[0044] As mentioned above, the existing chute base plate of the conveying chute is mostly arranged in a smooth plane, and the goods conveyed on the chute are in contact with the plate surface of the chute base plate. When the environment is relatively humid, the chute base plate is easy to adsorb the goods with outer packaging of foam boxes or plastic bags and other materials during the sliding process of the goods, which causes difficulty in the sliding of the goods, and even blocks the sliding of the goods.

[0045] In view of this, the present application provides a conveying chute.

[0046] In the embodiment of the present application, as shown in Figure 1 and Figure 2 The conveying chute comprises a chute base plate 10 and a plurality of protrusions 20, wherein the plurality of protrusions 20 are arranged on the chute base plate 10, each protrusion 20 is formed with a guide surface 211 located at the middle part 210 thereof, and the plurality of guide surfaces 211 extend in the same direction, and the guide surface 211 is used for guiding the sliding of the goods.

[0047] The chute base plate 10 is a base plate used for bearing the goods in the conveying chute, and the plurality of protrusions 20 are located on the contact surface of the chute base plate 10 for bearing the goods, wherein the contact surface part of the chute base plate 10 can be provided with the plurality of protrusions 20, or the entire contact surface of the chute base plate 10 can be provided with the plurality of protrusions 20. The chute base plate 10 can be a flat plate or a curved plate, and the shape of the chute base plate 10 can be a square plate or a special-shaped plate, and the shape structure of the chute base plate 10 is not specifically limited.

[0048] It should be noted that the chute base plate 10 of the present application can be applied to a chute of a self-weight sliding type at a certain angle with the horizontal plane, or a chute parallel to the horizontal plane, or a combined chute comprising the above two chute types.

[0049] The height of the protrusion 20 continuously increases from the part connected with the chute base plate 10 to the middle part 210, and the middle part 210 is formed with a guide surface 211 used for contacting the goods away from the side of the chute base plate 10. The plurality of guide surfaces 211 extend in the same direction, that is, the guide directions of the plurality of guide surfaces are consistent, so that the goods on the chute can slide quickly and be oriented.

[0050] The technical scheme of the present application adopts the plurality of protrusions 20 arranged on the chute base plate 10, and each protrusion 20 is formed with a guide surface 211 used for guiding the sliding of the goods, so that the goods on the chute have a spacing with the chute base plate 10, which prevents the goods from being adsorbed on the chute base plate 10 in a humid environment, and makes the sliding of the goods more smooth.

[0051] In an embodiment, please refer to Figure 3The protrusion 20 further comprises a first guide surface 221 and a second guide surface 222. The first guide surface 221 is located on opposite sides of the guide surface 211, and each of the first guide surfaces 221 is connected to the guide surface 211. The second guide surface 222 is located on opposite ends of the guide surface 211 in the guide direction, and each of the second guide surfaces 222 is connected to the guide surface 211. The same side of each of the second guide surfaces 222 is connected to the two first guide surfaces 221.

[0052] It should be noted that the two first guide surfaces 221 and the two second guide surfaces 222 are the outer surfaces of the four support portions 220 for supporting the middle portion 210. The two support portions 220 are located at opposite ends of the middle portion 210, and the other two support portions 220 are located at opposite sides of the middle portion 210. Each of the four support portions 220 is connected to the middle portion 210, and each of the support portions 220 at the two ends of the middle portion 210 is connected to the support portions 220 at the two sides of the middle portion 210. Correspondingly, the two first guide surfaces 221 are the outer surfaces of the support portions 220 at the opposite sides of the middle portion 210, and the two second guide surfaces 222 are the outer surfaces of the support portions 220 at the opposite ends of the middle portion 210.

[0053] Without being limited to the embodiment, the protrusion 20 can also comprise only the support portions 220 at the two ends of the middle portion 210. Correspondingly, the protrusion 20 comprises the second guide surfaces 222 on the surfaces of the support portions 220 at the two ends of the middle portion 210. The protrusion 20 can also comprise only the support portions 220 at the two sides of the middle portion 210. Correspondingly, the protrusion 20 comprises the first guide surfaces 221 on the surfaces of the support portions 220 at the two sides of the middle portion 210.

[0054] In an embodiment, as shown in Figure 3 and Figure 4 , the protrusion 20 further comprises a transition surface 230. The guide surface 211 is connected to the first guide surface 221 through the transition surface 230, and there is a height difference between the first guide surface 221 and the guide surface 211.

[0055] Specifically, there is a height difference between the guide surface 211 and the first guide surface 221, and the guide surface 211 is used for guiding the goods to slide downward. That is, the height of the first guide surface 221 relative to the chute base plate 10 is less than the height of the guide surface 211 relative to the chute base plate 10. In this way, there is a space between the first guide surface 221 and the goods for the gas to flow, preventing the goods from being adsorbed on the chute base plate 10 during the sliding process.

[0056] In an embodiment, as shown in Figure 5The first guide surface 221 has a first profile line 2211 intersecting the plate surface of the chute base plate 10 and a second profile line 2212 intersecting the guide surface 211. A plane is perpendicular to a line segment in the length direction of the guide surface 211, and the plane passes through the midpoint of the line segment. The plane intersects the first profile line 2211 and the second profile line 2212 to form a first intersection point 2213 and a second intersection point 2214, respectively. The line connecting the first intersection point 2213 and the second intersection point 2214 forms a first included angle 240 with the plate surface of the chute base plate 10. The angle range of the first included angle 240 is set to 10 degrees to 15 degrees.

[0057] It should be noted that the plane and the line segment described in the embodiment are only auxiliary concepts for describing the embodiment, and are not specific structural features in the embodiment. The line connecting the first intersection point 2213 and the second intersection point 2214 forms a first included angle 240 with the plate surface of the chute base plate 10. Considering that the support portions 220 on the opposite sides of the middle portion 210 should have a better supporting effect on the middle portion 210, the angle of the first included angle 240 should not be too small, and the range of the first included angle 240 is set to be greater than or equal to 10 degrees. It is also considered that the support portions 220 on the opposite sides of the middle portion 210 should have sufficient space with the goods to prevent adsorption, so the angle of the first included angle 240 should not be too large, and the range of the first included angle 240 is set to be less than or equal to 15 degrees.

[0058] In an embodiment, referring to Figure 6 The second guide surface 222 has a third profile line 2221 intersecting the plate surface of the chute base plate 10 and a fourth profile line 2222 intersecting the guide surface 211. A plane is perpendicular to a line segment in the width direction of the guide surface 211, and the plane passes through the midpoint of the line segment. The plane intersects the third profile line 2221 and the fourth profile line 2222 to form a third intersection point 2223 and a fourth intersection point 2224, respectively. The length of the vertical projection of the line connecting the third intersection point 2223 and the fourth intersection point 2224 on the chute base plate 10 is less than the length of the vertical projection of the line connecting the first intersection point 2213 and the second intersection point 2214 on the chute base plate 10.

[0059] It should be noted that the plane and the line segment described in the embodiment are only auxiliary concepts for describing the embodiment, and are not specific structural features in the embodiment. The length of the vertical projection of the line connecting the third intersection point 2223 and the fourth intersection point 2224 on the chute base plate 10 is less than the length of the vertical projection of the line connecting the first intersection point 2213 and the second intersection point 2214 on the chute base plate 10, so that the support portions 220 on the two sides of the middle portion 210 have a better supporting effect than the support portions 220 at the two ends of the middle portion 210.

[0060] In an embodiment, referring to Figure 3 , the protrusions 20 are arranged in a diamond shape, and any two adjacent edges of the protrusions 20 are equal in length, wherein the inner angle of the guiding direction of the guiding surface 211 is smaller than the inner angle perpendicular to the guiding direction of the guiding surface 211. On the basis of the slide base plate 10 being provided with a plurality of support portions 220, the area of the support portions 220 is minimized, so that the stability of the structure of the protrusions 20 is enhanced, and the material required for forming the protrusions 20 is reduced, and the cost is reduced.

[0061] In an embodiment, referring to Figure 3 , the guiding surface 211 is arranged along the diagonal direction of the protrusions 20. Specifically, according to the above embodiment, the guiding surface 211 is arranged in a diamond shape, and thus the guiding surface 211 has two diagonals, and the guiding surface 211 is arranged along one of the diagonals. In this way, the guiding direction of the second guiding surface 222 is arranged in alignment with the guiding direction of the guiding surface 211.

[0062] When the protrusions 20 are in a diamond shape, the protrusions 20 have a plurality of corners, which can be arranged in a sharp corner shape or a rounded corner shape. It should be noted that when the plurality of corners are arranged in a rounded corner shape, the stress received by the goods when the goods collide with the protrusions 20 can be dispersed, so that the goods are prevented from being damaged or cracked due to collision with the corners of the protrusions 20.

[0063] In an embodiment, referring to Figure 1 and Figure 7 , the plurality of protrusions 20 are arranged in an array on the slide base plate 10.

[0064] Specifically, the plurality of protrusions 20 are arranged in a substantially rectangular array, so that the supporting force received by the goods when the goods slide is stable, and the sliding direction of the goods is ensured to be relatively stable.

[0065] In an embodiment, referring to Figure 7 , a direction perpendicular to the extension direction of the guiding surface 211 is defined as a first direction, and any two adjacent rows of protrusions 20 in the first direction are arranged in a staggered manner in the extension direction of the guiding surface 211.

[0066] Specifically, according to the above embodiment, the plurality of protrusions 20 are arranged in an array on the slide base plate 10, and thus the slide base plate 10 has a plurality of rows of protrusions 20, and any two adjacent rows of protrusions 20 in the first direction are arranged in a staggered manner in the extension direction of the guiding surface 211. Specifically, any one protrusion 20 in one row is located between two adjacent protrusions 20 in another row, so that the distance between any two adjacent protrusions 20 is equal, and the goods slide more stably.

[0067] In an embodiment, referring to Figure 8 , two adjacent said protrusions 20 have a first preset interval H1, and the H1 satisfies 0.5mm≤H1≤7mm.

[0068] Specifically, the first preset interval between two adjacent protrusions 20 is the distance between the first guide surfaces 221 of two adjacent protrusions 20. It is considered that when the first preset interval is too large, the force interval of the goods during transmission is large, and under the condition that the chute area is constant, the first preset interval is too large, which will reduce the number of protrusions 20 and the force point of the goods, and the possibility of deformation of the goods due to uneven force will increase. Therefore, the first preset interval H1≤7mm is set. It is also considered that when the first preset interval is too small, the air permeability of the chute base plate 10 is reduced, so the first preset interval is set to be ≥0.5mm.

[0069] In an embodiment, referring to Figure 8 , two adjacent said guide surfaces 211 have a second preset interval H2, and the H2 satisfies 3mm≤H2≤15mm.

[0070] Specifically, the second preset interval between two adjacent guide surfaces 211 is the distance between the two closest force points of the goods during sliding on the chute base plate 10. It is considered that when the second preset interval is too large, the force interval of the goods during transmission is large, and under the condition that the chute area is constant, the force point of the goods will be reduced, and the possibility of deformation of the goods due to uneven force will increase. Therefore, the first preset interval H2≤15mm is set. It is also considered that when the second preset interval is too small, the air permeability of the chute base plate 10 is reduced, so the second preset interval is set to be ≥3mm.

[0071] Further, referring to Figure 9 , the guide surface 211 has a length L1, and the L1 satisfies 3mm≤L1≤20mm.

[0072] It should be noted that the guide surface 211 has a length and a width. It is considered that in order to ensure that the guide surface 211 has a good guiding effect, the length of the guide surface 211 should be significantly greater than the width of the guide surface 211. Therefore, the width L1 of the guide surface 211 is set to be ≥3mm. It is considered that the guide surface 211 is formed on the protrusion 20, and the length of the guide surface 211 should be less than the length of the protrusion 20. Therefore, the length L1 of the guide surface 211 is set to be ≤20mm.

[0073] In an embodiment, referring to Figure 10The guide surface 211 has a height H3 relative to the chute base plate 10, and the H3 satisfies 0.5mm≤H3≤10mm.

[0074] Specifically, considering that the height of the guide surface 211 relative to the chute base plate 10 is too small, the goods sliding on the chute base plate 10 will generate a certain deformation and still contact the chute base plate 10, so H3≥0.5mm is set. Also considering that the height of the guide surface 211 relative to the chute base plate 10 is too large, it will cause poor stability of the protrusion 20, and it is very difficult to manufacture a mold for producing the conveying chute, which increases the difficulty of producing the conveying chute, so H3≤10mm is set.

[0075] In an embodiment, referring to Figure 1 The conveying chute comprises a rubber coating layer 110 and a glass fiber reinforced plastic layer 120, the glass fiber reinforced plastic layer 120 has a contact surface with the goods, and the rubber coating layer 110 is attached to the contact surface. In the embodiment, the glass fiber reinforced plastic layer is glued by laminated glass steel mesh and resin, and has strong plasticity. The glass fiber reinforced plastic plate can be pressed into a chute with different curved surface structures according to the shape, technical requirements and use of the product. The rubber coating layer 110 is attached to the contact surface of the chute to increase the wear resistance of the conveying chute.

[0076] In an embodiment, referring to Figure 1 The protrusion 20 and the chute base plate 10 are integrally formed in a mold. It should be noted that the protrusion 20 and the chute base plate 10 are integrally formed by melting and then cooling and solidifying in a mold, which reduces the process difficulty of producing the conveying chute.

[0077] In an embodiment, referring to Figure 9 The length of the protrusion 20 in the extension direction of the guide surface 211 is L2, and L2 satisfies 6mm≤L2≤25mm. The width of the protrusion 20 in the direction perpendicular to the guide surface 211 is L3, and L3 satisfies 4.5mm≤L3≤8.5mm. The length and width of the protrusion 20 are limited to reduce the manufacturing difficulty and make the goods slide more smoothly.

[0078] In an embodiment, referring to Figure 11 The conveying chute further comprises side plates 30 connected to the chute base plate 10. The chute base plate 10 and the side plates 30 located on both sides thereof enclose the conveying chute.

[0079] The above only describes optional embodiments of the present application, and does not limit the patent scope of the present application. Any equivalent structural transformation made according to the content of the present application specification and drawings, or direct / indirect application in other related technical fields is included in the patent protection scope of the present application.
