Description

Technical Field

[0001] This invention relates to the field of filling technology, and in particular to a filling device for the production of veterinary drops. Background Technology

[0002] Veterinary drops are typically produced using rotary filling machines. Existing rotary filling machines generally include an intermittently rotating disc with a feeding slot. The drop bottles are placed in the slot and rotate with the disc. The disc houses a filling device, a vibrator for cap feeding, and a screwing device. After the disc rotates to position the drop bottles below these devices, the filling and screwing devices move downwards, placing the filling head and screwing sleeve onto the drop bottles for filling and screwing operations. Because the filling device, screwing device, and disc are all controlled by independent drive units, accurate filling and screwing cannot be guaranteed if the disc's rotation angle is misaligned. Furthermore, it cannot be guaranteed that the dropper bottle will rotate within the slot. The slot size is usually the same as the outer diameter of the dropper bottle, and the significant friction between them prevents the bottle from rotating when the cap is screwed on. However, with prolonged use, wear on the inner wall of the slot increases the inner diameter and smooths the surface, reducing friction and causing the dropper bottle to wobble within the slot. This can lead to the bottle rotating along with the cap when it is screwed on, resulting in incomplete screwing. Therefore, we have designed a filling device for veterinary dropper production. Summary of the Invention

The rotating tray includes two turntables fixed on a rotating shaft. Multiple evenly distributed material-clamping notches are provided on the edge of the turntables, and the material-clamping notches on the upper and lower turntables correspond one to one.

The rotating rod is connected to a screwing sleeve via a toothed belt and a toothed pulley. The inner ring of the connecting sleeve has multiple limiting grooves arranged in a ring array. A pressing rod is rotatably mounted on the inner ring of the connecting sleeve via a bearing. The upper end of the pressing rod is placed on the outer ring surface of the inner ring portion of the connecting sleeve, which has multiple ring-arranged moving cavities. A driving rod is slidably mounted in the moving cavity. An anti-contact spring is provided in the moving cavity. The two ends of the anti-contact spring abut against the driving rod and the inner wall of the moving cavity, respectively. A bidirectional threaded sleeve is vertically fixed above the frame. A bidirectional threaded rod is internally threaded onto the bidirectional threaded sleeve. The top of the bidirectional threaded rod has an insertion hole. A pressing sliding hole is formed through the outer ring surface of the bidirectional threaded rod. The lower end of the pressing rod is slidably inserted into the insertion hole.

An offset slope is formed by removing part of the offset plate near the offset cylinder. The slope of the offset slope is the same as the slope of the pushing slope.

The depth of the deflection channel gradually decreases from top to bottom, and the depth of the top of the deflection channel is the same as the depth of the reversing channel. The depth of the vertical channel is greater than the depth of the bottom of the deflection channel. The number of deflection channels and vertical channels is the same as the number of jamming notches and deflection structures.

[0014] The beneficial effects of this invention are: 1. By setting a feeding mechanism on the frame, and the feeding mechanism is equipped with a filling mechanism, a vibrator and a screwing mechanism, the filling mechanism, the screwing mechanism and the feeding mechanism are all connected to the drive mechanism. After the feeding mechanism deflects the drop bottle above it into place, the filling mechanism and the rotating mechanism can move down and perform filling and screwing operations. This ensures that the drop bottle and the cap are accurately positioned directly below the filling mechanism and the screwing mechanism, improving the accuracy of filling and screwing and avoiding filling and screwing errors caused by the asynchrony between the filling mechanism, the screwing mechanism and the feeding mechanism. 2. By setting a clamping structure at the screwing position of the feeding mechanism, the dropper bottle can be positioned to prevent it from shaking when screwed. In conjunction with the set drive mechanism and screwing mechanism, the screwing mechanism can only screw after the dropper bottle is in the designated position and the clamping structure clamps and positions the dropper bottle. This prevents the bottle cap from rotating when screwing on, thus improving the firmness of the bottle cap knob. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0018] Reference Figures 1-10 A veterinary drop production filling equipment includes a frame 1, a feeding mechanism 4 installed above the frame 1, an infeed conveyor belt 2 installed on the left side of the feeding mechanism 4, an outfeed conveyor belt 3 installed in front of the feeding mechanism 4, multiple drop bottles placed on the infeed conveyor belt 2, a filling mechanism 5 for filling installed in a lifting manner at the left rear of the feeding mechanism 4, a vibrator 6 for cap feeding installed on the upper right side of the frame 1, a vibrating track 61 provided at the outlet of the vibrator 6, the other end of the vibrating track 61 being above the feeding mechanism 4, a screwing mechanism 7 for tightening caps installed in a lifting manner on the right side of the feeding mechanism 4, and a drive mechanism 8 for lifting the filling mechanism 5 and the screwing mechanism 7 installed below the frame 1, the drive mechanism 8 also being connected to the feeding mechanism 4.

[0019] Reference Figure 4 , Figure 5 The feeding mechanism 4 includes a baffle 41 fixed above the frame 1 by a bracket. A rotating material plate 42 is rotatably mounted on the inner ring of the baffle 41. A rotating shaft 45 is fixed at the lower end of the rotating material plate 42. The rotating shaft 45 is rotatably connected to the frame 1 through a bearing, and the lower end of the rotating shaft 45 passes through the frame 1 and is positioned below it. An intermittent rotating sleeve 43 is installed at the lower end of the rotating shaft 45. The intermittent rotating sleeve 43 is connected to the drive mechanism 8. A clamping structure 44 for fixing the dropper bottle is also installed on the side of the baffle 41.

[0020] The baffle 41 includes a support ring 411 fixed above the frame 1 by a bracket. A side baffle ring 412 is suspended above the support ring 411 by a support column. The inner diameter of the side baffle ring 412 is larger than the inner diameter of the support ring 411. Both the support ring 411 and the side baffle ring 412 have portions cut off to form openings. These openings are used for the dropper bottle to enter into the feeding mechanism 4 and to flow out of the feeding mechanism 4. The rotating tray 42 includes two turntables 421 fixed on the rotating shaft. Multiple evenly distributed material-clamping notches 422 are provided on the edge of the turntables 421, and the material-clamping notches 422 on the upper and lower turntables 421 correspond one to one. The outlet of the oscillating track 61 is located directly above one of the material-clamping notches 422. When the dropper bottle passes through this position, the bottle cap in the oscillating track 61 can be pressed against the bottle mouth of the dropper bottle. The size of the material-clamping notch 422 is the same as the outer diameter of the dropper bottle, and the outer diameter of the turntable 421 is the same as the inner diameter of the side retaining ring 412. The outer diameter of the turntable 421 is smaller than the outer diameter of the support ring 411, and the outer diameter of the turntable 421 is larger than the inner diameter of the support ring 411. The dropper bottle can be clamped into the material-clamping notch 422 and rotate together with the rotating material tray 42. The lower end of the dropper bottle can be positioned above the support ring 411 to support the dropper bottle and allow it to move along the top of the support ring 411.

[0021] Reference Figure 5 , Figure 6 The clamping structure 44 includes a side frame 441 screwed to the outer surface of the side retaining ring 412. The side frame 412 is located below the screwing mechanism 7 and is directly opposite the material clamping notch 422 located below the screwing mechanism 7. The side frame 441 has two round holes located between the side retaining ring 412 and the support ring 411. An abutment rod 442 is slidably inserted into the round holes. An abutment plate 443 is fixed between the left ends of the two abutment rods 442. An offset plate 445 is fixed to the right end of the abutment rods 442. An abutment spring 444 is sleeved on the abutment rods 442. The two ends of the abutment spring 444 abut against the offset plate 445 and the side frame 441, respectively. The abutment plate 443 is located between the side retaining ring 412 and the support ring 411. The upper part of the abutment plate 443... The surface of the abutment plate 443 slides in contact with the lower surface of the side retaining ring 412. When the abutment plate 443 is not squeezed inward by external force, there is a certain gap between the inner side surface of the abutment plate 443 and the inner side wall of the side retaining ring 412. The inner side surface of the abutment plate 443 is provided with a rubber pad, which has a certain elasticity and can avoid crushing the dropper bottle when in contact with it. When the offset plate 445 is squeezed by external force, it can move to the left, thereby causing the abutment plate 443 to move to the left as well. The inner wall of the abutment plate 443 that moves to the left can contact the outer wall of the dropper bottle, thereby clamping it between the material notch 422 and the abutment plate 443, thus fixing it and increasing the resistance, so that it will not rotate when the bottle cap is screwed on, thus improving the firmness of the bottle cap knob.

[0022] Reference Figure 2 , Figure 4 as well as Figure 7 The filling mechanism 5 includes a lifting sleeve 511 fixed on the frame 1. A lifting rod 51 is slidably inserted into the lifting sleeve 511. A lifting frame 52 is installed above the lifting rod 51. A filling head 53 is installed on the lifting frame 52. A solenoid valve 54 is installed at the top of the filling head 53. The bottom end of the lifting rod 51 is connected to the drive mechanism 8. The inlet of the solenoid valve 54 is connected to an external peristaltic pump through a hose. The peristaltic pump is connected to a container containing medicine through a pipe. The axis of the filling head 53 is collinear with the axis of one of the material notches 422. The filling head 53 can extend into the dropper bottle, thereby filling the liquid into the dropper bottle. A fixed ring is fixed on the lifting rod 51. A lifting ring 56 is connected to the lower part of the fixed ring by a spring. The lifting ring 56 slides up and down to fit the outer ring of the lifting rod 51. A lower electrode 561 is set below the lifting ring 56. A contact ring 55 is set on the lifting sleeve 511. An upper electrode 551 is set on the contact ring 55. The lower electrode 561 is connected to the solenoid valve 54 through a circuit. The upper electrode 551 is connected to an external power supply. When the lifting rod 51 moves downward, the lower electrode 561 on the lifting ring 56 can contact the upper electrode 551, thereby turning on the power supply of the solenoid valve 54 and allowing the liquid in the filling head 53 to flow out.

[0023] Reference Figure 2 , Figure 4 The screwing mechanism 7 includes a guide sleeve 711 fixed on the frame 1. A lifting column 71 is slidably inserted into the guide sleeve 711. The bottom end of the lifting column 71 is connected to the drive mechanism 8. A fixed frame 72 is installed above the lifting column 71. A rotating structure 74 and a screwing sleeve 73 are installed on the fixed frame 72. A bidirectional screw sleeve 76 for driving the rotating structure 74 is fixed on the top of the frame 1. The screwing sleeve 73 is located directly above one of the material clamping notches 422. An offset cylinder 75 for driving the clamping structure 44 is installed on the lifting column 71. The lifting column 71 can move up and down under the action of the drive mechanism 8, so that the screwing sleeve 73 is inserted into the bottle cap. The rotating structure 74 can rotate the screwing sleeve 73 through the belt, so that the bottle cap is screwed onto the drop bottle.

[0024] Reference Figure 8 , Figure 9 The rotating structure 74 includes a connecting sleeve 742 rotatably mounted on a fixed frame 72 via bearings. A rotating rod 741 is fixed to the top of the connecting sleeve 742. The rotating rod 741 is connected to a screwing sleeve 73 via a toothed belt and a toothed pulley. The inner ring of the connecting sleeve 742 has multiple limiting grooves 744 arranged in a ring array. A pressing rod 743 is rotatably mounted on the inner ring of the connecting sleeve 742 via bearings. The upper end of the pressing rod 743 is located on the outer ring surface of the inner ring portion of the connecting sleeve 742, which has multiple ring-arc ... 45. An abutment spring 746 is provided inside the moving cavity. The two ends of the abutment spring 746 abut against the drive rod 745 and the inner wall of the moving cavity, respectively. A bidirectional threaded sleeve 76 is vertically fixed above the frame 1. A bidirectional screw 761 is connected to the internal thread of the bidirectional threaded sleeve 76. The top end of the bidirectional screw 761 is provided with a insertion hole. The outer ring surface of the bidirectional screw 761 is designed to form a downward sliding hole 762. The lower end of the downward pressing rod 743 is slidably inserted into the insertion hole. A slider is provided below the outer ring surface of the downward pressing rod 743. The slider is slidably placed in the downward sliding hole 762. One end of the limiting groove 744 is provided with a stepped surface with a vertical structure on the inner ring of the connecting sleeve 742, and the other end of the limiting groove 744 is connected to the inner ring of the connecting sleeve 742 through an arc-shaped inclined surface. The drive rod 745 always has the tendency to move outward under the action of the abutment spring 746, so that the outer side of the drive rod 745 contacts the inner ring of the connecting sleeve 742 or the limiting groove 744. The outer ring of the connecting sleeve 742 is also provided with a fixed sleeve, and the two are rotatably connected. A bolt is threaded on the fixed sleeve, which is used to adjust the resistance between the connecting sleeve 742 and the fixed sleeve. When the downward-facing pressure rod 743 causes the slider to contact the bottom end of the downward-facing sliding hole 762 of the bidirectional screw 761, the pressure rod 743 will push the bidirectional screw 761 downwards. Because the self-locking effect between the bidirectional screw 761 and the bidirectional sleeve 76 is extremely poor, the bidirectional sleeve 76 is fixed and cannot rotate. Therefore, the bidirectional screw 761 will rotate clockwise during its downward movement. This clockwise rotation of the bidirectional screw 761 will drive the pressure rod 743 to rotate clockwise as well. During this clockwise rotation, the driving... The outer end of rod 745 will contact the stepped surface of limiting groove 744 and push connecting sleeve 742, rotating rod 741 and screwing sleeve 73 to rotate together. When the bidirectional screw 761 moves upward and rotates counterclockwise, the frictional resistance between driving rod 745 and arc surface is less than the resistance between connecting sleeve 742 and fixed sleeve. Driving rod 745 will slide along arc surface and retract into moving cavity, so that connecting sleeve 742 will not rotate, and therefore screwing sleeve 73 will not rotate with it.

[0025] Reference Figure 6 An offset block 751 is provided on the side of the offset cylinder 75 near the offset plate 445. A pushing inclined surface 752 is formed by removing a portion of the offset block 751 away from the offset cylinder 75. An offset inclined surface 446 is formed on the side of the offset plate 445 near the offset cylinder 75, and the slope of the offset inclined surface 446 is the same as the slope of the pushing inclined surface 752. The lower half of the offset plate 445 is vertically positioned above the frame 1. When the offset cylinder 75 moves downwards along with the lifting column 71, the pushing inclined surface 752 can... When the offset ramp 446 contacts the offset plate 445 and pushes it away from the offset cylinder 75, the abutment plate 443 approaches the dropper bottle, and the inner wall of the abutment plate 443 contacts the outer wall of the dropper bottle, thereby clamping it between the material notch 422 and the abutment plate 443, thus fixing it and increasing resistance, so that it will not rotate when the bottle cap is screwed on, improving the firmness of the bottle cap knob. When the ramp 752 contacts the lower half of the offset plate 445, the abutment plate 443 will not move.

[0026] Reference Figure 4 , Figure 10The drive mechanism 8 includes a mounting plate fixed below the frame 1. Two cylinders 81 are mounted on the mounting plate. A lifting plate 82 is mounted on the push rod of the cylinder 81. The lifting plate 82 has a round opening. The lifting plate 82 is sleeved on the intermittent rotating sleeve 43 through the round opening. Multiple deflection structures 83 are arranged in a ring on the lifting plate 82. The deflection structures 83 are slidably connected to the intermittent rotating sleeve 43. The bottom ends of the lifting column 71 and the lifting rod 51 are fixed to the lifting plate 82.

[0027] The deflection structure 83 includes a fixed seat 831 fixed on the lifting plate 82, a deflection rod 832 slidably inserted on the fixed seat 831, a pressure plate 834 fixed on the inward side of the deflection rod 832, and a pressure spring 833 sleeved on the deflection rod 832. The two ends of the pressure spring 833 abut against the pressure plate 834 and the fixed seat 831 respectively. The outer ring of the intermittent rotating sleeve 43 is provided with a deflection groove. The deflection rod 832 is slidably placed in the deflection groove at its inward end. The deflection groove includes multiple deflection slide grooves 432 distributed in a ring. Every two adjacent deflection slide grooves 432 are connected by a vertical slide groove 431. The upper end of the vertical slide groove 431 is connected to the upper end of the deflection slide groove 432. The upper end of the vertical slide groove 431 is deepened to form a reversing groove 433. The lower end of the deflection slide groove 432 is connected to the lower part of the vertical slide groove 431. The lower extension of the vertical slide groove 431 is located below the deflection slide groove 432. The depth of the deflection slide groove 432 gradually decreases from top to bottom. The top depth of the deflection slide groove 432 is the same as the depth of the reversing groove 433. The depth of the vertical slide groove 431 is greater than the bottom depth of the deflection slide groove 432. The number of deflection chute 432 and vertical chute 431 is the same as the number of material jamming notch 422 and deflection structure 83. The top view projection of the deflection chute 432 is an arc structure. The arc length of the arc structure is 1 / n of the circumference of the intermittent rotating sleeve 43, where n is the number of material jamming notches 422. When the deflecting rod 832 moves a complete path within the deflection groove 432, the entire intermittent rotating sleeve 43 will rotate 1 / n revolutions, that is, the jamming notch 422 will rotate one unit distance. When the deflecting rod 832 is in the vertical groove 431, the entire intermittent rotating sleeve 43 will not rotate. When the deflecting rod 832 is at the top, it will be in the reversing groove 433. When the deflecting rod 832 moves downward again, it will be in the deflection groove 432, causing the intermittent rotating sleeve 43 to rotate again.

[0028] Working principle: In actual use, the dropper bottle is on the feeding conveyor belt 2 and moves to the right under the action of the feeding conveyor belt 2. The dropper bottle at the rightmost end will contact the outer ring surface of the turntable 421 and has a tendency to move to the right. Part of the dropper bottle is within the material-holding notch 422 of the turntable 421 (within the range of...). Figure 1(As shown in the example), then the push rod of cylinder 81 moves downward. When the push rod of cylinder 81 moves downward, it will cause the lifting plate 82 and the deflection structure 83 to move downward together. When the push rod of cylinder 81 is at its maximum stroke, that is, when the filling head 53 and the screw sleeve 73 are at their highest positions, the deflection rod 832 is in the reversing groove 433. Since the top depth of the deflection groove 432 is the same as the depth of the reversing groove 433, and the depth of the vertical groove 431 is less than the top depth of the deflection groove 432, when the lifting plate 82 moves the deflection rod 832 downward under the action of cylinder 81, the deflection rod 832 will move along the deflection groove 432. When the deflection rod 832 moves along the inside of the deflection groove 432, it will cause the intermittent rotating sleeve 43 to rotate 1 / n turns (n ​​is the number of material jamming notches 422). At this time, a new drop bottle will be placed in the empty material jamming notch 422, and the drop bottle will be directly below the filling head 53. The filled drop bottle will be below the discharge port of the oscillating track 61, and the drop bottle with the cap will move directly below the screw sleeve 73. After the notch 422 causes the dropper bottle to deflect by a unit distance, the deflecting rod 832 is now in the vertical groove 431, and there is still some space below the vertical groove 431. At this time, the push rod of the cylinder 81 can continue to move downward. The lifting plate 82 causes the lifting column 71 and the lifting rod 51 to continue to move downward, pushing the inclined surface 752 to contact the offset inclined surface 446 and pushing the offset plate 445 away from the offset cylinder 75, so that the abutment plate 443 is close to the dropper bottle, and the inner wall of the abutment plate 443 can contact the outer wall of the dropper bottle, thereby clamping the dropper bottle between the notch 422 and the abutment plate 443, thus fixing it and increasing the resistance, so that it will not rotate when the cap is screwed on, thus improving the firmness of the cap knob. When the inclined plane 752 contacts the lower half of the offset plate 445, the abutment plate 443 will not move. The slider on the pressing rod 743 contacts the bottom end of the pressing sliding hole 762 of the bidirectional screw 761. Due to the poor self-locking effect between the bidirectional screw 761 and the bidirectional screw sleeve 76, the bidirectional screw 761 will rotate clockwise during the downward movement. The outer end of the driving rod 745 will contact the stepped surface of the limiting groove 744 and push the connecting sleeve 742 and the rotating rod 741 to rotate. The screwing sleeve 73 will rotate together with the rotating rod 741 under the action of the toothed belt and toothed pulley, so that the bottle cap is screwed onto the drop bottle. At this time, the filling head 53 extends into the dropper bottle, and the lower electrode 561 on the lifting ring 56 contacts the upper electrode 551, thereby turning on the power to the solenoid valve 54, allowing the liquid in the filling head 53 to flow out. The lifting ring 56 can slide up and down under the action of the spring, and it can ensure that the lower electrode 561 contacts the upper electrode 551. The power to the solenoid valve 54 is turned on, and the peristaltic pump can make the medicine fill into the dropper bottle through the solenoid valve 54 and the filling head 53.

[0029] When the push rod of cylinder 81 extends and causes the lifting plate 82 to move upward, the pressing rod 743 will also move upward. When the slider on the pressing rod 743 contacts the top of the pressing slide hole 762, the bidirectional screw 761 will move upward and rotate counterclockwise. The frictional resistance between the drive rod 745 and the arc surface is less than the resistance between the connecting sleeve 742 and the fixed sleeve. The drive rod 745 will slide along the arc surface and retract into the moving cavity, so that the connecting sleeve 742 will not rotate. Therefore, the screwing sleeve 73 will not rotate either. When the push rod of cylinder 81 extends to a certain extent, the upper electrode 551 and the lower electrode 561 disengage, the filling of the dropper bottle is completed and the filling stops, the inclined surface 752 is pushed to disengage from the deflection inclined surface 446, and the abutment plate 443 moves away from the dropper bottle under the action of the abutment spring 444, thereby releasing the fixation of the dropper bottle. Since the depth of the vertical slide groove 431 is greater than the depth of the bottom of the deflection slide groove 432, the deflection rod 832 will move along the vertical slide groove 431 and move into the reversing groove 433 when it moves upward. When it moves down again, the deflection rod 832 will move along the deflection groove 432 again, causing the rotating material tray 42 to rotate 1 / n revolution. All the drop bottles will move together, and the twisted drop bottles will move onto the discharge conveyor belt 3. The empty material gap 422 will also be filled with drop bottles. This cycle repeats continuously, so that feeding, filling, capping, screwing on, and discharging can be performed continuously.

[0030] By setting a feeding mechanism 4 on the frame 1, and the feeding mechanism 4 is equipped with a filling mechanism 5, a vibrator 6 and a screwing mechanism 7, wherein the filling mechanism 5, the screwing mechanism 7 and the feeding mechanism 4 are all connected to the drive mechanism 8, the feeding mechanism 4 deflects the drop bottle above it into position, and the filling mechanism 5 and the screwing mechanism 7 can then perform filling and screwing operations, so that the drop bottle and the bottle cap can be accurately positioned directly below the filling mechanism 5 and the screwing mechanism 7, thereby improving the accuracy of filling and screwing and avoiding filling and screwing errors caused by the asynchrony between the filling mechanism 5 and the screwing mechanism 7 and the feeding mechanism 4; By setting a clamping structure 44 at the screwing position of the feeding mechanism 4, the dropper bottle can be positioned to prevent it from shaking when screwed. In conjunction with the set drive mechanism 8 and screwing mechanism 7, the screwing mechanism 7 can only screw after the dropper bottle is in the designated position and the clamping structure 44 clamps and positions the dropper bottle. This prevents the bottle cap from rotating when screwed on, thus improving the stability of the bottle cap knob.
