Description

Technical Field

[0001] This utility model relates to the field of oral liquid filling production technology, and in particular to a positioning structure for oral liquid filling. Background Technology

[0002] The positioning structure for oral liquid filling is a key component used to fix the position of the bottle in the automated production of oral liquids. Its main function is to fix the oral liquid bottle in the filling process to ensure that the oral liquid does not shake during filling and to avoid leakage, overflow or uneven filling caused by bottle shaking and displacement.

[0003] Traditional positioning structures often employ independent clamping of individual bottles or segmented positioning methods, requiring individual clamping of each bottle or group of bottles. When the placement tray has multiple placement slots, multiple clamping mechanisms need to be triggered in stages, making the positioning process cumbersome and time-consuming, with the time consumption increasing as the number of bottles increases. Furthermore, due to differences in the actions of each clamping mechanism, problems such as asynchronous positioning and uneven clamping force can easily occur, resulting in some bottles being fixed in different positions. This not only affects filling accuracy but also requires frequent machine stops for adjustments, severely restricting filling efficiency and making it difficult to adapt to the demands of high-speed, high-volume oral liquid production. Utility Model Content

[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a positioning structure for oral liquid filling. This solves the problems that existing oral liquid filling positioning structures require multiple operations, have a cumbersome and time-consuming positioning process, and are prone to bottle displacement due to asynchronous clamping, which affects filling accuracy and efficiency.

[0005] This utility model also provides a positioning structure for filling oral liquids as described above, comprising: a working plate, a can body fixedly connected to the upper surface of the working plate, a filling head connected to the front surface of the can body, a placement plate rotatably connected to the upper surface of the working plate, a plurality of placement slots arranged around the circumferential edge of the placement plate, the filling head being located above the placement plate and being able to align and cooperate with only one placement slot at a time in the working state, and a synchronous clamping and positioning component being provided on the placement plate.

[0006] According to the positioning structure for oral liquid filling of the present invention, the synchronous clamping and positioning component includes: multiple sliding grooves and multiple sliding rods. The multiple sliding grooves are equidistantly arranged around the placement tray, and the multiple sliding rods are slidably connected to the interior of the multiple sliding grooves. One end of each of the multiple sliding rods is fixedly connected to a soft clamping plate, and the soft clamping plate is movably connected to the interior of the placement groove.

[0007] According to the positioning structure for oral liquid filling of this utility model, the synchronous clamping and positioning component further includes: a traction ring and a plurality of traction rods. The plurality of traction rods are respectively fixedly connected to the upper surfaces of the plurality of slide rods. The traction ring is rotatably connected to the upper surface of the placement tray. The traction ring is provided with a plurality of traction grooves arranged equidistantly around it. The plurality of traction rods are respectively slidably connected to the interior of the plurality of traction grooves. The traction grooves are arc-shaped.

[0008] According to the positioning structure for oral liquid filling of this utility model, a stepper motor is fixedly connected to the upper surface of the placement tray, a connecting frame is fixedly connected to the upper surface of the stepper motor, and the lower surface of the connecting frame is fixedly connected to the top of the traction ring.

[0009] According to the positioning structure for oral liquid filling of this utility model, a second stepper motor is embedded in the working plate, and the placement tray is fixedly connected to the output end of the second stepper motor.

[0010] Beneficial effects:

[0011] The positioning structure for oral liquid filling in this technical solution uses an arc-shaped traction groove that slides with the traction rod. When the traction ring rotates, it can simultaneously push all the sliding rods toward the center of the placement groove, ultimately achieving synchronous clamping of all the filling bottles. The entire positioning process does not require multiple operations, simplifying it from "multi-step decentralized positioning" to "one-step centralized positioning". This significantly reduces the operation process and time consumption of the positioning link, avoiding the inefficiency of repeated triggering and waiting in the traditional mode.

[0019] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0020] Reference Figure 1-4 This utility model provides a positioning structure for filling oral liquids, which includes: a working plate 5, a can 4 fixedly connected to the upper surface of the working plate 5, a filling head 1 connected to the front surface of the can 4, a placement tray 3 rotatably connected to the upper surface of the working plate 5, a plurality of placement slots 2 arranged around the circumferential edge of the placement tray 3, and the filling head 1 located above the placement tray 3 and can only align and cooperate with one of the placement slots 2 at a time in the working state.

[0021] Considering the need to stably clamp the bottles in the placement slot 2 and avoid damage to the bottles during clamping, a synchronous clamping and positioning component is provided on the placement tray 3. The synchronous clamping and positioning component includes: multiple sliding grooves 14 and multiple sliding rods 13. The multiple sliding grooves 14 are equidistantly arranged around the placement tray 3, and the multiple sliding rods 13 are slidably connected to the inside of the multiple sliding grooves 14. One end of each of the multiple sliding rods 13 is fixedly connected to a soft clamp 10. The soft clamp 10 is movably connected to the inside of the placement slot 2. The sliding grooves 14 on the placement tray 3 provide a sliding path for the sliding rods 13. The soft clamp 10 at one end of the sliding rod 13 moves with the sliding rod 13 in the sliding groove 14 and can extend into the placement slot 2 to contact the bottles. The bottles are clamped by the movement of the soft clamp 10 driven by the sliding rod 13. The material of the soft clamp 10 can buffer the clamping force, ensuring that the bottles are stable and do not shift, and preventing the bottles from being damaged by clamping.

[0022] Considering the need to achieve synchronous clamping of all filled bottles and avoid the inefficiency caused by multiple clamping operations, the synchronous clamping and positioning component also includes: a traction ring 7 and multiple traction rods 12. The multiple traction rods 12 are fixedly connected to the upper surfaces of multiple sliding rods 13. The traction ring 7 is rotatably connected to the upper surface of the placement tray 3. Multiple traction grooves 11 are arranged equidistantly around the traction ring 7. The multiple traction rods 12 are slidably connected inside the multiple traction grooves 11. The traction grooves 11 are arc-shaped. When the traction ring 7 rotates, the arc-shaped traction grooves 11 on it drive the traction rods 12 that are slidably connected to it to move. The traction rods 12 drive the sliding rods 13 to slide along the sliding grooves 14, thereby making all the soft clamps 10 synchronously approach the bottle body, realizing synchronous clamping of multiple bottles without the need for multiple operations, greatly simplifying the positioning process, improving clamping efficiency, and ensuring that the clamping force and position of each bottle are consistent.

[0023] In summary, the improvement of this embodiment lies in:

[0024] The arc-shaped traction groove 11, through its sliding engagement with the traction rod 12, can simultaneously push all the sliding rods 13 toward the center of the placement groove 2 when the traction ring 7 rotates, thus achieving synchronous clamping of all the filling bottles. The entire positioning process does not require multiple operations, simplifying it from "multi-step distributed positioning" to "one-step centralized positioning," significantly reducing the operation process and time consumption of the positioning link, and avoiding the inefficiency of repeated triggering and waiting in the traditional mode.

[0025] Based on the above, other structures also need to be disclosed in detail, such as:

[0026] Considering the need to provide stable power to the traction ring 7 to ensure its precise rotation for driving synchronous clamping, a stepper motor 8 is fixedly connected to the upper surface of the placement plate 3. A connecting frame 6 is fixedly connected to the upper surface of the stepper motor 8, and the lower surface of the connecting frame 6 is fixedly connected to the top of the traction ring 7. The stepper motor 8 fixed on the placement plate 3 drives the connecting frame 6 to rotate through its output end. The connecting frame 6 is fixed to the traction ring 7, thereby driving the traction ring 7 to rotate precisely on the placement plate 3, providing controllable and precise power to the traction ring 7, ensuring the stability of the rotation angle and speed of the traction ring 7, ensuring the precise and reliable synchronous clamping action, and avoiding clamping deviation.

[0027] Considering the need to drive the placement tray 3 to rotate precisely and intermittently to ensure that the placement slots 2 are accurately aligned with the filling head 1 in sequence, a stepper motor 9 is embedded in the working plate 5. The placement tray 3 is fixedly connected to the output end of the stepper motor 9. The output end of the stepper motor 9 embedded in the working plate 5 is fixed to the placement tray 3. The stepper motor 9 can drive the placement tray 3 to rotate intermittently according to a preset program. Each time it rotates to a specified angle, it aligns one placement slot 2 with the filling head 1, realizing the precise intermittent rotation of the placement tray 3. This ensures that each placement slot 2 can be accurately aligned with the filling head 1, providing a guarantee for subsequent precise filling and improving the orderliness and accuracy of the overall filling process.

[0028] Stepper motor 1 (8) and stepper motor 2 (9) are specifically: an actuator that converts electrical pulse signals into angular or linear displacement. Each time a pulse signal is input, the motor will rotate a fixed angle (step angle) in a set direction. By controlling the number, frequency and direction of the pulses, the rotation angle, speed and direction of the motor can be precisely controlled. This is an existing mature technology and is well known to those in this field, so it will not be described in detail in this document.

[0029] Working principle: The working plate 5 serves as the basic supporting component, and the tank 4 fixed on it stores the liquid medicine to be filled. The liquid medicine is injected into the bottle through the filling head 1 on the front surface of the tank 4.

[0030] Bottles are placed sequentially into multiple placement slots 8. Stepper motor 8 on placement tray 3 is started, driving traction ring 7 to rotate via connecting frame 6. Arc-shaped traction groove 11 on traction ring 7 moves synchronously. Multiple traction rods 12 slidably connected to traction groove 11 slide in the groove, thereby driving slide rod 13 fixed thereto to move along slide groove 14 toward the center of placement slot 2. Soft clamp 10 at one end of slide rod 13 extends into placement slot 2 simultaneously, forming a stable clamp for the bottles in the slot.

[0031] The stepper motor 29 embedded on the work plate 5 drives the placement plate 3 to rotate precisely and intermittently, so that the multiple placement slots 2 on the periphery of the placement plate 3 are aligned and matched with the filling head 1 in sequence for filling into the bottle. Only one placement slot 2 is in the filling position at a time.

[0032] After filling is completed, stepper motor 8 rotates in the reverse direction, traction ring 7 drives each component to reset, soft clamp 10 releases the bottle body, and then stepper motor 9 drives the placement plate 3 to rotate to the next station, completing the entire "positioning-conveying-filling-resetting" cycle process, realizing efficient and accurate positioning and filling of oral liquid bottles.

[0033] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
