CN101092181A - Technique for manufacturing packer capable of adjusting tightening force - Google Patents

Abstract

The invention discloses a process for making a packer able to regulate tension, mainly comprising the step of providing a spring on the other side of a tape drawing wheel connecting piece to connect with wall plate on the soleplate. Its process is reasonable and its design is skillful, and the tension magnitude can be completely controlled by selecting a different spring so as to extremely improve the operability of tensioning procedure and have great industrial utilization value.

Description

The manufacturing process of the compress of scalable tightening force

Technical field

The present invention relates to the packaging machinery technical field, specifically, relate to a kind of manufacturing process of packing apparatus.

Background technology

At present, all kinds of compresses on the market, constantly lift during packing press to press, pine band handle tightens up strap, but in tightening process, tends to feel that the tightening force size that strap wheel tightens up strap can't control.Sometimes tension is loose excessively sometimes.

Summary of the invention

The objective of the invention is to, provide a kind of and can effectively overcome above-mentioned defective, the manufacturing process of the compress of scalable tightening force.

For achieving the above object, the present invention adopts following technical scheme: a kind of manufacturing process of compress of scalable tightening force mainly comprises following steps: the opposite side of A. strap wheel attaching parts provides a spring, makes it to link to each other with wallboard on the base plate.

Because adopt such scheme, be not difficult to draw as drawing a conclusion: technology of the present invention is reasonable, is skillfully constructed, the compress of the scalable tightening force that produces is because the opposite side of strap wheel attaching parts links to each other with wallboard on the base plate by spring.So the size of tightening force can be controlled by selecting the different spring of elastic force for use fully, thereby greatly improve the operability of tightening up operation, has industrial utilization.

Description of drawings

Below in conjunction with drawings and Examples invention is described in further detail.

Fig. 1 is the structural representation of the compress of the scalable tightening force that produces of the present invention;

Fig. 2 is the back view of Fig. 1;

Fig. 3 is the side dextrad view after Fig. 1 removes tape-cutting handle.

The specific embodiment

A kind of manufacturing process of compress of scalable tightening force mainly comprises following steps: the opposite side of A. strap wheel attaching parts provides a spring, makes it to link to each other with wallboard on the base plate.The structure of the compress of the scalable tightening force that the present invention is produced below in conjunction with accompanying drawing describes in further detail.Referring to Fig. 1, link to each other with strap wheel attaching parts 190 on the engaging lug of base plate 210 front ends, an end of the ratchet shaft 90 that strap wheel attaching parts 190 wears is with strap wheel 30, and the correspondence position under the strap wheel 30 then is provided with the pressure zone plate 40 of dentation.The other end is with ratchet 80, and pressure, pine band handle 10 link to each other with ratchet 80 by ratchet.Referring to Fig. 2, the opposite side of strap wheel attaching parts 190 links to each other with wallboard 200 on the base plate 210 by spring 230, and wallboard 200 internal fixation have clamping arm 140, are equipped with on the clamping arm 140 to compress regulating part 240.Compress regulating part 240 referring to Fig. 3 and be provided with pressure roller 120 by pin.Referring to Fig. 2, compress adjusting screw(rod) 130 and pass the screw that is threaded onto clamping arm 140 behind the opening part that compresses regulating part 240, compress and be with arch spring 250 on the adjusting screw(rod) 130.Referring to Fig. 1, clamping arm 140 is connected with pressure zone spare pitman 110 by pin, pressure zone spare pitman 110 is connected with swing arm 150 and swing tooth plate 70 by pin, the base plate 210 of 70 corresponding position is provided with fixed tooth plate 60 under the swing tooth plate, and swing arm 150 links to each other with the eccentric shaft 100 that links to each other with DC machine 50.Referring to Fig. 3, wherein compress regulating part 240 and link to each other with camshaft 180, be with tape-cutting handle 20 on the camshaft 180, cutter on camshaft 180 and the cutting knife 170 160 are connected by shift fork, and cutter 160 are provided with permanent magnet 220.Its working process of brief description, to press earlier, pine band handle presses down, make on the strap wheel and lift, strap is penetrated, lift pressure, pine band handle afterwards repeatedly, until with tighten packing belt, depress tape-cutting handle then, cut off strap by cutter, permanent magnet drives source switch simultaneously, DC machine drives eccentric shaft and rotates, and the downward high speed crank motion of swing arm rubs the strap between swing tooth plate and fixed tooth plate closely, the heat that produces makes the strap fusion, at this moment, depress, pine band handle unclamps band and extract out, packing process is promptly accused and is finished.

Claims (1)

1, a kind of manufacturing process of compress of scalable tightening force mainly comprises following steps: the opposite side of A. strap wheel attaching parts provides a spring, makes it to link to each other with wallboard on the base plate.
