Abstract

The utility model relates to a rocker-arm clamp type box-supporting mechanism for a packing machinery carton loading device, which is composed of a rotatable and bended rocker-arm part and an automatic clamping part which is installed on the rocker-arm, the rocker-arm part is divided into a front segment and a back segment; the front end is provided with an extension spring supporting block; the back front is provided with a hanging spring screw; the front segment and the back segment are tensioned through a tension spring; the automatic part comprises a clip, a spring leaf, a supporting rod and a supporting roller. When the supporting roller supports the spring leaf, the clip can clamp tightly. The rocker-arm clamp type box-supporting mechanism can complete to prop up the carton which is put flatly to the barrel shape. The utility model has simple structure and reliable operation and is widely used for various carton loading devices.

Description

Rocking arm clamp type case erector structure

The utility model is a kind of rocking arm clamp type case erector structure that is used for the carton packing machine.Belong to the package packing machine field.It is the main portion of carton packing machine, finishes the carton of folding placing flat is strutted, and becomes the square tube shape, so that product is packed into.

Packed in cases is had many uses.The support case part of existing carton packing machine all adopts vacuum cup formula case erector structure.Promptly inhale the side that bowl holds carton with four, the carton that will roll over placing flat then pulls into the square tube shape.The deficiency of this case erector structure is: vacuum system accuracy of manufacture height, make and maintenance difficult, and can not use oil lubrication in the especially used vacuum pump body, if inhale bowl easily with the carton greasy dirt with oil, so the manufacturing of oil-free lubrication vacuum pump is difficult especially.The part of pump is low service life.Hold case skin support case because bowl is inhaled in employing again, require case skin surface necessary smooth, with anti-gas-leak.Therefore case cortex amount is required height, need special case skin.

The utility model is the problem design-calculated that exists at above-mentioned vacuum cup formula case erector structure.This rocking arm clamp type case erector structure is without vacuum system.Therefore simple in structure, easy to manufacture, and reliable.Low to the carton requirements for quality.

The utility model is achieved in that it partly partly is made up of with the automatic clamping that is contained on the rocking arm rotatable and bent rocking arm.The rocking arm part: two sections of sub rocker arm front and back, middle front and back two are intersegmental bent, an extension spring is housed on the rocking arm leading portion props up piece with the connection of Xiao's axle, and an extension spring screw is housed on the rocking arm back segment.The extension spring tension is leaned on for two sections in front and back; Automatically clamp partly: clip is contained in the front end of rocking arm leading portion, and a reed is housed on the clip, and a pole is housed on the back segment of rocking arm, and the pole front end is equipped with one and rolls, and clip is in clamped condition when withstanding reed when rolling.Reed leaves to prop up and rolls after shaking the bending of wall leading portion, and then clip is in releasing orientation.Support case operation is; At first rocking arm rotates to the case skin, make the slit a between the big baby hem of its rocking arm leading portion front end insertion case skin, be contained in a big flanging of the clamp case skin of rocking arm leading portion front end simultaneously, rocking arm is to returning counter-rotating then, a big flanging being held the case skin by clip pulls into square tube shape to the case skin, thereby reaches the purpose of support case.

Further describe technical characterictic of the present utility model below in conjunction with accompanying drawing and embodiment:

Fig. 1 is the constructional drawing of the utility model embodiment.

Fig. 2 is the first step scheme drawing that the utility model embodiment finishes the action of support case.

Fig. 3 is the second step scheme drawing that the utility model embodiment finishes the action of support case

Fig. 4 is the 3rd step scheme drawing that the utility model embodiment finishes the action of support case.

Among the figure 1, rocking arm leading portion 2, extension spring prop up piece 3, pole 4, rocking arm back segment 5, extension spring 6, roll 7, reed 8, clip

Fig. 1 is the constructional drawing of the utility model embodiment, and its structure partly is made up of with the automatic clamping part that is contained on the rocking arm rotatable and bent rocking arm.Concrete structure is seen Fig. 1, and the rocking arm part: rocking arm is made up of rocking arm leading portion (1) and rocking arm back segment (4), and the front and back section connects by Xiao's axle, and the rocking arm back segment can rotate, and the rocking arm leading portion can be the center bending with Xiao's axle.An extension spring is housed on the rocking arm leading portion (1) props up piece (2), be equipped with one and hang the spring screw on rocking arm back segment (4), extension spring (5) tension is leaned on for two sections in the front and back of rocking arm; Automatic clamping part: clip (8) is contained in the front end of rocking arm leading portion (1), one reed (7) is housed on the clip, a pole (3) is housed on rocking arm back segment (4), the pole front end is equipped with one and rolls (6), when rocking arm leading portion (1) when bending, when reed (7) being pushed down roll (6), clip (8) is in clamped condition, reed (7) is left prop up when rolling (6), then clip (8) is in releasing orientation.The process of support case running is: at first the leading portion of rocking arm (1) is in imaginary line state shown in Figure 1, begin to start rear arm back segment (4) towards A shown in Figure 1 to rotation, behind the preceding end in contact case of rocking arm leading portion (1) skin; rocking arm becomes straight gradually; make the slit a between the big baby hem of rocking arm leading portion (1) front end insertion case skin, see shown in Fig. 2 scheme drawing.Then rocking arm back segment (4) continues rotation, make rocking arm leading portion (1) along C shown in Figure 1 to bending, roll on (6) thereby reed (7) is pressed in, at this moment clip is in clamped condition, and has clamped a big flanging of case skin, sees shown in Fig. 3 scheme drawing.To revolution, clip (8) is held a big flanging of case skin to last rocking arm back segment (4), and the case skin is pulled into the square tube shape along B shown in Figure 1, finishes the action of support case, sees shown in Fig. 4 scheme drawing.Thereby realized the purpose of this utility model.

The utility model is compared with vacuum cup formula case erector structure, has the following advantages:

1, simple in structure, part processing all is general precision, make easily, Cost is low.

2, carton surfacing situation is not had specific (special) requirements, general case skin all Can use.

3, operating maintenance is convenient, and is reliable.
