Description

Technical Field

[0001] The present invention relates to the technical field of sheet cutting, and particularly relates to a sheet cutting device for disinfectant cabinet production. Background Art

[0002] When disinfectant cabinets are produced, metal sheets of different specifications need to be assembled. During this period, the raw metal sheets need to be cut according to specific specifications by a guillotine shear. The guillotine shear is a machine that uses a moving upper blade and a fixed lower blade, with a reasonable blade gap, to apply a shearing force to metal sheets of various thicknesses, causing the sheets to break and separate according to the required dimensions. It is classified into a straight-blade guillotine shear and a circular-blade guillotine shear according to the shape of the scissors.

[0003] For example, in a Chinese patent application document with the publication number CN114309759A and the name of a numerically controlled hydraulic guillotine shear, during the working process, first, the large sheet to be processed is placed on the workbench, then the sheet is pushed to move it to the specified position, and then the device is started. At this time, the second hydraulic rod extends, and the bottom end of the second hydraulic rod presses the large sheet downward to make it fit with the workbench. During this process, the first hydraulic rod contracts, and when the first hydraulic rod is completely contracted, it starts to extend. During the extension process, it drives the guillotine blade to move downward and cut the sheet.

[0004] In view of the above related technologies, since the sheet is relatively thin, and during production, transportation, or storage, the metal sheet may bulge due to uneven heating. When the second hydraulic rod moves downward to press the metal sheet, since the bulging part of the metal sheet is difficult to determine, when the second hydraulic rod moves downward and cannot contact the bulging part, the metal sheet still remains bulged. At this time, the cutting edge will be uneven, reducing the cutting accuracy. When the second hydraulic rod moves downward and contacts the bulging part, and the bulging part is located on both sides of the metal sheet, there is a probability that the metal sheet with bulges on both sides will be squeezed inward, which is not conducive to the flattening and cutting of the metal sheet, reducing the cutting accuracy, and even may cause the sheet to be scrapped. Summary of the Invention

[0005] In view of this, the present invention provides a sheet cutting device for disinfectant cabinet production, aiming to solve the problems that the bulged metal sheet cannot be flattened when being pressed, and the metal sheet with bulges on both sides is squeezed inward.

[0006] To solve the above technical problems, the present invention provides a sheet cutting device for the production of disinfection cabinets, including a bracket, a lower blade and an upper blade for cutting the sheet, and a first linear driver for driving the movement of the upper blade; the bracket is provided with a first belt conveyor for transporting the sheet to the upper blade, one end of the bracket close to the upper blade is fixedly connected with a second linear driver, the driving shaft of the second linear driver is fixedly connected with a leaf spring assembly, the leaf spring assembly is composed of an upper leaf spring and a lower leaf spring which are hinged to each other, both the upper leaf spring and the lower leaf spring arch outwards from the leaf spring assembly, and when the lower leaf spring moves downwards, it can flatten the sheet from the middle to both ends while pressing the sheet tightly.

[0007] By adopting the above technical solution, the lower leaf spring gradually becomes flat from the middle to both ends to press the sheet tightly, and at the same time, the lower leaf spring flattens the sheet from the middle to both ends, reducing the probability that there are still protrusions or wrinkles when the sheet is pressed tightly, improving the flatness when the sheet is fixed, and thus improving the cutting accuracy of the sheet.

[0008] Optionally, the leaf spring assembly is fixedly connected with a guide rod, and the guide rod is horizontally slidably connected with the bracket.

[0009] Optionally, an airbag is fixedly connected between the upper leaf spring and the lower leaf spring, both the upper leaf spring and the lower leaf spring are provided with air inlet holes communicating with the inside of the airbag, and a one-way valve is connected in series inside the air inlet holes.

[0010] By adopting the above technical solution, the airbag outputs air flow downward through the air inlet hole opened on the lower leaf spring under the extrusion of the upper leaf spring and the lower leaf spring, and the air flow flowing through the surface of the sheet can clean the chips on the surface of the sheet, reducing the probability of the phenomenon of tool breakage when the upper blade and the lower blade cut the sheet.

[0011] Optionally, the bracket is provided with a limiting plate at one end of the upper blade away from the first belt conveyor, and when the sheet abuts against the limiting plate, the upper blade cuts the sheet.

[0012] By adopting the above technical solution, when the sheet abuts against the limiting plate driven by the first belt conveyor, the upper blade cuts the sheet, improving the cutting accuracy of the sheet.

[0013] Optionally, a fixing block is fixedly connected to the outer side surface of the bracket, the limiting plate is fixedly connected with an adjusting rod slidably connected with the fixing block, and the fixing block is threadedly connected with a fastening screw, and the fastening screw can be rotated to press the adjusting rod tightly.

[0014] Optionally, the first belt conveyor includes a connecting frame arranged on the bracket, the connecting frame is fixedly connected with a rotating source, the connecting frame is rotatably connected with a driving roller and a supporting roller, the driving shaft of the rotating source is fixedly connected with the driving roller, and a first conveyor belt is sleeved on the outer side surfaces of the driving roller and the supporting roller.

[0015] Optionally, a third linear actuator is fixedly connected to the upper surface of the connecting frame. A support member is fixedly connected to the drive shaft of the third linear actuator. A second belt conveyor is rotatably connected to the support member. The sheet is located between the first belt conveyor and the second belt conveyor.

[0016] Optionally, a support rod is vertically and fixedly connected to the support member. The second belt conveyor is slidably connected to the support rod. An adjusting spring is connected between the second belt conveyor and the support member.

[0017] By adopting the above technical solution, the adjusting spring presses the second conveyor belt downward through the connecting member, improving the stability of clamping and conveying the sheet by the first conveyor belt and the second conveyor belt.

[0018] Optionally, the connecting frame is fixedly connected with a first support plate for supporting the first conveyor belt. There are two first belt conveyors and the second belt conveyor, which are arranged perpendicular to the moving direction of the sheet and are arranged at both ends of the bracket. The connecting frame is hinged to the bracket. The connecting frame is provided with a chute. A fourth linear actuator is fixedly connected to the lower end of the bracket. A transmission rod is fixedly connected to the drive shaft of the fourth linear actuator. The end of the transmission rod away from the fourth linear actuator is slidably arranged in the chute.

[0019] By adopting the above technical solution, the sheet suspended between the limiting plate and the bracket is bent into a V shape, reducing the angle of downward bending of the sheet due to its own gravity. Thereby, the accuracy of the length of the sheet between the limiting plate and the upper blade is increased, which is beneficial to improving the accuracy of the cut sheet product.

[0020] Optionally, a support wheel that can abut against the sheet is rotatably connected to the bracket. The support wheel is located in the middle of the two first belt conveyors.

[0021] In summary, compared with the prior art, the present invention includes at least one of the following beneficial technical effects:

[0022] 1. The downward movement of the lower leaf spring causes the middle part of the lower leaf spring to abut against the sheet. At the same time, the lower leaf spring continues to move downward and deform. The lower leaf spring gradually becomes flat from the middle to both ends to press the sheet tightly. At the same time, the lower leaf spring flattens the sheet from the middle to both ends, reducing the probability that the sheet still has protrusions or wrinkles when being pressed tightly, improving the flatness of the sheet when being fixed, and thereby improving the cutting accuracy of the sheet.

[0023] 2. The airbag outputs air downward through the air holes provided in the lower leaf spring under the extrusion of the upper leaf spring and the lower leaf spring. The air flow flowing through the surface of the sheet can clean the chips on the surface of the sheet, reducing the probability of the upper blade and the lower blade chipping when cutting the sheet.

[0024] 3. The sheet between the limit plate and the bracket is bent into a V shape, reducing the angle of downward bending of the sheet due to its own gravity. This increases the accuracy of the length of the sheet between the limit plate and the upper blade, which is beneficial to improving the accuracy of the finished sheet cut.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be described clearly and completely below. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present invention. Figures 1-5 This embodiment provides a sheet cutting device for the production of disinfection cabinets. Refer to

[0032] Figure 1 ​, Figure 2 and Figure 3 , a sheet cutting device for disinfecting cabinet production includes a bracket 1, a first belt conveyor 3 for conveying sheets, a cutting mechanism 2 for cutting sheets, and a fixing mechanism 4 for pressing the sheets.

[0033] Referring to Figure 1 , Figure 2 and Figure 3 , the bracket 1 stands upright on the horizontal plane, and the first belt conveyor 3 is connected to the upper surface of the bracket 1. The cutting mechanism 2 is arranged at one end of the bracket 1. The cutting mechanism 2 includes a first linear driver 23, an upper blade 22 and a lower blade 21. The first linear driver 23 and the lower blade 21 are fixedly connected to the bracket 1 from top to bottom. The upper blade 22 is fixedly connected to the driving shaft of the first linear driver 23. The first belt conveyor 3 transports the sheet between the upper blade 22 and the lower blade 21. The first linear driver 23 drives the upper blade 22 to move downward, so that the upper blade 22 cooperates with the lower blade 21 to cut the sheet.

[0034] Referring to Figure 1 , Figure 2 and Figure 3 , the fixing mechanism 4 includes a second linear driver 41 and a leaf spring assembly 42. The second linear driver 41 is fixedly connected to the bracket 1 near the upper blade 22. The leaf spring assembly 42 is fixedly connected to the driving shaft of the second linear driver 41. The leaf spring assembly 42 consists of an upper leaf spring 421 and a lower leaf spring 422. The two ends of the upper leaf spring 421 and the lower leaf spring 422 are hinged to each other. The middle parts of the upper leaf spring 421 and the lower leaf spring 422 arch outwards from the leaf spring assembly 42. The upper leaf spring 421 is fixedly connected to the driving shaft of the second linear driver 41.

[0035] The first belt conveyor 3 transports the sheet between the upper blade 22 and the lower blade 21. The second linear driver 41 drives the leaf spring assembly 42 to move downward. The downward movement of the lower leaf spring 422 causes the middle part of the lower leaf spring 422 to abut against the sheet. At the same time, the lower leaf spring 422 continues to move downward and deform. The lower leaf spring 422 gradually changes from the middle to both ends into a flat shape to press the sheet. At the same time, the lower leaf spring 422 flattens the sheet from the middle to both ends, reducing the probability that the sheet still has protrusions or wrinkles when being pressed, and improving the flatness of the sheet when being fixed. Finally, the first linear driver 23 drives the upper blade 22 to move downward to cut the sheet. The cut sheet falls, and the sheet on the bracket 1 is continuously transported to continuously cut the sheet.

[0036] Referring to Figure 1 and Figure 3 , guide rods 43 are fixedly connected to both ends of the leaf spring assembly 42. The guide rods 43 move in the horizontal direction as the leaf spring assembly 42 deforms, improving the stability of the deformation of the leaf spring assembly 42.

[0037] Reference Figure 1 and Figure 3 As shown, an airbag 5 is fixedly connected between the upper leaf spring 421 and the lower leaf spring 422. The upper leaf spring 421 and the lower leaf spring 422 are both provided with air injection holes 44 communicating with the inside of the airbag 5. A one-way valve 45 is connected in series inside the air injection hole 44. The one-way valve 45 inside the upper leaf spring 421 restricts the air from being output from the airbag 5, and the one-way valve 45 inside the lower leaf spring 422 restricts the external air from entering the airbag 5. When the lower leaf spring 422 is pressed to deform the plate material, the lower leaf spring 422 drives the upper leaf spring 421 to deform synchronously, reducing the space between the upper leaf spring 421 and the lower leaf spring 422. The airbag 5 outputs air flow downward through the air injection hole 44 provided in the lower leaf spring 422 under the extrusion of the upper leaf spring 421 and the lower leaf spring 422. The air flow flowing through the surface of the plate material can clean the chips on the surface of the plate material, reducing the probability of the upper blade 22 and the lower blade 21 chipping when cutting the plate material. When the leaf spring assembly 42 resets, it drives the airbag 5 to expand, and the external air enters the airbag 5 through the air injection hole 44 provided in the upper leaf spring 421. In addition, the airbag 5 can support the leaf spring assembly 42. When the airbag 5 outputs gas through the air injection hole 44 of the lower leaf spring 422, it can buffer the deformation of the leaf spring assembly 42, increasing the stability of the deformation of the leaf spring assembly 42.

[0038] Reference Figure 2 and Figure 3 As shown, fixed blocks 12 are fixedly connected to both sides of the bracket 1. The fixed blocks 12 are slidably connected with adjusting rods 13, and the fixed blocks 12 are threadedly connected with fastening screws 14. Rotating the fastening screws 14 can press the adjusting rods 13. A limiting plate 11 is fixedly connected between the adjusting rods 13 on both sides of the bracket 1. The limiting plate 11 is located at one end of the upper blade 22 away from the first belt conveyor 3. The operator slides the adjusting rod 13 to adjust the distance between the limiting plate 11 and the upper blade 22, and then tightens the fastening screw 14. When the plate material abuts against the limiting plate 11 driven by the first belt conveyor 3, the upper blade 22 cuts the plate material, improving the cutting accuracy of the plate material.

[0039] Reference Figure 1 and Figure 4 As shown, the first belt conveyor 3 includes a connecting frame 31, a rotating source 32, a driving roller 33, a supporting roller 34 and a first conveyor belt 35. The connecting frame 31 is arranged on the bracket 1. The rotating source 32 is fixedly connected to the outer side surface of the connecting frame 31. Both the driving roller 33 and the supporting roller 34 are rotatably connected to the connecting frame 31. The driving shaft of the rotating source 32 is fixedly connected to the driving roller 33. The first conveyor belt 35 is sleeved on the outer side surfaces of the driving roller 33 and the supporting roller 34. The rotating source 32 drives the first conveyor belt 35 to run and convey the plate material through the driving roller 33. The connecting frame 31 is fixedly connected with a first support plate 36. The first support plate 36 is located inside the first conveyor belt 35 and is used to support the conveyor belt, improving the stability of the first conveyor belt 35 in transporting the plate material.

[0040] Reference Figure 1 and Figure 4 On the upper surface of the connecting frame 31, a third linear driver 6 is fixedly connected. The drive shaft of the third linear driver 6 is fixedly connected with a support member 61. The support member 61 is rotatably connected with a second belt conveyor 7. The sheet is located between the first belt conveyor 3 and the second belt conveyor 7. The movement of the sheet drives the second belt conveyor 7 to operate through frictional force. The second belt conveyor 7 cooperates with the first belt conveyor 3 to clamp the sheet, improving the stability of sheet conveying. In addition, according to the width of the sheet, the third linear driver 6 drives the second belt conveyor 7 to move through the support member 61, adjusting the distance between the second belt conveyor 7 and the sheet.

[0041] Reference Figure 1 and Figure 4 The second belt conveyor 7 includes a connecting member 71, a driving roller 72, a driven roller 73 and a second conveyor belt 74. The support member 61 is vertically and fixedly connected with a support rod 63. The connecting member 71 is vertically slidably connected with the support member 61 through the support rod 63. Both the driving roller 72 and the driven roller 73 are rotatably connected with the connecting member 71. The second conveyor belt 74 is sleeved on the outer sides of the driving roller 72 and the driven roller 73. The sheet drives the second conveyor belt 74 to operate through frictional force. The inner side surface of the connecting member 71 is fixedly connected with a second support plate 75. The support member 61 abuts against the inner bottom surface of the second conveyor belt 74, thereby supporting the second conveyor belt 74.

[0042] Reference Figure 4 Between the second belt conveyor 7 and the support member 61, an adjusting spring 64 is connected. The adjusting spring 64 is sleeved on the outer side of the support rod 63. According to the thickness of the sheet, the adjusting spring 64 presses the connecting member 71 downward, and the connecting member 71 presses the second conveyor belt 74 downward, improving the stability of clamping and conveying the sheet by the first conveyor belt 35 and the second conveyor belt 74.

[0043] Reference Figure 1 and Figure 5 There are two first belt conveyors 3 and second belt conveyors 7, which are arranged perpendicular to the moving direction of the sheet at both ends of the bracket 1. The connecting frame 31 is hinged to the bracket 1. The connecting frame 31 is provided with a chute 311. The lower end of the bracket 1 is fixedly connected with a fourth linear driver 8. The drive shaft of the fourth linear driver 8 is fixedly connected with a transmission rod 81. The end of the transmission rod 81 away from the fourth linear driver 8 is slidably arranged in the chute 311.

[0044] The drive shaft of the fourth linear driver 8 drives the transmission rod 81 to move upward. The transmission rod 81 drives the two connecting frames 31 to rotate upward into a V shape through the chute 311. While conveying the board, the first belt conveyor 3 and the second belt conveyor 7 rotate synchronously with the connecting frame 31 to bend the board into a V shape, generating elastic deformation, thereby increasing the stiffness of the board. Among them, the first support plate 36 supports the first conveyor belt 35, and the second support plate 75 supports the second conveyor belt 74 to bend the board. Thus, when the board abuts against the limiting plate 11, the board suspended between the limiting plate 11 and the bracket 1 is bent into a V shape, reducing the angle of downward bending of the board due to its own gravity. Thereby, the accuracy of the length of the board between the limiting plate 11 and the upper blade 22 is increased, which is beneficial to improving the accuracy of the finished board cut off.

[0045] Referring to Figure 1 and Figure 5 , the bracket 1 is rotatably connected with a support wheel 15 that can abut against the board. The support wheel 15 is located in the middle of the two first belt conveyors 3 to support the board, reducing the friction generated between the moving board and the bracket 1.

[0046] The implementation principle of the board cutting device for disinfection cabinet production in the embodiment of the present invention is as follows: The drive shaft of the fourth linear driver 8 drives the transmission rod 81 to move upward. The transmission rod 81 drives the two connecting frames 31 to rotate upward into a V shape. While conveying the board, the first belt conveyor 3 and the second belt conveyor 7 rotate synchronously with the connecting frame 31 to bend the board to generate elastic deformation until the board abuts against the limiting plate 11. The drive shaft of the fourth linear driver 8 drives the first belt conveyor 3 and the second belt conveyor 7 to reset and be parallel to the bracket 1.

[0047] The second linear driver 41 drives the leaf spring assembly 42 to move downward. The downward movement of the lower leaf spring 422 causes the middle part of the lower leaf spring 422 to abut against the board. The lower leaf spring 422 gradually changes from the middle to both ends into a flat shape to press the board. At the same time, the lower leaf spring 422 flattens the board from the middle to both ends. When the lower leaf spring 422 presses the board and deforms, the airbag 5 outputs air downward through the air holes 44 opened on the lower leaf spring 422 under the extrusion of the upper leaf spring 421 and the lower leaf spring 422. The air flow flowing through the surface of the board can clean the chips on the surface of the board. Finally, the first linear driver 23 drives the upper blade 22 to move downward to cut the board. The cut-off board falls, and the first belt conveyor 3 continues to transport the board to continuously cut the board.

[0048] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and defined, the terms "installed", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0049] The above are the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
