Description

Technical Field

[0001] The utility model belongs to the technical field of composite film production equipment, and particularly relates to an alignment mechanism of a dry laminator. Background Art

[0002] A dry laminator is a machine that bonds different plastic films together through a dry lamination process. That is, after applying glue to the surface of the plastic film, the solvent in the glue solution is fully dried by heating and exhausting, and then lamination is carried out. In view of the fact that during the lamination operation of plastic films, the films are prone to phenomena such as dislocation and offset, seriously affecting the subsequent lamination effect and reducing the finished product rate. Therefore, a structure for adjusting the position of the plastic film needs to be provided on the laminator, so as to continuously adjust the relative position between the two plastic films and the relative position between the plastic film and the feed inlet of the laminator, and avoid the generation of defective laminated products caused by dislocation and offset.

[0003] Most of the alignment mechanisms proposed in the prior art can only adjust the relative position of the upper and lower plastic films at the same time. When the upper and lower plastic films both deviate to one side, their positions cannot be adjusted, ultimately affecting the finished product rate of lamination. Content of the Utility Model

[0004] The purpose of the utility model is to provide an alignment mechanism of a dry laminator that can not only adjust the relative position of the upper and lower plastic films at the same time, but also adjust the positions of the two plastic films as a whole, so as to solve the problems raised in the above background art.

[0005] To achieve the above technical purpose, the technical solution of the utility model is as follows:

[0006] An alignment mechanism of a dry laminator includes a first lead screw and a second lead screw arranged in parallel with the first lead screw. The two ends of the first lead screw are rotatably connected to a first baffle and a second baffle. The bottoms of the first baffle and the second baffle are both fixed on a base. The first lead screw is threadedly connected to a third baffle. The third baffle is located between the first baffle and the second baffle and is arranged parallel to the first baffle and the second baffle. The second lead screw is connected to the third baffle through a bearing;

[0007] The second lead screw is respectively connected to a first slider and a second slider through two threads with opposite helix directions. The second lead screw is slidably connected to the first baffle and the second baffle. The first lead screw is slidably connected to the first slider and the second slider.

[0008] As a further improvement, an upper bending plate is fixedly connected to the top surface of the first slider, and a lower bending plate is fixedly connected to the bottom surface of the second slider. The lower bending plate is connected to the base through a slide rail. Both the upper bending plate and the lower bending plate are U-shaped. The opening direction of the upper bending plate faces upward, and the opening direction of the lower bending plate faces downward. Two guiding roller shafts are rotatably arranged inside both the upper bending plate and the lower bending plate. The upper bending plate and the lower bending plate are respectively used for conveying two layers of plastic films.

[0009] As a further improvement, both the upper bending plate and the lower bending plate include a bottom plate and two side plates.

The guiding roller shafts arranged closer to the bottom plate inside the upper bending plate and the lower bending plate are correspondingly arranged, and the guiding roller shafts arranged closer to the opening are correspondingly arranged.

[0010] As a further improvement, a locking structure is provided at one end of the first lead screw. The locking structure includes a snap ring. The snap ring is fixedly sleeved on the first lead screw. A locking hole is formed by a radial depression on the circumferential side surface of the snap ring. A plurality of locking holes are evenly distributed along the circumference of the snap ring.

[0011] As a further improvement, a lock body is sleeved outside the snap ring. The lock body is fixedly connected to the outer side of the second baffle.

The first groove and the second groove are perpendicular to each other, and the depth of the second groove is greater than that of the first groove.

[0012] As a further improvement, an installation hole is vertically provided downward along the axial direction inside the boss. A fourth baffle is fixedly provided at the top of the installation hole. A guide rod is slidably arranged up and down inside the installation hole. The top end of the guide rod penetrates through the fourth baffle and is fixedly provided with a cylindrical pull ring. The diameter of the pull ring matches the sizes of the first groove and the second groove.

[0013] As a further improvement, a circular block is fixedly provided on the outer circumferential surface of the guide rod near the bottom. A spring is sleeved outside the guide rod. One end of the spring abuts against the fourth baffle, and the other end of the spring abuts against the block.

[0025] Such as Figure 1-6As shown in the figure, an alignment mechanism of a dry laminator includes a first lead screw 1 and a second lead screw 2 arranged in parallel with the first lead screw 1. Both ends of the first lead screw 1 are rotatably connected to a first baffle 3 and a second baffle 4. The bottoms of the first baffle 3 and the second baffle 4 are fixedly connected to a base 5. A third baffle 6 is threadedly connected to the first lead screw 1. The third baffle 6 is located between the first baffle 3 and the second baffle 4 and is arranged in parallel with the first baffle 3 and the second baffle 4. The second lead screw 2 is connected to the third baffle 6 through a bearing. When the first lead screw 1 rotates, it drives the third baffle 6 and the second lead screw 2 to move axially.

[0026] Specifically, the first lead screw 1 can be connected to the first baffle 3 and the second baffle 4 through a bearing, or can be connected to the first baffle 3 and the second baffle 4 through other structures, as long as the rotational connection between the first lead screw 1 and the first baffle 3 and the second baffle 4 can be achieved.

[0027] Two sections of threads with opposite helix directions are provided on the second lead screw 2, which are threadedly connected to a first slider 7 and a second slider 8 respectively. Through holes for slidably connecting with the second lead screw 2 are provided on both the first baffle 3 and the second baffle 4, and through holes for slidably connecting with the first lead screw 1 are provided on both the first slider 7 and the second slider 8. When the second lead screw 2 rotates, the first slider 7 and the second slider 8 move in opposite directions.

[0028] In this embodiment, an upper bending plate 9 is fixedly connected to the top surface of the first slider 7, and a lower bending plate 10 is fixedly connected to the bottom surface of the second slider 8. The lower bending plate 10 is connected to the base 5 through a slide rail. When the first slider 7 and the second slider 8 move, they drive the upper bending plate 9 and the lower bending plate 10 to move respectively.

[0029] In this embodiment, both the upper bending plate 9 and the lower bending plate 10 are U-shaped, including a bottom plate 1001 and two side plates 1002. The bottom plates 1001 of the upper bending plate 9 and the lower bending plate 10 are fixedly connected to the top surface of the first slider 7 and the bottom surface of the second slider 8 respectively. The two side plates 1002 are fixedly connected to both ends of the bottom plate 1001 respectively. The opening direction of the upper bending plate 9 is upward, and the opening direction of the lower bending plate 10 is downward.

[0030] Two guiding roller shafts 1003 are rotatably connected between the two side plates 1002 of the upper bending plate 9 and the lower bending plate 10. The two guiding roller shafts 1003 are arranged in parallel along the diagonal of the side plate 1002. The guiding roller shafts 1003 close to the bottom plate 1001 in the upper bending plate 9 and the lower bending plate 10 are arranged correspondingly, and the guiding roller shafts 1003 close to the opening in the upper bending plate 9 and the lower bending plate 10 are arranged correspondingly, which are used to guide the plastic film 1004 to be laminated.

[0031] In this embodiment, a locking structure 11 is provided at one end of the first lead screw 1 for restricting the rotation of the first lead screw 1. The locking structure 11 includes a snap ring 1101. The snap ring 1101 is fixedly sleeved on the first lead screw 1. A locking hole 1102 is formed by a radial depression on the circumferential side surface of the snap ring 1101. There are multiple locking holes 1102 on the side wall of the snap ring 1101, and the multiple locking holes 1102 are evenly distributed along the circumference of the snap ring 1101.

[0032] In this embodiment, a lock body 1103 is sleeved outside the snap ring 1101. The lock body 1103 is fixedly connected to the outside of the second baffle 4. A cylindrical boss 1104 is fixedly provided on the upper surface of the lock body 1103. A first groove 1105 and a second groove 1106 are provided along the radial direction on the upper end surface of the boss 1104. The first groove 1105 and the second groove 1106 are perpendicular to each other, and the depth of the second groove 1106 is greater than that of the first groove 1105.

[0033] In this embodiment, an installation hole is vertically provided downward along the axial direction inside the boss 1104. A fourth baffle 1107 is fixedly provided at the top of the installation hole. A guide rod 1108 is slidably provided in the installation hole. A semi-circular pull ring 1109 is provided at the top end of the guide rod 1108. The diameter of the pull ring 1109 matches the sizes of the first groove 1105 and the second groove 1106. The bottom of the guide rod 1108 extends into one of the locking holes 1102;

[0034] A circular stopper 1110 is fixedly provided at a position near the bottom outside the guide rod 1108. The circular stopper 1110 is slidably connected to the side wall of the installation hole. The guide rod 1108 can slide up and down along the axial direction of the installation hole. A spring 1111 is sleeved outside the guide rod 1108. One end of the spring 1111 abuts against the fourth baffle 1107, and the other end of the spring 1111 abuts against the stopper 1110;

[0035] When the pull ring 1109 is rotated and lifted at the same time, the pull ring 1109 cooperates with the first groove 1105; when the pull ring 1109 is rotated and released at the same time, the pull ring 1109 cooperates with the second groove 1106.

[0036] Preferably, handles are provided at the ends of both the first lead screw 1 and the second lead screw 2.

[0037] When this embodiment is in use, in accordance with Figure 3The connection method shown connects the plastic film 1004 to the alignment mechanism. When there is a relative misalignment between the upper and lower layers of the plastic film 1004, rotate the pull ring 1109 of the locking structure 11 so that it cooperates with the second groove 1106. At this time, the bottom of the guide rod 1108 is located in one of the locking holes 1102, and the first lead screw 1 cannot rotate freely. Rotate the handle of the second lead screw 2. Since the thread directions of the two sections of the second lead screw 2 are opposite, the first slider 7 and the second slider 8 move in opposite directions. Thus, the positions of the upper bending plate 9, the lower bending plate 10, and their respective corresponding guide roller shafts 1003 can be driven to adjust until the upper and lower layers of the plastic film 1004 are aligned.

[0038] When the upper and lower layers of the plastic film 1004 are overall biased to one side, pull up and rotate the pull ring 1109 of the locking structure 11 so that it cooperates with the first groove 1105. At this time, the bottom of the guide rod 1108 disengages from the locking hole 1102, and the first lead screw 1 can rotate freely. Rotate the handle of the first lead screw 1 to drive the third baffle 6, the second lead screw 2, and the first slider 7 and the second slider 8 on the second lead screw 2 to move synchronously, and then drive the upper bending plate 9, the lower bending plate 10, and their respective corresponding guide roller shafts 1003 to move synchronously until the upper and lower layers of the plastic film 1004 are moved to the appropriate positions.

[0039] The specific embodiments of the present invention described above do not constitute a limitation on the protection scope of the present invention. Any other corresponding changes and deformations made according to the technical concept of the present invention should be included in the protection scope of the claims of the present invention.
