Abstract

The utility model discloses a tool post vertical type sealing machine, which comprises a cylinder, a gearing shaft, a connecting rod, a lower tool post, a sealing cutter, a horizontal gear rack, a tool post gear rack, a gear and a guide pole. The gear arranged on the gearing shaft is meshed with the horizontal gear rack and the tool post gear rack respectively; the guide pole is arranged on the lower tool post; the cylinder drives the horizontal gear rack to move horizontally; the horizontal gear rack drives the gearing shaft and the gear to rotate; the gear drives the tool post gear rack, and meanwhile drives an upper tool post and the sealing cutter to move up and down along the guide pole; when in use, the cylinder drives the horizontal gear rack to push the gearing shaft and the gear to rotate; and then the gear drives the tool post gear rack, thereby driving the upper and the lower tool posts to ascend or descend. The sealing machine adopts the sealing cutter which performs heating-type sealing and cutting; during the process of sealing and cutting, the sealing cutter adopts vertical-type sealing and cutting, and moves up and down straightly without the problem of uneven contact between the sealing cutter and the tool posts; the heating temperature of a shrink film to be sealed and cut is consistent; the sealing line is firm; the seal contact surface is balanced; and good sealing effects are achieved.

Description

Tool rest high low type capper

Technical field

The utility model relates to tool rest high low type capper, but its widespread use and small article (as paper handkerchief, books, laser disc, bottled drink etc.) are to the outer shrink wrapping of the product of large item (as fluorescent tube, chest etc.).

Background technology

At present, using maximum cappers is scissor sealing, as Fig. 1, shown in 2, scissor seal mainly by cylinder 1 ', fixed point 2 ', connecting rod 4 ', last lower seal tool rest 5 ', 6 ', seal cutter 7 ' and swing arm 3 ' composition, move by cylinder 1 ' doing withdraws, 8 ' drive swing arm 3 ' rotation, swing arm 3 ' drivening rod 4 ' do upward movement, connecting rod 4 ' support upper cutter head 5 ', on the contrary cylinder is done and is released action, drive swing arm 3 ' rotation, swing arm 3 ' drivening rod 4 ' do moving downward, connecting rod 4 ' upper cutter head 5 ' drive is done and moved downward, last lower seal tool rest 5 ', 6 ' round fixed point 2 ' scissor opening and closing movement of formation.Utilize the structure of fixed-point type folding to constitute to seal and employing is sealed cutter heated type envelope and cut because be, the opening and closing movement of capper is that the envelope cutter opens from the end upward movement formation away from fixed point, move downward to form and merge, cause in the process of sealing, sealing cutter 7 ' can not contact synchronously simultaneously with tool rest, and cut in the process in envelope, envelope cutter near fixed point one end is longer than the time that the envelope cutter away from fixed point one end contacts shrink film, cause the heating temperature at two ends inhomogeneous, the damaged easily fold that rises of part that time of heat is long has influenced the degree of uniformity of whole piece sealing line and attractive in appearance.

The utility model content

The purpose of this utility model is to provide a kind of tool rest high low type capper, it can overcome existing scissor sealing and rely on the fulcrum type folding, the front-end and back-end that add hot knife are different contact time with tool rest, can not realize sealing the cutter front-end and back-end synchronously envelope cut and the shrink film uneven problem of being heated.

In order to achieve the above object, the technical scheme that the utility model adopted is:

A kind of tool rest high low type capper, it comprises cylinder, transmission shaft, connecting rod, following tool rest, seals cutter, wherein: it also comprises horizontal driving rack, tool rest driving rack and gear, guide pillar, the gear of being located at down on the tool rest is meshed with horizontal driving rack and tool rest driving rack respectively, guide pillar is located at down on the tool rest, cylinder drives horizontal driving rack horizontal motion, horizontal driving rack driven gear rotates, gear driven tool rest driving rack drives upper cutter head simultaneously and seals the guide pillar lifting of tool rest down of cutter edge.

Above-mentioned tool rest high low type capper, it is to drive the band gearing shaft by horizontal driving rack to rotate, drive the driving rack motion of tool rest then again by the band gearing shaft, by this conversion of motion, be that horizontal motion is converted into up-and-down movement, more steady for making level or up-and-down movement, for example horizontal driving rack can be made as 1, transmission shaft is provided with two, and the tool rest driving rack is made as eight.

Above-mentioned tool rest high low type capper, it also can further comprise a base, cylinder, horizontal driving rack and gear all are located on the base.

Above-mentioned tool rest high low type capper, its connecting rod is four groups, and itself and tool rest driving rack are integrally formed, and four groups of tooth bars are located at the both sides of gear respectively, and its two groups link to each other with upper cutter head, and two groups link to each other with following tool rest.

After adopting said structure, during use, cylinder drives the push-jump gear of horizontal driving rack, again by gear driven tool rest driving rack, horizontal driving rack is done the horizontal motion mode and is driven two groups of tool rest driving racks drive upper cutter heads and seal cutter along descending the guide pillar on the tool rest to do upward movement by gear movement, tool rest moved downward under two groups of tool rest driving racks drove in addition, be accomplished an opening action, during the cylinder retraction, horizontal driving rack driven gear clockwise rotates, then first group of tool rest driving rack drives upper cutter head and seals cutter and move downward, second group of tool rest driving rack drives tool rest upward movement down, thereby finish once envelope and cut action, realized that the high low type envelope cuts; This is novel to be to be cut by envelope cutter heated type envelope, cut in the process in envelope, owing to be to cut with the high low type envelope, the envelope cutter is a VTOL function, do not exist the envelope cutter to contact uneven problem with tool rest, the shrink film heating-up temperature unanimity that envelope is cut, the envelope toe-in of working it out is firmly real, seal the contact surface equilibrium, reach outstanding sealing effect.

The specific embodiment

Shown in figure 3,4 and 5, the utility model discloses a kind of tool rest high low type capper, cylinder 1, the band gearing shaft 3, connecting rod 4, upper and

lower tool rest

5,6, seal cutter 7 and base 8, wherein:

It also comprises horizontal driving rack 61, tool

rest driving rack

51 and 6 gears 62, guide pillar 9, and cylinder 1,

horizontal driving rack

61 and 6 gears 62 all are located on the base 8;

Horizontal driving rack 61 is made as one, and band gearing shaft 3 is provided with two, and tool rest driving rack 51 is made as eight;

Connecting rod 4 is integrally formed with tool rest driving rack 51, and it is provided with two groups, and every group of tool rest driving rack 51 is located at the both sides of gear 62 respectively, and one group 511 links to each other with upper cutter head 5, and another is organized 512 and links to each other with following tool rest 6.
