[0044] When the scissor loader is loading, the iron material is often not placed at the center of the loading table, and the eccentric placement of the iron material causes one side of the loader to bear more weight. The sliding friction between the upper end of the scissor arm and the limiting groove is large, and the unbalanced weight aggravates the wear of the sliding block and the groove on the side of the loader with more weight, which causes the contact surfaces of the sliding block and the groove on both sides of the loading table to be worn unevenly during the long operation of the scissor arm structure below, resulting in the inclination of the loading table and the inability of the plate shearing machine to stably grab the iron material.

[0047] The technical solutions of the present application and how the technical solutions solve the above technical problems will be described in detail below with specific examples. The following specific examples can be combined with each other, and the same or similar concepts or processes may not be described again in some examples. The embodiments of the present application will be described below with reference to the drawings.
[0048] Embodiment one
[0049] Figure 1 A scissor type feeding machine structure schematic diagram provided by the embodiment of the present application is shown in Figure 1 The feeding machine comprises a feeding table 100, a base 200, a scissor structure 300 and a driving mechanism 400.
[0050] At least two symmetrical scissor structures 300 are arranged between the feeding table 100 and the base 200, and at least two guide rails 500 are symmetrically arranged at the corresponding positions of the scissor structures 300 on the feeding table 100, each guide rail 500 is connected with a scissor structure 300.
[0051] The scissor structure 300 comprises a first scissor arm 310 and a second scissor arm 320, the first scissor arm 310 is rotatably connected with the second scissor arm 320, the lower ends of the first scissor arm 310 and the second scissor arm 320 are rotatably connected with the base 200, the upper end of the first scissor arm 310 is connected with a rolling member 700 through a support shaft 600, the upper end of the second scissor arm 320 is rotatably connected with the feeding table 100, and the rolling member 700 is connected with the guide rail 500.
[0052] The driving mechanism 400 is connected with the scissor structure 300, and the driving mechanism 400 is used for driving the first scissor arm 310 and the second scissor arm 320 to open and close, the first scissor arm 310 and the second scissor arm 320 drive the rolling member 700 to roll along the length direction of the guide rail 500, so that the scissor structure 300 drives the feeding table 100 to rise and fall.
[0053] As Figure 1As shown, the scissor structures 300 are arranged on both sides of the feeding table 100 respectively, and the guide rails 500 are also arranged on both sides of the feeding table 100 correspondingly, so that the rolling members 700 at the upper ends of the first scissor arms 310 can be installed on the guide rails 500. Through the rotatable connection between the lower ends of the two scissor arms and the base 200, and the rotatable connection between the upper ends of the second scissor arms 320 and the feeding table 100, and the movable mode of the rolling members 700 connected to the upper ends of the first scissor arms 310 on the guide rails 500, it can be understood that when the driving mechanism 400 drives the scissor structures 300 to open and close, the opening and closing of the two scissor arms of the scissor structure 300 can drive the lifting of the feeding table 100.
[0054] It should be noted that the scissor type feeding machine provided by the embodiment of the present application is moved along the length direction of the guide rail 500 in the rolling mode of the rolling member 700, rather than in the sliding mode of the slider along the length direction of the guide rail 500 as in the existing scissor type feeding machine. The purpose of such design is that the friction between the rolling member 700 and the guide rail 500 during the rolling process is lower than the friction of the slider sliding in the guide rail 500, so that when the iron material is placed unbalanced on the feeding table 100, the friction between the rolling member 700 and the guide rail 500 is small, and the wear of the rolling member 700 and the guide rail 500 is also small after long-term use, thereby reducing the degree of uneven wear on both sides of the feeding machine and improving the service life of the feeding machine.
[0055] Specifically, the rolling member 700 can be a roller or a bearing, and the bearing can be a ball bearing or a needle bearing. Figure 1 As shown, for example, the two rolling members 700 can be arranged in the form of clamping one guide rail 500.
[0056] As shown, Figure 1 As shown, the driving mechanism 400 can be a hydraulic driving mode, including a hydraulic cylinder 410 and a piston rod 420. The hydraulic cylinder 410 is connected to the base 200, the piston rod 420 is sleeved in the hydraulic cylinder 410, the piston rod 420 is connected to the scissor structure 300, and the hydraulic cylinder 410 is used to drive the piston rod 420 to extend and retract, so that the piston rod 420 drives the first scissor arm 310 and the second scissor arm 320 to open and close through extension and retraction. A cross bar 800 is arranged between the two scissor structures 300, the cross bar 800 connects the first scissor arms 310 of the two symmetrical scissor structures 300, and the piston rod 420 is connected to the protruding part on the cross bar 800. When the driving mechanism 400 drives the piston rod 420 to extend and retract, the piston rod 420 can drive the scissor arms of the scissor structure 300 to open and close.
[0057] In addition, Figure 2In addition to the illustrated manner, the driving mechanism 400 can also be implemented in other ways, for example, it can be an electric screw drive, that is, an electric motor is used to drive the screw nut mechanism, and the rotation of the screw drives the opening and closing of the scissor arms, thereby accurately controlling the position of the feeding table 100; a cylinder can be used as a driving device to push or pull the scissor arms through compressed air, which is suitable for application modes with lighter load and frequent action
[0058] Embodiment two
[0059] Figure 1 The rolling member and guide rail cooperation schematic provided for the embodiment of the application Figure 2 As Figure 2 illustrated, the guide rail 500 can include a track body 510, and the track body 510 is provided with a guide groove 520, the length direction of the guide groove 520 is consistent with the length direction of the guide rail 500, and the side surface of the rolling member 700 abuts against the groove surface of the guide groove 520, so that the opening and closing of the first scissor arm 310 and the second scissor arm 320 drives the rolling member 700 to roll along the length direction of the guide groove 520. It should be noted that, since the guide groove 520 provides a clear path to limit the movement direction of the rolling member 700, it ensures that the rolling member 700 can only roll along the length direction of the guide rail 500, and this limitation reduces the lateral shaking of the rolling member 700, and improves the stability and precision of the feeding table 100 during the lifting process; since the rolling member 700 is in close abutment with the groove surface of the guide groove 520, the stress is more uniform, and the wear caused by uneven stress is reduced, thereby reducing the possibility of tilting of the feeding table 100.
[0060] Optionally, the rolling member 700 is a bearing, the upper end of the first scissor arm 310 is connected to the inner cavity of the bearing through a support shaft 600, and the outer side surface of the bearing abuts against the groove surface of the guide groove 520. The bearing can be a ball bearing as Figure 2 illustrated, and can also be other forms of bearings such as needle bearings. Specifically, the rolling contact between the outer side surface of the bearing and the guide groove 520 can significantly reduce the frictional resistance, and the bearing can provide precise motion control, reducing the shaking and deviation of the rolling member 700 on the guide rail 500, and ensuring the stability and precision of the feeding table 100 during the lifting process. In addition, the bearing material is usually specially treated, has high wear resistance and fatigue resistance, can maintain a long service life under high load and high frequency working conditions, and the design of the bearing can withstand large radial and axial loads. Due to the above advantages of the bearing, Figure 3 the design as illustrated can improve the service life of the scissor type feeding machine.
[0061] Figure 2 The rolling member and guide rail cooperation schematic provided for the embodiment of the application Figure 3 As Figure 4As shown, the rolling member 700 is a spherical ball, the upper end of the first scissor arm 310 is connected with the spherical ball through the support shaft 600, and the spherical surface of the spherical ball is in abutment with the groove surface of the guide groove 520. It should be noted that, since the spherical ball can rotate freely in multiple directions, high movement flexibility is provided, and this feature allows for slight adjustment and compensation within the guide groove 520, reducing the phenomenon of jamming caused by installation errors or structural deformation; the spherical surface contact of the spherical ball can more evenly disperse the load, reducing local stress concentration, helping to reduce wear and tear, and improving the durability and service life of the scissor-type feeding machine; due to the shape characteristics of the spherical ball, it has a certain self-centering capability and can automatically adjust its position to some extent to adapt to the changes of the guide groove 520, which is beneficial to keep the feeding machine running smoothly and reduce vibration.
[0062] Embodiment Three
[0063] In this embodiment, the upper end of the first scissor arm 310 is connected with at least two oppositely arranged rolling members 700 through the support shaft 600, and the oppositely arranged rolling members 700 hold the guide rail 500, so that the opening and closing of the scissor arm drives the rolling members 700 to roll along the length direction of the guide rail 500. In this embodiment, the rolling member 700 can be a roller. The upper end of the first scissor arm 310 is rotatably connected with the roller through the support shaft 600, and the oppositely arranged rollers hold the guide rail 500, so that the opening and closing of the scissor arm drives the rollers to roll along the length direction of the guide rail 500.
[0064] Specifically, by using oppositely arranged rolling members 700 to hold the guide rail 500, the oppositely arranged rolling members 700 provide double-sided support, which can effectively prevent the rolling members 700 from moving or shaking laterally on the guide rail 500, thereby improving the stability of the feeding table 100 during lifting. By using multiple rolling members 700 to disperse the load, the carrying capacity of the feeding machine can be improved. Moreover, the way of holding the guide rail 500 by the rolling members 700 makes it easy to replace and maintain the rolling members 700.
[0065] Figure 4 Cooperation between rolling member and guide rail provided in the embodiment of the present application Figure 5 As shown in the figure, Figure 4 The guide rail 500 can be a long and flat plate member, and the oppositely arranged rollers hold the plate member. Specifically, the flat plate member is designed simply as the guide rail 500, which is easy to manufacture and install. The way of holding the plate member by oppositely arranged rollers is also relatively simple, reducing the complex mechanical structure. In actual application, a limiting device can be arranged on both sides of the guide rail 500 to prevent the rollers from disengaging from the guide rail 500.
[0066] Figure 5 Cooperation between rolling member and guide rail provided in the embodiment of the present application As shown in the figure, As shown, the guide rail 500 is provided with V-shaped slopes on both sides, and the roller side is provided with a V-shaped groove, which cooperates with the V-shaped slope to drive the rolling member 700 to roll along the length direction of the guide rail 500 when the scissor arm is opened or closed.
[0067] Specifically, the V-shaped design has good self-centering characteristics, and the V-shaped groove of the roller can automatically adjust to adapt to the V-shaped slope of the guide rail 500. This self-centering capability ensures the precise positioning of the rolling member 700 on the guide rail 500, reduces deviation and shaking, and thus can reduce the friction between the rolling member 700 and the guide rail 500. Moreover, the V-shaped design can tolerate a certain degree of deformation or irregularity of the guide rail 500, thereby improving the service life of the feeding machine.
[0068] Finally, it should be noted that: other embodiments of the utility model will be easily thought of by those skilled in the art after considering the specification and practicing the utility model disclosed herein. The utility model is intended to cover any variations, uses, or adaptations of the utility model that follow the general principles of the utility model and include common knowledge or conventional technical means in the technical field of the utility model not disclosed by the utility model, and is not limited to the precise structure described above and shown in the drawings, and various modifications and changes can be made without departing from the scope thereof. The scope of the utility model is only limited by the appended claims.
