DETAILED DESCRIPTION

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0017] like Figures 1 to 2 The three-side sealed envelope bag production equipment shown is characterized in that it includes: multiple brackets 1, a placement slot 2 is provided above each of the brackets 1, a first heat-resistant plate 3 is symmetrically installed in one of the placement slots 2, a conveyor belt 4 is provided on one of the brackets 1, a support part 5 is provided in another of the placement slots 2, a double-sided edge sealing part 6 and a single-sided edge sealing part 7 are provided above each of the brackets 1, a feeding part 8 is provided on the right side of another of the brackets 1, and a cutting part 9 is provided on the right side of another of the brackets 1.

[0018] The above structure is a three-side sealed envelope bag production equipment, which, when in operation, conveys the envelope bag rolls arranged in the upper and lower layers to one of the said supports 1 through an external conveying device, so that the envelope bag rolls arranged in the upper and lower layers are conveyed at intervals with the conveyor belt 4. When conveyed to the bottom of the double-sided edge sealing part 6, the double-sided edge sealing part heats and seals the two sides of the envelope bag rolls arranged in the upper and lower layers, and then the envelope bag roll continues to be conveyed to the single-sided edge sealing part 7. The single-sided edge sealing part 7 can heat and seal one side of the envelope bag roll, so that the envelope bag roll forms a three-side sealed state. At this time, the envelope bag roll continues to move to the cutting part 9 through the feeding part 8, so that the cutting part 9 cuts the heat-sealed envelope bag roll into envelope bags. Compared with the existing technology, it can automatically heat-seal the longitudinal sides and the transverse side of the envelope bag, and at the same time, it can shear and shape the heat-sealed envelope bag.

[0019] like Figure 2As shown, in some embodiments of the present invention, the support portion 5 includes a placement rack 51 placed in another placement slot 2, and multiple installation slots 52 are spaced apart on the placement rack 51, and multiple second heat-resistant plates 53 are installed and fixed in each of the installation slots 52.

[0020] The double-sided edge sealing part 6 includes a first movable frame 61 arranged above the conveyor belt 4, and fixed grooves 62 are provided on the front and rear sides of the first movable frame 61. A first hot pressing device 63 is fixed on each of the fixed grooves 62. A first hydraulic cylinder 64 is symmetrically fixed on the front and rear sides of one of the brackets 1, and the output end of each of the first hydraulic cylinders 64 is connected to the first movable frame 61.

[0021] The above structure is a three-side sealed envelope bag production equipment. When it is in operation, the first hydraulic cylinders 64 drive the first movable frame 61 to move downward, so that the first movable frame 61 drives the first hot pressing devices 63 thereon to move downward. The first hot pressing devices 63 are connected to an external power supply to drive heating. The first hot pressing devices 63 are pressed on both sides of the envelope bag roll and cooperate with the first heat-resistant plate 3 to heat-seal both sides of the envelope bag roll.

[0022] like Figure 2 As shown, in some embodiments of the present invention, the single-sided edge sealing portion 7 includes a plurality of second movable frames 71 arranged above each second heat-resistant plate 53, and a first hot pressing device 72 is installed and fixed on each second movable frame 71, and a guide column 73 is fixed on the front and rear sides of each second movable frame 71, and a plurality of plug-in ears 74 are provided on the front and rear sides of another said bracket 1, and each said guide column 73 is movably plugged into the adjacent said plug-in ear 74, and a spring 75 is fixedly connected between each said guide column 73 and the adjacent said plug-in ear 74, and a plurality of second hydraulic cylinders 76 are fixed on the front and rear sides of another said bracket 1, and each second hydraulic cylinder 76 is connected to the lower end of the adjacent said guide column 73.

[0023] The above structure is a three-side sealed envelope bag production equipment. When it is in operation, every two second hydraulic cylinders 76 drive the adjacent second movable frame 71 to move downward, so that the second movable frame 71 drives the second hot pressing device 72 to move downward, and the second hot pressing device 72 presses the envelope bag roll against the second heat-resistant plate 53. The second hot pressing device 72 and the external power supply drive heating, so that the second hot pressing device 72 cooperates with the second heat-resistant plate 53 to heat-seal one side of the envelope bag roll, so that the envelope bag roll is in a three-side sealed state.

[0024] like Figure 2As shown, in some embodiments of the present invention, the feeding portion 8 includes an extension plate 81 symmetrically arranged on the right side of another of the brackets 1, and a feeding roller 82 is movably sleeved on each of the extension plates 81 at intervals, and a spur gear 83 is fixed to the sleeve end on the rear side of each of the feeding rollers 82, and a synchronous belt 84 is sleeved and connected to each of the spur gears 83, and a motor 85 is fixed on the rear side of another of the brackets 1, and the output end of the motor 85 is fixedly connected to one of the spur gears 83.

[0025] The three-side-sealed envelope bag production equipment of the above structure, when in operation, drives one of the spur gears 83 to rotate through the motor 85, so that one of the spur gears 83 drives the remaining spur gears 83 to rotate through the synchronous belt, and when each of the spur gears 83 rotates, it drives each feed roller 82 to rotate. The feed roller 82 is set above the placement rack 51, and the envelope bag roll transported to the placement rack 51 by the conveying equipment is transported to the cutting part 9 through each feed roller 82.

[0026] like Figure 2 As shown, in some embodiments of the present invention, the cutting portion 9 includes a knife groove 91 arranged on the right side of the placement rack 51, a knife seat 92 is fixed in the knife groove 91, guide ears 93 are fixed on the front and back sides of the right side of the other bracket 1, a guide rod 94 is inserted on each of the guide ears 93, a cutting knife 95 is connected and fixed between each of the guide rods 94, a push rod motor 96 is fixed on the front and back sides of the other bracket 1, a guide rail 97 is fixed on the front and back sides of the other bracket 1, a slider 98 is movably inserted in each of the guide rails 97, and a connecting rod 99 is connected between each of the sliders 98 and the lower end of the adjacent guide rod 94.

[0027] The above structure is a three-side sealed envelope bag production equipment. When it is in operation, the output end of the push rod motor 96 drives the slider 98 to move along the guide rail 97, so that the slider 98 drives the connecting rod 99 to swing. At this time, the guide rod 94 of the connecting rod 99 moves downward along the guide ear 93. When each guide rod 94 moves, it drives the cutting knife 95 to move downward, so that the cutting knife 95 cuts the envelope bag roll after the three sides are heat-sealed, so that the envelope bag roll is cut into envelope bags. When cutting, the cutting knife 95 cooperates with the knife seat 92 fixed in the knife groove 91 to cut.

[0028] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for illustrative purposes. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention.
