DETAILED DESCRIPTION

[0019] The specific implementation scheme of the utility model is described in detail below in conjunction with the accompanying drawings.

[0020] like Figure 1~Figure 4The scraping wire waste shearing device shown includes a base 1, a stand 2 is vertically arranged on the base 1, an adjacent conveying device 4 and a wire cutting device 3 are arranged on one side of the stand 2, an upper cutter disc 33 and a lower cutter disc 34 are synchronously rotatably arranged on the outer side of the wire cutting device 3, and a plurality of cutter heads 39 are evenly distributed along the circumference on the upper cutter disc 33 and the lower cutter disc 34 respectively, and the plurality of cutter heads 39 are distributed on the outermost circumference of the virtual tangent of the upper cutter disc 33 and the lower cutter disc 34. When rotating synchronously, the cutter heads 39 corresponding to the upper cutter disc 33 and the lower cutter disc 34 can contact at the tangent point to intermittently cut the scraping wire 6 conveyed by the conveying device 4.

[0021] Specifically, the conveying device 4 continuously transports the scraping wire 6 forward, and the upper and lower cutter discs 33 and 34 rotate synchronously. When the upper and lower cutter heads 39 are engaged, the scraping wire 6 is cut, so that the scraping wire 6 is broken into sections and falls down, completing the automatic processing of the broken wire of the scraping wire 6.

[0022] like Figure 1 The upper cutter disc 33 and the lower cutter disc 34 are respectively provided with three cutter heads 39 evenly distributed on the circumference. The three cutter heads 39 can cut the scraping wire 6 into broken wires of reasonable length. The cutter heads 39 are located on the outermost circumference of the upper cutter disc 33 and the lower cutter disc 34. When the upper cutter disc 33 and the lower cutter disc 34 rotate, the circumferential surfaces of the closest positions in the middle that are not located at the positions of the cutter heads 39 are separated and do not contact, so that the scraping wire 6 is continuously transported forward. When the upper and lower cutter heads 39 overlap, the scraping wire 6 is cut.

[0023] like Figure 1 and Figure 3 The upper baffle plate 31 is provided on one end surface of the upper blade disc 33, and the lower baffle plate 32 is provided on the other end surface of the lower blade disc 34. The upper baffle plate 31 and the lower baffle plate 32 block the end surfaces of the upper and lower blade heads 39 at the tangent position. The upper baffle plate 31 provided on the upper blade disc 33 and the lower baffle plate 32 provided on the lower blade disc 34 respectively block the end surfaces of the upper and lower blade heads 39 at the occlusal position, thereby preventing the scraping wire 6 from deviating from the upper blade disc 33 and the lower blade disc 34 during transportation, and thus failing to complete wire breaking.

[0024] Furthermore, the conveying device 4 includes an upper pressing wheel 41 and a lower pressing wheel 42 arranged with their wheel surfaces abutting against each other, the top of the lower pressing wheel 42 abuts against the bottom of the upper pressing wheel 41, the scraping wire 6 passes through the abutting surface between the upper pressing wheel 41 and the lower pressing wheel 42, the lower pressing wheel 42 is elastically arranged on the base 1 along the vertical direction, and the shaft transmission of the upper pressing wheel 41 is connected to the pneumatic motor 46. When the pneumatic motor 46 drives the upper pressing wheel 41 to rotate, the upper pressing wheel 41 drives the lower pressing wheel 42 to rotate synchronously, and the scraping wire 6 is squeezed and driven by the synchronously rotating upper pressing wheel 41 and the lower pressing wheel 42 to be transported.

[0025] A guide wheel 43 is also provided upstream of the lower pressure wheel 42, and a conduit 5 for the scraping wire 6 to pass through is horizontally provided between the conveying device 4 and the wire breaking device 3, and the conduit 5 is provided with a bell mouth on one side facing the conveying device 4. The conduit 5 serves as a connection between the conveying device 4 and the wire breaking device 3, so that the scraping wire 6 can be conveyed smoothly.

[0026] The two ends of the central axis of the lower pressure wheel 42 are arranged on the top of the corresponding spring 44, the bottom of the two springs 44 are arranged on the fixed seat 45, the fixed seat 45 is arranged on the base 1, and a vertical guide rod is arranged inside the spring 44 on the fixed seat 45. In this way, the lower pressure wheel 42 can be stably abutted against the bottom of the upper pressure wheel 41, so that the conveying of the scraping wire 6 is stable.

[0027] like Figure 3 The upper cutter disc 33 and the lower cutter disc 34 are fixedly sleeved on the corresponding transmission shafts 37. The transmission shaft 37 of the upper cutter disc 33 is connected to the motor 38 for transmission. A transmission box 35 is also provided on the transmission shaft 37 between the stand 2 and the wire breaking device 3. The two transmission shafts 37 are respectively sleeved with gears 36 in the transmission box 35. The upper cutter disc 33 and the lower cutter disc 34 rotate synchronously by meshing the two gears 36.

[0028] The working process of the utility model is as follows:

[0029] As shown in Figures 1-4, first, the scraping wire 6 is passed through the guide wheel 43, between the upper pressure wheel 41 and the lower pressure wheel 42, the conduit 5, the upper cutter disc 33 and the lower cutter disc 34 in sequence, and then the pneumatic motor 46 and the motor 38 are started, the scraping wire 6 is continuously transported, and finally, the upper cutter disc 33 and the lower cutter disc 34 intermittently cut the scraping wire 6.

[0030] The above embodiments are only illustrative of the principles and effects of the invention of the utility model, as well as some embodiments of its application, and are not intended to limit the invention of the utility model. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the invention, and all of these belong to the protection scope of the invention.
