With the booming development of the building decoration industry, the demand for more refined and efficient stone processing is increasing. Currently, there are various stone polishing equipment on the market, but for portable handheld polishing equipment, there are still many problems to be solved.
[0003] From the perspective of ease of operation, existing handheld polishing equipment has a relatively simple grip design. When used for a long time, the lack of adjustable auxiliary grip points can easily lead to hand fatigue. It is also difficult to flexibly adjust the grip according to different polishing postures and habits. When polishing large areas of stone chamfers, it is difficult to stably control the polishing direction when holding the processing handle with one hand. Most existing handheld polishing equipment lacks a reasonable wire management structure, and the wire is often left lying around after use. At the same time, many existing handheld polishing equipment are not equipped with an effective dust collection device. Therefore, this utility model provides a portable stone edge chamfering polishing machine. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a portable stone edge beveling and polishing machine. From an operational convenience perspective, traditional handheld polishing equipment suffers from a simple grip design. Prolonged use without adjustable grip points easily leads to hand fatigue, and it's difficult to flexibly adjust the grip according to different polishing postures and habits. When beveling large areas of stone, holding the handle with one hand makes it difficult to stably control the polishing direction. Furthermore, most existing handheld polishing equipment lacks a reasonable cable management structure, resulting in cables being left haphazardly after use. Additionally, many existing handheld polishing devices are not equipped with effective dust collection devices.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a portable stone edge beveling and polishing machine, comprising a polishing machine body, wherein the polishing machine body is provided with a user mechanism for handheld stone edge beveling and polishing, the user mechanism comprising:
[0006] The handheld assembly includes a processing handle fixed to the upper end of the grinding machine body, the outer wall of the processing handle is covered with a sponge sleeve, a carrying handle is fixed to the end of the grinding machine body, an adjusting slide rail is fixed to the outer wall of the grinding machine body, and an auxiliary handle connected by a locking assembly is provided inside the adjusting slide rail.
[0007] The collection assembly includes a collection shell fixed to the lower end of the main body of the grinder, a bolt plug provided at the lower end of the collection shell, a winding block fixed to one side wall of the main body of the grinder, slot blocks evenly fixed at the upper and lower ends of the winding block, and a rubber ring fixed at the upper end of the slot block.
[0008] Preferably, the handles are configured in two sets, and the two sets of handles are in a U-shaped structure.
[0009] Preferably, the locking assembly includes an annular groove inside the adjusting slide rail, a slider is slidably connected inside the annular groove, the auxiliary grip is fixedly connected to one side wall of the slider, and threaded holes are evenly provided on the side wall of the adjusting slide rail, with locking bolts threaded inside the threaded holes and connected to the slider.
[0010] Preferably, the end of the grinding machine body is provided with a power supply wire, and the end of the power supply wire is connected to a plug.
[0011] Preferably, the side wall of the winding block is provided with a through hole groove, and a connecting rope is fixed to one side of the through hole groove on the side wall of the winding block, and a rubber sleeve is fixed to the end of the connecting rope.
[0012] Preferably, the front end of the grinding machine body is provided with a grinding disc for chamfering, and a protective shell is fixed to the outer side of the grinding disc at the lower end of the grinding machine body. A conduit is connected through the lower end of the protective shell, and the end of the conduit is connected to the side wall of the collection shell.
[0013] Beneficial effects
[0014] This invention provides a portable stone edge beveling and grinding machine. Compared with the prior art, it has the following advantages:
[0015] Firstly, the operator can adjust the position of the auxiliary handle according to their own grinding habits. First, loosen the locking bolt, so that the slider slides along the annular groove in the adjusting slide rail, and move the auxiliary handle to a comfortable position, such as the left, right or diagonally below the main body of the grinder. Then, tighten the locking bolt into the corresponding threaded hole until it fits tightly with the slider, and fix the auxiliary handle. The operator holds the processing handle with one hand as the main grip point to control the grinding direction, and holds the auxiliary handle with the other hand as an auxiliary support point to stabilize the grinding force. After starting the equipment, the operator pushes the main body of the grinder with both hands to make the front grinding disc fit against the edge of the stone for chamfering. During the process, the hand is in direct contact with the sponge sleeve, reducing the pressure of the handle on the palm and avoiding instability when operating with one hand. The overall operation is simple and allows the operator to process more stably.
[0016] Secondly, the operator of this utility model arranges the wire from the end of the grinding machine body towards the winding block, inserting the wire segment by segment into the slot block. The groove structure of the slot block restricts the displacement of the wire. At the same time, the rubber ring is pressed. The rubber ring is elastic and tightly wraps the wire after being inserted, preventing the wire from falling out of the slot block. The operation is repeated until the wire is completely wrapped around the winding block. Then, the plug at the end of the wire is passed through the through hole groove on the side wall of the winding block, and the rubber sleeve at the end of the connecting rope is put on the plug. The inner diameter of the rubber sleeve is slightly smaller than the outer diameter of the plug. The elastic contraction tightly locks the plug, preventing the plug from falling out of the through hole groove and preventing the metal contacts of the plug from being exposed. This facilitates the storage of the wire and makes the equipment more convenient to carry.
[0017] Thirdly, during processing, the micro pump at the top of the grinding machine body and the collection shell is activated. The operation of the micro pump creates a negative pressure inside the collection shell. When the grinding disc bevels the edge of the stone, the dust generated is blocked by the protective shell, preventing the dust from spreading to the surroundings. Under the action of negative pressure, the dust flows down along the inner wall of the protective shell and enters the collection shell through the conduit, completing the dust collection. When the dust accumulates to a certain amount inside the collection shell, the equipment is turned off, and the bolt plug at the bottom is unscrewed, allowing the collected dust to be discharged from the bottom of the collection shell, thus solving the problem of the lack of dust collection in existing handheld grinding equipment.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.
[0024] Please see Figure 1-4 This utility model provides a technical solution: a portable stone edge beveling and polishing machine, including a polishing machine body 1, and a using mechanism for handheld stone edge beveling and polishing equipment provided on the polishing machine body 1, the using mechanism including:
[0025] The handheld component includes a processing handle 3 fixed to the upper end of the grinding machine body 1, a sponge sleeve 301 covering the outer wall of the processing handle 3, a carrying handle 302 fixed to the end of the grinding machine body 1, an adjusting slide rail 5 fixed to the outer wall of the grinding machine body 1, and an auxiliary handle 504 connected by a locking component inside the adjusting slide rail 5.
[0026] The collection assembly includes a collection shell 603 fixed to the lower end of the grinding machine body 1, a bolt plug 604 provided at the lower end of the collection shell 603, a winding block 4 fixed to one side wall of the grinding machine body 1, a slot block 401 evenly fixed to the upper and lower ends of the winding block 4, and a rubber ring 402 fixed to the upper end of the slot block 401.
[0027] In a preferred embodiment, the handles 302 are configured in two sets, and the two sets of handles 302 are U-shaped. When the equipment needs to be moved or transported, the operator can put both hands into the two sets of U-shaped handles 302 respectively and carry the grinding machine body 1 by hand, which is convenient to operate.
[0028] In a preferred embodiment, the locking assembly includes an annular groove 501 inside the adjusting slide rail 5, a slider 503 slidably connected inside the annular groove 501, an auxiliary grip 504 fixedly connected to one side wall of the slider 503, threaded holes 502 evenly provided on the side wall of the adjusting slide rail 5, a locking bolt 505 threadedly connected inside the threaded hole 502 and connected to the slider 503, the processing grip 3 is located above the main body 1 of the grinder, and the device is held by hand for operation, while the auxiliary grip 504 is used for holding with the other hand.
[0029] Specifically, the operator adjusts the position of the auxiliary handle 504 according to their own grinding habits. First, loosen the locking bolt 505 so that the slider 503 slides along the annular groove 501 in the adjusting slide rail 5, moving the auxiliary handle 504 to a comfortable position, such as the left, right, or lower side of the grinding machine body 1. Then, screw the locking bolt 505 into the corresponding threaded hole 502 until it fits tightly with the slider 503, fixing the auxiliary handle 504. The operator holds the processing handle 3 with one hand as the main grip point to control the grinding direction, and holds the auxiliary handle 504 with the other hand as an auxiliary support point to stabilize the grinding force. After starting the equipment, the operator pushes the grinding machine body 1 with both hands to make the front grinding disc 6 fit against the edge of the stone for chamfering. During the process, the hand is in direct contact with the sponge sleeve 301, reducing the pressure of the handle on the palm and avoiding instability when operating with one hand. The overall operation is simple and allows the operator to process more stably.
[0030] In a preferred embodiment, the end of the grinding machine body 1 is provided with a power supply wire 2, and the end of the wire 2 is connected to a plug 201. The side wall of the winding block 4 is provided with a through hole groove 403. A connecting rope 404 is fixed to one side of the through hole groove 403 on the side wall of the winding block 4. A rubber sleeve 405 is fixed to the end of the connecting rope 404. The wire 2 can be wound inside the slot block 401. The rubber ring 402 at the upper end of the slot block 401 is used to limit the wire 2 inside the slot block 401 to prevent it from falling off. After the wire 2 is wound, the plug 201 is inserted into the through hole groove 403. The plug 201 is tightly locked by the rubber sleeve 405 after it has passed through, which protects the plug 201 and prevents it from falling off in the through hole groove 403, thereby storing the wire 2.
[0031] Specifically, after the equipment is used, the operator arranges the wire 2 from the end of the grinding machine body 1 towards the winding block 4, inserting the wire 2 segment by segment into the slot block 401. The groove structure of the slot block 401 restricts the displacement of the wire 2. At the same time, the rubber ring 402 is pressed. The rubber ring 402 is elastic and tightly wraps the wire 2 after being inserted, preventing the wire 2 from falling out of the slot block 401. The operation is repeated until the wire 2 is completely wrapped around the winding block 4. Then, the plug 201 at the end of the wire 2 is passed through the through hole groove 403 on the side wall of the winding block 4. The rubber sleeve 405 at the end of the connecting rope 404 is then put on the plug 201. The inner diameter of the rubber sleeve 405 is slightly smaller than the outer diameter of the plug 201. Through elastic contraction, the plug 201 is tightly locked, which not only prevents the plug 201 from falling out of the through hole groove 403, but also prevents the metal contacts of the plug 201 from being exposed. This makes it easier to store the wire 2 and makes the equipment more convenient to carry.
[0032] In a preferred embodiment, a grinding disc 6 for chamfering is provided at the front end of the grinding machine body 1. A protective shell 601 is fixed to the outer side of the grinding disc 6 at the lower end of the grinding machine body 1. A conduit 602 is connected through the lower end of the protective shell 601. The end of the conduit 602 is connected to the side wall of the collection shell 603. A micro pump for generating negative pressure is provided at the upper end of the collection shell 603. During processing, the micro pump at the upper end of the grinding machine body 1 and the collection shell 603 is activated. The operation of the micro pump causes the pressure inside the collection shell 603 to be negatively affected. When a negative pressure is formed, the dust generated when the grinding disc 6 bevels the edge of the stone is blocked by the protective shell 601, preventing the dust from spreading to the surroundings. Under the action of negative pressure, the dust flows down along the inner wall of the protective shell 601 and enters the collection shell 603 through the conduit 602 to complete the dust collection. When the dust accumulates to a certain amount in the collection shell 603, the equipment is turned off, and the bolt plug 604 at the lower end is unscrewed to allow the collected dust to be discharged from the bottom of the collection shell 603, thus solving the problem of the lack of dust collection in existing handheld grinding equipment.
[0033] The micro pump model selected above can be the Kamor KDP25.
[0034] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0035] When using this portable stone edge beveling and grinding machine, the first step is to move the equipment. With the help of the two sets of U-shaped handles 302 fixed to the end of the grinding machine body 1, the operator can put their hands into the two sets of handles 302 respectively and carry the grinding machine body 1 by hand.
[0036] Then, adjust the grip structure according to your own grinding habits. First, loosen the locking bolt 505 in the threaded hole 502 on the side wall of the adjustment slide rail 5, so that the slider 503 in the annular groove 501 drives the auxiliary grip 504 to slide along the adjustment slide rail 5 to a comfortable position, such as the left, right or diagonally below the main body of the grinder 1. Then, screw the locking bolt 505 back into the corresponding threaded hole 502 and fit it tightly with the slider 503 to fix the auxiliary grip 504.
[0037] Next, the equipment is started for chamfering: the operator holds the processing handle 3 with a sponge sleeve 301 on the upper end of the grinding machine body 1 with one hand and the auxiliary handle 504 with the other hand. Simultaneously, the micro pump on the upper end of the grinding machine body 1 and the collection shell 603 is started. The micro pump creates a negative pressure inside the collection shell 603. When the grinding disc 6 at the front end of the grinding machine body 1 chamfers the edge of the stone, the dust generated is blocked by the protective shell 601 on the outside of the grinding disc 6. Under the action of negative pressure, it flows down along the inner wall of the protective shell 601 and enters the collection shell 603 at the lower end of the grinding machine body 1 through the conduit 602 to complete the dust collection.
[0038] After processing, first turn off the equipment. If a lot of dust has accumulated inside the outer casing 603, unscrew the bolt plug 604 at the lower end to discharge the dust. Then, store the wires. Insert the wire 2 at the end of the grinding machine body 1 into the slots 401 at the upper and lower ends of the winding block 4. The rubber ring 402 at the upper end of the slot 401 will limit the wires and prevent them from falling off. After the wire 2 is completely wrapped around the winding block 4, pass the plug 201 at the end of the wire 2 through the through hole slot 403 on the side wall of the winding block 4. Then, use the rubber sleeve 405 at the end of the connecting rope 404 to cover the plug 201. This will prevent the plug 201 from falling off and protect its metal contacts, thus completing the entire process of using and storing the equipment.
