[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0029] See also Figures 1-8As shown, an automatic weighing and feeding type raw material mixing barrel for processing ceramic fiber filter tubes includes a pretreatment box 1, and a processing mechanism is provided inside the pretreatment box 1. The processing mechanism is characterized in that the processing mechanism includes a mounting plate 111, the mounting plate 111 is mounted on the right side wall of the pretreatment box 1, and a rotating rod 112 is rotatably connected to the mounting plate 111. The left end of the rotating rod 112 is fixedly connected to a rotating plate 113, and a rotating block 114 is rotatably connected to the side wall of the rotating plate 113. The right inner wall of the pretreatment box 1 is fixedly connected to the rotating plate 113. There is a fixed block 115, and an inserting plate 116 is inserted into the fixed block 115. The upper and lower ends of the inserting plate 116 are respectively fixedly connected with a stopper 117 and a connecting frame 118. The bottom of the connecting frame 118 is connected to a material guide wave plate 119, and the material guide wave plate 119 is provided with multiple groups of material guide grooves 121. Three groups of mounting frames 122 are installed at the bottom of the material guide wave plate 119, and the bottom of the three groups of mounting frames 122 are each equipped with multiple groups of percussion hammers 123. Multiple groups of screening barrels 124 are rotatably connected between the front and rear inner walls of the pretreatment box 1;

[0030] It should be noted that, first, after the raw material enters the pretreatment box 1 through the feed port 2, it falls on the guide wave plate 119 and starts to guide the raw material through the three sets of guide grooves 121. During this process, the rotating rod 112 rotates, so that the rotating plate 113 drives the rotating block 114 to rotate back and forth, driving the connecting frame 118 to move up and down. At this time, the insert plate 116 slides up and down in the fixed block 115, and the stopper 117 plays a role in limiting. The connecting frame 118 moves back and forth up and down, which can It shakes up and down to avoid accumulation, plays a guiding role and increases the feeding speed. Then, after the raw materials are rotated through multiple groups of screening drums 124 for the first screening, the agglomerated or clumped raw materials will fall into the gap between each two groups of screening drums 124. Since multiple groups of percussion hammers 123 are provided, the guide wave plate 119 can drive multiple groups of percussion hammers 123 to move up and down while reciprocating up and down, and the balls in each gap are knocked apart, thereby avoiding the influence of agglomeration on the weighing accuracy during the subsequent weighing process.

[0031] A sieve plate 125 is rotatably connected to the rear inner wall of the pretreatment box 1, and a rotating shaft 126 is fixedly connected to the front side wall of the sieve plate 125, and the rotating shaft 126 extends outward. The outer surface of the rotating shaft 126 is fixedly connected to a moving block 129, and a connecting ring 127 is fixedly connected to the front side wall of the pretreatment box 1, and a groove 128 matching the moving block 129 is provided in the connecting ring 127. A spring 130 is connected between the lower surface of the moving block 129 and the lower inner wall of the groove 128. A second motor 131 is installed on the front side wall of the pretreatment box 1 through a support frame, and the output end of the second motor 131 passes through the front side wall of the pretreatment box 1 and is fixedly connected to an eccentric wheel 132. The left and right sides of the rear inner wall of the pretreatment box 1 are rotatably connected with stirring shafts 140, and the outer surfaces of the two sets of stirring shafts 140 are installed with crushing blades 141.

[0032] It should be noted that after the raw materials have been screened by multiple groups of screening barrels 124, they fall onto the screen plate 125 for secondary screening. The raw material particles that meet the standards pass through the screen plate 125 directly, and the remaining raw materials are accumulated on the upper surface of the screen plate 125. By starting the second motor 131, the eccentric wheel 132 is driven to rotate back and forth to squeeze the right side of the screen plate 125 upward. At this time, the right side of the screen plate 125 moves upward and tilts, so that the remaining raw materials are further processed by the crushing blades 141 on both sides. In the process of squeezing the right side of the screen plate 125, the rotating shaft 126 rotates, so that 129 rotates in the groove 128. The groove 128 can limit the inclination of the screen plate 125. Since a spring 130 is provided, the spring 130 can be squeezed during the rotation to play a reset role, which can play a secondary processing role for the remaining raw materials and further improve the accuracy of subsequent weighing.

[0033] Furthermore, the pretreatment mechanism also includes a chain 133, which is transmission-connected to the sprocket surface of multiple groups of screening drum 124 shafts, a transmission rod 135 is installed on the right side wall of the pretreatment box 1 through a first clamping block, and a first conveyor belt 134 is transmission-connected between the rear end of the transmission rod 135 and one end of one group of screening drum 124 shafts through two groups of transmission wheels, a driven rod 136 is installed on the right side wall of the pretreatment box 1 through a second clamping block, and the upper and lower ends of the driven rod 136 are fixedly connected to a transmission gear 138, the right end of the rotating rod 112 and the outer surface of the transmission rod 135 are fixedly connected to a driven gear 137, and the two groups of driven gears 137 and the two groups of transmission gears 138 are meshed with each other, and a second conveyor belt 139 is transmission-connected between the outer surface of the output end of the second motor 131 and the front end of the transmission rod 135 through two groups of transmission wheels.

[0034] It should be noted that during use, the second motor 131 is first started, and the transmission rod 135 is driven to start rotating through the second conveyor belt 139. The rotation of the transmission rod 135 drives the rotating rod 112 to rotate through the driven rod 136 and the two sets of transmission gears 138. At the same time, the other end of the transmission rod 135 and one set of the screening drum 124 shaft bodies are transmitted through the first conveyor belt 134, thereby driving multiple sets of screening drums 124 to rotate. In this process, a third conveyor belt is connected between one end of the leftmost screening drum 124 shaft body and one end of one set of stirring shafts 140. Subsequently, the fourth conveyor belt is used between the two sets of stirring shafts 140 to realize that the two sets of stirring shafts 140 drive the two sets of crushing blades 141 to rotate to perform secondary processing of the raw materials. In the above process, the transmission can be driven by one driving source, which saves costs.

[0035] Furthermore, the top of the pretreatment box 1 is connected to a feed port 2, the bottom of the pretreatment box 1 is provided with a discharge port, and a discharge valve is provided at the discharge port, a stirring barrel 6 is provided on the left side of the pretreatment box 1, a fixing ring 5 is fixedly connected to the right side of the circumferential surface of the stirring barrel 6, a conveying pipe 3 is installed in the fixing ring 5, a first motor 4 is installed at the bottom of the conveying pipe 3, and a shaftless auger is installed at the output end of the first motor 4, an adjustment mechanism is provided between the pretreatment box 1 and the conveying pipe 3, and the adjustment mechanism includes a third motor 211, the third motor 211 is installed at the bottom of the fixed ring 5, and the output end of the third motor 211 passes through the fixed ring 5 and is fixedly connected to a bidirectional screw 212, the outer surface of the bidirectional screw 212 is threadedly connected to an adjusting ring 213 and an adjusting frame 214, and two groups of limiting card plates 215 are fixedly connected to the right side of the circumferential surface of the mixing barrel body 6. The left ends of the adjusting ring 213 and the adjusting frame 214 are both slidably connected to the two groups of limiting card plates 215 through card blocks, and the other end of the adjusting frame 214 is fixedly connected to a protective plate 216.

[0036] It should be noted that after the pretreatment of the raw materials is completed, the discharge is controlled by the discharge valve at the bottom of the pretreatment box 1 and transported to the weighing platform 314 for weighing. Before the start of this process, the third motor 211 is started in advance to rotate forward, so that the adjustment ring 213 drives the pretreatment box 1 to move downward, and the adjustment frame 214 drives the protective plate 216 to move upward, thereby reducing the distance between the discharge port and the weighing platform 314. At the same time, the rising protective plate 216 can play a protective role to avoid the influence of factors such as wind direction. By providing two sets of limit clamps 215, the movement of the adjustment ring 213 and the adjustment frame 214 can be limited.

[0037] Furthermore, a material conveying trough 311 is provided on the outer surface of the conveying pipe 3, and a material guide rack 312 is fixedly connected to the right side of the circumferential surface of the conveying pipe 3, an extension rack 313 is connected to the top side wall of the material guide rack 312, and a weighing platform 314 is rotatably connected between the front and rear inner walls of the extension rack 313, and an L-shaped frame 315 is fixedly connected to the right inclined surface of the material guide rack 312, and the bottom of the weighing platform 314 and the extended end of the L-shaped frame 315 are fixedly connected with hinge blocks, and a telescopic cylinder 316 is movably hinged between the two sets of hinge blocks.

[0038] It should be noted that after the raw materials are weighed on the weighing platform 314, the discharge port is closed, the third motor 211 is started to reverse, and after the position between the adjusting ring 213 and the adjusting frame 214 is adjusted, the telescopic cylinder 316 is started to extend, so that the weighing platform 314 rotates clockwise. After rotating to a certain angle, the raw materials enter the feed trough 311 through the extension frame 313, and then the weighed raw materials are transported to the mixing barrel 6 through the shaftless dragon in the conveying pipe 3 for the mixing process.

[0039] Furthermore, each group of hammers 123 is located directly above the two groups of screening barrels 124, a slider 120 is fixedly connected to the left wall of the material guide wave plate 119, and a sliding groove matching the slider 120 is opened on the left inner wall of the pretreatment box 1, and the slider 120 is slidably connected in the sliding groove.

[0040] It should be noted that by arranging each group of striking hammers 123 to be located directly above the two groups of screening barrels 124, misalignment that affects the dispersion effect of the raw materials can be avoided, and the slider 120 is slidably connected in the sliding groove to improve stability during movement.

[0041] Furthermore, a mounting groove is provided on the rear inner wall of the weighing platform 314, and a screw is rotatably connected in the mounting groove, and one end of the screw is installed on the driving motor, and an adjustment block is threadedly connected to the outer surface of the screw, and a scraper 317 is installed at one end of the adjustment block.

[0042] It should be noted that after adjusting the angle of the weighing platform 314, the drive motor can be started to drive the screw to rotate, so that the adjustment block drives the scraper 317 to move, scraping the raw materials into the extension frame 313, thereby improving the feeding efficiency.

[0043] When the present invention is used:

[0044] Step 1: First, after the raw materials enter the pretreatment box 1 through the feed inlet 2, they fall on the guide wave plate 119 and start guiding the raw materials through three groups of guide troughs 121. In this process, the rotating rod 112 rotates, so that the rotating plate 113 drives the rotating block 114 to rotate back and forth, driving the connecting frame 118 to move up and down. At this time, the insert plate 116 slides up and down in the fixed block 115, and the stopper 117 plays a role of limiting. The connecting frame 118 moves up and down, which can shake the raw materials falling on the guide wave plate 119 up and down. Then, after the raw materials pass through multiple groups of screening barrels 124 for the first screening, the agglomerated or agglomerated raw materials will fall into the gap between each two groups of screening barrels 124. Since there are multiple groups of knocking hammers 123, the guide wave plate 119 can drive multiple groups of knocking hammers 123 to move up and down while reciprocating up and down, The balls in each gap are knocked apart, and the raw materials after being screened by multiple groups of screening barrels 124 fall on the screen plate 125 for secondary screening. The raw material particles that meet the standards pass through the screen plate 125 directly, and the remaining raw materials are accumulated on the upper surface of the screen plate 125. By starting the second motor 131, the eccentric wheel 132 is driven to rotate reciprocatingly upward to squeeze the right side of the screen plate 125. At this time, the right side of the screen plate 125 moves upward and tilts, so that the remaining raw materials are further processed by the crushing blades 141 on both sides. In the process of squeezing the right side of the screen plate 125, the rotating shaft 126 rotates, so that 129 rotates in the groove 128. The groove 128 can limit the inclination of the screen plate 125. Since a spring 130 is provided, the spring 130 can be squeezed during the rotation to play a reset role, thereby completing the secondary processing of the remaining raw materials.

[0045] Step 2: After the pretreatment of the raw materials is completed, the discharge is controlled by the discharge valve at the bottom of the pretreatment box 1 and transported to the weighing platform 314 for weighing. Before the start of this process, the third motor 211 is started in advance to rotate forward, so that the adjustment ring 213 drives the pretreatment box 1 to move downward, and the adjustment frame 214 drives the protective plate 216 to move upward, thereby reducing the distance between the discharge port and the weighing platform 314. At the same time, the rise of the protective plate 216 can play a protective role. After the raw materials are weighed on the weighing platform 314, the discharge port is closed, the third motor 211 is started to reverse, and after adjusting the position between the adjustment ring 213 and the adjustment frame 214, the telescopic cylinder 316 is started to extend, so that the weighing platform 314 rotates clockwise. After rotating to a certain angle, the raw materials enter the feed trough 311 through the extension frame 313, and then the weighed raw materials are transported to the mixing barrel 6 through the shaftless dragon in the conveying pipe 3 for mixing.
