Description

Technical Field

[0001] This utility model relates to the field of center-sealing bag making machine technology, and more specifically, to a center-sealing cooler for center-sealing bag making machine. Background Technology

[0002] A center-seal bag making machine is a specialized piece of equipment used to produce center-seal bags. It is mainly used for packaging granular or powdery materials such as cement, chemical raw materials, fertilizers, and grains, and achieves continuous production through heat-sealing molding technology.

[0003] A search revealed that utility model patent CN205615067U discloses a center-seal cooler for a center-seal bag making machine. The cooler includes a wedge-shaped compressed air chamber with several air jet holes at the lower part of the wedge-shaped slope at the front. Air inlet pipes are located on both sides of the rear of the chamber, and air inlet hoses are fitted onto the inlet pipes. A support is located in the middle of the rear of the wedge-shaped compressed air chamber. This design boasts advantages such as simple structure, low investment, easy maintenance, low operating costs, and produces flat, beautiful, and flawless center-seal bags. However, the aforementioned patent has the following shortcomings: it can only cool one side of the sealing area, resulting in poor cooling performance; and the high temperature generated during cooling is difficult to dissipate. Therefore, we propose a center-seal cooler for a center-seal bag making machine. Utility Model Content

A support frame 2 is fixedly connected to the top of the two mounting brackets 1. A heat dissipation mechanism 3 is provided on the support frame 2. Telescopic boxes 4 are fixedly sleeved on both sides of the support frame 2. A brake motor 5 is fixedly installed at the end of the two telescopic boxes 4. The output shafts of the two brake motors 5 extend into the inner cavity of the telescopic box 4 and are fixedly connected to screws 6 through couplings. Square columns 7 are threaded onto the outer sides of the two screws 6. Triangular boxes 8 are fixedly connected to the ends of the two square columns 7. Multiple air blowing holes 9 are provided at the ends of the two triangular boxes 8. Blowers 11 are fixedly installed on both sides of the support frame 2. Air guide hoses 12 are fixedly connected to the output ends of the two blowers 11. The ends of the two air guide hoses 12 are fixedly sleeved into the inner cavities of the two triangular boxes 8.

[0022] In this embodiment, the square post 7 is provided with a screw hole that matches the screw 6, ensuring that the screw 6 and the square post 7 can be smoothly transmitted.

[0023] Specifically, please refer to Figures 1 and 2. The heat dissipation mechanism 3 includes an exhaust pump 16 fixedly installed on the top surface of the support frame 2. The input end of the exhaust pump 16 extends to the bottom of the support frame 2 and is fixedly connected to an air intake hood 17. The output end of the exhaust pump 16 is fixedly connected to an exhaust hose 18.

[0024] In this embodiment, the end of the exhaust hose 18 can be directly extended to the outside of the workshop to exhaust the hot air generated by cooling to the outside, thus preventing the temperature inside the workshop from rising.

[0025] Specifically, please refer to Figure 2. Two studs 13 are threaded onto the outer side of the mounting bracket 1. One end of the stud 13 extends into the inner cavity of the mounting bracket 1 and is fixedly connected to the compression plate 15. The other end of the stud 13 is fixedly connected to the knob 14.

[0026] In this embodiment, when the two mounting brackets 1 are fitted onto the frames on both sides of the center-sealing bag making machine, the screw 13 and the mounting bracket 1 drive the extrusion plate 15 to extrude the side of the frame of the center-sealing bag making machine through the threaded engagement, thereby installing the device on the center-sealing bag making machine.

[0027] Specifically, please refer to Figures 1 to 3. A control panel 19 is fixedly installed on the outside of the support frame 2. The control panel 19 is electrically connected to the exhaust pump 16, the brake motor 5, and the blower 11.

[0028] In this embodiment, the control panel 19 is used to control the exhaust pump 16, the brake motor 5, and the blower 11. At the same time, the power supply of the external device is used to power the control panel 19, the exhaust pump 16, the brake motor 5, and the blower 11. This is existing technology and will not be described in detail.

[0029] Specifically, please refer to Figure 3. Supporting balls 10 are respectively fitted on both sides of the end of the triangular box 8.

[0030] In this embodiment, the supporting ball 10 is used to support the middle sealing edge of the packaging bag so that the air blown out of the air hole 9 can cool the sealing area.

[0031] Specifically, please refer to Figure 3, where the inner wall of the telescopic box 4 and the outer side of the square column 7 are fitted together.

[0032] In this embodiment, the inner wall of the telescopic box 4 is used to limit the square column 7, so that the square column 7 can only move along the axial direction of the screw 6.

[0033] Working Principle: In use, first, install the two mounting brackets 1 on both sides of the center-sealing bag-making machine frame. The distance between the two mounting brackets 1 is manufactured to match the width of the center-sealing bag-making machine frame. Then, rotate the knob 14 to rotate the stud 13. The threaded engagement between the stud 13 and the mounting bracket 1 drives the extrusion disc 15 to extrude pressure onto the outside of the center-sealing bag-making machine frame, thus fixing the device onto the machine. Next, flip the packaging bag so that the sealing edge is upright. Simultaneously, start the two brake motors 5 to rotate the two screws 6. The threaded engagement between the two screws 6 and the two square columns 7 causes the two triangular boxes 8 to move closer together, bringing the support balls 10 at the ends of the two triangular boxes 8 into contact with the sealing edge of the packaging bag. The support balls 10 support the sealing edge of the packaging bag. Then, start the two blowers 11 to draw low-temperature external air through the two air ducts 12 to the two triangular boxes 8. The air inside the two triangular boxes 8 is blown from the air blowing holes 9 to both sides of the sealing edge of the packaging bag, thereby cooling the sealing edge of the packaging bag. Finally, the exhaust pump 16 is started to generate suction force in the suction hood 17, and the hot air generated by the blowing and cooling is extracted by the suction hood 17, and the hot air is introduced to the outside by the exhaust hose 18.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
