Description

Tensioning roller frame for thin film

Technical Field

The utility model belongs to film equipment field, concretely relates to tensioning roller frame for film.

Background

The tension rolls are frequently used and replaced when producing films. The tensioning roller is usually made of stainless steel, the length is about 2 meters, so the tensioning roller is heavy, the disassembly and the replacement are inconvenient, at least two persons are required to cooperate with each other to operate, the labor intensity is high, and the efficiency is low. At present, the tension roller that changes is usually placed on a roll stand, sets up the buckle by the nut is fixed on the roll stand. The operation of replacing the roller frame is realized by pushing the roller frame to walk between the devices. However, the process of fixing the tension roller needs tools such as a wrench, the tension roller cannot be directly transferred to the equipment from the roller frame, only two persons can be matched, and after the tension roller is taken down from the roller frame, the tension roller is assembled on the equipment, so that the efficiency is not high.

Disclosure of Invention

In order to overcome the problem, the utility model provides a tensioning roller frame for film high-efficient, facilitate the use.

The technical scheme of the utility model a tensioning roller frame for film is provided, it includes the support, the support includes upper beam and underbeam, be provided with a plurality of buckle on the upper beam, the underbeam includes that a plurality of can wind the rotatory piece of underbeam axis, every all be provided with one on the rotatory piece and supply tensioning roller male through-hole.

Preferably, one end of each rotating block is provided with a ball head, the other end of each rotating block is provided with a blind hole capable of accommodating the ball head of the adjacent rotating block, and the rotating blocks are connected into the lower beam.

Preferably, an annular groove is formed in the joint of the ball head and the rotating block, a threaded hole is formed in the position, corresponding to the groove, outside the blind hole, and a fastening screw is in threaded connection with the threaded hole.

Preferably, the lower beam further comprises a fixed ball head and a fixed blind hole which are arranged on the bracket.

Preferably, a plurality of grooves are formed in the upper beam, each buckle comprises two crescent-shaped clamping blocks with pivots arranged on the sides of the grooves, one clamping block is provided with a connecting belt on the outer side, and the connecting belt is detachably connected to the other clamping block through a snap fastener.

The tensioning roller frame for the film accelerates the fixing efficiency of the tensioning roller by improving the buckle structure of the upper beam; through the structure of improving the underbeam for the tensioning roller can one end be placed on the underbeam, and the wide-angle slope under operation alone, one end is fixed to equipment, thereby realizes that assembly operation can be accomplished alone, has improved efficiency.

Detailed Description

The following describes in further detail embodiments of the present invention.

As shown in fig. 1 to 3, the present invention provides a tension roller frame for a film, which includes a bracket 10 having a wide lower part and a narrow upper part. The support 10 comprises an upper beam 12 and a lower beam 14, wherein the upper beam 12 is provided with a plurality of buckles 16, the lower beam 14 comprises a plurality of rotating blocks 18 which can rotate around the axis of the lower beam 14, each rotating block 18 is provided with a through hole 20 for inserting a tension roller, when the support is placed, the upper end of the tension roller is fixed through the buckles 16, and the lower end of the tension roller is inserted into the through hole 20 and is placed on the support 10 in a slightly inclined mode. When the tension roller is taken, firstly, the upper end is loosened, the upper end of the tension roller is placed on a machine, and the lower end of the tension roller rotates along with the rotating block 18 to keep supporting; after the upper end of the tensioning roller is fixed, the lower end of the tensioning roller is taken down and placed on a machine.

One end of each rotating block 18 is provided with a ball head 22, the other end of each rotating block is provided with a blind hole 23 capable of accommodating the ball head 22 of the adjacent rotating block 18, the lower beam 14 further comprises a fixed ball head 24 and a fixed blind hole 26 which are arranged on the support 10, and the two ends of the plurality of rotating blocks 18 are connected with the fixed ball head 24 and the fixed blind hole 26 respectively, so that the complete lower beam 14 is formed (only the structure of part of the rotating blocks 18 is shown in figure 1, and more rotating blocks 18 are combined, so that the assembly of the lower beam 14 can be completed).

An annular groove 28 is formed in the joint of the ball head 22 and the rotating block 18, a threaded hole 30 is formed in the position, corresponding to the groove 28, outside the blind hole 23, a fastening screw 32 is in threaded connection with the threaded hole 30, the ball head 22 is limited through the fastening screw 32, and the ball head 22 is prevented from being separated from the blind hole 23.

The upper beam 12 is provided with a plurality of grooves 28, the buckle 16 comprises two crescent-shaped blocks 34 which are pivotally arranged at the sides of the grooves 28, a connecting belt 36 is arranged outside one block 34, and the connecting belt 36 is detachably connected to the other block 34 through a snap fastener (only part of the structure of the block 34 is shown in fig. 2). After the tension roller is placed in the groove 28, the fixture block 34 is pressed to rotate, a holding structure is formed, and the connecting belt 36 outside the fixture block 34 is fixed, so that the fixture block 34 is prevented from falling out.

The above embodiment is only one embodiment of the present invention, and the description thereof is specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
