Description

Hand-held design banding machine packing tape fusion splicing devices

The utility model relates to packing machinery technology, refers in particular to a kind ofly to dwindle the banding machine entity and use hand-held design banding machine packing tape fusion splicing devices more easily.

The hand-held design banding machine is common in the joint sealing operation now, be used for a kind of utensil that binding and packing box or casing avoid the in-to-in article to shed, and can reach the effect of convenient transportation behind joint sealing, therefore for manufacture, banding machine is considerable shrink-wrap instrument; It mainly utilizes the outer rim of the packing tape of one section suitable length around packing box, clamp packing tape with pinch roller again, and rotate this pinch roller and produce clamping force with the tension packing tape, make it tightly to be around in packing box, and then utilize shutoff device with the welding of packing tape overlapping part, ability actv. binding and packing box like this; See accompanying

drawing

1,2, shown in 3, fusion splicing devices 1 and shutoff device 2 are installed on the biside plate 31 of banding machine 3, on 32, and wherein has a banded carrying surface 34 between the edge of the base plate 33 of side plate 31 and banding machine 3, put the local lap 41 of the packing tape 4 of article on the spot in order to the carrying bundle, and this lap 41 includes a top packing tape 411 and a below packing tape 412, and its section direction is provided with a friction head 11, the bottom of this friction head 11 has a projecting teeth portion 111, in order to pressure put the top packing tape 411 after, drive via the sliding shoe in the slide mechanism 12 121, and make this top bundling belt 411 in laterally reciprocating, make top packing tape 411 and below packing tape 412 take place to rub and be welded together; This slide mechanism 12 includes sliding shoe 121, one crank 122, one camshaft 123, be installed on this base plate 33 and limit the lid 124 that this slide mechanism 12 only can laterally do reciprocating linear motion, an and high-speed motor 125, motor 125 drives camshaft 123 rotations with a belt 126, camshaft 123 interlock cranks 122 are made the fast speed crank motion with sliding shoe 121, these sliding shoe 121 1 ends are to have a breach 127 that can supply friction head 11 to insert from vertical direction, and friction head 11 just can be in this breach 127 moves arbitrarily and puts the position of pushing down or do not push down bundling belt 411 above this, while can be vised by breach 127 again and along with sliding shoe 121 is laterally being made the fast speed crank motion, be made these packing tape 4 local laps 41 because of the friction welding; Though above-mentioned fusion splicing devices 1 has the function of welding packing tape 4, but, still there is following disappearance: 1, drive camshaft 123 rotations by motor 125 drive belts 126 because fusion splicing devices 1 is a nationality, camshaft 123 interlock cranks 122 are made fast speed reciprocating friction packing tape 4 with sliding shoe 121, and with local overlapped part 41 weldings, but for the user, not only need periodical maintenance but also can increase again to change the required cost of belt 126.2, the belt 126 of fusion splicing devices 1 is to be used to link motor 125 and camshaft 123, therefore also belt 126 corresponds to required relative will the increase of accommodation space of motor 125 and camshaft 123, yet, for a hand-held design banding machine 3, its volume is big more can to become not convenient in the use, and if belt 126 is near motor 125 sides, is subjected to motor 125 influencing of heat radiation and produces qualitative change with regard to easy more.That is, the main purpose of this creation is for providing a kind of packing tape fusion splicing devices that dwindles the banding machine entity and use more convenient hand-held design banding machine.

The purpose of this utility model is to provide a kind of banding machine entity and hand-held design banding machine packing tape fusion splicing devices easy to use of dwindling.

The purpose of this utility model is achieved by the following technical solution: eccentric wheel one end face of transmission device is connected with motor, the other end is connected with connecting rod, be installed with friction head on the connecting rod other end, friction head is positioned at the local overlapping part top of packing tape, the brake block of banding machine is positioned at the bridge formation of friction head to be withstood and makes its below that produces the bridge formation of upper and lower displacement, and is placed in the conduit of spacer; The control lever of interlinked mechanism places on the banding machine, and is placed through the brake block below.

The friction head top has one can the stopper friction head, make friction head produce the bridge formation of upper and lower displacement; The position that the control lever stopper friction head that micro-switch is fixedly arranged on interlinked mechanism can be activated when pushing down packing tape; Spacer is placed by torque spring on the tool rest of shutoff device, and a spacing hole is arranged at the top of its conduit; One fluting is arranged on the tool rest of shutoff device; The handle of tightening device is provided with a return unit with respect to the end of spacer.

The utility model motor directly drives the eccentric wheel rotation, make friction head reciprocating friction packing tape apace by the eccentric wheel drive link again, make the local overlapping part welding of packing tape, therefore banding machine does not have consumable components needs to change, for the user, can not produce the puzzlement of usually changing spare part, its drive connection is comparatively close, the physical size that can dwindle banding machine after each spare part assembling is used more light.
