When production volume is high, at least 6 people are needed to ensure production. Two groups of people work back and forth between mixing, unloading, and weighing. Due to human fatigue, the longer the production time, the lower the efficiency of manual labor becomes. In order to meet the deadline, more people are needed, which leads to high labor costs in project production. Summary of the Invention Utility Model Content

[0025] This specific embodiment is an automated material discharging and weighing device for PCM phase change material production, and its structural schematic diagram is shown below. Figures 1-5As shown, the automated material feeding and weighing device for PCM phase change material production includes a gantry crane 1, a raw material tank 2, a material cylinder transfer machine 4, a feeding mechanism 8, a dumping operation platform 9, and an electrical control box 12. The gantry crane 1 is used to transfer materials. The raw material tank 2 is used to hold raw material powder. A stirring mechanism 3 is installed on the raw material tank 2 to prevent uneven distribution of raw material powder after it enters the raw material tank 2. An intermittent feeding mechanism 13 is installed on the raw material tank 2. An intelligent quantitative scale 5 is installed inside the material cylinder transfer machine 4. A loading bucket 6 for receiving raw material powder is placed on the intelligent quantitative scale 5. A movable wooden pallet 7 is placed inside the material cylinder transfer machine 4. The movable wooden pallet 7 is used to place the loading bucket 6 filled with raw material powder. The feeding mechanism 8 is used to transport the raw material powder in the raw material tank 2 to the loading bucket 6. The dumping operation platform 9 is used to dump the material. The electrical control box 12 is used to control the operation of the raw material tank 2, the stirring mechanism 3, the material cylinder transfer machine 4, the intelligent quantitative scale 5, the feeding mechanism 8, and the intermittent feeding mechanism 13.

[0026] A ladder 10 is fixedly installed on the side of the material pouring operation platform 9 away from the raw material tank 2. A protective net is installed on the outside of the ladder 10. The protective net is fixedly installed on both sides of the material pouring operation platform 9. A guardrail 11 is fixedly installed on the top of the material pouring operation platform 9. Production personnel climb to the top of the material pouring operation platform 9 by climbing the ladder 10. The guardrail 11 provides safety protection for production personnel when working on the top of the material pouring operation platform 9. At the same time, the protective net provides protection for production personnel when climbing or descending on the ladder 10.

[0027] The stirring mechanism 3 includes a drive motor 301 fixedly installed on the top of the raw material tank 2 and a stirring roller 302 disposed inside the raw material tank 2. The top end of the stirring roller 302 passes through the raw material tank 2 and is fixedly connected to the output end of the drive motor 301. The top of the raw material tank 2 is provided with a discharge port for discharging material. A cover plate 201 is hinged to the top of the raw material tank 2. An inspection port is provided on the top of the raw material tank 2. An inspection door is detachably installed on the inspection port, for example, by screw installation. A cone 202 is fixedly installed inside the raw material tank 2. A discharge port 203 is provided on the cone 202. A material sensor 204 is installed at the corresponding position of the cone 202 and the discharge port 203. An airlock discharge valve 205 is installed at the discharge port 203. The drive motor 301 drives the stirring roller 302 to rotate, which can stir the raw material powder inside the raw material tank 2.

[0028] First, the raw material package is placed directly above the discharge port of the raw material tank 2 by the overhead crane 1 in the workshop. Production personnel cut open the woven bag on the discharge operation platform 9 and pour the raw material powder into the raw material tank 2. During the discharge, the intelligent quantitative weighing 5 of the entire automated discharge and weighing device is in a state of automatic shutdown, but can be manually started manually. The cylinder of the raw material tank 2 is made of SUS304 material, and the inner wall is made of smooth surface to reduce friction and ensure smooth discharge of raw material powder. At the same time, since the discharge port is operated on one side, the raw material powder will be uneven after entering the tank. Therefore, the stirring mechanism 3 is manually activated separately during the discharge to stir the raw material powder so that it is evenly distributed after entering the tank, thereby allowing more raw material powder to be loaded. At the same time, the airlock discharge valve 205 of the discharge port 203 is closed during the discharge, and the material sensor 204 is also closed to avoid triggering the alarm.

[0029] The intermittent feeding mechanism 13 includes a feeding hopper 1301 fixedly installed on the inner wall of one side of the raw material tank 2, a discharge outlet 1302 opened at the middle position of the bottom end of the feeding hopper 1301, a baffle 1303 slidably installed on the bottom of the feeding hopper 1301, a protective shell 1304 fixedly installed on the feeding hopper 1301, a motor 1305 fixedly installed on the inner top wall of the protective shell 1304, a rotating rod 1306 fixedly installed on the output end of the motor 1305, and a half tooth fixedly installed on the end of the rotating rod 1306 away from the motor 1305. The wheel 1307, the loop frame 1308 slidably installed on the feed hopper 1301, and the two racks 1309 fixedly installed on the inner walls of the front and rear sides of the loop frame 1308 are connected by the half gear 1307 and the rack 1309. The protective shell 1304 is a U-shaped shell, which can protect the motor 1305, the rotating rod 1306, the half gear 1307, the loop frame 1308 and the rack 1309, so that they are located in a closed space. The bottom opening of the protective shell 1304 slides in contact with the bottom of the baffle 1303.

[0030] Two sliding rods 1310 are fixedly installed on the feed hopper 1301. The inner walls of the front and rear sides of the U-shaped frame 1308 are provided with sliding grooves that cooperate with the sliding rods 1310. The ends of the two sliding rods 1310 that are far apart extend into the interior of the two sliding grooves respectively. The maximum sliding distance of the sliding rods 1310 in the sliding grooves in the direction away from the feed hopper 1301 is greater than the length of the sliding groove. This setting can ensure that the U-shaped frame 1308 will not detach from the sliding rods. The bottom of the two racks 1309 are fixedly connected with L-shaped connecting rods 1311. The end of the L-shaped connecting rod 1311 that is away from the rack 1309 is fixedly connected to the baffle 1303. With the cooperation of the sliding grooves and sliding rods 1310, the racks 1309, L-shaped connecting rods 1311 and baffle 1303 can be supported, and the movement of the racks 1309, L-shaped connecting rods 1311 and baffle 1303 can be guided.

[0031] When the raw material powder is poured into the raw material tank 2, it first enters the inside of the feed hopper 1301. The motor 1305 is started to drive the rotating rod 1306 and the half gear 1307 to rotate. During the rotation of the half gear 1307, it can drive the rack 1309 located behind it to contact, causing the rack 1309 to move away from the discharge outlet 1302. During the movement of the rack 1309, it can drive the loop frame 1308 to move away from the discharge outlet 1302. During the movement of the loop frame 1308, it can drive the L-shaped connecting rod 1311 and the baffle 1303 to move away from the discharge outlet 1302. During the movement of the baffle 1303 away from the discharge outlet 1302, the bottom of the baffle 1303 slides against the inner bottom wall of the protective shell 1304. The material is fed into the feed hopper 1301 until it leaks out of the feed outlet 1302, allowing the powder material inside the feed hopper 1301 to enter the raw material tank 2 through the feed outlet 1302. When the half gear 1307 no longer contacts the rack 1309 behind it, it will mesh with the rack 1309 in front of it, causing the rack 1309 to move towards the feed outlet 1302. During the movement of the rack 1309, it can drive the loop frame 1308 to move towards the feed outlet 1302. During the movement of the loop frame 1308, it can drive the L-shaped connecting rod 1311 and the baffle 1303 to move towards the feed outlet 1302 until the baffle 1303 blocks the feed outlet 1302. At this time, under the action of the baffle 1303, the raw material powder inside the feed hopper 1301 will no longer be fed.

[0032] Therefore, the intermittent feeding mechanism 13 enables the intermittent feeding of raw material powder, which can minimize the accumulation of powder raw materials inside the raw material tank 2.

[0033] The airlock discharge valve 205 is existing technology, and its specific structure will not be described in detail here. For example, this utility model uses a rotary discharge valve (rotary valve), which is commonly used for powdery and granular materials (such as cement, flour, and plastic granules). The raw material powder processed by this system happens to be in powdery and granular form. To ensure safety, a valve with explosion-proof, high-temperature resistant, and wear-resistant design is selected.

[0034] When pouring raw materials into raw material tank 2, the airlock discharge valve 205 must be closed to prevent leakage. Raw material tank 2 must be filled before the production line can operate continuously. The airlock discharge valve 205 can also control the discharge. During the stage of pouring raw material powder into raw material tank 2, the airlock discharge valve 205 is in the closed state. Only when the system is turned on to automatic and in the automatic material discharging and weighing stage will the airlock discharge valve 205 open. At the same time, during the alarm shutdown or manual shutdown stage of the system, the airlock discharge valve 205 will be closed.

[0035] The feeding mechanism 8 is a screw conveyor. The feed inlet of the screw conveyor is connected to the discharge outlet 203. The screw conveyor passes through the cone 202 and the raw material tank 2 and extends to the outside of the raw material tank 2. The discharge outlet of the screw conveyor is located above the intelligent quantitative scale 5. The screw conveyor includes a housing, a screw shaft rotatably installed inside the housing, screw blades fixedly installed on the screw shaft, and a motor fixedly installed on the housing for driving the screw shaft to rotate. The feed inlet is opened at one end of the housing, and the discharge outlet is opened at the other end of the housing.

[0036] After the raw material tank 2 is filled with raw material powder and the loading bucket 6 above the intelligent quantitative weigher 5 is ready, the production personnel turn off the equipment that was started by jogging in the electrical control system of the electrical control box of this device, adjust the manual to automatic mode and start the operation; the stirring mechanism 3 of the raw material tank 2 works to ensure uniform feeding, the material sensor 204 is energized, and it monitors the raw material powder inside the raw material tank 2 at all times (if the raw material powder is lower than the material sensor 204, after the material sensor 204 detects the data, the light will turn off the alarm and the control system will prompt that the powder is empty; if the replenishment and reset operation is not performed at this time, the entire system will be delayed). The machine stops after 2 minutes (the delay ensures that the raw material in the discharge port 203 of the raw material tank 2 and the screw conveyor are emptied). The airlock discharge valve 205 opens, and the material is discharged into the screw conveyor inlet. The screw conveyor is set at a 40° inclination. The screw conveyor motor starts, and the drive unit runs. The screw rotates continuously, pushing the raw material powder to the screw conveyor outlet. The raw material powder falls into the filling hopper 6 through the outlet. The intelligent quantitative scale 5 at the bottom of the filling hopper 6 monitors the weight of the raw material powder inside the filling hopper 6 in real time. The intelligent quantitative scale 5 transmits the data to the PLC through a signal line, and simultaneously... The data is displayed on the control box screen. The intelligent quantitative scale 5 is linked with the PLC control (mainly by adding a PLC analog module, and the electrical control system adds a signal line to receive data from the intelligent quantitative scale 5 to achieve limited transmission. After adding the PLC analog module, an electrical engineer can program the logic and interlocking framework on a computer and import it into the electrical control system, where parameters can be set and modified). When the data transmitted by the intelligent quantitative scale 5 is close to the remaining 10% of the set required weight (this data can be set in the system), the frequency converter of the screw conveyor drive device installed in the control system automatically adjusts the frequency converter, which can slow down the rotation speed of the screw conveyor, reduce the output, and reduce the weighing error. When the data transmitted by the intelligent quantitative scale to the control system reaches the specified data, the light turns off and the alarm sounds. The stirring mechanism 3 on the raw material tank 2 and the screw conveyor both stop working, and the airlock discharge valve 205 closes. The weight of the raw material powder is allowed to have an error of less than 3%. If the weight is greater than this value, the alarm will continue, and the weight needs to be adjusted manually. If there is a certain error in the output of the screw conveyor, the corresponding error can be reduced by the above methods.

[0037] The material cylinder transfer machine 4 includes two tracks 401. Support columns 402 are fixedly installed at both ends of the bottom of each track 401. A pulley 403 is slidably installed on the track 401. A bracket 404 is installed and connected on the pulley 403. A barrel ear buckle 405 is fixedly installed on the connecting bracket 404.

[0038] To transfer the filling barrel 6 filled with raw material powder from the intelligent quantitative weighing scale 5 to a designated location while minimizing the physical labor of production personnel, a barrel transfer machine 4 is provided for auxiliary transfer. When the filling barrel 6 is placed on the intelligent quantitative weighing scale 5, the barrel ear buckles 405 are fixed on the barrel ears on both sides of the filling barrel 6. When the weight of the filling barrel 6 meets the requirements, the production personnel will manually push and pull the connecting bracket 404. The connecting bracket 404 slides on the track 401 through the pulley 403. During the sliding process, the connecting bracket 404 drives the filling barrel 6 to move, thereby moving the filling barrel 6 onto the movable wooden pallet 7. When the movable wooden pallet 7 is full of filling barrel 6, a forklift can be used to transfer the movable wooden pallet 7 and the filling barrel 6 on the movable wooden pallet 7.

[0039] The entire process described above, from material weighing and material handling, can be completed by just one person. To improve overall efficiency, one additional person can be added to transfer the raw materials from the woven bags to the raw material tank 2 via the overhead crane 1.

[0040] The material sensor 204 of this utility model can be selected from vibrating rod level switches, capacitive level switches, tuning fork level switches, etc. The vibrating rod of the vibrating rod level switch is excited by an electronic circuit and maintains resonance. When the measured medium reaches and partially covers the probe of the vibrating rod switch, the vibration damping of the vibrating rod switch suddenly increases. This change in vibration parameters will trigger a relay through the detection circuit, thereby providing upper and lower limit switch signals for level control.

[0041] Capacitive level switches utilize a sensing rod (electrode) with the material as the medium. The capacitance between the sensing rod and the tank wall (ground electrode) increases as the sensing rod is covered by material. When the material reaches the set matching value of the switch's internal circuit, the circuit generates high-frequency resonance, detects the resonance signal, and converts it into a switching signal.

[0042] A screw conveyor is a machine that uses a motor to drive a rotating screw to push materials for conveying purposes. It can convey horizontally, inclined, or vertically, and has advantages such as simple structure, small cross-sectional area, good sealing, convenient operation, easy maintenance, and convenient enclosed transportation. Shafted screw conveyors are suitable for non-sticky dry powder materials and small granular materials (e.g., cement, fly ash, lime, grain, etc.), so they are suitable for the raw material powders that this invention needs to process. Its working principle is that the rotating screw blades push the material for conveying. The force that prevents the material from rotating with the screw conveyor blades is the material's own weight and the frictional resistance of the screw conveyor casing against the material. The screw blades welded to the rotating shaft of the screw conveyor have different surface shapes depending on the material being conveyed, such as solid surface, ribbon surface, and blade surface. The screw conveyor of this invention is installed at an incline and adopts the form of a shafted screw conveyor.

[0043] In summary, this automated material feeding and weighing device for the production of PCM phase change materials directly replaces the existing manual operations of mixing, feeding, and weighing. It essentially eliminates the physical labor of production personnel in this stage, resulting in higher efficiency and lower labor costs in both the long and short term. The entire process, from feeding, weighing, and transferring materials, can be completed by only one person. If we want to improve the overall efficiency, we only need to add one person to be responsible for cutting open the woven bags and dumping the materials when transferring the raw materials from the woven bags to the raw material tank 2 via the overhead crane 1.

[0044] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
