Description

Technical Field

[0001] This utility model relates to the field of warp knitting machine technology for mesh bags, and in particular to a cam transmission structure based on a warp knitting machine for mesh bags. Background Technology

[0002] The cam drive structure of the mesh bag warp knitting machine is one of its core transmission systems. It is mainly used to drive the coil forming mechanism and the comb bar traverse mechanism to achieve complex motion patterns.

[0003] Due to the special nature of the mesh bag manufacturing process, warp knitting machines need to change the cam drive configuration at specific positions during actual application to achieve the purpose of process switching. However, some traditional mechanical cam structures cannot meet the requirements. They need to use mechanical chain blocks to engage the secondary cam at specific positions. However, mechanical chain blocks have the disadvantages of complex operation and cumbersome process changes. Therefore, there is an urgent need for a cam transmission structure based on mesh bag warp knitting machines. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cam transmission structure based on a mesh bag warp knitting machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cam transmission structure based on a mesh bag warp knitting machine includes a transmission frame. A main cam is mounted on the upper part of the transmission frame via a roller. The main cam is connected to the combing mechanism of the warp knitting machine. A cam switching transmission mechanism is mounted on one side below the main cam. One end of the cam switching transmission mechanism is connected to the combing mechanism of the warp knitting machine, and the other end is provided with a secondary cam. When the secondary cam rotates, the tip of the secondary cam contacts the cam switching transmission mechanism.

[0007] Furthermore, in a preferred configuration, the main cam plate is driven and connected to the main shaft of the warp knitting machine via a mechanical sprocket transmission mechanism.

[0008] Furthermore, in a preferred configuration, the cam-switching transmission mechanism and the auxiliary cam are mounted in the middle of the transmission frame.

[0009] In addition, a preferred structure is that a drive motor is installed on one side of the transmission frame, and the output end of the drive motor drives a secondary cam plate.

[0010] Furthermore, a preferred configuration is that, under natural conditions, there is no mechanical contact between the secondary cam plate and the cam plate switching transmission mechanism.

[0011] Furthermore, in a preferred configuration, when the main cam plate rotates, the tip of the main cam plate makes contact with the combing mechanism.

[0012] The beneficial effects of this utility model are as follows:

[0013] In this invention, the main cam plate is linked to the main shaft of the warp knitting machine and the number of rotations is monitored by the main shaft encoder. When the preset number of rotations of the main shaft is reached, the drive motor drives the auxiliary cam plate to rotate synchronously with the main cam. By utilizing the transmission characteristics of the switching transmission mechanism between the auxiliary cam plate and the cam plate, the function of the main cam is replaced at specific process nodes, realizing dynamic process switching and improving work efficiency.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figure 1-2 A cam transmission structure based on a mesh bag warp knitting machine includes a transmission frame 1. A main cam plate 2 is mounted on the upper part of the transmission frame 1 via a roller. The main cam plate 2 is connected to the combing mechanism of the warp knitting machine. A cam plate switching transmission mechanism 5 is mounted on one side below the main cam plate 2. One end of the cam plate switching transmission mechanism 5 is connected to the combing mechanism of the warp knitting machine, and the other end is provided with a secondary cam plate 4. When the secondary cam plate 4 rotates, the tip of the secondary cam plate 4 contacts the cam plate switching transmission mechanism 5.

[0019] The main cam plate 2 is driven and connected to the main shaft of the warp knitting machine through a mechanical sprocket transmission mechanism.

[0020] The mechanical sprocket drive mechanism, specifically a mechanical device that transmits torque and rotational motion through chains and sprockets, is a conventional setup in this field and will not be explained further.

[0021] A spindle encoder is installed on the main spindle of the warp knitting machine to monitor the spindle's rotation status.

[0022] The cam plate switching transmission mechanism 5 and the auxiliary cam plate 4 are installed in the middle of the transmission frame 1.

[0023] A drive motor 3 is installed on one side of the transmission frame 1, and the output end of the drive motor 3 is connected to a secondary cam plate 4.

[0024] Under normal conditions, there is no mechanical contact between the secondary cam plate 4 and the cam plate switching transmission mechanism 5.

[0025] When the main cam plate 2 rotates, the tip of the main cam plate 2 makes contact with the combing mechanism.

[0026] In this embodiment, after the main shaft of the mesh bag warp knitting machine starts to rotate, the main shaft encoder starts to calculate the number of rotations of the main shaft, and the main shaft of the warp knitting machine drives the main cam plate 2 to rotate through the mechanical sprocket transmission mechanism. During the rotation, the cam tip performs cam contact transmission to the guide bar transverse movement mechanism to control the guide bar transverse movement mechanism to perform transverse movement, thereby realizing the basic knitting process. The specific operating principle of the guide bar transverse movement mechanism is common knowledge to those skilled in the art and will not be explained further.

[0027] When the warp knitting machine spindle drives the main cam plate 2 to rotate to the corresponding number of revolutions, the encoder synchronously monitors and identifies it. When the warp knitting machine spindle rotates to the set number of revolutions for the secondary cam plate 4 to intervene, the encoder excites the drive motor 3 to start moving, thereby driving the secondary cam plate 4 to rotate synchronously with the main cam plate 2.

[0028] The auxiliary cam plate 4 moves synchronously with the main cam plate 2. During the rotation of the auxiliary cam plate 4, its tip contacts the cam plate switching transmission mechanism 5. The cam plate switching transmission mechanism 5 is pushed by the cam and makes transmission contact with the warp knitting machine comb bar traverse mechanism, disconnecting the corresponding process position of the warp knitting machine comb bar traverse mechanism and replacing the corresponding process point of the main cam plate 2. This continues until the end of this cycle, when the drive motor stops moving. When the next set number of rotations is reached, the auxiliary cam plate 4 will re-engage.

[0029] It is worth noting that the cam drive structure is integrated inside the mesh bag warp knitting machine, and its specific operating principle is existing technology. Anything not explained in detail above is common knowledge to those skilled in the art and will not be explained further.

[0030] In a mesh bag warp knitting machine, the cam position is associated with different process points and weaving positions, which is easy to understand intuitively and will not be explained further.

[0031] In this process, after the main shaft rotates a certain number of revolutions, the main cam plate 2 is driven to rotate one revolution by the mechanical sprocket transmission mechanism. Specifically, depending on the actual production and processing requirements, those skilled in the art can adjust the transmission configuration to achieve different rotation ratios. This is a routine operation in the field and is easy to understand intuitively, so it will not be explained further.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
