[0024] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] like Figure 1-Figure 7 An embodiment of the present invention provides a device for winding and bending a strap, comprising a frame 1, on which are arranged a rotating fork 6, a pressing head 7, a fork driving mechanism for driving the rotating fork 6 to rotate and translate, and a pressing head driving mechanism 8 for driving the pressing head 7 to rise and fall; the frame 1 is also arranged with a support plate 4, and the support plate 4 is connected to a support plate driving mechanism 5 for driving it to translate and switch between a supporting position and an avoidance position. In the supporting position, the support plate 4 is located directly below the pressing head 7; the supporting surface of the support plate 4 is a plane or the support plate 4 has a concave structure and / or a convex structure, so that it can cooperate with the pressing head 7 to make the strap roll 10 have at least two bending locations.

[0026] The rotating fork 6 is used to insert the strap, even if the strap enters the fork groove of the rotating fork 6, the strap can be wound up by rotating the rotating fork 6. Figure 2 and Figure 3 The rotating fork 6 comprises a base connected to the fork driving mechanism and two fork plates connected to the base, the plate surfaces of the two fork plates are parallel, the base can be cylindrical or other shapes, the two fork plates are arranged opposite to each other, and can be surrounded by the base to form the fork groove. It can be understood that in the initial state, the plate surfaces of the two fork plates are parallel to the belt surface of the strap to be wound, for example, when the strap is placed horizontally, the plate surfaces of the two fork plates are parallel to the horizontal plane, so as to facilitate the insertion of the strap.

[0027] The fork drive mechanism includes a rotation drive unit 31 for driving the rotating fork 6 to rotate and a translation drive unit 32 for driving the rotating fork 6 to translate. In one embodiment, the rotation drive unit 31 is arranged on the translation drive unit 32. For example, the translation drive unit 32 includes a translation slide, and a corresponding translation slide is arranged on the frame 1. The rotation drive unit 31 is arranged on the translation slide, and the translation slide can be driven by a cylinder, a hydraulic cylinder, or a motor + screw mechanism. The rotation drive unit 31 can use a conventional rotation drive device such as a motor.

[0028] The above-mentioned ram driving mechanism 8 can adopt a linear driving device such as a cylinder, a hydraulic cylinder or a motor + screw mechanism, and the specific structure is not repeated here. Obviously, the upper stroke end / upper limit position of the ram 7 is located above the rotating fork 6 and the support plate 4.

[0029] The support plate driving mechanism 5 can also adopt a linear driving device such as a cylinder, a hydraulic cylinder or a motor + screw mechanism, and it can also adopt a translation slide as a carrier of the support plate 4, and a corresponding translation slide rail can be arranged on the frame 1. The support plate driving mechanism 5 is used to drive the support plate 4 to move between the support position and the avoidance position. The main purpose is to return the support plate 4 to the avoidance position after the strapping roll 10 is pressed and bent, so that the strapping roll 10 can fall into the waste bin 9 below under its own weight.

[0030] More preferably, if Figure 1 and Figure 2The frame 1 is provided with two vertical limit plates 2 for limiting the horizontal shaking of the strap. The two vertical limit plates 2 are arranged in parallel and the distance between them is not less than the width of the strap. Preferably, the distance between the two vertical limit plates 2 is slightly larger than the width of the strap, which ensures smooth winding of the strap while limiting the horizontal shaking of the strap. It can be understood that the so-called horizontal shaking refers to the movement in the width direction of the strap, and the plate surfaces of the two vertical limit plates 2 are perpendicular to the translation direction of the rotating fork 6. In order to avoid interference with the translational movement of the rotating fork 6 and the support plate 4, it is necessary to set a clearance hole on the corresponding vertical limit plate 2, specifically: the rotating fork 6 is arranged on the outer side of one of the vertical limit plates 2 and a first clearance hole for the rotating fork 6 to pass through is provided on the vertical limit plate 2, and the support plate 4 is arranged on the outer side of one of the vertical limit plates 2 and a second clearance hole for the support plate 4 to pass through is provided on the vertical limit plate 2; when the fork driving mechanism and the support plate driving mechanism 5 are arranged on the same side, the above-mentioned first clearance hole and the second clearance hole are correspondingly opened on the same vertical limit plate 2, and when the fork driving mechanism and the support plate driving mechanism 5 are arranged on different sides, the above-mentioned first clearance hole and the second clearance hole are respectively located on the two vertical limit plates 2.

[0031] More preferably, if Figure 3 The frame 1 is provided with two horizontal supporting plates 11 for supporting the straps, which are arranged in the same plane and arranged on both sides of the translation channel of the rotating fork 6. The two horizontal supporting plates 11 are not only used to place the straps in the initial state, but also can limit the unwound part during the strap winding process to ensure the smooth winding of the straps. It can be understood that when the two fork plates of the rotating fork 6 are in the initial state, the plate surface of the horizontal supporting plates 11 is located above the plate surface of the lower fork plate or the two are flush, so as to ensure that the straps can enter the fork groove of the rotating fork 6.

[0032] The support plate 4 is used to support the strapping roll 10 so as to cooperate with the downward pressing action of the pressing head 7 to achieve the bending operation of the strapping roll 10 .

[0033] In one embodiment, if Figure 5 When the support surface of the support plate 4 is a plane, the pressing surface of the pressure head 7 is also a plane, and the plane lengths of the support surface and the pressing surface are not less than half of the circumference of the strapping roll 10. For example, the support plate 4 is a flat plate, and the pressure head 7 is also a flat plate; obviously, it is better that the above-mentioned support surface and the pressing surface are parallel to the horizontal plane. Figure 5By driving the pressure head 7 close to the support plate 4, the strapping roll 10 can be bent and deformed, specifically, the strapping roll 10 is deformed from a roughly circular shape to a plate shape, wherein a large plastic deformation can be achieved at both ends of the plate-shaped strapping roll 10, and it can be ensured that the strapping roll 10 does not rebound or rebounds slightly after deformation. In the waste bin 9, the plate-shaped strapping rolls 10 can be stacked in sequence.

[0034] In one embodiment, if Figure 3 , when the support plate 4 has an upward convex structure, at least one ridge 41 is provided on the support surface of the support plate 4, and the length direction of each ridge 41 is parallel to the translation direction of the support plate 4; the bottom end of the pressure head 7 is provided with at least one clearance groove that matches the shape of the ridge 41, and when the support plate 4 slides to its supporting position, each ridge 41 is located directly below each clearance groove in a one-to-one correspondence. Preferably, there are multiple ridges 41, and the arrangement direction of each ridge 41 is perpendicular to the translation direction of the support plate 4; in one embodiment, the number of the ridges 41 is two; the ridges 41 may be in an inverted V shape or an inverted U shape. The top of the ridge 41 is preferably adapted to fit the shape of the clearance groove. Since a strap needs to be sandwiched between the support plate 4 and the pressure head 7, the depth of the clearance groove can be designed to be smaller than the protruding height of the ridge 41. Further preferably, the protruding heights of each ridge 41 are the same. Figure 4 When two convex ridges 41 are provided, after the strapping roll 10 is bent and deformed by the cooperation of the pressing head 7 and the supporting plate 4, the formed strapping roll 10 is roughly M-shaped, and there are up to 8 bends in the strapping roll 10, among which the bends formed by the convex ridges 41 can at least form a large plastic deformation.

[0035] In one embodiment, if Figure 6 When the support plate 4 has a concave structure, the concave structure includes a first guide groove opened on the support plate 4, and both side groove walls of the first guide groove have inclined surface sections 42. Both side inclined surface sections 42 extend downward from the support surface of the support plate 4 and enclose to form a saddle mouth that is wide at the top and narrow at the bottom. In the support position, the pressure head 7 is located directly above the first guide groove. The above two inclined surface sections 42 can form a V-shaped saddle, which can stably support the strapping roll 10 and play a role in bending and guiding when the strapping roll 10 is pressed by the pressure head 7; optionally, Figure 6 The first guide groove also penetrates the bottom of the support plate 4, dividing the support plate 4 into two parts, and the deformed strapping roll 10 can partially leak out from the bottom end of the first guide groove, so that the strapping roll 10 can be deformed to a greater extent. Figure 6 After the pressure head 7 cooperates with the support plate 4 to bend and deform the strap roll 10, the formed strap roll 10 is roughly in the shape of a boomerang. The strap roll 10 has four bends, and large plastic deformation can be formed at least at the two ends of the strap roll 10.

[0036] In one embodiment, if Figure 7 , when the support plate 4 has a concave structure, the concave structure includes a second guide groove opened on the support plate 4, and the groove walls on both sides of the second guide groove are vertical planes. The width of the pressure head 7 is smaller than the width of the second guide groove. In the support position, the pressure head 7 is located directly above the second guide groove. It can be understood that the smaller the width of the second guide groove, the more conducive it is to the deformation of the strapping roll 10, but it is advisable to avoid the situation where the friction between the strapping roll 10 and the groove wall of the second guide groove is too large, resulting in operational difficulties. The above-mentioned second guide groove preferably also runs through the bottom of the support plate 4, dividing the support plate 4 into two pieces, and the deformed strapping roll 10 can leak out from the bottom end of the second guide groove, so that the strapping roll 10 can be deformed to a greater extent. Figure 7 After the pressure head 7 cooperates with the support plate 4 to bend and deform the strap roll 10, the formed strap roll 10 is roughly U-shaped, and there are 4 bends in the strap roll 10, among which large plastic deformation can be formed at least at the two ends and the middle upper deformation of the strap roll 10.

[0037] Further preferably, in the scheme where the first guide groove / second guide groove divides the support plate 4 into two sub-plates, the opening between the two sub-plates can be further set to be adjustable, that is, the two sub-plates can be moved closer or farther away from each other. For example, one of the sub-plates is connected to a sub-plate driving mechanism, and the sub-plate driving mechanism can adopt a linear driving device such as a hydraulic cylinder or a pneumatic cylinder. Obviously, the driving direction of the sub-plate driving mechanism is parallel to the horizontal direction and perpendicular to the axial direction of the rotating shaft of the rotating fork. By adjusting the opening between the two sub-plates through the sub-plate driving mechanism, on the one hand, it can adapt to the bending operation of strapping rolls of different diameters. On the other hand, when the strapping roll 10 is bent between the two sub-plates, the strapping roll 10 can be further bent by reducing the distance between the two sub-plates, which can effectively improve the plastic deformation effect of the strapping roll 10.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
