[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0029] Please see Figure 1-4 The present invention provides the following technical solution:

[0030] A glass tube processing device for a tube feeding machine includes a base 1, a clamping assembly, a fixing assembly, and a cutting assembly. A fixed platform 2 is fixedly installed on the base 1 along its length. The cutting assembly slides and adjusts along the length of the fixed platform 2. An operating table 23 with a PLC controller is also fixedly installed on one side wall of the fixed platform 2. Two fixing assemblies are provided and symmetrically arranged on both sides of the top surface of the base 1. A clamping assembly is provided between the two fixing assemblies. The clamping assembly reciprocates between the horizontal and vertical directions and clamps the glass tube on the clamping assembly.

[0031] It should be further explained that by feeding the glass tube horizontally onto the clamping assembly and clamping it in place, and then rotating the clamping assembly 90 degrees to the vertical direction so that it finally falls between the two fixed platforms 2, the fixed assembly is rotated 90 degrees to limit and fix the glass tube. After that, when cutting, the position and angle of the cutting assembly are adjusted to achieve the cutting operation of the glass tube. After the cutting is completed, the cut glass tube can be removed.

[0032] The cutting assembly includes an adjusting seat 21, a screw, a fixing plate 211, a rotating arm 22, and saw teeth 221;

[0033] Mounting seats are fixedly installed on both sides of the top surface of the fixed platform 2. A screw is rotatably set between the mounting seats on both sides, and a rotary motor is connected to one end of the screw. The rotary motor is fixedly installed on one of the mounting seats. A dovetail-shaped guide groove is also opened on the top surface of the fixed platform 2 along its length. A guide bar is fixedly installed on the bottom end of the adjusting seat 21. The guide bar slides between the inner walls of the guide groove, and the screw passes through the adjusting seat 21 and is threaded to it.

[0034] A fixed plate 211 is fixedly installed vertically on the top surface of the adjusting seat 21. A rotating arm 22 is rotatably mounted on one side wall of the fixed plate 211, and a second rotary motor is fixedly mounted on the other side wall of the fixed plate 211. The second rotary motor drives the rotating arm 22 to rotate. A third rotary motor is fixedly mounted on one side wall of the rotating arm 22. A sawtooth 221 is rotatably mounted between the inner walls of the other end of the rotating arm 22, and the third rotary motor drives the sawtooth 221 to rotate.

[0035] It should be further explained that during cutting, the first rotary motor is started to control the rotation of the first screw, thereby controlling the position of the adjusting seat 21. After adjusting to the appropriate position, it stops. Then, the third rotary motor is started to make the saw teeth 221 start working. At the same time, the second rotary motor is started to make the rotating arm 22 drive the saw teeth 221 to rotate and cut the glass tube. After the glass tube is completely cut, the third rotary motor is stopped and the second rotary motor is stopped after the rotating arm 22 is reset.

[0036] The clamping assembly includes a gear 51, a rack 111, a rotating shaft 5, a fixed arm 6, a connecting arm 61, and a connecting rod 611;

[0037] The rotating shaft 5 is rotatably mounted between the opposite side walls of the two fixed seats 3. Two gears 51 are mounted on the rotating shaft 5 and rotate synchronously with it. The gears 51 are incomplete gears. A fixed groove is opened on the base 1 below the gears 51. A screw 2 is rotatably mounted in the fixed groove. A rotary motor 4 (not shown in the figure) is connected to one end of the screw 2 to drive it. The rotary motor 4 is mounted between the inner walls of the base 1. A "convex" shaped moving part 11 is slidably mounted between the inner walls of the fixed groove. A rack 111 is fixed on the top surface of the moving part 11 and meshes with the gears 51 for transmission.

[0038] Two fixed arms 6 are symmetrically arranged and are both fixed to the rotating shaft 5 and rotate synchronously with it. The connecting arm 61 is movably set on one end of the fixed arm 6 by an electric cylinder. The electric cylinder is installed between the inner walls of the fixed arm 6. Connecting rods 611 are rotatably set on both side walls of the end of the connecting arm 61. A rotary motor 5 is installed between the inner walls of the connecting arm 61. The rotary motor 5 drives the connecting rod 611 on one side, and the connecting rod 611 on the other side rotates synchronously and adjusts under the action of the shaft connection rotation. A positioning clamp is fixedly installed between the two connecting rods 611 on the same side of the connecting arm 61. A sponge pad is glued to the arc surface of the positioning member.

[0039] It should be further explained that by placing the glass tube between the positioning clamps on both sides, starting the rotary motor five, which drives the connecting rod 611 to rotate and adjust until the sponge pad on the positioning clamp firmly clamps the glass tube, then stopping. Subsequently, starting the rotary motor four, which drives the screw two to rotate, thereby controlling the horizontal movement of the rack 111. As the rack 111 moves, the gear 51 rotates and drives the rotating shaft 5 to rotate, thereby causing the fixed arm 6 to rotate synchronously with the rotating shaft 5. This causes the glass tube, which is in a horizontal position, to be driven to rotate in the vertical direction. If the vertical rotation is too high, the electric cylinder can be started to lower the height until the glass tube falls between the arc surfaces of the two fixed platforms 2. After the fixing components clamp the glass tube, the electric cylinder is reset to its shortest position, and then adjusted to the horizontal direction and stopped.

[0040] The fixing assembly includes an adjusting cover 4, a limiting block 42, and a limiting plate 43. Two supports 31 are fixedly installed on one vertical side wall of the fixing base 3. The supports 31 are rotatably connected by a shaft. A rotary motor 6 is fixedly installed on the side wall of one of the supports 31. The rotating shaft is driven by the rotary motor 6. An "L"-shaped connecting block is connected to one end of the adjusting cover 4. The rotating shaft passes through the connecting block and is fixed to it as a whole.

[0041] The top surface of the fixed base 3 is provided with an arc surface one, and the adjustment cover 4 is provided with an arc surface two. The arc surface one matches the arc surface two. Two fixed cylinders 41 are fixedly installed on one side wall of the adjustment cover 4. A piston shaft is elastically slidably arranged between the inner walls of the fixed cylinders 41, and a spring (not shown in the figure) is connected between the end of the piston shaft and the inner wall of the fixed cylinder 41. The other end of the piston shaft passes through the adjustment cover 4 and a limiting plate 43 is connected to its end. The limiting plate 43 is arranged in an arc shape.

[0042] Two electric push rods are fixed on the other side wall of the adjusting cover 4, and a limit block 42 is slidably provided between the inner walls of the adjusting cover 4. A sponge pad is glued to the side surface of the limit block 42 facing the location of the arc surface 2. The push rod end of the electric push rod is connected and fixed to the limit block 42.

[0043] It should be further explained that, in the initial state, the fixed components, such as Figure 4 As shown, the glass tube is positioned on the fixed platform 2. In this state, the glass tube can be smoothly placed between the arc surfaces of the two fixed platforms 2. After the glass tube falls onto the arc surface, the rotating motor 6 is started, causing the connecting block to rotate 90 degrees to the side of the fixed platform 2. This makes one end of the adjusting cover 4 contact the top surface of the fixed platform 2 after rotation. The limiting plate 43 gradually contacts the top surface of the glass tube and is pushed upward during the rotation of the adjusting cover 4 to match the thickness of the glass tube. Then, the electric push rod is started, causing the limiting block 42 to move to the side of the glass tube until the sponge pad on the connecting block is tightly attached to the outer surface of the glass tube. The electric push rod is then stopped. At this point, the glass tube is clamped and fixed between the two fixed platforms 2 and the adjusting cover 4.

[0044] It should be noted that the connection methods described above, such as "fixed installation / fixed connection", are not limited to welding, bolt / screw connection or threaded connection, as long as the fixed state between the two structures can be guaranteed.

[0045] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
