Technical Field
[0001] This utility model relates to the field of traction conveying technology, and in particular to a chain-type lower film traction conveying device for a stretch film packaging machine. Background Technology
[0002] Stretch film vacuum packaging machines, also known as fully automatic stretch film vacuum packaging machines, are high-efficiency vacuum packaging equipment. During operation, a traction conveyor is used to pull the packaging film. Currently, the most common traction conveyor is the chain-type traction conveyor. To ensure smooth chain operation, existing chain-type traction conveyors typically require periodic lubrication of the sprockets and chains. However, most chain lubrication currently requires manual operation, consuming significant time and manpower. Therefore, this invention improves upon existing traction conveyor systems by using chain circulation to periodically lubricate the chain and sprockets. Utility Model Content
[0003] This disclosure relates to a chain-type uncoupling traction conveyor for a stretch film packaging machine. It stores lubricating oil in a lubricating oil storage tank. During the conveying of the uncoupling mold by the traction conveyor chain, the transmission action of the traction conveyor chain is converted and transmitted to the lubricating oil storage tank through the cooperation of multiple structures. This causes the lubricating oil storage tank to descend intermittently, releasing lubricating oil into the interior of the drive sprocket. The drive sprocket then uses a lubrication release hole to lubricate the traction conveyor chain, thus completing the automatic lubrication of the traction conveyor chain.
[0004] In a first aspect, this disclosure provides a chain-type film traction conveying device for a stretch film packaging machine, specifically comprising: a mounting base, with transmission bases fixedly mounted on the left and right sides of the mounting base; a drive motor fixedly mounted on the bottom front end of the transmission base; a transmission clamping groove formed on the inner side of the transmission base; conversion inclined grooves formed at the front and rear ends of the inner side of the transmission base; the conversion inclined grooves having an inclined structure, and the lowest end of the conversion inclined grooves communicating with the end of the transmission clamping groove; a transmission loosening groove formed on the rear side and both sides of the transmission base; the two ends of the transmission loosening grooves respectively connecting to the highest ends of the two conversion inclined grooves; a driven sprocket rotatably mounted on the rear top side of the transmission base; a driving sprocket rotatably mounted on the front top side of the transmission base; the bottom end of the driving sprocket connected to the output shaft of the drive motor; a lubrication release hole formed on the outer wall of the driving sprocket; and a cylindrical guide docking post fixedly mounted on the top of the driving sprocket; a guide docking hole formed on the circumferential outer wall of the guide docking post.
[0005] In at least some embodiments, a traction conveying chain is installed on the adjacent driving sprocket and driven sprocket; a clamping fastener is fixedly installed on the traction conveying chain; the clamping fastener has an L-shaped structure.
[0006] In at least some embodiments, the clamping fastener is further equipped with a clamping slider; the clamping slider has an L-shaped structure; and the bottom end of the clamping slider is fixedly installed with the interior of a cylindrical clamping and releasing slider.
[0007] In at least some embodiments, the end of the clamping and releasing sliding column is slidably mounted in a transmission groove composed of a transmission clamping groove, a conversion inclined groove, and a transmission loosening groove; a trigger slide plate is fixedly mounted on the top of the clamping and fixing member; and a cylindrical trigger sliding column is fixedly mounted on the top of the trigger slide plate.
[0008] In at least some embodiments, an L-shaped support plate is fixedly installed on the top of the transmission base; a cylindrical lubrication guide post is slidably installed on the top of the support plate; and a disc-shaped force-bearing plate is fixedly installed on the top of the lubrication guide post.
[0009] In at least some embodiments, one end of a restoring spring is embedded in the bottom of the force-bearing plate; the other end of the restoring spring is embedded in the top of the support plate; and a lubricating oil storage cylinder is fixedly installed at the bottom of the lubrication guide post.
[0010] In at least some embodiments, the front end of the lubricating oil storage cylinder is provided with an oil replenishment port; an oil replenishment cap is installed on the oil replenishment port by means of threads; a sealing stop ring is fixedly installed at the bottom of the inside of the lubricating oil storage cylinder; and the flow guiding docking column is also slidably connected to the sealing stop ring.
[0011] In at least some embodiments, a force transmission component is fixedly installed on the outer circumferential wall of the lubricating oil storage cylinder; a transition groove is provided on the outer bottom side of the force transmission component; and a force-bearing groove is provided on the inner bottom side of the force transmission component.
[0012] In at least some embodiments, the center position of the force-bearing chute is inclined; the trigger slide and trigger slide plate slide back and forth into the interior of the transition chute and the force-bearing chute following the traction conveyor chain.
[0013] In at least some embodiments, after the trigger slide column slides into the interior of the force-receiving groove, the trigger slide column will descend with the force transmission component and the lubricating oil storage cylinder using the inclined structure at the center of the force-receiving groove; after the lubricating oil storage cylinder descends, the flow guiding docking column will disengage from the sealing stop ring and insert into a deeper position in the lubricating oil storage cylinder.
[0014] This utility model provides a chain-type lower film traction conveyor for a stretch film packaging machine, which has the following advantages:
[0015] 1. Because the transmission base is provided with a transmission groove consisting of a transmission clamping groove, a conversion inclined groove and a transmission loosening groove, during the process of the traction conveyor chain carrying the clamping fixing part and the clamping sliding part circulating, the clamping sliding part will cooperate with the transmission groove under the action of the clamping and loosening conversion sliding column to automatically realize the clamping and traction of the lower film and the loosening and disengagement, so that this traction conveyor device has sufficient traction smoothness.
[0016] 2. After the clamping and fixing component follows the traction conveyor chain to a certain position, the trigger slide pin on the triggering slide plate on the clamping and fixing component will slide into the inside of the force receiving slide groove. The trigger slide pin will use the inclined structure of the force receiving slide groove to pull down the force transmission component and the lubricating oil storage cylinder. The lubricating oil storage cylinder will release the lubricating oil inside into the drive sprocket by descending. The lubricating oil will then be applied to the traction conveyor chain through the lubrication release hole on the drive sprocket. This will automatically achieve periodic lubrication of the traction conveyor chain, which is more time-saving and labor-saving than using dedicated personnel to lubricate.
[0017] 3. The number of trigger slide plates and trigger slide columns in this utility model can be selectively arranged. When frequent lubrication is required, the trigger slide plates and trigger slide columns can be arranged at multiple points. More trigger slide columns will frequently trigger the force transmission components and lubricating oil storage cylinder to release lubricating oil. Conversely, fewer trigger slide plates and trigger slide columns will reduce the lubrication frequency of this conveying device. Thus, the lubrication frequency in this utility model can be adjusted according to the user's needs, improving the applicability of this device. Attached Figure Description

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0034] Please refer to Figures 1 to 8 :
[0035] Example 1:
[0036] This utility model proposes a chain-type lower film traction conveying device for a stretch film packaging machine, comprising: a mounting base 1, with transmission bases 2 fixedly mounted on the left and right sides of the mounting base 1; a drive motor 3 fixedly mounted on the bottom front end of the transmission base 2; a transmission clamping groove 4 formed on the inner side of the transmission base 2; and conversion inclined grooves 5 formed at the front and rear ends of the inner side of the transmission base 2; the conversion inclined grooves 5 have an inclined structure, and the lowest end of the conversion inclined grooves 5 is connected to the end of the transmission clamping groove 4; the rear side and the left and right sides of the transmission base 2 are connected together... A transmission slack groove 6 is provided; both ends of the transmission slack groove 6 are respectively connected to the highest ends of two conversion inclined grooves 5; a driven sprocket 7 is rotatably mounted on the top rear side of the transmission base 2; a driving sprocket 8 is rotatably mounted on the top front side of the transmission base 2; the bottom end of the driving sprocket 8 is connected to the output shaft of the drive motor 3; a lubrication release hole 9 is provided on the outer wall of the driving sprocket 8; a cylindrical flow guide docking column 10 is fixedly mounted on the top of the driving sprocket 8; a flow guide docking hole 11 is provided on the outer circumference of the flow guide docking column 10.
[0037] By placing the packaging film on the corresponding clamping fastener 13, and then starting the drive motor 3, the drive motor 3 rotates the drive sprocket 8. The drive sprocket 8, through rotation, cooperates with the driven sprocket 7 to drive the traction conveyor chain 12. The traction conveyor chain 12 carries multiple clamping fasteners 13 and clamping sliding members 14. When the clamping and loosening transition slide column 15 on the clamping sliding member 14 slides from the inside of the transmission loosening groove 6 into the inside of the transmission clamping groove 4, the clamping and loosening transition slide column 15 will use the inclined structure of the transition sloping groove 5 to move the clamping sliding member 14 downward. The clamping sliding member 14, through its descent, cooperates with the clamping fastener 13 to clamp the film. Then, as the clamping fasteners 13 and clamping sliding members 14 continue to follow the traction conveyor chain 12, the clamping fasteners 13 and clamping sliding members 14 will traction and convey the clamped film, making it easy to pull the film to the packaging station for use.
[0038] In Example 2, based on Example 1, a traction conveying chain 12 is installed on the adjacent driving sprocket 8 and driven sprocket 7; a clamping fastener 13 is fixedly installed on the traction conveying chain 12; the clamping fastener 13 has an L-shaped structure; a clamping sliding member 14 is also installed on the clamping fastener 13; the clamping sliding member 14 has an L-shaped structure; the bottom end of the clamping sliding member 14 is fixedly installed inside the cylindrical clamping and loosening sliding column 15; the end of the clamping and loosening sliding column 15 is slidably installed in the transmission groove composed of the transmission clamping groove 4, the conversion inclined groove 5, and the transmission loosening groove 6; a trigger slide plate 16 is fixedly installed on the top of the clamping fastener 13; a cylindrical trigger slide column 17 is fixedly installed on the top of the trigger slide plate 16; an L-shaped support plate 18 is also fixedly installed on the top of the transmission base 2; a cylindrical lubrication guide column 19 is slidably installed on the top of the support plate 18; a disc-shaped force-bearing baffle 20 is fixedly installed on the top of the lubrication guide column 19.
[0039] The trigger slide plate 16 is fixedly connected to the clamping fastener 13 by bolts and has the characteristic of being detachable. Therefore, the number of trigger slide plates 16 and trigger slide pins 17 can be arranged according to the user's needs. The more trigger slide plates 16 and trigger slide pins 17 are arranged, the more frequently the device lubricates the traction conveyor chain 12. The fewer trigger slide plates 16 and trigger slide pins 17 are arranged, the fewer times the device lubricates the traction conveyor chain 12.
[0040] In Example 3, based on Example 2, one end of a restoring spring 21 is embedded in the bottom of the force-bearing baffle 20; the other end of the restoring spring 21 is embedded in the top of the support plate 18; a lubricating oil storage cylinder 22 is fixedly installed at the bottom of the lubrication guide post 19; an oil replenishment port 23 is provided at the front end of the lubricating oil storage cylinder 22; an oil replenishment cap is threaded onto the oil replenishment port 23; a sealing stop ring 24 is fixedly installed at the bottom inside the lubricating oil storage cylinder 22; the flow guide docking post 10 is also slidably connected to the sealing stop ring 24; a force transmission component 25 is fixedly installed on the outer circumference of the lubricating oil storage cylinder 22; the bottom of the force transmission component 25 is... A transition groove 26 is provided on the side; a force transmission component 25 has a force-bearing groove 27 on its bottom inner side; the force-bearing groove 27 has an inclined structure at its central position; the trigger slide 17 and the trigger slide plate 16 will slide back and forth into the transition groove 26 and the force-bearing groove 27 along with the traction conveyor chain 12; after the trigger slide 17 slides into the force-bearing groove 27, the trigger slide 17 will use the inclined structure at the central position of the force-bearing groove 27 to bring the force transmission component 25 and the lubricating oil storage cylinder 22 down; after the lubricating oil storage cylinder 22 descends, the guide docking column 10 will disengage from the sealing stop ring 24 and insert into a deeper position in the lubricating oil storage cylinder 22.
[0041] After the trigger slide plate 16 and trigger slide column 17 on the clamping fixture 13 move to a certain position, the trigger slide column 17 will slide unimpeded through the transition slide groove 26 and slide into the inclined position of the force receiving slide groove 27. The force receiving slide groove 27 uses its own inclined structure to convert the horizontal sliding force of the trigger slide column 17 into a vertical sliding force and provide it to the force transmission component 25. The force transmission component 25 is forced to move the lubricating oil storage cylinder 22 downward. After moving, the flow guiding docking column 10 will be inserted deeper into the lubricating oil storage cylinder 22, so that the flow guiding docking hole 11 is out of the range of the sealing stop ring 24. The lubricating oil inside the lubricating oil storage cylinder 22 enters the interior of the drive sprocket 8 through the flow guiding docking hole 11, and then the lubricating oil is injected onto the traction conveying chain 12 through the lubrication release hole 9, thereby lubricating the traction conveying chain 12 by injecting lubricating oil.
[0042] The working principle of this embodiment:
[0043] In use, the packaging film is placed on the corresponding clamping fastener 13, and then the drive motor 3 is started, causing the drive motor 3 to rotate the drive sprocket 8. The drive sprocket 8, through rotation, cooperates with the driven sprocket 7 to drive the traction conveyor chain 12. The traction conveyor chain 12 carries multiple clamping fasteners 13 and clamping sliding members 14. When the clamping sliding member 14 slides from the inside of the transmission loosening groove 6 into the inside of the transmission clamping groove 4, the clamping sliding member 15 will use the inclined structure of the conversion inclined groove 5 to move the clamping sliding member 14 downward. The clamping sliding member 14, through its descent, cooperates with the clamping fastener 13 to clamp the film. Then, as the clamping fasteners 13 and clamping sliding members 14 continue to run with the traction conveyor chain 12, they will traction and convey the clamped film, facilitating the movement of the film. The system is brought to the packaging station for use. After the trigger slide plate 16 and trigger slide column 17 on the clamping fixture 13 move to a certain position, the trigger slide column 17 will slide unimpeded through the transition slide 26 and slide into the inclined position of the force receiving slide 27. The force receiving slide 27 uses its own inclined structure to convert the horizontal sliding force of the trigger slide column 17 into a vertical sliding force and provide it to the force transmission component 25. The force transmission component 25 is forced to move the lubricating oil storage cylinder 22 downward. After moving, the guide docking column 10 will be inserted deeper into the lubricating oil storage cylinder 22, so that the guide docking hole 11 is removed from the range of the sealing stop ring 24. The lubricating oil inside the lubricating oil storage cylinder 22 enters the interior of the drive sprocket 8 through the guide docking hole 11. Then, the lubricating oil is injected onto the traction conveyor chain 12 through the lubrication release hole 9, thereby lubricating the traction conveyor chain 12 by injecting lubricating oil.
