Description

Technical Field

[0001] The present invention relates to a production equipment for tear tape web paper for the production of tear tape web paper. Background Art

[0002] Previously, web paper was mostly packaged with heat shrinkable film or outer wrapping paper. With social progress, especially in the European market, web paper began to be packaged without heat shrinkable film. Instead, the web paper is directly sealed with glue at the paper edge, and it is convenient to open the seal of the web paper. A tear tape is provided inside the seal of the web paper. The distance of the tear tape from the seal position is generally slightly greater than the circumference length of the web paper. When in use, after tearing off the tear tape, the seal of the web paper is naturally opened, and the web paper can be unfolded for use. To meet the market demand, it is urgent to develop a production equipment for tear tape web paper dedicated to the production of tear tape web paper. Summary of the Invention

[0003] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a production equipment for tear tape web paper for fully automated and efficient production of tear tape web paper and ensuring the accurate sealing position of the web paper.

[0004] The present invention is completed by adopting the following technical solutions:

[0005] The production equipment for tear tape web paper is characterized in that: it includes a paper feeding and conveying component, a paper edge unfolding and conveying component, and a paper edge rewinding and conveying component. The paper feeding and conveying component is used to convey the web paper and detect the paper edge of the web paper, so that the web paper roll with consistent paper edges is sent to the paper edge unfolding and conveying component. The paper edge unfolding and conveying component is used to unfold the paper edge of the web paper, paste a tear tape and apply sealing glue inside the paper edge after unfolding, and send it to the paper edge rewinding and conveying component. In the paper edge rewinding and conveying component, the unfolded paper edge is rewound to seal the web paper and send it out.

[0006] The paper feeding and conveying component includes a paper feeding conveyor belt driven by power. A sponge pressing strip is arranged above the paper feeding conveyor belt along the paper feeding direction. During operation, the height distance between the sponge pressing strip and the paper feeding conveyor belt matches the outer diameter of the web paper.

The positioning and receiving conveyor component is composed of a number of V-groove wheels arranged. The arrangement direction of the V-groove wheels is perpendicular to the output direction of the paper feeding conveyor belt, and an O-shaped conveyor belt is wound around the V-groove wheels.

[0008] The paper edge unfolding and conveying component includes an unfolding conveyor belt driven by power. The unfolding conveyor belt is provided with suction holes on the side for unfolding the paper edge. During operation, the suction holes are communicated with negative pressure. At the feeding end of the unfolding conveyor belt, there are a paper pushing block for unfolding the paper edge of the reel paper and a detection element for detecting the position of the paper edge. At the discharging end of the unfolding conveyor belt, there are a glue spraying head and an easy-tear tape pasting head. The glue spraying head is aligned with the paper edge sealing position, and the easy-tear tape pasting head is aligned with the position for pasting the easy-tear tape on the paper edge. The glue spraying head is installed on a transverse sliding frame, and the transverse sliding frame is controlled by a transverse sliding motor to drive for transverse adjustment. The transverse sliding motor is electrically connected to the detection element.

[0009] The easy-tear tape pasting head is installed on the transverse sliding frame.

[0010] The detection element is a wire-pulling displacement sensor.

[0021] The present invention will be described in detail below through specific embodiments:

[0022] As shown in the figure, the easy-tear tape roll paper production equipment of the present invention includes a paper feeding and conveying component 1, a paper edge unfolding and conveying component 3, and a paper edge rewinding and conveying component 4. The paper feeding and conveying component 1 is used to convey the roll paper A and detect the paper edge of the roll paper, so that the roll paper tube A with consistent paper edges is sent into the paper edge unfolding and conveying component 3. The paper edge unfolding and conveying component 3 is used to unfold the paper edge of the roll paper, stick an easy-tear tape on the inner side of the paper edge after unfolding, and apply a sealing glue, and then send it to the paper edge rewinding and conveying component 4. In the paper edge rewinding and conveying component 4, the unfolded paper edge is rewound to seal the roll paper A and then sent out.

[0023] The paper feeding and conveying component 1 includes a paper feeding conveyor belt 11 driven by a servo motor. Above the paper feeding conveyor belt 11, there is a sponge pressing strip 16 arranged along the paper feeding direction. During operation, the height distance between the sponge pressing strip 16 and the paper feeding conveyor belt 11 is slightly smaller than the outer diameter of the roll paper A. In this way, when the paper feeding conveyor belt 11 is driven by the motor, the roll paper A can be rolled and conveyed on the paper feeding conveyor belt 11. Above the paper feeding conveyor belt 11, there is also a material blocking plate 15. The material blocking plate 15 is pushed by a material blocking cylinder 14 to swing, so as to release or block the roll paper A rolling and conveying on the paper feeding conveyor belt 11. At a position close to the output end of the paper feeding conveyor belt 11, there is a paper edge detection photoelectric sensor 13 for detecting the paper edge of the roll paper A, and above this position, there is a paper edge detection wheel 12. The paper edge detection wheel 12 is closer to the paper feeding conveyor belt 11 than the sponge pressing strip 16. The paper edge detection wheel 12 is controlled and driven by a paper edge detection motor, and the paper edge detection motor is electrically connected to the paper edge detection photoelectric sensor 13. During operation, when the paper edge detection photoelectric sensor 13 detects the paper edge position of the passing roll paper A, it controls the paper edge detection wheel 12 to roll accordingly, and the friction drives the roll paper to rotate, so that the paper edge position of the roll paper A is basically kept consistent before being sent out. The output end of the paper feeding conveyor belt 11 is connected with a positioning and receiving conveyor component 2. The positioning and receiving conveyor component 2 is composed of a plurality of V-shaped grooved wheels 21 arranged in a row. The rolling arrangement direction of the V-shaped grooved wheels 21 is perpendicular to the output direction of the paper feeding conveyor belt 11. An O-shaped conveyor belt is wound around the V-shaped grooved wheels 21. In this way, the roll paper A with basically consistent paper edges output from the paper feeding conveyor belt 11 is still basically kept consistent when it reaches the unfolding conveyor belt 31 through the conveying of the positioning and receiving conveyor component 2.

[0024] The paper edge unfolding and conveying component 3 includes an unfolding conveyor belt 31 driven by a servo motor. The unfolding conveyor belt 31 is provided with suction holes 32 on the side for unfolding the paper edge. During operation, the suction holes 32 are communicated with negative pressure to adsorb and fix the outer side of the paper edge of the web A. At the feeding end of the unfolding conveyor belt 31, there are a paper pushing block 33 for unfolding the paper edge of the web A and a detection element for detecting the position of the paper edge. The paper pushing block 33 is actuated by a paper pushing cylinder 34. The detection element is a wire displacement sensor 35. The wire displacement sensor 35 is installed on the paper pushing cylinder 34, and the wire of the wire displacement sensor 35 is connected to the paper pushing block 33. Above the unfolding conveyor belt 31, an inclined baffle 36 is provided corresponding to the pushing end point of the paper pushing block 33. The inclined baffle 36 is provided with a rolling working surface (the rolling working surface is composed of arranged rollers); at the discharging end of the unfolding conveyor belt 31, there are a glue spraying machine and an easy tear tape pasting machine. The glue spraying machine has a glue spraying head 38, and the easy tear tape pasting machine has an easy tear tape pasting head 37. If the easy tear tape sent out by the easy tear tape pasting machine has no adhesiveness itself, another set of glue spraying machines needs to be set up. The glue spraying head 30 of the other set of glue spraying machines is aligned with the pasting position of the easy tear tape to spray glue on the pasting position of the easy tear tape in advance (see Figure 4 ), the glue spraying head 38 is aligned with the paper edge sealing position, and the easy tear tape pasting head 37 is aligned with the paper edge for pasting the easy tear tape. The glue spraying head 38 and the easy tear tape pasting head 37 are installed on a transverse sliding frame 39. The transverse sliding frame 39 is controlled by a transverse sliding motor 29 to drive and make a transverse adjustment. The transverse sliding motor 29 is electrically connected to the wire displacement sensor 35. During operation, after the paper edge of the web is adsorbed and fixed by the suction holes, when the paper pushing block pushes the web to unfold the paper edge, the wire displacement sensor will accurately sense the position of the paper edge. Then the paper edge information will be transmitted to the transverse sliding motor, so that the transverse sliding frame makes a transverse adjustment, making the glue spraying head accurately aligned with the position inside the paper edge that needs to be sealed, and spraying glue to ensure that the web can achieve accurate sealing position after the paper edge is rewound.

[0025] The paper edge rewinding and conveying component 4 includes a flat belt conveying table 40 and a roller conveying table 41 arranged front and back. The flat belt conveying table 40 is connected to the unfolding conveyor belt 31. Above the roller conveying table 41, there is a rewinding sponge conveyor belt 43, which is controlled and driven by a rewinding motor. In the middle of the roller conveying table 41, there is a rewinding lifting plate 42, which is pushed up and down by a lifting cylinder. In the normal state, the rewinding lifting plate 42 is lower than the roller conveying table 41. In the state of paper edge rewinding, the rewinding lifting plate 42 is pushed upward to be higher than the roller conveying table 41, so that the upper part of the reel paper A is in pressing contact with the rewinding sponge conveyor belt 43. Then, the rewinding motor controls and drives the rewinding sponge conveyor belt 43 to act, so that the reel paper A rolls towards the unfolded paper edge side, and the paper edge is rewound. Since the inner side of the paper edge has been coated with sealing glue, the reel paper A is accurately sealed. On the side of the roller conveying table 41, there is a paper output conveying component 5, which includes a fixedly installed paper output guiding track 52. The paper output guiding track 52 is inclined. Above the paper output guiding track 52, there is a paper output sponge conveyor belt 51, which is controlled and driven by a paper output motor. The height distance between the paper output sponge conveyor belt 51 and the paper output guiding track 52 is slightly smaller than the outer diameter of the reel paper A. The purpose is to re-compact the paper edge sealing position of the reel paper when the reel paper is sent out through the paper output conveying component, ensuring reliable sealing. At the outlet of the paper output guiding track 52, there is a chain conveyor roller platform 6, which means that a plurality of conveyor rollers are equidistantly installed on the conveyor chain, and the reel paper A is conveyed by the conveyor rollers. The chain conveyor roller platform 6 passes under the paper edge rewinding and conveying component 4, and a labeling machine 7 is arranged on the chain conveyor roller platform 6 for pasting labels on the surface of the finally sent-out reel paper.

[0026] The production of the tear tape roll paper of the present invention is carried out as follows: The roll paper A is fed in by the paper feeding conveyor belt 11, and the baffle plate 15 acts to release the roll paper in sequence. When the paper edge detection photoelectric sensor 13 detects the paper edge position of the passing roll paper, it controls the paper edge detection wheel 12 to roll correspondingly, driving the roll paper A to rotate so that the paper edge positions of the roll paper are basically the same. Subsequently, the roll paper A falls onto the V-groove wheel 21 for positioning. Under the conveying action of the O-shaped conveyor belt, the roll paper A is sent to the unfolding conveyor belt 31. At this time, the paper edge positions of the roll paper are still basically the same without large errors. Then, on the unfolding conveyor belt 31, the suction holes 32 are communicated with negative pressure to adsorb and fix the outer side of the paper edge of the roll paper A. After the adsorption and fixation, the paper pushing block 33 will push the roll paper A to move horizontally until the roll paper is squeezed and contacts the rolling working surface of the inclined baffle 36. Then the paper edge unfolds, and due to the friction effect, the roll paper will not temporarily roll back. During this process, the wire displacement sensor 35 will sense the accurate position of the paper edge and transmit the accurate paper edge position information to the horizontal sliding motor 29, so that the glue spraying head 38 is accurately adjusted to the position for gluing at the paper edge seal. Next, the roll paper with the unfolded paper edge is sent to the lower part of the glue spraying head 38 and the tear tape pasting head 37. The glue spraying head 38 sprays glue at the paper edge seal position, and the tear tape pasting head 37 pastes the tear tape at the paper edge pasting position. After the above actions are completed, the roll paper A is sent to the roller conveying table 41. When the probe detects that the roll paper is in place, the rewinding lifting plate 42 is lifted higher than the roller conveying table 41 and pushes the upper part of the roll paper A to tightly contact the rewinding sponge conveyor belt 43. Then the rewinding motor controls and drives the rewinding sponge conveyor belt 43 to act, so that the roll paper rolls towards the side of the unfolded paper edge, causing the paper edge to be rewound. Since the inner side of the paper edge has been coated with sealing glue, the roll paper A realizes accurate sealing. Then, the sealed roll paper A falls onto the chain conveyor roller platform 6 through the paper outlet guiding track 52. On the chain conveyor roller platform 6, the labeling machine 7 pastes a label on the surface of the roll paper A. Finally, the roll paper A is sent to the collection table 8 for collection. The above entire production process realizes the automatic production of the tear tape roll paper throughout the process, ensures the accuracy of the sealing position of the roll paper, the product appearance is neat and uniform, and the quality is guaranteed.
