Sample inlet mechanism capable of being applied to sample product packaging machine

Abstract

The invention discloses a sample material inlet mechanism which can be used on a baler for sampling and preparing products, comprising a base and an unloading cylinder sheathed on the base, and the inner diameter of the outlet of the unloading cylinder is smaller than that of the packaging container for sampling and preparing products placed on the baler The inner diameter of the opening at the top and the outer diameter of the outlet of the unloading barrel are larger than the inner diameter of the opening at the top of the packaging container for sampling and preparing products placed on the baler, and the outer side of the unloading barrel is connected with a driving mechanism that can drive it to move up and down. The invention has the advantages of simple structure, simple control process, high operation reliability, low failure rate, tightness, and can avoid adhesion and dust.

Description

technical field [0001] The invention belongs to the field of packaging machinery for sampling and preparing products, and in particular relates to a sample material inlet mechanism that can be used on a packing machine. Background technique [0002] At present, when domestic mineral material (such as coal mine) sampling and processing manufacturers purchase ready-made packing machines and inkjet printers from food machinery manufacturers when packaging sample products, these outsourced packing machines and inkjet printers The machine was originally designed for the packaging of the food industry. After it was applied to the sampling industry, due to changes in environmental conditions, it was difficult to use normally, and the failure rate was very high. negative impact on stable operation. [0003] There are two main types of balers on the market: plastic film balers and woven bag balers. [0004] The plastic film baler has the following disadvantages: ①Due to the relativ...

Problems solved by technology

[0004] The plastic film baler has the following disadvantages: ①Due to the relatively low strength of the plastic bag, a sample bag can only hold a few kilograms of samples, so generally it can only be used for packaging samples of 5kg or less; ②The site conditions are harsh, the dust is heavy, and it is easy to The length of the roll bag is wrong, often due to the slipping of the dragging roller, the sample bag is much shorter than the set bag length, and the material cannot be loaded; ③Due to dust, the seal cannot be successfully sealed after the dust is stuck on the heat-sealed part; ④The sensor on the baler There are also many, such as photoelectric sensors for measuring the position of plastic bags, servo controllers, etc., which are prone to false signals in a high-dust environment, causing the equipment to fail to work normally

The inkjet printer used in conjunction with the plastic film baler will also have the following disadvantages: ①The inkjet printer has relatively high requirements for the use environment. In terms of ambient temperature, the normal ink ejection cannot be guaranteed if the ambient temperature is lower than 5°C; In a dusty environment, the nozzle is easily blocked, and the nozzle needs to be cleaned manually with alcohol every day, which is cumbersome to operate; ③The inkjet printer sprays out numbers or letters, and cannot spray out barcodes and other information that can be automatically recognized by the machine

[0005] The woven bag baler has the following disadvantages: ①It is necessary to manually place the IC card in the woven bag before going to work every day, and put dozens of sample bags into the bag slot, which is relatively labor-intensive; ②The pneumatic suction cup sucks the woven bag There are often cases where the bag cannot be sucked, resulting in the failure of the bag; ③The pneumatic suction cup cannot be sucked when it sucks the woven bag to open the bag mouth, resulting in the bag opening being unable to open; ④When the woven bag is stitched by the sewing machine, the sewing machine ⑤After the woven bag is stitched, the thread cutting fails when the suture thread is automatically cut off, which leads to the failure of the next sample bag to be sewed normally; , making it difficult to maintain the level of the woven bag, causing the suture line to be not straight, which in turn causes part of the woven bag to fail to be sutured, resulting in suture failure

[0007] At present, the sample material inlet on the baler (sample retaining machine) in the sample collection industry generally enters the sample packaging container through a cylinder, but there is often a gap between the sample packaging container and the cylinder; when the material When the moisture content is small, it is particularly prone to dusting; when the moisture content of the material is large, the inner wall of the feeding cylinder is likely to adhere to the material, resulting in clogging, or mixing of different batches of materials, and the actual state of the sample is difficult. reflect objectively and truthfully
