Composite roll slitting machine

Abstract

This utility model relates to a composite roll slitting machine, comprising: an unwinding roller for unwinding; a take-up roller for rewinding; and a slitting assembly disposed between the unwinding roller and the take-up roller for slitting the roll material. The slitting assembly includes a rotatable central shaft and multiple sets of circular blades spaced upwards along the central shaft axis. An axial limiting section is provided circumferentially on the central shaft, and the axial limiting section includes radial teeth closely laid out axially. This utility model abandons the method of positioning and adjusting the blades by pre-setting mounting holes on the shaft body. Instead, it uses an axial limiting section circumferentially on the central shaft, which includes radial teeth closely laid out axially. The circular blades are positioned by the engagement of radial teeth with the radial key of the fixing assembly. This method overcomes the limitations of low adjustment accuracy, fixed position, and limited adjustment range of pre-set mounting holes, enabling precise adjustment and locking of the circular blades at any position along the central shaft axis.

Description

Technical Field

[0001] This utility model belongs to the field of roll material slitting technology, and specifically relates to a composite roll material slitting machine. Background Technology

[0002] In the deep processing of metal coils, the slitting process is a key step in cutting wide metal coils into narrow coils according to specific specifications, which directly determines the processing accuracy of subsequent forming, stamping, welding and other processes.

[0003] In existing technologies, to accommodate the slitting requirements of metal coils with different widths, the cutter body often needs to be adjusted axially. However, existing adjustment methods all have drawbacks, such as:

[0004] Pre-set mounting holes on the shaft body are used to position and adjust the tool body, but this method has low adjustment accuracy, fixed adjustment position, and limited adjustment range.

[0005] Alternatively, set screws can be used to fix the cutter body and the shaft relatively, but as the cutter body comes into contact with the metal coil, the set screws may loosen, causing relative movement between the cutter body and the shaft. Utility Model Content

[0006] This utility model addresses the problems of existing technologies by providing a composite roll slitting machine, the specific technical solution of which is as follows:

[0007] Composite roll slitting machine, including:

[0008] Unwinding rollers used for unwinding;

[0009] Take-up rollers used for winding;

[0010] And a slitting assembly for slitting rolls, located between the unwinding roll and the take-up roll;

[0011] The slitting assembly includes a rotatable central shaft and multiple sets of circular blades spaced upward along the central shaft axis. The central shaft is provided with an axially restricting section in the circumferential direction, and the axially restricting section includes radial teeth closely laid in the axial direction.

[0012] The circular cutter body is provided with a fixing component corresponding to the axial limiting section. The fixing component includes a radial key, a fixing member and a screw. The fixing member is installed on the circular cutter body, the screw is screwed to the fixing member, and the radial key is rotatably connected to the end of the screw. When the screw rotates, it can drive the radial key to slide inward and engage the radial teeth on the axial limiting section.

[0013] As a further technical solution of this utility model, the axial limiting segment is provided in multiple sets, which are evenly distributed around the central axis in the circumferential direction.

[0014] As a further technical solution of this utility model, a circumferential limiting section is provided in the circumferential direction of the central axis, the circumferential limiting section includes axial teeth closely arranged in the circumferential direction, and the inner side of the circular cutter body has an axial tooth groove corresponding to the circumferential limiting section.

[0015] As a further technical solution of this utility model, the circumferential limiting segment is provided in multiple sets, and the circumferential limiting segment and the axial limiting segment are alternately arranged along the central axis circumferentially.

[0016] The beneficial effects of this utility model are as follows:

[0017] (1) In this application, a gear-type axial adjustment and locking structure is used to replace the traditional mounting hole positioning:

[0018] Instead of using pre-set mounting holes on the shaft to position and adjust the cutter body, this method adopts an axial limiting section set around the central shaft. This limiting section contains radial teeth closely laid along the axial direction. The circular cutter body is positioned by the engagement of the radial teeth key of the fixing component with the radial teeth. This method overcomes the limitations of low adjustment accuracy, fixed position and limited adjustment range of pre-set mounting holes. It can achieve precise adjustment and locking of the circular cutter body at any position in the central shaft axial direction, significantly improving the flexibility and accuracy of adjustment.

[0019] (2) The circumferential and axial restriction sections are arranged alternately:

[0020] The central shaft is also equipped with a circumferential limiting section, which includes axial teeth arranged closely along the circumference. The inner side of the circular cutter body is correspondingly provided with axial tooth grooves. The two work together to prevent relative circumferential rotation between the central shaft and the circular cutter body during rotation, ensuring the effective transmission of cutting power. At the same time, the circumferential limiting section and the axial limiting section are arranged alternately along the circumferential direction of the central shaft, further ensuring the uniformity of the mass distribution of the central shaft. While realizing the circumferential limiting function, it also maintains the balance of the equipment rotation. Attached Figure Description

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0029] Figure 1 A schematic diagram of the overall structure of the composite roll slitting machine is shown; Figure 2 A schematic diagram of the slitting assembly 300 is shown; Figure 3 A schematic diagram of the structure of the central shaft 310 is shown; Figure 4 A schematic diagram of the circular cutter body 320 is shown; Figure 5 A structural schematic diagram of the fixing component 400 is shown.

[0030] Figure 1 The composite roll slitting machine includes an unwinding roller 100 for unwinding, a winding roller 200 for winding, and a slitting assembly 300 disposed between the unwinding roller 100 and the winding roller 200 for slitting the roll. The roll is unwound by the unwinding roller 100 and wound up by the winding roller 200, while the slitting assembly 300 is disposed on the travel path of the roll and can slit the roll longitudinally.

[0031] Figure 2 In the slitting assembly 300, there is a rotatable central shaft 310 and multiple circular blades 320 arranged axially and spaced upward along the central shaft 310. The multiple circular blades 320 are spaced apart axially. When the slitting assembly 300 rotates as a whole, the multiple circular blades 320 longitudinally slit the roll material into strips.

[0032] It should be noted that in actual use, the central shaft 310 is externally driven to achieve the rotation and cutting of the slitting component 300, and the multiple sets of circular blades 320 on the central shaft 310 can be equidistant or variable-pitch, which can be set according to specific needs without limitation.

[0033] Figures 3-5In the middle, the central shaft 310 is provided with an axially restricting section 311 in the circumferential direction. The axially restricting section 311 includes radial teeth closely laid in the axial direction. The circular cutter body 320 is provided with a fixing component 400 corresponding to the axially restricting section 311. The fixing component 400 includes a radial key 410, a fixing member 420, and a screw 430. The fixing member 420 is installed on the circular cutter body 320, the screw 430 is screwed to the fixing member 420, and the radial key 410 is rotatably connected to the end of the screw 430. When the screw 430 rotates, it can drive the radial key 410. The radial key 410 slides inward and engages with the radial teeth on the axial limiting section 311. During adjustment, simply rotate the screw 430 to drive the radial key 410 away from the axial limiting section 311 and disengage from the radial teeth. This will drive the circular cutter body 320 to move along the axial direction of the central axis 310 to adjust its position. Once the position is determined, rotate the screw 430 in the opposite direction to drive the radial key 410 to move towards the central axis 310 and engage with the radial teeth on the axial limiting section 311, thus locking the position of the circular cutter body 320.

[0034] It should be noted that multiple sets of axial limiting sections 311 are provided, which are evenly distributed around the central axis 310 in the circumference, so that the overall mass distribution of the central axis 310 is uniform and local imbalance is avoided during rotation.

[0035] The central shaft 310 is provided with a circumferential limiting section 312, which includes axial teeth closely arranged in the circumferential direction. The inner side of the circular cutter body 320 has an axial tooth groove 321 corresponding to the circumferential limiting section 312. The circumferential limiting section 312 and the axial tooth groove 321 cooperate with each other to make the central shaft 310 and the circular cutter body 320 form a whole when rotating, so as to avoid relative rotation. At the same time, it can cooperate with the fixing component 400 to lock the relative position of the central shaft 310 and the circular cutter body 320.

[0036] Multiple sets of circumferential limiting sections 312 are provided, and the circumferential limiting sections 312 and axial limiting sections 311 are alternately arranged along the central axis 310. That is to say, there is an alternating arrangement of one set of axial limiting sections 311, one set of circumferential limiting sections 312, and another set of axial limiting sections 311 around the central axis 310, so that the central axis 310 as a whole still has a uniform mass distribution.

[0037] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
