Abstract
The utility model provides a heat-sealing-line non-stretching cold cutting bag machine equipped with a feeding control device. The heat-sealing-line non-stretching cold cutting bag machine comprises a heat sealing knife and a cold cutting knife; a group of heat sealing feeding rollers is arranged in front of the heat sealing knife; the feeding control device, which consists of an oscillating rod and a micro switch, is mounted on the upper surface of a dropping edge of a loosening section of the raw material between the heat sealing knife and the cold cutting knife; the micro switch is arranged above the front surface of the oscillating rod; the signal output end of the micro switch is connected with a controller of the device to control the action of a cold cutting feeding roller. The heat-sealing-line non-stretching cold cutting bag machine equipped with the feeding control device has the advantages that the oscillating rod is driven to oscillate while the raw material is tensioned, then the micro switch is triggered by the oscillating rod under oscillating to send a signal to a controller of the machine, and finally the cold cutting feeding roller is controlled through the signal to act, thus excessively tight or loose raw material loosening section is avoided, the difference between a heat sealing line and a cold cutting line of each product is greatly reduced, the consistency of the products is raised, the continuous production is ensured, and as a result, the production efficiency is raised.
Description
Technical field
The utility model relates to a kind of hot-sealing line that feed control device is housed without stretching cold cut Bag Making Machine, at existing hot-sealing line, sets up feed control device on without stretching cold cut Bag Making Machine.
Background technology
Prior art is that a kind of hot-sealing line is without stretching cold cut Bag Making Machine, its primary structure comprises material axle, the first feeding roller, feed-control device, heat-fastening knife, the second feeding roller and cold cutter, the package raw material of material on axle is transported to (between have feed-control device to control feeding amount) heat-fastening knife by the first feeding roller and carries out heat seal (hot pressing goes out at least one hot pressing line on raw material), then by the second feeding roller, is transported to cold cutter and cuts.One group of heat seal feeding roller is set before described heat-fastening knife, blowing device is set after heat-fastening knife, so that the raw material between heat-fastening knife and cold cutter produces a slack strand, and utilize blowing device to carry out slight brushing to this raw material slack strand, keep unfolding and adhesion of this slack strand.Generally in the front and back of heat-fastening knife, being respectively provided with one unfolds platform, photoelectric sensor can be installed on unfold platform for the track and localization to printed patterns.When being processed with the product of printed patterns (polybag), can utilize photoelectric sensor to control the operating frequency of cold cutter, can guarantee the dimensional accuracy (uniformity) of each product of cutting out.But in processing during without the polybag of printed patterns, just there is no framing signal (output of photoelectric sensor no signal), due to a variety of causes (as difference of the slip of raw material and front and back feeding roller size etc.), there is small difference in the charging length of raw material, the accumulation of this minute differences not only affects the uniformity (being mainly the uniformity of the spacing between hot thread and cold cut line) of product size, also can cause the slack strand of raw material more to relax or tension, too lax meeting causes raw material adhesion, and the result of tension can cause raw material to stretch or disconnect, both of these case all can cause the interruption of producing, not only wasted raw material, also reduced production efficiency.
Summary of the invention
The utility model aims to provide a kind of hot-sealing line that feed control device is housed without stretching cold cut Bag Making Machine, with solve that prior art exists in processing during without the polybag of printed patterns, the problem of the more lax or tension of the slack strand of raw material.
The technical solution of the utility model is: a kind of hot-sealing line that feed control device is housed is without stretching cold cut Bag Making Machine, comprise heat-fastening knife and cold cutter, one group of heat seal feeding roller is set before described heat-fastening knife, being provided with above of cold cutter, cold cut feeding roller, above the slack strand producing at the raw material between heat-fastening knife and cold cutter, be provided with blowing device, it is characterized in that, one feed control device is housed on the trailing edge of described slack strand, this feed control device comprises fork and microswitch, above before this fork, be provided with microswitch, the signal output part of this microswitch is connected with the controller of equipment, for controlling the action of cold cutter.
Described fork is comprised of horizontal pipe and LL, laterally the two ends of pipe respectively with vertical connection of one end of a LL, the other end and the frame of LL are hinged.
Damping unit is equipped with in one or both ends at described bearing pin.
Described damping unit is comprised of bolt and helical spring, and bolt is coaxially connected in the axle center screw on described bearing pin top, and helical spring is enclosed within on bolt.
The utility model has the advantages that: when raw material is strained, drive fork swings, fork swings and triggers microswitch, the latter sends a signal to the controller of machine, with the action of this signal controlling cold cut feeding roller, the slack strand of having avoided raw material too tightly or too lax situation occur, greatly reduce the hot-sealing line of each product and the difference between cold cut line, improved the uniformity of product, guaranteed the continuity of producing, and then improved production efficiency.
Accompanying drawing explanation
Fig. 1 is general structure schematic diagram of the present utility model;
Fig. 2 is a left side (right side) view of fork in Fig. 1.
The specific embodiment
Referring to Fig. 1 and Fig. 2, a kind of hot-sealing line that feed control device is housed of the utility model is without stretching cold cut Bag Making Machine, comprise from left to right rack-mounted material axle 1, preposition feeding roller 3, feed-control device (curtain keeps the state of unfolding of raw material) 4, heat-fastening knife 7, cold cut feeding roller 10 and cold cutter 11.Between above-mentioned each device, necessary roll shaft 2 is also housed, for bag raw material 13 is unfolded to location; What be located in addition heat-fastening knife 7 front and back (being the left and right in accompanying drawing) unfolds platform 5(also for the track and localization to printed patterns, this kind of situation installed photoelectric sensor 17 up), below unfold platform 5 be provided with below cold cut feeding roller 10 and cold cutter 11.One group of heat seal feeding roller 6 is set before described heat-fastening knife 7, blower 8 is set after heat-fastening knife 7, so that the raw material between heat-fastening knife and cold cutter produces a slack strand 9, and utilize 8 pairs of these raw material slack strand 9 of blower to carry out slight brushing, keep unfolding of this slack strand 9, prevent the normal work of adhesion impact.
Described heat seal feeding roller 6 and heat-fastening knife 7 vertically arrange up and down, make raw material 13 move from the top down (as shown in Figure 1).Described heat seal feeding roller 6 and heat-fastening knife 7 also can left and right horizontally sets, make raw material 13 transverse horizontal move (not shown).
