[0014] Among them: frame 10, pulp roll 12, metal detector 14, linear module 16, metal removal mechanism 18, moving box 20, cylinder 22, cutting knife 24, waste box 26, arc edge 28. Detailed Embodiments

[0015] The technical solutions of this patent will be further described in detail below in conjunction with the specific embodiments.

[0016] As Figure 1 and Figure 2 shown, a metal removal device for pulp rolls of the present utility model includes a frame 10. A pulp roll 12 and a pulverizer for pulverizing the pulp roll 12 are provided on the frame 10. A plurality of groups of roller shafts are provided on the frame 10. The pulp roll 12 is laid flat on the roller shafts and is changed in direction and conveyed to the inlet of the pulverizer through the roller shafts. A metal detector 14 for detecting the pulp roll 12 and a metal removal mechanism 18 for cutting the pulp roll 12 are provided on the frame 10. The metal removal mechanism 18 can move along the conveying direction of the pulp roll 12. The metal detector 14 has a plurality of detection areas in the width direction of the pulp roll 12, and there is an overlapping part between two adjacent detection areas. The metal removal mechanism 18 includes a plurality of cutting components corresponding to the detection areas;

[0017] The metal detector 14 is used to detect whether there is metal in the pulp roll 12. The cutting assembly is used to cut the pulp roll 12 containing metal. After it is detected that there is metal in the pulp roll 12, the metal removal mechanism 18 starts to move along the conveying direction of the pulp roll 12 and keeps the same speed as the pulp roll 12, so that the metal cutting mechanism and the pulp roll 12 remain relatively stationary, which is convenient for cutting. A plurality of detection areas correspond to the cutting assemblies one by one, making the detection results more accurate. The cutting can also cut off a smaller pulp roll 12 on the premise of removing the metal. The shape and size of the detection area are the same as those of the cutting area of the cutting assembly. Since the cutting part of the cutting assembly has a certain thickness, this part is not easy to be cut off during the cutting process, and this situation is avoided by setting an overlapping part.

[0018] A guide rail is arranged on the frame 10. The metal removal mechanism 18 includes a moving box 20 slidably arranged on the guide rail. A linear module 16 for driving the moving box 20 to move is arranged on the frame 10. An opening for the pulp roll 12 to pass through is formed on the moving box 20. The cutting assembly is arranged on the moving box 20 and above the pulp roll 12. A waste box 26 located below the pulp roll 12 is arranged in the moving box 20;

[0019] The length directions of the guide rail and the linear module 16 are the same as the conveying direction of the pulp roll 12. The guide rail is used to support the moving box 20 and reduce the friction force. The linear module 16 has a stable moving speed and high accuracy. The waste generated by cutting is received by the waste box 26 below, which is convenient for cleaning.

[0020] A plurality of cutting assemblies are arranged in the moving box 20 along the width direction of the pulp roll 12, and adjacent cutting assemblies are staggered in the conveying direction of the pulp roll 12;

[0021] The detection area has an overlapping part. The shape and size of the cutting area are the same as those of the detection area. If the cutting assemblies are on the same straight line, mutual interference will occur. The interference is avoided by setting two columns of cutting assemblies and staggering the two columns of cutting assemblies.

[0022] A plurality of metal removal mechanisms 18 are slidably arranged on the guide rail, and the plurality of metal removal mechanisms 18 are individually driven by different linear modules 16 to slide on the guide rail;

[0023] The metal removal mechanism 18 will move in the conveying direction of the pulp roll 12 during the cutting process, and then reset for the next cutting after the cutting is completed. If there is metal in two areas close to each other in the length direction of the pulp roll 12, a single metal removal mechanism 18 cannot continue to cut the next area after the first cutting. This problem is solved by setting at least two metal removal mechanisms 18. When there are continuously areas that need to be cut off, the first metal removal mechanism 18 resets after cutting the first area, and the second area is cut by the second metal removal mechanism 18.

[0024] The cutting component includes several cylinders 22 arranged in the moving box 20, and the bottom of each of the several cylinders 22 is provided with a cutting knife 24 for cutting the pulp roll 12;

[0025] The expansion and contraction of the cylinder 22 drives the lifting of the cutting knife 24 to cut the pulp roll 12. The cutting knives 24 enclose a closed figure to prevent the waste material from adhering to the pulp roll 12 during the cutting process.

[0026] The top of the waste box 26 is provided with an arc edge 28 corresponding to the cutting knife 24, and the top of the arc edge 28 is in contact with the pulp roll 12;

[0027] The arc edge 28 is used to support the pulp roll 12, facilitating cutting, and also plays a certain guiding role for the cutting knife 24.

[0028] The content protected by the present utility model is the physical structure of the above device. The driving, control, feedback, etc. between each component are all program-controlled, and this program control is well-known to those skilled in the art and is not the content protected by the present utility model.
