[0011] Optionally, the adjusting member includes a bolt and a nut, and the first mounting member is connected to the bolt;

[0012] The nut is located on the side of the second mounting member opposite to the first mounting member. The bolt is threadedly connected to the nut. Tightening the nut drives the bolt to move along the first direction, so that the first mounting member can approach the second mounting member.

[0013] Optionally, the second mounting member is provided with a mounting hole, which extends through the second mounting member along the first direction, and the bolt is installed in the mounting hole.

[0014] Optionally, a gap is provided between the first mounting member and the frame along the second direction; wherein the first direction intersects the second direction.

[0015] Optionally, the transfer strip is a synchronous belt, the driving pulley is a driving pulley, the driven pulley is a driven pulley, and the synchronous belt is wound around the driving pulley and the driven pulley;

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0039] like Figures 1 to 5As shown, an embodiment of the present invention provides a door opening and closing mechanism 10, which is applied to a door opening on an opening and closing frame 20. It includes a door panel 2, a driving wheel 3, a driven wheel 4, a conveying bar 5, a driving assembly 7, and an adjusting assembly 1. The driving wheel 3 and the driven wheel 4 are arranged at intervals along a first direction on the frame 20. The conveying bar 5 is wrapped around the driving wheel 3 and the driven wheel 4. The door panel 2 is fixedly connected to the conveying bar 5.

[0040] The driving wheel 3 is connected to the output end of the drive assembly 7, and the driven wheel 4 is connected to the adjustment assembly 1. The adjustment assembly 1 can drive the driven wheel 4 to move away from the driving wheel 3 to tension the transfer bar 5.

[0041] The drive assembly 7 drives the drive wheel 3 to rotate, enabling the door panel 2 to reciprocate along a first direction. In this embodiment, the door panel 2 is slidably connected to the frame 20 along the first direction, which is the attachment direction. Figure 3 The door panel 2 is opened and closed automatically via a drive component 7 (such as a motor and reducer 72), completely eliminating the repetitive manual labor of pushing and pulling the door. This is particularly suitable for metal cutting and laser processing scenarios that require frequent door opening and closing (e.g., dozens of times per hour). When manually controlling the door panel 2, operators need to be in close contact with the equipment, posing a safety risk such as pinching injuries. In this embodiment, operators can perform related operations away from the door panel 2, effectively avoiding safety accidents such as pinching injuries caused by close contact with the door panel 2, and improving the safety of the equipment during operation.

[0042] like Figure 1 and Figure 2 As shown, in one embodiment, the adjustment component 1 includes a first mounting member 11, a second mounting member 12 and an adjustment member 13. The driven wheel 4 is arranged on the first mounting member 11, and the second mounting member 12 is arranged on the frame 20. Both the first mounting member 11 and the second mounting member 12 are connected to the adjustment member 13.

[0043] Along the first direction, the first mounting member 11 and the second mounting member 12 are arranged at intervals. The adjusting member 13 can drive the first mounting member 11 closer to the second mounting member 12, thereby driving the driven wheel 4 to move away from the driving wheel 3. In this embodiment, the adjusting member 13 (such as a threaded rod, eccentric wheel, or hydraulic cylinder) drives the first mounting member 11 closer to the second mounting member 12, causing the driven wheel 4 to move along the first direction, thereby tensioning the transfer strip 5. This ensures that it has sufficient friction and stability during transmission, preventing the door panel 2 from moving poorly or failing due to the loosening of the transfer strip 5, and ensuring the reliability of the door opening and closing.

[0044] In one embodiment, the outer peripheral surface of the adjusting member 13 is provided with a threaded section, and the second mounting member 12 is provided with a threaded hole, with the threaded section and the threaded hole being threadedly connected. In this embodiment, when the adjusting member 13 is rotated, due to the transmission characteristics of the thread, the rotational motion of the adjusting member 13 is converted into the linear motion of the first mounting member 11 along the thread direction, thereby achieving tensioning of the moving bar. At the same time, the threaded connection has good self-locking performance, which can prevent the adjusting member 13 from loosening or moving on its own due to external forces such as vibration and impact during the operation of the door opening and closing mechanism 10, ensuring the stability of the driven wheel 4 and maintaining the tension of the conveying bar 5, thereby improving the stability and reliability of the entire mechanism.

[0045] like Figure 1 and Figure 2 As shown, in one embodiment, the adjusting member 13 includes a bolt 131 and a nut 132, and the first mounting member 11 is connected to the bolt 131;

[0046] Nut 132 is located on the side of the second mounting member 12 opposite to the first mounting member 11. Bolt 131 is threadedly connected to nut 132. Tightening nut 132 drives bolt 131 to move in a first direction, allowing the first mounting member 11 to approach the second mounting member 12. In this embodiment, bolt 131 can be fixed to the first mounting member 11, or the first mounting member 11 can have mounting holes in which bolt 131 is installed (e.g., bolt 131 can pass through the mounting hole). By tightening nut 132, the movement distance of bolt 131 can be precisely controlled, thereby precisely adjusting the position of driven wheel 4, ensuring that the tension of conveying strip 5 meets the requirements, and improving the stability and reliability of door opening and closing. Meanwhile, the nut 132 is located between the head and tail of the bolt 131. During the movement of the bolt 131, the bolt head can abut against the nut 132, thereby stopping the bolt 131 and preventing it from moving excessively and causing the nut 132 to fall off, thus ensuring the stability of the adjusting component 13. Furthermore, the threaded connection between the bolt 131 and the nut 132 is typically self-locking. After adjustment, it can maintain its current position without external force and will not shift due to vibration or other external forces, ensuring a stable tension state after adjustment. Additionally, the bolt 131 and nut 132 have a simple structure, occupy little space, and are easily integrated into the existing door opening and closing mechanism 10 without significantly affecting the overall structure. This also helps improve the compactness and integration of the mechanism.

[0047] In one embodiment, the second mounting member 12 has a mounting hole that extends through the second mounting member 12 along the first direction, and the bolt 131 is installed in the mounting hole. In this embodiment, the mounting hole can be a through hole or a threaded hole. The mounting hole provides precise guidance for the bolt 131, ensuring that the bolt 131 can only move along the first direction, restricting its degrees of freedom in other directions. This allows the first mounting member 11 to accurately approach or move away from the second mounting member 12 under the drive of the bolt 131, improving the accuracy of the driven wheel 4 position adjustment and ensuring the accuracy of the tension adjustment of the transfer strip 5.

[0048] like Figure 3 and Figure 4 As shown, in one embodiment, a gap 8 is provided between the first mounting member 11 and the frame 20 along the second direction; wherein the first direction intersects the second direction. In this embodiment, the first direction is perpendicular to the second direction, and the second direction is adjacent to the frame 20. Figure 3 In the Y direction. With a gap 8 between the first mounting component 11 and the frame 20, direct contact between them can be reduced, thereby decreasing friction. This can effectively extend the service life of the first mounting component 11 and the frame 20, reduce equipment maintenance and replacement costs, and improve the economy and reliability of the equipment.

[0049] In one embodiment, the transfer bar 5 is a synchronous belt, the driving pulley 3 is a driving pulley, and the driven pulley 4 is a driven pulley, with the synchronous belt wrapped around the driving pulley and the driven pulley;

[0050] Alternatively, the conveyor bar 5 can be a chain, the driving wheel 3 a driving sprocket, and the driven wheel 4 a driven sprocket, with the chain wound around the driving and driven sprockets. In this embodiment, the synchronous belt has high transmission efficiency, reducing energy loss and improving equipment operating efficiency. The chain has strong load-bearing capacity, capable of withstanding large tensions and loads, making it particularly suitable for doors that require frequent opening and closing or bear heavy loads. Different types of moving bars can be selected according to different scenarios. For example, if the door opening and closing mechanism 10 requires high precision, low noise, and maintenance-free operation, a synchronous belt and its pulleys can be selected; if the door opening and closing mechanism 10 requires high load-bearing capacity, durability, and adaptability to complex working conditions, a chain and its sprockets can be selected.

[0051] like Figure 3 and Figure 4As shown, in one embodiment, the door opening and closing mechanism 10 further includes a connecting seat 6, which is mounted on the transfer strip 5, and the door panel 2 is connected to the connecting seat 6. In this embodiment, the connecting seat 6 serves as an intermediate connecting component, which can firmly connect the door panel 2 and the transfer strip 5 together, ensuring that the door panel 2 and the transfer strip 5 will not loosen or fall off during the door opening and closing process, thereby improving the stability of the entire opening and closing mechanism. At the same time, the connecting seat 6 makes the connection between the door panel 2 and the transfer strip 5 simpler and more standardized, reducing the complexity and errors in the installation process and improving installation efficiency.

[0052] In one embodiment, the transfer bar 5 is provided with a synchronizing tooth 51, and the connecting seat 6 is provided with a toothed groove, with the synchronizing tooth 51 engaging with the toothed groove. In this embodiment, the synchronizing tooth 51 is located on the inner side of the transfer bar 5, and the engagement of the synchronizing tooth 51 with the toothed groove ensures the stability of the connection between the connecting seat 6 and the transfer bar 5, enabling precise control of the opening and closing position of the door.

[0053] like Figure 4 and Figure 5 As shown, in one embodiment, the connecting seat 6 includes a first mounting seat 61 and a second mounting seat 62 connected together. The first mounting seat 61 is mounted on the transfer strip 5, and the second mounting seat 62 is connected to the door panel 2. In this embodiment, the design of the split connecting seat 6 makes the installation process simpler and more standardized, reduces the complexity and errors in the installation process, and improves installation efficiency.

[0054] like Figure 3 and Figure 4 As shown, in one embodiment, there are multiple connecting seats 6, which are arranged at intervals along the first direction. In this embodiment, the multiple connecting seats 6 are arranged at intervals along the first direction, which can more evenly distribute the weight of the door and the force during opening and closing, making the door more stable during opening and closing and reducing shaking and vibration.

[0055] In one embodiment, the drive component 7 is a drive motor 71, which is arranged on the frame 20, and the drive wheel 3 is connected to the output end of the drive motor 71. In this embodiment, the drive motor 71 can provide precise power output, and the control unit of the motor can realize precise control of the opening and closing speed and position of the door, thereby achieving automated operation and improving production efficiency and operational safety.

[0056] In one embodiment, the drive assembly 7 includes a drive motor 71 and a reducer 72. The reducer 72 and the drive motor 71 are arranged on the frame 20. The input end of the reducer 72 is connected to the output end of the drive motor 71, and the output end of the reducer 72 is connected to the drive wheel 3. In this embodiment, the reducer 72 can reduce the high speed of the drive motor 71 while increasing the torque, enabling the drive wheel 3 to drive the door to open and close more powerfully. At the same time, the reducer 72 can smooth the motor output, reduce the impact and vibration during the opening and closing process, and make the door run more smoothly, especially in the case of frequent opening and closing, it can effectively reduce mechanical wear.

[0057] In one embodiment, the extension direction of the output end of the drive motor 71 is the same as the extension direction of the input end of the reducer 72;

[0058] The extension direction of the input end of the reducer 72 coincides with the extension direction of the output end of the reducer 72; or, the extension direction of the input end of the reducer 72 intersects with the extension direction of the output end of the reducer 72. In this embodiment, the extension direction of the input end of the reducer 72 is perpendicular to the extension direction of the output end of the reducer 72. The coincidence of the extension directions of the input and output ends ensures a straight power transmission path, reducing energy loss during power transmission and improving the system's transmission efficiency. The intersection of the extension directions of the input and output ends allows for flexible adjustment of the relative positions of the motor and the reducer 72, adapting to different installation spaces and layout requirements. This enables a more compact layout within a limited space, improving space utilization.

[0059] According to the door opening and closing mechanism 10 provided in this embodiment of the present invention, the output end of the drive component 7 is connected to the drive wheel 3. When the drive component 7 is started, the drive wheel 3 begins to rotate. Since the transfer strip 5 is wound around the drive wheel 3 and the driven wheel 4, and the door panel 2 is fixedly connected to the transfer strip 5, the rotation of the drive wheel 3 will drive the transfer strip 5 to move along the first direction, thereby causing the door panel 2 to reciprocate along the first direction, realizing the opening and closing of the door. The driven wheel 4 is connected to the adjustment component 1. The adjustment component 1 can drive the driven wheel 4 to move away from the drive wheel 3, thereby tensioning the transfer strip 5 and ensuring that the transfer strip 5 has sufficient stability during transmission, so that the door panel 2 can move smoothly and accurately. Automatic opening and closing of the door is realized, eliminating the need for frequent manual opening and closing of the door, reducing the labor intensity of operators, and is especially suitable for machine cutting equipment that requires frequent opening and closing of doors, improving work efficiency. At the same time, operators do not need to be in close contact with the equipment to open and close the door, reducing the safety risks such as pinching injuries, ensuring the personal safety of operators, and also reducing the equipment damage that may be caused by improper manual operation.

[0060] The present invention provides a processing equipment including a frame 20 and a door opening and closing mechanism 10 as described in the above embodiment, wherein the frame 20 is provided with a door opening.

[0061] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
