Description

Technical Field

[0001] This utility model relates to the technical field of chemical product production and packaging equipment, specifically a leveling mechanism for bagging granular chemical products. Background Technology

[0002] In the bagging process of granular chemical products, a leveling mechanism is needed to flatten the granules inside the bag to ensure uniform filling and a regular shape, facilitating subsequent sealing, stacking, warehousing, and transportation. This mechanism is typically installed after the filling station on the bagging production line. Through mechanical transmission, it drives the leveling components to act on the packaging bag, eliminating problems such as granule accumulation and voids, improving the quality of bagged products and production efficiency. It is suitable for bagging production scenarios of various granular chemical products such as fertilizers, plastic granules, and inorganic salts.

[0003] Existing leveling mechanisms can achieve initial leveling of granules inside bags through simple mechanical structures, reducing manual leveling operations and lowering labor costs. They also improve problems such as bag bulging and incomplete sealing caused by uneven particle distribution, thus enhancing production line continuity. However, existing mechanisms are mostly fixed structures, making it inconvenient to adjust the leveling force and prone to over-compacting or incomplete leveling of granules. Therefore, we provide a leveling mechanism for bagged granular chemical products to solve these problems. Utility Model Content

[0004] 1) Technical problems to be solved

[0005] This utility model proposes a leveling mechanism for bagging granular chemical products. Through the cooperation between components such as guide rods, first elastic elements, and rotating rollers, it solves the problems of existing mechanisms being mostly fixed structures, inconvenient leveling force adjustment, and prone to over-compaction or incomplete leveling of particles.

[0006] (ii) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a flattening mechanism for bagging granular chemical products, including a conveyor, a flattening mechanism above the conveyor, the flattening mechanism including a support frame, multiple sets of equidistantly arranged first elastic elements, and multiple mounting frames, the upper surface of the support frame having multiple sets of equidistantly arranged guide holes, the inner sidewalls of the multiple sets of guide holes being slidably connected to guide rods, the bottom ends of the multiple sets of guide rods being fixedly connected to the upper surfaces of the multiple mounting frames, and rotating rollers being installed in the mounting grooves of the multiple mounting frames;

[0008] The top ends of the multiple sets of the first elastic elements are fixedly connected to the inner top wall of the support frame, and the bottom ends of the multiple sets of the first elastic elements are fixedly connected to the upper surfaces of the multiple mounting frames respectively.

[0009] Furthermore, the lower surface of the support frame is fixedly connected to the upper surface of the side guard plates of the conveyor, and multiple sets of the first elastic elements are respectively sleeved on the outside of multiple sets of guide rods.

[0010] Furthermore, the conveyor is equipped with a vibration mechanism, which includes a receiving frame. The outer surface of the receiving frame is fixedly connected to one side of the conveyor's two side guard plates that are close to each other.

[0011] Furthermore, the upper surface of the receiving frame is provided with a receiving cavity, and a plurality of uniformly arranged second elastic elements are fixedly connected to the inner bottom wall of the receiving cavity, and a vibrating plate is fixedly connected to the top of the plurality of second elastic elements.

[0012] Furthermore, the upper surface of the vibrating plate in its natural state is horizontal with the upper surface of the receiving frame, and the upper surface of the vibrating plate is in contact with the inner side of the conveyor belt.

[0013] Furthermore, a servo motor is fixedly installed on the left side wall of the receiving cavity, and a rotating rod is fixedly installed on the rotating shaft of the servo motor. The right end of the rotating rod is rotatably connected to the right side wall of the receiving cavity.

[0014] Furthermore, multiple elliptical blocks are fixedly installed on the outer surface of the rotating rod, and the annular surfaces of the multiple elliptical blocks will continuously impact the lower surface of the vibrating plate as the rotating rod rotates.

[0015] (iii) Beneficial effects:

[0016] Compared with existing technologies, the leveling mechanism for bagging granular chemical products has the following advantages:

[0017] I. The leveling mechanism for the granular chemical product bag uses a guide rod, a first elastic element, and a rotating roller in cooperation. The elastic force of the first elastic element adaptively adjusts the flattening force of the rotating roller on the packaging bag. When the particles inside the packaging bag are thick, the compression of the first elastic element increases, and the flattening force is enhanced accordingly, avoiding insufficient compaction of the particles. When the particle distribution is thin, the elastic element rebounds to reduce the pressure, preventing over-compaction that could cause the packaging bag to deform or the particles to break. This effectively solves the problem of "inconvenient adjustment of flattening force" in existing fixed structure mechanisms and adapts to the bagging requirements of different filling volumes.

[0018] II. The leveling mechanism for the bagged granular chemical product utilizes a combination of rolling compression by a flattening mechanism and bottom vibration by a vibration mechanism. The rotating rollers first mechanically compress to eliminate large-area particle accumulation, while the vibration generated by the impact of the elliptical blocks against the vibrating plate fills local gaps, creating a dual leveling effect of "compression followed by vibration." Compared to existing single flattening mechanisms, this solution effectively improves the uniformity of particles within the bag, resolving the issues of "over-compacted particles or incomplete leveling," and avoiding quality defects such as bulging and incomplete sealing caused by uneven particle distribution.

Detailed Implementation

[0026] 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.

[0027] like Figure 1-5As shown, this utility model provides a technical solution: a flattening mechanism for bagging granular chemical products, including a conveyor 1, a flattening mechanism 2 above the conveyor 1, the flattening mechanism 2 including a support frame 201, multiple sets of equidistantly arranged first elastic elements 204, and multiple mounting frames 205. The upper surface of the support frame 201 has multiple sets of equidistantly arranged guide holes 202, and guide rods 203 are slidably connected to the inner sidewalls of the multiple sets of guide holes 202. The bottom ends of the multiple sets of guide rods 203 are respectively fixedly connected to the upper surfaces of the multiple mounting frames 205. Rotating rollers 206 are installed in the mounting grooves of the multiple mounting frames 205. The top ends of the multiple sets of first elastic elements 204 are fixedly connected to the inner top wall of the support frame 201, and the bottom ends of the multiple sets of first elastic elements 204 are respectively fixedly connected to the upper surfaces of the multiple mounting frames 205. The lower surface of the support frame 201 is fixedly connected to the upper surfaces of the side guard plates of the conveyor 1. The multiple sets of first elastic elements 204 are respectively sleeved on the outside of the multiple sets of guide rods 203.

[0028] The material of the first elastic element 204 is preferably a spring, and the rotating roller 206 is a common device in the prior art. This application will not elaborate on its model or internal structure.

[0029] The conveyor belt of conveyor 1 conveys the chemical product filled with granules forward at a uniform speed. When it moves directly under the flattening mechanism 2, the guide rod 203 at the bottom of the support frame 201 in the flattening mechanism 2 slides vertically along the guide hole 202. The first elastic element 204 sleeved on its outside is further compressed under the upward squeezing force generated by the packaging bag on the rotating roller 206. Through the reverse elastic force, the rotating roller 206 is made to fit tightly against the upper surface of the packaging bag and roll with the conveyor. The elastic force of the first elastic element 204 adaptively adjusts the flattening force of the rotating roller 206 on the packaging bag. When the granules in the packaging bag are thick, the compression of the first elastic element 204 increases, and the flattening force is enhanced accordingly, avoiding insufficient compaction of the granules. When the granules are thin, the elastic element rebounds to reduce the pressure, preventing excessive compaction that could cause the packaging bag to deform or the granules to break. This effectively solves the problem of "inconvenient adjustment of flattening force" in existing fixed structure mechanisms and adapts to the bagging requirements of different filling amounts.

[0030] The conveyor 1 is equipped with a vibration mechanism 3, which includes a receiving frame 301. The outer surface of the receiving frame 301 is fixedly connected to one side of the side guard plates of the conveyor 1 that are close to each other. The upper surface of the receiving frame 301 is provided with a receiving cavity 302. The inner bottom wall of the receiving cavity 302 is fixedly connected with a plurality of evenly arranged second elastic elements 303. The top of the plurality of second elastic elements 303 is fixedly connected with a vibrating plate 304. In its natural state, the upper surface of the vibrating plate 304 is horizontal with the upper surface of the receiving frame 301. The upper surface of the vibrating plate 304 is in contact with the inner side of the conveyor belt of the conveyor 1. A servo motor 305 is fixedly installed on the left side wall of the receiving cavity 302. A rotating rod 306 is fixedly installed on the rotating shaft of the servo motor 305. The right end of the rotating rod 306 is rotatably connected to the right side wall of the receiving cavity 302. A plurality of elliptical blocks 307 are fixedly installed on the outer surface of the rotating rod 306. When the annular surface of the plurality of elliptical blocks 307 rotates with the rotating rod 306, it will continuously impact the lower surface of the vibrating plate 304.

[0031] The material of the second elastic element 303 is preferably a spring. The servo motor 305 is a common electrical device in the prior art. This application will not elaborate on its model or internal structure.

[0032] The servo motor 305 inside the housing frame 301 of the vibration mechanism 3 drives the rotating rod 306 to rotate at a constant speed. The elliptical block 307 on the outer surface of the rotating rod 306 continuously impacts the lower surface of the vibrating plate 304 supported by the second elastic element 303, causing the vibrating plate 304 to vibrate up and down and transmit the vibration to the bottom of the packaging bag via the conveyor belt, prompting the particles inside the bag to fill the gaps after flattening. Through the rolling extrusion of the flattening mechanism 2 and the bottom vibration of the vibration mechanism 3, the rotating roller 206 first eliminates the accumulation of large areas of particles through mechanical extrusion, and the vibration generated by the elliptical block 307 impacting the vibrating plate 304 fills the local gaps, forming a double flattening effect of "pressing first and then vibrating". Compared with the existing single flattening mechanism, this solution can effectively improve the uniformity of particles inside the bag, solve the problem of "over-compacted particles or incomplete flattening", and avoid quality defects such as bulging of the packaging bag and poor sealing caused by uneven particle distribution.

[0033] Working principle: The chemical product packaging bag filled with granules is conveyed forward at a constant speed by the conveyor belt of conveyor 1. When it moves directly under the flattening mechanism 2, the guide rod 203 at the bottom of the support frame 201 in the flattening mechanism 2 slides vertically along the guide hole 202. The first elastic element 204 sleeved on its outside is further compressed under the upward squeezing force generated by the packaging bag on the rotating roller 206. Through the reverse elastic force, the rotating roller 206 is made to tightly fit the upper surface of the packaging bag and roll with the conveyor, squeezing the accumulated granules in the bag to the surroundings to initially eliminate bulges and voids; at the same time... At the same time, the servo motor 305 inside the housing frame 301 of the vibration mechanism 3 drives the rotating rod 306 to rotate at a constant speed. The elliptical block 307 on the outer surface of the rotating rod 306 continuously impacts the lower surface of the vibration plate 304 supported by the second elastic element 303, causing the vibration plate 304 to vibrate up and down and transmit it to the bottom of the packaging bag through the conveyor belt, so that the particles in the bag fill the gap after flattening. Finally, the packaging bag continuously completes the double flattening process of "elastic flattening + bottom vibration" under the drive of the conveyor 1, and outputs bagged products with uniform particle distribution and regular shape.
