Description

Technical Field

[0001] This utility model relates to the field of conveyor equipment technology, specifically a fast-return conveyor. Background Technology

[0002] Quick-return conveyors are mainly used for conveying food materials containing seasonings or fragile items. They are suitable for long-distance conveying (the longest trough can reach 20 meters) and can convey materials weighing up to 15 tons per hour (such as monosodium glutamate). Since only sheet metal troughs are used for conveying materials, cleaning is easier and faster when products need to be changed. This application utilizes the principle of quick-return characteristics, allowing materials to be conveyed forward by inertia. The fast-forward and slow-reverse motion ensures that the materials are conveyed smoothly and without vibration. Compared with traditional vibrating conveyors, this feeding method reduces the material breakage rate and allows for longer conveying distances. It also reduces power consumption by 30%-40% compared with ordinary conveyors. However, existing belt conveyors have insufficient cooling efficiency when conveying high-temperature materials, and conventional belt conveyors have many unsanitary corners, and there is a risk of grease getting into the belt. Vibrating conveyors are usually noisy and have a high vibration frequency, which is not conducive to conveying fragile materials. Therefore, there is an urgent need for a quick-return conveyor to solve the above-mentioned problems. Utility Model Content

[0003] The purpose of this invention is to provide a fast-return conveyor to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a fast-return conveyor, comprising a support frame, a three-phase asynchronous motor disposed at the center of the side end face of the frame, and a drive synchronous pulley disposed at the output end of the three-phase asynchronous motor; a limit bracket disposed near the center of the upper end face of the frame, and a counterweight bracket disposed near the outer side of the upper end face of the frame.

[0005] A transmission device is provided, which is located at the middle of the inner end face of the frame. A driven synchronous pulley is provided at the output end of the transmission device. The driving synchronous pulley and the driven synchronous pulley are meshed and connected by a synchronous belt. The transmission device is used for transmission.

[0006] A material guide trough is disposed on the upper part of the limiting bracket, and a counterweight plate is disposed on the upper part of the counterweight bracket.

[0007] Preferably, the transmission device includes a limiting bracket for support. A first herringbone toothed synchronous pulley, a second herringbone toothed synchronous pulley, a third herringbone toothed synchronous pulley, and a fourth herringbone toothed synchronous pulley are arranged clockwise at the front of the limiting bracket. A drive shaft is provided on the inner end face of the first herringbone toothed synchronous pulley. The first herringbone toothed synchronous pulley, the second herringbone toothed synchronous pulley, the third herringbone toothed synchronous pulley, and the fourth herringbone toothed synchronous pulley are synchronously driven by a herringbone synchronous belt. A first crank is provided on one side of the inner end face of the limiting bracket, and a second crank is provided on the other side of the inner end face of the limiting bracket.

[0008] Preferably, the three-phase asynchronous motor transmits power to the drive shaft through the active synchronous pulley, the synchronous belt, and the driven synchronous pulley, which can improve the stability of subsequent power transmission.

[0009] Preferably, the central shaft of the second herringbone toothed synchronous pulley is a crankshaft, which facilitates providing sufficient power to the first and second cranks for reciprocating motion.

[0010] Preferably, the crankshaft converts the rotational motion into linear motion via the first crank and the second crank, which can improve the stability of the subsequent material guide trough during reciprocating oscillation and improve the material conveying efficiency.

[0011] Preferably, the lateral movement output by the first crank and the second crank causes the limiting bracket and the counterweight bracket to swing laterally, which can effectively improve the efficiency and stability of the equipment in conveying materials.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting up a transmission device, enables the crankshaft inside the second herringbone synchronous pulley to convert the rotational motion into linear motion via the first and second cranks. The lateral movement output by the first and second cranks pushes the limit bracket and the counterweight bracket to move back to their original positions. At the same time, the guide trough connected to the limit bracket and the counterweight plate connected to the counterweight bracket move in opposite directions, and the torques cancel each other out. This ensures that the entire device will not vibrate or move when placed on the ground, effectively reducing the noise of the conveyor during material feeding and improving the material conveying efficiency.

[0014] 2. The material of the material guide trough of this utility model is 304 stainless steel. For high-temperature materials, it can cool the materials to room temperature faster than belt conveyors and facilitate subsequent cleaning, thus improving the practical performance of the equipment.

Detailed Implementation

[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] Please see Figure 1-6 This utility model provides an embodiment of a fast-return conveyor, including a frame 1 for support, a three-phase asynchronous motor 7 disposed at the middle of the side end face of the frame 1, and a drive synchronous pulley 10 disposed at the output end of the three-phase asynchronous motor 7, a limit bracket 3 disposed near the middle of the upper end face of the frame 1, and a counterweight bracket 4 disposed near the outer side of the upper end face of the frame 1.

[0024] Transmission device 2 is located at the middle of the inner end face of frame 1. A driven synchronous pulley 8 is provided at the output end of transmission device 2. The driving synchronous pulley 10 and the driven synchronous pulley 8 are meshed and connected by a synchronous belt 9. Transmission device 2 is used for transmission.

[0025] The material guide trough 6 is located on the upper part of the limiting bracket 3, and a counterweight plate 5 is located on the upper part of the counterweight bracket 4.

[0026] The transmission device 2 includes a limiting bracket 2.9 for support. A first herringbone toothed synchronous pulley 2.2, a second herringbone toothed synchronous pulley 2.4, a third herringbone toothed synchronous pulley 2.5, and a fourth herringbone toothed synchronous pulley 2.6 are arranged clockwise at the front of the limiting bracket 2.9. A drive shaft 2.1 is arranged on the inner end face of the first herringbone toothed synchronous pulley 2.2. The first herringbone toothed synchronous pulley 2.2, the second herringbone toothed synchronous pulley 2.4, the third herringbone toothed synchronous pulley 2.5, and the fourth herringbone toothed synchronous pulley 2.6 are synchronously driven by a herringbone synchronous belt 2.3. A first crank 2.7 is arranged on one side of the inner end face of the limiting bracket 2.9, and a second crank 2.8 is arranged on the other side of the inner end face of the limiting bracket 2.9.

[0027] The three-phase asynchronous motor 7 transmits power to the drive shaft 2.1 through the active synchronous pulley 10, the synchronous belt 9, and the driven synchronous pulley 8, which can improve the stability of subsequent power transmission.

[0028] The central axis of the second herringbone toothed synchronous pulley 2.4 is the crankshaft, which facilitates providing sufficient power to the first crank 2.7 and the second crank 2.8 for reciprocating motion.

[0029] The crankshaft converts the rotational motion into linear motion via the first crank 2.7 and the second crank 2.8, which can improve the stability of the reciprocating oscillation of the subsequent material guide trough 6 and improve the material conveying efficiency.

[0030] The lateral movement of the first crank 2.7 and the second crank 2.8 outputs the lateral movement of the limit bracket 3 and the counterweight bracket 4, which can effectively improve the efficiency and stability of the equipment for subsequent material conveying.

[0031] Working Principle: During operation, the three-phase asynchronous motor 7 first outputs power to the drive shaft 2.1 via the driven synchronous belt pulley 8. The drive shaft 2.1 then drives the herringbone toothed synchronous pulley 2.2. The first herringbone toothed synchronous pulley 2.2, the second herringbone toothed synchronous pulley 2.4, the third herringbone toothed synchronous pulley 2.5, and the fourth herringbone toothed synchronous pulley 2.6, through the herringbone synchronous belt 2.3, transmit the uniformly rotating power to the second herringbone toothed synchronous pulley 2.4 via a specific structure. The central axis of the second herringbone toothed synchronous pulley 2.4 is a crankshaft. Rotating the crankshaft converts the rotational motion into linear motion via the first crank 2.7 and the second crank 2.8. Simultaneously, due to the limiting bracket 3... The first crank 2.7 and the second crank 2.8, connected to the guide trough 6 via sheet metal parts, push the limit bracket 3 and the counterweight bracket 4 with lateral movement. The counterweight plate 5 is installed on the counterweight bracket 4, causing the guide trough 6 connected to the limit bracket 3 and the counterweight plate 5 connected to the counterweight bracket 4 to move in opposite directions. The torques cancel each other out, so that the entire equipment will not vibrate or move when placed on the ground, improving the quietness and stability of the equipment operation. At the same time, the three-phase asynchronous motor 7 can use 0.75kw, 1.5kw, or 2.2kw motors, depending on the weight of the guide trough 6 being driven. Changing the motor model can save more electricity if the overall size of the equipment remains unchanged.
