Description

Technical Field

[0001] This invention relates to the field of packaging equipment technology, specifically to a probiotic powder packaging equipment with four-sided sealing function. Background Technology

[0002] Probiotics are a class of live microorganisms that are beneficial to the host. They are a general term for live beneficial microorganisms that colonize the intestines and reproductive system of humans or animals, produce specific health benefits, and thus improve the host's microecological balance and play a beneficial role.

[0003] For example, a probiotic powder packaging device with publication number CN113148266A, through the setting of sealing and encapsulation mechanisms, facilitates four-sided sealing of the packaging, effectively improving the packaging efficiency of the equipment, simplifying the equipment, reducing the intervention of electrical control equipment, and achieving more stable and faster packaging. However, in actual use, after the probiotic powder is filled and packaged, it is quite sensitive to oxygen. If the powder bag leaks, it will cause the powder to become inactive, reducing the product efficacy. In order to ensure the airtightness of the probiotic powder after packaging, it is necessary to conduct an airtightness test on the packaged probiotic powder bag. In the production process, an additional airtightness test is required after the powder is packaged, which will consume a certain amount of time and affect the production efficiency of probiotic powder. At the same time, the airtightness test cannot be performed immediately after the probiotic powder is packaged. If the powder bag leaks, the powder will come into contact with the air, which will reduce the activity of the powder. As a result, the powder in the leaked powder bag cannot be refilled, resulting in waste. There are certain defects in its use.

[0004] Therefore, we propose a probiotic powder packaging device with four-sided sealing function to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide a probiotic powder packaging device with four-sided sealing function, so as to solve the problems mentioned in the background art, which require an additional testing step to check the airtightness after packaging the probiotic powder in the production process, which consumes a certain amount of time and affects the production efficiency of probiotic powder. At the same time, the airtightness cannot be checked immediately after packaging the probiotic powder. If the powder bag leaks, the powder will come into contact with the air, which will reduce the activity of the powder and cause the powder in the leaked powder bag to be unable to be refilled, resulting in waste.

[0028] By adopting the above technical solution, the sleeve can be rotated half a revolution for every one revolution of the connecting shaft.

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows: the probiotic powder packaging equipment with four-side sealing function enables continuous four-side sealing of probiotic powder. When sealing the top and bottom sides of the powder bag, the packaging film can be cut immediately after sealing, saving cutting steps. When continuously sealing the powder, cutting time can be saved and packaging efficiency can be improved. At the same time, after sealing both sides of the powder bag, the sealing performance of the powder bag can be tested immediately, reducing operation steps and ensuring the continuity of the powder packaging. Furthermore, since the sealing performance test is performed immediately after packaging, any leaked powder will not immediately come into contact with the air. If a powder bag leaks, the powder in the leaked powder bag can be recovered and repackaged in a timely manner, avoiding waste.

[0030] 1. When packaging probiotic powder, the packaging film is placed on two rotating rollers. The packaging film passes through the guide groove and the two drive rollers. The drive rollers rotate and pull the packaging film to move. At the same time, a heating structure is set on one side of the drive rollers. The two drive rollers roll and heat-seal both sides of the packaging film. Then, an electric push rod drives the front movable frame to move, so that the two movable frames come closer together. This causes the two sealing strips to squeeze the packaging film, achieving heat sealing of the bottom edge of the packaging film. The probiotic powder is then quantitatively filled through the filling tube. During continuous operation, the two sealing strips can seal the bottom and top of the upper and lower powder bags. When sealing the top and bottom of the powder bag, the two movable frames come closer together. The movement of the rear movable frame can drive the sleeve to rotate half a revolution, causing the box body to rotate half a revolution. The packaged powder bag can then... The powder bag falls directly into the box. It enters the baffle and the extrusion plate along the inclined side of the baffle. At this time, one end of the push rod abuts against the inclined side of the arc block. Continuous operation causes the movable frame to move away from each other, causing the sleeve to reset and rotate. At this time, the solenoid valve inside the air inlet pipe closes. When the box resets and rotates, the push rod moves along the inclined side of the arc block, causing the first piston to slide in the first cylinder. The first cylinder and the second cylinder are both provided with vent holes on one side of the push rod and the moving rod. After the first piston moves, the air inside the first cylinder is pushed into the second cylinder through the connecting pipe, which can drive the second piston to move, which can drive the moving rod to move. Then, through the L-shaped frame and the connecting frame, the movable plate slides on the support rod and stretches the telescopic spring, which can push the extrusion plate to move. The extrusion plate moves to extrude the powder bag.

[0031] The powder bag is squeezed between the extrusion plate and the baffle. After the movable frame resets, the box rotates to the bottom, at which point the next powder bag is filled. During this time, the extrusion plate remains stationary. Observe whether the pressure sensor reading continuously decreases. If the reading continuously decreases, it indicates that the powder bag is leaking. After the powder bag leaks, the extrusion plate is no longer tightly attached to the powder bag. The leaking powder bag can be removed in time, and the bacterial powder in the leaking powder bag can be recovered and refilled. If the reading does not change significantly, the next powder bag needs to be sealed. Continue to drive the box to rotate upward. When the box just starts to rotate, the solenoid valve on the air inlet pipe opens, and the air inside the second cylinder is discharged. The return spring then drives... The squeezing plate resets, releasing the powder bag. Qualified powder bags fall automatically. When the box rotates to the top and resets again, the solenoid valve closes. The solenoid valve is controlled by a controller to open and close at regular intervals during the continuous packaging of the mushroom powder. This allows for immediate testing of the powder bag's seal after both sides are sealed, reducing operational steps and ensuring the continuity of the mushroom powder packaging. Furthermore, because the seal test is performed immediately after packaging, any leaked mushroom powder will not immediately come into contact with air. If a leak occurs, the mushroom powder in the leaked bag can be promptly recovered and repackaged, avoiding waste.

[0032] 2. When sealing the bottom and top of the powder pack, the movable end of the electric push rod is retracted. Under the action of the support spring, the front movable frame can be moved. During the movement of the movable frame, the toothed plate on the positioning frame moves. After the toothed plate on the positioning frame moves, it can drive the toothed plate on the limit frame to move through the meshing of the rotating gear, so that the two movable frames can approach each other at the same time, and thus the two sealing strips can move at the same time to fit together, which facilitates sealing the powder pack. After sealing the pack, the movable end of the electric push rod is retracted again, and the two sealing strips abut against the movable frame and stop moving, which can drive the connecting plate to move. The connecting plate drives the sliding plate to move, so that the cutting blade can cut off the connection between the two packs, which can continuously seal the four sides of the probiotic powder. When sealing the top and bottom sides of the powder pack, the packaging film can be cut off immediately after sealing, saving the cutting steps.

[0033] 3. When sealing the bottom and top of the powder bag, the rear movable frame moves, driving the rack to move. After the rack moves, it can drive the first bevel gear to rotate through the meshing driven gear. The rotation of the first bevel gear and the second bevel gear can drive the connecting shaft to rotate. After the two sealing strips are attached, they drive the driven gear to rotate one revolution. The transmission ratio of the first bevel gear and the second bevel gear is 1:1, which allows the connecting shaft to rotate one revolution. Then, the first transmission wheel drives the second transmission wheel to rotate. The first transmission wheel and the second transmission wheel can also be driven by a sprocket. The transmission ratio of the first transmission wheel and the second transmission wheel is 2:1, which allows the connecting shaft to rotate one revolution and drive the sleeve to rotate half a revolution. This allows the box to rotate through the sealing work of the bag. When packaging the bacterial powder, there is no need to add a testing step, ensuring the continuity of packaging.

The two ends of the return spring 220 are fixedly connected to the first cylindrical body 216 and the first piston 218, respectively. A connecting pipe 222 is connected through the bottom of the first cylindrical body 216. The end of the connecting pipe 222 away from the first cylindrical body 216 is connected through the second cylindrical body 217. An arc-shaped block 221 is fixedly installed on the end of the fixing rod 205 away from the chassis 1. The top of the push rod 219 abuts against the arc-shaped edge of the arc-shaped block 221.

[0053] The second cylinder 217 is internally connected to a second piston 223, and a moving rod 224 is slidably connected to one side of the second piston 223. The moving rod 224 is slidably connected to the second cylinder 217. Meanwhile, an air inlet pipe 225 is connected through the side of the second cylinder 217 away from the first cylinder 216. A solenoid valve is installed inside the air inlet pipe 225. An L-shaped frame 226 is fixedly installed at the end of the moving rod 224 away from the second piston 223. A connecting frame 227 is fixedly installed at one end of the L-shaped frame 226. Meanwhile, one end of the connecting frame 227 is fixedly connected to the movable plate 213.

[0054] Two movable frames 108 are symmetrically arranged below the two mounting plates 102. An edge sealing strip 110 is fixedly installed on the side of the two movable frames 108 that are close to each other. Electric push rods 109 are symmetrically slidably connected inside the two movable frames 108. At the same time, one end of the two electric push rods 109 is fixedly connected to the chassis 1.

One end of the limiting rods 112 is fixedly connected to the chassis 1.

[0055] Example 1: As Figures 1-6As shown, when packaging probiotic powder, the packaging film is placed on two rotating rollers 105. The packaging film passes through the guide groove 106 and the two drive rollers 107. The drive rollers 107 rotate and pull the packaging film to move. At the same time, a heating structure is set on one side of the drive rollers 107. The two drive rollers 107 can heat-seal both sides of the packaging film by rolling. Then, the electric push rod 109 drives the front movable frame 108 to move, so that the two movable frames 108 move closer at the same time, so that the two sealing strips 110 squeeze the package. The film filling process allows for heat sealing of the bottom edge of the packaging film. The powder is then quantitatively filled through the filling tube 103. During continuous operation, the two sealing strips 110 seal the bottom and top of the upper and lower powder bags. When sealing the top and bottom of the powder bags, the two movable frames 108 move closer together. The movement of the rear movable frame 108 causes the sleeve 202 to rotate half a revolution, resulting in a half-revolution of the box body 204. The packaged powder bag then falls precisely into the box body 204, following the oblique angle of the baffle 207. After entering the baffle 207 and the extrusion plate 211, one end of the push rod 219 abuts against the inclined side of the arc-shaped block 221, and continuous operation causes the movable frame 108 to move away from each other, causing the sleeve 202 to reset and rotate. At this time, the solenoid valve inside the air inlet pipe 225 closes, and when the box body 204 resets and rotates, the push rod 219 moves on the inclined side of the arc-shaped block 221, causing the first piston 218 to slide in the first cylinder 216. The first cylinder 216 and the second cylinder 217 are located between the push rod 219 and the movable frame 202. Ventilation holes are provided on one side of rod 224. After the first piston 218 moves, the air inside the first cylinder 216 is pushed into the second cylinder 217 through the connecting pipe 222, which can drive the second piston 223 to move, which can drive the moving rod 224 to move. Then, through the L-shaped frame 226 and the connecting frame 227, the movable plate 213 slides on the support rod 214 and stretches the telescopic spring 215, which can push the extrusion plate 211 to move. The extrusion plate 211 moves to extrude the powder bag.

[0056] The powder bag is squeezed between the extrusion plate 211 and the baffle 207. After the movable frame 108 resets, the box 204 rotates to the bottom. At this time, the next powder bag is filled. During this process, the extrusion plate 211 is stationary. The reading of the pressure sensor 209 is observed to see if it continuously decreases. If the reading continuously decreases, it indicates that the powder bag is leaking. After the powder bag leaks, the extrusion plate 211 is no longer tightly attached to the powder bag. The leaking powder bag can be removed in time, and the bacterial powder in the leaking powder bag can be recovered and refilled. If the reading does not change significantly, the next powder bag needs to be sealed. The box 204 continues to rotate upward. When the box 204 just starts to rotate, the solenoid valve on the air inlet pipe 225 opens, and the second cylinder 217 is filled. When the air is expelled, the return spring 220 drives the squeezing plate 211 to reset, which can release the powder bag. Qualified powder bags can fall automatically. When the box body 204 rotates to the top and resets again, the solenoid valve closes. By setting a controller to control the solenoid valve to open and close at timed intervals during the continuous packaging process of the bacterial powder, the airtightness of the powder bag can be checked immediately after sealing both sides of the powder bag, reducing the number of operation steps and ensuring the continuity of bacterial powder packaging. At the same time, since the airtightness of the powder bag is checked immediately after packaging, any leaked bacterial powder will not immediately come into contact with the air. If a powder bag leaks, the bacterial powder in the leaked powder bag can be recovered and repackaged in time to avoid waste.

[0057] Two electric push rods 109 are fixedly mounted with connecting plates 113 at their movable ends. A support spring 114 is sleeved on the outside of the movable end of the electric push rod 109 on one side of the connecting plate 113. The two ends of the support spring 114 are fixedly connected to the connecting plate 113 and the front movable frame 108, respectively. Meanwhile, a sliding plate 115 is fixedly mounted on the side of the connecting plate 113 near the front movable frame 108. The sliding plate 115 is slidably connected to the front movable frame 108 and the front edge sealing strip 110. A cutting blade 116 is fixedly mounted on one side of the sliding plate 115. A cutting groove is opened on the front side of the rear edge sealing strip 110.

[0058] On the front of the chassis 1, above the two electric push rods 109, there are symmetrical support frames 117, and the two support frames 117 are rotatably connected to a rotating gear 118. On the top of the front movable frame 108, there are symmetrical positioning frames 119, and on the top of the rear movable frame 108, there are symmetrical limit frames 120. On the side of the positioning frame 119 and the limit frame 120 near the rotating gear 118, there are fixed tooth plates 121, and the tooth plates 121 are meshed with the rotating gear 118.

[0059] Example 2: Figure 3 , Figure 7 and Figure 9As shown, when sealing the bottom and top of the powder bag, the movable end of the electric push rod 109 retracts. Under the action of the support spring 114, the front movable frame 108 can move. During the movement of the movable frame 108, the upper toothed plate 121 of the positioning frame 119 moves. After the upper toothed plate 121 of the positioning frame 119 moves, it can drive the upper toothed plate 121 of the limiting frame 120 to move through the meshing rotating gear 118. This allows the two movable frames 108 to approach each other at the same time, thereby allowing the two sealing strips 110 to move simultaneously for bonding, which facilitates the sealing of the powder bag. After sealing the package, the movable end of the electric push rod 109 retracts, and the two sealing strips 110 abut against the movable frame 108 and stop moving. This allows the connecting plate 113 to move, which in turn moves the sliding plate 115, allowing the cutting blade 116 to cut off the connection between the two packages. This enables continuous sealing of the four sides of the probiotic powder. Furthermore, when sealing the top and bottom sides of the powder package, the packaging film can be cut immediately after sealing, saving the cutting step.

[0060] A rack 122 is fixedly installed at the bottom of the rear movable frame 108, and mounting brackets 123 are symmetrically installed on the front of the chassis 1 below the rack 122. A driven gear 124 is rotatably connected between the two mounting brackets 123. The driven gear 124 passes through one mounting bracket 123 via a rotating shaft and is fixedly installed with a first bevel gear 125. A crossbeam 126 is fixedly installed on the front of the chassis 1 below the first bevel gear 125.

[0061] A connecting shaft 127 is rotatably connected to one side of the inner side of the crossbar 126, and a second bevel gear 128 is fixedly installed at one end of the connecting shaft 127. The second bevel gear 128 meshes with the first bevel gear 125. Meanwhile, a first transmission wheel 129 is fixedly installed at the other end of the connecting shaft 127. A second transmission wheel 130 is fixedly installed on the outside of the sleeve 202 on one side of the support base 201, and the second transmission wheel 130 is rotatably connected to the first transmission wheel 129 via a belt.

[0062] Example 3: Figure 3 and Figure 8As shown, when sealing the bottom and top of the powder bag, the rear movable frame 108 moves, driving the rack 122 to move. After the rack 122 moves, it can drive the first bevel gear 125 to rotate through the meshing driven gear 124. The rotation of the first bevel gear 125 and the second bevel gear 128 can drive the connecting shaft 127 to rotate. After the two sealing strips 110 are attached, they drive the driven gear 124 to rotate one revolution. The transmission ratio of the first bevel gear 125 and the second bevel gear 128 is one to one, so that the connecting shaft 127 rotates. 27 can rotate one revolution, and then drive the second drive wheel 130 to rotate through the first drive wheel 129. The first drive wheel 129 and the second drive wheel 130 can also be driven by a sprocket. The transmission ratio of the first drive wheel 129 and the second drive wheel 130 is two to one, so that the rotation of the connecting shaft 127 can drive the sleeve 202 to rotate half a revolution. This allows the box body 204 to rotate through the sealing work of the packaging. When packaging the bacterial powder, no additional testing steps are needed, ensuring the continuity of packaging.

[0063] Working principle: When using this probiotic powder packaging equipment with four-side sealing function, firstly, according to... Figures 1-9As shown, when packaging probiotic powder, the packaging film is placed on two rotating rollers 105. The packaging film passes through the guide groove 106 and the two drive rollers 107. The drive rollers 107 rotate and pull the packaging film to move. At the same time, a heating structure is set on one side of the drive rollers 107. The two drive rollers 107 can heat-seal both sides of the packaging film by rolling. Then, the electric push rod 109 drives the front movable frame 108 to move, so that the two movable frames 108 move closer at the same time, so that the two sealing strips 110 squeeze the package. The film filling process allows for heat sealing of the bottom edge of the packaging film. The powder is then quantitatively filled through the filling tube 103. During continuous operation, the two sealing strips 110 seal the bottom and top of the upper and lower powder bags. When sealing the top and bottom of the powder bags, the two movable frames 108 move closer together. The movement of the rear movable frame 108 causes the sleeve 202 to rotate half a revolution, resulting in a half-revolution of the box body 204. The packaged powder bag then falls precisely into the box body 204, following the oblique angle of the baffle 207. After entering the baffle 207 and the extrusion plate 211, one end of the push rod 219 abuts against the inclined side of the arc-shaped block 221, and continuous operation causes the movable frame 108 to move away from each other, causing the sleeve 202 to reset and rotate. At this time, the solenoid valve inside the air inlet pipe 225 closes, and when the box body 204 resets and rotates, the push rod 219 moves on the inclined side of the arc-shaped block 221, causing the first piston 218 to slide in the first cylinder 216. The first cylinder 216 and the second cylinder 217 are located between the push rod 219 and the movable frame 202. Ventilation holes are provided on one side of rod 224. After the first piston 218 moves, the air inside the first cylinder 216 is pushed into the second cylinder 217 through the connecting pipe 222, which can drive the second piston 223 to move, which can drive the moving rod 224 to move. Then, through the L-shaped frame 226 and the connecting frame 227, the movable plate 213 slides on the support rod 214 and stretches the telescopic spring 215, which can push the extrusion plate 211 to move. The extrusion plate 211 moves to extrude the powder bag.

[0064] The powder bag is squeezed between the extrusion plate 211 and the baffle 207. After the movable frame 108 resets, the box 204 rotates to the bottom. At this time, the next powder bag is filled. During this time, the extrusion plate 211 is stationary. By observing whether the reading of the pressure sensor 209 is continuously decreasing, if the reading is continuously decreasing, it indicates that the powder bag is leaking. After the powder bag leaks, the extrusion plate 211 is no longer tightly attached to the powder bag. The leaking powder bag can be removed in time, and the bacterial powder in the leaking powder bag can be recovered and refilled. If the reading does not change significantly, the next powder bag needs to be sealed. The box 204 continues to rotate upward. When the box 204 just starts to rotate, the solenoid valve on the air inlet pipe 225 opens, and the air inside the second cylinder 217 is discharged. The reset spring 220 drives the extrusion plate 211 to reset, and the powder bag can be released. The qualified powder bag can fall automatically. When the box 204 rotates to the top and resets again, the solenoid valve closes. The solenoid valve is opened and closed at timed intervals during the continuous packaging of bacterial powder by setting a controller.

[0065] When sealing the bottom and top of the powder bag, the movable end of the electric push rod 109 retracts. Under the action of the support spring 114, the front movable frame 108 moves. During the movement of the movable frame 108, the upper toothed plate 121 of the positioning frame 119 moves. After the upper toothed plate 121 of the positioning frame 119 moves, it can drive the upper toothed plate 121 of the limiting frame 120 to move through the meshing rotating gear 118, so that the two movable frames 108 can approach each other at the same time, and thus the two sealing strips 110 can move at the same time to fit together, which facilitates sealing the powder bag. After sealing the bag, the movable end of the electric push rod 109 continues to retract, and the two sealing strips 110 abut against the movable frame 108 and no longer move, so that the connecting plate 113 can move, and the connecting plate 113 can drive the sliding plate 115 to move, so that the cutting blade 116 can cut off the connection between the two sealed bags, allowing the connection to be completed. The probiotic powder is then sealed on all four sides. When sealing the bottom and top of the powder pack, the rear movable frame 108 moves, causing the rack 122 to move. After the rack 122 moves, it can drive the first bevel gear 125 to rotate through the meshing driven gear 124. The rotation of the first bevel gear 125 and the second bevel gear 128 can drive the connecting shaft 127 to rotate. After the two sealing strips 110 are in contact, they drive the driven gear 124 to rotate one revolution. The transmission ratio of the first bevel gear 125 and the second bevel gear 128 is 1:1, which allows the connecting shaft 127 to rotate one revolution. Then, the first transmission wheel 129 drives the second transmission wheel 130 to rotate. The first transmission wheel 129 and the second transmission wheel 130 can also be driven by a sprocket. The transmission ratio of the first transmission wheel 129 and the second transmission wheel 130 is 2:1, which allows the sleeve 202 to rotate half a revolution when the connecting shaft 127 rotates one revolution.
