Detailed implementation manners

[0029] The following embodiments will describe the present invention in detail in conjunction with the drawings. In the drawings or descriptions, similar or identical parts use the same reference numerals, and in actual applications, the shapes, thicknesses, or heights of the components can be enlarged or reduced. The various embodiments listed in the present invention are only used to illustrate the present invention and are not used to limit the scope of the present invention. Any obvious modification or change made to the present invention does not depart from the spirit and scope of the present invention.

[0030] Please refer to Figures 1 to 11 , in the embodiment of the present invention, a self-transporting device for building materials includes a loading mechanism 1, a transfer mechanism 2, and a feeding mechanism 3. The loading mechanism 1 and the feeding mechanism 3 are connected through the transfer mechanism 2. In this embodiment, building boards are taken as an example for introduction. The material is first loaded through the loading mechanism 1 and then sent into the transfer mechanism 2, and then the material is sent into the feeding mechanism 3 through the transfer mechanism 2, and finally the material is transported out through the feeding mechanism 3. The material is stacked on one side of the loading mechanism 1 in the initial stage, and the entire subsequent transportation process is fully automated.

[0031] Please refer to Figures 2 to 6, the feeding mechanism 1 includes a feeding rack 101. At both ends of the feeding rack 101 facing the transfer mechanism 2, mounting racks 102 are fixed. At the bottom inside both mounting racks 102, fixing seats 104 are fixed. A feeding cylinder 115 is rotatably connected between the two fixing seats 104. At the center of the top of the two fixing seats 104, support seats 105 are fixed. Above the two support seats 105 correspondingly inside the two mounting racks 102, sliding seats 106 are slidably connected. A pressing cylinder 109 is rotatably connected between the two sliding seats 106. The pressing cylinder 109 is arranged directly above the feeding cylinder 115, and there is a gap between the two for feeding. Anti-slip structures are provided on the outer surfaces of the cylinders of the feeding cylinder 115 and the pressing cylinder 109. In this embodiment, building materials pass through the gap between the feeding cylinder 115 and the pressing cylinder 109. The pressing cylinder 109 presses against the upper side of the material, and the feeding cylinder 115 presses against the lower side of the material. Anti-slip structures are provided on the outer surfaces of both cylinders. The anti-slip structure can be an anti-slip pad or a rubber sleeve. When the feeding cylinder 115 rotates, the material is conveyed to one side through the cooperation of the clamping force between the two cylinders and the friction force on the cylinder surface; At the center of the inner walls of the two sliding seats 106, limiting slide rods 107 penetrate through slidably. Both ends of the two limiting slide rods 107 extend outside the corresponding sliding seats 106. The bottom ends of the two limiting slide rods 107 are inserted into the corresponding support seats 105 on one side. The top ends of the two limiting slide rods 107 are fixed to the mounting racks 102 on the corresponding side. Limiting springs 108 are sleeved on the upper ends of the two limiting slide rods 107. Both ends of the two limiting springs 108 are fixedly connected to the corresponding sliding seats 106 and mounting racks 102 respectively. In this embodiment, the sliding seats 106 are limited and slidably connected in the mounting racks 102 by the limiting slide rods 107. Limiting springs 108 are sleeved on the limiting slide rods 107. Under the elastic force of the springs, the sliding seats 106 will drive the pressing cylinder 109 to move downward and finally press against the upper side of the material; A transmission shaft 117 is rotatably connected to the side of the loading rack 101 away from the mounting rack 102. One end of the transmission shaft 117 extends to the outside of the loading rack 101 and a driving wheel 114 is fixed to one end of the transmission shaft 117. A driven wheel 112 is rotatably connected to the side of the loading barrel 115 on the outside of the loading rack 101. The driven wheel 112 is coaxially fixed with the loading barrel 115. The diameter of the driven wheel 112 is smaller than the diameter of the driving wheel 114. The driven wheel 112 and the driving wheel 114 are connected through a belt 113. The outside of the loading rack 101 corresponds to the transmission shaft 117. A feeding motor 103 is installed on one side, and one end of the output shaft of the feeding motor 103 is connected and fixed to one end of a transmission shaft 117. In this embodiment, the transmission shaft 117 is rotated by the feeding motor 103, and a driving wheel 114 is fixed to one end of the transmission shaft 117. The driving wheel 114 is connected to the driven wheel 112 through a belt 113. When the driving wheel 114 rotates, the driven wheel 112 rotates synchronously and drives the feeding barrel 115 to rotate to realize feeding. The radius of the driving wheel is larger than that of the driven wheel, so that the driven wheel rotates relatively faster, and the feeding barrel rotates faster, which is convenient and fast for feeding; A loading platform 111 is fixed on one side of the loading rack 101 corresponding to the loading barrel 115, and limit slides 110 are fixed at the four corners of the top of the loading platform 111. The four limit slides 110 surround and form a material slideway for stacking materials and the materials can slide up and down in the slideway. A through groove 118 is opened on one side of the bottom of the loading platform 111, and a guide rail 123 is fixed on one side of the bottom of the loading platform 111 corresponding to the through groove 118. A guide block 119 is slidably connected in the guide rail 123. The upper surface of the guide block 119 is flush with the groove surface of the through groove 118, and the guide block 119 is flush with the groove surface of the through groove 118. A stopper for pushing the material is fixed at one end of 9, a guide rod 120 is fixed at the middle position inside the guide rail 123, a guide block 119 is slidably sleeved on the guide rod 120, a guide spring 121 is sleeved at one end of the guide rod 120, and the two ends of the guide spring 121 are respectively connected and fixed to the guide block 119 and the side wall of the guide rail 123, and the material placed in the material slideway is pushed to one side and reaches the gap on one side of the upper barrel and the lower pressure barrel through the coordinated use of the guide rail 123, the guide block 119, the guide spring 121 and the stopper fixed at one end of the guide block 119; On one side below the guide block 119, a connecting rod 122 is provided. Connecting pieces 125 are provided at both ends of the connecting rod 122. The top end of the connecting rod 122 is rotatably connected to the bottom of the guide block 119 through the connecting piece 125. The bottom end of the connecting rod 122 is rotatably connected to the loading rack 101 through the connecting piece 125. A through chute is opened on the inner wall of the guide rail 123 corresponding to one side of the connecting rod 122. The top end of the connecting rod 122 and the connecting piece 125 at the top end of the connecting rod are both slidably connected in the chute. A roller 124 is rotatably connected to one side of the connecting rod 122. The roller 124 is arranged on one side of the transmission shaft 117. A cam 116 is sleeved and fixed at one end of the transmission shaft 117 corresponding to the roller 124. The cam 116 is arranged corresponding to the roller 124. When the cam 116 rotates, its convex surface will abut against the roller 124 and push the roller 124 to one side. The thickness of the cam 116 is greater than the thickness of the roller 124; In this embodiment, the materials are stacked on the loading table 111 and are slidably limited by the limiting sliding frame 110. When the loading motor 103 operates, the cam 116 rotates self - and regularly squeezes the roller 124. When the convex surface of the cam squeezes the roller, the roller moves outward and drives the connecting rod 122 to gradually move outward. The connecting rod 122 cooperates with the connecting piece 125. When the connecting rod moves, it drives the guide block 119 to move outward synchronously. At this time, the guiding spring 121 is stretched; When the concave surface of the cam contacts the roller, the roller is no longer squeezed and the connecting rod is no longer pushed. Under the action of the guiding spring 121, the guide block 119 resets inward. At this time, the stop block at one end of the guide block will abut against the material and push the material toward the side of the loading cylinder 115. The loading cylinder 115 is kept in synchronous motion with the cam 116 through a belt transmission structure. When the material is fed to one side of the loading cylinder, the self - rotation of the loading cylinder will convey the material to one side. When the loading cylinder is feeding, the guide block 119 also moves to the leftmost end. At this time, the loading of one material is completed. Subsequently, under the action of the cam, the guide block moves to the rightmost end again, repeating the above process, cycling continuously to achieve continuous loading.

[0032] Please refer to Figure 7 , the transfer mechanism 2 includes a transfer rack 201 and a transfer table fixed on the transfer rack 201. The transfer table includes a horizontally arranged first transfer table 202 and an inclined second transfer table 203. The first transfer table 202 and the second transfer table 203 are connected and fixed. The first transfer table 202 is arranged on one side close to the loading mechanism 1. One end surface of the first transfer table 202 is arranged facing the gap between the loading cylinder 115 and the pressing cylinder 109. The downward - inclined end of the second transfer table 203 is arranged on one side close to the feeding mechanism 3. To ensure smoother sliding, pulleys are arranged on the table surface of the transfer table and can be used with existing technologies.

[0033] Please refer to Figures 8 to 11The feeding mechanism 3 includes a feeding frame 301, on which a feeding platform 302 is fixed. The feeding platform 302 is two tracks symmetrically arranged front and back, with a space between the two tracks and a slide rail 303 arranged in the space. A slide rail 303 is slidably connected to a slide table 304, which is located at the lower side of the feeding platform 302. A plurality of swing seats 306 are fixed at equal intervals on the top of the slide table 304, and an L-shaped swing rod 305 is rotatably connected to the plurality of swing seats 306. A plurality of grooves 308 are evenly arranged on the inner wall of the feeding platform 302, and guide wheels 309 are rotatably connected in the plurality of grooves 308. The upper end surfaces of the plurality of guide wheels 309 extend to the outside of the corresponding grooves 308. The material is transported to one side between the two tracks of the feeding platform 302. The guide wheels 309 on the inner wall of the track can reduce the friction between the material and the track during material transportation, and the material movement will be smoother. A connecting seat 310 is fixed to one side of the bottom of the slide 304, and a through slide groove is opened on the inner wall of the slide rail 303 corresponding to one side of the connecting seat 310. The connecting seat 310 is slidably connected in the slide groove. A first crank 311 is rotatably connected to the lower side of the slide 304 through the connecting seat 310. The end of the first crank 311 away from the slide 304 is rotatably connected to the second crank 312. The end of the second crank 312 away from the first crank 311 is provided with a mounting seat 313. The mounting seat 313 is fixed to the feeding rack 301 through a bracket. The second crank 311 is rotatably connected to the feeding rack 301 through the connecting seat 310. One end of the mounting base 313 is rotatably connected to the mounting base 313, and a feeding motor 307 is installed on one side of the outer side of the mounting base 313. One end of the output shaft of the feeding motor 307 is fixedly connected to one end of the second crank 312. The second crank 312 is rotated by the feeding motor 307, and the second crank 312 cooperates with the first crank 311 to drive the first crank 311 to swing back and forth left and right. One end of the first crank 311 is rotatably connected to the slide 304. When the first crank 311 swings left and right, the slide 304 will move back and forth on the slide rail 303.

[0034] In this embodiment, when the material enters the feeding table 302, the feeding motor 307 is started, and the motor drives the second crank 312 to rotate. The second crank is rotatably connected to the first crank 311, and the first crank 311 is rotatably connected to the slide 304 through the connecting seat 310. When the second crank continues to rotate, the slide 304 will slide left and right on the slide rail 303. When the slide 304 slides to the right, the vertical upward end of the L-shaped rocker arm 305 contacts the material and rotates. The other end of the L-shaped rocker arm will tilt upward until it stabilizes and does not move. Then the slide 304 slides to the left. At this time, the vertical end of the L-shaped rocker arm will resist the material and push the material to one side. After pushing a certain distance, the slide 304 slides to the right again and repeats the above process, repeating the cycle to achieve step-by-step feeding.
