Description

Technical Field

[0001] This invention relates to the field of smoked sheet adhesive production technology, specifically to a smoked sheet adhesive production system and process. Background Technology

[0002] Smoked sheet rubber is a natural rubber commodity, and its current production process is as follows:

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

[0004] (2) Coagulation: After filtering out impurities, the latex is diluted with water and then acid is added for coagulation treatment, so that the latex coagulates into a block.

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

[0006] (4) Smoking and drying: The compressed film is smoked and dried. This step is a key step in the production of smoked sheet adhesive. Smoking not only gives the film a unique smoky odor, but also improves its anti-aging and anti-corrosion properties.

[0007] (5) Packaging: The smoked and dried sheet adhesive will be packaged.

[0008] Current production equipment requires a large amount of manual labor in processes such as slicing, pressing, and film mounting, and cannot achieve continuous production. Summary of the Invention

[0009] To address the aforementioned problems, this invention provides a smoked sheet adhesive production system and process that enables automated and continuous production of high-quality smoked sheet adhesive, significantly reducing labor input, improving production efficiency, and ensuring the quality and consistency of the adhesive sheets.

[0010] Specifically, the present invention is implemented as follows:

[0011] A smoked sheet rubber production system includes: a filling section, a preparation section, a loading and unloading section, and a drying section, wherein the filling section is used to add acid to fill the latex so that it solidifies to form a cylindrical gel;

[0012] The preparation segment is equipped with a film preparation device, which includes:

[0013] A cylindrical gel cutting device is used to cut cylindrical gels into sheets;

[0014] The tableting mechanism, connected to the overlapping mechanism, is used to compress tablets.

[0015] The film hanging rod equipment is connected to the pressing mechanism via a conveyor belt. It is used to continuously cut the sheets from the pressing mechanism into film and hang the film on the hanging rod.

[0016] The loading and unloading section is equipped with an automatic hanging frame device, which is connected to the film hanging rod device to move the hanging rod full of film onto the hanging frame.

[0017] The rack containing the film is moved to the drying section for drying, eventually forming smoked sheet adhesive.

[0018] Furthermore, the cylindrical gel cutting device includes:

[0019] A feeding mechanism for conveying cylindrical gels;

[0020] A rotary cutting mechanism is used to cut cylindrical gels into sheets;

[0021] The first buffer pool contains a cleaning solution used to clean the acid from the surface of the cylindrical gel.

[0022] The feed roller, located above the rotary cutting mechanism, contacts the cylindrical gel during cutting and drives it to rotate. The surface of the feed roller can be patterned, with the pattern pointing in the direction of the rotary cutting blade's movement. This pattern is used to counteract the force exerted on the gel by the rotary cutting blade's movement, thus solving the problems of sheet misalignment and uneven thickness.

[0023] The feeding mechanism includes:

[0024] An annular feed chain is provided with at least one detachable mandrel, which passes through a cylindrical gel and is used to mount the cylindrical gel on the annular feed chain so that it can move along the conveying direction of the annular feed chain; during feeding, the mandrel is located in a cleaning solution so that the cylindrical gel is immersed in the cleaning solution;

[0025] The transmission assembly is connected to the rotary cutting mechanism and the annular feed chain respectively, and is used to transmit the power of the rotary cutting mechanism to the annular feed chain to drive the annular feed chain to move towards the rotary cutting blade of the rotary cutting mechanism; the rotary cutting speed of the rotary cutting mechanism is adapted to the feeding speed of the annular feed chain.

[0026] Furthermore, the fragment is also equipped with an overlapping mechanism, which is located downstream of the cylindrical gel cutting device. The overlapping mechanism is used to overlap the sheets formed by cutting two continuous cylindrical gels together to form a continuous sheet.

[0027] The overlapping mechanism includes:

[0028] A discharge detection sensor is installed at the discharge point of the rotary cutting mechanism to detect the sheet head formed by cutting cylindrical gel.

[0029] A clamping unit is located at the discharge point of the rotary cutting mechanism and is used to clamp the tablet head formed by cutting cylindrical gel. The clamping unit is configured to move from the discharge point of the rotary cutting mechanism to the feed point of the downstream tableting mechanism. When the discharge detection sensor detects the tablet head, the clamping unit is activated, clamping the tablet head and driving it to move towards the feed point of the tableting mechanism.

[0030] A material breakage detection sensor is installed at the feeding point of the tableting mechanism to detect whether there is a material breakage. When the material breakage detection sensor detects a material breakage, the tableting mechanism stops running and waits for the overlap to be completed. The material breakage detection sensor is also used for the tablet head that is clamped by the clamping unit.

[0031] The pressing unit is located on the side of the material breakage detection sensor near the tablet pressing mechanism;

[0032] When the material breakage detection sensor detects the head of the sheet, the clamping unit releases the head of the sheet, and the head of the sheet falls naturally, overlapping with the tail of the previous sheet. The pressing unit then presses the overlapping part to make the two sheets overlap.

[0033] Furthermore, the discharge end of the rotary cutting mechanism is connected to an inclined downward feeding plate, and the discharge end of the feeding plate is provided with a second buffer pool containing a cleaning solution.

[0034] The clamping unit is located at the discharge end of the feeding plate. When the clamping unit moves the sheet head, the sheet is immersed in the cleaning solution.

[0035] Furthermore, a water spraying assembly is provided at the upper end of the feeding plate. The water spraying assembly is used to spray water onto the feeding plate so that a water flow is formed on the feeding plate and the entire plate comes into contact with the water flow.

[0036] Furthermore, the crimping unit includes:

[0037] Drive components;

[0038] The pressing component is hinged to the output end of the driving component. During pressing, the driving component drives the pressing component to press down.

[0039] A limiting member is provided at the hinge between the pressing member and the driving member, and is used to make the pressing member tilt in the direction of the pressing mechanism.

[0040] Furthermore, the film hanging pole device includes:

[0041] Placed under the conveyor belt, the cutting mechanism is used to cut continuous sheets into film.

[0042] A rod conveying mechanism is located below the swing-in cutting mechanism. The rod conveying mechanism includes a rod feeding station, a rod hanging station, and a rod exiting station arranged in sequence. The rod conveying mechanism is used to continuously convey rods so that they pass through the rod feeding station, the rod hanging station, and the rod exiting station in sequence.

[0043] The cutting mechanism is located above the hanging rod station. The sheet naturally falls to one side of the hanging rod, and then the cutting mechanism cuts the sheet into a film. The cut end of the film naturally falls to the other side of the hanging rod, and the film is hung on the hanging rod to complete one hanging action.

[0044] Furthermore, the insert cutting mechanism includes:

[0045] The swing assembly is located below the sheet conveyor belt and on either side of the sheet, and is used to drive the sheet to swing to the other side;

[0046] A cutter is positioned opposite to the swing assembly. The swing assembly drives the sheet to swing, and the cutter cuts it into pieces. The cut ends naturally hang down to the opposite side of the sheet's natural hanging side, and the sheet is hung on the hanging rod to complete one hanging action.

[0047] Furthermore, the rod-out station is equipped with a rod-out mechanism, which is used to feed the rods with film hanging on them into the loading and unloading section.

[0048] Furthermore, the loading and unloading section is equipped with a hanging frame, a hanging rod organizing mechanism, and a rod moving mechanism. The rod extending mechanism is connected to the hanging rod organizing mechanism, and the hanging rod fully covered with film is moved from the rod extending mechanism to the hanging rod organizing mechanism.

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

[0050] Furthermore, the tablet pressing mechanism consists of multiple stages of pressure rollers, with a conveying water tank between the stages of pressure rollers. The conveying water tank contains water flowing from upstream to downstream, which is used to convey the tablets downstream and to wash and acidify the tablets with water.

[0051] The present invention also provides a process for producing smoked sheet adhesive based on the above-mentioned smoked sheet adhesive production equipment, comprising:

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

[0053] The latex purification process is as follows: Fresh latex entering the factory is collected in a collection tank; after filtration, the fresh latex flows into a mixing tank; in the mixing tank, a dry content analyzer and a pH analyzer are used to automatically and online detect the dry content and ammonia content of the fresh latex. After the detection is completed, the relevant data is uploaded, and finally, the dry content of the fresh latex is automatically adjusted by the dry content adjustment system. When the latex in the mixing tank meets the production process requirements, the latex is pumped to the buffer tank of the filling machine, and together with the acid addition system, the latex and acid are quantitatively injected into the gelation tank. After automatic stirring, foaming, and capping, a robotic arm places multiple gelation tanks onto a tray. After the stacking of a gelation tank is completed, an electric pallet jack transports it to the coagulation warehouse for the gelation process.

[0054] Film preparation steps: The solidified cylindrical gel is transferred to a cylindrical gel cutting device, where it is cut into sheets. These sheets are then pressed by a pressing mechanism and conveyed to a film hanging device for cutting and hanging. During the film preparation process, a cleaning solution is used between each step for conveying and washing the sheets. The specific film preparation process is as follows:

[0055] An electric pallet jack moves the gel bucket, after it has met the gelation process requirements, to a cylindrical gel cutting device. The bucket is then tilted, and the cylindrical gel is poured into a first buffer tank. The water in the first buffer tank washes away the acid on the surface of the cylindrical gel. A mandrel is manually inserted into the center of the cylindrical gel, and then the rotary cutting mechanism 11 cuts it into sheets. The sheets are then pressed by a pressing mechanism and conveyed by a conveyor belt to a film hanging device. During pressing, water flowing from upstream to downstream in a water tank transports the sheets downstream and washes them with acid. The pressed sheets are then sent to the film hanging device, cut into films, and hung on the hanging rods. The hanging rods are used for multiple films, meaning multiple films are hung on the same rod.

[0056] Loading process: The automatic hanging device moves the hanging rod full of film onto the hanging rack;

[0057] Drying steps: Move the rack with the film to the drying section for drying. The drying process includes an initial fumigation stage, a constant-speed drying stage, and a falling-speed drying stage. The initial fumigation stage temperature is 48-50℃, and the drying time is 3-4 hours. The constant-speed drying stage temperature is 70-75℃, and the film moisture content is <10%. The falling-speed drying stage temperature is 70-75℃, and the drying time is 2-3 days, with a moisture content <0.5%.

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

[0059] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0060] (1) This invention realizes the automated and continuous production of latex into smoked sheet adhesive, greatly reducing manual input, improving production efficiency, and ensuring the quality and consistency of the film.

[0061] (2) It ensures the uniformity of the slice thickness. At the same time, the connecting mechanism connects the two sheets to form a continuous sheet, so that the film with the same length can be obtained when it is placed into the cutting mechanism, thus ensuring that the final product has a uniform and consistent appearance.

[0062] (3) The automatic racking equipment's racking mechanism realizes the centralized and regular arrangement of the racks, and then uses the racking mechanism to move the racks to the rack, thereby realizing the automatic racking of tobacco sheet adhesive, achieving the purpose of replacing manual operation, and meeting the requirements of efficient and reliable automated production.

Detailed Implementation

[0091] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0092] Example 1

[0093] like Figure 1-2As shown, this invention provides a smoked sheet rubber production system, including: a pretreatment section, a filling section, a segmentation section, a loading and unloading section, and a drying section. The pretreatment section is equipped with a collection tank and a summarization tank. Fresh latex entering the plant is uniformly collected in the collection tank. After filtration, the fresh latex flows into a mixing tank. In the mixing tank, a dry content analyzer and a pH analyzer are used to automatically and online detect the dry content and ammonia content of the fresh latex. After the detection is completed, the relevant data is uploaded. Finally, the dry content of the fresh latex is adjusted by the dry content adjustment system to meet the production requirements. After adjustment, the latex is pumped to the filling machine buffer tank in the filling section, and together with the acid addition system, the latex and acid are quantitatively injected into the gel buckets. After automatic stirring, foaming, and capping, a robot arm places multiple gel buckets onto a tray, which is then transported by AGV to the coagulation chamber for coagulation. The solidified cylindrical gel is transferred, capped, and fed into the film preparation section. After being cut into sheets, overlapped, pressed, and trimmed, the sheets are hung on long hanging rods 7 in a sheet-like manner. They are then fed into the loading and unloading section, where an automatic hanging device 6 moves the hanging rods 7, now filled with film sheets, to hanging racks 63. The hanging racks 63, now containing film sheets 82, are then moved to the drying section for drying. The drying process includes an initial fumigation stage, a constant-rate drying stage, and a decreasing-rate drying stage. The initial fumigation stage temperature is 48-50℃, and the drying time is 3-4 hours. The constant-rate drying stage temperature is 70-75℃, and the film moisture content is <10%. The decreasing-rate drying stage temperature is 70-75℃, and the drying time is 2-3 days, with a moisture content <0.5%. After drying, the film is transferred out of the warehouse for testing and grading, and then packaged according to its grade.

[0094] Specifically, such as Figure 3As shown, the film preparation equipment includes: a cylindrical gel cutting device 1, an overlapping mechanism 2, a pressing mechanism 3, and a film hanging device 5. The cylindrical gel cutting device 1 includes a feeding mechanism, a rotary cutting mechanism 11, a first buffer pool 12, and a conveyor 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 buoyed and suspended on the water, which facilitates the movement of the gel 8 and the subsequent installation of the mandrel 131. At the same time, the water in the first buffer pool 12 will clean the acid on the surface of the gel, achieving the purpose of acid washing. The feeding roller 14 is located above the rotary cutting mechanism 11. The feeding mechanism delivers the gel 8 to the feeding roller 14 and the rotary cutting mechanism 11. The gel 8 contacts the feeding roller 14, and the rotation of the feeding roller 14 drives the gel 8 to rotate around the mandrel 131. At the same time, the rotary cutting blade of the rotary cutting mechanism 11 cuts the rotating gel 8. While cutting, the gel 8 continues to be fed, thereby realizing continuous slicing of 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 pressure roller 3. It is mainly used for acid washing of the sheets formed by rotary cutting and for buffering and providing buoyancy to facilitate the overlapping and conveying of two sheets. After being pressed by the pressure roller 3, a continuous sheet is formed.

[0095] Specifically, such as Figure 4-6 As shown, the feeding mechanism includes an annular feed chain 13 and a transmission assembly. The annular feed chain 13 consists of two chains and several sprockets. The two chains are driven by a first transmission shaft 133 to achieve synchronization. Several detachable spindles 131 are set between the two chains. In this embodiment, the spindles 131 are connected to the chains at both ends by snap-fitting. That is, a slot is set on the chain, and then the two ends of the spindle 131 are snapped into the two slots respectively to realize the installation of the spindle 131, so that the spindle 131 moves with the annular feed chain 13. It should be noted that the lower position of the chain should be below the water surface of the first buffer pool 12, so that the spindle 131 is immersed in water when conveyed at the lower position, and so that the gel 8 on it is immersed in water as much as possible to ensure the acid washing effect.

[0096] One end of the first drive shaft 133 is a manual feed wheel 132, and the other end is connected to the power shaft of the rotary cutting mechanism 11 via a transmission assembly. This allows the power of the rotary cutting mechanism 11 to be introduced into the annular feed chain 13, driving the annular feed chain 13 to automatically feed, thus achieving automatic feeding of the gel 8. The feeding speed of the gel 8 is adapted to the rotary cutting mechanism 11 to ensure uniform thickness of the cut sheets. Specifically, the transmission assembly includes a second drive shaft 134. One end of the second drive shaft 134 is connected to the power shaft of the rotary cutting mechanism 11 via a gear, and the other end is connected to the first drive shaft 133 via a sprocket and chain. A clutch 135 is provided on the second drive shaft 134 to cut off the power, allowing manual rotation of the manual feed wheel 132 in special circumstances to manually feed the gel 8. In this embodiment, the basic parameters of the rotary cutting mechanism 11 are shown in Table 1.

[0097] Table 1

[0098] power Approximately 4kW Applicable gel size (cylindrical) ≤Φ800X500 Rotary cutting speed Approximately 680 m / h Gel processing capability Approximately 6200 kg / h Rotary cutting of a tube of gel time Approximately 30 seconds Slice thickness (adjustable) 20±5mm

[0099] Furthermore, during the rotary cutting process, the rotating blade exerts a lateral force on the gel 8, causing the cut sheet to shift position. Simultaneously, the elasticity of the gel 8 leads to uneven sheet thickness, even with significant differences in thickness between the left and right sides of the same sheet. Therefore, the material roller 14 of this invention features a pattern on its upper surface, oriented towards the direction of the rotary cutting blade's movement. This pattern provides a counterforce to the gel 8, counteracting the force exerted by the rotary cutting blade and effectively solving the problems of sheet shift and uneven thickness.

[0100] like Figure 7 As shown, the overlapping mechanism includes: a discharge detection sensor 231, a clamping unit 232, a material breakage detection sensor 234, and a pressing unit 233. The clamping unit 232 is conveyed in a ring by a conveyor chain 22. Two opposing clamping units 232 are located on both sides of the sheet 81, jointly clamping the head of the sheet 81. Figure 8-10 As shown, due to the high speed of the upstream rotary cutting, the sheet 81 is thrown out when it leaves the conveyor roller. In order to facilitate the subsequent clamping unit 232 to clamp the sheet, the present invention has an inclined downward feeding plate 235 connected at the discharge point of the rotary cutting mechanism 11. The feeding plate 235 is used to receive the thrown sheet 81 and play a guiding role, thereby ensuring that the clamping unit 232 can accurately clamp the sheet 81.

[0101] The discharge detection sensor 231 is located at the inlet of the feed plate 235 and is used to detect the head of the sheet 81. Specifically, it is determined by the first detection of material 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 conveyor chain 22 moves, driving the sheet 81 to move towards the tableting mechanism. During the movement, the sheet 81 is always suspended on the water in the second buffer pool 21, which cleans the surface of the sheet 81 and overcomes the influence of gravity, facilitating the conveying of the sheet 81.

[0102] like Figure 11 As shown, the material breakage detection sensor 234 is located at the feeding end of the tableting mechanism, and the pressing unit 233 is located between the tableting mechanism and the material breakage detection sensor 234. When the material breakage detection sensor 234 detects a material breakage, the pressure roller 3 of the tableting mechanism stops running, causing the tail of the previous sheet 81 to stop in front of the pressure roller 3. At this time, the clamping unit 232 clamps a new sheet 81 to the material breakage detection sensor 234, the clamping unit 232 releases the sheet 81, the clamping unit 232 moves in a ring to reset, the sheet 81 falls naturally and overlaps with the tail of the previous sheet 81. Then the pressing unit 233 operates to press the overlapping part of the two sheets 81. The sheets 81 are joined together under pressure, thus forming a continuous sheet. After the pressing is completed, the pressure roller 3 starts to work and performs the subsequent tableting process. Specifically, the specific unloading position of the clamping unit 232 can be set so that the release position is as close as possible to the crimping unit 233, or the material breakage detection sensor 234 can detect whether the sheet 81 has reached the crimping station. After reaching the crimping station, the clamping unit 232 releases the sheet 81 after a delay to ensure that the two sheets 81 always have an overlapping part.

[0103] Specifically, such as Figure 12 As shown, the clamping unit includes a clamping motor 2321, a fixed finger 2322, a movable finger 2323, and a mounting base 2324. The entire clamping unit is mounted on the chain of the conveyor chain 22 via the mounting base 2324. The fixed finger 2322 is fixedly connected to the mounting base 2324. The movable finger 2323 is hinged at the connection between the fixed finger 2322 and the mounting base 2324, and its end is an arc-shaped tooth. The output end of the clamping motor 2321 meshes with the arc-shaped tooth through a gear, driving the movable finger 2323 to rotate, 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, clamping the head of the sheet 81 together with the fixed finger 2322. After reaching the pressing station, the clamping motor 2321 reverses, opens the movable finger 2323, and releases the sheet 81.

[0104] like Figure 11As shown, the crimping unit 233 includes a cylinder 2331 and a pressure plate 2332a. The output end of the cylinder 2331 is fixedly connected to the pressure plate 2332a. By extending and retracting the piston of the cylinder 2331, the pressure plate 2332a is driven to press down, thereby achieving the crimping of the overlapping part of the two sheets 81.

[0105] The tableting mechanism consists of multiple stages of pressure rollers, with a conveying water tank between them. The water tank contains water flowing from upstream to downstream, which is used to convey the tablets downstream and to wash and acidify the tablets with water.

[0106] During the film production process, water flow is used for both conveying and acid washing, which enables simultaneous acid washing during film production and effectively improves production efficiency.

[0107] Furthermore, such as Figure 13 As shown, the film hanging device 5 is connected to the pressing mechanism via the conveyor belt 4 to realize automatic cutting, automatic hanging and automatic discharging of the incoming material (continuous sheets 81). The automatic hanging device 6 realizes the mounting of the hanging rod 7 full of film sheets 82 for subsequent drying.

[0108] Specifically, such as Figure 14-15 As shown, the film hanging rod device 5 includes: a cutting mechanism 53, a hanging rod conveying mechanism, and a hanging rod dispensing mechanism 52. The hanging rod conveying mechanism conveys the hanging rods 7 sequentially along the width direction of the film 82 to the rod feeding station, hanging station, and dispensing station in a step-by-step manner. The entrance end of the rod feeding station can be equipped with a rod feeding mechanism such as a robot arm. When the hanging rod support arm 511 of the hanging rod conveying mechanism reaches the rod feeding position, the rod feeding mechanism places a hanging rod 7 on the hanging rod support arm 511 to realize the supply of hanging rods 7. The cutting mechanism 53 is located below the discharge port of the sheet conveyor belt 4. When the sheet 81 falls to a specified length, the cutting mechanism 53 operates, cutting the sheet 81 into film sheets 82 of a specific length and hanging the film sheets 82 on the hanging rods 7 below. At this time, the hanging rod conveying mechanism operates, conveying the hanging rods 7 along the width direction of the film sheets 82 by a hanging sheet placement distance, leaving a gap between adjacent film sheets 82 so that the subsequent rod dispensing mechanism can clamp and dispensing the rods. When a hanging rod 7 is fully loaded with film sheets 82 (in this embodiment, each hanging rod 7 is loaded with five film sheets 82), the hanging rod 7 fully loaded with film sheets 82 completely enters the rod dispensing station. At this time, the rod dispensing mechanism 52 operates, transferring the hanging rods 7 to the automatic hanging device 6, which performs the racking operation, thereby realizing continuous automatic cutting, automatic racking, and automatic racking of sheet sheets, greatly improving production efficiency.

[0109] Specifically, the hanging rod conveying mechanism is a stepping circular conveyor 51, on which several hanging rod support arms 511 are arranged at equal intervals. The hanging rod support arms 511 extend outward from the circular conveyor 51, so that a space is formed between the hanging rod 7 and the circular conveyor 51 for the cut end of the film 82 to fall. Two hanging rod support arms 511 support the two ends of the hanging rod 7 respectively, and three connected hanging rod support arms 511 support two hanging rods 7 in total. The hanging rod support arms 511 move in a circular motion in a vertical plane with the conveyor chain, thereby realizing the cyclic use of the hanging rod support arms 511. The frame of the hanging rod conveying mechanism is equipped with at least one position detection sensor 525. When the position detection sensor 525 detects the hanging rod support arm 511, it means that the conveyor chain has just moved the length of one hanging rod 7. At this time, the rod dismounting mechanism 52 is activated to dismount the rod.

[0110] like Figure 16 As shown, the swing-in cutting mechanism 53 includes a swing arm assembly and a cutter 533. The swing arm assembly includes a swing motor 531 and a swing arm 532. The swing motor 531 is located at the discharge port of the conveyor belt 4 and is connected to the swing arm 532 through a fixed shaft and a connecting plate. The swing arm 532 is arranged along the width direction of the sheet 81 and is located on the outer side of the sheet 81. The swing motor 531 drives the swing arm 532 to swing inward, causing the sheet 81 to move toward the cutter 533 and be cut by the cutter 533 into film sheets 82. The cut end of the film sheet 82 moves to the inner side of the hanging rod 7 under the action of the swing arm 532, and the film sheet 82 hangs naturally on the hanging rod 7, completing one hanging action. It should be noted that the conveying speed of the hanging rod 7 is matched with the time required for half the length of the film 82 to fall to one side of the hanging rod 7. The distance from the cutter 533 to the axis of the hanging rod is slightly greater than half the length of the film 82. This is to make the two sides of the same film 82 symmetrically distributed with the hanging rod 7 as the axis, and the two sides of the hanging rod 7 have the same length. This can improve the uniformity of drying and avoid the problem of different drying degrees on the two sides of the same film 82.

[0111] Further, the rod extension mechanism 52 includes: a rod extension cylinder 521 and a rod extension arm 522. The rod extension cylinder 521 and the rod extension arm 522 are located inside the hanging rod 7. The rod extension arm 522 is connected to the output end of the rod extension cylinder 521. A clamping arm 524 is provided on the rod extension arm 522. The clamping arm 524 is driven by the clamping cylinder 523 and is used to clamp the hanging rod 7. Specifically, when the positioning detection sensor 525 detects the hanging rod support arm 511, the rod extension cylinder 521 actuates for the first time, causing the rod extension arm 522 to move forward slightly, so that the clamping arm 524 extends to the gap between the two film sheets 82. Then the clamping cylinder 523 actuates, causing the clamping arm 524 to clamp the hanging rod 7. Then the rod extension cylinder 521 actuates a second time, moving the hanging rod 7 forward and sending it into the hanging rod organizing mechanism 614 to wait for the hanging frame. After the rod extension mechanism 52 releases the hanging rod 7, it resets and waits for the next rod extension operation.

[0112] The specific production process is as follows:

[0113] First, the cylindrical gel 8 is fed into the first buffer pool 12. Then, the mandrel 131 is manually removed from the annular feed chain 13 and inserted into the central hole of the gel 8. The mandrel 131 and gel 8 are then mounted together on the annular feed chain 13. The rotary cutting mechanism 11 transmits power to the annular feed chain 13 via a transmission assembly, causing the gel 8 to move forward with the mandrel 131. The mandrel 131 moves clockwise with the annular feed chain 13, ensuring the gel 8 is conveyed at a low position. When the cylindrical gel 8 contacts the rear conveyor roller 14, the gel 8 rotates around the mandrel 131 under the friction of the conveyor roller 14. Simultaneously, the rotary cutting blade of the rotary cutting mechanism 11 cuts the rotating gel 8. While cutting, the gel 8 continues to feed along the annular feed chain 13, thus achieving continuous slicing of the cylindrical gel 8. After one tube of gel 8 is rotary-cut, the next gel 8 is immediately rotary-cut, while the mandrel 131 returns to its initial position in the reverse cycle along the annular feed chain 13.

[0114] After the sheet 81, cut from cylindrical gel 8, is ejected from the discharge end of the rotary cutting mechanism 11, it is detected by the discharge detection sensor 231 above. The clamping motor 2321 drives the movable finger 2323 to rotate, which, together with the fixed finger 2322, clamps the head of the sheet 81 (during this process, the discharge end of the rotary cutting mechanism 11 continues to discharge). After the clamping unit 232 moves forward to the pressing station, the clamping motor 2321 reverses, opens the movable finger 2323, releases the sheet 81, and the head of the sheet 81 falls naturally, overlapping with the tail of the previous sheet 81. During this process, the clamping unit 232 continues to move. Then, the cylinder 2331 actuates, driving the pressure plate 2332a to press down the overlapping part of the two sheets 81, joining the two sheets 81 together to form a continuous sheet. After the cylinder 2331 resets, the downstream pressure roller 3 starts, driving the sheet 81 to move and realizing the tableting process.

[0115] After being pressed, sheet 81 is continuously conveyed to the discharge point of conveyor belt 4. As sheet 81 is continuously output and hangs down from the discharge end, the circular conveyor 511, located inside sheet 81, conveys the hanging rod 7 along the width direction of sheet 81 for a hanging piece placement distance. The conveying speed of the hanging rod 7 matches the time required for half the required length of film 82 to hang down to one side of the hanging rod 7. Simultaneously with the hanging rod 7 in place, the swing motor 531 drives the swing rod 532 to swing, swinging sheet 81 towards the cutter. After sheet 81 is cut by the cutter, the cut end naturally hangs symmetrically on the hanging rod 7, completing one hanging piece action. Then, the swing rod 532 quickly returns to its original position, and the circular conveyor 511 moves another hanging piece placement distance, repeating the above actions to achieve the function of hanging multiple pieces at intervals on one hanging rod 7.

[0116] like Figure 17As shown, the automatic hanging rack device 6 includes a hanging rack 63, a hanging rod organizing mechanism 614, and a rod moving mechanism 62. The hanging rack 63 is a C-shaped structure with one open end, and it has several layers. Each layer has several second support arms 631 at equal intervals, and two opposing second support arms 631 support the two ends of the hanging rod 7 respectively. The hanging rod organizing mechanism 614 is located at the open end of the hanging rack 63. It consists of a chain conveyor 611 and several first support arms 612 set on it. Two opposing first support arms 612 support the two ends of the hanging rod 7 respectively. The inlet end of the chain conveyor 611 is directly opposite the discharge station of the film hanging rod device 5. The rod discharging mechanism 52 moves the hanging rod 7 forward and places it on the first set of first support arms 612 at the inlet end of the chain conveyor 611. Then, the chain conveyor 611 moves once, moving the hanging rod 7 one position towards the hanging rack 63. The chain conveyor 611 performs cyclic stepping motion at equal intervals. By utilizing the first support arm 612 at equal intervals, the hanging rods 7 can be evenly arranged so that the subsequent rod shifting mechanism 62 can grab and place them on the frame.

[0117] Furthermore, such as Figure 18-21 As shown, the lever-shifting mechanism 62 includes a gantry 621 and a gripping robot 622. The gripping robot 622 is mounted on the gantry 621 via a lateral movement unit 624 and a lifting unit 625. The lateral movement unit 624 is used to move the gripping robot 622 laterally from the discharge end of the chain conveyor 611 to the corresponding position on the hanger 63. The lifting unit 625 is used to lift the gripping robot 622. The gripping robot 622 has hydraulically driven clamping plates 623 on both sides. Several through holes larger than the diameter of the end of the hanging rod 7 are provided on the clamping plates 623. The hydraulic cylinder drives the two clamping plates 623 to move closer together, and the hanging rod 7 is inserted into the corresponding through holes, enabling the simultaneous movement of multiple hanging rods 7.

[0118] Example 2

[0119] like Figure 22 As shown, in this embodiment, a water spraying assembly is provided at the inlet end of the unloading plate 235 of the overlapping mechanism 2. The water spraying assembly consists of a pump 236 and a water outlet pipe. The pump 236 pumps water from the second buffer pool 21 to the water outlet pipe at the inlet end of the unloading plate 235, and then the water flows out from the water outlet pipe, so that water flow 237 is formed on the surface of the unloading plate 235. The water flow 237 mainly reduces the friction between the sheet 81 and the unloading plate 235, and at the same time applies a force to the sheet 81 to accelerate the movement of the head of the sheet 81, so as to avoid the head of the sheet 81 from being stuck and causing the rear end to be clamped by the clamping unit 232, thereby improving the accuracy of the subsequent overlapping process.

[0120] In addition, corresponding nozzles can be installed at the discharge roller of the rotary cutting mechanism 11 and the pressure roller of the pressing mechanism to spray water onto the sheets passing through these areas, so as to keep the surface of the sheets always covered with a layer of water film and reduce adhesion.

[0121] Example 3

[0122] like Figure 23-25 As shown, in this embodiment, the pressing component of the overlapping mechanism 2 is a hinged pressing roller 2332b, which is driven by a cylinder 2331. Specifically, the output end of the cylinder 2331 is provided with a support 2333b, which extends towards the side of the material breakage detection sensor 234. The pressing roller 2332b is hinged to the support 2333b through a connector 2335b. The hinge can be set relatively tight, but it does not affect its rotation, so that the pressing roller 2332b can keep pressing down the sheet 81 without affecting its rotation. A limiting block 2334b is provided on the support 2333b. The limiting block 2334b is located at the end of the support 2333b near the material breakage detection sensor 234, and is used to limit the rotation of the connector 2335b towards the side near the material breakage detection sensor 234. When the two sheets 81 overlap, the piston of cylinder 2331 extends, driving the support 2333b and pressing roller 2332b to descend. The pressing roller 2332b squeezes the overlapping part of the two sheets 81. As the piston continues to extend, the connector 2335b gradually rotates around the hinge, causing the pressing roller 2332b to roll backward to press the overlapping sheets 81, increasing the pressing area and preventing the two sheets 81 from separating when the pressing roller 3 starts due to incomplete pressing.

[0123] Example 3

[0124] like Figure 26 As shown, in this embodiment, the hanging rack 63 is composed of several layers of plug-in trays 632 stacked together. Each layer of plug-in trays 632 is provided with several second support arms 631. After each layer of hanging rods 7 is installed, another layer of plug-in trays 632 is stacked on top. The height of the hanging rack 63 can be adjusted according to the actual situation.
