Description

Technical Field

[0001] This utility model relates to the field of tire production equipment technology, and in particular to a tire cord material feeding and straight cutting device. Background Technology

[0002] The steel cord fabric of a tire is a composite material made of high-strength steel wire and high-quality rubber. It possesses a variety of excellent properties and is mainly used as the skeleton material in automobile tires and other rubber products, capable of withstanding enormous pressure, impact loads, and strong vibrations. During tire manufacturing, a cord cutting device is used to cut the entire roll of steel cord fabric to a fixed length.

[0003] Currently, existing steel wire straight cutting equipment generally adopts two material feeding and fixed length methods. One is to use a servo motor power roller plus belt conveyor to feed the steel wire curtain to the curtain cutting machine for cutting. The other is to use a magnet to attract the steel wire curtain and use a servo motor to pull the material to feed the steel wire curtain to the curtain cutting machine for cutting.

[0004] The existing technology has at least the following problems: First, due to the extreme weight of the steel cord fabric of the giant tire, slippage is inevitable between the belt and the power roller, resulting in unstable material feeding and length setting, requiring manual assistance, and the pneumatic speed for length setting cannot be high; Second, when the magnet is attracted, there may be cases where it is not attracted, causing abnormal folding of the steel cord fabric during material feeding, generating waste material, affecting normal production, and making it impossible to set the length, requiring manual cleaning; Third, after the cord fabric cutting machine cuts, the rubber on the outside of the steel cord fabric will stick to the cutting blade pressure plate, requiring timely manual separation, otherwise subsequent material feeding will result in material squeezing. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by developing a tire cord fabric feeding and length-fixed cutting device. This invention can eliminate length deviation caused by belt slippage during feeding and can stably clamp the steel cord fabric for material removal, separation, and length feeding, effectively improving the efficiency and effect of steel cord fabric length-fixed cutting and reducing the labor intensity of workers.

[0006] The technical solution of this utility model to solve the technical problem is as follows: a tire cord fabric feeding and fixed-length straight cutting device, including a cord fabric cutting machine, a feeding mechanism is provided on one side of the cord fabric cutting machine, the feeding mechanism includes a first roller conveyor, a positioning clamp and two sets of feeding cylinders, the positioning clamp is slidably set at one end of the top of the first roller conveyor, the two sets of feeding cylinders are respectively set on both sides of the first roller conveyor, one end of the feeding cylinder set is hinged to the frame of the first roller conveyor through a support, and the other end of the feeding cylinder set is hinged to the positioning clamp.

[0007] As an optimization, the positioning clamp includes an installation frame, a first clamping cylinder, a lifting plate, a guide rod, a guide sleeve, and a clamping plate. The first clamping cylinder is mounted on the top plate of the installation frame, and the lifting plate is located inside the installation frame. The piston rod of the first clamping cylinder passes through the installation frame and connects to the lifting plate. The guide rod is mounted on the lifting plate, and the guide sleeve is fitted onto the guide rod. The top of the guide sleeve connects to the installation frame. Two sets of clamping plates are detachably mounted on the bottom of the lifting plate and the inner side of the bottom plate of the installation frame, respectively. By setting up the installation frame, fixing components can be installed; by setting up the first clamping cylinder, the lifting plate can be raised or lowered; by setting up the lifting plate, clamping plates can be installed, which, together with the clamping plates at the bottom of the installation frame, can clamp the steel wire fabric; by setting up the guide rod and guide sleeve, the stability of the lifting plate during raising and lowering can be ensured, guaranteeing the stability of clamping the steel wire fabric; by setting up the clamping plates, the steel wire fabric can be stably clamped.

[0008] As an optimization, the top of the frame of the first roller conveyor is provided with a first slide rail, and the two ends of the mounting frame are provided with first sliders, which are slidably mounted on the first slide rail. By setting the first slide rail and the first sliders, the positioning clamp can slide stably on the frame of the first roller conveyor without shifting.

[0009] As an optimization, the feeding cylinder assembly includes a first feeding cylinder and a second feeding cylinder. The cylinder barrels of the first feeding cylinder are connected to those of the second feeding cylinder. The piston rod of the first feeding cylinder is hinged to the top of the frame of the first roller conveyor via a support, and the piston rod of the second feeding cylinder is hinged to the positioning clamp. By setting the first and second feeding cylinders, the positioning clamp can be driven to perform two-stage displacement strokes, realizing one-stage material retraction and two-stage material feeding actions. Each extension and retraction is a full stroke, which can eliminate slippage deviation caused by friction and ensure the stability and accuracy of the steel cord fabric at a fixed length.

[0010] As an optimization, a traction mechanism and a second roller conveyor are provided on the other side of the fabric cutting machine. The traction mechanism is located above the second roller conveyor, and the height of the feeding end of the second roller conveyor is less than the height of the cutting platform of the fabric cutting machine. By setting up the traction mechanism, the material head can be pulled to allow the steel wire fabric to pass through the fabric cutting machine to a fixed length, which facilitates the cutting of the fabric. By setting up the second roller conveyor, it can receive the steel wire fabric pulled out by the traction mechanism before cutting, and it can also transfer the cut steel wire fabric to the next process, freeing up the workstation to receive the steel wire fabric to be cut again.

[0011] As an optimization, the traction mechanism includes a traction frame, a traction clamp, a drive unit, a top beam, and two sets of gantry frames. Both ends of the top beam are connected to the two sets of gantry frames respectively. A second slide rail is provided on the top beam. The traction frame is slidably mounted on the second slide rail via a second slider. The traction clamp is located at the end of the traction frame facing the fabric cutting machine, and the drive unit is located at the end of the traction frame away from the fabric cutting machine. By setting up the traction frame, the traction clamp and drive unit can be installed on the top beam; by setting up the traction clamp, the material head can be clamped for traction; by setting up the drive unit, the traction frame can be driven to slide along the top beam for pulling or resetting the material; by setting up the top beam, gantry frames, second slider, and second slide rail, the traction frame can slide stably above the second roller conveyor, allowing the pulled steel wire fabric to fall onto the second roller conveyor.

[0012] As an optimization, the traction clamp includes a mounting frame, a second clamping cylinder, a rotating component, a movable clamping plate, and a fixed clamping plate. The mounting frame is mounted on the traction frame. The cylinder of the second clamping cylinder is hinged to one end of the mounting frame, and the piston rod of the second clamping cylinder is hinged to one end of the rotating component. The other end of the rotating component is hinged to the mounting frame, and the middle of the rotating component is connected to the movable clamping plate. The fixed clamping plate is bolted to the other end of the mounting frame, and the movable clamping plate cooperates with the fixed clamping plate. By setting up the mounting frame, the second clamping cylinder, the rotating component, and the fixed clamping plate can be installed and connected to the traction frame. By setting up the second clamping cylinder and the rotating component, they can be linked. When the second clamping cylinder extends, it can push the rotating component forward, thereby causing the movable clamping plate to press down, realizing the clamping action. When the second clamping cylinder retracts, it can pull the rotating component back to rotate backward, thereby causing the movable clamping plate to rise, realizing the releasing action. By setting up the movable clamping plate and the fixed clamping plate, the material head can be clamped or released.

[0013] As an optimization, the drive unit includes a first geared motor and a helical rack. The first geared motor is mounted on the traction frame, and a helical gear is mounted on the output shaft of the first geared motor. The helical rack is mounted on the top beam, and the helical gear meshes with the helical rack. By setting up the first geared motor, power can be provided for the movement of the traction frame. By setting up the helical rack and helical gear, compared with spur gears and racks, it has a higher load-bearing capacity and smoother operation, and can better pull the steel wire cord fabric, so that the first geared motor can drive the traction frame to move along the second slide rail on the top beam.

[0014] Compared with the prior art, the present invention has the following beneficial effects: By setting up a fabric cutting machine, steel wire fabric can be cut; by setting up a feeding mechanism, steel wire fabric can be fed, allowing the material head to pass through the fabric cutting machine. The whole structure is mechanical, stable and reliable; by setting up a first roller conveyor, steel wire fabric can be smoothly transported during feeding; by setting up a positioning clamp, steel wire fabric can be clamped and slidably fed, preventing the steel wire fabric from falling off during feeding; by setting up a feeding cylinder assembly, the positioning clamp can be pushed on the frame of the first roller conveyor to perform retraction and multi-stage feeding actions. The retraction action can disengage the material head from the cutting blade pressure plate of the fabric cutting machine, thereby avoiding adhesion and squeezing during feeding. The multi-stage feeding action can reset the retracted material head, further allowing the material head to pass through the fabric cutting machine. Moreover, the feeding cylinder assembly, together with the positioning clamp and the first roller conveyor, is a purely mechanical structure. Each movement is a fixed distance, which can eliminate slippage deviation caused by friction and ensure the stability and accuracy of the steel wire fabric at a fixed length. This invention can eliminate the deviation in length caused by belt slippage during material feeding, and can stably clamp the steel wire cord fabric for material unloading, separation and length feeding, effectively improving the efficiency and effect of steel wire cord fabric length cutting and reducing the labor intensity of workers.

[0027] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0028] Figures 1 to 11 As one embodiment of this utility model, such as Figures 1 to 11 As shown, the tire cord fabric feeding and fixed-length straight cutting device includes a cord fabric cutting machine 2. A feeding mechanism 1 is provided on one side of the cord fabric cutting machine 2. The feeding mechanism 1 includes a first roller conveyor 5, a positioning clamp 6, and two sets of feeding cylinder groups 7. The positioning clamp 6 is slidably disposed at one end of the top of the first roller conveyor 5. The first roller conveyor 5 is a non-powered roller conveyor. The two sets of feeding cylinder groups 7 are respectively disposed on both sides of the top of the first roller conveyor 5. One end of the feeding cylinder group 7 is hinged to the frame of the first roller conveyor 5 through a support, and the other end of the feeding cylinder group 7 is hinged to the positioning clamp 6.

[0029] By setting up the fabric cutting machine 2, the steel wire fabric 33 can be cut; by setting up the feeding mechanism 1, the steel wire fabric 33 can be fed, allowing the material head to pass through the fabric cutting machine 2. The whole structure is mechanical, stable and reliable; by setting up the first roller conveyor 5, the steel wire fabric 33 can be smoothly transported during feeding; by setting up the positioning clamp 6, the steel wire fabric 33 can be clamped and slidably fed, preventing the steel wire fabric 33 from falling off during feeding; by setting up the feeding cylinder group 7, the positioning clamp 6 can be pushed. The material unloading and multi-stage feeding actions are performed on the frame of the first roller conveyor 5. The unloading action can disengage the material head from the cutting plate of the fabric cutting machine 2, thereby avoiding adhesion and squeezing during feeding. The multi-stage feeding action can reset the unloaded material head and further allow the material head to pass through the fabric cutting machine 2. The feeding cylinder group 7, together with the positioning clamp 6 and the first roller conveyor 5, is a purely mechanical structure. Each movement is a fixed distance, which can eliminate slippage deviation caused by friction and ensure the stability and accuracy of the fixed length of the steel wire fabric 33.

[0030] like Figure 1 and Figure 2 As shown, the positioning clamp 6 includes an installation frame 8, a first clamping cylinder 9, a lifting plate 10, a guide rod 11, a guide sleeve 12, and a clamping plate 13. The first clamping cylinder 9 is mounted on the top plate of the installation frame 8, and the lifting plate 10 is mounted inside the installation frame 8. The piston rod of the first clamping cylinder 9 passes through the top plate of the installation frame 8 and is connected to the lifting plate 10. The guide rod 11 is vertically mounted on the lifting plate 10, and the guide sleeve 12 is mounted on the guide rod 11. The top of the guide sleeve 12 is connected to the top plate of the installation frame 8. The two sets of clamping plates 13 are detachably mounted on the bottom of the lifting plate 10 and the inner side of the bottom plate of the installation frame 8 by bolts. The clamping plates 13 are provided with an anti-stick coating. By setting the mounting frame 8, fasteners can be installed; by setting the first clamping cylinder 9, the lifting plate 10 can be raised or lowered; by setting the lifting plate 10, clamping plates 13 can be installed, which, together with the clamping plates 13 at the bottom of the mounting frame 8, can clamp the steel wire curtain 33; by setting the guide rod 11 and the guide sleeve 12, the stability of the lifting plate 10 during lifting can be ensured, and the stability of clamping the steel wire curtain 33 can be ensured; by setting the clamping plates 13, the steel wire curtain 33 can be stably clamped.

[0031] like Figure 1 and Figure 2 As shown, the top of the frame on both sides of the first roller conveyor 5 is provided with a first slide rail 14, and the two ends of the mounting frame 8 are provided with a first slider 15 through a connecting frame. The first slider 15 is slidably mounted on the first slide rail 14. By setting the first slide rail 14 and the first slider 15, the positioning clamp 6 can slide stably on the frame of the first roller conveyor 5 without deviating.

[0032] like Figures 1 to 4 and Figures 9 to 11As shown, the feeding cylinder assembly 7 includes a first feeding cylinder 16 and a second feeding cylinder 17. The cylinder end of the first feeding cylinder 16 is connected to the cylinder end of the second feeding cylinder 17 via a connecting plate. The piston rod of the first feeding cylinder 16 is hinged to the top of the frame of the first roller conveyor 5 via a support. The piston rod of the second feeding cylinder 17 is hinged to the connecting frames at both ends of the positioning clamp 6. By setting the first feeding cylinder 16 and the second feeding cylinder 17, the positioning clamp 6 can be driven to perform two-stage displacement strokes, realizing one-stage material retraction and two-stage material feeding actions. Each extension and retraction is a full stroke, which can eliminate slippage deviation caused by friction and ensure the stability and accuracy of the fixed length of the steel wire cord fabric 33.

[0033] like Figure 1 and Figures 3 to 11 As shown, a traction mechanism 3 and a second roller conveyor 4 are provided on the other side of the fabric cutting machine 2. The second roller conveyor 4 is a non-powered roller conveyor. The traction mechanism 3 is located above the second roller conveyor 4, and the height of the feeding end of the second roller conveyor 4 is less than the height of the cutting platform of the fabric cutting machine 2. By setting up the traction mechanism 3, the material head can be pulled to pull the material, so that the steel wire fabric 33 passes through the fabric cutting machine 2 to a fixed length, which facilitates the cutting of the fabric cutting machine 2. By setting up the second roller conveyor 4, it can receive the steel wire fabric 33 pulled out by the traction mechanism 3 before cutting, and it can transfer the cut steel wire fabric 33 to the next process, freeing up the workstation to receive the cut steel wire fabric 33 again.

[0034] like Figure 1 and Figures 3 to 7 As shown, the traction mechanism 3 includes a traction frame 18, a traction clamp 19, a drive device 20, a top beam 21, and two sets of gantry frames 22. The top beam 21 has three sets, and both ends of the top beam 21 are connected to the two sets of gantry frames 22 respectively. The span of the two sets of gantry frames 22 can be set according to the actual situation. The top beam 21 on both sides is provided with a second slide rail 23. The traction frame 18 is slidably mounted on the second slide rail 23 through the second slider 24. The traction clamp 19 is located at the end of the traction frame 18 facing the curtain cutting machine 2, and the drive device 20 is located at the end of the traction frame 18 away from the curtain cutting machine 2. By setting up the traction frame 18, the traction clamp 19 and the drive device 20 can be installed on the top beam 21; by setting up the traction clamp 19, the material head can be clamped for traction; by setting up the drive device 20, the traction frame 18 can be driven to slide along the top beam 21 for pulling or resetting; by setting up the top beam 21, the gantry frame 22, the second slider 24 and the second slide rail 23, the traction frame 18 can slide stably above the second roller conveyor 4, so that the pulled steel wire cord 33 falls onto the second roller conveyor 4.

[0035] like Figure 7As shown, the traction clamp 19 includes a mounting frame 25, a second clamping cylinder 26, a rotating component 27, a movable clamping plate 28, and a fixed clamping plate 29. The mounting frame 25 is mounted on the traction frame 18. The cylinder of the second clamping cylinder 26 is hinged to one end of the mounting frame 25. The piston rod of the second clamping cylinder 26 is hinged to one end of the rotating component 27. The other end of the rotating component 27 is hinged to the mounting frame 25. The middle part of the rotating component 27 is connected to the movable clamping plate 28. The fixed clamping plate 29 is mounted on the other end of the mounting frame 25 by bolts. The movable clamping plate 28 and the fixed clamping plate 29 cooperate with each other. The mounting bracket 25 allows for the installation of a second clamping cylinder 26, a rotating component 27, and a fixed clamping plate 29, which can be connected to the traction frame 18. The second clamping cylinder 26 and the rotating component 27 can be linked together. When the second clamping cylinder 26 extends, it pushes the rotating component 27 forward, causing the movable clamping plate 28 to press down, thus achieving a clamping action. When the second clamping cylinder 26 retracts, it pulls the rotating component 27 backward, causing the movable clamping plate 28 to rise, thus achieving a releasing action. The movable clamping plate 28 and the fixed clamping plate 29 allow for the clamping or releasing of the material head.

[0036] like Figure 5 and Figure 6 As shown, the drive device 20 includes a first geared motor 30 and a helical rack 31. The first geared motor 30 is mounted on the traction frame 18 and includes a servo motor and a reducer. A helical gear 32 is provided on the output shaft of the first geared motor 30, and the helical rack 31 is mounted on a set of top beams 21 in the middle. The helical gear 32 meshes with the helical rack 31. By setting the first geared motor 30, power can be provided for the movement of the traction frame 18. By setting the helical rack 31 and helical gear 32, compared with spur gears and racks, it has a higher load-bearing capacity and smoother operation, and can better pull the steel wire curtain 33, so that the first geared motor 30 can drive the traction frame 18 to move along the second slide rail 23 on the top beam 21.

[0037] During use, the operator passes the end of the steel wire cord fabric roll through the two sets of clamping plates 13 of the positioning clamp 6 and the cutting blade of the fabric cutting machine 2 in sequence, and starts the equipment to perform step one, such as... Figure 8 As shown, the first material clamping cylinder 9 presses down the lifting plate 10, causing the two sets of clamping plates 13 to clamp the steel wire curtain 33. The cutting blade of the curtain cutting machine 2 cuts off the initial waste material head. At this time, the material head is flush with the edge of the cutting blade pressure plate of the curtain cutting machine 2. The piston rod of the first feeding cylinder 16 is in the retracted state, and the piston rod of the second feeding cylinder 17 is in the extended state. Step two, as Figure 9As shown, the second feeding cylinder 17 retracts its piston rod to perform a material feeding action, which drives the positioning clamp 6 to move backward on the first slide rail 14 away from the curtain fabric cutting machine 2, causing the material head to move backward, so that the material head is misaligned with the edge of the cutting plate, thereby avoiding adhesion; then the first feeding cylinder 16 and the second feeding cylinder 17 both extend their piston rods to perform a two-stage feeding action, which drives the positioning clamp 6 to move forward on the first slide rail 14 towards the curtain fabric cutting machine 2, so that the material head protrudes out of the cutting plate of the curtain fabric cutting machine 2; Step 3, as Figure 10 As shown, the first reduction motor 30 drives the traction frame 18 to move along the second slide rail 23 on the top beam 21 toward the curtain cutting machine 2, so that the traction clamp 19 connects with the material head of the steel wire curtain 33, and the material head enters between the movable clamp 28 and the fixed clamp 29. Step four, as Figure 11 As shown, the piston rod of the second clamping cylinder 26 extends, pushing the rotating part 27 to rotate forward, thereby driving the movable clamping plate 28 to press down, cooperating with the fixed clamping plate 29 to clamp the head of the wire cord fabric 46. The piston rod of the first clamping cylinder 9 retracts, raising the lifting plate 10, causing the two sets of clamping plates 13 to release the wire cord fabric 33. The first feeding cylinder 16 retracts the piston rod, driving the positioning clamping 6 to retract and reset. Step 5: While the positioning clamp 6 is reset, the first reduction motor 30 drives the traction frame 18 to move along the second slide rail 23 on the top beam 21 in a direction away from the curtain cutting machine 2, so that the traction clamp 19 pulls the steel wire curtain 33 along the second roller conveyor 4 to achieve a fixed length of the curtain. After the first reduction motor 30 moves to the fixed length position, it stops moving, and at this time the positioning clamp 6 has been reset. Then, the first clamp cylinder 9 presses down the lifting plate 10, so that the two sets of clamping plates 13 clamp the steel wire curtain 33. The cutter of the curtain cutting machine 2 presses down, and the cutter pressure plate cuts the steel wire curtain 33. The feeding cylinder group 7 starts to repeat the working process of steps one to five. Step six: The first reduction motor 30 drives the traction frame 18 to move along the second slide rail 23 on the top beam 21 towards the material discharge end of the second roller conveyor 4. The second roller conveyor 4 is equipped with a transfer device at the material discharge end, which can be a power roller or a conveyor belt. This transfer device transfers the cut steel wire cord fabric 33 to the next process. After the traction clamp 19 brings the cut steel wire cord fabric 33 onto the transfer device, it releases the steel wire cord fabric 33 and begins to repeat steps three through six, providing continuous traction. This invention eliminates the length deviation caused by belt slippage during material delivery and stably clamps the steel wire cord fabric 33 for material removal, separation, and length delivery, effectively improving the efficiency and effect of length-cutting the steel wire cord fabric 33 and reducing the labor intensity of workers.
