AI Technical Summary
[0003]目前，在利用皮革振荡拉软机对皮革进行打软处理的过程中，往往皮革都是未经过裁切等处理工序的，为原始皮革，这就导致对于皮革的面积、厚度等参数都是不固定的，而为了得到皮革的打软率，往往需要根据皮革打软前与打软后的面积、厚度等参数的前后数据对比并计算而得来的，因此，这就需要在皮革进行打软前与打软后均对皮革的面积、厚度等参数进行测量，而传统的测量方式都是通过人工进行测量的方式，非常的麻烦，而且人工测量需要借助到测量尺等工具对皮革轮廓等依次测量，测量效果比较低，工作效率不高
[0013]本实用新型的优点在于：本实用新型中的上料机构，通过增设的摄像组件以及测厚组件的配合，来在皮革上料对通过的皮革的面积以及厚度进行检测，无需再由人工检测，非常的方便，工作效率也提升了；另外，在利用摄像仪对皮革的轮廓进行检测时，还能同时实现对通过皮革的张数的检测。

Abstract
Description
Technical Field
[0001] This utility model relates to the field of leather processing, and in particular to a feeding mechanism for a leather oscillating and softening machine. Background Technology
[0002] The leather oscillating softening machine is a through-type machine for softening loose leather fibers. It is suitable for softening thicker leathers such as shoe uppers, bag leathers, and sofa leathers that are dried under vacuum or in a stretched state. It can also be used for the oscillating softening process of fur and leather products.
[0003] Currently, in the process of softening leather using a leather oscillating softening machine, the leather is often raw and unprocessed, without any cutting or other treatments. This results in inconsistent parameters such as the area and thickness of the leather. To obtain the softening rate, it is often necessary to compare and calculate the area and thickness before and after softening. Therefore, it is necessary to measure the area and thickness of the leather both before and after softening. However, traditional measurement methods rely on manual measurement, which is very cumbersome. Manual measurement requires the use of measuring rulers and other tools to measure the outline of the leather sequentially, resulting in low measurement accuracy and low work efficiency. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a feeding mechanism for a leather vibrating softening machine that can detect the area and thickness of leather before softening.
[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a feeding mechanism for a leather vibration stretching machine, including a feeding frame and a feeding conveyor belt disposed on the feeding frame, the innovation of which is: The feeding frame is also equipped with a camera assembly and a thickness measuring assembly located above the feeding conveyor belt. The camera assembly includes a camera for scanning the outline of the leather. The thickness measuring assembly includes at least one thickness measuring wheel located above the feeding conveyor belt. A gap is left between the thickness measuring wheel and the feeding conveyor belt to allow the leather to pass through. The thickness measuring wheel moves up and down vertically under the influence of leather of different thicknesses.
[0006] Furthermore, the thickness measuring wheel is mounted on the feeding frame with the cooperation of the mounting base. The mounting base includes a fixed plate, a lifting slide rail, a lifting slider, and a rotating shaft. The fixed plate is fixed to the feeding frame. A lifting slider is installed on one side of the fixed plate. The thickness measuring wheel is fitted on the outside of the rotating shaft, and a bearing is provided between the thickness measuring wheel and the rotating shaft. A vertical lifting slide rail is provided on one side of the rotating shaft, and the lifting slide rail cooperates with the lifting slider to realize the free up and down movement of the thickness measuring wheel.
[0007] Furthermore, the feeding frame is also provided with a horizontally arranged profile, and the extension direction of the profile is perpendicular to the conveying direction of the leather. The fixing plate is fixed to the profile by bolts. The profile is also provided with a sliding groove for the bolts to slide horizontally, and the sliding groove extends along the long axis of the profile.
[0008] Furthermore, there are several thickness measuring wheels, which are arranged side by side on the loading frame in a horizontal direction perpendicular to the conveying direction of the leather.
[0009] Furthermore, a first protective frame is provided on the outside of the camera to cover the camera, and a camera opening is provided at the bottom of the first protective frame to avoid the camera of the camera.
[0010] Furthermore, a second protective frame is provided on the outer side of the thickness measuring wheel to cover the thickness measuring wheel. The second protective frame has a cavity for accommodating the thickness measuring wheel for installation and vertical movement. The lower part of the thickness measuring wheel extends out of the second protective frame, and an opening is provided at the bottom of the second protective frame to accommodate the lower part of the thickness measuring wheel extending out.
[0011] Furthermore, the feeding frame is also equipped with a hygrometer for detecting the humidity of the leather.
[0012] Furthermore, the feeding frame is also equipped with a hardness tester for detecting the hardness of leather.
[0013] The advantages of this utility model are as follows: The feeding mechanism of this utility model, through the cooperation of the added camera component and thickness measuring component, can detect the area and thickness of the leather passing through during leather feeding, eliminating the need for manual inspection, which is very convenient and improves work efficiency; in addition, when using the camera to detect the outline of the leather, the number of leather sheets passing through can also be detected at the same time.
[0014] The installation of the thickness measuring roller is achieved through the cooperation of components such as lifting slide rail, lifting slider, rotating shaft, and bearing. The lifting slide rail and lifting slider guide and limit the up and down movement of the thickness measuring roller to prevent it from deviating during up and down movement. The rotating shaft and bearing are used to allow the thickness measuring roller to rotate freely so that it can rotate freely on the surface of the leather and avoid affecting the transport of the leather.
[0015] The profile is designed to work with the fixed plate, providing a base for the horizontal movement of the fixed plate, thereby facilitating the adjustment of the position of the thickness measuring roller.
[0016] By setting a first protective frame on the outside of the camera and a second protective frame on the outside of the thickness measuring wheel, the camera and the thickness measuring wheel are protected to prevent external solid particles from damaging the camera or the thickness measuring wheel or interfering with their normal operation, thus ensuring the smooth conduct of leather inspection.

[0021] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.
[0022] like Figures 1-3 The illustrated feeding mechanism for a leather vibrating stretching machine includes a feeding frame 1 and a feeding conveyor belt 2 mounted on the feeding frame 1. The feeding conveyor belt 2 is driven to rotate by a feeding motor mounted on the feeding frame 1. A feeding auxiliary platform 21 is also provided on the feeding frame 1 at the feeding side of the feeding conveyor belt 2 to facilitate personnel feeding leather. A translation roller 11 is also installed at the bottom of the feeding frame 1, and a translation guide rail is also provided on the ground to cooperate with the translation roller 11. Through the cooperation of the translation roller 11 and the translation guide rail, the feeding frame 1 can move horizontally as a whole, thereby moving closer to or away from the vibrating stretching machine.
[0023] The feeding frame 1 is also equipped with a camera assembly and a thickness measuring assembly located above the feeding conveyor belt 2.
[0024] The camera assembly includes a camera for scanning the contours of leather. A gantry frame 4 for mounting the camera is also installed on the loading frame 1. The gantry frame 4 is fixed to the loading frame 1 on both sides by bolts and nuts. A first protective frame 41 is provided outside the camera to enclose it. An opening for the camera lens is provided at the bottom of the first protective frame 41 to avoid obstructing the viewfinder. The first protective frame 41 protects the camera from damage caused by external solid particles or interference with its normal operation, ensuring that the camera can successfully scan and inspect the outer contours of the leather.
[0025] The thickness measuring component includes several thickness measuring wheels 3 arranged in parallel on the loading frame in a horizontal direction perpendicular to the conveying direction of the leather. There is a gap between the thickness measuring wheels 3 and the loading conveyor belt 2 to allow the leather to pass through. The thickness measuring wheels 3 move up and down in the vertical direction under the drive of leather of different thicknesses.
[0026] The thickness measuring wheel 3 is mounted on the feeding frame 1 with the cooperation of the mounting base. The mounting base includes a fixed plate 31, a lifting slide rail 33, a lifting slider 32, and a rotating shaft 34. The fixed plate 31 is an L-shaped plate. One side of the fixed plate 31 is fixed to the feeding frame 1. A lifting slider 32 is installed on the other side of the fixed plate 31. The thickness measuring wheel 3 is fitted on the outside of the rotating shaft 34. A bearing 35 is provided between the thickness measuring wheel 3 and the rotating shaft 34. A through hole is opened in the middle of the thickness measuring wheel 3 to accommodate the installation of the rotating shaft 34 and the bearing 35. The inner ring of the bearing 35 is fitted on the outer wall of the rotating shaft 34. The outer ring of the bearing 35 is in contact with the inner wall of the thickness measuring wheel 3. A vertical lifting slide rail 33 is provided on one side of the rotating shaft 34. The lifting slide rail 33 cooperates with the lifting slider 32 to realize the free up and down movement of the thickness measuring wheel 3. The installation of the thickness measuring roller 3 is achieved through the cooperation of components such as the lifting slide rail 33, the lifting slider 32, the rotating shaft 34, and the bearing 35. The cooperation of the lifting slide rail 33 and the lifting slider 32 guides and limits the up and down movement of the thickness measuring roller 3, preventing it from deviating during up and down movement. The cooperation of the rotating shaft 34 and the bearing 35 allows the thickness measuring roller 3 to rotate freely, so that it can rotate freely on the surface of the leather and avoid affecting the transport of the leather.
[0027] The fixed plate 31 is also equipped with a displacement sensor for detecting the up and down movement of the thickness measuring wheel 3, or the thickness measuring wheel 3 has a built-in displacement sensor. The displacement sensor is designed to detect the up and down movement distance of the thickness measuring wheel 3, and thus the thickness of the leather passing through can be determined based on the up and down movement amplitude of the thickness measuring wheel 3.
[0028] A horizontally positioned profile 13 is also provided on the feeding frame 1, with the extension direction of the profile 13 perpendicular to the leather conveying direction. The fixing plate 31 is fixed to the profile 13 by bolts and nuts. A sliding groove for horizontal sliding of the bolts is also provided on the profile 13, and the sliding groove extends along the long axis of the profile 13. The design of the profile 13 is to cooperate with the fixing plate 31 and provide a moving base for the horizontal movement of the fixing plate 31, thereby facilitating the adjustment of the position of the thickness measuring roller 3. This allows for subsequent adjustment of the position of each thickness measuring roller 3 according to different sizes of leather, so as to detect the thickness of different parts of the leather.
[0029] A second protective frame 36 is provided on the outside of the thickness measuring wheel 3, enclosing the thickness measuring wheel 3. The second protective frame 36 also encloses the fixing plate 31, the lifting slide rail 33, the lifting slider 32, and the rotating shaft 34. The second protective frame 36 has a cavity for the thickness measuring wheel 3 to be installed and move up and down. The lower part of the thickness measuring wheel 3 extends out of the second protective frame 36 to allow it to smoothly contact the leather. An opening is provided at the bottom of the second protective frame 36 to accommodate the lower part of the thickness measuring wheel 3. The second protective frame 36 is designed to protect the thickness measuring wheel 3 from damage caused by external solid particles or to prevent it from affecting its normal rotation, ensuring that the thickness measuring wheel 3 can successfully detect the thickness of the leather.
[0030] The loading frame 1 is also equipped with a hygrometer for detecting the moisture content of the leather and a hardness meter for detecting the hardness of the leather. The hygrometer and hardness meter on the loading frame can detect the moisture content and hardness of the leather during loading, providing more detailed data for subsequent evaluation of the softening effect of the leather.
[0031] In subsequent practical applications, an additional controller and a host are required. The controller is connected to the camera, thickness measuring wheel 3, humidity meter, and hardness meter to receive data signals of the leather's outline, thickness, humidity, and hardness from the camera, thickness measuring wheel 3, humidity meter, and hardness meter, and transmits these data signals to the host. The host stores the leather's outline, thickness, humidity, and hardness. Simultaneously, the host calculates the number of leather pieces based on the outline data. That is, when the camera detects the outline data of leather, it counts one piece of leather, thus realizing the statistics of the number of leather pieces. This allows personnel to calculate the softening rate of the leather based on the outline, number, thickness, humidity, and hardness data, and to judge the softening effect of the oscillating softening machine accordingly.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
