Description

Technical Field

[0001] The utility model relates to the technical field of gantry shearing machines, in particular to a strip material feeding device for shearing machines. Background Art

[0002] Gantry shear is a scrap metal shearing equipment that can shear all kinds of scrap metal (such as metal strips). When the gantry shear is working, the scissor seat and the shearing platform shear against each other up and down to complete the shearing of strip materials. However, there are the following problems in the specific shearing process:

[0003] One is that during the cutting process of strip materials, due to the large pressure difference at both ends, the uncut end may be suspended in the air or even tilted. This situation is not only dangerous (such as the material flying after cutting), but also if the material to be cut is multiple strip materials, the material that was originally relatively neat after a single cut will appear messy after cutting. If there are specific requirements for the cutting length, the strip materials must be re-arranged before subsequent cutting.

[0004] In view of this, there is an urgent need for a strip material feeding device for a shearing machine that can solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a strip material feeding device for a shearing machine which solves the above problems.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solution: a strip material feeding device for a shearing machine, comprising:

The feed box is detachably connected to the feed end of the shearing machine, a feed port is provided on its side wall, and a discharge port is provided at the end close to the shearing machine. The pushing mechanism is fixedly connected to the end of the feed box away from the shearing machine, multiple material pressing components are movably connected to the top wall of the feed box close to the shearing machine, and the conveyor belt is detachably connected to the feed port.

[0008] Preferably, the pushing mechanism includes a pushing cylinder, a pushing block and a folding baffle plate. The pushing cylinder is fixedly connected to the side wall of the feed box away from the shearing machine. The pushing block is located in the feed box and is fixedly connected to the piston rod of the pushing cylinder. One end of the folding baffle plate is fixedly connected to the side wall of the feed box away from the shearing machine, and the other end is fixedly connected to the pushing block.

[0010] Preferably, the conveyor belt is provided with a bell mouth for guiding the strip-shaped materials.

[0011] Preferably, the feed port is located at the upper end of the side wall of the feed box, and its height is less than 1 / 2 of the height of the feed box.

[0012] Preferably, the feed box is provided with a maximum shear thickness adjustment assembly, which includes an adjustment plate and an adjustment handle. The adjustment plate is located in the feed box near one end of the shearing machine.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Embodiment 1

[0025] Please refer to the attached Figure 1-3 , a strip material feeding device for a shearing machine, comprising:

[0026] A conveyor belt 1, a feed box 2, a pushing mechanism 3 and a plurality of material pressing assemblies 4, wherein the feed box 2 is detachably connected to the feed end of the shearing machine, a feed port 20 is provided on its side wall, and a discharge port 21 is provided at an end close to the shearing machine, the pushing mechanism 3 is fixedly connected to the end of the feed box 2 away from the shearing machine, a plurality of the material pressing assemblies 4 are movably connected to the top wall of the feed box 2 close to the shearing machine, and the conveyor belt 1 is detachably connected to the feed port 20.

[0027] During specific use, the strip material can be conveyed from the feed port 20 to the feed box 2 through the conveyor belt 1. After it is accumulated to a certain extent, the pushing cylinder 30 is started, and the piston rod drives the pushing block 31 to push the strip material in the feed box 2 to the feed end of the shearing machine for shearing. During this process, the strip material will contact the baffle 42 and drive the baffle 42 to rotate. During the rotation of the baffle 42, it will contact the sleeve rod 40 and complete the squeezing of the pressure spring 41 in the sleeve rod 40. In this way, the purpose of fixing the strip material is achieved by utilizing the reaction force of the spring 41, thereby avoiding the situation where the strip material is lifted away from one end of the shearing machine during the cutting process of the shearing machine.

[0028] Specifically, the pushing mechanism 3 includes a pushing cylinder 30, a pushing block 31 and a folding baffle plate 32. The pushing cylinder 30 is fixedly connected to the side wall of the feeding box 2 away from the shearing machine. The pushing block 31 is located in the feeding box 2, and is fixedly connected to the piston rod of the pushing cylinder 30. One end of the folding baffle plate 32 is fixedly connected to the side wall of the feeding box 2 away from the shearing machine, and the other end is fixedly connected to the pushing block 31; the pushing block 31 and the folding baffle plate 32 on the side wall of the feeding box 2 away from the shearing machine are gradually unfolded during the movement of the pushing block 31. Based on the above design, there is no need to shut down the conveyor belt 1 during the pushing process. During the pushing process, the second batch of strip materials close to the shearing machine will fall on the strip materials in motion on the lower layer of the feeding box, and the end away from the shearing machine will fall on the unfolded folding baffle plate 32, and the folding baffle plate 32 will continue to move. The second batch of strip materials will all fall on the fully unfolded folding baffle plate 32 during the pushing process. After the pushing cylinder 30 completes a single pushing, as the piston rod retracts the pushing cylinder 30, the strip materials on the folding baffle plate 32 can fall again on the lower layer of the feeding box 2, waiting for the next start of the pushing cylinder 30. The above method greatly reduces the waiting time of the filling process when the pushing cylinder 30 is started again. Even when the conveying rate of the conveyor belt 1 matches the pushing cylinder 30, the uninterrupted operation of the pushing cylinder 30 can be achieved, and the waiting stage for the second filling can be directly achieved. It is worth noting that the plate material of the folding baffle plate 32 needs to have a certain hardness, and its folding method is similar to that of the folding door. At the same time, considering that the space in the feeding box 2 is artificially set as the concept of upper and lower layers, two sets of barrier plates 6 can be set up inside the feeding box 2, and their positions are as shown in the attached figure. Figure 2 As shown, it is avoided that the upper material moves toward the shearing machine due to the friction of the lower material during the pushing process, or the upper material moves toward the pushing cylinder 30 due to the friction of the pushing block 31 or the folding baffle plate 32.

[0029] Specifically, the material clamping assembly 4 includes a sleeve rod 40, a pressure spring 41 and a baffle 42, the baffle 42 being elastically hinged to the top wall of the feed box 2 at one end away from the shearing machine, one end of the sleeve rod 40 being fixedly connected to the inner top wall of the feed box 2, and the other end being in contact with the end of the baffle 42 close to the shearing machine, and the pressure spring 41 being fixedly connected to the inner side of the sleeve rod 40; the pressure spring 41 arranged in the sleeve rod 40 is forced to generate a reaction force to squeeze the moving material downward to achieve the purpose of clamping the strip material, thereby avoiding the situation where the strip material is tilted away from the end of the shearing machine during the shearing process. It is worth noting that in order to avoid the situation where the baffle 42 is subjected to a vertical downward component of force due to the contact angle between the strip material and the baffle 42, thereby causing the baffle 42 to be locked and unable to rotate, the contact surface between the baffle 42 and the strip material can avoid the above situation by adopting a curved surface.

[0030] Specifically, the conveyor belt 1 is provided with a bell mouth 10 for guiding the strip materials; considering that arranging the strip materials and then placing them on the conveyor belt 1 will increase the workload of the staff, the bell mouth 10 is added to preliminarily guide the strip materials to make them tend to a more orderly state.

[0031] Specifically, the feed port 20 is located at the upper end of the side wall of the feeding box 2, and its height is less than 1 / 2 of the height of the feeding box 2; the height limit of the feed port 20 is to limit the strip materials in the upper and lower layers of the feeding box 2 to avoid excessive accumulation of strip materials in the upper layer of the feeding box 2.

[0032] Embodiment 2

[0033] Please refer to the attached Figure 4

[0034] Specifically, the feed box 2 is provided with a maximum shear thickness adjustment component 5, which includes an adjustment plate 50 and an adjustment handle 51. The adjustment plate 50 is located in the feed box 2 near one end of the shearing machine, and one end of the adjustment handle 51 penetrates the top wall of the feed box 2 and is movably connected to the middle position of the adjustment plate 50, and the adjustment handle 51 is threadedly connected to the top wall of the feed box 2; in actual applications, there are situations where the single cutting amount of the strip material is different due to the different materials of the strip material or the models of the shearing machine. The setting of the maximum shear thickness adjustment component 5 can change the position of the adjustment plate 50 through the adjustment handle 51, and after the maximum shear thickness adjustment component 5 is added, the material clamping component 4 needs to change its position from the top of the feed box 2 to be movably connected to the adjustment plate 50, so as to achieve the purpose of adjusting the variable position of the material clamping component 4, and then achieve the purpose of adjusting the single maximum shear thickness of the strip material through the adjustment handle 51.

[0035] Embodiment 3

[0036] Please refer to the attached Figure 5

[0037] The feed box 2 is provided with a maximum shear thickness adjustment component 5, which includes an adjustment plate 50 and at least two adjustment handles 51. The adjustment plate 50 is located in the feed box 2 near one end of the shearing machine, and one end of a plurality of adjustment handles 51 penetrates the top wall of the feed box 2 and is respectively movably connected to the adjustment plate 50, and the adjustment handles 51 are threadedly connected to the top wall of the feed box 2; considering that in actual applications, the distance between the strip material and the shearing machine may be different and there may be a need to apply different pressures through the baffle 42, the single adjustment handle 51 is changed to a double adjustment handle 52, and the inclination of the adjustment plate 50 is changed by means of different lengths of the actual application parts of the double adjustment handles 52 in the feed box 2, thereby achieving the purpose of applying different pressures at different positions of multiple material clamping components 4.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
