Detailed Description

In order that the utility model may be more readily understood, a more particular description of the utility model will be rendered by reference to specific embodiments that are illustrated in the appended drawings.

Embodiment 1 referring to fig. 1 and 2, the present embodiment provides a press roller mechanism, which includes a first press roller assembly, a second press roller assembly and a tension adjusting assembly that are used in cooperation.

The following is in particular with reference to the accompanying drawings:

First is a first press roll assembly comprising at least a first press roll 3 and a fixed abutment for forming a self-rotating support for the first press roll 3. The fixed supporting seat comprises a pair of fixed seats 2 fixedly assembled on one supporting plate 1 and respectively matched with two shaft side ends of the first compression roller 3. The two axial side ends of the first press roller 3 and the pair of fixed seats 2 form a rotating fit relationship, so that the first press roller 3 can smoothly perform autorotation motion relative to the pair of fixed seats 2.

Next is a second press roll assembly comprising a second press roll 7 and a movable abutment for forming a self-rotating support for the second press roll 7. The movable supporting seat adopted in the embodiment comprises a pair of connecting seats 4 fixedly connected with one supporting plate 1, and a pair of movable seats 5 which are movably matched with the pair of connecting seats 4 and are respectively matched with two shaft side ends of a second press roller 7. Each connecting seat 4 is matched with each movable seat 5, the movable seats 5 can be hinged with the connecting seats 4 through pin shafts, and each movable seat 5 is connected with one fixed seat 2 through a pre-tightening elastic piece 6. Here, the two shaft side ends of the second press roller 7 form a rotation fit relationship with the pair of movable seats 5, so that the second press roller 7 itself can perform a smooth rotation motion with respect to the pair of movable seats 5.

On the basis of the above structure, it should be further explained that, for the support plate 1 connected to the engagement seat 4, the support plate 1 may be the same support plate 1 that is matched with the fixing seat 2, or may be two independent support plates 1, which is not limited in any way.

For example, in an alternative embodiment, the movable seat 5 is an L-shaped structure, one end of the movable seat 5 is movably engaged with the engagement seat 4, and the other end of the movable seat 5 is connected with the pre-tightening elastic member 6. The structure can enable the connecting seat 4 and the fixing seat 2 to be arranged on the supporting plate 1 in parallel, and for this purpose, through the design of the L-shaped structure body, a third press roller 8 which is arranged opposite to the first press roller 3 can be further connected between the pair of connecting seats 4, interference can not be formed between the second press roller 7 and the third press roller 8, and the operation can be relatively independent. The passage of the conveyor belt is thus formed by the relative arrangement of the first 3 and third 8 press rolls, while the second press roll 7 is used for forming an adjustment of the tension of the belt. For the present embodiment, the material belt may be a film, or may be other film materials, which is not limited in any way.

Furthermore, the tension adjusting assembly at least comprises a pre-tightening elastic piece 6 arranged between the movable supporting seat and the fixed supporting seat. More specifically, in view of the convenience of installation, the tension adjusting assembly herein further includes connection lugs 9 provided at both ends of the pre-tightening elastic member 6 for respectively connecting the fixed seat 2 and the movable seat 5.

Based on the above, the pre-tightening elastic member 6 is adapted to change its pre-tightening force to drive the movable supporting seat to move synchronously, so that the tension of the material belt is kept stable during the conveying process between the first press roller 3 and the second press roller 7. The pre-tightening elastic member 6 can be, for example, but not limited to, a spring, the pre-tightening force of which is adjusted by the telescopic deformation of the spring, and the spring is suitable for deformation when the tension of the spring changes in the processing process of a specific material belt, so that the second press roller 7 is driven to move, and the tension of the material belt is kept stable.

As will be explained in detail in connection with the figures, the axis of the second press roll 7 is parallel to the axis of the first press roll 3, and the movable support is adapted to adjust the distance between the axes of the first press roll 3 and the second press roll 7 when it is moved by the pretensioning elastic member 6, i.e. to keep the tension of the web transported by the first press roll 3 and the second press roll 7 stable by adjusting the distance between the axes of the first press roll 3 and the second press roll 7.

To sum up, for the press roller mechanism of this embodiment, the tension adjusting component not only can satisfy the adjustment to the use process of the second press roller 7, but also the whole tension adjusting component is of an external structure, so that the installation is easy, and the disassembly and replacement of parts are also more convenient.

Based on the above, it should be noted that any known method may be used for the guide roller mechanism, and this embodiment is not limited in any way, and generally the guide roller mechanism includes two guide roller bodies 11 that are oppositely disposed and adapted to rotate to form a film conveying path.

In addition, the air knife mechanism can also adopt a mature means in the prior art, and the embodiment is not limited in any way. In an alternative form, illustrated in the accompanying drawings, the air knife mechanism comprises two air knife assemblies arranged oppositely for forming a film conveying channel, wherein each air knife assembly at least comprises an air knife main body 12 and an air knife body 13 connected with the air knife main body 12,

The air outlet is arranged on the air blowing cutter body 13.

On the basis of the above structure, further, the air knife body 13 is movably matched with the air knife main body 12 to be suitable for adjusting the air outlet angle of the air knife body 13 relative to the air knife main body 12, and the air knife body 13 is rotatably matched with the air knife main body 12 through the pin shaft 15, so that in order to meet the use requirement, an arc-shaped limiting groove 14 for limiting the rotation angle of the air knife body 13 is further formed on the air knife main body 12, and the air knife body 13 is also matched with a limiting column 16 suitable for moving along the arc-shaped limiting groove 14. Under this structure, combining the dry user demand of actual material area, can manually rotate the cutter body 13 of blowing, make it rotate certain angle relative to air knife main part 12 to improve the flexibility that this air knife mechanism used.
