Description

Technical Field

[0001] The invention belongs to the technical field of refrigerated packaging, and in particular relates to a 0-4° environmental laminar flow workbench. Background Art

[0002] Packaging has two characteristics: subordination and commodity nature. Packaging is an accessory to its contents; commodity packaging is a special commodity attached to the commodities contained therein, which has value and use value; at the same time, it is an important means to realize the value and use value of the commodities contained therein. When packaging some products, the packaging and bagging steps need to be completed in a cold storage environment. Due to the physical properties of the product, the product may become fluid and difficult to package when the temperature is high.

[0003] The current mainstream packaging method requires workers to complete the packaging work in a cold storage with a lower temperature. Not only do they need to wear thick clothes for cold protection, but they are also very likely to get frostbite when they are not well protected or work for a long time. In addition, the packaging process is limited by the thick clothing, which can easily affect the packaging operation and is inconvenient to use.

[0004] Based on the above-mentioned situation, we found that it is difficult to avoid the above problems with the low-temperature packaging workbench of the existing technology. Therefore, we proposed a 0-4° environmental laminar flow workbench in which personnel can be located outside the cold storage, reducing the workload on workers and the possibility of frostbite. It can also ensure the quality of the packaging process while ensuring the packaging environment. Summary of the invention

[0005] The purpose of the present invention is to provide an existing 0-4° environmental laminar flow workbench, which has the advantages that personnel can be located outside the cold storage, reducing the workload on the workers and reducing the possibility of frostbite, and can ensure the quality of the packaging process while ensuring the packaging environment.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: a 0-4° environmental laminar flow workbench, comprising a horizontal bracket and a vertical bracket, the vertical bracket is bolted at the chamfer of the horizontal bracket, a workbench desktop is bolted on the inner side of the horizontal bracket, a box plate is bolted on the inner side of the vertical bracket, a first item transfer tempered glass door is installed on the inner side of the front box plate and the rear box plate, a glove slot is provided on the inner side of the first item transfer tempered glass door, a top bracket is bolted on the top of the vertical bracket, a chassis is bolted on the top of the top bracket, a static pressure box is installed on the inner side of the chassis, a fan is installed on the top of the inner wall of the static pressure box, a high-efficiency filter is installed on the bottom of the inner side of the static pressure box, isolation frames are bolted on the front and rear sides of the top of the horizontal bracket, and a second item transfer tempered glass door is installed between the opposite sides of the two isolation frames and on the side of the isolation frame close to the right vertical bracket.

[0007] By adopting the above technical scheme, a sealed cold storage space is formed by setting a horizontal bracket to cooperate with the vertical bracket and the box plate, and the packaged products are placed and operated through the workbench desktop inside the horizontal bracket. The first item transfer tempered glass door is usually in a closed state and cooperates with the box plate to form a whole. The staff can insert their hands into the glove slots to fix the work gloves and process the items through the work gloves. The human body does not need to be in the cold storage environment, thereby avoiding frostbite of the personnel. Only the hands need to be kept warm and protected. Therefore, the clothing is relatively not heavy, and the product can be packaged more conveniently. The top bracket is coordinated with the chassis and the static pressure box to install the fan and ventilate the operating space. The high-efficiency filter is used to make the airflow cleaner. The isolation rack and the second item transfer tempered glass door are used for uninterrupted operation. While the personnel are processing on the workbench desktop, the feeding personnel can open the second item transfer tempered glass door on the front side and put in the products to be packaged. After the packaging is completed, the staff uses work gloves to open the second item transfer tempered glass door on the left side from inside the working environment and completes the switching between packaged items and unpackaged items, which effectively improves work efficiency.

[0008] The present invention is further configured as follows: the workbench tabletop is made of a stainless steel brushed plate with mesh holes, and a concave is provided on the front side of the front box plate.

[0009] By adopting the above technical solution, the workbench table top is made of a stainless steel brushed plate with mesh holes, which has sufficient strength and has the effects of lightweight, constant temperature and ventilation. The concave recess can facilitate the placement of the workers' legs, making it more comfortable for the workers to work at their workstations.

[0010] The present invention is further configured as follows: the first article transfer tempered glass door is configured to rotate horizontally to open, the second article transfer tempered glass door is configured to rotate vertically to open, and sealing strips are provided on the outer sides of the first article transfer tempered glass door and the second article transfer tempered glass door.

[0011] By adopting the above technical solution, by setting the first item transfer tempered glass door to rotate horizontally and open, it can be more convenient to change work gloves, and the second item transfer tempered glass door to rotate vertically and open can facilitate personnel to replace products. The set sealing strip can prevent poor structural sealing from causing temperature failure or impurities to enter.

[0012] The present invention is further configured as follows: a foot cup is bolted to the bottom chamfer of the vertical bracket, and the foot cup is made of stainless steel.

[0013] By adopting the above technical solution and providing the foot cup, the structure can be placed stably and has sufficient strength.

[0014] The present invention is further configured as follows: a lighting lamp is installed at the bottom of the inner side of the chassis, and a flow equalizing membrane is provided at the bottom of the chassis.

[0015] By adopting the above technical solution, the lighting can be provided to provide supplementary lighting for the working environment, and the flow equalizing membrane can be combined with the high-efficiency filter to further improve the filtering effect.

[0016] The present invention is further configured as follows: a pressure differential gauge and a controller panel are installed on the front side of the chassis.

[0017] By adopting the above technical solution, the operating environment can be easily controlled by setting a pressure differential gauge and a controller panel, and parameters such as pressure differential can be monitored at the same time.

[0018] The present invention is further configured as follows: the detection range of the differential pressure gauge is 0-500Pa, and the flow equalizing membrane is set to 200 meshes.

[0019] By adopting the above technical solution, a 0-500Pa differential pressure gauge can be set to facilitate monitoring of the pressure difference within the normal pressure range. The flow equalizing membrane can further block the filtered airflow to reduce impurities therein.

[0020] The present invention is further configured such that: the front right side and the rear side of the chassis are both provided with return air holes.

[0021] By adopting the above technical solution and providing the return air holes, the flow of air can be easily guided and circulated.

[0022] The present invention is further configured as follows: a glove is installed on the inner side of the glove slot, a connection between the glove and the glove slot is configured as an ellipse matching the shape of the glove slot, and the glove is made of chlorosulfonated polyethylene material.

[0023] By adopting the above technical solution, the work gloves made of chlorosulfonated polyethylene material have sufficient strength and stable properties to work normally at different temperatures, and the elliptical glove groove can easily fit the normal movement of the arms and wrists of the personnel.

[0024] The present invention is further configured as follows: the internal temperature of the box body plate is constant at 0-4°C, the external environment temperature needs to be constant at 20°C, and the external environment humidity is 30%.

[0025] By adopting the above technical solution, the temperature is set to be constant at 0-4°C to match the temperature at which the product will not liquefy. The external environment temperature needs to be constant at 20°C and the external environment humidity is 30% to avoid water mist on the glass surface, which makes it difficult to observe.

[0026] In summary, the present invention has the following beneficial effects:

The first item transfer tempered glass door is usually in a closed state and forms a whole with the box plate. The staff can insert their hands into the glove slots to fix the work gloves and use the work gloves to process the items. The human body does not need to be in the cold storage environment, thereby avoiding frostbite. Only the hands need to be kept warm, so the clothing is relatively not heavy, and the product can be packaged more conveniently. The rack cooperates with the chassis and the static pressure box to install the fan and ventilate the operating space. The high-efficiency filter is set to make the airflow cleaner. The isolation rack and the second object transfer tempered glass door are used for uninterrupted operation. While the personnel are processing on the workbench desktop, the feeding personnel can open the second object transfer tempered glass door on the front side and put the products to be packaged in. After the packaging is completed, the staff uses work gloves to open the second object transfer tempered glass door on the left side from the inside of the working environment and completes the switching between packaged items and unpackaged items, which effectively improves work efficiency.
