Description

Technical Field

[0001] This application relates to the field of bubble wrap production technology, and in particular to a bubble wrap tensioning device. Background Technology

[0002] As is well known, bubble wrap produced by bubble blowing machines is lightweight, flexible, and has good cushioning properties. It has been widely used in the packaging and transportation industry for the outer packaging of fragile, easily scratched, and easily damp items, or as a cushioning and protection material for box packaging, effectively ensuring the safety of packaged items.

[0003] For example, Chinese utility model patent with announcement number CN221190935U discloses a bubble film tensioning device. A connecting shaft is provided at the rear of the inner side of the support plate. Two connecting arms are provided on the connecting shaft. An installation shaft is provided between the two connecting arms. A tensioning roller is installed on the outside of the installation shaft. A threaded groove is provided on the outer wall of the tensioning roller. The input end of the reducer and the rotating end of the drive motor are concentrically connected. The output end of the reducer and the drive shaft are concentrically connected. The threaded grooves on both sides of the outer wall of the tensioning roller have opposite rotation directions. The installation shaft and the tensioning roller are rotatably connected. The connecting arms and the connecting shaft are rotatably connected.

[0004] Regarding the aforementioned related technologies, the inventors believe that the bubble wrap tensioning devices in the related technologies, due to the large number of protruding bubbles on the bubble wrap during use, result in insufficient tightness in the bubble wrap winding, thus reducing the winding quality of the bubble wrap.

[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0006] In order to solve the problem that the bubble wrap tensioning device in the related technology does not roll up the bubble wrap tightly enough due to a large number of protruding bubbles on the bubble wrap, thus reducing the rolling quality of the bubble wrap, this application provides a bubble wrap tensioning device.

[0007] The bubble wrap tensioning device provided in this application adopts the following technical solution:

[0008] A bubble wrap tensioning device includes a base plate, a side plate fixedly mounted on one side of the top of the base plate, a drive motor fixedly mounted on the outer wall of the side plate, a rotating shaft fixedly connected to the output shaft of the drive motor, the rotating shaft passing through the side plate and having a take-up roller sleeved on its outer side, and a moving groove formed in the middle of the side plate, a bidirectional lead screw rotatably mounted inside the moving groove, two sliders symmetrically threaded to the outer side of the bidirectional lead screw, an mounting shaft fixedly connected to the side wall of each of the two sliders, and a tensioning roller sleeved on the outer side of the mounting shaft.

[0009] Preferably, the side plate has a guide groove that communicates with the moving groove, and a guide block is fixedly installed on the side wall of the slider, the guide block sliding inside the guide groove.

[0010] Preferably, the top of the bidirectional lead screw passes through the top of the side plate and is fixedly connected to a turntable, and the turntable has an anti-slip groove in the circumferential direction.

[0011] Preferably, the tensioning roller is made of rubber.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] The device itself has a moving groove on the side plate, and is equipped with a bidirectional lead screw, slider, mounting shaft, and tension roller. This allows the bubble wrap to be wound around the two tension rollers in an S-shape or inverted S-shape. Rotating the bidirectional lead screw pushes the two sliders closer together, which in turn moves the two tension rollers closer together. This increases the contact area between the bubble wrap and the tension rollers, achieving the tensioning operation of the bubble wrap and ensuring the quality of the bubble wrap winding.

[0018] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0019] This application discloses a bubble wrap tensioning device, referring to... Figure 1-3The system includes a base plate 1, a side plate 2 fixedly installed on one side of the top of the base plate 1, a drive motor 3 fixedly installed on the outer wall of the side plate 2, a rotating shaft 4 fixedly connected to the output shaft of the drive motor 3, the rotating shaft 4 passing through the side plate 2 and having a take-up roller 5 sleeved on its outer side, and a moving groove 21 opened in the middle of the side plate 2, a bidirectional lead screw 22 rotatably installed inside the moving groove 21, two sliders 23 symmetrically threaded on the outer side of the bidirectional lead screw 22, and a mounting shaft 6 fixedly connected to the side wall of each slider 23, with a tension roller 7 sleeved on the outer side of the mounting shaft 6.

[0020] Here, the bubble wrap is wound in an S-shape or inverted S-shape around two tension rollers 7. When the bidirectional lead screw 22 is rotated, it can push two sliders 23 closer together. The sliders 23 drive the two tension rollers 7 closer together, thereby increasing the contact area between the bubble wrap and the tension rollers 7, and realizing the tensioning operation of the bubble wrap. At the same time, the end of the bubble wrap is wound around the take-up roller 5. When the drive motor 3 is started, the drive motor 3 can drive the rotating shaft 4 and the take-up roller 5 to rotate, and perform the take-up operation of the bubble wrap.

[0021] Reference Figure 1 The side plate 2 has a guide groove that communicates with the moving groove 21. The guide block 24 is fixedly installed on the side wall of the slider 23 and slides inside the guide groove.

[0022] The guide block 24 and guide groove are provided here to limit the movement of the slider 23.

[0023] Reference Figure 1 The top of the bidirectional lead screw 22 passes through the top of the side plate 2 and is fixedly connected to the turntable 221. The turntable 221 has anti-slip grooves in the circumferential direction.

[0024] Here, a turntable 221 is provided, and anti-slip grooves are opened and closed on the turntable 221 to facilitate the rotation of the bidirectional lead screw 22.

[0025] Reference Figure 1 The tension roller 7 is made of rubber.

[0026] By making the tension roller 7 with a rubber material, the friction between the tension roller 7 and the bubble film can be increased.

[0027] The implementation principle of the bubble wrap tensioning device in this application embodiment is as follows: When in use, the device is placed in a designated position and the power is turned on. Then, the bubble wrap is wound around the two tensioning rollers 7 in an S-shape or an inverted S-shape. When the bidirectional lead screw 22 is rotated, the bidirectional lead screw 22 can push the two sliders 23 to move closer to each other. The sliders 23 drive the two tensioning rollers 7 to move closer to each other, thereby increasing the contact area between the bubble wrap and the tensioning rollers 7, and realizing the tensioning operation of the bubble wrap. At the same time, the end of the bubble wrap is wound around the take-up roller 5. Then, the drive motor 3 is started. The drive motor 3 can drive the rotating shaft 4 and the take-up roller 5 to rotate, and perform the take-up operation of the bubble wrap.
