Description

TECHNICAL FIELD

[0001] The utility model relates to resource recycling technical field especially recycling resource's weighing device technical field, concretely relates to a kind of electronic recycling scale and recycling box for waste recycling. BACKGROUND

[0002] In today's society, with the acceleration of urbanization and the improvement of people's living standards, the amount of household waste is increasing. The recycling and disposal of household waste has become an environmental problem that needs to be solved urgently. According to statistical data, the global household waste generated each year has reached 2 billion tons, and China, as one of the world's largest waste producers, has generated more than 300 million tons of municipal household waste each year. This huge data not only puts a huge pressure on the environment, but also causes a waste of resources.

[0003] Among the household waste, a considerable part is waste with recycling value, such as paper, plastic, glass and metal, etc. If these recyclable materials can be effectively classified and recycled, not only can the pressure of landfill and incineration be reduced, but also the possibility of resource reuse can be provided. However, there are still many problems in the waste recycling system in China at present.

[0004] Firstly, the existing waste recycling mechanism is not perfect. Although many cities have established garbage classification system, in actual operation, many residents still lack the awareness of classification of recyclable materials, which leads to the mixing of recyclable materials and non-recyclable materials, affecting the recycling efficiency of waste. In addition, the recycling facilities and services in some places are not in place, and residents lack convenience when putting recyclable materials, which affects the enthusiasm of the public. Secondly, the marketization degree of waste recycling industry is not high. Although many enterprises and individuals participate in waste recycling, the overall industry development is still in a non-standard state, leading to unstable recycling prices, and many small recycling stations exist in the situation of low-price purchase, affecting the enthusiasm of residents. At the same time, the lack of effective supervision mechanism makes some unscrupulous traders violate the rules in the recycling process, pollute the environment, and even illegally handle recyclable resources. Thirdly, the lack of technology is also an important factor restricting waste recycling. At present, the classification, sorting and reprocessing technology of waste still needs to be improved. The recycling facilities in many areas are in poor condition, leading to low efficiency of recycling materials and inability to maximize the use of resources. With the development of technology, intelligent and automated recycling systems have gradually entered the market, but the popularization rate is still not high. In summary, the recycling status of household waste faces many challenges, and comprehensive management is needed from policy, technology, market and public awareness. Only through perfect recycling system, scientific management mechanism and extensive social participation, can the waste recycling rate be effectively improved, the efficient use of resources be realized, and the contribution to sustainable development be made.

[0005] In order to improve the enthusiasm of garbage discarders to actively carry out garbage recycling, the prior art has provided a garbage recycling cabinet such as paid recycling, which can be specifically seen from the garbage recycling cabinet and garbage recycling system disclosed in the publication No. CN208647731 U. The technology provides a paid recycling mechanism. As long as the recycling system accepts the garbage of the depositor, the system will automatically update the virtual resources in the account according to the corresponding account information, which will greatly improve the enthusiasm of the depositor to carry out garbage recycling and gradually cultivate people's classification and recycling of waste with recycling value. However, the existing technology only provides such a set of system technology without detailed refinement, for example, how to price or measure different recyclable items, which needs to be further clarified. Practical new type content

[0006] In order to solve the weighing problem in the process of pricing waste according to weight in the paid recycling of waste, the present application provides an electronic recycling scale for waste recycling and a recycling bin for solving the weighing problem of recyclable waste. The present application provides an electronic recycling scale specially used for waste recycling, which can automatically weigh the waste put into the recycling bin by the depositor, so that the value of the recycled waste based on the weighing is determined and the paid feedback to the depositor is realized. Of course, it is particularly emphasized that the present application mainly provides an electronic recycling scale suitable for weighing and recycling waste, which solves the weighing problem of recycled waste, and is aimed at the subsequent paid feedback to the depositor and the payment part, which is not the content required to be protected by the present application, and the existing technology can be used.

The installation position of the foot can be located at the edge of the scale plate and stably supported, which has no uniqueness and is very convenient to install. At the same time, due to the discrete way of the foot, it can meet the scale plates of different shapes and sizes, which embodies the technical advantage of wide range of use. Finally, since multiple feet are used for support, multi-point support is realized, which has good stability.

[0032] Embodiment 1:

[0033] The present embodiment provides an electronic recycling scale for waste recycling as shown in the description Figures 3-6 The electronic recycling scale for waste recycling as shown in the description comprises a mounting assembly, the mounting assembly comprises three circumferentially arranged or four rectangularly arranged supporting legs 5 for supporting the weighing plate 2, the supporting leg 5 is provided with an L-shaped step 12 for placing the weighing plate 2, the bottom surface of the L-shaped step 12 has a groove for mounting a pressure sensor 4, the pressure sensor 4 is in abutting contact with the weighing plate 2; the supporting leg 5 is further fixedly provided with a shaft sleeve 6 for mounting a screw rod, the supporting leg 5 is fixedly mounted by the screw rod installed in the shaft sleeve 6 to form a mounting assembly for supporting the weighing plate 2, and an interface 10 for outputting the electric signal of the pressure sensor 4 is detachably fixedly mounted on the weighing plate 2 or the supporting leg 5.

[0034] The electronic recycling scale provided by the present embodiment has the same function as the existing electronic scale, and is suitable for object weight measuring devices, but differs from the existing electronic scale in that the electronic recycling scale provided by the present embodiment is mainly suitable for electronic weighing in the recycling box, and the improvement point is in the mounting structure and the structure of the electronic scale itself. The working principle of the present embodiment is as follows:

[0035] The waste / recyclable material is disposed of according to regulations, such as directly from the disposal port of the recycling bin or after verification. This part is not part of this embodiment and will not be described in detail. When the disposed waste falls onto the weighing plate 2 of the electronic scale, the pressure sensor 4 converts the pressure into an electrical signal, which is output through interface 10 for post-processing, including display and calculation. The processing method based on the electrical signal output by interface 10 is determined by the application scenario and depends on the application scenario of this embodiment. For example, if it is for display, a display device can be connected through interface 10; if it is for post-calculation, other processing modules can be connected through interface 10 for calculation and display. This part is very mature prior art and is not the content protected by this embodiment, so it will not be described in detail here.

[0036] Example 2:

[0037] This embodiment is a further structural improvement based on Embodiment 1. See the appendix of the specification for details. Figures 3-6 As shown, to facilitate the installation of the weighing plate 2 and improve the compatibility of the support legs 5 with different sizes of weighing plates 2, in this embodiment, the support legs 5 are provided with fasteners 11 on the side wall of the L-shaped step 12 for connecting the support legs 5 and the weighing plate 2. Using the L-shaped step 12 and symmetrical support legs 2 for support can meet the needs of weighing plates 2 of different sizes, and with the fasteners 11 for fixation, it achieves multiple technical effects such as convenient installation, wide application range, and high stability. First, from the perspective of convenient installation, since the support legs 5 are discrete individuals, they can be supported by symmetrical support legs 2 in different combinations, such as three support legs 5 in an isosceles triangle or four support legs 5 in a rectangular layout. The installation position of the support legs 5 only needs to be located at the edge of the weighing plate 2 and provide stable support; it is not unique, making installation very convenient. At the same time, precisely because the support legs 5 are discrete, they can meet the needs of weighing plates 2 of different shapes and sizes, demonstrating the technical advantage of wide application range. Finally, the use of multiple support legs 5 provides multi-point support, resulting in good stability.

[0038] In order to reduce the impact generated when the waste is put in, in the embodiment, the upper surface of the scale plate 2 is provided with a plurality of discrete shock-absorbing rubbers 3, the shock-absorbing rubbers 3 are columnar rubber materials and are embedded in the scale plate 2, and the end surface of the shock-absorbing rubber 3 is 1mm-2mm higher than the upper surface of the scale plate 2. The scale plate 2 is mainly used for placing the storage box 1 and weighing the weight of the object put in, and when repeatedly putting in the waste, a downward impact force is generated on the storage box 1, and the shock-absorbing rubbers 3 can effectively avoid the problem of structural deformation caused by the mutual impact between the storage box 1 and the scale plate 2, and at the same time, the shock-absorbing rubbers 3 are distributed in a discrete array point shape, which can effectively avoid the problem of poor contact stability caused by structural deformation, thereby causing the problem of uneven stress on the scale plate 2. The shock-absorbing rubbers 3 are 1mm-2mm higher than the surface of the scale plate 2, of course, this distance is only preferred, and can be increased to 3mm or 4mm on this basis; therefore, even if there is a small gap or unevenness between the storage box 1 and the scale plate 2, better fitting can be achieved.

[0039] In order to avoid the overall center of gravity of the storage box 1 from being offset due to the uneven stacking of the waste or the large density difference of the waste in repeated waste putting, thereby affecting the weighing of the electronic recycling scale, preferably, the scale plate 2 is provided with a storage box 1 for accommodating waste, and any one of the supporting legs 5 is detachably and fixedly connected with a side plate 7 for limiting the transverse movement of the storage box 1. The side plate 7 can effectively constrain the storage box 1, avoid the problem of center of gravity offset and inclination of the storage box 1.

[0040] In order to further improve the weighing accuracy and reduce the longitudinal friction between the storage box 1 and the side plate 7, thereby affecting the weighing, preferably, a plurality of strip-shaped grooves for accommodating steel balls 8 are arranged on the side of the side plate 7 close to the storage box 1, and a limiting structure 9 for limiting the movement of the steel balls 8 is further arranged in the strip-shaped groove. When the storage box 1 contacts the side plate 7, the surface of the storage box 1 will first contact the steel balls 8 due to the action of the steel balls 8, and the steel balls 8 are free to roll, so the friction is very small. Therefore, the actual weight of the storage box 1 can be accurately measured by the scale plate 2 below, effectively reducing the problem of large measurement error caused by possible friction between the storage box 1 and the side plate 7. As an optional way of the limiting structure 9, in the embodiment, the limiting structure 9 adopts any one of a metal retainer, a matched retainer plate or a retainer mold.
