Description

Technical Field

[0001] The invention relates to the technical field of cigarette sheet glue production, and in particular to a cigarette sheet glue production system and process. Background Art

[0002] Smoked rubber is a natural rubber commodity. Its current production process is as follows:

[0003] (1) Collection and processing of latex: Collect fresh natural rubber latex and purify it to remove impurities;

[0004] (2) Coagulation: After filtering and removing impurities from the latex, diluting it with water, and then adding acid for coagulation treatment, the latex is coagulated into a rubber block;

[0005] (3) Slicing and tableting process: After the solidified rubber block is cut into films, it is pressed into thin slices by a tablet press to facilitate the subsequent smoking process;

[0006] (4) Smoking and drying: The pressed sheets are smoked and dried. This step is a key step in the production of smoked sheet glue. Smoking not only provides the sheets with a unique smoky smell, but also improves their anti-aging and anti-corrosion properties.

[0038] A crimping member is hinged to the output end of the driving member, and during crimping, the driving member drives the crimping member to press downward;

[0039] The limiting member is arranged at the hinge between the crimping member and the driving member, and is used to make the crimping member tilt toward the sheet pressing mechanism.

[0040] Furthermore, the film hanging rod device comprises:

[0049] The rod moving mechanism is used to move the hanging rod on the rod moving station of the hanging rod arranging mechanism to the hanging rack.

[0050] Furthermore, the tableting mechanism is composed of a multi-stage pressing roller, and a conveying water pool is arranged between the multi-stage pressing rollers. There is water flowing from upstream to downstream in the conveying water pool, which is used to convey the tablets downstream and wash the tablets with water.

[0051] The present invention also provides a tobacco sheet glue production process based on the tobacco sheet glue production equipment, comprising:

[0052] Coagulation step: The purified latex is coagulated by adding acid to form a cylindrical gel with a through hole in the middle.

[0053] The purification process of latex is as follows: the fresh latex entering the factory is uniformly collected in the collection pool; after filtration, the fresh latex flows into the mixing pool; in the mixing pool, the dry content meter and pH meter are used to automatically detect the dry content and ammonia content of the fresh latex online, and the relevant data are uploaded after the detection is completed. Finally, the dry content of the fresh latex is automatically prepared by the dry content preparation system. When the latex in the mixing pool meets the production process requirements, the latex is transferred to the buffer tank of the filling machine by a pump, and together with the acid addition system, the latex and acid are quantitatively poured into the gel barrel. After automatic stirring, foaming, and capping, the robot places multiple gel barrels on the pallet. After completing a gel barrel stack, it is sent to the coagulation warehouse by an electric ground cow for the gel process.

[0054] Film making steps: the solidified cylindrical gel is transferred to the cylindrical gel cutting device, and the cylindrical gel cutting device cuts the film into films. The films are pressed by the film pressing mechanism and then transported to the film hanging rod equipment for cutting and hanging. During the film making process, the film is transported and washed by a cleaning solution between each process. The specific film making process is as follows:

[0055] The electric ground bull moves the gel barrel that has completed the gel process requirements to the cylindrical gel cutting device, overturns the gel barrel, and pours the cylindrical gel into the first buffer pool. The water in the first buffer pool can clean the acid on the surface of the cylindrical gel. After manually inserting the mandrel in the center of the cylindrical gel, it is cut into sheets by the rotary cutting mechanism 11. The sheets are pressed by the sheet pressing mechanism and then sent to the film hanging rod equipment by the conveyor belt. During the sheet pressing process, the water flowing from upstream to downstream in the conveying water pool transports the sheets downstream and washes the sheets with water for acid treatment. The sheets that have completed sheet pressing are sent to the film hanging rod equipment, cut into films and hung on the hanging rods. The hanging rods are group hanging rods, that is, multiple films are hung on the same hanging rod.

[0056] Shelving steps: The automatic racking device moves the hanging rod full of films to the rack;

[0057] Drying steps: move the rack with the film to the drying section for drying. The drying includes an initial fumigation stage, a constant speed drying stage and a speed reduction drying stage. The temperature of the initial fumigation stage is 48-50°C and the drying time is 3-4h; the temperature of the constant speed drying stage is 70-75°C and the moisture content of the film is <10%; the temperature of the speed reduction drying stage is 70-75°C, the drying time is 2-3 days, and the moisture content is <0.5%.

[0058] After drying, the products are shipped out of the warehouse, inspected and graded, and then packaged according to grade.

[0059] Compared with the prior art, the present invention has the following beneficial effects:

[0060] (1) The present invention realizes the automated and continuous production of latex to cigarette sheet glue, greatly reduces labor input, improves production efficiency, and ensures the quality and consistency of the film.

[0061] (2) The uniformity of the slice thickness is ensured. At the same time, the connecting mechanism is used to connect the front and rear sheets to form a continuous sheet, so that the film with the same length can be obtained by putting it into the cutting mechanism, ensuring the uniformity of the external dimensions of the final product.

[0062] (3) After the hanging rod arrangement mechanism of the automatic hanging rack equipment realizes the centralized and regular arrangement of the hanging rods, the hanging rods are moved to the hanging racks by the rod shifting mechanism, thereby realizing the automatic shelving of the tobacco sheet glue, achieving the purpose of replacing manual operation and meeting the requirements of efficient and reliable automated production.

DETAILED DESCRIPTION

[0091] The present invention will be further described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0092] Example 1

[0093] like Figure 1-2As shown, the present invention provides a tobacco sheet glue production system, including: a pretreatment section, a filling section, a section making section, a loading and unloading section and a drying section. The pretreatment section is provided with a collecting pool and a summarizing pool. The fresh latex entering the factory is uniformly collected in the collecting pool. After filtration, the fresh latex flows into the mixing pool. In the mixing pool, a dry content meter and a pH value meter are used to automatically online detect the dry content and the ammonia content of the fresh latex in turn. After the detection is completed, relevant data is uploaded. Finally, the dry content of the fresh latex is prepared by a dry content preparation system. After preparation to meet the production requirements, the latex is transferred to the filling machine buffer tank of the filling section by a pump, and together with the acid adding system, the latex and acid are quantitatively poured into the gel barrel. After automatic stirring, foaming and capping, a plurality of gel barrels are placed on a tray by a robot arm, and transported to the coagulation warehouse for coagulation by an AGV. The solidified cylindrical gel is transferred and capped before being sent to the production segment. After being cut into slices, overlapped, pressed and cut, the slices are hung on the long hanging rod 7 in the form of a group, and then sent to the loading and unloading section. The hanging rod 7 full of films is moved to the hanging rack 63 by the automatic hanging rack device 6, and then the hanging rack 63 with the film 82 is moved to the drying section for drying. The drying process includes the initial fumigation stage, the constant speed drying stage and the speed reduction drying stage. The temperature of the initial fumigation stage is 48-50℃, and the drying time is 3-4h; the temperature of the constant speed drying stage is 70-75℃, and the moisture content of the film is less than 10%; the temperature of the speed reduction drying stage is 70-75℃, the drying time is 2-3 days, and the moisture content is less than 0.5%. After drying, it is transported out of the warehouse, tested and graded, and then packaged according to the grade.

[0094] Specifically, Figure 3As shown, the film making equipment for making the film comprises: a cylindrical gel cutting device 1, a lap joint mechanism 2, a film pressing mechanism 3 and a film hanging rod device 5. The cylindrical gel cutting device 1 comprises a feeding mechanism, a rotary cutting mechanism 11, a first buffer pool 12 and a material roller 14. The first buffer pool 12 is located on the feeding side of the rotary cutting mechanism 11 and contains water. After the cylindrical gel 8 is fed into the first buffer pool 12, the gel 8 is suspended on the water due to the buoyancy, which is convenient for the movement of the gel 8 and the subsequent installation of the core shaft 131. At the same time, the water in the first buffer pool 12 will clean the acid on the surface of the gel to achieve the purpose of acid cleaning. The belt roller 14 is located above the rotary cutting mechanism 11. The feeding mechanism feeds the gel 8 to the belt roller 14 and the rotary cutting mechanism 11. The gel 8 contacts the belt roller 14. The belt roller 14 rotates to drive the gel 8 to rotate around the core shaft 131. At the same time, the rotary cutter of the rotary cutting mechanism 11 cuts the rotating gel 8. The gel 8 continues to feed while cutting, thereby realizing continuous slicing of the cylindrical gel 8. The overlapping section is located downstream of the feeding rotary cutting section, specifically at the discharge end of the rotary cutting mechanism 11. It includes a second buffer pool 21 and an overlapping mechanism. The second buffer pool 21 stores water, and its end is connected to the downstream pressing roller 3. It is mainly used for acid washing of the slices formed by rotary cutting, as well as caching the slices and providing buoyancy, so as to overlap and transport the two sheets before and after, and form a continuous film after being pressed by the pressing roller 3.

[0095] Specifically, Figure 4-6 As shown, the feeding mechanism includes: an annular feeding chain 13 and a transmission assembly. The annular feeding chain 13 is composed of two chains and a plurality of sprockets. The two chains are transmitted through a first transmission shaft 133 to achieve synchronization of the two chains. A plurality of detachable core shafts 131 are arranged between the two chains. In this embodiment, the core shaft 131 is connected to the chains at both ends by a snap-on method, that is, a snap seat is arranged on the chain, and then the two ends of the core shaft 131 are respectively snapped into the two snap seats to achieve the installation of the core shaft 131, so that the core shaft 131 moves with the annular feeding chain 13. It should be noted that the low position of the chain should be located below the water surface of the first buffer pool 12, so that the core shaft 131 is immersed in water during low-position transportation, and the gel 8 thereon is immersed in water as much as possible to ensure the acid washing effect.

[0096] One end of the first transmission shaft 133 is a manual feed wheel 132, and the other end is connected to the power shaft of the peeling mechanism 11 through a transmission assembly, so that the power of the peeling mechanism 11 can be introduced into the annular feed chain 13 to drive the annular feed chain 13 to automatically feed, that is, to realize the automatic feeding of the gel 8. The feeding speed of the gel 8 is adapted to the peeling mechanism 11 to ensure that the thickness of the slices formed by cutting is uniform. Specifically, the transmission assembly includes a second transmission shaft 134, one end of the second transmission shaft 134 is connected to the power shaft of the peeling mechanism 11 through a gear, and the other end is connected to the first transmission shaft 133 through a sprocket chain. A clutch 135 is provided on the second transmission shaft 134 for cutting off the power, so that in special circumstances, the manual feed wheel 132 can be manually rotated to realize the manual feeding of the gel 8. In this embodiment, the basic parameters of the peeling mechanism 11 are shown in Table 1:

[0097] Table 1

[0098] power About 4kW Applicable gel size (cylindrical) ≤Φ800X500 Peeling speed About 680m / h Gel processing capabilities About 6200kg / h Gel time of rotary cutting About 30 seconds Slice thickness (adjustable) 20±5mm

[0099] Furthermore, when the rotary cutter is rotary cutting, the rotary cutter rotates, which generates a lateral force on the gel 8, causing the position of the cut slice to shift. At the same time, the gel 8 is elastic, resulting in uneven thickness of the cut slice, and even a large difference in thickness between the left and right sides of the same slice. Therefore, the upper surface of the belt roller 14 of the present invention is provided with a pattern, and the pattern faces the moving direction of the rotary cutter. The roller surface pattern is used to provide a reverse force for the gel 8 to offset the force of the rotary cutter on it, which can effectively solve the problem of slice shift and uneven thickness.

[0100] like Figure 7 As shown, the overlapping mechanism includes: a material discharging detection sensor 231, a clamping unit 232, a material breaking detection sensor 234 and a crimping unit 233. The clamping unit 232 is conveyed in a circular manner by the conveying chain 22. Two opposite clamping units 232 are respectively located on both sides of the sheet 81 to clamp the head of a sheet 81 together. Figure 8-10 As shown, since the upstream peeling speed is relatively fast, the finished sheet 81 is in a thrown-out state when it leaves the conveying roller. In order to facilitate the subsequent clamping of the finished sheet by the clamping unit 232, the present invention is connected with a downwardly inclined blanking plate 235 at the discharge point of the peeling mechanism 11. The blanking plate 235 is used to receive the thrown-out finished sheet 81 and play a guiding role, thereby ensuring that the clamping unit 232 can accurately clamp the finished sheet 81.

[0101] The discharge detection sensor 231 is arranged at the entrance of the unloading plate 235, and is used to detect the head of the sheet 81. Specifically, the head of the sheet 81 is determined by detecting the material for the first time after the material is cut off. The clamping unit 232 is located downstream of the discharge detection sensor 231. When the discharge detection sensor 231 detects the sheet 81, the clamping units 232 on both sides are activated to clamp the sheet 81. Then the conveying chain 22 moves to drive the sheet 81 to move toward the sheet pressing mechanism. During the movement, the sheet 81 is always suspended on the water of the second buffer pool 21. While cleaning the surface of the sheet 81, it also overcomes the influence of gravity, which is convenient for the transportation of the sheet 81.

[0102] like Fig.11 As shown, the material break detection sensor 234 is located at the feeding end of the sheet pressing mechanism, and the crimping unit 233 is located between the sheet pressing mechanism and the material break detection sensor 234. When the material break detection sensor 234 detects a material break, the pressing roller 3 of the sheet pressing mechanism stops running, and the tail of the previous sheet 81 stops in front of the pressing roller 3. At this time, the clamping unit 232 clamps a new sheet 81 to the material break detection sensor 234, and the clamping unit 232 releases the sheet 81. The clamping unit 232 moves in a circular motion and resets. The sheet 81 falls naturally and overlaps with the tail of the previous sheet 81. Then the crimping unit 233 operates to crimp the overlapping parts of the two sheets 81. The sheets 81 are connected together under pressure to form a continuous sheet. After the crimping is completed, the pressing roller 3 starts working to carry out the subsequent sheet pressing process. Specifically, the specific unloading position of the clamping unit 232 can be set so that the release position is as close to the crimping unit 233 as possible, or the broken material detection sensor 234 can be used to detect whether the sheet 81 has reached the crimping station, so that the rear clamping unit 232 delays the release of the sheet 81 to ensure that the front and rear sheets 81 always have overlapping parts.

[0103] Specifically, Fig.12 As shown, the clamping unit includes: a clamping motor 2321, a fixed finger 2322, a movable finger 2323 and a mounting seat 2324. The clamping unit is installed on the chain of the conveying chain 22 through the mounting seat 2324. The fixed finger 2322 is fixedly connected to the mounting seat 2324. The movable finger 2323 is hinged at the connection between the fixed finger 2322 and the mounting seat 2324, and its end is an arc-shaped tooth. The output end of the clamping motor 2321 is meshed with the arc-shaped tooth through a gear, and the movable finger 2323 is driven to rotate by the clamping motor 2321, thereby realizing the opening and closing of the clamping unit. When the discharge detection sensor 231 detects the head of the sheet 81, the clamping motor 2321 drives the movable finger 2323 to rotate and close, and clamps the head of the sheet 81 together with the fixed finger 2322. After arriving at the crimping station, the clamping motor 2321 reverses, opens the movable finger 2323, and releases the sheet 81.

[0104] like Fig.11As shown, the crimping unit 233 includes: a cylinder 2331 and a pressing plate 2332a. The output end of the cylinder 2331 is fixedly connected to the pressing plate 2332a. The piston of the cylinder 2331 is extended and retracted to drive the pressing plate 2332a to be pressed down, thereby realizing the crimping of the overlapping parts of the two sheets 81.

[0105] The tablet pressing mechanism is composed of a multi-stage pressing roller, and a conveying water pool is arranged between the multi-stage pressing rollers. There is water flowing from upstream to downstream in the conveying water pool, which is used to convey the tablets downstream and wash the tablets with water.

[0106] During the tableting process, water flow is used to transport and wash the acid, which achieves simultaneous acid washing during tableting and effectively improves production efficiency.

[0107] Furthermore, if Fig.13 As shown, the film hanging rod device 5 is connected to the sheet pressing mechanism through the conveyor belt 4 to realize automatic cutting, automatic hanging and automatic rod unloading of the incoming material (continuous film 81), and the automatic hanging rack device 6 realizes the shelving of the hanging rod 7 full of film 82 for subsequent drying.

[0108] Specifically, Figure 14-15 As shown, the film hanging rod device 5 includes: a swing-in cutting mechanism 53, a hanging rod conveying mechanism and a rod output mechanism 52. The hanging rod conveying mechanism conveys the hanging rod 7 to the rod input station, the hanging rod station and the rod output station arranged in sequence along the width direction of the film 82 in a step-by-step manner. A rod input mechanism such as a robot can be set at the entrance end of the rod input station. When the hanging rod support arm 511 of the hanging rod conveying mechanism reaches the rod input position, the rod input mechanism puts a hanging rod 7 on the hanging rod support arm 511 to realize the supply of the hanging rod 7. The swing-in cutting mechanism 53 is arranged below the discharge port of the film conveyor belt 4. When the film 81 falls to a specified length, the swing-in cutting mechanism 53 is activated to cut the film 81 into films 82 of a specific length, and the films 82 are hung on the hanging rod 7 below. At this time, the hanging rod conveying mechanism is activated to convey the hanging rod 7 along the width direction of the films 82 by a hanging film placement distance, and a gap is left between two adjacent films 82 so that the subsequent rod discharging mechanism can clamp the rod. When a hanging rod 7 is hung with films 82 (in this embodiment, each hanging rod 7 hangs five films 82), the hanging rod 7 hung with films 82 completely enters the rod discharging station, and the rod discharging mechanism 52 is activated to transfer the hanging rod 7 to the automatic hanging rack device 6, and the automatic hanging rack device 6 performs the racking operation, thereby realizing the automatic cutting, automatic hanging racking and automatic racking of continuous films, greatly improving the production efficiency.

[0109] Specifically, the hanging rod conveying mechanism is a circular conveyor 51 with step-by-step motion, and a plurality of hanging rod support arms 511 are arranged at equal intervals on the conveying chain. The hanging rod support arms 511 extend outward from the circular conveyor 51, so that a space for the cut end of the film 82 to fall is formed between the hanging rod 7 and the circular conveyor 51. The two hanging rod support arms 511 support the two ends of the hanging rod 7 respectively, and the three connected hanging rod support arms 511 support two hanging rods 7 in total. The hanging rod support arms 511 make circular motion on the vertical plane with the conveying chain, so as to realize the recycling of the hanging rod support arms 511. At least one in-position detection sensor 525 is provided on the frame of the hanging rod conveying mechanism. When the in-position detection sensor 525 detects the hanging rod support arm 511, it means that the conveying chain has just moved the length of a hanging rod 7, and at this time, the rod discharging mechanism 52 is actuated to discharging the rod.

[0110] like Fig.16 As shown, the swing-in cutting mechanism 53 includes: a swing rod assembly and a cutter 533. The swing rod assembly includes a swing motor 531 and a swing rod 532. The swing motor 531 is located at the discharge port of the conveyor belt 4 and is connected to the swing rod 532 through a fixed shaft and a connecting plate. The swing rod 532 is arranged along the width direction of the film 81 and is located on the outside of the film 81. The swing motor 531 drives the swing rod 532 to swing inward, so that the film 81 moves toward the cutter 533 and is cut by the cutter 533 to cut into a film 82. The cut end of the film 82 moves to the inside of the hanging rod 7 under the action of the swing rod 532. After the film 82 naturally hangs down, it hangs on the hanging rod 7 to complete a film hanging action. It should be noted that the conveying speed of the hanging rod 7 matches the time required for half the length of the film 82 to fall to one side of the hanging rod 7, and the distance from the cutter 533 to the axis of the hanging rod is slightly larger than half the length of the film 82. The two sides of the same film 82 are symmetrically distributed with the hanging rod 7 as the axis as much as possible, and the two sides of the hanging rod 7 are the same length, which can improve the uniformity of drying and avoid the problem of different drying degrees on the two sides of the hanging rod 7 of the same film 82.

[0111] Further, the rod-out mechanism 52 comprises: a rod-out cylinder 521 and a rod-out arm 522, the rod-out cylinder 521 and the rod-out arm 522 are located inside the hanging rod 7, the rod-out arm 522 is connected to the output end of the rod-out cylinder 521, and a clamping arm 524 is arranged on the rod-out arm 522, and the clamping arm 524 is driven by the clamping cylinder 523 to clamp the hanging rod 7. Specifically, when the in-place detection sensor 525 detects the hanging rod support arm 511, the rod-out cylinder 521 is actuated for the first time, driving the rod-out arm 522 to move forward slightly, so that the clamping arm 524 partially extends to the interval between the two films 82, and then the clamping cylinder 523 is actuated to drive the clamping arm 524 to clamp the hanging rod 7, and then the rod-out cylinder 521 is actuated for the second time, moving the hanging rod 7 forward and sending it into the hanging rod finishing mechanism 614, waiting for the hanger, and the rod-out mechanism 52 is reset after releasing the hanging rod 7, waiting for the next rod-out operation.

[0112] The specific production process is as follows:

[0113] First, after the cylindrical gel 8 is sent into the first buffer pool 12, the mandrel 131 is manually removed from the circular feed chain 13, and the mandrel 131 is inserted into the center hole of the gel 8. Then, the mandrel 131 and the gel 8 are installed on the circular feed chain 13 together. The rotary cutting mechanism 11 transmits power to the circular feed chain 13 through the transmission assembly, driving the gel 8 to move forward with the mandrel 131, and the mandrel 131 moves clockwise with the circular feed chain 13, so that the gel 8 is transported at a low position. When the cylindrical gel 8 contacts the rear end belt roller 14, the gel 8 rotates around the mandrel 131 under the friction of the belt roller 14, and the rotary cutter of the rotary cutting mechanism 11 cuts the rotating gel 8. While cutting, the gel 8 continues to feed along the circular feed chain 13, thereby realizing continuous slicing of the cylindrical gel 8. After completing the rotary cutting of one roll of gel 8, the rotary cutting of the next gel 8 begins immediately, and the mandrel 131 reversely circulates along the circular feed chain 13 to return to the initial position.

[0114] After the sheet 81 cut from the cylindrical gel 8 is thrown out from the discharge end of the rotary cutting mechanism 11, it is detected by the discharge detection sensor 231 above, and the clamping motor 2321 drives the movable finger 2323 to rotate, and clamps the head of the sheet 81 together with the fixed finger 2322 (during this process, the discharge end of the rotary cutting mechanism 11 continues to discharge). After the clamping unit 232 moves forward to the crimping station, the clamping motor 2321 reverses, opens the movable finger 2323, releases the sheet 81, and the head of the sheet 81 falls naturally and overlaps with the tail of the previous sheet 81. During this process, the clamping unit 232 keeps moving. Then the cylinder 2331 moves, driving the pressing plate 2332a to press down the overlapping parts of the two sheets 81, connecting the two sheets 81 together, thereby forming a continuous sheet. After the cylinder 2331 is reset, the downstream pressure roller 3 starts, drives the sheet 81 to move, and realizes the sheet pressing process.

[0115] After being pressed, the finished film 81 is continuously delivered to the discharge point of the conveyor belt 4 through the conveyor belt 4. While the finished film 81 is continuously delivered and dropped from the discharge end, the ring conveyor 511 located on the inner side below the finished film 81 delivers the hanging rod 7 a hanging film placement distance along the width direction of the finished film 81. The delivery speed of the hanging rod 7 matches the time required for the film 82 of half the required length to fall to one side of the hanging rod 7. When the hanging rod 7 is in place, the swing motor 531 drives the swing rod 532 to swing, swinging the finished film 81 toward the cutter. After the finished film 81 is cut by the cutter, the cut end naturally drops and hangs symmetrically on the hanging rod 7 to complete a hanging film action. Then the swing rod 532 quickly resets, and the ring conveyor 511 moves another hanging film placement distance, repeating the above actions, realizing the function of hanging multiple hanging films on one hanging rod 7 at intervals.

[0116] like Fig.17As shown, the automatic hanging rack device 6 includes: a hanging rack 63, a hanging rod arrangement mechanism 614 and a rod moving mechanism 62. The hanging rack 63 is a C-shaped structure with one end open. It is provided with several layers. On each layer, several second supporting arms 631 are arranged at equal intervals. Two opposite second supporting arms 631 respectively support the two ends of the hanging rod 7. The hanging rod arrangement mechanism 614 is located at the open end of the hanging rack 63. It is composed of a chain conveyor 611 and several first supporting arms 612 arranged thereon. Two opposite first supporting arms 612 respectively support the two ends of the hanging rod 7. The inlet end of the chain conveyor 611 is directly opposite to the discharging station of the film hanging rod device 5. The discharging mechanism 52 moves the hanging rod 7 forward to the first group of first supporting arms 612 placed at the inlet end of the chain conveyor 611. Then, the chain conveyor 611 moves once to move the hanging rod 7 toward the hanging rack 63 by one position. The chain conveyor 611 performs cyclic stepping motion at equal intervals, and utilizes the first supporting arms 612 at equal intervals to achieve uniform arrangement of the hanging rods 7 so that the subsequent rod shifting mechanism 62 can grab and put them on the shelves.

[0117] Furthermore, if Figure 18-21 As shown, the rod moving mechanism 62 includes: a gantry 621 and a grabbing manipulator 622. The grabbing manipulator 622 is installed on the gantry 621 through a lateral movement unit 624 and a lifting unit 625. The lateral movement unit 624 is used to realize the lateral movement of the grabbing manipulator 622 from the discharge end of the chain conveyor 611 to the corresponding position of the hanger 63, and the lifting unit 625 is used to realize the lifting and lowering of the grabbing manipulator 622. The grabbing manipulator 622 is provided with a plurality of through holes larger than the diameter of the end of the hanging rod 7 on the clamping plate 623 driven by a hydraulic cylinder. The hydraulic cylinder drives the two clamping plates 623 to approach each other, and the hanging rod 7 is inserted into the corresponding through hole, so that multiple hanging rods 7 can be moved simultaneously.

[0118] Example 2

[0119] like Fig. 22 As shown, in the present embodiment, a water spray assembly is provided at the inlet end of the blanking plate 235 of the overlapping mechanism 2, and the water spray assembly is composed of a pump 236 and a water outlet pipe. The pump 236 pumps the water in the second buffer pool 21 to the water outlet pipe provided at the inlet end of the blanking plate 235, and then flows out from the water outlet pipe, so that a water flow 237 is formed on the surface of the blanking plate 235. The water flow 237 mainly serves to reduce the friction between the sheet 81 and the blanking plate 235, and at the same time gives a force to the sheet 81 to accelerate the movement of the head of the sheet 81, avoid the head of the sheet 81 being retained, and cause the rear end to be clamped by the clamping unit 232, so as to improve the accuracy of the subsequent overlapping process.

[0120] In addition, corresponding nozzles may be provided at the discharge roller of the rotary cutting mechanism 11 and the pressing roller of the sheet pressing mechanism to spray water to the sheets passing through these places, so as to keep a layer of water film on the surface of the sheets at all times and reduce adhesion.

[0121] Example 3

[0122] like Figure 23-25 As shown, in this embodiment, the crimping member of the overlap mechanism 2 adopts an articulated crimping roller 2332b, which is driven by a cylinder 2331. Specifically, a support 2333b is provided at the output end of the cylinder 2331, and the support 2333b extends toward the side of the material break detection sensor 234. The crimping roller 2332b is articulated with the support 2333b through a connecting member 2335b. The articulation can be set relatively tight, but it does not affect its rotation, so that the crimping roller 2332b is kept pressed down into a sheet 81 without affecting its rotation. A limit block 2334b is provided on the support 2333b. The limit block 2334b is located at one end of the support 2333b close to the material break detection sensor 234, and is used to limit the connection member 2335b from rotating toward the side close to the material break detection sensor 234. When the overlapping parts of the two sheets 81 are pressed down, the piston of the cylinder 2331 extends, driving the support 2333b and the crimping roller 2332b to descend, and the crimping roller 2332b squeezes the overlapping parts of the two sheets 81. As the piston continues to extend, the connecting piece 2335b gradually rotates around the hinge, causing the crimping roller 2332b to roll the overlapping sheets 81 backwards, increasing the crimping area, and avoiding the connection between the two sheets 81 being detached when the crimping roller 3 is started due to insufficient crimping.

[0123] Example 3

[0124] like Fig.26 As shown, in this embodiment, the hanging rack 63 is formed by stacking several layers of plug-in pallets 632, and each layer of plug-in pallets 632 is provided with several second supporting arms 631. After each layer of hanging rods 7 is put on the rack, another layer of plug-in pallets 632 is stacked on top. The height of the hanging rack 63 can be adjusted according to actual conditions.
