Description

Technical Field

[0001] This utility model relates to the field of resin anchoring agent production technology, and in particular to a film conveying device for an automatic packaging machine for resin anchoring agents. Background Technology

[0002] When packaging vertical anchoring agent, the film first needs to be folded and shaped by a packaging machine to form a double-layered cylindrical shape. Then, the cylindrical film is sealed and filled to obtain the finished anchoring agent.

[0003] In the prior art, after the film is folded and formed but before it is sealed, it still needs to go through a certain period of travel. During this period, the cylindrical film is usually not limited or assisted in its transport. The cylindrical film is prone to deformation and local wrinkles during this period, which can lead to gaps before sealing, affecting the sealing effect and even causing cracks to remain after sealing. This can result in leakage of the finished resin anchoring agent after filling. Therefore, there is a need for a film conveying device for an automatic packaging machine for resin anchoring agents.

The electrostatic rib is located in the middle of the second conveyor wheel and is adapted to the opening of the cylindrical film. The electrostatic rib carries static electricity and can attract the two sides of the opening of the cylindrical film to close it.

[0010] The drive motor is mounted on the outside of the frame, and its output shaft is connected to one end of the shaft of the first conveyor wheel.

[0014] Preferably, electrostatic ribs are fixedly fitted on both second conveyor wheels;

[0015] The width and diameter of the upper electrostatic rib are both greater than those of the lower electrostatic rib, and the width of the upper electrostatic rib is the same as the opening width of the cylindrical film.

[0019] Preferably, the connection structure includes an adjusting bolt, which is threaded through the frame and rotatably connected to the side of the friction block away from the first conveying wheel. Guide rods are provided on both sides of the adjusting bolt, which slide through the frame and are fixed to the side of the friction block away from the first conveying wheel.

[0020] Preferably, the transmission mechanism includes a transmission pulley set and a reversing transmission gear set.

[0023] 2.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example: Reference Figures 1-4 The automatic packaging machine for resin anchoring agents shown includes a film conveying device comprising:

[0034] The first conveying wheel 1 is rotatably mounted between the two side frames 100 via a rotating shaft. The first conveying wheel 1 has a V-shaped limiting groove 11 formed on it for limiting the overlapping part of the folded edge of the cylindrical film 200.

[0035] The second conveyor wheel 2 is rotatably mounted between the two side frames 100 via a rotating shaft. The second conveyor wheel 2 has an arc-shaped wall 21 that fits into the opening of the cylindrical film 200.

[0036] The first conveying wheel 1 and the second conveying wheel 2 are located on the front and rear sides of the cylindrical film 200, respectively. The first conveying wheel 1 is located on the side of the overlapping edge of the cylindrical film 200, and the second conveying wheel 2 is located on the side of the opening of the cylindrical film 200.

[0037] The electrostatic rib ring 3 is fixedly sleeved on the second conveying wheel 2. The electrostatic rib ring 3 is located in the middle of the second conveying wheel 2 and is adapted to the opening of the cylindrical film 200. The electrostatic rib ring 3 carries static electricity and can attract the two sides of the opening of the cylindrical film 200 to close together, so that the opening of the cylindrical film 200 is closed.

[0038] Drive motor 4 is mounted on the outside of frame 100, and the output shaft of drive motor 4 is connected to one end of the shaft of the first conveying wheel 1.

[0039] A transmission mechanism is used to drive between the first conveyor wheel 1 and the second conveyor wheel 2, and to cause the first conveyor wheel 1 and the second conveyor wheel 2 to rotate in opposite directions.

[0040] Based on the above structure, the first conveying wheel 1 and the second conveying wheel 2 are used to bond the cylindrical film 200 and assist in conveying the cylindrical film 200. When conveying, the first conveying wheel 1 can limit one side of the overlapping edge of the cylindrical film 200, so that the cylindrical film 200 can maintain a stable posture after forming and before sealing. At the same time, the electrostatic rib ring 3 with static electricity is used to attract the two sides of the opening of the cylindrical film 200, reducing the gap between the two sides of the opening of the cylindrical film 200, improving the subsequent sealing effect, ensuring that there is no gap at the opening of the cylindrical film 200 after sealing, and avoiding leakage of the resin anchoring agent after filling.

[0041] Furthermore, there are two of each of the first conveying wheel 1 and the second conveying wheel 2. The two first conveying wheels 1 are located on the same side of the cylindrical film 200 and are distributed vertically and horizontally. Similarly, the two second conveying wheels 2 are located on the same side of the cylindrical film 200 and are distributed vertically and horizontally. Using two first conveying wheels 1 and two second conveying wheels 2 can further enhance the limiting and shaping effect on the cylindrical film 200 and ensure that the cylindrical film 200 maintains a more stable posture during conveying.

[0042] The transmission mechanism is also used to drive between the two first conveyor wheels 1 and the two second conveyor wheels 2, so that the two first conveyor wheels 1 and the two second conveyor wheels 2 rotate synchronously.

[0043] Furthermore, electrostatic rib rings 3 are fixedly fitted on both second conveyor wheels 2;

[0044] Among them, the width and diameter of the upper electrostatic rib ring 3 are both greater than the width and diameter of the lower electrostatic rib ring 3, and the width of the upper electrostatic rib ring 3 is the same as the opening width of the cylindrical film 200.

[0045] By setting the upper and lower electrostatic ribs 3 to different sizes, the opening of the cylindrical film 200 can be progressively contracted, making the gap of the opening of the cylindrical film 200 smaller, which is more conducive to the formation of a complete sealing structure of the cylindrical film 200 during sealing and welding, thus avoiding leakage.

[0046] Furthermore, a friction wheel 7 is provided on the side of the second conveyor wheel 2 away from the cylindrical film 200. The friction wheel 7 is fixed to the two side frames 100 by a fixing rod. A friction groove 71 adapted to the electrostatic rib ring 3 is opened in the middle of the friction wheel 7.

[0047] Two friction wheels 7 are also provided and are distributed vertically and horizontally. The upper friction wheel 7 is adapted to the upper electrostatic rib ring 3, and the lower friction wheel 7 is adapted to the lower electrostatic rib ring 3.

[0048] A friction block 8 is provided on the side of the first conveying wheel 1 away from the cylindrical film 200. The friction block 8 is connected to the frame 100 on the back side by a connecting structure with an adjustable distance. The front end of the friction block 8 forms a friction arc wall 81 that fits the arc surface of the first conveying wheel 1.

[0049] By setting the friction wheel 7 and friction block 8, they can cooperate with the first conveying wheel 1 and the electrostatic rib ring 3, so that the first conveying wheel 1 and the electrostatic rib ring 3 can generate static electricity when rotating, preventing the tubular film 200 from detaching from the first conveying wheel 1 or the second conveying wheel 2 during the conveying process, and adsorbing the two sides of the tubular film 200, so that the tubular film 200 forms a predetermined shape, ensuring that the front and rear sides of the tubular film 200 can form a sealed structure during sealing, which facilitates subsequent filling.

[0050] Furthermore, the connection structure includes an adjusting bolt 9, which is threaded through the frame 100 and rotatably connected to the side of the friction block 8 away from the first conveying wheel 1. Guide rods 91 are provided on both sides of the adjusting bolt 9, and the guide rods 91 slide through the frame 100 and are fixed to the side of the friction block 8 away from the first conveying wheel 1.

[0051] The gap between the friction block 8 and the first conveying wheel 1 can be adjusted by turning the adjusting bolt 9. After a period of use, the friction block 8 and the first conveying wheel 1 can be adjusted to maintain a good fit and fit, so that the first conveying wheel 1 can maintain a good adsorption and shaping effect during long-term use.

[0052] Furthermore, the transmission mechanism includes a transmission pulley set 5 and a reversing transmission gear set 6. The transmission pulley set 5 includes a first pulley set 51 and a second pulley set 52. The first pulley set 51 is provided with two sets and is respectively installed at the ends of the shafts of the two first conveying wheels 1 and the two second conveying wheels 2. The reversing transmission gear set 6 is installed at the end of the shaft of the first conveying wheel 1 away from the first pulley set 51. The second pulley set 52 is connected to the reversing transmission gear set 6 through a shaft drive and is drively connected to the end of the shaft of one of the second conveying wheels 2.

[0053] The working principle of this utility model is as follows: In daily use, the drive motor 4 drives one of the first conveying wheels 1 to rotate. One of the first conveying wheels 1 drives another first conveying wheel 1 to rotate through a set of first pulleys 51. The other first conveying wheel 1 drives one of the second conveying wheels 2 to rotate through a reversing transmission gear set 6 and a second pulley set 52. One of the second conveying wheels 2 drives another second conveying wheel 2 to rotate through another set of first pulleys 51. Due to the reversing action of the reversing transmission gear set 6, the two first conveying wheels 1 and the two second conveying wheels 2 rotate in opposite directions to convey the cylindrical film 200 in the middle.

[0054] During the conveying process, the friction wheel 7 rubs against the electrostatic rib 3 on the second conveying wheel 2, causing the electrostatic rib 3 to carry static electricity. The friction block 8 rubs against the first conveying wheel 1, causing the first conveying wheel 1 to carry static electricity. This allows the first conveying wheel 1 to adsorb and limit one side of the overlapping edge of the tubular film 200 during conveying. The tubular film 200 maintains a stable posture after forming and before sealing. At the same time, the electrostatic rib 3 with static electricity adsorbs the two sides of the opening of the tubular film 200, reducing the gap between the two sides of the opening of the tubular film 200, improving the subsequent sealing effect, and ensuring that there is no gap at the opening of the tubular film 200 after sealing, thus avoiding leakage of the resin anchoring agent after filling.

[0055] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
