Description

Technical Field

[0001] This invention relates to the field of block conveying structure technology, and more particularly to a U-shaped block conveying and forming device and method. Background Technology

[0002] U-shaped blocks are a commonly used type of precast blocks in construction engineering. Their conventional production process uses standard finished blocks as blanks and processes them into U-shaped grooves through mechanical milling to meet the needs of pipeline layout, structural node construction, and other applications in building construction.

[0003] Currently, the U-shaped block processing production line mainly includes a conveying mechanism and a separately set milling station. After the block blanks are transferred to the corresponding area of ​​the processing station by the conveying mechanism, they need to be transferred from the conveyor line to the processing workbench by a robot or manual handling and positioned and clamped. After the U-shaped groove milling is completed, the finished blocks are removed from the workbench and transferred to the subsequent stacking process.

[0004] However, the above processing mode is an intermittent operation. The two processes of blank conveying and milling are independent of each other, and the connection between the processes is not smooth, making it impossible to achieve continuous flow operation.

The two ends of the adjustment bracket are fixed to the two side beams. The spacing between the two sets of guide rollers is adjusted by adjusting the installation position on the adjustment bracket.

[0011] Furthermore, each of the guide roller groups includes a side support and multiple guide rollers; The guide rollers are all mounted on the side bracket via support shafts; The guide roller is rotatably mounted on the eccentric shaft section of the support shaft; the end of the support shaft protruding from the eccentric shaft section is rotatably mounted on the side bracket. A width detection unit is provided at the feed end of the guide roller assembly, and an adjustment drive is connected to the support shaft. The adjustment drive is used to drive the support shaft to rotate around its own axis.

[0012] Furthermore, the adjustment drive includes a rocker arm and a connecting bolt; One end of the swing arm is connected to the end of the support shaft that extends out of the side bracket, and the other end is fixedly connected to the connecting bolt; In the same group of guide rollers, at least one power source is connected to the corresponding connecting bolt on the multiple swing arms.

[0013] Furthermore, in the same group of guide rollers, the corresponding connecting bolts on multiple swing arms are connected to the power source through a linkage plate; The linkage plate includes a driving surface and a force-bending surface that bends and extends along the side of the driving surface and is connected to the power source; a strip-shaped hole is provided on the driving surface along the conveying direction, and a plurality of the connecting bolts are embedded in the strip-shaped hole; The force-bearing surface extends towards one side of the driving surface from both ends along the conveying direction to form a guide surface, and a sliding component is provided between the guide surface and the two end faces of the side bracket.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] like Figures 1-15 As shown, this application provides a U-shaped block conveying and forming device, including: a feeding conveying mechanism 1, a finished product conveying mechanism 2, and a processing conveying mechanism 3. The feeding conveying mechanism 1 is used to carry and convey block blanks; the finished product conveying mechanism 2 is used to carry and convey processed finished blocks; the processing conveying mechanism 3 is disposed between the feeding conveying mechanism 1 and the finished product conveying mechanism 2, and the processing conveying mechanism 3 includes: The power roller conveyor 31 is used to carry and drive the block blanks to be fed at a uniform speed and continuously. Two sets of guide rollers 32 are arranged on both sides of the power roller conveyor line 31; The lower pressure roller group 33 is correspondingly arranged above the power roller conveyor line 31; Two sets of guide rollers 32, a lower pressure roller 33 and a power roller conveyor line 31 form a guide channel. A tool assembly 4 for processing U-shaped grooves is provided on the transmission path of the power roller conveyor line 31 located in the guide channel.

[0022] In this invention, the device consists of a feeding conveyor 1, a processing conveyor 3, and a finished product conveyor 2 arranged sequentially along the block conveying direction. The conveying surfaces of these three mechanisms are flush and connected end-to-end, forming a continuous block conveying path. The input end of the feeding conveyor 1 is a blank feeding position, used to receive externally fed block blanks. Its output end precisely connects to the input end of the processing conveyor 3, ensuring a smooth transition of blocks to the processing conveyor 3. The input end of the finished product conveyor 2 connects to the output end of the processing conveyor 3, and its output end extends to the block stacking station, used to convey the processed U-shaped block finished products to the subsequent stacking process.

[0023] The top surfaces of the rollers on the power roller conveyor 31 together form a horizontal conveying working surface. The friction between the roller surfaces and the bottom surface of the block drives the block to move forward at a uniform speed along the conveying direction. Two sets of guide rollers 32 are symmetrically arranged on the left and right sides of the power roller conveyor 31, extending along the entire conveying direction. The spacing between the roller surfaces of the two guide roller sets 32 is adapted to the width of the block. When the block travels on the power roller conveyor 31, the roller surfaces of the guide rollers 322 on the left and right sides respectively abut against the left and right end faces of the block, forming a horizontal lateral constraint to prevent lateral displacement of the block during conveying and milling, ensuring the machining position accuracy of the U-shaped groove. The pressure roller set 33 is correspondingly arranged directly above the power roller conveyor 31, its roller surface pressing against the top surface of the block, forming a vertical constraint to prevent vertical jumping or end warping of the block during milling, ensuring the stability of the processing.

[0024] The tool assembly 4 is fixedly installed above the middle section of the power roller conveyor line 31 and is located in the inner area of ​​the guide channel. When the block passes through the milling station in the guide channel at a constant speed with the power roller conveyor line 31, the high-speed rotating milling tool continuously cuts the bottom surface of the block. As the block is continuously fed at a constant speed, the tool mills a complete U-shaped groove structure on the block. The block does not need to be stopped during the entire processing process, realizing the synchronous operation of conveying and processing.

[0025] During operation, the blank blocks to be processed are placed one by one on the feeding conveyor 1. The feeding conveyor 1 drives the blank blocks forward and smoothly feeds the blocks into the input end of the processing conveyor 3. After the blocks enter the power roller conveyor line 31, they continue to move forward with the rotation of the power roller 312. When the blocks enter the guide channel area, the guide roller groups 32 on the left and right sides respectively abut against the two end faces of the blocks, restricting the lateral displacement of the blocks. At the same time, the pressure roller group 33 presses against the top surface of the blocks, restricting the vertical jump of the blocks. Thus, driven by the friction of the power roller conveyor line 31, the blocks can only move forward at a constant speed along the conveying direction, maintaining a stable traveling posture throughout the process. As the block passes through the milling station where the tool assembly 4 is located at a stable speed, the high-speed rotating milling cutter cuts the bottom surface of the block. With the block being continuously and uniformly fed, the milling cutter gradually cuts a continuous U-shaped groove structure on the bottom surface of the block. Throughout the entire processing, the block maintains a uniform speed, requiring no machine stoppage for clamping or waiting. The finished block, having completed the U-shaped groove processing, continues to be conveyed forward by the power roller conveyor line 31, smoothly transitioning from the output end of the processing conveyor mechanism 3 to the finished product conveyor mechanism 2, and finally being conveyed by the finished product conveyor mechanism 2 to the stacking area, completing the entire processing flow for a single block. Subsequent blocks repeat the above process sequentially, achieving continuous production of U-shaped blocks.

[0026] In this invention, the feeding conveyor 1, the processing conveyor 3 and the finished product conveyor 2 are connected in sequence. Through the structure of the power roller conveyor line 31, the guide roller group 32 and the pressure roller group 33, the U-shaped groove milling process is completed simultaneously during the continuous and uniform speed conveying of the blocks, realizing the continuous production of U-shaped blocks, improving the overall production volume, and adapting to the large-scale production needs of U-shaped blocks.

[0027] like Figure 2 and Figure 5 As shown, a transfer platform 5 is provided at the connection position between the feeding conveyor 1 and the processing conveyor 3. The transfer platform 5 includes a lifting platform 51, a lifting drive component 52 for driving the lifting platform 51 to move in the vertical direction, and a pushing component 53 for driving the blocks on the lifting platform 51 to move toward the processing conveyor 3. A transition roller assembly 7 is also provided between the lifting platform 51 and the processing conveyor 3.

[0028] The lifting drive component 52 drives the lifting platform 51 to move vertically, making the bearing surface of the lifting platform 51 flush with the conveying surface of the feeding conveying mechanism 1. The feeding conveying mechanism 1 drives the block blank forward along its conveying direction until the block blank is completely moved onto the bearing surface of the lifting platform 51. If there is a height difference between the conveying surfaces of the feeding conveying mechanism 1 and the processing conveying mechanism 3, the lifting drive component 52 drives the lifting platform 51 to rise and fall vertically to the corresponding height, making the bearing surface of the lifting platform 51 flush with the roller surface of the transition roller assembly 7 and the conveying surface of the power roller conveying line 31, completing the height compensation adjustment before the transition. The pushing component 53 starts and pushes the side end face of the block blank in a direction parallel to the conveying direction of the processing conveying mechanism 3. Under the action of the thrust, the block blank slides out from the bearing surface of the lifting platform 51 and enters the input end of the power roller conveying line 31 after being supported by the rolling of the transition roller assembly 7. During this process, the lateral force generated by the pushing is entirely borne by the supporting structure of the lifting platform 51 and the pushing assembly 53, and will not be transmitted to the conveying components of the feeding conveying mechanism 1. In addition, a baffle is provided at the end of the lifting platform 51 corresponding to the conveying direction of the feeding conveying mechanism 1 to ensure that the blocks can be accurately moved to the support area of ​​the lifting platform 51.

[0029] In this embodiment, as Figures 2-4 As shown, the feeding and conveying mechanism 1 includes a first conveying frame 11, and a drive shaft 12 and a driven shaft 13 arranged at the beginning and end of the first conveying frame 11 along the conveying direction; both ends of the drive shaft 12 and the driven shaft 13 are provided with sprockets 14, and chains 15 are provided on the two sprockets 14 located on the same side of the drive shaft 12 and the driven shaft 13, and a plurality of conveying chain plates 16 are installed on the outer peripheral surface of the chain 15.

[0030] The system employs a parallel double-chain transmission architecture (15) with two sets of sprockets (14) in corresponding configuration. This significantly increases the support span and effective support area of ​​the chains (15) on the conveyor chain plates (16). Multiple conveyor chain plates (16) are tightly connected to form a continuous, gapless bearing surface. The bottom surface of the block is in a fully supported state throughout the entire process, effectively preventing the edges and corners of the block from getting stuck in gaps and causing damage such as bumps and chipping. It also avoids interference from conveying blockages on subsequent transition cycles, ensuring a smooth feeding process throughout. In addition, if the conveying distance is long, two sets of feeding conveyor mechanisms (1) are provided, with a transition roller assembly (7) installed between the two sets of feeding conveyor mechanisms (1).

[0031] In this invention, the lower pressure roller group 33 is correspondingly positioned above the power roller conveyor line 31 and covers the processing area of ​​the tool assembly 4; preferably, as shown in the figure... Figures 7-9 As shown, the pressure roller group 33 includes a plurality of pressure rollers 331 and at least one pressure drive assembly 332; the pressure drive assembly 332 is used to drive the plurality of pressure rollers 331 to move vertically toward or away from the power roller conveyor line 31.

[0032] Specifically, the axes of each pressing roller 331 extend horizontally and are aligned with the axis of the power roller 312. The pressing roller 331 and the power roller 312 below are arranged vertically in correspondence to form a one-to-one upper and lower clamping point.

[0033] When each set of pressing rollers 331 is equipped with an independent drive assembly, the lifting and lowering actions of each pressing roller 331 can be controlled individually. In actual production, the pressing rollers 331 at corresponding points can be sequentially controlled to descend and press down according to the block's travel position: when the front end of the block enters the processing area, the pressing roller 331 at the front end first descends to its limit, while the pressing rollers 331 at subsequent points remain raised; as the block continues to feed, each pressing roller 331 along the travel direction presses down sequentially, forming a stable vertical constraint on the portion of the block that has entered the processing area throughout the process. Simultaneously, the corresponding number of pressing rollers 331 can be flexibly activated according to the length specifications of the block to be processed, adapting to the processing needs of blocks of different lengths. Alternatively, as an optional implementation, multiple pressing rollers 331 can be simultaneously mounted on the same swing arm, driven by a set of cylinders to swing the arm, synchronously driving multiple pressing rollers 331 to perform lifting and lowering actions.

[0034] The driving component drives the pressing roller 331 to move vertically closer to the power roller conveyor line 31; when the pressing roller 331 moves downward until its roller surface presses against the top surface of the block, it forms a vertical limiting constraint on the block, preventing the block from vertically jumping or the end from lifting up during the milling process, thus ensuring the stability of the processing.

[0035] As a preferred structure of the drive assembly, the drive assembly includes a swing arm and a cylinder; the top of the swing arm is hinged to the top crossbeam of the main frame, forming a swing fulcrum; the downward pressing roller 331 is rotatably mounted on the free end of the swing arm, the tail of the cylinder body is hinged to the top crossbeam of the main frame, and the end of the piston rod of the cylinder is hinged to the middle section of the swing arm. The cylinder is arranged at an angle. When the piston rod of the cylinder extends, it pushes the swing arm to swing downward around its top hinge end, thereby driving the downward pressing roller 331 mounted on the swing arm to descend synchronously and press against the top surface of the block; when the piston rod of the cylinder retracts, it pulls the swing arm to swing upward, driving the downward pressing roller 331 to rise and lift, releasing the vertical constraint on the block.

[0036] In a preferred embodiment of the present invention, such as Figure 10 As shown, the power roller conveyor line 31 includes a second conveyor frame 311 and multiple parallel power rollers 312 arranged at equal intervals along the conveying direction; the two ends of the power rollers 312 are located between the two side beams of the second conveyor frame 311. An adjustment bracket 313 is provided between two adjacent power rollers 312. The two ends of the adjustment bracket 313 are fixed on two side beams. The two sets of guide rollers 32 adjust the distance between the two sets of guide rollers 32 by adjusting their installation positions on the adjustment bracket 313.

[0037] Specifically, the adjusting bracket 313 is set along the axis of the power roller 312, and the guide roller group 32 is locked on the adjusting bracket 313 by fastening bolts. The gap between the two power rollers 312 is greater than the diameter of the fastening bolts. During the adjustment process, the fastening bolts can slide along the strip hole 631a to adjust the position. After locking, the lateral installation position of the guide roller group 32 can be fixed, thereby changing the spacing between the left and right guide roller groups 32 to adapt to blocks of different widths.

[0038] Preferably, all the power rollers 312 rotate synchronously in the same direction by active or passive driving, forming a horizontal conveying working surface. The blocks are driven to move forward at a uniform speed along the conveying direction by the friction between the roller surface and the bottom surface of the block.

[0039] Regarding the driving method of the power rollers 312: a preferred passive driving method is that all power rollers 312 extend outward from the side beam at the same end and are fixedly fitted with transmission sprockets 14; all transmission sprockets 14 are connected by the same closed-loop transmission chain 15 to form a synchronous transmission mechanism. One of the power rollers 312 acts as the driving roller, and its shaft end is connected to the output end of the main drive motor. When the main drive motor is running, it synchronously drives all power rollers 312 to rotate in the same direction and at the same speed through the sprockets 14 and chain 15. The blocks are fed forward at a uniform speed along the conveying direction by the static friction between the roller surface and the bottom surface of the block. Another preferred active drive method is that all power rollers 312 are electric rollers with built-in motors. The roller body integrates the drive motor and reduction mechanism. Both ends of the roller are directly fixed to the side beam. Each electric roller can be independently controlled to start, stop and speed through the control system, or can be uniformly controlled to achieve synchronous operation. It directly relies on the rotation of its own roller to drive the blocks forward.

[0040] like Figures 10-13 As shown, in this invention, each guide roller group 32 includes a side support 321 and multiple guide rollers 322; the multiple guide rollers 322 are all mounted on the side support 321 via a support shaft 323; The guide roller 322 is rotatably mounted on the eccentric shaft section of the support shaft 323; the end of the support shaft 323 protruding from the eccentric shaft section is rotatably mounted on the side bracket 321. A width detection unit is provided at the feed end of the guide roller group 32, and an adjustment drive 6 is connected to the support shaft 323. The adjustment drive 6 is used to drive the support shaft 323 to rotate around its own axis.

[0041] In this scheme, based on the nominal width of the block to be processed, the overall position of the side supports 321 on both sides is first manually adjusted by adjusting the strip hole 631a of the support 313 to complete the coarse adjustment of the standard width of the guide channel. At this time, the eccentric support shaft 323 is in the initial center position, and the adjustable range of the mechanism just covers the entire positive and negative tolerance zone of the block of this specification, so there is no need to frequently adjust the support manually. Before the block enters the guide channel, the width detection unit set at the feeding end collects the actual width dimension of the current block in real time and transmits the data to the control system. The control system calculates the optimal limit gap based on the detected actual width and outputs a control signal to drive the eccentric support shafts 323 on both sides to rotate by the corresponding angle. That is, when the adjusting drive 6 drives the eccentric support shaft 323 to rotate around the main axis, the axis of the eccentric shaft segment will make a circular motion around the main axis, and its position in the horizontal direction will change linearly with the rotation angle, thereby driving the guide roller 322 mounted on it to move horizontally, which can simultaneously increase or decrease the effective limit gap between the two guide rollers 322.

[0042] Once the spacing is adjusted, the eccentric support shaft 323 locks its angle, and the guide roller 322 remains in a fixed position, providing stable lateral limiting. When the block is conveyed forward, the guide roller 322 rotates freely around the eccentric shaft section, maintaining rolling friction. After the block enters the guide channel, the limiting spacing during milling is adapted to the current block size, which can effectively suppress the block's torsional tendency and ensure the straightness and positional accuracy of the U-shaped groove.

[0043] The specific adjustment process is as follows: if the block is detected to be at its maximum positive tolerance and the actual width is greater than the marked value, the two support shafts 323 are controlled to deflect outward synchronously, driving the guide rollers 322 to move outward synchronously, thereby increasing the effective limit distance. If the block is detected to be within the minimum negative tolerance and the actual width is less than the specified value, the eccentric support shafts 323 on both sides are controlled to rotate synchronously inward, driving the guide rollers 322 to move inward synchronously, reducing the effective limit distance, eliminating excessive gaps, and ensuring that the rollers always fit the side end face of the block.

[0044] This invention achieves large-span coarse width adjustment by adjusting the strip hole 631a of the support 313 to accommodate blocks of different nominal specifications; while achieving precise micro-adjustment within a small range by using the eccentric shaft section of the support shaft 323 to accommodate dimensional tolerance fluctuations of blocks of the same specification. Only one manual coarse adjustment is required during production changeovers, and repeated manual adjustments of the support are unnecessary during production of the same specification, significantly reducing the labor intensity of operators and improving changeover and production efficiency.

[0045] More preferably, such as Figure 14The adjusting drive component 6 includes a rocker arm 61 and a connecting bolt 62; one end of the rocker arm 61 is connected to the end of the support shaft 323 extending side bracket 321, and the other end is fixedly connected to the connecting bolt 62; in the same group of guide rollers 32, at least one power source is connected to the corresponding connecting bolt 62 on multiple rocker arms 61.

[0046] In this design, the swing arm 61 is horizontally arranged, extending horizontally along its length. One end of the swing arm 61 is fixedly connected to the upper end of the support shaft 323, which can be achieved by using a key-fit set screw or interference fit, etc. There is no relative rotation between the two. When the swing arm 61 swings, it synchronously drives the support shaft 323 to rotate around its own main axis. The other end of the swing arm 61 is fixedly connected to the connecting bolt 62. The axis of the connecting bolt 62 extends vertically and is parallel to the axis of the support shaft 323. There is no relative displacement between the connecting bolt 62 and the swing arm 61. In the initial installation position, the centers of the eccentric shaft segment, the support shaft 323, and the connecting bolt 62 are collinear, and the axis of the eccentric shaft segment and the axis of the connecting bolt 62 are located on opposite sides of the axis of the support shaft 323.

[0047] Each of the connecting bolts 62 of the multiple swing rods 61 corresponds to a power source. By controlling the rotation of the support shaft 323 through an independent power source, the support shaft 323 at the front end of the guide channel can be rotated at different angles to obtain a guide channel with a gradually changing spacing from wide to narrow, which facilitates the entry of blocks.

[0048] As a preferred embodiment of the above, such as Figure 15 As shown, in the same group of guide rollers 32, the corresponding connecting bolts 62 on multiple swing rods 61 are connected to the power source through a linkage plate 63; The linkage plate 63 includes a driving surface 631 and a force-bending surface 632 that bends and extends along the side of the driving surface 631 and is connected to the power source. A strip hole 631a is provided on the driving surface 631 along the conveying direction, and multiple connecting bolts 62 are embedded in the strip hole 631a. The force-bearing surface 632 extends towards the driving surface 631 from both ends along the conveying direction to form a guide surface 633. A sliding component is provided between the guide surface 633 and the two end faces of the side bracket 321.

[0049] Specifically, the driving surface 631, the force-bearing surface 632, and the guide surface 633 cover the outer side of the side support 321; a sliding assembly is provided between the guide surface 633 and the two end faces of the side support 321. The sliding assembly can be in the form of a guide rail and roller, or a guide rail and slider; the specific structure is not limited. The power source adopts a linear drive component, such as a cylinder, electric cylinder, or lead screw module. Its cylinder body is fixedly installed on the side beam, and the end of the output rod of the power source is fixedly connected to the end face of the linkage plate 63, which is used to drive the linkage plate 63 to make horizontal linear movement perpendicular to the block conveying direction.

[0050] When the power source drives the linkage plate 63 to move, the linkage plate 63 applies a force perpendicular to the transmission direction to the connecting bolts 62 through the inner wall of the strip hole 631a, causing all the connecting bolts 62 to rotate synchronously around the support shaft 323. Since the connecting bolts 62 are fixedly connected to the swing rod 61 and the swing rod 61 is fixedly connected to the support shaft 323, this force forces the swing rod 61 to swing around the main axis of the support shaft 323, thereby causing the support shaft 323 to rotate synchronously. During the swing of the swing rod 61, the connecting bolts 62 move in an arc with the end of the swing rod 61 around the main axis of the eccentric support shaft 323. The horizontal lateral displacement component generated by this arc motion is compensated by the relative sliding of the connecting bolts 62 in the strip hole 631a of the linkage plate 63. This does not apply a lateral load to the linkage plate 63, nor does it cause motion interference or jamming, ensuring smooth and stable transmission throughout the entire process.

[0051] Once the target spacing is reached, the power source locks in its current position, and the linkage plate 63, swing rod 61, and eccentric support shaft 323 remain fixed. The limit position of the guide roller 322 remains stable, providing reliable lateral limiting for block milling and suppressing block torsional displacement caused by cutting forces. It should be noted that the power source drives multiple support shafts 323 to rotate via the linkage plate 63. The number of power sources can be selected as one or more based on the length of the linkage plate 63; the specific number is not limited.

[0052] This solution only requires a power source and a linkage plate 63 to drive all guide rollers 322 on the same side to synchronously complete the spacing adjustment. The guide surfaces 633 at both ends, together with the sliding components, form a double-point symmetrical guide constraint, which restricts the swaying and movement of the linkage plate 63, ensuring that it only makes pure linear motion in the lateral direction. At the same time, through the lateral strip hole 631a on the linkage plate 63, the arc displacement component of the swing rod 61 is adapted, eliminating the risk of motion interference between linear motion and circular motion.

[0053] like Figure 1 and Figure 6 As shown, the processing and conveying mechanism 3 is also equipped with a waste collection and treatment system; the waste collection and treatment system includes a first dust collection unit 34, a second dust collection unit 35, and a waste treatment unit 36 ​​connected to the first dust collection unit 34 and the second dust collection unit 35; the first dust collection unit 34 is connected to the top of the processing chamber, and the second dust collection unit 35 is connected to the bottom of the processing chamber.

[0054] The top of the processing bin is connected to the first dust collection unit 34, which is used to collect dust generated during the processing. The bottom of the processing bin, connected to the second dust collection unit 35, is tapered, which facilitates the centralized collection of processing waste and prevents waste from scattering everywhere. The waste treatment unit 36 ​​processes the materials collected by the first dust collection unit 34 and the second dust collection unit 35 to avoid polluting the environment.

[0055] The present invention also provides a method for conveying and forming U-shaped blocks, which employs a U-shaped block conveying and forming device and includes the following steps: The block blank is placed on the feeding conveyor 1, and the feeding conveyor 1 carries the block blank to the processing conveyor 3 for smooth transport. The block blank is transferred to the power roller conveyor line 31 of the processing and conveying mechanism 3, and the power roller conveyor line 31 drives the block blank to be fed continuously at a uniform speed. After the block enters the guide channel, two sets of guide rollers 32 abut against the two end faces of the block respectively, forming a horizontal lateral limit on the block. The lower pressure roller group 33 presses against the top surface of the block, forming a vertical limit on the block. When the block passes through the processing area of ​​the tool assembly 4 in the guide channel with a stable posture and uniform speed, the tool assembly 4 performs continuous milling processing on the block, and processes a U-shaped groove on the block. The finished blocks that have completed the U-shaped groove processing continue to be fed along the power roller conveyor line 31, smoothly transitioning from the processing conveyor mechanism 3 to the finished product conveyor mechanism 2, which then transports the finished blocks to the stacking station.

[0056] The molding method of the present invention enables continuous production of U-shaped blocks, increases the overall production volume, and meets the needs of large-scale production of U-shaped blocks.
