Description

Technical Field

[0001] The invention relates to the technical field of wallboard production equipment, in particular to an extruder for wallboards. Background Art

[0002] With the improvement of living standards, people's requirements for the quality of interior decoration materials are gradually increasing, and interior decoration materials are also constantly being updated. Bamboo fiber integrated wall panels are made of PVC, calcium powder, bamboo fiber and other raw materials that are extruded to form a wood-plastic substrate, and then bonded to the surface of the substrate with PUR hot melt adhesive and PVC film, PP film or wall cloth. Bamboo fiber integrated wall panels have been favored by the majority of owners as soon as they were launched on the market due to their advantages such as fast decoration speed and environmental protection.

[0003] When adding powder to the existing extruder, a large amount of powder cannot be directly put into the feed barrel on the extruder, which is easy to cause blockage. If it is put in in an assembly line, a small amount of material needs to be put into the feed barrel, which also has the chance of causing blockage. In addition, other equipment needs to be operated synchronously with the extruder, and it needs to be inspected frequently, and the amount of powder entering the extruder cannot be controlled.

[0004] In addition, it is very difficult to change the existing extruders to produce wall panels of other structures or specifications, which greatly affects the production efficiency. Summary of the invention

[0005] In view of the above shortcomings, the present invention provides an extruder for wall panels to solve the problems of clogging of the feed barrel on the extruder, inability to control the feed amount, and difficulty in changing to produce wall panels of other structures or specifications.

[0006] In order to achieve the above object, the present invention adopts the following technical scheme:

[0007] An extruder for wall panels, comprising:

[0008] A driving section, wherein the driving section comprises a first motor, a driving housing and a transmission mechanism, wherein the transmission mechanism is disposed in the driving housing, and an input end of the transmission mechanism is connected to an output shaft of the first motor;

[0009] A compression section, wherein the compression section comprises a conveying mechanism and a conveying pipe, wherein the conveying mechanism is arranged in the conveying pipe, wherein one end of the conveying pipe is connected to the driving housing, wherein the input end of the conveying mechanism is connected to the output end of the transmission mechanism, wherein a feed port is arranged at the end of the conveying pipe connected to the driving housing, wherein a feed barrel is arranged on the feed port, wherein a loosening mechanism for preventing the feed port from being blocked is arranged in the feed barrel;

[0010] The plate-discharging section comprises a molding frame and a molding head. The inlet end of the molding frame is connected to the outlet end of the conveying pipe, and the molding head is fixedly connected to the outlet end of the molding frame.

[0011] Through the above scheme, the first motor provides the driving force required for the entire extrusion process. The conveying mechanism in the compression section is responsible for conveying the material from the feed port to the discharge end. The loosening mechanism in the feed barrel can effectively prevent powder blockage. The molding frame and the molding head constitute the board discharge section to determine the shape and structure of the product. The inlet of the molding frame is directly connected to the outlet of the conveying pipe, and the outlet is fixed with a molding head, which can ensure that the material can be quickly shaped after heating and compression to form a high-quality product. In particular, the molding head can be quickly replaced as needed to adapt to the production of wall panels of different specifications or types, greatly improving the flexibility and conversion efficiency of the production line.

[0012] Furthermore, the transmission mechanism includes a worm, a worm wheel and a first connecting rod, the worm and the worm wheel are both rotatably connected in the driving housing, the worm is meshingly connected to the worm wheel, a first connecting rod is fixedly connected to the middle of the worm wheel, the first connecting rod is connected to the worm wheel at one end and a first connecting plate is provided on the opposite end, and one end of the worm passes through the driving housing to the outside and is fixedly connected to the output shaft of the first motor.

[0013] Through the above further solution, the first motor drives the worm to rotate, the worm drives the worm wheel to rotate, and the worm wheel drives the first connecting rod to rotate, so that the first connecting disk on the first connecting rod rotates.

[0014] Furthermore, the conveying mechanism includes a transmission rod and a second connecting rod, the transmission rod is located in the conveying tube, one end of the second connecting rod is provided with a second connecting disk, the second connecting disk is fixedly connected to the first connecting disk, one end of the transmission rod passes through one end of the conveying tube and is fixedly connected end to end with the second connecting rod provided with a second connecting disk, and the other end is flush with the discharge end of the conveying tube, and a spiral rib is rotatably wrapped around the transmission rod and abuts against the inner wall of the conveying tube.

[0015] Through the above-mentioned further scheme, the first connecting disk drives the second connecting disk to rotate, the second connecting disk drives the second connecting rod to rotate, and the second connecting rod drives the transmission rod to rotate, so that the spiral ribs on the transmission rod can effectively push the material forward in the conveying pipe, reducing the risk of blockage, and the spiral ribs fit tightly to the inner wall of the conveying pipe, which can ensure the uniform distribution of materials during the conveying process and avoid the occurrence of local accumulation or voids.

[0016] Furthermore, the diameter of the transmission rod increases gradually from one end to the other end, and the end of the transmission rod with a larger diameter is located at the discharge end of the conveying pipe.

[0017] Through the above further scheme, as the diameter of the transmission rod gradually increases from the feed end to the discharge end, the pressure it exerts on the material also increases, which can provide a stronger compression effect at the discharge end, help to remove the air in the material and make the materials more tightly combined, thereby improving the strength and durability of the product, so that the material can be better pre-treated before entering the discharge end, which is convenient for subsequent plasticity.

[0018] Furthermore, the loosening mechanism includes a second motor, a rotating rod, a loosening piece and a conveying head. A cover plate is provided on the feed barrel, a feed port is provided on the cover plate, the second motor is fixedly mounted on the cover plate, an output shaft of the second motor passes through the cover plate and is fixedly connected to one end of the rotating rod, the other end of the rotating rod is fixedly connected to the conveying head, a loosening piece is fixedly connected to the rotating rod, and the conveying head and the rotating rod are connected end to end and are located in the feed port.

[0019] Through the above further solution, the loosening member rotates with the rotating rod to continuously stir the material, thereby effectively avoiding blockage at the place where the material is agglomerated due to humidity or other factors in the feeding barrel.

[0020] Furthermore, a spiral disk is spirally wound on the conveying head, and one end of the conveying head located in the feed inlet is conical.

[0021] Through the above further scheme, the spiral disk not only helps the material to move forward and prevents the feed port from being blocked, but also can pre-compress the material to a certain extent, which is especially important for materials that require higher density in subsequent processing. It can also ensure the stability and consistency of the material during the entire conveying process.

[0022] Furthermore, the loose member is in a double ring shape, the inner ring of the loose member is fixedly connected to the rotating rod, and the outer ring of the loose member is provided with a spiral ring.

[0023] Through the above further scheme, the double-ring loose parts increase the contact area with the material. Compared with a single-ring or linear design, they can more effectively stir and disperse the material, help break up the lumps in the material, ensure that the material is more evenly distributed, and further stir the material more evenly.

[0024] Furthermore, a molding cavity is provided in the molding frame, the molding cavity inlet end is circular, and its diameter is the same as the diameter of the conveying pipe outlet end, the molding cavity outlet end is rectangular, the height of the molding cavity from the inlet end to the outlet end gradually decreases, and the width of the molding cavity from the inlet end to the outlet end gradually increases.

[0025] Through the above further scheme, the change from circular to rectangular helps the material to quickly adjust its flow direction and speed after entering the molding cavity, ensuring that the material is evenly distributed over the entire cross section, which can reduce product defects caused by uneven material flow rate, such as bubbles, voids or inconsistent density. The design of gradually decreasing height and gradually increasing width allows the material to transition smoothly during the gradual change, avoiding turbulence or shear stress concentration that may be caused by sharp angle changes, thereby ensuring the stability of material flow. As the material changes shape when passing through the molding cavity, the thickness of the material layer will also change accordingly, which helps to achieve a more uniform cooling process. Uniform cooling is crucial to preventing common problems such as product warping and uneven shrinkage, especially for large or complex structured products.

[0026] Furthermore, a molding cavity connected to the discharge end of the molding cavity is provided in the middle of the molding head, the shape of the molding cavity feed end is the same as the shape of the molding cavity discharge end, and the molding cavity discharge end is used for extruding and molding wall panels.

[0027] Through the above further scheme, since the shape of the feeding end of the molding cavity is the same as the shape of the discharging end of the molding cavity, a smooth transition of the material from the molding cavity to the molding cavity is ensured, reducing any obstacles or mutations that may affect the flow of the material, and helping to maintain the consistency of the material flow, thereby improving the dimensional accuracy and surface quality of the final product. By replacing different molding heads, wall panels of corresponding specifications and shapes can be produced.

[0028] Compared with the prior art, the present invention has the following beneficial effects: the loosening mechanism in the feed barrel can continuously stir the material, effectively avoiding blockage at the place where the material is agglomerated due to humidity or other factors in the feed barrel; the molding frame and the molding head constitute the board outlet section, determining the shape and structure of the product; the inlet of the molding frame is directly connected to the outlet of the conveying pipe, and the outlet is fixed with a molding head, which can ensure that the material can be quickly shaped after heating and compression to form a high-quality product; in particular, the molding head can be quickly replaced as needed to adapt to the production of wall panels of different specifications or types, greatly improving the flexibility and conversion efficiency of the production line.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0038] Example:

[0039] Reference Figure 1-Figure 3As shown, an extruder for wall panels includes a driving housing 2, in which a worm 31 and a worm wheel 32 are rotatably connected, the worm 31 is meshingly connected to the worm wheel 32, a first connecting rod 33 is fixedly connected to the middle of the worm wheel 32, the first connecting rod 33 is connected to the worm wheel 32 at one end and a first connecting plate 331 is provided on the opposite end, one end of the worm 31 passes through the driving housing 2 to the outside and is fixedly connected to the output shaft of the first motor 1, the worm 31 cooperates with the worm wheel 32 to form a self-locking structure, and can avoid large thread wear when used for a long time, thereby affecting the quality of wall panel production.

[0040] Reference Figure 1-Figure 2 As shown, one end of the driving shell 2 is connected to the conveying pipe 5, and a transmission rod 41 is provided in the conveying pipe 5. One end of the transmission rod 41 passes through one end of the conveying pipe 5 to the driving shell 2 and is fixedly connected to a second connecting rod 42. The second connecting rod 42 and the transmission rod 41 are connected with a second connecting disk 421 on the ends thereof. The second connecting disk 421 is fixedly connected to the first connecting disk 331. The other end of the transmission rod 41 is flush with the discharge end of the conveying pipe 5. A spiral rib 411 is rotatably wound around the transmission rod 41 and is close to the inner wall of the conveying pipe 5. The powder can be transported by the spiral rib 411.

[0041] Among them, the diameter of the transmission rod 41 gradually increases from one end to the other end, and the end with a larger diameter of the transmission rod 41 is located at the discharge end of the conveying pipe 5. In the process of the spiral fins 411 conveying the powder to the discharge end of the conveying pipe 5, the powder is gradually squeezed to increase the density of the powder and make it more compact. If there is air in the powder, it can be discharged during the conveying process to prevent the formation of cavities or bubbles.

[0042] It should be noted that a heating device is provided on the outside of the conveying pipe 5, which is a prior art and will not be described here.

[0043] Reference Figure 1 , Figure 2 and Figure 4As shown, a feed port 51 is provided at the connection end of the conveying pipe 5 and the driving housing 2, a feed barrel 511 is provided on the feed port 51, a cover plate 512 is provided on the feed barrel 511, a feed port 513 is provided on the cover plate 512, and a second motor 61 is fixedly installed in the middle of the cover plate 512, the output shaft of the second motor 61 passes through the cover plate 512 and is fixedly connected to a rotating rod 62, a conveying head 64 is fixedly connected to the bottom end of the rotating rod 62, a loosening member 63 is fixedly connected to the rotating rod 62, and the conveying head 64 and the rotating rod 62 are connected end to end at the feed port 51. The loosening member 63 can break up the powder before it enters the conveying pipe 5 to avoid agglomeration, and can also continuously stir the powder to increase the uniformity between the powders of various substances in the powder. The conveying head 64 is fixedly connected to the bottom end of the rotating rod 62, and a spiral disk 641 is spirally wound on the conveying head 64. When the rotating rod 62 rotates, the conveying head 64 is located in the feed port 51, helping to guide the powder to enter the conveying pipe 5 smoothly, avoiding the powder from blocking the feed port 51, and can adjust the conveying amount of the powder by adjusting the spiral disk 641 and the rotation of the conveying head 64.

[0044] Among them, one end of the conveying head 64 located in the feed port 51 is conical. The conical structure can naturally disperse the powder when the rotating rod 62 rotates, and the conical structure avoids a small space at the material port, thereby avoiding blockage of the material at the feed port 51.

[0045] Among them, the loosening member 63 is a double ring, the inner ring of the loosening member 63 is fixedly connected to the rotating rod 62, and the outer ring of the loosening member 63 is provided with a spiral ring 631. The spiral ring 631 increases the surface area in contact with the powder and stirs the powder more effectively, which not only prevents the powder from agglomerating, but also increases the uniformity between the powders of various substances in the powder.

[0046] Reference Figure 1 and Figure 2 As shown, the discharge end of the conveying pipe 5 is connected to a molding frame 7, and a molding cavity 71 is arranged in the molding frame 7. The feeding end of the molding cavity 71 is circular, and its diameter is the same as the diameter of the discharge end of the conveying pipe 5. The discharge end of the molding cavity 71 is rectangular, and the height of the molding cavity 71 gradually decreases from the feeding end to the discharge end, and the width of the molding cavity 71 gradually increases from the feeding end to the discharge end. The discharge end of the conveying pipe 5 is directly connected to the molding frame 7 to ensure that the powder can seamlessly enter the molding cavity 71 from the conveying pipe 5. The feeding end is designed to be circular, and its diameter is the same as the diameter of the discharge end of the conveying pipe 5 to ensure a smooth transition between the two and reduce the risk of material loss or blockage at the junction. The powder gradually forms a rectangle by gradually decreasing the height and increasing the width, and is thus extruded from the discharge end to form a rough wall panel.

[0047] Reference Figure 1 and Figure 2As shown, the discharge end of the molding frame 7 is fixedly connected to the molding head 8, and a molding cavity 81 connected to the discharge end of the molding cavity 71 is provided in the middle of the molding head 8. The shape of the feeding end of the molding cavity 81 is the same as the shape of the discharge end of the molding cavity 71, and a structure for extruding a wall panel is provided on the discharge end of the molding cavity 81.
