Die cutting device with adjustable punching distance

Abstract

According to the die cutting device with the adjustable punching spacing, each incomplete gear drives a conveying device to rotate by a certain angle in a rotation period, so that an adhesive tape is fed by a certain length from a raw material end to a finished product end, but due to the fact that the tooth numbers of the incomplete gears are different, the punching spacing is adjustable. The rotation angles of the conveying device driven by the incomplete gears in one rotation period are different, so that the feeding lengths of the adhesive tapes are different; and meanwhile, the transmission shaft continuously drives the blanking device to move in the rotation period, so that the blanking device cuts the adhesive tape in a static state. Therefore, a user can move the moving shaft to enable any incomplete gear to be meshed with the conveying device, so that the feeding length of the adhesive tape in a rotation period is changed, the blanking rule of the blanking device is not changed, and the punching interval is controllable.

DETAILED DESCRIPTION

[0035] Combine the following Figure 1-9 The utility model is described in detail.

[0036] A die-cutting device with adjustable punching spacing includes a box body 10, a work surface 20 is provided in the box body 10, a punching device, a conveying device, a speed change device and a motor (not shown) are also provided in the box body 10, specifically:

[0037] The punching opening 201 is provided on the work surface 20. The punching opening 201 cooperates with the punching device to cut the tape 60. A collecting bucket is provided below the punching opening 201 to collect cutting waste. The conveying device is used to move the tape 60 from the raw material end to the finished product end. The raw material end and the finished product end are respectively located at the two ends of the punching opening 201.

[0038] A speed change device is also provided in the box body 10, including a transmission shaft 501 and a moving shaft 502 provided on the work surface 20, and the work surface 20 is provided with a pivot seat 505, and the transmission shaft 501 and the moving shaft 502 are pivotally connected to the pivot seat 505. The transmission shaft 501 and the moving shaft 502 are coaxially connected to each other, and the moving shaft 502 can move relative to the transmission shaft 501. The transmission shaft 501 is transmission-connected to the punching device, and the moving shaft 502 is provided with a plurality of incomplete gears 503 having the same pitch circle diameter and module, and each incomplete gear 503 is arranged in sequence with the number of teeth gradually increasing or decreasing.

[0039] When in use, each incomplete gear 503 will drive the conveyor to rotate a certain angle within a rotation cycle, thereby feeding the tape 60 from the raw material end to the finished product end by a certain length. However, due to the different number of teeth set on each incomplete gear 503, the angles at which each incomplete gear 503 drives the conveyor to rotate within a rotation cycle are different, and thus the feeding lengths of the tape 60 are also different. At the same time, the transmission shaft 501 will continue to drive the punching device to move within the rotation cycle, so that the punching device cuts the stationary tape 60. Therefore, the user can move the moving shaft 502 to make any incomplete gear 503 mesh with the conveyor, thereby changing the feeding length of the tape 60 within a rotation cycle, but does not change the punching law of the punching device, thereby achieving controllable punching spacing.

[0040] In this embodiment, the conveying device includes a first rotating part and a second rotating part that are mutually transmission-connected, and the surfaces of the first rotating part and the second rotating part abut against each other to clamp the adhesive tape 60, so that the adhesive tape 60 moves from the raw material end to the finished product end, and any incomplete gear 503 is transmission-connected to the first rotating part or the second rotating part. The first rotating part includes a first rotating roller 401 and an elastic layer 403 sleeved on the surface of the first rotating roller 401, and the second rotating part includes a second rotating roller 402 and an elastic layer 403 sleeved on the surface of the second rotating roller 402. The two elastic layers 403 clamp the adhesive tape 60 to prevent the adhesive tape 60 from being damaged during the feeding process.

[0041] In this embodiment, the first rotating roller 401 or the second rotating roller 402 is provided with an input gear 100, and the input gear 100 is meshed with the incomplete gear 503, so that the input gear 100 is driven by the incomplete gear 503, and then the first rotating roller 401 or the second rotating roller 402 is driven to rotate. Furthermore, the teeth of the incomplete gear 503 are 3-5 mm thicker than the teeth of the input gear 100, which is used to accommodate the meshing error caused by the axial displacement when the movable shaft 502 rotates, and avoid the input gear 100 from meshing with two incomplete gears 503 at the same time. A sensor for monitoring the number of rotations of the first rotating roller 401 or the second rotating roller 402 is provided on the side surface. When the sensor detects that the first rotating roller 401 or the second rotating roller 402 has reached the preset number of rotations, the sensor sends a signal to the control system, and the control system stops the motor from rotating and emits a prompt sound to remind the staff that the cutting is completed.

A plurality of annular fixing grooves 5022 are provided on the outer surface of the other end of the moving shaft 502, and the distance between each annular fixing groove 5022 is equal to the displacement amount of switching from one incomplete gear 503 to another incomplete gear 503. Therefore, the operator can know which incomplete gear 503 is currently in meshing state by observing the annular fixing groove 5022.

[0043] In this embodiment, the work table 20 is provided with a limit frame 506, and the transmission shaft 501 is provided with an annular fixed groove 5022 at one end which is pivotally connected to the limit frame 506. The limit frame 506 is threadedly matched with a plurality of limit pins 507. The length of the limit pins 507 is adjusted so that the head of the limit pin 507 is located in the annular fixed groove 5022, thereby limiting the axial movement of the transmission shaft 501.
