Description

Technical Field

[0001] This invention relates to the field of flooring processing technology, and more particularly to a groove processing device for wooden flooring. Background Technology

[0002] In the manufacturing process of wooden flooring, to ensure that the planks can be seamlessly joined and tightly connected, it is usually necessary to precisely machine protruding tongues and corresponding grooves on the four sides of the flooring, namely the two long sides and the two short sides. This tongue and groove design is the key to the flooring's locking function, and its machining precision directly affects the flatness of the installed ground, the strength of the connection, and the overall moisture resistance.

[0003] Currently, the industry generally relies on specialized equipment for processing floor grooves. The common practice is to separate the grooving operations of the long side (along the length of the floor) and the short side (along the width of the floor) into two independent processes, which are completed by two separate machines: a "long side grooving machine" for processing the long side and a "short side grooving machine" for processing the short side.

[0004] However, this separate equipment arrangement also presents some obvious problems: the two machine tools are relatively large, and a complex conveying and transfer system is often required to achieve material transfer and connection. This not only occupies a lot of production workshop space, resulting in a scattered and less compact layout of the entire production line, but also means higher equipment investment and subsequent maintenance costs. In addition, this process relies heavily on manual operation, increasing the labor burden and labor demand of workers, making it difficult to achieve a highly efficient and intensive modern production model. Summary of the Invention

[0005] In order to overcome the shortcomings mentioned in the background art, the present invention provides a groove processing device for wooden flooring.

[0006] The technical solution is as follows: A groove processing device for wooden flooring includes a housing. A first transmission module symmetrically distributed within the housing is mounted, with uniformly distributed mounting plates on the first transmission module. A pressing belt for stabilizing materials is installed within the housing. First grooving modules are mounted on both sides of the pressing belt within the housing. A second and third transmission modules, located below the first transmission modules, are mounted on the housing, with different transmission speeds. A fixing plate is fixedly connected within the housing, and several guide rollers are rotatably connected to the fixing plate. The fixing plate has symmetrically distributed mounting blocks, each mounting block having a second grooving module mounted on it. An automatic extrusion module is mounted above the fixing plate within the housing, used for extruding and positioning the material. An upper clamping mechanism is provided on the mounting plates, and a lower clamping mechanism is provided on the fixing plate. Both the upper and lower clamping mechanisms are used to fix the material.

[0007] Furthermore, the upper clamping mechanism includes two symmetrically distributed clamping plates, which are slidably connected to adjacent mounting pieces and are provided with a first compression spring between them. The clamping plates are hinged to connecting rods, and the two connecting rods are hinged together to a fixed shell. A piston rod is slidably connected inside the fixed shell, and a first elastic element is provided between the two.

[0008] Furthermore, a guide ring is fixedly connected inside the housing, and the guide ring is used to guide all the piston rods.

[0009] Furthermore, the lower clamping mechanism includes: two pairs of fixing blocks, each disposed on the fixing plate; and two pairs of clamping strips, respectively fixed to adjacent fixing blocks, wherein the clamping strips are fixed to the corresponding mounting blocks.

[0010] Furthermore, it also includes a pre-positioning mechanism, disposed within the housing, for guiding materials on the second and third transmission modules. The pre-positioning mechanism includes: fixed rods, symmetrically distributed and fixedly connected within the housing, each fixed rod hinged to a first guide rod; an air supply module, installed within the housing, the air outlet of which is connected to an air guide pipe; and a first housing, symmetrically distributed and fixedly connected within the housing, the first housing having a first sliding rod slidably connected therein, with an air bladder between them. The air guide pipe communicates with the air bladder within the first housing, and the first sliding rod is fixedly connected to the adjacent first guide rod.

[0011] Furthermore, symmetrically distributed transition shells are fixedly connected to the air guide tube. The transition shells isolate and communicate with the air guide tube. A sealing plate and a transition plate are slidably connected inside the transition shells, and a second elastic element is provided between the sealing plate and the transition plate.

[0012] Furthermore, it also includes a repositioning mechanism, disposed within the housing, for guiding the materials on the second and third transmission modules again. The repositioning mechanism includes: second guide rods, symmetrically distributed and respectively hinged to adjacent clamping bars; an air storage shell, fixed within the housing and connected to the air duct; a pair of clamping bars near the second guide rods, each fixedly connected to a second housing; the second housing is slidably connected to a second sliding rod, and an air bladder is disposed between the two; the air bladder in the second housing is connected to the air storage shell through a conduit; and the second sliding rod is fixedly connected to the adjacent second guide rod.

[0013] Furthermore, symmetrically distributed extrusion strips are fixed inside the housing. The extrusion strips are elastic and located on the upper side of the first transmission module. The distance between the symmetrically distributed extrusion strips gradually increases from the side closer to the pressing belt to the other side.

[0014] Furthermore, a guide plate is fixedly connected inside the housing, and the guide plate is located between the symmetrically distributed first transmission modules, with the height of the middle part of the guide plate being greater than the height of its two sides.

[0015] Furthermore, a plurality of extrusion blocks are slidably connected inside the housing. Each pair of fixed blocks and symmetrically distributed mounting blocks are respectively fitted with the corresponding extrusion blocks. The housing is threadedly connected to a transmission rod, and the transmission rod is rotatably connected to a drive plate. The drive plate is used to drive all the extrusion blocks to move. The mounting blocks and the fixed blocks are slidably connected to the fixed plate, and a second compression spring is fixed between the fixed blocks and the housing.

[0016] The beneficial effects of the present invention are as follows: The present invention performs grooving operation on the short side of the material during the movement of the material on the upper side of the first transmission module, and performs grooving operation on the long side of the material during the movement of the material on the lower side of the first transmission module. In this way, the grooving operations of the long and short sides are integrated into one device, making the entire grooving process smoother and saving the space occupied by the device.

[0017] This invention uses symmetrically distributed clamping plates on the same mounting plate to clamp the material, and in conjunction with the squeezing of the pressing belt, to fix the material in multiple directions, ensuring the stability of the material during the grooving process and ensuring the processing accuracy of the material.

[0018] This invention uses symmetrically distributed first guide rods and symmetrically distributed second guide rods to position and guide materials, correct the state of materials during movement, and facilitate the smooth entry of materials into the symmetrically distributed clamping strips.

[0019] The present invention buffers the compressive force on the first guide rod by moving the sealing plate and the transition plate relative to each other, thereby reducing the relative compressive force between the material and the first guide rod and ensuring the integrity of the material.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments. The internal structure of the housing 1 in the accompanying drawings is only schematic. The installation method of all internal parts can be adjusted according to the actual situation, such as by fixing with a bracket.

[0023] Research has found that existing wood flooring grooving devices are divided into long-side grooving machines and short-side grooving machines. This means that two separate pieces of equipment are needed to groove the long and short sides of the wood flooring. In order to achieve material transfer and connection, a complex conveying and transfer system is usually required. During the process, the wood flooring is very prone to tilting, which affects the subsequent grooving accuracy and also leads to an excessively long production line and low grooving efficiency.

[0024] Example 1 A groove processing device for wooden flooring, such as Figures 1-6 As shown, the device includes a housing 1, inside which are two symmetrically distributed first transmission modules 3. The first transmission modules 3 are existing belt conveyors. The two first transmission modules 3 share a single servo motor for drive, and the conveyor belt on the first transmission module 3 moves counter-clockwise (within a certain direction). Figure 2 (Based on the front view perspective), the conveyor belt of the first transmission module 3 is equipped with evenly distributed mounting plates 4. A pressing belt 5 for stabilizing the material is installed inside the housing 1. The pressing belt 5 is used to compress the material being grooved, keeping it stable during the grooving process. The pressing belt 5 is located on the left side of the first transmission module 3. First grooving modules 6 are installed on both the front and rear sides of the pressing belt 5 inside the housing 1. The first grooving modules 6 are used to groove the short side of the material. The two first grooving modules 6 respectively process tenons and grooves, and both are existing equipment. The housing 1 is equipped with mounting plates 4 evenly distributed on the conveyor belt of the first transmission module 3. The second transmission module 7 and the third transmission module 8 are located below module 3, and their transmission speeds are different. Both the second transmission module 7 and the third transmission module 8 correspond to the left half of the first transmission module 3. The second transmission module 7 and the third transmission module 8 work simultaneously to change the orientation of the material on them. A fixed plate 9 is fixedly connected inside the housing 1, located below the first transmission module 3. The fixed plate 9 corresponds to the right half of the first transmission module 3. Several guide rollers 901 are rotatably connected to the fixed plate 9. The guide rollers 901 are used to guide the moving material. The fixed plate 9 has two symmetrically distributed guide rollers... Mounting block 10 (in this embodiment, mounting block 10 is fixedly connected to fixing plate 9) is equipped with a second grooving module 101. The second grooving module 101 is used to groove the long side of the material, and the two second grooving modules 101 respectively process tenons and grooves. The second grooving module 101 is an existing device. An automatic extrusion module 11 is installed inside the housing 1 above the fixing plate 9. The automatic extrusion module 11 consists of a servo motor, a sprocket drive mechanism, and three extrusion rollers. Its servo motor drives all the extrusion rollers to rotate through the sprocket drive mechanism. 11 is used to squeeze and position the material to ensure the stability of the material during the grooving operation on its long side. The mounting plate 4 is equipped with an upper clamping mechanism and the fixing plate 9 is equipped with a lower clamping mechanism. Both the upper and lower clamping mechanisms are used to fix the material. By grooving the short side of the material when it moves above the first transmission module 3, and grooving the long side of the material when it moves below the first transmission module 3, the grooving operations on the long and short sides are integrated into one device, making the entire grooving process smoother and saving the space occupied by the device.

[0025] like Figure 7 and Figure 8As shown, the upper clamping mechanism includes two symmetrically distributed clamping plates 21. Each clamping plate 21 has evenly distributed rubber protrusions on its opposite sides to improve material stability. The clamping plates 21 are slidably connected to adjacent mounting pieces 4, and a first compression spring is provided between them. A connecting rod 22 is hinged to the clamping plates 21, and the two connecting rods 22 are hinged together to a fixed housing 23. An exhaust hole is provided on the side of the fixed housing 23 near the connecting rod 22, allowing the piston rod 24 to slide smoothly. The piston rod 24 is slidably connected inside the fixed housing 23, and a first elastic element, which is a spring, is provided between them. Figure 8 The first elastic element shown is in a compressed state. The elastic coefficient of the first compression spring on the clamping plate 21 is less than the elastic coefficient of the first elastic element on the piston rod 24.

[0026] like Figure 7 , Figure 8 and Figure 13 As shown, a guide ring 25 is fixedly connected inside the housing 1. The guide ring 25 is used to guide all the piston rods 24. The guide ring 25 has a first guide portion 251, a second guide portion 252 and a third guide portion 253. The second guide portion 252 corresponds to the pressing belt 5. The height of the left part of the lower side of the guide ring 25 is higher than the height of its right part. When the piston rod 24 slides at the first guide portion 251 and the third guide portion 253, the piston rod 24 is located inside the fixed housing 23. When the piston rod 24 slides at the second guide portion 252, the piston rod 24 extends out of the fixed housing 23.

[0027] like Figures 4-6 , Figure 11 and Figure 12 As shown, the lower clamping mechanism includes: two pairs of fixing blocks 31, both of which are disposed on the fixing plate 9, and the two pairs of fixing blocks 31 are respectively located on the left and right sides of the two mounting blocks 10; two pairs of clamping strips 32, which are respectively fixed to the adjacent fixing blocks 31, and each pair of clamping strips 32 is used to clamp the material, and the clamping strips 32 are fixed to the corresponding mounting block 10.

[0028] The working principle of this embodiment: When using this device to perform grooving operations on materials, activate the two first transmission modules 3, the second transmission module 7, the third transmission module 8, the automatic extrusion module 11, all the first grooving modules 6, and all the second grooving modules 101. The first transmission module 3 starts working and drives all the mounting plates 4 on it to move. The mounting plates 4 drive the parts on them to move synchronously. Then, place all the materials in sequence on the two corresponding mounting plates 4 on the two first transmission modules 3, and position the materials between the two clamping plates 21. At this time, the short sides of the materials face the front and back sides respectively.

[0029] During the movement of mounting plate 4 (taking one as an example), mounting plate 4 drives the two clamping plates 21 and two connecting rods 22 on it to move the fixing shell 23. The fixing shell 23 drives the piston rod 24 to move along the first guide portion 251 of the guide ring 25. As the piston rod 24 moves, when the piston rod 24 moves to the second guide portion 252 of the guide ring 25, the guide ring 25 pulls the piston rod 24, causing the piston rod 24 to move downward. The piston rod 24 drives the fixing shell 23 downward through the first elastic element. The two connecting rods 22 drive the two clamping plates 21 to move, causing the two clamping plates 21 to move towards each other and compress the first compression spring on them. The two clamping plates 21 clamp the material. After the clamping plates 21 come into contact with the material, the clamping plates 21 stop moving relative to the mounting plate 4. At this time, the piston rod 24 continues to move downward and begins to compress the first elastic element on it. Through the compression of the first elastic element, the two clamping plates 21 always have a force to clamp the material, thereby ensuring the stability of the material during the movement process. During this process, the material moves from right to left.

[0030] After the clamping plate 21 fixes the material, as the first transmission module 3 continues to work, the material comes into contact with the pressing belt 5, and the material will drive the pressing belt 5 to move. At the same time, the pressing belt 5 squeezes the upper side of the material, which further improves the stability of the material during movement. Then, when the short side of the material comes into contact with the first grooving module 6, the first grooving module 6 performs grooving on the short side of the material. During this process, the pressing belt 5 always squeezes the material, and the clamping plate 21 always clamps and fixes the material, thereby ensuring the stability of the material during the grooving process and ensuring the processing accuracy of the material.

[0031] After the material passes through the first slotting module 6, the short side of the material is slotted and continues to move. As the first transmission module 3 continues to work, the material first loses contact with the pressing belt 5, and then the material moves to the lower side of the first transmission module 3. When the piston rod 24 moves to the third guide part 253 of the guide ring 25, the piston rod 24 continues to move along the third guide part 253 of the guide ring 25. After that, the guide ring 25 pushes the piston rod 24, causing the piston rod 24 to gradually retract into the fixed shell 23 and no longer squeeze the first elastic element. After the first elastic element returns to its original state, the piston rod 24 drives the fixed shell 23 to start moving through the first elastic element. The fixed shell 23 pushes the two clamping plates 21 through the two connecting rods 22 respectively, causing the two clamping plates 21 to move in opposite directions. The clamping plates 21 lose the squeezing of the first compression spring on them and lose the clamping and fixing of the material.

[0032] After the two clamping plates 21 move in opposite directions, the material falls onto the second transmission module 7 and the third transmission module 8 under the action of gravity. The second transmission module 7 and the third transmission module 8 jointly drive the material to move. During this process, the material moves from left to right. Due to the speed difference between the second transmission module 7 and the third transmission module 8, the material gradually deflects, so that the two long sides of the material face the front and back sides respectively. Then, the material continues to move and enters between the two clamping bars 32. The clamping bars 32 clamp the long sides of the material to keep the material stable during the movement.

[0033] When the material enters between the two clamping bars 32, it comes into contact with the automatic extrusion module 11. The automatic extrusion module 11 extrudes the material and drives it to continue moving. The material moves along several guide rollers 901. When the material comes into contact with the two second grooving modules 101, the second grooving modules 101 grooves the long side of the material. During this process, the automatic extrusion module 11 always extrudes the material to ensure the stability of the material during the grooving process and to ensure the processing accuracy of the material.

[0034] After the material passes through the two second grooving modules 101, the long side grooving operation of the material is completed. The automatic extrusion module 11 continues to transmit the material until the material is removed from the housing 1. At this time, the grooving operation of the material is completed, and the above operation is repeated to continue processing the subsequent materials. After all materials have been processed, the two first transmission modules 3, the second transmission module 7, the third transmission module 8, the automatic extrusion module 11, all the first grooving modules 6 and all the second grooving modules 101 are shut down.

[0035] Example 2 Based on Embodiment 1, this embodiment proposes a function to position the material on the second transmission module 7 and the third transmission module 8, thereby facilitating the smooth entry of the material between the two clamping bars 32, such as... Figures 4-6 and Figure 9As shown, it also includes a pre-positioning mechanism, housed within the casing 1, for guiding materials on the second transmission module 7 and the third transmission module 8. The pre-positioning mechanism includes: two fixed rods 41, symmetrically distributed, both fixed within the casing 1; each fixed rod 41 is hinged to a first guide rod 42, which guides the materials and facilitates switching of material placement methods; the first guide rod 42 is equipped with an array of rollers to reduce wear on the materials; and an air supply module 43, installed within the casing 1. The air supply module 43 is a pre-positioning mechanism. Some air pumps have an air outlet connected to an air guide pipe 44; there are two first housings 45, which are symmetrically distributed and fixedly connected to the housing 1. A first slide rod 46 is slidably connected inside the first housing 45, and an airbag (not shown in the figure) is provided between the two. Both the first housing 45 and the first slide rod 46 are arc-shaped. During the expansion of the airbag, the first slide rod 46 is pushed to move. During the contraction of the airbag, the first slide rod 46 can be moved. The air guide pipe 44 is connected to the airbag inside the first housing 45, and the first slide rod 46 is fixedly connected to the adjacent first guide rod 42.

[0036] like Figure 5 and Figure 9 As shown, symmetrically distributed transition shells 51 are fixed to the gas guide pipe 44. The two transition shells 51 correspond to the two first shells 45 respectively. The transition shells 51 isolate the gas guide pipe 44 and connect it to the gas guide pipe. A sealing plate 52 is slidably connected inside the transition shell 51, and a second elastic element, which is a spring, is provided between the two. The sealing plate 52 buffers the pressure of the gas in the gas guide pipe 44 near the first shell 45 through the second elastic element, so that the first guide rod 42 can move after being squeezed by the material, thereby avoiding the material from being squeezed hard against the first guide rod 42.

[0037] Following the working principle of Embodiment 1, during the process of the material deflection jointly driven by the second transmission module 7 and the third transmission module 8, the deflection angle and direction of movement of the material cannot be guaranteed, making it difficult for the material to smoothly enter between the two clamping bars 32. To avoid this problem, the specific operation is as follows: When the second transmission module 7 and the third transmission module 8 are activated, the air supply module 43 is activated. The air supply module 43 injects air into the two transition shells 51 through the air guide pipe 44. The gas in the transition shell 51 pushes the sealing plate 52 inside to move upward. The sealing plate 52 pushes the transition plate 53 on it to move upward through the second elastic element. The transition plate 53 pushes the gas on it into the airbag in the corresponding first shell 45, causing the airbag in the first shell 45 to start to inflate. The airbag gradually pushes the adjacent first sliding rod 46. The first sliding rod 46 pushes the adjacent first guide rod 42, causing the first guide rod 42 to rotate around the adjacent fixed rod 41. The first guide rod 42 gradually becomes inclined (e.g., Figure 9As shown), the two first guide rods 42 move in opposite directions, gradually reducing the distance between the left ends of the two first guide rods 42 until the distance between the left ends of the two first guide rods 42 is consistent with the length of the short side of the material. At this point, the air supply module 43 is stopped, that is, the first guide rods 42 stop rotating.

[0038] During the process of the second transmission module 7 and the third transmission module 8 moving the material to the right, when the material comes into contact with the first guide rod 42, the first guide rod 42 guides the material, causing the material to gradually move towards the center of the second transmission module 7 and the third transmission module 8. After the material comes into contact with the left ends of both first guide rods 42, the material continues to move and enters between the left ends of the two first guide rods 42. The two first guide rods 42 jointly clamp and position the material, so that the two long sides of the material always face the front and rear sides respectively. As the second transmission module 7 and the third transmission module 8 work, they continue to move the material to the right until the material enters between the two clamping bars 32.

[0039] After all materials have been slotted, the gas in all the airbags in the first housing 45 is extracted by controlling the air supply module 43, and the two first guide rods 42 are reset.

[0040] During the movement of materials driven by the second transmission module 7 and the third transmission module 8, when the material comes into contact with one of the first guide rods 42, if the material squeezes the first guide rod 42 or gets stuck between the two first guide rods 42, the first guide rod 42 swings (obstructs an abnormal tilt). The first guide rod 42 squeezes the adjacent airbag through the first slide rod 46. At the same time, the gas in the airbag flows back to the upper part of the first shell 45, and the air pressure in the upper part of the first shell 45 increases. The gas at this position pushes the transition plate 53 to move downward and compress the adjacent second elastic element. In this way, the relative movement of the transition plate 53 and the sealing plate 52 buffers the squeezing force on the first guide rod 42, preventing the material from being hard squeezed against the first guide rod 42 and causing damage to the material. After the material passes the first guide rod 42 smoothly, the transition plate 53 moves upward under the action of the second elastic element, so that the first guide rod 42 returns to its normal tilt state.

[0041] Example 3 Based on Example 2, such as Figure 9 and Figure 10As shown, it also includes a repositioning mechanism, housed within the housing 1, for guiding the materials on the second transmission module 7 and the third transmission module 8 again. The repositioning mechanism includes: two second guide rods 61, symmetrically distributed, respectively hinged to the left side of adjacent clamping bars 32; the second guide rods 61 guide the materials to facilitate their entry between the two clamping bars 32; and an air storage shell 62, fixed within the housing 1 and connected to the air duct 44, with a second shell fixed to the left side of the left clamping bar 32. 63. The second shell 63 is slidably connected to the second slide rod 64, and an airbag (not shown in the figure) is provided between the two. Both the second shell 63 and the second slide rod 64 are arc-shaped. The airbag is used to push the first slide rod 46 to move along the second shell 63. The two sides of the airbag are fixedly connected to the second shell 63 and the second slide rod 64 respectively. That is, when the airbag contracts, it can drive the second slide rod 64 to return to its original position. The airbag in the second shell 63 is connected to the air storage shell 62 through a conduit. The second slide rod 64 is fixedly connected to the adjacent second guide rod 61.

[0042] The working principle of this embodiment: Following the working principle of Embodiment 2, when the gas supply module 43 is activated, it injects gas into the gas storage shell 62 through the gas guide pipe 44. The gas in the gas storage shell 62 enters the air bladders on the two second shells 63 through the pipes, causing the air bladders to inflate. The air bladders push the adjacent second sliding rods 64, which move and push the adjacent second guide rods 61 to swing, causing the two second guide rods 61 to swing in opposite directions until the two second guide rods 61 are respectively aligned with the adjacent clamping bars 32. At this point, the two first guide rods 42 also move to the appropriate position (e.g., Figure 10 As shown), at this time, the air supply module 43 is turned off, and the material passing through the two first guide rods 42 is received by the two second guide rods 61, and the material is guided and positioned again to further facilitate its entry between the two clamping bars 32.

[0043] After the material processing is completed, the gas in the air bladders on all the second housings 63 is extracted by controlling the gas supply module 43, and the two second guide rods 61 are reset. During this process, the two first guide rods 42 are reset synchronously.

[0044] Example 4 like Figure 2 , Figure 3 and Figure 7 As shown, two symmetrically distributed extrusion strips 71 are fixed inside the housing 1. The extrusion strips 71 are elastic, similar to spring plates. The extrusion strips 71 are located on the upper side of the first transmission module 3 and on the right side of the pressing belt 5. The distance between the two extrusion strips 71 gradually increases from left to right. The two extrusion strips 71 are used to guide the material on the mounting plate 4, so that the material is placed in the center on the corresponding two mounting plates 4, which improves the accuracy of grooving the material and reduces the difficulty of manual operation.

[0045] Example 5 like Figure 2 and Figure 3 As shown, a guide plate 81 is fixed inside the housing 1. The guide plate 81 is located below the pressing belt 5. When the short side of the material is slotted, the debris generated by the material will fall down onto the guide plate 81. The height of the middle part of the guide plate 81 is greater than the height of its front and rear sides. The guide plate 81 guides this part of the debris and disperses it to the front and rear sides of the first transmission module 3, without affecting the subsequent processing. The guide plate 81 is located between the symmetrically distributed first transmission modules 3. The front and rear sides of the left side of the housing 1 are provided with discharge ports (not shown in the figure). The discharge ports are used to discharge the debris that slides down from the guide plate 81.

[0046] Example 6 like Figure 5 , Figure 6 , Figure 11 and Figure 12 As shown, three extrusion blocks 91 are slidably connected inside the housing 1. Each extrusion block 91 consists of an isosceles trapezoidal block and two square plates. The square plates are located below the isosceles trapezoidal blocks, and each square plate has an inclined groove that gradually slopes upward from left to right (this direction is based on...). Figure 12 (For reference), each pair of fixed blocks 31 and two mounting blocks 10 are respectively attached to the corresponding extrusion blocks 91. The right side of the housing 1 is threadedly connected to a transmission rod 92, and the left side of the transmission rod 92 is rotatably connected to a drive plate 93. The drive plate 93 is provided with three pairs of protrusions, which slide in the inclined grooves of the upper plate of the adjacent extrusion blocks 91. The drive plate 93 is used to drive all the extrusion blocks 91 to move. The fixed block 31 is slidably connected to the fixed plate 9, and a second compression spring is fixed between the fixed block 31 and the housing 1. The mounting block 10 is slidably connected to the fixed plate 9.

[0047] Before grooving the material, adjust the distance between the two symmetrically distributed clamping bars 32 according to the width of the material, so that the distance between the two clamping bars 32 corresponds to the width of the material. First, rotate the transmission rod 92. The transmission rod 92 moves into the machine housing 1 under the action of the thread. The transmission rod 92 drives the drive plate 93 to move to the right (towards...). Figure 12 As shown), the drive plate 93 drives the protrusions on it to move synchronously, and the protrusions squeeze the adjacent extrusion blocks 91, causing the extrusion blocks 91 to move downward. All the extrusion blocks 91 squeeze the corresponding two mounting blocks 10 and the corresponding two pairs of fixing blocks 31, causing the two mounting blocks 10 to move back to back. The mounting blocks 10 drive the second slotted module 101 on them to move synchronously, and at the same time, cause the two fixing blocks 31 in each pair of fixing blocks 31 to move back to back and compress the corresponding second compression spring. The two pairs of fixing blocks 31 drive the corresponding clamping strips 32 to move until the distance between the two symmetrically distributed clamping strips 32 corresponds to the width of the material, and then the transmission rod 92 stops rotating.

[0048] When it is necessary to reset the two second slotted modules 101 and all clamping bars 32, the transmission rod 92 is rotated in the opposite direction. At this time, the drive plate 93 drives all the pressing blocks 91 to move upward through the protrusion on it, that is, all the fixing blocks 31 and all the mounting blocks 10 lose their compression. Then, the fixing blocks 31 are reset under the action of the second compression spring on them. The fixing blocks 31 drive the corresponding clamping bars 32 to reset. The clamping bars 32 drive the second slotted module 101 to reset through the corresponding mounting blocks 10. Then, the transmission rod 92 is stopped from rotating.

They should not be used to limit the scope of protection of the present invention.
