Abstract
Description
Technical Field
[0001] This utility model relates to the field of preservation materials technology, and in particular to a preservation material testing device. Background Technology
[0002] Plastic wrap is a plastic product made of polymer materials. Because it can preserve food, it belongs to the category of preservation materials and is widely used in the food packaging field. Plastic wrap must undergo a series of tests before it can be put into the market. Testing is a very important process in the testing of plastic wrap, and its purpose is to test the mechanical properties of the plastic wrap.
[0003] However, most existing plastic wrap can only be tested for its tensile strength, not its compressive strength. When compressive strength testing is required, other testing equipment must be used, which can cause inconvenience and limitations for operators in actual use. Utility Model Content
[0004] The purpose of this invention is to provide a device for testing preservation materials to solve at least one of the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a food preservation material testing device, comprising a testing device body, wherein movable grooves are provided on both sides of the inner wall of the testing device body, and vertical scale lines are fixedly connected to the inner wall of the testing device body, and horizontal scale lines are provided on both sides of the testing device body, and support legs are fixedly connected to the bottom of the testing device body around its perimeter, a pressure testing mechanism is provided inside the testing device body, and a tensile testing mechanism is provided on both sides of the testing device body.
[0006] Preferably, the pressure detection mechanism includes a lead screw rotatably connected to the middle of the inner cavity of the main body of the detection device via a bearing. A handle is fixedly connected to the top of the lead screw, and a pressing plate is fitted onto the middle of the lead screw. A lead screw groove adapted to the lead screw is opened through the top of the pressing plate, and a moving block adapted to the moving groove is fixedly connected to the back of the pressing plate.
[0007] Preferably, the pressing plate is fitted into the middle of the lead screw via a lead screw groove and is slidably connected to the main body of the detection device via a moving block within the moving groove.
[0008] Preferably, the tensile testing mechanism includes an L-shaped connecting frame fixedly connected to both sides of the main body of the testing device. Each side of the L-shaped connecting frame is provided with an electric telescopic rod, and each output end of the two electric telescopic rods is provided with a positioning mechanism.
[0009] Preferably, a door is rotatably connected to the front of the main body of the detection device via a hinge, and a handle is fixedly connected to the front of the door.
[0010] Preferably, the positioning mechanism includes two U-shaped seats fixedly connected to one side of the output end of the two electric telescopic rods. Each of the two U-shaped seats has a threaded hole at its top, and a threaded rod is threadedly connected to the inner cavity of each threaded hole. A rotating block is fixedly connected to the top of each threaded rod, and a positioning block is fixedly connected to the bottom of each threaded rod.
[0011] Preferably, both the rotating block and the positioning block are made of rubber.
[0012] The beneficial effects of this utility model are as follows:
[0013] 1. In this utility model, by placing both ends of the preservation material, such as cling film, between the positioning block and the U-shaped seat, and then rotating the screw rod clockwise in the corresponding threaded hole via the rotating block, the positioning block moves down to press and fix the preservation material and cling film. After fixing, the output ends of the two electric telescopic rods drive the two U-shaped seats to move in opposite directions, thereby adjusting the distance between the two U-shaped seats. During adjustment, the preservation material and cling film move together to perform tensile testing. During testing, the tensile distance is checked through the horizontal scale lines on both sides. This not only makes it easier for operators to fix cling film materials of different thicknesses but also to perform tensile testing, thus effectively improving the convenience of operators using this device.
[0014] 2. In this utility model, by holding the handle and rotating it clockwise, the lead screw is driven to rotate. The lead screw drives the pressing plate through the lead screw groove to move down in the moving groove through the moving block to press and test the plastic wrap. During pressing, the distance of the pressing plate moving down is checked by looking at the vertical scale line. This makes it convenient for operators to test the pressure on plastic wrap of different thicknesses, thus enabling the device to have diversified testing effects. Attached Figure Description

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 protection scope of the present utility model.
[0021] This utility model provides, for example Figure 1-4 The invention relates to a food preservation material testing device, comprising a testing device body 1, with movable grooves 2 on both sides of the inner wall of the testing device body 1, vertical scale lines 3 fixedly connected to the inner wall of the testing device body 1, horizontal scale lines 5 on both sides of the testing device body 1, support legs 6 fixedly connected to the bottom of the testing device body 1, a pressure testing mechanism inside the testing device body 1, and a tensile testing mechanism on both sides of the testing device body 1.
[0022] Furthermore, the pressure detection mechanism includes a lead screw 7 rotatably connected to the middle of the inner cavity of the main body 1 of the detection device via a bearing. A handle 8 is fixedly connected to the top of the lead screw 7. A pressing plate 9 is fitted in the middle of the lead screw 7. A lead screw groove 10 adapted to the lead screw 7 is opened through the top of the pressing plate 9. A moving block 11 adapted to the moving groove 2 is fixedly connected to the back of the pressing plate 9. The pressing plate 9 is fitted in the middle of the lead screw 7 through the lead screw groove 10 and is slidably connected to the main body 1 of the detection device within the moving groove 2 via the moving block 11. With the pressure detection mechanism, it is convenient for operators to test the pressure of preservation materials such as preservation films of different thicknesses, thereby improving the convenience of operators.
[0023] Furthermore, the tensile testing mechanism includes an L-shaped connecting frame 12 fixedly connected to both sides of the main body 1 of the testing device. Each side of the L-shaped connecting frame 12 is equipped with an electric telescopic rod 13, and each side of the output end of the two electric telescopic rods 13 is equipped with a positioning mechanism. Through the tensile testing mechanism, it is convenient for operators to test the tensile strength of preservation materials and preservation films, thereby enabling the device to have diversified testing effects and improve the convenience for operators.
[0024] Furthermore, a door 4 is rotatably connected to the front of the main body 1 of the detection device via a hinge. A handle 19 is fixedly connected to the front of the door 4. By grasping the handle 19 and pulling it outward, the door 4 can be rotated along with the hinge to open the main body 1 of the detection device, thereby facilitating the operator to clean the inside of the main body 1 of the detection device.
[0025] Furthermore, the positioning mechanism includes two U-shaped seats 14 fixedly connected to one side of the output end of the two electric telescopic rods 13. Each of the two U-shaped seats 14 has a threaded hole 15 on its top, and a threaded rod 16 is threadedly connected to the inner cavity of each threaded hole 15. A rotating block 17 is fixedly connected to the top of each threaded rod 16, and a positioning block 18 is fixedly connected to the bottom of each threaded rod 16. Both the rotating block 17 and the positioning block 18 are made of rubber. Through the positioning mechanism, operators can easily perform protective positioning work on preservation materials and plastic wrap of different thicknesses, which not only facilitates the use of the operator but also prevents damage to the preservation materials and plastic wrap.
[0026] In practical implementation, the following steps are taken: First, grasp the handle 19 and pull it outward to open the door 4 via the hinge, opening the main body 1 of the detection device. Then, place both ends of the preservation material, such as cling film, between the positioning block 18 and the U-shaped seat 14. Next, the rotating block 17 drives the threaded rod 16 to rotate clockwise within the corresponding threaded hole 15, causing the positioning block 18 to move downward and press and fix the preservation material / cling film. After fixing, the output ends of the two electric telescopic rods 13 drive the two U-shaped seats 14 to move in opposite directions, adjusting the distance between them. During adjustment, the preservation material / cling film moves together for tensile testing. The tensile strength is checked via the horizontal scale lines 5 on both sides. The device allows for easy fixing of cling film materials of different thicknesses and enables tensile testing, thus significantly improving user convenience. Holding the handle 9 and rotating it clockwise rotates the lead screw 7. The lead screw 7, via the lead screw groove 10, drives the pressing plate 9 to move downwards through the moving block 11 into the moving groove 2 to press and test the cling film. The downward distance of the pressing plate 9 is checked via the vertical scale line 3, allowing operators to easily test the pressure applied to cling film materials of different thicknesses. This enables the device to perform diverse testing functions. Finally, the interior of the main body 1 of the testing device is cleaned.
