[0019] Referring to Figures 1-2 As shown in the drawings, the wearable rubber vacuum packaging device provided by the present application comprises a cabinet, which is a rectangular frame structure composed of a support frame and sheet metal. Four universal wheels with brakes are mounted on the bottom of the cabinet, and meanwhile, height-adjustable support feet are mounted on the four corners of the bottom of the cabinet. The cabinet comprises a side cabinet 101 and a working cabinet 102. The side cabinet 101 is located on one side of the working cabinet 102, and the side cabinet 101 and the working cabinet 102 are fixedly connected.

[0020] Referring to Figures 3-4 As shown in the drawings, a transmission assembly is arranged at one end of the working cabinet 102. The transmission assembly comprises a transmission frame 201, which is in a rectangular frame structure and is fixedly connected to the upper surface of the working cabinet 102 and one side of the side cabinet 101. A rectangular opening is formed in the upper surface of the transmission frame 201 and extends along the length direction of the transmission frame 201. Transmission rollers 202 are mounted at both ends of the transmission frame 201 and can rotate on the transmission frame 201. A transmission belt 203 is sleeved between the two transmission rollers 202. The transmission belt 203 is located at the rectangular opening of the transmission frame 201. An inlet 204 is fixedly installed at one end of the transmission frame 201 and is located at the initial end of the transmission assembly.

[0021] A bag supplying assembly is arranged below the transmission assembly and is mounted on the side cabinet 101. The bag supplying assembly can provide plastic paper required for packaging. The bag supplying assembly comprises two mounting plates 301. One of the mounting plates 301 is fixedly installed on the side cabinet 101. The other mounting plate 301 is located on one side of the side cabinet 101 and is distributed in parallel with the side cabinet 101. A bag placing roller 302 is mounted between the two support plates and can rotate therebetween. Plastic paper is wound on the bag placing roller 302.

[0022] A circular hole is formed on the side wall of the side cabinet 101, and the bag placing roller 302 and the conveying roller 202 both pass through the circular hole and extend into the side cabinet 101. One end of the bag placing roller 302 is provided with a main sprocket 303, and one end of the conveying roller 202 is provided with a driven sprocket 304. The main sprocket 303 and the driven sprocket 304 are provided with a first chain 305 therebetween.

A first motor 306 is installed in the side cabinet 101, and the output end of the first motor 306 is in butt joint with the bag placing roller 302. When the first motor 306 drives the bag placing roller 302 to rotate, the conveying roller 202 can be driven to rotate synchronously through the first chain transmission structure. When the bag placing roller 302 rotates, the plastic paper wound on the surface thereof can be continuously placed out, and at the same time, the conveying roller 202 rotates synchronously under the drive of the driven sprocket 304, so as to form traction on the plastic paper placed out, so that the plastic paper is stably conveyed to the packaging station according to the preset path, realizing continuous and synchronous supply and transmission of the plastic paper.

[0023] In addition, two bag pressing rollers 307 are arranged above the bag placing roller 302, and the two bag pressing rollers 307 are rotatably installed on the side cabinet 101. The two bag pressing rollers 307 are parallel and have a certain spacing. The plastic paper passes through the gap between the two bag pressing rollers 307, and the rotation of the bag pressing rollers 307 forms clamping and flattening effects on the plastic paper, so as to avoid wrinkles or deviation of the plastic paper during transmission. A guide roller 308 is arranged on one side of the two bag pressing rollers 307. The guide roller 308 is rotatably installed on the side cabinet 101, and the guide roller 308 is located below the feeding port 204.

The air cylinder can drive the base plate 401 to move along the height direction of the side cabinet 101.

[0025] The sleeve 404 is fixedly installed on the substrate 401 and is perpendicular to the substrate 401. One end of the sleeve 404 is provided with a mounting frame 405, and the mounting frame 405 is located above the conveying belt 203. Two transmission shafts 406 are vertically and downwardly installed on the mounting frame 405, the two transmission shafts 406 are parallel to each other, and the two transmission shafts 406 can rotate on the mounting frame 405. The two transmission shafts 406 are located above the conveying belt 203 and are parallel to each other. A sleeve shaft 407 is installed in the sleeve 404, and the sleeve shaft 407 can rotate in the sleeve 404. A main bevel gear 408 is installed at one end of the sleeve shaft 407, and a slave bevel gear 409 is installed at the top end of one of the transmission shafts 406. The main bevel gear 408 is engaged with the slave bevel gear 409. A roller 412 is installed below each transmission shaft 406, and the roller 412 can rotate synchronously with the transmission shaft 406.

[0026] A fixed plate 413 is fixedly installed at the middle position of the substrate 401, the fixed plate 413 is located between the two sleeves 404, and the fixed plate 413 is perpendicular to the substrate 401. A transverse sealing frame 414 is installed at one end of the fixed plate 413, and two transverse sealing plates 415 are installed below the transverse sealing frame 414, the two transverse sealing plates 415 are located above the conveying belt 203 and between the two rollers 412.

[0027] A straight slot is formed in the side wall of the side cabinet 101, and the straight slot extends along the height direction of the side wall. One end of the two sleeve shafts 407 passes through the straight slot and extends into the side cabinet 101. When the substrate 401 moves vertically, the sleeve shaft 407 can move vertically along the straight slot. One end of the two sleeve shafts 407 extends into the side cabinet 101.

[0029] The two edges of the plastic paper are pinched, and the plastic paper passes between the two rollers 412 on one side of the feeding port 204. Since the two rollers 412 are respectively installed below the corresponding transmission shaft 406, and the transmission shaft 406 can drive the roller 412 to rotate, the plastic paper will be clamped and synchronously conveyed forward when passing through the gap between the rollers 412. Under the conveying of the rollers 412, the plastic paper passes between the two transverse sealing plates 415. The transverse sealing plate 415 seals and connects the two edges of the pinched plastic paper by a preset heating and pressurizing process, so that the two edges of the originally separated plastic paper are firmly combined. After the rollers 412 pinch and the transverse sealing plate 415 seals the edges, the U-shaped plastic paper becomes a semi-closed packaging bag with a cylindrical structure. The circumferential side edge of the packaging bag forms a complete cylinder wall due to the sealing connection, and only the two ends in the transmission direction remain open. After the side edge is sealed, the plastic paper continues to move under the action of the transmission, and finally passes between the two rollers 412 away from the feeding port 204. The rollers 412 on this side also clamp and convey the plastic paper.
