Description

Technical Field

[0001] This utility model relates to the field of packaging bag technology, and in particular to a feeding structure for a suction tube in the production of packaging bags with suction nozzles. Background Technology

[0002] A spouted pouch is a flexible packaging container equipped with a spout structure. It is usually made of plastic or composite materials. Its bottom is designed as a self-supporting structure for stable standing, and the top or side has a spout for easy drinking or pouring of liquids and semi-fluids (such as juice, sauces, cosmetics). The packaging uses a highly airtight spout (such as a leak-proof design) to ensure the hygiene and freshness of the contents and simplify the usage process. It is suitable for many fields such as food, beverages, daily chemicals, and pet products.

[0003] In the production of packaging bags with spouts, the spout tube and the plastic packaging bag are usually placed simultaneously in a designated position within a heat-sealing device for heat sealing. This heat-sealing process connects the plastic packaging bag and the spout tube. However, the feeding of spout tubes in current production is still done manually, where each spout tube is placed one by one into the heat-sealing device to connect with the plastic packaging bag. This feeding method is not only inefficient, but also prone to errors, as it is difficult to maintain a consistent pace or to accidentally place multiple spout tubes at once. Therefore, this invention proposes a spout tube feeding structure for the production of packaging bags with spouts to solve the problems existing in the prior art. Utility Model Content

[0004] To address the aforementioned issues, this utility model proposes a feeding structure for the production of suction tubes in packaging bags with suction nozzles. This feeding structure achieves the effect of feeding at equal intervals, and feeds one suction tube at a time, preventing overfeeding. It is convenient to use and more reliable.

[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a feeding structure for a suction tube in the production of a packaging bag with a suction nozzle, including a feeding channel and a guiding channel, wherein a connecting port is provided at one end of the rear side of the feeding channel, and the guiding channel is obliquely connected to the connecting port;

[0006] The bottom of the feeding channel is provided with a bottom hopper at one end, and a first support arm is rotatably provided at the front end of the bottom hopper. A second support arm is rotatably provided at the other front end of the bottom hopper. A toggle arm is rotatably provided at the upper end of the first support arm. The upper end of the second support arm and the middle end of the toggle arm are hinged together. A toggle rod is provided at the upper end of the inner side of the toggle arm, and the toggle rod is located above the feeding channel. A motor is provided at one end inside the bottom hopper, and the output end of the motor is connected to the first support arm.

[0007] A further improvement is that a material box is provided on the rear side above the material guide channel, and an outlet communicating with the material guide channel is provided on the lower front side of the material box. The material box is used to accommodate the suction tube.

[0008] A further improvement is that the upper opening of the material box is used to connect a pressurizing device, and the pressurizing device is used to push the suction tube downward.

[0009] A further improvement is that a protective cover is provided at the top of the feeding channel, away from the connecting opening.

[0010] A further improvement is that the protective cover is integrally formed with the feeding channel, and the diameter of the protective cover is larger than the diameter of the suction nozzle tube.

[0011] A further improvement is that a guide plate is hinged to the end of the feeding channel away from the connecting port.

[0012] A further improvement is that both sides of the guide plate are provided with enclosures.

[0013] A further improvement is that the bottom of the feeding channel is provided with support legs, and at least two sets of support legs are provided.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. This utility model accommodates the suction tube through a guide channel and guides the suction tube through an inclined drop, allowing the suction tube to enter the feeding channel through the connecting port. During this process, the first arm moves at a constant speed under the drive of the motor, driving the actuating arm to rotate. Under the linkage of the second arm, the actuating arm moves the actuating rod to the left end of the suction tube along an arc path without touching the suction tube. Then, it pushes the suction tube to the right end for feeding. After the first suction tube at the connecting port is pushed away, the subsequent suction tubes in the guide channel pass through the connecting port into the feeding channel, repeating in sequence to achieve the effect of feeding at equal intervals. One suction tube is fed at a time, preventing overfeeding, making it convenient and more reliable to use.

[0022] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0023] Example 1

[0024] according to Figure 1 , 2 As shown in Figure 3, this embodiment proposes a feeding structure for a suction tube in the production of a packaging bag with a suction nozzle, including a feeding channel 1 and a guiding channel 2. One end of the feeding channel 1 is provided with a connecting port 3, and the guiding channel 2 is obliquely connected to the connecting port 3.

[0025] The bottom of the feeding channel 1 is provided with a bottom chamber 4 at one end, and a first support arm 5 is rotatably provided at one end of the front side of the bottom chamber 4. A second support arm 6 is rotatably provided at the other end of the front side of the bottom chamber 4. A toggle arm 7 is rotatably provided at the upper end of the first support arm 5. The upper end of the second support arm 6 and the middle end of the toggle arm 7 are hinged together. A toggle rod 8 is provided at the upper end of the inner side of the toggle arm 7. The toggle rod 8 is located above the feeding channel 1. A motor 10 is provided at one end inside the bottom chamber 4. The output end of the motor 10 is connected to the first support arm 5. In use, the suction tube 15 is accommodated through the guide channel 2 and guided by the inclined drop, so that the suction tube 15 enters the feeding channel 1 through the connecting port 3. The connecting port 3 and the leftmost end of the feeding channel 1 are left with a certain distance, so that the suction tube 15 and the leftmost end of the feeding channel 1 are separated by a certain gap, which facilitates the push of the actuating rod 8. During this process, the motor 10 drives the first arm 5 to move at a constant speed, driving the actuating arm 7 to rotate. Under the linkage of the second arm 6, the actuating arm 7 causes the actuating rod 8 to move around an arc path to the left end of the suction tube 15. During this process, it will not touch the suction tube 15. Then it pushes the suction tube 15 to the right end to feed the material. When the first suction tube 15 at the connecting port 3 is pushed away, the subsequent suction tubes 15 in the guide channel 2 pass through the connecting port 3 into the feeding channel 1. This process is repeated to achieve the effect of feeding at equal intervals, and one suction tube 15 is fed at a time, without feeding too many.

[0026] A material box 9 is provided on the rear side above the material guide channel 2, and a discharge port communicating with the material guide channel 2 is provided on the lower front side of the material box 9. The material box 9 is used to accommodate the suction tubes 15. The upper opening of the material box 9 is used to connect a pressurizing device, and the pressurizing device is used to push the suction tubes 15 downward. In use, the material box 9 accommodates the suction tubes 15, which fall one by one onto the material guide channel. Specifically, the pressurizing device is an electric telescopic rod and a pressure plate (not shown in the figure). The pressure plate extends into the material box 9 and pushes the auxiliary suction tubes 15 to discharge. The structure of the pressurizing device is existing technology.

[0027] A protective cover 11 is provided at the top of the feeding channel 1 away from the connecting port 3, and the protective cover 11 is integrally formed with the feeding channel 1. The diameter of the protective cover 11 is larger than the diameter of the suction tube 15. The protective cover 11 is used to guide the suction tube 15 and prevent the suction tube 15 from falling out.

[0028] The feeding channel 1 is hinged to a guide plate 12 at the end away from the connecting port 3, and both sides of the guide plate 12 are equipped with surrounding plates. In use, the angle of the guide plate 12 is adjusted to face the material receiving point of the heat sealing equipment. The first support arm 5 moves at a constant speed, driving the actuating arm 7 to rotate. Under the linkage of the second support arm 6, the actuating rod 8 first moves around an arc path to the left end of the suction tube 15. During this process, it will not touch the suction tube 15. Then, it pushes the suction tube 15 to the right end to feed the material. The suction tube 15 falls to the material receiving point of the heat sealing equipment through the guide plate 12.

[0029] Example 2

[0030] according to Figure 1 , 2 As shown in Figure 3, this embodiment proposes a feeding structure for a suction tube in the production of a packaging bag with a suction nozzle, including a feeding channel 1 and a guiding channel 2. One end of the feeding channel 1 is provided with a connecting port 3, and the guiding channel 2 is obliquely connected to the connecting port 3.

[0031] The bottom of the feeding channel 1 is provided with a bottom chamber 4 at one end, and a first support arm 5 is rotatably provided at one end of the front side of the bottom chamber 4. A second support arm 6 is rotatably provided at the other end of the front side of the bottom chamber 4. A toggle arm 7 is rotatably provided at the upper end of the first support arm 5. The upper end of the second support arm 6 and the middle end of the toggle arm 7 are hinged together. A toggle rod 8 is provided at the upper end of the inner side of the toggle arm 7. The toggle rod 8 is located above the feeding channel 1. A motor 10 is provided at one end inside the bottom chamber 4. The output end of the motor 10 is connected to the first support arm 5. In use, the suction tube 15 is accommodated through the guide channel 2 and guided by the inclined drop, so that the suction tube 15 enters the feeding channel 1 through the connecting port 3. The connecting port 3 and the leftmost end of the feeding channel 1 are left with a certain distance, so that the suction tube 15 and the leftmost end of the feeding channel 1 are separated by a certain gap, which facilitates the push of the actuating rod 8. During this process, the motor 10 drives the first arm 5 to move at a constant speed, driving the actuating arm 7 to rotate. Under the linkage of the second arm 6, the actuating arm 7 causes the actuating rod 8 to move around an arc path to the left end of the suction tube 15. During this process, it will not touch the suction tube 15. Then it pushes the suction tube 15 to the right end to feed the material. When the first suction tube 15 at the connecting port 3 is pushed away, the subsequent suction tubes 15 in the guide channel 2 pass through the connecting port 3 into the feeding channel 1. This process is repeated to achieve the effect of feeding at equal intervals, and one suction tube 15 is fed at a time, without feeding too many.

[0032] The bottom of the feeding channel 1 is provided with support legs 13, and there are at least two sets of support legs 13. The bottom of the support legs 13 is provided with fixing screw holes 14. In use, the support legs 13 can be fixed to different positions by means of bolts through the fixing screw holes 14, which is convenient for installation with heat sealing equipment.

[0033] The feeding structure for the suction tubes in this packaging bag production process accommodates the suction tubes 15 through the guide channel 2 and guides them via an inclined drop, allowing the suction tubes 15 to enter the feeding channel 1 through the connecting port 3. During this process, the motor 10 drives the first support arm 5 to move at a constant speed, driving the actuating arm 7 to rotate. Under the linkage of the second support arm 6, the actuating arm 7 causes the actuating rod 8 to move along an arc path to the left end of the suction tube 15 without touching it. Then, it pushes the suction tube 15 to the right end for feeding. After the first suction tube 15 at the connecting port 3 is pushed away, the subsequent suction tubes 15 in the guide channel 2 pass through the connecting port 3 into the feeding channel 1, repeating this process to achieve an evenly spaced feeding effect. One suction tube 15 is fed at a time, preventing overfeeding, making it convenient and reliable. Simultaneously, the fixing screw holes 14 on the support legs 13, along with bolts, allow for fixing to different positions, facilitating installation with heat-sealing equipment and making it more convenient.
