[0038] In the foundry field, resin sand is used to make molding sand and core sand when casting parts.

[0039] When making molding sand or core sand, substances such as resin, sand, flame retardants and catalysts need to be mixed together and then loaded into the mold.

[0040] The present application provides a quantitative batching sand mixing device and a sand mixing method for uniformly mixing materials such as resin, sand, flame retardant and catalyst.

[0041] In order to solve the above problems, the embodiment of the present application provides a quantitative batching sand mixing device and a sand mixing method. The solution provided by the embodiment of the present application will be described in detail below in conjunction with the drawings in the specification.

[0042] Figure 1 It is a structural schematic diagram of a quantitative batching and sand mixing device provided in one embodiment of the present application; Figure 2 yes Figure 1 Schematic diagram of the sand conveying component of the quantitative batching and sand mixing device.

[0043] Reference Figure 1 As shown, in the first aspect, the embodiment of the present application provides a quantitative batching and sand mixing device, including a sand storage component 100, a sand conveying component 200, a sand mixing component 300, a resin storage component 400, a curing agent storage component 500 and a control component 600. Among them, the sand storage component 100 is used to store sand; the sand conveying component 200 is connected to the outlet of the sand storage component 100; the sand mixing component 300 is connected to the outlet of the sand conveying component 200; the resin storage component 400 is used to store resin, which is connected to the sand mixing component 300 through a pipeline; the curing agent storage component 500 is used to store curing agent, which is connected to the sand mixing component 300 through a pipeline; the control component 600 is respectively connected to the sand storage component 100, the sand conveying component 200, the sand mixing component 300, the resin storage component 400 and the curing agent storage component 500 to control their respective actions.

[0044] For example, the resin storage component 400 includes a resin storage barrel and a pump body, and the pump body pumps the resin in the resin storage barrel into the sand mixing component 300. The curing agent storage component 500 includes a curing agent storage barrel and a pump body, and the pump body pumps the curing agent from the curing agent storage barrel into the sand mixing component 300. It is understood that the control component 600 can control the amount of resin and curing agent pumped into the sand mixing component 300 by the pump body to ensure that the sand, resin and curing agent are mixed in a fixed ratio. In addition, the amount added can be adjusted immediately according to environmental conditions and process requirements. Powders such as flame retardants can also be added through the feed port of the sand mixing component 300.

[0045] The control component 600 controls the sand conveying component 200 to convey sand to the sand mixing component 300, controls the resin storage component 400 to convey resin to the sand mixing component 300, controls the curing agent storage component 500 to convey the curing agent to the sand mixing component 300, and the sand mixing component 300 mixes the sand, resin and curing agent inside it uniformly. The device mixes sand quickly and uniformly, and the resin and curing agent can be automatically added in proportion through the liquid material control system. It is easy to operate, has strong controllability, and a high degree of automation. It is suitable for single-piece small-batch production of small and medium-sized castings, and can also be equipped with other molding equipment to form a mechanized molding production line.

[0046] For example, the control component 600 includes electrical components such as a PLC control cabinet, a contactor, and an air switch. The control component 600 is electrically connected to each component in the device. This part is prior art and will not be elaborated here. An analog display screen is provided on the PLC control cabinet to better control the working state of the quantitative batching and sand mixing device. For example, the control component 600 uses proportional integral differential control (PID) to control the ratio of the two components of the resin, and cooperates with an imported frequency converter to perform AC stepless regulation on the liquid material pump.

[0047] Reference Figure 1 The sand storage assembly 100 is vertically provided with a partition 110, which divides the sand storage space in the sand storage assembly 100 into two parts for placing different sands. For example, old sand is placed on one side and new sand is placed on the other side. The amount of new sand and old sand flowing out to the sand conveying assembly 200 is controlled by a switching gate under the sand storage assembly 100.

[0048] In addition, if Figure 1 As shown, in some examples, the outlet of the sand storage assembly 100 is provided with a sand receiving groove 700, and the sand receiving groove 700 is used to connect the outlet of the sand storage assembly 100 with the inlet of the sand conveying assembly 200. That is to say, the sand in the sand storage assembly 100 flows into the sand conveying assembly 200 through the sand receiving groove 700 at the outlet.

[0049] Reference Figure 2As shown, the sand conveying assembly 200 includes a conveying channel 210, a conveying belt 220, a power roller 230, a reversing roller 240 and a supporting roller 250. The inlet of the conveying channel 210 is connected to the outlet of the sand storage assembly 100 through the sand receiving trough 700, the power roller 230 and the reversing roller 240 are respectively arranged inside the conveying channel 210 and at both ends thereof, the conveying belt 220 is wound around the power roller 230 and the reversing roller 240, and the supporting roller 250 is arranged below the conveying belt 220 to support the conveying belt 220, so as to avoid the conveying belt 220 from sagging due to the weight of the sand and ensure normal operation. The power roller 230 can be configured as an oil-cooled power roller 230. In addition, the power roller 230 and the steering roller can be fixed by fine-tuning screws to facilitate adjustment of their positions, thereby tensioning the conveyor belt 220 to avoid excessive sagging, and ensuring that the conveyor belt 220 runs smoothly to avoid deviation.

[0050] Continue to refer to Figure 1 As shown, the quantitative batching and sand mixing device also includes a support device 800 and a rotating mechanism 900. The rotating mechanism 900 is arranged on the support device 800, and the sand conveying assembly 200 is arranged on the rotating mechanism 900. The sand conveying assembly 200 changes direction through the rotating mechanism 900. It can be understood that the support device 800 is used to support the sand conveying assembly 200, and the rotating mechanism 900 can be used to change the conveying direction of the sand conveying assembly 200, so as to facilitate the conveying of sand to a designated position. The molding and core making operation can be carried out on one side while the sand box, pattern or core box is placed on the other side. The molding and core making operation can also be moved to the other side to continue, and the lifting work of the sand box, core box and pattern can be reduced. The support device 800 can adopt a frame structure of welded steel sections, which has good rigidity, is firm and reliable, and an inspection door is opened on the seat body to facilitate the inspection of the internal liquid circuit system and circuit system.

[0051] like Figure 1 As shown, in some examples, the quantitative batching and sand mixing device further includes a quantitative detection device 1000, which is disposed in the sand conveying assembly 200. The quantitative detection device 1000 is used to monitor the amount of sand in the sand conveying assembly 200, and can alarm when there is a shortage of sand inside the sand conveying assembly 200. It is understandable that the quantitative detection device 1000 can also be disposed in the sand storage assembly 100 to monitor the amount of sand inside the sand storage assembly 100.

[0052] In addition, in some examples, reference Figure 1 As shown, the quantitative batching and sand mixing device further includes a dust removal component 1100, which is disposed at the outlet of the sand conveying component 200 to remove dust generated during the sand conveying process.

[0053] Specifically, the dust removal assembly 1100 includes a negative pressure suction device and a wet sponge, and the negative pressure suction assembly is used to guide dust to the wet sponge, and the wet sponge is used to absorb dust, thereby preventing dust from polluting the environment. At the same time, activated carbon can be set in the dust removal assembly 1100 to absorb odor.

[0054] Reference Figure 1 As shown, the sand mixing assembly 300 includes a sand mixing cylinder 310, a driving motor 320, a sand mixing spiral shaft 330 and a polluted gas adsorption assembly 340.

Specifically, the driving motor 320 is connected to the sand mixing spiral shaft 330 through a plum blossom coupling, and the driving motor 320 drives the sand mixing spiral shaft 330 to rotate, so as to mix the sand with the resin and the curing agent evenly and transport them to the outlet at the same time. In addition, the sand mixing spiral shaft 330 is provided with a sand mixing blade, and the sand mixing blade adopts a double spiral blade arrangement form, and a reverse spiral blade is partially provided, and a hard alloy blade is welded. At the same time, the liquid material (resin, curing agent) atomizing nozzle adopts external penetration type to ensure more uniform sand mixing and prevent local accumulation of liquid material.

[0055] Continue to refer to Figure 1 As shown, the quantitative batching and sand mixing device further includes a support frame 1200, which is arranged on one side of the support device 800, and the sand storage assembly 100 is arranged on the support frame 1200, and the sand storage assembly 100 is located above the sand conveying assembly 200.
