Description

Technical fields:

[0001] This utility model relates to the field of food processing equipment technology, and more specifically to a feeding vibrating screen device for premixed powder used in pastries. Background technology:

[0002] Flour is the main ingredient in making pastries. During the pastry-making process, the flour needs to be sieved to improve the quality and smoothness of the finished product, such as through kneading. This sieving is primarily done on a vibrating screen. Specifically, the sieving process involves manually pouring a portion of the flour through the top inlet of the vibrating screen. The flour accumulates in the middle of the top screen mesh. After the screen vibrates for a while, the accumulated flour disperses and is sieved. Then more flour is added. This process cannot achieve continuous feeding, involves multiple pours of flour, and is labor-intensive and inefficient.

[0003] Therefore, the continuous feeding device for the premixed pastry vibrating screen with Chinese patent authorization announcement number CN223056090U, by using a spiral conveying structure to transport the flour in the hopper to the vibrating screen, can save the process of repeated manual feeding. At the same time, it is equipped with a rotating scraper to spread the flour, enabling continuous feeding and improving screening efficiency.

[0004] However, this structure can only meet the conveying needs of a single circular vibrating screen, resulting in low conveying efficiency. Furthermore, it is only suitable for conveying a single type of powder and cannot achieve the mixing and conveying of multiple powders for premixing. In other words, different types of powders cannot be placed in its discharge hopper for premixing, thus limiting its applicability. Utility Model Content:

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a premixed powder feeding vibrating screen device for pastries. It can meet the continuous feeding of two circular vibrating screens and can place various powders on the feeding hopper for premixing, thus meeting the needs of mixing various powders into premixed powder.

[0006] The solution of this utility model to the aforementioned technical problem is:

[0007] A premixed powder feeding vibrating screen device for pastries includes a middle support frame and a feeding hopper, wherein circular vibrating screens are provided on both the left and right sides of the middle support frame.

[0008] A hopper is fixed to the top of the intermediate support frame;

[0009] The hopper is cone-shaped, with its side plates being cone-shaped walls with a larger upper diameter and a smaller lower diameter.

[0015] An arc-shaped cover plate is fixed to the outer wall of the bottom of the stirring blade. The outer wall of the arc-shaped cover plate is closely attached to the inner wall of the side plate of the hopper and corresponds to the corresponding discharge hole.

[0016] The outstanding effect of this utility model is:

[0017] It has two transverse screw conveyors, which can meet the continuous feeding of two circular vibrating screens. At the same time, its discharge hopper is equipped with a stirring device, which can place various powders on the discharge hopper for premixing, meeting the needs of mixing and premixing various powders.

[0021] Figure 3 This is a partial top view of the hopper of this utility model. Detailed implementation method:

[0022] For example, see below. Figures 1 to 3 As shown, a premixed powder feeding vibrating screen device for pastries includes an intermediate support frame 10 and a feeding hopper 40. Elevated seats are fixed on the ground on the left and right sides of the intermediate support frame 10, and a circular vibrating screen 30 (which is a known structure and product and will not be described in detail here) is provided on the top surface of the elevated seats.

[0025] The lower left and right sides of the side plate of the hopper 40 are both formed with material discharge holes 41. The top end of the discharge pipe 42 is connected to the material discharge holes 41, and the bottom end of the discharge pipe 42 is connected to the feed holes of the transverse screw conveyor 50.

[0026] The hopper 40 is equipped with a stirring device, which stirs and mixes the different powders put into the hopper 40.

[0027] Furthermore, the intermediate support frame 10 includes a fixed base plate, a plurality of legs are fixed on the bottom surface of the fixed base plate, the legs are fixed on the ground, and vertical support columns are fixed on the left and right sides of the top surface of the middle part of the fixed base plate, and an intermediate transverse beam is fixed between the middle parts of the two vertical support columns.

[0028] The transverse screw conveyor 50 includes a transverse conveying tube 52. The bottom surface of the transverse conveying tube 52 is fixed to the top surface of the corresponding vertical support column by welding (bolts or other methods can also be used; welding is used in this embodiment). A transverse conveying screw 53 is provided in the transverse conveying tube 52. The two ends of the transverse conveying screw 53 are movably connected to the left and right end plates of the transverse conveying tube 52 by bearings. A conveying motor 54 is fixed on the outer wall of one end plate. The output shaft of the conveying motor 54 is a spline shaft, which is inserted into the spline hole at one end of the corresponding transverse conveying screw 53 and drives the transverse conveying screw 53 to rotate. The outer end of the spiral fins of the transverse conveying screw 53 is close to the inner wall of the transverse conveying tube 52. The top plate of the transverse conveying tube 52 is formed with a feed through hole directly below the discharge through hole 41. The bottom plate of the transverse conveying tube 52 near the outer end is formed with a discharge through hole.

[0029] The top end of the discharge pipe 42 is inserted into the corresponding discharge through hole 41, and its outer side wall is welded and fixed to the inner side wall of the corresponding discharge through hole 41. The bottom end of the discharge pipe 42 is fixedly connected to the top surface of the transverse conveying pipe body 52 by bolts. A sealing ring is clamped between the bottom end of the discharge pipe 42 and the top surface of the transverse conveying pipe body 52. ​​The feed through hole is aligned with and communicates with the middle through hole of the discharge pipe 42.

[0030] The radially extending edge formed on the outer side wall of the top end of the discharge pipe 51 is fixedly connected to the bottom surface of the transverse conveying pipe 52 by bolts (a sealing ring is clamped between the top surface of the radially extending edge and the bottom surface of the transverse conveying pipe 52, and both the bottom and top surfaces of the transverse conveying pipe 52 are flat). The discharge through hole of the transverse screw conveying device 50 is connected to the middle through hole of the discharge pipe 51. The bottom of the discharge pipe 51 is inserted into the upwardly extending sleeve 33 formed on the middle top surface of the top cover 31 and is connected to the middle feed through hole 32 of the sleeve 33.

[0031] Furthermore, an elastic sleeve 1 is fitted onto the discharge pipe 51. The top surface of the elastic sleeve 1 presses against the bottom surface of the radially extending edge of the discharge pipe 51. An annular groove is formed on the inner sidewall of the bottom end of the elastic sleeve 1. The upper part of the sleeve 33 is inserted into the annular groove, the outer sidewall of the upper part of the sleeve 33 presses against the inner sidewall of the annular groove, and the top surface of the sleeve 33 presses against the top surface of the annular groove. The elastic sleeve 1 has a sealing effect.

[0032] Furthermore, a vibrating motor 2 is fixed to the outer wall of the discharge pipe 42. It can be activated 5 to 10 seconds before the conveying motor 54 of the transverse screw conveyor 50 starts running, causing the discharge pipe 42 to vibrate and preventing material blockage. When the conveying motor 54 stops running, the vibrating motor 2 also stops running. The vibrating motor 2 is a small vibrating motor with limited vibration force; its function is only to loosen the powder at the discharge pipe 42 and prevent blockage. Its impact on other mechanical components is negligible and need not be considered.

[0033] Multiple connecting support columns 3 are fixed to the front and rear of the top surface of the fixed base plate, and the lower part of the outer side wall of the hopper 40 is fixed to the top surface of all the connecting support columns 3.

[0034] A horizontal fixing plate 43 is provided in the middle of the top surface of the feeding hopper 40. The front and rear parts of the horizontal fixing plate 43 are fixed to the top surface of the front and rear parts of the side plate of the feeding hopper 40.

[0035] The stirring device includes a stirring motor 44, which is fixed in the middle of the top surface of a horizontal fixed plate 43. The bottom end of the output shaft of the stirring motor 44 extends out of the bottom surface of the horizontal fixed plate 43 and is connected to a stirring shaft 45 through a coupling. A stirring sleeve 46 is fixed on the outer side wall of the stirring shaft 45. Stirring blades 47 are fixed on the left and right sides of the outer side wall of the stirring sleeve 46. The outer side wall of the stirring blades 47 is close to the inner side wall of the side plate of the discharge hopper 40 and cooperates with the inner side wall.

[0036] An arc-shaped cover plate 48 is fixed on the outer side wall of the bottom of the stirring blade 47. The outer side wall of the arc-shaped cover plate 48 is closely attached to the inner side wall of the side plate of the discharge hopper 40 and corresponds to the discharge through hole 41.

[0037] In this embodiment, when in use, the various powders to be transported and mixed are poured into the discharge hopper 40. Then, the stirring motor 44 is run, causing the stirring shaft 45 to rotate, which causes all the stirring blades 47 to rotate, pre-stirring and mixing the various powders in the discharge hopper 40. The arc-shaped cover plate 48 can hang the powder on the lower inner wall of the discharge hopper 40 to prevent the accumulation of powder on the lower inner wall.

[0038] Meanwhile, when the equipment is not in use, the arc-shaped cover plate 48 can cover the corresponding material discharge hole 41. The stirring motor 44 in this embodiment is a common geared motor. Therefore, when the power is off, it can rotate the stirring shaft to cover the corresponding material discharge hole 41 with the arc-shaped cover plate 48.

[0039] When it is necessary to convey the powder to the corresponding circular vibrating screen 30 (the powder in the discharge hopper 40 needs to be pre-mixed by the stirring motor 44 before conveying), the conveying motor 54 of the corresponding transverse screw conveyor 50 can be run. At the same time, its corresponding vibrating motor 2 runs, so that the powder is conveyed into the circular vibrating screen 30. The powder is screened by the vibration of the circular vibrating screen 30. Finally, the powder is output from the discharge end. The receiving cylinder can be placed below the discharge end to receive the powder.

[0040] In this embodiment, two transverse screw conveyors 50 can operate simultaneously to convey materials, or only one transverse screw conveyor 50 can be activated to convey materials on one side, thus meeting different usage requirements.

[0041] The above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, all equivalent technical solutions also fall within the scope of the present utility model. The patent protection scope of the present utility model should be defined by the claims.
