Abstract

This invention discloses a fabric spreading system and method. The fabric spreading system includes a forming machine, a dryer, and a fabric spreading device. The fabric spreading device includes a driving component with an output end; a fabric spreading plate positioned above the drying belt; and a transmission assembly including a turntable and a connecting rod assembly eccentrically mounted on the turntable. The turntable is connected to the output end, and the connecting rod assembly is connected to the fabric spreading plate. The transmission assembly is configured to drive the fabric spreading plate to reciprocate along its length direction via the forward and reverse rotation of the driving component. The connecting rod assembly is detachably connected to the turntable. The transmission assembly of the fabric spreading device is a sinusoidal mechanism, and the reciprocating stroke is twice the distance from the center of the turntable to the connection point between the connecting rod assembly and the turntable. Because the connecting rod assembly is detachably connected to the turntable, when the fabric spreading device is installed on different dryers, only the position of the connection point of the connecting rod assembly on the turntable needs to be adjusted to change the reciprocating stroke of the fabric spreading plate.

Description

Technical Field

[0001] This invention relates to the field of material transportation technology, and more specifically to a material distribution system and method. Background Technology

[0002] In the production of catalysts for use in the petrochemical industry, the distributor is used to distribute the shaped catalyst material to the dryer for drying. The ideal distribution effect should ensure that the catalyst material is evenly distributed along the dryer body in terms of particle size variation, chemical composition, and moisture content, so as to ensure that the catalyst material has uniform air permeability, while ensuring that the material surface is flat and has a certain degree of looseness to prevent accumulation or pressing.

[0003] The typical catalyst feeding is mainly accomplished by the drying belt on the dryer frame. However, because the width of the discharge port of the molding machine does not match the width of the feed port of the dryer, the catalyst often accumulates in the center of the drying belt when the catalyst is fed, which is not conducive to the drying of the catalyst.

[0004] To address this, existing technologies further install specialized distributors at the outlet width of the molding machine and the inlet of the dryer to spread the catalyst on the drying belt. For example, CN220906570U discloses a distributor device and material conveying system. The distributor device includes a distributor plate and a connecting rod assembly, which is configured to drive the distributor plate to reciprocate along its length via the forward and reverse rotation of the drive shaft. However, this distributor device still has some shortcomings: the connecting rod assembly is an offset crank-slider mechanism, which, due to its quick-return characteristic, cannot guarantee the uniform spreading of the catalyst during the reciprocating motion of the distributor plate; different models of dryers have drying belts of different widths, and the width of the drying belt determines the distributor plate's stroke. Adjusting the distributor plate's stroke requires corresponding adjustments to the arm length and offset distance of the connecting rod mechanism, which is very inconvenient; the distributor plate cannot guarantee the looseness and permeability of the catalyst during distribution. Summary of the Invention

[0005] The main technical problem solved by this invention is that existing fabric feeders cannot be applied to drying belts of different widths.

[0006] To achieve the above objectives, a first aspect of the present invention provides a material distribution system, comprising: A molding machine, wherein a material hopper is provided at the bottom of the discharge port of the molding machine; A dryer includes a rotating drying belt, the feed end of which is located below the discharge end of the hopper; A spreader is used to spread the material that falls onto the drying belt; The fabric feeder includes a drive unit having an output end; a fabric plate for being positioned above the drying belt; and a transmission assembly including a turntable and a connecting rod assembly eccentrically mounted on the turntable, the turntable being connected to the output end and the connecting rod assembly being connected to the fabric plate. The transmission assembly is configured to drive the fabric plate to reciprocate along the length of the fabric plate through the forward and reverse rotation of the drive component, and the linkage assembly is detachably connected to the turntable.

[0007] In some embodiments, the transmission assembly further includes a slider and a guide rod, the slider being detachably disposed on the surface of the turntable, the guide rod being integrally disposed with the connecting rod assembly, and the guide rod having a guide groove along its length to accommodate the slider sliding within the guide rod.

[0008] In some embodiments, the length of the guide groove is greater than or equal to the diameter of the turntable.

[0009] In some embodiments, the linkage assembly includes a first linkage and a second linkage, the first linkage and the second linkage being respectively disposed on both sides of the guide rod, and the fabric plate being disposed at the lower end of the guide rod.

[0010] In some embodiments, the turntable is a ring, and the driving member is coaxially arranged with the turntable.

[0011] In some embodiments, the end face of the fabric plate is provided with a comb-like structure.

[0012] In some embodiments, a guide assembly is also included, under the action of the guide assembly, which moves along the length of the fabric plate.

[0013] In some embodiments, a limiting component is also included to limit the range of movement of the fabric plate.

[0014] In some embodiments, the limiting assembly includes two limiting blocks for mounting on the dryer, the two limiting blocks being respectively positioned on the outer side of the end of the fabric plate.

[0015] A second aspect of the present invention provides a material distribution method, wherein the distribution method is performed using the above-described distribution system.

[0016] The above technical solution provides a transmission component for the material distributor, comprising a turntable and an eccentrically positioned connecting rod assembly. Since the connecting rod assembly is connected to the material distribution plate, the rotation of the turntable can be converted into the reciprocating motion of the connecting rod assembly along the length of the material distribution plate. This structure is a sinusoidal mechanism, and the stroke of the reciprocating motion is twice the distance from the center of the turntable to the connection point between the connecting rod assembly and the turntable. Furthermore, because the connecting rod assembly and the turntable are detachably connected, when the material distributor is installed on different dryers, only the position of the connection point of the connecting rod assembly on the turntable needs to be adjusted to change the stroke of the reciprocating motion of the material distribution plate. Moreover, the transmission component of this solution has no quick-return characteristic, ensuring that the catalyst is evenly spread during the reciprocating motion of the material distribution plate.

[0025] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0026] To address the problem that existing material feeders cannot be applied to drying belts of different widths, the first aspect of this invention provides a material feeding system, comprising: The molding machine has a material hopper 2 at the bottom of its discharge port; The dryer 8 includes a rotating drying belt 1, with the feed end of the drying belt 1 located below the discharge end of the hopper 2; A material spreader is used to spread the material falling onto the drying belt 1. The material feeder includes a drive unit 6 with an output end; a material feed plate 7, which is used to be positioned above the drying belt 1; and a transmission assembly 3, which includes a turntable 31 and a connecting rod assembly 34 eccentrically positioned on the turntable 31. The turntable 31 is connected to the output end, and the connecting rod assembly 34 is connected to the material feed plate 7. The transmission assembly 3 is configured to drive the fabric plate 7 to reciprocate along the length direction of the fabric plate 7 through the forward and reverse rotation of the drive component 6, and the connecting rod assembly 34 is detachably connected to the turntable 31.

[0027] like Figure 1-3 As shown, the material discharged from the molding machine passes under the hopper 2 and falls onto the drying belt 1. The dryer 8 has its own motor that drives the drying belt 1 to rotate, so as to realize the material conveying.

[0028] The material spreader is located between the discharge end of the hopper 2 and the feed end of the drying belt 1, and preferably above the middle position of the drying belt 1. It is used to spread the material falling onto the drying belt 1. That is, when the material passes through the gap between the material spreading plate 7 and the drying belt 1, the material is spread by the obstruction of the material spreading plate 7, and the material is evenly spread on the drying belt 1 by the reciprocating motion of the material spreading plate 7.

[0029] The driving component 6 can be a motor, with its output end being the motor's output shaft. The spreading plate 7 can be a strip-shaped long plate structure, extending along the width direction of the drying belt 1. The length of the spreading plate 7 can be less than the width of the drying belt 1 to prevent the material from being spread out of the drying belt 1 during reciprocating motion. The spreading plate 7 is designed to maintain a preset distance from the drying belt 1 based on the material feeding amount. This prevents material from clogging between the spreading plate 7 and the drying belt 1, and also allows the spreading plate 1 to spread the material evenly to meet the material laying requirements.

[0030] The motion transmission between the driving component 6 and the fabric plate 7 is achieved through the transmission assembly 3. The transmission assembly 3 includes a turntable 31 and a connecting rod assembly 34. The turntable 31 is connected to the output end of the driving component 6 as the driving component, and the connecting rod assembly 34 is connected to the fabric plate 7 as the driven component.

[0031] Specifically, the transmission assembly 3 of the material distributor includes a turntable 31 and a connecting rod assembly 34 eccentrically mounted on the turntable 31. This converts the rotation of the turntable 31 into the reciprocating motion of the connecting rod assembly 34 along the length of the material distribution plate 7. This structure is a sinusoidal mechanism, and the stroke of the reciprocating motion is twice the distance from the center of the turntable 31 to the connection point between the connecting rod assembly 34 and the turntable 31. Since the connecting rod assembly 34 is detachably connected to the turntable 31, when the material distributor is installed on different dryers 8, only the position of the connection point of the connecting rod assembly 34 on the turntable 31 needs to be adjusted to change the stroke of the reciprocating motion of the material distribution plate 7. Furthermore, the transmission assembly 3 of this design has no quick-return characteristic, ensuring that the catalyst is evenly spread during the reciprocating motion of the material distribution plate 7.

[0032] In addition, the transmission assembly 3 and drive unit 6 of the material feeder should be set away from the discharge port of the hopper 2 to avoid affecting the normal conveying of materials.

[0033] In some embodiments, the transmission assembly 3 further includes a slider 32 and a guide rod 33. The slider 32 is detachably disposed on the surface of the turntable 31, and the guide rod 33 is integrally disposed with the connecting rod assembly 34. A guide groove is provided in the guide rod 33 along the length direction to accommodate the slider 32 sliding in the guide rod 33.

[0034] like Figure 1 As shown, the slider 32 can be a circular or square block, and the guide groove in the guide rod 33 can be a long strip. The guide groove and the slider 32 can be configured with a clearance fit to ensure that the slider 32 can move freely while reducing friction and wear, thereby ensuring smooth movement and mechanical durability. A guide rail can also be further provided in the guide groove to make the connection between the slider 32 and the guide rod 33 more stable when sliding.

[0035] The turntable 31 is connected to the linkage assembly 34 via a slider 32 and a guide rod 33. The linkage assembly 34 can be parallel to the length direction of the fabric plate 7, and the guide rod 33 can be perpendicular to the length direction of the fabric plate 7. Thus, when the turntable 31 rotates, the slider 32 rotates around its center with the turntable 31, enabling the linkage assembly 34, as the driven member, to reciprocate. Due to the limiting effect of the guide groove in the guide rod 33, the slider 32 simultaneously moves in the length direction perpendicular to the fabric plate 7, thereby converting the rotation of the turntable 31 into the linear motion of the slider 32, and further enabling the linkage assembly 34, which is perpendicular to the guide rod 33, to move along its length direction.

[0036] In some embodiments, the length of the guide groove is greater than or equal to the diameter of the turntable 31.

[0037] like Figure 1As shown, the reciprocating stroke of slider 32 in the guide groove of guide rod 33 is twice the distance between slider 32 and the center of turntable 31. Since slider 32 is detachably mounted on the surface of turntable 31, theoretically, the maximum distance between slider 32 and the center of turntable 31 can be the radius of turntable 31, and the length of the guide groove can be correspondingly set to the diameter of turntable 31. Preferably, the length of the guide groove can be set to be greater than the diameter of turntable 31, thus avoiding the end of guide rod 33 exerting a force on slider 32 that could affect its movement.

[0038] In some embodiments, the linkage assembly 34 includes a first linkage and a second linkage, which are respectively disposed on both sides of the guide rod 33, and the fabric plate 7 is disposed at the lower end of the guide rod 33.

[0039] like Figure 1 As shown, the connecting rod assembly 34, guide rod 33, and fabric plate 7 can form a whole. The fabric plate 7 can be directly connected to the lower end of the guide rod 33, or the fabric plate 7 and the connecting rod assembly 34 can be connected through the guide rod 33. In some other embodiments, the fabric plate 7 can also be spaced apart from the lower end of the guide rod 33. In this case, additional connectors can be provided at both ends of the fabric plate 7 to connect to the first connecting rod and the second connecting rod respectively, which can also realize the connection between the fabric plate 7 and the connecting rod assembly 34.

[0040] To further ensure uniform material distribution on the spreading plate 7, the distances from both ends of the spreading plate 7 to the guide rod 33 are set to be equal, meaning the midpoint of the spreading plate 7 is located at the lower end of the guide rod 33 or its extension. This allows the connecting rod assembly 34 to evenly spread the material across the entire surface of the drying belt 1 during reciprocating motion. The lengths of the first and second connecting rods are also set to be equal accordingly.

[0041] In some embodiments, the turntable 31 is a ring, and the drive unit 6 is coaxially arranged with the turntable 31.

[0042] like Figure 1 As shown, the turntable 31 can have a through hole in its center to form a ring. The diameter of the through hole can be equal to the diameter of the output end of the drive component 6. This allows the turntable 31 to be fitted onto the output end of the drive component 6, achieving a direct connection between the drive component 6 and the turntable 31. The drive component 6 and the turntable 31 are coaxially arranged, allowing the forward and reverse rotation of the drive component 6 to be directly transmitted to the turntable 31, achieving synchronous rotation between the drive component 6 and the turntable 31 and reducing errors in the transmission assembly 3.

[0043] In some embodiments, the end face of the fabric plate 7 is provided with a comb-like structure. For example... Figure 1 As shown, the end face of the fabric plate 7 is provided with a downwardly extending comb structure, which can increase the gap between materials and further improve the looseness and air permeability of the materials. The comb structure is preferably evenly spaced on the end face of the fabric plate 7.

[0044] In some embodiments, a guide assembly 5 is also included, and the linkage assembly 34 moves along the length of the fabric plate 7 under the action of the guide assembly 5.

[0045] like Figure 2-3 As shown, the guide component 5 guides the movement of the linkage assembly 34, so that the fabric plate 7 connected to the linkage assembly 34 can move along its own length direction, ensuring the laying effect of the material.

[0046] Specifically, the guide assembly 5 may include two support frames, and both ends of the connecting rod assembly 34 can be supported above the drying belt 1 by the support frames. One end of the support frame is detachably connected to the dryer 8, facilitating the assembly and disassembly of the support frame so that it can be used on different dryers 8. The portion of the support frame extending above the drying belt 1 can be provided with a trough, and both ends of the connecting rod assembly 34 slide in engagement with the trough, allowing the connecting rod assembly 34 to move along the length of the fabric plate 7. The support frame can be further configured to be height-adjustable to adjust the distance between the fabric plate 7 and the drying belt 1.

[0047] In some embodiments, a limiting component 4 is also included, which is used to limit the range of movement of the fabric plate 7.

[0048] like Figure 2 As shown, the limiting component 4 can prevent the material from being pulled away from the edge of the drying belt 1 due to excessive travel of the cloth plate 7. The limiting component 4 does not come into contact with the cloth plate 7 during use and mainly plays a protective role.

[0049] In some embodiments, the limiting component 4 includes two limiting blocks 41 for mounting on the dryer 8, the two limiting blocks 41 being respectively mounted on the outer side of the end of the fabric plate 7.

[0050] like Figure 2 As shown, two limiting blocks 41 are respectively set on the outer side of the end of the material distribution plate 7, and the positions of the two limiting blocks 41 can be designed according to actual needs to avoid excessive travel of the material distribution plate 7. When the material distribution plate 7 contacts the limiting block 41, the drive component 6 stops rotating to prevent the material from falling off the drying belt 1.

[0051] Specifically, the two limiting blocks 41 can be supported on the outer side of the end of the fabric plate 7 by a bracket. One end of the bracket is detachably connected to the dryer 8, facilitating the assembly and disassembly of the bracket so that it can be used on different dryers 8, saving material costs. Furthermore, the position of the limiting blocks 41 on the bracket is adjustable. For example, an elongated hole can be provided on the bracket, with the extension direction of the elongated hole consistent with the extension direction of the fabric plate 7. The limiting blocks 41 are fixed to the elongated hole by bolts. The limiting blocks 41 can be moved along the length of the elongated hole to fix them in different positions within the elongated hole, making adjustment convenient.

[0052] A second aspect of the present invention provides a method for fabric application, which is accomplished using the aforementioned fabric application system.

[0053] When in use, the material enters the hopper 2 from the outlet of the molding machine. The material in the hopper 7 will fall onto the top of the drying belt 1 due to gravity. The drive component 6 rotates to drive the material distribution plate 7 to move back and forth within a specified range through the transmission component 3 to comb the material so that the material is evenly distributed on the drying belt 1.
