Description

Technical Field

[0001] This invention relates to the field of tire manufacturing technology, specifically to a tire carcass feeding rack for a small-sized tire forming machine. Background Technology

[0002] Small-size tires typically refer to tires with a rim diameter of 18 inches or less. They are mainly suitable for small cars, compact cars, some SUVs, and microcars. These tires have a narrower tread and a relatively high aspect ratio. In the process of forming small-size tires, materials such as the inner liner and ply layer need to be bonded to the forming drum in a specific process order to produce a green tire. The quality of the ply layer joints directly determines the yield rate of the finished tire. In existing material supply equipment, the ply layer needs to be cut into small sections by a cutting device, then joined together to form a whole roll of ply. After being conveyed to the forming machine, it needs to be cut to the specified length according to the tire specifications before it can be conveyed to the forming drum for bonding.

[0003] However, the feeding method of existing tire carcass feeders causes the ply fabric to undergo a cutting-jointing-cutting process. The fixed-length cutting position on the forming machine is easily too close to the joint of the ply roll itself, resulting in two adjacent joints in the same ply layer of the tire carcass after bonding. This can easily lead to quality defects such as delamination and cracks in the tire. Therefore, those skilled in the art have provided a small-sized tire carcass feeder for a tire forming machine to solve the problems mentioned in the background art. Summary of the Invention

[0004] The purpose of this invention is to provide a tire carcass feeding rack for a small-sized tire forming machine, in order to solve the problem mentioned in the background art that the feeding method of the existing tire carcass feeding rack causes the cord fabric to undergo a cutting-jointing-cutting process. The fixed-length cutting position on the forming machine is easily too close to the joint of the cord fabric roll itself, resulting in two adjacent joints in the same cord layer of the tire carcass after bonding, and the tire is prone to quality defects such as delamination and cracks.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A small-sized tire forming machine tire body feeding frame includes an inner liner feeding mechanism and a sorting conveyor belt. The inner liner feeding mechanism and the sorting conveyor belt are arranged sequentially according to the material movement direction. At least one set of curtain fabric feeding mechanism is arranged on both sides of the sorting conveyor belt. The lining feeding mechanism includes, in sequence according to the material movement direction, an lining guiding component for guiding the lining, an lining cutting component for cutting to a fixed length to form the lining layer, and an lining conveyor belt for conveying the lining layer.

[0006] As a further embodiment of the present invention: the fabric feeding mechanism includes, in sequence according to the material movement direction, a fabric guiding assembly for unfolding and conveying the fabric roll and a fabric conveyor belt for conveying the fabric. A fabric cutting assembly for cutting continuous fabric into independent fabric layers is arranged across the fabric conveyor belt. A fabric transfer robot for transferring the fabric layers to the sorting conveyor belt is arranged above the fabric conveyor belt. The fabric guiding assembly can ensure continuous fabric supply, the fabric conveyor belt can realize stable fabric conveying, the fabric cutting assembly can complete fabric cutting, and the fabric transfer robot realizes fabric layer transfer. The four components work together to realize automated fabric layer feeding and avoid errors caused by manual intervention.

[0007] As a further aspect of the present invention: an angle adjustment component is provided between the fabric cutting component and the fabric conveyor belt for adjusting the included angle between the two. The included angle adjustment component can flexibly adjust the included angle between the fabric cutting component and the fabric conveyor belt to achieve cutting of the fabric at different angles, adapt to the different requirements of small-sized tires of different specifications for the angle of the fabric layer, and improve the versatility of the equipment.

[0008] As a further embodiment of the present invention: the angle adjustment component includes a mounting frame, on which two annular guide rails are provided. The two annular guide rails are distributed on both sides of the fabric conveyor belt. The mounting frame provides a stable mounting base for the annular guide rails, and the annular guide rails provide guidance for the sliding adjustment of the fabric cutting component, ensuring that the angle adjustment of the fabric cutting component is smooth and accurate, and ensuring that the cutting angle meets the preset requirements.

[0009] As a further embodiment of the present invention: the mounting frame is fixedly connected to the curtain conveyor belt, and the mounting frame and the curtain conveyor belt are securely connected to prevent the angle adjustment component from shifting during operation, thus ensuring the stability of the curtain cutting component when adjusting the angle.

[0010] As a further embodiment of the present invention: the two ends of the curtain cutting component are slidably connected to two annular guide rails respectively. The annular guide rails are provided with locking components for locking the curtain cutting component, so that the curtain cutting component can slide flexibly along the annular guide rails, which is convenient for angle adjustment. The locking components can fix the curtain cutting component after the angle adjustment is completed, so as to prevent displacement during the cutting process.

[0011] As a further aspect of the present invention: the annular guide rail is provided with markings for angle reference, which provides an intuitive reference for the angle adjustment of the curtain cutting component, making it easy for operators to quickly and accurately adjust to the preset angle and reduce angle adjustment errors.

[0012] As a further embodiment of the present invention: the curtain transfer robot includes a mounting base, a first turntable is provided on the mounting base, a first extension arm is provided at one end of the first turntable, a second turntable is provided at one end of the first extension arm, a second extension arm is provided on the outer side of the second turntable, and a gripping component for gripping the curtain layer is provided at the lower part of the second extension arm.

[0013] As a further embodiment of the present invention: the mounting base is fixedly connected to the curtain conveyor belt, and the curtain transfer robot is stably installed above the curtain conveyor belt to ensure the stability of the robot during operation, avoid shaking during the transfer process that would cause the curtain layer to fall or shift, ensure the accuracy of the curtain layer transfer, and improve the continuity of material supply.

[0014] Compared with the prior art, the beneficial effects of the present invention are: By incorporating a fabric feeding mechanism, the fabric can be cut into pre-defined fabric layers, eliminating the "cutting-joining-cutting" process in traditional feeding equipment. This avoids the problem of fabric joints being too close together, ensuring that each layer of fabric has only one joint, reducing defects such as tire delamination and cracks, and improving the finished product qualification rate. The fabric feeding mechanism on both sides of the sorting conveyor belt operates in parallel with the inner liner feeding mechanism, shortening material supply waiting time and improving production efficiency. The angle adjustment component can flexibly adjust the angle of the fabric cutting component through the ring guide rail, and with the marking scale positioning, it can adapt to the differentiated needs of different tire specifications, improving the equipment's versatility.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1-2 In this embodiment of the invention, a small-sized tire forming machine tire body feeding frame includes an inner liner feeding mechanism 1 and a sorting conveyor belt 3. The inner liner feeding mechanism 1 and the sorting conveyor belt 3 are arranged sequentially according to the material movement direction. At least one set of curtain feeding mechanism 2 is arranged on both sides of the sorting conveyor belt 3. The inner lining feeding mechanism 1 includes, in sequence according to the material movement direction, an inner lining guiding component 101 for guiding the inner lining, an inner lining cutting component 102 for cutting to a fixed length to form the inner lining layer 4, and an inner lining conveyor belt 103 for conveying the inner lining layer 4. The inner lining guiding component 101 unfolds the rolled inner lining material to avoid wrinkles or breakage during the unfolding process, ensuring the continuity of the inner lining supply. The inner lining cutting component 102 is used to cut the unfolded inner lining to a fixed length according to the preset tire specifications, ensuring that the length of each inner lining layer 4 meets the production requirements. The inner lining conveyor belt 103 conveys the cut inner lining layer 4 to the sorting conveyor belt 3 to prevent the inner lining layer 4 from shifting or falling during the conveying process, ensuring the continuity and stability of the inner lining supply. The three components cooperate in sequence according to the material movement direction to realize the automated processing and conveying of the inner lining from the roll material to the inner lining layer 4.

[0019] Please see Figure 3In this embodiment of the invention, the fabric feeding mechanism 2 includes, in sequence according to the material movement direction, a fabric guiding assembly 201 for unrolling and conveying the fabric roll and a fabric conveyor belt 202 for conveying the fabric. A fabric cutting assembly 203 for cutting continuous fabric to form independent fabric layers 5 is transversely arranged above the fabric conveyor belt 202. A fabric transfer robot 205 for transferring the fabric layers 5 to the sorting conveyor belt 3 is arranged above the fabric conveyor belt 202. The fabric guiding assembly 201 is used to smoothly and continuously unroll the rolled fabric, ensuring the integrity of the original fabric structure and providing a stable material base for subsequent fabric conveying and cutting. The fabric conveyor belt 202 is used to receive the fabric. The guide assembly 201 conveys the continuous fabric at a stable speed to the cutting position, ensuring the positional accuracy of the fabric during cutting. The fabric cutting assembly 203 precisely cuts the continuously conveyed fabric according to the preset tire specifications, forming independent fabric layers 5 that meet the size requirements. The fabric transfer robot 205 grabs the cut fabric layers 5 and transfers them to the sorting conveyor belt 3, placing them in the preset position on the sorting conveyor belt 3, forming an orderly cooperation with the inner liner layer 4. The four work together to realize the automation of the fabric layer 5 feeding, reduce the error caused by manual operation, improve the efficiency and consistency of fabric feeding, ensure the stability of tire body feeding, and improve the qualified rate of tire forming.

[0020] Please see Figure 3 and Figure 5 In this embodiment of the invention, an angle adjustment component 204 is provided between the fabric cutting component 203 and the fabric conveyor belt 202 to adjust the included angle between them. The angle adjustment component 204 flexibly adjusts the included angle between the fabric cutting component 203 and the fabric conveyor belt 202 to achieve different angles of fabric cutting, adapting to the different requirements of small-sized tires of different specifications for the angle of the fabric layer 5, improving the versatility of the equipment. The angle adjustment component 204 is used to connect the fabric cutting component 203 and the fabric conveyor belt 202, providing an adjustable installation base for the fabric cutting component 203. It can flexibly adjust the tilt angle of the fabric cutting component 203, thereby adjusting the fabric cutting angle. The cutting angle can be quickly adjusted according to the different requirements of small-sized tires of different specifications for the angle of the fabric layer 5, without the need to replace the cutting equipment or readjust the whole machine, greatly improving the versatility and flexibility of the equipment, reducing the debugging cost and time when switching production of different tire specifications, and improving production efficiency.

[0021] Please see Figure 6In this embodiment of the invention, the angle adjustment component 204 includes a mounting frame 2041. Two annular guide rails 2042 are mounted on the mounting frame 2041, distributed on both sides of the fabric conveyor belt 202. The mounting frame 2041 provides a stable mounting base for the annular guide rails 2042, and the annular guide rails 2042 provide guidance for the sliding adjustment of the fabric cutting component 203, ensuring smooth and accurate angle adjustment of the fabric cutting component 203 and guaranteeing that the cutting angle meets preset requirements. The mounting frame 2041 serves as the basic mounting structure for the angle adjustment component 204, securely fixing the annular guide rails 2042 to both sides of the fabric conveyor belt 202, while also providing indirect support for the fabric cutting component 203. The installation support prevents the angle adjustment component 204 from shaking or shifting during operation, ensuring the overall stability of the angle adjustment component 204. The annular guide rail 2042 provides guidance for the angle adjustment of the curtain fabric cutting component 203, guiding the curtain fabric cutting component 203 to slide smoothly along the annular track, ensuring smooth movement of the curtain fabric cutting component 203 during angle adjustment without jamming or shifting, and ensuring the accuracy of angle adjustment. The two work together to ensure that the angle adjustment component 204 can stably achieve the angle adjustment of the curtain fabric cutting component 203, thereby ensuring that the curtain fabric cutting angle meets the preset requirements, avoiding unqualified curtain layer 5 due to angle adjustment deviation, and improving the quality of curtain fabric supply.

[0022] In this embodiment, the mounting frame 2041 is fixedly connected to the curtain conveyor belt 202, which securely connects the mounting frame 2041 and the curtain conveyor belt 202 to prevent the angle adjustment component 204 from shifting during operation and to ensure the stability of the curtain cutting component 203 when adjusting the angle.

[0023] It should be noted that the two ends of the curtain cutting component 203 are slidably connected to two annular guide rails 2042 respectively. The annular guide rails 2042 are equipped with locking components for locking the curtain cutting component 203, so that the curtain cutting component 203 can slide flexibly along the annular guide rails 2042, which is convenient for angle adjustment. The locking components can fix the curtain cutting component 203 after the angle adjustment is completed, so as to prevent displacement during the cutting process.

[0024] Specifically, the circular guide rail 2042 is equipped with a scale 2043 for angle reference, which provides an intuitive reference for the angle adjustment of the curtain cutting component 203, making it easy for operators to quickly and accurately adjust to the preset angle and reduce angle adjustment errors.

[0025] Please see Figure 4In this embodiment of the invention, the curtain fabric transfer robot 205 includes a mounting base 2051, on which a first turntable 2052 is provided. A first extension arm 2053 is provided at one end of the first turntable 2052, and a second turntable 2054 is provided at one end of the first extension arm 2053. A second extension arm 2055 is provided on the outer side of the second turntable 2054. A gripping component for gripping the curtain fabric layer 5 is provided at the lower part of the second extension arm 2055. The mounting base 2051 serves as the basic mounting structure for the curtain fabric transfer robot 205, securely mounting the entire robot in a preset position and providing stable support for the various moving parts of the robot, ensuring the overall stability of the robot during operation. The first turntable 2052 is used to achieve horizontal rotation of the first extension arm 2053, driving the first extension arm 2053, the second turntable 2054, the second extension arm 2055, and the gripping component to rotate around the mounting base 2051, expanding the gripping and transfer range of the robot. The first extension arm 2053 extends the machine... The movement radius of the robotic arm drives the second turntable 2054, the second extension arm 2055, and the gripping component to move away from or towards the mounting base 2051, further expanding the working range of the robotic arm and adapting to the distance between the curtain conveyor belt 202 and the sorting conveyor belt 3. The function of the second turntable 2054 is to realize the rotation of the second extension arm 2055, which can adjust the orientation of the gripping component to ensure that the gripping component can accurately align with the curtain layer 5, and at the same time facilitate the precise placement of the curtain layer 5 in the preset position on the sorting conveyor belt 3. The second extension arm 2055 is used to further extend the working radius of the robotic arm, and works with the first extension arm 2053 to realize multi-dimensional position adjustment, ensuring that the gripping component can flexibly reach the gripping position of the curtain layer 5 and the placement position of the sorting conveyor belt 3. The function of the gripping component is to grip the cut curtain layer 5, ensure the structural integrity of the curtain layer 5, realize the multi-degree-of-freedom movement of the curtain transfer robotic arm 205, and ensure that the curtain layer 5 can be transferred from the curtain conveyor belt 202 to the sorting conveyor belt 3.

[0026] In this embodiment, the mounting base 2051 is fixedly connected to the fabric conveyor belt 202, and the fabric transfer robot 205 is securely installed above the fabric conveyor belt 202. This ensures the stability of the robot during operation, prevents the fabric layer 5 from falling or shifting due to shaking during transfer, ensures accurate transfer of the fabric layer 5, and improves the continuity of material supply. The fixed connection between the mounting base 2051 and the fabric conveyor belt 202 can firmly fix the fabric transfer robot 205 in a preset position above the fabric conveyor belt 202, so that the robot and the fabric conveyor belt 202 form a stable whole. This prevents the robot from shaking during multi-degree-of-freedom movement or vibration generated by equipment operation, ensures the stability of the robot during operation, and prevents the gripping component from dropping the fabric layer 5 or shifting during transfer due to shaking. This ensures the continuity of fabric supply, reduces material waste and supply interruption caused by transfer errors, and improves the efficiency and quality of tire body supply.

[0027] After the equipment is started, the PLC programmable controller realizes the coordinated control of the inner lining feeding mechanism 1, the cord fabric feeding mechanism 2, and the sorting conveyor belt 3. Parameters such as the cutting length of the inner lining layer 4 and the cutting width and angle of the cord fabric layer 5 are preset to adapt to the rapid switching production of different tire specifications without repeated debugging. The specific working process is as follows: The inner lining feeding mechanism 1 unfolds the inner lining roll according to the material movement direction, and the inner lining guide assembly 101 conveys it to the inner lining cutting assembly 102. The inner lining cutting assembly 102 cuts the material to form the required inner lining layer 4. Subsequently, the inner lining... The lining conveyor belt 103 smoothly transports the fixed-length inner lining layer 4 to the sorting conveyor belt 3. Simultaneously, the fabric feeding mechanisms 2 on both sides of the sorting conveyor belt 3 operate synchronously, forming a parallel feeding process with the inner lining feeding mechanism 1. The fabric guiding assembly 201 smoothly unfolds the fabric roll and continuously transports it to the fabric conveyor belt 202. The operating speeds of the fabric conveyor belt 202, the fabric guiding assembly 201, and the fabric cutting assembly 203 are precisely matched to ensure no slippage or pulling during fabric transport, thus preserving the integrity of the original fabric structure. The angle adjustment assembly 204 adjusts the angle according to a preset... The tire specifications are displayed. The annular guide rail 2042 on the mounting bracket 2041 drives the fabric cutting assembly 203 to rotate flexibly. The operator can quickly adjust the cutting angle to the preset value using the laser-engraved markings 2043 on the annular guide rail 2042. After adjustment, the locking assembly fixes the fabric cutting assembly 203 to prevent angle deviation during cutting. The fabric cutting assembly 203 works in conjunction with the fabric conveyor belt 202 to cut the continuous fabric into independent fabric layers 5 according to the preset width and angle. After cutting, the fabric transfer machinery is started. Hand 205, through the multi-degree-of-freedom coordinated action of the first turntable 2052, the first extension arm 2053, the second turntable 2054 and the second extension arm 2055 on the mounting base 2051, drives the lower gripping component to move precisely above the curtain layer 5, and runs smoothly along the preset trajectory, accurately transferring the curtain layer 5 to the sorting conveyor belt 3, ensuring that the long side of the curtain layer 5 is parallel to the length direction of the sorting conveyor belt 3. After receiving the inner lining layer 4 and the curtain layer 5, the sorting conveyor belt 3 synchronously transports the two to the forming drum at a stable speed, thereby completing the material feeding process.

[0028] In summary, by setting up the fabric feeding mechanism 2, the fabric can be cut into fabric layers 5 of preset specifications, eliminating the "cutting-joining-cutting" process in traditional feeding equipment, avoiding the problem of fabric joints being too close, ensuring that each layer of fabric has only one joint, reducing defects such as tire delamination and cracks, and improving the finished product qualification rate. The fabric feeding mechanism 2 on both sides of the sorting conveyor belt 3 and the inner liner feeding mechanism 1 operate in parallel, shortening the material supply waiting time and improving production efficiency. The angle adjustment component 204 can flexibly adjust the angle of the fabric cutting component 203 through the annular guide rail 2042, and coordinate with the marking scale 2043 for positioning, adapting to the differentiated needs of different tire specifications and improving the equipment's versatility.

[0029] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
