Description

Technical Field

[0001] This utility model relates to a feeding device, specifically a bag feeding device for an aluminum-plastic cap packaging machine. Background Technology

[0002] After the aluminum-plastic caps are produced, they need to be bagged and sealed in a sterile and clean environment using plastic bags. Currently, bagging and sealing are generally done manually. Manual bagging and sealing are inefficient and make it difficult to ensure a sterile and clean environment on the production site, which cannot meet the needs of large-scale production.

[0003] Existing patent CN117944955A discloses a filling and sealing integrated machine and its filling and sealing method. In this solution, a bag picking station, a filling station, a sealing station, and a bag placing station are connected in series by a rotating bag conveying device, which can realize the automatic packaging of aluminum-plastic caps. However, in the prior art, the bag feeding device is only suitable for plastic bags of one size, which cannot meet the needs of using packaging bags of different sizes in the production process of aluminum-plastic caps. Utility Model Content

[0004] The purpose of this invention is to provide a bag feeding device for an aluminum-plastic bag packaging machine, so as to solve the problem that the existing bag feeding device of aluminum-plastic cap packaging equipment cannot flexibly adapt to packaging bags of different sizes.

[0005] This utility model is implemented as follows: A bag feeding device for an aluminum-plastic cap packaging machine includes a bag placement tray mounted on a frame. A rotating shaft is horizontally arranged above the front of the bag placement tray. Both ends of the rotating shaft are rotatably connected to the frame. The rotating shaft is driven to rotate around its axis by a rotation drive mechanism. Two swing frames and two first mounting frames are arranged on the rotating shaft. The two swing frames are located at both ends of the rotating shaft and are fixedly connected to the rotating shaft. The two first mounting frames are located inside the two swing frames and are slidably connected to the rotating shaft through sliding sleeves. An adjustment and fixing mechanism for adjusting and fixing the first mounting frames is arranged between the free ends of the two swing frames. A telescopic adjustment mechanism is arranged at the free end of the first mounting frame, and a suction cup mechanism is arranged on the telescopic adjustment mechanism.

[0006] As a further improvement of this utility model, the adjusting and fixing mechanism includes a transverse adjusting frame, with transverse sliding grooves provided at both ends of the transverse adjusting frame, and a fixing bolt threaded onto the first mounting frame, the fixing bolt passing through the sliding groove.

[0007] As a further improvement of this utility model, the telescopic adjustment mechanism includes a first telescopic cylinder disposed at the free end of the first mounting frame, a second mounting frame disposed on the cylinder shaft of the first telescopic cylinder, a second telescopic cylinder disposed on the second mounting frame, and a third mounting frame extending forward on the cylinder shaft of the second telescopic cylinder. The axial directions of the first telescopic cylinder and the second telescopic cylinder are consistent with the length direction of the first mounting frame, and a suction cup mechanism is disposed on the third mounting frame.

[0008] As a further improvement of this utility model, the suction cup mechanism includes a fixed sleeve, a hollow suction cup rod passing through the fixed sleeve, an upper bag suction cup being provided at the lower end of the hollow suction cup rod, an adjusting spring being provided in the fixed sleeve, and a limit ring being provided at the part of the hollow suction cup rod located in the fixed sleeve, the lower end of the adjusting spring contacting the limit ring, and the upper end contacting the top plate of the fixed sleeve.

[0009] As a further improvement of this utility model, the edge thickness of the upper bag suction cup is less than the thickness of the side wall of the upper bag suction cup body, forming a thin-walled portion.

[0010] As a further improvement of this utility model, adjustment holes are provided in the front, back, left and right directions of the packaging bag placement tray, and adjustment baffles are adjustablely installed in the adjustment holes in the four directions, and the adjustment baffles are connected to the adjustment holes by bolts.

[0011] As a further improvement of this utility model, the rotary drive mechanism includes a connecting rod and a swing drive element. The connecting rod is located at the end of the rotary shaft and is fixedly connected to the rotary shaft. One end of the swing drive element is hinged to the connecting rod and the other end is hinged to the frame. The rotary shaft swings around the axis by the extension and retraction of the swing drive element.

[0012] This invention sets the suction cup mechanism on a first connecting rod that can move along the rotation axis. When the swing frame and the first mounting frame are in a vertical state, the suction cup mechanism is located above the upper port of the packaging bag. The distance between the two first connecting rods can be adjusted so that the suction cup can be attached to both ends of the ports of packaging bags of different sizes. The rotation of the rotation axis can drive the swing frame and the first mounting frame to swing to a horizontal state, thereby converting the horizontally placed packaging bag into a vertical state and conveying it to the unloading station for subsequent operations.

[0013] In addition, the suction cup mechanism of this utility model can automatically adapt to the thickness of the stacked packaging bags. As the packaging machine works continuously, the stack of packaging bags in the packaging bag placement tray gradually becomes less and thinner. Since the distance that the suction cup mechanism moves up and down when adsorbing the packaging bags is constant, for packaging bags of different thicknesses, the adjusting spring in the fixing sleeve can ensure that the suction cup is always in contact with the packaging bag at the top.

[0014] Meanwhile, this invention features a thin-walled section around the edge of the upper bag suction cup. During adsorption, the thin-walled section can deform and completely adhere to the surface of the packaging bag, thereby greatly increasing the size of the sealing contact area between the upper bag suction cup and the surface of the packaging bag, ensuring the stability of adsorption. Especially for larger and thinner packaging bags, which experience greater resistance during movement and are easily deformed, this invention can stably adsorb the packaging bag, and the packaging bag will not detach during movement.

Thin-walled section. Detailed Implementation

[0022] The specific embodiments of this utility model will now be described with reference to the accompanying drawings.

[0023] like Figure 1 , Figure 2As shown, the bag feeding device of the aluminum-plastic cap packaging machine of this utility model includes a packaging bag 16 placement tray 2 set on the frame 1. The packaging bag 16 placement tray 2 is horizontally installed at the bottom of the frame 1. A rotating shaft 3 is horizontally arranged above the front of the packaging bag 16 placement tray 2. The rotating shaft 3 is in a horizontal state, and the axial direction of the rotating shaft 3 is consistent with the width direction of the packaging bag 16. The end of the rotating shaft 3 is mounted on the frame 1 through bearings, so that the two ends of the rotating shaft 3 are rotatably connected to the frame 1. The rotating shaft 3 is driven to rotate around the axis by a rotating drive mechanism.

[0024] Two swing frames 4 and two first mounting frames are provided on the rotating shaft 3. The two swing frames 4 are located at both ends of the rotating shaft 3 and are fixedly connected to the rotating shaft 3. The two first mounting frames are located between the two swing frames 4 and are slidably connected to the rotating shaft 3 through sliding sleeves. When the rotating shaft 3 rotates, the swing frames 4 rotate together with the rotating shaft 3. In order for the two first mounting frames to also rotate with the rotating shaft 3, the first mounting frames need to be fixed to the swing frames 4. At the same time, in order for the first mounting frames to move along the rotating shaft 3 to adjust the distance between the two first mounting frames, an adjustment and fixing mechanism for adjusting and fixing the first mounting frames is provided between the free ends of the two swing frames 4. A telescopic adjustment mechanism is provided at the free end of the first mounting frame, and a suction cup mechanism 13 is provided on the telescopic adjustment mechanism. The telescopic adjustment mechanism drives the suction cup mechanism 13 to translate, so that the suction cup mechanism 13 moves closer to or away from the packaging bag 16.

[0025] The adjusting and fixing mechanism includes a horizontal adjusting frame 6, with both ends of the horizontal adjusting frame 6 fixedly connected to the free ends of two swing frames 4 respectively. Horizontal sliding grooves 7 are respectively opened at both ends of the horizontal adjusting frame 6, and the two sliding grooves 7 are symmetrically arranged. The first mounting frame is attached to the horizontal adjusting frame 6, and a fixing bolt 8 is threadedly connected to the first mounting frame. The fixing bolt 8 passes through the sliding groove 7. When the fixing bolt 8 is not tightened, the fixing bolt 8 can move in the sliding groove 7, so that the position of the first mounting frame can be adjusted, thereby further adjusting the distance and position of the two suction cup mechanisms 13 to adapt to packaging bags 16 of different widths. After adjusting the position of the two first mounting frames, tightening the fixing bolt 8 can fix their position.

[0026] The telescopic adjustment mechanism includes a first telescopic cylinder 9 disposed at the free end of the first mounting frame, a second mounting frame 10 disposed on the cylinder shaft of the first telescopic cylinder 9, the second mounting frame 10 having an L-shaped structure, a second telescopic cylinder 11 disposed on the second mounting frame 10, the axial direction of the first telescopic cylinder 9 and the second telescopic cylinder 11 being consistent with the length direction of the first mounting frame, and the second telescopic cylinder 11 being located at the same height inside the first telescopic cylinder 9, a third mounting frame 12 disposed on the cylinder shaft of the second telescopic cylinder 11, the third mounting frame 12 extending a certain length in a direction perpendicular to the cylinder shaft of the second telescopic cylinder 11, and a suction cup mechanism 13 disposed at the end of the third mounting frame 12.

[0027] The first telescopic cylinder 9 is initially in the extended state.

[0028] Generally, the stroke of the second telescopic cylinder 11 is greater than the stroke of the first telescopic cylinder 9.

[0029] The second telescopic cylinder 11 is used by the suction cup mechanism 13 to suction the packaging bag 16 from the packaging bag 16 placement tray 2. When the first connecting frame 5 is in a vertical state, the suction cup mechanism 13 is located above the front of the packaging bag 16. The second telescopic cylinder 11 extends to make the suction cup mechanism 13 move downward and closer to the packaging bag 16. After the suction cup mechanism 13 contacts the packaging bag 16 located at the top of the stack of packaging bags 16, it suctions the packaging bag 16. The second telescopic cylinder 11 retracts and resets to make the suction cup mechanism 13 move upward to the initial position, thereby moving the packaging bag 16 upward and away from the packaging bag 16 below.

[0030] like Figure 3 As shown, the first connecting frame 5 rotates forward and upward to a horizontal position, adjusting the packaging bag 16 to a vertical position and sending it to the next process. In the next process, the packaging bag 16 is clamped and fixed by the bag clamping device. The forward-extending third mounting frame 12 can send the upper end of the packaging bag 16 to a certain height above the horizontal position of the first mounting frame, thereby facilitating subsequent bag clamping, opening, unloading, and sealing processes. After the bag is fed, the first mounting frame needs to rotate back to a vertical position to facilitate the next suction of the packaging bag 16. During the downward swinging reset of the first mounting frame, the forward-extending third mounting frame 12 and the suction cup mechanism 13 will interfere with the vertically fixed packaging bag 16. At this time, the second telescopic cylinder 11 is already in a retracted state, so the retraction of the first telescopic cylinder 9 causes the third mounting frame 12 and the suction cup mechanism 13 to move back a certain distance, thereby avoiding interference with the vertical packaging bag 16 during the swinging process.

[0031] like Figure 4 As shown, adjustment holes 2-1 are provided in the front, back, left, and right directions of the packaging bag 16 placement tray 2. Adjustment baffles 2-2 can be adjusted and installed in the adjustment holes 2-1 in the four directions. The adjustment baffles 2-2 are connected to the adjustment holes 2-1 by bolts. For packaging bags 16 of different sizes, the adjustment baffles 2-2 in the four directions are adjusted to match the outline of the packaging bag 16. The packaging bags 16 stacked together can be placed exactly between the adjustment baffles 2-2, and the position of the packaging bags 16 is restricted by the adjustment baffles 2-2.

[0032] The rotary drive mechanism includes a connecting rod 14 and a swing drive element 15. The connecting rod 14 is located at the end of the rotary shaft 3 and is fixedly connected to the rotary shaft 3. One end of the swing drive element 15 is hinged to the connecting rod 14 and the other end is hinged to the frame 1. The rotary shaft 3 is driven to swing around the axis by the extension and retraction of the swing drive element 15.

[0033] like Figure 5 As shown, the suction cup mechanism 13 includes a fixed sleeve 13-1, which is vertically fixed to the third mounting bracket 12. A hollow suction cup rod 13-2 passes through the fixed sleeve 13-1 and can move axially within the fixed sleeve 13-1. An upper bag suction cup 13-5 is provided at the lower end of the hollow suction cup rod 13-2. The upper bag suction cup 13-5 is connected to the air tube through the hollow suction cup rod 13-2, transmitting the negative pressure of the air tube to the inner cavity of the upper bag suction cup 13-5. An adjusting spring 13-3 is provided inside the fixed sleeve 13-1 and is sleeved on the outside of the hollow suction cup rod 13-2. A limit ring 13-4 is provided on the part of the hollow suction cup rod 13-2 located inside the fixed sleeve 13-1. The lower end of the adjusting spring 13-3 contacts the limit ring 13-4, and the upper end contacts the top plate of the fixed sleeve 13-1. When no external force is applied, the upper bag suction cup 13-5 extends downward to its maximum distance under the elastic force of the spring. When the third mounting bracket 12 gradually moves downward until the upper bag suction cup 13-5 contacts the surface of the packaging bag 16, the adjusting spring 13-3 begins to compress under the action of resistance until the third mounting bracket 12 moves to the lower limit position.

[0034] With the above structure, this utility model can automatically adapt to the thickness of the stacked packaging bags 16. As the packaging machine works continuously, the number and thickness of the stacked packaging bags 16 in the packaging bag 16 placement tray 2 gradually decrease. Since the distance that the third mounting frame 12 and the suction cup mechanism 13 move up and down when adsorbing the packaging bags 16 is constant, within a certain thickness range, the adjusting spring 13-3 in the fixing sleeve 13-1 can keep the suction cup in contact with the packaging bag 16 at the top. In this way, each time only a packaging bag 16 of the corresponding thickness needs to be manually placed into the packaging bag 16 placement tray 2, and the subsequent bag feeding process can be fully automated.

[0035] like Figure 6 As shown, the edge thickness of the upper bag suction cup 13-5 is less than the thickness of the side wall of the upper bag suction cup 13-5 body, forming a thin-walled portion 13-6. Because a thin-walled portion 13-6 is provided at the edge of the upper bag suction cup 13-5, the thin-walled portion 13-6 can deform and completely adhere to the surface of the packaging bag 16 during adsorption, thereby greatly increasing the size of the sealing contact surface between the upper bag suction cup 13-5 and the surface of the packaging bag 16, ensuring the stability of adsorption. Especially for larger and thinner packaging bags 16, the resistance encountered during movement is greater, and the packaging bag 16 is easily deformed. This invention can stably adsorb the packaging bag 16, and the packaging bag 16 will not detach during movement.
