The belt conveyor 101 and the filling head 104 are installed on the equipment frame 105. The lifting platform 103 is fixedly installed at the bottom of the telescopic cylinder 102 and is slidably connected to the equipment frame 105. The filling head 104 is fixedly installed on the lifting platform 103; The bottle blocking mechanism 2 includes a baffle 201 and a first rotating shaft 202, and the bottle blocking mechanism 2 is mounted on the upper end surface of the transmission mechanism 4; The bottle supporting mechanism 3 comprises a first clamping plate 301, a second clamping plate 302, a material receiving plate 303 and a first transmission device 305, and the bottle supporting mechanism 3 is movably mounted on the upper end surface of the transmission mechanism 4; The transmission mechanism 4 includes a transmission plate 401, a transmission frame 402, an elastic telescopic rod 403, a sleeve 4031, a hanger 404 and a housing 405.

The bottle wiping mechanism 5 is mounted on the first clamping plate 301 and the second clamping plate 302 .

[0021] Furthermore, the baffle 201 is fixedly mounted on the first rotating shaft 202, a torsion spring 2021 is arranged at the bottom of the first rotating shaft 202, the first rotating shaft 202 is mounted on the belt conveyor 101 and is elastically rotatably connected thereto through the torsion spring 2021, a limit rod 1011 is arranged on the belt conveyor 101 for limiting the rotation angle of the baffle 201, and the bottle blocking mechanism 2 is mirror-arranged on the front and rear sides of the belt conveyor 101.

[0022] The first rotating shaft 202 rotates to fit with the limiting rod 1011 when the torsion spring 2021 rotates, so that the baffle 201 stands above the belt conveyor 101 to intercept the medicine bottle so that the bottle supporting mechanism 3 can position it. When the filling is completed, the baffle 201 is driven by the transmission mechanism 4 to rotate outward to release the medicine bottle.

[0023] Furthermore, the first clamping plate 301 and the second clamping plate 302 are mirror-mounted on the front and rear sides of the belt conveyor 101, the first transmission device 305 is fixedly mounted on the upper end surface of the outer shell 405, the front end surface of the first transmission device 305 is provided with a rotatably connected screw rod 3051, the bottom of the first transmission device 305 is provided with a rotatably connected second rotating shaft 3052, the second rotating shaft 3052 and the screw rod 3051 are transmitted through gear meshing in the first transmission device 305, the bottom of the first clamping plate 301 and the second clamping plate 302 is provided with a slider 3011 slidably connected to the upper end surface of the outer shell 405, the slider 3011 passes through the screw rod 3051 and is threadedly connected thereto, and the first clamping plate 301 and the second clamping plate 302 are provided with arc-shaped sleeves 3014 that cooperate with each other.

[0024] By rotating the second rotating shaft 3052, the screw rod 3051 is driven to rotate, so that the slider 3011 drives the first clamping plate 301 and the second clamping plate 302 to move closer to or away from each other under the action of the movement of the screw rod 3051, completing the bottle clamping and releasing actions. After the bottle is clamped and fixed, filling is convenient to prevent the bottle from tipping over during filling or shaking and tilting during the bottle wiping process.

[0025] Furthermore, the outer shell 405 is fixedly mounted on the upper end surface of the belt conveyor 101, the hanger 404 is fixedly mounted on the top lower end surface of the outer shell 405, the transmission frame 402 passes through the hanger 404 and is slidably connected thereto, the elastic telescopic rod 403 is mounted on the side end surface of the casing, the transmission frame 402 is elastically slidably connected to the casing through the elastic telescopic rod 403, a guide plate 4021 is provided on the transmission frame 402, the top of the transmission plate 401 is fixedly mounted on the lifting platform 103, the bottom of the transmission plate 401 passes through the outer shell 405 and is slidably contacted with the upper end surface of the guide plate 4021, the transmission plate 401 is a right-angled trapezoidal plate-like structure, and the bottom of the guide plate 4021 is an inclined surface mechanism that fits the oblique edge of the transmission plate 401.

[0026] When the telescopic cylinder 102 drives the lifting platform 103 to move downward for filling, the transmission mechanism 4 converts the longitudinal displacement of the lifting platform 103 into horizontal displacement through the cooperation of the transmission plate 401 and the transmission frame 402. During the displacement process of the transmission frame 402, the elastic telescopic rod 403 is always squeezed to cause elastic deformation and energy storage. When the lifting platform 103 is reset upward, the transmission frame 402 can also complete the reset under the push of the elastic telescopic rod 403.

[0027] Furthermore, a pulley 4011 is provided at the bottom of the transmission plate 401 , and the elastic telescopic rod 403 includes a sleeve 4031 , a first compression spring 4032 and a slide bar 4033 , and the slide bar 4033 is inserted into the sleeve 4031 and elastically connected thereto via the first compression spring 4032 .

[0028] The pulley 4011 is used to reduce the friction between the transmission plate 401 and the transmission frame 402, thereby improving the smoothness of the transmission process. At the same time, the wear of the transmission plate 401 and the guide plate 4021 is reduced, thereby improving the service life of the equipment. When the elastic telescopic rod 403 contracts, the sliding rod 4033 and the sleeve 4031 squeeze the first compression spring 4032. When the second elastic telescopic rod 403 is reset, the sliding rod 4033 is reset and rebounds under the action of the first compression spring 4032.

[0029] Furthermore, a first gear 2022 rotatably connected via a one-way bearing is provided on the side of the first rotating shaft 202, a second gear 3053 is fixedly installed on the side end face of the second rotating shaft 3052, a rack 4022 cooperating with the first gear 2022 and the second gear 3053 is provided on the transmission frame 402, and the rack 4022 is separated from the first gear 2022 in an initial state.

[0030] When the filling machine body 1 is filling, the telescopic cylinder 102 drives the lifting platform 103 to move downward, and with the cooperation of the transmission plate 401 and the transmission frame 402, drives the rack 4022 to slide to the right. During the sliding process of the rack 4022 to the right, since the first rotating shaft 202 and the first gear 2022 cooperate with each other through the one-way bearing, the first rotating shaft 202 does not rotate. At this time, the baffle 201 is kept at the upper end of the belt conveyor 101 to intercept the medicine bottle under the action of the torsion spring 2021, and the second gear 3053 is fixedly connected with the second rotating shaft 3052, so that the second rotating shaft 3052 is driven to rotate through the cooperation of the rack 4022 and the second gear 3053, and the screw rod 3051 is driven to rotate through the internal gear transmission of the first transmission device 305, so that the first clamping plate 301 and the second clamping plate 302 slide towards each other to clamp the medicine bottle. After filling is completed, the lifting platform 103 is reset, so that the rack 4022 moves to the left. At this time, the rack 4022 can drive the first gear 2022 and the second gear 3053 to rotate, so that the first rotating shaft 202 drives the baffle 201 to flip outward. At the same time, the second rotating shaft 3052 drives the screw rod 3051 to rotate, so that the first clamping plate 301 and the second clamping plate 302 are moved away from each other under the movement of the screw rod 3051, completing the release action of the filled medicine bottle. When the rack 4022 is completely reset, the first gear 2022 is separated from the rack 4022 again, so that the first rotating shaft 202 is reset under the reset action of the torsion spring 2021, and the limit rod 1011 is rotated to continue the interception action.

[0031] Furthermore, the bottle rotating roller 502 is installed on the sliding frame 501 and is rotatably connected thereto. A second transmission device 5012 is provided at the bottom of the sliding frame 501. A mounting groove 5013 is provided at the bottom of the second transmission device 5012. A rotatably connected rotating roller 505 is provided in the mounting groove 5013. The rotating roller 505 and the bottle rotating roller 502 are transmitted through gear meshing. The bottle rotating roller 502 is made of rubber or silicone. The bottle rotating roller 502 is a vertical round roller structure. The rotating roller 505 is a horizontal round roller structure. The axis of the rotating roller 505 is perpendicular to the conveying direction of the belt conveyor 101.

[0032] When the roller 505 contacts the transmission belt on the surface of the belt conveyor 101, the transmission belt drives the roller 505 to rotate, thereby driving the bottle roller 502 to rotate through the second transmission device 5012, and driving the medicine to rotate through the bottle roller 502. During the rotation, the wiping strip 503 wipes the side of the medicine bottle.

[0033] Furthermore, a guide rod 3022 is provided on the second clamping plate 302, and a second compression spring 504 is sleeved on the guide rod 3022. A guide hole 5014 cooperating with the guide rod 3022 is provided on the sliding frame 501. The sliding frame 501 is installed on the guide rod 3022 and is elastically slidably connected to the second clamping plate 302 through the second compression spring 504. A first latch 5011 is provided at the bottom of the sliding frame 501, and a second latch 3013 cooperating with the first latch 5011 is provided on the second clamping plate 302. The upper end surface of the first latch 5011 is a slope structure, and the side surface of the second latch 3013 is a slope structure.

[0034] When the first clamp 301 and the second clamp 302 are clamped, the side of the second pin 3013 squeezes the side of the first pin 5011, causing the sliding frame 501 to squeeze the second compression spring 504 downward to cause longitudinal displacement, so that the roller 505 at the bottom of the sliding frame 501 contacts the transmission belt on the surface of the belt conveyor 101, and the transmission belt drives the roller 505 to rotate under the action of friction, thereby driving the bottle roller 502 to rotate, so that it drives the medicine bottle to rotate under the action of friction, and the side of the medicine bottle is evenly wiped by the wiping strip 503.

[0035] Furthermore, a slide groove 3012 is provided on the first clamping plate 301 , and the wiping strip 503 is inserted into the slide groove 3012 and is slidably connected with the first clamping plate 301 .

[0036] The slidably connected wiping strip 503 is easy to replace, so that it can be removed and replaced after each production is completed, thereby avoiding cross infection caused by residual medicine on the wiping strip 503.

[0037] Furthermore, the receiving plate 303 is fixedly mounted on the upper end surface of the first clamping plate 301 by bolts, and an injection hole 3031 cooperating with the filling head 104 is provided on the receiving plate 303, an annular flange 3033 is provided on the edge of the upper end surface of the receiving plate 303, and a medicine discharge hole 3032 is provided at the bottom of the receiving plate 303.

[0038] When the first clamping plate 301 and the second clamping plate 302 are clamped, the injection hole 3031 on the receiving plate 303 is aligned with the filling head 104, so that the filling head 104 can fill the medicine bottle. When the first clamping plate 301 and the second clamping plate 302 are separated, the injection hole 3031 and the filling head 104 are misaligned, so that the residual medicine dripping from the filling head 104 drips onto the receiving plate 303. After production is completed, the receiving plate 303 is disassembled for cleaning.

[0039] When the device is in use, the medicine bottle enters the belt conveyor 101 intermittently and equidistantly through the medication device at the front end, and is fed into the device through the belt conveyor 101. When the medicine bottle reaches the predetermined position, the first rotating shaft 202, under the action of the torsion spring 2021, makes the baffle 201 stand above the belt conveyor 101 to intercept the medicine bottle. After being intercepted by the baffle 201, the medicine bottle stays at the predetermined position of the belt conveyor 101, waiting for the bottle supporting mechanism 3 to perform the next operation. The telescopic cylinder 102 drives the lifting platform 103 to move downward, and the filling head 104 descends to the position of the medicine bottle mouth. When When the telescopic cylinder 102 drives the lifting platform 103 to move downward, the transmission mechanism 4 converts the longitudinal displacement into horizontal displacement through the cooperation of the transmission plate 401 and the transmission frame 402, so that the transmission frame 402 squeezes the elastic telescopic rod 403, elastic deformation occurs to store energy, and drives the rack 4022 to slide to the right. During the right sliding process of the rack 4022, the first rotating shaft 202 does not rotate because the first rotating shaft 202 and the first gear 2022 cooperate to drive through the one-way bearing. At this time, the baffle 201 is kept on the upper side of the belt conveyor 101 by the action of the torsion spring 2021. The medicine bottle is intercepted at the end, and the second gear 3053 is fixedly connected with the second rotating shaft, so that the second rotating shaft 3052 is driven to rotate through the cooperation of the rack 4022 and the second gear 3053, and the screw rod 3051 is driven to rotate through the internal gear of the first transmission device 305, so that the first clamping plate 301 and the second clamping plate 302 slide towards each other, clamping the medicine bottle to ensure that it will not shake or tip over during the filling process, thereby improving the stability of the filling, and starting to fill the liquid medicine, the filling head 104 is aligned with the mouth of the medicine bottle through the injection hole 3031 on the receiving plate 303 to ensure that the liquid medicine is accurately injected into the medicine bottle. After the filling is completed, the telescopic cylinder 102 drives the lifting platform 103 to reset upward, and the transmission frame 402 is also reset under the push of the elastic telescopic rod 403, and the rack 4022 moves to the left, driving the first gear 2022 and the second gear 3053 to rotate, and the first rotating shaft 202 drives the baffle 201 to flip outward, and the second rotating shaft 3052 drives the screw rod 3051 to rotate in the opposite direction, and the second rotating shaft 3052 drives the screw rod 3051 to rotate in the opposite direction, so that the first splint 301 and the second splint 302 move away from each other, loosening the medicine bottle, and the medicine bottle is released and continues to move along the belt conveyor 101.

[0040] During filling, after the medicine bottle is clamped and fixed, the roller 505 at the bottom of the sliding frame 501 contacts the transmission belt on the surface of the belt conveyor 101, and the transmission belt drives the roller 505 to rotate, and then drives the bottle rotating roller 502 to rotate through the second transmission device 5012. During the rotation process, the bottle rotating roller 502 drives the medicine bottle to rotate by friction, and the wiping strip 503 evenly wipes the side of the medicine bottle to remove stains or residual medicine on the surface of the medicine bottle.

[0041] 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.
