Description

Technical Field

[0001] The utility model relates to the technical field of plastic film production, in particular to a novel bubble stabilizing frame. Background Art

[0002] The film blowing machine heats and melts plastic particles and then blows them into bubble films. The cylindrical bubble films are cooled, folded, printed, plastic-sealed, and punched to form packaging bags. During the cooling process, the bubble films blown out by the film blowing machine need to be stabilized by a bubble stabilizing mechanism. The traditional bubble stabilizing mechanism requires visual inspection and manual adjustment of each bubble stabilizing rod, which easily results in poor consistency between the adjusted bubble stabilizing path and the die head of the film blowing machine. The improved bubble stabilizing frame mostly drives multiple bubble stabilizing rods to rotate through a transmission chain, and then the positions of the bubble stabilizing rods of multiple bubble stabilizing frames can be adjusted, so that multiple bubble stabilizing rods can be used to match film bubbles of different diameters. However, the transmission chain will become loose and fall off when used for a long time, affecting the matching and connection effect of the transmission chain and the transmission gear, resulting in poor connection stability. In addition, the film bubble and the bubble stabilizing rod will directly contact and slide, which may cause damage to the film bubble. For this reason, we propose a new type of bubble stabilizing frame. Utility Model Content

[0024] Reference Figures 1 to 8 The present embodiment is a novel bubble stabilizing frame, comprising a support frame 100, a plurality of rotating rods 200, a plurality of bubble stabilizing rods 300, and a transmission mechanism 400. The transmission mechanism 400 drives the plurality of rotating rods 200 to rotate and then drives the plurality of bubble stabilizing rods 300 to rotate.

[0025] Specifically, the support frame 100 includes an upper support block 101 and a lower support block 102 of an annular structure, and a plurality of connecting plates 103 arranged between the bottom end of the upper support block 101 and the top end of the lower support block 102. A slide groove 102a connected to the outer side of the lower support block 102 is circumferentially opened in the middle of the lower support block 102 with the center of the circle of the lower support block 102 as the center point. The cross section of the slide groove 102a is convex. The upper support block 101 is located directly above the lower support block 102. A plurality of first bearing seats 104 are arranged at equal angles at the bottom end of the upper support block 101. A plurality of second bearing seats 105 are arranged at the top end of the lower support block 102 at positions corresponding to the plurality of first bearing seats 104.

[0026] Preferably, there are multiple rotating rods 200, and both ends of the rotating rods 200 are respectively fixed in the inner rings of the first bearing seat 104 and the corresponding second bearing seat 105, and one end of the rotating rod 200 located in the inner ring of the second bearing seat 105 passes downward through the lower support block 102 into the slide groove 102a, and one end of the rotating rod 200 located in the slide groove 102a is provided with a gear 201;

[0027] Since both ends of the rotating rod 200 are respectively fixed in the inner rings of the first bearing seat 104 and the second bearing seat 105 , the gear 201 at the bottom end of the rotating rod 200 can rotate after receiving force.

[0028] Preferably, there are multiple bubble stabilizing rods 300, one end of each bubble stabilizing rod 300 is vertically connected to the rotating rod 200, multiple bubble stabilizing rods 300 are arranged at intervals on the outer wall of each rotating rod 200, the bubble stabilizing rods 300 on the multiple rotating rods 200 are cross-distributed with each other, and the projections of the bubble stabilizing rods 300 on the multiple rotating rods 200 on the horizontal plane form a polygonal channel;

[0029] When multiple rotating rods 200 are rotated at the same time, since the bubble stabilizing rods 300 on the multiple rotating rods 200 are cross-distributed with each other, the bubble stabilizing rods 300 on the multiple rotating rods 200 are close to each other in the horizontal projection direction and form a polygonal channel. The membrane bubble passes through the polygonal channel surrounded by the multiple bubble stabilizing rods 300 to maintain the shape of the membrane bubble.

[0030] Preferably, the transmission mechanism 400 includes an annular bar 401 arranged in the slide groove 102a, and the end surface of the annular bar 401 facing the gear 201 is circumferentially provided with a plurality of first teeth 402 meshing with the gear 201, and the top of the annular bar 401 is circumferentially provided with a plurality of second teeth 403, and the top of the lower support block 102 is respectively provided with a rotating member 404 and a locking member 405.

[0031] When the annular strip 401 in the slide groove 102a rotates under force, the multiple first teeth 402 on the annular strip 401 drive the gear 201 to rotate, and then drive the multiple rotating rods 200 to rotate. The bubble stabilizing rods 300 on the multiple rotating rods 200 approach each other in the horizontal projection direction and form a polygonal channel.

[0032] Preferably, a plurality of first ball grooves 102a - 1 are circumferentially formed on the bottom wall of the slide groove 102a , and first balls 102a - 2 are movably disposed in the first ball grooves 102a - 1 , and the first balls 102a - 2 abut against the bottom end of the annular strip 401 .

[0033] Since the annular strip 401 is disposed in the slide groove 102a, when the annular strip 401 is rotated under force, the bottom end of the annular strip 401 abuts against the first ball 102a-2, which can reduce the friction force of the annular strip 401 when rotating.

[0034] Preferably, a plurality of second ball grooves 102a - 3 are circumferentially opened on the inner wall of one side of the slide groove 102a facing the annular strip 401 , and second balls 102a - 4 are movably arranged in the second ball grooves 102a - 3 , and the plurality of second balls 102a - 4 are in contact with the side wall of the annular strip 401 .

[0035] Since the annular strip 401 is disposed in the slide groove 102a, when the annular strip 401 is rotated under force, one side of the annular strip 401 contacts the second ball 102a-4 to reduce the friction force of the annular strip 401 during rotation, making the annular strip 401 more labor-saving during rotation.

[0036] Preferably, the rotating member 404 includes a support plate 404a arranged at the top of the lower support block 102, a third bearing seat 404b is arranged in the middle of the support plate 404a, a rotating shaft 404c is arranged in the inner ring of the third bearing seat 404b, a bevel gear 404d meshing with the multiple second teeth 403 at the top of the annular strip 401 is arranged at one end of the rotating shaft 404c, a handwheel 404e is arranged at the other end of the rotating shaft 404c, and a handle 404e-1 is arranged on one side of the handwheel 404e.

[0037] When the hand wheel 404e is rotated by the handle 404e-1, the rotating shaft 404c can be driven to rotate. When the rotating shaft 404c rotates, the bevel gear 404d whose end is meshed with the plurality of second teeth 403 can be driven to rotate. The rotation of the bevel gear 404d can drive the rotation of the annular bar 401, and the rotation position of the annular bar 401 can be more accurately controlled by rotating the hand wheel 404e by the handle 404e-1.

[0038] Preferably, the locking member 405 includes a clamping tube 405a arranged at the connection point between the top end of the lower support block 102 and the slide groove 102a, the clamping tube 405a is a hollow structure with an opening at the bottom, a lifting rod 405b is inserted in the clamping tube 405a, a clamping block 405c is arranged at the bottom end of the lifting rod 405b, a plurality of clamping teeth 405d are arranged at the bottom end of the clamping block 405c, a spring 405e is sleeved on the outer wall of the lifting rod 405b, and a lifting handle 405f is arranged at the top end of the lifting rod 405b.

[0039] Since the clamping tube 405a is arranged at the connection point between the top of the lower support block 102 and the slide groove 102a, after adjusting the rotation position of the annular strip 401, the lifting handle 405f is released, and the lifting rod 405b moves downward under the elastic force of the spring 405e until the multiple clamping teeth 405d at the bottom end of the clamping block 405c clamp the multiple second teeth 403 at the top end of the annular strip 401 inside the slide groove 102a, so that the position of the annular strip 401 is fixed, preventing the bubble stabilizing rod 300 from being subjected to the thrust of the membrane bubble and thereby driving the rotation of the rotating rod 200 and the annular strip 401.

[0040] Preferably, the bubble stabilizing rod 300 is provided with a roller 301 on the outside, and a plurality of third ball grooves 302 are evenly distributed on the outer wall of the bubble stabilizing rod 300 in a circumferential direction. A third ball 303 is movably arranged in the third ball groove 302, and the third ball 303 is fitted with the inner wall of the roller 301. A threaded hole 304 is provided at the end of the bubble stabilizing rod 300, and a threaded column 305 is threadedly connected to the threaded hole 304, and a baffle 306 is provided on one side of the threaded column 305.

[0041] When the film bubble contacts the roller 301 and is pulled upward, the film bubble drives the roller 301 to rotate, thereby reducing the friction between the film bubble and the roller 301 and thus reducing the situation where the film bubble is damaged by excessive friction. Since the third ball 303 in the third ball groove 302 on the outer wall of the bubble stabilizing rod 300 fits with the inner wall of the roller 301, the roller 301 does not need to be subjected to too much force to rotate, and the baffle 306 can prevent the roller 301 from detaching from the outside of the bubble stabilizing rod 300.

[0042] Working principle: When the size of the polygonal channel surrounded by the multiple bubble-stabilizing rods 300 needs to be adjusted according to the size of the film bubble, lift the lifting handle 405f, and the lifting rod 405b drives the multiple engaging teeth 405d at the bottom of the engaging block 405c to disengage the multiple second teeth 403 at the top of the annular strip 401. When the hand wheel 404e is rotated by the handle 404e-1, the rotating shaft 404c can be driven to rotate. When the rotating shaft 404c rotates, it drives the bevel gear 404d whose end is meshed with the multiple second teeth 403 at the top of the annular strip 401 to rotate. The rotation of the bevel gear 404d can drive the rotation of the annular strip 401 through the multiple second teeth 403 When the annular strip 401 is rotated under force, the multiple first teeth 402 on the annular strip 401 drive the gear 201 to rotate, thereby driving the rotation of the multiple rotating rods 200, and the bubble stabilizing rods 300 on the multiple rotating rods 200 are close to each other in the horizontal projection direction and form a polygonal channel. Since the larger the rotation angle of the annular strip 401 is, the larger the rotation angle of the multiple rotating rods 200 is, the smaller the size of the polygonal channel formed by the bubble stabilizing rods 300 on the multiple rotating rods 200 is. Therefore, the number of rotations of the hand wheel 404e-1 is accurately controlled according to the diameter of the film bubble, until the polygonal channel surrounded by the bubble stabilizing rods 300 is After the size of the channel is adjusted to the target size, the lifting handle 405f is released, and the lifting rod 405b moves downward under the elastic force of the spring 405e until the multiple engaging teeth 405d at the bottom of the engaging block 405c engage the multiple second teeth 403 at the top of the annular strip 401 inside the slide groove 102a, so that the position of the annular strip 401 is fixed, preventing the bubble stabilizing rod 300 from being pushed by the bubble and then driving the rotation rod 200 and the annular strip 401 to rotate. Since the annular strip 401 is arranged in the slide groove 102a, when the annular strip 401 is rotated under force, the bottom end and one side of the annular strip 401 are respectively engaged with the first ball 102a-2 and The second ball 102a-4 can reduce the friction effect on the annular strip 401 during rotation, making the annular strip 401 more labor-saving to rotate. The bubble contacts the roller 301 outside the bubble stabilizing rod 300 and when the bubble is pulled upward, the bubble drives the roller 301 to rotate, thereby reducing the friction between the bubble and the roller 301 and thus reducing the situation where the bubble is damaged by excessive friction. Since the third ball 303 in the third ball groove 302 on the outer wall of the bubble stabilizing rod 300 fits with the inner wall of the roller 301, the roller 301 does not need to be subjected to too much force to rotate, and the baffle 306 can prevent the roller 301 from detaching from the outside of the bubble stabilizing rod 300.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
