Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0035] The feeding assembly of the first aspect embodiment of the present utility model is described below with reference to the accompanying drawings of the specification. It should be noted that, for the convenience of description and understanding, in the embodiments of the present utility model, the left-right direction is taken as the first direction, the up-down direction is taken as the second direction, and the front-rear direction is taken as the third direction. The first direction, the second direction and the third direction intersect with each other.

[0036] The present utility model embodiment provides a kind of feeding assembly 100 for mixed material, refer to Figures 1 to 3 、And Figure 6 As shown, feeding assembly 100 includes feeding pipe 110, feeding bin 120, plugboard 130 and cover body 140, wherein, the inside of feeding pipe 110 defines feeding passage 111, feeding passage 111 is used to conduct material, so that material enters bin body 200 to be mixed. Bin body 200 is the component of mixed material. The inside of feeding bin 120 defines movable cavity 121, movable cavity 121 is communicated with feeding bin 120 to form feeding port 122 and through hole 123, in the embodiment, movable cavity 121 is communicated with feeding bin 120 to form feeding port 122 along the second direction, and is communicated with feeding bin 120 to form through hole 123 along the third direction. Feeding port 122 and through hole 123 are arranged separately, since feeding port 122 is used to communicate material, through hole 123 is used to communicate airflow to balance air pressure difference. Since material needs to be closed by plugboard 130 to avoid material from pouring back from feeding port 122 when material is mixed, therefore, the separate arrangement of feeding port 122 and through hole 123 can avoid the pouring back of material, and also can improve the air permeability of feeding assembly 100 to balance air pressure difference. Feeding pipe 110 is connected to feeding bin 120 and communicates with feeding port 122, so that material can enter bin body 200 to be mixed after entering feeding passage 111. The inside of cover body 140 defines accommodating cavity 141, cover body 140 is covered in through hole 123, and accommodating cavity 141 communicates with movable cavity 121.

[0037] The plug plate 130 is arranged in the movable cavity 121, wherein the plug plate 130 is movable relative to the material bin 120 along the first direction and has a first position and a second position. In this embodiment, the plug plate 130 is switched between the first position and the second position by driving of a pneumatic cylinder. In other embodiments, the plug plate 130 can also be movable relative to the material bin 120 by gear transmission, belt transmission, chain transmission, etc. In the first position, the plug plate 130 is arranged in the material inlet 122 to close the material inlet 122. Since the materials need to be mixed in a certain proportion, closing the material inlet 122 by the plug plate 130 can avoid impurities from entering the bin body 200 from the material inlet 122, affecting the mixing quality of the materials, and at the same time, the plug plate 130 can also avoid the materials from splashing out of the material feeding assembly 100. In the second position, the plug plate 130 is arranged in the second position to exit the material inlet 122, and at this time, the material feeding channel 111 is communicated with the material inlet 122, and the plug plate 130 avoids the materials. Since the materials in the material feeding channel 111 pass through the material inlet 122 by gravity, the plug plate 130 exits the material inlet 122 to avoid the impact of the materials on the plug plate 130 when the materials pass through the material inlet 122, causing deformation of the plug plate 130.

[0038] Specifically, referring to Figures 1 to 6 Since the plug plate 130 needs to be movable relative to the material bin 120 along the first direction, the edge of the plug plate 130 needs to have a gap with the inner wall of the material bin 120 to ensure the movement of the plug plate 130. When the materials are mixed, the materials will splash and the air pressure in the mixing cavity 210 will change, thereby causing part of the materials to adhere to the plug plate 130. The mixing cavity 210 is a cavity in which the materials are accommodated in the bin body 200. When the plug plate 130 is switched from the first position to the second position, the materials will overflow the material feeding assembly 100 under the action of the air pressure, and therefore the through hole 123 needs to be arranged to alleviate the air pressure difference and reduce the overflow of the materials. The cover body 140 is provided with a breathable hole to promote the flow of air in the movable cavity 121, and since the materials adhered to the plug plate 130 will be extruded by the plug plate 130 during the movement of the plug plate 130, by arranging the cover body 140 and covering the cover body 140 at the through hole 123, the splashing of the materials and the falling of the materials from the through hole 123 can be avoided, thereby reducing the pollution of the materials to the environment.

[0039] The utility model discloses an embodiment of material feeding assembly 100 through the movement of the plug -in board 130 relative to the material bin 120 to switch in the first position and the second position, wherein, the plug -in board 130 is closed in the first position material inlet 122, to avoid material splashing during mixing, the plug -in board 130 second position exits material inlet 122, avoid the material of material feeding to the impact of plug -in board 130 causes the deformation of plug -in board 130. And, on the material bin 120 is provided with through -hole 123, to improve the air permeability of material feeding assembly 100, reduce the air pressure difference in the material mixing process, thereby reducing the splashing of material. Cover body 140 covers in through -hole 123, can accommodate collection when material splashing, avoid the pollution of material to the environment.

[0040] In some embodiments, referring to Figures 1 to 5 As shown, material feeding assembly 100 still includes support 150, and support 150 is connected to the outer wall of material bin 120 and is arranged around through -hole 123. When cover body 140 is covered on through -hole 123 by connecting support 150, support 150 is arranged in accommodating cavity 141 of cover body 140. Specifically, support 150 is arranged along the third direction. Support 150 is connected to the inner wall of cover body 140 to support cover body 140. When cover body 140 needs to be covered on through -hole 123, since support 150 is arranged around through -hole 123, cover body 140 can be sleeved on support 150 to realize the covering of through -hole 123, thereby collecting the material overflowing from through -hole 123. Support 150 can provide support for cover body 140, avoiding the possibility of sagging of cover body 140 during the collection of material due to the gravity of the material, thereby improving the connection stability of cover body 140 and material bin 120.

[0041] Further, referring to Figure 4 And Figure 5 As shown, cover body 140 includes opposite closed end 1411 and open end 1412, and open end 1412 is used to connect support 150, so that accommodating cavity 141 can communicate with movable cavity 121 to realize the collection of material. Closed end 1411 is used to block the material from leaving cover body 140. Wherein, cover body 140 has a central axis, and the inner wall of open end 1412 is recessed to form groove 142, connecting channel 143 and opening 144 in the direction away from the central axis. Opening 144 extends to the edge of open end 1412 and leads through the edge of open end 1412. Groove 142 communicates with opening 144 through connecting channel 143. The outer wall of support 150 is protrusely provided with connecting part 151, connecting part 151 can enter the recessed structure of open end 1412 through opening 144, and the recessed structure is the structure formed by groove 142, connecting channel 143 and opening 144. Then connecting part 151 can be connected and fixed in groove 142 through connecting channel 143, thereby realizing the connection and fixation of support 150 and cover body 140.

[0042] Specifically, in this embodiment, when the cover 140 needs to be connected to the bracket 150, the connecting portion 151 of the bracket 150 needs to be aligned with the opening 144. Then, along a third direction, the cover 140 is slid relative to the bracket 150, allowing the connecting portion 151 to slide within the connecting channel 143. When the connecting portion 151 slides to the connection point between the connecting channel 143 and the groove 142, the cover 140 is rotated around its central axis, fixing the connecting portion 151 in the groove 142, thereby achieving a fixed connection between the bracket 150 and the cover 140. The groove 142, connecting channel 143, opening 144, and connecting portion 151 enhance the connection strength between the bracket 150 and the cover 140. Furthermore, since the connection and fixation of the cover 140 and the bracket 150 require sliding and rotation, that is, the connection between the opening 144 and the connecting channel 143 has a corner, the recessed structure of the open end 1412 will restrict the connecting part 151, so as to prevent the connecting part 151 from detaching from the recessed structure during the operation of the feeding assembly 100, which would cause the cover 140 and the bracket 150 to separate.

[0043] In some embodiments, see Figure 1 and Figure 2 As shown, the feed pipe 110 includes a first pipe body 112 and a second pipe body 113, which together define a feed channel 111. The first pipe body 112 is connected to the feed hopper 120 and communicates with the feed inlet 122. The second pipe body 113 is connected to the side of the first pipe body 112 away from the feed hopper 120. In this embodiment, the second pipe body 113 is disposed on the side of the first pipe body 112 away from the feed hopper 120 along a second direction. Connecting the second pipe body 113 in the second direction can increase the flow rate of the material in the feed channel 111, thereby improving the mixing efficiency of the material. In other embodiments, the second pipe body 113 may also be connected to the first pipe body 112 along a first direction, a third direction, or other directions.

[0044] Furthermore, the second tube 113 is inclined relative to the feed hopper 120. Specifically, it can be understood that the upper surface of the feed hopper 120 is a flat surface, and the plane where the second tube 113 is located has an angle of less than 90 degrees with the upper surface of the feed hopper 120. By inclining the second tube 113, the material can slide on the tube wall of the second tube 113, reducing the potential energy of the material and thus reducing the impact of the material on the side wall of the feed pipe 110, thereby extending the service life of the feed pipe 110. In addition, if part of the insert plate 130 is still located at the feed inlet 122 during the process of switching the insert plate 130 from the first position to the second position, allowing the material to slide along the tube wall of the second tube 113, it can also reduce the impact of the material on the insert plate 130 and protect the insert plate 130.

[0045] In some embodiments, referring to Figure 2 and Figure 3 As shown, the feeding bin 120 further comprises a partition 170 which divides the movable cavity 121 into a first chamber 1211 and a second chamber 1212 along a first direction, and the first chamber 1211 is communicated with the second chamber 1212 so that the plug plate 130 can move between the two chambers. The feeding port 122 is formed by the first chamber 1211 along a second direction, and the through hole 123 is formed by the second chamber 1212 along a third direction. When the plug plate 130 is in the first position, the plug plate 130 is arranged in the first chamber 1211 to close the feeding port 122, preventing the material from splashing and avoiding impurities entering the mixing cavity 210 through the feeding passage 111. When the plug plate 130 is in the second position, the plug plate 130 is arranged in the second chamber 1212 to avoid the material. By dividing the movable cavity 121 to form the first chamber 1211 and the second chamber 1212, the plug plate 130 can have different accommodation spaces at different positions, thereby reducing the possibility of deformation of the plug plate 130 caused by the impact of the material during feeding, and reducing the possibility that the plug plate 130 cannot completely close the feeding port 122 during mixing of the material.

[0046] In some embodiments, referring to Figures 1 to 5 As shown, the second chamber 1212 is formed with a plurality of through holes 123 which are connected to the cover body 140, i.e. each through hole 123 is covered by a separate cover body 140. The accommodation cavity 141 of the cover body 140 is communicated with the second chamber 1212 through the through hole 123. The total volume of the accommodation cavities 141 of the plurality of cover bodies 140 connected by the through holes 123 is greater than the volume of the second chamber 1212. Specifically, when the material is mixed, the plug plate 130 is arranged in the first chamber 1211 to close the feeding port 122, but there is still a gap between the feeding port 122 and the plug plate 130, and part of the gas in the mixing cavity 210 will overflow through the gap. However, since the plug plate 130 is accommodated in the first chamber 1211, and the first chamber 1211 and the second chamber 1212 are communicated, the gas will drift to the second chamber 1212 and fill the second chamber 1212. The drifted gas will mix with dust and various chemical raw materials, so that the total volume of the plurality of cover bodies 140 is greater than the volume of the second chamber 1212, which can dilute the drifted gas from the mixing cavity 210 by the air in the cover body 140, avoid the drifted gas being inhaled by the human body or drifting into the atmospheric environment, reduce the pollution of impurities to the environment and the harm of impurities to the human body. At the same time, the cover body 140 can collect impurities such as dust and chemical raw materials, to further reduce the pollution of impurities to the environment and the harm of impurities to the human body.

[0047] In some embodiments, referring to Figure 2and Figure 3 As shown, the feeding assembly 100 further comprises a scraper 180 connected to the partition 170 and arranged in the first chamber 1211. Specifically, in this embodiment, the scraper 180 is arranged at the end of the first chamber 1211 communicating with the second chamber 1212. When the plug plate 130 is switched between the first position and the second position, the scraper 180 abuts against both sides of the plug plate 130, i.e. the upper side and the lower side, in the first direction. Since the material is mixed, or the material enters the mixing cavity 210 through the feeding channel 111, part of the material will adhere to the plug plate 130. Since the material has the possibility of adhering to the wall of the feeding channel 111 when the material enters the mixing cavity 210, the feeding assembly 100 will produce a shaking when the material starts to mix, so that the material will fall on the plug plate 130. Arranging the scraper 180 in the first chamber 1211 can make the scraper 180 clean the material on the plug plate 130 when the plug plate 130 is moved from the first chamber 1211 to the second chamber 1212, avoid the situation that the plug plate 130 carries the material to the second chamber 1212, affects the movement of the plug plate 130 in the first direction, and reduces the situation that the material blocks the through hole 123. In other embodiments, the scraper 180 can also be arranged in the second chamber 1212, or arranged at the communication between the first chamber 1211 and the second chamber 1212.

[0048] In some embodiments, referring to Figure 3 As shown, the first chamber 1211 is formed with a fixed groove 124 for accommodating the plug plate 130 along the first direction to the feeding bin 120. The fixed groove 124 is arranged at the left side of the first chamber 1211 along the first direction, and the partition 170 is arranged at the right side of the first chamber 1211. When the plug plate 130 is switched from the second position to the first position, part of the plug plate 130 will be inserted into the accommodating groove, preventing the plug plate 130 from continuing to move in the first direction, so that the movement state of the plug plate 130 can be used to determine whether the plug plate 130 seals the feeding port 122. Moreover, since the plug plate 130 is accommodated in the fixed groove 124, the groove wall of the fixed groove 124 can provide support for the plug plate 130, avoiding the plug plate 130 from sagging under the action of gravity and affecting the sealing of the plug plate 130 to the feeding port 122. At the same time, the groove wall of the fixed groove 124 can also serve as a limiting function. When the material is mixed, the feeding assembly 100 will resonate with the mixing cavity 210 under the operation of the machine. The groove wall of the fixed groove 124 can avoid the plug plate 130 from moving relative to the feeding bin 120 under the vibration of the feeding assembly 100, causing the position of the plug plate 130 to deviate and fail to seal the feeding port 122.

[0049] The material mixing device 10 of the second aspect of the present application will be described below with reference to the accompanying drawings. Referring to Figures 1 to 6As shown, the material mixing device 10 comprises a bin body 200 and the feeding assembly 100 described in any of the above embodiments. The interior of the bin body 200 defines a mixing cavity 210 for accommodating and mixing the material. The feeding bin 120 is connected to the bin body 200, and the feeding opening 122 is communicated with the mixing cavity 210, so that the material can enter the mixing cavity 210 through the feeding channel 111 and the feeding opening 122.

[0050] Specifically, in another example, the feeding assembly 100 is arranged above the bin body 200 in the second direction. In other embodiments, the feeding assembly 100 can also be connected to the side of the bin body 200 in the first direction or the third direction. The feeding channel 111 and the feeding opening 122 of the feeding assembly 100 are communicated with the mixing cavity 210 of the bin body 200. When the material enters the feeding assembly 100 through the feeding channel 111, the material will reach the feeding opening 122 along the path of the feeding channel 111 and then enter the mixing cavity 210 through the feeding opening 122. The bin body 200 is provided with a rotating device, which can be arranged in the mixing cavity 210 to stir the material, or can be connected to the bin body 200 to drive the bin body 200 to rotate, so as to realize the mixing of the material in the mixing cavity 210.

[0051] The material mixing device 10 of the embodiment of the utility model can convey the material into the mixing cavity 210 through the movement of the plug-in plate 130, so as to mix the material. During the mixing process, the mixing of the material will cause the change of the air pressure in the mixing cavity 210. The air permeability of the material mixing device 10 can be improved through the through hole 123, so as to relieve the air pressure difference between the mixing cavity 210 and the atmospheric environment, thereby reducing the splashing of the material.
