Abstract
The utility model provides a structure is spliced to belt rubber joint wearing and tearing back secondary, including gluing joint A end and gluing joint B end, glue joint A end and glue joint B end top and link up the groove that splices of seting up the step form, glue and connect the inslot to install and splice the strip with splicing groove shape size assorted, splice a top surface and glue joint A end top surface and glue joint B end top surface and flush. This secondary structure of gluing can carry out the secondary to belt cross under the condition that does not change belt length and glue to glue the back and do not influence the belt sweeper and use, prolonged the life of belt, practiced thrift band conveyer's use cost.
Description
Technical Field
The utility model relates to a belt splices technical field, especially relates to a structure is spliced to belt glue joint wearing and tearing back secondary.
Background
When a belt conveys a material with high water content, the part with smaller particles in the material is adhered to the surface of the belt to form accumulated materials and accumulated mud on the surface of the belt, a sweeper is usually additionally arranged at the head of the belt to scrape the accumulated materials and the accumulated mud on the surface of the belt, but the wear of the head of the belt is accelerated after the sweeper is additionally arranged at the head of the belt, and particularly the wear of the rubber joint of the belt is serious. If the tensioning mode of the belt is a counterweight mode, the length of the belt has allowance, the rubber joint can be cut off, the handover treatment is carried out again, and the service life of the belt is prolonged. But partial belt adopts the tensioning mode that the lead screw was adjusted because space restriction, takes modes such as "lid quilt" to handle when belt cross joint department wearing and tearing are serious, and the sweeper is incompatible with belt "lid quilt" department this moment, either demolishs the sweeper, or changes the belt.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a secondary glued structure behind belt rubber joint wearing and tearing to solve traditional lid and handle back belt surface arch by son mode, compatible poor problem improves the life of belt.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a belt rubber joint wearing and tearing back secondary splices structure, connects A end and gluey joint B end including gluing, glue joint A end and glue joint B end top and link up the gluey groove of having seted up the step form, glue and connect the inslot to install and glue the bonding strip of joining of groove shape size assorted, glue a top surface and glue joint A end top surface and glue joint B end top surface and flush.
Furthermore, in order to increase the contact area between the glue joint strip and the glue joint groove and ensure the reliable mechanical strength of the joint; the total length L of the glue joint groove is not less than the length of a wear area at the glue joint, the minimum depth H is one sixth to one fourth of the total thickness of the belt, and the maximum depth H is one third to two thirds of the total thickness of the belt. The lap length of the end A or the end B of the glue joint and the glue joint striplIs one third to one half of the total length L of the glue adhering groove.
The utility model has the advantages of as follows:
1. the belt rubber joint is subjected to secondary rubber joint under the condition of not changing the length of the belt, so that the service life of the belt is prolonged;
2. the normal use of the belt cleaner is not influenced after the secondary adhesive joint, and the compatibility is good;
3. adopt the same material to glue the strip and carry out the secondary and glue, can effectively prolong the life of the restricted, big, the serious belt of belt cross joint wearing and tearing of belt length of belt, transportation material viscosity.
Drawings
FIG. 1 is a schematic view of the structure of the glue joint of the present invention,
FIG. 2 is a schematic view of the secondary gluing structure of the present invention;
in the figure, the end A of the 1-glue joint, the end B of the 2-glue joint, the 3-glue groove and the 4-glue strip are arranged.
Detailed Description
As shown in fig. 1-2, a secondary cementing structure after belt rubber joint is worn comprises a rubber joint end a 1 and a rubber joint end B2, wherein the tops of the rubber joint end a 1 and the rubber joint end B2 are communicated with a cementing groove 3 with a step shape, a cementing strip 4 with a shape and a size matched with that of the cementing groove 3 is arranged in the cementing groove 3, and the top surface of the cementing strip 4 is flush with the top surface of the rubber joint end a 1 and the top surface of the rubber joint end B2.
The total length L of the glue joint groove 3 is not less than the length of a wear area at the glue joint, the minimum depth H is one sixth to one fourth of the total thickness of the belt, and the maximum depth H is one third to two thirds of the total thickness of the belt.
The lap length of the end 1 of the glue joint A or the end 2 of the glue joint B and the glue joint strip 4lIs one third to one half of the total length L of the gluing groove.
The secondary adhesive bonding structure will be described with reference to the following specific embodiments.
Taking a 500mm wide, (rubber-nylon-rubber) three-layer composite belt as an example, the thicknesses of an upper rubber layer, a nylon core layer and a lower rubber layer of the belt are all 3mm.
Firstly, observing the length of a wear area at a rubber joint of a belt, then cutting the wear surface at the top of the end A of the rubber joint, wherein the cutting length is more than 20cm longer than the wear length, completely cutting off the wear part of the rubber layer at the end A of the rubber joint (the cutting depth is 3 mm), overlapping the non-wear part with a rubber bonding strip 4 (the remaining length is one third of the length of the whole rubber bonding groove), and then cutting off the wear part at the end B of the rubber joint (the cutting depth is 4 mm); then, manufacturing the adhesive strips 4 by taking belt spare parts of the same type, removing the adhesive layer surface under the adhesive strips 4, and reserving the adhesive layer surface (3 mm) and the wire layer (1 mm); the length of the glue joint strip 4 is from the root of the part, which is not worn, of the glue joint A end to the cutting part (namely the length of the glue joint groove) of the glue joint B end, the thicknesses of two ends of the glue joint strip 4 are respectively 4mm and 2mm, and the lap length l is consistent with the length of the part, which is reserved, of the glue joint A end; then, respectively cutting off 1mm of the upper rubber layer of the reserved part of the A end of the rubber joint and the wire layer below the upper rubber layer to match with the rubber joint strip 4; and finally, placing the glue joint strip 4 into a glue joint groove after gluing to finish secondary glue joint of the belt glue joint.
And the secondary gluing structure adopts a step mode to glue, increases the contact area between the gluing strip and the gluing groove, and has good stress condition, small mechanical loss in movement and large bonding force, and is not easy to crack.
To sum up, adopt the belt rubber joint secondary splices the structure and can prolong belt life under the condition of not shortening belt length, practices thrift belt feeder running cost, still can use with belt feeder sweeper compatibility simultaneously.
