Description

Technical Field

[0001] The invention relates to the technical field of paper board product equipment, and in particular to a waste removal and receiving device for paper board products. Background Art

[0002] In the traditional printing and packaging industry, the waste removal of paper and board products is a crucial process. After the trimming and forming (die-cutting) process of materials such as cardboard and corrugated paper is completed, removing the excess waste edges becomes an indispensable step. In the past, this process mainly relied on manual operation, and workers had to use their hands to tear off the waste edges of die-cut paper and board products one by one. This not only requires workers to have a high degree of concentration, but also requires a lot of physical labor. Maintaining the same action for a long time makes workers very prone to physical fatigue and the labor intensity is extremely high. Moreover, the speed of manual operation is restricted by physiological limits, and the work efficiency is very low. For example, in some small printing and packaging workshops, a skilled worker may only be able to complete the waste removal of hundreds of paper and board products a day. This is undoubtedly a drop in the bucket for large-scale production needs, which seriously affects the production progress, resulting in limited production capacity of enterprises and inability to meet market order needs in a timely manner.

[0003] With the continuous progress and development of science and technology, automation technology has gradually penetrated into all aspects of the printing and packaging industry, and the waste cleaning process has also ushered in new changes. At present, automated waste cleaning machines have appeared on the market to replace some manual waste cleaning work. This type of waste cleaning machine can crush the waste edges of paper and board products through mechanical structure and power system, and try to collect the crushed waste edges. However, there are many complexities in its process design. The waste cleaning machine often needs to be equipped with a variety of components with different functions, such as a sensor system for accurately locating the waste edge position, a crushing tool group for crushing the waste edge, and a complex control system for controlling the tool movement trajectory. These components work together and need to be finely debugged and matched to ensure the normal operation of the waste cleaning machine. Once a component fails or the parameters are improperly set, it may lead to poor waste cleaning effect or even the machine cannot work properly. The maintenance and debugging process is time-consuming and labor-intensive, increasing the company's production costs and downtime.

[0004] What is even more thorny is that the problem of collecting the scrap edges after being shredded by the waste stripping machine has not been properly solved. The shredded scrap edges are in the form of irregular small pieces, are thin and light in texture, and are numerous, making them easy to scatter everywhere. During the collection process, special collection devices are required, such as dust collection systems, conveyor belts, etc. However, even so, it is still difficult to avoid some scrap edges from escaping into the working environment during the collection process, which not only causes environmental pollution in the working area and increases cleaning costs, but may also cause scrap edges to mix into finished paper and board products, affecting product quality. In addition, the existing collection devices are not satisfactory in terms of collection efficiency, and it is difficult to match the shredding speed of the waste stripping machine, resulting in the accumulation of scrap edges, which further affects the continuous operation of the waste stripping machine and reduces overall production efficiency.

[0005] Therefore, there is an urgent need to provide an improved technical solution to solve the above technical problems. Summary of the invention

[0069] Embodiment 3:

[0070] This embodiment provides a waste removing and receiving device for paper board products. In addition to including the technical solutions of the above embodiments, it also has the following technical features.

[0071] The lifting mechanism 23 includes:

[0072] The first driving motor 241 is fixedly arranged on the mounting bracket;

[0073] The lifting drive shaft rod 242 is rotatably connected to the mounting bracket, and the first driving motor 241 drives the lifting drive shaft rod 242 to rotate through a gear set. Sprockets 243 are arranged on the outer surfaces at both ends of the lifting drive shaft rod 242;

[0074] The chain 244, one end of the chain 244 is fixedly connected to one end of the receiving platform 21 opposite to the sliding bases 22, the other end is engaged with the sprockets 243, and a limiting plate 245 is arranged on one side of the sprockets 243, and the limiting plate 245 abuts against one side of the chain 244.

[0075] The specific structure of the lifting mechanism 23 includes a first drive motor 241, a lifting drive shaft 242, a chain 244 and a gear set. The first drive motor 241 is fixed on the mounting bracket. The output shaft of the first drive motor 241 runs through the mounting bracket. A first transmission wheel of the gear set is fixed on the output shaft. A second transmission wheel of the gear set is fixed on the outer periphery of the lifting drive shaft 242. The first transmission wheel cooperates with the second transmission wheel. Both ends of the lifting drive shaft 242 are rotatably connected to both sides of the mounting bracket through bearings. Sprockets 243 are fixed on the outer surfaces of both ends of the lifting drive shaft 242. A limit plate 244 is provided on the outer side of the circumference of the sprocket 243. 5. A space for accommodating the chain 244 is formed between the limiting plate 245 and the sprocket 243. When the chain 244 is engaged with the sprocket 243, one side of the chain 244 is engaged with the sprocket 243, and the other side of the chain 244 abuts against the limiting plate 245. The limiting plate 245 can prevent the chain 244 from detaching from the sprocket 243, and the limiting plate 245 can abut against the roller of the chain 244. Since the roller can roll, the wear of the chain 244 on the limiting plate 245 can be reduced. In addition, a conveying surface composed of a conveyor belt can be added to the limiting plate 245. The conveying surface abuts against the chain 244, which can also reduce wear and extend the service life.

[0076] The other end of the chain 244 is fixed to the end of the receiving platform 21 opposite to the sliding base 22 .

[0077] It should be noted that two chains 244 are provided, which can increase the stability of the lifting mechanism 23 in lifting the receiving platform 21 .

[0078] Embodiment 4:

[0079] This embodiment provides a waste disposal and receiving device for paper board products, which, in addition to the technical solutions of the above-mentioned embodiments, also has the following technical features.

[0080] The lifting device 13 comprises:

[0081] The rotating shaft 131 has two ends rotatably connected to the mounting bracket, and the rotating shaft 131 is fixed with an eccentric wheel disc 132;

[0082] An eccentric collar 133 is rotatably and slidably arranged outside the eccentric wheel disc 132. A connecting hinge 134 is fixedly connected to the outer wall of the eccentric collar 133. The lower end of the connecting hinge 134 is swingably connected to the male mold or the female mold.

[0083] The lifting drive device 135 is used to drive the rotating shaft 131 to rotate.

[0084] The lifting device 13 includes a rotating shaft rod 131 and an eccentric collar 133. On the outer surface of the rotating shaft rod 131, two eccentric disc wheels 132 that are symmetric in the radial direction of the rotating shaft rod 131 are fixedly provided. The eccentric disc wheels 132 can be integrally formed with the rotating shaft rod 131. The eccentric collar 133 is sleeved on the eccentric disc wheels 132. The cross-section of the eccentric collar 133 is U-shaped. And for facilitating the installation of the eccentric disc wheels 132 into the eccentric collar 133, one end face of the eccentric collar 133 is detachable. A bearing is provided between the eccentric collar 133 and the eccentric disc wheels 132 to reduce wear and unnecessary energy consumption. The inner side walls of the two end faces of the eccentric collar 133 abut against the two end faces of the eccentric disc wheels 132, and a number of circumferentially evenly distributed balls for reducing friction can be added on the eccentric disc wheels 132.

[0085] One end of the connecting hinge rod is fixedly welded to the lower end of the eccentric collar 133, and reinforcing rib plates are provided on both sides of the connecting hinge rod in the radial direction of the eccentric collar 133. The other end of the connecting hinge rod 134 is swingably connected to a slide seat for moving the male mold up and down.

[0086] The lifting drive device 135 is a motor, which is connected to the rotating shaft rod 131 through a coupling to drive the rotating shaft rod 131 to rotate. When the rotating shaft rod 131 rotates, it drives the eccentric disc wheels 132 to rotate. The eccentric disc wheels 132 can drive the eccentric collar 133 to rotate around the rotating shaft rod 131, and the connecting hinge rod 134 swings downward as the eccentric collar 133 rotates. Since the lower end of the connecting hinge rod 134 can only move along the sliding direction of the slide seat, the slide seat and the male mold fixedly connected to the slide seat can be controlled to move up and down. Since the edge of the paper product is relatively fragile, when a quick-insert and quick-remove air cylinder is used to drive the male mold to move up and down, the edge of the paper product finished product will be uneven, resulting in a reduction in the quality of the finished product. Therefore, when the male mold rod abuts against the paper sheet, the feeding speed should be slow first and then fast, slowly disconnecting all the connection points at the edge of the finished product, which can improve the quality of the finished product. With the cooperation of the eccentric collar 133 and the eccentric disc wheels 132, the movement trajectory is circular. Therefore, on a straight line, the up and down movement speed is in the form of slow-fast-slow, which can well improve the quality of the finished product.

[0087] In addition, two rotating shaft rods 131 and the corresponding eccentric collars 133 can be provided, and the lifting drive device 135 can be used to drive the two rotating shaft rods 131 to rotate synchronously through a sprocket 243 and a chain 244. The specific structure can be but is not limited to: two sprockets 243 are axially provided on the output shaft of the lifting drive device 135, and one sprocket 243 is provided on each rotating shaft rod 131, and the lifting drive device 135 can drive the two rotating shaft rods 131 to rotate through two chains 244.

[0089] The sliding base 22 includes:

[0090] A first body 221, which is fixedly arranged on the receiving platform 21;

[0091] Climbing rollers 222, at least four climbing rollers 222 are provided, and they are clamped in pairs on the climbing rod 3.

[0092] The mounting bracket includes two symmetrically arranged climbing rods 3. The climbing rod 3 includes but is not limited to a rod-shaped structure with a square cross-section. The sliding base 22 includes a first body 221 and climbing rollers 222. The first body 221 is in a plate-like structure, and four climbing rollers 222 are provided on the side of the first plate body close to the climbing rod 3, two on each side of the climbing rod 3, and the climbing rollers 222 are pressed against the climbing rod 3, and a rubber layer is wrapped on the surface of the climbing rollers 222 to increase the friction force.

[0093] The receiving platform 21 further includes a first slope 211 and a positioning baffle 212.

[0094] When the receiving platform 21 descends to the ground, since the receiving tray filled with finished products is large and heavy, a single person needs to move the receiving tray out by a manual forklift. With the setting of the first slope 211, it can make the rollers of the forklift more convenient to get onto the platform. The set positioning baffle 212 is to make the receiving position of the receiving tray more accurate.

[0095] It further includes:

[0096] A guiding receiving tray 4, the guiding receiving tray 4 includes a guiding slope and a discharge port, the guiding receiving tray 4 is installed under the waste-removing female mold 12 and receives the formed product.

[0097] The top opening of the guiding receiving tray 4 presents a flared shape, including a guiding slope and a discharge port. The finished product falls onto the guiding slope and falls from the discharge port to the middle position of the receiving tray, making the discharge position of the finished product more concentrated and not easily falling outside the receiving tray.

[0098] The waste-removing device 1 further includes:

[0099] A first mounting frame 14, which is slidably arranged on both sides of the mounting bracket and is provided with a first supporting groove 141, and both sides of the waste-removing male mold 11 are inserted into the first supporting groove 141;

[0100] A female mold supporting rod 15, both ends of the female mold supporting rod 15 are fixedly arranged on the mounting bracket, and first limiting parts 151 are arranged on the female mold supporting rod 15 on both sides of the waste-removing female mold 12.

[0101] That is, the waste removing male mold 11 is slidably connected to the mounting bracket through the first mounting frame 14. The waste removing male mold 11 is slidably and detachably mounted in the first supporting groove 141 of the first mounting frame 14. The opening direction of the first supporting groove 141 is perpendicular to the sliding direction of the first mounting frame 14, and the position can be fixed by passing a fastener through the waste removing male mold 11 and the first mounting frame 14. Below the waste removing male mold 11, there are two female mold supporting rods 15 for mounting the female mold. On the left and right sides of the mounted female mold, there are first limiting parts 151 fixedly connected to the female mold supporting rods 15. The gap formed by the two first limiting parts 151 is equal to the width of the waste removing female mold 12. The positioning of the waste removing female mold 12 is more accurate through the first limiting parts 151, and the position can be fixed by passing a fastener through the female mold supporting rods 15 and the waste removing female mold 12.

[0102] The other end of the chain 244 connected to the receiving platform 21 is provided with a counterweight part 5.

[0103] The provided counterweight part 5 can help the receiving platform 21 to be lifted faster.

[0104] The weight of the counterweight part 5 should be similar to or equal to the weight of the receiving platform 21. On the chain 244, the sprocket 243 is located between the counterweight part 5 and the end of the chain 244 connecting to the receiving platform 21. The tension at both ends of the chain 244 is balanced by the counterweight part 5, so that the tension is balanced and the force output by the sprocket 243 to move the chain 244 is reduced.

[0105] The chain 244 includes a vertical part and a horizontal part. The vertical part is connected to the receiving platform 21, and the horizontal part is connected to the sprocket 243. On the mounting bracket, there is a guide wheel 6 for turning the chain 244.

[0106] By dividing the chain 244 into a horizontal part and a vertical part, the chain 244 can be turned by the guide wheel 6 at the bending part. Through the setting of the horizontal part, part of the gravity of the chain 244 can be applied to the sprocket 243 along the radial direction of the sprocket 243, which can increase the structural stability. And the distance between the setting position of the sprocket 243 and the connection position of the chain 244 and the receiving platform 21 can be made larger, so that the installation space is larger, and the position of the guide wheel 6 can be adjusted to adapt to receiving platforms 21 of more sizes.
