Technical Field
[0001] The utility model relates to the technical field of wire-releasing devices, in particular to an active wire-releasing device for a tin strip roll. Background Art
[0002] During the processing of tin sheets, the rolled tin ribbon needs to be hung on a pay-off mechanism, which then pays out the tin ribbon and introduces it into a cutting mechanism to be cut into tin sheets. If a passive pay-off mechanism is used, the tin ribbon needs to pull the tin ribbon roll to rotate during the passive pay-off process. However, the tin ribbon is soft in texture and is easily deformed after being pulled, resulting in unqualified quality of the tin sheet produced. If an active pay-off mechanism is used, it is difficult to control the pay-off rate of the tin ribbon. In view of the above problems, an active pay-off device for tin ribbon roll is proposed.

[0005] Furthermore, the pay-off rack is provided with a slide rail, and the light movable block is slidably arranged on the slide rail, and the light movable block is pushed to slide along the slide rail during the process of gradually tightening the loosened tin strip.
[0006] Furthermore, the slide rail is arranged vertically, and the lightweight movable block can be raised and lowered and slid on the slide rail; the loose tin ribbon passes around the lightweight movable block from the bottom of the lightweight movable block; the loose tin ribbon pushes the lightweight movable block upward during the process of gradually tightening; after the gradually tightened tin ribbon is relaxed, the lightweight movable block moves downward and resets under the action of gravity.
[0007] Furthermore, a reset stopper is provided on the slide rail, and the lightweight movable block abuts against the reset stopper when being reset along the slide rail.
[0008] Furthermore, the sensor is an infrared detector, and when the lightweight movable block is reset to abut against the reset block, the lightweight movable block correspondingly blocks the infrared detector.

BRIEF DESCRIPTION OF THE DRAWINGS
[0013] Attached Figure 1 It is a schematic diagram of the tin ribbon released from the tin ribbon roll in a relaxed state;
[0014] Attached Figure 2 This is a schematic diagram of the tin ribbon being released from the tin ribbon roll and about to be tightened. DETAILED DESCRIPTION
[0015] The utility model is further described below in conjunction with the accompanying drawings.
[0016] As attached Figures 1 to 2 The active unwinding device for a tin ribbon roll comprises a unwinding frame 1 and an induction frame 2; a tin ribbon roll 3 is arranged on the unwinding frame 1, and the tin ribbon roll 3 rotates when driven by a driving mechanism, thereby causing the tin ribbon roll 3 to unwind a tin ribbon 4. In one embodiment, the unwinding tin ribbon 4 is introduced into a cutting mechanism, and the tin ribbon 4 is cut into tin sheets.
[0017] The induction frame 2 has a light movable block 5 and a sensor 6. The light movable block 5 can be moved on the induction frame 2, and the sensor 6 can sense the movement of the light movable block 5 on the induction frame 2. The loose tin ribbon 4 released from the tin ribbon roll 3 bypasses the light movable block 5. As the cutting mechanism consumes the tin ribbon 4, the loose tin ribbon 4 will gradually tighten. In the process of the loose tin ribbon 4 gradually tightening, the tin ribbon 4 will gradually stick to the light movable block 5, and finally push the light movable block 5, so that the light movable block 5 moves on the induction frame 2. Since the mass of the light movable block 5 itself is small, the force required for the tin ribbon 4 to push the light movable block 5 is small, and it is not easy to cause the tin ribbon 4 to deform.
[0018] The sensor 6 is electrically connected to the driving mechanism. When the sensor 6 senses the displacement of the light movable block 5 on the sensing frame 2, the sensor 6 sends a signal to the driving mechanism, which starts working and drives the tin ribbon roll 3 to release the tin ribbon 4, thereby relaxing the gradually tightened tin ribbon 4, thereby preventing the tin ribbon 4 from being completely tightened, and the tin ribbon 4 will not be deformed due to being completely tightened. In this way, the unwinding rate of the tin ribbon roll 3 is controlled, and the consumption of the tin ribbon 4 by the cutting mechanism can be automatically adapted.
[0019] The pay-off frame 1 is provided with a slide rail 7, on which a light movable block 5 is slidably arranged, and in the process of gradually tightening the loosened tin ribbon 4, the light movable block 5 is pushed to slide along the slide rail 7. The force required by the tin ribbon 4 to push the light movable block 5 to slide along the slide rail 7 is small, and the tin ribbon 4 is not easily deformed.
[0020] As attached Figure 1 and 2 As shown in , the slide rail 7 is arranged vertically, and the light movable block 5 can slide up and down on the slide rail 7. Accordingly, the loose tin ribbon 4 bypasses the light movable block 5 from below. In the process of the loose tin ribbon 4 being gradually tightened, the tin ribbon 4 will push the light movable block 5 to move upward. After the gradually tightened tin ribbon 4 is relaxed, the light movable block 5 moves down along the slide rail 7 under the action of gravity, so that the light movable block 5 is reset.
[0021] The slide rail 7 is provided with a reset block 8, and the light movable block 5 abuts against the reset block 8 when it is reset along the slide rail 7. Since the reset block 8 blocks the light movable block 5, when the tin ribbon 4 is in a relaxed state, the tin ribbon 4 and the light movable block 5 are separated from each other, and the gravity of the light movable block 5 will not be applied to the tin ribbon 4, and it is not easy to cause the tin ribbon 4 to deform.
[0022] The sensor 6 is an infrared detector. When the light movable block 5 is reset to abut against the reset block 8, the light movable block 5 blocks the infrared detector accordingly. The driving mechanism is a motor 12, and the electric output shaft drives the tin ribbon roll 3 to rotate. When the tin ribbon 4 pushes the light movable block 5 to move upward, the infrared detector can sense the displacement of the light movable block 5, thereby transmitting an electrical signal to the motor 12, so that the motor 12 drives the tin ribbon roll 3 to rotate, so that the tin ribbon roll 3 releases the tin ribbon 4.
[0023] The slide rail 7 is composed of two parallel sliding guide rods 9, and two sliding guide holes are respectively opened at both ends of the light movable block 5, and the two sliding guide holes are respectively slidably matched with the two sliding guide rods 9. A belt-passing gap 10 is formed between the two sliding guide rods 9, and the tin ribbon 4 released from the tin ribbon roll 3 passes through the belt-passing gap 10 accordingly. The two sliding guide rods 9 play a role of limiting, limiting the tin ribbon 4 within the belt-passing gap 10, so that the light movable block 5 will inevitably be pushed upward during the gradual tightening of the tin ribbon 4.
[0024] The light movable block 5 is sleeved with a rolling sleeve 11, which is in a rod shape and can rotate on the light movable block 5. The rolling sleeve 11 is located in the belt gap 10, and the loose tin strip 4 can be abutted against the rolling sleeve 11 during the process of being gradually tightened, and the tin strip 4 rolls with the rolling sleeve 11 to reduce friction.
[0025] Combined with Figure 1 and 2 The working method of the utility model is described as follows: the tin ribbon 4 released from the tin ribbon roll 3 passes through the strip gap 10 and is introduced into the cutting mechanism, and the tin ribbon 4 passes under the light movable block 5. In the initial state, as shown in the attached Figure 1 As shown in FIG. 1 , the tin ribbon 4 is in a relaxed state, and as the cutting mechanism consumes the tin ribbon 4, the tin ribbon 4 will gradually tighten; Figure 2 As shown in the figure, as the tin ribbon 4 is gradually tightened, the tin ribbon 4 will push the lightweight movable block 5 to move upward along the slide rail 7, so that the lightweight movable block 5 no longer blocks the infrared detector; but in the process of the tin ribbon 4 pushing the lightweight movable block 5 to move upward, the tin ribbon 4 will not be completely tightened; and after the infrared detector senses the upward movement of the lightweight movable block 5, the infrared detector sends a signal to the motor 12, and the motor 12 drives the tin ribbon roll 3 to rotate and release the tin ribbon 4, so that the gradually tightened tin ribbon 4 is relaxed again, and the lightweight movable block 5 falls back under the action of gravity, and this cycle is repeated, so that the rate at which the tin ribbon roll 3 releases the tin ribbon 4 can adapt to the consumption of the tin ribbon 4 by the cutting mechanism.
[0026] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
