Description

Technical Field

[0001] The utility model relates to the field of oral liquid production, in particular to a liquid level detection and screening integrated device for oral liquid. Background Art

[0002] After the oral liquid bottles are filled with liquid, it is necessary to check whether the liquid level meets the standard, and then cap and box them to avoid the problem of empty bottles or half bottles of liquid being packaged and sold. Liquid level detection can be done by random inspection and full inspection. The random inspection method is to divert part of the oral liquid on the transmission line to another transmission line at regular intervals and detect the liquid level. If no unqualified products are detected, the products of this batch are deemed qualified. If the liquid level does not meet the standard, the previous batch that has been boxed is manually inspected. The random inspection method is more suitable for production lines with a known high pass rate, which can save hardware and labor costs. However, for production lines with low or unstable pass rates, it is easy to miss inspections, which increases the time cost of subsequent manual identification. Utility Model Content

DETAILED DESCRIPTION

[0020] like Figure 1-5 In the invention, a liquid level detection and screening integrated device for oral liquid comprises a first conveyor belt 3, a medicine bottle feeding assembly 1 and a feeding screw 2 are respectively arranged on both sides of one end of the first conveyor belt 3, a shooting device 4 and a light board 5 are respectively arranged on both sides of the other end of the first conveyor belt 3, a second conveyor belt 6 is also arranged on one side of the first conveyor belt 3, the second conveyor belt 6 is arranged perpendicular to the first conveyor belt 3, a horizontal pushing device is arranged on the other side of the first conveyor belt 3, and the horizontal pushing device is used to push the medicine bottles 8 on the first conveyor belt 3 onto the second conveyor belt 6.

[0021] The medicine bottle feeding assembly 1 can have a slight slope, and the medicine bottles 8 gathered in the medicine bottle feeding assembly 1 move toward the feeding screw 2. A screw drive motor 201 is provided at one end of the feeding screw 2 to drive the feeding screw 2 to rotate, and the medicine bottles 8 are stuck in the thread interval of the feeding screw 2, and a first conveyor belt 3 is provided at the bottom. The moving speed of the first conveyor belt 3 is consistent with the driving speed of the feeding screw 2, so that the medicine bottles 8 embedded in the pitch are conveyed forward one by one. When they reach the shooting device 4, the light board 5 provides background lighting, and the shooting device 4 shoots the liquid level boundary line. The background system confirms whether the liquid level meets the standard. If it does not meet the standard, the horizontal pushing device pushes the medicine bottle 8 to the second conveyor belt 6 on the side and transports it off the line.

[0022] In a preferred solution, first side baffles 301 are provided on both sides of the first conveyor belt 3 , and a notch 302 is provided at the end of the second conveyor belt 6 on the first side baffle 301 close to the second conveyor belt 6 .

[0023] Second side baffles 601 are also provided on both sides of the second conveyor belt 6 to prevent elongated bottles such as oral liquid bottles from tipping over during transportation.

[0024] In a preferred solution, the horizontal pushing device is a horizontal pushing cylinder 7, and a pushing frame 701 is provided at the cylinder rod end of the horizontal pushing cylinder 7, and the pushing frame 701 pushes the medicine bottle 8 horizontally.

[0025] In a preferred embodiment, a unidirectionally rotatable rotating frame 9 is provided above the first conveyor belt 3 . The rotating frame 9 is provided with a plurality of evenly distributed outrigger arms 901 along the circumference of the rotating shaft. A hinged push block 902 is provided at the end of the outrigger arm 901 .

[0026] If the conveying speed of the medicine bottles 8 is slow, the horizontal push cylinder 7 can be used for horizontal push screening, but the push rack 701 needs to be reset in time after horizontal push to wait for the next material push.

[0027] If the conveying speed of the medicine bottles 8 is fast and the spacing between the medicine bottles 8 is small, it is not enough to allow the push rack 701 to have enough time to return. In this case, a turntable type push structure can be used, and a reduction motor is installed at the shaft end of the rotating rack 9 to drive each outrigger 901 to rotate in one direction. The horizontal push block 902 does not need to be reset. When there are no defective products, the horizontal push block 902 can be used as a baffle to fill the gap 302 to prevent the medicine bottles 8 from leaking out of the gap 302.

[0028] In a preferred solution, an arc-shaped recessed portion 904 is provided on one side of the horizontal push block 902 , and a counterweight block 903 is provided at the lower end of the horizontal push block 902 .

[0029] The push block 902 and the counterweight block 903 are installed with screws so that the center of the entire block is located below the hinge axis. The push block 902 is always in a vertical state, which is convenient for pushing the medicine bottle 8 horizontally. An arc-shaped recessed portion 904 is provided on the side of the push block 902 facing the medicine bottle 8 to prevent the medicine bottle 8 from moving sideways during pushing.

[0030] In the preferred embodiment, the medicine bottle feeding assembly 1 includes a base plate 109, on which are provided parallel limit baffles 101, an extrusion plate 102 is provided between the two limit baffles 101, a second guide sleeve 108 is further provided on the base plate 109, a second guide rod 107 is provided in the second guide sleeve 108, a support plate 103 is provided at one end of the second guide rod 107, a first guide sleeve 105 is provided on the support plate 103, a first guide rod 104 is provided on the side of the extrusion plate 102 away from the feeding screw 2, the first guide rod 104 is slidably connected with the first guide sleeve 105, a first spring 106 is provided between the support plate 103 and the extrusion plate 102, and a linear electric cylinder 110 is further provided on the base plate 109, which drives the support plate 103.

[0031] In the preferred embodiment, the medicine bottle feeding assembly 1 is provided with a neck portion 117 near the feeding screw 2, the extrusion plate 102 is provided with a snap-in groove 115, and top blocks 111 are provided at both ends of the extrusion plate 102. A second spring 116 is provided in the snap-in groove 115, and both ends of the second spring 116 are respectively abutted against each top block 111. An arc groove 114 is provided at the protruding end of the top block 111, and a rotatable roller 112 is provided in the arc groove 114. The roller 112 rolls against the inner wall of the limit baffle 101.

[0032] Due to the holding force of the first spring 106, the extrusion plate 102 can continuously squeeze the medicine bottle 8, so that even without using an inclined surface, the medicine bottle 8 can continuously move closer to the feeding screw 2, and the spring structure allows a certain buffer margin during extrusion to prevent the medicine bottle 8 from being crushed.

[0033] Since the medicine bottle feeding assembly 1 is provided with an oblique guide block near the feeding screw 2 to form a necking structure, when the extrusion plate 102 is pushed horizontally to this point, the originally extended top block 111 gradually retracts to adapt to the change in the total width.

[0034] A baffle 113 is provided at the upper end of the rotating roller 112 , and the baffle 113 is placed on the upper edge of the limiting baffle 101 and the top block 111 to prevent the rotating roller 112 from falling out.

[0035] The above embodiments are only preferred technical solutions of the present invention and should not be regarded as limitations of the present invention. The protection scope of the present invention shall be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
