Description

Technical Field

[0001] The embodiments of this utility model relate to the field of film production equipment technology, specifically to an automatic material dispensing and weighing device for film production. Background Technology

[0002] In the film manufacturing industry, the film production process involves several key stages, with material sorting and weighing being an indispensable one. After the film is formed, it needs to be sorted according to specific specifications and weights to meet the needs of subsequent production or sales. However, in current technology, the sorting and weighing of the formed film mainly relies on manual operation.

[0003] Manual material sorting and weighing has many drawbacks. Firstly, manual operation is inefficient and cannot meet the demands of large-scale industrial production. As film production scales up, the requirements for speed and accuracy in material sorting and weighing become increasingly stringent, and manual operation is clearly inadequate for this trend. Secondly, manual sorting and weighing makes it difficult to distinguish and select defective products. In the film production process, some defective products are inevitable. These defective products may differ from qualified products in thickness, density, surface quality, etc., resulting in different weights. However, when sorting and weighing manually, relying solely on visual observation and manual weighing makes it difficult to accurately and quickly identify defective products, easily mixing them with qualified products and affecting the quality of subsequent products and the production process. Utility Model Content

[0004] To overcome the above-mentioned defects, embodiments of this utility model provide an automatic material sorting and weighing device for film production, which solves the technical problem in the prior art where the finished film is manually sorted and weighed, making it difficult to distinguish and select defective products.

[0008] A material discharge frame is provided on the frame and located directly below the discharge port;

[0009] The discharge port can lead to the dropping frame after the swinging component swings, so as to guide the unqualified film entering from the feed port into the dropping frame.

[0010] For example, in at least one embodiment of the present invention, an automatic material dispensing and weighing device for film production includes a material dispensing component that further comprises:

[0011] A swing drive component is mounted on the frame and is used to drive the swing component to swing.

[0012] For example, in an automatic material dispensing and weighing device for film production provided in at least one embodiment of this utility model, the detection component includes:

[0013] A light-transmitting plate is horizontally arranged on the frame, with its top surface flush with the upper surface of the conveyor belt;

[0015] A visual inspection camera is mounted on the frame and located directly above the light-transmitting plate, used to acquire visual images of the film.

[0016] For example, in an automatic material dispensing and weighing device for film production provided in at least one embodiment of this utility model, the detection component further includes:

[0017] The first roller group includes two parallel first pressure rollers, which are rotatably connected above the conveyor belts at both ends of the light-transmitting plate to press the film onto the light-transmitting plate.

[0018] For example, in at least one embodiment of the present invention, an automatic material dispensing and weighing device for film production includes the following weighing components:

[0019] A material storage enclosure is provided on the frame and located below the conveyor belt, and a discharge port is provided on the side of the material storage enclosure away from the material distribution component;

[0020] A weighing sensor is connected to the bottom of the storage enclosure and is used to detect the weight of the film inside the storage enclosure.

[0021] A discharge component is provided below the storage enclosure and is used to discharge several films from the discharge port.

[0022] For example, in an automatic material dispensing and weighing device for film production provided in at least one embodiment of this utility model, the weighing component further includes:

[0023] A sealing plate, which is slidably connected to the material storage enclosure, is arranged such that it can open or close the discharge port after sliding.

[0024] A sliding drive component is disposed on the material storage enclosure and is used to drive the sealing plate to slide.

[0025] For example, in an automatic material dispensing and weighing device for film production provided in at least one embodiment of this utility model, the weighing component further includes:

[0026] The second roller group includes two vertically arranged second pressure rollers, which are rotatably connected to the frame and located between the material distribution assembly and the material storage enclosure, for feeding the film on the conveyor belt into the material storage enclosure.

[0027] For example, in an automatic material dispensing and weighing device for film production provided in at least one embodiment of the present invention, the detection component, the material dispensing component, and the weighing component together form a material dispensing unit, and multiple material dispensing units are arranged side by side on the frame along a direction perpendicular to the film conveying direction.

[0030] In this invention, the device, through the coordinated arrangement of a frame, detection components, material distribution components, and weighing components, utilizes a conveyor belt to connect these components, forming a continuous automated production line. This replaces the traditional manual material distribution and weighing operations, significantly improving production efficiency. The hinged design of the swinging component in the material distribution component allows it to swing around an axis perpendicular to the conveying direction. By changing the position of the discharge port, it separates qualified and unqualified films. The placement of the drop box corresponding to the discharge port allows for precise collection of defective products, solving the technical problem of the difficulty in manually distinguishing defective products. The linkage between the detection and material distribution components enables the films to undergo quality inspection and sorting simultaneously during conveying, preventing defective products from entering the subsequent weighing stage and ensuring the uniformity of the weighed material's quality.

In addition, the mechanical structure of the material sorting component is simple and reliable. Material sorting is achieved by switching the position of the swinging component. The action response is rapid, which can effectively improve sorting efficiency, reduce the mixing of defective and qualified products, and thus improve the quality of subsequent products and the standardization of the production process.

[0038] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0039] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product.

[0043] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0044] like Figures 1-2 As shown, an automatic material dispensing and weighing device for film production according to an embodiment of the present invention is illustrated, including a frame 1, a detection component 2, a material dispensing component 3, and a weighing component 4, which are connected in sequence by a conveyor belt. The frame 1 serves as a supporting foundation, and a support frame for supporting the conveyor belt is horizontally arranged on its top. The conveyor belt is arranged in a straight line along the film conveying direction and passes through the bottom of the detection component 2, the material dispensing component 3, and the weighing component 4.

[0045] The inspection component 2 is installed at the front end of the frame 1 and includes an inspection station arranged above the conveyor belt for quality inspection of the film. The feeding component 3 is located behind the inspection component 2. Its core structure is a swinging component 31, which is hinged to the support columns on both sides of the frame 1. The swinging direction is perpendicular to the film conveying direction, allowing the swinging component 31 to swing in a vertical plane. The swinging component 31 has a groove-shaped structure. The end near the inspection component 2 forms an inlet 311, which connects to the output end of the conveyor belt so that the film can enter the swinging component 31 from the conveyor belt. The end near the weighing component 4 forms an outlet 312. Under normal conditions, the outlet 312 is aligned with the subsequent conveyor belt, so that qualified film can continue to be conveyed to the weighing component 4 along the conveyor belt. The material drop frame 32 is fixedly installed on the frame 1, and its opening is directly below the discharge port 312. When the swinging component 31 swings, the position of the discharge port 312 shifts and opens toward the material drop frame 32, thereby guiding the defective film to fall into the material drop frame 32.

[0046] The workflow is as follows: The film is conveyed from the front-end equipment to the detection component 2. The film that is qualified after detection enters the feed port 311 of the sorting component 3 along the conveyor belt. At this time, the swinging component 31 is in the initial position and the discharge port 312 is aligned with the subsequent conveyor belt. The film continues to be conveyed to the weighing component 4 for weighing through the discharge port 312. If the film is unqualified after detection, the control system triggers the swinging component 31 of the sorting component 3 to swing around the hinge axis, so that the discharge port 312 is offset above the drop frame 32. The unqualified film enters the swinging component 31 from the feed port 311 and falls into the drop frame 32 through the discharge port 312, realizing the sorting of defective products. The qualified film continues to be conveyed to the weighing component 4, completing the automated process of sorting and weighing.

[0047] This device, through the coordinated arrangement of frame 1, detection component 2, material distribution component 3, and weighing component 4, utilizes a conveyor belt to connect each component, forming a continuous automated production line. This replaces the traditional manual material distribution and weighing operations, significantly improving production efficiency. The hinged design of the swing component 31 in the material distribution component 3 allows it to swing around an axis perpendicular to the conveying direction. By changing the position of the discharge port 312, it separates qualified and unqualified films. The drop frame 32, corresponding to the discharge port 312, accurately collects defective products, solving the technical problem of manual differentiation of defective products. The linkage between detection component 2 and material distribution component 3 enables simultaneous quality inspection and sorting of films during conveying, preventing defective products from entering the subsequent weighing stage and ensuring the uniformity of the weighed material quality. The continuous conveying function of the conveyor belt ensures the orderly flow of films between components, reducing manual intervention and labor intensity. Simultaneously, automated control improves the accuracy and stability of material distribution and weighing, adapting to the needs of large-scale industrial production. In addition, the mechanical structure of the material sorting component 3 is simple and reliable. Material sorting is achieved by switching the position of the swing component 31. The action response is rapid, which can effectively improve sorting efficiency, reduce the mixing of defective and qualified products, and thus improve the quality of subsequent products and the standardization of the production process.

[0048] like Figure 3 As shown, the material distribution assembly 3 also includes a swing drive component 33, which is mounted on the frame 1. Its output end is connected to the hinge shaft of the swing component 31. The swing drive component 33 can be driven by a motor via a crank-connecting rod mechanism. The motor's output shaft is connected to the crank via a coupling, the other end of the crank is hinged to a connecting rod, and the other end of the connecting rod is fixed to the hinge shaft of the swing component 31. The rotation of the motor drives the swing component 31 to reciprocate around the hinge shaft. Alternatively, it can be driven by a cylinder. The cylinder body is fixed to the frame 1, and the piston rod is connected to the hinge shaft of the swing component 31 via a connecting plate. The angle adjustment of the swing component 31 is achieved through the extension and retraction of the cylinder.

[0049] During the workflow, when the detection component 2 determines that the film is unqualified, the control system triggers the swing drive component 33 to move: the motor drives the crank connecting rod mechanism to swing the swing component 31 towards the dropping frame 32, or the cylinder piston rod extends to push the swing component 31 to deflect, so that the discharge port 312 is aligned with the dropping frame 32; when the qualified film passes through, the swing drive component 33 resets, and the discharge port 312 returns to the position aligned with the subsequent conveyor belt.

[0050] The oscillating drive component 33 automates the oscillation motion of the material distribution assembly 3, replacing traditional manual operation and improving the response speed and accuracy of material distribution. The motor or cylinder drive provides stable driving force, ensuring the oscillating component 31 quickly switches positions during high-speed conveying, preventing the mixing of qualified and unqualified films. Through the linkage between the control system and the detection assembly 2, the oscillating drive component 33 can precisely control the oscillation angle based on real-time detection results, achieving accurate sorting of defective products, reducing manual intervention, and improving production efficiency and product quality uniformity. Furthermore, the modular design of the drive component facilitates maintenance and replacement, enhancing the reliability and maintainability of the device.

[0051] like Figure 4 As shown, the detection component 2 includes a light-transmitting plate 21 horizontally mounted on the frame 1. The top surface of the light-transmitting plate 21 is flush with the upper surface of the conveyor belt. A supplementary light 22 is fixedly installed below it, and the light from the supplementary light 22 penetrates vertically upward through the light-transmitting plate 21. A visual inspection camera 23 is mounted on the frame 1 above the light-transmitting plate 21. The lens axis of the camera is perpendicular to the surface of the light-transmitting plate 21 and is used to capture visual images of the film. The supplementary lights 22 are arranged in a circular array, evenly distributed around the central area of ​​the light-transmitting plate 21 to ensure uniform illumination on the film surface. A light shield is provided between the camera and the light-transmitting plate 21 to prevent ambient light from interfering with the detection.

[0052] In the workflow, the film is conveyed to the top of the light-transmitting plate 21 via a conveyor belt, the fill light 22 is turned on to illuminate the film, and the visual inspection camera 23 simultaneously acquires images and analyzes the surface defects, uneven thickness, and other problems of the film through image processing algorithms.

[0053] The combination of the light-transmitting plate 21, the supplementary light 22, and the visual inspection camera 23 forms a high-precision inspection system. Utilizing the light-transmitting characteristics of the light-transmitting plate 21, the supplementary light 22 evenly illuminates the film from below, enabling the camera to clearly capture the internal structure and surface features of the film, effectively identifying defective products. The light shield reduces ambient light interference and improves the stability of the inspection. Compared to manual visual inspection, this inspection method can identify minute defects more quickly and accurately, preventing defective products from entering subsequent processes and improving product quality. The linkage between the inspection component 2 and the sorting component 3 enables simultaneous inspection and sorting, shortening the production cycle and improving overall production efficiency.

[0054] like Figure 4As shown, the detection assembly 2 also includes a first roller group, which consists of two parallel first pressure rollers 24. The two first pressure rollers 24 are rotatably connected to the conveyor belts at both ends of the light-transmitting plate 21. The axis of the first pressure roller 24 is perpendicular to the film conveying direction, and its roller surface contacts the surface of the conveyor belt, pressing the film onto the light-transmitting plate 21. Both ends of the first pressure roller 24 are mounted on the frame 1 through bearing seats. An adjustment mechanism is provided between the bearing seats and the frame 1, which can adjust the height of the first pressure roller 24 in the vertical direction to accommodate films of different thicknesses.

[0055] During the workflow, the film passes under the first pressure roller 24 during the transport process. Under the pressure of the first pressure roller 24, the film is tightly adhered to the light-transmitting plate 21 to ensure that the film remains flat during inspection and to avoid inspection errors caused by film warping.

[0056] The first roller assembly, through physical pressing, maintains a stable planar state of the film during inspection, improving the accuracy of visual inspection. The pressure adjustment function of the spring or pneumatic device can accommodate films of different thicknesses, enhancing the versatility of the device. The height adjustment mechanism of the pressure rollers further optimizes the pressing effect, ensuring that all types of film are tightly bonded to the light-transmitting plate 21, avoiding light refraction or image distortion caused by uneven film, thereby improving the reliability of the inspection system. This structural design is simple, achieving film positioning through mechanical pressing without the need for complex sensors or control systems, reducing equipment costs and maintenance difficulty.

[0057] like Figure 5 As shown, the weighing assembly 4 includes a material storage enclosure 41, which is fixed to the frame 1 and located below the conveyor belt. A discharge port 411 is provided on the side of the enclosure away from the material distribution assembly 3. A weighing sensor 42 is connected to the bottom of the material storage enclosure 41 via a bracket. The output of the weighing sensor 42 is electrically connected to the control system for real-time detection of the weight of the film inside the material storage enclosure 41. A discharge component 43, a belt pusher, is located below the material storage enclosure 41. Its upper surface is aligned with the discharge port 411 of the material storage enclosure 41, and its drive motor is fixed to the frame 1.

[0058] In the workflow, qualified film enters the storage enclosure 41 through the material distribution component 3. The weighing sensor 42 monitors the weight in real time. When the preset weight is reached, the control system triggers the drive motor to start, and the discharge component 43 discharges the film in the storage enclosure 41 from the discharge port 411, completing the weighing and material distribution.

[0059] The combination of the storage enclosure 41, the weighing sensor 42, and the discharging component 43 enables automatic weighing and discharging of the film. The structural design of the storage enclosure 41 facilitates centralized collection of film, while the weighing sensor 42 provides real-time weight data feedback, ensuring accurate weight distribution and preventing weighing precision issues caused by accumulation or blockage. Through the linkage of the control system, weight parameters can be preset according to different production needs, enabling flexible adjustments to the discharging specifications. The coordinated operation of the weighing component 4 and the discharging component 3 reduces manual weighing steps, improves production efficiency and weight control accuracy, and meets the needs of large-scale industrial production.

[0060] like Figure 5 As shown, the weighing assembly 4 also includes a sealing plate 44 slidably connected to the storage enclosure 41. The sliding direction of the sealing plate 44 is consistent with the length direction of the discharge port 411, with one end extending into the discharge port 411 and the other end connected to the sliding drive component 45. The sliding drive component 45 is an electric push rod, the cylinder of which is fixed to the outside of the storage enclosure 41, and the piston rod is hinged to the tail of the sealing plate 44. A guide rail is provided on the storage enclosure 41 along the sliding direction of the sealing plate 44, and the sealing plate 44 cooperates with the guide rail through a slider to ensure smooth sliding.

[0061] During the workflow, when the weight of the film inside the storage enclosure 41 does not reach the preset value, the sliding drive component 45 drives the sealing plate 44 to close the discharge port 411; when the weight reaches the target, the sliding drive component 45 drives the sealing plate 44 to retract and open the discharge port 411, while the discharge component 43 starts to discharge the film.

[0062] The sealing plate 44 and the sliding drive component 45 enable precise control of the discharge port 411, ensuring that the film is not prematurely discharged during the weighing process and improving the accuracy of the material distribution weight. The electric push rod provides a stable driving force, which, together with the guide structure of the guide rail and slider, makes the sliding action of the sealing plate 44 smooth and reliable, avoiding sealing failure or jamming caused by shaking. Through the linkage of the control system, the opening and closing of the sealing plate 44 is synchronized with the data of the weighing sensor 42 in real time, realizing automated batch weighing and material distribution, reducing manual intervention, and improving the continuity and consistency of production.

[0063] like Figure 5 As shown, the weighing assembly 4 also includes a second roller group, which consists of two vertically arranged second pressure rollers 46. The two second pressure rollers 46 are rotatably connected to the frame 1 and located between the material distribution assembly 3 and the material storage enclosure 41. The axis of the second pressure roller 46 is perpendicular to the film conveying direction, and its roller surface is in contact with the surface of the conveyor belt. Synchronous rotation is achieved through gear transmission. Both ends of the second pressure roller 46 are mounted on the frame 1 through bearing seats. A tensioning mechanism is provided between the bearing seats and the frame 1 to adjust the pressure of the second pressure roller 46 on the conveyor belt.

[0064] During the workflow, after the film enters the conveyor belt through the material distribution component 3, the two second pressure rollers 46 of the second roller group rotate synchronously under the action of gear transmission, pressing down and pushing the film into the storage enclosure 41, ensuring that the film enters the storage enclosure 41 smoothly, and avoiding accumulation or retention due to insufficient conveying force.

[0065] The second roller assembly enhances the stability and smoothness of the film entering the storage enclosure 41 through mechanical pressing and pushing. The synchronous rotation design of the gear drive ensures that the two second pressure rollers 46 rotate at the same speed, preventing film stretching or twisting due to speed differences. The pressure adjustment function of the tensioning mechanism can adapt to films of different thicknesses, ensuring moderate pressing force to guarantee both conveying effect and no damage to the film. This structure, in conjunction with the conveyor belt and storage enclosure 41, forms a continuous conveying path, reducing the film's dwell time before weighing and improving overall production efficiency.

[0066] like Figure 1 As shown, the detection component 2, the dispensing component 3, and the weighing component 4 together form a dispensing unit. Multiple dispensing units are arranged side-by-side on the frame 1 along a direction perpendicular to the film conveying direction. The conveyor belts of each dispensing unit are parallel to each other and driven by the same drive system to ensure that the conveying speed of each dispensing unit is consistent. Baffles are provided between adjacent dispensing units to prevent the films from interfering with each other during conveying. The control system is electrically connected to the detection component 2, the dispensing component 3, and the weighing component 4 of each dispensing unit, and can independently control the operating status of each dispensing unit.

[0067] In the workflow, the film is fed into the conveyor belts of multiple sorting units via the main conveyor belt. Each sorting unit simultaneously performs detection, sorting, and weighing operations, achieving multi-line parallel processing. The control system dynamically allocates the film flow rate according to the processing progress of each sorting unit to ensure balanced production.

[0068] The parallel arrangement of multiple sorting units significantly enhances the processing capacity of the equipment. Through multi-line parallel processing, multiple sets of films can be inspected, sorted, and weighed simultaneously, adapting to the needs of large-scale production. The independent control system for each sorting unit allows for flexible adjustment of production parameters, such as setting different inspection standards or sorting weights for different film specifications, enhancing the versatility and adaptability of the equipment. The partition design prevents interference between adjacent sorting units, ensuring the independence and accuracy of each line's processing. This structural design, through its modular layout, facilitates capacity expansion and equipment maintenance, improving the reliability and scalability of the production line.

[0069] The material discharge frame 32 is detachably connected to the frame 1, with its top opening directly below the discharge port 312 of the material distribution assembly 3. Positioning ear plates are provided on both sides of the material discharge frame 32, with through holes on the ear plates. Positioning pins are provided at corresponding positions on the frame 1, passing through the through holes in the ear plates and being secured with nuts. The bottom of the material discharge frame 32 is equipped with casters for easy movement and cleaning after disassembly.

[0070] During the workflow, when it is necessary to clean up defective products or replace the material drop frame 32, loosen the nut, move the material drop frame 32 horizontally along the direction of the positioning pin to detach it from the frame 1, replace it, reinstall it and tighten it.

[0071] The detachable design of the material drop frame 32 facilitates the cleaning and collection of defective products, reducing downtime for maintenance. The connection method using positioning pins and nuts ensures the stability of the material drop frame 32 during installation, preventing shaking or displacement during material distribution. The inclusion of casters further enhances operational convenience, allowing for easy movement of the material drop frame 32 without the need for equipment handling. This structural design enhances the maintainability of the device; by quickly replacing the material drop frame 32, continuous operation of the production line can be maintained, improving production efficiency. Furthermore, the detachable material drop frame 32 facilitates the classification and statistical analysis of defective products, providing data support for production quality analysis.

[0072] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
