Description

Technical Field

[0001] The utility model belongs to the technical field of shot blasting equipment, and particularly relates to a blanking component of a shot blasting machine. Background Art

[0002] Shot blasting machines utilize high-speed projectiles to clean or strengthen the surface of workpieces. They can simultaneously remove sand, core, and clean castings. They are also used for surface treatment of forgings, aluminum-magnesium alloys, and sheet metal weldments. Almost all steel castings, gray castings, malleable cast iron parts, and iron ball castings require shot blasting. This not only removes surface scale and grit, but also serves as an essential preparatory step before casting quality inspection.

[0003] like Figure 3 As shown, the Chinese patent application number CN202022139957.8 discloses a feeding device for a shot blasting machine, including an installation and fixing assembly, including a vertically placed fixed base and a fixed support rod fixedly connected to the fixed base, a hopper assembly including a hopper body fixedly connected to the support rod and a coarse material pipe connected to the bottom of the hopper body, the feeding assembly including a first discharge pipe and a second discharge pipe connected to both sides of the hopper body, a coarse material storage box, the end face of the coarse material pipe is connected and fixed to the top surface of the fixed base, and a grading screening assembly including a primary screen arranged on the inner side wall of the hopper body, a secondary screen connected to the primary screen, and an inclined guide plate located directly below the primary screen and the secondary screen.

[0004] Since the discharge pipe is straight and the reserved size of the discharge port of the hopper combined with the discharge pipe is small, its structural design only considers the situation where steel shots without debris can pass through smoothly, and does not consider other debris such as welding wire heads, drilling iron filings, etc. that may be generated during shot blasting.

[0005] However, the above debris often clogs the discharge port, accumulates more and more, and eventually the steel shots will be blocked in the discharge port and unable to enter the shot blasting chamber, resulting in unsatisfactory shot blasting effect and failure to meet the qualified standards for shot blasting and rust removal of products. It is necessary to manually remove the debris frequently, which brings troubles to production operations. Utility Model Content

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A blanking assembly for a shot blasting machine, comprising:

[0008] hopper;

[0009] At least one guide bin is provided and connected to the bottom of the hopper, and the guide bin is funnel-shaped;

[0010] The material guide bin has a discharge end;

[0011] A downcomer is connected below the material guiding bin by cooperating with the discharge end through a fastener.

[0012] Further, the plane where the discharge end is located has a certain angle with the center line of the material guiding bin.

[0013] Further, the cross section of the material guiding bin is inverted trapezoidal.

[0014] Further, the front end of the downcomer has a material collecting neck at the connection with the material guiding bin.

[0015] Further, a hose is connected to the end of the downcomer.

[0016] Further, there are four material guiding bins, which are arranged in sequence along the length direction of the hopper.

[0017] Compared with the prior art, the present application has the following beneficial effects:

[0018] The technical scheme adds a material guiding bin between the hopper and the downcomer, which plays a guiding role for the steel shots, welding wire heads, iron scraps and other sundries placed inside. Compared with the original small-diameter downcomer, the added material guiding bin has a large-diameter discharge end, which cooperates with the downcomer to avoid the accumulation of sundries and affect the feeding of the steel shots.

[0019] The material guiding bin is funnel-shaped, large at the top and small at the bottom. When sundries are generated, the sundries will not accumulate at the discharge end, but will enter the shot blasting chamber together with the steel shots through the downcomer, so as to achieve the purpose of automatically removing the sundries and ensure the polishing quality of the product.

[0029] like Figure 1 - Figure 2 As shown, a discharge assembly of a shot blasting machine of the present invention comprises a hopper 1, a guide bin 2 and a discharge pipe 3;

[0030] The guide bin 2 is provided with at least one and is connected to the bottom of the hopper 1;

[0031] The material guide bin 2 has a discharge end;

[0032] The discharge pipe 3 is connected to the bottom of the guide bin 2 through the cooperation of the fastener 4 and the discharge end.

[0033] This technical solution adds a guide bin 2 between the hopper 1 and the discharge pipe 3, which guides the steel shots, welding wire heads, iron filings and other debris placed inside. Compared with the original small-diameter discharge port, the added guide bin 2 has a larger-diameter discharge end and cooperates with the discharge pipe 3 to avoid the accumulation of debris and affect the feeding of steel shots.

[0034] The guide bin 2 is funnel-shaped, with a large top and a small bottom. When debris is generated, the debris 5 will not accumulate at the discharge end. Figure 5 As shown, through the discharge pipe 3, the debris 5 will enter the shot blasting chamber together with the steel shot, so as to achieve the purpose of automatically removing the debris 5 and ensure the polishing quality of the product.

[0035] Specifically, there is a certain angle between the plane where the discharge end is located and the center line of the guide bin 2. Such an arrangement allows the discharge pipe 3 to be tilted after being combined with the guide bin 2, adapting to the angle of the feed port of the shot blasting room in actual production.

[0036] The guide bin 2 is generally funnel-shaped, and its outline includes but is not limited to a cone or an inverted trapezoidal cross section.

[0037] like Figure 1 As shown, a material collection neck 30 is provided at the connection between the front end of the discharge pipe 3 and the material guide bin 2 , and the material collection neck 30 plays the role of an arc transition.

[0038] In addition, in this actual production process, a hose (not shown) can be connected to the end of the discharge pipe 3. On the one hand, the length of the discharge pipe 3 can be increased and the discharge angle of the steel shot can be adjusted. On the other hand, the steel shot can be guided to the collection box or shot blaster through the hose for collection.

[0039] There can be multiple material guide bins 2, specifically four in this embodiment, and they are arranged equidistantly along the length direction of the hopper 1. This arrangement can simultaneously discharge materials into multiple shot blasting rooms, thereby improving work efficiency.

[0040] like Figure 2 As shown, the fasteners 4 can be bolts. At the junction of the guide bin 2 and the discharge pipe 3, a disc-shaped piece similar to a flange is provided, and a plurality of screw holes are provided on the upper end. The discharge pipe 3 is connected to the bottom of the guide bin 2 by bolts. Such a detachable connection form is convenient for replacing the discharge pipe materials of different diameters according to the needs of the polishing work to adapt to steel shots with larger particle sizes.

[0041] By improving the guide bin 2, compared with Figure 4 In terms of the existing small-diameter discharge port, the additional guide bin has a larger-diameter discharge end and cooperates with the discharge pipe to avoid the accumulation of debris 5 and affect the feeding of steel shots. Figure 5 shown.

[0042] The connection between the hopper 1 and the guide bin 2 can be riveted, welded, bolted or other connection methods, without any specific limitation.

[0043] The above are only embodiments of the present invention. Common knowledge such as the known specific structures and characteristics in the scheme is not described in detail here. Ordinary technicians in the relevant field are aware of all common technical knowledge in the technical field of the utility model before the application date or priority date, can obtain all existing technologies in the field, and have the ability to apply conventional experimental means before that date. Ordinary technicians in the relevant field can improve and implement this scheme based on their own abilities under the guidance of this application. Some typical known structures or methods should not become obstacles for ordinary technicians in the relevant field to implement this application. It should be pointed out that for those skilled in the art, without departing from the structure of the utility model, they can also make several variations and improvements, which should also be regarded as the scope of protection of the utility model. These will not affect the effect of the implementation of the utility model and the practicality of the patent.
