Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection bag processing, and particularly relates to a thermoplastic sealing device for environmental protection bag processing. Background Art

[0002] After materials are placed inside an environmental protection bag, the opening of the environmental protection bag needs to be sealed through thermoplastic sealing technology, so as to achieve the purpose of storing in a packaging box. When materials are placed inside the environmental protection bag, the opening of the environmental protection bag is prone to bulging, resulting in wrinkles on the seal.

[0003] According to the "thermoplastic sealing device for environmental protection bag processing" with the Chinese patent publication number CN220615092U, it mainly describes that the thermoplastic device is moved to the processing position through a moving device. Subsequently, the telescopic rod above works, expands and contracts up and down, drives the thermoplastic plate on the fixed plate to work, and performs thermoplastic processing on the environmental protection bag. The clamping groove can place the docking socket above, enabling the environmental protection bag to be fully processed by the thermoplastic plate, ensuring the quality and efficiency of the work. During the process of sealing the packaging bag, placing the packaging bag horizontally has a chance of causing the materials inside the packaging bag to fall out. When sealing, it is necessary to manually pull both sides of the packaging bag near the bag opening, resulting in a relatively troublesome sealing process.

[0004] Therefore, a thermoplastic sealing device for environmental protection bag processing is proposed to solve the problem that when sealing the packaging bag, placing the packaging bag horizontally has a chance of causing the materials inside the packaging bag to fall out, and it is necessary to manually pull both sides of the packaging bag near the bag opening when sealing, resulting in a relatively troublesome sealing process.

Detailed implementation manners

[0016] The present utility model will be further described below with reference to the accompanying drawings.

[0017] Please refer to Figures 1-3An environmentally friendly bag processing thermoplastic sealing device shown in the figure includes a support plate 1. A conveyor belt 2 is rotatably connected between two support plates 1. A first motor is fixedly connected to one of the support plates 1. The output end of the first motor is fixedly connected to a first screw rod 3. A protrusion is threadedly connected to the first screw rod 3. When the first motor rotates, the protrusion and the first slider 4 can move relatively, so as to limit the sealing position of the packaging bag. The bottom side of the protrusion is fixedly connected to a first slider 4. A second motor is fixedly connected to one side of the protrusion. The output end of the second motor is fixedly connected to a bidirectional screw rod 5. Under the action of the second motor, the second slider 6 moves relatively away from the center of the first slider 4. At this time, the contact wheel 7 rolls relatively away from the center of the packaging bag, so that the sealing position of the packaging bag is in a flat state. The second sliders 6 are threadedly connected to both sides of the bidirectional screw rod 5 that are away from each other. A groove is formed on one side of the second slider 6, and a contact wheel 7 is rotatably connected in the groove. First electric push rods 8 are fixedly connected to the opposite sides of the two support plates 1. A positioning sleeve 9 is sleeved on the output end of the first electric push rod 8. A positioning rod is inserted into the positioning sleeve 9 and the positioning rod is threadedly connected to the output end of the first electric push rod 8. The first electric push rod 8 makes the positioning sleeve 9 and the clamping plate 10 move relatively away or close. When the clamping plates 10 move relatively close, the two sealing strips 13 contact the sealing position of the packaging bag and provide a thermoplastic sealing effect. A clamping plate 10 is fixedly connected to one side of the positioning sleeve 9. The clamping plate 10 is in an L-shaped structure. An adjusting rod 11 is rotatably connected to the shorter end of the clamping plate 10. A moving plate 12 is threadedly connected to the adjusting rod 11. A sealing strip 13 is fixedly connected to one side of the moving plate 12. Heat pipes 14 are uniformly fixedly connected to the clamping plate 10. The heat pipes 14 are connected to an external power supply through wires and conduct heat to the clamping plate 10 and the sealing strip 13.

[0018] Among them, an auxiliary rod 15 is movably inserted into the support plate 1. The auxiliary rod 15 is fixedly connected to one side of the clamping plate 10. By setting the auxiliary rod 15, the stability of the movement of the clamping plate 10 can be increased.

[0019] Among them, support strips 19 are fixedly connected to both the upper and lower sides of the sealing strip 13. The support strips 19 contact the clamping plate 10. By setting the support strips 19, the stability of the sealing strip 13 on the clamping plate 10 can be increased, and the contact area can be increased, which is convenient for heating the sealing strip 13.

[0020] Among them, an auxiliary plate 17 is fixedly connected to the output end of the second electric push rod 16. The second electric push rod 16 is fixedly connected to the opposite sides of the two support plates 1. By setting the second electric push rod 16, the auxiliary plate 17 can be driven to move relatively, and the environmentally friendly bag can be positioned at the center position on the conveyor belt 2.

[0021] Among them, the conveyor belt 2 contacts the spherical balls 18. The spherical balls 18 are rotatably embedded in the four sides of the bottom end of the auxiliary plate 17. By setting the spherical balls 18, the friction between the auxiliary plate 17 and the conveyor belt 2 can be reduced.

[0022] Working principle: Place the environmental protection bag filled with materials on the conveyor belt 2. When the environmental protection bag moves to one side of the second electric push rod 16, starting the second electric push rod 16 can make the two auxiliary plates 17 move relatively, and promote the packaging bag to move to the center of the conveyor belt 2. At this time, the conveyor belt 2 drives the packaging bag to move. When the packaging bag is between the two first sliders 4, start the first screw rod 3 to drive the two first sliders 4 to move relatively. Then the drive motor on the convex side makes the bidirectional screw rod 5 rotate and the second slider 6 move relatively to the center of the packaging bag, and makes the contact wheel 7 contact the sealing part of the packaging bag from the center of the packaging bag. At this time, the drive motor on the convex side drives the bidirectional screw rod 5 to turn over. At this time, the contact wheel 7 rotates and gradually moves to both side edges of the bag mouth of the sealed bag. At this time, the first electric push rod 8 extends, and promotes the edge sealing strip 13 to contact the bag mouth of the packaging bag. The heat pipe 14 heats up to make the clamping plate 10 and the edge sealing strip 13 heat up synchronously. At this time, the environmental protection bag can be heat-sealed by thermoplastic.

[0023] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and retouches can still be made, and these improvements and retouches should also be regarded as the protection scope of the present invention.

[0024] Other parts not detailed in the present invention belong to the prior art, so they will not be elaborated here.

[0025] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or equivalently replace some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
