Description

Technical Field

[0001] This utility model belongs to the field of packaging engineering technology, and in particular relates to a vacuum heat sealing machine for ton bags. Background Technology

[0002] According to the published patent CN116101573A, a ton-bag type heat sealing machine includes an inner cavity; a vacuum pump; an outer frame; a heat sealing assembly; and a conveyor. The inner cavity is slidably disposed inside the outer frame and slides up and down within the outer frame. The conveyor is disposed at the bottom of the outer frame and corresponds vertically to the inner cavity. The heat sealing assembly performs heat sealing of the ton bags. This machine has the advantages of simple structure and convenient adjustment, making it more suitable for meeting factory production needs. However, it still has the following shortcomings:

[0003] The above equipment achieves the effect of simple and convenient adjustment. However, during the vacuuming process, the air inside the ton bag is extracted, and the pressure inside the bag decreases. If the bag opening is not stable, the bag may slip or deform due to changes in internal pressure, which may lead to the risk of the bag loosening or material leakage. Therefore, we provide a ton bag vacuum heat sealing machine. Utility Model Content

[0004] The purpose of this utility model is to provide a vacuum heat sealing machine for ton bags. Through the positioning mechanism and the heat sealing mechanism, the above-mentioned equipment achieves the effect of simple and convenient adjustment after completion. However, during the vacuuming process, the air inside the ton bag is extracted, and the pressure inside the bag decreases. If the bag opening is not stable, the bag may slip or deform due to changes in internal pressure, which may lead to the risk of the bag loosening or material leakage.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a vacuum heat sealing machine for ton bags, including a main frame, an air pump fixedly connected to the top outer wall of the main frame, an air extraction pipe fixedly connected to the bottom output end of the air pump, an exhaust pipe fixedly connected to the bottom output end of the air pump, and a positioning mechanism provided on the inner wall of the main frame.

[0007] The positioning mechanism includes a rotating shaft, the outer wall of which is rotatably connected to the inner wall of the main frame. A worm gear is fixedly connected to the outer wall of the rotating shaft near the air pump. A worm is rotatably connected to the inner wall of the main frame near the air pump, and the outer wall of the worm meshes with the outer wall of the worm gear. A gear is fixedly connected to the outer wall of the rotating shaft away from the air pump. Several slide rails are fixedly connected to the inner wall of the main frame near the worm gear. Limiting rods are slidably connected to the inner walls of the slide rails. A rack is fixedly connected to the outer wall of the limiting rod away from the slide rail. A heat sealing mechanism is provided on the inner wall of the main frame.

[0008] Furthermore, the outer wall of the rack meshes with the outer wall of the gear, and a connecting frame is fixedly connected to the outer wall of the rack near the worm gear.

[0009] Furthermore, a positioning plate is fixedly connected to the outer wall of the end of the connecting frame away from the worm gear, and the inner wall of the positioning plate is provided with several anti-slip grooves.

[0010] Furthermore, the heat sealing mechanism includes a support frame, the outer wall of which is fixedly connected to the inner wall of the main frame, and a motor plate is fixedly connected to the inner wall of the main frame near the rotating shaft.

[0011] Furthermore, a controller is fixedly connected to the outer wall of the motor plate near the rotating shaft, and a motor is fixedly connected to the outer wall of the motor plate near the rotating shaft.

[0012] Furthermore, the bottom output shaft of the motor is fixedly connected to a rotating shaft via a coupling. The outer wall of the rotating shaft is rotatably connected to the inner wall of the support frame.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model, by setting a positioning plate, first places the opening of the ton bag onto the rotating shaft, then rotates the worm gear, using the rotation of the gear to drive the racks at both ends to move, and uses the movement of the positioning plates at both ends to fix the ton bag on the rotating shaft. The anti-slip groove prevents the ton bag from falling off the rotating shaft, thus achieving stable positioning of the ton bag and preventing the ton bag from falling off the device during the vacuuming process.

[0017] 2. This utility model incorporates a heating plate and an air pump. The air pump extracts gas from the ton bag through a suction pipe and then discharges the extracted gas through an exhaust pipe. The heating plate is then activated and heated for a certain period of time. Finally, the motor is started by the controller, and the rotation of the heating plate heats the opening of the ton bag after it has been evacuated. This achieves both vacuum treatment of the inside of the ton bag and heat sealing of the evacuated ton bag.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

A rack 207 is fixedly connected to the outer wall of the end of the limiting rod 206 away from the slide rail 205. The outer wall of the rack 207 meshes with the outer wall of the gear 204. A connecting frame 208 is fixedly connected to the outer wall of the end of the rack 207 near the worm wheel 202. A heat sealing mechanism 3 is provided on the inner wall of the main frame 1. The rotation of the gear 204 drives the rack 207 to move, avoiding the rack 207 from affecting the rotation of the gear 204 and causing the device to jam.

[0030] A positioning plate 209 is fixedly connected to the outer wall of the connecting frame 208 away from the worm gear 202. The inner wall of the positioning plate 209 is provided with several anti-slip grooves 210. The heat sealing mechanism 3 includes a support frame 301. The outer wall of the support frame 301 is fixedly connected to the inner wall of the main frame 1. The movement of the connecting frame 208 drives the positioning plate 209 to move stably, preventing the positioning plate 209 from falling off during movement and causing the device to be unable to position the ton bag. A motor plate 302 is fixedly connected to the inner wall of the main frame 1 near the rotating shaft 201. A controller 303 is fixedly connected to the outer wall of the motor plate 302 near the rotating shaft 201.

[0032] One specific application of this embodiment is:

[0033] When the operator needs to use the equipment, first, the opening of the ton bag is placed on the rotating shaft 201. Then, the worm gear 203 is rotated, which drives the worm wheel 202 to rotate. The worm wheel 202 drives the rotating shaft 201 to rotate, which in turn drives the gear 204 to rotate. The rotation of the gear 204 drives the racks 207 at both ends to move in opposite directions. The racks 207 drive the limiting rod 206 to move in the slide rail 205. The limiting rod 206 prevents the racks 207 from falling off during movement. Next, the racks 207 drive the connecting frame 208 to move, which in turn drives the positioning plate 209 to move. The movement of the positioning plates 209 at both ends fixes the ton bag on the rotating shaft 201. The anti-slip groove 210 prevents the ton bag from falling off the rotating shaft 201. Then, the air pump 101 is started. The air pump 101 extracts the gas from the ton bag through the air extraction pipe 102 and then discharges the extracted gas through the exhaust pipe 103. After the inside of the ton bag is evacuated to a vacuum state, the heating plate 310 is started first and heated for a certain period of time. Then, the motor 304 is started through the controller 303. The motor 304 causes the rotating shaft 305 to start rotating. The rotating shaft 305 drives the gear 306 to rotate. The rotation of the gear 306 drives the gear 308 to rotate. The gear 308 drives the rotating shaft 307 to rotate. The rotation of the rotating shaft 305 and the rotating shaft 307 drives the auxiliary frames 309 at both ends to rotate. The rotation directions of the auxiliary frames 309 are opposite. The auxiliary frames 309 drive the heating plate 310 to rotate. The rotation of the heating plate 310 is used to heat seal the opening of the ton bag after the internal vacuum is achieved.
