Specific implementation manners

[0030] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the specific implementation manners of the present utility model will be described in detail below with reference to the accompanying drawings of the specification.

[0031] Embodiment 1

[0032] Refer to Figures 1-6, which is the first embodiment of the present utility model, provides a corrugated cardboard production and cutting device. This corrugated cardboard production and cutting device includes a cutting table 1 and a cutting support 2. The cutting support 2 is fixedly installed on the top of the cutting table 1. A processing component 3 and a conveyor 4 are arranged on the top of the cutting table 1. The processing component 3 is located at the bottom of the cutting support 2. The processing component 3 includes a quantitative component 31. The quantitative component 31 includes side baffles 311. The side baffles 311 are fixedly installed on one side of the cutting table 1. A threaded slider 312 is arranged inside the side baffles 311. A power arm 313 is movably connected inside the threaded slider 312. One end of the power arm 313 is hinged to a transmission plate 314. The transmission plate 314 is located on the top of the side baffles 311. A pressing plate 315 is arranged at the end of the transmission plate 314 away from the power arm 313. The pressing plate 315 is movably connected inside the cutting support 2. A pneumatic push rod 316 is fixedly installed on the top of the cutting support 2. A cutting tool 317 is arranged at the bottom of the output shaft of the pneumatic push rod 316. Between the pressing plate 315, the pneumatic push rod 316 and the cutting tool 317, the included angle between the side baffles 311 and the cutting table 1 is ninety degrees. And when cutting the board, one side of the cardboard must be attached to the side baffles 311. The power arm 313 is hinged in the threaded slider 312 and deflects around the threaded slider 312 when the cardboard pushes the power arm 313. The transmission plate 314 can approach the bottom of the pneumatic push rod 316 through the deflected power arm 313 and be located on the top of the cutting tool 317. When the output shaft of the pneumatic push rod 316 reaches the maximum extension length, it is exactly located on the top of the cutting tool 317. And when the pressing plate 315 does not deflect, it does not cause extrusion to the cutting tool 317. When the pressing plate 315 deflects, the pneumatic push rod 316 squeezes the cutting tool 317 through the pressing plate 315 to cut the cardboard on the cutting table 1. And the cutting length is the distance between the cutting tool 317 and the threaded slider 312. Thus, after determining the cutting length, the cardboard can be accurately cut without marking multiple times.

[0033] Equidistantly arranged positioning holes 318 are formed inside the transmission plate 314. The transmission plate 314 is hinged to the power arm 313 through the positioning holes 318. The threaded slider 312 is threadedly connected to the side baffles 311 through an adjusting screw 319. The positioning holes 318 can change the initial inclination angle of the power arm 313 and cooperate with the threaded slider 312 to rotate through the adjusting screw 319 and move in the groove of the side baffles 311, so as to meet the cutting requirements for cardboard of different lengths.

[0034] The processing component 3 includes a protective part 32. The protective part 32 includes a tool holder 321. The cutting tool 317 is movably connected to the top of the cutting table 1 through the tool holder 321. Auxiliary shafts 322 are arranged on both sides of the tool holder 321. Buffer springs 323 are also arranged on both sides of the cutting tool 317. The buffer springs 323 are located between the tool holder 321 and the cutting table 1. The tool holder 321 can move vertically with the cutting table 1 in the groove of the cutting support 2 under the restriction of the auxiliary shafts 322. When the tool holder 321 is squeezed by the pressing plate 315, the buffer springs 323 can provide protection and push the cutting tool 317 connected to the tool holder 321 to reset its height when the cutting is completed, waiting for the next cutting.

[0035] The protective part 32 further includes a column 324. The pressing plate 315 is hinged to the top of the tool holder 321 through the column 324. A lifting spring 325 is arranged at the top of the column 324. The column 324 is located at the bottom of the pressing plate 315. When the pressing plate 315 rotates, it takes the column 324 as the center. When the pressing plate 315 is squeezed by the pneumatic push rod 316, the lifting spring 325 can provide protection and push the pressing plate 315 to reset its height when the cutting is completed.

[0036] The pressing plate 315 is hinged to the outside of the side baffle 311 through a connecting rod 326. A return spring 327 is arranged on the outside of the connecting rod 326. When the pressing plate 315 deflects, the return spring 327 can provide protection and push the pressing plate 315 connected to the connecting rod 326 to reset its angle when the cutting is completed, waiting for the next cutting.

[0037] The conveying part 4 includes a lifting support 41. The lifting support 41 is fixedly installed on the top of the cutting table 1 and is located on the side of the cutting support 2 away from the side baffle 311. A driving seat 42 is arranged inside the lifting support 41. An opening through which the cardboard can pass is arranged in the lifting support 41. A servo motor driven by electricity is arranged in the driving seat 42.

[0038] The output shaft of the driving seat 42 is connected with a feeding roller 43. The feeding rollers 43 are symmetrically distributed on both sides of the cutting table 1. Blocks are arranged at both ends of the feeding roller 43. The blocks in the feeding roller 43 are threadedly connected with the lifting support 41 through a lifting screw rod 44. The feeding roller 43 can be driven to rotate by the output shaft in the driving seat 42, and the other group of feeding rollers 43 rotates through the friction with the cardboard. When the lifting screw rod 44 rotates, the blocks in the feeding roller 43 can move in the groove of the lifting support 41, so as to complete the adjustment of the height of the feeding roller 43 to meet the feeding requirements of corrugated cardboard with different thicknesses.

[0039] During use, by rotating the lifting screw rod 44, the clamping blocks on both sides of the feeding roller 43 move in the grooves of the lifting bracket 41, changing the height of the corresponding feeding roller 43 in the lifting bracket 41 to adapt to the transportation of corrugated cardboard of different thicknesses. The output shaft in the driving seat 42 drives the connected feeding roller 43 to rotate, causing the cardboard on the cutting table 1 to move along the surface of the cutting table 1 towards the cutting bracket 2. The other set of feeding rollers 43 rotates through friction with the cardboard, cooperating with the feeding roller 43 connected to the driving seat 42 to meet the conveying requirements of the corrugated cardboard to be cut. At the same time, the cutting position on a set of cardboard is marked. When the cardboard is restricted by the side baffle 311 and squeezes the power arm 313 to deflect the threaded slider 312, the articulated transmission plate 314 approaches the side of the pressing plate 315 and pushes the pressing plate 315 to deflect towards the side close to the pneumatic push rod 316, making the pressing plate 315 located on top of the cutting tool 317. After the pressing plate 315 deflects, the extended pneumatic push rod 316 squeezes the cutting tool 317 through the pressing plate 315 to cut the cardboard on the cutting table 1, and the cutting length is the distance between the cutting tool 317 and the threaded slider 312. Thus, after determining the cutting length, the cardboard can be accurately cut without marking multiple times. During this process, when the tool holder 321 is squeezed by the pressing plate 315, the buffer spring 323 provides protection and at the end of cutting, pushes the cutting tool 317 connected to the tool holder 321 to reset its height. When the pressing plate 315 is squeezed by the pneumatic push rod 316, the lifting spring 325 provides protection and at the end of cutting, pushes the pressing plate 315 to reset its height. When the pressing plate 315 deflects, the reset spring 327 provides protection and at the end of cutting, pushes the pressing plate 315 connected to the connecting rod 326 to reset its angle, waiting for the next cut, thereby realizing the automatic reset of the device and ensuring operation safety.
