The device comprises a fixed platform 100, a semicircular clamping plate 200, a clamping arm 300, a cylinder 400, a connecting rod 500, an adhesive tape 600 and a blanking pipe 700.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.

Referring to fig. 1-5, a bag holding device includes:

the fixed platform 100 is horizontally and fixedly arranged on a blanking pipe 700 of the bagging machine;

the two semicircular clamping plates 200 are positioned at the left side and the right side of the blanking pipe 700 and are horizontally arranged, one side of each semicircular clamping plate 200 is of an inwards-concave semicircular structure, the two semicircular clamping plates 200 can be mutually folded to form a circumference, and the area of the circumference formed by the mutual folding is slightly larger than the cross-sectional area of the blanking pipe 700;

more than two arm lock 300, vertically locate between fixed platform 100 and the semi-circular splint 200, arm lock 300 comprises vertical arm and horizontally portion of bending, and arm lock 300's upper end is articulated with fixed platform 100, and the lower extreme portion of bending and semi-circular splint 200 rigid coupling, arm lock 300 drive semi-circular splint 200 respectively and do the motion of opening and shutting. Specifically, arm lock 300 rotates around the pin joint, drives two semicircle splint 200 and draws close to unloading pipe 700, and semicircle splint 200 will overlap on the unloading pipe 700 outlying wrapping bag sack sticiss on unloading pipe 700 outer wall, because semicircle splint 200 can enclose the circumference when closing, can all-round clamp on the outer wall of unloading pipe 700 with the wrapping bag sack, and is sealed effectual, prevents effectively that material loss and foreign matter from introducing.
