Description

Technical Field

[0001] The invention relates to a vertical feeding device for melting quartz fibers. Background Art

[0002] When processing quartz fiber, it needs to be processed into quartz glass material, and then the method of melting and drawing while feeding is adopted. The existing feeding device generally achieves the purpose of feeding by driving the material clamp downward by a ball screw. However, when using this type of feeding device, on the one hand, the quartz raw material is easy to jump and dislocate during the downward movement, causing unstable fiber quality; on the other hand, after completing a feeding, it is necessary to wait for the screw to drive the material clamp to rise and reset, which affects production efficiency. Summary of the invention

[0003] The object of the present invention is to provide a vertical feeding device for melting quartz fibers, so as to solve the technical problems of low processing efficiency and unstable yarn quality of the existing feeding device.

[0004] The technical solution of the quartz fiber melting vertical feeding device of the present invention: The quartz fiber melting vertical feeding device comprises:

[0005] frame;

[0006] The rolling mechanism is installed on the frame, and includes at least one pair of rollers arranged side by side in a horizontal plane and a motor driving at least one roller to rotate. The roller surface has an elastic layer, and a feeding channel for the quartz raw material to pass through is formed between the two rollers. The width of the corresponding feeding channel before and after the elastic layer is deformed is counted as the minimum width and the maximum width respectively, and the diameter of the quartz raw material is between the maximum width and the minimum width;

[0007] A guide frame is installed on the frame, and includes a plurality of horizontally arranged guide plates, the plurality of guide plates are spaced apart above the rolling mechanism, and at least one row of guide holes is arranged on the guide plates corresponding to each quartz raw material to be unloaded, the corresponding guide holes on each guide plate are coaxial, and the guide holes and the unloading channel are located in the same vertical plane;

[0008] A melting device is installed on the frame and includes flame injection ports arranged in one-to-one correspondence with each guide hole;

[0009] The motor drives the roller shaft to rotate and drives the quartz raw material clamped at the material discharge channel to be sent downward so that the quartz raw material gradually passes through the corresponding flame injection port.

[0010] Furthermore, the elastic layer is a flexible rubber layer.

[0011] Furthermore, the elastic layer has straight knurling on its surface. The straight knurling can further increase the friction between the elastic layer and the quartz raw material.

[0012] Furthermore, the rollers include two pairs, the two pairs of rollers are arranged side by side in the same horizontal plane, the melting device is arranged below the middle two rollers of the two pairs of rollers, the melting device has two rows of flame jets spraying towards the left and right respectively to heat the two rows of quartz raw materials sent by the two pairs of rollers respectively, and two rows of guide holes are correspondingly arranged on the guide plate. The two pairs of rollers are arranged side by side not only makes the overall structure compact, but also significantly improves the processing efficiency.

[0013] Furthermore, each roller shaft is provided with a gear at one end close to the motor, and the gears are meshed and driven in sequence, and the motor drives one of the gears to rotate through the output shaft. The setting of the gears can drive multiple roller shafts to rotate through one motor, and can also ensure the synchronous rotation of the roller shafts.

[0014] Furthermore, the output shaft of the motor includes two sections, which are connected by a coupling. The arrangement of the coupling can play a certain buffering role in compensating for installation tolerance.

[0015] Furthermore, a bottom precision guide positioning plate is provided between the rolling mechanism and the melting device, and guide positioning holes are coaxially provided on the bottom precision guide positioning plate in one-to-one correspondence with the guide holes.

[0016] The beneficial effects of the present invention are as follows: when the quartz fiber melting vertical feeding device of the present invention is used, each row of quartz raw materials is inserted into the corresponding guide holes of the corresponding guide plates through a special tooling, until the lower end of the quartz raw materials is loaded into the feeding channel of the roller shaft, and the motor and the melting device are started in sequence. The motor drives the roller shaft to rotate, and the roller shaft rotates to clamp and feed the quartz raw materials downward by utilizing the friction between the elastic layer on the surface of the roller shaft and the quartz raw materials. Due to the guiding effect of the multiple guide plates arranged at intervals, each quartz raw material is in a completely horizontal state when entering the feeding channel, and due to the clamping effect of the elastic layer, the quartz raw materials are in the feeding channel. During the downward movement, the quartz raw materials are always positioned by the elastic layer to ensure that the quartz raw materials will not be misplaced. When they continue to descend, they can accurately enter the guide positioning holes of the bottom precision guide positioning plate, and then accurately pass through the flame injection ports of the melting device, ensuring that the quartz raw materials will not be misplaced during the entire feeding process, ensuring the processing quality; when the upper end of the quartz raw materials leaves the rolling mechanism, the operator can load the next batch of quartz raw materials according to the above steps, ensuring that the quartz raw materials are basically in a continuous and uninterrupted state during the entire processing process, which not only greatly improves the work efficiency, but also does not cause fuel waste in the melting device.

In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0024] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0025] An embodiment of the vertical feeding device for melting quartz fiber of the present invention is as follows: Figure 1-2As shown, the vertical feeding device for melting quartz fiber includes a frame 1, a rolling mechanism, a guide frame, a melting device 4 and a bottom precision guide positioning plate 5.

[0026] The frame 1 includes a fixed frame body composed of vertical rods and horizontal plates, which can be connected by welding or bolts.

[0027] The rolling mechanism is mounted on the frame 1 and includes at least one pair of rollers 21 arranged side by side in a horizontal plane and a motor 25 for driving at least one roller 21 to rotate. Figure 3 As shown, in this embodiment, there are two pairs of rollers 21 with a total of four rollers. In other embodiments, only one pair of rollers can be set. Correspondingly, the melting device only needs to be provided with one row of flame jets. In this embodiment, the two pairs of rollers 21 are arranged side by side in the same horizontal plane, and the melting device 4 is arranged below the middle two rollers of the two pairs of rollers 21. The melting device 4 has two rows of flame jets 41 spraying toward the left and right respectively to heat the two rows of quartz raw materials 7 sent down by the two pairs of rollers 21, and two rows of guide holes are correspondingly arranged on the guide plate 31. The aperture of the guide hole is 0.3-1mm larger than the diameter of the quartz raw material 7. It ensures that the positioning of the quartz raw material 7 is accurate enough while ensuring convenient material feeding. The two pairs of rollers 21 are arranged side by side, which not only makes the overall structure compact, but also significantly improves the processing efficiency. The surface of the roller 21 has an elastic layer 211, which is a flexible rubber layer, processed by rubber coating, and the surface of the elastic layer has straight knurling. The setting of straight knurling can further improve the friction between the elastic layer 211 and the quartz raw material 7. A feeding channel for the quartz raw material 7 to pass through is formed between the two rollers 21. The widths of the feeding channels corresponding to the deformation of the elastic layer before and after are respectively counted as the minimum width and the maximum width. The diameter of the quartz raw material 7 is between the maximum width and the minimum width so that it can be inserted into the feeding channel and can be clamped by the elastic layer. Gears 22 are respectively installed at one end of each roller 21 close to the motor 25. Each gear 22 is meshed and driven in sequence. The motor 25 drives one of the gears 22 to rotate through the output shaft 24. The setting of the gear 22 can drive multiple rollers 21 to rotate through one motor 25, and on the other hand, it also ensures the synchronous rotation of the rollers 21. A bottom precision guide positioning plate 5 is also arranged between the rolling mechanism and the melting device 4, and a guide positioning hole is coaxially arranged on the bottom precision guide positioning plate 5 corresponding to the guide hole.

[0028] The guide frame is installed on the frame 1, and includes a plurality of horizontally arranged guide plates 31. In this embodiment, three guide plates 31 are arranged in sequence, and the plurality of guide plates 31 are arranged at intervals above the rolling mechanism. At least one row of guide holes is arranged on the guide plates 31 corresponding to each quartz raw material 7 to be unloaded, and the corresponding guide holes on each guide plate 31 are coaxial, and the guide holes and the unloading channel are located in the same vertical plane.

[0029] The melting device 4 is mounted on the frame 1 and includes flame injection ports 41 arranged in one-to-one correspondence with the guide holes. The melting device 4 is prior art and will not be described in detail.

[0030] The motor 25 drives the roller shaft 21 to rotate and drives the quartz raw material 7 clamped at the material discharge channel to be sent downward so that the quartz raw material 7 gradually passes through the corresponding flame injection port 41 .

[0031] The output shaft 24 of the motor 25 includes two sections, which are connected by a coupling 23. The arrangement of the coupling 23 can play a certain buffering role in compensating for installation tolerance.

[0032] When the quartz fiber melting vertical feeding device of the present invention is used, a row of quartz raw materials 7 are inserted into the corresponding guide holes of the corresponding guide plates 31 through a special tool until the lower end of the quartz raw material 7 is inserted into the feeding channel of the roller 21, and the motor 25 and the melting device 4 are started in sequence. The motor 25 drives the roller 21 to rotate. The roller 21 rotates and utilizes the friction between the elastic layer 211 on the surface of the roller 21 and the quartz raw material 7 to clamp and feed the quartz raw material 7 downward. Due to the guiding effect of the multiple guide plates 31 arranged at intervals, each quartz raw material 7 is in a completely horizontal state when entering the feeding channel, and due to the clamping effect of the elastic layer, each quartz raw material 7 is in a completely horizontal state when entering the feeding channel. The material discharge channel is always positioned by the elastic layer during the downward movement, ensuring that the quartz raw materials 7 will not be misplaced. When continuing to descend further, they can accurately enter the guide positioning holes of the bottom precision guide positioning plate 5, and then accurately pass through the flame injection ports 41 of the melting device 4, ensuring that the quartz raw materials 7 will not be misplaced during the entire material discharge process, ensuring the processing quality; when the upper end of the quartz raw material 7 leaves the rolling mechanism, the operator can insert the next batch of quartz raw materials 7 according to the above steps, ensuring that the quartz raw materials 7 are basically in a continuous and uninterrupted state during the entire processing process, which not only greatly improves the work efficiency, but also does not cause fuel waste of the melting device 4.
