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.

[0031] like Figure 1-10As shown, a highly antibacterial rubber is composed of the following raw materials in parts by weight: 15-20 parts of styrene-butadiene rubber, 20-25 parts of EPDM rubber, 15-20 parts of silicone rubber, 5-10 parts of polyvinyl chloride, 5-7 parts of antioxidant, 5-10 parts of graphite powder, 1-3 parts of sulfur, 1-3 parts of benzoyl peroxide, 1-2 parts of dioctyl adipate, 0.2-0.5 parts of silver-loaded zirconium phosphate, 3-5 parts of diatomaceous earth, 1-3 parts of montmorillonite, 2-4 parts of boron carbide, 2-4 parts of white mineral oil, 2-4 parts of magnesium stearate, 0.5-1 parts of polyamide wax micropowder, 0.1-0.5 parts of shell powder, 0.1-0.5 parts of stannous oxide, 2-5 parts of zinc borate, 0.2-0.5 parts of chitosan, 0.5-1 parts of nano-iron oxide, and 1-3 parts of antibacterial additives.

[0032] Specifically, the highly antibacterial rubber is composed of the following raw materials in parts by weight: 15-20 parts of styrene-butadiene rubber, 20-25 parts of EPDM rubber, 15-20 parts of silicone rubber, 5-10 parts of polyvinyl chloride, 5-7 parts of antioxidant, 5-10 parts of graphite powder, 1-3 parts of sulfur, 1-3 parts of benzoyl peroxide, 1-2 parts of dioctyl adipate, 0.2-0.5 parts of silver-loaded zirconium phosphate, 3-5 parts of diatomaceous earth, 1-3 parts of montmorillonite, 2-4 parts of boron carbide, 2-4 parts of white mineral oil, 2-4 parts of magnesium stearate, 0.5-1 parts of polyamide wax powder, 0.1-0.5 parts of shell powder, 0.1-0.5 parts of stannous oxide, 2-5 parts of zinc borate, 0.2-0.5 parts of chitosan, 0.5-1 parts of nano-iron oxide, and 1-3 parts of antibacterial additives.

[0034] In the above technical solution, the antibacterial additive raw materials in the highly antibacterial rubber are used to improve the antibacterial property of the formed rubber, reduce the bacterial growth on the surface of the rubber product, and improve the safety to the human body.

[0035] Embodiment 2

[0036] The present embodiment is used for calendering a rubber sheet formed by mixing and preparing the highly antibacterial rubber in the first embodiment, and specifically comprises rubber baffle plates 1 symmetrically arranged on both sides of the rubber sheet, a mounting seat 21 being provided on the rubber baffle plates 1, a rubber tapping knife 3 and a support rod 22 being installed on the mounting seat 21, a blade portion 32 of the rubber tapping knife 3 extending obliquely away from the rubber baffle plate 1 so that the edge portion of the blade portion 32 is located on the front side of the rubber baffle plate 1, and the support rod 22 abuts against the side of the blade portion 32 close to the rubber baffle plate 1.

[0037] Specifically, Figure 1 As shown, the rubber baffle plates 1 are arranged symmetrically, and the rubber baffle plates 1 should be arranged on the rear side of the calendering roller of the calendering equipment. When the calendering roller rotates to calender and feed the rubber raw material, the calendered rubber sheet moves horizontally from between the rubber baffle plates 1 to be transported away from the calendering equipment, and the rubber baffle plates 1 block the horizontal sides of the rubber sheet to reduce the horizontal jitter deviation of the rubber sheet during the transportation process, thereby improving the transportation stability of the rubber sheet during the calendering process. The calendering rollers in the calendering equipment are common technical knowledge of technicians in this field and are not elaborated here.

[0038] When the rubber is calendered, the rubber raw material is calendered from a rough blank state to a strip of a certain thickness by the calendering roller of the calendering equipment to facilitate the subsequent processing flow, and the rubber tapping knife 3 is often symmetrically arranged on the rear side of the calendering roller of the calendering equipment, and the rubber tapping knife 3 is used to cut both sides of the strip-shaped rubber sheet at the calendering position to directly adjust the width of the rubber sheet, and the rubber tapping knife 3 is often in the form of a sheet, and the rubber tapping knife 3 is made parallel to the side of the rubber sheet. When the rubber sheet moves and is transported past the rubber tapping knife 3, the blade of the rubber tapping knife 3 cuts the side of the rubber sheet, but the rubber sheet will also contact the blade of the rubber tapping knife 3 during the movement, which will cause the blade temperature of the rubber tapping knife 3 to rise rapidly, which will cause the rubber tapping knife 3 to be easily damaged due to deformation and bending due to temperature increase, and the side of the rubber sheet is not cut evenly.

[0039] A mounting seat 21 is provided on the rubber baffle plate 1, and a mounting portion 31 and a blade portion 32 are provided on the rubber cutting knife 3, and there is an angle between the mounting portion 31 and the blade portion 32. The mounting portion 31 of the rubber cutting knife 3 is mounted on the mounting seat 21 so that the blade portion 32 extends to the front end of the rubber baffle plate 1, and the inclined shape of the blade portion 32 extends toward the rubber sheet between the rubber baffle plates 1 so that the blade portion of the blade portion 32 contacts the side of the rubber sheet, and a support rod 22 is also provided on the mounting seat 21, and the support rod 22 is supported on the side of the blade portion 32 facing the rubber baffle plate 1. When the rubber sheet is pressed and moved between the rubber baffle plates 1, the blade portion of the blade portion 32 cuts both sides of the rubber sheet to The rubber sheet is trimmed to a predetermined width, and since the blade portion 32 is inclined so that the blade portion extends toward the rubber sheet for cutting, the rubber sheet will not contact the blade portion 32 of the rubber tapping knife 3 during transportation, thereby reducing the frictional heat and contact jitter between the blade portion 32 and the rubber sheet, and improving the service life and cutting stability of the rubber tapping knife 3. The support rod 22 is supported on the side of the blade portion 32 close to the rubber baffle 1, so that the support rod 22 can improve the supporting effect on the rubber tapping knife 3 when the rubber tapping knife 3 cuts the rubber sheet, thereby further improving the cutting stability of the rubber tapping knife 3, reducing the pressure deformation of the blade portion 32 of the rubber tapping knife 3, and improving the cutting smoothness of the rubber tapping knife 3 on the side of the rubber sheet.

[0040] In the above technical scheme, the mounting portion 31 of the rubber tapping knife 3 is mounted on the mounting seat 21 so that the blade portion 32 extends to the front end of the rubber baffle plate 1, and the inclined shape of the blade portion 32 extends toward the rubber plate between the rubber baffle plates 1 so that the edge of the blade portion 32 contacts the side of the rubber plate, thereby preventing the rubber plate from contacting the blade portion 32 of the rubber tapping knife 3 during transportation, thereby reducing the frictional heat and contact jitter between the blade portion 32 and the rubber plate, and improving the service life and cutting stability of the rubber tapping knife 3. The support rod 22 is supported on the side of the blade portion 32 close to the rubber baffle plate 1, thereby enabling the support rod 22 to improve the supporting effect on the rubber tapping knife 3 when the rubber tapping knife 3 cuts the rubber plate, thereby further improving the cutting stability of the rubber tapping knife 3, reducing the pressure deformation of the blade portion 32 of the rubber tapping knife 3, and improving the cutting smoothness of the rubber tapping knife 3 on the side of the rubber plate.

[0041] As another embodiment provided by the present invention, it also includes a base 51 on which a threaded rod 52 is rotatably arranged, and the rubber baffle plate 1 is symmetrically slidably arranged on the base 51, and the rubber baffle plate 1 is threadably matched with the threaded rod 52.

[0042] Specifically, Figure 3As shown, a sliding portion 13 is provided on the rubber baffle plate 1, and a sliding groove 512 is provided on the base 51. The sliding portion 13 is slidably arranged in the sliding groove 512 so that the two rubber baffle plates 1 are symmetrically arranged on the base 51 and slide relative to each other, and the threaded rod 52 is symmetrically provided with threaded portions with threads facing opposite directions, and the two threaded portions are respectively threadedly matched with the threaded matching holes 11 of the two rubber baffle plates 1, thereby driving the threaded rod 52 to rotate so that the two rubber baffle plates 1 slide closer or farther relative to each other, and the rubber baffle plate 1 can drive the rubber cutting knife 3 to move relative to each other synchronously to achieve the width adjustment of the strip rubber sheet at the calendering location, which is convenient for the calendering production and transportation of strip rubber sheets of different widths and improves the molding efficiency of the rubber sheet. Among them, a driving motor can be provided in the base 51 to drive the threaded rod 52 to rotate. The driving motor and its electrical connection are common technical knowledge known to those skilled in the art and are not described in detail here.

[0043] As another embodiment provided by the present invention, the mounting seat 21 is rotatably arranged on the rubber baffle plate 1, and a transmission assembly 8 is arranged in the rubber baffle plate 1. The transmission assembly 8 includes a gear ring seat 81 arranged coaxially with the mounting seat 21. The two rubber baffle plates 1 are driven to slide relative to each other so that the gear ring seat 81 is driven to drive the mounting seat 21 to rotate, and the rubber cutting knife 3 and the support rod 22 are synchronously rotated vertically following the mounting seat 21 so that the vertical angle between the blade portion of the blade body portion 32 and the rubber plate is reduced.

[0044] Specifically, Figure 2 As shown, the mounting seat 21 is rotatably arranged on the rubber baffle plate 1, and the rotation axis of the mounting seat 21 is perpendicular to the mounting portion 31 of the rubber tapping knife 3, and the gear ring seat 81 is coaxially fixed with the mounting seat 21. When the rubber baffle plate 1 is located in the initial position so that the rubber tapping knife 3 cuts the rubber sheet with a small thickness, the mounting seat 21 is located in the default position so that the blade of the rubber tapping knife 3 is perpendicular to the rubber sheet, that is, the rubber sheet is transported horizontally forward, and the blade portion 32 of the rubber tapping knife 3 is vertical so that the blade is directed toward both sides of the rubber sheet for cutting. When the blade of the rubber tapping knife 3 cuts the rubber sheet with a small thickness, the vertical arrangement of the blade and the rubber sheet can reduce the vertical deformation of the rubber sheet, thereby improving the cutting flatness of the side of the rubber sheet.

[0045] When the rubber baffle plates 1 are driven by the threaded rod 52 to slide relative to each other, if the two rubber baffle plates 1 slide relatively close to each other so that the rubber cutting knife 3 moves relatively close to each other, the rubber cutting knife 3 increases the cutting thickness of the rubber sheet due to the reduction in distance, and the width of the rubber sheet formed by the rubber sheet between the rubber baffle plates 1 is reduced. When the two rubber baffle plates 1 move relatively close to each other, the gear ring seat 81 is also driven to rotate, so that the gear ring seat 81 drives the mounting seat 21 to rotate axially, and the rubber cutting knife 3 on the mounting seat 21 rotates vertically following the rotation of the mounting seat 21, thereby causing the blade of the rubber cutting knife 3 to rotate and lift. The vertical angle between the blade 32 and the rubber sheet is reduced, that is, the angle between the blade 32 and the rubber sheet is reduced and no longer perpendicular to the rubber sheet. The greater the distance that the rubber baffle 1 drives the rubber tapping knife 3 to move closer, the smaller the angle between the rubber tapping knife 3 and the rubber sheet is when the mounting seat 21 rotates, thereby realizing that when the rubber tapping knife 3 increases the cutting width of the rubber sheet, the angle between the blade 32 and the advancing direction of the rubber sheet is reduced, thereby reducing the extrusion deformation force on the blade 32, and can also improve the cutting force of the blade 32 on the rubber sheet, and improve the side cutting flatness of the rubber sheet. Avoid deformation damage of the rubber tapping knife 3 due to the increased cutting pressure caused by the change of the cutting width of the rubber sheet.

[0046] As another embodiment provided by the present invention, a linear array of lateral guide wheels 4 that are in contact with both sides of the rubber plate are rotatably arranged on the rubber baffle plate 1, a support rod 22 is slidably arranged on the mounting seat 21, and a rubber support block 23 located in contact with the blade body portion 32 is arranged on the first end of the support rod 22, and the lateral guide wheels 4 are rotated by the push of the rubber plate to drive the support rod 22 to slide and squeeze the rubber support block 23.

[0047] Specifically, Figure 1As shown, lateral guide wheels 4 are arranged in a linear array on the rubber baffle plates 1, and rubber bearing blocks 23 are arranged on the support rods 22. When the rubber sheet is located between the rubber baffle plates 1 for horizontal movement and transportation, the two sides of the rubber sheet abut against the lateral guide wheels 4, and the rubber sheet is moved and transported to push the lateral guide wheels 4 for axial rotation. The existence of the lateral guide wheels 4 can improve the stability of the movement and transportation of the rubber sheet, reduce the lateral or vertical jitter of the rubber sheet during transportation, thereby improving the flatness of the rubber sheet when cut during transportation and improving the molding quality. When the rubber sheet is moved and transported between the rubber baffle plates 1, the support rod 22 is pushed by the rotation of the lateral guide wheel 4 to apply a supporting force to the rubber bearing block 23 and the blade portion 32, thereby improving the stability of the blade portion 32 of the rubber tapping knife 3 during the cutting of the rubber sheet, and avoiding the problem of deformation and damage of the rubber tapping knife 3 due to the cutting reaction force.

[0048] Since the support rod 22 is slidably mounted on the mounting seat 21, when the rubber baffle plate 1 is driven to slide relatively close to adjust the width of the rubber plate, the mounting seat 21 is driven to rotate to drive the rubber tapping knife 3 and the support rod 22 to rotate vertically synchronously, so that the support rod 22 can always play a supporting and bearing role when the rubber tapping knife 3 performs cutting operations.

[0049] As another embodiment provided by the present invention, a locking member 6 is threadedly installed on the support rod 22, and a truncated cone-shaped rubber wheel 61 is provided on the locking member 6. A driving portion 41 is provided on the lateral guide wheel 4, and a driving tooth 411 is provided in a circular array on the driving portion 41. An arc-shaped resistance bar 222 is provided in a linear array on the support rod 22. The rotation of the lateral guide wheel 4 drives the driving tooth 411 to rotate circumferentially and push the arc-shaped resistance bar 222 in turn to make the support rod 22 slide. The driving tooth 411 rotates circumferentially to squeeze the rubber wheel 61 to rotate so that the locking member 6 can move axially, and the locking end 62 of the locking member 6 extends out of the outer side of the mounting seat 21 and contacts the inside of the rubber baffle plate 1 to lock the mounting seat 21.

[0050] Specifically, Figure 8 As shown, a mounting hole 221 is provided on the support rod 22, and the locking member 6 is threadedly installed in the mounting hole 221. Fig. 9As shown, when the mounting base 21 is in the default state, the locking member 6 is vertical, and the support rod 22 is arranged horizontally, the rubber wheel 61 on the locking member 6 is truncated cone-shaped, and the lower bottom end circumference of the rubber wheel 61 of the locking member 6 in the default state is aligned with the driving portion 41 of the lateral guide wheel 4, and the driving portion 41 of the lateral guide wheel 4 is horizontally flush with the arc-shaped wheel 222 of the support rod 22.

[0051] When there is no rubber sheet output between the rubber baffle plates 1, the support rod 22 does not slide out of the mounting seat 21 to squeeze the rubber block 23. At this time, the arc-shaped abutment strip 222 of the support rod 22 cooperates with the driving tooth 411 on the driving portion 41 of the lateral guide wheel 4. When the rubber sheet moves between the rubber baffle plates 1, the lateral guide wheel 4 is pushed and rotated by the rubber sheet so that the driving portion 41 drives the driving tooth 411 to rotate circumferentially. The driving tooth 411 rotates to push the support rod 22 to slide out of the mounting seat 21 through the arc-shaped abutment strip 222 to squeeze the rubber block 23, thereby causing the support rod 22 and the rubber block 23 to apply a supporting force to the blade portion 32, and the support rod 22 slides to cause the rubber abutment wheel 61 of the locking member 6 to move to the position aligned with the driving portion 4. 1, and as the lateral guide wheel 4 continues to rotate, the driving part 41 will continuously squeeze and push the rubber wheel 61 to rotate, thereby causing the locking member 6 to rotate and move axially. At this time, the rubber wheel 61 moves axially toward the lateral guide wheel 4 while rotating, until the locking end 62 of the locking member 6 moves axially out of the outer side of the mounting seat 21 to abut against the rubber baffle 1, and then the locking member 6 is used to lock the mounting seat 21 and the support rod 22, so as to avoid the problem of random rotation and swing of the mounting seat 21 due to the cutting pressure or the sliding and loosening of the support rod 22 during the rubber sheet moving and conveying operation, thereby further improving the fixing stability of the rubber cutting knife 3 and improving the cutting smoothness of the rubber sheet.

[0052] Secondly, when the locking end 62 of the locking member 6 moves axially out of the outer side of the mounting seat 21 to abut against the rubber baffle plate 1, the rubber wheel 61 moves axially while rotating to the lower end of the truncated cone of the rubber wheel 61 to abut against the side of the lateral guide wheel 4 facing away from the rubber plate, and then the rubber wheel 61 is used to achieve lateral contact support for the lateral guide wheel 4 without squeezing the lateral guide wheel 4 to stop rotating due to friction. The rubber wheel 61 is used to achieve lateral support and friction deceleration for the lateral guide wheel 4, thereby improving the rotation stability of the lateral guide wheel 4 and avoiding the resonance problem caused by multiple lateral guide wheels 4 rotating synchronously and rapidly with the rubber plate, thereby further improving the stability of rubber plate transportation.

[0053] When the two rubber baffle plates 1 slide relatively close to each other to reduce the molding width of the rubber plate, the mounting seat 21 is driven to rotate so that the rubber cutting knife 3 and the support rod 22 are rotated and lifted vertically. At this time, the support rod 22 is rotated and lifted vertically, but the arc-shaped resisting strip 222 of the support rod 22 still cooperates with the driving tooth 411 on the driving part 41 of the lateral guide wheel 4, so that after the vertical lifting of the support rod 22, the lateral guide wheel 4 can still be driven to rotate to push the support rod 22 to slide out of the outer side of the mounting seat 21. After the support rod 22 slides out to squeeze the rubber bearing block 23, the lower end of the rubber resisting wheel 61 of the locking member 6 in the default state can still contact the driving part 41. Since the driving part 41 still squeezes the rubber resisting wheel 61, the lateral guide wheel 4 can also rotate so that the driving part 41 squeezes and pushes the rubber resisting wheel 61 to rotate, and drives the locking member 6 to move axially while rotating to lock the mounting seat 21 and the support rod 22.

[0054] As another embodiment provided by the present invention, a partially spiral raised contact strip 611 is arranged in a circumferential array on the outer ring surface of the rubber wheel 61, and an inner groove 42 is opened in a linear array on the lateral guide wheel 4. The locking member 6 is driven to move axially so that the lower end of the cone of the rubber wheel 61 moves to be flush with the lateral guide wheel 4 and squeezes the lateral guide wheel 4.

[0055] Specifically, Figure 8 As shown, a plurality of raised contact strips 611 are provided on the rubber wheel 61, and the raised contact strips 611 are partially spiral and arranged in a circumferential array, and a certain interval is provided between the plurality of raised contact strips 611 so as to facilitate the cooperation with the driving teeth 411 of the driving part 41 of the lateral guide wheel 4, thereby improving the stability of the driving part 41 squeezing and pushing the rubber wheel 61 to rotate. In the lateral guide wheel 4, inner grooves 42 are provided in a linear array, and during the moving and conveying process of the rubber sheet, the lateral guide wheel 4 is pushed and continuously rotated axially so that the inner grooves 42 also rotate circumferentially to contact the side of the rubber sheet, thereby utilizing the inner grooves 42 to reduce the vertical shaking of the rubber sheet during the conveying process and improve the conveying stability. When the rubber baffle plate 1 moves closer to increase the cutting thickness of the rubber sheet by the rubber tapping knife 3, the cutting pressure on the rubber tapping knife 3 increases. The larger cutting pressure may cause some small granular rubber debris to stick to the side of the rubber sheet and move with the rubber sheet. When the side of the rubber sheet moves and contacts the side guide wheel 4, the rubber debris on the side of the rubber sheet will be pressed into the inner groove 42 and detached from the rubber sheet. A chip discharge groove 14 is also provided in the rubber baffle plate 1. When the side guide wheel 4 rotates, the rubber debris in the inner groove 42 will contact the rubber guide wheel 61 and fall into the chip discharge groove 14, thereby completing the cleaning and collection of the rubber debris particles on the side of the rubber sheet, avoiding the problem of uneven side caused by cooling of the sticky debris particles when the rubber sheet is output.

[0056] The rubber wheel 61 is in a state of being pressed against the guide wheel 4 by the rubber tapping wheel 3. The rubber wheel 61 is in a state of being pressed against the guide wheel 4 by the rubber tapping wheel 3.

[0057] As another embodiment provided by the present invention, a reset assembly 7 is provided on the support rod 22, which includes a connecting sleeve 71, a movable sleeve 72 and a volute spring 73, the inner ring end of the volute spring 73 is fixedly connected to the movable cavity 223 of the support rod 22, the movable sleeve 72 is fixedly connected to the outer ring end of the volute spring 73, the movable sleeve 72 is axially slidably connected to the connecting sleeve 71, and the connecting sleeve 71 is coaxially fixedly connected to the locking member 6.

[0058] Specifically, Fig. 9 The cam 72 is engaged with the latch 22 and the latch 22 is engaged with the latch 22, and the latch 22 is, therefore the cam 72 is in a state of being moved in a direction of rotation as far as possible. The sleeve 71 slides axially to the closest position relative to the movable sleeve 72. At this time, if the rubber sheet is completely transported, the lateral guide wheel 4 is no longer pushed to rotate, so that the rubber wheel 61 is no longer subjected to the rotational thrust. The volute spring 73 drives the movable sleeve 72 through the connecting sleeve 71 to drive the locking member 6 to rotate in the opposite direction while sliding axially in the opposite direction to reset to the default position. The connecting sleeve 71, the movable sleeve 72 and the volute spring 73 of the reset assembly 7 are used to realize that the locking member 6 is automatically reset to the default state when no force is applied, so as to facilitate the continuous operation of the device and facilitate the subsequent automatic operation locking.

[0059] As another embodiment provided by the present invention, the transmission assembly 8 also includes a first transmission gear 82, a second transmission gear 83 and a third transmission gear 84. The ring gear seat 81, the first transmission gear 82, the second transmission gear 83 and the third transmission gear 84 are sequentially coupled in transmission, and the third transmission gear 84 is coupled to the rack portion 511 set on the base 51.

[0060] Specifically, Figure 7 As shown, the transmission assembly 8 also includes a first transmission gear 82, a second transmission gear 83 and a third transmission gear 84, the ring gear seat 81 is coupled to the first transmission gear 82, the first bevel gear portion 821 of the first transmission gear 82 is coupled to the second bevel gear portion 831 of the second transmission gear 83, and the second transmission gear 83 is coupled to the third transmission gear 84, and a matching groove 12 is opened on the rubber baffle plate 1, one side of the third transmission gear 84 extends out of the matching groove 12 to match with the rack portion 511 on the base 51, so that when the rubber baffle plate 1 is driven to slide relatively, the rack portion 511, the third transmission gear 84, the second transmission gear 83, the first transmission gear 82 and the ring gear seat 81 are used to realize the rotation drive of the mounting seat 21, thereby improving the driving stability when the rubber baffle plate 1 moves to drive the mounting seat 21 to rotate.

[0061] The gear ring seat 81 is further provided with a matching portion 812 , which is slidably disposed between the axial sliding grooves 212 of the mounting seat 21 to improve the axial sliding stability of the gear ring seat 81 .

[0062] As another embodiment provided by the present invention, it also includes an elastic member 813, and an extension groove 211 for extending the locking end 62 is opened on the mounting seat 21. The ring gear seat 81 is axially slidably arranged on the mounting seat 21, and a push block 91 is slidably arranged in the extension groove 211. The elastic member 813 pushes the ring gear seat 81 to be in a default state so that the ring gear seat 81 is coupled with the first transmission gear 82, and the thrust portion 811 arranged on the ring gear seat 81 enters the extension groove 211 to squeeze the push block 91 to radially limit the locking end 62. The support rod 22 is compressed to drive the locking member 6 to move radially to drive the push block 91 to slide. The thrust portion 811 is compressed to make the ring gear seat 81 slide to decouple from the first transmission gear 82, and the mounting seat 21 releases the rotation lock.

[0063] Specifically, Figure 5 As shown, the push block 91 is slidably disposed in the extension groove 211 of the mounting seat 21, and when the support rod 22 extends out of the mounting seat 21 to squeeze the rubber bearing block 23, the locking member 6 is still in the default state so that the locking end 62 does not extend into the extension groove 211. Figure 5As shown, at this time, the thrust portion 811 enters the extending groove 211 to squeeze the push block 91 to radially limit the locking end 62. If the support rod 22 of the lateral guide wheel 4 extends out of the supporting blade portion 32 and drives the locking member 6 to rotate so that the locking end 62 contacts the rubber baffle plate 1 through the extending groove 211, the mounting seat 21 and the rubber baffle plate 1 are locked by the end of the locking end 62, and the push block 91 radially limits the locking end 62, thereby realizing the locking of the locking member 6 and the support rod 22 relative to the mounting seat 21, thereby improving the supporting stability of the support rod 22.

[0064] However, when the cutting edge of the rubber tapping knife 3 cuts a rubber sheet with a smaller thickness, the cutting pressure on the front section of the cutting edge is smaller and the volume of the rubber waste removed is smaller, which makes it easy for the front end of the cutting edge to accumulate material due to the adhesion of rubber, so that the cutting pressure on the front section of the cutting edge gradually increases. The continuous accumulation of material on the front section of the cutting edge may cause the blade 32 of the rubber tapping knife 3 to collapse due to excessive cutting pressure.

[0065] Since the elastic member 813 is used to push the bearing portion 811 of the ring gear seat 81 to lock the push block 91 and the locking member 6, and the push portion 811 and the push block 91 are both provided with contacting inclined guide slopes, when material gradually accumulates on the blade portion of the rubber tapping knife 3 and the pressure on the blade portion 32 increases, the support rod 22 is subjected to the pressure of the blade portion 32 to drive the locking member 6 to squeeze the push block 91 to slide, and the push block 91 slides to squeeze the bearing portion 811 to compress the elastic member 813 to slide, so that the ring gear seat 81 can slide axially and decouple from the first transmission gear 82, and at this time, the locking member 6 slides until it no longer contacts the lateral guide wheel 4, and the connecting sleeve 71, movable sleeve 72 and worm spring 73 of the reset assembly 7 will drive the locking member 6 to slide and reset to the default state.

[0066] During the process of the locking member 6 sliding back to the default state, the locking end 62 no longer performs rotational locking on the mounting seat 21, but the locking end 62 is still located in the extension groove 211 to squeeze the push block 91, so that the ring gear seat 81 is still decoupled from the first transmission gear 82. At this time, the mounting seat 21 is rotated and unlocked, and the front end of the cutting edge of the rubber tapping knife 3 on the mounting seat 21 is under greater pressure due to the accumulated material, so that the mounting seat 21 is rotated under the action of the cutting pressure to adjust the vertical rotation lifting angle of the rubber tapping knife 3, so as to reduce the angle between the cutting edge of the rubber tapping knife 3 and the rubber sheet, that is, the cutting edge of the rubber tapping knife 3 is no longer perpendicular to the running direction of the rubber sheet, so that the rubber sheet can drive the accumulated material on the cutting edge to be pushed out of the rubber tapping knife 3 by friction during the movement, so as to clean the accumulated material on the cutting edge. Due to the discharge of the accumulated material on the cutting edge, the pressure on the support rod 22 is reduced, such as Figure 2As shown, since the lateral guide wheel 4 is arranged on the upper side of the axis of the mounting seat 21, the lateral guide wheel 4 contacts the rubber wheel 61 of the locking member 6 again, so that the lateral guide wheel 4 will apply a force to the mounting seat 21 to rotate and reset to the default state, and drive the mounting seat 21 to rotate to the default state so that the blade of the rubber tapping knife 3 is perpendicular to the rubber plate again, and then the lateral guide wheel 4 pushes the rubber wheel 61 to rotate to drive the locking end 62 to contact the inside of the rubber baffle 1 again to lock the mounting seat 21. At the same time, the elastic member 813 also drives the ring gear seat 81 to reset to the default state, so that the ring gear seat 81 is coupled to the first transmission gear 82 again. Therefore, when material accumulates at the front end of the tapping knife 3 by utilizing the push block 91, the gear ring seat 81 and the elastic member 813, the mounting seat 21 rotates internally to drive the tapping knife 3 to rotate and lift vertically to rub and clean the accumulated material, and then drives the tapping knife 3 to reset to continue stable cutting, thereby avoiding the problem of continuous accumulation of material on the blade of the tapping knife 3 causing the tapping knife 3 to collapse.

[0067] When the cutting edge of the rubber tapping knife 3 cuts the rubber sheet with a larger thickness, the mounting seat 21 is rotated and locked to the vertically inclined state of the rubber tapping knife 3, so that the cutting edge of the blade body 32 has an angle with the advancing direction of the rubber sheet. The cutting pressure on the rubber tapping knife 3 is relatively large due to the excessive cutting thickness. The support rod 22 is subjected to the pressure of the blade body 32 and drives the locking member 6 to squeeze the push block 91 to slide. The push block 91 slides to squeeze the push bearing portion 811 and compress the elastic member 813 to slide, so that the gear ring seat 81 can slide axially and decouple from the first transmission gear 82. At this time, the sliding of the locking member 6 is no longer in contact with the lateral guide wheel 4. The connecting sleeve 71, the movable sleeve 72 and the spiral spring 73 of the reset assembly 7 will drive the locking member 6 to slide and reset to the default state. During the sliding reset of the locking member 6 to the default state, the locking end 62 no longer rotates and locks the mounting seat 21, but the locking end 62 is still located in the extension groove 211 to squeeze the push block 91, even if the locking member 6 is The gear ring seat 81 is still decoupled from the first transmission gear 82. At this time, the mounting seat 21 rotates and unlocks. The front end of the cutting edge of the rubber tapping knife 3 on the mounting seat 21 is under great pressure due to the accumulation of material, so that the mounting seat 21 rotates under the action of the cutting pressure to adjust the vertical rotation and lifting angle of the rubber tapping knife 3, thereby further reducing the angle between the cutting edge of the rubber tapping knife 3 and the rubber plate, reducing the cutting pressure on the rubber tapping knife 3, and then the pressure on the support rod 22 is reduced, and the lateral guide wheel 4 contacts the rubber wheel 61 of the locking member 6 again, and drives the mounting seat 21 to rotate to the default state so that the cutting edge of the rubber tapping knife 3 is perpendicular to the rubber plate again, and then the lateral guide wheel 4 pushes the rubber wheel 61 to rotate to drive the locking end 62 to contact the inside of the rubber baffle plate 1 again to lock the mounting seat 21. At the same time, the elastic member 813 also drives the gear ring seat 81 to reset to the default state, so that the gear ring seat 81 is coupled with the first transmission gear 82 again, thereby locking the rotation of the mounting seat 21. Furthermore, the push block 91, the gear ring seat 81 and the elastic member 813 are used to realize that when the cutting pressure on the rubber tapping knife 3 is too large, the mounting seat 21 can be unlocked and rotated to further reduce the angle between the blade of the rubber tapping knife 3 and the rubber sheet and then rotated and locked, so that the rubber tapping knife 3 is in a non-vertical state, and the mounting seat 21 rotates to automatically adjust the angle between the blade of the rubber tapping knife 3 and the rubber sheet according to the cutting pressure, thereby avoiding damage to the rubber tapping knife 3.

[0068] Working principle: when the cutting blade of the rubber tapping knife 3 cuts the rubber sheet with a smaller thickness, the mounting seat 21 is located in the default position so that the cutting blade of the rubber tapping knife 3 is perpendicular to the rubber sheet, that is, the rubber sheet is transported horizontally and advanced, and the blade portion 32 of the rubber tapping knife 3 is vertical so that the cutting blade faces both sides of the rubber sheet for cutting operation, and the rubber sheet is moved and transported to push the lateral guide wheel 4 to rotate axially, and the lateral guide wheel 4 pushes the support rod 22 to slide out of the mounting seat 21 to squeeze the rubber bearing block 23, and the support rod 22 slides so that the rubber wheel 61 of the locking member 6 moves to be aligned with the driving portion 41, and as the lateral guide wheel 4 continues to rotate, the driving portion 41 will continuously squeeze and push the rubber wheel 61 to rotate, thereby causing the locking member 6 to rotate and move axially, and at this time, the rubber wheel 61 moves axially toward the lateral guide wheel 4 while rotating, until the locking end 62 of the locking member 6 moves axially out of the outer side of the mounting seat 21 to contact the rubber baffle plate 1, thereby realizing the locking of the mounting seat 21 and the support rod 22;

[0069] When material gradually accumulates on the blade of the rubber tapping knife 3 and the pressure on the blade body 32 increases, the support rod 22 is pressed by the blade body 32 to drive the locking member 6 to squeeze the push block 91 to slide, and the push block 91 slides to squeeze the push portion 811 and compress the elastic member 813 to slide, so that the ring gear seat 81 can slide axially and decouple from the first transmission gear 82, and at this time, the sliding of the locking member 6 to the lateral guide wheel 4 is no longer in contact, and the connecting sleeve 71, the movable sleeve 72 and the worm spring 73 of the reset assembly 7 will drive the locking member 6 to slide and reset to the default state, and the locking end 62 squeezes the push block 91, so that the ring gear seat 81 is still decoupled from the first transmission gear 82, and the mounting seat 21 is rotated to unlock, and the mounting seat 21 is unlocked. The front end of the cutting edge of the rubber tapping knife 3 is under great pressure due to the accumulated material, so that the mounting seat 21 is rotated under the action of the cutting pressure to adjust the vertical rotation and lifting angle of the rubber tapping knife 3, thereby reducing the angle between the cutting edge of the rubber tapping knife 3 and the rubber plate. During the movement, the rubber plate can drive the accumulated material on the cutting edge to be pushed out of the rubber tapping knife 3 by friction, and then the lateral guide wheel 4 contacts the rubber wheel 61 of the locking member 6 again, driving the mounting seat 21 to rotate to the default state so that the cutting edge of the rubber tapping knife 3 is perpendicular to the rubber plate again, and then the lateral guide wheel 4 pushes the rubber wheel 61 to rotate to drive the locking end 62 to contact the inside of the rubber baffle plate 1 again to lock the mounting seat 21, and the gear ring seat 81 is coupled to the first transmission gear 82 again;

[0070] The rubber baffle plate 1 can also be driven by the threaded rod 52 to slide relatively, and the rubber tapping knife 3 moves relatively close to increase the cutting thickness of the rubber plate. At the same time, the rack portion 511, the third transmission gear 84, the second transmission gear 83, the first transmission gear 82 and the ring gear seat 81 are used to realize the rotation drive of the mounting seat 21. The rubber tapping knife 3 on the mounting seat 21 rotates vertically with the rotation of the mounting seat 21, so that the blade of the rubber tapping knife 3 is rotated and lifted, and the vertical angle between the rubber tapping knife 3 and the rubber plate is reduced, thereby reducing the extrusion deformation force on the blade body 32.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
