[0026] Example 1
[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a tape supply device is generally used in packaging equipment for supplying tape. In this embodiment, it is installed in an automatic foil splicing device to supply tape to a pressing device 7, which uses the tape to glue the foil end to end. The tape supply device includes a frame 1 and a tape guide device 4 mounted on the frame 1. The tape guide device is used to guide the tape, specifically the tape roll 6, to a tape conveying device 3. The tape conveying device 3 is mounted on the frame 1 to receive the tape from the tape guide device 4 and convey it forward. A tape cutting device 5 is mounted on the frame 1 and located on one side of the tape guide device 4. The tape cutting device 5 is used to cut the tape output by the tape conveying device 3. After the tape conveying device 3 outputs the tape a certain distance, i.e., the length of the tape meets the splicing distance of the aluminum foil, the tape cutting device 5 is activated to cut the tape, and the pressing device 7 presses the cut tape to the splicing point of the aluminum foil. Preferably, the tape guiding device 4 and the tape cutting device 5 are mounted on the frame 1 via the mounting base 2.
[0028] In this embodiment, the tape conveying device includes a sliding guide device 31 mounted on the frame 1. A guide roller drive device 32 is mounted on the sliding guide device 31, and a guide roller 35 is mounted at the output end of the guide roller drive device 32. The sliding guide device 31 drives the guide roller drive device 32 to slide along its guiding direction, and the guide roller drive device 32 drives the guide roller 35 to receive the tape discharged from the tape guiding device 4. That is, under the drive of the guide roller drive device 32, one end of the tape adheres to the guide roller 35, and the tape slides forward via the sliding guide device 31, thus moving the tape forward.
[0029] In this embodiment, the sliding guide device 31 can be a rodless cylinder that converts the energy of compressed air into mechanical energy for linear motion, driving the load to perform linear reciprocating motion, such as the German FESTO linear drive. The sliding guide device 31 includes: a guide rail 311 mounted on the frame 1; a slider 312 slidably connected to the guide rail 311; and a position detection device 313 mounted on one side of the guide rail 311, used to detect the position of the slider 312. The position detection device 313 is not limited and can be a displacement sensor, a grating ruler, a proximity switch, etc. By installing the position detection device 313, we can accurately monitor the position of the slider 312, thereby determining the exact position of the guide roller 35. In this way, the guide roller 35 can accurately adhere the tape at a predetermined position and accurately deliver the tape to the target position.
[0030] In this embodiment, the guide roller driving device 31 includes: a cylinder 321 mounted on the slider 312; and a piston position monitoring device 322 mounted on one side of the cylinder 321, the piston position monitoring device 322 being used to detect the position of the cylinder piston to determine the position of the guide roller 35. The cylinder 321 is mounted on the slider 312 via a mounting plate 33.
[0031] In this embodiment, the output end of the guide roller drive device 32 is provided with a guide roller mounting base 34, on which a guide roller 35, an auxiliary roller 37 and a locking cylinder 36 are mounted. The locking cylinder 36 is used to lock the guide roller 35.
[0032] In this embodiment, the tape cutting device 5 includes a cutting drive device 51 mounted on the frame 1. The cutting drive device 51 can be a cylinder, an electric push rod, a motor, etc. A cutting blade rotor 52 is provided at the output end of the cutting drive device 51, and a cutting blade 53 is mounted on the cutting blade rotor 52. The cutting drive device 51 drives the cutting blade rotor 52 to rotate, thereby driving the cutting blade 53 to perform the tape cutting action. Preferably, the cutting blade rotor 52 is mounted on the mounting base 2 via a rotor fixing seat 55, and a bearing 54 is sleeved on the cutting blade rotor 52 to facilitate the rotation of the cutting blade rotor 52 and ensure that the cutting blade does not jam.
[0033] In this embodiment, the cutting drive device 51 includes a cutting cylinder 511 mounted on the frame 1, and the output end of the cutting cylinder 511 is connected to the cutting blade rotating rod 52 via a Y-shaped connecting rod 512.
[0034] In this embodiment, a limiting plate 56 is provided on the frame 1. The limiting plate 56 is installed on one side of the cutting blade 53 to limit the position of the cutting blade 53.
[0035] The beneficial effects of this embodiment are as follows: Through the coordinated action of the tape guiding device, conveying device, and cutting device, the entire process of tape production, conveying, and cutting is automated. The sliding guiding device uses a rodless cylinder (such as a FESTO linear actuator) combined with a position detection device to achieve precise positioning of the guide roller and long-stroke conveying, meeting the distance accuracy requirements for the splicing of the first and last ends of tin foil. The linear reciprocating motion of the slider and the linkage with the position detection device can precisely control the tape output length according to the tin foil splicing requirements, avoiding manual measurement errors and improving splicing efficiency. Through the cylinder and piston position monitoring device, the piston position monitoring device can provide real-time feedback on the position of the cylinder piston, ensuring that the guide roller accurately presses down to stick the tape and ensuring the stability of the tape sticking action. The cutting device uses a cylinder to drive the cutting blade rotor, combined with a limit plate and bearing structure, to achieve smooth and rapid cutting of the tape. The entire device improves space utilization through modular design, and combined with the automated control system, it can precisely control the tape length, reduce manual intervention, and significantly improve the efficiency and reliability of tin foil splicing, making it suitable for high-speed packaging scenarios.
[0036] Example 2
[0037] The difference between this embodiment and Embodiment 1 is that, in this embodiment, the tape guiding device 4 includes a tape mounting base 41 mounted on the frame 1, at least one tape guiding roller 42, and a tape adsorption device 44. The tape mounting base 41 is used to mount the tape roll 6; the tape guiding roller 42 is used to guide the tape to the tape adsorption device 44; and the tape adsorption device 44 is used to adsorb the tape so that the tape conveying device 3 can stably receive the tape.
[0038] The tape adsorption device 44 includes an adsorption device mounting base 441 mounted on a mounting base 2. An adsorption rack 442 is mounted on the adsorption device mounting base 441. The adsorption rack 442 has a cavity inside. An adsorption plate 443 is provided on the adsorption rack 442. A vacuum adsorption device is connected to the adsorption cavity through a connector. The adsorption plate 443 has through holes. The vacuum adsorption device evacuates the cavity, thereby adsorbing the tape onto the adsorption plate 443.
[0039] In this embodiment, a tape detection device 43 is provided on one side of the tape guide roller 42. The tape detection device 43 is used to detect whether the tape is being output. That is, when the tape on the tape roll 6 is used up, the tape detection device 43 can detect that there is no tape output. The tape detection device 43 transmits a signal to the control system, and the control system then sends a signal to the technician so that the technician can install a new tape roll.
[0040] The working principle or operation process in this implementation is as follows: When using the tape supply device, the technician first installs the tape roll 6 on the tape mounting base 41 and pulls the tape to the tape adsorption device 44; then, the vacuum adsorption device is activated, and a vacuum is drawn inside the cavity of the adsorption frame 442 to adsorb and fix the tape onto the surface of the adsorption plate 443. After the tape conveying device 3 is activated, the sliding guide device 31 drives the slider 312 to slide towards the tape adsorption device 44. When the position detection device 313 detects that the slider 312 has slid to the preset position, it transmits a signal to the control system. The control system then activates the cylinder 321, driving the guide roller 35 to move down to adhere the tape. After the tape is adhered, the slider 312 slides in the conveying direction. When the position detection device 313 detects that it has slid to the designated position, it transmits a signal to the control system again. The control system then triggers the cutting drive device 51 to start, driving the cutting blade rotor 52 to rotate, which in turn drives the cutting blade 53 to perform the tape cutting action.
[0041] The beneficial effects of this embodiment are as follows: By configuring a tape adsorption device, which utilizes vacuum adsorption technology to adsorb and fix the tape, and using guide rollers to ensure stable tape output, the vacuum adsorption function of the adsorption plate ensures the flatness and tension of the tape, preventing slackness or deviation during conveying. Through the cooperation of the guide rollers and the detection device, stable tape output can be ensured, and the tape output status can be monitored in real time. When the tape is exhausted, an automatic signal is triggered to feed back to the control system, reminding the user to replace the roll material, avoiding equipment idling or downtime due to material shortages, and improving the continuity of automated production.
