Description

Technical Field

[0001] This utility model belongs to the field of compound fertilizer packaging technology, specifically a speed control device for bagged compound fertilizer materials. Background Technology

[0002] Typically, after being weighed, packaged, and sealed, compound fertilizer granules need to be transported to a finished product warehouse for robotic palletizing. To facilitate this transport, the weighing, packaging, and sealing processes for compound fertilizer granules are usually located on the second floor, while the finished product warehouse is on the first floor, with a height difference of approximately 6 meters. Conventional compound fertilizer bagged material conveying uses power transmission, allowing for slow transport of the bags to avoid impacting the conveyor belts of subsequent processes. However, this method has the drawback of consuming excessive electricity. Furthermore, because the speed of the compound fertilizer bags needs to be controlled by power, this type of conveyor belt has a relatively gentle slope, resulting in a longer conveyor belt and occupying a larger area of ​​the warehouse. Due to the large area required, some companies have adopted non-powered conveyor belts to transport bagged compound fertilizer materials in order to reduce energy consumption and minimize equipment footprint (i.e., using the weight of the bagged compound fertilizer materials in conjunction with the conveyor belt for transport). To ensure smooth transport of the bagged compound fertilizer materials and minimize equipment footprint, the conveyor angle is generally set at around 30° to 35°. However, during use, the excessive speed of the bagged compound fertilizer materials can impact the conveyor belt of the next process, causing conveyor belt failure. Furthermore, the bagged materials are prone to tilting, preventing the robotic arm from stacking properly and requiring manual intervention to ensure normal stacking function. Utility Model Content

[0003] To overcome the above deficiencies, this utility model provides a speed control device for bagged compound fertilizer materials to solve the technical problems existing in the prior art.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A speed control device for bagged compound fertilizer materials includes an inclined, unpowered conveying body, which includes an inclined, unpowered conveying frame and unpowered rollers disposed inside the frame. A fixed support is provided in the lower middle part of the unpowered conveying frame, and a deceleration unit for the bagged compound fertilizer materials is mounted on the fixed support. The deceleration unit includes a bag-pressing plate disposed on the top of the unpowered rollers. The front part of the bag-pressing plate is connected to the fixed support via a rotating shaft, and the rear middle part of the bag-pressing plate is connected to the fixed support via a spring.

[0006] The beneficial effects of this utility model are as follows: This utility model, used in conjunction with a non-powered conveyor body, is mainly used to control the speed of the compound fertilizer bagged material, avoiding defects such as malfunctions caused by excessive speed impacting the conveyor belt; this utility model is preferably located in the middle and rear part of the non-powered conveyor body to decelerate the compound fertilizer bagged material from the upper part, allowing it to slowly enter the subsequent process; the key point of this utility model is that while decelerating the compound fertilizer bagged material, it allows it to smoothly pass through the bag-pressing plate and enter the rear part of the non-powered conveyor body, avoiding jamming between the bag-pressing plate and the non-powered idler rollers. To address the problem of bagged compound fertilizer materials, this utility model employs a rotatable rotating shaft at the front of the bag-pressing plate and a spring structure at the rear. When the bagged compound fertilizer material with a large impact force contacts the bag-pressing plate, it directly impacts the rear of the bag-pressing plate due to inertia. The rear of the bag-pressing plate can compress the spring and move upward under the action of the rotating shaft, causing the bagged compound fertilizer material to decelerate and pass through the bag-pressing plate. After the bagged compound fertilizer material passes through the bag-pressing plate, the spring can reset the bag-pressing plate. This achieves the characteristic of buffering the bagged compound fertilizer material without the need for manual intervention.

[0007] Preferably, the distance between the front part of the bag-pressing plate and the non-powered roller is greater than the thickness of the compound fertilizer bag material, the distance between the rear part of the bag-pressing plate and the non-powered roller is less than the thickness of the compound fertilizer bag material, and the end of the bag-pressing plate has an upwardly inclined slope structure.

[0008] Preferably, the front part, the rear part, and the end of the bag-pressing plate are an integral structure.

[0009] Preferably, the inner side of the unpowered conveying frame on the unpowered roller is provided with a baffle for adjusting the posture of the compound fertilizer bag, and a number of support rods are provided between the baffle and the unpowered conveying frame.

[0010] Preferably, the fixed bracket is a semi-enclosed structure with an open bottom. The bottom of the fixed bracket is fixedly connected to the non-powered conveying frame by bolts. Rotary shaft fixing plates are fixedly installed on the front of both side walls of the fixed bracket. Bushings are provided on the rotating shaft fixing plates. A rotating shaft is provided between the two bushings. The middle of the rotating shaft is fixedly connected to the front of the bag pressing plate.

[0011] Preferably, the spring part includes a first fixing plate connected to the rear part of the pressure bag plate and a second fixing plate connected to the upper part of the fixing bracket. A lower support shaft is installed on the first fixing plate and an upper support shaft is installed on the second fixing plate. A screw passes through the upper support shaft and is screwed to the lower support shaft. A spring seat is fitted on the screw between the upper support shaft and the lower support shaft, and a spring is fitted on the screw between the spring seat and the lower support shaft.

[0012] Preferably, a lower height adjusting nut is fitted on the screw between the spring seat and the upper support shaft, and an upper height adjusting nut is fitted on the screw at the upper part of the upper support shaft.

[0013] A speed control device for compound fertilizer bagged materials manufactured according to the above scheme is applicable to the use of compound fertilizer bagged materials when conveyed by their own gravity in conjunction with a non-powered conveyor body. Due to the need to consider the use of gravity sliding and space constraints, the material causes significant impact on the lower part of the conveyor belt and subsequent processes during the conveying process. This utility model achieves deceleration of the compound fertilizer bagged materials by setting a deceleration unit in the middle and rear part of the non-powered conveyor body. Furthermore, the bag pressing plate mentioned in this utility model is a movable structure, specifically referring to... The front part can rotate around the axis, and the rear part can move up and down. The above-mentioned movable structure can decelerate the compound fertilizer bagged material while allowing the compound fertilizer bagged material to use inertia to push open the rear of the bag pressing plate and move downward, avoiding it from getting stuck between the bag pressing plate and the non-powered roller. At the same time, this utility model also has a baffle with a support rod to adjust the posture of the compound fertilizer bagged material, so that the compound fertilizer bagged material can pass smoothly through the bag pressing plate. It has a simple structure and reasonable design, and can decelerate the material without changing the original non-powered conveying system. It not only avoids impact on subsequent equipment, but also effectively reduces labor intensity. Attached Figure Description

[0019] 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 scope of protection of the present utility model.

[0020] The following is in conjunction with the appendix Figure 1-3 This application provides a detailed description of a speed control device for bagged compound fertilizer materials. The device includes an inclined, unpowered conveying body, which comprises an inclined unpowered conveying frame 1 and unpowered rollers 2 disposed inside the frame 1. A fixed support 3 is located in the lower middle part of the frame 1, and a deceleration unit for the bagged compound fertilizer materials is mounted on the fixed support 3. The deceleration unit includes a pressure plate 4 located on top of the rollers 2. The front part of the pressure plate 4 is connected to the fixed support 3 via a rotating shaft, and the rear middle part of the pressure plate 4 is connected to the fixed support 3 via a spring. This invention is mainly applied in unpowered raw material conveying equipment. Its essence lies in using a fixed support 3 in the lower middle part of the frame 1 to achieve forward movement of the material impacting the equipment. Simultaneously, the material's inertia is utilized to decelerate the material while passing through the pressure plate 4, thereby reducing manual intervention and achieving continuous material conveying. The bag-pressing plate 4 and several unpowered rollers 2 described in this utility model can be arranged in parallel or non-parallel configurations. The distance between the rear part of the bag-pressing plate 4 and the unpowered rollers 2 is based on the thickness of the compound fertilizer packaging bag. The front part of the bag-pressing plate 4 is connected to the rotating shaft. When the rear part of the bag-pressing plate 4 is impacted, the rear part of the bag-pressing plate 4 is displaced upward and can move upward conveniently using the rotating shaft. When the bag-pressing plate 4 is reset under the action of the spring, it can move downward conveniently using the rotating shaft.

[0021] Furthermore, the distance between the front part of the bag-pressing plate 4 and the unpowered roller 2 is greater than the thickness of the compound fertilizer bag material, while the distance between the rear part of the bag-pressing plate 4 and the unpowered roller 2 is less than the thickness of the compound fertilizer bag material. The end of the bag-pressing plate 4 has an upwardly inclined slope structure. This design facilitates the smooth entry of the compound fertilizer bag between the bag-pressing plate 4 and the unpowered roller 2. Simultaneously, after the rear part of the bag-pressing plate 4 is impacted, the distance between the bag-pressing plate 4 and the unpowered roller 2 is increased, allowing the compound fertilizer bag to pass quickly after deceleration.

[0022] Furthermore, the front part, rear part, and end of the pressure plate 4 are integrally formed. As mentioned above, the pressure plate 4 in this invention withstands the impact from the material. Based on this, this invention reduces the impact force by placing the pressure plate 4 in the lower middle part of the unpowered conveying frame 1. Furthermore, the strength of the pressure plate 4 is improved by making the front part, rear part, and end of the pressure plate 4 integrally formed.

[0023] Furthermore, the inner side of the unpowered conveying frame 1 on the unpowered roller 2 is provided with a baffle 5 for adjusting the posture of the compound fertilizer bag, and a plurality of support rods 6 are provided between the baffle 5 and the unpowered conveying frame 1. In this utility model, the baffle 5 is two, respectively arranged on the two inner sides of the unpowered conveying frame 1. Preferably, as shown... Figure 1 As shown, the upper part of the baffle 5 is a sloping structure that tilts inward toward the non-powered conveying frame 1. This allows for adjustment of the posture of the compound fertilizer packaging bag from above. This adjustment primarily aims to prevent the compound fertilizer packaging bag from entering obliquely between the pressing plate 4 and the non-powered roller 2. In actual use, when the compound fertilizer packaging bag enters obliquely between the pressing plate 4 and the non-powered roller 2, the pressure on the pressing plate 4 is uneven, and the compound fertilizer packaging bag is relatively long, making it easy for the bag to be jammed by the rear of the pressing plate 4, thus affecting the continuous conveying of materials. Furthermore, this invention enhances the strength of the baffle 5 by setting several support rods 6, thereby increasing its service life and preventing problems such as deformation of the baffle 5.

[0024] Furthermore, the fixed bracket 3 is a semi-enclosed structure with an open bottom. The bottom of the fixed bracket 3 is fixedly connected to the non-powered conveying frame 1 by bolts. Rotary shaft fixing plates 7 are fixedly installed on the front of both side walls of the fixed bracket 3. Bushings 8 are provided on the rotating shaft fixing plates 7, and a rotating shaft 9 is provided between the two bushings. The middle part of the rotating shaft 9 is fixedly connected to the front part of the bag pressing plate 4. The fixed bracket 3 described in this utility model can be fixed on the ground at a position corresponding to the non-powered conveying frame 1; or fixed on the non-powered conveying frame 1. In the actual installation process, the distance between the bag pressing plate 4 and the non-powered roller 2 needs to be considered to facilitate the smooth entry of the compound fertilizer packaging bag between the bag pressing plate 4 and the non-powered roller 2, and to create an impact on the rear of the bag pressing plate 4 to slow down the speed of the compound fertilizer packaging bag.

[0025] Furthermore, the spring part includes a first fixing plate 10 connected to the rear part of the pressure bag plate 4, and a second fixing plate 11 connected to the upper part of the fixing bracket 3. A lower support shaft 12 is installed on the first fixing plate 10, and an upper support shaft 13 is installed on the second fixing plate 11. A screw 14 passes through the upper support shaft 13 and is screwed to the lower support shaft 12. A spring seat 15 is fitted on the screw 14 between the upper support shaft 13 and the lower support shaft 12, and a spring 16 is fitted on the screw 14 between the spring seat 15 and the lower support shaft 12.

[0026] Furthermore, a lower height adjusting nut 17 is fitted on the screw 14 between the spring seat 15 and the upper support shaft 13, and an upper height adjusting nut 18 is fitted on the screw 14 at the upper part of the upper support shaft 13.

[0027] The specific working process of this utility model is as follows: When using this utility model, the deceleration unit for compound fertilizer bagged materials is fixed in the lower middle part of the non-powered conveying frame 1. Preferably, the distance between the front part of the pressure plate 4 and the non-powered roller 2 is greater than the thickness of the compound fertilizer bagged material, and the distance between the rear part of the pressure plate 4 and the non-powered roller 2 is less than the thickness of the compound fertilizer bagged material. When it is firmly fixed, the compound fertilizer bagged material can be conveyed. The compound fertilizer bagged material slides from the upper part to the lower part of the non-powered conveying frame 1 under the action of gravity. The compound fertilizer bag enters between the front part of the pressure plate 4 and the non-powered roller 2. The compound fertilizer bag impacts the rear part of the pressure plate 4. After being impacted, the rear part of the pressure plate 4 moves upward (the pressure plate 4 rotates around the rotating shaft 9 during the upward movement). When the pressure plate 4 moves upward, the compound fertilizer bag... The fertilizer packaging bag continues to move downward along the non-powered conveyor frame 1. When the pressure plate 4 moves upward, the spring 16 is in a compressed state. After the compound fertilizer packaging bag passes through, the pressure plate 4 returns to its original position under the action of the spring 16. The above process can achieve continuous conveying of the compound fertilizer packaging bag without manual intervention. In actual process, in order to avoid individual compound fertilizer packaging bags getting stuck between the pressure plate 4 and the non-powered roller 2, this utility model also sets a baffle 5 for adjusting the posture of the compound fertilizer bag, thereby preventing the compound fertilizer packaging bag from entering the pressure plate 4 and the non-powered roller 2 at an angle. This utility model has the advantages of simple structure, reasonable design, continuous conveying of compound fertilizer packaging bags without manual intervention, and avoidance of excessive impact force during the conveying process, which may cause damage to the conveyor belt or subsequent equipment.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
