Description

Technical Field

[0001] This utility model relates to the field of feeding equipment technology, specifically to a white card feeding device. Background Technology

[0002] Currently, in the production of packaging boxes, to improve product convenience and aesthetics, decorative elements such as white cardboard, plastic, leather, or metal are typically pasted inside the gray board windows of the cardboard box. These materials not only enhance the product's appearance but also protect the contents. However, existing processes largely rely on manual operation, which is slow, cannot be automated, and increases overall production costs due to the need for significant manual labor. Therefore, we propose a white cardboard feeding device. Utility Model Content

[0003] In view of the shortcomings of the existing technology, this utility model provides a white card feeding device to solve the problems existing in the prior art. To achieve the above objectives, this utility model provides the following technical solution: A white card feeding device includes two opposing outer walls, with a belt conveyor structure driven by a motor between the outer walls. A pair of drive shafts are also provided between the outer walls, located above and below the white card respectively. One of the drive shafts is connected to the motor and has a drive wheel. A crossbar is provided between the outer walls, and a cylinder is mounted on the crossbar. The output end of the cylinder is connected to a pressure bar, which extends toward the belt conveyor structure and forms a gap with the belt surface that allows only a single white card to pass through.

[0004] Preferably, the outer wall is also provided with a side baffle, which together with the pressure strip forms a limiting card compartment for storing white card stacks.

[0005] Preferably, a rotating rod is provided at the discharge port on the outer wall, and a rotating block is rotatably provided on the rotating rod. An adjustable pressure rod is connected to the rotating block by bolts, and a guide wheel is provided at the end of the pressure rod.

[0006] Preferably, the pressure bar can slide along the rotating block and be fixed by bolts, thereby adapting to white card stacks of different heights.

[0007] Preferably, the guide strip has an inclined bevel to guide the white card smoothly into the channel.

[0008] Preferably, the drive wheel is positioned on the discharge side of the gap to assist in pushing the separated individual white cards.

[0009] Preferably, a guide strip is provided at the feed inlet on the outer wall, and a pair of side baffles are provided on the guide strip, forming a channel for the white card to enter between the two side baffles.

[0010] This utility model provides a white card feeding device. It has the following beneficial effects: By combining a motor-driven belt conveyor structure with a drive wheel and an automatic separation mechanism, the automatic feeding and single-sheet separation of white cards is achieved, completely replacing traditional manual operations and greatly improving production efficiency.

[0011] The unique pressure strip design, with a precise gap between it and the conveyor belt surface, effectively blocks the upper white cards, ensuring that only the bottom white card is allowed to pass through at a time. This achieves stable and reliable single-card separation and avoids double-card or jamming. Attached Figure Description

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, what is described is only a part of this utility model, not all of it. Based on this utility model, all other inventions obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0015] See attached document Figure 1-4 A white card feeding device includes two corresponding outer walls 1 forming an inlet and a feed outlet, a pair of rollers disposed between the outer walls 1, and a belt sleeved on the rollers. The belt conveyor structure is driven by a motor 11 connected to the outer walls 1 to rotate the rollers. This structure belongs to the prior art and is only briefly described. A guide bar 12 is provided at the feed inlet of the outer wall 1. The guide bar 12 has an inclined bevel to facilitate the introduction of white cards. A pair of side stops 13 are also connected to the guide bar 12, and a channel for the white cards to enter is left between the side stops 13.

[0016] A pair of drive shafts 14 are connected between the outer walls 1, located above and below the channel respectively. One end of one drive shaft 14 is connected to the motor 11 for transmission. A drive wheel 15 is also connected to the drive shaft 14. When the white card enters and passes through, the drive wheel 15 rotates and drives the white card into the channel.

[0017] A crossbar 2 is connected between the outer walls 1. The crossbar 2 is arranged in a cross direction with the outer wall 1. A cylinder 21 is connected to the top of the crossbar 2. The cylinder 21 is perpendicular to the conveying direction of the outer wall 1. The output end of the cylinder 21 is also connected to a pressure bar 22. A side baffle (not shown in the figure) is also connected to the outer wall 1. The side baffle and the pressure bar 22 form a limiting card compartment that can store stacked white cards. The pressure bar 22 extends towards the conveyor belt and leaves a gap between it and the surface of the white card. When the belt drives the white card to move, the white card slides out from the gap and is pushed by the drive wheel 15 to ensure that the white card smoothly enters the channel and is transferred to the next processing program.

[0018] A rotating rod 3 is also provided at the discharge port of the outer wall 1. A rotating block 31 is rotatably mounted on the rotating rod 3, and the rotating rod 3 is located at the lower part of the rotating block 31. A pressure rod 32 is also connected to the upper part of the rotating block 31 by bolts. The pressure rod 32 can slide along the rotating block 31 and be fastened to its required position by bolts. One end of the pressure rod 32 extends onto the conveyor belt, and a guide wheel 33 is also connected to the extended end of the pressure rod 32. The length of the pressure rod 32 can be adjusted according to the height of the stacked white cards. The guide wheel 33 abuts against the top of the white cards to facilitate the bottom white card to pass through the gap between the pressure bar 22 and the conveyor belt. Working process: A stack of white cards is placed into the card compartment formed by side baffles, pressure strips 22, and a conveyor belt. The bottom of the stack of white cards contacts the surface of the conveyor belt, while the top of the top layer of white cards contacts the guide wheel 33. By adjusting the extension length and height of the pressure bar 32 on the rotating block 31, the guide wheel 33 can always press against the top of the stack of white cards with appropriate pressure to accommodate stacks of white cards of different heights. The motor 11 is started, and the motor 11 drives the drive shaft 14 and its drive wheel 15 to rotate, while simultaneously driving the belt conveyor structure. When the belt is running, the friction between it and the bottom white card causes the white card to move outward. Because the pressure bar 22 extends downward, there is a small gap between it and the surface of the white card, allowing only the bottom white card to pass through. The pressure bar 22 plays a key role in blocking the white cards above and achieving single-card separation. The separated single white card slides out from the gap below the pressure bar 22 and slides out through the channel formed by a pair of side baffles 13 connected to the guide bar 12, entering the next processing procedure.
