Description

Technical Field

[0001] This utility model relates to the technical field of packing strap production equipment, specifically to a transition hopper for packing strap production with a dustproof device. Background Technology

[0002] Currently, in the production process of plastic strapping, the raw materials in the raw material drum first enter the transition hopper at the top of the extruder through the outlet conveyor channel. The raw materials in the hopper are then heated by air before being extruded into shape. However, because the extruder uses air heating during the heating process, the air flows upward from the bottom of the hopper, causing lighter particles and dust to be emitted from the top exhaust port, thus impacting the production environment. Although a collection bag can be connected to the exhaust port via a hose to collect the emitted materials and dust, this still easily leads to an increase in indoor temperature and dust leakage. Furthermore, secondary floating of dust is prone to occur during subsequent dust treatment. Therefore, a mechanism for filtering and cleaning the material discharged from the top outlet of the transition hopper is needed. Summary of the Invention

[0003] In order to solve one or more technical problems existing in the prior art, one of the objectives of this application is to provide an over-load hopper for the production of packing straps with a dustproof device, which can solve the problem of environmental pollution caused by some materials and dust in the top of the hopper being discharged through the top exhaust port due to gas heating, and can also avoid the rapid rise in ambient temperature.

[0004] To solve the aforementioned technical problems, this application adopts the following technical solution:

[0005] A transition hopper for producing packing straps with a dustproof device includes an extruder, a transition hopper located on top of the extruder, an inlet and an outlet located on top of the transition hopper, a collection box, a dust removal mechanism located inside the collection box, and a dustproof hose located between the collection box and the outlet. Dust particles drifting out of the transition hopper enter the collection box through the dustproof hose, and gas is discharged through the collection box. Dust particles entering the collection box are filtered and collected by the dust removal mechanism.

[0006] Preferably, the dust extraction mechanism includes water in the collection box and a mesh plate for scooping dust particles floating on the water surface. Dust injected into the collection box through the dustproof hose is adsorbed and filtered by the water, and dust particles floating on the surface of the water are scooped out by the mesh plate.

[0007] Preferably, the collection box includes a box body, a feed hole, an air outlet and a top cover provided on the top of the box body, and one end of the dustproof hose is connected to the feed hole.

[0008] Preferably, it also includes a movable base with casters, the collection box is placed on the movable base, and the movable base is provided with a metal guardrail to limit the movement of the collection box.

[0009] Preferably, the bottom side of the box is provided with a drain outlet with a valve.

[0010] Preferably, the container is a rectangular plastic bucket, and the length, width and height of the plastic bucket are all not less than 80cm.

[0011] Preferably, the mesh panel includes a handle and a filter screen, one end of the handle is provided with a hook, and the mesh panel is suspended on the metal railing by the hook.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] The air flowing from the bottom mesh within the feed hopper, after being discharged, is separated from dust particles via a combination of dustproof hoses and a collection box. This effectively solves the problem of material in the top feed hopper of existing extruders being discharged through the exhaust port during the upward flow of heated air, thus impacting the production environment. This results in a better production environment, preventing environmental pollution and eliminating the problem of secondary dust re-floating during subsequent processing. Simultaneously, the water in the collection box absorbs heat and cools the gas, effectively controlling its temperature and preventing excessively high ambient temperatures after the gas is released into the air.

[0017] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0018] In the description of this application, it should be understood that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0019] The terms "first," "second," etc., used in this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class, without limiting the number of objects; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0020] like Figure 1 and Figure 2 As shown, a transition hopper for producing packing straps with a dustproof device includes an extruder 1, a transition hopper 2 located on top of the extruder 1, an inlet 3 and an outlet 4 located on top of the transition hopper 2, a collection box 6, a dust removal mechanism 7 located inside the collection box 6, and a dustproof hose 5 located between the collection box 6 and the outlet 4. Dust particles floating out of the transition hopper 2 enter the collection box 6 through the dustproof hose 5, and the gas is discharged through the collection box 6. The dust particles entering the collection box 6 are filtered and collected by the dust removal mechanism 7.

[0021] During the production process of plastic strapping, after the material enters the transition hopper 2 on the extruder 1 through the pipe, the material is heated by air and flows downward into the extruder 1 for melting and discharge. During the discharge process, the heated air flowing upward is discharged outward through the exhaust port 4 at the top and injected into the collection box 6 along the dustproof hose 5. The dust separation mechanism 7 in the collection box 6 separates the dust particles in the discharged hot air from the gas. The gas after dust separation is discharged outward through the collection box 6, while the separated dust particles are filtered and collected by the dust separation mechanism 7 and can be centrally processed. This effectively solves the problem of the material in the top hopper of the existing extruder 1 being discharged outward through the exhaust port 4 during the upward flow of heated air, which affects the production environment. This makes the production process more environmentally friendly and prevents environmental pollution. It also prevents the secondary floating of dust during the later processing.

[0022] A further improvement is made to the dust extraction mechanism 7, which includes water 72 disposed in the collection box 6 and a mesh plate 71 for scooping up dust particles floating on the surface of the water 72. Dust injected into the collection box 6 through the dustproof hose 5 is adsorbed and filtered by the water 72, and dust particles floating on the surface of the water 72 are scooped out by the mesh plate 71.

[0023] The dust extraction mechanism 7 uses a combination of water 72 and a mesh plate 71. Water 72 is injected into the collection box 6. When gas carrying dust particles is injected into the collection box 6, the gas first impacts the surface of the water 72. The water 72 effectively extracts the dust particles around the gas through adsorption, causing them to adhere to the surface of the water 72. The gas, after being filtered by the water 72, rebounds and is then discharged. This effectively controls the dust content in the discharged gas. In particular, the water 72 surface is approximately 30-45 cm away from the top of the box 64. When the gas impacts the water 72, it provides a buffer flow space and sufficient contact area with the water 72 surface. The water 72 also absorbs heat and cools the gas, effectively controlling its temperature and preventing excessively high temperatures from affecting the ambient temperature after the gas is released into the air. The mesh plate 71 quickly and efficiently collects and removes dust particles floating on the water 72 surface, preventing them from scattering and effectively avoiding secondary dust pollution.

[0024] A further improvement is made to the following: the collection box 6 includes a box body 64, a feed hole 61, an air outlet 62 and a top cover 63 located on the top of the box body 64, and one end of the dustproof hose 5 is connected to the feed hole 61; a drain outlet 72 65 with a valve is provided on the bottom side of the box body 64; the box body 64 is a rectangular plastic bucket, and the length, width and height of the plastic bucket are not less than 80cm.

[0025] The collection box 6 consists of a box body 64, a feed port 61, an exhaust port 62, a top cover 63, and a drain outlet 72 65 with a valve. One end of the dustproof hose 5 is connected to the feed port 61, while the gas inside the box body 64 is discharged outward through the exhaust port 62. When the gas enters, it first blows downward through the feed port 61 at the top. The dust-laden gas first impacts the water surface 72, and after contacting the water surface 72, it bounces back into the space at the top of the box body 64 for large-area contact with the water surface 72 for cooling. At the same time, some of the gas is discharged outward through the guide and exhaust port 62. The overall structure is simple, low-cost, and has low requirements for the quality of the water 72. When the water 72 needs to be replaced, the valve can be opened to drain the water 72, making water 72 replacement simple and convenient. The box body 64 is a rectangular plastic bucket with a length, width, and height of not less than 80cm, which provides a large surface area and good effect during precipitation and cooling. When it is necessary to retrieve floating objects, simply open the top cover 63 to operate.

[0026] A further improvement includes a movable base 9 with casters, on which the collection box 6 is placed, and the movable base 9 is provided with a metal guardrail 8 to limit the movement of the collection box 6.

[0027] To facilitate the movement of the container 64 containing water 72, a movable base 9 with casters is installed at the bottom of the container 64. A quadrilateral metal guardrail 8 is formed on the movable base 9 to limit the side of the collection box 6. The metal guardrail 8 can effectively prevent the container 64 from tipping over during movement and can also prevent the container 64 from being damaged by impact during movement.

[0028] The mesh plate 71 includes a handle 713 and a filter screen 712. One end of the handle 713 is provided with a hook 711. The mesh plate 71 is suspended on the metal guardrail 8 through the hook 711. When it is necessary to retrieve the precipitated material, the operation is convenient. The filter screen 712 has a sheet-like structure, which can better remove the retrieved dust. Moreover, when it is not in use, it can be suspended on the metal guardrail 8 through the hook 711, thereby preventing the operator from losing it after use.

[0029] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
