DETAILED DESCRIPTION

[0013] See also Figure 1-Figure 6The invention discloses a round steamed bun merging machine, characterized in that it comprises: an auxiliary constant speed blanking belt mechanism A, an auxiliary constant speed transition belt mechanism B, an auxiliary variable speed sorting belt mechanism C, a main constant speed blanking belt mechanism D, a main constant speed transition belt mechanism E and a main climbing belt mechanism F. The auxiliary constant speed blanking belt mechanism A is arranged in parallel with the main constant speed blanking belt mechanism D, and the entrances of the two are aligned; the outlet of the auxiliary constant speed transition belt mechanism B is linearly connected with the entrance of the auxiliary variable speed sorting belt mechanism C, and the side of the entrance end of the auxiliary constant speed transition belt mechanism B is perpendicular to the outlet of the auxiliary constant speed blanking belt mechanism A; the main constant speed blanking belt mechanism D, the main constant speed transition belt mechanism E and the main climbing belt mechanism F are linearly connected in sequence, and the outlet end of the main climbing belt mechanism F is higher than the inlet end; the outlet of the auxiliary variable speed sorting belt mechanism C is perpendicular to the middle side of the main constant speed transition belt mechanism E.

[0014] The main road constant speed transition belt mechanism E and the main road climbing belt mechanism F have the same structure as the auxiliary road constant speed transition belt mechanism B; the auxiliary road variable speed sequencing belt mechanism C has the same structure as the auxiliary road constant speed blanking belt mechanism A.

[0015] The auxiliary track constant speed transition belt mechanism B comprises: a belt support plate 5, a belt 6, a corner shaft 7, a plastic bearing 8, a driven roller shaft 11, a side plate 14, a bearing seat 15, a support rod 19, a driving roller shaft 20, a driving chain 21, a driving sprocket 22 and a tensioning roller 27. The two parallel side plates 14 are fixed on the frame 41. The top of the two side plates 14 is provided with a belt support plate 5. The two ends of the belt support plate 5 are respectively connected to a corner shaft 7 for rotation. The drive roller 20 is rotatably installed between the lower parts of the two side plates 14. A driven roller shaft 20 is provided, and a driven roller shaft 11 is installed next to the driving roller shaft 20. Both ends of the driven roller shaft 11 pass through long holes arranged at the lower part of two side plates 14, and there are tensioning devices at both ends of the driven roller shaft 11; the inner side of the belt 6 is wrapped around the two corner shafts 7 and the driving roller shaft 20, and the outer side of the belt 6 also bypasses the tensioning roller 27; one end of the driving roller shaft 20 is connected to the output shaft of the motor 42 installed on the frame through a chain transmission mechanism composed of two driving sprockets 22 and a driving chain 21.

[0016] The tensioning device includes a tensioning block 12 and a tensioning bolt 13. A tensioning block 12 is fixed on the outer side of each side plate 14. A screw hole is provided on the tensioning block 12 and a tensioning bolt 13 is installed. The head end of the tensioning bolt 13 is abutted or rotationally connected with the two ends of the driven roller shaft 11.

[0017] The auxiliary track constant speed material dropping belt mechanism A adds a feeder P and a feeder transmission mechanism on the basis of the auxiliary track constant speed transition belt mechanism B, and the motor 42 is connected to the feeder P through the feeder transmission mechanism.

[0018] The structure of the feeder P is as follows: a pulley bracket 1 is fixedly installed on both sides of the belt support plate 5, two O-type pulleys 3 are rotatably installed at both ends of each pulley bracket 1, and multiple O-type belts 4 are wrapped around the two O-type pulleys 3 on the same side; the bottom end of the axis of an O-type pulley 3 on the same side is connected to the output shaft of the motor 42 through the feeder transmission mechanism, and the O-type pulleys 3 on both sides rotate in opposite directions.

[0019] The feeder transmission mechanism includes a feeder transmission short shaft spline 23, a feeder chain 9, a feeder sprocket 10, a bearing seat 15, a bevel gear 17, a feeder sprocket shaft 24, a sprocket bearing seat 25 and a sprocket set fixing plate 26, and the sprocket set fixing plate 26 is installed under the belt support plate 5; the bearing seat 15 is installed on the outer side of the side plate 14 on one side, and the bevel gear transmission shaft is rotatably installed in the bearing seat 15, and the lower end of the bevel gear transmission shaft is connected to the drive roller shaft 20 through a pair of bevel gears 17 that mesh with each other. The other end is transmission connected, and the upper end of the bevel gear transmission shaft is transmission connected to a sprocket group consisting of six sprockets installed on the sprocket group fixing plate 26 through a feeder sprocket 10 and a feeder chain 9. The six sprockets are respectively installed on the sprocket group fixing plate 26 through a feeder sprocket shaft 24 and a sprocket bearing seat 25; the top ends of the shafts of the two sprockets in the sprocket group extend above the belt support plate 5, and are respectively connected to the bottom end of an O-type pulley 3 shaft on one side through a feeder transmission short shaft spline 23.

[0020] The two feeder sprocket shafts 24 connected to the bottom ends of the O-type pulley 3 shafts in the sprocket group can be moved in a vertical direction along the belt running direction to adjust the spacing of the O-type pulleys 3 on both sides through a spacing adjustment mechanism to achieve the adjustment of the clamping width of the feeder; the sprocket bearing seat of a feeder sprocket shaft 24 with adjustable spacing can be moved and adjusted along the belt running direction to compensate for the tightness of the chain when the width of the feeder is adjusted.

[0021] A first photoelectric detection switch K1 is installed in the middle of the outlet end of the upper side shield 34 of the feeder of the auxiliary speed-changing sorting belt mechanism C through the top side detection bracket 35. A C-track straightening baffle 36 is fixedly connected to the outlet end of the pulley bracket 1 of the feeder of the auxiliary speed-changing sorting belt mechanism C through an indirect fixing plate. The C-track straightening baffle 36 is fixedly installed at the belt outlet of the auxiliary speed-changing sorting belt mechanism C, and the height is 30mm-40mm away from the horizontal plane of the belt to ensure that it can slightly touch the dough embryo. When the dough embryo enters the belt of the main road constant speed transition belt mechanism E from the belt of the auxiliary speed-changing sorting belt mechanism C at high speed, in order to avoid serious slippage of the dough embryo in place, the C-track straightening baffle 36 is specially used for adjustment. During the transportation process, the steamed bun dough embryo is just sent out from the belt outlet of the auxiliary speed-changing sorting belt mechanism C, and the top is touched by the C-track straightening baffle 36, which slows down the speed to a certain extent. When it enters the belt of the main road constant speed transition belt mechanism E again, the slippage phenomenon can be effectively reduced. A side plate detection bracket 37 is fixed on the upper side of the belt support plate 5 of the main road constant speed transition belt mechanism E corresponding to the outlet end of the feeder of the auxiliary road variable speed sorting belt mechanism C. A second photoelectric detection switch K2 is installed at the end of the side plate detection bracket 37 adjacent to the main road constant speed blanking belt mechanism D, and a third photoelectric detection switch K3 is installed at the end of the side plate detection bracket 37 adjacent to the main road climbing belt mechanism F. A side support seat 40 is fixed on the side of the belt support plate 5 on one side of the belt 6 of the main road climbing belt mechanism F. The top end of the side support seat 40 is hinged to one side of a climbing upper pressure plate 38 through a hinge 39. The climbing upper pressure plate 38 can rotate around the hinge 39, thereby realizing the rapid opening and closing of the climbing upper pressure plate 38 relative to the belt 6 of the main road climbing belt mechanism F. During normal operation, the upper pressing plate 38 is flat, and a gap (usually 30mm-40mm) is left between the belt 6 for the dough to pass through. During the process of being conveyed by the belt, the dough will be rubbed between the belt and the upper pressing plate 38. When a failure occurs during the climbing process and dough is blocked, the upper pressing plate 38 can be lifted up for easy cleaning.

[0022] Vertical side plates 32 are fixed on the belt support plates 5 on both sides of the belt 6; corner shaft guards 30 are installed on the outside of each corner shaft 7. The corner shaft guards 30 are installed in the form of groove buckles on the fastening bolt heads on both sides of the corner shaft 7 at both ends of the auxiliary track constant speed blanking belt mechanism A, the auxiliary track constant speed transition belt mechanism B, and the main track constant speed blanking belt mechanism D. The A track straightening baffle 31 is fastened to the belt support plate 5 of the auxiliary track constant speed blanking belt mechanism A by bolts. The A track straightening baffle 31 is to prevent the dough embryos that fall quickly onto the belt from rolling and slipping in place due to a sudden change in speed direction. When the dough falls, the A track straightening baffle 31 is adjusted so that the dough falls to the belt and slightly hits the A track straightening baffle 31 before rolling onto the belt, which can effectively adjust the state of the dough embryos entering the belt, which has been verified to be effective and feasible in production. The side plates 32 of different lengths are close to both sides of the belt on each belt support plate 5 of the merging machine and are fastened with bolts. The feeder side shield 33 and the feeder upper shield 34 are fastened to the feeder P by bolts. The top detection bracket 35 is fastened to the C-structured feeder pulley bracket 1 by bolts to fix the first photoelectric detection switch K1.

[0023] Working process of the present invention:

[0024] During the dynamic operation of the auxiliary constant speed blanking belt mechanism A, the motor 42 equipped with a reducer transmits power to the drive roller 20 through chain transmission. On the one hand, the drive roller 20 directly drives the belt 6 to operate. On the other hand, the drive roller 20 first transmits power to the two feeder drive short shaft splines 23 through a set of bevel gears 17 and the feeder sprocket transmission mechanism, and then transmits power to the O-belt 4 through the spline connection between the O-belt pulley 3 and the feeder drive short shaft splines 23. The belt 6 and the O-belt 4 have the same running direction and the same running speed, and both run at a constant speed.

[0025] During the dynamic operation of the auxiliary track constant speed transition belt mechanism B, compared with the auxiliary track constant speed blanking belt mechanism A, only the belt operation is normal operation, and the other movement modes are exactly the same as the auxiliary track constant speed blanking belt mechanism A. The belt operates at a constant speed.

[0026] The auxiliary track speed-changing sorting belt mechanism C is exactly the same as the auxiliary track constant-speed blanking belt mechanism A during dynamic operation, but the motor of the auxiliary track speed-changing sorting belt mechanism C uses a servo speed-changing motor, which can complete speed-changing operation in a short time.

[0027] During the dynamic operation, the main track constant speed blanking belt mechanism D is exactly the same as the auxiliary track constant speed transition belt mechanism B, and the belt runs at a constant speed.

[0028] During dynamic operation, the main track constant speed transition belt mechanism E and the main track climbing belt mechanism F are exactly the same as the auxiliary track constant speed transition belt mechanism B, and the belts run at constant speed.

[0029] In summary, the belt 6 and O-belt 4 of the auxiliary road constant speed blanking belt mechanism A, the auxiliary road constant speed transition belt mechanism B, the main road constant speed blanking belt mechanism D, the main road constant speed transition belt mechanism E and the main road climbing belt mechanism F are all in constant speed operation state during dynamic operation, and the belt 6 and O-belt 4 of the auxiliary road variable speed sorting belt mechanism C can perform variable speed operation in a short time under the control of the servo drive motor during dynamic operation.

[0030] Under normal production conditions, the raw dough for round steamed buns on the two round steamed bun production lines rolls down onto the belts of the auxiliary track constant speed blanking belt mechanism A and the main track constant speed blanking belt mechanism D, and the belts of the auxiliary track constant speed blanking belt mechanism A and the main track constant speed blanking belt mechanism D run at a low speed.

[0031] The connection line of the main road constant speed blanking belt mechanism D, the main road constant speed transition belt mechanism E and the main road climbing belt mechanism F is the main road conveying route. The conveying process is:

[0032] The raw dough for round steamed buns is transported by the belt of the main track constant speed blanking belt mechanism D, and smoothly transitions to the belt of the main track constant speed transition belt mechanism E under the medium speed operation state. As the speed increases, the spacing of the raw dough for round steamed buns is stretched larger on the belt of the main track constant speed transition belt mechanism E. The raw dough for round steamed buns is transported by the belt of the main track constant speed transition belt mechanism E, first passes through the second photoelectric detection switch K2 on the side of the input end of the main track constant speed transition belt mechanism E, then passes through the second photoelectric detection switch K3, and is then transported to the belt entrance of the main track climbing belt mechanism F. Since the climbing upper pressing plate 38 on the main track climbing belt mechanism F is stationary (parallel to the belt, but there is a gap of 30-40mm between the belt and the belt), and the gap between the climbing upper pressing plate 38 and the high-speed running belt of the main track climbing belt mechanism F is small, the raw dough for round steamed buns will be transported by the belt along the running direction, and will be rubbed and kneaded by the climbing upper pressing plate 38 during the transportation process.

[0033] The connection line of the auxiliary track constant speed blanking belt mechanism A, the auxiliary track constant speed transition belt mechanism B and the auxiliary track variable speed sorting belt mechanism C is the auxiliary track conveying route, and its conveying process is:

[0034] The raw dough for round steamed buns is transported by the belt of the auxiliary track constant speed blanking belt mechanism A, and is clamped by the O-belts 4 on both sides of its feeder P, and smoothly transitions to the belt of the auxiliary track constant speed transition belt mechanism B which also runs at a low speed, and then is transported by the belt of the auxiliary track constant speed transition belt mechanism B to the belt of the auxiliary track variable speed sorting belt mechanism C which runs at a variable speed.

[0035] The merging process of the main transport route and the auxiliary transport route:

[0036] The belt of the main road constant speed blanking belt mechanism D on the main road runs at a low speed and a normal speed, the belt of the main road constant speed transition belt mechanism E runs at a medium speed and a normal speed, and the belt of the main road climbing belt mechanism F runs at a high speed and a normal speed, and the spacing of the round steamed bun dough embryos on the three sections of the main road belt is gradually pulled apart. The belt of the auxiliary road constant speed blanking belt mechanism A on the auxiliary road runs at a low speed and a normal speed, the belt of the auxiliary road constant speed transition belt mechanism B runs at a low speed and a normal speed, and the belt of the auxiliary road variable speed sorting belt mechanism C runs at a variable speed and a high speed. When the round steamed bun dough embryos on the main road pass through the second photoelectric detection switch K2, the belt of the auxiliary road variable speed sorting belt mechanism C stops running to prevent steamed buns on the auxiliary road from entering the main road. When the round steamed bun dough embryos on the main road pass through the third photoelectric detection switch K3 again, and the next steamed bun on the main road does not pass through the second photoelectric detection switch K2, the C structure belt runs, and the steamed buns on the auxiliary road are allowed to enter the main road. When the steamed buns on the auxiliary road are prohibited from entering the main road, the steamed buns on the auxiliary road need to be transported to the first photoelectric switch K1 before stopping and waiting, so as to save time for the steamed buns on the auxiliary road to enter the main road next time.
