Description

Technical Field

[0001] This utility model relates to a fully automatic palletizing and conveying device for functional fertilizers, belonging to the field of palletizing and conveying technology. Background Technology

[0002] Functional fertilizers are typically transported and palletized in bags during production, packaging, and warehousing. To improve fertilizer handling efficiency and reduce manual labor intensity, automated conveying and palletizing equipment is commonly installed on production lines. In such equipment, bagged fertilizers are usually transported from a lower-level conveyor line to the palletizing station, requiring the bags to remain stable and centered during transport so that robotic arms or palletizing mechanisms can accurately grasp them. The conveying device is a crucial component of automated fertilizer palletizing systems.

[0003] Existing fertilizer conveying systems mostly use belt conveyors, which use drive rollers to lift bagged fertilizer from the lower conveyor line to the higher palletizing device. In existing conveying equipment, fertilizer bags are prone to shifting during transport, and the ability to correct this shift is insufficient, affecting the alignment accuracy of subsequent palletizing. Some side baffles directly rub against the fertilizer bags, especially when the bag outer wall is rough or contains particles, easily causing wear or surface damage, affecting packaging quality. Existing adjustment devices generally have a simple structure, and some conveyor belt tensioning mechanisms lack precision or have unreliable locking methods, easily leading to problems such as conveyor belt loosening and deviation after long-term operation. The support angle of existing equipment is usually fixed, unable to be flexibly adjusted according to different workstation heights or logistics line layouts, resulting in insufficient adaptability.

[0004] Therefore, it is necessary to design a fully automated palletizing and conveying device for functional fertilizers to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a fully automatic functional fertilizer palletizing and conveying device, which solves the problems of fertilizer bags being easily misaligned, damaged, loosened after long-term transportation, and unable to be adjusted in height.

[0010] The support structure is tiltable and is equipped with a guide mechanism to keep the fertilizer being transported centered in the conveying direction; the tilt angle of the support is adjustable.

[0011] The conveying device is used to lift fertilizer from the bottom of the support to the top of the support. The conveying device includes a drive shaft, a driven shaft, and a conveyor belt. The conveyor belt is arranged around the drive shaft and the driven shaft. The drive shaft and the driven shaft are respectively arranged on the support. The drive shaft is driven to rotate by the power device.

[0012] The power unit includes a power motor and a reduction mechanism. The reduction mechanism is connected to the drive shaft. The power motor is used to drive the reduction mechanism, which in turn drives the drive shaft to rotate the conveyor belt, thereby realizing fertilizer transportation.

[0013] Preferably, the guiding mechanism includes guide plates, which are symmetrically arranged on both sides from the middle to the top of the bracket. The distance between the two guide plates gradually narrows from the bottom to the top. The fertilizer is restricted by the guide plates during movement, thus centering the fertilizer.

[0014] Preferably, the bracket is provided with a protective cover, the guide mechanism is provided on the top side of the protective cover, and the guide mechanism is provided with rollers on its side.

[0015] Preferably, an adjustment device is provided at the bottom of the driven shaft, which changes the position of the driven shaft on the bracket and changes the tension of the conveyor belt.

The fixed plate is disposed on the side of the bracket. The adjusting block is connected to the driven shaft. Controlling the adjusting bolt can change the distance between the adjusting block and the fixed plate.

[0017] Preferably, a support foot can be provided at the bottom of one side of the bracket, and the height of the support foot can be adjusted so that the tilt angle of the bracket can be adjusted by changing the height of the support foot.

[0018] The beneficial effects of this utility model are:

[0019] (1) By using this utility model, a guide plate that is symmetrical from left to right and gradually narrows from bottom to top is set on the top side of the support or the inside of the protective cover, so as to realize the effect of the bagged fertilizer shifting towards the center line step by step and being passively corrected during the rising process, thereby improving the centering accuracy before stacking.

[0020] (2) By using this utility model, the support is set as an inclined bearing frame and an adjustable support foot is set on one side bottom, so that the tilt angle of the support can be precisely adjusted and locked within a predetermined range, thereby adapting to different palletizing station heights and conveying drop differences, avoiding the centering error caused by the fixed tilt angle or the problem of mismatch with the upper equipment.

[0021] (3) By using this utility model, replaceable rollers are set at the contact part between the guide plate and the conveyed object, which can significantly reduce contact friction, reduce the wear rate of the bag body and reduce the damage to the packaging surface, solve the problem of damage and high wear caused by direct friction of the fixed plate, and simplify the maintenance and replacement of vulnerable parts.

[0022] (4) Through this utility model, the drive shaft is rigidly connected to the power motor coaxially through the reduction mechanism, which achieves high power transmission efficiency, reliable transmission of starting torque and shock buffering effect, reduces the instantaneous impact on the gearbox and bearings, and extends the service life of transmission components. At the driven shaft end, a tensioning device consisting of a fixed plate, adjusting bolts and adjusting blocks is adopted to achieve controllable fine adjustment of the driven shaft position and precise determination of the conveyor belt tension, solving the problems of belt slippage, slippage or excessive tightness causing deviation and loss.

Detailed Implementation

[0027] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] Example 1

[0029] like Figures 1-3 As shown, a fully automatic palletizing and conveying device for functional fertilizer includes a support frame 1, a conveying device 2, and a power unit 3. The support frame 1 can support the conveying device 2 and the power unit 3, and the power unit 3 can provide power to the conveying device 2.

[0030] The support frame 1 is an inclined support frame; the conveying device 2 consists of a drive shaft 21, a driven shaft 22, and a conveyor belt 23, which is closed and wrapped between the drive shaft 21 and the driven shaft 22 to lift fertilizer from the bottom to the top of the support frame; the power unit 3 consists of a power motor 31 and a reduction mechanism 32, which transmits power to the drive shaft 21. All parts are connected by welding, flanges, or bolts to form a whole.

[0031] Reference Figure 1-3 The support 1 adopts a rectangular frame structure welded from rectangular cross-section steel pipes or channel steel. In this embodiment, it adopts longitudinal beams on both sides, cross beams connecting the longitudinal beams on both sides, and connecting beams.

[0032] The bracket 1 can fix the conveying device 2, which includes a drive shaft 21, a driven shaft 22, and a conveyor belt 23.

[0033] The longitudinal beams on both sides are equipped with a drive shaft 21 at their top, which can pass through the top of the longitudinal beams. The bottom of the two longitudinal beams are connected by a crossbeam, which is located at the bottom of the longitudinal beams. One end of the crossbeam extends horizontally, and a driven shaft 22 is located at the end of the extension. The end of the crossbeam extension is connected to the position where the drive shaft 21 is located at the top of the longitudinal beam by a connecting beam, and a protective cover 112 is provided on the outside of the connecting beam. The support plate of the protective cover 112 is welded or bolted to the bracket 1, so that the protective cover covers the transmission part and is bolted to form a detachable structure for easy maintenance.

[0034] The side view of bracket 1 is triangular, and it is installed at a certain tilt angle. A support foot can be provided on one side of bracket 1, which can adjust the tilt angle of bracket 1. In this embodiment, the support foot is made of a screw with a locking nut. By adjusting the screw, the height of that side can be changed, thereby fine-tuning the tilt angle of the bracket.

[0035] In this embodiment, the support leg only utilizes its telescopic function, and all support structures capable of telescopic function are within the protection scope of this embodiment.

[0036] In another embodiment, the bracket 1 can be fixed to the inclined surface by bolts, and the tilt angle of the bracket 1 can be changed by adjusting the tilt angle of the inclined surface.

[0037] In this embodiment, four protective covers 112 are provided, with two protective covers 112 arranged from bottom to top on both sides of the conveying device 2. The two symmetrical protective covers 112 at the top are equipped with guide devices 11. In this embodiment, the guide devices 11 are guide plates 111, with the two guide plates 111 respectively positioned on one side of the protective cover 112 near the top of the conveying device 2, near the conveying side of the conveying device 2. The two guide plates 111 are symmetrically arranged on both sides of the conveyor belt 23 from the middle to the top of the support 1. The guide plates 111 are bent or flat components, mostly rectangular in cross-section, gradually narrowing from bottom to top along the conveying direction, with the top spacing smaller than the bottom spacing, forming a gradually narrowing guide channel. The guide plates 111 are fixed to the top side of the protective cover 112, with their lower starting position located in the middle of the conveyor belt 23's travel path, and their upper end extending to near the top of the conveyor belt.

[0038] In this embodiment, to reduce friction and wear when in contact with fertilizer packaging bags or containers, rollers can be arranged on the side of the guide plate 111 at the point of contact with fertilizer. The rollers can be mounted on the guide plate bracket via bearings and can be replaced.

[0039] In this embodiment, the protective cover 112 is a box-shaped shell covering the conveyor belt 23, made of bent steel plate or aluminum plate, and has a rectangular crown-shaped covering structure. The protective cover 112 can prevent dust from entering the transmission mechanism, protect the operators, and provide a supporting position for the installation of the guide plate.

[0040] In this embodiment, the conveying device 2 includes a drive shaft 21, a driven shaft 22, and a conveyor belt 23. Both the drive shaft 21 and the driven shaft 22 are roller-type components, employing a hollow or solid roller structure, with bearing seats mounted at both ends, and flanges or keyways at the shaft ends, enabling connection to a reduction mechanism or adjustment device.

[0041] During installation, the drive shaft 21 is fixedly assembled in the bearing housing at one end of the bracket, and the bearing housing is fixed to the crossbeam or end plate of the bracket by bolts; the driven shaft 22 is assembled at the other end of the bracket, and one end or bottom of it is connected to the bracket through the adjustment device 4, so that it can move within a certain range to realize the tension adjustment of the conveyor belt.

[0042] The drive shaft 21 is driven by the power unit 3, which drives the conveyor belt 23 to move along the closed loop; the driven shaft 22 serves as a tensioning and rotating drum, ensuring that the conveyor belt and the conveyed object maintain stable contact on the inclined support.

[0043] The conveyor belt 23 is a closed loop belt, made of wear-resistant and corrosion-resistant materials, such as rubber, PVC, PU, ​​or canvas composite belts; in this embodiment, rubber is used. The conveyor belt 23 can be fitted with a fiber core layer according to load characteristics. The surface of the conveyor belt 23 can be patterned or have rubber blocks to increase friction and anti-slip properties.

[0044] The conveyor belt 23 is arranged around the drive shaft 21 and the driven shaft 22, and runs along the vertical path of the inclined support 1. A support plate can be added to the support 1 to support the return section and prevent the belt surface from sagging.

[0045] The power unit 3 consists of a power motor 31 and a reduction mechanism 32. In this embodiment, the power motor 31 is an electric asynchronous motor and the reduction mechanism 32 is a gear reducer.

[0046] Reference Figure 1-2 The output shaft of the reduction mechanism 32 is connected to the drive shaft 21 via a flange, using a coaxial connection. The output shaft end of the reduction mechanism 32 is fitted onto the keyway pre-reserved in the drive shaft 21. The main body of the reduction mechanism 32 is fixed to the side of the bracket 1 using anchor bolts, and the power motor 31 is directly fixed to the input end of the reduction mechanism. The power transmission path is: power motor 31, reduction mechanism 32, drive shaft 21, conveyor belt 23.

[0047] The adjustment device includes a fixing plate 41, adjusting bolts 42, and adjusting blocks 43. The fixing plate 41 is made of thick steel plate and is fixed to the side of the bracket 1 by bolts or welding. The fixing plate 41 has two through holes, which can accommodate the adjusting bolts 42 and are used for assembly guidance.

[0048] The adjusting bolt 42 is a long threaded bolt that can pass through the hole in the fixing plate 41 and form a threaded engagement with the adjusting block 43. Rotating the adjusting bolt 42 can control the adjusting block 43 to move along the bolt axial direction. A locking nut and anti-loosening washer are provided on the outside of the adjusting bolt 42. The locking nut can lock the adjusting bolt 42.

[0049] Adjusting block 43 is a clamping component connected to the end of driven shaft 22. The connection between adjusting block 43 and driven shaft 22 allows the driven shaft 22 to move radially or axially as the adjusting block 43 moves along the direction of the fixed plate, thereby changing the tension of the conveyor belt 23. The adjusting block and driven shaft should have a sliding or clamping structure that does not restrict axial rotation.

[0050] During installation: Rotate the adjusting bolt 42 to move the adjusting block 43 backward or forward, thereby changing the radial distance between the driven shaft 22 and the driving shaft 21 to achieve the required tension; after adjustment, tighten the lock nut to prevent loosening.

[0051] In this embodiment, the two ends of the drive shaft 21 are mounted into the drive shaft supports reserved on the bracket 1 via rolling bearings. The shaft ends are fixedly connected to the output shaft of the reduction mechanism 32 via flanges. The reduction mechanism 32 is fixed to the outside of the bracket 1. The power motor 31 is installed on the input side of the reduction mechanism 32 and is fixedly connected to the bracket 1 by bolts.

[0052] The driven shaft 22 is also mounted on the driven shaft support reserved on the bracket 1 via a bearing, and an adjustment block 43 can be provided on the outer side of the driven shaft 22. In this embodiment, adjustment blocks 43 are provided on both sides of the driven shaft 22, and the adjustment blocks 43 interact with the fixing plate 41 through the adjustment bolts 42 to achieve shaft displacement.

[0053] The guide plate 111 is fixed to the protective cover 112 by bolts or welding, and its lower end is aligned with the center line of the conveyor belt to ensure guiding effect. Rollers are provided on the side of the guide plate 111, and the connection of the rollers adopts a replaceable bearing pin structure for easy maintenance.

[0054] The protective cover 112 is fixed to the bracket by bolts and has an inspection port at an appropriate location. The inspection port is fixed to the locking device by a hinge.

[0055] In this embodiment, the gradually narrowing guide plate 111, which is equipped with a guide structure 11 with rollers, can effectively guide the fertilizer bag longitudinally to the center line of the conveyor belt, reduce lateral deviation, improve the centering accuracy of the upper palletizing, and reduce the packaging damage rate.

[0056] The adjustable tilt angle of bracket 1, combined with the tensioning device of conveyor belt 23, allows the equipment to adapt to fertilizer bags of different specifications and different production line station heights, making it highly versatile.

[0057] The reduction gear 32 is rigidly connected to the drive shaft 21 and supported by bearing housings to ensure stable torque transmission. The conveyor belt 23 is made of wear-resistant material, suitable for conveying bagged fertilizers. The adjustment device 4 uses bolt-type adjustment, which is intuitive to operate and can be locked. The protective cover 112 covers the conveyor belt 23 to reduce the risk of personnel contact.

[0058] 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, and various changes and modifications can be made without departing from the spirit and scope of this utility model.
