Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of carboxymethyl cellulose production line, and particularly relates to an intelligent suspension conveying system for a carboxymethyl cellulose production line. BACKGROUND

[0002] Carboxymethyl cellulose is a cellulose derivative obtained by chemical modification of natural cellulose. Its preparation process is generally to alkali treatment of cellulose under alkaline conditions, and then react with etherifying agent such as chloroacetic acid to introduce carboxymethyl group, thereby forming a water-soluble polymer compound. Carboxymethyl cellulose is usually white or slightly yellow powder, odorless, tasteless, easily soluble in water and forms a colloid solution with certain viscosity, and has thickening, adhesion, emulsification, suspension, stability and other properties. Based on these properties, it is widely used in food industry, pharmaceutical field, daily chemical industry, and textile, papermaking, oil drilling and other industrial fields, and is an important water-soluble polymer material.

[0003] The production of carboxymethyl cellulose needs to go through a series of continuous processes, mainly including raw material online, raw material crushing, alkalization reaction, etherification reaction, neutralization, ethanol washing, centrifugal separation, drying, crushing and screening, finished product packaging and finished product storage. In the above production process, after the carboxymethyl cellulose is completed, the finished product is usually transported to each warehouse for stacking and storage by a forklift. However, the current finished product storage and transportation method has many problems: on the one hand, due to the large number of warehouses and the long distance between each warehouse and the finished product packaging station, the finished product of each plate needs to be transported by a forklift from the outlet of the finished product packaging station to the corresponding warehouse, which makes the intelligent degree of the whole transportation process very low and completely relies on manual operation of the forklift, not only greatly increases the labor intensity of workers, but also easily causes collision, falling and other safety risks during long-distance forklift transportation due to road conditions, operation and other factors, which poses a threat to the safety of the finished product and personnel; on the other hand, long-distance transportation requires more forklift operators, which makes the labor cost high. In addition, this scattered and labor-dependent transportation and storage mode is difficult to combine the warehouse with the whole production line, hinders the construction of an integrated intelligent production line, and is not conducive to the further improvement of production efficiency and the precise control of the production process.

DETAILED DESCRIPTION

[0017] The present application will be further described below in conjunction with the drawings.

[0018] As Figures 1 to 11As shown, the carboxymethyl cellulose production line intelligent suspension conveying system comprises a discharge conveying line 1, a circulating suspension conveying line and a plurality of feeding conveying lines 4; the circulating suspension conveying line comprises a ring-shaped conveying guide rail and a plurality of conveying frame bodies 2 connected to the ring-shaped conveying guide rail 3; the discharge conveying line 1 and the feeding conveying line 4 are arranged along the conveying direction of the ring-shaped conveying guide rail 3; the conveying frame body 2 comprises a suspension frame 201 connected to the ring-shaped conveying guide rail 3, an upper fixed plate 206 fixed to the suspension frame 201 and a conveying line support 202 slidingly connected to the upper surface of the fixed plate 206; The inside of the conveying line support 202 is provided with a load conveying line 203; the feeding end side of the feeding conveying line 4 and the discharging end side of the discharge conveying line 1 are both provided with a push conveying line support assembly for pushing the conveying line support 202 to slide on the fixed plate 206; the fixed plate 206 is provided with a support resetting assembly 209 for resetting the conveying line support 202 on the fixed plate 206; the conveying line support 202 is provided with a transmission module 205; the transmission module 205 is used for transmitting the power of the feeding conveying line 4 or the power of the discharge conveying line 1 to the load conveying line 203; The ring-shaped conveying guide rail 3 has no substantial difference from the existing suspension conveying track, and thus is not described in detail; the ring-shaped conveying guide rail 3 is a circulating structure, is suspended and fixed at a certain height, and has a built-in power inside; the suspension frame 201 is carried on the ring-shaped conveying guide rail 3, and the ring-shaped conveying guide rail 3 provides power for the walking of the suspension frame 201; a guide structure is arranged between the suspension frame 201 and the ring-shaped conveying guide rail 3, and the power of the ring-shaped conveying guide rail 3 is connected to the suspension frame 201 for driving the suspension frame 201 to move along the track of the ring-shaped conveying guide rail 3.

[0019] The discharge conveying line 1 and the feeding conveying line 4 both have built-in power, and have no substantial difference from the prior art, and thus are not described in detail; The load conveying line 203 is composed of a plurality of uniformly arranged rollers, each of which is fixed with a synchronous wheel, and each adjacent synchronous wheel is connected with a synchronous belt, so that each roller rotates at the same speed; the surface of the roller is wrapped with a rubber layer to ensure sufficient friction between the roller surface and the packaging bag; and in the design, the horizontal height of the roller gradually decreases towards the suspension frame 201, forming a small inclined plane, which can ensure that the products on the load conveying line 203 will not automatically slide out of the conveying line support 202 away from the suspension frame 201; The product packaged by the packing machine is put into the discharge conveying line 1, and then is sent to the conveying frame body 2 through the discharge conveying line 1. The discharge conveying line 1 is provided with two sensors, one of which is used to sense whether the product reaches the end of the discharge conveying line 1, generates an electric signal to stop the movement of the discharge conveying line 1, and the other sensor is used to sense the arrival of the conveying frame body 2 to generate an electric signal to continue the conveying movement of the discharge conveying line 1 (the sensor can be a proximity switch). When the product is conveyed to the end of the discharge conveying line 1, the discharge conveying line 1 stops rotating and waits to be connected with the next conveying frame body 2. When the discharge conveying line 1 is connected with the conveying frame body 2, the sensor generates an electric signal, and the push conveying line support assembly at the discharge end of the discharge conveying line 1 pushes the conveying line support 202, so that the conveying line support 202 slides relative to the upper fixed plate 206. The upper fixed plate 206 moves at the same speed as the suspension 201, and the conveying line support 202 is stationary relative to the discharge conveying line 1, so the conveying line support 202 slides on the upper fixed plate 206 by a distance. During the alignment of the conveying line support 202 and the discharge conveying line 1, the transmission module 205 connects the end roller at the end of the discharge conveying line 1 with the roller at the end of the load conveying line 203, so that they move at the same speed and in the same direction. The discharge conveying line 1 stably transfers the product to the load conveying line 203. After the product completely enters the load conveying line 203, the push conveying line support assembly leaves the conveying line support 202, and the support resetting assembly 209 resets the conveying line support 202 on the fixed plate 206. Each hopper 5 is connected to an inlet conveying line 4. When a hopper 5 sends a feeding demand, the push conveying line support assembly at the corresponding position of the inlet conveying line 4 receives the signal and starts to work. The remaining push conveying line support assemblies that do not receive the signal will not act on the conveying line support 202. When the conveying frame body 2 moves to the position of the hopper 5 that sends the feeding demand and is aligned with the inlet conveying line 4 of the hopper 5, the push conveying line support assembly pushes the conveying line support 202, so that the conveying line support 202 slides relative to the upper fixed plate 206. The upper fixed plate 206 moves at the same speed as the suspension 201, and the conveying line support 202 is stationary relative to the inlet conveying line 4, so the conveying line support 202 slides on the upper fixed plate 206 by a distance.

[0020] During the alignment of the conveying line support 202 and the inlet conveying line 4, the transmission module 205 connects the end roller at the front end of the conveying line 4 with the roller at the end of the load conveying line 203, so that they move at the same speed. The rotating load conveying line 203 transfers the whole bag of material to the inlet conveying line 4, and then the inlet conveying line 4 conveys the whole bag of material to the hopper 5 for stacking. After the product is completely transferred from the carrier conveying line 203 to the feeding conveying line 4, the pushing conveying line bracket assembly is separated from the conveying line bracket 202, and the bracket resetting assembly 209 resets the conveying line bracket 202 on the fixed plate 206.

[0021] As a preferred mode of the present application, the transmission module 205 comprises a roller bracket 20504, two sliding shafts 20503 fixed on the roller bracket 20504, and a friction wheel 20505 rotatably connected to the roller bracket 20504; the conveying line bracket 202 is fixed with a guide ring 20201 in sliding connection with the sliding shafts 20503; the bottom of the sliding shaft 20503 is fixed with a follower wheel fixing seat 20502; the follower wheel fixing seat 20502 is rotatably connected with a first follower wheel 20501; the upper fixed plate 206 is fixed with a cam support strip 20601; the cam support strip 20601 extends along the sliding direction of the conveying line bracket 202; the cam support strip 20601 is arranged opposite to the first follower wheel 20501; the front end of the cam support strip 20601 is provided with a wedge surface 2060101; In the resetting state of the conveying line bracket 202, the cam support strip 20601 is misaligned with the first follower wheel 20501, so that the roller bracket 20504 is lowered to a position not in contact with the feeding conveying line 4 under the action of its own gravity, ensuring that the friction wheel 20505 does not contact the feeding conveying line 4 without feeding demand; When the feeding conveying line 4 with feeding demand responds, the pushing conveying line bracket assembly pushes the conveying line bracket 202 to slide on the upper fixed plate 206, so that the entire transmission module 205 slides relative to the fixed plate 206; after the first follower wheel 20501 of the sliding transmission module 205 slides onto the surface of the cam support strip 20601 along the wedge surface 2060101, the roller bracket 20504 and the friction wheel 20505 are pushed upward by a distance, so that the body of the friction wheel 20505 is in synchronous contact with the frontmost roller of the feeding conveying line 4 and the rearmost roller of the carrier conveying line 203; the feeding conveying line 4 drives the carrier conveying line 203 to move through the friction wheel 20505, realizing the synchronous movement of the carrier conveying line 203 and the feeding conveying line 4; Similarly, the synchronous movement of the discharging conveying line 1 and the carrier conveying line 203 is also realized through the transmission module 205.

[0022] In the structure, the first follower 20501 can slide along the wedge surface 2060101 to make the cam support strip 20601 so that the friction wheel 20505 is lifted to connect power without the need of the load conveying line 203 to provide power for discharging, so that the conveying frame body 2 in the circulating movement does not need to be connected with the circuit or the air path; and the lifting of the friction wheel 20505 is completed while the conveying line support 202 slides; when the feeding conveying line 4 is butted against the conveying line support 202, the linear speed of the load conveying line 203 is equal to the linear speed of the feeding conveying line 4, so that the energy loss caused by the speed difference during product transfer is reduced.

[0023] As a preferred mode of the present application, the push conveying line support assembly comprises a lower fixed plate 204, a lifting plate 207 and a lifting module connected between the lower fixed plate 204 and the lifting plate 207; the lifting plate 207 is connected with a swing rod 2012; the top surface of the swing rod 2012 is fixed with a hook 201201; the bottom of the conveying line support 202 is fixed with a stop block 20203; the upper fixed plate 206 is provided with a stop block passing groove 20602 at a position opposite to the stop block 20203; the length direction of the stop block passing groove 20602 extends along the sliding direction of the conveying line support 202 on the upper fixed plate 206; The lower fixed plate 204 is fixed on the support of the discharging conveying line 1 or the support of the feeding conveying line 4; Before the conveying line support 202 is aligned with the discharging conveying line 1 or the feeding conveying line 4, the lifting module lifts the lifting plate 207 so that the height of the top end of the hook 201201 is higher than the height of the bottom end of the stop block 20203; when the conveying line support 202 is aligned with the discharging conveying line 1 or the feeding conveying line 4, the hook 201201 is in contact with the stop block 20203, and when the suspension 201 and the upper fixed plate 206 continue to move, the hook 201201 moves relative to the upper fixed plate 206, pulls the stop block 20203 and the conveying line support 202 to move, so that the conveying line support 202 and the hook 201201 are relatively stationary, so that the discharging conveying line 1 or the feeding conveying line 4 is relatively stationary when the product enters or exits the conveying line support 202; After the product is completely transferred from the discharging conveying line 1 to the load conveying line 203 or from the load conveying line 203 to the feeding conveying line 4, the swing rod 2012 is lowered, the hook 201201 is unhooked from the stop block 20203, and the support resetting assembly 209 resets the conveying line support 202 on the fixed plate 206; when the feeding conveying line 4 at the corresponding position needs to be supplied, the lifting module at the position needs to lift the lifting plate 207, and the lifting modules at the other positions are lowered first, and the lifting module responds to the supply demand to complete the alternate feeding.

[0024] As a preferred mode of the present application, one end of the swing lever 2012 away from the hook 201201 is rotatably connected to the lifting top plate 207 through the rotating shaft 2014; the swing lever 2012 is fixed with a movable block 201202; the lifting top plate 207 is fixed with a fixed block 20701 in the rotating direction of the movable block 201202; the rotating shaft 2014 is sleeved with a torsional spring 2015; both ends of the torsional spring 2015 are fixed on the swing lever 2012 and the lifting top plate 207 respectively; the swing lever 2012 is rotatably connected with a second follower wheel 201203; the bottom surface of the upper fixed plate 206 is fixed with a wedge-shaped block 20603; the wedge-shaped block 20603 is arranged on the path of movement of the second follower wheel 201203; Under the action of the torsional spring 2015, the swing lever 2012 has a tendency to turn upward for resetting, and the movable block 201202 cannot continue to rotate under the blockage of the fixed block 20701, so the position of the swing lever 2012 under the blockage of the fixed block 20701 is the reset position; during the traction of the hook 201201 to the block 20203, the second follower wheel 201203 gradually approaches the wedge-shaped block 20603, and when the products of the load conveying line 203 are completely transferred from the load conveying line 203 to the feeding conveying line 4 or from the discharging conveying line 1 to the load conveying line 203, the second follower wheel 201203 contacts with the wedge-shaped block 20603, the wedge-shaped block 20603 pushes the swing lever 2012 to turn over by the second follower wheel 201203 against the elastic force of the torsional spring 2015, so that the hook 201201 is separated from the block 20203, and the conveying line support 2020 is reset by the support resetting assembly 209 on the upper fixed plate 6. The wedge-shaped block 20603 is disengaged from the second follower wheel 201203, and the swing lever 2012 is reset to the position where the movable block 201202 is pressed against the fixed block 20701, preparing for the next conveying frame body 2. With this structure, when continuous feeding is needed for the feeding conveying line 4, the lifting top plate 207 at the corresponding position needs to be lifted urgently, and the lifting top plate 207 at the corresponding position of the feeding conveying line 4 does not need to be lowered to a position not blocking the circulation of the block 20203, so it is not necessary to control the lifting module every time the material is fed, the workload of the lifting module is reduced, and the control circuit is simplified.

[0025] As a preferred mode of the present application, the lifting module comprises a lifting cylinder 2010, a lifting guide sleeve 208 fixed on the lower fixed plate 204, and a lifting guide shaft 2013 fixed on the lifting plate 207; both ends of the lifting cylinder 2010 are fixed on the lifting plate 207 and the lower fixed plate 204 respectively; the lifting guide shaft 2013 is slidingly connected to the lifting guide sleeve 208; The lifting cylinder 2010 drives the lifting plate 207 to slide along the length direction of the lifting guide sleeve 208.

[0026] As a preferred mode of the present application, the bottom of the conveying line support 202 is fixed with a translation guide sleeve 20202; the upper fixed plate 206 is fixed with a horizontal sliding shaft 2011 slidingly connected to the translation guide sleeve 20202; The conveying line support 202 and the upper fixed plate 206 are slidingly connected through the translation guide sleeve 20202 and the horizontal sliding shaft 2011.

[0027] As a preferred mode of the present application, the support reset assembly 209 comprises a steel cable 20901 and a fixed cylinder 20903 fixed on the upper fixed plate 206; the fixed cylinder 20903 is internally provided with a counterweight 20904; the upper fixed plate 206 is fixed with a reversing wheel 20902; one end of the steel cable 20901 is fixed on the conveying line support 202; the other end of the steel cable 20901 is fixedly connected to the counterweight 20904 in the fixed cylinder 20903 after passing through the reversing wheel 20902; The reversing wheel 20902 is composed of two grooved rollers which are clamped to the steel cable 20901 so that the steel cable 20901 cannot derail from the reversing wheel 20902; the fixed cylinder 20903 is used for limiting the counterweight 20904 to prevent the counterweight 20904 from shaking; the counterweight 20904 provides a constant pulling force for the steel cable through the steel cable 20901, which is used for resetting the conveying line support 202 and is more suitable for long-distance resetting than a spring.

[0028] As a preferred mode of the present application, the counterweight 20904 is in a tank structure; the top of the tank structure is provided with a filling pipe 2090401; a notch 2090301 is formed in the side wall of the fixed cylinder 20903; a sealing plug is arranged on the filling pipe 2090401; the sealing plug is used for sealing the filling pipe 2090401 to prevent the liquid in the tank structure from evaporating; water is injected into the tank structure, the weight of the water can be added according to the required pulling force of the counterweight, so as to facilitate controlling the pulling force of the steel cable 20901 for resetting the conveying line support 202; the pulling force received by the conveying line support 202 can be controlled to be as small as possible, as long as the resetting before the next feeding or discharging is ensured.

[0029] Because the energy consumed by the annular conveying guide rail 3 in the conveying process is used to store the gravitational potential energy when the counterweight 20904 is lifted, the weight of the counterweight 20904 is as small as possible, as long as the conveying line support 202 can be reset, thereby reducing the energy loss of the annular conveying guide rail 3. The filling amount of the tank structure is easy to adjust and convenient to debug; the tank structure can be filled with water through the gap 2090301.

[0030] The beneficial effects of the present application are: 1. When the conveying frame main body is docked with the feeding conveying line or the discharging conveying line, the annular conveying guide rail does not need to stop to complete automatic docking, thereby improving the transfer efficiency of the product.

[0031] 2. The product is transferred from the discharging conveying line to the corresponding bin by the annular conveying guide rail, which can realize long-distance conveying, reduce labor intensity, reduce safety hazards, reduce production cost, and improve conveying efficiency.

[0032] 3. The end of the production line and the warehouse are combined into a coherent system through the conveying system, which is convenient for building an intelligent production line.

[0033] 4. The friction wheel lifting action is completed while the conveying line support slides, and the load conveying line does not need to be powered for unloading, so that the circulating conveying frame main body does not need to be connected to the circuit or air circuit; when the feeding conveying line is docked with the conveying line support, the linear velocity of the load conveying line is equal to that of the feeding conveying line, thereby reducing the energy loss caused by the speed difference during product transfer.

[0034] 5. When the corresponding feeding conveying line needs continuous feeding, the lifting plate at the corresponding position needs to be lifted urgently, and the lifting plate at the corresponding position of the feeding conveying line does not need to be lowered to a position that does not hinder the circulation of the stop block, so that the lifting module does not need to be controlled every time the product is fed, thereby reducing the workload of the lifting module and simplifying the control circuit.

[0035] The above is only the preferred embodiment of the present application, and any equivalent changes or modifications made in accordance with the structure, features and principles described in the patent application scope of the present application are included in the patent application scope of the present application.
