Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, and in particular to an automatic cleaning system for packaging machines. Background Technology

[0002] Filling machines are core equipment in pharmaceutical, food, and fine chemical industries for quantitative filling. They typically consist of a frame, filling head, and conveyor. Powder or granules in the hopper are metered by a screw, vibration, or negative pressure and then fall into the container below. The conveyor then feeds the container out in a step-by-step manner, achieving high-speed continuous packaging. To increase production capacity, modern filling machines use open conveyor belts and increase operating speed, enabling a single production line to produce thousands of bottles per hour.

[0003] High-speed operation brings residual risks. Powder easily adheres to the surface of the conveyor belt and falls off with vibration during the return section, forming dust. This not only pollutes the cleanroom but also causes cross-contamination. Manual wiping requires stopping the machine for disassembly, which is time-consuming and can easily scratch the belt surface. Existing external dust collection hoods can only collect the scattered dust and cannot eliminate the root cause of the sticky material, resulting in a high cleaning frequency and wasting a lot of time. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an automatic cleaning system for a dispensing machine.

[0005] This utility model is achieved using the following technical solution: an automatic cleaning system for a dispensing machine, comprising a frame, a dispensing machine body fixedly mounted on the top of the frame, a conveyor platform installed inside the frame, a pump fixedly mounted inside the dispensing machine body, a suction head fixedly connected to the input end of the pump, a collection box fixedly connected to the output end of the pump, a connecting frame fixedly connected to the rear end of the frame, a sliding groove formed on the inner wall of the connecting frame, a slider slidably connected inside the sliding groove, a moving plate fixedly connected to the end of the slider away from the sliding groove, a sliding rod slidably connected inside the moving plate, a scraper fixedly connected to the bottom of the sliding rod, and a spring fixedly connected to the top of the scraper.

[0006] By integrating negative pressure suction and elastic scraping into the same frame, the scraper peeling, pump suction, and collection box storage form a continuous closed loop. The conveyor belt completes one peeling-suction-seal cycle every one rotation. At the same time, the spring gives the scraper floating ability, which maintains full contact and avoids hard collisions, taking into account both cleaning efficiency and component life, thereby achieving online cleaning of the dispensing machine without dust spillage.

[0007] As a further improvement to the above solution, the conveyor platform is located below the output end of the dispensing machine body, and the pump is located above the conveyor platform.

[0008] The above technical solution places the conveyor platform directly below the output end of the dispensing machine body, and the pump is placed above the conveyor platform, so that the material drop point, the adhesion area and the suction inlet are in the same vertical channel.

[0009] As a further improvement to the above solution, two slides are provided, and the two slides are evenly distributed symmetrically around the top center of the connecting frame.

[0010] The above technical solution involves symmetrically setting double sliding grooves on the inner wall of the connecting frame to ensure that the forces at both ends of the moving plate are balanced, and that the scraper and the conveyor belt remain parallel during operation to prevent uneven wear.

[0011] As a further improvement to the above solution, the slide rod passes through the top of the moving plate, the scraper is sleeved inside the moving plate, the spring is sleeved on the surface of the slide rod, the upper and lower ends of the spring are in contact with the top of the inside of the moving plate and the top of the scraper, respectively, and the scraper material at the rear end of the scraper is made of rubber.

[0012] Through the above technical solution, the slide bar passes through the moving plate and a spring is installed inside it. The scraper is limited by the moving plate. During operation, the spring presses the scraper against the conveyor belt. When it encounters a protrusion or hard block, the spring compresses and pushes the blade away. After leaving the obstacle, it automatically resets, which maintains a constant scraping pressure and avoids rigid impact, thus protecting the belt surface and the blade.

[0013] As a further improvement to the above solution, a limit rod is fixedly connected inside the slide, and a spring is fixedly connected to the bottom of the slide.

[0014] With the above technical solution, a limiting rod is fixed in the chute and a second spring is added. When the slider rises and falls, it is guided by the limiting rod and the second spring provides bottom support. During operation, the moving plate can be adjusted up and down more smoothly. After stopping the machine, the second spring will lift the slider to the initial high position, which facilitates quick replacement or maintenance of the scraper.

[0015] As a further improvement to the above solution, the limiting rod passes through the slider, and the bottom of the spring is fixedly connected to the inner wall of the frame.

[0016] With the above technical solution, the limiting rod passes through the slider and the bottom of the second spring is fixed to the inner wall of the frame, so that the slider can only move vertically and will not sway left and right during operation, thus ensuring the parallelism between the scraper blade and the conveyor belt.

[0017] As a further improvement to the above solution, a threaded sleeve is fixedly connected to the top of the connecting frame, a threaded rod is threadedly connected inside the threaded sleeve, a throttle is fixedly connected to the top of the threaded rod, and a pressing plate is fixedly connected to the bottom of the threaded rod.

[0018] The above technical solution involves setting a threaded sleeve, a threaded rod, a throttle, and a pressing plate on the top of the connecting frame. By rotating the throttle, the threaded sleeve can drive the pressing plate to rise and fall. During operation, the height of the moving plate can be precisely adjusted, thereby fine-tuning the pressure of the scraper on the conveyor belt to adapt to conveyor belts of different thicknesses or materials.

[0019] As a further improvement to the above solution, the bottom of the threaded rod penetrates the inner wall of the connecting frame, causing the bottom of the pressing plate to contact the top of the moving plate.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model, by setting up a pump, suction head, collection box, and scraper that adheres to the surface of the conveyor, allows the scraper to peel off the adhering material in advance during the operation of the conveyor belt. The pump then simultaneously sucks the peeled material and dust into the collection box, realizing an online operation mode of cleaning while conveying. This achieves the effect of preventing dust from escaping and continuously improving the cleanliness of the production environment.

[0021] This invention, by setting up a sliding rod-spring-floating structure and a limiting rod-spring-reset structure, enables the scraper to retract upwards and automatically return to its original position when encountering firmly adhered materials. During operation, it maintains a constant contact pressure and avoids rigid impacts, thus preventing direct rigid contact with the conveyor belt on the transport platform and avoiding damage.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] Example: Please combine Figure 1-4 An automatic cleaning system for a dispensing machine according to this embodiment includes a frame 1, a dispensing machine body 2 fixedly mounted on the top of the frame 1, a conveyor table 3 installed inside the frame 1, a pump 4 fixedly mounted inside the dispensing machine body 2, a suction head 5 fixedly connected to the input end of the pump 4, a collection box 6 fixedly connected to the output end of the pump 4, a connecting frame 7 fixedly connected to the rear end of the frame 1, a sliding groove 8 opened on the inner wall of the connecting frame 7, a slider 9 slidably connected inside the sliding groove 8, a moving plate 10 fixedly connected to the end of the slider 9 away from the sliding groove 8, a sliding rod 11 slidably connected inside the moving plate 10, a scraper 12 fixedly connected to the bottom of the sliding rod 11, and a spring 13 fixedly connected to the top of the scraper 12.

[0026] During operation, the conveyor belt of the conveyor platform 3 comes into contact with the scraper of the scraper 12, causing the scraper to scrape off the material adhering to its surface and remove it from the surface of the conveyor platform 3. At the same time, the input end of the pump 4 adsorbs the scraped material and the dust attached to the surface of the conveyor belt, and transports it to the inside of the collection box 6 through the output end of the pump 4 to clean the entire dispensing machine during the dispensing process and prevent dust from spreading.

[0027] The conveyor platform 3 is located below the output end of the dispensing machine body 2, and the pump 4 is located above the conveyor platform 3. The conveyor platform 3 is arranged directly below the output end of the dispensing machine body 2, and the pump 4 is placed above the conveyor platform 3, so that the material drop point, the adhesion area and the suction inlet are in the same vertical channel.

[0028] There are two chutes 8, which are symmetrically and evenly distributed around the top center of the connecting frame 7. The double chutes 8 are symmetrically arranged on the inner wall of the connecting frame 7 so that the forces on both ends of the moving plate 10 are balanced. During operation, the scraper 12 remains parallel to the conveyor belt to prevent uneven wear.

[0029] The slide bar 11 passes through the top of the movable plate 10, the scraper 12 is sleeved inside the movable plate 10, and the spring 13 is sleeved on the surface of the slide bar 11. The upper and lower ends of the spring are in contact with the top of the interior of the movable plate 10 and the top of the scraper 12, respectively.

[0030] The slide 8 is fixedly connected to a limit rod 14, and the bottom of the slide 8 is fixedly connected to a spring 15. The limit rod 14 is fixed inside the slide 8 and the spring 15 is added. When the slider 9 rises and falls, it is guided by the limit rod 14 and the spring 15 provides bottom support. During operation, the moving plate 10 can be adjusted up and down more smoothly.

[0031] The limit rod 14 passes through the slider 9, and the bottom of the spring is fixedly connected to the inner wall of the frame 1.

[0032] A threaded sleeve 16 is fixedly connected to the top of the connecting frame 7. A threaded rod 17 is connected to the inside of the threaded sleeve 16. A handle 18 is fixedly connected to the top of the threaded rod 17. A pressing plate 19 is fixedly connected to the bottom of the threaded rod 17. By rotating the handle 18, the threaded sleeve 16 can drive the pressing plate 19 to rise and fall. During operation, the height of the moving plate 10 can be precisely adjusted, thereby fine-tuning the pressure of the scraper 12 on the conveyor belt, adapting to conveyor belts of different thicknesses or materials, and expanding the versatility of the equipment.

[0033] The bottom of the threaded rod 17 penetrates the inner wall of the connecting frame 7, causing the bottom of the pressing plate 19 to contact the top of the moving plate 10.

[0034] The implementation principle of an automatic cleaning system for a dispensing machine in this embodiment is as follows: When the dispensing machine is automatically cleaned, the sliding plate 10 is first moved by the slider 9 so that the scraper at the front end of the scraper 12 contacts the surface of the conveyor table 3. After the scraper position is adjusted, the pump 4 is started. After the dispensing machine body 2 has finished loading the material, it needs to be conveyed through the conveyor table 3, which causes the material to stick to the surface of the conveyor table 3. When the conveyor table 3 is running, the conveyor belt of the conveyor table 3 contacts the scraper of the scraper 12, so that the scraper scrapes off the material stuck to its surface and removes it from the surface of the conveyor table 3. At the same time, the input end of the pump 4 adsorbs the scraped material and the dust attached to the surface of the conveyor belt, and conveys it to the inside of the collection box 6 through the output end of the pump 4 to clean the entire dispensing machine during the dispensing process and prevent dust from spreading.

[0035] At the same time, when the scraper comes into contact with the conveyor belt of the conveyor platform 3, the scraper squeezes the conveyor belt. When it encounters a sticky object that is too firm, the scraper 12 squeezes the spring 13 to avoid the scraper making rigid contact with the conveyor belt, which could lead to damage.

[0036] Rotating the threaded rod 17 by throttle 18 causes the threaded rod 17 to rotate inside the threaded sleeve 16, which in turn causes the pressing plate 19 to press the top of the moving plate 10, and the scraper at the front end of the straight scraper 12 to contact the conveyor belt of the conveyor table 3.

[0037] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
