Abstract

The utility model provides a cutting blade safety protector for an adhesive tape device. The main structure is as follows: the upper part of an idler wheel arranged on the front end of the adhesive tape device is provided with a permanent seat which is provided with a grooving; the upper part of the permanent seat is provided with a slideway, the grooving and the slideway are respectively inside provided with an L-shaped stop piece and an saw-toothed cutting blade, wherein, the upper edge of the cutting blade is provided with a masking film which has the rear edge extended with symmetrical elastic pieces to achieve proper elasticity, and had the front edge of the masking film covers the edge of cutting blade. When the adhesive tape device is not used, the protection function is realized by the masking film covering the edge of the cutting blade to prevent hands of users from being cut; when the adhesive tape device is in use, the tensile force of the tape pushes the masking film to move backwards so as to expose the cutting blade to cut the adhesive tape.

Description

The cutting knife safety guard of sealing-tape machine

Technical field

The utility model relates to a kind of cutting knife safety guard of sealing-tape machine, and particularly a kind of sealing-tape machine cutting knife that prevents causes the safety guard to user's injury when not using.

Background technology

General sealing-tape machine, except being provided with spool, board, its front end is typically provided with a cutting knife, make adhesive tape after fitting, with sealing-tape machine certain angle of facing upward, cutting knife is cut off adhesive tape, the existing glue of this kind in the set cutting knife of machine owing to be exposed to board, when sealing-tape machine did not use or takes, exposed cutting knife often caused the injury to the user.

Summary of the invention

The purpose of this utility model provides a kind of cutting knife safety guard of sealing-tape machine, and the cutting knife that makes sealing-tape machine is via suitable covering, to prevent from not use or when taking, to cause the injury to the user, makes sealing-tape machine have more safety.

Above-mentioned purpose of the present utility model is to realize like this; a kind of cutting knife safety guard of sealing-tape machine; comprise handle; spool and roller; adhesive tape is sleeved on spool; treat the applying of applying thing with formation via roller; wherein: the roller top of this sealing-tape machine; be provided with a permanent seat; be provided with a grooving in this permanent seat; then establish respectively with fixed orifice the permanent seat both sides; make this grooving and fixed orifice form communicating state; after one zig-zag cutting knife is fixed in grooving; be nested with a matte in the cutting knife top; wherein; the trailing edge of this matte is to extend two shell fragments by its mediad two skew back shapes; after making matte be placed on grooving; its shell fragment end just can be attached on the fixed orifice of permanent seat both sides to form the location; in order to do when adhesive tape in not using or during joint movement; this matte is able to elasticity because of shell fragment and moves forward and be covered in the blade part of cutting knife; preventing the injury of cutting knife, and when sealing-tape machine is faced upward, then the matte ejection is made and move thereafter by the tension force of adhesive tape to the user; make the blade part emergence of cutting knife relatively, to constitute cutting to adhesive tape.

Be elaborated to of the present utility model below in conjunction with accompanying drawing.Will make the purpose of this utility model, advantage and characteristics become clearer by following explanation.

Description of drawings

Fig. 1 is a schematic perspective view of the present utility model.

Fig. 2 is a perspective exploded view of the present utility model.

Fig. 3, Fig. 4 are matte action embodiment scheme drawings of the present utility model.

Fig. 5, Fig. 6 are that the utility model band machine uses the embodiment scheme drawing.Drawing reference numeral explanation: 1 sealing-tape machine; 11 handles; 12 spools; 13 rollers; 14 permanent seats; 141 groovings; 142 fixed orifices; 15 cutting knifes; 16 mattes; 161 shell fragments; 19 chutes; 2 adhesive tapes; 20 stop tab.

The specific embodiment

Referring to Fig. 1, Fig. 2, the utility model mainly is provided with handle, spool 12 and the roller 13 as existing sealing-tape machine 1; Wherein, the top of this roller 13 is provided with a permanent seat 14, be provided with a grooving 141 in this permanent seat 14, and establish respectively with fixed orifice 142 in permanent seat 14 both sides, make this grooving 141 and fixed orifice 142 form communicating state, after one zig-zag cutting knife 15 is fixed in grooving 141, be nested with a matte 16 in these cutting knife 15 tops, wherein, the trailing edge of this matte 16 is to extend two shell fragments 161 by its mediad two skew back shapes, make matte 16 be placed on 141 after, the end of its shell fragment 161 just can be attached on fixed orifice 142, constitute positioning action, and make this matte 16 form certain elasticity;

The top of this permanent seat 14 is provided with by baffle plate 17 and the shape of the falling L chute 19 that rib 18 constitutes of dashing forward, and puts for the stop tab 20 of a L shape, makes the assembling of stop tab 20 of sealing-tape machine 1 more simple and easy, quick; Combination by aforementioned components, when sealing-tape machine 1 when not using, this matte 16 can suitably hide cutting knife 15, the user is damaged preventing, and when sealing-tape machine 1 when using, then move with emergence cutting knife 15 behind the tension force ejection matte 16 by adhesive tape adhesive tape cut off.

See also Fig. 3, Fig. 5, the utility model is not when using or attaching adhesive tape 2, adhesive tape 2 is attached at thing to be fitted by roller 13 belows, and these 16 elasticity because of shell fragment 161 of matte of being located at permanent seat 14 move forward and are covered in the blade part of cutting knife 15, in case the paired user's of major structure injury.

As Fig. 4; shown in Figure 6; the utility model is after adhesive tape 2 attachings are finished; as the action of sealing-tape machine the same; to carry on the sealing-tape machine 1; make these stop tab 20 roof pressures in adhesive tape 2; make this stop tab 20 and the adhesive tape 2 of 13 sections on roller form certain force of strain relatively; ejection by this tension force makes matte 16 slippage backward; make the blade part emergence of cutting knife 15 relatively, so, can adhesive tape 2 be cut off by cutting knife 15; finish joint movement; and after adhesive tape 2 cuts off, matte 16 again because of the elasticity of its shell fragment 161 forward slippage to hide the blade part of cutting knife 15, to reach the purpose of safety guard-safeguard.

In sum, the utility model is provided with the matte of shell fragment, makes sealing-tape machine in not using or during joint movement, cutting knife suitably being covered, and to prevent the injury to the user, reaches the safety guard-safeguard effect.
