Abstract
The utility model relates to the field of machines, in particular to a gluing device glue roller driving block which comprises a driving block body. Transmission keys are arranged on the face where the driving block body is in contact with a gluing roller, the number of the transmission keys is more than one, and the two transmission keys are symmetrically distributed around the center of the contact face. Compared with the prior art, the gluing device glue roller driving block has the advantages that according to the working characteristic that the key connection achieves circumferential fixation between a shaft and parts on the shaft through the keys so as to transmit the motion and torque, driving for transmitting the gluing roller is changed into flat key transmission from a transmission pin, and the torque is transmitted by means of the extrusion of the side walls of key grooves. Meanwhile, according to the width and the height of each flat key, a transmission groove is formed in the end face of the gluing roller in a milling mode, and the aim of transmitting power is achieved. The increasing of the contact area of the driving portion certainly will greatly reduce the abrasion degree.
Description
Technical field
The utility model relates to mechanical field, relates in particular to rubberizing device rubber roll driving block.
Background technique
One. phenomenon of the failure:
1.ZJ112 cigarette type rubberizing device in use, often can wear and tear or fracture in driving pin GB/T119.1-5m6 on the rubber roll driving block * 12, cause upper glue roller when moving in a circle around back shaft, upper glue roller has pause and stall phenomenon, at this moment, very easily occur cigarette fall to chew, gas leak phenomenon, have a strong impact on quality of product;
2., component complicated because of the gluing transmission structures are installed compactly, and this position rear maintenance time spent of breaking down is longer;
Two. As-Is analysis:
The power of upper glue roller comes from the driving pin on the rubber roll driving block in the rubberizing device, and in Machine Design, the purposes of straight pin is very extensive.It has mainly played the connection that strengthens coupling, the effect of transmitting torque and power.In application, straight pin also mainly plays the effect of location or centering except than the coupling intensity height.In rubberizing device, driving pin has just played the effect of transmitting torque and power.So, why can driving pin wear and tear in the process of transferring power? calculate by analysis shearing stress, flexural stress and the extrusion stress of driving pin.Find that the driving pin diameter is less than normal, shearing stress and flexural stress are lower than and meet with stresses, so, in use, easily wearing and tearing.
The model utility content
The purpose of model utility: in order to solve above technical problem, so that parts are longer service time, reduce wear.
In order to reach as above purpose, the utility model is taked following technological scheme:
Rubberizing device rubber roll driving block is characterized in that, on the surface of contact of driving block and upper glue roller driving key is arranged, and described driving key is one of following two kinds of structures: described driving key is projection, also comprises the driving groove of upper glue roller end face, and described driving key and driving groove agree with; Perhaps described driving key is driving groove, also comprises the projection of upper glue roller end face, and described driving key and projection agree with.
The further technological scheme of the utility model is that described driving key has more than one.
The further technological scheme of the utility model is that described driving key is uniform on surface of contact.
The further technological scheme of the utility model is, described driving key has two and distribute around the Central Symmetry of surface of contact.
The further technological scheme of the utility model is that described driving key is flat key.
Adopt as above the utility model of technological scheme, with respect to prior art following beneficial effect is arranged: connecting according to key is to realize circumferentially fixing to transmit the work characteristics of motion and torque between axle and parts on shaft by key, the driving of transmission upper glue roller is improved to the flat key transmission by driving pin, by key slot side extruding transmitting torque.According to width and the height of flat key, mill out driving groove at the upper glue roller end face simultaneously, reached the purpose of transferring power.The increase of driving part area of contact will certainly make the degree of wear greatly reduce.
Description of drawings
In order to further specify the utility model, further describe below in conjunction with accompanying drawing:
Fig. 1 is the structural representation of model utility;
Wherein: 1. driving block, 2. driving key.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described, embodiment does not consist of restriction of the present utility model:
Strengthen the driving pin diameter if adopt, strengthen its shear stress values and flexural stress value, to reach anti-wear effect.But, the rubber roll driving block limited space of driving pin is installed, strengthen the driving pin diameter, just must reaming on original pin-and-hole, driving pin hole wall and rubber roll driving block inwall gap are too little after the reaming, fragile rubber roll driving block.
Therefore, this novel scheme of taking is as follows: comprise driving block 1, on the surface of contact of itself and rubber roll driving key 2 is arranged.
Described driving key 2 has more than one.Described driving key 2 is uniform on surface of contact.So its stress balance, longer service life.
Described driving key 2 has two and distribute around the Central Symmetry of surface of contact.The number at this place does not cause restriction to implementation of the present utility model.
Described driving key 2 is projection, also comprises the driving groove of upper glue roller end face, and described driving key 2 and driving groove agree with.
Can certainly be following a kind of situation: described driving key 2 be driving groove, also comprises the projection of upper glue roller end face, and described driving key 2 and projection agree with.
Described driving key 2 is flat key.
More than show and described basic principle of the present utility model, major character and advantage of the present utility model.Those skilled in the art should understand the utility model and not be restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in the claimed scope.
