Description

Technical Field

[0001] The utility model belongs to the technical field of flat steel packaging, and in particular relates to a flat steel packaging head pressing machine. Background Art

[0002] After the flat steel is stacked, the cross section presents a square bag structure. After being bundled by the square bag automatic baler, the direction of the twisted head is inclined upward. Since the finished materials must be stacked after storage, the twisted head of each bundle of flat steel will cause scratches or crushing to the bottom surface of the upper layer of flat steel bundles, which directly affects the surface quality of the product. On site, the twisted head is usually bent by manual knocking so that it no longer interferes with the flat steel bundle above. However, the manual knocking method is inefficient and labor-intensive. Therefore, a flat steel bundle head pressing machine is proposed. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1 As shown, a flat steel bundle pressing machine is used to flatten the kinked head 31 on the flat steel bundle 3 so that it will not interfere with the flat steel bundle at the upper end when stacking;

[0025] The flat steel bundle pressing machine comprises a mounting frame 1, on which a slidable support plate 2 is arranged. Figure 3 As shown, two support rods 21 are arranged at the upper end of the support plate 2, and the flat steel bundle 3 is placed on the support rods 21, and the ropes on the flat steel bundle 3 are not in contact with the support plate 2; a clamping assembly 4 is arranged on the support plate 2, and the clamping assembly 4 is used to center and fix the flat steel bundle 3, and a pressing plate assembly 5 is also arranged at the upper end of the mounting frame 1, and the support plate 2 is controlled to move and drive the flat steel bundle 3 to move to the pressing plate assembly 5, and under the action of the pressing plate assembly 5, the kinked head 31 on the flat steel bundle 3 can be flattened;

[0026] It is worth mentioning that after the flat steel bundle 3 is clamped in the center, it is ensured that the relative position between the flat steel bundle 3 and the support plate 2 in the moving direction of the support plate remains consistent after each clamping of the flat steel bundle 3, so that when the same type of flat steel bundle is flattened by the twisting head 31, it is not necessary to adjust the moving parameters of the support plate 2 each time the flat steel bundle 3 is replaced, and the flat steel bundle 3 can be moved to the same position, which is convenient for the pressing plate assembly 5 to correspond to the twisting head 31, so as to deform and perform batch flattening operations;

[0027] like Figure 4 As shown, the clamping assembly 4 includes two clamping plates 41 that can slide synchronously in opposite directions. The two clamping plates 41 are close to each other and can center and clamp the flat steel bundle 3;

[0028] In this embodiment, the two clamping plates 41 are slidably connected to the clamping plates 41, and the sliding direction is parallel to the moving direction of the support plate 2. Two first fixing plates 23 are arranged at the lower end of the support plate 2. A first screw rod 42 is rotatably connected between the two first fixing plates 23. The two ends of the first screw rod 42 are respectively provided with a first external thread 421 and a second external thread 422 with opposite rotation directions and equal pitches. The first external thread 421 and the second external thread 422 respectively penetrate the two clamping plates 41 and are threadedly connected to the clamping plates 41. By arranging a motor on one of the first fixing plates 23 to drive the first screw rod 42 to rotate, the two clamping plates 41 can be synchronously slid in the opposite directions.

[0029] Furthermore, in order to ensure the stability of clamping the flat steel bundle 3, the first screw rod 42 needs to have a self-locking capability, and the thread lead angles of the first external thread 421 and the second external thread 422 are both smaller than the equivalent friction angle.

[0030] Of course, the method of driving the two clamping plates 41 to slide synchronously in opposite directions includes but is not limited to the first screw rod 42 and other structures in this embodiment. In some embodiments, two cylinders can be set on the support plate 2 to drive the two clamping plates 41 to slide synchronously in opposite directions respectively.

[0031] In addition, in this embodiment, a mounting groove is opened on the support rod 21, and a plurality of rollers 22 are rotatably connected in the mounting groove, so that the flat steel bundle 3 and the rollers 22 are in rolling contact in the sliding direction of the clamping plate 41. When the clamping plate 41 is in contact with the flat steel bundle 3, it can drive the flat steel bundle 3 to move toward the middle position. At this time, due to the rolling contact between the flat steel bundle 3 and the rollers 22, the friction damage received by the lower end of the flat steel bundle 3 is reduced.

[0032] like Figure 5 As shown, the pressing plate assembly 5 includes a fixing frame 51 fixed to the upper end of the mounting frame 1, and a pressing plate 53 capable of being raised and lowered is arranged on the fixing frame 51. The pressing plate 53 is lowered to act on the kinking head 31 until the pressing plate 53 contacts the upper end surface of the flat steel bundle 3, and the kinking head 31 is flattened;

[0033] In this embodiment, a hydraulic cylinder 52 is arranged on the fixed frame 51, and the end of the driving shaft of the hydraulic cylinder 52 is fixed to the pressure plate 53. Driven by the hydraulic cylinder 52, the pressure plate 53 can be raised and lowered and act on the kinking head 31; of course, in some embodiments, the hydraulic cylinder 52 can be replaced by providing linear driving components such as cylinders and telescopic rods to drive the pressure plate 53 to rise and fall.

[0034] In this embodiment, the support plate 2 is slidably connected to the mounting frame 1. Figure 2As shown, two second fixing plates 11 are provided on the mounting frame 1, and a second screw rod 6 is rotatably connected between the two second fixing plates 11. A third fixing plate 24 is provided at the lower end of the support plate 2, and the second screw rod 6 penetrates the third fixing plate 24 and is threadedly connected thereto. By arranging a motor on one of the second fixing plates 11 to drive the second screw rod 6 to rotate, the support plate 2 can be driven to slide;

[0035] Furthermore, in order to ensure that the support plate 2 remains stable after sliding to a specified position, the second screw rod 6 needs to have a self-locking property, that is, the thread lead angle of the second screw rod 6 is smaller than the equivalent friction angle.

[0036] Of course, the method of driving the support plate 2 to slide on the mounting frame 1 includes but is not limited to the second screw rod 6 and other structures in this embodiment. In some embodiments, the support plate 2 can also be directly driven to slide by arranging hydraulic cylinders, telescopic rods and other linear driving components on the mounting frame 1.

[0037] In addition, it is worth mentioning that a clearance hole is provided on the third fixing plate 24 to facilitate the clearance of the first screw rod 42 .

[0038] Working principle:

[0039] By arranging a slidable support plate 2 on the mounting frame 1, the flat steel bundle 3 is placed on two support rods 21 at the upper end of the support plate 2, and a clamping plate assembly 4 is arranged on the support plate 2, and two clamping plates 41 that can slide synchronously in opposite directions are arranged in the clamping plate assembly 4 to achieve the centering clamping of the flat steel bundle 3, so that each time the flat steel bundle 3 is clamped, it is not necessary to adjust the movement parameters of the support plate 2, and it can be ensured that each flat steel bundle 3 can reach the pressure plate assembly 5, and the kink head 31 is flattened under the action of the pressure plate assembly 5, so that the kink head will not interfere with the flat steel bundle at the upper end during stacking. Rolling contact with the flat steel bundle 3 is achieved by arranging a roller 22 on the support rod 21. When the clamping plate 41 drives the flat steel bundle 3 to move toward the middle position, the friction damage received by the lower end of the flat steel bundle 3 is reduced due to the rolling contact between the flat steel bundle 3 and the roller 22.
