Description

Technical Field

[0001] This invention relates to the field of regenerated leather technology, and more specifically, to a device for testing the physical properties of regenerated leather. Background Technology

[0002] Regenerated leather is a sheet material made from scraps of genuine leather. It retains the fiber structure of genuine leather, has a soft and flexible feel, and is breathable. It can be perforated, stitched, and embossed like genuine leather, but achieves zero fur and zero chromium emissions. Each ton of product can reduce carbon emissions by about three tons and wastewater by 90%. The price is more than 30% lower than that of top-grain genuine leather. It has uniform density, no part-specific differences, and high cutting utilization. It is widely used in shoe linings, belts, handbags, packaging, car door panels, and furniture decoration, and has the advantages of being environmentally friendly, lightweight, resource-recyclable, and cost-effective.

[0003] The physical properties of recycled leather need to be tested, such as flexural strength, abrasion resistance, tensile strength, and peel strength. Most physical property tests simply require clamping the leather onto the corresponding equipment for testing. However, peel strength testing requires placing test tape on the leather surface, heating and pressing the leather and tape together, and finally testing the peel strength between the leather and tape. The entire testing process requires the use of multiple devices, and staff need to operate and transfer the leather multiple times, making the peel strength testing process cumbersome, time-consuming, and inefficient. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a device for testing the physical properties of regenerated leather.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a physical property testing device for regenerated leather, comprising a housing and a heat sealing mechanism; An operating port is opened on one side of the housing. Linear modules are respectively installed on the inner sidewalls of both sides of the housing. Base blocks are fixedly connected to the sliders of the two linear modules. Multiple first guide rods are fixedly connected between the two base blocks. The multiple first guide rods are parallel to each other. A support is fixedly connected to the multiple first guide rods. A first electric cylinder is installed on the support. A first cross arm is fixedly connected to the piston rod of the first electric cylinder. The first cross arm is slidably connected to the multiple first guide rods. A second cross arm is provided on the side of the first cross arm near the support. The second cross arm is slidably connected to the multiple first guide rods. A tension sensor is installed between the second cross arm and the support. The first and second cross arms are respectively provided with clamping components, and the two clamping components are used to clamp the test tape and the leather respectively; The heat-sealing mechanism is mounted on the housing and is used to heat and press the test tape and leather together.

[0006] A further technical solution of this application: The two clamping components each include a folding plate seat, a lead screw, a handle, a movable clamping plate, and a fixed clamping plate. The two folding plate seats are fixedly connected to the first cross arm and the second cross arm, respectively. A lead screw is threaded onto the folding plate seat. A handle is fixedly connected to one end of the lead screw, and a movable clamping plate is rotatably connected to the other end of the lead screw. The movable clamping plate rubs against the folding plate seat. A fixed clamping plate is provided on the side of the movable clamping plate away from the lead screw, and the fixed clamping plate is fixedly connected to the folding plate seat.

[0007] A further technical solution of this application: The heat sealing mechanism includes a base, a second guide rod, a second electric cylinder, a hot press plate, and a support plate. Two bases are symmetrically arranged and both are disposed inside the housing. Multiple second guide rods are fixedly connected to the two bases respectively. The multiple second guide rods are slidably connected to the housing. Second electric cylinders are installed on the two side walls of the housing respectively. The piston rods of the two second electric cylinders are fixedly connected to the two bases respectively. Hot press plates and support plates are fixedly connected to the side walls of the two bases that are close to each other respectively.

[0008] A further technical solution of this application: a third electric cylinder is installed on the sidewalls of the two bases that are far apart from each other. The piston rods of the two third electric cylinders pass through the two bases and are fixedly connected to roller frames. Rollers are rotatably connected to the two roller frames.

[0009] A further technical solution of this application is as follows: each of the roller frames is fixedly connected with a plurality of third guide rods, and the plurality of third guide rods are slidably connected to the base.

[0010] A further technical solution of this application: an exhaust port is opened at the upper end of the housing, a fan is installed on the inner top wall of the housing, and the air outlet of the fan is connected to the exhaust port.

[0011] A further technical solution of this application: A transparent baffle is fixedly connected to the side wall of the housing where the operation port is opened, and the transparent baffle covers the two bases.

[0012] A further technical solution of this application: recessed platforms are integrally formed on both side walls of the housing, and the two second electric cylinders are respectively installed on the side walls of the two recessed platforms.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. During the entire testing process, staff only need to use two clamping components to hold one end of the test tape and one end of the leather before testing, and remove the test tape and leather after testing. This effectively simplifies the peel performance testing process, shortens the testing time, and improves testing efficiency. 2. After the two clamping components move above the rollers, the two rollers can be pushed closer to each other by two third electric cylinders, so that the two rollers clamp the test tape and leather. As the test tape and leather continue to move upward, they can be pre-pressed by the clamping action of the two rollers. 3. The fan can accelerate the cooling of the test tape and leather.

[0020] Reference Figures 1 to 6 In one embodiment of this application, a physical property testing device for recycled leather includes a housing 1 and a heat sealing mechanism; An operation port 2 is provided on one side of the housing 1, such as... Figure 1 Workers load and unload materials at the operating port 2. Linear modules 3 are installed on the inner walls of both sides of the housing 1. Base blocks 4 are fixedly connected to the sliders of the two linear modules 3, such as... Figure 2The slider on the linear module 3 can drive the base block 4 to move. The operating principle of the linear module 3 is existing technology and will not be described in detail here. Multiple first guide rods 5 are fixedly connected between the two base blocks 4. The multiple first guide rods 5 are parallel to each other. A support platform 6 is fixedly connected to the multiple first guide rods 5. A first electric cylinder 7 is installed on the support platform 6. A first horizontal arm 8 is fixedly connected to the piston rod of the first electric cylinder 7. The first horizontal arm 8 is slidably connected to the multiple first guide rods 5. A second horizontal arm 9 is provided on the side of the first horizontal arm 8 near the support platform 6. The second horizontal arm 9 is slidably connected to the multiple first guide rods 5. A tension sensor 10 is installed between the second horizontal arm 9 and the support platform 6. Clamping components are respectively provided on the first horizontal arm 8 and the second horizontal arm 9, and the two clamping components are used to clamp the test tape and the leather respectively; like Figure 2 and Figure 3 The initial position of the clamping components is below the heat sealing mechanism. Before feeding, the test tape is first attached to the leather, and then the two clamping components clamp one end of the test tape and the leather respectively. The heat sealing mechanism is mounted on the housing 1, and is used to heat and press the test tape and leather together. like Figure 2 and Figure 3 The sliders of the two linear modules 3 always remain at the same height, thereby simultaneously driving the two base blocks 4 to rise and fall. The two base blocks 4 drive multiple first guide rods 5 to rise and fall. The multiple first guide rods 5 can drive the first horizontal arm 8 and the second horizontal arm 9 to rise and fall. The first horizontal arm 8 and the second horizontal arm 9 can drive the test tape and leather to rise and fall through the clamping components on them. First, the test tape and leather are moved upward to the heat sealing mechanism. The heat sealing mechanism heats and presses the test tape and leather together. After the heat sealing is completed, the test tape and leather are moved upward to the top of the heat sealing mechanism. After the test tape and leather cool down, the first electric cylinder 7 pushes the first horizontal arm 8 to slide along multiple first guide rods 5 away from the second horizontal arm 9. The two clamping components on the first horizontal arm 8 and the second horizontal arm 9 will move away from each other, thereby peeling off the test tape and leather. The tensile force value borne by the second horizontal arm 9 during the peeling process is monitored by the tensile force sensor 10 to complete the test of the leather peeling performance. Throughout the testing process, staff only need to use two clamping components to hold one end of the test tape and one end of the leather before testing, and remove the test tape and leather after testing. This effectively simplifies the peel performance testing process, shortens the testing time, and improves testing efficiency.

[0021] In a preferred embodiment of this application, the two clamping assemblies each include a folding plate seat 11, a lead screw 12, a handle 13, a movable clamping plate 14, and a fixed clamping plate 15. The two folding plate seats 11 are fixedly connected to the first cross arm 8 and the second cross arm 9, respectively. The lead screw 12 is threaded onto the folding plate seat 11. One end of the lead screw 12 is fixedly connected to the handle 13, and the other end of the lead screw 12 is rotatably connected to the movable clamping plate 14. The movable clamping plate 14 rubs against the folding plate seat 11. The fixed clamping plate 15 is provided on the side of the movable clamping plate 14 away from the lead screw 12, and the fixed clamping plate 15 is fixedly connected to the folding plate seat 11. like Figure 4 The handle 13 facilitates the rotation of the lead screw 12, which in turn drives the movable clamp 14 to move. When the movable clamp 14 moves toward the fixed clamp 15, it can clamp the test tape or leather.

[0022] As a preferred embodiment of this application, the heat sealing mechanism includes a base 16, a second guide rod 17, a second electric cylinder 18, a hot press plate 19, and a support plate 20. Two bases 16 are symmetrically arranged and are both disposed inside the housing 1. Multiple second guide rods 17 are fixedly connected to the two bases 16 respectively, and the multiple second guide rods 17 are slidably connected to the housing 1. The two side walls of the housing 1 are respectively equipped with second electric cylinders 18, and the piston rods of the two second electric cylinders 18 are fixedly connected to the two bases 16 respectively. The hot press plate 19 and the support plate 20 are fixedly connected to the side walls of the two bases 16 that are close to each other. The hot press plate 19 is a prior art technology, which has an electric heating rod or electric heating tube embedded inside and is equipped with a thermocouple for temperature control, and will not be described in detail here. like Figure 2 and Figure 5 The two bases 16 are supported by multiple second guide rods 17 respectively, and the piston rods of the two second electric cylinders 18 can drive the two bases 16 to move respectively. First, the two bases 16 are moved away from each other to their initial positions by the two second electric cylinders 18. At this time, the distance between the two bases 16 is large, and the two clamping components can drive the test tape and leather through the space between the two bases 16. When the test tape and leather move upward between the two bases 16, the two second electric cylinders 18 drive the two bases 16 to move closer to each other. The two bases 16 respectively drive the hot press plate 19 and the support plate 20 on them to move closer to each other. The hot press plate 19 and the support plate 20 can then clamp and squeeze the test tape and leather, thereby heating and pressing the test tape and leather together.

[0023] As a preferred embodiment of this application, a third electric cylinder 21 is installed on the sidewalls of the two bases 16 that are far apart from each other. The piston rods of the two third electric cylinders 21 pass through the two bases 16 and are fixedly connected to roller frames 22. Rollers 23 are rotatably connected to the two roller frames 22 respectively. like Figure 2 and Figure 5 When the two clamping components move above the roller 23, the two rollers 23 can be pushed closer to each other by the two third electric cylinders 21, so that the two rollers 23 clamp the test tape and leather. As the test tape and leather continue to move upward, the test tape and leather can be pre-pressed under the clamping action of the two rollers 23. Before the heat sealing mechanism heats and presses the test tape and leather, the two third electric cylinders 21 drive the two rollers 23 away from each other and reset.

[0024] In a preferred embodiment of this application, each roller frame 22 is fixedly connected with a plurality of third guide rods 24, and the plurality of third guide rods 24 are slidably connected to the base 16, such as Figure 5 The roller frame 22 is supported by multiple third guide rods 24, and the roller frame 22 supports the roller 23.

[0025] In a preferred embodiment of this application, the upper end of the housing 1 has an exhaust port 25, and a fan 26 is installed on the inner top wall of the housing 1. The outlet of the fan 26 is connected to the exhaust port 25. Figure 1 The cooling of the test tape and leather can be accelerated by the fan 26.

[0026] In a preferred embodiment of this application, a transparent baffle 27 is fixedly connected to the side wall of the housing 1 where the operation port 2 is located. The transparent baffle 27 covers the two bases 16, such as... Figure 1 The transparent baffle 27 can be made of materials such as acrylic or tempered glass, and can provide protection without affecting observation.

[0027] As a preferred embodiment of this application, recessed platforms 28 are integrally formed on both side walls of the housing 1, and the two second electric cylinders 18 are respectively installed on the side walls of the two recessed platforms 28, making the structure of the entire device more compact.

[0028] In addition to the above-mentioned technical solutions, the electric cylinder of this application may also use linear drive components such as hydraulic cylinders, and this application does not limit it.

[0029] Working principle: First, the test tape and leather are moved upward to the heat sealing mechanism. The heat sealing mechanism heats and presses the test tape and leather together. After heat sealing, the test tape and leather are moved upward again to the top of the heat sealing mechanism. After the test tape and leather cool down, the first electric cylinder 7 pushes the first horizontal arm 8 to slide along multiple first guide rods 5 away from the second horizontal arm 9. The two clamping components on the first horizontal arm 8 and the second horizontal arm 9 will move away from each other, thereby peeling the test tape and leather. The tensile force sensor 10 monitors the tensile force value borne by the second horizontal arm 9 during the peeling process, thus completing the test of the leather peeling performance.

[0030] It should be noted that all electrical components appearing in this application are connected to an external main controller and 220V AC mains power. The main controller can be a processor, alarm module, or drive module, etc., to control conventional known devices. All standard parts used in this application can be purchased from the market.
