Description

Technical Field

[0001] This utility model relates to the field of slicer technology, and more specifically, to a spraying device and a slicer. Background Technology

[0002] The spray pipe of a photovoltaic slicing machine is a core component in the cutting process, mainly divided into two parts: cutting spray and blade retraction spray. The cutting spray provides cooling and lubrication during the cutting process by spraying cutting fluid, thereby ensuring cutting quality. The blade retraction spray is applied during the blade retraction process to wash away the silicon powder generated during cutting, allowing the silicon wafer to exit the wire mesh smoothly, while also ensuring slicing quality.

[0003] Traditional spray pipes have separate cutting spray and blade retraction spray designs, with the blade retraction spray located at the rear end of the cutting spray. As a result, the blade retraction spray is blocked by the cutting spray, which prevents the water flow from effectively spraying onto the silicon rod. Consequently, silicon powder generated during cutting adheres to the silicon wafer, thus affecting the slicing quality. Utility Model Content

The distance between the flow regulating plate and the bottom plate of the second structural member is adjustable to adjust the opening of the long spray nozzle.

[0013] Furthermore, both the first and second structural components are made of angle steel, with the first structural component welded to the support plate and the second structural component welded to the first structural component; or the lower spray body is an extruded aluminum profile structure.

[0027] The technical solutions in at least one embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. The following description of at least one embodiment is merely illustrative and is not intended to limit this application or its applications. Other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are all within the scope of protection of this application.

[0028] like Figures 1 to 3 As shown, an embodiment of the present invention provides a spraying device, including an upper spraying part 10 and a lower spraying part 20. The upper spraying part 10 includes an upper spraying body 11 and a plurality of nozzles 12. The plurality of nozzles 12 are spaced apart along the length direction of the upper spraying body 11, and each nozzle 12 is connected to an upper solution chamber 111 in the upper spraying body 11. The lower spraying part 20 has a lower solution chamber 211 and a long spray nozzle 212 connected to the lower solution chamber 211. The upper spraying body 11 is installed on the upper side of the lower spraying part 20, and the spraying range of the plurality of nozzles 12 avoids the lower spraying part 20.

[0029] In this design, nozzles 12 are provided to facilitate the spraying of fluid from the upper solution chamber 111 to achieve cooling or lubrication functions. The nozzles 12 also improve spraying accuracy. Multiple nozzles 12 are spaced apart along the length of the upper spray body 11, which greatly improves spraying efficiency. The fluid in the lower solution chamber 211 flows out through the long spray nozzle 212. The upper spray body 11 is installed on the upper side of the lower spray section 20. The spray range of the multiple nozzles 12 can avoid the lower spray section 20, solving the problem of obstruction between adjacent spray sections, significantly improving spraying efficiency, and thus improving product quality.

[0030] When the spraying device is used to cut silicon rods, fluid is sprayed from the upper solution chamber 111 through the nozzles 12 to flush away the silicon powder generated during cutting. Multiple nozzles 12 are spaced apart along the length of the upper spraying body 11, which improves the spraying efficiency. The fluid in the lower solution chamber 211 flows out through the long spray nozzles 212 to provide cooling and lubrication. The upper spraying body 11 is installed on the upper side of the lower spraying part 20, and the spraying range of the multiple nozzles 12 can avoid the lower spraying part 20, which solves the problem of the cutting spray blocking the retraction spray, improves the flushing effect of the retraction spray on the silicon powder generated during cutting, thereby improving the spraying efficiency and product quality, while avoiding the problem of the retraction tool getting stuck.

[0031] like Figure 2 As shown, the upper spray section 10 also includes an adjustment structure 13, which is connected to the upper spray body 11 and / or multiple nozzles 12 to adjust the spray angle of the multiple nozzles 12. By adjusting the spray angle of the multiple nozzles 12 through the adjustment structure 13, the fluid direction can be adjusted according to the real-time spraying requirements, thus ensuring spraying efficiency.

[0032] In this embodiment, the adjustment structure 13 includes a hinge 131, a fixing plate 132, and an adjustment member 133. The upper spray body 11 is rotatably connected to the lower spray part 20 via the hinge 131. The fixing plate 132 is fixedly installed and has an adjustment hole 1321. The adjustment member 133 is installed on the side of the upper spray body 11 away from the hinge 131, and the adjustment member 133 passes through the adjustment hole 1321 and is connected to the fixing plate 132. The installation position of the adjustment member 133 in the adjustment hole 1321 is adjustable.

[0033] The upper spray body 11 is rotatably connected to the lower spray section 20 via a hinge 131, allowing adjustment of the spray angle of the upper spray body 11 to prevent the lower spray section 20 from obstructing the upper spray section 10. The installation position of the adjusting member 133 within the adjusting hole 1321 is adjustable, and the adjusting hole 1321 limits the movement range of the adjusting member 133 to prevent the upper spray body 11 from rotating too much, making it difficult to control the direction of the spray fluid. Specifically, the fixing plate 132 has three scale lines above the adjusting hole 1321 to display the rotation angle of the upper spray body 11 and control the rotation angle to be between 0° and 12°.

[0034] In this embodiment, the adjusting hole 1321 is an oblong or arc-shaped hole, the spray nozzle 12 has a fan-shaped nozzle, and the upper spray body 11 is formed by processing a square tube. The oblong or arc-shaped adjusting hole 1321 facilitates the rotation of the upper spray body 11 and also facilitates the recording of the rotation angle; the fan-shaped nozzle of the nozzle 12 makes the spray water flow more flat, which facilitates the concentration of water flow and improves the spraying efficiency and accuracy; the upper spray body 11 is formed by processing a square tube, which improves its mechanical properties, makes it less prone to deformation, and extends the service life of the equipment.

[0035] like Figure 2 , Figure 3 As shown, the lower spray section 20 includes a lower spray body 21 and a flow regulating plate 22 mounted on the lower spray body 21. The lower spray body 21 has a lower solution chamber 211 and a long spray nozzle 212. The flow regulating plate 22 is used to adjust the opening of the long spray nozzle 212. The upper spray body 11 is mounted on the upper surface of the lower spray body 21, and the flow regulating plate 22 is located below multiple nozzles 12. By changing the distance between the flow regulating plate 22 and the bottom plate of the lower spray body 21, the opening of the long spray nozzle 212 is adjusted, thereby controlling the flow rate and distribution of the spray fluid, ensuring the spraying effect, making the spray flow more uniform, and improving product quality.

[0036] like Figure 3 As shown, the lower spray body 21 includes a support plate 213, a first structural member 214, and a second structural member 215. The upper spray body 11 is mounted on the upper side of the support plate 213. The first structural member 214 is disposed on the lower side of the support plate 213, and the second structural member 215 is disposed on the lower side of the first structural member 214. A first cavity 2111 is formed between the first structural member 214 and the support plate 213, and a second cavity 2112 is formed between the first structural member 214, the second structural member 215, and the support plate 213. The spray liquid received in the first cavity 2111 is transported to the second cavity 2112. A long spray nozzle 212 is formed by the gap between the lower end of the support plate 213 and the second structural member 215. Through multi-stage flow diversion and slow-flow settings, the uniform distribution of the spray fluid is ensured, improving the spraying effect, significantly enhancing the uniformity and stability of the spraying, and further improving product quality.

[0037] like Figure 2 As shown, the side wall of the first structural member 214 has a fluid inlet 2141, and the bottom wall of the first structural member 214 has a plurality of diversion holes 2142. The plurality of diversion holes 2142 are spaced apart along the length direction of the first cavity 2111, and the plurality of diversion holes 2142 connect the first cavity 2111 and the second cavity 2112. The lower spray body 21 also includes a plurality of slow-flow baffles 216, which are distributed on the inner wall of the second cavity 2112.

[0038] Multiple diversion holes 2142 are arranged at intervals along the length of the first cavity 2111. Water flowing into the first cavity 2111 from the fluid inlet 2141 enters the second cavity 2112 through the multiple diversion holes 2142, which plays a buffering role for the fluid. Multiple flow-slowing baffles 216 are set to further buffer the fluid, which not only avoids the vibration of the equipment caused by fluid impact, affecting the operation and service life of the equipment, but also ensures the continuous and stable flow of the spray fluid and avoids the phenomenon of flow interruption.

[0039] like Figure 2 , Figure 3 As shown, the support plate 213 includes an inclined plate 2131 and a folded plate 2132. The inclined plate 2131 is inclined relative to the horizontal plane. The upper spray body 11 is installed on the upper side of the inclined plate 2131. The first structural member 214 is installed on the lower side of the inclined plate 2131. The upper end of the folded plate 2132 is connected to the lower end of the inclined plate 2131. The gap between the lower end of the folded plate 2132 and the bottom plate of the second structural member 215 forms a long spray nozzle 212. The flow regulating plate 22 is installed on the folded plate 2132. The distance between the flow regulating plate 22 and the bottom plate of the second structural member 215 is adjustable to adjust the opening of the long spray nozzle 212.

[0040] An inclined plate 2131 is set to separate the upper spray body 11 and the first structural component 214, while also serving as a guide and support. The upper end of the folding plate 2132 is connected to the lower end of the inclined plate 2131. This arrangement optimizes the internal structure of the equipment. The downward setting of the folding plate 2132 avoids obstructing the upper spray section 10. The opening of the long spray nozzle 212 is adjusted by setting a flow regulating plate 22. The liquid flow rate at the long spray nozzle 212 is controlled according to the inlet flow rate and the required spray flow rate to avoid flow interruption and achieve a better spraying effect.

[0041] In this embodiment, the first structural component 214 and the second structural component 215 are both made of angle steel. The first structural component 214 is welded to the support plate 213, and the second structural component 215 is welded to the first structural component 214; or the lower spray body 21 is an extruded aluminum profile structure.

[0042] Both the first structural component 214 and the second structural component 215 are made of angle steel, which can reduce the volume and avoid obstructing the upper spray section 10, while also increasing the buffer cross-sectional area to further buffer the fluid and ensure the continuity of the fluid. The first structural component 214 is welded to the support plate 213, and the second structural component 215 is welded to the first structural component 214. This arrangement improves the reliability of the connection between components and enhances the structural strength.

[0043] In this embodiment, the lower spray body 21 or the flow regulating plate 22 has multiple elongated mounting holes. The lower spray part 20 also includes multiple fasteners 23, each of which passes through a mounting hole. The flow regulating plate 22 is connected to the lower spray body 21 through multiple fasteners 23. The relative positions of the fasteners 23 and the corresponding mounting holes are adjustable to adjust the position of the flow regulating plate 22. By changing the position of the flow regulating plate 22, the area of ​​the flow regulating plate 22 blocking the long spray nozzle 212 is changed, thereby adjusting the opening of the long spray nozzle 212.

[0044] The position of the flow regulating plate 22 is adjusted by adjusting the relative position of the fastener 23 in the corresponding mounting hole, thereby adjusting the opening of the long spray nozzle 212. When the flow regulating plate 22 is adjusted upward, the opening of the long spray nozzle 212 increases, and the liquid flow rate increases; when the flow regulating plate 22 is adjusted downward, the opening of the long spray nozzle 212 decreases, and the liquid flow rate decreases.

[0045] In this embodiment, a sealing gasket 30 is provided between the flow regulating plate 22 and the lower spray body 21. The bottom plate of the lower spray body 21 protrudes from the long spray nozzle 212. The distance between the flow regulating plate 22 and the bottom plate of the lower spray body 21 is adjustable to adjust the opening of the long spray nozzle 212. The flow regulating plate 22 can be a flat plate or an L-shaped plate. By providing the sealing gasket 30, the sealing performance between the flow regulating plate 22 and the lower spray body 21 is improved. Specifically, when the flow regulating plate 22 is an L-shaped plate, the longer transition structure makes the spray fluid in the lower spray body 21 more stable. However, since the L-shaped plate has high requirements for flatness, when the requirements for the slow flow effect are lower, the flow regulating plate 22 can be a flat plate, which is convenient for processing and manufacturing, and saves production costs.

[0046] An embodiment of this utility model also provides a slicing machine, which includes a wire mesh and the aforementioned spraying device. The spraying device consists of two symmetrically arranged sets, with the wire mesh located between the two sets of spraying devices. The upper spraying section 10 is used for blade retraction spraying, and the lower spraying section 20 is used for cutting spraying. This arrangement satisfies the cooling and lubrication requirements during cutting and blade retraction. Furthermore, the integrated design optimizes the structural layout of the spraying device, improving the compactness and ease of operation of the equipment. This significantly enhances the cooling and lubrication effects during cutting and blade retraction, reduces wire jamming, and improves cutting quality and production efficiency.
