Description

Technical Field

[0001] The invention relates to the technical field of plate cutting, and in particular to a plate cutting device for producing a disinfection cabinet. Background Art

[0002] Disinfection cabinets need to assemble metal plates of different specifications during production, and the metal plate raw materials need to be cut according to specific specifications using shearing machines. Shearing machines use a moving upper blade and a fixed lower blade, and a reasonable blade gap to apply shearing force to metal plates of various thicknesses, so that the plates are broken and separated according to the required size. They are classified into straight knife shearing machines and disc knife shearing machines according to the shape of the scissors.

[0003] For example, in the Chinese patent application document with publication number CN114309759A, which is named as a CNC hydraulic shearing machine, during the working process, the large plate to be processed is first placed on the workbench, and then the plate is pushed to move the plate 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 plate downward to make it fit together with the workbench. During this process, the first hydraulic rod contracts, and when the first hydraulic rod is fully contracted, it begins to extend, and during the extension process, it drives the shearing knife to move downward and cut the plate.

[0004] Regarding the above-mentioned related technologies, since the sheet is relatively thin, and during the production, transportation or storage process, the metal sheet is heated unevenly and bulges may occur. When the second hydraulic rod moves downward to press the metal sheet, since the bulge of the metal sheet is difficult to determine, when the second hydraulic rod moves downward and cannot contact the bulge, the metal sheet still remains in a bulge state, which will cause uneven cutting edges and reduce cutting accuracy. When the second hydraulic rod moves downward and contacts the bulge, and the bulge is located on both sides of the metal sheet, there is a probability that the bulges on both sides of the metal sheet will be squeezed inward, which is not conducive to the flat cutting of the metal sheet, reduces the cutting accuracy, and may even cause the sheet to be scrapped. Summary of the invention

[0005] In view of this, the present invention provides a plate cutting device for the production of a disinfection cabinet, which aims to solve the problem that the raised metal plate cannot be flattened when the metal plate is pressed, and the raised metal plates on both sides are squeezed inward.

[0006] In order to solve the above technical problems, the present invention provides a plate cutting device for the production of disinfection cabinets, comprising a bracket, a lower blade and an upper blade for cutting the plate, and a first linear drive for driving the upper blade to move; the bracket is provided with a first belt conveyor for transporting the plate to the upper blade, and the bracket is fixedly connected to a second linear drive at one end close to the upper blade, and the driving shaft of the second linear drive is fixedly connected to a leaf spring assembly, and the leaf spring assembly is composed of an upper leaf spring and a lower leaf spring hinged to each other, and the upper leaf spring and the lower leaf spring are both arched toward the outside of the leaf spring assembly, and the lower leaf spring moves downward to press the plate and flatten the plate from the middle to both ends.

[0007] By adopting the above technical solution, the lower leaf spring gradually changes into a flat surface from the middle to both ends to compress the plate. At the same time, the lower leaf spring flattens the plate from the middle to both ends, thereby reducing the probability of bulges or wrinkles on the plate when it is compressed, and improving the flatness of the plate when it is fixed, thereby improving the cutting accuracy of the plate.

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

[0010] By adopting the above technical solution, the airbag outputs air downward through the air holes opened in the lower leaf spring under the squeezing of the upper leaf spring and the lower leaf spring. The airflow flowing through the surface of the plate can clean the chips on the surface of the plate, reducing the probability of chipping when the upper blade and the lower blade cut the plate.

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

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

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

[0016] Optionally, the support member is vertically fixedly connected to a support rod, the second belt conveyor is slidably connected to the support rod, and an adjustment 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 piece, thereby improving the stability of the first conveyor belt and the second conveyor belt in clamping and conveying the plate.

[0020] Optionally, the bracket is rotatably connected to a support wheel capable of abutting against the plate, and the support wheel is located between 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: 1.

DETAILED DESCRIPTION

[0026] To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the following will be combined with the embodiments of the present invention. Figure 1-Figure 5 , the technical scheme of the embodiment of the present invention is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0027] This embodiment provides a plate cutting device for producing a disinfection cabinet, referring to Figure 1 , Figure 2 and Figure 3A plate cutting device for producing a disinfection cabinet comprises a bracket 1, a first belt conveyor 3 for conveying the plate, a cutting mechanism 2 for cutting the plate and a fixing mechanism 4 for pressing the plate.

[0028] Reference Figure 1 , Figure 2 and Figure 3 The bracket 1 is erected on a 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, and 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, and the upper blade 22 is fixedly connected to the driving shaft of the first linear driver 23. The first belt conveyor 3 transports the plate to between the upper blade 22 and the lower blade 21, and 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 plate.

[0029] Reference Figure 1 , Figure 2 and Figure 3 The fixing mechanism 4 includes a second linear actuator 41 and a leaf spring assembly 42. The second linear actuator 41 is fixedly connected to the bracket 1 near the upper blade 22, and the leaf spring assembly 42 is fixedly connected to the driving shaft of the second linear actuator 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, and the middle parts of the upper leaf spring 421 and the lower leaf spring 422 are arched toward the outside of the leaf spring assembly 42. The upper leaf spring 421 is fixedly connected to the driving shaft of the second linear actuator 41.

[0030] The first belt conveyor 3 conveys the plate to between the upper blade 22 and the lower blade 21, and the second linear actuator 41 drives the leaf spring assembly 42 to move downward, and the lower leaf spring 422 moves downward so that the middle part of the lower leaf spring 422 abuts against the plate. At the same time, the lower leaf spring 422 continues to move downward and deform, and the lower leaf spring 422 gradually changes from the middle to both ends to a flat surface to press the plate. At the same time, the lower leaf spring 422 flattens the plate from the middle to both ends, reducing the probability of bulges or wrinkles when the plate is pressed, and improving the flatness of the plate when it is fixed. Finally, the first linear actuator 23 drives the upper blade 22 to move downward to cut the plate, and the cut plate falls, and the plate on the bracket 1 is transported continuously to cut the plate continuously.

[0031] Reference Figure 1 and Figure 3 Both ends of the leaf spring assembly 42 are fixedly connected with guide rods 43 , and the guide rods 43 move in the horizontal direction as the leaf spring assembly 42 deforms, thereby improving the deformation stability of the leaf spring assembly 42 .

[0032] Reference Figure 1 and Figure 3The airbag 5 is fixedly connected between the upper leaf spring 421 and the lower leaf spring 422. Both the upper leaf spring 421 and the lower leaf spring 422 are provided with an air delivery hole 44 connected to the inside of the airbag 5. A one-way valve 45 is connected in series inside the air delivery hole 44. The one-way valve 45 in the upper leaf spring 421 limits the output of air from the airbag 5, and the one-way valve 45 in the lower leaf spring 422 limits the external air from entering the airbag 5. When the lower leaf spring 422 compresses the plate to deform, the lower leaf spring 422 drives the upper leaf spring 421 to deform synchronously, so that the space between the upper leaf spring 421 and the lower leaf spring 422 becomes smaller. Under the pressure of the upper leaf spring 421 and the lower leaf spring 422, the airbag 5 outputs airflow downward through the air delivery hole 44 provided in the lower leaf spring 422. The airflow flowing through the surface of the plate can clean the chips on the surface of the plate, reducing the probability of the upper blade 22 and the lower blade 21 breaking the plate when cutting the plate. When the leaf spring assembly 42 is reset, it drives the airbag 5 to expand, and external air enters the airbag 5 through the air delivery hole 44 provided in the upper leaf spring 421. In addition, the airbag 5 can support the leaf spring assembly 42, and when the airbag 5 outputs gas through the air delivery hole 44 of the lower leaf spring 422, it can buffer the deformation of the leaf spring assembly 42, thereby increasing the stability of the deformation of the leaf spring assembly 42.

[0033] Reference Figure 2 and Figure 3 The two sides of the bracket 1 are fixedly connected with a fixing block 12, and the fixing block 12 is slidably connected with an adjusting rod 13. The fixing block 12 is threadedly connected with a fastening screw 14, and the fastening screw 14 can be rotated to press the adjusting rod 13. The 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 the 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 is driven by the first belt conveyor 3 and abuts against the limiting plate 11, the upper blade 22 cuts the plate, thereby improving the cutting accuracy of the plate.

[0034] Reference Figure 1 and Figure 4 The first belt conveyor 3 includes a connecting frame 31, a rotation 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 of the connecting frame 31, the driving roller 33 and the supporting roller 34 are both 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 of the driving roller 33 and the supporting roller 34, and the rotating source 32 drives the first conveyor belt 35 to run and convey the plate through the driving roller 33. The connecting frame 31 is fixedly connected with a first supporting plate 36, which is located on the inner side of the first conveyor belt 35 and is used to support the conveyor belt and improve the stability of the first conveyor belt 35 in transporting the plate.

[0035] Reference Figure 1 and Figure 4The upper surface of the connecting frame 31 is fixedly connected with a third linear actuator 6, the driving shaft of the third linear actuator 6 is fixedly connected with a support 61, the support 61 is rotatably connected with a second belt conveyor 7, the plate is located between the first belt conveyor 3 and the second belt conveyor 7, the movement of the plate drives the second belt conveyor 7 to run through friction, the second belt conveyor 7 cooperates with the first belt conveyor 3 to clamp the plate, and improves the stability of plate transportation. In addition, according to the width of the plate, the third linear actuator 6 drives the second belt conveyor 7 to move through the support 61, and adjusts the distance between the second belt conveyor 7 and the plate.

[0036] 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 fixedly connected to the support rod 63, the connecting member 71 is vertically slidably connected to the support member 61 through the support rod 63, the driving roller 72 and the driven roller 73 are both rotatably connected to the connecting member 71, and the second conveyor belt 74 is sleeved on the outer side of the driving roller 72 and the driven roller 73, and the plate drives the second conveyor belt 74 to run through friction. The inner side of the connecting member 71 is fixedly connected to the second support plate 75, and the support member 61 abuts against the inner bottom surface of the second conveyor belt 74, thereby supporting the second conveyor belt 74.

[0037] Reference Figure 4 An adjusting spring 64 is connected between the second belt conveyor 7 and the support member 61. The adjusting spring 64 is sleeved on the outer side of the support rod 63. The adjusting spring 64 presses the connecting member 71 downward according to the thickness of the plate. The connecting member 71 presses the second conveyor belt 74 downward to improve the stability of the first conveyor belt 35 and the second conveyor belt 74 in clamping and conveying the plate.

[0038] Reference Figure 1 and Figure 5 The first belt conveyor 3 and the second belt conveyor 7 are provided with two and are arranged at both ends of the bracket 1 perpendicular to the moving direction of the plate. The connecting frame 31 is hinged to the bracket 1, and the connecting frame 31 is provided with a slide groove 311. The lower end of the bracket 1 is fixedly connected to the fourth linear drive 8, and the driving shaft of the fourth linear drive 8 is fixedly connected to the transmission rod 81. The end of the transmission rod 81 away from the fourth linear drive 8 is slidably set in the slide groove 311.

[0039] The driving shaft of the fourth linear actuator 8 drives the transmission rod 81 to move upward, and the transmission rod 81 drives the two connecting frames 31 to rotate upward into a V shape through the slide slot 311. The first belt conveyor 3 and the second belt conveyor 7 rotate synchronously with the connecting frame 31 while conveying the plate to bend the plate into a V shape to produce elastic deformation, thereby increasing the rigidity of the plate. 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 plate. Therefore, when the plate abuts against the limit plate 11, the plate suspended between the limit plate 11 and the bracket 1 is bent into a V shape, which reduces the angle of the plate bent downward by its own gravity, thereby increasing the accuracy of the length of the plate between the limit plate 11 and the upper blade 22, which is conducive to improving the accuracy of the finished plate product being cut.

[0040] Reference Figure 1 and Figure 5 The support 1 is rotatably connected to a support wheel 15 that can abut against the plate. The support wheel 15 is located between the two first belt conveyors 3 to support the plate and reduce the friction between the plate and the support 1.

[0041] The implementation principle of a plate cutting device for producing a disinfection cabinet according to an embodiment of the present invention is as follows: the driving shaft of the fourth linear actuator 8 drives the transmission rod 81 to move upward, and the transmission rod 81 drives the two connecting frames 31 to rotate upward in a V shape, and the first belt conveyor 3 and the second belt conveyor 7 rotate synchronously with the connecting frame 31 while conveying the plate to bend the plate to produce elastic deformation until the plate abuts against the limit plate 11. The driving shaft of the fourth linear actuator 8 drives the first belt conveyor 3 and the second belt conveyor 7 to reset to be parallel to the bracket 1.

[0042] The second linear actuator 41 drives the leaf spring assembly 42 to move downward, and the lower leaf spring 422 moves downward so that the middle part of the lower leaf spring 422 abuts against the sheet. The lower leaf spring 422 gradually changes from the middle to both ends to a plane to press the sheet, and at the same time, the lower leaf spring 422 flattens the sheet from the middle to both ends. When the lower leaf spring 422 presses the sheet and deforms, the airbag 5 outputs airflow downward through the air delivery hole 44 opened in the lower leaf spring 422 under the pressure of the upper leaf spring 421 and the lower leaf spring 422. The airflow flows through the surface of the sheet to clean the chips on the surface of the sheet. Finally, the first linear actuator 23 drives the upper blade 22 to move downward to cut the sheet, and the cut sheet falls, and the first belt conveyor 3 continues to transport the sheet to continuously cut the sheet.

[0043] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" 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 a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components.
