Abstract

The utility model relates to a device for producing driving belts, more specifically a special mechanism for manufacturing forming frame belt carcasses of driving belt products. The mechanism comprises cutting knives and a forming roller, wherein the cutting knives are evenly connected to a knife shelf, one side of which is movably connected with a main shaft. When the cutting is not needed, the transverse arm knife shelf can be rotated and is shifted out of the position of the forming roller. When in cutting, the transverse arm knife shelf returns above the forming roller and has the connection mode that one side of the knife shelf is provided with a vertical through hole, both ends of which are respectively provided with a screw nut which is matched with screw threads on the main shaft. One of the two screw nuts is used for adjusting the top and bottom position of the knife shelf, and the other one is used for tightly locking.

Description

Driving-belt cotton rope make-up machine multi-cutting machine structure

The utility model relates to a kind of equipment of producing driving-belt, specifically a kind of special mechanism of moulding skeleton belt carcass when being used to make the driving-belt product.

When production line rope band core, should afterwards respectively at multiple bonding coat of the upper and lower laminating of cotton rope and compression layer film, and, cut according to specification requirement then earlier in the whole plate uniform winding of two enterprising line ropes of format roll with its compacting.Must distinguish the radical that cotton rope is contained during cutting, because cotton rope is centre in two-layer film layers, so difficulty relatively when differentiating.

In production in the past, this cuts apart work is by the operator by rule of thumb, behind the radical of range estimation each band heart yearn rope under film, with hand cutter is cut again, and is stopped after driving to rotate a circle, then, estimates second again, cuts ...The belt carcass of one whole plate need be cut apart tens times and just can finish.Sometimes, also can estimate mistake, make unstable product quality, operator's labour intensity is also very big.

The purpose of this utility model is a kind of easy to operate, working condition good, product quality is high driving-belt cotton rope make-up machine multi-cutting machine structure of design.

Its main technical schemes comprises cutter and format roll, cutter wherein are connected on the knife rest equably, one side of knife rest and main shaft flexibly connect, when not needing to cut, rotatable transverse arm knife rest, make it shift out the position of format roll, when cutting, return the top of format roll, its connected mode is for being provided with a vertical through hole in a side of knife rest, the two ends in this hole respectively have one respectively with main shaft on the nut of threaded engagement, in these two nuts, a upper-lower position that is used to regulate knife rest, one is used for locking, and main shaft is installed on the bearing; Described cutter can be fixed on the cushion block earlier, cushion block utilizes bolt to be installed on the movable stand, there is locking nut junction at bolt and movable stand, movable stand is positioned at the groove of knife rest, connects handle in the outer end of bolt, when needs are changed the cutter of different spacing, only need the different cushion block of transposing, when needs were adjusted the horizontal level of whole cushion block, the pulling handle moved laterally movable stand and gets final product, the upper end of main shaft is connected with piston rod, piston rod is connected with cylinder body, and cylinder body is installed in the transmission mechanism, when needing cutting, start cylinder, knife rest moves down, and makes in the blade incision adhesive tape, before the used cutter blade, rear edge face width degree equates.

The utility model adopts the automatic cutting mode of induction type, and the spacing t between cutter equates that evenly when twining cotton rope and rubberizing sheet, knife rest can turn to a side of cabinet around main shaft, has avoided the influence of knife rest to shaping work; During first the cutting, the available adjustment nut is adjusted the distance of cutter point of a knife and adhesive tape, and generally this distance is about 2 millimeter, after having transferred, lock with locking nut, and then the pulling handle, to adjust the position, the left and right sides of cutter, make the edge of aiming at first cotton rope near the first cutter of head one end, start cylinder, make about 20 millimeters deep of all cutter incision adhesive tapes, make format roll rotate a circle again, whole tens belt carcass of plate just once cut and finish.

Because cotton rope is to arrange that evenly the spacing of cutter is also uniform by technological requirement, so cutter only need be aimed at one, all the other have just been aimed at entirely; Secondly, the forward and backward sword face width degree of used cutter blade equates that belt carcass is under tensioning state, and the cutting angle of cutting edge makes the cotton rope on edge of a knife both sides produce two rightabout cross forces, thereby has guaranteed carrying out smoothly of cutting; In addition,, do not have bolted to be connected,, guaranteed quality so cutter also can free thereupon play because of between the movable stand of installation cutter and knife rest if format roll is when taking place axially to vacillate in operation process.

Fig. 1 is a structure chart of the present utility model.

Fig. 2 is the cutter structure chart.

Fig. 3 is the B-B view of Fig. 2.

Fig. 4 is the A-A view of Fig. 2.

As shown in the figure: bearing 9 is arranged in the left side of format roll 12, main shaft 8 is installed on the bearing 9, there are two sections screw threads at the middle part of this main shaft 8, the upper end is connected with piston rod in the transmission mechanism 7, a wish-bone arm type knife rest 1 utilizes the longitudinal hole in its left side to be enclosed within outside the main shaft 8, and a nut 11 respectively is set at the two ends up and down and 8 on the main shaft of through hole, these two nuts 11 respectively with main shaft 8 on two sections threaded engagement, utilize nut 11 can regulate and lock transverse arm knife rest 1 on, upper/lower positions, one movable stand 2 is arranged in transverse arm knife rest 1, the cushion block 3 that cutter 4 are installed utilizes adjusting bolt 5 to be installed in the movable stand 2 with locking nut 6, outer end at bolt 5 connects one handle 10, before the blade of cutter 4, rear edge face 16,15 width equates.
