[0082] A coil-type feeding machine, comprising:

[0083] A cabinet 1, wherein a support frame 11 is arranged inside the cabinet 1;

[0084] A rotating shaft 2, on which a mounting plate 3 is fixedly mounted;

[0085] The rotating shaft 2 located on one side of the mounting plate 3 is mounted on the supporting frame 11;

[0086] A positioning mechanism 4 is installed on the rotating shaft 2 located on the other side of the mounting plate 3;

[0087] The positioning mechanism 4 comprises a positioning block 41 and a cylinder 42;

[0088] The fixed end of the cylinder 42 is movably connected to the positioning block 41;

[0089] The plurality of groups of cylinders 42 are distributed in a divergent manner around the positioning block 41;

[0090] Also includes:

[0091] The winding mechanism 5 has a winding plate 51;

[0092] The winding plate 51 is slidably connected to the mounting plate 3;

[0093] The cylinder 42 drives the winding plate 51 to move linearly along the mounting plate 3;

[0094] A plurality of winding plates 51 form a ring structure for mounting nylon tube coils;

[0095] The servo motor drives the rotating shaft 2 to rotate so that the mounting plate 3, the positioning mechanism 4 and the winding mechanism 5 rotate synchronously to realize the rotation loading of the nylon tube coil;

[0096] The cylinder 42 turns inward or outward with the positioning block 41 as a fulcrum to form multiple groups of winding plates 51 that move toward or away from the rotating shaft 2 to adjust the inner diameter of the annular structure and to install nylon tube coils of different sizes.

[0097] Specifically, a coil-type feeder is used in conjunction with a nylon tube heating and forming device, installed in the process upstream of the nylon tube heating and forming device, and is used to transport the nylon tube to the nylon tube heating and forming device. The device is used to install rolled nylon tubes, that is, nylon tube coils; the device has a cabinet 1, the cabinet 1 is used to protect the internal structure for loading, a support frame 11 is arranged inside the cabinet 1, and a rotating shaft 2 is movably installed on the support frame 11. The rotating shaft 2 has a direct or indirect connection relationship with the mounting plate 3, the positioning mechanism 4, and the winding mechanism 5, and the installation and rolling feeding of the nylon tube coil are completed through their cooperation; wherein the mounting plate 3 is sleeved on the rotating shaft 2, with the mounting plate 3 as the dividing line, the rotating shaft 2 on one side of the mounting plate 3 is distributed with the positioning mechanism 4, and the rotating shaft 2 on the other side of the mounting plate 3 is connected to the supporting frame 11; at the same time, the winding mechanism 5 distributed on the same side as the positioning mechanism 4 is partially installed on the mounting plate 3, and the positioning mechanism 4 is arranged on the winding mechanism 5. The positioning mechanism 4 has a positioning block 41 and a cylinder 42, and the winding mechanism 5 has a winding plate 51. The winding plate 51 is connected to the cylinder 42. Multiple groups of winding plates 51 form an annular structure for installing nylon tube coils. The nylon tube coils have different sizes (i.e., inner diameters). In order to meet the use and installation of nylon tube coils of different sizes, the positioning mechanism 4 is adjusted and coordinated with the winding mechanism 5. Specifically, the positioning block 41 of the positioning mechanism 4 is installed on the mounting plate 3, and one end of the cylinder 42 is installed on the positioning block 41 and the other end is connected to the winding plate 51. Because the cylinder 42 and the positioning block 41 are movably connected, the cylinder 42 can rotate with the positioning block 41 as the axis. When the cylinder 42 rotates outward, it will push the winding plate 51 to expand outward. Multiple groups of winding plates 51 expand outward together, so that the inner diameter of the annular structure formed by the winding plate 51 becomes larger, and the inner diameter becomes smaller. When in use, it can be adjusted accordingly according to the inner diameter size of the nylon tube coil;

[0098] At the same time, after the nylon tube coil is installed, the cylinder 42 is used to continue to push the winding plate 51 outward, and the winding plate 51 moves outward, so that the annular structure tightens the inner ring of the nylon tube coil, so that the installation of the nylon tube coil is more stable. When the servo motor drives the rotating shaft 2 to rotate, the mounting plate 3, the positioning mechanism 4, the winding mechanism 5, and the nylon tube coil will rotate synchronously. Because the winding plate 51 firmly holds up the nylon tube coil, the nylon tube coil rotates stably during operation and will not shake excessively to affect the next process.

[0099] The cover plate 6 is fixedly mounted on the rotating shaft 2 and is located on a side of the nylon tube coil away from the mounting plate 3;

[0100] The cover plate 6 is formed with a first through hole 61 and a strip-shaped through hole 62;

[0101] The rotating shaft 2 and the winding plate 51 pass through the first through hole 61 and the strip through hole 62 in sequence.

[0102] Specifically, when using, first remove the cover plate 6, place the nylon tube coil on the winding mechanism 5, and then reinstall the cover plate 6. When installing the cover plate 6, the first through hole 61 of the cover plate 6 passes through the rotating shaft 2, and the strip through hole 62 of the cover plate 6 passes through the winding plate 51 corresponding to the position, and then use the quick lock to fix the cover plate 6 to the rotating shaft 2.

[0103] The support frame 11 comprises a support frame part 111 and a support frame part 2 112;

[0104] The first support frame 111 and the second support frame 112 are respectively provided with connecting blocks 7;

[0105] The rotating shaft 2 is movably connected to two sets of connecting blocks 7;

[0106] The servo motor is located between the first support frame 111 and the second support frame 112 .

[0107] Specifically, a part of the rotating shaft 2 is installed on the supporting frame 11 through the connecting block 7. The supporting frame 11 has a supporting frame part 111 and a supporting frame part 112. A space is left between the supporting frame part 111 and the supporting frame part 112. The space is used to install a servo motor. The servo motor provides driving force for the rotating shaft 2 to enable the entire equipment to operate. The servo motor drives the rotating shaft 2 to rotate, so that the mounting plate 3, the positioning mechanism 4, and the winding mechanism 5 rotate synchronously, thereby completing the rotational feeding of the nylon tube coil.

[0108] The positioning block 41 has an integrally formed raised portion 411 and a connecting portion 412;

[0109] A second through hole 413 is formed between the protruding portion 411 and the connecting portion 412;

[0110] The rotating shaft 2 is inserted and installed in the second through hole 413;

[0111] The protruding portion 411 is provided with a threaded through hole 414;

[0112] A screw is installed in the threaded through hole 414 until the screw is fixedly abutted against the rotating shaft 2 to achieve the connection and fixation between the positioning mechanism 4 and the rotating shaft 2 .

[0113] Specifically, the positioning block 41 is an integrally formed workpiece, the raised portion 411 of the positioning block 41 is a cylindrical structure, the connecting portion 412 connected below the raised portion 411 is a special-shaped structure, a second through hole 413 is connected between the raised portion 411 and the connecting portion 412, and the rotating shaft 2 passes through the second through hole 413; wherein a threaded through hole 414 is provided on the raised portion 411, and after the positioning block 41 is installed on the rotating shaft 2, a screw is screwed into the threaded through hole 414 until the positioning block 41 is firmly fixed on the rotating shaft 2.

[0114] A U-shaped mounting opening 415 is formed on the connecting portion 412;

[0115] The U-shaped mounting opening 415 has mounting holes 416 on both side walls;

[0116] A connecting shaft 417 is installed between the two groups of mounting holes 416;

[0117] The fixed end of the cylinder 42 is movably connected to the connecting shaft 417;

[0118] The telescopic end of the cylinder 42 is connected to the bottom surface of the winding plate 51 through the mounting seat 418.

[0119] Specifically, a plurality of groups of U-shaped mounting openings 415 are evenly distributed around the circumference of the connecting portion 412, and a connecting shaft 417 is installed on the U-shaped mounting opening 415. The fixed end of the cylinder 42 is movably connected to the connecting shaft 417, and the cylinder 42 can rotate around the connecting shaft 417. At the same time, the telescopic end of the cylinder 42 is connected to the winding plate 51. When the cylinder 42 rotates, it can push the winding plate 51 to move, thereby adjusting the size of the annular structure formed by the plurality of winding plates 51 for installing the nylon tube coil.

[0120] The winding mechanism 5 comprises:

[0121] A sliding assembly 52, the sliding assembly 52 comprises a sliding rail 521 and a sliding block 522;

[0122] The plurality of slide rails 521 are distributed in a divergent manner around the cylinder 42;

[0123] The slider 522 is slidably mounted on the slide rail 521;

[0124] A backing plate 523 is fixedly mounted on the top surface of the slider 522;

[0125] One end of the winding plate 51 is fixedly connected to the pad 523;

[0126] The telescopic end of the cylinder 42 stretches to drive the winding plate 51 to move and drive the slider 522 to move along the slide rail 521 in a direction away from the rotating shaft 2;

[0127] The telescopic end of the cylinder 42 contracts to drive the winding plate 51 to move and drive the slider 522 to move along the slide rail 521 toward the rotating shaft 2.

[0128] Specifically, the bottom of the winding plate 51 is fixedly mounted on the slider 522 through the pad 523. When the telescopic end of the cylinder 42 is stretched outward, the cylinder 42 drives the winding plate 51 to move outward. At this time, the winding plate 51 and the slider 522 move outward along the slide rail 521, that is, they are getting farther and farther away from the rotating shaft 2. Multiple groups of winding plates 51 expand outward at the same time, so that the inner diameter of the annular structure formed by the winding plate 51 becomes larger. Conversely, when the telescopic end of the cylinder 42 is retracted inward, the cylinder 42 drives the winding plate 51 to move inward. At this time, the winding plate 51 and the slider 522 move inward along the slide rail 521, that is, they are getting closer and closer to the rotating shaft 2. Multiple groups of winding plates 51 are retracted inward at the same time, so that the inner diameter of the annular structure formed by the winding plate 51 becomes smaller.

[0129] Preferably, before installing the nylon tube coil, the cylinder 42 is first flipped along the positioning block 41 to adjust the position of the winding plate 51, that is, to adjust the inner diameter of the annular structure formed by the winding plate 51. After the nylon tube coil is installed and before the equipment is started, the cylinder 42 is stretched to push the winding plate 51 outward, so that multiple groups of winding plates 51 support the inner circle of the nylon tube coil. An interaction force is generated between the nylon tube coil and the winding plate 51, so that the position of the nylon tube coil is more stable during rotation, and the nylon tube is steadily transported to the next process through rotation to ensure production quality.

[0130] The upper surface of the winding plate 51 is in an arc-shaped structure.

[0131] Specifically, the surface of the winding plate 51 in contact with the nylon tube coil is an arc-shaped surface, which better fits the curvature of the inner circle of the nylon tube coil, facilitates the rotation and feeding of the nylon tube coil, and avoids wear of the nylon tube.

[0132] A baffle 53 and an L-shaped fixing plate 54 are installed on the winding plate 51;

[0133] The bottom surface of the baffle 53 is adapted to the curvature of the upper surface of the winding plate 51;

[0134] Part of the wall of the L-shaped fixing plate 54 is connected to the baffle 53 by screws;

[0135] Another part of the wall of the L-shaped fixing plate 54 is fixedly connected to the winding plate 51 by screws.

[0136] Specifically, the nylon tube coil will inevitably be displaced when it is rotated and fed. To avoid excessive displacement of the nylon tube coil, baffles 53 and cover plates 6 are respectively arranged on both sides of the nylon tube coil, so that the position of the nylon tube coil is limited between the baffles 53 and the cover plates 6; wherein, the baffle 53 is fixedly installed on the winding plate 51, and the upper surface of the winding plate 51 is in the shape of an arc. To make the installation more fitting, the bottom of the baffle 53 is also arranged to be arc-shaped, so that it is adapted to the curvature of the upper surface of the winding plate 51, and is connected and fixed by an L-shaped fixing plate 54. During installation, the horizontal vertical section of the L-shaped fixing plate 54 is first fixed to the winding plate 51 by screws, and then the baffle 53 is fitted with the vertical vertical section of the L-shaped fixing plate 54 and is also fastened with screws, and the bottom of the baffle 53 is in contact with the upper surface of the winding plate 51, thereby fixing the baffle 53 on the winding plate 51.

[0137] A fixed sleeve 8 is fixedly sleeved on the rotating shaft 2;

[0138] The mounting plate 3 passes through the rotating shaft 2 until it abuts against the fixing sleeve 8 and is fixed by screws.

[0139] Specifically, the mounting plate 3 and the fixed sleeve 8 are both sleeved on the rotating shaft 2, the fixed sleeve 8 and the rotating shaft 2 are fixed to each other, a port on one side of the fixed sleeve 8 contacts with the mounting plate 3 and the two are fixed with screws, and the mounting plate 3 is fixedly installed by the fixed sleeve 8 to prevent the mounting plate 3 from moving.

[0140] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
