Description

Technical Field

[0001] This utility model belongs to the technical field of bubble wrap for packaging, and specifically relates to an environmentally friendly bubble wrap cutting machine. Background Technology

[0002] Bubble wrap, also known as bubble paper or cushioning film, is a transparent plastic packaging material made of polyethylene. Its characteristic feature is that its surface is covered with evenly distributed air bubbles. These bubbles provide excellent cushioning protection, preventing damage to goods caused by collisions, vibrations, or compression during transportation or handling. Bubble wrap is widely used in the packaging of goods requiring shockproof protection, such as electronics, ceramics, glassware, furniture, and precision instruments. During production, bubble wrap typically needs to be cut to the appropriate packaging size, thus requiring a cutting machine.

[0003] Currently available bubble wrap cutting machines have limitations. During the production of bubble wrap, there are certain defects on both sides. These machines cannot simultaneously trim the edges during cutting, which affects the quality of the cut bubble wrap. Furthermore, existing bubble wrap cutting machines cannot be flexibly adjusted or used for continuous cutting operations. Utility Model Content

[0004] The purpose of this utility model is to provide an environmentally friendly bubble wrap cutting machine. It can trim the bubble wrap before cutting by setting an edge trimming component on one side of the fixed plate, and can also roll up the waste generated by the edge trimming. Through the cooperation of the cutting mechanism, the limiting rod and the spring, the device can cut continuously, and the cutting knife holder can also be flexibly adjusted.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] An environmentally friendly bubble wrap cutting machine includes a frame, a platform fixedly installed on the top of the frame, and a conveyor belt installed on the top of the platform;

[0007] A feeding mechanism is provided on one side of the platform, and a cutting mechanism is provided on the top of the conveyor belt;

[0008] The feeding mechanism includes a support and a trimming assembly. A material roller and a guide roller are provided on one side of the support. A fixing plate is fixedly installed at one end of the support. A first motor is fixedly installed on one side of the fixing plate through a mounting plate. The first motor drives the winding rod to rotate. A guide roller is rotatably installed inside the fixing plate.

[0009] The trimming assembly includes a mounting bracket, on which an adjusting screw is threaded. The adjusting screw drives a shaft to move via a slider, causing the shaft to drive the cutting disc to move synchronously.

[0010] The cutting mechanism includes a fixed platform, on the top of which a second motor and a transmission box are fixedly installed. The second motor drives the transmission box to rotate the rotating arm, which in turn drives the sliding frame to move vertically and reciprocally through the connecting arm. A limiting sleeve is sleeved on the outside of the sliding frame, and a cutting knife holder is abutted inside the limiting sleeve by a spring.

[0011] The fixed plate is fixedly installed on the frame, and two sets of brackets are provided. The material roller is rotatably installed between the two sets of brackets, and multiple guide rollers are provided, with multiple guide rollers rotatably installed on the brackets.

[0012] The mounting bracket is fixedly installed with the fixing plate, the shaft is rotatably installed on one side of the slider, and one end of the adjusting screw is rotatably installed with the slider.

[0013] The cutting disc is sleeved on the outside of the shaft, and a bolt is provided on one side of the cutting disc, which passes through the cutting disc and abuts against the shaft.

[0014] The sliding frame is slidably installed with the machine frame, the two ends of the limiting cylinder are sleeved on the surface of the sliding frame, the spring abuts between the cutting knife seat and the limiting cylinder, and a limiting rod is inserted into one side of the limiting cylinder.

[0015] The technical effects achieved by this utility model are as follows:

[0016] This invention features a mounting bracket installed on one side of a fixed plate, with a slider inside. Rotating an adjusting screw drives the slider, shaft, and cutting disc to move linearly, thus adjusting the distance between the fixed plate and the cutting disc. This design is suitable for bubble wrap of different thicknesses. Since the cutting disc is bolted to the shaft, the trimming dimensions can be flexibly adjusted. The feeding mechanism and conveyor belt work together to move the bubble wrap on the fixed plate. During this movement, the cutting disc trims the bubble wrap, and the waste generated is wound up by a first motor and a winding rod. Therefore, this device can simultaneously perform trimming and waste collection, improving the quality of the cut bubble wrap sheets.

[0017] This invention utilizes a second motor mounted on the top of a fixed platform. This second motor drives a rotating arm to rotate via a transmission box, causing the connecting arm to drive the sliding frame, the limiting cylinder, and the cutting knife holder in a vertical reciprocating motion. The reciprocating motion of the cutting knife holder connects the cutting pieces. Because a spring is installed inside the limiting cylinder, and the cutting knife holder is sleeved on the outside of the sliding frame and abuts against the spring, while the limiting rod limits the position of the limiting cylinder on the sliding frame, the cutting knife holder can be adjusted by adjusting the limiting cylinder. This allows the device to be flexibly applied to bubble wrap of different thicknesses. Attached Figure Description

[0025] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0026] like Figure 1-5 As shown, an environmentally friendly bubble wrap cutting machine includes a frame 1, a platform 2 fixedly installed on the top of the frame 1, and a conveyor belt 3 installed on the top of the platform 2.

[0027] A feeding mechanism 4 is provided on one side of the platform 2, and a cutting mechanism 5 is provided on the top of the conveyor belt 3;

[0028] The feeding mechanism 4 includes a bracket 41 and a trimming assembly 45. A material roller 42 and a guide roller 43 are provided on one side of the bracket 41. A fixing plate 44 is fixedly installed at one end of the bracket 41. A first motor 47 is fixedly installed on one side of the fixing plate 44 through a mounting plate 46. The first motor 47 drives the winding rod 48 to rotate. A guide roller 49 is rotatably installed inside the fixing plate 44.

[0029] See attached document Figure 1 , Figure 2 , Figure 3 and Figure 4 In this embodiment, the fixed plate 44 is fixedly installed with the frame 1, the bracket 41 is provided in two sets, the material roller 42 is rotatably installed between the two sets of brackets 41, and multiple guide rollers 43 are provided, with multiple guide rollers 43 rotatably installed with the bracket 41.

[0030] In the above embodiment, the top of the fixed plate 44 is located below one end of the conveyor belt 3. Therefore, under the action of the conveyor belt 3 and the guide roller 43, the bubble film can move vertically along the surface of the fixed plate 44 to the surface of the conveyor belt 3. When the bubble film moves on the surface of the fixed plate 44, it can be trimmed by the trimming assembly 45. The trimmed bubble film can be sent to the cutting mechanism 5 below the conveyor belt 3 for cutting.

[0031] Specifically, the trimming assembly 45 includes a mounting bracket 451, wherein an adjusting screw 453 is threaded inside the mounting bracket 451. Therefore, when the adjusting screw 453 is rotated, the adjusting screw 453 can drive the shaft 454 to slide linearly inside the mounting bracket 451 via the slider 452.

[0032] More specifically, the mounting bracket 451 is fixedly installed with the fixing plate 44, while the shaft 454 is rotatably installed on one side of the slider 452, and one end of the adjusting screw 453 is rotatably installed with the slider 452. Therefore, when the shaft 454 moves linearly, the cutting disc 455 can be driven to move synchronously through the shaft 454, thereby adjusting the distance between the shaft 454 and the fixing plate 44, so that the trimming assembly 45 can be used for trimming bubble wrap of different thicknesses.

[0033] It should be noted that since the cutting disc 455 is sleeved on the outside of the shaft 454, and a bolt is provided on one side of the cutting disc 455, and the bolt passes through the cutting disc 455 and abuts against the shaft 454, the position of the shaft 454 can be adjusted linearly on the surface of the cutting disc 455 by removing the bolt, thus making it suitable for trimming of different sizes.

[0034] See attached document Figure 1 and Figure 5 In this embodiment, the cutting mechanism 5 includes a fixed platform 51. A second motor 52 and a transmission box 53 are fixedly installed on the top of the fixed platform 51. The second motor 52 drives the transmission box 53 to rotate the rotating arm 54, so that the rotating arm 54 drives the sliding frame 56 to move vertically and reciprocally through the connecting arm 55. The sliding frame 56 is sleeved with a limiting cylinder 57. The inside of the limiting cylinder 57 is abutted against the cutting knife seat 58 by a spring 59.

[0035] In the above embodiment, the transmission box 53 can be driven to rotate the rotating arm 54 by starting the second motor 52. Since the rotating arm 54 is hinged to the sliding frame 56 through the connecting arm 55, the sliding frame 56 can be vertically reciprocated through the cooperation of the connecting arm 55 and the rotating arm 54.

[0036] Furthermore, the limiting cylinder 57 is sleeved on the surface of the sliding frame 56, and the spring 59 abuts between the cutting knife holder 58 and the limiting cylinder 57. At the same time, a limiting rod 6 is inserted into one side of the limiting cylinder 57. Therefore, the position of the limiting cylinder 57 on the surface of the sliding frame 56 can be limited by the limiting rod 6. Thus, by adjusting the limiting cylinder 57, the spring 59 can push the cutting knife holder 58 to adjust synchronously, so that the cutting knife holder 58 can be used for bubble wrap cuttings of different thicknesses.

[0037] As can be further explained, the blade is fixedly installed inside the cutting blade holder 58 by bolts. Therefore, by moving the bolts left, right, and down, the cutting machine can change different blades according to actual usage needs, so that the cutting machine is not only suitable for use with bubble wrap, thereby improving the practicality of the cutting machine.

[0038] The working principle of this utility model is as follows: the bubble film on the material roller 42 passes through the guide roller 43 and is fed to the top of the conveyor belt 3 along the surface of the fixed plate 44. A conveying rubber roller is installed at the top of the conveyor belt 3. Therefore, the bubble film is conveyed under the action of the conveyor belt 3 and the conveying rubber roller. In use, by rotating the adjusting screw 453, the slider 452 and the shaft 454 are moved, thereby adjusting the distance between the cutting disc 455 and the fixed plate 44 to a suitable position. Through the conveying of the bubble film, the cutting disc 455 trims the edges of the bubble film, and the trimming waste is... The guide roller 49 guides the material to the surface of the take-up bar 48 and starts the first motor 47 to take up the waste material. The trimmed bubble wrap is then sent to the bottom of the cutting knife holder 58 via the conveyor belt 3. The second motor 52 is started to drive the transmission box 53 to rotate the rotating arm 54. The rotating arm 54 drives the sliding frame 56 to move vertically and reciprocally via the connecting arm 55. At the same time, the sliding frame 56 drives the cutting knife holder 58 to move synchronously via the limiting cylinder 57 and the spring 59, thus realizing continuous cutting operation. The size of the cut pieces can be controlled simply by adjusting the speed of the second motor 52.

[0039] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
