Abstract
Description
Technical Field
[0001] This utility model relates to a laminating machine, and in particular to a structure for detecting the humidity of an adhesive coating. Background Technology
[0002] Lamination is typically performed by a laminating machine, which bonds two or more layers of composite materials such as films or fabrics together using adhesive. Adhesive is applied to one layer of the composite material using an adhesive roller, forming an adhesive coating. Guided and compressed by the roller assembly, another layer of the composite material is then applied over the previous layer. Therefore, the adhesive coating is a crucial component in connecting the two composite layers, and the moisture content of the adhesive coating is a key factor affecting the lamination effect.
[0003] Currently, a humidity meter is typically installed on the frame of the laminating machine to measure the humidity of the adhesive coating on composite materials such as films and fabrics before lamination. If many measurements are outside the set range, the laminating machine is paused for further processing, especially at the glue roller position. However, this current method of measuring adhesive coating humidity has several drawbacks: composite materials such as films and fabrics are relatively wide, and the humidity meter only measures fixed locations, making it prone to omissions and failing to detect problems promptly. Utility Model Content
[0004] This application provides a structure for detecting the humidity of an adhesive coating, which can solve the problems mentioned in the background art.
[0005] This application provides a structure for detecting the humidity of an adhesive coating, comprising:
[0006] Connector;
[0007] Both stops are fixedly connected to the connecting frame and can be adjusted to a fixed position on the connecting frame along the first horizontal direction;
[0008] A reciprocating screw module is mounted on a connecting frame, and its mounting part moves back and forth between two stops along a first direction.
[0009] Humidity tester, installed in the installation section.
[0010] In some embodiments, a rack and pinion mechanism is provided between the stop block and the connecting frame, the rack and pinion mechanism being used to drive the stop block to move by the rotation of the gear.
[0011] In some embodiments, a limiting member is provided on the stop to restrict the movement of the stop, thereby limiting the rotation of the gear relative to the stop and thus restricting the movement of the stop.
[0012] In some embodiments, the shaft corresponding to the gear is hollow and has internal threads, and the stop has a threaded hole; the limiting member is a first screw, which is threaded to the through hole and can enter / exit the threaded hole.
[0013] In some embodiments, an adjustment mechanism is also provided between the mounting part and the humidity tester; the adjustment mechanism is used to adjust the distance between the humidity tester and the connecting frame.
[0014] In some embodiments, the adjustment mechanism includes: a first frame fixedly connected to the mounting portion, a second frame fixedly connected to the humidity tester and extending and retracting from the first frame, a slider slidably connected to the first frame, a second screw for driving the slider to move, a first connecting bar hinged between the slider and the first frame, and a second connecting bar hinged between the slider and the second frame.
[0015] In summary, this application discloses a humidity detection structure for an adhesive coating, comprising: a connecting frame, two stops, a reciprocating screw module, and a humidity meter. The detection structure is installed on the frame of a laminating machine. The positions of the two stops are adjusted according to the width of the composite material such as film or fabric. After the film or fabric is coated with adhesive by the glue roller, it passes through the detection structure before lamination, where the humidity of the adhesive coating is detected by the humidity meter. During this detection process, the reciprocating screw module slowly moves the humidity meter back and forth (a multi-stage planetary gear reducer can be installed between the motor and the reciprocating screw), measuring the adhesive coating at different locations. When many measurement data are outside the set appropriate range, the laminating machine is paused for further processing, especially at the glue roller position. The advantages include: the ability to measure the adhesive coating at different locations, and the ability to quickly and conveniently adapt to composite materials such as films and fabrics of varying widths.

[0032] Please see Figure 1 and Figure 2 A humidity detection structure for an adhesive coating includes: a connecting frame 1, two stops 2, a reciprocating screw module 3, and a humidity tester 4.
[0033] The connecting frame 1 is used to mount the detection structure to the frame of the composite machine. More specifically, extended connecting legs 1a can be fixed on both sides of the top of the connecting frame 1.
[0034] Both stop blocks 2 are fixedly connected to the connecting frame 1 and can be adjusted to a fixed position on the connecting frame 1 along a horizontal first direction. That is, both stop blocks 2 can move relative to the connecting frame 1 in the first direction. A limiting member 2a is provided between the stop blocks 2 and the connecting frame 1 to restrict the movement of the stop blocks 2, and this limiting member 2a can be released from restricting the movement of the stop blocks 2. More specifically, a linear guide rail can be used between the stop blocks 2 and the connecting frame 1 to achieve movement in the first direction.
[0035] Please participate Figure 2 and Figure 3 In some embodiments, a gear 6 and rack 5 mechanism is provided between the stop block 2 and the connecting frame 1. More specifically, the rack 5 is fixedly connected to the connecting frame 1, and the gear 6 is rotatably connected to the side of the stop block 2 away from the connecting frame 1, passing through the through slot of the stop block 2 and meshing with the rack 5. The gear 6 and rack 5 mechanism is used to drive the stop block 2 to move by rotating the gear 6.
[0036] After the detection structure is installed on the frame of the laminating machine, its height is relatively high, making it inconvenient to manually move the stop block 2 directly, and it is also difficult to control the distance the stop block 2 moves. By adding a gear 6 and rack 5 mechanism, the shaft 6a corresponding to the gear 6 (either the gear 6 is fixedly connected to the shaft 6a, or the gear 6 and the shaft 6a are integrated) extends downwards, making it easier to manually rotate, thereby driving the stop block 2 to move, and also making it easier to control the distance the stop block 2 moves.
[0037] In some embodiments, the limiting member 2a may be a fastener consisting of a bolt and a nut. A portion of the stop 2 is fitted to the connecting frame 1, and this portion of the stop 2 also has a through hole for threaded connection of the bolt. The connecting frame 1 has a convex groove along a first direction, the nut is located within the wider portion of the convex groove and is restricted from rotation, and the bolt enters the convex groove and is threaded onto the nut.
[0038] In some embodiments, a limiting member 2a is disposed on the stop 2 to limit the rotation of the gear 6 relative to the stop 2, thereby limiting the movement of the stop 2.
[0039] Please participate Figure 3 , Figure 4 and Figure 5 In some embodiments, the shaft 6a corresponding to gear 6 is hollow and has internal threads. More specifically, for ease of machining, the internal thread may only be a section of suitable length at one end of shaft 6a. The stop 2 has a threaded hole. More specifically, a connector 2b with the threaded hole may be fixedly connected to the stop 2. The limiting member 2a is a first screw, threaded into the through hole, and can enter / exit the threaded hole.
[0040] Compared to using fasteners as limiting elements 2a, the first screw extends downward through the shaft 6a, allowing for easier manual rotation. When it is necessary to restrict the movement of the stop 2, hold the handwheel on the shaft 6a with one hand to restrict its rotation, and rotate the first screw with the other hand to screw it into the threaded hole. When it is necessary to release the restriction on the movement of the stop 2, hold the handwheel on the shaft 6a with one hand to restrict its rotation, and rotate the first screw with the other hand to screw it out of the threaded hole.
[0041] The reciprocating screw module 3 is mounted on the connecting frame 1. More specifically, the reciprocating screw module 3 includes: a housing for mounting to the connecting frame 1; a mounting part 3a slidably connected to the housing in a first direction and fitted with a screw nut; a reciprocating screw rotatably connected to the housing and threadedly connected to the screw nut; and a motor for driving the reciprocating screw to rotate. The mounting part 3a moves back and forth between two stops 2 in the first direction. More specifically, the two stops 2 are Ω-shaped with notches through which the reciprocating screw module 3 passes. When the reciprocating screw rotates, it drives the mounting part 3a to move. When the mounting part 3a encounters a stop 2 and is blocked, it moves in the opposite direction.
[0042] Please participate Figure 1 The humidity tester 4 is installed in the mounting section 3a.
[0043] The detection structure is installed on the frame of the laminating machine. The positions of the two stops 2 are adjusted according to the width of the composite material such as film or fabric. After the film or fabric is coated with adhesive by the glue roller, it passes through the detection structure before lamination, where a humidity tester 4 measures the humidity of the adhesive coating. During this detection process, the reciprocating screw module 3 moves the humidity tester 4 slowly back and forth (a multi-stage planetary gear 6 reduction gearbox can be installed between the motor and the reciprocating screw) to measure the adhesive coating at different locations. When many of the measured data are outside the set appropriate range, the laminating machine is paused for further processing, especially at the glue roller position.
[0044] Please participate Figure 6 In some embodiments, an adjustment mechanism 7 is also provided between the mounting part 3a and the humidity tester 4. The adjustment mechanism 7 is used to adjust the distance between the humidity tester 4 and the connecting frame 1.
[0045] The detection structure is installed on the frame of the laminator. Depending on the specific laminator model and installation location, the distance between the humidity tester 4 and the adhesive coating is adjusted by the adjustment mechanism 7 to ensure the measurement results.
[0046] Please participate Figure 6In some embodiments, the adjustment mechanism 7 includes: a first frame 7a, a second frame 7b, a slider 7c, a second screw 7d, a first connecting bar 7e, and a second connecting bar 7f. The first frame 7a is fixedly connected to the mounting part 3a. The second frame 7b is used for mounting the humidity tester 4 and is also telescopically connected to the first frame 7a. More specifically, telescopic bars can be provided at the four corners of the first frame 7a and the four corners of the second frame 7b. The slider 7c is slidably connected to the first frame 7a. More specifically, the first frame 7a has an extension portion extending between the two lower telescopic bars, which is slidably connected to the extension portion via an optical axis 6a and a linear bearing. The second screw 7d is used to drive the slider 7c to move. More specifically, the upper end of the second screw 7d is stepped, the bottom surface of the slider 7c is provided with a T-shaped groove for the upper end of the second screw 7d to enter, and the extension portion is fixedly connected to a matching screw nut. The first connecting bar 7e is hinged between the slider 7c and the first frame 7a. The second connecting bar 7f is hinged between the slider 7c and the second frame 7b.
[0047] The second screw 7d extends downward through the shaft 6a corresponding to the gear 6, and can be easily rotated manually.
