Abstract

The utility model discloses a packing machine facilitating fastening of packing straps. One end of a ratchet shaft of the front end of a plate, which is punched through and connected by a pulling belt wheel fastener, is encased with a belt wheel, while the other end is encased with a ratchet wheel, and a pressing belt handle and a loosing belt handle are connected with the ratchet through a pawl. A wall panel is fixed with a pressing arm, where a pressing regulating part is provided. Wherein, the pressing regulating part is connected with a camshaft encased with a strap-cutting handle. The packing machine is characterized in that the other end of the pulling belt wheel is connected through a spring with the wall panel on the bottom panel. The utility model has reasonable structure and clever design. As the other end of the pulling belt wheel is connected through a spring with the wall panel on the bottom panel, the tightening force can be controlled by choosing to use different springs with different elastic forces, thus substantially enhancing the operability of the tightening procedures, and having great industrial utilization value.

Description

The compress of scalable tightening force

Technical field

The utility model relates to the packaging machinery technical field, specifically, relates to a kind 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 purpose of this utility model is, provides a kind of and can effectively overcome above-mentioned defective, the compress of scalable tightening force.

For achieving the above object, the utility model adopts following technical scheme: a kind of compress of scalable tightening force, it mainly is the DC machine that is provided with by on base plate and the base plate, tape-cutting handle and pressure, pine band handle is formed, one end of the ratchet shaft that the strap wheel attaching parts of base plate front end wears is with strap wheel, the other end is with ratchet, press, pine band handle links to each other with ratchet by ratchet, the wallboard internal fixation has clamping arm, be equipped with on the clamping arm and compress regulating part, wherein compressing regulating part links to each other with camshaft, be with tape-cutting handle on the camshaft, camshaft is connected by shift fork with cutter on the cutting knife, it is characterized in that: the opposite side of strap wheel attaching parts links to each other with wallboard on the base plate by spring.

Because adopt such scheme, be not difficult to draw as drawing a conclusion: the utility model is rational in infrastructure, be skillfully constructed, 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 the utility model is described in further detail.

Fig. 1 is a structural representation of the present utility model;

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

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.
