Description

Technical Field

[0001] This utility model relates to the field of self-heating packaging bag production technology, specifically to a production equipment for self-heating packaging bags. Background Technology

[0002] Self-heating packaging bags are packaging bags that generate heat independently through internal chemical reactions or physical principles. These bags are typically used for products that require temperature maintenance, such as ready-to-eat foods, medicines, and heating packs. They can provide a sustained and stable temperature without the need for an external power source or heating device.

[0003] During the production of self-heating packaging bags, three sides need to be heat-sealed, with one side left open to allow the heating element to be packed inside. Finally, the bags are sealed again. Some current self-heating packaging bag production equipment directly rolls up the heat-sealed self-heating packaging bags together during the production process. This causes workers to need to reposition the opening position when performing subsequent bagging work, which is inefficient and can easily increase the size error of self-heating packaging bags in the same batch.

[0004] Therefore, we have made improvements and proposed a production equipment for self-heating packaging bags. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model discloses a production equipment for self-heating packaging bags, comprising a base and a heat sealing machine. A pair of unwinding rollers are mounted on one side of the top of the base via a bracket, and a winding roller is mounted on the other side of the top of the base. The heat sealing machine is mounted on the top of the base near the winding roller. A tensioning mechanism is mounted on the top of the base at a position between the heat sealing machine and the pair of unwinding rollers. A cutting mechanism is mounted on the top of the base between the heat sealing machine and the tensioning mechanism. The cutting mechanism includes a second mounting seat, which is mounted on the top of the base near the heat sealing machine. The top of the second mounting seat has a second sliding groove, within which a second slider is slidably mounted. The top of the second slider has several perforated cones, and a second driving assembly is mounted within the second sliding groove.

[0007] As a preferred embodiment of the present invention, the second driving component includes a second screw, which is rotatably mounted in the second slide groove and passes through the bottom end of the second slider and is threadedly connected to the second slider.

[0008] As a preferred embodiment of this utility model, a second motor is installed at the bottom of the second slide groove, and the output end of the second motor is connected to the second screw drive via a coupling.

A first groove is provided on one side of the first mounting base, and a pair of first sliders are slidably mounted in the first groove. A pair of tensioning rollers are symmetrically mounted on one side of the pair of first sliders, and a first driving assembly is installed in the first groove.

[0010] As a preferred embodiment of the present invention, the first driving component includes a bidirectional screw, which is rotatably mounted in the first slide groove, and the bidirectional screw passes through the upper and lower ends of a pair of first sliders and is threadedly connected to the pair of first sliders.

[0011] As a preferred embodiment of this utility model, a first motor is mounted on the top of the first mounting base, and the output end of the first motor is connected to the bidirectional screw drive via a coupling.

A plurality of opening cones 604 are installed at the top of the second slider 603. The movement of the second slider 603 can drive the opening cones 604 to move together, so that the opening cones 604 can cut an auxiliary dotted line on the surface of the self-heating packaging bag. A second driving component is installed in the second sliding groove 602 to drive the movement of the second slider 603.

[0024] The second drive assembly includes a second screw 605, which is rotatably mounted in the second slide groove 602 and passes through the bottom end of the second slider 603 and is threadedly connected to the second slider 603.

[0025] The second motor 606 is installed at the bottom of the second slide 602, and the output end of the second motor 606 is connected to the second screw 605 via a coupling.

[0026] The second motor 606 drives the second screw 605 to rotate. Under the limiting action of the second slide groove 602, the second slider 603 moves and drives the opening cone 604 to move.

[0027] The tensioning mechanism 5 includes a first mounting base 501, which is mounted on one side of the top of the base 1. A first groove 502 is provided on one side of the first mounting base 501. A pair of first sliders 503 are slidably mounted in the first groove 502. A pair of tensioning rollers 504 are symmetrically mounted on one side of the pair of first sliders 503. A first drive assembly is installed in the first groove 502.

[0028] The first drive component drives a pair of first sliders 503 to move simultaneously toward or away from each other, thereby adjusting the tensioning effect of the tensioning roller 504.

[0029] The first drive assembly includes a bidirectional screw 505, which is rotatably mounted in the first slide groove 502 and passes through the upper and lower ends of a pair of first sliders 503 and is threadedly connected to the pair of first sliders 503.

[0034] Working principle: When using this self-heating packaging bag production equipment, the operator first loads the raw material of the self-heating packaging bag onto a pair of unwinding rollers 3, and pulls the raw material through the space between a pair of tensioning rollers 504 and below the heat sealing machine 2, connecting it to the take-up roller 4. Then, the operator turns on the first motor 506, which drives the bidirectional screw 505 to rotate. Under the limiting action of the first slide groove 502, a pair of first sliders 503 move and drive a pair of tensioning rollers 504 to move, so that the tensioning rollers 504 tension the raw material of the self-heating packaging bag. After adjustment, the operator... The operator opens the take-up roller 4 and the unwind roller 3. When the self-heating packaging bag raw material moves to below the heat sealing machine 2, the take-up roller 4 and the unwind roller 3 stop rotating. The heat sealing machine 2 heat seals the three sides of the self-heating packaging bag raw material. Then the second motor 606 is turned on, and the second motor 606 drives the second screw 605 to rotate. Under the limiting action of the second slide 602, the second slider 603 moves and drives the opening cone 604 to move, so that the opening cone 604 makes a hole on the surface of the self-heating packaging bag raw material near the heat sealing position, which facilitates the operator to perform subsequent positioning and processing.
