Description

Technical Field

[0001] This utility model relates to a sampling and weighing trolley for tobacco leaf re-drying structure, belonging to the technical field of tobacco leaf re-drying sampling equipment. Background Technology

[0002] In the re-drying and processing of tobacco leaves, quality control is of paramount importance. Due to the natural differences in origin, variety, part of the plant, and grade of the raw tobacco, and the dynamic changes in parameters such as flow rate, temperature, humidity, air separation efficiency, and drying rate during processing, the materials (leaves and stems) at different times and locations on the production line exhibit unevenness in key physical indicators (such as leaf structure, moisture content, leaf content in stems, and stem content in leaves) and chemical indicators (such as the content of major chemical components).

[0003] This non-uniformity presents a significant challenge to quality assessment: Unable to perform full inspection: It is impossible to perform 100% inspection on batches of materials weighing several tons or even tens of tons; A key challenge is how to obtain a small sample from a large quantity of uneven products that can truly reflect the average quality and quality fluctuations of the entire batch of materials, which is crucial for quality assessment.

[0004] Therefore, sampling becomes the bridge connecting the production process and quality evaluation, and is the most basic and crucial link in the leaf re-drying quality assurance system. The representativeness, accuracy, and timeliness of sampling guide operators in adjusting process parameters and determining quality grades. Traditional sampling methods mainly rely on manual labor, involving fixed-point, timed "grabbing" or "intercepting" at specific locations on the production line (such as the packaging machine exit). While this method is simple, it has significant drawbacks: (1) There are two sampling locations for the tobacco leaf structure sampling before and after re-drying. The manual sampling box and weighing equipment are used to go to the location before re-drying to collect and weigh the sample. After that, the sample is brought back to the testing room. The manual sampling box and weighing equipment are used to go to the location after re-drying to collect and weigh the sample. After that, the sample is brought back to the testing room. The operation efficiency is low and it is time-consuming and labor-intensive. (2) The existing sampling and weighing method involves manually holding a sampling box to sample tobacco leaves, visually estimating the sample weight, and then moving it to a nearby weighing device for weighing. This method has the problem of low compliance rate of visually estimated sample weight. If the weight does not meet the standard after visual sampling, tobacco leaves cannot be manually added or reduced, and all leaves must be recycled and the sampling must start from scratch. At the same time, manual sampling requires repeated movement between the sampling location before re-drying and the quality inspection room, and between the sampling location after re-drying and the quality inspection room. It is not possible to complete the sampling before and after re-drying at one time, resulting in long sampling time and labor-intensive problems. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a sampling and weighing trolley for tobacco leaf re-drying to at least solve the problems mentioned in the background art.

[0006] The objective of this utility model is achieved through the following technical solution: A sampling and weighing trolley for tobacco re-drying leaves includes a trolley body with multiple layers of racks arranged from bottom to top on the trolley body, and an electronic scale is installed on the top rack; each rack has a leaf sampling box.

[0007] Furthermore, the placement rack has at least two layers.

[0008] Furthermore, the multi-layered storage rack can be a single-piece structure or a modular structure.

[0009] Furthermore, the trolley body includes a base plate, which is a rectangular plate structure. Universal wheels are provided at the bottom of the base plate, and a handle is provided on one side of the base plate.

[0010] Furthermore, the placement rack includes a placement plate with a structure similar to the base plate, and support rods are provided at the four corners of the top of the placement plate. The upper ends of the support rods are connected together by connecting rods.

[0011] Furthermore, the blade sampling box includes a blade structure sampling box before re-baking and a blade structure sampling box after baking.

[0012] Furthermore, the leaf sampling box includes a box body adapted to the placement rack, with flanges on each side of the top of the box body that can be placed on the connecting rod, and a lid that can be opened is provided in the middle of the top surface of the box body.

[0013] Furthermore, a slot is provided at the top of the support rod on the rear side of the lowest shelf, and the handle is inserted and connected to the support rod.

[0014] Furthermore, the electronic scale includes a scale body and a display screen connected to the scale body. The scale body is fixed to the center of the top surface of the top shelf by a magnetic structure and a suction cup structure.

[0015] Compared with the prior art, the beneficial effects of this utility model are: This utility model is convenient to use, easy to operate, has good stability and high reliability. By setting up a multi-layer placement rack on the trolley body, with multiple leaf sampling boxes on the placement rack, and adding an electronic scale on the top placement rack, it can complete the sampling and weighing of leaf structure before and after re-drying in one go. The sampling efficiency is high, effectively reducing the number of repeated samplings. Compared with manual hand-held sampling boxes, it is more convenient and labor-saving. The electronic scale displays the weight of the tobacco leaf structure sample in real time, which is more accurate than manual visual weight measurement.

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 scope of protection of the present utility model.

[0020] like Figure 1 As shown, the first embodiment of this utility model provides a tobacco leaf re-drying leaf structure sampling and weighing trolley, including a trolley body 1, with multiple layers of placement racks 2 arranged from bottom to top on the trolley body 1, and an electronic scale 3 arranged on the top layer of placement rack 2; and a leaf sampling box 4 arranged on each layer of placement rack 2.

[0021] The trolley body 1 includes a base plate 101, which is a rectangular plate structure. A caster wheel 102 is provided at the bottom of the base plate 101, and a handle 103 is provided on one side of the base plate 101.

[0022] The placement rack 2 has at least two layers.

[0023] The multi-layered shelf 2 is either an integrated structure or a modular structure.

[0024] The placement rack 2 includes a placement plate 201 with a structure similar to the base plate 101. Support rods 202 are provided at the four corners of the top of the placement plate 201, and the upper ends of the support rods 202 are connected together by connecting rods 203.

[0025] Specifically, in the integrated structure, the lower end of the support rod 202 of each layer of the shelf 2 is welded and fixed to the placement plate 201, and the upper end is welded and fixed to the connecting rod 203. Adjacent layers of shelves 2 are fixed together by welding or bolting. This structure has good stability and high connection reliability.

[0026] In the aforementioned modular structure, the lower end of the support rod 202 of each shelf 2 is inserted and fixedly connected to the shelf plate 201, and the upper end is inserted and connected to the connecting rod 203. Adjacent shelves 2 are also fixedly connected together via an insertion structure. This structure allows for flexible assembly and adjustment of shelf height, offering good adaptability.

[0027] The blade sampling box 4 includes a blade structure sampling box before re-baking and a blade structure sampling box after baking.

[0028] The leaf sampling box 4 includes a box body 401 that is adapted to the placement rack 2. Each side of the top of the box body 401 is provided with a flange 402 that can be placed on the connecting rod 203. The top surface of the box body 401 is provided with an openable box cover 403.

[0029] A slot is provided at the top of the support rod 202 on the rear side of the bottom shelf, and the handle 103 is inserted and connected to the support rod 202.

[0030] The electronic scale 3 is existing technology, and it includes a scale body 301 and a display screen 302 connected to the scale body 301. The scale body 301 is fixed to the center of the top surface of the top shelf 2 by a magnetic structure, suction cup structure or other detachable connection structure.

[0031] Working principle and process of the device: (1) The tobacco leaf discharge port 5 of the pre-drying production line and the tobacco leaf discharge port of the post-drying production line have a fixed height in the re-drying production site. During use, the pre-drying leaf structure sampling box is first placed on the electronic scale 3 of the top shelf 2, and the weight of the pre-drying leaf structure sampling box is tare or read. (2) Push the trolley directly to the bottom of the discharge port before re-drying, open the sampling box cover 401 to take samples: After pressing the production line discharge switch, the tobacco leaves at the discharge port fall directly into the leaf structure sampling box before re-drying. The electronic scale 2 displays the sample weight in real time. After the weight reaches the standard, immediately close the discharge switch at this position to complete the sampling at the position before re-drying. After completing the sampling before re-baking, the upper and lower layers of the pre-baking blade structure sampling box and the post-baking blade structure sampling box are swapped, and the above steps (1) and (2) are repeated to complete the post-baking sampling.

[0032] This device solves the problems of inaccurate visual weight estimation when manually holding the sampling box below the discharge port and the inability to manually complete the sampling and weighing of the blade structure at two locations at one time. It has high operating efficiency and saves time and effort.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to restrict the present utility model in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments without departing from the technical solution of the present utility model and based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
