Description

Technical Field

[0001] This utility model relates to the field of bag making machine technology, specifically a three-side seal stand-up pouch making and feeding device. Background Technology

[0002] Three-side seal stand-up pouches are a special type of packaging bag. Their design and structural features give them self-standing and sealing properties, making them widely used in various industries such as food, pharmaceuticals, and cosmetics. During the bag-making process, raw materials are fed into the bag-making machine via rollers to complete the material conveying. The feeding device ensures the continuity and efficiency of the bag-making process and is an important component of the bag-making production line.

[0003] In existing three-side seal stand-up pouch feeding devices, because the feeding end of the bag making machine is at a certain height from the ground, workers usually need to use tools to move the raw material roller for feeding. This method not only involves a large workload and increases the physical exertion of workers, but also makes the entire bag making process less smooth and efficient, thus reducing production efficiency. Furthermore, because the device lacks a mechanism to fix the raw material roller during feeding, the roller is prone to shaking during the ascent, posing a safety hazard. This could lead to the raw material roller falling, causing equipment damage or personal injury, thereby reducing the safety of the device. Utility Model Content

[0004] The purpose of this invention is to provide a three-side seal stand-up pouch feeding device to solve the problems mentioned in the background art.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] Please see Figure 1-4As shown, a three-side seal stand-up pouch feeding device includes a base plate 1, a fixed frame 2 on the top of the base plate 1, an outer shell 3 on the inner side of the fixed frame 2, and a ramp block 4 for feeding on one side of the base plate 1. The ramp block 4 facilitates the raw material roller 16 to roll along its outer side into the inner side of the limiting groove 15. It also includes a power assembly 5 on the outer side of the fixed frame 2, a guide assembly 6 on the inner side of the fixed frame 2, and a movable frame 7 on the outer side of the guide assembly 6. The movable frame 7 can drive the outer shell 3 fixed to one side to move synchronously. A transmission assembly 8 is located on the inner side of the movable frame 7, and two sets of tension springs 9 on the outer side of the movable frame 7 to improve its movement stability. The tension springs 9 at both ends of the movable frame 7 can balance the movement of the movable frame 7 during lifting and lowering, thereby improving its stability. A drive assembly 10 is located on the outer side of the outer shell 3. A transmission block 11 is provided on the outer side of the 0. When the transmission block 11 rotates with the connecting shaft 102, it can drive the two right-angle rods 121 to rotate, causing the two right-angle rods 121 to retract or expand. Two sets of rotating components 12 are symmetrically arranged on the outer side of the transmission block 11. A guide component 13 is provided on the outer side of each set of rotating components 12. A limit frame 14 is provided on the outer side of the guide component 13. When the two limit frames 14 are attached to the two ends of the raw material roller 16, the raw material roller 16 can be fixed to prevent it from falling off during the feeding process. A limit groove 15 is opened on the inner side of the limit frame 14. The limit groove 15 is used to limit the rotation shaft at both ends of the raw material roller 16. Since it is designed at an angle, it can facilitate the loading and unloading of the raw material roller 16 while preventing it from slipping off. The raw material roller 16 is arranged on the inner side of the limit groove 15. The raw material for manufacturing three-side seal stand-up pouches is wrapped around the outer side of the raw material roller 16.

[0023] The power assembly 5 includes a first motor 51 disposed on the outside of the fixed frame 2. The output end of the first motor 51 is provided with a transmission rod 52. When the first motor 51 drives the transmission rod 52 to rotate, it drives the actuating block 81 to perform a semi-circular motion. The guide assembly 6 includes a guide rail 61 disposed on the inside of the fixed frame 2. A slider 62 is slidably connected to the inside of the guide rail 61, and the outside of the slider 62 is fixedly connected to the outside of the movable frame 7. When the movable frame 7 drives the slider 62 to move, the slider 62 slides along the guide rail 61. The guide rail 61 guides the movement path of the movable frame 7 and improves its movement stability. The transmission assembly 8 includes an actuating block 81 disposed at one end of the transmission rod 52. A connecting groove 82 is opened on the inside of the movable frame 7, and the outside of the actuating block 81 is slidably connected to the inside of the connecting groove 82. When the transmission rod 52 rotates, it drives the actuating block 81 to slide in the connecting groove 82, thereby driving the movable frame 7 to move up and down along the guide rail 61.

[0024] The drive assembly 10 includes a second motor 101 disposed on the outside of the housing 3. The output end of the second motor 101 is provided with a connecting shaft 102, and the outer side of the connecting shaft 102 is fixedly connected to the inner side of the transmission block 11. By setting the drive assembly 10, when the second motor 101 drives the connecting shaft 102 to rotate, it will drive the transmission block 11 to rotate synchronously. The rotation assembly 12 includes a right-angle rod 121 rotating on the outside of the transmission block 11. The right-angle rod 121 is L-shaped, and as it rotates with the transmission block 11, it gradually retracts or expands. The right-angle rod 121... The other end is rotatably connected to a connecting seat 122. By setting the connecting seat 122, while moving with one end of the right-angle rod 121, the limiting frame 14 moves along with the connecting block 131. The guide component 13 includes a connecting block 131 set on the outside of the connecting seat 122. A guide groove 132 is opened on one side of the outer shell 3, and the outer side of the connecting block 131 is slidably connected to the inner side of the guide groove 132. By setting the guide component 13, while the limiting frame 14 moves with the connecting block 131, the guide groove 132 restricts their movement path, so that they can move according to the designed route.

[0025] Working principle: In use, the raw material roller 16 is first rolled into the limiting groove 15 by the ramp block 4. Then, the second motor 101 is started, which drives the transmission block 11 through the connecting shaft 102. At the same time, it drives the two right-angle rods 121 connected to its outer side to rotate. As the right-angle rods 121 rotate, they gradually retract, causing the connecting seat 122 to bring the two sets of limiting frames 14 closer together through the connecting block 131, fixing the two ends of the raw material roller 16. Then, the first motor 51 drives the transmission rod 52 to rotate clockwise, causing the actuating block 81 to make a semi-circular motion. At the same time, the actuating block 81 slides along the inner side of the connecting groove 82, causing the moving frame 7 to move upward. Two tension springs 9 balance the stability of the moving frame 7 at both ends, so that the moving frame 7 drives the raw material roller 16 to rise through the outer shell 3. After reaching the feeding end of the bag making machine, the feeding operation is completed.
