Description

Technical fields:

[0001] This utility model relates to the technical field of pastry powder sieving and feeding facilities, and more specifically to a continuous feeding device for a pastry premixed powder sieving equipment. Background technology:

[0002] Sieving flour is a crucial step in baking and Chinese pastry making. Its core function is to separate impurities and clumps from powdered materials (such as flour, powdered sugar, and cocoa powder) using a sieve, resulting in a finer, more uniform powder and improved texture and mouthfeel. Currently, vibrating sieves are mainly used to sieve flour and other powdered materials. These sieves have an inlet at the top, and flour is currently poured manually into the inlet. To prevent flour from accumulating in the middle of the sieve, multiple small feedings are used. However, this manual operation is labor-intensive. Therefore, some have proposed using screw conveyors for feeding. This necessitates the design of a suitable screw conveyor. However, screw conveyors typically have an upward-opening hopper, requiring manual pouring of bagged flour, which is also laborious. Therefore, the design of the screw conveyor should incorporate a structure that allows for easier and more efficient flour pouring. Utility Model Content:

[0019] Example: See Figures 1 to 3 As shown, a continuous feeding device for a pastry premix powder sieving equipment includes a feeding hopper 1 set on the ground. An inclined lifting conveying pipe 2 is inserted into the left side of the feeding hopper 1. The lower part of the lifting conveying pipe 2 is formed with a feeding port that communicates with the inner cavity of the feeding hopper 1. A rotating shaft and a spiral conveying blade are inserted into the lifting conveying pipe 2. The spiral conveying blade is fixedly connected to the rotating shaft with a sleeve. The upper end of the rotating shaft is fixedly connected to the rotating shaft of the lifting motor 3 through a coupling. The lifting motor 3 is fixedly connected to the top of the lifting conveying pipe 2. An output bend 4 is fixedly connected to the upper part of the lifting conveying pipe 2. A conical protective cover 41 is formed at the lower end of the output bend 4.

[0020] An inclined mounting plane 11 is formed on the upper right side of the feeding hopper 1. A pusher frame 5 is fixedly connected to the mounting plane 11. The pusher frame 5 includes two inclined side support rods 51. The upper end of the side support rods 51 extends out of the left side wall of the feeding hopper 1 and is fixedly connected to a longitudinal top beam 53. The longitudinal top beam 53 is located above the middle of the lifting conveying pipe 2 and is fixedly connected to a support frame 6. The lower end of the side support rods 51 extends out of the right side wall of the feeding hopper 1 and is fixedly connected to a transverse bottom beam 54. The left end of the transverse bottom beam 54 is fixedly connected to the right side wall of the feeding hopper 1. Several longitudinal rollers distributed along the side support rods 51 are inserted and fixed between the side support rods 51. Roller sleeves 52 are inserted on the rollers. A feeding inlet is provided between the roller sleeves 52. The feeding inlet is located in the middle of the pusher frame 5 and directly above the hopper cavity of the feeding hopper 1.

[0021] The lower end face of the horizontal bottom beam 54 is flush with the bottom face of the feed hopper 1; a triangular reinforcing block 55 is fixedly connected between the horizontal bottom beam 54 and the side support rod 51.

[0022] The rollers are linearly and evenly distributed between the side support rods 51. The three sets of rollers are not installed in the middle of the side support rods 51. The feeding inlet is formed by the side support rods 51 and the roller sleeve 52. The feeding inlet can be formed without installing the three sets of rollers.

[0023] The support frame 6 includes two columns 61 distributed on the front and rear sides of the lifting and conveying pipe 2. The upper end of the column 61 is fixed to the longitudinal top beam 53, and the lower end is inserted with a longitudinal axle 63. The two ends of the axle 63 extend out of the column 61 and are fitted with wheels 64. The lower end of the outer wall of the wheel 64 is flush with the lower end of the feed hopper 1. A longitudinal support beam 62 is fixedly connected between the columns 61. The longitudinal support beam 62 abuts against the outer wall of the lower side of the lifting and conveying pipe 2. A transverse support beam 65 is fixed to the right side wall of the column 61. The right end of the transverse support beam 65 is fixed to the feed hopper 1. The support frame 6 can support the upper end of the pushing frame 5 and the lifting and conveying pipe 2 at the same time.

[0024] In addition, there are other functions, such as lifting the roller sleeve 52 at the lower end of the hand-held pusher 5, so that the wheel 64 can be used as a fulcrum to lift the feed hopper 1 off the ground, and then push the pusher 5. With the action of the wheel 64, it is convenient to move the feeding device.

[0025] The pusher rack 5 is equipped with an inclined material-carrying slide plate 7. The material-carrying slide plate 7 includes a support plate 71 that abuts against the roller sleeve 52. A lower baffle 711 perpendicular to the support plate 71 is formed on the lower side of the support plate 71. A feeding opening 712 corresponding to the feeding inlet is formed in the middle of the lower baffle 711. Side baffles 72 are fixed on both sides of the support plate 71 and the lower baffle 711 respectively. The addition of the material-carrying slide plate 7 allows bagged flour to be placed on the material-carrying slide plate 7.

[0026] Steel wire ropes 8 are fixed to the front and rear ends of the upper part of the material-carrying slide plate 7, and several pulleys 9 are fixedly connected to the longitudinal top beam 53. The upper end of the steel wire rope 8 passes around the pulleys 9 and is fixedly connected to a longitudinal tie rod 10. The tie rod 10 abuts against the outer wall of the lower side of the lifting conveying pipe 2. An inverted L-shaped hook 20 opposite to the tie rod 10 is fixedly connected to the left side wall of the lower part of the column 61. By pulling down the tie rod 10, the material-carrying slide plate 7 can move the bagged flour upward. When the tie rod 10 is engaged in the hook 20, the bagged flour can be cut and processed at the middle of the bottom of the bagged flour, that is, at the feeding opening 712. The flour can then enter the feeding hopper 1 through the feeding opening 712 and the feeding inlet of the pusher frame 5, which can save a lot of effort.

[0027] The distance from the feeding opening 712 on the bearing plate 71 to the feeding inlet on the pusher frame 5 is less than the distance from the pull rod 10 to the hook 20.

[0028] The front and rear side end faces of the bearing plate 71 and the side end faces of the side baffle 72 on the material carrying slide plate 7 are flush with each other. The front and rear side end faces of the bearing plate 71 abut against the inner end face of the side support rod 51, which can limit the shaking of the material carrying slide plate 7.

[0029] Working principle: This structure is a continuous feeding device for pastry premixed powder sieving equipment. The continuous feeding device mainly uses the screw conveyor principle to lift the flour from the feed hopper 1 and then output it from the output bend 4; replacing manual feeding, it can greatly reduce labor intensity.

[0030] However, the feeding hopper 1 of this continuous feeding device still requires manual feeding. Therefore, a pusher frame 5 with a roller sleeve 52 structure is designed. The bagged flour can be pressed against the roller sleeve 52 of the pusher frame 5. Then, one person pulls up the bagged flour and moves it to the feeding inlet, while another person opens the bottom of the flour packaging bag. The flour can then enter the feeding hopper 1. With the support of the pusher frame 5, it can save a lot of effort.

[0031] The embodiments described above are illustrative of the present invention and are not intended to limit the present invention. Any person skilled in the art can modify the embodiments without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be as set forth in the claims.
