Technical Field

[0001] This utility model belongs to the field of nonwoven packaging equipment and relates to a mechanical fixing and locking mechanism. Background Technology

[0002] In the field of nonwoven packaging equipment, the frame is a key component. Frame one serves as the equipment base, firmly fixed to the ground, and bears the important task of supporting the entire equipment, ensuring the stability of the equipment during operation. Frame two is mainly used to place the packaging substrate, providing support and precise positioning to ensure that the packaging substrate can accurately participate in subsequent packaging processes.

[0003] In actual production, frame one and frame two need to be fixed and detached according to different production requirements to achieve flexible adjustment and efficient operation of the equipment. However, the mechanical fixing and locking mechanisms currently used in the industry are complex in structure, which not only increases manufacturing costs but also makes the overall space occupied by the equipment large, limiting its layout in limited factory space. Moreover, the complex structure makes the operation process cumbersome, requires high skill levels from operators, and brings great difficulties to installation and maintenance work, affecting equipment maintenance efficiency and production progress.

Positioning hooks are provided on both sides of the sliding plate and are eccentrically mounted on the second frame via support pins, making the positioning hooks heavier at the bottom and lighter at the top. A notch is provided on the first frame, allowing the lower end of the positioning hook to be inserted into the notch when not under force. The drive mechanism drives the sliding plate to move up and down, and drives the positioning hooks to rotate around the support pins, thereby locking or disengaging the positioning hooks from the first frame.

[0010] As a further improvement of one embodiment of the present utility model, the frame is provided with a boss, and the middle part of the slide plate has a groove to avoid the boss.

[0011] As a further improvement of one embodiment of the present invention, the boss has a vertical channel in the middle, and the frame two is provided with a positioning post that can be inserted into the vertical channel.

Example

[0039] See Figures 1-4 As shown, a mechanical fixing and locking mechanism is used to achieve a stable connection and flexible disengagement between frame 1 and frame 7, so as to meet the usage requirements of nonwoven packaging equipment under different working conditions.

[0040] The mechanical locking mechanism includes a slide plate 6. A drive mechanism for vertical movement of the slide plate 6 is mounted on a second frame 7. Positioning hooks 2 are located on both sides of the slide plate 6. The positioning hooks 2 are eccentrically mounted on the second frame 7 via a support pin 4, making the bottom of the positioning hooks 2 heavier than the top. A notch is provided on the first frame 1, allowing the lower end of the positioning hook 2 to be inserted into the notch when not under force. The drive mechanism drives the slide plate 6 to move up and down, and drives the positioning hooks 2 to rotate around the support pin 4, thereby locking or disengaging the positioning hooks 2 from the first frame 1.

[0041] In this embodiment, the slide plate 6, as a key component driving the positioning and fixing hook 2, performs vertical linear motion under the action of the drive mechanism. Its two sides interact with the positioning and fixing hook 2, and its vertical movement drives the positioning and fixing hook 2 to rotate around the support pin 4.

[0042] Specifically, the drive mechanism includes a cylinder, a guide shaft 9, and a guide sleeve 8. The cylinder and guide sleeve 8 are fixedly mounted on the frame 7. The guide shaft 9 is located inside the guide sleeve 8. The lower end of the guide shaft 9 is fixedly connected to the slide plate 6, and the upper end of the guide shaft 9 is connected to the cylinder. Alternatively, the drive mechanism can use an electric push rod or a hydraulic cylinder instead of the cylinder, as long as it can provide vertical driving force. The guide shaft 9 and guide sleeve 8 can also be replaced with linear guides and sliders, or other structures that can achieve linear guidance.

[0043] In use, first move frame 2 (7) above frame 1 (1). At this time, the positioning hook 2 is in an unloaded state, and its lower end can be inserted into the notch of frame 1 (1). The cylinder drives the guide shaft 9 to move vertically upward, causing the slide plate 6 to move upward and push the positioning hook 2 to rotate around the support pin 4. At this time, the lower end of the positioning hook 2 will hook onto frame 1 (1), achieving locking with frame 1 (1), thus completing the fixation of frame 1 (1) and frame 2 (7). When unlocking is required, the cylinder drives the guide shaft 9 to move downward, the slide plate 6 disengages from the positioning hook 2, and the positioning hook 2 disengages from frame 1 (1) under its own gravity, thus unlocking frame 1 (1) and frame 2 (7). The entire mechanism has a simple structure, is easy to operate, and can effectively achieve the fixation and disengagement of frame 1 (1) and frame 2 (7).

[0044] In this embodiment, a pad 3 is detachably installed on the frame 1. This pad 3 is precisely positioned at the engagement point between the positioning hook 2 and the frame 1. By increasing or decreasing the number of pads 3, the mating clearance between the positioning hook 2 and the pad 3 can be flexibly adjusted. This is to prevent the positioning hook 2 from jamming during operation and to ensure smooth operation of the mechanism. Generally, this clearance should be controlled within 1.5 mm. In addition, pads 3 can also be made of different thicknesses to more precisely meet the clearance adjustment requirements.

[0045] In this embodiment, the slide plate 6 is an N-type slide plate, with both ends extending outward to form hooks 61. The positioning and fixing hook 2 is designed to work in conjunction with this, with hook 21 at the upper end and hook 32 at the lower end. When the drive mechanism moves the slide plate 6 upward, hook 61 engages precisely with hook 21. As the slide plate 6 continues to move upward, it causes the positioning and fixing hook 2 to rotate around the support pin 4. Finally, hook 32 engages with the pad 3, achieving a secure lock.

[0046] Furthermore, to improve the structural stability and positioning accuracy of the entire mechanical locking mechanism, a boss 11 is specially provided on the frame 1. Correspondingly, a groove 62 is carefully designed in the middle of the slide plate 6 to avoid the boss 11. When the slide plate 6 moves vertically under the action of the drive mechanism, the boss 11 is prevented from colliding with the slide plate 6.

[0047] A vertical channel 112 is provided in the middle of the boss 11. At the same time, a positioning post 5 is installed on the second frame 7, which can be inserted into the vertical channel 112. With this design, when the relative positions of the first frame 1 and the second frame 7 are determined, the cooperation between the positioning post 5 and the vertical channel 112 can achieve precise positioning, further enhancing the stability of the connection.

[0048] To facilitate the smooth entry of the positioning post 5 into the vertical channel 112, a guide ramp 111 is provided at the upper opening of the vertical channel 112, and a guide ramp is designed at the lower end of the positioning post 5. The guide ramp 111 and the guide ramp work together to guide the positioning post 5 as it falls into the vertical channel 112, preventing jamming or collisions and making the entire connection process smoother and more reliable.

[0049] The mechanical fixing and locking mechanism provided by this utility model is extremely easy to operate. Simply by driving the slide plate 6 up and down via the drive mechanism, the positioning and fixing hook 2 can switch between locked and disengaged states with the frame 1, thus efficiently completing the fixing and separation of the frame 1 and the frame 2. The overall structure of this mechanism is simple, eliminating complex and redundant designs. Furthermore, this mechanism has fewer components and clear connections, making both initial installation and subsequent maintenance very convenient and reducing operating costs.
