Description

Technical Field

[0001] The invention relates to the technical field of rubber material conveying, in particular to a central belt drum case with a mis-sticking function. Background Art

[0002] With the development of automobile industry technology, the demand for tires in the market has become increasingly diversified, so the specifications of tires are also different. As a key equipment in tire manufacturing, the belting drum can transport and adhere the rubber used to produce tires to the drum surface during the movement process, ensuring the smooth progress of the tire production process.

[0003] However, most of the belt drum machines currently used for producing tires on the market have limitations. They only have radial movement function. This single movement mode can only deliver the rubber to the middle position of the belt drum, which fixes the width of the rubber and limits the production range of tires. The same machine can only produce semi-finished rubber that customers already have during the production process, and cannot produce tires of special order specifications at the same time, resulting in a narrow range of production specifications and difficulty in meeting the market's increasingly diversified demands. Summary of the invention

[0004] In view of this, the purpose of the present invention is to provide a central belt drum casing with a mis-sticking function, which has the radial movement function and can also move axially. It can not only transport and stick the rubber to the middle position of the belt drum according to the tire specifications, but also enable the rubber of the tire to be offset and mis-sticked on the belt drum, even if the width of the rubber is widened on the basis of the original width.

[0005] The embodiment of the present invention provides a central belt drum chassis with misalignment function, comprising: Base, bottom plate, box, belt drum, misaligned cylinder, center positioning bearing, left and right positioning screws, center positioning cylinder, V-shaped limit block; The base is provided with the bottom plate, the box body is installed on the bottom plate, and the belt drum is provided on the upper part of the box body; The bottom plate is also equipped with the misaligned cylinder, the piston rod of which is connected to one side of the box body, and the other side of the box body is provided with a center positioning bearing; A fixing seat is provided at the rear side of the central positioning bearing, and the fixing seat is mounted on the bottom plate. Two left and right positioning screws are symmetrically provided on the left and right sides of the fixing seat, respectively, and the left and right positioning screws can adjust the length of the fixing seat protruding therefrom. The center positioning cylinder is also installed on the base plate, and a V-shaped limit block is provided at the end of the piston rod of the center positioning cylinder; when the piston rod of the center positioning cylinder is extended, the center positioning cylinder can slide in contact with the center positioning bearing through the V-shaped limit block; when the piston rod of the center positioning cylinder is retracted, the misaligned cylinder can be extended or retracted, so that the box body can move axially on the base plate.

[0006] Preferably, a moving power is also installed on the base, and the moving power is connected to the bottom plate through a belt transmission mechanism, and can drive the bottom plate to move radially.

[0007] Preferably, the motor of the mobile power is connected to the pulley of the first synchronous belt, and the first synchronous belt is fixedly connected to the base plate via a clamping plate.

[0008] Preferably, a radial guide rail slider is also installed on the base, and the bottom plate is arranged on the radial guide rail slider.

[0009] Preferably, a hot knife heater and a separation and combination pressure roller are further provided on the box body, and the hot knife heater and the separation and combination pressure roller are respectively arranged on both sides of the belt drum.

[0010] Preferably, an axial guide rail slider is also installed on the base plate, and the box body is arranged on the axial guide rail slider.

[0011] The embodiments of the present invention bring the following beneficial effects: Compared with the prior art, the present invention enables the belt drum to move axially while having radial movement function. Through the axial movement of the belt drum casing, not only can the rubber be transported and bonded to the middle position of the belt drum according to the tire specifications, but the rubber can also be offset and mis-bonded on the belt drum to achieve the effect of increasing the width of the rubber. Without increasing the types of semi-finished rubber products in the previous order, tires of different specifications can be produced, thereby meeting the market demand for small batch orders of tires with special specifications.

[0018] To facilitate understanding of this embodiment, Figure 1 The central belt drum chassis with mis-sticking function disclosed in an embodiment of the present invention is introduced in detail. Example 1

[0019] Combination Figures 1 to 6The chassis with a center belt drum having a mis-sticking function comprises: a base 5, a bottom plate 8, a housing 4, a belt drum 2, a mis-sticking cylinder 13, a center positioning bearing 14, left and right positioning screws 15, a center positioning cylinder 16, and a V-shaped limit block 17.

[0020] A bottom plate 8 is provided on the base 5 , a box body 4 is mounted on the bottom plate 8 , and a belt tension drum 2 is provided on the box body 4 .

[0021] In this embodiment, a rotating power 10 is also installed on the box body 4, a belt-belting drum 2 is provided at the front of the box body 4, a main shaft 12 is provided inside the belt-belting drum 2, and a pneumatic rotating joint 11 is provided on the main shaft 12; The rotary power 10 drives the belt drum 2 to rotate around the central axis through the second synchronous belt, and the pneumatic rotary joint 11 is used to enable the air pipe fixed to the pneumatic rotary joint 11 to rotate along with the belt drum 2 .

[0022] Preferably, combined Figure 2 A moving power 6 is also installed on the base 5. The moving power 6 is connected to the bottom plate 8 through a belt transmission mechanism and can drive the bottom plate 8 to move radially.

[0023] In this embodiment, the moving power 6 and the belt transmission mechanism are both installed on the left side inside the base 5 ; the direction of radial movement is perpendicular to the central axis direction of the belt drum 2 .

[0024] Furthermore, the motor of the mobile power 6 is connected to the pulley of the first synchronous belt, and the first synchronous belt is fixedly connected to the base plate 8 via a clamping plate.

[0025] Preferably, combined Figure 2 A radial guide rail slider 7 is also installed on the base 5, and a bottom plate 8 is arranged on the radial guide rail slider 7.

[0026] When the moving power 6 drives the bottom plate 8 to move radially, the bottom plate 8 can slide radially on the guide rail of the radial guide rail slider 7 through the slider of the radial guide rail slider 7.

[0027] Preferably, combined Figure 1 , Figure 3 A hot knife heater 1 and a separation and combination pressure roller 3 are also provided on the box body 4. The hot knife heater 1 and the separation and combination pressure roller 3 are respectively arranged on both sides of the belt drum 2.

[0028] In this embodiment, the hot knife heater 1 and the separation and combination pressure roller 3 are both arranged at the front of the box 4. The separation and combination pressure roller 3 has a push-pull structure, which can push the separation and combination pressure roller 3 to press the rubber material attached to the belt drum 2.

[0029] Combination Figure 1 , Figure 4A misaligned cylinder 13 is also installed on the bottom plate 8, and a piston rod of the misaligned cylinder 13 is connected to one side of the box body 4, and a center positioning bearing 14 is provided on the other side of the box body 4.

[0030] In this embodiment, the misaligned cylinder 13 is located in the middle of the rear side of the box body 4, the piston rod of the misaligned cylinder 13 is connected to the left side of the rear part of the box body 4, and a center positioning bearing 14 is provided on the right side of the rear part of the box body 4.

[0031] A fixing seat is provided at the rear side of the center positioning bearing 14, and the fixing seat is installed on the bottom plate 8. Two left and right positioning screws 15 are symmetrically provided on the left and right sides of the fixing seat, and the left and right positioning screws 15 can adjust the length of the fixing seat.

[0032] Combination Figure 1 , Figure 4 , Figure 5 , Figure 6 A center positioning cylinder 16 is also installed on the bottom plate 8, and a V-shaped limit block 17 is provided at the end of the piston rod of the center positioning cylinder 16; when the piston rod of the center positioning cylinder 16 is extended, the center positioning cylinder 16 can slide in contact with the center positioning bearing 14 through the V-shaped limit block 17; when the piston rod of the center positioning cylinder 16 is retracted, the misaligned cylinder 13 can be extended or retracted, so that the box body 4 can move axially on the bottom plate 8.

[0033] In this embodiment, the direction of the axial movement is parallel to the central axis direction of the belt drum 2 , that is, the direction of the axial movement is perpendicular to the direction of the radial movement.

[0034] In this embodiment, when the piston rod of the center positioning cylinder 16 extends forward, the center positioning cylinder 16 can make sliding contact with the outer ring of the center positioning bearing 14 through the end of the V-shaped limit block 17, so that the center positioning bearing 14 offset to the left or right gradually moves toward the center position until the center positioning bearing 14 is guided to the middle position, and then the box body 4 also moves to the middle position following the center positioning bearing 14. At this time, the belt drum 2 on the box body 4 also moves to the middle position; When the belt drum 2 is in the middle position, the belt drum 2 can adhere the hot knife heater 1 and the rubber material cut by the hot knife to the middle of the belt drum surface.

[0035] In this embodiment, when the piston rod of the center positioning cylinder 16 retracts backward, the misaligned cylinder 13 can extend to the left or retract to the right, thereby driving the box body 4 to move axially, and the center positioning bearing 14 simultaneously follows the box body 4 to move axially on the bottom plate 8. Since the rear part of the center positioning bearing 14 is provided with a fixed seat through which two left and right positioning screws 15 with adjustable lengths are passed, and the left and right positioning screws 15 can limit the axial movement distance of the center positioning bearing 14, the axial movement distance of the box body 4 and the belt tension drum 2 on the box body 4 is also limited accordingly; When the belt drum 2 moves axially, the belt drum 2 can misalign the conveyed rubber material to the belt drum surface, so that the position of the rubber material is offset to the middle of the belt drum surface.

[0036] Preferably, an axial guide rail slider 9 is also installed on the bottom plate 8 , and the box body 4 is arranged on the axial guide rail slider 9 .

[0037] When the misalignment cylinder 13 is extended or retracted, the box body 4 can slide axially on the guide rail of the axial guide rail slider 9 through the slider of the axial guide rail slider 9.

[0038] The working principle of the central belt drum case with misplaced function in this embodiment includes the following steps: When the chassis is moving radially, the moving power 6 uses the first synchronous belt of the belt transmission mechanism to drive the bottom plate 8 to move radially on the guide rail through the slider of the radial guide rail slider 7, thereby driving the belt drum 2 on the box body 4 to move to a specified position. The function of the radial movement of the chassis is to enable the belt drum 2 to avoid the transfer ring and prevent collision between devices.

[0039] When the chassis is implemented to move axially, the piston rod of the center positioning cylinder 16 is first retracted, and the length of the left and right positioning screws 15 extending inside the fixing seat is adjusted according to the width of the rubber material, and then the piston rod of the misaligned cylinder 13 is extended or retracted. At this time, the box body 4 is driven by the misaligned cylinder 13 to move axially on the base plate 8 through the slider of the axial guide slider 9, thereby driving the belt drum 2 to move axially, and the center positioning bearing 14 also follows the box body 4 to move axially synchronously under the restriction of the two left and right positioning screws 15.

[0040] When the misaligned cylinder 13 is depressurized, the center positioning cylinder 16 extends, driving the V-shaped limit block to limit the center limit bearing 14, and the center positioning bearing 14 moves to the middle position. At this time, the box body 4 moves to the middle position together with the center positioning bearing 14.

[0041] When the belt drum 2 moves axially driven by the box 4 or moves to the middle position driven by the box 4 , the belt drum 2 bonds the conveyed rubber material and presses the bonded rubber material through the separation and combination roller 3 .
