[0025] Embodiment 1

[0026] As Figures 1 to 9 shown, the automatic tank insertion device includes a sprocket 13, a chain, and a hanging rod 14. The hanging rod 14 is fixed to the chain at equal intervals, and the chain is movably connected to the sprocket 13. It further includes: a fixed seat 11; a rotating shaft 21, the rotating shaft 21 is a hollow shaft, and the rotating shaft 21 is rotatably installed on the fixed seat 11, and the sprocket 13 is fixed on the rotating shaft

[21] ; a sliding shaft 22, one end of the sliding shaft 22 is fixed to the rotating shaft 21 and is arranged in a circumferential array around the axis of the rotating shaft 21. The sliding shaft 22 corresponds to the sprocket 13, and the sliding shaft 22 is provided with a first cavity 222 and a first through hole 221 that communicate with each other; a feeding seat 23, the feeding seat 23 is slidably inserted on the sliding shaft 22, the feeding seat 23 is provided with a material suction groove 231, and the bottom of the material suction groove 231 is provided with a feeding air hole 233, and the feeding air hole 233 communicates with the first through hole 221; a rotating air vent disk 31, the rotating air vent disk 31 is connected to the other end of the sliding shaft 22, and the rotating air vent disk 31 is provided with a plurality of second through holes 311, and the second through holes 311 correspond to the sliding shaft 22 and communicate with the first cavity 222; a central shaft 27, the central shaft 27 is provided with a second cavity 271 for inhaling air, the central shaft 27 is rotatably installed inside the rotating shaft 21, and the rotating air vent disk 31 is rotatably installed on the central shaft 27; a first air pipe 28, the first air pipe 28 is fixed in the second cavity 271, and the first air pipe 28 is used for blowing air; an air exchange device, the air exchange device is fixed on the central shaft 27, the air exchange device is slidably connected to the rotating air vent disk 31, and the air exchange device is used for switching between the feeding air hole 233 and the second cavity 271 and the first air pipe 28 when the feeding seat 23 adsorbs and separates the tank body 10; a reciprocating movement device, the reciprocating movement device is respectively connected to the feeding seat 23 and the central shaft 27, and is used to drive the feeding seat 23 to reciprocate along the sliding shaft 22; a driving device, the driving device is fixed on the fixed seat 11 and is connected to the rotating shaft 21, and is used to drive the rotating shaft 21 to rotate.

[0027] The automatic tank body insertion device includes both a material suction state and a material blowing state. In the material suction state, the feeding seat 23 is located on one side of the rotating ventilation disc 31. The feeding air holes 233 on the feeding seat 23 communicate with the second cavity 271 through a ventilation device, and the feeding air holes 233 are used to adsorb the tank body 10. In the material blowing state, the feeding seat 23 is located on one side of the sprocket 13. The feeding air holes 233 communicate with the first air pipe 28 through a ventilation device, and the feeding air holes 233 are used to separate the tank body 10. When converting from the material suction state to the material blowing state, the feeding seat 23 moves from the rotating ventilation disc 31 to the sprocket 13 through the driving sleeve 25, the driving shaft 26, and the driving rod 24, and the tank body 10 is inserted on the hanging rod 14.

[0028] The material suction groove 231 is a V-shaped groove or an arc groove, which is convenient for positioning the tank body 10, preventing the tank body 10 from shaking, so as to ensure that the tank body 10 is stably adsorbed in the material suction groove 231 and can be accurately inserted onto the hanging rod 14. Elastic cushion plates can be installed on both sides of the material suction groove 231 to protect the surface of the tank body 10.

[0029] A material seat through hole 234 is provided inside the feeding seat 23. Sliding sleeves and sealing rings are installed at both ends of the material seat through hole 234. The sliding sleeves and sealing rings are slidably inserted on the sliding shaft 22. The diameter of the material seat through hole 234 is larger than the outer diameter of the sliding shaft 22, so as to ensure that the feeding air holes 233 communicate with the first through hole 221.

[0030] A hole communicating with the second through hole 311 is provided on the side surface of one end of the sliding shaft 22.

[0031] A rotating seat 12 is installed on the fixed seat 11. The rotating shaft 21 is installed on the rotating seat 12 through a bearing. The rotating seat 12 is provided with a relatively long installation hole to ensure that the rotating shaft 21 rotates around its axis, and the axis remains horizontal without skew.

[0032] The central shaft 27 is connected to the rotating shaft 21 through a bearing.

[0033] The hanging rods 14 correspond to the sliding shafts 22 one by one, so as to ensure that each hanging rod 14 can be loaded with the tank body 10.

[0034] The feeding seat 23 reciprocates along the sliding shaft 22 to insert the tank body 10 onto the hanging rod 14. The adsorption and separation of the tank body 10 are realized by suction and blowing. First, the tank body 10 is adsorbed, and after the tank body 10 is inserted onto the hanging rod 14, blowing is carried out to make the tank body 10 leave the feeding seat 23, and the tank body 10 moves with the hanging rod 14.

[0035] The feeding seat 23 rotates while moving along the sliding shaft 22.

[0036] The ventilation device keeps the tank body 10 in an air suction state when it is adsorbed onto the feeding seat 23 and then inserted onto the hanging rod 14, ensuring that the tank body 10 does not detach from the feeding seat 23. When the tank body 10 leaves the feeding seat 23, the ventilation device makes the feeding air hole 233 blow air to separate the tank body 10 from the feeding seat 23, preventing the tank body 10 from sticking to the feeding seat 23 due to factors such as static electricity.

[0037] The ventilation device includes a ventilation seat 33. The ventilation seat 33 is fixed on the central shaft 27. A communication groove 335 is provided on the ventilation seat 33. The communication groove 335 is located at one end of the ventilation seat 33. The other end of the ventilation seat 33 is slidably pressed against the rotating ventilation disc 31. The communication groove 335 communicates with the second cavity 271. An air suction groove 331 and a blowing hole 332 are provided at the bottom of the communication groove 335. The air suction groove 331 is used for the second cavity 271 to communicate with some of the second through holes 311 when the feeding air hole 233 adsorbs the tank body 10. The blowing hole 332 communicates with the first air pipe 28. The blowing hole 332 is used for the first air pipe 28 to communicate with at least one of the second through holes 311 when the feeding air hole 233 separates the tank body 10. A sealing cover plate 34 is fixed at one end of the ventilation seat 33 to seal the communication groove 335. <x

[0038] The air suction groove 331 and the blowing hole 332 achieve the switching between air suction and blowing, with a simple structure and no impact on rotation.

[0039] The ventilation seat 33 is stationary, and the rotating ventilation disc 31 rotates. That is, the air suction position and the blowing position are fixed. The air suction side adsorbs the tank body 10, and the blowing side allows the tank body 10 to leave the feeding seat 23 and enter the next process following the chain.

[0040] The second through hole 311 is actually an air path. One end of the second through hole 311 communicates with the sliding shaft 22, and the other end is located on the contact surface between the rotating ventilation disc 31 and the ventilation seat 33 and is arranged in an annular array. When the second through hole 311 communicates with the air suction groove 331, the feeding seat 23 sucks air to adsorb the tank body 10. When the second through hole 311 communicates with the blowing hole 332, air is blown to blow the tank body 10 away from the suction trough 231.

[0041] The reciprocating movement device includes: a driving sleeve 25, on which a plurality of driving grooves 251 are provided. The two ends of the driving sleeve 25 are respectively connected to the rotating shaft 21 and the rotating ventilation disc 31. A driving shaft 26 is fixed on the central shaft 27 and is located inside the driving sleeve 25. A reciprocating groove 261 is provided on the driving shaft 26. A driving rod 24, one end of which is fixed on the feeding seat 23, and the driving rod 24 is slidably inserted into the driving groove 251 and the reciprocating groove 261.

[0042] The driving groove 251 is a kidney-shaped groove and is arranged along the axis of the driving sleeve 25.

[0043] The reciprocating groove 261 is arranged around the outer circular surface of the drive shaft 26, connected end to end, and is a curve. During material suction, the reciprocating groove 261 gradually moves from the rotating air vent disk 31 towards the sprocket 13, thereby enabling the feeding seat 23 to move from the rotating air vent disk 31 towards the sprocket 13, and further enabling the tank body 10 to be inserted onto the hanging rod 14. During material discharge, the reciprocating groove 261 gradually moves from the sprocket 13 towards the rotating air vent disk 31, ensuring that the feeding seat 23 does not interfere with the hanging rod 14 when adsorbing the tank body 10.

[0044] The drive sleeve 25 rotates, the drive shaft 26 remains stationary, and the reciprocating groove 261 remains stationary. The drive sleeve 25 causes the drive rod 24 to move along the reciprocating groove 261, thereby driving the feeding seat 23 to reciprocate.

[0045] Two bearings are installed along the axis of the drive rod 24. One bearing is located within the drive groove 251, and the other bearing is located within the reciprocating groove 261. The bearings can convert the sliding friction between the drive rod 24 and the drive groove 251 and the reciprocating groove 261 into rolling friction, thereby ensuring the service life. The drive rod 24 also limits the position of the feeding seat 23, preventing the feeding seat 23 from rotating around the sliding shaft 22.

[0046] The drive device includes: a drive motor 41, which is fixed on the fixed seat 11; a driving belt pulley 42, which is fixed on the drive motor 41; a driven belt pulley 44, which is fixed on the rotating shaft 21; and a synchronous belt 43, which is sleeved on the driving belt pulley 42 and the driven belt pulley 44 respectively. The drive motor 41 uses a servo motor, with accurate speed control, ensuring that the air suction and blowing are synchronized with the adsorption and separation of the tank body 10, and the operation is stable and reliable.

[0047] During operation, the tank body 10 is stacked on the suction side of the tank body automatic insertion device through the conveying device. The air supply holes 233 of the feed seat 23 on the suction side are successively communicated with the second cavity 271 through the first through hole 221, the first cavity 222, the second through hole 311, the air suction groove 331 and the communication groove 335. Since the air supply holes 233 are sucking air, the tank body 10 is adsorbed into the suction groove 231 of the feed seat 23. The drive motor 41 drives the rotating shaft 21 to rotate, and the rotating shaft 21 drives the sliding shaft 22, the feed seat 23, the rotating air vent disk 31 and the drive sleeve 25 to rotate. The sprocket 13 drives the chain to rotate synchronously. The tank body 10 adsorbed on the feed seat 23 follows the feed seat 23 to move while rotating and moves towards the sprocket 13. When the feed seat 23 moves to the extreme position on one side of the sprocket 13, the insertion action of the tank body 10 is completed, and the tank body 10 is inserted onto the hanging rod 14. The feed seat 23 continues to rotate around the axis of the central shaft 27 and then gradually moves towards the rotating air vent disk 31. When the air supply holes 233 are successively communicated with the air blowing holes 332 through the first through hole 221, the first cavity 222 and the second through hole 311, the air blowing pipe is communicated with the air supply holes 233 through the air blowing holes 332, and the air supply holes 233 blow air to separate the tank body 10 in the suction groove 231 from the suction groove 231. At this time, the hanging rod 14 follows the chain to leave the tank body automatic insertion device, preventing the hanging rod 14 from moving while the tank body 10 remains stationary, which may cause deformation of the tank body 10 or abnormal operation, and completing the automatic insertion of the tank body 10.

[0048] Embodiment 2

[0049] On the basis of the above Embodiment 1, it further includes a ventilation plate 32. The ventilation plate 32 is fixed on the rotating air vent disk 31. A plurality of third through holes 321 are arranged in an annular array on the ventilation plate 32. The third through holes 321 correspond to the second through holes 311. The ventilation seat 33 is slidably pressed on the ventilation plate 32. The air suction groove 331 and the air blowing holes 332 respectively correspond to the third through holes 321.

[0050] The ventilation plate 32 is made of wear-resistant engineering plastic, such as polytetrafluoroethylene, which is wear-resistant and has good sealing performance. The ventilation plate 32 facilitates the processing of the rotating air vent disk 31 and the ventilation seat 33 and can effectively improve the sealing performance.

[0051] Embodiment 3

[0052] On the basis of the above-mentioned First Embodiment or Second Embodiment, the sealing cover plate 34 is fixed on the central shaft 27, the ventilation seat 33 is slidably mounted on the central shaft 27 and is movably connected to the sealing cover plate 34; further included is a sealing spring 35. There are multiple sealing springs 35, and the sealing springs 35 are located between the sealing cover plate 34 and the ventilation seat 33. The sealing springs 35 are used to press the fixed seat 11 tightly against the rotating ventilation disc 31 or the ventilation plate 32. By pressing the ventilation seat 33 tightly against the rotating ventilation disc 31 or the ventilation plate 32 through the sealing springs 35, the sealing performance is improved, good adsorption performance is ensured, and the tank body 10 is stably adsorbed in the material suction groove 231.

[0053] Embodiment Four

[0054] On the basis of any of the above-mentioned embodiments, the ventilation seat 33 is provided with a fourth through hole 333 and a ventilation groove 334. The ventilation groove 334 is located on one side of the rotating ventilation disc 31. The fourth through hole 333 communicates with the ventilation groove 334 and corresponds to the second through hole 311.

[0055] Add a step of communicating with the atmosphere between blowing and suction, so that the tank body 10 will not be blown after being inserted into the hanging rod 14 and before being separated from the feeding seat 23, avoiding the rolling and shaking of the tank body 10 caused by blowing. At this time, blowing is likely to cause the tank body 10 to break away from the hanging rod 14 and surface scratches and other defects caused by the shaking of the raceway, etc. Therefore, no blowing is performed at this time, and the tank body 10 is in a free state. Then the hanging rod 14 and the tank body 10 leave the feeding seat 23. At this time, blowing is performed, and the tank body 10 is not affected.

[0056] Embodiment Five

[0057] On the basis of any of the above-mentioned examples, an overload protection device is further included. The overload protection device includes: a detection seat 52, the detection seat 52 is fixed on the fixed seat 11; a detection shaft 53, the detection shaft 53 is slidably inserted into the detection seat 52; a detection spring 55, the detection spring 55 is movably inserted into the detection shaft 53; a detection roller 54, the detection roller 54 is rotatably mounted at one end of the detection shaft 53; a detection disc 51, the detection disc 51 is fixed on the central shaft 27, a limiting groove 511 is provided on the detection disc 51, the detection roller 54 is movably located in the limiting groove 511, and the detection spring 55 is used to press the detection roller 54 tightly in the limiting groove 511; an overload sensor 56, the overload sensor 56 is a proximity switch or a photoelectric sensor, and is used to detect the detection shaft 53 when the detection roller 54 drives the detection shaft 53 to move during overload.

[0058] The overload protection device prevents the center shaft 27 from rotating with the rotating shaft 21 due to a malfunction. The rotation of the center shaft 27 following the rotating shaft 21 will cause the hanging rod 14 to separate from the feeding seat 23, while the feeding seat 23 is still in the suction state, and the feeding seat 23 does not move along the sliding shaft 22, causing the hanging rod 14 on the suction side to crush the tank body 10, and the tank body 10 to be pulled on the discharge side. Therefore, it is necessary to ensure that the center shaft 27 does not rotate with the rotating shaft 21, and stop when rotation occurs.

[0059] The detection disk 51 rotates, and the detection roller 54 is forced to push the detection shaft 53 to move along the axis of the detection shaft 53. The overload sensor 56 detects the detection roller 54, indicating that an overload occurs, and the automatic can insertion device stops.

[0060] The automatic tank insertion device provided by the present invention has a simple structure, is not easy to damage the tank by adsorption, realizes the movement of the tank by the reciprocating groove, and accurately and reliably inserts the tank into the hanging rod in sequence, with a high degree of automation and high work efficiency.

[0061] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are intended solely to illustrate the principles of the present invention and are not to be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art will readily devise other specific embodiments of the present invention without inventive effort, and such embodiments will fall within the scope of protection of the claims of the present invention.
