The specific embodiment
Referring to Fig. 1, present embodiment is to have adopted heat shrink films machine of the present utility model, comprises hot air circulation mechanism 1, connecting gear 2 and frame 3, and hot air circulation mechanism 1, frame 3 are prior art, do not describe in detail at this; Connecting gear is the chain-type transmission, comprise transmission chain 4, motor 5, drive the sprocket wheel 6 of chain movement, tension wheel 7, packed article support fixture 8 and chain support guide runner 9, motor 5 drives transmission chain 4 by sprocket wheel 6 and at the uniform velocity moves ahead, tension wheel 7 is used to regulate the elasticity of transmission chain 4, chain supports guide runner 9 and has the effect that guarantees packed article 14 smooth motions, packed article support fixture 8 is used to support packed article 14, the size of packed article support fixture 8 and packed article 14 sizes are complementary, and according to different packed article sizes packed article support fixture 8 are changed to guarantee packed article steadily setting in the process of passing through hot air circulation mechanism 1.Said structure also is a prior art, does not describe in detail at this.
Referring to Fig. 1, Fig. 2 and Fig. 4, the structure that the utility model is improved is as follows: the bindiny mechanism between packed article support fixture 8 and the transmission chain 4 is improved, between packing material support fixture 8 and transmission chain 4, be provided with gear 10, gear 10 is placed on the bearing, gear 10 can rotate with bearing, gear 10 is positioned at the packed article support fixture 8 times, is supporting packed article support fixture 8, and bearing is connected on the transmission chain 4; Simultaneously, side in the close hot air circulation mechanism of gear 10 is provided with monolateral tooth bar 11, the tooth of monolateral tooth bar 11 is towards gear 10, the length of monolateral tooth bar 11 is identical with the length of hot air circulation mechanism 1, initiating terminal and end at monolateral tooth bar 11 respectively are provided with a manual regulation button 12,13, manual regulation button 12,13 are installed on thread rod 14 respectively by screw thread fit, on 15, manual regulation button 12,13 are limited in the hole of monolateral tooth bar 11 perpendicular to monolateral tooth bar 11 and its inner, when turn manual regulation button 12,13 when mobile outwardly inwardly, drives monolateral tooth bar 11 corresponding moving and make it with gear 10 engagements or away from gear 10.
Referring to Fig. 2 and Fig. 3, regulate initiating terminal manual regulation button 12 and terminal manual regulation button 13, make on monolateral tooth bar 11 and the transmission chain 4 that is in the hot air circulation mechanism 1, the gear 10 under the packed article support fixture 8 mesh one by one, the angle α between gear 10 lines of centres on this moment monolateral tooth bar 11 and the transmission chain 4 is zero.When entering in the hot air circulation mechanism 1 under the importing effect of the packed article 14 that is coated with heat shrink films at packed article support fixture 8, because each gear 10 on monolateral tooth bar 11 and the transmission chain 4 meshes fully, hot air circulation mechanism 1 at the uniform velocity moves ahead packed article 14 at once and rotation from entering.
Referring to Fig. 4 and Fig. 5, regulate initiating terminal manual regulation button 12 and terminal manual regulation button 13, make the screw-in displacement of the screw-in displacement of initiating terminal manual regulation button 12 less than terminal manual regulation button 13, the angle α between gear 10 lines of centres on monolateral tooth bar 11 and the transmission chain 4 is between 0 °～30 ° at this moment.When entering in the hot air circulation mechanism 1 under the importing effect of the packed article 14 that is coated with heat shrink films at packed article support fixture 8, because the initiating terminal and the gear 10 of monolateral tooth bar 11 are in non-engagement state, therefore, the packed article 14 that is coated with heat shrink films only at the uniform velocity moves ahead with transmission chain 4 and can't rotation, move to monolateral tooth bar 11 when with gear 10 on the transmission chain 4 position engaged taking place up to the packed article 14 that is coated with heat shrink films, packed article 14 begins rotation when at the uniform velocity passing through hot air circulation mechanism 1 with transmission chain 4.
Concrete working process of the present utility model is as follows: when packed article is circle, two manual regulation buttons 12,13 all are transferred to outermost end, this moment, monolateral tooth bar 11 did not mesh fully with all gears 10, on the packed article support fixture 8 that packed article is inserted on the transmission chain 4, forward hot air circulation mechanism 1 moves ahead.Because packed article is circular, die hot blast that blows out from frame 3 both sides and the heat shrink films that is coated on circular packed article outside face respectively to the contact probability basically identical, each is basic identical to shrinkage degree for heat shrink films after being heated, so do not have the contraction bad phenomenon, so packed article does not need rotation yet.At last, the packed article of process shrink wrapping is deviate from from packed article support fixture 8, got final product through cooling again.
When packed article is shapes such as ellipse, oblong, manual modulation valve 12,13 is gone into to nearly gear 10 1 sidespins, and making the screw-in displacement of the screw-in displacement of initiating terminal manual regulation button 12 less than terminal manual regulation button 13, formation allows angle α between 0 °～30 ° between gear 10 lines of centres on monolateral tooth bar 11 and the transmission chain 4 at this moment.When the packed article that is coated with heat shrink films is inserted in packed article support fixture 8, the two sides on the plane, minor axis place that is parallel to the ellipticity packed article or the side, minor face place and the chain direction of transfer of oblong packed article are consistent.When entering hot air circulation mechanism 1 under the importing effect of the packed article 14 that is coated with heat shrink films at packed article support fixture 8, because the gear 10 on monolateral tooth bar 11 initiating terminals and the transmission chain 4 is in non-engagement state, the ellipticity packed article is parallel to that the hot blast that blows out in heat shrink films and the hot air circulation mechanism 1 on side, the minor face place outside face of the two sides on plane, ellipse short shaft place or oblong packed article is vertical contact also contraction in advance and finalize the design.When being coated with the packed article of the heat shrink films of pre-setting when having moved to monolateral tooth bar 11 with the intermeshing position of gear 10 beginnings, packed article rotates under the engagement of gear 10 and monolateral tooth bar 11, thereby the heat shrink films that is coated on the packed article outside face is heated evenly in hot air circulation mechanism 1.For guaranteeing good contractive effect, angle α is advisable to be not more than 20 °, specifically can regulate voluntarily according to packed article shape and the required contractive effect that reaches.If need not heat shrink films is shunk in advance, then regulate manual regulation button 12,13, the displacement that both are gone into to gear 10 1 sidespins equals its inside range, this moment, angle α was zero, each gear 10 on monolateral tooth bar 11 and the transmission chain 4 meshes fully, thereby packed article promptly begins rotation from entering hot air circulation mechanism.Packed article passes through hot air circulation mechanism 1 and finishes whole contraction process, and it is deviate from from packed article support fixture 8, gets final product through cooling again.
