[0001] This utility model relates to the field of blade manufacturing technology, and in particular to a steel strip oil spraying device for a blade production line. Background Technology

[0002] Blades, such as thin razor blades, require grinding of a steel strip during their production process. Grinding is typically done using a grinding wheel, and the grinding area needs to be lubricated with oil during the grinding process. In existing technologies, this is usually achieved by installing a nozzle or spray gun above the steel strip, which sprays lubricating oil onto the steel strip. However, the spray range of a single nozzle or spray gun is limited, and the spacing between multiple nozzles or spray guns can lead to uneven oil spraying. Utility Model Content

[0003] The technical problem to be solved by this utility model is: in order to solve the problem that in the prior art, lubricating oil is generally sprayed onto the steel strip by installing a nozzle or spray gun above the steel strip, but the spraying range of a single nozzle or spray gun is limited, and the spacing between multiple nozzles or spray guns will cause uneven oil spraying, a steel strip oil spraying device for a blade production line is provided.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A steel strip oil spraying device for a blade production line includes a blade holder support, a support mechanism located on one side of the blade holder support for supporting the steel strip, and an oil spraying mechanism located on the other side of the blade holder support for spraying oil onto the steel strip.

[0005] The oil injection mechanism includes an injection module and a baffle assembly installed on the side of the injection module near the support mechanism. The injection module has an oil passage extending along its length and multiple oil outlets communicating with the oil passage. The baffle assembly includes an upper baffle and a lower baffle, which together form an oil cavity for receiving oil from the oil outlets and an injection port communicating with the oil cavity for spraying out the oil. The positions of the upper baffle and the lower baffle are adjustable to adjust the injection volume of the injection port.

[0006] The support mechanism includes a blade clamping assembly for holding the steel strip and blade guide assemblies located on both sides of the blade clamping assembly.

[0007] Furthermore, the blade clamp assembly includes a clamping seat mounted on the blade holder bracket, a lower clamping plate adjustablely mounted on the clamping seat, and an upper clamping plate adjustablely mounted on the lower clamping plate. The clamping seat can be adjusted along the steel strip conveying direction, and the upper and lower clamping plates clamp the steel strip, and both can be adjusted in a direction perpendicular to the steel strip conveying direction.

[0008] Furthermore, the blade guide assembly includes a lower guide block fixed on the blade holder bracket, an upper guide block fixed on the lower guide block, and an intermediate guide block located between the two, which together form a guide hole for the steel strip to pass through.

[0009] Furthermore, the injection module includes a main body with the aforementioned oil outlet and mounting portions located at both ends of the main body, and a limiting step is formed between the main body and the mounting portions for limiting the baffle assembly.

[0010] Furthermore, the two ends of the main body protrude towards the support mechanism to form sealing portions for sealing the two ends of the oil cavity.

[0011] Furthermore, the clamping seat includes a base fixed to the tool holder bracket and two support arms extending from the base to the oil spraying mechanism. The support arms constrain and connect the lower clamping plate below it, and a positioning cavity is formed between the two support arms for the upper clamping plate to be inserted and positioned.

[0012] Furthermore, the end of the upper baffle and the lower baffle closest to the support mechanism is its blocking end, and the thickness of the blocking end gradually decreases along the direction closest to the support mechanism.

[0013] The upper and lower clamping plates have their clamping ends near the fuel injection mechanism, and the thickness of the clamping ends gradually decreases along the direction of the fuel injection mechanism.

[0014] Furthermore, the tool holder bracket has protruding limiting parts on both sides for limiting the support mechanism and the oil injection mechanism respectively.

[0015] Furthermore, the oil outlet is a waist-shaped hole.

[0016] The beneficial effects of this utility model are as follows: This utility model uses multiple oil outlets to spray oil into the oil chamber, and the spray nozzles that extend along the steel belt conveying direction and are in the shape of a narrow slit can achieve uniform oil spraying. In addition, the adjustable upper and lower baffles can adjust the spray volume to avoid insufficient lubrication caused by too small a spray volume and waste caused by too large a spray volume. At the same time, the blade clamping assembly provides stable support for the steel belt, which improves the stability of grinding. Attached Figure Description

[0028] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention. Therefore, they only show the components relevant to the present invention. Orientations and references (e.g., up, down, left, right, etc.) are only used to aid in the description of the features in the drawings. Therefore, the following specific embodiments are not intended to be restrictive, and the scope of the claimed subject matter is defined solely by the appended claims and their equivalents.

[0029] like Figure 1 and Figure 2 As shown, a steel strip oil spraying device for a blade production line includes a blade holder support 1, a support mechanism located on one side of the blade holder support 1 for supporting the steel strip, and an oil spraying mechanism 2 located on the other side of the blade holder support 1 for spraying oil onto the steel strip.

[0030] The oil injection mechanism 2 includes an injection module 201 and a baffle assembly installed on the side of the injection module 201 near the support mechanism. The injection module 201 has an oil passage 2011 extending along its length and multiple oil outlets 2012 communicating with the oil passage 2011. The multiple oil outlets 2012 are spaced apart along the length of the oil passage 2011. The oil passage 2011 has a through groove structure, with threaded holes at both ends and sealed with screw plugs to prevent lubricating oil from flowing out. The bottom of the injection module 201 has an oil inlet, and the tool holder bracket 1 has an oil hole communicating with the oil inlet to supply oil to the oil inlet.

[0031] like Figure 3 As shown, the baffle assembly includes an upper baffle 202 and a lower baffle 203, which together form an oil cavity 204 for receiving oil from the oil outlet 2012 and a spray nozzle 205 communicating with the oil cavity 204 and for spraying the oil thereout. The upper baffle 202 and the lower baffle 203 collect the oil into the oil cavity 204 to prevent it from splashing to other locations. The spray nozzle 205 is a narrow slit. The thickness of the spray module 201 gradually decreases along the direction close to the support mechanism. The upper baffle 202 is attached to the upper surface of the spray module 201, and the lower baffle 203 is attached to the lower surface of the spray module 201. The upper baffle 202 and the lower baffle 203 gradually move closer to the support mechanism to form an oil cavity 204 with a triangular cross-section. The positions of the upper baffle 202 and the lower baffle 203 are adjustable to adjust the spray volume of the spray nozzle 205. The upper baffle 202 and the lower baffle 203 are both bolted to the spray module 201, and both the upper baffle 202 and the lower baffle 203 are provided with waist-shaped adjustment holes. When the upper baffle 202 and the lower baffle 203 move away from the support mechanism, they move away from each other and the spray volume increases. When the upper baffle 202 and the lower baffle 203 move closer to the support mechanism, they move closer to each other and the spray volume decreases.

[0032] The support mechanism includes a blade clamping assembly 3 for clamping the steel strip and blade guide assemblies 4 located on both sides of the blade clamping assembly 3. The three are distributed in sequence along the conveying direction of the steel strip. In this embodiment, the blade clamping assembly 3 clamps the steel strip and can provide sufficient support force for the steel strip during grinding with a grinding wheel. However, a small gap is still left between the blade clamping assembly and the clamped steel strip so that the steel strip can be conveyed continuously.

[0033] During grinding, the steel belt enters from one side of the blade guide assembly 4, passes through the blade clamp assembly 3, and exits from the other side of the blade guide assembly 4. The conveying mechanism drives the steel belt to be continuously conveyed. When the steel belt enters the device, lubricating oil enters from the oil hole of the tool holder bracket 1, and enters each oil outlet 2012 in sequence through the oil inlet and oil passage 2011. Then, maintaining a certain oil pressure, the oil flows from the oil outlet 2012 to the oil chamber 204, and is sprayed onto the steel belt below through the spray nozzle 205 to achieve oil spraying lubrication. The spray nozzle 205, which extends along the conveying direction of the steel belt and is in the shape of a narrow slit, can achieve uniform spraying of oil. Furthermore, the adjustable upper baffle 202 and lower baffle 203 can adjust the spray volume to avoid insufficient lubrication due to too small a spray volume and waste due to too large a spray volume.

[0034] In some examples, the blade clamp assembly 3 includes a clamping seat 301 mounted on the blade holder 1, a lower clamping plate 302 adjustablely mounted on the clamping seat 301, and an upper clamping plate 303 adjustablely mounted on the lower clamping plate 302.

[0035] The clamping seat 301 can be adjusted along the steel belt conveying direction. The adjustment structure includes a number of threaded holes spaced apart. When the clamping seat 301 is threadedly connected to the threaded holes at different positions, the clamping seat 301 can be fixed at different positions. The position of the clamping seat 301 corresponds to the grinding position of the grinding wheel so that the steel belt has sufficient stability during the grinding process.

[0036] The upper clamping plate 303 and the lower clamping plate 302 clamp the steel strip, and both can be adjusted in a direction perpendicular to the steel strip conveying direction. Both the upper clamping plate 303 and the lower clamping plate 302 are provided with waist-shaped adjustment holes.

[0037] In some examples, the blade guide assembly 4 includes a lower guide block 401 fixed to the blade holder 1, an upper guide block 402 fixed to the lower guide block 401, and an intermediate guide block 403 located between the two, which together form a guide hole 404 for the steel strip to pass through.

[0038] In some examples, the injection module 201 includes a main body 2013 with the aforementioned oil outlet 2012 and mounting portions 2014 located at both ends of the main body 2013. A limiting step 2015 for limiting the baffle assembly is formed between the main body 2013 and the mounting portion 2014. First, the limiting steps 2015 on both sides limit the baffle assembly between them for initial positioning. Then, the baffle assembly is fixed to the injection module 201 by bolts.

[0039] In some examples, the two ends of the main body 2013 protrude toward the support mechanism to form a sealing part 2016 for sealing the two ends of the oil cavity 204, and the thickness of the sealing part 2016 gradually decreases from the direction closer to the support mechanism.

[0040] In some examples, the clamping seat 301 includes a base 3011 fixed to the tool holder 1 and two support arms 3012 extending from the base 3011 toward the oil injection mechanism 2. The support arms 3012 define and connect the lower clamping plate 302 below it, and a positioning cavity 3013 is formed between the two support arms 3012 for the upper clamping plate 303 to be inserted and positioned. The lower surface of the support arm 3012 abuts against the lower clamping plate 302 to define the longitudinal position of the lower clamping plate 302 and the upper clamping plate 303. The positioning cavity 3013 can define the lateral position of the upper clamping plate 303 and the lower clamping plate 302.

[0041] In some examples, the upper baffle 202 and the lower baffle 203 have a blocking end 206 at the end near the support mechanism, and the thickness of the blocking end 206 gradually decreases in the direction near the support mechanism.

[0042] The upper clamping plate 303 and the lower clamping plate 302 have their clamping ends 304 near the oil injection mechanism 2, and the thickness of the clamping end 304 gradually decreases along the direction near the oil injection mechanism 2, thereby improving the clamping effect.

[0043] In some examples, the tool holder 1 has protruding limiting parts 101 on both sides for limiting the support mechanism and the oil injection mechanism 2, respectively.

[0044] In some examples, the oil outlet 2012 is an oblong hole, which has a large cross-sectional area and can obtain a large oil output.

[0045] Working principle:

[0046] During grinding, the steel belt enters from one side of the blade guide assembly 4, passes through the blade clamp assembly 3, and exits from the other side of the blade guide assembly 4. The conveying mechanism drives the steel belt to be continuously conveyed. When the steel belt enters the device, lubricating oil enters from the oil hole of the tool holder bracket 1, and enters each oil outlet 2012 in sequence through the oil inlet and oil passage 2011. Then, maintaining a certain oil pressure, the oil flows from the oil outlet 2012 to the oil chamber 204, and is sprayed onto the steel belt below through the spray nozzle 205 to achieve oil spraying lubrication. The spray nozzle 205, which extends along the conveying direction of the steel belt and is in the shape of a narrow slit, can achieve uniform spraying of oil. Furthermore, the adjustable upper baffle 202 and lower baffle 203 can adjust the spray volume to avoid insufficient lubrication due to too small a spray volume and waste due to too large a spray volume.

The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
