Folding machine with straight knife type folding mechanism

[0014] The present invention will be further described below with reference to the drawings and embodiments.

[0015] The reference numerals in the drawings indicate the following: 1. Knife, 2 guide rail, 3 first drive roller, 4 second drive roller, 5 first folding device, 6 second folding device, 7 third folding device, 8 fourth Folding device, 9 fifth folding device, 10 knife plate reinforcement block, 11 knife cover box side plate, 12 cover plate support assembly, 13 sliding block, 14 tapping block, 15 cylinder beam, 16 knife cover box seal Plate, 17 cylinder fixing seat, 18 cylinder.

[0016] The folding machine provided with a straight-knife folding mechanism of the present invention mainly includes a frame and five folding devices arranged on the frame. The difference from the prior art is: the five folding devices The third folding device is arranged on the platform of the rack, and the third folding device is arranged in a straight-knife slide rail device. The straight-knife slide rail device is provided with a set of driving devices and the pair of driving devices. Knife mechanism, the platform is equipped with an electric control device that cooperates with the drive device and the knife mechanism. The driving device includes a cylinder fixing seat and a cylinder arranged on the cylinder fixing seat, and a cylinder beam is arranged on one side of the cylinder. The guillotine mechanism is composed of a guillotine plate and a guillotine plate reinforcing block. The guillotine plate and the guillotine plate reinforcing block are connected by a set of guide rails and sliders, and the slider and the guide rails are slidably connected. One side of the knife plate is provided with a side plate of the knife cover box, a knife cover box sealing plate is arranged above the cylinder beam, and one side of the knife cover box sealing plate is connected with a cover plate support assembly, which is a kind of conveyor belt The divider prevents the friction between the knife cover and the conveyor belt during the transmission of the conveyor belt, and prolongs the service life of each component. A tapping pad is arranged between the cylinder beam and the connecting side of the knife cover box sealing plate.

[0017] The electric control device includes a photoelectric sensor and a control module connected with the photoelectric sensor. The control module is respectively connected with the driving device and the knife mechanism, and the photoelectric sensor is arranged on the platform. A transmission device matched with the guillotine device is provided under the platform. The transmission device is composed of two sets of transmission rollers. Each transmission roller is composed of a set of transmission shafts. The angle range between the two sets of transmission rollers is 15 —75 degrees. The angle between the two sets of drive rollers is automatically adjusted by the control module. When the machine is stopped, the two rollers are in a separate state. When the machine is turned on, the angle between the two rollers is in a close state at the position of 75° through the induction device. This ensures the flatness of the linen when folded, and this device system also solves the problem of machine jams.

[0018] In implementation, the third folding device adopts a straight-knife slide rail device, which includes a set of driving devices and a knife mechanism that cooperates with the set of driving devices. When the linen passes through the platform, the photoelectric sensor obtains the signal, and the photoelectric sensor The signal is transmitted to the control module. The control module controls the coordinated movement of the driving device and the knife device in the third folding device. The knife of the third folding device accurately feeds the linen between the first and second driving rollers. And the speed is very fast, the height of the knife can be adjusted arbitrarily according to the thickness of the linen, which is convenient and flexible. Due to the use of the guillotine mechanism to work, it avoids the problem that the three-fold air blowing mechanism of the previous folding machine cannot be fed into the subsequent two-fold due to the thickness of the linen, and the problem of manual control by adjusting the size of the air pressure is repeated. The position of the linen can be accurately sensed during the grass conveying process, making the third fold accurate and fast, laying the foundation and guarantee for the subsequent folding and conveying work.
