[0001] The present invention relates to the technical field of forming machines, and in particular to a tread forming mechanism, a forming machine and a tread laminating method. Background Art

[0002] The tread of a tire is composed of various rubber compounds, typically a composite material consisting of cap 1, cap 2, base, chimney, wing, and cushion. Of course, the composition will vary depending on the tire's operating conditions; in reality, the tread compositions of truck tires, passenger car tires, and off-highway tires differ.

[0003] In the common tire production process, the tread is produced in the semi-finished product production workshop using composite extrusion equipment. This process has a high degree of integration and can be directly attached to the crown position of the tire blank during later molding. However, it lacks flexibility, and the tread material needs to be replaced with each specification change. In addition, due to the large tread specifications of truck tires and engineering tires, if the curling storage process is used, the tread cannot easily store the heavy tread on the trolley or the storage capacity is very small. If the tread is pre-cut, each change in specification will cause the tread rubber cross-section shape or rubber length to change, and the corresponding tread rubber needs to be re-produced, which reduces its versatility.

The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] In order to solve the problem of low tread feeding efficiency of a tread forming machine in the prior art, the present invention provides a tread forming mechanism.

[0026] Please refer to Figure 1 and Figure 2A tread forming mechanism includes a belt drum assembly, a first feeding assembly 23, a pressure roller device and a second feeding assembly 50, the first feeding assembly 23 is arranged on one side of the belt drum assembly to convey a first tread rubber material to the belt drum assembly, the first tread rubber material including at least one of a base rubber and a buffer rubber sheet; the second feeding assembly 50 is arranged on one side of the belt drum assembly to convey a second tread rubber material to the belt drum assembly, the second tread rubber material including at least one of a crown rubber, a wing rubber and a conductive rubber; the pressure roller device is movably arranged relative to the belt drum assembly to press the first tread rubber material and / or the second tread rubber material onto the belt drum assembly.

[0027] The present invention provides a tread molding mechanism for molding the tread of a tire. The tread molding mechanism arranges multiple feeding components in sequence and at intervals along a preset direction. The belt layer drum assembly can move back and forth along the preset direction. Each feeding component provides a rubber material. The multiple feeding components include a first feeding component 23 and a second feeding component 50. In addition, the first feeding component 23 and the second feeding component 50 can be respectively provided with multiples to feed the belt layer drum 40. The feeding forms of the multiple feeding components can be individually set according to different tire requirements. For example, when the pattern of the tire tread needs to be changed, the conveying position or conveying path of the rubber material on the second feeding component 50 can be directly changed, thereby changing the tire pattern. This avoids the problem in the prior art that multiple colloids need to be replaced when they are combined together and bonded through the belt layer drum assembly. The tread molding mechanism of the present invention is more flexible and more efficient.

[0028] The above-mentioned first feeding assembly and second feeding assembly have different feeding methods so as to be suitable for different types of rubber materials. Among them, the first feeding assembly is mainly used to adhere the first tread rubber material to the belt layer drum. The first tread rubber material can be one or both of base rubber and buffer rubber film, and each can be divided into multiple types. When there are multiple rubber materials, multiple first feeding assemblies are required to convey them one by one. The second feeding assembly is mainly used to wind the second tread rubber material on the belt layer drum. The second tread rubber material can be one or more of crown rubber, wing rubber and conductive rubber, which can be selected according to tire requirements.

[0029] The wing rubber is located on both sides of the crown rubber and the base rubber.

[0030] The pressing roller device is movably arranged relative to the belt drum so as to move close to the belt drum and press the first tread rubber material onto the belt drum after the first tread rubber material is attached to the belt drum, and similarly press the second tread rubber material.

[0031] According to one embodiment, the belt drum assembly is movably arranged relative to both the first feeding assembly 23 and the second feeding assembly 50 .

[0032] In addition, the first feeding assembly 23 and the second feeding assembly 50 can also move relative to the belt drum assembly along a direction perpendicular to the second track assembly.

[0033] According to another embodiment, the first feeding assembly and the second feeding assembly are located on the same side of the belt drum or are respectively arranged on both sides of the belt drum.

[0034] The tread forming mechanism also includes a second track assembly 20, which is arranged on the same side of the first feeding assembly 23 and the second feeding assembly 50, wherein the second track assembly 20 is provided with a first feeding station and a second feeding station, and the belt layer drum assembly is movably arranged on the second track assembly 20 to move between the first feeding station and the second feeding station.

[0035] According to one embodiment, the second track assembly 20 can be a linear guide rail or a circular guide rail. In addition, the second track assembly 20 can include multiple guide rails. The belt layer drum assembly includes a belt layer drum 40. The belt layer drum 40 is set on a sliding frame. The sliding frame is slidingly connected to the second track assembly 20 to drive the belt layer drum assembly to move along the guide rail, wherein the first feeding station corresponds to the first feeding assembly 23. When the belt layer drum assembly moves to the first feeding station, the first feeding assembly 23 feeds the belt layer drum 40.

[0036] According to another embodiment, when the first feeding assembly 23 and the second feeding assembly 50 are respectively located on both sides of the belt drum, the second track assembly is located between the first feeding assembly 23 and the second feeding assembly 50 .

[0037] Preferably, the first feeding assembly 23 and the second feeding assembly 50 are symmetrically arranged on both sides of the belt drum. In this case, there is no need to set up a second track assembly, and the belt drum does not need to be moved to complete the bonding of the first tread rubber and the second tread rubber at the same position.

[0038] The second feeding component 50 adopts an extruder. Preferably, the second feeding component 50 adopts an extrusion winding machine.

[0039] When the second tread rubber material includes multiple rubber materials, the first working material assembly is provided with multiple extruders to correspond to the multiple rubber materials one by one, so as to respectively transport each rubber material to the belt layer drum for winding, wherein the multiple extruders can be arranged on the same side of the belt layer drum assembly or evenly distributed on both sides.

[0040] According to the same principle, when the first tread rubber material includes multiple rubber materials, multiple first material supply assemblies are provided to respectively convey corresponding rubber materials, wherein the multiple first material supply assemblies can be arranged on the same side of the belt drum assembly or evenly distributed on both sides.

[0041] The belt drum assembly is rotatably arranged, wherein the first feeding assembly 23 is used for applying the first tread rubber material to the belt drum assembly, and / or the second feeding assembly 50 is used for winding the second tread rubber material onto the belt drum assembly.

[0042] The first feeding assembly and the second feeding assembly have different feeding methods. The first feeding assembly is used to directly adhere the first tread rubber material to the belt drum. During operation, one end of the first tread rubber material contacts the belt drum, and then the belt drum rotates one circle to adhere the first tread rubber material to the belt drum; the second feeding assembly adopts a winding method to feed. Specifically, one end of the second tread rubber material contacts one side of the circumferential surface of the belt drum, and then the belt drum rotates continuously to allow the second tread rubber material to wind from one side to the other side, so as to be evenly distributed on the outer surface of the belt drum. During the process, the belt drum needs to rotate at a constant speed.

[0043] The tread building mechanism further includes a material guide assembly 235, which is disposed at an end of the first feeding assembly 23 away from the belt drum assembly to guide the base rubber and deliver it to the first feeding assembly 23. The tread building mechanism further includes an adjustment assembly, which is movably disposed on the first feeding assembly 23 to adjust the position of the base rubber on the first feeding assembly 23.

[0044] like Figure 2 As shown, the material guide assembly 235 is arranged at one end of the conveyor belt assembly. The material guide assembly 235 is used to guide the rubber material wound on the rubber material reel and then convey it to the conveyor belt assembly. The rear template performs preliminary correction and guidance on the rubber material, and the rubber material continues to move forward to the position of the first detection assembly. The first detection assembly is a fixed-length switch. After detecting that the rubber material has started to move for a preset time, the first detection assembly controls the cutting assembly to cut the rubber material.

[0045] The tread building mechanism further includes: a cutting assembly, disposed on the first feeding assembly 23, for cutting the first tread rubber material; a first detection assembly, disposed above the first feeding assembly 23, for controlling the cutting assembly to cut a predetermined length of the first tread rubber material by detecting the length of the first tread rubber material traveling on the first feeding assembly 23. The tread building mechanism further includes a second detection assembly, disposed on the first feeding assembly 23, for detecting the presence of belt rubber material on the first feeding assembly 23; and a controller, connected to the second detection assembly and further connected to each of the pressure roller devices, for controlling the movement of each of the pressure roller devices based on detection information from the second detection assembly.

[0046] The present invention also provides a forming machine, comprising a tread forming mechanism, and the tread forming mechanism is the tread forming mechanism mentioned above.

[0047] The present invention also provides a tread laminating method, which utilizes the above-mentioned tread forming mechanism for laminating. The tread laminating method includes: when the belt drum assembly is located at a first laminating station, a first feeding assembly 23 conveys a first tread rubber material to the first laminating station and laminarizes the first tread rubber material on the belt drum assembly; when the belt drum assembly is located at a second laminating station, a second feeding assembly 50 conveys a second tread rubber material to the second laminating station and laminarizes the second tread rubber material on the belt drum assembly. The first laminating station and the first feeding assembly are each provided in plurality, the plurality of first laminating stations being provided in a one-to-one correspondence with the plurality of first feeding assemblies, and the plurality of first laminating stations and the plurality of first feeding assemblies being arranged sequentially along a preset direction; and / or the second laminating station and the second feeding assembly are each provided in plurality, the plurality of second laminating stations being provided in a one-to-one correspondence with the plurality of second feeding assemblies, and the plurality of second laminating stations and the plurality of second feeding assemblies being arranged sequentially along a preset direction.

[0048] The tread bonding method of the present invention can selectively set up multiple first feeding assemblies and multiple second feeding assemblies according to the amount of rubber materials to be bonded. For example, when there are multiple types of rubber materials to be extruded, multiple bonding stations cooperating with the extruder are set up so that the various rubber materials extruded by the extruder are wound around the belt layer drum in turn. The second tread rubber material suitable for the extruder can be CAP conductive glue, or multiple bonding stations cooperating with the first feeding assembly and multiple first feeding assemblies can be set up, so that the various rubber materials are transported to the bonding station in turn to bond the rubber materials to the belt layer drum.

[0049] In addition, the first laminating station and the second laminating station of the present invention can be different stations or the same station. When located at different stations, the belt layer drum is moved between the first laminating station and the second laminating station. When the first laminating station and the second laminating station overlap, at this time, the first work-material assembly and the second material feeding assembly are symmetrically arranged on both sides of the belt layer drum, and the belt layer drum does not need to be moved.

[0050] The main process steps are as follows:

[0051] The material guide assembly 235 guides the tread rubber material from the I-wheel material roll, and after being cut to a fixed length and corrected and straightened, it is transported to the front tread bonding template.

[0052] The belt drum assembly includes a belt layer drum 40 and a belt layer drum 40 chassis, which is movably mounted on the second track assembly and can move horizontally on the second track assembly as a whole. At the same time, the belt layer drum assembly is also provided with a lifting mechanism, which is driven and connected to the belt layer drum 40 so as to be able to adjust the position of the belt layer drum 40 in the vertical direction and realize up and down movement.

[0053] The material storage device 51 adopts a tread rubber material tray or a guide device to guide the tread rubber material from the tray or the I-wheel material roll, and reaches the extruder feed port through the extruder rubber conveyor belt. The rubber material enters the extruder barrel. After plasticization, the rubber material can flow out from the die plate at the front end of the barrel in a certain shape, and then be fitted and wound on the belt drum according to the control command.

[0054] The movable belt drum 40 casing and the belt drum stop before the tread laminating feeding rack, and when the tread feeding device and the center line of the belt drum coincide with each other, the laminating of the tread rubber material can be completed.

[0055] The movable belt drum 40 chassis moves leftward along the second track assembly to the tread extrusion, winding and laminating position, and is ready to start the winding and laminating of the rubber material.

[0056] The tread extrusion winding device moves forward and approaches the belt drum. After the front extruder nozzle moves to the winding starting position, the belt drum moves horizontally left and right and rotates to complete the winding of the tread strip. After the winding is completed, the overall bonding of the tread rubber material is completed.

[0057] This invention aims to improve production efficiency by developing a highly efficient tread winding and laminating system that meets the specific production process requirements. This feeding system utilizes a coiled material system for storing common rubber. The length of this portion of the material can be freely adjusted based on the material's specifications, while variable lengths can be achieved through the material winding process. This material winding process can accommodate treads of varying specifications and shapes, ensuring high production efficiency while enabling flexible configuration of the material's appearance and shape, simplifying the complexity of the preceding production process.

[0058] The winding rubber can be freely set according to the customer's tire formula. The configuration of tread bonding rubber and winding extruder is rich and varied. Currently, the following methods are often used to protect:

[0059] The first tread rubber material of the first feeding assembly is adhered to the belt drum in a bonding manner. The first tread rubber material may include the following rubber materials: a base rubber, a base rubber and a buffer rubber sheet, multiple base rubbers and a buffer rubber sheet, a base rubber and multiple buffer rubber sheets, and a combination of multiple base rubbers and multiple buffer rubber sheets.

[0060] The second tread rubber material of the second feeding assembly is adhered to the belt drum or the first tread rubber material in a winding manner. The second tread rubber material may include the following rubber materials: a crown rubber, a crown rubber and a conductive rubber, multiple crown rubbers and a conductive rubber, a crown rubber and multiple conductive rubbers, and a combination of multiple crown rubbers and multiple conductive rubbers.

[0061] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0062] The present invention provides a new tread forming mechanism, which divides the tread into two or more workstations, each of which uses lamination or winding to form the tread. The tread rubber is divided into multiple types of rubber, and each type of rubber corresponds to a feeding assembly. Among them, some rubber is attached to the belt drum assembly by lamination, such as the base rubber is lamination, and some rubber is wound onto the belt drum assembly by winding, such as CAP conductive rubber. This part of the rubber is fed in a curling manner, and then automatically fixed in length, cut, and then attached to the belt drum; the tread is attached by winding using an extruder. The wound tread is highly flexible and can meet the winding requirements of treads of different shapes. This can not only meet the requirements of storing more rubber, but also meet the requirements of winding and laminating of treads with various cross-sectional shapes.

[0063] The tread forming mechanism of the forming machine is arranged on one side of the forming machine unit, and includes a movable belt drum assembly, a first feeding assembly 23 and a second feeding assembly 50, wherein the first feeding assembly 23 adopts a tread laminating feeding device, and the second feeding assembly 50 adopts a tread extrusion winding device; Figure 1 As shown, the tread extrusion and winding device is located behind the belt drum 40; the tread application and feeding device is also located behind the belt drum. The centerline of the tread application and feeding device is perpendicular to the belt drum. The tread extrusion and winding device can be placed perpendicular to the axis of the belt drum or at a certain angle.

[0064] The outstanding feature of the present invention is that it can realize a flexible tread feeding method for the tread forming mechanism of the forming machine, which can meet the needs of multiple tread specifications. The tread bottom rubber (base rubber) can be set in length according to the tire formula on the tread feeding device, and then automatically cut and bonded; the tread extrusion and winding device can wind the required shape according to the tire formula. When the tire blank does not change the rubber raw material formula, there is no need to replace the rubber and semi-finished rubber. In the past, the tread feeding method used pre-cut tread bonding. After changing the tire formula, this situation generally requires adjustment due to changes in the tread length and tread cross-sectional shape due to the change in the tire formula, and further requires replacement of the semi-finished rubber. The current solution can avoid this problem, thereby improving production efficiency and reducing the labor intensity of workers.

[0065] The tread forming mechanism of the present invention can avoid the shortcomings of the current pre-cut tread. The pre-cut tread is only produced for a formula of a specific specification. When the tire formula is changed, even if only the rubber length is changed, the pre-cut tread shutter car needs to be replaced as a whole. In addition, the pre-cut tread requires workers to participate in the bonding, and it is difficult to achieve automatic jointing. This solution can effectively avoid these shortcomings.

[0066] All-steel radial truck tire treads are generally thick and long, resulting in a limited amount of stock stored in rolls, necessitating frequent replacement of the unwinding trolley. The tread forming mechanism of this invention combines coil unwinding with extrusion winding, addressing both the frequent stock changes caused by limited unwinding stock and the lengthy tread winding process.
