Description

Technical Field

[0001] This utility model relates to the field of double-layer feeding technology, and in particular to an intermittent fixed-length double-layer feeding structure. Background Technology

[0002] In the operation of modern experimental analytical equipment and automated testing instruments, the material feeding process is a crucial component ensuring continuous and efficient operation. With the development of automated processing and biological detection technologies, intermittent feeding structures are increasingly being used in laboratories and production sites to achieve quantitative and fixed-length delivery of reagents, consumables, or membrane tapes, thereby improving the overall automation level of processing and testing. Especially in scenarios requiring repeated feeding and fixed-length cutting, a well-designed feeding structure directly impacts operational efficiency and the stability of test results.

[0003] In existing technologies, common feeding devices typically rely on the cooperation of drive wheels, guide rails, and limiting devices to intermittently transport film belts or other materials at fixed intervals. During this process, the feeding length is controlled by mechanical clamping mechanisms or friction drive structures, combined with manual or semi-automatic shearing methods to complete the cutting. The technical principle mainly relies on the cooperation of drive components and limiting components to ensure feeding accuracy, and achieves continuous batch feeding through repetitive intermittent actions. Although this type of structure can meet the needs of fixed-length conveying to a certain extent, it still suffers from insufficient efficiency in actual operation.

[0004] However, existing feeding methods still have significant drawbacks in practical applications. Traditional feeding structures rely heavily on manual operation to place and cut membrane tapes or reagent consumables. Especially in scenarios such as experimental reaction cups or membrane tape processing, operators often need to feed each one individually, resulting in low work efficiency. Furthermore, the high intensity of repetitive manual operations can easily lead to uneven feeding or unstable cycle times, severely restricting the efficiency improvement of intermittent fixed-length double-layer feeding structures in batch processing and automated operations. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an intermittent fixed-length double-layer feeding structure, which aims to improve the difficulty of manual membrane application. The on-site operation process involves manually placing the reagent reaction cups onto the positioning fixture, which is usually done one at a time, resulting in low efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an intermittent fixed-length double-layer feeding structure, including a fixed bracket, a rotating shaft rotatably connected inside the fixed bracket, a limiting plate one sleeved on the outer wall of the rotating shaft, a double baffle sleeved on the outer wall of the rotating shaft, a limiting plate two sleeved on the outer wall of the baffle, a locking buckle provided at one end of the rotating shaft, and a lower die feeding roller rotatably connected inside the fixed bracket.

[0007] As a further description of the above technical solution:

[0008] The fixed bracket has guide rollers symmetrically arranged and rotatably connected inside. A membrane belt guide groove is fixedly connected to one side of the fixed bracket, and a vacuum connector is fixedly connected to the top of the membrane belt guide groove.

[0009] As a further description of the above technical solution:

[0010] Each side of the membrane belt guide groove is provided with a bracket, and one side of the bracket is fixedly connected to the outer wall of the fixed bracket.

[0011] As a further description of the above technical solution:

[0012] A membrane strip sensor is fixedly connected inside the bracket.

[0013] As a further description of the above technical solution:

[0014] An electric slide rail is fixedly connected inside the fixed bracket, and a bracket two is fixedly connected to the output end of the electric slide rail.

[0015] As a further description of the above technical solution:

[0016] A clamp is fixedly connected to one side of the second bracket.

[0017] As a further description of the above technical solution:

[0018] A pneumatic push rod is fixedly connected inside the fixed bracket, and a bracket three is fixedly connected to the output end of the pneumatic push rod.

[0019] As a further description of the above technical solution:

[0020] An electric scissor is fixedly connected to the top of the bracket.

[0021] As a further description of the above technical solution:

[0022] The guide rollers are symmetrically arranged and rotatably connected inside the fixed bracket.

[0023] As a further description of the above technical solution:

[0024] The rotating shafts are symmetrically arranged and rotatably connected inside the fixed bracket.

[0025] This utility model has the following beneficial effects:

[0026] In this invention, the membrane tape is first pulled out a certain distance by the clamp, and then the distance is detected by the membrane tape sensor. The output end of the pneumatic push rod drives the bracket to extend, which in turn drives the electric scissors to cut the membrane tape. This achieves the effect of automatic batch feeding by docking with automatic processing equipment, solving the difficulty of manual membrane feeding. The on-site operation process is that the reagent reaction cup is placed on the positioning fixture manually, which is usually one material at a time and has low efficiency. This invention improves the processing efficiency of the intermittent fixed-length double-layer feeding structure. Attached Figure Description

Detailed Implementation

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] Reference Figures 1-8 This utility model provides an embodiment of an intermittent, fixed-length, double-layer feeding structure, including a fixed support 1. The fixed support 1 serves as the installation and support platform for the entire feeding device, supporting, fixing, and positioning various functional components. It is a core foundational component ensuring the overall stable operation of the device. A rotating shaft 2 is rotatably connected inside the fixed support 1. The rotating shaft 2, as a key transmission component of the feeding structure, plays a crucial role in driving the synchronous operation of various connecting parts and controlling the feeding rhythm. A limiting plate 3 is fitted onto the outer wall of the rotating shaft 2. The limiting plate 3 mainly constrains and limits the rotation range of the rotating shaft 2, enabling it to rotate precisely within a specified range during operation, avoiding excessive rotation or positional deviation, thereby improving the accuracy and stability of the feeding. A double-ended baffle 5 is further fitted onto the outer wall of the rotating shaft 2. The double-ended baffle 5, in conjunction with the feeding membrane belt, enables intermittent fixed-point blocking and release, allowing the membrane belt to be conveyed and paused according to a preset rhythm during transmission, ensuring accurate implementation of fixed-length control. To further improve operational stability, a limiting plate 4 is fitted onto the outer wall of the dual baffle 5. The limiting plate 4 further restricts the movement range of the dual baffle 5, preventing it from shifting position due to vibration or uneven force during operation, thereby enhancing the overall structural coordination. A latch 6 is provided at one end of the rotating shaft 2. The latch 6 can lock the rotating shaft 2 when needed, ensuring that the rotating shaft 2 remains stationary when the device is not working or requires adjustment. This avoids membrane conveying errors caused by unexpected rotation, further ensuring the safety of the device operation and the accuracy of material feeding.

[0039] Inside the fixed bracket 1, a lower die feeding roller 17 is rotatably connected. The lower die feeding roller 17 serves as the bearing and release component for the lower film belt, enabling continuous release of the lower film belt through rotation. It maintains the tension and stability of the lower film belt during feeding, preventing unstable feeding due to slack or slippage. To further ensure the stability of the film belt conveying, guide rollers 7 are symmetrically arranged and rotatably connected inside the fixed bracket 1. These guide rollers 7 are symmetrically distributed left and right to effectively guide the double-layer film belt, keeping it straight and aligned during operation, preventing feeding quality issues caused by path deviation, uneven tension, or wrinkle stacking. A film belt guide groove 10 is fixedly connected to one side of the fixed bracket 1. The film belt guide groove 10 serves as a device to limit the film belt's trajectory, ensuring the film belt moves smoothly along a predetermined path, thus preventing belt deviation. To enhance the stability of the guide groove, brackets 8 are provided on both sides of the membrane belt guide groove 10. One side of the bracket 8 is fixedly connected to the outer wall of the fixed bracket 1 to provide reliable fixed support for the guide groove 10, so as to prevent the guide groove from shaking or deviating during operation and to ensure the stability of the membrane belt conveying path. A vacuum connector 18 is fixedly connected to the top of the membrane belt guide groove 10. The vacuum connector 18 is used to use vacuum negative pressure to adsorb the remaining membrane belt at the end of the unloading roll when there is no tension force, so as to prevent the membrane belt from loosening and to tighten the material belt.

[0040] A membrane belt sensor 9 is fixedly connected inside the first bracket 8. The membrane belt sensor 9 can detect the operating status of the membrane belt in real time, including monitoring the tension, position, and deviation of the membrane belt, and transmit the monitoring signals to the control terminal. When the membrane belt deviates or its tension is abnormal, it can provide timely feedback, thereby ensuring the continuity and accuracy of the feeding process. An electric slide rail 11 is fixedly connected inside the fixed bracket 1. The electric slide rail 11, as a linear drive mechanism, provides stable linear reciprocating motion to cooperate with the actions of the clamping and shearing components. A second bracket 12 is fixedly connected to the output end of the electric slide rail 11. The second bracket 12, as the output bearing component of the electric slide rail 11, is responsible for installing and supporting the subsequent clamp 13. The clamp 13 is installed on one side of the second bracket 12 and can fix and position the membrane belt through mechanical clamping, ensuring that the membrane belt remains in the correct position during shearing or transmission, without deviation or loosening, thereby improving the accuracy of feeding and fixed-length shearing.

[0041] A pneumatic push rod 15 is also fixedly connected inside the fixed bracket 1. The pneumatic push rod 15 serves as another driving element, utilizing pneumatic power to achieve linear push-pull action. A bracket 3 14 is fixedly connected to the output end of the pneumatic push rod 15. The bracket 3 14 acts as the actuator of the pneumatic push rod, providing stable support and transmitting thrust. An electric shears 16 is fixedly connected to the top of the bracket 3 14. The electric shears 16 is a key actuator for achieving fixed-length cutting. Its cooperation with the clamp 13 enables precise cutting after the film belt is conveyed to the predetermined fixed-length position, ensuring consistent material length and avoiding errors caused by manual cutting or imprecise control. Through the coordinated operation of the pneumatic push rod 15, the electric slide rail 11, and the electric shears 16, the entire device can automatically pause, clamp, and cut when the film belt reaches the set length, completing one full intermittent fixed-length feeding process.

[0042] Using a fixed bracket 1 as the core platform for installation and support, combined with the combination of rotating shaft 2, limit plate one 3, double baffle 5, limit plate two 4, and locking buckle 6, precise control of the material feeding rotation transmission and stable execution of intermittent actions are achieved. The lower die feeding roller 17 and symmetrically arranged guide rollers 7 effectively ensure stable tension and straight operation of the double-layer film belt during conveying. The cooperation of film belt guide groove 10, bracket one 8, and film belt sensor 9 further enables the limitation and real-time monitoring of the film belt's running trajectory. The coordinated action of electric slide rail 11, bracket two 12, clamp 13, pneumatic push rod 15, bracket three 14, and electric shears 16 achieves automated execution of film belt clamping, positioning, and fixed-length shearing. The overall structure is clearly layered and functionally integrated, effectively solving problems such as unstable film belt conveying, large length control errors, and low manual operation efficiency in traditional material feeding methods. This significantly improves the accuracy, stability, and production efficiency of double-layer material feeding, providing a highly efficient and reliable material feeding solution for related production equipment.

[0043] Working principle: When using this intermittent fixed-length double-layer feeding structure, the film belt is first placed on the outer wall of the rotating shaft 2. The two sides of the film belt are limited by the first limiting plate 3 and the second limiting plate 4, and are installed on the rotating shaft 2 by the baffle 5. Then, the locking buckle 6 locks the second limiting plate 4 and the baffle 5. Then, the film belt is also installed in the lower die feeding roller 17. After installation, the upper and lower film belts are guided around the guide roller 7. Then, the upper and lower film belts are passed through the film belt guide groove 10 and contact the film belt sensors 9 at the front and rear ends of the film belt guide groove 10, so that the film belt sensors 9 can identify the film. The vacuum structure 18 at the top of the film belt guide groove 10 is at the end of the feeding roll. When there is no tension, the remaining film strip is adsorbed by vacuum negative pressure to prevent the film strip from loosening and to tighten the material strip. Then, when it is necessary to cut the film strip, the output end of the electric slide rail 11 drives the clamp 13 to move to the left through the bracket 2 12 to clamp the film strip. Then, the output end of the electric slide rail 11 drives the clamp 13 to move to the right through the bracket 2 12, so that the film strip is pulled out a certain distance through the clamp 13. After the distance is detected by the film strip sensor 9, the output end of the pneumatic push rod 15 drives the bracket 3 14 to extend, which in turn drives the electric scissors 16 to cut the film strip, thus achieving the effect of automatic batch feeding by docking with automatic processing equipment.
