Description

Technical Field

[0001] The present invention relates to the technical field of strip material production, in particular to a strip material production line and a process flow thereof. Background Art

[0002] The ribbon material is also called a belt. When it is made of silk thread inside and covered with plastic outside, it is also called a plastic-coated ribbon. It has the properties of strength, corrosion resistance and waterproofness.

[0003] At present, the application range of strip materials is very wide, including construction and civil engineering, industrial manufacturing and transportation. Its production line generally includes wire-paying components, wire components, injection molding components, cooling components and winding components.

[0004] However, since the tension of the wire running on the production line becomes increasingly unstable with increasing distance, it bends, resulting in undesirable arrangement, which affects the production quality of the strip material. At the same time, the cooled wire directly contacts the plastic fluid in the injection molding component, which leads to poor stability of the combination of the plastic fluid and the wire. The high-temperature strip material extruded by the injection molding component directly enters the cooling component (cold water tank) for cooling. Since the high-temperature strip material itself has high plasticity and enters the cold water tank from high to low, the surface of the strip material overflows and becomes uneven, affecting the wear resistance and corrosion resistance of the strip material, and greatly reducing the production quality of the strip material.

[0005] Therefore, a strip material production line and a process flow thereof are proposed. Summary of the Invention

[0006] The object of the present invention is to provide a strip material production line and a process flow thereof, so as to solve the problem of low production quality of strip materials existing in the existing strip material production line mentioned in the background art.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a strip material production line and a process flow thereof, comprising a pay-off stand, the pay-off stand being used for unwinding wire, a main threading stand being provided on one side of the pay-off stand, a platform frame being provided on the side of the main threading stand away from the pay-off stand, a wire dividing device, a tension roller device, a preheating device, a three-roller wire dividing device and a molding machine being sequentially provided on the platform frame, an air knife device and a cold water roller device being alternately provided on the side of the molding machine away from the three-roller wire dividing device, a cooling water trough being provided on the side of the alternating air knife device and the cold water roller device away from the molding machine, a traction device, a belt storage device, a meter-counting pressure roller device and a winding device being sequentially provided on the side of the platform frame away from the main threading stand.

[0008] Preferably, after passing through the main threading frame, the wire separation device, and the tension roller device, the plurality of wires are arranged at equal intervals, maintained at a constant tension, and enter the preheating device for heating.

[0009] Preferably, the plurality of silk threads are heated by a preheating device and then passed through a three-roller silk separation device and arranged at equal intervals with constant tension.

[0010] Preferably, a plurality of the filaments arranged at equal intervals and with constant tension enter a molding machine and are compression-molded into a strip-shaped material.

[0011] Preferably, the air knife device, the cold water roller device and the cooling water trough are used to cool the strip material.

[0012] Preferably, the traction device is used to pull the strip material, and the strip storage device is used to store the strip material.

[0013] Preferably, the meter-counting roller device is used to measure the length of the strip material, and the winding device is used to wind up the strip material.

[0014] Preferably: five air knife devices are provided on the platform frame, and four cold water roller devices are provided on the platform frame. The order of alternating arrangement of the air knife devices and the cold water roller devices is: the air knife device first, then the cold water roller device, and finally the air knife device, with the side of the molding machine away from the three-roller wire separating device as the starting end.

[0015] Preferably, the pay-off frame, main threading frame, platform frame, traction device, tape storage device, meter-counting roller device and winding device are all arranged on the ground and located on the same horizontal line.

[0016] Preferably, the molding machine comprises a main body and a mold, the mold in the molding machine is arranged on a platform frame, and the main body of the molding machine is arranged on the ground on one side of the platform frame.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. This production line has a wire-splitting device placed in front of a tension roller device, which in turn is placed in front of a preheating device. The wire-splitting device is used to perform coarse wire-splitting operations on a number of wires, thus avoiding the stacking of a number of wires and affecting the constant tension of the tension roller device and the sufficient heating of the preheating device. This is more conducive to the better combination of the heated wires with the plastic fluid in the molding machine after entering the molding machine. Because the three-roller wire-splitting device subdivides the wires and adjusts the constant tension, the wires inside the strip material extruded by the molding machine are arranged at equal intervals, thereby making the strength of the strip material balanced, greatly improving the quality of the strip material produced by this production line.

[0019] 2. This device uses air knife devices and cold water roller devices arranged alternately and placed in front of the cooling water tank. At the same time, it uses air cooling and heat exchange to perform multiple cooling on the high-temperature strip materials, avoiding the high-temperature strip materials from being deformed due to their own plasticity and under the influence of gravity, thereby improving the production quality of the strip materials. The air knife devices and cold water roller devices are placed in front of the cooling water tank, so that the high-temperature strip materials are initially cooled before entering the cooling water in the cooling water tank, avoiding the splashing caused by the high-temperature strip materials directly contacting the cooling water and polluting the production environment. At the same time, it avoids the deformation caused by the high-temperature strip materials entering the cooling water in the cooling water tank from high to low due to their high plasticity and under the action of their own gravity, thereby making the surface of the strip materials produced by this production line smoother, with balanced wear resistance and corrosion resistance, improved quality and improved aesthetics.

[0031] Reference Figure 1-6 As shown, the present invention provides a technical solution for a strip material production line and its process flow:

[0032] A strip material production line includes a pay-off stand 1, which is used to unwind a wire 2. A main threading stand 3 is provided on one side of the pay-off stand 1, and a platform frame 11 is provided on the side of the main threading stand 3 away from the pay-off stand 1. A wire dividing device 4, a tension roller device 5, a preheating device 6, a three-roller wire dividing device 7 and a molding machine 8 are sequentially arranged on the platform frame 11. An air knife device 9 and a cold water roller device 10 are alternately arranged on the side of the molding machine 8 away from the three-roller wire dividing device 7. A cooling water trough 12 is provided on the side of the alternating air knife device 9 and the cold water roller device 10 away from the molding machine 8. A traction device 13, a belt storage device 14, a meter-counting pressure roller device 15 and a winding device 16 are sequentially provided on the side of the platform frame 11 away from the main threading stand 3.

[0033] It should be noted that, referring to Figure 1 and Figure 2As shown, the main threading frame 3 is located on the left side of the pay-off frame 1, the platform frame 11 is located on the left side of the main threading frame 3, the traction device 13 is located on the left side of the platform frame 11, the tape storage device 14 is located on the left side of the traction device 13, the meter-counting pressure roller device 15 is located on the left side of the tape storage device 14, and the winding device 16 is located on the left side of the meter-counting pressure roller device 15. The wire dividing device 4, the tension roller device 5, the preheating device 6, the three-roller wire dividing device 7, the molding machine 8 and the alternatingly arranged wind knife devices 9 and the cold water roller device 10 are arranged from right to left on the platform frame 11.

[0034] Among them, it needs to be supplemented that, after passing through the main threading frame 3, the wire dividing device 4, and the tension roller device 5, the several wires 2 are arranged at equal intervals, with constant tension, and enter the preheating device 6 for heating. After being heated by the preheating device 6, the several wires 2 pass through the three-roller wire dividing device 7 with constant tension and equal intervals. After the several wires 2 are arranged with constant tension and equal intervals, they enter the molding machine 8 and are pressed into strip materials.

[0035] Among them, it needs to be supplemented that, the wire dividing device 4 is used to roughly arrange several wires 2 at equal intervals, that is, coarse wire dividing, the purpose of which is to avoid stacking of several wires 2, thereby affecting the constant tension of the tension roller device 5 on the several wires 2 and affecting the heating of the several wires 2 by the preheating device 6. The purpose of heating the several wires 2 is to facilitate them to better combine with the plastic fluid in the molding machine 8 after entering the molding machine 8, and to be extruded into strip materials. Correspondingly, the three-roller wire dividing device 7 is used to finely arrange several wires 2 heated by the preheating device 6 at equal intervals, that is, fine wire dividing, the purpose of which is to make the arrangement of several wires 2 inside the strip material formed by the molding machine 8 equal, so that the strength of the strip material is balanced, thereby improving the quality of the strip material produced by this production line.

[0036] The three-roller wire separating device 7 is also used to adjust and maintain the tension of the plurality of wires 2 to prevent the plurality of wires 2 from bending during transportation, thereby affecting their equal spacing arrangement.

[0037] It should be noted that if the plurality of wires 2 are not heated, after they enter the molding machine 8, when the high-temperature plastic fluid in the molding machine 8 contacts the low-temperature plurality of wires 2, before the two are fully in contact, the area where the plastic fluid is close to the plurality of wires 2 will cool down rapidly, making the bond between the plastic fluid and the wires 2 unstable, thereby making the plurality of wires 2 inside the extruded strip material easy to shake or even fall off, thereby greatly reducing the strength of the strip material.

[0038] Among them, it should be supplemented that the air knife device 9, the cold water roller device 10 and the cooling water trough 12 are used to cool the strip material, the traction device 13 is used to traction the strip material, the belt storage device 14 is used to store the strip material, the meter pressure roller device 15 is used to measure the length of the strip material, and the winding device 16 is used to wind up the strip material. Among them, the air knife device 9 uses air cooling to cool the strip material, and the cold water roller device 10 and the cooling water trough 12 both use heat exchange to cool the strip material. It should be noted that the reason why the air knife device 9 and the cold water roller device 10 are alternately arranged and located in front of the cooling water trough 12 is that The reason for this is that the hot strip material exiting the molding machine 8 is still plastic. If it were to enter the cooling water tank 12 directly, firstly, due to the high temperature of the strip material, it would directly contact the cooling water in the cooling water tank 12 and cause splashing, thereby contaminating the production line. Secondly, because the strip material enters the cooling water in the cooling water tank 12 from a high position, before it contacts the cooling water, the hot strip material is still plastic. Under the action of its own gravity, the surface of the strip material will overflow, resulting in an uneven surface, uneven wear resistance and corrosion resistance, and a degraded quality and unsightly appearance. The alternating arrangement of the air knife device 9 and the cold water roller device 10 not only utilizes air cooling and heat exchange to reduce the temperature of the hot strip material, but also, because the cold water roller device 10 can support the hot strip material, the surface tension of the hot strip material is stabilized, preventing deformation due to its own plasticity under the action of gravity, thereby improving the production quality of the strip material.

[0039] Reference Figure 3 As shown, in an optional embodiment, five air knife devices 9 are provided on the platform frame 11, and four cold water roller devices 10 are provided on the platform frame 11. The order of alternating arrangement of the air knife devices 9 and the cold water roller devices 10 is with the side of the molding machine 8 away from the three-roller wire separating device 7 as the starting end, the air knife device 9 first, the cold water roller device 10 second, and the air knife device 9 last.

[0040] Reference Figure 5 and Figure 6 As shown, the pay-off frame 1, main threading frame 3, platform frame 11, traction device 13, tape storage device 14, meter-counting roller device 15, and winding device 16 are all installed on the ground 17 and are located on the same horizontal line. This arrangement allows personnel to monitor the operation of the production line from both sides and make timely adjustments and maintenance on various devices on the production line.

[0041] Among them, it needs to be supplemented that the molding machine 8 includes a main body and a mold. It should be noted that this is the existing technology and will not be elaborated on here. The mold in the molding machine 8 is set on the platform frame 11, and the main body of the molding machine 8 is set on the ground 17 on one side of the platform frame 11.

[0042] This production line is provided with a tension roller device 5 in front of a wire dividing device 4, and the tension roller device 5 is provided in front of a preheating device 6. The wire dividing device 4 is used to perform a coarse wire dividing operation on a plurality of wires 2, thereby avoiding the stacking of a plurality of wires 2 and affecting the constant tension of the tension roller device 5 and the sufficient heating of the preheating device 6. This is more conducive to the better combination of the heated wires 2 with the plastic fluid in the molding machine 8 after entering the molding machine 8. Because the three-roller wire dividing device 7 subdivides the plurality of wires 2 and adjusts the constant tension, the arrangement of the plurality of wires 2 inside the strip material extruded by the molding machine 8 is equal, thereby making the strength of the strip material balanced, greatly improving the quality of the strip material produced by this production line.

[0043] This device arranges the wind knife device 9 and the cold water roller device 10 alternately and places them in front of the cooling water trough 12. At the same time, it uses air cooling and heat exchange to perform multiple cooling on the high-temperature strip material, avoiding the high-temperature strip material from being deformed due to its own plasticity and under the influence of gravity, thereby improving the production quality of the strip material. The wind knife device 9 and the cold water roller device 10 are placed in front of the cooling water trough 12, so that the high-temperature strip material is initially cooled before entering the cooling water in the cooling water trough 12, avoiding the splashing caused by the high-temperature strip material directly contacting the cooling water and polluting the production environment. At the same time, it avoids the deformation caused by the high-temperature strip material entering the cooling water in the cooling water trough 12 from high to low due to its high plasticity and under the action of its own gravity, thereby making the surface of the strip material produced by this production line smoother, with balanced wear resistance and corrosion resistance, improved quality and improved aesthetics.

[0044] The process flow of a strip material production line is as follows: the first step: a plurality of wires 2 are unwound by a wire pay-off stand 1, the heights of the plurality of wires 2 are adjusted to adapt to a wire-splitting device 4 by a main wire-threading stand 3, a coarse wire-splitting operation is performed on the plurality of wires 2 by the wire-splitting device 4, and the tension of the plurality of wires 2 that have undergone the coarse wire-splitting operation is adjusted and maintained constant by a tension roller device 5; the second step: a preheating device 6 is used to heat the plurality of wires 2 that have undergone the coarse wire-splitting operation and the tension-regulating constant operation; the third step: a three-roller wire-splitting device 7 is used to finely divide the plurality of wires 2 that have undergone the coarse wire-splitting operation, the tension-regulating constant operation, and the heating operation; the Step 4: Extrusion molding operation is performed on several wires 2 that have undergone coarse wire splitting operation, constant tension adjustment operation, heating operation, and fine wire splitting operation through the molding machine 8, and the high-temperature strip material is output through the molding machine 8; Step 5: Preliminary cooling of the high-temperature strip material is performed through the air knife device 9 and the cold water roller device 10, and further cooling of the preliminarily cooled strip material is performed through the cooling water trough 12; Step 6: The strip material is pulled by the pulling device 13; Step 7: The strip material is stored by the strip storage device 14; Step 8: The length of the strip material is measured by the meter pressure roller device 15; Step 9: The strip material is wound up by the winding device 16.

[0045] It should be noted that the reason why the belt storage device 14 is set up to store the strip material is that after the winding device 16 is full of strip material, it needs to be manually disassembled and replaced, which will delay the production line for a certain period of time. At this time, the strip material is temporarily stored through the belt storage device 14, so that the production line can continue to operate during the disassembly and replacement of the winding device 16, thereby significantly improving the efficiency of the production line in producing strip materials.

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