Description

Technical Field

[0001] The present invention relates to the technical field of double-sided adhesive tape production equipment, in particular to automated production equipment for double-sided adhesive tape. Background Art

[0002] The main functions of double-sided tape include bonding, fixing, insulation, protection, and sealing. Specifically, double-sided tape can be used in various scenarios, including industrial manufacturing, home use, logistics and transportation, construction industry, electronics industry, etc. The production process of double-sided tape mainly includes the following steps:

[0003] 1. Substrate preparation: Double-sided tapes are usually made of paper, cloth, or plastic film. These substrates need to be cleaned and treated to ensure a clean, flat surface for subsequent adhesive application.

[0004] 2. Coating process:

[0005] Transfer coating: The adhesive is applied to the substrate, oven-dried, and then laminated to the composite material to transfer the adhesive. This method is suitable for double-sided tapes, single-sided label tapes, and foam-based tapes. Its characteristic is that the film thickness is uniform, and the total thickness of the tape is mainly determined by the thickness deviation of the composite material.

[0006] Direct coating: The adhesive is applied directly to the substrate and then rolled up. This method is suitable for packaging tapes and removable tapes. Its characteristic is that the adhesive easily penetrates the interior of the substrate and has good adhesion.

[0007] 3. Drying process: After application, the adhesive needs to be dried in an oven to evaporate the moisture and solvent, forming a dry film. Temperature and time must be controlled during the drying process to prevent premature hardening of the surface film, which would affect the volatilization of the internal solvent. The drying effect depends primarily on heat transfer, so the circulation of hot air in the oven is crucial.

[0008] 4. Winding: The dried tape needs to be wound. The winding part design needs to consider tension control to reduce the tension drop trend, overcome the air ingress when winding is too loose and the tape damage when winding is too tight;

[0009] 5. Finished product processing: Finally, the dried and rolled double-sided tape is cut, packaged, and finally becomes a finished product.

[0010] Existing double-sided tape production equipment has the following defects:

[0011] 1. Chinese patent CN218893272U discloses a double-sided tape die-cutting production protection device. During the double-sided tape laminating process, two air-expansion shafts are used to respectively fix two masterbatch materials. However, the two air-expansion shafts are connected to different motors. When one motor fails, the two air-expansion shafts rotate at different speeds. The different speeds of the air-expansion shafts cause the masterbatch winding speeds to differ. In this case, the two sets of masterbatch films will fold or even tangle. The folded and tangled masterbatch materials generate waste, resulting in material waste and production losses.

[0012] 2. In a double-sided tape preparation device and method disclosed in Chinese patent CN114851541B, during the loading process, two sets of masterbatch are directly clamped on the outer ends of the guide rollers. This makes it difficult to align the edges of the masterbatch, resulting in a large amount of waste at the edges of the double-sided tape after lamination, thus leading to masterbatch waste.

[0013] 3. Chinese patent CN218018722U discloses an inner roll cutting device for producing and processing double-sided tape. A single cutting device is used to cut the double-sided tape on the inner roll and the outer end. However, the position of the cutting device needs to be adjusted each time cutting, requiring multiple cutting operations, resulting in a slow cutting speed. At the same time, the cutting device requires precise measurement, which reduces the efficiency of slitting the double-sided tape.

DETAILED DESCRIPTION

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] Example 1:

[0039] See also Figure 1-4 , an automated production equipment for double-sided adhesive tape, including a base frame 1, a first side plate 2 is fixedly connected to the top side of the base frame 1, a feeding air inflation shaft 3 and a winding air inflation shaft 4 are provided on the inner side of the first side plate 2, a mounting leaf 5 is fixedly connected to the inner side of the first side plate 2, and a synchronous material retracting and unreeling mechanism 6 is provided on the inner and outer sides of the first side plate 2, the synchronous material retracting and unreeling mechanism 6 includes a cavity inner side plate 601 fixedly connected to the outer end of the mounting leaf 5, the inner part of the cavity inner side plate 601 is rotatably connected to a driven gear 602, the inner part of the cavity inner side plate 601 and the outer end of the driven gear 602 are both provided with a first pulley 603, the first pulley 603 is fixedly connected to the feeding air inflation shaft 3, a first connecting belt 604 is sleeved between the two first pulleys 603, the inner part of the cavity inner side plate 601 is rotatably connected to a transmission gear 605, and the driven gear 602 is meshed with the transmission gear 605. The purpose of this setting is that during the lamination process of the two groups of master materials, the transmission gear 605 drives the driven gear 602 to rotate inside the inner plate 601 of the cavity. Since the radius of the transmission gear 605 and the driven gear 602 are the same, the rotation speed of the two first pulleys 603 connected to their outer ends is kept consistent, so that the rotation speed of the master materials fixed on the outer ends of the two feeding air expansion shafts 3 is kept consistent. The two groups of master materials with the same rotation speed avoid the problem of folding, stacking and entanglement of the two groups of master materials during the lamination process due to the difference in the rotation speed of the two feeding air expansion shafts 3, thereby avoiding damage to the master materials.

[0040] The synchronous material retraction and unloading mechanism 6 also includes a cavity outer plate 606 fixedly connected to the outer end of the first side plate 2. A servo motor 607 is fixedly connected to the outer end of the cavity outer plate 606. The output end of the servo motor 607 is fixedly connected to the transmission gear 605. The purpose of this arrangement is that during the material retraction and unloading process, the servo motor 607 drives the transmission gear 605 to rotate the cover, thereby driving the driven gear 602 engaged at its outer end to rotate.

[0041] The synchronous retracting and unreeling mechanism 6 also includes a second pulley 608 rotatably connected to the interior of the cavity outer plate 606. There are four second pulleys 608, and a second connecting belt 609 is sleeved between two adjacent second pulleys 608. Two of the second pulleys 608 are fixedly connected to the coil air-inflating shaft 4, and one of the second pulleys 608 is fixedly connected to the output end of the servo motor 607. The purpose of this arrangement is that during operation, the output end of the servo motor 607 drives the fixed second pulleys 608 to rotate within the cavity outer plate 606. Because the four second pulleys 608 have the same radius, the rotation speeds of the loading air-inflating shaft 3 and the coil air-inflating shaft 4 are consistent, preventing the rotation speed difference between the loading air-inflating shaft 3 and the coil air-inflating shaft 4 from pulling on the coated double-sided tape and causing it to tear.

[0042] In this embodiment, two groups of masterbatch are respectively clamped to the outer ends of two groups of feeding air-inflating shafts 3, and one end of the two groups of masterbatch is passed between the two groups of squeezing rollers 15. According to the required cutting length of the double-sided tape at the reel and its outer end, the spacing of the multiple shearing frames 19 is adjusted. After the double-sided tape after lamination is cut by the cutter head 20 inside the shearing frame 19, one end of the cut double-sided tape is respectively connected to the two coil air-inflating shafts 4. During the lamination process, the transmission gear fixed at the output end of the servo motor 607 605 drives the first pulley 603 to which it is connected to rotate. The rotating first pulley 603 drives the first connecting belt 604 at its outer end to rotate, and the driven gear 602 rotates at the same time, causing the two feeding air-expansion shafts 3 to rotate in opposite directions. At this time, the masterbatch on the outer ends of the two feeding air-expansion shafts 3 rotates to be stripped and coated. At the same time, the second connecting belt 609 drives the second pulley 608 to rotate, thereby rotating the two winding air-expansion shafts 4. The two winding air-expansion shafts 4 carefully rewind the slit double-sided tape. The radius of the first pulley 603 and the second pulley 608 is the same, so that the rotation speed of the feeding air-expansion shaft 3 and the winding air-expansion shaft 4 is consistent. This prevents the speed difference between the feeding air-expansion shaft 3 and the winding air-expansion shaft 4, which may cause the two sets of masterbatch to fold during the coating process due to the speed difference. This improves the stability of the masterbatch coating process and avoids masterbatch waste.

[0043] Example 2:

[0044] See also Figure 1-7This embodiment provides a further improved technical solution based on the first embodiment:

[0045] A second side panel 7 is fixedly connected to the top of the chassis 1, away from the first side panel 2. A hinged plate is provided on the outside of the second side panel 7, which engages the loading air shaft 3 and the coiling air shaft 4. This arrangement allows the rotatable hinged plate to facilitate loading and unloading operations on the loading air shaft 3 and the coiling air shaft 4.

[0046] The outer end of the feeding air-inflating shaft 3 is sleeved with a positioning disk 8, which is located on the inner side of the first side plate 2. The positioning disk 8 is rotatably connected to a turntable 9 inside. A telescopic rod 11 is symmetrically fixedly connected to the inner side of the positioning disk 8. The outer end of the telescopic rod 11 is slidably connected to a sleeve rod 10, which is fixedly connected to the inner side of the first side plate 2. A first spring 12 is fixedly connected between the sleeve rod 10 and the telescopic rod 11. The purpose of this arrangement is that the elastic force generated by the first spring 12 causes the positioning disk 8 connected to the telescopic rod 11 to squeeze from one side of each of the two sets of masterbatch, thereby ensuring that the two ends of the two sets of masterbatch are aligned, avoiding the occurrence of a large amount of waste at the edge of the double-sided tape after lamination due to the two sets of masterbatch being misaligned.

[0047] A feed roller 13 is fixedly connected between the first side plate 2 and the second side plate 7. A connecting plate 14 is symmetrically fixedly connected to the inner sides of the first side plate 2 and the second side plate 7. An extrusion roller 15 is slidably connected to the interior of the connecting plate 14. The feed roller 13 is arranged between the feeding air-inflating shaft 3 and the extrusion roller 15. A second spring 16 is fixedly connected between the connecting plate 14 and the extrusion roller 15. The purpose of this arrangement is that the feed roller 13 is used to convey the masterbatch, and the elastic force generated by the second spring 16 increases the force of the two sets of extrusion rollers 15 on the two sets of masterbatch, thereby preventing bubbles from forming in the gap between the two sets of masterbatch during the lamination process, which affects the production quality of the double-sided tape.

[0048] A separating roller 17 is symmetrically connected between the first side plate 2 and the second side plate 7, and is arranged between the squeezing roller 15 and the coil air expansion shaft 4. The purpose of this arrangement is that the separating roller 17 is used to separate the double-sided tape after cutting.

[0049] A material distribution shaft 18 is fixedly connected between the first side plate 2 and the second side plate 7. The material distribution shaft 18 is arranged between the material distribution roller 17 and the coil air expansion shaft 4. The outer end of the material distribution shaft 18 is slidably connected to the shearing frame 19. A fixed knob is threadedly connected between the material distribution shaft 18 and the shearing frame 19. A cutter head 20 is fixedly connected to the inside of the shearing frame 19. A support shaft 21 is fixedly connected between the shearing frames 19. A turning groove 22 is provided at the outer end of the second side plate 7. One end of the support shaft 21 is slidably connected to the inside of the turning groove 22. The outer end of the support shaft 21 is threadedly connected to a fixing nut 23. The purpose of this arrangement is that when the double-sided tape after lamination is cut, the support shaft 21 inside the turning groove 22 can be rotated according to the width requirement of the double-sided tape to turn the shearing frame 19 and adjust the spacing between several shearing frames 19. During the cutting process, the cutter head 20 cuts the double-sided tape.

[0050] In this embodiment, after the two groups of master materials are sleeved on the outer ends of the feeding air-inflating shaft 3, the rotating turntable 9 inside the positioning disk 8 contacts from one end of the master material, so that one end of the two groups of master materials are located on the same horizontal plane. During the laminating process, the excess material at the edge of the double-sided tape is reduced, which saves costs. Before slitting the double-sided tape, the distance between the two adjacent groups of shearing frames 19 is adjusted according to the requirements of the roll and the slitting width of the double-sided tape, and the position of the shearing frame 19 on the top of the material-splitting shaft 18 is fixed using a fixing knob. During the winding process of the double-sided tape, the knife inside the shearing frame 19 The head 20 cuts the double-sided tape, and multiple sets of shearing frames 19 can cut the double-sided tape at the same time, which speeds up the efficiency of cutting the double-sided tape. The multiple sets of shearing frames 19 that are fixed in advance are measured to improve the accuracy of cutting the double-sided tape. When adjusting the spacing of the shearing frames 19, the support shaft 21 is rotated inside the flipping groove 22, so that the shearing frames 19 are flipped, which facilitates the adjustment operation. After adjusting the spacing of the multiple sets of shearing frames 19, the position of the support shaft 21 is fixed with the fixing nut 23 to prevent the shearing frames 19 from flipping due to resistance during the shearing process, which affects the cutting effect of the double-sided tape.
