Description

Technical Field

[0001] This utility model relates to the field of packaging technology, specifically to a fully enclosed automated grading and packaging equipment for zinc oxide. Background Technology

[0002] Zinc oxide, a common inorganic compound, is widely used in industries such as rubber, plastics, coatings, and pharmaceuticals. Fully enclosed automated grading and packaging equipment for zinc oxide is an industrial device specifically designed for packaging zinc oxide and other powdered or granular materials. This machine enables fully automated grading processing from material supply, weighing, dispensing to sealing, improving packaging efficiency and ensuring packaging quality.

[0003] During grading, because zinc oxide is in powder form, simply placing the packaging bag under the discharge hopper will cause the zinc oxide powder to fly around, polluting the working environment. Therefore, operators need to wrap the packaging bag tightly at the discharge pipe and wait for the discharge to complete before moving it to the next area for processing. When loading zinc oxide material, two people need to cover the packaging bag at the discharge hopper and keep it fixed there until the material is discharged. Moreover, if the worker does not hold it tightly enough or the zinc oxide material is too heavy, the zinc oxide material may spill out during loading, resulting in uneven filling of each packaging bag. This requires weighing and adding more material later, which also pollutes the working environment and requires manual cleaning afterward. Furthermore, when zinc oxide powder falls onto the machinery, it may cause blockages and mechanical failures. Utility Model Content

[0004] This invention proposes a fully enclosed automated grading and packaging equipment for zinc oxide, which solves the problem in the prior art where zinc oxide material spills outside the packaging bag when the bag is not properly secured or when the material is overloaded during manual bag fixing, resulting in uneven bagging and pollution of the working environment.

[0005] The technical solution of this utility model is as follows:

[0006] A fully enclosed automated grading and packaging device for zinc oxide includes an inlet hopper and an outlet hopper. The bottom of the outlet hopper is connected to the bottom of the inlet hopper, and a support rod is fixedly connected to the outermost wall of the highest point of the outlet hopper. The device also includes:

[0007] The baffle is fixedly connected to both ends of the support rod to prevent zinc oxide from flying out during discharge;

[0008] The clamping mechanism is provided on the outer side wall of the baffle to clamp the packaging bag waiting for zinc oxide to be loaded.

[0009] A lifting mechanism is provided on the side of the feeding hopper away from the clamping mechanism, and is used to lift the packaging bag.

[0010] A fixing mechanism is provided on the lifting mechanism for opening the packaging bag.

[0011] Preferably, the clamping mechanism includes:

[0012] An electric cylinder is mounted on the outer wall of the baffle.

[0013] A push rod is fixedly connected to the output end of the electric cylinder;

[0014] The gripper is fixedly connected to the other end of the push rod.

[0015] Preferably, the lifting mechanism includes:

[0016] The bracket is fixedly connected to the end of the feed hopper away from the limiting rod;

[0017] A lifting area is located in the middle of the bracket;

[0018] A fixed base is fixedly connected to one end of the lifting area facing the discharge barrel, and a fixing port is provided on the fixed base;

[0019] A transmission seat is fixedly connected to the top of the lifting area. The transmission seat has a swivel opening at one end facing the fixed seat, and a motor is installed on the top of the transmission seat.

[0020] A reciprocating lead screw, one end of which extends into a rotary port and is fixedly connected to the output end of the motor, and the other end of which is rotatably connected to the fixed port;

[0021] Nut seat, which is threadedly connected to the reciprocating lead screw.

[0022] Preferably, the fixing mechanism includes:

[0023] The fixing rod is fixedly connected to both ends of the nut seat;

[0024] A retaining ring is fixedly connected to one end of each of the two retaining rods away from the nut seat;

[0025] A spring, wherein the two ends of the retaining ring are fixedly connected to the spring;

[0026] The clamp is fixedly connected to the other end of each spring.

[0027] Preferably, the curvature of the gripper is the same as the curvature of the discharge bucket.

[0028] Preferably, a limit plate is slidably connected to the reciprocating lead screw.

[0029] The working principle and beneficial effects of this utility model are as follows:

[0030] In this invention, when packaging zinc oxide material, the packaging bag is first fixed in place by a fixing mechanism. Then, a lifting mechanism is activated, which drives the fixing mechanism to slide up and down, thus fixing the packaging bag. Next, a clamping mechanism clamps the packaging bag onto the discharge hopper, allowing the discharge hopper to discharge zinc oxide material into the packaging bag. Once the packaging bag is full of zinc oxide material, the clamping mechanism is released, and the full packaging bag is moved to a designated position to await the next operation. Compared to existing technologies, this invention allows the packaging bag to rise and be fixed onto the discharge hopper automatically, saving manpower. Furthermore, using a clamping mechanism to hold the packaging bag onto the discharge hopper effectively prevents zinc oxide material from spilling out of the packaging bag during loading, thus avoiding pollution of the working environment and preventing zinc oxide material from scattering on the equipment, reducing equipment blockage and mechanical failures.

[0037] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0038] like Figures 1-4 As shown in the figure, this embodiment proposes a fully enclosed automated grading and packaging equipment for zinc oxide, including a feeding tank 1 and a discharging tank 2. The bottom of the discharging tank 2 is connected to the feeding tank 1, and a support rod 4 is fixedly connected to the outer wall of the highest point of the discharging tank 2. It also includes baffles 6, clamping mechanisms, lifting mechanisms, and fixing mechanisms. Baffles 6 are fixedly connected to both ends of the support rod 4 to prevent zinc oxide from flying out during discharging. Clamping mechanisms are provided on the outer walls of the baffles 6 to clamp the packaging bags waiting for zinc oxide to be loaded. The lifting mechanism is located on the side of the feeding tank 1 away from the clamping mechanism and is used to lift and lower the packaging bags. The fixing mechanism is set on the lifting mechanism to open the packaging bag. The baffle 6 is made of transparent material to facilitate observation of the filling process and timely handling of any problems. It also prevents dust raised by the zinc oxide material during discharge from polluting the working environment. It should be noted that the feeding hopper 1 is funnel-shaped and has a feeding port 3 at the top. A limit rod 5 is fixedly connected to the support rod 4. The zinc oxide material can slide from the feeding port 3 of the funnel-shaped feeding hopper 1 into the packaging bag. The packaging bag filled with zinc oxide material will slide to a designated position for collection via the limit rod 5.

[0039] In this embodiment, the clamping mechanism includes an electric cylinder 101, a push rod 102, and a gripper 103. The electric cylinder 101 is fixedly installed on the outer wall of the baffle 6. The push rod 102 is fixedly connected to the output end of the electric cylinder 101. The gripper 103 is fixedly connected to the other end of the push rod 102. The curvature of the gripper 103 is the same as the curvature of the discharge barrel 2. This is mainly to ensure that the packaging bag is tightly wrapped around the discharge barrel 2, so that the packaging bag does not slip off the discharge barrel 2 and the material is loaded more effectively.

[0040] In this embodiment, the lifting mechanism includes a bracket 201, a lifting area 202, a fixed seat 203, a transmission seat 205, a motor 206, a reciprocating screw 207, and a nut seat 208. The bracket 201 is fixedly connected to the end of the feed hopper 1 away from the limiting rod 5. The lifting area 202 is located in the middle of the bracket 201. The fixed seat 203 is fixedly connected to the end of the lifting area 202 facing the discharge hopper 2, and a fixing port 204 is provided on the fixed seat 203. The transmission seat 205 is fixedly connected to the top of the lifting area 202, and the transmission seat 205 faces the fixed seat 203. One end of the transmission seat 205 has a turnout, and a motor 206 is mounted on the top of the transmission seat 205. One end of the reciprocating screw 207 extends into the turnout and is fixedly connected to the output end of the motor 206. The other end of the reciprocating screw 207 is rotatably connected to the fixed port 204. The nut seat 208 is threadedly connected to the reciprocating screw 207. A limit plate 7 is slidably connected to the reciprocating screw 207 to limit the lifting area of ​​the nut seat 208 and prevent the nut seat 208 from sliding out of the range of the transmission seat 205. Moreover, when the sliding range needs to be adjusted, the height of the limit plate 7 can be directly adjusted.

[0041] In this embodiment, the fixing mechanism includes a fixing rod 301, a fixing ring 302, a spring 303, and a clamping plate 304. The fixing rods 301 are fixedly connected to both ends of the nut seat 208. The fixing rings 302 are fixedly connected to the ends of the two fixing rods 301 away from the nut seat 208. The springs 303 are fixedly connected to both ends of the fixing rings 302. The clamping plate 304 is fixedly connected to the other end of each spring 303. The springs 303 are positioned above the fixing rings 302 and the clamping plate 304. When the packaging bag is clamped, it is clamped below the springs 303.

[0042] In summary, the working principle of this fully enclosed automated grading and packaging equipment for zinc oxide is as follows: When packaging zinc oxide materials, the worker first places a stack of neatly arranged packaging bags in an open position at the bottom of the discharge hopper 2. At this time, the fixing ring 302 is above the packaging bags. The motor 206 is started, causing the reciprocating screw 207 to rotate through the motor 206. The nut seat 208 first slides downwards. After sliding to the bottom of the limit area, the worker pulls the clamping plate 304 outwards. The clamp 304 is opened, creating a gap between the clamping plate 304 and the fixing ring 302. The packaging bag is placed between the clamping plate 304 and the fixing ring 302. The clamping plate 304 is released, and the packaging bag is clamped by the spring's rebound force. Then, the nut seat 208 rises, causing the packaging bag to slide to the bottom of the discharge hopper 2 and cover the discharge hopper 2. At this time, the electric cylinder 101 is activated, pushing out the gripper 103 on the push rod 102, so that the gripper 103 clamps the packaging bag on the discharge hopper 2. As the material discharge hopper 2 rises, the nut seat 208 rises again to the height of the limiting plate 7. Since the fixing ring 302 and the clamping plate 304 elastically clamp the packaging bag, the packaging bag clamped by the claw 103 will tightly wrap around the outer wall of the discharge hopper 2 as the nut seat 208 rises, thus detaching from the fixing ring 302 and the clamping plate 304, and the filling process begins. After the filling is completed, the packaging bag containing zinc oxide material is moved parallel to the next stage through the limited area of ​​the limiting rod 5. Seal the bag, retract the push rod 102, and lower the nut seat 208 to place the fixing ring 302 inside the packaging bag. Pull the clamping plate 304 outward to fix the packaging bag between the fixing ring 302 and the clamping plate 304. Raise the nut seat 208 to move the packaging bag to the bottom of the discharge hopper 2. Push the push rod 102 again to clamp the packaging bag on the discharge hopper 2 with the claw 103. Raise the nut seat 208 to detach the packaging bag from the fixing ring 302 and start loading. Repeat this process to package the zinc oxide material.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
