Technical Field

[0001] This utility model relates to the field of PE bag production technology, specifically to a heat sealing machine sealing device. Background Technology

[0002] In the production of PE bags, a blow molding device is usually used to blow PE material into PE cylinders, and the production of PE bags is achieved by cutting and sealing the PE cylinders.

[0003] Chinese patent document CN220031326U discloses a sealing device for producing PE bags. By setting up an exhaust sealing mechanism, a first cylinder drives the connecting seat to move down, so that the exhaust roller presses one end of the PE bag. Then, the drive motor drives the exhaust roller to move, expelling the gas in the PE bag. Then, a second cylinder drives the sealer to move down to seal the PE bag after exhaust. This allows multiple PE bags to be exhausted and sealed one by one, reducing the cost of use and effectively improving the performance.

[0004] In the above solution, the PE tube needs to be cut and the exhaust roller needs to be driven by a drive motor to move along the length of the moving PE bag from one end to the other so that the gas in the PE bag can be discharged before sealing, which reduces the processing efficiency of the PE bag.

[0019] Example 1 like Figure 1-3 As shown, the present invention proposes a heat sealing machine sealing device, which includes a housing 1, a working hole 6, an adjustment component and a heating component; There are two working holes 6, which are respectively located at the top and bottom middle of the housing 1. On both sides of the working holes 6 and at the top of the housing 1, there are exhaust components that extend towards the middle of the working holes 6 and move the gas inside the bag upward when in use. The number of adjustment components is two, and the two adjustment components are symmetrically installed inside the housing 1. The end of the adjustment components is provided with a pressing component for elastically pressing the bag body. The heating component is located in the middle of the adjusting component and inside the pressing component. It is used to contact the PE bag and heat and seal it during use by driving the adjusting component.

[0020] In this embodiment, the blow-molded PE cylinder is moved from the working hole 6 at the top of the shell 1 to the working hole 6 at the bottom of the shell 1. During the movement of the PE cylinder, two exhaust components extend to the middle of the working hole 6 and cooperate to clamp and roll the PE cylinder, causing the PE cylinder to stack. At the same time, the air inside the PE cylinder moves upward. When it moves to the inside of the shell 1, the two adjusting components drive the pressing components to adjust their positions and move the two pressing components relative to each other, thereby clamping the PE cylinder. Through continuous adjustment by the adjusting components, the two pressing components generate an interaction force to compress the pressing components. The adjusting components drive the heating components to contact the PE cylinder for heating and sealing. At the same time, the adjusting components are reset, so that the intermittently sealed PE cylinder is conveyed to the cutting process. The cutting process processes the PE cylinder into a PE bag with one open end, thereby improving the processing efficiency of the PE bag.

[0021] Example 2 like Figure 1 As shown, the heat sealing device for a heat sealing machine proposed in this utility model differs from that in Embodiment 1 in that the exhaust assembly includes a fixed plate 2, a first spring 4, and a pressure roller 5. The fixing plate 2 is set at the top of the housing 1 and located on one side of the working hole 6; The pressure roller 5 is set on the side of the fixed plate 2 and located at the edge of the working hole 6; The number of first springs 4 is at least two, and both first springs 4 are disposed between and connected to the fixed plate 2 and the pressure roller 5.

[0022] In an optional embodiment, a limiting rod 3 is provided on the other side of the fixed plate 2. One end of the limiting rod 3 passes through the fixed plate 2 and is inserted into the inner side of the first spring 4 and connected to the pressure roller 5. It is also slidably connected to the fixed plate 2. During use, the limiting rod 3 slides on the fixed plate 2 to limit the position of the pressure roller 5 and prevent the pressure roller 5 from causing the first spring 4 to bend.

[0023] In this embodiment, the pressure roller 5 is moved towards the center of the working hole 6 by the elastic force of the first spring 4, and the two pressure rollers 5 are arranged in a mutual squeezing manner. When the PE cylinder moves towards the inside of the housing 1 between the two pressure rollers 5, the pressure roller 5 rolls and contacts the PE cylinder, and the PE cylinder is stacked. At the same time, the air inside the PE cylinder is moved upward to avoid the air inside the PE cylinder causing misalignment of the PE cylinder during subsequent sealing.

[0024] Example 3 like Figure 2 As shown, the heat sealing device of this utility model is different from that of embodiment one in that the adjustment component includes a mounting plate 7, a connecting plate 8 and a linear driver 9. Mounting plate 7 is located at the inner edge of housing 1; The linear actuator 9 is mounted on the top of the mounting plate 7 and its extended end is arranged towards the middle of the housing 1; The connecting plate 8 is installed at the extended end of the linear driver 9.

[0025] In an optional embodiment, a slide rod 10 is provided on the side of the connecting plate 8 and on the side of the linear actuator 9, and a connecting block 13 is provided on the top of the mounting plate 7. The slide rod 10 is inserted into the middle of the connecting block 13 and is slidably connected to the connecting block 13. This is used to support both ends of the connecting plate 8 through the cooperation of the slide rod 10 and the connecting block 13 during use, thereby improving the stability of the connecting plate 8.

[0026] In this embodiment, the linear actuator 9 drives the connecting plate 8 to move towards the PE cylinder, so that the connecting plate 8 drives the pressing component to contact the PE cylinder and compress the pressing component. Then, the connecting plate 8 drives the heating component to move towards the PE cylinder, so that it contacts the PE cylinder and performs heating and sealing work. Through the repeated movement of the linear actuator 9, the heating component performs intermittent sealing work according to the preset size of the PE bag, thereby improving the processing efficiency of the PE bag.

[0027] Example 4 like Figure 3 As shown, the heat sealing device for a heat sealing machine proposed in this utility model differs from that in Embodiment 1 in that the pressing component includes a pressure plate 12, a support rod 14, and a second spring 15. The pressure plate 12 is disposed on the other side of the connecting plate 8. The pressure plate 12 can be disposed above and below the heating component to reduce the pressure points during the processing of the PE bag. There are multiple support rods 14, which are arranged on the side of the connecting plate 8 and have their ends pass through the connecting plate 8 and connected to the pressure plate 12, and are slidably connected to the connecting plate 8. The second spring 15 is sleeved on the outside of the support rod 14 and is located between the pressure plate 12 and the connecting plate 8 and connected to them.

[0028] In this embodiment, the linear actuator 9 drives the connecting plate 8 to move toward the PE cylinder, so that the connecting plate 8 contacts the pressure plate 12 with the PE cylinder through the second spring 15. When the two pressure plates 12 are in contact with one side of the PE bag, the linear actuator 9 drives the connecting plate 8 to move continuously, so that the two pressure plates 12 clamp the PE bag and generate an interaction force, so that the pressure plate 12 drives the support rod 14 to slide on the connecting plate 8 and compresses the second spring 15, so that the connecting plate 8 drives the heating component to contact the PE cylinder and heat and seal it, thereby improving the stability of the PE cylinder during sealing and preventing the PE cylinder from shifting.

[0029] Example 5 like Figure 3 As shown, the heat sealing device for a heat sealing machine proposed in this utility model differs from that in Embodiment 1 in that the heating component includes a heating plate 11 and a fixing block 17. The fixing block 17 is installed in the middle of the side of the connecting plate 8. The fixing block 17 is made of high temperature resistant insulating material (such as ceramic and mica). The heating plate 11 is installed on the side of the fixing block 17 and located in the middle of the side of the pressure plate 12 and is connected to the external electrical control system. The connection method between the heating plate 11 and the fixing block 17 is existing technology and is only shown in the figure. In use, a layer of Teflon PTFE cloth can be wrapped on the outside or a Teflon coating can be sprayed to prevent the molten PE from sticking to the heating plate 11 and ensure that the seal is flat and smooth.

[0030] In an optional embodiment, a through hole 16 is provided in the middle of the pressure plate 12. The size of the through hole 16 is adapted to the size of the fixing block 17. When the pressure plate 12 drives the second spring 15 to compress, the fixing block 17 drives the heating plate 11 to be placed inside the through hole 16 and in contact with the PE cylinder, so that the heating plate 11 can heat and seal the PE cylinder.

[0031] In this invention, the blow-molded PE cylinder is moved from the working hole 6 at the top of the shell 1 to the working hole 6 at the bottom of the shell 1. As the PE cylinder moves inward toward the shell 1, the spring force of the first spring 4 moves the pressure roller 5 toward the middle of the working hole 6, and the two pressure rollers 5 are arranged in a mutual squeezing manner. When the PE cylinder moves inward toward the shell 1 between the two pressure rollers 5, the pressure rollers 5 and the PE cylinder roll into contact, stacking the PE cylinder and moving the air inside the PE cylinder upward. At the same time, the linear actuator 9 drives the connecting plate 8 to move toward the PE cylinder, so that the connecting plate 8 contacts the pressure plate 12 with the PE cylinder through the second spring 15. When one side of the PE bag contacts the PE tube, the linear actuator 9 drives the connecting plate 8 to move continuously, causing the two pressure plates 12 to clamp the PE bag and generate an interaction force. This causes the pressure plate 12 to drive the support rod 14 to slide on the connecting plate 8, compressing the second spring 15. The connecting plate 8 then drives the fixing block 17 to move towards the PE tube, causing the fixing block 17 to drive the heating plate 11 to contact the PE tube and heat and seal it. At the same time, the linear actuator 9 is reset and the above processing steps for the PE tube are repeated, causing the heating plate 11 to intermittently seal the PE tube and convey it to the cutting process. The cutting process processes the PE tube into a PE bag with one end open, thus improving the processing efficiency of the PE bag.

[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
