DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1 and Figure 2A feeding device for a cardboard slotting machine includes a feeding box 1, a conveyor belt 2 for feeding is fixedly installed on one side of the feeding box 1, a discharge port 4 is opened on the side of the feeding box 1 close to the conveyor belt 2, an opening 5 connected to the discharge port 4 is opened on the side of the feeding box 1 away from the discharge port 4, and a connecting box 3 is fixedly installed on the bottom of the feeding box 1.

[0024] A pushing assembly for pushing the cardboard to move is arranged inside the connection box 3, and the pushing assembly includes two electric push rods 6 fixedly installed on the top wall of the connection box 3, and a sliding rod 7 is fixedly installed on the output end of the two electric push rods 6, and a sliding sleeve 8 is slidably installed on the surface of the sliding rod 7, and a fixing rod 9 is fixedly installed on the top of the sliding sleeve 8, and an adjusting sleeve 17 is installed outside the fixing rod 9, and a pushing plate 10 is fixedly installed on the top of the adjusting sleeve 17.

[0025] The opening 5 is provided for the movement of the push plate 10, through which the cardboard can be pushed onto the conveyor belt 2 to complete the feeding.

[0026] See also Figure 4 In this embodiment, an adjustment component for adjusting the height of the push plate 10 is provided on one side of the adjustment sleeve 17, and the adjustment component includes a mounting cover 11 fixedly mounted on the surface of the adjustment sleeve 17, and a pull rod 15 extending into the interior of the mounting cover 11 is inserted on the side of the mounting cover 11 away from the adjustment sleeve 17, and a movable block 12 is fixedly mounted on one end of the pull rod 15 located inside the adjustment sleeve 17, and a spring 14 is fixedly mounted between the inner wall of the side of the mounting cover 11 away from the adjustment sleeve 17 and the movable block 12, and the spring 14 is located outside the pull rod 15, and a clamping rod 13 extending into the interior of the fixed rod 9 is fixedly mounted on the side of the movable block 12 away from the pull rod 15, and a plurality of clamping grooves 16 are opened on the surface of the fixed rod 9, and the size of the clamping grooves 16 is adapted to the size of the clamping rod 13.

[0027] Among them, the pull rod 15 makes the clamping rod 13 move to the side away from the clamping slot 16. When the clamping rod 13 is out of the clamping slot 16, the adjustment sleeve 17 is pulled to adjust the height of the push plate 10, so that the device can adjust the height of the push plate 10 according to the thickness of the cardboard, thereby facilitating the pushing of cardboards of different thicknesses to complete the feeding, which greatly improves the practicality of the device.

[0028] See also Figure 3 In this embodiment, a driving assembly for driving the sleeve 8 to reciprocate is also provided inside the connection box 3, and the driving assembly includes a motor 19 fixedly mounted on the bottom wall of the connection box 3, and a disc 20 is fixedly mounted on the output end of the motor 19. A connecting rod 21 is rotatably mounted on one side of the upper surface of the disc 20, and the other end of the connecting rod 21 is rotatably connected to the bottom of the sleeve 8.

[0029] The starting motor 19 drives the disc 20 to rotate, thereby causing the sleeve 8 to reciprocate through the connecting rod 21, thereby driving the push plate 10 to reciprocate, and the push plate 10 can push the cardboard onto the conveyor belt 2 to complete automatic feeding.

[0030] In this embodiment, a connection groove 18 is opened on the top of the connection box 3, and the push plate 10 is slidably connected to the inner wall of the connection groove 18, and the push plate 10 is also slidably connected to the inner wall of the opening 5.

[0031] It is worth noting that when the sliding sleeve 8 moves to the rightmost side of the connecting groove 18, the pushing plate 10 is located outside the opening 5, which facilitates pushing the cardboard.

[0032] In this embodiment, a first switch 23 is fixedly installed at the bottom of the slide rod 7 and on one side of the slide sleeve 8, a first contact block 24 adapted to the first switch 23 is fixedly installed at the bottom of the slide sleeve 8, a second switch 26 is fixedly installed at the bottom of the slide rod 7 and on the other side of the slide sleeve 8, a second contact block 25 adapted to the second switch 26 is fixedly installed at the bottom of the slide sleeve 8, a controller 22 is fixedly installed on the surface of the feed box 1, and the electric push rod 6, the first switch 23 and the second switch 26 are all electrically connected to the controller 22 through wires.

[0033] Among them, when the sliding sleeve 8 moves to the left, the first contact block 24 will contact the first switch 23. At this time, the first switch 23 will transmit a signal to the controller 22, and the controller 22 will control the electric push rod 6 to start driving the sliding sleeve 8 to move downward, thereby causing the push plate 10 to move to the bottom of the discharge port 4, so that the subsequent cardboard will fall to the inner bottom wall of the feed box 1. At the same time, when the motor 19 drives the sliding sleeve 8 to reset, the second contact block 25 will contact the second switch 26, thereby resetting the electric push rod 6 through the controller 22, and then resetting the push plate 10, thereby continuing to push the second round of cardboard.

[0034] It is worth noting that when the electric push rod 6 drives the sleeve 8 to move downward, the connecting rod 21 will not move, and thus the disc 20 will not move. When the push plate 10 moves to the bottom of the discharge port 4, the sleeve 8 will not contact the connecting rod 21. The rotational connection between the connecting rod 21, the sleeve 8 and the disc 20 is a sleeve rod and a sleeve ring with a limit block. When the sleeve 8 moves downward, the sleeve ring will slide on the sleeve rod.

[0035] When the present embodiment is in use, all the cardboards to be slotted are placed inside the feed box 1. According to the thickness of the cardboard, the pull rod 15 is pulled to move the clamping rod 13 to the side away from the clamping groove 16. When the clamping rod 13 is out of the clamping groove 16, the adjusting sleeve 17 is pulled to adjust the height of the push plate 10. After adjusting to a suitable height, the motor 19 is started to drive the disc 20 to rotate, so that the sliding sleeve 8 is reciprocated through the connecting rod 21, and then the push plate 10 is driven to reciprocate. The cardboard can be pushed to the conveyor belt 2 through the push plate 10 to complete the automatic feeding. When the sliding sleeve 8 moves to the left, the first The contact block 24 will contact the first switch 23. At this time, the first switch 23 will transmit a signal to the controller 22. The controller 22 will control the electric push rod 6 to start driving the sliding sleeve 8 to move downward, thereby causing the push plate 10 to move below the discharge port 4, so that the subsequent cardboard will fall to the inner bottom wall of the feed box 1. At the same time, when the motor 19 drives the sliding sleeve 8 to reset, the second contact block 25 will contact the second switch 26, thereby resetting the electric push rod 6 through the controller 22, and then resetting the push plate 10, thereby continuing to push the second round of cardboard, greatly improving the efficiency of cardboard slotting.

[0036] The electrical components appearing in the article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device for control such as a computer, and the existing public power connection technology is not described in detail in the article.

[0037] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
