Description

Technical Field

[0001] This utility model relates to the field of bag opening machine technology, and in particular to a laser bag opening machine with good stability. Background Technology

[0002] A laser pocket-opening machine is an automated device that uses laser technology to precisely cut and process clothing pockets. It is a key piece of equipment in the field of intelligent garment manufacturing. It uses a high-energy laser beam to instantly cut the fabric at high temperature, while simultaneously completing the opening, trimming, and edge treatment of the pocket. It is widely used in the pocket production process of various garments.

[0003] Currently, traditional laser bag opening machines mainly use simple mechanical pressure plates to achieve initial fixation during fabric processing. Although this can avoid errors caused by completely manual operation and achieve basic positioning effects in mass production, there is a significant distortion problem during fabric movement.

[0004] Existing equipment often employs fixed or semi-fixed fabric fixing mechanisms, using a single pressure strip to press the fabric. As the fabric moves with the equipment feed, the pressure strip's position is not adjustable and the pressing force is insufficiently uniform, making it difficult to adapt to fabrics of different thicknesses or materials. This results in uneven pressure causing wrinkles or shifting of the fabric during movement. Furthermore, existing pressing mechanisms often rely on manual adjustment. When changing to different fabric specifications, the machine must be stopped to readjust the pressure strip height and pressure. This is not only time-consuming and labor-intensive but also exacerbates fabric distortion due to adjustment errors, thus affecting the precision of laser cutting and leading to pocket size deviations or uneven edges. This severely restricts the improvement of product quality and production efficiency. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a laser bag opening machine with good stability, which aims to improve the problem in the prior art that the position of the pressure strip is not adjustable and the pressing force is not uniform, making it difficult to adapt to fabrics of different thicknesses or materials, resulting in wrinkles or displacement of the fabric due to uneven force when it moves.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a laser bag opening machine with good stability, comprising an equipment frame, a side plate fixedly connected to the top left end of the equipment frame, an mounting plate fixedly connected to the top right side of the side plate, a laser positioning mechanism provided at the top right end of the mounting plate, a fabric pressing mechanism provided at the front side of the mounting plate for preliminary positioning of the fabric, a fabric fixing mechanism provided at the top left side of the equipment frame for pressing the fabric, and an mounting frame fixedly connected to the bottom of the mounting plate, wherein an electric sewing needle is mounted at the bottom of the mounting frame;

[0007] The fabric pressing mechanism includes an electric push rod, which is fixedly connected to the top front side of the mounting plate. A shaft is fixedly connected to the front side of the mounting plate, and an adjusting arm is rotatably connected to the outside of the shaft. The output end of the electric push rod is rotatably connected to the top front side of the adjusting arm. A damping shaft is rotatably connected to the right end of the adjusting arm. A T-shaped pressure block is fixedly connected to the rear end of the damping shaft. A quick-change component is provided at the bottom of the T-shaped pressure block. A guide plate is fixedly connected to the T-shaped pressure block through the quick-change component. A pressing plate is fixedly connected to the bottom of the guide plate.

[0008] The above technical solution achieves the following: the electric push rod drives the adjusting arm to rotate around the shaft, which in turn drives the T-shaped pressure block and the pressing plate to move up and down via the damping shaft. The quick-change mechanism connects the guide plate and the pressing plate with bolts, enabling the servo electric push rod to precisely control the pressing force, the pressing plate to evenly press the fabric, and the quick-change pressing plate to adapt to fabrics of different thicknesses, thereby improving the pressing stability and processing adaptability.

[0009] As a further description of the above technical solution:

[0010] The fabric fixing mechanism includes two multi-section telescopic rods, which are respectively fixedly connected to the front and rear ends of the top left side of the equipment frame. A connecting block is fixedly connected to the right end of each of the two multi-section telescopic rods. An electric telescopic rod is fixedly connected to the top of each of the two connecting blocks. A pressing plate is fixedly connected to the top of each of the two electric telescopic rods. A cylinder is fixedly connected to the top of each of the two pressing plates. A rotating block is rotatably connected to an adjacent side of each of the two pressing plates. The output ends of the two cylinders are rotatably connected to the interior of the two rotating blocks. A pressure strip is fixedly connected to an adjacent end of each of the two rotating blocks.

[0011] The above technical solution achieves the following: by adjusting the lateral position and manually locking the multi-section telescopic rod, the electric telescopic rod drives the pressing plate to move up and down along the limiting rod via the ball screw transmission, and the cylinder drives the rotating block to make the polyurethane pressure strip swing and press the fabric. This achieves the effect of accurately adjusting the fixed position according to the width of the fabric, ensuring the straightness of the pressure strip when it is pressed down by the sliding gap between the limiting rod and the pressing plate, and the uniform pressure of the polyurethane pressure strip to prevent the fabric from moving, thus improving the accuracy of opening the bag.

[0012] As a further description of the above technical solution:

[0013] The laser positioning mechanism includes a bracket, which is fixedly connected to the top right end of the mounting plate, and a laser emitter is fixedly connected to the right end of the bracket.

[0014] The above technical solution involves rigidly fixing the laser emitter with a steel plate welded bracket, causing it to emit red light and project it at a fixed angle onto a preset area on the equipment frame. This provides a constant positioning reference for opening fabric bags, avoids shaking of the adjustable structure, reduces the impact of laser power attenuation on positioning accuracy, and improves the accuracy of the bag opening position.

[0015] As a further description of the above technical solution:

[0016] The quick-change component includes a connecting plate. Bolt 1 passes through the top left and right ends of the T-shaped pressure block. The ends of two bolts 1 are threaded to the top left and right ends of the connecting plate, respectively. Bolt 2 passes through the four corners on the front side of the connecting plate. The ends of multiple bolts 2 are threaded to the top front side of the guide plate.

[0017] The above technical solution involves fixing the connecting plate to the top of the T-shaped pressure block with bolt one, and connecting the connecting plate to the guide plate with bolt two. This enables quick disassembly and replacement of the pressing plate, adapting to the pressing requirements of different fabric materials, reducing equipment debugging time, and improving production efficiency.

[0018] As a further description of the above technical solution:

[0019] The fabric fixing mechanism also includes two limiting rods, which are fixedly connected to the top left side of the two connecting blocks respectively, and the left sides of the two pressing plates are slidably connected to the outside of the two limiting rods respectively.

[0020] The above technical solution achieves the straightness of the press plate's up-and-down movement by using the precise sliding gap between the limiting rod and the pressing plate, ensuring that the pressing strip does not wobble when it is pressed down, and allowing the pressing strips on both sides to apply pressure synchronously, thus avoiding wrinkles in the fabric due to uneven force and improving the fixing accuracy.

[0021] As a further description of the above technical solution:

[0022] Two rubber sheets are fixedly connected to the top of the equipment rack, and the tops of both rubber sheets are designed to be non-slip.

[0023] The above technical solution uses a natural rubber sheet fixed to the top of the equipment frame. The grid-like raised texture on the top increases the friction with the fabric, which prevents the fabric from slipping during processing. Combined with the laser positioning line, it keeps the fabric in a stable position and improves the accuracy of bag opening.

[0024] As a further description of the above technical solution:

[0025] A side baffle is fixedly connected to the front side of the mounting plate, and the front end of the shaft is fixedly connected to the rear side of the side baffle.

[0026] The above technical solution involves welding and fixing the front end of the shaft with a side baffle, providing rigid support for the fabric pressing mechanism. This avoids displacement of the shaft when the adjusting arm rotates, ensuring smooth pressing action and improving the operational stability of the pressing mechanism.

[0027] As a further description of the above technical solution:

[0028] Multiple support legs are fixedly connected at equal intervals on the rear side of the mounting plate, and all of the support legs adopt a hollow design.

[0029] The above technical solution utilizes hollow steel legs evenly distributed at the rear of the mounting plate, which are welded together to evenly transfer the weight of the mounting plate to the equipment frame. This achieves the effect of reducing the weight of the equipment while ensuring structural strength, ensuring the levelness of the mounting plate, and avoiding deviations caused by vibration when the electric sewing needle is working.

[0030] This utility model has the following beneficial effects:

[0031] 1. In this utility model, a laser emitter is fixed by a bracket to emit red light, which is projected onto a preset area of ​​the equipment frame at a fixed angle. An electric push rod drives an adjusting arm to rotate around a shaft, which in turn drives a pressing plate to press the fabric through a damping shaft. This achieves the effect of improving positioning accuracy by using a fixed laser positioning reference during the fabric bag opening process, precisely controlling the pressing force through a servo electric push rod, and quickly adapting to different fabrics by using quick-change components, thereby improving the stability of the bag opening operation.

[0032] 2. In this utility model, the lateral position is adjusted and manually locked by a three-stage telescopic structure of multi-section telescopic rods. The electric telescopic rod drives the pressing plate to move up and down along the limiting rod via ball screw transmission. The cylinder drives the rotating block to make the polyurethane pressure strip swing and press the fabric. This achieves the effect of accurately adjusting the fixed position according to the width of the fabric during the fabric bag opening process, ensuring the straightness of the pressure strip pressing down through the limiting rod, and using the polyurethane elastic pressure strip to apply pressure evenly to prevent the fabric from moving, thereby improving the bag opening accuracy and equipment stability.

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.

[0041] Reference Figures 1-4 An embodiment of this utility model provides a laser bag opening machine with good stability, including a frame 1, a side plate 2 fixedly connected to the top left end of the frame 1, a mounting plate 3 fixedly connected to the top right side of the side plate 2, a laser positioning mechanism 4 provided at the top right end of the mounting plate 3, a fabric pressing mechanism 5 provided at the front side of the mounting plate 3, the fabric pressing mechanism 5 is used for preliminary positioning of the fabric, a fabric fixing mechanism 6 provided at the top left side of the frame 1, the fabric fixing mechanism 6 is used for pressing the fabric, and a mounting frame 7 fixedly connected to the bottom of the mounting plate 3, with an electric sewing needle 8 installed at the bottom of the mounting frame 7;

[0042] The laser positioning mechanism 4 includes a bracket 41, which is fixedly connected to the top right end of the mounting plate 3. A laser emitter 42 is fixedly connected to the right end of the bracket 41. The fabric pressing mechanism 5 includes an electric push rod 51, which is fixedly connected to the top front side of the mounting plate 3. A shaft 52 is fixedly connected to the front side of the mounting plate 3. An adjusting arm 53 is rotatably connected to the outside of the shaft 52. The output end of the electric push rod 51 is rotatably connected to the top front end of the adjusting arm 53. A damping shaft 54 ​​is rotatably connected to the right end of the adjusting arm 53. A T-shaped pressure block 55 is fixedly connected to the rear end of the damping shaft 54. The bottom of the T-shaped pressure block 55 is provided with a quick-change component 56, which includes a connecting plate 561. Bolt 1 562 passes through the top left and right ends of the T-shaped pressure block 55. The ends of the two bolts 1 562 are threaded to the top left and right ends of the connecting plate 561, respectively. Bolt 2 563 passes through the four corners on the front side of the connecting plate 561. The ends of the multiple bolts 2 563 are threaded to the top front side of the guide plate 57. The T-shaped pressure block 55 is fixedly connected to the guide plate 57 through the quick-change component 56. A pressing plate 58 is fixedly connected to the bottom of the guide plate 57.

[0043] Specifically, the laser positioning mechanism 4 achieves precise positioning of the fabric bag opening position through the cooperation of the bracket 41 and the laser emitter 42. The bracket 41 is welded from Q235 steel plate and is fixedly connected to the top right end of the mounting plate 3 with bolts. Its structure is an integral rigid connection. The laser emitter 42 is a semiconductor laser device, fixedly installed on the right end of the bracket 41, emitting a red positioning beam with a wavelength of 650nm. Its projection direction forms a fixed angle with the top plane of the equipment frame 1, so that the positioning beam is constantly projected onto the preset fabric bag opening area on the top of the equipment frame 1, for subsequent bag opening operations. Providing a fixed position reference, the fabric pressing mechanism 5 consists of an electric push rod 51, a shaft 52, an adjusting arm 53, a damping shaft 54, a T-shaped pressure block 55, and a quick-change assembly 56. It achieves initial positioning and pressing of the fabric. The electric push rod 51 is fixed to the top front side of the mounting plate 3, and integrates a ball screw drive structure, achieving a stroke accuracy of ±0.2mm and providing a stable thrust of 200N. The shaft 52 is fixedly connected to the front side of the mounting plate 3, and the adjusting arm 53 is rotatably connected to the outside of the shaft 52 via a bearing. Its front top end is rotatably connected to the output end of the electric push rod 51. When the electric actuator 51 extends or retracts, it drives the adjusting arm 53 to rotate around the shaft 52, thereby causing the damping shaft 54 ​​and the T-shaped pressure block 55 at the right end to move up and down. The damping shaft 54 ​​uses a copper bearing to suppress the swaying of the adjusting arm 53. In the quick-change assembly 56 at the bottom of the T-shaped pressure block 55, the connecting plate 561 is fixedly connected to the top of the T-shaped pressure block 55 by two M6 stainless steel bolts 562, and the front side is connected to the guide plate 57 by four bolts 563. The pressing plate 58 fixed at the bottom of the guide plate 57 is made of 45 steel with a hardness of HRC40. When the drive adjustment arm 53 rotates, the T-shaped pressure block 55 descends with the damping shaft 54, and the pressing plate 58 contacts the fabric and applies pressure. The stroke control of the servo electric push rod 51 keeps the pressing force stable within the range of 150-200N. The bolt connection design of the quick-change component 56 allows for quick disassembly and replacement of the pressing plate 58. Through the fixed installation of the laser positioning mechanism 4 for precise positioning and the stable pressing of the fabric pressing mechanism 5, the fabric positioning is completed with a fixed benchmark during the fabric bag opening process, thereby improving the accuracy of the bag opening operation and the stability of the equipment operation.

[0044] Reference Figure 1 , Figure 2 and Figure 5The fabric fixing mechanism 6 includes two multi-section telescopic rods 61, which are fixedly connected to the front and rear ends of the top left side of the equipment frame 1, respectively. The right ends of the two multi-section telescopic rods 61 are fixedly connected to the connecting blocks 62, the tops of the two connecting blocks 62 are fixedly connected to the electric telescopic rods 63, the tops of the two electric telescopic rods 63 are fixedly connected to the pressing plates 64, the tops of the two pressing plates 64 are fixedly connected to the cylinders 65, the adjacent sides of the two pressing plates 64 are rotatably connected to the rotating blocks 66, the output ends of the two cylinders 65 are rotatably connected to the inside of the two rotating blocks 66, and the adjacent ends of the two rotating blocks 66 are fixedly connected to the pressure strips 67. The fabric fixing mechanism 6 also includes two limiting rods 68, which are fixedly connected to the top left side of the two connecting blocks 62, and the left sides of the two pressing plates 64 are slidably connected to the outside of the two limiting rods 68.

[0045] Specifically, two multi-section telescopic rods 61 are fixedly connected to the front and rear ends of the top left side of the equipment frame 1, respectively. They are made of aluminum alloy and have a three-stage telescopic structure with a total telescopic stroke of 150mm. The lateral position can be adjusted according to the fabric size. The right end of the multi-section telescopic rod 61 is fixedly connected to a connecting block 62, which is welded from Q235 steel plate. An electric telescopic rod 63 is fixed at the top, and the top of the electric telescopic rod 63 is fixedly connected to a pressing plate 64. The left side of the pressing plate 64 is slidably connected to the outside of the limiting rod 68. The two limiting rods 68 are respectively fixed to... On the top left side of the connecting block 62, the sliding gap between the limiting rod 68 and the pressing plate 64 is 0.2mm to ensure the straightness of the pressing plate 64 when it moves up and down. The cylinder 65 fixed on the top of the pressing plate 64 is a compact pneumatic cylinder 65, and its output end is rotatably connected inside the rotating block 66. The rotating block 66 and the pressing plate 64 are rotatably connected by bearings. A pressure strip 67 is fixed at one adjacent end. The pressure strip 67 is made of polyurethane elastic material and has anti-slip texture on the surface to prevent the fabric from slipping when pressing. When the electric telescopic rod 63 is started, it drives the pressing plate 64 through the ball screw drive. The pressure plate 64 moves up and down along the limiting rod 68 to adjust the height of the pressure strip 67. After the cylinder 65 is vented, the piston rod extends or retracts, driving the rotating block 66 to rotate around the rotating axis of the pressing plate 64, causing the pressure strip 67 to swing downwards or upwards. When the pressure strip 67 contacts the fabric, the elastic deformation of the polyurethane material can adapt to the undulations of the fabric surface. The stable pressure provided by the cylinder 65 presses the fabric tightly onto the equipment frame 1. The three-stage telescopic structure of the multi-section telescopic rod 61 can be locked by a manual knob to adapt to the fixing needs of fabrics of different widths. The limiting rod 68 and the pressing plate 64... Precise fit clearance ensures no wobbling when the pressure strip 67 is pressed down, guaranteeing the accuracy of the fabric's fixed position. The precise stroke control of the servo electric telescopic rod 63 allows the pressure strips 67 on both sides to be pressed down synchronously, preventing wrinkles in the fabric due to uneven force. By adjusting the position of the multi-section telescopic rod 61 of the fabric fixing mechanism 6, controlling the height of the electric telescopic rod 63, and driving the pressure strip 67 to press down with the cylinder 65, stable fixing of fabrics of different sizes is achieved during the fabric bag opening process, preventing fabric movement from affecting the bag opening accuracy and improving the stability and reliability of the equipment.

[0046] Reference Figure 1 and Figure 2 Two rubber sheets 9 are fixedly connected to the top of the equipment frame 1. The top of the two rubber sheets 9 is designed to be non-slip. A side baffle 10 is fixedly connected to the front side of the mounting plate 3. The front end of the shaft 52 is fixedly connected to the rear side of the side baffle 10. Multiple support legs 11 are fixedly connected at equal intervals to the rear side of the mounting plate 3. All multiple support legs 11 are designed to be hollow.

[0047] Specifically, the two rubber sheets 9 fixed to the top of the equipment frame 1 are made of natural rubber, with a grid-like raised texture on the top surface to increase friction with the fabric and achieve an anti-slip function. The rubber sheets 9 are fixed to the top of the equipment frame 1 by bolts, and their elastic deformation capability can adapt to the undulations of the fabric surface to ensure that the fabric will not slip when placed. The side baffle 10 fixed to the front of the mounting plate 3 is made of Q235 steel plate with a thickness of 5mm. The front end of the shaft 52 is fixed to the rear side of the side baffle 10 by welding, forming a rigid support for the shaft 52. The side baffle 10 is... The shaft 52 of the fabric pressing mechanism 5 provides a stable mounting base, preventing displacement of the shaft 52 when the adjusting arm 53 rotates. Multiple support legs 11, which are equidistantly fixed to the rear side of the mounting plate 3, are made of Q235 square tubing and are fixed to the mounting plate 3 by welding. The hollow design reduces weight while ensuring structural strength. The bottom of the support legs 11 is welded to the top of the equipment frame 1 with a weld height of 4mm. This evenly transfers the weight of the mounting plate 3 and the laser positioning mechanism 4 and fabric pressing mechanism 5 it carries to the equipment frame 1, ensuring the levelness and stability of the mounting plate 3.

[0048] Working principle: The equipment is based on the frame 1 as its supporting structure. A side plate 2 is fixed to the top left end. A mounting plate 3 is bolted to the top right side of the side plate 2. A laser positioning mechanism 4 is located on the top right end of the mounting plate 3, a fabric pressing mechanism 5 is located on the front side, and an electric sewing needle 8 is fixed to the bottom via a mounting bracket 7. A fabric fixing mechanism 6 is located on the top left side of the frame 1, with two natural rubber sheets 9 fixed to the top. A side baffle 10 is fixed to the front side, and the mounting plate 3 is supported by hollow support legs 11 at the rear. The laser positioning mechanism 4, fabric pressing mechanism 5, fabric fixing mechanism 6, and electric sewing needle 8 are all connected to the equipment's built-in control system via wires, forming an automated processing system. The laser positioning mechanism 4 achieves precise positioning of the fabric opening position via a bracket 41 and a laser emitter 42. The bracket 41 is made of Q235 steel plate welded into an integral structure and fixed to the top right end of the mounting plate 3 with bolts. A semiconductor laser emitter 42 is fixed to its right end, emitting a red positioning beam with a wavelength of 650nm. The beam's projection direction forms a fixed angle with the top plane of the equipment rack 1, creating a constant positioning reference line on the top of the equipment rack 1. When the fabric is placed on the equipment rack 1, the operator aligns the area of ​​the fabric to be opened with this positioning line, providing a positional reference for subsequent processing. The fixed installation of the laser emitter 42 prevents the adjustable structure from shaking. Combined with the rigid support of the Q235 steel bracket 41, this ensures the stability of the positioning beam and reduces positioning deviations caused by laser power attenuation. The electric push rod 51 is fixed to the front top of the mounting plate 3, and the front end of the shaft 52 is welded... Attached to the rear side of the side baffle 10, the rear end is rotatably connected to the adjusting arm 53 via a bearing. The top front end of the adjusting arm 53 is rotatably connected to the output end of the electric push rod 51. When the electric push rod 51 extends or retracts, it drives the adjusting arm 53 to rotate around the shaft 52, causing the right-end damping shaft 54 ​​and the T-shaped pressure block 55 to move up and down. The damping shaft 54 ​​uses a copper bearing to suppress the shaking of the adjusting arm 53 and ensure smooth pressing action. The bottom of the T-shaped pressure block 55 is connected to the guide plate 57 and the pressing plate 58 via a quick-change component 56. The connecting plate 561 is fixed to the T-shaped pressure block 55 by two M6 stainless steel bolts 562, and the front side is connected to the guide plate 57 by four bolts 563. The bottom of the guide plate 57 is fixed with the pressing plate 58, which is treated with 45# steel quenching. When the pressing plate 58 contacts the fabric... At the same time, the servo electric push rod 51 evenly presses the fabric to avoid surface damage. The bolt connection design of the quick-change component 56 can adapt to the pressing needs of fabrics of different thicknesses. Two multi-section telescopic rods 61 are fixed to the front and rear ends of the left side of the top of the equipment frame 1. They are made of aluminum alloy and have an internal three-stage telescopic structure. They are locked by a manual knob and their lateral position can be adjusted according to the width of the fabric. The right end is fixed with a connecting block 62 welded from Q235 steel plate. The top of the connecting block 62 is fixed with a servo electric telescopic rod 63, the top of which is connected to the pressing plate 64. The left side of the pressing plate 64 is slidably connected to the limit rod 68. The electric telescopic rod 63 adjusts the height position of the pressure bar 67 through ball screw transmission. The top of the pressing plate 64 is fixed with a compact pneumatic cylinder 65, the output end of which is rotatably connected to the rotating block 66.The rotating block 66 and the pressing plate 64 are rotatably connected via bearings. A polyurethane pressure strip 67 is fixed to the adjacent ends. After the cylinder 65 is vented, the piston rod drives the rotating block 66 to rotate, causing the pressure strip 67 to swing downwards and press the fabric firmly onto the equipment frame 1. The elastic deformation of the polyurethane material can adapt to the undulations of the fabric surface, preventing slippage. The electric telescopic rods 63 on both sides and the cylinder 65 move synchronously through the control system to ensure that the pressure strip 67 presses down synchronously, preventing wrinkles in the fabric due to uneven force and ensuring accurate positioning. After the fabric is positioned and fixed, the electric sewing needle 8 at the bottom of the mounting plate 3 starts to sew the fabric. The electric sewing needle 8 is fixed to the bottom of the mounting plate 3 via the mounting bracket 7. Its needle movement trajectory is preset by the control system and, in conjunction with the pocket position determined by the laser positioning line, achieves precise sewing. The top of the equipment frame 1... The grid-like raised texture on the surface of the rubber sheet 9 increases the friction of the fabric, preventing it from slipping during sewing. The hollow support legs 11 on the rear side of the mounting plate 3 are welded together to evenly bear the weight of the mounting plate 3 and each mechanism, ensuring the stability of the electric sewing needle 8 during operation and preventing sewing deviations caused by vibration. The Q235 steel plate side baffle 10 on the front side of the mounting plate 3 is fixed with bolts, and the front end of the shaft 52 is welded to its rear side, providing rigid support for the fabric pressing mechanism 5 and preventing displacement of the shaft 52 when the adjusting arm 53 rotates, ensuring the stability of the pressing action. The hollow support legs 11, evenly distributed on the rear side of the mounting plate 3, are welded to the equipment frame 1, evenly transferring the weight of the laser positioning mechanism 4 and the fabric pressing mechanism 5 carried by the mounting plate 3 to the equipment frame 1, ensuring the levelness of the mounting plate 3 and preventing structural deformation due to uneven stress.
