Description

Technical Field

[0001] This invention relates to the field of flame retardant processing equipment technology, specifically to a flame retardant multi-shape granulation equipment. Background Technology

[0002] Flame retardants are chemical substances used to slow down or prevent the combustion process of materials. They achieve this through various mechanisms, including inhibiting the combustion reaction, reducing the combustion rate, and minimizing flame spread. Flame retardants are commonly used in a variety of materials, such as plastics, textiles, wood, and electrical wires and cables, to improve their fire safety performance.

[0003] When flame retardant raw materials are extruded into flame retardant strips, they are first cooled in a cold water bath and then slit by a slitting device. Due to different customers requiring different sizes of flame retardant granules, changing the current granule size necessitates workers disassembling and replacing the mold body. This replacement process often presents the following drawbacks:

[0004] 1. Manual disassembly by workers is inefficient, and manual handling and docking are cumbersome.

[0005] 2. The mold head is very hot. If it is replaced immediately, it is easy to get burned. If you wait for it to cool down, it will take a long time.

[0006] 3. When the size of the output flame-retardant particles changes, the cooling time of flame-retardant strips of different sizes is different. Therefore, the main adjustment is currently the traction speed. However, adjusting the traction speed will affect the action speed of the cutting mechanism, making linkage adjustment inconvenient. At the same time, the stroke of the flame-retardant strip in the water tank remains unchanged, so the cooling adjustment effect is limited.

[0007] In summary, there is a need for a flame retardant multi-shape granulation equipment with high die replacement efficiency and high cooling efficiency. Summary of the Invention

[0008] To address the shortcomings of existing technologies, this invention provides a flame retardant multi-shape granulation device, which solves the problems mentioned in the background art.

[0009] To achieve the above objectives, the present invention provides the following technical solution:

[0010] A flame retardant multi-shape granulation device includes an extruder. A mold positioning assembly is installed at the outlet end of the extruder. A mold storage assembly is installed on the side of the mold positioning assembly. The mold storage assembly includes a support plate. A center plate is rotatably mounted on the top of the support plate. Multiple sets of second docking frames are provided on the side wall of the center plate. A set of mold frames can be detachably and slidably inserted into each second docking frame. A set of mold bodies is installed within each mold frame. The flame retardant strips produced by each set of mold bodies have different shapes. A cooling assembly is installed at the output end of the mold positioning assembly. The cooling assembly includes a cooling tank. A guiding assembly is installed inside the cooling tank. A transfer adjustment assembly is connected to the side of the guiding assembly. A slitting mechanism is installed at the output end of the cooling assembly.

[0011] The mold positioning assembly includes the following states:

[0012] In the first state, the mold body inside the mold positioning assembly is connected to the extruder outlet;

[0013] In the second state, the mold positioning assembly moves outward to dock with the empty second docking frame; the used mold body inside the mold positioning assembly disengages from the extruder; the mold positioning assembly transfers the used mold body into the empty second docking frame;

[0014] In the third state, the mold storage component drives the unused mold body to dock with the mold positioning component. The mold positioning component removes the unused mold body and its external mold frame. When the mold frame moves outward, it drives the transfer adjustment component to move. The transfer adjustment component adjusts the cooling and conveying path of the guide component to match the removed mold body, so as to ensure that the flame retardant strip can be fully cooled and output at high speed.

[0015] Furthermore, the mold positioning assembly includes a movable frame and a first docking frame. The first docking frame and the second docking frame have the same structure and are both U-shaped. The opening of the first docking frame faces the second docking frame. The movable frame is horizontally set and placed at the bottom of the output end of the extruder. The first docking frame is vertically slidably mounted on the surface of the movable frame. The mold frame is horizontally slidably inserted into the interior of the first docking frame. A first drive rod that drives the first docking frame in and out is installed inside the movable frame. A horizontally set second drive rod is installed at the bottom of the back of the first docking frame. The output end of the second drive rod is vertically connected to a movable rod. The top and bottom of the outer wall of the movable rod are vertically provided with first locking elements.

[0016] Furthermore, a back block is provided on the back side of the mold body, and the cross-sectional area of ​​the back block is smaller than the cross-sectional area of ​​the mold body.

[0017] The back block seal is inserted into the outlet end of the extruder. The mold body has a through discharge hole inside, and the mold body has symmetrical side positioning holes on both sides.

[0018] Furthermore, the mold frame includes a main frame, which is rectangular. The two ends of the main frame are symmetrically provided with movable positioning parts. The mold body is sealed and fitted into the main frame. The ends of the movable positioning parts are fitted into the side positioning holes. The end face of the mold frame near the center plate is provided with two sets of locking sleeves. A set of second locking parts is installed on the bottom and top of the outer wall of the second docking frame.

[0019] In the first state, the first docking frame is misaligned to the side of the second docking frame;

[0020] In the second state, the first docking frame moves forward once and docks with the second docking frame, and the openings of the first docking frame and the second docking frame are connected to each other; the first locking member extends outward to drive the used mold frame and the used mold body to transfer into the empty second docking frame; the first docking frame retracts, the first locking member disengages from the used mold frame, and the second locking member inserts into the used mold frame;

[0021] In the third state, the mold storage component drives the unused mold body to dock with the mold positioning component, the first docking frame moves forward twice to dock with the second docking frame, the first locking member is inserted into the unused mold frame, and the second locking member is pushed out of the unused mold frame; the first docking frame moves outward, which brings out the unused mold frame and its internal unused mold body.

[0022] Furthermore, the second locking component includes a positioning plate, one end of which is fixed to the outer wall of the second docking frame, and the other end of which is vertically slidably fitted with a third locking block. A first spring rod is installed between the outer end of the third locking block and the positioning plate, and the inner end of the third locking block has an arc-shaped structure facing the mold positioning assembly.

[0023] Furthermore, the first locking component includes a first locking block, which is vertically disposed on the outer wall of the movable rod. An L-shaped second locking block is vertically disposed on the side of the first locking block near the mold storage assembly. The outer ends of the first locking block and the second locking block are both arc-shaped structures facing the mold storage assembly. The first locking block is inserted into the locking sleeve, and the second locking block is used to pre-collide with the third locking block to retract.

[0024] Furthermore, each main frame has a set of linkage toothed plates at the bottom of its outer wall, and the length of each linkage toothed plate is different.

[0025] Furthermore, the transfer adjustment component includes a fixed block, which is fixed to the side wall of the cooling tank. A screw is installed inside the fixed block and rotates on its own. One end of the screw is provided with a driven gear, and the other end is threaded. A mating plate is fitted on the outside of the threaded end of the screw. A first constraint rod is provided at intervals at the bottom of the mating plate. The first constraint rod slides through the fixed block. Triangular blocks are fixedly connected to the ends of the first constraint rod and the mating plate. The triangular blocks are connected to the guide component. In the second state, when the mold frame has been moved, the rack meshes with the driven gear to drive the triangular blocks to retract and reset the guide component. In the third state, when the mold frame has not been moved, the rack meshes with the driven gear to drive the triangular blocks to advance and adjust the cooling guide path of the guide component.

[0026] Furthermore, the guiding assembly includes a first guide roller, a second guide roller, and a guiding control assembly. The guiding control assembly includes a lower linkage assembly and an upper linkage assembly. The first guide roller and the second guide roller are sequentially and spaced apart along the conveying direction inside the cooling tank. Both ends of the first guide roller and the second guide roller are vertically and elastically slidably installed in the guide side plate. Each second guide roller is located above the first guide roller. The extruded flame-retardant strip passes through the bottom surface of the first guide roller and the top surface of the second guide roller in sequence. Each group of first guide rollers is connected to the lower linkage assembly, and each group of second guide rollers is connected to the upper linkage assembly.

[0027] Furthermore, the upper linkage assembly includes an upper linkage crossbar, with multiple sets of first linkage vertical bars vertically spaced at the bottom surface of the upper linkage crossbar. The bottom end of each set of first linkage vertical bars is connected to a set of second guide rollers. An upper mating block is provided in the middle of the outer wall of the upper linkage crossbar. The lower linkage assembly includes a lower linkage crossbar, with multiple sets of second linkage vertical bars vertically spaced at the bottom surface of the lower linkage crossbar. The bottom end of each set of second linkage vertical bars is connected to a set of first guide rollers. A lower mating block is provided in the middle of the outer wall of the lower linkage crossbar. The top inclined surface of the triangular block contacts the upper mating block, and the bottom inclined surface contacts the lower mating block. When the triangular block is fed, it drives the upper and lower mating blocks to expand.

[0028] This invention provides a multi-shape granulation device for flame retardants. Compared with the prior art, it has the following advantages:

[0029] 1. The mold storage component can store various mold bodies. When it is necessary to change the size of the flame-retardant particles, the mold storage component can transfer the appropriate mold body to the mold positioning component to realize the automatic switching of the mold body.

[0030] 2. The design incorporates a movable mold positioning component. During normal operation, it connects to the outlet of the extruder, allowing the extruded material to be extruded through the mold within the mold positioning component, thus dispersing the flame-retardant strips. When replacement is required, the mold positioning component extends outward and connects to the mold storage component, enabling automatic removal of used mold bodies and automatic installation of unused mold bodies, eliminating the need for manual replacement and ensuring high replacement efficiency.

[0031] 3. The design incorporates a transfer adjustment component and a guide component. When the mold body moves horizontally, the transfer adjustment component is activated, and the guide component works in conjunction with it. This allows for a change in the cooling and conveying path of the guide component. When the mold body outputs large-diameter flame-retardant strips, the cooling conveying path is longer to ensure cooling effect and prevent insufficient cooling due to linear output. When the mold body outputs small-diameter flame-retardant strips, the cooling conveying path is shorter, ensuring both cooling effect and conveying speed. Attached Figure Description

[0049] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] Example 1

[0051] To address the technical problems in the background art, the following flame retardant multi-shape granulation equipment is provided:

[0052] Combination Figures 1-15 As shown, the present invention provides a flame retardant multi-shape granulation equipment, including an extruder 1. A mold positioning assembly is installed at the outlet end of the extruder 1, and a mold storage assembly 3 is installed on the side of the mold positioning assembly. The mold storage assembly 3 includes a support plate 31, and a center plate 32 is rotatably installed on the top of the support plate 31. The side wall of the center plate 32 is provided with multiple sets of second docking frames 33. A set of mold frames 4 can be detachably and slidably inserted into each second docking frame 33. A set of mold bodies 9 is installed in the mold frames 4. The flame retardant strips produced by each set of mold bodies 9 have different shapes.

[0053] A cooling component 5 is installed at the output end of the mold positioning component. The cooling component 5 includes a cooling tank 51. A guide component is installed inside the cooling tank 51. A transfer adjustment component 6 is connected to the side of the guide component. A cutting mechanism 8 is installed at the output end of the cooling component 5.

[0054] The mold positioning assembly includes the following states: In the first state, the mold body 9 inside the mold positioning assembly is connected to the extruder outlet; in the second state, the mold positioning assembly moves outward to connect with the empty second docking frame 33; the used mold body 9 inside the mold positioning assembly is disengaged from the extruder; the mold positioning assembly transfers the used mold body 9 into the empty second docking frame 33; in the third state, the mold storage assembly 3 drives the unused mold body 9 to connect with the mold positioning assembly, the mold positioning assembly removes the unused mold body 9 and its external mold frame 4, and when the mold frame 4 moves outward, it drives the transfer adjustment assembly 6 to operate. The transfer adjustment assembly 6 adjusts the cooling and conveying path of the guide assembly to match the removed mold body 9, so as to ensure that the flame retardant strip takes into account both sufficient cooling and high-speed output.

[0055] In the above scheme:

[0056] 1. The mold storage component can store various mold bodies. When it is necessary to change the size of the flame-retardant particles, the mold storage component can transfer the appropriate mold body to the mold positioning component to realize the automatic switching of the mold body.

[0057] 2. The design incorporates a movable mold positioning component. During normal operation, it connects to the outlet of the extruder, allowing the extruded material to be extruded through the mold within the mold positioning component, thus dispersing the flame-retardant strips. When replacement is required, the mold positioning component extends outward and connects to the mold storage component, enabling automatic removal of used mold bodies and automatic installation of unused mold bodies, eliminating the need for manual replacement and ensuring high replacement efficiency.

[0058] 3. The design incorporates a transfer adjustment component and a guide component. When the mold body moves horizontally, the transfer adjustment component is activated, and the guide component works in conjunction with it. This allows for a change in the cooling and conveying path of the guide component. When the mold body outputs large-diameter flame-retardant strips, the cooling conveying path is longer to ensure cooling effect and prevent insufficient cooling due to linear output. When the mold body outputs small-diameter flame-retardant strips, the cooling conveying path is shorter, ensuring both cooling effect and conveying speed.

[0059] In this embodiment, the mold positioning assembly 1 includes a movable frame 21 and a first docking frame 23. The first docking frame 23 and the second docking frame 23 have the same structure and are both U-shaped. The movable frame 21 is horizontally arranged and placed at the bottom of the output end of the extruder 1. The first docking frame 23 is vertically slidably installed on the surface of the movable frame 21. The mold frame 4 is horizontally slidably inserted into the interior of the first docking frame 23. The first drive rod 22 that drives the first docking frame 23 to move in and out is installed inside the movable frame 21. A horizontally arranged second drive rod 24 is installed at the bottom of the back side of the first docking frame 23. The output end of the second drive rod 24 is vertically connected to a movable rod 25. The top and bottom ends of the outer wall of the movable rod 25 are vertically provided with first locking members 26.

[0060] In the above scheme, during the forward and backward movement, the first drive rod drives the moving frame to move back and forth. During locking and unlocking, the second drive rod drives the movable rod to move horizontally, and the movable rod drives the two first locking parts to move horizontally.

[0061] The first locking component can achieve the following effects: 1. It can be inserted into the locking sleeve to position the mold frame and the mold body inside; 2. When the first locking component moves outward, it can pull the mold frame outward, realizing the automatic transfer of the mold frame and the mold body; 3. When it comes into contact with the second locking component, it can resist the second locking component from retracting, realizing the insertion and positioning of the first locking component; 4. When the first locking component retracts, the second locking component can be inserted accordingly.

[0062] The first and second docking frames are both U-shaped to facilitate the entry and exit of the mold frame and the mold body.

[0063] In this embodiment, a back block 93 is provided on the back side of the mold body 9. The cross-sectional area of ​​the back block 93 is smaller than that of the mold body 9. The back block 93 is sealed and inserted into the outlet end of the extruder 1. A through discharge hole 91 is provided inside the mold body 9. Side positioning holes 92 are symmetrically provided on both sides of the mold body 9.

[0064] In the above scheme, the back block can be inserted and positioned movably, and the size of the discharge hole of each mold body is different, thereby changing the discharge size of the flame retardant strip.

[0065] In this embodiment, the mold frame 4 includes a main frame 41, which is rectangular. Two movable positioning elements 42 are symmetrically arranged at both ends of the main frame 41. The mold body 9 is sealed and fitted into the main frame 41. The ends of the movable positioning elements 42 are fitted into the side positioning holes 92. Two sets of locking sleeves 43 are provided on the end face of the mold frame 4 near the center plate 32. A set of second locking elements 34 are installed on the bottom and top of the outer wall of the second docking frame 33. In the first state, the first docking frame 23 is misaligned to the side of the second docking frame 33. In the second state, the first docking frame 23 advances forward and docks with the second docking frame 33, and the opening of the first docking frame 23 is aligned with the opening of the second docking frame 33. The openings of 3 are relatively connected; the first locking member 26 extends outward to drive the used mold frame 4 and the used mold body 9 to transfer into the empty second docking frame 33; the first docking frame 23 retracts, the first locking member 26 disengages from the used mold frame 4, and the second locking member 34 inserts into the used mold frame 4; in the third state, the mold storage component 3 drives the unused mold body 9 to dock with the mold positioning component, the first docking frame 23 advances twice to dock with the second docking frame 33, the first locking member 26 inserts into the unused mold frame 4, and the second locking member 34 is pushed out of the unused mold frame 4; the first docking frame 23 moves outward, thus taking out the unused mold frame 4 and its internal unused mold body 9.

[0066] In the above scheme, the design of the mold frame can achieve the following effects:

[0067] 1. The movable positioning parts at both ends of the mold frame can be used to insert and position the mold body, making it easy to disassemble, clean and replace the mold body;

[0068] 2. The mold frame can move along the first docking frame and the second docking frame, thereby transferring the mold body;

[0069] 3. The locking sleeve and the second locking component are designed to fix the mold frame inside the second docking frame.

[0070] In this embodiment, the second locking member 34 includes a positioning plate 341. One end of the positioning plate 341 is fixed to the outer wall of the second docking frame 33, and the other end of the positioning plate 341 is vertically slidably provided with a third locking block 342. A first spring rod 343 is installed between the outer end of the third locking block 342 and the positioning plate 341. The inner end of the third locking block 342 has an arc-shaped structure facing the side of the mold positioning assembly 2.

[0071] In the above scheme, the third locking block can be retracted by force without affecting the entry and exit of the mold body. The arc-shaped structure design facilitates the cooperation of the third locking block.

[0072] In this embodiment, the first locking member 26 includes a first locking block 261, which is vertically disposed on the outer wall of the movable rod 25. An L-shaped second locking block 262 is vertically disposed on the side of the first locking block 261 near the mold storage assembly 3. The outer ends of the first locking block 261 and the second locking block 262 are both arc-shaped structures facing the mold storage assembly 3. The first locking block 261 is inserted into the locking sleeve 43, and the second locking block 262 is used to retract by pre-contacting the third locking block 342.

[0073] In the above scheme, the first locking component is designed with two sets of first locking blocks and second locking blocks. The first locking block is inserted into the locking sleeve to achieve positioning. The second locking block can abut against the third locking block in advance, so that the mold frame can enter the second docking frame. The second locking block is designed as an L-shape, so that the locking sleeve can be fitted onto the first locking block.

[0074] In this embodiment, the movable positioning member 42 includes a gripping plate 421. The inner wall of the gripping plate 421 is vertically and symmetrically provided with insertion rods 423. The insertion rods 423 slide through the main frame 41 and their inner ends are fitted into the side positioning holes 92. A second spring rod 422 is installed between the gripping plate 421 and the main frame 41.

[0075] In the above solution, pressing down the gripping plate causes the insert rod to detach from the mold body, and the second spring rod retracts, enabling the mold body to be quickly removed.

[0076] Example 2

[0077] To enable the cooling components to achieve the aforementioned coordinated adjustment effect, based on the above embodiments, this embodiment further provides the following:

[0078] In this embodiment, each main frame 41 has a set of linkage toothed plates 44 at the bottom of its outer wall, and the lengths of each linkage toothed plate 44 are different.

[0079] In the above scheme, the design of the linkage gear plate can achieve the following effects:

[0080] 1. Different lengths of linkage toothed plates drive the transfer adjustment component to rotate in different numbers of revolutions, thereby changing the cooling conveying path and making the linkage adjustment process more targeted and highly matched;

[0081] 2. When the mold frame is removed, the linkage toothed plate moves in the opposite direction, which drives the transfer adjustment component to rotate a specified number of times, so that the transfer adjustment component is reset. In this way, when the next mold frame and mold body are installed, its linkage adjustment process is not affected by the previous mold frame.

[0082] In this embodiment, the transfer adjustment component 6 includes a fixing block 61, which is fixed to the side wall of the cooling tank 51. A screw 62 is installed inside the fixing block 61 and rotates on its own. One end of the screw 62 is provided with a driven gear 621, and the other end is threaded. A mating plate 63 is fitted on the outside of the threaded end of the screw 62. A first constraint rod 64 is provided at a distance from the bottom of the mating plate 63. The first constraint rod 64 slides through the fixing block 61. Triangular blocks 65 are fixedly connected to the ends of the first constraint rod 64 and the mating plate 63. The triangular blocks 65 are connected to the guide component. In the second state, when the mold frame 4 has been moved, the rack meshes with the driven gear 621 to drive the triangular blocks 65 backward to reset the guide component. In the third state, when the mold frame 4 has not been moved, the rack meshes with the driven gear 621 to drive the triangular blocks 65 forward to adjust the cooling guide path of the guide component.

[0083] In the above scheme,

[0084] 1. The design of the screw and the driven gear and linkage gear plate at the end enables the transmission of force;

[0085] 2. The screw can drive the mating plate to move, and the first constraint rod can constrain and guide the movement of the mating plate;

[0086] 3. The triangular block is designed to expand two sets of upper and lower linkage components simultaneously, so as to realize the synchronous adjustment of the first guide roller and the second guide roller.

[0087] In this embodiment, the guiding assembly includes a first guide roller 52, a second guide roller 53, and a guiding control assembly 7. The guiding control assembly 7 includes a lower linkage assembly and an upper linkage assembly. The first guide roller 52 and the second guide roller 53 are sequentially and spaced apart along the conveying direction inside the cooling tank 51. Both ends of the first guide roller 52 and the second guide roller 53 are vertically and elastically slidably installed in the guide side plate 54. Each second guide roller 53 is located above the first guide roller 52. The extruded flame-retardant strip passes sequentially through the bottom surface of the first guide roller 52 and the top surface of the second guide roller 53. Each group of first guide rollers 52 is connected to the lower linkage assembly, and each group of second guide rollers 53 is connected to the upper linkage assembly.

[0088] In the above scheme, the design of the first guide roller and the second guide roller can realize the serpentine conveying of the flame retardant strip. When the first guide roller and the second guide roller come close to each other, the conveying bending amplitude is reduced and the conveying time is reduced, so as to meet the conveying needs of flame retardant strips with smaller inner diameter.

[0089] When the first guide roller and the second guide roller separate from each other, the conveying bending amplitude increases and the conveying time increases to meet the conveying needs of flame-retardant strips with larger inner diameters;

[0090] Springs are embedded at the sliding positions of the first and second guide rollers and the guide side plate. When the first guide roller moves downward and the second guide roller moves upward, the springs are compressed to facilitate subsequent reset. At the same time, they can also buffer part of the conveying force and prevent the conveyor from being pulled hard.

[0091] In this embodiment, the upper linkage assembly includes an upper linkage crossbar 72, and multiple sets of first linkage vertical bars 73 are vertically spaced on the bottom surface of the upper linkage crossbar 72. The bottom end of each set of first linkage vertical bars 73 is connected to a set of second guide rollers 53. An upper mating block 71 is provided in the middle of the outer wall of the upper linkage crossbar 72. The lower linkage assembly includes a lower linkage crossbar 74, and multiple sets of second linkage vertical bars 75 are vertically spaced on the bottom surface of the lower linkage crossbar 74. The bottom end of each set of second linkage vertical bars 75 is connected to a set of first guide rollers 52. A lower mating block 76 is provided in the middle of the outer wall of the lower linkage crossbar 74.

[0093] Example 3

[0094] Based on the above embodiments, this embodiment further provides the following:

[0095] In this embodiment, the slitting mechanism 8 includes a main housing 81. Two sets of conveying rollers 82 are installed at the input end of the main housing 81. A conveying seat 83 is provided at the output end of the conveying rollers 82. Multiple conveying cavities 831 are opened inside the conveying seat 83. A stop assembly 85 is installed at the end of the conveying seat 83. A cutting assembly 84 is installed at the top of the end of the conveying seat 83.

[0096] The cutting assembly 84 includes an upper plate 841. A third drive rod 842 is vertically arranged on the bottom surface of the upper plate 841. The bottom end of the third drive rod 842 is connected to a cutting plate 843. The cutting plate 843 is fitted to the end of the conveying seat 83. The inner wall of the cutting plate 843 is provided with multiple sets of elastic pressure blocks 844. Each set of elastic pressure blocks 844 corresponds to a set of conveying chambers 831. The elastic pressure blocks 844 are used to press down the flame-retardant strips, and the cutting plate 843 is used to cut each flame-retardant strip at the same time.

[0097] The stop assembly 85 includes a stop plate 851. The outer wall of the stop plate 851 is provided with a second constraint rod 8511. The second constraint rod 8511 slides through the top of the bracket 852. The bracket 852 is connected to the main housing 81. The top of the bracket 852 is equipped with an adjusting screw 853 for adjusting the stop plate 851. The stop plate 851 is used to adjust the extension length of the flame retardant strip.

[0098] In the above scheme, the position of the stop plate can be changed by rotating the adjusting screw according to the required length of flame-retardant particles, so as to ensure the conveying accuracy of the flame-retardant strip;

[0099] Each conveyor roller transports the flame-retardant strips to the corresponding conveying chamber. When the end of the flame-retardant strip is in place, the third drive rod drives the cutting plate to descend. The elastic pressure block first presses down on each flame-retardant strip, and then the cutting plate continues to move downward, cutting off the end of each flame-retardant strip, causing the cut flame-retardant particles to fall into the box.
