Description

Technical Field

[0001] The invention relates to the technical field of a heat recycling type fabric coating machine, and in particular to a heat recycling type fabric coating machine. Background Art

[0002] A laminator is a device used to coat or cover a material with a film. It usually consists of a set of drums or roller systems that apply the film or coating evenly to the surface of the substrate through heat and pressure. The types and uses of laminators can be adjusted as needed, covering a variety of industrial and commercial applications. Fabric laminators are a special type of laminator that are specifically used to apply films or coatings to fabric surfaces. They usually have special designs suitable for handling soft and elastic fabrics to ensure that the fabric is not damaged or unevenly coated during the laminating process. Fabric laminators are usually equipped with appropriate heating systems and pressure regulation devices to ensure that the fabric can remain flat during the laminating process and bond well with the film or coating.

[0003] In the prior art, the Chinese invention disclosed as "CN111168987B" is a non-woven fabric laminating equipment, whose main structure includes a body, a retractable rack, a push rod, a laminating machine, and a shaping structure, the retractable rack is installed on the right side of the body and is hinged, the push rod is movably connected between the bodies, the laminating machine is horizontally installed on the upper end of the body and is mechanically connected, the shaping structure is installed on the upper end of the body and is arranged on the left side of the laminating machine; the shaping structure includes a driving box, a ramp, a roller, a hot pressing structure, a pressing plate, and a discharging table, the ramp is arranged between the driving boxes and is an integrated structure, the roller is embedded and installed between the driving boxes and is mechanically connected, the hot pressing structure is horizontally installed between the driving boxes, the pressing plate is arranged on the left side of the upper surface of the ramp, the discharging table is installed at the front end of the driving box and welded to each other, and the pressing plate is located above the discharging table.

[0004] The above technology strengthens the pressing of the edges of the non-woven fabric and the film through the hot pressing structure and the elastic structure. During pressing, the edge pressing ring contacts the edge of the film and is stretched or compressed by the force to better press the edges of the non-woven fabric and the film, preventing the non-woven fabric and the film from detaching from the edges during use, making the overall pressing more firm and increasing the service life. However, it still contains the following technical problems: during hot pressing, after the hot pressing roller presses the fabric, the cylindrical surface of the hot pressing roller will continuously exchange heat with the surrounding air, and the temperature of the workshop needs to be lowered to offset this heat, resulting in energy loss and waste, that is, increasing energy consumption and increasing the cost of use. Summary of the invention

[0005] The present invention proposes a heat recycling type fabric coating machine, which recycles the heat emitted by the hot pressing roller, uses the excess heat to preheat the fabric surface, increases energy utilization, improves the coating effect of the fabric, and reduces the use cost.

[0010] One side of the heat preservation chamber is connected with a pulling component for oscillating and pulling the preheated fabric.

[0011] Furthermore, the pulling assembly includes a driving motor and two first gears, the two first gears are rotatably connected to the film-covering bracket, the upper side of each first gear is meshed with a transmission rack, each transmission rack is slidably connected to two limit columns, and each limit column is fixedly connected to the outer side of the insulation bin;

[0012] The transmission rack is slidably connected to one side of the heat preservation bin with two locking columns, and each of the locking columns is fixedly connected to one end of the transmission rack with one end away from the transmission rack, and a first flip plate is hinged on the first limiting plate, and each of the first flip plates is hinged to a second flip plate at one end away from the first limiting plate, and two second flip plates are hinged to a second limiting plate at one end away from the first flip plate, and the second limiting plate is fixedly connected to the film covering bracket, and the first flip plate and the second flip plate are rotatably connected to a pulling cylinder at the hinged position;

[0013] The driving motor is fixedly connected to the outside of the coating support, and the driving shaft of the driving motor is fixedly connected to the first gear.

[0014] Furthermore, each of the positioning columns is sleeved with a shock absorbing spring, and two ends of the shock absorbing spring are respectively in contact with the transmission rack and the first limiting plate.

[0015] Furthermore, each of the first gears is rotatably connected to one side facing each other, and the linkage plate is rotatably connected to the second gear at one end away from the axis of the first gear. The second gear is meshed with the first gear, and a hammering disk is coaxially connected to the side of the linkage plate away from the second gear. The hammering disk is fixedly connected to the second gear, and a number of hammering cylinders are rotatably connected between the two hammering disks.

[0016] Furthermore, a plurality of locking strips are fixedly connected to the cylindrical surface of the pulling cylinder.

[0017] Furthermore, the linkage assembly includes a third gear, which is coaxially fixedly connected to the hot pressure roller, and a fourth gear is meshed on the third gear. The fourth gear is rotatably connected to the lower side of the insulation plate, and a first synchronous wheel and a second synchronous wheel are rotatably connected to the upper side of the insulation plate.

[0019] The beneficial effects of the present invention are:

[0020] The rotating heat pressing of the hot pressing roller on the fabric can be transmitted to the temperature return fan through the linkage component, so that the temperature return fan can rotate, and then the temperature return fan generates upward wind force in the insulation chamber. When the hot pressing roller rotates and heats, the cylindrical surface will exchange heat with the surrounding air, so that the air under the insulation board is heated, and the wind force generated by the temperature return fan moves the heated gas upward, so that the heat can be preheated with the surface of the fabric. The fabric may absorb a certain amount of moisture or volatiles during the production and storage process. Through this preheating, these moisture and volatiles can be evaporated, thereby reducing the adverse effects in the subsequent hot pressing process. At the same time, after the fabric is preheated, the fibers and yarns may be more relaxed, which helps the fabric and the coating film to fit more flatly in the subsequent hot pressing process, thereby improving the uniformity and integrity of the coating. In addition, preheating helps prevent excessive heat shrinkage of the fabric during the hot pressing process, and reduces the dimensional changes caused by heat by releasing some internal tension and stress in the fabric in advance, thereby improving the effect of fabric coating.

[0021] The reheating fan moves upward with the hot air through the air discharge slot, and through the gaps in the fabric, so that the surface of the preheating cylinder continuously exchanges heat with the hot air, and then the preheating cylinder also has temperature. When the preheating cylinder is limited to the fabric, the upper and lower sides of the fabric can be preheated to ensure the preheating effect of the fabric. At the same time, the hot air with residual heat will flow to the reheating bin, and then rotate a circle and flow back from the reheating trough to the insulation bin, reducing heat loss and increasing energy utilization.

[0022] The pulling component can stretch and beat the preheated fabric surface, and with the preheating effect, the fabric surface is made flatter, and the dust attached to the fabric surface can be better separated from the fabric through beating and stretching, thereby improving the bonding effect between the fabric 5 and the coating film;

[0023] In summary, the heat emitted by the hot pressing roller is recycled, the excess heat is used to preheat the surface of the fabric, and then the preheating treatment is carried out by coordinating the components to improve the coating effect of the fabric. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] like Figure 1 to Figure 6 As shown, this embodiment proposes a heat recycling type fabric film coating machine, comprising a film coating support 11, a workbench 12 and a hot pressing roller 13 for hot rolling the fabric 5 and the coating film 6, the workbench 12 is fixedly connected to the film coating support 11, and the hot pressing roller 13 is fixedly connected to the workbench 12;

[0034] A heat preservation bin 19 is fixedly connected to the film coating support 11, the workbench 12 and the hot pressing roller 13 are both arranged in the heat preservation bin 19, the insulation plate 18 is fixedly connected in the heat preservation bin 19, the temperature recovery fan 14 is rotatably connected to the insulation plate 18, and the linkage component is connected between the temperature recovery fan 14 and the heat pressing roller 13. Through the linkage component, the rotational heat pressing of the hot pressing roller 13 on the fabric 5 can be transmitted to the temperature recovery fan 14, so that the temperature recovery fan 14 can rotate, and then the temperature recovery fan 14 generates an upward wind force in the heat preservation bin 19. When the hot pressing roller 13 rotates and heats, the cylindrical surface will exchange heat with the surrounding air, so that the air on the lower side of the insulation plate 18 is heated, and the wind force generated by the temperature recovery fan 14 will heat the heated gas. Move upward so that the heat can be preheated with the surface of the fabric 5. The fabric 5 may absorb a certain amount of moisture or volatiles during production and storage. This preheating can help evaporate these moisture and volatiles, thereby reducing the adverse effects in the subsequent hot pressing process. At the same time, after the fabric 5 is preheated, the fibers and yarns may be more relaxed, which helps in the subsequent hot pressing process. The fabric 5 and the coating film 6 can fit more flatly, thereby improving the uniformity and integrity of the coating. In addition, preheating helps prevent excessive heat shrinkage of the fabric 5 during the hot pressing process, and by releasing some internal tension and stress in the fabric 5 in advance, the dimensional change caused by heat is reduced, and the coating effect of the fabric 5 is improved;

[0035] The reheating bin 15 is fixedly connected to the upper side of the heat preservation bin 19, and the preheating cylinder 16 for preheating the surface of the fabric 5 is rotatably connected to the reheating bin 15. The air discharge slot 191 is opened on the upper wall of the reheating bin 15, and two reheating slots 192 are opened on both sides of the air discharge slot 191. The heat preservation bin 19 is connected to the reheating bin 15 through the reheating slot 192. The reheating fan 14 moves upward with the hot air through the air discharge slot 191, and passes through the gap of the fabric 5, so that the surface of the preheating cylinder 16 is continuously heat-exchanged with the hot air, so that the preheating cylinder 16 also has temperature, so that when the preheating cylinder 16 is limited to the fabric 5, the upper and lower sides of the fabric 5 can be preheated to ensure the preheating effect of the fabric 5. At the same time, the hot air with residual heat will flow into the reheating bin 15, and then rotate a circle and flow back to the heat preservation bin 19 from the reheating slot 192, thereby reducing heat loss and increasing energy utilization.

[0036] The pulling component 2 for oscillating and pulling the preheated fabric 5 is connected to one side of the insulation chamber 19. The pulling component 2 can stretch and beat the surface of the preheated fabric 5, and cooperate with the preheating effect to make the surface of the fabric 5 flatter. Through beating and stretching, the dust attached to the surface of the fabric 5 can be better separated from the fabric 5, thereby improving the fitting effect between the fabric 5 and the coating film 6, that is, improving the coating effect of the fabric 5.

[0037] like Figure 1 to Figure 4As shown, the pulling assembly 2 includes two first gears 21, which are rotatably connected to the film-covered support 11, and the upper side of each first gear 21 is meshed with each transmission rack 22, and each transmission rack 22 is slidably connected with two limit columns 23, and each limit column 23 is fixedly connected to the outer side of the insulation bin 19. The sliding of the transmission rack 22 is limited by the two limit columns 23 to ensure that the transmission rack 22 will not deviate when sliding;

[0038] The transmission rack 22 is slidably connected to the two positioning columns 24 on the side away from the insulation bin 19, and each positioning column 24 is fixedly connected to the first limiting plate 25 at one end away from the transmission rack 22, and the first limiting plate 25 is hinged to the first flip plate 26, and each first flip plate 26 is hinged to the second flip plate 27 at one end away from the first limiting plate 25, and the two second flip plates 27 are hinged to the second limiting plate 28 at one end away from the first flip plate 26, and the second limiting plate 28 is fixedly connected to the film coating bracket 11, and the pulling cylinder 29 is rotatably connected to the first flip plate 26 and the second flip plate 27 at the hinged position. When the transmission rack 22 moves toward the first limiting plate 25, it will change the angle between the first flip plate 26 and the second flip plate 27, thereby changing the distance between the two pulling cylinders 29, and the two pulling cylinders 29 can complete the stretching of the fabric 5, so that the fabric 5 that has been preheated can be further relaxed, so that the fabric 5 can better fit with the coating film 6, thereby improving the uniformity and integrity of the coating.

[0039] like Figure 1 to Figure 4 As shown, each shock-absorbing spring 241 is sleeved on each positioning column 24, and the two ends of the shock-absorbing spring 241 are respectively in contact with the transmission rack 22 and the first limit plate 25, so that when the transmission rack 22 drives the two pulling cylinders 29 to pull the fabric 5, under the action of the shock-absorbing spring 241, the tension of the fabric 5 itself will not be destroyed by the excessive pulling force of the two pulling cylinders 29, thereby ensuring the fabric 5 itself. At the same time, when the fabric 5 itself is beaten by the beating cylinder 34, the shock-absorbing spring 241 can be used for shock absorption and buffering.

[0040] like Figure 2 and Figure 4As shown, each linkage plate 31 is rotatably connected to the opposite side of each first gear 21, and the linkage plate 31 is rotatably connected to the second gear 32 at one end away from the axis of the first gear 21, and the second gear 32 is meshed with the first gear 21. The linkage plate 31 is coaxially connected to the beating disk 33 at one side away from the second gear 32, and the beating disk 33 is fixedly connected to the second gear 32. A number of beating cylinders 34 are rotatably connected between the two beating disks 33. The rotation of the first gear 21 drives the second gear 32 to rotate, and then drives a number of beating cylinders 34 to beat the surface of the preheated fabric 5. Preheating can help evaporate moisture and volatiles in these fabrics 5, thereby reducing adverse effects in subsequent hot pressing processes. After the knitted fabric 5 is preheated, the fibers and yarns may be more relaxed, which helps to fit the fabric 5 more flatly with the coating film 6 in the subsequent hot pressing process, thereby improving the uniformity and integrity of the coating.

[0041] like Figure 1 to Figure 3 As shown, a plurality of retaining strips 291 are fixedly connected to the cylindrical surface of the pulling cylinder 29. The retaining strips 291 can limit the stretching of the surface of the preheated fabric 5. Under the same pressure, the smaller the contact area, the greater the pressure. Even when the fabric 5 is pulled by the pulling cylinder 29, it will not be easily displaced and can better cooperate with the pulling cylinder 29 to work.

[0042] like Figure 5 and 6 As shown, the linkage assembly includes a third gear 41, the third gear 41 is coaxially fixedly connected to the hot pressing roller 13, the third gear 41 is meshed with the fourth gear 42, the fourth gear 42 is rotatably connected to the lower side of the insulation plate 18, the first synchronous wheel 43 and the second synchronous wheel 44 are both rotatably connected to the upper side of the insulation plate 18, the first synchronous wheel 43 is coaxially fixedly connected to the fourth gear 42, the second synchronous wheel 44 is fixedly connected to the temperature recovery fan 14, and the synchronous belt 45 is meshed on the first synchronous wheel 43 and the second synchronous wheel 44. The temperature recovery fan 14 is driven to rotate by the rotation of the hot pressing roller 13. The gear ratio between the third gear 41 and the fourth gear 42 can be adjusted, so that the temperature recovery fan 14 can generate sufficient suction through the rotation of the hot pressing roller 13, and the heat exchange between the hot pressing roller 13 and the surrounding air can be transferred, so that this energy can be further utilized, thereby increasing the coating effect of the fabric 5, while reducing energy loss and increasing energy utilization.

[0043] like Figure 5 and 6As shown, the wind gathering ring 17 is fixedly connected to the insulation plate 18. The wind gathering ring 17 can gather the wind force generated by the temperature return fan 14 and guide the wind direction. The heat flow exchanged with the air around the hot pressing roller 13 can pass through the circulation hole 181 more concentratedly through this wind, and then blow towards the surface of the fabric 5 on the upper side. Even if the surface of the fabric 5 passes through the preheating cylinder 16, it can be preheated in advance, so that the surface of the fabric 5 can be better stretched, and the fabric 5 can be better bonded to the surface film when passing through the hot pressing roller 13, thereby increasing the effect of subsequent coating of the fabric 5. The air avoidance groove 171 for avoiding the synchronous belt 45 is opened on the wind gathering ring 17, and a plurality of circulation holes 181 are opened on the insulation plate 18 with the axis of the wind gathering ring 17 as the center.

[0044] The principle of this embodiment is:

[0045] The fabric 5 is unwound from the unwinding machine, and then the unwound fabric 5 is sequentially contacted and wound with the preheating cylinder 16, two pulling cylinders 29, a plurality of beating cylinders 34, and the hot pressing roller 13, and the coating film 6 is installed above the entrance of the heat preservation bin 19, and then one end of the coating film 6 is coated with the fabric 5, and then the two fabrics are passed through the gap between the workbench 12 and the hot pressing roller 13, and finally moved out from the exit end of the heat preservation bin 19, and then the coated fabric 5 is wound through the winding machine;

[0046] By means of electric heating, the cylindrical surface of the hot pressing roller 13 generates heat, and then through the winding of the winding machine, the fabric 5 abuts against the hot pressing roller 13, driving the hot pressing roller 13 to rotate, and the fabric 5 and the coating film 6 are better fitted together by means of hot rolling. At the same time, the rotation of the hot pressing roller 13 can drive the third gear 41 and the fourth gear 42 to rotate in conjunction, and then the first synchronous wheel 43 and the second synchronous wheel 44 are engaged with the synchronous belt 45 to drive the temperature return fan 14 to rotate, and the gear ratio between the third gear 41 and the fourth gear 42 is adjusted, so that the temperature return fan 14 generates sufficient wind. The force can move the heat flow on the lower side of the insulation board 18 upward, so that the heat flow can preheat the fabric 5 on the upper side. At the same time, the hot air contacts the preheating cylinder 16 through the gap on the fabric 5, so that the temperature of the surface of the preheating cylinder 16 also rises, so that the upper and lower surfaces of the fabric 5 passing through the preheating cylinder 16 are preheated, and then part of the hot air continues to rise, and then refluxes in the temperature recovery bin 15, and finally flows back into the insulation bin 19 from the temperature recovery tank 192, and continues to move upward with the heating, and preheats the surface of the fabric 5, thereby increasing the energy utilization rate and improving the coating effect of the fabric 5;

[0047] The driving motor 210 drives the first gear 21 to rotate regularly forward and reverse:

[0048] When the first gear 21 rotates forward, it will move the meshed transmission rack 22 toward the first limit plate 25, so that the two pulling cylinders 29 move in opposite directions, and then stretch the fabric 5. The force of the shock-absorbing spring 241 can prevent the pulling force of the pulling cylinder 29 from damaging the fabric 5 itself, thereby ensuring that the fabric 5 will not be damaged during the stretching. Then the first gear 21 will also rotate with the second gear 32, and will rotate with the linkage plate 31 around the axis of the first gear 21, so that the rotating beating cylinders 34 continuously stretch the fabric 5, and at the same time vibrate the surface of the fabric 5, so that the dust and debris attached to the surface of the fabric 5 are shaken off;

[0049] When the first gear 21 reverses, it will move the meshed transmission rack 22 away from the first limit plate 25 and move the two pulling cylinders 29 in opposite directions, thereby relaxing the fabric 5. The surface of the preheated fabric 5 becomes flatter due to the tension and relaxation, thereby increasing the bonding effect between the fabric 5 and the coating film 6.

[0050] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
