Description

Technical Field

[0001] This utility model belongs to the technical field of bag packaging machines, and in particular relates to a support structure for bag conveying in a bag packaging machine. Background Technology

[0002] Bag packaging machines have replaced manual packaging, enabling large and small enterprises to automate packaging. Operators only need to pull out the bag roll and feed it through rollers. The packaging machine then cuts the bag roll, picks up the bag, prints the date, opens the bag, signals the metering device to measure and dispense the material, seals the bag, and outputs the product.

[0003] When a bag packaging machine pulls out and conveys a bag roll using rollers, it uses a clamping roller to compress and tighten the conveyed bag roll, ensuring that the bag roll is in a taut state during the conveying process. Some bag packaging machines adjust the rollers using screws, which is slightly inconvenient. Therefore, a tensioning structure is needed for bag packaging machines during bag conveying, which allows for quick adjustment of the clamping roller to meet the tensioning requirements when the bag roll is pulled out. At the same time, the adjustment efficiency is more convenient, thereby improving the ease of use of the bag packaging machine. Utility Model Content

[0004] The purpose of this utility model is to provide a tensioning structure for bag packaging machine during bag conveying, which allows for rapid adjustment of the pressure roller to meet the tensioning requirements when the bag roll is pulled out, while also making the adjustment more efficient and convenient, thereby improving the ease of use of the bag packaging machine and solving the technical problems mentioned in the background art.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A bag packaging machine has a supporting structure for conveying packaging bags, which includes a crossbar: a T-shaped rod is welded to the surface of the crossbar; a vertical plate is fixedly connected to the end of the vertical plate; a cylinder and a slide rail are fixedly installed on the surface of the vertical plate by bolts; a slider is slidably connected to the surface of the slide rail; a push-pull plate is fixedly connected to the output end of the cylinder by a flange; a dial shaft is fixedly connected to the surface of the slider; a connecting rod is fixedly connected to the surface of the slider; a U-shaped rod is fixedly connected to the end of the connecting rod; a pressure roller is provided on the surface of the crossbar; a rectangular groove adapted to the pressure roller is opened on the surface of the crossbar; a rotating roller is installed on the surface of the crossbar; a packaging machine body is fixedly installed on the surface of the crossbar; and a bag material roll is installed on the surface of the crossbar.

[0006] Preferably, the end of the dial shaft extends into the inner cavity of the push-pull plate, and a rotating sleeve is rotatably connected to the surface of the dial shaft, the surface of the rotating sleeve being in contact with the inner wall of the push-pull plate.

[0007] Preferably, the end of the U-shaped rod extends into the inner cavity of the rectangular groove, and the U-shaped rod is slidably connected to the crossbar.

[0008] Preferably, the end of the U-shaped rod is integrally formed with a pressure block, which is an arc-shaped block.

[0009] Preferably, a ball bearing is embedded in the surface of the pressure block and is rolled to fit against the pressure roller.

[0010] Preferably, a protective ring, which is a rubber ring, is fixedly connected to the surface of the pressing roller.

[0011] Preferably, a clamping block is fixedly installed on the surface of the vertical plate by bolts, and a second ball bearing is embedded in the inner wall of the clamping block and is in contact with the push-pull plate.

[0012] The beneficial effects of this utility model are:

[0013] 1. This utility model uses a push-pull plate to move the dial shaft, which in turn drives the U-shaped rod to move via a slider and connecting rod. The U-shaped rod then presses against the pressure roller, causing the pressure roller to move closer to the rotating roller and support the bag material being pulled out of the bag roll. This allows for rapid adjustment of the pressure roller to meet the support requirements when the bag roll is pulled out, while also making the adjustment more efficient and convenient, thereby improving the ease of use of the bag packaging machine.

[0014] 2. By setting up a rotating sleeve, this utility model provides padding and protection for the inner walls of the dial shaft and the push-pull plate, avoiding excessive wear when the two are in direct contact, thereby extending the service life of the dial shaft and the push-pull plate.

[0015] 3. By setting up the pressure block, this utility model increases the contact area between the U-shaped rod and the pressure roller, ensuring the stability of the pressure roller when it rotates;

[0016] 4. By setting the ball bearings, this utility model provides padding between the pressure block and the pressure roller, thus avoiding excessive wear when the pressure roller directly contacts the pressure block.

[0017] 5. This utility model protects the surface of the pressure roller by setting a protective ring, thus preventing the pressure roller from being damaged when it comes into direct contact with the bag material pulled out of the bag roll.

[0018] 6. This utility model limits the movement of the push-pull plate by using the combination of the clamping block and the second ball bearing, and the wear between them is low, thus ensuring the stability of the push-pull plate during movement. Attached Figure Description

[0026] In the following description, embodiments of the supporting structure for conveying bags in the bag packaging machine of the present invention will be described with reference to the accompanying drawings.

[0027] Example 1:

[0028] Figure 1-4This invention illustrates a bag packaging machine's bag-carrying support structure according to an embodiment of the present invention. It includes a horizontal bar 1 with a T-shaped bar 2 welded to its surface. A vertical plate 3 is fixedly connected to the end of the horizontal bar 1. A cylinder 4 and a slide rail 5 are bolted to the surface of the vertical plate 3. A slider 6 is slidably connected to the surface of the slide rail 5. A push-pull plate 7 is fixedly connected to the output end of the cylinder 4 via a flange. A pivot shaft 8 is fixedly connected to the surface of the slider 6, with its end extending into the inner cavity of the push-pull plate 7. A rotating sleeve 9 is rotatably connected to the surface of the pivot shaft 8, and its surface fits against the inner wall of the push-pull plate 7. The rotating sleeve 9 cushions the pivot shaft 8 and the inner wall of the push-pull plate 7, preventing excessive wear when they are in direct contact, thus extending the service life of the pivot shaft 8 and the push-pull plate 7. A connecting rod 10 is fixedly connected to the surface of the slider 6, with a U-shaped bar 1 fixedly connected to the end of the connecting rod 10. 1. A pressure roller 12 is provided on the surface of the crossbar 1. A rectangular groove 13 adapted to the pressure roller 12 is opened on the surface of the crossbar 1. The end of the U-shaped rod 11 extends into the inner cavity of the rectangular groove 13. The U-shaped rod 11 is slidably connected to the crossbar 1. A pressure block 14 is integrally formed at the end of the U-shaped rod 11. The pressure block 14 is an arc-shaped block. By setting the pressure block 14, the contact area between the U-shaped rod 11 and the pressure roller 12 is increased, ensuring the stability of the pressure roller 12 when rotating. A protective ring 16 is fixedly connected to the surface of the pressure roller 12. The protective ring 16 is a rubber ring. By setting the protective ring 16, the surface of the pressure roller 12 is protected, avoiding the situation where the pressure roller 12 directly contacts the bag material pulled out by the bag material roll 19 and causes damage to the latter. A rotating roller 17 is installed on the surface of the crossbar 1. A packaging machine body 18 is fixedly installed on the surface of the crossbar 1. A bag material roll 19 is installed on the surface of the crossbar 1.

[0029] Example 2:

[0030] Figure 1-4This invention illustrates a bag packaging machine's bag conveying and tensioning structure according to an embodiment of the present invention. It includes a horizontal bar 1 with a T-shaped rod 2 welded to its surface. A vertical plate 3 is fixedly connected to the end of the horizontal plate 3. A cylinder 4 and a slide rail 5 are bolted to the surface of the vertical plate 3. A slider 6 is slidably connected to the surface of the slide rail 5. A push-pull plate 7 is fixedly connected to the output end of the cylinder 4 via a flange. A pivot shaft 8 is fixedly connected to the surface of the slider 6. A connecting rod 10 is fixedly connected to the surface of the slider 6. A U-shaped rod 11 is fixedly connected to the end of the connecting rod 10. A pressure roller 12 is provided on the surface of the horizontal bar 1. A rectangular groove 13 adapted to the pressure roller 12 is formed on the surface of the horizontal bar 1. A ball bearing 15 is embedded and rolled within the surface of the pressure block 14. The first ball 15 is in contact with the pressure roller 12. The setting of the first ball 15 provides padding between the pressure block 14 and the pressure roller 12, avoiding the situation where the pressure roller 12 directly contacts the pressure block 14 and the wear is too large. The surface of the crossbar 1 is equipped with a rotating roller 17, the surface of the packaging machine body 18 is fixedly installed on the surface of the crossbar 1, the surface of the crossbar 1 is equipped with a bag material roll 19, and the surface of the vertical plate 3 is fixedly installed with a clamping block 20 by bolts. The inner wall of the clamping block 20 is embedded with a second ball 21, which is in contact with the push-pull plate 7. Through the cooperation of the clamping block 20 and the second ball 21, the movement of the push-pull plate 7 is limited, and the wear between them is low, thus ensuring the stability of the push-pull plate 7 when it moves.

[0031] Working principle: When using this utility model, the user pulls one side of the bag roll 19 out from between the pressure roller 12 and the rotating roller 17, then activates the cylinder 4 to drive the push-pull plate 7 to move the dial shaft 8. The dial shaft 8 then drives the U-shaped rod 11 to move through the slider 6 and the connecting rod 10. During this process, the slider 6 is limited by the slide rail 5 to prevent the slider 6 from shaking during movement. As a result, the U-shaped rod 11 presses against the pressure roller 12, and then the pressure roller 12 moves closer to the rotating roller 17 to support the bag material pulled out of the bag roll 19. This allows for quick adjustment of the pressure roller to meet the support requirements when the bag roll is pulled out, while also making the adjustment more efficient and convenient, thereby improving the ease of use of the bag packaging machine.

[0032] In summary, the bag packaging machine's bag conveying and tensioning structure utilizes a push-pull plate 7 to move the dial shaft 8. The dial shaft 8 then moves the U-shaped rod 11 via the slider 6 and connecting rod 10. This U-shaped rod 11 presses against the pressure roller 12, causing the pressure roller 12 to move closer to the rotating roller 17 and tighten the bag material pulled from the bag roll 19. This allows for rapid adjustment of the pressure roller to meet the tensioning requirements during bag roll conveying and pulling out, while also improving adjustment efficiency and ease of use of the bag packaging machine.
