Description

Technical Field

[0001] The invention relates to the technical field of tire recycling equipment, and in particular to a tire strip cutting device. Background Art

[0002] At present, with the progress of society and the development of economy, various vehicles have become indispensable consumables in people's production and life. Among them, tires are especially high consumables, and a large number of tires are replaced every year. Therefore, the recycling and reuse of tire resources has become an indispensable link in the automotive industry chain.

[0003] The treatment of waste tires generally includes the following process: breaking the tires into small pieces, then grinding the small pieces of tires, and then sorting and recycling them. The final recycled products mainly include rubber, steel wires and fibers embedded in the rubber, etc.

[0004] Therefore, how to divide the whole tire into small pieces for subsequent recycling has become the primary problem to be solved in the entire tire recycling process. In order to cut the waste tires into pieces, the waste tire processing equipment previously applied for by the applicant provides an implementation scheme, which uses an interlocking double-axis machine to tear the tires into small pieces. However, the applicant found in the specific implementation of the scheme that the equipment is relatively large and requires a relatively large installation site for equipment installation. At the same time, its efficiency can only be demonstrated when processing in large quantities. If the processing volume is relatively small, its power consumption is significantly higher. At the same time, the equipment cost is also relatively high, which is not suitable for the needs of small factories and small batch processing.

DETAILED DESCRIPTION

[0032] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0033] like Figure 1-4A tire strip cutting device shown includes a fixed frame 10, a cutter assembly 20, a circular cutter disc driving mechanism 30, a material receiving frame 40 and a material receiving frame driving mechanism 60. Specifically, the cutter assembly 20 includes a first circular cutter disc 21 and a second circular cutter disc 22 pivotally connected to the fixed frame 10 respectively; the first circular cutter disc 21 and the second circular cutter disc 22 are arranged vertically, and the blades of the first circular cutter disc 21 and the second circular cutter disc 22 intersect and fit each other; in a preferred embodiment, a pressing mechanism can be provided, and the pressing mechanism can be connected to the first circular cutter disc 21 or the second circular cutter disc 22, so as to drive the first circular cutter disc 21 and the second circular cutter disc 22 to fit tightly. In one embodiment, the pressing mechanism is coaxially arranged with the first circular cutter disc 21 and drives the first circular cutter disc 21 to press tightly against the second circular cutter disc 22. The pressing mechanism can adopt any structure that can achieve the above functions, which is not limited here, such as using a compression spring or using magnetic force. The receiving rack 40 is provided with a receiving post 50; the receiving post 50 is used for matching the tire bead, and the bead can rotate around the receiving post 50 under the drive of other forces. In a preferred embodiment, the receiving post 50 can rotate relative to the receiving rack 40 around the central axis of the receiving post 50, so that the receiving post 50 and the bead can rotate synchronously or approximately synchronously, reducing the sliding friction between the receiving post 50 and the bead, thereby reducing the wear of the receiving post 50. The receiving rack 40 is installed on the fixed rack 10 and can rotate relative to the fixed rack 10 around the horizontal axis; the receiving rack 40 is used to transport the bead placed on the receiving post 50 to the cutter assembly 20, so that the cutter assembly 20 completes the cutting of the bead and cuts the bead into a long strip of bead. Therefore, the receiving rack 40 can rotate around the rotation axis on the fixed rack 10 within a certain range. That is, it can be set to a loading position and a cutting position. The receiving frame 40 rotates between the loading position and the cutting position around the rotating shaft set on the fixed frame 10 under the drive of the receiving drive device. The loading position can be a position where the central axis of the receiving column 50 is perpendicular to the circular blade surface of the first circular blade disc 21, or it can be a position between the position where the central axis of the receiving column 50 is perpendicular to the circular blade surface of the first circular blade disc 21 and the cutting position. The loading position satisfies that when the tire bead is placed on the receiving column 50, the outer tread of the tire bead will not touch the cutter assembly 20, and the tire bead will not fall from the receiving column 50. The cutting position satisfies that the outer tread of the tire bead can be engaged by the first circular blade disc 21 and the second circular blade disc 22 of the cutting assembly and the tire bead is cut into strips.

[0034] In addition, the circular cutter disc driving mechanism 30 is used to drive the first circular cutter disc 21 and the second circular cutter disc 22 to rotate, and the rotation directions of the first circular cutter disc 21 and the second circular cutter disc 22 are opposite, that is, Figure 6 As shown, the first circular cutter disc 21 rotates clockwise, and the second circular cutter disc 22 rotates counterclockwise, so that the cutting directions of the first circular cutter disc 21 and the second circular cutter disc 22 are the same, both as shown in FIG. Figure 6The direction indicated by arrow G can be used to cut the tire; the material receiving rack driving mechanism 60 is used to drive the material receiving rack 40 to rotate.

[0035] On the basis of the above structure, the receiving rack driving mechanism 60 drives the receiving rack 40 to rotate until the receiving post 50 is in the loading position. At this time, the bead of half of the tire can be mounted on the receiving post 50, and the side of the tire without the bead is facing upwards. The receiving rack driving mechanism 60 drives the receiving rack 40 to link the receiving post 50 to rotate to a horizontal state. During this process, the tire on the receiving post 50 is also gradually approaching the first circular cutter disc 21 and the second circular cutter disc 22 on the fixed frame 10. In this way, the outermost part of the tire can enter between the blades of the first circular cutter disc 21 and the second circular cutter disc 22 during the rotation process, and the circular cutter disc driving mechanism 30 drives the first circular cutter disc 21 and the second circular cutter disc 22 to rotate in opposite directions. During the rotation process, the first circular cutter disc 21 and the second circular cutter disc 22 can start cutting from the outermost periphery of the tire. The first circular blade disc 21 and the second circular blade disc 22 cooperate with each other to bite the tire during the cutting process, thereby driving the tire-linked material receiving column 50 to rotate relative to the material receiving frame 40, or an external force is used to drive the material receiving column 50 to rotate relative to the material receiving frame 40, so that the other parts of the outer circumference of the tire are continuously transported between the blades of the first circular blade disc 21 and the second circular blade disc 22, thereby realizing the full circle cutting of the outermost circumference of the tire, and as the material receiving column 50 continuously approaches the fixed frame 10 and rotates, the tire is gradually squeezed between the first circular blade disc 21 and the second circular blade disc 22. When the material receiving column 50 is completely horizontal, the tire is cut, that is, the tire strip cutting operation is completed. In this way, the tire strip cutting operation can be realized in coordination with the motor, and the tire can be cut into long strips quickly and efficiently, so as to facilitate the subsequent cutting of the tire into small pieces, thereby realizing the resource recycling of the tire.

[0036] Furthermore, the material receiving column 50 includes a base plate 51 and a cylinder 52 fixed on the base plate 51. Specifically, when the material receiving column 50 is in a vertical state, the cylinder 52 is located above the base plate 51; the cylinder 52 is used for matching the tire bead; the base plate 51 has an abutment portion extending out of the outer surface of the cylinder 52. It should be noted here that the outer surface of the cylinder 52 refers to the curved surface of the cylinder 52 facing the outside; the abutment portion is used to abut against the tire to prevent the tire from detaching from the cylinder 52 when the tire is mounted outside the cylinder 52.

[0037] More specifically, the cross-section of the bottom plate 51 is circular; the bottom plate 51 is coaxially arranged with the cylinder 52, and the diameter of the bottom plate 51 is larger than the outer diameter of the cylinder 52, so that the bottom plate 51 has a portion that uniformly extends out of the outer periphery of the cylinder 52, and this portion is the abutment portion, achieving comprehensive abutment with the tire.

[0038] Furthermore, the material receiving rack driving mechanism 60 can be implemented by a cylinder. Specifically, the cylinder body of the cylinder is hinged on the fixed frame 10, and the telescopic rod of the cylinder is hinged on the material receiving rack 40; of course, the above-mentioned material receiving rack driving mechanism 60 can also adopt a rotating motor, and the output shaft of the rotating motor is transmission-connected to the material receiving rack 40, and the central axis of the output shaft of the rotating motor coincides with the pivot axis of the material receiving rack 40.

[0039] The above-mentioned circular cutter disc drive mechanism 30 can be implemented in the following manner: the circular cutter disc drive mechanism 30 includes a rotating motor, a driving gear fixedly connected to the first circular cutter disc 21, and a passive gear fixedly connected to the second circular cutter disc 22. Specifically, the output shaft of the rotating motor is transmission-connected to the first circular cutter disc 21, and the driving gear and the passive gear are meshed. However, the driving gear and the passive gear are vulnerable parts and are easily damaged.

[0040] The circular cutter disc drive mechanism 30 mentioned above may also preferably be implemented in the following manner: the circular cutter disc drive mechanism 30 comprises a first rotary motor 31 and a second rotary motor 32; the body of the first rotary motor 31 is mounted on the fixed frame 10, and the output shaft of the first rotary motor 31 is transmission-connected to the first circular cutter disc 21; the body of the second rotary motor 32 is mounted on the fixed frame 10, and the output shaft of the second rotary motor 32 is transmission-connected to the second circular cutter disc 22. At this time, by controlling the rotation direction of the rotation shafts of the first rotary motor 31 and the second rotary motor 32, the rotation direction of the first circular cutter disc 21 and the second circular cutter disc 22 can be controlled; here, by using the first rotary motor 31 and the second rotary motor 32 to drive separately, there is no problem of damage to wearing parts such as gears; on the other hand, under the condition of equal energy consumption, since the first rotary motor 31 and the second rotary motor 32 are used to drive separately, the energy loss generated by the intermediate driving gear and the passive gear during the transmission process can be omitted, and the driving force of the first rotary motor 31 and the second rotary motor 32 to drive separately is greater and the energy loss is smaller.

[0041] Furthermore, the tire strip cutting device also includes a toggle gear 70; the toggle gear 70 can be rotatably mounted on the fixed frame 10 around its central axis; when the toggle gear 70 rotates, the tooth portion of the toggle gear 70 can toggle the tire on the material receiving column 50 so that the tire rotates around the central axis of the material receiving column 50 relative to the first circular cutter disc 21 and the second circular cutter disc 22; the circular cutter disc driving mechanism 30 is also used to drive the toggle gear 70 to rotate when driving the first circular cutter disc 21 and the second circular cutter disc 22 to rotate; in this way, part of the tire enters between the first circular cutter disc 21 and the second circular cutter disc 22, and during the cutting process of the cutter assembly 20, the toggle gear 70 toggle the tire to rotate, and during the rotation of the tire, the first circular cutter disc 21 and the second circular cutter disc 22 cooperate to cut the circumference of the tire. At this time, the toggle gear 70 can replace manpower, or, on the basis of the first circular cutter disc 21 and the second circular cutter disc 22 cooperating to bite the tire, further, ensure that the tire continues to rotate circumferentially relative to the cutter assembly 20, that is, ensure circumferential cutting of the gear.

[0042] Specifically, the toggle gear 70 is fixedly connected to the second circular cutter disc 22 and is coaxially arranged, so that when the circular cutter disc driving mechanism 30 drives the second circular cutter disc 22, the toggle gear 70 can be rotated.

[0043] It is worth mentioning that the teeth of the shifting gear 70 extend along the rotation direction of the second circular cutter disc 22, further ensuring the shifting of the tire.

[0044] In order to realize the transmission connection between the first circular cutter disc 21 and the circular cutter disc driving mechanism 30, here, the first circular cutter disc 21 includes a cutter disc body 211, a blade disc body 212 and a locking structure 231; the locking structure 231 is used to fix the cutter disc body 211 and the blade disc body 212 in connection; the blade disc body 212 is coaxially arranged with the cutter disc body 211, and the blade of the blade disc body 212 protrudes out of the cutter disc body 211; the circular cutter disc driving mechanism 30 is transmission-connected with the cutter disc body 211, so that the strength of the blade disc body 212 can be enhanced through the cutter disc body 211, and the direct connection between the blade disc body 212 and the circular cutter disc driving mechanism 30 to damage the structure of the blade disc body 212 can be avoided.

[0045] It should be noted that the diameter of the blade disc body 212 is greater than the diameter of the blade seat disc body 211 , so as to ensure that the blade of the blade disc body 212 protrudes out of the blade disc body 212 .

[0046] Furthermore, the positioning structure 80 includes a positioning block 81 and a positioning groove 82; one of the positioning block 81 and the positioning groove 82 is arranged on the tool seat disc body 211, and the other is arranged on the blade disc body 212; the positioning groove 82 and the positioning block 81 are matched and inserted so that the central axes of the tool seat disc body 211 and the blade disc body 212 coincide with each other. At this time, the coaxial setting of the tool seat disc body 211 and the blade disc body 212 is achieved, and there is no need to manually judge the coaxiality of the tool seat disc body 211 and the blade disc body 212 with the naked eye and perform multiple position adjustments, thereby simplifying the installation procedure of the first circular tool disc 21.

[0047] The present invention discloses a further implementation of the positioning structure 80, specifically, the positioning groove 82 is opened on the blade disc body 212, and the positioning block 81 is arranged on the blade seat disc body 211; more specifically, the positioning groove 82 is coaxially arranged with the blade disc body 212, and the positioning block 81 body and the blade seat disc body 211 are coaxially arranged, so that after the positioning groove 82 body is inserted into the positioning seat, the blade disc body 212 and the blade seat disc body 211 are coaxially arranged; of course, the positioning structure 80 can also adopt the following implementation mode, specifically, the positioning groove 82 is opened on the blade seat disc body 211, and the positioning block 81 is arranged on the blade disc body 212; more specifically, the positioning groove 82 is coaxially arranged with the blade seat disc body 211, and the positioning block 81 and the blade disc body 212 are coaxially arranged.

[0048] The present invention also discloses another embodiment of the positioning structure 80, wherein the positioning block 81 is a non-equilateral right triangle or other irregular shapes, etc., and the positioning groove 82 is also a non-equilateral right triangle or other irregular shapes, etc. having the same shape as the positioning block 81. In this way, by matching the positioning groove 82 and the positioning, the relative positioning of the blade disc body 212 and the blade seat disc body 211 can be achieved, thereby achieving the coaxial setting of the two.

[0049] Specifically, the locking structure 231 includes a first socket 2311 provided on the knife seat disc body 211, a second socket 2312 provided on the blade disc body 212, a screw and a nut; wherein the rod of the screw passes through the first socket 2311 and the second socket 2312 and is threadedly engaged with the nut, thereby locking the knife seat disc body 211 and the blade disc body 212. At this time, the knife seat disc body 211 and the blade disc body 212 can be replaced by unscrewing the screw and the nut.

[0050] More specifically, the blade disc body 212 is recessed on one side away from the blade seat disc body 211 toward the direction close to the blade seat disc body 211 to form a receiving groove 90; the second insertion hole 2312 is opened at the bottom of the receiving groove 90, and the positioning groove 82 is opened at the bottom of the receiving groove 90; the head of the screw is located in the receiving groove 90, and the thickness of the head of the screw is less than or equal to the depth of the receiving groove 90, so that the head of the screw is prevented from protruding out of the blade disc body 212, thereby preventing the head of the screw from scraping other working equipment or operators during operation.

[0051] Furthermore, the receiving groove 90 and the positioning groove 82 are coaxially arranged.

[0052] Since the tire contains materials with relatively high hardness such as steel wire, preferably, the blade disc body 212 is in a truncated cone shape; the upper bottom surface of the blade disc body 212 faces the blade seat disc body 211; Figure 3 As shown, the angle ∠A between the lower bottom surface of the blade disc body 212 and the side surface of the blade disc body 212 is 40-50°, and a blade edge is formed at the intersection of the lower bottom surface of the blade disc body 212 and the side surface of the blade disc body 212. Specifically, the angle is preferably 44.5°. At this time, the blade edge of the blade disc body 212 is relatively sharp, and the thickness of the blade disc body 212 is sufficient, thereby avoiding the blade from being broken by materials such as cutting wire.

[0053] The tire strip cutting device also includes a protective cover 110, which is fixed on the body of the motor, and a gap cover is arranged outside the knife seat disc body 211 and the blade disc body 212. It can be understood that there are gaps between the protective cover 110 and the knife seat disc body 211 and the blade disc body 212 to avoid cutting the protective cover 110 during the rotation of the blade disc body 212, and the blade of the blade disc body 212 extends out of the protective cover 110; in this way, the setting of the protective cover 110 separates the cutter assembly 20, thereby reducing the possibility of accidental cutting.

[0054] It is worth mentioning that the second circular cutter disc 22 may also adopt a structure in which a cutter seat and a blade cooperate, wherein the cutter disc and the blade may be coaxially arranged through the insertion and cooperation of a positioning cavity and a positioning plug block; further, the blade is in a truncated cone shape; Figure 4 As shown, the angle ∠B between the lower bottom surface of the blade and the side surface of the blade is 40-50°, and the intersection of the lower bottom surface of the blade and the side surface of the blade forms a blade edge. Specifically, the angle A is preferably 48°.

[0055] Further, the surface tangent to the first circular cutter disc 21 and the second circular cutter disc 22 forms a first cut surface 120; here, the first cut surface 120 is the lower bottom surface of the blade disc body 212; the surface tangent to the first and second circular cutter discs 22 and the first circular cutter disc 21 forms a second cut surface; at this time, the first circular cutter disc 21 and the second circular cutter disc 22 can adopt the following first embodiment: the first cut surface 120 and the second cut surface can be set to have equal diameters, and in the horizontal direction parallel to the first cut surface 120, the center of the first cut surface 120 and the center of the second cut surface coincide with each other, such as Figure 5 As shown, the angle ∠D formed at the intersection of the first circular cutter disc 21 and the second circular cutter disc 22, at this time, the edges of the first circular cutter disc 21 and the second circular cutter disc 22 are flush, and the edges of the first circular cutter disc 21 and the second circular cutter disc 22 are simultaneously against the tire, which is not conducive to the tire entering between the two, that is, it is not conducive to the tire entering the angle ∠D; the first circular cutter disc 21 and the second circular cutter disc 22 can adopt the following second embodiment: preferably, the diameter of the first section 120 is greater than the diameter of the second section; in the horizontal direction parallel to the first section 120 (such as Figure 6 In the direction indicated by arrow F), the center of the first section 120 and the center of the second section are offset from each other. Figure 6 As shown, the intersection of the first circular cutter disc 21 and the second circular cutter disc 22 forms an angle ∠E. At this time, the edges of the right sides of the first circular cutter disc 21 and the second circular cutter disc 22 are staggered, and the first circular cutter disc 21 first contacts the tire and pushes the tire downward to contact the second circular cutter disc 22, thereby facilitating the tire to enter the right side of the first circular cutter disc 21 and the second circular cutter disc 22, that is, within the angle ∠E, and is easy to cut.

[0056] When the first circular blade disc 21 and the second circular blade disc 22 initially cut the tire, the tire does not engage with the first circular blade disc 21 and the second circular blade disc 22 at the beginning. At this time, the tire is prone to sinking under the impact of the first circular blade disc 21 and the second circular blade disc 22, which makes the initial cutting difficult. Therefore, the tire slitting device also includes a pressing mechanism 100, which is used to push the tire so that the tire tread entering between the first circular blade disc 21 and the second circular blade disc 22 is close to the blade of the first circular blade disc 21 or the blade of the second circular blade disc 22. In this way, when the first circular blade disc 21 or the second circular blade disc 22 rotates, the tire tread is close to the first circular blade disc 21 or the second circular blade disc 22. At this time, the first circular blade disc 21 and the second circular blade disc 22 can smoothly cut into the tire, thereby facilitating the subsequent engagement of the tire.

[0057] Specifically, the pressing mechanism 100 includes a telescopic cylinder 101, a bending arm 102 and a pressing head 103; the cylinder body of the telescopic cylinder 101 is hinged on the fixed frame 10, the telescopic rod of the telescopic cylinder 101 is hinged on one end of the bending arm 102, and the middle part of the bending arm 102 is hinged on the fixed frame 10; the pressing head 103 is installed at the other end of the bending arm 102; the pressing head 103 is used to push the tire, so that the pressing head 103 is extended between the tire and the receiving column 50, and the telescopic rod of the telescopic cylinder 101 is extended and retracted to drive the bending arm to rotate around the hinge point in the middle thereof.
