Description

Technical Field

[0001] The utility model relates to the technical field of heat-sealing ironing knives, in particular to a cooling mechanism for a heat-sealing ironing knife. Background Technique

[0002] A heat-sealing ironing knife is a very commonly used tool. Its working principle is to place the ironing knife on the material with the edges already cut. Through the action of heat energy and pressure, the edges of the material are melted and deformed, so as to press out a flat edge. This process is particularly crucial in the production of heat-sealing lines by bag-making machines.

[0003] When the existing heat-sealing ironing knife is in use, due to the high ironing temperature of the heat-sealing ironing knife, during the ironing process of the heat-sealing line, the soft material of the heat-sealing line may adhere to the heat-sealing ironing knife due to excessive temperature, thus affecting the ironing effect of the heat-sealing ironing knife. And during the subsequent stretching process of the heat-sealing line, deformation is likely to occur.

[0004] In order to overcome the above defects, the prior art (Chinese patent with application number: 202022819917.8, application date: November 30, 2020) discloses an ironing cooling device for a bag-making machine. This ironing cooling device forms a cold air flow outside the ironing knife and between the ironing knife and the packaging bag film material by setting an ironing cooling device outside the ironing knife. On the one hand, it reduces the wrinkles of the packaging bag film material caused by heat convection conduction outside the ironing knife, avoids the medium recombination of the packaging bag film material, and reduces the change of the packaging bag film material. On the other hand, it avoids the adhesion problem of the packaging bag film material caused by the excessive temperature of the ironing knife, and improves the flatness and beauty of the packaging bag ironing.

[0005] Although the prior art can solve the problem of cooling the packaging bag film material, the cold air used by the ironing cooling device is not filtered. Usually, the cold air enters the cold air blower through the outside wind. Since there are impurity particles in the outside wind, it is directly used for refrigeration, which is likely to cause pollution to the packaging bag film material, and reduces the cooling effect on the packaging bag film material. Moreover, the angle of the blowing cannot be adjusted, reducing the practicability of the ironing cooling device.

[0006] Therefore, we propose a cooling mechanism for a heat-sealing ironing knife, which can well solve the above problems. Content of the Utility Model

[0007] The purpose of the utility model is to provide a cooling mechanism for a heat-sealing ironing knife, so as to solve the problem that in the prior art, when a cooling mechanism for a heat-sealing ironing knife on the current market is in use, the cold air used by the ironing cooling device is not filtered.

[0033] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0034] Please refer to Figures 1 - 8 , the present utility model provides the following technical solutions:

[0035] Embodiment 1: To solve the problem that when a cooling mechanism for a heat-sealing and hot-knife in the market is in use, the cold air used by the hot-pressing and cooling device is not filtered. Usually, the cold air enters the cold air blower through the external wind. Since the external wind contains impurity particles, it is directly used for refrigeration, which is likely to cause pollution to the packaging bag film material and reduce the cooling effect on the packaging bag film material. Reference can be made to the attached Figure 1 -attached Figure 3 、attached Figure 5 and attached Figure 7, including a bag-making machine housing 1. There are two hydraulic cylinder bodies 3 provided on the inner top wall of the bag-making machine housing 1. The output end of the hydraulic cylinder body 3 is fixedly installed with a base 4, and the bottom of the base 4 is fixedly installed with a heat-sealing and ironing knife body 5; it also includes: grooves 6 are opened on both sides of the heat-sealing and ironing knife body 5 inside the base 4. A fixing rod 7 is fixedly installed inside the groove 6. A rotating plate 8 is sleeved on the outer wall of the fixing rod 7. The bottom of the rotating plate 8 is fixedly installed with a blowing plate 9, and a plurality of blowing heads 10 are fixedly installed at the bottom of the blowing plate 9; an air inlet 2 is opened on the right side of the bag-making machine housing 1. A purification box 16 is fixedly installed at the rear inner part of the top of the bag-making machine housing 1. A cold air blower body 18 is fixedly installed at the rear inner part of the top of the bag-making machine housing 1, and the cold air blower body 18 is communicated with the purification box 16 through a connecting pipe. An air extraction pump body 19 is arranged inside the top of the bag-making machine housing 1. Both sides of the air extraction pump body 19 are fixedly connected with a communicating pipe 20. The left side of the communicating pipe 20 is fixedly installed with a hose 21, and the end of the hose 21 penetrates through the blowing plate 9. A sealing door is arranged at the back of the bag-making machine housing 1. Two filter plates 17 penetrate through the purification box 16. A fixing sleeve 22 is fixedly installed on the front of the filter plate 17. Fastening bolts penetrate through both sides of the fixing sleeve 22. The filter plate 17 is detachably connected to the purification box 16, and a filter screen is arranged inside the filter plate 17.

[0036] After the heat-sealing line to be processed is placed on the bag-making machine housing 1, the output end of the hydraulic cylinder body 3 drives the heat-sealing and ironing knife body 5 to move downward to melt and press the heat-sealing line. Then, in cooperation with an external control board, the air extraction pump body 19 and the cold air blower body 18 are started. Thus, external air enters the purification box 16 through the air inlet 2, and the air sequentially passes through the two filter plates 17 arranged in the purification box 16. Thus, the filter screen in the filter plate 17 filters the particulate impurities in the air, and the filtered air enters the cold air blower body 18 through the connecting pipe. Thus, the cold air blower body 18 operates to cool the air, and the cooled air enters the communicating pipe 20 and the hose 21 through the air extraction pump body 19 and is conveyed to the blowing plate 9. Thus, the plurality of blowing heads 10 blow the cold air in the blowing plate 9 onto the heat-sealing line after the subsequent melting and pressing are completed, which can cool the heat-sealing line after melting and pressing, prevent the heat-sealing line from sticking to the heat-sealing and ironing knife, and improve the resistance to deformation of the heat-sealing line during the subsequent stretching process. By manually opening the sealing door connected to the bag-making machine housing 1 and then pulling out each fastening bolt from the fixing sleeve 22 in sequence, each fixing sleeve 22 drives the filter plate 17 to be pulled outwards, so as to disassemble, replace or clean the filter plate 17.

[0037] Embodiment 2: The angles of the plurality of blowing heads 10 connected to the blowing plate 9 can be adjusted. For reference, please refer to Figure 1 - Attachment Figure 2 、Attachment Figure 4 - Attachment Figure 6 and Attachment Figure 8, two guide rods 13 are fixedly installed on the front of the base 4. A rotating shaft 11 is arranged on the front of the blowing plate 9. A connecting plate 12 is rotatably connected to the right side of the rotating shaft 11. The guide rod 13 penetrates through the inside of the connecting plate 12. A baffle 14 is fixedly connected to the front of the guide rod 13, and the baffle 14 is located in front of the connecting plate 12. Positioning bolts 15 penetrate through both sides of the baffle 14, and the ends of the positioning bolts 15 are inserted into the connecting plate 12. The rotating plate 8 is rotatably connected to the fixed rod 7. The rotating plate 8 is in close fit with the blowing plate 9. The number of blowing plates 9 is two, and the two blowing plates 9 are communicated through a conveying pipe. The connecting plate 12 is movably connected to the guide rod 13, and the connecting plate 12 is arranged in an arc structure.

[0038] According to the situation of the heat-sealing line, manually pull the corresponding connecting plate 12, so that the connecting plate 12 moves on the guide rod 13. Thus, during the movement of the connecting plate 12, the blowing plate 9 connected to the rotating shaft 11 is driven to rotate. During the rotation of the blowing plate 9, the rotating plate 8 is driven to rotate on the fixed rod 7 through the corresponding groove 6. After adjusting the appropriate angles of the several blowing heads 10 connected to the blowing plate 9, manually pass the positioning bolts 15 through the baffle 14 and insert them into the connecting plate 12, thereby fixing the blowing plate 9, which is convenient for adjusting the angles of the several blowing heads 10 connected to the blowing plate 9 and improving the practicability of the cooling mechanism.
