DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0021] In addition, the descriptions of "first", "second", etc. in the present invention are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0022] In the description of the embodiments, unless otherwise clearly specified and limited, the terms "disposed", "connected" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or it can be connected through an intermediate medium, or it can be a communication between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0023] like Figure 1 As shown, the anti-stick knife rubber strip metal removal device in this embodiment includes a front bracket 1, a rear bracket 2, a front conveyor belt 3, a rear conveyor belt 4, a swing mechanism 5, a metal detector 6 and a cutting mechanism 7. The front bracket 1 is adjacent to the rear bracket 2, the front conveyor belt 3 is obliquely arranged on the front bracket 1, the rear conveyor belt 4 is obliquely arranged on the rear bracket 2, and the front conveyor belt 3 and the rear conveyor belt 4 are connected by the swing mechanism 5.

[0024] The metal detector 6 is arranged on the rear conveyor belt 4 to detect whether the rubber strip contains metal. The metal detector 6 can adopt conventional technical means in the art.

[0025] The cutting mechanism 7 is arranged on the rear conveyor belt 4 and is located between the swing mechanism 5 and the metal detector 6 .

[0026] The front conveyor belt 3 is provided with a first rubber pressing roller 8, and the front and rear ends of the rear conveyor belt 4 are respectively provided with a second rubber pressing roller 9 and a third rubber pressing roller 10, and a guide roller 11 is further provided on the rear side of the third rubber pressing roller 10. The rear conveyor belt 4 drives the rubber strip to move forward, and the rubber strip enters through the guide roller 11. The third rubber pressing roller 10 presses downward under the action of gravity, thereby pressing the rubber strip flat for subsequent inspection and cutting.

[0027] like Figure 2As shown, the cutting mechanism 7 includes a cutter 71, a cutter drive motor 72, an air intake shaft 73 and an air blowing nozzle 74. The cutter 71 is arranged above the rear conveyor belt 4 through a cutter bracket 75. The cutter drive motor 72 is arranged on one side of the cutter bracket 75 and is transmission-connected to the cutter 71 through the air intake shaft 73. The air blowing nozzle 74 is arranged on one side of the cutter 71 and is connected to the air intake shaft 73.

[0028] The air inlet shaft 73 is a hollow tubular structure, and an air inlet 76 is provided at one end. The air inlet 76 is externally connected to a high-pressure air source and supplies air to the blowing nozzle 74 through the air inlet shaft 73 .

[0029] The cutter drive motor 72 drives the cutter 71 to rotate, thereby cutting the rubber strip. During the cutting process, the air blowing nozzle 74 blows air at the same time to blow off the rubber material adhering to the cutter 71, preventing the rubber strip from adhering to the cutter 71 and then affecting the subsequent cutting work, thereby improving the production quality of subsequent products.

[0030] like Figure 3-4 As shown, the swing mechanism 5 includes a roller frame 51, a transition plate 52 and a swing cylinder 53. One end of the roller frame 51 is rotatably connected to the rear conveyor belt 4. The transition plate 52 is arranged at a position between the roller frame 51 and the rear conveyor belt 4. The swing cylinder 53 is arranged at the bottom of the rear conveyor belt 4, and one end is rotatably connected to the rear bracket 2, and the other end is rotatably connected to the roller frame 51.

[0031] The transition plate 52 provides guidance for the movement of the rubber strip, and the swing cylinder 53 can drive the roller frame 51 to swing up and down. If the rubber strip contains metal impurities, the roller frame 51 swings downward to export the rubber strip waste with metal; if there are no metal impurities, the roller frame 51 is lifted up and maintained on the same conveying plane with the front conveyor belt 3 and the rear conveyor belt 4, so as to continuously convey the rubber strip forward.

[0032] The above is only a preferred embodiment of the utility model, and is not intended to limit the utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in the field to implement; when the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the utility model.
