With the increasing demand for processing precision and efficiency in manufacturing, plate slitting machines not only need to have high efficiency, but also must meet the diversified needs in different application scenarios. For example, in many industrial production, not only the width of the plate cutting needs to meet the specific size, but also the length of the plate needs to be adjusted according to different needs to adapt to the changing processing requirements. Therefore, the development and technical improvement of plate slitting machines have always been one of the focuses of the industry. The plate slitting machine in the related art mainly includes three components: a conveying module, a slitting module, and a cutting module. Among them, the conveying module is responsible for transmitting the plate to the designated position; the slitting module cuts the plate into the required width through a pair of slitting rollers; and the cutting module further cuts the plate with the desired width to achieve the desired length. In actual application process, for the processing of conventional size plates, this technical scheme can better meet the production needs. At the same time, in order to improve production efficiency, most slitting machines also integrate automatic control systems, further improving the speed and accuracy of plate processing. However, the current plate slitting machine has a relatively obvious defect: the cutting module can only cut the plate to a fixed length. This means that when processing plates of different widths and lengths, the traditional batch operation method is not up to the task. Especially in some specific scenarios, such as customized production or small-batch multi-variety operation environment, the plate slitting machine often cannot flexibly respond to different width and length requirements, resulting in low production efficiency and difficulty in meeting customer individual needs.

[0031] The inventor of the present application finds that the plate slitting machine in the prior art includes a conveying module, a slitting module 4 and a cutting module 5, the plate 7 is first processed into a required width by the slitting module 4, and then the plate 7 is processed into a required length by the cutting module 5. However, the prior art has the following defects: the cutting module 5 can only cut the plate 7 into a required length as a whole, for example, after the slitting module 4 divides the plate 7 into two kinds of long strips with different widths, it can only cut the plate into strips with different widths and the same length, and cannot meet the case that a small amount of plates with different widths and different lengths appear in the actual processing process. Therefore, the present application mainly adopts the following scheme to achieve the processing effect of the plate 7 with different widths and different lengths, and the present application will be further described in detail below with reference to the drawings.

The overall processing process is that the plate 7 is conveyed into the machine body 1 through the guide module 2, and then sequentially passes through leveling, slitting (fixed width) and cutting (fixed length), and in the cutting process, the plate 7 needs to be back-off by cooperating with the driving module, so as to cut the plate 7 side strip and the plate 7 middle strip at different length positions.

[0033] Referring to Figure 3 The guide module 2 includes a pair of clamping rollers 21 for limiting the height position of the plate 7 and a pair of guide wheels 22 for limiting the transverse position of the plate 7, the two clamping rollers 21 are rotatably connected between the machine body 1 through bearings, the axial directions of the two clamping rollers 21 are horizontally arranged and the two clamping rollers 21 have a gap for the plate 7 to pass through between them, so as to limit the height of the plate 7 in the vertical direction, and the two guide wheels 22 are also rotatably connected with the machine body 1 through bearings, the axial direction of the guide wheel 22 is vertically placed, and the side wall of the guide wheel 22 is circumferentially provided with a ring groove for the plate 7 to embed, so as to limit the position of the plate 7 in the transverse direction.

[0034] Referring to Figure 4The flattening module 3 comprises a plurality of flattening rollers 31, each of which is rotatably connected to the side wall of the body 1 through a bearing, and the flattening rollers 31 are staggered and arranged in sequence to stably clamp the plate 7 in a flattening channel formed between the flattening rollers 31. The flattening rollers 31 are passively rotated through friction with the plate 7, so that the plate 7 can be retracted without affecting the plate 7 when the plate 7 needs to be retracted.

[0035] With reference to Figure 5 The slitting module 4 comprises a pair of slitting rollers 41, each of which is rotatably connected to the side wall of the body 1 through a bearing, and the slitting rollers 41 are provided with roller knives 42 installed on the outer sides of the slitting rollers 41 to slit the plate 7. In this embodiment, the two roller knives 42 arranged on the upper and lower sides of the slitting rollers 41 are not completely symmetrical, but are staggered, so that the plate 7 is cut through the staggered gaps between the two roller knives 42 to process a slit with a certain width. The body 1 is provided with a slitting driving member 43, which is a motor for driving the slitting rollers 41 to rotate. The slitting rollers 41 are made of high-strength steel to ensure stability and durability.

[0036] With reference to Figure 6 The cutting module 5 comprises two cutting assemblies 51, each of which is slidably connected to the body 1. Each cutting assembly 51 comprises an upper cutting die 511 and a lower cutting die 512, and the body 1 is provided with a cutting frame 52 for mounting the upper cutting die 511. The upper cutting die 511 and the lower cutting die 512 are respectively mounted through independent driving mechanisms and sliding mechanisms, so that the upper cutting die 511 can move vertically and horizontally relative to the cutting frame 52, and the lower cutting die 512 can move vertically and horizontally relative to the body 1. Since the linear driving mechanism and the sliding mechanism are prior art in the field, they will not be described in detail in this embodiment. The two independent cutting assemblies 51 can achieve accurate cutting at different positions.

[0037] With reference to Figure 7 and Figure 8In the embodiment, the conveying module is the back-off mechanism 6, which is used to control the conveying, stopping and back-off of the plate 7 to cooperate with the two cutting modules 51 to cut the two side long strips and the middle long strip of the plate 7 at independent positions. The machine body 1 is provided with a back-off frame 61, and the back-off mechanism 6 includes a pair of back-off rollers 62 made of high-strength steel. The back-off rollers 62 are connected with the bearing seat in the machine body 1 through the shaft neck, and the bearing seat provides stable support for the rotation of the back-off rollers 62. The rotation of the back-off rollers 62 is driven by the back-off driving part, which adopts a servo motor with high control accuracy and fast response speed. The servo motor can adjust the output speed and torque according to the requirements of the control system, so as to realize the accurate control of the back-off rollers 62. The servo motor can provide stable power support under high-speed operation. The transmission system between the servo motor and the back-off rollers 62 adopts a synchronous belt driving mode, and the synchronous belt is made of polyvinyl chloride material, which has high tensile strength and wear resistance, and can ensure good transmission effect under long-time operation.

[0038] With reference to Figure 7 and Figure 8 , the surface of the back-off roller 62 is sleeved with an anti-skid sleeve 64 made of rubber material. The rubber material is natural rubber, which has good elasticity, wear resistance and anti-aging performance, and can effectively enhance the gripping force between the back-off roller 62 and the plate 7. The inner side of the anti-skid sleeve 64 is integrally formed with a plurality of insertion strips 65 parallel to the axial direction, and correspondingly, the outer side of the back-off roller 62 is provided with a plurality of insertion grooves 650 for the insertion strips 65. After the anti-skid sleeve 64 is sleeved on the outer side of the back-off roller 62, it can be more stable under the cooperation of the insertion strips 65 and the insertion grooves 650, and it is not easy to rotate invalidly.

[0039] With reference to Figure 7 and Figure 8 , the specific installation mode of the two back-off rollers 62 is as follows: the two back-off rollers 62 are arranged vertically, and the lower back-off roller 62 is connected with the machine body 1 through the rotary connection with the fixed position of the back-off frame 61. The back-off frame 61 is provided with a sliding groove 660, and a sliding block 66 and a mounting seat 661 are slidably arranged in the sliding groove 660. The materials of the sliding block 66 and the mounting seat 661 are high-strength aluminum alloy, which has a low friction coefficient and a high bearing capacity. The mounting seat 661 is located above the sliding block 66, and a back-off elastic element 67 is arranged therebetween. The back-off elastic element 67 is a spring made of 65Mn steel wire, which has high elasticity and fatigue resistance.

[0040] The upper return roller 62 is rotatably connected with the slider 66 through a bearing. The return frame 61 is a door-shaped frame, and the top cross bar is detachably connected with the side vertical bars through bolts. The top of the return frame 61 is provided with an adjusting hole 680 in the vertical direction, and an adjusting rod 68 is threadedly inserted into the adjusting hole 680. The bottom of the adjusting rod 68 abuts against the mounting seat 661 to compress the return elastic member 67. By adjusting the position of the bottom of the adjusting rod 68, the compression degree of the return elastic member 67 can be adjusted, so that the clamping degree of the two return rollers 62 on the plate 7 can be adjusted.

[0041] With reference to Figure 9 The tail end of the machine body 1 is further provided with a support frame 8 for supporting the cut-off side plate 7 and / or the not-yet-cut-off middle plate 7. The support frame 8 is provided with a receiving groove 80, and a support roller frame 81 is rotatably connected in the receiving groove 80 through a bearing. The support roller frame 81 is composed of a frame body 811 and a plurality of support rollers 812 rotatably connected with the frame body 811. When the support roller frame 81 is in a horizontal state, the top of each support roller 812 extends out of the top wall of the frame body 811. The side wall of the support frame 8 is provided with a support driving member 82, which is an electric motor for driving the support roller frame 81 to rotate out of the receiving groove 80 to a horizontal state for supporting the plate 7, and can also be stored when necessary to improve the utilization rate of space. The support rollers 812 are made of stainless steel, which has good corrosion resistance and wear resistance and is suitable for supporting the plate 7 in various environments. The frame body 811 is made of high-strength aluminum alloy, which has a high weight ratio and good corrosion resistance, and can effectively ensure the stability of the entire support roller frame 81.

[0042] The rotary connection between the support roller frame 81 and the receiving groove 80 is achieved through a bearing and a pin shaft. The bearing is a precision rolling bearing, which has high load capacity and wear resistance. The end of the frame body 811 away from the rotary connection with the receiving groove 80 is rotatably provided with a support leg 83. During the opening process of the support roller frame 81, the support leg 83 can be opened synchronously with the rotation of the frame body 811. The rotation of the support leg 83 is achieved through a support leg driving member 84, which is an electric cylinder and is fixed to the support frame 8 through bolts.

[0043] The implementation principle of the embodiment is that after the plate 7 is cut into long strips of the required width by the slitting module 4, the long strips on the sides are cut off respectively by the cutting module. Further, the left and right long strips can also be cut off respectively, so as to control the different lengths of the left and right long strips. When the long strips on both sides are cut off to the middle long strip and the positions on both sides of the to-be-cut position are not blocked, the plate 7 can be controlled to return by the return mechanism 6, and then any cutting module can be used to cut the middle long strip. Thus, each long strip can be cut at different positions, so as to realize the processing of plates 7 of different widths and lengths.

[0044] The embodiment of the application further discloses a plate striping method.

[0045] Referring to Figure 10 Taking that the plate 7 is divided into the board strip A, the board strip B and the board strip C under the action of the striping module 4 as an example, the arrow direction in the figure is the conveying direction of the plate 7, the board strip A, the board strip B and the board strip C need to be processed to different lengths, the dotted lines A1, A2, B1, C1 and C2 are the to-be-cut positions of the board strip A, the board strip B and the board strip C, B1 is located between A1 and A2, B1 is also located between C1 and C2, A1 is located in front of C1, and A2 is located in front of C2.

[0046] In the actual processing process, the plate 7 is first controlled to be conveyed to A1 and located below the cutting module 51, the left cutting module 51 is controlled to cut only A1; then the plate 7 is conveyed to C1 and located below the cutting module 51, the right cutting module 51 is controlled to cut only C1, the plate 7 is conveyed to A2 and located below the cutting module 51 to cut, then the plate 7 is conveyed to C2 and located below the cutting module 51 to cut, when A2 and C2 are cut again, B1 has passed the cutting module 5, and therefore after A2 and C2 are cut again, B1 is exposed, then the plate 7 is controlled to retreat to B1 by the retreat mechanism 6 and located below the cutting module 51, and the cutting module 51 can cut B1.

[0047] The implementation principle of the plate striping method is that, based on the above striping method, the plate 7 with different widths and different lengths can be processed in batches in the same batch according to a specific order and in cooperation with the plate 7 retreat mode, without cutting each single board strip after striping, and the efficiency is higher.

[0048] The above are preferred embodiments of the application, and do not limit the protection scope of the application, so that: equivalent changes made according to the structure, shape and principle of the application should be covered in the protection scope of the application.
