Description

Technical Field

[0001] This utility model relates to the field of air extraction structure technology, and in particular to an air extraction structure for a screw packing machine. Background Technology

[0002] Screws are a common type of fastener with a wide range of applications. They are frequently seen in everyday items, production machinery, and construction. During the screw production process, the finished screws need to be collected and packaged. The machine used in the screw packaging process is called a screw packaging machine. The screw packaging machine outputs the screws into screw packaging bags. Once the number of screws in the packaging bag reaches a certain amount, the screw packaging machine seals the packaging bag.

[0003] An existing authorized publication number CN216546926U discloses an air extraction structure for a screw packaging machine. It includes a mounting platform, an air extraction component, and a moving component. The air extraction component includes an air extraction needle, an air extraction cylinder, and an air extraction pipe. The moving component includes a moving cylinder and a cylinder mounting plate. The air extraction needle and the air extraction cylinder are connected. The air extraction pipe is also connected to the air extraction cylinder. The cylinder rod of the moving cylinder is fixedly connected to the air extraction cylinder. The cylinder mounting plate is connected to the mounting platform, and the moving cylinder is mounted on the cylinder mounting plate. When the screw packaging machine heat-seals the screw packaging bag, the cylinder rod of the moving cylinder extends, moving and driving the air extraction cylinder to move. The air extraction cylinder then moves the air extraction needle towards the screw bag. The air extraction needle penetrates the screw packaging bag, extracting the gas inside. This application improves the packaging efficiency of screws.

[0004] Regarding the aforementioned technologies, the existing air extraction structure has the following drawbacks: the air extraction needle is made of rigid metal. If the screws inside the packaging bag are stacked too high, the needle may directly pierce the screw surface during air extraction, causing scratches on the screw threads and damage to the surface plating (such as the peeling off of zinc or chromium plating), affecting the product's precision and rust resistance. Therefore, this utility model provides an air extraction structure for a screw packaging machine. Utility Model Content

[0005] The purpose of this application is to provide an air extraction structure for a screw packaging machine to solve the problem mentioned in the background art that the air extraction needle is made of rigid metal material, and if the screws are stacked too high in the packaging bag, the needle may directly pierce the surface of the screw during air extraction, causing scratches on the screw threads and damage to the surface plating (such as the peeling off of zinc or chromium plating), affecting the product's precision and rust prevention capabilities.

[0006] To achieve the above objectives, this application provides the following technical solution: a vacuum structure for a screw baling machine, comprising a mounting box, an mounting platform provided on the outer side of the mounting box, a slot provided on the inner side of the mounting platform, a mounting plate and a positioning frame fixedly connected to the bottom two sides of the mounting platform respectively, and a screw separating assembly provided between the mounting plate and the positioning frame; the screw separating assembly includes a placement frame rotatably connected to the mounting plate and the positioning frame, a fixing frame fixedly connected to both sides of the placement frame, a hydraulic push rod fixedly connected to the inner side of the fixing frame, a pressure block fixedly connected to the output end of the hydraulic push rod, and a slot provided on the inner side of the placement frame.

[0011] Preferably, the bottom of the pressure block is provided with a rubber pad, and the outer side of the rubber pad is provided with anti-slip texture.

[0012] In summary, the technical effects and advantages of this utility model are as follows: In this invention, the screw-separating component divides the screw packaging bag into a "product area" and a "vacuuming area". This allows the vacuum needle to be inserted only into the "vacuuming area" during the vacuuming process, avoiding direct insertion into the screw surface, which could cause scratches on the screw threads or damage to the surface plating (such as the peeling off of zinc or chromium plating), thus affecting product precision and rust prevention.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] Example 1: Reference Figure 1-4The present application describes an air extraction structure for a screw baling machine. The structure includes a controller and a power supply. The controller controls electrical components (such as a motor and a telescopic hydraulic cylinder), and the power supply provides power. The structure also includes an oil supply mechanism for the hydraulic cylinder, which is prior art and will not be described in detail here. The system includes a mounting box 1, which serves as the base for the overall air extraction and related components, providing a stable mounting carrier for each component and ensuring the overall structural stability. An mounting platform 2 is provided on the outer side of the mounting box 1 to support key components such as the empty slot 3 and screw separation components, providing an operating platform for the temporary storage and handling of screws. An empty slot 3 is provided on the inner side of the mounting platform 2. A mounting plate 14 and a positioning frame 16 are fixedly connected to the bottom of the mounting platform 2 on both sides. The mounting plate 14 is used to install and fix the motor 15 and provide one-sided rotational support for the placement frame 4. The positioning frame 16 works with the mounting plate 14 to form a bidirectional positioning for the placement frame 4, ensuring its coaxiality during rotation. A screw separation component is provided between the mounting plate 14 and the positioning frame 16. The screw separation component includes a placement frame 4 rotatably connected to the mounting plate 14 and the positioning frame 16, serving as the core supporting component for screw separation operations. It provides placement space for screws and allows for angle adjustment through rotation. Fixing frames 5 are fixedly connected to both sides of the placement frame 4 to fix and install hydraulic push rods 6, providing support for the hydraulic push rods. Rod 6 provides stable mounting support, ensuring stable thrust output. A hydraulic push rod 6 is fixedly connected to the inner wall of the fixing frame 5, serving as a power source to drive the pressure block 18 to achieve linear telescopic movement. The output end of the hydraulic push rod 6 is fixedly connected to the pressure block 18. A slot 12 is provided on the inner side of the placement frame 4 to accommodate the insertion of the suction end of the air extraction component, providing a channel for the air extraction process. A motor 15 is provided on the outer side of the mounting plate 14, serving as a power source for the rotation of the placement frame 4, providing stable rotational driving force. The output end of the motor 15 passes through the mounting plate 14 and is fixedly connected to the placement frame 4, directly transmitting the rotational power of the motor 15 to the placement frame 4, causing the placement frame 4 to rotate around the line connecting the mounting plate 14 and the positioning frame 16. A rotating rod 17 is fixedly connected to the side of the placement frame 4, forming a double-end support structure for the placement frame 4 in cooperation with the motor 15. The rotating rod 17 passes through the positioning frame 16, allowing the placement frame 4 to rotate stably around the axis of the rotating rod 17 and the output end of the motor, improving the smoothness of the rotation process.

[0019] Example 2: Reference Figure 1-4Based on the same concept as in Embodiment 1 above, this embodiment further proposes that a hydraulic telescopic rod 8 be installed at the bottom of the mounting platform 2. The hydraulic telescopic rod 8 can achieve telescopic drive, precisely controlling the displacement of the push plate 9. The push plate 9 is fixedly connected to its output end. The push plate 9 is used to transmit the driving force of the hydraulic telescopic rod 8, driving the vacuum cylinder 10 to move stably. The vacuum cylinder 10 is fixedly connected to its output end. The vacuum cylinder 10 provides a sealed cavity for the vacuuming process, ensuring stable airflow transmission. One end of the vacuum cylinder 10 is fixedly connected to a communicating vacuum needle 11. The vacuum needle 11 can be precisely inserted into the target position to achieve fixed-point vacuuming. The bottom of platform 2 is equipped with a vacuum pump 7, which provides power to the vacuum system and generates negative pressure suction. Its output end is fixedly connected to a vacuum pipe 13, which is used to transport airflow and realize the air path connection between the vacuum pump 7 and the vacuum cylinder 10. The vacuum pipe 13 is connected to the vacuum cylinder 10. The bottom of the pressure block 18 is equipped with a rubber pad, which can buffer the pressure of the pressure block 18 and the contact object to avoid damage to the contact surface, while enhancing the fit and sealing. The outer side of the rubber pad is equipped with anti-slip texture, which can increase the friction between the rubber pad and the contact object, prevent relative sliding, and improve the pressing stability.

[0020] The working principle of this utility model is as follows: A pair of hydraulic push rods 6 drive the pressure block 18 downwards, squeezing and limiting the two corners of the screw packaging bag near the suction needle 11. The motor 15 drives the placement frame 4 to deflect along the rotating rod 17, causing the screw packaging bag to deflect and the end of the placement frame 4 near the suction needle 11 to tilt upwards. This allows the screws inside the packaging bag to slide and accumulate at one end, effectively dividing the packaging bag into a "product area" and a "suction area." The hydraulic telescopic rod 8, via the push plate 9, drives the suction cylinder 10 and suction needle 11 to move and insert into the "suction area" of the screw packaging bag. The suction pump 7, through the suction pipe 13, suction cylinder 10, and suction needle 11, extracts gas from the "suction area," preventing the needle 11 from directly piercing the screw surface during suction, which could cause scratches on the screw threads or damage to the surface plating (such as peeling off zinc or chromium plating), affecting product precision and rust prevention.

[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
