Description

Technical Field

[0001] The present invention belongs to the technical field of conveying devices, relates to a sorting device, and particularly relates to a double-layer sorting machine. Background Art

[0002] A sorting machine is an automated device mainly used for sorting the postures of material products during industrial production to improve the efficiency of the production line and ensure the overall stable operation of the system. In the prior art, due to the characteristics that the bagged materials are easily deformed by force, problems such as tilting or stacking are likely to occur, which will affect the subsequent processes. And the existing sorting devices are often limited by the feeding speed, thus affecting the overall sorting efficiency. For this reason, people have carried out long-term explorations and proposed various solutions.

[0003] For example, a Chinese patent document discloses a modular bagged product sorting and conveying device [Application No.: CN202111448127.6], which includes a dual-power roller mechanism, a speed measuring mechanism and a controller. The dual-power roller mechanism includes a roller frame, rollers, a first motor, a second motor, a first transmission assembly, a second transmission assembly and a controller. A plurality of the rollers are respectively rotatably connected to the roller frame and arranged in parallel. Each roller is axially provided with a first barrel section and a second barrel section that can rotate independently of each other and do not interfere with each other. The first motor drives the first barrel sections of each roller to rotate simultaneously through the first transmission assembly, and the second motor drives the second barrel sections of each roller to rotate simultaneously through the second transmission assembly. A plurality of the dual-power roller mechanisms are detachably arranged in sequence front and back and spliced to form a conveyor belt. The overall structure is simple and the length of the conveyor belt can be freely adjusted according to requirements.

[0004] Although the above solution has a good sorting effect, it cannot adapt to high-speed feeding methods, and the overall efficiency is low. And when feeding at high speed, it will cause the materials to be messy, and the flat soft bags will be in various states. The above solution has a poor sorting effect on non-flat bags. On the other hand, the single-line structure design makes the floor area large and it is difficult to install and use. Summary of the Invention

[0005] The object of the present invention is to provide a double-layer sorting machine with higher efficiency for the above problems.

[0006] To achieve the above object, the present invention adopts the following technical solutions: A double-layer sorting machine, including a frame, on which there are two modular bagged product sorting and conveying devices distributed up and down. At the feeding end of the upper modular bagged product sorting and conveying device, there is a feeding mechanism for radial feeding. Between the feeding mechanism and the modular bagged product sorting and conveying device, there is a blanking inclined plate that can make the falling flat bag body enter between the conveying roller surface and the inner baffle of the upper modular bagged product sorting and conveying device. Between the feeding end and the discharging end of the modular bagged product sorting and conveying device, there is a sorting mechanism that can flatten the flat bag body in a non-flattened state onto the conveying roller surface. Between the discharging end of the upper modular bagged product sorting and conveying device and the lower modular bagged product sorting and conveying device, there is an arc-shaped transition cover that can be used to form an arc-shaped guiding channel.

[0007] The cooperation between the feeding mechanism and the blanking inclined plate enables the flat bag body to enter the upper modular bagged product sorting and conveying device at a high speed, avoiding the dropping of the bag body, and having the effect of improving the overall sorting efficiency. At the same time, the design of the sorting mechanism can ensure that the flat bag body in a non-flattened state is flattened onto the conveying roller surface, thus ensuring the sorting effect. The arc-shaped transition cover provided between the upper and lower modular bagged product sorting and conveying devices forms an arc-shaped guiding channel, enabling the bagged products to smoothly transition between the two conveying devices, realizing the function of double-layer sorting, and achieving the effects of improving the sorting effect quality and reducing the floor area.

[0008] In the above double-layer sorting machine, the modular bagged product sorting and conveying device includes a plurality of conveying roller mechanisms arranged side by side and double-power roller mechanisms that are sequentially spliced on the frame to form a conveying roller surface.

[0009] In the above double-layer sorting machine, the sorting mechanism includes a vertical material scraping block and a shaping roller assembly arranged between the feeding end and the discharging end of the modular bagged product sorting and conveying device. The vertical material scraping block is arranged on the inner baffle and is close to the conveying roller surface of the modular bagged product sorting and conveying device but does not contact it. The vertical material scraping block is arranged on the inner baffle and is close to the conveying roller surface of the modular bagged product sorting and conveying device but does not contact it, which can play a role in guiding the bag body to be pre-turned over, facilitating the improvement of the shaping effect of the subsequent shaping roller assembly, and also avoiding the bag body being stuck in the gap during the conveying process.

[0010] In the above double-layer sorting machine, the vertical material scraping block is located at the front end and the rear end of the feeding end and the discharging end of the modular bagged product sorting and conveying device respectively. An inlet inclined surface is provided at the front end of the vertical material scraping block, which can make its thickness gradually decrease from the rear end to the front end. An arc-shaped concave turning inclined surface that gradually inclines outward is also provided on the vertical material scraping block, starting from below the rear end of the inlet inclined surface and above the rear end of the vertical material scraping block. An arc-shaped thickened anti-injury edge is provided between the top surface of the vertical material scraping block and above the arc-shaped concave turning inclined surface. The inlet inclined surface provided at the front end of the vertical material scraping block can more conveniently guide the bag into the sorting area. The setting of the arc-shaped concave turning inclined surface enables the bag to be further flipped and sorted under the action of the turning inclined surface while being guided by the vertical material scraping block. The arc-shaped thickened anti-injury edge can prevent the bag from being damaged due to excessive pressure or friction during the sorting process.

[0011] In the above double-layer sorting machine, a vertical material scraping block height adjustment component is provided between the vertical material scraping block and the inner baffle. The setting of the vertical material scraping block height adjustment component enables the height of the vertical material scraping block to be adjusted according to actual needs. Precise control of the gap between it and the conveying roller surface helps to reduce the jamming and accumulation of bags.

[0012] In the above double-layer sorting machine, the shaping roller assembly includes a mounting plate and a shaping roller. The shaping roller is sleeved on a roller shaft. One end of the roller shaft is connected to the mounting plate that is axially limited and circumferentially rotatable. Anti-slip lines that can contact the surface of the bag are provided on the outer wall of the shaping roller. The roller shaft is connected to a conveyor belt driver on one side through a conveyor belt. At least two strip-shaped height adjustment holes for fixing on the frame are provided on the mounting plate. The roller shaft passes through the inner baffle, and a vertically arranged roller shaft height adjustment hole is provided on the inner baffle. The design of the anti-slip lines enables the shaping roller to effectively flatten the bag when rotating, ensuring that the bag remains in a flat state during transportation. The shaping roller assembly can flexibly adjust the height of the shaping roller through the strip-shaped height adjustment holes and the roller shaft height adjustment holes on the mounting plate. This helps to improve the adaptability and flexibility of the equipment.

[0013] In the above double-layer sorting machine, the shaping roller includes a cylinder body. A number of weight reduction units are radially distributed on the cylinder body. The weight reduction units include a number of weight reduction holes that are circumferentially distributed and axially penetrate the cylinder body. The weight reduction holes of adjacent two weight reduction units are arranged in a staggered manner; The anti-slip pattern described above includes a number of anti-slip protrusions that are evenly distributed circumferentially and axially arranged on the outer wall of the shaping roller, and the anti-slip protrusions are integrally connected to the shaping roller. The weight reduction holes of adjacent weight reduction units are arranged in a staggered manner, avoiding the reduction of structural strength caused by the alignment of hole positions, and ensuring that the cylinder body can still maintain sufficient rigidity and strength while reducing weight. The anti-slip protrusions are integrally connected to the cylinder body, avoiding the possible loosening or falling off problems in the traditional split structure, and improving the stability and reliability of the structure.

[0014] In the above double-layer finishing machine, bearing seats sleeved on the roller shafts are provided on both sides of the mounting plate. Bearings are provided between the bearing seats and the roller shafts. The roller shafts are fixedly connected to the inner rings of the bearings. Belt pulleys that are circumferentially limitedly connected to the roller shafts are provided on the roller shafts. The belt pulleys are connected to the driving wheels of the belt conveyor driver through the conveyor belts. Sleeve bushes are provided between the two ends of the belt pulleys and the inner rings of the two ends of the bearings. The sleeve bushes are arranged between the two ends of the belt pulleys and the inner rings of the bearings, which can effectively limit the axial displacement of the belt pulleys and ensure the stability of the transmission system. The belt pulleys are circumferentially limitedly connected to the roller shafts, which can ensure no relative sliding during the power transmission process and improve the transmission efficiency.

[0015] In the above double-layer finishing machine, the belt conveyor driver is a driving motor. A tensioning and distance-adjusting structure is provided between the belt conveyor driver and the mounting plate. The tensioning and distance-adjusting structure includes at least two strip-shaped distance-adjusting holes provided on the mounting plate. The belt conveyor driver is fixed to the mounting plate through bolts passing through the strip-shaped distance-adjusting holes. Through at least two strip-shaped distance-adjusting holes and bolt fixation, the force on the driving motor is more uniform, reducing the stress concentration caused by single-point fixation, and improving the structural stability.

[0016] In the above double-layer finishing machine, a baffle is provided at the feeding end of the upper modular bagged product finishing and conveying device. A distance-adjusting horizontal hole parallel to the roller body of the modular bagged product finishing and conveying device is provided on the baffle. An arc-shaped hole is provided outside the upper side of the distance-adjusting horizontal hole. One side of the lower end of the blanking inclined plate is connected to the distance-adjusting horizontal hole through a bolt. A strip-shaped slope-adjusting hole is provided on one side of the upper end of the blanking inclined plate. The upper end of the blanking inclined plate and the baffle are fixed through bolts passing through the strip-shaped slope-adjusting hole and the arc-shaped hole. The lower end of the blanking inclined plate is connected to the distance-adjusting horizontal hole through a bolt and can move along the direction of the horizontal hole to adjust the lateral position of the blanking point on the conveyor belt, avoiding the falling of materials during high-speed feeding and ensuring that the materials efficiently and accurately fall into the center of the conveyor belt.

[0017] In the above double-layer finishing machine, the feeding mechanism is a vibrating feeder, and a feeding channel is provided at the top of the vibrating feeder; It is fixed by the side baffle and the inner baffle, and the upper end of the arc-shaped transition cover is higher than the conveying roller surface of the upper modular bagged product finishing and conveying device, and the lower end of the arc-shaped transition cover is located on the conveying roller surface of the lower modular bagged product finishing and conveying device; An outlet roller module is provided between the outlet end of the lower modular bagged product sorting and conveying device and the inner baffle. The width of the outlet roller module is smaller than the width of the lower modular bagged product sorting and conveying device, and the outlet roller surface of the outlet roller module slopes downward gradually from the inner end to the outer end. A rejection receiving hopper is provided between the lower part of the outlet roller module and the outlet end of the lower modular bagged product sorting and conveying device. The upper end of the arc transition cover is higher than the upper conveyor belt roller surface, and the lower end contacts the lower conveyor belt roller surface, forming a natural slope, which can reduce the impact of material dropping. The receiving hopper is located below the outlet roller module and directly receives the materials that need to be rejected, which can prevent waste from scattering.

[0018] Compared with the existing technology, the advantages of this double-layer sorting machine are as follows: 1. It is provided with a specially designed vertical material scraping block, which can turn over non-flat bag bodies and has a better sorting effect. 2. It has a feeding mechanism that prevents dropping, can feed at a higher speed, and has a higher sorting efficiency. 3. The double-layer conveying structure design makes the structure more compact and has a high space utilization rate. 4. It has a variety of distance adjustment designs, and the equipment has higher adaptability. Description of the Drawings
