Description

Technical Field

[0001] The invention relates to the technical field of zinc oxide packaging equipment, and in particular discloses automatic grading and packaging equipment for a zinc oxide production line. Background Art

[0002] Zinc oxide is a commonly used chemical additive, which is widely used in the production of products such as plastics, silicate products, synthetic rubber, lubricants, paints and coatings, ointments, adhesives and flame retardants. In the actual production process, in order to facilitate transportation and storage, the produced zinc oxide powder is usually quantitatively packaged and sealed using zinc oxide grading and packaging equipment. The existing zinc oxide grading and packaging equipment requires workers to manually fix the woven bags under the hopper during the zinc oxide packaging process. The degree of automation of the equipment needs to be improved. After the packaging is completed, the workers manually assist in sealing. Repeatedly taking and placing the woven bags can easily cause worker fatigue. The workers' working status can easily affect the efficiency and quality of the zinc oxide powder packaging and sealing, and is not conducive to saving labor costs and is relatively inconvenient. Therefore, in order to solve the above problems, the present invention proposes an automated grading and packaging equipment for a zinc oxide production line. Summary of the Invention

The above design facilitates controlling the opening and closing of the two solenoid valves according to actual packaging requirements, thereby achieving precise feeding and leakage.

[0007] As a further configuration of the above solution, a control box is provided on one side of the storage mechanism. The above design facilitates setting the operating procedures of relevant components to control the operation of relevant components in the equipment.

[0008] As a further arrangement of the above scheme, a long hole and an arc-shaped hole are respectively provided on both sides above the second bracket, a first cylinder is provided above the second bracket, a mounting block and an electric suction cup are respectively provided at both ends of the first cylinder, a woven bag is provided on the side of the electric suction cup away from the first cylinder, a connecting shaft is provided running through the interior of the mounting block, a gear is provided at the end of the connecting shaft away from the arc-shaped hole, and the end of the connecting shaft away from the gear is connected to the second bracket, a support block is provided on the outside of the first cylinder, a limiting shaft is provided on one side of the support block, the limiting shaft passes through the interior of the arc-shaped hole, and a rack is provided below the gear. The above design can keep the above components stable during operation, which is convenient for automatic suction of woven bags.

[0009] As a further arrangement of the above scheme, the teeth of the gear are meshed with the teeth of the rack, and a protrusion is provided at the lower end of the rack, which is connected to the long strip hole, one end of the rack is connected to a second cylinder, a protective cover is provided above the rack, a third bracket is provided on one side of the second bracket, a third cylinder is provided at the upper end of the third bracket, an electric suction cup is provided at the telescopic end of the third cylinder, a placement rack is provided at the lower end of the second bracket, a baffle is connected to the end of the placement rack away from the third bracket, and a woven bag is placed inside the placement rack. The above design makes it convenient for workers to place multiple woven bags on the placement rack at one time, and can suck the woven bags placed inside the placement rack by adjusting the angles of the first cylinder and the electric suction cup to be perpendicular to the ground. After the suction is completed, the woven bag is placed under the second discharge pipe through the operation of the second cylinder and another electric suction cup is used to open the woven bag to fill zinc oxide powder, saving manpower.

[0010] As a further arrangement of the above scheme, a fourth cylinder is provided at the upper end of the fourth bracket, a roller frame is provided at the top end of the fourth bracket, a plurality of rollers are provided on both sides below the roller frame, and the telescopic end of the fourth cylinder is connected to the fourth bracket. The above design facilitates further fitting of the inner side of the bag opening of zinc oxide after the zinc oxide filling is completed, thereby avoiding wrinkles on the bag opening and providing convenience for the sealing machine to seal.

[0011] The two solenoid valves involved in the automatic grading and packaging equipment of the zinc oxide production line are all servo solenoid valves, and the four cylinders involved are all servo cylinders. During use, a sufficient amount of zinc oxide powder is placed in the first storage hopper, and a sufficient amount of woven bags are placed on the inside of the placement rack. The weighing value of the weighing sensor is set on the control box and the weighing sensor is connected to the first solenoid valve. The first solenoid valve is opened, and an appropriate amount of zinc oxide powder is injected into the second storage hopper through the first discharge pipe. When the set value of the weighing sensor is reached, the first solenoid valve is automatically closed. The control box is used to control the contraction of the second cylinder to form a transmission between the rack, gear, first cylinder and electric suction cup. The angle of the first cylinder and the electric suction cup is adjusted to be perpendicular to the placement rack. At this time, the limit shaft is located at the lower end of the arc hole. Then start the first cylinder and the electric suction cup, adjust the vertical position of the electric suction cup, and make the electric suction cup suck the woven bag. After the sucking is completed, control the second cylinder to extend and reset the limit shaft to the upper end of the arc hole, so that the first cylinder is parallel to the ground. At this time, the woven bag is perpendicular to the ground and the bag opening is located in the middle of the lower part of the second discharge pipe. The control box is used to control the third cylinder and another electric suction cup, so that the electric suction cup absorbs the other side of the woven bag. Then, the first cylinder and the third cylinder are controlled to retract a certain distance at the same time to expand the woven bag. The second solenoid valve is opened to pour the zinc oxide powder in the second storage hopper into the woven bag. After filling, the second solenoid valve is closed and the first solenoid valve is opened. An appropriate amount of zinc oxide powder is poured into the second storage hopper again. The control box is used to control the first cylinder and the third cylinder to extend toward each other so that the two sides of the bag opening are fitted together. The fourth cylinder is controlled to extend to move the roller frame and the roller toward the woven bag so that the bag opening is located between the rollers on both sides. Then, the two electric suction cups are closed at the same time, causing the woven bag to fall onto the transmission belt. Under the transmission action of the electric conveyor belt, the bag opening of the woven bag passes through the closing auxiliary mechanism and the sealing machine in sequence for automatic sealing. The sealed woven bag containing zinc oxide powder can be stored and transported.

[0012] The present invention has the following beneficial effects during practical application:

[0013] The bag-holding mechanism in the device can automatically clamp and hold open the woven bags, thereby improving the degree of automation of the grading packaging equipment, improving the efficiency of zinc oxide packaging, ensuring the packaging quality, and saving labor costs. The design of the long holes and arc holes in the bag-holding mechanism can further limit the position of the rack and the first cylinder, ensuring that the first cylinder and the electric suction cup accurately absorb and hold open the woven bags.

[0014] The closing auxiliary mechanism can position the bag opening of the woven bag before it passes through the sealing machine, so that the two sides of the inner wall of the bag opening of the woven bag are initially fitted and kept flat, providing convenience for smooth sealing while further saving manpower and improving the degree of automation of the equipment.

[0015] The combined design of the placement rack and the baffle arranged on the inner side of the lower end of the second bracket makes it easy to place a sufficient number of woven bags on the inner side of the placement rack at one time, which is convenient for the electric suction cup to suck and can effectively save space.
