Description

Technical Field

[0001] This utility model belongs to the technical field of co-extruded wood-plastic composite splicing devices, specifically a co-extruded wood-plastic composite auxiliary splicing device. Background Technology

[0002] Co-extruded wood-plastic composite (WPC) is a composite material that combines two or more different types of plastics and wood flour through a co-extrusion process to form a multi-layered WPC product. This material typically consists of a core layer and an outer layer. The core layer is primarily composed of a mixture of wood flour and recycled plastic, while the outer layer is a pure plastic protective layer.

[0003] Co-extruded wood-plastic composites are mostly used outdoors. When used as a fence, they need to be used with posts. By installing two posts on the ground and then installing several co-extruded wood pieces between the two posts, a fence is formed.

[0004] In actual installation of co-extruded wood-plastic composites (WPC), the WPC needs to be installed into the grooves of the uprights. To better stabilize the WPC, the width of the grooves is generally similar to the thickness of the WPC. This results in relatively narrow grooves, making it difficult for workers to quickly insert the WPC. They need to constantly adjust the WPC to fit into the groove. Furthermore, because the WPC has a certain length, when one end is inserted into the groove of an upright, the other end also needs to be adjusted separately. This significantly increases the difficulty of installation and reduces efficiency.

[0005] Therefore, this utility model provides a co-extruded wood-plastic auxiliary splicing device. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: The co-extruded wood-plastic auxiliary splicing device of this utility model includes a co-extruded wood board and a column. A groove is opened on one side of the column, and the co-extruded wood board is inserted into the groove. Two symmetrically arranged guide blocks are fixedly installed on the top of the column. One side of the guide block is arc-shaped, and several guide posts are rotatably connected to the arc-shaped surface of the guide block. Two symmetrically arranged rectangular grooves are opened in the column. The rectangular grooves are connected to the groove. A rectangular block is slidably connected in the rectangular groove by a spring. Sandpaper is fixedly installed on the side of the rectangular block away from the spring.

[0008] Furthermore, the top and bottom of the rectangular block are rounded, and guide wheels are rotatably connected to the rounded corners of the rectangular block.

[0009] Furthermore, a hollow elastic block is fixedly installed inside the rectangular groove. The elastic block is pre-stored with lubricant. One side of the elastic block is equipped with an inlet pipe that is connected to the interior and has a one-way valve. The column has a receiving groove that is connected to the slide groove. One side of the elastic block is fixedly installed with a guide pipe that is connected to the interior and has a one-way valve. One end of the guide pipe is located in the receiving groove.

[0010] Furthermore, four pressure plates are fixedly installed on the side of the rectangular block near the spring, with the four pressure plates arranged in pairs and the pressure plates being arc-shaped.

[0011] Furthermore, a hollow storage frame is fixedly installed inside the storage groove, and the end of the guide tube away from the elastic block is connected to the inside of the storage frame. Several liquid outlet holes are opened on the side of the storage frame near the slide groove.

[0012] Furthermore, a filter screen is fixedly installed inside the liquid outlet hole.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The co-extruded wood-plastic composite (WPC) auxiliary splicing device of this utility model involves first placing the WPC board on top of two uprights, and then slowly placing it into a chute. Because the top of the uprights is equipped with arc-shaped guide blocks and several guide posts, it is not necessary to align the two ends of the WPC board with the chute. The arc-shaped guide blocks guide the WPC board into the chute, while the guide posts assist the WPC board in sliding. The designed guide blocks and guide posts allow the WPC board to be quickly guided into the chute, thereby improving the efficiency of WPC board installation and reducing the difficulty of installation.

[0015] 2. The co-extruded wood-plastic composite auxiliary splicing device of this utility model, when the co-extruded wood-plastic composite board enters the chute, it will squeeze the rectangular block. The rounded corners of the top of the rectangular block and the guide wheel contact the co-extruded wood-plastic composite board, thereby sliding and extending into the rectangular chute. Under the action of the spring, the sandpaper on one side of the rectangular block is always in contact with the surface of the co-extruded wood-plastic composite board. When the co-extruded wood-plastic composite board slides in the chute, the surface of the co-extruded wood-plastic composite board is polished by sandstone, thereby facilitating the subsequent rapid sliding of the co-extruded wood-plastic composite board in the chute.

[0016] 3. The co-extruded wood-plastic composite auxiliary splicing device of this utility model, when the rectangular block is compressed and slides into the rectangular groove, it moves along with the pressure plate, compressing the elastic block. This causes the lubricant inside the elastic block to enter the hollow storage frame through the guide pipe, and then flow into the chute through the liquid outlet hole in the storage frame. Spraying lubricant into the chute assists the co-extruded wood-plastic composite board in sliding within the chute. Furthermore, a filter screen is installed in the liquid outlet hole to prevent impurities from entering when the chute is not in use, thus ensuring unobstructed flow. Attached Figure Description

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figures 1 to 5 As shown in the embodiment of this utility model, a co-extruded wood-plastic composite auxiliary splicing device includes a co-extruded wood-plastic composite board 1 and a column 2. A groove 3 is formed on one side of the column 2, into which the co-extruded wood-plastic composite board 1 is inserted. Two symmetrically arranged guide blocks 4 are fixedly installed on the top of the column 2. One side of each guide block 4 is arc-shaped, and several guide posts 5 are rotatably connected to the arc-shaped surface of the guide block 4. Two symmetrically arranged rectangular slots 6 are formed inside the column 2, communicating with the groove 3. A rectangular block 8 is slidably connected to the rectangular slot 6 via a spring 7. Sandpaper 9 is fixedly installed on the side of the rectangular block 8 away from the spring 7. Rounded corners 10 are formed at the top and bottom of the rectangular block 8, and guide wheels 11 are rotatably connected to the rounded corners 10 of the rectangular block 8.

[0026] During operation, after the two uprights 2 are installed on the ground, when installing the co-extruded plastic board 1 between the two co-extruded plastic board boards 1, first place the co-extruded plastic board 1 on top of the two uprights 2, and then slowly place it into the groove 3. Because the top of the uprights 2 is equipped with arc-shaped guide blocks 4 and several guide posts 5, it is not necessary to align the two ends of the co-extruded plastic board 1 with the groove 3. The arc-shaped guide blocks 4 will guide the co-extruded plastic board 1 into the groove 3, while the guide posts 5 will assist the sliding of the co-extruded plastic board 1. The designed guide blocks 4 and guide posts 5 can quickly guide the co-extruded plastic board 1 into the groove 3, thereby improving the efficiency of installing the co-extruded plastic board 1 and reducing the difficulty of installation.

[0027] Because the actual spacing between the two uprights 2 is determined according to the specific conditions during installation, the co-extruded plastic board 1 is often cut on-site. The cut surface of the co-extruded plastic board 1 will have burrs, affecting normal sliding. Therefore, when the co-extruded plastic board 1 enters the slide groove 3, it will press against the rectangular block 8. The rounded corners 10 and guide wheels 11 of the rectangular block 8 contact the co-extruded plastic board 1, allowing it to slide and extend into the rectangular groove 6. Under the action of the spring 7, the sandpaper 9 on one side of the rectangular block 8 remains in contact with the surface of the co-extruded plastic board 1. As the co-extruded plastic board 1 slides in the slide groove 3, the surface of the co-extruded plastic board 1 is polished with sandpaper, facilitating its subsequent rapid sliding within the slide groove 3. It should be noted that the arrangement of the rectangular groove 6, rectangular block 8, spring 7, and sandpaper 9 can be determined according to the actual situation. They can be arranged on three sides of the slide groove 3 to further improve polishing efficiency.

[0028] A hollow elastic block 12 is fixedly installed inside the rectangular groove 6. Lubricant is pre-stored inside the elastic block 12. One side of the elastic block 12 is fitted with an inlet pipe connected to the interior and equipped with a one-way valve. A receiving groove 13 connected to the slide 3 is opened inside the column 2. A guide pipe 14 connected to the interior and equipped with a one-way valve is fixedly installed on one side of the elastic block 12, with one end of the guide pipe 14 located within the receiving groove 13. Four pressure plates 15 are fixedly installed on the side of the rectangular block 8 near the spring 7. The four pressure plates 15 are arranged in pairs and are arc-shaped.

[0029] Specifically, a hollow storage frame 16 is fixedly installed inside the storage tank 13. The end of the guide pipe 14 away from the elastic block 12 is connected to the inside of the storage frame 16. Several liquid outlet holes 17 are opened on the side of the storage frame 16 near the slide 3. A filter screen 18 is fixedly installed inside the liquid outlet hole 17.

[0030] During operation, when the rectangular block 8 is compressed and slides into the rectangular groove 6, it moves along with the pressure plate 15, compressing the elastic block 12. This causes the lubricant inside the elastic block 12 to enter the hollow storage frame 16 through the guide pipe 14, and then flow into the chute 3 through the liquid outlet 17 in the storage frame 16. Spraying lubricant into the chute 3 assists the co-extruded plastic board 1 in sliding within the chute 3. A filter screen 18 is installed in the liquid outlet 17 to prevent impurities from entering when the chute 17 is not in use, thus ensuring the unobstructed flow of the liquid outlet 17.

[0031] Working principle: After the two uprights 2 are installed on the ground, when installing the co-extruded plastic board 1 between the two co-extruded plastic board boards 1, first place the co-extruded plastic board 1 on top of the two uprights 2, and then slowly place it into the sliding groove 3. Since the top of the uprights 2 is equipped with an arc-shaped guide block 4 and several guide posts 5, it is not necessary to align the two ends of the co-extruded plastic board 1 with the sliding groove 3. The arc-shaped guide block 4 will guide the co-extruded plastic board 1 into the sliding groove 3, and the several guide posts 5 will assist the co-extruded plastic board 1 in sliding. Since the actual distance between the two uprights 2 is determined according to the actual situation during installation, the co-extruded plastic board 1 is often cut on-site. The cut surface of the co-extruded plastic board 1 will have burrs, which will affect normal sliding. Therefore, when the co-extruded plastic board 1 enters the chute 3, it will squeeze the rectangular block 8. The rounded corner 10 at the top of the rectangular block 8 and the guide wheel 11 will contact the co-extruded plastic board 1, thereby sliding and extending into the rectangular groove 6. Under the action of the spring 7, the sandpaper 9 on one side of the rectangular block 8 will always be in contact with the surface of the co-extruded plastic board 1. When the co-extruded plastic board 1 slides in the chute 3, the surface of the co-extruded plastic board 1 will be polished by sandpaper.

[0032] When the rectangular block 8 is compressed and slides into the rectangular groove 6, it moves along with the pressure plate 15, compressing the elastic block 12. This causes the lubricant inside the elastic block 12 to enter the hollow storage frame 16 through the guide pipe 14, and then flow into the chute 3 through the outlet hole 17 inside the storage frame 16. Spraying lubricant into the chute 3 assists the co-extruded plastic board 1 in sliding within the chute 3. A filter screen 18 is installed inside the outlet hole 17 to prevent impurities from entering when the outlet hole 17 is not in use.
