, or functional protection (such as wear resistance and stain resistance).

[0004] For example, patent CN214811932U discloses a UV surface brightening spraying device for SPC floor production. This patent sets up a U-shaped frame and spraying units, and fixes wedge blocks to the inner sides of both ends of the U-shaped frame. The wedge blocks are fixed to the outer sides of the two side plates by bolts. After the bolts are loosened, the movable U-shaped frame is located at the top of the conveying mechanism. Multiple spraying units are movably connected to the top of the U-shaped frame, and the spraying units are located in the middle of the device, thereby performing spraying operations on the SPC floor.

[0005] However, in the surface gloss treatment of SPC (stone-plastic composite) flooring, double-sided spraying is a key process to improve the product's aesthetics and durability. Traditional production processes usually adopt a segmented operation: first, the flooring is sprayed on one side via a conveyor line, and after the paint has cured, the flooring is manually moved to the flipping area, manually turned around, and then reloaded for spraying on the other side. The manual flipping process requires interrupting continuous production, limiting the daily processing capacity of a single production line. Moreover, the flipping time increases with the size of the flooring, necessitating the setting of an additional transfer buffer area. Furthermore, the repeated loading operation reduces the utilization rate of the equipment.

[0006] Therefore, it is necessary to provide surface brightening equipment for SPC flooring production to solve the above problems.

[0007] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

Detailed Implementation

[0033] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0035] like Figures 1-2 As shown, this application provides a surface brightening treatment device for SPC floor production. The surface brightening device is mainly installed on the SPC floor production line and is used to perform spraying operations on the surface of SPC floor. Specifically, the surface brightening device includes a frame 1 and spraying components 4 installed on both sides of the frame 1. It can be understood that the SPC floor is located between the two sets of spraying components 4 so as to realize the spraying operation on both sides of the SPC floor.

[0036] The spraying assembly 4 includes a slide rail 40 and a spraying robotic arm 41. The spraying robotic arm 41 is prior art. For details, please refer to the spraying robotic arm disclosed in the patent with publication number CN216094463U. It will not be described in detail in this application.

[0037] Furthermore, the spraying robotic arm 41 is slidably mounted on the slide rail 40, thereby making the spraying robotic arm 41 suitable for moving on the slide rail 40. At the same time, the spraying robotic arm 41 is equipped with a spray nozzle so that it can perform spraying operations on the SPC floor.

[0038] Meanwhile, a transmission mechanism 2 is installed on the frame 1. The transmission mechanism 2 includes a first motor 22 fixedly installed on one side of the upper end of the frame 1, and sprockets 20 are rotatably installed on both sides of the upper end of the frame 1. The output end of the first motor 22 is fixedly connected to one side of the sprocket 20, and a chain 21 is connected between the two sprockets 20.

[0039] Furthermore, at least two sets of fixing frames 3 are suspended on the chain 21. The fixing frames 3 are used to fix and install the SPC floor. Thus, the first motor 22 can drive the chain 21 to rotate on one side of the upper end of the frame 1 by driving the sprocket 20, thereby realizing the purpose of the transmission mechanism 2 to transport the SPC floor.

[0040] Example 1:

[0041] To achieve double-sided spraying of SPC flooring, such as Figure 1 and Figures 3-4 As shown, the fixed frame 3 includes a fixed frame 30 suspended on the chain 21 and a movable frame 32 rotatably disposed inside the fixed frame 30. The movable frame 32 is used to clamp the SPC floor.

[0042] Specifically, the fixing frame 30 includes a connecting frame 300 fixedly installed at the lower end of the chain 21, and fixing rods 301 are fixedly installed at both ends of the connecting frame 300 so as to provide a stable support foundation for subsequent SPC floor installation and transportation;

[0043] In order to enable stable installation of SPC flooring, the movable frame 32 includes two sets of rotating rods 302 disposed inside the fixed rod 301, which are initially set vertically.

[0044] Two sets of abutment plates 303 are slidably arranged on the two sets of rotating rods 302. It can be understood that a collar (not shown in the figure) is provided at both ends of the two sets of abutment plates 303. The collar is sleeved on the outside of the rotating rod 302, so that the two sets of abutment plates 303 can move closer or further away from each other along the length of the rotating rod 302 under the action of external force, relying on the cooperation between the collar and the rotating rod 302.

[0045] To provide automatic clamping force, two sets of springs 304 are fixedly installed between the two sets of rotating rods 302. The other ends of these two sets of springs 304 are fixedly connected to the two sets of abutment plates 303 respectively. Thus, when the worker pulls the two sets of abutment plates 303 away from each other, the springs 304 on both sides are stretched and stored. After the abutment plates 303 are released, the springs 304 retract and reset, and drive the two sets of rotating rods 302 to reset.

[0046] Meanwhile, a slot 305 is provided on each of the two sets of abutment plates 303. The slot 305 is adapted to the thickness of the SPC floor. A buffer strip (not shown in the figure) is embedded in the slot 305. In the initial state, the distance between the two sets of abutment plates 303 is less than the length (or width) of the SPC floor. When it is necessary to clamp the SPC floor, the staff pulls the two sets of abutment plates 303 away from each other, and then puts the two ends of the SPC floor into the two sets of slots 305.

[0047] When the staff releases the pressure, the two sets of abutment plates 303 move closer to each other under the action of spring 304 and clamp the SPC floor to ensure that it is not easy to shift or shake during the transmission process.

[0048] During operation, the worker first operates the holding plate 303 at the loading station to clamp and fix both ends of the SPC flooring onto the movable frame 32. Then, the transmission mechanism 2 is started, and the machine moves along the frame 1 to the spraying component 4 area under the drive of the chain 21. When the fixed frame 3 reaches the working position of the two spraying robotic arms 41, the transmission mechanism 2 stops. At this time, the two spraying robotic arms 41 installed on the slide rail 40 start simultaneously. The spraying robotic arms 41 move along their respective slide rails 40, and the nozzles on them are aimed at the front and back of the SPC flooring respectively. During the movement, the spraying robotic arms 41 continuously and evenly spray brightener or other treatment liquid onto the two surfaces of the SPC flooring.

[0049] After the spraying is completed, the spraying robot arm 41 is reset and the transmission mechanism 2 is restarted, which transports the sprayed SPC floor to one side of the frame 1. At this time, the workers disassemble the sprayed SPC floor and then start the transmission mechanism 2 to transport the fixed frame 3 to the loading station for loading. At the same time, the loaded fixed frame 3 is transported to the working area of ​​the spraying component 4. This cycle is repeated to achieve simultaneous spraying of both sides of the SPC floor in continuous production.

[0050] Example 2: To address situations where different compositions or functional gloss agents need to be sprayed onto both sides of the floor, such as... Figure 1 and Figures 5-6 As shown, a fixed base 320 is fixedly installed on one side of the fixed rod 301, and a second motor 321 is installed on the fixed base 320. A rotating shaft 322 is rotatably installed on the fixed rod 301. One end of the rotating shaft 322 is fixedly connected to the rotating rod 302, and the other end passes through the fixed rod 301 and is fixedly connected to the output end of the second motor 321.

[0051] The SPC floor can be flipped by starting the motor to drive the rotating rod 302. After one side of the SPC floor is coated, the SPC floor can be flipped by starting the second motor 321, and then the other side can be coated. This avoids cross-contamination between different paints during the coating process.

[0052] When working, the staff first use the support plate 303 to clamp and fix both ends of the SPC floor to the movable frame 32;

[0053] Then, the transmission mechanism 2 is activated, and the SPC floor is moved to the working area of ​​the spraying components 4 on both sides of the middle of the frame 1. The spraying process begins. At this time, the SPC floor is in a vertically suspended state, and one side of the SPC floor is facing the spraying component 4 on one side. The spraying robot arm 41 on that side moves on the slide 40 according to the preset program. At the same time, the nozzle of the spraying robot arm 41 is turned on, and the brightening agent is evenly sprayed onto the surface of the SPC floor.

[0054] After one side is sprayed, the second motor 321 is started to drive the movable frame 32 to rotate so that the SPC floor is flipped. After flipping, the SPC floor is moved to the other side. At this time, another set of spraying components 4 sprays different components or functions of brighteners onto the other side of the SPC floor.

[0055] Finally, the SPC flooring with double-sided spraying completed is transported back to the unloading station, where workers can remove it by releasing the holding plate 303.

[0056] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
