Description

Technical Field

[0001] The utility model relates to the technical field of medicine production equipment, in particular to a PP bottle oral liquid bottle feeding device. Background Art

[0002] In the pharmaceutical and medical industries, oral liquid bottles play a vital role as packaging containers for liquid medicines. PP (polypropylene) is widely used in the production of oral liquid bottles due to its excellent biocompatibility, chemical resistance, lightweight design, and good sealing properties.

[0003] Traditionally, oral liquid bottles were fed using a screw feeder to feed and distance them, while plastic bottles with rims were fed using air delivery. However, small PP oral liquid bottles, due to their small diameter and high height, have a high center of gravity, making a screw feeder impractical. Furthermore, the small rim of the bottle mouth prevents air delivery with a clamped bottle mouth. Therefore, a multi-row stacking system was introduced, with a large dial directly driving the bottles into the filling machine. This provides stable support for the small PP oral liquid bottles and prevents them from tipping over due to their high center of gravity. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the existing small PP oral liquid bottles, such as small diameter, high height and high center of gravity, and the conventional conveying method that makes the bottle more likely to fall over, and to propose a PP bottle oral liquid bottle feeding device.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A PP bottle oral liquid bottle feeding device includes a multi-row buffer chain network conveyor platform and a large-size dial. The large-size dial is arranged at the outlet end of the multi-row buffer chain network conveyor platform. The outer wall of one side of the multi-row buffer chain network conveyor platform is fixedly connected to a fixed frame. A multi-stage hydraulic cylinder is provided on the fixed frame. The telescopic end of the multi-stage hydraulic cylinder is connected to an extrusion plate. The outer wall of the other side of the multi-row buffer chain network conveyor platform is fixedly connected to a first motor. The first motor is connected to the fixed plate through a straightening structure that can push the oral liquid bottles to move.

[0007] Preferably, oblique guide blocks are provided on both sides of the inner wall of the outlet end of the multi-row buffer chain network conveyor platform.

[0008] Preferably, an inner groove is provided on the inner wall of one side of the multi-row buffer chain network conveyor platform, a through opening is provided on the inner wall of the inner groove, a connecting block is provided on the inner wall of the fixed frame, and a fixing block is provided on the outer wall of the extrusion plate.

[0009] Preferably, the inner wall of one end of the inner slide groove is rotatably connected to one end of the extrusion plate, the multi-stage hydraulic cylinder is rotatably connected to the connecting block, the telescopic end of the multi-stage hydraulic cylinder is rotatably connected to the fixed block, and the multi-stage hydraulic cylinder is arranged in the through opening.

[0010] Preferably, the straightening structure includes an outer slide groove, a lead screw, a slider, a sliding mouth, a flip rod, a second motor, and a soft pad. The outer slide groove is arranged on the outer wall of the other side of the multi-row buffer chain conveyor platform. The lead screw is rotatably connected to the inner wall of the outer slide groove, the slider is slidably connected to the outer slide groove, and the slider is threadedly connected to the lead screw.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

The righting structure can also allow the fixed plate to push the oral liquid bottles from the rear all the time, making the bottle feeding smoother and further reducing the probability of the bottles falling over.

DETAILED DESCRIPTION

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0020] Reference Figure 1-Figure 4 A PP bottle oral liquid bottle feeding device includes a multi-row buffer chain network conveyor platform 1 and a large-size dial 2. The large-size dial 2 is arranged at the outlet end of the multi-row buffer chain network conveyor platform 1. A fixed frame 3 is fixedly connected to the outer wall of one side of the multi-row buffer chain network conveyor platform 1. A multi-stage hydraulic cylinder 4 is provided on the fixed frame 3. The telescopic end of the multi-stage hydraulic cylinder 4 is connected to an extrusion plate 5. The outer wall of the other side of the multi-row buffer chain network conveyor platform 1 is fixedly connected to a first motor 6. The first motor 6 is connected to a fixed plate 7 through a righting structure that can push the oral liquid bottle to move.

[0021] The system uses multiple rows of buffer chains instead of the original single-row chain, which reduces the speed of bottles and allows them to accumulate to prevent empty bottles from falling over. A large dial is used to move the bottles along the multiple-row buffer chains and bring them into the filling machine's dial for washing, filling, and sealing.

[0022] It should be noted that the multi-row buffer chain conveyor platform 1 and the large-size dial 2, the multi-stage hydraulic cylinder 4, the first motor 6, and the second motor 18 are existing technologies. The specific model specifications need to be selected and determined based on the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be repeated.

[0023] Furthermore, oblique guide blocks 8 are provided on both sides of the inner wall of the outlet end of the multi-row buffer chain network conveyor platform 1 .

[0024] Among them, through the oblique guide block 8, the oral liquid bottles can be concentrated in one position to contact the large-size dial 2.

[0025] Furthermore, an inner slide groove 9 is opened on the inner wall of one side of the multi-row buffer chain network conveyor platform 1, a through opening 10 is opened on the inner wall of the inner slide groove 9, a connecting block 11 is set on the inner wall of the fixed frame 3, and a fixing block 12 is set on the outer wall of the extrusion plate 5.

[0026] Among them, by starting the multi-stage hydraulic cylinder 4, the extrusion plate 5 can be pushed to leave the inner slide 9. Under the premise that the extrusion plate 5 and one end of the inner slide 9 are rotatably connected, the extrusion plate 5 can be rotated 90 degrees and push the oral liquid bottles accumulated here forward, making the gap between the bottles smaller, greatly reducing the probability of bottle overturning.

[0027] Furthermore, the inner wall of one end of the inner slide groove 9 is rotatably connected to one end of the extrusion plate 5, the multi-stage hydraulic cylinder 4 is rotatably connected to the connecting block 11, the telescopic end of the multi-stage hydraulic cylinder 4 is rotatably connected to the fixed block 12, and the multi-stage hydraulic cylinder 4 is arranged in the through port 10.

[0028] The length of the multi-stage hydraulic cylinder 4 after full contraction is exactly the same as the length of the fixing frame 3 plus the through opening 10, so that the extrusion plate 5 can completely enter the inner chute 9 without affecting the transportation of the oral liquid bottle.

[0029] Furthermore, the straightening structure includes an outer slide 13, a screw 14, a slider 15, a slide 16, a flip rod 17, a second motor 18, and a soft pad 19. The outer slide 13 is arranged on the outer wall on the other side of the multi-row buffer chain conveyor platform 1. The screw 14 is rotatably connected to the inner wall of the outer slide 13, the slider 15 is slidably connected to the outer slide 13, and the slider 15 is threadedly connected to the screw 14.

[0030] Among them, the righting structure is achieved by starting the second motor 18, which drives the flip rod 17 to rotate to the right until the fixed plate 7 is against the top of the multi-row buffer chain conveyor platform 1, and then starts the first motor 6, which drives the lead screw 14 to rotate, and the lead screw 14 drives the slider 15 to move back and forth on the outer slide 13, and the slider 15 drives the flip rod 17 to move back and forth, and the flip rod 17 drives the fixed plate 7 to move, and the fixed plate 7 pushes the oral liquid bottle forward.

[0031] Furthermore, the sliding opening 16 is provided at the top end of the slider 15 , the flip rod 17 is rotationally connected to the sliding opening 16 , the second motor 18 is fixedly connected to the outer wall of the slider 15 , and the cushion 19 is fixedly connected to the outer wall of the fixing plate 7 .

[0032] Among them, the output end of the first motor 6 passes through the outer wall of the multi-row buffer chain conveyor platform 1 and is fixedly connected to the screw 14; the output end of the second motor 18 passes through the outer wall of the slider 15 and is connected to the outer wall of the flip rod 17.

[0033] Working principle: When the device is in use, the multi-row buffer chain network conveyor platform 1 conveys the oral liquid bottles to the large-size dial 2, and most of the oral liquid bottles are accumulated at the outlet of the multi-row buffer chain network conveyor platform 1, and then the multi-stage hydraulic cylinder 4 is started to push the extrusion plate 5 to leave the inner slide 9. Under the premise that the extrusion plate 5 and one end of the inner slide 9 are rotatably connected, the extrusion plate 5 can be rotated 90 degrees and push the oral liquid bottles accumulated here forward, so that the gap between the bottles is smaller, which greatly reduces the probability of bottle overturning. Faced with the decrease in oral liquid bottles, the extrusion plate 5 cannot play a role. At this time, the second motor 18 can be started, and the second motor 18 drives the flip rod 17 to rotate to the right until the fixed plate 7 is against the top of the multi-row buffer chain network conveyor platform 1, and then the first motor 6 is started, the first motor 6 drives the lead screw 14 to rotate, and the lead screw 14 drives the slider 15 to move back and forth on the outer slide 13, the slider 15 drives the flip rod 17 to move back and forth, the flip rod 17 drives the fixed plate 7 to move, and the fixed plate 7 pushes the oral liquid bottles forward.

[0034] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
