[0031] Please see Figures 1 to 2 As shown, this utility model provides a leather bending container, comprising:
[0032] The workbench 1 and the bending assembly 2 disposed on the workbench 1 are provided. The bending assembly 2 includes a centering wheel 201, a limiting rod 202 and two columns 203. The columns 203 are vertically disposed on the workbench 1, the limiting rod 202 is horizontally disposed, and the two ends of the limiting rod 202 are respectively mounted on the columns 203. The centering wheel 201 is installed in the middle of the limiting rod 202 and is close to the workbench 1. A material passing area is formed between the centering wheel 201 and the corresponding column 203.
[0033] A shaping assembly is mounted on the worktable 1. The shaping assembly includes at least two shaping units. Each shaping unit includes two rollers 3 facing each other. The rotation axis of the rollers 3 is perpendicular to the worktable 1. A deformation area is formed between the two rollers 3. All the shaping units are arranged in a straight line.
[0034] For example, the container leather bending machine further includes a guide assembly, which includes two guide plates 4 facing each other. The guide plates 4 are disposed on the worktable 1, and a guide area is formed between the two guide plates 4. The guide area is located in the feeding direction of the bending assembly 2.
[0035] It should be noted that the purpose of setting the guide assembly is to pre-bend the leather by the guide assembly before the leather enters the bending assembly 2, so that the leather can smoothly enter the bending assembly 2, and the convenience is improved.
[0036] Illustratively, the guide plates 4 are inclined to be arranged, the lower ends of the two guide plates 4 are close to each other, and the upper ends are away from each other.
[0037] It should be noted that the purpose of inclining the guide plate 4 is that the leather can be supported by the corresponding guide plate 4 during the constraint of the guide plate 4, and the guide plate 4 can better support the leather, and the stability of the leather during conveying is improved.
[0038] Illustratively, the guide assembly, the bending assembly 2 and the shaping assembly are arranged in a straight line, and the bending assembly is located between the guide assembly and the shaping assembly.
[0039] It should be noted that when the leather is pretreated, the leather can be treated along a straight line to avoid bending and bending of the leather during treatment due to the arrangement of the components, and the influence on the shaping process of the leather is reduced.
[0040] Illustratively, the farther the shaping unit is from the bending assembly 2, the smaller the gap between the corresponding two rollers 3.
[0041] It should be noted that by gradually changing the gap between the rollers, the leather gradually receives the extrusion force of the rollers 3 after entering the shaping unit, so that the leather is shaped by the extrusion force.
[0042] Illustratively, the gap between the two rollers 3 corresponding to the shaping unit farthest from the bending assembly 2 is equal to the thickness of double-layer leather.
[0043] It should be noted that the shaping unit with the smallest gap is constrained to avoid damage to the leather due to the small gap between the rollers 3 corresponding to the shaping unit.
[0044] Illustratively, the height of the limiting rod 202 is half of the width of the leather.
[0045] It should be noted that the leather can ensure that the center wheel 201 is located in the middle of the width of the leather when passing through the bending assembly 2, and the deformation area is accurate and located on the same straight line.
[0046] Illustratively, the roller 3 is a bearing, the inner ring of the roller 3 is provided with a fixing rod, and the fixing rod is installed on the workbench 1.
[0047] It needs to be explained that the bearing is used for the roller 3, which can greatly reduce the cost, and due to the good rolling effect of the bearing, the large friction between the roller 3 and the leather is avoided when the leather passes, and the damage to the outer wall of the leather is caused.
[0048] Further, when the roller 3 is installed, the fixed rod 301 is fixedly arranged at the inner ring of the roller 3, so that the inner ring of the roller 3 is kept fixed relative to the fixed rod 301, and then the fixed rod 301 is arranged on the workbench 1.
[0049] It needs to be explained that the workbench 1 is also provided with an adjusting opening, and the fixed rod 301 is vertically arranged in the adjusting opening, and the two rollers 3 arranged opposite to each other can be adjusted in size according to the position of the fixed rod in the corresponding adjusting opening.
[0050] For example, after the fixed rod 301 is adjusted to the position, the fixed rod 301 adopts a screw rod, a nut can be arranged at the lower part of the workbench 1, and the position of the fixed rod 301 is fixed by cooperation of the nut and the screw rod, so that the position between the corresponding two rollers 3 does not change in the shaping process.
[0051] In one embodiment, the fixed rod 301 is also provided with a limiting ring, the limiting ring is fixedly connected with the fixed rod 301, and the limiting ring is used for axially limiting the fixed rod 301, so as to avoid the roller 3 directly contacting the workbench 1 and to avoid the friction between the roller 3 and the workbench 1 when the roller 3 rotates.
[0052] In summary, the leather bending device for the container of the utility model can guide the long strip-shaped leather into the bending assembly 2, press the center line in the length direction of the leather by the centering wheel 201, limit the two sides of the leather by the two side posts 203, make the cross section of the leather in the length direction present a U-shaped structure, guide the leather into the shaping assembly after the leather passes through the bending assembly 2, further shape the folded part of the leather by the multiple rollers 3, quickly and efficiently complete the pretreatment work, and reduce the damage to the leather.
[0053] The above embodiments only exemplarily illustrate the principle and effect of the utility model, and are not used for limiting the utility model. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and category of the utility model. Therefore, all equivalent modifications or changes completed by those skilled in the art without departing from the spirit and technical thought disclosed by the utility model should be covered by the claims of the utility model.
