Description

Technical Field

[0001] This invention relates to the field of beverage bottle conveying technology, specifically a bottle conveyor for a collagen beverage filling production line. Background Technology

[0002] Collagen drinks are liquid dietary supplements with small-molecule collagen peptides as the core ingredient. They are usually also formulated with ingredients such as vitamin C, hyaluronic acid, argan strawberry, and PQQ. They are designed to help improve skin elasticity, promote joint health, and strengthen hair and nails through oral administration. Collagen drinks are usually bottled and processed like regular beverages for subsequent sales. Currently, collagen drink bottles are transported in batches by conveyor lines to improve filling efficiency.

[0003] Application CN215945765U discloses a glue bottle conveyor. The conveying structure includes a motor, a connecting shaft, a chain plate, a chain, and a sprocket. The motor is mounted on a support frame, the connecting shaft is mounted on the motor drive end, the sprocket is mounted on the connecting shaft, the chain is mounted on the sprocket, and the chain plate is mounted on the chain. A buffer positioning structure is provided to ensure that the bottle does not move during transportation and can be transported stably to the glue bottling machine. Moreover, during the bottling process, it can provide a certain buffering effect on the bottle to prevent tipping.

[0004] Application CN205500146U discloses a bottle conveyor. After the bottle is adjusted by an intelligent module, it can be placed into the transmission module with the bottle mouth facing upward. The transmission module can only accommodate one bottle at a time, so that the bottles will not be squeezed during the conveying process and the bottles will not tip over. Thus, the bottle is always positioned with the bottle mouth facing upward until it is output through the output module.

[0005] However, the aforementioned bottle conveying mechanism still has the following problems in actual use. The bottle is conveyed by the conveying base above the conveyor belt, but there is no corresponding clamping and positioning component between the conveyor mechanism and the conveyor base. The bottle cannot be uniformly adapted when placed inside the conveyor base. The inertia generated when the conveyor belt rotates and moves can easily cause the bottle to tip over. At the same time, the bottle opening facing upwards can easily allow fine dust to enter during the transfer process, affecting subsequent filling operations.

[0006] Therefore, we propose a bottle conveyor for collagen beverage filling production lines to solve the problems mentioned above. Summary of the Invention

[0007] The purpose of this invention is to provide a bottle conveyor for a collagen beverage filling production line. This invention addresses the problems of existing conveyor systems that transport bottles via a conveyor base above a conveyor belt. However, such conveyor mechanisms lack corresponding clamping and positioning components with the conveyor base, making it difficult to uniformly fit the bottles inside the conveyor base. Furthermore, the inertia generated during the rotation of the conveyor belt can easily cause the bottles to tip over, and the upward-facing bottle openings can allow fine dust to enter during transport, affecting subsequent filling operations.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a bottle conveyor for a collagen beverage filling production line, comprising a conveyor frame and conveyor rollers rotatably mounted on the left and right sides of the upper end of the conveyor frame via bearings, wherein the outer wall of the conveyor rollers is meshed with a conveyor belt for conveying the filling bottles on the upper surface. A positioning mechanism is provided inside the upper part of the conveyor frame, and the positioning mechanism includes a positioning side plate. A positioning bracket is fixedly installed on the inner side of the upper end of the positioning side plate for fitting the filling bottle body to achieve positioning. The positioning mechanism includes a positioning base, and positioning claws are slidably installed on both the front and rear sides of the positioning base. The upper end of the conveyor frame is equipped with an adsorption mechanism, which includes an adsorption cone tube. The adsorption cone tube slides into the filling bottle to suck up and clean the residue.

[0009] Preferably, the positioning mechanism includes a positioning side plate fixedly installed on the front and rear sides of the middle of the conveyor frame, and the positioning bracket on the inner side of the upper end of the positioning side plate extends to the middle of the conveyor belt in an inclined inward manner. A positioning roller is rotatably installed at the inner center of the positioning bracket through a bearing at equal distances. The positioning roller is in contact with the outer wall of the filling bottle to achieve positioning during conveying.

[0010] Preferably, the positioning mechanism includes a positioning base that is movably mounted on the outer wall of the conveyor belt via a hinged seat on the bottom surface. The positioning base is installed and distributed at equal angles on the outer wall of the conveyor belt. A bearing groove is provided inside the positioning base on the side away from the conveyor belt, and the bottom end of the filling bottle is inserted into the bearing groove.

[0011] Preferably, the inner end of the positioning claw included in the positioning mechanism slides through the interior of the positioning base, and the inner end of the positioning claw is located inside the bearing slot, and the outer end of the positioning claw slides through the front and rear sides of the outer side of the positioning base, and the outer wall of the positioning base and the positioning claw are connected to each other by a return spring.

[0012] Preferably, the positioning mechanism includes a contact plate, the outer end of which is inclined outward, and the contact plate is fixedly installed on the inner upper side of the positioning brackets on the front and rear sides, and the bottom horizontal height of the contact plate is higher than the top horizontal height of the conveyor belt.

[0013] Preferably, the inner side of the contact plate included in the positioning mechanism is located above the conveyor belt, and the outer ends of the contact plate and the positioning claws distributed front and back above the conveyor belt correspond to each other. After the positioning claws and the contact plate come into contact with each other, the positioning claws are squeezed to move closer to the center position of the bearing slot inside the positioning base, and the positioning claws fit against the outer wall of the filling bottle.

[0014] Preferably, the adsorption mechanism includes an adsorption bracket, and the bottom end of the adsorption bracket is fixedly installed on the left and right sides of the positioning bracket in a symmetrical manner. The upper end of the adsorption bracket, which is symmetrically distributed in the front and back, is rotatably mounted with an adsorption roller through a bearing. The outer walls of the adsorption rollers on the left and right sides are meshed with adsorption tracks, and the adsorption tracks and the conveyor tracks are distributed in a transversely parallel manner.

[0015] Preferably, the adsorption mechanism includes a storage box, which is fixedly installed at equal intervals inside the adsorption track. A suction pump is fixedly installed at the end of the storage box away from the adsorption track, and the storage box and the suction pump move together through the groove in the middle of the adsorption roller.

[0016] Preferably, the adsorption mechanism includes a hydraulic cylinder, which is installed at equal intervals on the outer surface of the adsorption track. The inner end of the hydraulic cylinder is distributed in relation to the storage box on the inner wall of the adsorption track. The lower end of the hydraulic cylinder is fixedly connected to the inner end of the adsorption cone tube. The hydraulic cylinder drives the adsorption cone tube to move up and down and slide, so as to achieve the suction and cleaning of residues after entering the filling bottle.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: The bottle conveyor for a collagen beverage filling production line corresponds to the filling bottle through the positioning base and positioning bracket above the conveyor frame. During the conveying operation, the filling bottle is autonomously positioned, and the movable adsorption cone enters the filling bottle to perform adsorption, thereby improving the convenience and efficiency of the overall conveying operation. The specific details are as follows: 1. The drive motor at the rear of the conveyor frame drives the conveyor roller to rotate and engages with the conveyor belt and the positioning base on its outer surface to rotate and move. After the positioning base moves to the upper surface of the conveyor belt, the bottle is placed in the bearing slot inside the positioning base. The bearing slot supports the bottle and drives the bottle to move.

[0018] Furthermore, the positioning claws on the front and rear sides of the positioning base contact each other with the abutting horizontal plate on the inner side of the positioning side plate. The abutting horizontal plate presses the positioning claws to move them into the interior of the bearing slot, so that the inner end of the positioning claws fits against the bottom outer wall of the filling bottle, thereby limiting the filling bottle and preventing it from tipping over during the conveying process.

[0019] 2. The conveyor belt drives the positioning base and the filling bottle to move continuously. When it approaches the middle of the positioning side plate, it is brought into contact with the positioning bracket and the internal positioning roller, so that the positioning roller and the filling bottle can make contact and limit the movement, which helps to improve the stability of the filling bottle during subsequent adsorption and dust removal operations.

[0020] 3. The adsorption roller drives the adsorption track, which is meshed with the outer wall, to rotate and move. At the same time, the adsorption track drives the hydraulic cylinders and adsorption cone tubes, which are fixed at equal intervals, to move, so as to match the filling bottles that are moved and conveyed below.

[0021] Furthermore, the hydraulic cylinder drives the adsorption cone to slide downwards, allowing it to enter the interior of the corresponding filling bottle. Then, a suction pump draws in the adsorption cone to remove dust particles from the bottle and transport them to the storage box for storage. The bottle is then automatically unloaded when it moves to the right, improving the convenience and efficiency of the overall conveying operation. Attached Figure Description

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figures 1-11 The present invention provides the following technical solution: Example 1: To solve the problems existing in the conveying process of beverage bottles, this example discloses the following technical solution: a bottle conveyor for a collagen beverage filling production line, including a conveyor frame 1 and conveyor rollers 2 rotatably mounted on the left and right sides of the upper end of the conveyor frame 1 via bearings, and a conveyor belt 3 is meshed with the outer wall of the conveyor rollers 2 for conveying the filled bottles 4 on the upper surface; a positioning mechanism is provided inside the upper part of the conveyor frame 1, and the positioning mechanism includes a positioning side plate 5; wherein, the positioning mechanism includes a positioning base 7, and positioning claws 9 are slidably installed on both the front and rear sides of the positioning base 7; the positioning base 7 included in the positioning mechanism is movably set on the outer wall of the conveyor belt 3 through a hinge seat on the bottom surface, and the positioning base 7 is installed and distributed at equal angles on the outer wall of the conveyor belt 3, and a bearing slot 8 is opened inside the side of the positioning base 7 away from the conveyor belt 3, and the bottom end of the filled bottle 4 is inserted into the bearing slot 8.

[0026] The positioning mechanism includes a positioning claw 9 whose inner end slides through the interior of the positioning base 7, and the inner end of the positioning claw 9 is located inside the bearing slot 8. The outer end of the positioning claw 9 slides through the front and rear sides of the positioning base 7. The outer wall of the positioning base 7 and the positioning claw 9 are connected to each other by a return spring 10. The positioning mechanism includes a contact plate 11, and the outer end of the contact plate 11 is inclined outward. The contact plate 11 is fixedly installed on the inner upper side of the positioning brackets 6 on the front and rear sides. The bottom horizontal height of the contact plate 11 is higher than the top horizontal height of the conveyor belt 3.

[0027] The inner side of the contact plate 11 included in the positioning mechanism is located above the conveyor belt 3, and the outer ends of the contact plate 11 and the positioning claws 9 distributed front and back above the conveyor belt 3 correspond to each other. After the positioning claws 9 and the contact plate 11 come into contact with each other, the positioning claws 9 are squeezed to approach the center position of the bearing slot 8 inside the positioning base 7, and the positioning claws 9 fit against the outer wall of the filling bottle 4.

[0028] like Figures 5-8 As shown, the conveyor frame 1 drives the left and right conveyor rollers 2 to rotate via the motor at the rear. The conveyor rollers 2 drive the conveyor belt 3, which is meshed with the outer wall, to rotate. This allows the conveyor belt 3 to continuously move the positioning base 7, which is movably connected to the outer surface. When the positioning base 7 moves to the upper surface of the conveyor belt 3, the filling bottle 4 is placed in the bearing slot 8 opened inside the positioning base 7, so that the conveyor belt 3 can drive the positioning base 7 and the filling bottle 4 to move and transport.

[0029] Furthermore, as the positioning base 7 moves the filling bottle 4 placed inside, the positioning claws 9 installed on the front and rear sides of the positioning base 7 follow synchronously, so as to contact the abutting horizontal plates 11 on the inner side of the positioning side plates 5 at the front and rear ends of the conveyor frame 1. The positioning claws 9, which move by being pressed by the abutting horizontal plates 11, press the return spring 10 on the inner side and drive the inner end to move towards the center of the bearing slot 8 inside the positioning base 7, so that the inner end of the positioning claws 9 fits against the bottom outer wall of the filling bottle 4, thereby limiting the filling bottle 4 and preventing it from tipping over during the conveying process.

[0030] Example 2: In order to solve the problems existing in the transportation of beverage bottles, this example discloses the following technical solution: a positioning bracket 6 is fixedly installed on the inner side of the upper end of the positioning side plate 5 for fitting the filling bottle 4 to achieve positioning; the positioning mechanism includes a positioning side plate 5 fixedly installed on the front and rear sides of the middle of the conveyor frame 1, and the positioning bracket 6 on the inner side of the upper end of the positioning side plate 5 extends to the middle of the conveyor belt 3 in an inclined inward manner, and a positioning roller 19 is rotatably installed at the center of the internal position of the positioning bracket 6 through bearings at equal distances, and the positioning roller 19 fits against the outer wall of the filling bottle 4 to achieve positioning during transportation.

[0031] like Figures 2-4 As shown, the filling bottle 4 above the conveyor frame 1 is abutted by the positioning claw 9 inside the positioning base 7, and the positioning base 7 and the filling bottle 4 are continuously moved by the conveyor belt 3. When the filling bottle 4 moves close to the middle of the positioning side plate 5, the positioning bracket 6 at the upper end of the positioning side plate 5 and the positioning roller 19 inside it are in contact, so that the positioning roller 19 and the filling bottle 4 make contact and limit each other, thereby helping to improve the stability of the filling bottle 4 in the subsequent adsorption and dust removal operation.

[0032] Example 3: In order to solve the problems existing in the transportation process of beverage bottles, this example discloses the following technical solution: The upper end of the conveyor frame 1 is provided with an adsorption mechanism, and the adsorption mechanism includes an adsorption cone tube 18. The adsorption cone tube 18 slides into the filling bottle 4 to suck up and clean the residue. The adsorption mechanism includes an adsorption bracket 12. The bottom end of the adsorption bracket 12 is fixedly installed on the left and right sides of the positioning bracket 6 in a symmetrical manner. The upper end of the adsorption bracket 12, which is symmetrically distributed in the front and back, is rotatably mounted with an adsorption roller 13 through a bearing. The outer walls of the adsorption rollers 13 on the left and right sides are meshed with an adsorption track 14. The adsorption track 14 and the conveyor track 3 are distributed in a transverse parallel manner.

[0033] The adsorption mechanism includes a storage box 15, which is fixedly installed at equal intervals inside the adsorption conveyor belt 14. A suction pump 16 is fixedly installed at the end of the storage box 15 away from the adsorption conveyor belt 14. The storage box 15 and the suction pump 16 move together through the groove in the middle of the adsorption roller 13. The adsorption mechanism includes a hydraulic cylinder 17, which is installed at equal intervals on the outer surface of the adsorption conveyor belt 14. The inner ends of the hydraulic cylinder 17 are distributed on the storage box 15 on the inner wall of the adsorption conveyor belt 14. The lower end of the hydraulic cylinder 17 is fixedly connected to the inner end of the adsorption cone tube 18. The hydraulic cylinder 17 drives the adsorption cone tube 18 to move up and down and slide, so as to achieve the suction and cleaning of residues after entering the filling bottle 4.

[0034] like Figures 9-11As shown, the filling bottle 4 above the conveyor frame 1 is positioned by the positioning base 7 and the positioning bracket 6 during the movement, thereby ensuring the stability during the movement. At the same time, the adsorption bracket 12 above the positioning side plate 5 supports the adsorption cone tube 18. The motor above the adsorption bracket 12 drives the adsorption roller 13 to rotate, and the adsorption roller 13 drives the adsorption track 14 connected to the outer wall to rotate and move. At the same time, the adsorption track 14 drives the hydraulic cylinder 17 and the adsorption cone tube 18, which are fixed at equal distances, to move, thereby matching with the filling bottle 4 moving and conveyed below.

[0035] Furthermore, after the adsorption conveyor belt 14 moves the hydraulic cylinder 17 and the adsorption cone tube 18 on the outer wall to the lower surface, the hydraulic cylinder 17 drives the adsorption cone tube 18, which is fixedly connected to the outer end, to slide downward so that the adsorption cone tube 18 enters the interior of the corresponding filling bottle 4. Then, the suction pump 16 on the inner side of the adsorption conveyor belt 14 sucks into the interior of the adsorption cone tube 18 so that the adsorption cone tube 18 sucks in the dust particles inside the corresponding filling bottle 4 and transports them to the storage box 15 for storage.

[0036] Furthermore, when the adsorption cone 18 moves with the filling bottle 4 to the right side of the conveyor frame 1, the hydraulic cylinder 17 drives the adsorption cone 18 to move upward so that the adsorption cone 18 and the filling bottle 4 are separated from each other. At the same time, the positioning claws 9 on the front and rear sides of the positioning base 7 at the bottom of the filling bottle 4 are separated from the contact plate 11. Thus, the extension of the return spring 10 drives the positioning claws 9 to move outward synchronously, so that they no longer clamp and position the filling bottle 4. This allows the filling bottle 4 to be unloaded autonomously when it moves to the right end of the conveyor belt 3, improving the convenience of the overall conveying operation.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
