Description

Technical Field

[0001] The invention belongs to the technical field of rubber roller production, in particular to an automatic cutting device for rubber roller production. Background Art

[0002] A rubber roller is a roll-shaped product made of metal or other materials as the core and rubber covered by vulcanization. The processing of rubber rollers includes sandblasting of the roller core, bonding, rubber forming, cloth wrapping, wire winding, vulcanization in a vulcanizer, surface processing and cutting. The purpose of cutting the rubber roller is to cut off the rubber that exceeds the end of the roller core so that the rubber and the roller core remain flush.

[0003] In the prior art, when cutting off the rubber portion of the rubber roller that exceeds the end of the rubber roller core, it is necessary to adjust the position of the rubber roller to ensure that the end face of the rubber roller core is flush with the cutting mechanism, and then drive the rubber roller to move toward the cutting mechanism, and use the cutting mechanism to cut off the excess rubber. This cutting method is relatively traditional. After the rubber roller is covered with rubber, the length of each rubber roller core end that exceeds the rubber will be different. This will result in the need to pre-adjust the relative position between the rubber roller and the cutting mechanism when cutting different rubber rollers, resulting in relatively low cutting efficiency.

A plurality of rubber rollers to be cut are placed on the upper portion of the support ramp 10. The limit baffle 60 vertically penetrates the support ramp 10 and can move up and down relative to the support ramp 10. The limit baffle 60 is used to limit the plurality of rubber rollers. The bracket plate 20 is arranged on the outer side of the support ramp 10. The cutting assembly 40 is provided with two groups. The two groups of cutting assemblies 40 are arranged on the inner side of the bracket plate 20 and are located at the front and rear sides of the support ramp 10. On the side, the first driving component 30 is installed on the side wall of the bracket plate 20, and is used to drive the two groups of the cutting components 40 to move away from and approach each other. When the two groups of the cutting components 40 approach each other, they respectively contact the roller cores at both ends of the lowest rubber roller. The second driving component 50 is provided with two groups, and the two groups of the second driving components 50 are respectively installed on the two groups of the cutting components 40. After the two groups of the cutting components 40 respectively contact the roller cores at both ends of the lowest rubber roller, the two groups of the second driving components 50 are used to drive the lowest rubber roller to rotate compared with the two groups of the cutting components 40. The third driving component 70 is arranged at the bottom of the supporting ramp 10, and is used to drive the limit baffle 60 to move up and down.

[0044] When it is necessary to cut off the excess rubber at both ends of several rubber rollers, several rubber rollers to be cut can be placed on the upper part of the supporting ramp 10 and several rubber rollers 10 can be arranged in sequence. At this time, the limit baffle 60 acts on one side of the lowest rubber roller, thereby limiting the position of several rubber rollers, and then the first driving component 30 is used to drive the two groups of cutting components 40 to move toward each other. When the two groups of cutting components 40 are in contact with the roller cores at both ends of the lowest rubber roller respectively, the second driving component 50 drives the lowest rubber roller to rotate compared with the two groups of cutting components 40, and the two groups of cutting components 40 are used to perform circular cutting on the rubber that exceeds the roller core of the rubber roller, so as to ensure that the rubber coated on the outside of the roller core is kept flush with the roller core, thereby completing the cutting operation of the current rubber roller; after the current rubber roller is cut, the first driving component 30 drives the two groups of cutting components 40 to move away from each other, and the two groups of cutting components 40 are separated from the roller core of the lowest rubber roller, and at the same time, the third driving component 70 drives the limit baffle 60 to move downward compared with the supporting ramp 10, thereby releasing For the limiting state of several rubber rollers, at this time, the lowest rubber roller rolls downward along the upper part of the supporting ramp 10 and rolls away from the bottom of the supporting ramp 10. After the lowest rubber roller rolls away from the bottom of the supporting ramp 10, the third driving assembly 70 drives the limiting baffle 60 to move upward compared with the supporting ramp 10, and then acts on the subsequent rubber roller below to limit the subsequent several rubber rollers again. Then, the first driving assembly 30 drives the two groups of cutting assemblies 40 to approach each other again. After the two groups of cutting assemblies 40 act on the two ends of the roller core of the rubber roller below, the second driving assembly 50 drives the rubber roller below to rotate compared with the two groups of cutting assemblies 40. The two groups of cutting assemblies 40 cut the rubber beyond the roller core at both ends of the rubber roller below again. Then, the first driving assembly 30 drives the two groups of cutting assemblies 40 away from each other again. The third driving assembly 70 drives the limiting baffle 60 downward again, so that the rubber roller below rolls away from the bottom of the supporting ramp 10... Such a reciprocating cycle can realize the continuous automatic cutting operation of several rubber rollers.

[0045] See also Figure 1 as well as Figure 2 In one embodiment, the first driving assembly 30 includes a slide plate 301, a first rotating shaft 302 and a motor 305, wherein the motor 305 is fixedly mounted on the side wall of the bracket plate 20, one end of the first rotating shaft 302 is connected to the output end of the motor 305, and the other end extends to the inner side of the bracket plate 20 and is rotatably connected to the inner wall of the bracket plate 20, two groups of threaded segments 303 with opposite rotation directions are arranged on the outside of the first rotating shaft 302, the slide plate 301 is provided with two groups, and the two groups of slide plates 301 are respectively arranged on the front and rear sides of the supporting ramp 10, the first rotating shaft 302 passes through the two groups of slide plates 301 and is threadedly matched with the two groups of slide plates 301 through the two groups of threaded segments 303, and the two groups of cutting assemblies 40 are respectively mounted on the opposite sides of the two groups of slide plates 301.

[0046] After the limit baffle 60 acts on one side of a group of rubber rollers and thus limits the position of several rubber rollers, the first rotating shaft 302 is driven to rotate by the motor 305, and the two groups of threaded segments 303 and the two groups of skateboards 301 cooperate with each other to drive the two groups of skateboards 301 to move toward each other along the length direction of the first rotating shaft 302, thereby driving the two groups of cutting components 40 to approach each other. When the two groups of cutting components 40 act on the roller cores at both ends of the rubber rollers in contact with the limit baffle 60 respectively, the second driving component 50 drives the rubber roller to rotate compared with the two groups of cutting components 40, and the two groups of cutting components 40 are used to perform ring cutting on the rubber at both ends of the rubber roller that exceeds the roller core. After the current rubber roller is cut, the motor 305 drives the first rotating shaft 302 to rotate in the opposite direction, and the two groups of threaded segments 303 and the two groups of skateboards 301 cooperate with each other to drive the two groups of skateboards 301 to move in the opposite direction. The two groups of skateboards 301 drive the two groups of cutting components 40 to move away from each other, and then separate from the roller cores of the rubber rollers respectively.

[0047] See also Figure 1 as well as Figure 2 In one embodiment, the first driving assembly 30 also includes a guide rod 304, which is fixedly disposed on the inner wall of the bracket plate 20, and the guide rod 304 is parallel to the first rotating shaft 301, and the guide rod 304 passes through the two groups of the slides 301 and movably cooperates with the two groups of the slides 301.

[0048] When the motor 305 drives the first rotating shaft 302 to rotate, through the active cooperation of the two sets of slides 301 and the guide rod 304, the two sets of threaded segments 303 can smoothly and stably drive the two sets of slides 301 to move along the length direction of the first rotating shaft 302, thereby stably driving the two sets of cutting components 40 to move away from and towards each other.

[0049] See also Figure 4 as well as Figure 5In one embodiment, the two groups of the second driving components 50 have the same structure, and both include a top support rod 501, a first elastic member 503 and a sleeve 504. One end of the sleeve 504 is fixedly connected to the slide plate 301, and the other end is sleeved on the outside of the top support rod 501 and movably cooperates with the top support rod 501. A protrusion 506 is fixedly provided on the inner wall of the sleeve 504. A spiral groove 505 is provided on the side wall of the rod body of the top support rod 501 located inside the sleeve 504. The protrusion 506 extends into the inside of the spiral groove 505 and can slide along the inside of the spiral groove 505. The top support rod 501 is fixed on the rod body outside the sleeve 504. A ring seat 502 is fixedly provided, one end of the first elastic member 503 is connected to the ring seat 502, and the other end is connected to the sleeve 504, which is used to provide elastic support for the top support rod 501. The two groups of cutting assemblies 40 have the same structure, both include cutters 401 and first support rods 402, and the cutters 401 are provided with several groups. Several of the cutters 401 are arranged on the outside of the top support rod 501 and are distributed in a ring-shaped interval with respect to the top support rod 501. One side of each group of the cutters 401 is hingedly provided with a group of the first support rods 402, and the end of each group of the first support rods 402 away from the corresponding cutter 401 is hingedly connected to the sleeve 504.

[0050] When the motor 305 drives the first rotating shaft 302 to rotate and then drives the two sets of slide plates 301 to move toward each other, the two sets of slide plates 301 drive the two sets of sleeves 504 and the two sets of top support rods 501 to move toward each other. When the two sets of sleeves 504 move toward each other, the plurality of cutters 401 are driven to move toward each other through the plurality of first support rods 402. When the two sets of top support rods 501 act on the two ends of the rubber roller core respectively, the plurality of cutters 401 are attached to the ends of the rubber roller core. As the two sets of slide plates 301 continue to move toward each other, the two sets of top support rods 501 are subjected to force and then The sleeve 504 moves inside, and at the same time, a plurality of cutters 401 are forced to fit the end of the roller core and slide toward the outside of the roller core. In this process, a plurality of cutters 401 pierce the rubber that exceeds the roller core from the inside to the outside along the radial direction of the roller core. A plurality of first support rods 402 are forced to deflect compared with the sleeve 504, and at the same time, the protrusion 506 slides inside the spiral groove 505, thereby pushing the top support rod 501 to rotate. When the two groups of top support rods 501 rotate, they clamp the roller core and drive the rubber roller to rotate together. The cutters 401 pierce the rubber that exceeds the roller core. The rubber is then cut in a circular manner with the help of the rotation of the rubber roller; when the plurality of cutters 401 have completed the circular cutting of the rubber that exceeds the roller core, the motor 305 drives the first rotating shaft 302 to rotate in the opposite direction, and the first rotating shaft 302 drives the two sets of slide plates 301 to move away from each other, thereby driving the two sets of sleeves 504 and the plurality of cutters 401 to move away from each other. When the two sets of sleeves 504 move away from each other, the first elastic member 503 pushes the two sets of support rods 501 so that the two sets of support rods 501 move toward the two sets of sleeves 504, respectively. 04 moves externally, at this time, the protrusion 506 slides in the opposite direction along the spiral groove 505, thereby driving the two groups of top support rods 501 to rotate in the opposite direction compared to the corresponding sleeves 504, thereby realizing the reset of the two groups of top support rods 501. When the two groups of top support rods 501 are reset, the two groups of sleeves 504 pull the two groups of top support rods 501 to separate the two groups of top support rods 501 from the end of the rubber roller core. At the same time, the two groups of sleeves 504 drive the multiple cutters 401 away from the end of the rubber roller core through the multiple first support rods 402, thereby realizing the reset of the multiple cutters 401.

[0051] In one embodiment, a rubber head is provided at one end of the two groups of top support rods 501 away from the corresponding sleeve 504. Through the setting of the rubber head, when the two groups of top support rods 501 act on the two ends of the roller core of the rubber roller respectively, the friction between the top support rods 501 and the roller core can be increased, so that when the two groups of top support rods 501 rotate, they can smoothly drive the rubber roller to rotate together, thereby achieving smooth ring cutting of the excess rubber.

[0052] In one embodiment, each group of the first support rods 402 is also connected to the sleeve 504 by a third elastic member (not shown in the figure), and the third elastic member is used to provide elastic pulling force to the first support rod 402. When the two groups of slides 301 move toward each other and push the plurality of cutters 401 to move outward in contact with the end of the rubber roller core, the plurality of second support rods 402 are adaptively deflected compared to the sleeve 504, thereby causing the third elastic member to adaptively stretch. After the rubber ring cutting of the portion exceeding the roller core is completed, as the two groups of sleeves 504 move away from each other, the sleeve 504 pulls the plurality of first support rods 402 and thereby drives the plurality of cutters 401 to synchronously move away from the rubber roller core. At this time, the pulling effect of the third elastic member on the first support rod 402 can drive the plurality of cutters 401 to synchronously move toward the top support rod 501, and then the plurality of cutters 401 are stored in a position close to the top support rod 501, so as to continue the ring cutting of subsequent rubber rollers.

[0053] See also Figure 6 as well as Figure 7 In one embodiment, the limit baffle 60 is provided with a notch 601 on the plate body below the support ramp 10, and the third driving assembly 70 includes a connecting plate 701, a second rotating shaft 702, a gear 703, a beveled tooth plate 704, a second elastic member 705, a second support rod 706 and a lever 707, wherein the second rotating shaft 702 is rotatably arranged on the bottom wall of the support ramp 10, the gear 703 is fixedly arranged outside the second rotating shaft 702, one end of the connecting plate 701 is fixedly connected to the second rotating shaft 702, and the other end is fixedly connected to the lever 707, the lever 707, the connecting plate 701 and the second rotating shaft 702 are in a Z-shaped structure, and the lever One end of 707 away from the connecting plate 701 passes through the limit baffle 60 from the slot 601, one end of the second support rod 706 is fixedly connected to one group of the slide plates 301, and the other end extends to one side of the gear 703, and the beveled tooth pieces 704 are provided with a plurality of groups, and a plurality of the beveled tooth pieces 704 are hingedly arranged on the side wall of the second support rod 706 and are spaced apart along the length direction of the second support rod 706, and a plurality of the beveled tooth pieces 704 can be unidirectionally meshed with the gear 703, and one side of each group of the beveled tooth pieces 704 is connected to the second support rod 706 through a group of the second elastic members 705, and the second elastic members 705 are used to provide elastic support to the second beveled tooth pieces 704.

[0054] When the motor 305 drives the first rotating shaft 302 to rotate and then drives the two groups of slide plates 301 to move towards each other, one group of slide plates 301 drives the second support rod 706 to move along one side of the gear 703. At this time, a number of bevel gear pieces 704 act on the gear 703 in turn and are pushed by the gear 703 to deflect toward the second support rod 706 in turn. A number of bevel gear pieces 704 cannot mesh with the gear 703, and the limit baffle 60 maintains the limited state for the rubber roller. When the rubber ring of the excess part of the end of a group of rubber rollers is cut, as the motor 305 drives the first rotating shaft 302 to rotate in the opposite direction, the first rotating shaft 302 drives the two groups of slide plates 301 to move away from each other. At this time, one group of slide plates 301 drives the second support rod 706 to move in the opposite direction along one side of the gear 703. The beveled tooth plate 704 meshes with the gear 703 in sequence, thereby pushing the gear 703 to rotate 180°. When the gear 703 rotates 180°, it drives the second rotating shaft 702 to rotate 180°, and then drives the lever 707 to rotate 180° through the connecting plate 701. When the lever 707 rotates 180°, its trajectory is a circular structure, and then through the cooperation with the slot 601, it drives the limit baffle 60 to move downward first compared with the supporting ramp 10. When the upper end of the limit baffle 60 moves down to be flush with the upper surface of the supporting ramp 10, a group of rubber rollers restricted by the limit baffle 60 roll downward along the upper part of the supporting ramp 10 by themselves. When the group of rubber rollers passes over the limit baffle 60, the limit baffle 60 moves upward compared with the supporting ramp 10, and then limits the subsequent rubber rollers again.

[0055] In one embodiment, the first elastic member 503, the second elastic member 705 and the third elastic member may be springs or metal springs, which are not limited here.

[0056] See also Figure 1 , Figure 2 as well as Figure 3 In one embodiment, a plurality of legs are fixedly provided at the bottom of the supporting ramp 10 .

[0057] In the embodiment of the present invention, when it is necessary to cut off the excess rubber at both ends of several rubber rollers, several rubber rollers to be cut can be placed on the upper part of the supporting ramp 10 and several rubber rollers 10 can be arranged in sequence. At this time, the limit baffle 60 acts on one side of the lowest rubber roller, thereby limiting the position of several rubber rollers, and then the first driving component 30 is used to drive the two groups of cutting components 40 to move toward each other. When the two groups of cutting components 40 are in contact with the roller cores at both ends of the lowest rubber roller respectively, the second driving component 50 drives the lowest rubber roller to rotate compared with the two groups of cutting components 40, so as to achieve the effect of the rubber roller being cut off. The two groups of cutting components 40 are used to perform circular cutting on the rubber that exceeds the core of the rubber roller, so as to ensure that the rubber covered on the outside of the roller core is kept flush with the roller core, thereby completing the cutting operation of the current rubber roller; after the current rubber roller is cut, the first driving component 30 drives the two groups of cutting components 40 to move away from each other, and the two groups of cutting components 40 are separated from the core of the lowest rubber roller. At the same time, the third driving component 70 drives the limit baffle 60 to move downward compared to the supporting ramp 10, thereby releasing the limiting state of several rubber rollers. At this time, the lowest rubber roller rolls down along the upper part of the supporting ramp 10 After the rubber roller at the bottom rolls away from the bottom of the supporting ramp 10, the third driving assembly 70 drives the limiting baffle 60 to move upwards compared with the supporting ramp 10, and then acts on the subsequent rubber roller at the lower side to limit the subsequent rubber rollers again. Then, the first driving assembly 30 drives the two groups of cutting assemblies 40 to approach each other again. After the two groups of cutting assemblies 40 act on the two ends of the roller core of the rubber roller at the lower side, the second driving assembly 50 drives the rubber roller at the lower side to rotate compared with the two groups of cutting assemblies 40. The two groups of cutting assemblies 40 target the rubber roller at the lower side. The rubber at both ends of the square rubber roller that exceeds the roller core is cut again, and then the first drive component 30 drives the two groups of cutting components 40 to move away from each other again, and the third drive component 70 drives the limit baffle 60 to move downward again, so that the next lower rubber roller rolls away from the bottom of the supporting ramp 10... Such a reciprocating cycle can realize the continuous automatic cutting operation of several rubber rollers. Compared with the existing technology, it can realize the continuous automatic cutting of the rubber at the ends of several rubber rollers, and there is no need to adjust the position of the rubber roller during the cutting process, which has the advantages of good rubber roller cutting effect and high cutting efficiency.

[0058] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
