Description

Technical Field

[0001] The utility model belongs to the technical field of fertilizer production, and particularly relates to a sealing device for the production and processing of rice blended fertilizers. Background Art

[0002] Rice blended fertilizer is a fertilizer prepared by premixing different types of fertilizers in a certain proportion. Compared with single fertilizers, blended fertilizers have certain cost advantages and can reduce the input costs of farmers. After mixing, it is weighed and bagged on the packaging production line, and then the bag mouth is sealed.

[0003] Traditional fertilizer bag sealing can be achieved by using a five-axis / six-axis industrial robot for picking and placing, and then using methods such as gluing, folding and ironing, sewing and heat sealing for sealing. Among them, the gluing method and the folding and ironing method are relatively complex to operate. The sewing method involves threading a sewing thread through the bag mouth, which is likely to leave holes or gaps, causing air leakage. After air enters, it gets damp, so it is not widely used.

[0004] In the current rice blended fertilizer production line, mainly after mixing and quantitative bagging, the bag mouth is clamped from both sides by pressing plates. The heating plate on the back of one of the pressing plates is heated to melt and bond the bag mouth part. However, a small part is likely to fall off and stick to the surface of the pressing plate. Even if an anti-sticking coating is applied to the pressing plate, there is still adhesion and caking under strong extrusion, leaving indentations on the subsequent bag mouths, reducing the yield rate of the sealed fertilizer bags. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a sealing device for the production and processing of rice blended fertilizers, which can scrape off residual caking during short stops to reduce the indentations formed on subsequent bag mouths by the caking, thereby improving the yield rate of fertilizer sealing.

[0006] The specific technical solution adopted by the utility model is as follows:

[0007] A sealing device for the production and processing of a rice blended fertilizer, comprising a feeding conveyor belt. Above the feeding conveyor belt, there are two parallel pressing plates and a driving element for horizontally moving the pressing plates. A door frame fixedly connected to the driving element is fixed outside the feeding conveyor belt. The door frame includes two parallel vertical plates and a horizontal plate fixedly connected to the upper ends of the vertical plates. On the side of each of the two vertical plates close to each other, a vertical movement module is fixed. The output ends of the two vertical movement modules are both fixedly connected with vertical plates. On the side of each of the two vertical plates close to each other, a blocking component is arranged. Along the axial direction, a shovel is fixedly installed at the upper end of each of the two vertical plates. When the two pressing plates are in the open state pushed by the driving element, the shovel is pushed by the vertical plate to clean the caked matter attached to its surface. When cleaning the caked matter, the vertical movement module is started to lift the vertical plate and the shovel. When the two pressing plates are in the open state pushed by the driving element, the shovel is pushed by the vertical plate to clean the caked matter attached to its surface. During the short stop gap of the two pressing plates, the edge of the shovel travels close to the front surface of the pressing plate to scrape off the residual caked matter, reducing the indentation formed by the caked matter pressing on the subsequent bag mouth, so as to improve the yield rate of the fertilizer seal. After reaching the upper edge of the pressing plate, it starts to lower until it resets. At the same time, the fertilizer bags are limited from both sides to support the toppled fertilizer bags without scratching the fertilizer bags.

[0008] As a preferred solution, the blocking component includes a plurality of rubber rollers vertically and rotatably installed on one side of the vertical plate. An interval is reserved between adjacent rubber rollers. At the upper edge of the vertical plate, a receiving groove with an upward opening is fixedly installed. While the rubber rollers rise and fall with the vertical plate, the toppled fertilizer bags can be supported from both sides. The rubber rollers can rotate horizontally and will not scratch the fertilizer bags when idle. At this time, the receiving groove is used to catch the caked matter falling from the edge of the shovel blade, separating the caked matter to prevent it from falling onto the surface of the feeding conveyor belt and the rubber rollers.

[0009] As a preferred solution, two symmetric slopes are integrally installed on the bottom wall of the receiving groove. The connection of the two slopes protrudes upward in the middle of the receiving groove. After the caked matter falls into the receiving groove, it is guided toward both sides of the door frame by the slopes, which is more convenient for discharging.

[0010] As a preferred solution, guide plates extending outward from the feeding conveyor belt are fixedly installed at both ends of the receiving groove. There is an included angle between the guide plates and the vertical plates. The guide plates further limit the caked matter discharged by the slopes, causing these caked matters to fall off deviating from the feeding conveyor belt.

[0011] As a preferred solution, protective nets staggered from the receiving groove are fixedly installed on both sides of the vertical plates. They provide parallel protection from both sides to prevent workers from entering the door frame and a relatively large interval is reserved as the activity space for industrial robots.

[0012] As a preferred solution, the driving element includes two transverse movement modules symmetrically arranged above the feeding conveyor belt. A horizontal straight plate is horizontally fixed at the output end of each of the two transverse movement modules. One end of each of the two horizontal straight plates passes through the vertical plate and is fixedly connected to the back of the pressing plate. The pressing plate is supported by the horizontal straight plate. Once the transverse movement module is started, the two pressing plates can be horizontally moved closer to each other until the bag mouth is clamped, or the two pressing plates can be driven to move away from each other to release the bag mouth.

[0013] As a preferred solution, the length of the shovel is less than the length of the receiving groove. Both corners of the blade of the shovel have a radian. When impacting the caked mass, the chipping of the shovel can be reduced. In particular, the caked mass that is shoveled off can be caught as much as possible by the receiving groove that is longer than the shovel, further reducing the caked mass that flies onto the feeding conveyor belt.

[0014] The technical effects achieved by the present utility model are as follows:

[0015] When the present utility model cleans the caked mass, the vertical movement module is started to lift the vertical plate and the shovel. When the two pressing plates are in the open state pushed by the driving element, the vertical plate is used to push the shovel to clean the caked mass attached to its surface. During the short stop gap of the two pressing plates, the blade of the shovel travels close to the front surface of the pressing plate to scrape off the residual caked mass, reducing the indentation formed by the caked mass pressing on the subsequent bag mouth, thereby improving the yield rate of the fertilizer seal. After reaching the upper edge of the pressing plate, it starts to lower until it returns to the original position. At the same time, the fertilizer bag is limited from both sides, supporting the tilted fertilizer bag without scratching the fertilizer bag.

[0016] When the rubber roller of the present utility model rises and falls with the vertical plate, it can support the tilted fertilizer bag from both sides, and the rubber roller can rotate horizontally and will not scratch the fertilizer bag when idle. At this time, the receiving groove is used to catch the caked mass falling from the blade of the shovel, separating the caked mass to prevent it from falling onto the feeding conveyor belt and the surface of the rubber roller.

[0024] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0025] Rice fertilizer blends typically consist of a variety of fertilizers, including but not limited to organic fertilizers, inorganic fertilizers, and trace element fertilizers. Organic fertilizers, such as humic acid and amino acids, can improve soil structure and fertility. Inorganic fertilizers, such as nitrogen, phosphorus, and potassium, are essential macronutrients for rice growth. Trace element fertilizers, such as zinc, boron, and manganese, although required in smaller quantities, also play an important role in rice growth and development.

[0026] In the production of rice-blended fertilizers, five-axis / six-axis industrial robots for picking and placing materials have been used relatively maturely, saving manual operations, especially in the transfer of toxic and hazardous materials or high-risk operation positions, greatly reducing safety and maintenance costs.

[0027] like Figures 1-5 As shown, a sealing device for the production and processing of rice-blended fertilizer is controlled by a control system based on an industrial computer. It includes a feeding conveyor belt 1, two parallel pressure plates 2 and a driving element for horizontally moving the pressure plates 2 are arranged above the feeding conveyor belt 1, and a heating resistance wire is fixed to the back of the pressure plate 2. This technical solution is a prior art and is not shown in the figure. A door frame 3 fixedly connected to the driving element is fixed to the outside of the feeding conveyor belt 1. The door frame 3 includes two parallel vertical plates and a horizontal plate fixedly connected to the upper ends of the vertical plates. Two in-position sensors are embedded on the upper surface of the horizontal plate for detecting the signal of the two pressure plates 2 reaching the farthest position after separation and transmitting it to the control main board. A vertical movement module 4 is fixed on the side where the two vertical plates are close to each other. The vertical movement module 4 can select a linear module of the GTH5-L5-50-BC-50W model and is connected to the control main board by signal. A vertical plate 5 is fixed to the output end of the two vertical movement modules 4. A blocking component is provided on the side where the two vertical plates 5 are close to each other. A scraper 6 is fixed to the upper end of the two vertical plates 5 along the axial direction.

[0028] After the fertilizer is bagged, it is placed on the belt of the feeding conveyor 1 and transported from one end to the other. When it reaches the middle position, it stops briefly. The driving unit can be started to push the two pressing plates 2 toward the middle to press the bag opening. At the same time, the resistance wire is energized to heat the bag opening to the set temperature, causing it to partially melt and stick together. Then the two pressing plates 2 are separated and returned to a position away from the fertilizer bag in the door frame 3. Part of the molten material falls off and adheres to the front of the pressing plate 2 under the action of extrusion, forming a lump.

[0029] When cleaning lumps, start the vertical movement module 4 to lift the vertical plate 5 and the scraper 6. The two pressure plates 2 are in the open state pushed by the driving element, and the scraper 6 is pushed by the vertical plate 5 to clean the lumps attached to their surfaces. The two pressure plates 2 have a short pause, and the blade of the scraper 6 moves close to the front of the pressure plate 2 to scrape off the remaining lumps and reduce the indentations formed by the lumps on the subsequent bag openings, so as to improve the yield rate of fertilizer sealing. After reaching the upper edge of the pressure plate 2, it begins to lower until it is reset. At the same time, the vertical plate 5 drives the blocking component to limit the fertilizer bag from both sides, supporting the tilted fertilizer bag without scratching the fertilizer bag.

[0030] Refer to the attached Figure 1 and Figure 3 The blocking component includes multiple rubber rollers 7 vertically rotatably mounted on one side of the vertical plate 5, with gaps between adjacent rubber rollers 7. The upper edge of the vertical plate 5 is fixed with a receiving groove 8 with an opening facing upward. The rubber rollers 7 can support the tilted fertilizer bag from both sides while rising and falling with the vertical plate 5, and the rubber rollers 7 can rotate horizontally and will not scratch the fertilizer bag when idle. At this time, the receiving grooves 8 are used to catch the lumps falling from the blade of the shovel 6, separate the lumps, and prevent them from falling onto the surface of the feeding conveyor belt 1 and the rubber rollers 7.

[0031] Refer to the attached Figure 3 and Figure 4 The bottom wall of the receiving groove 8 is integrated with two symmetrical slopes 9. The connection between the two slopes 9 is raised upward in the middle of the receiving groove 8. After the agglomerates fall into the receiving groove 8, the slopes 9 are used to guide them toward both sides of the door frame 3, making it more convenient to discharge.

[0032] Refer to the attached Figure 3 and Figure 4 Both ends of the receiving groove 8 are fixed with guide plates 10 extending toward the outside of the feeding conveyor belt 1. There is an angle between the guide plate 10 and the vertical plate. The guide plate 10 further limits the agglomerates discharged from the slope 9, causing these agglomerates to deviate from the feeding conveyor belt 1 and fall.

[0033] Refer to the attached Figure 1 and Figure 2 On both sides of the vertical plate, protective nets 11 are fixed, which are staggered with the receiving grooves 8, and provide parallel protection from both sides to prevent staff from entering the door frame 3, and retain a large interval as the activity space for industrial robots.

[0034] Refer to the attached Figure 1, Figure 2 and Figure 5 , the driving element includes two transverse movement modules 12 symmetrically arranged above the feeding conveyor belt 1. The transverse movement module 12 can also be a linear module of the GTH5-L5-50-BC-50W model and is signal-connected to the control main board. Horizontally fixed to the output ends of the two transverse movement modules 12 are transverse and straight plates 13. One end of each of the two transverse and straight plates 13 passes through the vertical plate and is fixedly connected to the back of the pressing plate 2. The pressing plate 2 is supported by the transverse and straight plate 13. Once the transverse movement module 12 is started, the two pressing plates 2 can be horizontally moved closer to each other until they clamp the bag mouth, or the two pressing plates 2 can be driven to move away from each other to release the bag mouth.

[0035] Refer to the attached Figure 2 and Figure 3 , the length of the shovel blade 6 is less than the length of the receiving groove 8. Both corners of the blade of the shovel blade 6 have arcs. When impacting the caked mass, the chipping of the shovel blade 6 can be reduced. Especially, the caked mass shoveled off can be caught as much as possible by the receiving groove 8 that is longer than the shovel blade 6, further reducing the caked mass flying onto the feeding conveyor belt 1.

[0036] The working principle of the present utility model is as follows: During operation, after the fertilizer is bagged, it is placed on the belt of the feeding conveyor belt 1 and transported from one end to the other end. It stops briefly at the middle position. The driving element is started to push the two pressing plates 2 towards the middle to clamp the bag mouth. At the same time, the resistance wire is energized to heat the bag mouth to the set temperature, so that it is partially melted and bonded together. Then, the two pressing plates 2 are separated and retracted to a position away from the fertilizer bag within the door frame 3.

[0037] When cleaning the caked mass, the vertical movement module 4 is started to lift the vertical plate 5 and the shovel blade 6. During the short stop interval of the two pressing plates 2, the blade of the shovel blade 6 travels close to the front of the pressing plate 2 to scrape off the residual caked mass, reducing the indentation formed by the caked mass pressing on the subsequent bag mouth, so as to improve the qualified rate of fertilizer sealing. After reaching the upper edge of the pressing plate 2, it starts to lower until it is reset. At the same time, the fertilizer bag is limited from both sides to support the tilted fertilizer bag without scratching the fertilizer bag.

[0038] The above description is only the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model, unless otherwise specifically stated and limited, are implemented according to the conventional means in this field.
