[0033] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0034] It should be noted that, unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as generally understood by those skilled in the art to which the present application belongs.

[0035] In the present application, unless otherwise specified, the orientation words such as "up, down" are generally directed to the direction shown in the drawings, or are directed to the vertical, perpendicular or gravity direction; similarly, for the convenience of understanding and description, "left, right" is generally directed to the left and right shown in the drawings; "inner, outer" refers to the inner and outer relative to the contour of each component, but the above-mentioned orientation words are not used to limit the present application.

[0036] To address the problem that the zero-degree belt layer of tires is prone to stretching and deformation during transportation in the prior art, this application provides an adjustment device and tire processing equipment having the same.

[0037] like Figures 1 to 7 As shown, the adjustment device includes a frame 10 and a tension adjustment assembly 20. The tension adjustment assembly 20 is mounted on the frame 10 and includes a compression structure 21 and an adjustment structure 22. The compression structure 21 tensions the material by compressing it. The compression structure 21 is vertically movable and moves up and down under the action of the material to maintain a constant surface tension. The adjustment structure 22 is connected to the compression structure 21 and adjusts the surface tension of the material by adjusting the compression force of the compression structure 21. At least two tension adjustment assemblies 20 are provided, and each tension adjustment assembly 20 corresponds to at least two materials.

[0038] Applying the technical solution of this embodiment, the tension adjustment component 20 of the adjustment device is disposed on the frame 10 and includes a pressing structure 21 and an adjustment structure 22. The pressing structure 21 tensions the material 1 by pressing it. The pressing structure 21 is vertically movable and moves up and down under the action of the material 1 to maintain a constant surface tension of the material 1. The adjustment structure 22 is connected to the pressing structure 21 and adjusts the surface tension of the material 1 by adjusting the pressing force of the pressing structure 21. At least two tension adjustment components 20 are provided, with each of the at least two tension adjustment components corresponding to at least two materials 1. Thus, the tension adjustment component 20 in this embodiment has a tension adjustment function, meaning that the adjustment structure 22 can adjust the pressing force of the pressing structure 21 to adapt to the tension requirements of materials 1 of different specifications and sizes. Furthermore, when the pressing force of the pressing structure 21 is adjusted to the required value, the pressing structure 21 can move freely up and down with the material 1, ensuring that the pressing force applied to the material 1 by the pressing structure 21 is constant, thereby maintaining a constant surface tension of the material 1. Meanwhile, the tension adjustment component 20 with the above functions is set to correspond one-to-one with multiple materials 1 to adapt to multiple materials 1 with different incoming tension, thereby ensuring that multiple materials 1 can maintain a suitable and constant surface tension during the conveying process, thus solving the problem that the zero-degree belt layer of the tire is easily stretched and deformed during the conveying process in the prior art, and improving the finished quality of the tire.

[0039] In this embodiment, material 1 is the zero-degree belt layer used in the tire manufacturing process.

[0040] Specifically, compared with the conveying mode of the zero-degree belt in the prior art (i.e., the length of the zero-degree belt between the feeding device and the forming device should be consistent with the distance between the feeding device and the forming device to ensure that the zero-degree belt is in a taut state, and then the tension of the zero-degree belt is adjusted by adjusting the winding and unwinding speed), the length of the zero-degree belt between the feeding device and the forming device in the embodiment should be greater than the distance between the feeding device and the forming device (with a certain margin, the overall belt is bent under the action of its own gravity), so that when the surface tension of the conveying zero-degree belt changes (actually, the length of the zero-degree belt between the feeding device and the forming device changes), the zero-degree belt can drive the extrusion structure 21 to move up and down to ensure that the force applied to the zero-degree belt is always the extrusion force of the extrusion structure 21, thereby ensuring that the conveying tension of the zero-degree belt is always constant.

[0041] In the embodiment, two zero-degree belts are conveyed at the same time, and two tension adjusting assemblies 20 are also provided, which are one-to-one corresponding to the two zero-degree belts.

[0042] Specifically, the two tension adjusting assemblies 20 are arranged at intervals along the width direction of the rack 10.

[0043] It should be noted that the number of tension adjusting assemblies 20 is not limited to this, and can be adjusted according to the working conditions and use requirements. Alternatively, the tension adjusting assembly 20 is three, or four, or five, or six, or seven, or more.

[0044] As shown in Figure 1 and Figure 2 , the adjusting structure 22 includes a counterweight part 221 and a traction part 222, the counterweight part 221 is connected with the extrusion structure 21 through the traction part 222, and the counterweight part 221 applies a pulling force to the extrusion structure 21 through the traction part 222 to adjust the size of the extrusion force. In this way, the above arrangement makes the structure of the adjusting structure 22 simpler and the extrusion force adjustment function more stable on the one hand (i.e., the counterweight part 221 applies a pulling force to the extrusion structure 21 by relying on its own gravity, and its gravity is constant); on the other hand, the worker only needs to replace the counterweight part 221 to realize the extrusion adjustment of the extrusion structure 21 by the adjusting structure 22, thereby reducing the adjustment difficulty of the worker.

[0045] In the embodiment, the traction part 222 is a steel wire rope.

[0046] In the embodiment, the counterweight part 221 is a weight.

[0047] It should be noted that the traction part 222 can be provided with a corresponding hook structure to facilitate the hanging of the weight.

[0048] Specifically, the extrusion structure 21 is located above the material as a whole.

[0049] Specifically, the extrusion force of the extrusion structure 21 applied on the material 1 is actually the resultant force between the gravity of the extrusion structure 21 itself and the gravity of the counterweight part 221 itself, and the resultant force is generated by the gravity as a whole, which has the advantage of being constant.

[0050] It should be noted that the extrusion direction of the extrusion force of the extrusion structure 21 is not limited to this, and a driving structure (such as a driving cylinder) with constant driving force can also be used to drive the extrusion structure 21 to move vertically upward to apply a constant upward extrusion force to the material 1, which can also achieve the above-mentioned function.

[0051] As shown in Figure 1 and Figure 2 , the tension adjusting assembly 20 further comprises a pulley set 23 arranged on the rack 10, the pulley set 23 comprises at least two pulley structures 231, and the at least two pulley structures 231 are arranged in the height direction of the rack 10; the traction part 222 is annular and is sleeved on the at least two pulley structures 231. Among them, the counterweight part 221 and the extrusion structure 21 are arranged on the traction part 222, so that the counterweight part 221 and / or the extrusion structure 21 are driven to move by the traction part 222 during the lifting movement of the extrusion structure 21. In this way, the closed-loop arrangement of the traction part 222 helps to further ensure that the tension of the counterweight part 221 applied to the extrusion structure 21 and the extrusion force of the extrusion structure 21 applied to the material 1 are constant, thereby improving the constant stability of the tension of the tension adjusting assembly 20.

[0052] Specifically, the closed-loop arrangement of the traction part 222 not only realizes the transmission of force between the counterweight part 221 and the extrusion structure 21, but also has the functions of limiting and guiding, that is, the counterweight part 221 and the extrusion structure 21 can only move according to the trajectory of the traction part 222 during movement, which can avoid the change of the tension of the counterweight part 221 applied to the extrusion structure 21 caused by arbitrary swinging of the counterweight part 221, and can also avoid the occurrence of the movement jamming phenomenon of the counterweight part 221, that is, no matter whether the extrusion structure 21 rises or falls, the counterweight part 221 will be pulled by the traction part 222 to move accordingly.

[0053] In the embodiment, the pulley set 23 comprises two pulley structures 231, and the two pulley structures 231 are arranged in the height direction of the rack 10.

[0054] Specifically, the pulley structure 231 is a fixed pulley, and a corresponding annular groove for accommodating the steel wire rope is arranged on the outer circumference of the pulley.

[0055] Specifically, the pulley structure 231 is provided with a mounting bracket for mounting the pulley, and the mounting bracket is arranged on the mounting part 122.

[0056] It should be noted that the number of pulley structures 231 in the pulley block 23 is not limited to this, and can be adjusted according to the working conditions and use requirements. Optionally, the number of pulley structures 231 in the pulley block 23 is three, or four, or five, or six, or seven, or eight, or more.

[0057] In this embodiment, the pulley block 23 is provided with two groups, and the two groups of pulley blocks 23 are provided in one-to-one correspondence with the two tension adjusting assemblies 20.

[0058] As shown in Figure 1 and Figure 2 The rack 10 includes a base 11 and a mounting structure 12, the mounting structure 12 is arranged on the base 11 and has a support part 121 and a mounting part 122, the mounting part 122 is used for mounting the pulley structure 231 and is at least two, the at least two mounting parts 122 are arranged in the height direction of the rack 10, and the at least two pulley structures 231 and the at least two mounting parts 122 are arranged in one-to-one correspondence, the support part 121 is arranged between the adjacent two mounting parts 122 to support the mounting part 122 above the support part 121. Wherein, the support part 121 has a guide through hole 1211, the mounting part 122 has an avoiding hole 1221 for avoiding the traction part 222, the traction part 222 is arranged in the guide through hole 1211 through the avoiding hole 1221, and the counterweight part 221 is located in the guide through hole 1211 to guide the movement direction of the counterweight part 221 through the limiting stop between the hole wall of the guide through hole 1211 and the counterweight part 221 during the movement of the counterweight part 221. In this way, the above arrangement makes the structure of the rack 10 more compact and reasonable, and also forms the corresponding guide through hole 1211 by using the support part 121 of the rack 10, that is, when the traction part 222 drives the counterweight part 221 to move, the counterweight part 221 is located in the guide through hole 1211 as a whole and slides along the extension direction of the guide through hole 1211, so as to further improve the movement stability of the counterweight part 221.

[0059] Specifically, the at least two mounting portions 122 include a first mounting portion 1222 and a second mounting portion 1223, the first mounting portion 1222 includes a first plate-shaped structure 1222a, a second plate-shaped structure 1222b and a third plate-shaped structure 1222c connected with each other, the first plate-shaped structure 1222a and the third plate-shaped structure 1222c are oppositely arranged, the second plate-shaped structure 1222b is located between the first plate-shaped structure 1222a and the third plate-shaped structure 1222c, one end of the first plate-shaped structure 1222a and the third plate-shaped structure 1222c away from the second plate-shaped structure 1222b is arranged on the base 11, and the plate surface of the second plate-shaped structure 1222b close to the base 11 is used for mounting the pulley structure 231, and the supporting portion 121 is arranged on the other plate surface of the second plate-shaped structure 1222b. The second mounting portion 1223 is plate-shaped and arranged on one end of the supporting portion 121 away from the first mounting portion 1222, and the plate surface of the second mounting portion 1223 away from the first mounting portion 1222 is used for mounting the pulley structure 231. In this way, the above arrangement can make the structure of the first mounting portion 1222 and the second mounting portion 1223 simpler, easier to process and implement, and thus reduce the overall processing difficulty and processing cost of the mounting portion 122; on the other hand, the two pulley structures 231 are located on both sides of the first mounting portion 1222 and the second mounting portion 1223, so as to facilitate the sleeving of the annularly arranged traction portion 222.

[0060] In the embodiment, the second plate-shaped structure 1222b and the second mounting portion 1223 are both provided with the avoiding hole 1221.

[0061] In the embodiment, the supporting portion 121 is rod-shaped and vertically arranged, and the inside of the supporting portion 121 is provided with a guide through hole 1211 consistent with the extension direction of the supporting portion 121.

[0062] In the embodiment, the base 11 is plate-shaped, and the first plate-shaped structure 1222a, the second plate-shaped structure 1222b and the third plate-shaped structure 1222c of the first mounting portion 1222 arranged on the base 11 will form a containing space for containing the pulley structure 231 around the base 11.

[0063] As shown in Figures 1 to 3 , the extrusion structure 21 has an extrusion portion 211 for extruding the material, and the extrusion portion 211 is rotatably arranged. During the conveying of the material 1, the extrusion portion 211 rotates through the friction between the outer circumferential surface thereof and the material. In this way, the above arrangement can effectively reduce the friction between the material 1 and the extrusion structure 21 during the conveying of the material 1, so as to avoid the abrasion, even the pulling and damage of the material 1, and thus ensure the conveying quality of the material 1.

[0064] As shown in Figure 1 , Figure 2 and Figure 4As shown, the adjusting device further comprises a first guide structure 30 arranged on the rack 10, the first guide structure 30 is located at one side of the extruding structure 21, the first guide structure 30 has a first matching part 31, the extruding structure 21 has a second matching part 212, one of the first matching part 31 and the second matching part 212 is a protrusion, and the other is a recess, the protrusion extends into the recess and can slide along the extension direction of the recess to guide the movement direction of the extruding structure 21 through the limiting stop between the protrusion and the recess. Wherein, the recess extends along the height direction of the rack 10. In this way, by arranging the first guide structure 30, the movement direction and the attitude of the extruding structure 21 can be guided and limited, thereby improving the movement stability of the extruding structure 21. At the same time, the above arrangement also makes the structure of the first matching part 31 and the second matching part 212 more flexible and diverse to adapt to different working conditions and use requirements, and also improves the processing flexibility of the workers.

[0065] In the embodiment, the first guide structure 30 has two first matching parts 31, and the two first matching parts 31 are respectively arranged corresponding to the second matching parts 212 of the extruding structures 21 of the two tension adjusting assemblies 20.

In this way, the first guide structure 30 and the second guide structure 40 can guide the movement direction of the extruding structure 21 from both sides of the extruding structure 21 respectively, so as to completely avoid the attitude of the extruding structure 21 from being inclined, that is, to improve the extrusion stability of the extruding structure 21 to the material 1. At the same time, the arrangement of the connecting part 213 realizes the cooperation between the extruding structure 21 and the second guide structure 40, and also realizes the connection between the extruding structure 21 and the traction part 222.

[0067] As shown in the figure, Figure 3 And Figure 4As shown, the extrusion structure 21 comprises a roller, the connecting portion 213 is in block shape, the second matching portion 212 is in sliding block shape, the roller comprises a roller body 214 and a rotating shaft 215, the roller body 214 is rotatably sleeved on the rotating shaft 215, the sliding block is rotatably sleeved on the rotating shaft 215 and located at one side of the roller body 214 to form a protrusion, and the connecting portion 213 is rotatably sleeved on the rotating shaft 215 and located at the other side of the roller body 214. Wherein, at least part of the outer circumferential surface of the roller body 214 forms the extrusion portion 211, along the direction from one end to the other end of the roller body 214, the roller body 214 has a diameter expanding section 2141 and a diameter reducing section 2142 connected with each other, so as to form an extrusion protrusion 2143 at the connection between the diameter expanding section 2141 and the diameter reducing section 2142. In this way, the above arrangement makes the roller body 214 as a whole present a gradually changing roller with small diameters at two ends and a large diameter in the middle, that is, the extrusion protrusion 2143 in the middle is mainly used for extruding the material 1, and such arrangement can ensure that the material 1 is uniformly stressed to avoid deformation of the material 1, thereby further improving the conveying quality of the material 1.

[0068] Optionally, along the direction from one end to the other end of the roller body 214, the outer circumferential surface of the roller body 214 is arc-shaped as a whole to ensure that the material 1 can be more closely fitted between the outer circumferential surface of the roller body 214.

[0069] In the embodiment, the first matching portion 31 is a recess, which is actually a groove structure, and the second matching portion 212 is a protrusion, that is, the protrusion is formed by the sliding block.

[0070] As shown in Figure 1 , Figure 2 and Figure 4 , the first guide structure 30 is in rod shape as a whole, and a groove for accommodating the sliding block is arranged inside the first guide structure 30.

[0071] Specifically, the sliding block is in roller shape as a whole and is rotatably sleeved on the rotating shaft 215, and in the process of movement of the extrusion structure 21, the sliding block can rotate with the extrusion structure 21 to improve the smoothness of movement of the extrusion structure 21.

[0072] In the embodiment, two groups of sliding grooves are arranged on the first guide structure 30 and are spaced apart along the width direction of the rack 10, and the two tension adjusting assemblies 20 are respectively located on the two sides of the first guide structure 30 to respectively match with one sliding groove.

[0073] Specifically, the second guide structure 40 is in rod shape and is arranged in the guide hole 2132 of the connecting portion 213.

[0074] In the embodiment, the distance between the connecting portion 213 and the second matching portion 212 (i.e. the length of the rotating shaft 215 between the two) is greater than the length of the roller shaft body 214, so that the roller shaft body 214 can slide along the extension direction of the rotating shaft 215 while rotating. In this way, the roller shaft body 214 can adaptively slide along the extension direction of the rotating shaft 215 under the action of the material 1, so as to further ensure the uniformity of the stress of the material 1.

[0075] Specifically, the specific force analysis on the operation process of the adjusting device in the embodiment is as follows:

[0076] As shown in Figure 5 and Figure 6 , in the initial state (the material 1 has not started to be conveyed, and no corresponding action force G3 is generated), the weight G2 of the counterweight portion 221 is less than the weight G1 of the extrusion structure 21, i.e. G2 < G1, the extrusion structure 21 carries the material 1 to fall on the first mounting portion 1222, and the counterweight portion 221 synchronously rises. When the material 1 is supplied, the material 1 generates the action force G3, the extrusion structure 21 is subjected to the upward force G3, at this time G2 > (G1-G3), the material 1 drives the extrusion structure 21 to move upward and reduce in length, and the counterweight portion 221 synchronously moves downward until the upward action force G3 generated by the surface tension of the material 1 satisfies G3 = G1-G2, the material 1 is static (as shown in Figure 7 ), the size of the surface tension of the material 1 reaches the corresponding requirement, and the two tension adjusting assemblies 20 independently operate and do not affect each other. The workers can adjust the mass of the counterweight portion 221 of the two tension adjusting assemblies 20 (hang different mass weights) according to the size of the incoming tension of the two zero-degree belt layers and the required tension size to give different pressures to the two zero-degree belt layers, so that the adjusting device can adaptively control the tension of the two zero-degree belt layers.

[0077] The application also provides a tire processing equipment, which comprises a feeding device, an adjusting device and a forming device. The adjusting device is located between the feeding device and the forming device and is used for adjusting and maintaining the surface tension of the material constant. The adjusting device is the adjusting device described above.

[0078] Compared with the method for adjusting the surface tension of the zero-degree belt layer in the conveying process in the prior art, the adjusting device in the embodiment has the following advantages:

[0079] 1. The two tension adjustment components 20 (the mutual cooperation between the counterweight 221 and the extrusion structure 21) can realize the adaptive adjustment of the tension of the two zero-degree belt layers with different feeding tensions. This not only avoids the problem of stretching and damage of the zero-degree belt layer during the feeding process, but also enables the two zero-degree belt layers to be conveyed with different tensions, which greatly improves the processing quality of the subsequent finished tires.

[0080] 2. The outer peripheral surface design of the roller body 214 (small at both ends and large in the middle) allows the zero-degree belt layer to fit more tightly with the roller body 214, avoiding the problem of material curling during zero-degree belt layer feeding and further improving the conveying quality of the zero-degree belt layer.

[0081] 3. The adjustment device in this implementation does not require power supply and does not have any active drive devices such as motors or air pumps. The overall structure is simple, easy to process and easy to install, and has the advantages of low cost, space saving and green environmental protection.

[0082] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0083] The tension adjustment component of the adjustment device is mounted on the frame and includes an extrusion structure and an adjustment structure. The extrusion structure tensions the material by extruding it. The extrusion structure is vertically movable and moves up and down under the action of the material to maintain a constant surface tension. The adjustment structure is connected to the extrusion structure and adjusts the surface tension of the material by adjusting the extrusion pressure of the extrusion structure. There are at least two tension adjustment components, each corresponding to at least two materials. Thus, the tension adjustment component in this application has two functions: firstly, it has a tension adjustment function, meaning the adjustment structure can adjust the extrusion pressure of the extrusion structure to adapt to the tension requirements of materials of different specifications and sizes; secondly, when the extrusion pressure of the extrusion structure is adjusted to the required value, the extrusion structure can move freely up and down with the material, ensuring that the extrusion pressure applied to the material remains constant, thereby maintaining a constant surface tension. Meanwhile, the tension adjustment component with the above functions is set to correspond one-to-one with multiple materials to adapt to multiple materials with different incoming tension, thereby ensuring that multiple materials can maintain a suitable and constant surface tension during the conveying process. This solves the problem that the zero-degree belt layer of the tire is prone to stretching and deformation during the conveying process in the prior art, and improves the finished quality of the tire.
