[0022] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] See Figures 1-6 , this continuous winding and inserting progressive feeding device includes a bottom plate 1, a driver 2, a feeding seat component, an inserting and pushing component, and a guide plate component for placing inserts 3. The driver 2 is drivingly connected to the feeding seat component. The feeding seat component is slidably arranged on the bottom plate 1. The inserting and pushing component is elastically rotatably connected to the feeding seat component. A baffle 4 is arranged on the guide plate component. When the progressive feeding device works, the driver 2 drives the feeding seat component to move forward to drive the inserting and pushing component to move forward along the baffle 4. At this time, a certain angle is formed between the inserting and pushing component and the baffle 4 (such as Figure 2 shown), the insert feeding claw 17 abuts against the baffle 4, and the inserting and pushing component elastically rotates after passing through the baffle 4 to insert the insert 3, that is, the insert needle 18 of the insert feeding claw 17 inserts into the gap 19 between two adjacent inserts 3. At this time, the inserting and pushing component and the baffle 4 are basically parallel to each other (such as Figure 1As shown, the inserting and pushing component (insert feeding claw 17) pushes the insert 3 to move forward along the material guiding plate component to the required position, that is, the inserting and pushing component pushes the insert 3 to move one pitch (the pitch is the width of the insert 3). After the insert 3 moves to the required position, the driver 2 drives the feeding seat component and the inserting and pushing component to move backward. When the inserting and pushing component reaches the baffle 4, it is elastically rotated due to the obstruction of the baffle 4. At this time, a certain angle is formed between the inserting and pushing component and the baffle 4. After the feeding seat component and the inserting and pushing component move backward to the maximum position, the insert feeding claw 17 abuts against the baffle 4, that is, the insert feeding claw 17 stops on the baffle 4 and waits for the next feeding; the driver 2 is a cylinder. When the insert 3 moves to the required position, the piston rod of the cylinder extends to the maximum position, that is, the stroke of the cylinder. When the insert feeding claw 17 stops on the baffle 4 and waits for the next feeding, the piston rod of the cylinder retracts to the maximum position, that is, the stroke of the cylinder. That is, for each push of the insert 3, the cylinder needs to complete its stroke to achieve progressive feeding.

[0024] The material guiding plate component includes a material guiding plate 5, a pre-pressing seat 6 and a pre-pressing plate 7. The material guiding plate 5 is fixed on the bottom plate 1, the pre-pressing seat 6 is fixed on the material guiding plate 5, and the pre-pressing plate 7 is elastically rotatably connected to the pre-pressing seat 6 through a first pin 28. The pre-pressing plate 7 can rotate around the first pin 28. A placing groove 8 for placing the insert 3 is provided on the material guiding plate 5. The pre-pressing plate 7 presses the insert 3 against the placing groove 8. The inserts 3 are placed in the placing groove 8 in a whole row (the inserts 3 are manually placed into the placing groove 8). The thrust of the cylinder is greater than the frictional force between the insert 3 and the pre-pressing plate 7. Therefore, under the thrust of the inserting and pushing component (insert feeding claw 17), the insert 3 overcomes the frictional force between it and the pre-pressing plate 7 and thus moves forward to the required position. Since the whole row of inserts 3 is integrated, the inserting and pushing component pushes the whole row of inserts 3 forward; when the feeding seat component and the inserting and pushing component move backward, the insert 3 will not move backward due to the pressing force of the pre-pressing plate 7.

[0025] An elastic adjusting component is provided between the pre-pressing seat 6 and the pre-pressing plate 7. The elastic adjusting component includes a first elastic member 9 and a first adjusting member 10. The first adjusting member 10 is adjustably installed on the pre-pressing seat 6. The first elastic member 9 is arranged between the pre-pressing plate 7 and the first adjusting member 10. When the first adjusting member 10 is adjusted, it acts on the pre-pressing plate 7 through the first elastic member 9, so that the pre-pressing plate 7 will slightly rotate, and then the pressing force of the pre-pressing plate 7 on the insert 3 is adjusted; the first elastic member 9 is installed inside the pre-pressing seat 6. The first elastic member 9 is a compression spring, and the first adjusting member 10 is an adjusting nut. A threaded hole matching the adjusting nut is provided inside the pre-pressing seat 6.

[0026] One end of the pre-pressure plate 7 is provided with a handle 29. When manually inserting the insert piece 3 into the placement groove 8, it is necessary to press the handle 29 of the pre-pressure plate 7 backward so that the whole row of insert pieces 3 can smoothly pass through the placement groove 8. After stopping the whole row of insert pieces 3 at a proper position, release the handle 29 so that the pre-pressure plate 7 presses the insert piece 3 against the placement groove 8.

[0027] The feeding seat assembly includes a feeding seat 11 and a connecting piece 12. The driver 2 is drivingly connected to the connecting piece 12. The connecting piece 12 is installed on the feeding seat 11. The feeding seat 11 is slidably arranged on the bottom plate 1 through a slide rail assembly 13. The slide rail assembly 13 is a combination of a slide rail and a slider. The driver 2 pushes the feeding seat 11 forward through the connecting piece 12.

[0028] The inserting and pushing assembly includes a feeding needle seat 14 and an inserting member. The feeding needle seat 14 is rotatably connected to the feeding seat 11 through a second pin 30, and a second elastic member 15 is arranged between the feeding needle seat 14 and the feeding seat 11. The inserting member is installed on the feeding needle seat 14. The inserting and pushing assembly moves forward along the baffle 4 under the elastic force of the second elastic member 15. After the inserting and pushing assembly passes through the baffle 4, the inserting and pushing assembly elastically rotates under the elastic force of the second elastic member 15 so that the inserting member inserts into the insert piece 3. The second elastic member 15 is a tension spring, and the feeding needle seat 14 can rotate around the second pin 30 under the pulling force of the tension spring.

[0029] A second adjusting member 16 is adjustably arranged on the feeding seat 11. One end of the second adjusting member 16 abuts against the feeding needle seat 14. When the second adjusting member 16 is adjusted, it acts on the feeding needle seat 14 to adjust the angle of the feeding needle seat 14, thereby adjusting the depth of the inserting needle 18 inserted into the gap 19. The second adjusting member 16 is an adjusting screw, and a first adjusting hole 31 cooperating with the second adjusting member 16 is arranged on the feeding seat 11. The first adjusting hole 31 is a threaded hole.

[0030] The inserting member includes two inserting piece feeding claws 17 distributed up and down and an adjusting mechanism. The adjusting mechanism is installed on the feeding needle seat 14. The inserting piece feeding claws 17 are installed on the adjusting mechanism. Inserting needles 18 are arranged on the inserting piece feeding claws 17. Gaps 19 distributed up and down are arranged between adjacent insert pieces 3. When the inserting and pushing assembly inserts into the insert piece 3, the inserting needles 18 insert into the corresponding gaps 19, and the inserting needles 18 are in contact with the corresponding positions of the insert piece 3. Two inserting piece feeding claws 17 are provided. The double-claw design makes the insert piece 3 not easily deformed during the feeding process. An avoiding inclined surface 32 is arranged on one side of the inserting needle 18. When the driver 2 drives the feeding seat assembly and the inserting and pushing assembly to move backward, the inserting piece feeding claws 17 avoid the insert piece 3 through the avoiding inclined surface 32, preventing the inserting piece feeding claws 17 from driving the insert piece 3 to move backward.

[0031] The adjusting mechanism includes a third adjusting member 20 and a bracket 21. The third adjusting member 20 is rotatably mounted on the feeding needle base 14. The bracket 21 is movably arranged in the front and rear directions on the feeding needle base 14. The insert feeding claw 17 is mounted at one end of the bracket 21. The third adjusting member 20 and the bracket 21 are movably connected through an adjusting portion. When the third adjusting member 20 is adjusted, it drives the bracket 21 to move back and forth through the adjusting portion, thereby adjusting the front and rear positions of the insert feeding claw 17, and further adjusting (fine-tuning) the front and rear positions of the inserting needle 18 inserted into the placement groove 8, so as to adjust the specific delivery position of the insert 3 to adapt to inserts 3 of different model specifications (width of the insert 3) and different pitches. Different specifications can be quickly converted without replacing parts, and it is ensured that the corresponding positions of the inserting needle 18 and the insert 3 are in full contact. Because for inserts 3 of different model specifications, their front and rear positions placed in the placement groove 8 are different; the third adjusting member 20 is an adjusting screw, and a second adjusting hole 33 is provided at the other end of the bracket 21. The adjusting portion includes an external thread provided on the adjusting screw and an internal thread provided on the second adjusting hole 33, and the external thread and the internal thread cooperate with each other.

[0032] The adjusting mechanism further includes a locking block 22. Locking grooves 23 are provided on the locking block 22 and are distributed vertically. At least part of the bracket 21 is arranged on the locking grooves 23. A first fixing hole 24 is provided on the feeding needle base 14, and a second fixing hole 25 is provided on the locking block 22. A fastener (screw) passes through the first fixing hole 24 and is tightly connected to the second fixing hole 25 to fix the locking block 22 on the feeding needle base 14, thereby locking the bracket 21 on the feeding needle base 14, that is, the bracket 21 is pressed between the feeding needle base 14 and the locking block 22; if it is necessary to adjust the front and rear positions of the insert feeding claw 17, the locking block 22 needs to be removed first.

[0033] At least part of the placement groove 8 is covered by a baffle 4. An adjusting fixing hole 26 is provided on the baffle 4. The adjusting fixing hole 26 is an elongated hole. A third fixing hole 27 is provided on the guide plate 5. A fastener (screw) passes through the adjusting fixing hole 26 and is tightly connected to the third fixing hole 27 to fix the baffle 4 on the guide plate 5. The fastener can pass through the adjusting fixing hole 26 adjustably to adjust the front and rear positions of the baffle 4 on the guide plate 5, that is, adjust the position of the baffle 4 covering the placement groove 8, and further adjust the front and rear positions of the inserting needle 18 inserted into the placement groove 8 to adapt to inserts 3 of different model specifications (width of the insert 3) and different pitches.
