Description

Technical Field

[0001] The utility model relates to the field of food production, in particular to an auxiliary feeding device. Background Art

[0002] In the dry mixing production process of powdered food, a three-dimensional mixer is often used. The raw materials are fed into the three-dimensional mixer through the feeding port, and the feeding port is closed to enter the mixing process.

[0003] Usually, the powder particles of dry mixed products are small. During the feeding process, a lot of dust will be generated, which will affect the working environment of the workshop. After the scattered powder materials fall on the ground, it is not easy to clean up. If the humidity in the workshop is high, it will also cause the microorganisms in the clean workshop to exceed the standard.

[0004] The prior art process of feeding powder raw materials is as follows: for small batches of products, the weight of the materials is checked one by one using an electronic platform scale, and for the checked materials, the materials are slowly loaded into the three-dimensional mixer using a long-handled ladle. The disadvantage of this prior art is that this process consumes a lot of manpower, inevitably causes the powder to float or spill, and increases the probability of personnel contaminating the materials.

[0005] For products with large batches, the main material is fed through a vacuum feeder. The loss of trace materials (vitamins, minerals, etc.) during the feeding process is large and difficult to control. Therefore, trace materials (vitamins, minerals, etc.) are generally fed manually. According to the mixing process, vitamins and minerals are generally in the middle of the feeding sequence, which causes the feeding process to be divided into three steps. The first step is to feed part of the material through a vacuum feeder; the second step is to disassemble the vacuum feeder and then manually add trace materials (vitamins, minerals, etc.); the third step is to reinstall the vacuum feeder and feed other materials. It can be seen that this process takes a long time and is complicated to operate. The powder adsorbed in the pipeline and dust recovery barrel cannot be recycled, which increases the material loss rate. Utility Model Content

[0006] The utility model aims to provide an auxiliary feeding device to solve the technical problem of the inconvenience of the powder raw material feeding process in the prior art.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] An auxiliary feeding device comprises a conveying device, a material bucket and a funnel, wherein the conveying device comprises a frame, the frame comprises a vertical section and a horizontal section, the upper end of the vertical section forms an upper supporting surface,

[0009] The horizontal section is provided with a lifting platform 1 and a lifting platform 2 along its extension direction, and a lifting column for controlling the lifting platform 1 and the lifting platform 2 to independently lift is also provided on the horizontal section.

[0010] The vertical section is provided with a conveying part which can move in the up-down direction, the conveying part is provided with an interface, and the interface is provided with a fixing rod which can rotate around the axis direction of the interface.

[0011] A fixing interface is provided on one side of the barrel, and the fixing interface matches the fixing rod so that the fixing rod can be inserted therein, and the fixing interface is located at the lower part of the barrel body.

[0012] The funnel includes a funnel body and a connecting structure. The lower end of the funnel body is used to extend into the feed port of the three-dimensional mixer. The connecting structure is used to be fixed on the three-dimensional mixer. The upper contour of the upper end opening of the funnel body is higher than the upper supporting surface, and the lower contour is lower than the upper supporting surface.

[0013] Further, a lower contour line of the opening of the funnel body is in a straight line shape so as to abut against a side surface of the vertical section facing away from the horizontal section.

[0014] Furthermore, the opening of the funnel body is a special-shaped opening, and the upper contour of the opening is an arc shape.

[0015] Furthermore, the inner wall surface of the funnel body is a mirror surface.

[0016] Furthermore, the connection structure is a flange connection structure.

[0017] Furthermore, the conveying part is a conveyor belt, and a yield groove is provided on the vertical section.

[0018] Furthermore, the cross-section of the vertical section is in a convex shape, and the clearance grooves are provided on both sides of the small cross-section portion of the vertical section.

[0019] Furthermore, handles are provided on both sides of the barrel.

[0020] Furthermore, a universal wheel is arranged at the bottom of the frame, and a push rod is arranged on the vertical section of the frame, and the push rod is located on the side of the vertical section away from the horizontal section.

[0021] Compared with the prior art, the utility model has the following beneficial effects:

[0022] When using the utility model to load materials, in the first stage, the conveying part, lifting platform 1, and lifting platform 2 work together to drive the material barrel to lift. In the second stage, from the time the fixed interface on the material barrel is lifted to slightly below the upper support surface, only lifting platform 2 moves upward, pushing the barrel mouth of the material barrel to tilt toward the side where the funnel is located. In the third stage, from the time the material barrel contacts the upper support surface, the conveying part, lifting platform 1, and lifting platform 2 work together to further lift the material barrel. During this process, the tilt amplitude of the material barrel will further increase. When the material barrel is parallel to the upper support surface, lifting platform 2 stops running. In the fourth stage, from the time the fixed rod on the conveying part runs to the highest point, only lifting platform 1 moves upward, pushing the barrel mouth of the material barrel to tilt downward and guiding the material in the barrel into the three-dimensional mixer through the funnel.

[0023] The utility model decomposes the feeding action into four stages through the cooperation of the lifting platform 1, the lifting platform 2 and the conveying part. The action amplitude of each stage is small, which not only realizes automatic feeding, but also reduces the powder dispersion. When loading different materials, it is only necessary to place different material barrels at the appropriate position of the frame, which is convenient to operate.

[0024] The parts not involved in the device are the same as the existing technology or can be implemented by using the existing technology. The utility model has a scientific and reasonable structure, is safe and convenient to use, and provides great help to people. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] An embodiment of an auxiliary feeding device of the utility model:

[0037] An auxiliary loading device includes a conveyor 100, a bucket 200 and a hopper 300. The conveyor 100 includes an L-shaped frame 11, a segmented lifting platform is arranged on the horizontal section of the frame 11, and a conveyor belt 15 and a fixing rod 16 are arranged on the vertical section of the frame 11. The segmented lifting platform includes a lifting platform 12 and a lifting platform 2 13, and the lifting platform 12 and the lifting platform 2 13 are arranged at intervals along the extension direction of the horizontal section of the frame 11, and the two lifting platforms are supported by four adjustable lifting columns 14. The conveyor belt 15 is an annular device, and has an interface on the side facing the horizontal section of the frame 11, and the fixing rod 16 is installed on the conveyor belt 15 through the interface. A hand push rod 17 is arranged on the side of the vertical section of the frame 11 away from the horizontal section, and wheels are arranged at the bottom of the frame 11. The upper end of the vertical section of the frame 11 is an upper support surface 18, and the edge of the upper support surface 18 is rounded to avoid scratching the bucket 200. In other embodiments, a food-contact silicone material may also be provided on the upper support surface 18 to protect the material barrel 200 .

[0038] The material barrel 200 includes a barrel body 21 and handles 22 located on both sides of the barrel body. A fixing interface 23 is provided on one side of the barrel body 21. The fixing interface 23 is hollow inside and is used to insert the fixing rod 16. The size of the bottom of the barrel body 21 (hereinafter referred to as the barrel bottom) is adapted to the total bearing area of ​​the lifting platform 12 and the lifting platform 2 13. Therefore, when the barrel body 21 is placed on the lifting platform, its barrel bottom will span the lifting platform 12 and the lifting platform 2 13.

[0039] It should be emphasized here that the fixing rod 16 is rotatably connected to the conveyor belt 15, and the rotation axis is along the width direction of the conveyor belt 15 to facilitate the fixing rod 16 to be inserted into the fixing interface 23. Specifically, a connecting arm is inserted into the interface of the conveyor belt 15, and the fixing rod 16 is installed on the connecting arm. The fixing rod 16 can rotate relative to the conveyor belt 15 by the connecting arm being rotatable relative to the interface or the fixing rod 16 being rotatable relative to the connecting arm.

[0040] The funnel 300 includes a funnel body 31 and a flange connection structure 32. The lower end of the funnel body 31 can penetrate into the interior of the three-dimensional mixer 400. The flange connection structure 32 is adapted to the feed port of the three-dimensional mixer 400. The funnel body 31 can be fixed by the flange connection structure 32 and the lower end of the funnel body 31 can be extended into the feed port of the three-dimensional mixer 400. The upper end opening of the funnel body 31 is a special-shaped structure, the upper end of the opening is high and the lower end is low, the contour line of the upper end is arc-shaped, and the lower end is straight. The opening of the funnel body 31 is against the side of the vertical section of the frame 11 away from the horizontal section through the lower end, so the upper support surface 18 of the frame 11 will be higher than the straight contour of the lower end of the opening of the funnel body 31. The inner wall surface of the funnel body 31 is a mirror surface to ensure that the powder material will not adhere to the inner wall surface of the funnel body 31.

[0041] The principle of feeding materials using the present invention is as follows: fix the funnel 300 through the flange fixing structure 32 so that the lower end of the funnel body 31 extends into the feed port of the three-dimensional mixer 400. Pull the frame 11 through the push rod 17 so that the lower straight section of the special-shaped opening of the funnel body 31 is against the side of the frame 11. Lock the wheels 19 at the bottom of the frame 11. Place the weighed material in the barrel 200, move the barrel 200 to the segmented lifting platform through the handle 22, and make the fixed interface 23 on the barrel body 21 face the conveyor belt 15. At this time, the position of the barrel 200 is as shown in the figure 21 (a). Turn the conveyor belt 15 to adjust the position of the interface, and make the fixing rod 16 snap into the fixing interface 23.

[0042] In the first stage of the loading process, the conveyor belt 15 and the lifting column 14 are started, so that the 8 groups of lifting columns 14 and the conveyor belt 15 are synchronously conveyed upward to ensure that the position between the fixed interface 23 and the fixed rod 16 remains relatively unchanged. When the fixed interface 23 rises to the set height (slightly lower than the upper support surface 18), the conveyor belt 15 and the lifting column 14 under the lifting platform 1 12 are closed, and the second stage is entered. In the second stage, the lifting platform 2 13 continues to move upward, and the lifting platform 2 13 gradually tilts the mouth of the barrel 200 toward the funnel 200 until it contacts the right side of the upper support surface 18 (specifically, the position shown in 21 (b) in the figure). Then, the third stage is entered, and the lifting platform 1 12 and the conveyor belt 15 are started to continue to move upward, so that the bottom of the barrel 200 moves upward with the contact point as the center of the circle. When the lifting platform 2 13 rises to be flush with the upper support surface 18 (specifically, the position shown in 21 (c) in the figure), the lifting platform 2 13 stops running, and then the fourth stage is entered. In the fourth stage, the lifting platform 12 and the conveyor belt 15 continue to move upward. At this time, the barrel 200 is no longer in contact with the side of the frame 11 close to the horizontal plane (i.e., the close side) but turns to contact with the side of the frame 11 away from the horizontal plane (i.e., the away side). The support of the frame 11 to the barrel 200 is changed from the close side to the away side. When the interface on the conveyor belt 15 runs to the top, the conveyor belt 15 and the lifting platform 12 stop running at the same time. At this time, the fixed interface 23 on the barrel 200 is located above the interface on the conveyor belt 15. At this time, the opening of the barrel 200 is tilted downward (specifically, the position indicated by 21 (d) in the figure), and the material at the bottom of the barrel can flow out of the barrel 200 smoothly and enter the three-dimensional mixer through the funnel 300.

[0043] It should be emphasized that the fixed interface 23 needs to be located at the lower part of the barrel body 21 to ensure that the barrel can be rotated downward according to the set process to a tilting range that allows the material to be poured out in the third and fourth stages.

[0044] When all the materials have flowed out, the lifting platform 12 and the conveyor belt 15 are started to move downward, driving the barrel 200 to return to the original path. When the barrel 200 contacts the lifting platform 2 13, the lifting platform 2 13 is started, and the two lifting platforms keep moving downward at the same speed until they reach the bottom. The fixing rod 16 is pulled out from the fixing interface 23, and the next barrel 200 is replaced to enter the next feeding process. When all the powder materials are loaded, the funnel 300 is removed, and the feeding port cover of the three-dimensional mixer 400 is covered to enter the mixing process.

[0045] The motion control of the lifting platform 12, the lifting platform 13 and the conveyor belt 15 is realized through the control panel 10. In other embodiments, the conveyor belt 15 can also be replaced by a conveying part with a linear displacement output end such as a linear push rod and a linear cylinder.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
