Description

Technical Field

[0001] This invention relates to machinery for cutting rubber, and more particularly to an automatic rubber slitting machine for dividing rubber sheets into strips of specified widths and lengths. Background Technology

[0002] In the production of rubber tracks, rubber, steel wire rope, and metal teeth (core metal) are first compounded to form a pre-formed track blank, which is then vulcanized. "Teeth stamping" is a step in the pre-forming process of rubber tracks, requiring strips of mixed rubber compound. Therefore, the mixed rubber sheet needs to be cut into strips of specified widths and lengths. In existing technology, a slitting and cutting device is typically used to cut the rubber sheet into specific widths, and then a cutting device is used to cut it into the required lengths to obtain the desired strips. However, the cut strips need to be manually transported to a designated loading cart, and once the cart is full, they are transferred to the teeth stamping station. This loading method is extremely labor-intensive for workers, requires multiple workers for each machine, and results in high labor costs. Furthermore, different cutting rollers need to be changed for different width requirements, which is cumbersome and affects production efficiency. If a separate machine is needed for different width cutting requirements, it would not only result in a large investment in equipment but also occupy a significant amount of factory space.

[0003] Patent document CN 219006288 U discloses a novel rubber sheet slitting and stacking device, which stacks the slitting rubber sheets into a storage device, thereby reducing the workload of workers. However, in this patent document, the rubber strips do not need to be cut, and it cannot achieve automatic placement of the cut rubber strips. In the prior art, there is no mechanical equipment that can realize the slitting and cutting of rubber sheets and the automatic placement of rubber strips. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this application provides an automatic rubber slitting machine for dividing rubber sheets into strips of specified widths and lengths. This automatic rubber slitting machine can automatically place the slit rubber strips onto a material handling carriage, eliminating the need for manual placement, significantly reducing worker workload and labor costs, and improving enterprise efficiency. Furthermore, this automatic rubber slitting machine can produce rubber strips of different widths by changing the cutter assembly; it is easy to operate and does not affect production efficiency.

[0005] The technical solution of this application is as follows:

[0006] An automatic rubber slitting machine for dividing rubber sheets into strips of specified width and length includes, in sequence, a first belt conveyor, a slitting and cutting device, a cutting device, a second belt conveyor, and a material placement device. During operation, the first belt conveyor transports the rubber sheet forward. As the rubber sheet passes the slitting and cutting device, it is cut to the specified width, then cut to the specified length by the cutting device, and finally transported forward by the second belt conveyor into the material placement device. The material placement device includes a guide rail, a parking platform, a drive assembly, and a material placement trolley. The material placement trolley is parked on the parking platform and includes a cargo box and a bottom portion of the cargo box. The parking platform is driven by a drive assembly to move along a guide rail. The length and installation position of the guide rail allow the parking platform to be retracted into the frame of the second belt conveyor and to be moved outside the frame of the second belt conveyor. The outer end of the hopper is provided with a material support crossbar. During operation, the parking platform is first retracted into the frame of the second belt conveyor. After the rubber strip delivered from the end of the second belt conveyor is hung on the material support crossbar, the drive assembly drives the parking platform to move outward, so that the rubber strip gradually falls into the hopper. When the rubber strip has completely fallen into the hopper, the two ends of the rubber strip are located at the two ends of the hopper.

[0007] Compared with the prior art, the material handling device in this invention consists of a guide rail, a parking platform, a drive assembly, and a material handling trolley. The material handling trolley can be stored in the frame of the second belt conveyor. After the cut rubber strips are sent out from the second belt conveyor and hung on the material support crossbar at the outer end of the material handling trolley, the material handling trolley moves outward, causing the rubber strips to gradually fall into the hopper. When the rubber strips have completely fallen into the hopper, the two ends of the rubber strips are located at the two ends of the hopper, realizing automatic material handling. The whole process does not require manual intervention. After the hopper of the material handling trolley is filled with rubber strips, workers can be arranged to pull the material handling trolley away and replace it with an empty material handling trolley. The labor intensity is greatly reduced, and labor costs can be significantly reduced, thereby improving enterprise efficiency.

[0008] As an optimization, in the aforementioned automatic rubber slitting machine for dividing rubber sheets into strips of specified width and length, the first belt conveyor is equipped with a conveying length measuring device. During operation, when the conveying length measuring device detects that the continuous conveying length of the first belt conveyor has reached the design value, the first belt conveyor stops, the cutting device cuts the rubber sheet, and then the first belt conveyor restarts. Thus, the length of the rubber strip can be precisely controlled using the conveying length measuring device, and it is easy to implement. Furthermore, the conveying length measuring device includes a support crossbar, a connecting rod, and a meter counter; the support crossbar spans across the conveyor belt of the first belt conveyor, the connecting rod is fixedly connected to the support crossbar, and the meter counter is hinged to the connecting rod; the meter counter can be mounted on the support crossbar by flipping. After the film is released from the winding device, it needs to be fed into the slitting machine. Using the aforementioned conveying length measuring device, the meter counter can be mounted on the support crossbar to facilitate the feeding of the film into the slitting machine. After the film is successfully fed in, the meter counter is flipped so that its measuring wheel is in contact with the film on the conveyor belt to measure the conveying length of the film.

[0009] As an optimization, in the aforementioned automatic rubber slitting machine for dividing rubber sheets into strips of specified widths and lengths, the slitting and cutting device includes a drive assembly and a cutting tool assembly. The drive assembly includes a fixed bracket and a first drive motor mounted on the fixed bracket. The cutting tool assembly includes a movable bracket with a pair of matching cutting rollers forming a cutting roller group, the two cutting rollers being connected via a gear transmission mechanism. The movable bracket is interchangeably connected to the fixed bracket, with one cutting roller being connected to the first drive motor. On the movable bracket, a support plate is provided on each side of the middle portion of the cutting roller group. The two support plates are respectively connected to a first belt conveyor and a cutting device. Therefore, by changing the cutting tool assembly, slitting processing of different widths can be achieved, and the machine is simple and convenient to operate. Furthermore, the fixed bracket is equipped with a front limiting block and a rear limiting block. The movable bracket is placed between the front and rear limiting blocks and abuts against them to form a limiting position. The fixed bracket is equipped with a rotatable transmission sleeve. The shaft of the first drive motor is connected to one end of the transmission sleeve, and the other end of the transmission sleeve is connected to one of the cutting rollers via a key transmission structure. This structural design cleverly utilizes the characteristic that the tool assembly is only subjected to force in the longitudinal direction and not in the lateral direction. Reliable limiting is achieved using the front and rear limiting blocks. When the tool assembly needs to be replaced, simply pull the movable bracket out laterally and then push in the required tool assembly laterally, further improving operational convenience.

[0010] As an optimization, in the aforementioned automatic rubber slitting machine for dividing rubber sheets into strips of specified width and length, the cutting roller includes a roller shaft and roller blades sleeved on the roller shaft. One roller blade on one cutting roller slides on the roller shaft and is circumferentially limited by a key transmission structure. One end of this roller blade abuts against a pre-compression spring sleeved on the roller shaft. The roller blade on the other cutting roller is fixedly connected to the roller shaft. The blades of the two cutting rollers abut against each other and are pressed together by the spring force of the pre-compression spring. After long-term use, the blades on the roller blades will wear, resulting in a small gap between the blades on the two roller blades, affecting the slitting quality, producing burrs, requiring manual trimming, and in severe cases, even causing the slitting strips to not meet the required width, resulting in defective products. The cutting roller with the above-mentioned structural design allows one roller blade to slide on the roller shaft, and the pre-compression spring presses the blades on both roller blades together, ensuring a tight fit even after blade wear, thus guaranteeing slitting quality. Furthermore, the outer end of the preload spring abuts against a shoulder on the roller shaft, and the inner end abuts against the roller cutter. This prevents wear of the preload spring due to friction and is easy to implement. Furthermore, the end of the roller cutter that slides with the roller shaft has a clearance hole, in which the preload spring is located. Thus, the preload spring is hidden in the clearance hole at the end of the roller cutter, resulting in a compact structure and reducing the lateral dimension of the cutter assembly.

[0011] As an optimization, in the aforementioned automatic rubber slitting machine for dividing rubber sheets into strips of specified width and length, the second belt conveyor operates at a faster speed than the first belt conveyor. Therefore, before cutting, the second belt conveyor pulls the rubber sheet forward, keeping it flat and ensuring cutting quality.

[0012] As an optimization, in the aforementioned automatic rubber slitting machine for dividing film into strips of specified width and length, a slider is provided on the guide rail, and the parking platform is fixedly connected to the slider. The slider on the guide rail forms a linear module, which can be directly purchased from the market, is easy to implement, and has high reliability.

[0013] As an optimization, in the aforementioned automatic rubber slitting machine for dividing film into strips of specified width and length, the drive assembly includes a lead screw and a second drive motor, the second drive motor being driven by the lead screw, and the lead screw being driven by the parking platform. Using an electric lead screw mechanism to drive the parking platform is easy to implement and highly reliable.

[0014] As an optimization, in the aforementioned automatic rubber slitting machine for dividing rubber sheets into strips of specified width and length, the outer end of the guide rail is provided with a ramp. When the parking platform moves to the outer end of the guide rail, the ramp connects with the parking platform. This makes changing the loading cart more convenient; after the loading cart is full of rubber, it can be pulled out along the ramp and then pushed into an empty loading cart along the ramp.

[0015] As an optimization, in the aforementioned automatic rubber slitting machine for dividing film into strips of specified width and length, a limiting structure is provided on the parking platform, ensuring that the material handling trolley can only move along a straight path on the parking platform. By setting the limiting structure, when changing the material handling trolley, the trolley can travel in a straight line to reach the designated position, facilitating operation.

[0016] As an optimization, in the aforementioned automatic rubber slitting machine for dividing rubber sheets into strips of specified width and length, a first photoelectric sensor is installed near its end on the second belt conveyor; a second photoelectric sensor is installed below the end of the second belt conveyor. During operation, when the first photoelectric sensor detects a rubber strip, the control system starts timing. After the timing reaches the set time, the drive assembly drives the parking platform to move outward. After the second photoelectric sensor detects that the parking platform has moved to the outer end of the guide rail, the drive assembly switches its running direction and drives the parking platform to move inward to reset. After the second photoelectric sensor detects that the parking platform has reset, the drive assembly stops operating. This sensor solution meets the operational requirements, is easy to implement, has low cost, and high reliability. Attached Figure Description

Detailed Implementation

[0022] The technical solution of this application will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the technical solution of this application. In the following embodiments, content not described in detail or not shown in detail in the accompanying drawings is common knowledge in the art.

[0023] Example (see) Figures 1-6 ):

[0024] An automatic rubber slitting machine for dividing rubber sheets into strips of specified width and length includes a first belt conveyor 1, a slitting and cutting device 2, a cutting device 3, a second belt conveyor 4, and a material placement device 5, arranged in sequence. During operation, the first belt conveyor 1 transports the rubber sheet forward. The sheet is cut to the specified width by the slitting and cutting device 2, then cut to the specified length by the cutting device 3, and finally transported forward by the second belt conveyor 4 into the material placement device 5. The compounded rubber sheet, after passing through the automatic rubber slitting machine, is divided into strips of specified width and length and placed in the material placement device 5 for later use.

[0025] In this embodiment, the material handling device 5 includes a guide rail 501, a parking platform 502, a drive assembly 503, and a material handling trolley 504; the material handling trolley 504 is parked on the parking platform 502, and includes a bucket 5041 and wheels 5042 located at the bottom of the bucket 5041; the parking platform 502 can be driven by the drive assembly 503 to move along the guide rail 501; the length and installation position of the guide rail 501 allow the parking platform 502 to be housed within the frame of the second belt conveyor 4 and to be moved to the first... The second belt conveyor 4 is located outside its frame. The outer end of the hopper 5041 is equipped with a material-supporting crossbar 5043. During operation, the parking platform 502 is first retracted into the frame of the second belt conveyor 4. After the rubber strip delivered from the end of the second belt conveyor 4 is hooked onto the material-supporting crossbar 5043, the drive assembly 503 drives the parking platform 502 to move outward, causing the rubber strip to gradually fall into the hopper 5041. When the rubber strip is completely inside the hopper 5041, both ends of the rubber strip are located at opposite ends of the hopper 5041. After the hopper 5041 is filled with rubber strips, the worker pulls out the material-unloading cart 504 and replaces it with a spare hopper 5041.

[0026] In this embodiment, the first belt conveyor 1 is equipped with a conveying length measuring device 6. When the conveying length measuring device 6 detects that the continuous conveying length of the first belt conveyor 1 has reached the design value (the design value is the length of the rubber strip after cutting), the first belt conveyor 1 stops, the cutting device 3 cuts the rubber sheet, and then the first belt conveyor 1 restarts.

[0027] In this embodiment, the conveying length measuring device 6 includes a support crossbar 601, a connecting rod 602, and a meter counter 603. The support crossbar 601 spans across the conveyor belt of the first belt conveyor 1. The connecting rod 602 is fixedly connected to the support crossbar 601, and the meter counter 603 is hinged to the connecting rod 602. The meter counter 603 can be mounted on the support crossbar 601 by flipping. At the start of operation, the meter counter 603 is first mounted on the support crossbar 601 (i.e., attached). Figure 1 As shown in the diagram, the compounded rubber sheet is released from the winding machine and conveyed forward by the first belt conveyor 1, gradually entering the slitting machine. After passing through the meter counter 603 at the front end of the sheet, the meter counter 603 is flipped so that the measuring wheel of the meter counter 603 presses onto the sheet (i.e., ...). Figures 4-6 (as shown in the image).

[0028] In this embodiment, the slitting and cutting device 2 includes a drive assembly and a cutting tool assembly. The drive assembly includes a fixed bracket 201 and a first drive motor 202 mounted on the fixed bracket 201. The cutting tool assembly includes a movable bracket 203, on which a pair of matching cutting rollers 204 are provided to form a cutting roller group. The two cutting rollers 204 are connected by a gear transmission mechanism 205. The movable bracket 203 is interchangeably connected to the fixed bracket 201, and one cutting roller 204 is connected to the first drive motor 202. On the movable bracket 203, on both sides of the middle of the cutting roller group, a support plate 207 is provided (the support plate 207 allows the film to pass straight between the two cutting rollers 204, preventing burrs). The two support plates 207 are respectively connected to the first belt conveyor 1 and the cutting device 3. To meet the production requirements of different cutting widths, the slitting machine is equipped with multiple specifications (different blade spacing distances) of cutting tool assemblies. During production, the appropriate cutting tool assembly is used as needed.

[0029] In this embodiment, the fixed bracket 201 is provided with a front limiting block 2011 and a rear limiting block 2012. The movable bracket 203 is placed between the front limiting block 2011 and the rear limiting block 2012 and abuts against them to form a limiting position. The fixed bracket 201 is provided with a rotatable transmission sleeve 206. The shaft of the first drive motor 202 is connected to one end of the transmission sleeve 206, and the other end of the transmission sleeve 206 is connected to one of the cutting rollers 204 via a key transmission structure. In use, the tool assembly can be replaced simply by pulling it out laterally and then pushing in the tool assembly to be replaced.

[0030] In this embodiment, the bottom of the movable support 203 is equipped with casters with brakes for easy movement and low implementation cost. When movement is needed, the brakes are unlocked; after movement is complete, the brakes are locked to improve stability.

[0031] In this embodiment, the cutting roller 204 includes a roller shaft 2041 and roller blades 2042 sleeved on the roller shaft 2041. One roller blade 2042 on one cutting roller 204 is slidably engaged with the roller shaft 2041 and circumferentially limited by a key transmission structure. One end of this roller blade 2042 abuts against a pre-compression spring 2043 sleeved on the roller shaft 2041. The other cutting roller 2042 is fixedly connected to the roller shaft 2041. The blades of the two cutting rollers 204 abut against each other and are pressed together by the spring force of the pre-compression spring 2043. In conventional designs, the roller shaft 2041 and roller blades 2042 are fixedly connected and cannot move relative to each other. After the blades on the roller blades 2042 wear down, a small gap will form between the blades on the two roller blades 2042, affecting the cutting quality. The cutting roller 204 adopts the above-mentioned structural design, in which one of the roller blades 2042 can slide on the roller shaft 2041. The blades on the two roller blades 2042 are pressed together by the pre-tight compression spring 2043, so that they can still fit tightly after the blades wear out, ensuring the cutting quality.

[0032] In this embodiment, the outer end of the pre-compression spring 2043 abuts against the shoulder on the roller shaft 2041, and the inner end abuts against the roller cutter 2042. During operation, the pre-compression spring 2043 is stationary relative to the roller shaft 2041 and the roller cutter 2042, resulting in no friction and minimal wear.

[0033] In this embodiment, the end of the roller cutter 2042 that slides with the roller shaft 2041 is provided with a clearance hole, and the preload compression spring 2043 is located in the clearance hole. Thus, the preload compression spring 2043 is hidden in the clearance hole at the end of the roller cutter 2042, resulting in a compact structure that helps reduce the lateral dimensions of the cutter assembly and minimizes the space occupied in the workshop.

[0034] In this embodiment, the second belt conveyor 4 operates at a faster speed than the first belt conveyor 1. This faster speed ensures the film remains flat before cutting, resulting in high cutting precision.

[0035] In this embodiment, a slider 505 is provided on the guide rail 501, and the parking platform 502 is fixedly connected to the slider 505. The slider 505 and the guide rail 501 constitute a linear module, which can be directly purchased from the market and is easy to implement.

[0036] In this embodiment, the drive assembly 503 includes a lead screw 5031 and a second drive motor 5032. The second drive motor 5032 is driven by the lead screw 5031, and the lead screw 5031 is driven by the parking platform 502. During operation, the second drive motor 5032 drives the lead screw 5031 to rotate, thereby driving the parking platform 502 to move along the guide rail 501. This method is easy to implement and has high reliability.

[0037] In this embodiment, the outer end of the guide rail 501 is provided with a ramp 506. When the parking platform 502 moves to the outer end of the guide rail 501, the ramp 506 connects with the parking platform 502. The ramp 506 facilitates the replacement of the material handling trolley 504.

[0038] In this embodiment, the parking platform 502 is provided with a limiting structure 5021, which ensures that the material handling trolley 504 can only move along the straight lane 5022 on the parking platform 502. The limiting structure 5021 can guide the material handling trolley 504 to move along the straight lane 5022, so that the worker does not need to control the direction of the material handling trolley 504, making the operation simple and convenient.

[0039] In this embodiment, a first photoelectric sensor 7 is provided near the end of the second belt conveyor 4; a second photoelectric sensor 8 is provided below the end of the second belt conveyor 4. During operation, when the first photoelectric sensor 7 detects the rubber strip, the control system starts timing. After the timing reaches the set time, the drive assembly 503 drives the parking platform 502 to move outward. After the second photoelectric sensor 8 detects that the parking platform 502 has moved to the outer end of the guide rail 501, the drive assembly 503 switches its running direction and drives the parking platform 502 to move inward to reset. After the second photoelectric sensor 8 detects that the parking platform 502 has reset, the drive assembly 503 stops running. The timing duration is determined based on the running speed of the second belt conveyor, ensuring that the rubber strip is hung on the material support crossbar 5043 as required, so that the outer end of the rubber strip can fall to the outer end of the hopper 5041 (see...). Figure 6 The sensing scheme is relatively simple, easy to implement, low in cost, and highly reliable.

[0040] The foregoing general description of the invention and its specific embodiments should not be construed as a limitation on the technical solution of the invention. Those skilled in the art, based on the disclosure of this application, can add, reduce, or combine the disclosed technical features in the foregoing general description and / or specific embodiments (including examples) without departing from the constituent elements of the invention, to form other technical solutions within the scope of protection of this application.
