Description

Technical Field

[0001] This utility model relates to the technical field of hot-stamping devices, specifically to a hot-stamping device for food packaging bags. Background Technology

[0002] With the continuous development of technology, food packaging bag manufacturing equipment has achieved automated production line production. When the food packaging bags are hot-stamped, the packaging bags are transported by a conveyor belt and stop under the hot-stamping blade of the hot-stamping device. After the hot-stamping device hot-stamps the packaging bags, the conveyor belt continues to work, and the above operation is repeated to complete the hot-stamping of all food packaging bags.

[0003] Manual sealing can prevent air from escaping from the packaging bag, affecting the seal and subsequent conveying efficiency. In addition, existing automated equipment lacks dynamic positioning of the food, cannot adapt to the edge-sealing requirements of packaging bags of different heights, and the pressure control between the heating plate and the packaging bag is not precise, which can easily cause excessive compression or incomplete sealing.

[0004] Therefore, a hot-stamping device for food packaging bags is proposed. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a hot-stamping device for food packaging bags.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A hot-stamping device for food packaging bags includes a workbench, a controller, and a support frame. A placement platform is vertically mounted above the workbench. The support frame is fixed above the workbench and has a lifting component on it. The lifting component drives the placement platform to rise and fall. A driving component is installed on the first slide rail of the lifting component. The driving component drives two J-shaped limiting plates to move towards or away from each other. The limiting plates are equipped with a heating plate, a limiting component, a first pressure sensor, and a second pressure sensor.

[0008] Furthermore, the lifting component includes a first slide rail, a first motor, a reciprocating lead screw, and a first slider. The first slider is threadedly connected to the reciprocating lead screw, and the first slider is slidably adapted to the first slide rail. The reciprocating lead screw is connected to the main shaft end of the reciprocating lead screw, and the placement platform is connected to the first slider.

[0009] Furthermore, the driving component includes a second slide rail, a second motor, a bidirectional lead screw, and symmetrically arranged second sliders. The bidirectional lead screw is connected to the main shaft end of the second motor. The second slider is threadedly adapted to the two threaded grooves on the bidirectional lead screw. The second slider is slidably adapted to the second slide rail. The two limiting plates are respectively connected to one of the second sliders. The second slide rail is located on one side of the first slide rail.

[0010] Furthermore, the limiting component includes a telescopic rod, a spring, and a baffle. The spring is sleeved on the outside of the telescopic rod, and the baffle protrudes from the heating surface of the heating plate, forming a protective structure to prevent accidental contact.

[0011] Furthermore, a second pressure sensor is embedded inside the curved portion of the limiting plate, and a heating plate is installed inside the vertical plane portion of the plate, with the heating surface of the heating plate being coplanar with the detection surface of the first pressure sensor.

[0012] Furthermore, the controller integrates a timing module, and the first motor, the second motor, the heating plate, the first pressure sensor, and the second pressure sensor are electrically connected to the controller.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention uses a lifting component and a driving component to coordinate the movement of the placement platform and the J-shaped limiting plate. During the upward movement of the packaging bag, the curved part of the limiting plate dynamically limits the position of the food, ensuring that the hot edge is tightly attached to the food. The coplanar design of the heating plate and the first pressure sensor, combined with the spring buffer of the limiting component, achieves precise pressure control, avoids excessive squeezing, ensures a firm seal without damaging the material, effectively removes air, and improves sealing performance and conveying efficiency.

Therefore, they should not be construed as limitations on this utility model.

[0023] like Figure 1-3As shown, a hot-stamping device for food packaging bags includes a workbench 1, a controller 2, and a support frame 4. A placement platform 3 is vertically mounted above the workbench 1. The support frame 4 is fixed above the workbench 1 and has a lifting component 5. The lifting component 5 drives the placement platform 3 to rise and fall. A driving component 7 is installed on the first slide rail 501 of the lifting component 5. The driving component 7 drives two J-shaped limiting plates 6 to move towards or away from each other. The J-shaped limiting plates 6 can guide the food packaging bag. During its continuous rise, the J-shaped limiting plates 6 can limit the food inside the top of the food packaging bag, thus ensuring that the hot-stamping position is close to the food position and avoiding excessive air inside, which would affect subsequent conveying. The limiting plate 6 is equipped with a heating plate 9, a limiting component 8, a first pressure sensor 10, and a second pressure sensor 11. Specifically, the heating plate 9 can be an adjustable temperature model, and a temperature detection module is set in a suitable position to achieve precise temperature control. Since its temperature control method is not the main innovation of this technical solution, it will not be described in detail here.

[0024] like Figure 2 As shown, the lifting component 5 includes a first slide rail 501, a first motor 502, a reciprocating lead screw 503, and a first slider 504. The first slider 504 is threadedly connected to the reciprocating lead screw 503, and the first slider 504 is slidably adapted to the first slide rail 501. The reciprocating lead screw 503 is connected to the main shaft end of the reciprocating lead screw 503. The placement platform 3 is connected to the first slider 504. Specifically, the first motor 502 controls its forward and reverse rotation through the controller 2. When the placement platform 3 needs to be raised or lowered, the controller 2 sends a control signal to the first motor 502 according to a preset program or operation command, causing it to rotate forward or reverse. The main shaft of the first motor 502 is connected to the reciprocating lead screw 503. The rotation of the first motor 502 is converted into the linear motion of the first slider 504 through the reciprocating lead screw 503. The first slider 504 is connected to the placement platform 3, thereby driving the placement platform 3 to rise or fall. During the raising or lowering process, the highest and lowest positions of the placement platform 3 may be controlled by limit switches. When the placement platform 3 reaches the limit position, the limit switch is triggered. After receiving the signal, the controller 2 immediately stops the first motor 502 to prevent the placement platform 3 from exceeding the safe range. The alternative lifting component 5 can be an electric telescopic rod or other lifting structure to control the limit plate 6 for raising or lowering.

[0025] like Figure 2As shown, the driving component 7 includes a second slide rail 701, a second motor 702, a bidirectional lead screw 703, and symmetrically arranged second sliders 704. The bidirectional lead screw 703 is connected to the spindle end of the second motor 702. The second sliders 704 are threadedly fitted to the two threaded grooves on the bidirectional lead screw 703. The second sliders 704 are slidably fitted to the second slide rail 701. The two limiting plates 6 are respectively connected to one of the second sliders 704. The second slide rail 701 is located on one side of the first slide rail 501. Specifically, the controller 2 sends a signal as needed to make the second motor 702 rotate forward or backward, thereby driving the bidirectional lead screw 703 to rotate. The two threaded grooves of the bidirectional lead screw 703 are threadedly fitted to the two second sliders 704. When the second motor 702 drives the bidirectional lead screw 703 to rotate, the two second sliders 704 will move towards or away from each other, thereby driving the limiting plates 6 to perform clamping or loosening actions. The controller 2 can monitor the speed and position of the second motor 702 through a feedback mechanism (such as an encoder) to ensure the movement accuracy of the limiting plates 6.

[0026] like Figure 3 As shown, the limiting component 8 includes a telescopic rod 801, a spring 802, and a baffle 803. The spring 802 is sleeved on the outside of the telescopic rod 801, and the baffle 803 protrudes from the heating surface of the heating plate 9 to form an anti-accidental contact protection structure. Specifically, under the action of the baffle 803, the food packaging bag can be prevented from contacting the heating plate 9 in advance, thus preventing damage to it.

[0027] like Figure 3 As shown, a second pressure sensor 11 is embedded inside the curved portion of the limiting plate 6, and a heating plate 9 is installed inside its vertical plane portion. The heating surface of the heating plate 9 is coplanar with the detection surface of the first pressure sensor 10. Specifically, when the two limiting plates 6 approach each other, the two baffles 803 first come into contact, then the telescopic rod 801 retracts, the spring 802 is squeezed, and then the two heating plates 9 approach each other. Since the heating surface of the heating plate 9 is coplanar with the detection surface of the first pressure sensor 10, when the first pressure sensor 10 detects that the pressure value reaches the set value, it will send a signal to the controller 2. The controller 2 will then control the drive component 7 to stop working. During the process of the food packaging bag rising, the food inside the packaging bag will rise to a certain height and squeeze the curved portion of the limiting plate 6. When the second pressure sensor 11 detects that the pressure value reaches the set value, it will send a signal to the controller 2. The controller 2 will then control the lifting component 5 to stop working.

[0028] like Figure 1-3As shown, the controller 2 integrates a timing module, and the first motor 502, the second motor 702, the heating plate 9, the first pressure sensor 10, and the second pressure sensor 11 are electrically connected to the controller 2. Specifically, the first pressure sensor 10 and the second pressure sensor 11 can convert the detected pressure signal into an electrical signal and transmit it to the controller 2. Upon receiving the pressure signal, the controller 2 can coordinate the control of other components. At the start of the edge-pressing process, the controller 2 first controls the placement platform 3 to rise to a suitable position. When the second pressure sensor 11 detects that the pressure value has reached the set value, it drives the limit plate 6 to clamp the packaging bag and simultaneously starts the heating plate 9 to press the edge. The timing module precisely controls the pressing time to achieve the edge-pressing of the food packaging bag.

[0029] In summary: The placement platform 3 above the workbench 1 is lifted and lowered by the lifting component 5. Food packaging bags are placed on the placement platform 3. The first motor 502 of the lifting component 5 drives the first slider 504 to move along the first slide rail 501 via the reciprocating lead screw 503, thereby adjusting the height of the placement platform 3. During the lifting process, the food inside the packaging bag rises to a certain height and squeezes the curved part of the limiting plate 6. When the second pressure sensor 11 detects that the pressure value reaches the set value, it sends a signal to the controller 2. The controller 2 then controls the lifting component 5 to stop working. The driving component 7 drives the bidirectional lead screw 703 to rotate via the second motor 702, causing the two second sliders 704 to move towards each other along the second slide rail 701, thereby driving the two J-shaped limiting plates 6 to clamp the packaging bag; the heating plate 9 on the vertical plane is coplanar with the first pressure sensor 10. When the baffle 803 contacts, the spring 802 is compressed, the heating plate 9 contacts the packaging bag, and the first pressure sensor 10 feeds back a pressure signal; the controller 2 controls the lifting, clamping, and heating processes according to the pressure signal and the timing module, ensuring that the hot edge position is close to the food and avoiding excessive squeezing, thereby achieving precise temperature control and automated operation.
