Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of fur testing equipment, specifically relating to a device for testing the density of sheep wool shearings. Background Technology
[0002] Shearling products have recently become very popular in the market. Different customers have different requirements for wool density, but in reality, there is a lack of relatively accurate and objective testing devices and methods to meet this demand. Currently, testing mainly relies on the experience of practitioners and subjective judgment by visual inspection, which is prone to large judgment errors and cannot perform specific statistical analysis of wool density in different areas of the same piece of shearling. This approach is highly subjective, lacks objectivity, and cannot meet the accuracy requirements. Therefore, a sheepskin wool density testing device is needed to solve the above technical problems. Utility Model Content
[0003] To address the aforementioned deficiencies in existing technologies, this utility model provides a sheepskin wool density testing device, comprising a measuring gauge mounted on a measuring frame. The measuring frame includes a support plate with multiple evenly distributed legs at its bottom. The measuring gauge is located on the upper surface of the support plate, and a pressure plate is located on the lower surface of the support plate. A connecting column is connected to the pressure plate, penetrating the support plate and connecting to the measuring gauge. The measuring gauge can be a dial indicator or a percentage indicator. The dial indicator or percentage indicator can be a lever-type or gear-type indicator.
[0004] Preferably, a vertical frame is fixed to the upper surface of the support plate. The measuring instrument includes a housing, and a dial and pointer that cooperate with each other are provided inside the housing. The dial has a scale, and a rotating shaft is provided at the center of the dial. The pointer is fixedly connected to one end of the rotating shaft. A connecting plate is provided behind the dial, and the connecting plate is fixedly connected to the housing. The other end of the rotating shaft passes through the connecting plate and is fixedly connected to a gear. The rotating shaft is rotatably connected to the connecting plate through a bearing. The gear meshes with a vertical rack. A vertical guide plate is fixed to the connecting plate. The guide plate has a guide groove, and a vertical guide strip is slidably arranged in the guide groove. The guide strip is fixedly connected to the rack. The upper end of the connecting column is connected to the lower end of the rack.
[0005] Preferably, the top of the housing is provided with a handle. This facilitates the handling of the device and allows for the inspection of fur in different areas, thereby improving inspection efficiency.
[0006] Preferably, the support legs are provided in three parts, and the pressure plate is located between the three support legs. The support legs are arranged in a tripod configuration, which not only improves the stability of the measuring frame placed on the fur, but also prevents the support legs from having a large contact area with the fur and damaging it. It also prevents the support legs from contacting the leather surface below the fur and penetrating the leather surface, thus avoiding damage to the leather surface.
[0007] This invention also includes other components that enable the normal use of a sheepskin wool density testing device, all of which are conventional techniques in the field. Furthermore, devices or components not specified in this invention, such as gears, racks, and dial indicators, all employ conventional techniques and equipment in the field.
[0008] Working Principle: First, the sheepskin sample to be tested is laid flat on a hard, level surface. Then, the testing device is placed vertically on the sheepskin surface, with the support legs in contact with the sheepskin. The sheepskin pushes up the lower pressure plate, and the reaction force of the wool on the lower pressure plate drives the pointer on the instrument panel to rotate, providing an objective value as a measure of wool density. Theoretically, the higher the wool density per unit area, the greater the supporting force on the lower pressure plate, and the higher the value indicated by the pointer. This allows for a relatively objective assessment of the wool density of the same type of sheepskin product. Furthermore, by measuring different areas on the same piece of sheepskin, the uniformity of wool density in the sheepskin product can be evaluated, thus determining the quality of the sheepskin product.
[0009] The beneficial effects of this utility model are: it can objectively detect the wool density of sheepskin products, the operation is simple, it does not damage the leather, the detection efficiency is high, and the detection accuracy is improved. Attached Figure Description

[0014] The present invention will now be clearly described with reference to the accompanying drawings and specific embodiments. This description is merely for explaining the present invention and is not intended to limit it. Any modifications, equivalent substitutions, improvements, etc., made by those skilled in the art based on the embodiments of the present invention without inventive effort to obtain all other embodiments should be included within the protection scope of the present invention.
[0015] Example 1
[0016] like Figure 1 As shown, this utility model provides a wool density testing device for sheepskin, including a measuring gauge mounted on a measuring frame. The measuring frame includes a support plate 1, with multiple legs 6 evenly distributed at the bottom of the support plate 1. The measuring gauge is located on the upper surface of the support plate 1, and a pressure plate 8 is provided on the lower surface of the support plate 1. The pressure plate 8 is connected to a connecting post 7, which passes through the support plate 1 and connects to the measuring gauge. The measuring gauge is a dial indicator or a micrometer.
[0017] The top of the housing 3 is provided with a handle 14. This facilitates the handling of the device and allows for the inspection of fur in different areas, thereby improving inspection efficiency.
[0018] The support legs 6 are provided in three parts, and the pressure plate 8 is located between the three support legs 6. The support legs 6 are arranged in a tripod configuration, which not only improves the stability of the measuring frame placed on the fur, but also prevents the support legs 6 from having a large contact area with the fur and damaging it, and also prevents the support legs 6 from contacting the leather surface below the fur and penetrating the leather surface, thus avoiding damage to the leather surface.
[0019] During operation, the sheepskin sample to be tested is first laid flat on a hard, level surface. The testing device is then placed vertically on the sheepskin surface, with the support legs in contact with the sheepskin. The sheepskin pushes up the lower pressure plate, and the reaction force of the wool on the lower pressure plate rotates the pointer on the instrument panel, providing an objective value as a measure of wool density. Theoretically, the higher the wool density per unit area, the greater the supporting force on the lower pressure plate, and the higher the pointer value. This allows for a relatively objective assessment of the wool density of the same type of sheepskin product. Furthermore, by measuring different areas on the same piece of sheepskin, the uniformity of wool density in the product can be evaluated, thus assessing the quality of the sheepskin product. After each measurement, the measuring device is lifted, and the lower pressure plate falls back to its initial position under gravity (when the lower pressure plate is flush with the lower end of the support legs), and the pointer resets.
[0020] Example 2
[0021] like Figure 1-2As shown, the difference between this embodiment and Embodiment 1 is that a vertical frame 2 is fixed on the upper surface of the support plate 1, the measuring instrument includes a housing 3, and a dial and pointer 5 that cooperate with each other are provided inside the housing 3. The dial has a scale, and a rotating shaft 4 is provided at the center of the dial. The pointer 5 is fixedly connected to one end of the rotating shaft 4. A connecting plate 12 is provided behind the dial. The connecting plate 12 is fixedly connected to the housing 3. The other end of the rotating shaft 4 passes through the connecting plate 12 and is fixedly connected to a gear 13. The rotating shaft 4 is rotatably connected to the connecting plate 12 through a bearing. The gear 13 meshes with a vertical rack 9. A vertical guide plate 11 is fixed on the connecting plate 12. The guide plate 11 has a guide groove. A vertical guide strip 10 is slidably arranged in the guide groove. The guide strip 10 is fixedly connected to the rack 9. The upper end of the connecting column 7 is connected to the lower end of the rack 9.
[0022] During operation, the sheepskin sample to be tested is first laid flat on a hard, level surface. The testing device is then placed vertically on the sheepskin surface, with the support legs in contact with the sheepskin. The sheepskin pushes up the lower pressure plate, causing the rack to move upwards. The upward movement of the rack drives the gears to rotate, which in turn rotates the pointer. The higher the value indicated by the pointer, the greater the wool density. The device primarily uses the reaction force of the wool on the lower pressure plate to rotate the pointer on the instrument panel, providing an objective value as a measure of wool density. Theoretically, the greater the wool density per unit area, the greater the supporting force on the lower pressure plate, and the higher the pointer value. This allows for a relatively objective assessment of the wool density of the same type of sheepskin product. Furthermore, by measuring different areas on the same piece of sheepskin, the uniformity of wool density in the product can be evaluated, thus assessing the quality of the sheepskin product. After each measurement, the measuring device is lifted, and the lower pressure plate falls back to its initial position under gravity (when the lower pressure plate is flush with the lower end of the support legs), and the pointer resets.
[0023] The dial indicator and percentage indicator in the above embodiments are all existing technologies. This application does not make any improvements to them, but only utilizes their existing functions. For their specific structure and principle, please refer to the product manual or existing technical information, which are all existing technologies.
[0024] The embodiments of this utility model have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
