Description

Technical Field

[0001] This utility model relates to a bubble wrap trimming machine, belonging to the field of bubble wrap trimming technology. Background Technology

[0002] Bubble wrap, also known as air cushion film, bubble wrap, or bubble paper, is a chemical product widely used in the packaging industry. It is primarily made of high-pressure polyethylene with added whitening agents, opening agents, and other additives, and is extruded and vacuum-formed into a bubble-like product at a high temperature of approximately 230 degrees Celsius. A bubble wrap trimming machine is a specialized device for cutting bubble wrap, mainly used in the packaging industry.

[0003] Traditional bubble wrap trimming machines use fixed-position strip cutters to trim the edges of the bubble wrap. After a period of use, the cut edges become dull, requiring frequent adjustments to the position of the strip cutters. This results in high labor intensity for workers and consequently affects production efficiency. Utility Model Content

[0004] Based on the above background, the purpose of this utility model is to provide a bubble wrap trimming machine to solve the problems described in the background art.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0006] A bubble wrap trimming machine includes a base, a support column fixedly mounted on the top of the base, a support roller rotatably connected to the inner wall of the support column, an adjustable trimming mechanism, and a winding mechanism.

[0007] The adjustable trimming mechanism includes a support frame, a drive motor is fixedly installed on the inner wall of the support frame, a rotating shaft is rotatably connected to the outer wall of the support frame, the output shaft of the drive motor is fixedly connected to the rotating shaft, blades are fixedly installed on the outer wall of the rotating shaft, and a connecting block is fixedly installed at the end of the rotating shaft away from the support frame.

[0008] Preferably, a connecting sleeve is fixedly installed on the side of the connecting block away from the rotating shaft, a movable block is movably inserted into the inner cavity of the connecting sleeve, an annular trimming knife is fixedly installed at the end of the movable block, and a No. 3 bolt is threadedly connected to the connecting sleeve, with the threaded end of the No. 3 bolt movably connected to the outer wall of the movable block.

[0009] Preferably, a duct is fixedly installed on the outer wall of the support frame, with an opening at one end of the duct near the support frame and a wind guide hood fixedly connected to the other end of the duct away from the support frame.

[0010] Preferably, the adjustable trimming mechanism further includes a support frame, which is fixedly installed on the top of the base. A crossbeam is fixedly installed at the end of the support frame away from the base. An adjusting sleeve is slidably connected to the outer wall of the crossbeam. A No. 1 bolt is threadedly connected to the top of the adjusting sleeve, and the threaded end of the No. 1 bolt is movably connected to the top of the crossbeam.

[0011] Preferably, a vertical plate is slidably connected to the inner wall of the adjusting sleeve, and a No. 2 bolt is threadedly connected to the side of the adjusting sleeve. The threaded end of the No. 2 bolt is movably connected to the side of the vertical plate, and the vertical plate is fixedly installed on the top of the support frame.

[0012] Preferably, the winding mechanism includes a stand, which is fixedly installed on the top of the base. A winding motor is fixedly installed on the back of the stand, and a rotating disk is rotatably connected to the front of the stand. The output shaft of the winding motor is fixedly connected to the back of the rotating disk. An assembly base is fixedly installed on the front of the rotating disk.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] The adjustable trimming mechanism utilizes a ring-shaped trimming blade instead of the traditional strip blade. A drive motor rotates the rotating shaft, which in turn drives the ring-shaped trimming blade through a transmission system involving connecting blocks, connecting sleeves, and movable blocks. This continuously adjusts the cutting position of the ring-shaped trimming blade, avoiding the frequent manual adjustments required when using a single cutting position. This reduces maintenance frequency and improves production efficiency. Furthermore, the rotating shaft's rotation causes the blades to rotate synchronously, drawing air in through the notch and then outputting it to the surface of the ring-shaped trimming blade through the air guide shroud. This cooling process prevents excessive heat buildup at the cutting point, which could cause the bubble wrap to deform and become damaged due to high temperatures, thus ensuring the quality of the bubble wrap production.
