Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of stuffing machines, and particularly relates to a lifting and pushing mechanism for a stuffing machine. Background Art
[0002] In the modern food processing industry, most production processes have been automated. A stuffing machine is a machine used to process pastry foods with fillings. The stuffing machine is equipped with hoppers for accommodating pastry filling materials and outer skin materials respectively. The filling materials or outer skin materials in the hoppers are supplied to the stuffing extrusion mechanism through the screw conveyor mechanism at the bottom of the hoppers. In this stuffing extrusion mechanism, a rod-shaped food blank wrapped with filling is continuously processed. The rod-shaped food blank is cut into individual pastry blanks by a cutting mechanism, and the pastry blanks fall onto a conveyor belt and are transported to the next process.
[0003] Regarding the above related technologies, the inventor found that during the process of the pastry blank falling onto the conveyor belt after being cut, it is inevitable that an impact occurs between the pastry blank and the conveyor belt, which is likely to cause the unprocessed and unfixed pastry blank to deform or even cause cracks in the outer skin of the pastry blank, thus affecting the appearance of the pastry.

[0026] Please refer to Figure 1 As shown, the present invention is a lifting and pushing mechanism for a stuffing machine, including a stuffing machine main body 1, a conveying mechanism 10 is arranged outside the stuffing machine main body 1, and a lifting and pushing mechanism 7 is further arranged directly below the cutting mechanism of the stuffing machine main body 1. The lifting and pushing mechanism 7 is used to lift the feeding section of the conveying mechanism 10 directly below the cutting mechanism upward; when the cutting mechanism operates, the lifting and pushing mechanism 7 is at the upper dead center position; reducing the dropping height of the pastry embryo, reducing the vertical impact force, and effectively reducing the cracking and deformation of the outer skin, etc.
[0027] Specifically, as Figure 3-4 shown, the provided lifting and pushing mechanism 7 includes a base body 21 installed on the stuffing machine main body 1. A through hole is arranged in the base body 21, and a top column 210 is movably arranged in the through hole. The top of the top column 210 is connected to a cross plate 212, and a push block 213 is arranged on the cross plate 212. In actual use, the top column 210 can be driven to move up and down in the through hole.
[0028] Specifically, in order to facilitate driving the movement of the top column 210 during use, waist-shaped holes A211 communicating with the through hole are arranged on both sides of the base body 21. One side of the top column 210 is connected with a connecting column 214 passing through a waist-shaped hole A211. The connecting column 214 is connected to a fixed surface below the base body 21 through a return spring 215; a connecting plate A26 is also included. One end of the connecting plate A26 is provided with a waist-shaped hole B261 for mating connection with the connecting column 214, and the other end is pivotally connected to a connecting rod A27. The end of the connecting rod A27 is pivotally connected to a driving arm 28. The driving arm 28 makes a reciprocating swing around any point at its end away from the connecting rod A27 under the action of a motor; and the swing angle of the driving arm 28 is 70°, that is, 35° up and down respectively.
[0029] When in use, in order to conveniently drive the swing of the connecting rod A27, the end of the control driving arm 28 is connected to the output end of a motor;
[0030] Alternatively, the end of the driving arm 28 is fixed to the inner wall of the stuffing machine main body 1 through a fixed shaft 281, a cam is connected to the output end of a motor, and a cylinder 282 matching the cam is arranged in the middle of the driving arm 28. Then, with the rotation of the motor, under the action of the cam, the driving arm 28 swings up and down around the fixed shaft 281.
[0031] Certainly, when in use, in order to manually control the up and down movement of the ejector pin 210 in the vertical direction according to actual conditions, a connecting sleeve 260 is arranged in the middle of the connecting plate A26; further includes a connecting plate B220, one end of the connecting plate B220 is rotatably installed on a fixed seat A22, and the fixed seat A22 is fixed on the inner wall of the stuffing machine main body 1; a connecting shaft rotatably connected to the connecting sleeve 260 is arranged in the middle of the connecting plate B220, and a connecting rod B23 is pivotally connected to the other end of the connecting plate B220; further includes a fixed seat B24 fixed on the inner wall of the stuffing machine main body 1, a rotating sleeve 241 is rotatably installed on the fixed seat B24, and a connecting arm A242 and a connecting arm B243 are connected to the rotating sleeve 241; the connecting arm A242 is pivotally connected to one end of the connecting rod B23, and the end of the connecting arm B243 is pivotally connected to a connecting rod 244, and the end of the connecting rod 244 is pivotally connected to a movable push rod 253. Thus, when manually controlling the movable push rod 253 in its axial direction, the ejector pin 210 is driven to move up and down in the vertical direction.
[0032] Specifically, the present invention also has two specific implementation forms of driving mechanisms for driving the movable push rod 253 to reciprocate in its length direction. One form of the driving mechanism includes a fixed cylinder 25 fixed on the outer wall of the stuffing machine main body 1, and a screw rod 252 is connected to the end of the fixed cylinder 25 through a bearing; a hand crank 251 is connected to one end of the screw rod 252; the movable push rod 253 slides along the inner wall of the fixed cylinder 25, and a threaded hole 254 matching the screw rod 252 is arranged inside the movable push rod 253.
[0033] In the second form, the driving mechanism includes a servo motor (255), which is coaxially connected to the screw rod (252) through a coupling. A displacement sensor connected to the control circuit is embedded on the outer wall of the fixed cylinder (25), and the probe of this displacement sensor faces the end of the movable push rod (253); the servo drive system cooperates with the displacement sensor to achieve a positioning accuracy of ±0.1 mm, ensuring the precise synchronization of the jacking height and the cutting action timing.
[0034] In the present invention, the manual / electric dual-mode adjustment mechanism can adapt to different product specification requirements, and the adjustment range covers the height range of 30 - 150 mm, meeting the production requirements of different thickness products such as tangyuan and mooncakes.
[0035] It further includes a counterweight roller 11 for tensioning the conveyor belt of the conveying mechanism 10. The end of the counterweight roller 11 is connected to a swing arm, and one end of the swing arm is rotatably installed on the outer wall of the stuffing machine main body 1.
[0036] The connecting rod A 27 and the connecting rod B 23 have the same structure; both include a rotating threaded sleeve. The two ends of the rotating threaded sleeve are respectively threaded with the rod body, and a connecting head is provided at the end of the rod body; by setting the rotating threaded sleeve with a pitch of 1.5 mm, a length adjustment of ±15 mm is achieved, which can eliminate the millimeter-level cumulative error caused by machining and installation.
[0037] Furthermore, a transparent scale plate 215 covering the waist-shaped hole A 211 is provided on the outer wall of the base body 21. A color marking is provided on the outer wall of the top column 210 and is matched with the transparent scale plate 215. The transparent scale plate (215) is made of polycarbonate material and is provided with an anti-glare coating on its surface; the color marking strip is a fluorescent silica gel strip and is arranged at equal intervals along the axial direction of the top column (210); the combination of the polycarbonate transparent scale plate and the fluorescent marking can still be clearly identified in a dim environment. With the anti-glare coating, the reading error rate is reduced.
