Detailed Implementation

[0025] The present invention will be further described below with reference to the embodiments. The described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative effort are all within the protection scope of the present invention.

[0026] Please see Figures 1-4 As shown, this embodiment discloses a quantitative filling device, specifically a sodium hydroxide crystal quantitative filling device, including a support frame 101, a hopper 102, a screw feeding device, and a quantitative filling device; the hopper 102 is used to be installed on the support frame 101; the screw feeding device is connected to the discharge end of the hopper 102 and is used to convey the material in the hopper 102; the quantitative filling device includes a support plate 103, a sliding frame 104, a pulley block 106, a pull rope 105, and a weighing sensor 107. The support plate 103 is disposed at the discharge end of the screw feeding device, the sliding frame 104 is used to slide on the support plate 103, the pulley block 106 is disposed on the support plate 103, one end of the pull rope 105 is connected to the sliding frame 104, and the other end passes around the pulley block 106 and is connected to the weighing sensor 107 disposed on the support frame 101.

[0027] This utility model mainly includes a support frame 101, a hopper 102, a screw feeding device, and a quantitative filling device. In actual use, the hopper 102 is used to temporarily store sodium hydroxide crystals, and the screw feeding device is connected to and communicates with the hopper 102. The sodium hydroxide crystals in the hopper 102 will directly enter the screw feeding device for conveying, and finally the material conveyed by the screw feeding device is contained in a sealed bag. A weighing sensor 107 is connected to the screw feeding device through a controller. During the sodium hydroxide crystal filling process, as the sodium hydroxide crystals in the sealed bag increase in volume... As gravity increases, the sliding frame 104 is pressed against the support plate 103 and then slides. After sliding downward, the sliding frame 104 pulls the pull rope 105 to stretch the weighing sensor 107. When the tension sensed by the weighing sensor 107 reaches the preset value, it immediately transmits a signal to the controller. The controller controls the screw feeder to stop conveying sodium hydroxide crystals, thereby realizing the quantitative filling of sodium hydroxide crystals. This setting can realize the quantitative filling of sodium hydroxide crystals and prevent waste and loss of sodium hydroxide crystals due to insufficient or excessive filling.

[0028] like Figure 2 As shown, in one optional implementation, the screw feeding device in this embodiment includes a first cylinder 108, a second cylinder 109, a first screw blade 110, a second screw blade 111, a first main shaft 112, and a second main shaft 113. The first cylinder 108 is fixedly connected to the hopper 102 to form an integral structure. The hopper 102 communicates internally with the first cylinder 108. One end of the first main shaft 112 is rotatably connected to the end face of the first cylinder 108, and the other end is rotatably and sealingly connected to the hopper 102. The first screw blade 110 is fixedly mounted on the first main shaft 112. The outlet end of the first cylinder 108 is connected to and communicates with the second cylinder 109. One end of the second cylinder 109 is fixedly connected to the first cylinder 108, and the other end is fixedly connected to the support plate 103. After passing through the support plate 103, it extends to the top of the sliding frame 104. The two ends of the second main shaft 113 are rotatably and sealingly connected to the two ends of the second cylinder 109, respectively. The second spiral blade 111 is fixedly installed on the second main shaft 113. The support frame 101 is provided with a drive structure, which is used to drive the first main shaft 112 and the second main shaft 113 to rotate.

[0029] In actual use, after sodium hydroxide crystals are poured into the hopper 102, they enter the first cylinder 108 from the outlet end of the hopper 102. At the same time, the drive structure drives the first main shaft 112 and the second main shaft 113 to rotate. When the first main shaft 112 and the second main shaft 113 rotate, they drive the first spiral blade 110 and the second spiral blade 111 to feed the sodium hydroxide crystals into the first cylinder 108 and the second cylinder 109 respectively. The sodium hydroxide crystals flow from the first cylinder 108 into the second cylinder 109. Finally, the sodium hydroxide crystals enter the sealed bag from the outlet end of the second cylinder 109 for quantitative filling.

[0030] like Figure 1 as well as Figure 2 As shown, as an optional implementation, in this embodiment, the drive structure includes a first motor 114 and a second motor 115. The end of the first motor 114 is provided with a first drive pulley 116, and the end of the second motor 115 is provided with a second drive pulley 117. A first driven pulley 118 is fixedly provided on the first main shaft 112, and a second driven pulley 119 is fixedly provided on the second main shaft 113. A first belt 120 is sleeved on the first drive pulley 116 and the first driven pulley 118, and a second belt 121 is sleeved on the second drive pulley 117 and the second driven pulley 119.

[0031] In actual use, the first motor 114 rotates, driving the first drive pulley 116 to rotate. Under the friction of the first belt 120, the first driven pulley 118 rotates, which in turn drives the first main shaft 112 to rotate, thus conveying the sodium hydroxide crystals inside the first cylinder 108. The second motor 115 rotates, driving the second drive pulley 117 to rotate. Under the friction of the second belt 121, the second driven pulley 119 rotates, thus driving the second main shaft 113 to rotate. The second main shaft 113 then conveys the sodium hydroxide crystals inside the second cylinder 109.

[0032] like Figure 2 as well as Figure 4 As shown, as an optional implementation, in this embodiment, the pulley block 106 includes a first fixed pulley 122 and a second fixed pulley 123. The first fixed pulley 122 and the second fixed pulley 123 are both fixedly installed on the support plate 103. The first fixed pulley 122 is located above the frame 131, and the second fixed pulley 123 is located below the weighing sensor 107. The pull rope 105 first passes around the first fixed pulley 122 from bottom to top at a position close to the support plate 103, and then from top to bottom, it winds around the second fixed pulley 123 from the side close to the first fixed pulley 122 before connecting to the weighing sensor 107.

[0033] likeFigure 2 As shown, in some embodiments, a stirring assembly is provided inside the hopper 102. The stirring assembly includes a stirring shaft 124 and a plurality of stirring rods 125. The stirring shaft 124 is rotatably and sealedly connected to the hopper 102. The stirring shaft 124 is located above the screw feeder, and the plurality of stirring rods 125 are all mounted on the stirring shaft 124.

[0034] In actual use, the stirring shaft 124 is connected to the first main shaft 112 through a transmission mechanism. When the first main shaft 112 rotates, it drives the stirring shaft 124 to rotate. When the stirring shaft 124 rotates, it drives several stirring rods 125 to rotate synchronously, thereby stirring the sodium hydroxide crystals inside the silo 102 and preventing the sodium hydroxide crystals from clogging the inlet of the first cylinder 108.

[0035] As an optional implementation, in this embodiment, the transmission mechanism is a sprocket transmission mechanism, which includes a driving sprocket 126 fixedly mounted on the first main shaft 112 and a driven sprocket 127 fixedly mounted on the stirring shaft 124. A chain 128 is sleeved on the driving sprocket 126 and the driven sprocket 127. In use, when the first main shaft 112 rotates, the stirring shaft 124 is driven to rotate synchronously through the cooperation of the driving sprocket 126, the chain 128 and the driven sprocket 127.

[0036] In some embodiments, the stirring shaft 124 is rotatably and sealed to the hopper 102 via the bearing seat 129.

[0037] In actual use, the bearing seat 129 is fixedly installed on the outer wall of the hopper 102, and the stirring shaft 124 is rotatably and sealed to the outer wall of the hopper 102 through the bearing seat 129. The advantage of this arrangement is that by setting the bearing seat 129, the connection between the stirring shaft 124 and the hopper 102 can be sealed, and the friction between the stirring shaft 124 and the hopper 102 can be reduced, making the rotation between the stirring shaft 124 and the hopper 102 smoother.

[0038] like Figure 1 As shown, in some embodiments, a support base 130 is provided on the support frame 101, which is used to support the screw feeder.

[0039] In actual use, the support base 130 is fixedly installed on the support frame 101. The first cylinder 108 and the second cylinder 109 are both fixedly installed on the support base 130. The support base 130 can support the first cylinder 108 and the second cylinder 109, ensuring the overall stability of the screw feeder during operation.

[0040] like Figure 1As shown, in some embodiments, the sliding frame 104 includes a frame 131 and a plurality of rollers 132, the plurality of rollers 132 being rotatably mounted on the frame 131, the frame 131 being used to slide on the support plate 103.

[0041] In actual use, the purpose of setting up several rollers 132 is to facilitate the handling of sodium hydroxide crystals after they are filled. The sliding friction that originally occurred between the sealed bag and the frame 131 is transformed into rolling friction between the sealed bag and several rollers 132, making it easier for staff to handle the filled sodium hydroxide crystals.

[0042] In such Figure 3 As shown, in some embodiments, the discharge end of the screw feeder is provided with an anti-clogging component, which is used to prevent the discharge end of the screw feeder from becoming blocked.

[0043] As an optional implementation, in this embodiment, the anti-clogging component includes two vibration motors 133, which are installed at the discharge end of the second cylinder 109. In use, the two vibration motors 133 are started, and the vibration motors 133 vibrate the material inside the second cylinder 109, effectively preventing material from piling up inside the second cylinder 109.

[0044] In some different embodiments, the anti-clogging component includes a hose, a bracket, and a cylinder. The hose is one section of the second cylinder 109 near the discharge end. The bracket is fixedly installed on the second cylinder 109 away from the hose. The fixed end of the cylinder is installed on the bracket, and the movable end is connected to a push block for contacting the outer wall of the hose.

[0045] In actual use, the staff continuously control the cylinder to extend and shorten, so that the pusher blocks continuously squeeze the position of the hose, which can effectively prevent material from piling up inside the second cylinder 109.

[0046] In some embodiments, a waist-shaped groove 134 is provided on the support plate 103, and a sliding rod 135 is provided on the frame 131. The sliding rod 135 is used to slide inside the waist-shaped groove 134. One end of the pull rope 105 is connected to the sliding rod 135, and the other end is wound around the pulley block 106 and connected to the weighing sensor 107.

[0047] In actual use, limiting plates 136 are provided at both ends of the sliding rod 135. The two limiting plates 136 clamp the sliding rod 135 on the waist-shaped groove 134. The diameter of the limiting plates 136 is larger than the size of the waist-shaped groove 134. The purpose is to prevent the sliding rod 135 from disengaging from the waist-shaped groove 134. During use, the sealing bag is placed on several rollers 132, and the inlet of the sealing bag covers the outlet of the second cylinder 109. As sodium hydroxide crystals are continuously filled, the gravity on the frame 131 increases. The frame 131 and the sliding rod 135 slide together inside the waist-shaped groove 134. The pull rope 105 pulls the weighing sensor 107 to monitor the filling of sodium hydroxide crystals, and finally completes the quantitative filling of sodium hydroxide crystals.

[0048] In some embodiments, the hopper 102 is provided with an observation window 137, which is a transparent structure.

[0049] In actual use, the purpose of setting up the transparent observation window 137 is to facilitate the staff to observe the amount of sodium hydroxide crystals inside the silo 102, so as to facilitate the staff to replenish the material.

[0050] In some embodiments, a guide ramp 138 is provided at the bottom of the hopper 102.

[0051] In practical use, the purpose of setting the guide slope 138 is to facilitate the feeding of sodium hydroxide crystals.

[0052] In some embodiments, a dust cover 139 is provided on the support frame 101.

[0053] In actual use, the dust cover 139 is used to cover the first driving pulley 116, the first driven pulley 118, the driving sprocket 126, and the driven sprocket 127. The main function of the dust cover 139 is to protect the first driving pulley 116, the first driven pulley 118, the driving sprocket 126, and the driven sprocket 127 from dust.
