An automatic weighing module and system for powdered dye auxiliaries

Abstract

This invention discloses an automatic weighing module and system for powdered dye auxiliaries. On one hand, the material from the discharge port of the guide cylinder of the guiding mechanism is guided forward, preventing some material from randomly falling into the hopper during the feeding process and affecting weighing accuracy. On the other hand, due to the presence of the speed-reducing gear set, the servo motor drives the hopper to rotate only after multiple revolutions. This allows for sufficient settling time in the hopper. During the early stage of screw reversal, the material remaining at the discharge port will continue to fall in as the screw reverses, providing ample settling time for the hopper and effectively ensuring the final powder state, thus improving weighing accuracy. Because of the second and first torsion spring seats in this structure, the turntable clock is at the initial end position before the screw reverses, ensuring sufficient settling time for the hopper. In this structure, the forward and reverse rotations are cyclically performed to accumulate the weighed mass, thereby obtaining the required powder mass for output. The impact force of the falling powder has minimal impact on the weighing progress.

Description

Technical Field

[0001] This invention relates to the field of printing and dyeing chemicals, specifically to an automatic weighing module and system for powdered dye auxiliaries. Background Technology

[0002] Currently, in China's printing and dyeing industry, the key processes affecting the quality of printed and dyed products, particularly in most dyeing or printing processes (boiling, bleaching, mercerizing, weighing and color matching, pigment preparation, etc.), involve material preparation issues. These material preparation processes are largely controlled manually. Data generated throughout the entire production process is primarily analyzed and processed manually. For example, powdered dyes are weighed manually, spoonful by spoonful—a purely manual operation that is tedious and prone to spillage, resulting in waste and environmental pollution.

[0003] Therefore, in traditional proportioning processes, the entire process is completed manually, resulting in low precision, poor accuracy, significant influence from human factors, high labor intensity, and harsh operating environment.

[0004] With the continuous development of new processes and technologies in textile printing and dyeing, textile printing and dyeing equipment is constantly being updated. At present, new equipment for pretreatment, dyeing, printing and finishing is emerging in an endless stream in the printing and dyeing industry. In particular, the adoption of frequency conversion technology and microcomputer technology in electric drives has greatly improved the synchronization performance of the equipment.

[0005] Currently, there are some automatic batching devices on the market, but they also have some shortcomings. For example, most of them use open screw conveyors, which can easily cause dust problems. On the other hand, if multiple materials need to be weighed and mixed, they need to be done in batches, which is relatively inefficient. Also, since traditional weighing methods generally weigh during the conveying process, the weight of the materials is often inaccurate due to the impact of gravity. Summary of the Invention

[0006] The purpose of this invention is to overcome the above-mentioned shortcomings in the prior art and to provide an automatic weighing module and system for powdered dye auxiliaries with a closed conveying system that effectively alleviates the impact of gravity on weighing accuracy.

The drive module includes a first ratchet group, a second ratchet group, a speed-reducing gear group, and an intermittent rotation module. The end of the guide screw is fixed to the ratchet of the first ratchet group. The ratchet teeth of the ratchet are set on the outer wheel disk. The connecting shaft of the outer gear is fixed to the shaft at the beginning of the speed-reducing gear group. The ratchet of the second ratchet group is fixed to the shaft at the end of the speed-reducing gear group. The outer gear disk of the second ratchet group meshes with the drive gear of the intermittent rotation module. The drive gear is fixed to the turntable, and the turntable is equipped with a lever. The lever is adapted to the grooved wheel of the intermittent rotation module, driving the grooved wheel to rotate. The grooved wheel is fixed to the rotation shaft of the fixed frame, causing the fixed frame to rotate. The rotation shaft of the turntable is connected to a second torsion spring seat, so that the lever is always at the end point of the drive grooved wheel.

[0008] Preferably, the angle at which the lever drives the grooved wheel to rotate is 100-120°.

[0009] Preferably, the speed-reducing gear set includes: a worm gear mechanism, a first helical gear, a second helical gear, and several transmission gear sets. The worm of the worm gear mechanism is fixed to the outer wheel of the first ratchet set. The connecting shaft of the worm of the worm gear is fixed with the first helical gear. The first helical gear meshes with the second helical gear. The connecting shaft of the second helical gear meshes with several transmission gear sets in sequence. The shaft of the last gear in the several transmission gear sets is fixed to the ratchet of the second ratchet set.

[0010] Preferably, the material guiding mechanism has a partition plate rotatably installed on the side end of the material guiding cylinder at the discharge port.

[0011] An automatic weighing system for powdered dye auxiliaries includes several discharge modules and several storage modules concentrically arranged on a collection pipeline to form a multi-material module. The discharge trough is connected to the collection pipeline, and the collection pipeline of the multi-material module is stacked vertically through pipeline connectors to form a multi-layer material module.

[0012] Preferably, the discharge trough is inclined, and an inclined baffle is provided on the pipe wall of the collection pipeline at the upper end of the discharge trough.

[0013] Preferably, the storage module is arranged and fixed on a lifting bracket. The lifting bracket includes a bracket body and a lifting platform mechanism. The lifting platform moves longitudinally on the bracket body through the lifting mechanism to lift materials to the storage module position for feeding and maintenance.

[0014] Preferably, the lifting platform is equipped with an automatic feeding mechanism, which includes a transverse conveyor shaft seat, a fixed platform, a bucket clamp, and a flipping mechanism. The base of the conveyor shaft seat is fixed to the bottom of the lifting platform. The sliding seat of the transverse conveyor shaft seat is fixed to the fixed platform for pushing the fixed platform to match the feeding port. The feeding port is U-shaped. The fixed platform and the longitudinal plate form an L-shape. The fixed platform and the longitudinal plate match the feeding port to form a sealed space. The longitudinal plate is equipped with a bucket clamp through the flipping mechanism. A valve body is provided at the bottom of the feeding port.

[0017] Compared with existing technologies, this invention has the following advantages and effects: On the one hand, this invention guides the material from the discharge port of the guide cylinder of the material guiding mechanism forward, avoiding the random falling of some material into the hopper during the feeding process, which affects the weighing accuracy. On the other hand, due to the presence of the speed reduction gear set, the servo motor drives the hopper to rotate only after multiple revolutions, giving the hopper sufficient settling time. Furthermore, in the early stage of screw reversal, the material retained at the discharge port will continue to fall in as the screw reverses, providing the hopper with sufficient settling time and effectively ensuring the final powder state. To improve weighing accuracy, the second torsion spring seat in this structure ensures that the turntable clock is at its initial end position before the screw reverses, for example, in the previous section. When rotation stops, the second torsion spring seat resets (its torsional force is greater than that of the first torsion spring seat), causing the turntable lever to reset. Simultaneously, the hopper can be flipped a second time to further clean up the powder falling into the hopper. This ensures sufficient settling time. In this structure, forward and reverse rotations are performed cyclically to accumulate weighed mass, thereby obtaining the required powder mass for output. The impact force of the falling powder has minimal impact on the weighing progress. Attached Figure Description

Detailed Implementation

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0030] See Figures 1-10This embodiment relates to an automatic weighing module 106 for powdered dye auxiliaries, including a storage module 101. The storage module 101 is equipped with a guiding mechanism for guiding the material to the weighing module 106. The guiding mechanism includes a guiding screw 102 connected to a drive motor. An outlet 104 is provided at the end of the guiding mechanism. A unit weighing module 106 is provided at the outlet 104. The unit weighing module 106 includes a material... The unit includes a hopper 105, a weighing module 106, a fixing frame 107, and a drive module. The weighing module 106 is disposed within the discharge trough 108. The hopper 105 is positioned directly below the discharge port 104. The hopper 105 is mounted on the weighing module 106 and connected to the fixing frame 107. The fixing frame 107 is rotatably mounted on the wall of the discharge trough 108 via a first torsion spring seat 109, ensuring that the initial position of the fixing frame 107 always faces upwards. The drive module... The module includes a first ratchet assembly 110, a second ratchet assembly, a speed-reducing gear assembly 112, and an intermittent rotation module 113. The end of the guide screw 102 is fixed to the ratchet of the first ratchet assembly 110. The ratchet teeth of the ratchet are set on the outer gear disk. The outer gear connecting shaft is fixed to the shaft at the beginning of the speed-reducing gear assembly 112. The ratchet of the second ratchet assembly is fixed to the shaft at the end of the speed-reducing gear assembly 112. The outer gear disk of the second ratchet assembly is connected to the drive shaft of the intermittent rotation module 113. The drive gear 114 is engaged with the turntable 115, which is fixed to the turntable 115. The turntable 115 is provided with a lever 116, which is adapted to the grooved wheel 117 of the intermittent rotation module 113, driving the grooved wheel 117 to rotate. The grooved wheel 117 is fixed to the rotation shaft of the fixed frame 107, causing the fixed frame 107 to rotate. The rotation shaft of the turntable 115 is connected to a second torsion spring seat, so that the lever 116 is always at the end point of the drive grooved wheel 117.

[0031] The working method based on the above structure is as follows: During the material conveying stage, the guide screw 102 of the material guiding mechanism rotates forward to convey the powder to the hopper 105. Since the end of the guide screw 102 is connected to the first ratchet set 110, the forward rotation of the ratchet in the first ratchet set 110 does not drive the external gear disk to rotate. A position sensor is set on the upper side of the hopper 105. When the material is conveyed to the appropriate position, the servo motor stops rotating forward and reverses. At this time, the end of the guide screw 102 drives the ratchet in the first ratchet set 110 to rotate, which synchronously drives its external gear disk to rotate. The external gear disk is connected to the speed reduction gear set 112 (the speed reduction gear set 112 reduces speed through the gear set transmission ratio. For example, when the external gear disk rotates one revolution, the end gear of the speed reduction gear set 112 rotates 1 / 10 revolution). Specifically, for example, the speed-reducing gear set 112 includes: a worm gear mechanism 119, a first helical gear 120, a second helical gear 121, and several transmission gear sets. The worm of the worm gear mechanism 119 is fixed to the outer disk of the first ratchet set 110. The connecting shaft of the worm gear's worm is fixed to the first helical gear 120. The first helical gear 120 meshes with the second helical gear 121. The connecting shaft of the second helical gear 121 meshes with several transmission gear sets (one or more sets) in sequence. The shaft of the last gear in the several transmission gear sets is fixed to the ratchet of the second ratchet set. At this time, the speed-reducing gear set 112 rotates, driving the second ratchet set to rotate. The outer gear disk of the second ratchet is connected to the transmission teeth and the drive of the turntable 115. The drive gear 114 meshes, causing the drive turntable 115 to rotate. The rotation of the turntable 115 causes the undulating wheel groove to rotate, resulting in the rotation of the fixing frame 107 connecting the wheel groove. This allows the powder to fall into the discharge chute 108 for output. When the lever 116 disengages from the wheel groove, it resets under the action of the first torsion spring seat 109. After the servo motor stops driving, the turntable 115 resets in the reverse direction under the action of the second torsion spring seat. Due to the presence of the second ratchet set, the reset power is not transmitted to the speed reduction gear set 112, thus avoiding reset resistance. In this structure, the guide screw 102 rotates forward to output material, and rotates in reverse to discharge material. Weighing can be performed before discharge. Due to the small height difference, the impact of gravity on weighing accuracy is effectively reduced. The servo motor reverses... The rotation serves two purposes: firstly, it guides the material from the discharge port 104 of the guide cylinder 103 of the guiding mechanism forward, preventing some material from randomly falling into the hopper 105 during the feeding process and affecting weighing accuracy; secondly, due to the presence of the speed reduction gear set 112, the servo motor drives the hopper 105 to rotate only after multiple revolutions, giving the hopper 105 sufficient settling time. During the initial stage of screw reversal, any material remaining at the discharge port 104 will continue to fall in as the screw reverses, allowing the hopper 105 sufficient settling time to effectively ensure the final powder state and improve weighing accuracy. Furthermore, the second torsion spring seat in this structure ensures that the turntable 115 is at its initial end position before the screw reverses, for example, stopping rotation in the previous stage.The second torsion spring seat resets (its torsional force is greater than that of the first torsion spring seat 109), causing the lever 116 of the turntable 115 to reset. Simultaneously, the hopper 105 can be rotated a second time to further clear the powder falling from the hopper. In this structure, the forward and reverse rotations are cyclically performed to accumulate the weighed mass, thereby obtaining the required powder mass for output. The impact force of the falling powder has a relatively small impact on the weighing progress.

[0032] In this embodiment, the lever 116 drives the grooved wheel 117 to rotate at an angle of 100-120°, which allows the material to fall into the discharge trough 108 better during the tumbling process. The guide cylinder 103 of the guide mechanism is rotatably equipped with an isolation plate 122 at the side end of the discharge port 104 to prevent the powder from being guided to the rear end of the cylinder and to increase the amount of powder retained.

[0033] Based on the above structure, this embodiment provides a closed-loop automatic weighing system for powdered dye auxiliaries that enables simultaneous output of multiple materials and proportional mixing. Specifically, it includes several discharge modules and several storage modules 101 concentrically arranged on a converging pipeline 123 to form a multi-material module. The discharge trough 108 is connected to the converging pipeline 123. The converging pipeline 123 of the multi-material module is stacked vertically through pipeline connectors to form a multi-layer material module. This structure adopts a modular structure, which can be selected according to the required scale of material proportioning. At the same time, the stacked structure occupies relatively less planar space, which is conducive to intensive production. In this embodiment, the discharge trough 108 adopts an inclined surface 124. An inclined baffle 125 is provided on the pipe wall of the converging pipeline 123 at the upper end of the discharge trough 108, as shown in the figure. The inclined surface 124 is in the shape of an inverted frustum, which effectively isolates the upper material from being retained at the lower discharge trough 108 opening and effectively corrects the material drop path of the upper layer.

[0034] In this embodiment, a connecting hopper 137 is provided at the bottom of the collection pipe. The connecting hopper 137 is connected to a bellows 138 through a valve body. The head end of the bellows 138 is connected to a cover 139, which is adapted to connect to the receiving bucket for receiving the proportioned output material. Both the connecting hopper 137 and the bellows 138 are made of transparent material, which makes it easy to control whether the proportioned powder is fully received and output.

[0035] In this embodiment, in order to facilitate material loading and maintenance, the storage module 101 is arranged with a lifting bracket fixed on it. The lifting bracket includes a bracket body 126 and a lifting mechanism 127. The lifting platform 128 moves longitudinally on the bracket body 126 through the lifting mechanism 127 to lift the material to the storage module 101 for feeding and maintenance.

[0036] To further automate dust-free material feeding, an automatic feeding mechanism is provided on the lifting platform 128. This mechanism includes a transverse conveyor shaft seat 129, a fixed platform 130, a bucket clamp 131, and a tilting mechanism 132. The transverse conveyor shaft seat 129 (e.g., a linear slide cylinder) is fixed to the bottom of the lifting platform 128. The sliding seat of the transverse conveyor shaft seat 129 is fixed to the fixed platform 130 for pushing the fixed platform 130 to fit with the feeding port 133. The feeding port 133 is U-shaped. The fixed platform 130 and the longitudinal plate 135 form an L-shape, and the fixed platform 130, the longitudinal plate 135, and the feeding port 133 form a sealed space. The longitudinal plate 135 is equipped with a bucket clamp 131 via the tilting mechanism 132 (e.g., a 180° rotating cylinder). 31 (As shown in the figure, due to the left and right clamps that fit the powder hopper, either the left or right clamp is connected to a cylinder for telescopic clamping). The bottom of the feeding port 133 is equipped with a valve body, which closes the port when no material is being added. In order to further improve the feeding and prevent material jamming, a guide vane 136 is also provided at the bottom of the feeding port 133. As shown in the figure, the guide vane 136 rotates to drive the material into the storage module 101. This structure does not require manual feeding. Automated feeding can be achieved by logically controlling each electric component. At the same time, a closed feeding method is used during the feeding process to reduce powder flying during the feeding process and improve the environment in the workshop. In this system, multiple modules can operate synchronously, so that the powder has a certain mixing environment during the batching and output process, reducing the mixing time of subsequent processes and improving efficiency.

[0037] The above description is merely illustrative of the invention. Those skilled in the art can make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined by the claims, all of which should fall within the protection scope of this invention.
