Description

Technical Field

[0001] This utility model relates to the feeding mechanism of oral soluble film packaging equipment. Background Technology

[0002] Orally dissolving films are thin, tablet-like oral medications that dissolve in the mouth, typically about the size of a postage stamp. The raw material consists of a composite roll material with a formulation layer laid on a continuous roll base (such as a plastic or paper base film). This material can be fed using an unwinding method. Alternatively, the formulation layer can be directly peeled from the continuous roll base and cut into individual sheets (orally dissolving films). These sheets are then transferred to a packaging machine (such as a four-side sealing packaging machine) using a lifting nozzle for packaging, forming individually packaged orally dissolving films. However, this process is prone to detachment, and the speed is difficult to increase, with inconsistent positioning. Furthermore, directly pulling the detached formulation layer can easily cause breakage. Utility Model Content

[0003] In view of the technical problems existing in the background art, the present invention aims to provide a relatively stable and efficient feeding mechanism for oral dissolving film packaging equipment.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: the feeding mechanism of the oral dissolving film packaging equipment includes a main material unwinding device, a main material traction device, a formulation layer cross-cutting device, and a formulation layer peeling device. The formulation layer peeling device includes a peeling component and a base layer traction component. The base layer traction component is connected to the downstream of the base layer output path at the front peeling point of the peeling component. The main material unwinding device is connected to the main material traction device. A formulation layer cross-cutting device is configured between the main material traction device and the formulation layer peeling device. The peeling component is configured on the material output side of the formulation layer cross-cutting device. A formulation layer unit receiving component is also configured on the front side of the peeling component.

[0005] The following optimizations or supplementary explanations can be made to the above technical solutions.

[0006] For example, the main material unwinding device includes an unwinding motor, and a floating guide roller is provided between the main material unwinding device and the main material traction device. The guide roller is equipped with a position detection sensor, which is connected to the main material unwinding device. The unwinding motor is also connected to the position detection sensor. The main material traction roller is driven by the first motor, and the base traction roller is driven by the second motor. The first motor is a servo motor, the second motor is a servo motor, and the unwinding motor is a servo motor. Each traction roller is also equipped with a pressure roller. The position detection sensor is a linear displacement sensor, and the guide roller is a lifting detection guide roller.

[0007] The feeding mechanism of the oral soluble film packaging equipment also includes a main material slitting device, which includes slitting blades arranged horizontally side by side. The slitting device is positioned between the main material unwinding device and the main material traction device. A guide roller is provided between the slitting device and the main material unwinding device.

[0008] In addition, a material separation device is connected between the slitting device and the main material traction device.

[0009] For example, the material separation device includes at least two separation rollers, with separation grooves distributed on the separation rollers and separation wheels installed on the separation rollers. The separation grooves are located between adjacent separation wheels. The lateral position of the separation wheels on the separation rollers is adjustable. The slitting blade includes a paired upper circular blade and a lower circular blade. The upper circular blade is installed on an upper blade shaft, and the lower circular blade is set on a lower blade shaft. The upper blade shaft and the lower blade shaft are connected by a drive at their ends, and the lower blade shaft is connected by a slitting rotation drive motor.

[0010] For example, the formulation layer transverse cutting device includes a transverse cutting blade for transversely cutting the formulation layer on the main material. The transverse cutting blade is arranged transversely and is set on a cutter roller. A padding roller is arranged below the cutter roller. In the transverse cutting condition, the blade of the transverse cutting blade faces the padding roller below and a base layer gap matching the thickness of the base layer is left between the blade and the padding roller.

[0011] The cutter roller and the padding roller are connected by a drive, and the padding roller is connected by a cross-cutting rotation drive motor; the main material traction device and the base layer traction component are continuous traction structures.

[0012] For example, the formulation layer unit receiving component adopts a bag-making substrate feeding table, which is connected to the packaging equipment.

[0013] Specifically, the peeling component includes a peeling roller, peeling shaft, or peeling plate, which is connected to the front side of the formulation layer cross-cutting device. The bag substrate feeding table includes a flat table, which is connected to the input side of the sealing mechanism of the packaging equipment. An electrostatic generator is configured below the bag substrate feeding table. The rear end of the flat table is the turning end of the bag substrate from bottom to top and then to front. The front and rear positions of the peeling component and / or the formulation layer unit receiving component are adjustable. A base layer winding device is also connected downstream of the output end of the base layer traction component.

[0014] The beneficial effects of this utility model are as follows: In the feeding mechanism of the oral soluble film packaging equipment, the formulation layer on the base layer of the main material is cut laterally from left to right and then peeled away from the base layer. Before the formulation layer is peeled away from the base layer, it always adheres to the base layer and moves along. After the formulation layer is peeled away, it is directly transferred to the formulation layer unit receiving component and supplied to the subsequent packaging equipment, thus avoiding the breakage of the formulation layer during the feeding process. The formulation layer is first cut laterally on the base layer (cutting the entire formulation layer into individual formulation layer units, while the base layer remains continuous) and then peeled away. Before the peeling away, the formulation layer always adheres to the base layer, which is more stable and can also speed up the operation and make it more efficient. This avoids the problem that the formulation layer is easily pulled and broken when it is peeled away from the base layer first and then cut. Moreover, the tension of the entire formulation layer that is peeled away first is not easy to control, making it difficult to speed up production and affecting production efficiency.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the implementation of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0033] Referring to the accompanying drawings, the feeding mechanism of the oral dissolving film packaging equipment in this embodiment can be used in bag making and packaging equipment (e.g., a four-side sealing machine). It includes a main material unwinding device 1, a main material traction device 2, a formulation layer cross-cutting device 3, and a formulation layer peeling device 4. The formulation layer peeling device 4 includes a peeling component 41 and a base layer traction component 42. The base layer traction component 42 is connected downstream of the base layer output path at the front peeling point 411 of the peeling component 41, and peels the material (such as the formulation layer) on the base layer 49 to separate them. This is a mature technology and will not be described in detail.

[0034] The present invention employs the following cooperative structure: The main material unwinding device 1 is connected to the main material traction device 2. The main material unwinding device 1 is used to unwind and output the continuously wound main material 10 (including the formulation layer and the base layer 49), and the main material traction device 2 cooperates to traction and convey the main material 10. A formulation layer transverse cutting device 3 is configured between the main material traction device 2 and the formulation layer peeling device 4. The formulation layer transverse cutting device 3 is used to transversely cut the formulation layer on the base layer 49 of the main material 10, so that the formulation layer on the base layer 49 of the main material 10 is broken into individual formulation layer units 38 (so that each subsequent unit can form an independent package), ensuring that separate formulation layer units 38 are formed during the subsequent peeling process of the formulation layer peeling device 4. The peeling component 41 is configured on the material output side of the formulation layer transverse cutting device 3. The main material 10 undergoes transverse cutting of the formulation layer by the formulation layer transverse cutting device 3 (wherein...). (The base layer 49 remains continuous), then the main material 10 is output and travels to the peeling component 41 to peel the formulation layer from the base layer 49. The base layer traction component 42 is connected downstream of the base layer output path at the front peeling point of the peeling component 41, and pulls the base layer 49 to cooperate in the peeling. The base layer 49 is in a continuous line from the main material unwinding device 1 to the base layer traction component 42. The front side of the peeling component 41 is also equipped with a formulation layer unit receiving component 5, which can receive individual separated formulation layer units 38. After peeling, the individual formulation layer units 38 will be transported to the formulation layer unit receiving component 5 for packaging equipment. The formulation layer is always on the base layer 49 before peeling. The formulation layer is attached to the base layer 49 and is not easy to be pulled and broken until the formulation layer unit 38 is separated from the base layer 49 and transferred to the formulation layer unit receiving component 5 for packaging equipment.

[0035] Its working principle is as follows: the formulation layer moves on the continuous base layer 49. The base layer 49 is moved by the main material unwinding device 1, the main material traction device 2, and the base layer traction component 42. During the movement of the formulation layer with the base layer 49, it is transversely cut in the formulation layer transverse cutting device 3 (the formulation layer on the base layer 49 in the main material 10 is broken to form individual formulation layer units 38, while the base layer 49 remains continuous). Then, the broken formulation layer units 38 move with the base layer 49 to the formulation layer peeling device 4 (at its peeling component 41) to separate the formulation layer from the base layer 49. The peeled formulation layer units 38 are then transported to the formulation layer unit receiving component 5 for supply to the packaging equipment.

[0036] In the feeding mechanism of this oral soluble film packaging equipment, the formulation layer on the base layer 49 of the main material 10 is cut laterally and then peeled off from the base layer. Before the formulation layer is peeled off from the base layer, it always adheres to the base layer. After the formulation layer is peeled off, it is directly transferred to the formulation layer unit receiving component 5 and supplied to the subsequent packaging equipment, thus avoiding breakage of the formulation layer during the feeding process. The formulation layer is first cut laterally on the base layer (cutting the entire formulation layer into individual formulation layer units 38, while the base layer remains continuous) and then peeled off. Before peeling off, the formulation layer always adheres to the base layer, which is more stable and can also speed up the operation and make it more efficient. This avoids the problem that the formulation layer is easily pulled and broken when the formulation layer is peeled off from the base layer 49 first and then cut off. Moreover, the tension of the entire formulation layer that is peeled off first is not easy to control, making it difficult to speed up production and affecting production efficiency.

[0037] Based on the above embodiments, the following optimizations or further explanations can be made.

[0038] The main material traction device 2 includes a main material traction roller 20, and the base layer traction component 42 includes a base layer traction roller 43. The method of using the corresponding traction rollers to traction the continuously rolled material is relatively mature and existing. The material traction linear speed of the main material traction roller 20 and the base layer traction roller 43 is kept consistent, which can ensure that the material between the main material traction device 2 (corresponding to the main material traction roller 20) and the base layer traction component 42 (corresponding to the base layer traction roller 43) is in a stable state, and its tension is also relatively stable. The preparation layer transverse cutting device 3 can more stably and smoothly carry out transverse cutting and separation at the peeling component 41, avoiding interference from other components and devices before and after.

[0039] For example, the main material unwinding device 1 includes an unwinding motor 11, which controls the speed of unwinding. For example, the main material unwinding device 1 has an unwinding shaft 12 (such as an air shaft), which is connected to the unwinding motor 11 to control the speed of unwinding. The main material unwinding device 1 and the main material traction device 2 can also be equipped with a floating guide roller 6 (e.g., floating up and down or swinging). The guide roller 6 is equipped with a position detection sensor 61 (e.g., a linear displacement sensor such as an electronic ruler). The position detection sensor 61 detects the relative position of the guide roller 6 (e.g., its height). The position detection sensor 61 is connected to the main material unwinding device 1, and the unwinding motor 11 is connected to the position detection sensor 61 so that the position detection sensor 61 can feed back the position signal to the main material unwinding device 1. In conjunction with controlling the winding speed (e.g., controlling the speed of the unwinding motor 11 to drive the unwinding shaft 12), the main material unwinding device 1 can output more or less main material, so that the unwinding output is in a relatively stable state. The material (main material) between the main material unwinding device 1 and the main material traction device 2 is in a relatively stable state, and the tension is also relatively stable. This part of the material is also relatively independent and does not easily affect the subsequent cross-cutting and peeling separation. The main material 10 is surrounded by a guide roller 6, which supports and guides the arrangement of the main material. When the main material is unwound and output in large or small quantities, the guide roller 6 will change its position (for example, the lifting position will change). When the position change exceeds the set value, it can cooperate to reduce or increase the unwound output of the main material by the main material unwinding device 1.

[0040] For example, the main material traction roller 20 is connected to the first motor 21, and the base material traction roller 43 is connected to the second motor 44, so as to drive the corresponding traction rollers to rotate and cooperate in traction. In addition, the first motor 21, the second motor 44, and the unwinding motor 11 are all servo motors, and the control technology is relatively mature. Each traction roller (main material traction roller 20 and base material traction roller 43) is also equipped with a pressure roller to press the material onto the corresponding traction roller for smoother traction. For example, the position detection sensor 61 is a linear displacement sensor, and the guide roller 6 is a lifting detection guide roller (i.e., a floating guide roller 6 that lifts up and down). The roller seat of the guide roller 6 can be slidably set on the vertical guide rod 63.

[0041] The feeding mechanism of the oral dissolving film packaging equipment also includes a main material slitting device 7. This device can slit relatively wide materials into narrower widths and can also be used to trim sides (edges). The main material slitting device 7 includes slitting blades 70 arranged laterally side-by-side. The slitting device is positioned between the main material unwinding device 1 and the main material traction device 2. A guide roller 6 can be positioned between the slitting device and the main material unwinding device 1. The guide roller 6 provides overall support and guidance for the main material, resulting in a more rational layout. When the guide roller 6 is a floating type and equipped with a position detection sensor 61, the slitting process can prevent the guide roller 6 from being affected by the slitting process, thus ensuring its operational stability.

[0042] In addition, a material step-by-step separation device 8 is connected between the main material cutting device 7 and the main material traction device 2. The material step-by-step separation device 8 is used to separate the cut materials (multiple narrow strips of material) laterally to each other during the process of travel. The material step-by-step separation device 8 is connected to the path of the material from the cutting device to the main material traction device 2. This can meet the subsequent packaging requirements and avoid the problem of adjacent materials being difficult to package after cutting. For example, four-side sealed packaging bags have sealing edges to prevent adjacent materials from affecting the sealing edges. A progressively separating structure creates a multi-stage, gradual separation effect, allowing for gradual separation and ensuring relatively stable material flow without distortion or deformation that could affect usability. For example, a progressively separating material device 8 includes at least two stages of separating rollers 80 (such as two- or three-stage separating rollers 80). Separating grooves 81 are distributed on the separating rollers 80. After slitting, the material (multiple narrow strips) corresponds to the respective separating grooves 81. The spacing between the separating grooves 81 on different separating rollers 80 varies, with the spacing increasing progressively at each stage. The spacing between the spacing grooves 81 on the first-stage spacing roller 80 is the smallest, and the spacing between the spacing grooves 81 on the subsequent spacing rollers 80 gradually increases. Splitting wheels 82 can be installed on the spacing rollers 80, and the spacing grooves 81 are between adjacent spacing wheels 82. The lateral position (i.e., the axial direction of the spacing rollers 80) of the spacing wheels 82 on the spacing rollers 80 can be adjusted to adjust the size and lateral position of the spacing grooves 81 according to the needs, so as to ensure smooth step-by-step spacing and adapt to materials with different narrow widths.

[0043] The slitting device technology is relatively mature. For example, the slitting blade 70 includes a paired upper circular blade 71 and a lower circular blade 72. The upper circular blade is mounted on the upper blade shaft 73, and the lower circular blade 72 is mounted on the lower blade shaft 74. The upper blade shaft 73 and the lower blade shaft 74 are connected by a transmission (such as a gear meshing transmission). The lower blade shaft 74 is connected by a slitting rotary drive motor 75. The rotary drive motor drives the lower blade shaft 74 to rotate, and the upper blade shaft 73 rotates in conjunction with it. This allows the upper circular blade and the lower circular blade 72 to work together to cut the material between them (the main material 10 includes the base layer 49 and the preparation layer, with the base layer located at the bottom of the preparation layer) to achieve slitting, with relatively good results.

[0044] The formulation layer transverse cutting device 3 includes a transverse cutting blade 30 for transversely cutting the formulation layer on the main material 10. The transverse cutting blade 30 is arranged transversely. The transverse cutting blade 30 can be mounted on the cutter roller 31 and rotates with the cutter roller 31. Multiple transverse cutting blades 30 can be set as needed (e.g., evenly arranged on the cutter roller 31, evenly arranged along the circumference, or evenly distributed). A padding roller 32 is arranged below the cutter roller 31, which is placed under the material (main material including the base layer and formulation layer). The padding roller 32 works in conjunction with the transverse cutting blade 30 on the cutter roller 31 to transversely cut the formulation layer on the base layer of the main material 10 (the base layer remains continuous and unbroken). Under normal operating conditions, the blade edge of the transverse cutting blade 30 faces downwards. The square padding roller 32 has a base layer gap between the blade and the padding roller 32 that matches the base layer thickness. That is, in the cross-cutting working state, the blade of the cross-cutting blade 30 faces downward towards the padding roller 32 below, and there is a gap (i.e., base layer gap) between the blade of the cross-cutting blade 30 and the padding roller 32 below (the roller surface of the padding material). The existence of the base layer gap avoids cutting off the base layer in the main material and ensures that the base layer is in a continuous (unbroken) state. The base layer gap can be equal to, slightly greater than, or slightly less than the base layer thickness. The cutter roller 31 and the padding roller 32 are connected by a transmission (gears can be installed at their ends for transmission). The padding roller 32 is connected to a cross-cutting rotation drive motor, which drives the padding roller 32 to rotate and drive the cutter roller 31 to rotate together. The main material traction device 2 and the base layer traction component 42 are continuous traction structures, which are more efficient and faster. The cross-cutting blades 30 on the rotating cutter roller 31 cooperate to achieve continuous operation. The material tension between the main material traction device 2 and the base layer traction component 42 is stable.

[0045] The formulation layer unit receiving component 5 can receive individual formulation layer units 38. After being peeled off, the individual formulation layer units 38 are conveyed to the formulation layer unit receiving component 5 for supply to the packaging equipment. The formulation layer unit receiving component 5 can be a bag-making substrate feeding table 50. The bag-making substrate feeding table 50 is connected to the packaging equipment (such as a four-side sealing packaging machine). The bag-making substrate 92 (such as a continuous roll film for four-side sealing bags, whose bag body is made by sealing the four sides of the continuous roll film and then cutting) can travel on the bag-making substrate feeding table 50. The bag-making substrate feeding table 50 is connected to the sealing mechanism 9 of the packaging equipment. On the input side (e.g., the rear position) of the four-side sealing mechanism (such as the upper and lower mold closing mechanism), the bag substrate feeding table 50 can be set as a flat table 51. The rear end of the flat table 51 is the turning end of the bag substrate 92 from bottom to top and then to front. During operation, the bag substrate 92 (such as continuous roll film) moves from below the feeding table (flat table 51), around the rear end support of the feeding table, turns to the top of the feeding table, and is conveyed forward to the packaging equipment (such as its sealing mechanism 9) to cooperate with the packaging equipment. At this time, the peeled formulation layer units 38 can be directly received by the bag substrate 92 and enter the packaging equipment (such as its sealing mechanism 9) together with the bag substrate 92 for packaging. The bag substrate feeding table 50 can also be equipped with an electrostatic generator 52 to form electrostatic adsorption on the bag substrate 92 above, so that the formulation layer units 38 are more stable when received by the bag substrate 92 and are less prone to displacement, and the position is more accurate when packaged in the subsequent packaging equipment; the electrostatic generator 52 can be set below the bag substrate feeding table 50.

[0046] The adjustable front and rear positions of the peeling component 41 and / or the formulation layer unit receiving component 5 allow for adjustment of the gap between them, facilitating the adjustment of their relative positions to ensure smooth peeling and receiving of the formulation layer. The peeling component 41 and the formulation layer unit receiving component 5 can be mounted on a support frame 90, which has a perforated channel 91 to facilitate material passage. Furthermore, a base layer winding device 45 (including a winding shaft 451) is connected downstream of the base layer traction component 42 to collect and process the base layer. When peeling other layers (such as the formulation layer) from the base layer (such as a continuous roll of base film or backing paper), peeling components 41, such as peeling rollers / shafts or peeling plates, are used to peel the layer off. The formulation layer continues forward due to its stiffness, detaching from the continuous roll of base layer. The base layer is then wound up by the winding structure. For example, with an angled peeling plate with a sharp angle, the base layer is bent in the opposite direction, and the formulation layer continues forward due to its stiffness, achieving peeling. The input side of the main material traction device 2 and the input side of the base traction component 42 can be equipped with left and right limit blocks 10 to limit the left and right lateral positions of the cut material, so that the material is more accurate during the conveying and traction process. The limit blocks can be adjusted to the left and right positions as needed to meet the requirements of debugging and different material specifications.
