Description

Technical Field

[0001] The utility model belongs to the technical field of airbag bag processing, and particularly relates to an airbag bag shaping device. Background Technique

[0002] The processing of airbag bags is completed by cutting the airbag base cloth. After that, two layers of airbag base cloth are folded and sewn through a sealing device to form an airbag bag. After the airbag bag is processed, heat sealing and shaping are required for the sewing part. Through heat sealing and shaping, a sealed welding line can be formed at the edge or joint of the airbag bag to ensure that the gas inside the airbag bag will not leak.

[0003] At present, the heat sealing operation of airbag bags is to place a heating block on the edge of the airbag bag for shaping manually. The processing efficiency of manual heat sealing and shaping is relatively low. In addition, heat sealing is performed by manual pressing, and the pressure may cause incomplete heat sealing, affecting the airtightness of the airbag bag. For this reason, an airbag bag shaping device is proposed. Content of the Utility Model

[0004] Based on this, it is necessary to provide an airbag bag shaping device to solve the above problems.

A transmission shaft one is connected to the output shaft of the motor, and a cam is installed on the transmission shaft one. A fixed plate is arranged inside the box body, and a positioning hole one and a positioning hole two are opened on the fixed plate. The transmission shaft passes through the upper and lower positioning hole one and is rotationally connected to the fixed plate for installation. A transmission shaft two is arranged on the positioning hole two, and a connecting piece two is arranged on the transmission shaft two. Connecting rods are arranged at both ends of the connecting piece two, and rotating shafts are arranged at both ends of the connecting rods.

[0007] Further, the connecting rod is rotationally connected to the connecting block one and the connecting block two through the rotating shaft.

[0008] Further, a first connection hole is provided on a side of the first connection block away from the second transmission shaft, and a second connection hole is provided on a side of the second connection block close to the second transmission shaft.

[0009] Further, the length of the first connection block is less than the distance between the two second connection holes on both sides.

[0010] Further, a side of the second connection block away from the second transmission shaft is slidably connected to the cam.

[0021] Please refer to Figure 1 , the present utility model provides an airbag bag shaping device, including a box body 10; a first mounting hole 101 is provided at the top of the box body 10, a second mounting hole is provided at the front end of the box body 10, a motor 11 is provided on the first mounting hole 101, the motor 11 is connected to the top of the box body 10, a first transmission shaft 111 is connected to the output shaft of the motor 11, and a cam 112 is mounted on the transmission shaft 111.

[0022] A fixing plate 12 is arranged inside the box body 10. A first positioning hole 121 and a second positioning hole 122 are formed on the fixing plate 12. The first transmission shaft 111 passes through the upper and lower first positioning holes 121 and is rotatably connected to the fixing plate 12 for installation. The cam 112 is arranged between the first positioning hole 121 and the second positioning hole 122.

[0023] A second transmission shaft 13 is arranged on the second positioning hole 122. Connecting pieces one 131 are arranged at both ends of the second transmission shaft 13. Both ends of the second transmission shaft 13 are rotatably connected to the second positioning hole 122 through the connecting pieces one 131. A connecting piece two 132 is arranged on the second transmission shaft 13. The connecting piece two 132 is rotatably connected to the second transmission shaft 13. Connecting rods 133 are arranged at both ends of the connecting piece two 132. Rotating shafts 134 are arranged at both ends of the connecting rods 133. One end of the connecting rod 133 is rotatably connected to the connecting piece two 132 through the rotating shaft 134.

[0024] Connecting blocks one 14 and connecting blocks two 15 are respectively arranged at the other ends of the two side connecting rods 133. A first connecting hole 141 is arranged on the surface of the connecting block one 14 away from the second transmission shaft 13.

[0025] A second connecting hole 151 is arranged on the surface of the connecting block two 15 close to the second transmission shaft 13. The length of the connecting block one 14 is less than the distance between the two side second connecting holes 151. The surface of the connecting block two 15 away from the second transmission shaft 13 is slidably connected to the cam 112.

[0026] By the rotation of the cam 112 contacting the connecting block two 15, the connecting block two 15 is pushed to approach the second transmission shaft 13 side. By the connecting block two 15 pressing the connecting rod 133 to rotate, the connecting block one 14 and the connecting block two 15 approach or move away from each other.

[0027] At the front end of the box body 10, there are a first heating block 16 and a second heating block 17. The heating surfaces of the first heating block 16 and the second heating block 17 are close to each other. On one side of the first heating block 16, there is a first telescopic sleeve 161.

[0029] The working principle and usage process of the present utility model are as follows: First, the rotation of the motor 11 drives the rotation of the first transmission shaft 111. When the first transmission shaft 111 rotates, it drives the rotation of the cam 112. The rotation of the cam 112 contacts the second connecting block 15 and pushes the second connecting block 15 closer to the side of the second transmission shaft 13. By pressing the connecting rod 133 to rotate through the second connecting block 15, the two side connecting rods 133 rotate around the rotating shaft 134, so that the first connecting block 14 and the second connecting block 15 approach or move away from each other. When the first connecting block 14 and the second connecting block 15 approach each other, the first telescopic rod 162 and the second telescopic rod 172 respectively pull the first heating block 16 and the second heating block 17 closer to each other, and heat-seal the airbag placed between the first heating block 16 and the second heating block 17.
