[0064] like Figure 1 and Figure 2 As shown, according to an embodiment of the present application, a propellant roll-forming machine is proposed, comprising: a machine platform 10, a first feeding mechanism 11, a feeding chute 12, a rolling mechanism 13 and a second feeding mechanism 14; the first feeding mechanism 11 is arranged on the machine platform 10, and the first feeding mechanism 11 is used to convey gunpowder; the feeding chute 12 is arranged on the machine platform 10, and the feeding chute 12 is located below the first feeding mechanism 11; the rolling mechanism 13 is arranged on the machine platform 10, and the rolling mechanism 13 is located below the feeding chute 12, and the rolling mechanism 13 is used to roll the gunpowder discharged from the feeding chute 12; the second feeding mechanism 14 is arranged on the machine platform 10, and the second feeding mechanism 14 is located above the feeding chute 12, and the second feeding mechanism 14 is used to convey the rolled gunpowder into the feeding chute 12.

[0065] The propellant roll-forming machine provided in the embodiment of the present application includes a machine table 10, a first feeding mechanism 11, a feeding trough 12, a rolling mechanism 13 and a second feeding mechanism 14. The first feeding mechanism 11 conveys the gunpowder raw material into the feeding trough, and the gunpowder leaks out from the bottom of the feeding trough 12 and enters the rolling mechanism 13, and the gunpowder is rolled once by the rolling mechanism 13; the gunpowder after the first rolling is placed on the second feeding mechanism 14, so that the product after the first rolling is conveyed to the feeding trough 12 by the second feeding mechanism 14, and then the rolling mechanism 13 rolls to complete the secondary rolling of the gunpowder, and the cycle is repeated. The rolled gunpowder is put back on the second feeding mechanism 14, and then conveyed to the rolling mechanism 13 for rolling, so that the finished gunpowder after multiple rolling is obtained. Multiple rolling of the medicine can be achieved according to production needs without transportation, thereby realizing continuous production of multiple rolling forming of gunpowder by one device, improving the production efficiency of the propellant, and increasing the output of the propellant.

[0066] Furthermore, a plurality of storage barrels 15 are provided on the belt of the first feeding mechanism 11 . The storage barrels 15 are used to place gunpowder raw materials. The storage barrels 15 are arranged at equal intervals on the belt of the first feeding mechanism 11 , which helps to achieve periodic and uniform feeding of the first feeding mechanism 11 .

[0067] As a preferred solution, the rolling mechanism 13 includes two pressing rollers, and the two pressing rollers are powered by independent circuits respectively so that the two pressing rollers do not interfere with each other, which is beneficial to improving the safety of the rolling step.

[0068] As a preferred solution, an operation screen 16 is provided on the machine 10, and the operation screen 16 is electrically connected to the control system. The operation screen 16 is used to set various parameters, such as roller speed, roller temperature, feeding speed and other parameters.

[0069] like Figure 1 and Figure 2 As shown, in a feasible embodiment, the propellant roll-forming machine also includes: a fixed frame 17, a locking block 18, a guide seat 19, a push plate 20 and a linear telescopic device 21; the fixed frame 17 is arranged on the machine platform 10; the locking block 18 is arranged on the fixed frame 17; a slide rail is arranged on the guide seat 19, and the guide seat 19 is connected to the locking block 18; the push plate 20 is slidably connected to the slide rail; the linear telescopic device 21 includes a fixed end and a telescopic end, the fixed end of the linear telescopic device 21 is connected to the guide seat 19, and the telescopic end of the linear telescopic device 21 is connected to the push plate 20, and the linear telescopic device 21 is used to drive the push plate 20 to move so as to adjust the coverage area of ​​the push plate 20 on the feed port of the feed chute 12.

[0070] In this technical solution, the guide seat 19 is fixed to the fixed frame 17 by the locking block 18 to fix the guide seat 19 on the machine table 10, and the push plate 20 is driven to move by the linear telescopic device 21; when the gunpowder is fed in sufficient amount, the telescopic end of the linear telescopic device 21 is controlled to extend, and the push plate 20 gradually approaches the feed trough 12 and timely blocks the feed trough 12 to ensure that the feed trough 12 is discharged in a more appropriate amount, and prevent the feed trough 12 from discharging too much, thereby avoiding the occurrence of safety accidents caused by excessive gunpowder accumulation at the rolling mechanism 13; in addition, by controlling the length of the extension of the telescopic end of the linear telescopic device 21, the area of ​​the feed trough 12 covered by the push plate 20 can be adjusted, and then the opening size of the feed port of the feed trough 12 can be adjusted, and the feeding speed can be further controlled to prevent the feed from continuing when the feed trough 12 is blocked, so as to ensure the smoothness and continuity of the feed trough 12, which is conducive to improving the continuity of the gunpowder roller forming production, thereby improving the production efficiency of the propellant and increasing the output of the propellant.

[0071] like Figure 1 and Figure 2As shown, in a feasible embodiment, the propellant roll-forming machine also includes: a scramble frame 22; the scramble frame 22 is arranged on the machine platform 10, and the scramble frame 22 is located above the feed chute 12; the push plate 20 is arranged obliquely to the axis of the feed chute 12, and after the telescopic end of the linear telescopic device 21 is extended, the push plate 20 can extend into the feed chute 12 from one side of the scramble frame 22.

[0072] In this technical solution, a scrambler 22 is provided above the feed chute 12 to scatter the gunpowder during feeding, prevent the gunpowder from sticking, improve the dispersion of the gunpowder, prevent the feed chute 12 from being blocked, and ensure that the feed chute 12 is unobstructed, which is beneficial to improving the uniformity and continuity of the feeding of the feed chute 12 to the rolling mechanism 13, making the density of the gunpowder product after rolling more uniform, and improving the product quality; the push plate 20 is set at an angle to the axis of the feed chute 12, so that the push plate 20 is slightly inclined in the vertical direction. When the telescopic end of the linear telescopic device 21 is extended, the push plate 20 can block the feed channel while being able to extend into the feed chute 12, so that the blocked feed can be automatically cleared by the push plate 20, further reducing the risk of blockage of the feed chute 12, greatly ensuring the continuity of the roller forming production, and improving the production efficiency of the propellant.

[0073] In some examples, the cross bar of the fixed frame 17 is slidably connected to the guide frame through a locking block 18, so that the guide frame, the linear telescopic device 21 and the push plate 20 can slide horizontally relative to the discharge chute 12, so as to adjust the relative position of the push plate 20 and the discharge chute 12 in the horizontal direction, thereby improving the flexibility of the horizontal movement of the push plate 20, so that the push plate 20 can be quickly moved to the position that needs to be blocked or unblocked, and the operation is simple and efficient.

[0074] Furthermore, the debonding frame 22 includes two beams with parallel pressure rollers, and there is a spacing between the two beams. A feed guide mechanism 23 is provided at one end of the second feeding mechanism 14 close to the discharge trough 12. The feed guide mechanism 23 is abutted against a beam close to the second feeding structure to ensure that the gunpowder can be smoothly fed into the discharge trough 12 through the feed guide mechanism 23.

[0076] In this technical solution, a feeding mechanism 24 is arranged below the rolling mechanism 13, and two scraper frames 25 are arranged on the frame of the feeding mechanism 24 near one end of the rolling mechanism 13, and a scraper brush 26 is arranged on the scraper frame 25, and the two scraper brushes 26 are respectively fitted with the sides of the two pressure rollers to prevent the gunpowder produced by the extrusion of the rolling mechanism 13 from adhering to the pressure rollers, ensuring that the gunpowder after rolling falls smoothly on the belt of the feeding mechanism 24, and the gunpowder after rolling by the rolling mechanism 13 is transported by the feeding mechanism 24, so that the gunpowder after rolling has sufficient cooling time when being transported on the feeding mechanism 24, and gradually cools to room temperature as the feeding of the feeding mechanism 24, so that the gunpowder can be cooled in time after each rolling, preventing the gunpowder from being too hot before the next rolling, thereby improving the safety of the gunpowder in the process of multiple rolling forming; the feeding guide mechanism 27 is arranged to be tilted downward to facilitate the transportation of the gunpowder after the last rolling to the next process.

[0077] It can be understood that when the gunpowder on the feeding mechanism 24 needs to be rolled for the next time, after the gunpowder is cooled on the feeding mechanism 24, the staff can directly place the gunpowder on the second feeding mechanism 14, and then the second feeding mechanism 14 will transport it to the discharge chute 12 to wait for the next rolling; when the gunpowder on the feeding mechanism 24 no longer needs to be rolled, the formed gunpowder is guided by the feeding guide mechanism 27 and transported to the next process.

[0078] like Figures 1 to 4 As shown, in a feasible embodiment, the propellant roll-forming machine also includes: a moving mechanism 28 and a cutting mechanism 29; the moving mechanism 28 is arranged on the machine platform 10, and the moving mechanism 28 is arranged at one end of the feeding guide mechanism 27 away from the feeding mechanism 24; the cutting mechanism 29 includes a cutter assembly 291, and the cutter assembly 291 is arranged in a criss-cross shape on the moving mechanism 28.

The first feeding mechanism 11 is arranged above the lower trough 12 along the width direction of the machine 10, and the second feeding mechanism 14 is arranged above the rolling mechanism 13 along the length direction of the machine 10 to prevent the first feeding mechanism 11 and the second feeding mechanism 14 from interfering with each other when feeding, thereby ensuring the smoothness of feeding to the lower trough 12; the feeding mechanism 24 is arranged below the rolling mechanism 13 along the length direction of the machine 10, so as to convey the medicine to the cutting mechanism 29 through the feeding mechanism 24, so that the cutting mechanism 29 can cut the medicine after it is formed, and then the moving mechanism 28 drives the cutting mechanism 29 and the cut medicine to move to the specified position and / or height, so as to realize the collection function of the cut medicine, and integrate the rolling, cutting and collection equipment of the medicine in the same device, so that the rolling, cutting and collection of the medicine can be carried out continuously and efficiently.

[0081] like Figure 3 and Figure 4 As shown, in a feasible embodiment, the moving mechanism 28 includes: a lifting linear guide rail 281, a lifting platform 282 and a lifting chain 283; the lifting linear guide rail 281 is vertically arranged on the machine platform 10; the lifting platform 282 is horizontally arranged, and the lifting platform 282 is connected to the slider of the lifting linear guide rail 281; the first end of the lifting chain 283 is connected to the lifting linear guide rail 281, and the second end of the lifting chain 283 is connected to the lifting platform 282.

[0082] In this technical solution, the lifting platform 282 is arranged on the slider of the lifting linear guide 281, so that the lifting platform 282 can be driven to move flexibly in the vertical direction through the slider of the lifting linear guide 281, and the lifting platform 282 can be driven to rise and fall, thereby realizing the lifting function of the moving mechanism 28, thereby adjusting the height of the cutting mechanism 29 to adapt to the different heights and usage conditions of different staff members; by connecting the two ends of the lifting chain 283 to the top of the lifting platform 282 and the lifting linear guide 281 respectively, damping is provided during the vertical movement of the lifting platform 282 to prevent the lifting platform 282 from rising and falling too fast, thereby improving the stability of the cutting mechanism 29 during lifting and falling.

[0083] like Figure 3 and Figure 4As shown, in a feasible embodiment, the moving mechanism 28 also includes: a translation linear guide 284, a moving seat 285 and a moving chain 286; the translation linear guide 284 is horizontally arranged, and the translation linear guide 284 is connected to the lifting platform 282; the moving seat 285 is connected to the slider of the translation linear guide 284, and the cutting mechanism 29 is arranged on the moving seat 285; the first end of the moving chain 286 is connected to the lifting platform 282, and the second end of the moving chain 286 is connected to the moving seat 285.

[0084] In this technical solution, the moving seat 285 is arranged on the slider of the translation linear guide 284, so that the moving seat 285 can be driven to move flexibly in the horizontal direction through the slider of the translation linear guide 284, thereby realizing the function of the moving mechanism 28 to move in the horizontal direction, thereby adjusting the position of the cutting mechanism 29, so that the height and position of the cutting mechanism 29 can be adjusted through the moving mechanism 28, so as to adapt to the usage of different staff members and make the equipment more practical when used; by connecting the two ends of the moving chain 286 to the lifting platform 282 and the moving seat 285 respectively, damping is provided during the horizontal movement of the moving seat 285 to prevent the moving seat 285 from moving horizontally too fast, thereby improving the stability of the cutting mechanism 29 during horizontal movement.

[0085] like Figure 5 As shown, in a feasible embodiment, the cutting mechanism 29 also includes: a rotating support device 292 and a conveying assembly 293; the rotating support device 292 includes a fixed end and a movable end, and the fixed end of the rotating support device 292 is arranged on the moving mechanism 28; the conveying assembly 293 is connected to the movable end of the rotating support device 292, and the cutter assembly 291 is arranged on the conveying assembly 293, and the conveying assembly 293 is used to convey the gunpowder cut by the cutter assembly 291.

[0086] In this technical solution, the cutter assembly 291 is arranged above the belt of the conveying assembly 293. When the cutter assembly 291 cuts the gunpowder, the gunpowder falls on the belt of the conveying assembly 293 and is conveyed to the equipment of the next process by the conveying assembly 293; the fixed end of the slewing support device 292 is arranged on the movable seat 285, and the conveying assembly 293 is arranged on the movable end of the slewing support device 292, so that the conveying assembly 293 is driven to rotate by the rotation of the movable end of the slewing support device 292, and then after the cutter assembly 291 cuts the formed gunpowder, the conveying direction of the cut gunpowder is changed, and the gunpowder residue generated by the cutting is conveyed to different directions according to size, so as to automatically collect the cut gunpowder according to the shape and size of the gunpowder residue, thereby improving the collection efficiency of the gunpowder residue.

[0087] Specifically, the slewing support device 292 is a slewing rotating cylinder.

[0088] like Figure 4 As shown, in a feasible embodiment, the conveying assembly 293 includes: a first conveying device 2931 and a second conveying device 2932; the first conveying device 2931 is connected to the movable end of the rotary support device 292, and the cutter assembly 291 is arranged on the first conveying device 2931; the frame of the second conveying device 2932 is connected to the frame of the first conveying device 2931, and the second conveying device 2932 is arranged perpendicular to the first conveying device 2931; wherein, the upper belt of the second belt is located below the upper belt of the first belt, and there is a gap between the upper belt of the second belt and the upper belt of the first belt.

[0089] In this technical solution, the first conveying device 2931 is fixed to the movable end of the rotary support device 292, and the frame of the second conveying device 2932 is fixedly connected to the frame of the first conveying device 2931, so that the second conveying device 2932 can rotate synchronously with the first conveying device 2931; the first conveying device 2931 and the second conveying device 2932 are arranged vertically, and the belt of the first conveying device 2931 and the belt of the second conveying device 2932 are staggered, and the first belt and the second belt do not interfere with each other, so that the first conveying device 2931 and the second conveying device 2932 can transport the residual material simultaneously and independently, that is, the first conveying device 2931 and the second conveying device 2932 simultaneously convey the residual material, which further improves the collection efficiency of the gunpowder residual material.

[0090] It is understandable that if Figure 6 , the second conveyor 2932 passes through the inside of the first conveyor 2931, and the second conveyor 2932 and the first conveyor 2931 are arranged in a tic-tac-toe shape. The conveying assembly 293 is composed of the upper layer of the first belt 293a, the upper layer of the second belt 293b, the lower layer of the second belt 293b and the lower layer of the first belt 293a from top to bottom, that is, the upper layer of the second belt 293b is located below the upper layer of the first belt 293a, and there is a gap between the upper layer of the second belt 293b and the upper layer of the first belt 293a to ensure that the first belt 293a and the second belt 293b do not interfere with each other during transmission. Figure 4 and Figure 5 The support of the conveying component 293 is in a tic-tac-toe shape, and the second conveying device 2932 and the first conveying device 2931 share the tic-tac-toe shaped support.

[0091] like Figure 4As shown, in a feasible embodiment, the cutter includes two first cutters 2911 and two second cutters 2912, the first cutters 2911 are arranged parallel to the first conveying device 2931, and the second cutters 2912 are arranged parallel to the second conveying device 2932, and the two first cutters 2911 and the two second cutters 2912 are arranged to form a finished product cavity 32 and four residual material cavities 33; wherein, two opposite residual material cavities 33 are located above the first belt, and the other two opposite residual material cavities 33 are located above the second belt.

[0092] In this technical solution, two first cutters 2911 and two second cutters 2912 are arranged to form a finished product cavity 32 and four residual material cavities 33. The finished product of the shaped gunpowder after cutting is formed in the finished product cavity 32 and taken out by the staff. The edge portion of the shaped gunpowder is formed in the four residual material cavities 33, and the edge portion falls on the first conveying device 2931 and / or the second conveying device 2932. The first conveying device 2931 and / or the second conveying device 2932 are rotated to adjust the transportation direction, and the residual gunpowder is collected uniformly.

[0093] It can be understood that after the gunpowder is cut, the staff only needs to take out the finished gunpowder, and the remaining gunpowder is transported by the first conveying device 2931 and / or the second conveying device 2932. Compared with the existing equipment that needs to take out both the finished gunpowder and the remaining gunpowder, the propellant roller forming machine improves the production efficiency of the propellant and reduces the labor intensity.

[0094] Furthermore, the width between the two first cutters 2911 is equal to the width of the first conveyor 2931, and the width between the two second cutters 2912 is equal to the width of the second conveyor 2932, that is, the width of the residual material chamber 33 is equal to the width of the conveyor, so as to ensure that the edge portion of each piece of gunpowder only falls on the first conveyor 2931 or the second conveyor 2932, that is, to ensure that each piece of residual material can only fall on the belt of one of the conveyor devices and cannot fall on both conveyor devices at the same time, thereby preventing the strip-shaped residual material from falling during the conveying process due to separation from one of the conveyor devices and being unable to be stably supported, that is, avoiding the situation where the residual material falls during transportation due to falling on two conveyor devices at the same time, thereby ensuring the efficiency of gunpowder collection and eliminating the safety hazards caused by the falling of gunpowder residual material during transportation.

[0095] Furthermore, the unloading end of the first conveying device 2931 is provided with a first guide mechanism 30 tilted downward, and the unloading end of the second conveying device 2932 is provided with a second guide mechanism 31 tilted downward, so as to accurately and stably transport the gunpowder residue to the next process. Figure 6The second conveying device 2932 passes through the inside of the first conveying device 2931, and the upper layer of the second belt 293b is located below the upper layer of the first belt 293a and there is a gap. The gap prevents the first belt 293a from contacting the second belt 293b. The height of the gap is very small and due to the obstruction of the first cutter 2911, the residual gunpowder on the second conveying device 2932 can be prevented from entering the gap between the upper layer of the first belt 293a and the upper layer of the second belt 293b, and then the conveying assembly 293 is driven to rotate through the slewing support device 292, so that the gunpowder can rotate with the conveying assembly 293. During the rotation, the edge portion of the gunpowder cut by the cutter assembly 291 can also be collected, thereby improving the collection efficiency of the edge portion of the gunpowder.
