Description

Novel rubber band feeding device

Technical Field

The utility model relates to a line class feeding device especially relates to a novel rubber band feeding device.

Background

The feeding device is a device for feeding, and one type is a feeding device for conveying a belt or a wire, and particularly a feeding device for conveying a rubber band. Get into next process behind the rubber band passing feeding device, and must produce frictional force between feeding device and the rubber band, in case the output rate of elastic band changes great, the elastic band receives self behind the frictional force for receiving certain pulling force, because rubber band self has better elastic deformation ability, the rubber band is just elongated very easily, can exert an influence to subsequent process like this, for example cut off the process, the uneven problem of length can appear very probably in the rubber band of cutting off.

Disclosure of Invention

The utility model provides a novel rubber band feeding device; the problem of exist among the prior art rubber band in feeding the in-process easily by tensile is solved.

The above technical problem of the present invention can be solved by the following technical solutions: the utility model provides a novel rubber band feeds device which characterized in that: the bottom of the threading plate is provided with a push rod which can move up and down in a reciprocating manner and is positioned between the two threading holes, the upper surface of the threading plate is also provided with a pressing plate which can move up and down and a supporting plate which is relatively fixed, and the pressing plate can be abutted with the supporting plate.

The rubber band firstly passes through the threading hole far away from the pressing plate from top to bottom, then passes through the other threading hole from bottom to top, and finally passes through the space between the pressing plate and the supporting plate and is output backwards. The push rod is positioned on the upper side of the rubber band, when the pressing plate is abutted against the abutting plate, the rubber band stops outputting backwards, the push rod moves downwards, the rubber band at the feeding end can be pulled by one section, and after the push rod is reset, a long section of rubber band can be formed between the two threading holes; when the pressing plate is separated from the abutting plate, the rubber band can be easily drawn out. Therefore the utility model discloses be fit for the rubber band processing equipment pay-off for marching type, the rubber band can be avoided completely to take place elastic deformation among the pay-off process. The descending stroke of the push rod at each time can be determined according to the actual feeding amount.

Preferably, a rectangular closing frame is arranged on the lower side of the push rod, and the plane where the closing frame is located is perpendicular to the connecting line of the two threading holes. The closed frame is used for limiting the rubber band in the range of the push rod, and meanwhile, the rectangular frame body can reduce touch with the rubber band as far as possible, and friction force is reduced.

Preferably, the bottom of the closing frame is provided with two stop levers extending outwards. When the falling speed of push rod is very fast or the stroke that descends is long, the back is playback to the push rod, and the rubber band length of push rod downside is longer, in order to prevent that the rubber band from taking place to rock the back winding on closed frame, this problem can be avoided to the pin.

Preferably, the threading plate is provided with a long-stroke cylinder which faces downwards and can push the push rod to move up and down.

Preferably, the lower side of the threading plate is further provided with a vertically arranged guide rail, and one end of the push rod is matched with the guide rail, so that the shaking of the push rod is reduced.

Preferably, the threading plate is further provided with a short-stroke cylinder in an upward direction, the abutting plate is fixed to the upper end of the short-stroke cylinder, and the pressing plate is connected with a push rod of the short-stroke cylinder.

Therefore, compared with the prior art, the utility model has the following characteristics: 1. the mode of pulling out one section rubber band in advance through the push rod, marching type provides the rubber band, reduces the frictional force that the rubber band received, avoids the rubber band to take place deformation, guarantees that the rubber band length of output is controllable.

Detailed Description

The technical solution of the present invention is further specifically described below by way of examples and with reference to the accompanying drawings.

Example 1: see fig. 1 and fig. 2, a novel rubber band feeding device, including threading board 1 and two through wires holes 2 above that, be equipped with vertical setting and direction long stroke cylinder 7 down on the threading board 1, be equipped with horizontally push rod 3 on the piston rod of long stroke cylinder 7, push rod 3 is located the downside between two through wires holes 2 and perpendicular with the line of two through wires holes 2, still be equipped with direction short stroke cylinder 8 up on the threading board 1, two piston rod types are chooseed for use to short stroke cylinder 8, cup joint on the two piston rods and support board 5, support board 5 and short stroke cylinder upside rigid coupling, the terminal rigid coupling of two piston rods has clamp plate 4, clamp plate 4 can with support 5 butt setting.

The long stroke cylinder 7 is also fixedly connected with a front wire ring 71, and a rear wire ring 81 is arranged between the short stroke cylinder 8 and the threading hole 2 closest to the short stroke cylinder.

The rubber band is firstly led in from the front wire ring, then passes through the nearest threading hole from top to bottom, then passes through the other threading hole from bottom to top, passes through the rear wire ring and finally passes through the space between the pressing plate and the abutting plate and is output backwards. The push rod is positioned on the upper side of the rubber band, when the pressing plate is abutted against the abutting plate, the rubber band stops outputting backwards, the push rod moves downwards, the rubber band at the feeding end can be pulled by one section, and after the push rod is reset, a long section of rubber band can be formed between the two threading holes; when the pressing plate is separated from the abutting plate, the rubber band can be easily drawn out. Therefore the utility model discloses be fit for the rubber band processing equipment pay-off for marching type, the rubber band can be avoided completely to take place elastic deformation among the pay-off process. The descending stroke of the push rod at each time can be determined according to the actual feeding amount.

Referring to fig. 2, a rectangular closing frame 6 is arranged at the lower side of the push rod 3, and the plane of the closing frame 6 is perpendicular to the line connecting the two threading holes 2. The closed frame is used for limiting the rubber band in the range of the push rod, and meanwhile, the rectangular frame body can reduce touch with the rubber band as far as possible, and friction force is reduced.

The bottom of the closing frame 6 is provided with two stop bars 61 extending outwards, see fig. 2. When the falling speed of push rod is very fast or the stroke that descends is long, the back is playback to the push rod, and the rubber band length of push rod downside is longer, in order to prevent that the rubber band from taking place to rock the back winding on closed frame, this problem can be avoided to the pin.

See fig. 2 and fig. 3, the lower side of the threading plate 1 is also provided with a vertically arranged guide rail 11, and one end of the push rod 3 is matched with the guide rail 11 to reduce the shaking of the push rod.
