Description

Technical Field

[0001] The present invention belongs to the technical field of mixer manufacturing, and particularly relates to a cutting device for mixer manufacturing. Background Art

[0002] A mixer is a device used for mixing and reacting, and is usually used in fields such as chemical industry, pharmaceuticals, and food. The mixing tank is one of the important components of the mixer. During the processing of the mixing tank, it involves the cutting and blanking of metal sheets, the forming of metal sheets, and the welding process.

[0003] For the cutting and blanking of metal sheets, a shearing machine is generally used. A hydraulic shearing machine for processing narrow strip steel plates disclosed in the existing Chinese utility model patent (CN221516318 U) can cut metal plates through the opposite movement of the lower cutting tool head and the upper cutting tool head.

[0004] Although the above method can cut metal plates, since the lower cutting tool head is fixedly installed and the upper cutting tool head can only move up and down, therefore, the angle of the cutting surface of the metal plate is fixed relative to the device. When it is necessary to cut an isosceles trapezoidal metal plate, it can only be achieved by changing the feeding direction of the metal plate. Therefore, when blanking a metal plate similar to an isosceles trapezoid, it is necessary to frequently change the feeding direction of the metal plate, resulting in troublesome cutting of the metal plate. Summary of the Invention

[0005] The purpose of the embodiments of the present invention is to provide a cutting device for mixer manufacturing, aiming to solve the problem that when blanking a metal plate similar to an isosceles trapezoid, it is necessary to frequently change the feeding direction of the metal plate, resulting in troublesome cutting of the metal plate.

Detailed implementation manners

[0025] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the attached drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0026] The following describes in detail the specific implementation of the present invention with reference to specific embodiments.

[0027] As Figures 1-4 shown, a cutting device for manufacturing a mixer provided by an embodiment of the present invention includes a protective housing 101, and further includes: a rotating frame 102, a rotating sleeve 104 is fixed to the upper end of the rotating frame 102, and a rotating shaft 103 is fixed to the lower end of the rotating frame 102; a rotating cavity 111 provided in the protective housing 101, and the rotating frame 102 is rotatably connected to the rotating cavity 111 through the rotating sleeve 104 and the rotating shaft 103. Specifically, the rotating sleeve 104 is rotatably connected to the upper end of the rotating cavity 111, and the rotating shaft 103 is rotatably connected to the lower end of the rotating cavity 111; a fixed cutter 108 is fixed to the inner bottom of the rotating frame 102, two vertical guiding shafts 105 are fixed in the rotating frame 102, a lifting plate 106 is slidably connected to the two guiding shafts 105, a moving cutter 107 is fixed to the lower end of the lifting plate 106, and the moving cutter 107 cooperates with the fixed cutter 108; a first fixing frame 115 is fixed to the upper end of the protective housing 101, a telescopic cylinder 112 is fixed to the upper end of the first fixing frame 115, and the telescopic end of the telescopic cylinder 112 penetrates through the rotating sleeve 104 and is fixed to the upper end of the rotating frame 102; a rotating mechanism 4 is provided at the lower end of the protective housing 101, and the rotating mechanism 4 is used to drive the rotating shaft 103 to rotate; a stopping assembly 3 is provided on the rotating frame 102, and when the rotating frame 102 moves downward, the stopping assembly 3 restricts the rotation of the rotating frame 102.

[0028] In an embodiment of the present invention, the telescopic cylinder 112 can be a hydraulic cylinder, a pneumatic cylinder or an electric telescopic rod; in the initial state, the telescopic cylinder 112 is in a contracted state, the lifting plate 106 is located above the guide shaft 105, and the distance between the moving cutter 107 and the fixed cutter 108 is the largest. When in use, a metal plate is placed between the moving cutter 107 and the fixed cutter 108, the telescopic cylinder 112 extends, and under the guiding action of the guide shaft 105, the telescopic cylinder 112 drives the lifting plate 106 to move downward. The lifting plate 106 drives the moving cutter 107 to move downward, and the downward moving moving cutter 107 cooperates with the fixed cutter 108 to cut the plate. When the rotating frame 102 moves downward, the stopping assembly 3 restricts the rotation of the rotating frame 102, thereby preventing the rotating frame 102 from driving the moving cutter 107 and the fixed cutter 108 to rotate, and preventing the moving cutter 107 and the fixed cutter 108 from horizontally moving when cutting the metal plate, thereby improving the cutting accuracy of the metal plate and protecting the moving cutter 107 and the fixed cutter 108. After the blanking of the metal plate is completed, then the telescopic cylinder 112 contracts, and the telescopic cylinder 112 drives the lifting plate 106 and the moving cutter 107 to move upward and reset; when an irregular metal plate in the shape of an isosceles trapezoid needs to be cut, the rotating mechanism 4 drives the rotating shaft 103 to rotate, the rotating shaft 103 drives the rotating frame 102 to rotate, and the rotating frame 102 drives the moving cutter 107 and the fixed cutter 108 to rotate, thereby adjusting the cutting angle of the moving cutter 107 and the fixed cutter 108. Compared with the prior art that adjusts the cutting angle of the metal plate by changing the feeding angle of the metal plate, the present invention does not need to change the feeding angle of the metal plate, and the moving cutter 107 and the fixed cutter 108 are inside the protective housing 101, so even if there are workers moving near the cutting device, no safety hazard will be generated.

[0029] As Figures 1-5 shown, as a preferred embodiment of the present invention, an arc-shaped support plate 109 is fixed to the front side of the rotating frame 102, and a fixing plate 110 is fixed to the protective housing 101; the arc-shaped support plate 109 is slidably engaged with both the inner wall of the rotating cavity 111 and the fixing plate 110; and the upper ends of the fixed cutter 108, the arc-shaped support plate 109 and the fixing plate 110 are all on the same horizontal plane.

[0030] In an embodiment of the present invention, the arc-shaped support plate 109 and the fixing plate 110 support the metal plate to be cut. When the rotating frame 102 rotates, the rotating rotating frame 102 can drive the arc-shaped support plate 109 to rotate, so that the arc-shaped support plate 109 rotates relative to the fixing plate 110 and the protective housing 101. No matter how the rotating frame 102 drives the moving cutter 107 and the fixed cutter 108 to rotate, the arc-shaped support plate 109 and the fixing plate 110 can stably support the metal plate.

[0031] As Figures 1-3As shown, as a preferred embodiment of the present invention, the rotating sleeve 104 penetrates upward through the protective housing 101 and is fixed with a scale disk 113; a pointer 114 is fixed at the upper end of the protective housing 101, and the pointer 114 cooperates with the scale disk 113.

[0032] In the embodiment of the present invention, when the rotating frame 102 drives the moving cutter 107 and the fixed cutter 108 to rotate, the rotating frame 102 also drives the rotating sleeve 104 to rotate, the rotating sleeve 104 drives the scale disk 113 to rotate, and the rotation angle of the scale disk 113 is observed through the pointer 114, so as to facilitate understanding the cutting angle of the moving cutter 107 and the fixed cutter 108.

[0033] As Figures 1-3 shown, as a preferred embodiment of the present invention, a preloading assembly 2 is fixed on the lifting plate 106; the preloading assembly 2 includes a mounting block 201 fixed on the lifting plate 106, and a plurality of preloading rods 202 are slidably connected to the lower end of the mounting block 201; a first compression spring 203 is fixed on each of the plurality of preloading rods 202, and the upper ends of the plurality of first compression springs 203 are fixed on the mounting block 201.

[0034] In the embodiment of the present invention, when the lifting plate 106 drives the moving cutter 107 to move downward, the lifting plate 106 also drives the mounting block 201 to move downward, the mounting block 201 drives the preloading rods 202 and the first compression springs 203 to move downward. Until the lower end of the preloading rod 202 contacts the metal plate, the mounting block 201 continues to move downward against the elastic force of the first compression spring 203, so that the preloading rod 202 gradually retracts into the mounting block 201, and the first compression spring 203 pushes the preloading rod 202 downward and makes the preloading rod 202 fix the metal plate.

[0035] As Figures 1-6 shown, as a preferred embodiment of the present invention, the stopping assembly 3 includes a plurality of stopping grooves 301 annularly and evenly arranged at the upper end inside the protective housing 101; a guiding groove 302 and a track groove 306 are arranged inside the rotating frame 102, and a sliding block 303 is vertically slidably connected inside the guiding groove 302; a braking shaft 304 that cooperates with the stopping groove 301 is fixed at the upper end of the sliding block 303, a second compression spring 305 is fixed at the lower end of the sliding block 303, and the second compression spring 305 is arranged inside the guiding groove 302; a transmission block 308 is vertically slidably connected to the upper end inside the rotating frame 102, a connecting rope 307 is arranged inside the track groove 306, one end of the connecting rope 307 is fixedly connected to the transmission block 308, and the other end of the connecting rope 307 is fixedly connected to the lower end of the sliding block 303.

[0036] In an embodiment of the present invention, in the initial state, the telescopic cylinder 112 is in a contracted state, the lifting plate 106 is located above the guide shaft 105, the lifting plate 106 abuts against the lower end of the transmission block 308, the transmission block 308 pulls one end of the connecting rope 307, and the other end of the connecting rope 307 overcomes the elastic force of the second compression spring 305 and pulls the sliding block 303 downward. The sliding block 303 pulls the brake shaft 304 downward, so that the brake shaft 304 does not insert into the stop groove 301. When the lifting plate 106 drives the moving cutter 107 to move downward, the lifting plate 106 moves downward until it does not contact the transmission block 308. The second compression spring 305 pushes the sliding block 303 upward, and the sliding block 303 drives the brake shaft 304 to insert into the stop groove 301, thereby restricting the rotation of the rotating frame 102.

[0037] As Figures 1-8 shown, as a preferred embodiment of the present invention, the rotating mechanism 4 includes a second fixed frame 401 fixed to the lower end of the protective housing 101. A motor 402 is fixed on the second fixed frame 401, and a first gear 403 is fixed to the rotating end of the motor 402. The rotating shaft 103 penetrates downward through the protective housing 101 and is connected to a transmission sleeve 404 through a safety component 5. A second gear 405 is fixed on the transmission sleeve 404, and the second gear 405 meshes with the first gear 403. When the transmission sleeve 404 rotates, the safety component 5 drives the rotating shaft 103 to rotate by means of friction transmission. The safety component 5 includes isosceles trapezoidal grooves 501 uniformly and annularly arranged on the side wall of the rotating shaft 103. A plurality of sliding grooves 502 are arranged in the transmission sleeve 404, and connecting sliders 503 are slidably connected in the plurality of sliding grooves 502. One end of the connecting slider 503 extends into the isosceles trapezoidal groove 501, and the other end of the connecting slider 503 is connected to a third compression spring 504, and the third compression spring 504 is arranged in the sliding groove 502.

[0038] In an embodiment of the present invention, in the initial state, the third compression spring 504 pushes the connecting slider 503, the connecting slider 503 inserts into the isosceles trapezoidal groove 501, the motor 402 drives the first gear 403 to rotate, the first gear 403 drives the second gear 405 to rotate, the second gear 405 drives the transmission sleeve 404 to rotate, the transmission sleeve 404 drives the connecting slider 503 to rotate, and the connecting slider 503 can drive the rotating shaft 103 to rotate through the friction force with the isosceles trapezoidal groove 501. When the brake shaft 304 is inserted into the stop groove 301 and the rotating frame 102 cannot rotate, the rotating transmission sleeve 404 drives the connecting slider 503 to rotate again. At this time, the isosceles trapezoidal groove 501 will overcome the elastic force of the third compression spring 504 and push the connecting slider 503 out of the isosceles trapezoidal groove 501. At this time, a "clicking" sound will occur between the connecting slider 503 and the isosceles trapezoidal groove 501, thereby playing an alarm role, reminding the operator that the motor 402 has rotated illegally, thereby playing a protective role for the cutting device and improving the service life of the cutting device.

[0039] In the above embodiment of the present invention, a cutting device for manufacturing a blender is provided. In the initial state, the telescopic cylinder 112 is in a contracted state, the lifting plate 106 is located above the guide shaft 105, and the distance between the moving cutter 107 and the fixed cutter 108 is the largest. When in use, a metal plate is placed between the moving cutter 107 and the fixed cutter 108, the telescopic cylinder 112 extends, and under the guiding action of the guide shaft 105, the telescopic cylinder 112 drives the lifting plate 106 to move downward. The lifting plate 106 drives the moving cutter 107 and the mounting block 201 to move downward. The mounting block 201 drives the preloading rod 202 and the first compression spring 203 to move downward. The lower end of the preloading rod 202 first contacts the metal plate, and the mounting block 201 continues to move downward against the elastic force of the first compression spring 203, so that the preloading rod 202 gradually retracts into the mounting block 201. The first compression spring 203 pushes the preloading rod 202 downward and makes the preloading rod 202 fix the metal plate. Then, the moving cutter 107 moving downward cooperates with the fixed cutter 108 to cut the plate. When the rotating frame 102 moves downward and the lifting plate 106 drives the moving cutter 107 to move downward, the lifting plate 106 moves downward until it does not contact the transmission block 308. The second compression spring 305 pushes the sliding block 303 upward, and the sliding block 303 drives the braking shaft 304 to insert into the stop groove 301, thereby restricting the rotation of the rotating frame 102, avoiding the rotation of the rotating frame 102 caused by misoperation, and avoiding the horizontal movement of the moving cutter 107 and the fixed cutter 108 when the moving cutter 107 and the fixed cutter 108 cut the metal plate, thereby improving the cutting accuracy of the metal plate and protecting the moving cutter 107 and the fixed cutter 108. After the blanking of the metal plate is completed, then the telescopic cylinder 112 contracts, and the telescopic cylinder 112 drives the lifting plate 106 and the moving cutter 107 to move upward and reset;When an irregular metal plate in the shape of an isosceles trapezoid needs to be cut, in the initial state, the telescopic cylinder 112 is in a contracted state, the lifting plate 106 is located above the guide shaft 105, the lifting plate 106 abuts against the lower end of the transmission block 308, the transmission block 308 pulls one end of the connecting rope 307, and the other end of the connecting rope 307 overcomes the elastic force of the second compression spring 305 and pulls the sliding block 303 downward. The sliding block 303 pulls the brake shaft 304 downward, so that the brake shaft 304 does not insert into the stop groove 301. The third compression spring 504 pushes the connecting slider 503, and the connecting slider 503 inserts into the isosceles trapezoid groove 501. The motor 402 drives the first gear 403 to rotate, the first gear 403 drives the second gear 405 to rotate, the second gear 405 drives the transmission sleeve 404 to rotate, the transmission sleeve 404 drives the connecting slider 503 to rotate, and the connecting slider 503 can drive the rotating shaft 103 to rotate through the frictional force with the isosceles trapezoid groove 501. The rotating shaft 103 drives the rotating frame 102 to rotate, and the rotating frame 102 drives the moving cutter 107 and the fixed cutter 108 to rotate, so as to adjust the cutting angles of the moving cutter 107 and the fixed cutter 108. Compared with the existing method of adjusting the cutting angle of the metal plate by changing the feeding angle of the metal plate, the present invention does not need to change the feeding angle of the metal plate, and the moving cutter 107 and the fixed cutter 108 are inside the protective housing 101, so even if there are workers moving near the cutting device, no safety hazard will be generated; when the brake shaft 304 is inserted into the stop groove 301 and the rotating frame 102 cannot rotate, if the motor 402 rotates due to accidental touch operation, the motor 402 drives the first gear 403 to rotate, the first gear 403 drives the second gear 405 to rotate, the second gear 405 drives the transmission sleeve 404 to rotate, and the rotating transmission sleeve 404 drives the connecting slider 503 to rotate. At this time, the isosceles trapezoid groove 501 will overcome the elastic force of the third compression spring 504 and push the connecting slider 503 out of the isosceles trapezoid groove 501. At this time, a "clicking" sound will occur between the connecting slider 503 and the isosceles trapezoid groove 501, so as to play a warning role, reminding the operator that the motor 402 has rotated illegally, thereby protecting the cutting device and improving the service life of the cutting device.;
