Description

Technical Field

[0001] This utility model belongs to the field of blade grinding technology, specifically relating to a magnetic separator for blade grinding. Background Technology

[0002] Pruning machines are suitable for professional pruning in landscaping applications such as tea plantation trimming, park and garden hedge trimming, and roadside pruning. The machines are equipped with blades for trimming vegetation. During production, the pruning machine blades are sharpened to remove the oxide layer on the blade surface, improving sharpness and extending their lifespan. The blade surface temperature is high during sharpening, so coolant is continuously sprayed onto the blade surface to inhibit thermal deformation, maintain the original metallic color, and prevent "burning" of the blade surface.

[0003] In the process of grinding blades in large quantities, a large amount of coolant is required. In order to save costs, the coolant after grinding needs to be recycled for secondary and tertiary use. However, the iron filings mixed in the coolant during the blade grinding process will scratch the blade surface and damage the surface finish when the blade is used again. Therefore, there is an urgent need for a device to remove the iron filings contained in the coolant, so as to realize the secondary use of the coolant. Utility Model Content

[0029] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0030] like Figure 1-4 The diagram shows a schematic of the magnetic separator for blade sharpening according to this invention. It is commonly used in the field of pruning machine blade sharpening to adsorb iron filings and impurities in coolant, improving the purity of the coolant for reuse. The magnetic separator includes a separation chamber, an adsorption component, and a pressing component. The coolant after pruning the machine blades is passed into the separation chamber. Under the action of magnetic force, the adsorption component adsorbs iron filings from the coolant onto its surface. The pressing component works in conjunction with the adsorption component to squeeze out the coolant mixed with the iron filings. Finally, the iron filings on the surface of the adsorption component are scraped off.

[0031] The separation box includes a bottom plate 1, a first upright plate 2, a water inlet 3, a second upright plate 4, a support plate 5, a folding plate 6, a first side plate 7, and a second side plate 8. The bottom plate 1, the first upright plate 2, the second upright plate 4, the support plate 5, the folding plate 6, the first side plate 7, and the second side plate 8 are all stainless steel metal plates, which are welded together to form a hollow box structure, thus forming the separation box structure.

[0032] The first upright plate 2 and the second upright plate 4 are vertically fixed to the top of the base plate 1 and are arranged opposite each other. The first side plate 7 and the second side plate 8 are vertically fixed to the top of the base plate 1 and are arranged opposite each other. (Specifically, the first upright plate 2 and the second upright plate 4 are located at the two sets of short sides of the base plate 1, and the first side plate 7 and the second side plate 8 are located at the two sets of long sides of the base plate 1. The connection between the two adjacent plates is fixed together by welding, thereby forming a hollow box structure. Coolant is injected into the separation box to prevent coolant from seeping out from the gaps.)

[0033] The water inlet 3 is opened on the first vertical plate 2 and passes through the first vertical plate 2. The coolant after the pruning machine blades are ground is introduced into the separation box through the pipe (specifically, one end of the pipe is connected to the coolant collection box after the pruning machine blades are ground, and the other end of the pipe passes through the water inlet 3 of the first vertical plate 2, and the coolant in the coolant collection box flows into the separation box through the pipe).

[0034] The support plate 5 is integrally connected to the top of the second vertical plate 4 and is set at an angle, such as... Figure 3 , 4 As shown, the support plate 5 extends inclined towards the side closer to the first vertical plate 2. When the chip removal plate 9 is fixed to the top of the support plate 5, it is also inclined due to the inclined setting of the support plate 5, which facilitates the discharge of iron chips. The folding plate 6 is integrally connected to the other side of the support plate 5 and is inclined towards the side closer to the bottom plate 1. The folding plate 6 is used to improve the structural strength of the support plate 5 and prevent the support plate 5 from deforming during chip removal.

[0035] A liquid-blocking mechanism is installed on one side of the separator to buffer the incoming coolant and prevent it from directly impacting the adsorption cylinder 34, thus avoiding coolant splashing or damage to the adsorption cylinder 34. Figure 2 , 4 As shown, the liquid-blocking mechanism includes a first fixed plate 12, an extension plate 13, a second fixed plate 14, and a second baffle 15. The first fixed plate 12 is fixed to the top of the inner side of the first upright plate 2 by welding, and the first fixed plate 12 is perpendicular to the first upright plate 2. The extension plate 13 is integrally connected to the side of the first fixed plate 12 away from the first upright plate 2, and extends downward to contact the guide plate 16.

[0036] like Figure 2 As shown, the corner plate structure composed of the first fixed plate 12 and the extension plate 13 consists of two sets, located on both sides of the first upright plate 2, with a through groove between the two sets of corner plates for coolant flow. By setting the corner plate structure, coolant is ensured to flow from the through groove between the two sets of corner plates to the adsorption cylinder 34. When adsorbing iron filings, the adsorption cylinder 34 ensures that the iron filings accumulate in the middle part of the adsorption cylinder 34, facilitating subsequent discharge of the iron filings. This prevents iron filings from accumulating at both ends of the adsorption cylinder 34, and avoids them being pressed outwards and falling to the ground from both ends when squeezed by the pressure roller 27.

[0037] The second fixing plate 14 is fixed to the top of the first fixing plate 12 by screws. The second baffle 15 is integrally connected to the side of the second fixing plate 14 away from the first upright plate 2 and extends downward to partially block the through groove between the two sets of corner plate structures. Figure 2 , 3 As shown, after the coolant enters the separator from the water inlet 3, the second baffle 15 will buffer the coolant to a certain extent, preventing the coolant from directly impacting the adsorption cylinder 34.

[0038] like Figure 2-4 As shown, the liquid guiding mechanism includes a guide plate 16, a lower arc-shaped plate 17, a connecting plate 18, and an upper arc-shaped plate 19. The guide plate 16 is fixed to the top of the base plate 1 by welding. Figure 2-4 As shown, the guide plate 16 is inclined and forms an acute angle with the bottom plate 1. When the coolant enters the separator, it will gradually enter the lower arc plate 17 for adsorption under the guiding action of the guide plate 16.

[0039] The lower arc-shaped plate 17 is integrally connected to the top of the guide plate 16 with its arc center facing upwards. The connecting plate 18 is integrally connected to the side of the lower arc-shaped plate 17 away from the guide plate 16. The upper arc-shaped plate 19 is integrally connected to the top of the connecting plate 18 with its arc center facing upwards. Figure 2 As shown, a liquid guiding groove is formed between the two upper arc-shaped plates 19. The coolant enters the liquid guiding groove along the guide plate 16 and then exits from the other side of the liquid guiding groove. During this process, the rotating adsorption cylinder 34 adsorbs iron filings in the coolant under the action of magnetic force, thereby improving the purity of the coolant and enabling it to be recycled.

[0040] By setting two sets of upper arc-shaped plates 19 to block the two ends of the adsorption cylinder 34, the adsorption cylinder 34 ensures that the iron filings gather in the middle part of the adsorption cylinder 34 when adsorbing iron filings, which facilitates the subsequent discharge of iron filings. This prevents the iron filings from gathering at both ends of the adsorption cylinder 34 and from being pressed outwards and falling off from both ends when squeezed by the pressure roller 27.

[0041] The chip removal mechanism includes a chip removal plate 9, a first baffle 10, and a transition plate 11. The chip removal plate 9 is fixed to the top of the support plate 5 by screws. Since the support plate 5 is inclined, the chip removal plate 9 is also inclined to facilitate the discharge of the absorbed iron filings. There are two first baffles 10, which are integrally connected to the two sides of the top of the chip removal plate 9 and are arranged opposite each other. During chip removal, they block the iron filings and prevent them from falling to the ground from the sides of the chip removal plate 9.

[0042] A collection box is placed at the lowest point of the chip conveyor plate 9 to collect the separated iron filings. The transition plate 11 is adjustablely installed on the top of the chip conveyor plate 9 (specifically, the transition plate 11 has a through hole, and the corresponding position of the chip conveyor plate 9 has a waist-shaped groove, and the length direction of the waist-shaped groove is parallel to the length direction of the chip conveyor plate 9. The fastening bolt is passed through the through hole and the waist-shaped groove, and the other end is fitted with a fastening nut to complete the installation of the transition plate 11).

[0043] By adjusting the position of the transition plate 11, the gap between the transition plate 11 and the adsorption cylinder 34 can be adjusted, making the installation more flexible, reducing the difficulty of processing, and avoiding installation failures due to misalignment of holes during processing, which could lead to excessive friction due to overly tight contact between the transition plate 11 and the adsorption cylinder 34.

[0044] The extrusion assembly includes a first mounting plate 20, a screw 21, a pressure roller shaft 22, a contact surface 23, an upper pressure plate 24, a lower pressure plate 25, a spring 26, a pressure roller 27, a second mounting plate 28, and a third mounting plate 29. Figure 1 , 5 As shown, the first mounting plate 20 is fixed to the two side walls of the separation box by welding. Specifically, the first mounting plate 20 is fixed to the outside of the first side plate 7 and the second side plate 8 and is set at an angle. When the pressure roller 27 is installed later, it is ensured that the pressure roller 27 presses on the adsorption cylinder 34 from the angled direction, so as to squeeze the iron filings on the outer peripheral surface of the adsorption cylinder 34 together with the adsorption cylinder 34 to discharge the coolant attached to the iron filings.

[0045] like Figure 5 As shown, a through threaded hole is provided on the first mounting plate 20, and the screw 21 is screwed into the threaded hole on the first mounting plate 20 (the screw 21 includes a shank and a head, and the shank of the screw 21 is screwed into the threaded hole). Through holes are provided at both ends of the pressure roller shaft 22, and the diameter of the through holes is larger than the outer diameter of the screw 21. Therefore, the screw 21 passes through the through holes at both ends of the pressure roller shaft 22 and is screwed into the threaded hole of the first mounting plate 20. The pressure roller 27 is rotatably mounted on the pressure roller shaft 22 and abuts against the outside of the adsorption cylinder 34 (specifically, bearings are installed at both ends of the pressure roller shaft 22 by interference fit, and the hollow pressure roller 27 is installed on the bearings by interference fit, ensuring that the pressure roller 27 can rotate on the pressure roller shaft 22 under the action of the bearings).

[0046] The upper pressure plate 24, the lower pressure plate 25, and the spring 26 are fitted onto the screw 21, with the spring 26 positioned between the upper pressure plate 24 and the lower pressure plate 25. The upper pressure plate 24 abuts against the head of the screw 21, and the lower pressure plate 25 abuts against the side of the pressure roller shaft 22 away from the first mounting plate 20. A contact surface 23 is formed on the side of the pressure roller shaft 22 away from the first mounting plate 20, and the side of the spring 26 away from the upper pressure plate 24 abuts against the contact surface 23. By setting the contact surface 23, the contact area between the spring 26 and the pressure roller shaft 22 is increased, thereby improving the stability of the spring 26.

[0047] By rotating the screw 21, the spring 26 is gradually compressed. Under the force of the spring 26, the spring 26 pushes against the pressure roller shaft 22, thereby pressing the pressure roller 27 against one side of the adsorption cylinder 34. When the adsorption cylinder 34 rotates, the friction force drives the pressure roller 27 to rotate synchronously, together with the adsorption cylinder 34, squeezing the iron filings on the outer circumference of the adsorption cylinder 34 to discharge the coolant attached to the iron filings. By adjusting the position of the screw 21, the pressure between the pressure roller 27 and the adsorption cylinder 34 can be adjusted, thereby improving the drainage effect.

[0048] like Figure 1 , 6As shown in Figure 7, the adsorption assembly includes a second mounting plate 28, a third mounting plate 29, a servo motor 30, a bearing seat 31, a left end cover 32, a right end cover 33, an adsorption cylinder 34, a mounting shaft 35, a bearing 36, a mounting disc 37, a first mounting piece 38, a second mounting piece 39, a first magnetic block 40, a second magnetic block 41, and a partition plate 42. There are two second mounting plates 28, which are fixed to the first side plate 7 of the separation box by welding. The third mounting plate 29 is fixed to the side of the second mounting plate 28 away from the separation box by welding (the second mounting plate 28 and the third mounting plate 29 form a "[" structure, and the opening side of the "[" structure faces the first side plate 7).

[0049] The bearing housing 31 is fixed to the outside of the first side plate 7 of the separation box by screws, and the bearing housing 31 is located between the two second mounting plates 28. The housing of the servo motor 30 is fixed to the third mounting plate 29 by screws. The output shaft of the servo motor 30 passes through the bearing housing 31 and is connected to the left end cover 32. The servo motor 30 drives the left end cover 32 to rotate (specifically, the output shaft of the servo motor 30 is connected to the left end cover 32 by a key connection).

[0050] The adsorption cylinder 34 is a hollow cylinder. One side of the adsorption cylinder 34 is fitted onto the left end cap 32, and the other side of the adsorption cylinder 34 is fitted onto the right end cap 33. The adsorption cylinder 34 is then fixed together with the left end cap 32 and the right end cap 33 by screws. When the servo motor 30 rotates, it drives the left end cap 32, the adsorption cylinder 34, and the right end cap 33 to rotate synchronously.

[0051] One end of the mounting shaft 35 is fixed to the inside of the second side plate 8 by welding, and the other end of the mounting shaft 35 passes through the right end cover 33 and is placed inside the adsorption cylinder 34 (a bearing 36 is provided between the mounting shaft 35 and the right end cover 33). When the servo motor 30 drives the left end cover 32, the adsorption cylinder 34 and the right end cover 33 to rotate, the mounting shaft 35 will not rotate under the action of the bearing 36. The mounting shaft 35 is used to install the magnetic adsorption unit, and at the same time, the mounting shaft 35 is used to assist in supporting the right end cover 33 to prevent the adsorption cylinder 34 from tilting.

[0052] like Figure 6 As shown, there are at least two sets of mounting discs 37, which are spaced apart and mounted on the mounting shaft 35, and the mounting discs 37 and the mounting shaft 35 are fixed together by welding. Figure 7 As shown, the top of the mounting plate 37 has a horizontal cross-section. After the first magnetic block 40 and the second magnetic block 41 are installed, a non-magnetic area is formed on one side of the top of the mounting plate 37, facilitating the removal of iron filings. The first mounting piece 38 is annular and is fixed to the outside of the mounting plate 37 by welding. Figure 6 The rotation direction of the mounting plate 37 is counterclockwise.

[0053] The second mounting plate 39 is fixed to the top of the mounting plate 37 with a horizontal cross section by welding. The partition plate 42 is vertically fixed to one side of the second mounting plate 39 by welding, and the partition plate 42 bisects the mounting plate 37 in the vertical direction (i.e. the diameter of the partition plate 42 coincides with that of the mounting plate 37).

[0054] The first magnetic block 40 is fastened with screws around the outside of the first mounting plate 38, and the second magnetic block 41 is fastened with screws on the top of the second mounting plate 39. When the servo motor 30 drives the adsorption cylinder 34 to rotate, the iron filings in the coolant are adsorbed onto the outer wall of the adsorption cylinder 34 under the action of the first magnetic block 40 and the second magnetic block 41. When the adsorption cylinder 34 rotates past the highest position (i.e., the position of the partition plate 42), since the mounting plate 37 is in the non-magnetic area, the iron filings on the surface of the adsorption cylinder 34 will fall onto the inclined transition plate 11. At the same time, the inclined transition plate 11 also has a certain scraping effect, effectively removing the iron filings on the surface of the adsorption cylinder 34.

[0055] like Figure 7 As shown, the left side of the partition 42 is a non-magnetic area, and the right side of the partition 42 is a magnetic area. The partition 42 is used to isolate the magnetic area and the non-magnetic area, so as to prevent the second magnetic block 41 from interfering with the chip removal.

[0056] The working principle of this magnetic separator for blade grinding is as follows:

[0057] The servo motor 30 drives the adsorption cylinder 34 to make a circular motion, while the mounting plate 37 remains stationary. Iron filings are adsorbed on the adsorption cylinder 34 at the position corresponding to the magnetic area. When the iron filings on the adsorption cylinder 34 move to the non-magnetic area, they lose their magnetic effect. The transition plate 11 easily scrapes off the impurities on the adsorption cylinder 34, and the impurities are discharged through the chip removal plate 9. At the same time, the pressure roller 27 is set to squeeze the iron filings adsorbed on the adsorption cylinder 34, squeezing out the moisture in the iron filings, so as to avoid the moisture content in the separated iron filings being too high and increasing the subsequent processing steps.

[0058] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
