Description

Technical Field

[0001] The invention relates to the technical field of tire manufacturing, and in particular to a layout structure of a second-stage tire molding machine. Background Art

[0002] In the second-stage molding machine of the traditional two-step molding method, the cylindrical tire blank produced by the first-stage molding machine is placed on the shaping drum of the second-stage molding machine, and is combined with the supporting components such as the belt layer, cap strip, tread, etc. completed on the bonding drum of the second-stage molding machine (the completed components are clamped and transferred to the cylindrical tire blank positioned on the shaping drum by a transfer ring). After the tire blank is inflated, pre-shaped, and shaped and rolled, it is made into a mechanical device for a green tire before vulcanization.

[0003] The second stage tire forming machine generally places the cylindrical tire produced by the first stage forming machine on the forming drum of the second stage forming machine, and after the tire is inflated, the tile is propped up for pre-forming, a single steel wire is wound (similar to the crown strip bonding in the ordinary two-stage method), the tread is bonded, and the tire is formed into a mechanical device before vulcanization. Figure 1 As shown, the current second-stage tire forming machine structural layout mainly includes a steel wire rubber coating device 1, a rubber coated steel wire storage device 2, a rubber coated steel wire steering assembly 3, a rubber coated steel wire winding head moving device 4, a forming drum case and drum 5, a forming drum moving device 6, a rubber coated steel wire winding head 7, a combined pressure roller 8, a tread feeding rack 9 and a tread guide device 10. The specific forming process is as follows: the steel wire is coated with rubber by passing through the steel wire rubber coating device 1; a portion of the rubber coated steel wire is pre-stored by the rubber coated steel wire storage device 2; the rubber coated steel wire is pulled onto the rubber coated steel wire winding head 7 through the rubber coated steel wire steering assembly 3; the rubber coated steel wire winding head 7 can be moved left and right under the action of the rubber coated steel wire winding head moving device 4, and the initial position of the rubber coated steel wire winding head 7 is as shown in FIG. Figure 1 As shown, it is aligned with the center of the tread feeding rack 9; the tread rubber material is guided by the tread guiding device 10, and the tread rubber material is fixed in length and cut through the tread feeding rack 9; the operator places the cylindrical tire blank produced by the first station of the molding machine on the molding drum 5 of the second stage molding machine, and pre-shapes the tire blank after the tire blank is inflated and supported by the tiles; the rubber-coated steel wire head winds the rubber-coated steel wire onto the pre-shaped tire blank, and after the rubber-coated steel wire winding is completed, the rubber-coated steel wire winding head 7 can be moved to the right side under the action of the rubber-coated steel wire winding head moving device 4; the tread feeding rack 9 is extended to carry out and complete the bonding of the tread rubber material; the molding drum box and drum 5 are moved to the rolling station, and the tread rubber material is pressed by the combined pressure roller 8; the operator removes the raw tire blank; the molding drum box and drum 5 move to the starting position to carry out the molding cycle of the next raw tire blank.

[0004] For the layout of the second-stage tire building machine of this type, the rubber-coated wire winding head needs to move left and right, resulting in a large floor area, and there are many servo axes, resulting in high costs. When the tread feeder 9 fits, it must wait until the rubber-coated wire winding head 7 completely gives way before it can fit, which affects production efficiency.

[0005] In summary, how to solve the problem of the large floor area of the layout of the second-stage tire building machine has become a technical problem that needs to be solved urgently by those skilled in the art. Summary of the Invention

[0006] The object of the present invention is to provide a layout structure of a second-stage tire building machine to solve the problem of the large floor area of the layout of the second-stage tire building machine.

[0007] To achieve the above object, the present invention provides a layout structure of a second-stage tire building machine, including a rubber-coated wire winding head, a building drum assembly, a building drum drive mechanism, and a tread rubber compressing assembly. The position of the rubber-coated wire winding head is fixed. The tread rubber compressing assembly is arranged side by side with the rubber-coated wire winding head. The axis of the rotating shaft of the building drum assembly is perpendicular to both the tread rubber compressing assembly and the rubber-coated wire winding head at the same time. And the building drum drive mechanism is used to drive the building drum assembly to reciprocate along the axis of the rotating shaft. When the building drum assembly moves to the first preset position, the building drum assembly cooperates with the rubber-coated wire winding head to realize the winding of the rubber-coated wire. When the building drum assembly moves to the second preset position, the building drum assembly cooperates with the tread rubber compressing assembly to realize the compressing of the tread rubber.

[0008] Preferably, it further includes a wire rubber coating device and a rubber-coated wire storage device arranged in the same row on the side of the rubber-coated wire winding head away from the building drum assembly. The wire rubber coating device is used to coat the wire with rubber and then supply it to the rubber-coated wire storage device. The rubber-coated wire storage device is used to directly supply the rubber-coated wire to the rubber-coated wire winding head at a fixed position.

[0009] Preferably, the tread rubber compressing assembly includes a tread feeder and a combined pressure roller located below the front end of the tread feeder. A feeder capable of extending above the combined pressure roller and cooperating with the building drum assembly located at the second preset position to complete the fitting of the tread rubber is provided on the tread feeder. The combined pressure roller is used to compress the tread rubber onto the tire blank installed on the building drum assembly.

[0010] Preferably, the tread rubber compressing assembly further includes a tread unwinding device arranged in the same row as the tread feeder, and the tread unwinding device is located at one end of the tread feeder away from the combined pressure roller.

[0011] Preferably, the forming drum driving mechanism includes a guide rail arranged along the moving direction of the forming drum assembly and a sliding plate slidably engaged with the guide rail, and the forming drum assembly is fixed to the sliding plate.

[0012] Preferably, a driver for driving the sliding plate to move is further provided on the sliding plate.

[0013] Preferably, the forming drum driving mechanism further includes a mounting base, and the guide rail is arranged on the mounting base.

[0014] Preferably, bolt holes for mounting lifting rings are provided at both ends of the mounting base.

[0015] Preferably, feet for fixing to the ground are further provided on both sides of the mounting base.

[0016] Preferably, the sliding plate is driven by a rotating gear and a rack engaged with the gear. The rack is fixed to the mounting base, and the gear is arranged on the sliding plate.

[0017] Compared with the content of the background art introduction, the layout structure of the above-mentioned second-stage tire forming machine includes a rubber-coated steel wire winding head, a forming drum assembly, a forming drum driving mechanism, and a tread rubber pressing assembly. The position of the rubber-coated steel wire winding head is fixed, the tread rubber pressing assembly is arranged side by side with the rubber-coated steel wire winding head, the axis of the rotating shaft of the forming drum assembly is perpendicular to both the tread rubber pressing assembly and the rubber-coated steel wire winding head at the same time, and the forming drum driving mechanism is used to drive the forming drum assembly to reciprocate along the axis direction of the rotating shaft. When the forming drum assembly moves to the first preset position, the forming drum assembly cooperates with the rubber-coated steel wire winding head to realize the winding of the rubber-coated steel wire; when the forming drum assembly moves to the second preset position, the forming drum assembly cooperates with the tread rubber pressing assembly to realize the pressing of the tread rubber. In the actual application process of this layout structure, when rubber-coated steel wire winding is required, only by driving the forming drum assembly to move to the first preset position through the forming drum driving mechanism, the cooperation between the rubber-coated steel wire winding head and the forming drum assembly can be completed, and then the rubber-coated steel wire winding operation can be performed; when tread rubber pressing is required, only by driving the forming drum assembly to move to the second preset position through the forming drum driving component, the cooperation between the tread rubber pressing assembly and the forming drum assembly can be completed, and then the tread rubber pressing operation can be realized. During the whole process, since the position of the rubber-coated steel wire winding head is fixed and does not need to move horizontally left and right, the problem of large floor area caused by the left and right movement of the rubber-coated steel wire winding head is avoided. At the same time, since the rubber-coated steel wire winding head does not need to be translated, the layout of the rubber-coated steel wire turning component and the servo axis required for translation are saved. The rubber-coated steel wire led out from the rubber-coated steel wire storage device can be directly led to the rubber-coated steel wire winding head, further reducing the floor area and saving costs at the same time.

Detailed implementation manners

[0025] The core of the present invention is to provide a layout structure of a second-stage tire building machine to solve the problem of large floor area occupied by the layout of the second-stage tire building machine.

[0026] In order to enable those skilled in the art to better understand the technical solutions provided by the present invention, the present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0027] As Figure 2 And Figure 3As shown in the figure, a layout structure of a second-stage tire building machine according to an embodiment of the present invention includes a rubber-coated steel wire winding head 13, a building drum assembly 14, a building drum driving mechanism 15, and a tread rubber compound pressing assembly 19. The position of the rubber-coated steel wire winding head 13 is fixed. The tread rubber compound pressing assembly 19 is arranged side by side with the rubber-coated steel wire winding head 13. The axis of the rotating shaft of the building drum assembly 14 is perpendicular to both the tread rubber compound pressing assembly 19 and the rubber-coated steel wire winding head 13. The building drum driving mechanism 15 is used to drive the building drum assembly 14 to reciprocate along the axis of the rotating shaft. When the building drum assembly 14 moves to the first preset position, the building drum assembly 14 cooperates with the rubber-coated steel wire winding head 13 to realize the winding of the rubber-coated steel wire. When the building drum assembly 14 moves to the second preset position, the building drum assembly 14 cooperates with the tread rubber compound pressing assembly 19 to realize the pressing of the tread rubber compound.

[0028] In the actual application process of this layout structure, when rubber-coated steel wire winding is required, only by driving the building drum assembly to move to the first preset position through the building drum driving mechanism, the cooperation between the rubber-coated steel wire winding head and the building drum assembly can be completed, and then the rubber-coated steel wire winding operation can be performed. When tread rubber compound pressing is required, only by driving the building drum assembly to move to the second preset position through the building drum driving component, the cooperation between the tread rubber compound pressing assembly and the building drum assembly can be completed, and then the tread rubber compound pressing operation can be realized. During the whole process, since the position of the rubber-coated steel wire winding head is fixed and there is no need to move horizontally left and right, the problem of large floor area caused by the left and right movement of the rubber-coated steel wire winding head is avoided. At the same time, since the rubber-coated steel wire winding head does not need to be translated, the layout of the rubber-coated steel wire turning component and the servo axis required for translation are saved. The rubber-coated steel wire exported from the rubber-coated steel wire storage device can be directly led to the rubber-coated steel wire winding head, further reducing the floor area and saving costs.

[0029] It should be noted here that those skilled in the art should be able to understand that the building drum assembly 14 generally includes a building drum body and a machine box for driving the building drum body. A rotating shaft is provided at the center of the building drum body. The tire blank is installed on the building drum body and can rotate with the rotation of the building drum body. The rubber-coated steel wire winding head 3 is used to wind the rubber-coated steel wire onto the tire blank installed on the building drum body. The tread rubber compound pressing assembly 19 is used to perform the pressing operation of the tread rubber compound on the tire blank on the building drum body, and generally includes a tread feeding rack 17 and a combined pressing roller 16. Among them, the tread feeding rack 17 is used for the fixed-length cutting of the tread rubber compound and transports it to the position where it fits the surface of the tire blank on the building drum body. The combined pressing roller 16 is used to press the tread rubber compound onto the tire blank.

[0030] In some specific embodiments, the second-stage tire building machine generally further includes a wire rubber coating device 11 and a rubber-coated wire storage device 12 arranged in the same row on the side of the rubber-coated wire winding head 13 away from the building drum assembly 14. The wire rubber coating device 11 is used to supply the rubber-coated wire to the rubber-coated wire storage device 12 after rubber coating; the rubber-coated wire storage device 12 is used to directly supply the rubber-coated wire to the rubber-coated wire winding head 13 at a fixed position. By designing the wire rubber coating device 11, the rubber-coated wire storage device 12 and the building drum assembly 14 into a structure arranged in the same row in sequence, the layout space of the whole machine can be further reduced, and it is convenient for the rubber-coated wire storage device to directly supply the rubber-coated wire to the rubber-coated wire winding head.

[0031] As should be known to those skilled in the art, the tread rubber pressing assembly 19 generally includes a tread feeding rack 17 and a combined pressing roller 16. In some specific embodiments, it is preferably to design the combined pressing roller 16 below the front end of the tread feeding rack 17, and a feeder capable of extending above the combined pressing roller 16 and cooperating with the building drum assembly 14 located at the second preset position is provided on the tread feeding rack 17 to complete the fitting of the tread rubber; the combined pressing roller 16 is used to press the tread rubber onto the tire blank installed on the building drum assembly 14. Through the above layout structure, the integration degree of the combined pressing roller 16 and the tread feeding rack 17 is higher, which is more conducive to reducing the floor area of the whole machine.

[0032] It should be noted that the above-mentioned tread rubber pressing assembly 19 generally further includes a tread unwinding device 18. In the present invention, the tread unwinding device 18 is designed to be arranged in the same row as the tread feeding rack 17, and the tread unwinding device 18 is located at one end of the tread feeding rack 17 away from the combined pressing roller 16. In this way, each mechanism of the entire tread rubber pressing assembly 19 is located on the same row of workstations, which is more conducive to reducing the occupied space of the whole machine.

[0033] In some more specific embodiments, the specific structure of the above-mentioned building drum driving mechanism 15 may include a guide rail 151 arranged along the moving direction of the building drum assembly 14 and a sliding plate 152 slidably matched with the guide rail 151, and the building drum assembly 14 is fixed on the sliding plate 152. The horizontal translation movement of the building drum assembly is realized through the above structure of the guide rail and the sliding plate. Of course, it can be understood that the above-mentioned cooperation mode of the guide rail and the sliding plate is only a preferred example of the linear translation movement structure in the embodiments of the present invention. In the actual application process, other linear movement structure forms commonly used by those skilled in the art can also be adopted, such as the structure form of a groove and a slider, etc.

[0034] In addition, it should be noted that generally, a driver for driving the sliding plate 152 to move is also provided on the sliding plate 152, and the specific structure form of the driver may include a motor and a reducer.

[0035] In a further embodiment, in order to facilitate the arrangement of the forming drum drive mechanism 15, generally speaking, the forming drum drive mechanism 15 further includes a mounting base 154, and the guide rail 151 is arranged on the mounting base 154. This can facilitate the overall displacement of the forming drum drive mechanism, and the installation is more convenient and quick.

[0036] In a further embodiment, in order to facilitate the installation and displacement of the mounting base 154, bolt holes 156 for installing the lifting rings 155 are provided at both ends of the mounting base 154. By installing the lifting rings, the removal and movement of the mounting base is more convenient, and can be directly operated by tools such as overhead cranes.

[0037] It should be noted that, in order to ensure the stability of the installation position of the installation base 154, generally, feet 157 for fixing to the ground are also provided on both sides of the installation base 154. The provision of the feet makes the installation and fixing of the installation base more convenient.

[0038] In addition, it should be noted that there are various ways to drive the skateboard along the guide rail. For example, the skateboard 152 can be driven by a rotating gear and a rack 158 that cooperates with the gear. The rack 158 is fixed on the mounting base 154, and the gear is set on the skateboard 152. It can also be other linear driving methods commonly used by technical personnel in this field, such as directly driving the skateboard to move along the guide rail through a cylinder or an oil cylinder, or a motor driving a screw mechanism, etc.

[0039] In order for those skilled in the art to better understand the technical solution provided by the present invention, the specific process flow of the second stage tire molding machine is described below:

[0040] Step 1: The steel wire is coated with glue by the steel wire coating device 11;

[0041] Step 2: pre-storing some of the rubber-coated steel wires through the rubber-coated steel wire storage device 12;

[0043] Step 4: The tread rubber material is guided out by the tread guiding device 18, and the tread rubber material is fixed in length and cut through the tread feeding rack 17;

[0044] Step 5: The operator places the cylindrical tire blank produced by the first stage of the molding machine on the molding drum body on the molding drum assembly 14 of the second stage molding machine, and pre-shapes the tire blank by inflating the tire blank and propping it up with tiles;

[0045] Step 6: The rubber-coated wire winding head 13 winds the rubber-coated wire onto the pre-shaped tire blank. After the winding of the rubber-coated wire is completed, the forming drum driving mechanism 15 drives the forming drum assembly 14 to move to the tread fitting station (the station facing the tread rubber pressing assembly 19).

[0046] Step 7: The tread feeder of the tread supply rack 17 extends the feeder to perform and complete the fitting of the tread rubber to the tire blank.

[0047] Step 8: The combination pressure roller 16 is used to complete the pressing of the tread rubber to form a green tire blank.

[0048] Step 9: The operator removes the green tire blank.

[0049] Step 10: Drive the forming drum assembly to move to the starting position to perform the forming cycle of the next green tire blank.
