Description

Technical Field

[0001] This invention relates to the field of tire inspection technology, and in particular to an awl for puncturing tire lining. Background Technology

[0002] Currently, tire forming machines are devices used in the tire production process to assemble semi-finished components, including the tread, sidewall, carcass, and inner liner, into a tire blank. The inner liner is the first semi-finished component, and it is joined together with or without sealing adhesive before being combined with the carcass and other components.

[0003] Currently, in the semi-finished component molding process, each component has size and weight standards, but there are problems such as deviations from the upper and lower limits; each component needs to be placed in the designed position, but the cursor light cannot be completely implemented according to the standard; each component needs to have appropriate adhesion, but sometimes fluctuations in raw materials, equipment, processes, and the length of time the component is left to stand can lead to a decrease in adhesion; during the component bonding process, pressure rollers are needed to release air, and the pressure, shape, and position of the pressure rollers affect the bonding quality.

[0004] The aforementioned fluctuations in component size and weight, component positioning, component adhesion, and the pressure, shape, and position of the pressure rollers can all lead to air bubbles in the components. To avoid air bubbles in the tire liner after vulcanization, the tire carcass's liner is perforated. The perforation must not penetrate the tire carcass or puncture the tire completely. However, the depth of the awl used for perforation is not adjustable, making it difficult to control the perforation depth and easily resulting in punctures that penetrate the tire, causing air leaks, affecting tire quality, and in severe cases, causing a blowout. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an awl for piercing with an inner lining whose length can be changed according to actual conditions.

[0006] To solve the above-mentioned technical problems, the present invention provides an awl for puncturing lining, comprising: an awl handle and an awl head;

[0007] Preferably, the cone handle includes a gripping portion and a connecting portion, and the cone handle is connected to the cone head through the connecting portion;

[0008] More preferably, the cone includes a cone body and a support portion, one end of the support portion is fixedly connected to the connecting portion, and the other end is connected to the cone body through the driving device.

[0009] Preferably, the connecting part is a housing, with an opening on one side, one end of the connecting part being threadedly connected to the gripping part, and the other end being connected to the cone head;

[0010] More preferably, the gripping part includes a cover end and a protective sleeve, one end of which is connected to the cone head by a thread, and the other end is fixedly connected to the cover end.

[0011] Preferably, a driving device is provided inside the connecting part, and the driving device is fixedly connected to the cone head.

[0012] More preferably, the driving device includes a driving rod, a driven rod, and a connecting rod; the driving rod is disposed inside the bearing part and is connected to the driven rod through the connecting rod, and the bearing part is connected to the cone head body through the driven rod.

[0013] More preferably, one end of the active rod is provided with a through hole, and a first fixed rod is fixedly connected inside the through hole. The length of the first fixed rod is greater than the width of the active rod. One end of the connecting rod is connected to the first fixed rod. When the connecting rod is only connected to the first fixed rod, the connecting rod can rotate around the first fixed rod.

[0014] One end of the driven rod is also provided with a through hole, and a second fixed rod is fixedly connected inside the through hole. The length of the second fixed rod is greater than the width of the driven rod. The other end of the connecting rod is connected to the second fixed rod. When the connecting rod is only connected to the second fixed rod, the connecting rod can rotate around the second fixed rod.

[0015] Preferably, the bearing part has a first limiting groove and a second limiting groove inside, and a limiting post is provided in the limiting groove. The bearing part is connected to the active rod through the limiting post, and the active rod is slidably connected to the limiting post.

[0016] Preferably, the driving device further includes a motor, which is electrically connected to the active rod and is used to drive the active rod to slide along the limiting post in the first limiting groove;

[0017] A control switch is provided on the surface of the bearing part, and the control switch is electrically connected to the motor;

[0018] More preferably, the control switch is configured for both up control and down control:

[0019] When the descent switch is activated, the motor is controlled to start, driving the active rod to move from the edge of the first limiting groove towards the center. One end of the connecting rod moves towards the center of the first limiting groove along with the active rod, while the other end drives the driven rod to move downward along the second limiting groove, thus driving the cone head body to move downward.

[0020] When the lifting switch is activated, the motor is controlled to start, driving the active rod to move from the center of the first limiting groove to the edge. One end of the connecting rod moves along with the active rod towards the edge of the first limiting groove, while the other end drives the driven rod to move upward along the second limiting groove, thus driving the cone head body to move upward.

[0021] Preferably, the formula for calculating the downward movement length of the driven rod is:

[0022]

[0023] Where a is the distance from the first fixed rod to the center of the first limiting groove, b is the distance from the second fixed rod to the top of the second limiting groove, r is the length of the connecting rod, n is the moving distance of the active rod, and m is the moving distance of the cone head body driven by the driven rod.

[0024] Compared with existing technologies, the puncture awl for tire lining provided by this invention has the following advantages: The puncture awl includes a handle, a drive device, and a cone head. The drive device electrically controls the cone head to precisely change the length of the awl. Based on the thickness of the tire lining, the puncture depth is marked, and the awl is adjusted to the marked position. The puncture depth must not exceed the marked depth to avoid tire blowouts caused by air leaks. Using electronic control instead of manual adjustment of the awl length allows for more precise length changes. Furthermore, with a limiting structure at one end of the drive lever, the length of the cone head can be controlled manually by moving the drive lever, ensuring continued usability even in the event of a control system malfunction.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0036] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0037] like Figure 1 As shown, Figure 1 This is a schematic diagram of the overall structure of an awl for piercing lining provided by an embodiment of the present invention; it can be seen that the awl for piercing lining provided by the present invention includes: a handle and a head; wherein the handle includes a grip and a connecting part 103, and the handle is connected to the head through the connecting part 103; the head includes a head body 202 and a supporting part 201, one end of the supporting part 201 is fixedly connected to the connecting part 103, and the other end is connected to the head body 202 through a driving device 300.

[0038] Specifically, the connecting part 103 is a housing, one end of which is threaded to the gripping part and the other end of which is connected to the cone head; the gripping part includes a cover end 102 and a protective sleeve 101, one end of the protective sleeve 101 is threaded to the cone head and the other end is fixedly connected to the cover end 102.

[0039] Specifically, a drive device 300 is provided inside the connecting part 103, and the drive device is fixedly connected to the cone head.

[0040] Specifically, the drive device 300 includes a drive rod 303, a driven rod 305, and a connecting rod 306; the drive rod 303 is disposed inside the bearing part 201 and is connected to the driven rod 305 through the connecting rod 306, and the bearing part 201 is connected to the cone head body 202 through the driven rod 305.

[0041] For a clearer view of the drive unit 300 structure, please refer to [reference needed]. Figure 3 and Figure 4 , Figure 3 This is a schematic diagram of the driving device 300 for a lining piercing awl provided in an embodiment of the present invention; Figure 4 This is a side view of a driving device 300 for a lining eyelet awl provided in an embodiment of the present invention.

[0042] It can be seen that one end of the active rod 303 is provided with a through hole, and a first fixed rod 308a is fixedly connected inside the through hole. The length of the first fixed rod 308a is greater than the width of the active rod 303. One end of the connecting rod 306 is connected to the first fixed rod 308a. When the connecting rod 306 is only connected to the first fixed rod 308a, the connecting rod 306 can rotate around the first fixed rod 308a.

[0043] It can also be seen that one end of the driven rod 305 is also provided with a through hole, and a second fixed rod 308b is fixedly connected inside the through hole. The length of the second fixed rod 308b is greater than the width of the driven rod 305. The other end of the connecting rod 306 is connected to the second fixed rod 308b. When the connecting rod 306 is only connected to the second fixed rod 308b, the connecting rod 306 can rotate around the second fixed rod 308b.

[0044] In this situation, when the driving rod 303 moves from the edge of the first limiting groove 307a toward the center, one end of the connecting rod 306 moves toward the center of the first limiting groove 307a together with the driving rod 303, and the other end drives the driven rod 305 to move downward along the second limiting groove 307b, thereby driving the cone head body 202 to move downward; thus adjusting the length of the cone head body 202.

[0045] The bearing part 201 has a first limiting groove 307a and a second limiting groove 307b inside. The first limiting groove 307a is provided with a limiting post 304. The bearing part 201 is connected to the driving rod 303 through the limiting post 304, and the driving rod 303 is slidably connected to the limiting post 304. In this way, the driving rod 303 and the driven rod 305 can only move along the limiting grooves that match them, thereby changing the position of the driven rod 305 under the action of the connecting rod 306, and thus changing the length of the cone.

[0046] Specifically, the drive device 300 also includes a motor 302, which is electrically connected to the drive rod 303 and is used to drive the drive rod 303 to slide along the limit post 304 in the first limit groove 307a;

[0047] More specifically, a control switch 301 is provided on the surface of the bearing part 201, and the control switch 301 is electrically connected to the motor 302;

[0048] Control switch 301 is configured for both up control and down control:

[0049] When the descent control switch 301 is activated, the control motor 302 is activated to drive the active rod 303 to move from the edge of the first limiting groove 307a toward the center. One end of the connecting rod 306 moves toward the center of the first limiting groove 307a together with the active rod 303, and the other end drives the driven rod 305 to move downward along the second limiting groove 307b, thereby driving the cone head body 202 to move downward.

[0050] When the lifting control switch 301 is activated, the control motor 302 starts to drive the active rod 303 to move from the center of the first limiting groove 307a to the edge. One end of the connecting rod 306 moves along with the active rod 303 to the edge of the first limiting groove 307a, while the other end drives the driven rod 305 to move upward along the second limiting groove 307b, thereby driving the cone head body 202 to move upward.

[0051] In this way, the length of the cone can be precisely changed by the drive device 300 electronically controlled cone. According to the thickness of the tire inner liner, the depth of the puncture is marked with a paint pen or tape, and then the cone is adjusted to the marked position. The puncture depth must not exceed the marked depth to avoid tire blowout caused by tire leakage.

[0052] The formula for calculating the downward movement length of the driven rod 305 is:

[0053]

[0054] Where a is the center distance from the first fixed rod 308a to the first limiting groove 307a, b is the distance from the top of the second fixed rod 308b to the second limiting groove 307b, r is the length of the connecting rod 306, n is the moving distance of the driving rod 303, and m is the moving distance of the driven rod 305 driving the cone body 202.

[0055] As can be seen, the center distance 'a' from the first fixing rod 308a to the first limiting groove 307a, the distance 'b' from the top of the second fixing rod 308b to the second limiting groove 307b, and the length 'r' of the connecting rod 306 are all known. Therefore, changing the moving distance of the active rod 303 can change the moving distance of the cone body 202, thereby changing the overall length of the cone. Based on the thickness of the tire inner liner, after marking the puncture depth with a paint pen or tape, the cone is adjusted to the marked position. The puncture depth must not exceed the marked depth to avoid tire blowout caused by tire leakage.

[0056] The control center (not shown in the figure) at the control switch 301 is configured to precisely control the movement distance of the cone body 202 by inputting the required movement distance of the active lever 303, thereby precisely changing the overall length of the cone.

[0057] In summary, this invention provides an awl for puncturing tire liner, comprising a handle, a drive device 300, and a cone head. The drive device 300 electrically controls the cone head to precisely change the length of the awl. Based on the tire liner thickness, the puncture depth is marked using a paint pen or tape, and the awl is adjusted to the marked position. The puncture depth must not exceed the marked depth to avoid tire blowouts caused by air leaks. Using electronic control to replace manual adjustment of the awl length allows for more precise modification to the required length.

[0058] In addition, the drive unit 300 may also have another manual structure; please refer to [reference needed]. Figure 2 , Figure 2 This is a schematic diagram of the overall structure of an inner-lined eye-piercing awl using another driving device 300 provided in an embodiment of the present invention;

[0059] As can be seen, the first limiting groove 307a inside the bearing part 201 extends outward to the outside. In use, the motor 302 does not drive the active rod 303 to move the cone body 202. Instead, a mechanical structure is used for operation. This structure requires a limiting structure (not shown in the figure) at the end of the active rod 303 exposed outside the bearing part 201. The position of the active rod 303 can be fixed according to the actual needs of the operator. Based on the thickness of the tire inner liner, the depth of the puncture can be marked with a paint pen or tape, and the cone can be adjusted to the marked position. The puncture depth should not exceed the marked depth to avoid tire blowout caused by tire leakage.

[0060] Similarly, the formula for calculating the downward movement length of the driven rod 305 is:

[0061]

[0062] Where a is the center distance from the first fixed rod 308a to the first limiting groove 307a, b is the distance from the top of the second fixed rod 308b to the second limiting groove 307b, r is the length of the connecting rod 306, n is the moving distance of the driving rod 303, and m is the moving distance of the driven rod 305 driving the cone body 202.

[0063] As can be seen, the center distance 'a' from the first fixing rod 308a to the first limiting groove 307a, the distance 'b' from the top of the second fixing rod 308b to the second limiting groove 307b, and the length 'r' of the connecting rod 306 are all known. Therefore, changing the moving distance of the active rod 303 can change the moving distance of the cone body 202, thereby changing the overall length of the cone. Based on the thickness of the tire inner liner, after marking the puncture depth with a paint pen or tape, the cone is adjusted to the marked position. The puncture depth must not exceed the marked depth to avoid tire blowout caused by tire leakage.

[0064] To further improve this solution, a certain number of markings are set on the end of the active lever 303 exposed on the outside of the bearing part 201 according to the actual situation, so as to quickly switch to the required cone length, which is convenient for changing the specific tire liner thickness in actual use.

[0065] In summary, the awl for puncturing tire liner provided in the second embodiment of the present invention includes a shank, a drive device 300, and a cone head. The drive device 300 controls the cone head to change the length of the awl. Based on the tire liner thickness, the puncture depth is marked using a paint pen or tape, and the awl is adjusted to the marked position. The puncture depth must not exceed the marked depth to avoid tire blowouts caused by air leaks. The cooperation of the drive rod 303 and the driven rod 305 allows for more precise control of the awl length. Furthermore, when the drive rod 303 is marked with a commonly used tire liner thickness on the side exposed outside the support portion 201, the awl length can be changed more quickly and then fixed by a limiting structure, preventing instability in the awl length due to movement of the drive rod 303 during use.
