Description

Technical Field

[0001] This application relates to the technical field of heat insulation cotton production, and particularly to a heat insulation cotton cutting device. Background Art

[0002] Broadly speaking, cotton products that can achieve heat insulation effects are collectively referred to as heat insulation cotton. Heat insulation cotton has the characteristics of high temperature resistance, non-flammability, and low thermal conductivity. Currently, heat insulation cotton widely used in industry is processed and produced using glass fiber as the material, such as fiberglass cotton and glass wool. Such products can be further processed by laminating aluminum foil and fiberglass cloth to make their uses more extensive. When producing heat insulation cotton, it is necessary to perform special-shaped cutting operations on heat insulation cotton of a certain specification so that the heat insulation cotton can adapt to different-shaped pasting parts.

[0003] Currently, a Chinese utility model patent application with a publication date of October 31, 2023, and a publication number of CN219924905U provides a heat insulation cotton cutting device, including a cutting machine body, an operation board, a moving gantry, a laser cutting head, and a fixing mechanism. In this utility model, a fixing mechanism is provided at the upper end of the cutting machine body. When the air cylinder is started, the air cylinder pushes the slider to move downward under the guidance of the slide rail, driving the pressing plate fixed to its bottom end to approach the bottom plate, thereby fixing the heat insulation cotton between the pressing plate and the bottom plate, achieving rapid fixation of the heat insulation cotton, avoiding displacement of the heat insulation cotton and causing inconsistent dimensions, thereby improving the cutting accuracy of the heat insulation cotton and the qualified rate of the finished heat insulation cotton products. By starting the motor, it drives the gear to rotate, and then drives the gear to move on the rack. And through the cooperation of the groove at the bottom end of the assembly body and the slide rail at the top end of the cutting machine body, the fixing mechanism slides parallelly at the top end of the cutting machine body, thereby achieving the purpose of being able to flexibly fix heat insulation cotton of different lengths and improving the flexibility of use of the fixing mechanism.

[0004] In a heat insulation cotton cutting device in the related art, since heat insulation cotton is often made of loose foamed cotton, when cutting the heat insulation cotton, fine heat insulation cotton debris will be generated at the cut, and these debris will float into the air around the device, causing environmental pollution. Workers inhaling these debris will also cause damage to the human body. Summary of the Utility Model

[0005] The embodiments of this application provide a heat insulation cotton cutting device, which can improve the technical problem that the debris generated during the cutting of heat insulation cotton in the related art will cause air pollution.

[0007] In the above technical solution of the embodiment of the present application, at least the following technical effects are achieved: When the device works, after the positioning mechanism drives the cutting mechanism to move to the position where cutting is required, the output shaft of the electric push cylinder moves downward to push the fixing plate and the vibrating knife downward, so that the cutting head of the vibrating knife contacts the heat insulation cotton. Then, the positioning mechanism drives the vibrating knife to move along a certain trajectory according to the preset cutting shape to complete the cutting of the heat insulation cotton. When the heat insulation cotton is cut, debris will be generated, and these debris will float into the air near the cutting head of the vibrating knife. At this time, the vacuum pump extracts the air near the cutting head through the hose and the dust collection elbow, and sucks the debris in the air into the connecting component through the dust collection elbow and the hose for collection, which can reduce the heat insulation cotton debris floating into the air during the cutting of the heat insulation cotton and reduce the pollution of the air around the device.

[0025] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application clearer, the following further details this application in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit this application.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which this application belongs; the terms used herein are only for the purpose of describing specific embodiments and do not limit this application. The terms "including" and "having" and any variations thereof in the specification and claims of this application and the above drawings are intended to cover non-exclusive inclusion.

[0027] Generally speaking, cotton products that can achieve heat insulation effects are collectively referred to as heat insulation cotton. Heat insulation cotton has the characteristics of high temperature resistance, non-flammability, low thermal conductivity, etc. Currently, heat insulation cotton widely used in industry is processed and produced with glass fiber as the material, such as fiberglass cotton and glass wool. Such products can be further processed by laminating aluminum foil and fiberglass cloth to make their uses more extensive. When producing heat insulation cotton, it is necessary to perform special-shaped cutting operations on heat insulation cotton of a certain specification so that the heat insulation cotton can adapt to different-shaped pasting parts.

[0028] In the heat insulation cotton cutting device in the related art, since heat insulation cotton is often made of loose foam cotton, when cutting heat insulation cotton, fine heat insulation cotton debris will be generated at the cut, and these debris will float into the air around the device, causing pollution to the environment. Workers inhaling these debris will also cause damage to the human body.

[0029] Based on this, in order to improve the problem that the debris generated during the cutting of heat insulation cotton in the related art will pollute the air, the embodiments of the present application provide the following solutions.

[0030] Please refer to Figures 1 to 4 together. The embodiments of the present application provide a heat insulation cotton cutting device, including a frame 1, a positioning mechanism, a cutting mechanism, and a dust collection mechanism.

[0031] Please refer to Figures 1 to 5, a positioning mechanism is arranged on the frame body 1 for moving the cutting mechanism. The cutting mechanism includes an electric push cylinder 31, a fixing plate 32, a fixing ring 33 and a vibrating knife 34. The positioning mechanism includes a first slide rail 21, a sliding support plate 22, a second slide rail 23 and a positioning assembly 24. The first slide rail 21 is arranged on the frame body 1, the sliding support plate 22 is slidably connected to the first slide rail 21, both ends of the second slide rail 23 are fixedly connected to the sliding support plate 22, the positioning assembly 24 is slidably connected to the second slide rail 23, the electric push cylinder 31 is arranged on the positioning assembly 24, the support plate 41 is fixedly connected to the sliding support plate 22, the fixing plate 32 is arranged on the output shaft of the electric push cylinder 31, the fixing ring 33 is arranged on the fixing plate 32, and the vibrating knife 34 is fixedly connected inside the fixing ring 33. The dust collection mechanism includes a support plate 41, a vacuum pump 42, a connecting component, a hose 44 and a dust collection elbow 45. The dust collection elbow 45 passes through the fixing plate 32, the vacuum pump 42 is arranged on the support plate 41, one end of the dust collection elbow 45 is provided with a dust collection port 451, the other end of the dust collection elbow 45 is provided with a fixing protrusion 452. The connecting component includes a connecting ring 431, a first connecting head 432, a second connecting head 433, a filter element 434 and a connecting pipe 435. The first connecting head 432 is communicated with the air inlet end of the vacuum pump 42. The connecting ring 431 is sleeved on the first connecting head 432 and is rotatably connected to the first connecting head 432. Threads are provided on the inner circumferential surface of the connecting ring 431 and the outer circumferential surface of the second connecting head 433. The second connecting head 433 is threadedly connected to the connecting ring 431. The filter element 434 is arranged inside the connecting ring 431. The outer circumferential surface of the filter element 434 abuts against the inner circumferential surface of the connecting ring 431. The bottom end of the filter element 434 abuts against the first connecting head 432. The top end of the filter element 434 abuts against the second connecting head 433. A first through hole 4331 is provided on the second connecting head 433. The connecting pipe 435 is arranged at the top end of the second connecting head 433 and is communicated with the inside of the second connecting head 433 through the first through hole 4331. One end of the hose 44 is communicated with the connecting pipe 435, and the inner circumferential surface of the other end of the hose 44 is in interference fit with the fixing protrusion 452.

[0032] As can be seen from the above, for a heat insulation cotton cutting device provided by an embodiment of the present application, when the device works, the sliding support plate 22 slides on the first slide rail 21 to drive the support plate 41 and the second slide rail 23 to move. The positioning assembly 24 slides on the second slide rail 23 to drive the electric push cylinder 31 to move. The output shaft of the electric push cylinder 31 then drives the fixed plate 32 and the cutting mechanism to move. Thus, after moving the cutting mechanism to the position to be cut according to the preset settings, the output shaft of the electric push cylinder 31 moves downward to push the fixed plate 32, the dust collection elbow 45, and the vibrating knife 34 downward, so that the cutting head of the vibrating knife 34 contacts the heat insulation cotton. Then, the positioning mechanism drives the vibrating knife 34 to move along a certain trajectory according to the preset cutting shape to complete the cutting of the heat insulation cotton. When the heat insulation cotton is cut, debris will be generated, and these debris will float into the air near the cutting head of the vibrating knife 34. At this time, the vacuum pump 42 extracts the air near the cutting head through the hose 44 and the dust collection elbow 45, and sucks the debris in the air into the inside of the second connector 433 through the dust collection elbow 45 and the hose 44. The debris in the air passing through the filter element 434 will be filtered out by the filter element 434. The filtered air is discharged into the air through the second connector 433, the intake end of the vacuum pump 42, and the exhaust end of the vacuum pump 42 under the suction of the vacuum pump 42, which can reduce the heat insulation cotton debris floating into the air during the cutting of the heat insulation cotton and reduce the pollution of the air around the device; the fixing protrusion 452 can make the hose 44 and the dust collection elbow 45 be connected more tightly, preventing the connection between the hose 44 and the dust collection elbow 45 from being detached due to the continuous twisting of the hose 44 during the operation of the device; after the device works for a long time, the debris adsorbed inside the filter element 434 will gradually increase. When there is too much debris, it will affect the filtering performance of the filter element 434. At this time, the staff can turn the connecting ring 431 to disconnect the connecting ring 431 from the second connector 433, then remove the second connector 433 to take out the filter element 434 and clean it. After cleaning, put the filter element 434 back to its original position and turn the connecting ring 431 again to connect the connecting ring 431 with the second connector 433. The first connector 432 and the second connector 433 will respectively abut against the bottom end and the top end of the filter element 434 to form a seal, thereby completing the cleaning work of the filter element 434 and ensuring the long-term operation of the device.

[0033] In some embodiments, please refer to Figures 5 to 7The first connector 432 is provided with a locking mechanism, which includes a housing 51, a slider 52, a rotating shaft 53 and a limit plate 54. The housing 51 is provided with a second through hole 511 and a threaded hole 512. One end of the hose 44 passes through the second through hole 511 and abuts against the housing 51. The connecting pipe 435 passes through the housing 51 and has an interference fit with the inner circumference of the hose 44. A slide groove 513 is also provided inside the housing 51. The slider 52 is slidably connected inside the slide groove 513. A plurality of anti-slip strips are provided on the slider 52. 522, the anti-slip strip 522 abuts against the outer peripheral surface of the hose 44, and a silicone pad 523 is also provided on the slider 52, and the silicone pad 523 abuts against the inner surface of the slider 52. A limiting groove 521 is provided inside the slider 52, and the limiting plate 54 is rotatably connected inside the limiting groove 521. A thread is provided on the rotating shaft 53, and the rotating shaft 53 is threadedly connected to the shell 51 through a threaded hole 512. One end of the rotating shaft 53 passes through the threaded hole 512 and is fixedly connected to the limiting plate 54, and the other end of the rotating shaft 53 is provided with a handle 531.

[0034] With such arrangement, when the device is working, since the dust collecting curved pipe 45 moves continuously relative to the connecting pipe 435, the hose 44 will twist continuously, which may cause the connection between the hose 44 and the connecting pipe 435 to fall off. When installing the hose 44, the staff can insert one end of the hose 44 into the shell 51 through the second through hole 511, and insert the connecting pipe 435 into the hose 44, and then turn the shaft 53 through the handle 531, and the shaft 53 drives the limiting plate 54 to rotate inside the limiting groove 521, and the shell 51 drives the shaft 53 to move into the shell 51 through the threaded hole 512. The rotating shaft 53 then pushes the slider 52 to slide inside the slide groove 513 through the limit plate 54 until the anti-slip strip 522 presses the hose 44 against the connecting pipe 435. The anti-slip strip 522 can increase the friction between the slider 52 and the hose 44, making the connection between the hose 44 and the slider 52 tighter. At this time, the silicone pad 523 will contact the inner surface of the shell 51 and be compressed. The silicone pad 523 will apply a reverse thrust to the slider 52 to provide feedback to the staff to prevent the staff from over-twisting the rotating shaft 53, causing the thread to be bitten or damaged. At this point, the installation and locking of the hose 44 is completed.

[0035] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
