[0002] Double-sided tape is a tape with sticky sides. This kind of tape is widely used in the bonding of leather, stationery, electronics, automobiles and handicrafts, with remarkable effects. Double-sided tape can not only be used as bonding tape, but also as protective tape. It has the advantages of good processing, easy tearing and no residual glue.

[0003] In the production process of double-sided adhesive tape, the upper and lower release films need to be laminated with the middle adhesive layer.

[0026] The adhesive tape 3, the upper release film 5 and the lower release film 4 are respectively fed into between the squeezing roller 8 and the fixed roller 7 in the frame 6, and the adhesive tape 3, the upper release film 5 and the lower release film 4 are attached together to form a double-sided adhesive tape by the pressure between the squeezing roller 8 and the fixed roller 7;

[0027] The defoaming mechanism 9 is respectively arranged on the outside of the squeezing roller 8 and the fixing roller 7, and the defoaming mechanism 9 includes a buffer sleeve 901, a pressure roller tooth 902 and a chamfered portion 904. The pressure roller tooth 902 is evenly distributed on the outside of the buffer sleeve 901. The pressure roller tooth 902 can be used to drive out the bubbles generated inside the adhesive tape 3, the upper release film 5 and the lower release film 4 when they are attached together;

[0028] The tips of the pressing roller teeth 902 are all provided with chamfered portions 904, so that the surface of the double-sided adhesive tape is not easily scratched when being squeezed;

[0029] The defoaming mechanism 9 further includes an elastic strip 903, and the elastic strip 903 is distributed inside the buffer sleeve 901 in a concentric circle structure;

[0030] The buffer sleeve 901 and the elastic strip 903 are both made of silicone material, which has a certain elastic buffering effect. A margin can be left in the process of squeezing the double-sided adhesive tape, which is not easy to cause rigid squeezing of the double-sided adhesive tape and prevent damage.

[0031] A reinforcing layer 11 is provided inside the squeezing roller 8 and the fixing roller 7, and support rods 10 are evenly distributed inside the reinforcing layer 11 to ensure the structural strength inside the squeezing roller 8 and the fixing roller 7, so that they are not easily bent or deformed;

[0032] A screw rod 15 is provided on one side of the frame 6, and a driving block 14 is sleeved on the screw rod 15, and the driving block 14 is connected to one end of the squeezing roller 8;

[0033] A housing 18 is provided at one end of the top of the frame 6, and a servo motor 19 is provided inside the housing 18. A driving gear 12 is provided at the output end of the servo motor 19 through a roller. The top of the screw rod 15 extends into the housing 18, and a driven gear 13 meshing with the driving gear 12 is provided at the top of the screw rod 15.

[0034] The servo motor 19 can drive the driving gear 12 to rotate, so that the driven gear 13 and the screw 15 rotate, and drive the driving block 14 to move up and down along the screw 15, thereby adjusting the distance between the squeezing roller 8 and the fixed roller 7. The thickness of the double-sided adhesive to be produced can be adjusted to meet different processing requirements;

[0035] A guide rod 23 is provided on one side of the frame 6 away from the screw rod 15, and one end of the squeezing roller 8 close to the guide rod 23 is slidably sleeved with the guide rod 23 through a guide sleeve, so as to guide and limit the squeezing roller 8 when it moves up and down;

[0036] Sleeves 16 are provided on both sides below the fixed roller 7 through brackets, and pressure-bearing parts 20 are provided inside the sleeves 16 through rigid springs 21, and brackets 17 are provided on the tops of the pressure-bearing parts 20, and the tops of the brackets 17 are connected to both ends of the fixed roller 7;

[0037] When the squeezing roller 8 presses down the double-sided adhesive tape, a force is generated on the fixed roller 7. The pressure on the fixed roller 7 causes the bracket 17 at the bottom to squeeze the pressure-receiving member 20, so that the pressure-receiving member 20 compresses the rigid spring 21 in the sleeve 16. The pressure is dispersed and buffered by the restoring effect of the rigid spring 21, thereby preventing the fixed roller 7 from being damaged due to excessive pressure.

[0038] Limit blocks 22 are provided at both ends of the bottom of the pressure piece 20, and limit grooves matching the limit blocks 22 are provided on both sides of the sleeve 16 to limit the range of motion of the rigid spring 21 to prevent it from shaking significantly.

[0039] The specific model and specifications of the servo motor 19 need to be determined by selection calculation based on the specification parameters of the device. The selection calculation method is existing technology, so it will not be described in detail.

[0040] Working principle: When the embodiment of the present application is in use, the sticky tape 3, the upper release film 5 and the lower release film 4 are respectively fed into the squeeze roller 8 and the fixed roller 7 in the frame 6, and the pressure between the squeeze roller 8 and the fixed roller 7 is used to stick the sticky tape 3, the upper release film 5 and the lower release film 4 together to form a double-sided adhesive tape. The outer sides of the squeeze roller 8 and the fixed roller 7 are provided with a defoaming mechanism 9, and the defoaming mechanism 9 includes a buffer sleeve 901, a pressure roller tooth 902, an elastic strip 903 and a chamfered portion 904. The buffer sleeve 901 is sleeved on the outside of the squeeze roller 8 and the fixed roller 7, and the pressure roller teeth 902 are evenly distributed on the outer side of the buffer sleeve 901. The pressure roller teeth 902 can be used to drive out the bubbles generated inside the sticky tape 3, the upper release film 5 and the lower release film 4 when they are stuck together. At the same time, the tips of the pressure roller teeth 902 are provided with chamfered portions 904, so that it is not easy to scratch the surface of the double-sided adhesive tape when squeezing it. The elastic strip 903, the buffer sleeve 901 and the elastic strip 903 are all made of silicone material, which has a certain elastic buffering effect. A margin can be left in the process of squeezing the double-sided adhesive, and it is not easy to cause rigid squeezing of the double-sided adhesive to prevent damage. In addition, the servo motor 19 can drive the active gear 12 to rotate, so that the driven gear 13 and the screw rod 15 rotate, and drive the drive block 14 to move up and down along the screw rod 15, thereby adjusting the distance between the squeezing roller 8 and the fixed roller 7. It can be adjusted according to the thickness of the double-sided adhesive to be produced to meet different processing requirements. At the same time, when the squeezing roller 8 presses down the double-sided adhesive, it will generate a force on the fixed roller 7. The pressure on the fixed roller 7 prompts the bottom bracket 17 to squeeze the pressure-bearing part 20, so that the pressure-bearing part 20 compresses the rigid spring 21 in the sleeve 16. The pressure is dispersed and buffered by the recovery effect of the rigid spring 21 to prevent the fixed roller 7 from being damaged by excessive pressure.
