Description
Technical Field
[0001] This utility model relates to the field of flat vulcanizing machine technology, specifically a flat vulcanizing machine for producing narrow V-belt rubber bands with a safety device. Background Technology
[0002] Narrow V-belts are a unique type of conveyor belt, a mechanical device used for transmitting force and transporting goods. They have high load-bearing capacity, long service life, and are suitable for applications with large load fluctuations and harsh working conditions.
[0003] When producing narrow V-belts in rubber bands, vulcanization is required using a flat vulcanizing machine. The main function of the flat vulcanizing machine is to provide the pressure and temperature required for vulcanization. Patent announcement number CN216068300U discloses a cooling device for a flat vulcanizing machine, which includes interconnected water treatment, circulation, cooling, spraying, and collection mechanisms. These mechanisms form a loop. Both the spraying and collection mechanisms are mounted on the pre-installed flat vulcanizing machine. The spraying mechanism cools the processed rubber parts. This technical solution involves spraying cooling water onto the molded, high-temperature rubber parts through the spraying mechanism, thereby cooling the surface of the rubber parts.
[0004] However, this technical solution requires opening the mold before the rubber parts can be fully cooled by water spraying. The heat generated when opening the mold at high temperatures can easily burn workers, so workers need to stay away when opening the mold, which is quite troublesome. Although the technical solution is equipped with a collection mechanism, workers still need to clean the water on the rubber parts and the lower mold after cooling, which increases the number of production steps. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a flat vulcanizing machine with a safety device for producing narrow V-belt rubber bands, thus solving the problems existing in the prior art.
[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a flat vulcanizing machine for producing narrow V-belts with safety devices, comprising a base, a fixed plate and a hydraulic telescopic rod on the top of the base, a control box on the fixed plate, a movable plate on the hydraulic telescopic rod, heating plates on opposite sides of the fixed plate and the movable plate, a lower mold connected to the bottom heating plate, and an upper mold connected to the top heating plate;
[0007] The lower mold is uniformly provided with grooves, and both the lower mold and the upper mold are connected to water-cooling safety devices.
[0008] Both the lower mold and the upper mold are provided with through slots, and heat transfer plates are evenly arranged in the through slots. The heat transfer plates are evenly provided with through holes, and both the lower mold and the upper mold are provided with air-cooling safety devices opposite to the through slots.
[0009] Preferably, the water-cooled safety device includes channels evenly formed on the lower mold and the upper mold, with connecting pipes provided on both the front and rear sides of the channels, and fixing pipes connected to both the front and rear connecting pipes, and installation pipes provided on both fixing pipes.
[0010] Preferably, the holes on the lower mold are located near the top of the lower mold and are staggered with the grooves, while the holes on the upper mold are located near the bottom of the upper mold.
[0011] Preferably, the air-cooled safety device includes two baffles, which cover both ends of the through groove. The bottom of each baffle is connected to an electric telescopic rod, the bottom electric telescopic rod is connected to a fixed plate, and the top electric telescopic rod is connected to a movable plate.
[0012] Preferably, an air supply pipe is connected to the left end baffle, and flexible hoses are evenly connected to the air supply pipe. The flexible hoses are connected to the air supply port of the pump. The bottom pump is mounted on the fixed plate, and the top pump is mounted on the movable plate.
[0013] Preferably, the pump has a valve at its air outlet and a filter cover threadedly connected to its air inlet. Beneficial effects
[0014] This utility model provides a flat vulcanizing machine with a safety device for producing narrow V-belt rubber bands. Compared with the prior art, it has the following advantages:
[0015] 1. This flat vulcanizing machine for producing narrow V-belts with rubber strips and equipped with a safety device, by setting a groove that matches the narrow V-belt, facilitates the placement of the narrow V-belt on the lower mold. When cold water is introduced into the channels near the top of the lower mold and the bottom of the upper mold, the narrow V-belt between the lower and upper molds can be cooled more effectively. Furthermore, the staggered distribution of the channels and grooves can better cool the portion of the narrow V-belt that extends into the groove, thus allowing cooling without opening the mold and improving safety.
[0016] 2. This flat vulcanizing machine for producing narrow V-belt rubber strips with safety devices allows for rapid cooling of the strip by opening the baffles on both sides of the through-slot, aligning the air supply pipe with the through-slot, and then turning on the pump. High-speed airflow enters the through-slot, forming an air duct at the through-hole, thus rapidly cooling the through-slot. Water cooling is used to cool the narrow V-belt rubber strip, while air cooling is used to cool the lower and upper molds, accelerating the cooling process and ensuring efficient cooling. Compared to existing technologies, it eliminates the need to clean moisture from the narrow V-belt rubber strip and the lower mold, reducing production steps. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] See Figures 1-4 This utility model provides the following two technical solutions:
[0024] First embodiment: A flat vulcanizing machine for producing narrow V-belts with rubber bands and a safety device, including a base 1, a fixed plate 2 and a hydraulic telescopic rod 3 on the top of the base 1, a control box 4 on the fixed plate 2 for controlling the electrical components, a movable plate 5 on the hydraulic telescopic rod 3, heating plates 6 on opposite sides of the fixed plate 2 and the movable plate 5, a lower mold 7 connected to the bottom heating plate 6, and an upper mold 8 connected to the top heating plate 6;
[0025] The lower mold 7 is evenly provided with grooves 9, which match the protruding part on the narrow V-belt of the rubber strip. Both the lower mold 7 and the upper mold 8 are connected to water-cooling safety devices.
[0026] To accelerate the cooling of the lower mold 7 and the upper mold 8, through slots 14 can be provided on both the lower mold 7 and the upper mold 8. To avoid the problem that the heating efficiency of the lower mold 7 and the upper mold 8 for the narrow V-belt of the rubber assembly will be slowed down due to the setting of through slots 14, heat transfer plates 15 are evenly arranged in the through slots 14. After the heating plate 6 is heated, the heat entering the through slots 14 can be transferred to the opposite sides of the lower mold 7 and the upper mold 8 by the heat transfer plates 15. To avoid the heat in the through slots 14 being unable to be discharged due to the setting of heat transfer plates 15, through holes 16 are evenly opened on the heat transfer plates 15 to allow airflow to carry away the heat. Air cooling safety devices opposite to the through slots 14 are provided on both the lower mold 7 and the upper mold 8.
[0027] The water-cooled safety device includes channels 10 evenly distributed on the lower mold 7 and the upper mold 8. Connecting pipes 11 are provided on both the front and rear sides of the channels 10. Fixed pipes 12 are connected to the connecting pipes 11 on both the front and rear sides. Mounting pipes 13 are provided on the fixed pipes 12. The mounting pipes 13 on both the front and rear sides are connected to a circulating water cooling device through telescopic pipes. Cold water enters the fixed pipe 12 through the front mounting pipe 13, then enters the channel 10 through the connecting pipe 11, and finally returns to the circulating water cooling device through the rear mounting pipe 13 for cooling and recycling. The use of telescopic pipes to connect the mounting pipes 13 is to prevent the upper mold 8 from being obstructed when it is raised or lowered.
[0028] In order to enable the cooling water in the channel 10 to efficiently cool the narrow V-belt of the rubber strip between the lower mold 7 and the upper mold 8, the channel 10 on the lower mold 7 is set close to the top of the lower mold 7 and the channel 10 on the lower mold 7 is staggered with the groove 9. The channel 10 on the upper mold 8 is set close to the bottom of the upper mold 8. The staggered distribution of the channel 10 and the groove 9 can also better cool the part of the narrow V-belt of the rubber strip that extends into the groove 9, so that cooling can be carried out without opening the mold, thus improving safety.
[0029] The air-cooled safety device includes two baffles 17, which cover both ends of the through groove 14. The bottom of each baffle 17 is connected to an electric telescopic rod 18. The bottom electric telescopic rod 18 is connected to the fixed plate 2, and the top electric telescopic rod 18 is connected to the movable plate 5. The baffles 17 are set to reduce the heat loss in the through groove 14, so as to facilitate the heating and vulcanization of the rubber band narrow V belt.
[0030] An air supply pipe 19 is connected to the left end baffle 17. When not in use, the upper and lower air supply pipes 19 abut against the upper mold 8 and the lower mold 7 respectively. Flexible hoses 20 are evenly connected to the air supply pipes 19. The flexible hoses 20 are connected to the air supply port of the pump 21. The flexible hoses 20 allow the electric telescopic rod 18 to move the air supply pipes 19 without obstruction. The bottom pump 21 is set on the fixed plate 2, and the top pump 21 is set on the movable plate 5. When cooling is required, the electric telescopic rod 18 moves the baffle 17, and the air supply pipes 19 can be aligned with the through groove 14 to supply air.
[0031] The second implementation differs from the first implementation in that: a valve 22 is provided on the air outlet of the pump 21 for easy opening and closing, and a filter cover 23 is threadedly connected to the air inlet of the pump 21 to prevent dust from being sucked in.
[0032] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.
[0033] In use, several rubber strips are placed on the corresponding grooves 9, and then the upper mold 8 and lower mold 7 are closed. Vulcanization is carried out by applying pressure and heating with the heating plate 6. After vulcanization, cooling water is continuously introduced into the channel 10. At the same time, the two bottom baffles 17 are moved downward and the two top baffles 17 are moved upward, thus exposing the through groove 14. At this time, the left side of the through groove 14 is aligned with the air supply pipe 19, and the pump 21 is turned on to supply air into the air supply pipe 19. This causes the high-speed airflow to flow to the right through the through hole 16, effectively cooling the lower mold 7 and the upper mold 8. The cooling water in the channel 10 cools the rubber strips. As the lower mold 7 and the upper mold 8 cool down, the rubber strips are also cooled. Therefore, cooling can be carried out without opening the mold, and moisture is avoided on the rubber strips and the lower mold 7.
