The upper part of the material film hatch 70 is embedded with an iron sheet, and the upper part of the cover tape collection bin 7 is provided with a magnet corresponding to the position of the iron sheet. The magnetic attraction to the iron sheet should be appropriate. If the attraction is too small, the cover tape collection bin 7 will be opened by the cover tape when it is not full of cover tape, increasing the workload of removing the cover tape; if the attraction is too large, the material film hatch 70 cannot be opened after the cover tape collection bin 7 is full of cover tape, causing the cover tape to overflow from the positions of the active recovery gear 621 and the passive recovery gear 622, and at the same time, the engagement degree of the active recovery gear 621 and the passive recovery gear 622 becomes smaller, so that the cover tape cannot be collected in time, thereby inducing a shutdown failure. A blade 73 is fixed to the material film hatch 70 by a screw. After the cover tape fills the cover tape collection bin 7, it will open the material film hatch 70 under the action of pressure. After cleaning the cover tape in the cover tape collection bin 7, the cover tape can be cut by sliding along the gap of the material film hatch 70 to the blade 73. The blade 73 is installed in a hidden manner, and under normal use, the user cannot touch the blade 73, so it is safe and convenient to use.

[0048] The integrated cover tape recovery mechanism realizes automatic recovery of the tape cover tape through the cover tape recovery enabling device. The recovery drive motor 61 drives the active recovery gear 621 and the passive recovery gear 622 to engage and cooperate to recover the cover tape. The recovery pressure arm 63 maintains an elastic engagement tendency under the action of the compression spring 632, ensuring that the cover tape is stably wound to the cover tape collection bin during the conveying process. The material film hatch 70 is provided with a guide block 72 with a blade 73, which can cut the cover tape when opened, without the need to carry a cutting tool, and is convenient to use.

[0049] The above is only the preferred embodiment of the present application. For those skilled in the art, according to the idea of the present application, the specific implementation and application range can be changed, and the content of the specification should not be understood as a limitation of the present application.
