Description

Technical Field

[0001] The invention relates to the field of slicers for cutting hard and brittle materials, and in particular to a cutting device with a cutting line support roller that can be adjusted steplessly and a stepless adjustment method. Background Art

[0002] The cutting machine is usually provided with three sets of support roller assemblies for winding the cutting wire, and the three support roller assemblies are arranged in a triangular manner, with two support roller assemblies arranged on the upper side and one support roller assembly arranged on the lower side. The spacing between the three support roller assemblies on the existing cutting device is fixed, and cannot be adjusted according to the width of different hard and brittle material bars (such as silicon ingots) to be cut, resulting in the failure to ensure cutting efficiency and cutting yield.

[0003] To this end, the applicant has designed a new solution and applied for an invention patent, which has been authorized. The patent number is "ZL202010602778.5", and the patent name is "A device and method for changing the center distance of a slicer guide wheel". The technical solution disclosed in the patent is: a device for changing the center distance of a slicer guide wheel, including a cutting chamber frame, and a rotatable front dividing plate and a rear dividing plate are respectively installed on both sides of the cutting chamber frame, and a plurality of support roller assemblies are installed between the front dividing plate and the rear dividing plate, and the center distances between adjacent support roller assemblies are set differently. The present invention solves the problem that the center distance between the two guide wheels cannot be changed by setting a dividing plate structure and arranging unequally spaced guide wheel devices on the dividing plate, so that the center distance between adjacent guide wheels can be selected in multiple gears, which can be suitable for cutting hard and brittle materials of various specifications and sizes, and improves the limitation that the slicer can only cut a single specification and size. When adjusting, you only need to rotate the dividing plate, which is simple and convenient to operate.

[0004] Since, in the technical solution involved in the prior patent of the applicant, once the front indexing plate and the rear indexing plate are set on the cutting device, the spacing between the two adjacent support roller assemblies in the three support roller assemblies is fixed, it is difficult to adapt to the increasing demand for the specification size of hard and brittle material rods. If it is necessary to meet the requirements of hard and brittle material rods of various specifications and sizes, it is necessary to replace different front indexing plates and rear indexing plates to change the spacing between the two adjacent support roller assemblies. Therefore, it is necessary to equip the front indexing plates and rear indexing plates of various specifications, which increases the cost of equipping the front indexing plates and rear indexing plates of various specifications. At the same time, it is relatively complicated to replace the front indexing plates and the rear indexing plates, the replacement efficiency is low, and the replacement intensity of the staff is large. Summary of the invention

[0005] The purpose of the present invention is to solve the above-mentioned problems existing in the prior art and to provide a cutting device and a stepless adjustment method for the cutting line support roller. A stepless adjustment component is arranged between the support roller assemblies. By adjusting the stepless adjustment component, the spacing between the first support roller assembly and the second support roller assembly can be steplessly adjusted, and the height of the third support roller assembly from the plane where the first support roller assembly and the second support roller assembly are located can be steplessly adjusted, so as to adjust the spacing between adjacent support roller assemblies. The adjustment is not only convenient, but also has high adjustment efficiency, and the adjustment intensity of the staff is greatly reduced, which is beneficial to improving the working efficiency of the cutting device.

[0009] In the technical solution, the stepless adjustment component is used to steplessly adjust the distance between the first support roller assembly and the second support roller assembly, and to steplessly adjust the height of the third support roller assembly from the plane where the first support roller assembly and the second support roller assembly are located. By arranging a stepless adjustment component between the support roller assemblies, it is used to steplessly adjust the distance between the first support roller assembly and the second support roller assembly, and to steplessly adjust the height of the third support roller assembly from the plane where the first support roller assembly and the second support roller assembly are located, so as to adjust the distance between adjacent support roller assemblies, which is not only convenient to adjust, but also has high adjustment efficiency, and greatly reduces the adjustment intensity of the staff, which is conducive to improving the working efficiency of the cutting device.

[0010] As a further improvement and supplement to the above technical solution, the present invention adopts the following technical measures: the stepless adjustment component includes an adjustment member and a support member, the adjustment member is arranged between the first support roller assembly and the second support roller assembly, and is used to steplessly adjust the distance between the first support roller assembly and the second support roller assembly, and steplessly adjust the height of the third support roller assembly from the plane where the first support roller assembly and the second support roller assembly are located, and the support member is arranged below the third support roller assembly, and is used to support the third support roller assembly.

[0011] As a preference, the first support roller assembly and the second support roller assembly are arranged at the top, and the third support roller assembly is arranged at the bottom. The adjusting member is used not only to adjust the spacing between the first support roller assembly and the second support roller assembly (i.e. the spacing in the width direction or the spacing in the horizontal direction), but also to adjust the distance from the third support roller assembly to the plane where the first support roller assembly and the second support roller assembly are located (i.e. the distance in the height direction or the distance in the vertical direction, or the distance between the third support roller assembly and the first support roller assembly or the second support roller assembly). Moreover, by steplessly adjusting the thickness and height of the adjusting member, the distance between the first support roller assembly and the second support roller assembly, and the distance from the third support roller assembly to the plane where the first support roller assembly and the second support roller assembly are located can be steplessly adjusted, and the stepless adjustment is convenient, accurate and efficient.

[0012] Preferably, an assembly cavity is provided on the base, and the assembly cavity has a transverse guide cavity and a vertical guide cavity. The first bearing seat on the first support roller assembly and the second bearing seat on the second support roller assembly are arranged in the transverse guide cavity, and the third bearing seat on the third support roller assembly is arranged in the vertical guide cavity. The adjustment member is arranged between the first bearing seat and the second bearing seat, and the lower end of the adjustment member is pressed against the upper end of the third bearing seat. By adjusting the thickness and height of the adjustment member, the spacing between the first bearing seat and the second bearing seat, and the distance from the third bearing seat to the plane where the first bearing seat and the second bearing seat are located are steplessly adjusted. The transverse guide cavity is not only used to accommodate and assemble the first bearing seat and the second bearing seat, but also used to guide the left and right movement of the first bearing seat and the second bearing seat. Similarly, the vertical guide cavity is used to accommodate the third bearing seat and guide the up and down movement of the third bearing seat, which is conducive to improving the reliability and accuracy of stepless adjustment.

At the same time, the tie rod fastens the first bearing seat, the second bearing seat and the adjusting member, which is conducive to improving the stability of the setting of the first bearing seat, the second bearing seat and the adjusting member.

[0014] Preferably, the assembly cavity is in an inverted "pin" shape. The first bearing block, the second bearing block, and the third bearing block are all square-shaped.

[0016] Preferably, the supporting member is in clearance fit with the lower wall of the assembly cavity, for reserving a space to enable stepless adjustment of the upward or downward movement of the third bearing block, or the supporting member fills the lower space between the third bearing block and the assembly cavity. After steplessly adjusting the third bearing block, select a supporting member with a suitable thickness according to the size of the lower space between the third bearing block and the assembly cavity, so that the supporting member stably supports the third bearing block.

[0017] Preferably, the adjusting member and the supporting member are fixedly arranged on the base in a position-adjustable manner through a connecting member.
