[0036] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Please see Figures 1-9 This utility model provides a technical solution for a feeding device.

[0038] A feeding device 101 includes:

[0039] Base plate 1;

[0040] The material feeding bracket 102 is fixed on the base plate 1;

[0041] The feeding assembly is mounted on the feeding bracket 102. The feeding assembly includes a feeding barrel 103, a storage cavity 104 inside the feeding barrel 103, a feeding head 105 installed at the lower end of the feeding barrel 103, a feeding groove 106 inside the feeding head 105, the feeding groove 106 including a feeding inlet 107 and a feeding outlet 108, the feeding inlet 107 and the storage cavity 104 are connected, a feeding disc 109 is rotatably connected inside the feeding groove 106, a plurality of feeding protrusions 110 evenly distributed around the circumference of the feeding disc are provided on the outer wall of the feeding disc 109, an arc groove 111 is provided on the inner wall of the feeding groove 106, some of the feeding protrusions 110 abut against the inner wall of the arc groove 111, and the feeding protrusions 110 separate the feeding inlet 107 and the feeding outlet 108.

[0042] The feeding drive device is used to drive the feeding disc 109 to rotate.

[0043] The raw material to be fed (such as anhydrous magnesium sulfate or sodium chloride) is placed into the storage chamber 104 of the feeding barrel 103. At this time, some raw material will be located between the upper feeding protrusions 110. The test tube containing the raw material is placed below the feeding outlet 108. Then, the feeding drive device drives the feeding disc 109 to rotate, and the feeding protrusions 110 can carry the raw material to the feeding outlet 108. The raw material falls from the feeding outlet 108 into the test tube. The weight of the raw material output after one rotation of the feeding disc 109 is detected in advance, so that the number of rotations can be adjusted according to the weight of the raw material. One feeding device corresponds to one type of raw material, thus enabling the rapid output of various raw materials.

[0044] like Figure 7 As shown, the feeding protrusion 110 is set as a brush, which can convey raw materials with relatively high precision.

[0045] like Figures 4-9 As shown, the feeding tray 109 is rotatably connected to the feeding groove 106 via the feeding shaft 112. The feeding shaft 112 extends out of the feeding head 105 and is fixed with a feeding driven gear 113. The feeding drive device includes a feeding drive motor 114 and a feeding drive gear 115. The feeding drive motor 114 is fixed on the feeding bracket 102, and the feeding drive gear 115 is fixed on the shaft of the feeding drive motor 114. The feeding drive gear 115 meshes with the feeding driven gear 113.

[0046] The feeding drive motor 114 drives the feeding drive gear 115 to rotate, and the feeding drive gear 115 drives the feeding driven gear 113 to rotate, thereby driving the feeding disc 109 to rotate to realize feeding.

[0047] In order to stir the raw materials in the feeding barrel 103, such as Figures 4-9As shown, a stirring base plate 116 is fixed to the upper end of the feeding barrel 103. A stirring shaft 117 is rotatably connected to the stirring base plate 116. A stirring component is installed on the part of the stirring shaft 117 located in the storage cavity 104. A stirring driven gear 118 is fixed to one end of the stirring shaft 117 that extends out of the stirring base plate 116. A stirring drive motor 119 is fixed to the feeding bracket 102. A stirring drive gear 120 is fixed to the shaft of the stirring drive motor 119. The stirring drive gear 120 meshes with the stirring driven gear 118.

[0048] The stirring drive motor 119 drives the stirring drive gear 120 to rotate, the stirring drive gear 120 drives the stirring driven gear 118 to rotate, thereby driving the stirring shaft 117 to rotate, the stirring shaft 117 drives the stirring component to rotate, and the stirring component can play the role of stirring the raw materials in the feeding barrel 103.

[0049] like Figures 4-9 As shown, two feeding supports 121 are fixed at the lower end of the feeding barrel 103. Each feeding support 121 is fixed with a feeding limit pin 122. The feeding head 105 is provided with a feeding limit groove 123 for the feeding limit pin 122 to be inserted.

[0050] When the feeding limit pin 122 is inserted into the feeding limit groove 123, the feeding head 105 can be connected to the feeding barrel 103. When it is necessary to remove the feeding head 105, simply move the feeding limit pin 122 out of the feeding limit groove 123.

[0051] The unloading limit pin 122 is set as an indexing pin, which is an existing component. The indexing pin is fixed on the unloading support 121. The inner end of the indexing pin can be moved out of the unloading limit groove 123 simply by pulling the outer end of the indexing pin outward. When the outer end of the indexing pin is released, its inner end will return to its original position and insert into the unloading limit groove 123.

[0052] like Figures 4-9 As shown, the feeding bracket 102 is provided with a feeding bracket plate 124, the feeding bracket plate 124 is provided with a feeding groove 125, and two feeding fixing blocks 126 are fixed on the feeding bracket plate 124. The two feeding fixing blocks 126 are located on both sides of the feeding groove 125. The feeding fixing blocks 126 are provided with feeding slots 127, and the stirring plate 116 is fixed with a plugging protrusion 128 that plugs into the feeding slot 127.

[0053] Using the above method, when the insertion protrusion 128 is inserted into the feeding slot 127, the upper end of the feeding barrel 103 is inserted into the feeding groove 125. The stirring drive gear 120 meshes with the stirring driven gear 118, and the feeding drive gear 115 meshes with the feeding driven gear 113. This indicates that feeding and stirring actions can be performed. When it is necessary to add raw materials to the storage cavity 104, the insertion protrusion 128 can be moved out of the feeding slot 127. At this time, the stirring drive gear 120 and the stirring driven gear 118 separate, and the feeding drive gear 115 and the feeding driven gear 113 also separate. Then, the entire feeding barrel 103 can be removed. Then, the feeding limit pin 122 is moved out of the feeding limit groove 123, and the feeding head 105 can be disassembled. Then, raw materials can be put into the feeding barrel 103. After putting them in, the feeding head 105 can be installed.

[0054] Using the above method, the feeding barrel 103 can also be replaced with different raw materials. A feeding bracket 102, a feeding drive device, a stirring drive motor 119 and a stirring drive gear 120 can be adapted to the feeding barrel 103 of different raw materials.

[0055] like Figure 4 As shown, the feeding device 101 also includes a pressing and rotating device. A feeding pressing rod 130 is rotatably connected to the feeding bracket 102. The feeding pressing rod 130 has a pressing state and an unlocking state. In the pressing state, the feeding pressing rod 130 is located on the side of the feeding barrel 103 away from the feeding groove 125. In the unlocking state, the feeding pressing rod 130 rotates away from the feeding barrel 103, and the pressing and rotating device drives the feeding pressing rod 130 to rotate.

[0056] like Figure 4 As shown, the insertion protrusion 128 is inserted into the feeding slot 127 to install the feeding barrel 103 into place. The clamping rotation device drives the feeding clamping rod 130 to rotate, causing the feeding clamping rod 130 to abut against the side of the feeding barrel 103 opposite to the feeding groove 125, thus restricting the position of the feeding barrel 103 and preventing it from moving. When it is necessary to remove the feeding barrel 103, the feeding clamping rod 130 rotates away from the feeding barrel 103, allowing the feeding barrel 103 to be removed.

[0057] like Figure 4 As shown, the clamping and rotating device is configured as a clamping cylinder 131. The housing of the clamping cylinder 131 is rotatably connected to the unloading bracket 102, and the piston rod of the clamping cylinder 131 is rotatably connected to the unloading clamping rod 130. The extension and retraction of the piston rod of the clamping cylinder 131 can drive the unloading clamping rod 130 to rotate.

[0058] like Figures 4-9As shown, the upper end of the discharge head 105 is provided with a conical groove 132. The stirring component includes a U-shaped rod 133 and a conical rod. The two ends of the U-shaped rod 133 are fixedly connected to the stirring shaft 117. The U-shaped rod 133 is located inside the storage cavity 104. The conical rod includes a conical crossbar 134 and a conical inclined rod 129. The conical crossbar 134 is fixedly connected to the stirring shaft 117. The conical inclined rod 129 is located inside the conical groove 132, and the inclination angle of the conical inclined rod 129 is the same as that of the conical groove 132. When the stirring shaft 117 rotates, the U-shaped rod 133 and the conical rod can stir the raw materials in the storage cavity 104 and the conical groove 132.

[0059] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
