Description

Technical Field

[0001] This utility model belongs to the technical field of stuffing machines, and in particular relates to a lifting and pushing mechanism for stuffing machines. Background Technology

[0002] In modern society, the food processing industry has largely achieved automated production. A filling machine is a type of machinery used to process pastries with fillings. The filling machine has hoppers for holding pastry filling materials and outer dough materials. The filling or outer dough materials in the hoppers are supplied to the filling extrusion mechanism through a spiral conveyor at the bottom of the hoppers. In the filling extrusion mechanism, the filling is continuously processed to form a rod-shaped food embryo wrapped with filling. The rod-shaped food embryo is cut into individual pastry embryos by a cutting mechanism. The pastry embryos fall onto a conveyor belt and are transported to the next process.

[0003] Regarding the aforementioned technologies, when the raw pastry dough is cut and falls onto the conveyor belt, it inevitably impacts the conveyor belt, which can easily cause deformation of the unprocessed and unshaped raw pastry dough or even cracks in the outer skin of the raw pastry dough, thereby affecting the appearance of the pastry product.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0026] Please see Figure 1 As shown, this utility model is a lifting and pushing mechanism for a filling machine, including a filling machine body 1, a conveying mechanism 10 arranged on the outside of the filling machine body 1, and a lifting and pushing mechanism 7 arranged directly below the cutting mechanism of the filling machine body 1. The lifting and pushing mechanism 7 is used to lift the feeding section of the conveying mechanism 10 located directly below the cutting mechanism upwards; when the cutting mechanism is activated, the lifting and pushing mechanism 7 is located at the upper stop position; reducing the falling height of the pastry dough, reducing the vertical impact force, and effectively reducing the cracking and deformation of the outer skin, etc.

[0027] Specifically, such as Figure 3-4 The provided lifting and pushing mechanism 7 includes a base 21 installed on the main body 1 of the filling machine. A through hole is provided in the base 21, and a top column 210 is movably installed in the through hole. The top of the top column 210 is connected to a horizontal plate 212, and a push block 213 is provided on the horizontal plate 212. In actual use, the top column 210 can be driven to move up and down vertically in the through hole.

[0028] Specifically, to facilitate the movement of the top column 210 during use, a waist-shaped hole A211 communicating with the through hole is provided on both sides of the base 21. A connecting column 214 passing through the waist-shaped hole A211 is connected to one side of the top column 210. The connecting column 214 is connected to a fixed surface located below the base 21 by a return spring 215. It also includes a connecting plate A26. One end of the connecting plate A26 is provided with a waist-shaped hole B261 that is connected to the connecting column 214. 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. Under the action of the motor, the driving arm 28 swings back and forth with any point away from the end of the connecting rod A27 as the center. The swing angle of the driving arm 28 is 70°, that is, 35° up and down.

[0029] In order to facilitate the swinging of the drive connecting rod A27 during use, the end of the control drive arm 28 is connected to the output end of a motor;

[0030] Alternatively, the end of the drive arm 28 can be fixed to the inner wall of the filling machine body 1 via a fixed shaft 281, and a cam can be connected to the output end of a motor. A column 282 that cooperates with the cam is provided in the middle of the drive arm 28. Then, with the rotation of the motor, the drive arm 28 is driven to swing up and down around the fixed shaft 281 under the action of the cam.

[0031] Of course, in order to manually control the vertical movement of the top column 210 according to the actual situation during use, a connecting sleeve 260 is provided in the middle of the connecting plate A26; it also includes a connecting plate B220, one end of which is rotatably mounted on a fixed seat A22, which is fixed to the inner wall of the filling machine body 1; a connecting shaft is provided in the middle of the connecting plate B220 and rotatably connected to the connecting sleeve 260, and a connecting rod B23 is pivotally connected to the other end of the connecting plate B220; it also includes a fixed A fixed seat B24 is fixed on the inner wall of the main body 1 of the filling machine. A rotating sleeve 241 is rotatably installed on the fixed seat B24. 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. The end of the connecting arm B243 is pivotally connected to the connecting rod 244. The end of the connecting rod 244 is pivotally connected to the movable push rod 253, thereby realizing that when the movable push rod 253 is manually controlled to move along its axial direction, it drives the top column 210 to move up and down in the vertical direction.

[0032] Specifically, this utility model also provides two specific implementations of a drive mechanism for driving the movable push rod 253 to reciprocate along its length. One type of drive mechanism includes a fixed cylinder 25 fixed on the outer wall of the filling machine body 1. The end of the fixed cylinder 25 is connected to a screw 252 via a bearing. One end of the screw 252 is connected to a hand crank 251. The movable push rod 253 slides along the inner wall of the fixed cylinder 25, and the interior of the movable push rod 253 is provided with a threaded hole 254 that mates with the screw 252.

[0033] In Form 2, the drive mechanism includes a servo motor (255), which is coaxially connected to the screw (252) via a coupling. A displacement sensor connected to the control circuit is embedded in the outer wall of the fixed cylinder (25), and the probe of the displacement sensor is directly opposite the end of the movable push rod (253). The servo drive system, in conjunction with the displacement sensor, achieves a positioning accuracy of ±0.1mm, ensuring that the lifting height and the timing of the cutting action are precisely synchronized.

[0034] In this invention, the manual / electric dual-mode adjustment mechanism can adapt to different product specifications, with an adjustment range covering a height range of 30-150mm, meeting the production requirements of products with different thicknesses such as glutinous rice balls and mooncakes.

[0035] It also includes a counterweight roller 11 for tensioning the conveyor belt of the conveyor mechanism 10. The end of the counterweight roller 11 is connected to a swing arm, and one end of the swing arm is rotatably mounted on the outer wall of the filling machine body 1.

[0036] Connecting rod A27 and connecting rod B23 have the same structure; both include a rotating threaded sleeve, with both ends of the rotating threaded sleeve threaded to the rod body, and the end of the rod body is provided with a connector; by using the rotating threaded sleeve with a pitch of 1.5mm, a length adjustment of ±15mm can be achieved, which can eliminate millimeter-level cumulative errors caused by machining and installation.

[0037] Furthermore, the outer wall of the substrate 21 is provided with a transparent scale plate 215 covering the waist-shaped hole A211, and the outer wall of the top column 210 is provided with a color-coded transparent scale plate (215) that cooperates with the transparent scale plate 215. The transparent scale plate (215) is made of polycarbonate material and has an anti-glare coating on its surface. The color-coded strips are fluorescent silicone strips, which are equidistantly arranged along the axis of the top column (210). The combination of the polycarbonate transparent scale plate and the fluorescent markings can still be clearly identified in a dim environment. With the anti-glare coating, the reading error rate is reduced.
