Description

Technical Field

[0001] The utility model relates to the technical field of belt joints, in particular to a belt joint vulcanizing device. Background Art

[0002] Belt joint vulcanization is a method of fusing the belt joint part with the new belt material by applying heat and pressure. This method is mainly used to connect or repair the joint part of the conveyor belt to ensure the continuous operation of the conveyor belt and extend its service life.

[0003] Before vulcanization, the belt joint needs to be cleaned with acetone to remove sticky debris from the surrounding area, then glue is applied and finally vulcanized. Among the currently used vulcanization equipment, such as the belt joint vulcanization device disclosed in patent CN204977175U, when in use, first connect the upper and lower vulcanization plates, insert the clamping plates on both sides of the tape to avoid air gaps; then connect the tape vulcanizer and water pump, set the vulcanization temperature to 145°, and then pressurize the water pump to 1.8 MPa; after the water pressure reaches 1.8 MPa, turn on the vulcanizer power to increase the temperature. When the temperature rises to 145°, start the vulcanization timer for 45 minutes and maintain a constant temperature of 145±2°; after 45 minutes, stop heating and let the belt cool down before removing it.

[0004] However, the existing belt joint vulcanization process requires assembly and disassembly of the vulcanization device, tightening large bolts, pressurizing and draining the water pressure belt, etc. The use process is relatively cumbersome. The entire vulcanization process takes about 1 hour and is inefficient, so it needs to be improved. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0022] In addition, the terms "first," "second," and so on, used in this utility model are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one of these features.

[0023] In the description of the embodiments, unless otherwise specified or limited, the terms "disposed" and "connected" should be understood broadly. For example, they can refer to fixed, removable, or integral connections; mechanical or electrical connections; direct connections, connections through an intermediary medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on their specific circumstances.

[0024] like Figure 1-2 As shown, the belt joint vulcanization device in this embodiment includes a base 10, a flip seat 20, an upper heating plate 30, a lower heating plate 40, a driving cylinder 50 and a locking cylinder 60. The base 10 is provided with a groove 11 with an opening on one side. The setting of the groove 11 facilitates the placement of the annular belt on the base 10 and makes the position of the joint to be connected between the upper heating plate 30 and the lower heating plate 40 to facilitate subsequent heating and vulcanization.

[0025] The flip seat 20 is arranged above the base 10 and one end of the two is rotatably connected by a rotating shaft 12. The upper heating plate 30 is arranged at the bottom of the flip seat 20, and the lower heating plate 40 is arranged at the top of the base 10. The upper heating plate 30 and the lower heating plate 40 can adopt electric heating plates commonly used in this field. The electric heating plate has the advantages of fast heating speed, uniform heating, high stability, and easy regulation, which is beneficial to improving the heating and vulcanization efficiency of the belt joint.

[0026] A first heat insulation plate 70 is provided between the upper heating plate 30 and the flip seat 20, and a second heat insulation plate 80 is provided between the lower heating plate 40 and the base 10. The first heat insulation plate 70 and the second heat insulation plate 80 are used to isolate the heat of the upper heating plate 30 and the lower heating plate 40 to prevent it from being transferred to the flip seat 20 and the base 10, thereby creating the risk of accidental scalding of the staff.

[0027] The driving cylinder 50 is arranged on a side close to the rotating shaft 12, and the cylinder body of the driving cylinder 50 is rotatably connected to the flip seat 20 through the first support 21, and the piston rod end of the driving cylinder 50 is rotatably connected to the base 10 through the second support 22; when the driving cylinder 50 performs a telescopic action, the piston rod direction pushes the cylinder body to move up and down, thereby driving the flip seat 20 to flip around the base 10. When the flip seat 20 is lifted, the belt can be placed on the lower heating plate 40. When the flip seat 20 falls, the upper heating plate 30 can be buckled on the lower heating plate 40 to heat and apply pressure to the belt joint, thereby completing the vulcanization of the belt joint.

[0028] The locking cylinder 60 is arranged at the front end of the flip seat 20, and the front end of the base 10 is provided with a locking hole 13. The piston rod of the locking cylinder 60 is movably connected to the locking hole 13; when the piston rod of the locking cylinder 60 is extended, it enters the locking hole 13, thereby locking the position between the flip seat 20 and the base 10.

[0029] The driving cylinder 50 and the locking cylinder 60 are both driven by the hydraulic station 90 .

[0030] like Figure 3 As shown, the front end of the flip seat 20 is provided with an auxiliary positioning stud 100, and the front end of the base 10 is provided with an auxiliary positioning sleeve 110. The auxiliary positioning stud 100 is rotatably connected to the flip seat 20 in a threaded manner, and the auxiliary positioning stud 100 is movably connected to the auxiliary positioning sleeve 110.

[0031] Before the locking cylinder 60 is positioned with the locking hole 13, the auxiliary positioning stud 100 can be manually rotated to gradually extend it into the auxiliary positioning sleeve 110. The auxiliary positioning sleeve 110 is provided with an internal thread. The auxiliary positioning stud 100 is rotated to be threadedly connected with the auxiliary positioning sleeve 110. In the process of rotating the auxiliary positioning stud 100, the position between the flip seat 20 and the base 10 can be fine-tuned, so that the locking cylinder 60 is aligned with the locking hole 13, which helps to quickly and accurately position the flip seat 20 and the base 10.

[0032] like Figure 4 As shown, a positioning plate 120 is provided on each of the front and rear sides of the lower heating plate 40, and a plurality of first positioning holes 121 are provided on the positioning plate 120. A positioning bar 122 is provided on each of the left and right sides of the lower heating plate 40, and second positioning holes 123 are provided at both ends of the positioning bar 122. The first positioning hole 121 and the second positioning hole 123 are connected by a positioning column 124; by adjusting the spacing between the left and right positioning bars 122, the joint requirements of belts of different widths can be adapted.

[0033] The lower heating plate 40 is connected to both sides of the base 10 through multiple buffer members 130. The buffer members 130 can adopt structures such as mechanical springs, gas springs or hydraulic springs, so as to play a certain buffering role when the upper heating plate 30 is pressed down, preventing the upper heating plate 30 and the lower heating plate 40 from causing excessive extrusion on the belt.

[0034] The belt joint vulcanizing device of the present invention drives the turning seat 20 to turn up and down around the rotating shaft 12 by driving the oil cylinder 50, so that the upper heating plate 30 and the lower heating plate 40 heat, pressurize and vulcanize the belt joint on the base 10, so that the belt joint is connected. The whole process is simple to operate, and the average vulcanization time is 10-15 minutes. Compared with the traditional vulcanization method, the efficiency is improved by 4-6 times, saving manpower and equipment investment costs for production enterprises.

[0035] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention. In addition, the technical solutions of the various embodiments may be combined with each other, but this must be based on the fact that they can be implemented by a person of ordinary skill in the art. If the combination of technical solutions is inconsistent or cannot be implemented, it shall be deemed that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.
