Description

Technical Field

[0001] The invention relates to the technical field of chemical industry, in particular to a production line of decorative braided materials and a production method thereof. Background Art

[0002] Decorative woven materials are an important material widely used in packaging, decoration and other fields. They not only need to have certain practicality, but also need to meet the market's demand for beautiful and diversified appearance. However, the common woven materials on the market still have many deficiencies in production technology and design, which seriously limit their promotion and application.

[0003] 1. Single structure and fixed form: At present, most decorative woven materials on the market are single-strip structures with a relatively single form, which is difficult to adapt to users' needs for diversified appearance and design styles. This single-strip structure lacks aesthetics and innovation in application, especially in high-end decoration scenes, and it is difficult to meet users' personalized requirements.

[0004] 2. Limited width and low processing efficiency: Since the width of existing woven materials is generally narrow, in the actual production process, a large number of repeated weaving operations are required to cover a large area. This not only increases production time, but also greatly reduces processing efficiency. In addition, the limited width of the material also requires frequent adjustments of the equipment, further affecting the overall production efficiency.

[0005] 3. Lack of design flexibility: Existing woven materials can usually only be produced in a single form, and it is difficult to adjust the size, pattern or other design elements according to demand. This limitation not only reduces its market competitiveness, but also fails to meet the needs of modern users for high-quality, personalized products.

[0006] 4. High production cost: As the existing process requires longer processing time and more operation steps to complete the same area of ​​products, the production cost per unit area is high, which is not conducive to large-scale promotion. At the same time, the over-reliance on manual operation has further increased production expenses.

[0007] 5. Low level of automation: Current production equipment generally has the problem of insufficient automation, especially in the forming, cooling and winding of woven materials, which usually requires a lot of manual intervention, which not only affects production efficiency, but also easily causes problems with inconsistent product quality. Summary of the invention

[0008] The purpose of the present invention is to overcome the shortcomings of the existing technology and provide a decorative woven material production line and its production method which has a simple structure, is easy to use, has high production efficiency, can effectively reduce the production time per unit area, and can also realize diversified design of the appearance, thereby meeting the diversified needs of the modern decorative material market.

[0009] The object of the present invention is achieved in the following manner: a production line for decorative braided materials, comprising a plastic extruder and a discharge die head installed at a discharge port thereof; A conveyor belt is arranged below the discharge die head, and the conveyor belt is driven by a power mechanism to move, and the hot melt plastic extruded from the discharge die head flows onto the conveyor belt; One end of the conveyor belt is also connected to a coiling machine, which rolls up and packs the finished decorative woven material that has been cooled and shaped.

[0010] Furthermore: the power mechanism is a speed regulating motor.

[0011] Furthermore: the conveyor belt is a belt-type PVC conveyor belt.

[0012] Furthermore: the conveyor belt is a chain-type stainless steel mesh conveyor belt.

[0013] Furthermore: a cooling fan is arranged above the conveyor belt.

[0014] Furthermore: the discharge end portion of the conveyor belt is immersed in a cooling water tank.

[0015] Furthermore: a traction machine is also arranged between the conveyor belt and the coiling machine.

[0016] Furthermore: a pressing mechanism is also arranged on the conveyor belt.

[0017] Furthermore: the conveyor belt is provided with two sets, front and rear, and a pressing mechanism is provided between the two sets of conveyor belts.

[0018] Furthermore: the discharge die head is also provided with a swing mechanism, and the swing mechanism drives the discharge die head to swing relative to the conveyor belt.

[0019] Furthermore: the swing mechanism includes an eccentric wheel driven by an eccentric motor, the eccentric wheel is connected to a driving arm through a connecting rod, the driving arm is hinged on the main machine, and the discharge die head is installed at the swing end of the driving arm.

[0020] A method for producing a decorative braided material comprises the following steps: S1: pouring plastic pellets into a plastic extruder, which is equipped with a discharge die; S2: There are several discharge holes on the discharge die head, and the hot melt plastic flows downward in a fluid state; S3: The hot-melt plastic flows onto the conveyor belt, which is driven by a power mechanism to move, and the conveyor belt drives the hot-melt plastic flowing onto the conveyor belt away from the discharge die head; S4: The hot melt plastic is cooled and shaped on the conveyor belt; S5: The finished decorative woven material that has been cooled and shaped enters the coiling machine for winding and packaging.

[0021] In the above S4, a plurality of cooling fans are arranged above the conveyor belt, and the cooling fans blow cold air toward the conveyor belt, so that the hot-melt plastic is cooled and shaped on the conveyor belt.

[0022] In the above-mentioned S4, the discharge end portion of the conveyor belt is immersed in a cooling water tank, so that the hot-melt plastic enters the cooling water tank for cooling and shaping.

[0023] The beneficial effects of the present invention are: 1. Simple structure, low production cost and improved market competitiveness.

[0024] 2. The present invention forms braided strips by hot melt extrusion. The hot melt plastic flows directly onto the conveyor belt through the discharge die head to be shaped. Different types of conveyor belts or different sections of the same conveyor belt—referring to plastics in a liquid state falling onto the conveyor belt surface from different discharge ports, because of the different places of contact with the conveyor belt surface, each strip of plastic in a liquid state forms different shapes on the conveyor belt, or arc-shaped, or connected, or separated, or partially overlapped, etc., so that braided materials with different appearances are produced after shaping. There is no need for complex manual weaving or multi-step processing procedures, and fully automated, continuous production, product appearance diversification, and disorder are realized. The power mechanism of the conveyor belt can be driven at an adjustable speed, which further optimizes the cooling and transmission efficiency of the hot melt plastic, greatly improving the overall production efficiency or product appearance differentiation.

[0025] 3. The design of the discharge die head in the present invention is highly flexible, and the number, distribution shape and arrangement of the material ports can be adjusted according to needs. By changing the structure of the discharge die head, different forms of plastic flow paths can be quickly switched to generate decorative woven materials with diverse appearances and sizes, meeting users' needs for personalized and diversified products.

[0026] 4. The design of the present invention allows for quick replacement of the discharge die head or adjustment of the operating parameters of the conveyor belt, thereby achieving the switching of different product forms. This flexibility not only simplifies the operation, but also shortens the production preparation time and improves the equipment utilization rate.

[0027] 5. Through hot melt extrusion and automatic conveyor belt cooling process, the product molding process is more uniform and stable, avoiding the common error problems in manual operation. At the same time, the cooling process can be further optimized through auxiliary devices such as cooling fans or cooling water tanks to ensure the shaping quality, aesthetics and production efficiency of the woven material.

[0033] The present invention is further described in detail below with reference to the accompanying drawings. A decorative braided material production line comprises a plastic extruder 1 and a discharge die head 2 installed at the discharge port thereof, wherein the blowing port on the discharge die head 2 is vertically arranged downward; A conveyor belt 3 is arranged below the discharge die head 2, and the conveyor belt 3 is driven by a power mechanism to move, and the hot melt plastic 4 extruded from the discharge die head 2 flows onto the conveyor belt 3; One end of the conveyor belt 3 is also connected to a coiling machine 5, which rolls up and packages the finished decorative woven material 6 that has been cooled and shaped.

[0034] In one embodiment, the power mechanism is a speed-regulating motor.

[0035] In one embodiment, the conveyor belt 3 is a belt-type PVC conveyor belt.

[0036] In one embodiment, the conveyor belt 3 is a chain-type stainless steel mesh conveyor belt.

[0037] In one of the embodiments, a cooling fan 7 is arranged above the conveyor belt 3 .

[0038] In one embodiment, the discharge end portion of the conveyor belt 3 is immersed in a cooling water tank.

[0039] In one embodiment, a traction machine 8 is further provided between the conveyor belt 3 and the coiling machine 5 .

[0040] In one of the embodiments, a profiling mechanism 9 is also provided on the conveyor belt. The profiling mechanism can be a roller, a pressing plate, etc. The user can set patterns and other designs on the profiling mechanism. When the profiling mechanism rolls over the hot-melt plastic 4 that has not yet cooled and formed, the pressure of the profiling mechanism is used to force it to deform or produce patterns on its surface, thereby further enriching the final product effect.

[0041] like Figure 5As shown, it should be noted that: the pressing mechanism 9 can also be separately arranged between the front and rear conveyor belts. The pressing mechanism is made of two upper and lower rollers that clamp each other. The hot-melt plastic 4 passes through the upper and lower rollers to be squeezed and shaped.

[0042] A method for producing a decorative braided material comprises the following steps: S1: pouring plastic granules into a plastic extruder 1, wherein the plastic extruder 1 is equipped with a discharge die 2; S2: The discharge die head 2 is provided with a plurality of discharge holes, and the hot melt plastic 4 flows downward in a fluid state; S3: The hot-melt plastic 4 flows onto the conveyor belt 3, and the conveyor belt 3 is driven by a power mechanism to move, and the conveyor belt 3 drives the hot-melt plastic 4 flowing onto the conveyor belt 3 away from the discharge die 2; S4: The hot melt plastic 4 is cooled and shaped on the conveyor belt 3; S5: The finished decorative braided material 6 that has been cooled and shaped enters the coiling machine 5 for winding and packaging.

[0043] In one of the embodiments, in the above S4, a plurality of cooling fans 7 are arranged above the conveyor belt 3, and the cooling fans 7 blow cold air toward the conveyor belt 3, so that the hot-melt plastic 4 is cooled and shaped on the conveyor belt 3.

[0044] In one of the embodiments, in S4, the discharge end portion of the conveyor belt 3 is immersed in a cooling water tank, so that the hot-melt plastic 4 enters the cooling water tank for cooling and shaping.

[0045] Working principle: Raw material preparation and hot melt extrusion: Plastic particles are first poured into the plastic extruder 1 as raw materials, and the extruder heats the plastic particles to a hot melt state through a heating system. The hot melt plastic is extruded through a discharge die 2 installed at the discharge port of the extruder.

[0046] The design of the discharge die 2 is highly flexible, and the distribution, number and shape of the discharge holes can be adjusted as needed, thereby determining the shape of the final product. For example, by increasing the number of discharge holes of the die or changing the arrangement of the holes, a decorative woven material with a wider width or a more complex pattern can be produced.

[0047] Since the hot melt extrusion process can achieve continuous flow and molding of plastic materials, it simplifies the complex processing steps of traditional woven materials and greatly improves production efficiency. At the same time, diversified product forms can be achieved by simply adjusting the die head.

[0048] Flow molding: The hot melt plastic flows from the discharge hole of the die head to the conveyor belt 3 under the action of gravity. The conveyor belt is driven by a power mechanism, and its speed can be adjusted by a speed regulating motor to meet the requirements of different flow speeds and material thickness or village material. The speed regulating motor can be a servo motor or a stepping motor.

[0049] The automatic operation of the conveyor belt ensures that the hot melt plastic can be evenly distributed and continuously conveyed, making the shape of the material more regular and the molding effect more stable. At the same time, the thickness of the final product can be adjusted by adjusting the conveyor belt movement speed and the stacking height.

[0050] like Figure 6 It should be noted that: a swing mechanism may also be provided at the discharge die head. When the plastic is extruded, the drop point of the hot-melt plastic on the conveyor belt is adjusted by swinging the discharge die head, so that the final formed woven strip presents a wave change.

[0051] The specific swing mechanism includes an eccentric wheel 10 driven by an eccentric motor, the eccentric wheel 10 is connected to a driving arm 12 through a connecting rod 11, the driving arm 12 is hinged on the main machine, and the discharge die head 2 is installed at the swing end of the driving arm 12. The eccentric wheel 10 is rotatable, and the eccentric setting of the hinge point between its rotation center and the connecting rod enables the connecting rod to push the driving arm to swing at a certain angle, thereby achieving the function of moving the position of the discharge die head. Among them, the eccentric motor can adopt a speed-regulating motor, so that the user can adjust the swing speed or swing position of the discharge die head conveniently, so as to meet more user needs.

[0052] Among them, in order to further enrich the product appearance, the plastic extruder 1 in this case can be set to multiple units, for example, 3 units are set, and the three devices extrude hot-melt plastics 4 of different colors or different cross-sections. The hot-melt plastics 4 flow on the conveyor belt at the same time, so that the hot-melt plastics 4 are mixed or contacted with each other or stacked on the conveyor belt, and finally after cooling and shaping, a mixing effect is formed.

[0053] 3. Cooling and shaping: After the hot melt plastic drips onto the conveyor belt 3, the plastic gradually cools and shapes as the conveyor belt moves. In order to speed up the cooling speed, the production line of the present invention can be provided with a cooling fan 7 above the conveyor belt to accelerate the cooling by blowing cold air onto the surface of the conveyor belt. In addition, a cooling water tank can be provided at the discharge end of the conveyor belt to allow the plastic to be quickly cooled in water to complete shaping.

[0054] In this case, a variety of cooling methods can be used to flexibly adapt to the cooling needs of different materials and thicknesses, ensure rapid shaping of materials, improve production efficiency, and reduce deformation or quality problems of thermoplastic materials caused by uneven cooling.

[0055] 4. Finished product conveying and winding: The finished decorative woven material 6 after cooling and shaping is conveyed to the coiler 5 through the conveyor belt, and the coiler completes the winding and packaging process. In this case, a traction machine 8 can also be set on the production line so that the traction mechanism can match the speed of the conveyor belt, so that the finished decorative woven material can be more stably and efficiently peeled off from the conveyor belt, thereby further improving the stability and efficiency of the transmission, ensuring uniform tension of the material during the transmission process, and avoiding curling or wrinkles.

[0056] Therefore, the automatic winding design greatly reduces manual intervention, making the finished products neat and orderly, facilitating subsequent storage and transportation, and significantly improving production efficiency.

[0057] In summary, the present invention realizes the integrated and automated production of decorative woven materials from raw materials to finished products through scientific design and efficient process flow, and provides an efficient, low-cost and diversified solution, so it can be widely promoted and used.

[0058] Obviously, the above embodiments are merely examples for the purpose of 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 therefrom are still within the scope of protection of the claims created by the present invention.
