[0002] As a common material processing equipment, the cutting machine has been widely used in many fields dominated by manufacturing. Before cutting the material, the material needs to be sent to the body of the cutting machine. In traditional technology, the staff usually manually transports the material to the preset position, which is time-consuming and labor-intensive. In addition, the staff needs to accurately align the loading position, which has low loading efficiency and affects the continuity of material processing. In order to solve this technical problem, some cutting machines are equipped with auxiliary loading equipment, which includes clamps. The clamps are used to clamp the material and send the material to the preset position. Due to the small contact area between the clamp and the material, there is a risk of unstable clamping, which affects the loading efficiency of the material. Utility Model Content

[0007] A guide structure is provided between the second cylinder body and the frame, and the guide structure guides the second cylinder body to move back and forth along with the telescopic movement of the first piston rod.

[0008] The guide structure includes at least one guide rail and slider mechanism, and the guide rail and slider mechanism includes a slider connected to the second cylinder body and a guide rail connected to the frame.

[0009] The guide structure includes two guide rail and slider mechanisms, and the two guide rail and slider mechanisms are distributed on both sides of the second cylinder body.

[0016] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0017] 1. The material loading and positioning device in the cutting machine of the present application includes a pushing structure and a stop structure respectively located on both sides of the material processing table. When the material needs to be cut and processed, the material can be pushed by the pushing structure and the material is abutted against the stop structure, so that the preliminary positioning of the material can be achieved. There is no need for the staff to pay close attention to adjust the position of the material, which greatly improves the material loading efficiency. In addition, the pushing structure is provided with a first cylinder, a second cylinder and a pushing plate. On the one hand, the pushing plate abuts against the material and pushes the material forward. Since the contact area between the pushing plate and the material is large , reducing the possibility of material movement deviation due to uneven force during the pushing process, which helps to improve the pushing accuracy; on the other hand, the second cylinder body is connected to the first piston rod, which increases the pushing stroke of the material by the pushing structure. When the size of the material to be processed is small, it avoids the phenomenon that the material cannot be pushed to the position where it abuts against the stop structure due to the small pushing stroke of the pushing structure. Moreover, according to the different pushing stroke requirements of the material, the different pushing needs of the material can be met by controlling the first piston rod, the second piston rod, or the first piston rod and the second piston rod at the same time. For example, when it is necessary to push the material for a long stroke, the first cylinder and the second cylinder can be controlled at the same time to extend the first piston rod and the second piston rod to achieve high-speed and long-stroke pushing of the material. When the material is close to the abutting position with the stop structure, the first cylinder or the second cylinder can be selected to control and the material can be finely adjusted by one of the first piston rod and the second piston rod, so as to achieve precise positioning of the material.

[0018] 2. As a preferred embodiment of the present application, a guide structure is provided between the second cylinder body and the frame, and the guide structure guides the second cylinder body to move back and forth with the telescopic movement of the first piston rod. By providing the guide structure, it is possible to guide the movement of the second cylinder body, reduce the possibility of the second cylinder body being displaced when moving with the telescopic movement of the first piston rod, thereby improving the pushing stability of the material pushing structure; in addition, the guidance of the reciprocating movement of the second cylinder body by the guide structure also helps to alleviate the supporting pressure of the first piston rod on the second cylinder body, that is, the guide structure and the first piston rod jointly bear the kinetic energy generated during the movement of the second cylinder body, which helps to improve the service life of the first piston rod.

[0019] 3. As a preferred embodiment of the present application, the second cylinder body is provided with a mounting plate, and the first piston rod is provided with a fixing block, and the fixing block is fixedly connected to the mounting plate. By providing the mounting plate and the fixing block, on the one hand, a mounting position is provided for the second cylinder body, which is convenient for the installation of the second cylinder body; on the other hand, the way in which the mounting plate and the fixing block cooperate improves the installation stability of the second cylinder body. Compared with directly connecting the second cylinder body to the first piston rod, the connection method under this embodiment increases the connection area between the second cylinder body and the first piston rod, thereby further improving the connection stability between the first piston rod and the second cylinder body, and providing a guarantee for the stable pushing of materials.

Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0041] like Figures 1 to 3As shown, a loading and positioning device of a material cutting machine, the material cutting machine includes a frame 1, a material processing table 2 for carrying materials and a crossbeam 3 across the material processing table 2 are installed on the frame 1, a cutting device 4 for cutting materials placed on the material processing table 2 is installed on the crossbeam 3, the loading and positioning device includes a pushing structure and a stopping structure, the pushing structure and the stopping structure are arranged on the frame 1 at intervals, the material processing table 2 is located between the pushing structure and the stopping structure, and the loading end 21 of the material processing table 2 is close to the pushing structure, and the unloading end 22 of the material processing table 2 is close to The stopping structure; the pushing structure includes a first cylinder 5, a second cylinder 6 and a pushing plate 7, the first cylinder 5 includes a first cylinder body 51 and a first piston rod 52, the second cylinder 6 includes a second cylinder body 61 and a second piston rod 62, the first cylinder body 51 is fixedly mounted on the frame 1, the second cylinder body 61 is connected to the first piston rod 52, the pushing plate 7 is mounted on the second piston rod 62, the first piston rod 52 and the second piston rod 62 can selectively extend one or extend together to drive the pushing plate 7 to push the material, so as to push the material from the feeding end 21 to the position against the stopping structure.

[0042] The material loading and positioning device in the cutting machine of the present application includes a pushing structure and a stop structure respectively located on both sides of the material processing table 2. When the material needs to be cut and processed, the material can be pushed by the pushing structure and the material can be abutted against the stop structure to achieve preliminary positioning of the material. There is no need for the staff to pay close attention to adjust the position of the material, which greatly improves the material loading efficiency. In addition, the pushing structure is provided with a first cylinder 5, a second cylinder 6 and a pushing plate 7. On the one hand, the pushing plate 7 abuts against the material and pushes the material forward. Since the contact area between the pushing plate 7 and the material is large, the material loading efficiency is reduced. The possibility of the material moving out of position due to uneven force during the pushing process helps to improve the pushing accuracy; on the other hand, the second cylinder body 61 is connected to the first piston rod 52, which increases the pushing stroke of the material by the pushing structure. When the size of the material to be processed is small, it avoids the phenomenon that the material cannot be pushed to the position where it abuts against the stop structure due to the small pushing stroke of the pushing structure. Moreover, according to the different pushing stroke requirements of the material, the different pushing requirements of the material can be met by controlling the first piston rod 52, the second piston rod 62, or controlling the first piston rod 52 and the second piston rod 62 at the same time. For example, when it is necessary to push the material with a large stroke, the first cylinder 5 and the second cylinder 6 can be controlled at the same time to extend the first piston rod 52 and the second piston rod 62 to achieve high-speed and large-stroke pushing of the material. When the material is close to the abutting position with the stop structure, the first cylinder 5 or the second cylinder 6 can be selected to control and make fine adjustments to the material through one of the first piston rod 52 and the second piston rod 62, so as to achieve accurate positioning of the material.

[0043] As a preferred implementation of the present application, Figure 1 , Figure 2 As shown, a guide structure is provided between the second cylinder body 61 and the frame 1, and the guide structure guides the second cylinder body 61 to move back and forth with the telescopic movement of the first piston rod 52. By providing the guide structure, the movement of the second cylinder body 61 can be guided, and the possibility of the second cylinder body 61 being offset when moving with the telescopic movement of the first piston rod 52 is reduced, thereby improving the pushing stability of the material pushing structure for the material; in addition, the guidance of the second cylinder body 61 by the guide structure for the reciprocating movement of the second cylinder body 61 also helps to relieve the supporting pressure of the first piston rod 52 on the second cylinder body 61, that is, the guide structure and the first piston rod 52 jointly bear the kinetic energy generated during the movement of the second cylinder body 61, which helps to improve the service life of the first piston rod 52.

[0044] This embodiment does not limit the structural form of the guide structure, and it can adopt any of the following embodiments:

[0045] Embodiment 1: The guide structure includes at least one guide rail pulley mechanism, and the guide rail pulley mechanism includes a pulley connected to the second cylinder 61 and a slide rail connected to the frame 1 for the pulley to move.

[0046] Implementation method 2: Figure 2 As shown, the guide structure includes at least one guide rail slider mechanism 9, and the guide rail slider mechanism 9 includes a slider connected to the second cylinder body 61 and a guide rail connected to the frame 1. By setting the guide rail slider mechanism 9, the second cylinder body 61 and the frame 1 are guided to move by the sliding cooperation between the slider and the guide rail. On the one hand, it guides the movement of the second cylinder body 61 to prevent the second cylinder body 61 from being displaced during the movement; on the other hand, it reduces the friction area of ​​the second cylinder body 61 when it moves relative to the frame 1, thereby reducing the friction resistance of the second cylinder body 61 during the movement, making the movement of the second cylinder body 61 smoother, thereby improving the pushing efficiency of the material pushing structure for materials.

[0047] As a preferred embodiment of the second implementation mode, Figure 2 As shown, the guide structure includes two guide rail slider mechanisms 9, and the two guide rail slider mechanisms 9 are distributed on both sides of the second cylinder body 61. By providing two guide rail slider mechanisms 9, the two guide rail slider mechanisms 9 can jointly guide the movement of the second cylinder body 61, further reducing the supporting pressure of the first piston rod 52 on the second cylinder body 61, and improving the movement stability of the guide rail slider mechanism 9.

[0048] As a preferred example under this embodiment, Figure 2 As shown, the loading and positioning device further includes a connecting plate 10, and the second cylinder 61 is mounted on the connecting plate 10, and the two ends of the connecting plate 10 are respectively connected to the sliders of the two guide rail slider mechanisms 9. By providing the connecting plate 10, a relatively stable installation position is provided for the second cylinder 61, which reduces the difficulty of installing the second cylinder 61 during the assembly process; in addition, the sliders of the two guide rail slider mechanisms 9 are respectively installed at the two ends of the connecting plate 10, so that the two sliders play a uniform supporting role for the connecting plate 10, reducing the possibility of the occurrence of the deviation phenomenon caused by uneven force during the movement of the connecting plate 10, which helps to improve the movement stability of the second cylinder 61, thereby improving the pushing efficiency of the material.

[0049] As a preferred implementation of the present application, Figure 2 As shown, the second cylinder body 61 is provided with a mounting plate 110, and the first piston rod 52 is provided with a fixing block, and the fixing block is fixedly connected to the mounting plate 110. By providing the mounting plate 110 and the fixing block, on the one hand, a mounting position is provided for the second cylinder body 61, which is convenient for the installation of the second cylinder body 61; on the other hand, the way in which the mounting plate 110 cooperates with the fixing block improves the installation stability of the second cylinder body 61. Compared with directly connecting the second cylinder body 61 to the first piston rod 52, the connection method under this embodiment increases the connection area between the second cylinder body 61 and the first piston rod 52, thereby further improving the connection stability between the first piston rod 52 and the second cylinder body 61, and providing a guarantee for the stable pushing of materials.

[0050] As a preferred implementation of the present application, Figure 2 As shown, the second cylinder 6 is arranged as a whole just above the first cylinder 5. Such an arrangement enables the first cylinder 5 and the second cylinder 6 to occupy a smaller lateral space of the loading and positioning device, and reserves more installation and design space for other components, which helps to optimize the structural design of the loading and positioning device; in addition, the second cylinder 6 is arranged just above the first cylinder 5, so that the projections of the first piston rod 52 and the second piston rod 62 in the vertical direction fall on the same straight line, which helps to improve the movement stability of the first piston rod 52 and the second piston rod 62.

[0051] As a preferred implementation of the present application, Figure 1 , Figure 3As shown, the stop structure includes a stop block 8, which can move up and down relative to the frame 1 to have a stop position higher than the material processing table 2 and a avoidance position lower than the material processing table 2; when the stop block 8 is located at the stop position, it can stop the material. When the material is being fed, the stop block 8 can be raised to the stop position, so as to stop the material and assist in positioning the material. When the material is cut and needs to be sent out of the cutter, the stop block 8 can be lowered to the avoidance position to allow the material to pass smoothly; in this way, the continuity of material feeding and unloading is improved.

[0052] As a preferred embodiment of this implementation, Figure 1 As shown, the stop structure includes a plurality of stop blocks 8, and the plurality of stop structures are arranged at intervals on the frame 1. By providing a plurality of stop blocks 8, the contact area between the material and the stop block 8 can be increased when the material abuts against the stop structure, so that the material can stay in a preset position more stably under the action of the stop block 8; in addition, the plurality of stop blocks 8 are arranged at intervals, and for some materials with smaller volume sizes, the probability of them passing through between two adjacent stop blocks 8 is reduced, and the stopping needs of the stop structure for materials of different volume sizes are met.

[0053] As another preferred embodiment of this embodiment, the loading positioning device further includes a third cylinder, which is installed on the frame 1 and is used to drive the stop block 8 to move up and down. By providing the third cylinder, a power source is provided for the up and down movement of the stop block 8, and the stop block 8 can be moved between the stop position and the avoidance position without manual operation, thereby improving the lifting efficiency of the stop block 8, so that the material after cutting can be quickly sent out of the cutting machine, thereby improving the continuity of the cutting work.

[0054] Anything not described in this application can be achieved by adopting or drawing on existing technologies.

[0055] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0056] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations.
