[0025] The technical solution of the utility model is described in detail with specific embodiments below. The following specific embodiments can be combined or replaced with each other according to actual conditions, and the same or similar concepts or processes may not be repeated in some embodiments. Example

[0026] like Figures 1 to 5 As shown, the utility model provides a number tube feeding and cutting device, comprising a motor 1, a transmission mechanism 2, a mounting seat 3, and a fixed-length feeding mechanism 4, a cutting mechanism 5, a switching feeding mechanism 6 and an ejection mechanism 7 installed on the mounting seat 3; the transmission mechanism comprises a first transmission member 21 and a camshaft 22, the camshaft 22 is installed on the mounting seat 3, the first transmission member 21 is respectively connected to the motor 1 and the camshaft 22, and the camshaft 21 is provided with a fixed-length feeding cam 221, a cutting cam 222, a switching feeding cam 223 and an ejection cam 224 which are respectively connected to the fixed-length feeding mechanism 4, the cutting mechanism 5, the switching feeding mechanism 6 and the ejection mechanism 7.

[0027] The utility model provides a fixed-length feeding cam 221, a cutting cam 222, a switching feeding cam 223 and an ejection cam 224 which are respectively connected to the fixed-length feeding mechanism 4, the cutting mechanism 5, the switching feeding mechanism 6 and the ejection mechanism 7 on the cam shaft 22, and the rotation of the cam shaft 22 drives each cam to rotate, thereby driving each mechanism to work. The cam transmission is suitable for high-speed operation occasions and has a high transmission efficiency. Therefore, the device can realize high-speed cutting and ejection of the number tube, and effectively improve the processing efficiency.

[0028] Specifically, the fixed-length feeding mechanism 4 includes a positioning plate 41 and a fixed-length feeding cam follower frame 42, a guide tube 43, a pressure wheel 44, a synchronous belt transmission member 45 and a one-way roller shaft 46 installed on the positioning plate 41; the positioning plate 41 is installed on the mounting seat 3, the guide tube 43 is arranged at the front end and the end of the positioning plate 41, the number tube passes through the guide tube 43, the pressure wheel 44 presses the number tube, the fixed-length feeding cam follower frame 42 is respectively connected to the synchronous belt transmission member 45 and the fixed-length feeding cam 221, the fixed-length feeding cam 221 rotates, drives the fixed-length feeding cam follower frame 42 to move forward, and the synchronous belt transmission member 45 drives the one-way roller shaft 46 to rotate, and the one-way roller shaft 46 is fixedly installed with a driving wheel 451, the driving wheel 451 is connected to the pressure wheel 44, and the rotation of the driving wheel 451 drives the number tube to move in the discharge direction. When the fixed-length feeding cam 221 is at the return angle, the fixed-length feeding cam follower frame 42 is pulled back by the spring arranged thereon, and the synchronous belt transmission member 45 also rotates in the opposite direction. However, the one-way roller shaft 45 is installed with a one-way bearing 452. Therefore, when the synchronous belt transmission member 45 reverses, the one-way roller shaft 45 does not follow, that is, the driving wheel 451 does not rotate and the number tube will not be retracted, thereby achieving the effect of intermittent feeding, so that the length of the number tube that needs to be cut is more accurate.

[0029] Specifically, the cutting mechanism 5 includes a cutting cam follower frame 51, a cutting top strip 52, a knife holder 53 and a cutting knife 54; the cutting cam follower frame 51 is connected to the cutting cam 222 by transmission, the cutting top strip 52 is fixedly mounted on the cutting cam follower frame 51, and the cutting knife 54 is mounted on the top of the knife holder 53. The blade of the cutting knife 54 is coaxially arranged with the discharge port of the fixed-length feeding mechanism 4. When the fixed-length feeding mechanism 4 delivers the number tube, the cutting cam 222 approaches the far rest position, and at the same time drives the cutting cam follower frame 51 to move forward, so that the cutting top strip 52 pushes the bottom of the knife holder 53 to close the blade of the cutting knife 54 of the knife holder 53, thereby cutting the number tube. When the cutting cam 222 reaches the return angle, the cutting top strip 52 is pulled back by the spring in the cutting cam follower frame 51, and the cutting knife 53 is reset.

[0030] Specifically, the switching feeding mechanism 6 includes a switching feeding cam follower frame 61, a connecting rod transmission member 62, a material picking arm 63 and a second limiting bolt 64; the switching feeding cam follower frame 61 is respectively connected to the connecting rod transmission member 62 and the switching feeding cam 223, the connecting rod transmission member 62 drives the material picking assembly 63 to reciprocate, the material picking assembly 63 includes a material picking arm 631, and the second limiting bolt 64 is arranged at the starting position of the movement of the material picking arm 631. When the material picking arm 631 is in the starting position, the material picking port of the material picking arm 631 and the material discharge port of the fixed-length feeding mechanism 4 are on the same axis. The purpose of the second limiting bolt 64 is to ensure that when picking up materials, the material picking port of the material picking arm 631 is directly opposite to the material discharge port of the fixed-length feeding mechanism 4 without offset, so that the material picking work can be carried out normally without affecting the processing efficiency. When the number tube is cut off, the switching feed cam 223 enters the lift angle, driving the switching feed cam follower frame 61 to move forward, so that the connecting rod transmission member 62 drives the material picking arm 631 to move forward to the position of the ejection mechanism 7, and the transfer is completed. When the switching feed cam 223 reaches the return angle, the switching feed cam follower frame 61 performs a return motion and drives the connecting rod transmission member 62 to drive the material picking arm 63 to reset. Furthermore, in order to increase the adjustability of the switching feed mechanism 6, the material picking assembly 63 also includes a sliding plate 632, a countersunk groove is provided at the end of the material picking arm 631, and a threaded hole is provided on the sliding plate 632. The material picking arm 631 is fixedly connected to the sliding plate 632 by bolts.

[0031] Specifically, the ejection mechanism 7 includes an ejection cam follower frame 71 and an ejection rod 72; the ejection cam follower frame 71 is in transmission connection with the ejection cam 224, and the ejection rod 72 is mounted on the ejection cam follower frame 71. When the ejection cam 224 reaches the lift angle, the ejection cam follower frame 71 is driven to move forward, so that the ejection rod 72 ejects the number tube in the material taking arm 63. When the ejection cam 224 reaches the return angle, the ejection cam follower frame 71 performs a return motion to reset the ejection rod 72.

[0032] Specifically, the first transmission member 21 includes a synchronous belt 211 and two synchronous pulleys 212. The two synchronous pulleys 212 are respectively mounted on the camshaft 22 and the motor 1, and the synchronous belt 211 is sleeved on the two synchronous pulleys 212. The stable meshing between the synchronous pulleys 212 and the synchronous belt 211 avoids impact and vibration during the transmission process. The stable transmission also helps to reduce noise during the transmission process. It can be understood that the first transmission member 21 can also use two gears for transmission.

[0033] The specific working process of the device in this embodiment is as follows: first, the number tube is passed through the guide tube 43 of the fixed-length feeding mechanism 4 and placed between the driving wheel 461 and the pressing wheel 44, and the motor 1 is started to make the first transmission member 21 drive the camshaft 22 to rotate. The shapes and sizes of the cams on the camshaft 22 are different. When the fixed-length feeding cam 221 drives the fixed-length feeding cam follower frame 42 to move forward, the synchronous belt transmission member 45 drives the one-way roller shaft 46 to rotate, and then drives the driving wheel 461 to rotate to transport the number tube in the discharge direction; when the fixed-length feeding mechanism 4 sends the number tube out, the cam 22 is cut off. 22 approaches the far rest position, and at the same time drives the cutting cam follower frame 51 to move forward, so that the cutting top strip 52 pushes open the bottom of the knife frame 53 so that the blade of the cutting knife 54 of the knife frame 53 is closed, thereby cutting off the number tube; when the number tube is cut off, the switching feeding cam 223 enters the lift angle, drives the switching feeding cam follower frame 61 to move forward, and makes the connecting rod transmission member 62 drive the material picking arm 631 to move forward to the position of the ejection mechanism 7, and completes the transfer; when the ejection cam 224 reaches the lift angle, drives the ejection cam follower frame 71 to move forward, so that the ejection rod 72 ejects the number tube in the material picking arm 63. Example

[0034] In order to effectively transport the number tubes, the fixed-length feeding mechanism 4 also includes a retaining frame 47 and a quick clamp 48. The retaining frame 47 and the quick clamp 48 are installed on the positioning plate 41. The retaining frame 47 is connected to the clamping wheel 44. A rubber hammer 481 is installed at the front end of the quick clamp 48. The rubber hammer 481 abuts against the retaining frame 47. When the clamping force of the clamping wheel 44 is insufficient, it cannot provide sufficient friction force to transport the number tubes in the discharging direction. By pressing the quick clamp 48, the rubber hammer 481 clamps the retaining frame 47 to provide additional clamping force for the clamping wheel 44, thereby ensuring smooth transportation of the number tubes. Example

[0035] In order to adjust the delivery length of the number tube, a fixed-length limit adjustment frame 49 is installed at the starting position of the movement of the fixed-length feeding cam follower frame 42, and a first limit bolt 491 is installed on the fixed-length limit adjustment frame 49. When the fixed-length feeding cam follower frame 42 is in the starting position, the first limit bolt 491 abuts against the fixed-length feeding cam follower frame 42. By changing the elongation of the first limit bolt 491 and then adjusting the starting position of the fixed-length feeding cam follower frame 42, the movement stroke of the feeding cam follower frame 42 is changed, and the delivery length of the number tube can be adjusted.

[0036] In addition to the above-mentioned preferred embodiments, the present invention also has other implementation modes. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection requested by the present invention.
