Description
- The present invention relates to a plastic film guiding device of a packaging machine and, more particularly, to a moving structure of a guiding device, which is capable of simultaneously controlling the widths of both sides.
- FIG. 1 shows a prior art guiding device of packaging plastic film, wherein a pair of
dissymmetrical bottom plates 11 are locked on a machine table, and a width-adjustingrod 12 is locked slantingly on the surface of each of thebottom plates 11. The width-adjustingrod 12 has a T-shaped cross section. A width-adjustingseat 13 is telescoped on the width-adjustingrod 12. A corresponding T-shaped groove is formed in the width-adjustingseat 13. Ascrew hole 14 penetrating to the T-shaped groove is formed on the side plane of the width-adjustingseat 13. The width-adjustingseat 13 is locked on the width-adjustingrod 11 through aturn button 15. Inclined planes are formed at the facing ends of the two width-adjustingseats 13. Anarticle guiding rod 16 is joined at each of the two inclined planes so that the twoarticle guiding rods 16 are parallel. The outer side of each of thearticle guiding rods 16 slantingly joins the lower end of a height-adjustingrod 17 with the vertical plane thereof. The height-adjustingrod 17 also has a T-shaped cross section. A height-adjustingseat 18 is telescoped on the height-adjustingrod 17. The height-adjustingseat 18 is -shaped. The top plane of each of the height-adjustingseats 18 has a throughscrew hole 19. The height-adjustingseat 18 is locked on the height-adjustingrod 17 through aturn button 191. The inner side plane of each of the height-adjustingseats 18 joins a hooked plasticfilm guiding plate 192. - This prior art structure has been used for many years. Although its function is very good, its adjustment is not convenient. This prior art structure is joined against the surface of a machine table. The bottom plane of the machine table has a heating device. Guided-in plastic film is sleeved on an article and the both sides thereof are heated for packaging. For controlling the guiding-in of plastic film, the plastic film guiding device is provided to control the width and height of package. The length of package is also controlled using a cutting device at the rear end.
- Because the mechanisms of the prior art are individually fixed, the assembly is not easy after disassembled for maintenance or cleaning so that professional technicians are required. Therefore, the adjustment of the prior art structure is not convenient. All turn buttons must be loosened beforehand when setting each specification to perform the adjustment. Especially, because the installed position thereof is very near the heating device, the machine must be halt when the adjustment is performed. That is, heating must be stopped to facilitate manual adjustment. Moreover, the adjustment is separately performed at both sides, and the control is carried out through the help of scale rules at both sides. However, slight error still exists. Therefore, the run-in time and process are relatively lengthened. The present invention aims to resolve the above problems in the prior art.
- One object of the present invention is to provide a plastic film guiding device of a packaging machine. The guiding device is arranged in suspended way to reduce its contact with the surface of a machine table so that the present invention suffers less heat to facilitate the adjustment. Most importantly, the present invention has instant width-adjusting function, and can simultaneously perform identical adjustments to the widths of both sides. The adjustment is fast, and the positions of movement are exact. Moreover, fine adjustment of width can be performed at any time during the operation of the machine.
- The present invention comprises a frame, a screw rod, a walking block, a positioning rod, a pair of slanting rods, and a pair of slide bodies. The frame comprises two bottom plates, two side plates, a top plate, a front axle sheet, and a rear axle sheet. The front and rear axle sheets are installed at the centerline of the frame. The front axle sheet has a pivotally-joining hole, and the rear axle sheet has a screw hole. The screw rod penetrates the screw hole with the front end thereof joined in the pivotally-joining hole and the rear end thereof joining an adjuster. A screw hole penetrating from front to rear is formed in the walking block to be passed through by the screw rod so that the walking block can be led to move forwards or backwards by the screw rod. A transverse hole is formed at the bottom of the walking block. The positioning rod is threaded in the transverse hole to be fixed perpendicular to the screw rod. The inner end of the slanting rod is joined at the top plate, and the outer end thereof protrudes out forwards. The positioning rods are symmetrically arranged. Each slide body has a slide block and a guide block. Each slide block is telescoped in the slanting rod via a slide groove. The inner end of the slide block joins downwards the guide block so that the two guide blocks are parallel arranged. The guide block joins one end of a height-adjusting rod. The pair of guide blocks are led to move by the adjuster for controlling the guided-in width of plastic film and for successfully guiding in articles. The height-adjusting rod is joined on the outer side plane of the guide block and is slantingly forward and upward. A fixing block is telescoped on the height-adjusting rod. The fixing block has a slide way therein to be passed through and has a control turn button for adjustment. The outer end of the height-adjusting rod joins a hooked plastic film guiding plate. An adjustable hanging device is provided above the top plate.

- FIG. 3 is an exploded perspective view of the present invention;
- FIG. 4 is a top view of the present invention when not moved yet;
- FIG. 5 is an action position diagram of the present invention when already moved;
- FIG. 6 is a side view of the present invention when performing height adjustment; and
- FIG. 7 is a perspective view of the present invention with a hanging device attached thereon.
- As shown in FIGS.2 to 6, a plastic
film guiding device 2 of a packaging machine of the present invention comprises aframe 21, ascrew rod 22, awalking block 23, apositioning rod 24, a pair of slantingrods 28, and a pair ofslide bodies 25. Theframe 21 comprises twobottom plates 211, twoside plates 212, atop plate 213, afront axle sheet 214, and arear axle sheet 216. Thefront axle sheet 214 and therear axle sheet 216 are provided at the centerline of theframe 21. Thefront axle sheet 214 has a pivotally-joininghole 215, and therear axle sheet 216 has ascrew hole 217. - The
screw rod 22 penetrates thescrew hole 217 with the front end thereof joined in the pivotally-joininghole 215 and the rear end thereof joining an adjuster 218 (such as a manual wheel shown in the figure). Thescrew rod 22 is driven by theadjuster 218. - A
screw hole 231 penetrating from front to rear is formed in thewalking block 23 to be passed through by thescrew rod 22 so that the walkingblock 23 can be led to move forwards or backwards by thescrew rod 22. Atransverse hole 232 and abottom screw hole 234 are formed at lower part of the bottom of thewalking block 23. Thepositioning rod 24 is threaded in thetransverse hole 232 to be fixed perpendicular to thescrew rod 22. - As shown in the FIGS.2 to 6, the
positioning rod 24 can be a circular transverse rod passing through thetransverse hole 232, and is fixed in thewalking block 23 by locking astud 233 in thebottom screw hole 234 of thewalking block 23. The inner end of the slantingrod 28 is joined on thetop plate 213, and the outer end thereof protrudes out forwards. Thepositioning rods 28 are symmetrically arranged with respect to the centerline of theframe 21 to be approximately -shaped. - Each of the
slide bodies 25 has aslide block 251 and aguide block 254. Eachslide block 251 is telescoped in the slantingrod 28 via aslide groove 252. As shown in the FIGS. 2 to 6, the slantingrods 28 seem to be not connected to theslide groove 252. There are two ways to resolve this problem. The first way: a slide block of a linear bearing is formed on the periphery of the slanting rod, and the slide track of the linear bearing is fixedly provided in theslide groove 252, thereby forming a linear slide structure. The second way: theslide groove 252 forms a mouth-shaped passage, and theslide bodies 25 are directly hanged on the slantingrods 28. The inner end of theslide block 251 joins downwards theguide block 254 so that the twoguide blocks 254 of the twoslide bodies 25 are parallel arranged. Theguide block 254 joins one end of a height-adjustingrod 26. - As shown in the FIGS.2 to 6, the slide block is slightly triangular. The top end of the
guide block 254 is joined on the side plane of theslide block 251 by means of atriangular block 253. The inner side of the lower end of theguide block 254 joins an L-shapedguide plate 255. The outer end of the L-shapedguide plate 255 protrudes out forwards. The L-shapedguide plate 255 is used for controlling the guided-in width of the plastic film 4 and for successfully guiding in articles. - The height-adjusting
rod 26 is joined on the outer side plane of theguide block 254 and is slantingly forward and upward. A fixingblock 27 is telescoped on the height-adjustingrod 26. The fixingblock 27 has aslide way 271 therein to be passed through and has acontrol turn button 273 for locking and adjusting. The fixingblock 27 is covered by acover plate 272, which is locked on the fixingblock 27 with a plurality of small screws screwed in holes of thecover plate 272. Thecontrol turn button 273 also passes through a central hole of thecover plate 272 to be locked on the surface of the height-adjustingrod 26. The outer end of each height-adjustingrod 26 joins a hooked plasticfilm guiding plate 275. The plasticfilm guiding plate 275 is used for guiding in the plastic film 4. - Each height-adjusting
rod 26 hasscales 261 thereon. The fixingblock 27 moves upwards and downwards on the height-adjustingrod 26 to set the guided-in height of the plastic film 4. Ascale ruler 210 is provided on the side plane of the front section of thetop plate 213 for controlling the to and fro motion and the expanded size of theslide bodies 25 so as to become the control scales for width adjustment. - As shown in FIG. 6, when the fixing
block 27 is moved upwards (outwards) from a distance of length e to a distance of length f away from the bottom of thebottom plate 211, and also from a distance of length c to a distance of length d away from the front end of thebottom plate 211, the height adjustment of the guided-in plastic film is completed. - The present invention can also be hanging type. As shown in FIG. 7, a hanging
device 29 is provided above the top plate and is joined at the centerline of the frame. Thetop plate 213 has aslide groove 219. The two sides of ahorizontal part 291 of an L-shapedplate 290 are joined in theslide groove 219. The relationship between theslide groove 219 and the L-shapedplate 290 can be the relationship between a T-shaped groove and a raised edge or the relationship between similar structures. At least a fixingscrew 292 is provided above the L-shapedplate 290 to pass from a long hole of thehorizontal part 291 to the screw hole of thetop plate 213 so that not only the L-shapedplate 290 can join theguiding device 2, but also the for and aft position of the guidingdevice 2 can be adjusted. - The front end of a
vertical part 293 of the L-shapedplate 290 joins an adjustingblock 296. Thevertical part 293 has along hole 294. An adjustingscrew 295 passes through thelong hole 294 to lock the L-shapedplate 290 on the surface of the adjustingblock 296. The adjustingscrew 295 can be loosened for adjusting the height of the adjustingblock 296 so that the up and down height of the guidingdevice 2 of the present invention can be adjusted. Ascale ruler 35 can be provided on the side surface of thevertical part 293 of the L-shapedplate 290 for adjusting the height of the hangingdevice 29. - A through
groove 297 is formed in the adjustingblock 296 to be penetrated by a rod 298 (a circular rod or a square rod). Apositioning screw 30 on the top plane of the adjustingblock 296 is locked in thescrew hole 299 of the adjustingblock 296 for adjusting the left and right position of the guidingdevice 2 of the present invention. Ascale ruler 37 can be provided on therod 298, and ascale ruler 36 can be provided on the top side surface of the vertical part of the L-shapedplate 290 for adjusting the horizontal position of the hangingdevice 29. - The other end of the
rod 298 is joined on a side plane 3 of a machine table through an eared fixingseat 33. Therod 298 is locked on the machine table with a pair ofscrews 32 passing through holes of the eared fixingseat 33. Thereby, the present invention can be hanged above the surface of the machine table, showing a structure different from the prior art. - The present invention utilizes the turn of an adjuster to lead a pair of
slide bodies 25. Because a pair of slantingrods 28 is arranged as -shape, the slide bodies will generate synchronous left and right motion, i.e., simultaneous motion toward or away from each other. As shown in FIG. 5, solid lines show the position before adjustment, while dashed lines show the position after adjustment. The distance between the two L-shapedguiding plates 255 is b before adjustment, and the distance between them becomes a after adjustment. As shown in FIG. 5, the outer ends of the L-shapedguide plates 255 shrink from outer site to inner site. Thereby, the width control of the guidingdevice 2 becomes synchronous shrinkage or enlargement, and the adjustment can be performed whenever and wherever. In other words, instant adjustment can also be performed during the process. This is totally different from the prior art. Moreover, it is not necessary to adjust a pair of turn buttons as the prior art, and it is not necessary to halt the machine for adjustment. - Furthermore, a hanging device is added in the present invention to hang the
guiding device 2 high. This is totally different from the prior art, wherein the guiding device can only be installed on the surface of a machine table. Therefore, the heat suffered by the whole guiding device can be reduced so that width and height adjustment can be performed more conveniently. The present invention utilizes a pair of fixing blocks for height adjustment. Therefore, the present invention has better effects of guiding and adjustment for plastic film than the prior art. - Although the present invention has been described with reference to the preferred embodiments thereof, it will be understood that the invention is not limited to the details thereof. Various substitutions and modifications have been suggested in the foregoing description, and others will occur to those of ordinary skill in the art. Therefore, all such substitutions and modifications are intended to be embraced within the scope of the invention as defined in the appended claims.
