Description

Technical Field

[0001] This utility model belongs to the field of cardboard box production technology, and specifically relates to a paper feeding device for a paper slitting machine used in cardboard box production. Background Technology

[0002] A paper slitting machine is a common piece of equipment used to produce and process cardboard boxes. It plays a significant role in improving the efficiency of cardboard box factories. A paper slitting machine typically includes a loading platform on which the cardboard to be slitted is placed. The cardboard is then manually fed into the paper slitting machine in sequence for the slitting process.

[0003] Most existing paper slitting machines rely on manual feeding of cardboard. This manual feeding increases workload, is time-consuming and labor-intensive, and lacks control over the cardboard's position, leading to easy displacement and poor slitting results. During the feeding process, cardboard debris can scatter into the machine, requiring manual cleaning by stopping the cardboard transport, which is inefficient. Therefore, a paper feeding device for cardboard box production is proposed to solve these problems. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides a paper feeding device for a paper slitting machine in carton production. It solves the problems of manual paper feeding increasing the workload, being time-consuming and labor-intensive, not restricting the position of the cardboard, causing the cardboard to easily shift, resulting in poor paper slitting effect, and the fact that cardboard debris will drift into the inside of the device, requiring manual cleaning by stopping the cardboard transport.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a paper feeding device for a paper slitting machine in carton production, comprising a protective shell, a motor mounted on one side of the surface of the protective shell, a second rotating shaft connected to the output end of the motor, a rotating roller connected to one end of the second rotating shaft, a driven rotating shaft connected to both ends of the inner surface of the protective shell, a driven rotating roller connected to one end of the driven rotating shaft, a conveyor belt provided on the surface of the rotating roller, and one end of the inner surface of the conveyor belt abutting against the surface of the driven rotating roller, an electric hydraulic push rod mounted on the top of the inner surface of the protective shell, a concave connecting plate connected to one end of the electric hydraulic push rod, five sets of first rotating shafts connected to both sides of the inner surface of the concave connecting plate, pressure rollers connected to one end of the first rotating shafts, and the pressure rollers arranged in an array, and a dust collection box provided at the center of the top of the protective shell.

[0006] Preferably, a vacuum cleaner is installed on one side of the vacuum box, and vacuum pipes are connected to both sides inside the vacuum cleaner. One end of the vacuum pipe is connected to a vacuum head, and the other end of the vacuum head is connected to the top of the protective shell.

[0007] Preferably, the surface of the conveyor belt has multiple sets of anti-slip grooves, and the multiple sets of anti-slip grooves are arranged in an array.

[0008] Preferably, through holes are provided on both sides of the surface of the concave connecting plate, and ion wind bars are connected to both sides of the bottom of the concave connecting plate.

[0009] Preferably, each of the four corners of the bottom of the protective shell is fixedly connected to a support leg, and one end of each support leg is equipped with a caster wheel.

[0010] Preferably, multiple sets of support rollers are connected to both sides inside the protective shell. The support rollers are arranged in an array, and the surface of the support rollers is in contact with the inner surface of the conveyor belt.

[0011] Preferably, a return spring is connected to one end of the surface of the electro-hydraulic push rod, and the return spring is located between the electro-hydraulic push rod and the concave connecting plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The paper to be fed is placed on the surface of the conveyor belt. The motor drives the second rotating shaft and the rotating roller to rotate, thereby moving the conveyor belt forward. The conveyor belt continuously transports the cardboard. The worker only needs to place the cardboard on the surface of the conveyor belt and limit its position. There is no need for manual paper feeding, which can reduce the workload of manual paper feeding, reduce working time, and reduce labor costs. The concave connecting plate and the pressure roller are pushed down by the electric hydraulic push rod to limit the position of the paper. When the conveyor belt moves the cardboard, the pressure roller rotates along the first rotating shaft to limit the position of the paper and prevent the cardboard from being placed at an angle, which would result in poor paper separation. The vacuum cleaner drives the vacuum pipe and vacuum head to suck the debris generated by the cardboard into the vacuum box. There is no need to stop the manual cleaning of the cardboard, which improves work efficiency. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-7 The present invention provides the following technical solution: a paper feeding device for a paper slitting machine in carton production, comprising a protective shell 1, a motor 3 installed on one side of the surface of the protective shell 1, a second rotating shaft 15 connected to the output end of the motor 3, a rotating roller 16 connected to one end of the second rotating shaft 15, a driven rotating shaft 19 connected to both ends of the inner surface of the protective shell 1, a driven rotating roller 18 connected to one end of the driven rotating shaft 19, a conveyor belt 6 provided on the surface of the rotating roller 16, and one end of the inner surface of the conveyor belt 6 abutting against the surface of the driven rotating roller 18, an electric hydraulic push rod 9 installed on the top of the inner surface of the protective shell 1, a concave connecting plate 8 connected to one end of the electric hydraulic push rod 9, five sets of first rotating shafts 13 connected to both sides of the inner surface of the concave connecting plate 8, a pressure roller 12 connected to one end of the first rotating shaft 13, and the pressure rollers 12 are arranged in an array, and a dust collection box 2 is provided at the center of the top of the protective shell 1.

[0025] In this embodiment, the conveyor belt 6, together with the rotating roller 16 and the driven roller 18, forms a closed-loop rotation. The dual-roller drive ensures smooth transmission. The anti-slip groove 17 is designed to increase friction, prevent paper from slipping and shifting position, and improve the paper separation accuracy of the paper separator.

[0026] In this embodiment, multiple sets of pressure rollers 12 are distributed to apply pressure to the surface of the paperboard, avoiding uneven pressure on the paperboard surface during the paperboard transmission process, preventing local deformation of the paperboard, reducing paperboard waste, and lowering production costs.

[0027] In this embodiment, the ion air bar 14 blows out charges to eliminate the electrostatic adsorption of the paper, and works with the pressure roller 12 to flatten the cardboard and improve the neatness of the cardboard stack.

[0028] In this embodiment, the support roller 7 provides auxiliary support to the conveyor belt 6, disperses the load on the conveyor belt 6, reduces the wear rate of the conveyor belt 6, and improves the service life of the conveyor belt 6.

[0029] In this embodiment: the corresponding support leg 4 can improve the stability of the device, and the caster wheel 5 can make it easy for the staff to move the device to the corresponding working position, making it convenient for the staff to operate and reducing manpower consumption.

[0030] In this embodiment, the vacuum cleaner 20 drives the vacuum pipe 21 and the vacuum head 22 to suck the paper scraps on the surface of the cardboard into the vacuum box 2, avoiding the paper scraps remaining inside the protective shell 1 and making it inconvenient for workers to clean. This allows the device to work continuously without manual cleaning, reducing labor costs and improving work efficiency.

[0031] The working principle and usage process of this utility model are as follows: After the utility model is installed, move the device to the corresponding position, place the cardboard to be fed onto the surface of the conveyor belt 6, start the ion air bar 14, start the electric hydraulic push rod 6, which pushes the concave connecting plate 8 downward, thereby pushing the pressure roller 12 downward. After the pressure roller 12 contacts the surface of the cardboard, close the electric hydraulic push rod 9. The position of the cardboard is restricted by the contact between the pressure roller 12 and the surface of the cardboard and the conveyor belt 6. Start the vacuum cleaner 20, start the motor 3, which drives the second rotating shaft 15 to rotate, thereby driving the rotating roller 16 to rotate, and then... The conveyor belt 6 drives forward, and during the transmission process, the conveyor belt 6 drives the roller 18 to rotate along the shaft 19, thereby driving the cardboard forward. As the cardboard moves forward, the ion air bar 14 blows out charges to remove the static electricity generated on the surface of the cardboard. The debris generated by the cardboard is sucked into the dust collection box 2 by the suction head 22 and the suction pipe 21. After the conveyor belt 6 delivers the cardboard into the paper separator, the motor 3 is turned off, the cardboard is repositioned and restrained. All electrical equipment in this device is powered by an external power source, and all motors or electric push rods in this paper are controlled by a PLC control system.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
