Description

Technical Field

[0001] This application relates to the field of punching equipment, and in particular to a perforation forming apparatus for Hanas curtains. Background Technology

[0002] Hanas blinds are a new type of decorative curtain product that combines aesthetics, practicality, and functionality, and are widely used in homes, offices, hotels, and commercial spaces. As people's demands for home décor continue to rise, Hanas blinds, with their unique shapes and textures, are gaining popularity among consumers. Hanas blinds are typically made of a special woven structure or multi-layered textile materials, possessing a certain thickness and strength. The production process involves multiple steps, among which the perforation process is an essential and crucial step. Perforations along the edges or at designated locations on the Hanas blinds facilitate the subsequent installation of hooks, connectors, or fixing devices, ensuring smooth installation and use of the blinds.

[0003] like Figure 3 As shown, the existing Hanas curtain 900 has several through holes 910. The perforation process for these through holes 910 mostly employs a manual mechanical punching method. Operators must place the Hanas curtain one by one on the punching die and manually press the punching mechanism to create the holes. This method has the following disadvantages: Firstly, manual operation is physically demanding, and prolonged work can easily lead to operator fatigue and reduce production efficiency. Secondly, due to the lack of precision in manual positioning, quality problems such as punching position deviation and uneven hole diameter can easily occur, affecting the product's appearance and performance. Furthermore, manually operated punching equipment poses certain safety hazards; improper operation may lead to accidental injury or hand trapping accidents.

[0004] With the expansion of production scale and the increasing market demand for high-quality products, existing manual punching methods are no longer sufficient to meet the requirements of efficient, precise, and safe punching. To address this issue, some companies have attempted to introduce pneumatic punching devices, using cylinders to drive punches for automated punching. However, existing pneumatic punching devices are mostly used for punching ordinary fabrics or thinner materials. For materials like Hanas curtains, which have a certain thickness and structural complexity, problems remain, including inaccurate positioning, easy punch misalignment, punch jamming, and insufficient mold frame stability. Furthermore, some existing devices lack flexible adjustment functions, making it difficult to adapt to Hanas curtains of different specifications and edge shapes, thus limiting their application.

[0005] On the other hand, traditional pneumatic punching devices mostly rely on manual buttons for operation and control. This method is relatively inefficient for mass production, and requires operators to use both hands, increasing operational complexity. Some devices lack emergency control systems, meaning that in the event of circuit or control system failures, the cylinders cannot be manually shut down or controlled, posing a safety hazard. For the demand for efficient, safe, and precise punching, current technology has yet to provide a dedicated punching and forming device that is structurally sound, accurately positioned, easy to operate, and equipped with emergency control functions.

[0006] To address the aforementioned issues, there is an urgent need for a perforation forming device that is automatably controlled, possesses high positioning accuracy, is suitable for perforation processing of the special structure of Hanas curtains, and combines convenient operation with safety. This device should have the following technical features: First, it should achieve automatic extension and retraction of the punch through pneumatic control, avoiding repetitive manual labor and improving punching efficiency; second, it should achieve precise positioning of the Hanas curtain through the setting of positioning plates, axial positioning plates, and positioning grooves, ensuring consistent punching positions and standard hole positions; third, it should improve the guidance and smoothness of the punch during movement through a mold frame structure equipped with guide pillars, guide sleeves, and lubrication oil grooves, reducing jamming or misalignment problems; fourth, it should use a foot switch to operate the solenoid valve, freeing the operator's hands and improving operational convenience, while also providing a manual emergency button to offer a backup operation mode in case the foot switch fails, enhancing safety.

[0007] In summary, existing Hanas curtain perforation processes still have shortcomings in terms of efficiency, positioning accuracy, automation, and safety, failing to meet the demands of current mass production and high-standard processing. Therefore, there is an urgent need to develop a new type of Hanas curtain perforation forming device with a reasonable structural design, precise positioning, convenient operation, flexible control, and emergency response capabilities to solve the aforementioned technical problems in existing technologies and meet the demands of modern Hanas curtain production for efficient and high-quality perforation processing.

Detailed Implementation

[0039] The following is in conjunction with the appendix Figure 1-2 , Figure 4 This application will be described in further detail.

[0040] This application discloses a perforation forming device for Hanas curtains.

[0041] like Figure 1 , Figure 2As shown, this utility model provides a perforation forming device for Hanas curtains, including a perforation forming device body. The perforation forming device body includes a mold frame 120. A cylinder 110 is provided at the upper end of the mold frame 120. The air circuit of the cylinder 110 is connected to a pneumatic solenoid valve 200. The pneumatic solenoid valve 200 is electrically connected to a foot switch 300. By operating the foot switch 300 to open and close the pneumatic solenoid valve 200, the pneumatic solenoid valve 200 sends a control command to the cylinder 110, driving the cylinder 110 to perform axial extension and retraction of the cylinder head.

[0042] In this embodiment, the mold frame 120 includes a top plate 121, and side plates 122 are provided on both sides of the lower end of the top plate 121. The lower ends of the side plates 122 are fixedly connected to the upper end face of the bottom plate 123. The top plate 121, side plates 122 and bottom plate 123 are combined into an integrated structure. Through the integrated structural design, the overall structure of the mold frame is more stable and can withstand the impact force of the cylinder during operation, avoiding the displacement of the punch 140 due to structural loosening and causing perforation deviation.

[0043] A cylinder 110 is fixedly installed on the upper end surface of the top plate 121. Guide sleeves 190 are symmetrically arranged on both sides of the cylinder 110 on the top plate 121. A guide post 180 is slidably connected inside the guide sleeve 190. The lower end of the guide post 180 extends into the lower part of the top plate 121 and is fixedly connected to the pressure plate 130. The cooperation between the guide post 180 and the guide sleeve 190 ensures the guiding accuracy and stability of the pressure plate 130 and the punch 140 during the up and down movement, and avoids the punch 140 from failing to pierce or being damaged due to skew.

[0044] The pressure plate 130 is provided with several punches 140, the heads of which extend downwards. The base plate 123 is provided with several through holes 1231, the positions of which are aligned with the center lines of the corresponding punches 140, and the diameter of the through holes 1231 is larger than the diameter of the punches 140. When the cylinder 110 drives the cylinder head to press down, the punches 140 move downwards along the guide post 180 under the drive of the pressure plate 130. The heads of the punches 140 pass through the through holes 1231 on the base plate 123 to perform a perforation operation on the Hanas curtain located below it, thereby completing efficient perforation.

[0045] In a preferred embodiment, a positioning plate 150 is provided on the side of the base plate 123 facing the punch 140, and an axial positioning plate 160 is provided on the side of the base plate 123 perpendicular to the positioning plate 150. The height of the axial positioning plate 160 is lower than that of the positioning plate 150. The positioning plate 150 and the axial positioning plate 160 together form an L-shaped positioning structure, which is used to limit the lateral and longitudinal positions of the Hanas curtain during perforation, prevent it from slipping or deviating during perforation, and ensure the accuracy of the perforation position.

[0046] In a further optimized configuration, the solenoid valve 200 is electrically connected to the foot switch 300 via a power cord 310. One end of the power cord 310 is connected to the solenoid valve 200, and the other end is connected to the foot switch 300. The foot switch 300 controls the solenoid valve 200, thereby controlling the extension and retraction of the cylinder head of the cylinder 110. This structure simplifies the control system, is easy to operate, and frees up the operator's hands. The cylinder can be started and stopped using only the foot, ensuring high safety.

[0047] In another preferred embodiment, the cylinder 110 is provided with no fewer than two air pipe connectors 400, and the solenoid valve 200 is provided with no fewer than four air pipe connectors 400. Two air pipe connectors 400 of the solenoid valve 200 are connected to two air pipe connectors 400 of the cylinder 110 via air pipes 500, and the other two air pipe connectors 400 of the solenoid valve 200 are connected to the air pipes of an external air source. The pneumatic solenoid valve 200 controls the opening, closing, and reversing of the air passage of the cylinder 110, enabling the cylinder 110 to perform forward and reverse axial extension and retraction movements when it is working, thereby driving the punch 140 to move up and down to achieve the piercing operation.

[0048] To further improve the user experience, a buffer pad is installed on the surface of the pressure plate 130 to reduce the impact and prevent noise when the punch 140 returns to its original position. By setting the buffer pad, the mechanical impact generated when the punch 140 returns to its original position is effectively reduced, the service life of the equipment is extended, and the comfort of use is improved.

[0049] In a preferred embodiment, the punch 140 and the pressure plate 130 are connected by a thread and a limiting nut is provided to adjust the extension length of the punch 140. By adjusting the position of the limiting nut, the extension length of the punch 140 can be flexibly adjusted to adapt to different thicknesses of Hanas curtain materials, realize multi-specification perforation requirements, and improve the applicability and versatility of the equipment.

[0050] Furthermore, the positioning plate 150 is provided with a positioning groove, the shape of which matches the edge structure of the Hanas curtain to achieve precise positioning during perforation. The positioning groove enables the Hanas curtain to automatically align when placed, further improving positioning accuracy, reducing manual adjustment time, and increasing perforation efficiency.

[0051] In another embodiment, the outer surface of the guide post 180 is provided with a lubricating oil groove to provide lubrication between the guide post 180 and the guide sleeve 190 to reduce friction. By setting the lubricating oil groove and regularly adding lubricating oil, the frictional resistance between the guide post 180 and the guide sleeve 190 is reduced, wear is reduced, the service life of the equipment is extended, and the smoothness of the up and down movement of the punch 140 is ensured.

[0052] To improve operational safety and reliability, a manual emergency button is provided on the solenoid valve 200. When the foot switch 300 fails, the cylinder head extension and retraction control of the cylinder 110 can be achieved through the manual emergency button, thereby ensuring that the equipment can still operate safely under special circumstances and avoiding damage to the equipment or workpiece due to control failure.

[0053] Reference Figure 4 The perforation forming device body 100 is installed on a corner of the table 800. The Hanas curtain is placed on the table and moved horizontally to complete the perforation process of the Hanas curtain.

[0054] The number and position of the punches 140 of the perforation forming device body 100 can be configured according to the number and position of the through holes 910 of the Hanas curtain. In application, the pressure plate 130 with the corresponding number and position of punches 140 is replaced and installed accordingly.

[0055] The implementation principle of the perforation forming device for Hanas curtain in this embodiment is as follows: When the operator presses the foot switch 300, the foot switch sends an electrical signal to the solenoid valve 200 through the power line 310. After the solenoid valve 200 responds to the signal, it opens the air circuit and controls the air source to enter the cylinder 110, pushing the cylinder head of the cylinder 110 to move axially downward. When the cylinder head is pressed down, the guide post 180 (fixedly connected to the cylinder head) drives the pressure plate 130 and the punch 140 to move precisely downward along the guide sleeve 190. Under the push of the pressure plate 130, the punch 140 vertically passes through the through hole 1231 on the bottom plate 123, realizing the perforation operation of the Hanas curtain placed in the L-shaped positioning structure of the positioning plate 150 and the axial positioning plate 160. The positioning groove on the positioning plate 150 matches the edge structure of the Hanas curtain, ensuring the accurate positioning of the perforation position and avoiding workpiece displacement. After the perforation is completed, the foot switch 300 is released, and the electric... The solenoid valve 200 reverses and cuts off or switches the air path, causing the cylinder head of cylinder 110 to retract in the opposite direction, driving the pressure plate 130 and punch 140 back to their initial positions along the guide post 180. During the return process, the punch 140 contacts the buffer pad on the pressure plate 130, which absorbs the return impact and reduces mechanical vibration and noise. If the foot switch 300 fails during operation, the cylinder 110 can be manually controlled via the manual emergency button on the solenoid valve 200 to ensure safe operation of the equipment and continuous production. In addition, the punch 140 and the pressure plate 130 are connected by threads and equipped with a limit nut, which allows for flexible adjustment of the extension length of the punch 140 according to different thicknesses of Hanas curtains to meet various perforation requirements. The outer surface of the guide post 180 is provided with a lubricating oil groove. By adding lubricating oil, the friction between the guide post 180 and the guide sleeve 190 is reduced, wear is reduced, and the smoothness of the punch movement is ensured.

[0056] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
