Description

Technical Field

[0001] The present invention relates to the technical field of rubber conveying, and particularly to a misalignment function middle-position belt drum box. Background Art

[0002] With the development of automotive industry technology, the market demand for tires is increasingly diversified, so the specifications of tires are also different. As a key device in tire manufacturing, the belt drum can convey and bond the rubber compound used for tire production to the drum surface of the belt drum during movement, ensuring the smooth progress of the tire production process.

[0003] However, the belt drum boxes for most tire production on the market currently have limitations. They only have the radial movement function. This single movement method can only convey and bond the rubber compound to the middle position of the belt drum, that is, it fixes the width of the rubber compound, limits the tire production range, and enables the same box to only produce the semi-finished rubber compound that the customer already has during the production process, and cannot produce tires with special order specifications at the same time, resulting in a narrow production specification range and being difficult to meet the increasing diversified market demands. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a misalignment function middle-position belt drum box, which can not only axially move while having the radial movement function, but also can convey and bond the rubber compound to the middle position of the belt drum according to the tire specifications, and can also achieve offset misalignment of the rubber compound of the tire on the belt drum, that is, widen the width of the rubber compound on the basis of the original width.

[0005] The misalignment function middle-position belt drum box provided by the embodiment of the present invention includes:

[0006] Base, bottom plate, box body, belt drum, misalignment cylinder, center positioning bearing, left and right positioning screws, center positioning cylinder, V-shaped limit block;

[0008] The misalignment cylinder is also installed on the bottom plate, the piston rod of the misalignment cylinder is connected to one side of the box body, and a center positioning bearing is provided on the other side of the box body;

[0009] A fixed seat is provided at the rear side of the center positioning bearing, the fixed seat is installed on the bottom plate, and two left and right positioning screws are symmetrically penetrated through the left and right sides of the fixed seat respectively, and the left and right positioning screws can adjust the length of their protrusion inside the fixed seat;

[0010] The center positioning cylinder is also installed on the bottom 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 extends, the center positioning cylinder can be in sliding contact with the center positioning bearing through the V-shaped limit block; when the piston rod of the center positioning cylinder retracts, the misaligned cylinder can extend or retract, enabling the box body to axially move on the bottom plate.

[0011] Preferably, a moving power is also installed on the base, and the moving power is connected to the bottom plate through a belt drive mechanism, capable of driving the bottom plate to radially move.

[0012] Preferably, the motor of the moving power is connected to the pulley of the first synchronous belt, and the first synchronous belt is fixedly connected to the bottom plate through a splint.

[0014] Preferably, a hot knife heater and a separating and combining pressure roller are also provided on the box body, and the hot knife heater and the separating and combining pressure roller are respectively arranged on both sides of the belt drum.

[0015] Preferably, an axial guide rail slider is also installed on the bottom plate, and the box body is arranged on the axial guide rail slider.

[0016] The embodiments of the present invention bring the following beneficial effects:

[0017] Compared with the prior art, the present invention enables the belt drum to have both radial movement function and axial movement. Through the axial movement of the belt drum chassis, not only can the rubber compound be conveyed and adhered to the middle position of the belt drum according to the tire specifications, but also the rubber compound can be offset and misaligned on the belt drum, achieving the effect of increasing the width of the rubber compound. Without increasing the types of pre-processed semi-finished rubber compounds, tires of different specifications can be produced, thereby meeting the market demand for small-batch orders of special-specification tires.

Specific Embodiments

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions of the present invention with reference to the drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0029] For ease of understanding of this embodiment, in combination with Figure 1 A detailed introduction is given to the misaligned sticker function mid-mounted belt drum chassis disclosed in the embodiments of the present invention. Example 1

[0030] Combined with Figures 1 to 6 , the mislabeling function center belt drum chassis includes: a base 5, a bottom plate 8, a box body 4, a belt drum 2, a mislabeling cylinder 13, a central positioning bearing 14, left and right positioning screws 15, a central positioning cylinder 16, and a V-shaped limit block 17.

[0031] A bottom plate 8 is provided on the base 5, and a box body 4 is installed on the bottom plate 8, and a belt drum 2 is provided on the box body 4.

[0032] In this embodiment, a rotary power 10 is further installed on the box body 4. A belt drum 2 is provided at the front of the box body 4. A main shaft 12 is provided inside the belt drum 2, and a pneumatic rotary joint 11 is provided on the main shaft 12;

[0033] Among them, the rotary power 10 drives the belt drum 2 to rotate around the central axis through a 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.

[0034] Preferably, combined with Figure 2 , a moving power 6 is further 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.

[0035] In this embodiment, both the moving power 6 and the belt transmission mechanism are installed on the left side inside the base 5; the radial moving direction is perpendicular to the central axis direction of the belt drum 2.

[0036] Furthermore, the motor of the moving power 6 is connected to the pulley of the first synchronous belt, and the first synchronous belt is fixedly connected to the bottom plate 8 through a splint.

[0037] Preferably, combined with Figure 2 , a radial guide rail slider 7 is further installed on the base 5, and the bottom plate 8 is arranged on the radial guide rail slider 7.

[0038] Among them, when the moving power 6 drives the bottom plate 8 to move radially, the bottom plate 8 can radially slide on the guide rail of the radial guide rail slider 7 through the slider of the radial guide rail slider 7.

[0039] Preferably, combined with Figure 1 、 Figure 3 , a hot knife heater 1 and a split and combined pressure roller 3 are further provided on the box body 4. The hot knife heater 1 and the split and combined pressure roller 3 are respectively arranged on both sides of the belt drum 2.

[0040] In this embodiment, both the hot knife heater 1 and the split and combined pressure roller 3 are arranged at the front of the box body 4. The split and combined pressure roller 3 has a push-pull structure and can push the split and combined pressure roller 3 to roll and fit the rubber material on the belt drum 2.

[0041] Combined withFigure 1 , Figure 4 , a mislabeling cylinder 13 is further installed on the bottom plate 8. The piston rod of the mislabeling 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.

[0042] In this embodiment, the mislabeling cylinder 13 is located at the middle position at the rear side of the box body 4. The piston rod of the mislabeling 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.

[0043] A fixed seat is provided at the rear side of the center positioning bearing 14. The fixed seat is installed on the bottom plate 8. Two left and right positioning screws 15 are symmetrically inserted through the left and right sides of the fixed seat respectively, and the left and right positioning screws 15 can adjust the length of their protrusion inside the fixed seat.

[0044] Combined with Figure 1 , Figure 4 , Figure 5 , Figure 6 , a center positioning cylinder 16 is further installed on the bottom plate 8. 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 extends, the center positioning cylinder 16 can be in sliding contact with the center positioning bearing 14 through the V-shaped limit block 17; when the piston rod of the center positioning cylinder 16 retracts, the mislabeling cylinder 13 can extend or retract, so that the box body 4 can axially move on the bottom plate 8.

[0045] 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.

[0046] In this embodiment, when the piston rod of the center positioning cylinder 16 extends forward, the center positioning cylinder 16 can be in 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 towards 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;

[0047] Among them, when the belt drum 2 is in the middle position, the belt drum 2 can attach the rubber material processed and cut by the hot knife heater 1 and the hot knife to the middle of the belt drum surface.

[0048] In this embodiment, when the piston rod of the central positioning cylinder 16 retracts backward, the misalignment cylinder 13 can extend leftward or retract rightward, thereby driving the box body 4 to move axially. The central positioning bearing 14 simultaneously follows the box body 4 to move axially on the bottom plate 8. Since the fixing seat provided at the rear of the central positioning bearing 14 is penetrated by two left and right positioning screws 15 with adjustable lengths, and the left and right positioning screws 15 can limit the axial movement distance of the central positioning bearing 14, the axial movement distance of the box body 4 and the belt drum 2 on the box body 4 is also limited accordingly.

[0049] Among them, when the belt drum 2 moves axially, the belt drum 2 can misalign the conveyed rubber material to the drum surface of the belt drum, so that the position of the rubber material is offset to the middle of the drum surface of the belt drum.

[0050] Preferably, an axial guide rail slider 9 is further installed on the bottom plate 8, and the box body 4 is arranged on the axial guide rail slider 9.

[0051] Among them, when the misalignment cylinder 13 extends or retracts, the box body 4 can axially slide and move on the guide rail of the axial guide rail slider 9 through the slider of the axial guide rail slider 9.

[0052] The working principle of the misalignment function center-mounted belt drum machine box in this embodiment includes the following steps:

[0053] When the machine box performs radial movement, 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 the specified position. The function of the radial movement of the machine box is to enable the belt drum 2 to avoid the transfer ring and prevent collisions between devices.

[0054] When the machine box performs axial movement, first retract the piston rod of the central positioning cylinder 16, adjust the length of the left and right positioning screws 15 extending inside the fixing seat according to the width of the rubber material, and then extend or retract the piston rod of the misalignment cylinder 13. At this time, the box body 4 is driven by the misalignment cylinder 13 to axially move on the bottom plate 8 through the slider of the axial guide rail slider 9, thereby driving the belt drum 2 to be able to move axially, and the central positioning bearing 14 also follows the box body 4 to move axially synchronously under the limitation of the two left and right positioning screws 15.

[0055] When the misalignment cylinder 13 is depressurized, extend the central positioning cylinder 16 to drive the V-shaped limit block to limit the central limit bearing 14 and move the central positioning bearing 14 to the middle position. At this time, the box body 4 moves to the middle position together with the central positioning bearing 14.

[0056] Among them, when the belt drum 2 moves axially driven by the box body 4 or moves to the middle position driven by the box body 4, the belt drum 2 fits the conveyed rubber material and rolls the fitted rubber material through the split and combined pressure roller 3.
