[0001] This utility model relates to the field of sealing machine technology, and in particular to a sealing machine for pickled vegetable buns. Background Technology
[0002] Vacuum packaging machines are used when packaging pickled vegetable bags. The pickled vegetable bags are placed on the packaging machine, and the open end of the bag is locked in place by the heat seal strip. The machine cover is closed, and the air inside the machine is evacuated by a pump on one side of the cover. Then, the opening of the bag is sealed by heating the heat seal strip.
[0003] When using a vacuum packaging machine to package pickled vegetables, the liquid from the pickling process is easily spilled onto the worktable because the machine's interior surface is flat. This contaminates the machine's working environment, and the accumulated liquid is difficult to clean, causing inconvenience when using the vacuum packaging sealing machine. Summary of the Invention
[0004] The purpose of this invention is to solve the problem that, because the internal surface of the packaging machine is flat, the liquid from pickling vegetables is easily spilled onto the worktable during the sealing process, polluting the working environment of the vacuum packaging machine. Furthermore, the liquid accumulates inside the packaging machine and is difficult to clean, causing inconvenience when using the vacuum packaging sealing machine. Therefore, this invention provides a sealing machine for pickled vegetable bags.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a sealing machine for pickled vegetable bags, comprising a machine body, an air extraction pump installed inside the machine body, heat sealing plates on both sides of the top of the machine body, a pressure rod rotatably mounted on one side of the heat sealing plate, a cover plate rotatably mounted on the top of the machine body, an air extraction hole for extraction opened on the inner wall of the cover plate, an air extraction pipe installed on one side of the cover plate, the other end of the air extraction pipe being connected to the pump inside the machine body, and a drainage device installed inside the machine body to facilitate the discharge of liquid leaked from the pickled vegetable bags when sealing them with the sealing machine.
[0006] The effect achieved by the above components is as follows: When sealing a pickled vegetable bag with a sealing machine, place the pickled vegetable bag flat on the top of the machine body, so that the open end of the pickled vegetable bag rests against the heat sealing plate. Push the pressure rod on one side of the heat sealing plate to rotate and press the open end of the pickled vegetable bag. Then, hold the handle on the top of the cover plate and pull the cover plate to rotate and close the top of the machine body. Control the operation of the pump inside the machine body through the control panel on one side of the machine body. The air at the top of the machine body is extracted through the air extraction pipe to make the top of the machine body a vacuum state. After a period of time, control the operation of the heating element inside the heat sealing plate through the control panel to heat and seal the pickled vegetable bag. Then, push the cover plate to move and open the cover plate. Pull the pressure rod to rotate and take out the pickled vegetable bag.
[0007] Preferably, the draining device includes a circular tube, one end of which is fixed to one side of the machine body. A V-shaped groove is formed at the top of the machine body. Several baffles are fixedly connected to the top of the inner wall of the V-shaped groove, and the baffles are linearly distributed at the top of the V-shaped groove. A draining groove is formed at the bottom of the inner wall of the V-shaped groove. The bottom of the draining groove is inclined, and the lower end faces the circular tube. One end of the circular tube is connected to the interior of the draining groove. A piston rod is slidably connected to the inner wall of the circular tube. Two springs are provided at the end of the piston rod away from the circular tube. The two ends of the two springs are fixedly connected to one side of the piston rod and one side of the circular tube, respectively. A drain pipe is fixedly connected to the bottom of the circular tube.
[0008] The effect achieved by the above components is as follows: By setting up a drain pipe, when using the sealing machine, the pickled vegetable bag is placed on the baffle surface at the top of the machine body. If the liquid inside the pickled vegetable bag leaks, it will enter the interior of the V-shaped groove, then flow along the inner wall of the inclined surface of the V-shaped groove into the interior of the drain pipe, and then through the drain pipe into the interior of the round tube. After the sealing machine is used, one end of the piston rod can be held and pulled to slide the piston rod away from the round tube and compress the spring, so that the end of the piston rod inside the round tube passes over the top of the drain pipe. Then the liquid inside the round tube will be discharged through the drain pipe. After the liquid is discharged, the piston rod is released and the spring returns to its original state, which will pull the piston rod to slide in the original direction, and the top of the drain pipe is sealed by the piston rod.
[0009] Preferably, a rubber sealing block is fixedly connected to one end of the piston rod, and the sealing block slides on the inner wall of the circular tube.
[0010] The effect achieved by the above components is that by setting a rubber sealing block, the inside of the round tube can be further sealed, thereby improving the sealing effect of the piston rod on the inside of the round tube.
[0011] Preferably, one end of the piston rod is fixedly connected to two round rods, and the ends of the round rods away from the piston rod slide on one side of the outer surface of the round tube.
[0012] The effect achieved by the above components is that when the piston rod is pulled, the round rod will slide on the outer surface of the round tube. The round rod can further limit the angle of the piston rod inside the round tube, so that the piston rod will not deviate and the movement will be smoother.
[0013] Preferably, the diameter of the round rod is smaller than the inner diameter of the spring, and the two round rods are located inside the two springs respectively.
[0014] The effect achieved by the above components is that when the piston rod moves and causes the spring to deform, the spring will move on the outside of the round rod. The round rod can reinforce the internal shape of the spring, making the spring less prone to twisting when compressed.
[0015] Preferably, the piston rod is fixedly connected to two protruding rods at the end away from the sealing block, with the two protruding rods located on the upper and lower sides of the piston rod respectively.
[0016] The effect achieved by the above components is that the two protruding rods on the outer surface of the piston rod can be used to more easily pull the piston rod to move its position.
[0017] Preferably, a filter device is provided at the bottom end of the drain pipe. The filter device includes a filter frame, a filter screen is provided on the surface of the filter frame, a locking block is fixedly connected to the top of the filter frame, and groove blocks are fixedly connected to both sides of the drain pipe. The outer surface of the groove blocks is provided with through grooves.
[0018] The effect achieved by the above components is as follows: before the liquid is discharged through the drain pipe of the drain device, the top of the clip connected to the filter frame can be inserted into the through groove on the surface of the groove on both sides of the drain pipe, so that the clip and the filter frame are fixed at the bottom of the drain pipe. The filter screen on the filter frame can filter impurities such as pickled vegetable leaves carried in the liquid. After the filter frame is removed, it is convenient to separate the liquid and the pickled vegetable leaves on the filter screen, thus improving the practicality of the drain device.
[0019] Preferably, a plurality of protruding strips are fixedly connected to both sides of the top of the card block, and the protruding strips are made of rubber.
[0020] The effect achieved by the above components is that by setting the rubber protrusions, the friction between the insert block and the inner wall of the slot block can be increased, making the insert block less likely to fall off accidentally.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0022] In this invention, by setting up a drainage device and opening a V-shaped groove at the top of the machine body, the liquid leaking out when the pickled vegetable bag is sealed enters the interior of the V-shaped groove and flows into the interior of the circular pipe along the drainage groove. This prevents the liquid leaking out of the pickled vegetable bag from accumulating at the top of the machine body when using the sealing machine. Moving the position of the piston rod allows the liquid to be discharged through the drainage pipe, making it convenient to clean up the leaked liquid and improving the convenience and cleanliness of using the sealing machine.

Detailed Implementation
[0029] Example 1, as shown in Figures 1-2, includes a sealing machine for pickled vegetable bags, comprising a body 1. The body 1 contains an internal pump for extracting air. Heat-sealing plates 4 are located on both sides of the top of the body 1. A pressure rod 5 is rotatably mounted on one side of each heat-sealing plate 4. A cover plate 6 is rotatably mounted on the top of the body 1. An air extraction hole is provided on the inner wall of the cover plate 6. An air extraction pipe 7 is located on one side of the cover plate 6, and the other end of the pipe 7 is connected to the pump inside the body 1. The body 1 contains a drainage device 2 to facilitate the discharge of liquid leaked from the pickled vegetable bags during sealing. When sealing the pickled vegetable bags using the sealing machine, the liquid is... The bag is placed flat on top of the machine body 1, with the open end of the pickled vegetable bag resting against the heat sealing plate 4. The pressure rod 5 on one side of the heat sealing plate 4 is pushed to rotate and press down the open end of the pickled vegetable bag. Then, the handle at the top of the cover plate 6 is held and pulled to rotate the cover plate 6 to close the top of the machine body 1. The pump inside the machine body 1 is controlled by the control panel on one side of the machine body 1. The air at the top of the machine body 1 is extracted through the air extraction pipe 7 to create a vacuum at the top of the machine body 1. After a period of time, the heating element inside the heat sealing plate 4 is controlled by the control panel to heat and seal the pickled vegetable bag. Then, the cover plate 6 is pushed to move and open the cover plate 6. The pressure rod 5 is pulled to rotate and the pickled vegetable bag is taken out.
[0030] Referring to Figures 1-4, in this embodiment: the draining device 2 includes a circular tube 24, one end of which is fixed to one side of the machine body 1. A V-shaped groove 21 is formed at the top of the machine body 1. Several baffles 22 are fixedly connected to the top of the inner wall of the V-shaped groove 21. The baffles 22 are linearly distributed at the top of the V-shaped groove 21. A draining groove 23 is formed at the bottom of the inner wall of the V-shaped groove 21. The bottom of the inner wall of the draining groove 23 is inclined, and the lower end faces the circular tube 24. One end of the circular tube 24 is connected to the interior of the draining groove 23. A piston rod 25 is slidably connected to the inner wall of the circular tube 24. Two springs 26 are provided at the end of the piston rod 25 away from the circular tube 24. The two ends of the two springs 26 are fixedly connected to one side of the piston rod 25 and one side of the circular tube 24, respectively. A drain pipe 27 is fixedly connected to the bottom end of the circular tube 24. By setting the drain pipe 27, when using the sealing machine, if the pickled vegetable bag is placed on the surface of the baffle 22 at the top of the machine body 1, and if the liquid inside the pickled vegetable bag leaks, it will enter the interior of the V-shaped groove 21 and then flow down the V-shaped groove 21. The liquid enters the interior of the drainage trough 23 through the inclined inner wall, and then enters the interior of the circular tube 24 through the drainage trough 23. After the sealing machine is used, one end of the piston rod 25 can be held and pulled to slide the piston rod 25 away from the circular tube 24 and compress the spring 26, so that the end of the piston rod 25 inside the circular tube 24 passes over the top of the drainage pipe 27. Then the liquid inside the circular tube 24 will be discharged through the drainage pipe 27. After the drainage is completed, release the piston rod 25 and the spring 26 will return to its original state, which will pull the piston rod 25 back to the original direction. The piston rod 25 is used to seal the top of the drain pipe 27. By setting the drain device 2 and opening a V-shaped groove 21 at the top of the machine body 1, the liquid leaking out when the pickled vegetable bag is sealed enters the interior of the V-shaped groove 21 and flows into the interior of the round pipe 24 along the drain groove 23. This prevents the liquid leaking out of the pickled vegetable bag from accumulating at the top of the machine body 1 when using the sealing machine. Moving the position of the piston rod 25 allows the liquid to be discharged through the drain pipe 27, making it convenient to clean up the leaked liquid and improving the convenience and cleanliness of the sealing machine during use.
[0031] Referring to Figures 2-4, in this embodiment: a rubber sealing block 28 is fixedly connected to one end of the piston rod 25. The sealing block 28 slides on the inner wall of the round tube 24. By setting the rubber sealing block 28, the inside of the round tube 24 can be further sealed, improving the sealing effect of the piston rod 25 on the inside of the round tube 24. Two round rods 29 are fixedly connected to one end of the piston rod 25. The end of the round rod 29 away from the piston rod 25 slides on the outer surface of the round tube 24. When the piston rod 25 is pulled, the round rod 29 will slide on the outer surface of the round tube 24. The round rod 29 can further limit the angle of the piston rod 25 inside the round tube 24, so that the angle of the piston rod 25 will not be deflected and the movement is smoother.
[0032] Referring to Figures 2-4, in this embodiment: the diameter of the round rod 29 is smaller than the inner diameter of the spring 26. The two round rods 29 are located inside the two springs 26 respectively. When the piston rod 25 moves and causes the spring 26 to deform, the spring 26 will move outside the round rod 29. The round rod 29 can reinforce the internal shape of the spring 26, making it less likely to twist when the spring 26 is compressed. Two protrusions 210 are fixedly connected to the end of the piston rod 25 away from the sealing block 28. The two protrusions 210 are located on the upper and lower sides of the piston rod 25 respectively. Holding the two protrusions 210 on the outer surface of the piston rod 25 makes it easier to pull the piston rod 25 to move its position.
[0033] Referring to Figures 1, 3, 4, and 5, in this embodiment: a filter device 3 is provided at the bottom end of the drain pipe 27. The filter device 3 includes a filter frame 33, with a filter screen on the surface of the filter frame 33. A locking block 32 is fixedly connected to the top of the filter frame 33. Grooves 31 are fixedly connected to both sides of the drain pipe 27. A through groove is formed on the outer surface of the groove 31. Before the liquid is discharged through the drain pipe 27 of the drain device 2, the top of the locking block 32 connected to the filter frame 33 can be inserted into the through groove on the surface of the groove 31 on both sides of the drain pipe 27, so that the locking block 32 and the filter frame 33... Fixed at the bottom of the drain pipe 27, the filter screen on the filter frame 33 can filter impurities such as pickled vegetable leaves carried in the liquid. After removing the filter frame 33, it is convenient to separate the liquid and the pickled vegetable leaves on the filter screen of the filter frame 33, which improves the practicality of the drain device 2. Several protrusions 34 are fixedly connected to the top two sides of the locking block 32. The protrusions 34 are made of rubber. By setting the protrusions 34 of rubber material, the friction between the locking block 32 and the inner wall of the groove on the surface of the groove block 31 can be increased, making the locking block 32 less likely to fall off accidentally.
[0034] Working principle: When sealing a pickled vegetable bag using a sealing machine, place the bag flat on top of the machine body 1, with the open end resting against the heat sealing plate 4. Push the pressure rod 5 on one side of the heat sealing plate 4 to rotate, pressing down on the open end of the bag. Then, pull the handle at the top of the cover plate 6 to rotate and seal the top of the machine body 1. The pump inside the machine body 1 is controlled via the control panel on one side, drawing air out through the suction pipe 7 to create a vacuum at the top of the machine body 1. After a period of time, the heating element inside the heat sealing plate 4 is controlled via the control panel to heat and seal the bag. Then, push the cover plate 6 to open it, and pull the pressure rod 5 to rotate and remove the bag. If liquid leaks from inside the bag, it will enter the V-shaped groove 21, then flow along the inclined inner wall of the V-shaped groove 21 into the drainage groove 23, and finally drain through the drainage groove 23. After the sealing machine is used, the top of the locking block 32 connected to the filter screen frame 33 can be inserted into the through groove on the surface of the groove block 31 on both sides of the drain pipe 27, so that the locking block 32 and the filter screen frame 33 are fixed at the bottom of the drain pipe 27. Then, hold one end of the piston rod 25 and pull the piston rod 25 away from the round tube 24 and compress the spring 26, so that the end of the piston rod 25 inside the round tube 24 passes over the top of the drain pipe 27. Then the liquid inside the round tube 24 will be discharged along the drain pipe 27. The impurities such as pickled vegetable leaves carried in the liquid can be filtered through the filter screen on the filter screen frame 33. After the liquid is discharged, release the piston rod 25 and the spring 26 will return to its original state and pull the piston rod 25 to slide in the original direction. The top of the drain pipe 27 is sealed by the piston rod 25. The filter screen frame 33 is removed and the liquid and the pickled vegetable leaves on the filter screen on the surface of the filter screen frame 33 are processed separately.
