Description

Technical Field

[0001] This utility model belongs to the field of cardboard box processing technology, specifically relating to an anti-clogging feeding device for a cardboard box die-cutting machine. Background Technology

[0002] The carton die-cutting machine is the core equipment in the carton production process to achieve precise forming and processing of cardboard. It is mainly used to complete key processes such as die-cutting, creasing, and waste removal of roll paper or single cardboard according to the preset carton unfolding pattern. The anti-blocking feeding device of the carton die-cutting machine is a device used to prevent feeding blockage during the carton die-cutting process. It ensures that the cardboard can enter the die-cutting machine smoothly and accurately for processing through various methods.

[0003] For example, in the Chinese utility model publication CN214137521U entitled "Feeding Device for a Carton Die-cutting Machine," the device specifically includes an equipment compartment with an inclined track inside. The end of the track is positioned directly above a conveyor belt. A baffle is provided at the upper end of the track. Several sets of rotating wheels are arranged along the track below the baffle. The rotating wheels rotate at different speeds, and the distance between the rotating wheels and the track is less than the thickness of the cardboard. The aforementioned prior art feeding device with this structure is simple and cost-effective. However, the cardboard may stack on the feeding device, making it inconvenient to lay the cartons flat on the feeding device and avoid stacking. Therefore, there is a need for an anti-clogging feeding device for a carton die-cutting machine. Utility Model Content

[0004] The purpose of this utility model is to provide a simple and reasonably designed anti-clogging feeding device for a carton die-cutting machine in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions: A carton die-cutting machine anti-clogging feeding device includes an operating table. A protective shell is fixedly installed on the upper side of the operating table. A photoelectric sensor is fixedly installed inside the protective shell. A fixing plate is installed on the upper side of the operating table. An electric telescopic rod is fixedly installed on the upper side of the fixing plate. A baffle is fixedly installed at the output end of the electric telescopic rod. Limiting mechanisms are provided at both ends of the upper side of the operating table.

[0006] As a further optimization of this utility model, limit rods are fixedly provided at both ends of the upper side of the baffle, and through holes are provided at both ends of the fixed plate, with the limit rods slidingly disposed in the through holes.

[0007] As a further optimization of this utility model, a first servo motor is fixedly installed on one side of the operating table, and a conveyor belt is fixedly installed at the output end of the first servo motor. The conveyor belt is installed in a groove opened on the upper side of the operating table.

[0008] As a further optimization of this utility model, a mounting bracket is fixedly provided on the upper middle part of the operating table, and a first groove is provided on one side of the mounting bracket.

[0009] As a further optimization of this utility model, the limiting mechanism includes a second servo motor, which is fixedly mounted on one side of the mounting frame. The output shaft of the second servo motor is fixedly mounted with a bidirectional screw, which is rotatably mounted in a first groove. Both sides of the bidirectional screw are threaded with connecting rods. A V-shaped guide plate is fixedly mounted on the lower side of the connecting rod. A top plate is fixedly mounted on the upper end of one side of the V-shaped guide plate. Several rubber pressure rollers are rotatably mounted on the lower side of the top plate.

[0010] As a further optimization of this utility model, a second groove is provided on one side of the operating table, and a cleaning roller is fixedly installed in the second groove by bolts, with the upper side of the cleaning roller in contact with the lower side of the conveyor belt.

[0011] The beneficial effects of this utility model are as follows: By setting up a photoelectric sensor and a baffle, this utility model can prevent cardboard from stacking and causing die-cutting blockage. The photoelectric sensor is fixedly set on the rear left side of the top surface of the operating table. The baffle is driven to move up and down by an electric telescopic rod. The upper two ends of the baffle are limited to the fixed plate by limit rods to restrict the movement direction of the baffle. The photoelectric sensor and the baffle work together to push the stacked cardboard apart and prevent cardboard from stacking. By setting up a V-shaped guide plate and a rubber pressure roller, it can prevent the cardboard from deviating during feeding. V-shaped guide plates are set at both the front and rear ends of the upper side of the conveyor belt. The upper side of the V-shaped guide plate is connected to the bidirectional screw on the mounting frame through a connecting rod. The output shaft of the second servo motor drives the bidirectional screw to rotate, so that the V-shaped guide plates on both sides can move in opposite directions at the same time to limit the cardboard. A rotatable rubber pressure roller is set on the inner side of the V-shaped guide plate to ensure normal cardboard conveying. Attached Figure Description

[0014] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content. Example

[0015] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a cardboard die-cutting machine anti-clogging feeding device includes an operating table 1. A first servo motor 2 is fixedly installed on one side of the operating table 1. A conveyor belt 3 is fixedly installed at the output end of the first servo motor 2. The conveyor belt 3 is set in a groove opened on the upper side of the operating table 1. Cardboard is placed on one end of the upper side of the conveyor belt 3. When the first servo motor 2 is turned on, the output shaft of the first servo motor 2 drives the conveyor belt 3 to rotate, so that the cardboard on the conveyor belt 3 moves from one end to the other end, feeding it into the die-cutting machine.

[0016] like Figure 1 , Figure 2 , Figure 4 , Figure 5As shown, a protective shell 4 is fixedly installed on the upper side of the operating platform 1. The protective shell 4 is an inverted C-shaped protective component. A photoelectric sensor 5 is fixedly installed inside the protective shell 4. The protective shell 4 and the photoelectric sensor 5 are located on the side where the cardboard begins to be conveyed, and sense the stacked cardboard. A mounting frame 6 is fixedly installed in the middle of the upper side of the operating platform 1. A fixing plate 7 is fixedly installed on one side of the mounting frame 6. An electric telescopic rod 8 is fixedly installed on the upper side of the fixing plate 7. A baffle 9 is fixedly installed at the output end of the electric telescopic rod 8. The baffle 9 is located on the lower side of the fixing plate 7. Limit rods 10 are fixedly installed at both ends of the upper side of the baffle 9. Through holes 11 are opened at both ends of the fixing plate 7, and the limit rods 10 slide through them. The output end of the electric telescopic rod 8, installed inside the through hole 11, drives the baffle 9 to move up and down. When the baffle 9 moves up and down, the limiting rod 10 slides inside the through hole 11, limiting the direction of movement of the baffle 9 and preventing the angle of the baffle 9 from changing. When the photoelectric sensor 5 senses that there is a stack of cardboard, it activates the electric telescopic rod 8. The electric telescopic rod 8 moves the baffle 9 downward until the bottom surface of the baffle 9 is above the bottom cardboard, blocking all cardboard except the bottom one. The bottom cardboard continues to be carried by the conveyor belt 3 until the stacked cardboard falls onto the conveyor belt 3. The above structure can lay the cardboard flat and prevent stacking from causing blockage in front of the die-cutting machine.

[0017] like Figure 2 , Figure 3 , Figure 4As shown, a first groove 12 is provided on one side of the mounting frame 6. Limiting mechanisms 13 are provided at both ends of the upper side of the operating table 1. The limiting mechanism 13 includes a second servo motor 1301. The second servo motor 1301 is fixedly installed on one side of the mounting frame 6. A bidirectional screw 1302 is fixedly installed on the output shaft of the second servo motor 1301. The bidirectional screw 1302 is rotatably installed in the first groove 12. Connecting rods 1303 are threaded on both sides of the bidirectional screw 1302. A V-shaped guide plate 1304 is fixedly installed on the lower side of the connecting rod 1303. The bottom side of the V-shaped guide plate 1304 is in contact with the upper side of the conveyor belt 3. A top plate 1305 is fixedly installed on the upper end of one side of the V-shaped guide plate 1304. Several rubber pressure rollers 1306 are rotatably installed on the lower side of the top plate 1305. The bottom side of the rubber pressure rollers 1306 is in contact with the upper side of the conveyor belt 3. According to the width of the cardboard, the spacing between the V-shaped guide plates 1304 is adjusted, and the second servo motor 1301 is started. The output shaft of the second servo motor 1301 drives the bidirectional screw 1302 to rotate, so that the V-shaped guide plates 1304 on both sides move in opposite directions at the same time. The V-shaped guide plates 1304 move inward at the same time according to the width of the cardboard until the shortest spacing between the V-shaped guide plates 1304 on both sides is close to the width of the cardboard. Since the cardboard is still conveyed by the conveyor belt 3 while the V-shaped guide plates 1304 restrict the width of the cardboard, a rubber pressure roller 1306 is set on the inner side of the V-shaped guide plate 1304. The outer side of the cardboard is in contact with the inner side of the rubber pressure roller 1306. The rubber pressure roller 1306 can rotate, which does not affect the cardboard's continued conveying by the conveyor belt 3 while its movement position is restricted, thus preventing the cardboard's position from shifting.

[0018] like Figure 3 As shown, a second groove 14 is provided on one side of the operating table 1. The second groove 14 is located on the side close to the die-cutting machine. A cleaning roller 15 is fixed to the bottom of the inner side of the second groove 14 by bolts. The upper side of the cleaning roller 15 is in contact with the lower side of the conveyor belt 3. When the cardboard is conveyed, the rough edges of the cardboard will fall onto the conveyor belt 3, and the surface of the conveyor belt 3 needs to be cleaned. The cleaning roller 15 is provided so that when the belt on the conveyor belt 3 moves, the cleaning roller 15 wipes away the debris on the surface of the belt on the conveyor belt 3.

[0019] It should be noted that this anti-clogging feeding device for a carton die-cutting machine involves placing the carton on one side of the conveyor belt 3, starting the first servo motor 2, which drives the conveyor belt 3 to convey the cardboard. When the photoelectric sensor 5 detects stacked cardboard, the electric telescopic rod 8 is activated. The output end of the electric telescopic rod 8 moves downward with the baffle 9, spreading the stacked cardboard flat and preventing blockage caused by cardboard stacking. The cardboard continues to move towards the die-cutting machine. When the cardboard reaches the middle of the conveyor belt 3, the second servo motor 1301 is activated. The output end of the second servo motor 1301 drives the bidirectional screw 1302 to rotate, causing the V-shaped guide plates 1304 on both sides to move inward with the rubber pressure rollers 1306 until the inner side of the rubber pressure rollers 1306 is in contact with the two sides of the cardboard, restricting the direction of movement of the cardboard and preventing the cardboard from deviating from its feeding position towards the die-cutting machine. As the belt on the conveyor belt 3 moves on the rollers on both sides, the cleaning roller 15 cleans the debris attached to the surface of the belt on the conveyor belt 3.

[0020] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
