Abstract
Description
Technical Field
[0001] This utility model relates to the field of liquid filling technology, specifically a glass bottle positioning and filling device. Background Technology
[0002] In modern bottling production lines, glass bottle positioning and filling devices are key components ensuring smooth filling operations. Their core function is to precisely fix the glass bottles, ensuring their stable position during filling and providing the necessary conditions for subsequent filling operations. As market demands for both product quality and production efficiency continue to rise, the performance of positioning devices becomes increasingly crucial.
[0003] Traditional glass bottle positioning and filling devices have some limitations. During the transport process, glass bottles may shift in position due to factors such as vibration and speed changes, and existing positioning devices cannot correct this in a timely and accurate manner. Due to the different bottle shapes, the positioning devices cannot effectively and accurately limit the position of all glass bottles. Furthermore, the surface of glass bottles is relatively smooth and is prone to shifting under pressure, resulting in bottles not being in the ideal position during filling.
[0004] There is a close and direct link between inaccurate positioning and inaccurate filling. When the glass bottle is misaligned, the filling head and the bottle neck cannot be precisely aligned, which can easily lead to problems such as uneven filling volume and spillage of the filling liquid.

[0027] The third U-shaped bracket is fixed to one end of the electric push rod and is slidably inserted into the third sliding hole.
[0028] Preferably, the left and right fine-tuning mechanism includes:
[0029] The second inclined frame slides inside the first sliding hole. One end of the second inclined frame is fixedly connected to the second elastic push rod, and one end of the second elastic push rod is fixedly connected to the rubber pad.
[0030] Preferably, the leak-proof mechanism includes:
[0031] Two sets of L-shaped frames are provided and fixed to the top wall of the conveying unit.
[0032] The third inclined frame slides between the inner walls of a set of L-shaped frames, and a spring is fixedly connected to one end of the third inclined frame.
[0033] The cube is fixed between the inner walls of a set of L-shaped frames and is also fixed to one end of the spring;

[0038] Compared with the prior art, the beneficial effects of this utility model are:
[0039] 1. By using two sliding rails in the front and rear fine-tuning mechanism to move through both sides of the bottle, with one end contacting the inclined frame and converging towards the center, the position of the bottle can be effectively adjusted forward and backward. This solution can accurately correct the positional deviation of the glass bottle caused by factors such as vibration and speed changes during the conveying process. The front and rear fine-tuning mechanism can move the bottle to a position close to the valve of the filling mechanism. Combined with the left and right fine-tuning mechanism, the bottle is stably aligned with the filling center, which greatly improves the positioning accuracy.
[0040] 2. The electric push rod pushes the U-shaped frame three, which compresses the two inclined frames two on both sides, causing the rubber pads to converge towards the center, thus completing the left and right adjustment. Combined with the front and rear micro-adjustment mechanism, it can solve the problem that traditional positioning devices cannot correct position deviations in a timely and accurate manner, so that the filling head and the bottle mouth can be precisely aligned. This effectively avoids problems such as uneven filling volume and liquid spillage, significantly improving the quality of filled products, reducing material waste, and lowering the defect rate.
[0041] 3. The U-shaped frame moves upward under the influence of the electric push rod and contacts the inclined frame three. The inclined frames on both sides squeeze and drive the hopper downward to accurately insert it into the bottle mouth. This design effectively prevents leakage caused by misalignment of the bottle mouth during filling. It also avoids liquid splashing outside the bottle due to abnormal hydraulic pressure when opening or closing the valve. This not only reduces material waste but also keeps the filling production line clean and hygienic, improves the production environment, reduces the risk of corrosion damage to the equipment caused by liquid leakage, and extends the service life of the equipment.

Detailed Implementation
[0049] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0050] Please see Figure 1-6In this embodiment of the present invention, a glass bottle positioning and filling device includes a bottle positioning mechanism 100. The bottle positioning mechanism 100 includes a conveying unit 110 and the following components: sliding holes 111 are provided on both outer walls of the conveying unit 110; a second sliding hole 112 is provided on the outer wall of the conveying unit 110 near the lower part of the first sliding hole 111; and a third sliding hole 113 is provided on the outer wall of the conveying unit 110 on one side of the first sliding hole 111. A filling mechanism 200 is fixed to one side of the conveying unit 110. Furthermore, the front-to-back fine-tuning mechanism 300 is fixed to the outer wall of the conveying unit 110 near the filling mechanism 200, enabling the bottles to be adjusted forward and backward. The left-to-right fine-tuning mechanism 400 is fixed inside the conveying unit 110, enabling the bottles to be adjusted left and right. Its anti-leakage mechanism 500 is fixed to the top wall of the conveying unit 110, preventing filling leakage. The front-to-back fine-tuning mechanism 300 includes the following parts: its fixing frame 310 is fixed to the outer wall of the conveying unit 110, and the motor 311 is fixed to the outer wall of the fixing frame 310. A threaded rod 312 is fixedly connected to the rotating shaft of motor 311. A square plate 313 is screwed onto the outer wall of the threaded rod 312. Two slide rails 314 are provided, both sliding on the outer wall of the square plate 313. A second U-shaped frame 340 is fixed to the outer wall of the conveying unit 110. The outer wall of the second U-shaped frame 340 is rotatably connected to one end of the threaded rod 312. Two square frames 320 are provided, respectively fixed to the inside of the conveying unit 110 on both sides of the filling mechanism 200. An elastic push rod 32 is fixedly connected to one side of the square frame 320. 1. The U-shaped frame 322 is fixed at one end of the elastic push rod 321 and is slidably inserted into the sliding hole 112. There are two sliders 323, which are fixed at both ends of the U-shaped frame 322 respectively. The outer wall of the slider 323 is slidably inserted into the inside of the slide rail 314. A set of inclined frames 330 is provided and fixed to the outer wall of the conveying unit 110. The two slide rails 314 in the front and rear fine adjustment mechanism 300 move through the two sides of the bottle, one end of which contacts the inclined frame 330 and converges towards the middle, which can effectively adjust the position of the bottle back and forth.
[0051] The left and right fine adjustment mechanism 400 includes the following parts: its square frame 2 410 is fixed to the inner wall of the conveying unit 110, an electric push rod 420 is fixedly connected to the bottom end of the square frame 2 410, the U-shaped frame 3 430 is fixed to one end of the electric push rod 420 and slides into the sliding hole 3 113, its inclined frame 2 440 slides inside the sliding hole 1 111, an elastic push rod 2 441 is fixedly connected to one end of the inclined frame 2 441, and a rubber pad 442 is fixedly connected to one end of the elastic push rod 2 441. By pushing the U-shaped frame 3 430 with the electric push rod 420, the inclined frames 2 440 on both sides are squeezed, causing the rubber pad 442 to converge towards the middle, thus completing the left and right adjustment. Together with the front and rear fine adjustment mechanism 300, it can solve the problem that traditional positioning devices cannot correct position deviations in a timely and accurate manner, so that the filling head and the bottle mouth can be accurately aligned.
[0052] The leak-proof mechanism 500 includes the following parts: two sets of L-shaped frames 510 are fixed to the top wall of the conveying unit 110, and a third inclined frame 511 slides between the inner walls of one set of L-shaped frames 510. A spring 516 is fixedly connected to one end of the third inclined frame 511, and a block 515 is fixed between the inner walls of the one set of L-shaped frames 510 and fixed to one end of the spring 516. A rotating seat 512 is fixed to the outer wall of the third inclined frame 511, and a rotating rod 513 is rotatably connected to the rotating seat 512. The rotating rod 513 is rotatably connected to a rotating... The second seat 514 has a ring frame 520 fixed between the outer walls of the two rotating seats 514. The square rod 521 slides on the outer wall of the L-shaped frame 510 and is fixed to the outer wall of the ring frame 520. The hopper 530 is detachably connected to the ring frame 520. The U-shaped frame 430 moves upward under the influence of the electric push rod 420 and contacts the inclined frame 511. The inclined frames 511 on both sides squeeze and drive the hopper 530 downward to accurately insert it into the bottle mouth. This design effectively prevents leakage caused by misalignment of the bottle mouth during filling.
[0053] Specifically, during operation, the bottle is conveyed by the conveying unit 110 to the filling mechanism 200. The front-to-back fine-tuning mechanism 300, driven by the motor 311, rotates the threaded rod 312 to engage with the square plate 313, causing the square plate 313 to move. This causes the two slide rails 314 to move along the inside of the sliding hole 111, passing through both sides of the bottle. One end of the slide rail 314 moves until it contacts the inclined surface of the inclined frame 330, causing the two slide rails 314 to converge towards the center, adjusting the position of the bottle. Then, the electric push rod 420 pushes the U-shaped frame 430, causing the inclined frame 440 to be compressed, which in turn causes the rubber pads 442 on both sides to move towards the center. The U-shaped frame 430 moves upward and contacts the bottle, adjusting the bottle left and right. Then, the U-shaped frame 3 430 continues to move upward and contacts the inclined frame 3 511. The inclined frame 3 511 is squeezed and slides to the side of the L-shaped frame 510, causing the hopper 530 to slide downward along the L-shaped frame 510 and accurately insert into the bottle mouth. The filling mechanism 200 drives the bottle that is limited to be filled. After filling is completed, the motor 311 and the electric push rod 420 drive the front and rear fine adjustment mechanism 300, the left and right fine adjustment mechanism 400 and the anti-leakage mechanism 500 to move to the original state, releasing the bottle from the limit. The conveying unit 110 sends it out. Example 1
[0054] like Figure 2-3As shown, in this embodiment, the front and rear fine-tuning mechanism 300 includes the following parts: its fixing frame 310 is fixed to the outer wall of the conveying unit 110, and the motor 311 is fixed to the outer wall of the fixing frame 310. A threaded rod 312 is fixedly connected to the rotating shaft of the motor 311. Its square plate 313 is screwed onto the outer wall of the threaded rod 312, and two slide rails 314 are provided, both of which slide on the outer wall of the square plate 313. The second U-shaped frame 340 is fixed to the outer wall of the conveying unit 110, and its outer wall is rotatably connected to one end of the threaded rod 312. The square frame 320 is provided in two parts, which are fixed to the inside of the conveying unit 110 on both sides of the filling mechanism 200. An elastic push rod 321 is fixedly connected to the square frame 320. The U-shaped frame 322 is fixed to one end of the elastic push rod 321 and is slidably inserted into the sliding hole 112. There are two sliders 323, which are fixed to both ends of the U-shaped frame 322. The outer wall of the slider 323 is slidably inserted into the inside of the slide rail 314. A set of inclined frames 330 is provided and fixed to the outer wall of the conveying unit 110.
[0055] In this embodiment, the two slide rails 314 in the front and rear fine-tuning mechanism 300 move through both sides of the bottle, with one end contacting the inclined frame 330 and converging towards the center, which can effectively adjust the position of the bottle. This solution can accurately correct the positional deviation of the glass bottle caused by factors such as vibration and speed changes during the conveying process. The front and rear fine-tuning mechanism 300 can move the bottle to a position close to the valve of the filling mechanism 200. In conjunction with the left and right fine-tuning mechanism 400, the bottle is stably aligned with the filling center, which greatly improves the positioning accuracy. By setting a slider 323 to slide with the slide rail 314, the slider 323 can be inserted into the slide rail 314 during the sliding process to ensure the movement stability of the slide rail 314 and effectively improve the accuracy of the position adjustment.
[0056] like Figure 2 and Figure 4 As shown, in this embodiment, the left and right fine adjustment mechanism 400 includes the following parts: its square frame 410 is fixed to the inner wall of the conveying unit 110, an electric push rod 420 is fixedly connected to the square frame 410, a U-shaped frame 430 is fixed to one end of the electric push rod 420 and is slidably inserted into the sliding hole 113, its inclined frame 440 slides inside the sliding hole 111, an elastic push rod 441 is fixedly connected to one end of the inclined frame 440, and a rubber pad 442 is fixedly connected to one end of the elastic push rod 441.
[0057] In practical implementation, the electric push rod 420 pushes the U-shaped frame 430, causing the two inclined frames 440 on both sides to be compressed, which in turn causes the rubber pads 442 to converge towards the center, completing the left and right adjustment. Combined with the front and rear micro-adjustment mechanism 300, this solves the problem that traditional positioning devices cannot promptly and accurately correct positional deviations, ensuring precise alignment between the filling head and the bottle mouth. This effectively avoids problems such as uneven filling volume and liquid spillage, significantly improving the quality of the filled product, reducing material waste, and lowering the defect rate. Furthermore, it can achieve precise positioning for glass bottles of different shapes, no longer limited by differences in bottle shape, overcoming the shortcomings of traditional positioning devices that cannot effectively and accurately position all shapes of glass bottles, whether conventional cylindrical glass bottles or not. Whether it's glass bottles or irregularly shaped bottles, this positioning mechanism can accurately adjust their position, expanding the applicability of the filling machine and improving the versatility of the filling production line. Companies can meet different packaging needs without frequent equipment replacements, reducing equipment procurement and maintenance costs. Furthermore, considering the smooth surface of glass bottles and their susceptibility to displacement under pressure, the coordinated adjustment of the front-to-back micro-adjustment mechanism 300 and the left-to-right micro-adjustment mechanism 400 limits and fixes the bottle from multiple dimensions (front-to-back, left-to-right). During the filling process, the bottle remains stable and will not shift due to slight pressure or vibration, ensuring the stability of the entire filling process and further guaranteeing consistent filling quality. Example 2
[0058] like Figure 5-6 As shown, in this embodiment, the leak prevention mechanism 500 includes the following parts: two sets of L-shaped frames 510 are provided and fixed to the top wall of the conveying unit 110, and the inclined frame three 511 slides between the inner walls of one set of L-shaped frames 510. A spring 516 is fixedly connected to one end of the inclined frame three 511. The block 515 is fixed between the inner walls of one set of L-shaped frames 510 and fixed to one end of the spring 516. The rotating seat one 512 is fixed on the outer wall of the inclined frame three 511. A rotating rod 513 is rotatably connected to the rotating seat one 512, and a rotating seat two 514 is rotatably connected to the rotating rod 513. The ring frame 520 is fixed between the outer walls of the two rotating seats two 514. The square rod 521 slides on the outer wall of the L-shaped frame 510 and is fixed to the outer wall of the ring frame 520. The hopper 530 is detachably connected to the ring frame 520.
[0059] In practice, the U-shaped frame 430 moves upward under the influence of the electric push rod 420 and contacts the inclined frame 511. The inclined frames 511 on both sides squeeze and drive the hopper 530 downward to accurately insert it into the bottle mouth. This design effectively prevents leakage caused by misalignment of the bottle mouth during filling. It also avoids liquid splashing outside the bottle due to abnormal hydraulic pressure when opening or closing the valve. This not only reduces material waste but also keeps the filling production line clean and hygienic, improves the production environment, reduces the risk of corrosion damage to the equipment caused by liquid leakage, and extends the service life of the equipment. In addition, the square rod 521 slides with the L-shaped frame 510, which allows the hopper 530 to slide smoothly and effectively improves the stability of operation.
