Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "several" is two or more, unless otherwise clearly and specifically defined.

[0031] Please also read Figures 1 to 9 , the lathe for processing the medicine column provided by the present invention is now described. The medicine column processing lathe comprises a frame 1, a rotary chuck 2, a feeding strip seat 3, a push rod 31, a cutting tool 4 and a tightening seat 5. The rotary chuck 2 is arranged on the frame 1 and is located between the feeding strip seat 3 and the tightening seat 5. The rotary chuck 2 is provided with a horizontal through hole 21 for the medicine column 9 to pass through. The push rod 31 is located at one end of the feeding strip seat 3 away from the rotary chuck 2 and is used to push the medicine column 9 so that the medicine column 9 enters the through hole 21. The cutting tool 4 is located on one side of the main shaft of the rotary chuck 2 and is used to cut or cut the medicine column 9. The tightening seat 5 is connected to the frame 1 in a sliding manner along the axial direction of the rotary chuck 2. A tightening sleeve 52 is rotatably connected to the tightening seat 5. The end face of the tightening sleeve 52 is used to abut against the end face of the medicine column 9 to limit the axial position of the medicine column 9.

[0032] Compared with the prior art, the drug column processing lathe provided in this embodiment uses a push rod 31 to push the drug column 9 on the loading strip seat 3 into the feeding hole 21 of the rotating chuck 2, and uses the rotating chuck 2 to clamp the drug column 9 and drive the drug column 9 to rotate. The tightening seat 5 can use the tightening sleeve 52 to limit the outer end surface of the drug column 9, and then use the cutting tool 4 to cut or cut the drug column 9, thereby ensuring the accuracy of the processing diameter or processing length of the drug column 9, improving the cutting efficiency of the drug column 9, and avoiding safety hazards during the processing of the drug column 9.

[0033] In this embodiment, the cutting tool 4 can not only cut the outer wall of the medicine column 9, but also cut the length of the medicine column 9 to a fixed length, and the cutter head 41 is selected and replaced according to the above different requirements. When the cutting tool 4 cuts the outer wall of the medicine column 9, the cutting tool 4 can move along the axial direction of the medicine column 9 to ensure that different parts of the medicine column 9 are processed. When the cutting tool 4 cuts the medicine column 9 to a fixed length, the cutting tool 4 can move horizontally along the radial direction of the medicine column 9 to achieve effective cutting of the medicine column 9 and meet the length requirements of the medicine column 9.

[0034] When the lathe processes the grain 9, multiple steps such as loading, positioning, and cutting can be completed without manual operation, thus avoiding the potential safety hazards of manual operation and ensuring the accuracy of grain processing.

[0035] The loading bar seat 3 is provided with a supporting groove which opens upward and is arranged along its extension direction, and the supporting groove is used to support the drug column 9. The cross section of the supporting groove can be set to different shapes such as V-shaped, U-shaped or rectangular. There are many ways to load the drug column 9, which can be a mechanical arm clamping the drug column 9 for loading, a telescopic part horizontally pushing the drug column 9 for loading, or a lifting arm pushing upward for loading.

[0036] The medicine column 9 on the feeding strip seat 3 is pushed by the pushing rod 31 and can generate axial movement to enter the feeding hole 21 of the rotating chuck 2. The medicine column 9 gradually extends from the feeding hole 21 and approaches the tightening seat 5. The tightening seat 5 can limit the end face of the medicine column 9 with the help of the tightening sleeve 52, so as to cooperate with the cutting tool 4 to realize the fixed-length cutting of the medicine column 9.

[0037] The tightening sleeve 52 can rotate relative to the tightening seat 5 to facilitate the rotation of the medicine column 9, so as to realize the cutting or cutting effect of the cutting tool 4 on the medicine column 9, avoid damage to the medicine column 9, and ensure the smoothness of the cutting process.

[0038] In one possible implementation, please also refer to Figures 1 to 9 A lower slide 32 capable of axially moving along the rotating chuck 2 is provided on the frame 1, an upper slide 38 capable of axially moving along the rotating chuck 2 is provided on the lower slide 32, a push rod 31 is connected to the upper slide 38 and can move axially driven by the upper slide 38 or the lower slide 32, or the push rod 31 moves in a manner in which the upper slide 38 and the lower slide 32 work together, a first driving member 12 for driving the lower slide 32 is connected to the frame 1, and a second driving member 36 for driving the upper slide 38 is connected to the lower slide 32.

[0039] In this embodiment, when the pushing rod 31 is used to axially push the medicine column 9 on the loading strip seat 3, in order to meet the requirement of the pushing length, the frame 1 is also provided with a lower sliding seat 32 which is slidably connected to the frame 1. The lower sliding seat 32 is located on the side of the loading strip seat 3 away from the rotating chuck 2, and an upper sliding seat 38 is arranged on the lower sliding seat 32.

[0040] In order to avoid the medicine column 9 above the loading bar seat 3, the upper slide 38 and the lower slide 32 can be moved to the extreme position away from the rotating chuck 2 to fully avoid the medicine column 9. Afterwards, the upper slide 38 drives the push rod 31 to move toward the side close to the rotating chuck 2, so that the medicine column 9 moves axially into the feeding hole 21. If the movement displacement of the medicine column 9 is insufficient, the lower slide 32 can also be moved toward the side close to the rotating chuck 2 to drive the upper slide 38 and the push rod 31 to move, so as to fully push the medicine column 9 and meet the movement range requirement of the medicine column 9.

[0041] According to the requirement of the movement range of the push rod 31, the push rod 31 can be driven to move by the upper slide 38, the lower slide 32 can be moved to drive the push rod 31, or the upper slide 38 and the lower slide 32 can be moved synchronously to drive the push rod 31.

[0042] On this basis, the frame 1 is provided with a first guide rail 11 extending axially along the rotating chuck 2, the lower slide seat 32 is slidably connected to the first guide rail 11, the lower slide seat 32 is provided with a second guide rail 37 arranged parallel to the first guide rail 11, and the upper slide seat 38 is slidably connected to the second guide rail 37.

[0043] The first driving member 12 is used to drive the lower slide 32 to move along the first guide rail 11. The first driving member 12 has a fixed portion connected to the frame 1 and a pushing portion that can move horizontally along the fixed portion. The pushing portion can drive the lower slide 32 to move along the first guide rail 11, ensuring smooth sliding of the lower slide 32. The structure of the second driving member 36 is similar to that of the first driving member 12, and can effectively push the upper slide 38, ensuring smooth movement of the upper slide 38 along the second guide rail 37, and realizing the driving effect on the push rod 31.

[0044] The arrangement of the above structure can meet the pushing requirements of medicine columns 9 of various lengths, and is convenient for reducing the space occupied by the structure in the axial direction of the medicine column 9. While utilizing a smaller space, it is convenient to increase the stroke of the pushing rod 31, thereby meeting the pushing requirements of medicine columns 9 of various sizes.

[0045] On the basis of the above structure, the upper slide 38 is slidably connected to the top of the lower slide 32, and a fixed seat 311 is provided above one end of the lower slide 32 close to the rotating chuck 2, and a sliding sleeve 312 is penetrated through the fixed seat 311. One end of the push rod 31 is connected to the upper slide 38, and the other end is penetrated through the sliding sleeve 312. The sliding sleeve 312 is used to limit the peripheral wall of the push rod 31 to prevent the end of the push rod 31 from falling and affecting the corresponding relationship with the medicine column 9.

[0046] In some embodiments, please refer to Figures 1 to 9 The upper slide 38 is connected to the gravity hammer 34 through the pull rope 33, and the top and bottom surfaces of the lower slide 32 are respectively provided with pulleys 35 for guiding the pull rope 33. The frame 1 is provided with a clearance groove 13 that passes through the upper and lower parts for the pull rope 33 to pass through. The gravity hammer 34 pulls the upper slide 38 toward the side close to the rotating chuck 2 through the pull rope 33 so that the push rod 31 is pressed against the end surface of the medicine column 9.

[0047] In this embodiment, the gravity hammer 34 has a certain weight, and can form a pulling effect on the upper slide 38 through the pull rope 33, so that the upper slide 38 and the push rod 31 have a tendency to move toward the side close to the medicine column 9, and then the push rod 31 can be used to abut against the end surface of the medicine column 9, so that the medicine column 9 also has a tendency to move toward the side of the tightening seat 5. The medicine column 9 is axially limited by the tightening sleeve 52 on the tightening seat 5, which is convenient for the rotating chuck 2 to lock the axial position of the medicine column 9, thereby ensuring the accuracy of the installation position of the medicine column 9.

[0048] In one possible implementation, please also refer to Figures 1 to 9A loading hopper 6 is also provided on one side of the loading strip seat 3. A lifting and pushing arm 61 is connected to the frame 1 and extends upward into the loading hopper 6. The lifting and pushing arm 61 has an arc-shaped groove 69 for supporting a single drug column 9. The lifting and pushing arm 61 is used to push the drug column 9 upward so that the drug column 9 is transferred from the loading hopper 6 to the loading strip seat 3.

[0049] In this embodiment, the loading hopper 6 is located at the side of the loading bar seat 3, and the medicine columns 9 can be pushed one by one into the loading bar seat 3 by the lifting and pushing arm 61, so as to realize the loading of medicine columns 9 one by one. The arc groove 69 of the lifting and pushing arm 61 is used to push the single medicine column 9 in the loading hopper 6 upward to protrude from the upper edge of the loading hopper 6, and then the medicine column 9 can be unloaded by other pushing members.

[0050] Specifically, according to the different lengths of the medicine columns 9 to be loaded, a loading hopper 6 can be set on both sides of the loading bar seat 3. The two loading hoppers 6 have different widths to accommodate medicine columns 9 of different lengths. The bottom of each loading hopper 6 is loaded by a lifting and pushing arm 61.

[0051] As a parallel embodiment, in order to simplify the structural arrangement, the lifting and pushing arm 61 is arranged adjacent to the side wall of the upper hopper 6 close to the loading strip seat 3, and the side wall of the upper hopper 6 can cooperate with the arc groove 69 to limit the support of the medicine column 9. When the medicine column 9 moves up to a position higher than the upper edge of the upper hopper 6 along with the lifting and pushing arm 61, the limiting effect of the side wall of the upper hopper 6 is lost, and the medicine column 9 can automatically roll out of the arc groove 69 and be transferred to the loading strip seat 3.

[0052] On this basis, a connecting plate 611 is further provided between the upper hopper 6 and the loading strip seat 3. The connecting plate 611 gradually extends downward from the side close to the upper hopper 6 to the side close to the loading strip seat 3, so that the medicine column 9 can roll along the plate surface of the connecting plate 611 into the loading strip seat 3, thereby realizing smooth loading of the medicine column 9.

[0053] In some embodiments, please refer to Figures 1 to 9 The bottom of the upper hopper 6 is rotatably connected to a lifting plate 62 that can be lifted upward to allow the medicine column 9 to roll down to the lifting and pushing arm 61. The frame 1 is rotatably connected to a swinging pull plate 63 located below the lifting plate 62. The lifting and pushing arm 61 is provided with a vertical long groove 64 extending in the up and down directions. The swinging pull plate 63 is provided with a slide bar 65 slidably connected to the vertical long groove 64. The lifting and pushing arm 61 is used to drive the swinging pull plate 63 to swing vertically, and the swinging pull plate 63 is used to push the lifting plate 62 to swing upward to push the medicine column 9 to the top of the lifting and pushing arm 61.

[0054] In this embodiment, a lifting plate 62 is also provided at the bottom of the upper hopper 6. The lifting plate 62 is hingedly connected to the upper hopper 6. The lifting plate 62 can swing vertically to form a lifting effect on the drug column 9, so that the drug column 9 rolls into the arc groove 69 of the lifting and pushing arm 61 under the action of the tilt angle of the lifting plate 62.

[0055] The lifting plate 62 should lift the medicine column 9 when the lifting and pushing arm 61 moves downward, so that a single medicine column 9 can enter the arc groove 69 of the lifting and pushing arm 61. In order to simplify the structure, the lifting plate 62 can be driven by the action of the lifting and pushing arm 61. The vertical long groove 64 on the lifting and pushing arm 61 is slidably matched with the slide bar 65 of the swing pull plate 63. After the lifting and pushing arm 61 moves downward to a certain extent, one end of the swing pull plate 63 can be pulled down by the slide bar 65. At this time, the other end of the swing pull plate 63 can be lifted upward to achieve the pushing effect on the lifting plate 62, so that the medicine column 9 on the lifting plate 62 can smoothly roll down along the top surface of the lifting plate 62 into the arc groove 69 of the lifting and pushing arm 61, which is convenient for the subsequent ejection of a single medicine column 9, so that the medicine column 9 enters the subsequent feeding strip seat 3. Specifically, a plurality of vertical long grooves 64 may be arranged at intervals along the horizontal direction, and a corresponding number of sliding bars 65 are provided on the swing pull plate 63 .

[0056] Specifically, the cross section of the swing pull plate 63 is V-shaped with an upward opening, which facilitates the upward pushing of the lifting plate 62 under the downward pulling action of the lifting and pushing arm 61, thereby ensuring the effectiveness of the action and achieving a good driving effect.

[0057] On this basis, the extended end of the slide bar 65 is further provided with an anti-slip seat 66 , the width of which is greater than the width of the vertical long groove 64 , to prevent the slide bar 65 from slipping out of the vertical long groove 64 and ensure the smoothness of the movement of the swing pull plate 63 .

[0058] In some embodiments, please refer to Figures 1 to 9 The lifting and pushing arm 61 includes a lifting drive member 67 and an upper supporting seat 68. The upper supporting seat 68 is connected to the upper end of the lifting drive member 67. The vertical long groove 64 horizontally penetrates the upper supporting seat 68. The arc groove 69 is arranged on the top surface of the upper supporting seat 68. The bottom wall of the arc groove 69 extends obliquely downward close to the side of the loading strip seat 3. The side wall adjacent to the loading hopper 6 and the loading strip seat 3 can cooperate with the arc groove 69 to limit the medicine column 9.

[0059] In this embodiment, the lifting and pushing arm 61 drives the upper supporting seat 68 to move upward by using the lifting driving member 67, and then supports and limits the peripheral wall of the drug column 9 with the help of the arc groove 69 on the upper supporting seat 68, so as to facilitate the subsequent upward movement of the drug column 9.

[0060] On the basis of the above structure, the side wall of the upper support seat 68 away from the upper hopper 6 is lower than the side wall of the upper support seat 68 close to the upper hopper 6, and the side wall of the upper hopper 6 adjacent to the feeding strip seat 3 cooperates with the arc groove 69 of the upper support seat 68 to ensure the effectiveness of the upward movement of the drug column 9. When the upper support seat 68 moves up to a position higher than the upper hopper 6, the cooperation of the side wall of the upper hopper 6 is lost, and the drug column 9 will roll out of the arc groove 69 and roll into the feeding strip seat 3 through the connecting plate 611.

[0061] In one possible implementation, please also refer to Figures 1 to 9 A screw drive assembly 7 extending along the axial direction of the rotating chuck 2 is provided on the frame 1, and a telescopic drive member 51 is provided on the screw drive assembly 7 for driving the tightening seat 5 to translate toward the side close to the rotating chuck 2. The tightening seat 5 can move horizontally driven by the screw drive assembly 7 and the telescopic drive member 51 to limit the axial position of the medicine column 9.

[0062] In this embodiment, when limiting the axial position of the drug column 9, the telescopic drive member 51 is first used to drive the tightening seat 5 to extend outward, and then the screw drive assembly 7 is used to drive the tightening seat 5 and the telescopic drive member 51 to move synchronously, so that the tightening seat 5 can be moved to a preset position. The preset position is set according to the part of the drug column 9 that needs to be cut or the cutting length, so as to ensure the processing accuracy of the drug column 9.

[0063] In one possible implementation, please also refer to Figures 1 to 9 The tightening seat 5 is a plate-like component extending vertically, and the tightening sleeve 52 is horizontally penetrated through the tightening seat 5. The driving end of the screw drive assembly 7 is also provided with a drill bit 75 for drilling the medicine column 9. The drill bit 75 is penetrated through the tightening sleeve 52. The tightening sleeve 52 can be retracted under the drive of the telescopic drive member 51 to make the drill bit 75 protrude from the tightening seat 5.

[0064] In this embodiment, the telescopic driving member 51 is arranged parallel to the main axis of the rotating chuck 2, and can drive the tightening seat 5 to move horizontally. The tightening seat 5 is a plate-like member extending vertically, which is convenient for installing the tightening sleeve 52, and satisfies the rotational coordination effect of the tightening sleeve 52 and the tightening seat 5, so that the tightening sleeve 52 can rotate synchronously with the medicine column 9, thereby ensuring the smoothness of the processing of the medicine column 9.

[0065] On the basis of the above structure, a drill bit 75 is arranged at the driving end of the lead screw drive assembly 7, and is used to drill or expand the medicine column 9. The above drilling or expanding operation can also be arranged before cutting the medicine column 9, that is, drilling or expanding the medicine column 9 first, and then cutting the medicine column 9 according to the length requirement.

[0066] In some embodiments, please refer to Figures 1 to 9The tightening seat 5 is provided with a rotating bearing 53 which is sleeved on the outer periphery of the tightening sleeve 52, and the inner peripheral wall of the tightening sleeve 52 is provided with a matching pin 54 which extends toward the axial center side. The matching pin 54 can move along the external thread of the drill bit 75 driven by the telescopic driving member 51 to remove the chips on the drill bit 75.

[0067] In this embodiment, the provision of the rotating bearing 53 effectively reduces the friction resistance between the top tightening sleeve 52 and the top tightening seat 5, so that the top tightening sleeve 52 can smoothly rotate relative to the top tightening seat 5 to cooperate with the rotation of the drug column 9. The matching pin 54 on the peripheral wall of the top tightening sleeve 52 can move along the external thread of the drill bit 75, and the top tightening sleeve 52 rotates relative to the drill bit 75 under the guidance of the matching pin 54, which meets the requirement of the matching pin 54 to move axially along the drill bit 75, thereby realizing effective removal of chips in the drill bit 75.

[0068] In some embodiments, please refer to Figures 1 to 9 The lead screw drive assembly 7 includes a lead screw 71 rotatably connected to the frame 1 and a nut 72 threadedly connected to the lead screw 71, the lead screw 71 is connected to a rotary drive member 73, a mounting seat 74 is provided above the nut 72, and the telescopic drive member 51 and the drill bit 75 are both mounted on the mounting seat 74;

[0069] Among them, the frame 1 is provided with a proximity sensor 76 located on one side of the screw 71, the proximity sensor 76 is electrically connected to the controller, and the side of the mounting seat 74 is provided with a positioning block 77 extending outward. The proximity sensor 76 is used to monitor the position of the positioning block 77 and generate proximity parameters, and the controller is used to receive the proximity parameters and send control instructions to the rotating drive member 73.

[0070] In this embodiment, the rotating driving member 73 is used to drive the screw 71 to rotate, and the nut 72 drives the mounting seat 74 to move axially along the screw 71, so that the tightening seat 5 can be driven by the mounting seat 74 to approach the medicine column 9, and the tightening sleeve 52 is used to effectively tighten the end surface of the medicine column 9. The tightening sleeve 52 can rotate circumferentially with the medicine column 9 to meet the cutting requirements of the medicine column 9.

[0071] When it is necessary to drill and cut the medicine column 9, the telescopic drive member 51 is first used to drive the tightening seat 5 to move to the side close to the medicine column 9, and then the screw drive assembly 7 is used to drive the mounting seat 74 and the tightening seat 5 to move to the position where the end face of the medicine column 9 needs to be limited, so as to facilitate the axial position of the medicine column 9 to be limited by the tightening sleeve 52.

[0072] Afterwards, the charge column 9 on the loading strip seat 3 is translated through the above-mentioned feeding hole 21 under the action of the push rod 31 until it abuts against the end surface of the top tightening sleeve 52. At this time, the rotating chuck 2 clamps the charge column 9 to lock the axial position of the charge column 9. Then, the top tightening seat 5 follows the retracting of the telescopic driving member 51, and the matching pin 54 on the top tightening sleeve 52 can move along the external thread of the drill bit 75 (at this time, the top tightening sleeve 52 rotates relative to the top tightening seat 5 under the guidance of the matching pin 54), meeting the change requirements of the axial position of the top tightening seat 5 and the drill bit 75. In this process, the matching pin 54 can clean the debris on the outer periphery of the drill bit 75, improve the external cleanliness of the drill bit 75, avoid affecting the drilling size, and ensure the drilling quality of the drill bit 75 on the charge column 9. Finally, the cutting tool 4 is used to move radially along the charge column 9 to achieve the cutting process of the charge column 9, and the charge column falls onto the guide seat 8 and is guided out along the guide seat 8.

[0073] In order to facilitate the control of the moving distance of the screw drive assembly 7, a proximity sensor 76 capable of monitoring the position of the nut 72 is arranged on the frame 1. The proximity sensor 76 is used to monitor the position of the positioning block 77, generate proximity parameters and send them to the controller. The controller can determine whether the position of the mounting seat 74 meets the preset requirements according to the preset program. If the preset requirements are met, the controller sends a control instruction to the rotating drive member 73 to stop driving the rotating drive member 73 to maintain the stability of the positions of each component.

[0074] On the basis of the above structure, a receiving hopper is provided on one side of the frame 1, and a guide seat 8 extending obliquely downward to one side of the receiving hopper is provided on the discharging side of the rotating chuck 2. The guide seat 8 is used to receive the cut medicine column 9 and guide the medicine column 9 to the receiving hopper. The guide seat 8 is used to receive the finished medicine column 9 after cutting, and guide the above medicine column 9 to the receiving hopper for centralized collection. The guide seat 8 is located below the rotating chuck 2, and the two sides of the guide seat 8 have side guards to prevent the medicine column 9 from rolling to both sides, and finally the cut medicine column 9 is smoothly sent to the receiving hopper for centralized collection.

[0075] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
