Description

Technical Field

[0001] This utility model relates to the field of packaging bag production technology, and in particular to a dispensing machine for packaging bag production. Background Technology

[0002] Packaging bags are bags used to package various items. They are widely used in daily life and industrial production. During the production of packaging bags, a dispensing machine is used to apply glue to the edges of the packaging bags. By applying glue, the various parts of the packaging bag can be firmly bonded together to ensure the integrity of the packaging.

[0003] As disclosed in Utility Model No. CN217774616U, a dispensing machine for packaging bag production includes a support base. A conveyor table is fixedly mounted on the top surface of the support base. A groove is formed on the top surface of the conveyor table, and multiple conveyor rollers are evenly distributed within the groove. A conveyor belt is mounted on the surface of each conveyor roller. Support rods are symmetrically and vertically mounted on both sides of the conveyor table, and a slide rail is provided between the support rods. A slider is slidably mounted at the bottom end of the slide rail, and a cylinder is mounted at the bottom end of the slider. A protective cover is mounted at the bottom end of the cylinder, and a glue dispensing tube is installed inside the protective cover. The bottom end of the glue dispensing tube is mounted on a glue dispensing head. In this utility model, the conveyor rollers on the conveyor table drive the conveyor belt to move, and the conveyor belt transports the packaging bags, thereby improving the efficiency of gluing the packaging bags and reducing the burden on the workers. Furthermore, a heating strip inside the protective cover can prevent the glue in the glue dispensing tube from freezing, thus preventing the glue dispensing tube from becoming difficult to separate from the glue dispensing head. However, this technical solution has the problem that the packaging bag is relatively small in weight during application, and the packaging bag is easy to move during dispensing, which affects the dispensing accuracy. There is also a technical problem that the packaging bag cannot be pressed and stabilized during dispensing to ensure the dispensing quality. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a dispensing machine for packaging bag production, which can solve the technical problems of small packaging bag weight, easy movement of packaging bag during dispensing affecting dispensing accuracy, and inability to press and stabilize packaging bag during dispensing to ensure dispensing quality.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a dispensing machine for packaging bag production, including a base plate, a groove at the top of the base plate, a conveyor platform between the two ends of the groove, a frame at the middle of the top of the base plate, an electrical control box at the front end of the frame, a material box at the front end of the top of the frame, a lifting cylinder at the middle of the top of the frame, a lifting seat at the bottom of the lifting cylinder, a dispensing head at the middle of the bottom of the lifting seat, a dispensing pump at the middle of one side of the top of the frame, a connecting pipe at the input end of the dispensing pump, a conveying hose at the output end of the dispensing pump, stabilizing cylinders at both ends of the bottom of the lifting seat, a telescopic rod inserted into the bottom of the stabilizing cylinder, a connecting piece inside the stabilizing cylinder at the top of the telescopic rod, a compression spring at the top of the stabilizing cylinder, a stabilizing pressure plate at the bottom of the telescopic rod, and limit components on both sides of the top of the groove.

[0006] As a preferred embodiment of this utility model, the stabilizing cylinder is symmetrically arranged at the bottom end of the lifting seat, and the bottom end of the compression spring and the bottom end of the connecting piece are fixedly connected.

[0007] As a preferred technical solution of this utility model, one side of the connecting pipe penetrates the bottom of the rear end of the material box and extends into it, the bottom end of the conveying hose is fixedly connected to the top of the dispensing head, and the conveying hose and the dispensing head are connected.

[0008] In a preferred embodiment of this invention, the lifting seat is parallel to the top surface of the conveyor table, and the dispensing head is perpendicular to the bottom surface of the lifting seat.

[0009] As a preferred technical solution of this utility model, the limiting component is a fixed vertical plate, which is set on both sides of the top end of the trough. A rotating shaft is set above the conveyor table inside the fixed vertical plate, and a limiting pressure roller is set outside the rotating shaft.

[0010] As a preferred embodiment of this utility model, the fixed vertical plates are symmetrically arranged at both ends of the top of the trough, and the rotating shafts are arranged at equal intervals on the inner side of the fixed vertical plates, with the rotating shafts parallel to the top surface of the conveyor table.

[0011] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0012] 1. By setting clamping and stabilizing components at both ends of the bottom of the lifting seat, when the lifting seat is pushed down by the lifting cylinder and the dispensing head is lowered to dispense the packaging bag, the stabilizing cylinder also lowers. At the same time, the compression spring pushes the telescopic rod and the stabilizing pressure plate to lower and clamp the packaging bag. As the lifting seat descends and the compression spring is compressed, it can avoid excessive pressure on the stabilizing pressure plate from damaging the conveyor table. Thus, the packaging bag can be clamped and stabilized during the dispensing process to ensure the dispensing accuracy. It is highly feasible.

[0013] 2. By setting limit components on both sides of the top of the tank, the limit pressure rollers limit the packaging bags in the conveying process when the packaging bags are conveyed by the conveyor table. At the same time, the rotating shaft can make the limit pressure rollers rotate in the opposite direction to the conveying direction of the packaging bags, thereby preventing the packaging bags from curling up and folding during the conveying process, which would cause misalignment of the dispensing and thus further ensure the dispensing quality of the dispensing machine.

[0019] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this utility model. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0020] Example

[0021] Please refer to Figure 1-4 As shown, this utility model provides a dispensing machine for packaging bag production, including a base plate 1, a groove 2 at the top of the base plate 1, a conveyor table 13 between the two ends of the groove 2, and packaging bags to be dispensed via the conveyor table 13. A frame 3 is located at the middle of the top of the base plate 1, an electrical control box 4 is located at the front of the frame 3, a material box 7 is located at the front of the top of the frame 3, a lifting cylinder 9 is installed at the middle of the top of the frame 3, a lifting seat 8 is located at the bottom of the lifting cylinder 9, the lifting seat 8 is parallel to the top surface of the conveyor table 13, and a dispensing head 16 is located at the middle of the bottom of the lifting seat 8, the dispensing head 16 is perpendicular to the bottom surface of the lifting seat 8. A dispensing pump 10 is installed in the middle of one side. The input end of the dispensing pump 10 is provided with a connecting pipe 15. One side of the connecting pipe 15 passes through the bottom of the rear end of the material box 7 and extends into it. The output end of the dispensing pump 10 is provided with a conveying hose 11. The bottom end of the conveying hose 11 is fixedly connected to the top of one side of the dispensing head 16, and the conveying hose 11 and the dispensing head 16 are connected. After the optical positioning camera on the dispensing machine locates the packaging bag being conveyed to the bottom of the dispensing head 16, the height of the dispensing head 16 is positioned by the lifting cylinder 9. Then, the dispensing pump 10 is started to draw the glue through the connecting pipe 15 and convey it to the dispensing head 16 through the conveying hose 11 and output the dot at a specific position on the packaging bag.

[0022] As a further implementation of this embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, stabilizing cylinders 12 are provided at both ends of the bottom of the lifting seat 8. The stabilizing cylinders 12 are symmetrically arranged at the bottom of the lifting seat 8. A telescopic rod 20 is inserted into the bottom of the inside of the stabilizing cylinder 12. A connecting piece 19 is provided inside the stabilizing cylinder 12 at the top of the telescopic rod 20. A compression spring 18 is provided at the top of the inside of the stabilizing cylinder 12. A stabilizing pressure plate 17 is provided at the bottom of the telescopic rod 20. When the lifting seat 8 descends and drives the dispensing head 16 to descend to perform dispensing processing on the packaging bag, the stabilizing cylinder 12 descends accordingly. The bottom end of the compression spring 18 and the bottom end of the connecting piece 19 are fixedly connected. The compression spring 18 pushes the telescopic rod 20 and the stabilizing pressure plate 17 to descend and press and stabilize the packaging bag, thereby achieving the effect of pressing and stabilizing the packaging bag during dispensing processing to ensure dispensing accuracy.

[0023] When the lifting cylinder 9 pushes the lifting seat 8 to descend, it drives the dispensing head 16 to descend and perform dispensing processing on the packaging bag. The stabilizing cylinder 12 descends accordingly. At the same time, the compression spring 18 pushes the telescopic rod 20 and the stabilizing pressure plate 17 to descend and press and stabilize the packaging bag. As the lifting seat 8 descends, the compression spring 18 is compressed to avoid excessive downward pressure on the stabilizing pressure plate 17 and damage to the conveyor table 13. In this way, the packaging bag can be pressed and stabilized during the dispensing process.

[0024] As a further implementation of this embodiment, such as Figure 1 , Figure 2 and Figure 4 As shown, limit components are provided on both sides of the top of the tank 2. The limit components fix vertical plates 5. The fixed vertical plates 5 are set on both sides of the top of the tank 2. The fixed vertical plates 5 are symmetrically arranged at both ends of the top of the tank 2. A rotating shaft 14 is provided above the conveyor table 13 inside the fixed vertical plate 5. The rotating shaft 14 is arranged at equal intervals inside the fixed vertical plate 5. The rotating shaft 14 is parallel to the top surface of the conveyor table 13. A limit pressure roller 6 is provided outside the rotating shaft 14. When the packaging bag is conveyed by the conveyor table 13, the limit pressure roller 6 limits the packaging bag in the conveying process from above. The rotating shaft 14 can make the limit pressure roller 6 rotate in the opposite direction to the conveying direction of the packaging bag, thereby avoiding the packaging bag from curling up and folding during the conveying process, which would cause misalignment of the glue dispensing, thereby further ensuring the glue dispensing quality of the glue dispensing machine.

[0025] When the packaging bag is conveyed by the conveyor table 13, the limiting pressure roller 6 limits the packaging bag in the conveying process from above. At the same time, the rotating shaft 14 allows the limiting pressure roller 6 to rotate in the opposite direction to the conveying direction of the packaging bag, thereby preventing the packaging bag from curling up and folding during the conveying process, which would cause misalignment of the glue dispensing and thus further ensure the glue dispensing quality of the glue dispensing machine.

[0026] Specific working principle:

[0027] When using the dispensing machine, the dispensing machine operation program is first preset through the electrical control box 4. After starting the dispensing machine, the packaging machine is conveyed through the conveyor table 13. At the same time, the limiting pressure roller 6 limits the packaging bag in the conveying process from above. Meanwhile, the rotating shaft 14 allows the limiting pressure roller 6 to rotate in the opposite direction to the conveying direction of the packaging bag, thereby preventing the packaging bag from curling up during the conveying process. Then, the optical positioning camera on the dispensing machine is used to position the packaging bag below the dispensing head 16. The height of the dispensing head 16 is then positioned by the lifting cylinder 9. At the same time, the stabilizing cylinder 12 descends and pushes the telescopic rod 20 and the stabilizing pressure plate 17 to descend and press and stabilize the packaging bag through the compression spring 18. As the lifting seat 8 descends, the compression spring 18 is compressed to prevent the stabilizing pressure plate 17 from being damaged by excessive downward pressure. This can press and stabilize the packaging bag during the dispensing process. Then, the dispensing pump 10 is started to draw glue through the connecting pipe 15 and deliver it to the dispensing head 16 through the conveying hose 11 and output it at a specific position on the packaging bag, thereby performing continuous, stable and precise dispensing operation on the packaging bag.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
