Description

Technical Field

[0001] This utility model relates to the field of cold rolling feeding technology, specifically a cold rolling feeding machine for aluminum sheet and strip production. Background Technology

[0002] Aluminum sheets are widely used in industries such as aviation, aerospace, construction, printing, transportation, electronics, chemicals, food, and medicine. During the rolling process, aluminum sheets generate a large amount of deformation heat and frictional heat due to their high coefficient of friction and high pressing force. Therefore, rolling oil is needed to cool and lubricate the work rolls and aluminum sheet strips during the rolling process. As a result, a lot of cold rolling oil adheres to the aluminum sheet strips. This cold rolling oil will affect the subsequent processing of the aluminum sheet. The existing surface treatment method for cold rolling aluminum sheet strips is generally to remove the cold rolling oil by passing the aluminum sheet through a vertical scraper via a conveyor belt.

[0003] Publication No. CN222306888U discloses a surface treatment device for cold rolling aluminum sheet and strip, including a housing and a feeding mechanism. The housing has two electric push rods, one and two, respectively, located in the middle of its top wall. The first electric push rod is positioned at the front end of the second electric push rod. A cleaning mechanism is located below the telescopic end of the first electric push rod, and a cleaning mechanism is located below the telescopic end of the second electric push rod. A support plate is located between the left and right walls of the housing, and a scraper is located in the middle of the upper side of the support plate. The feeding mechanism is located between the left and right walls of the housing. The device also includes a microcontroller. This surface treatment device for cold rolling aluminum sheet and strip can adjust the scraper angle according to the thickness of the aluminum sheet when scraping off the cold rolling oil. The scraper effectively removes the cold rolling oil from the aluminum sheet and can promptly clean the accumulated cold rolling oil in front of the scraper, providing a good working environment for subsequent surface treatment of the aluminum sheet and strip. However, this patent still has the following problems in actual use:

[0004] Traditional feeders use a single roller conveyor, which results in insufficient positioning accuracy of the sheet metal, leading to deviation during cold rolling and affecting product quality. The aforementioned devices lack effective multi-directional positioning and clamping functions, and the sheet metal will still vibrate and shift during conveying. Moreover, the aforementioned devices achieve scraping by reciprocating scraper movement. At this time, the scraper must remain stationary; otherwise, the scraping trajectory will be wavy, with gaps and omissions, affecting scraping efficiency.

[0005] A cold rolling feeder for aluminum sheet and strip production is proposed to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a cold rolling feeder for aluminum sheet and strip production, in order to solve the problems mentioned in the background art. Traditional feeders use a single roller conveyor, which has insufficient plate positioning accuracy, leading to deviation during cold rolling and affecting product quality. Although the above-mentioned device adds a lateral positioning mechanism, it lacks a vertical clamping function, and the plate will still vibrate and shift during conveying. Moreover, the above-mentioned device achieves scraping by reciprocating movement of a scraper. At this time, the scraper must remain stationary, otherwise the scraping trajectory will be wavy, with gaps and omissions, affecting scraping efficiency.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a cold rolling feeder for aluminum sheet and strip production, comprising an electric roller conveyor, wherein the electric roller conveyor comprises a housing, and two sets of electric rollers are arranged horizontally and parallel to each other at the lower part of the housing, with a gap between the two sets of electric rollers;

[0008] A positioning assembly is provided in the middle of the interior of the housing. The positioning assembly includes two pairs of arch frames symmetrically and slidably installed inside the electric roller conveyor. An electric push rod is fixedly connected to the middle of the arch frame. A clearance groove is symmetrically opened on both sides of the arch frame. A moving plate is slidably connected inside the clearance groove. A side pressure wheel is rotatably connected to one side of the moving plate. A U-shaped rod is fixedly connected to the other side of the moving plate. A linkage column is rotatably connected to the end of the U-shaped rod away from the clearance groove. A U-shaped cover is symmetrically provided above the arch frame. Inclined grooves are symmetrically opened on both sides of the U-shaped cover. Connecting blocks are fixedly connected to the bottom of both sides of the U-shaped cover. A support column is slidably connected to the middle of the connecting block. A first spring is sleeved on the outside of the support column. A fixing pad is fixedly connected to the bottom of the support column.

[0009] Among them, an upper pressure roller is fixedly installed on the outside of one side of the U-shaped cover, and the upper pressure roller is located above the side pressure roller;

[0010] A scraping assembly is provided between the two pairs of electric rollers.

[0011] Preferably, the electric push rod is fixedly connected to the housing, and a ball is rotatably connected to the bottom of the arch frame, the ball being in contact with the outer surface of the electric roller.

[0012] Preferably, the top end of the first spring is fixedly connected to the connecting block, the bottom end of the first spring is fixedly connected to the fixing pad, and the fixing pad is fixedly connected to the top surface of the arch frame.

[0013] Preferably, the linkage column is slidably connected to the inclined groove.

[0014] Preferably, the scraping assembly includes a suspension rod disposed between two arches on the same side, a plurality of crossbars slidably connecting the two suspension rods, mounting pads and second springs being sleeved at both ends of each crossbar, a docking hole being provided in the middle of each crossbar, the docking hole being a rectangular hole, a docking post being connected through the docking hole, a scraper being fixedly connected to the bottom end of the docking post, a stud being fixedly connected to the top end of the docking post, the scraper being located above the gap between the two sets of electric rollers, and the scraper being inclined.

[0015] Preferably, the mounting pad is fixedly connected to the crossbar, one end of the second spring is fixedly connected to the mounting pad, and the other end of the second spring is fixedly connected to the crossbar.

[0016] Preferably, the diameter of the stud is not greater than the width of the mating post, and the stud is threadedly connected to the nut.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: This cold rolling feeder for aluminum sheet and strip production drives the arch frame and moving plate together through an electric push rod, and with the combined transmission of the inclined groove and the connecting column, it achieves one-time precise positioning of the sheet in the lateral and vertical directions, ensuring that the sheet remains stable and centered during the conveying process, avoiding vibration and scratches that cause the sheet to tilt and affect subsequent processing. The specific details are as follows:

[0018] 1. First, the combined structure of the arch frame and moving plate driven by electric actuators, through the sliding constraint of the avoidance groove, allows the side pressure roller to automatically convert into vertical pressing motion after contacting the plate, achieving bidirectional positioning driven by a single power source, which improves efficiency compared to the traditional step-by-step positioning method. Second, the unique inclined groove-linking column mechanism precisely converts horizontal movement into the vertical pressing action of the upper pressure roller, and with the buffer design of the first spring, it can adaptively adjust to plates of various thicknesses. Moreover, the linkage structure of the U-shaped cover and the support column ensures that lateral positioning and vertical pressing are completed simultaneously, reducing the cost of equipment components.

[0019] 2. Through a composite design combining elastic suspension and mechanical linkage, the oil scraping operation achieves adaptive adjustment and efficient execution. Firstly, the rigid connection between the suspension rod and the U-shaped cover ensures that the scraper bar rises and falls synchronously with the clamping mechanism, maintaining the optimal working gap between the scraper bar and the sheet surface, reducing oil film residue compared to fixed oil scraping devices. Secondly, the symmetrically arranged second spring structures on both sides of the crossbar, combined with the directional guidance design of the docking holes, ensure the scraper bar's tracking ability on the sheet. Furthermore, the modular scraper bar installation method allows for quick replacement of the scraper bar through the rapid disassembly and assembly of studs and nuts, and the inclined scraper bar guides the scraped oil, significantly improving the quality of cold rolling pretreatment.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-6 This utility model provides a technical solution: a cold rolling feeder for aluminum sheet and strip production, including an electric roller conveyor 1. The electric roller conveyor 1 includes a housing 101. Inside the housing 101, two sets of electric rollers 102 are arranged horizontally and parallel to each other, with a gap between the two sets of electric rollers 102. This structural design ensures stable sheet conveying, and the gap area facilitates subsequent oil scraping operations. Scrapers can also be fixedly installed in the gap area. The top of the scraper is parallel to the upper surface of the electric roller 102, and oil can also be scraped from the lower surface of the sheet.

[0029] A positioning component 2 is provided in the middle of the housing 101. The positioning component 2 includes two pairs of arch frames 201 that are symmetrically and slidably installed inside the electric roller conveyor 1. An electric push rod 202 is fixedly connected to the middle of the arch frame 201. A clearance groove 203 is symmetrically opened on both sides of the arch frame 201. A moving plate 204 is slidably connected inside the clearance groove 203. During operation, the electric push rod 202 drives the arch frame 201 to move, and the moving plate 204 is guided by the clearance groove 203 to achieve precise positioning.

[0030] A side pressure wheel 205 is rotatably connected to one side of the movable plate 204, and a U-shaped rod 206 is fixedly connected to the other side of the movable plate 204. A linkage column 207 is rotatably connected to the end of the U-shaped rod 206 away from the clearance groove 203.

[0031] A U-shaped cover 208 is symmetrically provided above the arch frame 201. Inclined grooves 209 are symmetrically provided on both sides of the U-shaped cover 208. Connecting blocks 210 are fixedly connected to the bottom of both sides of the U-shaped cover 208. The inclined grooves 209 cooperate with the linkage column 207 to convert the horizontal movement into vertical movement, thereby realizing the three-dimensional positioning of the plate.

[0032] A support column is slidably connected to the middle of the connecting block 210, and a first spring 212 is sleeved on the outside of the support column. A fixing pad 211 is fixedly connected to the bottom end of the support column; the first spring 212 provides a strong and stable clamping force.

[0033] Among them, an upper pressure roller 213 is fixedly installed on one side of the U-shaped cover 208, and the upper pressure roller 213 is located above the side pressure roller 205; the upper and lower pressure rollers work together to form a three-point positioning system, which effectively prevents the plate from shifting.

[0034] Among them, a scraping component 3 is provided between the two pairs of electric rollers 102; this component simultaneously removes surface oil stains during the conveying of the sheet material, thereby improving production efficiency.

[0035] The electric actuator 202 is fixedly connected to the housing 101, and a ball is rotatably connected to the bottom of the arch frame 201. The ball fits against the outer surface of the electric roller 102. The ball structure reduces frictional resistance and ensures smooth movement of the arch frame 201.

[0036] The top end of the first spring 212 is fixedly connected to the connecting block 210, the bottom end of the first spring 212 is fixedly connected to the fixing pad 211, and the fixing pad 211 is fixedly connected to the top surface of the arch frame 201; this connection method ensures effective transmission of spring force and facilitates maintenance.

[0037] The linkage column 207 is slidably connected to the inclined groove 209; the inclined groove 209 is designed with a 45° inclination angle.

[0038] The scraping assembly 3 includes a suspension rod 301 located between two arch frames 201 on the same side, and a number of crossbars 302 are slidably connected between the two suspension rods 301; this suspension structure enables the oil scraping device to adapt to changes in the thickness of the plate.

[0039] Both ends of the crossbar 302 are fitted with mounting pads 303 and second springs 304, and a mating hole 305 is provided in the middle of the crossbar 302;

[0040] The mating hole 305 is a rectangular hole, and the mating post 306 is connected through the mating hole 305; the rectangular hole design prevents the scraper 308 from rotating and ensures the oil scraping angle is stable.

[0041] A scraper 308 is fixedly connected to the bottom end of the mating post 306, and a stud 307 is fixedly connected to the top end of the mating post 306; the modular design facilitates quick replacement of worn parts.

[0042] The scraper 308 is located above the gap between the two sets of electric rollers 102, and the scraper 308 is set at an angle.

[0043] Mounting pad 303 is fixedly connected to crossbar 302, one end of second spring 304 is fixedly connected to mounting pad 303, and the other end of second spring 304 is fixedly connected to crossbar 302; this symmetrical structure ensures that the crossbar 302 is relatively centered.

[0044] The diameter of the stud 307 is not greater than the width of the mating post 306. The stud 307 is threadedly connected to the nut 309. The threaded connection facilitates the adjustment of the working height of the scraper 308 and prevents the stud 307 from falling off.

[0045] Working principle: Before using this type of cold rolling feeder for aluminum sheet and strip production, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 6As shown, when the sheet material is fed into the electric roller conveyor 1 via the electric roller 102, the electric push rod 202 is activated, causing the arch frame 201 to move and approach the sides of the sheet material until the side pressure rollers 205 clamp the sides of the sheet material. The continued movement of the arch frame 201 causes the moving plate 204 to slide inside the relief groove 203, thus ensuring that the arch frame 201 approaches the sheet material while the position of the side pressure rollers 205 remains unchanged. The movement of the arch frame 201, through the support rod, causes the U-shaped cover 208 and the upper pressure roller 213 to move horizontally simultaneously. The movement causes the connecting column 207 to slide within the inclined groove 209. Under the transmission structure of the connecting column 207 and the inclined groove 209, the upper pressure roller 213 moves horizontally and vertically until it presses vertically onto the top of the plate. In conjunction with the electric roller 102, the lateral and top / bottom surfaces of the plate are positioned in one go. This ensures that the plate remains centered and straight during transportation and oil scraping, preventing vibration and uneven friction during oil scraping that could cause the plate to tilt and affect subsequent processing.

[0046] As the U-shaped cover 208 descends, the suspension rod 301 also descends. When the upper pressure roller 213 presses down on the top surface of the plate, the scraper 308 can adhere to the surface of the plate and move with the plate. During transportation, the scraper 308 moves and scrapes oil synchronously. The sequential scraping of oil by multiple scrapers 308 can achieve thorough oil scraping. The inclined scraper 308 also has a guiding effect on the oil when scraping, causing the oil to fall from the side of the plate. By placing a basin on the inner bottom surface of the electric roller conveyor 1, the oil can be collected.

[0047] When the suspension rod 301 moves horizontally with the U-shaped cover 208, the elastic force of the second spring 304 will keep the crossbar 302 in a position relative to the middle of the plate. Through the docking hole 305 and the docking post 306, docking can be achieved and the rotation of the scraper 308 can be prevented. By removing the nut 309, not only can the scraper 308 be replaced, but the initial position of the scraper 308 can also be finely adjusted.

[0048] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
