Description

An environment-friendly PVC dust-proof blanking device

technical field

The utility model belongs to the technical field of hoppers and environmental protection, in particular to a cutting device for sheet materials, in particular to an environment-friendly PVC dust-proof cutting device.

Background technique

At present, in the production process that needs to use the hopper to discharge the material, because the hopper itself is tapered, the size of the inlet end is large, and the size of the outlet end is small, the material in the hopper will appear in the process of flowing out of the hopper from the outlet end. The phenomenon of material bridging occurs due to mutual extrusion, that is, the materials are stuck in the hopper due to mutual extrusion and cannot flow out smoothly, resulting in uneven feeding of the hopper, and even the illusion of material breakage.

For flake materials, such as PVC flake materials, due to the mutual extrusion in the hopper, the friction between each other is relatively large. Compared with granular materials, flake materials are more likely to fall during the process of feeding through the hopper. Material bridging phenomenon, therefore, can easily lead to uneven feeding of the hopper, and even the false phenomenon of material breaking, which seriously affects the production efficiency of feeding. Although some auxiliary blanking equipment has also appeared on the market to solve these problems, these auxiliary blanking equipment are either high in use cost, large in energy consumption, poor in economy, inconvenient to operate, or unsatisfactory in blanking effect.

In addition, the material fed by the hopper is generally a granular material with a small particle size. During the use of the existing hopper feeding device, there is no covering material on the top, which easily causes the material dust to splash, causing pollution to the production environment. Affect the health of production operators.

Detailed ways

In order to make the purpose, technical solution and advantages of the utility model clearer, an environment-friendly PVC dust-proof cutting device of the utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

Fig. 1 is a structural schematic diagram of an environment-friendly PVC dust-proof blanking device of the present invention. As shown in Figure 1, according to an exemplary embodiment of the present utility model, the environmentally friendly PVC dust-proof blanking device includes an air inlet pipe 1 and a distribution cylinder 2, wherein the distribution cylinder 2 is an inverted funnel-shaped cylinder, The air intake pipe 1 runs through the sub-material cylinder 2 and is fixedly connected with the smaller end of the sub-material cylinder 2 by welding, and several exhaust through holes 3 are provided on the side wall of the air intake pipe.

According to the utility model, the material distribution cylinder 2 is an inverted funnel-shaped cylinder body, which is used to isolate part of the PVC material 14, and the PVC distributes the material 14 to the surroundings evenly, so that a conical space is formed inside the PVC material 14 to slow down the flow of the hopper. 13 The accumulation of materials at the outlet end prevents uneven feeding and broken materials due to mutual extrusion of materials. The distribution cylinder 2 can also be a cone-shaped cylinder, or a cylinder with other shapes, the present invention is not limited thereto, as long as the circumferential shunting effect of the PVC material 14 can be realized.

The opening at the top of the air intake pipe 1 is the only channel for air intake. During the feeding process of the hopper, compressed air is continuously fed into the opening at the top of the air intake pipe 1. The compressed air flows along the inner cavity of the air intake pipe 1. The PVC material 14 shunted by the barrel 2 is pushed by the gas discharged from the exhaust through hole 3, and falls directly to the bottom of the hopper 13 in a diffusion trend, and falls onto the conveying device 15 through the discharge port of the hopper 13, thereby avoiding A large amount of PVC material 14 concentrates and piles up around the air inlet pipe 1, which causes the discharge port of the hopper 13 to be blocked, and the phenomenon of blanking and bridging occurs. The lower end of the air inlet pipe 1 of the feeder reaches the discharge port of the hopper 13, and is higher than the conveying device 15 below the hopper 13. This design is more conducive to dispersing the material 14 located at the bottom of the hopper 13, and prevents the material 14 from being damaged by the conveying device 15 during transportation. The feeder intake pipe is damaged.

In order to make the PVC material 14 shunted by the material distribution cylinder 2 receive a relatively uniform gas thrust discharged from the exhaust through hole 3, the exhaust through holes 3 should be evenly distributed in the area below the larger end of the material distribution cylinder 2. On the side wall of the intake pipe 1, that is, the distances between two adjacent rows of exhaust through holes 3 are the same, and the diameters of the exhaust through holes 3 are also the same, as shown in Fig. 1 and Fig. 2 . It can not only ensure that the distribution and falling of the PVC material 14 are more uniform, but also reduce the processing cost of the feeder.

During the feeding process of the hopper, in order to increase the thrust of the gas discharged from the exhaust through hole 3 on the PVC material 14, the end of the intake pipe 1 located below the larger end of the material distribution cylinder 2 can be rolled into a pointed cone, and the The opening is welded and sealed, so that all the compressed air entering the inner cavity of the intake pipe 1 is discharged from the exhaust through hole 3, increasing the pressure of the discharged gas, and avoiding the accumulation of PVC material 14 around the intake pipe 1 to cause blanking bridging.

When blanking, due to the inevitable friction between the PVC material 14 and the intake pipe 1 and the distribution cylinder 2, in order to avoid the intake pipe 1 and the distribution cylinder 2 from wearing too fast and to improve their service life as much as possible, the intake pipe 1 Metal straight tubes can be used, and the distribution cylinder 2 can also be correspondingly made of metal cylinders, such as aluminum products and stainless steel products, and the air inlet pipe 1 and the smaller end of the distribution cylinder 2 are fixed by seamless welding. This not only helps to improve the service life of the feeder, but also has a simple structure, convenient manufacture and low implementation cost.

During the feeding process, due to the action of the compressed air in the intake pipe 1, the PVC material 14 will be blown out from the hopper and pollute the environment. A hopper cover 4 matching the size of the hopper is added above the hopper 13 to prevent the feeding process. The medium dust is blown out, reducing the impact on the operating environment. The hopper cover is located above the material distribution cylinder 2, and the air inlet pipe 1 runs through the hopper cover 4, and is seamlessly welded and fixed with the hopper cover 4 perpendicular to each other. At the same time, an arc-shaped feeding flap 5 is set on the hopper cover 4. When feeding is required, the hopper cover feeding flap 5 is opened for feeding. After the feeding is completed, the feeding flap 5 can be directly closed. Simple, save time and labor costs, improve the efficiency of operators.

In order to better fix the hopper 13 and the hopper cover 4 during use, an upper lock 6 is provided on the hopper cover 4, a lower lock 12 is provided on the hopper 13, and the upper lock 6 and the lower lock 12 Corresponding to the position of the hopper, buckle during use to prevent the displacement of the hopper 13 or the hopper cover 13, and better achieve the purpose of dust prevention. Simultaneously, the inner side of the hopper cover 4 is also glued with a full layer of silica gel pads, which are used to absorb the PVC material 14 and further prevent it from being blown out.

The hopper 13 is fed with compressed air during use, so that the air pressure in the hopper 13 is greater than the outside air pressure. In order to achieve the balance of internal and external air pressure, and at the same time to over-purify the air containing dust in the hopper 13, a filter water tank 8 is set to filter the air in the hopper 13, and through the decompression dust discharge pipe 7 to realize the air to filter water Cylinder 8 connections. Filtered water 9 and dust filter screen 10 are arranged in described filtered water tank 8, and dust filter screen 10 is higher than the water level of filtered water 9, and the top of dust filter screen 10 is also provided with exhaust pipe 11, is used for getting rid of through filtering and purifying. Air. The exhaust pipe mouth of decompression dust exhaust pipe 7 should be lower than the water level height of filtered water 9, so that air is all passed into the band filtered water to filter. The air containing dust enters the filtered water 9 through the decompression dust discharge pipe 7 under decompression, removes the water-soluble substances in the air, and then passes through the dust filter 10 to remove the remaining dust. It can be one or more layers, which should be set according to actual production experience, and finally the filtered air is discharged through the exhaust pipe 11. The air dust that has been filtered and purified has been removed, which will not pollute the air and affect the health of operators.

The conveying device 15 described in the utility model can be a screw conveying device or a belt conveying device, but the utility model is not limited thereto, and a simpler or more responsible conveying device can also be used, as long as the conveying effect can be realized. The function of the conveying device 15 is to transport the received material away from the hopper 13 in time, so as to avoid the clogging of the discharge port of the hopper 13 caused by excessive accumulation of material, and ensure the continuous feeding of the hopper 13 . In this way, it can effectively prevent the material 14 in the hopper 13 from cutting and bridging, avoiding the reduction of the amount of material discharged by the hopper 13 per unit time, and even the false phenomenon of material breaking. There is still material in stock, but the phenomenon that it cannot flow out of the hopper 13 smoothly.

The usage method of an environment-friendly PVC dust-proof blanking device of the present invention will be described in detail below.
