Description

Technical Field

[0001] The utility model relates to the technical field of cutting dies, and particularly relates to an automatic deviation rectifying cutting die. Background Technique

[0002] An automatic deviation rectifying cutting die is a device used in the automated cutting process, usually for processing materials (such as cardboard, fabric, plastic, etc.) in the manufacturing industry. This die can detect the position and deviation of the material through built-in sensors and control systems, and accordingly adjust the operation of the cutting machine to ensure the accuracy and quality of the final product.

[0003] In the Chinese patent "A cardboard cutting machine with an automatic deviation rectifying component", the authorized announcement number is "CN219563203U". Through a telescopic cylinder, a knife plate, a spring, a guiding movable rod and a positioning pressing plate, when the cardboard cutting knife cuts downward, the positioning pressing plate is made to abut against the cardboard for deviation rectifying cutting, thereby ensuring the cutting accuracy of the cutting machine for the cardboard.

[0004] In the above deviation rectifying cutting of thick cardboard, the cutting knife needs to cut a relatively long distance downward, which easily causes the spring to be over-pressed, resulting in unstable abutting force of the positioning pressing plate against the thick cardboard, and further resulting in deviation of the cutting position, thus affecting the cutting accuracy of the cutting die for the cardboard.

[0005] Therefore, an automatic deviation rectifying cutting die is proposed to solve the above problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide an automatic deviation rectifying cutting die to solve the above problems, and improve the problem that relying only on the spring easily causes unstable abutting of the positioning pressing plate against the thick cardboard.

[0007] The utility model realizes the above purpose through the following technical solutions. An automatic deviation rectifying cutting die includes: a conveying table, the inner wall of the conveying table is fixedly connected with a cylinder, and the bottom end of the cylinder is fixedly connected with a cutting knife; a deviation rectifying mechanism, the deviation rectifying mechanism for rectifying the cardboard during cutting is arranged at the bottom of the cutting knife; wherein, the deviation rectifying mechanism includes two anti-pressure cylinders fixedly connected to the inner wall of the cutting knife, the inner wall of the anti-pressure cylinder is slidably connected with an anti-pressure frame, the inner wall of the anti-pressure frame is slidably connected with a positioning frame, the inner wall of the positioning frame is rotatably connected with a roller, the inner bottom wall of the anti-pressure cylinder is fixedly connected with a first spring, the top end of the first spring is fixedly connected to the bottom end of the anti-pressure frame, and a deviation rectifying component is arranged at the bottom of the cutting knife. By using the roller, the movement limit of the cardboard on the conveying table is realized, ensuring that the cardboard will not deviate during conveying.

[0008] Preferably, the deviation rectifying assembly includes a liquid storage frame fixedly connected to one side of the conveying table. A liquid pushing block is slidably connected to the inner wall of the liquid storage frame, and the bottom end of the liquid storage frame communicates with the inner top wall of the anti-pressure cylinder. By using the hydraulic oil in the anti-pressure cylinder, the liquid storage frame, the anti-pressure frame and the first spring, the roller is pressed against the cardboard evenly, thereby ensuring the stability of rectifying the cardboard and thus ensuring the cutting accuracy of the cutting die for the cardboard.

[0009] Preferably, a second spring is fixedly connected to the top of the positioning frame, and the top end of the second spring is fixedly connected to the inner top wall of the anti-pressure frame.

[0010] Preferably, a one-way air outlet pipe is communicated with the inner top wall of the anti-pressure frame. By using the second spring and the one-way air outlet pipe, the gas in the anti-pressure frame is discharged through the one-way air outlet pipe and the second spring is compressed, thereby ensuring that the roller is pressed against the cardboard evenly and improving the effect of rectifying the cardboard.

[0011] Preferably, a one-way air inlet pipe is communicated with the inner top wall of the anti-pressure frame. By using the second spring and the one-way air inlet pipe, the outside air flows into the anti-pressure frame through the one-way air inlet pipe, ensuring that there is an appropriate amount of gas in the anti-pressure frame.

[0012] Preferably, a third spring is fixedly connected to the inner wall of the liquid storage frame, and the other end of the third spring is fixedly connected to the front end of the liquid pushing block. By using the third spring, the liquid pushing block moves in the liquid storage frame, and then the liquid in the liquid storage frame is pushed into the anti-pressure cylinder, ensuring that there is an appropriate amount of liquid in the anti-pressure cylinder.

[0013] Preferably, a stop block is fixedly connected to the inner wall of the liquid storage frame. By using the stop block, the moving position of the liquid pushing block is restricted, preventing the front end of the liquid pushing block from moving to the drain pipe at the bottom of the liquid storage frame.

[0014] Preferably, the roller is made of rubber. By using the rubber roller, the friction between the roller and the cardboard is increased, thereby ensuring the stability of the cardboard during conveying and cutting.

[0015] The beneficial effects of the utility model are as follows:

[0016] By using the roller, the movement of the cardboard on the conveying table is limited, ensuring that the cardboard does not shift during conveying. By using the hydraulic oil in the anti-pressure cylinder, the liquid storage frame, the anti-pressure frame and the first spring, the roller is pressed against the cardboard evenly, thereby ensuring the stability of rectifying the cardboard and thus ensuring the cutting accuracy of the cutting die for the cardboard;

[0017] By using the second spring and the one-way air outlet pipe, the gas in the anti-pressure frame is discharged through the one-way air outlet pipe and the second spring is compressed, thereby ensuring that the roller is pressed against the cardboard evenly and improving the effect of rectifying the cardboard.

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] During specific implementation: As Figures 1-4 shown, an automatic deviation rectifying cutting die includes: a conveying table 1, an air cylinder 2 is fixedly connected to the inner wall of the conveying table 1, and a cutting knife 3 is fixedly connected to the bottom end of the air cylinder 2; a deviation rectifying mechanism 4, a deviation rectifying mechanism 4 for rectifying the cardboard during cutting is arranged at the bottom of the cutting knife 3; wherein, the deviation rectifying mechanism 4 includes two anti-pressing cylinders 41 fixedly connected to the inner wall of the cutting knife 3, an anti-pressing frame 42 is slidably connected to the inner wall of the anti-pressing cylinder 41, a positioning frame 43 is slidably connected to the inner wall of the anti-pressing frame 42, a roller 44 is rotatably connected to the inner wall of the positioning frame 43, a first spring 45 is fixedly connected to the inner bottom wall of the anti-pressing cylinder 41, and the top end of the first spring 45 is fixedly connected to the bottom end of the anti-pressing frame 42. A deviation rectifying component 46 is arranged at the bottom of the cutting knife 3. The roller 44 is made of rubber. The deviation rectifying component 46 includes a liquid storage frame 461 fixedly connected to one side of the conveying table 1, a liquid pushing block 462 is slidably connected to the inner wall of the liquid storage frame 461, the bottom end of the liquid storage frame 461 communicates with the inner top wall of the anti-pressing cylinder 41, a stop block 467 is fixedly connected to the inner wall of the liquid storage frame 461, and a third spring 466 is fixedly connected to the inner wall of the liquid storage frame 461, and the other end of the third spring 466 is fixedly connected to the front end of the liquid pushing block 462.

[0025] Hydraulic oil is stored in the anti-pressure cylinder 41 and the liquid storage frame 461 . The inner bottom wall of the liquid storage frame 461 is connected with a drain pipe, and the bottom end of the drain pipe is connected to the inner top wall of the anti-pressure cylinder 41 .

[0026] Two electric push rods are fixedly connected to the top of the conveyor platform 1, and the telescopic ends of the electric push rods are fixedly connected to a moving frame. Pulleys are rotatably connected to both sides of the inner wall of the moving frame, and a belt is transmission-connected between the surfaces of the two pulleys. A first servo motor is fixedly connected to the top of the moving frame, and the output shaft of the first servo motor is fixedly connected to the top of one of the pulleys. Two deviation detection sensors are fixedly connected to the top of the conveyor platform 1, and an auxiliary disk is rotatably connected to the inner wall of the conveyor platform 1. A second servo motor is fixedly connected to one end of the auxiliary disk, and the second servo motor is fixedly connected to the rear end of the conveyor platform 1.

[0027] The conveyor table 1 conveys the cardboard, and the deviation detection sensor detects whether the cardboard being conveyed has deviation. If deviation occurs, the electric push rod and the first servo motor will be automatically turned on, and the output shaft of the first servo motor rotates through the corresponding pulley to drive the belt transmission. The telescopic end of the electric push rod moves to drive the moving frame and the belt to move, so that the transmission belt contacts the surface of the cardboard, and the cardboard is initially corrected for transmission. The second servo motor is manually turned on, and the output shaft of the second servo motor rotates to drive the auxiliary disk to rotate. The rotating auxiliary disk limits the conveying of the cardboard. When correction is not needed, the electric push rod, the first servo motor and the second servo motor are automatically turned off.

[0028] It should be noted that the conveyor platform 1, cylinder 2, electric push rod, first servo motor, deviation detection sensor, second servo motor, etc. in the above description are all devices with relatively mature application of existing technologies. The specific models can be selected according to actual needs. At the same time, the conveyor platform 1, cylinder 2, electric push rod, first servo motor, deviation detection sensor, and second servo motor can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0029] When it is necessary to cut the thick cardboard, the cylinder 2 is manually opened, and the bottom end of the cylinder 2 moves downward to drive the cutting knife 3 to move downward, and the cutting knife 3 moves downward to drive the correcting mechanism 4 to move downward, so that the roller 44 contacts the thick cardboard. At this time, the cutting knife 3 drives the anti-pressure cylinder 41 to continue to move downward, so that the hydraulic oil in the anti-pressure cylinder 41 is pushed into the liquid storage frame 461 and the first spring 45 is stretched, so that the roller 44 will not continue to press down on the thick cardboard, so that the roller 44 is pressed against the thick cardboard, and the cutting knife 3 cuts the thick cardboard accurately. When it is not necessary to cut the thick cardboard, the cylinder 2 and the conveying platform 1 are manually closed.

[0030] like Figure 4As shown in the figure, the top of the positioning frame 43 is fixedly connected to a second spring 463. The top end of the second spring 463 is fixedly connected to the inner top wall of the anti-pressure frame 42. The inner top wall of the anti-pressure frame 42 is communicated with a one-way air outlet pipe 464, and the inner top wall of the anti-pressure frame 42 is communicated with a one-way air inlet pipe 465.

[0031] The one-way air outlet pipe 464 includes a first one-way valve and an exhaust pipe. The first one-way valve is fixed on the surface of the exhaust pipe. The first one-way valve is used to block the outside air from entering the anti-pressure frame 42 through the exhaust pipe. The one-way air inlet pipe 465 includes a second one-way valve and a guide pipe. The second one-way valve is fixed on the surface of the guide pipe. The second one-way valve is used to block the gas in the anti-pressure frame 42 from being discharged through the guide pipe.

[0032] When the anti-pressure cylinder 41 moves down to a certain position, the cutting knife 3 still needs to move down. At this time, the cutting knife 3 moves down to push the anti-pressure cylinder 41 and the anti-pressure frame 42 to move down. The anti-pressure frame 42 moves down in the positioning frame 43, so that the gas in the anti-pressure frame 42 is discharged through the one-way air outlet pipe 464 and the second spring 463 is compressed, so that the roller 44 will not press down on the cardboard excessively, and the roller 44 presses down on the cardboard stably with balanced pressure.

[0033] When the present utility model is in use, the cylinder 2 is manually opened. The bottom end of the cylinder 2 moves down to drive the cutting knife 3 and the deviation correction mechanism 4 to move down, so that the roller 44 abuts against the cardboard. At this time, the cutting knife 3 drives the anti-pressure cylinder 41 to continue to move down, so that the hydraulic oil in the anti-pressure cylinder 41 is pushed into the liquid storage frame 461 and the first spring 45 is stretched, so that the roller 44 will not continue to press down on the cardboard. When the anti-pressure cylinder 41 moves down to a certain position, the cutting knife 3 still needs to move down. At this time, the cutting knife 3 moves down to push the anti-pressure cylinder 41 and the anti-pressure frame 42 to move down. The anti-pressure frame 42 moves down in the positioning frame 43, so that the gas in the anti-pressure frame 42 is discharged through the one-way air outlet pipe 464 and the second spring 463 is compressed, so that the roller 44 will not press down on the cardboard excessively, and the roller 44 presses down on the cardboard stably with balanced pressure. The cutting knife 3 precisely cuts the cardboard. When it is not necessary to cut the cardboard, the cylinder 2 and the conveying table 1 are manually closed.

[0034] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. The narrative way of this specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
