Background

Blow molding is a process for making hollow thermoplastic articles. Widely known blow-molded objects are bottles, drums, cans, cases and all containers for packaging food, beverages, cosmetics, pharmaceuticals and daily necessities. Large blow-molded containers are commonly used for packaging of chemical products, lubricants, and bulk materials. Other blow molded articles are balls, bellows, and toys.

Taking plastic bottles as an example, the plastic bottles can be blow molded by a blow molding machine, and some manufacturers need to synchronously complete labeling of the bottles in the molding process, especially for some bottle products such as beverage bottles, pesticide bottles, and the like. For such products, one of the common operation flows at present is roughly: before blowing, the labeler sends label paper to be attached to a blowing mold, and the inner wall of the blowing mold is provided with air holes which adsorb the label paper on the inner wall of the blowing mold; then, the extruder melts and plastifies the resin to extrude a tubular parison, and then the parison is placed in a blow molding die, is blown up by compressed air, and is cooled and shaped to obtain a bottle body with the same shape as the die; in the process of bottle bloated, the gas pocket loosens the label paper, and the bottle contacts gradually and extrudes the label paper, and finally the two adhesion is integrative.

The above working method has the following defects: since the labels are relatively soft in paper, they often wrinkle when they are fed into the blow mold; so, after the blowing is accomplished, the label paper on bottle surface is also not smooth enough naturally, appears the condition that pattern and typeface overlap even, not only pleasing to the eye inadequately, causes the product to scrap easily moreover.

Meanwhile, the base 1 is also provided with a longitudinal driving component 5 for driving the sliding seat 3 to move; specifically, the longitudinal driving assembly 5 includes a longitudinal driving screw 51 horizontally erected on the base 1 and a longitudinal driving motor 52 fixedly arranged on one side of the base 1 in the length direction, the longitudinal driving screw 51 horizontally penetrates through the bottom of the sliding seat 3 in a threaded manner, and one end of the longitudinal driving screw is coaxially fixed with an output shaft of the longitudinal driving motor 52.

The label feeding support arms are horizontally erected on the sliding seat 3, two label feeding support arms can be arranged in parallel at intervals along the width direction of the base 1, and the two label feeding support arms are symmetrically arranged in the width direction of the base 1. Taking any one of the label sending support arms as an example, the label sending support arm comprises a connecting section 61 for connecting the sliding seat 3 and a rotating section 62 coaxially arranged on one side of the connecting section 61 far away from the sliding seat 3; the connecting section 61 is horizontally arranged on the sliding seat 3 in a sliding manner through a guide rail, and the sliding direction of the connecting section is parallel to the width direction of the base 1; one side of the rotating section 62 close to the sliding seat 3 horizontally penetrates through the connecting section 61, and forms a rotating fit with the connecting section 61 through a shaft sleeve, and a rotating driving assembly for driving the rotating section 62 to rotate is arranged on the connecting section 61. Specifically, this rotation driving assembly is including fixed setting in the rotation driving motor 7 at linkage segment 61 top, and rotation driving motor 7's output shaft passes through reduction gear and belt drive mechanism and rotates the one end transmission connection that section 62 wore out linkage segment 61.

The sliding seat 3 is also provided with a transverse driving component 8, and the transverse driving component 8 can drive the two marking support arms 6 to synchronously move. Specifically, the transverse driving assembly 8 comprises a bidirectional screw rod 81 arranged on the upper side of the sliding seat 3 through a bearing horizontal rotating frame 11, and the bidirectional screw rod 81 is horizontally threaded through the two connecting sections 61; the connecting section 61 is respectively in threaded connection with the two connecting sections 61 through threads with opposite screwing directions at two ends. Meanwhile, a transverse driving motor 82 is fixedly arranged on one side of the sliding seat 3, and an output shaft of the transverse driving motor 82 is in transmission connection with one end of a bidirectional screw rod 81 through a speed reducer.

The suction member may be a label taking suction cup 4, and the label taking suction cup 4 is fixed to one side of the rotating section 62. Moreover, on the two mark taking support arms 6, the two mark taking suckers 4 are symmetrically arranged along the width direction of the base 1.

Referring to fig. 2, the label library 2 is mainly used for storing spare label paper; in order to work together with the two label feeding support arms, the label library 2 can be respectively provided with one group at two sides of the base 1 in the width direction; thus, the two label taking support arms 6 are both just positioned between the two label libraries 2. Specifically, this mark storehouse 2 is fixed with a plurality of spacing pin 22 including fixed support 21 that sets up in base 1 upside on the fixed support 21, and each spacing pin 22 encloses into a closed area that is used for depositing label paper in batches, and the specific shape of this closed area can be adjusted according to the shape of label paper. A stop block 221 is formed at one end of the limit stop lever 22 close to the middle part of the base 1, and a back plate 23 is vertically fixed on the fixed support 21; in actual work, the edge part of the label paper close to the middle part of the base 1 is abutted with the stop block 221, and the side of the label paper departing from the middle part of the base 1 is abutted with the back plate 23; the stoppers 221 together define an opening for the label-taking suction cup 4 to suck the label paper.

In the work, two get mark support arms 6 accessible each get mark sucking disc 4 and adsorb the label paper simultaneously from the mark storehouse 2 of corresponding one side to realize the synchronous subsides mark to the bottle front and back side.

In another embodiment, if the bottle body only needs to be labeled on one side, only one label-taking support arm 6 can be arranged; correspondingly, the bidirectional screw 81 can be changed into a common screw.

Referring to fig. 3, for example, in any marking arm 6, the side of the rotating section 62 facing away from the marking suction cup 4 is further provided with an elastic rolling member, which may be an elastic air bag 9, and the elastic air bag 9 may be made of rubber, and the whole of the elastic rolling member may be shaped like a football.
