DETAILED DESCRIPTION

[0025] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] Reference Figure 1-Figure 6As shown, the utility model provides a balloon bag making device based on double-head heat sealing, which is used to heat-seal two pieces of balloon films together, including a conveying device 1, and a guide device 2 and a heat-sealing component 3 are sequentially arranged in the conveying direction of the conveying device 1. The guide device 2 includes a movable plate 22 and a lifting component 23 symmetrically arranged on both sides of the conveying device 1. The two movable plates 22 move synchronously along the width direction of the conveying device 1, and the two lifting components 23 can move up and down on their respective movable plates 22. A first pulley 221 is rotatably arranged on the side of the movable plate 22 close to the conveying device 1, and a first limiting belt 2211 is also sleeved on the first pulley 221. The lifting component 23 includes a lifting plate 231 that can move up and down, and a second pulley 2311 is rotatably arranged on the side of the lifting plate 231 close to the conveying device 1, and a second limiting belt 2312 is sleeved on the second pulley 2311. The first limiting belt 2211 and the second limiting belt 2312 can clamp the balloon film and move the balloon film along the conveying direction of the conveying device 1.

[0027] When the balloon film is fed into the device, the guide device 2 will be adjusted according to the width of the film to ensure that the balloon film can pass smoothly. Then, the first limiting belt 2211 and the second limiting belt 2312 will clamp the balloon film and move forward driven by the conveying device 1. When the balloon film reaches the heat sealing component 3, the heat sealing component 3 will heat seal the two pieces of balloon film, thereby completing the production of the balloon bag.

[0028] Several first pulleys 221 are arranged on the movable plate 22, two of which are arranged along the conveying direction of the conveying device 1. A second rotating driving member 222 for driving the first pulleys 221 to rotate is also fixed on the side of the movable plate 22 away from the conveying device 1, and the output end of the second rotating driving member 222 is connected to one of the first pulleys 221.

[0029] Several second pulleys 2311 are arranged on the lifting plate 231, two of which are arranged along the conveying direction of the conveying device 1. A third rotating driving member 2313 for driving the second pulley 2311 to rotate is also fixed on the side of the lifting plate 231 away from the conveying device 1. The third rotating driving member 2313 is connected to one of the second pulleys 2311.

[0030] A first telescopic driving member 24 for driving the lifting plate 231 to move up and down is further provided on a side of the moving plate 22 away from the conveying device 1 , and an output end of the first telescopic driving member 24 is connected to the lifting plate 231 .

[0031] When the balloon film is fed into the device, the balloon film is first clamped by the first limiting belt 2211 and the second limiting belt 2312. At this time, as the second rotating driving member 222 and the third rotating driving member 2313 are started, the first pulley 221 and the second pulley 2311 start to rotate, driving the first limiting belt 2211 and the second limiting belt 2312 to move forward along the conveying direction of the conveying device 1.

[0032] When the lifting plate 231 descends, the second limiting belt 2312 presses the balloon film onto the first limiting belt 2211. Since the second limiting belt 2312 and the first limiting belt 2211 have sufficient contact length with the balloon film, the contact area with the balloon film is increased. This structure allows the two balloon films to be pre-pressed, effectively preventing the balloon film from deflecting during the heat sealing process, thereby improving the pressing quality of the balloon film.

[0033] The guide device 2 includes an adjustment component 21 capable of driving two movable plates 22 to move synchronously. The adjustment component 21 includes a base plate 211 and a lead screw 213 arranged along the width direction of the base plate 211. The lead screw 213 is connected to the movable plate 22 by a thread. The adjustment component 21 also includes a first rotating drive member 212 fixed on the base plate 211. The output end of the first rotating drive member 212 is fixedly connected to the lead screw 213.

[0034] The first rotary drive member 212 is started to drive the lead screw 213 to rotate. Since the lead screw 213 is connected to the movable plate 22 by threads, as the lead screw 213 rotates, the two movable plates 22 will move inward synchronously along the length direction of the lead screw 213 until the required width is reached.

[0035] The heat sealing assembly 3 includes two lower heat sealers 31 respectively fixed at one end of the two movable plates 22, and the heat sealing assembly 3 also includes an upper heat sealer 32 that can move up and down. A plurality of lower heat sealing wheels 311 are arranged on the side of the lower heat sealer 31 close to the conveying device 1, and an upper heat sealing wheel 321 is also rotatably arranged on the side of the upper heat sealer 32 close to the conveying device 1. The upper heat sealing wheel 321 and the lower heat sealing wheel 311 clamp the upper and lower sides of the balloon film respectively.

[0036] When the balloon film enters the heat-sealing area, the upper heat-sealing wheel 321 and the lower heat-sealing wheel 311 clamp the upper and lower sides of the film respectively. As the upper heat-sealing wheel 321 and the lower heat-sealing wheel 311 rotate, the balloon film is heated and melted to form a heat-sealed seam. In this process, the quality and strength of the heat-sealed seam are ensured.

[0037] The lower heat sealing wheels 311 are arranged along the length direction of the lower heat sealer 31, and each lower heat sealing wheel 311 is connected to a first sprocket 312, and each first sprocket 312 is connected by a chain. A fourth rotating driving member 313 is also fixed to the lower heat sealer 31, and the output end of the fourth rotating driving member 313 is connected to a second sprocket 314, and the second sprocket 314 and one of the first sprockets 312 are connected by a chain.

[0038] The upper heat sealing wheels 321 are arranged along the length direction of the upper heat sealer 32, and each upper heat sealing wheel 321 is connected to a third sprocket 323, and each third sprocket 323 is connected by a chain. A fifth rotating driving member 322 is also fixed to the upper heat sealer 32, and a fourth sprocket 324 is connected to the output end of the fifth rotating driving member 322, and the fourth sprocket 324 is connected to one of the third sprockets 323 by a chain. A second telescopic driving member 33 for driving the upper heat sealer 32 to move up and down is also fixed to the side of the lower heat sealer 31 away from the conveyor 1, and the output end of the second telescopic driving member 33 is connected to the upper heat sealer 32.

[0039] The two heat sealing components 3 can heat seal both sides of the balloon film at the same time, which not only improves the heat sealing efficiency, but also enhances the air tightness of the edge and reduces the risk of air leakage. In addition, the lower heat sealing wheel 311 and the upper heat sealing wheel 321 adopt a synchronous rotation mode, so that the balloon film can be heat sealed continuously, further improving the heat sealing efficiency.

[0040] Working principle: When in use, first start the first rotating driving member 212, and the first rotating driving member 212 drives the lead screw 213 to rotate. The rotation of the lead screw 213 causes the two movable plates 22 to move synchronously and adjust to a predetermined position according to the size of the balloon film. Then, the balloon film is placed on the conveying device 1. Next, start the first telescopic driving member 24, and the first telescopic driving member 24 drives the lifting plate 231 to move downward, so that the second limiting belt 2312 is pressed on the balloon film. Then, start the third rotating driving member 2313 to drive the second pulley 2311 to rotate, and start the second rotating driving member 222 to drive the first pulley 221 to rotate. In this way, the balloon film starts to move under the drive of the first limiting belt 2211 and the second limiting belt 2312, and the conveying speeds of the first limiting belt 2211, the second limiting belt 2312 and the conveying device 1 are consistent. Since the second limiting belt 2312 and the first limiting belt 2211 have a sufficient length to contact the balloon film, the contact area with the balloon film is increased, so that the two balloon films are pre-pressed. This pressing effect effectively prevents the balloon film from deflecting during the heat sealing process, thereby improving the pressing quality of the balloon film. When the balloon film moves between the lower heat sealing wheel 311 and the upper heat sealing wheel 321, the fifth rotating driving member 322 is started. The fifth rotating driving member 322 drives the fourth sprocket 324 to rotate, thereby driving the upper heat sealing wheel 321 to rotate. At the same time, the fourth rotating driving member 313 drives the second sprocket 314 to rotate, thereby driving the lower heat sealing wheel 311 to rotate. The lower heat sealing wheel 311 and the upper heat sealing wheel 321 can be powered on to generate heat, and the two sides of the balloon film are heat-sealed together as the upper heat sealing wheel 321 and the lower heat sealing wheel 311 rotate.

[0041] The above embodiments only express one or several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the attached claims.
