In this way, the worm 13 cooperates with each turbine 14, and the worm 13 rotates to drive each fixed needle 12 to rotate. In this way, the self-rotation of the material tube can make the cutting process smooth, reduce burrs and splashes generated during the cutting process, and improve the cutting quality; it can effectively prevent the surface of the material tube from being scratched or damaged; it can reduce the wear of the cutting tool, and at the same time make the cutting process smooth and improve the cutting efficiency.

[0029] The second fixed seat assembly 60 includes an auxiliary support seat 62, on which a plurality of auxiliary support columns 61 are arranged along the same direction.

[0035] The tube cutting assembly 50 includes a cutter 5125. The cutter 5125 can move and has a seventh switching position and an eighth switching position. The cutter 5125 is arranged close to the second fixed seat assembly 60, and the cutter 5125 cuts the material tube to form a tube bead; when the cutter 5125 is in the eighth switching position, the cutter 5125 is arranged away from the second fixed seat assembly 60, and the cutter 5125 is located above the second fixed seat assembly 60.

[0036] like Fig.10 As shown, the pipe cutting assembly 50 includes a cutter portion 51 and a first swinging portion 52, and the cutter portion 51 includes a support member 5121 and a cutter mounting member 5122. The first swinging portion 52 is connected to the support member 5121, and the first swinging portion 52 swings to drive the support member 5121 to swing, and the cutter mounting member 5122 is connected to the support member 5121, and the cutter mounting member 5122 is provided with a cutter mounting groove 51221, and the cutter 5125 is mounted in the cutter mounting groove 51221 through a rotating shaft, and the cutter 5125 can rotate around the rotating shaft. When the cutter 5125 is in the seventh switching position, the support member 5121 can reciprocate in the vertical direction to drive the cutter 5125 to reciprocate in the vertical direction.

[0037] The cutter portion 51 is described in detail below: like Fig.13 and Fig.14 As shown, the cutter portion 51 includes a support beam 511, a cutter structure 512, a first telescopic mechanism 513, a second telescopic mechanism 514 and a second linear guide mechanism 515. The cutter structure 512 is movably connected to the support beam 511 through the second linear guide mechanism 515. When the cutter 5125 is in the seventh switching position, the cutter structure 512 can reciprocate in the vertical direction, thereby driving the cutter 5125 of the cutter structure 512 to reciprocate in the vertical direction. Among them, the movable end of the second telescopic mechanism 514 is connected to the cutter structure 512, and the second telescopic mechanism 514 can be a hydraulic or cylinder mechanism, a linear motor mechanism, a screw and nut mechanism, etc., which is not limited in this embodiment.

[0038] like Fig.15As shown, the cutter structure 512 includes a support member 5121, a cutter mounting member 5122, a second air pipe 5123, a pressing member 5124 and a cutter 5125. The support member 5121 can be but is not limited to a plate shape, and the movable end of the second telescopic mechanism 514 is connected to the support member 5121.

[0039] like Fig.16 As shown, the cutter mounting member 5122 is provided with a cutter mounting groove 51221 extending in the front-rear direction, and the cutter 5125 is mounted in the cutter mounting groove 51221 via a rotating shaft. The cutter 5125 is arc-shaped or circular, and the cutter 5125 can rotate around the rotating shaft when in contact with the material pipe. Among them, the cutter 5125 corresponds to the auxiliary support column 61 mentioned above, and the cutter mounting member 5122 is threadedly connected to the support member 5121 via a fastener, and the cutter mounting member 5122 is arranged at the lower end of the support member 5121.

[0040] like Fig.15 and Fig.16 As shown, the second air pipe 5123 is connected to the support member 5121, and the second air pipe 5123 is arranged at the lower end of the support member 5121, so that the second air pipe 5123 can swing with the cutter 5125. A second air hole is opened on the second air pipe 5123, and when the cutter 5125 is in the seventh switching position, the second air hole faces the cutter 5125. When the cutter 5125 cuts the material pipe and generates dust particles, the gas based on the second air hole is continuously blown to the cutter 5125, thereby preventing the dust particles from falling into the above-mentioned second groove, which helps to prevent the dust particles from affecting the material pipe when a new material pipe is placed in the second groove later.

[0041] like Fig.15 and Fig.16 As shown, the pressing member 5124 may be, but is not limited to, plate-shaped, and may be made of an elastic material, such as a rubber material, a silicone material, a plastic material, and the like. An installation cavity 51211 is provided inside the support member 5121, and the pressing member 5124 is located in the installation cavity 51211, and is arranged near the lower end of the support member 5121. The first telescopic mechanism 513 is at least partially located in the installation cavity 51211, and the movable end of the first telescopic mechanism 513 is connected to the pressing member 5124. In this way, on the one hand, the pressing member 5124 swings with the cutter 5125, and when the cutter 5125 is in the seventh switching position, the pressing member 5124 can elastically press the material tube; on the other hand, when the cutter 5125 is in the seventh switching position, the pressing member 5124 can reciprocate in the vertical direction relative to the support member 5121 through the first telescopic mechanism 513, so as to further adjust the elastic force of the pressing member 5124 on the material tube.

[0042] In addition, at least Fig. 22 and Fig.23As shown, the bead tube processing device also includes a first support seat 82. The first fixed seat 11, the first support seat 82, the second fixed seat 66, and the auxiliary support seat 62 are arranged in sequence from left to right. The first support seat 82 supports the middle part of the material tube.

[0043] The first support seat 82 can reciprocate in the vertical direction, so that when the first direction driving mechanism causes the first fixing seat 11 to reciprocate in the left-right direction, interference between the first support seat 82 and the first fixing seat 11 can be avoided.

[0044] At least in conjunction with the accompanying drawings Figure 1-Figure 24 , describe the working steps of the bead tube processing device: S111, each fixed needle 12 on the first fixed seat 11 is provided with a material tube, such as Figure 4 As shown, the left end of the material tube is plugged into the fixed needle 12. Fig.19 As shown, the right end of the material tube is arranged in the second groove of the second fixing seat 66, and at the same time, the support groove 611 of each auxiliary support column 61 supports a material tube. At the current moment, each cutter 5125 is in the eighth switching position, such as Fig.11 As shown, such a configuration helps to prevent the material tube from accidentally colliding with the support beam 511 of the cutter portion 51 when the material tube is placed in the second groove; S112, the worm 13 cooperates with each turbine 14, and the worm 13 rotates, so that each turbine 14 rotates, thereby causing each fixed needle 12 to rotate, so that each material tube rotates; S113, the first direction driving mechanism drives the first fixing seat assembly 10 to move rightward by a first preset distance, and the first fixing seat 11 approaches the second fixing seat 66, wherein the first preset distance controls the length of the first bead tube; S114, under the action of the first swinging part 52, the cutter 5125 switches from the eighth switching position to the seventh switching position. Based on the action of the first linear guide mechanism 64, the auxiliary support seat 62 moves upward in the vertical direction, driving the auxiliary support column 61 to move upward, so that the auxiliary support column 61 applies an upward force to the material tube. At the same time, based on the action of the second linear guide mechanism 515, the cutter structure 512 moves downward in the vertical direction, driving the pressing member 5124 and the cutter 5125 to move downward, the pressing member 5124 presses the material tube, and the cutter 5125 applies a downward force to the material tube. Fig.19As shown, the cutter 5125 and the auxiliary support column 61 are arranged vertically opposite to each other, and the material tube is sandwiched between them. During the cutting process, the force applied by the cutter 5125 and the auxiliary support column 61 to the material tube can prevent the material tube from vibrating or shifting, so that the material tube remains stable, which helps to make the position of the cut of the material tube flat, thereby ensuring the accuracy of the size of the first bead tube; because the auxiliary support column 61 elastically supports the material tube, the auxiliary support column 61 can prevent the material tube from vibrating or shifting on the one hand, and on the other hand, avoid affecting the self-rotation of the material tube. The setting of the pressing member 5124 further improves the stability of the material tube, and because the pressing member 5124 is made of elastic material, it does not affect the self-rotation of the material tube.

[0045] S115. When the cutter 5125 cuts the material tube, the second air hole faces the cutter 5125, so that dust particles generated by cutting are kept away from the second groove of the second fixing seat 66, thereby preventing the dust particles from falling into the second groove.

[0046] S116, after acquiring the first bead tube, the support beam 511 still maintains the position corresponding to step S114. Based on the action of the first linear guide mechanism 64, the auxiliary support seat 62 moves downward in the vertical direction, driving the auxiliary support column 61 to move downward, and the auxiliary support column 61 returns to the initial position and breaks contact with the material tube; based on the action of the second linear guide mechanism 515, the cutter structure 512 moves upward in the vertical direction, driving the pressing member 5124 and the cutter 5125 to move upward, and the pressing member 5124 and the cutter 5125 return to the initial position and break contact with the material tube; in addition, the second air hole stops blowing air to the cutter 5125; S117, the first direction driving mechanism causes the first fixing seat assembly 10 to continue to move rightward by a second preset distance, and the first fixing seat 11 continues to approach the second fixing seat 66. The second preset distance controls the length of the second bead tube, and the length of the second bead tube may be equal to the length of the first bead tube, or may be different from the length of the first bead tube; S118, repeat S114, S115, S116 until the Nth bead tube, N is a positive integer, and the entire material tube is cut; S119, the cutter 5125 of the cutter part 51 is switched from the seventh switching position to the eighth switching position under the action of the first swinging part 52. In the current position, the support beam 511 and the cutter 5125 are arranged away from the second fixing seat 66; S120, each fixing needle 12 on the first fixing seat 11 is reset to another material tube, refer to the description of S111, so it will not be repeated.

[0047] It should be noted that the embodiment of the present application does not limit the order of execution of the above steps S111, S112, S113, S114, S115, and S116. In some embodiments, the cutter 5125 elastically cuts the material tube, and the second fixed seat assembly 60 non-elasticly supports the material tube; or, in other embodiments, the cutter 5125 elastically cuts the material tube, and the second fixed seat assembly 60 elastically supports the material tube.

[0048] In this way, during the cutting process, the material tube is elastically cut by the cutter 5125, and / or the auxiliary support column 61 elastically supports the material tube. The force applied by the cutter 5125 and the auxiliary support column 61 to the material tube can prevent the material tube from vibrating or shifting, so that the material tube remains stable, and helps to flatten the position of the cut of the material tube, thereby ensuring the accuracy of the bead tube size. Since the auxiliary support column 61 elastically supports the material tube and the cutter 5125 elastically cuts the material tube, the auxiliary support column 61 or the cutter 5125 can avoid the material tube from vibrating or shifting on the one hand, and avoid affecting the rotation of the material tube on the other hand. The setting of the pressure piece 5124 further improves the stability of the material tube, and since the pressure piece 5124 is made of elastic material, it does not affect the rotation of the material tube.

[0049] In the above step S118, each fixing needle 12 on the first fixing seat 11 will have a cut material head left, and the material head on the fixing needle 12 needs to be manually removed so that the bead tube processing device can load a new material tube. However, due to the large number of fixing needles 12, the process of manually removing the material head is cumbersome and wastes a lot of time, thereby affecting the working efficiency of the bead tube processing device.

[0050] Based on this, the bead tube processing device of the present application further includes a material head extraction mechanism 30. A fixed needle 12 is provided on the first fixed seat 11, and the fixed needle 12 is used to plug the end of the material tube. The fixed needle 12 cooperates with the material head extraction mechanism 30 to allow the material head located on the fixed needle 12 to be detached from the fixed needle 12. In this way, the material heads on each fixed needle 12 can be automatically removed, avoiding manual removal of the material heads, reducing the labor intensity of the operator, shortening the time for collecting the material heads, and improving the processing efficiency of the bead tube.

[0051] In detail, the first fixed seat 11 can rotate and have a first switching position and a second switching position. When the first fixed seat 11 is in the first switching position, the length of the fixed needle 12 is set along the first direction; when the first fixed seat 11 is in the second switching position, the length of the fixed needle 12 is set along the vertical direction or tilted, and the fixed needle 12 cooperates with the material head pulling mechanism 30 to make the material head on the fixed needle 12 detach from the fixed needle 12.

[0052] Among them, Figure 4As shown, the first fixed seat 11 is fixedly connected to the rotating plate, and the rotating plate drives the rotating shaft plate to rotate through the relevant mechanism, so that the first fixed seat 11 switches between the first switching position and the second switching position. When the first fixed seat 11 is in the first switching position, the length of the fixed needle 12 is set in the left-right direction; when the second fixed seat 11 is in the second switching position, the length of the fixed needle 12 is set in the vertical direction. The relevant mechanism can be a belt mechanism, a sprocket mechanism, a gear mechanism, etc., which is not limited in this embodiment.

[0053] like Figure 8 , Fig. 22 and Fig.23 As shown, a material pulling head mechanism 30 is installed on the first mounting portion 73, and the material pulling head mechanism 30 is located below the first fixed seat 11. The material pulling head mechanism 30 includes a first friction roller 31 and a second friction roller 32, and the axis of the first friction roller 31 is parallel to the axis of the second friction roller 32, and the axes of the two extend in the front-to-back direction.

[0054] At least one of the first friction roller 31 and the second friction roller 32 rotates, and the side surfaces of the first friction roller 31 and the second friction roller 32 are frictionally matched with the material heads on the fixed needle 12. The material heads on each fixed needle 12 can be clamped between the first friction roller 31 and the second friction roller 32 to apply a downward force to the material heads so that the material heads are separated from the fixed needle 12. If both the first friction roller 31 and the second friction roller 32 rotate, their rotation directions are opposite.

[0055] Furthermore, a friction layer is provided on the outer side of the first friction roller 31 and the second friction roller 32, and the friction layer includes a spiral pattern. Since the surface of the material tube is smooth, it is not conducive to the two friction rollers to clamp it. The spiral pattern can significantly increase the friction between the friction roller and the material tube, and can improve the friction roller's force in picking up and squeezing the material tube.

[0056] Further, the first friction roller 31 and the second friction roller 32 reciprocate synchronously in a second direction, and the second direction is perpendicular to the first direction.

[0057] like Figure 8 , Fig. 22 and Fig.23 As shown, the second direction is the front-to-back direction. The first friction roller 31 and the second friction roller 32 synchronously swing back and forth in the front-to-back direction. In this way, the contact surface between the material head and the fixed needle 12 can be continuously changed, thereby reducing the friction between the material head and the fixed needle 12; the force direction and angle of the material head can be changed, making the extraction action more flexible.

[0058] Furthermore, the distance between the axis of the first friction roller 31 and the axis of the second friction roller 32 is adjustable. In this way, the material pulling head mechanism 30 can be adapted to material heads of different diameters.

[0059] Furthermore, the first friction roller 31 and the second friction roller 32 can reciprocate in the vertical direction. In this way, the first friction roller 31 and the second friction roller 32 can adjust their heights according to the length of the slug to ensure that the first friction roller 31 and the second friction roller 32 can clamp slugs of different lengths.

[0060] It should be noted that between steps S118 and S119 , or between steps S119 and S120 , the material head removal mechanism 30 is performed to remove the material head.

[0061] In the above step S111, the material tube needs to be manually plugged into the fixing needle 12. However, due to the large number of fixing needles 12, the process of manually plugging the material tube is cumbersome and wastes a lot of time, thereby affecting the working efficiency of the bead tube processing device.

[0062] Based on this, the bead tube processing device of the present application further includes a second support seat 81 and an auxiliary component 20. The second support seat 81 is used to support the end of the material tube. The second support seat 81 and the first fixing seat 11 are spaced apart in the first direction, such as Figure 1 As shown, the first fixing seat 11, the second supporting seat 81, and the first supporting seat 82 are arranged in sequence from left to right. The auxiliary component 20 cooperates with one end of the material tube to make the material tube approach the fixing needle 12 until the material tube is sleeved on the fixing needle 12. In this way, each fixing needle 12 can be automatically plugged with a material tube, avoiding manual plugging of the material tube, reducing the labor intensity of the operator, shortening the time of plugging the material tube, and improving the processing efficiency of the bead tube.

[0063] Among them, Figure 2 and Figure 3 and Figure 7 and Figure 8 As shown, the auxiliary component 20 includes a third friction roller 21, and the third friction roller 21 can move and has a third switching position and a fourth switching position. The third friction roller 21 is in the third switching position, the third friction roller 21 is arranged close to the second support seat 81, the third friction roller 21 rotates, and the side surface of the third friction roller 21 frictionally cooperates with one end of the material tube so that the material tube is inserted into the fixed needle 12; the third friction roller 21 is in the fourth switching position, the third friction roller 21 is arranged away from the second support seat 81, and the third friction roller 21 is disengaged from one end of the material tube.

[0064] In detail, Figure 22-Figure 24 As shown, the second support seat 81 has a plurality of third grooves arranged in the front-to-back direction, and the third grooves are adapted to the material tubes, which helps to stabilize the position of the material tubes, so that each material tube is correspondingly arranged with a fixing needle 12 .

[0065] like Figure 2 and Figure 3As shown, the auxiliary assembly 20 includes a third friction roller 21, a second swinging portion 22, an auxiliary support seat 24 and a synchronous belt assembly 25. The second swinging portion 22 is connected to the auxiliary support seat 24, and at the same time, the first fixed seat 11 is also connected to the auxiliary support seat 24. In the first direction driving mechanism, the nut is connected to the auxiliary support seat 24. The screw rod rotates, and the nut drives the first fixed seat 11 and the auxiliary support seat 24 to reciprocate in the left and right directions.

[0066] The second swinging portion 22 enables the third friction roller 21 to switch between the third switching position and the fourth switching position. Figure 8 As shown, when the third friction roller 21 is in the third switching position, the third friction roller 21 is located directly above the second support seat 81, and the left end of the material tube is clamped between the third friction roller 21 and the second support seat 81. Under the action of the third friction roller 21, the material tube moves to the left, and the material tube approaches the fixed needle 12 until the material tube is inserted into the fixed needle 12. After the material tube is inserted into the fixed needle 12, the third friction roller 21 switches from the third switching position to the fourth switching position. At this moment, Figure 7 or Figure 8 As shown, the third friction roller 21 is arranged away from the second support seat 81 , and the third friction roller 21 is located above the first fixed seat 11 or the second support seat 81 .

[0067] The synchronous belt assembly 25 includes a driving pulley 251 and a driven pulley 252. The driving pulley 251 is mounted on the output shaft of the driving motor, the driving motor is mounted on the second swinging part 22, and the driven pulley 252 is coaxially arranged with the third friction roller 21, and the driven pulley 252 drives the third friction roller 21 to rotate.

[0068] Considering the material and strength of the material tube, the material tube is prevented from being squeezed and deformed during the plugging process. Therefore, the motion trajectory of the third friction roller 21 is selected to be arc-shaped. The arc trajectory is smoother than the straight trajectory, and can effectively reduce the impact and vibration during the movement. At the same time, the arc trajectory can achieve high-precision motion control.

[0069] Furthermore, when the third friction roller 21 is in the fourth switching position, the third friction roller 21, the first fixed seat 11 and the second support seat 81 are orthographically projected on the same horizontal plane, there is an overlapping area between the projection of the third friction roller 21 and the projection of the first fixed seat 11, and there is a gap between the projection of the third friction roller 21 and the projection of the second support seat 81. In this way, in the above step S111 or S120, when placing the material tube, accidental collision between the material tube and the third friction roller 21 can be avoided.

[0070] Furthermore, the second support seat 81 can reciprocate in the vertical direction. In this way, when the first direction driving mechanism causes the first fixing seat 11 to reciprocate in the left and right directions, the second support seat 81 can be prevented from interfering with the first fixing seat 11. When the third friction roller 21 is in the third switching position, the axis of the third groove and the axis of the fixing needle 12 of the first fixing seat 11 are located on the same straight line.

[0071] Furthermore, a rubber layer or a silicone layer is provided on the outer side of the third friction roller 21. The rubber layer or the silicone layer can increase the friction between the third friction roller 21 and the material tube, and can further enable the material tube to be inserted into the fixing needle.

[0072] In actual applications, when the material tube is inserted into the fixing needle 12, there is a problem that the material tube is not firmly inserted, which affects the subsequent cutting.

[0073] Based on this, Figure 3 As shown, the bead tube processing device of the present application also includes a material box assembly 40, and the material box assembly 40 includes a material box 42, and a bonding material is provided in the material box 42. The material box 42 cooperates with the fixing needle 12 so that the fixing needle 12 contacts the bonding material. In this way, before the material tube is plugged into the fixing needle 12, a bonding material is provided on the fixing needle 12, and the bonding material can improve the strength of the material tube connected to the fixing needle 12, avoid the problem of loose plugging of the material tube, and thus help the subsequent cutting process, such as ensuring the stability of the material tube, helping the material tube cut position to be flat, and ensuring the accuracy of the bead tube size.

[0074] The material box 42 moves in the first direction to have a fifth switching position and a sixth switching position. When the material box 42 is in the fifth switching position, the material box 42 is located below the first fixing seat 11; when the material box 42 is in the sixth switching position, the material box 42 is located away from the first fixing seat 11.

[0075] like Fig. 22 and Fig.23 As shown, the material box assembly 40 includes a material box cover 41 and a material box 42 located in the material box cover 41. The material box cover 41 is fixedly connected to the first mounting portion 73, and the material box 42 moves in the left and right directions to have a fifth switching position and a sixth switching position. Figure 5As shown, when the material box 42 is in the sixth switching position, the material box 42 is located in the material box cover 41; when the material box 42 is in the fifth switching position, the material box 42 moves from the material box cover 41 to the bottom of the fixing seat 11. At this moment, the first fixing seat 11 switches from the first switching position to the second switching position, the fixing needle 12 cooperates with the material box 42, and the end of the fixing needle 12 is bonded to the adhesive in the material box 42. Then, the first fixing seat 11 switches from the second switching position to the first switching position, and then the fixing needle 12 is plugged into the material tube. In this way, each fixing needle 12 is provided with adhesive, and based on the joint action of the third friction roller 21 and the second support seat 81, the material tube is stably plugged into the fixing needle 12.

[0076] It should be noted that if Figure 8 As shown, when the material box 42 moves in the left-right direction, since the first friction roller 31 and the second friction roller 32 can reciprocate in the vertical direction, the interference problem between the material box 42 and the first friction roller 31 and the second friction roller 32 can be avoided.

[0077] In addition, the material box assembly 40 also includes a scraper assembly 43, which includes a scraper member 431 and a connecting shaft 432 connected to the scraper member 431. The connecting shaft 432 is connected to the material box 42 so that the scraper member 431 is located in the material box 42, wherein the axis of the connecting shaft 432 extends in the front-to-back direction.

[0078] like Figure 5 and Figure 6 As shown, the scraper 431 includes a scraper end surface 4311 and a material leakage hole 4312 arranged near the scraper end surface 4311. The length direction of the scraper 431 is parallel to the axis direction of the connecting shaft 432. The connecting shaft 432 is rotatably connected to the material box 42, and the connecting shaft 432 can be driven by a motor, a hydraulic drive, a pneumatic drive, etc. to rotate the connecting shaft 432, and the connecting shaft 432 drives the scraper 431 to rotate.

[0079] In this way, during the movement of the material box 42, the scraper end surface 4311 scrapes and levels the solid-liquid phase change material end surface in the material box 42, avoiding the unevenness of the solid-liquid phase change material end surface and affecting the adhesion of the solid-liquid phase change material to the end of the fixed needle 12; during the scraping and leveling process, the solid-liquid phase change material passes through the leakage hole 4312. The setting of the leakage hole 4312 can reduce the contact area between the scraper 431 and the solid-liquid phase change material, making the scraping and leveling more labor-saving, controlling the scraping and leveling force, and improving the flatness; it helps to discharge excess solid-liquid phase change material and avoid accumulation that affects the scraping and leveling effect. As the solid-liquid phase change material is consumed, it decreases. When the scraper 431 cannot scrape the solid-liquid phase change material end surface, the distance between the scraper end surface 4311 and the solid-liquid phase change material end surface is reduced by rotating the connecting shaft 432.

[0080] Furthermore, a heating component 83 is included. The heating component 83 conducts heat transfer with the fixing needle 12 of the first fixing seat 11 in the first switching position.

[0081] Among them, Figure 8 As shown, the heating component 83 is connected to the second support base 81. The heating component 83 is located between the second support base 81 and the first fixing base 11. The solid-liquid phase change material is heated and the viscosity decreases.

[0082] like Figure 8 , Fig. 22 and Fig.23 As shown, the heating assembly 83 includes a first air pipe, which is fixedly connected to the second support seat 81, and is located directly below the fixing pin 12 of the first fixing seat 11 in the first switching position. The first air pipe is provided with a plurality of first air holes arranged in the front-to-back direction, and each first air hole corresponds to a fixing pin 12. Gas is provided in the first air pipe, and the first air holes discharge the gas, and the gas burns and heats the fixing pin 12. The fixing pin 12 with a higher temperature melts the solid-liquid phase change material so that the end of the fixing pin 12 is fully provided with the solid-liquid phase change material, which can further ensure the stability of the material pipe plugging the fixing pin 12.

[0083] In addition, if Figure 8 As shown, the second support seat 81 is also connected to a glue plate 84, and the glue plate 84 is located below the first air pipe. This can prevent the solid-liquid phase change material accidentally dropped from the fixing needle 12 from affecting other mechanisms, such as the first friction roller 31 and the second friction roller 32.

[0084] Considering that there is a risk of damaging the third friction roller 21 during the process of the first gas pipe discharging the gas to heat the fixed needle 12, the auxiliary component 20 further includes a first baffle plate 23, which is connected to the second swinging portion 22 through a related connecting member, so that the first baffle plate 23 moves with the third friction roller 21.

[0085] like Figure 8 As shown, when the third friction roller 21 is in the third switching position, the first shielding plate 23 is located between the first air hole and the third friction roller 21, and is arranged close to the side of the third friction roller 21. In this way, the first shielding plate 23 can shield the influence of the flame on the third friction roller 21, thereby ensuring the integrity of the third friction roller 21.

[0086] Before step S111 is performed, the end of the fixed needle 12 is bonded to the solid-liquid phase change material, and the process may include the following steps: S211, the first air hole of the first air pipe discharges gas, and the combustion of the gas heats the fixing needle 12 of the first fixing seat 11 in the first switching position; S212, the second support seat 81 moves downward in the vertical direction to prevent the first air pipe from interfering with the moving fixed needle 12; at the same time, the first friction roller 31 and the second friction roller 32 move downward in the vertical direction to prevent the material box 42 from interfering with the first friction roller 31 and the second friction roller 32; S213, the material box 42 moves rightward from the material box cover 41 until the material box 42 moves to the fifth switching position, that is, the material box 42 moves to below the first fixed seat 11; S214, the first fixing seat 11 switches from the first switching position to the second switching position, the fixing needle 12 moves downward from the horizontal position, the fixing needle 12 cooperates with the material box 42, and the end of the fixing needle 12 is bonded to the adhesive in the material box 42; S215, the first fixing seat 11 switches from the second switching position to the first switching position, the fixing needle 12 returns to the horizontal position, and then the step S111 is executed.

[0087] It should be noted that, considering that in the process of removing the material head under the action of the first friction roller 31 and the second friction roller 32, the material head is affected by the adhesive. Therefore, between steps S118 and S119, or between steps S119 and S120, in the process of removing the material head by the material head removal mechanism 30, before the material head is removed, the first gas pipe discharges gas again to heat the fixed needle 12 with the material head, and the adhesive is heated and the viscosity is reduced, so that it is convenient for the first friction roller 31 and the second friction roller 32 to remove the material head.

[0088] At least Fig. 9 , Fig. 22 and Fig.23 As shown, the bead tube processing device also includes a receiving hopper 90 , which is installed close to the second mounting portion 74 , and the receiving hopper 90 is correspondingly arranged with the connecting seat 65 so that the bead tubes can be completely recovered through the receiving hopper 90 .
