Description
Technical Field
The application relates to a hard and brittle material cutting equipment technology, in particular to a slicing machine.
Background
A slicer is a device that slices a bar of hard and brittle material through a cutting line. Current microtomes include: the cutting device comprises a cutting main roller, a steering mechanism, a tension mechanism, a wire arrangement mechanism and a winding and unwinding mechanism, wherein a cutting wire is wound out of the winding and unwinding mechanism; then the cutting line sequentially enters a cutting main roller through a line arranging mechanism, a tension mechanism and a steering mechanism, and the cutting line is wound on the cutting main roller for a plurality of circles to form a cutting line net for cutting the hard and brittle material rod. The winding and unwinding mechanism winds the cutting lines uniformly in the moving process or releases the winding and unwinding mechanism uniformly; a tension wheel in the tension mechanism is used for adjusting the tension of the cutting wire; the steering mechanism is used for changing the direction of the cutting wire so as to lead the cutting wire wound out of the cutting main roller to the tension mechanism. Usually, a plurality of intermediate wheels are further provided between the above mechanisms for supporting the cutting line.
The line of cut needs to pass through line wheel more than 6 in traditional slicer between line reciprocating motion is received to the cutting home roll and is taken over paying out machine, and line wheel quantity too much can lead to the coplanarity between the line wheel poor, and factors such as inertia, the rotational resistance of line wheel can lead to the adverse effect to the tensile stability of cut line. Too much the quantity of line wheel also can cause the additional tension of whole slicer very big, and then leads to the tension fluctuation amplitude of cutting line great, has further reduced tensile stability.
Generally, the tension mechanism is capable of providing the cutting wire with a tension = static breaking force of the cutting wire-amplitude of the tension fluctuation. Too large a fluctuation amplitude of the tension causes a reduction in the tension that the tension mechanism can provide to the cutting wire, which can reduce the cutting ability of the cutting wire, ultimately affecting the cutting efficiency.
In addition, the cutting line is gradually thinned, the breaking tension of the cutting line is smaller and smaller, the ratio of tension fluctuation caused by factors such as poor inertia, rotation resistance and coplanarity of the line wheel is higher and higher, and the requirement on the control precision of a tension mechanism is higher and higher. If the fluctuation range of the tension and the additional tension caused by the guide wheel factors are kept unchanged, the cutting capability of the cutting line is further reduced, the cutting quality is difficult to ensure, and the development of the thinning of the cutting line is hindered.

The take-up and pay-off mechanisms 3 are positioned on two sides of the cutting mechanism 1. The take-up and pay-off mechanism 3 includes a take-up and pay-off roller 31 that is axially reciprocable. The tension pulley 21 corresponds to the cutting mechanism 1 and the take-up and pay-off mechanism 3 respectively, so that the cutting line wound out by the cutting mechanism 1 is guided and stored in the take-up and pay-off roller 31 through the tension pulley 21, and/or the cutting line released by the take-up and pay-off roller 31 is guided and wound in the cutting mechanism 1.

According to the scheme, all functions of the reversing mechanism, the tension mechanism, the winding and unwinding mechanism and the winding and unwinding mechanism in the original scheme can be realized only by the tension mechanism and the winding and unwinding mechanism, so that the number of parts and maintenance times are reduced, the installation complexity and maintenance times are reduced, and the dead weight is favorably reduced; on the other hand, the cutting line no longer passes through the reversing wheel or the wire arranging wheel, the number of the wire wheels through which the cutting line passes is reduced, the problem of low tension stability caused by factors such as coplanarity of each wire wheel, the rotational inertia of the wire wheels, the rotational resistance of the wire wheels and the like in the traditional scheme is also solved, the fluctuation range of the tension of the cutting line is reduced, the additional tension of the cutting line is further reduced, the tension which can be applied to cutting by a tension mechanism is improved, the cutting capacity of the cutting line is improved, the tension stability of a wire net is improved, the tension of the cutting line meets the cutting requirements, the cutting quality and efficiency are guaranteed, the yield and the production efficiency are further improved, the requirement of thinning of the cutting line is met, the silicon loss is reduced, and the utilization rate of a silicon rod is improved.
Specifically, the cross section of the main cutting roller 11 is circular, the outer circumferential surface of the main cutting roller is provided with a plurality of cutting wire grooves for accommodating cutting wires, the cutting wires enter the cutting wire grooves of the other main cutting roller 11 from the cutting wire grooves of the one main cutting roller 11, and the cutting wire is sequentially wound one by one to form a cutting wire net. The cutting line can be wound into the cutting mechanism 1 from any cutting line groove on any cutting main roller 11 or wound out of the cutting mechanism 1, and the cutting line groove wound into or wound out of the cutting line is called a target cutting line groove. For example: with the three-roll structure shown in fig. 3, the cutting line is wound into the cutting main roll 11 from the target cutting line slot at one end of the lower cutting main roll 11, then wound on the three cutting main rolls 11 in a clockwise or counterclockwise direction, and finally wound out from the target cutting line slot at the other end of the lower cutting main roll 11.
Fig. 4 is a schematic structural diagram of a main cutting roller and a wire groove of a tension pulley in a microtome according to an embodiment of the present disclosure, and fig. 4 is a top view. As shown in fig. 4, the cutting main roller 11 is provided with a plurality of cutting line grooves 111, and the tension pulley 21 is provided with a tension line groove 211. The cutting line groove 111 is arranged corresponding to the tension line groove 211, so that the cutting line is directly wound into the tension line groove 211 after being wound out from the cutting line groove 111, or directly wound into the cutting line groove 111 after being wound out from the tension line groove 211.
As shown in fig. 7 and 8, the take-up and pay-off mechanism 3 includes a take-up and pay-off roller 31 and a take-up and pay-off rotation driver for driving the take-up and pay-off roller 31 to rotate. The cutting wire 7 wound from the other side of the tension pulley 21 is wound around and stored in the take-up and pay-off roller 31, and the cutting wire wound from the take-up and pay-off roller 31 may be wound around the tension pulley 21. Specifically, the tension line groove 211 of the tension wheel 21 is aligned with the take-up and pay-off roller 31, that is, the projection of the plane of the tension line groove 211 toward the take-up and pay-off mechanism is on the take-up and pay-off roller 31, so that the cutting line wound out of the tension line groove 211 is guided to the take-up and pay-off roller 31 through the tension wheel 21, or the cutting line wound out of the take-up and pay-off roller 31 is guided to the tension line groove 211.
In the scheme, the cutting line wound on the take-up and pay-off roller 31 is wound out and directly enters the cutting main roller 11 through the tension pulley 21; the cutting line wound from the cutting main roller 11 passes directly through the tension pulley 21 and is then stored in the take-up and pay-off roller 31. The tension pulley 21 functions as a reversing pulley mechanism in the conventional solution, namely: and changing the direction of the cutting line wound out of the cutting main roller, and guiding the cutting line to wind into the winding and unwinding roller.
The cutting line reciprocates among the take-up and pay-off mechanism 3, the tension mechanism 2 and the cutting mechanism 1, and the silicon rod is cut.
The axis of the cutting main roller 11 and the axis of the tension pulley 21 may be parallel or non-parallel. For the above-mentioned cutting wire casing 111 and tension wire casing 211's corresponding relation, can have multiple form:
1. the cutting line groove 111 (i.e., the target cutting line groove) into and out of the cutting line forms a plane parallel to the plane formed by the tension line groove 211. In this case, the target cutting line slot and the tension line slot 211 may be opposite (as shown in fig. 4) or may be staggered, as long as the cutting line can be ensured to wind around the target cutting line slot and the tension line slot 211 and move smoothly therebetween.
2. The plane formed by the cutting line groove 111 (i.e., the target cutting line groove) into and out of the cutting line is not parallel to the plane formed by the tension line groove 211. In this case, the ends of the target cutting line slot and the tension line slot 211 close to each other are aligned or staggered, so long as the cutting line can be ensured to be wound around and smoothly move between the target cutting line slot and the tension line slot 211.
Both of these are the positions of the tension pulley 21 when it is static, as shown in fig. 4. During operation of the microtome, the tension pulley 21 also oscillates to accommodate variations in the tension of the cutting wire, as shown in figures 5 and 6.
The tension wheel 21 may have one tension line slot or more than two tension line slots. When the tension pulley 21 is provided with a plurality of tension line grooves, the cutting line groove in the present embodiment refers to a tension line groove around which a cutting line is wound.
In the top view shown in fig. 4, the axis of the tension pulley 21 extends in the horizontal direction, or the axis of the tension pulley 21 may form an angle with the horizontal plane (as shown in fig. 5 and 6), which may be an acute angle or a right angle. When at right angles, the axis of the tension pulley 21 extends in the vertical direction. One embodiment is: the plane of the tension line slot 211 is vertical to the axial line of the tension wheel 21, so that the included angle between the plane of the tension line slot 211 of the tension wheel 21 and the plane of the cutting line slot 111 on the cutting main roller 11 for getting out of the cutting line is [0, 90 degrees ].
The difference between fig. 5 and 6 is that the cutting wire 7 is wound into or out of the cutting mechanism 1 from a different cutting wire slot 111.
The included angle between the axial direction of the take-up and pay-off roller 31 and the axial direction of the cutting main roller 11 is [0 degrees, 90 degrees ]. In the solution shown in fig. 1 to 3, the take-up and pay-off roller 31 has an axial direction parallel to the axial direction of the cutting main roller 11, i.e. at an angle of 0 °.
The axial direction of the take-up and pay-off roller 31 and the axial direction of the tension pulley 21 can be parallel (as shown in fig. 7), can also be perpendicular, and can also form other angles (as shown in fig. 8). In the solutions of fig. 1 to 3, the axial direction of the take-up and pay-off roller 31 is parallel to the axial direction of the tension pulley 21, but in the actual operation process, because the tension pulley 21 can swing, a certain included angle exists between the axial direction of the take-up and pay-off roller 31 and the axial direction of the tension pulley 21.
Further, the tension mechanism 2 further includes: and a tension wheel driving mechanism for driving the tension wheel 21 to move along the axial direction of the cutting main roller 11, so that the tension line groove 211 can move to correspond to different cutting line grooves 111.
The present embodiment provides an implementation: the number of the tension mechanisms 2 is two, one tension mechanism 2 corresponds to one target cutting wire slot in the cutting mechanism 1, and the other tension mechanism 2 corresponds to the other target cutting wire slot in the cutting mechanism 1. The number of the take-up and pay-off mechanisms 3 is two, the take-up and pay-off mechanisms are in one-to-one correspondence with the tension mechanisms 2, the two take-up and pay-off mechanisms 3 alternately take up and pay off, so that the cutting lines can move back and forth among the two take-up and pay-off mechanisms 3, the two tension mechanisms 2 and the cutting mechanism 1, and the two target cutting line grooves alternately lead out and in.
Based on the above technical solution, this embodiment provides several implementation modes:
as for the cutting mechanism 1, it may include: the cutting mechanism comprises upper and lower rows of cutting main rollers 11, wherein the upper row comprises at least two cutting main rollers 11, the lower row comprises at least one cutting main roller 11, and the cutting line winds in or out of the cutting mechanism from the top of the upper row of cutting main rollers 11 or the bottom of the lower row of cutting main rollers 11.
Alternatively, the cutting mechanism 1 may include: a row of at least two cutting main rollers 11 arranged horizontally, the cutting line being wound from the top or bottom of the cutting main rollers 11 into or out of the cutting mechanism.
The embodiment provides a specific implementation manner of a slicing machine:
as shown in fig. 1 and 2, a cutting space is provided at an upper portion of the cutting frame 4, and the cutting mechanism 1 is disposed in the cutting space. The upper portion both sides of cutting frame are equipped with side opening, and side opening part mountable cutting room door, the cutting room door can overturn and open or reciprocate to open, make things convenient for operating personnel to carry out threading, maintenance and observation. In the cutting operation process, the cutting chamber door is closed to prevent the water vapor, the oil mist and the like in the cutting space from being sprayed out, and the personal safety of operators is also ensured.
The front end and the rear end of the upper part of the cutting frame 4 are provided with openings for accommodating bearing boxes, the bearing boxes are arranged in the openings, and the two ends of the cutting main roller are fixed and supported through the bearing boxes.
The two sides of the lower part of the cutting frame 4 are respectively provided with a wire winding and unwinding space, and the wire winding and unwinding mechanism 3 is arranged in the wire winding and unwinding space. In order to reduce the interference between the take-up and pay-off mechanisms 3 on the two sides, a vertical partition wall is arranged at the lower part of the cutting frame 4 to separate the take-up and pay-off spaces on the two sides.
The tension mechanism 2 is arranged outside the cutting frame 4, and the tension wheel 21 is lower than the cutting mechanism 1 and higher than the take-up and pay-off roller 31. Cutting line through holes are formed in the side wall of the cutting frame 4, cutting lines wound out of the cutting mechanism 1 penetrate through the cutting line through holes and then are wound on the tension pulley 21, and cutting lines wound out of the tension pulley 21 penetrate through the cutting line through holes and then are wound into the cutting mechanism 1. Avoid the cutting line to walk the line from the side opening, can not cause the influence to cutting room door.
The feeding mechanism 5 is arranged at the top of the cutting frame 1 and drives the silicon rod to move downwards. When moving between the two cutting main rollers, the silicon rod is cut by the cutting line between the two cutting main rollers 11.
The slicer still includes: and the liquid cooling system sprays cooling liquid with lower temperature onto the cutting wire net, reduces the temperature of the cutting wire net, and can wash away silicon powder attached to the cutting wire net, so that the cutting surface of the silicon rod meets the requirements, and the yield is guaranteed. And a cooling liquid recovery and filtering device is arranged below the cutting main roller, and the cooling liquid is recovered, filtered and recycled.
The slicer still includes: and a lubricating system for supplying lubricating oil to rotating parts (such as bearings of a cutting main roller and bearings of a take-up and pay-off roller) in the slicing machine.
Based on the above technical solution, this embodiment provides several layout examples of the cutting mechanism 1, the tension mechanism 2, and the take-up and pay-off mechanism 3.
Example one:
fig. 9 is a schematic view of a first layout of various mechanisms in a microtome according to an embodiment of the present disclosure. As shown in fig. 9, the cutting mechanism 1 includes three cutting main rollers 11 forming a triangle, two cutting main rollers 11 are disposed above the three cutting main rollers, one cutting main roller 11 is disposed below the three cutting main rollers, and the upward projection of the lower cutting main roller 11 is located between the two cutting main rollers 11 in the upper row. The cutting line is wound in and out of the cutting mechanism 1 from the bottom of the lower cutting main roller 11. The cutting line between the upper two cutting main rollers 11 is used for cutting the silicon rod moving from top to bottom.
Seen from the moving direction of the cutting line, the cutting line 7 winds into the cutting structure 1 from a first cutting line groove at the bottom of the lower cutting main roller 11, and winds out of the cutting structure 1 from a second cutting line groove at the bottom of the lower cutting main roller 11; when the cutting line moves in the opposite direction, the cutting line 7 winds from the second cutting line groove at the bottom of the lower cutting main roller 11 into the cutting structure 1, and winds from the first cutting line groove at the bottom of the lower cutting main roller 11 out of the cutting structure 1.
The two groups of tension mechanisms 2 are respectively positioned at two sides of the cutting mechanism 1 and can be symmetrically arranged. The axis of the tension pulley 21 is lower than the axis of the lower row of cutting main rollers 11, and specifically, the top end of the tension pulley 21 is lower than the bottom end of the cutting main rollers 11. The tension driver 22 drives the lower tension pulley 21 to swing left and right to adjust the tension of the cutting line 7. The axis of the tension pulley 21 in a static state is parallel to the axis of the cutting main roller 11, and the axis of the tension pulley 21 is changed during the cutting operation.
The two sets of take-up and pay-off mechanisms 3 are respectively positioned at two sides of the cutting mechanism 1 and can be symmetrically arranged. In fig. 9, the axis of the take-up and pay-off roller 31 is parallel to the axis of the cutting main roller 11. The tension pulley 21 is located at the outer side of the take-up and pay-off roller 31, and the cutting line passes through the tension pulley 21 and then is stored in the take-up and pay-off roller 31.
One winding direction is: the cutting line 7 winds around the tension pulley 21 leftwards after being wound out from the left take-up and pay-off roller 31, then extends towards the upper right, winds into the cutting mechanism from the bottom of the lower cutting main roller 11, winds around the three cutting main rollers 11 along the anticlockwise direction, winds out the cutting mechanism from the bottom of the lower cutting main roller 11, extends towards the lower right and winds around the tension pulley 21 arranged on the right, and then is stored inwards in the corresponding take-up and pay-off roller 31. During operation of the microtome, the cutting wire is moved back and forth along the same path, namely: the forward movement is the same as the winding direction, and the reverse movement is the opposite of the winding direction.
In the scheme, each mechanism is compact in structure, and arrangement of the wire wheels is facilitated. And the cutting main roller is closer to the tension pulley, and the take-up and pay-off roller is also closer to the tension pulley, so that the cross-line distance of the cutting line is compact, and the tension stability is better.
For the above solution, this example provides another winding method: fig. 10 is a schematic view of another winding method for the first layout of the various mechanisms in the slicer according to the embodiment of the present application. As shown in fig. 10, the cutting line 7 is wound from the left take-up and pay-off roller 31, then obliquely passes over the right tension pulley 21 from above, then extends to the left upper side, is wound into the cutting mechanism from the bottom of the lower cutting main roller 11, is wound around the three cutting main rollers 11 in the clockwise direction, is wound out of the cutting mechanism from the bottom of the lower cutting main roller 11, extends to the left lower side, is wound around the left tension pulley 21, extends to the right lower side, and is stored in the right take-up and pay-off roller 31.
Example two
The only difference between the example and the example is that the cutting mechanism 1 is different, and the structure and layout of the tension mechanism 2 and the take-up and pay-off mechanism 3 are the same as those of the example I.
Fig. 11 is a schematic diagram of a second layout of various mechanisms in a microtome according to an embodiment of the present disclosure. As shown in fig. 11, the cutting mechanism 1 includes two horizontally arranged cutting main rollers 11, and the cutting line 7 is wound in or out from the top or bottom of the cutting main rollers 11. Fig. 11 shows a solution in which the cutting line 7 is wound in or out from the bottom of the cutting main roller 11. The silicon rod moves from top to bottom, and the cutting line between the tops of the two cutting main rollers 11 cuts the silicon rod.
The cutting line 7 winds from the bottom of the right cutting main roller 11 into the cutting structure 1 and winds from the bottom of the left cutting main roller 11 out of the cutting structure 1, as seen from the direction of movement of the cutting line; when the cutting line is moved in the reverse direction, the cutting line 7 winds from the bottom of the left cutting main roller 11 into the cutting structure 1 and winds from the bottom of the right cutting main roller 11 out of the cutting structure 1.
Taking the scheme shown in fig. 11 as an example, one winding direction is: the cutting line 7 winds from the left take-up and pay-off roller 31, obliquely winds around the tension pulley 21 towards the left upper side, then extends towards the right upper side, winds into the cutting mechanism from the bottom of the right cutting main roller 11, winds around the two cutting main rollers 11 along the anticlockwise direction, winds out of the cutting mechanism from the bottom of the left cutting main roller 11, extends towards the right lower side, winds around the tension pulley 21 arranged on the right side, and then is stored inwards in the corresponding take-up and pay-off roller 31. During operation of the slicer, the cutting wire is moved back and forth along the same path, namely: the forward movement is the same as the winding direction, and the reverse movement is the opposite of the winding direction.
For the above solution, this example provides another winding method: fig. 12 is a schematic view of another winding method for a second layout of various mechanisms in a microtome according to an embodiment of the present disclosure. As shown in fig. 12, after being wound from the left take-up and pay-off roller 31, the cutting line 7 obliquely passes over the right tension pulley 21 from above, then extends to the left upper side, is wound into the cutting mechanism from the bottom of the left cutting main roller 11, is wound around the two cutting main rollers 11 in the clockwise direction, is wound out of the cutting mechanism from the bottom of the right cutting main roller 11, extends to the left lower side, is wound around the left tension pulley 21, extends to the right lower side, and is stored in the right take-up and pay-off roller 31.

Fig. 13 is a schematic view of a third layout of various mechanisms in a microtome according to an embodiment of the present disclosure. As shown in fig. 13, the cutting mechanism 1 includes three cutting main rollers 11 forming a triangle, two of the cutting main rollers 11 being on top and one of the cutting main rollers 11 being on bottom. The cutting line is wound into or out of the cutting mechanism 1 from the top of the upper two cutting main rollers 11. The cutting line between the upper two cutting main rollers 11 is used for cutting the silicon rod moving from top to bottom.
Taking the scheme shown in fig. 13 as an example, one winding direction is: the cutting line 7 winds from the take-up and pay-off roller 31 on the left, obliquely winds around the tension pulley 21 towards the upper left, then extends towards the upper right, winds into the cutting mechanism from the top of the cutting main roller 11 on the left, winds around the three cutting main rollers 11 in the clockwise direction, winds out the cutting mechanism from the top of the cutting main roller 11 on the right, extends towards the lower right, winds around the tension pulley 21 on the right, and then is stored inwards in the corresponding take-up and pay-off roller 31. During operation of the microtome, the cutting wire is moved back and forth along the same path, namely: the forward movement is the same as the winding direction, and the reverse movement is the opposite of the winding direction.
According to the scheme provided by the example, the layout of the tension mechanism 2 and the take-up and pay-off mechanism 3 is simple, and the wiring process is simple.
Example four
The only difference between the example and the third example is that the cutting mechanism 1 is different, and the structure and layout of the tension mechanism 2 and the take-up and pay-off mechanism 3 are the same as those of the first example.
Fig. 14 is a schematic diagram illustrating a fourth layout of various mechanisms in a microtome according to an embodiment of the present disclosure. As shown in fig. 14, the cutting mechanism 1 includes two horizontally arranged cutting main rollers 11, and the cutting line 7 is wound in or out from the top of the cutting main rollers 11. The silicon rod moves from top to bottom, and the cutting line between the tops of the two cutting main rollers 11 cuts the silicon rod.
Taking the scheme shown in fig. 14 as an example, one winding direction is: the cutting line 7 winds from the left take-up and pay-off roller 31, obliquely winds around the tension pulley 21 to the left upper side, then extends to the right upper side, winds into the cutting mechanism from the top of the left cutting main roller 11, winds around the two cutting main rollers 11 in the clockwise direction, winds out of the cutting mechanism from the top of the right cutting main roller 11, extends to the right lower side, winds around the tension pulley 21 arranged on the right side, and then is stored inwards in the corresponding take-up and pay-off roller 31. During operation of the microtome, the cutting wire is moved back and forth along the same path, namely: the forward movement is the same as the winding direction, and the reverse movement is the opposite of the winding direction.
The scheme that this example provided, tension mechanism 2 is comparatively simple with the overall arrangement of receiving and paying out machine structure 3, and the wiring process is also simple.
