Description

Technical Field

[0001] The embodiments of this disclosure relate to the field of raw material mixing technology, and more specifically, to a feeding mechanism for mixing powdered raw materials. Background Technology

[0002] Feeding equipment for solid or liquid raw materials is already very mature. It includes a shell, as well as feed hoppers and conveying pipes respectively set at the upper and lower parts of the shell. The feeding equipment for liquid raw materials also has a heat exchanger on the outer periphery of the shell to keep the raw material within a specified temperature range.

[0003] According to a public disclosure of a powder material mixing and feeding mechanism (Publication No.: CN212576163U), it includes a mixing chamber, a feed pipe, a discharge pipe, a motor, a motor mounting base, a stirring shaft, an eccentric wheel, and an elastic support base. Multiple feed pipes are connected to the top of the mixing chamber, and the discharge pipes are connected to the bottom of the mixing chamber. Each feed pipe has a first corrugated section, and each discharge pipe has a second corrugated section. The elastic support base is located at the bottom of the mixing chamber, and the motor mounting base is located at the bottom of the motor. The mixing chamber has an elastic sealing membrane on its side wall, and a bearing is mounted on the elastic sealing membrane. The eccentric wheel is located inside the mixing chamber. During rotation, the long axis of the eccentric wheel abuts against the bottom surface of the mixing chamber, while the short axis does not abut against the bottom surface. However, the device, with the cooperation of components such as the stirring shaft, eccentric wheel, and elastic support, makes it difficult to control the opening and closing of the feed port, ensure precise control of the feeding process, and avoid overfeeding or underfeeding due to other factors. Improvements are needed. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide a feeding mechanism for mixing powdered raw materials, which solves the technical problems in the prior art that make it difficult to control the opening and closing of the feed port, difficult to ensure precise control of the feeding process, and difficult to avoid excessive or insufficient feeding caused by other factors.

[0005] According to one aspect, at least one embodiment of this disclosure provides a feeding mechanism for mixing powdered raw materials, including a support frame, a fixing plate fixedly connected to the side of the support frame, a feeding box fixedly connected to the top of the fixing plate, and a discharge pipe penetrating the bottom of the feeding box;

[0006] A feeding device is provided on the top of the fixed plate. The feeding device includes a support rod, which is fixedly connected to the top of the feeding box. A protective sleeve is fixedly connected to the top of the support rod. A reciprocating screw passes through the top of the protective sleeve. A threaded block is threaded to the circumferential surface of the reciprocating screw. A fixing rod is fixedly connected to the side of the threaded block. A positioning plate is fixedly connected to the end of the fixing rod away from the threaded block. A rotating rod is fixedly connected to the top of the reciprocating screw.

[0007] For example, in a feeding mechanism for mixing powdered raw materials provided in at least one embodiment of this disclosure, a limiting rod is further provided through the top of the threaded block. One end of the limiting rod is fixedly connected to the bottom of the support rod. By limiting the threaded block with the limiting rod at the top, it can be ensured that each displacement can accurately reach the predetermined position, avoiding excessive or insufficient displacement, and helping to control the precise amount of powdered raw materials fed.

[0008] The fixed rod is L-shaped and several in number, arranged in a circumferential array on the side of the threaded block. The design of the fixed rod can control the position of the positioning plate, thereby controlling the opening and closing of the feed port.

[0009] According to another aspect, at least one embodiment of this disclosure also provides a feeding mechanism for mixing powdered raw materials, including a feeding device comprising a quantitative feeding structure, the quantitative feeding structure comprising a rectangular plate, the rectangular plate being fixedly connected to the side of a support frame, a motor being fixedly connected to the bottom of the rectangular plate, a rotating rod being fixedly connected to the output shaft of the motor, a half gear being fixedly connected to the circumferential surface of the rotating rod, a fixed frame being fixedly connected to the side of the support frame, a sliding plate being slidably connected to the side of the fixed frame, a connecting pipe penetrating the top of the sliding plate, a protective shell penetrating the top of the connecting pipe, a rotating shaft being rotatably connected to the circumferential surface of the connecting pipe, a feeding plate being fixedly connected to the circumferential surface of the rotating shaft, an mounting plate being fixedly connected to the side of the support frame, a positioning rod being fixedly connected to the side of the sliding plate, and a rack being fixedly connected to the end of the positioning rod away from the sliding plate.

[0010] For example, in a feeding mechanism for mixing powdered raw materials provided in at least one embodiment of this disclosure, a support plate is fixedly connected to the side of the fixed frame, and a spring is fixedly connected to the side of the support plate. The end of the spring away from the support plate is fixedly connected to the side of the rack. The design of the spring can enable the rack to automatically reset, reducing manual intervention.

[0011] The spring is initially in a relaxed state. The rack and the half gear mesh with each other on the toothed side. The design of the rack and the half gear causes the connecting tube to reciprocate.

[0012] A torsion spring is fixedly connected to the circumferential surface of the connecting tube. The end of the torsion spring away from the connecting tube is fixedly connected to the circumferential surface of the rotating shaft. The design of the torsion spring enables the feeding plate to automatically reset, thereby achieving the function of quantitative feeding.

[0013] The torsion spring is initially in a taut state. The inner wall of the protective sleeve is threaded to the circumferential surface of the reciprocating lead screw. The design of the torsion spring enables the feed plate to automatically reset, reducing manual intervention.

[0014] The number of limiting rods is set to several, and they are arranged in a circumferential array on the top of the threaded block. The design of the limiting rods effectively limits the threaded block and increases the stability of the device.

[0015] The mounting plate is located at the bottom of the feeding plate, and the side of the positioning rod is slidably connected to the side of the fixing frame. The design of the mounting plate can limit the feeding plate and accurately control the opening and closing of the feeding port to ensure that the feeding amount reaches the predetermined value each time.

[0016] The beneficial effects of the embodiments disclosed herein are as follows:

[0017] 1. In this disclosure, the force of rotating the rotating rod to drive the reciprocating screw to rotate, in conjunction with the limiting rod, fixing rod, and positioning plate in the feeding device, achieves the effect of limiting the threaded block by the limiting rod at the top of the threaded block, then driving the fixing rod to move by the displacement of the threaded block, and driving the positioning plate to move by the displacement of the fixing rod, thereby opening the discharge port at the bottom of the feeding box. This achieves the effect of controlling the opening and closing of the discharge port, ensuring precise control of the feeding process, and avoiding overfeeding or underfeeding caused by other factors.

[0018] 2. In this disclosure, the force of the rotating rod driven by the motor cooperates with the positioning rod, support plate, and mounting plate in the feeding device. This achieves the following: when the toothed side of the half gear moves away from the rack, the rack drives the positioning rod to reset through the spring force, thereby resetting the connecting pipe and protective shell. The feeding plate is also reset by the squeezing action of the mounting plate, achieving the effect of quantitative feeding. This allows for precise control of the opening and closing of the feeding port, ensuring that the feeding amount reaches the predetermined value each time and avoiding overfeeding or underfeeding.

Detailed Implementation

[0026] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0027] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0028] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0029] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0030] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0031] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] like Figures 1-5 As shown, it illustrates a powdered raw material mixing feeding mechanism in one embodiment of the present disclosure, including a support frame 101, a fixing plate 102 fixedly connected to the side of the support frame 101, a feeding box 103 fixedly connected to the top of the fixing plate 102, and a discharge pipe 104 penetrating the bottom of the feeding box 103.

[0033] A feeding device 2 is provided on the top of the fixed plate 102. The feeding device 2 includes a support rod 201, which is fixedly connected to the top of the feeding box 103. A protective sleeve 202 is fixedly connected to the top of the support rod 201. A reciprocating screw 203 passes through the top of the protective sleeve 202. A threaded block 205 is threadedly connected to the circumferential surface of the reciprocating screw 203. A fixing rod 207 is fixedly connected to the side of the threaded block 205. A positioning plate 208 is fixedly connected to the end of the fixing rod 207 away from the threaded block 205. A rotating rod 204 is fixedly connected to the top of the reciprocating screw 203.

[0034] In some examples, the top of the threaded block 205 passes through a limiting rod 206, one end of which is fixedly connected to the bottom of the support rod 201. By limiting the threaded block 205 with the limiting rod 206 at the top, it can be ensured that each displacement can accurately reach the predetermined position, avoiding excessive or insufficient displacement, and helping to control the precise amount of powdered raw materials.

[0035] The fixed rod 207 is L-shaped, and the number of fixed rods 207 is set to several. They are arranged in a circumferential array on the side of the threaded block 205. The design of the fixed rod 207 can control the position of the positioning plate 208, thereby controlling the opening and closing of the feed port.

[0036] For example, such as Figures 1-5 As shown, this application rotates the rotating rod 204 to drive the reciprocating screw 203 to rotate, and then the rotation of the reciprocating screw 203 drives the threaded block 205 to move. The threaded block 205 is limited by the limiting rod 206 at the top of the threaded block 205. Then, the displacement of the threaded block 205 drives the fixed rod 207 to move, and the displacement of the fixed rod 207 drives the positioning plate 208 to move, so that the discharge port at the bottom of the feed box 103 opens, thus realizing the function of discharging materials.

[0037] like Figures 1-5 As shown, this illustrates a feeding mechanism for mixing powdered raw materials according to another embodiment of the present disclosure. The feeding device 2 includes a quantitative feeding structure, which comprises a rectangular plate 209 fixedly connected to the side of a support frame 101. A motor 210 is fixedly connected to the bottom of the rectangular plate 209. A rotating rod 211 is fixedly connected to the output shaft of the motor 210. A half-gear 212 is fixedly connected to the circumferential surface of the rotating rod 211. A fixing frame 213 is fixedly connected to the side of the support frame 101. A sliding plate 224 is slidably connected to the side of the fixed frame 213. A connecting pipe 215 passes through the top of the sliding plate 224. A protective shell 214 passes through the top of the connecting pipe 215. A rotating shaft 216 is rotatably connected to the circumferential surface of the connecting pipe 215. A feeding plate 218 is fixedly connected to the circumferential surface of the rotating shaft 216. An mounting plate 219 is fixedly connected to the side of the support frame 101. A positioning rod 222 is fixedly connected to the side of the sliding plate 224. A rack 223 is fixedly connected to the end of the positioning rod 222 away from the sliding plate 224.

[0038] In some examples, a support plate 220 is fixedly connected to the side of the bracket 213, and a spring 221 is fixedly connected to the side of the support plate 220. The end of the spring 221 away from the support plate 220 is fixedly connected to the side of the rack 223. The design of the spring 221 can make the rack 223 automatically reset, reducing manual intervention.

[0039] The spring 221 is initially in a relaxed state. The rack 223 and the toothed side of the half gear 212 mesh with each other. The design of the rack 223 and the half gear 212 causes the connecting tube 215 to reciprocate.

[0040] A torsion spring 217 is fixedly connected to the circumferential surface of the connecting tube 215. The end of the torsion spring 217 away from the connecting tube 215 is fixedly connected to the circumferential surface of the rotating shaft 216. The design of the torsion spring 217 enables the feeding plate 218 to automatically reset, thereby achieving the function of quantitative feeding.

[0041] The torsion spring 217 is initially in a taut state. The inner wall of the protective sleeve 202 is threadedly connected to the circumferential surface of the reciprocating screw 203. The design of the torsion spring 217 enables the feed plate 218 to automatically reset, reducing manual intervention.

[0042] The number of limiting rods 206 is set to several, and they are arranged in a circumferential array on the top of the threaded block 205. The design of the limiting rods 206 effectively limits the threaded block 205 and increases the stability of the device.

[0043] The mounting plate 219 is located at the bottom of the feeding plate 218. The side of the positioning rod 222 is slidably connected to the side of the fixing frame 213. The design of the mounting plate 219 can limit the feeding plate 218, accurately control the opening and closing of the feeding port, and ensure that the feeding amount reaches the predetermined value each time.

[0044] For example, such as Figures 1-5 As shown, the motor 210 drives the rotating rod 211 to rotate, which in turn drives the half gear 212 to rotate. When the toothed side of the half gear 212 meshes with the rack 223, the rotation of the half gear 212 causes the rack 223 to move, which in turn causes the positioning rod 222 to move, which in turn causes the sliding plate 224 to move, which in turn causes the connecting pipe 215 to move, which in turn causes the protective shell 214 to move, and so on. The rotating shaft 216 is displaced, which in turn causes the feeding plate 218 to move. When the feeding plate 218 moves away from the mounting plate 219, it loses its limit and rotates downwards due to the elastic force of the torsion spring 217, opening the feeding port at the bottom of the connecting pipe 215. When the toothed side of the half gear 212 moves away from the rack 223, the rack 223 drives the positioning rod 222 to reset due to the elastic force of the spring 221, thereby resetting the connecting pipe 215 and the protective shell 214. The feeding plate 218 is then reset by the pressure of the mounting plate 219, thus achieving the function of quantitative feeding.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
