Description

Technical Field

[0001] This utility model relates to the field of flooring technology, and more specifically, to a device for optimizing the uniformity of co-extruded solid layers in flooring. Background Technology

[0002] Co-extruded flooring is highly praised by customers for its lightweight, high strength, comfortable feel, and easy installation. This product is 25% lighter than solid flooring of the same thickness, and its toughness is superior. It also requires fewer production steps and has lower costs than foamed flooring, and it does not experience interlayer separation. Its strength is also superior to foamed flooring. However, co-extruded flooring requires specific production technology, unlike traditional solid or foamed flooring which have lower manufacturing barriers. Therefore, it is relatively rare in the market. One of the most challenging issues is ensuring uniform thickness of the solid layer in co-extruded flooring. This leads to significant differences in the overall thickness and density of the co-extruded flooring, directly affecting subsequent processing and overall stability, ultimately impacting the quality of the finished product.

[0003] The main reason for the uneven thickness of the solid layer is that, in actual production, co-extruded flooring is extruded by two extruders, each responsible for extruding two layers of different materials. The foam layer is extruded by the main extruder, while the solid layer is extruded by the auxiliary extruder. A distributor is installed outside the flooring mold. The two layers of material enter the mold after being pressurized by the distributor. The foam layer material can directly enter the distributor after being extruded by the main extruder, while the solid layer material, due to its special material properties, needs to pass through a transfer station and two transition sleeves before reaching the distributor. The path is relatively long. Because the solid layer material passes through the channels inside the transition sleeves, it is cylindrical when it reaches the distributor. After entering the distributor, the cylindrical material is not easy to disperse, resulting in poor flowability and pressure distribution. This leads to uneven distribution and different flow rates between the upper and lower layers of material when entering the distributor, resulting in uneven thickness of the solid layer in the final finished flooring, which affects the quality of the product. Utility Model Content

[0004] In view of this, the present invention provides an optimized device that can effectively improve the uniformity of thickness of the solid layer of co-extruded flooring.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A device for optimizing the uniformity of a co-extruded solid floor layer includes a distribution plate and two distribution cones. The two distribution cones are symmetrically arranged on both sides of the distribution plate, with the tips of the distribution cones facing away from the distribution plate. The distribution plate has a distribution hole, and a plurality of cutters are provided in the distribution hole. The plurality of cutters are arranged at the same included angle along the radial direction of the distribution hole, and one end of the cutter is connected to the sidewall of the distribution hole.

[0007] The co-extruded flooring consists of two extruders that extrude two different materials: a foamed layer and a solid layer. The foamed layer goes directly into the distributor, while the solid layer material passes through a transition sleeve before reaching the distributor. The uniformity optimization device of this application is installed in the transition sleeve. When the solid layer material is extruded into the transition sleeve, it is first diverted by a diversion cone on one side of the diversion plate, changing from a cylindrical shape to an annular shape. Then, it passes through the diversion holes on the diversion plate, where multiple cutters cut the material into multiple equally sized fan-shaped structures. The fan-shaped materials then pass through a diversion cone on the other side of the diversion plate and enter the distributor. The diversion cone at the rear section guides the flow of the cut fan-shaped materials, thus preventing the cut materials from quickly sticking together again.

[0008] In summary, this application, through the setting of a diversion cone and a diversion plate, cuts the originally cylindrical material into multiple fan-shaped materials, which can significantly improve the material's flowability and dispersibility. The material after cutting is superior to the original cylindrical material in terms of both flowability and pressure distribution. The solid layer of the finished floor obtained after processing by this device has significantly improved thickness uniformity, thus significantly improving the quality of the finished floor.

[0009] Alternatively, in one embodiment, the flow divider cone is conical in shape, and the diameter of the flow divider cone is smaller than the diameter of the flow divider orifice.

[0010] In the above technical solution, the cylindrical material itself is not easy to disperse. The conical structure can first break the round material into pieces, which is convenient for subsequent cutting. The diameter of the diversion cone is smaller than that of the diversion hole, so that the material can pass through the diversion hole after being guided by the diversion cone.

[0011] Optionally, in one embodiment, a mounting post is provided inside the diversion hole, the mounting post is located at the center of the diversion hole, one end of the cutter is connected to the outer periphery of the mounting post, and the other end is connected to the side wall of the diversion hole.

[0012] In the above technical solution, the cutter is located between the mounting post and the hole wall of the diversion hole, and its two ends are fixedly connected to the mounting post and the hole wall of the diversion hole, respectively.

[0013] Optionally, in one embodiment, the mounting post is provided with a mounting hole that extends axially, and the end of the diverter cone is provided with a mounting protrusion that mates with the mounting hole.

[0014] In the above technical solution, the mounting column is used to provide a mounting position for the flow divider cone, and the mounting column is provided with an axially penetrating mounting hole for the flow divider cones on both sides to be installed.

[0015] Optionally, in one embodiment, the mounting protrusion and the mounting hole are provided with matching threads.

[0016] In the above technical solution, threads are provided on the sidewalls of the mounting protrusion and the mounting hole, so that the flow divider cone and the flow divider plate can be detachably connected by the threads, which facilitates disassembly and assembly and improves practicality.

[0017] Compared with the prior art, the beneficial effects of this application are as follows:

[0018] This application, through the setting of a diversion cone and a diversion plate, cuts the originally cylindrical material into multiple fan-shaped structures before the material reaches the mold distributor, effectively enhancing the dispersion and flowability of the material. This improves the problem of uneven thickness of the solid layer of the finished floor caused by the poor dispersion and flowability of solid cylindrical material, effectively improving the thickness uniformity of the finished floor. The diversion cone is set on both sides of the diversion plate, which can prevent the material cut by the cutter inside the diversion plate from re-merging together, thereby effectively improving the reliability of the device.

[0019] This application has a simple structure, is easy to install, and is easy to manufacture and process, with low cost, which helps to put it into large-scale production. Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0032] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0033] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0034] The technical solutions in this application will now be described with reference to the accompanying drawings. Example 1

[0035] Please refer to Figures 1 to 7 This embodiment provides a device for optimizing the uniformity of solid layers in co-extruded flooring, applied to the production of co-extruded flooring. It includes a distribution plate 1 and two distribution cones 2. The two distribution cones 2 are symmetrically arranged on both sides of the distribution plate 1. The tip of the distribution cone 2 faces away from the distribution plate 1. The distribution plate 1 is provided with a distribution hole 11. A mounting post 13 is provided in the distribution hole 11. A plurality of cutters 12 are provided between the mounting post 13 and the side wall of the distribution hole 11. The plurality of cutters 12 are all arranged along the radial direction of the distribution hole 11 and distributed in the distribution hole 11 at the same included angle. The two ends of the cutters 12 are respectively connected to the outer periphery of the mounting post 13 and the side wall of the distribution hole 11.

[0036] It should be noted that this device is installed inside the transition sleeve 3. In this embodiment, there are two transition sleeves 3. The transition sleeve 3 on the left is embedded in the other transition sleeve 3. Both transition sleeves 3 are provided with channels for material to pass through. This uniformity optimization device is installed at the junction of the channels inside the two transition sleeves 3. The transfer station is located on the right side of the two transition sleeves 3, and the distributor is located on the left side of the two transition sleeves 3.

[0037] Preferably, in this embodiment, there are four cutters 12, all of which are arranged along the radial direction of the diversion hole 11, with the included angle between adjacent cutters 12 being 90°, forming an overall cross-shaped structure.

[0038] In actual work, such as Figure 1 As shown, the material enters through the right side of the internal channel of the transition sleeve 3 via the transfer station. The material is first guided by the diversion cone 2 on the right side of the diversion plate 1, changing from a cylindrical shape to a ring shape. Then, it passes through the diversion hole 11, where the cutter 12 cuts the material into four equal-sized fan-shaped structures. After that, it is guided by the diversion cone 2 on the left side of the diversion plate 1, recombined, and then discharged from the left side of the internal channel of the transition sleeve 3 into the distributor. The diversion cone 2 on the left side is used to guide the cut fan-shaped material, thereby preventing the cut material from quickly sticking together again and providing a buffer section for the material that has just been cut.

[0039] It is understood that the circular and fan-shaped shapes mentioned in this embodiment refer to the shape of the material's cross-section.

[0040] In summary, this device, through the diversion cone 2 and diversion plate 1, cuts the originally cylindrical material into multiple fan-shaped materials, which can significantly improve the flowability and dispersibility of the material. The material after cutting is superior to the original cylindrical material in terms of both flowability and pressure distribution. In terms of the product, the thickness uniformity of the solid floor layer obtained after processing by this device is significantly improved.

[0041] Preferably, the diverting cone 2 is conical in shape. Since the cylindrical material is not easy to disperse, the conical structure can initially break the round material through its tip to form a ring, which is convenient for the subsequent cutting blade 12 to cut and reduce the pressure on the cutting blade 12 during cutting. In addition, the surface of the conical structure is arc-shaped, which also reduces the resistance to the material and facilitates the extrusion of the material.

[0042] Preferably, the diameter of the diversion cone 2 is equal to the diameter of the mounting post 13, so that the diversion cone 2 will not obstruct the cutter 12, thus ensuring full contact between the cutter 12 and the material.

[0043] Please refer to Figures 2 to 7In this embodiment, the mounting column 13 is provided with a mounting hole 131 that runs through the axial direction, and the end of the diverting cone 2 is provided with a mounting protrusion 21 that cooperates with the mounting hole 131. The diverting cone 2 is mounted on the mounting column 13 through the mounting protrusion 21, so that the diverting cone 2 and the diverting plate 1 form an integral whole, improving stability. Thus, when the material is squeezed through, the diverting cone 2 will not deviate due to excessive force, improving the reliability of the device.

[0044] Preferably, the sidewalls of the mounting protrusion 21 and the mounting hole 131 are provided with threads, which enable the flow divider cone 2 and the flow divider plate 1 to form a detachable connection, ensuring a stable connection while facilitating disassembly and assembly and improving practicality. Example 2

[0045] This embodiment is basically the same as Embodiment 1 in structure and principle. The difference is that the cutter 12 in this embodiment is provided with 2, 3 or more. When there are 2 cutters 12, the 2 cutters 12 are symmetrically distributed on both sides of the mounting post 13. When there are 3 or more cutters 12, the included angle between adjacent cutters 12 is equal. The included angle is 360° divided by the actual number of cutters 12.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
