Description

Technical Field

[0001] This utility model relates to the field of desiccant packaging production technology, specifically a pneumatic heat sealing module. Background Technology

[0002] In the field of desiccant packaging production, traditional heat-sealing equipment faces numerous technical bottlenecks. Common heat-sealing structures often rely on a motor and cam to move the heat-sealing plate. However, this cam-motor structure requires the motor to accelerate and decelerate to drive the cam, and the cam mechanism itself has inertia, resulting in slow response and low heat-sealing efficiency. Furthermore, debris generated from the step-by-step heat-sealing and cutting process can contaminate the desiccant, failing to meet the stringent standards for pharmaceutical desiccants. Therefore, those skilled in the art have provided a pneumatic heat-sealing module to address the problems mentioned in the background. Utility Model Content

[0003] The purpose of this invention is to provide a pneumatic heat sealing module to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A pneumatic heat sealing module includes a vertical plate, a heat sealing frame fixedly connected to the side wall of the vertical plate, a sleeve rod fixedly connected to the inner side wall of the heat sealing frame, a slide rod slidably connected to the inner side wall of the sleeve rod, a movable plate fixedly connected to one end of the slide rod, two sets of heat sealing plates fixedly connected to the side wall of the movable plate, a cutter fixedly connected between the heat sealing plates, and a cylinder fixedly connected to the inner side wall of the heat sealing frame, with the movable end of the cylinder fixedly connected to the side wall of the movable plate.

[0006] Furthermore, a cover plate is fixedly connected between the heat sealing frame and the vertical plate, and a guide groove is fixedly opened on the surface of the cover plate.

[0007] Furthermore, a discharge trough for discharging materials is also fixedly connected to the side wall of the vertical plate.

[0008] Furthermore, the vertical plate sidewall is rotatably connected to a drive shaft and a driven shaft, and the output ends of the drive shaft and the driven shaft are respectively fixedly connected to a first guide wheel and a second guide wheel. The gap between the first guide wheel and the second guide wheel is used to guide the plastic-sealed bag.

[0009] Furthermore, a transmission gear is fixedly connected to the input end of the transmission shaft, and a driven gear is fixedly connected to the input end of the driven shaft, with the transmission gear and the driven gear meshing with each other.

[0010] Furthermore, a drive motor is fixedly connected to the side wall of the vertical plate, and the power output end of the drive motor is fixedly connected to the shaft end of the transmission gear.

[0011] By adopting the above technical solution

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The sliding fit between the sleeve rod and the slide rod provides stable guidance for the movable plate, ensuring the precise movement trajectory of the heat sealing plate and the cutter, and guaranteeing the heat sealing accuracy. The integrated design of the double heat sealer and the central cutter allows heat sealing and cutting to be completed simultaneously. A single action can form two sealing edges and separate the product, improving production efficiency. Power output is provided by a cylinder, which has a simple structure. The cylinder relies on compressed air as a power source. When the air supply is sufficient, it can quickly realize the reciprocating motion of the piston, with a fast response speed, and can perform high-speed reciprocating heat sealing.

[0014] 2. The meshing transmission between the drive gear and the driven gear ensures that the first guide wheel and the second guide wheel rotate synchronously in opposite directions, preventing the plastic bag from slipping or wrinkling during transportation and reducing the defect rate.

[0019] To make the technical means, creative features, achieved objectives and effects of this utility model easier to understand, the present utility model is further described below in conjunction with specific embodiments. In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0020] Please see Figures 1-3This utility model provides an embodiment of a pneumatic heat sealing module, including a vertical plate 1. A heat sealing frame 2 is fixedly connected to the side wall of the vertical plate 1. A sleeve rod 3 is fixedly connected to the inner side wall of the heat sealing frame 2. A sliding rod 4 is slidably connected to the inner side wall of the sleeve rod 3. A movable plate 5 is fixedly connected to one end of the sliding rod 4. Two sets of heat sealing plates 6 are fixedly connected to the side wall of the movable plate 5. A cutter 7 is fixedly connected between the heat sealing plates 6. A cylinder 8 is also fixedly connected to the inner side wall of the heat sealing frame 2. The movable end of the cylinder 8 is fixedly connected to the side wall of the movable plate 5. A cover plate 9 is fixedly connected between the heat sealing frame 2 and the vertical plate 1. A guide groove 10 is fixedly opened on the surface of the cover plate 9. A discharge groove 11 for discharging material is also fixedly connected to the side wall of the vertical plate 1. After the cylinder 8 is started, its movable end pushes the movable plate 5 along... The linear motion of the guide mechanism composed of the sleeve rod 3 and the slide rod 4 causes the heat-sealing plate 6 to contact the plastic bag and apply pressure. The high temperature generated by the heat-sealing plate 6 melts and seals the two edges of the plastic bag. At the same time, the cutter 7 completes the cutting in the center of the sealed area to form an independent package. The packaged product is automatically discharged through the discharge chute 11. The guide groove 10 on the cover plate 9 ensures that the plastic bag maintains a stable path during the conveying process and avoids deviation. The sliding cooperation between the sleeve rod 3 and the slide rod 4 provides stable guidance for the movable plate 5, ensuring the precise movement trajectory of the heat-sealing plate 6 and the cutter 7, and guaranteeing the heat sealing accuracy. The integrated design of the double heat sealer and the central cutter 7 allows the heat sealing and cutting to be completed simultaneously. Two sealing edges can be formed and the product can be separated in a single action, improving production efficiency.

[0021] In this embodiment, a drive shaft 12 and a driven shaft 13 are rotatably connected to the side wall of the vertical plate 1. The output ends of the drive shaft 12 and the driven shaft 13 are respectively fixedly connected to a first guide wheel 14 and a second guide wheel 15. The gap between the first guide wheel 14 and the second guide wheel 15 is used to guide the plastic-sealed bag. A drive gear 16 is fixedly connected to the input end of the drive shaft 12, and a driven gear 17 is fixedly connected to the input end of the driven shaft 13. The drive gear 16 and the driven gear 17 mesh with each other. A drive motor 18 is fixedly connected to the side wall of the vertical plate 1. The power output end of the drive motor 18 is fixedly connected to the shaft end of the drive gear 16. The drive motor 18 drives the driven gear 17 through the drive gear 16, so that the drive shaft 12 and the driven shaft 13 rotate synchronously in opposite directions, thereby driving the first guide wheel 14 and the second guide wheel 15 to transport the plastic-sealed bag to the heat-sealing area. The meshing transmission of the drive gear 16 and the driven gear 17 ensures that the first guide wheel 14 and the second guide wheel 15 rotate synchronously in opposite directions, avoiding slippage or wrinkles of the plastic-sealed bag during transportation and reducing the defect rate.

[0022] The drive motor 18 drives the driven gear 17 through the transmission gear 16, causing the transmission shaft 12 and the driven shaft 13 to rotate synchronously in opposite directions. This drives the first guide wheel 14 and the second guide wheel 15 to transport the plastic bag to the heat-sealing area. After the cylinder 8 is started, its movable end pushes the movable plate 5 to move linearly along the guide mechanism composed of the sleeve rod 3 and the slide rod 4, so that the heat-sealing plate 6 contacts the plastic bag and applies pressure. The high temperature generated by the heat-sealing plate 6 melts and seals the two edges of the plastic bag. At the same time, the cutter 7 completes the cutting in the center of the sealing area to form an independent package. The packaged product is automatically discharged through the discharge chute 11. The guide groove 10 on the cover plate 9 ensures that the plastic bag maintains a stable path during the transportation process and avoids deviation.

[0023] The sliding engagement of the sleeve rod 3 and the slide rod 4 provides stable guidance for the movable plate 5, ensuring the precise movement trajectory of the heat-sealing plate 6 and the cutter 7, and guaranteeing heat-sealing accuracy. The integrated design of the double heat sealer and the central cutter 7 allows heat sealing and cutting to be completed simultaneously. A single action can form two sealing edges and separate the product, improving production efficiency. Power output is provided by the cylinder 8, which has a simple structure. The cylinder 8 relies on compressed air as a power source. When the air supply is sufficient, it can quickly realize the reciprocating motion of the piston, with a fast response speed, enabling high-speed reciprocating heat sealing. The meshing transmission of the transmission gear 16 and the driven gear 17 ensures that the first guide wheel 14 and the second guide wheel 15 rotate synchronously in opposite directions, preventing the plastic bag from slipping or wrinkling during transportation and reducing the defect rate.

[0024] This specification describes embodiments, but not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
