Description

TECHNICAL FIELD

[0001] The application relates to the field of tire processing technology, in particular to a carcass continuous feeding mechanism of a semi-steel secondary method tire building machine. BACKGROUND

[0002] A tire building machine is a key equipment for manufacturing tires, and a device process is to gradually assemble various rubber parts (such as a tread, a sidewall, a ply, a steel wire ring and the like) into an unvulcanized tire blank according to the structural design requirements of the tire. The semi-steel secondary method tire building machine is a kind of tire building machine, and is a core equipment specially used for manufacturing semi-steel radial tires, and adopts a secondary method forming process.

[0003] A Chinese utility model patent with the authorized announcement number CN208714536U: a belt feeding device and a tire building machine, discloses that a first feeding station and a second feeding station are sequentially arranged along a belt feeding direction, feeding cars are arranged below the first feeding station and the second feeding station respectively, or a first feeding car is located on one side of the first feeding station, and a second feeding car is arranged on one side of the second feeding station and below the first feeding station; a centering device is arranged on one side of the first feeding station and / or the second feeding station, the centering device clamps both sides of the belt to fix and support the belt, and the technical effect of avoiding the belt from being twisted and adhered due to its own reasons is achieved.

[0004] A Chinese utility model patent with the authorized announcement number CN208682192U: a belt positioning device, a belt feeding device and a tire building machine, discloses that the device comprises a support frame, a shell fixed on the support frame, a driving device and a magnetic generating device, the magnetic generating device is arranged in the shell; the driving device can drive the magnetic generating device to move to selectively position the belt; the technical effect of avoiding the belt from being twisted or adhered is achieved by using the magnetic generating device to attract the belt.

[0005] The above-mentioned patents respectively use clamping and magnetic attraction to avoid the belt from being twisted or adhered, and it can be seen that the prior art solutions all need to make the belt directly contact with solid parts, so as to solve the technical problem of avoiding the belt from being twisted or adhered, and in the process of contacting with the solid parts, the belt is prone to wear, which causes the risk of product quality decline, and the prior art cannot solve the technical problem of avoiding the belt from being twisted or adhered during conveying or shutdown and avoiding the wear of the surface of the belt, so the field urgently needs the carcass continuous feeding mechanism of the semi-steel secondary method tire building machine to solve the problems existing in the prior art. SUMMARY

[0006] The purpose of the present application is to provide a carcass continuous feeding mechanism of a semi-steel secondary method tire building machine technical solution to solve the problems existing in the prior art.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] The continuous carcass feeding mechanism of a semi-steel secondary tire building machine includes two vertically arranged flat plates, each parallel to the other. Air holes are horizontally formed through the plates in a rectangular array. The air holes include an integrally formed ventilation area and an air guide area. The two flat plates face each other near one end of the air guide area. The spacing between the two flat plates is 1.3-1.7 times the thickness of the belt material, which can improve the stress stability of the belt material.

[0009] The upper end of the opening of the wind guide area is rounded, so that the wind ejected from the wind guide area has a tendency to be directed vertically upward or obliquely upward;

[0010] The two flat plates are sealed and fixed with a sealed shell at one end away from each other, and the sealed shell is connected to an external air supply device;

[0011] The top end of the sealing shell is fixedly connected to the shell of the external belt layer feeding rack.

[0012] As a preferred solution, the sealed housing includes an end plate and a side plate sealed and fixed to an edge of the end plate, and the side plate is sealed and fixed to the straight plate.

[0013] As a preferred solution, the sealed shell also includes a connecting shell that is sealed and fixed on the end of the end plate away from the straight plate. The connecting shell is sealed and fixed on the end away from the end plate with a connecting pipe. The straight plate and the sealed shell together form a sealed space that can only be connected to the outside world through the air hole and the connecting pipe. The connecting pipe is connected to the external air supply equipment. As a preferred solution, the external air supply equipment is an air pump.

[0014] As a preferred solution, in the horizontal direction, one end portion of the two straight plates are fixedly connected by a stabilizing bar, which can enhance the stability of the straight plates. The top end of one end plate is fixedly connected to the shell of the external belt layer feeding rack through a connecting piece, which simplifies the fixing scheme of this mechanism and the shell of the external belt layer feeding rack and enhances practicality.

[0015] As a preferred solution, in the horizontal direction, the two straight plates are connected and fixed at one end away from the stabilizing bar by a stabilizing plate. The stabilizing plate is an easily disassembled structure. As a preferred solution, one end of the stabilizing plate is connected to a straight plate rotating shaft, and the other end of the stabilizing plate is connected to another straight plate bolt.

[0016] As a preferred solution, an arc-shaped guide plate is fixedly installed below the straight plate, and the bottom of the guide plate is bent toward the end plate.

[0017] As a preferred solution, the vertical span of the rounded corners is 5-10 mm.

[0018] As a preferred solution, the distance between the two straight plates is times the thickness of the belt layer raw material.

[0019] As a preferred solution, the shape, position and spacing of the air holes in the array on the two flat plates are the same, presenting a mirror image structure, which can improve the stress stability of the belt layer material and reduce the production cost of the flat plates.

[0020] As a preferred solution, the spacing between adjacent air holes is 10-20 mm.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The present invention is designed such that both sides of the belt material are spatially limited by two flat plates, which can prevent the belt material from swinging or twisting, thereby achieving the technical effect of preventing the U-shaped area from being kinked or stuck.

[0023] 2. The present invention can spatially limit the belt material to avoid swinging or twisting, and can also prevent friction between the belt material and the flat plate during transportation or static state, thereby preventing surface damage.

[0024] 3. When the present invention is in use, the center of the belt layer material is vertically aligned with the center of the straight air hole. When the belt layer material produces a lateral swing parallel to the surface of the flat plate, the belt layer material and the straight air hole lose the alignment effect. The deflected air holes located on both sides of the straight air hole can directly blow to the surface of the belt layer material, and the number of deflected air holes is different, so that the surface of the belt layer material produces a lateral force difference when being blown. The deflected air holes can push the center of the belt layer material laterally towards the trend of aligning with the straight air holes, so that the belt layer material can always keep the center aligned with the straight air holes.

[0025] 4. In the present invention, when the external belt layer feeding rack is stopped and the belt layer raw material is not continued to be conveyed, or in the gap between each conveyance of the belt layer raw material, the existing technology needs to use an anti-backflow pressure roller to prevent the belt layer raw material from sliding in the opposite direction under the action of gravity to ensure the continuity of the tire production process. The present scheme always provides a contactless upward thrust to the belt layer raw material in the belt layer raw material conveying gap, which can reduce the pressure required by the anti-backflow pressure roller to limit the belt layer raw material, avoid the anti-backflow pressure roller causing pressure deformation inside the belt layer raw material, avoid pressure wear on the surface of the belt layer raw material, and help improve the quality of tire production.

[0026] 5. The present invention uses air film limiting as the core solution. Compared with the existing technology that uses magnetic attraction and can only limit the belt layer materials filled with steel wire, this solution can be applied to belt layer materials filled with steel wire, aramid, and glass fiber at the same time, and has a wide applicability.

DETAILED DESCRIPTION

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] Example 1: Figures 1-6 , Figures 8-10 As shown, the present invention provides a technical solution for a continuous carcass feeding mechanism of a semi-steel secondary tire building machine, comprising two vertically arranged flat plates 101, the two flat plates 101 being parallel to each other, and having air holes 102 extending horizontally through the flat plates 101 in a rectangular array. The air holes 102 include an integrally formed ventilation area 103 and an air guide area 104. The two flat plates 101 face each other at one end near the air guide area 104, and the spacing between the two flat plates 101 is 1.5 times the thickness of the belt layer material 501, thereby improving the stress stability of the belt layer material 501.

[0040] The upper end of the opening of the wind guide area 104 is rounded, so that the wind ejected from the wind guide area 104 has a tendency to be directed vertically upward;

[0041] The two flat plates 101 are sealed and fixedly connected to a sealed housing at one end away from each other, and the sealed housing is connected to an external air supply device;

[0042] The top end of the sealing shell is fixedly connected to the shell of the external belt layer feeding rack.

[0043] The sealed housing includes an end plate 201 and a side plate 202 sealed and fixed to the edge of the end plate 201 . The side plate 202 is sealed and fixed to the flat plate 101 .

[0044] The sealed shell also includes a connecting shell 203 sealed and fixed on the end of the end plate 201 away from the straight plate 101. The connecting shell 203 is sealed and fixed on the end away from the end plate 201 with a connecting pipe 204. The straight plate 101 and the sealed shell together form a sealed space that can only be connected to the outside world through the air hole 102 and the connecting pipe 204. The connecting pipe 204 is connected to the air pump.

[0045] In the horizontal direction, one end portion of the two straight plates 101 is fixedly connected by a stabilizing bar 301, which can enhance the stability of the straight plates 101. The top end of an end plate 201 is fixedly connected to the shell of the external belt layer feeding rack through a connecting piece 302, which simplifies the fixing scheme of this mechanism and the shell of the external belt layer feeding rack and enhances practicality.

[0046] In the horizontal direction, the ends of the two straight plates 101 away from the stabilizing bar 301 are connected and fixed by a stabilizing piece 303 . One end of the stabilizing piece 303 is connected to the rotating shaft of one straight plate 101 , and the other end of the stabilizing piece 303 is bolted to the other straight plate 101 .

[0047] An arc-shaped guide plate 401 is fixedly installed below the flat plate 101 , and the bottom of the guide plate 401 is bent toward the end plate 201 .

[0048] The vertical span of the fillet is 8 mm.

[0049] On the two flat plates 101 , the arrayed air holes 102 have the same shape, position, and spacing, presenting a mirror image structure, which can improve the stress stability of the belt layer material 501 and reduce the production cost of the flat plates 101 .

[0050] The distance between adjacent air holes 102 is 15 mm.

[0051] Working principle: During the process of conveying the belt layer raw material 501 from the feeding vehicle to the belt layer feeding rack, the belt layer raw material 501 itself is suspended to form a U-shaped area between the discharge end of the feeding vehicle and the feeding end of the belt layer feeding rack; in order to avoid the U-shaped area from twisting or adhesion, the feeding mechanism of the present invention is installed in the vertical area of ​​the U-shaped area close to one end of the belt layer feeding rack, and the straight plate 101 is in a vertical state. The sheet-like belt layer raw material 501 passes through the gap between the two straight plates 101 from bottom to top, and then enters the interior of the belt layer feeding rack to complete the subsequent belt layer bonding process; at this point, the two sides of the belt layer raw material 501 are spatially limited by the two straight plates 101, which can prevent the belt layer raw material 501 from swinging or twisting, thereby achieving the technical effect of avoiding twisting or adhesion in the U-shaped area.

[0052] No matter the belt layer raw material 501 is in the process of being transported when the machine is turned on or is kept stationary when the machine is stopped, the air pump continuously supplies air at a steady pressure into the sealed shell. After the air flows through the ventilation area 103, it flows out upward under the guidance of the wind guide area 104. The outflowing air is blocked by the belt layer raw material 501, and a flowing air film is formed on the side wall surfaces of the belt layer raw material 501 close to the flat plate 101, so that the belt layer raw material 501 cannot effectively contact the flat plate 101 for a long time. Only when the component or the air pump pressure fails and the pressure difference on both sides of the belt layer raw material 501 fluctuates and becomes unbalanced, the belt layer raw material 501 can lightly touch the surface of the flat plate 101. At this point, the scheme can spatially limit the belt layer raw material 501 to avoid swinging or twisting, and can also avoid friction between the belt layer raw material 501 and the flat plate 101 during transportation or static state to cause surface damage.

[0053] Example 2, based on the technical solution of Example 1, Figure 7As shown, the openings of a row of air guide areas 104 located in the center are kept in a vertical state, which are straight air holes 102a; the upper parts of the openings of the air guide areas 104 on both sides are inclined toward the straight air holes 102a, which are deflected air holes 102b; the number of rows of straight air holes 102a can be designed according to the width of the belt layer material 501. For the belt layer material 501 with a large width, a straight plate 101 with three rows of straight air holes 102a is used. For the belt layer material 501 with a small width, a straight plate 101 with one row of straight air holes 102a is used. With this solution, when in use, the center of the belt layer material 501 and the center of the straight air holes 102a are aligned. The center of the belt layer material 501 is vertically aligned. When the belt layer material 501 produces a lateral swing parallel to the surface of the flat plate 101, the belt layer material 501 and the straight air hole 102a lose the alignment effect. The deflected air holes 102b located on both sides of the straight air hole 102a can directly blow to the surface of the belt layer material 501. There is a difference in the number of deflected air holes 102b, which makes the surface of the belt layer material 501 have a lateral force difference when being blown. The deflected air holes 102b can push the center of the belt layer material 501 to align with the straight air holes 102a laterally, so that the belt layer material 501 can always keep the center aligned with the straight air holes 102a.

Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein.
