Description

TECHNICAL FIELD

[0001] The present application belongs to the field of automation equipment, and particularly relates to an equipment and method capable of automatically cutting a fixed length of adhesive tape. BACKGROUND

[0002] The adhesive tape used in daily life usually exists in the form of an adhesive tape roll, and in the use link, the adhesive tape needs to be unwound from the adhesive tape roll by a certain length before being used. For example, the simplest way is to manually tear the adhesive tape from the adhesive tape roll, measure the required length, and then cut and use it with a blade or scissors. In the field of industrial production, this primitive way is laborious and low in efficiency, and thus an equipment is needed to automatically and quickly cut the required length of adhesive tape from the adhesive tape roll for use, and the user only needs to pick up the adhesive tape. There are similar equipments on the market, which can basically meet the above-mentioned functions, but mainly have the following problems: 1. The adhesive tape adaptability is not good enough, and only the PVC adhesive tape with soft and narrow material can be processed, and other adhesive tapes such as felt cloth and acetic acid cloth cannot be processed; 2. The equipment reliability is not good, and the service life is low. In the industrial production link with high frequency of use, the equipment can only be used for several weeks to several months before being scrapped; 3. The equipment stability is not good, which is manifested in the problems of frequent adhesive tape jamming, adhesive tape cutting failure, poor adhesive tape posture, and difficult processing of adhesive tape jamming, and the more the above-mentioned poor adaptability of the adhesive tape, the worse the stability; this leads the user to return to the above-mentioned most primitive way and resist the use of similar equipment which is unreliable and unstable. Therefore, the present application designs an equipment capable of automatically and quickly cutting a fixed length of adhesive tape, which has the advantages of wide adhesive tape adaptability, reliable and stable equipment, and easy operation.

[0057] The present application will be further described and illustrated in conjunction with the drawings and specific embodiments. The technical features of each embodiment in the present application can be combined accordingly without conflict.

[0058] As shown in Figure 1 and Figure 10 , the present application provides an automatic tape cutting machine, which mainly comprises an integrated tape unwinding part, a tape posture correction part, a tape cutting part, a tape pressing part, a door sealing part, an oiling part and a key control part.

[0059] The structure and connection mode of each part will be described in detail below.

[0060] In the present application, as shown in Figure 1 and 3As shown, the tape unwinding section mainly includes a tape fixing wheel 1, a tape conveyor wheel a6, and a tape conveyor wheel b7. The tape fixing wheel 1 is used to coaxially fix the tape roll 2 from the center and allows the tape roll 2 to rotate together along the central axis. The tape conveyor wheels a6 and b7 are used to unwind the tape from the tape roll 2. They can rotate in the same direction along their respective central axes, and their central axes are parallel. The tape conveyor wheel b7 is located below the tape conveyor wheel a6. Specifically, the rotation of the tape conveyor wheel a6 unwinds the tape from the tape roll 2, while the tape conveyor wheel b7, rotating at a faster speed than the tape conveyor wheel a6, peels the tape off the tape from the tape conveyor wheel a6 and conveys it downwards in the direction of rotation of the tape conveyor wheel b7.

[0061] In actual use, belt conveyor wheel b7 is located below belt conveyor wheel a6. Belt conveyor wheel a6 has several first discs evenly arranged axially, and belt conveyor wheel b7 has several second discs evenly arranged axially. Two first discs are positioned between adjacent second discs, meaning belt conveyor wheels a6 and b7 are formed as sheet-type conveyor wheels with one disc spaced evenly. When the belt is pressed onto belt conveyor wheel a6, belt conveyor wheel a6 rotates, unwinding the belt from belt roll 2 and conveying it towards belt conveyor wheel b7. When the belt is conveyed by belt conveyor wheel a6 to the intersection point with belt conveyor wheel b7, belt conveyor wheel b7 will peel the belt off from belt conveyor wheel a6 at a faster rotational speed than belt conveyor wheel a6 and convey it downwards in the rotation direction of belt conveyor wheel b7. This is because the two conveyor rollers need to have a speed difference (the conveyor roller a6 must rotate faster than the conveyor roller b7) to separate the conveyor belt from the previous roller. If there is no speed difference, the two conveyor rollers will rotate at the same speed, and the conveyor belt will be conveyed along the outer tangent circles of conveyor rollers a6 and b7. When the conveyor belt is conveyed along the outer tangent circle of conveyor roller b7, it will eventually get stuck inside the machine, thus failing to convey the conveyor belt effectively. At the same time, to reduce the contact area between conveyor rollers a6 and b7 and the conveyor belt (reduce friction), the surfaces of conveyor rollers a6 and b7 are made as follows... Figure 3 (b) shows the tooth shape (i.e., arc-shaped wave). The rotation speed of the conveyor wheel can be adjusted on the touch screen 38 to adapt to the dispensing speed of tapes of different sizes and viscosities.

[0062] In this invention, such as Figure 1 and 5 As shown, the tape pressing part includes a tape pressing assembly 4. The tape pressing assembly 4 is disposed above the tape conveyor wheel a6 and is used to press against the tape passing through the tape conveyor wheel a6.

[0063] As a preferred embodiment of the present invention, such as Figure 5As shown, the adhesive tape pressing assembly 4 mainly includes an adhesive tape guide roller 22, an adhesive tape pressing link 23 and an adhesive tape pressing cylinder 24. The adhesive tape guide roller 22 is located above the adhesive tape conveying wheel a6. The adhesive tape pressing link 23 is hingedly fixed to the housing of the automatic adhesive tape cutting machine as a fulcrum, and functions as a link arm. One end of the adhesive tape pressing link 23 is connected to the end of the adhesive tape guide roller 22, and the other end is connected to the output shaft of the adhesive tape pressing cylinder 24. The extension and retraction of the output shaft of the adhesive tape pressing cylinder 24 can control the contact pressure between the adhesive tape guide roller 22 and the adhesive tape conveying wheel a6.

[0064] In actual use, when the adhesive tape pressing cylinder 24 extends outward, the adhesive tape guide roller 22 is pressed toward the adhesive tape conveying wheel a6 through the link arm effect of the adhesive tape pressing link 23. When the adhesive tape pressing cylinder 24 retracts, the adhesive tape guide roller 22 is lifted upward and away from the adhesive tape conveying wheel a6 through the link arm effect of the adhesive tape pressing link 23. The main function is to prevent the adhesive tape from slipping on the conveying wheel a6, which can cause the adhesive tape to be cut off or not cut to the set length, resulting in failure to cut the adhesive tape. The switch for opening and pressing the adhesive tape guide roller 22 can be set on the touch screen 38.

[0065] In the present application, as shown in Figure 1 and 4 The adhesive tape cutting part mainly includes a scissors assembly 8 located below the adhesive tape conveying wheel b7, which is used to cut the uncoiled adhesive tape 10 to a fixed length.

[0066] As a preferred embodiment of the present application, as shown in Figure 4 The scissors assembly 8 mainly includes a scissors static blade 19, a scissors dynamic blade 20 and a scissors cylinder 21, and the main function is to cut the uncoiled adhesive tape 10 to a fixed length. Specifically, the fixed ends of the scissors static blade 19 and the scissors dynamic blade 20 are hingedly connected, and the cutting ends are located below the adhesive tape conveying wheel b7. The scissors dynamic blade 20 is connected to the output shaft of the scissors cylinder 21, and the rotation of the scissors dynamic blade 20 around the scissors static blade 19 is controlled by the extension and retraction of the output shaft of the scissors cylinder 21. That is, when the scissors cylinder 21 extends, it will drive the scissors dynamic blade 20 away from the scissors static blade 19. When the scissors cylinder 21 retracts, it will drive the scissors dynamic blade 20 to overlap the scissors static blade 19 to generate a shearing force to cut the uncoiled adhesive tape 10 to a fixed length.

[0067] In the present application, as shown in Figure 1 and 9 The oiling part mainly includes an oil absorbing filler 37, a manual oil injection port 36 and an automatic oil injection port 16. The oil absorbing filler 37 is located above the scissors assembly 8, and the top is provided with a manual oil injection port 36 and an automatic oil injection port 16 for lubricating the surface of the scissors after absorbing oil.

[0068] As a preferred embodiment of the present application, the oiling site mainly functions to lubricate the scissors. After long-time shearing or shearing of relatively sticky adhesive tapes, the static blade 19 and the dynamic blade 20 of the scissors will be covered with adhesive, which will cause the adhesive tape to be easily stuck to the scissors, affecting the smoothness of the adhesive tape. The oiling site is generally divided into automatic oiling and manual oiling. The automatic oiling is mainly realized by the automatic oiling cylinder 27, which is set to automatically pour oil from the oil canister to the oil-absorbing filler 37 after a certain number of shearing times of the scissors are set through the touch screen 38. The oil-absorbing filler 37 absorbs the oil poured by the automatic oiling cylinder 27 and then lubricates the surface of the scissors. The manual oiling is realized by directly pouring oil into the manual oiling port 36, and the oil-absorbing filler 37 is located below the manual oiling port 36. Both of them have the same effect. The automatic oiling will be described in detail below.

[0069] As shown in Figure 6 The automatic oiling port 16 is connected with an automatic oiling mechanism. The automatic oiling mechanism includes an automatic oiling cylinder 27, a reset spring 28, an oiling cylinder air inlet 29, an oiling cylinder inlet and outlet port 30, a three-way valve 31, a one-way valve a 32 and a one-way valve b 33. One end of the reset spring 28 is mounted on the automatic adhesive tape cutting machine shell, and the other end is fixed with the automatic oiling cylinder 27. The top of the automatic oiling cylinder 27 is respectively communicated with the oiling cylinder air inlet 29 and the oiling cylinder inlet and outlet port 30. The oiling cylinder inlet and outlet port 30 is connected with the one-way valve a 32 which can only enter oil and the one-way valve b 33 which can only exit oil through the three-way valve 31, and the one-way valve b 33 is communicated with the automatic oiling port 16 through a pipeline. The reset spring 28 can drive the automatic oiling cylinder 27 to extend and retract, change the air pressure in the automatic oiling cylinder 27 through the oiling cylinder air inlet 29, and then enter oil through the one-way valve a 32 or exit oil through the one-way valve b 33.

[0070] In actual use, the automatic oiling process is that the automatic oiling cylinder 27 is pushed out by the reset spring 28, causing the automatic oiling cylinder 27 to extend outward. When the automatic oiling cylinder 27 extends outward, an suction force is generated at the oiling cylinder inlet and outlet port 30 to the cylinder body of the automatic oiling cylinder 27, which can extract oil from the oil canister and flow to the one-way valve a 32 through the pipeline (note: the one-way valve a 32 is communicated from right to left and blocked from left to right. As shown in Figure 7When the oil flows through the three-way valve 31, because of the suction force generated at the oil injection cylinder inlet and outlet 30, the oil will flow into the automatic oil injection cylinder 27, so the oil will not flow to the one-way valve b33 direction. Therefore, when the automatic oil injection cylinder 27 extends forward, the oil is pumped from the oil canister into the cylinder body for storage. When the oil injection cylinder inlet 29 is flushed with gas, the automatic oil injection cylinder 27 will retract back. The oil stored in the cylinder body is pushed out, and the oil pushed out will pass through the oil injection cylinder inlet and outlet 30 and enter the three-way valve 31. Because the one-way valve a32 is open from right to left (as shown by the arrow direction), the oil pushed out cannot pass through the one-way valve a32 and can only flow in the direction of the one-way valve b33 (note: the one-way valve b33 is open from top to bottom and closed from bottom to top. As shown by the arrow direction), and then flows out of the one-way valve b33, is guided by the pipeline to flow into the automatic oil injection port 16, and finally the oil flows into the oil absorption filler 37. After each cut of the adhesive tape, the cutting blade 20 will stop below the oil absorption filler 37 and will be in close contact with the oil absorption filler 37. Therefore, after the oil absorption filler 37 absorbs enough oil, it can lubricate the cutting blade 20 below it. Figure 7 Figure 7

[0071] Manual oil injection is directly pouring oil into the manual oil injection port 36, and the oil absorption filler 37 is below the manual oil injection port 36, which has the same effect as automatic oil injection, and can be selected according to needs.

[0072] In the present application, as shown in Figure 1 , Figure 6 and Figure 8 , the door sealing part includes the door sealing mechanism 14 below the scissors assembly 8 and the adhesive tape pressing fixed seat 9, and the door sealing mechanism 14 and the adhesive tape pressing fixed seat 9 are respectively located on both sides of the unwound fixed-length adhesive tape 10. The horizontal movement of the door sealing mechanism 14 can realize clamping of the unwound fixed-length adhesive tape 10 with the adhesive tape pressing fixed seat 9.

[0073] As a preferred embodiment of the present application, the door sealing mechanism 14 mainly includes the adhesive tape pressing shaft 11, the door sealing cylinder 34 and the door sealing to position sensing switch 35. The door sealing mechanism 14 mainly plays the following roles: 1) the unwound fixed-length adhesive tape 10 is pressed by the adhesive tape pressing shaft 11 on the door sealing mechanism to the adhesive tape pressing fixed seat 9, which plays a role of fixing the adhesive tape. In this way, when the cutting blade 20 cuts the adhesive tape, the adhesive tape will not run around during cutting; 2) it also plays a sensing role. When the cut adhesive tape is taken by hand (at this time, the adhesive tape sticking surface is stuck on the adhesive tape pressing shaft), the cutting machine of the present application can enter the next cycle of unwinding and cutting the adhesive tape and a series of actions through the action of the sensing device.

[0074] In actual use, as shown in Figure 8 ​​As shown, the sensing device can include a trigger sensing sheet 25 and a trigger switch 26, which are arranged as follows: the adhesive tape pressing shaft 11 is arranged in parallel with the shafts of the adhesive tape conveying wheels a6 and b7, one end of the adhesive tape pressing shaft 11 is provided with the trigger sensing sheet 25, and the two ends are connected with the output shaft of the door closing cylinder 34 through horizontal moving frames, so that the adhesive tape pressing shaft 11 can be driven to move vertically along the shaft to realize clamping of the uncoiled fixed-length adhesive tape 10 by the adhesive tape pressing fixed seat 9. The adhesive tape pressing shaft 11 and the trigger sensing sheet 25 can rotate together along the shaft of the horizontal moving frame. The door closing cylinder 34 is provided with a door closing in-place sensing switch 35, and the adhesive tape pressing fixed seat 9 is provided with the trigger switch 26. In this way, when the cut adhesive tape is taken by hand (at this time, the adhesive surface of the adhesive tape is adhered to the adhesive tape pressing shaft), the adhesive tape pressing shaft 11 is rotated, and the trigger sensing sheet 25 is also rotated. When the uncoiled fixed-length adhesive tape 10 is pressed by the adhesive tape pressing shaft 11 of the door closing mechanism to the adhesive tape pressing fixed seat 9, at this time, the position of the trigger sensing sheet 25 is just in the trigger switch 26. When the trigger sensing sheet 25 rotates, the trigger switch 26 will generate a pulse (such as Figure 6 ), so as to enter the next cycle of uncoiling and cutting the adhesive tape and a series of actions.

[0075] Of course, in addition to the above-mentioned mechanical sensing mode, other sensing modes such as optical fiber sensing mode, proximity sensing, force sensing and the like can also be adopted, which can also achieve the same effect, that is, when the cut adhesive tape is taken by hand, the cutting machine enters the next cycle of uncoiling and cutting the adhesive tape and a series of actions, which will not be described here.

[0076] In the present application, as shown in Figure 1 and Figure 2 , the adhesive tape posture correction part includes an adhesive tape guide plate 5, an oil injection and air blowing integrated fixed seat 12, an inner side adhesive tape posture adjusting air inlet 15 and an outlet adhesive tape posture adjusting nozzle 13. The adhesive tape guide plate 5 is vertically arranged on the outer side of the adhesive tape conveying wheels a6 and b7, and is used for guiding the adhesive tape to move downward. The oil injection and air blowing integrated fixed seat 12 is provided with an air outlet on the lower side, which is used for blowing air to the adhesive tape to make the adhesive tape adhere to the adhesive tape guide plate 5. The air outlet is communicated with the inner side adhesive tape posture adjusting air inlet 15 connected with the air inlet device through an air path. The outlet adhesive tape posture adjusting nozzle 13 is located below the door closing mechanism 14, and is used for blowing the uncoiled fixed-length adhesive tape 10 outward.

[0077] In practical use, the inner belt posture adjustment is controlled by the inner belt posture adjustment air volume switch 38, which controls the air volume of the inner belt posture adjustment air inlet 15. When the inner belt posture adjustment air volume switch 38 is increased, the air volume entering the inner belt posture adjustment air inlet 15 increases, resulting in a larger volume of air blown out from the oil injection and air blowing integrated fixing seat 12. This increased air volume causes the belt head, as it detaches from the belt conveyor wheel b, to be pushed towards the belt guide plate 5 by the air blown out from the oil injection and air blowing integrated fixing seat 12. As the belt conveyor wheels a6 and b7 rotate continuously, the belt is continuously peeled off from the belt roll 2 and conveyed downwards along the belt guide plate 5. The inner belt posture adjustment is primarily to prevent the peeled belt head from being carried away by the rotation direction of the belt conveyor wheel b7 (especially for thin, narrow, and soft PVC belts). The unwound tape is controlled by blowing air to guide it downwards along the guide plate. The tape posture adjustment at the outlet is primarily to prevent static electricity generated during the unwinding process from causing the PVC tape to adhere to the sealing gate, making it difficult to retrieve. Therefore, air is used to blow the unwound tape 10 outwards for easier handling.

[0078] In this invention, such as Figure 10 As shown, the button control area is located on the housing of the automatic tape cutter, including a touch screen 38, a tape ejection button 39, an inner tape posture adjustment airflow switch 40, and an outlet tape posture adjustment airflow switch 41. The inner tape posture adjustment airflow switch 40 and the outlet tape posture adjustment airflow switch 41 are used to regulate the airflow from the air outlet and the outlet tape posture adjustment nozzle 13, respectively.

[0079] The present invention also provides a method for using the above-mentioned automatic tape cutter, as follows:

[0080] S1. Secure the tape roll 2 to the tape holding roller 1 with the non-stick side 3 facing upwards. On the touchscreen 38, click the pressing switch to move the pressing guide roller 22 of the pressing tape assembly 4 upwards, away from the tape conveyor roller a6. At this time, the pressing guide roller 22 will open upwards to facilitate tape feeding. Then, secure the new tape roll 2 to the tape holding roller 1 (Note: When placing the tape roll 2 onto the tape holding roller 1, the non-stick side 3 of the tape must face upwards). Pull the tape end and place it between the pressing guide roller 22 and the tape conveyor roller a6. On the touchscreen 38, click the pressing switch to move the pressing guide roller 22 downwards and press the tape end onto the tape conveyor roller a6.

[0081] S2. Then, click the tape eject button 39. Tape conveyor rollers a6 and b7 rotate simultaneously in the same direction, with belt conveyor roller b7 rotating faster than belt conveyor roller a6. The tape pressed between the tape guide roller 22 and belt conveyor roller a6 is conveyed downwards by the rotation of belt conveyor rollers a6 and b7. At the same time, the sealing mechanism 14 moves horizontally away from the tape pressing fixing seat 9 to open. The air outlet of the oil injection and air blowing fixing seat 12 blows air diagonally downwards to make the tape adhere to the tape guide plate 5 for transport (when the sealing door is closed, the oil injection and air blowing fixing seat 12 will not blow air), preventing the peeled tape head from being carried away along the rotation direction of belt conveyor roller b7. At the same time, the outlet tape attitude adjustment nozzle 13 blows the unwound tape 10 outwards to prevent the static electricity generated during the unwinding process from adhering to the sealing mechanism 14 and making it difficult to pick up.

[0082] S3. When the conveyor belt reaches the set length, both conveyor belt rollers a6 and b7 stop rotating simultaneously. After stopping, the sealing cylinder 34 of the sealing mechanism 14 extends forward, driving the conveyor belt pressing shaft 11 to press the unwound fixed-length conveyor belt 10 onto the conveyor belt pressing fixing seat 9, thus closing the sealing mechanism 14 and fixing the unwound fixed-length conveyor belt 10. When the sealing cylinder 34 extends forward to its final position, closing the sealing mechanism 14, the sealing position induction switch 35 senses the signal, causing the scissor cylinder 21 of the scissor assembly 8 to retract and drive the scissor moving blade 20 to rotate. When the scissor moving blade 20 rotates below the scissor stationary blade 19, a shearing force is generated, cutting the conveyor belt pressed between the conveyor belt pressing shaft 12 and the conveyor belt pressing fixing seat 9. Simultaneously, the scissor cylinder 21 retracts to its position sensing point 42, which senses the signal. The scissor cylinder 21 immediately extends, causing the moving blade 20 of the scissors to rotate away from the stationary blade 19, completing the cutting operation. After the scissor cylinder 21 extends, the scissor cylinder extension sensing point 43 senses the signal, and the sealing cylinder 34 releases its extension pressure. At this time, the tape pressing shaft 11 loses the pressure that holds the tape down, and the force required to pick up the tape becomes very small (it's just the adhesive force of the tape sticking to the tape pressing shaft 11).

[0083] S4. When the door sealing mechanism 14 is closed, the tape pressing shaft 11 presses against the tape pressing fixing seat 9. At this time, the sensing device will generate a pulse signal and repeat steps S2 to S4.

[0084] In this embodiment, when the sensing device uses a trigger sensing element 25 and a trigger switch 26, the specific steps are as follows:

[0085] When the door closing mechanism 14 is closed, the tape pressing shaft 11 presses against the tape pressing fixed seat 9, and the position of the trigger induction sheet 25 is just within the induction range of the trigger switch 26. When the tape is taken, the adhesive force of the tape pressing shaft 11 will drive the tape pressing shaft 11 to rotate, and then drive the trigger induction sheet 25 to rotate, and trigger the switch 26 to generate a pulse signal.

[0086] S5, periodically inject lubricating oil into the oil suction filler 37 through the manual oil injection port 36 and the automatic oil injection port 16, and lubricate the surfaces of the scissor static blade 19 and the scissor moving blade 20 through the oil suction filler 37 to prevent the accumulated glue from affecting the tape output.

[0087] The above-described embodiments are only a preferred solution of the present application, and are not intended to limit the present application. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present application. Therefore, any technical solution obtained by equivalent replacement or equivalent transformation shall fall within the protection scope of the present application.

At the same time, the sealing mechanism (14) moves horizontally away from the tape pressing fixing seat (9) to open. The air outlet of the oil injection and air blowing fixing seat (12) blows air obliquely downward to make the tape adhere to the tape guide plate (5) for transportation, preventing the peeled tape head from being taken away along the rotation direction of tape conveyor b (7).
