In the present embodiment, the work bench 1 has a rectangular frame structure having a length direction and a width direction. The first direction L1 is parallel to the longitudinal direction thereof, and a second direction L2 described below is parallel to the width direction thereof.

In other possible embodiments, the drive sprocket and the driven sprocket may be replaced with a synchronous wheel and the chain may be replaced with a synchronous belt.
As shown in fig. 1 and 4, the arc-shaped turnover part 3 includes: two arc-shaped sheets 301 and an arc-shaped rack 302 clamped between the two arc-shaped sheets 301. Also, the outer wall of the arc-shaped rack 302 having teeth exceeds the outer walls of the two arc-shaped pieces 301.
The supporting seat 2 includes: two arc-shaped supporting arm plates 201 which are opposite and arranged at intervals, and two arc-shaped sheets 301 are clamped between the two arc-shaped supporting arm plates 201. In order to reduce the rotation resistance of the arc-shaped turnover part 3 and simultaneously avoid the direct contact between the arc-shaped turnover part 3 and the inner wall of the supporting seat 2, a resistance reducing wheel 38 can be arranged between the two arc-shaped supporting arm plates 201, and the two resistance reducing wheels 38 are respectively in rolling contact with the outer walls of the two arc-shaped pieces 301. Therefore, the two arc sheets 301 of the arc-shaped turnover part 3 are respectively supported by the two drag reduction wheels 38 and are in roller contact with the drag reduction wheels 38 under the support of the drag reduction wheels 38, so that the direct contact with the inner wall of the arc-shaped groove is avoided, and the smoothness of the rotation of the arc-shaped turnover part 3 in the arc-shaped groove is ensured.
As shown in fig. 2 and 3, in order to improve the resistance reduction effect, a plurality of sets of resistance reduction wheels 38 may be provided, and the plurality of sets of resistance reduction wheels 38 are arranged in the arc-shaped groove along the circumferential direction. Thus, the arc-shaped turner 3 is lifted off by the stand without contacting the inner wall of the support base 2.
Further, a stabilizer bar 11 is arranged on the outer side of the arc-shaped supporting arm plate 201, a pressing wheel 12 extending towards the two arc-shaped pieces 301 is arranged at the upper end of the stabilizer bar 11, and the pressing wheel 12 is in rolling contact with the inner walls of the two arc-shaped pieces 301. Thus, the arc-shaped turnover part 3 is limited in the arc-shaped groove and cannot slip out of the arc-shaped groove.
In this embodiment, the arc-shaped turnover part 3 is a partial circular ring structure, and the radian thereof may be set according to actual conditions, for example, 180 degrees, which is not limited in this embodiment. Correspondingly, the radian of the arc-shaped groove of the supporting seat 2 is matched with that of the arc-shaped turnover part 3.
With continued reference to fig. 4, in order to make the floating roller 5 float, a rocker arm 13 is rotatably disposed on the inner side wall of the arc-shaped turnover part 3, and the floating roller 5 is rotatably connected with the rocker arm 13. The reset piece 7 is a spring in a stretching state, one end of the spring is connected with the rocker arm 13, and the other end of the spring is connected with the supporting seat 2. The connection point of the spring to the support base 2 is close to the fixed roller 4, so that the elastic pulling force applied to the rocker arm 13 by the spring causes the rocker arm 13 to have a tendency to rotate toward the fixed roller 4 all the time.
Thus, when raw material core rods 6 with different diameters need to be fed, the floating rollers 5 capable of floating along the circumferential direction of the arc-shaped turnover part 3 can adapt to the clamping requirements of the raw material core rods 6 with different diameters, and further the raw material core rods 6 with different diameters can be tightly clamped between the floating rollers 5 and the fixed rollers 4.
In this embodiment, to reduce the driving cost, a set of power assembly is used to drive the two arc-shaped turnover members 3. Specifically, as shown in fig. 1 and 3, the power assembly includes:
a first motor (not shown);
a driving gear 14 rotatably arranged at the first end of the working rack 1, wherein the driving gear 14 is connected with an output shaft of a first motor;
a total driven gear 15 which is rotatably arranged at the first end of the working rack 1;
a first driven gear (not shown) disposed coaxially with the total driven gear 15, the first driven gear being interposed between the two arc-shaped arm plates 201 included in the support base 2 at the first end and meshing with the arc-shaped rack 302 at the first end;
the transmission shaft 16 is rotatably arranged on the work bench 1 and crosses over the work bench 1 along the first direction L1, one end of the transmission shaft 16 is coaxially connected with the total driven gear 15, and the other end is provided with a second driven gear (not shown), which is clamped between two arc-shaped arm supporting plates 201 included in the supporting seat 2 at the second end and is meshed with the arc-shaped rack 302 at the second end.
In this embodiment, in order to convert the high-speed rotation of the first motor into the relatively low-speed rotation of the arc-shaped turnover part 3, the diameters of the first driven gear and the second driven gear are equal and smaller than the diameter of the total driven gear 15. The diameter of the first driven gear and the diameter of the second driven gear are smaller than the diameter of the total driven gear 15, so that speed reduction is realized.
In fact, the total driven gear 15, the first driven gear and the second driven gear are all arranged on the transmission shaft 16. The transmission shaft 16 crosses the working platform 1 along the first direction L1, one end of the transmission shaft, which is provided with the driven gear 15, penetrates to the outer side of the first end of the working platform 1, and then the driven gear 15 is arranged on the end part of the transmission shaft 16, which is located at the first end.
As shown in figure 1, the transmission shaft 16 has a long span length, and can be arranged in a segmented mode and comprises two sub-transmission shafts, and the joint of the two sub-transmission shafts is connected by a coupler 39 fixed on the working table frame 1.
In this embodiment, the fixed roller 4 is fixed relative to the support base 2 during operation. However, to accommodate the loading requirements of feedstock core rods 6 of different diameters, the fixed rollers 4 are configured to be movably fixed relative to the support bed 2. Specifically, the supporting seat 2 is provided with an adjusting mechanism, and the end part of the fixed roller 4 is connected with the adjusting mechanism. The pitch mechanism is used for adjusting the feeding distance of the fixed roller 4 towards the arc-shaped groove along the horizontal direction.
In order to achieve the above object, as shown in fig. 2, the adjusting mechanism includes:
the fixed block 17 is arranged at the edge of the support seat 2 positioned outside the arc-shaped groove, a horizontal channel 171 is arranged in the fixed block 17, and a limiting protrusion 172 is formed by inwards protruding the inner wall of the horizontal channel 171;
a fixing nut 40 arranged in the horizontal channel 171, wherein a bolt 18 is screwed in the fixing nut 40, and the cap body of the bolt 18 is positioned at the outer side of the fixing block 17;
a feeding member 19 disposed in the horizontal passage 171 and movable in the horizontal passage 171, an inner end of the feeding member 19 being rotatably connected to an inner end of the bolt 18, and an outer end thereof extending into the arc-shaped groove; the outer wall of the feeding piece 19 is recessed inwards to form a horizontal limiting groove 192 in a long strip shape, and the limiting protrusion 172 is embedded in the horizontal limiting groove 192;
wherein, the outer end of the feeding piece 19 is provided with a rotating shaft hole 191, and the end part of the fixed roller 4 is rotatably connected with the feeding piece 19 through the rotating shaft hole 191.
In this embodiment, the fixing nuts 40 may be two, one of which is located in the middle of the horizontal channel 171, and the other of which is located at the outer end of the horizontal channel 171, for blocking the outer end port of the horizontal channel 171. Because the cap body of the bolt 18 is exposed out of the fixing block 17, when the position of the fixing roller 4 needs to be adjusted, the cap body of the bolt 18 is screwed, the bolt 18 moves inwards or outwards in the horizontal channel 171 under the screwing action of the fixing nut 40, so that the feeding piece 19 is driven to move inwards or outwards, and the fixing roller 4 arranged at the outer end of the feeding piece 19 correspondingly moves inwards or outwards in the arc-shaped groove along the horizontal direction, so that the position adjustment of the fixing roller 4 is realized, and the clamping requirement of the raw material core rods 6 with different diameters is met.
In this embodiment, in order to enable the bolt 18 to drive the feeding member 19 to move in the horizontal channel 171 and prevent the feeding member 19 from blocking the rotation of the bolt 18, the inner end of the bolt 18 has a degree of freedom of circumferential rotation compared with the inner end of the feeding member 19, and the two are fixed in the axial direction. To achieve this connection, the inner end of the feed member 19 may be provided with a circular hole into which the inner end of the bolt 18 is inserted, and the end of the bolt 18 located within the circular hole may be provided with a stop radially outwardly.
The engagement of the stop protrusion 172 with the horizontal stop groove 192 can act to limit or assist the movement of the feeding member 19 in the horizontal channel 171. In addition, the fixed roller 4, being heavier, is provided at the outer end of the feed member 19, and will cause the inner end of the feed member 19 to have a tendency to contact the inner wall of the horizontal passage 171. Therefore, by providing the matching limit protrusion 172 and the horizontal limit groove 192, the feeding member 19 can be balanced, the feeding member 19 is prevented from contacting the inner wall of the horizontal channel 171, and the moving friction force of the feeding member 19 in the horizontal channel 171 is reduced, thereby achieving smooth movement.
