Description

Technical Field

[0001] The present invention relates to the technical field of cage reinforcement roll welding, and in particular to an integrated feeding and roll welding system and an integrated feeding and roll welding method. Background Art

[0002] Cage reinforcement is the main component of precast piles. The main reinforcement cage of the cage reinforcement is mainly composed of several main reinforcements arranged in a ring and spiral reinforcements welded to the outer periphery of several main reinforcements. The welding between the main reinforcement and the spiral reinforcement is completed by a roll welding machine.

[0003] The seam welder primarily consists of a traction mechanism, a rib threading mechanism, a feed tray mechanism, and an electrode mechanism. The feed tray mechanism includes a feed tray seat fixed to the base of the seam welder head, a feed tray rotatably supported on the seat, and a feed tray drive motor connected to the feed tray to drive the feed tray. Spiral ribs are wrapped around the outer circumference of the feed tray. As seam welding progresses, the spiral ribs on the feed tray are continuously consumed. When the remaining spiral ribs on the feed tray are insufficient, a new feed tray must be replaced.

[0004] At present, the mode of replacing the material tray of the seam welding machine is: two workers work together to replace the material tray. Specifically, when replacing the material tray, the seam welding machine needs to stop and wait, and two workers simultaneously remove the bolts that fix the material tray on the left and right sides of the material tray; after all the bolts are removed, the old material tray to be replaced is lifted to the material storage area using an overhead crane. One of the workers must always follow the crane and the old material tray to the material storage area and is responsible for replacing the old and new material trays on the crane; after that, the overhead crane lifts the new material tray to the installation hole of the seam welding machine, and the two workers then simultaneously tighten the bolts that fix the material tray on the left and right sides of the new material tray. Therefore, when replacing the material tray in the seam welding machine in the existing technology, the replacement time is long, which also leads to a long downtime and waiting time for the seam welding machine; in addition, the replacement space of the material tray on the seam welding machine is small, which is not conducive to workers' operation. There are problems such as high labor demand, low production efficiency, limited range of movement, and high work intensity, which ultimately leads to low daily production efficiency of the seam welding machine.

[0017] The present application also provides an integrated feeding and rolling welding method, using the integrated feeding and rolling welding system as described above, the integrated feeding and rolling welding method comprising the following steps:

[0018] A1. In the initial state, the tray replacement and buffer feeding device includes a tray mechanism located at the feeding station. The spiral ribs on the trays of the tray mechanism pass through the automatic shearing and welding device and are then wound onto the transition winding reel of the seam welder. During the seam welder seam welding operation, the tray at the feeding station rotates, and the transition winding reel rotates, feeding the spiral ribs on the trays to the transition winding reel.

[0019] A2. When the remaining spiral ribs on the material tray at the feeding station are insufficient, the material tray stops rotating and the seam welding machine stops and waits;

[0020] A3: The first clamping mechanism and the second clamping mechanism both operate and clamp the spiral reinforcement; the shears move to the section of the spiral reinforcement between the first clamping mechanism and the second clamping mechanism and cut the spiral reinforcement; the second clamping mechanism releases the spiral reinforcement;

[0021] A4: The feeding drive source in the tray mechanism at the feeding station is activated to drive the rotating support frame of the tray mechanism to move to its buffer station; the feeding drive sources in the tray mechanisms with full spiral ribs at the remaining buffer stations are activated to drive the rotating support frames of the tray mechanisms to move to the feeding stations;

[0022] A5. Pass the new spiral rib on the material tray at the feeding station to the second clamping mechanism, which clamps the new spiral rib. Move the shears to the section of the new spiral rib on the side of the second clamping mechanism facing the first clamping mechanism and cut off a section of the new spiral rib. Then, return the shears to their original position.

[0023] A6. The second clamping mechanism drives the new spiral rib to move a preset distance toward the first clamping mechanism, so that the end of the new spiral rib held by the second clamping mechanism contacts the end of the old spiral rib held by the first clamping mechanism; the welding gun moves to the contact point between the new spiral rib and the old spiral rib, and welds the end of the new spiral rib to the end of the old spiral rib;

[0024] A7. The welding gun is reset, the first clamping mechanism releases the old spiral rib, and the second clamping mechanism releases the new spiral rib;

[0025] A8: The seam welder begins seam welding. The material tray at the feeding station rotates to feed the seam welder. Simultaneously, the material tray in the material tray mechanism that moved to the buffer station in step A4 is replaced by removing the material tray from the first rotary support assembly and installing the material tray filled with spiral ribs on the first rotary support assembly.

[0026] A9. Repeat steps A2 to A8 above.

[0027] As described above, the integrated feeding and rolling welding system and method according to the present invention have the following beneficial effects:

[0028] The present application separates the material tray from the seam welding machine, arranges a rotatable transition winding tray in the seam welding machine, rotatably arranges the material tray in a material tray replacement buffer feeding device independent of the seam welding machine, and realizes the connection of the new and old spiral ribs through an automatic shearing welding device, thereby realizing the synchronous replacement of the material tray with insufficient spiral ribs during the parallel time of the seam welding work of the seam welding machine, greatly shortening the downtime waiting time of the seam welding machine when the material tray is replaced, thereby increasing the actual production time of the seam welding machine and improving the daily production efficiency of the seam welding machine.

[0185] In addition, the descriptions of "first", "second", etc. in this application are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features.

[0186] The present application provides an integrated feeding and rolling welding system for the rolling welding of cage reinforcement. For the convenience of description, the definitions of the directions in the following embodiments are as follows: the axial direction of the cage reinforcement is defined as the front-to-back direction, the horizontal radial direction of the cage reinforcement is defined as the left-right direction, and the vertical radial direction of the cage reinforcement is defined as the up-down direction. Based on this, Figure 2 In the views shown, the left and right sides of the paper are left and right directions respectively, the front and back sides of the paper are front and rear directions respectively, and the upper and lower sides of the paper are upper and lower directions respectively.

[0187] like Figure 1 and Figure 2As shown, the feeding and rolling welding integrated system involved in the present application includes a tray replacement buffer feeding device 100, an automatic shearing welding device 200, and a rolling welder 300. The tray replacement buffer feeding device 100 is used to provide spiral ribs to the rolling welder 300. The tray replacement buffer feeding device 100, the automatic shearing welding device 200 and the rolling welder 300 are arranged side by side from left to right. The spiral ribs in the tray replacement buffer feeding device 100 are conveyed to the spiral ribs from left to right. The tray replacement buffer feeding device 100, the automatic shearing welding device 200 and the rolling welder 300 are also distributed side by side along the feeding direction of the spiral ribs. The feeding direction of the spiral ribs is also the conveying direction of the spiral ribs, which is from left to right.

[0188] like Figures 3 to 5 As shown, the tray replacement cache feeding equipment 100 includes a fixed cache base 10 and at least two groups of tray mechanisms 20. The cache base 10 is provided with a feeding station 101 and cache stations corresponding to each tray mechanism 20; each group of tray mechanisms 20 includes a feeding drive source 31, a rotating support frame 40 movably mounted on the cache base 10, a first rotary support assembly 50 mounted on the rotating support frame 40, and a tray 60 detachably mounted on the first rotary support assembly 50. The feeding drive source 31 is transmission-connected to the rotating support frame 40 and drives the rotating support frame 40 to reciprocate between the feeding station 101 and the cache station. Spiral ribs are wound on the tray 60, and the tray 60 is rotatably supported on the rotating support frame 40 through the first rotary support assembly 50. The axial direction of the tray 60 is parallel to the axial direction of the cage ribs and both are in the front-to-back direction.

[0189] like Figures 9 to 12 As shown, the automatic shearing and welding equipment 200 includes a fixed connecting base 110, and a first clamping mechanism 120, a second clamping mechanism 130, a shearing mechanism 140 and a welding mechanism 150 all mounted on the connecting base 110; wherein the first clamping mechanism 120 is used to clamp the old spiral rib, and the second clamping mechanism 130 is used to clamp the old spiral rib and the new spiral rib, the old spiral rib is the spiral rib conveyed when the material tray 60 is not replaced, and the new spiral rib is the spiral rib conveyed after the material tray 60 is replaced; the second clamping mechanism 130 and the first clamping mechanism 120 clamp the old spiral rib along the spiral rib. The feeding direction of the spiral reinforcement is distributed in sequence, so the first clamping mechanism 120 is distributed on the right and the second clamping mechanism 130 is distributed on the left, and the second clamping mechanism 130 is installed on the connection base 110 so as to be movable left and right along the feeding direction of the spiral reinforcement, so that the second clamping mechanism 130 can approach or move away from the first clamping mechanism 120; the shearing mechanism 140 has a movable pliers 141, and the pliers 141 can approach or move away from the old spiral reinforcement and the new spiral reinforcement; the welding mechanism 150 has a movable welding gun 151, and the welding gun 151 can approach or move away from the contact point of the old spiral reinforcement and the new spiral reinforcement.

[0190] like Figure 27 and Figure 28 As shown, the seam welding machine 300 includes a fixed head base 220, a feed support frame 230 installed on the head base 220, and a transition winding disk 240 rotatably installed in the feed support frame 230. The transition winding disk 240 is for winding the spiral reinforcement; the axial direction of the transition winding disk 240 is parallel to the axial direction of the cage reinforcement and is in the front-to-back direction.

[0191] The present application also provides an integrated feeding and rolling welding method using the integrated feeding and rolling welding system, the integrated feeding and rolling welding method comprising the following steps:

[0192] A1. In the initial state, in the tray replacement buffer feeding device 100, only one set of tray mechanisms 20 is located at the feeding station 101 of the buffer base 10. The trays 60 in this set of tray mechanisms 20 are arranged side by side and aligned front to back with the transition winding reel 240 in the seam welder 300. The spiral ribs on the trays 60 of this set of tray mechanisms 20 pass through the automatic shearing welding device 200 and are wound around the transition winding reel 240 of the seam welder 300. The spiral ribs on the trays 60 are output to the seam welder 300. The remaining tray mechanisms 20 are located at their respective buffer stations on the buffer base 10. During the seam welder 300 seam welding operation, the trays 60 at the feeding station 101 rotate, the transition winding reel 240 rotates, and the spiral ribs on the trays 60 are fed (or discharged) to the transition winding reel 240. These spiral ribs constitute the old spiral ribs.

[0193] A2. When the remaining spiral ribs on the tray 60 at the feeding station 101 are insufficient, the tray 60 stops rotating. At the same time, the seam welder 300 stops waiting, and the transition winding drum 240 also stops rotating. That is, the conveying of the old spiral ribs stops.

[0194] A3. Both the first clamping mechanism 120 and the second clamping mechanism 130 operate and clamp the old spiral reinforcement; the pliers 141 move to the section of the old spiral reinforcement between the first clamping mechanism 120 and the second clamping mechanism 130, and the pliers 141 operate to cut the old spiral reinforcement; the second clamping mechanism 130 releases the old spiral reinforcement, and the first clamping mechanism 120 still clamps the old spiral reinforcement.

[0195] A4. The feeding drive source 31 in the tray mechanism 20 at the feeding station 101 is activated to drive the rotating support frame 40 of the tray mechanism 20 to move from the feeding station 101 to its buffer station; thereafter, the feeding drive source 31 in the tray mechanism 20 with full spiral ribs at the remaining buffer stations is activated to drive the rotating support frame 40 of the tray mechanism 20 to move from its buffer station to the feeding station 101, then the tray 60 at the feeding station 101 is a new tray 60 with sufficient spiral ribs, and the spiral ribs on the tray 60 constitute new spiral ribs.

[0196] A5. Pass the new spiral rib on the material tray 60 at the feeding station 101 to the second clamping mechanism 130. The threading operation can be performed manually. The second clamping mechanism 130 clamps the new spiral rib, and the first clamping mechanism 120 still clamps the old spiral rib. The pliers 141 move to the section of the new spiral rib on the side of the second clamping mechanism 130 facing the first clamping mechanism 120, that is, the pliers 141 move to the right side of the second clamping mechanism 130. The pliers 141 moves to cut off a section of the new spiral rib. Afterwards, the pliers 141 returns to its original position and moves away from the spiral rib.

[0197] A6. The second clamping mechanism 130 drives the new spiral rib to move a preset distance to the right in the direction close to the first clamping mechanism 120. The preset distance makes the end of the new spiral rib clamped by the second clamping mechanism 130 contact the end of the old spiral rib clamped by the first clamping mechanism 120; the welding gun 151 moves to the contact point between the new spiral rib and the old spiral rib, and welds the end of the new spiral rib to the end of the old spiral rib.

[0198] A7. The welding gun 151 is reset and away from the spiral rib; the first clamping mechanism 120 releases the old spiral rib, and the second clamping mechanism 130 releases the new spiral rib.

[0199] A8. The seam welder 300 starts the seam welding operation, the transition winding drum 240 rotates, and the material tray 60 at the feeding station 101 rotates to feed the seam welder 300, resuming the conveying of the spiral ribs. At the same time, the material tray 60 in the material tray mechanism 20 that moved to the buffer station in step A4 is replaced: the material tray 60 is detached from the first rotary support assembly 50, and then the material tray 60 full of spiral ribs is installed on the first rotary support assembly 50.

[0200] A9. Repeat steps A2 to A8 above.

[0201] In summary, the present application separates the material tray 60 from the seam welding machine 300, arranges a rotatable transition winding disk 240 in the seam welding machine 300, rotatably arranges the material tray 60 in a material tray replacement cache feeding device 100 independent of the seam welding machine 300, and arranges two or more groups of material tray mechanisms 20 in the material tray replacement cache feeding device 100, and the material trays 60 in each group of material tray mechanisms 20 are all detachable structures, and the connection of the new and old spiral ribs is achieved through the automatic shearing welding device 200 to ensure the continuous supply of spiral ribs, especially during the parallel time of the seam welding work of the seam welding machine 300, synchronously replacing the material tray 60 with insufficient spiral rib remainder, greatly shortening the downtime waiting time of the seam welding machine 300 when the material tray 60 is replaced, thereby increasing the actual production time of the seam welding machine 300 and improving the daily production efficiency of the seam welding machine 300. At the same time, the replacement of the material tray 60 is carried out on the material tray replacement buffer feeding device 100, which is not affected by the limited space of the seam welding machine 300, thereby improving the operating space of workers during the replacement of the material tray 60 and reducing the labor intensity of workers.

[0202] The following describes the preferred structures of the tray replacement buffer feeding device 100, the automatic shearing and welding device 200, and the seam welding machine 300.

[0203] Tray replacement buffer feeding equipment 100

[0204] Furthermore, if Figures 3 to 5 As shown, the movement mode of the rotating support frame 40 is as follows: the rotating support frame 40 is installed on the cache base 10 so as to be movable forward and backward along the axial direction of the material tray 60, and the feeding drive source 31 drives the rotating support frame 40 to move forward and backward, and the moving direction of the rotating support frame 40 is perpendicular to the feeding direction of the spiral rib. At the same time, the arrangement mode of the multiple groups of material tray mechanisms 20 is preferably: the group material tray mechanisms 20 are distributed side by side along the moving direction of the rotating support frame 40, and the feeding station 101 and the multiple cache stations are distributed side by side along the moving direction of the rotating support frame 40, so as to reduce the space occupied by the material tray replacement cache feeding device 100, especially the space in the left and right directions. At the same time, the feeding station 101 and the multiple cache stations on the cache base 10 are distributed side by side in the front and back directions.

[0205] Preferably, if Figure 3 and Figure 4 As shown, the material tray 60 includes a disk shaft section 61 extending axially forward and backward, and disk flanges 62 fixed to the front and rear ends of the disk shaft section 61. The spiral ribs are wound around the disk shaft section 61, and the two disk flanges 62 limit the spiral ribs forward and backward.

[0206] Furthermore, if Figure 4As shown, the feeding drive source 31 is a motor, and the material tray mechanism 20 also includes a transmission gear driven by the feeding drive source 31, a transmission rack 32 extending straight forward and backward along the moving direction of the rotating support frame 40, and a moving seat 33 fixed to the bottom of the rotating support frame 40. The transmission rack 32 is fixed to the buffer base 10 and meshes with the transmission gear. The feeding drive source 31 is installed on the moving seat 33, and the moving seat 33 is installed on the buffer base 10 so as to be movable forward and backward. When the feeding drive source 31 is running, it drives the transmission gear to rotate, and the transmission gear will move forward or backward along the transmission rack 32 while rotating, thereby driving the moving seat 33 to move forward or backward. Then, the rotating support frame 40 and the material tray 60 it carries will move forward or backward synchronously with the moving seat 33, so that the rotating support frame 40 can move back and forth between the feeding station 101 and the buffer station. Preferably, a first slide rail assembly 34 extending forward and backward is connected between the left and right sides and the middle position of the movable seat 33 and the cache base 10, so that the movable seat 33 moves forward and backward more smoothly, and multiple groups of tray mechanisms 20 share the first slide rail assembly 34.

[0207] Furthermore, if Figure 4 As shown, the material tray mechanism 20 further includes a first rotary drive source 71. The first rotary support assembly 50 includes a rotatable rotary disk 51. The first rotary drive source 71 is in transmission connection with the rotary disk 51. The material tray 60 is detachably connected to the rotary disk 51 of the first rotary support assembly 50 via at least one set of detachable connection assemblies 80 and at least one set of positioning support assemblies 90. The first rotary drive source 71 drives the rotary disk 51 of the first rotary support assembly 50 to rotate. The rotary disk 51 drives the material tray 60 to rotate synchronously via the detachable connection assembly 80 and the positioning support assembly 90, thereby enabling the material tray 60 to apply the spiral ribs. Preferably, the first rotary drive source 71 is a motor, and the transmission assembly connected between the first rotary drive source 71 and the turntable 51 includes a rotating shaft 72 rotatably supported in the rotating support frame 40, a sprocket chain mechanism 73 connected between the rear end of the rotating shaft 72 and the motor shaft of the first rotary drive source 71, and a pinion 74 fixed at the front end of the rotating shaft 72, and the pinion 74 is engaged with the tooth surface on the outer periphery of the turntable 51.

[0208] Furthermore, if Figure 3 and Figure 5 As shown, there is a set of detachable connecting components 80, which are arranged at the rear side plate flange 62 of the material tray 60 and the upper end of the rotary plate 51 of the first rotary support component 50. The preferred structure of the detachable connecting component 80 is as follows: Figure 6As shown, the detachable connecting assembly 80 includes a connecting shaft 81 installed on the front end surface of the turntable 51, a connecting baffle 82 movably mounted on the connecting shaft 81 up and down, and a locking nut 83 threadedly connected to the connecting shaft 81. The front and rear ends of the connecting baffle 82 are provided with downwardly protruding block portions 821. The front block portion 821 is clamped on the front side of the outer periphery of the rear disk flange 62 of the material tray 60, and the rear block portion 821 is clamped on the rear side of the outer periphery of the turntable 51. The locking nut 83 abuts against the upper end side of the connecting baffle 82. In this way, after tightening the locking nut 83, the locking nut 83 moves down and presses against the connecting baffle 82, thereby making the connecting baffle 82 press against the rear disk flange 62 of the material tray 60 and the turntable 51, thereby connecting the material tray 60 and the turntable 51; after loosening the locking nut 83, the locking nut 83 moves up, releasing the tight contact with the connecting baffle 82, and the connecting baffle 82 can be moved upward from the rear disk flange 62 of the material tray 60 and the turntable 51, thereby releasing the connection between the material tray 60 and the turntable 51.

[0209] Preferably, if Figure 6 As shown, the detachable connecting assembly 80 also includes a connecting seat 84 fixed to the front end of the rotating disk 51. The lower end of the connecting shaft 81, which is away from the locking nut 83, is hingedly connected to the connecting seat 84 via a pin 85 extending left and right. This allows the connecting shaft 81 to swing back and forth about the pin 85. The connecting shaft 81 also forms a swing bolt, which can fine-tune the front and rear position of the connecting block, eliminating the effects of dimensional errors and installation errors of the material tray 60 itself.

[0210] Furthermore, if Figure 3 and Figure 5 As shown, there are four groups of positioning support components 90, and the four groups of positioning support components 90 are distributed at 90-degree intervals. The preferred structure of the positioning support components 90 is as follows: Figures 6 to 8 As shown, the positioning support assembly 90 includes a hanging ear 91 fixed on the rear end surface of the rear disk flange 62 of the material tray 60, and an ear seat 92 fixed on the front end surface of the turntable 51.

The ear seat 92 is provided with a slot 921, limiting portions 922 distributed on the left and right sides of the slot 921, and a limiting groove 923 distributed on the inner side of the slot 921 along the axial direction of the hanging shaft portion 911. The hanging shaft portion 911 is clamped in the slot 921, and the limiting flange 912 is clamped in the limiting groove 923 and can abut against the limiting portion 922, so that the hanging ear 91 can only be moved upward from the ear seat 92, but cannot be separated forward.

The shearing mechanism 140 also includes a third slide rail assembly 148 extending left and right. A set of third slide rail assemblies 148 are provided between the upper and lower ends of the transverse connecting plate 144 and the shearing base 142 to improve the stability of the transverse driving source 143 when driving the transverse connecting plate 144 to move left and right.

[0222] Welding mechanism 150: Figure 12 ,as well as Figure 15 and Figure 16As shown, the welding mechanism 150 includes a welding gun 151, a welding base 152, a welding machine assembly 153, a longitudinal drive source 154, a longitudinal connecting plate 155, and a welding gun bracket 156; the welding base 152 is fixed on the rear surface of the base plate 113 in the connecting base 110, and the welding machine assembly 153 is fixed on the base frame 112 of the connecting base 110; the longitudinal drive source 154 is installed on the shearing base 142, and the longitudinal connecting plate 155 is installed on the welding base 152 so as to be movable back and forth in a direction perpendicular to the conveying direction of the spiral rib, and the longitudinal drive source 154 is transmission-connected to the longitudinal connecting plate 155 and drives the longitudinal connecting plate 155 to move back and forth; the welding gun bracket 156 is fixed on the longitudinal connecting plate 155, and the welding gun 151 is fixedly clamped in the welding gun bracket 156, and the welding gun 151 is also connected to the welding machine assembly 153. In addition, a welding opening 111 is provided on the base plate 113 of the connection base 110. The welding opening 111 passes through the welding base 152 forward and backward along the moving direction of the welding gun 151 and allows the welding gun 151 to pass through. The welding opening 111 allows the welding gun 151 to move forward to the contact point between the new spiral rib and the old spiral rib to weld the two.

[0223] Preferably, if Figure 15 and Figure 16 As shown, the longitudinal drive source 154 is a motor connected to the longitudinal connecting plate 155 via a screw-nut mechanism, driving the longitudinal connecting plate 155 to move forward and backward. The welding mechanism 150 also includes a fourth slide rail assembly 157 extending forward and backward.

[0224] Guide mechanism 160: Figure 9 and Figure 11 As shown, the automatic shearing and welding equipment 200 also includes two sets of guide mechanisms 160; along the conveying direction of the spiral rib from left to right, one set of guide mechanisms 160, a guide bracket 210, a second clamping mechanism 130, a first clamping mechanism 120, another guide bracket 210, and another set of guide mechanisms 160 are arranged in sequence from left to right.

[0225] like Figure 9 and Figure 11As shown, each set of guide mechanisms 160 includes a guide base 161, a plurality of first guide wheels 162 arranged side by side along the conveying direction of the spiral rib, a lifting guide base 163 installed on the front surface of the guide base 161, a plurality of second guide wheels 164 arranged side by side along the conveying direction of the spiral rib, and a guide drive source 165; the guide base 161 is fixed on the front surface of the base plate 113 in the connecting base 110, and the plurality of first guide wheels 162 arranged side by side along the left and right sides are rotatably installed on the guide base 161, then the second guide wheels 164 are installed side by side along the conveying direction of the spiral rib. The installation position of a guide wheel 162 is fixed; several second guide wheels 164 arranged side by side are rotatably mounted on the lifting guide seat 163. A guide drive source 165 is mounted on the front surface of the guide base 161. The guide drive source 165 is in transmission connection with the lifting guide seat 163, driving the lifting guide seat 163 up and down, so that the installation position of the several second guide wheels 164 can be changed up and down. The first guide wheel 162 and the second guide wheel 164 are arranged relative to each other in the vertical direction, and a guide channel is formed between them to allow the spiral rib to pass through. Therefore, the first guide wheel 162 can be arranged at the top and the second guide wheel 164 at the bottom, or the second guide wheel 164 can be arranged at the top and the first guide wheel 162 at the bottom. Figure 9 and Figure 11 In the illustrated embodiment, the second guide wheels 164 are positioned at the top and the first guide wheels 162 are positioned at the bottom. Thus, the first guide wheels 162 form a lower row of guide wheels, while the second guide wheels 164 form an upper row of guide wheels that can be raised and lowered. During the conveying of the spiral ribs, the second guide wheels 164 are in a lowered position, cooperating with the first guide wheels 162 to guide the conveying of the spiral ribs. During the splicing of the spiral ribs, the second guide wheels 164 are in an upward position, loosening the spiral ribs.

[0226] Preferably, the guide drive source 165 is a cylinder, and the lower end of the cylinder piston rod of the guide drive source 165 is fixedly connected to the lifting guide seat 163 through a connecting block. Figure 9 As shown, each set of guide mechanisms 160 also includes a fifth slide rail assembly 166 extending up and down. A set of fifth slide rail assemblies 166 is provided between the left and right sides of the lifting guide seat 163 and the guide base 161 to improve the stability of the guide drive source 165 when driving the lifting guide seat 163 to move up and down.

[0227] Cycloid eccentric load detection mechanism 170: Figure 9 and Figure 11As shown, the automatic shear welding device 200 further includes a cycloid eccentric load detection mechanism 170. The cycloid eccentric load detection mechanism 170 can be provided as a single group and disposed on the left side of the base plate 113 in the splicing base 110. Alternatively, the cycloid eccentric load detection mechanism 170 can be provided as two groups, one on the left side and one on the right side of the base plate 113 in the splicing base 110. The following description will take the case where the cycloid eccentric load detection mechanism 170 is provided as a single group and disposed on the left side of the base plate 113 as an example.

[0228] When the material tray 60 is in real-time discharge operation, since the spiral ribs on the material tray 60 are in a spiral retracted state, the feeding drive source 31 is required to drive the rotating support frame 40 at the feeding station 101 and the material tray 60 to move back and forth within a set range in a set direction to maintain the stability of the feeding direction; during the discharge process of the spiral ribs, the spiral ribs may be overloaded backward or forward. If the spiral ribs exceed the range in the front-to-back direction due to overload, the spiral ribs will run off the transition winding drum 240 of the seam welding machine 300. The cycloid overload detection mechanism 170 detects whether the discharge position of the spiral ribs on the material tray 60 is overloaded in the front-to-back direction, and eliminates the overload by controlling the feeding drive source 31 when overload occurs.

[0229] like Figure 17 and Figure 18As shown, the cycloid overload detection mechanism 170 includes a detection seat 171 fixed to the base plate 113 in the connection base 110, a detection slider 172 installed on the detection seat 171 so as to be movable forward and backward along the overload direction of the spiral rib, and a first limit sensor 173 and a second limit sensor 174 both installed on the detection seat 171. The moving direction of the rotating support frame 40 is parallel to the moving direction of the detection slider 172; a material through hole 1721 is provided in the detection slider 172 for allowing the spiral rib to pass through. The material passage hole 1721 is a through hole extending horizontally. The forward and backward movement direction of the detection slider 172 is perpendicular to the left-right direction of the material passage hole 1721. The material tray 60 and the detection slider 172 are arranged side by side along the direction of the material passage hole 1721. The first limit sensor 173 and the second limit sensor 174 are arranged side by side along the movement direction of the detection slider 172 and can both sense the detection slider 172. The first limit sensor 173 is located on the rear side, and the second limit sensor 174 is located on the front side. When the spiral ribs on the material tray 60 are conveyed to the transition winding reel 240 on the seam welder 300, the spiral ribs discharged from the material tray 60 will first pass through the material passage hole 1721 of the cycloid overload detection mechanism 170. Preferably, to achieve automatic control, the material discharge system also includes a control unit, and the first limit sensor 173, the second limit sensor 174, and the feed drive source 31 are all communicatively connected to the control unit. During the discharge process of the spiral rib, since the spiral rib passes through the material passing hole 1721 of the detection slider 172, the front and rear discharge positions of the spiral rib directly determine the front and rear positions of the detection slider 172. According to the feedback of the first limit sensor 173 and the second limit sensor 174, it can be judged whether the front and rear positions of the detection slider 172 are within the set range, that is, whether the front and rear discharge positions of the spiral rib are within the set range. The specific analysis is as follows.

[0230] When the discharge position of the spiral rib on the material tray 60 at the feeding station 101 is within the set range, the front and rear positions of the detection slider 172 are also within the set range. Figure 20a As shown, the detection slider 172 is in the set detection area X between the first limit sensor 173 and the second limit sensor 174. The first limit sensor 173 and the second limit sensor 174 cannot sense the detection slider 172, and neither the first limit sensor 173 nor the second limit sensor 174 outputs a detection signal.

[0231] When the material discharge position of the spiral rib on the material tray 60 at the feeding station 101 is biased backward, the detection slider 172 will move backward with the backward bias of the spiral rib. Figure 20bAs shown, at this point, the detection slider 172 has moved backward beyond the set detection area X. The first limit sensor 173 located at the rear side senses the detection slider 172, and the first limit sensor 173 outputs a detection signal. Based on the real-time feedback from the first limit sensor 173, the control unit determines that the spiral rib is biased backward. The control unit then controls the feed drive source 31, which drives the rotating support frame 40 forward, and the feed tray 60, the spiral rib, and the detection slider 172 move forward accordingly until the first limit sensor 173 no longer senses the detection slider 172 and no detection signal is output, thereby ensuring that the feeding direction of the spiral rib does not exceed the rear deviation.

[0232] When the material discharge position of the spiral rib on the material tray 60 at the feeding station 101 is biased forward, the detection slider 172 will move forward with the forward bias of the spiral rib, such as Figure 20c As shown, at this point, the detection slider 172 has moved forward beyond the set detection area X. The second limit sensor 174 located on the front side senses the detection slider 172, and the second limit sensor 174 outputs a detection signal. Based on the real-time feedback from the second limit sensor 174, the control unit determines that the spiral rib is biased forward. The control unit then activates the feed drive source 31, which drives the rotating support frame 40 backward. The feed tray 60, the spiral rib, and the detection slider 172 also move backward in response until the second limit sensor 174 no longer senses the detection slider 172 and no detection signal is output, thereby ensuring that the feeding direction of the spiral rib does not deviate from the forward direction.

[0233] Therefore, the cycloid overload detection mechanism 170 can determine whether the feeding direction of the spiral rib is overloaded forward or backward through the feedback from the first limit sensor 173 and the second limit sensor 174, and thus provide good feedback on whether the discharge position of the spiral rib in the front-to-back direction is within the set range. Furthermore, when overload occurs at the discharge position of the spiral rib, the front-to-back position of the material tray 60 at the feeding station 101 is adjusted by controlling the rotation speed of the material tray mechanism 20 at the feeding station 101, thereby adjusting the discharge position of the spiral rib. The front-to-back position of the detection slider 172 will follow the adjustment of the discharge position of the spiral rib. Combined with the feedback from the first limit sensor 173 and the second limit sensor 174, the position of the detection slider 172 is controlled within the set range, thereby precisely controlling the discharge position of the spiral rib within the set range.

[0234] Furthermore, if Figures 17 to 19As shown, the cycloid overload detection mechanism 170 also includes a connecting component 177 connected between the detection seat 171 and the detection slider 172; the connecting component 177 includes a support shaft 1771 fixed to the detection seat 171, and a first spring 1772 and a second spring 1773 both mounted on the support shaft 1771, the support shaft 1771, the first spring 1772 and the second spring 1773 all extend axially forward and backward along the moving direction of the detection slider 172, and the detection slider 172 is movably mounted on the support shaft 1771; in particular, the first spring 1772, the detection slider 172 and the second spring 1773 are distributed in sequence from back to front, the rear end and the front end of the first spring 1772 are respectively abutted against the rear side of the detection seat 171 and the detection slider 172, and the rear end and the front end of the second spring 1773 are respectively abutted against the front side of the detection slider 172 and the detection seat 171. When no spiral rib is inserted through the through-hole of detection slider 172, detection slider 172 is not affected by the spiral rib. At this point, under the action of first spring 1772 and second spring 1773, detection slider 172 is located within the set detection area X between first limit sensor 173 and second limit sensor 174. Neither first limit sensor 173 nor second limit sensor 174 senses detection slider 172. Subsequently, during the unloading process of the spiral rib, when the unloading position of the spiral rib drives the material tray 60 forward due to a backward bias, the spring force of first spring 1772 drives detection slider 172 forward. Similarly, when the unloading position of the spiral rib drives the material tray 60 backward due to a forward bias, the spring force of second spring 1773 drives detection slider 172 forward.

[0235] In addition, if Figure 17 and Figure 18 As shown, there are two sets of connecting assemblies 177. The parallel direction of the two sets of connecting assemblies 177 is orthogonal to the movement direction of the detection slider 172 and the penetration direction of the material feeding holes 1721. Therefore, the two sets of connecting assemblies 177 are arranged side by side and have the same structure. In addition, along the parallel direction of the two sets of connecting assemblies 177, the material feeding holes 1721 on the detection slider 172 are distributed between the two sets of connecting assemblies 177.

[0236] Furthermore, if Figure 17 and Figure 18As shown, the cycloid eccentric load detection mechanism 170 further includes a detection bracket 175 fixed to the detection base 171. The detection bracket 175 defines an adjustment slot 1751 extending straight forward and backward along the direction of movement of the detection slider 172. Both the first limit sensor 173 and the second limit sensor 174 are mounted in the adjustment slot 1751 of the detection bracket 175, and their respective mounting positions within the adjustment slot 1751 are adjustable. This allows the spacing between the first limit sensor 173 and the second limit sensor 174 to be adjusted, thereby adjusting the setting range of the spiral rib discharge position to meet different production requirements.

[0237] Preferably, the installation structure of the first limit sensor 173 and the second limit sensor 174 in the adjustment chute 1751 is as follows: Figure 17 and Figure 18 As shown, a locking assembly is provided between the first limit sensor 173 and the detection bracket 175, and between the second limit sensor 174 and the detection bracket 175. Both the first limit sensor 173 and the second limit sensor 174 have sensor housings. The locking assembly includes two locking nuts 83, both threadedly connected to the sensor housings. The two locking nuts 83 are arranged vertically and respectively abut against the upper and lower sides of the detection bracket 175. When the locking nuts 83 are loosened, the first and second limit sensors 173 and 174 can be moved forward and backward in the adjustment slots 1751 to adjust their front-to-back positions. After adjustment, the locking nuts 83 are tightened, and the current positions of the first and second limit sensors 173 and 174 are maintained by the two locking nuts 83 abutting against the upper and lower sides of the detection bracket 175.

[0238] Preferably, the first limit sensor 173 and the second limit sensor 174 can be of various types, including photoelectric sensors, proximity switches, travel switches, infrared sensors, Hall effect sensors, etc., and the user can select the appropriate sensor based on actual needs. When the first limit sensor 173 and the second limit sensor 174 are photoelectric sensors or infrared sensors, the detection slider 172 is made of metal. When the first limit sensor 173 and the second limit sensor 174 are Hall effect sensors, a magnet that can be sensed by the Hall effect sensors is fixed to the detection slider 172.

[0239] Furthermore, if Figure 17 and Figure 18As shown, the cycloid overload detection mechanism 170 also includes a four-way limit assembly 178 and a fixed detection guide seat 179. The detection guide seat 179 is preferably fixed directly to the detection seat 171 by screws. The preferred structure of the four-way limit assembly 178 is as follows: the four-way limit assembly 178 includes two first guide rollers 1781 distributed side by side, a first guide groove formed between the two first guide rollers 1781, two second guide rollers 1782 distributed side by side, and a second guide groove 1783 formed between the two second guide rollers 1782; the side-by-side directions of the two first guide rollers 1781, the side-by-side directions of the two second guide rollers 1782, and the through-direction of the material through-hole 1721 are orthogonal to each other. Figure 17 and Figure 18 In the illustrated embodiment, two first guide rollers 1781 are arranged side by side front to back, and two second guide rollers 1782 are arranged side by side up and down. The feed hole 1721, the first guide groove, and the second guide groove 1783 are sequentially connected from left to right along the direction of the feed hole 1721. The first guide rollers 1781 and the second guide rollers 1782 are both rotatably mounted on the detection guide seat 179. Thus, during the unwinding of the spiral rib, the four-way limit assembly 178 not only guides the movement of the spiral rib but also limits its fore-aft and up-and-down displacement.

[0240] Furthermore, among the two first guide rollers 1781, one of the first guide rollers 1781 is installed on the detection guide seat 179 so that it can be moved forward and backward along the side-by-side direction of the two first guide rollers 1781, so that the size of the first guide groove in the front-to-back direction is a range; among the two second guide rollers 1782, one of the second guide rollers 1782 is installed on the detection guide seat 179 so that it can be moved up and down along the side-by-side direction of the two second guide rollers 1782, so that the size of the second guide groove 1783 in the up and down direction is a range, thereby adapting to the setting range of the discharge position of the spiral rib.

[0241] Preferably, the installation structure of the two first guide rollers 1781 and the two second guide rollers 1782 is preferably as follows: Figure 17 and Figure 18As shown, the upper and lower ends of the first guide roller 1781 are fixed with a first rotating shaft portion 1784, and the front and rear ends of the second guide roller 1782 are fixed with a second rotating shaft portion 1785. The detection guide seat 179 is provided with a first rotating hole 1791 that rotates and cooperates with the first rotating shaft portion 1784 of the rear first guide roller 1781, a first sliding groove 1792 that rotates and slides with the first rotating shaft portion 1784 of the front first guide roller 1781, a second rotating hole 1793 that rotates and cooperates with the second rotating shaft portion 1785 of the lower second guide roller 1782, and a second sliding groove 1794 that rotates and slides with the second rotating shaft portion 1785 of the upper second guide roller 1782. The first sliding groove 1792 extends straight forward and backward along the side-by-side direction of the two first guide rollers 1781, and the second sliding groove 1794 extends straight up and down along the side-by-side direction of the two second guide rollers 1782. Therefore, the first guide roller 1781 on the rear side is only rotatably installed in the detection guide seat 179, but the first guide roller 1781 on the front side is rotatably and movably installed in the detection guide seat 179; similarly, the second guide roller 1782 on the lower side is only rotatably installed in the detection guide seat 179, but the second guide roller 1782 on the upper side is rotatably and movably installed in the detection guide seat 179; thereby adapting the setting range of the discharge position of the spiral rib.

[0242] Tensioning adjustment mechanism 180: Figure 9 and Figure 11 As shown, the automatic shearing welding equipment 200 also includes two groups of tensioning adjustment mechanisms 180, one group of tensioning adjustment mechanisms 180 is distributed on the left side of the left guide mechanism 160, and the other group of tensioning adjustment mechanisms 180 is distributed on the right side of the right guide mechanism 160, and the first clamping mechanism 120 and the second clamping mechanism 130 are distributed between the two groups of tensioning adjustment mechanisms 180; that is: along the conveying direction of the spiral rib from left to right, the cycloid overload detection mechanism 170, a group of tensioning adjustment mechanisms 180, a group of guide mechanisms 160, a guide bracket 210, the second clamping mechanism 130, the first clamping mechanism 120, another guide bracket 210, another group of guide mechanisms 160, and another group of tensioning adjustment mechanisms 180 are arranged in sequence from left to right.

[0243] like Figure 21 or Figure 24As shown, the tensioning adjustment mechanism 180 includes a mounting base 181 fixed to the front side of the base plate 113 in the connection base 110, a winding wheel 182 rotatably mounted on the mounting base 181, a winding tensioning wheel 183 movably and rotatably mounted on the mounting base 181, and a tensioning drive source 184 mounted on the mounting base 181; the outer periphery of the winding wheel 182 and the outer periphery of the winding tensioning wheel 183 are provided with a winding groove 1821, and the winding groove 1821 is a radially concave V-shaped annular groove structure, and the winding groove 1821 is used for spiral ribs to bypass; the tensioning drive source 184 is transmission-connected to the winding tensioning wheel 183, driving the winding tensioning wheel 183 to move toward or away from the winding wheel 182. Figure 21 or Figure 24 In the embodiment shown, the winding wheel 182 and the winding tensioning wheel 183 are distributed side by side in the upper and lower directions, and the winding wheel 182 is distributed on the upper side and the winding tensioning wheel 183 is distributed on the lower side, and the tensioning drive source 184 drives the winding tensioning wheel 183 to move up or down.

[0244] In the unloading system, the rotatable material tray 60 is the upstream process equipment for the tensioning adjustment mechanism 180, and the rotatable transition winding tray 240 in the seam welder 300 is the downstream process equipment for the tensioning adjustment mechanism 180. The tensioning drive source 184 is activated, driving the winding tensioning wheel 183 downward, applying a preload force to the winding tensioning wheel 183. This preload force allows the winding tensioning wheel 183 to float up and down within a certain range. The range of the floating movement is determined by the magnitude of the preload force. The spiral ribs on the feed tray 60 are wound around the winding groove 1821 of the winding wheel 182 and the winding groove 1821 of the winding tensioning wheel 183 and then wound on the transition winding disk 240 of the seam welding machine 300. The rotational speed of the feed tray 60 should match the rotational speed of the transition winding disk 240 in the seam welding machine 300. The input end speed of the spiral ribs in the tensioning adjustment mechanism 180 is directly determined by the rotational speed of the feed tray 60, and the output end speed of the spiral ribs in the tensioning adjustment mechanism 180 is directly determined by the rotational speed of the transition winding disk 240 in the seam welding machine 300.

[0245] When the speed of the spiral rib output by the front process equipment of the tensioning adjustment mechanism 180 does not match the speed of the spiral rib input into the tensioning adjustment mechanism 180 of the back process equipment: 1. When the rotation speed of the transition winding disk 240 in the back process equipment seam welding machine 300 is too fast, the output end speed of the spiral rib in the tensioning adjustment mechanism 180 is faster than the input end speed, the spiral rib in the over-tightened state will drive the winding tensioning wheel 183 to move upward in the direction close to the winding wheel 182, thereby loosening the spiral rib and preventing the spiral rib from being broken due to excessive tension; 2. When the rotation speed of the transition winding disk 240 in the back process equipment seam welding machine 300 is too slow, the output end speed of the spiral rib in the tensioning adjustment mechanism 180 is slower than the input end speed, the tensioning drive source 184 will drive the winding tensioning wheel 183 to move downward in the direction away from the winding wheel 182, thereby tightening the spiral rib and preventing the spiral rib from being detached and thrown out due to excessive looseness, thereby preventing the spiral rib from injuring people or hanging on other equipment and hanging up. Therefore, the present application can effectively prevent the spiral ribs from being broken due to being too tight or being thrown out due to being too loose during the transportation process, thereby ultimately ensuring the stable transportation of the spiral ribs.

[0246] Preferably, the tensioning drive source 184 is a tensioning cylinder, and the piston rod of the tensioning cylinder extends up and down along the parallel direction of the winding wheel 182 and the winding tensioning wheel 183. When the tensioning cylinder is used as the tensioning drive source 184, its piston rod extends downward after the tensioning cylinder is ventilated, thereby applying a pre-tightening force to the winding tensioning wheel 183. The piston rod of the tensioning cylinder can float up and down within a certain range under the action of air pressure, thereby allowing the winding tensioning wheel 183 to float up and down. Preferably, a pressure regulating valve is configured on the tensioning cylinder. The pressure regulating valve is used to adjust the air pressure of the tensioning cylinder, and then adjust the pre-tightening force applied by the tensioning cylinder to the winding tensioning wheel 183, thereby adjusting the range of the up and down floating of the winding tensioning wheel 183 to meet different production requirements.

[0247] Furthermore, if Figure 22 or Figure 25As shown, there are two winding wheels 182, which are distributed side by side in the axial direction. The winding groove 1821 on the inner winding wheel 182 is aligned with the winding groove 1821 on the winding tensioning wheel 183. When the spiral rib is wound, at the left tensioning adjustment mechanism 180: the spiral rib on the material tray 60 is wound and input from the winding groove 1821 on the inner winding wheel 182, then passes through the winding groove 1821 on the winding tensioning wheel 183, and then is wound and output from the winding groove 1821 on the outer winding wheel 182, and then passes through the left guide mechanism 160, the left guide bracket 210, the second clamping mechanism 130, the first clamping mechanism 120, the right guide bracket 210, and the right guide mechanism 160 in sequence and enters the right tensioning adjustment mechanism 180; at the right tensioning adjustment mechanism 180: the spiral rib is wound and input from the winding groove 1821 on the inner winding wheel 182, then passes through the winding groove 1821 on the winding tensioning wheel 183, and is wound and output from the winding groove 1821 on the outer winding wheel 182, and finally is wound on the transition winding disk 240 in the seam welding machine 300. Taking the left tensioning adjustment mechanism 180 as an example, the inner winding wheel 182 is the input end of the spiral rib, and the outer winding wheel 182 is the output end of the spiral rib.

[0248] Furthermore, the winding wheel 182 can be configured as an active rotation structure or a passive rotation structure, thereby enabling the tensioning adjustment mechanism 180 to have two embodiments.

[0249] Example 1 of the tensioning adjustment mechanism 180: an active tensioning adjustment mechanism 180

[0250] In the active tensioning adjustment mechanism 180, as Figures 21 to 23 As shown, the winding wheel 182 is an active winding wheel 1823; the tensioning adjustment mechanism 180 also includes a rotation driving source 1812 mounted on the mounting base 181, a driving wheel seat 1813 fixed on the mounting base 181, and a connecting shaft 1814 rotatably mounted in the driving wheel seat 1813 through a bearing 1811. The rotation driving source 1812 is connected to the connecting shaft 1814 and drives the connecting shaft 1814 to rotate. The active winding wheel 1823 is fixed on the connecting shaft 1814. During the feeding process of the spiral rib, the rotation driving source 1812 drives the connecting shaft 1814 to rotate, thereby driving the active winding wheel 1823 to rotate, driving the spiral rib to be output in the required direction, realizing active feeding, and the rotation speed of the active winding wheel 1823 matches the rotation speed of the transition winding drum 240 in the subsequent process equipment, the seam welding machine 300.

[0251] Because the active winding wheel 1823 in the active tensioning adjustment mechanism 180 has an autonomous power system, its matching speed range with the rotational speed of the transition winding disk 240 in the subsequent process equipment, the seam welder 300, is wider and more flexible, and the matching speed is more precise and controllable. When the rotational speed of the transition winding disk 240 in the subsequent process equipment, the seam welder 300, is too fast, the active winding wheel 1823 first increases the feeding speed based on the excessive rotational speed of the transition winding disk 240, and performs a secondary matching with the rotational speed of the transition winding disk 240. However, if the speeds of the two deviate too much, the speed of the spiral rib output end on the outer active winding wheel 1823 will be faster than the speed of the spiral rib input end on the inner active winding wheel 1823. The spiral rib will drive the winding tensioning wheel 183 to move upward toward the active winding wheel 1823, preventing the spiral rib from being broken due to excessive tension. When the rotation speed of the transition winding disk 240 in the subsequent process equipment, the seam welding machine 300, is too slow, the active winding wheel 1823 first reduces the feeding speed according to the excessive rotation speed of the transition winding disk 240, and performs secondary matching with the rotation speed of the transition winding disk 240. However, when the speed deviation between the two is too large, the speed of the output end of the spiral rib on the outer active winding wheel 1823 is slower than the speed of the input end of the spiral rib on the inner active winding wheel 1823. The tensioning cylinder drives the winding tensioning wheel 183 to move downward away from the active winding wheel 1823 to prevent the spiral rib from being detached and thrown out due to being too loose.

[0252] Preferably, if Figures 21 to 23 As shown, the rotation driving source 1812 is a servo motor, which is fixedly connected to the rear end of the connecting shaft 1814 through a reducer, and the reducer is fixed on the mounting base 181.

[0253] Example 2 of the tensioning adjustment mechanism 180: a driven tensioning adjustment mechanism 180

[0254] In the driven tension adjustment mechanism 180, Figures 24 to 26As shown, the winding wheel 182 is a driven winding wheel 1822. The tensioning adjustment mechanism 180 also includes a driven wheel seat 189 fixed to the mounting base 181. The driven wheel seat 189 has an integral support shaft section 1810 extending straight forward. The driven winding wheel 1822 is rotatably mounted on the support shaft section 1810 via a bearing 1811. During the feeding process of the spiral rib, the driven winding wheel 1822 rotates with the spiral rib, and the spiral rib is output in the desired direction. When the rotation speed of the transition winding drum 240 in the subsequent process equipment, the seam welder 300, is too fast, the speed of the spiral rib output end of the outer driven winding wheel 1822 is faster than the speed of the spiral rib input end of the inner driven winding wheel 1822. The spiral rib will drive the winding tensioning wheel 183 to move upward toward the driven winding wheel 1822, preventing the spiral rib from being broken due to overtightening. When the rotation speed of the transition winding disk 240 in the subsequent process equipment seam welding machine 300 is too slow, the speed of the spiral rib output end on the outer driven winding wheel 1822 is slower than the speed of the spiral rib input end on the inner driven winding wheel 1822. The tensioning cylinder drives the winding tensioning wheel 183 to move downward away from the driven winding wheel 1822 to prevent the spiral rib from being detached and thrown out due to being too loose.

[0255] In this embodiment, in the two sets of tensioning adjustment mechanisms 180, the winding wheel 182 in the left tensioning adjustment mechanism 180 close to the material tray replacement buffer feeding device 100 is the active winding wheel 1823, and the winding wheel 182 in the right tensioning adjustment mechanism 180 close to the seam welding machine 300 is the driven winding wheel 1822.

[0256] Furthermore, in the two embodiments of the tensioning adjustment mechanism 180, the preferred connection structure between the tensioning cylinder and the winding tensioning wheel 183 is as follows: Figures 21 to 23 As shown, or as Figures 24 to 26 As shown, the tensioning adjustment mechanism 180 further includes a movable plate 185. A tensioning drive source 184 is connected to the movable plate 185 to drive the movable plate 185 to move up and down. The movable plate 185 is mounted on the mounting base 181 so as to be movable up and down. The winding tensioning wheel 183 is rotatably mounted on the movable plate 185. Preferably, the tensioning adjustment mechanism 180 further includes a fifth slide rail assembly 166 extending straight up and down along the moving direction of the winding tensioning wheel 183. The movable plate 185 is connected to the mounting base 181 via the fifth slide rail assembly 166, thereby improving the smoothness of the upward and downward movement of the movable plate 185.

[0257] Furthermore, if Figures 21 to 23 As shown, or as Figures 24 to 26As shown, along the axial direction of the winding tensioning wheel 183, the winding tensioning wheel 183, the movable plate 185 and the tensioning drive source 184 are distributed in sequence from front to back; the movable plate 185 includes a plate main body 1851, and a plate connecting portion 1852 integrally extending downward from the plate main body 1851 along the moving direction of the winding tensioning wheel 183, and a connecting rod 186 extending forward and backward along the axial direction of the winding tensioning wheel 183 is rotatably connected to the plate connecting portion 1852, and the connecting rod 186 is connected to the output end of the tensioning drive source 184 through a fisheye joint 187. During the feeding process of the spiral rib, the load force applied by the spiral rib to the winding tensioning wheel 183 has an offset load. The connecting rod 186 and the fisheye joint 187 can eliminate the influence of the offset load force on the piston rod of the tensioning cylinder, thereby extending the service life of the tensioning cylinder.

[0258] Seam welding machine 300

[0259] The structure of the transition winding drum 240 is substantially the same as that of the material drum 60; Figure 27 and Figure 28 As shown, the transition winding drum 240 also includes a drum shaft section 61 extending axially forward and backward, and drum flanges 62 fixed to the front and rear ends of the drum shaft section 61. The spiral ribs are wound around the drum shaft section 61, and the two drum flanges 62 limit the front and rear positions of the spiral ribs. The feed support frame 230 in the seam welding machine 300 is a fixed structure, fixed to the head base 220 of the seam welding machine 300.

[0260] like Figure 27 and Figure 28 As shown, the seam welding machine 300 also includes a second rotary support assembly 250 mounted on the feed support frame 230, and a second rotary drive source 260 mounted on the head base 220. The second rotary support assembly 250 has a rotatable rotary disk 51. The second rotary drive source 260 is connected to the rotary disk 51 of the second rotary support assembly 250 and drives the rotary disk 51 to rotate. The rotary disk 51 of the second rotary support assembly 250 is also detachably connected to the transition winding disk 240 through at least one set of detachable connection components 80 and at least one set of positioning support components 90. In this way, the transition winding disk 240 in the seam welding machine 300 is a detachable structure, which facilitates the maintenance and replacement of the transition winding disk 240. Preferably, the second rotary drive source 260 is a motor, and the transmission component connected between the second rotary drive source 260 and the rotary disk 51 of the second rotary support assembly 250 has the same structure as the transmission component connected between the first rotary drive source 71 and the rotary disk 51 of the first rotary support assembly 50, and also includes a rotating shaft 72, a sprocket chain mechanism 73 and a pinion 74, which will not be repeated here.

[0261] like Figure 29As shown, the detachable connecting assembly 80 and the positioning support assembly 90 connected between the turntable 51 of the second rotary support assembly 250 and the transition winding reel 240 have the same structure as the detachable connecting assembly 80 and the positioning support assembly 90 connected between the turntable 51 and the material tray 60 of the first rotary support assembly 50, so the detachable connecting assembly 80 connected between the turntable 51 of the second rotary support assembly 250 and the transition winding reel 240 also includes a connecting shaft 81, a connecting baffle 82, a locking nut 83 and a connecting seat 84, and the positioning support assembly 90 connected between the turntable 51 of the second rotary support assembly 250 and the transition winding reel 240 also includes a matching hanging ear 91 and an ear seat 92, which will not be repeated here.

[0262] Furthermore, the following Figure 1 、 Figure 3 and Figure 4 Taking the embodiment of the tray replacement buffer feeding equipment 100 shown in the figure as an example, which has two tray mechanisms 20, the working process of the feeding and rolling welding integrated system with the above structure is described.

[0263] 1. In the initial state, if Figure 1 and Figure 3 As shown, in the two tray mechanisms 20 of the tray replacement and buffer feeding device 100, the trays 60 in both tray mechanisms 20 are full. The front tray mechanism 20 is located at the feeding station 101, and the buffer stations of the front tray mechanism 20 are distributed in front of the feeding station 101. The buffer stations of the front tray mechanism 20 are defined as first buffer stations 102. The rear tray mechanism 20 is located at its buffer station, and the buffer stations of the rear tray mechanism 20 are defined as second buffer stations 103. The second buffer stations 103 are distributed behind the feeding station 101.

[0264] 2. The material tray 60 in the front material tray mechanism 20 and the transition winding disk 240 in the seam welding machine 300 both rotate, and the rotation speeds of the two are matched. The spiral rib is supplied to the seam welding machine 300 by the material tray 60 in the front material tray mechanism 20. The spiral rib passes through the cycloid eccentric load detection mechanism 170, the left tensioning adjustment mechanism 180, the left guide mechanism 160, the left guide bracket 210, the second clamping mechanism 130, the first clamping mechanism 120, the right guide bracket 210, the right guide mechanism 160, and the right tensioning adjustment mechanism 180 in the automatic shearing welding equipment 200, and then the spiral rib is wound on the transition winding disk 240 of the seam welding machine 300. During the feeding process of the spiral rib, in the automatic shearing welding equipment 200: the several second guide wheels 164 of the two sets of guide mechanisms 160 are in the lowering position, playing a guiding role; the pair of first clamping jaws 122 in the first clamping mechanism 120, and the pair of second clamping jaws 132 in the second clamping mechanism 130 are both in the open state, and do not clamp the spiral rib; the pliers 141 are distributed between the first clamping jaw 122 and the second clamping jaw 132, but are located on the upper side of the spiral rib, which position is also the standby position of the pliers 141; the welding gun 151 is distributed on the rear side of the base plate 113, which position is also the standby position of the welding gun 151.

[0265] 3. When the spiral ribs on the material tray 60 in the front material tray mechanism 20 are used up, the front material tray mechanism 20 is empty and the feeding is completed; the seam welding machine 300 stops and waits, the material tray 60 of the front material tray mechanism 20 stops rotating, and stops conveying the spiral ribs, which constitute old spiral ribs.

[0266] IV. Operation of the automatic shearing and welding equipment 200: The pair of first clamping jaws 122 in the first clamping mechanism 120 and the pair of second clamping jaws 132 in the second clamping mechanism 130 are both closed, and both the first clamping mechanism 120 and the second clamping mechanism 130 clamp the old spiral rebar. The lifting drive source 145 in the shearing mechanism 140 drives the shears 141 downward to the old spiral rebar. The shears 141 close and shear the old spiral rebar; then, the shears 141 return to their standby position. The guide drive source 165 of the left guide mechanism 160 drives the lifting guide seat 163 upward, which in turn drives the plurality of second guide wheels 164 upward, releasing the old spiral rebar in their guide channels. Next, the second clamping mechanism 130 releases the old spiral rebar, and the old spiral rebar on the left side of the shears 141 is manually gathered onto the material tray 60 of the front material tray mechanism 20.

[0267] 5. The feeding drive source 31 in the front material tray mechanism 20 is activated to drive the front material tray mechanism 20 to move forward to the first buffer station 102 .

[0268] 6. The feeding drive source 31 in the rear material tray mechanism 20 is activated, driving the rear material tray mechanism 20 to move forward to the feeding station 101 .

[0269] VII. Automatic Cutting and Welding Equipment 200 Connects the Spiral Rebar on the Reel 60 in the Rear Feed Tray Mechanism 20 with the Old Spiral Rebar in the Seam Welding Machine 300: The new spiral rebar on the reel 60 in the rear feed tray mechanism 20 is manually threaded to a suitable position, ensuring that it reaches at least the second clamping mechanism 130. The guide drive source 165 in the left guide mechanism 160 drives the lifting guide seat 163 downward, driving the plurality of second guide wheels 164 downward to retain the new spiral rebar in its guide channel; and the second clamping mechanism 130 clamps the new spiral rebar. The transverse driving source 143 and the lifting driving source 145 in the shearing mechanism 140 are both activated, driving the shearing pliers 141 to move downward and transversely to the left to the set position and to the right side of the second clamping mechanism 130; then, the shearing pliers 141 closes and cuts off a section of the new spiral reinforcement; this step is to trim the joint end of the new spiral reinforcement, so that the welding joint of the new spiral reinforcement and the welding joint of the old spiral reinforcement can be more easily welded together, which is convenient for subsequent welding; after the reinforcement cutting is completed, the shearing pliers 141 returns to its standby position, ready for the subsequent welding station. The second clamping mechanism 130 moves the new spiral rebar to the right by a preset distance, toward the first clamping mechanism 120. This preset distance causes the end of the new spiral rebar held by the second clamping mechanism 130 to contact the end of the old spiral rebar held by the first clamping mechanism 120, thereby driving the weld joint of the new spiral rebar to the right, toward the welding station. The weld joint of the new spiral rebar remains in the welding station. The longitudinal drive source 154 in the welding mechanism 150 drives the welding gun 151 forward to the welding station. The welding gun 151 is activated to weld the weld joint of the new spiral rebar to the weld joint of the old spiral rebar. The welding gun 151 moves backward and returns to its standby position. Simultaneously, the pair of first clamping jaws 122 in the first clamping mechanism 120 and the pair of second clamping jaws 132 in the second clamping mechanism 130 open, releasing the old spiral rebar from the first clamping mechanism 120 and the new spiral rebar from the second clamping mechanism 130. At this point, the connection between the new and old spiral rebars is complete.

[0270] 8. The material tray 60 in the rear material tray mechanism 20 at the feeding station 101 rotates, the supply and delivery of the spiral ribs is resumed, and the seam welding machine 300 starts the seam welding operation; at the same time, the front material tray mechanism 20 replaces its material tray 60 at the first buffer station 102, so that the material tray 60 in the front material tray mechanism 20 is full.

[0271] 9. When the spiral ribs on the material tray 60 in the rear material tray mechanism 20 are used up, the rear material tray mechanism 20 is empty and the feeding is completed, the seam welding machine 300 stops and waits, the material tray 60 of the rear material tray mechanism 20 stops rotating, and the spiral ribs are stopped from being conveyed. The spiral ribs constitute old spiral ribs.

[0272] 10. Repeat step 4 above to cut off the old spiral ribs, and manually gather the old spiral ribs on the left side of the shears 141 onto the material tray 60 of the rear material tray mechanism 20 .

[0273] 11. The feeding drive source 31 in the rear material tray mechanism 20 is activated, driving the rear material tray mechanism 20 to move backward to the second buffer station 103.

[0274] 12. The feeding drive source 31 in the front material tray mechanism 20 is activated, driving the front material tray mechanism 20 to move backward to the feeding station 101.

[0275] 13. Repeat step 7 above to complete the connection of the new and old spiral reinforcements.

[0276] 14. The material tray 60 in the front material tray mechanism 20 at the feeding station 101 rotates, the supply and delivery of the spiral ribs is resumed, and the seam welding machine 300 starts the seam welding operation; at the same time, the rear material tray mechanism 20 replaces its material tray 60 at the second buffer station 103, so that the material tray 60 in the rear material tray mechanism 20 is full.

[0277] 15. Return to step 3 above and repeat this cycle.

[0278] In summary, this application has the following advantages:

[0279] 1. When the material tray replacement buffer feeding device 100 feeds the spiral ribs to the seam welder 300, the worker can simultaneously replace the material tray by replacing another empty material tray 60 on the cache feeding device 100, thereby achieving a one-for-one function, and being able to continuously feed the seam welder 300, reducing the downtime waiting time of the seam welder 300 for each material tray replacement 60 by at least 50%, increasing the actual production seam welding time of the seam welder 300, and improving the daily production efficiency of the seam welder 300.

[0280] 2. The replacement of the tray 60 is carried out at the cache station of the tray replacement cache feeding device 100, which is not affected by the narrow head area of ​​the seam welding machine 300. This solves the problem of small operating space and poor working environment when replacing the empty tray 60, and also reduces the labor intensity and employment cost of workers. The entire process of replacing the tray 60 can be completed by only one worker.

[0281] 3. Automatic cutting The welding device 200 has an automatic cutting function. When the material tray 60 needs to be replaced, it can automatically cut the old spiral reinforcement at the appropriate position.

[0282] 4. The automatic shearing welding device 200 has a welding connection function. After the material tray 60 is replaced, the new spiral rib on the new material tray 60 is welded to the old spiral rib on the transition winding reel 240 of the seam welder 300, thereby realizing continuous feeding of the spiral rib and achieving the purpose of quickly resuming seam welding, which is conducive to shortening the downtime waiting time of the seam welder 300.

[0283] 5. The automatic shearing welding device 200 has a spiral rib tensioning adjustment function. Through the active tensioning adjustment mechanism 180 and the passive tensioning adjustment mechanism 180, the spiral rib is prevented from being pulled apart too tightly or being hung up too loosely when rotating and feeding during the rolling welding process.

[0284] 6. The automatic shearing welding equipment 200 is equipped with a cycloid overload detection mechanism 170, which can provide real-time feedback on the overload degree of the spiral rib discharge position and correct the spiral rib discharge position in real time to achieve controllable feeding direction and prevent the transition winding reel 240 from running out.

[0285] 7. This application is applicable to various specifications of cage reinforcement, such as the outer diameter outer diameter outer diameter outer diameter outer diameter and outer diameter The outer diameter of the precast pile reinforcement outer diameter outer diameter outer diameter outer diameter and outer diameter The specifications of the spiral reinforcement corresponding to the cage reinforcement of the precast pile are and
