[0032] In order to make the purpose, technical solutions and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0033] like Figure 1-7 As shown, an XPS insulation board extrusion equipment and extrusion production line includes an extruder provided with a discharge port, and further includes:

[0034] The primary feeding belt 22 and the secondary feeding belt 3 are flush with the discharge port;

[0035] A cooling component 23 is used to cool the material on the primary feeding belt 22 by blowing air;

[0036] The supporting assembly 4 includes a movable roller 41 rotatably disposed between the primary feed belt 22 and the secondary feed belt 3. The movable roller 41 is provided with a pointed portion 411 on its circumference to form a contact groove 412. The movable roller 41 is driven to rotate so that the pointed portion 411 sequentially contacts the lower portion of the material.

[0037] The cutting blade 21 is driven to vertically reciprocate relative to the rotation axis of the movable roller 41 to cut the material.

[0038] Specifically, it also includes a base frame 1, a primary feeding belt 22 and a secondary feeding belt 3 installed at the same height on the base frame 1, and one side of the primary feeding belt 22 is close to the discharge port of the extruder to receive the extruded strip lining material and transport the material toward the secondary feeding belt 3, and the cooling component 23 is arranged on the base frame 1 to be located above the primary feeding belt 22, and the cooling component 23 blows air to cool the material just extruded on the primary feeding belt 22 to reduce the residual temperature, so as to prevent the material from being difficult to recover after deformation due to the residual temperature, and the supporting component 4 and the cutting knife 21 are both located between the primary feeding belt 22 and the secondary feeding belt 3, and the movable roller 41 is axially freely rotatable. When the material is moved from the primary feeding belt 22 to the secondary feeding belt 3, the lower part of the material is supported by the pointed portion 411 of the movable roller 41, and the movement of the material applies a rotational thrust to the movable roller 41. , so that the movable roller 41 is pushed and rotated to match the conveying movement of the material, and there is a friction groove 412 between the pointed parts 411 of the movable roller 41. When the cutting knife 21 is driven to move vertically downward close to the material and the movable roller 41, the cutting knife 21 cuts the material and approaches the friction groove 412. At this time, the pointed parts 411 are located on both sides of the cutting point of the cutting knife 21 on the material to support and fix the material, thereby increasing the material stability when the cutting knife 21 cuts the material, thereby changing the traditional cutting method of bringing the cutting knife 21 close to the surface to: the knife cuts vertically downward and the two sides of the knife cutting point are the support points of the material, avoiding the problem of uneven cut surface caused by deformation caused by extrusion on the upper and lower sides of the cutting point of the material during cutting. Secondly, the cooling component 23 cools down to reduce the elasticity of the material, which can also increase the flatness of the cut surface of the material.

[0039] Furthermore, the cooling component 23 can be a rotating fan blade to supply air to the upper side of the first-level feeding belt 22 to cool the material, or it can be a compressed clean gas that is decelerated in the deceleration chamber and then supplied to the upper side of the first-level feeding belt 22 for cooling, or it can be a plate that repeatedly swings to fan the air to cool the upper side of the first-level feeding belt 22, or it can be other structural replacements for the cooling component 23 known to those skilled in the art.

[0040] Furthermore, the cutting knife 21 is vertically slidably arranged on the base frame 1 and is driven by a driving component 211 to drive the cutting knife 21 to slide back and forth vertically. The driving component 211 can use an electric push rod to drive the cutting knife 21 to slide back and forth, or a pneumatic telescopic cylinder to drive the cutting knife 21 to slide, or a motor cooperates with a gear plate to drive the cutting knife 21 to slide back and forth, or other driving components 211 known to those skilled in the art can be replaced.

[0041] In the above technical solution, the cooling component 23 is used to cool the material to reduce the elasticity of the material, and the pointed portion 411 of the movable roller 41 is used to support the two sides of the cutting point of the cutting knife 21 on the material, thereby changing the traditional cutting method of bringing the cutting knife 21 and the surface close to each other to: the knife cuts vertically downward and the two sides of the knife cutting point are the support points of the material, avoiding the problem of uneven cut surface caused by the upper and lower sides of the cutting point of the material being squeezed and deformed during cutting. Secondly, the cooling component 23 cools the material to reduce the elasticity of the material, and can also increase the flatness of the cut surface of the material.

[0042] As another embodiment provided by the present invention, the supporting assembly 4 further includes a movable seat 44 that is vertically movable, and the movable roller 41 is disposed on the movable seat 44;

[0043] The cutting blade 21 is driven to contact the contact groove 412 to push the movable roller 41 and the movable seat 44 to move vertically downward away from the primary feeding belt 22 and the secondary feeding belt 3 .

[0044] Specifically, such as Figure 2 As shown, the movable seat 44 is vertically slidably set on the base frame 1, and the movable roller 41 is rotatably set on the movable seat 44. In the default state, the movable roller 41 follows the material conveying and supports the material and rotates. When the cutting knife 21 moves vertically downward to cut the material and approaches the movable roller 41, the cutting knife 21 cuts the material and extends into the contact groove 412. After the cutting knife 21 cuts the material, it continues to vertically push the movable roller 41 and the movable seat 44 to move vertically downward away from the primary feeding belt 22 and the secondary feeding belt 3, thereby separating the contact between the tip of the cutting knife 21 and the cut plate, avoiding the plate from sticking to the cutting knife 21 and being lifted, displaced or even falling as the cutting knife 21 resets; secondly, the synchronous downward movement of the movable roller 41 and the cutting knife 21 can also ensure the complete cutting of the material.

[0045] Furthermore, an elastic member 45 is provided in the base frame 1 for driving the movable seat 44 to slide vertically upward and reset. When the cutting knife 21 drives the movable seat 44 and the movable roller 41 to slide vertically downward, the cutting knife 21 slides vertically upward and resets, and the elastic member 45 drives the movable seat 44 and the movable roller 41 to slide vertically upward to reset to the position of supporting the lower part of the strip material, so as to facilitate the transportation of the strip material and the support and the next cutting of the material by the cutting knife 21.

[0046] As another embodiment provided by the present invention, it also includes a turning assembly 5, which includes a turning seat 51, and the secondary feeding belt 3 includes a driving wheel 31, a driven wheel 32 and a feeding belt surface 33. The turning seat 51 is horizontal in the default state and parallel to the upper part of the feeding belt surface 33. The movable seat 44 is driven to move downward to drive the turning seat 51 to turn over and become inclined through the transmission assembly 6, and the contact roller 52 arranged on the turning seat 51 contacts the pointed protrusion on the upper part of the feeding belt surface 33 to form two inclined surfaces.

[0047] Specifically, such as Figure 4 As shown, the secondary feeding belt 3 includes a driving wheel 31, a driven wheel 32 and a feeding belt surface 33 which is simultaneously mounted on the driving wheel 31 and the driven wheel 32. The driving wheel 31 is driven by a driving device to rotate, thereby driving the feeding belt surface 33 to move and the driven wheel 32 to rotate. The driving device can be a motor that cooperates with a gear set to drive the driving wheel 31 to rotate. The driving device of the driving wheel 31 is common technical knowledge for those skilled in the art and will not be described in detail here.

[0048] When the cutting blade 21 is not started to cut the strip material, the primary feeding belt 22 and the secondary feeding belt 3 are both started to move and transport the material. Figure 2 As shown, the flip seat 51 is in a default state at this time so as to be in a horizontal state, and the two ends of the flip seat 51 are rotatably provided with a resistance roller 52, and the two resistance rollers 52 are in contact with the inner side of the upper end of the feeding belt surface 33, thereby providing a horizontal support for the upper end of the feeding belt surface 33, thereby increasing the feeding stability of the feeding belt surface 33; and when the cutting knife 21 starts to cut the strip material, the cutting knife 21 cuts the material and pushes the movable roller 41 and the movable seat 44 to move vertically downward, and the movable seat 44 flips the flip seat 51 through the transmission assembly 6 to be in an inclined state, as shown in FIG. Figure 7 As shown, at this time, the right end of the flip seat 51 is the first end, and the right end is in a low position, the left end of the flip seat 51 is the second end, and the left end is in a high position, and the left end of the flip seat 51 is in a high position and tilted upward to make the resistance roller 52 resist the upper end of the feeding belt surface 33 to protrude upward, thereby forming two inclined surfaces on the upper end of the feeding belt surface 33, and the plate-like material cut by the cutting knife 21 is located on the feeding belt surface 33, and the left end of the flip seat 51 is close to the driven wheel 32, thereby making the side of the plate-like material facing away from the cutting knife 21 fall on the inclined surface of one side of the feeding belt surface 33 by gravity to be inclined, and the side of the plate-like material close to the cutting knife 21 is tilted to leave the feeding belt surface 33, thereby avoiding the pressure generated during cutting so that the end of the plate-like material close to the cutting knife 21 adheres to the feeding belt surface, causing difficulty in unloading.

[0049] An elastic tensioning wheel should also be provided in the secondary feeding belt 3, which is used to drive the feeding belt surface 33 of the secondary feeding belt 3 to always maintain a tensioned state. Even if the upper end of the feeding belt surface 33 is pushed upward by the flip seat 51 and the resistance roller 52, the elastic tensioning wheel can change the tensioning force to keep the feeding belt surface in a tensioned state. The tensioning wheel is common technical knowledge of technicians in this field and will not be elaborated here.

[0050] Furthermore, due to the deformation of the feed belt surface 33, the plate-like material thereon is tilted, and the left end of the plate-like material is tilted upward. When the cutting knife 21 slides vertically and rises to reset, the flip seat 51 is also driven to rotate and reset to a horizontal state to return to the default state. At this time, the upper end of the feed belt surface 33 is also restored to a horizontal state, so the left end of the plate-like material moves downward to fall back on the horizontal feed belt surface 33. Since the left end of the plate-like material moves, it can fan the air to the side of the cutting knife 21, thereby achieving fan cooling of the cutting knife 21, avoiding the cutting knife 21 from wearing out due to the high temperature.

[0051] Furthermore, the transmission assembly 6 can be a gear-coordinated connecting rod assembly engaged with the movable seat 44 to drive the flip seat 51 to flip, or it can be a sensor and a motor that drive the flip seat 51 to flip, or it can be any other structural replacement of the transmission assembly 6 known to those skilled in the art that can drive the flip seat 51 to flip when the movable seat 44 slides.

[0052] Another embodiment provided by the present invention further includes a dust suction pipe 8 connected to the hollow cavity of the movable roller 41 , and a plurality of dust suction holes 4111 communicating with the hollow cavity are formed on the pointed portion 411 .

[0053] Specifically, such as Figure 5 As shown, a plurality of dust suction holes 4111 are provided on the pointed portion 411, and one end of the dust suction pipe 8 is connected to the hollow cavity in the movable roller 41, and the other end is connected to an external dust suction device, thereby providing suction on the dust suction holes 4111 to absorb and remove debris generated by the cutting blade 21 during the cutting process, preventing the debris from flying and facilitating cleaning. The dust suction holes 4111 are provided on the side of the pointed portion 411. When the cutting blade 21 is driven downward to cut the material, the tip of the cutting blade 21 will contact the side of the pointed portion 411 and move up and down to slide into the contact groove 412, thereby causing the cutting blade 21 to scrape against the dust suction holes 4111 to prevent the dust suction holes 4111 from being blocked. Secondly, since the upper end of the feeding belt surface 33 is in the shape of two inclined surfaces, the debris generated by cutting and falling on the feeding belt surface 33 can easily slide along the inclined surface toward the movable roller 41, and then be sucked and removed by the suction force generated by the dust collection holes 4111 on the movable roller 41, thereby avoiding excessive debris remaining on the conveyor belt surface 33.

[0054] As another embodiment provided by the present invention, a flexible contact member 42 is provided in the interference groove 412 , and a sharpening block 43 is provided on the flexible contact member 42 and protrudes into the interference groove 412 in a circumferentially inclined manner.

[0055] Specifically, such as Figure 5As shown, the flexible contact member 42 is arranged in the interference groove 412, and the sharpening block 43 is arranged on the flexible contact member 42 and protrudes obliquely toward the inner circumference of the interference groove 412. When the cutting knife 21 cuts the material and slides down along the side of the pointed portion 411 into the interference groove 412, the tip of the cutting knife 21 gradually slides into the bottom of the interference groove 412. The tip of the cutting knife 21 slides along the upper surface of the sharpening block 43 during the sliding process, thereby causing the cutting knife 21 to generate a thrust on the movable roller 41. After the movable roller 41 is pushed toward one side of the secondary feeding belt 3 and rotates a certain distance, the cutting knife 21 contacts the bottom of the flexible contact member 42, causing the movable roller 41 to rotate toward the side of the primary feeding belt 22, thereby causing the plate supported on the movable roller 41 to be fed to the right. When the cutting knife 21 moves downward and contacts the flexible contact member 42, the movable roller 41 rotates to feed the plate to the right, preventing the plate from sticking to the cutting knife 21 and being lifted, displaced, or even falling as the cutting knife 21 returns to its original position.

[0056] When the cutting knife 21 moves vertically upward and resets, the cutting knife 21 moves upward to contact the tip of the sharpening block 43, so that the sharpening block 43 sharpens the cutting knife 21 to increase the sharpness of the blade.

[0057] Another embodiment provided by the present invention further includes a movable plate 7 on which a fur covering portion 71 is provided. The movable seat 44 is driven downward so that the fur covering portion 71 of the movable plate 7 extends into the abutment groove 412 and rubs against the flexible contact member 42.

[0058] Specifically, such as Figure 3 As shown, a vertical sliding groove 441 is provided on the movable seat 44, and the movable plate 7 is slidably arranged in the vertical sliding groove 441, and a push portion 11 aligned with the vertical sliding groove 441 is provided on the base frame 1. When the movable seat 44 and the movable roller 41 are pushed vertically downward by the cutting knife 21, the movable seat 44 approaches the push portion 11 so that the push portion 11 extends into the vertical sliding groove 441, and the push portion 11 pushes the movable plate 7 to rise vertically so that the fur covering portion 71 provided on the movable plate 7 extends into the contact groove 412 facing away from the cutting knife 21 and rubs against the flexible contact member 42, and the flexible contact member 42 is made of rubber. The fur-covered portion 71 rubs against the flexible contact piece 42 made of rubber to generate static electricity on the flexible contact piece 42, and when the movable roller 41 rotates subsequently, the static electricity can be used to absorb debris or dust that falls during the operation. Moreover, since the axial lengths of the movable roller 41 and the fur-covered portion 71 are both long, the contact area between the flexible contact piece 42 and the fur-covered portion 71 is large, so that the friction generated by the flexible contact piece 42 and the fur-covered portion 71 once can also generate static electricity sufficient to absorb dust, and the absorbed dust is then removed by the grooves opened on the flexible contact piece 42 and through the dust suction pipe 8.

[0059] Among them, the push portion 11 is set on the base frame 1, and the movable seat 44 is driven to slide close to the base frame 1, then the push portion 11 only needs to be aligned with the vertical sliding groove 441 and can be extended into the vertical sliding groove 441, then the movable seat 44 is close to the base frame 1 so that the push portion 11 can be extended into the vertical sliding groove 441, and the push portion 11 pushes the movable plate 7 to slide close to the movable roller 41, and the push portion 11 can also be as Figure 2 As shown in .

[0060] Furthermore, a through groove may be provided at the bottom of the flexible contact member 42 to communicate with the interior of the movable roller 41, so that dust or debris stuck on the flexible contact member 42 due to static electricity can be adsorbed and removed through the through groove.

[0061] When static electricity is generated on the flexible contact member 42 due to friction with the fur covering portion 71, if the cutting knife 21 approaches and collides with the statically charged flexible contact member 42 during the cutting operation, the static electricity on the flexible contact member 42 can absorb and remove the debris stuck on the cutting knife 21.

[0062] As another embodiment provided by the present invention, the flip seat 51 is provided with an extension portion 511 extending to the outside of the feeding belt surface 33. The flip seat 51 is driven to flip in an inclined shape so that the stabilizing roller 53 provided on the extension portion 511 and the driven wheel 32 clamp the feeding belt surface 33.

[0063] Specifically, such as Figure 4 As shown, the flip seat 51 is located on the inner ring side of the feed belt surface 33, and the protruding portion 511 of the flip seat 51 protrudes to the bottom of the outer ring side of the feed belt surface 33. At this time, the protruding portion 511 is located on both sides of the feed belt surface 33 to limit the axial direction of the driven wheel 32 of the feed belt surface 33, thereby preventing the feed belt surface 33 from tilting along the axial direction of the driven wheel 32 during operation, thereby causing the feed belt surface 33 to be aggravated in wear.

[0064] Furthermore, when the turning seat 51 is driven by the movable seat 44 and the transmission assembly 6 to turn over and become tilted, as shown in FIG. Figure 4 As shown, the protruding portion 511 follows the rotation of the flip seat 51 to make the stabilizing roller 53 rotate close to the driven wheel 32, thereby making the stabilizing roller 53 and the driven wheel 32 clamp the feeding belt surface 33, thereby increasing the running stability of the feeding belt surface 33, and further since the upper end of the feeding belt surface 33 is pushed upward by the contact roller 52, the wrap angle between the feeding belt surface 33 and the driven wheel 32 is reduced, and the stabilizing roller 53 presses the lower part of the feeding belt surface 33 against the driven wheel 32 to increase the wrap angle between the feeding belt surface 33 and the driven wheel 32 again, avoiding the problem of slipping of the feeding belt surface 33 due to the small wrap angle between the feeding belt surface 33 and the driven wheel 32, thereby ensuring the running stability of the feeding belt surface 33.

[0065] As another embodiment provided by the present invention, the turning seat 51 is turned over to be tilted so that the stabilizing roller 53 is located on the vertical moving path of the movable roller 41 to drive the movable roller 41 to rotate.

[0066] Specifically, such as Figure 2 As shown, when the movable roller 41 does not move vertically downward, the turning seat 51 is in the default state, and the stabilizing roller 53 is not turned over and is not on the vertical moving path of the movable roller 41, as shown in FIG. Figure 7 As shown, when the movable roller 41 and the movable seat 44 move vertically downward, the flip seat 51 is driven by the transmission assembly 6 to rotate gradually, and when the movable roller 41 moves vertically downward to the lower side of the stabilizing roller 53, the flip seat 51 flips over to make the stabilizing roller 53 move to the vertical moving path of the movable roller 41, and then the stabilizing roller 53 and the driven wheel 32 clamp the feeding belt surface 33, and when the cutting knife 21 moves vertically upward and resets, the elastic member 45 drives the movable seat 44 to move vertically upward for reset, and at this time, in the process of the movable roller 41 following the movable seat 44 to move vertically upward, the stabilizing roller 53 follows the flip seat 51 to gradually rotate and reset but is still located on the vertical moving path of the movable roller 41, so the movable roller 41 moves close to the secondary feeding belt 3 in the process of moving vertically upward. The pointed portion 411 on one side contacts the stabilizing roller 53, and the movable roller 41 continues to move vertically upward so that the pointed portion 411 is moved by the stabilizing roller 53 and the movable roller 41 is driven to rotate to the side of the secondary feeding belt 3, so that the movable roller 41 rotates and rises to support the strip-shaped material, preventing the pointed portion 411 from rising directly and poking into the material to cause damage to the material; and the flexible contact piece 42 with static electricity also rotates circumferentially, and the stabilizing roller 53 can squeeze and adhere the material debris on the secondary feeding belt 3, and the flexible contact piece 42 absorbs and removes the debris or dust on the feeding belt surface 33 and the stabilizing roller 53 while rotating circumferentially, and then the stabilizing roller 53 follows the flip seat 51 to return to its original position away from the movable roller 41.

[0067] As another embodiment provided by the present invention, the transmission assembly 6 includes a rotatable worm 61 and a rotating rod 62, the worm 61 is provided with a gear portion 611 coupled to the tooth plate portion 442 of the movable seat 44, the rotating rod 62 is provided with a worm wheel portion 621 coupled to the worm 61, and a transmission rope 63 is fixedly wound around the rotating rod 62, and the other end of the transmission rope 63 is fixedly connected to the first end of the flip seat 51.

[0068] Specifically, such as Figure 2As shown, a tooth plate portion 442 is provided on the movable seat 44, and the worm 61 and the rotating rod 62 are both rotatably set on the base frame 1, the tooth plate portion 442 is engaged with the gear portion 611 of the worm 61, and the worm wheel portion 621 is engaged with the worm 61, so that when the movable seat 44 is driven to move vertically, the worm 61 drives the rotating rod 62 to rotate axially, and one end of the transmission rope 63 is fixedly wound on the winding groove 622 of the rotating rod 62, and the other end of the transmission rope 63 is turned through the rope winding roller 64 rotatably set on the base frame 1 to be fixedly connected to the first end of the flip seat 51. When the movable seat 44 is driven to move downward, the worm 61 is driven to rotate so that the rotating rod 62 rotates clockwise and then winds and retracts the transmission rope 63, so that the other end of the transmission rope 63 pulls the first end of the flip seat 51, so that the flip seat 51 flips and becomes tilted; and when the movable seat 44 is driven to move vertically upward, the worm 61 is driven to rotate so that the rotating rod 62 rotates counterclockwise and then releases the transmission rope 63, so that the other end of the transmission rope 63 no longer pulls the first end of the flip seat 51, so that the flip seat 51 is reset to the default state.

[0069] The turning seat 51 is driven to turn over by the worm gear 621, the worm 61 and the transmission rope 63, so that the rotating rod 62 has a self-locking effect, thereby preventing the turning seat 51 and the contact roller 52 from wearing the transmission belt surface 33 due to accidental release or tension of the transmission rope 63.

[0070] Working principle: One side of the primary feeding belt 22 is close to the discharge port of the extruder to receive the extruded strip lining material and convey the material to the secondary feeding belt 3. The lower part of the material is supported by the pointed portion 411 of the movable roller 41, and the movement of the material applies a rotational thrust to the movable roller 41, so that the movable roller 41 is pushed and rotated to match the conveying movement of the material. When the cutting knife 21 is driven to move vertically downward close to the material and the movable roller 41, the cutting knife 21 cuts the material and approaches the contact groove 412. At this time, the pointed portion 411 is located on both sides of the cutting point of the cutting knife 21 to support and fix the material. After the cutting knife 21 cuts the material, it moves along the pointed portion 411. When the side of the shaped portion 411 slides down into the abutment groove 412, the tip of the cutting knife 21 gradually slides into the bottom of the abutment groove 412. During the sliding process, the tip of the knife slides along the upper surface of the sharpening block 43, thereby causing the cutting knife 21 to generate a thrust on the movable roller 41. After the movable roller 41 is pushed toward one side of the secondary feeding belt 3 and rotates a certain distance, the cutting knife 21 abuts against the bottom of the flexible contact member 42, causing the movable roller 41 to rotate toward the side of the primary feeding belt 22, thereby causing the plate supported on the movable roller 41 to be sent to the right. At this time, the dust suction hole 4111 has suction to absorb and remove the debris generated by the cutting knife 21 in the process of cutting the material.

[0071] After the cutting knife 21 cuts the material, it continues to vertically push the movable roller 41 and the movable seat 44 to move vertically downward away from the primary feeding belt 22 and the secondary feeding belt 3, and the worm 61 is driven to rotate to make the rotating rod 62 rotate clockwise and thus wind up the transmission rope 63, so that the other end of the transmission rope 63 pulls the first end of the flip seat 51, so that the flip seat 51 flips and tilts, and the left end of the flip seat 51 is located at a high position and tilts upward to make the contact roller 52 push against the upper end of the feeding belt surface 33 to protrude upward, and the side of the plate-like material close to the cutting knife 21 is tilted to leave the feeding belt surface 33; and the protruding portion 511 follows the rotation of the flip seat 51 to make the stabilizing roller 53 rotate close to the driven wheel 32, so that the stabilizing roller 53 and the driven wheel 32 clamp the feeding belt surface 33;

[0072] At the same time, the movable seat 44 approaches the pushing portion 11 so that the pushing portion 11 extends into the vertical sliding groove 441. The pushing portion 11 pushes the movable plate 7 to rise vertically so that the fur covering portion 71 provided on the movable plate 7 extends into the contact groove 412 facing away from the cutting knife 21 and rubs against the flexible contact member 42. The flexible contact member 42 is a rubber member. The fur covering portion 71 rubs against the rubber flexible contact member 42 to generate static electricity on the flexible contact member 42. When the movable roller 41 subsequently rotates, the static electricity can be used to absorb debris or dust dropped during operation.

[0073] When the cutting knife 21 moves vertically upward to reset, the cutting knife 21 moves upward to contact the tip of the grinding block 43, so that the grinding block 43 grinds the cutting knife 21 to increase the sharpness of the blade, and the elastic member 45 drives the movable seat 44 to move vertically upward for reset. At this time, the movable roller 41 follows the movable seat 44 to move vertically upward. The pointed portion 411 of the movable roller 41 close to the side of the secondary feeding belt 3 contacts the stabilizing roller 53, and the movable roller 41 continues to move vertically upward so that the pointed portion 411 is moved by the stabilizing roller 53, so that the movable roller 41 is driven to rotate toward the side of the secondary feeding belt 3, so that the movable roller 41 rotates and then rises to support the strip-shaped material. The fur-covered portion 71 rubs against the rubber flexible contact piece 42 to generate static electricity on the flexible contact piece 42, and when the movable roller 41 rotates subsequently, the static electricity can be used to absorb debris or dust that falls during operation.

[0074] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
