[0002] The main raw materials of rubber composite cables include conductors, insulation layers, sheaths, etc., among which the cable sheath is made of composite rubber materials. In the production of composite rubber, rubber raw material particles, plasticizers, processing aids and other raw materials need to be mixed. When mixing rubber, rubber raw material particles, plasticizers, processing aids and other raw materials need to be transported through a feeder.

[0003] When conveying raw materials such as rubber raw material particles, plasticizers, processing aids, etc., the feeder in the prior art usually needs to add the raw materials into a funnel, and enter the feed barrel through the funnel, and the raw materials are fed by a spiral propulsion screw. However, in the process of the raw materials entering the feed barrel from the funnel, due to the reduction of the feed port, when a large amount of raw materials accumulate at the feed port, the feed port will be blocked, which will affect the normal conveying of the raw materials. At the same time, the raw materials will accumulate more and more in the funnel, eventually leading to leakage of the raw materials, which not only causes waste of raw materials, but also reduces the conveying efficiency of the raw materials.

The driving frame 65 includes a vertical block 651 and a vertical slide groove 652 provided on the outer wall of the inner end of the vertical block 651. A horizontal slider 653 is fixedly installed on the top of the vertical block 651, and the horizontal slider 653 is slidably arranged in the bottom slide groove 671 through a ball bearing, and the vertical slider 633 is slidably arranged in the vertical slide groove 652 through a ball bearing. A deformed connecting rod 654 is fixedly installed on the outer wall of one side of the vertical block 651, and a circular ring 655 is fixedly installed at the upper end of one end of the deformed connecting rod 654. The clamping block 66 includes an installation center shaft 661 and driving card blocks 662 respectively fixedly installed at both ends of the installation center shaft 661, and the circular ring 655 is rotatably sleeved on the outer periphery of the installation center shaft 661, and the circular ring 655 is rotatably arranged between the driving card blocks 662 through a ball bearing.

[0026] Specifically, by setting the bottom slide groove 671 and the vertical slide groove 652, the card-connecting push column 63 can be tilted and slid while the card-connecting block 66 can be driven by the driving frame 65 to slide horizontally, thereby achieving the driving effect of driving the card block 662 to be engaged into the first card groove 751, cleverly realizing the decomposition of the displacement direction and ensuring the dredging process.

[0027] The anti-blocking component 7 includes a mounting shell 71 and a clearing plate 72 rotatably arranged in the inner cavity of the square through hole 221. The mounting shell 71 is fixedly mounted at the outer opening of the square through hole 221. A gear shaft 73 is fixedly mounted on the outer wall of one end of the clearing plate 72. An L-shaped connecting rod 74 is fixedly mounted on the outer wall of one end of the mounting shell 71. A first connecting gear 75 is rotatably mounted on the inner outer wall of the inner end of the L-shaped connecting rod 74. A second connecting gear 76 is rotatably mounted on the inner outer wall of one end of the mounting shell 71. The second connecting gear 76 is meshingly connected with the gear shaft 73, and the first connecting gear 75 is meshingly connected with the upper end of the transmission belt 8.

[0028] A first card slot 751 is provided on the inner outer wall of the first connecting gear 75, and a second card slot 761 is provided on the inner outer wall of the second connecting gear 76. In the initial state, the driving card block 662 located at the other end of the mounting center axis 661 is slidably engaged in the second card slot 761, and the driving card block 662 located at one end of the mounting center axis 661 is arranged at the outside of the opening of the first card slot 751.

[0029] Specifically, when the feed port 11 and the lower cylinder 21 are blocked, the raw materials will accumulate more and more in the funnel 2. When the raw materials overflow the square slider 62, there will be an extrusion force on the square slider 62, so that the square slider 62 is pushed to slide along the square slide hole 222 to the inner cavity of the open convex box 61. In this process, the square slider 62 will drive the card-connecting push column 63 to slide outward as a whole, and the card-connecting push column 63 will push the driving frame 65 to move to one end, and the driving frame 65 will drive the card-connecting block 66 to move to one end together, so that the card-connecting push column 63 at one end of the installation center axis 661 is located at the bottom of the square slider 62. The driving block 662 is engaged with the first slot 751, and the driving motor 3 drives the connecting shaft 5 to rotate. The connecting shaft 5 drives the first connecting gear 75 to rotate through the transmission belt 8. The first connecting gear 75 drives the second connecting gear 76 to rotate through the engaging block 66. The second connecting gear 76 drives the dredging plate 72 to rotate through the gear shaft 73, thereby achieving the dredging of the blocked position. The whole process is automatic, and the gravity of the raw material itself is cleverly used as the starting force, which prevents the waste of raw materials and the low feeding efficiency caused by the blockage of raw materials. Furthermore, after the raw material is cleared, the square slider 62 will gradually lose the pressure of the raw material. At this time, under the elastic force of the reset spring 621, it will drive the driving block 662 to separate from the first slot 751, so that the clearing plate 72 is reset to the square through hole 221 under the continuous downward impact of the raw material, ensuring that the clearing plate 72 will not affect the normal passage of the raw material.

[0030] In order to solve the technical problem of how to conveniently start the dredging plate 72 manually, as Figure 5-Figure 9 As shown, the following preferred technical solutions are provided: The snap-on push column 63 includes a sliding cylinder 631 and a square plug block 632 fixedly installed on the inner end of the sliding cylinder 631, and the other end of the sliding cylinder 631 is rotatably connected to a vertical slider 633, and an outer peripheral sliding groove 634 is provided on an outer wall on one side of the outer periphery of the sliding cylinder 631, and an L-shaped sliding hole 635 is provided on the inner wall at the inner end of the inner cavity of the outer peripheral sliding groove 634, and the other end of the L-shaped sliding hole 635 is connected to and provided on an outer wall on one side of the square plug block 632.

[0031] The elastic block 64 includes a pressing block 641 and an L-shaped block 642 fixedly installed on the outer wall of the inner end of the pressing block 641. The inner end of the L-shaped block 642 is clamped in the square slot 623, so that the square plug block 632 can be clamped and fixed in the square slot 622, and the pressing block 641 is elastically slidably installed in the peripheral slide groove 634 through the connecting spring 643.

[0032] Specifically, when the feeder needs to be forced to start the unblocking operation, the staff can squeeze the pressing block 641 by hand, and the pressing block 641 will drive the L-shaped block 642 to slide inward together. During this process, one end of the L-shaped block 642 will be separated from the square slot 623. At this time, the staff pushes the card push column 63, and the card block 66 can be directly driven by the driving frame 65 to be engaged in the first slot 751, thereby achieving the driving effect of the unblocking plate 72. At the same time, it also ensures that the unblocking plate 72 can have a continuous unblocking effect without the staff continuously pushing the card push column 63, and it has high adaptability.

[0033] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
