Description

Technical Field

[0001] This utility model relates to the field of aluminum cover processing technology, specifically to an aluminum sheet cutting device for aluminum cover processing. Background Technology

[0002] Aluminum sheet cutting is a crucial pre-processing step in packaging manufacturing, its core value lying in providing standardized raw materials for subsequent bottle cap forming. In industries such as beverages, food, pharmaceuticals, and cosmetics, aluminum bottle caps have become the mainstream choice for packaging sealing due to their excellent sealing performance, corrosion resistance, and recyclability. The aluminum sheet cutting process directly determines the utilization rate of raw materials and the quality stability of the final product—by precisely dividing large aluminum coils or plates into circular pieces of specific diameters, it avoids the efficiency bottleneck of manual cutting and ensures the dimensional consistency of each aluminum cap substrate. The industrial application of this process significantly reduces packaging production costs: automated cutting equipment can increase aluminum utilization to over 90%, reducing material waste by 15%–20% compared to traditional manual cutting; at the same time, standardized circular piece specifications provide compatibility guarantees for subsequent stamping, printing, and injection molding processes, enabling modern production lines to achieve high-speed continuous production of 300–500 aluminum caps per minute. From a sustainable development perspective, precise cutting also reduces the generation of aluminum processing waste. Combined with a recycling system, it can achieve 100% recycling of waste materials, which is highly consistent with the global green packaging concept.

[0003] The existing technology has the following shortcomings: The existing technology, in the publication number CN210937353U, "An aluminum sheet cutting device for aluminum cover processing", "includes a support frame, a connecting frame, a top cover, a driving device, a limiting device and a lifting device. The top of the support frame is connected to the bottom of the connecting frame, and the top of the connecting frame is connected to the bottom of the top cover. The driving device, the limiting device and the lifting device are all located inside the connecting frame. The driving device includes a driving motor, a fixing bolt, a support seat, a positioning knife seat and a cutting tool. The output shaft of the driving motor is connected to the top of the support seat."

[0004] The aforementioned structure, through the inclusion of a support frame, connecting frame, top cover, drive device, limiting device, and lifting device, solves two problems that arise when wrapping bottle caps with cut aluminum sheets due to the inconsistent sizes of the bottle caps: firstly, excess aluminum sheets require manual trimming; secondly, excessive aluminum sheets fail to completely cover the bottle caps, affecting their aesthetic appeal. However, current aluminum sheet cutting equipment has a significant deficiency in the automated collection process, directly impacting production safety and efficiency. After cutting the aluminum sheets, the lack of an automatic collection system results in the cut caps being scattered haphazardly within a 0.5-1.2 square meter work area below the equipment. Operators must manually collect these caps every 15-20 minutes, requiring an average of 60-80 bending over to pick them up during an 8-hour workday. This operating method presents multiple safety hazards: First, there is an overlap of approximately 30cm between the cutting station and the collection area, which could cause operators to accidentally enter the working range of the still-operating cutting blades. Second, the edges of the scattered aluminum caps are sharp (with a sharp cutting angle of approximately 45°), making hand collection prone to cuts. These safety hazards not only threaten worker safety but also reduce equipment utilization by approximately 18% due to frequent downtime for inspections, severely impacting production efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an aluminum sheet cutting device for aluminum cap processing, which solves the safety hazards associated with manually collecting aluminum caps.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an aluminum sheet cutting device for aluminum cover processing, comprising a worktable, a tray, a cylinder, and a pressing block. The tray is disposed on the side of the worktable, the cylinder is disposed on the top of the worktable, the pressing block is disposed on the lower end of the cylinder, a control panel is disposed on the side of the worktable, and a motor is disposed inside the worktable.

[0007] A swing dial is provided in the middle of the workbench.

[0008] The workbench also includes an embedded groove and an arc-shaped baffle. The embedded groove is formed on the upper surface of the workbench, and the arc-shaped baffle is welded to the corner of the upper surface of the workbench.

[0009] As a preferred technical solution of this utility model, the embedded groove has an overall arc-shaped structure, with its two ends extending to the side end of the workbench, and a circular inner groove structure is provided in the middle of the embedded groove at the workbench position.

[0010] As a preferred technical solution of this utility model, the swing dial also includes a driven gear, a drive gear, a dual-axis positioning frame, a swing arm, comb teeth, and a support pulley. The driven gear and the drive gear are both provided with a shaft structure passing through them. The shaft structure in the middle of the driven gear is inserted into the middle of the swing dial, and the upper and lower ends of the shaft are respectively movably connected to the two ends inside the worktable.

[0011] As a preferred embodiment of this utility model, the drive gear is sleeved on the bottom of the motor, the dual-axis positioning frame is sleeved on the outer periphery of the shaft in the middle of the drive gear and the driven gear, and a bearing ring is provided at the connection.

[0012] As a preferred technical solution of this utility model, the swing arm is fixedly connected to the side end of the swing dial, and its bottom is at the same level as the middle of the worktable. The comb teeth are fixedly installed at the bottom end of the swing arm, and the support pulley is movably connected to the bottom of the swing arm near the outer end.

[0013] As a preferred embodiment of this utility model, the supporting pulley is embedded in the inner groove, and the direction of the supporting pulley is consistent with that of the inner groove.

[0014] As a preferred technical solution of this utility model, the bottom of the swing arm facing the swing dial has a rectangular groove structure, and the comb teeth are distributed at the bottom of the section.

[0015] Compared with the prior art, this utility model provides an aluminum sheet cutting device for aluminum cover processing, which has the following beneficial effects:

[0016] An aluminum sheet cutting device for processing aluminum caps includes a swing dial, a driven gear, a drive gear, a dual-axis positioning frame, a support pulley, and an inner groove. In use, the operator controls the motor and cylinder via a control panel. After placing a circular aluminum sheet into the cutting area below the pressure block, the cylinder controls the pressure block to press down and cut the aluminum sheet. The pressure block then moves back up to its original position. The material cut into aluminum caps falls onto the upper part of the worktable. The motor then starts, driving the driven gear to rotate. The rotation of the driven gear drives the swing dial to rotate via the central shaft, causing the swing arm to swing synchronously. During the swing arm's swing, the support pulley at its bottom moves along a fixed arc within the inner groove. During this process, the comb teeth at the bottom of the swing arm push the aluminum cap along the arc surface, ensuring it is fully inserted into the tray at the side of the worktable. An arc-shaped baffle prevents the aluminum cap from detaching from the corner.

[0017] Through the above setup and process, this device, compared to existing aluminum sheet cutting devices for aluminum cap processing, utilizes a self-collecting structure for aluminum caps by incorporating a swing dial, swing arm, driven gear, and drive gear. This eliminates the need for manual collection of aluminum caps below the cutting mechanism, and the motor and cylinder work in tandem, increasing automation while preventing workers from directly contacting the hazardous cutting area. This improves the safety of aluminum sheet cutting operations. Attached Figure Description

[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] In this embodiment: an aluminum sheet cutting device for aluminum cover processing includes a workbench 1, a tray 2, a cylinder 3, and a pressing block 4. The tray 2 is disposed on the side of the workbench 1 and collects aluminum covers. The cylinder 3 is disposed on the top of the workbench 1 and drives the pressing block 4. The pressing block 4 is disposed at the lower end of the cylinder 3 and cuts aluminum sheets. A control panel 5 is disposed on the side of the workbench 1 and controls the motor 7 and the cylinder 3 in real time. The motor 7 is disposed inside the workbench 1 and controls the drive gear 602.

[0026] A swing dial 6 is provided in the middle of the workbench 1, which controls the rotation of the swing arm 604.

[0027] The workbench 1 also includes an embedded groove 101 and an arc-shaped baffle 102. The embedded groove 101 is formed on the upper end face of the workbench 1, and the arc-shaped baffle 102 is welded to the upper corner of the workbench 1. The arc-shaped baffle 102 prevents the aluminum cover from being pushed off from the corner and guides the aluminum cover.

[0028] In this embodiment, the embedded groove 101 has an overall arc-shaped structure, with its two ends extending to the side of the worktable 1. A circular inner groove structure is provided in the middle of the embedded groove 101 at the worktable 1 position. The swing dial 6 also includes a driven gear 601, a drive gear 602, a dual-axis positioning frame 603, a swing arm 604, a comb tooth 605, and a support pulley 606. Both the driven gear 601 and the drive gear 602 have a shaft structure passing through them. The shaft structure in the middle of the driven gear 601 is inserted into the middle of the swing dial 6, and the upper and lower ends of the shaft are movably connected to the two ends inside the worktable 1.

[0029] Specifically, such as Figure 3 and Figure 5 As shown, the drive gear 602 drives the driven gear 601, and through the central shaft structure, drives the upper swing dial 6, so that the swing arm 604 can sweep over a wide range, and the sweeping range is the collection range of the aluminum cover.

[0030] It should be noted that the rotation speed of the swing arm 604 and the swing dial 6 is controlled by the motor 7, and its rotation speed remains stable to prevent the centrifugal force from sweeping the aluminum cover away.

[0031] In this embodiment, the drive gear 602 is sleeved on the bottom of the motor 7, the dual-axis positioning frame 603 is sleeved on the outer periphery of the shaft in the middle of the drive gear 602 and the driven gear 601, and a bearing ring is provided at the connection; the swing arm 604 is fixedly connected to the side end of the swing dial 6, and the bottom is kept at the same level as the middle of the worktable 1; the comb teeth 605 are fixedly installed on the bottom end of the swing arm 604; and the support pulley 606 is movably connected to the bottom of the swing arm 604 near the outer end.

[0032] Specifically, such as Figure 1 Figure 3 as well as Figure 4 As shown, when the comb teeth 605 swing with the swing arm 604, they drive the aluminum cover through the gap between two adjacent sets of comb teeth 605. Meanwhile, when the support pulley 606 rolls in the inner groove 101, it ensures the stability of the swing arm 604 and reduces friction.

[0033] In this embodiment, the support pulley 606 is embedded in the inner groove 101, and the direction of the support pulley 606 is consistent with that of the inner groove 101; a rectangular groove structure is provided on the upward section of the bottom of the swing arm 604 facing the swing dial 6, and the comb teeth 605 are all distributed at the bottom of this section.

[0034] The working principle and usage process of this utility model are as follows: When using this device, the operator controls the motor 7 and cylinder 3 through the control panel 5. After the operator places the circular aluminum plate into the cutting area below the pressure block 4, the cylinder 3 controls the pressure block 4 to press down and cut the aluminum plate. Then, the pressure block 4 moves up and resets. At this time, the material cut into aluminum caps falls onto the upper end of the worktable 1. The motor 7 starts and drives the driven gear 601 to rotate through the drive gear 602. When the driven gear 601 rotates, it drives the swing dial 6 to rotate through the central shaft. The swing arm 604 swings synchronously. When the swing arm 604 swings, the support pulley 606 at its bottom end moves along a fixed arc in the embedded groove 101. During the above process, the comb teeth 605 at the bottom of the swing arm 604 push the aluminum cap along the arc surface during the swing and make it completely enter the tray 2 on the side of the worktable 1. The arc surface baffle 102 prevents the aluminum cap from falling off from the corner.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model 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 this utility model should be included within the protection scope of this utility model.
