Description

Technical Field

[0001] The utility model relates to the technical field of rubber conveyor belts, in particular to an automatic gluing device for forming edges of conveyor belts. Background Art

[0002] Conveyor belts play a vital role in various industries, especially heavy-duty transportation. As conveyor belts develop towards longer distances, higher speeds, wider widths, and larger conveying capacities, they are increasingly susceptible to wear and tear during use. This is especially true for the edges of conveyor belts, which, lacking support from a skeleton material, constantly rub against the conveyor's rollers during transportation. Over time, this can lead to quality issues such as edge leakage, wear, shedding, and delamination.

[0003] To address conveyor belt edge quality issues, edge banding strips are often applied or extruded onto the edges of the belt blank during the belt forming process to improve the wear resistance and aesthetics of the belt edges. However, because edge banding strips are a secondary process and are not integral to the conveyor belt before vulcanization, they can be easily affected by the edge banding strip formulation, on-site operating temperature, and application or extrusion pressure, resulting in a risk of poor adhesion and strip detachment.

[0004] To address this issue, prior to applying / extruding the edge banding strips, the edges of the conveyor belt blank must be pre-coated with adhesive slurry to improve adhesion between the edge banding strips and the belt edges. Adhesive slurry is a colloidal solution formed by dissolving a specific proportion of rubber compound in a suitable solvent. It is used to bond rubber components and boasts strong stability, strong adhesion before vulcanization, and high bond strength after vulcanization. However, applying the adhesive slurry currently requires manual labor, requiring mixing and then applying it to the edges of the conveyor belt with a brush. This manual process can easily lead to uneven application, increased labor costs, and material waste.

[0005] Therefore, how to avoid uneven application of the glue, increased labor costs, material waste, etc. is a technical problem that those skilled in the art currently need to solve. Utility Model Content

[0037] The utility model aims to provide an automatic gluing device for forming edges of conveyor belts, which can avoid uneven gluing, increased labor costs, material waste and the like.

[0038] See also Figure 1 To achieve the above-mentioned purpose, the utility model provides an automatic gluing device for forming edges of conveyor belts, comprising a material box and a gluing assembly.

[0039] The material box includes an upper material box 11 and a lower material box 12 which are arranged one above the other. The lower material box 12 is used to store glue 13. The upper material box 11 and the lower material box 12 are connected to form a support platform 14 for carrying the edge of the conveyor belt blank.

[0040] The upper material box 11 and the lower material box 12 are connected by a connecting piece 15. As an option, the connecting piece 15 can be a hinge to achieve relative rotation of the upper material box 11 and the lower material box 12, so as to facilitate accurate positioning of the upper material box 11 relative to the lower material box 12. The upper material box 11 and the lower material box 12 can also be detachably connected by means of bosses and grooves. For example, a groove is provided on the lower material box 12, and a boss is provided on the upper material box 11. The upper material box 11 is provided with a handle, and the upper material box 11 can be separated from the lower material box 12 by the handle, which facilitates the addition of glue 13 and improves work efficiency.

[0041] The slurry coating assembly is arranged in the upper material box 11, and the slurry coating assembly includes a first slurry coating member partially extending to the support platform 14 to contact the edge of the conveyor belt blank, and a second slurry coating member that can contact the glue 13 and transfer it to the first slurry coating member to coat the edge of the conveyor belt blank.

[0042] As the forming vehicle continuously moves, the edge of the conveyor belt embryo continuously moves along a fixed direction, and the automatic gluing device is arranged on both sides of the conveyor belt embryo, so that the glue 13 on the edge of the conveyor belt embryo can be smeared at the same time.

[0043] The upper material box 11 and the lower material box 12 are connected to form a support 14 for carrying the edge of the conveyor belt blank. The formed edge of the conveyor belt needs to be moved in a directional manner to the next process. Through the setting of the support 14, the formed edge of the conveyor belt is always in contact with the first coating member that extends to the support 14 during the movement. The second coating member contacts the glue 13 and transfers it to the first coating member to coat the edge of the conveyor belt blank. No manual operation is required. As the forming vehicle continues to move, the automatic gluing device also continuously and evenly applies the glue 13 to the edge of the conveyor belt blank, which can avoid uneven application of the glue 13, increased labor costs, material waste and the like.

[0044] In this embodiment, the first slurry coating member includes a first fixed rod 211, a straight barrel portion 212 and a first gear 213. The first fixed rod 211 is rotatably connected to the upper material box 11 through a first bearing; the straight barrel portion 212 is connected to the end of the first fixed rod 211 away from the upper material box 11. The straight barrel portion 212 is a cylindrical structure. The straight barrel portion 212 includes a first circumferential surface for contacting the edge of the conveyor belt blank. The first fixed rod 211 can be axially limited by the first bearing so that the first fixed rod 211 can only It can rotate around its own axis, thereby causing the straight cylinder part 212 fixedly connected to the first fixed rod 211 to rotate accordingly. The first fixed rod 211 can also be fixedly connected to the upper material box 11 according to actual needs, and a bearing is set between the first fixed rod 211 and the straight cylinder part 212 so that the straight cylinder part 212 can rotate relative to the first fixed rod 211; the first gear 213 is connected to the bottom of the straight cylinder part 212, and when the edge of the conveyor belt embryo moves, it drives the straight cylinder part 212 and the first gear 213 to rotate around its own axis.

[0045] The second slurry coating member includes a second fixed rod 221, a conical cylinder portion 222 and a second gear 223. The second fixed rod 221 is rotatably connected to the upper material box 11 through a second bearing; the conical cylinder portion 222 is connected to the end of the second fixed rod 221 away from the upper material box 11, the conical cylinder portion 222 is a frustum-shaped structure, and the axis of the conical cylinder portion 222 is inclined relative to the vertical surface, so that any point on the second circumferential surface is at a different height as the conical cylinder portion 222 rotates around its own axis, that is, the conical cylinder portion 222 includes a second circumferential surface partially immersed in the glue 13, and the second gear 223 The second gear 223 is connected to one end of the conical cylinder portion 222 away from the second fixed rod 221, and the second gear 223 is meshed with the first gear 213, and the axis of the second gear 223 is set at an angle to the axis of the first gear 213. The lower part of the second circumferential surface during the rotation process can contact the glue 13, so that the second circumferential surface is hung with the glue 13. When the above-mentioned lower part continues to rotate to a higher position (close to the first circumferential surface), the glue 13 contacts the first circumferential surface and is partially transferred to the first circumferential surface. During the rotation of the first circumferential surface, the glue 13 is attached to the edge of the conveyor belt blank.

[0046] It should be noted that the second fixed rod 221 can be axially limited by a second bearing so that the second fixed rod 221 can only rotate around its own axial direction, thereby causing the conical cylinder portion 222 fixedly connected to the second fixed rod 221 to rotate accordingly. The second fixed rod 221 can also be fixedly connected to the upper material box 11 according to actual needs, and a bearing can be set between the second fixed rod 221 and the conical cylinder portion 222 so that the conical cylinder portion 222 can rotate relative to the second fixed rod 221. No specific limitation is made here, and it is sufficient to achieve the above purpose.

[0047] It can be understood that the second circumferential surface is adjacent to the first circumferential surface, and there is a gap between the second circumferential surface and the first circumferential surface. The angle between the busbar on the second circumferential surface and the axis of the tapered cylinder portion 222 is equal to the angle between the axis of the straight cylinder portion 212 and the axis of the tapered cylinder portion 222, so as to achieve uniform transfer of the mortar 13 from the second circumferential surface to the first circumferential surface. Both the second circumferential surface and the first circumferential surface are provided with patterns that increase the friction with the mortar 13 for the adhesion of the mortar 13.

[0048] Among them, the length and position of the first fixed rod 211 and the second fixed rod 221 can be adjusted according to actual needs to change the distance between the tapered portion 222 and the straight portion 212, thereby increasing the adhesion effect of the glue 13. At the same time, the corresponding pattern can be engraved according to the specific viscosity of the glue 13. When it needs to be applied in different scenarios, it is only necessary to disassemble the upper material box 11 and replace the corresponding first coating part and the second coating part.

[0049] In this embodiment, the material box is connected to a bracket 3, which is located on the side of the lower material box 12 away from the upper material box 11 to support the lower material box 12. The automatic gluing device also includes a base 4, which is provided with two parallel and spaced-apart slide rails. A slider that can move along the extension direction of the slide rail is provided at the bottom of the bracket 3 so that the bracket 3 and the base 4 can slide relative to each other.

[0050] Among them, a fixing nut 31 is also provided at the bottom of the bracket 3, and the fixing nut 31 is located between the two slide rails. The screw 41 is rotatably arranged on the base 4. The axes of the screw 41 and the slide rails are parallel to each other, and the screw 41 is passed through the fixing nut 31, so that the fixing nut 31 driven by the screw 41 drives the bracket 3 to move along the extension direction of the slide rail.

[0051] A handwheel 42 is provided at one end of the screw 41, and the other end of the screw 41 is connected to the base 4 through a third bearing 32. The axial movement of the screw 41 can be limited by the third bearing 32, and the handwheel 42 is used to drive the screw 41 to rotate around its own axis. The handwheel 42 can be used to adjust the bracket 3 to move closer to and away from the edge of the conveyor belt embryo, thereby making the straight cylinder part 212 closer to and away from the edge of the conveyor belt embryo, so as to ensure that the straight cylinder part 212 can be driven to rotate when the edge of the conveyor belt embryo moves.

[0052] In addition, in order to facilitate the observation of the remaining amount of slurry 13 in the lower material box 12, it is possible to consider opening transparent windows on the upper material box 11 and the lower material box 12. When the transparent window is set on the upper material box 11, it is possible to consider setting a float on the upper layer of the slurry 13 on the lower material box 12, and at the same time limit the range of movement of the float by the limiter to avoid contact with the first coating member and the second coating member. By observing the change in the height of the float, the remaining amount of the slurry 13 can be obtained, so that people can judge whether it is necessary to add slurry 13; when the transparent window is set on the lower material box 12, a liquid level scale can be set on the transparent window at the same time. The liquid level height of the slurry 13 can be clearly known through the color difference between the color of the slurry 13 and the color of the transparent window, so that people can judge whether it is necessary to add slurry 13; a liquid level gauge can also be set on the lower material box 12 to detect the liquid level height of the slurry 13.

[0053] Taking the steel cord flame retardant conveyor belt as an example, the gluing process of the automatic gluing device is as follows: first, open the upper material box 11, pour the stirred glue 13 into the lower material box 12, and cover the upper material box 11; by turning the hand wheel 42, control the automatic gluing device to move left and right, so that the straight barrel portion 212 of the first gluing member is close to the edge of the conveyor belt blank; fix the automatic gluing device as a whole to the rear of the forming vehicle. After the steel cord conveyor belt blank is cold-pressed and trimmed, the edge of the blank slides relative to the straight barrel portion 212 through the movement of the forming vehicle, driving the straight barrel portion 212 to rotate, and the first gear 213 is engaged with the second gear 223, thereby driving the second gear 223 to rotate, and the glue 13 in the lower material box 12 is passed through the tapered barrel portion 222 and the straight barrel portion 212 to mix the glue. 13 is evenly applied to the edge of the belt embryo; as the forming vehicle continuously moves, the automatic gluing device also continuously and evenly applies the glue 13 to the edge of the conveyor belt embryo; when the forming vehicle forms a conveyor belt, during this period, the solvent in the glue 13 on the edge of the belt embryo is also evaporated, and then the subsequent process (sticking the edge banding strip) can be carried out. At this time, due to the presence of the glue 13, the edge banding strip can be easily pasted on the edge of the belt embryo and firmly pasted; the belt embryo with the edge banding strip can enter the vulcanizing plate for vulcanization to produce a finished conveyor belt, which improves the coating efficiency, avoids the glue 13 dripping and flowing, causing environmental pollution, and saves materials; the adaptability is wide, and this device is suitable for various conveyor belt production needs, and can be used for the production of steel cord conveyor belts, whole core conveyor belts, layered belts, aramid belts, etc.

[0054] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0055] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0056] This article uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications also fall within the scope of protection of the present invention.
