Description

Technical Field

[0001] The utility model relates to the field of vacuum packaging machines, in particular to a bacon vacuum packaging machine. Background Art

[0002] The vacuum packaging machine can automatically extract the air in the packaging bag and complete the sealing process after reaching a predetermined vacuum degree. It can also be filled with nitrogen or other mixed gases to complete the sealing process. Vacuum packaging machines are often used in the food industry because after vacuum packaging, the food can resist oxidation and achieve the purpose of long-term preservation. In the process of bacon production, in order to increase the shelf life of bacon, the bacon is generally put into bags and vacuum packaged using a vacuum packaging machine.

[0003] The current vacuum packaging machines are mainly divided into two steps of vacuuming and sealing when vacuum packaging food. The sealing is mainly performed by heating the packaging bags with sealing heating strips. The sealing heating strips of the current vacuum packaging machines are respectively arranged on both sides of the top of the supporting platform with a fixed installation spacing, resulting in that only two rows of packaging bags to be sealed can be placed during packaging. When the size of the packaging bags is small, the space in the middle of the supporting platform cannot be effectively utilized, resulting in a relatively low vacuum packaging efficiency of the entire vacuum packaging machine.

Rotating rods 104 are symmetrically connected to both sides of the bearing platform 101, and a top cover 103 is rotatably connected between the rotating rods 104 on both sides. The setting of the top cover 103 can drive the top cover 103 to rotate when rotating, so that the top cover 103 can cover one side of the top of the bearing platform 101. A sealing ring 108 is fixedly connected to the bottom of the top cover 103. The setting of the sealing ring 108 can abut against the top of the bearing platform 101 when the top cover 103 covers one side of the top of the bearing platform 101, thereby realizing the sealing of the gap between the bearing platform 101 and the top cover 103.

[0027] A stepper motor 105 is fixedly connected to one side of the carrier 101, and a worm 106 is fixedly connected to the output end of the stepper motor 105. A set of rotating rods 104 are fixedly connected to a worm wheel 107 on the side away from the carrier 101. The worm wheel 107 is meshed with the worm 106. The stepper motor 105 is used to drive the worm 106 and the worm wheel 107 to rotate when starting the work, and the worm wheel 107 can drive the corresponding rotating rod 104 to rotate when rotating, so as to adjust the top cover 103. The lower sealing mechanism 2 includes L-shaped limit grooves 201 symmetrically opened on both sides of the top of the carrier 101. A lower sealing heating strip 206 is provided above the carrier 101. The lower sealing heating strip 206 is used to heat the packaging bag placed on the top thereof when powered on.

[0028] Both ends of the lower sealing heating strip 206 are fixedly connected with L-shaped insulating limit blocks 202 that are compatible with the L-shaped limit groove 201, so that the L-shaped insulating limit block 202 can be inserted into the inside of the L-shaped limit groove 201. One side of the L-shaped insulating limit block 202 away from the lower sealing heating strip 206 is rotatably connected with a J-shaped pressure rod 203. The setting of the J-shaped pressure rod 203 can press the packaging bag tightly, thereby reducing the probability of the packaging bag warping and causing poor sealing effect of the packaging bag. The outer wall of the J-shaped pressure rod 203 is fixedly connected with a connecting ring 204, and a torsion spring 205 is fixedly connected between the connecting ring 204 and the L-shaped insulating limit block 202. The setting of the torsion spring 205 can use its own elastic effect to drive the J-shaped pressure rod 203 to rotate, so that the J-shaped pressure rod 203 can press the packaging bag tightly between the support platform 101 and the J-shaped pressure rod 203. A lower copper rod 208 is fixedly connected to the inside of each group of L-shaped limit grooves 201, and a conductive block 207 abutting against the lower copper rod 208 is fixedly connected to the side of the L-shaped insulating limit block 202 close to the lower copper rod 208. The conductive blocks 207 on both sides are electrically connected to the two ends of the lower sealing heating strip 206, so that when the lower copper rod 208 is energized, the lower sealing heating strip 206 is energized and works after conduction through the conductive blocks 207.

The outer side of the adjusting screw 211 is threadedly connected to the connecting rod 210, and the connecting rod 210 is fixedly connected to the bearing platform 101. When the adjusting screw 211 rotates, it can drive the limit plate 209 to slide inside the L-shaped limit groove 201 on one side, so that the limit plate 209 can push the L-shaped insulating limit block 202 and the conductive block 207 to move to one side of the lower copper rod 208, so that the conductive block 207 and the lower copper rod 208 are tightly pressed against each other.

[0030] The side of the connecting rod 210 away from the limit plate 209 is symmetrically fixedly connected with a reinforcing rib plate 212, and each group of reinforcing rib plates 212 is fixedly connected to the bearing platform 101. The setting of the reinforcing rib plates 212 can ensure the stability of the connection between the connecting rod 210 and the bearing platform 101. The upper sealing mechanism 3 includes a hydraulic rod 302 that penetrates and is fixed inside the top cover 103. The output end of the hydraulic rod 302 is fixedly connected to the sealing cover 301. The setting of the hydraulic rod 302 is used to drive the sealing cover 301 to move up and down when starting the work. The inside of the sealing cover 301 is symmetrically fixedly connected with an upper copper rod 303, and one side of the two groups of upper copper rods 303 is abutted with a copper block 308. The bottom of the two groups of copper blocks 308 is fixedly connected with an upper sealing heating strip 304. When the upper copper rod 303 is energized, the conduction of the groove 309 makes the upper sealing heating strip 304 energized and work.

[0031] A groove 309 is provided on one side wall of the two groups of copper blocks 308, and the groove 309 abuts against the outer wall of the upper copper rod 303.

A mounting opening 305 is provided on one side of the sealing cover 301, and a limiting screw 307 is passed through the interior of the mounting opening 305. One end of the limiting screw 307 is fixedly connected to a copper block 308 on one side, and the outer side of the limiting screw 307 is threadedly connected to a limiting nut 306, and the limiting nut 306 abuts against the outer wall of the sealing cover 301. When the limiting nut 306 is screwed until it is tightly abutted against the sealing cover 301, the copper block 308 can be tightly abutted against the outer wall of the upper copper rod 303 to meet the need for electrical conduction between the upper copper rod 303 and the copper block 308.
