Description
Technical Field
[0001] This utility model relates to the field of wire cutting and sanding technology, and in particular to a novel diamond wire sanding machine. Background Technology
[0002] Diamond wire has been widely used in the squaring and cutting of raw materials such as photovoltaic silicon wafers, sapphire and magnetic materials. Among them, the improvement of the sand coating quality and cost of diamond wire plays a vital role in the continuous progress of related industries.
[0003] A traditional diamond wire sand plating machine consists of a wire feeding control cabinet, a degreasing unit, an acid pickling unit, a pre-plating unit, a sand plating unit, a nickel plating unit, a washing and drying unit, and a take-up control cabinet. The sand plating unit, nickel plating unit, and washing and drying unit are the core of the equipment. In the sand plating unit, the diamond wire passes through a sand pile in the sand plating cylinder and is immersed in the sand plating solution, achieving sand plating using the principle of electrolysis. After use, the sand plating solution first flows into an overflow cylinder for preliminary sedimentation, then is treated in a sand plating return water tank, and finally enters a centrifugal pump and a chemical filter, ultimately achieving recycling. In the nickel plating unit, the diamond wire is repeatedly wound onto conductive rollers at both ends of the nickel plating tank. The wire between the two conductive rollers is immersed in the nickel plating tank to complete the nickel plating. The conductive rollers adopt a narrow wire zone structure. The nickel plating tank adopts a shallow tank structure. A nickel plating return water tank is set below the nickel plating tank to recover the nickel plating solution, which is then treated by a chemical filter, ultimately achieving recycling. In the washing and drying unit, diamond wire is wound around single-groove guide pulleys at both ends of the drying chamber. The two guide pulleys support the three segments of diamond wire reciprocating between them as they enter the chamber for drying.
[0004] In existing technology, during the sand plating unit, corundum (carborundum) enters the overflow cylinder along with the diamond wire and the flow of the plating solution. The impact and turbulence of the water flow in the overflow cylinder cause a small amount of corundum to enter the plating return water tank. With prolonged use, the centrifugal pump connected to the plating return water tank is easily clogged by corundum, potentially leading to structural damage. These issues also clog the filter elements of the chemical filter, increasing the frequency of filter element replacement, significantly increasing production costs, and severely disrupting production stability.
[0005] The conductive rollers in the nickel plating unit employ a narrow wire zone structure, limiting the number of turns the diamond wire can make. During the nickel plating process, the overall path of the wire immersed in the nickel plating tank is relatively short, and the immersion time is insufficient, often resulting in the coating's durability failing to meet expectations.
[0006] During the nickel plating process, the diamond wire inevitably experiences slight friction and vibration as it travels around the plating bath, causing the diamond wire to shed abrasive particles. These abrasive particles are then recycled into the nickel plating return water tank along with the nickel plating solution. The outlet pipe at the bottom of the tank guides the abrasive-containing solution into the chemical filter, which then clogs the filter element, further increasing production costs.
[0007] The guide wheels at both ends of the drying chamber have a single-groove structure, which only allows the diamond wire to pass through the drying chamber three times. When the moisture content on the diamond wire surface changes, the drying effect is not ideal.
[0008] To address the above problems, a new type of diamond wire sand plating machine is proposed. Utility Model Content
[0009] To overcome the above deficiencies, this utility model provides a novel diamond wire sand plating machine, aiming to improve the problems in the existing technology, such as diamond abrasive clogging the centrifugal pump and filter element in the sand plating unit; insufficient wire immersion time and unsatisfactory coating durability in the nickel plating unit; diamond wire shedding and clogging the filter element in the nickel plating unit; and unsatisfactory drying effect in the water washing and drying unit.

[0013] The improved nickel plating unit includes a frame two, a deep-groove nickel plating tank is installed on the top of the frame two, and wide-line area conductive roller two and wide-line area conductive roller one are respectively arranged on both sides of the deep-groove nickel plating tank. An isolation pool is installed on the lower inner side of the frame two, and a nickel plating return water pool is installed on the lower inner side of the frame two. Two chemical agent filters are arranged on the left side of the frame two.
[0014] As a further description of the above technical solution:
[0015] The improved washing and drying unit includes a frame three, with a guide wheel two installed on the top left side of the frame three, a guide wheel one installed on the top middle side of the frame three, a drying box arranged between the guide wheel one and the guide wheel two, and a cleaning device installed on the top of the frame three.
[0016] As a further description of the above technical solution:
[0017] The deep-tank nickel plating tank is provided with a depth of 350mm.
[0018] As a further description of the above technical solution:
[0019] Both the second wide-line conductive roller and the first wide-line conductive roller are provided with a wide-line conductive roller line width, and the line width of the wide-line conductive roller is 208mm.
[0020] As a further description of the above technical solution:
[0021] The outer side of the width of the conductive roller in the wide line area is the shape of the conductive roller groove in the wide line area. The shape of the conductive roller groove in the wide line area is formed by longitudinally arranging V-shaped grooves of equal width, equal depth, and equal spacing.
[0022] As a further description of the above technical solution:
[0023] Both the second guide wheel and the first guide wheel have a double V-groove guide wheel groove shape on their outer sides.
[0024] As a further description of the above technical solution:

[0026] This utility model has the following beneficial effects:
[0027] 1. In this utility model, in the improved sand plating unit, the solution containing corundum flows out from the high position of the overflow cylinder and enters the low position of the vortex sedimentation cylinder. The high-speed water flow impacts the water on one side of the cylinder to form a vortex. The corundum suspended in the water is thrown towards the cylinder wall and deposited at the bottom of the cylinder under the action of centrifugal force and gravity, thus achieving solid-liquid separation. The solution after thorough desanding flows into the sand plating return water tank through the high position of the vortex sedimentation cylinder, effectively protecting the centrifugal pump and filter element in the circulation system and enhancing the stability of continuous production of the equipment.
[0028] 2. In this invention, the improved nickel plating unit involves winding the diamond wire back and forth on the two wide-area conductive rollers up to 50 times, ensuring sufficient immersion time of the wire in the deep nickel plating bath. This results in an ideal plating thickness on the diamond wire surface, significantly improving its performance.
[0029] 3. In this utility model, the improved nickel plating unit has a large nickel plating return water tank area. After the nickel plating solution is recovered into the tank, the suspended diamond sand can be fully settled. The upper layer of nickel plating solution without sand flows from the high level of the nickel plating return water tank into the isolation tank and then participates in the circulation, thereby effectively protecting the filter element of the chemical agent filter.
[0030] 4. In this utility model, through the improved water washing and drying unit, the diamond wire reciprocates around two double V-groove guide wheels, which increases the thread count in the drying chamber by 40%, resulting in a good drying effect. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0042] Reference Figure 1 - Figure 8 An embodiment of this utility model is provided: a novel diamond wire sand plating machine, including a wire feeding control cabinet 1, a degreasing unit 2 installed on the left side of the wire feeding control cabinet 1, an acid pickling unit 3 installed on the left side of the degreasing unit 2, a pre-plating unit 4 arranged on the left side of the acid pickling unit 3, an improved sand plating unit 5 installed on the left side of the pre-plating unit 4, an improved nickel plating unit 6 installed on the left side of the improved sand plating unit 5, an improved water washing and drying unit 7 arranged on the left side of the improved nickel plating unit 6, and a wire take-up control cabinet 8 arranged on the left side of the improved water washing and drying unit 7.

Under the influence of gravity, the suspended diamond grit in the water settles completely to the bottom of the cylinder. Centrifugal pump 12 is used to lift the chemical solution in the plating return water tank 13 to the gravity cylinder 16. The plating return water tank 13 is used to collect the chemical solution after thorough sand removal in the cyclone sedimentation cylinder 15.

The drying box 28 is used to dry the diamond wire that has passed through, ending the entire production process.
[0045] Reference Figure 4 The improved nickel plating unit 6 includes a frame 2 32, a deep-groove nickel plating tank 18 is installed on the top of the frame 2 32, and wide-line area conductive rollers 2 19 and wide-line area conductive rollers 17 are respectively arranged on both sides of the deep-groove nickel plating tank 18. An isolation pool 21 is installed on the lower inner side of the frame 2 32, and a nickel plating return water pool 22 is installed on the lower inner side of the frame 2 32. Two chemical agent filters 2 20 are arranged on the left side of the frame 2 32.
[0046] Specifically, frame 2 32 is used to support components such as the deep-tank nickel plating tank 18, the wide-line area conductive roller 2 19, the wide-line area conductive roller 1 17, the isolation tank 21, the nickel plating return water tank 22, and the chemical filter 2 20, providing a support structure for the nickel plating operation. The deep-tank nickel plating tank 18 is used to hold the nickel plating solution, immersing the blank wire located between the two conductive rollers in it to complete the nickel plating. Its height matches the immersion height of the blank wire to achieve full nickel plating. The wide-line area conductive roller 1 17 and the wide-line area conductive roller 2 19 are used to make the blank wire reciprocate around the groove. Inside, the width and number of grooves ensure the number of turns the billet wire makes, providing conditions for nickel plating. Isolation tank 21 is used to receive the high-level, sand-free nickel plating solution from nickel plating return water tank 22, and supplies the solution to chemical filter 20 through a bottom pipe. Nickel plating return water tank 22 is used to recover the nickel plating solution after nickel plating, allowing it to settle and remove sand. The high-level, sand-free nickel plating solution after sand settling flows into isolation tank 21. Chemical filter 20 is used to filter and purify the nickel plating solution supplied to isolation tank 21, realizing the recycling of nickel plating solution.
[0047] Reference Figure 7 The improved washing and drying unit 7 includes a frame 33, a guide wheel 29 is installed on the top left side of the frame 33, a guide wheel 1 27 is installed on the top middle side of the frame 33, a drying box 28 is arranged between the guide wheel 1 27 and the guide wheel 29, and a cleaning device 26 is installed on the top of the frame 33.
[0048] Specifically, frame 33 supports components such as guide roller 1 27, guide roller 29, drying chamber 28, and cleaning device 26, providing a support structure for the washing and drying operation. Guide roller 1 27 and guide roller 29 are used to make the diamond wire reciprocate through the wire groove, so that the diamond wire between the two rollers passes through the drying chamber 28 multiple times to complete the thorough drying. The drying chamber 28 is used to dry the diamond wire that has passed through it, and the cleaning device 26 is used to wash away the residual chemical solution on the surface of the diamond wire.
[0049] Reference Figure 1 - Figure 8 The deep nickel plating tank 18 is provided with a deep nickel plating tank height 23, which is 350mm. The wide line area conductive roller 2 19 and the wide line area conductive roller 1 17 are both provided with a wide line area conductive roller line width 24, which is 208mm. The outer side of the wide line area conductive roller line width 24 is the wide line area conductive roller line groove shape 25, which is formed by V-shaped grooves of equal width, equal depth and equal spacing arranged longitudinally. The outer side of the guide wheel 2 29 and the guide wheel 1 27 are both double V-shaped guide wheel line groove shapes 30. The bottom of the wide line area conductive roller 2 19 is installed on the top of the frame 2 32.
[0050] Specifically, the deep-dip nickel plating tank 18 is set with a height of 23 and 350mm to provide sufficient immersion space for the wire blank, ensuring that the 50 turns of the wire blank winding between the first wide-line conductive roller 17 and the second wide-line conductive roller 19 are completely immersed in the nickel plating solution for thorough nickel plating. Both the second wide-line conductive roller 19 and the first wide-line conductive roller 17 are set with a width of 24 and 208mm to correspond to the arrangement of 50 grooves, thus ensuring that the wire blank winds 50 times between the two conductive rollers to meet the requirements of the nickel plating process. A groove shape 25 is provided on the outer side of the width 24 of the wide-line conductive roller to guide and restrict the winding of the wire blank. The path allows the wire blank to travel between the first conductive roller 17 and the second conductive roller 19 in a specified manner and number of turns, ensuring full contact between the wire blank and the nickel plating solution while guaranteeing the stability and uniformity of conductivity. The outer sides of the second conductive roller 29 and the first conductive roller 27 are both double V-groove conductive roller grooves 30, used to guide the diamond wire to travel back and forth between the two rollers along a specific path, so that the diamond wire passes through the drying chamber 28 5 times to achieve thorough drying. At the same time, the double V-groove design helps to position and guide the diamond wire, preventing the diamond wire from deviating or shaking during operation. The bottom of the second conductive roller 19 is mounted on the top of the second frame 32 to fix the second conductive roller 19 in a suitable position.
[0051] Working principle: After the billet line is released from the line release control cabinet 1, it first enters the degreasing unit 2 for alkaline washing and degreasing, then passes through the pickling unit 3 for water washing and pickling, and finally enters the pre-plating unit 4 for water washing and pre-plating nickel treatment. At this point, the pre-treatment process of the billet line is completed.
[0052] The pre-treated wire blank is introduced into the improved sand plating unit 5. The wire blank passes through the sand plating cylinder 10 from bottom to top, while the chemical solution cylinder 9 injects a mixture of diamond grit and chemical solution into it, so that the wire blank completes the sand plating under the action of electrolysis.
[0053] After the chemical solution in the sand-plating cylinder 10 overflows, it flows into the overflow cylinder 11 for preliminary sedimentation. The chemical solution at the higher level of the overflow cylinder 11 enters the lower level of the vortex sedimentation cylinder 15 through a pipe. Because the inlet pipe of the vortex sedimentation cylinder 15 is tangent to its circular cylinder wall (i.e., the outer edge of the inlet pipe is horizontally tangent to the cross-section of the inner wall of the cylinder), the water flow impacts the edge of the water in the cylinder, forming a vortex. The suspended diamond grit in the water is thrown towards the cylinder wall under the action of centrifugal force and gravity, and completely settles to the bottom of the cylinder. The chemical solution after thorough sand removal flows into the sand-plating return water tank 13, and then rises to the gravity cylinder 16 by the action of the centrifugal pump 12, replenishing the sand-plating cylinder 10 as needed, thus realizing the circulation of the chemical solution. The chemical reagent filter 14 and the sand-plating return water tank 13 separately circulate the chemical solution for purification.
[0054] The sand-plated wire blank is introduced into the improved nickel plating unit 6. The wire blank reciprocates within the grooves of the wide-line conductive roller 17 and the wide-line conductive roller 29 (both conductive roller groove structures adopt the wide-line conductive roller groove shape 25), making 50 turns. The wire blank located between the two conductive rollers is immersed in the nickel plating solution in the deep-tank nickel plating tank 18, and nickel plating is completed under the action of electrolysis.
[0055] The width of the conductive roller 17 and the conductive roller 2 in the wide-line area mentioned above is 208mm (e.g., the width of the conductive roller in the wide-line area is 24mm). This size corresponds to 50 grooves, thus ensuring the number of turns. The height of the deep nickel plating tank 23 is 350mm, which matches the immersion height of 50 turns of blank wire, achieving sufficient nickel plating.
[0056] The aforementioned nickel plating solution is recycled to the nickel plating return water tank 22 for settling and sand removal. The high-level, sand-free nickel plating solution flows into the isolation tank 21. The isolation tank 21 supplies the nickel plating solution to the chemical agent filter 20 through the bottom pipe for further recycling.
[0057] After being drawn from the improved nickel plating unit 6, the blank wire has been transformed into a complete diamond wire structure. However, residual chemicals remain on its surface, requiring further treatment in the improved washing and drying unit 7. The diamond wire first enters the cleaning device 26 to remove the residual chemicals, and then repeatedly winds through the grooves of the double V-groove guide wheel 1 27 and the double V-groove guide wheel 29 (both wheels use a double V-groove guide wheel groove shape 30). The number of turns is 2, allowing the diamond wire between the two wheels to pass through the drying chamber 28 5 times, ensuring thorough drying.
[0058] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
