Abstract
The utility model discloses a compressing apparatus of discharge hole of feeding device, which comprises a valve box (1) connected with a discharge hole, a cylinder (2) is arranged on the valve box, a piston rod (3) of the cylinder is connected with a pressure plate (4), the pressure plate is opposite to a discharge hole (5), and a spring (6) is arranged between the pressure plate and the valve box. Since the spring is arranged between the pressure plate and the valve box, the pressure of the spring is enough to lead the pressure plate to have enough pressure and contact with the discharge hole under the condition of losing pressure of air pressure, thereby forming non-powered compression. In addition, a seal ring is arranged on the pressure plate, the sealing property between the discharge hole and the pressure plate is improved, and therefore, the leakage problem of the discharge hole can be effectively avoided when closing. The compressing apparatus of discharge hole of feeding device solves the phenomenon that a crown block feeding device leaks materials under the condition that air supply in a workshop is not enough originally. The compressing apparatus of discharge hole of feeding device can be widened and applied in similar production flows and industries which need non-powered compression, and has simple structure and strong practicability.
Description
Technical field
The utility model relates to a kind of hold-down gear, particularly a kind of hold-down gear of feeding device discharge port.
Background technology
Be used in potroom and give the discharge port of the overhead traveling crane feeding device that the electrolyzer blanking uses, open or close by pressing plate of an air cylinder driven.When needing blanking, the withdrawal of the piston rod of institute's cylinder drives pressing plate and leaves discharge port, and the material in the hopper flows into electrolyzer under wind-force or deadweight effect; When not needing blanking, the piston rod of cylinder stretches out, and promotes pressing plate and is pressed on the discharge port, makes pressing plate contact and be adjacent to discharge port, will block from the material that air-driven chute comes, and does not allow material flow out.In fact pressing plate is the effect of playing a switch.
But in use have some problems, can cause the problem that fits badly, its reason one is because the air feed air pressure instability of cylinder, and insufficient pressure causes sealing bad sometimes; Another reason is that the face contact seal itself between pressing plate and the discharge port is just bad.So discharge port can generation in various degree leak material when the overhead traveling crane feeding device stops to move.
The utility model content
The purpose of this utility model is, a kind of hold-down gear of feeding device discharge port is provided, and to improve the stopping property of discharge port, prevents to reveal when air pressure is not enough.
The technical solution of the utility model: a kind of hold-down gear of feeding device discharge port, comprise the clack box that is connected with discharge port, clack box is provided with cylinder, and the piston rod of cylinder is connected with pressing plate, and pressing plate is relative with discharge port; Between pressing plate and clack box, be provided with spring.
In the hold-down gear of above-mentioned feeding device discharge port, described both ends of the spring is provided with spring support.
In the hold-down gear of aforesaid feeding device discharge port, described pressing plate is provided with sealing-ring.
Compared with prior art, the utility model is owing to be provided with spring between pressing plate and clack box, and the pressure of spring can form unpowered compressing with losing under the situation of atmospheric pressure and can having enough pressure to contact with discharge port by pressing plate completely.On pressing plate, be provided with sealing-ring in addition, improved the stopping property between discharge port and the pressing plate, so effectively avoided the leakage problem of discharge port when closing.Solved and under the insufficient situation of workshop air feed, caused the overhead traveling crane feeding device to leak the phenomenon of material originally.The utility model can expand be applied to need of the same type carry out unpowered compress other Production Flow Chart and industry in, it is simple in structure, practical.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Being labeled as in the accompanying drawing: 1-clack box, 2-cylinder, 3-piston rod, 4-pressing plate, 5-discharge port, 6-spring, 7-spring support, 8-sealing-ring.
Embodiment
Be described in further detail below in conjunction with the hold-down gear of drawings and Examples a kind of feeding device discharge port of the present utility model, but not as the foundation of the utility model being done any restriction.
Embodiment.The hold-down gear of a kind of feeding device discharge port of the present utility model, as shown in Figure 1.Comprise the clack box 1 that is connected with discharge port, clack box 1 is provided with cylinder 2 (also can adopt hydro-cylinder), and the piston rod 3 of cylinder 2 is connected with pressing plate 4, and pressing plate 4 is provided with sealing-ring 8; Sealing-ring 8 contacts with the port of discharge port 5, and sealing-ring 8 employing elasticity material are preferably made.Pressing plate 4 is relative with discharge port 5; Between pressing plate 4 and clack box 1, be provided with spring 6.It is the spring 6 that axis has sufficient intensity and can be driven by cylinder 2 with the bar of cylinder 2 footpath medullary ray that spring 6 is one, and spring 6 two ends are provided with spring support 7.Spring 6 is stuck on the spring support 7 at two ends.
Claims (3)
1. the hold-down gear of a feeding device discharge port, it is characterized in that: comprise the clack box (1) that is connected with discharge port, clack box (1) is provided with cylinder (2), and the piston rod (3) of cylinder (2) is connected with pressing plate (4), and pressing plate (4) is relative with discharge port (5); Between pressing plate (4) and clack box (1), be provided with spring (6).
