Description

Technical Field

[0001] The present invention relates to a processing device, and more particularly to a leather processing device for making leather shoes. Background Art

[0002] After tanning, leather is transformed into soft, durable and non-perishable leather. Then, it is necessary to spray water or steam to make the leather evenly moisturized, and perform moisture regain and softening operations. After the moisture regain and softening operations, the leather needs to be tested for permeability to ensure that various parameters of the leather meet the standards. Finally, the finished leather can be used in leather shoe production. In actual production, moisture regain, softening and permeability tests are usually completed step by step, but this will greatly extend the production time. Therefore, a leather processing device for leather shoe production is needed, which can perform moisture regain, softening and permeability tests on leather.

[0003] In view of the above reasons, how to carry out moisture regain, softening and permeability testing of leather is exactly the problem considered in this application. Summary of the invention

[0004] In view of the shortcomings of the prior art, a leather processing device for leather shoe production is provided, which can perform moisture regain operation, softening operation and permeability test of leather.

[0005] To achieve the above-mentioned purpose, the following technical scheme is provided: a leather processing device for leather shoe production, comprising a frame, a spray liquid modulation component, a spray component, a protection component, a driving component, a softening component, a fixing component and a detection component, wherein the detection component, the softening component and the fixing component are all installed in the protection component, the softening component is used for softening the leather, the fixing component is used for fixing the leather, the spray liquid modulation component, the spray component and the protection component are all installed in the frame, and the spray liquid modulation component, the spray component and the protection component are connected;

[0006] When in use, the following steps are performed:

[0007] S1: Fix the leather to be treated in the fixing component, and select the softening component to be installed in the softening component;

[0008] S2: Install the fixing component and the softening component in the protection component;

[0009] S3: Start the spray liquid modulation component and add softening liquid and auxiliary agent to form a spray liquid;

[0010] S4: Start the spraying component, draw the spraying liquid from the spraying liquid modulation component and spray it into the protection component to perform the rehumidification operation;

[0011] S5: Start the detection component and record the start time of the first rehumidification operation;

[0012] S6: Start the driving component, and the driving component drives the stretching component to perform the stretching operation;

[0013] S7: The detection component records the time when the spray liquid is first detected, and compares it with the start time of the first rehumidification operation to form the first detection report;

[0014] S8: Collect the spray liquid at the bottom of the protection component and send the spray liquid into the spray component;

[0015] S9: After the rehumidification operation and the stretching operation are completed and the leather is dry, the rehumidification operation is started again. The detection component records the start time of the second rehumidification operation and the time when the spray liquid is detected for the second time, and forms a second detection report.

[0016] Furthermore, there are multiple numbers of the flexible components and the fixed components, and the fixed components and the flexible components are installed alternately in the protection component, and both ends are flexible components after installation.

[0017] In summary, the above technical solution has the following beneficial effects: the spray liquid is usually a mixture of a softening liquid and an auxiliary agent, and the rehumidification operation can be performed by spraying the spray liquid onto the leather surface. The softening liquid can use a surfactant, which is mainly used to reduce the surface tension of water, accelerate water absorption, and shorten the traditional standing time. The auxiliary agent usually uses glycerin or silicone oil, which is mainly used to lubricate the fiber gap and promote water penetration. In addition, through the connection of the spray liquid modulation component, the spray component and the protection component, a circulation system for recycling and reusing the spray liquid is realized, forming a closed-loop humidity control, reducing the discharge of chemical waste liquid, reducing the consumption of raw materials, allowing the spray liquid to penetrate evenly, and the closed environment of the protection component can ensure that the spray liquid will not leak, isolate external interference, and accurately control the humidity to avoid the risk of mildew or deformation;

[0018] The softening component achieves a squeezing or kneading effect through the installed softening parts, thereby destroying the rigid structure of the leather fiber. Combined with the spray liquid in the rewetting stage, it reduces the friction between the fibers and improves the ductility. The mechanized operation replaces the manual softening, and the processing speed is improved, which is suitable for mass production. For the leather set on the fixed component, both ends of the leather are softening parts, and the front and back sides are evenly stressed to avoid unilateral overload. The softening component can replace the softening parts to adapt to different leather types. The protective component and the fixed component can restrain the displacement of the leather to prevent excessive stretching or tearing;

[0019] The permeability test uses the detection component and the time difference method to evaluate the penetration rate. The first test record is the time when the rewetting starts and the time when the spray liquid is first detected. The initial permeability is reflected by calculating the time when the spray liquid penetrates into the bottom layer of the leather. The second test is repeated in the second rewetting after drying. The two time differences are compared to evaluate the impact of the softening process on the fiber structure. For example, a shortened time difference indicates that the fiber is more relaxed after softening and the permeability is improved. The predetermined time difference is used to determine whether the leather parameters are qualified. The leather permeability is objectively evaluated through the time difference data to avoid subjective experience errors. In addition, the detection component can be used to dynamically monitor the fiber state. The rewetting operation can be set to release the spray liquid in stages. In this way, the two test reports can quantify the permeability changes of the leather before and after the treatment of this stage, so as to determine whether the process causes fiber blockage or damage. For example, if the time difference increases significantly, the structure may collapse due to excessive softening. In this way, permeability abnormalities (such as local penetration delay) can be discovered at an early stage to avoid color spots or uneven finishing in subsequent processes (such as dyeing).

[0020] Compared with the traditional process, the present invention quantifies the data through non-contact dynamic detection, which is better than relying on manual observation or sampling destructive testing. The closed-loop spraying and softening are set to be carried out simultaneously in the protection component, and the chemical and mechanical forces are efficiently coordinated, which is better than the independent operation of rewetting and softening in steps to reduce production efficiency. In addition, in the rewetting operation, the spray liquid is recycled, which saves costs and is environmentally friendly, and reduces the cost of wastewater treatment;

[0021] The present invention provides a closed-loop spray system, which reduces waste through the circulation of spray liquid, ensures stable concentration, and improves environmental protection. The detection component automatically records time and generates reports to achieve full traceability of the process. The efficiency and effect are both improved through the combined operation of rehydration and softening combined with chemical softening and mechanical force. The detection component is used to detect permeability and monitor the process impact in real time to ensure that the finished product meets the standards. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. The same parts are represented by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "bottom surface" and "top surface", "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0040] Reference Figure 1As shown, the leather processing device for leather shoe production includes a frame 1, a spray liquid modulation component 2, a spray component 3, a protection component 4, a driving component 5, a softening component 6, a fixing component 7 and a detection component 8, wherein the detection component 8, the softening component 6 and the fixing component 7 are all installed in the protection component 4, the softening component 6 is used for softening the leather, the fixing component 7 is used for fixing the leather, the spray liquid modulation component 2, the spray component 3 and the protection component 4 are all installed in the frame 1, and the spray liquid modulation component 2, the spray component 3 and the protection component 4 are connected;

[0041] When in use, the following steps are performed:

[0042] S1: Fix the leather to be processed in the fixing component 7, and select the softening component to be installed in the softening component 6;

[0043] S2: Install the fixing component 7 and the softening component 6 in the protection component 4;

[0044] S3: Start the spray liquid preparation component 2 and add the softening liquid and the auxiliary agent to prepare the spray liquid;

[0045] S4: Start the spray component 3, draw the spray liquid from the spray liquid modulation component 2 and spray it into the protection component 4 to perform the rehumidification operation;

[0046] S5: Start the detection component 8 and record the start time of the first moisture regain operation;

[0047] S6: starting the driving component 5, and the driving component 5 drives the softening component 6 to perform the softening operation;

[0048] S7: The detection component 8 records the time when the spray liquid is first detected, and compares it with the start time of the first rehumidification operation to form a first detection report;

[0049] S8: Collect the spray liquid at the bottom of the protection component 4 and send the spray liquid to the spray component 3;

[0050] S9: After the rehumidification operation and the stretching operation are completed and the leather is dried, the rehumidification operation is started again. The detection component 8 records the start time of the second rehumidification operation and the time when the spray liquid is detected for the second time, and forms a second detection report.

[0051] Furthermore, there are multiple numbers of the softening components 6 and the fixing components 7, and the fixing components 7 and the softening components 6 are installed alternately in the protection component 4, and after installation, both ends are softening components 6.

[0052] The spraying liquid is usually a mixture of softening liquid and auxiliary agent. By spraying the spraying liquid onto the leather surface, the moisture regain operation can be carried out. The softening liquid can use surfactants, which are mainly used to reduce the surface tension of water, accelerate water absorption, and shorten the traditional static time. The auxiliary agent usually uses glycerol or silicone oil, which is mainly used to lubricate the fiber gaps, promote water penetration, and through the setting of the spraying liquid modulation component 2, the spraying component 3 and the protection component 4 being connected, a circulating system for liquid recovery and reuse of the spraying liquid is realized, forming a closed-loop humidity control, reducing chemical waste liquid discharge, reducing raw material consumption, enabling the spraying liquid to penetrate evenly, and the closed environment of the protection component 4 can ensure that the spraying liquid will not leak, isolating external interference, with accurate humidity control, avoiding the risk of mildew or deformation;

[0053] The softening and stretching component 6 realizes the squeezing or kneading effect through the installed softening and stretching parts, thereby destroying the rigid structure of the leather fibers. Combined with the spraying liquid in the moisture regain stage, it reduces the friction between the fibers and improves the ductility. By replacing manual softening and stretching with mechanized operation, the processing speed is increased, which is suitable for mass production. For the leather set on the fixed component 7, both ends of the leather are softening and stretching parts, and both the front and back sides are evenly stressed, avoiding unilateral overload. The softening and stretching component 6 can replace the softening and stretching parts, so as to adapt to different leather types. The protection component 4 and the fixed component 7 can restrain the displacement of the leather, preventing over-stretching or tearing;

[0054] The permeability detection uses the detection component 8 and the time difference method to evaluate the penetration rate. The first detection record is the moisture regain start time and the time when the spraying liquid is first detected. By calculating the time for the spraying liquid to penetrate to the bottom layer of the leather, the initial permeability is reflected. Then the second detection is repeated measurement during the secondary moisture regain after drying, and the time difference between the two times is compared to evaluate the influence of the softening and stretching process on the fiber structure. For example, if the time difference is shortened, it means that the fibers are more relaxed after softening and stretching, and the permeability is improved. By comparing with the predetermined time difference, it is judged whether the leather parameters are qualified. The leather permeability is objectively evaluated through the time difference data, avoiding subjective experience errors. In addition, the detection component 8 can be used to dynamically monitor the fiber state. The moisture regain operation can be set to release the spraying liquid in stages, so that the two detection reports can quantify the permeability change of the leather before and after the treatment at this stage, thereby judging whether the process causes fiber blockage or damage. For example, if the time difference increases significantly, it may be due to excessive softening and stretching resulting in structural collapse, which can detect abnormal permeability (such as local penetration delay) at an early stage and avoid color spots or uneven coating in subsequent processes (such as dyeing);

[0055] Compared with the traditional process, the present invention performs non-contact dynamic detection, quantifies the data, which is superior to relying on manual observation or sampling destructive testing. The closed-loop spraying and softening and stretching are carried out simultaneously in the protection component 4, and the chemical and mechanical forces cooperate efficiently, which is superior to the step-by-step independent operation of moisture regain and softening and stretching, reducing the production efficiency. In addition, in the moisture regain operation, the spraying liquid is recycled, saving costs and being environmentally friendly, reducing the cost of wastewater treatment;

[0056] The present invention provides a closed-loop spray system, which reduces waste through the circulation of spray liquid, ensures stable concentration, and improves environmental protection. The detection component 8 automatically records time and generates reports to achieve full traceability of the process. The efficiency and effect are both improved through the combined operation of rehydration and softening combined with chemical softening and mechanical force. The detection component 8 is used to detect permeability and monitor the process impact in real time to ensure that the finished product meets the standards.

[0057] Further, the protection component 4 includes a protection cover 41 and a protection barrel 42, the driving component 5 includes a first motor 51, a transmission belt 52, a transmission wheel 53, a transmission shaft 54, a fixed disk 55 and a contact strip 56, a plurality of through holes 551 are provided on the fixed disk 55, the protection cover 41 is detachably connected to the protection barrel 42, the first motor 51 is connected to the transmission belt 52, the transmission belt 52 is connected to the transmission wheel 53, the transmission shaft 54 ​​is fixedly connected to the dynamic transmission wheel 53, the fixed disk 55 is fixedly connected to the protection barrel 42, the fixed disk 55 is rotatably connected to the transmission shaft 54, the contact strip 56 is fixedly connected to the fixed disk 55, the fixing component 7 is installed on the contact strip 56, and the soft pulling component 6 is installed on the transmission shaft 54;

[0058] When the softening operation is started, the first motor 51 drives the transmission shaft 54 ​​to rotate through the transmission belt 52 and the transmission wheel 53, and the transmission shaft 54 ​​drives the softening assembly 6 to rotate.

[0059] The protection component 4 uses a barrel and a cover commonly used in the industry as a basis. The protection barrel 42 is fixed on the frame 1, so that the positions of the fixed plate 55 and the abutment strip 56 are also fixed. In this way, the fixed component 7 installed on the abutment strip 56 will not rotate, so that the leather is installed in a relatively fixed state. On this basis, the first motor 51 is used to drive the softening component 6 to rotate, so that the softening operation can be realized.

[0060] Furthermore, the protection component 4 also includes a first fixed connecting ring 43, a second fixed connecting ring 44, a first bolt 45, a first fixed connecting piece 46, a second fixed connecting piece 47 and an elastic connecting piece 48. The first fixed connecting ring 43 and the first fixed connecting piece 46 are both fixedly connected to the protection cover 41, the second fixed connecting ring 44 and the second fixed connecting piece 47 are both fixedly connected to the protection barrel 42, the first fixed connecting ring 43 is connected to the second fixed connecting ring 44 by the first bolt 45, and the first fixed connecting piece 46 is connected to the second fixed connecting piece 47 by the elastic connecting piece 48.

[0061] Due to the need for a relatively sealed environment, the protective cover 41 and the protective barrel 42 need to be tightly connected. The first fixed connecting ring 43, the second fixed connecting ring 44 and the first bolt 45 can be preliminarily connected, but this connection is a rigid connection. Since the softening operation and the rehumidification operation may generate high air pressure, in order to prevent the excessive air pressure from damaging the protective component 4, a certain amount of moving space needs to be reserved for the rigid connection, which is only used to limit the maximum moving distance. Therefore, the first fixed connector 46, the second fixed connector 47 and the elastic connector 48 are also required to be provided as soft connections. When the air pressure in the protective barrel 42 is too high, the protective cover 41 and the protective barrel 42 will be separated, allowing part of the internal gas to escape, thereby reducing the air pressure. After the air pressure returns to normal, the elastic connector 48 drives the protective cover 41 and the protective barrel 42 to be tightly connected again, wherein the elastic connector 48 can be made of springs and other components.

[0062] Furthermore, the protection component 4 also includes a first connecting pipe 421 and a second connecting pipe 422. The bottom of the protection barrel 42 is arranged in a slope. The first connecting pipe 421 is fixedly connected to the protection barrel 42 and is arranged at the lowest point of the slope. The detection component 8 is installed on the first connecting pipe 421, and the second connecting pipe 422 is fixedly connected to the protection barrel 42 and is connected to the spray component 3.

[0063] Through the slope at the bottom of the protective barrel 42, the spray liquid can be concentrated on the first connecting pipe 421 first, so that the detection component 8 can detect the spray liquid in the first time, reducing the detection error, and when the protective barrel 42 needs to be cleaned, the spray liquid or cleaning liquid can be quickly discharged. The second connecting pipe 422 is used for the circulation of the spray liquid, so there is no need to limit the installation position. The detection component 8 can adopt the existing technology, so it will not be elaborated here.

[0064] Furthermore, the softening component 6 includes a first rotating ring 61, a connecting disk 62, a mounting column 63 and a convex part 64. The connecting disk 62 is provided with a plurality of mounting holes 65. The mounting column 63 is installed in the mounting hole 65. The mounting column 63 and the convex part 64 are fixedly connected. The convex part 64 is used to realize the softening operation. The first rotating ring 61 and the connecting disk 62 are fixedly connected. The connecting disk 62 is installed on the transmission shaft 54.

[0065] Since different leathers and different needs require corresponding softening methods, the convex part 64 is a replaceable component. The appropriate shape can be selected according to actual process requirements, and then installed on the connecting disk 62 through the mounting column 63. When the connecting disk 62 is driven to rotate by the transmission shaft 54, the force point of the convex part 64 on the leather changes and is repeated continuously, thereby achieving a softening effect.

[0066] Furthermore, the softening component 6 also includes a first positioning ring 66 and a second positioning ring 67, which are fixedly connected to the upper and lower ends of the first rotating ring 61 respectively. The fixing component 7 includes a second rotating ring 71, a third rotating ring 72, a first contact block 73, a second contact block 74 and a second bolt 75. The second rotating ring 71 is provided with a first annular track 711 for accommodating the second positioning ring 67, and the first annular track 711 is provided with a first threaded hole 712 for connecting the second bolt 75. The third rotating ring 72 is provided with a second annular track 721 for accommodating the first positioning ring 66, and the second annular track 721 is provided with a second threaded hole 722 for connecting the second bolt 75. There are multiple first contact blocks 73 and second contact blocks 74, and multiple first contact blocks 73 are fixedly connected to the second rotating ring 71 in an annular array. Multiple second contact blocks 74 are fixedly connected to the third rotating ring 72 in an annular array. The first contact block 73 and the second contact block 74 are both in contact with the contact bar 56.

[0067] In order to make the best use of the leather, the leather is fixed by clamping the second rotating ring 71 and the third rotating ring 72, and the transmission shaft 54 ​​will also pass through the leather to prevent the leather from moving. The second rotating ring 71 and the third rotating ring 72 use the second bolt 75 as a connecting medium. In order to enhance the softening effect, the second rotating ring 71 and the third rotating ring 72 are required to be close to the first rotating ring 61 and can only rotate. Therefore, the first annular track 711, the second annular track 721, the first positioning ring 66 and the second positioning ring 67 are also provided as limiters, and the first threaded hole 712 and the second threaded hole 722 are hidden to prevent the second bolt 75 from accidentally popping out and scratching the leather. The first contact block 73 and the second contact block 74 are the same as the contact with the contact strip 56 to prevent the fixed component 7 from rotating.

[0068] Furthermore, the spray assembly 3 includes a liquid storage tank 31, a first hose 32, a water pump 33, a second hose 34 and a spray head 35. The second connecting pipe 422 is connected to the liquid storage tank 31, the liquid storage tank 31 is connected to the spray liquid modulation assembly 2, the two ends of the first hose 32 are respectively connected to the spray liquid modulation assembly 2 and the water pump 33, the two ends of the second hose 34 are respectively connected to the water pump 33 and the spray head 35, the spray head 35 is fixedly connected to the protective cover 41, and is used to spray the spray liquid toward the protective barrel 42.

[0069] The spray assembly 3 adopts a basic liquid flow system. The liquid storage tank 31 can also be used to recover the spray liquid. Most of the first hose 32 is exposed outside the frame 1, and the flow of the spray liquid can be directly observed through the first hose 32.

[0070] Furthermore, the spray assembly 3 also includes an external faucet 36 , which is fixedly connected to the spray head 35 and extends to the outside of the protective cover 41 .

[0071] For the purpose of temporarily adding chemical liquid, an external tap 36 is provided, so that additional chemical liquid can be added without stopping the circulation of the spray liquid, thereby improving the working efficiency.

[0072] Furthermore, the spray liquid modulation assembly 2 includes a second motor 21 and a stirrer 22 . The stirrer 22 is connected to the liquid storage tank 31 and to the water pump 33 via a first hose 32 . The second motor 21 is connected to the stirrer 22 .

[0073] Since the liquid mixing efficiency is low only by the water pump 33, an additional agitator 22 is required to assist in liquid mixing. The agitator 22 belongs to the prior art, so it will not be described in detail here.

[0074] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
