Description

Technical Field

[0001] This utility model relates to the field of finned tube processing technology, and in particular to an automatic feeding device for finned tube production. Background Technology

[0002] Finned tubes are enhanced heat transfer elements that significantly increase the heat transfer surface area by adding fins. They are widely used in heat exchangers, boilers, air conditioning condensers, industrial waste heat recovery and other fields. When processing finned tubes, an automatic feeding device is required to feed the raw tubes.

[0003] In the existing technology, most automatic feeding equipment for finned tube production conveys and feeds raw material tubes through transmission rollers and auxiliary rollers. Since the height of the feeding equipment is difficult to adjust, it is difficult to align the raw material tubes with the processing port of the subsequent processing equipment when feeding different raw material tubes. Secondly, the simple setting of transmission rollers and auxiliary rollers is not enough to effectively limit the raw material tubes, making it easy for the raw material tubes to deviate during feeding. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic feeding device for finned tube production, so as to solve the problems mentioned in the background art, which are that it is difficult to align the raw material tubes with the processing port of the subsequent processing equipment when feeding different raw material tubes, and it is difficult to effectively limit the raw material tubes, making it easy for the raw material tubes to deviate during feeding.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: It includes a height adjustment mechanism, comprising a support base, a stabilizing plate, a limiting groove, a support frame, a drive motor, a drive threaded rod, and an internal threaded moving rod. A feeding mechanism is provided at the top of the height adjustment mechanism, comprising a conveying frame, transmission rollers, a servo motor, auxiliary rollers, and a limiting block. A stabilizing mechanism is provided on the inner wall of the feeding mechanism, comprising a fixed frame, a drive groove, a bidirectional threaded ball screw, a rotary knob, an internal threaded moving block, an arc-shaped connecting frame, a clamping frame, a roller frame, and clamping rollers.

[0006] In a preferred embodiment, the top of the support base is fixedly connected to the bottom of the stabilizing plate, and a limiting groove is provided inside the stabilizing plate; the bottom of the support base is fixedly connected to the top of the support frame.

[0007] In a preferred embodiment, the top of the support frame is fixedly connected to the bottom of the drive motor, and the output end of the drive motor is fixedly connected to the bottom end of the drive threaded rod through a coupling. The outer wall of the drive threaded rod is threadedly connected to the inner wall of the internal threaded moving rod.

[0008] In a preferred embodiment, the top of the support base is movably connected to the bottom of the conveyor frame, and the bottom of the conveyor frame is fixedly connected to the top of the internal threaded moving rod. The two sides of the inner wall of the conveyor frame are rotatably connected to the two ends of the conveying rollers, respectively.

[0009] In a preferred embodiment, one end of the transmission roller is fixedly connected to the output end of the servo motor via a coupling, and the two sides of the inner wall of the conveyor frame are rotatably connected to the two ends of the auxiliary roller, respectively. Both sides of the conveyor frame are movably connected to one side of the limiting block, and the outer wall of the limiting block is movably connected to the inner wall of the limiting groove.

[0010] In a preferred embodiment, the inner wall of the conveyor frame is fixedly connected to the bottom of the fixed frame, and the fixed frame is located at the bottom of the auxiliary roller, with a drive groove provided inside the fixed frame.

[0011] In a preferred embodiment, the inner wall of the drive groove is rotatably connected to the outer wall of one end of the bidirectional threaded ball screw via a bearing, and the other end of the bidirectional threaded ball screw is fixedly connected to one end of the rotary knob. The outer walls of both ends of the bidirectional threaded ball screw are respectively threadedly connected to the inner wall of the internal threaded moving block.

[0012] In a preferred embodiment, the top of the internal threaded moving block is fixedly connected to the bottom of the arc-shaped connecting frame, and the top of the arc-shaped connecting frame is fixedly connected to the bottom of the clamping frame. One side of the clamping frame is fixedly connected to one side of the roller frame. The inner wall of the roller frame is rotatably connected to both ends of the clamping roller. The arc-shaped connecting frame is located on the outer wall of the auxiliary roller and does not contact the auxiliary roller.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, the drive motor is started to drive the drive threaded rod to rotate. As the drive threaded rod rotates, the internal threaded moving rod moves upward. The movement of the internal threaded moving rod drives the conveyor frame to move upward. The movement of the conveyor frame drives the limiting block to move inside the limiting groove, thereby adjusting the height of the conveyor frame. By adjusting the height of the conveyor frame, the limited raw material tube can be aligned with the feeding point of the subsequent processing equipment, which facilitates the limiting of different raw material tubes.

[0015] 2. In this utility model, the raw material tube is placed inside the conveyor frame, and the raw material tube is positioned on top of the conveying roller and the auxiliary roller. Then, rotating the knob drives the bidirectional threaded ball screw to rotate. The rotation of the bidirectional threaded ball screw causes the internal thread moving blocks to move relative to each other against the outer walls of the two ends of the bidirectional threaded ball screw. This, in turn, drives the arc-shaped connecting frame to move. The movement of the arc-shaped connecting frame drives the clamping frame to move, which in turn drives the roller frame to move towards the outer wall of the raw material tube, so that the clamping roller contacts the raw material tube. This facilitates the clamping and stabilization of the raw material tube and reduces the phenomenon of the raw material tube shifting during feeding. Attached Figure Description

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.

[0024] Please see Figures 1-5 This utility model provides a technical solution comprising: a height adjustment mechanism 1, which includes a support base 101, a stabilizing plate 102, a limiting groove 103, a support frame 104, a drive motor 105, a drive threaded rod 106, and an internal threaded moving rod 107. A feeding mechanism 2 is provided on the top of the height adjustment mechanism 1, which includes a conveying frame 201, a transmission roller 202, a servo motor 203, an auxiliary roller 204, and a limiting block 205.

[0025] In one embodiment, the top of the support base 101 is fixedly connected to the bottom of the stabilizing plate 102, and a limiting groove 103 is provided inside the stabilizing plate 102. The bottom of the support base 101 is fixedly connected to the top of the support frame 104.

[0026] Specifically, the stability of the conveyor frame 201 is increased by setting up the stabilizing plate 102.

[0027] In one embodiment, the top of the support frame 104 is fixedly connected to the bottom of the drive motor 105, and the output end of the drive motor 105 is fixedly connected to the bottom end of the drive threaded rod 106 through a coupling. The outer wall of the drive threaded rod 106 is threadedly connected to the inner wall of the internal threaded moving rod 107.

[0028] Specifically: the drive motor 105 is started to drive the drive threaded rod 106 to rotate. As the drive threaded rod 106 rotates, the internal threaded moving rod 107 moves upward. The movement of the internal threaded moving rod 107 causes the conveyor frame 201 to move upward.

[0029] In one embodiment, the top of the support base 101 is movably connected to the bottom of the conveyor frame 201, and the bottom of the conveyor frame 201 is fixedly connected to the top of the internal thread moving rod 107. The two sides of the inner wall of the conveyor frame 201 are rotatably connected to the two ends of the conveying roller 202 respectively.

[0030] Specifically: The servo motor 203 is started to drive the transmission roller 202 to rotate, which in turn drives the raw material tube to be fed through the auxiliary roller 204.

[0031] In one embodiment, one end of the transmission roller 202 is fixedly connected to the output end of the servo motor 203 via a coupling, and the two sides of the inner wall of the conveyor frame 201 are rotatably connected to the two ends of the auxiliary roller 204 respectively. Both sides of the conveyor frame 201 are movably connected to one side of the limiting block 205, and the outer wall of the limiting block 205 is movably connected to the inner wall of the limiting groove 103.

[0032] Specifically, the stability of the conveyor frame 201 during movement is ensured by the movable connection between the outer wall of the limiting block 205 and the inner wall of the limiting groove 103.

[0033] In one embodiment, the inner wall of the conveyor frame 201 is fixedly connected to the bottom of the fixed frame 301, and the fixed frame 301 is located at the bottom of the auxiliary roller 204. The fixed frame 301 has a drive groove 302 inside.

[0034] Specifically, it facilitates the clamping and stabilization of the raw material tube, reducing the phenomenon of the raw material tube shifting during feeding.

[0035] In one embodiment, the inner wall of the drive groove 302 is rotatably connected to the outer wall of one end of the bidirectional threaded ball screw 303 via a bearing, and the other end of the bidirectional threaded ball screw 303 is fixedly connected to one end of the rotary knob 304. The outer walls of both ends of the bidirectional threaded ball screw 303 are respectively threadedly connected to the inner wall of the internal threaded moving block 305.

[0036] Specifically: Rotating the knob 304 causes the bidirectional threaded ball screw 303 to rotate, and the rotation of the bidirectional threaded ball screw 303 causes the internal thread moving blocks 305 to move relative to each other, respectively attached to the outer walls of the two ends of the bidirectional threaded ball screw 303.

[0037] In one embodiment, the top of the internal thread moving block 305 is fixedly connected to the bottom of the arc-shaped connecting frame 306, and the top of the arc-shaped connecting frame 306 is fixedly connected to the bottom of the clamping frame 307. One side of the clamping frame 307 is fixedly connected to one side of the roller frame 308. The inner wall of the roller frame 308 is rotatably connected to both ends of the clamping roller 309. The arc-shaped connecting frame 306 is located on the outer wall of the auxiliary roller 204, and the arc-shaped connecting frame 306 does not contact the auxiliary roller 204.

[0038] Specifically, the arc-shaped connecting frame 306 facilitates the movement of the clamping frame 307 and avoids the impact on the auxiliary roller 204 when the clamping frame 307 moves.

[0039] Working principle: The raw material tube is placed inside the conveyor frame 201, with the tube positioned on top of the conveyor rollers 202 and auxiliary rollers 204. Rotating the knob 304 drives the bidirectional threaded ball screw 303 to rotate. This rotation causes the internal thread moving blocks 305 to move relative to each other against the outer walls of both ends of the ball screw 303. This, in turn, moves the arc-shaped connecting frame 306. The movement of the arc-shaped connecting frame 306 then moves the clamping frame 307, which in turn moves the roller frame 308 towards the outer wall of the raw material tube. The movement causes the clamping roller 309 to contact the raw material tube. Then, the drive motor 105 is started to drive the drive threaded rod 106 to rotate. As the drive threaded rod 106 rotates, the internal threaded moving rod 107 moves upward. The movement of the internal threaded moving rod 107 causes the conveyor frame 201 to move upward. The movement of the conveyor frame 201 causes the limiting block 205 to move inside the limiting groove 103, thereby adjusting the height of the conveyor frame 201. The servo motor 203 is started to drive the transmission roller 202 to rotate, thereby driving the raw material tube to be fed through the auxiliary rolling of the auxiliary roller 204.

[0040] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
