Description

Technical Field

[0001] The present invention relates to the technical field of film coating equipment, and in particular to a high-temperature hot-pressing film coating equipment. Background Art

[0002] The principle of fabric lamination is to fix the film material on the surface of the fabric by heat pressing or coating to form a protective film. This film can play a role in waterproofing, dustproofing, and anti-fouling, and can also increase the strength and softness of the fabric. The lamination material is usually made of synthetic materials such as polyvinyl chloride (PVC) and polyurethane (PU), which have good durability and weather resistance.

[0003] The fabric and film material pass through two hot pressing rollers, and the film material is melted on the fabric. However, due to the different fabric materials and thicknesses, the distance between the two hot pressing rollers needs to be controlled. If the distance is too large, it cannot ensure that the film material can be tightly melted on the fabric. If the distance is too small, the fabric will be over-pressed and the quality of the fabric cannot be maintained after production. At the same time, the distance between the two hot pressing rollers must be kept constant during operation. Summary of the invention

[0004] In order to solve the above problems, the present invention discloses a high-temperature hot-pressing film laminating device, comprising a frame, a first heating roller and a second heating roller are arranged side by side inside the frame, and the second heating roller is located below the first heating roller, and a support frame, the middle part of the support frame is rotatably connected to the frame, and the end of the second heating roller is rotatably matched to the upper side of the support frame. The fabric and the film pass between the first heating roller and the second heating roller, and the film is hot-melted and bonded to the fabric.

[0005] The frame is fixedly connected with a cylinder, and the output end of the cylinder extending upward is rotatably connected with one side of the support frame. When the cylinder works, the output end thereof extends or retracts, causing the support frame to deflect, and then the support frame deflects, thereby adjusting the angle between the first heating roller and the second heating roller.

[0006] A shaft roller is provided on one side of the first heating roller and the second heating roller for lifting. The shaft roller here is used to adjust the wrap angle between the fabric and the first heating roller or the second heating roller, so as to control the heating time.

[0007] Two sets of unwinding mechanisms and a conveying mechanism are arranged inside the frame, and air pipes are arranged between the unwinding mechanisms and the conveying mechanisms, and through holes are opened on the side walls of the air pipes downward. The two sets of unwinding mechanisms release two layers of film, and the purpose of the air pipes is to blow the gas sent from the through holes of the air pipes on the film to make it smoother and adjust the tension of the film.

[0008] Preferably, the side wall of the frame is fixedly connected with a shell, one end of the shell is extended with a telescopic rod, the end of the telescopic rod is fixedly connected with a support block, and the support block is directly opposite to the side rod preset at the bottom of the support frame. When the support frame is deflected by the cylinder, in order to avoid the gap between the first heating roller and the second heating roller being too small, which causes the fabric to be clamped and damaged, a support block and a telescopic rod are provided to limit the deflection angle of the support frame, and a pressure relief valve is provided on the air intake pipeline of the cylinder. The pipeline is always filled with gas to ensure that the gap between the first heating roller and the second heating roller is always maintained, so that the fabric quality is consistent.

[0009] Preferably, a worm gear is provided inside the housing, and a rotating shaft is fixedly connected to the middle of the worm gear. By rotating the rotating shaft, the worm gear is transmitted, and the telescopic rod is extended or retracted, and the limit of the deflection angle of the support frame is adjusted, that is, the minimum distance between the first heating roller and the second heating roller is controlled, so as to be suitable for processing fabrics of different thicknesses.

[0010] Preferably, the conveying mechanism includes a rod, which is surrounded by a plurality of cylindrical members, and sliding blocks are provided at both ends of the rod, one of which is fixedly connected to a driving motor, and a belt is provided at the output end of the driving motor and the end of the rod. The driving motor is started, and the belt is driven to drive the rod to rotate. At the same time, under the action of wind pressure, it is ensured that the film and the rod are in full contact, and sufficient friction is ensured, so that the rod rotates to transport the fabric. At the same time, the rod is composed of a plurality of cylindrical members, so that the contact area between the film and the rod is reduced as much as possible.

[0011] Preferably, a fixed block is provided below the sliding block, a screw is inserted into the fixed block, the end of the screw is matched with the sliding block, a handle is provided on the fixed block, and a worm gear is provided between the handle and the screw. By turning the handle, the screw is raised and lowered in coordination with the worm gear, thereby changing the position of the sliding block, that is, changing the height of the rod.

[0012] Preferably, transmission boxes are provided at both ends of the frame, and components such as a motor and an air pump are provided inside the transmission box.

[0013] The beneficial effects of the present invention are as follows: 1. A support frame is provided, and the second heating roller is rotatably matched on the support frame. The cylinder works to drive the support frame to deflect, thereby adjusting the distance between the first heating roller and the second heating roller, so as to be suitable for processing different thicknesses.

[0014] 2. A telescopic rod and a support block are provided. The position of the support block can be adjusted by controlling the extension and retraction of the telescopic rod through components such as a rotating shaft, thereby controlling the minimum distance between the first heating roller and the second heating roller to ensure stable fabric processing during the operation of the equipment.

[0015] 3. An axis roller is provided, and its position can be raised and lowered to adjust the position. When the position of the axis roller changes, the wrap angle between the fabric bypassing the axis roller and the first heating roller or the second heating roller changes, thereby changing the heating time of the fabric. Furthermore, the height of the axis roller is adjusted in real time through the temperature of the first heating roller and the second heating roller, thereby controlling the heating time and ensuring the quality of the fabric.

[0016] 4. An air pipe and a conveying mechanism are provided. Under the blowing pressure of the wind sent out by the air pipe, the tension of the film material is controlled to ensure that there is sufficient friction between the film material and the conveying mechanism to ensure that it can be conveyed. In this case, the wind pressure and the conveying mechanism can also spread the film material flat to avoid the problem of wrinkles. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0020] like Figures 1 to 5As shown, a high-temperature hot-pressing laminating device includes a frame 1, the frame 1 includes two plates, and a plurality of conveying rollers are arranged between the two plates, a first heating roller 7 and a second heating roller 9 are arranged side by side inside the frame 1, the first heating roller 7 and the second heating roller 9 are provided with electric heating units, and heat is generated when electricity is turned on to melt the film on the fabric, and the second heating roller 9 is located below the first heating roller 7, and a support frame 10, the middle part of the support frame 10 is rotatably connected to the frame 1, and the end of the second heating roller 9 is rotatably engaged with one side of the upper part of the support frame 10, the support frame 10 includes T-shaped pieces on both sides and crossbeams between the T-shaped pieces, and during the rotation of the support frame 10, the position of the second heating roller 9 is driven to change, that is, the distance between the first heating roller 7 and the second heating roller 9 changes.

[0021] The frame 1 is fixedly connected to the inside with a cylinder 3. Two cylinders 3 are provided and located on both sides of the frame 1. The output end of the cylinder 3 extending upward is rotatably connected to one side of the support frame 10. When the cylinder 3 works, the output end thereof extends or retracts, that is, the support frame 10 is deflected, thereby adjusting the position of the second heating roller 9.

[0022] A shaft roller 8 is set on one side of the first heating roller 7 and the second heating roller 9 for lifting, that is, a linear motion pair is set on both sides of the frame 1, which is not limited to the use of pneumatic cylinders and electric cylinders. Its output end cooperates with the shaft roller 8. When the linear motion pair is in action, the shaft roller 8 is lifted and lowered, and the fabric is bypassed from above the shaft roller 8. When the position of the shaft roller 8 changes, the wrap angle between the fabric and the first heating roller 7 or the second heating roller 9 changes, thereby controlling the heating time of the fabric.

[0023] Two groups of unwinding mechanisms 4 and conveying mechanisms 6 are arranged inside the frame 1. The unwinding mechanism 4 is used to unwind the film material. At the same time, the unwinding mechanism 4 includes an unwinding shaft and a preset motor at the end of the unwinding shaft. When the motor is powered on, the film material on the unwinding shaft is unwound. An air pipe 5 is arranged between the unwinding mechanism 4 and the conveying mechanism 6. One end of the air pipe 5 is connected to an air pump through a pipeline. When the air pump works, gas is input into the air pipe 5. A through hole is opened downward on the side wall of the air pipe 5, and the input gas is finally sent out from the through hole. After the film material is released from the unwinding mechanism 4, it needs to bypass the conveying mechanism 6 to ensure that the conveying mechanism 6 can stably transport the film material. The gas sent out from the air pipe 5 blows toward the film material. Under wind pressure, the film material and the conveying mechanism 6 are in close contact, that is, the tension of the film material is controlled. In addition, the conveying mechanism 6 and the wind pressure also play a role in leveling the film material to ensure the quality of the fabric after hot-melt connection.

[0024] The side wall of the frame 1 is fixedly connected with a shell 13, and two shells 13 are also provided. A telescopic rod 14 is extended from one end of the shell 13, and the end of the telescopic rod 14 is fixedly connected with a support block 12. The support block 12 is opposite to the side rod preset at the lower part of the support frame 10. When the side rod and the support block 12 are in contact, the rotation of the support frame 10 in one direction is restricted, that is, the distance between the first heating roller 7 and the second heating roller 9 is restricted, thereby avoiding the problem of serious over-pressure of the film material or insufficient hot pressing.

[0025] A worm gear is provided inside the housing 13, and a rotating shaft 11 is fixedly connected to the middle of the worm gear. By rotating the rotating shaft 11, the telescopic rod 14 is extended and retracted through the transmission of the worm gear, and the position of the support block 12 is changed. At this time, the rotatable angle range of the support rod 10 is changed, thereby adjusting the minimum distance between the first heating roller 7 and the second heating roller 9, which is suitable for processing fabrics of different thicknesses.

[0026] The conveying mechanism 6 includes a rod 61, and the film material passes around the rod 61. The rod 61 is surrounded by a number of cylindrical parts, which greatly reduces the contact area between the rod 61 and the film material. Sliding blocks 65 are provided at both ends of the rod 61. A vertical slide rail is fixedly connected to the inner wall of the frame 1, and the sliding block 65 is slidably fitted on the slide rail to achieve the up and down adjustment of the conveying mechanism 6. A driving motor 67 is fixedly connected to one of the sliding blocks 65, and a belt 66 is provided at the output end of the driving motor 67 and the end of the rod 61. Furthermore, pulleys are fixedly connected at the end of the frame 61 and the output end of the driving motor 67, and the belt 66 is sleeved on the pulley. The driving motor 67 is started to drive the rotation of the rod 61.

[0027] A fixed block 63 is provided below the sliding block 65, and the fixed block 63 is fixedly connected to the inner wall of the frame 1. A screw 62 is inserted into the fixed block 63, and the end of the screw 62 cooperates with the sliding block 65, that is, the sliding block 65 is supported and fixed by the screw 62. A turning handle 64 is provided on the fixed block 63, and a worm gear is provided between the turning handle 64 and the screw 62. Specifically, the screw 62 passes through the worm gear and is threadedly connected thereto. By rotating the turning handle 64, with the help of the transmission of the worm gear, the screw 61 is pulled, and then the height of the rod 61 is changed.

[0028] Transmission boxes 2 are provided at both ends of the frame 1. The transmission box 2 is provided with components such as a motor and an air pump. For example, the internal motor drives the rotation of the first heating tube 7 through transmission components such as gears.
