Description

Technical Field

[0001] This utility model relates to the field of material conveying technology, and in particular to a leak-proof device for a plate feeder. Background Technology

[0002] In today's industrial production and material handling processes, plate feeders play a crucial role, widely used in mining, metallurgy, building materials, chemicals, and many other fields, shouldering the important responsibility of continuously and stably transporting large quantities of bulk materials to subsequent processing stages. However, with the continuous expansion of production scale and increasingly stringent requirements for production efficiency and environmental protection, traditional plate feeders have exposed a series of problems that urgently need to be addressed. On the one hand, during the material feeding stage, since the material usually falls freely into the feeder from a certain height under gravity, the enormous impact force it carries directly acts on the feeder body. Prolonged, high-intensity impacts not only easily cause wear and deformation of structural components near the feeder's inlet, severely affecting the equipment's service life, but also trigger material rebound and splashing, causing material to scatter around the equipment, resulting in material waste, increased on-site cleanup workload, and disruption of normal production order.

[0003] In the prior art, Chinese patent document CN222063131U, concerning a material leakage prevention device for a plate feeder, proposes that by setting a first baffle plate and a second baffle plate, the material can be blocked when it rebounds and collapses during its fall, as well as when it moves with the plate feeder. This reduces the possibility of the material falling from both sides of the plate feeder and ensures that the material moves forward with the plate feeder. However, despite the baffle plates, the material will still collide with the baffle plates during its fall, thus posing a certain risk of falling. Therefore, although this design reduces material leakage to some extent, it still cannot eliminate the hidden danger of material falling. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a material leakage prevention device for plate feeders to solve the problem of material splashing and falling when it collides with the device during the falling process.

[0005] To achieve the above objectives, this utility model provides a leak-proof device for a plate feeder, comprising: a base, wherein a feeder body is mounted on one side of the base;

[0006] A collision avoidance component is installed on one side of the base and is used to reduce the impact of material discharge on the feeder body;

[0007] A splash guard assembly is installed on one side of the feeder body.

[0008] Preferably, the anti-collision component includes a plurality of support columns mounted on one side of the base, a receiving frame movably mounted on the side of the support columns away from the base, a receiving groove is provided in the receiving frame, a plurality of receiving columns are evenly installed in the receiving groove, rollers are rotatably mounted on each receiving column, and a sieve plate is installed in the receiving groove on the side near the support column.

[0009] Preferably, a pressure spring is installed on the side of each of the support columns away from the base, and a snap-fit ​​block is installed on the side of each pressure spring away from the support column.

[0010] Preferably, a plurality of snap-fit ​​posts are fixedly installed on both sides of the receiving frame, and the plurality of snap-fit ​​posts are adapted to the snap-fit ​​block.

[0011] Preferably, a buffer groove is provided in the receiving groove, a screen plate is movably installed in the buffer groove, a plurality of return springs are evenly installed on both sides of the screen plate near the support column, the other side of the plurality of return springs is fixedly installed on one side of the buffer groove, and a plurality of material leakage holes are evenly provided on the screen plate.

[0012] Preferably, the splash-proof component includes a plurality of limiting posts installed on one side of the base, the plurality of limiting posts being evenly installed on both sides of the feeder body, and a splash-proof frame being installed on the side of the plurality of limiting posts away from the base.

[0013] Preferably, a plurality of connecting plates are evenly installed on both sides of the splash-proof frame, and a second limiting plate is installed on the side of the plurality of connecting plates near the base. First limiting plates are symmetrically installed on both sides of the second limiting plate, and a dustproof plate is installed on the side of the splash-proof frame away from the base.

[0014] Preferably, the second limiting plate is adapted to the limiting post, and the two first limiting plates abut against the sides of the two outermost limiting posts.

[0015] The beneficial effects of this utility model are:

[0016] 1. This type of plate feeder's anti-leakage device, through the installation of anti-collision components, ensures that when material first impacts the rollers in the receiving groove within the receiving frame, the impact force from the falling material causes these rollers to rapidly rotate around the receiving column. During this rotation, the material's initial vertical downward kinetic energy is decomposed, with a portion of it converted into rotational energy. This effectively dissipates some of the impact force, preventing the material from scattering due to violent collisions with the device and avoiding it falling out of the device—serving as the first layer of buffering. When the material impacts... When the material falls into the sieve, the sieve moves towards the support column under force. This movement compresses the return spring, which has its own elastic force to restore its original shape. This elastic force acts in the opposite direction on the sieve, thus relieving part of the impact force carried by the material, which is regarded as a second layer of buffer. The entire receiving frame is elastically connected by pressure springs installed on the side of the support column away from the base. When the material falls into the receiving frame, the receiving frame is pressed down by force, and the pressure spring is compressed. Due to the elasticity of the spring itself, the receiving frame will generate an upward buffering force on the input material. This works in conjunction with the buffering effect of the roller and the return spring to ensure that most of the impact force of the material is relieved.

[0017] 2. This type of plate feeder anti-leakage device, by setting up anti-splash components, allows material to fall into the feeder body. Limiting posts are evenly installed on both sides of the feeder body, and anti-splash frames are installed on the side of the limiting posts away from the base, forming an enclosed space that effectively restricts the movement direction of the material. Connecting plates are also evenly installed on both sides of the anti-splash frame. A second limiting plate is installed on the side of the connecting plates closest to the base. The second limiting plate is adapted to the limiting posts, while the two first limiting plates abut against the sides of the two outermost limiting posts, further enhancing the stability of the enclosed space. The dustproof plate effectively blocks some of the dust generated during material transportation, reducing the spread of dust in the air. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0028] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0029] like Figures 1 to 6 As shown, the anti-leakage device for the plate feeder includes: a base 1, on one side of which the feeder body 18 is installed; an anti-collision component, which is installed on one side of the base 1 and is used to reduce the impact of material feeding on the feeder body 18; and an anti-splash component, which is installed on one side of the feeder body 18.

[0030] At the start of material conveying, the operator drops the material to be conveyed from the top of the anti-collision component. The material begins to fall under its own weight. When the material impacts the first layer of buffer structure, some of the material's kinetic energy is quickly absorbed and converted. The remaining energy causes the material to change its direction of movement and continue to slide downwards. Through the sequential action of multiple layers of buffer structure, the huge impact force originally carried by the material due to falling from a height is gradually reduced, allowing it to smoothly enter the feed inlet area set in the feeder body 18 in a relatively stable and gentle state. When the conveying components inside the feeder body 18 drive the material to move quickly along the predetermined route, the material will inevitably tend to splash upwards or outwards due to factors such as vibration and inertia. At this time, the anti-splash component can prevent the material from accidentally falling out of the feeder body 18, ensuring that the entire feeding process proceeds in an orderly manner with high efficiency, stability and zero material leakage.

[0031] like Figure 2 , Figure 3 , Figure 4 As shown, the anti-collision component includes several support columns 2 on one side of the mounting base 1. A receiving frame 5 is movably installed on the side of the support column 2 away from the base 1. A receiving groove 7 is opened in the receiving frame 5. Several receiving columns 19 are evenly installed in the receiving groove 7. Rollers 9 are rotatably installed on each of the receiving columns 19. A screen plate 8 is installed in the receiving groove 7 near the support column 2. A pressure spring 3 is installed on the side of the support column 2 away from the base 1. A locking block 4 is installed on the side of the pressure spring 3 away from the support column 2. Several locking columns 6 are fixedly installed on both sides of the receiving frame 5. The locking columns 6 are adapted to the locking blocks 4. A buffer groove 10 is opened in the receiving groove 7. A screen plate 8 is movably installed in the buffer groove 10. Several return springs 11 are evenly installed on both sides of the screen plate 8 near the support column 2. The other side of the return springs 11 is fixedly installed on one side of the buffer groove 10. Several leakage holes 12 are evenly opened on the screen plate 8.

[0032] The material to be conveyed is placed on top of the anti-collision assembly. The material then accelerates downwards under its own weight. When the material first impacts the rollers 9 in the receiving groove 7 within the receiving frame 5, the impact force caused by the falling material causes these rollers 9 to quickly rotate around the receiving column 19, as the rollers 9 are evenly distributed within the receiving groove 7 and rotatably mounted via the receiving column 19. During the rolling process of the rollers 9, the enormous kinetic energy of the material initially moving vertically downwards is decomposed, with a portion of the kinetic energy being converted into the rotational energy of the rollers 9. This effectively dissipates some of the impact force generated by the falling material, preventing it from being damaged by the impact with the receiving frame 5. The material collides violently and scatters in all directions, preventing it from falling out of the device. Simultaneously, some material does not directly contact the roller 9 but falls directly into the receiving groove 7 onto the screen plate 8 installed near the support column 2. Material that initially contacts the roller 9 and is partially depressed by it will subsequently fall onto the screen plate 8 under gravity. At this point, several return springs 11 evenly installed on both sides of the screen plate 8 near the support column 2 begin to function. When material impacts the screen plate 8, the screen plate 8 is forced to move towards the support column 2. This movement compresses the return springs 11. The spring itself has a restoring force, which acts in the opposite direction on the screen plate 8, thus dissipating part of the impact force carried by the material. In addition, due to the impact of the falling material, some fragments are inevitably generated. These fragments can fall smoothly into the bottom of the receiving trough 7 through the discharge hole 12. Furthermore, the entire receiving frame 5 is elastically connected by several pressure springs 3 installed on the side of the support column 2 away from the base 1. When the material falls into the receiving frame 5, the receiving frame 5 is pressed down, and the pressure springs 3 are compressed. Due to the elasticity of the spring itself, the receiving frame 5 will provide an upward buffer against the input material. The force, combined with the buffering effect of the roller 9 and the return spring 11, ensures that most of the impact force of the material is removed. Finally, the material, which has been buffered layer by layer and whose impact force has been greatly weakened, can enter the feed port area of ​​the feeder body 18 protected by the splash-proof component from the lower outlet of the receiving frame 5 in a relatively stable and gentle state. This effectively prevents the material from leaking or scattering due to the impact force generated during the initial fall during the subsequent conveying process of the feeder body 18, and ensures that the entire feeding process can be carried out in an orderly and continuous manner with high efficiency, stability and zero material leakage.

[0033] like Figure 5 , Figure 6As shown, the splash guard assembly includes several limiting posts 20 installed on one side of the base 1. The limiting posts 20 are evenly installed on both sides of the feeder body 18. A splash guard frame 13 is installed on the side of the limiting posts 20 away from the base 1. Several connecting plates 15 are evenly installed on both sides of the splash guard frame 13. A second limiting plate 17 is installed on the side of the connecting plates 15 close to the base 1. First limiting plates 16 are symmetrically installed on both sides of the second limiting plate 17. A dustproof plate 14 is installed on the side of the splash guard frame 13 away from the base 1. The second limiting plate 17 is adapted to the limiting posts 20. The two first limiting plates 16 abut against the sides of the two outermost limiting posts 20.

[0034] After being processed by the anti-collision component, the material enters the area defined by the splash guard component in a relatively stable and almost impact-free state. The material then falls into the feeder body 18. At this time, the conveying components inside the feeder body 18 operate efficiently according to a preset stable speed and predetermined route, steadily carrying and driving the material forward. The splash guard component then comes into play. By evenly installing limiting posts 20 on both sides of the feeder body 18 and installing a splash guard frame 13 on the side of the limiting posts 20 away from the base 1, an enclosed space is formed. The splash guard 13 effectively restricts the movement direction of the material. Connecting plates 15 are also evenly installed on both sides of the splash guard 13. The connecting plates 15 are connected to the side of the base 1 and a second limiting plate 17 is installed. The second limiting plate 17 is adapted to the limiting post 20. The two first limiting plates 16 abut against the sides of the two outermost limiting posts 20, which further enhances the stability of the enclosed space. At the same time, a dustproof plate 14 is installed on the side of the splash guard 13 away from the base 1, which effectively blocks some of the dust generated during the transportation of the material and reduces the spread of dust in the air.
