Description

Technical Field

[0001] The invention relates to the technical field of plastic processing, in particular to a production method of a plastic rattan-like material. Background Art

[0002] As we all know, natural rattan is widely used to make various furniture due to its unique natural tension and moderate elasticity, especially in outdoor places such as parks, amusement parks and resorts. Chairs, tables and swings made of rattan are deeply loved by people. This love comes not only from the functionality of furniture, but also because rattan brings people a feeling of close contact with nature. The characteristics of green, healthy and close to nature make rattan furniture particularly popular.

[0003] However, as this demand increases, the amount of natural rattan harvested is also increasing, causing serious damage to the natural environment. In order to solve this problem, artificial rattan has appeared on the market. However, most artificial rattans are solid or flat, with a uniform cross-sectional area, which makes the products look monotonous and dull, lacking three-dimensionality, change and naturalness, and at the same time, the material utilization rate is low. Summary of the invention

[0004] The purpose of the present invention is to overcome the shortcomings of the existing technology and provide a method for producing plastic rattan-like materials with a simple structure and easy use. The method can produce plastic rattan-like materials with different cross-sectional areas and shapes by improving the production process, so that the products produced not only have a more three-dimensional, varied and natural appearance, but also have significantly improved material utilization and production efficiency.

[0005] The object of the present invention is achieved in the following manner: a production method of a plastic rattan-like material, characterized in that it comprises the following steps: S1: a plastic extruder is provided, an extrusion die is installed on the discharge end of the plastic extruder, and a plurality of discharge holes are provided on the extrusion die; S2: Several discharge holes simultaneously eject several fluid rubber strips, which naturally fall into the cooling water tank below; S3: When the fluid rubber strip naturally falls into the cooling water tank, it naturally coils into a ring under the action of its own weight.

[0006] S4: The fluid rubber strip that falls into the cooling water tank is moved in the cooling water tank to be immersed and cooled under the traction of the traction device.

[0007] S5: The cooled and shaped rubber strip enters the winding machine for collection to form a finished product.

[0008] Steps S3A and S3B are provided between steps S3 and S4: S3A: A transverse extrusion shaping groove with a gradually reduced width is provided in the water tank. The coiled rubber strip enters the transverse extrusion shaping groove under the action of traction force, and a number of coiled rubber strips are transversely extruded and shaped to reduce their width; S3B: The transversely extruded rubber strip enters between the upper and lower pressure rollers and is vertically extruded.

[0009] The transverse extrusion shaping groove is submerged in the cooling water tank and is arranged in a V-shape.

[0010] The transverse extrusion shaping groove is submerged in the cooling water groove and is arranged in a Y shape.

[0011] The upper and lower pressing rollers are submerged in a cooling water tank and are driven to rotate by a motor.

[0012] The pulling speed of the pulling device is lower than the linear speed of the fluid rubber strip ejected from the discharge hole.

[0013] The plurality of discharge holes are located at the same horizontal height and on the same plane.

[0014] The plurality of discharge holes are arranged in two rows, the upper discharge holes correspond to the lower discharge holes one by one, and the upper discharge holes on the same vertical row protrude from the end surface of the lower discharge holes, so that the fluid rubber strips extruded from the two discharge holes fall into the cooling water tank in a front-to-back offset manner.

[0015] In the above-mentioned S2, the fluid rubber strip naturally falls into the cooling water tank below it, and the circle formed by the rear-stage discharge is partially overlapped with the circle formed by the front-stage discharge, or the left and right parts of the circles formed by two adjacent fluid rubber strips are overlapped.

[0016] The beneficial effects of the present invention are: 1. Simple structure, low production cost and improved market competitiveness.

[0017] This method can make the fluid rubber strip naturally coil into a circle during the production process by coordinating the discharge speed of the extrusion die with the traction speed of the traction device (that is, the discharge line speed is higher than the traction speed), so that the produced rattan can imitate the spiral shape of natural rattan.

[0018] Through horizontal and vertical extrusion shaping process, the surface of rattan can form a natural mesh effect. This mesh effect not only increases the three-dimensional sense of rattan, but also makes the manufactured products more beautiful and has higher added value.

[0019] 4. Traditional simulated rattan is mostly solid or flat, but the present invention uses a specific extrusion shaping process to effectively control the cross-sectional area and shape of the rattan, reducing material waste and improving material utilization. Compared with solid rattan, the rattan of the present invention uses less material and has lower cost while ensuring strength and aesthetics.

[0020] 5. Since the rattan produced by the present invention has a natural mesh effect, the products produced are more three-dimensional and have a stronger sense of hierarchy in appearance, and are no longer monotonous flat effects. The enhanced three-dimensional effect makes the furniture and decorations more visually attractive and more competitive in the market. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The present invention is further described in detail below with reference to the accompanying drawings. A method for producing a plastic rattan-like material, characterized in that it comprises the following steps: S1: A plastic extruder 1 is provided, and an extrusion die 2 is installed on the discharge end thereof, and a plurality of discharge holes are provided on the extrusion die 2; S2: a plurality of discharge holes spray out a plurality of fluid rubber strips 3, and the fluid rubber strips 3 naturally fall into the cooling water tank 4 below; S3: When the fluid rubber strip 3 naturally falls into the cooling water tank 4, it naturally coils into a ring shape under the action of its own weight; S4: The fluid rubber strip 3 dropped into the cooling water tank 4 is moved in the cooling water tank 4 to be immersed and cooled under the traction of the traction device.

[0025] S5: The cooled and shaped rubber strip enters the winding machine 7 for collection to form a finished product.

[0026] In one embodiment, steps S3A and S3B are provided between steps S3 and S4: S3A: A transverse extrusion shaping groove 5 with a gradually decreasing width is provided in the water tank. The coiled rubber strip enters the transverse extrusion shaping groove 5 under the action of traction force, and a number of coiled rubber strips are transversely extruded and shaped to reduce their width; S3B: The rubber strip formed by transverse extrusion enters between the upper and lower pressing rollers 6 and is vertically extruded.

[0027] The transverse extrusion shaping groove 5 is submerged in the cooling water groove 4 and is arranged in a V-shape.

[0028] The transverse extrusion shaping groove 5 is submerged in the cooling water groove 4 and is arranged in a Y shape.

[0029] The upper and lower pressing rollers 6 are submerged in the cooling water tank 4 and are driven to rotate by a motor.

[0030] The pulling speed of the pulling device is lower than the linear speed of the fluid rubber strip 3 ejected from the discharge hole.

[0031] The plurality of discharge holes are located at the same horizontal height and on the same plane.

[0032] The plurality of discharge holes are arranged in two rows, the upper discharge holes correspond to the lower discharge holes one by one, and the upper discharge holes in the same vertical row protrude from the end surface of the lower discharge holes, so that the fluid rubber strips 3 squeezed out of the two discharge holes fall into the cooling water tank 4 in a front-to-back offset manner.

[0033] In one embodiment, the transverse extrusion shaping groove 5 is submerged in the cooling water groove 4 and is arranged in a V-shape.

[0034] In one embodiment, the transverse extrusion shaping groove 5 is submerged in the cooling water groove 4 and is arranged in a Y shape.

[0035] The fluid rubber strip 3 naturally falls into the cooling water tank 4 below it, and the circle formed by the rear discharge is partially overlapped with the circle formed by the front discharge, or the left and right parts of the circle formed by two adjacent fluid rubber strips 3 are overlapped.

[0036] Compared with the traditional technology, in this method, the fluid rubber strips are naturally coiled in the cooling water tank to form a ring structure, so that the rattan produced has a natural spiral curling shape, and can also be directly generated with a mesh effect rattan (due to different materials, the stacking method is adjusted accordingly) through the subsequent extrusion shaping process, or through the mutual coordination of the extrusion die discharge speed and the traction speed of the traction device (that is, the speed between the two speeds, so that the fluid rubber strips are naturally coiled in the cooling water tank and overlap each other). This naturally formed mesh makes the rattan more three-dimensional and layered visually.

[0037] In addition, the cooling process in the cooling water tank ensures the shaping process of the rubber strip at different temperature stages. Depending on the material of the product, a cooling step outside the water tank can be added to ensure that the final product has excellent dimensional stability and physical properties.

[0038] Furthermore: through the horizontal and vertical extrusion shaping process, the shape and size of the rubber strip are precisely controlled, while the mesh effect and structural strength of the rattan are enhanced.

[0039] In addition, most traditional simulated rattans are solid or flat in shape, while the present invention uses a specific extrusion shaping process to effectively control the cross-sectional area and shape of the rattan, reducing material waste and improving material utilization. Compared with solid rattan, the rattan of the present invention uses less material and has lower cost while ensuring strength and aesthetics.

[0040] Furthermore, since the rattan produced by the present invention has a natural mesh effect, the products produced are more three-dimensional and have a stronger sense of hierarchy in appearance, and are no longer monotonous flat effects. This enhanced three-dimensional effect makes the production of furniture and decorations more visually attractive and market competitive. In addition, the traditional rattan production process requires the use of a variety of rattans of different shapes and colors to mix and produce, which is complicated to operate and easy to knot, and has low production efficiency. The present invention optimizes the production process so that rattan with a mesh effect can be produced in a single process, eliminating the step of mixing and producing a variety of rattans, simplifying the process flow, and greatly improving production efficiency.

[0041] In addition, since the method of the present invention can directly produce rattan with a mesh effect, it reduces material waste and complex operations in the production process, and reduces production costs. At the same time, the improvement of material utilization rate further reduces the consumption of raw materials, so that the overall production cost is significantly reduced, which has significant technical advantages and broad application prospects.

[0042] Obviously, the above embodiments are merely examples for clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the scope of protection of the claims created by the present invention.
