Description

Technical Field

[0001] This utility model relates to the technical field of elevator belt processing equipment, and in particular to an elevator belt punching device. Background Technology

[0002] Elevator belts are key components used for vertical or inclined material conveying. By attaching and fixing elevator buckets to the surface, blocky, granular, or powdery materials can be lifted from a low position to a high position. They have advantages such as low noise, acid and alkali resistance, and wear resistance. When installing buckets on the surface of the elevator belt, it is necessary to first drill holes in the belt surface. However, existing elevator belt punching devices generally have the problem of low punching quality and precision.

[0003] For example, Chinese utility model patent CN118990682A discloses a punching device for belt processing, including a belt punching machine fixed above a punching table. Although this solution achieves efficient semi-automatic punching of belts by quickly feeding the belt to the lower punch seat and punch head of the belt punching machine for one-time forming punching, and then feeding it to the edge of the punching table by a clamping mechanism and being lifted by an upper structure for removal by the worker, thus improving the efficiency of belt punching, before the belt is punched, its surface is often covered with foreign matter such as adhesives, dust, debris, and solid particles. If the belt is not treated before being directly fed into the punching head for punching, it may result in low punching accuracy or belt deformation.

[0004] In view of this, a punching device for elevator belts that can solve the above problems is proposed. Utility Model Content

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0016] Example: Please combine Figure 1 and Figure 4 As shown, a hoist belt punching device of this embodiment includes a base 1, and a lower die base 9 is installed on the upper side of the base 1. In this embodiment, the upper side of the lower die base 9 is provided with a slot to facilitate the falling of the stamped iron sheet into the slot for unified collection and management. Please combine Figure 4 and Figure 5 As shown, a pretreatment table 11 is fixedly connected to one side of the lower mold base 9. A feeding channel 10 is provided on one side of the pretreatment table 11. It should be noted that the feeding channel 10 and the upper surface of the lower mold base 9 are on the same horizontal plane, that is, the belt entering from the feeding channel 10 can flow directly through the upper surface of the lower mold base 9. Please combine Figure 6 As shown, the pretreatment table 11 has an oil tank 23 inside, and the feed channel 10 passes through the middle of the oil tank 23. In this embodiment, the oil tank 23 contains a belt-specific detergent, such as SK353.

[0017] Please combine Figure 5 As shown, the circulating supply mechanism includes a pump body 22 installed on one side of the pretreatment table 11. The pump body 22 is located on the side of the pretreatment table 11 away from the second servo motor 18. The inlet of the pump body 22 is connected to the bottom of the oil tank 23, and the outlet of the pump body 22 is connected to the return pipe 21. A nozzle 25 is installed on the top of the oil tank 23. One end of the nozzle 25 is connected to the upper end of the return pipe 21, and the nozzle 25 is located above the brush roller 24.

[0018] Please combine Figure 6 As shown, the drying and heating mechanism includes a drying chamber 26 opened inside the pretreatment table 11, a drying pipe 19 installed on the upper side of the drying chamber 26, a fan 16 installed on one side of the drying chamber 26, and a ventilation slot 20 opened on the other side of the drying chamber 26. It should be noted that the drying chamber 26 in this embodiment plays two roles. In addition to drying the moisture on the surface of the belt, it also needs to heat the belt for pretreatment to facilitate subsequent stamping. Therefore, the width of the drying chamber 26 and the power of the drying tube 19 in this embodiment need to be set according to the actual scenario. Please combine Figure 1 As shown, the punching mechanism includes a fixed plate 2 fixedly connected to the upper side of the base 1. Two slides 5 are fixedly connected to the side of the fixed plate 2 near the lower die base 9. A push plate 6 is slidably connected to the two slides 5. A limit station 7 is fixedly connected to the lower side of the push plate 6. In this embodiment, two punch heads 12 are fixedly connected to the lower side of the limiting platform 7. In other embodiments, different numbers and specifications of punch heads 12 can be set according to the belt opening layout requirements and the opening hole type, for example, punching holes in rows. Please combine Figure 1 As shown, a pressure plate positioning mechanism is provided below the limiting platform 7, and a push plate driving mechanism that moves the push plate 6 up and down is provided on one side of the fixed plate 2.

[0019] Please combine Figure 2As shown, the pressure plate positioning mechanism includes two slide rods 14 that are slidably connected to the limiting platform 7. The lower ends of the two slide rods 14 are fixedly connected to the pressure plate 8. A spring 15 is sleeved on the outside of each slide rod 14. The upper end of each spring 15 is fixedly connected to the lower side of the limiting platform 7, and the lower end of each spring 15 is fixedly connected to the upper side of the pressure plate 8. Each punch head 12 is slidably connected to the pressure plate 8.

[0020] Please combine Figure 1 As shown, the push plate drive mechanism includes a turntable 4 rotatably connected to one side of the fixed plate 2. A crank connecting plate 13 is rotatably connected to the eccentric position of the turntable 4. One end of the crank connecting plate 13 is rotatably connected to one side of the push plate 6. A first servo motor 3 is installed on the side of the fixed plate 2 away from the turntable 4. The output end of the first servo motor 3 is connected to one side of the turntable 4.

[0021] The implementation principle of the belt punching device for a hoist in this embodiment is as follows: The belt to be punched is fed from the feeding channel 10 into the pretreatment table 11 and the lower die base 9. The pump body 22 and the second servo motor 18 are started, driving the brush roller 24 to rotate. The pump body 22 draws cleaning liquid from the oil tank 23 and injects it into the nozzle 25 through the return pipe 21, spraying the cleaning liquid onto the brush roller 24, thereby thoroughly cleaning the surface of the belt. The cleaned liquid falls back into the oil tank 23 along both sides of the belt. The cleaned belt enters the drying chamber 26 and is heated by the drying pipe 19. The fan 16 accelerates the airflow and exhausts the gas from the ventilation slot 20. After being cleaned and dried, the belt travels to the lower mold base 9 and pauses intermittently. The first servo motor 3 starts and drives the turntable 4 to rotate. Under the pushing action of the crank connecting plate 13, the push plate 6 is pushed to slide along the slide table 5, thereby pushing the limit table 7 down. Due to the action of the slide rod 14 and the spring 15, the pressure plate 8 will contact the upper surface of the belt before the punch head 12. The spring 15 is compressed and deformed, and the punch head 12 slides down along the inner side of the pressure plate 8, thereby realizing the function of the punch head 12 punching the belt.

[0022] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
