[0034] Two columns 41 are symmetrically installed at the top of the base 1 at one side of the concave frame 31. A moving block 43 is movably connected up and down inside the column 41. A squeezing roller 44 is rotatably connected between the two moving blocks 43.

[0035] A placement rack 51 is fixedly installed at the top of the base 1 at one side of the column 41, a cylinder 52 is fixedly installed at the top of the placement rack 51, and the output end of the cylinder 52 passes through the placement rack 51, and a cutter 53 is fixedly installed at the output end of the cylinder 52;

[0036] A stress relief assembly 6 is installed inside the water tank 26, and the stress relief assembly 6 includes a water pump 61 fixedly installed inside the water tank 26, a connecting pipe 62 is clamped and installed at the water outlet of the water pump 61, a fixing ring 63 is fixedly installed at one end of the connecting pipe 62, a spray pipe 64 is equidistantly embedded and installed at one end of the fixing ring 63, a mounting pipe 65 is fixedly installed inside the connecting pipe 62, an airbag sheet 66 is equidistantly embedded and installed on the outside of the mounting pipe 65, a connecting pipe 67 is embedded and installed on the top of the mounting pipe 65, a guide cover 68 is fixedly installed at one end of the connecting pipe 67, an extrusion column 69 is movably connected inside the guide cover 68, a connecting strip 610 is fixedly installed at one end of the extrusion column 69, and the connecting strip 610 is fixedly installed on the top of the limiting plate 32.

[0037] like Figure 1 and Figure 2 As shown, a driving motor 23 is installed on one side of the mounting frame 21 by screws, and the output shaft of the driving motor 23 and the driving roller 22 are fixed by a flat key, and a movable block 24 is connected to the inside of the mounting frame 21 by screws, and a pressing roller 25 is rotatably connected between the two movable blocks 24. Two conical covers 27 are fixedly installed at one end surface of the mounting frame 21 at equal distances;

[0038] It is used to guide the cylindrical tin column so that the tin column enters the same position between the laminating roller 25 and the driving roller 22, thereby facilitating subsequent guiding, and changing the distance between the laminating roller 25 and the driving roller 22, thereby adjusting the thickness of the tin bar after lamination.

[0039] like Figure 1 and Figure 2 As shown, the top of the limit plate 32 is connected with a bolt 33 through a thread, and the bolt 33 is slidably connected to the inside of the concave frame 31, and one end surface of the concave frame 31 is provided with placement grooves 34 at equal intervals;

[0040] The position of the limiting plate 32 can be adjusted easily, and the adjusted limiting plate 32 can be squeezed and fixed, thereby reducing the difficulty of squeezing and fixing the limiting plate 32 .

[0041] like Figure 1 and Figure 2 As shown, a knife holder 55 is installed inside the placement rack 51 at the bottom of the cutter 53, and a fitting groove for fitting the cutter 53 is opened inside the knife holder 55. A positioning sensor 54 is installed at the top edge of the inner wall of the placement rack 51;

[0042] It is convenient to limit the cutter 53, changes the difficulty of limiting the cutter 53, and facilitates the cutting of the tin bar. At the same time, the positioning sensor 54 is used to measure the position of the tin block after cutting, and further facilitates the transfer structure to transfer the tin block. At this time, the equipment stops and waits for the placement machine to suck the material. When the placement machine sucks away a tin block, the positioning sensor 54 loses its sensitivity, and the device drives the next tin block to enter the bottom of the positioning sensor 54, and uses them in sequence to realize the transfer of the tin block.

[0043] like Figure 3 and Figure 4 As shown, a horizontal column 611 is embedded and installed at one end of the fixed ring 63 away from the driving roller 22, a collar 612 is fixedly installed at one end of the horizontal column 611, and an air jet 613 is equidistantly embedded and installed at one end surface of the collar 612 close to the fixed ring 63, a horizontal tube 614 is embedded and installed between the two collars 612, and a fan 615 is fixedly installed at the top of the horizontal tube 614;

[0044] When the fan 615 is running, it drives the external gas into the air jet pipe 613. At this time, the gas ejected from the air jet pipe 613 cleans the water stains on the outside of the tin bar, so that the tin bar remains clean after the stress is eliminated.

[0045] like Figure 3 and Figure 4 As shown, the fixing ring 63 and the sleeve ring 612 are provided with chambers inside, the fixing ring 63 and the sleeve ring 612 are both welded with support rods at the bottom ends thereof, and the bottom ends of the support rods are fixedly connected to the bottom ends of the inner walls of the water tank 26;

[0046] It is used to connect the fixing ring 63 and the sleeve ring 612, and can support the fixing ring 63 and the sleeve ring 612, so as to limit the positions of the fixing ring 63 and the sleeve ring 612 and prevent the positions of the fixing ring 63 and the sleeve ring 612 from being offset.

[0047] like Figure 3 and Figure 4 As shown, four support columns 616 are fixedly installed on the top of the fan 615, and the top of the support column 616 is fixedly connected to the top of the inner wall of the water tank 26;

[0048] It is used to adjust the distance between the fan 615 and the water tank 26, so that the fan 615 can have an air inlet channel, thereby facilitating the normal operation of the fan 615.

[0049] like Figure 5 and Figure 6As shown, a positioning assembly 7 is movably installed inside the limiting plate 32, and the positioning assembly 7 includes a slider 71 movably connected to the inside of the limiting plate 32, a moving bar 72 is fixedly installed on the top of the slider 71, and rotating disks 73 are rotatably connected on both sides of the moving bar 72. A screw rod 74 is embedded and installed at one end of the rotating disk 73, and the outer side of the screw rod 74 is connected to a limiting block 75 through a threaded connection;

[0050] The stability of the limiting plate 32 can be increased, displacement of the limiting plate 32 can be prevented, and the positioning accuracy of the tin bar can be further increased.

[0051] like Figure 5 and Figure 6 As shown, the movable bar 72 is movably connected with a movable plate 76 inside, the movable plate 76 is connected with a bearing 77 inside by interference fit, the bearing 77 is connected with a rhombus column 78 inside by interference fit, and the screw rod 74 and the rotating disk 73 are provided with a rhombus hole at one end corresponding to the rhombus column 78;

[0052] It can facilitate the synchronous rotation of the two rotating disks 73 and enable the two rotating disks 73 to rotate independently, thereby facilitating the adjustment of the position of the limit block 75 and changing the difficulty of adjusting the position of the limit block 75.

[0053] Working principle: During the actual use of the device, the personnel put the tin column roll onto the mounting frame 21, and then introduce the tin column along the conical cover 27 to the top of the driving roller 22 and the bottom of the pressing roller 25. At this time, the position of the movable block 24 is adjusted to adjust the position of the pressing roller 25, thereby adjusting the distance between the pressing roller 25 and the driving roller 22, and further making the thickness of the pressed tin bar meet the set range;

[0054] Then, the pressed tin bar is inserted into the fixing ring 63 and the sleeve ring 612 along the water tank 26. At this time, the water pump 61 is connected to the power supply and starts to run. When the water pump 61 is running, water is pumped into the fixing ring 63 along the connecting pipe 62, and into the spray pipe 64 along the fixing ring 63, and then sprayed on the outside of the tin bar along the spray pipe 64, so that the tin bar is impacted and vibrated by the flow rate of water, and the tin bar is quickly cooled by water. The physical and mechanical properties of the tin bar are improved by rapid cooling and stress relief treatment, so as to facilitate the welding between the tin bar and the material, and the rapid heat transfer ability of water helps to evenly cool the entire tin bar, avoiding the concentration of thermal stress caused by local overheating or overcooling, thereby maintaining the consistency of the product and reducing product defects;

[0055] Then the stress-released tin bar enters the inside of the collar 612, and the fan 615 is connected to the power supply and starts to run. When the fan 615 is running, the gas is driven to spray on the surface of the tin bar along the jet pipe 613, and the surface of the tin bar is treated by the gas, thereby keeping the surface of the tin bar dry and preventing the problem of liquid remaining on the surface of the tin bar and affecting the subsequent processing of the tin bar.

[0056] Then, the limiting plate 32 is pulled, and the limiting plate 32 moves along the inside of the concave frame 31, so that the limiting plate 32 enters the edge of the tin bar, and then the tin bar is positioned, and then the bolt 33 is turned, and the tin bar is initially fixed after the bolt 33 is turned, and then the personnel moves the slider 71, and the slider 71 drives the moving bar 72 to enter the placement groove 34, and then the personnel rotates the rotating disk 73, and the rotating disk 73 drives another rotating disk 73 to rotate under the action of the diamond column 78, so that the two screw rods 74 rotate synchronously, so that the limiting block 75 moves inside the placement groove 34, so that the limiting block 75 The movable plate 76 is pulled to move the rhombus column 78 through the bearing 77, so that one end of the rhombus column 78 is separated from one rotating disk 73, and the other end is inside the other rotating disk 73, so that the two rotating disks 73 can rotate separately. This method can make the limit plate 32 more stably fixed, prevent the limit plate 32 from being displaced, further improve the stability of the tin bar during transportation, and facilitate the subsequent cutting of the tin bar, thereby improving the cutting accuracy of the tin bar.

[0057] At the same time, since the movement of the limit plate 32 drives the connection strip 610 to move, the movement of the connection strip 610 drives the extrusion column 69 to move, and the movement of the extrusion column 69 drives the liquid inside the guide cover 68 to flow, the liquid flows along the connecting pipe 67 into the inside of the mounting tube 65, and squeezes the airbag sheet 66 along the mounting tube 65, so that the airbag sheet 66 expands, and the expanded airbag sheet 66 changes the flow speed of the liquid inside the connecting tube 62, so that the impact force of the liquid on it can be adjusted according to the tin bars of different widths, so as to ensure that the impact force of the water flow can be adjusted according to the size and thickness of the tin bar, so as to achieve uniform water flow distribution, ensure that each part of the tin bar can be evenly cooled, thereby improving the stress elimination effect of the tin bar;

[0058] Then the personnel adjust the moving block 43 through the screw 42. At this time, the moving block 43 moves and drives the squeezing roller 44 to move. After the squeezing roller 44 moves, the tin bar is pressed. Then the tin bar enters the placement rack 51 and is at the top of the knife rack 55. Then the cylinder 52 is started. The cylinder 52 drives the cutter 53 to cut the tin bar, so that the tin bar becomes a tin block. At the same time, the positioning sensor 54 is used to measure the position of the tin block after cutting. Then the transfer structure is used to transfer the tin block. At this time, the equipment stops and waits for the placement machine to suck the material. After the placement machine sucks away a tin block, the positioning sensor 54 loses its induction. In the setting, the next tin block is driven to enter the bottom of the positioning sensor 54, and they are used in sequence to realize the transfer of the tin blocks.

[0059] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
