Description

Technical Field

[0001] This utility model particularly relates to a bubble wrap cutting machine with a cutting component. Background Technology

[0002] Bubble wrap, a widely used cushioning packaging material, often requires rapid cutting according to the dimensions of goods during warehousing, logistics, and packaging operations. To improve efficiency, some devices equipped with simple cutting mechanisms have emerged on the market. The cutting components of these devices typically include a cutter head whose height can be adjusted via bolts. Its basic working principle is: loosen the bolts, move the cutter head up and down to the desired height, then tighten the bolts again, using the friction between the bolt head and the mounting base to fix the cutter head assembly.

[0003] During the cutting process, the cutter head is subjected to a reverse force from the bubble wrap, creating a continuous rotational torque. The simple friction of the bolts is insufficient to completely resist this torque, causing the cutter head assembly to easily rotate or slip slightly around the bolt axis when under stress. This rotation directly changes the preset cutting angle, resulting in incomplete cutting, burrs on the cut edges, or repeated cuts, severely affecting the cutting quality. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a bubble wrap cutting machine with a cutting component.

[0005] A bubble wrap cutting machine with a cutting assembly includes a frame, on which a winding bracket for winding bubble wrap is mounted, and an operating platform located on one side of the winding bracket for supporting and flattening the bubble wrap. A cutting assembly for cutting the bubble wrap is mounted above the operating platform. The cutting assembly includes slide bars symmetrically arranged on the frame, with sliders slidably mounted on the slide bars. A screw is threaded to the upper end of the slider, and a cutter head assembly for cutting the bubble wrap is connected to the lower end of the slider. The lower end of the screw is connected to the cutter head assembly. An anti-rotation platform is provided at the top of the screw, and an mounting groove for mounting the anti-rotation platform is provided at the upper end of the slider. An abutment is provided on the side of the slider, and a positioning notch adapted to the end of the abutment is provided on the anti-rotation platform. One end of the abutment passes through the slider and extends into the mounting groove to abut against the positioning notch.

[0006] Preferably, the slider also has a groove communicating with the mounting slot, and a rubber gasket is provided in the groove. The screw passes through the mounting slot and the rubber gasket in sequence and is then fixedly connected to the cutter head assembly.

[0007] Preferably, the slider includes an upper base and a lower base, the upper base having the mounting groove, and the cutter head assembly being fixedly connected to the screw.

A cutter head assembly for cutting bubble wrap is connected, and the lower end of the screw 43 is connected to the cutter head assembly; an anti-rotation platform 44 is provided at the top end of the screw 43, and an installation groove 45 for mounting the anti-rotation platform 44 is provided at the upper end of the slider 42. An abutment member 46 is provided on the side of the slider 42, and a positioning notch 47 adapted to the end of the abutment member 46 is provided on the anti-rotation platform 44. One end of the abutment member 46 passes through the slider 42 and extends into the installation groove 45 to abut against the positioning notch 47.

[0019] Furthermore, the slider 42 is provided with a groove 5 that communicates with the mounting groove 45. A rubber gasket 6 is provided in the groove 5. The screw 43 passes through the mounting groove 45 and the rubber gasket 6 in sequence and is then fixedly connected to the cutter head assembly.

[0020] Furthermore, the slider 42 includes an upper base 421 and a lower base 422. The upper base 421 is provided with the mounting groove 45, and the cutter head assembly is fixedly connected to the screw 43.

[0021] Furthermore, the cutter head assembly includes a mounting base 51 and a cutter head 52. The mounting base 51 is threadedly connected to the lower end of the screw 43, and the cutter head 52 is rotatably mounted on the mounting base 51.

[0022] Furthermore, a handshake portion 7 is provided on the lower base 422.

[0023] Furthermore, the upper base 421 and the lower base 422 are integrally formed.

[0024] The working principle of this utility model is as follows: A take-up bracket 2 is installed at one end of the frame 1 to hold and take up the bubble wrap roll. The operating platform 3 is fixed to the frame 1 and located on the output side of the take-up bracket 2. It provides a flat and stable surface for supporting and flattening the bubble wrap pulled from the roll. The cutting assembly is positioned above the operating platform 3 and is the core component for performing the cutting action.

[0025] As an embodiment 1, the slider 42 of this application can be composed of an upper base 421 and a lower base 422. The upper base 421 has a mounting groove 45 for accommodating the anti-rotation platform 44, and the lower base 422 is provided with a grip 7 for easy holding. The lower base 422 is threadedly connected to the cutter head assembly for easy assembly and maintenance. During installation, the lower end of the screw 43 is sequentially threaded to the upper base 421, the lower base 422, and the mounting seat 51 of the cutter head assembly. After assembly, the abutment 46 is screwed in so that one end of the abutment 46 extends into the mounting groove 45 and abuts against the positioning notch 47 on the anti-rotation platform 44. This design cleverly achieves circumferential locking of the screw 43, preventing it from changing in height due to the rotation of the screw 43 when cutting bubble wrap, thus ensuring the stability and consistency of the cutting depth.

[0026] In this technology, a rubber pad 6 is also provided inside the slider 42. A rubber pad 6 can also be provided inside the slider 42, which is embedded in the groove 5 that communicates with the mounting groove 45, through which the screw 43 passes. The rubber pad 6 is designed to effectively absorb cutting vibration and reduce operating noise.

[0027] During operation, the user pulls the bubble wrap from the take-up bracket 2, allowing its free end to lie flat across the surface of the operating platform 3. When the desired length is reached, one hand gently presses the film to position it on the operating platform 3. The other hand grips the handle 7 and applies lateral force. The entire cutter assembly then slides along the slide bar 41, and the lower cutter head 52 rolls and cuts the bubble wrap on the platform. After cutting, the user releases the handle 7 and pushes the cutter assembly back to its initial position, completing one work cycle. The cut bubble wrap can then be removed and used.

[0028] This invention transforms the traditional "friction locking" of bolts into an advanced "mechanical interlock" by having the end of the abutting part directly and rigidly press against the positioning notch on the anti-rotation platform. This design resists the rotational torque generated during the cutting process, preventing the possibility of slight rotation or slippage of the cutter head assembly around the screw axis, thus laying a solid foundation for stable and high-quality cutting.

[0029] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but the scope of protection is defined by the content of the claims.
