Description

Technical Field

[0001] This utility model relates to the field of fabric packaging technology, and in particular to an extra-wide fabric packaging machine. Background Technology

[0002] The fabric packaging machine is used to transport packaged rolls of fabric to the front of the machine's inlet via a feeding conveyor belt. The fabric is then wrapped with PE film. During the vacuuming process, a negative pressure is created at the vacuuming device via an external vacuum tube, which causes the film to vacuum-package the fabric.

[0003] By comparing a nonwoven fabric finished product packaging machine with patent publication number CN220764946U, it can be seen that in this solution, the nonwoven fabric finished product roll is clamped by transmission rollers a and b and pressure rollers, which can ensure that the nonwoven fabric finished product roll will not shake during packaging and also reduce the generation of air bubbles. However, when the film wraps the nonwoven fabric finished product roll, there will be a certain gap between the two when the film is applied to the surface of the nonwoven fabric finished product roll. This may cause the film to wrinkle, which not only affects the appearance of the packaging, but also causes the nonwoven fabric finished product roll to be pulled during transportation, resulting in tearing at the heat-sealed joint of the film, thus reducing the quality of the packaging. Utility Model Content

[0004] The purpose of this invention is to provide an extra-wide fabric packaging machine in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] An extra-wide fabric packaging machine includes a base plate, a packaging mechanism located on the rear side of the base plate, and a wrapping mechanism for wrapping an entire roll of fabric, the wrapping mechanism being located on the front side of the base plate;

[0007] The wrapping mechanism includes a wrapping structure for wrapping the entire roll of fabric and a feeding structure for feeding the entire roll of fabric.

A front support plate is rotatably installed between the two fixed plates. A telescopic cylinder is rotatably installed between the front support plate and the fixed plates. A flattening structure is provided on the front side of the pressing plate for flattening and tightening the packaging film when wrapping the whole roll of fabric.

[0010] Preferred: The flattening structure includes a rotating frame rotatably disposed on the lower front side of the pressing plate. A torsion spring is connected between the rotating end of the rotating frame and the pressing plate. The bottom end of the rotating frame is tilted forward. A flattening roller is rotatably mounted on the bottom end of the rotating frame. A fixing rod is provided below the rotating frame on the lower side.

[0013] Preferably, the surface of the flattening roller is made of a smooth material.

[0014] Preferably, the front support plate is made of rubber.

[0015] Compared with existing technologies, the beneficial effects are as follows:

[0016] When wrapping a roll of fabric, the wrapping structure uses a pressing mechanism to press and flatten the top and bottom sides of the packaging film forward, tightening it and ensuring a tight fit between the film and the fabric roll. This reduces gaps between the two. The packaging mechanism then performs final finishing packaging, improving the fit between the film and the fabric roll, enhancing the aesthetics of the packaging, and reducing the risk of tearing during transport.

[0030] In this embodiment, the wrapping mechanism includes a wrapping structure for wrapping the entire roll of fabric and a feeding structure for feeding the entire roll of fabric.

[0031] The feeding structure includes a front conveyor frame 201 located on the front side of the base plate 100. A front conveyor belt 203 is installed on the front conveyor frame 201. A conveyor motor 202 is installed on the rotating end of the front conveyor belt 203. The output end of the conveyor motor 202 is fixed to the rotating end of the front conveyor frame 201 via a coupling. A front support plate 204 is provided on the front side of the front conveyor frame 201. Two front hydraulic cylinders 205 are provided above the front support plate 204. A front push plate 206 is provided on the telescopic end of the two front hydraulic cylinders 205. A side hydraulic cylinder 207 is provided on one end of the front conveyor frame 201 symmetrically along the front-rear direction. A limit plate 208 is installed on the telescopic end of the side hydraulic cylinder 207.

[0032] The wrapping structure includes a connecting plate 209 located on the rear side of the front conveyor frame 201. An unwinding roller 210 is rotatably mounted on the upper end of the connecting plate 209. An unwinding motor 211 is mounted on the rotating end of the unwinding roller 210. The output end of the unwinding motor 211 is fixed to the rotating end of the unwinding roller 210 via a coupling. A partition 213 is fixed on the rear side of the connecting plate 209. A tensioning roller is rotatably mounted on the front side of the partition 213. A pressing structure for wrapping the entire roll of fabric is provided below the partition 213.

[0033] The pressing structure includes two telescopic hydraulic cylinders 214 positioned close to each other on the side of the partition 213 and the base plate 100. The two telescopic hydraulic cylinders 214 are distributed vertically. The telescopic ends of the telescopic hydraulic cylinders 214 are equipped with pressing plates 215. Heating rods 218 are provided at the inner ends of the upper and lower pressing plates 215 close to each other. A cutter 217 is slidably installed at the bottom of the upper pressing plate 215. A pressing hydraulic cylinder 216 is provided between the cutter 217 and the pressing plate 215. Two fixed plates 221 are symmetrically arranged along the front-back direction on the rear side of the pressing plate 215. A front support plate 222 is rotatably installed between the two fixed plates 221. The front support plate 222 is made of rubber. A telescopic cylinder 223 is rotatably installed between the front support plate 222 and the fixed plates 221. A flattening structure is provided on the front side of the pressing plate 215 for flattening and tightening the packaging film when wrapping the whole roll of fabric.

[0034] The flattening structure includes a rotating frame 219 rotatably mounted on the lower front side of the pressing plate 215. A torsion spring connects the rotating end of the rotating frame 219 to the pressing plate 215. The bottom end of the rotating frame 219 is tilted forward, and a flattening roller 220 is rotatably mounted on the bottom end of the rotating frame 219. The surface of the flattening roller 220 is made of a smooth material. A fixing rod is provided below the rotating frame 219 on the lower side. A packaging film 212 is wound between the unwinding roller 210, the tensioning roller, and the fixing rod. When the wrapping structure wraps the entire roll of fabric, the pressing structure presses and flattens the upper and lower sides of the packaging film forward, causing the packaging film to tighten forward and adhere tightly to the surface of the entire roll of fabric, reducing the gap between the two. Then, the packaging mechanism performs final fine packaging of the entire roll of fabric, thereby improving the adhesion between the packaging film and the entire roll of fabric, increasing the aesthetics of the packaging, and reducing the tearing phenomenon during the conveying of the entire roll of fabric.

[0035] In this embodiment: the packaging mechanism includes a rear conveyor frame 301 disposed on the rear side of the base plate 100. Drive rollers 302 are rotatably mounted on both the front and rear sides of the rear conveyor frame 301. A feeding motor 315 is mounted on the rotating end of the drive rollers 302. The feeding motor 315 is fixed to the rotating end of the drive rollers 302 via a coupling. Multiple rear conveyor belts 303 are provided between two drive rollers 302. A lifting plate 304 is provided between two adjacent rear conveyor belts 303. A lifting cylinder 305 is provided between the lifting plate 304 and the base plate 100. Multiple rear conveyor belts distributed front and rear are fixed to the upper end of the lifting plate 304. The pallet 306 and the rear pallet 306 are made of silicone. The rear conveyor frame 301 is symmetrically provided with two suction chambers 307 in the front-to-back direction. A suction fan 308 is rotatably installed inside the suction chamber 307. A heating chamber 309 is provided on the rear side of the suction chamber 307. A blower 310 is installed inside the heating chamber 309. A heating pipe 311 is provided on the side of the blower 310 near the rear conveyor frame 301. A rear support plate 312 is provided on the rear side of the heating chamber 309. A rear push plate 314 is slidably installed in the rear support plate 312. A pusher hydraulic cylinder 313 is installed between the rear push plate 314 and the rear support plate 312.

[0036] Working principle: First, the conveyor motor 202 is started to drive the front conveyor belt 203 to rotate, conveying the entire roll of fabric to the rear of the front push plate 206. Then, the front hydraulic cylinder 205 is driven to push the front push plate 206 backward, pushing the entire roll of fabric above the front support plate 222. At the same time as pushing, the packaging film 212 just wraps the surface of the entire roll of fabric. Then, the telescopic hydraulic cylinders 214 on the upper and lower sides are driven to move the pressing plates 215 on the upper and lower sides closer together, pressing and heat-sealing the front side of the packaging film 212. While moving, the flattening roller 220 on the front side will move first, causing the flattening roller 220 to come into contact with the packaging film 212. Then, using the torsion springs set between the rotating ends of the two rotating frames 219 and the pressing plate 215, the rotating frames 219 will drive the flattening roller 220 to move forward as the pressing plate 215 continues to move, pressing and flattening the upper and lower sides of the packaging film 212 forward, tightening the packaging film 212 forward, and making the packaging film 212 tightly adhere to the surface of the whole roll of fabric, reducing the gap between the two.

[0037] Then, the heating rod 218 at the bottom of the pressing plate 215 heats the bottom end of the pressing plate 215, so that the upper and lower pressing plates 215 heat-melt the upper and lower sides of the packaging film 212, so that the upper and lower sides of the packaging film 212 are bonded together. Then, the hydraulic cylinder 216 is driven to drive the cutter 217 to press down and cut the bonded part of the packaging film 212, so that the packaging film 212 is completely wrapped on the surface of the whole roll of fabric. Then, the telescopic cylinder 223 is driven to drive the rear end of the front support plate 222 to rotate downward, so that the whole roll of fabric is tilted backward onto the rear conveyor belt 303 above the rear conveyor frame 301. The feeding motor 315 is driven to drive the rear conveyor belt 303 to rotate and transport the whole roll of fabric backward.

[0038] When the entire roll of fabric moves to the suction chamber 307, the driving lifting cylinder 305 moves the lifting plate 304 upward, which in turn moves the rear support plate 306 upward, lifting the entire roll of fabric. The suction fan 308 inside the suction chamber 307 sucks away the air between the entire roll of fabric and the packaging film 212, creating a vacuum between them. Then, the entire roll of fabric continues to move backward to the heating chamber 309, where it is lifted upward. The heating tube 311 inside the heating chamber 309 heats the fabric, and the blower 310 blows the heat to the end of the entire roll of fabric, heating it. The entire roll of fabric continues to move backward to the rear support plate 312, where the driving pushing hydraulic cylinder 313 moves the rear push plate 314 towards the end of the entire roll of fabric, pressing the heated end and sealing it. Finally, the packaging operation of the entire roll of fabric is completed.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
