[0063] This application provides a cutting device for furnace bottom soft felt, which can cut the soft felt in the furnace bottom insulation structure of a single crystal furnace, replacing the current manual cutting, improving the cutting accuracy to a certain extent, and ensuring that the size of the soft felt holes does not deviate. The following is in conjunction with...Figures 1-4 This application provides a detailed description of a cutting device for furnace bottom felt.

[0064] Combination Figures 1-4 As shown, the cutting device for the furnace bottom felt includes a worktable 1, a drive assembly, a cutting assembly, and a support assembly 2.

[0065] Specifically, the drive component is mounted on the worktable 1 via the support component 2, and the support component 2 supports the drive component away from the worktable 1 by a preset distance, thereby creating an installation space 316 between the drive component and the worktable 1; furthermore, combined with Figure 1 As shown, the support component 2 is located above the worktable 1, and the drive component is located on the support component 2, thus creating an installation space 316 between the drive component and the worktable 1.

[0066] Specifically, the cutting assembly is set in the installation space 316. The cutting assembly includes a cutting part and a receiving part for placing soft felt. The output end of the drive assembly is connected to the cutting part, and the receiving part is set on the worktable 1. Furthermore, since the drive assembly and the worktable 1 are at a certain distance, when the cutting part is set on the drive assembly and the receiving part is set on the worktable 1, a cutting space is formed between the cutting part and the receiving part.

[0067] Specifically, the drive assembly can drive the cutting part to move along the first direction 314, causing the cutting part to move towards and cut the soft felt or move away from the soft felt. Further, according to... Figure 1 Taking the placement method as an example, the first direction 314 refers to the vertical direction. That is, when the driving component drives the cutting part to move in a vertically downward direction, the cutting part can cut the soft felt; when the driving component drives the cutting part to move in a vertically upward direction, the cutting part can move away from the soft felt. It is worth noting that the above cutting refers to cutting circular holes in the soft felt.

[0068] In summary, this application utilizes a drive assembly to drive the cutting unit to cut the soft felt. Since the cutting unit has a fixed size, it cuts circular holes of a fixed size. Compared to existing manual cutting methods, the cutting of this application is more precise, and the size of the holes in the soft felt does not deviate. In addition, it replaces manual processing, saving manpower and resources and improving work efficiency.

[0069] In this embodiment, combined with Figure 1 and Figure 4 As shown, the cutting section includes a fixed disk 204 and a cutting blade; combined with Figure 1 As shown, the receiving part is the receiving plate 208.

[0070] Specifically, the fixed plate 204 is circular, connected to the output end of the drive assembly, and a cutting blade is provided on the side of the fixed plate 204 facing the soft felt.

[0071] Specifically, there is at least one cutting blade, and when there are multiple cutting blades, they are arranged at intervals. Furthermore, combined with... Figure 4 As shown, the cutting blade includes a first annular cutting blade 206 and a second annular cutting blade 207, wherein the diameter of the first annular cutting blade 206 is larger than the diameter of the second annular cutting blade 207. Preferably, three first annular cutting blades 206 are provided, arranged at intervals along the diameter of the fixed disk 204, and four second annular cutting blades 207 are provided, arranged in a matrix.

[0072] In summary, when the drive assembly drives the fixed disk 204 to move toward the soft felt, the three first annular cutting blades 206 and the four second annular cutting blades 207 will move toward the soft felt simultaneously and cut the soft felt directly. Since the diameters of the first annular cutting blades 206 and the second annular cutting blades 207 are fixed, the cutting will be more precise and the size of the holes in the soft felt will not deviate.

[0073] In this embodiment, combined with Figure 1 As shown, the support component 2 includes a horizontal plate 202 and a fixing frame 201.

[0074] Specifically, two fixing brackets 201 are provided, and the two fixing brackets 201 are respectively provided at the ends of the worktable 1 along the second direction 317; according to Figure 1 Taking the arrangement in the example, the second direction 317 refers to the left and right direction, that is, one of the fixed brackets 201 is set at the left end of the workbench 1, and the other fixed bracket 201 is set at the right end of the workbench 1.

[0075] Specifically, the horizontal plate 202 extends along the second direction 317 and its two ends are respectively attached to the fixing frame 201 at the left end and the fixing frame 201 at the right end; in other words, the fixing frame 201 and the horizontal plate 202 constitute a frame structure.

[0076] In this embodiment, combined with Figure 1 As shown, the drive assembly includes an electric telescopic rod 203.

[0077] Specifically, the main body of the electric telescopic rod 203 is located on the side of the horizontal plate 202 away from the cutting assembly, and the output end of the electric telescopic rod 203 passes through the horizontal plate 202 and is connected to the fixed plate 204; preferably, the electric telescopic rod 203 is located in the middle position of the horizontal plate 202.

[0078] Specifically, the output end of the electric telescopic rod 203 can drive the fixed plate 204 to move along the first direction 314, so that the cutting blade moves toward the soft felt and cuts the soft felt or moves away from the soft felt.

[0079] More specifically, combined Figure 1 As shown, the drive assembly also includes auxiliary rods 205. Multiple auxiliary rods 205 are provided, and the multiple auxiliary rods 205 are symmetrically arranged about the axis of the electric telescopic rod 203; preferably, combined with... Figure 1 As shown, there are two auxiliary rods 205, which are symmetrically arranged on both sides of the electric telescopic rod 203 about the axis of the electric telescopic rod 203.

[0080] Furthermore, the auxiliary rod 205 passes through the cross plate 202 and connects to the fixed disk 204. When the drive assembly drives the fixed disk 204 to move along the first direction 314, the auxiliary rod 205 can assist the fixed disk 204 in moving along the first direction 314. Preferably, the auxiliary rod 205 and the fixed disk 204 are connected together by a threaded connection.

[0081] In this embodiment, combined with Figure 1 As shown, the cutting device for the furnace bottom soft felt also includes a clamping assembly; the clamping assembly includes a connecting plate 3, a fixing frame 307, a pressure plate 311, and a driving component.

[0082] Specifically, the fixing frame 307 is symmetrically arranged on both sides of the receiving plate along the second direction 317 via the connecting plate 3 about the axis of the receiving plate; combined with Figure 1 As shown, the connecting plate 3 is U-shaped and includes a first connecting segment, a second connecting segment, and a third connecting segment. The first connecting segment and the third connecting segment are respectively disposed at both ends of the second connecting segment, and the first connecting segment and the third connecting segment extend along the second direction 317, while the second connecting segment extends along the first direction 314. In addition, the end of the third connecting segment away from the second connecting segment is connected to the end of the worktable 1 along the second direction 317, and the first connecting segment away from the second connecting segment is connected to the fixed frame 307.

[0083] Specifically, the fixing frame 307 extends along a third direction 318 and has an opening 313 facing the receiving plate. This opening 313 can be used to place the edge of the soft felt along the second direction 317, and the inner bottom wall of the fixing frame 307 is flush with the upper surface of the receiving plate. In actual use, the soft felt is placed on the receiving plate, and the edge of the soft felt along the first direction 314 is placed at the opening 313. Since the inner bottom wall of the fixing frame 307 is flush with the upper surface of the receiving plate, it can be ensured that the soft felt on the receiving plate and the soft felt on the opening 313 are on the same plane, and there will be no unevenness problem.

[0084] Specifically, the pressure plate 311 is disposed in the opening 313 and extends along the third direction 318. The driving member is disposed on the side of the fixed frame 307 away from the worktable 1, that is, the driving member is disposed above the fixed frame 307. The driving member can drive the pressure plate 311 to move along the first direction 314, so that the pressure plate 311 presses or releases the soft felt.

[0085] In summary, the pressure plate 311 is used to press the edges of the soft felt firmly, thereby ensuring that the soft felt remains flat during the cutting process and preventing unevenness of the soft felt from affecting the cutting accuracy.

[0086] In this embodiment, combined with Figure 1 As shown, the clamping assembly also includes an auxiliary column 310 and a crossbar 309;

[0087] The crossbar 309 extends along the third direction 318 and is positioned above the fixed frame 307; the auxiliary column 310 extends along the first direction 314 and is connected at one end to the crossbar 309, and at the other end passes through the fixed frame 307 and is connected to the pressure plate 311.

[0088] Specifically, the driving component is positioned above the fixed frame 307 and its output end is connected to the crossbar 309; when the driving component drives the crossbar 309 to move along the first direction 314, the auxiliary column 310 can drive the pressure plate 311 to move along the first direction 314.

[0089] Preferably, the driving component is an electric cylinder 308.

[0090] In this embodiment, the cutting device for the furnace bottom felt also includes a stretching assembly disposed on the worktable 1; combined with Figure 2 and Figure 3 As shown, the worktable 1 has an internal mounting cavity, and the stretching assembly is disposed within the mounting cavity. The stretching assembly includes a drive unit, a drive gear 302, a driven gear 303, a crankshaft 304, an adjusting rod 305, and a connecting rod 306.

[0091] Specifically, the drive unit is fixed to the top sidewall with the mounting cavity, and the output end of the drive unit is connected to the drive gear 302; the driven gear 303 is meshed with the drive gear 302, and the driven gear 303 and the drive gear 302 are respectively connected to the crankshaft 304.

[0092] Specifically, an adjusting rod 305 extending along a third direction 318 is connected to one end of the crankshaft 304 away from the driving gear 302 and the other end of the crankshaft 304 away from the driven gear 303.

[0093] Specifically, the connecting rod 306 extends along the second direction 317 and is connected to an adjusting rod 305 and a connecting plate 3 at both ends.

[0094] Preferably, the driving unit is a motor 301, which is fixed to the top sidewall with a mounting cavity, and the output shaft of the motor 301 is connected to the drive gear 302.

[0095] In actual use, since the drive gear 302 is connected to the crankshaft 304, and the crankshaft 304 is movably connected to the adjusting rod 305, and since the adjusting rod 305 is connected to the connecting plate 3 through the connecting rod 306 (the connecting rod 306 passes through the side wall of the working platform and connects to the connecting plate 3), when the drive motor 301 is started, the drive motor 301 will drive the drive gear 302 to rotate. The rotating drive gear 302 will cause the connecting rod 306 to move along the second direction 317. When the connecting rod 306 moves along the second direction 317, it will drive the connecting plate 3 to move along the second direction 317. When the connecting plate 3 moves along the second direction 317, it will move the soft felt located in the fixed frame 307 in opposite directions along the first direction 314, that is, straighten the soft felt. This can ensure that the soft felt is always flat and not wrinkled, which further improves the cutting accuracy to a certain extent.

[0096] More specifically, combined Figure 3 As shown, the adjusting rod 305 has a through hole 315 extending along a direction perpendicular to the third direction 318. The end of the crankshaft 304 facing away from the driving gear 302 and the end of the crankshaft 304 facing away from the driven gear 303 are respectively disposed in the through hole 315; so that when the driving gear and the driven gear 303 rotate, the side of the crankshaft 304 facing away from the driving gear and the driven gear 303 can move in the through hole 315.

[0097] More specifically, combined Figure 2 As shown, the stretching assembly also includes a balance plate 312; the balance plate 312 is symmetrically arranged about the axis of the adjusting rod 305; the balance plate 312 extends along the second direction 317 and passes through the adjusting rod 305 connected to the driving gear 302 via the crankshaft 304 and the adjusting rod 305 connected to the driven gear 303 via the crankshaft 304.

[0098] In this embodiment, a rotating shaft is fixedly connected to the top of the driven gear 303, and the top of the rotating shaft is movably connected to the worktable 1 through a bearing. By setting the rotating shaft and the bearing, the operation of the driven gear 303 is stabilized and the driven gear 303 is limited.

[0099] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
