Description

Technical Field

[0001] The utility model belongs to blanking equipment in the field of machinery, in particular to an auxiliary unpacking and blanking device. Background Art

[0002] The rubber tire production process requires a large amount of powdered raw materials. These raw materials are packaged in square, four-piece bags by the manufacturer and shipped to the tire manufacturing company. The bags are then hoisted by the tire manufacturing company's staff. Each bag has openings at the top and bottom: an inlet for packaging at the manufacturer and an outlet for unpacking at the bottom. To unload the material, the bag is hoisted and moved over the inlet of the feed pipe. The rope securing the opening at the bottom of the bag is then untied to release the powder into the raw material tank. During the unpacking process, the powdered raw materials are prone to bridging within the four-piece bags due to intermolecular forces (van der Waals forces) and their hygroscopic properties. This slows unloading and delays the unpacking process. This requires staff to manually or with a shovel shovel to unclog the bags and shake out the powdered material. This manual process is not only time-consuming and labor-intensive, but also unsafe. Utility Model Content

[0003] In order to solve the time-consuming, labor-intensive and unsafe technical problems caused by manually beating and shaking off powder in the existing tire production unloading process, the utility model provides an auxiliary unpacking and unloading device. The unpacking device automatically beats the material bag mechanically to scatter and shake off the powder, which saves time and effort, and personnel can control the material bag away from the hoisting from the outside, which is safe and convenient.

[0004] The technical solution adopted by the present invention to solve the technical problem is: an auxiliary unpacking and unloading device, including a unloading port for docking a material bag, characterized in that a plurality of vibration plates capable of beating the material bag are provided at the unloading port, the vibration plates are distributed around the unloading port, and each vibration plate is connected to a driving mechanism and can beat the material bag under the drive of the vibration plates. By arranging a plurality of vibration plates around the unloading port, the driving mechanism is used to drive the vibration plates to beat the material bag, and the powder in the material bag that is absorbed by bridging and clustering at the corners of the bag is shaken off, so that the powder falls smoothly into the unloading port, and there is no need to manually beat the material bag to shake off the powder, so that the operator can stand in an area far away from the outer periphery of the material bag to operate, and the safety of unloading is greatly improved.

[0005] As a further improvement and supplement to the above technical solution, the present invention adopts the following technical measures: the drive mechanism is composed of a plurality of independently operating drive units, and each drive unit is matched with a vibration plate. The drive mechanism is composed of multiple independently operating drive units, each drive unit is matched with a vibration plate, and each vibration plate can independently work to beat the material bag, thereby simulating an operator individually beating and shaking the powder inside the material bag at a specific location on the side of the material bag.

[0006] Preferably, the vibration plate is placed obliquely above the discharge port, with the lower end of the vibration plate obliquely inwardly toward one side of the discharge port and rotatably connected to the edge of the discharge port, and the upper end of the vibration plate obliquely outwardly toward the side away from the discharge port and connected to the driving unit. When the driving unit is in operation, the vibration plate is pushed and pulled so that the vibration plate swings back and forth around the rotating connection end to hit the material bag. The upper end of the vibration plate is obliquely connected to the driving unit outwardly, and the lower end is obliquely connected to the edge of the discharge port. When the driving unit is in operation, the driving unit pushes and pulls the vibration plate so that the vibration plate swings back and forth around the rotating connection end connected to the edge of the discharge port, hitting the hanging material bag, so that the powder in the material bag that is bridged or clustered and adsorbed at the peripheral bag corners is shaken off under the vibration of the beating force, falls into the discharge port, and is sent to the feeding pipe.

[0007] Preferably, the vibration plate is an isosceles trapezoidal flat plate, with the longer and shorter sides of the two bases of the isosceles trapezoid serving as the upper and lower ends of the vibration plate, respectively. The vibration plate is an isosceles trapezoidal shape that is wider at the top and narrower at the bottom, with the wider side at the top, which provides a larger contact surface when tapping the material bag, thereby increasing the tapping area and improving the tapping effect.

[0008] Preferably, the drive unit is connected to the middle section of the long side of the isosceles trapezoid, and the vibration plate is rotatably connected to the edge of the discharge port via a rotation axis extending along the short side of the isosceles trapezoid. The drive unit is connected to the vibration plate at the middle section of the long side of the isosceles trapezoid, and the rotational connection between the vibration plate and the base is via the rotation axis extending along the short side of the isosceles trapezoid, so that the vibration plate is stably stressed during operation, swinging back and forth to tap the material bag.

[0009] Preferably, the drive unit comprises a telescopic assembly mounted on the base, the telescopic assembly comprising a main member hinged on the base and a secondary member hinged on the upper end of the vibration plate, the secondary member being movably connected to the main member. During operation, the secondary member moves back and forth relative to the main member, while the main member and secondary member simultaneously move about their respective pivoting connections, thereby pushing and pulling the vibration plate, thereby causing the vibration plate to swing back and forth and strike the material bag.

[0010] Preferably, the base is a frame with a gap in the middle. A tapered tube with a larger top and a smaller bottom is provided in the gap as a feed pipe. The small opening at the bottom of the tapered tube forms a feed opening. The lower end of the vibrating plate is rotatably connected to the inner wall of the tapered tube at the edge of the feed opening. The base adopts a frame structure and can be manufactured by welding channel steel during use. The gap in the middle is used to install the feed pipe. The feed pipe adopts a tapered tube with a larger top and a smaller bottom to facilitate the collection and fall of powder. The lower end of the vibrating plate is rotatably connected to the inner wall of the tapered tube.

[0011] Preferably, the main component and auxiliary component are respectively a piston cylinder and a piston rod. One end of the piston rod is sealed and inserted into the piston cylinder. The end of the piston rod extending out of the piston cylinder is hinged upward to the vibration plate. The end of the piston cylinder away from the piston rod is hinged downward to the base. The piston cylinder drives the piston rod to extend and retract by injecting or discharging a driving medium. The main component and auxiliary component are respectively a piston cylinder and a piston rod. During operation, injecting or discharging a driving medium into the piston cylinder drives the piston rod to extend and retract relative to the cylinder body. The hinged end of the piston rod pushes and pulls the vibration plate to cause it to oscillate.

[0012] Preferably, the piston cylinder is an oil-pressure cylinder and the driving medium is hydraulic oil; or the piston cylinder is a pneumatic cylinder and the driving medium is compressed air. The piston cylinder can be driven by oil pressure or pneumatic pressure, using hydraulic oil or compressed air as the driving medium to cause the piston rod to move telescopically.

[0013] Preferably, the number of the vibration plates is 3 to 4, and they are evenly distributed around the discharge port. The 3 to 4 vibration plates evenly distributed around the discharge port can meet the production needs of beating the material bag to shake out the material. Too few vibration plates will result in excessive driving load for each vibration plate, and too many vibration plates will result in a small beating area and poor shaking effect.

[0014] The beneficial technical effects of the utility model are as follows: a number of vibration plates are arranged around the discharge port, and a driving mechanism is used to drive the vibration plates to beat the material bag, thereby breaking up and shaking out the powder in the material bag that is adsorbed on the peripheral corners due to bridging and clustering. A mechanical device is used to replace the existing operator's manual or tool-based beating, which is not only easy and labor-saving but also safe, and the operator can operate in the peripheral area away from the material bag.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific implementation methods.

[0020] like Figures 1 to 3As shown, the utility model is an auxiliary unpacking and unloading device, including a feeding port 1 for docking a material bag, and 3 to 4 vibration plates 2 for beating the material bag are provided at the feeding port 1. In this embodiment, 4 are preferred, and all the vibration plates 2 are evenly distributed around the feeding port 1. The vibration plates 2 are connected to a driving mechanism and can move under the drive thereof to beat the material bag. The driving mechanism is composed of a number of independently working driving units 3. The number of driving units in this embodiment is the same as that of the vibration plates, which is also 4. The driving units 3 and the vibration plates 2 are matched and connected one by one, and each driving unit 3 drives the paired vibration plate 2 to move and beat the material bag.

[0021] During operation, the drive unit drives the matching vibration plate to beat the material bag, breaking up and shaking out the powder in the bag that is adsorbed on the corners of the bag due to bridging and clustering, so that the powder falls smoothly into the discharge port. The operator does not need to manually beat the material bag to shake off the powder, but only needs to stand in the outer area away from the material bag to control the drive unit, which greatly improves the safety of material discharge.

[0022] Furthermore, as shown in the figure, the vibration plate 2 is placed obliquely above the discharge port 1, the lower end of the vibration plate 2 is inclined inward toward one side of the discharge port 1 and is rotatably connected to the edge of the discharge port 1, and the upper end of the vibration plate 2 is inclined outward toward the side away from the discharge port 1 and is connected to the drive unit 3. When the drive unit 3 is working, by pushing and pulling the vibration plate 2, the vibration plate 2 can be made to swing back and forth around the rotating connection end to hit the material bag.

[0023] Furthermore, the vibration plate 2 in this embodiment is preferably an isosceles trapezoidal flat plate, with the longer of the two bases of the isosceles trapezoid serving as the upper end of the vibration plate 2 and the shorter side serving as the lower end of the vibration plate 2. The drive unit 3 is connected to the vibration plate 2 in the middle of the longer side of the isosceles trapezoid. The vibration plate 2 is rotatably connected to the edge of the feed opening 1 via a rotating shaft extending along the shorter side of the isosceles trapezoid. The isosceles trapezoidal vibration plate, which is wide at the top and narrow at the bottom, has the wider side at the top, which provides a larger contact surface when tapping the material bag, thereby increasing the tapping area and improving the tapping effect.

[0024] Furthermore, the drive unit 3 includes a telescopic assembly mounted on the base 4. The telescopic assembly comprises a main component hinged on the base 4 and a secondary component hinged on the upper end of the vibration plate 2, with the secondary component movably connected to the main component. The base 4 is a frame with a central gap. The frame can be assembled by welding common channel steel. A tapered tube 5, larger at the top and smaller at the bottom, is located in the gap, serving as a feed pipe. The small opening at the bottom of the tapered tube 5 forms the feed port 1. The inner wall of the tapered tube facilitates the collection of powdered material as it falls into the feed port. The lower end of the vibration plate 2 is rotatably connected to the inner wall of the tapered tube 5 at the edge of the feed port 1.

[0025] Furthermore, the main component and auxiliary component are respectively a matching piston cylinder 6 and a piston rod 7. One end of the piston rod 7 is sealed and inserted into the piston cylinder 6. The end of the piston rod 7 extending out of the piston cylinder 6 is hinged upward to the vibration plate 2, and the end of the piston cylinder 6 away from the piston rod 7 is hinged downward to the base 4. The piston cylinder 6 drives the piston rod 7 to extend and retract by injecting or discharging a driving medium. The piston rod pushes and pulls the vibration plate, and the vibration plate swings back and forth around the rotating connection end with the inner wall of the conical tube. During this process, the piston cylinder will also swing around its hinged end connected to the base. In this embodiment, the piston cylinder is preferably a pneumatic cylinder, and the driving medium is compressed air. It has a simple structure, low manufacturing cost, and reliable operation. In addition, the piston cylinder can also be a hydraulic cylinder, and the driving medium in this case is hydraulic oil.
