Description

Technical Field

[0001] The present invention belongs to the technical field of chain processing and cutting, and specifically relates to a chain processing and cutting device. Background Art

[0002] The roller chain is a widely used type of chain, which mainly consists of chain plates, pins, and rollers. During the production and processing of roller chains, after the roller chains are detected and qualified, they need to be cut into specific lengths according to requirements. Usually, automated chain cutting equipment is used for cutting processing, which can not only improve the efficiency of chain cutting processing, but also reduce manual intervention and ensure cutting accuracy.

[0003] The patent with publication number CN209902601U discloses a cutting device for a chain detection and packaging system, including a frame. A machine table is installed on the top of the frame. A chain passing groove for conveying the chain is provided on the machine table. A cutting mechanism for cutting the chain is provided above the chain passing groove. A sprocket for engaging the chain is rotatably installed on the machine table, and the sprocket is driven by a motor. The machine table is also provided with a positioning mechanism for positioning the chain. In this solution, the sprocket is driven to drive the chain to slide along the chain groove, so that the cut chain reaches a preset length, and then the chain is cut by the cutting mechanism. During this process, the corresponding pins on the chain are pressed out, so as to complete the fixed-length cutting of the chain. The automation degree is high, and the cutting process is fast and accurate.

[0004] In the above solution, after the corresponding pins on the chain are pressed out, the pins and the corresponding chain plates will be separated from the chain and fall into the chain passing groove. Therefore, the staff needs to clean up the pins and chain plates before cutting the next group of chains. Cleaning the pins and chain plates will take a lot of time, which not only reduces the automation rate of the device, but also reduces the cutting efficiency of the chain. Therefore, the present invention provides a chain processing and cutting device. Summary of the Invention

The material blocking mechanism includes a sliding seat, which is movably installed on a set of support plates, a cylinder fixedly connected to one end of the sliding seat, the cylinder is fixedly installed on a set of support plates, two sets of pin heads are fixedly installed on the other end of the sliding seat, opening grooves are symmetrically opened on both sides of the chain passing groove, two sets of material blocking blocks are respectively inserted into the two opening grooves, two avoidance holes for the pin heads to pass through are opened on the material blocking blocks, an electric push rod for driving the material blocking blocks, the electric push rod is fixedly installed on the support plate, a vibration motor is fixedly installed on a set of support plates, and a material discharging box is arranged at the lower end of the chain passing groove; During the cutting process of the chain in this solution, the pins and chain plates generated by cutting will be automatically recovered into the material discharging box, thereby avoiding the influence of the pins and chain plates on the cutting of the next chain, not only improving the automation rate of the device, but also improving the cutting efficiency of the chain.

[0007] Preferably, two guiding grooves are opened on a set of support plates, and two sliding rails are arranged on the lower end surface of the sliding seat, and the sliding rails are slidably connected to the guiding grooves; The cooperation of the sliding rails and the guiding grooves plays a guiding role in the movement of the sliding seat.

[0008] Preferably, the material blocking block includes a block body, the block body is movably inserted into the opening groove, a movable plate is arranged on one side of the block body, the output end of the electric push rod is connected to the movable plate, four guide posts movably inserted on the movable plate, springs sleeved on the guide posts, one end of a magnet column is fixedly connected to the movable plate, four installation grooves are opened on the block body, one ends of the four guide posts are respectively fixedly installed in the four installation grooves, one ends of the four springs are fixedly connected to the movable plate, and the other ends of the four springs are respectively fixedly connected to the bottoms of the four installation grooves.

The two sets of chain plates slide along the corresponding flow channels into the cavities on both sides of the material discharging box, separating the chain plates and the pins, realizing the classification of the chain plates and the pins, and facilitating the subsequent processing of the chain plates and the pins by the staff.

[0009] Preferably, the material blocking mechanism further includes a linkage mechanism, which includes a gear, which is rotatably mounted in the frame, two sets of racks are meshed with the gears, one end of the two sets of racks are respectively connected to two sets of movable plates, a rectangular cavity is provided in the frame, the gears are rotatably mounted in the rectangular cavity, guide holes are provided on both sides of the machine base, the guide holes are connected to the rectangular cavity, and the racks are movably plugged into the guide holes; When a group of electric push rods drives the corresponding stop blocks to move, the movable plate on the stop blocks drives the corresponding racks to slide along the guide holes, and the moving racks drive another group of racks to move through gears, and the other group of racks drives another group of stop blocks to move synchronously, thereby achieving the above-mentioned distance from or blocking of the opening grooves.

[0011] 2. When the two sets of pin pressing heads push the pin shaft out of the two sets of avoidance holes on the other set of material stopper blocks, the pin shaft will fall into the flow channel inside the second material guide strip, so that the pin shaft will roll along the flow channel into the cavity in the middle area of the material discharge box. When the electric push rod drives the material stopper block away from the open slot, the magnet column will attract the chain plate, so that the chain plate will be separated from the chain slot along with the material stopper block. At the same time, the slide groove at the lower end of the block will slide along the guide rail until the block is blocked by the limit block and cannot move. At this time, the electric push rod continues to pull the movable plate to move, and the movable plate moves along the back of the four sets of guide columns. Move toward the block, break away from the contact with the block, and the movable plate stretches four sets of springs. At the same time, the movable plate drives the magnet column to retract into the rectangular slot, releasing the adsorption effect of the magnet column on the chain plate, so that one set of chain plates falls into the flow channel between the first guide strip and the second guide strip, and the other set of chain plates falls into the flow channel inside the third guide strip. The two sets of chain plates slide along the corresponding flow channels into the cavities on both sides of the discharge box, so that the chain plates and the pin shafts are placed separately, thereby realizing the classification of the chain plates and the pin shafts, which is convenient for the staff to handle the chain plates and the pin shafts later.

[0012] 3. When a set of electric push rods drives the corresponding stop blocks to move, the movable plate on the stop blocks drives the corresponding racks to slide along the guide holes, and the moving racks drive another set of racks to move through gears, and the other set of racks drives another set of stop blocks to move synchronously, thereby achieving the above-mentioned distance from or blocking of the opening grooves. Therefore, only one set of electric push rods is needed to achieve the synchronous movement of the two sets of stop blocks. By setting gears and two sets of racks, it is not only more convenient for the staff to debug, but also reduces the failure rate of the device. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0024] In order to make the technical means, creative features, achieved purposes, and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0025] Example 1: As Figures 1 to 3 shown, a chain processing and cutting device according to an embodiment of the present invention includes a machine base 1, a frame 2 is provided on the machine base 1, a chain passing groove 3 for placing a chain 9 is formed on the frame 2, and a sprocket 4 for engaging the chain 9 is rotatably installed in the chain passing groove 3. Support plates 5 are symmetrically arranged on both sides of the frame 2, and a material blocking mechanism 7 is installed on the support plates 5. The material blocking mechanism 7 includes a sliding seat 701, the sliding seat 701 is movably installed on a group of support plates 5, a cylinder 702 fixedly connected to one end of the sliding seat 701, the cylinder 702 is fixedly installed on a group of support plates 5, two groups of pressing pin heads 703 fixedly installed on the other end of the sliding seat 701, two opening grooves 301 are symmetrically formed on both sides of the chain passing groove 3, two groups of material blocking blocks 704 are respectively inserted into the two opening grooves 301, two avoiding holes 41 for the pressing pin heads 703 to pass through are formed on the material blocking blocks 704, an electric push rod 705 for driving the material blocking blocks 704, the electric push rod 705 is fixedly installed on the support plate 5, a vibration motor 6 is fixedly installed on a group of support plates 5, and a feeding box 8 is arranged at the lower end of the chain passing groove 3.

[0026] Specifically, the diameter of the avoidance hole 41 is slightly larger than the diameter of the end of the pressing pin head 703. In the initial state, the two groups of blocking blocks 704 respectively block the two groups of opening grooves 301. When the chain 9 needs to be cut, the chain 9 is placed in the chain groove 3, and the chain 9 is meshed with the sprocket 4 in the chain groove 3. At the same time, the two groups of chain plates at the ends of the chain 9 are respectively facing the two groups of blocking blocks 704. Then, the sprocket 4 is driven to rotate by the motor, and the sprocket 4 drives the chain 9 to slide obliquely downward along the chain groove 3. The number of revolutions of the fixed sprocket 4 controls the length of the chain 9, thereby fixing the length of the cut chain 9, and then the sliding seat 701 together with the two sets of pressing pin heads 703 are pushed toward the chain 9 by the cylinder 702. During this process, the two sets of pressing pin heads 703 will respectively pass through the two sets of avoidance holes 41 on one set of blocking blocks 704, and will press against the two sets of pin shafts on the chain 9 until the pin shafts are separated from the chain 9, and the two sets of pressing pin heads 703 will push the pin shafts through the two sets of avoidance holes on the other set of blocking blocks 704. 41 is pushed out and falls onto another set of support plates 5. The pin shaft will roll down along the other set of support plates 5 into the material discharge box 8. Then the two sets of pressing pin heads 703 are withdrawn, and the two sets of electric push rods 705 are started. The electric push rods 705 drive the blocking block 704 away from the opening slot 301. Then the vibration motor 6 is started. The vibration generated by the vibration motor 6 causes the chain plate to fall from the opening slot 301 onto the support plate 5, and slide along the support plate 5 into the material discharge box 8. At the same time, under the action of vibration, the cut chain 9 will move along the opening slot 301. Continue to slide obliquely downward through the chain groove 3 until it falls onto the machine base 1, and then make the two groups of blocking blocks 704 block the two groups of open grooves 301 again, repeat the above operation, and cut the chain 9 for the next time. Compared with the prior art, during the cutting process of the chain 9, the pin shaft and chain plate generated by the cutting will be automatically recovered into the discharge box 8 in the present solution, thereby avoiding the pin shaft and chain plate from affecting the cutting of the chain 9 for the next time, which not only improves the automation rate of the device, but also improves the cutting efficiency of the chain 9.

[0027] Furthermore, two groups of guide grooves 501 are formed on a group of support plates 5 , and two groups of slide rails 7011 are formed on the lower end surface of the slide seat 701 , and the slide rails 7011 are slidably connected to the guide grooves 501 .

[0028] Specifically, when the cylinder 702 pushes the sliding seat 701 to move, the sliding seat 701 drives the two sets of slide rails 7011 to slide along the two sets of guide grooves 501 respectively, and the cooperation between the slide rails 7011 and the guide grooves 501 guides the movement of the sliding seat 701.

[0029] like Figures 4 to 6As shown, the material blocking block 704 includes a block body 7041, the block body 7041 is movably inserted into the opening groove 301, a movable plate 7042 provided on one side of the block body 7041, the output end of the electric push rod 705 is connected to the movable plate 7042, four sets of guide posts 7043 movably inserted on the movable plate 7042, springs 7044 sleeved on the guide posts 7043, one end of a magnet post 7045 is fixedly connected to the movable plate 7042, four sets of installation grooves 412 are formed on the block body 7041, one ends of the four sets of guide posts 7043 are respectively fixedly installed in the four sets of installation grooves 412, one ends of the four sets of springs 7044 are all fixedly connected to the movable plate 7042, the other ends of the four sets of springs 7044 are respectively fixedly connected to the bottoms of the four sets of installation grooves 412, a rectangular insertion slot 411 is formed on the block body 7041, the magnet post 7045 is movably inserted into the rectangular insertion slot 411, a chute 413 is formed on one side of the lower end of the block body 7041, the chute 413 is slidably connected to a guide rail 505, a limit block 5051 for blocking the block body 7041 is provided at one end of the guide rail 505, a third material guiding strip 504 is provided on one set of support plates 5, a first material guiding strip 502 and a second material guiding strip 503 are provided on the other set of support plates 5, and two sets of partition plates 801 are provided in the material placing box 8.

[0030] Specifically, the block 7041 and the movable plate 7042 are made of aluminum alloy. The two groups of partitions 801 divide the discharge box 8 into three groups of cavities. The first guide strip 502 and the second guide strip 503 divide the upper end surface of the other group of support plates 5 into two groups of flow channels. During the cutting process of the above-mentioned chain 9, the pin shaft and the chain plate will be automatically recovered into the discharge box 8, so that the recovered pin shaft and chain plate are mixed together, which makes the subsequent processing of the staff more troublesome. Therefore, the above-mentioned two groups of pressing pins are When the head 703 pushes the pin out from the two sets of avoidance holes 41 on the other set of blocking blocks 704, the pin will fall into the flow channel inside the second guide strip 503, so that the pin will roll along the flow channel into the cavity located in the middle area of the discharge box 8. When the electric push rod 705 drives the blocking block 704 away from the opening groove 301, the magnet column 7045 will attract the chain plate, so that the chain plate will be separated from the chain groove 3 along with the blocking block 704. At the same time, the lower end of the block 7041 The slide groove 413 will slide along the guide rail 505 until the block 7041 is blocked by the limit block 5051 and cannot move. At this time, the electric push rod 705 continues to pull the movable plate 7042 to move, and the movable plate 7042 moves along the four groups of guide pillars 7043 back to the block 7041, breaking away from the contact with the block 7041, and the movable plate 7042 stretches the four groups of springs 7044. At the same time, the movable plate 7042 drives the magnet column 7045 to retract into the rectangular slot 411, releasing the adsorption effect of the magnet column 7045 on the chain plate, so that one group of chain plates falls into the flow channel between the first guide strip 502 and the second guide strip 503, and the other group of chain plates falls into the flow channel inside the third guide strip 504, and the two groups of chain plates slide along the corresponding flow channels into the cavities on both sides of the material discharge box 8, so that the chain plates and the pin shafts are placed separately, so as to realize the classification of the chain plates and the pin shafts, and facilitate the subsequent processing of the chain plates and the pin shafts by the staff.

[0031] Embodiment 2: Figures 7 to 9 As shown, compared with Example 1, another embodiment of the present invention is: the material blocking mechanism 7 also includes a linkage mechanism 706, the linkage mechanism 706 includes a gear 7061, the gear 7061 is rotatably installed in the frame 2, two groups of racks 7062 are meshed with the gear 7061, one end of the two groups of racks 7062 are respectively connected to two groups of movable plates 7042, a rectangular cavity 201 is opened in the frame 2, the gear 7061 is rotatably installed in the rectangular cavity 201, guide holes 202 are opened on both sides of the base 1, the guide holes 202 are connected to the rectangular cavity 201, and the racks 7062 are movably plugged into the guide holes 202.

[0032] Specifically, the above-mentioned two groups of blocking blocks 704 are driven by two groups of electric push rods 705 respectively. During assembly and debugging, the two groups of blocking blocks 704 need to be debugged respectively, which makes the assembly more troublesome. Secondly, as long as one group of electric push rods 705 fails, the entire device cannot operate, which increases the failure rate of the device. When one group of electric push rods 705 drives the corresponding blocking block 704 to move, the movable plate 7042 on the blocking block 704 drives the corresponding rack 7062 to slide along the guide hole 202, and the moving rack 7062 drives the other group of racks 7062 to move through the gear 7061, and the other group of racks 7062 drives the other group of blocking blocks 704 to move synchronously, thereby achieving the above-mentioned distance from or blocking of the opening groove 301. Therefore, only one group of electric push rods 705 is needed to achieve the synchronous movement of the two groups of blocking blocks 704. By setting the gear 7061 and the two groups of racks 7062, not only is it more convenient for the staff to debug, but also the failure rate of the device is reduced.

[0033] Working principle: put the chain 9 into the chain slot 3, and make the chain 9 mesh with the sprocket 4 in the chain slot 3, and at the same time, the two groups of chain plates at the ends of the chain 9 are respectively facing the two groups of stop blocks 704, and then the sprocket 4 is driven by the motor to rotate, and the sprocket 4 drives the chain 9 to slide obliquely downward along the chain slot 3, and by setting the number of revolutions of the sprocket 4, the moving length of the chain 9 is controlled, so that the cut chain 9 is fixed in length, and then the sliding seat 701 is pushed by the cylinder 702 together with the two groups of pressing pin heads 703 to move toward the direction of the chain 9. In this process, the two groups of pressing pin heads 703 will respectively pass through the two groups of avoidance holes 41 on a group of stop blocks 704, and will press against the two groups of pin shafts on the chain 9 until the pin shafts are separated from the chain 9, and the two groups of pressing pin heads 703 will press the pin shafts Push out from the two sets of avoidance holes 41 on the other set of blocking blocks 704 and fall onto the other set of support plates 5. The pin shaft will roll down along the other set of support plates 5 into the material discharge box 8. Then withdraw the two sets of pressing pin heads 703, start the two sets of electric push rods 705, and the electric push rods 705 drive the blocking blocks 704 away from the opening slots 301. Then start the vibration motor 6. The vibration generated by the vibration motor 6 causes the chain plate to fall from the opening slot 301 onto the support plate 5, and slide along the support plate 5 into the material discharge box 8. At the same time, under the action of vibration, the cut chain 9 will continue to slide obliquely downward along the chain slot 3 until it falls onto the machine base 1. Then the two sets of blocking blocks 704 will block the two sets of opening slots 301 again. Repeat the above operation to cut the chain 9 for the next time. During the cutting process of the chain 9, the pin shaft and the chain plate will be automatically recovered into the discharge box 8, so that the recovered pin shaft and the chain plate are mixed together, which makes the subsequent processing of the staff more troublesome. Therefore, when the two groups of pin pressing heads 703 push the pin shaft out from the two groups of avoidance holes 41 on the other group of blocking blocks 704, the pin shaft will fall into the flow channel inside the second guide strip 503, so that the pin shaft will roll along the flow channel to the cavity located in the middle area of the discharge box 8. When the electric push rod 705 drives the blocking block 704 away from the open groove 301, the magnet column 7045 will attract the chain plate, so that the chain plate will be separated from the chain groove 3 along the blocking block 704, and at the same time, the slide groove 413 at the lower end of the block 7041 will slide along the guide rail 505 until the block 7041 is restricted. The block 5051 blocks and cannot move. At this time, the electric push rod 705 continues to pull the movable plate 7042 to move. The movable plate 7042 moves along the four groups of guide pillars 7043 away from the block 7041, and is out of contact with the block 7041. The movable plate 7042 stretches the four groups of springs 7044. At the same time, the movable plate 7042 drives the magnet column 7045 to retract into the rectangular slot 411, releasing the adsorption effect of the magnet column 7045 on the chain plate, so that one group of chain plates falls into the flow channel between the first guide strip 502 and the second guide strip 503, and the other group of chain plates falls into the flow channel inside the third guide strip 504. The two groups of chain plates slide along the corresponding flow channels into the cavities on both sides of the material discharge box 8, so that the chain plates and the pin shafts are placed separately. When a group of electric push rods 705 drives the corresponding stop blocks 704 to move, the movable plate 7042 on the stop blocks 704 drives the corresponding racks 7062 to slide along the guide holes 202, and the moving racks 7062 drive another group of racks 7062 to move through the gears 7061, and the other group of racks 7062 drives another group of stop blocks 704 to move synchronously, thereby achieving the above-mentioned distance from or blocking of the opening groove 301.
