DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings:

[0020] Referring to the accompanying drawings: This dust-free feeding station capable of lifting, transferring materials and weighing materials online comprises a movable base 1, a column 2 arranged on the base 1, a lifting block 3 moving along the height direction of the column 2, and a lifting arm 4 arranged on the lifting block 3 and used to place a hopper, a positioning plug 41 being arranged on the lifting arm 4, a positioning slot 31 being arranged on the lifting block 3 for limiting the final assembly position of the lifting arm 4 in the lifting block 3 and combining with the positioning plug 41, a limiting block 5 exposed outside the positioning slot 31 being arranged between the positioning plug 41 and the lifting arm 4, a locking assembly 6 acting on the limiting block 5 being arranged on the end face of the lifting block 3 forming the entrance of the positioning slot 31, the locking assembly 6 does not prevent or prevents the positioning plug 41 from detaching from the positioning slot 31 when opened or closed. The principle of the utility model is that the lifting arm 4 is inserted into the positioning slot 31 by using the positioning plug block 41 to realize the combination of itself and the lifting block 3. This method is more convenient than the prior art, speeds up the assembly efficiency, and is convenient for initial installation and subsequent maintenance. After the combination, it is locked by using the locking component 6. The locking component 6 acts on the limit block 5. The limit block 5 has the same configuration as the positioning plug block 41, but its size is larger than the positioning plug block 41. This can provide a larger action surface, and the corresponding use size of the locking component 6 can also be increased, so as to provide a stronger locking strength and better structural stability. The purpose of locking is to prevent the lifting arm 4 from separating from the lifting block 3 to ensure stability during use.

[0021] The locking assembly 6 includes a first swing arm 61, a second swing arm 62, two swing connection seats 63, a locking structure 64, and a locked structure 65. The two swing connection seats 63 are symmetrically distributed on both sides of the limit block 5. The first swing arm 61 and the second swing arm 62 are arranged on the corresponding swing connection seats 63. An assembly slot 611 is arranged at the non-swing connection end of the first swing arm 61, and an assembly plug 621 combined with the assembly slot 611 is arranged at the non-swing connection end of the second swing arm 62. The locking structure 64 is arranged on the assembly plug 621, and the locked structure 65 is arranged on the first swing arm 61 to be assembled. After the slot 611 and the assembly plug 621 are combined, they are locked and matched by the locking structure 65 and the locking structure 64. The two swing arms can abut against the limit block 5 after the assembly slot 611 and the assembly plug 621 are combined, thereby producing a lateral constraint effect on the limit block 5, and after the two swing arms are combined, they are locked and matched by the locking structure 65 and the locking structure 64. The purpose of locking is to prevent the two swing arms from separating, so that the two swing arms can stably act on the limit block 5, preventing the positioning plug 41 from disengaging from the positioning slot 31 in the direction opposite to the assembly direction, thereby ensuring the stability of the combination of the lifting block 3 and the lifting arm 4.

[0022] The locked structure 65 is configured as a rod and can swing, and the locking structure 64 is configured as a buckle, that is, the rod can be coupled with or released from the buckle by swinging, and a snap fit can be produced.

[0023] The assembly slot 611 is divided into a sliding portion 6111 and an anti-slip portion 6112 along the assembly guide, and the assembly block 621 and the sliding portion 6111 have a clearance fit, and the anti-slip portion 6112 has an interference fit. This arrangement allows the portion of the assembly block 621 located in the assembly slot 611 to have a clearance fit with the sliding portion 6111, so that the assembly block 621 can slide along the assembly guide, and when the assembly block 621 slides to the anti-slip portion 6112, it is tightly fitted therewith, so that the assembly block 621 is locked in the anti-slip portion 6112 to complete the assembly connection of the two swing arms, thereby ensuring that the two swing arms can maintain the required fitting state before locking.

[0024] The matching clearance between the assembly slot 611 and the assembly plug 621 gradually decreases along the assembly guide, so that the change of the slot width is linear, making the insertion process smoother and avoiding the phenomenon of the main body being stuck during the connection and assembly.

[0025] A weighing module 7 is arranged in the lifting arm 4, and the weight of the material in the hopper can be obtained through the weighing module 7, so as to achieve accurate proportioning of different materials.

[0026] Although the present invention has been shown and described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
