[0002] Oral liquid bottle straws are commonly used consumables in pharmaceutical packaging. They are mainly produced automatically using plastic thermoplastic molding technology. Existing oral liquid bottle straw molding equipment and processing methods typically consist of independent processes such as feeding, heating, stretching, cutting, and manual sampling inspection.

[0003] However, in the existing methods, it is difficult to guarantee the consistency of straw length and the flatness of the cut, which affects the subsequent bagging and usage effect. Furthermore, manual sampling inspection cannot achieve online real-time defect identification and interception, resulting in a high risk of defective products flowing out and a low product qualification rate. Summary of the Invention

[0011] The plastic raw material for the oral liquid bottle straw is fed into the heating box at a uniform speed;

[0012] The straw is thermoformed inside the heating box. The heating box is equipped with a multi-point temperature sensor group. The heating temperature is strictly stabilized within the process setting range by combining temperature sensors with machine vision.

[0047] Please see Figure 4 This invention provides a method for controlling the forming of an oral liquid bottle straw, comprising the following steps:

[0048] S100: The plastic raw material of the oral liquid bottle straw is uniformly conveyed into the heating box 103;

[0049] S200: The straw is thermoformed in the heating box 103. The heating box 103 is equipped with a multi-point temperature sensor group. The heating temperature is strictly stabilized within the process setting range by using a combination of temperature sensors and machine vision.

[0050] S300: In the stretching forming mechanism 104, the stretching speed, stretching stroke and holding pressure shaping parameters are dynamically planned and executed according to the thermoplastic properties of the plastic material and the real-time heating state.

[0051] S400: After the straw is stretched to the desired shape, it is fed under the cutter 107, and then the cutter 107 is controlled to cut the straw to the set length.

[0052] S500: The industrial camera 119 and a dedicated light source acquire images of the straw cut and opening shape in real time. The image processor automatically identifies and judges defects such as cut flatness, opening burrs, bending deformation and length deviation. For unqualified products, the rejection action is triggered immediately and an alarm signal is issued.

[0053] Furthermore, in the step of uniformly conveying the plastic raw material of the oral liquid bottle straw into the heating box 103:

[0054] The material conveying status is monitored in real time by a tension sensor, and the feeding speed is dynamically adjusted.

[0055] Furthermore, the straw is thermoformed inside the heating chamber 103. The heating chamber 103 is equipped with a multi-point temperature sensor group. A method combining temperature sensors and machine vision is used to strictly stabilize the heating temperature within the process-defined range.

[0056] The controller uses a set of temperature sensors to collect real-time temperature field data of the heating zone and the softening and deformation state of the raw materials. Based on the collected information, the controller performs fusion calculations, dynamically adjusts the heating power, and corrects temperature deviations.

[0057] In this embodiment, the plastic raw material for the oral liquid bottle straw is first fed into the heating chamber at a uniform speed. Then, the straw is thermoformed in the heating chamber. The heating chamber is equipped with a multi-point temperature sensor group, and a combination of temperature sensors and machine vision is used to strictly stabilize the heating temperature within the process-set range. Next, in the stretching and forming mechanism, the stretching speed, stretching stroke, and pressure holding parameters are dynamically planned and executed based on the thermoplastic properties of the plastic material and the real-time heating status. After the straw is stretched to the desired shape, it is fed under the cutter, and the cutter is then controlled to cut to the set length. The process begins with a cut; then, an industrial camera and a dedicated light source are used to capture real-time images of the straw cut and opening shape. The image processor automatically identifies and judges defects such as cut flatness, opening burrs, bending deformation, and length deviation. Unqualified products are immediately rejected and an alarm signal is issued. In the above method, multi-sensor fusion closed-loop temperature control ensures stable and controllable heating temperature, avoiding burrs and bending deformation caused by overheating or underheating from the source, thus improving the straw forming quality. Based on real-time monitoring using machine vision, it ensures that the straw cut is flat and the length is consistent, providing high-quality standardized materials for the subsequent bagging process.

[0060] The heating module 121 is used to thermoform the straw inside the heating box 103;

[0061] The stretching module 122 is used in the stretching mechanism 104 to dynamically plan and execute stretching speed, stretching stroke and holding pressure shaping parameters according to the thermoplastic properties of the plastic material and the real-time heating status.

[0062] The cutting control module 123 is used to send the straw under the cutter 107 after it has been stretched into place and reached the shaping condition, and then control the cutter 107 to cut it according to the set length.

[0063] The visual inspection module 124 is used to acquire images of the straw cut and opening shape in real time through the industrial camera 119 and a dedicated light source. The image processor automatically identifies and judges defects such as cut flatness, opening burrs, bending deformation and length deviation. For unqualified products, it immediately triggers rejection action and issues an alarm signal.

[0064] In this embodiment, the feeding module 120 uniformly conveys the plastic raw material of the oral liquid bottle straw to the heating box 103; the heating module 121 thermoforms the straw in the heating box 103; the stretching and forming module 122 dynamically plans and executes the stretching speed, stretching stroke, and pressure holding and shaping parameters in the stretching and forming mechanism 104 according to the thermoplastic properties of the plastic material and the real-time heating status; the cutting control module 123 sends the straw under the cutter 107 after it has been stretched to the desired shape and then controls the cutter 107 to cut it to the set length; the vision inspection module 124 collects images of the straw cut and opening shape in real time through the industrial camera 119 and a dedicated light source, and automatically identifies and judges defects such as cut flatness, opening burrs, bending deformation, and length deviation through the image processor, and immediately triggers rejection action and issues an alarm signal for unqualified products. In the above approach, the modules cooperate with each other and work in sequence to build a closed-loop system of "perception-control-execution", which realizes full-process automation and high-precision control of feeding, heating, stretching, cutting and detection, significantly improving the consistency of straw forming, cut quality and overall production qualification rate.
