[0002] Industrial automated feeding devices play a key role in modern manufacturing, which involves the use of automated control systems to achieve efficient and accurate material feeding processes.

[0015] The present invention has the following beneficial effects:

[0016] 1. The industrial automated feeding device realizes the self-rotation of the placement column inside the feeding frame by the cooperation of the rotating motor, the driving gear and the gear segment. During the rotation of the placement column, the piston rod inside the placement column reaches the bottom side of the pushing cylinder, and the discharge port coincides with the feeding port. At this time, the movable end of the pushing cylinder extends out and presses the piston rod. During the pressing of the piston rod, the material inside the storage cylinder is squeezed, so that the material inside the storage cylinder reaches the inside of the mixing device through the discharge port and the feeding port. Since several storage cylinders are opened on the surface of the placement column, different materials can be stored, and different materials can be added in sequence during the mixing process of the mixing device. By adding materials in sequence, the mixing time and speed can be adjusted as needed, so that each material can be mixed according to the best conditions, thereby improving the mixing effect and efficiency.

[0017] 2. The industrial automated feeding device, in the process of pushing the cylinder to drive the piston rod to descend, utilizes the cooperation of the first resistance block, the second resistance block, the pressing rod, the sliding plate and the release spring, so that the piston block can be quickly lowered when there is a certain distance between the piston rod and the piston block. In the process of the piston block descending, the gas between it and the piston rod is squeezed. Therefore, the squeezed gas pushes the material blocked on the inner wall of the material transfer pipe through the cooperation of the air intake pipe and the connecting pipe, thereby achieving the effect of pushing the material and accelerating the falling of the material as much as possible. Moreover, by setting a heat sealing plate, the material blocked on the inner wall of the material transfer pipe can be melted, and at the same time, the gas is used to further accelerate the falling of the material from the material transfer pipe, thereby reducing the possibility of the material blocking the material transfer pipe.

[0018] 3. The industrial automated feeding device, when the material placed in the storage cylinder is pushed into the mixing equipment by the piston rod, a small amount of material will remain at the bottom of the piston rod. When the cylinder drives the piston rod to descend, the first resistance block, the second resistance block, the pressing rod, the sliding plate and the release spring cooperate to make the piston block descend quickly when there is a certain distance between the piston rod and the piston block. During the descent of the piston block, the gas between the piston block and the piston rod is squeezed. Therefore, part of the gas reaches the inside of the rotary pressure relief valve through the gas pipeline, so that the rotary pressure relief valve is rotated by the gas. During the rotation, the rotary pressure relief valve pushes the material remaining at the bottom of the piston rod, reducing the possibility of material adhering to the bottom of the piston rod, and further improving the speed and efficiency of feeding.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Embodiment 1: This embodiment is intended to promote the solution of the problem that a plurality of materials need to be stirred and mixed inside a stirring device. However, the traditional method of adding materials is to put all the materials inside the stirring device at one time. Adding a large amount of materials at one time will increase the burden on the stirring device, increase wear and energy consumption, thereby shortening the service life of the equipment and increasing operating costs. Please refer to Figure 1 - Fig. 9An industrial automated feeding device comprises a stirring device 110 and a feeding frame 111 installed on the upper side of the stirring device 110, a placing column 112 for placing materials is rotatably installed inside the feeding frame 111, a plurality of storage cylinders 113 for storing different materials are provided inside the placing column 112, a feeding port 114 for feeding is provided on the side of the storage cylinder 113, a discharging port 115 for discharging is provided on the bottom side of the storage cylinder 113, a feeding port 120 for feeding is provided on the upper side of the stirring device 110, a material transfer pipe 121 is provided on the bottom side of the feeding frame 111, the material transfer pipe 121 is communicated with the feeding port 120, a piston rod 122 for extruding materials is movably cooperated inside the storage cylinder 113, a pushing cylinder 123 for pressing the piston rod 122 is installed on the upper side of the placing column 112, and a rotating motor 124 for driving the placing column 112 to rotate is installed inside the feeding frame 111.

[0031] A first support frame 125 for supporting a feeding frame 111 is installed on the upper side of the stirring device 110, and a second support frame 130 for supporting a pushing cylinder 123 is installed on the side of the feeding frame 111. A support platform 131 is installed inside the feeding frame 111, and a rotating motor 124 is installed inside the support platform 131, and a driving gear 132 is installed at the output end of the rotating motor 124. A slot 133 is provided inside the placing column 112, and the support platform 131 is rotatably engaged inside the slot 133. A tooth segment 134 is provided inside the slot 133, and the tooth segment 134 is meshed with the driving gear 132. During the start-up of the rotating motor 124, the tooth segment 134 and the driving gear 132 are used to cooperate to make the placing column 112 rotate inside the feeding frame 111. During the rotation of the placing column 112, the discharge port 115 overlaps and communicates with the material transfer pipe 121.

[0032] See Figure 1 , Figure 2 , Figure 3 and Figure 4In the specific implementation, the output end of the rotating motor 124 installed inside the feeding frame 111 rotates, and the output end of the rotating motor 124 cooperates with the driving gear 132 and the tooth segment 134 opened inside the placement column 112 to make the placement column 112 rotate. During the rotation of the placement column 112, the piston rod 122 inside the placement column 112 reaches the bottom side of the pushing cylinder 123, and the discharge port 115 coincides with the feeding port 120. By pushing the movable end of the cylinder 123 to extend and press the piston rod 122, the piston rod 122 is pressed. During the process, the material placed in the storage barrel 113 is squeezed, so that the material in the storage barrel 113 reaches the interior of the stirring device 110 through the cooperation of the discharge port 115 and the feeding port 120. Since a plurality of storage barrels 113 are opened on the surface of the placement column 112, different materials can be stored, and different materials can be added in sequence during the process of stirring the materials in the stirring device 110. By adding materials in sequence, the stirring time and speed can be adjusted as needed, so that each material can be mixed according to the optimal conditions, thereby improving the mixing effect and efficiency.

[0033] A one-way valve is a common valve body. There is usually a moving part such as a spring and a valve disc inside the one-way valve. When the fluid flows in the designed direction, the valve disc is pushed open to allow the fluid to pass. When the fluid tries to flow in the opposite direction, the valve disc will be pressed by the spring or closed with the help of fluid pressure, thereby preventing the backflow of the fluid. Its specific model, working principle and usage are well known to those skilled in the art and will not be elaborated here.

[0034] The stirring device 110 is usually a rotating blade, paddle, spiral or other shaped component. The stirrer is driven to rotate by a motor or other power device, thereby generating shear force and fluid flow to mix the materials in the container. The specific model, working principle and use method are well known to those skilled in the art and will not be described in detail here.

[0035] See Figure 1 , Figure 2 , Figure 3 and Figure 4In a specific implementation, a sealing ring is installed on the side of the storage barrel 113, and the sealing ring rotates with the inner wall of the feeding frame 111. The sealing ring is set to reduce the leakage of materials as much as possible. A feeding channel 230 is opened on the side of the feeding frame 111, and a one-way valve is installed inside the feeding channel 230. The one-way valve is set to reduce the backflow of materials reaching the inside of the storage barrel 113 as much as possible. During the rotation of the storage barrel 113, the feeding channel 230 overlaps and communicates with the feeding port 114, and the sealing ring is set at the entrance of the feeding port 114. During the process that the feeding channel 230 overlaps and communicates with the feeding port 114, the inside of the storage barrel 113 can be replenished. Since different pastes need to be mixed, using the same feeding channel 230 for several storage barrels 113 will not affect the mixing.

[0036] See Figure 1 , Figure 2 , Figure 7 and Figure 8 A plurality of fan-shaped elastic sheets 141 are installed at the outlet of the discharge port 115. The elastic sheets 141 are arranged in a ring array inside the discharge port 115. When the plurality of elastic sheets 141 are squeezed, through holes for material flow will be formed in the middle of the plurality of elastic sheets 141. When the squeezing of the plurality of elastic sheets 141 is lost, the plurality of elastic sheets 141 are reset to seal the discharge port 115.

[0037] In this embodiment: through the cooperation of the rotating motor 124, the driving gear 132 and the gear segment, the placing column 112 is self-rotated inside the feeding frame 111. During the rotation of the placing column 112, the piston rod 122 inside the placing column 112 reaches the bottom side of the pushing cylinder 123, and the discharge port 115 coincides with the feeding port 120. At this time, the movable end of the pushing cylinder 123 extends out and presses the piston rod 122. During the pressing of the piston rod 122, the material inside the storage barrel 113 is squeezed, so that the material inside the storage barrel 113 reaches the inside of the mixing device 110 through the discharge port 115 and the feeding port 120. Since several storage barrels 113 are opened on the surface of the placing column 112, different materials can be stored, and different materials are added in sequence during the mixing process of the mixing device 110. By adding materials in sequence, the mixing time and speed can be adjusted as needed, so that each material can be mixed according to the optimal conditions, thereby improving the mixing effect and efficiency.

[0038] Embodiment 2: This embodiment is intended to promote the solution of the problem that in the process of feeding the paste material, due to the poor fluidity of the paste material, the paste material will be blocked inside the pipe during the feeding process, so that the material cannot flow smoothly into the stirring device 110, causing the stirring device 110 to operate poorly, thereby reducing the mixing efficiency and affecting the uniformity of the product. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1 - Fig. 9 A piston block 150 is movably fitted inside the storage cylinder 113, an annular block 151 is installed on the inner wall of the storage cylinder 113, a return spring 152 is installed between the annular block 151 and the piston block 150, the piston block 150 is slidably fitted with the rod portion of the piston rod 122, and a one-way valve is installed on the surface of the piston block 150.

[0039] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Fig. 9 An air intake pipe 153 is provided inside the piston rod 122, a heat-sealed plate 154 for melting materials is installed on the inner wall of the material transfer pipe 121, a sealing ring is installed on the movable end of the pushing cylinder 123, and an air transfer pipe 160 is provided inside the movable end of the pushing cylinder 123. In the process of the pushing cylinder 123 pushing the piston rod 122 to move, the movable end of the pushing cylinder contacts the upper end of the piston rod, so the air intake pipe 153 is communicated with the air transfer pipe 160, an annular pipe 161 is provided on the inner wall of the material transfer pipe 121, a connecting pipe 162 is installed between the annular pipe 161 and the air transfer pipe 160, a one-way valve is installed at the connection between the air intake pipe 153, the annular pipe 161 and the connecting pipe 162, a plurality of through holes are provided on the side of the annular pipe 161, and the plurality of through holes are arranged at an angle, so that the direction of gas blowing is also inclined.

[0040] The heat sealing plate 154 is a common preheating device, which is used in this embodiment to preheat the edge of the paste material, minimize the blockage of the paste material inside the pipeline, and increase the discharge speed. Its specific model, working principle and usage are well known to technicians in this field and will not be elaborated here.

[0041] A sliding groove 170 is provided on the rod portion of the piston rod 122, and a sliding plate 171 is slidably fitted inside the sliding groove 170, a push spring 172 is installed between the sliding plate 171 and the sliding groove 170, a vertical groove 173 is provided on the side of the sliding plate 171, a pressing rod 174 is slidably installed inside the vertical groove 173, a release spring 175 is installed between the pressing rod 174 and the vertical groove 173, a cylindrical groove 180 is provided inside the pressing rod 174, an insertion rod 181 is installed inside the vertical groove 173, and the insertion rod 181 and the cylindrical groove 180 are movably interlaced.

[0042] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and 9A first resistance block 190 is installed on the side of the annular block 151, and a second resistance block 191 is installed on the side of the pressing rod 174. In the process of pushing the cylinder 123 to push the piston rod 122 to move, the first resistance block 190 restricts the second resistance block 191, so as to restrict the movement of the pressing rod 174, and the cylinder 123 continues to push the piston rod 122 to move. Therefore, the first resistance block 190 and the second resistance block 191 are instantly offset, and the pressing rod 174 loses its restriction and is released to press the piston block 150. During the movement of the piston block 150, the gas between it and the piston rod 122 is squeezed. Therefore, the gas pushes the material blocked by the inner wall of the material transfer pipe 121 through the cooperation of the air intake pipe 153 and the connecting pipe 162.

[0043] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and 9 In a specific implementation, when the push cylinder 123 pushes the piston rod 122 downward, the sliding plate 171 and the pressing rod 174 installed on its side move together. During the movement, the second contact block 191 installed on the side of the pressing rod 174 contacts the first contact block 190, so that the first contact block 190 restricts the second contact block 191. Therefore, when the piston rod 122 descends, the sliding plate 171 slides to the end of the sliding groove 170, and the insertion rod 181 is inserted into the cylindrical groove 180. At this time, the pushing spring 172 and the release spring 175 are in a contracted state. As the piston rod 122 continues to descend, the first contact block 190 and the second contact block 1 91 is offset instantly, the pressing rod 174 loses its restriction and drops rapidly by releasing the push spring 172 and the release spring 175, and at the same time, the pressing rod 174 presses the piston block 150, so that the gas between the piston block 150 and the piston rod 122 is squeezed during the movement of the piston block 150, and in the process of the piston block 150 squeezing the gas between the piston rod 122, the gas uses the cooperation of the air intake pipe 153 and the connecting pipe 162 to blow the material blocked on the inner wall of the material transfer pipe 121, and at the same time, the heat sealing plate 154 is provided to melt the material blocked on the inner wall of the material transfer pipe 121, and the possibility of the material blocking the material transfer pipe 121 is reduced by blowing and melting the material.

[0044] It should be noted that, in the process of a small amount of material being squeezed to reach the interior of the mixing equipment 110, the setting of the heat sealing plate 154 will melt the material inside the material transfer pipe 121, causing the material to fall into the mixing equipment 110. However, in the process of a large amount of material being squeezed to reach the interior of the mixing equipment, a single heat sealing plate 154 is not sufficient to handle the large amount of material. Therefore, gas is needed to push the material to reduce the possibility of material blockage and at the same time speed up the material falling speed.

[0045] In this embodiment: when the pushing cylinder 123 drives the piston rod 122 to descend, the cooperation of the first resistance block 190, the second resistance block 191, the pressing rod 174, the sliding plate 171 and the release spring 175 can be used to make the piston block 150 descend quickly when there is a certain distance between the piston rod 122 and the piston block 150. During the descending process of the piston block 150, the gas between it and the piston rod 122 is squeezed. Therefore, the squeezed gas pushes the material blocked on the inner wall of the material transfer pipe 121 through the cooperation of the air intake pipe 153 and the connecting pipe 162, thereby achieving the effect of pushing the material and accelerating the falling of the material as much as possible. Moreover, by setting the heat sealing plate 154, the material blocked on the inner wall of the material transfer pipe 121 can be melted. At the same time, by utilizing the push of gas, the falling of the material from the material transfer pipe 121 is further accelerated, reducing the possibility of material blocking the material transfer pipe 121.

[0046] Embodiment 3: This embodiment is intended to solve the problem that after all the materials in the storage cylinder 113 are discharged, some of the materials may remain at the bottom of the piston rod 122. The materials adhering to the bottom of the piston rod 122 may be difficult to clean, requiring additional manual or mechanical cleaning work, which increases the complexity and time cost of maintenance. This embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figure 1 - Fig. 9 A connecting groove 210 is formed on the inner wall of the storage tube 113 , a third resisting block 211 is movably installed inside the connecting groove 210 , and a first spring 212 is installed between the third resisting block 211 and the connecting groove 210 .

[0047] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 8 In a specific implementation, the movement of the piston block 150 can be limited by the cooperation between the connecting groove 210 and the third resistance block 211 and the first spring 212, so that when the piston rod 122 squeezes the material again, there is a certain distance between the piston block 150 and the piston rod 122, thereby realizing a new round of gas squeezing.

[0048] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 8 An air pipeline 222 is provided inside the piston rod 122, a rotary pressure relief valve 220 is installed on the bottom side of the piston rod 122, the air pipeline 222 is communicated with the rotary pressure relief valve 220, and an air outlet for blowing off the material at the end of the piston rod 122 is provided on the side of the rotary pressure relief valve 220.

[0049] It should be noted that when there is material inside the storage cylinder 113, the squeezed gas will be restricted by the material, so the gas will flow out from the air inlet pipe 153; when the material inside the storage cylinder 113 is squeezed, the material loses the restriction of the gas pipeline 222 on the rotary pressure relief valve 220, so the gas will flow from the gas pipeline 222 into the rotary pressure relief valve 220. It should also be noted that the gas between the piston block and the piston rod is not only sufficient to push the material at the end of the piston rod 122, but also can push the material blocked in the material transfer pipe 121.

[0050] The rotary pressure relief valve 220 is a valve that uses rotational motion to control gas pressure relief. In this embodiment, the rotary pressure relief valve 220 is used to rotate and release gas when the gas reaches the inside of the rotary pressure relief valve 220, so that the gas pressure pushes the material at the end of the piston rod 122.

[0051] In specific implementation, after the material placed inside the storage cylinder 113 is pushed into the mixing device 110 by the piston rod 122, a small amount of material will adhere to the bottom end of the piston rod 122. When the pushing cylinder 123 drives the piston rod 122 to descend, the cooperation of the first resistance block 190, the second resistance block 191, the pressing rod 174, the sliding plate 171 and the release spring 175 can be used to make the piston block 150 descend quickly when there is a certain distance between the piston rod 122 and the piston block 150. During the descent of the piston block 150, the gas between it and the piston rod 122 is squeezed. Therefore, part of the gas reaches the inside of the rotary pressure relief valve 220 through the gas pipeline 222, so that the rotary pressure relief valve 220 is rotated by the gas. During the rotation, the rotary pressure relief valve pushes the material remaining at the bottom of the piston rod 122, thereby reducing the possibility of material adhering to the bottom end of the piston rod 122 and improving the efficiency of feeding.

[0052] In this embodiment: after the material placed in the storage cylinder 113 is pushed into the mixing device 110 by the piston rod 122, a small amount of material will remain at the bottom of the piston rod 122. When the cylinder 123 drives the piston rod 122 to descend, the first resistance block 190, the second resistance block 191, the pressing rod 174, the sliding plate 171 and the release spring 175 cooperate to make the piston block 150 descend quickly when there is a certain distance between the piston rod 122 and the piston block 150. During the descent of the piston block 150, the gas between it and the piston rod 122 is squeezed. Therefore, part of the gas reaches the inside of the rotary pressure relief valve 220 through the gas pipeline 222, so that the rotary pressure relief valve 220 is rotated by the gas. During the rotation, the rotary pressure relief valve pushes the material remaining at the bottom of the piston rod 122, thereby reducing the possibility of material adhering to the bottom of the piston rod 122, and further improving the speed and efficiency of feeding.
