Description

Technical Field

[0001] The utility model relates to the technical field of conveying devices, in particular to a material conveying device for freeze-drying equipment. Background Art

[0002] Freeze drying is to freeze a substance containing a large amount of water into a solid state by cooling it down in advance, and then sublimate the solid water directly under vacuum conditions, while the substance itself remains in the ice shelf when frozen, so its volume remains unchanged after drying. Freeze drying is carried out at low temperatures, so it is particularly suitable for many heat-sensitive substances.

[0003] In the existing technology, when a factory is producing freeze-drying equipment, it is necessary to clean the raw materials, dry them initially and then spread them out to ensure uniform and rapid cooling, which makes the process before freeze-drying complicated and seriously restricts the freeze-drying efficiency.

[0004] Therefore, it is necessary to invent a material conveying device for freeze drying equipment to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a material conveying device for freeze-drying equipment, so as to solve the problem that in the process of freeze-drying equipment production, raw materials need to be cleaned, preliminarily dried and then spread out to ensure uniform and rapid cooling, which leads to complicated procedures before freeze-drying and seriously restricts the freeze-drying efficiency.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a material conveying device for freeze-drying equipment, comprising a conveying box body, a conveyor belt is arranged inside the conveying box body, a storage tray is arranged on the upper side of the conveyor belt, a support rod is fixedly connected to the upper side of the storage tray, two groups of abutment blocks are fixedly connected to the upper surface of the support rod, a cleaning box body and a drying box body are fixedly connected to the upper side of the conveying box body, a cleaning mechanism is arranged inside the cleaning box body, the cleaning mechanism comprises a water inlet pipe, a high-pressure nozzle, a transmission shaft, an eccentric wheel, and a progressive motor, and the side surface of the eccentric wheel is tightly abutted against the upper end of the abutment block.

[0007] By adopting the above technical solution, the conveyor belt is used to transport the placement tray and materials to the inside of the freezing chamber. During the transportation process, the staff directly pours the materials onto the surface of the placement tray, and the eccentric wheel is driven by the progressive motor to rotate to flatten the materials on the surface of the placement tray. The high-pressure nozzle flushes and cleans the materials on the surface of the placement tray, thereby achieving cleaning during the transportation process and improving the freeze-drying preparation efficiency.

[0010] By adopting the above technical solution, the output end of the progressive motor drives the transmission shaft to rotate, and the transmission shaft drives the eccentric wheel to rotate.

[0011] Optionally, the water inlet pipe is fixedly connected to the top wall of the cleaning box, and the lower end of the water inlet pipe is fixedly connected to a transmission main pipe.

[0012] Optionally, a plurality of groups of flow distribution pipes are fixedly connected to the side of the transmission main pipe, and the high-pressure nozzle is fixedly connected to an end of the flow distribution pipe away from the transmission main pipe.

[0013] By adopting the above technical solution, the water inlet pipe transports the water source to the inside of the high-pressure nozzle, and the high-pressure nozzle sprays the water downward to wash the materials on the surface of the storage tray.

[0015] By adopting the above technical solution, when the eccentric wheel rotates, its long side presses the placement plate downward. When the eccentric wheel rotates to the short side, the vibration spring pushes the placement plate upward, causing the placement plate to vibrate up and down. During the vibration, the material is turned over to achieve all-round cleaning, and the material is spread flat on the surface of the placement plate.

[0016] Optionally, a plurality of groups of clamping plates are fixedly connected to the upper surface of the conveyor belt, and clamping grooves are provided on the upper surfaces of the clamping plates, and the clamping strips are clamped inside the clamping grooves.

[0017] By adopting the above technical solution, the staff will clamp the card strip on one side of the card slot, and then push the placement tray to the upper side of the conveyor belt to improve the stability of the placement tray during transportation. When it reaches the freeze-drying room, the tray will be removed and placed on the rack for freeze-drying.

[0018] Optionally, a plurality of drainage holes are provided on the side wall of the storage tray.

[0019] By adopting the above technical solution, the drainage hole is used to discharge the water in the cleaning process to the outside.

[0031] Among them, during the production process, the staff first clamps the clamping strip 36 inside the clamping groove 13, and pushes the placement tray 3 to the upper side of the conveyor belt 11. Next, the staff pours a certain amount of material directly onto the surface of the placement tray 3. At this time, the conveyor belt 11 transports the material to the inside of the freeze-drying chamber. When the material is transported to the inside of the cleaning box 2, the cleaning mechanism cleans the material on the surface of the placement tray 3 and flattens the material onto the surface of the placement tray 3.
