Description

Technical Field

[0001] The utility model relates to the technical field of anti-static polyester bags, in particular to a polyester bag weighing performance detection device. Background Art

[0002] Polyester cloth bags are commonly used items for industrial dust removal and daily storage. Polyester cloth bags are made of polyester fibers. This synthetic fiber has excellent physical properties. Polyester fibers have a high melting point and good thermal stability, which enables polyester cloth bags to maintain good performance in a certain high temperature environment. At the same time, polyester cloth bags have good acid and alkali resistance, which is particularly important in the field of industrial dust removal. The fiber structure and large surface area design of polyester cloth bags enable them to perform well in capturing and fixing tiny particles. This efficient filtering performance makes polyester cloth bags widely used in air purification and industrial dust removal. Polyester cloth bags are widely used in industrial dust removal due to their durability and functionality. It has a wide range of applications in the field of industrial dust removal. For example, polyester needle-punched felt filter materials can be used for a long time below 120°C and are suitable for dust removal and purification needs in various complex environments. With the improvement of environmental awareness and the tightening of industrial production standards, the demand for efficient and durable dust removal equipment and materials is increasing. Polyester bags, as a cost-effective solution, have been welcomed by the market. In the future, polyester bags may continue to innovate in material science and process technology to adapt to more diverse and complex usage scenarios. At the same time, the trend of environmental protection and sustainable development will also prompt the production of polyester bags to shift to more environmentally friendly materials and processes.

[0003] In the existing technology, the main disadvantages of the cloth bag weighing performance testing device are the low convenience of the testing process and the inability to highly simulate the usage scenario for testing, which correspondingly reduces the efficiency and effect of the testing, especially for the load-bearing performance testing of polyester cloth bags. Because the handle part and the containing part of the polyester cloth bag are usually integrally formed, the overall flexibility of the cloth bag is relatively high, resulting in the need to replace hooks of different diameters for weighing tests, which is time-consuming and labor-intensive. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a polyester bag weighing performance detection device.

[0005] Base comprises support, castor, and frame upper is provided with guide rail, and support and conveyer frames movable end contact site are provided with recoil spring or rubber cushion, and castor is arranged on the pin of base bottom four, to carry mobile handler location. The flexibility is low and it cannot highly simulate the use scenario for testing, which correspondingly reduces the efficiency and effect of the test, especially for the load-bearing performance test of polyester bags. Because the handle part and the containing part of the polyester bag are usually integrally formed, the overall flexibility of the bag is relatively high, resulting in the need to replace hooks of different diameters for weighing tests during weighing tests, which is time-consuming and labor-intensive. By installing the fixing device, when the user needs to weigh the polyester bag, the turntable is rotated according to the diameter of the polyester bag, and the sliding plate is extended or retracted along the slide to hook the polyester bag, and the weight is placed inside the polyester bag according to the weight to be tested. Then, the handle is rotated to raise or lower the polyester bag, thereby realizing simulation tests of polyester bags of different diameters at different heights.

[0006] Preferably, a shock absorbing device is fixed to the upper end surface of the support platform, and the shock absorbing device includes a buffer base, a buffer spring is fixed to the upper end surface of the buffer base, and the other end of the buffer spring is fixed to a support plate, and the upper end of the buffer base is fixed to a rotating base, and the outer wall of the rotating base is rotatably connected to a connecting plate, and the other end of the connecting plate is rotatably connected to the rotating base, and a hydraulic cylinder is fixed to the upper end surface of the buffer base, and the other end of the hydraulic cylinder is fixedly connected to the support plate, and a buffer plate is fixed to the upper end of the support plate. In the prior art, when testing a polyester bag, if the polyester bag breaks, the heavy object inside will fall off and hit the surface of the tool table to generate a huge noise, thereby affecting the operator and even damaging the surface of the work platform, causing injury to the user. The utility model installs a buffer base on the upper end of the support platform. When the user is testing and weighing and the internal weight falls off, it falls on the surface of the buffer plate. When the generated vibration is transmitted to the base, the buffer spring will deform, thereby converting the vibration energy into the elastic potential energy of the material. This energy conversion helps to reduce the amplitude and frequency of the vibration, thereby achieving the effect of alleviating the vibration. At the same time, the hydraulic cylinder inside the base is compressed and released, and the piston movement will generate resistance. This resistance can suppress the rebound oscillation after the spring absorbs the shock, thereby further reducing the vibration amplitude and increasing its ability to absorb vibration, thereby achieving shock absorption when the working weight falls off, reducing the generation of vibration, and avoiding damage to the support platform and the problem of eardrum damage to the staff.

[0007] Preferably, the surface of the handle is covered with a rubber sleeve, so that the staff can avoid slipping when using the handle.

[0008] Preferably, baffles are fixed to both side end surfaces of the rotating wheel, so as to prevent the rope from falling off the rotating wheel when moving.

[0009] Preferably, the buffer spring adopts a double-strand spring, which can better absorb and disperse impact energy through the double helix structure, thereby further reducing the vibration and noise of the mechanism and improving work efficiency and quality.

[0010] Preferably, the buffer plate is made of an elastic fiberboard. The elastic fiberboard has high elasticity and can quickly return to its original shape even after being squeezed or stretched, thereby further improving the shock absorption capacity of the buffer device.

[0011] Preferably, a latch is fixed to the upper end of the sliding plate to prevent the polyester bag from falling off the sliding plate when the fixing device is raised or lowered.

[0012] Beneficial effects

[0013] 1. In the prior art, the main disadvantages of the bag weighing performance testing device are that the testing process is not convenient and the use scenario cannot be highly simulated for testing, which correspondingly reduces the efficiency and effect of the test, especially for the load-bearing performance test of polyester bags. Because the handle part and the holding part of the polyester bag are usually integrally formed, the overall flexibility of the bag is relatively high, resulting in the need to replace hooks of different diameters for weighing tests, which is time-consuming and labor-intensive. By installing the fixing device, when the user needs to weigh the polyester bag, the turntable is rotated according to the diameter of the polyester bag, and the sliding plate is extended or retracted along the slide groove to hook the polyester bag, and the weight is placed inside the polyester bag according to the weight to be tested, and then the handle is rotated to raise or lower the polyester bag, thereby realizing simulation tests of polyester bags of different diameters at different heights.

[0014] 2. In the prior art, when testing a polyester bag, if the polyester bag breaks, the heavy object inside will fall off and hit the surface of the tool bench, causing a huge noise, thereby affecting the operator and even damaging the surface of the work platform, causing injury to the user. The utility model installs a buffer base on the upper end of the support platform. When the user is testing and weighing, the internal heavy object falls off and falls on the surface of the buffer plate. When the generated vibration is transmitted to the base, the buffer spring will deform, thereby converting the vibration energy into the elastic potential energy of the material. This energy conversion helps to reduce the amplitude and frequency of the vibration, thereby achieving the effect of alleviating vibration. At the same time, the hydraulic cylinder inside the base is compressed and released, and the piston movement will generate resistance. This resistance can suppress the rebound oscillation after the spring absorbs shock, thereby further reducing the vibration amplitude and increasing its ability to absorb vibration, thereby achieving shock absorption when the working heavy object falls off, reducing the generation of vibration, avoiding damaging the support platform and avoiding the problem of eardrum damage to the staff.
