[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Example: Figure 1-11 As shown, the feeder with a single-double drive structure includes a box body 1 and a lower feed roller 2, an upper feed roller 3, a main drive mechanism 4, an auxiliary drive mechanism 5, and a transmission shaft group 6 arranged on the box body 1. The axial ends of the lower feed roller 2 are respectively connected to the main drive mechanism 4 and the transmission shaft group 6. The lower feed roller 2 is driven by the main drive mechanism 4, or by the main drive mechanism 4 and the auxiliary drive mechanism 5. The transmission shaft group 6 has a transmission shaft 601, which is rotatably connected to the box body 1 and connected to the lower feed roller 2. The transmission shaft 601 It rotates synchronously with the lower feed roller 2, and one end of the transmission shaft 601 facing away from the lower feed roller 2 is exposed from the box body 1. A transmission hole 602 is provided at the end of the transmission shaft 601 exposed from the box body 1. The transmission hole 602 extends axially along the lower feed roller 2. The auxiliary drive mechanism 5 is detachably fixedly connected to the transmission shaft 601 at the transmission hole 602. The upper feed roller 3 is arranged on one side of the lower feed roller 2 and is spaced from the lower feed roller 2 to form a feeding gap (not marked in the figure). The upper feed roller 3 can move relative to the lower feed roller 2 to adjust the feeding gap.

[0031] When the material to be conveyed is heavier or needs to be conveyed quickly, the auxiliary drive mechanism 5 is assembled on the transmission shaft 601. At this time, the lower feed roller 2 is driven by the main drive mechanism 4 and the auxiliary drive mechanism 5 at the same time. The lower feed roller 2 has a stronger conveying capacity, so that the feeder with a single or double drive structure can convey heavier materials or convey materials quickly; when the material to be conveyed is lighter or needs to be conveyed slowly, the auxiliary drive mechanism 5 is detached from the transmission shaft 601. At this time, the lower feed roller 2 is driven by the main drive mechanism 4, and the conveying capacity of the lower feed roller 2 is reduced, so that the feeder with a single or double drive structure can convey lighter materials or convey materials slowly, and it is flexible and versatile to use.

[0032] In summary, the present embodiment provides a feeder with a single-double drive structure to solve the problem that the lower feed roller of the existing punch feeder is driven by a single drive mechanism and cannot meet the conveying power requirement. The structure is mainly achieved by configuring a transmission shaft group 6 at the end of the lower feed roller 2 away from the main drive mechanism 4. The transmission shaft group 6 has a transmission shaft 601 rotatably connected to the box body 1. The transmission shaft 601 is connected to the lower feed roller 2 and has a transmission hole 602. The transmission hole 602 is used for detachable fixed connection with the auxiliary drive mechanism 5, so that the feeder with a single-double drive structure can increase the driving mechanism to increase the driving power when the power is insufficient, and when the power is sufficient, the auxiliary drive mechanism 5 can be detached to reduce the driving power, thereby realizing the single drive (driven only by the main drive mechanism 4) and double drive (driven by the main drive mechanism 4 and the auxiliary drive mechanism 5) of the lower feed roller 2, with strong driving force and flexible use.

[0033] In the embodiment of the present invention, the housing 1 has a socket (not shown) for the lower feed roller 2 to pass through, and the transmission shaft assembly 6 has a bearing 603, which is passed through the transmission shaft 601 and embedded in the socket. The above arrangement enables the transmission shaft 601 to rotate stably and smoothly by configuring the socket on the housing 1 and configuring the bearing 603 embedded in the socket on the transmission shaft 601.

[0034] In the embodiment of the present invention, the axial direction of the transmission shaft 601 is defined as the front-to-back direction, and the transmission shaft assembly 6 has two limit rings 604, which are arranged on the transmission shaft 601 to cooperate with the bearing 603 to limit the forward and backward movement relative to the transmission shaft 601, and the limit rings 604 are detachably fixedly connected to the housing 1. The above arrangement makes the bearing 603 assembly stable by configuring two limit rings 604 on the transmission shaft 601 to limit the forward and backward movement of the bearing 603.

[0035] In the embodiment of the present invention, one of the two limiting rings 604 is defined as a rear limiting ring 605, and the other limiting ring 604 is defined as a front limiting ring 606. The rear limiting ring 605 is located at the rear, and the front limiting ring 606 is located at the front. The housing 1 is provided with a front limiting hole (not shown in the figure) for the front limiting ring 606 to be inserted. The front limiting ring 606 has a front stopper 607 that extends backward into the insertion hole and stops on the bearing 603. The above arrangement allows the front limiting ring 606 to be stably assembled with the housing 1 by arranging the front limiting hole for the front limiting ring 606 to be inserted on the housing 1, and allows the bearing 603 to be stably assembled by arranging the front limiting ring 606 with the front limiting hole and the front stopper 607 that extends into the insertion hole and stops on the bearing 603.

[0036] In the embodiment of the present invention, the transmission shaft 601 has a rear shoulder 608, which cooperates with the front limit ring 606 to limit the forward and backward movement of the bearing 603. The above arrangement makes the bearing 603 stable by configuring the rear shoulder 608 on the transmission shaft 601 to cooperate with the front limit ring 606 to limit the forward and backward movement of the bearing 603.

[0037] In the embodiment of the present invention, the front limit ring 606 and the transmission shaft 601 are radially spaced to form a limit gap (not shown in the figure), and the transmission shaft 601 is provided with a limit ring 609 embedded in the limit gap. The limit ring 609 can be elastically deformed in the radial direction of the transmission shaft 601. The limit ring 609 has an outer abutment piece 610, an inner abutment piece 611 and a connecting piece 612. The outer abutment piece 610 and the inner abutment piece 611 are spaced in the radial direction of the transmission shaft 601. The connecting piece 612 connects the outer abutment piece 610 and the inner abutment piece 611. The outer abutment piece 610 abuts on the front limit ring 606, and the inner abutment piece 611 abuts on the transmission shaft 601 and tilts backward from the outside to the inside. The above arrangement makes the transmission shaft 601 stable to assemble by arranging the limit ring 609 between the transmission shaft 601 and the front limit ring 606.

[0038] In the embodiment of the present invention, the lower feed roller 2 has a secondary mounting hole 201 for inserting the transmission shaft 601, the transmission shaft 601 and the hole wall of the secondary mounting hole 201 are spaced apart to form a secondary mounting gap (not shown in the figure), and a secondary abutment 614 is penetrated on the transmission shaft 601, and the secondary abutment 614 has a secondary inner stop ring 615 embedded in the secondary mounting gap and a secondary outer stop ring 616 abutting against the hole edge of the secondary mounting hole 201. The above arrangement is provided on the lower feed roller 2 to provide the secondary mounting hole 201 for inserting the transmission shaft 601, and on the transmission shaft 601 to provide the secondary abutment 614 at least partially embedded in the secondary mounting gap, so that the transmission shaft 601 and the lower feed roller 2 are stably assembled.

[0039] In the embodiment of the present invention, two hydraulic tension sleeves 8 are provided on the lower feed roller 2, and the two hydraulic tension sleeves 8 are spaced apart in the axial direction of the lower feed roller 2. The above arrangement enables the lower feed roller 2 to have a good load-bearing capacity and a good feeding effect by configuring two hydraulic tension sleeves 8 on the lower feed roller 2 and the two hydraulic tension sleeves 8 are spaced apart in the axial direction of the lower feed roller 2.

[0040] In the embodiment of the present invention, the main drive mechanism 4 is arranged on the box body 1 and has a main motor 401 drivingly connected to the lower feed roller 2. The output shaft of the main motor 401 is defined as a main output shaft 402. The lower feed roller 2 has a main mounting hole 202 for inserting the main output shaft 402. The main output shaft 402 is spaced apart from the hole wall of the main mounting hole 202 to form a main mounting gap (not marked in the figure). The main output shaft 402 is penetrated by a main abutment 403. The main abutment 403 has a main inner stop ring 404 embedded in the main mounting gap and a main outer stop ring 405 abutting against the edge of the main mounting hole 202. The above arrangement makes the assembly of the lower feed roller 2 and the main output shaft 402 stable.

[0041] In the embodiment of the present invention, a shielding cover 9 is provided on the box body 1, and the shielding cover 9 is detachably fixedly connected to the box body 1 and is used to cover the end of the transmission shaft 601 exposed from the box body 1. The above arrangement prevents the transmission hole 602 from being exposed when the feeder with a single-double drive structure is driven alone by configuring the shielding cover 9 on the box body 1 to cover the end of the transmission shaft 601 exposed from the box body 1.

[0042] In the embodiment of the present invention, the auxiliary drive mechanism 5 is arranged on the box body 1 and has an auxiliary motor 501 transmission-connected to the transmission shaft 601 , and the output shaft of the auxiliary motor 501 is defined as an auxiliary output shaft 502 , which is plug-fitted with the transmission hole 602 .

Among them, when the upper feed roller 3 moves along the upper transmission member 10 to move closer to or away from the lower feed roller 2, the feeding distance between the upper feed roller 2 and the lower feed roller 3 is adjusted, so that the feeder with a single and double drive structure switches between the feeding state and the relaxation state. The above-mentioned setting is achieved by configuring a lower transmission part 615 on the transmission shaft 601, configuring an upper transmission member 10 meshing with the lower transmission part 615 on the box body 1, and configuring an upper feeding roller 3 sliding with the lower transmission part 615 on the adjustment seat 11, so as to achieve feeding gap adjustment while avoiding separation collision between the lower transmission part 615 and the upper transmission member 10 when adjusting the gap.
