Description

Technical Field

[0001] The invention relates to the technical field of ground double-roller feeders, and in particular to a ground double-roller feeder with an anti-stuck structure. Background Art

[0002] The core of the ground twin-shaft feeder is two parallel shafts, which are usually made of high-strength metals such as carbon steel or alloy steel to ensure sufficient strength and wear resistance. The shafts are equipped with blades or spirals, and their shapes and sizes are designed according to the specific requirements of feeding. The blades can be continuous spiral shapes or intermittent paddle shapes. Through the synergistic effect of the twin shafts, the flow speed and flow rate of the material can be effectively controlled to achieve uniform feeding, which is very important for ensuring the efficient and stable operation of subsequent processing equipment. Uniform raw material feeding can improve the quality of the material and production efficiency. It can handle a variety of materials with different characteristics, including granular, powdery, blocky, and viscous or poorly fluid materials. By adjusting the speed of the twin shafts, blade shape and other parameters, it can adapt to the feeding requirements of different materials.

[0003] After the equipment has been running for a long time, there will be material residue on the double rollers. If it is not cleaned regularly, these residual materials will gradually accumulate, changing the effective space between the double rollers and the material flow channel. Over time, these materials will harden and agglomerate, affecting the normal rotation of the double rollers and eventually causing material jamming. Summary of the invention

[0004] In view of the deficiencies of the prior art, the technical solution adopted by the present invention to solve the technical problems is: a ground double-roller feeder with an anti-stuck structure described in the present invention comprises:

[0005] A machine body, wherein a transmission component is fixedly connected to the side of the machine body, and a conveying component is fixedly connected to the bottom of the machine body;

[0008] Preferably, the anti-stuck mechanism includes an auxiliary roller, both ends of the auxiliary roller are rotatably connected to the inner side of the mixing shell, the inner side of the auxiliary roller is slidably connected with a sliding rod, one end of the sliding rod away from the auxiliary roller is fixedly connected with an auxiliary block, and the inner side of the auxiliary block is slidably connected with a contact component, a first spring is sleeved on the sliding rod, one end of the first spring is fixedly connected to the inner side of the auxiliary roller, and the other end of the first spring is fixedly connected to the auxiliary block; when the crushing roller is driven to rotate in the mixing shell through the output end of the transmission component, the crushing roller and the auxiliary roller are contacted and rotated, and at the same time, an auxiliary spring is arranged on the side of the auxiliary roller The auxiliary block can push out the large particles stuck in the crushing roller, so as to avoid the large particles sticking to the crushing roller when discharging, thereby reducing the gap between the two rollers. At the same time, the crushing roller moves in contact with the contact component when rotating, so that the contact component scrapes the side of the crushing roller. When the material enters between the two rollers, the side of the auxiliary roller can prevent the material from over-accumulating in a certain area, so that the material is distributed more evenly between the two rollers. For materials with uneven particle sizes, the auxiliary roller can use the auxiliary block on its side to disperse the large particles to avoid the phenomenon of large particles concentrating in one place and causing material jam;

[0011] Preferably, the conveying component includes a connecting frame, a control motor is fixedly connected to the side of the connecting frame, a conveyor belt is arranged on the inner side of the connecting frame, a cleaning mechanism is fixedly connected to the side of the connecting frame, and the cleaning mechanism is arranged below the conveyor belt; when the material in the mixing shell is discharged through the discharge port, the conveyor belt is driven to rotate by operating the control motor, so that the conveyor belt conveys and feeds the material, but since the conveyor belt is in contact with the material for a long time, a large number of material particles are prevented from being stuck on the conveyor belt, which makes it difficult to fall naturally. By arranging a cleaning mechanism below the conveyor belt, the cleaning mechanism can clean the side of the conveyor belt when the conveyor belt is in the conveying work, so as to avoid a large amount of material impurities remaining on the conveyor belt when the conveyor belt is in the conveying work for a long time;

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. The present invention provides an anti-stuck mechanism. When the crushing roller is driven to rotate in the mixing shell through the output end of the transmission component, the crushing roller and the auxiliary roller are contacted and rotated. At the same time, an auxiliary block is provided on the side of the auxiliary roller, so that the auxiliary block can push out the large particles stuck in the crushing roller, so as to avoid the large particles from adhering to the crushing roller and solidifying on the crushing roller during discharge, thereby causing the gap between the two rollers to become smaller.

For materials with uneven particle sizes, the auxiliary roller can use the auxiliary blocks on its side to disperse the large particles, so as to avoid the phenomenon of large particles concentrating in one place and causing material jamming.

[0016] 2. The present invention provides a contact component. If the material has a tendency to stick or pile up, the auxiliary roller can disperse the material to prevent it from forming large blocks and getting stuck. The auxiliary roller can also help push the crushed material out of the gap between the double rollers in time when the double rollers are crushing the material, so that the material can pass through the feeder smoothly and keep the material flow between the double rollers unobstructed. When the auxiliary block and the crushing roller move against each other, the large particle material stuck on the crushing roller is ejected by the auxiliary block. By providing a triangular plate on the inner side of the auxiliary block, the triangular end of the triangular plate can move against the side of the crushing roller. At the same time, by providing bent plates on both sides of the triangular plate, when the crushing roller and the auxiliary block are squeezed, the triangular plate can drive the bent plate to clean the inner side of the crushing roller.

[0017] 3. The present invention sets a spray component. When the double rollers rotate in the mixing shell, extrusion rods are set at both ends of the double rollers. When the double rollers rotate, the double rollers drive the extrusion rods and the extrusion blocks to be extruded, so that the extrusion blocks drive the extrusion plates to move in the water tank through the extrusion shafts, so that the water in the water tank is sprayed around the machine body through the spray heads to reduce dust, thereby preventing a large amount of dust from being generated around the machine body and floating around the device during the operation of the double roller feeder.

[0018] 4. The present invention provides a cleaning mechanism. When the conveyor belt is conveying, the conveyor belt and the scraper assembly move against each other, so that the scraper assembly cleans the side of the conveyor belt. At the same time, when the extrusion force between the scraper assembly and the material stuck in the conveyor belt is greater than the tensile force of the fourth spring, the scraper assembly moves downward through the moving rod, and at the same time, the fourth spring is used for buffering, so as to avoid excessive extrusion force between the scraper assembly and the conveyor belt, which will cause extrusion damage to the conveyor belt.

For blocky or uneven materials, this process can disperse the materials and prepare for subsequent stable feeding. At the same time, when the particle size of the material is uneven and there are too large particles, these large particles may be stuck on the double rollers, thereby causing material jamming;

[0035] The anti-stuck mechanism 24 includes an auxiliary roller 241, both ends of which are rotatably connected to the inner side of the mixing shell 21, a sliding rod 242 is slidably connected to the inner side of the auxiliary roller 241, an end of the sliding rod 242 away from the auxiliary roller 241 is fixedly connected to an auxiliary block 243, and a contact assembly 245 is slidably connected to the inner side of the auxiliary block 243, a first spring 244 is sleeved on the sliding rod 242, one end of the first spring 244 is fixedly connected to the inner side of the auxiliary roller 241, and the other end of the first spring 244 is fixedly connected to the auxiliary block 243; when the crushing roller 22 is driven to rotate in the mixing shell 21 through the output end of the transmission component 3, the crushing roller 22 and the auxiliary roller 241 are contacted and rotated, and at the same time, the auxiliary roller 241 is An auxiliary block 243 is arranged on the side, so that the auxiliary block 243 can push out the large particles stuck in the crushing roller 22, so as to prevent the large particles from adhering and solidifying on the crushing roller 22 when discharging, thereby reducing the gap between the two rollers. At the same time, when the crushing roller 22 rotates, it contacts and moves with the contact component 245, so that the contact component 245 scrapes the side of the crushing roller 22. When the material enters between the two rollers, the side of the auxiliary roller 241 can prevent the material from excessively piling up in a certain area, so that the material is distributed more evenly between the two rollers. For materials with uneven particle sizes, the auxiliary roller 241 can use the auxiliary block 243 on its side to disperse the large particles, so as to avoid the phenomenon of large particles concentrating in one place and causing the material to get stuck.

[0036] The contact assembly 245 includes a connecting rod 2453, one end of which is slidably connected to the inner side of the auxiliary block 243, the other end of the connecting rod 2453 is fixedly connected to a triangular plate 2451, both sides of the triangular plate 2451 are fixedly connected to a bent plate 2452, and a second spring 2454 is sleeved on the connecting rod 2453, one end of the second spring 2454 is fixedly connected to the inner side of the auxiliary block 243, and the other end of the second spring 2454 is fixedly connected to the side of the triangular plate 2451; if the material has a tendency to stick or accumulate, the auxiliary roller 241 can disperse the material to prevent it from forming large blocks and getting stuck. The auxiliary roller 241 can also help push the crushed material out of the gap between the two rollers in time when the two rollers are crushing the material, so that the material can pass through the feeder smoothly and keep the material flow between the two rollers unobstructed. When the auxiliary block 243 and the crushing roller 22 move against each other, the auxiliary block 243 will push the material stuck in the crushing roller 22. When the large particles on the roller 22 are ejected, a triangular plate 2451 is provided on the inner side of the auxiliary block 243, so that the triangular end of the triangular plate 2451 can move against the side of the crushing roller 22, and at the same time, bent plates 2452 are provided on both sides of the triangular plate 2451, so that when the crushing roller 22 and the auxiliary block 243 are squeezed, the triangular plate 2451 can drive the bent plates 2452 to clean the inner side of the crushing roller 22. At the same time, when the triangular plate 2451 and the crushing roller 22 move against each other, when the contact extrusion force between the triangular plate 2451 and the inner side of the crushing roller 22 is greater than the tensile force of the second spring 2454, the triangular plate 2451 slides on the inner side of the auxiliary block 243 through the connecting rod 2453, and at the same time, the second spring 2454 works as a buffer, so that the extrusion force between the triangular plate 2451 and the crushing roller 22 is too large, which will cause friction damage to the side of the crushing roller 22.

[0037] The spraying component 5 includes a water tank 51, the side of the water tank 51 is fixedly connected to the mixing shell 21, an extrusion shaft 52 is inserted into the inner side of the water tank 51, the extrusion shaft 52 penetrates the side of the water tank 51 and the inner wall of the mixing shell 21, one end of the extrusion shaft 52 is fixedly connected to an extrusion block 53, the other end of the extrusion shaft 52 is fixedly connected to an extrusion plate 54, the side of the extrusion plate 54 is slidably connected to the inner side of the water tank 51, a third spring 55 is sleeved on the extrusion shaft 52, one end of the third spring 55 is fixedly connected to the extrusion plate 54, and the other end of the third spring 55 is fixedly connected to the inner wall of the water tank 51, the water A spray head 56 is fixedly connected to the top of the box 51; when the double rollers rotate in the mixing shell 21, the extrusion rods 23 are arranged at both ends of the double rollers. When the double rollers rotate, the extrusion rods 23 and the extrusion blocks 53 are driven by the double rollers to squeeze, so that the extrusion blocks 53 drive the extrusion plates 54 to move in the water tank 51 through the extrusion shafts 52, so that the water in the water tank 51 is sprayed around the machine body 1 through the spray heads 56 to reduce dust, so that during the operation of the double roller feeder, a large amount of dust is prevented from being generated around the machine body 1 and then floating around the device;

[0038] Example 2, using Figure 7-Figure 9 A ground double-roller feeder with an anti-stuck structure of the present invention is described as follows;

[0039] like Figure 7-Figure 9 It is shown that a ground double-roller feeder with an anti-stuck structure of the present invention is based on the first embodiment;

[0040] The conveying component 4 includes a connecting frame 41, a control motor 42 is fixedly connected to the side of the connecting frame 41, a conveyor belt 43 is arranged on the inner side of the connecting frame 41, and a cleaning mechanism 44 is fixedly connected to the side of the connecting frame 41, and the cleaning mechanism 44 is arranged below the conveyor belt 43; when the material in the mixing shell 21 is discharged through the discharge port, the conveyor belt 43 is driven to rotate by operating the control motor 42, so that the conveyor belt 43 conveys and feeds the material, but because the conveyor belt 43 is in contact with the material for a long time, it is avoided that a large number of material particles are stuck on the conveyor belt 43, which is difficult to fall naturally. By arranging the cleaning mechanism 44 below the conveyor belt 43, when the conveyor belt 43 is in the conveying work, the cleaning mechanism 44 can clean the side of the conveyor belt 43, so as to avoid a large number of material impurities remaining on the conveyor belt 43 when the conveyor belt 43 is in the conveying work for a long time;

[0041] The cleaning mechanism 44 includes a cleaning frame 441, both sides of the cleaning frame 441 are fixedly connected to the connecting frame 41, a moving rod 443 is fixedly connected to the inner side of the cleaning frame 441, a scraper assembly 442 is slidably connected to the moving rod 443, a fourth spring 444 is sleeved on the moving rod 443, the bottom of the fourth spring 444 is fixedly connected to the slider 4424, and the bottom of the fourth spring 444 is fixedly connected to the inner side of the cleaning frame 441. When the conveyor belt 43 is conveying, the conveyor belt 43 and the scraper assembly 442 are moved against each other, so that the scraper assembly 442 cleans the side of the conveyor belt 43. At the same time, when the extrusion force of the scraper assembly 442 and the material stuck between the conveyor belt 43 is greater than the tensile force of the fourth spring 444, the scraper assembly 442 moves downward through the moving rod 443, and at the same time, the fourth spring 444 is used for buffering, so as to avoid excessive extrusion force between the scraper assembly 442 and the conveyor belt 43, thereby causing extrusion damage to the conveyor belt 43.

[0042] The scraper assembly 442 includes a rotating shaft 4421, both ends of the rotating shaft 4421 are rotatably connected to a slider 4424, the inner side of the slider 4424 is slidably connected to the side of the moving rod 443, and both sides of the rotating shaft 4421 are fixedly connected to a scraper 4423, the side of the scraper 4423 away from the rotating shaft 4421 is in contact with the side of the conveyor belt 43, and the side of the rotating shaft 4421 away from the scraper 4423 is fixedly connected to a square plate 4422; when the conveyor belt 43 and the square plate 4422 are in contact, the conveyor belt 43 and the square plate 4422 are in contact. When the conveyor belt 43 is in contact and moving, the scraper 4423 is squeezed by the conveyor belt 43, so that the scraper 4423 cleans and scrapes the side of the conveyor belt 43, thereby preventing a large amount of material dust from being attached to the surface of the conveyor belt 43 when the conveyor belt 43 is in conveying work. At the same time, by providing a square plate 4422 on the other side of the rotating shaft 4421, when the conveyor belt 43 is in contact and rotating with the rotating shaft 4421, the square plate 4422 can push out the impurities stuck in the conveyor belt 43;

[0043] The specific workflow is as follows:

[0044] When working, by putting materials into the mixing component 2, the mixing component 2 breaks up the aggregated materials, making the discharged materials more uniform and loose, which is convenient for subsequent equipment to receive and process. At the same time, when the mixing component 2 is working, the spray component 5 can spray and reduce dust around the double-axis feeder, and the materials passing through the mixing component 2 can be transported by the conveying component 4;

[0045] When the material enters the mixing housing 21, the transmission component 3 is opened, and the crushing roller 22 is driven to rotate in the mixing housing 21 through the output end of the transmission component 3. The blades on the shaft move with the rotation of the shaft to stir and preliminarily push the material. For blocky or uneven materials, this process can disperse the materials and prepare for subsequent stable feeding. At the same time, when the particle size of the material is uneven and there are too large particles, these large particles may be stuck on the double rollers, resulting in material jamming;

[0046] When the crushing roller 22 is driven to rotate in the mixing housing 21 through the output end of the transmission component 3, the crushing roller 22 and the auxiliary roller 241 are contacted and rotated. At the same time, an auxiliary block 243 is provided on the side of the auxiliary roller 241, so that the auxiliary block 243 can push out the large particles stuck in the crushing roller 22, so as to avoid the large particles from adhering to the crushing roller 22 when discharging, thereby causing the gap between the two rollers to become smaller. At the same time, the crushing roller 22 is moved in contact with the contact component 245 when rotating, so that the contact component 245 scrapes the side of the crushing roller 22. When the material enters between the two rollers, the side of the auxiliary roller 241 can prevent the material from being excessively accumulated in a certain area, so that the material is distributed more evenly between the two rollers. For materials with uneven particle sizes, the auxiliary roller 241 can use the auxiliary block 243 on its side to disperse the large particles to avoid the phenomenon of large particles concentrating in one place and causing material jamming.

[0047] If the material has a tendency to stick or pile up, the auxiliary roller 241 can disperse the material to prevent it from forming large blocks and getting stuck. The auxiliary roller 241 can also help push the crushed material out of the gap between the two rollers in time when the two rollers are crushing the material, so that the material can pass through the feeder smoothly and keep the material flow between the two rollers unobstructed. When the auxiliary block 243 and the crushing roller 22 move against each other, the large particles stuck on the crushing roller 22 are ejected by the auxiliary block 243. By providing a triangular plate 2451 on the inner side of the auxiliary block 243, the triangular end of the triangular plate 2451 moves against the side of the crushing roller 22. At the same time, by Bending plates 2452 are provided on both sides of 51, so that when the crushing roller 22 and the auxiliary block 243 are squeezed, the triangular plate 2451 can drive the bending plate 2452 to clean the inner side of the crushing roller 22. At the same time, when the triangular plate 2451 and the crushing roller 22 move against each other, when the contact squeezing force between the triangular plate 2451 and the inner side of the crushing roller 22 is greater than the tensile force of the second spring 2454, the triangular plate 2451 slides in the inner side of the auxiliary block 243 through the connecting rod 2453, and at the same time, through the buffering work of the second spring 2454, the squeezing force between the triangular plate 2451 and the crushing roller 22 is too large, which will cause friction damage to the side of the crushing roller 22.

[0048] When the double rollers rotate in the mixing housing 21, squeezing rods 23 are provided at both ends of the double rollers. When the double rollers rotate, the double rollers drive the squeezing rods 23 and the squeezing blocks 53 to squeeze, so that the squeezing blocks 53 drive the squeezing plates 54 to move in the water tank 51 through the squeezing shafts 52, so that the water in the water tank 51 is sprayed around the machine body 1 through the spray heads 56 to reduce dust, so that during the operation of the double roller feeder, a large amount of dust is prevented from being generated around the machine body 1 and then floating around the device;

[0049] When the material in the mixing housing 21 is discharged through the discharge port, the conveyor belt 43 is driven to rotate by operating the control motor 42, so that the conveyor belt 43 can convey and feed the material. However, since the conveyor belt 43 is in contact with the material for a long time, a large number of material particles are prevented from being stuck on the conveyor belt 43, which makes it difficult for them to fall naturally. By arranging a cleaning mechanism 44 under the conveyor belt 43, the cleaning mechanism 44 can clean the side of the conveyor belt 43 when the conveyor belt 43 is conveying, so as to avoid a large number of material impurities remaining on the conveyor belt 43 when the conveyor belt 43 is conveying for a long time.

[0050] When the conveyor belt 43 is conveying, the conveyor belt 43 and the scraper assembly 442 move against each other, so that the scraper assembly 442 cleans the side of the conveyor belt 43. At the same time, when the extrusion force of the scraper assembly 442 and the material stuck between the conveyor belt 43 is greater than the tensile force of the fourth spring 444, the scraper assembly 442 moves downward through the moving rod 443, and at the same time, the fourth spring 444 buffers, thereby preventing the extrusion force between the scraper assembly 442 and the conveyor belt 43 from being too large, thereby causing extrusion damage to the conveyor belt 43.

[0051] When the conveyor belt 43 and the square plate 4422 are in contact and moving, the scraper 4423 is squeezed by the conveyor belt 43, so that the scraper 4423 cleans and scratches the side of the conveyor belt 43, thereby avoiding a large amount of material dust attached to the surface of the conveyor belt 43 when the conveyor belt 43 is conveying. At the same time, by providing a square plate 4422 on the other side of the rotating shaft 4421, when the conveyor belt 43 and the rotating shaft 4421 are in contact and rotating, the square plate 4422 can eject impurities stuck in the conveyor belt 43.
