[0002] In the processing of materials with continuous carriers, a coating or pattern of a certain area is formed on the material by printing, coating, etc., and the coating or pattern is not continuous, such as Figure 5 As shown, a sheet area 100A with a coating or pattern and a waste material 100B without a coating or pattern located between a pair of sheet areas 100A are formed on a continuous material 100. The sheet area 100A and the waste material 100B are connected in sequence at intervals, but the required material is only the cut sheet area 100A.

[0003] In the prior art, the waste 100B and the sheet area 100A can be cut and collected in sequence by manual and mechanical methods, but the operation accuracy is poor and the operation efficiency is low; for example, in a cutting and recovery device with application number 201721007442.4, and an automatic material dividing and die-cutting machine with application number 202121317255.2, the disclosed devices are all for cutting off the waste at the side of the continuous material, rather than the waste 100B in the above-mentioned form. Therefore, a new unloading device is needed to realize the above-mentioned cutting of the sheet area 100A and the waste 100B connected in sequence (to realize the cutting of the sheet area 100A and the waste 100B, and to realize the independent collection of the two). Utility Model Content

[0004] The purpose of the utility model is to provide a waste material cutting and unloading device, which can realize the automated processing of sheet materials by cutting off the waste materials of the material and unloading the sheet materials after forming them through the cooperation of the cutting mechanism and the collecting mechanism, and the unloading sheet materials and the cut waste materials can be unloaded separately, and the unloading processes between the two will not affect each other, which is helpful for the subsequent material collection.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a waste cutting and unloading device, comprising a bottom plate, and:

[0016] As a further optimization, a blowing hole is provided on the side wall of the base close to the top plate. When the waste is narrow and difficult to be pushed forward and fed into the gap, the waste can be blown into the gap by blowing.

[0025] The following are specific embodiments of the utility model in combination with the drawings, and the technical solutions of the utility model will be further described, but the utility model is not limited to these embodiments.

[0026] Such as Figures 1 to 2 Combined with Figure 5As shown, a waste material cutting and unloading device includes a base plate 1, a feeding table, a feeding mechanism 3, a cutting mechanism 4 and a receiving mechanism 5. The feeding table includes a first feeding table 21 located at the front side of the base plate 1, and a second feeding table 22 located at the rear side of the base plate 1. The first feeding table 21 and the second feeding table 22 are used to transport materials, and there is a clearance gap 20 between the two. More specifically, the first feeding table 21 carries a continuous material 100 for feeding, and the second feeding table 22 carries a sheet 100A after the waste 100B is cut. The feeding mechanism 3 is arranged on the base plate 1 and is located in the clearance gap 20. It has a transmission power for transporting the material 100. The cutting mechanism 4 is arranged in the clearance gap 20 and is located beside the feeding mechanism 3 for cutting the material 100. The purpose of the cutting mechanism 4 is to cut the waste 100B on the material 100 and only retain the sheet 100A. The collecting mechanism 5 includes a supporting cylinder 51 and a top plate 52. A pair of supporting cylinders 51 are arranged on the bottom plate 1, and the top plate 52 is arranged at the output end of the supporting cylinder 51 and is located beside the cutting mechanism 4 away from the feeding mechanism 3. When the top plate 52 is driven to be flush with the second feeding table 22, it carries the material for feeding (at this time, it carries the feeding sheet 100A), or the top plate 52 is driven to move upward to form a gap 50 for collecting the cut waste 100B.

[0027] In the present utility model, the material 100 is loaded from one side of the first feeding table 21. The material 100 can be pulled by the feeding mechanism 3 and is fed while being carried on the first feeding table 21. When the material 100 passes through the feeding mechanism 3, such as when it is in the area of the sheet material 100A, continuous feeding is carried out and the cutting mechanism 4 does not operate. After the area of the sheet material 100A completely passes through the cutting mechanism 4 and when the connection position between the sheet material 100A and the waste material 100B is within the cutting mechanism 4, the cutting mechanism 4 works, so that the sheet material 100A passing through the cutting mechanism 4 is separated from the waste material 100B on the material 100. The sheet material 100A is in a sheet shape and is located on the top plate 52 and the second feeding table 22, or is transferred by an operator or a manipulator, or is discharged by a feeding line connected to the second feeding table 22. At the same time, the material with the waste material 100B continues to be fed. When the connection position between the waste material 100B and the next section of the sheet material 100A is within the cutting mechanism 4, the cutting mechanism 4 works, so that the waste material 100B passing through the cutting mechanism 4 is separated from the sheet material 100A on the material 100. To avoid confusion caused by the simultaneous feeding of the waste material 100B and the sheet material 100A on the second feeding table 22, after the waste material 100B is separated from the material 100, the support cylinder 51 drives the top plate 52 to move upward, so that a gap 50 is formed in the front side of the second feeding table 22. The waste material 100B can enter the gap 50 to avoid being located on the second feeding table 22. Therefore, on the basis of being able to automatically slice and form the sheet material 100A of the material 100 and remove the waste material 100B, the separate discharging of the sheet material 100A and the waste material 100B can also be realized, avoiding the mixing of the two from affecting the discharging and receiving efficiency.

[0028] The present utility model can cut the waste material 100B on the continuously fed material 100 and discharge the sheet material 100A, can realize an automated processing process, and the discharged sheet material 100A and the cut waste material 100B are discharged separately and will not affect each other, which is beneficial to improving work efficiency.

[0029] Continue as Figure 2 shown, the feeding mechanism 3 includes a mounting bracket 31, a feeding roller 32, a motor 33 and a pressing component 34. The mounting bracket 31 is arranged on the bottom plate 1. The feeding roller 32 is rotatably arranged on the mounting bracket 34 and is connected to the output end of the motor 33. The pressing component 34 is arranged at the upper end of the mounting bracket 31 and abuts against the feeding roller 32. The motor 33 drives the feeding roller 32 to rotate, and the material 100 is located between the feeding roller 32 and the pressing component 34 and is fed by means of the frictional force during the extrusion process.

[0030] Furthermore, the pressing assembly 34 includes an adjusting shaft 341 and a plurality of adjusting pressure plates 342. The adjusting shaft 341 is arranged at the upper end of the mounting bracket 31. The plurality of adjusting pressure plates 342 are fixed on the adjusting shaft 341 and abut against the feed roller 32. The adjusting shaft 341 can be rotated to adjust its position relative to the feed roller 32 to ensure that the adjusting pressure plate 342 abuts against the feed roller 32. The adjusting pressure plate 342 can also adjust its horizontal position on the adjusting shaft 341 to achieve compact feeding of materials 100 of different widths.

[0031] like Figure 3 As shown, the cutting mechanism 41 includes a lifting cylinder 41, a gantry bracket 42 and a cutting knife 43. The lifting cylinder 41 is arranged on the base plate 1, the gantry bracket 42 is arranged at the output end of the lifting cylinder 41, and the cutting knife 43 is arranged on the gantry bracket 42, which can be suitable for cutting materials 100 of different widths.

[0032] Furthermore, the working surface of the cutter 43 is set at an angle, so that the material 100 can be cut sequentially from one side to the other side, similar to the process of scissors, rather than directly cutting the entire width of the material 100 at the same time, which can ensure smooth cutting.

[0033] In addition, the cutting mechanism 4 also includes a base 44, which is provided with a clearance groove 441 for the working surface of the cutter 43 to extend into, so that the cutter 43 can cut the material 100 while avoiding the base 44 and the cutter 43 from interacting with each other and causing damage to both.

[0034] In another embodiment, the base 44 is provided with adsorption holes 442 in a matrix shape on the front side of the clearance groove 441 for adsorbing the material 100. The material 100 can be fixed by the adsorption holes 442 when the cutter 43 is cutting, thereby ensuring the stability of the material 100 during cutting and the accuracy of the cutting by the cutter 43. Of course, adsorption holes can also be provided on the other side of the base 44.

[0035] Moreover, a blowing hole 443 can be provided on the side wall of the base 44 close to the top plate 52. The function of the blowing hole 443 is to blow the cut smaller (or narrower) sheet or strip waste 100B away from the base 44 and into the gap 50, so as to prevent the waste 100B from being in a smaller state and unable to smoothly detach from the base 44.

[0036] like Figure 4As shown, based on the setting with the blowing holes 443, the top plate is an inverted L-shaped structure for blocking the advancement of the cut waste 100B and causing it to fall into the gap 50. During the process of the waste 100B being blown and moving forward, the inverted L-shaped structure can be used to block the material. Additionally, a waste collection box (not shown) can be provided in the gap 20 for collecting the waste 100B that has fallen into the gap 20.

[0037] The specific embodiments described herein are merely illustrative of the spirit of the present utility model. Those skilled in the technical field to which the present utility model pertains can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.
