[0032] like Figures 1 to 7 As shown, a continuous feeding device for forming fluorine-lined steel parts provided in an embodiment of the present invention includes a frame 100 and a feeding pipe 300.

[0033] A feeding bin 110 is fixedly connected to the frame 100, a feeding port is opened at the lower end of the feeding bin 110, and powder is filled in the feeding bin 110; a first support assembly 120, a second support assembly 140, a rotation drive assembly and a heating assembly are installed on the frame 100, the first support assembly 120 is located on one side of the feeding bin 110, the first support assembly 120 is used to support the steel pipe 200, and the steel pipe 200 can rotate around its own axis on the first support assembly 120; the rotation drive assembly is used to drive the steel pipe 200 to rotate around its own axis; the heating assembly is arranged below the steel pipe 200, and is used to heat the steel pipe 200; a recovery box is also installed on the bracket, and the recovery box is arranged below the feeding pipe 300.

[0034] The feeding tube 300 is axially movable and rotatably mounted on the second support assembly 140; the second support assembly 140 includes a support frame 141 and a support ring 142, the support ring 142 is coaxially arranged with the feeding tube 300, the support frame 141 is fixedly connected to the frame 100, and the support ring 142 is fixedly connected to the support frame 141; the feeding tube 300 is provided with a feeding port 310, the feeding port 310 extends along the axial direction of the feeding tube 300, and the feeding port is located directly above the feeding port 310; The feeding tube 300 is coaxial with the steel tube 200, and the feeding tube 300 can be inserted into the steel tube 200; the feeding tube 300 can be manually controlled to move axially and rotate circumferentially, and can also be driven by a driving mechanism; preferably, the end of the feeding tube 300 away from the steel tube 200 is connected to a driving mechanism, and the driving mechanism is used to drive the feeding tube 300 to rotate circumferentially and move axially, and the driving mechanism includes an axial driving assembly and a circumferential driving assembly, the axial driving assembly can be a cylinder, and the circumferential driving assembly can be a motor.

[0035] The rotation drive assembly includes a drive motor and a transmission wheel 130. The transmission wheel 130 is rotatably mounted on the frame 100. The axis of the transmission wheel 130 is parallel to the axis of the steel pipe 200. The drive motor is used to drive the transmission wheel 130 to rotate. The transmission wheel 130 and the steel pipe 200 are frictionally driven. After starting, the drive motor drives the transmission wheel 130 to rotate, and the transmission wheel 130 drives the steel pipe 200 to rotate.

[0036] When in use, fill powder into the feeding bin 110, place the steel pipe 200 on the first supporting assembly 120, start the heating assembly and the driving motor, the heating assembly increases the temperature of the steel pipe 200, the driving motor drives the transmission wheel 130 to rotate, and the transmission wheel 130 drives the steel pipe 200 to rotate around its own axis, so that the temperature of the steel pipe 200 is more uniform; when the temperature of the steel pipe 200 reaches a preset value, the feeding pipe 300 is driven to approach the steel pipe 200 at a uniform speed along the axial direction, and the powder in the feeding bin 110 passes through the feeding port and the feeding port 310 in turn and enters the feeding pipe 300. In the process of the feeding pipe 300 moving along the axial direction, the powder is stored in the feeding pipe 300, and each The amount of powder stored per unit length is equal; after the feeding tube 300 extends into the steel pipe 200 by a preset length, the feeding tube 300 stops moving axially, and drives the feeding tube 300 to rotate 180° around its own axis. In the projection of the vertical plane perpendicular to the axis direction of the feeding tube 300, the diameter of the feeding port is equal to the outer diameter of the feeding tube 300, so that when the feeding tube 300 rotates, the feeding port is blocked by the feeding tube 300, and no powder is added to the feeding tube 300, thereby avoiding waste; and the powder in the feeding tube 300 enters the steel pipe 200 through the feeding port 310, and the powder entering the steel pipe 200 is evenly sintered and formed on the inner wall of the steel pipe 200 as the steel pipe 200 rotates. When the feeding tube 300 pours the powder into the steel pipe 200, the recycling box collects the fallen powder to avoid waste. After a preset time, the feeding tube 300 is driven away from the steel tube 200 and the feeding tube 300 returns to its initial position.

[0037] When the next feeding is needed, the feeding pipe 300 is driven to rotate 180° around its own axis and then approaches the steel pipe 200 along the axis direction, and the above process is repeated to complete automatic filling and feeding. Compared with the prior art, the present invention can automatically complete filling and feeding, and can complete continuous feeding work, thereby improving the feeding efficiency, thereby improving the processing efficiency of steel lining fluorine parts, and the powder in the feeding pipe 300 is evenly distributed, thereby ensuring the uniform thickness of the lining in the steel pipe 200 and ensuring the processing quality of the steel lining fluorine parts.

[0038] In a further embodiment, a vibration assembly 400 is installed on the frame 100, and the vibration assembly 400 is located at the feeding port of the feeding bin 110; the vibration assembly 400 is used to knock the feeding bin 110 during the feeding process.

[0039] By continuously knocking the feeding bin 110, powder accumulation is prevented from clogging the feeding port, thereby making the process of powder entering the feeding pipe 300 from the feeding bin 110 smoother, and further making the powder in the feeding pipe 300 more evenly distributed, thereby ensuring the processing quality and efficiency of the steel fluorine-lined parts.

[0040] In a further embodiment, the feeding port 310 is wavy in shape; the vibration assembly 400 includes a fixing frame 410 , a sensing block 420 , a toggle rod 430 , two transmission members 440 and two knocking rods 450 .

[0041] The sensing block 420 is coaxially arranged inside the feeding tube 300. The sensing block 420 can be rotatably installed on the frame 100 around its own axis. A first boss 421 is fixedly connected to the sensing block 420. The first boss 421 passes through the feeding port 310 and extends out of the feeding tube 300. The diameter of the first boss 421 is equal to the width of the feeding port 310. When the feeding tube 300 moves axially relative to the sensing block 420, the sensing block 420 swings back and forth around its own axis within a preset range.

[0042] The toggle rod 430 is vertically arranged and rotatably mounted on the feeding bin 110, with the rotation axis being parallel to the axis of the feeding tube 300. A first torsion spring is installed between the toggle rod 430 and the feeding bin 110, and the first torsion spring keeps the toggle rod 430 in a vertical state.

[0043] The fixed frame 410 is fixedly connected to the frame 100, and the two transmission members 440 are rotatably connected to the fixed frame 410 and are respectively located on both sides of the toggle rod 430, and the rotation axis of the transmission member 440 is parallel to the axis of the feeding tube 300; the end of the transmission member 440 close to the toggle rod 430 is in contact with the toggle rod 430, and the end away from the toggle rod 430 is fixedly connected with a knocking rod 450, and the two knocking rods 450 are respectively located on both sides of the feeding bin 110, and the axis of the knocking rod 450 is parallel to the axis of the feeding tube 300; a second torsion spring is installed between the transmission member 440 and the fixed frame 410, and the second torsion spring has a tendency to keep the transmission member 440 in contact with the toggle rod 430.

[0044] When the feeding tube 300 moves along its own axis, the first protrusion 421 slides in the feeding port 310, thereby driving the sensing block 420 to swing back and forth around its own axis within a preset range. Figure 7As shown, when the sensing block 420 rotates clockwise, it pushes the toggle rod 430 to rotate counterclockwise, thereby prompting the transmission member 440 on the left to rotate clockwise, and the knocking rod 450 on the left moves away from the feeding bin 110. When the first protrusion 421 is out of contact with the toggle rod 430, the toggle rod 430 returns to its vertical state under the action of the first torsion spring, and the transmission member 440 on the left remains in contact with the toggle rod 430 under the action of the second torsion spring; thereafter, the sensing block 420 rotates counterclockwise, pushing the toggle rod 430 to rotate clockwise, thereby prompting the transmission member 440 on the right to rotate counterclockwise, and the knocking rod 450 on the right moves away from the feeding bin 110. When the first protrusion 421 is out of contact with the toggle rod 430, the toggle rod 430 returns to its vertical state under the action of the first torsion spring, and the transmission member 440 on the right remains in contact with the toggle rod 430 under the action of the second torsion spring.

[0045] As the sensing block 420 swings back and forth, the two knocking rods 450 alternately move away from and knock the lower part of the feed port, thereby preventing powder accumulation from clogging the feed port, thereby making the process of powder entering the feeding pipe 300 from the feeding bin 110 smoother, and further making the powder in the feeding pipe 300 more evenly distributed, thereby ensuring the processing quality and efficiency of the steel-lined fluorine parts.

[0046] In a further embodiment, a matching assembly 500 is provided between the feeding bin 110 and the steel pipe 200, and the matching assembly 500 is used to adjust the amount of powder per unit length in the feeding pipe 300 according to the diameter of the steel pipe 200. The matching assembly 500 includes a plurality of matching blocks 510; the plurality of matching blocks 510 are located in the feeding pipe 300, one of the matching blocks 510 is connected to the frame 100, and the remaining matching blocks 510 are sequentially connected to the upper matching block 510 from top to bottom, and the adjacent two matching blocks 510 are detachably connected.

[0047] The powder in the feeding bin 110 enters the feeding pipe 300 after passing through the feeding port and the feeding port 310. As the feeding pipe 300 moves axially, the powder in the feeding pipe 300 contacts the matching block 510. The powder higher than the lower surface of the lowest matching block 510 is blocked by the matching block 510 and is pushed by the matching block 510 to a position away from the steel pipe 200. When the number of matching blocks 510 is greater, the lower the height of the lower surface of the lowest matching block 510 is, and the amount of powder stored in the feeding pipe 300 per unit length is less, which is suitable for processing steel pipes 200 with smaller diameters; when the number of matching blocks 510 is less, the height of the lower surface of the lowest matching block 510 is higher, and the amount of powder stored in the feeding pipe 300 per unit length is more, which is suitable for processing steel pipes 200 with larger diameters; the present invention can be adapted to steel pipes 200 of different diameters, and has strong universality. Construction workers can select a suitable number of matching blocks 510 according to the diameter of the steel pipe 200 to be processed, as shown in FIG. Figure 4Adjacent matching blocks 510 are detachably connected, which facilitates workers to install and disassemble the matching blocks 510.

[0048] In a further embodiment, the topmost matching block 510 is fixedly connected to a second boss 511, which passes through the feeding port 310 and extends out of the feeding tube 300. The diameter of the second boss 511 is equal to the width of the feeding port 310. The matching block 510 can be rotatably connected to the frame 100 around the axis of the feeding tube 300; and the matching block 510 is fixedly connected to a paddle plate 520 on one side facing the steel pipe 200, and the paddle plate 520 extends vertically.

[0049] When the feeding tube 300 moves along its own axial direction, the second boss 511 slides in the wavy feeding port 310, thereby driving the uppermost matching block 510 to swing back and forth around the axis of the feeding tube 300 within a preset range, thereby driving the paddle 520 to swing back and forth synchronously. During the swinging process, the paddle 520 disperses the powder in the feeding tube 300 to make it looser, thereby avoiding the powder from agglomerating before being poured into the steel pipe 200, making the thickness of the lining more uniform, and ensuring the processing quality of the steel lining fluorine parts.

[0050] In a further embodiment, a cooling assembly is provided between the feeding bin 110 and the first supporting assembly 120, and the cooling assembly is in contact with the feeding tube 300, and the cooling assembly is used to cool the feeding tube 300. This prevents the powder in the feeding tube 300 from being too hot and agglomerated in the feeding tube 300.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
