Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of hot pressing, and more particularly relates to a hot pressing device and a method for processing a conveying belt by using the same. BACKGROUND

[0002] In the processing of the conveying belt, according to the processing requirements of the conveying belt, the two ends of the conveying belt are first toothed, and then the two ends after toothed are butt-jointed. Then, the butt-joint of the conveying belt is treated by hot melting by using the hot pressing device, so as to improve the firmness of the joint of the conveying belt.

[0003] However, the existing hot pressing device has some problems in processing the conveying belt. In the existing processing of the conveying belt, the butt-joint of the conveying belt is simply placed on the bearing platform, and then the heating mechanism of the hot pressing device is used for pressing and heating. However, the existing hot pressing device often causes the thickness of the butt-joint of the conveying belt to be reduced after hot melting due to the pressure of the heating mechanism, resulting in the thickness of the butt-joint of the conveying belt being inconsistent with other parts. Such thickness difference will cause the processed conveying belt to vibrate when being matched with the machine, thereby reducing the stability of the machine. Especially in the case of small wheel diameter of the machine, the phenomenon of slipping will also occur, which affects the use effect of the conveying belt. In addition, since the conveying belt is directly in contact with the bearing platform, the hot melting part of the conveying belt is easy to overflow during the hot melting process, which will cause the connection line of the butt-joint of the conveying belt to be not clear enough, affecting the appearance and being difficult to meet the quality requirements of the processing of the conveying belt.

[0004] Therefore, the existing hot pressing device still has some problems in processing the conveying belt, which is not conducive to the processing and forming of the conveying belt, and needs to be improved. SUMMARY

[0061] With reference to Figures 1-3 , the embodiments of the present application provide a hot pressing device for hot melting treatment of a to-be-processed conveying belt 1;

[0062] A carrying platform 2 for carrying an interfacing part of the conveying belt 1 to be hot melted;

[0064] A clamping assembly including a first clamping piece and a second clamping piece, the first clamping piece and the second clamping piece are respectively arranged on both sides of the interfacing part along the length direction of the conveying belt 1 to prevent the interfacing part from separating;

[0065] The first clamping piece, the second clamping piece and the interfacing part all have heating surfaces for adapting to the heating mechanism 3, and the heating surfaces of the three are coplanar;

[0066] A flow limiting pad 4 is laid between the conveying belt 1 and the carrying platform 2, and when the conveying belt 1 is in a state of being pressed by the heating mechanism 3, the flow limiting pad 4 is used to reduce the overflow amount of the interfacing part.

[0067] In an embodiment, the hot pressing device further includes a support frame 5 and a lifting assembly, the heating mechanism 3 is connected to the upper end of the support frame 5 through the lifting assembly, and the carrying platform 2 is arranged on the support frame 5 directly below the heating mechanism 3.

[0068] In a specific embodiment, the shape of the cross section of the support frame 5 is E-like.

[0069] In one embodiment, the heating mechanism 3 comprises a housing, a heating plane arranged at the lower end of the housing, and a control end arranged at the side of the housing.

[0070] In one embodiment, the lifting assembly comprises a fixed pulley 6 arranged at the upper end of the support frame 5, and a rope 7, one end of which extends upward from the support frame 5, passes around the fixed pulley 6, and is connected to the heating mechanism 3 downward.

[0071] In one embodiment, the support frame 5 is further provided with an ultraviolet lamp for reflecting the hot melting area on the bearing platform 2. The ultraviolet lamp is not shown in the figure.

[0072] Specifically, when the conveyor belt is processed, the butt joint part of the conveyor belt is placed in the hot melting area of the bearing platform, and then the heating mechanism is driven downward by the rope, so that the heating plane covers the butt joint part of the bearing platform, and the heating plane is controlled by the control end to heat the butt joint part.

[0073] In one embodiment, the bearing platform 2 is symmetrically provided with a first limiting rod 8 and a second limiting rod 9 perpendicular to the length direction of the conveyor belt 1, and the first limiting rod 8 and the second limiting rod 9 are used to limit the butt joint part.

[0074] In one embodiment, the two ends of the first limiting rod 8 and the second limiting rod 9 are provided with fasteners 10 for fixing them on the bearing platform 2.

[0075] In a specific embodiment, the fastener 10 is a bolt.

[0076] Specifically, when the butt joint part of the conveyor belt is placed on the bearing platform, the first limiting rod and the second limiting rod can be moved downward to press the two ends of the butt joint part, and then the first limiting rod and the second limiting rod are fixed on the bearing platform by bolts to limit the butt joint part and ensure the stability of the butt joint part during hot pressing.

[0077] The hot pressing device of the present application has the following three embodiments:

[0078] In the first embodiment, the first clamping piece and the second clamping piece each comprise a clamping plate 11. Specifically, one clamping plate in the first clamping piece and one clamping plate in the second clamping piece are arranged on the two sides of the butt joint part along the length direction of the conveyor belt to clamp the butt joint part.

[0079] In the second embodiment, the first clamping piece and the second clamping piece each comprise two clamping plates 11 and a connecting piece, and the two clamping plates 11 are connected by the connecting piece.

[0080] In one embodiment, each clamping plate 11 is provided with a first mounting hole for mounting a connecting member at both ends thereof.

[0081] In one specific embodiment, the connecting member is a screw rod 12.

[0082] Specifically, after the two clamping plates are connected by the screw rod, the thickness between the two clamping plates can be adjusted according to the thickness of the conveyor belt, so as to improve the utilization rate of the first clamping member and the second clamping member.

[0083] In a third embodiment, the first clamping member and the second clamping member each include a plurality of clamping plates 11 and connecting members stacked and arranged, and the plurality of clamping plates 11 are connected by the connecting members.

[0084] In one specific embodiment, the connecting member is an adhesive tape.

[0085] Specifically, the number of clamping plates is matched according to the thickness of the conveyor belt, and the two ends of the plurality of clamping plates are connected by the adhesive tape, so that the plurality of clamping plates can stably clamp the two sides of the butt joint portion.

[0086] In one specific embodiment, each clamping plate 11 is a flat plate structure made of stainless steel.

[0087] In one embodiment, when the conveyor belt 1 is in a state of being pressed by the heating mechanism 3, the thickness of the flow limiting pad 4 is 0.4mm-0.5mm.

[0088] In one specific embodiment, the flow limiting pad 4 is folded by high-temperature cotton. Since the high-temperature cotton has a compact density and a relatively stable structure, when the conveyor belt is in a state of being pressed by the heating mechanism, the high-temperature cotton is also subjected to the pressure of the heating mechanism, causing the internal structure to shrink, thereby sealing the overflow at the butt joint of the conveyor belt and reducing the possibility of outward diffusion, achieving the effect of reducing the amount of overflow at the butt joint. The melting point of the high-temperature cotton is greater than 200℃, so it will not melt during use. Only after being used for hundreds of times, it needs to be replaced, which has a low utilization rate and cost, and is beneficial to the long-term processing of the conveyor belt.

[0089] Of course, it should be realized that each clamping plate and flow limiting pad of the present application can also be made of other materials, and the present application is not limited thereto. Any material that can achieve the same technical effect as the flow limiting pad of the present application is within the scope of the present application.

[0090] The heat pressing device provided in the present application, in operation, the operator needs to lay the folded flow limiting pad on the bearing platform, then place the butt joint part of the conveying belt in the hot melting area on the flow limiting pad, then place the first clamping piece and the second clamping piece on both sides of the butt joint part, and fix the three on the bearing platform by using the first limiting rod and the second limiting rod, then start the heat pressing device, so that the rope moves on the fixed pulley to drive the heating mechanism to press down on the butt joint part, and then control the heating plane to perform hot melting treatment on the butt joint part by using the control end. With the hot melting process, the heating mechanism is always erected on the first clamping piece and the second clamping piece until the butt joint part is connected, and then the heating mechanism can be moved up, and the first clamping piece and the second clamping piece are gradually removed, and the formed conveying belt is taken out.

[0126] Figure 6 A schematic diagram of the structure of a conveyor belt produced by a method of processing conveyor belts using a hot pressing device, according to a second perspective of Embodiment 1 of the present invention, is shown.
