[0096] Specifically, a nylon tube bending machine, when in use, the overall structures of the equipment need to be arranged in sequence, and corresponding safety warning lines are set around the equipment, and then the equipment parameters are adjusted through the control console 5. After completing all preparations, the staff installs the nylon tube coil on the feeding assembly 6, pulls up one end of the nylon tube through the tube buffer rack 7 to extend it to the feeding assembly 2, and inserts the pulled nylon tube into the inlet of the heating assembly 3, and then starts the equipment. The feeding assembly 6 will continue to rotate, and the nylon tube coil will continue to be fed during the rotation process. At the same time, the feeding assembly 2 clamps and pulls the nylon tube, so that the nylon tube is gradually transmitted to the heating assembly 3, and the nylon tube passing through the heating assembly 3 is transmitted to the bending assembly 4 for bending processing, and the formed nylon tube is cooled and cut in conjunction with the air cooling system and the cutting device.

[0097] Among them, the cutting device is used to cut the nylon tube after bending. The cutting device has a tool and a cylinder, which is assembled on one side of the bending tube assembly 4.

[0104] The first circulating fan 34 and the second circulating fan 35 form circulating hot air and the heating rod 33 dissipates heat so that the nylon tube is heated evenly.

[0105] Specifically, the nylon tube passes through the oven 31 and extends into the electric heating tube 32. When the nylon tube 31 is in the oven 31, the heating rod 33 in the oven 31 will continuously dissipate heat to heat the nylon tube. At the same time, the front and rear sides of the overall oven 31 are connected with a first circulation fan 34 and a second circulation fan 35. The first circulation fan 34 and the second circulation fan 35 send hot air into the oven 31. The hot air flows in and out to form a circulation mode. The nylon tube in the oven 31 has a certain length. Two groups of circulation fans are set to ensure that the internal temperature of the oven 31 is constant, so that the nylon tube is heated more evenly; the nylon tube heated by the oven 31 continues to be transmitted to the electric heating tube 32. The outlet end of the electric heating tube 32 is connected to the bending pipe assembly 4, so that the nylon tube is bent in a heated state, thereby ensuring the processing accuracy of the nylon tube and optimizing product quality.

[0110] The plurality of groups of air diffusion holes 82 are evenly arranged and correspond to the positions of the nylon tubes bent and formed on the bent tube assembly 4 .

[0111] Specifically, the cold air outlet portion 81 of the air cooling system is configured to be composed of a plurality of groups of air diffusion holes 82, which are arranged in sequence and correspond to the nylon tube bent on the bent tube assembly 4. Compared with the original method of directly blowing out cold air through the cooling air pipe for cooling treatment, the area of ​​the cold air blown out by the air diffusion holes 82 is increased, and the cold air blown out of the corresponding nylon tube is more uniform, which can further ensure the molding quality of the nylon tube.

[0112] The feeding assembly 2 includes a mounting seat 21, a lead screw 22, a traction mechanism 23 and a driving mechanism 24;

[0113] The mounting seat 21 is provided with a lead screw 22 along its length direction;

[0114] The traction mechanism 23 is mounted on the mounting seat 21;

[0115] The traction mechanism 23 is formed with a traction upper portion 231 and a traction lower portion 232;

[0116] A mounting channel for clamping the nylon tube is formed between the traction upper portion 231 and the traction lower portion 232;

[0124] The loading assembly 6 includes a cabinet 61, a support frame 62, a rotating shaft 63 and a mounting plate 64;

[0125] The support frame 62 is located inside the cabinet 61;

[0126] The mounting plate 64 is fixedly mounted on the rotating shaft 63;

[0127] The rotating shaft 63 located on one side of the mounting plate 64 is mounted on the supporting frame 62;

[0128] A positioning mechanism 65 is installed on the rotating shaft 63 located on the other side of the mounting plate 64;

[0129] The positioning mechanism 65 comprises a positioning block 651 and a cylinder 652;

[0130] The fixed end of the cylinder 652 is movably connected to the positioning block 651;

[0131] The multiple groups of cylinders 652 are distributed in a divergent manner around the positioning block 651;

[0132] Also includes:

[0133] The winding mechanism 66 has a winding plate 661;

[0134] The winding plate 661 is slidably connected to the mounting plate 64;

[0135] The cylinder 652 drives the winding plate 661 to move linearly along the mounting plate 64;

[0136] Multiple sets of winding plates 661 form a ring structure for installing nylon tube coils;

[0137] The servo motor drives the rotating shaft 63 to rotate so that the mounting plate 64, the positioning mechanism 65 and the winding mechanism 66 rotate synchronously to realize the rotation loading of the nylon tube coil;

[0138] The cylinder 652 turns inward or outward with the positioning block 651 as a fulcrum to form multiple groups of winding plates 661 that move toward or away from the rotating shaft 63 to adjust the inner diameter of the annular structure and to install nylon tube coils of different sizes.

[0139] Specifically, the feeding assembly 6 is installed upstream of the process of the tube buffer rack 7, and is used to install the rolled nylon tube, that is, the nylon tube coil; the feeding assembly 6 has a cabinet 61, the cabinet 61 is used to protect the internal structure for feeding, and a support frame 62 is arranged inside the cabinet 61, and a rotating shaft 63 is movably installed on the support frame 62, and the rotating shaft 63 has a direct or indirect connection relationship with the mounting plate 64, the positioning mechanism 65, and the winding mechanism 66, and the installation and rolling feeding action of the nylon tube coil are completed through their cooperation; wherein, the mounting plate 64 is sleeved on the rotating shaft 63, with the mounting plate 64 as the dividing line, the rotating shaft 63 on one side of the mounting plate 64 is distributed with the positioning mechanism 65, and the rotating shaft 63 on the other side of the mounting plate 64 is connected to the supporting frame 62; at the same time, the winding mechanism 66 distributed on the same side as the positioning mechanism 65 is partially installed on the mounting plate 64, and the positioning mechanism 65 has a positioning block 651, a cylinder 652, and the winding mechanism 66 6 has a winding plate 661, which is connected to the cylinder 652. Multiple groups of winding plates 661 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 65 is adjusted and coordinated with the winding mechanism 66. Specifically, the positioning block 651 of the positioning mechanism 65 is installed on the mounting plate 64, one end of the cylinder 652 is installed on the positioning block 651, and the other end is connected to the winding plate 661. Because the cylinder 652 and the positioning block 651 are movably connected, the cylinder 652 can rotate with the positioning block 651 as the axis. When the cylinder 652 rotates outward, it will push the winding plate 661 to expand outward. Multiple groups of winding plates 661 expand outward together, so that the inner diameter of the annular structure formed by the winding plate 661 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.

[0140] At the same time, after the nylon tube coil is installed, the cylinder 652 is used to continue to push the winding plate 661 outward. The winding plate 661 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 63 to rotate, the mounting plate 64, the positioning mechanism 65, the winding mechanism 66, and the nylon tube coil will rotate synchronously. Because the winding plate 661 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.

[0142] The first buffer wheel part 73 and the second buffer wheel part 74 are movably connected to the support column 72 through the connecting shaft 75 respectively;

[0143] The buffer wheel part 1 73 is located above the buffer wheel part 2 74;

[0144] The nylon tube that is rotated and fed by the feeding assembly 6 is sequentially wound around the buffer wheel part 1 73 and the left side of the buffer wheel part 2 74 and reversely wound, and extends to the feeding assembly 2 through the top of the buffer wheel part 73 .

[0145] The buffer wheel part 73 forms a first limiting groove part 731 and a second limiting groove part 732;

[0146] The buffer wheel part 2 74 forms a limiting groove part 3 741;

[0147] The nylon tube extends into the feeding assembly 2 through the first limiting groove 731 , the third limiting groove 741 , and the second limiting groove 732 in sequence.

[0148] Specifically, the nylon tube installed on the loading assembly 6 passes through the tube buffer rack 7 and enters the feeding assembly 2. The feeding assembly 2 is installed in the fuselage 1. The loading assembly 6 is a device independent of the fuselage 1. There is a corresponding distance between the two. In order to avoid the position displacement of the nylon tube during the transmission process, the tube buffer rack 7 is installed between the loading assembly 6 and the feeding assembly 2. The nylon tube surrounds the buffer wheel part 1 73 and the buffer wheel part 2 74 for one week and then is transmitted to the feeding assembly 2. The nylon tube is embedded in the limiting groove part 1 731 on the left side of the buffer wheel part 1 73 from top to bottom, and continues to be embedded downward into the limiting groove part 3 741 on the left side of the buffer wheel part 2 74, and then surrounds and embeds in the limiting groove part 2 732 in the direction of the buffer wheel part 1 73 from bottom to top, and finally stretches and moves in the direction of the feeding assembly 2, thereby buffering the nylon tube between the loading assembly 6 and the feeding assembly 2, so that the nylon tube is transmitted more stably, assisting loading and feeding, and ensuring processing accuracy.

[0149] Furthermore, a device for laser marking the nylon tube can be arranged between the tube buffer rack 7 and the feeding assembly 2. During the process of the nylon tube passing through the tube buffer rack 7 and being transmitted to the feeding assembly 2, this section of nylon tube can be marked. The marking device is used online with the tube bending machine to form a link in the process and realize production automation.

[0150] A nylon tube bending machine includes the following construction processes:

[0151] Step 1: Place the nylon tube coil
