Abstract
Description
Technical Field
[0001] The utility model relates to a taurine filling device. Background Art
[0002] With consumers' increasing attention to health and nutrition, taurine, an amino acid with multiple physiological functions, is finding widespread application in food, medicine, and other fields. For convenient consumption, taurine is currently formulated into liquid forms (such as oral liquids) and bottled for storage. This production process often requires filling equipment. Existing filling equipment typically uses a conveyor belt to transport liquid bottles to a filling head, where the taurine liquid is poured into the bottles. The filled bottles are then transported to the next station (such as a capping station or a capping station) via a turntable and conveyor belt. However, existing filling equipment lacks position limits perpendicular to the conveying direction of the bottles during filling. This can easily lead to overflow of the taurine liquid due to inaccurate position limits. Furthermore, when transferring filled bottles, a push plate is typically used to push the bottles from the turntable to the conveyor belt. However, improperly positioned push points on the push plate can easily cause the bottles to fall over. To this end, it is necessary to improve the above technical problems, and this case came into being. Utility Model Content

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.
[0022] In the description of the present invention, it should be understood that the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on the present invention.
[0023] like Figure 1 As shown, the utility model provides a taurine filling device, which includes a filling structure and a bottle discharge mechanism arranged from right to left. The filling structure is used to fill taurine liquid into the liquid bottles placed vertically, and after filling, the bottle discharge mechanism outputs the taurine liquid so as to be sent to the next workstation (such as the capping station, the capping station, etc.).
[0024] like Figures 1 to 5 As shown, the filling structure includes a frame 1 and a conveyor belt 2 installed on the frame 1 for conveying taurine liquid bottles, a first guide rail 3 and a second guide rail 4 arranged above the conveyor belt 2 and connected in sequence, and the conveyor belt 2 is a belt conveyor.
[0025] The second guide track 4 branches into two parallel adjacent first channels 5 and second channels 6 that can only pass one liquid bottle K in sequence. That is, the width of the first channel 5 and the second channel 6 is only equivalent to the diameter of the liquid bottle K.
[0026] The inlet ends of the first channel 5 and the second channel 6 are both connected to the outlet end of the first guide track 3. A perfusion head 7 for perfusing taurine liquid into the liquid bottle is provided above the second guide track 4. The perfusion head 7 is connected to the perfusion pump 8 through a pipeline for pumping taurine liquid. After the perfusion pump 8 is working, the taurine liquid can be pumped into the liquid bottle K.
[0027] The second guide rail 4 is composed of a first side baffle 9, a second side baffle 10 and an intermediate baffle 11 located between the first side baffle and the second side baffle. A first channel 5 and a second channel 6 are formed between the two baffles. Two groups of spaced and parallel retractable baffles 12 are provided between the first side baffle, the second side baffle and the conveyor belt (the baffles 12 are driven to retract by a telescopic cylinder or an electric push cylinder). The retraction direction of the baffles is perpendicular to the length direction of the first side baffle and the second side baffle. The interval position of the two groups of baffles is opposite to the position of the filling head. Under the synchronous retraction action of the two groups of baffles, the limiting position of several liquid bottles is realized. The limiting position is opposite to the bottom of the filling head, so that the filling head is accurately positioned during filling, avoiding overflow caused by inaccurate filling position.
[0028] The first side baffle 9, the second side baffle 10 and the middle baffle 11 are fixedly connected by an inverted E-shaped connecting plate 13 located above them. There are several inverted E-shaped connecting plates 13 in the length direction of the first side baffle 9, the second side baffle 10 and the middle baffle 11. The first side baffle 9 and the second side baffle 10 are fixed to the frame 1 by bolts.
[0029] For a reasonable design, four liquid bottles can be accommodated between the two groups of baffles 12, and the filling head has four groups facing the four liquid bottles.
[0030] The above-mentioned perfusion pump 8 includes a cylindrical tubular pump housing 25 vertically fixed on the frame 1 and a lifting piston 14 extending from bottom to top into the pump housing. A sealing cover 15 is provided on the upper opening of the pump housing, and the sealing cover is sealed and connected to the inlet and outlet pipes 16. The inlet and outlet pipes 16 are connected to the first port of the three-way pipe 17, and the second port of the three-way pipe is connected to the first one-way valve 18 and then connected to the perfusion head 7 through a pipeline. The third port of the three-way pipe is connected to the second one-way valve 19 and then communicated with the taurine storage tank 20 through a pipeline. Multiple groups of pump housings 25 are installed on the frame, and each lifting piston 14 extending into the multiple groups of pump housings is fixedly connected to the lifting plate 26, and the lifting plate is connected At the output end of the lifting cylinder 27 (or electric push cylinder), when the lifting cylinder 27 contracts, the lifting plate 26 and the lifting piston 14 are pulled down, thereby drawing the taurine liquid in the taurine storage tank 20 into the pump housing 25 through the second one-way valve 19 (at this time, the second one-way valve 19 is conductive and the first one-way valve 18 is not conductive). Then, when the lifting cylinder 27 extends, the lifting plate 26 and the lifting piston 14 are pulled up, thereby pushing the taurine liquid in the pump housing 25 through the first one-way valve 18 and the filling head 7 into the liquid filling bottle K (at this time, the second one-way valve 19 is not conductive and the first one-way valve 18 is conductive). The above steps are repeated to fill the liquid filling bottle K.
[0031] The above-mentioned first guide rail 3 includes a first side bar 23 and a second side bar 24 arranged in parallel and at intervals. The distance between the first side bar and the second side bar is smaller than the distance between the first side block bar and the second side block bar. A notch portion 21 is provided on the first side bar 23, and the first side bar 23 is flush with the first side block bar 9. The position of the second side bar 24 facing the notch portion is a bending portion 28, so that the end of the second side bar is connected with the end of the second side block bar.
[0032] In order to realize the diversion of bottles into the first channel 5 and the second channel 6, a notch 21 is provided on the first side portion of the outlet end of the above-mentioned first guide rail 3, and a push plate 22 is installed on the notch portion, which can swing toward the second side portion of the outlet end of the first guide rail (one end of the push plate 22 is rotatably hinged on the frame, and the other end is connected to the free end of an electric push rod 29), so that the outlet end of the first guide rail is only connected to the second channel and not to the first channel. When the taurine packaging bottle K travels on the conveyor belt 2 and enters the second guide rail 4 from the first guide rail 3, when the push plate 22 is not moving, since the first side bar 23 is flush with the first side stop bar 9, the liquid bottle K enters the second channel 6 directly from the first guide rail 3, and when the push plate 22 is pushed forward and swung, the liquid bottle K is guided from the first guide rail 3 into the first channel 5; through the action of the push plate 22, the taurine packaging bottle K is diverted into the first channel 5 or the second channel 6.
[0033] When the filling structure is working, the liquid bottle travels on the conveyor belt, passes through the first guide track and then enters the second guide track. The first channel and the second channel in the second guide track can only pass one liquid bottle in sequence. Under the synchronous extension and contraction of the two sets of baffles, a plurality of liquid bottles are limited. The limit position is just below the filling head, so that the filling head is accurately positioned during filling, avoiding overflow caused by inaccurate filling position.
[0034] like Figure 1 、 6 As shown, the bottle discharging mechanism includes a horizontal working platform 01, on which an axially vertical bottle feeding turntable 02 is provided. A conveyor belt assembly 03 and a bottle pushing assembly 04 are provided on the discharge side of the bottle feeding turntable. The bottle pushing assembly consists of an upper push rod 05 located above the bottle feeding turntable and a lower push rod 06 located below the bottle feeding turntable. The upper and lower push rods are driven by a driving assembly to reciprocate between the discharge side of the bottle feeding turntable and the feed side of the conveyor belt assembly.
[0035] The bottle feed turntable is uniformly distributed around its outer circumference, with several notches 08 for accommodating liquid bottles k. The turntable is mounted on a work platform via a rotating shaft at its center and is driven by a motor for intermittent rotation. During operation, the first and second channels 5 and 6 of the filling mechanism each deliver a liquid bottle to the left. The bottles in the first and second channels enter adjacent notches on the bottle feed turntable, where they are then transported counterclockwise.
[0036] There is a gap between the bottom surface of the bottle feeding turntable and the working platform, and the lower push rod is located in the gap.
[0037] The driving assembly is a double-piston-rod cylinder 09, the cylinder body of which is fixedly connected to the working platform, one piston rod of which is fixedly connected to the upper push rod, and the other piston rod of which is fixedly connected to the lower push rod.
[0038] The sides of the upper and lower push rods for contacting the liquid bottle are fixedly connected with rubber strips 010 to avoid scratching the liquid bottle.
[0039] The conveying direction of the conveyor belt assembly is tangential to the discharge side of the bottle feeding turntable and perpendicular to the translation direction of the upper and lower push rods. The feed side of the conveyor belt assembly corresponds to the discharge side of the bottle feeding turntable in the translation direction of the upper and lower push rods.
[0040] The upper surface of the conveyor belt assembly is flush with the upper surface of the working platform, or the upper surface of the conveyor belt assembly is slightly lower than the upper surface of the working platform.
[0041] The conveyor belt assembly is provided with a side baffle 011 on the side away from the bottle feeding turntable, and a rubber sheet 012 is fixedly connected to the inner side of the side baffle. A mounting shaft 013 is fixedly provided on the outer side of the side baffle. The axial direction of the mounting shaft is the width direction of the conveyor belt assembly. The outer periphery of the mounting shaft is coaxially provided with a shaft sleeve 014. The shaft sleeve is fixed on the external frame, and a set screw 015 is screwed on the shaft sleeve.
[0042] The rubber sheet on the inside of the side baffle is used to prevent the liquid bottle from being scratched. The position of the side baffle can be adjusted along the width direction of the conveyor belt assembly by loosening and tightening the set screws.
[0043] Two transverse baffles 07 are provided above the conveyor belt assembly. The two transverse baffles 07 are spaced apart in the longitudinal direction and form a third channel for a liquid bottle to pass through.
[0044] The bottle discharge mechanism works as follows: As the bottle feed turntable intermittently rotates forward, it stops rotating and the conveyor assembly stops when a bottle reaches the discharge side. The upper push rod's push point is above the bottle, while the lower push rod's push point is below the bottle. Driven by a pneumatic cylinder, the upper and lower push rods simultaneously push the bottle, pushing it directly into the feed side of the conveyor assembly. The conveyor assembly transports the bottle from right to left to the next station. The upper and lower push rods then reset, the conveyor assembly operates, and the bottle feed turntable begins operating, and the process repeats.
[0045] The advantages of this bottle discharging mechanism are:
[0046] 1. In order to prevent the liquid bottle from being pushed over, an upper and lower push rod are set. The push point of the upper push rod is at the upper part of the liquid bottle, and the push point of the lower push rod is at the lower part of the liquid bottle. The upper and lower push rods push the bottle at the same time. In this way, the liquid bottle is not easy to fall over because the upper and lower push points have support.
[0047] 2. In order to achieve efficient transfer, a conveyor belt assembly is set on the discharge side of the bottle feeding turntable. The liquid bottles are directly pushed into the feed side of the conveyor belt assembly by the upper and lower push rods, and then transported to the next workstation by the conveyor belt assembly, which improves the transfer efficiency and reduces the workload of workers.
[0048] If the present invention discloses or involves components or structural parts that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the mutual fixed connection can also be replaced by an integrated structure (for example, manufactured by integral molding using a casting process) (except where it is obviously impossible to use an integrated molding process).
[0049] In addition, unless otherwise stated, the terms used in any technical solution disclosed in the above-mentioned utility model to express positional relationships or shapes include states or shapes that are approximate, similar or close thereto.
[0050] Any component provided by the present invention may be assembled from a plurality of separate components, or may be a separate component manufactured by an integral forming process.
[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and not to limit it; although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents; without departing from the spirit of the technical solution of the utility model, they should all be included in the scope of the technical solution for protection of the utility model.
