In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

When the conveying belt is used, the conveying belt needs to be sleeved on the power assembly, and the power assembly drives the conveying belt to convey materials. In this application, the term "outer" refers to the side of the belt facing away from the power module, and the term "inner" refers to the side of the belt facing the power module.

Referring to fig. 1 to 9, a method for butting a large-inclination-angle conveyor belt according to the present invention will be described. The butt joint method of the large-inclination-angle conveying belt comprises the following steps:

s10: respectively obtaining sections to be processed 10 with preset lengths at two ends of a conveying belt, and stripping the wavy flanges 20 and the partition boards 30 of the sections to be processed 10 from the base belt 40;

s20: cutting off the corrugated ribs 20 and the partition boards 30 on one of the sections to be processed 10;

s30: processing butt joint steps 11 which are correspondingly attached to each other on butt joint ends of base bands 40 of two sections to be processed 10 respectively;

s40: respectively coating hot viscose on the two butt joint steps, and realizing the connection of the base bands 40 in the two sections to be processed 10 through hot bonding to form butt joint sections;

s40: the corrugated ribs 20 and the baffle plates 30 on the other section to be treated 10 are cold glued to the docking section.

It should be noted that the abutting surface of the abutting step 11 of one of the sections to be processed 10 faces outward, the abutting surface of the abutting step 11 of the other section to be processed 10 faces inward, both the abutting surfaces are step-shaped, and the thermal adhesive is also coated on the abutting surface of the abutting step 11.

Compared with the prior art, in the butt joint method for the large-inclination-angle conveyor belt provided by the embodiment, when the conveyor belt is connected, the wavy flanges 20 and the partition plates 30 are used as one part, the base belt 40 is used as the other part, the base belt 40 and the base belt 40 are thermally bonded by using thermal bonding adhesive, the butt joint step 11 is further processed at the butt joint position, the contact area between the base belt 40 and the base belt 40 is increased by coating the thermal bonding adhesive on the butt joint surface of the butt joint step 11, so that the area of the butt joint position of the base belt 40 coated with the thermal bonding adhesive is increased, and the connection strength between the base belt 40 and the base belt 40 is enhanced; the corrugated flanges 20, the partition plates 30 and the base belt 40 are bonded by a cold method (using cold glue), different adhesives are adopted at different positions and matched with the butt joint step 11, so that the strength of the joint of the base belt 40 on the conveying belt is increased, and the service life of the conveying belt is prolonged; and when the base band 40 is butted, the butt joint step 11 is adjusted to correspond, which is different from the prior art that the corresponding degree of every two clips is adjusted, the adjusting process is simplified, and the installation requirement is reduced.

In some embodiments, referring to fig. 2 to 4, step S10 specifically includes:

s11: measuring a section to be processed 10 with a preset length, and marking on a conveying belt;

s12: cutting off an upper isolation adhesive layer 41 and at least one wire layer 42 of the base tape 40 at one side of the section to be processed 10, and fixing the flanges and the partition boards 30 on the outer side of the upper isolation adhesive layer 41;

s13: pulling the cut upper isolation glue layer 41 and the wire layer 42 together to complete the stripping of the corrugated rib 20 and the separator 30;

cold glue application applies cold glue between the wire layer 42 and the base tape 40.

In operation, the release glue layer 41 and the wire layer 42 may not be peeled off, that is, the corrugated rib 20 and the separator 30 are peeled off from the base tape 40 separately, and the corrugated rib 20 and the separator 30 need to be peeled off separately, which is inconvenient not only for operation but also for adjusting the positions of the corrugated rib 20 and the separator 30 during bonding. Through peeling off wavy flange 20, baffle 30, go up isolation glue film 41 and line layer 42 together, can not only guarantee the position of wavy flange 20 and baffle 30 in the time of the subsequent bonding, can also guarantee to go up isolation glue film 41 and line layer 42 and play the connection effect in wavy flange 20 and the baffle 30 inboard after peeling off, when guaranteeing joint strength for wavy flange 20 and baffle 30 are as an organic whole, prevent to break the dispersion.

It is worth mentioning that: in the case where corrugated ribs 20 and spacers 30 are individually peeled from base tape 40, base tape 40 after the peeling is described as base tape 40 having upper separator layer 41 and wire layer 42; however, when corrugated ribs 20, spacers 30, upper release adhesive layer 41, and wire layer 42 are peeled off together from base tape 40, base tape 40 after the peeling is described as base tape 40 after upper release adhesive layer 41 and wire layer 42 are removed.

In some embodiments, referring to fig. 2-4, the number of wire layers 42 that are cut apart is one or two. Base tape 40 normally includes about 6 layers of thread layers 42, and the greater the number of layers of thread 42 to be peeled off, the better the connectivity between corrugated ribs 20 and spacers 30, but the too much of layers of thread 42 to be peeled off does not perform the bonding operation between base tape 40, so it is necessary to ensure the connectivity between corrugated ribs 20 and spacers 30 and the connection strength between base tapes 40, and the number of layers of thread 42 to be peeled off is one or two.

In some embodiments, the step of applying the cold glue further comprises:

polishing the inner side of the wire layer 42 and the outer side of the base tape 40;

and respectively and uniformly coating cold adhesive on the inner side surface of the polished wire layer 42 and the inner side surface of the base belt 40.

In some embodiments, after the application of the cold glue, the cold glue is baked to keep the cold glue in a semi-dry state, and the thread layer 42 is applied to the base tape 40 until the cold glue solidifies. The cold viscose glue is adopted for bonding, the viscosity of the cold viscose glue can be improved by proper baking, the bonding is carried out in a semi-dry state, the bonding effect is optimized, and the bonding strength is improved.

Through the processing mode, the processing of the butt joint step 11 can be assisted through scribing and the like, and the attractiveness of the processing of the butt joint step 11 and the accuracy of the size are guaranteed.

In some embodiments, the docking steps 11 on the two sections to be processed 10 may adopt the structure shown in fig. 4 to 5. Referring to fig. 4 to 5, the docking steps 11 on the two sections to be processed 10 correspond one to one, so that the outer sides of the two sections to be processed 10 are flush and the inner sides are flush. The butt joint steps 11 one-to-one correspond, so that the thickness spliced by two butt joint steps 11 corresponding to each group is consistent with the thickness of the base band 40 on any one section to be processed 10, the inner side surface and the outer side surface of the formed butt joint section are smooth, the outer side surface or the inner side surface is prevented from bumping when being used, the transportation is influenced, traces at the joint part are not obvious, and the attractiveness is enhanced.

In some embodiments, the connection between the abutting steps 11 may be configured as shown in fig. 4 to 5.
