DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0026] The present invention provides a cable sheath coating processing device, such as Figures 1 to 7As shown, it includes a bottom plate 1, an extrusion assembly 2 is arranged on the top of the bottom plate 1, and the extrusion assembly 2 is a component on the extruder in the prior art that can extrude the molten plastic melt to combine it with the cable, a cooling water pool 3 is arranged on one side of the extrusion assembly 2, and a shell 4 connected to the extrusion assembly 2 is arranged on the top of the extrusion assembly 2, and an annular net 6 is rotatably arranged inside the shell 4, and ring plates 5 are fixedly installed on both sides of the annular net 6, and openings are equidistantly arranged around the outer side of the annular net 6, and baffles 7 are arranged in the openings, and grooves connected to the openings are arranged on the outer side of the ring plate 5, and magnets 9 are arranged in the grooves, and the outer side of the baffle 7 is symmetrically fixed. An iron block 8 that cooperates with the magnet 9 is fixedly installed, a driving assembly for driving the baffle 7 to move away from the center of the shell 4 is provided on the top of the shell 4, a rotating assembly for driving the ring plate 5 to rotate is provided on the outside of the shell 4, a circular ring 13 is fixedly installed on the inner side of the ring plate 5, the circular ring 13 is fitted with the outer side of the baffle 7, a melting device 24 for melting plastic particles is fixedly installed on the inner wall of one side of the shell 4, a scraper 10 that fits with the inner wall of the annular net 6 is provided inside the shell 4 and directly above the melting device 24, and the melting device 24 is a device that can melt plastic particles in the prior art.

[0027] When in use, plastic particles are added to the melting device 24. The plastic particles are melted and flow downward in a molten state through the annular net 6 to filter out the particles that are not completely melted, and then enter the extrusion component 2. The cable passing through the extrusion component 2 can be combined with the molten plastic to cover the cable sheath. The cable covered with the sheath then enters the cooling water pool 3 and is cooled by the cooling water in the cooling water pool 3. The subsequent winding process is then carried out. The ring plate 5 is driven by the rotating component to move with the annular net 6 and the baffle 7, so that the particles filtered and retained on the inner wall of the annular net 6 are moved. The setting of the baffle 7 can prevent the particles from falling during the movement, and ensure that the particles can move with the baffle 7 and the annular net 6. When the baffle 7 moves to the top of the melting device 24, the driving component drives the baffle 7 to move in a direction away from the center of the shell 4, so that one end of the baffle 7 can eventually be flush with the inner wall of the annular net 6, thereby The particles attached to the surface of the baffle 7 are scraped off, and subsequently with the movement of the annular net 6, the scraper 10 is used to scrape off the particles on the inner wall of the annular net 6, so that these particles that are not completely melted fall into the melting device 24 for melting again. The fully melted particles are in a molten state, and enter the extrusion component 2 after being filtered by the annular net 6. When the baffle 7 moves to the top of the melting device 24 about to leave, the driving component cancels the drive of the baffle 7. Under the action of gravity and the suction of the iron block 8 and the magnet 9, the baffle 7 is reset, and the iron block 8 and the magnet 9 are adsorbed and fixed to keep the baffle 7 in a fixed state. The above operation can be repeated later, so that the melt can be continuously filtered and the particles that are not completely melted can be brought back into the melting device 24 for melting again, so that it can be ensured that the melt entering the extrusion component 2 does not contain particles, thereby ensuring that the cable sheath does not contain particles, thereby improving the coating quality of the cable sheath.

[0028] like Figure 3 As shown, the driving assembly includes a connecting plate 11 fixedly connected to the top of the shell 4, and an arc-shaped magnetic piece 12 is fixedly connected to the top of the connecting plate 11. The baffle 7 is made of iron. The suction force of the arc-shaped magnetic piece 12 is sufficient to overcome the suction force of the magnet 9 and move the baffle 7 and the iron block 8 away from the center of the shell 4 until they collide with the top wall of the arc-shaped magnetic piece 12.

[0029] When the baffle 7 moves to the arc-shaped magnetic sheet 12, the baffle 7 is located above the melting device 24 and is attracted by the arc-shaped magnetic sheet 12, so that the baffle 7 moves away from the center of the shell 4 with the iron block 8 to overcome the suction force of the magnet 9, so that the particles attached to the surface are scraped off, and finally the baffle 7 contacts the top wall of the arc-shaped magnetic sheet 12. Then, as the annular net 6 rotates, the baffle 7 contacts the arc-shaped magnetic sheet 12 and then slides relatively on its surface. When the baffle 7 leaves the arc-shaped magnetic sheet 12, the suction force of the arc-shaped magnetic sheet 12 on the baffle 7 disappears. Under the action of gravity and the suction force of the iron block 8 and the magnet 9, the baffle 7 is reset, and the iron block 8 and the magnet 9 are adsorbed and fixed.

[0030] like Figure 2 As shown, the rotating assembly includes teeth 14 equidistantly arranged around the inner side of a ring plate 5 , a motor 15 is fixedly mounted on the outer side of the housing 4 , and an output shaft of the motor 15 is fixedly connected to a gear 16 that cooperates with the teeth 14 .

[0031] The motor 15 is started to make its output shaft rotate with the gear 16 , and the teeth 14 cooperate with the ring plate 5 and the ring net 6 to rotate, so as to drive the ring plate 5 .

[0032] like Figure 6 to Figure 7 As shown, a feed plate 17 is fixedly installed on the side of the shell 4 away from the motor 15. The top of the feed plate 17 is fixedly connected to the scraper 10 through an L-shaped plate 18. A rectangular rod 19 is slidably inserted into the top of the L-shaped plate 18. A racket bar 20 is fixedly installed on the bottom of the rectangular rod 19. The racket bar 20 is in contact with the bottom of the scraper 10. A circulation component for driving the rectangular rod 19 to reciprocate up and down is provided on the L-shaped plate 18.

[0033] When the annular net 6 rotates, the circular ring 13 moves accordingly, and the circulation component drives the rectangular rod 19 to move with the beater rod 20, so that the beater rod 20 continuously beats the scraper 10 to vibrate it, thereby shaking the particles attached to its surface to the melting device 24 below, avoiding the particles from sticking to the scraper 10 for too long and solidifying, which affects the normal use of the scraper 10 later.

[0034] like Figure 6 to Figure 7 As shown, the circulation assembly includes a wedge block 21 fixedly connected to the top of a rectangular rod 19, a spring 22 is sleeved on the outside of the rectangular rod 19, and a pressure plate 23 cooperating with the wedge block 21 is fixedly installed equidistantly around the inner side of the ring 13.

[0035] The circular ring 13 rotates with the pressure plate 23, and the pressure plate 23 contacts the inclined surface of the wedge block 21 to squeeze the wedge block 21, causing it to descend with the rectangular rod 19 and the racket 20. At the same time, the wedge block 21 compresses the spring 22 to deform it and generate a force. When the pressure plate 23 separates from the wedge block 21, the spring 22 releases the force to move the wedge block 21, the rectangular rod 19 and the racket 20 upward, causing the racket 20 to hit the bottom of the scraper 10, causing the scraper 10 to vibrate. As multiple pressure plates 23 are continuously contacted and separated from the wedge block 21, the scraper 10 can be continuously vibrated.

[0036] like Figure 3 As shown, when the baffle 7 contacts the top wall of the arc-shaped magnetic sheet 12 , the end of the baffle 7 close to the center of the shell 4 is flush with the inner wall of the annular net 6 .

[0037] The baffle 7 will not hinder the scraper 10 from scraping the particles on the inner wall of the annular net 6.

[0038] like Figure 2 As shown, the torque of the motor 15 is sufficient to drive the baffle 7 to slide along the inner wall surface of the arc-shaped magnetic sheet 12 after it contacts the arc-shaped magnetic sheet 12 .

[0039] After the baffle plate 7 and the arc-shaped magnetic sheet 12 are adsorbed, the motor 15 can still drive the ring plate 5, the ring net 6 and the baffle plate 7 to continue to move.

[0040] like Figure 3 As shown, when the baffle plate 7 contacts the arc-shaped magnetic sheet 12 , the baffle plate 7 is located above the melting device 24 .

[0041] The particles falling from the baffle 7 can enter the melting device 24 below to be fully melted.

[0042] Working principle: When in use, plastic particles are added to the melting device 24 through the feed plate 17. The plastic particles are melted and flow downward in a molten state through the annular net 6 to filter out the particles that are not completely melted, and then enter the extrusion component 2. The cable passing through the extrusion component 2 can be combined with the molten plastic to coat the cable sheath. The cable coated with the sheath then enters the cooling water pool 3 and is cooled by the cooling water in the cooling water pool 3. The subsequent winding process is then carried out. The motor 15 is started so that its output shaft rotates with the gear 16, and the teeth 14 rotate with the ring plate 5 and the annular net 6. The baffle 7 moves accordingly, so that the particles filtered and left on the inner wall of the annular net 6 move. The setting of the baffle 7 can prevent movement. During the process, the particles fall, ensuring that the particles can move with the baffle 7 and the annular net 6. When the baffle 7 moves to the top of the melting device 24, the baffle 7 moves to the arc-shaped magnetic sheet 12. At this time, the baffle 7 is located above the melting device 24. At this time, it is attracted by the arc-shaped magnetic sheet 12, so that the baffle 7 carries the iron block 8 to overcome the suction force of the magnet 9 and moves away from the center of the shell 4, so that the particles attached to the surface are scraped off. Finally, the baffle 7 conflicts with the top wall of the arc-shaped magnetic sheet 12. Then, as the annular net 6 rotates, the baffle 7 conflicts with the arc-shaped magnetic sheet 12 and slides relatively on its surface. With the movement of the annular net 6, the scraper 10 scrapes off the particles on the inner wall of the annular net 6, so that this part of the particles that are not completely melted falls into the melting device 24 for melting again, and is fully melted. The melted particles are in a molten state and enter the extrusion assembly 2 after being filtered by the annular mesh 6. When the baffle 7 moves to the top of the melting device 24, the baffle 7 leaves the arc-shaped magnetic sheet 12. At this time, the suction of the arc-shaped magnetic sheet 12 on the baffle 7 disappears. Under the action of gravity and the suction of the iron block 8 and the magnet 9, the baffle 7 is reset, and the iron block 8 and the magnet 9 are adsorbed and fixed to keep the baffle 7 in a fixed state. The above operation can be repeated later, so that the melt can be continuously filtered and the particles that are not completely melted can be brought back into the melting device 24 for melting again, so that the melt entering the extrusion assembly 2 can be guaranteed to contain no particles, thereby ensuring that the cable sheath does not contain particles, thereby improving the coating quality of the cable sheath; the annular plate 5 is brought As the ring 13 rotates, the ring 13 rotates with the pressure plate 23. The pressure plate 23 contacts the inclined surface of the wedge block 21 and squeezes the wedge block 21 to make it descend with the rectangular rod 19 and the racket 20. At the same time, the wedge block 21 compresses the spring 22 to deform it and generate a force. When the pressure plate 23 separates from the wedge block 21, the spring 22 releases the force to make the wedge block 21, the rectangular rod 19 and the racket 20 rise, so that the racket 20 hits the bottom of the scraper 10, and the scraper 10 vibrates. As multiple pressure plates 23 are continuously separated from the wedge block 21, the scraper 10 can be continuously vibrated, thereby shaking the particles attached to its surface into the melting device 24 below, so as to prevent the particles from sticking to the scraper 10 for too long and solidifying, affecting the normal use of the scraper 10 later.

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
