Technical Field

[0001] The utility model belongs to the technical field of stair railing processing, in particular to an automatic sanding machine for stair railings. Background Art

[0002] Sanding and polishing are synonyms, both referring to a method of physically removing uneven, unevenly thick materials and objects that do not meet process requirements through emery cloth, grinding wheels, sandpaper, scouring pads, non-woven polishing wheels, etc., to make them smoother, flatter, and of uniform thickness. This is a method of meeting process standards and is used in various veneer production processes, standard structural parts manufacturing, toy and handicraft industries, decoration and furniture industries, floor and wall panel building materials industries, and so on.

[0003] As the name suggests, a sander is a mechanical equipment used to complete sanding work. It involves a wide range of industries and a wide variety of categories, but people in the industry generally call the ones with automatic feeding systems sanders, and the others are called belt machines, grinding wheel machines, polishing machines, etc.

[0004] In the process of stair railing processing, sanding is an indispensable step. It can smooth out the burrs and other irregularities on the stair railing to prevent harm to the human body and increase the beauty of the stair railing.

[0005] However, the existing stair railing sanding is mostly done manually, and workers need to hold the stair railing and sand it on all sides. A small number of stair railing sanding machines have appeared on the market, which also require workers to manually fix the stair railing on a rotating clamping device and then sand it with sisal sand. These methods have a low degree of automation, require a lot of manpower and time costs, and are very inconvenient to use. Utility Model Content

A gripping head 414 is also provided on the output shaft of the rotary motor 412.

[0061] In a possible embodiment, the sisal sanding assembly 5 includes a mounting frame 51, which is arranged in the frame 1. Two sisal sand cylinders 52 are symmetrically rotated in the mounting frame 51. One end of the sisal sand cylinder 52 is provided with a sisal sand rotating reduction motor 53 connected to it for transmission, which is used to drive the sisal sand cylinder 52 to rotate. A sisal sand lifting motor 54 is provided at the bottom of one end of the mounting frame 51, and a sisal sand lifting reducer 55 is provided at the bottom of the other end of the mounting frame 51. The sisal sand lifting motor 54 and the sisal sand lifting reducer 55 are connected to each other through a lifting connecting shaft 56. The output shafts of the sisal sand lifting motor 54 and the sisal sand lifting reducer 55 are both connected to each other with a screw 57, which is screwed to the mounting frame 51 for controlling the lifting and lowering of the sisal sanding assembly 5.

[0062] In a possible embodiment, both front and rear ends of the mounting frame 51 are provided with a transfer frame lifting cylinder 61 , and the output end of the transfer frame lifting cylinder 61 is provided with a transfer frame 6 , which is disposed between the two sisal sand cylinders 52 .

[0063] In one possible embodiment, the silo 2 adopts an inclined structure, and the workpieces to be processed are placed in the silo 2 in sequence and slide toward the automatic loading mechanism 3 under the action of gravity. The automatic loading mechanism 3 is a pneumatic feeding rack, and the workpieces to be processed are transported to the processing area through the automatic loading mechanism 3.

[0064] In a possible embodiment, the transfer frame 6 is arranged at the center of the two sisal sand cylinders 52, the two rotating material clamping frames 41 correspond to the vertical positions of the two sisal sand cylinders 52, and the distance between the loading port of the automatic loading mechanism 3 and the rotating material clamping frame 41 on the right is equal to the distance between the transfer frame 6 and the rotating material clamping frame 41 on the right.

[0065] In one possible implementation, the sisal sand rotation reduction motor 53 and the rotation motor 412 rotate in opposite directions.

[0066] In one possible implementation, Figure 29 As shown, the product is also provided with a shell.

[0067] By adopting the above technical solutions:

[0068] The machine utilizes centralized loading, automatic feeding by pneumatic cylinders, automatic clamping and securing by reduction motors, automatic unloading in the middle, and a servo drive to automatically shift and polish the material rack, achieving full automation. The rack is driven by a servo motor and moves along guide rails. The entire machine sands the stair railing surface.

[0069] Process flow: centralized loading - automatic feeding - first clamping and fixing - ladder railing forward rotation sanding + material rack automatic shifting - automatic blanking in the middle - second clamping and fixing - ladder railing reverse rotation sanding + material rack automatic shifting - automatic blanking.

[0070] Supplementary drawings: drawings of the rotating feed rack and the reduction motor connection structure.

[0071] Working principle, see Figure 23-28 , stair railings A, B, C, and D are arranged in the silo 2 in sequence. Since the silo 2 is an inclined structure, the stair railing D is close to the automatic feeding mechanism 3 under the action of gravity. At this time, the mobile motor 43 controls the rotating feeding frame 4 to move to the right, and the automatic feeding mechanism 3 conveys the stair railing D to the rotary clamping frame 41 on the right. At this time, the clamping head 414 on the rotating motor 412 first contacts one end of the stair railing D, and then the clamping cylinder 411 pushes the clamping bracket 413 to slide on the rotary clamping frame 41 until the clamping head 414 on the clamping bracket 413 clamps the stair railing D.

[0072] Then, the moving motor 43 controls the rotating feeding frame 4 to move leftward until the right rotating material holding frame 41 is located above the right sisal sand drum 52. At this time, the sisal sand lifting motor 54 drives the sisal sanding assembly 5 to rise via the screw 57 until the sisal sand drum 52 contacts the stair railing D. At this time, the rotating motor 412 controls the stair railing D to rotate, and the sisal sand rotating reduction motor 53 controls the sisal sand drum 52 to rotate, thereby achieving preliminary sanding of the stair railing D.

[0073] After the preliminary sanding is completed, the mobile motor 43 controls the rotating feeding frame 4 to move to the left. At this time, the height of the intermediate transfer frame 6 is adjusted by the intermediate transfer frame lifting cylinder 61 until the stair railing D is located above the intermediate transfer frame 6. The clamping cylinder 411 is controlled to release the stair railing D, and the stair railing D falls on the intermediate transfer frame 6. Then the mobile motor 43 controls the rotating feeding frame 4 to move to the right until the rotary clamping frame 41 on the left is located above the intermediate transfer frame 6. At this time, the rotary clamping frame 41 on the right is located at the loading port of the automatic loading mechanism 3. Then the rotary clamping frame 41 on the left clamps the stair railing D, and the rotary clamping frame 41 on the right clamps the stair railing C (the specific process is the same as above).

[0074] Then, the moving motor 43 controls the rotating feeding frame 4 to move to the left until the two rotating material clamping frames 41 are respectively located above the two sisal sand cylinders 52, and controls the rotating feeding frame 4 to descend. The sisal sand cylinder 52 on the left sands the stair railing D for the second time, and the sisal sand cylinder 52 on the right sands the stair railing C for the first time (the specific process is the same as above).

[0075] Finally, the moving motor 43 controls the rotating feeding rack 4 to move to the left. At this time, the height of the transfer rack 6 is adjusted by the transfer rack lifting cylinder 61 until the stair railing C is above the transfer rack 6. The material clamping cylinder 411 is controlled to release the stair railing C, and the stair railing C falls on the transfer rack 6, and the stair railing D falls onto the finished product conveyor belt.

[0076] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
