Description

Technical Field

[0001] This invention relates to the field of conveying equipment technology, specifically to an anti-clogging spiral conveyor for salad dressing. Background Technology

[0002] Salad dressing is made from vegetable oil, egg yolks, and brewed vinegar, along with seasonings and spices. When the vegetable oil and egg yolks are thoroughly mixed, an emulsification process occurs, resulting in a delicious salad dressing.

[0003] Currently, salad dressing production and packaging typically utilizes conveyor belts. However, salad dressing production is generally a vertical process, meaning the packaged dressing is transported from top to bottom. Traditional conveyor belts require multiple alternating configurations to accommodate the vertical differences in height, resulting in significant equipment investment. Furthermore, as the packaged dressing is conveyed along the inclined conveyor belt, the packaging boxes can come into contact with the conveyor's edge, causing blockages and jamming. This is similar to a herringbone downhill path, where the long distance makes it difficult to prevent the packaging boxes from hitting the conveyor belt's sidewalls, obstructing the salad dressing. As more packaging boxes are conveyed, this blockage further clogs the delivery path, impacting the overall efficiency of the salad dressing transport. Therefore, this paper proposes an anti-clogging spiral conveyor device for salad dressing to address these issues. Summary of the Invention

[0012] Preferably, the circulation frame is further connected to an inner push frame, which has the same structure as the slide bar. The inner push frame is slidably connected inside the central column. The spiral frame is also slidably connected to an inner push plate, which is connected to the inner push frame.

[0013] Preferably, the surface of the central column is provided with an opening groove, and the inner push plate is located inside the opening groove.

[0018] (III) Beneficial Effects

[0019] Compared with the prior art, the present invention provides an anti-clogging spiral conveyor device for salad dressing, which has the following beneficial effects:

[0020] 1. The anti-clogging spiral conveyor device for this salad dressing transforms the traditional straight-type crawler conveyor into a spiral conveyor through a set conveying mechanism. Therefore, the entire equipment can realize top-down spiral conveying of salad dressing. The entire equipment occupies a small area. At the same time, the spiral conveying structure can greatly avoid the salad dressing from contacting each other and blocking each other during the conveying and transfer, thereby improving the overall packaging box conveying efficiency and convenience of the salad dressing.

[0021] 2. The anti-clogging spiral conveyor device for this salad dressing, through its anti-clogging mechanism, can push the salad dressing packaging box on the spiral conveyor to the center of the conveyor, preventing the packaging box from abutting against the side wall of the spiral frame and causing jamming. This avoids blockage of the salad dressing conveyor from the side and improves the smoothness of the salad dressing packaging box conveyor.

[0022] 3. The anti-clogging spiral conveyor of this salad dressing, through its set material sorting mechanism, can automatically classify the packaging boxes. The packaging boxes are divided into two categories according to their weight. If the packaging box is lighter, it will be conveyed to the left side. If the packaging box is heavier, the ring frame will be tilted and rotated using the lever principle, thereby moving the heavier packaging box to the right side of the base. This automatically classifies the salad dressing packaging boxes by weight and ensures consistency in the material transfer and collection process. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figures 1-7 A salad dressing anti-clogging spiral conveying device includes a fixed frame 1; a conveying mechanism 2 for vertical spiral conveying of packaged salad dressing; an anti-clogging mechanism 3 for preventing the salad dressing conveyed by the spiral from clogging; and a sorting mechanism 4 for sorting and transferring the salad dressing according to the weight of the packaging box.

[0033] In this embodiment, the conveying mechanism 2 includes a spiral frame 201, with a guide frame 202 connected to the top of the spiral frame 201. The spiral frame 201 is mounted on a fixed frame 1, and a servo motor 203 is mounted on the spiral frame 201. The output end of the servo motor 203 is connected to a drive roller, and a spiral track 204 is provided on the surface of the drive roller. A transmission roller 205 is provided inside the spiral track 204, and the drive roller is connected to the transmission roller 205 through the spiral track 204. The spiral track 204 is spirally arranged inside the spiral frame 201. The conveying mechanism 2 is mainly used to achieve efficient and stable vertical spiral conveying of packaged salad dressing. This mechanism includes a spiral frame 201, with a guide frame 202 on its top for smoothly guiding the packaged box into the conveying system. The spiral frame 201 is securely installed on the fixed frame 1 by bolts or welding to ensure the rigidity and stability of the overall structure. A servo motor 203 is mounted on the spiral frame 201, and its output end is connected to the drive roller via a coupling or reducer. A spiral track 204 is mounted on the surface of the drive roller. This track is made of wear-resistant and non-slip material, and its surface may have anti-slip textures or spacers to enhance the grip on the packaging boxes. A transmission roller 205 is installed inside the spiral track 204, which is connected to the drive roller via the track, forming a closed-loop transmission system. The spiral track 204 is arranged spirally inside the spiral frame 201, forming a continuous and smooth spiral conveying channel. This enables efficient top-to-bottom conveying of salad dressing packaging boxes within a limited space, significantly saving equipment floor space and avoiding the blockage and collision problems common in traditional straight conveying methods.

[0034] Furthermore, the spiral track 204 contains multiple rotating rollers, all rotatably connected to the screw frame 201. These rollers are spirally distributed within the spiral track 204, and the surface of the spiral track 204 is provided with multiple spacers. These rotating rollers are uniformly and stably connected to the inner support structure of the screw frame 201 via bearings or bushings. The multiple rotating rollers are evenly spaced according to the spiral path, collectively forming an effective support and guiding system for the interior of the spiral track 204, ensuring that the track maintains its predetermined spiral trajectory during operation and reducing the risk of deviation or derailment. The spiral distribution of the rotating rollers is adapted to the overall shape of the spiral track 204, enabling it to operate smoothly and with low noise under the drive of the servo motor 203, while effectively distributing the weight of the packaging box and the track itself, reducing running resistance and extending the equipment's service life. Multiple spacers are provided on the load-bearing surface of the spiral track 204. These spacers are typically made of flexible or semi-rigid materials and are fixed longitudinally or obliquely to the track surface at certain intervals, forming a series of continuous blocking structures. The main function of the spacers is to increase the friction between the conveyor belt surface and the salad dressing packaging boxes, preventing the boxes from sliding or rolling off during inclined and spiral downward conveying. At the same time, the spacers appropriately separate adjacent boxes, preventing them from squeezing, colliding, or stacking, further ensuring the orderliness and stability of the conveying process, and effectively preventing blockages from a structural design perspective.

[0035] Furthermore, a drive device is installed on the transmission roller 205, which is connected to the anti-blocking mechanism 3. The drive device includes a connecting shaft 206, one end of which is connected to the transmission roller 205, and the other end of which is connected to a swing arm 209. A swing shaft 210 is connected to the swing arm 209, and a hollow frame 207 is slidably connected to the surface of the swing shaft 210. A central rod 208 is connected to the hollow frame 207, and the central rod 208 is connected to the anti-blocking mechanism 3. The drive device converts the rotational motion of the transmission roller 205 into a specific form of mechanical action, and ultimately achieves linkage with the anti-blocking mechanism 3, providing it with continuous power input. One end of the connecting shaft 206 is coaxially fixedly connected to the end of the transmission roller 205 through a key connection or flange coupling, so that it can synchronously follow the rotational motion of the transmission roller 205. The other end of the connecting shaft 206 is connected to a swing arm 209, converting the rotational motion into the circular oscillation of the swing arm 209. A swing shaft 210 is further connected to the swing arm 209. A hollow frame 207 is fitted and slidably connected to the surface of the swing shaft 210. This sliding connection is usually achieved through a sliding sleeve or linear bearing. When the swing arm 209 swings in a circular motion, the movement trajectory of the swing shaft 210 is constrained by the hollow frame 207, thereby converting the circular swing into the reciprocating motion of the hollow frame 207 in a straight line or approximately straight line in a specific direction. A central rod 208 is fixedly connected to the hollow frame 207. The central rod 208 serves as the final link for power output, directly transmitting the obtained reciprocating linear motion to the internal actuator of the anti-blocking mechanism 3. Through such a series drive chain consisting of "rotation-swing-linear motion", the power of the main conveying system is efficiently and reliably diverted to the anti-blocking system, ensuring the synchronization and coordination between the anti-blocking action and the conveying action, thereby dynamically preventing material blockage at the source.

[0036] In addition, the anti-blocking mechanism 3 includes a central column 301, a central rod 208 slidably connected inside the central column 301, a circulation frame 303 connected to the top of the central rod 208, a slide bar 304 connected to the circulation frame 303, a groove 307 formed on the slide bar 304, a sliding pin 306 slidably connected inside the groove 307, and an outer pusher 305 slidably connected to the spiral frame 201, which is connected to the sliding pin 306. The anti-blocking mechanism 3 ensures smooth spiral conveying and prevents the salad dressing packaging box from getting stuck on the side wall of the spiral frame 201. The central column 301 serves as the guide and support foundation for the entire mechanism. The central rod 208 from the drive device slides through the internal cavity of the central column 301, thereby accurately guiding the received reciprocating linear motion into the anti-blocking mechanism. A circulation frame 303 is fixedly connected to the top of the central rod 208. The circulation frame 303 reciprocates up and down synchronously with the central rod 208. At least one slide bar 304 is hinged or fixedly connected to the circulation frame 303. Each slide bar 304 has a precision-machined inclined groove 307, the extension direction of which forms a certain angle with the axis of the central column 301. A sliding pin 306 is slidably embedded inside the inclined groove 307. Simultaneously, an outer pusher 305 is slidably mounted on the screw frame 201 via a guide rail or sliding sleeve structure, its sliding direction typically pointing towards the center of the screw conveyor channel or the direction requiring material pushing. This outer pusher 305 is fixedly connected to the sliding pin 306. When the central rod 208 drives the circulation frame 303 to move vertically, it causes the slide bars 304 to move synchronously up and down. Because the sliding pin 306 is constrained by the sliding path of the outer pusher 305, it cannot follow the slide bar 304 in a purely vertical movement; therefore, the sliding pin 306 is forced to slide relative to the slide bar 304 within the inclined groove 307. The inclination angle of the sloping groove 307 decomposes the vertical movement of the slide bar 304, thereby forcibly pushing the sliding pin 306 and causing the outer pusher 305 fixed thereto to slide along the groove. In this way, the vertical reciprocating power input by the drive device is converted into a mechanical action for lateral material pushing, thereby timely pushing away the packaging box close to the side wall of the screw frame 201 and effectively preventing blockage.

[0037] In addition, an inner pusher 308 is connected to the circulation frame 303. The inner pusher 308 has the same structure as the slide bar 304. The inner pusher 308 is slidably connected inside the central column 301. An inner pusher plate is also slidably connected to the spiral frame 201, and the inner pusher plate is connected to the inner pusher 308. An opening groove 302 is opened on the surface of the central column 301, and the inner pusher plate is located inside the opening groove 302. In addition to the slide bar 304 for external anti-blocking, the circulation frame 303 is also symmetrically or parallelly connected to the inner pusher 308. The inner pusher 308 is designed with the same structure as the slide bar 304, and it also has a precisely opened inclined groove 307, thus forming a mirrored and independent motion conversion unit. The inner pusher 308 is slidably inserted inside the central column 301, and its motion trajectory is constrained by the inner wall of the central column 301, thereby ensuring its stability during up-and-down reciprocating motion. To provide the necessary space for the lateral movement of the inner push plate, an opening slot 302 is provided on the surface of the central column 301 along its axial direction. One end of the inner push plate or the connecting rod connected to it is located inside this opening slot 302 and can freely perform lateral extension and retraction movements within the slot.

[0038] It is worth noting that multiple outer pushers 305 and inner pushers are provided, and all multiple outer pushers 305 and inner pushers are spirally arranged on the spiral frame 201. The inclined grooves 307 opened on the outer pushers 305 and inner pushers have the same angle. The outer pushers 305 and inner pushers are not set individually in the system, but exist in groups of multiple. Multiple outer pushers 305 are evenly distributed along the spiral conveying path of the spiral frame 201 through their respective sliding mechanisms; similarly, multiple inner pushers are also spirally arranged in the inner area of ​​the conveying channel in a corresponding manner. This multi-group parallel spiral array layout ensures that effective pushing points can be formed at all heights and angles throughout the spiral conveying space, achieving full coverage of anti-blocking action in three-dimensional space, without any dead angles or blind spots.

[0039] It is worth noting that the sorting and transferring mechanism 4 includes a base 401. A left slide 404 and a right slide 405 are provided on the left and right sides of the base 401. A ring frame 402 is rotatably connected to the center of the base 401. A slide plate 403 is installed inside the ring frame 402. An opening 406 is provided on the ring frame 402 above the slide plate 403. Tension springs 410 are connected to both sides of the slide plate 403. The right end of the tension spring 410 is connected to the base 401 via an adjusting component. The sorting and transferring mechanism 4 realizes the function of automatically sorting and turning salad dressing packaging boxes by weight. Its main body is a fixedly installed base 401. A left slide 404 and a right slide 405 are respectively provided on the left and right sides of the working plane of the base 401. These two slides serve as the final exit after the packaging boxes are sorted. Their structure is usually designed as chutes with guide side plates to guide packaging boxes of different weights to different collection areas. A ring frame 402 is rotatably connected to the center of the base 401 via a bearing or pivot structure. The ring frame 402 can rotate freely around its midpoint within a certain angle range and is the core of the entire dispensing mechanism 4. Inside the ring frame 402, there is a sliding plate 403, typically a smooth metal or polymer sheet, used to directly receive the packaging boxes falling from the screw conveyor. An opening 406 is located at the top of the ring frame 402, directly above the receiving surface of the sliding plate 403. This opening 406 serves as the entrance for the packaging box, allowing it to fall precisely into the center area of ​​the sliding plate 403. To achieve automatic dispensing based on weight, tension springs 410 are connected to the left and right sides or front and back sides of the sliding plate 403 via hinges or flexible connectors. The other end of these springs, the right end, is not directly fixed but is ultimately connected to the base 401 via an adjusting component. This mechanism is essentially a sophisticated lever balance system. The sliding plate 403 and the ring frame 402 together form a tiltable weighing platform. When a packaging box falls into the sliding plate 403, its weight disrupts the initial balance preset by the tension springs 410. If the weight of the packaging box is insufficient to overcome the preset tension of the tension spring 410, the slide plate 403 remains stationary or only slightly tilted under the spring tension. The packaging box will mainly rely on its own weight and the slight tilt angle of the slide plate 403 to slide out from the side closer to the left slide rail 404, thus achieving the sorting of lightweight products. If the weight of the packaging box is large enough, the torque it generates will overcome the tension of the tension spring 410, forcing the entire ring frame 402 to rotate around its central axis by an angle. This action causes the tilt direction of the slide plate 403 to change significantly towards the right slide rail 405, thereby guiding the heavier packaging box into the right slide rail and completing the sorting of heavyweight products.

[0040] It is worth mentioning that the adjusting component includes an adjusting rod 407, which is rotatably connected to the base 401. A support rod 408 is threadedly connected to the surface of the adjusting rod 407, and sliders 409 are connected to both ends of the support rod 408. The sliders 409 are slidably connected to the base 401 through T-slots. By adjusting the rod 407, its rotation can be controlled to drive the threaded support rod 408 to move laterally, thereby controlling the distance to the right end of the tension spring 410. Therefore, the tension force of the tension spring 410 on the slide plate 403 can be controlled, thereby adjusting the gravity rotation value. Moving to the left means that the initial tension of the tension spring 410 decreases, and the gravity sensing decreases. When the salad dressing is lighter, it will drive the ring frame 402 to rotate, and vice versa.

[0041] It is worth noting that the pusher 305 includes a flexible frame 3051, on which a spring piece 3052 is connected, and a sliding pin 306 is connected to the flexible frame 3051. The entire flexible frame 3051 is made of elastic plastic material, which can prevent the pusher 305 from being squeezed hard when it comes into contact with salad dressing, thus protecting the salad dressing from damage. The elastic spring piece 3052 will be squeezed and deformed when it comes into hard contact with salad dressing, thus making way.

[0042] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0043] The working principle is as follows: First, the operator packages the processed salad dressing. The packaged salad dressing is then fed from the guide frame 202 to the spiral frame 201. Next, the servo motor 203 is activated, driving the drive roller to rotate. The drive roller, in turn, drives the spiral conveyor 204 to rotate cyclically. The salad dressing on the spiral conveyor 204 is then spirally conveyed downwards until it exits from the bottom of the spiral frame 201. It then enters the slide plate 403 inside the annular frame 402 through the opening 406. When the salad dressing is heavy, the right side of the slide plate 403 experiences greater weight, causing it to press down and slightly rotate the annular frame 402 clockwise. This tilts the slide plate 403 to the right, causing the salad dressing to tilt to the right onto the right slide rail 405. To prevent subsequent material from entering the slide plate 403, the arc-shaped structure above the annular frame 402... This will block the exit position of the spiral carrier 201, so the subsequent salad dressing will not be blocked temporarily. When the rotated salad dressing slides off the slide plate 403, it will receive the reset force of the tension spring 410, which will control the ring carrier 402 to rotate counterclockwise again. The subsequent salad dressing will enter the slide plate 403 again from the opening 406. When the salad dressing is lighter, the gravity cannot control the rotation of the ring carrier 402. At this time, the salad dressing will slide out from the opening 406 on the left side with the slightly tilted slide plate 403. Because the speed of the entire spiral conveyor is relatively slow, there is no concern that the salad dressing will slide directly out of the slide plate 403 due to inertia. Instead, it will slowly fall onto the slide plate 403 and then be rotated and sorted according to gravity, avoiding the situation of empty boxes or salad dressing leakage and inconsistent weight.To prevent salad dressing from colliding with the side wall of the spiral frame 201 and causing blockage, an anti-blocking mechanism 3 is installed. When the transmission roller 205 rotates with the spiral track 204, it will synchronously drive the swing arm 209 and swing shaft 210 on the connecting shaft 206 to rotate. The swing shaft 210 rotates and slides within the hollow frame 207, which will drive the hollow frame 207 and the center rod 208 to reciprocate up and down. When the center rod 208 reciprocates, it will drive the circulation frame 303 to run synchronously. The circulation frame 303 will then drive the slide bar 304 and the inner push frame 308 to move up and down. At the same time, inclined grooves 307 are opened on the slide bar 304 and the inner push frame 308. Using the principle of pin sliding, the vertical movement is converted into lateral movement. Therefore, the sliding pin 306 will move laterally within the inclined groove 307. The sliding mechanism causes the outer pusher 305 to slide within the spiral frame 201, thereby pushing the salad dressing that is against the inner wall of the spiral frame 201 to move it to the middle position of the spiral conveyor 204, achieving smooth conveying and avoiding blockage caused by the salad dressing hitting the inner wall. This structure is set around the entire spiral frame 201 and at each layer above and below, so the salad dressing conveyed on the spiral conveyor 204 will basically not hit the wall and cause blockage. The inner pusher 308 is set with the same structure, one pushing on the outside and one pushing on the inside, thus completely avoiding blockage caused by the salad dressing hitting the wall. The two inclined grooves 307 are at the same angle because the outer slide bar 304 wants to push inward, and the inner pusher 308 wants to push outward, so as to avoid the two running relative to each other and squeezing the packaged salad dressing.
