Description

Technical Field

[0001] The utility model relates to the technical field of leather product processing, in particular to a leather dyeing device. Background Art

[0002] Leather is a fabric made from animal skins and can be used to make clothing, accessories, furniture, vehicle seats, etc. With the development of technology, in addition to natural leather, artificial leather has also appeared. Whether it is natural leather or artificial leather, in order to increase the beauty before being processed into products, the leather is usually dyed into various colors, and patterns are subsequently printed on the leather surface to increase the beauty of the leather products. Special leather dyeing equipment is required when dyeing the leather.

[0003] A microfiber leather dyeing device with application number 202321239596.1 includes a dyeing box, wherein a feed port and a discharge port are respectively provided on the top of both sides of the dyeing box, and a fixed roller is installed inside the dyeing box through a bearing. The microfiber leather dyeing device can drive the movable roller to move upward or downward by rotating the handle. When the movable roller moves upward, the movable roller can be moved to the top of the dyeing box, which is convenient for manual passage of the leather through the bottom of the movable roller. When the movable roller moves downward, the leather passing through the bottom of the movable roller can be pressed into the inside of the dye, which is convenient for coloring the leather; by pulling the pull plate, the two pressing rollers can be moved away from each other, and the compression spring can be compressed, so that leather of different thicknesses can pass between the two pressing rollers, and under the pressure of the compression spring, the two pressing rollers are tightly pressed against the leather, so that when the leather passes through the two pressing rollers, excess dye on the leather can be scraped off.

[0004] This technical solution uses a handwheel to drive the transmission shaft with a bevel gear to rotate, and then the bevel gears are engaged to rotate the two screws to control the lifting and lowering of a guide roller to facilitate the leather passing through the device. However, the dye will inevitably solidify after being used for too long, resulting in a layer of dye coating on the surface of the screw and the inside of the threaded sleeve. As time goes by, the dye layer gradually accumulates and thickens, reducing the gap between the screw and the sleeve, increasing the resistance to structural movement, and making the operation more labor-intensive. Utility Model Content

[0005] Based on this, the purpose of the present invention is to provide a leather dyeing device to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a leather dyeing device, comprising a device body, an adjustment component is arranged inside the device body, and the adjustment component includes a swing frame, the outer surface of the swing frame is connected to a handle, and one side of the handle passes through a limit frame, the limit frame is respectively connected to a pull rope and a spring, and the outer surface of the device body is connected to a limit ring.

[0007] By adopting the above technical solution, the swing frame is rotated upward by pressing the handle downward, so that the second guide roller in the swing frame is extended from the device, so that the staff can pass the leather material through. Since the length of the handle is greater than the height of the swing frame, a labor-saving lever is formed to reduce the operating effort. Thereafter, the handle is lifted to rotate the swing frame downward to reset it so that the dyeing work can be carried out. The operation is time-saving, labor-saving and convenient. While operating the handle, the pull rope can be pulled to separate the limit frame from the limit ring. After operating the handle, the pull rope is released to allow the spring to drive the limit frame to counteract the limit ring. The friction between the limit frame and the limit ring prevents the swing frame and the handle from rotating at will.

[0008] Furthermore, the swing frame is rotatably connected to the device body, and the length of the handle is greater than the height of the swing frame.

[0009] By adopting the above technical solution, the swing frame is rotated upward by pressing the handle downward, and because the length of the handle is greater than the height of the swing frame, a labor-saving lever is formed to reduce operating effort.

[0010] Furthermore, one side of the limit frame is arc-shaped, and the limit frame is slidably connected to the handle.

[0011] By adopting the above technical solution, force is applied to the limit frame through the pull rope, and the limit frame is retracted into the handle under force and separated from the limit ring, and the spring is compressed.

[0012] Furthermore, two limiting frames are provided, and the two limiting frames are mirror-imaged.

[0013] By adopting the above technical solution, the contact area between the limiting frame and the limiting ring is increased by providing the two limiting frames, thereby increasing the friction force between the limiting frame and the limiting ring.

[0014] Furthermore, the limiting frame abuts against the limiting ring.

[0015] By adopting the above technical solution, the spring drives the limit frame to reset and extend out of the handle, so that the limit frame and the limit ring are offset against each other, and the friction between the two prevents the swing frame and the handle from rotating randomly.

[0016] Furthermore, the pull rope is a steel wire rope, and a through hole for the pull rope to pass through is provided on one side of the outer surface of the limiting frame.

[0017] By adopting the above technical solution, the steel wire rope is wear-resistant and has strong tensile strength, which facilitates the transmission of force, so that the position of the limit frame can be controlled by applying force to the limit frame through the pull rope.

[0018] Furthermore, the handle is fixedly connected to the swing frame.

[0019] By adopting the above technical solution, the staff presses down the handle to rotate the swing frame upward, and the staff lifts up the handle to rotate the swing frame downward to reset the operation.

[0020] Furthermore, first guide rollers are connected to the upper sides of both sides of the device body, second guide rollers are connected to both sides inside the device body and the lower side inside the swing frame, and leather material is connected between the first guide roller and the second guide roller.

[0021] By adopting the above technical solution, the staff rolls up the leather material through the winding equipment to make the leather material start to move, or uses other equipment to make the leather material move. After the leather material moves, it is guided through the first guide roller and the second guide roller to pass through the dye. At this time, the leather material absorbs the dye and is dyed to complete the work.

[0022] Furthermore, a handle is passed through the top of the handle, and one end of the pull rope is connected to the handle.

[0023] By adopting the above technical solution, the staff grasps the handle and slides the handle to the right. After the handle moves to the right, the staff pulls the pull rope, thereby applying force to the limit frame through the pull rope.

[0024] Furthermore, the handle is slidably connected to the handle.

[0025] By adopting the above technical solution, the staff grasps the handle and slides it to the right. After the handle moves to the right, the staff pulls the pull rope to retract the limit frame to end the limit.

[0026] In summary, the present invention has the following beneficial effects:

[0027] The utility model adjusts the setting of the component and presses down the handle to rotate the swing frame upward, so that the second guide roller in the swing frame extends from the device, so that the staff can pass the leather material through. Since the length of the handle is greater than the height of the swing frame, a labor-saving lever is formed to reduce the operating effort. Thereafter, the handle is lifted to rotate the swing frame downward to reset it so that the dyeing work can be carried out. The operation is time-saving, labor-saving and convenient. While operating the handle, the pull rope can be pulled to separate the limit frame from the limit ring. After operating the handle, the pull rope is released to allow the spring to drive the limit frame to counteract the limit ring, and the friction between the limit frame and the limit ring prevents the swing frame and the handle from rotating at will. The operation is time-saving and labor-saving, and the active point of the structure is far away from the dye to prevent the dye from adhering to the reduced movement gap and the phenomenon of increased movement resistance.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0034] The following describes an embodiment of the present invention based on its overall structure.

[0035] Example 1:

[0036] A leather dyeing device, such as Figures 1-4 As shown, the device comprises a main body 1 , and an adjustment component 5 is provided inside the main body 1 .

[0037] Specifically, the adjustment component 5 includes a swing frame 501 connected to the upper part of the device body 1, the swing frame 501 is rotatably connected to the device body 1, and a handle 502 is fixed to the outer surface of the swing frame 501. Pressing the handle 502 downward causes the swing frame 501 to rotate upward; the length of the handle 502 is greater than the height of the swing frame 501, forming a labor-saving lever to reduce operating effort; one side of the handle 502 passes through the limit frame 506, one side of the limit frame 506 is arc-shaped, and the limit frame 506 is slidably connected to the handle 502, and the limit frame 506 is retracted into the handle 502 by force and separated from the limit ring 504 to end the limit of the handle 502; the limit frame 506 There are two limit frames 506, which are mirror-imaged to increase the contact area and thus the friction force. The limit frames 506 are internally connected with a pull rope 505 and a spring 507, respectively. The pull rope 505 is a steel wire rope, and a through hole for the pull rope 505 to pass through is provided on one side of the outer surface of the limit frame 506. The pull rope facilitates the retraction of the limit frame 504 into the handle 502 to end the limit, and the spring facilitates the driving of the limit frame 504 to extend from the handle 502 for limit. The outer surface of the device body 1 is connected with a limit ring 504, and the limit frame 506 abuts against the limit ring 504, and the friction between the two prevents the swing frame 501 and the handle 502 from rotating at will.

[0038] See Figure 1-Figure 3In the above embodiment, first guide rollers 2 are connected to the upper sides of the device body 1, second guide rollers 3 are connected to the inner sides of the device body 1 and the lower side of the swing frame 501, and leather material 4 is connected between the first guide roller 2 and the second guide roller 3. After the leather material 4 moves, it is guided through the dye by the first guide roller 2 and the second guide roller 3. At this time, the leather material 4 absorbs the dye and is dyed, thereby completing the work.

[0039] Example 2:

[0040] On the basis of the above-mentioned embodiment 1, although the operation can be time-saving and labor-saving by setting the adjustment component 5, and the active point of the structure is far away from the dye to avoid the phenomenon of dye adhesion, reducing the movement gap and increasing the movement resistance; but one hand is required to pull the pull rope 505 and the other hand is required to operate the handle 502, and the operation is relatively cumbersome; now by setting the handle 503, one hand can pull the pull rope 505 and operate the handle 502 at the same time.

[0041] See Figure 1 and Figure 3 In the above embodiment, a handle 503 passes through the top of the handle 502, one end of the pull rope 505 is connected to the handle 503, and the handle 503 is slidably connected to the handle 502. The staff grabs the handle 503 and slides the handle 503 to the right, and then the staff presses down or lifts the handle 502 through the handle 503.

[0042] The implementation principle of the present utility model is as follows: first, the staff pours dye into the device body 1, then the staff grabs the handle 503 and slides the handle 503 to the right. After the handle 503 moves to the right, the staff pulls the pull rope 505, thereby applying force to the limit frame 506 through the pull rope 505. At this time, the limit frame 506 is retracted into the handle 502 under force and separated from the limit ring 504 and the spring 507 is compressed. Then the staff presses the handle 502 downward through the handle 503 to make the swing frame 501 rotate upward, thereby making the swing frame 50 1 extends from the device, and because the handle 502 is longer than the swing frame 501, a labor-saving lever is formed to reduce the operating effort. Then the staff member releases the handle 503 and the spring 507 drives the limit frame 506 to return and extend from the handle 502, so that the limit frame 506 and the limit ring 504 are offset. The friction between the two prevents the swing frame 501 and the handle 502 from rotating at will. Then the staff member passes the leather material 4 through the first guide roller 2 and the second guide roller 3.

[0043] After the leather material 4 is put on, the staff member grabs the handle 503 and slides the handle 503 to the right. After the handle 503 moves to the right, the pull rope 505 is pulled, thereby applying force to the limit frame 506 through the pull rope 505. At this time, the limit frame 506 is retracted into the handle 502 by the force, separated from the limit ring 504 and the spring 507 is compressed. Then the staff member lifts the handle 503 to make the swing frame 501 rotate downward and reset to start dyeing. Then the staff member lets go and no longer holds the handle 503. At this time, the spring 507 drives the limit frame 506 to reset and extend out of the handle 502, so that the limit frame 506 is offset against the limit ring 504, and the friction between the two prevents the swing frame 501 and the handle 502 from rotating at will. At this time, the staff member rewinds the leather material 4 through the winding device to make the leather material 4 start to move, or uses other equipment to make the leather material 4 move. After the leather material 4 moves, it is guided through the first guide roller 2 and the second guide roller 3 to pass through the dye. At this time, the leather material 4 absorbs the dye and is dyed, thereby completing the work.
