Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of material conveying equipment, and in particular to a material guiding device for an anti-adhesion belt conveyor. Background Technology
[0002] Conveyor belts use guide plates to prevent material spillage during material transport. For example, when conveyor belts are perpendicular to each other, a guide plate is placed on the lower conveyor belt to reduce spillage. Some of the material transported by the upper conveyor belt impacts the guide plate and slides down onto the lower conveyor belt. Currently, smooth metal plates are commonly used as guide plates. However, it has been found that material adheres to the surface of the guide plate, especially materials with a certain moisture content, such as tobacco. When transporting different batches of tobacco, the material adhering to the guide plate causes mixing between batches, affecting product quality. To reduce this problem, the guide plates need to be cleaned regularly, but the cleaning process affects production schedules. These problems urgently need to be solved. Utility Model Content

[0035] Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0036] To address the problems existing in the prior art, this application provides an anti-adhesion material guiding device for belt conveyors.
[0037] like Figure 1 and Figure 2 As shown, an anti-adhesion belt conveyor guiding device includes a guide plate 1, an anti-adhesion structure 2, and a support 3. The anti-adhesion structure 2 is disposed on the guide plate 1 and includes multiple protrusions 21. The multiple protrusions 21 protrude from the surface of the guide plate 1 and are evenly distributed. The support 3 is used to support the guide plate 1 and forms an angle A with the vertical direction, 30°≤A≤45°. Within this angle range, the time for material to slip can be reduced, thereby reducing material adhesion. It also has a large bearing area to reduce material scattering. That is, it is approximately perpendicular to the material direction, which can increase the probability of material contact and collision with the top of the protrusion 21.
[0038] This invention discloses an anti-adhesion material guiding device for belt conveyors. Based on an anti-adhesion structure 2 including multiple protrusions 21 on a guide plate 1, and limiting the tilt angle of the guide plate 1, the device reduces the contact area between the material and the protrusions 21 during material guidance. This reduces the amount of material adhering, decreases mixing between different materials, reduces cleaning frequency, and improves production efficiency. The anti-adhesion material guiding device of this invention can reduce the adhesion amount of existing guide plates from 200g / m³. 2 • h reduced to less than or equal to 50 g / m 2 • The cleaning cycle was reduced from 2 hours to 8 hours, and the material mixing rate was reduced from 0.25% to 0.08%.
[0039] In some preferred embodiments, such as Figure 2 and Figure 3 As shown, protrusion 21 is a frustum-shaped protrusion with a diameter D of 2-5 mm and a height H of 1-3 mm. The spacing between adjacent protrusions 21 is 5-8 mm. Within this range, the material can be guaranteed to contact the protrusion 21, thereby reducing the contact area and achieving the optimal anti-sticking effect. If the diameter is too large, the surface contact area between the material and the protrusion 21 will be large, reducing the anti-sticking effect. If the diameter is too small, the surface contact area between the material and the guide plate 1 will be large, also reducing the anti-sticking effect. In addition, a large diameter will reduce the service life. If the height is too large, the material is easy to get stuck between the protrusions 21, reducing the anti-sticking effect. If the height is too low, the service life will be reduced. If the spacing between adjacent protrusions 21 is too small, the material is easy to get stuck between the protrusions 21. If it is too large, the material will contact the surface of the guide plate 1, increasing the amount of adhesion.
[0040] Preferably, the protrusion 21 is a frustum-shaped protrusion with a diameter D of 3 mm, a height H of 2 mm, and a spacing M of 6 mm between adjacent protrusions 21.
[0041] In some preferred embodiments, the included angle A is 38°; at this angle, it is most advantageous for the material to slide down quickly, while ensuring effective catching of the material and reducing material spillage.
[0042] In some preferred embodiments, such as Figure 3 As shown, the guide plate 1 and the anti-stick structure 2 are integrally formed and are made of aviation aluminum. At least the surface of the anti-stick structure 2 is a surface treatment layer 4.
[0043] Preferably, the surface treatment layer 4 is a hard anodized layer with a thickness of 50-80 μm; and / or, the surface treatment layer 4 is a micro-arc oxidation strengthening layer with a surface hardness ≥1200 HV; and / or, the surface treatment layer 4 is a hydrophobic treatment layer with a contact angle θ ≥110°. Hard anodizing of the anti-stick structure 2 improves material hardness, thereby increasing its service life. Specifically, the hard anodizing treatment method can adopt existing technologies, which will not be elaborated here. Micro-arc oxidation strengthening treatment (plasma electrolytic oxidation (PEO)) of the anti-stick structure 2 can improve material hardness, thereby increasing its service life. Specifically, the micro-arc oxidation strengthening treatment method can adopt existing technologies, which will not be elaborated here. Based on the above surface strengthening treatments, the service life is increased from 3 months to greater than or equal to 18 months. Hydrophobic treatment of the anti-stick structure 2 improves its hydrophobicity, further reducing material adhesion. Specifically, the hydrophobic treatment method can refer to existing technologies, which will not be elaborated here.
[0044] In some preferred embodiments, such as Figure 4 As shown, the guide plate 1 has a hollow cavity 11 inside; the protrusion 21 has an air outlet channel 211 communicating with the cavity 11; the air outlet direction of the air outlet channel 211 includes the direction towards the surface of the guide plate 1; the cavity 11 is connected to an external pressure air source system; based on the setting of the cavity 11 and the air outlet channel 211, the material adhering to the surface of the guide plate 1 is blown away by high pressure air, which can further reduce the amount of material residue, reduce the cleaning frequency, and reduce the material mixing rate.
[0045] Preferably, the air outlet of the air outlet channel 211 is oriented away from the protrusion 21 located directly in front; thereby increasing the blowing area, reducing the amount of adhesion, and after the airflow collides with the protrusion 21, it will deviate and flow in a direction approximately perpendicular to the surface of the guide plate 1, thereby reducing the material movement speed, reducing the collision with the guide plate 1 and the protrusion 21, improving service life, and reducing the amount of adhesion.
[0046] More preferably, such as Figure 4 and Figure 8 As shown, the air outlet of the air outlet channel 211 is symmetrically arranged with two air outlets, thereby blowing away the material adhering to the surface of the guide plates 1 on both sides and further improving the blowing effect.
[0047] Preferably, such as Figure 2 As shown, the bottom of the guide plate 1 is provided with an exhaust port 12; based on the setting of the exhaust port 12, the material entering the cavity 11 can be blown away to avoid material blockage and affect the air outlet 211. Moreover, the exhaust from the exhaust port 12 can blow away the material accumulated below the guide plate 1, ensuring normal material feeding and preventing material from accumulating on the guide plate 1 and increasing the amount of adhesion.
[0048] Preferably, such as Figure 8 As shown, the protrusion 21 is a square pyramid shape; the edges extend in the horizontal and vertical directions, and the air outlet of the air outlet channel 211 is located on the conical surface near the bottom of the guide plate 1; based on the square pyramid shape of the protrusion 21, the resistance when the material slides down the surface of the guide plate 1 can be reduced, and the residual amount can be reduced; more preferably, the angle between the conical surface of the square pyramid and the surface of the guide plate 1 is greater than or equal to 150°.
[0049] In some preferred embodiments, such as Figure 1 and Figure 5 As shown, it also includes an angle adjustment component 5; the top of the guide plate 1 is rotatably connected to the bracket 3; the angle adjustment component 5 is used to drive the guide plate 1 to rotate, so as to adjust the angle A formed by the guide plate 1 and the vertical direction; based on the angle adjustment component 5 to adjust the angle of the guide plate 1, that is, to form different angles with the material when receiving the material, the material remaining on the surface of the guide plate 1 can be flushed off by the falling material through the angle change, thereby reducing material residue and reducing the amount of adhesion.
[0050] Optionally, the angle of the guide plate 1 can be changed by driving the rotating shaft connected to the bracket 3 through a reciprocating motor or a rotary cylinder. At this time, the rotating shaft is fixedly connected to the guide plate 1 and rotatably connected to the bracket 3. Alternatively, a linear drive, such as a cylinder, can be used to drive the guide plate 1 to rotate. At this time, the extension end of the cylinder rests against the surface of the guide plate 1 opposite to the anti-stick structure 2.
[0051] Preferably, such as Figure 1 , Figure 5 and Figure 6 As shown, the angle adjustment component 5 includes a drive member 51 and a drive block 52; the drive block 52 has a sliding groove 521 and is used to drive the guide plate 1 to rotate; the drive end of the drive member 51 is located in the sliding groove 521 and can drive the drive block 52, and the drive end can slide in the sliding groove 521; based on this, the guide plate 1 can be continuously adjusted within a preset angle range without the need for a reciprocating rotation device, that is, the drive member 51 drives the drive block 52 to rotate, and at this time the drive end of the drive member 51 slides within the sliding groove 521. On one side of the groove 521, the included angle A formed by the guide plate 1 is the smallest. As the drive block 52 rotates and abuts against and drives the guide plate 1 to rotate, specifically, it abuts against the surface away from the anti-stick structure 2. The included angle A gradually increases. When it increases to the maximum value, the extension direction of the groove 521 is perpendicular to the guide plate 1. At this time, under the downward pressure of the guide plate 1, the drive block 52 moves to the drive end of the drive member 51 on the other side of the groove 521, and the guide plate 1 returns to the position with the smallest included angle A. In this way, the angle of the guide plate 1 can be continuously adjusted.
[0052] Preferably, the drive component 51 is relatively slow, so that the drive block 52 can move smoothly when the guide plate 1 rotates to the maximum included angle A.
[0053] Preferably, such as Figure 7 As shown, the drive block 52 is a long strip block structure with a groove 521 along its length; the drive end of the drive member 51 is non-circular, such as having a square cross-section, and is clearance-fitted with the groove 521.
[0054] Preferably, the two ends of the drive block 52 in the length direction are arc surfaces, which are used to contact the guide plate 1, thereby making the drive block 52 drive the guide plate 1 to rotate more smoothly.
[0055] Preferably, such as Figure 5 As shown, the support 3 includes a support body 31 and a blocking member 32. The blocking member 32 blocks the rotation path of the guide plate 1, and when the guide plate 1 is in contact with the blocking member 32, the included angle A of the guide plate 1 is the smallest. Therefore, when the guide plate 1 falls from the position with the largest included angle A, the blocking member 32 causes the guide plate 1 to vibrate, thereby shaking off the residual material on the surface of the guide plate 1 and further reducing the amount of material adhering.
[0056] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of the present invention.
