[0001] The invention relates to the technical field of sponge production equipment, in particular to a full-automatic sponge punching machine. Background Art

[0002] Sponge has a wide range of applications. In the sponge production process, the punching machine is an indispensable processing equipment. After the sponge is foamed and formed, the punching machine is needed to punch holes at the axis of the cylindrical sponge, and then the axis is inserted. The cylindrical sponge after the axis is inserted is sliced ​​by the sponge circular cutting machine to finally obtain a sheet of sponge.

[0003] When the existing sponge punching machine is in use, the cylindrical sponge to be punched on the conveyor belt falls on the sponge positioning table, and the cylindrical sponge directly changes from a vertical state to a horizontal state. The sponge positioning table is driven by an external power to slide forward along the base, and the drilling device starts working at the same time to punch holes in the cylindrical sponge, and then the punched cylindrical sponge is removed from the sponge positioning table.

[0004] The above-mentioned sponge punching machine has the following problems during operation: 1. The cylindrical sponge falls directly from the conveyor belt and rotates 90 degrees. Affected by gravity and inertia, the collision force between the falling sponge and the sponge positioning table is large, the sponge is easily worn or damaged, and it is difficult to ensure that the sponge falls accurately in the appropriate position. 2. The cylindrical sponge and the positioning table are large in size, and their moving feeding mechanism is large and cumbersome and difficult to control. 3. The sponge pushing movement and drilling start and stop of the existing sponge punching machine are completely manually controlled by the staff, which has high labor intensity and low work efficiency. Summary of the invention

[0005] In view of the problems existing in the prior art, the present invention provides a fully automatic sponge punching machine, which adopts a technical solution comprising a sponge transfer device located in front of a conveyor belt and a sponge positioning device, a drilling device and a control console located on one side of the sponge transfer device. The sponge transfer device comprises a transfer base and a connecting frame and a placing table located above the transfer base. The rear end of the connecting frame is hinged on the transfer base. A first cylinder is hingedly connected between the connecting frame and the transfer base, which is used to make the placing table on the connecting frame present an inclined state with the front higher and the rear lower. The placing table is V-shaped in cross section, comprising two left and right inclined plates, wherein the inclined plate on one side is hingedly connected to the connecting frame, and a second cylinder is hingedly connected between the inclined plate on the other side and the connecting frame, which is used to make the placing table present a side tilting state. A first sensor for detecting sponges is provided on the placing table. The sponge positioning device is located on the dumping side of the placing table. The sponge positioning device comprises a positioning base, a fixed guide plate fixed on the positioning base and a movable guide plate hinged on the positioning base. The fixed guide plate is located on a side close to the placing table and is sloped, which is used to dump the sponge from the placing table. Guided to the movable guide plate, the cross-section of the movable guide plate is obtuse-angled V-shaped, including a support plate and an inclined side plate, a third cylinder is hingedly connected between the support plate and the positioning base, used to make the movable guide plate tilt outward, and a second sensor for detecting the sponge is provided on the positioning base and passes through the support plate; the drilling device includes a drilling bracket and a two-way push motor and a drilling motor installed on the drilling bracket, the drilling bracket is provided with a slide rail, and a movable motor base is provided on the slide rail, the drilling motor is fixed on the motor base, and a hollow drill rod is connected to the output end of the drilling motor, the two-way push motor is fixed on the drilling bracket, and the motor base is driven to move by a transmission mechanism, and a first travel switch and a second travel switch arranged on the front and rear sides of the drilling motor are provided on the drilling bracket, and the motor base and the first travel switch and the second travel switch are all blocked and matched, and are used to control the steering and start and stop of the two-way push motor, the first sensor, the second sensor, the first travel switch and the second travel switch are all connected to the console signal, and the console is electrically connected to the first cylinder, the second cylinder, the third cylinder, the two-way push motor, and the drilling motor.

[0006] As a preferred technical solution of the present invention, a guide sleeve for allowing the drill rod to pass through is fixed on the drilling bracket.

[0007] As a preferred technical solution of the present invention, the transmission mechanism is a chain sprocket mechanism.

[0008] As a preferred technical solution of the present invention, a second cylinder is hingedly connected below the two inclined plates of the placing table.

[0009] The beneficial effects of the present invention are as follows: in the present invention, the sponge placed vertically on the transmission belt becomes inclined after falling through the placing table in the sponge transfer device which can tilt forward and backward and tilt left and right, and then becomes flat and dumped into the sponge positioning device. The sponge transfer device is provided for transition, and the sponge can be accurately positioned while the impact force of the falling sponge is weakened. In the drilling device, the drilling motor feeds forward while rotating the drilling hole, and the structure is simple and easy to control, thereby avoiding other wear when punching holes in the sponge. The punched sponge is moved through the V-shaped movable guide plate in the sponge positioning device, so that it rolls out along the inclined side plate without manual removal. The sensors, travel switches, cylinders, motors, control consoles, etc. can be used to realize full-automatic sponge punching, which is simple to operate and has low labor intensity for workers, making the punching process more efficient.

[0010] Furthermore, two second cylinders on the left and right are hinged between the bottom of the placing table and the connecting frame, so that after detecting the sponge, the placing table will tilt to one side, and when the sponge is detected again, it can tilt to the other side; and when tilting, the hinge point on the top of the opposite cylinder is used as the fulcrum, which can simplify the mechanism and facilitate use.

[0026] In this embodiment, a guide sleeve 504 for the drill rod 505 to pass through is fixed on the drilling support 501 to play a supporting and guiding role.

[0027] The lower parts of the two inclined plates of the placing platform 303 are both hingedly connected with the second cylinder 305, and the left and right sides of the sponge transfer device 3 are both provided with sponge positioning devices 4, so that the placing platform 303 can be tilted to the left and to the right.

[0028] The transmission mechanism between the bidirectional push motor 503 and the motor base 506 is a chain sprocket mechanism.

[0029] The first sensor and the second sensor are piezoelectric sensors.

[0030] The working principle of the present invention is as follows: the cylindrical sponge 1 to be punched on the conveyor belt 2 is placed vertically, and as the conveyor belt 2 moves forward, it falls on the inclined placing table 303 with a high front and a low back of the sponge transfer device 3 in front, the first sensor on the placing table 303 detects the sponge 1, and transmits a signal to the control console 6, the control console 6 controls the first cylinder 304 to contract, the connecting frame 302 and the placing table 303 to be leveled, and then controls the second cylinder 305 on the left side of the placing table 303 to open, so that the placing table 303 tilts to the right on the connecting frame 302, and the sponge falls on the supporting plate of the movable guide plate 403 along the fixed guide plate 402 of the sponge positioning device 4, the second sensor 405 at the supporting plate detects the sponge 1, and transmits a signal to the control console 6 , the control console 6 controls the two-way pushing motor 503 and the drilling motor 502 to start, the drill rod 505 rotates, and at the same time, the motor base 506 moves the drilling motor 502 forward to punch holes in the sponge on the sponge positioning device 4, and the sponge shaft in the drill rod is discharged from the rear end. When the motor base 506 moves forward until it touches the first stroke switch 507 on the front side, the drilling is completed, and the control console 6 controls the two-way pushing motor 503 to reverse and controls the motor base 506 to move backward. When the motor base 506 moves backward until it touches the second stroke switch, the two-way pushing motor 503 stops rotating, controls the third cylinder 404 to open, and dumps the punched sponge on the movable guide plate 403 outward, and a working cycle ends. When the first sensor on the holding table 303 detects the sponge 1 again, the first cylinder 304 drives the holding table 303 to be leveled, and then the second cylinder 305 on the right side of the holding table 303 is opened, so that the holding table 303 on the connecting frame 302 tilts to the left, and the sponge is sent to the sponge positioning device 4 on the left for punching.
