Detailed ways

Please refer to Fig. 3 to Fig. 4, which is a preferred embodiment of a film applicator of the present invention, which mainly includes a base 10, a stopper 20 and a brake sleeve 30; wherein:

The base 10 is an elongated cylinder, and a limiting groove 11 is recessed on the circumferential surface in the middle of the base 10, so that the base 10 is separated by the limiting groove 11 so that the rear end forms a gripping portion 12. The front end forms a hub-shaped applicator 13 with a diameter larger than that of the gripping part 12, and the outer peripheral surface of the applicator 13 is equidistantly provided with several ribs 131, and the applicator 13 is used to be tightly assembled on a film roll 200 On the core of the applicator part 13, a neck 14 with approximately the same diameter as the grip part 12 is formed by converging around the end of the applicator part 13 towards the direction of the limiting groove 11, and a protruding arrangement is formed between the applicator part 13 and the neck part 14. There is a convex portion 132 for butting against the film roll 200 inserted into the application portion 13 .

The limiting member 20 is composed of two semi-annular bodies to be placed in the limiting groove 11 to form a ring shape, wherein the inner diameter of the limiting member 20 is slightly larger than the circumference of the limiting groove 11 surface, so that the base body 10 can pivot on the limiting member 20 , and the outer ring surface of the limiting member 20 forms a tapered surface 21 tapered towards the grip portion 12 .

The brake bushing 30 is made of a flexible rubber material, a hollow tube body with a closed bottom end and an open upper end, and has an accommodating groove 31 slightly larger than the pipe diameter of the gripping portion 12 . The groove depth of the accommodating groove 31 can be nested on the holding portion 12 of the base body 10 to the position of the limiting groove 11, so that the hand can hold it properly, and the end of the holding portion 12 is just against the accommodating portion. At the bottom of the groove 31, a conical limiting flange 311 is gradually protruded toward the axis at the inner periphery of the opening end of the accommodating groove 31, and at an appropriate distance below the limiting flange 311 On the inner peripheral surface of the accommodating groove 31, several rib-shaped brake bars 312 are equidistantly protruded along the long axis direction, and a spacer 20 is formed between the spacer flange 311 and these brake bars 312. The clamping part 313 is accommodated, and the size of the clamping part 313 is just equal to the size of the outer ring surface of the limiting member 20, which can be used to clamp the limiting member 20 on the inner peripheral surface of the brake bushing 30. In addition, A shoulder 314 with a smaller diameter protrudes from the lower edge of the inner circumference of the accommodating groove 31 toward the axis, so that the lower end of the holding part 12 can be placed in the shoulder 314, and the brake sleeve 30 An annular cap edge 315 protrudes laterally outward from the outer ring surface of the opening end, which can effectively prevent the film roll 200 from being touched by hand when operating the film roll 200 .

In order to further understand the structural features of the utility model, the use of technical means and the expected effects, the usage of the utility model is described hereby. It is believed that the utility model can have a deeper and more specific understanding, as follows:

First, place the limiting member 20 on the limiting groove 11 of the base body 10, and then put the holding portion 12 of the base body 10 into the accommodating groove 31 of the brake bushing 30, and the brake sleeve The stopper flange 311 of the tube 30 is against the bottom of the stopper 20 of the base body 10, and then pressed down into the base body 10 into the accommodating groove 31 by holding the application part 13, and the base body 10 passes through the stopper The part 20 then squeezes into the clamping part 313 below the limiting flange 311, so that the limiting part 20 is limited by the limiting flange 311 and clamped in the clamping part 313, and the lower end of the gripping part 12 The outer circumference can just be placed in the shoulder 314 of the accommodating groove 31, so that the base body 10 can be pivoted in the brake bushing 30, and the assembly step of the film applicator is completed. Next, The application part 13 of the film applicator can be inserted into the core of the film roll 200, and the application part 13 utilizes the ribs 131 on it to firmly position the film roll 200 so that the film roll 200 can pass through The base body 10 is linked. When packing objects, the user can hold the brake sleeve 30 and move in a predetermined direction on the object. By rotating the base body 10, the film roll 200 can be released smoothly. Please refer to As shown in Fig. 5, a radial force can be applied to the brake sleeve 30 in good time, so that the brake sleeve 30 can be deformed and extruded, so that the brake strip 312 on the inner peripheral surface can resist the rotating base. 10. Then brake to stop the film, and continue to hold it tightly to adjust the film packaging tightness, control the film tension, and then relax the radial force applied to the brake sleeve 30, so as to continue the packing action , so the utility model can achieve the bale braking effect by operating the brake sleeve 30, so as to prevent the problem of insufficient bale tightness after the film reel 200 is out of the film for a period of time, and then achieve a good bale package effect.

Hereby, the features of the present utility model and the expected effect that can be achieved are stated as:

1. The limit piece on the base of the utility model is clamped in the brake sleeve, so that the base can pivot in the limit piece, and the film roll is rotated in conjunction with it, so that the user can hold The brake bushing applies a radial force to it in good time to stop the rotation of the base body, so that it can adjust the packing tightness of the film to achieve a good packing effect.

2. The film applicator of the present utility model is quite simple and convenient in assembling components, and is also quite convenient in use, so it can effectively save assembly materials and achieve the practicability of saving packing effort.
