Abstract
Description
Technical Field
[0001] This invention relates to the field of winding device technology, and more particularly to a winding device, automatic counting system and method for bagging oral liquid bottle straws. Background Technology
[0002] Oral liquids, as a mainstream dosage form in the pharmaceutical field, require specialized straws for patients to inhale. These straws are typically packaged individually in pouches or in multiple pouches in a row using heat-sealing plastic film (BOPP / CPP). To accommodate automated production, warehousing and logistics, and downstream medicine box assembly needs, the pouched straws must be continuously wound into rolls and accurately counted before being cut and boxed.
[0003] The bagged straws are asymmetrical flexible strips. However, the existing winding devices for bagged oral liquid bottle straws do not have anti-stick / anti-static design. The plastic film and the straw surface are prone to electrostatic adsorption, which can cause adhesion and poor delamination during winding, thus affecting the appearance of the finished bagged straws and the smoothness of feeding. Summary of the Invention

The invention aims to solve the problem that traditional winding devices for bagged straws for oral liquid bottles often result in sticking and poor delamination of the bagged straws during winding, which affects the appearance of the finished product and the smoothness of the feeding.
[0005] To achieve the above objectives, in a first aspect, the present invention provides a winding device for bagging oral liquid bottle straws, comprising a frame, a cutter, a conductive material roller, an electrostatic eliminator, a winding roller, a cooling fan plate, a limiting baffle, and a quick-release baffle; the conductive material roller is rotatably connected to the frame and located on one side of the frame, the winding roller is rotatably connected to the frame and located on one side of the frame, the cutter is fixedly connected to the frame and located on the side of the frame away from the winding roller, the electrostatic eliminator is mounted on the frame, the cooling fan plate is fixedly connected to the frame and located on the side of the frame close to the winding roller, the limiting baffle is fixedly connected to the conductive material roller and located on both sides of the conductive material roller, and the quick-release baffle is detachably connected to the winding roller and located on one side of the winding roller.
[0006] The static eliminator includes an ion fan, a diverter pipe, and a first air outlet plate. The ion fan is fixedly connected to the frame and located on one side of the frame. The first air outlet plate is fixedly connected to the frame and located on the side of the frame near the conductive roller. The diverter pipe is connected to the ion fan and the first air outlet plate, and is located between the first air outlet plate and the ion fan.
[0007] The cooling air plate includes a blower, a cooling box, and a second air outlet plate. The cooling box is fixedly connected to the frame and located on one side of the frame. The second air outlet plate is fixedly connected to the frame and communicates with the cooling box, and is located on the side of the frame near the winding roller. The blower is fixedly connected to the cooling box and is located outside the cooling box.
[0008] The cutter includes a cutter body, a mounting bracket, and a drive rod. The mounting bracket is fixedly connected to the frame and located on the side of the frame away from the winding roller. The drive rod is fixedly connected to the mounting bracket and located at the bottom of the mounting bracket. The cutter body is detachably connected to the drive rod and located on the side of the drive rod away from the mounting bracket.
[0009] The drive rod includes a drive cylinder and a guide rod. The drive cylinder is fixedly connected to the mounting bracket and is located at the bottom of the mounting bracket. The guide rod is fixedly connected to the mounting bracket and is located on both sides of the drive cylinder.
[0010] The quick-release baffle includes a snap-fit ring and a baffle body. The snap-fit ring is fixedly connected to the winding roller and is located on the side of the winding roller away from the frame. The baffle body is snapped into the snap-fit ring and is located on one side of the snap-fit ring.
[0011] In a second aspect, the present invention also provides an automatic counting system for the winding of oral liquid bottle straws after bagging, which is applied to the winding device for oral liquid bottle straws after bagging as described in the first aspect above, including a data acquisition module, an anti-interference module, a counting module and a verification module, wherein the data acquisition module, the anti-interference module, the counting module and the verification module are connected in sequence; The acquisition module obtains the acquisition data by acquiring the signal of the bagged straw passing through the main detection probe and the auxiliary backup probe. The anti-interference module filters out noise generated by workshop frequency conversion, static electricity, and light source fluctuations in the acquired signal based on the anti-shake filtering algorithm.

Used in conjunction with the electrostatic eliminator, it eliminates static electricity on the bagged straw belt. The cooling air plate blows air onto the winding roller to cool the bagged straw belt, preventing residual heat from the heat seal from causing the film surface of the bagged straw belt to melt and stick together. This solves the problem of sticking and poor delamination of the bagged straw belt during winding in traditional oral liquid bottle straw bagging and winding devices, which affects the appearance of the finished straw bag and the smoothness of material feeding.

Detailed Implementation
[0020] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0021] Please see Figures 1 to 3 In a first aspect, the present invention provides a device for winding oral liquid bottle straws after bagging, comprising a frame 1, a cutter, a conductive roller 2, an electrostatic eliminator, a winding roller 3, a cooling fan plate, a limiting baffle 4, and a quick-release baffle; the conductive roller 2 is rotatably connected to the frame 1 and located on one side of the frame 1, the winding roller 3 is rotatably connected to the frame 1 and located on one side of the frame 1, the cutter is fixedly connected to the frame 1 and located on the side of the frame 1 away from the winding roller 3, the electrostatic eliminator is mounted on the frame 1, the cooling fan plate is fixedly connected to the frame 1 and located on the side of the frame 1 close to the winding roller 3, the limiting baffle 4 is fixedly connected to the conductive roller 2 and located on both sides of the conductive roller 2, and the quick-release baffle is detachably connected to the winding roller 3 and located on one side of the winding roller 3.
[0022] In this embodiment, the frame 1 provides support and installation conditions for the other mechanisms. The limiting baffle 4 and the quick-release baffle are used to limit the conveyed bagged straw belt, which can prevent the bagged straw belt from running off-center or overlapping, causing uneven winding ends and dimensional deviations. When the straws are bagged and wound, they are fed through the feeding port. The controller controls the conductive roller 2 to feed the bagged straw belt to the winding roller 3. The winding roller 3 then winds the bagged straw belt. After the number of wound straws reaches the target, the cutter moves down to cut the straws into the bag. Finally, the wound bagged straw belt is removed, thus completing the straw bagging and winding operation. During this process, the electrostatic eliminator blows ion air onto the conveying bagged straw belt to neutralize the static electricity from high-speed friction. The conductive roller 2 is an anodized aluminum roller and is grounded, which can conduct away some of the static electricity. In conjunction with the electrostatic eliminator, it eliminates the static electricity on the bagged straw belt. The cooling air plate blows air onto the winding roller 3 to cool the bagged straw belt and prevent the residual heat from the heat seal from causing the film surface of the bagged straw belt to melt and stick together. This solves the problem that the bagged straw belt will stick and delaminate poorly when the traditional oral liquid bottle straw winding device is winding, which affects the appearance of the finished straw bag and the smoothness of the feeding.
[0023] Furthermore, the static eliminator includes an ion fan 5, a diversion pipe 6, and a first air outlet plate 7. The ion fan 5 is fixedly connected to the frame 1 and located on one side of the frame 1. The first air outlet plate 7 is fixedly connected to the frame 1 and located on the side of the frame 1 near the conductive material roller 2. The diversion pipe 6 is connected to the ion fan 5 and the first air outlet plate 7, and is located between the first air outlet plate 7 and the ion fan 5.
[0024] In this embodiment, the ion fan 5, as the core power component for static electricity elimination, is responsible for ionizing the surrounding air into equal amounts of positive and negative ions. The diversion pipe 6 is used to evenly distribute the ion wind generated by the ion fan 5, ensuring that the ion wind can be smoothly delivered to the first air outlet plate 7. The first air outlet plate 7 is set at the conveying position of the conductive material roller 2, and its air outlet faces the conveying path of the bag straw belt. It can evenly blow the diverted ion wind onto the surface of the bag straw belt during conveying, so as to achieve full contact between ions and static electricity. Combined with the grounding and static electricity conduction effect of the conductive material roller 2, the efficiency and uniformity of static electricity elimination are further improved, avoiding problems such as bag adhesion and dust adsorption caused by local static electricity residue, and ensuring the smooth conveying and winding of the bag straw belt.
[0025] Furthermore, the cooling air plate includes a blower 8, a cooling box 9, and a second air outlet plate 10. The cooling box 9 is fixedly connected to the frame 1 and is located on one side of the frame 1. The second air outlet plate 10 is fixedly connected to the frame 1 and communicates with the cooling box 9, and is located on the side of the frame 1 near the winding roller 3. The blower 8 is fixedly connected to the cooling box 9 and is located outside the cooling box 9.
[0026] In this embodiment, the blower 8 draws outside air into the cooling box 9, which cools the air to ensure that the blown air reaches the preset cooling temperature. The second air outlet plate 10 is connected to the cooling box 9, and the air outlet is directly facing the winding station of the winding roller 3. It can evenly blow the cooled clean air onto the surface of the bagged straw tape being wound, quickly removing the residual heat after the bagged straw tape is heat-sealed, preventing the packaging film from softening or melting due to residual heat, thereby preventing the bagged straw tape from sticking together between layers, and further ensuring the appearance quality of the wound product and the smoothness of subsequent feeding.
[0027] Furthermore, the cutter includes a cutter body 11, a mounting bracket 12, and a drive rod. The mounting bracket 12 is fixedly connected to the frame 1 and is located on the side of the frame 1 away from the winding roller 3. The drive rod is fixedly connected to the mounting bracket 12 and is located at the bottom of the mounting bracket 12. The cutter body 11 is detachably connected to the drive rod and is located on the side of the drive rod away from the mounting bracket 12.
[0028] In this embodiment, the mounting bracket 12 provides stable mounting support for the cutter body 11 and the drive rod. The drive rod provides the power for the cutter body 11 to move up and down. When the number of wrapped bagged straws reaches the preset target value, the controller sends a command to control the drive rod to move, causing the cutter body 11 to move downward and accurately cut the bagged straw strip. The cutter body 11 and the drive rod are detachably connected, which facilitates the subsequent wear and replacement, maintenance and upkeep of the cutter body 11. At the same time, the cutter body 11 of the appropriate specifications can be quickly replaced according to the width and thickness of the bagged straw strip, improving the adaptability and maintenance convenience of the device and avoiding problems such as bag breakage and rough edges during cutting.
[0029] Furthermore, the drive rod includes a drive cylinder 13 and a guide rod 14. The drive cylinder 13 is fixedly connected to the mounting bracket 12 and is located at the bottom of the mounting bracket 12. The guide rod 14 is fixedly connected to the mounting bracket 12 and is located on both sides of the drive cylinder 13.
[0030] In this embodiment, the drive cylinder 13 serves as the power source for the drive rod, and the guide rod 14 is symmetrically arranged on both sides of the drive cylinder 13 to guide and limit the extension and retraction movement of the drive cylinder 13, preventing the drive cylinder 13 from deviating or shaking during movement, thereby ensuring the precise cutting position of the cutter body 11, ensuring that the length and quantity of each roll of bagged straw are consistent, and improving the standardization of the finished product.
[0031] Furthermore, the quick-release baffle includes a snap-fit ring 15 and a baffle body 16. The snap-fit ring 15 is fixedly connected to the winding roller 3 and is located on the side of the winding roller 3 away from the frame 1. The baffle body 16 is snapped into the snap-fit ring 15 and is located on the side of the snap-fit ring 15.
[0032] In this embodiment, the snap-fit ring 15 is fixed to the end of the winding roller 3 to achieve a quick connection between the baffle body 16 and the winding roller 3. The baffle body 16 and the snap-fit ring 15 are snapped together, allowing the installation and removal of the baffle body 16 without the need for tools. This operation is convenient and efficient. It limits the end of the bagged straw during the winding process, further preventing the bagged straw from deviating or overlapping during winding, ensuring that the winding end face is neat and the size meets the standard. At the same time, after winding is completed, the baffle body 16 can be quickly removed, making it easy to remove the rolled bagged straw from the winding roller 3, thus improving production efficiency.
[0033] Please see Figure 4Secondly, the present invention also provides an automatic counting system for the winding of oral liquid bottle straws after bagging, applied to the winding device for bagging oral liquid bottle straws as described in the first aspect above. The system includes a data acquisition module 17, an anti-interference module 18, a counting module 19, and a verification module 20, wherein the data acquisition module 17, the anti-interference module 18, the counting module 19, and the verification module 20 are connected sequentially. The data acquisition module 17 acquires the passing signal of the bagged straws based on a dual-channel acquisition signal from a main detection probe and an auxiliary backup probe, obtaining the acquired data. The anti-interference module 18 filters out noise generated by workshop frequency conversion, static electricity, and light source fluctuations in the acquired signal based on an anti-shake filtering algorithm. The counting module 19 performs the counting accumulation and remaining quantity calculation of the oral liquid bottle straws based on a preset target number of bags per roll and a total counting target. The verification module 20 compares the acquired data from the dual-channel acquisition signal from the main detection probe and the auxiliary backup probe, and combines this with a conveying speed linkage verification to determine abnormalities such as missing bags, stacked bags, and continuous empty material.
[0034] In this embodiment, the main detection probe and the auxiliary backup probe of the acquisition module 17 are installed on the conveyor path of the bagged straws to synchronously acquire signals as the bagged straws pass through. Dual acquisition avoids counting errors caused by the failure of a single probe, ensuring the reliability of the acquired data. The anti-interference module 18 filters the acquired signals using an anti-shake filtering algorithm to eliminate noise signals and avoid over-counting or under-counting problems caused by false triggering, targeting common interference factors in the workshop production environment such as frequency conversion interference, electrostatic interference, and light source fluctuations. The counting module 19 allows users to preset the target number of bags per roll and... The total counting target receives the collected signals after anti-interference processing in real time and completes the counting accumulation calculation. The verification module 20 compares the collected data from the main and auxiliary dual-channel probes. If there is a deviation between the two channels, it performs linkage verification in conjunction with the conveying speed of the conductive material roller 2 and the winding roller 3 to determine whether there are abnormalities such as missing bags, stacked bags, or continuous empty material. Once an abnormality is determined, a signal is immediately sent to the controller to control the winding device to stop and trigger an alarm, so as to prevent unqualified products from flowing into subsequent processes, while ensuring the continuity and stability of production and meeting the high-precision and high-compliance production requirements of the pharmaceutical industry.
[0035] Thirdly, the present invention provides a method for winding oral liquid bottle straws after bagging, which is applied to the oral liquid bottle straw bagging and winding device described in the first aspect above.
