Description

Technical Field

[0001] This invention relates to the field of carboxymethyl cellulose production line technology, and in particular to an intelligent overhead conveyor system for a carboxymethyl cellulose production line. Background Technology

[0002] Carboxymethyl cellulose (CMC) is a cellulose derivative obtained by chemical modification of natural cellulose. Its preparation typically involves alkalizing cellulose under alkaline conditions, followed by reaction with etherifying agents such as chloroacetic acid to introduce carboxymethyl groups, thereby forming a water-soluble polymer. CMC is mostly a white or slightly yellow powder, odorless and tasteless, readily soluble in water to form a colloidal solution with a certain viscosity, exhibiting various properties such as thickening, binding, emulsification, suspension, and stabilization. Based on these properties, it is widely used in the food industry, pharmaceutical field, daily chemical industry, as well as textile, papermaking, and oil drilling industries, making it an important water-soluble polymer material.

[0003] The production of carboxymethyl cellulose requires a series of continuous processes, mainly including raw material loading, raw material crushing, alkalization reaction, etherification reaction, neutralization, ethanol washing, centrifugation, drying, crushing and sieving, finished product packaging and finished product storage.

[0004] In the aforementioned production process, after carboxymethyl cellulose is packaged, it is typically transported by forklift to various warehouses for stacking and storage. However, this current method of finished product warehousing and transportation presents several problems: Firstly, due to the large number of warehouses and the considerable distance between them and the finished product packaging stations, each pallet of finished product requires a long-distance transport by forklift from the finished product packaging exit to the corresponding warehouse. This results in extremely low automation of the entire transportation process, relying entirely on manual forklift operation. This not only significantly increases the labor intensity of workers but also poses safety risks such as collisions and falls due to road conditions and operational factors during long-distance forklift transportation, threatening the safety of both finished products and personnel. Secondly, long-distance transportation requires a large number of forklift operators, leading to high labor costs. Furthermore, this decentralized, manual-dependent transportation and warehousing model makes it difficult to organically integrate warehouses with the entire production line, hindering the construction of an integrated intelligent production line and impeding further improvements in production efficiency and precise control of the production process.

[0043] The invention will now be further described with reference to the accompanying drawings.

[0044] like Figures 1 to 11 As shown, the intelligent suspended conveying system for a carboxymethyl cellulose production line of the present invention includes an output conveying line 1, a circulating suspended conveying line, and multiple infeed conveying lines 4; the circulating suspended conveying line includes an annular conveying guide rail 3 and multiple conveying frame bodies 2 connected to the annular conveying guide rail 3; the output conveying line 1 and the infeed conveying lines 4 are arranged along the conveying direction of the annular conveying guide rail 3; the conveying frame body 2 includes a suspension 201 connected to the annular conveying guide rail 3, an upper fixing plate 206 fixed to the suspension 201, and a conveying line bracket 202 slidably connected to the upper surface of the upper fixing plate 206;

[0045] The conveyor support 202 is internally provided with a material conveying line 203; both the infeed end of the feeding conveyor 4 and the discharge end of the discharge conveyor 1 are provided with a pusher conveyor support assembly for pushing the conveyor support 202 to slide on the upper fixed plate 206; the upper fixed plate 206 is provided with a support reset assembly 209 for resetting the conveyor support 202 on the upper fixed plate 206; the conveyor support 202 is provided with a transmission module 205; the transmission module 205 is used to transmit the power of the feeding conveyor 4 or the discharge conveyor 1 to the material conveying line 203.

[0046] The annular conveying guide rail 3 is not fundamentally different from the existing suspended conveying rail, so it will not be described in detail. The annular conveying guide rail 3 is a loop structure. The annular conveying guide rail 3 is suspended and fixed at a certain height, and the annular conveying guide rail 3 has its own internal power. The suspension 201 is mounted on the annular conveying guide rail 3, and the annular conveying guide rail 3 provides power for the movement of the suspension 201. A guide structure is set between the suspension 201 and the annular conveying guide rail 3, and the power of the annular conveying guide rail 3 is connected to the suspension 201 to drive the suspension 201 to move along the trajectory of the annular conveying guide rail 3.

[0047] Both the discharge conveyor line 1 and the feed conveyor line 4 are self-powered and are not fundamentally different from existing technologies, so they will not be discussed in detail.

[0048] The material conveyor line 203 consists of multiple evenly arranged rollers, each with a synchronous pulley fixed on it. A synchronous belt connects adjacent synchronous pulleys, enabling all rollers to rotate at the same speed. The surface of the rollers is covered with a rubber layer to ensure sufficient friction between the roller surface and the packaging bag. Furthermore, the horizontal height of the rollers gradually decreases towards the suspension 201, forming a small inclined surface, which ensures that the products on the material conveyor line 203 will not automatically slide off the conveyor support 202 away from the suspension 201.

[0049] After the packaged product is placed into the discharge conveyor line 1, it is fed into the conveyor frame body 2. Two sensors are installed on the discharge conveyor line 1: one senses whether the product has reached the end of the line and generates an electrical signal to stop the line; the other sensor senses the arrival of the conveyor frame body 2 and generates an electrical signal to allow the line to continue moving (the sensor can be a proximity switch). When the product reaches the end of the discharge conveyor line 1, it stops rotating and waits to dock with the next conveyor frame body 2. When the discharge conveyor line 1 docks with the conveyor frame body 2, the sensor generates an electrical signal. In the process of material discharge, the pusher assembly at the discharge end of the discharge conveyor line 1 pushes the conveyor support 202, causing the conveyor support 202 to slide relative to the upper fixed plate 206. The upper fixed plate 206 moves at the same speed as the suspension 201, while the conveyor support 202 remains stationary relative to the discharge conveyor line 1. Therefore, the conveyor support 202 slides a certain distance on the upper fixed plate 206. During the alignment of the conveyor support 202 with the discharge conveyor line 1, the transmission module 205 connects one end roller of the discharge conveyor line 1 with the last roller of the loading conveyor line 203, causing them to move at the same speed and in the same direction. The discharge conveyor line 1 smoothly transfers the product onto the loading conveyor line 203.

[0050] After the product has fully entered the material conveyor line 203, the pusher conveyor line bracket assembly leaves the conveyor line bracket 202, and the bracket reset assembly 209 resets the conveyor line bracket 202 on the upper fixing plate 206.

[0051] Each hopper 5 is connected to a feeding conveyor line 4. When a hopper 5 sends a feeding request, the push conveyor support assembly at the corresponding position of the feeding conveyor line 4 receives the signal and starts working. The other push conveyor support assemblies that do not receive a signal will not act on the push conveyor support 202. When the conveyor frame body 2 moves to the position of the hopper 5 with the feeding request and is directly opposite the feeding conveyor line 4 of that hopper 5, the push conveyor support assembly pushes the conveyor support 202, causing the conveyor support 202 to slide relative to the upper fixed plate 206. The upper fixed plate 206 moves at the same speed as the suspension 201, while the conveyor support 202 is stationary relative to the feeding conveyor line 4. Therefore, the conveyor support 202 slides a certain distance on the upper fixed plate 206.

[0052] During the time when the conveyor support 202 is aligned with the feeding conveyor 4, the transmission module 205 connects the frontmost roller of the conveyor 4 with the last roller of the loading conveyor 203, so that the two move at the same speed; the rotating loading conveyor 203 transfers the whole bag of material to the feeding conveyor 4, and then the feeding conveyor 4 transports the whole bag of material to the hopper 5 for stacking.

[0053] After the product has completely entered the feeding conveyor line 4 from the loading conveyor line 203, the pusher conveyor line bracket assembly moves away from the conveyor line bracket 202, and the bracket reset assembly 209 resets the conveyor line bracket 202 on the upper fixing plate 206.

[0054] In a preferred embodiment of the present invention, the transmission module 205 includes 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; a guide ring 20201 slidably connected to the sliding shafts 20503 is fixed on the conveyor line bracket 202; a follower wheel fixing seat 20502 is fixed at the bottom of the sliding shafts 20503; a first follower wheel 20501 is rotatably connected to the follower wheel fixing seat 20502; a cam support bar 20601 is fixed on the upper fixing plate 206; the cam support bar 20601 extends along the sliding direction of the conveyor line bracket 202; the cam support bar 20601 is positioned directly opposite the first follower wheel 20501; and a wedge-shaped surface 2060101 is provided at the front end of the cam support bar 20601.

[0055] When the conveyor support 202 is in the reset state, the cam support bar 20601 is misaligned with the first follower wheel 20501. Therefore, due to its own gravity, the roller support 20504 causes the friction wheel 20505 to descend to a position that does not contact the feeding conveyor 4, ensuring that the friction wheel 20505 will not contact the feeding conveyor 4 which does not require feeding.

[0056] When the feeding conveyor line 4 responds to the feeding demand, the pusher conveyor support assembly will push the conveyor support 202 to slide on the upper fixed plate 206, so that the entire transmission module 205 slides relative to the upper fixed plate 206. After sliding, the first follower wheel 20501 of the transmission module 205 slides along the wedge surface 2060101 to the surface of the cam support bar 20601. The roller support 20504 and the friction wheel 20505 are pushed upward a distance, so that the wheel body of the friction wheel 20505 contacts the frontmost roller of the feeding conveyor line 4 and the rearmost roller of the carrying conveyor line 203 synchronously. The feeding conveyor line 4 drives the carrying conveyor line 203 to move through the friction wheel 20505, so that the carrying conveyor line 203 and the feeding conveyor line 4 move at the same speed.

[0057] Similarly, the docking and synchronous movement of the discharge conveyor line 1 and the loading conveyor line 203 are also achieved through the transmission module 205.

[0058] In this structure, when the conveyor support 202 is aligned with the feeding conveyor 4 or the discharging conveyor 1, the first follower wheel 20501 slides along the wedge surface 2060101 to the cam support bar 20601, causing the friction wheel 20505 to rise and connect the power. This eliminates the need for the loading conveyor 203 to have its own power for unloading, and the conveyor frame body 2 in cyclic motion does not need to be connected to the circuit or air circuit. Moreover, the friction wheel 20505 rises simultaneously with the sliding of the conveyor support 202. When the feeding conveyor 4 is connected to the conveyor support 202, the linear speed of the loading conveyor 203 is equal to that of the feeding conveyor 4, reducing energy loss caused by speed differences during product transfer.

[0059] In a preferred embodiment of the present invention, the pusher conveyor support assembly includes a lower fixed plate 204, a lifting plate 207, and a lifting module connecting the lower fixed plate 204 and the lifting plate 207; a swing rod 2012 is connected to the lifting plate 207; a hook 201201 is fixed on the top surface of the swing rod 2012; a stop block 20203 is fixed at the bottom of the conveyor support 202; an over-stop groove 20602 is provided on the upper fixed plate 206 at a position directly opposite the stop block 20203; the length direction of the over-stop groove 20602 extends along the direction in which the conveyor support 202 slides on the upper fixed plate 206;

[0060] The lower fixing plate 204 is fixed on the bracket of the discharge conveyor line 1 or the bracket of the feed conveyor line 4;

[0061] Before the conveyor support 202 is aligned with the discharge conveyor 1 or the feed conveyor 4, the lifting module raises the top plate 207, so that the height of the top of the hook 201201 is higher than the height of the bottom of the stop block 20203. When the conveyor support 202 is aligned with the discharge conveyor 1 or the feed conveyor 4, the hook 201201 contacts the stop block 20203. As the suspension 201 and the upper fixed plate 206 continue to move, the hook 201201 moves relative to the upper fixed plate 206, pulling the stop block 20203 and the conveyor support 202 to move, so that the conveyor support 202 and the hook 201201 are relatively stationary, so that when the product enters or exits the conveyor support 202, it is always relatively stationary with respect to the discharge conveyor 1 or the feed conveyor 4.

[0062] After the product has completely entered the loading conveyor line 203 from the discharge conveyor line 1 or exited the loading conveyor line 203 into the feeding conveyor line 4, the swing arm 2012 descends, the hook 201201 disengages from the stop block 20203, and the bracket reset assembly 209 resets the conveyor line bracket 202 on the upper fixed plate 206. When the corresponding feeding conveyor line 4 has a feeding demand, the lifting module at that position needs to lift the top plate 207, while the lifting modules at other positions first lower the top plate 207. The lifting modules respond according to the feeding demand, which can complete the alternating feeding.

[0063] In a preferred embodiment of the present invention, one end of the swing rod 2012 away from the hook 201201 is rotatably connected to the rising top plate 207 via a rotating shaft 2014; a movable stop 201202 is fixed on the swing rod 2012; a fixed stop 20701 is fixed on the rising top plate 207 in the rotation direction of the movable stop 201202; a torsion spring 2015 is sleeved on the rotating shaft 2014; the two ends of the torsion spring 2015 are respectively fixed to the swing rod 2012 and the rising top plate 207; a second follower wheel 201203 is rotatably connected to the swing rod 2012; a wedge block 20603 is fixed on the bottom surface of the upper fixed plate 206; the wedge block 20603 is disposed on the path of the movement of the second follower wheel 201203;

[0064] Under the force of the torsion spring 2015, the swing arm 2012 tends to flip upwards, which is used to reset the swing arm 2012. The movable stop block 201202 cannot continue to rotate due to the obstruction of the fixed stop block 20701. Therefore, the position where the movable stop block 201202 is blocked by the fixed stop block 20701 is the reset position of the swing arm 201202. During the process of the hook 201201 pulling the stop block 20203, the second follower wheel 201203 gradually approaches the wedge block 20603, when the material conveyor line... After the product 203 has completely entered the feeding conveyor line 4 from the loading conveyor line 203 or completely entered the loading conveyor line 203 from the discharge conveyor line 1, the second follower wheel 201203 contacts the wedge block 20603. The wedge block 20603, through the second follower wheel 201203, pushes the swing arm 2012 to overcome the elastic force of the torsion spring 2015 and flip, causing the hook 201201 to separate from the stop block 20203. The conveyor support 2020 is reset on the upper fixed plate 6 due to the support reset assembly 209. As the upper fixed plate 206 continues to move relative to the lifting plate 207, the wedge block 20603 disengages from the second follower wheel 201203, and the force of the torsion spring 2015 causes the swing arm 2012 to reset to the movable stop block 201202 and be pressed back onto the fixed stop block 20701 for positioning, preparing for the next conveyor frame body 2.

[0065] With this structure, when the corresponding feeding conveyor line 4 needs to feed continuously, it is necessary to raise the corresponding lifting top plate 207, instead of lowering the corresponding lifting top plate 207 of the feeding conveyor line 4 to a position that does not obstruct the cyclic movement of the stop block 20203. There is no need to control the lifting module for each feeding, which reduces the workload of the lifting module and simplifies the control circuit.

[0066] In a preferred embodiment of the present invention, the lifting module includes 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; the two ends of the lifting cylinder 2010 are respectively fixed on the lifting plate 207 and the lower fixed plate 204; the lifting guide shaft 2013 is slidably connected to the lifting guide sleeve 208;

[0067] The lifting cylinder 2010 drives the lifting plate 207 to slide up and down along the length of the lifting guide sleeve 208.

[0068] In a preferred embodiment of the present invention, a translational guide sleeve 20202 is fixed to the bottom of the conveyor support 202; a horizontal sliding shaft 2011 that is slidably connected to the translational guide sleeve 20202 is fixed on the upper fixing plate 206.

[0069] The conveyor support 202 and the upper fixed plate 206 are slidably connected by a translational guide sleeve 20202 and a horizontal sliding shaft 2011.

[0070] In a preferred embodiment of the present invention, the bracket reset assembly 209 includes a steel cable 20901 and a fixing cylinder 20903 fixed on the upper fixing plate 206; a counterweight 20904 is disposed inside the fixing cylinder 20903; a reversing wheel 20902 is fixed on the upper fixing plate 206; one end of the steel cable 20901 is fixed on the conveyor support 202; the other end of the steel cable 20901 passes around the reversing wheel 20902 and is fixedly connected to the counterweight 20904 inside the fixing cylinder 20903;

[0071] The reversing wheel 20902 consists of two grooved rollers that clamp onto the steel cable 20901, preventing the steel cable 20901 from derailing from the reversing wheel 20902. The fixed cylinder 20903 is used to limit the counterweight 20904 and prevent it from swaying. The counterweight 20904 provides a constant tension to the steel cable through the traction of the steel cable 20901 on the conveyor support 202. This tension is used for the reset of the conveyor support 202 and is more suitable for long-distance reset than a spring.

[0072] In a preferred embodiment of the present invention, the counterweight 20904 is a tank structure; a filling pipe 2090401 is provided on the top of the tank structure; a notch 2090301 is provided on the side wall of the fixed cylinder 20903; a sealing plug is provided on the filling pipe 2090401 to seal the filling pipe 2090401 and prevent the liquid inside the tank structure from evaporating; water is injected into the tank structure, and the weight of water added can be adjusted according to the required tension of the counterweight, which facilitates the control of the tension of the steel cable 20901 on the reset of the conveyor support 202; so that the tension received by the conveyor support 202 can be controlled to be as small as possible, as long as it is ensured to be reset before the next feeding or discharging.

[0073] Because part of the energy consumed by the annular conveyor rail 3 during the conveying process is used to lift the gravitational potential energy stored in the counterweight 20904, the weight of the counterweight 20904 should be as small as possible, just enough to reset the conveyor support 202, thus reducing the energy loss of the annular conveyor rail 3. The filling amount of the tank structure is easy to adjust and convenient to debug; water can be added to the tank structure through the notch 2090301.

[0074] The beneficial effects of this invention are as follows:

[0075] 1. When the main body of the conveyor frame is connected to the feeding or discharging conveyor line, the connection can be completed automatically without stopping the circular conveyor rail, thus improving the product transfer efficiency.

[0076] 2. By using a circular conveyor rail to transfer products from the discharge conveyor line to the corresponding hopper, long-distance transportation can be achieved, reducing labor intensity, safety hazards, production costs, and improving transportation efficiency.

[0077] 3. By connecting the end of the production line and the warehouse into a coherent system through a conveyor system, it is easier to build a smart and intelligent production line.

[0078] 4. The friction wheel lift action is completed simultaneously with the sliding of the conveyor support, eliminating the need for the material conveyor to have its own power for unloading. This means that the main body of the circulating conveyor frame does not need to be connected to electrical circuits or air circuits. When the feeding conveyor is connected to the conveyor support, the linear speed of the material conveyor is equal to that of the feeding conveyor, reducing energy loss caused by speed differences during product transfer.

[0079] 5. When the corresponding feeding conveyor line needs to continuously feed, it is necessary to raise the corresponding lifting top plate, instead of lowering the corresponding lifting top plate of the feeding conveyor line to a position that does not obstruct the cyclic movement of the stop block. It is not necessary to control the lifting module for each feeding, which reduces the workload of the lifting module and simplifies the control circuit.

[0080] The above description is only a preferred embodiment of the present invention. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of this patent application are included in the scope of this patent application.
