[0027] Embodiment 2:

[0028] The difference between the above embodiment and this embodiment is that: Figures 1 to 9 As shown, a side plate 2011 is installed on the top of the back plate 104, and a reinforcing rib 2012 is installed on the bottom of the side plate 2011. The reinforcing rib 2012 is triangular, and the other side of the reinforcing rib 2012 is connected to the back plate 104, and the bottom of the side plate 2011 is connected to the housing of the hydraulic push rod 201.

[0029] like Figures 1 to 9 As shown, in a specific embodiment, a slide rail 2031 is installed on the first guide ring 203, and the slide rail 2031 is an annular slide rail, and the slide rail 2031 and the end of the synchronous bracket 202 are slidingly connected, a slide plate 2032 is installed at the bottom of the first guide ring 203, and a second guide ring 2033 is installed at the end of the slide plate 2032, the second guide ring 2033 and the cutting motor 204 are slidingly connected, the synchronous bracket 202 can slide on the slide rail 2031, and the rotation of the second guide ring 2033 and the cutting motor 204 can synchronously drive the first guide ring 203 to rotate.

[0030] like Figures 1 to 9 As shown, further, a fixing seat 205 is installed on the cutting motor 204, a guide rod 2051 is installed on the fixing seat 205, the guide rod 2051 movably penetrates the slide plate 2032, a return spring 2052 is sleeved on the guide rod 2051, one end of the return spring 2052 is clamped on the fixing seat 205, and the other end of the return spring 2052 is clamped on the slide plate 2032. During the movement of the cutting motor 204, the position of the fixing seat 205 on the cutting motor 204 changes, the guide rod 2051 slides in the slide plate 2032, and the return spring 2052 is squeezed, and the return spring 2052 is used to facilitate the subsequent return operation.

[0031] Embodiment 3:

[0032] The difference between the above embodiment and this embodiment is that: Figures 1 to 9 As shown, a synchronous shaft 2041 is installed at the output end of the cutting motor 204, and the end of the synchronous shaft 2041 is connected to the cutting blade 2042. A positioning seat 206 is installed on the side wall of the cutting motor 204, and a slide bar 2061 is rotatably installed on the positioning seat 206, and the end of the slide bar 2061 is chamfered. When the cutting motor 204 is started, the synchronous shaft 2041 is driven to rotate, and the synchronous shaft 2041 drives the cutting blade 2042 to rotate at a high speed, thereby achieving the purpose of cutting.

[0033] like Figures 1 to 9As shown, in a specific embodiment, a through hole 3012 is provided inside the positioning ring 301, and the cutting motor 204 is placed on the side wall of the through hole 3012. The through hole 3012 corresponds vertically to the outlet of the shaping cover 102, and a vertical rod 3011 is installed on the side wall of the positioning ring 301. A clamping shaft 3031 is installed on the baffle 303, and the clamping shaft 3031 is rotatably installed on the side wall of the feed chute 3022. A torsion spring 3032 is sleeved on the clamping shaft 3031, and one end of the torsion spring 3032 is clamped on the side wall of the feed chute 3022, and the other end of the torsion spring 3032 is clamped on the baffle 303. The length of the baffle 303 is greater than the width of the reset chute 3024, and the reset chute 3024 is in a vertical state. When the hydraulic push rod 201 is reset upward in the later stage, the slide bar 2061 slides upward along the reset slide groove 3024, which can push the baffle 303 to rotate. When the slide bar 2061 moves to above the baffle 303, the baffle 303 is reset by the torsion spring 3032, and the inclined baffle 303 facilitates the subsequent movement of the slide bar 2061 into the feed slide groove 3022.

[0034] The implementation principle of a special-shaped tube production process for purifying high-purity quartz sand in this embodiment is as follows: When it is necessary to produce special-shaped tubes normally, the operator can inject purified molten quartz sand into the feed tube 1011 through the injection structure, wherein the injection structure is a prior art, so it is not shown in the figure again. The molten quartz sand can eventually fill the entire feed tube 101 chamber, and finally fall into the inner cavity 1024 of the shaping cover 102. Through the guiding effect of the shaping cover 102 and the plastic core 103, the molten quartz sand can only flow out from the gap between the shaping cover 102 and the plastic core 103, and then a tubular quartz tube can be obtained. Moreover, through the cooperation of the groove and the plastic groove, the tubular quartz tube can obtain different contours, and then special-shaped quartz tubes can be produced. The produced quartz tube can continue to slide down with the extrusion operation. When the specified length is reached, the cutting operation is completed by the extrusion cutting unit 200 and the shift cutting unit 300.

[0035] When the cutting operation is required, the operator first needs to close the feed pipe 1011 through the valve 1012, and when closing, the operator needs to start the hydraulic push rod 201, and the hydraulic push rod 201 drives the pressure plate 2013 to move downward, and the pressure plate 2013 can press the raw material inside the feed barrel 101, so that the raw material can move downward along the outlet of the shaping cover 102, and at this time, it is necessary to control the thickness of the raw material discharged from the feed barrel per unit time and the increased length of the special-shaped quartz tube to be the same, to ensure that the pressure plate and the quartz tube move downward synchronously.

[0036] During the downward movement of the pressure plate 2013, the synchronous bracket 202 on the side wall drives the first guide ring 203 and the second guide ring 2033 to move downward, and the cutting motor 204 at the bottom of the second guide ring 2033 moves downward synchronously, ensuring that the cutting blade 2042 at the end of the cutting motor 204 moves synchronously with the quartz tube to ensure that the cutting position does not change, and the cutting motor 204 starts to drive the cutting blade 2042 to rotate.

[0037] During the downward movement of the cutting motor 204, the slide bar 2061 on the side wall of the cutting motor 204 slides inside the combined slide groove 302. The slide bar 2061 first slides in the feed slide groove 3022, and finally moves along the slope 3023 to the initial end of the transposition slide groove 3021. In this process, due to the depth of the combined slide groove 302, the slide bar 2061 moves outward as a whole, driving the cutting blade 2042 to move into the extruded quartz tube, thereby achieving the purpose of cutting.

[0038] During the movement of the cutting motor 204, the position of the fixing seat 205 on the cutting motor 204 changes, and the guide rod 2051 slides in the slide plate 2032 to squeeze the reset spring 2052, thereby facilitating the subsequent reset operation through the reset spring 2052.

[0039] Then the slide bar 2061 slides along the transposition slot 3021, and the spiral shape drives the slide bar 2061 to rotate around the transposition slot 3021 as a whole, and finally drives the cutting motor 204 to rotate, so that the cutting blade 2042 rotates on the quartz tube, achieving the purpose of circular cutting.

[0040] Finally, the slide bar 2061 can move to the reset slot 3024. At this time, the position of the cutting blade 2042 is reset by the reset spring 2052, so that the cutting blade 2042 and the quartz tube are separated. When the hydraulic push rod 201 is reset in the later stage, the slide bar 2061 slides upward along the reset slot 3024, which can push the baffle 303 to rotate. When the slide bar 2061 moves to the top of the baffle 303, the baffle 303 is reset by the torsion spring 3032, and the inclined baffle 303 facilitates the subsequent movement of the slide bar 2061 to the feed slot 3022.
