[0018] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] As described in the background technology, before the cord fabric of one of the unwinding stations is about to run out, the tail of the cord fabric from the unwinding station is joined with the head of the cord fabric from another unwinding station by means of a conventional cord fabric calendering joint device, so as to ensure the continuity and stability of the calendering process and improve production efficiency. However, the joining effect of the tail of the cord fabric and the head of the cord fabric by means of the conventional cord fabric calendering joint device is not good, which affects the subsequent production process.

[0020] To solve the above problems, refer to Figure 1The present invention provides a fiber cord calendering joint device, comprising a first unwinding mechanism 110, a second unwinding mechanism 120, a film 230 releasing mechanism 130 and a vulcanizing mechanism 140. The first unwinding mechanism 110 is used to release the tail 210 of a roll of cord that is about to be used. The second unwinding mechanism 120 is used to release the head 220 of another roll of cord that is about to be used. The film 230 releasing mechanism 130 is used to release the film 230 between the tail 210 and the head 220. The vulcanizing mechanism 140 is used to press the tail 210, the head 220 and the film 230, and heat the tail 210, the head 220 and the film 230 to join the tail 210 and the head 220. On the whole, the tail 210 and the head 220 can be joined instead of manual labor or assisted by manual labor, thereby ensuring the continuity and stability of the calendering process and improving the production efficiency. Compared with the traditional cord calendering joint device, the joint effect is improved, the possibility of misalignment and disconnection of the joint between the material head 220 and the material tail 210 is reduced, the impact on the subsequent production process is avoided, and the handling performance and quality of the finished tire are guaranteed.

[0021] Specifically, in the exemplary embodiment, the vulcanization mechanism 140 includes a fixed pressing seat 141 and a movable pressing seat 142. The fixed pressing seat 141 can generate heat. The movable pressing seat 142 is arranged opposite to the fixed pressing seat 141 and can move toward or away from the fixed pressing seat 141. The movable seat can also generate heat. When the material tail 210 and the material head 220 are pressed between the fixed pressing seat 141 and the movable pressing seat 142, and the film 230 is pressed between the material tail 210 and the material head 220, the movable pressing seat 142 moves toward the fixed pressing seat 141, and then the material tail 210, the material head 220 and the film 230 are heated with the help of the movable pressing seat 142 and the fixed pressing seat 141, so that the material tail 210 and the material head 220 are joined.

[0022] Specifically, in the example, Figure 2 , Figure 3 and Figure 4As shown, the fixed pressing seat 141 is provided with a first air extraction hole 1411 on the side facing the movable pressing seat 142, and a first air extraction cavity 1412 connected to the first air extraction hole 1411 is formed inside, and a first air extraction port 1413 connected to the first air extraction cavity 1412 is provided on the side away from the movable pressing seat 142. The first air extraction port 1413 is suitable for communicating with a negative pressure generator, so that the first air extraction hole 1411 generates negative pressure, thereby making the material head 220 fit on the side surface of the fixed pressing seat 141 facing the movable pressing seat 142. The movable pressing seat 142 is provided with a second air extraction hole 1421 on the side facing the fixed pressing seat 141, and a second air extraction cavity 1422 connected to the second air extraction hole 1421 is formed inside, and a second air extraction port 1423 connected to the second air extraction cavity 1422 is provided on the side away from the fixed pressing seat 141. The second air extraction port 1423 is also suitable for communicating with the negative pressure generator so that the second air extraction hole 1421 generates negative pressure, thereby making the material head 220 fit on the side surface of the fixed pressing seat 141 facing the movable pressing seat 142. Before the material tail 210 is joined with the material head 220, the material head 220 is first fixed by means of the fixed pressing seat 141, and the material tail 210 is fixed by means of the movable pressing seat 142 to prevent the positions of the material head 220 and the material tail 210 from shifting, thereby ensuring the joining effect. The vulcanization mechanism 140 also includes a first heating element 143 and a second heating element 144. The first heating element 143 is installed in the first air extraction cavity 1412, and is used to heat the side of the fixed pressing seat 141 facing the movable pressing seat 142, so as to heat the material tail 210, the material head 220 and the film 230, so as to cause a vulcanization reaction, so that the material tail 210 and the material head 220 are joined. A first air extraction hole 1411 is also formed on the first heating element 143. The second heating element 144 is installed in the second air extraction cavity 1422, and is used to heat the side of the movable pressing seat 142 facing the fixed pressing seat 141, so as to heat the material tail 210, the material head 220 and the film 230, so as to cause a vulcanization reaction and make the material tail 210 and the material head 220 bonded.

[0023] Preferably, a guide column 1414 is respectively provided at the four corners of the fixed pressing seat 141 on the side facing the movable pressing seat 142. A guide hole for the guide column 1414 to pass through is respectively provided at the four corners of the movable pressing seat 142. When the movable pressing seat 142 moves toward the fixed pressing seat 141, the guide column 1414 plays a guiding role, thereby ensuring the bonding effect.

[0024] Preferably, the vulcanizing mechanism 140 further comprises a first driving cylinder. The piston rod of the first driving cylinder is fixedly connected to the movable pressing seat 142, and can drive the movable pressing seat 142 to move toward or away from the fixed pressing seat 141, so as to improve the degree of automation.

[0025] Preferably, the vulcanization mechanism 140 further includes a frame, on which the first driving cylinder, the fixed pressing seat 141 and the movable pressing seat 142 are mounted, and the frame supports the first driving cylinder, the fixed pressing seat 141 and the movable pressing seat 142 .

[0026] Preferably, there are multiple first air extraction holes 1411, which are distributed in multiple rows and columns, and each first air extraction hole 1411 is connected to the first air extraction cavity 1412 to ensure the adsorption effect on the material head 220. There are multiple second air extraction holes 1421, which are distributed in multiple rows and columns, and each second air extraction hole 1421 is connected to the first air extraction cavity 1412 to ensure the adsorption effect on the material tail 210.

[0027] Preferably, the first air pumping cavity 1412 is a conical structure to ensure the air pumping effect. The second air pumping cavity 1422 is a conical structure to ensure the air pumping effect.

[0028] Preferably, the negative pressure generator may be an air pump or a vacuum pump or the like.

[0029] Preferably, the first heating element 143 is plate-shaped and has a large contact area with the fixed pressing seat 141, ensuring that the various parts of the fixed pressing seat 141 facing the movable pressing seat 142 are heated uniformly, thereby improving the bonding effect. The second heating element 144 is plate-shaped and has a large contact area with the movable pressing seat 142, ensuring that the various parts of the movable pressing seat 142 facing the fixed pressing seat 141 are heated uniformly, thereby improving the bonding effect.

[0030] Preferably, the first heating element 143 and the second heating element 144 may be electric heaters or magnetic excitation heaters or the like.

[0031] Specifically, in the example, Figure 1 and Figure 2As shown, the first unwinding mechanism 110 includes a first unwinding roller 111, a third driving motor (not shown in the figure), two first reversing rollers 112, a first driving motor 113 and a third reversing roller 114. The first unwinding roller 111 can rotate around its own axis to release the material tail 210. The output shaft of the third driving motor is fixedly connected to one end of the first unwinding roller 111 to drive the first unwinding roller 111 to rotate, thereby improving the degree of automation. The two first reversing rollers 112 are arranged in parallel above the movable pressing seat 142 to change the traveling direction of the material tail 210. A material tail 210 channel for the material tail 210 to pass through is formed between the side walls of the two first reversing rollers 112. One of the first reversing rollers 112 can rotate around its own axis to drive the other first reversing roller 112 to rotate and drive the material tail 210 to reach between the fixed pressing seat 141 and the movable pressing seat 142. The output shaft of the first driving motor 113 is fixedly connected to one end of one of the first reversing rollers 112 to drive the first reversing roller 112 to rotate, thereby improving the degree of automation. The third reversing roller 114 is arranged below the movable pressing seat 142, and its axis is parallel to the axis of the first reversing roller 112, and is used to change the traveling direction of the tail 210. When the end of the tail 210 reaches between the two first reversing rollers 112, the first driving motor 113 stops working, so that the two first reversing rollers 112 can temporarily clamp and fix the end of the tail 210.

[0032] Specifically, in the example, Figure 1 and Figure 2 As shown, the second unwinding mechanism 120 includes a second unwinding roller 121, a fourth drive motor (not shown in the figure), two second reversing rollers 122 and a second drive motor 123. The second unwinding roller 121 can rotate around its own axis to release the material head 220. The output shaft of the fourth drive motor is fixedly connected to one end of the second unwinding roller 121 to drive the second unwinding roller 121 to rotate, thereby improving the degree of automation. The two second reversing rollers 122 are arranged in parallel above the fixed pressing seat 141 to change the travel direction of the material head 220. A material head 220 channel for the material head 220 to pass through is formed between the side walls of the two second reversing rollers 122. One of the second reversing rollers 122 can rotate around its own axis to drive the other second reversing roller 122 to rotate and drive the material head 220 to reach between the fixed pressing seat 141 and the movable pressing seat 142. The output shaft of the second drive motor 123 is fixedly connected to one end of one of the second reversing rollers 122 to drive the second reversing roller 122 to rotate, thereby improving the degree of automation. When the end of the material head 220 passes between the two second reversing rollers 122 for a certain period of time, the second drive motor 123 stops working, so that the two second reversing rollers 122 can temporarily clamp and fix the material head 220.

[0033] Preferably, the first drive motor 113, the second drive motor 123, the third drive motor and the fourth drive motor can be stepper motors with low manufacturing cost. The first drive motor 113, the second drive motor 123, the third drive motor and the fourth drive motor can be servo motors with high motion control accuracy.

[0034] Preferably, the fiber cord calendering joint device also includes a first operating platform 181, a first position adjustment seat 171, a second operating platform 182 and a second position adjustment seat 172. The first operating platform 181 is arranged on a side of the movable pressing seat 142 away from the fixed pressing seat 141, and is used to support the first position adjustment seat 171. The first position adjustment seat 171 is arranged on a side of the movable pressing seat 142 away from the fixed pressing seat 141, and is movably installed on the top surface of the first operating platform 181. The first position adjustment seat 171 is installed with a first unwinding roller 111 and a third driving motor. It should be noted that the opposite ends of the first unwinding roller 111 are rotatably connected to the top surface of the first position adjustment seat 171 through bearings. When the first position adjustment seat 171 moves, it can drive the first unwinding roller 111 to move. The second operating platform 182 is arranged on a side of the fixed pressing seat 141 away from the movable pressing seat 142, and is used to support the second position adjustment seat 172. The second position adjustment seat 172 is arranged on the side of the fixed pressing seat 141 away from the movable pressing seat 142, and is movably installed on the top surface of the second operating table 182. The second unwinding roller 121 and the fourth driving motor are installed on the second position adjustment seat 172. It should be noted that the opposite ends of the second unwinding roller 121 are rotatably connected to the top surface of the second position adjustment seat 172 through bearings. When the second position adjustment seat 172 moves, it can drive the first unwinding roller 111 to move. In this way, the relative positions of the first unwinding roller 111 and the second unwinding roller 121 can be adjusted by means of the first position adjustment seat 171 and the second position adjustment seat 172, and then the relative positions of the material tail 210 and the material head 220 can be adjusted, thereby ensuring the joining effect.

[0035] Preferably, two first slide grooves 1811 are arranged in parallel on the top surface of the first operating table 181, and correspondingly, two first slide rails are arranged in parallel on the bottom surface of the first position adjustment seat 171. The two first slide rails are matched with the two first slide grooves 1811, so that the first position adjustment seat 171 can move along the first slide grooves 1811. Two second slide grooves 1821 are arranged in parallel on the top surface of the second operating table 182, and correspondingly, two second slide rails are arranged in parallel on the bottom surface of the second position adjustment seat 172. The two second slide rails are matched with the two second slide grooves 1821, so that the second position adjustment seat 172 can move along the second slide grooves 1821. In this way, with the help of the first position adjustment seat 171 and the second position adjustment seat 172, the opposite side edges of the material tail 210 can be flush with the opposite side edges of the material head 220, thereby ensuring the joining effect.

[0036] Preferably, the fiber cord calendering joint device further comprises a support frame 190. The two first reversing rollers 112 of the first unwinding mechanism 110, the two second reversing rollers 122 of the second unwinding mechanism 120, the first drive motor 113, and the second drive motor 123 are respectively installed on the top of the support frame 190. The third reversing roller 114 of the first unwinding mechanism 110 is installed on the bottom of the support frame 190.

[0037] Specifically, in the example, Figure 1 and Figure 2 As shown, the film 230 release mechanism 130 includes a second driving cylinder (not shown in the figure) and a clamping member 131. The second driving cylinder is installed on the top of the support frame 190, and the piston rod is fixedly connected to the clamping member 131. The clamping member 131 can clamp the film 230 and drive the film 230 to move between the material tail 210 and the material head 220. The second driving cylinder can drive the clamping member 131 to move up and down between the fixed pressing seat 141 and the movable pressing seat 142, so as to drive the film 230 to move up and down between the fixed pressing seat 141 and the movable pressing seat 142, so as to improve the degree of automation and improve the operation accuracy.

[0038] Preferably, the clamping member 131 may be an electric clamp or a pneumatic clamp.

[0039] It should be noted that, for the fiber cord, during the release process, the tail 210 generates static electricity due to friction. During the transportation process, the head 220 generates static electricity due to friction and carries dust.

[0040] Therefore, the fiber cord calendering joint device further includes a first static eliminator 152 and a second static eliminator 151. The first static eliminator 152 is disposed above the movable pressing seat 142, and is used to eliminate static electricity and dust on the joint surface of the material tail 210. The second static eliminator 151 is disposed above the fixed pressing seat 141, and is used to eliminate static electricity and dust on the joint surface of the material head 220. By eliminating static electricity and dust on the joint surface, the bonding strength of the material tail 210 and the material head 220 can be improved, thereby preventing the material tail 210 and the material head 220 from being disconnected at the bonding point.

[0041] Preferably, the first static eliminator 152 and the second static eliminator 151 are ion wind rods, which can generate a large number of negative ions to neutralize the static charge on the surface of the curtain, thereby achieving the purpose of eliminating static electricity.

[0042] It should be noted that when the first exhaust hole 1411 on the fixed pressing seat 141 generates negative pressure and the material head 220 is attached to the fixed pressing seat 141, the material head 220 may be wrinkled and uneven, which will seriously affect the bonding effect and cannot ensure the uniform thickness of the joint.

[0043] Therefore, the fiber cord calendering joint device also includes a flattening mechanism 160. The flattening mechanism 160 is used to flatten the material head 220 attached to the side of the fixed pressing seat 141 facing the movable pressing seat 142 to eliminate wrinkles, ensure the joint effect of the material head 220 and the material tail 210, and help keep the thickness of the joint consistent.

[0044] Specifically, in the example, Figure 2 and Figure 5 As shown, the flattening mechanism 160 includes a third driving cylinder (not shown in the figure), a support member 161 and a flattening roller 162. The third driving cylinder is vertically arranged, and the piston rod is arranged upward. The top of the third driving cylinder is fixedly connected to the bottom of the support member 161. The flattening roller 162 is rotatably mounted on the top of the support member 161. The side wall of the flattening roller 162 can fit with the material head 220. The support member 161 is driven by the third driving cylinder to move from top to bottom along the fixed pressing seat 141 toward one side of the movable pressing seat 142, so as to drive the flattening roller 162 to move from top to bottom to flatten the material head 220. Since the flattening roller 162 can rotate, the resistance encountered by the flattening roller 162 when moving up and down is effectively reduced, thereby improving the flattening efficiency.

[0045] The working process and principle of the fiber cord calendering joint device are as follows: First, the first position adjustment seat 171 and the second position adjustment seat 172 are used to align the two opposite sides of the material tail 210 with the two opposite sides of the material head 220 .

[0046] Then, the first unwinding roller 111 releases the material tail 210, and the two first reversing rollers 112 temporarily clamp the ends of the material tail 210. The second unwinding roller 121 releases the material head 220, and after a certain period of time, the two second reversing rollers 122 temporarily clamp the material head 220. In this process, the static electricity and dust on the joint surface of the material tail 210 are eliminated with the help of the first static eliminator 152, and the static electricity and dust on the joint surface of the material head 220 are eliminated with the help of the second static eliminator 151. The clamping member 131 of the film 230 release mechanism 130 drives the film 230 to move between the material tail 210 and the material head 220.

[0047] Next, the first air extraction hole 1411 on the fixed pressing seat 141 generates negative pressure, so that the material head 220 is attached to the fixed pressing seat 141 . The second air extraction hole 1421 on the movable pressing seat 142 generates negative pressure, so that the material tail 210 is attached to the fixed pressing seat 141 .

[0048] Afterwards, the flattening roller 162 of the flattening mechanism 160 is attached to the material head 220 and moves from top to bottom to flatten the material head 220 .

[0049] Then, the movable pressing seat 142 moves toward the fixed pressing seat 141 and drives the material tail 210 to move toward the material head 220.
