Description

Technical Field

[0001] The utility model belongs to the technical field of packaging product production, and in particular relates to an automatic continuous laminating device for double-sided adhesive tape of a specified length. Background Art

[0002] It is often necessary to affix various double-sided tapes for aesthetic and logo purposes on the outer packaging of products. In production, double-sided tape is sometimes affixed manually to the surface of the product. For the need to affix rolls of double-sided tape to products, the manual method is obviously more troublesome, consumes high labor costs, and the quality is not very good, and may even be crooked. Of course, it is also possible to use double-sided tape affixing equipment, and the guide roller squeezes the product to be affixed and the double-sided tape together. However, when the product to be affixed is affixed with the double-sided tape, deviations are likely to occur, that is, the laminating length of the double-sided tape is not easy to control, and there may even be excess tape overflowing and remaining on the edge of the product to be affixed, resulting in an unsightly final product.

[0003] Therefore, it is necessary to improve the existing technology and provide more convenient equipment to complete the double-sided adhesive bonding of products with high quality. Utility Model Content

[0004] The purpose of the utility model is to provide an automatic continuous bonding device for double-sided tape of a specified length, which solves the problem of how to set the bonding length in the prior art. The bonding length can be set freely, which reduces the downtime of manual bonding, realizes automated intelligent manufacturing of the production line, and automates the data continuity of the entire process of double-sided tape bonding from the beginning to the end.

[0005] An automatic continuous laminating device for double-sided adhesive tape of a specified length comprises a movable lifting mechanism, an unwinding mechanism, a rewinding mechanism, and an electric control box. One end of the double-sided adhesive tape is wound and connected with the unwinding mechanism, and the other end thereof passes through a glue-breaking mechanism, an elastic pressure roller mechanism, and a support roller assembly in sequence, and is connected to the rewinding mechanism. The support roller assembly and the rewinding mechanism are connected to a power mechanism. The unwinding mechanism, the rewinding mechanism, the glue-breaking mechanism, the pressure roller sensing assembly, the unwinding sensing assembly, and the power mechanism are all connected to a single-chip microcomputer.

[0006] It also includes a constant linear speed structure for maintaining a uniform speed of the double-sided adhesive tape and a torsional self-slip structure for preventing the unwinding mechanism and the rewinding mechanism from rotating freely.

[0007] It should be noted that the mobile lifting mechanism is an existing technology, including a horizontal moving mechanism and a reciprocating lifting mechanism, so as to realize the movement and adjustment of the unwinding mechanism, the winding mechanism, the electrical control box and other mechanisms or components. In order to simplify the design, it is no longer marked in the drawings of this application. For example, the horizontal moving mechanism can be a screw transmission mechanism, and the reciprocating lifting mechanism can be a gear and rack mechanism.

[0008] The elastic pressure roller mechanism includes a sliding seat, a rubber roller rotatably connected to the sliding seat at both ends, a support seat movably connected to the sliding seat, a fixed plate vertically connected to the support seat, a fixed column passing through the fixed plate and the sliding seat, and a spring sleeved on the fixed column, wherein the spring is arranged between the fixed plate and the sliding seat, and the side of the double-sided tape passes through the bottom of the rubber roller.

[0009] The glue cutting mechanism includes a positioning plate, a baffle fixed below the positioning plate, and a telescopic cylinder fixed below the baffle, wherein the free end of the telescopic cylinder is fixedly connected to a vertically placed moving plate 1, the bottom surface of the moving plate 1 is fixedly connected to a horizontally placed moving plate 2, and the moving plate 1 is fixedly connected to a moving plate 3;

[0010] A cutter is horizontally fixed on the bottom surface of the movable plate three, the baffle is L-shaped and includes a horizontal part connected to the positioning plate and a vertical part placed vertically, the double-sided tape is vertically attached to the vertical part, and one end of the cutter is perpendicularly arranged to the double-sided tape and the vertical part.

[0011] The glue cutting mechanism also includes a cutting position control component; the cutting position control component includes a limit block fixed on the outside of the telescopic cylinder, a fine-tuning fixed block fixed on the movable plate 2, and a micrometer head fixed on the fine-tuning fixed block, and the micrometer head moves close to or away from the limit block.

[0012] The support roller assembly includes support pulley four, support pulley one, support pulley two, support pulley three, and a power roller, one end of which is rotatably connected to the electric control box, one end of the double-sided tape passes through the support pulley four, the support pulley one, the support pulley two, the support pulley three, and the power roller in sequence, and the power roller is connected to the power mechanism.

[0013] The unwinding mechanism is connected to an unwinding induction component; the unwinding induction component comprises a back plate fixed on the electric control box and two proximity switches connected to the back plate.

[0014] The elastic pressure roller mechanism is connected to a pressure roller sensing assembly; the pressure roller sensing assembly comprises a proximity switch 1 for detecting the position of the sliding seat, and the proximity switch 1 is arranged between the fixed plate and the sliding seat;

[0015] It also includes an optical fiber sensor arranged near the rubber roller.

[0016] The power mechanism comprises a driving motor and a chain connected to the driving motor. The chain also passes through the power roller and a winding shaft coaxially connected to the winding mechanism.

[0017] The constant linear speed structure includes PU glue coated on the power roller, and the double-sided tape bypasses the PU glue.

[0018] The torsion self-slip structure includes a rotating drum rotatably sleeved on the winding shaft or the unwinding shaft, and a plurality of spring glass beads vertically passing through the outer surface of the rotating drum, wherein the spring glass beads pass through the outer side of the rotating drum and contact and abut against the outer side of the winding shaft or the unwinding shaft;

[0019] The front and rear ends of the rotating drum are provided with drum holes, the winding shaft or the unwinding shaft is passed through the drum holes, and the unwinding shaft is connected to the unwinding mechanism.

[0020] The single-chip microcomputer program controls the double-sided tape machine from the start induction to the end induction signal output to realize automatic double-sided tape application. The linear speed of the power roller * time = length L, and the driving motor running time controls the length setting value. The constant linear speed structure solves the problem of inconsistent tension between the unwinding of the double-sided tape and the winding of the base paper at the same time. The power roller is used as a reference to determine the movement length value of the double-sided tape, ensuring the consistency of the length of the double-sided tape on the unwinding roller and the base paper on the winding roller, thereby achieving consistent tension;

[0021] When the unwinding and rewinding torque of the torsional self-slip structure is greater than the power roller, the unwinding and rewinding remain stationary, assisting in achieving constant linear speed operation and avoiding over-movement of the unwinding and rewinding rollers due to inertia, thereby ensuring the tension of the tape and making the double-sided tape sticking length stable and accurate.

[0022] Through the elastic pressure roller mechanism and the proximity switch output signal, when the rubber roller and the object to be adhered are at the set pre-pressure depth, the output signal is used to automatically stick the double-sided tape. While stably sticking the double-sided tape, the automation level of the production line is greatly improved.

[0023] At the unwinding position of the double-sided tape, the second proximity switch / reflective optical fiber / diffuse reflection optical fiber output signal is fixed to make the double-sided tape roll alarm when the set margin is reached, ensuring that the tape will not fall off or be missed, while giving the operator enough time to prepare materials and replace materials in time.

[0024] This solution adopts a combination of single-chip microcomputer + machinery + electric control box (the single-chip microcomputer is set in the electric control box), which greatly compresses the external dimensions of the equipment, so that it can better reduce the installation space requirements.

[0025] The positive effects of the utility model are as follows:

[0026] (1) The elastic pressure roller mechanism and the glue cutting mechanism solve the problem that the glue sticking length can only be fixed, so that the glue sticking length L can be freely set;

[0027] (2) Through the constant linear speed structure and torsional self-slip structure, the tension of the double-sided tape is kept consistent during winding and unwinding, ensuring the stability of the adhesive length and reducing the precision deviation;

[0028] (3) The roller sensing component reduces the precision deviation of the starting position of the mechanical roller labeling, and the starting glue has a signal output, which improves the automation relevance, improves the stability of the glue position, strengthens the consistency and stability of double-sided tape, and improves the automation level of the production line;

[0029] (4) This solution uses an unwinding sensor component to avoid the problem of double-sided tape falling off or missing due to the double-sided tape being completely used up. BRIEF DESCRIPTION OF THE DRAWINGS

The spring is arranged between the fixed plate 31 and the sliding seat 2, and the side of the double-sided tape 13 passes through the bottom of the rubber roller 1.

[0042] The glue cutting mechanism includes a positioning plate 15, a baffle 16 fixed below the positioning plate 15, and a telescopic cylinder 19 fixed below the baffle 16.

[0046] The unwinding mechanism is connected to the unwinding sensing component; the unwinding sensing component includes a back plate fixed on the electric control box 11 and a proximity switch 26 connected to the back plate. The unwinding sensing component includes a back plate fixed on the electric control box 11 and a proximity switch 26 connected to the back plate. The proximity switch 26 is used to sense whether the double-sided tape on the unwinding roller is used up. For example, the proximity switch 26 can detect whether there is a signal on the outside of the double-sided tape on the unwinding roller.

[0048] It also includes an optical fiber sensor 24 disposed near the rubber roller 1 , and the optical fiber sensor 24 is used to determine the position of the object being pasted.

[0049] Specifically, when the rubber roller 1 contacts the object to be glued, the sliding seat 2 slides along the supporting seat 3, the spring (the spring is not marked in the figure) is compressed, and the sliding seat 2 approaches the proximity switch 25. The specific position of the sliding seat 2 is adjusted by the proximity switch 25 to achieve the glue sticking process under a certain pressure.

[0050] The power mechanism includes a driving motor 10 and a chain connected to the driving motor 10. The chain also passes through a power roller 7 and a winding shaft coaxially connected to the winding mechanism.

[0051] The constant linear speed structure includes PU glue coated on the power roller, and the double-sided tape 13 passes around the PU glue.

[0052] The backing paper of the double-sided tape 13 is attached to the PU adhesive, and has a large friction force. Under the action of the friction force, the driving motor 10 can drive the power roller 7 to rotate.

[0053] The torsional self-slip structure includes a rotating drum 27 rotatably sleeved on the reel or unreel, and a plurality of spring glass beads 28 vertically passing through the outer surface of the rotating drum 27. The spring glass beads 28 pass through the outer side of the rotating drum 27 and contact and abut against the outer side of the reel or unreel;

[0054] The front and rear ends of the rotating drum 27 are provided with a cylinder hole 29, and a reel or an unreel shaft is passed through the cylinder hole 29, and the unreel shaft is connected to the unreeling mechanism. The spring glass bead 28 is a prior art and will not be described in detail here.

[0055] The reel shaft is coaxially connected to the reel roller 9 , and the unreel shaft is coaxially connected to the unreel roller 12 ; the reel roller 9 carries the base paper 8 after the adhesive layer is removed, and the unreel roller 12 carries the double-sided adhesive tape 13 .

[0056] In actual work, the rotating drum 27 rotates. When rotating, the spring glass bead 28 has a strong point contact force with the winding shaft or the unwinding shaft. Under this friction force, the free rotation of the winding shaft or the unwinding shaft is avoided, ensuring that the double-sided tape 13 has a certain tension as a whole.

[0057] It should be noted that the automatic continuous laminating device disclosed in this scheme is connected to the linear reciprocating moving mechanism through a movable lifting mechanism, and the movable lifting mechanism swings up and down to adjust the upper and lower heights of the glue, and the whole is controlled by a single-chip microcomputer.

[0058] The specific working process of this utility model:

[0059] The scheme consists of eight parts: a single chip microcomputer, an unwinding mechanism, an unwinding sensing component, a glue breaking mechanism, an elastic pressure roller mechanism, a pressure roller sensing component, a rewinding mechanism, and an electric control box 11.

[0060] The double-sided film is stuck in the unwinding mechanism, with the unwinding sensing component on the back (adjusting the sensing output signal at the predetermined margin position) passing through the glue-breaking mechanism (the glue is broken but the base paper is not broken), through the elastic pressure roller mechanism, through the support roller assembly and the constant linear speed structure, and finally completed by the winding mechanism. The winding mechanism winds up the base paper to keep the overall continuous and unbroken tape.

[0061] Specifically, the whole machine is controlled by a single chip microcomputer, and the rubber roller is pressed down onto the object to be pasted, and the position of the object to be pasted is sensed by the optical fiber sensor 24, pre-pressed by 0.5-1.0mm, and the proximity switch 25 senses the signal output, and the signal is input into the single chip microcomputer;

[0062] At this time, the single chip microcomputer controls the driving motor 10 to rotate and pull the power roller 7 on the constant linear speed structure. The rotation circumference of the power roller 7 is used as a reference for the length of the tape output to control the length of the tape output Lmm (customizable). At the same time, the reeling mechanism reels the base paper (the adhesive layer has been peeled off).

[0063] When the double-sided adhesive tape is pasted to L-68mm, a delay of 250ms is made, and the adhesive layer is cut off by the adhesive cutting mechanism, that is, the telescopic cylinder 19 pushes the moving plate 17, the moving plate 2171, and the moving plate 3 18 to move, and the moving plate 3 18 drives the cutter 23 to cut the adhesive layer on the double-sided adhesive tape 13, and the micrometer head 20 and the fine-tuning fixed block 21 move. The relative position of the micrometer head 20 and the limit block 22 is adjusted to determine the movement displacement of the cutter 23, thereby ensuring that the adhesive layer is cut off without damaging the base paper;

[0064] Then, the elastic pressure roller mechanism presses the 68mm long adhesive layer down to fit the object, and the remaining 68mm (68mm is the factory setting value of the equipment) is pasted; finally, the lifting mechanism is moved upward to reset.

[0065] Technical features not described in the present invention can be achieved through or by adopting existing technologies, and will not be elaborated here. Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
