[0024] like Figures 1 to 4As shown, the utility model provides an automatic bone threading machine, which includes a casing 1, a bone threading seat 2 arranged in the casing 1, a material bin 3 arranged on the bone threading seat 2, a feeding plate 4 slidably arranged between the bottom port of the material bin 3 and the top surface of the bone threading seat 2, a feeding drive mechanism 5 installed in the casing 1 and used to drive the feeding plate 4 to move back and forth, a material limiting pressure roller 6 rotatably connected to the inner wall of the material bin 3, a rotation drive mechanism 7 installed in the casing 1 or the material bin 3 and used to drive the material limiting pressure roller 6 to rotate, a side push plate 8 slidably connected to the bone threading seat 2, a side push drive mechanism 9 installed in the casing 1 and used to drive the side push plate 8 to move back and forth, a push rod 30 slidably connected to the bone threading seat 2, and a push drive mechanism installed in the casing 1 and used to drive the push rod 30 to move back and forth. Structure 29, the feed plate 4 is provided with a feed trough 10, the feed trough 10 is used to carry a rubber bone in the silo 3, the top surface of the rubber bone seat 2 is recessed with a receiving trough 11 for communicating with the feed trough 10, the receiving trough 11 is located outside the silo 3, the middle part of the rubber bone seat 2 is provided with a rubber bone passage 12, the side of the rubber bone seat 2 is provided with a side push groove 13, one side of the side push groove 13 is communicated with the rubber bone passage 12, the bottom port of the receiving trough 11 is communicated with the side push groove 13, the push rod 30 can be inserted into the rubber bone passage 12, and the side push plate 8 can be inserted into the side push groove 13; when the feed plate 4 is feeding and moving, the feed trough 10 is communicated with the receiving trough 11 after passing through the limiting pressure roller 6; the rubber bone seat 2 is provided with a sleeve nozzle 14, and the sleeve nozzle 14 is communicated with the discharge port of the rubber bone passage 12. Specifically, the feed plate 4 is parallel to the side push plate 8, the feed plate 4 is located above the side push plate 8, the feeding direction of the feed plate 4 is perpendicular to the axial direction of the limiting roller 6, and the pushing direction of the pushing rod 30 is parallel to the axial direction of the limiting roller 6; the gap between the limiting roller 6 and the feed plate 4 is smaller than the thickness of the bone to ensure that the feed plate 4 only transports one bone at a time.

[0025] In actual application, a large amount of bone is stored in the silo 3, and the cloth to be worn on the bone is sleeved outside the sleeve nozzle 14. The feeding trough 10 of the feeding plate 4 is located in the silo 3, and the bone in the silo 3 falls into the feeding trough 10. The feeding drive mechanism 5 drives the feeding plate 4 and the bone in the feeding trough 10 to move toward the direction close to the receiving trough 11 to feed the bone. In the process of feeding by the feeding plate 4, the feeding plate 4 passes through the limiting roller 6, and the rotating driving mechanism 7 drives the limiting roller 6 to rotate. The rotating limiting roller 6 can not only block the bone outside the feeding trough 10, but also flatten the bone in the feeding trough 10, so that each bone sent out is straight, thereby ensuring the quality of the bone. When the feeder 0 moves to the outside of the silo 3 and is connected to the receiving trough 11, the rubber bones in the feeding trough 10 fall into the receiving trough 11. The rubber bones in the receiving trough 11 can either fall directly into the side push trough 13 or be received by the side push plate 8. The side push driving mechanism 9 drives the side push plate 8 to retreat, so that the rubber bones in the receiving trough 11 fall into the side push trough 13. Then the side push driving mechanism 9 drives the side push plate 8 forward, so that the side push plate 8 pushes the rubber bones in the side push trough 13 into the rubber bone wearing channel 12. Finally, the material pushing driving mechanism 29 drives the pushing rod 30 to move along the rubber bone wearing channel 12 and pushes the rubber bones in the rubber bone wearing channel 12 into the bone wearing part of the fabric through the sleeve nozzle 14, so as to realize automatic rubber bone wearing. The utility model has high efficiency in automatic rubber bone wearing, good stability in feeding the rubber bones, and is not prone to material jamming. The material limiting roller 6 can flatten the rubber bones and output them, thereby ensuring the quality of the rubber bones.

[0026] In this embodiment, the housing 1 or the bone-threading seat 2 is equipped with a clamping mechanism 15, and the clamping end of the clamping mechanism 15 is movably arranged outside the sleeve mouth 14. In actual application, after the bone-threading part of the fabric is sleeved outside the sleeve mouth 14, the clamping end of the clamping mechanism 15 clamps the bone-threading part of the fabric on the sleeve mouth 14 to ensure the stability of the bone-threading part of the fabric when threading the bone, thereby ensuring the quality of the bone-threading.

[0027] In this embodiment, the clamping mechanism 15 includes a clamping cylinder 16 installed on the housing 1 or the rubber frame seat 2 and two clamping blocks 17 respectively installed on the two output ends of the clamping cylinder 16. The socket nozzle 14 is located between the two clamping blocks 17. The clamping cylinder 16 is used to drive the two clamping blocks 17 to move closer to or away from each other.

[0028] In actual application, after the bone-penetrating portion of the cloth is sleeved outside the sleeve nozzle 14, the clamping cylinder 16 drives the two clamping blocks 17 to approach each other until the two clamping blocks 17 clamp the bone-penetrating portion of the cloth outside the sleeve nozzle 14; after completing the bone-penetrating, the clamping cylinder 16 drives the two clamping blocks 17 to move away from each other to loosen the bone-penetrating portion of the cloth, and the cloth after the bone-penetrating portion can be taken away at this time.

[0029] In this embodiment, a guide plate 18 is installed in the silo 3, and the guide plate 18 is tangentially connected to the upper side of the limiting roller 6. In practical applications, the guide plate 18 protects the limiting roller 6. When adding the rubber bone into the silo 3, the rubber bone can slide into the silo 3 along the guide plate 18, which is convenient for operators to add the rubber bone into the silo 3 and prevents the rubber bone from falling into the gap between the limiting roller 6 and the inner wall of the silo 3.

[0030] In this embodiment, an adjustment plate 19 is movably provided in the silo 3, and the moving direction of the adjustment plate 19 is parallel to the axial direction of the limiting roller 6. According to the length of the ribs, the position of the adjustment plate 19 in the silo 3 is adjusted to adjust the length of the storage space for storing the ribs in the silo 3, which is conducive to neatly placing the ribs in the silo 3.

[0031] Specifically, the adjustment plate 19 is provided with an escape groove, which provides an escape space for the inclined guide plate 18 and the material limiting pressure roller 6 .

[0032] In this embodiment, an incoming material sensor 20 is installed on the outer wall of the silo 3 . The incoming material sensor 20 is arranged corresponding to the receiving trough 11 . The incoming material sensor 20 is used to sense whether there is a plastic bone in the receiving trough 11 .

[0033] After the feeding plate 4 transports the rubber bones to the receiving trough 11, the feeding plate 4 retreats, so that the feeding trough 10 on the feeding plate 4 returns to the silo 3. At this time, the incoming material sensor 20 senses the rubber bones in the receiving trough 11 to detect whether there are rubber bones in the receiving trough 11, and feeds back the sensing results to the external control system, so that the external control system controls the feeding drive mechanism 5, the side push drive mechanism 9 and the pushing drive mechanism 29 to make corresponding actions respectively.

[0034] In this embodiment, the bottoms of the two opposite side wall plates of the silo 3 are provided with slots 21, and the slots 21 are used for the feeding plate 4 to pass through. The provision of the slots 21 makes the structure of the silo 3, the feeding plate 4 and the piercing frame seat 2 compact, plays a guiding role in the movement of the feeding plate 4, and makes the movement of the feeding plate 4 more stable and smooth.

[0035] In this embodiment, the feeding drive mechanism 5 includes a feeding cylinder 22 installed on the housing 1 and a buffer protection module 23 installed on the piston rod of the feeding cylinder 22, and the feeding plate 4 is installed on the buffer end of the buffer protection module 23. In the process of the feeding cylinder 22 driving the buffer protection module 23 to feed the rubber bone together with the feeding plate 4, when the material jamming problem occurs, the buffer protection module 23 plays a role of buffer protection to avoid the phenomenon of hard impact such as collision.

[0036] In this embodiment, the buffer protection module 23 includes a sensing cylinder 24 installed on the piston rod of the feeding cylinder 22, a mounting plate 25 installed on the piston rod of the sensing cylinder 24, a spring 26 mounted on the outside of the piston rod of the sensing cylinder 24, a material jamming sensor installed in the cylinder body of the sensing cylinder 24, and a sensing plate installed on the piston rod of the sensing cylinder 24, the sensing plate is used to trigger the material jamming sensor, the two ends of the spring 26 respectively contact the cylinder body of the sensing cylinder 24 and the mounting plate 25, the material jamming sensor is electrically connected to the feeding cylinder 22, and the feeding plate 4 is mounted on the mounting plate 25.

[0037] When the buffer protection module 23 performs buffer protection, the spring 26 is compressed, causing the piston rod of the sensing cylinder 24 to retract. When the sensing sheet triggers the material jam sensor, the material jam sensor feeds back a signal to the feeding cylinder 22, causing the feeding cylinder 22 to first drive the feeding plate 4 to reset, and then drive the feeding plate 4 to move for feeding.

[0038] In this embodiment, the bone-penetrating seat 2 includes a bottom plate 27 and a top plate 28 mounted on the top surface of the bottom plate 27, a feed plate 4 is slidably mounted on the top surface of the top plate 28, a material receiving groove 11 is mounted on the top surface of the top plate 28, a side push groove 13 and a bone-penetrating channel 12 are both mounted on the bottom plate 27, and a sleeve plate is extended from the bottom plate 27 and the top plate 28, and the sleeve plate of the bottom plate 27 and the sleeve plate of the top plate 28 are arranged opposite to each other up and down to form a sleeve mouth 14. This structural design realizes the modular assembly of the bone-penetrating seat 2, and is convenient for processing, disassembly, and maintenance.

[0039] Specifically, the rotation driving mechanism 7 may be composed of a motor, a synchronous belt and a synchronous wheel, which will not be described in detail here.

[0040] Specifically, the structure of the side push drive mechanism 9 and the structure of the material push drive mechanism 29 can be the same as that of the material feed drive mechanism 5, and will not be described in detail here.

[0041] All technical features in this embodiment can be freely combined according to actual needs.

[0042] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
