Description

Technical Field

[0001] The invention belongs to the field of cooling devices, in particular to a cooling device for manufacturing hardware products. Background Art

[0002] Small hardware products will be in a high temperature state after heat treatment and other steps. In order to speed up the processing efficiency of hardware products, human intervention is required. Therefore, cooling equipment is first needed to accelerate the cooling process to ensure that the product will not cause danger to the transportation tools or operators during quality inspection, packaging and transportation. Traditional technology usually uses air cooling structure to remove the heat in the hardware products.

[0003] A patent document with announcement number CN114130906B discloses a workpiece cooling device for hardware production. An air-cooling bin and a water-cooling bin are provided inside the main shell. A cooling fan is installed on the top of the air-cooling bin, and heat exchangers are provided on both sides of the inside of the air-cooling bin. A water pan is provided on the top of the inner cavity of the water-cooling bin, and an air-drying fan is installed at the bottom of the water pan. A nozzle is provided at the bottom of the water pan, and a feeding drawer is slidably connected to the water-cooling bin.

[0004] In order to save the preparation time of hardware products in traditional technology, high-temperature hardware products during preparation or processing are transported and cooled at the same time. That is, the heat of the hardware products during transportation is removed by air cooling, water cooling or a combination of the two. Water cooling provides a low-temperature environment for the air-cooled structure. However, in this process, the water-cooled structure is affected by the heat of the hardware, and its internal water temperature will change. The sudden change in temperature will affect the cooling effect of the air-cooled structure to a certain extent. When the temperature around the high-temperature hardware keeps changing, it may affect the hardware's own state, resulting in adverse conditions such as thermal stress damage or microstructural changes.

[0005] To this end, the present invention provides a cooling device for manufacturing hardware products. Summary of the invention

[0008] The inner part of the outer cover is provided with a plurality of through slots, and a plurality of exhaust assemblies are installed above the corresponding through slots. A plurality of blocking bars are installed on the outer side of the metal conveyor belt, and hardware products to be cooled are placed on the metal conveyor belt. The inner part of the outer cover is also provided with a plurality of exhaust slots 1 and 2.

[0009] Preferably, an arched cavity is opened inside the outer cover, and the arched cavity is connected with a plurality of through grooves. The exhaust assembly includes a protective frame cover fixedly installed above the outer cover, and the protective frame cover covers the top of the corresponding through grooves. A cooling exhaust fan is installed inside the protective frame cover.

[0010] Preferably, an air guide structure is movably installed inside the through slot, and the exhaust slot one and the exhaust slot two are connected to the through slot.

[0011] Preferably, a groove is opened inside the air guide structure, and the air guide structure is lifted and installed inside the through groove. When the air guide structure is in the highest position, the groove opened in the air guide structure is connected with exhaust groove one. When the air guide structure is in the lowest position, the groove opened in the air guide structure is connected with exhaust groove two.

[0012] Preferably, the air guide structure comprises an air guide ring, wherein a semi-arc through groove and an air guide arc-shaped groove are provided inside the air guide ring, wherein the semi-arc through groove penetrates the air guide ring, and the air guide arc-shaped groove is connected with the semi-arc through groove.

[0013] Preferably, a sliding block is fixedly installed on the outer bottom of the air guide ring, a lifting rod is fixedly installed above the sliding block, a lifting groove is opened inside the through groove, the sliding block is slidably installed inside the lifting groove, and the upper end of the lifting rod is connected to the top wall inside the lifting groove.

[0014] Preferably, the inner top of the outer cover is provided with a plurality of connecting chambers one, two and three, and the connecting chambers one, two and three are wrapped around the outer sides of the corresponding through grooves, and the water chamber is connected with the plurality of connecting chambers one, two and three.

[0015] Preferably, the connecting chamber 1 is located above the exhaust slot 1, the connecting chamber 2 is located between the exhaust slot 1 and the exhaust slot 2, and the connecting chamber 3 is located below the exhaust slot 2.

[0016] Preferably, a bottom arc groove and an outwardly expanding arc groove are provided at the inner bottom of the air guide ring, and the semi-arc through groove, the air guide arc groove, the outwardly expanding arc groove and the bottom arc groove are connected.

[0017] Preferably, the width of the bottom arc groove is smaller than the width of the outward-expanding arc groove, the connection between the bottom arc groove and the outward-expanding arc groove is smoothly arranged, and the bottom width of the outward-expanding arc groove is smaller than the top width of the outward-expanding arc groove.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. A cooling device for manufacturing hardware products described in the present invention is driven by an exhaust assembly to generate suction to take away the heat of the hardware products inside the outer cover. Since the water cavity arranged inside the outer cover realizes water circulation through circulating water tank 1 and circulating water tank 2, the low temperature environment inside the outer cover can be maintained, and the air cooling effect of the exhaust assembly can be enhanced. The exhaust assembly is driven to exhaust air outwards, and a part of this wind can be diverted by exhaust slot 1 and exhaust slot 2. The wind flow released from exhaust slot 1 and exhaust slot 2 will cool the water inside the water cavity, that is, the air cooling structure and the water cooling structure cooperate with each other, which improves the cooling efficiency of the hardware products and does not cause the water used for water cooling to gradually heat up, thereby reducing the effect of the water cooling structure.

[0020] 2. The cooling device for manufacturing hardware products described in the present invention will rise from the middle of the air guide ring and the semi-arc through groove through wind force. Since the semi-arc through groove and the air guide arc groove are in a connected state, a part of the wind force will be diverted from the semi-arc through groove and discharged from the air guide arc groove. When the lifting rod is in a natural state, the air guide arc groove is connected with the second exhaust groove, and the wind flow released from the air guide arc groove will be released through the second exhaust groove, thereby dissipating the heat of the circulating water in the lower part of the water cavity, ensuring that the circulating water inside the water cavity will not heat up.

[0021] 3. The cooling device for manufacturing hardware products described in the present invention can dissipate the heat of circulating water in the upper inner part of connecting chamber one and connecting chamber two when the wind is released from one exhaust slot; and can dissipate the heat of circulating water in the inner bottom of connecting chamber two and inside connecting chamber three when the wind is released from the second exhaust slot. In order to maintain the air-cooling effect of the exhaust assembly, a large amount of air is required to carry the heat of the hardware products and be exhausted from the through slot. Therefore, in order not to affect the air-cooling effect of the exhaust assembly, only a small part of the wind can be diverted by the wind guide structure. Therefore, by setting a lifting wind guide structure to release the wind from exhaust slot one or exhaust slot two, the cooling of the hardware products can be achieved more effectively.

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0033] Embodiment 1

[0034] like Figure 1-Figure 3 and Figure 5 As shown, a cooling device for manufacturing hardware products according to an embodiment of the present invention comprises a metal conveyor belt 1 and an outer cover 5 installed on the metal conveyor belt 1, a plurality of exhaust components 4 are installed above the outer cover 5, a circulating water tank 1 2 and a circulating water tank 2 3 are installed on both sides of the outer cover 5, a water delivery pipe 31 is installed at the end of the circulating water tank 2 3, the circulating water tank 1 2 and the circulating water tank 2 3 are components made of the same structure, a water cavity 7 is opened inside the outer cover 5, the circulating water tank 1 2 is connected to the water cavity 7 through the water delivery pipe 31, and the water inside the circulating water tank 1 2, the circulating water tank 2 3 and the water cavity 7 forms a water circulation operation;

[0035] A plurality of through slots 52 are formed inside the outer cover 5, a plurality of exhaust assemblies 4 are installed above the corresponding through slots 52, a plurality of barrier bars 11 are installed on the outer side of the metal conveyor belt 1, hardware products to be cooled are placed on the metal conveyor belt 1, and a plurality of exhaust slots 1 53 and 2 54 are also formed inside the outer cover 5.

[0036] Specifically, the hardware products being prepared or completed will carry high temperatures. When these hardware products need to be transported, they are first placed on the metal conveyor belt 1 and between the two blocking bars 11. The blocking bars 11 are responsible for blocking the hardware products to prevent the hardware products from changing positions and bumping during transportation. After the hardware products move to the inside of the outer cover 5, the exhaust assembly 4 is driven to generate suction to take away the heat of the hardware products inside the outer cover 5. Because the water cavity 7 arranged inside the outer cover 5 realizes water circulation through the circulating water tank 1 2 and the circulating water tank 2 3, the low temperature environment inside the outer cover 5 can be maintained, thereby increasing the heat. The strong exhaust component 4 has an air cooling effect. The exhaust component 4 drives the air to be exhausted outward. A part of this wind can be diverted by the exhaust slot 1 53 and the exhaust slot 2 54. The wind flow released from the exhaust slot 1 53 and the exhaust slot 2 54 will cool the water inside the water cavity 7. That is, the air cooling structure and the water cooling structure cooperate with each other, which improves the cooling efficiency of the hardware products and does not cause the water used for water cooling to gradually heat up, thereby reducing the effect of the water cooling structure. In addition, the setting of multiple exhaust slots 1 53 and exhaust slots 2 54 is used to quickly act on the cooling water inside the water cavity 7 to avoid large changes in the cooling water temperature, thereby changing the cooling temperature of the hardware and causing damage to the hardware.

[0037] like Figure 2-Figure 3 As shown, an arched cavity 51 is opened inside the outer cover 5, and the arched cavity 51 is connected with a plurality of through grooves 52. The exhaust assembly 4 includes a protective frame cover 41 fixedly installed above the outer cover 5, and the protective frame cover 41 covers the top of the corresponding through grooves 52. A cooling exhaust fan 42 is installed inside the protective frame cover 41, and an air guide structure 6 is movably installed inside the through groove 52. Exhaust groove 1 53 and exhaust groove 2 54 are connected with the through groove 52.

[0038] Specifically, when the inside of the outer cover 5 needs to be cooled, the cooling exhaust fan 42 is driven by electricity to rotate at a high speed, thereby generating a suction force on the hardware products, taking away the heat carried by the hardware products, and cooling them. The arched setting of the arched cavity 51 allows the air inside the outer cover 5 to be discharged more effectively through the through groove 52. During the exhaust process inside the through groove 52, the air can be guided by the air guide structure 6, so that a part of the wind force is diverted and released from the exhaust groove 1 53 and the exhaust groove 2 54.

[0039] like Figure 4-Figure 5 As shown, a groove is opened inside the air guide structure 6, and the air guide structure 6 is lifted and installed inside the through groove 52. When the air guide structure 6 is in the highest position, the groove opened in the air guide structure 6 is connected with the exhaust groove 1 53. When the air guide structure 6 is in the lowest position, the groove opened in the air guide structure 6 is connected with the exhaust groove 2 54.

[0040] The air guide structure 6 includes an air guide ring 61 , and a semi-arc through groove 62 and an air guide arc groove 63 are provided inside the air guide ring 61 . The semi-arc through groove 62 penetrates the air guide ring 61 , and the air guide arc groove 63 is connected to the semi-arc through groove 62 .

[0041] A sliding block 65 is fixedly installed on the outer bottom of the air guide ring 61, and a lifting rod 64 is fixedly installed above the sliding block 65. A lifting groove 521 is opened inside the through groove 52, and the sliding block 65 is slidably installed inside the lifting groove 521. The upper end of the lifting rod 64 is connected to the inner top wall of the lifting groove 521.

[0042] Specifically, when the air inside the outer cover 5 is discharged through the through groove 52, the wind will rise from the middle of the air guide ring 61 and the semi-arc through groove 62. Because the semi-arc through groove 62 and the air guide arc groove 63 are connected, the wind will be diverted from the semi-arc through groove 62 and discharged from the air guide arc groove 63. When the lifting rod 64 is in a natural state, the air guide arc groove 63 is connected with the exhaust groove 2 54, and the wind flow released from the air guide arc groove 63 will be released through the exhaust groove 2 54, thereby dissipating the heat of the circulating water in the lower part of the water chamber 7, ensuring that the circulating water in the water chamber 7 will not heat up. When the lifting rod 64 is in a retracted state, the air guide arc groove 63 is connected with the exhaust groove 1 53, that is, the wind flow released from the semi-arc through groove 62 will be released from the air guide arc groove 63 and the exhaust groove 1 53 at this time, thereby dissipating the heat of the circulating water in the upper part of the water chamber 7.

[0043] like Figure 5 As shown, the inner top of the outer cover 5 is provided with a plurality of connecting chambers 1 71 , 72 and 73 , which are wrapped around the outer sides of the corresponding through grooves 52 , and the water chamber 7 is connected with the plurality of connecting chambers 1 71 , 72 and 73 .

[0044] The connecting chamber 1 71 is located above the exhaust slot 1 53 , the connecting chamber 2 72 is located between the exhaust slot 1 53 and the exhaust slot 2 54 , and the connecting chamber 3 73 is located below the exhaust slot 2 54 .

[0045] Specifically, when the wind is released from the exhaust slot 1 53, the circulating water in the upper inner position of the connecting chamber 1 71 and the connecting chamber 2 72 will be cooled. When the wind is released from the exhaust slot 2 54, the circulating water in the inner bottom of the connecting chamber 2 72 and the connecting chamber 3 73 will be cooled. In order to maintain the air-cooling effect of the exhaust component 4, a large amount of air is required to carry the heat of the hardware products and exhaust them from the through slot 52. Therefore, in order not to affect the air-cooling effect of the exhaust component 4, only a small part of the wind can be diverted by the air guide structure 6. Therefore, by setting a lifting air guide structure 6 to release the wind from the exhaust slot 1 53 or the exhaust slot 2 54, the cooling of the hardware products can be achieved more effectively.

[0046] Embodiment 2

[0047] like Figure 6-Figure 8 As shown, compared with Example 1, another implementation of the present invention is: the inner bottom of the air guide ring 61 is provided with a bottom arc groove 67 and an outward arc groove 66, and the semi-arc through groove 62, the air guide arc groove 63, the outward arc groove 66 and the bottom arc groove 67 are connected.

[0048] The width of the bottom arc groove 67 is smaller than the width of the outwardly expanding arc groove 66 . The connection between the bottom arc groove 67 and the outwardly expanding arc groove 66 is smoothly arranged. The bottom width of the outwardly expanding arc groove 66 is smaller than the top width of the outwardly expanding arc groove 66 .

[0049] Specifically, when the exhaust component 4 is performing air cooling, the wind flow will rise from the bottom of the air guide structure 6 to the top of the air guide structure 6, so the wind flow will first enter the bottom arc groove 67, and the wind flow will rise and accumulate inside the bottom arc groove 67. When the wind flow rises to the inside of the outward-expanding arc groove 66, due to the gradually expanding cavity design of the outward-expanding arc groove 66, the wind flow rising from the bottom arc groove 67 will show an outward-expanding rise inside the outward-expanding arc groove 66, so that the wind flow can more easily rise from the outward-expanding arc groove 66 to the position of the air guide arc groove 63, and then the air guide arc groove 63 has a diversion effect.

[0050] Working principle: the hardware products being prepared or completed will carry high temperature themselves. When these hardware products need to be transported, they are first placed on the metal conveyor belt 1 and between the two blocking bars 11. The blocking bar 11 is responsible for blocking the hardware products to prevent the hardware products from changing position and bumping during transportation. After the hardware products move to the inside of the outer cover 5, the exhaust component 4 is driven to generate suction to take away the heat of the hardware products inside the outer cover 5. Because the water cavity 7 arranged inside the outer cover 5 realizes water circulation through the circulating water tank 1 2 and the circulating water tank 2 3, the low temperature environment inside the outer cover 5 can be maintained, and the wind cooling effect of the exhaust component 4 can be enhanced. The exhaust component 4 is driven to exhaust air outward. A part of this wind can be diverted by the exhaust slot 1 53 and the exhaust slot 2 54. The wind flow released from the exhaust slot 1 53 and the exhaust slot 2 54 will cool the water inside the water cavity 7, that is, the air cooling structure and the water cooling structure cooperate with each other, that is, The cooling efficiency of the hardware products is improved, and the water used for water cooling will not gradually heat up, thereby reducing the effect of the water cooling structure. When the air inside the outer cover 5 is discharged through the through groove 52, the wind will rise from the middle of the air guide ring 61 and the semi-arc through groove 62. Because the semi-arc through groove 62 and the air guide arc groove 63 are in a connected state, at this time, a part of the wind will be diverted from the semi-arc through groove 62 and discharged from the air guide arc groove 63. When the lifting rod 64 is in a natural state, the air guide arc groove 6 3 is connected with the exhaust slot 2 54, and the wind flow released from the wind guide arc groove 63 will be released through the exhaust slot 2 54, thereby dissipating the heat of the circulating water in the lower part of the water chamber 7, ensuring that the circulating water in the water chamber 7 will not heat up. When the lifting rod 64 is in a retracted state, the wind guide arc groove 63 is connected with the exhaust slot 1 53, that is, the wind flow released from the semi-arc through groove 62 will be released from the wind guide arc groove 63 and the exhaust slot 1 53 at this time, thereby dissipating the heat of the circulating water in the upper part of the water chamber 7.

[0051] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
