DETAILED DESCRIPTION

[0032] In order to make the purpose, technical scheme and advantages of the utility model more clearly show, the following will combine the drawings to make the embodiment of the utility model further detailed description.

[0033] Figures 1-3 is a structure view of the briquetting machine convenient to disassemble of the utility model, as shown in Figures 1-3 The briquetting machine ring die includes annular lower plate of ring die 1 (the structure of lower plate of ring die 1 is shown in Figure 4The plurality of ring die inserts 21 (structure of the ring die insert 21 is shown in Figure 5 The plurality of ring die inserts 21 are assembled on the upper surface of the ring die lower plate 1 into a ring-shaped ring die body 2, and each ring die insert 21 is detachably fixedly installed on the upper surface of the ring die lower plate 1 through a fastening assembly 3.

[0034] As shown in Figures 6-8 The fastening assembly 3 includes a top cover 31 capable of being pressed against the upper surface of the ring die insert 21, a fastening rod 32 fixedly connected below the top cover 31, a ring die insert through hole 211 opened on the ring die insert 21, and a ring die lower plate through hole 11 (shown in Figure 4 ) opened on the ring die lower plate 1 corresponding to the ring die insert through hole 211, the fastening rod 32 is threaded through the ring die insert through hole 211 and the ring die lower plate through hole 11, a screw sleeve 33, a spring 34, and a screw sleeve top cover 35 are sleeved on the fastening rod 32, wherein the spring 34 is arranged between the top cover 31 and the screw sleeve 33 (i.e. the upper end of the spring 34 is connected with the top cover 31, and the lower end is connected with the screw sleeve 33), the screw sleeve top cover 35 is arranged below the screw sleeve 33, a rectangular guide rail hole 212 (shown in Figure 5 ) is opened on the lower surface of the ring die insert 21, the rectangular guide rail hole 212 is in communication with the ring die insert through hole 211, a rectangular plate 331 (shown in Figure 7 , Figure 9 ) capable of being embedded in the rectangular guide rail hole 212 is fixedly arranged on the upper end of the screw sleeve 33, and the screw sleeve 33 can slide up and down in the rectangular guide rail hole 212, the screw sleeve 33 has a screw sleeve screw structure 332 (shown in Figure 9 ) on the lower end, the screw sleeve top cover 35 has a screw sleeve top cover screw structure 351 (shown in Figure 9 ) on the upper end, the screw sleeve top cover screw structure 351 can be embedded with the screw sleeve screw structure 332, a tail plate 321 capable of being pressed against the lower surface of the screw sleeve top cover 35 is fixedly installed on the lower end of the fastening rod 32, the screw sleeve top cover 35 is pressed against the lower surface of the ring die lower plate 1 through the tail plate 321 of the fastening rod 32, a disassembly through hole 352 (shown in Figure 9 ) is opened on the screw sleeve top cover 35 for the tail plate 321 to pass through, the shape of the disassembly through hole 352 matches the shape of the tail plate 321.

[0035] When the ring die is damaged during the operation of the briquetting machine, only the damaged ring die insert 21 needs to be disassembled and replaced, and the entire ring die body 2 does not need to be removed for overall replacement. When disassembling the ring die insert 21, only the worker needs to manually twist the screw sleeve top cover 35 of the fastening assembly 3. Since the screw sleeve helical structure 332 at the lower end of the screw sleeve 33 is embedded with the screw sleeve top cover helical structure 351 at the upper end of the screw sleeve top cover 35, when the screw sleeve top cover 35 is rotated, the screw sleeve 33 will be lifted, the spring 34 above the screw sleeve 33 will be compressed, and the screw sleeve 33 can move upwards in the rectangular guide hole 212 on the lower surface of the ring die insert 21. During the upward movement of the screw sleeve 33, it will not rotate due to the restraint of the rectangular guide hole 212. When the disassembly through hole 352 on the screw sleeve top cover 35 is superimposed with the tail plate 321 on the fastening rod 32, that is, when the tail plate 321 on the fastening rod 32 can pass through the disassembly through hole 352 on the screw sleeve top cover 35, the screw sleeve top cover 35 can be removed from the fastening rod 32. During the removal of the screw sleeve top cover 35 from the fastening rod 32, the tail plate 321 on the fastening rod 32 gradually passes through the disassembly through hole 352 of the screw sleeve top cover 35, until the screw sleeve top cover 35 is completely separated from the fastening rod 32. Then, the fastening assembly 3, except for the screw sleeve top cover 35, can be disassembled from the ring die insert 21 and the ring die lower plate 1, and the ring die insert 21 can be disassembled from the ring die lower plate 1. The entire disassembly process of the ring die insert 21 is convenient and fast, and can realize the quick disassembly and installation of the ring die insert 21.

[0036] As shown in Figure 1 , 2 , 5, each ring die insert 21 is provided with a half hole 213 on both sides, and the half holes 213 on two adjacent ring die inserts 21 can be spliced into a ring die hole 22. The ring die hole 22 is used for the extrusion molding of the material in the briquetting machine.

[0037] In order to further realize the positioning and connection between the ring die insert 21 and the ring die lower plate 1, and ensure the stability during the operation of the briquetting machine, as shown in Figure 4 , a ring positioning groove 12 is formed on the ring die lower plate 1, and as shown in Figure 5 , 6 , a positioning protrusion 214 is arranged below each ring die insert 21 and can be embedded in the ring positioning groove 12. Through the cooperation between the ring positioning groove 12 and the positioning protrusion 214, the ring positioning groove 12 can bear the extrusion force of the ring die insert 21.

[0038] The spring 34 in the embodiment is sleeved on the fastening rod 32, which presses the screw sleeve 33 against the screw sleeve top cover 35, and further presses the screw sleeve top cover 35 against the tail plate 321 of the fastening rod 32. The pressing block machine vibrates greatly during work. If the traditional bolt fastener is used for the fastening assembly, the bolt fastener is prone to loosening under the vibration working condition, thereby increasing the risk of the ring mold insert 21 falling off from the ring mold lower plate 1. The double-screw fitting structure of the screw sleeve 33 and the screw sleeve top cover 35 in the embodiment can ensure that the screw sleeve top cover 35 will not be accidentally rotated under the influence of vibration under the pressure of the spring 34, thereby ensuring the reliability of the fixation between the ring mold insert 21 and the ring mold lower plate 1.

[0039] As shown in Figure 8 , the tail plate 321 in the embodiment is semicircular, and the disassembly through hole 352 is semicircular (shown in Figure 9 ) corresponding to the semicircular tail plate 321. Figure 6 As shown in , the tail plate 321 of the fastening rod 32 is perpendicular to the fastening rod 32 in the embodiment.

[0040] The gap fit is between the screw sleeve 33 and the fastening rod 32 in the embodiment. The gap fit is between the rectangular plate 331 at the upper end of the screw sleeve 33 and the rectangular guide rail hole 212 on the lower surface of the ring mold insert 21. The above gap fit can minimize the friction between the screw sleeve 33 and the fastening rod 32 and between the screw sleeve 33 and the ring mold insert 21.

[0041] In order to facilitate the tail plate 321 of the fastening rod 32 to pass through the disassembly through hole 352 of the screw sleeve top cover 35, the lower limit deviation of the disassembly through hole 352 opened on the screw sleeve top cover 35 is greater than the upper limit deviation of the tail plate 321 of the fastening rod 32.

[0042] In order to facilitate the assembly and disassembly of the fastening assembly 3, the top cover 31 and the fastening rod 32 are detachably fixedly connected through the thread structure in the embodiment.

[0043] The ring die for the easy-to-disassemble briquetting machine of the embodiment only needs to twist the screw sleeve top cover 35 by hand when disassembling the ring die insert 21 from the ring die lower plate 1. Since the screw sleeve helical structure 332 at the lower end of the screw sleeve 33 is embedded with the screw sleeve top cover helical structure 351 at the upper end of the screw sleeve top cover 35, the screw sleeve top cover 35 is lifted when it rotates, the spring 34 above the screw sleeve 33 is compressed, and the screw sleeve 33 can move upward in the rectangular guide rail hole 212 on the lower surface of the ring die insert 21 and cannot rotate during the upward movement under the constraint of the rectangular guide rail hole 212. When the disassembly through hole 352 on the screw sleeve top cover 35 is overlapped with the tail plate 321 on the fastening rod 32, i.e., when the tail plate 321 on the fastening rod 32 can pass through the disassembly through hole 352 on the screw sleeve top cover 35, the screw sleeve top cover 35 can be removed from the fastening rod 32. During the removal of the screw sleeve top cover 35 from the fastening rod 32, the semicircular tail plate 321 on the fastening rod 32 gradually passes through the semicircular disassembly through hole 352 on the screw sleeve top cover 35 until the screw sleeve top cover 35 is completely separated from the fastening rod 32. Then, the other components of the fastening assembly 3 except the screw sleeve top cover 35 can be removed from the ring die insert 21 and the ring die lower plate 1. At this time, the fastening connection between the ring die insert 21 and the ring die lower plate 1 is lost, and the ring die insert 21 can be disassembled from the ring die lower plate 1. The entire disassembly process of the ring die insert 21 is convenient and fast, and the quick disassembly and installation of the ring die insert 21 can be achieved.

[0044] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
