Abstract
Description
Technical Field
[0001] The present application relates to the technical field of hopper vehicles, and in particular to a sampling structure of a feeding device. Background Art
[0002] A wet granulation line is a pharmaceutical manufacturing process that produces uniform granules by mixing powders and binders, granulating them, drying them, and screening them. The overall process is as follows: the material first enters a mixer for uniform mixing of the powder and binder, then passes through a granulator to form wet granules. The wet granules are then transferred to a hopper cart, which transports them to a drying facility for drying. The hopper cart's upper opening is aligned with the granulator's discharge port, and its lower opening is aligned with the drying facility's feed port. This ensures that the wet granules flow smoothly from the granulator into the hopper cart and then through the cart's lower opening into the drying facility. The dried granules then pass through a granulator for size adjustment and finally pass through screening equipment to obtain the desired granule specifications.
[0003] Hopper carts play a key role in wet granulation lines, facilitating the transfer of materials between different process steps. The sidewall of the hopper cart is usually equipped with a sampling tube for sampling materials during the production process. Sampling is usually required at key production stages, such as after mixing, before drying, or after drying, to ensure the consistency and quality of the materials.
[0004] In existing hopper trucks, the sampling tube structure is generally simple. When sampling is not required, the screw cap is screwed shut to prevent contamination and material leakage. When sampling, the staff needs to bring appropriate sampling tools and then open the sampling tube. However, the screw cap needs to be placed separately each time it is unscrewed. Since the upper opening of the hopper is aligned with the discharge port of the granulator, the screw cap cannot be placed on the upper end of the hopper; the protective clothing worn by the staff when entering the pharmaceutical workshop does not have a pocket design. For hygiene reasons, the screw cap is not suitable for placement in the pocket. Therefore, the existing sampling structure is relatively cumbersome and there is still room for optimization. Utility Model Content
[0005] In order to improve the convenience of sampling from a hopper car, the present application provides a feeding equipment sampling structure.
[0006] The present application provides a feeding equipment sampling structure adopting the following technical solutions:
[0007] A sampling structure for feeding equipment comprises a transport vehicle and a hopper arranged at the upper end of the transport vehicle, the side wall of the hopper is connected to a sampling tube, the outer wall of the sampling tube is protruded with a fixed shaft, the end of the fixed shaft is rotatably connected to a sliding cover covering the open end of the sampling tube; one side of the open end of the sampling tube is fixedly connected to an L-shaped limit strip, and a slot for inserting the sliding cover is formed between the L-shaped limit strip and the end face of the sampling tube; the outer wall on the other side of the open end of the sampling tube is rotatably connected to a pressure strip that presses the sliding cover, and the end of the pressure strip abuts against the sliding cover plate surface toward one side of the sliding cover.
[0008] By adopting the above technical solution, the original threaded cover design is changed to a sliding cover. When sampling is needed, it is only necessary to first turn the pressure strip outward so that the pressure strip no longer presses against the sliding cover, and then slide the sliding cover to one side until the open end of the sampling tube is exposed to the outside, and then the sampling operation can be carried out; when the sampling is completed, the sliding cover is slid in the opposite direction to close the open end of the sampling tube, and then the pressure strip is used to re-tighten it to prevent contamination and material leakage; during the opening and closing process, the sliding cover always remains connected to the sampling tube, thereby avoiding the need to store the sliding cover and improving the convenience of sampling from the hopper car.
[0009] Optionally, a mounting ring is protruded from the outer periphery of the sliding cover, the mounting ring is sleeved with the fixed shaft, and the inner wall of the mounting ring abuts against the outer periphery of the fixed shaft.
[0010] By adopting the above technical solution, after the sliding cover is slid to expose the open end of the sampling tube, the position of the sliding cover is fixed by the friction between the mounting ring and the fixed shaft, thereby preventing the sliding cover from affecting the operation of the staff.
[0011] Optionally, at least one pair of mounting seats is convexly provided on the outer circumference of the sampling tube, and each pair of mounting seats is rotatably connected to a pressure strip, and the pressure strip includes a connected pressing portion and a rotating portion.
[0012] Optionally, the rotating portion is square, the edges of the rotating portion are smoothly rounded, the pressure strip can be bent and turned over, and the outer peripheral surface of the sampling tube limits the spontaneous turning of the pressure strip.
[0013] By adopting the above technical solution, when the pressure strip is used for locking, since the rotating part is square, the outer peripheral surface of the sampling tube will limit the spontaneous flipping of the pressure strip. When unlocking is required, it is only necessary to manually bend the outward-turning pressure strip. The rotating structure design of the pressure strip is simple, thereby reducing the probability of damage here.
[0014] Optionally, the end surface of the open end of the sampling tube and the inner side of the sliding cover are provided with matching hook strips.
[0015] By adopting the above technical solution, on the basis of the double locking of the pressure strip and the L-shaped limit strip, an additional hook strip is provided to further improve the reliability of the locking.
[0016] Optionally, a sealing strip is provided on the inner side of the sliding cover.
[0017] Optionally, an anti-slip protrusion is provided on the outer side surface of the sliding cover.
[0018] In summary, the beneficial technical effects of the present application are as follows: the present application changes the original threaded cover design into a sliding cover. When sampling is needed, it is only necessary to first turn the pressure strip outward so that the pressure strip no longer presses against the sliding cover, and then slide the sliding cover to one side until the open end of the sampling tube is exposed to the outside, and then the sampling operation can be carried out; when the sampling is completed, slide the sliding cover in the opposite direction to close the open end of the sampling tube, and then use the pressure strip to tighten it again, and the hook strip assists in limiting the sliding cover from detaching from the open end of the sampling tube. The pressure strip, L-shaped limit strip and hook strip cooperate to prevent contamination and material leakage. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following is combined with Figure 1-3 This application is described in further detail.
[0024] In this paper, a coordinate system XYZ is set, where the positive direction of the Z axis represents the top, the negative direction of the Z axis represents the bottom, the positive direction of the Y axis represents the front, the negative direction of the Y axis represents the back, the positive direction of the X axis represents the right, and the negative direction of the X axis represents the left.
[0025] The present application embodiment discloses a feeding equipment sampling structure. Figure 1 The sampling structure of the feeding device includes a transport vehicle 1 and a hopper 2 installed on the upper end of the transport vehicle 1. The main structure and working principle of the transport vehicle 1 and the hopper 2 are consistent with those of the existing hopper vehicle, and the installation method of the hopper 2 on the transport vehicle 1 is also consistent with that of the existing hopper vehicle, which will not be repeated here.
[0026] A sampling tube 3 is integrally formed on the side wall of the hopper 2. This tube 3 extends through the interior of the hopper 2 and has an open end. The tube 3 is positioned downwardly and tilted, allowing samples to be taken during production to ensure material consistency and quality.
[0027] Reference Figure 2 and Figure 3 The outer wall of the sampling tube 3 is integrally formed with a fixed shaft 31, which is rotatably connected to the sliding cover 4. The outer periphery of the sliding cover 4 is integrally formed with a mounting ring 41. The mounting ring 41 is sleeved with the fixed shaft 31, and the inner wall of the mounting ring 41 abuts the outer periphery of the fixed shaft 31, so that the end of the fixed shaft 31 is rotatably connected to the sliding cover 4.
[0028] The side of the sliding cover 4 facing the open end of the sampling tube 3 is the inner side of the sliding cover 4, while the side of the sliding cover 4 facing away from the open end of the sampling tube 3 is the outer side of the sliding cover 4. The outer surface of the sliding cover 4 is provided with anti-slip protrusions 42. When the sliding cover 4 is slid along the anti-slip protrusions 42, the friction between the mounting ring 41 and the fixed shaft 31 secures the position of the sliding cover 4. The fixed shaft 31 can be positioned at the upper or lower end of the sampling tube 3; it is only necessary to ensure that the mounting ring 41 is positioned in alignment with the fixed shaft 31. To facilitate sampling, this embodiment of the present application illustrates the fixed shaft 31 positioned at the upper end of the sampling tube 3.
[0029] An inverted L-shaped limit strip 32 is integrally formed on the right side of the open end of the sampling tube 3. A slot 33 for inserting the sliding cover 4 is formed between the horizontal plate of the L-shaped limit strip 32 and the end face of the sampling tube 3. When the sliding cover 4 slides to abut the inner wall of the L-shaped limit strip 32, the sliding cover 4 just covers the open end of the sampling tube 3.
[0030] The outer peripheral surface on the left side of the open end of the sampling tube 3 is integrally formed with at least one pair of mounting seats 34. Each pair of mounting seats 34 is rotatably connected to a pressure strip 5. The end of the pressure strip 5 away from the mounting seat 34 is used to press and lock the sliding cover 4. There can be multiple pressure strips 5. It is only necessary to keep the number of mounting seats 34 and pressure strips 5 corresponding. For the convenience of sampling, the embodiment of the present application uses one pressure strip 5 and a pair of mounting seats 34 as an example, and the pressure strip 5 is set in the middle of the left side of the sampling tube 3.
[0031] The pressure strip 5 includes an integrally formed pressing portion 51 and a rotating portion 52. In one embodiment, the rotating portion 52 is square, and the edges of the rotating portion 52 are smoothly rounded. The rotating portion 52 is rotatably connected between two adjacent mounting seats 34 via a rotating shaft. The outer peripheral surface of the sampling tube 3 will limit the spontaneous flipping of the pressure strip 5, but the smoothly rounded edges allow the pressure strip 5 to be manually flipped. In another embodiment, the rotating portion 52 is a conventional cylindrical shape, and the friction between the rotating portion 52 and the rotating shaft is used to limit the pressure strip 5. This application takes the first embodiment as an example. When the pressure strip 5 presses the sliding cover 4, the pressing portion 51 abuts against the surface of the sliding cover 4 toward the side of the sliding cover 4.
[0032] A sealing strip 6 is bonded to the inside of the sliding cover 4. Its shape matches that of the sliding cover 4. When the sliding cover 4 is closed, the sealing strip 6 presses against the end face of the sampling tube's opening, thus providing a seal. The end face of the sampling tube's opening 3 and the inside of the sliding cover 4 are integrally formed with matching hooks 61. When the two hooks 61 are engaged and secured, the sliding cover 4 securely covers the open end of the sampling tube 3.
[0033] The implementation principle of the sampling structure of a feeding device in an embodiment of the present application is: when sampling is required, first bend the outward-turned pressure strip 5 so that the pressure strip 5 no longer abuts the surface of the sliding cover 4, and then slide the sliding cover 4 from right to left by pressing the anti-slip protrusion 42, so that the open end of the sampling tube 3 is exposed to the outside, and sampling can be carried out at this time.
[0034] After the sampling is completed, the sliding cover 4 is re-closed from left to right so that the hook strip inside the sliding cover 4 is engaged with the hook strip at the open end of the sampling tube 3. At this time, the outer circumference of the sliding cover 4 abuts against the inner circumference of the L-shaped limit strip 32, and then the pressing strip 5 is turned inward to press against the plate surface of the sliding cover 4, and the open end of the sampling tube 3 is completely sealed.
[0035] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
