Description

Technical Field

[0001] This utility model relates to the field of aluminum foil processing technology, specifically to an ultra-wide aluminum foil rack. Background Technology

[0002] Aluminum foil is a thin sheet of metal made by repeatedly cold rolling metallic aluminum on a rolling mill. It is typically less than 0.2 mm thick, soft, and has a silvery-white metallic luster. With its excellent barrier properties, aluminum foil effectively blocks oxygen, moisture, light, and microorganisms, keeping packaged items fresh for extended periods. Its excellent thermal conductivity allows for rapid and even heat transfer, making it widely used in food baking and cooking. Furthermore, aluminum foil possesses excellent flexibility and ductility, making it easy to process and shape into various complex forms, facilitating the packaging of diverse products. In addition, aluminum foil is a recyclable material with low energy consumption during recycling, aligning with environmental protection principles. Today, aluminum foil is indispensable in numerous industries, including food packaging, pharmaceutical packaging, electronics, and aerospace, playing a vital role in both daily life and industrial production.

[0003] For example, patent CN220640615U discloses a material rack for multi-roll packaging of aluminum foil, including two square tubes extending horizontally back and forth, with a crossbar connected between the square tubes near the top. The square tubes are provided with two sets of support components, each of which includes a fixed support bar parallel to the crossbar and a movable support bar parallel to the crossbar. The fixed support bar is fixed to the square tube, and the bottom of the movable support bar is provided with adjusting pins at both ends. The adjusting pins extend vertically up and down, and each adjusting pin is provided with a row of adjusting pin holes opened on the square tube and spaced apart along the length of the square tube. The adjusting pin can be pulled out and inserted into an adjusting pin hole. However, existing devices can only be used to place and install aluminum foil of a single width. They lack suitable limiting structures. During transportation or storage, the aluminum foil is prone to sliding or displacement due to inertia or external forces. The aluminum foil surface is fragile. Once it is displaced and rubs against the material rack components, it will cause scratches, indentations and other damage, which seriously affects product quality. Moreover, when the aluminum foil roll is heavy, it is easy to cause the device to tilt, which may lead to the risk of collapse.

[0004] Therefore, in order to solve this problem, we propose an ultra-wide aluminum foil rack. Utility Model Content

[0005] The purpose of this utility model is to provide an ultra-wide aluminum foil rack to solve the problems mentioned in the background art. When using the existing device, it can only place and install aluminum foil of a single width size. It lacks a suitable limiting structure. When transporting or moving the device, the aluminum foil is very easy to slide or shift due to inertia or external force. The surface of the aluminum foil is fragile. Once it shifts and rubs against the rack components, it will cause scratches, indentations and other damage, which seriously affects the product quality. Moreover, when the aluminum foil roll is heavy, it is easy to cause the device to tilt and cause the risk of collapse.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an ultra-wide aluminum foil rack, including a base plate, with support plates symmetrically arranged on the top of the base plate, a U-shaped frame fixedly connected to the middle of the top surface of the support plates, a first motor fixedly connected to the top of the U-shaped frame, the output end of the first motor passing through the U-shaped frame, a gear fixedly connected to the bottom of the output end of the first motor, racks meshing on both sides of the gear, a fixing block fixedly connected to the outer end of the rack, and a limit plate fixedly connected to the inner wall of the fixing block.

[0007] Furthermore, side plates are fixedly connected to both sides of the top of the base plate, and brackets are fixedly connected to the top of the side plates. Limiting grooves are opened on both outer walls of the brackets, and double threaded rods are rotatably connected in the limiting grooves. A second motor is fixedly connected to the outer wall of the left end of the double threaded rod in front of the bracket. Limiting blocks are threaded to both ends of the double threaded rod, and placement rollers are rotatably connected to the inner wall of the limiting blocks.

[0008] Furthermore, the bottom plate has first sliding grooves on both sides of the top, the bottom of the support plate is fixedly connected to a first slider that matches the first sliding groove, the top of the support plate has second sliding grooves evenly opened at both ends, and the bottom of the rack is fixedly connected to a second slider that matches the second sliding groove.

[0009] Furthermore, both ends of the double-threaded rod are movably fitted with protective springs, and the outer ends of the protective springs are fixedly connected to the inner wall of the limiting groove.

[0010] Furthermore, a transmission assembly is provided at one outer end of the double-threaded rod. The transmission assembly includes a pulley fixedly connected to one end of the double-threaded rod, and a belt is sleeved between the two pulleys.

[0011] Furthermore, sleeves are uniformly fixedly connected to the inner wall of the side plate, shock-absorbing springs are fixedly connected to the inner wall of the sleeves, and a plunger rod is fixedly connected to the outer end of the shock-absorbing spring. The outer end of the plunger rod is fixedly connected to the outer wall of the support plate.

[0012] Furthermore, each of the four feet at the bottom of the base plate is fixedly connected with a caster wheel, and a load-bearing spring is sleeved on the pivot at the top of the caster wheel.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This ultra-wide aluminum foil rack adopts a novel structural design, the specific details of which are as follows:

[0014] (1) The ultra-wide aluminum foil rack is driven by the first motor to rotate the gear. The gear and the rack on both sides are meshed and driven to move the rack synchronously in the horizontal direction, thereby adjusting the spacing of the limiting plate to adapt to aluminum foil rolls of different widths. This solves the limitation of existing packaging technology that can only adapt to a single width. The limiting plate forms a rigid physical limiting barrier on both sides of the aluminum foil roll, which effectively resists the inertial force and external force generated during transportation or storage and movement, prevents the aluminum foil roll from sliding or shifting, avoids its fragile surface from directly rubbing against the rack components, eliminates quality hazards such as scratches and indentations from the root, and significantly improves the appearance quality and reliability of the finished aluminum foil.

[0015] (2) The ultra-wide aluminum foil rack is driven by a second motor to rotate a double threaded rod. The reverse thread characteristics at both ends of the double threaded rod cause the limit blocks on both sides to move synchronously towards or away from each other. The spacing between the placement rollers can be adjusted according to the diameter of the aluminum foil roll to adapt to different specifications of aluminum foil rolls. The transmission components ensure that the double threaded rods on both sides rotate synchronously, avoiding the aluminum foil roll from tilting due to asynchronous adjustment on one side, thus enhancing stability. The sleeve, shock-absorbing spring and plunger rod on the inner wall of the side plate form a shock-absorbing structure. When the aluminum foil roll is placed, the plunger rod is compressed into the sleeve, compressing the shock-absorbing spring and buffering the impact of the weight of the aluminum foil roll on the device, preventing the device from tilting or collapsing due to heavy load. The protective springs at both ends of the double threaded rod buffer mechanical stress during the adjustment process, reducing rigid collisions of components and extending service life.

[0016] Furthermore, the first groove of the base plate cooperates with the first slider at the bottom of the support plate, allowing the support plate to slide horizontally and adjust the overall spacing. The second groove at the top of the support plate cooperates with the second slider at the bottom of the rack to ensure that the rack moves smoothly and avoids shaking that could affect the limiting accuracy.

[0024] 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.

[0025] This utility model provides the following technical solution: a material rack for ultra-wide aluminum foil.

[0026] Example 1: An ultra-wide aluminum foil rack, through the arrangement of gears 13, racks 14, and limiting discs 15, allows the limiting discs 15 to restrict the aluminum foil rolls on the placement rollers 231. This prevents existing racks from only accommodating aluminum foil of a single width, which, due to the lack of an effective limiting structure, easily slip and shift during transportation or storage. Furthermore, the aluminum foil's fragile surface rubs against the rack, causing scratches and indentations, severely affecting product quality. Figure 1 - Figure 5As shown, an ultra-wide aluminum foil rack includes a base plate 1. Support plates 11 are symmetrically arranged on the top of the base plate 1. A U-shaped frame 12 is fixedly connected to the center of the top surface of the support plate 11. A first motor is fixedly connected to the top of the U-shaped frame 12. The output end of the first motor passes through the U-shaped frame 12. A gear 13 is fixedly connected to the bottom of the output end of the first motor. Racks 14 are meshed on both sides of the gear 13. A fixing block is fixedly connected to the outer end of the rack 14. A limiting plate 15 is fixedly connected to the inner wall of the fixing block. Side plates 2 are fixedly connected to both sides of the top of the base plate 1. A bracket 21 is fixedly connected to the top of the side plates 2. Limit grooves 211 are formed on the outer walls of both sides of the bracket 21. A double-threaded rod 22 is rotatably connected within the limiting groove 211. The left side of the double-threaded rod 22 at the front of the bracket 21... A second motor is fixedly connected to the outer wall of the end. Both ends of the double threaded rod 22 are threadedly connected to limit blocks 23. A placement roller 231 is rotatably connected to the inner wall of the limit block 23. The top of the base plate 1 has first sliding grooves on both sides. The bottom of the support plate 11 is fixedly connected to a first slider that matches the first sliding groove. The top of the support plate 11 has second sliding grooves evenly opened at both ends. The bottom of the rack 14 is fixedly connected to a second slider that matches the second sliding groove. Both ends of the double threaded rod 22 are movably sleeved with protective springs 221. The outer end of the protective springs 221 is fixedly connected to the inner wall of the limit groove 211. A transmission assembly 24 is provided on one outer end of the double threaded rod 22. The transmission assembly 24 includes a pulley fixedly connected to one end of the double threaded rod 22. A belt is sleeved between the two pulleys.

[0027] First, the aluminum foil roll is placed on top of the placement roller 231. Then, the first motor is started, and its output shaft drives the gear 13 to rotate clockwise or counterclockwise. The meshing transmission between the gear 13 and the racks 14 on both sides converts the circular motion into linear motion. The second slider at the bottom of the rack 14 slides directionally along the second groove at the top of the support plate 11. The rack 14 drives the limiting plate 15 to move synchronously through the fixing block. The inner side of the limiting plate 15 is lined with a high-polymer nylon pad, which makes flexible contact with the end face of the aluminum foil roll to avoid rigid damage. Then, the second motor is started. Its output end drives the double threaded rod 22 to rotate through a coupling. The reverse thread structure at both ends of the double threaded rod 22 causes the limiting block 23 to move in opposite directions. The guide key at the bottom of the limiting block 23 is embedded in the limiting groove 211. The double threaded rods 22 on both sides are synchronously linked through the transmission component 24. The active pulley is coaxially fixed with the double threaded rod 22. The high-strength synchronous belt transmits torque. The driven pulley drives the secondary shaft double threaded rod 22 to rotate synchronously. The surface of the placement roller 231 is chrome-plated to ensure that the aluminum foil roll rolls smoothly without jamming.

[0028] Example 2: Unlike Example 1, the sleeve 3, plunger rod 31, and shock-absorbing springs, among other components, allow the aluminum foil roll to press down on the placement roller 231 while being cushioned by the shock-absorbing springs. This prevents the device from tilting and collapsing when the aluminum foil roll is heavy. Figure 6As shown, sleeves 3 are evenly fixedly connected to the inner wall of the side plate 2, and shock-absorbing springs are fixedly connected to the inner wall of the sleeves 3. A plunger rod 31 is fixedly connected to the outer end of the shock-absorbing spring, and the outer end of the plunger rod 31 is fixedly connected to the outer wall of the support plate 11. Universal wheels are fixedly connected to the four feet at the bottom of the base plate 1, and load-bearing springs are sleeved on the pivot at the top of the universal wheels.

[0029] When the aluminum foil roll is placed, its weight is transferred to the support plate 11 through the placement roller 231. The support plate 11 pushes the plunger rod 31 to compress the shock-absorbing spring in the sleeve 3. The spring absorbs the impact energy through elastic deformation, reducing the vibration of the device. When the placement roller 231 is adjusted, the protective spring 221 buffers the mechanical force between the double threaded rod 22 and the limiting block 23 to avoid rigid impact. The caster wheel enables the device to move flexibly. When carrying the aluminum foil roll, the load-bearing spring on the caster wheel shaft is compressed to buffer the impact of uneven ground or movement, keep the device stable, and prevent the aluminum foil roll from shifting.

[0030] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
