Abstract
Description
Technical Field
[0001] This application relates to the field of grinding device technology, specifically to a grinding bottle and its automatic opening and closing system. Background Technology
[0002] In a sample grinding production line, grinding rods and samples need to be loaded into grinding bottles and then placed on a grinding machine for rotation, whereby the grinding rods grind the samples during rotation. To facilitate the insertion and removal of grinding rods and samples, the grinding bottles need to have detachable bodies and caps; to improve efficiency, appropriate opening and closing devices are needed to automatically open and close the grinding bottles.
[0003] Existing grinding bottles use threads and a pin to secure the cap. This method requires manual insertion of the fastener into the bottle's mounting slot, followed by securing the cap with a threaded pin. Automating this process is difficult, and controlling the tightening degree is often challenging. Insufficient tightening results in a poor seal between the bottle and cap, potentially leading to leakage during grinding. Conversely, excessive tightening increases the difficulty of unscrewing and can damage the grinding bottle.
[0004] In view of this, it is necessary to design an improved grinding bottle and its automatic opening and closing system to solve the above problems. Summary of the Invention
[0005] In view of the technical problems existing in the background art, this application provides a grinding bottle and its automatic opening and closing system, which can conveniently and reliably realize the automatic opening and closing of the grinding bottle.
[0006] In a first aspect, embodiments of this application provide a grinding bottle, including a bottle body and a bottle cap;
[0007] The bottle body has a receiving cavity for accommodating the grinding rod and the sample, and the inner wall of the bottle body is provided with a mounting groove;
[0008] The bottle cap includes a cap body, a mounting rod, and a first telescopic mechanism connecting the cap body and the mounting rod; the telescopic direction of the first telescopic mechanism is perpendicular to the cap body;
[0009] When the mounting rod and the mounting groove are aligned in the height direction, the end of the mounting rod can be screwed into or out of the mounting groove, and the first telescopic mechanism is used to apply an upward force to the mounting rod.
[0010] In the technical solution of this application embodiment, the bottle body and the bottle cap are engaged via a mounting groove and a mounting rod. By pressing the mounting rod to align it with the mounting groove, the end of the mounting rod can be rotated to screw into or out of the mounting groove, thus opening or closing the grinding bottle. Based on the grinding bottle provided in this application embodiment, opening and closing the grinding bottle only requires two steps: pressing and rotating. This is not only simple and efficient, but also prevents loosening after simple rotation, effectively avoiding material leakage when the closed grinding bottle rotates on the grinding machine.
[0011] In some embodiments, the mounting rod includes a mounting portion, a sleeve, and a mounting pin; the mounting portion is connected to the first telescopic mechanism, the sleeve is symmetrically disposed on both sides of the mounting portion, and the mounting pin is disposed at one end of the sleeve away from the mounting portion; a second telescopic mechanism is provided between the sleeve and the mounting pin for extending and retracting the mounting pin along the axial direction of the sleeve.
[0012] In this embodiment, the mounting pin can extend and retract along the axial direction of the sleeve so that the mounting pin engages with the mounting groove.
[0013] In some embodiments, the second telescopic mechanism includes a second spring connecting the sleeve and the mounting pin, a guide pin disposed in the sleeve, and a guide hole disposed in the mounting pin; the guide pin is disposed radially along the sleeve, the guide hole is disposed axially along the sleeve, and the guide pin is located within the guide hole.
[0014] In this embodiment, the second spring can drive the mounting pin to extend and retract, and the guide pin and guide hole can control the extension and retraction direction of the mounting pin, so that the mounting pin can stably extend and retract along the axial direction of the sleeve.
[0015] In some embodiments, the end of the mounting pin away from the sleeve has a bevel facing the cover.
[0016] In this embodiment, by setting a corresponding inclined surface in the mounting pin, when placing the bottle cap, the inner wall edge of the bottle can be used to squeeze the inclined surface to make the mounting pin retract inward, so that the mounting rod can be smoothly inserted into the bottle body and thus engage with the mounting groove.
[0017] In some embodiments, the mounting groove includes a groove body and a mounting hole, the groove body extends circumferentially along the bottle body and gradually increases in depth, and the mounting hole is disposed on the side of the groove body with the greatest depth.
[0018] In this embodiment, by setting the mounting groove to gradually increase in depth and form a mounting hole, the end of the mounting rod can gradually extend and retract as the groove depth changes during rotation, and fully extend at the mounting hole to achieve engagement between the mounting rod and the mounting hole.
[0019] In some embodiments, the mounting hole includes a communicating portion that communicates with the groove along the circumference of the bottle body and a top portion disposed on top of the communicating portion, wherein the top portion is not in communication with the groove along the circumference of the bottle body.
[0020] In this embodiment, by configuring the mounting hole as a connecting part and a top part, when the end of the mounting rod rotates from the groove to the connecting part, the mounting rod can move upward to the top part under the action of the first telescopic mechanism. Since the top part is not connected to the groove in the circumferential direction, the mounting rod cannot be directly unscrewed by rotation, thus achieving a firm engagement between the bottle body and the bottle cap. When it is necessary to open the cap, pressing down on the mounting rod will allow its end to enter the connecting part, and then rotating it will complete the cap opening operation.
[0021] In some embodiments, the first telescopic mechanism includes a first spring connecting the mounting rod and the cover, wherein the telescopic direction of the first spring is perpendicular to the cover.
[0022] In this embodiment, a first spring is provided, allowing the mounting rod to move in a direction perpendicular to the cover body to adjust its height so that it is flush with the mounting groove. Furthermore, when the mounting rod is flush with the mounting groove, the first spring is compressed, applying an upward force to the mounting rod, which helps improve the sealing performance after the cover is closed.
[0023] In some embodiments, the first telescopic mechanism further includes a telescopic rod disposed at the center of the top surface of the cover, and the mounting portion at the center of the mounting rod is connected to the telescopic end of the telescopic rod; the first spring is disposed on the outside of the telescopic rod, and the two ends of the first spring are respectively connected to the bottom surface of the mounting portion and the top surface of the cover.
[0024] In this embodiment, by providing a telescopic rod inside the first spring, the movement of the mounting rod in the vertical direction can be guided to prevent the mounting part of the mounting rod from shifting in the horizontal direction, so that the mounting rod can move stably along the direction perpendicular to the cover.
[0025] In some embodiments, the inner wall of the bottle is provided with a limiting protrusion for supporting the bottle cap, and the mounting groove is located above the limiting protrusion.
[0026] In this embodiment, by setting a limiting protrusion, the bottle cap can be placed stably, and then the cap can be closed by rotating the mounting rod to engage with the mounting groove. The overall operation is relatively convenient.
[0027] Secondly, embodiments of this application provide an automatic opening and closing system for a grinding bottle, including the grinding bottle and opening and closing device described in the above technical solution;
[0028] The opening and closing device includes a bottle body clamping device and a bottle cap screwing device;
[0029] The bottle clamping device is used to fix the bottle body, and the bottle cap screwing device is used to drive the mounting rod to perform downward and rotational movements so that the end of the mounting rod is screwed into or out of the mounting groove;
[0030] The bottle cap screwing device includes a bottle cap clamping device, a rotating mechanism connected to the bottle cap clamping device, and a lifting mechanism connected to the rotating mechanism.
[0031] In the technical solution of this application embodiment, the bottle body is fixed by setting a bottle body clamping device and the bottle cap screwing device is screwed on the bottle cap. The lifting mechanism can drive the rotating mechanism and the bottle cap clamping mechanism to lift and lower as a whole, and the bottle cap clamping mechanism clamps the bottle cap. Then, the rotating mechanism drives the bottle cap clamping mechanism and the mounting rod in the bottle cap to rotate, so that the end of the mounting rod is screwed into or out of the mounting groove to complete the cap opening or closing operation. This realizes the automatic opening and closing of the grinding bottle, and the bottle body and the bottle cap can be reliably sealed after the cap is closed.
[0032] The above description is only an overview of the technical solution of this application. In order to better understand the technical means of this application and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this application more obvious and understandable, the following are specific embodiments of this application.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.
[0052] In existing grinding bottles, the bottle body 10 and the cap 20 are usually connected by threads. This connection means that the operation of opening and closing the cap is only rotation, and it is difficult to accurately control the end point of rotation when opening and closing the cap. This makes it easy for the grinding bottle to loosen when it is rotated on the grinding machine after the cap is closed, resulting in material leakage.
[0053] To prevent the grinding bottle from loosening and leaking due to rotation, this application provides a grinding bottle in which the bottle body 10 and the cap 20 are connected by a mounting groove and a mounting rod 21 respectively at a specific position. This makes it possible to open or close the grinding bottle by pressing and rotating in two steps, thus ensuring that the opening and closing of the cap is convenient while preventing the grinding bottle from loosening and leaking when rotating on the grinding machine after the cap is closed.
[0054] Specifically, this application provides a grinding bottle, including a bottle body 10 and a bottle cap 20;
[0055] The bottle body 10 has a receiving cavity for accommodating the grinding rod 13 and the sample, and the inner wall of the bottle body 10 is provided with a mounting groove;
[0056] The bottle cap 20 includes a cap body 22, a mounting rod 21, and a first telescopic mechanism connecting the cap body 22 and the mounting rod 21; the telescopic direction of the first telescopic mechanism is perpendicular to the cap body 22.
[0057] When the mounting rod 21 is aligned with the mounting groove in the height direction, the end of the mounting rod 21 can be screwed into or out of the mounting groove, and the first telescopic mechanism is used to apply an upward force to the mounting rod 21.
[0058] In the technical solution of this application embodiment, the connection between the bottle body 10 and the cap 20 in the grinding bottle is not a conventional threaded connection. Instead, the bottle body 10 and the cap 20 are engaged at a specific position through an mounting groove and a mounting rod 21. By pressing the mounting rod 21 to make it flush with the mounting groove, the end of the mounting rod 21 can be screwed into or out of the mounting groove by rotating it, thereby opening or closing the grinding bottle. This not only allows for precise control of the tightening degree, enabling simple and efficient opening and closing of the cap, but also prevents the grinding bottle from loosening and leaking material when rotating on the grinding machine after being capped.
[0059] Furthermore, in some embodiments of this application, the structural schematic diagram of the grinding bottle is as follows: Figure 1 As shown. The grinding bottle includes a bottle body 10 and a bottle cap 20. The bottle cap 20 is located in the upper part of the inner cavity of the bottle body 10, and the bottle cap 20 is engaged with the bottle body 10 by a telescopic mounting rod 21 and a mounting groove. For details, please refer to the reference. Figure 1 , Figure 2 The bottle body 10 has a cavity for accommodating the grinding rod 13 and the sample. The inner wall of the cavity of the bottle body 10 protrudes outward to form a limiting protrusion 12 for supporting the bottle cap 20. The cap 22 of the bottle cap 20 can be placed directly on the limiting protrusion 12. The mounting groove provided on the inner wall of the bottle body 10 is located above the limiting protrusion 12. Its height is determined according to the position of the mounting rod 21 above the cap 22, so that the mounting rod 21 can be aligned with the mounting groove in the vertical direction after being pressed.
[0060] Furthermore, in some embodiments of this application, the number of mounting slots is preferably two, and the two mounting slots are symmetrically arranged with respect to the center of the bottle body 10. Each mounting slot includes a slot body 11 and a mounting hole 111. The slot body 11 extends circumferentially along the bottle body 10 and its depth gradually increases. The mounting hole 111 is provided on the side of the slot body 11 with the greatest depth. With this arrangement, the direction in which the depth of the slot body 11 gradually increases is the cap-closing direction, and vice versa is the cap-opening direction. When the end of the mounting rod 21 enters the slot body 11 and rotates in the cap-closing direction, the end of the mounting rod 21 gradually extends and fully protrudes from the mounting hole 111, so that the mounting rod 21 engages with the mounting slot, completing the cap-closing operation. More preferably, when the end of the mounting rod 21 is fully extended, its end is still located inside the mounting hole 111 and does not extend beyond the bottle body 10. That is, when the end of the mounting rod 21 is located inside the mounting hole 111, the overall length of the mounting rod 21 is neither less than the overall length corresponding to the maximum depth of its end in the groove 11, nor greater than the diameter of the outer wall of the bottle body 10. This makes it easy to unscrew the mounting rod 21 out of the mounting groove without affecting the rotation of the grinding bottle on the grinding machine.
[0061] Furthermore, such as Figure 3 As shown, in some embodiments of this application, the first telescopic mechanism includes a first spring 24 connecting the mounting rod 21 and the cover 22, and a telescopic rod 23 disposed in the middle of the top surface of the cover 22; wherein the telescopic directions of the first spring 24 and the telescopic rod 23 are both perpendicular to the top surface of the cover 22. The mounting portion 211 in the middle of the mounting rod 21 is connected to the telescopic end of the telescopic rod 23, and the first spring 24 is sleeved on the outside of the telescopic rod 23. The two ends of the first spring 24 are respectively connected to the bottom surface of the mounting portion 211 and the top surface of the cover 22. When the end of the mounting rod 21 is engaged with the mounting groove, the first spring 24 is in a compressed state, which is used to apply an upward force to the mounting rod 21, pushing the mounting rod 21 upward as much as possible to improve the sealing degree of the cover.
[0062] Specifically, in order to further improve the firmness of the cap after closing while ensuring convenient opening and closing, in some embodiments of this application, the mounting hole 111 includes a connecting portion that communicates with the groove 11 along the circumference of the bottle body 10 and a top portion disposed at the top of the connecting portion. The top portion is not connected to the groove 11 in the circumference of the bottle body 10. With this configuration, by pressing down on the mounting rod 21 so that the end of the mounting rod 21 is located in the groove 11, and then rotating it in the closing direction into the connecting portion of the mounting hole 111, and then stopping the pressing down on the mounting rod, the first spring 24 can be used to push the mounting rod 21 upward, so that the end of the mounting rod 21 enters the top portion of the mounting hole 111. Since the top portion is not connected to the groove 11 in the circumference of the bottle body 10, the mounting rod 21 cannot be disengaged from the mounting groove by rotation alone, thereby achieving a firm engagement between the bottle body 10 and the cap 20. When it is necessary to open the cap, simply press down on the mounting rod 21 so that its end moves from the top part of the mounting hole 111 to the connecting part, and then rotate it in the opening direction so that the end of the mounting rod 21 gradually disengages from the mounting groove, thereby loosening the bottle body 10 from the cap 20 and completing the cap opening operation.
[0063] Furthermore, please refer to the following: Figure 3 , Figure 4 In some embodiments of this application, the mounting rod 21 includes a mounting portion 211, a sleeve 212, and a mounting pin 213. The mounting portion 211 is connected to the telescopic end of the telescopic rod 23. The sleeve 212 is symmetrically arranged on both sides of the mounting portion 211, and the mounting pin 213 is disposed at one end of the sleeve 212 away from the mounting portion 211. A second telescopic mechanism is provided between the sleeve 212 and the mounting pin 213 for extending and retracting the mounting pin 213 along the axial direction of the sleeve 212. More specifically, the second telescopic mechanism includes a second spring 214 connecting the sleeve 212 and the mounting pin 213, a guide pin 215 disposed in the sleeve 212, and a guide hole 2131 disposed in the mounting pin 213. The extension and retraction direction of the second spring 214 is the axial direction of the sleeve 212, the guide pin 215 is disposed radially along the sleeve 212, and the guide hole 2131 is disposed axially along the sleeve 212, with the guide pin 215 located within the guide hole 2131.
[0064] Based on the above embodiment, the mounting pin 213 can extend and retract relative to the sleeve 212 to adapt to different depths within the mounting groove. When the end of the mounting pin 213 abuts against the inner wall of the bottle 10, the second spring 214 is in a compressed state, continuously applying an outward force to the mounting pin 213, causing it to extend outward along the axial direction of the sleeve 212. As the mounting pin 213 rotates within the mounting groove in the capping direction, the second spring 214 gradually extends, causing the mounting pin 213 to gradually extend outward. When the mounting pin 213 rotates into the mounting hole 111, the second spring 214 extends to its natural length, at which point the overall length of the mounting rod 21 is at its longest. If it is necessary to open the cap, rotate the mounting rod 21 in the opening direction. The inner wall of the groove 11 will push the mounting pin 213 to retract inward along the direction of the guide hole 2131, thereby compressing the second spring 214. When the mounting rod 21 is rotated out of the mounting groove, the overall length of the mounting rod 21 is the shortest. At this time, the overall length of the mounting rod 21 is the diameter of the inner wall of the bottle 10.
[0065] Furthermore, in some embodiments of this application, since the overall length of the mounting rod 21 in its natural state is greater than the inner diameter of the bottle body 10, in order to facilitate the repositioning of the cap 22 onto the limiting protrusion 12 after the cap 20 is removed and to allow the mounting rod 21 to enter the bottle body 10, it is preferable to set the side of the mounting pin 213 away from the sleeve 212 facing the cap 22 as an inclined surface.
[0066] Based on the above embodiment, when the bottle cap 20 is placed, the inclined surface of the mounting pin 213 will retract inward and compress the second spring 214 after contacting the inner wall edge of the bottle body 10, thereby shortening the overall length of the mounting pin 213 and entering the bottle body 10, ensuring that the bottle cap 20 can be placed normally on the limiting protrusion 12. On this basis, automatic cap closing can be achieved by rotating and locking. Furthermore, based on the slope, the overall length of the mounting rod 21 corresponding to the second spring 214 at its natural length can be greater than the inner diameter of the bottle 10 corresponding to the deepest part of the groove 11. This makes the overall length of the mounting rod 21 greater than the overall length corresponding to the maximum depth of the groove 11 when the mounting pin 213 is located in the mounting hole 111. When the mounting rod 21 is rotated in the capping direction, it can be further extended when the mounting pin 213 is screwed into the mounting hole 111. At this time, regardless of whether the mounting hole 111 has a top part that is not circumferentially connected to the groove 11, the mounting pin 213 cannot be directly screwed out of the mounting hole 111 by reverse rotation, which effectively improves the locking firmness between the bottle 10 and the cap 20 in the capped state. When it is necessary to open the cap, by further pressing down on the mounting rod 21, the bottom surface of the mounting hole 111 can apply an upward force to the inclined surface of the mounting pin 213, thereby pushing the mounting pin 213 to squeeze the second spring 214 inward, so that the overall length of the mounting rod 21 is shortened. When the overall length of the mounting rod 21 is shortened to the inner diameter of the bottle body 10 corresponding to the deepest part of the groove 11, the mounting rod 21 can be rotated in the opening direction to unscrew the mounting rod 21 out of the mounting hole 111, thus completing the cap opening operation.
[0067] Secondly, this application also provides an automatic opening and closing system for a grinding bottle, including the grinding bottle and opening and closing device described in the above embodiments;
[0068] The opening and closing device includes a bottle body clamping device and a bottle cap screwing device;
[0069] The bottle clamping device is used to fix the bottle body, and the bottle cap screwing device is used to drive the mounting rod to perform downward and rotational movements so that the end of the mounting rod is screwed into or out of the mounting groove;
[0070] The bottle cap screwing device includes a bottle cap clamping device, a rotating mechanism connected to the bottle cap clamping device, and a lifting mechanism connected to the rotating mechanism.
[0071] In the technical solution of this application embodiment, a corresponding opening and closing device is designed for the grinding bottle. On the one hand, the bottle body clamping device 60 is used to fix the bottle body 10, and on the other hand, the bottle cap screwing device is used to drive the mounting rod 21 in the bottle cap 20 to perform downward and rotational movements, so that the end of the mounting rod 21 is screwed into or out of the mounting groove, thereby realizing automated cap opening and closing operations.
[0072] Specifically, in some embodiments of this application, the structural schematic diagram of the opening and closing device is as follows: Figure 5 As shown, the opening and closing device is installed on the workbench 70, which has several grinding bottle opening and closing stations. Each station corresponds to a set of opening and closing devices. The number of stations and opening and closing devices can be set according to actual needs. Preferably, two grinding bottle opening and closing stations are set, which can be used for cap closing and cap opening operations respectively. Specifically, the bottle clamping device 60 is set on the table surface of the workbench 70, including two bottle clamping parts located on both sides of the grinding bottle opening and closing station. The space formed between the two bottle clamping parts to accommodate the grinding bottle is the grinding bottle opening and closing station. The bottle cap screwing device is vertically set on one side of the bottle clamping device 60. The bottle cap clamping device 30 is located directly above the grinding bottle opening and closing station. The lifting mechanism 50 and the rotating mechanism are used to drive the bottle cap clamping device 30 to lift and rotate, respectively. With this setup, the grinding bottle only needs to be placed in the grinding bottle opening / closing station. The bottle clamping part can then hold the grinding bottle, and the lifting mechanism 50 can lower the cap clamping device 30 to the position of the cap 20. Through the cooperation of the lifting mechanism 50 and the rotating mechanism, the mounting rod 21 in the cap 20 can be clamped and rotated, causing the end of the mounting rod 21 to disengage from or enter the mounting groove, thus achieving automatic cap opening and closing. The operation of placing the grinding bottle in the grinding bottle opening / closing station can be performed by a robotic arm to achieve full automation.
[0073] It should be noted that the opening and closing device in this application is not limited to... Figure 5 In the structure shown, the bottle clamping device in the opening and closing device only needs to be able to fix the bottle 10, and the bottle cap screwing device only needs to be able to drive the mounting rod 21 in the bottle cap 20 to perform downward and rotational movements so that the end of the mounting rod 21 screws into or out of the mounting groove. Both of these are within the protection scope of this application. The specific structure of the opening and closing device will be described below using only one embodiment of this application as an example.
[0074] Please refer to the following: Figure 6 In some embodiments of this application, the bottle cap screwing device includes a lifting mechanism 50 mounted on a workbench 70, a rotating mechanism connected to the lifting mechanism 50, and a bottle cap clamping device 30 connected to the rotating mechanism. The bottle cap clamping device 30 is located directly above the bottle opening / closing station. The lifting mechanism 50 drives the rotating mechanism and the bottle cap clamping device 30 to move up and down as a whole, so that the bottle cap clamping device 30 moves away from or closer to the bottle cap 20. The rotating mechanism drives the bottle cap clamping device 30 to rotate around the central axis of the bottle body 10. With the cooperation of the rotating mechanism and the lifting mechanism 50, the bottle cap clamping device 30 can clamp the bottle cap 20 and drive the mounting rod 21 in the bottle cap 20 to rotate, thereby completing the opening and closing operations.
[0075] Please refer to the following: Figure 7 In some embodiments of this application, the bottle cap clamping device 30 includes a pressure plate 31 connected to a rotating mechanism and two clamping plates 32 spaced apart at the bottom of the pressure plate 31. The two clamping plates 32 and the pressure plate 31 surround and form a receiving space for accommodating the mounting rod 21. When the two clamping plates 32 abut against the two sides of the mounting rod 21 respectively, the mounting rod 21 is clamped. Preferably, a pressure sensor 322 is provided on the inner wall of the clamping plate 32 to detect whether the clamping plate 32 abuts against the mounting rod 21.
[0076] Specifically, to more stably clamp the mounting rod 21, the shape of the clamping plate 32 can be determined according to the shape of the mounting rod 21. In some embodiments of this application, since the mounting rod 21 has a mounting part 211 in the middle and sleeves 212 on both sides of the mounting part 211, and the clamping plate 32 is mainly used to clamp the sleeves 212 in the mounting rod 21, thereby driving the mounting rod 21 to rotate, a clearance part 321 for avoiding the mounting part 211 is provided in the middle of the clamping plate 32 at a position corresponding to the mounting part 211. The shape of the clearance part 321 can be completely consistent with the mounting part 211, or it can be adjusted as needed to ensure that the cavity formed between the clearance parts 321 of the two clamping plates 32 can completely accommodate the mounting part 211. The pressure sensor 322 can also be set in the clearance part 321, as long as the mounting part 211 can squeeze the pressure sensor 322 in the clamping state. The positions on both sides of the clamping plate 32 corresponding to the sleeve 212 of the mounting rod 21 are the sleeve 212 clamping parts. In the clamping state, the sleeve 212 clamping parts of the two clamping plates 32 are located on both sides of the sleeve 212. When the two clamping plates 32 are rotated under the drive of the rotating mechanism, the sleeve 212 clamping parts can abut against the sleeve 212 and drive the sleeve 212 to rotate around the central axis of the bottle body 10.
[0077] Furthermore, in this embodiment, the two clamping plates 32 only need to be located on both sides of the mounting rod 21, capable of rotating the mounting rod 21. After the cap opening operation, a robotic arm can be used to remove the cap 20 so that the sample and grinding rod 13 can be loaded into the bottle body 10. If it is necessary to use the clamping plates 32 to clamp the cap 20 and lift it after opening, an additional drive mechanism can be provided as needed to control the two clamping plates 32 to move closer or further apart. This application is not limited to this.
[0078] Please refer to the following: Figure 6In some embodiments of this application, the rotating mechanism includes a rotary motor 41 connected to the bottle cap clamping device 30, a first fixing structure 42 for fixing the rotary motor 41, and a first connecting plate 43 for connecting the first fixing structure 42 and the lifting mechanism 50. The output shaft of the rotary motor 41 is connected to the pressure plate 31 of the bottle cap clamping device 30. This output shaft is collinear with the central axis of the bottle body 10, enabling the bottle cap clamping device 30 to drive the mounting rod 21 to rotate around the central axis of the bottle body 10. The output shaft of the rotary motor 41 can rotate forward and backward to complete the opening and closing operations.
[0079] Please refer to the following: Figure 6 , Figure 8 In some embodiments of this application, the lifting mechanism 50 includes a second fixed structure 53 mounted on the workbench 70, a telescopic cylinder 51 mounted on the second fixed structure 53 and extending and retracting vertically, and a second connecting plate 52 for connecting the telescopic end of the telescopic cylinder 51 and the first connecting plate 43. Thus, the telescopic cylinder 51's extension and retraction movement can drive the rotating mechanism and the bottle cap clamping device 30 to move up and down. More preferably, to ensure the stability of the lifting process, a lifting guide rod 54 is also provided on the second fixed structure 53. The axial direction of the lifting guide rod 54 is consistent with the extension and retraction direction of the telescopic cylinder 51. A lifting guide slider 55 is provided on the lifting guide rod 54, and the lifting guide slider 55 is connected to the first connecting plate 43. This arrangement ensures that when the telescopic cylinder 51 drives the first connecting plate 43 to move, it moves along the axial direction of the lifting guide rod 54. The number of lifting guide rods 54 can be set as needed, preferably two, and the two lifting guide rods 54 are symmetrically arranged on both sides of the telescopic cylinder 51, further improving the stability of the lifting process. More preferably, a lifting limit rod 56 is also provided at the lower part of the second fixing structure 53, and the lifting limit rod 56 is located below the second connecting plate 52; when the second connecting plate 52 descends to abut against the top of the lifting limit rod 56, the second connecting plate 52 stops descending, and at this time the bottle cap clamping device reaches the preset working height. This setting facilitates accurate control of the descent position of the bottle cap clamping device, so as to effectively clamp the bottle cap.
[0080] Please refer to the following: Figure 9 , Figure 10In some embodiments of this application, the bottle clamping device 60 includes a bottle clamping structure, a driving mechanism, a supporting structure, and a bottle positioning mechanism 67. The bottle clamping structure includes a first base 611 and a second base 612 respectively disposed on both sides of the grinding bottle opening / closing station. A first bottle clamping part 621 is disposed in the middle of the first base 611, and a second bottle clamping part 622 is disposed in the middle of the second base 612. With this configuration, by driving and supporting the first base 611 and the second base 612, the first bottle clamping part 621 and the second bottle clamping part 622 can be stably translated to clamp the bottle 10. Preferably, the opposing sidewalls of the first bottle clamping part 621 and the second bottle clamping part 622 are configured as contoured structures matching the shape of the outer wall of the bottle 10 to effectively clamp the bottle 10.
[0081] The drive mechanism moves the first base 611 and the second base 612 closer or further apart, thereby enabling the first bottle clamping part 621 and the second bottle clamping part 622 to move closer or further apart. Specifically, the drive mechanism includes a drive gear 631 and a first rack 632 and a second rack 633 meshing with the drive gear 631. The drive gear 631 is driven by a motor that can rotate in both forward and reverse directions. The first rack 632 is located on the upper part of the drive gear 631 and is connected to the first base 611 via a first connector 641. The second rack 633 is located on the lower part of the drive gear 631 and is connected to the second base 612 via a second connector 642. With this configuration, when the drive gear 631 rotates, it can drive the first rack 632 and the second rack 633 to move in opposite directions, thereby causing the first bottle clamping part 621 on the first base 611 and the second bottle clamping part 622 on the second base 612 to move closer to or further away from each other, so as to clamp or release the bottle 10.
[0082] The support structure includes a first support mechanism located near the drive mechanism and a second support mechanism located away from the drive mechanism. The first support mechanism includes a first guide rod 651, a first guide slider 652 mounted on the first guide rod 651, and a first mounting base 653 for fixing the first guide rod 651. The first mounting base 653 is directly fixed to the worktable 70, preferably two of them, symmetrically arranged at both ends of the first guide rod 651, and located on the outer side below the first base 611 and the second base 612, respectively. The first guide slider 652 is also preferably two, connected to the first base 611 and the second base 612, respectively. The axial direction of the first guide rod 651 is parallel to the movement direction of the first rack 632 and the second rack 633. The second support mechanism includes a second guide rod 661, a second guide slider 662 mounted on the second guide rod 661, a second mounting base 663 for fixing the second guide rod 661, and a base 664 mounted on the worktable 70. The second mounting base 663 is fixed on the upper surface of the base 664. Preferably, two mounting bases are provided, symmetrically arranged at both ends of the second guide rod 661, and the two mounting bases 663 are respectively located below the first base 611 and the second base 612. The second guide slider 662 is also preferably two, respectively connected to the first base 611 and the second base 612. The axial direction of the second guide rod 661 is parallel to the moving direction of the first rack 632 and the second rack 633. With this configuration, when the first rack 632 and the second rack 633 respectively drive the first base 611 and the second base 612 to translate, the end of the first base 611 and the second base 612 closer to the driving mechanism will translate along the first guide rod 651 under the action of the first guide slider 652, while the end of the first base 611 and the second base 612 farther from the driving mechanism will translate along the second guide rod 661 under the action of the second guide slider 662. This ensures that the first base 611 and the second base 612 are stably close to or far from each other, thereby improving the clamping effect on the bottle 10.
[0083] The bottle positioning mechanism 67 includes a positioning groove 671 disposed on the bottle opening and closing station for accommodating the bottle body 10. Several limiting blocks 672 are also disposed on the outside of the positioning groove 671 to stably position the bottle body 10 within the positioning groove 671. To prevent the bottle cap 20 from rotating and causing the bottle body 10 to rotate, a groove is provided on the side wall at the bottom of the bottle body 10. The bottle positioning mechanism 67 also includes an engaging component for engaging with the groove. The engaging component is disposed on the outside of the positioning groove 671 and includes a telescopic part 673 and a fixing part 674 disposed radially along the bottle body 10. The telescopic part 673 is disposed on the side close to the positioning groove 671 and is slidably connected to a first sliding groove 675 extending radially along the bottle body 10. A positioning spring 676, which extends and retracts radially along the bottle body 10, is disposed between the telescopic part 673 and the fixing part 674. A protrusion 6731 extending towards the bottle body 10 is provided on the side of the telescopic part 673 near the positioning groove 671, for engaging with the groove on the side wall of the bottle body 10. In order to drive the telescopic part 673 to perform telescopic movement, the bottle positioning mechanism 67 also includes a moving component, which is provided on one side of the telescopic part 673, including a second slide groove 677 extending in a direction perpendicular to the first slide groove 675 and a positioning slider 678 slidably connected to the second slide groove 677; a fixing post 6732 is provided on the top of the telescopic part 673, and an inclined surface facing the fixing part 674 is provided on one end of the positioning slider 678 near the fixing post 6732. The positioning slider 678 is also connected to the moving bracket 679.
[0084] In this way, when it is necessary to place or remove the bottle 10, the moving bracket 679 is moved manually or by an additional drive mechanism. This causes the positioning slider 678 to move along the second slide groove 677 until the inclined surface of the positioning slider 678 contacts the fixing post 6732. Continuing to move the positioning slider 678 further pushes the fixing post 6732 using the inclined surface, which in turn moves the telescopic part 673 and its protrusion 6731 towards the fixing part 674. This compresses the telescopic part 673, ensuring that the protrusion 6731 is located radially outside the positioning groove 671, facilitating the free placement or removal of the bottle 10. When it is necessary to fix the bottle, the positioning slider 678 is moved away from the fixing post 6732. Under the action of the positioning spring 676, the telescopic part 673 moves the protrusion 6731 towards the bottle 10, engaging with the groove on the side wall of the bottle 10, thus fixing the bottle.
[0085] The following is a detailed description of the opening and closing process of the automatic opening and closing system for grinding bottles provided in one embodiment of this application:
[0086] When it is necessary to open the grinding bottle, the specific procedure is as follows:
[0087] S1. The bottle clamping device 60 is controlled to fix the bottle 10 in the grinding bottle opening and closing position. A robotic arm can be used to place the grinding bottle in the grinding bottle opening and closing position, and then the drive motor drives the drive gear 631 to rotate in the forward direction, which in turn drives the first rack 632 and the second rack 633 to move closer to each other, thereby driving the first bottle clamping part 621 and the second bottle clamping part 622 to move closer to each other until the bottle 10 is clamped. At this time, the two clamping parts can no longer move closer, and the corresponding drive motor can be turned off.
[0088] S2. Position the mounting rod 21 and clamp it using the bottle cap clamping device 30. By controlling the extension end of the telescopic cylinder 51 to extend outward, the rotating mechanism and the bottle cap clamping device 30 are lowered as a whole until the bottle cap clamping device 30 is lowered to the preset working height. At this time, the first spring 24 is in a compressed state and will continuously apply an upward force to the mounting rod 21. Then, control the rotary motor 41 to rotate, which will drive the clamping plate 32 to rotate. When the clamping plate 32 rotates to the same angle as the mounting rod 21, the mounting rod 21 can be pushed into the receiving space between the two clamping plates 32 under the action of the first spring 24. The pressure sensor 322 in the clamping plate 32 can detect the corresponding pressure information and complete the clamping of the mounting rod 21. At this time, the mounting rod 21 and the mounting groove are aligned in the vertical direction, the mounting pin 213 at the end of the mounting rod 21 is in the connecting part of the mounting hole 111, and the overall length of the mounting rod 21 is consistent with the inner diameter of the bottle body 10 corresponding to the deepest part of the groove 11.
[0089] S3. The control rotation mechanism drives the mounting rod 21 to rotate along the opening direction, causing the mounting pin 213 at the end of the mounting rod 21 to gradually disengage from the mounting groove along the opening direction. The rotation angle of the rotation mechanism can be determined based on the circumferential curvature of the mounting groove, ensuring that the mounting pin 213 disengages from the mounting groove after rotation. Once the mounting pin 213 disengages from the mounting groove, the bottle cap 20 is merely placed on the limiting protrusion 12 of the bottle body 10; the two are not engaged. At this point, the opening is complete. The lifting mechanism 50 can then raise the bottle cap clamping device 30 to its initial position. The bottle cap 20 placed on the limiting protrusion 12 can be removed by a robotic arm to allow the sample and grinding rod 13 to be added into the bottle body 10. If it is necessary to remove the bottle body 10, the drive gear 631 can be driven to rotate in the opposite direction, causing the first bottle body clamping part 621 and the second bottle body clamping part 622 to move away from each other, and then the robotic arm can remove the bottle body 10.
[0090] When it is necessary to cap the grinding bottle, the specific procedure is as follows:
[0091] S1. Control the bottle clamping device 60 to fix the bottle 10 in the grinding bottle opening / closing position. This step is the same as the cap opening operation and will not be described again here. If the bottle 10 is already in the grinding bottle opening / closing position and is effectively clamped by the bottle clamping device 60, you can proceed directly to the next step.
[0092] S2. Position the mounting rod 21 and clamp it using the bottle cap clamping device 30. This step is the same as the cap opening operation and will not be described again here. The bottle cap 20 can be placed on the limiting protrusion 12 of the bottle body 10 by a robotic arm.
[0093] S3. Control the rotating mechanism to drive the mounting rod 21 to rotate along the capping direction, so that the mounting pin 213 at the end of the mounting rod 21 gradually enters the mounting groove along the capping direction. The rotation angle of the rotating mechanism is determined by rotating until it can no longer rotate. When it can no longer rotate, it is confirmed that the mounting pin 213 is in the mounting hole 111. At this time, the first spring 24 is in a compressed state and will continuously apply an upward force to the mounting rod 21. Then, control the telescopic cylinder 51 to retract inward, driving the bottle cap clamping device 30 to rise to its original position. The mounting rod 21 can then move upward under the action of the first spring 24 until the mounting pin 213 is located at the top of the mounting hole 111, causing the bottle cap 20 to engage with the bottle body 10, thus completing the capping operation. To remove the capped grinding bottle, drive the drive gear 631 to rotate in the opposite direction, causing the first bottle body clamping part 621 and the second bottle body clamping part 622 to move away from each other, and then use a robotic arm to remove the grinding bottle.
[0094] Through the above methods, the automatic opening and closing system for grinding bottles provided in this application can realize the automatic opening and closing of grinding bottles. The operation process is simple and easy to control. After the bottle body 10 and the bottle cap 20 are closed, they can be reliably sealed, avoiding the problem of material leakage during the grinding process.

The above embodiments are merely examples, and any embodiments with the same structure and effect as the technical concept within the scope of this application are included in the technical scope of this application. Furthermore, various modifications that can be conceived by those skilled in the art to the embodiments, and other ways of constructing by combining some of the constituent elements of the embodiments, without departing from the spirit of this application, are also included in the scope of this application.
