Description

Technical Field

[0001] The present invention relates to the technical field of equipment for material conveying, and in particular to a material guiding device. Background Art

[0002] To prevent material from scattering, conveyor belts are equipped with guide plates when conveying materials. For example, when feeding materials on upper and lower conveyor belts that are perpendicular to each other, a guide plate is installed on the lower conveyor belt to reduce material scattering. A portion of the material conveyed by the upper conveyor belt hits the guide plate and slides along the guide plate to the conveyor belt below. Currently, metal plates are mostly used as guide plates. During use, it is found that materials will adhere to the surface of the guide plate. This is especially serious for materials with a certain humidity, such as tobacco. When conveying different batches of tobacco, the material adhered to the guide plate will cause mixing between the different batches of materials, affecting product quality. To reduce this problem, the guide plate needs to be cleaned regularly, but the cleaning process will affect production progress and has a short service life. The above problems need to be solved urgently. Summary of the Invention

[0034] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and corresponding drawings. In the description of the present invention, it should be noted that the term "or" is generally used in the sense of including "and / or" unless the content clearly indicates otherwise.

[0035] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or a magnetic connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be a connection between the two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances. In addition, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three or more, etc., unless otherwise clearly specified and limited.

[0036] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] In order to solve the problems existing in the prior art, an embodiment of the present application provides a material guiding device.

[0038] like Figure 1 、 Figure 2 and Figure 3 As shown, a material guiding device includes a material guiding plate 1, an anti-sticking structure 2, a bracket 3 and a surface treatment layer 4; the anti-sticking structure 2 is arranged on the material guiding plate 1 and includes a plurality of protrusions 21; the plurality of protrusions 21 protrude from the surface of the material guiding plate 1 and are evenly distributed, and the spacing M between adjacent protrusions 21 is 5-8 mm. If the spacing between adjacent protrusions 21 is too small, it is easy to cause the material to be stuck between the protrusions 21, and if it is too large, it will cause the material to contact the surface of the material guiding plate 1, increasing the adhesion amount; the bracket 3 is used to support the material guiding plate 1 so that the material guiding plate 1 forms an acute angle with the vertical direction; the surface treatment layer 4 is at least arranged on the surface of the anti-sticking structure 2 to improve the strength and / or hydrophobicity of the surface of the anti-sticking structure 2.

[0039] A material guiding device of the present invention is based on providing an anti-sticking structure 2 including multiple protrusions 21 on a material guide plate 1, and limiting the inclination angle of the material guide plate 1. When guiding the material, the material collides with the protrusions 21, which can reduce the contact area with the material, thereby reducing the amount of material adhesion, reducing the mixing between different materials, reducing the cleaning frequency, and improving production efficiency; based on providing a surface treatment layer on the surface of the anti-sticking structure, the service life or hydrophobicity of the material guiding device is improved.

[0040] In some preferred embodiments, Figure 1 As shown, the acute angle A formed by the guide plate 1 and the vertical direction is 30°≤A≤45°. In this angle range, the time for the material to slide can be reduced, thereby reducing the adhesion of the material. The larger receiving area can reduce the scattering of the material, that is, it is roughly perpendicular to the direction of the material, which can increase the probability of the material contacting and colliding with the top of the protrusion 21.

[0041] In some preferred embodiments, the angle A is 38°; at this angle, the material is most conducive to sliding down quickly, and the material is effectively received and the material scattering is reduced.

[0042] In some preferred embodiments, Figure 3 As shown, the protrusion 21 is a spherical table-shaped protrusion with a diameter D of 2-5 mm and a height H of 1-3 mm. Within this range, it is possible to ensure that the material contacts the protrusion 21, thereby reducing the contact area and achieving the best anti-sticking effect. If the diameter is too large, the surface contact area between the material and the protrusion 21 is large, and the anti-sticking effect is reduced. If the diameter is too small, the contact area between the material and the guide plate 1 is large, which also reduces the anti-sticking effect. In addition, if the diameter is too large, the service life is reduced. If the height is too large, the material is easily stuck between the protrusions 21, resulting in a reduction in the anti-sticking effect. If the height is too low, the service life is reduced. Specifically, the adhesion amount of the existing guide plate can be reduced from 200 g / m 2 h is reduced to less than or equal to 50g / m 2 ·h; cleaning cycle is reduced from 2 hours to 8 hours, and material mixing rate is reduced from 0.25% to 0.08%

[0043] Preferably, the protrusion 21 is a spherical table-shaped protrusion with a diameter D of 3 mm and a height H of 2 mm.

[0044] In some preferred embodiments, the distance M between adjacent protrusions 21 is 6 mm.

[0045] In some preferred embodiments, the guide plate 1 and the anti-sticking structure 2 are integrally formed and made of aviation aluminum.

[0046] In some preferred embodiments, the surface treatment layer 4 is a hard anodized layer, and the thickness of the hard anodized layer is 50-80 μm; and / or, the surface treatment layer 4 is a micro-arc oxidation strengthening layer, and the surface hardness of the micro-arc oxidation strengthening layer is ≥1200 HV; and / or, the surface treatment layer 4 is a hydrophobic treatment layer, and the contact angle θ of the hydrophobic treatment layer is ≥110°; based on the hard anodizing treatment of the anti-sticking structure 2 to improve the material hardness, thereby improving the service life, specifically, the hard anodizing treatment method can adopt the existing technology, which is not described in detail here; based on the micro-arc oxidation strengthening treatment (plasma electrolytic oxidation (PEO)) of the anti-sticking structure 2, the material hardness can be improved, thereby improving the service life, specifically, the micro-arc oxidation strengthening treatment method can adopt the existing technology, which is not described in detail here; based on the above surface strengthening treatment, the service life is increased from 3 months to greater than or equal to 18 months. Based on the hydrophobic treatment of the anti-sticking structure 2, the hydrophobicity of the anti-sticking structure 2 can be improved, which can further reduce the adhesion of the material; specifically, the method of hydrophobic treatment can refer to the existing technology, which is not described in detail here.

[0047] In some preferred embodiments, Figure 4 As shown, the guide plate 1 has a hollow cavity 11 inside; the protrusion 21 has an air outlet channel 211 connected to the cavity 11; the air outlet direction of the air outlet channel 211 includes the direction toward the surface of the guide plate 1; the cavity 11 is connected to the external pressure air source system; based on the setting of the cavity 11 and the air outlet channel 211, the material adhered to the surface of the guide plate 1 is blown away with high-pressure air, which can further reduce the amount of material residue, reduce the cleaning frequency, and reduce the material mixing rate.

[0048] Preferably, the air outlet of the air outlet channel 211 is oriented away from the protrusion 21 located directly in front; thereby, the blowing area is increased, the amount of adhesion is reduced, and after the air flow collides with the protrusion 21, it will deviate and flow in a direction roughly perpendicular to the surface of the guide plate 1, thereby reducing the moving speed of the material, reducing the collision with the guide plate 1 and the protrusion 21, increasing the service life, and reducing the amount of adhesion.

[0049] More preferably, Figure 8 As shown, two air outlets of the air outlet channel 211 are symmetrically provided, thereby blowing away the materials adhered to the surfaces of the material guide plates 1 on both sides and further improving the blowing effect.

[0050] Preferably, if Figure 2 As described, an exhaust port 12 is provided at the bottom of the guide plate 1; based on the setting of the exhaust port 13, the material entering the cavity 11 can be blown away to avoid material blockage and affect the exhaust of the exhaust channel 211, and the exhaust based on the exhaust port 12 can blow away the material accumulated under the guide plate 1, ensuring normal material discharge and avoiding material accumulation on the guide plate 1 to increase the adhesion amount.

[0051] Preferably, if Figure 8 As shown, the protrusion 21 is in the shape of a quadrangular pyramid; the edges extend in the horizontal and vertical directions, and the outlet of the air outlet channel 211 is arranged on the conical surface near the bottom of the guide plate 1; based on the protrusion 21 being in the shape of a quadrangular pyramid, the resistance of the material when sliding along the surface of the guide plate 1 can be reduced, and the residual amount can be reduced; further preferably, the angle between the conical surface of the quadrangular pyramid and the surface of the guide plate 1 is greater than or equal to 150°.

[0052] Further preferably, the air outlet of the air outlet channel 211 of the protrusion 21 faces the conical surface of the protrusion 21 set diagonally. On the one hand, it is convenient to blow away the accumulation on the conical surface of the protrusion 21. On the other hand, the dispersion through the conical surface can improve the air flow diffusion effect, thereby improving the blowing effect.

[0053] In some preferred embodiments, 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 to adjust the angle value of the angle A formed by the guide plate 1 and the vertical direction; based on the angle adjustment component 5, the angle of the guide plate 1 is adjusted, that is, different angles are formed with the material when receiving the material. As a result, the falling material can wash away the material remaining on the surface of the guide plate 1 through the change of the angle, thereby reducing the material residue and the amount of adhesion.

[0054] Optionally, the angle of the guide plate 1 can be changed by driving the rotating shaft connecting the guide plate 1 and the bracket 3 through a reciprocating motor or a rotating cylinder. At this time, the rotating shaft is fixedly connected to the guide plate 1 and rotationally connected to the bracket 3; the guide plate 1 can be driven to rotate by a linear drive member, such as a cylinder, and the telescopic end of the cylinder is against the surface opposite to the guide plate 1 and the anti-sticking structure 2.

[0055] Preferably, if Figure 6 As shown, the angle adjustment assembly 5 includes a driving member 51 and a driving block 52; the driving block 52 is provided with a slide groove 521 and is used to drive the guide plate 1 to rotate; the driving end of the driving member 51 is located in the slide groove 521 and can drive the driving block 52, and the driving end can slide in the slide groove 521; based on this, the guide plate 1 can be continuously adjusted within a preset angle range without using a reciprocating rotating device, that is, the rotating driving member 51 drives the driving block 52 to rotate, and at this time the driving end of the rotating driving member 51 is in the slide groove On one side of the groove 521, the angle A formed by the guide plate 1 is the smallest. As the driving block 52 rotates, it abuts and drives the guide plate 1 to rotate. Specifically, it abuts against the surface away from the anti-sticking structure 2, and the angle A gradually increases. When it increases to the maximum value, the extension direction of the slide groove 521 is perpendicular to the guide plate 1. At this time, under the downward pressure of the guide plate 1, the driving block 52 moves to the driving end of the driving member 51 on the other side of the slide groove 521, and the guide plate 1 returns to the position where the angle A is the smallest. In this way, the angle of the guide plate 1 is continuously adjusted.

[0056] Preferably, the driving member 51 is slow so that when the guide plate 1 rotates to the maximum angle A, the driving block 52 can move smoothly.

[0057] Preferably, if Figure 7 As shown, the driving block 52 is a long block structure with a slide groove 521 opened along the length direction; the driving end of the driving member 51 is non-circular, such as a square cross-section, and is clearance-matched with the slide groove 521.

[0058] Preferably, both ends of the driving block 52 in the length direction are arc surfaces, and the arc surfaces are used to contact the guide plate 1, thereby making it smoother for the driving block 52 to drive the guide plate 1 to rotate.

[0059] Preferably, if Figure 5 As shown, the bracket 3 includes a bracket 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 angle A of the guide plate 1 is minimum. Therefore, when the guide plate 1 falls to the position with the maximum angle A, the guide plate 1 vibrates based on the blocking of the blocking member 32, so as to achieve the effect of shaking off the residue and material on the surface of the guide plate 1, thereby further reducing the amount of material adhesion.

[0060] The embodiments of the present invention are described above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present invention, ordinary technicians in this field can also make many forms without departing from the scope of protection of the present invention and the claims, all of which are protected by the present invention.
