Description

Technical Field

[0001] The invention relates to the technical field of rubber conveyor belt production, in particular to a demoulding device for producing rubber conveyor belts. Background Art

[0002] The conveyor belt is the main component of the belt conveyor. It is mainly used for large-scale continuous transportation in the coal, mining, metallurgy, chemical industry, construction and transportation sectors. The transported materials are divided into blocks, powders, pastes and piece goods. The conveyor belt industry can be divided into two categories: heavy conveyor belts and light conveyor belts. Heavy conveyor belts use rubber as the main raw material, so they are also called rubber conveyor belts. Their use is concentrated in the fields of heavy industry and infrastructure construction.

[0003] Existing rubber conveyor belts are widely used. Rubber conveyor belts have characteristics such as heat-resistant belts, wear-resistant belts and cold-resistant belts. Rubber conveyor belts need to go through a cooling process during the manufacturing process. The existing cooling method is generally to place the conveyor belt in a cool place to cool it down naturally. Too long cooling time leads to low processing efficiency, so shortening the cooling time can improve the cooling efficiency of the conveyor belt.

[0004] Chinese patent document CN217802800U discloses a forming heat dissipation device for making a rubber conveyor belt, comprising a heat dissipation frame, wherein three horizontal plates are fixedly installed inside the heat dissipation frame and are equidistantly distributed up and down, a through-type fan is fixedly installed inside the horizontal plate, an air duct is fixedly installed at the bottom of the through-type fan, guide plates are fixedly installed inside the left and right sides of the heat dissipation frame, three support plates are fixedly installed inside the heat dissipation frame and are respectively located at the bottom of the three horizontal plates, support seats are fixedly installed on the top and left and right sides of the support plates, two baffles are fixedly installed between the left and right support seats and are distributed front and back, a roller conveyor is fixedly installed between the front and rear baffles, a heat dissipation mechanism located at the bottom of the roller conveyor is fixedly installed between the front and rear baffles, the heat dissipation mechanism is used to dissipate heat and cool down the conveyor belt, and the gap between the roller conveyors is convenient for cool wind to pass through, the components of the heat dissipation mechanism can absorb the heat on the conveyor belt conducted on the roller conveyor and cool it down through water cooling, and cooperate with the heat dissipation effect of the through-type fan to improve the cooling efficiency of the conveyor belt;

[0005] In actual use, this patent shortens the cooling time of the conveyor belt. However, since many lines will be printed on the conveyor belt during the molding process, the conveyor belt may get stuck when it is rolled up, and the conveyor belt cannot be ejected from the mold. The staff has to manually demold the conveyor belt, which is time-consuming and labor-intensive. Summary of the invention

DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0033] Embodiment 1

[0034] like Figure 1 - Figure 2As shown, a demoulding device for producing a rubber conveyor belt comprises a mounting shell 2 and a winding roller 1. The mounting shell 2 is provided with connecting plates 5 at both ends. Two conveying wheels 4 are provided at the upper part of the rear end of the connecting plate 5. A fixing block 3 is provided at the middle of one end of the mounting shell 2 close to each other. The winding roller 1 penetrates the connecting plate 5 at the right part. Figure 2 As shown, a motor is provided at the front end of the winding roller 1, a synchronization device 6 is provided at the front of the mounting shell 2, and forming devices 9 are provided at the upper and lower parts of the rear end of the synchronization device 6. Linkage devices 7 are provided on the left and right sides of the ends away from each other of the two forming devices 9. The multiple linkage devices 7 are movably connected to the fixed blocks 3 on the upper and lower sides respectively. The ends of the multiple linkage devices 7 away from the mounting shell 2 are provided with ejection devices 8, and the two ejection devices 8 respectively penetrate the forming devices 9 on the upper and lower sides;

[0035] The unformed conveyor belt is conveyed by the two conveying wheels 4, and the unformed conveyor belt is passed through the two conveying wheels 4. Then, the synchronous device 6 is used to drive the forming devices 9 on the upper and lower sides to move in opposite directions, so that the unformed conveyor belt can be shaped. At the same time, the two forming devices 9 can also cool the conveyor belt, thereby shortening the cooling time of the conveyor belt. When the synchronous device 6 is working, the linkage devices 7 on the upper and lower sides will also work, so as to eject the formed conveyor belt, which not only prevents the conveyor belt from being damaged during demoulding, but also facilitates the winding of the conveyor belt. A motor is arranged at the front end of the winding roller 1, so when the conveyor belt needs to be wound up, the motor is started to rotate the winding roller 1, so as to wind up the conveyor belt after demoulding.

[0036] like Figure 3 As shown, the synchronization device 6 includes a gear 63 and a hydraulic cylinder 60, the front end of the gear 63 is rotatably connected to the mounting housing 2, racks 64 are provided on the left and right sides of the outer surface of the gear 63, the front ends of the two racks 64 are slidably connected to the mounting housing 2, and the rear ends of the two racks 64 are provided with a synchronization plate 61 on the side away from the gear 63, the front ends of the two synchronization plates 61 are slidably connected to the mounting housing 2, and the left and right parts of the ends of the two synchronization plates 61 close to each other are provided with L-shaped plates 62, and the multiple L-shaped plates 62 are fixedly connected to the forming device 9, the output end of the hydraulic cylinder 60 is fixedly connected to the lower synchronization plate 61, the lower end of the hydraulic cylinder 60 is fixedly connected to the mounting housing 2, a through groove is opened at the bottom of the mounting housing 2, and the hydraulic cylinder 60 is installed at the bottom of the through groove;

[0037] This figure shows the state when the two forming devices 9 are moving away from each other. The hydraulic cylinder 60 is started to move the lower synchronous plate 61 downward, driving the right rack 64 to move downward, thereby causing the gear 63 to rotate, thereby causing the left rack 64 to move upward, thereby driving the two L-shaped plates 62 on the upper and lower sides to move in opposite directions. Since the multiple L-shaped plates 62 are fixedly connected to the forming devices 9 on the upper and lower sides, when the L-shaped plates 62 on the upper and lower sides move in opposite directions, the two forming devices 9 at this time move away from each other, and the conveyor belt is not formed at this time.

[0038] like Figure 4 As shown, the molding device 9 includes a molding shell 91 and a water pump 92. The front end of the molding shell 91 is fixedly connected to the two L-shaped plates 62 respectively. A cooling pipe 90 is arranged inside the molding shell 91. The water inlet end of the water pump 92 is fixedly connected to the left end of the cooling pipe 90. A cooling assembly 93 is arranged at the water outlet end of the water pump 92. T-shaped blocks 94 are arranged at the front of the left and right ends of the molding shell 91. One end of the two T-shaped blocks 94 close to the linkage device 7 is fixedly connected to the linkage device 7.

[0039] When the molding shells 91 on the upper and lower sides are in contact with the conveyor belt, in order to speed up the molding of the conveyor belt, the cooling tube 90 is filled with coolant to cool the conveyor belt, thereby speeding up the molding of the conveyor belt. At the same time, in order to keep the coolant in the cooling tube 90 always cooled, the coolant in the cooling tube 90 is pumped into the cooling assembly 93 by a water pump 92. Therefore, the cooling assembly 93 can be used to cool the coolant in the cooling tube 90, thereby realizing the circulation of the coolant in the cooling tube 90 and ultimately cooling the conveyor belt.

[0040] For details, please refer to Figure 5 The cooling assembly 93 includes a cooling shell 930, a condenser 931 is provided inside the cooling shell 930, the right end of the cooling tube 90 is connected to the condenser 931, a liquid inlet pipe 933 is provided at the upper part of the outer surface of the cooling shell 930, a liquid outlet pipe 932 is provided at the lower part of the outer surface of the cooling shell 930, the interior of the cooling shell 930 is filled with coolant, a semiconductor refrigeration sheet 934 is provided at the right part of the outer surface of the cooling shell 930, the right end of the semiconductor refrigeration sheet 934 is fixedly connected to the T-shaped block 94, and the shape of the condenser 931 is spiral;

[0041] When it is necessary to cool the coolant inside the cooling tube 90, the coolant inside the cooling tube 90 is pumped into the condenser 931 by the provided water pump 92, and the cooling shell 930 is filled with the coolant. The coolant inside the cooling shell 930 is cooled by the provided semiconductor refrigeration sheet 934. Since the condenser 931 is spirally shaped, the flow path of the coolant inside the cooling tube 90 becomes longer, so that the coolant inside the cooling tube 90 is fully cooled, and finally the coolant inside the cooling tube 90 is circulated. The coolant inside the cooling shell 930 can be replaced by the provided liquid inlet pipe 933, and the provided liquid outlet pipe 932 can discharge the coolant inside the cooling shell 930.

[0042] It should be noted that the semiconductor cooling sheet 934 in the present invention is a conventional design in the prior art. The principle is that when current passes through a thermocouple pair formed by connecting a piece of N-type semiconductor material and a piece of P-type semiconductor material, heat transfer will occur between the two ends. The heat will be transferred from one end to the other end, thereby generating a temperature difference to form a hot and cold end, thereby realizing cooling of the transformer oil. The present invention will not elaborate on this in detail.

[0043] like Figure 6 As shown, the ejection device 8 includes an ejection plate 82, and a plurality of ejection rods 80 are provided at one end of the ejection plate 82 close to the molding shell 91, and the plurality of ejection rods 80 all penetrate the molding shell 91, and the plurality of ejection rods 80 are all slidably connected to the molding shell 91, and a compression spring 81 is provided on one side of the outer surface of the ejection rod 80 close to the ejection plate 82, and an end of the ejection plate 82 away from the plurality of compression springs 81 is fixedly connected to the linkage device 7, and the plurality of ejection rods 80 are staggeredly distributed with the cooling pipe 90;

[0044] The state at this time is the ejection state of the conveyor belt. At this time, the multiple compression springs 81 are in a compressed state. At the same time, the multiple ejection rods 80 are arranged to pass through the molding shell 91, so as to eject the molded conveyor belt, thereby facilitating the demolding of the molded conveyor belt.

[0045] like Figure 7 As shown, the linkage device 7 includes two rotating plates 71, a rotating shaft is provided in the middle of the two rotating plates 71, and the rotating shaft is movably connected to the fixed block 3. A movable column 2 72 is provided at the front of the end of the two rotating plates 71 close to each other, and the end of the movable column 2 72 close to the T-shaped block 94 is fixedly connected to the T-shaped block 94. A movable column 1 70 is provided at the rear of the end of the two rotating plates 71 close to each other, and the end of the movable column 1 70 close to the ejection plate 82 is fixedly connected to the ejection plate 82. The shape of the two rotating plates 71 is rhombus;

[0046] The state at this time is the ejection state of the conveyor belt. At this time, the L-shaped plates 62 on the upper and lower sides are away from each other. Since the L-shaped plates 62 on the upper and lower sides are fixedly connected to the upper and lower forming shells 91 respectively, the two forming shells 91 are also in a state of moving away from each other at this time. Since the multiple T-shaped blocks 94 are fixedly connected to the forming shells 91 and the movable column 2 72 on the same side, when the two forming shells 91 move away from each other, the movable column 2 72 on the upper and lower sides will also be driven away from each other, thereby causing the multiple rotating plates 71 to rotate, thereby driving the movable columns 1 70 on the upper and lower sides to approach each other, and driving the multiple ejection plates 82 and the ejection rods 80 on the upper and lower sides to approach each other. At this time, the multiple compression springs 81 are in a compressed state, thereby ejecting the formed conveyor belt, and finally the formed conveyor belt is wound up by the set winding roller 1.

[0047] The specific implementation method is as follows: when the conveyor belt needs to be ejected, the hydraulic cylinder 60 is started to move the lower synchronous plate 61 downward, so that the right rack 64 moves downward, thereby driving the gear 63 to rotate, and the left rack 64 moves upward, so that the L-shaped plates 62 on the upper and lower sides move in opposite directions, so that the upper and lower molding shells 91 are separated from each other, and at the same time, the upper and lower movable columns 72 move with the movement of the molding shell 91, so that the upper and lower multiple rotating plates 71 are rotated, thereby driving the upper and lower movable columns 70 to move toward the side close to each other, so that the two ejection plates 82 also move toward the side close to each other, thereby driving the upper and lower multiple compression springs 81 to separate from the molding shell 91, thereby ejecting the formed conveyor belt.

[0048] Embodiment 2

[0049] This embodiment further improves the linkage device 7, the ejection device 8 and the molding device 9 on the basis of the first embodiment. Figure 8 - Fig.10 As shown, this is the state of the conveyor belt when it is being molded. At this time, the two molding devices 9 are close to each other, so that patterns are printed on the surface of the conveyor belt and the cooling time of the conveyor belt is shortened. At this time, the ejection devices 8 on the upper and lower sides do not eject the conveyor belt, and demolding of the conveyor belt is not achieved.

[0050] like Fig. 9 - Fig.10As shown, the hydraulic cylinder 60 is started to move the lower synchronous plate 61 upward, so that the right rack 64 moves upward, and the gear 63 rotates, so that the left rack 64 moves downward, and the L-shaped plates 62 on the upper and lower sides are close to each other, thereby driving the molding shells 91 on the upper and lower sides to approach each other, so as to form the surface of the conveyor belt. During the molding process, the conveyor belt is cooled by the coolant inside the cooling pipe 90, so as to accelerate the cooling speed of the conveyor belt. When the molding shells 91 on the upper and lower sides are close to each other, the T-shaped blocks 94 on the upper and lower sides are also close to each other, so that the movable columns 2 72 on the upper and lower sides are also close to each other, and the multiple rotating plates 71 are rotated, so as to drive the movable columns 1 70 on the upper and lower sides to move away from each other, so that the ejector plates 82 on the upper and lower sides are moved away from each other, so that the ejector rods 80 on the upper and lower sides enter the molding shell 91. At this time, the multiple ejector plates 82 are in an expanded state, and the state of demolding the conveyor belt is not achieved at this time.

[0051] The specific implementation method is as follows: when the conveyor belt needs to be formed, the hydraulic cylinder 60 is started to move the lower synchronous plate 61 upward, thereby causing the right rack 64 to move upward, and the gear 63 to rotate, thereby causing the left rack 64 to move downward, and the L-shaped plates 62 on the upper and lower sides to approach each other, thereby driving the upper and lower forming devices 9 to approach each other. The two forming devices 9 can form the conveyor belt and shorten the cooling time. At this time, the multiple ejector rods 80 are inside the forming shell 91 and do not eject the conveyor belt. At this time, the conveyor belt cannot be demolded.

[0052] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
