AI Technical Summary
In the existing technology, the slider on side A cannot maintain stable support force during the edge wrapping process, which leads to the destruction of the integrity of side A of the product. In addition, the slider moves forward and backward inconsistently, which easily causes problems with unqualified peeling. Furthermore, the position of the cylinder is prone to change.
The first and second connecting rods are connected in a straight line at a dead point. The first and second connecting rods are driven by the third connecting rod, which provides a fixing function and exits the dead point when the slider retracts, thus avoiding product failure and ensuring that the cylinder's stroke is fixed and its position is stable.
This improved product quality stability, reduced debugging frequency, ensured the stability and consistency of the slider edge-wrapping process, and prevented product defects.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of machine tool processing technology, and in particular to a slider edge-wrapping drive device with a self-locking structure. Background Technology
[0002] Currently, in the process of edge wrapping products, existing technologies typically use a cylinder to push the A-side slider to ensure the pressure on the A-side of the product. When the reverse wrapping slider is pushed out, the A-side slider cannot provide support, and the A-side slider will retract in the opposite direction of the cylinder's push, resulting in the destruction of the integrity of the A-side of the product.
[0003] Furthermore, the A-side slider cannot guarantee consistency when moving forward and backward. Insufficient pressure on the A-side product can lead to issues such as product peeling and non-compliance. The entire production process is unstable, and prolonged production can easily cause changes in the cylinder position. Utility Model Content
[0004] To address the aforementioned issues, this utility model provides a slider edge-wrapping drive device with a self-locking structure. The device is linearly connected to the dead point formed by the first and second connecting rods. A cylinder drives the first and second connecting rods via a third connecting rod. This not only provides a fixing function for the A-side slider but also allows it to exit the dead point during the A-side slider's retraction process. This avoids the problem of the reverse-wrapping slider pushing the A-side slider back, which could lead to product malfunctions or defects. The cylinder's stroke is fixed and its position is stable, reducing the frequency of adjustments and improving product quality stability.
[0005] To achieve the above objectives, this utility model provides a slider edge-wrapping drive device with a self-locking structure, comprising: a cylinder and a transmission assembly, wherein the transmission assembly includes a first connecting rod, a second connecting rod, and a third connecting rod;
[0006] The movable end of the cylinder is hinged to one end of the third connecting rod, the fixed end of the first connecting rod is fixedly hinged to the fixed frame, the fixed end of the second connecting rod is fixedly hinged to the slider on surface A, and the other end of the third connecting rod is hinged to the movable ends of the first connecting rod and the second connecting rod.
[0007] When the slider on surface A reaches surface A of the product, the first connecting rod and the second connecting rod are connected in a straight line, and the third connecting rod is connected perpendicularly to the first connecting rod and the second connecting rod.
[0008] When the cylinder drives the third connecting rod to move, it can cause the movable ends of the first connecting rod and the second connecting rod to shift to an obtuse angle connection state, and at the same time cause the A-side slider to retract.
[0009] In the above technical solution, preferably, the first connecting rod and the second connecting rod are in a dead position when they are in a straight line connection. The first connecting rod and the second connecting rod together constitute the fixing member of the A-side slider and can exit the dead position when the A-side slider retracts.
[0010] In the above technical solution, preferably, the slider edge-wrapping drive device with a self-locking structure includes two sets of symmetrically arranged transmission components. The two sets of transmission components are respectively arranged on the upper and lower sides of the movable end of the cylinder, and the fixed ends of the two sets of second connecting rods are symmetrically connected relative to the A-side slider.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: By connecting the dead point formed by the first link and the second link in a straight line, the cylinder drives the first link and the second link through the third link, which can not only provide a fixing function for the A-side slider, but also exit the dead point during the A-side slider's retraction process, thus avoiding the problem of the reverse-wrapped slider pushing the A-side slider back, which would cause product failure or defects. The cylinder's stroke is fixed and its position is stable, which can reduce the frequency of debugging and improve the quality stability of the product. Attached Figure Description

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0016] The present invention will now be described in further detail with reference to the accompanying drawings:
[0017] like Figure 1 As shown, a slider edge-wrapping drive device with a self-locking structure provided by the present invention includes: a cylinder 4 and a transmission assembly, the transmission assembly including a first connecting rod 1, a second connecting rod 2 and a third connecting rod 3;
[0018] The movable end of cylinder 4 is hinged to one end of the third connecting rod 3, the fixed end of the first connecting rod 1 is fixedly hinged to the fixed frame, the fixed end of the second connecting rod 2 is fixedly hinged to the slider 5 on surface A, and the other end of the third connecting rod 3 is hinged to the movable ends of the first connecting rod 1 and the second connecting rod 2.
[0019] When slider 5 on surface A reaches surface A of the product, the first connecting rod 1 and the second connecting rod 2 are connected in a straight line, and the third connecting rod 3 is connected perpendicularly to the first connecting rod 1 and the second connecting rod 2.
[0020] When cylinder 4 drives the third connecting rod 3 to move, it can drive the movable ends of the first connecting rod 1 and the second connecting rod 2 to shift to an obtuse angle connection state, and at the same time drive the A-side slider 5 to retract.
[0021] In this embodiment, a self-locking structure is formed by a straight connection between the dead point of the first connecting rod 1 and the second connecting rod 2. The cylinder 4 drives the first connecting rod 1 and the second connecting rod 2 through the third connecting rod 3. This not only provides a fixing function for the A-side slider 5, but also allows the A-side slider 5 to exit the dead point during its retraction. This avoids the problem of the reverse slider 6 pushing the A-side slider 5 back, which could cause product failure or defects. The cylinder 4 has a fixed stroke and stable position, which can reduce the frequency of debugging and improve the quality stability of the product.
[0022] In the above embodiment, preferably, the first connecting rod 1 and the second connecting rod 2 are in a dead position when they are in a straight line connection. The first connecting rod 1 and the second connecting rod 2 together constitute the fixing part of the A-side slider 5, and can exit the dead position and exit the self-locking structure when the A-side slider 5 retracts.
[0023] During implementation, as the moving end of cylinder 4 drives the third link 3 to move, the third link 3 moves at an angle relative to the first link 1 and the second link 2 until it is perpendicular to the first link 1 and the second link 2. At the same time, the first link 1 and the second link 2 can move from the angle of inclination to form a straight line connection. When the straight line connection is formed, the A-side slider 5 connected to the second link 2 reaches the farthest position relative to cylinder 4, that is, the working position of the A-side slider 5. At this time, the straight-connected first link 1 and the second link 2 can also provide a support function similar to a fixing device for the A-side slider 5.
[0024] In this connected state, if the reverse slider 6 pushes the A-side slider 5 back, the first link 1 and the second link 2 can also exit the dead point state, avoiding the impact of the return action on the product, thereby improving the quality stability of the product.
[0025] In the above embodiment, preferably, the slider edge-wrapping drive device with a self-locking structure includes two sets of symmetrically arranged transmission components. The two sets of transmission components are respectively arranged on the upper and lower sides of the movable end of the cylinder 4, and the fixed ends of the two sets of second connecting rods 2 are symmetrically connected to the slider 5 on surface A.
[0026] In this embodiment, the two sets of symmetrically arranged transmission components can effectively improve the driving stability of the cylinder 4 on the A-side slider 5, and also improve the reliability of the transmission process.
[0027] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
