Description

Technical Field

[0001] This invention relates to the field of bag sealing and packaging technology, and in particular to a bag clamping, conveying and leveling device. Background Technology

[0002] When using existing material belt clamping and conveying leveling devices, the two ends of the material bag are at different heights before entering the sealing position after the material is filled, and there is a lack of leveling operation. Because the material bags are at different horizontal heights, the excess part of the sealed material bag needs to be cut off with a cutter to level it. The cut-off material bags are solid waste, causing environmental pollution.

[0003] Therefore, we propose a bag clamping, conveying, and leveling device. Summary of the Invention

[0004] The main objective of this invention is to provide a bag clamping, conveying, and leveling device, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A bag clamping, conveying, and leveling device includes a housing, a conveying motor, and a clamping cylinder. Parallel conveying rollers are arranged at the bottom of the housing. A cover plate is mounted on the top of the housing via a second bolt. A coupling is mounted on the top of the cover plate. A coupling seat is mounted on the top of the coupling via a first bolt. A conveying reducer is mounted on the top of the coupling seat. A conveying motor is mounted on the top of the conveying reducer. A through hole is formed in the side wall of the housing, and a single lug is inserted through the through hole. A clamping cylinder is mounted at the end of the single lug. The clamping cylinder is mounted on the outer wall of the housing via a third bolt. The top of the conveying rollers... A first driven tooth and a second driven tooth are respectively installed. The first driven tooth is meshed with a first driving tooth, and the second driven tooth is meshed with a second driving tooth. The first driving tooth is sleeved on the outer circumference of the driving shaft, and the second driving tooth is sleeved on the outer circumference of the third driven shaft. The first driven tooth is sleeved on the outer circumference of the second driven shaft, and the second driven tooth is sleeved on the outer circumference of the first driven shaft. A third retaining spring is provided between the second driven shaft and the first driven tooth, and between the third driven shaft and the second driving tooth. A swing arm is connected to the top of the driving shaft. The top of the swing arm is connected to the conveyor reducer through the second retaining spring, the first bearing, and the first retaining spring.

[0007] Furthermore, a flange is connected to the top of the clamping cylinder, which is installed at the bottom of the lifting electric cylinder, and a lifting servo motor is installed on the top of the lifting electric cylinder.

[0008] Furthermore, the bottom of the housing is equipped with a horizontal photoelectric sensor and a start-up photoelectric sensor.

[0009] Furthermore, the end of the single earring is rotatably connected to the outer periphery of the third driven shaft.

[0010] Furthermore, a connecting block is installed between the lifting electric cylinder and the lifting servo motor.

[0011] Compared with the prior art, the present invention has the following advantages: before sealing, the material bag filled with material can be adjusted horizontally and vertically to make the relative distance between the upper edge of the material bag and the sealing point equal; after the material bag is adjusted horizontally and vertically, the relative distance between the upper edge of the material bag and the sealing point is equal, eliminating the need for cutting, preventing the generation of solid waste, and reducing environmental pollution.

[0014] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0015] like Figure 1As shown, the bag clamping, conveying, and leveling device includes a housing 22, a conveying motor 5, and a clamping cylinder 25. Parallel conveying rollers 23 are arranged at the bottom of the housing 22. A cover plate 11 is mounted on the top of the housing 22 via a second bolt 10. A coupling 9 is mounted on the top of the cover plate 11. A coupling seat 7 is mounted on the top of the coupling 9 via a first bolt 8. A conveying reducer 6 is mounted on the top of the coupling seat 7. The conveying motor 5 is mounted on the top of the conveying reducer 6. The side wall of the housing 22 has a through hole, and a single lug 26 passes through the through hole. A clamping cylinder 25 is mounted at the end of the single lug 26. The clamping cylinder 25 is mounted on the outer wall of the housing 22 via a third bolt 24. The tops of the conveying rollers 23 are respectively... The drive shaft 17 is equipped with a first driven tooth 21 and a second driven tooth 29. The first driven tooth 21 is engaged with a first driving tooth 20, and the second driven tooth 29 is engaged with a second driving tooth 28. The first driving tooth 20 is sleeved on the outer circumference of the drive shaft 17, and the second driving tooth 28 is sleeved on the outer circumference of the third driven shaft 27. The first driven tooth 21 is sleeved on the outer circumference of the second driven shaft 18, and the second driven tooth 29 is sleeved on the outer circumference of the first driven shaft 16. A third retaining ring 19 is provided between the second driven shaft 18 and the first driven tooth 21, and between the third driven shaft 27 and the second driving tooth 28. A swing arm 15 is connected to the top of the drive shaft 17, and the top of the swing arm 15 is connected to the conveyor reducer 6 through a second retaining ring 14, a first bearing 13, and a first retaining ring 12.

[0016] The clamping cylinder 25 is connected to a flange 4 at its top and is installed at the bottom of the lifting cylinder 3. The lifting servo motor 1 is installed at the top of the lifting cylinder 3.

[0017] The bottom of the housing 22 is provided with a horizontal photoelectric sensor 30 and a start photoelectric sensor 31.

[0018] The end of the single earring 26 is rotatably connected to the outer periphery of the third driven shaft 27.

[0019] A connecting block 2 is installed between the lifting electric cylinder 3 and the lifting servo motor 1.

[0020] It should be noted that this invention is a bag clamping, conveying, and leveling device. The clamping, conveying, and leveling device is interlocked with the existing conveying equipment. When the original equipment starts, the clamping, conveying, and leveling device starts, and the conveying motor 5 starts. The conveying motor 5 drives the conveying reducer 6, which in turn drives the conveying rollers 23 to rotate through the driven and driven teeth. Before the bag enters the bag clamping, conveying, and leveling device, the clamping cylinder 25 opens, causing the conveying rollers 23 to separate, facilitating the bag's entry between the conveying rollers 23. After the bag enters, the clamping cylinder 25 closes, and the conveying rollers 23 clamp the bag between them. A speed regulator is used to adjust the conveying speed of the conveying rollers 23 to match the speed of the sealing equipment. A preset horizontal photoelectric sensor 30 is used to establish a reference horizontal height, and the bag detection photoelectric sensor detects the bag's position. After the bag enters, the bag clamping, conveying, and leveling device is activated. The light transmission and occlusion status of the horizontal photoelectric sensor 30 are monitored. If the bag is transparent, it indicates the bag is below the preset horizontal height, and the clamping, conveying, and leveling device moves upward. If the bag is occluded, it indicates the bag is above the preset horizontal height, and the device moves downward. This information is fed back to the control unit. The control unit issues commands based on the received signals, and the lifting servo cylinder moves the clamping, conveying, and leveling device up and down accordingly. During the bag adjustment process, the clamping, conveying, and leveling device is constantly in a dynamic adjustment state, thus achieving horizontal and height adjustments to ensure all bags are at a uniform horizontal height. The adjusted bags immediately proceed to the sealing area for sealing, ensuring the distance between the top edge of the bag and the sealing point is equal.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
