Abstract

The utility model discloses an auxiliary penetration device for material feeding through pinch rollers. A plate-shaped material feeding element which can be driven by a pneumatic cylinder to move forward and backward is arranged on the material feeding side of the pinch rollers for feeding bag materials, an air blowing unit which is in a tubular shape is arranged on the material feeding element, and air blowing holes are formed in the surface of the air blowing unit. When the bag materials need to penetrate through a gap formed between the pinch rollers, a user just needs to place the bag materials at the front end of the material feeding element, then the pneumatic cylinder is started to drive the material feeding element to stretch forward and enable the front end of the material feeding element to reach a position next to a material feeding port of the pinch rollers, and at the same time, the pinch rollers are started to rotate, besides that the friction between the pinch rollers and the bag materials can feed the bag materials into the pinch rollers, the air blowing unit can play an auxiliary feeding role by blowing the bag materials, the bag materials are enabled to be clamped in the pinch rollers more easily, and therefore the user does not need to feed the materials with hands at all, and the operational safety is improved accordingly.

Description

The auxiliary device that penetrates of pinch roller pan feeding

Technical field

The utility model relates to see through and near the feeding mouth of pinch roller, be provided with the servicing unit that can head into Bag Material, allow the operator wear material with hand again, and then avoid hand that the anxiety that is crushed occurs.

Background technology

Polybag production is the purposes Bag Making Machine that adopts full-automatic multi-functional, the packaging bag that can produce the multi-configuration item people's livelihood or industrial product, for example: soft handgrip bag, perforation handbag, plastic bag ... etc.The control core of Bag Making Machine uses the program-controlled device of advanced microprocessor PLC even uses servo-drive system, not only allows the speed of cutting envelope rapider, and blank bag or the accurate positioning of printing electric eye, error are few.

Simultaneously, whole bag process mainly is divided into cutter lifting, location, three parts of sealing, wherein sealing cutter is through driving cutter lifting and the sealing action that circulates after slowing down by main motor, then see through servo-drive system drive pinch roller and carry out conveying and the location of predetermined length, and then carry out again the operation of involution and cut-out.

In addition, at the beginning of the Bag Making Machine start, or answer a pager's call when wearing material, the rotating speed that pinches except pinch roller can not be too fast, finger position when wearing material, can not pinch in the stub bar position excessively near apart from pinch roller, otherwise the draw that as easy as rolling off a log generation is moved because of Bag Material, cause finger to be sandwiched between the pinch roller, the red and swollen bruise of the lighter, decortication, severe one possibility fingers deformed or fracture, and this situation not only betides on the Bag Making Machine, such as the pinch roller of bag blowing machine, the pinch roller of printing machine, and other has the equipment of identical pinch roller etc., and chance and the doubt of high generation are arranged.

The utility model content

Edge is, in order to improve aforementioned existing Bag Making Machine or other has the equipment of identical pinch roller, when wearing material, the finger that happens occasionally sandwiches and injured danger, the utility model namely provides one in pinch roller pan feeding side, be provided with that its front end can enter the material folding mouth place that is in close proximity to pinch roller and with the feeding element of the material feeding wanting to pinch, and then the event of avoiding crushing with hand fed occurs.

The technical scheme that its technical problem that solves the utility model adopts is: be near pinch roller pan feeding side, establish one and driven and make its front end can be in close proximity to the feeding element at material folding mouth place.

In the such scheme, this feeding element is to be tabular.

In the such scheme, termination is established the pneumatic cylinder of its advance and retreat of driving behind this feeding element.

In the such scheme, has an insufflation unit that blows out strong gas on this feeding element.

In the such scheme, this insufflation unit is the pipe fitting that its surface axially offers a plurality of gas holes.

In the such scheme, this insufflation unit is directly to be formed at feeding element front end and its outboard end is laid with the hollow bulb of a plurality of gas holes.

The beneficial effects of the utility model are, see through near the feeding mouth of pinch roller that above-mentioned feeding element heads into Bag Material rotation, and when the feeding element is return, adding insufflation unit blows Bag Material, make Bag Material be able to more can enter the feeding mouth place of pinch roller, and then through the friction between pinch roller and the Bag Material, Bag Material can be sandwiched in the pinch roller easily, and then avoid the operator to wear the danger danger of expecting and meeting accident with hand.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is auxiliary side-looking and the local enlarged diagram thereof that penetrates of the utility model.

Fig. 2 is the auxiliary preparation schematic diagram that penetrates before device is worn material of the utility model.

Fig. 3 is the auxiliary action schematic diagram one that penetrates of the utility model.

Fig. 4 is the auxiliary action schematic diagram two that penetrates of the utility model.

Fig. 5 is another embodiment schematic diagram of the utility model feeding element.

Among the figure:

1. pinch roller, 2. bearing, 3. pneumatic cylinder,

4. feeding element, 5. insufflation unit, 50. gas holes.

The specific embodiment

See also shown in Fig. 1,2, take Bag Making Machine as example, establish a fixing bearing 2 in the pan feeding side of pinch roller 1, and at bearing 2 lockings one pneumatic cylinder 3, and make the terminal locking of the operating bar one feeding element 4 of pneumatic cylinder 3, and this feeding element 4 is flat elements, and makes again this feeding element 4 be provided with an insufflation unit 5, and this insufflation unit 5 is the pipe fittings that axially are laid with a plurality of gas holes 50 for its surface.

So situation of its action, see also Fig. 2, shown in Figure 3, when wanting to wear material, as long as Bag Material is directly striden the front end place that is placed on feeding element 4, then start Bag Making Machine and make pinch roller 1 rotate, while pneumatic cylinder 3 can order about feeding element 4 and protract, allow the front end of feeding element 4 be in close proximity to the material folding mouth place of pinch roller 4, make to see through friction effect between pinch roller 1 and the Bag Material, make Bag Material be sandwiched in the pinch roller 1, and as shown in Figure 4, namely when feeding element 4 is shunk back, also can make insufflation unit 5 blow out strong air-flow, auxiliary Bag Material more feeds in the pinch roller 1, and the success rate of material folding can more be improved; Also or, above-mentioned feeding element 4 or and the start of insufflation unit 5, repetitious execution, the probability that makes equally Bag Material be sandwiched is more to promote again, makes and can avoid wearing the failed generation of material.

Secondly, above-mentioned insufflation unit 5 also is formed directly on the feeding element 4, namely as shown in Figure 5, the front end of this feeding element 4 namely forms the insufflation unit 5 of a thin shape hollow bulb, and equally axially offer a plurality of gas holes 50 at the lateral border of hollow bulb, and then after making pressure-air import, can blow out strong air-flow by each gas hole 50, make and also can assist Bag Material more easily to be sandwiched in the pinch roller.
