Description

Technical Field

[0001] This utility model relates to the field of cross-cutting machine technology, specifically a feeding device for a cross-cutting machine. Background Technology

[0002] A cross-cutting machine is a device used to cut long strips, wide strips, or rolls of materials to a predetermined length. It is widely used in many industries.

[0003] For example, a feeding device for a cross-cutting machine with authorization announcement number "CN222293143U" uses a drive motor to rotate a pushing roller. During material transport, a smoothing rod smooths out wrinkles on the material, maintaining good shearing performance. However, this feeding device relies solely on the drive motor to rotate the pushing roller, making it unable to quantitatively deliver material. Furthermore, the lack of a limiting mechanism after the material leaves the pushing roller causes deviation and scattering, affecting feeding stability. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the feeding mechanism of the feeding device for the cross-cutting machine relies solely on the drive motor to rotate the pushing roller to push the material, which cannot quantitatively convey the material. At the same time, the material in the feeding device will deviate or scatter after leaving the pushing roller due to the lack of limit, which affects the stability of the feeding. Therefore, a feeding device for the cross-cutting machine is proposed.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a feeding device for a cross-cutting machine, including a base and a first housing. The first housing is fixedly connected to the upper left side of the base. The first housing has an intermittent cardboard conveying structure inside. The second housing is fixedly connected to the upper middle part of the base. The second housing has a cardboard limiting structure inside. A curved plate is fixedly connected to the left rear end of the base.

[0007] Preferably, the cardboard intermittent conveying structure includes a first servo motor, the outer wall of which is fixedly connected to a first housing, a disk fixedly connected to the output shaft of the first servo motor, both ends of the disk's rotating shaft being rotatably connected to the first housing via bearings, a cylinder fixedly connected to the end of the disk, a locking block fixedly connected to the outer wall of the disk, the outer wall of the locking block abutting against a grooved wheel, the rotating shaft of the grooved wheel being rotatably connected to the first housing via bearings, and a first roller fixedly connected to the end of the grooved wheel's rotating shaft, the two ends of which are rotatably connected to the first housing and a bending plate via bearings, respectively.

[0008] Preferably, the two ends of the third roller are rotatably connected to the bending plate and the first housing respectively via bearings, and an electric telescopic rod is fixedly connected to the outer wall of the bending plate.

[0009] Preferably, the cardboard limiting structure includes a second servo motor, the output shaft of the second servo motor is fixedly connected to a gear, both ends of the gear's rotating shaft are rotatably connected to the second housing via bearings, both sides of the gear are meshed with a rack, the inner wall of the rack is slidably connected to a slide rod, both ends of the slide rod are fixedly connected to the second housing, the upper end of the rack is fixedly connected to a vertical rod, the outer wall of the vertical rod is slidably connected to the second housing, the upper end of the slide rod is fixedly connected to a horizontal plate, and the end of the horizontal plate is fixedly connected to a plurality of first rectangular frames, the inner walls of the first rectangular frames are rotatably connected to a second roller via bearings.

[0010] Preferably, the output end of the electric telescopic rod is fixedly connected to a second rectangular frame, and the inner wall of the second rectangular frame is rotatably connected to the fifth circular roller through a bearing.

[0011] Preferably, a cross-cutting machine is fixedly connected to the upper right side of the base, and multiple vertical plates are fixedly connected to the upper end of the second housing. The inner wall of the vertical plates is rotatably connected to the fourth roller through bearings.

[0012] The present invention provides a feeding device for a cross-cutting machine, which has the following advantages: through the cooperation of the cardboard intermittent conveying structure and the first housing, the output shaft of the first servo motor rotates to drive the disc to rotate, the disc rotates to drive the cylinder and the locking block to rotate, until the locking block no longer contacts the grooved wheel. At this time, the cylinder slides into the groove of the grooved wheel, thereby driving the grooved wheel to rotate. The rotation of the grooved wheel drives the first roller to rotate, and the rotation of the first roller moves the cardboard towards the cross-cutting machine. When the cylinder no longer contacts the grooved wheel, the locking block contacts the grooved wheel. The locking block has a limiting effect on the grooved wheel to prevent the grooved wheel from rotating on its own. Repeating the above operation can feed the cardboard into the cross-cutting machine in a quantitative manner.

[0013] Through the cooperation of the cardboard limiting structure and the second housing, the output shaft of the second servo motor rotates, driving the gear to rotate. The gear rotation drives the two racks to slide on the slide bar. The rack movement drives the two vertical rods to move inward simultaneously. The vertical rod movement drives the horizontal plate to move. The horizontal plate movement drives the two rows of second rollers to move inward until the outer wall of the second rollers is pressed against the cardboard. During this process, the fourth roller plays a supporting role to prevent the cardboard from falling, thereby limiting the cardboard and preventing it from shifting during the conveying process.

[0029] Working principle:

[0030] When using the feeding device for a cross-cutting machine:

[0031] The cardboard is placed on the first roller 306 and the fourth roller 12. Two second servo motors 501 are started. These two second servo motors 501 are connected to the same battery wire via wires. A switch on the battery is connected to an external remote control device. By controlling the opening and closing of the switch, the second servo motors 501 can be started or stopped simultaneously. The output shaft of the second servo motor 501 rotates, driving the gear 502 to rotate. The rotation of the gear 502 causes two racks 503 to slide on the slide bar 504 (e.g., ...). Figure 5 The movement of rack 503 drives the two vertical rods 505 to move inward simultaneously. The movement of vertical rods 505 drives the horizontal plate 506 to move. The movement of horizontal plate 506 drives the two rows of second rollers 508 to move inward until the outer wall of the second rollers 508 is pressed against the cardboard. At this time, the second servo motor 501 is turned off. The fourth roller 12 plays a supporting role in this process to prevent the cardboard from falling, thereby limiting the cardboard and preventing it from deviating during the conveying process.

[0032] Start the electric telescopic rod 7. The output end of the electric telescopic rod 7 moves, which drives the second rectangular frame 8 to move. The movement of the second rectangular frame 8 drives the fifth circular roller 9 to move downward until the outer wall of the fifth circular roller 9 is pressed against the cardboard. Then, turn off the electric telescopic rod 7.

[0033] When the external power supply of the first servo motor 301 is connected and the first servo motor 301 is started, the output shaft of the first servo motor 301 rotates, driving the disk 302 to rotate (e.g. Figure 4The rotating disc 302 drives the cylinder 303 and the locking block 304 to rotate until the locking block 304 no longer contacts the grooved wheel 305. At this point, the cylinder 303 slides into the groove of the grooved wheel 305, thereby driving the grooved wheel 305 to rotate. The rotation of the grooved wheel 305 drives the first roller 306 to rotate. The outer walls of the first roller 306 and the fifth roller 9 are made of rubber, which increases the friction with the cardboard and prevents the cardboard from slipping. The rotation of the first roller 306 moves the cardboard toward the cross-cutting machine 13. Furthermore, the third roller 10 supports the cardboard. When the cylinder 304 no longer contacts the grooved wheel 305, the locking block 304 contacts the grooved wheel 305. The locking block 304 limits the grooved wheel 305 and prevents it from rotating on its own. Repeating the above operation will make the cardboard... The cardboard is fed into the cross-cutting machine 13 in a fixed quantity. The cross-cutting machine 13 cuts the cardboard. The cross-cutting machine 13 is a 1400 / 1700 / 1900 computer high-speed fully automatic spiral knife cross-cutting and longitudinal cutting machine from Zhiyuan Machinery. Before cutting, the hydraulic system presses the material to prevent displacement or deformation. The spiral knife shaft rotates at high speed (e.g., the cutting speed of 500mm cardboard can reach 150m / min). The cross-cutting is achieved through the relative movement of the blade and the material. The cut is smooth and burr-free. After cutting, the finished product is transported to the external collection box through the discharge port on the right. To further explain, after the left side of the cardboard leaves the first roller 306, the next cardboard is placed on the surface of the first roller 306 and the third roller 10. The next cardboard can push the previous cardboard to move to the right.
