Description

Technical Field

[0001] The present application relates to the field of tape slitting machines, and in particular to a waste edge collecting device for tape slitting machines. Background Art

[0002] The tape slitting machine is a mechanical device used to slit large rolls of tape into small rolls. During the slitting process, some waste edges will be generated. If these waste edges are not collected and processed in time, it will not only affect the production environment, but also cause a waste of resources.

[0003] At present, the waste edge collection device of the tape slitting machine usually adopts the suction method to suck the waste edges into the pipe, but this method has some problems. The waste edges are affected by the wind, and the release paper may be separated from the base tape, so that the adhesive on the base tape is exposed, which causes the base tape to stick to the inner wall of the pipe. Due to the limited space inside the pipe and the inability to see the internal situation of the pipe, it brings inconvenience to the cleaning operation. Utility Model Content

[0004] In order to improve the problem that the base tape sticks to the inner wall of the pipe, which is limited by the limited space inside the pipe and the internal situation of the pipe cannot be seen clearly, causing inconvenience in the cleaning operation, the present application provides a waste edge collection device for a tape slitting machine.

[0005] The waste edge collection device of a tape slitting machine provided in the present application adopts the following technical solution:

[0006] A waste edge collecting device for a tape slitting machine comprises a frame, a blower and an air duct;

[0007] One end of the air duct is connected to the air outlet of the blower, and the other end passes through the frame, and both ends of the air duct along the axial direction are provided with feed ports;

[0008] The air duct is provided with a cleaning groove extending along its axial direction, and the cleaning groove is located between the two feeding ports. The air duct is provided with a baffle for covering the cleaning groove, and the baffle is fitted with the outer circumferential surface of the air duct. The air duct is provided with two slip rings corresponding to the two ends of the cleaning groove respectively, and the two opposite sides of the two slip rings are provided with coaxially distributed annular grooves, the baffle is provided with a sliding groove for inserting the slip ring, and both ends of the baffle are threadedly connected with limit screws inserted into the annular grooves.

[0009] By adopting the above technical solution, the waste edges are transmitted into the air duct from the feed port, and the wind force of the blower transmits the waste edges from the air duct to the outside of the frame; when cleaning is required, the operator loosens the limit screw and turns the baffle to open the cleaning slot to expose the stuck waste edges, making cleaning convenient and quick.

[0010] Optionally, a positioning ring is provided on the limit screw, and a positioning plate is provided at the end of the baffle. When the positioning ring abuts against the positioning plate, the end of the limit screw is located between the bottom of the annular groove and the notch.

[0011] By adopting the above technical solution, the positioning plate limits the separation of the limit screw and the ring groove, so that the baffle plate maintains a sliding fit relationship with the slip ring, thereby avoiding the baffle plate from falling off.

[0012] Optionally, the positioning sheet is elastic.

[0013] By adopting the above technical solution, when the limit screw needs to be screwed out, the positioning piece can be deformed to make way for the limit screw.

[0014] Optionally, a circle of sealing strip is embedded on the side of the baffle plate facing the air duct, and the sealing strip is located outside the cleaning groove.

[0015] By adopting the above technical solution, the sealing strip increases the sealing between the baffle and the air duct, thereby ensuring the wind strength in the air duct.

[0016] Optionally, a panel is fixed to the air outlet of the blower, and a branch pipe communicating with the interior of the blower is provided on the panel, and the branch pipe is inserted into the air duct.

[0017] By adopting the above technical solution, the branch pipe realizes the connection between the air duct and the air outlet of the blower, so that the air duct and the air outlet of the blower are adapted in shape.

[0018] Optionally, the air duct is provided with an ear plate, and the ear plate is fixed to the panel by screws.

[0019] By adopting the above technical solution, a detachable connection between the air duct and the panel is achieved, which is convenient for replacement and maintenance.

[0020] Optionally, the ear plate is provided with a long waist hole for the screw to pass through, and a washer is sleeved on the screw, and the outer diameter of the washer is larger than the width of the long waist hole.

[0021] By adopting the above technical solution, the long waist hole provides a certain deviation margin for the threaded connection between the screw and the panel; the washer increases the contact area between the screw and the ear plate, ensuring effective tightening of the screw and the ear plate.

[0022] Optionally, the air duct is provided with a guide plate extending from the feed inlet into the air duct, and the guide plate is inclined toward the air outlet direction of the air duct.

[0023] By adopting the above technical solution, the guide plate plays a guiding role, reducing the possibility of the tape and the feed port getting stuck.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. By opening a cleaning slot on the air duct and setting a sliding baffle, the inside of the air duct can be exposed, making it easier to clean the inside of the air duct;

[0026] 2. The guide plate can better guide the waste edges into the air duct to improve the collection efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
