Description

Technical Field

[0001] The utility model relates to the technical field of tension rollers, in particular to a tension roller for hand-tearable steel. Background Technique

[0002] Hand-tearable steel, scientifically named stainless steel foil, is a kind of precision stainless steel strip with extremely small thickness. Although the thickness is extremely thin, the hardness and stiffness of hand-tearable steel remain unchanged. At the same time, it has the advantages of light weight, high strength, strong toughness, good corrosion resistance and oxidation resistance, etc., and can maintain stable performance in a variety of harsh environments, and is widely used in fields such as aerospace and electronics.

[0003] During the processing or use of hand-tearable steel, in order to prevent the hand-tearable steel from loosening or deforming and affecting its dimensional accuracy and performance, it is usually necessary to use a tension roller to tension the hand-tearable steel. However, at present, the tension provided by the tension roller used for tensioning the hand-tearable steel is usually a fixed value, and the tensioning degree is not easy to adjust, and it is difficult to meet the tensioning requirements of hand-tearable steel with different performances. Therefore, this application proposes a tension roller for hand-tearable steel. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a tension roller for hand-tearable steel, which has the advantages of good elastic lifting effect and adjustable tensioning force for hand-tearable steel, strong applicability and high flexibility.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A tension roller for hand-tearable steel, comprising a base and a tension roller body for guiding and feeding hand-tearable steel. An installation frame is provided on the tension roller body. A pair of support arms are hinged to the bottom of the installation frame of the tension roller body. A pair of sliders and a pair of stoppers are slidably arranged on the top of the base. The pair of sliders and the pair of stoppers are distributed along the same length direction. The pair of sliders are located between the pair of stoppers. The bottom ends of the pair of support arms are respectively hinged to the pair of sliders. Elastic springs for elastically supporting the pair of sliders are arranged on the opposite sides of the pair of stoppers. An adjusting mechanism for driving the pair of stoppers to approach or separate from each other is arranged on the base.

[0007] Preferably, a guide groove is opened on the base. The pair of sliders and the pair of stoppers are both slidably installed in the guide groove. Convex blocks that are slidably fitted to the upper surface of the base are arranged on both sides of the top of the slider.

[0008] Preferably, the guide groove vertically penetrates the base. The adjusting mechanism includes mounting blocks fixed at both ends of the bottom of the base, a bidirectional lead screw rotatably installed between the pair of mounting blocks, and a motor installed on one of the mounting blocks for driving the bidirectional lead screw to rotate. The bottom ends of the pair of stoppers are symmetrically threadedly sleeved on the bidirectional lead screw.

[0009] Preferably, a connecting plate is jointly hinged at the top ends of a pair of the support arms, and the mounting frame of the tension roller body is fixed on the connecting plate.

[0010] Preferably, a guide post is vertically fixed at the bottom of the connecting plate, a sleeve post is movably sleeved at the bottom end of the guide post, and the sleeve post is vertically fixed on the base.

[0011] Preferably, mounting plates are vertically arranged on both sides of the bottom of the base, ear plates are arranged at the bottoms of the mounting plates, and mounting holes are formed in the ear plates.

[0012] Preferably, a slide bar is horizontally fixed in the guide groove, the slide bar movably penetrates through the slider and the stop block, and the spring is sleeved on the slide bar.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] Through the arrangement of the springs, sliders and support arms, under the elastic force of a pair of springs, a pair of sliders are urged to slide along the guide grooves to push the bottom ends of a pair of support arms closer together. At this time, the tension roller body is elastically lifted, which can be used for elastic tensioning of the hand-torn steel. Since two horizontally distributed springs are used in cooperation with a pair of sliders and a pair of support arms to achieve elastic lifting of the tension roller body, compared with a single spring vertically elastically lifting the tension roller body, it has a good elastic lifting effect, improves the elastic tensioning effect on the hand-torn steel, and at the same time shortens the assembly height and is more applicable.

[0015] Through the arrangement of the adjusting mechanism, when the motor is started to drive the bidirectional lead screw to rotate, a pair of stop blocks are driven to move closer to or away from each other, and the distance between the pair of stop blocks can be adjusted. On the premise that the springs cooperate with a pair of sliders and support arms to elastically lift the tension roller body to achieve tensioning of the hand-torn steel, the tensioning force on the hand-torn steel can be adjusted to meet different tensioning requirements of the hand-torn steel, and it has the advantages of being adjustable and highly flexible.

[0023] Embodiment

[0024] Please refer to Figures 1 to 4 , the present utility model preferably provides the following technical solution:

[0025] A tension roller for hand-torn steel includes a base 1 and a tension roller body 2 for guiding and feeding hand-torn steel. There is a mounting frame on the tension roller body 2. A pair of support arms 3 are hinged to the bottom of the mounting frame of the tension roller body 2. A pair of sliders 4 and a pair of stop blocks 5 are slidably arranged on the top of the base 1. The pair of sliders 4 and the pair of stop blocks 5 are distributed along the same length direction. The pair of sliders 4 are located between the pair of stop blocks 5. The bottom ends of the pair of support arms 3 are respectively hinged to the pair of sliders 4. A spring 6 for elastically supporting the pair of sliders 4 is arranged on the opposite sides of the pair of stop blocks 5 facing each other. An adjustment mechanism 7 for driving the pair of stop blocks 5 to approach or separate from each other is arranged on the base 1. In this embodiment, a guide groove 8 is opened on the base 1. The pair of sliders 4 and the pair of stop blocks 5 are both slidably installed in the guide groove 8. Through the above structural method, under the elastic force of the pair of springs 6, the pair of sliders 4 are urged to slide along the guide groove 8 to push the bottom ends of the pair of support arms 3 to approach each other. At this time, the tension roller body 2 is elastically lifted, and can be used for elastic tensioning of hand-torn steel. Since the elastic lifting of the tension roller body 2 is realized by the cooperation of two horizontally distributed springs 6 with a pair of sliders 4 and a pair of support arms 3, compared with the elastic lifting of the tension roller body 2 by a single spring 6 vertically, it has a good elastic lifting effect, improves the elastic tensioning effect on hand-torn steel, and at the same time shortens the assembly height, has high applicability. In addition, by using the adjustment mechanism 7 to drive the pair of stop blocks 5 to approach or separate from each other, the distance between the pair of stop blocks 5 can be adjusted. On the premise that the spring 6 cooperates with the pair of sliders 4 and the support arms 3 to elastically lift the tension roller body 2 to realize the tensioning of hand-torn steel, the tensioning force on hand-torn steel can be adjusted to meet different tensioning requirements of hand-torn steel.

[0026] In this embodiment, bumps 19 that are slidably fitted to the upper surface of the base 1 are provided on both sides of the top of the slider 4 to ensure the smooth sliding of the slider 4.

[0027] Furthermore, in this embodiment, the guide groove 8 vertically penetrates the base 1. The adjusting mechanism 7 includes mounting blocks 16 fixed to both ends of the bottom of the base 1, a bidirectional lead screw 17 rotatably mounted between a pair of mounting blocks 16, and a motor 18 mounted on one of the mounting blocks 16 for driving the rotation of the bidirectional lead screw 17. The bottom ends of a pair of stoppers 5 are symmetrically threadedly sleeved on the bidirectional lead screw 17. By starting the motor 18 to drive the rotation of the bidirectional lead screw 17, a pair of stoppers 5 can be driven to approach or move away from each other, thereby adjusting the tension force on the hand-torn steel.

[0028] In a further embodiment, a connecting plate 15 is jointly hinged to the tops of a pair of support arms 3. The mounting frame of the tension roller body 2 is fixed to the connecting plate 15. A guide post 14 is vertically fixed to the bottom of the connecting plate 15. The bottom end of the guide post 14 is movably sleeved with a sleeve post 13, and the sleeve post 13 is vertically fixed to the base 1. By using the socketing cooperation between the sleeve post 13 and the guide post 14, the lifting movement of the tension roller body 2 can be limited and guided.

[0029] In this embodiment, mounting plates 10 are vertically provided on both sides of the bottom of the base 1. An ear plate 11 is provided at the bottom of the mounting plate 10, and a mounting hole 12 is provided in the ear plate 11 for the assembly of the tension roller. A slide bar 9 is horizontally fixed in the guide groove 8. The slide bar 9 movably penetrates the slider 4 and the stopper 5. A spring 6 is sleeved on the slide bar 9. The slide bar 9 can achieve the limiting and guiding of the slider 4 and the stopper 5, and at the same time, the slide bar 9 can prevent the spring 6 from being bent.

[0030] During use, the base 1 is installed and fixed on the conveying line of the hand-torn steel by bolts in cooperation with the mounting plate 10, the ear plate 11, and the mounting hole 12. Under the elastic push of a pair of springs 6, a pair of sliders 4 are urged to slide along the guide groove 8 to push the bottom ends of a pair of support arms 3 closer. At this time, the tension roller body 2 is elastically lifted, and it can be used for elastic tensioning of the hand-torn steel. Since two horizontally distributed springs 6 are used in cooperation with a pair of sliders 4 and a pair of support arms 3 to achieve the elastic lifting of the tension roller body 2, compared with a single spring 6 vertically elastically lifting the tension roller body 2, it has a good elastic lifting effect, improves the elastic tensioning effect on the hand-torn steel, and at the same time shortens the assembly height, making it more applicable. Furthermore, by starting the motor 18 to drive the rotation of the bidirectional lead screw 17, a pair of stoppers 5 are driven to approach or move away from each other, and the distance between a pair of stoppers 5 can be adjusted. On the premise that the spring 6 is used in cooperation with a pair of sliders 4 and the support arms 3 to elastically lift the tension roller body 2 to achieve the tensioning of the hand-torn steel, the tension force on the hand-torn steel can be adjusted to meet different tensioning requirements of the hand-torn steel, and it has the advantages of being adjustable and highly flexible.
