Description

Technical Field

[0001] This utility model relates to the field of fertilizer processing technology, specifically to a multi-stage roller pressing fertilizer bag shaping device with elastic buffer. Background Technology

[0002] In the fertilizer production process, after the fertilizer is filled into bags, the fertilizer bags need to be shaped to facilitate subsequent storage, transportation, and sales. Traditional fertilizer bag shaping methods suffer from low efficiency and inconsistent shaping quality, making it difficult to meet the needs of modern production. Moreover, during the shaping process, due to fluctuations in the filling amount of the fertilizer bags and uneven distribution of fertilizer granules within the bags, the fixed-pressure shaping method can easily damage the fertilizer bags, potentially causing them to rupture and affecting the shaping effect and quality. Utility Model Content

[0003] The purpose of this invention is to provide a multi-stage roller-pressed fertilizer bag shaping device with elastic buffer that can improve the reliability and stability of fertilizer bag shaping effect and enhance shaping efficiency.

[0004] A multi-stage roller-pressed fertilizer bag shaping device with elastic buffer includes a conveying mechanism, a bag pressing mechanism, a driving mechanism, and a transmission mechanism. A mounting frame is installed on the conveying mechanism. The bag pressing mechanism and the driving mechanism are mounted on the mounting frame. The driving mechanism is connected to the transmission mechanism. The bag pressing mechanism includes a first roller pressing assembly, a second roller pressing assembly, a first elastic support assembly, and a second elastic support assembly. The first elastic support assembly is connected to the first roller pressing assembly, and the second elastic support assembly is connected to the second roller pressing assembly. The transmission mechanism is connected to both the first and second roller pressing assemblies.

[0005] In the above scheme, the bag pressing mechanism and the drive mechanism are mounted on the mounting frame, so that the bag pressing mechanism is located below the conveying mechanism. The drive mechanism is connected to the transmission mechanism, and the transmission mechanism is connected to the first roller pressing assembly and the second roller pressing assembly. In this way, the drive mechanism can drive the transmission mechanism to move, thereby enabling the transmission mechanism to drive the first roller pressing assembly and the second roller pressing assembly to roll the fertilizer bags conveyed by the conveying mechanism, which improves the efficiency of fertilizer bag shaping. The first elastic support assembly and the second elastic support assembly not only support the first roller pressing assembly and the second roller pressing assembly, but also enable the first roller pressing assembly and the second roller pressing assembly to elastically buffer during rolling, reducing damage to the first roller pressing assembly and the fertilizer bags, and ensuring the consistency and reliability of the shaping effect.

[0006] Furthermore, the transmission mechanism includes two transmission bases, a transmission rod, a drive gear, a first driven gear, and a second driven gear. The two transmission bases are mounted on both sides of the mounting bracket. The two ends of the transmission rod pass through the two transmission bases respectively. One end of the transmission rod is connected to the drive gear, and the other end is connected to the drive mechanism. The drive gear meshes with the first driven gear and the second driven gear. The first driven gear and the second driven gear are respectively connected to the first rolling assembly and the second rolling assembly.

[0007] In the above scheme, two transmission bases are installed on both sides of the mounting frame, providing a stable support structure for the transmission rod and ensuring the stability of the transmission process. The drive mechanism drives the drive gear to rotate through the transmission rod, and the drive gear then transmits power to the first driven gear and the second driven gear simultaneously. The efficiently transmitted power drives the first roller pressing assembly and the second roller pressing assembly to rotate synchronously, improving the overall operating efficiency of the equipment.

[0008] Furthermore, the first roller pressing assembly includes a first connecting plate, a second connecting plate, and a first roller pressing member. The two ends of the first roller pressing member are rotatably connected to the first connecting plate and the second connecting plate, respectively. The first connecting plate and the second connecting plate are connected to the transmission rod, and the first roller pressing member is connected to the first driven gear.

[0009] In the above scheme, one end of the first roller is connected to the first driven gear, and both ends of the first roller are rotatably connected to the first connecting plate and the second connecting plate, respectively. When the first driven gear drives the first roller to rotate, the first connecting plate and the second connecting plate provide stable support for the rotation of the first roller. The connecting rod provides support for the first connecting plate and the second connecting plate. This design also makes the overall structure more compact.

[0010] Furthermore, the first roller pressing component includes two rotating plates and several pressure plates, with both ends of the pressure plates arranged along the circumferential side of the rotating plates and connected to the rotating plates.

[0011] In the above scheme, the fertilizer bag containing fertilizer is first conveyed to the position of the first roller pressing assembly by the conveying device for pressing and shaping. The rotating plate rotates under the drive of the first driven gear, thereby driving the pressing plate to move in a circular motion. The pressing plate can press the fertilizer into a uniform distribution inside the fertilizer bag.

[0012] Furthermore, a first connecting rod is installed at the end of the first connecting plate and the second connecting plate away from the first roller. The first elastic support assembly includes a first support rod, a first limiting block, a first elastic element, and a first connecting seat. The first connecting seat is connected to the first connecting rod. One end of the first support rod is threadedly connected to the first connecting seat. The first elastic element is sleeved on the first support rod and located between the first connecting seat and the first limiting block.

[0013] In the above scheme, a first connecting rod is installed at the end of the first connecting plate and the second connecting plate away from the first roller pressing member, providing a stable connection base for the first elastic support assembly. The first elastic member is sleeved on the first support rod and located between the first connecting seat and the first limiting block. When the first roller pressing assembly rolls the fertilizer bag, the first elastic member can play an elastic buffering role, absorbing and dispersing the impact force generated during the rolling process, reducing damage to the first roller pressing assembly and the fertilizer bag. For example, when the fertilizer distribution inside the fertilizer bag is uneven or there are foreign objects, the first elastic member can adjust the pressure of the first roller pressing assembly by compression and extension, avoiding the fertilizer bag from rupturing or the first roller pressing assembly from being damaged due to excessive pressure. Since the first support rod and the first connecting seat are connected by threads, the degree of compression of the first elastic member can be changed by rotating the first support rod, thereby adjusting the elastic force of the first elastic support assembly.

[0014] Furthermore, the first elastic support assembly also includes a connecting assembly, which includes two fixing plates and a connecting column. The connecting column is sleeved on the first support rod, and its two ends are respectively connected to the two fixing plates. The fixing plates are connected to the mounting frame.

[0015] In the above scheme, the two fixing plates in the connecting assembly are connected to the mounting frame, providing a stable installation foundation for the entire first elastic support assembly. The connecting column plays a role in positioning and constraining the first support rod, ensuring that the first elastic element can extend and retract normally along the axial direction of the first support rod during operation. This can prevent the first elastic element from bending or twisting under force, ensuring the stable performance of its elastic properties. For example, when rolling fertilizer bags of different thicknesses, the first elastic element can accurately compress and rebound according to pressure changes, providing stable elastic support for the first rolling assembly and achieving uniform rolling of the fertilizer bag.

[0016] Furthermore, the second roller pressing assembly includes a third connecting plate, a fourth connecting plate, and a second roller pressing member. The two ends of the second roller pressing member are rotatably connected to the third connecting plate and the fourth connecting plate, respectively. The third connecting plate and the fourth connecting plate are connected to the transmission rod, and the cylindrical second roller pressing member is connected to the second driven gear.

[0017] In the above scheme, the two ends of the second roller are rotatably connected to the third and fourth connecting plates, respectively. This design provides reliable support for the second roller, ensuring its stability during operation, and also allows the second roller to rotate flexibly. The second roller is connected to the second driven gear. This direct connection method can efficiently transmit the power of the transmission rod to the second roller. During the rotation, the cylindrical second roller can perform comprehensive and uniform rolling of the fertilizer bag. Its smooth cylindrical surface can avoid damaging the fertilizer bag. At the same time, it further squeezes the fertilizer bag after the first roller has rolled it, making the fertilizer evenly distributed and making the fertilizer bag's appearance flatter and its shape more regular.

[0018] Furthermore, the drive mechanism includes a mounting base, a drive component, a drive wheel, and a driven wheel. The mounting base is mounted on the mounting frame, the drive component is mounted on the mounting base, the output end of the drive component is connected to the drive wheel, and the driven wheel is connected to the end of the transmission rod away from the drive gear. A transmission belt is wound around the drive wheel and the driven wheel.

[0019] In the above scheme, the mounting base ensures that the drive component is stably mounted on the mounting bracket. The output end of the drive component is connected to the drive wheel, which can drive the drive wheel to rotate, thereby driving the transmission belt to rotate. The transmission belt drives the driven wheel to rotate, thus realizing the rotation of the transmission rod.

[0020] This utility model discloses a multi-stage roller-pressed fertilizer bag shaping device with elastic buffering, which has the beneficial effects of improving the reliability and stability of fertilizer bag shaping and increasing shaping efficiency. The bag pressing mechanism and drive mechanism are mounted on a mounting frame, with the bag pressing mechanism located below the conveying mechanism. The drive mechanism is connected to a transmission mechanism, which in turn is connected to the first and second roller pressing components. This allows the drive mechanism to drive the transmission mechanism, which in turn drives the first and second roller pressing components to roll the fertilizer bags conveyed by the conveying mechanism, improving the shaping efficiency. The first and second elastic support components, while supporting the first and second roller pressing components, also provide elastic buffering during rolling, reducing damage to the first roller pressing components and the fertilizer bags, and ensuring the consistency and reliability of the shaping effect.

Detailed Implementation

[0026] The following will describe in further detail a multi-stage roller-pressed fertilizer bag shaping device with elastic buffer, in conjunction with specific embodiments and accompanying drawings.

[0027] like Figure 1 and Figure 2 As shown in a preferred embodiment, the multi-stage roller-pressed fertilizer bag shaping device with elastic buffer of the present invention includes a conveying mechanism 1, a bag pressing mechanism 2, a driving mechanism 3, and a transmission mechanism 4. A mounting frame 5 is installed on the conveying mechanism 1. The bag pressing mechanism 2 and the driving mechanism 3 are installed on the mounting frame 5. The driving mechanism 3 is connected to the transmission mechanism 4. The bag pressing mechanism 2 includes a first roller pressing assembly 21, a second roller pressing assembly 22, a first elastic support assembly 23, and a second elastic support assembly 24. The first elastic support assembly 23 is connected to the first roller pressing assembly 21, and the second elastic support assembly 24 is connected to the second roller pressing assembly 22. The transmission mechanism 4 is connected to the first roller pressing assembly 21 and the second roller pressing assembly 22.

[0028] The bag pressing mechanism 2 and the drive mechanism 3 are mounted on the mounting frame 5, so that the bag pressing mechanism 2 is located below the conveying mechanism 1. The drive mechanism 3 is connected to the transmission mechanism 4, and the transmission mechanism 4 is connected to the first roller pressing assembly 21 and the second roller pressing assembly 22. In this way, the drive mechanism 3 can drive the transmission mechanism 4 to move, thereby causing the transmission mechanism 4 to drive the first roller pressing assembly 21 and the second roller pressing assembly 22 to roll the fertilizer bags conveyed by the conveying mechanism 1, which improves the efficiency of fertilizer bag shaping. The first elastic support assembly 23 and the second elastic support assembly 24 support the first roller pressing assembly 21 and the second roller pressing assembly 22, while also enabling the first roller pressing assembly 21 and the second roller pressing assembly 22 to elastically buffer during rolling, reducing damage to the first roller pressing assembly 21 and the fertilizer bags, and ensuring the consistency and reliability of the shaping effect.

[0029] In the above embodiments, the conveying mechanism 1 is a standard belt conveyor line, which will not be described in detail.

[0030] like Figure 2 and Figure 3 As shown, in some embodiments, the transmission mechanism 4 includes two transmission bases 41, a transmission rod 42, a drive gear 43, a first driven gear 44, and a second driven gear 45. The two transmission bases 41 are mounted on both sides of the mounting frame 5. The two ends of the transmission rod 42 pass through the two transmission bases 41 respectively. One end of the transmission rod 42 is connected to the drive gear 43, and the other end is connected to the drive mechanism 3. The drive gear 43 meshes with the first driven gear 44 and the second driven gear 45. The first driven gear 44 and the second driven gear 45 are respectively connected to the first roller pressing assembly 21 and the second roller pressing assembly 22. The two transmission bases 41 are mounted on both sides of the mounting frame 5, providing a stable support structure for the transmission rod 42 and ensuring the stability of the transmission process. The drive mechanism 3 drives the drive gear 43 to rotate through the transmission rod 42. The drive gear 43 then transmits power to the first driven gear 44 and the second driven gear 45 simultaneously. The efficiently transmitted power drives the first roller pressing assembly 21 and the second roller pressing assembly 22 to rotate synchronously, improving the overall operating efficiency of the equipment.

[0031] like Figure 2 and Figure 3As shown, in some embodiments, the first roller pressing assembly 21 includes a first connecting plate 211, a second connecting plate 212, and a first roller pressing member 213. Both ends of the first roller pressing member 213 are rotatably connected to the first connecting plate 211 and the second connecting plate 212, respectively. The first connecting plate 211 and the second connecting plate 212 are connected to the transmission rod 42, and the first roller pressing member 213 is connected to the first driven gear 44. One end of the first roller pressing member 213 is connected to the first driven gear 44, and both ends of the first roller pressing member 213 are rotatably connected to the first connecting plate 211 and the second connecting plate 212, respectively. When the first driven gear 44 drives the first roller pressing member 213 to rotate, the first connecting plate 211 and the second connecting plate 212 provide stable support for the rotation of the first roller pressing member 213. The connecting rod provides support for the first connecting plate 211 and the second connecting plate 212. This design also makes the overall structure more compact.

[0032] like Figure 2 and Figure 3 As shown, in some embodiments, the first roller pressing component 213 includes two rotating plates 2131 and several pressing plates 2132. The two ends of the pressing plates 2132 are arranged along the circumferential side of the rotating plates 2131 and connected to the rotating plates 2131. The fertilizer bag containing fertilizer is first conveyed to the position of the first roller pressing component 21 by a conveying device for bag pressing and shaping. The rotating plates 2131 rotate under the drive of the first driven gear 44, thereby driving the pressing plates 2132 to move in a circular motion. The pressing plates 2132 can press the fertilizer to be evenly distributed in the fertilizer bag.

[0033] like Figure 2 and Figure 3 As shown, in some embodiments, a first connecting rod 214 is installed at one end of the first connecting plate 211 and the second connecting plate 212 away from the first roller pressing member 213. The first elastic support assembly 23 includes a first support rod 231, a first limiting block 232, a first elastic member 233 and a first connecting seat 234. The first connecting seat 234 is connected to the first connecting rod 214. One end of the first support rod 231 is threadedly connected to the first connecting seat 234. The first elastic member 233 is sleeved on the first support rod 231 and located between the first connecting seat 234 and the first limiting block 232.

[0034] The first connecting plate 211 and the second connecting plate 212 are mounted with a first connecting rod 214 at their ends away from the first roller pressing component 213, providing a stable connection base for the first elastic support assembly 23. The first elastic component 233 is sleeved on the first support rod 231 and located between the first connecting seat 234 and the first limiting block 232. When the first roller pressing assembly 21 rolls the fertilizer bag, the first elastic component 233 can act as an elastic buffer, absorbing and dispersing the impact force generated during the rolling process, reducing damage to the first roller pressing assembly 21 and the fertilizer bag. For example, when the fertilizer distribution inside the fertilizer bag is uneven or there are foreign objects, the first elastic component 233 can adjust the pressure of the first roller pressing assembly 21 by compression and extension, avoiding the fertilizer bag from rupturing or the first roller pressing assembly 21 from being damaged due to excessive pressure. Since the first support rod 231 and the first connecting seat 234 are connected by threads, the degree of compression of the first elastic component 233 can be changed by rotating the first support rod 231, thereby adjusting the elastic force of the first elastic support assembly 23.

[0035] like Figure 3 and Figure 4 As shown, in some embodiments, the first elastic support assembly 23 further includes a connecting assembly 235. The connecting assembly 235 includes two fixing plates 2351 and a connecting column 2352. The connecting column 2352 is sleeved on the first support rod 231, and its two ends are respectively connected to the two fixing plates 2351. The fixing plates 2351 are connected to the mounting frame 5. The connection of the two fixing plates 2351 in the connecting assembly 235 to the mounting frame 5 provides a stable installation foundation for the entire first elastic support assembly 23. The connecting column 2352 plays a role in positioning and constraining the first support rod 231, ensuring that the first elastic element 233 can normally expand and contract along the axial direction of the first support rod 231 during operation. This can prevent the first elastic element 233 from bending or twisting under force, ensuring the stable performance of its elastic properties. For example, when rolling fertilizer bags of different thicknesses, the first elastic element 233 can accurately compress and rebound according to the pressure change, providing stable elastic support for the first rolling assembly 21 and achieving uniform rolling of the fertilizer bag.

[0036] Reference Figure 1 The second elastic support component 24 has the same structure and principle as the first elastic support component 23, and will not be described in detail here.

[0037] like Figure 2 and Figure 3As shown, in some embodiments, the second roller pressing assembly 22 includes a third connecting plate 221, a fourth connecting plate 222, and a second roller pressing member 223. The two ends of the second roller pressing member 223 are rotatably connected to the third connecting plate 221 and the fourth connecting plate 222, respectively. The third connecting plate 221 and the fourth connecting plate 222 are connected to the transmission rod 42. The cylindrical second roller pressing member 223 is connected to the second driven gear 45. The second roller 223 is rotatably connected to the third connecting plate 221 and the fourth connecting plate 222 at both ends. This design provides reliable support for the second roller 223, ensuring its stability during operation, while also allowing the second roller 223 to rotate flexibly. The second roller 223 is connected to the second driven gear 45. This direct connection method can efficiently transmit the power of the transmission rod 42 to the second roller 223. During rotation, the cylindrical second roller 223 can perform comprehensive and uniform roller pressing on the fertilizer bag. Its smooth cylindrical surface can avoid damaging the fertilizer bag. At the same time, it further squeezes the fertilizer bag after being pressed by the first roller 213, making the fertilizer evenly distributed and making the fertilizer bag's appearance flatter and its shape more regular.

[0038] like Figure 2 and Figure 3 As shown, in some embodiments, the drive mechanism 3 includes a mounting base 31, a drive member 32, a drive wheel, and a driven wheel. The mounting base 31 is mounted on the mounting frame 5, and the drive member 32 is mounted on the mounting base 31. The output end of the drive member 32 is connected to the drive wheel, and the driven wheel is connected to the end of the transmission rod 42 away from the drive gear 43. A transmission belt is wound around the drive wheel and the driven wheel. The mounting base 31 ensures that the drive member 32 is stably mounted on the mounting frame 5. The output end of the drive member 32 is connected to the drive wheel, which can drive the drive wheel to rotate, thereby driving the transmission belt to rotate. The transmission belt drives the driven wheel to rotate, thus realizing the rotation of the transmission rod 42.

[0039] This utility model discloses the working principle and process of a multi-stage roller-pressed fertilizer bag shaping device with elastic buffer. The conveying mechanism 1 first conveys the fertilizer bag containing fertilizer to the position of the first roller pressing assembly 21 for bag pressing and shaping. The rotating plate 2131 rotates under the drive of the first driven gear 44, thereby driving the pressing plate 2132 to move in a circular motion. The pressing plate 2132 can press the fertilizer to be evenly distributed in the fertilizer bag. Then, it is conveyed to the position of the second roller pressing assembly 22 for shaping. The cylindrical second roller pressing component 223 can perform comprehensive and uniform roller pressing on the fertilizer bag during rotation, making the appearance of the fertilizer bag flatter and the shape more regular. The first elastic support assembly 23 and the second elastic support assembly 24 support the first roller pressing assembly 21 and the second roller pressing assembly 22, while also enabling the first roller pressing assembly 21 and the second roller pressing assembly 22 to elastically buffer during roller pressing, reducing damage to the first roller pressing assembly 21 and the fertilizer bag.
