Description
Technical Field
[0001] This utility model relates to the field of testing devices, and in particular to a testing device for the sealing performance of food packaging. Background Technology
[0002] In the food industry, packaging sealing performance is a key factor affecting the shelf life and quality and safety of food. If there are sealing defects in food packaging, outside air, moisture, microorganisms and other substances will enter the packaging, causing food to spoil and lose its flavor. At the same time, the gas inside the packaging may also leak, losing its protective function for the food. With the development of technology, various food packaging sealing performance testing devices have appeared on the market.
[0003] While commercially available food packaging sealing performance testing devices reduce space usage through their integrated structure, they lack protective features. During testing, liquids inside the device can easily drip onto the control panel, causing damage and affecting the device's lifespan. Furthermore, when removing food packaging, liquid residue on workers' hands not only affects operational comfort but also increases the risk of electric shock due to liquid dripping onto the control panel. These limitations are significant. Utility Model Content
[0004] The main purpose of this utility model is to provide a food packaging sealing performance testing device, which can effectively solve the problem that during the testing process, liquid inside the testing equipment can easily drip onto the control panel, causing damage to the equipment and affecting its service life. At the same time, when removing food packaging, liquid residue can easily remain on the hands of the staff, which not only affects the comfort of operation, but also increases the risk of electric shock as liquid can drip onto the control panel when operating the equipment.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A food packaging sealing performance testing device includes a testing machine. A testing barrel is fixedly installed on the top of the testing machine, and a control panel is provided on one side. A protective component is provided on the outer wall of the testing machine, and a transmission component is provided at one end. The protective component includes a rotating shaft and a protective plate. A driven gear is fixedly installed at one end of the rotating shaft. The transmission component includes a rack, which meshes with the driven gear. When the rack moves horizontally, it drives the driven gear, the rotating shaft, and the protective plate to rotate. A cooling component is provided at one end of the protective plate. The cooling component includes a motor and several cooling fan blades. When the motor operates, it can drive the several cooling fan blades to rotate in the same direction.
[0006] Preferably, the protective plate has a mounting groove at the bottom and a slot at the top, with the slot penetrating the mounting groove.
[0007] Preferably, the protective assembly further includes a fixed block, a sliding block, a screw, and a fastening nut. The rotating shaft and the screw are respectively fixedly installed on both sides of the testing machine. The rotating shaft is rotatably connected to the fixed block and the testing machine. The protective plate is slidably sleeved on the rotating shaft. The sliding block is slidably sleeved on the rotating shaft and the screw. The fastening nut is threaded onto the screw, and one end of the fastening nut abuts against one end of the sliding block.
[0008] Preferably, the transmission assembly further includes an electric push rod and a mounting base. The mounting base is fixedly installed on the outer wall of the testing machine, the electric push rod is fixedly installed on the top of the mounting base, the rack is fixedly connected to the output end of the electric push rod, a protective cover is fixedly installed on the outer wall of the testing machine, and the transmission assembly is disposed inside the protective cover.
[0009] Preferably, the top of the mounting base is provided with a sliding groove, and the rack slides in cooperation with the inner wall of the sliding groove.
[0010] Preferably, the cooling assembly further includes a mounting frame and several rotating shafts. The mounting frame is fixedly mounted on the top of the protective plate, the motor is fixedly mounted on the inner wall of the mounting frame, the several rotating shafts are rotatably connected to the mounting frame, and the several cooling fan blades are respectively fixedly sleeved on the rotating shafts.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. By shielding the testing barrel with the protective plate of the protective component, it can effectively prevent the fragments from splashing due to packaging breakage during the testing process. It can also reduce the probability of liquid inside the testing barrel splashing onto the control panel, reducing the risk of electric shock to the staff. At the same time, the protective cover protects the transmission components, avoiding safety hazards caused by exposed parts. In addition, different rotation angles of the protective plate can have different effects, providing protection and dust prevention for the control panel when the testing machine is running and when it is not running, making it highly versatile.
[0013] 2. By driving multiple cooling fan blades to rotate synchronously with a motor, combined with the slots in the protective plate to enhance airflow, the temperature of the equipment and the testing environment can be quickly reduced, preventing temperature from affecting the testing accuracy and equipment lifespan. At the same time, by increasing the wind speed, residual liquid on the workers' hands can be quickly dried, making it easier for workers to continue operating and further reducing the probability of electric shock, thus further improving applicability.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0017] like Figure 1-4As shown, a food packaging sealing performance testing device includes a testing machine 1. A testing barrel 102 is fixedly installed on the top of the testing machine 1, and a control panel 101 is provided on one side. A protective component 2 is provided on the outer wall of the testing machine 1, and a transmission component 5 is provided at one end. The protective component 2 includes a rotating shaft 202 and a protective plate 203. A driven gear 207 is fixedly installed at one end of the rotating shaft 202. The transmission component 5 includes a rack 503, which meshes with the driven gear 207. When the rack 503 moves horizontally, it drives the driven gear 207, the rotating shaft 202, and the protective plate 203 to rotate. The bottom of the protective plate 203 has an installation groove 2031, and the top has a slot 2032, which passes through the installation groove 2031. The protective component 2 also includes a fixing block 201, a sliding block 204, a screw 205, and a fastening nut 206. Shaft 202 and screw 205 are fixedly installed on both sides of the testing machine 1. Shaft 202 is rotatably connected to fixed block 201 and testing machine 1. Protective plate 203 is slidably sleeved on shaft 202. Sliding block 204 is slidably sleeved on shaft 202 and screw 205. Fastening nut 206 is threaded on screw 205, and one end abuts against one end of sliding block 204. Transmission assembly 5 also includes electric push rod 501 and mounting base 500. Mounting base 500 is fixedly installed on the outer wall of testing machine 1. Electric push rod 501 is fixedly installed on the top of mounting base 500. Rack 503 is fixedly connected to the output end of electric push rod 501. Protective cover 3 is fixedly installed on the outer wall of testing machine 1. Transmission assembly 5 is located inside protective cover 3. Slide groove 504 is opened on the top of mounting base 500. Rack 503 slides in cooperation with the inner wall of slide groove 504.
[0018] After the testing is completed, the vacuum pump is turned off via control panel 101, and the electric push rod 501 is manually turned off. The output end of the electric push rod 501 retracts and drives the rack 503 to move horizontally. When the rack 503 moves, it meshes with the driven gear 207, driving the driven gear 207 and the rotating shaft 202 to rotate. When the rotating shaft 202 rotates, it drives the protective plate 203 to rotate until one side of the protective plate 203 is in contact with the testing machine 1. At this time, the output end of the electric push rod 501 is completely retracted, thus protecting the control panel 101. At the same time, when the protective plate 203 unfolds, it can reduce the probability of liquid in the testing tank 102 spilling onto the control panel during the testing process. It has a strong protective effect, not only providing dust prevention but also protecting the control panel 101 during the testing process, making it highly applicable. The testing machine 1 is existing technology, specifically the MFY-3 model of the food sealing testing machine in the prior art.
[0019] like Figure 5As shown, in one embodiment, a cooling component 4 is provided at one end of the protective plate 203. The cooling component 4 includes a motor 402 and a plurality of cooling fan blades 405. When the motor 402 operates, it can drive the plurality of cooling fan blades 405 to rotate in the same direction. The cooling component 4 also includes a mounting frame 401 and a plurality of rotating shafts 404. The mounting frame 401 is fixedly mounted on the top of the protective plate 203. The motor 402 is fixedly mounted on the inner wall of the mounting frame 401. The plurality of rotating shafts 404 are rotatably connected to the mounting frame 401. The plurality of cooling fan blades 405 are respectively fixedly sleeved on the rotating shafts 404. The cooling component 4 also includes a plurality of worm gears 406 and worms 403. One end of the worm 403 is rotatably connected to the inner wall of the mounting frame 401, and the other end is fixedly connected to the output end of the motor 402. The plurality of worm gears 406 are respectively fixedly sleeved on the plurality of rotating shafts 404 and are all engaged with the worm 403.
[0020] After the output end of the motor 402 operates, it drives the worm 403 to rotate. When the worm 403 rotates, it meshes with several worm wheels 406 and drives the worm wheels 406 to rotate. When the worm wheels 406 rotate, they drive the rotating shaft 404 and the cooling fan blades 405 to rotate. After the several cooling fan blades 405 rotate, they can blow air onto a part of the control panel 101, increase the wind speed, and thus reduce the temperature of the area of the control panel 101, making it easier for the staff to operate. At the same time, they can dry the liquid on the staff's hands during the testing process, and also dissipate heat from the testing machine 1, further improving its applicability. The worm gear 403 is a four-headed worm gear, and the worm wheel 406 has 20 teeth. The transmission ratio between the worm gear 403 and the worm wheel 406 is 5. The motor 402 is a miniature DC motor with a rated speed of 1400 r / min. When its output drives the four-headed worm gear 403 to rotate, due to the transmission ratio between the worm gear and the 20-tooth worm wheel 406, the actual rotational speed of the worm wheel 406, the connected rotating shaft 404, and the cooling fan blades 405 is 280 r / min. This speed allows the fan blades to generate a stable airflow, avoiding insufficient heat dissipation due to excessively low speed, and preventing noise and energy waste due to excessively high speed. At the same time, the high transmission efficiency of the four-headed worm gear can reduce the motor load and extend the service life of the components.
[0021] Working principle: During food testing, staff connect the testing barrel 102 to the vacuum pump inside the testing machine 1 via a connecting cable. After placing the food packaging inside the testing barrel 102, the lid is tightened. Then, the pressure of the vacuum pump is adjusted via the control panel 101 to draw pressure from inside the testing barrel 102. The food packaging is tested for leaks within the testing barrel 102. Staff first power on the electric push rod 501 and the motor 402. Simultaneously, the motor 402 is started during the testing process. The output of the motor 402 drives the worm gear 403 to rotate. When the worm gear 403 rotates, it meshes with several worm wheels 406, driving the worm wheels 406 to rotate. When the worm wheels 406 rotate, they drive the rotating shaft 404 and the cooling fan blades 405 to rotate. The rotation of the cooling fan blades 405 blows air onto a point on the control panel 101, increasing the airflow speed and thus lowering the temperature of the area on the control panel 101. This facilitates operation for staff and also dries liquids on their hands during the testing process, making it highly versatile. After the testing is completed, the vacuum pump is turned off via the control panel 101, and the electric push rod 501 is manually turned off. The output end of the electric push rod 501 retracts and drives the rack 503 to move horizontally. When the rack 503 moves, it meshes with the driven gear 207 and drives the driven gear 207 and the rotating shaft 202 to rotate. When the rotating shaft 202 rotates, it drives the protective plate 203 to rotate until one side of the protective plate 203 is in contact with the testing machine 1. At this time, the output end of the electric push rod 501 is completely retracted, thus protecting the control panel 101. At the same time, when the protective plate 203 is unfolded, it can reduce the probability of liquid in the testing tank 102 spilling onto the control panel during the testing process.
