This invention can drive the fan blades to reciprocate left and right, thereby blowing off residual chips on the cutting equipment and effectively recovering and collecting the chips. The inventors discovered the following problems with the existing technology during the development of this invention:
[0004] The existing milling oil needs to be reused during the milling process. However, for some metal materials that cannot be magnetically attracted, some of the milled metal wires will be brought back into the milling oil recycling bin, causing the metal scrap wires to accumulate in the milling oil and affecting the material bar during the milling process.
[0005] Therefore, an anti-winding structure for a Swiss-type screw conveyor is proposed to address the above problems. Utility Model Content
[0006] In order to overcome the above-mentioned defects of the prior art, this utility model provides an anti-winding structure for a Swiss-type screw conveyor to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution: an anti-winding structure for a spiral conveyor with chip removal, comprising a spiral body and a chip removal mechanism. A feeding platform is provided on the side of the spiral body, and a chip removal mechanism is provided below the feeding platform. The chip removal mechanism includes a spiral chip removal drive unit and a reverse blade collecting assembly. A reverse blade collecting assembly is provided on the side of the spiral chip removal drive unit, and a fixed base is installed below the spiral body with bolts.
[0008] Preferably, the spiral chip removal drive unit includes a support base, a drive motor, and a fixing collar. The drive motor is bolted to the top of the support base, and the output end of the drive motor is keyed to the fixing collar. The spiral chip removal drive unit and the reverse blade collection assembly are connected to each other by the fixing collar to form a detachable structure.
[0009] Preferably, the reverse blade collecting assembly includes a limiting plate, a positioning plate, a sleeve, and a liquid inlet. The limiting plate is provided with a positioning plate on the side away from the spiral chip removal drive unit, and a sleeve is provided between the two sets of positioning plates. The sleeve is located between the two sets of positioning plates and has a liquid inlet.
[0010] Preferably, the reverse blade collecting assembly further includes an oil collection box, a slag outlet, an oil outlet, a filter screen, a screw, and a reverse scraper. The oil collection box is located above the liquid inlet, and the positioning plate and the oil collection box are connected by bolts to form a detachable structure. An oil outlet is located on the side of the sleeve away from the fixing collar. The screw is placed inside the sleeve, and the screw and the drive motor are connected by a coupling to form a detachable structure. A reverse scraper is provided on the inner diameter surface of the sleeve along the opposite direction of the screw thread, and the reverse scraper and the screw bolt are interleaved.
[0011] Preferably, a material bar is placed at the material feeding end of the material feeding platform, and a feeding channel is provided on the side of the material bar.

[0013] The technical effects and advantages of this utility model are as follows:
[0014] 1. Compared with the prior art, this anti-winding structure for a Swiss-type screw conveyor for chip removal utilizes a core component sleeve. Inside the sleeve, reverse scrapers with threads opposite to the screw and staggered distribution are installed. The drive motor connects to the screw via a coupling. When the screw rotates, the screw thread contacts the reverse scrapers inside the sleeve, squeezing the metal wires brought by the screw and separating them from the screw. The gradually changing reverse scrapers inside the sleeve compress the metal wires, reducing the pressure during separation for easier detachment. A liquid inlet at the top of the sleeve receives the injection of milling fluid, allowing the milling oil to enter the sleeve's interior.
[0015] 2. Compared with existing technologies, this anti-winding structure of the Swiss-type screw conveyor for chip removal utilizes the synergistic effect of a reverse scraper and a screw. The reverse scraper is positioned in the opposite direction to the screw. When the screw rotates and conveys chips, the scraper moves in the opposite direction to break up the tangled metal wires and simultaneously squeezes the metal wires. It generates mechanical shearing force, especially for long, rolled chips, preventing the screw shaft from clogging at the source. The staggered structural layout of the scraper and screw bolts forms a multi-angle cutting surface, enhancing the breaking effect on sticky chips and avoiding the twisted entanglement problem that occurs in traditional screw conveyors.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Example 1
[0027] As attached Figures 1 to 8 The above describes an anti-winding structure for a spiral conveyor with a chip removal mechanism, which includes a spiral body 1 and a chip removal mechanism 3. A feeding platform 2 is provided on the side of the spiral body 1, and the chip removal mechanism 3 is provided below the feeding platform 2. The chip removal mechanism 3 includes a spiral chip removal drive unit 11 and a reverse knife collection assembly 15. The reverse knife collection assembly 15 is provided on the side of the spiral chip removal drive unit 11, and a fixed base 4 is installed on the bottom of the spiral body 1 by bolts.
[0028] Specifically, the reverse scraper 20 works in conjunction with the screw 19. The reverse scraper 20 is set in the opposite direction to the screw 19. When the screw 19 rotates and conveys chips, the scraper moves in the opposite direction to break the tangled metal wires and squeeze the metal wires. It forms mechanical shearing force, especially for long rolled chips, to prevent the screw shaft from clogging at the source. The staggered structure layout of the reverse scraper 20 and the screw 19 is arranged in a staggered manner to form a multi-angle cutting surface, which enhances the crushing effect on sticky chips and avoids the problem of twisted entanglement that occurs in traditional screw conveyors.
[0029] When the sliding headstock 1 processes the bar 201 to be milled, the milling oil cools the bar 201 in the processing area. The spraying of the milling oil also coats up and carries away the metal scrap or wires at the milling point, thus cooling the milling area and removing milling waste to avoid affecting the milling process. Since the milling oil needs to be reused during the milling process, some metal materials that cannot be magnetically attracted will cause some of the milled metal wires to be carried back into the milling oil recycling tank, resulting in the accumulation of metal scrap wires in the milling oil and affecting the bar 201 during the milling process. The chip removal mechanism 3, through the spiral chip removal drive unit 11, drives the screw 19 in the reverse scraper collection assembly 15, which contacts the reverse scraper 20 in the sleeve 1503 through the bolt, continuously collecting and discharging the metal scrap wires, thereby continuously reducing the metal scrap wire content in the milling oil and facilitating the use of the milling oil.
[0030] Example 2
[0031] Based on Example 1, the solution in the example will be further described in detail below with reference to the specific working method, such as... Figures 1 to 8As shown below, see details:
[0032] In a preferred embodiment, the spiral chip removal drive unit 11 includes a support base 12, a drive motor 13, and a fixing collar 14. The drive motor 13 is bolted to the top of the support base 12, and the output end of the drive motor 13 is keyed to the fixing collar 14. The spiral chip removal drive unit 11 and the reverse blade collection assembly 15 are detachable through the fixing collar 14. The drive motor 13 is mounted on the support base 12 and is specifically a stepper motor. The stepper motor enables the forward and reverse rotation of the screw 19. The fixing collar 14 allows for the inspection and replacement of the sleeve 1503 inside the reverse blade collection assembly 15, thereby facilitating the use of the reverse blade collection assembly 15.
[0033] In a preferred embodiment, the reverse blade collecting assembly 15 includes a limiting plate 1501, a positioning plate 1502, a sleeve 1503, and a liquid inlet 1504. The positioning plate 1502 is located on the side of the limiting plate 1501 away from the spiral chip removal drive unit 11. A sleeve 1503 is positioned between the two sets of positioning plates 1502, and the sleeve 1503 has a liquid inlet 1504 located between the two sets of positioning plates 1502. When using the core component sleeve 1503, because it contains a reverse scraper 20 whose thread direction is opposite to that of the screw 19, and which... The drive motor 13 is connected to the screw 19 via a coupling. When the screw 19 rotates, the thread of the screw 19 contacts the reverse scraper 20 inside the sleeve 1503, squeezing the metal wire brought by the screw 19 and separating the metal wire from the screw 19. The gradually changing reverse scraper 20 inside the sleeve 1503 compresses the metal wire and reduces the degree of pressure when it is separated, thus facilitating separation. The liquid inlet 1504 provided at the top of the sleeve 1503 is used to receive the injection of milling fluid, and the milling oil enters the interior of the sleeve 1503.
[0034] In a preferred embodiment, the reverse blade collecting assembly 15 further includes an oil collection box 16, a slag outlet 17, an oil outlet 18, a filter screen 1801, a screw 19, and a reverse scraper 20. The oil collection box 16 is positioned above the liquid inlet 1504, and the positioning plate 1502 and the oil collection box 16 are connected by bolts to form a detachable structure. An oil outlet 18 is located on the side of the sleeve 1503 away from the fixing collar 14. The screw 19 is placed inside the sleeve 1503, and the screw 19 and the drive motor 13 are connected by a coupling to form a detachable structure. A reverse scraper 20 is positioned on the inner diameter surface of the sleeve 1503 in the opposite direction to the screw 19 thread. The reverse scraper 20 and the screw 19 bolts are interleaved, and the oil flows out through the oil outlet 18 at the bottom of the sleeve 1503. The metal wire remains on the filter screen 1801 above the oil outlet 18 and is then removed by the screw 19. 9. The metal wires are removed, thus preventing the filter screen 1801 from being clogged by the filter screen 1801. The oil collection box 16 separates oil and debris through the filter screen 1801, realizing the recycling of coolant. When the metal wires are removed by the screw 19, the screw 19 drives the metal wires to be squeezed against the cylinder wall of the sleeve 1503. During the continued squeezing process, the metal wires between the threads of the screw 19 are contacted by the reverse scraper 20 inside the sleeve 1503. At this time, the metal wires are squeezed by both the threads of the screw 19 and the cylinder wall of the sleeve 1503. The reverse scraper 20 squeezes and removes the metal wires in the threads of the screw 19. Since the reverse scraper 20 has a gradually changing length structure, the metal wires are continuously squeezed, thereby squeezing the milling oil wrapped on the outer surface of the metal wires and continuing to drive the metal wires to move, thus completing the process of driving and removing the metal wires.
[0035] In a preferred embodiment, a material bar 201 is placed at the material feeding end of the material feeding platform 2, and a feeding channel 202 is provided on the side of the material bar 201.
[0036] In a preferred embodiment, a clamping frame 6 is provided on the inner wall side of the sliding headstock body 1, and a horizontal milling cutter holder 7 is provided on the side of the clamping frame 6 away from the feed channel 202. A slide rail 8 is provided below the horizontal milling cutter holder 7, and a circulation collection chamber 9 is provided below the slide rail 8. A collection port 10 is reserved in the circulation collection chamber 9 directly below the clamping frame 6. A cooling oil spray pipe 5 is provided above the clamping frame 6, and the center of the collection port 10 is placed in the oil collection box 16. When the milling oil is cooled, the milling oil falls into the oil collection box 16 in the collection port 10.
[0037] The working process of this utility model is as follows: First, the spiral chip removal drive unit 11 mounts the drive motor 13 on the support base 12. The drive motor 13 is specifically a stepper motor, which realizes the forward and reverse rotation of the screw 19. Furthermore, through the fixing collar 14, the sleeve 1503 inside the reverse blade collecting assembly 15 can be inspected and replaced, thus facilitating the use of the reverse blade collecting assembly 15. When using the core component sleeve 1503, because it contains a reverse scraper 20 whose thread direction is opposite to that of the screw 19... The screws are arranged in a staggered pattern. The drive motor 13 is connected to the screw 19 via a coupling. When the screw 19 rotates, its thread contacts the reverse scraper 20 inside the sleeve 1503, squeezing the metal wire brought by the screw 19 and separating it from the screw 19. The gradually changing reverse scraper 20 inside the sleeve 1503 applies pressure to the metal wire and reduces the pressure during separation, thus facilitating separation. The liquid inlet 1504 at the top of the sleeve 1503 is used to receive the injection of milling fluid and to mill the wire. Oil enters the interior of the sleeve 1503 and flows out through the oil outlet 18 at the bottom of the sleeve 1503. The metal wire remains on the filter screen 1801 above the oil outlet 18 and is carried away by the screw 19, thus preventing the filter screen 1801 from being blocked by the metal wire. The oil collection box 16 separates oil and debris through the filter screen 1801, realizing the recycling of coolant. When the metal wire is carried away by the screw 19, the screw 19 drives the metal wire to squeeze against the cylinder wall of the sleeve 1503. During the continued squeezing process, the metal wire between the threads of the screw 19 is subjected to pressure from the sleeve 1503. The reverse scraper 20 inside 503 comes into contact with the metal wire, which is simultaneously squeezed by the thread of the screw 19 and the cylinder wall of the sleeve 1503. The reverse scraper 20 squeezes the metal wire in the thread of the screw 19 and pulls it away. Since the reverse scraper 20 has a gradually changing length structure, the metal wire is continuously squeezed, thereby squeezing the milling oil wrapped on the outer surface of the metal wire and continuing to drive the metal wire to move, thus completing the driving and pulling of the metal wire away. The above is the working principle of the anti-winding structure of the Swiss-type chip conveyor.
