DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-Figure 5 The utility model provides a technical solution: a stably movable feeding base, comprising a base body 1, a rotating wheel 2 and a mounting seat 4, a servo motor 101 is installed at one end of the base body 1, a screw rod 102 fixed to the output end of the servo motor 101 is arranged inside the base body 1, and the two ends of the screw rod 102 are connected to the two ends of the inner wall of the base body 1 through bearings, and the four corners inside the base body 1 are inserted with a guide frame 103, and the inside of the guide frame 103 is evenly spaced and clamped with steel balls 104, and the outer side of the screw rod 102 is threadedly connected with a slider 105, and the four corners of the bottom of the slider 105 roll and abut against the steel balls 104, and the top of the slider 105 is connected with two rotating wheels 2 through a central axis, and the surface of the rotating wheel 2 is connected with a pad 3 through a fastening screw 301, and the top of the pad 3 is mounted on the mounting seat 4, and a slide rail 401 is fixed to the center of the upper side of the mounting seat 4, and the slide rail 401 is an inverted isosceles trapezoidal structure.

[0025] During specific implementation, the servo motor 101 is started to drive the screw rod 102 to rotate forward and reverse, so that the screw rod 102 and the slider 105 are threadedly transmitted, so that the slider 105 slides in the base body 1, and the steel ball 104 inside the guide frame 103 rolls and fits with the four corners of the slider 105, so as to ensure that the slider 105 slides stably. When the slider 105 slides, it can drive the rotating wheel 2, the pad 3 and the mounting seat 4 on the top to follow the movement, and the slide rail 401 above the mounting seat 4 can be installed with the material conveying assembly, and then the material conveying assembly can be conveniently driven to reciprocate and convey through the feed base.

[0026] See also Figure 3-Figure 7 , an arc-shaped piece 201 is fixed on the edge between the two rotating wheels 2, and a groove 5 is provided on the top of the slider 105 to be connected with the arc-shaped piece 201; a protrusion 202 and a first latching tooth 203 are fixed on the outer peripheral side edge of the bottom of the rotating wheel 2, and a second latching tooth 204 is also fixed at an equal distance on the edge of the rotating wheel 2 close to the first latching tooth 203, and rollers 205 are installed at the bottom of the protrusion 202 and the first latching tooth 203; sliding grooves 6 are provided in parallel on both side surfaces of the top of the base body 1, and a guide bar 601 is slidably connected inside the sliding groove 6;

[0027] An adjustment rack 602 is disposed on the upper side of the guide bar 601 away from the servo motor 101 .

[0028] In a specific implementation, when the screw rod 102 drives the slider 105 and the rotating wheel 2 to move forward, the rotating wheel 2 is fitted with the upper side of the guide bar 601 through the bottom protrusion 202 and the first latching tooth 203, and at the same time, the roller 205 at the bottom of the protrusion 202 and the first latching tooth 203 is in rolling contact with the guide bar 601, so that the rotating wheel 2 has a guiding effect when moving, and can also prevent the rotating wheel 2 from flipping and swinging left and right;

[0029] When the first latching teeth 203 of the rotating wheel 2 move to mesh with the steering rack 602 at the end of the guide bar 601, the plurality of second latching teeth 204 are positively meshed with the steering rack 602 to drive the rotating wheel 2 to rotate at an angle, so that the rotating wheel 2 can drive the pad 3 and the mounting seat 4 to perform flip adjustment, thereby having an angle adjustment function when conveying materials to a specified position, and the arc-shaped member 201 between the two rotating wheels 2 has a maximum angle limiting function when the groove 5 rotates, ensuring that the angle deflection of the pad 3 and the mounting seat 4 is limited;

[0030] On the contrary, when the screw rod 102 drives the slider 105 and the rotating wheel 2 to move in the opposite direction, the second latch tooth 204 and the first latch tooth 203 will produce a reverse meshing transmission with the adjustment rack 602, which can drive the rotating wheel 2 to rotate in the opposite angle, so that the protrusion 202 and the first latch tooth 203 at the bottom of the rotating wheel 2 will fit with the upper side of the guide bar 601, ensuring that the pad 3 and the mounting seat 4 have a horizontal sliding effect when moving in the reverse direction.

[0031] See also Figure 1 and Figure 6 The surface of the base body 1 away from the servo motor 101 is rotatably connected with an adjusting screw 603, and the adjusting screw 603 is docked on the inner side of one end of the base body 1 through a rotating disk. A threaded hole is opened at one end of the guide bar 601, and one end of the adjusting screw 603 is connected to the threaded hole of the guide bar 601.

[0032] During specific implementation, by rotating the adjusting screw 603 and the threaded hole of the guide bar 601 for threaded transmission, the guide bar 601 can be driven to slide forward and reversely along the slide groove 6, which is convenient for changing the position of the adjustment rack 602, so as to control the adjustment of the flipping angle of the rotating wheel 2 when it moves to the specified position. When the adjusting screw 603 drives the adjustment rack 602 at one end of the guide bar 601 to be close to the end position of the base body 1, it can ensure that the protrusion 202 and the first tooth 203 at the bottom of the rotating wheel 2 are always in rolling contact with the guide bar 601 through the roller 205, thereby ensuring that the pad 3 and the mounting seat 4 are always in a horizontal position.

[0033] See also Figure 1 A through hole is opened in the middle of the base body 1 near the adjusting screw 603, and a metal proximity switch 7 is installed in the through hole in the middle of the base body 1.

[0034] In the specific implementation, by installing the metal proximity switch 7 in the middle through hole of the base body 1, when the slider 105 moves to the specified position, the slider 105 will be close to the sensing end of the metal proximity switch 7, so that the metal proximity switch 7 generates an induction signal, and the signal is transmitted to the matching PLC sensor, and the servo motor 101 is controlled to stop running through the PLC sensor, thereby ensuring that the operation of the servo motor 101 has the effect of stopping quickly. This is the existing technology and will not be elaborated here.

[0035] To summarize, starting the servo motor 101 drives the screw rod 102 to rotate forward and reversely, so that the screw rod 102 and the slider 105 are threadedly transmitted, so that the slider 105 slides in the base body 1, and when the slider 105 slides, it can drive the rotating wheel 2, the pad 3 and the mounting seat 4 on the top to follow the movement, and then conveniently drive the material conveying assembly to feed through the feed base.
