Description

Technical Field

[0001] This utility model relates to the technical field of filling and sealing equipment, and more specifically, it relates to a small-dose inclined horizontal filling, sealing and labeling equipment. Background Technology

[0002] In the pharmaceutical, cosmetics, and food industries, the filling of small-dose vials is widely used. Filling is a critical step in the production process, and its efficiency and quality directly affect the yield and quality of the final product. Currently, automated filling lines are commonly used in the industry, with the conveyor belt being the core component for transporting bottles. Before filling, it is necessary to ensure that the bottles enter the filling station in the correct orientation (e.g., bottle neck upwards, bottle body upright). However, existing filling equipment typically uses horizontal conveyor belts. This structure has the following inherent drawbacks:

[0003] 1. Bottle posture is difficult to guarantee: During the horizontal conveyor belt transport process, bottles may tip over, tilt, or turn due to inertia, vibration, or collisions with each other. Bottles with incorrect posture entering the filling station will cause the filling head to be unable to accurately align with the bottle mouth, resulting in filling failure, liquid splashing, equipment contamination, and other problems, seriously affecting filling quality and production efficiency.

[0004] 2. Reliance on complex correction mechanisms: To address the aforementioned issues, existing technologies typically add independent correction or shaping devices, such as mechanical levers, guide plates, visual inspection, and robotic gripping, to the side of the horizontal conveyor belt or at specific workstations. These additional mechanisms not only increase the complexity and manufacturing cost of the equipment but also occupy valuable production line space. Furthermore, the complex mechanical movements may introduce new instabilities and increase the difficulty and frequency of equipment maintenance.

[0005] There is an urgent need in this field for a solution that can achieve automatic, continuous, and reliable correction and shaping during the bottle conveying process, thereby simplifying equipment structure and improving filling efficiency and quality. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a filling method that can achieve automatic, continuous and reliable correction and shaping, thereby simplifying the equipment structure and improving filling efficiency and quality.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A small-dose inclined horizontal filling, sealing, and labeling device includes a frame, a conveying device, and a filling device. The conveying device is mounted on the frame and is used to transport bottles. The conveying device is inclined upward from left to right, and the filling device is located on the right side where the inclination height is higher. The conveying device includes an inclined base and an inclined conveyor belt mounted on the base. The bearing surface of the conveyor belt is provided with multiple roller assemblies for correcting the posture of the bottles. The roller assembly includes multiple correction rollers arranged parallel to the conveying direction of the conveyor belt, and the axial direction of each correction roller is perpendicular to the conveying direction of the conveyor belt.

[0009] The present invention is further configured such that: the frame is provided with three adjustment devices arranged side by side on the left side of the conveying device, including a longitudinal adjustment mechanism located on the frame and a transverse adjustment mechanism installed on the sliding part of the longitudinal adjustment mechanism. The tail end of the transverse adjustment mechanism extends to the upper right side of the conveying device. The filling device includes a canning component, a sealing component, and a secondary sealing and cooling component, which are respectively assembled at the tail end of the transverse adjustment mechanism.

[0010] The present invention is further configured as follows: the longitudinal adjustment mechanism includes a handwheel, a transmission screw connected to the handwheel, a sliding seat threadedly engaged with the transmission screw, and a guide shaft slidably engaged with the sliding seat; the lateral adjustment mechanism includes a handwheel, a transmission screw connected to the handwheel, the transmission screw being threadedly engaged with the sliding seat, and guide shafts being provided on both sides of the transmission screw, the guide shafts being slidably inserted into the sliding seat.

[0011] The present invention is further configured such that: a positioning component is sleeved on the second guide shaft, the positioning component includes a positioning frame that is driven by a cylinder to move back and forth in the direction of the conveyor belt, and the positioning frame is provided with a plurality of positioning grooves that are adapted to the bottle body.

[0012] The above technical solution has the following advantages.

[0013] 1. Automatic and continuous bottle posture correction improves filling accuracy. Inclined conveyor design: The conveyor belt tilts upward from left to right, and the bottles naturally adhere to the bottom surface of the conveyor belt under the action of gravity, forming a stable posture and reducing phenomena such as tipping, rotation, and deviation; Roller assembly correction: The conveyor belt is equipped with multiple parallel correction rollers, whose axes are perpendicular to the conveying direction, to perform rolling-type micro-adjustment of the bottle posture, achieving continuous, non-rigid, and non-damaging automatic correction;

[0014] 2. Improve filling efficiency and stability. The bottle moves continuously on the inclined conveyor belt, and the positioning component accurately intercepts it at the filling station, achieving a seamless connection between "conveying-positioning-filling" and avoiding the time loss of traditional stop-filling.

[0015] 3. Secondary sealing and cooling assembly: Immediately cools and sets the seal after sealing to prevent deformation or leakage, improve the yield of finished products, and reduce manual intervention;

[0016] 4. Fully automatic calibration, positioning, filling and sealing reduce the frequency of manual debugging and maintenance, making it suitable for small-dose, high-speed production scenarios. Attached Figure Description

[0022] Reference Figures 1 to 4 The embodiments of this utility model will be further described below.

[0023] A small-dose inclined horizontal filling, sealing and labeling device includes a frame 1, a conveying device 2 and a filling device 3. The conveying device 2 is mounted on the frame 1 and is used to convey bottles. The conveying device 2 is inclined upward from left to right. The filling device 3 is located on the right side where the inclination height is higher. The conveying device 2 includes an inclined base 20 and an inclined conveyor belt 21 located on the base 20. The bearing surface of the conveyor belt 21 is provided with a plurality of roller assemblies for correcting the posture of the bottles. The roller assembly includes a plurality of correction rollers 22 arranged parallel to the conveying direction of the conveyor belt 21. The axial direction of each correction roller 22 is perpendicular to the conveying direction of the conveyor belt 21.

[0024] The frame 1 has three parallel adjustment devices 4 on the left side of the conveying device 2. These include a longitudinal adjustment mechanism 40 located on the frame 1 and a transverse adjustment mechanism 41 installed on the sliding part of the longitudinal adjustment mechanism 40. The tail end of the transverse adjustment mechanism 41 extends to the upper right side of the conveying device 2. The filling device 3 includes a filling assembly 30, a sealing assembly 31, and a secondary sealing and cooling assembly 32, which are respectively assembled at the tail end of the transverse adjustment mechanism 41.

[0025] The longitudinal adjustment mechanism 40 includes a handwheel 400, a transmission screw 401 connected to the handwheel 400, a sliding seat 402 threadedly engaged with the transmission screw 401, and a guide shaft 403 slidably engaged with the sliding seat 402. The lateral adjustment mechanism includes a handwheel 410, a transmission screw 411 connected to the handwheel 410, the transmission screw 411 threadedly engaged with the sliding seat 402, and guide shafts 412 are provided on both sides of the transmission screw 411, the guide shafts 412 being inserted into the sliding seat 402 for slidable engagement.

[0026] The guide shaft 412 is fitted with a positioning component 5, which includes a positioning frame 50 driven by a cylinder to move back and forth toward the conveyor belt 21. The positioning frame 50 is provided with a plurality of positioning grooves 51 that are adapted to the bottle body.

[0027] Working principle: The bottle falls into the feeding end of the inclined conveyor belt 21 via a vibratory feeder. Because the conveyor belt 21 is inclined, the bottle's center of gravity automatically moves towards the bottom. Under the combined action of gravity and friction, the bottle immediately forms an initial posture with the bottom against the conveyor belt 21 and the bottle mouth facing upwards. At this time, the correction rollers 22 are in line contact with the bottle, resulting in minimal rolling resistance. The bottle can move synchronously with the belt, achieving automatic correction and conveying. When the bottle is transported to the filling assembly station, the positioning frame 50 descends from the positioning mechanism to position the bottle for the filling process. It is then conveyed to the sealing assembly 31 for the initial sealing process, and then enters the secondary sealing and cooling assembly 32 for a second sealing and cooling process, completing the filling and sealing process for small-dose bottles. A labeling device can also be installed subsequently to directly label the bottles after the filling process.

[0028] A longitudinal adjustment mechanism 40 is added to adjust the height of the filling device 3. By operating handwheel 400, the transmission screw 1 rotates, causing the sliding seat 402 to slide up and down along guide shaft 403, thereby adjusting the height of the lateral adjustment mechanism 41 and thus achieving the height adjustment of the filling device 3. The lateral adjustment mechanism 41 allows for the adjustment of the lateral position of the filling device 3. By operating handwheel 410, the transmission screw 411 rotates and extends / retracts on the sliding seat 402, causing guide shaft 412 to extend and retract, thus adjusting the lateral position of the filling device 3.

[0029] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
