Technical Field
[0001] This utility model relates to the field of chemical material preparation technology, and in particular to a waste recycling mechanism for granulation equipment. Background Technology
[0002] Currently, in the chemical industry, when manufacturing pellets, if a fixed-length material strip is used for rotary cutting or roller granulation, there is always a deviation between the position of the conveyor strip and the position of the cutter (the material strip is laid out along the width of the conveyor belt, and the cutter cuts the material strip). This results in the two ends of the material strip being cut (rolled) into waste products (the middle part of the material strip is cut into good products). The waste products will go through other processes along with the good products, which will reduce the yield rate. Utility Model Content
[0003] In view of this, the purpose of this utility model is to provide a waste recycling mechanism for a pelletizing equipment, so as to solve the technical problem in the prior art that waste products are formed at both ends of the material strips after the material strips are cut or rubbed to obtain pellets, and the waste products are transported together with the good products, resulting in a reduction in the yield rate.
[0004] To achieve the above objectives, this utility model provides a waste recycling mechanism for a granulation equipment, including a waste separation partition. The waste separation partition is disposed along the transmission direction of the conveyor belt and close to the end of the conveyor belt. The waste separation partition divides the conveyor belt into a good product transmission channel and a waste product transmission channel, with the waste product transmission channel located on both sides of the good product transmission channel.
[0005] Optionally, the waste separation partition includes four pieces: a first waste separation partition, a second waste separation partition, a third waste separation partition, and a fourth waste separation partition. The first and second waste separation partitions are disposed on the side near the conveyor belt, forming a first waste transmission channel between them. The third and fourth waste separation partitions are disposed on the opposite side near the conveyor belt, forming a second waste transmission channel.
[0006] Optionally, it also includes a fixed beam, which is fixedly disposed above the conveyor belt along the width direction of the conveyor belt. The fixed beams are arranged in pairs at a preset distance and are parallel to each other. The two ends of the first waste separation partition, the second waste separation partition, the third waste separation partition and the fourth waste separation partition are all installed on the fixed beam.
[0007] Optionally, the first waste separation partition and the third waste separation partition are fixedly mounted on the fixed beam, and the second waste separation partition and the fourth waste separation partition are slidably mounted on the fixed beam.

[0013] Optionally, the good product recycling channel is formed by an inclined material distribution chute plate, and the inclination of the good product recycling channel is less than that of the first waste recycling channel and the second waste recycling channel.
[0014] The waste recycling mechanism for the pelleting equipment provided by this utility model has the following technical effects:
[0015] This waste recycling mechanism includes a waste separation partition, which is positioned along the conveyor belt's transport direction and near its end. The partition divides the conveyor belt into a good-product transport channel and a waste transport channel, with the waste transport channel located on either side of the good-product transport channel. This invention achieves automatic sorting by directly installing the waste separation partition at the end of the conveyor belt, utilizing the difference in material movement trajectories. This avoids the need for additional sorting equipment, enabling real-time separation of good and waste products during transport, effectively preventing waste from mixing into subsequent processes and improving the purity of collected good products. The sorting process does not interrupt the production flow, and the separation action is completed synchronously with material transport, significantly improving sorting efficiency.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0024] In existing technologies, the chemical industry uses fixed-length material strips for rotary cutting or roller granulation when manufacturing pellets. The material strips are laid out along the width of the conveyor belt, and a cutter cuts them. Due to a misalignment between the position of the material strip and the position of the cutter, the two ends of the material strip are often cut off as waste, while the middle part becomes a good product. The waste products enter subsequent processes along with the good products, resulting in a decrease in the yield rate.
[0025] To address the aforementioned issues, the inventors observed a spatial difference in the distribution of defective and good products on the conveyor belt, with defective products concentrated at both ends of the material strip, while good products were located in the middle area. Based on this, they proposed a method of physically separating and guiding products from different areas. Considering that the end of the conveyor belt is a natural node for material diversion, a separating structure was chosen to be installed near the end of the conveyor belt, utilizing the difference in transmission direction and spatial location to achieve automatic sorting.
[0026] Therefore, as Figure 1-3 As shown, the present invention proposes a waste recycling mechanism for a granulation equipment, which includes a waste separation partition. The waste separation partition is arranged along the transmission direction of the conveyor belt and close to the end of the conveyor belt. The waste separation partition divides the conveyor belt into a good product transmission channel c and a waste product transmission channel, with the waste product transmission channel located on both sides of the good product transmission channel c.
[0027] The waste separation baffle is a separating component parallel to the conveyor belt's transmission direction. It can be made of metal plates or polymer composite materials, and its height can cover the material's trajectory. This baffle separates waste and good products along different paths through spatial separation. The baffle is installed near the critical area where material leaves the conveyor belt, typically at a distance of 5-50 cm from the belt end. The good product transmission channel (c) is a continuous transmission area in the middle of the conveyor belt not obstructed by the baffle; good products, being centrally located, can directly enter the collection device through this channel. The waste transmission channel consists of independent guiding areas located on either side of the good product transmission channel (c), formed by side baffles, used to collect waste products that are off-center.
[0028] Specifically, during the cutting process of the material strip, the good products in the middle fall into the good product conveying channel c, and move with the conveyor belt, entering the good product collection device through the good product conveying channel c; the waste products on both sides, due to being off the central axis, fall into the waste product conveying channel, and move with the conveyor belt.
[0029] This invention achieves automatic sorting by directly installing a sorting structure at the end of the conveyor belt, utilizing the differences in the material's own movement trajectory, thus avoiding the need for additional sorting equipment. Through this technical solution, this application realizes the instantaneous separation of good and bad products during the conveying process, effectively preventing bad products from mixing into subsequent processes and improving the purity of good product collection. The sorting process does not require interruption of the production flow, and the separation action is completed synchronously with material transfer, significantly improving sorting efficiency.
[0030] Furthermore, such as Figure 1-3 As shown, the waste separation partition includes four pieces, namely the first waste separation partition 1, the second waste separation partition 2, the third waste separation partition 3, and the fourth waste separation partition 4. The first waste separation partition 1 and the second waste separation partition 2 are arranged on the side close to the conveyor belt, and a first waste transmission channel a is formed between the first waste separation partition 1 and the second waste separation partition 2. The third waste separation partition 3 and the fourth waste separation partition 4 are arranged on the opposite side close to the conveyor belt, and the third waste separation partition 3 and the fourth waste separation partition 4 form a second waste transmission channel b.
[0031] The first waste transport channel a and the second waste transport channel b are independent waste flow paths formed by partitions. Specifically, the channel width can be controlled by adjusting the partition spacing so that the waste at both ends of the material strip enters the corresponding channel respectively.
[0032] Specifically, the four waste separation partitions are divided into two groups, respectively located at the edges of both sides of the conveyor belt, with each group containing two adjacent partitions. The first waste transfer channel a consists of the first waste separation partition 1 and the second waste separation partition 2 located on the side closest to the conveyor belt, while the second waste transfer channel b consists of the third waste separation partition 3 and the fourth waste separation partition 4 located on opposite sides. When the material strip is cut by the cutter, the waste at both ends falls off and is discharged along the waste transfer channels on both sides, while the good products in the middle fall off and continue to be conveyed through the central area.
[0033] To fix the waste separation partition, a fixing beam 5 is also included. The fixing beam 5 is fixedly installed above the conveyor belt along the width direction of the conveyor belt. The fixing beams 5 are arranged in pairs at a preset distance and are parallel to each other. The two ends of the first waste separation partition 1, the second waste separation partition 2, the third waste separation partition 3 and the fourth waste separation partition 4 are all installed on the fixing beam 5.
[0034] The fixed beam 5 is a supporting component extending laterally along the conveyor belt. It can be made of channel steel or I-beams and serves as the mounting base for the waste separation partition. The preset spacing refers to the distance between two parallel fixed beams 5, which can be adjusted according to the partition layout requirements; for example, the spacing range can be 50-200 mm. The waste separation partition is installed on the fixed beam 5 by connecting its two ends to the fixed beam 5 with bolts or clips. Position adjustment can be achieved using sliding rails or positioning holes.
[0035] Specifically, after the fixed beams 5 are fixed laterally along the conveyor belt, four waste separation partitions are respectively straddled between the pairs of fixed beams 5. The installation position of the waste separation partitions is stably supported by the preset spacing of the fixed beams 5, ensuring that the separation boundary between the good product conveying channel c and the waste product conveying channel remains fixed. When the material strip is cut, the good and waste products are guided to the corresponding conveying channels by the separation partitions during the falling process. The rigid support of the fixed beams 5 can prevent the waste separation partitions from shifting due to material impact.
[0036] Furthermore, the first waste separation partition 1 and the third waste separation partition 3 are fixedly mounted on the fixed beam 5, while the second waste separation partition 2 and the fourth waste separation partition 4 are slidably mounted on the fixed beam 5.
[0037] The waste separation partition is slidably mounted on the fixed beam 5, and the connection between the partition and the fixed beam 5 is movable. Specifically, it can be achieved by using a sliding rail and slider structure, which facilitates the adjustment of the partition spacing to adapt to the width of the first waste transfer channel a and the second waste transfer channel b.
[0038] Specifically, the first waste separation partition 1 and the third waste separation partition 3 are fixedly connected to the fixed beam 5 to form a stable boundary separation structure. The second waste separation partition 2 and the fourth waste separation partition 4 move laterally along the fixed beam 5 via a sliding mechanism. The operator can adjust the distance between them according to the actual width of the material strip, thereby controlling the effective width of the waste conveying channel. When the waste area changes due to positional deviation of the material strip, sliding the second waste separation partition 2 and the fourth waste separation partition 4 can quickly adjust the waste collection range, ensuring that waste and good products are accurately separated during the conveying process.
[0039] In addition, both the second waste separation partition 2 and the fourth waste separation partition 4 are bent toward the central axis of the conveyor belt.
[0040] The second waste separation baffle 2 is a sliding separation component located on one side of the good product conveying channel. It can be made of stamped stainless steel sheet and its position is adjusted by a slide rail on the fixed beam 5 to guide waste products in a specific direction. The fourth waste separation baffle 4 is a sliding separation component located on the other side of the good product conveying channel. It can adopt a symmetrical structure design with the second waste separation baffle 2 and achieve synchronous adjustment through the same slide rail mechanism to coordinate the control of the waste conveying channel width. The bending towards the central axis of the conveyor belt forms a bent structure at the edge of the baffle that slopes towards the center of the conveyor belt. This can be achieved using sheet metal processing with a bending angle of 30-60 degrees, and the inclined guide surface guides the waste products into the waste conveying channel.
[0041] Specifically, after the material strip is cut, the good products move along the central area of the conveyor belt, while the waste products generated at both ends shift outwards due to inertia. The second waste separation baffle 2 and the fourth waste separation baffle 4 of the bent structure form guide ramps. After contacting the ramps, the waste products slide into the first waste transfer channel a and the second waste transfer channel b on both sides along the bending direction. The bending angle can be adjusted according to the material flow characteristics. For example, a larger bending angle can be used for viscous materials with poor flowability to enhance the guiding effect.
[0042] In a preferred embodiment, a first waste collection channel a1 is provided at the end of the first waste transport channel a, and a second waste collection channel b1 is provided at the end of the second waste transport channel b.
[0043] The first waste transfer channel a is the space formed between two waste separation partitions on one side of the conveyor belt. It can be implemented using an adjustable-spacing guide plate structure to guide the waste material generated by the cutters on both sides of the material strip. The second waste transfer channel b is the space formed between two waste separation partitions on the other side of the conveyor belt. It can also be implemented using an adjustable-spacing guide plate structure to collect the waste material generated by the cutters on the other side. The first waste recycling channel a1 and the second waste recycling channel b1 are independent collection devices installed at the ends of the first waste transfer channel a and the second waste transfer channel b, respectively. They can be implemented using inclined chutes or closed pipe structures to directly guide the waste material to an external collection container.
[0044] Specifically, a first waste recycling channel a1 and a second waste recycling channel b1 are set at the end of the conveyor belt. After the cut material strip is separated by the waste separation baffle, the waste on both sides of the material strip enters the recycling channel set at the end through the corresponding waste transfer channel. The first waste recycling channel a1 receives the waste from one side of the conveyor belt, and the second waste recycling channel b1 receives the waste from the other side. The two recycling channels form a spatial isolation with the good product transfer channel c, avoiding the mixing of waste with good products at the end of the conveyor belt.
[0045] In this embodiment, both the first waste recycling channel a1 and the second waste recycling channel b1 end in a waste outlet 8. The waste outlet 8 is a channel end structure used for the centralized discharge of substandard materials. Specifically, it can be implemented using a metal guide channel or a plastic slide, with an inclined angle design that allows the waste to automatically slide into the collection container. This structure prevents waste from mixing with good products at the outlet.
[0046] Specifically, after the material strip is cut, the resulting waste enters the first waste recycling channel a1 and the second waste recycling channel b1 along the waste conveyor channel. The directional guidance function of the end waste outlet 8 allows the waste to slide directly off the production line, while the good products enter the good product recycling channel c1 through the good product conveyor channel c. The independent setting of the waste outlet 8 ensures that waste and good products are completely separated at the end, eliminating the need for manual sorting.
[0047] In a preferred embodiment, a good product recycling channel c1 is provided at the end of the good product conveying channel c, and a first waste product recycling channel a1 and a second waste product recycling channel b1 are located on both sides of the good product recycling channel c1. The good product recycling channel c1 is a guide structure for collecting qualified products. Specifically, it can be implemented by forming an inclined channel using a material distribution chute plate 6. The material descent speed is controlled by adjusting the inclination angle of the chute plate to avoid collision damage to the good products.
[0048] Specifically, at the end of the conveyor belt, the good product recycling channel c1 is located on the central axis of the transmission path, while the first waste product recycling channel a1 and the second waste product recycling channel b1 are symmetrically distributed on its left and right sides. When good products enter the end of the conveyor belt, they are directly guided to the collection area through the good product recycling channel c1; at the same time, waste products on both sides of the conveyor belt are guided by waste separation partitions and enter the waste recycling channels on both sides respectively.
[0049] Furthermore, the end of the good product recycling channel c1 is designated as the good product outlet 7. The good product outlet 7 is a material collection device at the end of the good product recycling channel c1, which can be implemented using a guide chute. The end of the good product conveying channel c1 is connected to subsequent processing equipment via the good product outlet 7. After the good product material enters the good product recycling channel c1 along the conveyor belt, it slides towards the good product outlet 7 under the inclined guiding action of the material distribution chute plate 6, while the waste conveying channels on both sides guide the waste material to independent recycling areas.
[0050] In some specific embodiments, the good product recycling channel c1 is formed by an inclined material distribution chute plate 6, and the inclination of the good product recycling channel c1 is less than that of the first waste recycling channel a1 and the second waste recycling channel b1.
[0051] The material distribution chute plate 6 is a plate-like structure that guides the sliding of materials through an inclined angle. Specifically, it can be made of a smooth metal plate or a polymer material plate. Its inclined angle directly affects the sliding speed and direction of the materials. The degree of inclination is the size of the angle between the material distribution chute plate 6 and the horizontal plane. Specifically, it can be achieved by adjusting the position of the fixing bolts or the height difference of the mounting bracket. A smaller degree of inclination can slow down the sliding speed of the materials, while a larger degree of inclination can accelerate the material detachment.
[0052] Specifically, the good product recycling channel c1 is formed by the inclined surface of the material distribution chute plate 6, and its inclination angle is designed to be smaller than that of the waste product recycling channel. Good products, due to their slower sliding speed during transport, can smoothly enter the collection area of subsequent processes, while waste products, due to their faster sliding speed, quickly leave the conveying area through the waste recycling channel. The difference in inclination of the material distribution chute plate 6 allows good and waste products to naturally separate during their descent, preventing waste products from being retained or mixed into the good product channel.
