DETAILED DESCRIPTION
[0032] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.
[0033] like Figure 1-Figure 10 As shown, a composite layer color pattern forming device comprises:
[0034] A conveyor 1, the conveyor 1 having a horizontal conveying surface, the conveying surface being used to convey the extruded composite layer 5;
[0035] A graining assembly 2, the graining assembly 2 comprises a hollow graining cylinder 21 which is arranged directly above the transmission surface in a direction parallel to the width of the transmission surface, a driving unit 22 which drives the graining cylinder 21 to rotate around its own axis, and a storage shell 23 which is arranged on the inner side of the graining cylinder 21, the graining cylinder 21 is provided with a graining area along its own circumference, the graining area comprises a graining through hole 211 which forms a predetermined pattern, the storage shell 23 is a hollow shell for storing granular powder of a different color from the composite layer 5, a feeding port 231 is arranged on one side of the storage shell 23, and a discharge port 232 which extends downward to seal and fit with the inner wall of the graining cylinder 21 is arranged at the bottom;
[0036] The heating device 3 and the embossing roller 4 are arranged on the discharge side of the coating component 2 along the transmission direction of the transmission surface, the heating device 3 is adjacent to and faces the composite layer 5 on the transmission surface, the axis line of the embossing roller 4 is parallel to the axis line of the coating cylinder 21 and the embossing roller 4 rotates around its own axis line above the composite layer 5 on the transmission surface.
[0037] Specifically, the utility model is mainly installed on the discharge side of the extruder to perform color texture printing on the polymer material composite layer 5 (hereinafter referred to as "composite layer 5") extruded by the extruder to improve the colorfulness of the surface of the composite layer 5, thereby improving the appearance of the composite floor.
[0038] When the device is running, the extruded composite layer 5 is horizontally supported by the transmission surface of the conveyor 1 and the composite layer 5 is transmitted and translated. During the transmission process, the driving unit 22 in the coating component 2 runs, driving the coating cylinder 21 to rotate around its own axis, so that the coating through hole 211 in the coating area rotates around the axis of the coating cylinder 21. At the same time, powder particles in the storage shell 23 with a color different from that of the composite layer 5 are discharged from the discharge port 232 at the bottom, and fall on the top surface of the composite layer 5 through the coating through hole 211 at the bottom position of the coating cylinder 21 in the rotating state. Since the coating through hole 211 in the coating area forms a predetermined pattern, the particle powder falling on the top surface of the composite layer 5 forms a predetermined pattern.
[0039] The conveyor 1 keeps running, so that the composite layer 5 keeps in a translational state, driving the granular powder on the composite layer 5 to move, and pass through the heating device 3 together. The heating device 3 heats the granular powder and the composite layer 5, so that the powder particles and the top surface of the composite layer 5 are melted and connected to form a whole, and then pass through the embossing roller 4 to firmly bond the powder particles forming the pattern stripes to the top surface of the composite layer 5. In this way, the colorfulness of the composite layer 5 is increased, which is beneficial to improving the aesthetics of the composite floor.
[0040] In the present invention, the coating through hole 211 in the coating area forms a predetermined pattern, which is not limited to the angle shape shown in the figure, but can also be an arrow, a flower, a plant or other shapes. There are two ways to form the predetermined pattern of the coating through hole 211. First, the shape of the hole opening of the coating through hole 211 itself is the predetermined pattern. Second, the coating through hole 211 is a small hole with a hole diameter larger than the particle diameter of the granular powder and the small holes are densely distributed in the coating area (as shown in the figure). Through the above two formation methods, the granular powder at the discharge port 232 can be discharged from the coating through hole 211 at the bottom of the coating cylinder 21 and fall on the top surface of the composite layer 5. It should be noted that the coating cylinder 21 is cylindrical.
[0041] A further improvement is that the conveyor 1 includes conveying rollers 12 distributed side by side in the horizontal direction, the tops of the conveying rollers 12 are combined to form a conveying surface, the conveying rollers 12 are coaxially connected to sprockets 13, the sprockets 13 are connected to each other through chains 14, and one of the sprockets 13 is connected to a conveying motor 15 that drives it to rotate.
[0042] Specifically, Figure 4 and Figure 5 As shown, the conveyor 1 also includes a conveyor frame 11, which includes a flat plate, on which two vertical plates are integrally arranged and distributed side by side along its width direction, a conveyor roller 12 rotates around its own axis between the two vertical plates, two ends of the roller shaft of the conveyor roller 12 are respectively passed through the two vertical plates and are fixedly connected with a sprocket 13 coaxially, a conveyor motor 15 is fixed on the flat plate and is fixedly connected with one of the sprockets 13 coaxially, and two adjacent conveyor rollers 12 are arranged closely together.
[0043] After adopting the above structure, the transmission motor 15 runs, driving the sprocket 13 at one end to rotate, and driving the other sprockets 13 to rotate through the chain 14, so that the other transmission rollers 12 rotate around their own axis at the same time, and cooperate with the sprocket 13 at the other end of the transmission roller 12, so that each transmission roller 12 maintains stable transmission, thereby driving the composite layer 5 on the transmission roller 12 to move and transmit stably.
[0044] A further improvement is that at least two texture coating components 2 are provided, which are arranged on the feed side of the heating device 3 along the conveying direction of the conveying surface.
[0045] In the present embodiment, two coating components 2 are provided, and of course, other numbers may be provided. By providing more than two coating components 2, powder particles of different colors can be added to different storage shells 23 of coating components 2 to increase the colorfulness of the final composite layer 5 product. Powder particles of the same color but different color from the composite layer 5 can also be added to different storage shells 23 of coating components 2 to deepen the depth of the color of the pattern on the final composite layer 5 and highlight the display of the pattern.
[0046] A further improvement is that the discharge port 232 is in the shape of an elongated strip extending in a width direction parallel to the transmission surface, such as Fig.10 As shown, this helps the granular powder in the storage shell 23 to be evenly discharged from the discharge port 232 and fall onto the composite layer 5 through the coating through hole 211 at the bottom of the coating cylinder 21.
[0047] A further improvement is that the coated through holes 211 are densely distributed in the coated area, which helps the granular powder discharged from the discharge port 232 to be discharged evenly and orderly from the coated through holes 211. Compared with the coated through holes 211 forming a single predetermined pattern, the discharge speed of the granular powder can be reduced, avoiding the granular powder from being discharged too quickly, resulting in excessive use of granular powder and the need to frequently add granular powder to the storage shell 23.
[0048] A further improvement is that the texturing cylinder 21 is provided with at least two texturing areas distributed along its circumference.
[0049] In the present invention, each texture drum 21 has three texture areas equally spaced along its circumference, and the three texture areas have the same shape and structure. Thus, each time the texture drum 21 rotates one circle, three patterns of the same shape and size can be formed on the composite layer 5, which is beneficial to reducing the number of texture components 2 and avoiding too many texture components 2, which may cause the temperature of the composite layer 5 to be too low before passing through the heating device 3, thereby affecting the melting connection effect between the composite layer 5 and the granular powder.
[0050] Of course, the coating areas on the coating cylinder 21 can also have other numbers, and the coating areas can also adopt different shapes and sizes. In this way, after the coating cylinder 21 rotates, patterns of different shapes and sizes can be formed on the composite layer 5 to increase the diversity of the top surface of the composite layer 5 and further enhance the aesthetics of the composite floor.
[0051] A further improvement is that the driving unit 22 includes a driving motor 221, a driving wheel 222, a synchronous belt 223 and a driven wheel 224. The driving motor 221 is arranged on the conveyor 1 and the output end is connected to the driving wheel 222 coaxially. The driving wheel 222 is connected to the driven wheel 224 through the synchronous belt 223, and the driven wheel 224 is fixedly connected to the coating cylinder 21 coaxially.
[0052] Specifically, Figure 1-Figure 3 , Figure 6-Figure 9 As shown, driven wheels 224 are fixed at both ends of the coating cylinder 21, and driving wheels 222 are provided. The driving wheels 222 are connected to the driven wheels 224 through a synchronous belt 223. The driving wheels 222 at both ends are fixed with concentric shafts 26. The driving motor 221 is fixed on the transmission frame 11 and is connected to the concentric shaft 26.
[0053] After adopting the above structure, the driving motor 221 is used to drive the coaxial shaft 26 to rotate, so that the driving wheels 222 at both ends of the coating cylinder 21 rotate synchronously. At the same time, the driving wheel 222 drives the driven wheel 224 to rotate through the synchronous belt 223, so that the coating cylinder 21 rotates.
[0054] A further improvement is that both ends of the storage shell 23 are provided with a feed port 231, the feed port 231 is connected to a feed pipe 233, the feed pipe 233 extends along the axial direction of the coating cylinder 21 to the outside of the coating cylinder 21 and is fixed on the conveyor 1; the feed pipe 233 coaxially passes through the driven wheel 224; both ends of the coating cylinder 21 are fixed with an annular cylinder cover 24, and the cylinder cover 24 is coaxially provided with a ring 25, and the ring 25 is fitted between the circumferential inner wall of the driven wheel 224 and the circumferential outer edge of the feed pipe 233.
[0055] Specifically, the feed pipe 233 is fixed on the transmission frame 11 along the width direction parallel to the transmission surface and passes through the driven wheel 224, which helps to fix the position of the storage shell 23; the annular cylinder cover 24 has its circumferential outer edge fixedly connected to the circumferential inner wall at the end position of the coating cylinder 21, and the cylinder cover 24 is coaxially fixedly connected with a ring 25, and the circumferential outer edge and circumferential inner wall of the ring 25 are respectively fitted with the circumferential inner wall of the driven wheel 224 and the circumferential outer edge of the feed pipe 233, which helps to ensure the stable rotation of the cylinder cover 24 and the coating cylinder 21; the feed pipes 233 at both ends of the storage shell 23 extend outward, which is convenient for replenishing granular powder of a different color from the composite layer 5 into the storage shell 23.
[0056] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
