Description

Technical Field

[0001] This application relates to the field of embryo processing technology, and in particular to an apparatus for puncturing embryos. Background Technology

[0002] In the field of agricultural tire processing, with the continuous development of agricultural machinery, the requirements for the quality and production efficiency of agricultural tires are also increasing. The processing of agricultural tires, such as bias tires, involves multiple stages, among which the piercing process is crucial for the subsequent vulcanization process. Piercing allows for the release of gases during vulcanization, ensuring the quality of the finished tire.

[0003] Currently, in related technologies, large-size bias-ply tire blanks are usually transported by using bias-ply tire blank carriers to move the tire blanks to the vicinity of the puncturing machine equipment.

[0004] However, the underside of the bias-ply tire blank cart in the relevant technology is unsupported. If stored for a long time, the tire blank will deform into an elliptical shape due to gravity, which will seriously affect the quality of the finished product.

[0005] The aforementioned technologies have the drawback that embryos are prone to deformation when stored for extended periods. Utility Model Content

[0006] To address the issue of embryo deformation during prolonged storage, this application provides an embryo puncture processing device.

[0007] The tire blank piercing processing device provided in this application adopts the following technical solution: A tire blank piercing processing device for processing tire blanks includes: a piercing mechanism for piercing the tire blank; and a conveying mechanism that cooperates with the piercing mechanism to move the tire blank into or out of the piercing station of the piercing mechanism. The conveying mechanism includes a bearing component, a support component, and an adjusting component. The bearing component is used to support the tire blank. The support component and the adjusting component are both disposed on the bearing component. The support component includes a support member and two connecting members. The connecting members are respectively disposed on opposite sides of the bearing component. The two ends of the support member are respectively connected to the two connecting members. The support member is used to support the bottom of the tire blank. The adjusting component is connected to the connecting members and is used to adjust the length of the support member between the two connecting members.

[0008] By adopting the above technical solution, the conveying mechanism can cooperate with the piercing mechanism to move the tire blank into or out of the piercing station of the piercing mechanism; the piercing mechanism can perform piercing operations on the tire blank to prepare for the emission of gases in the subsequent vulcanization process. The load-bearing component can support the support component and the adjusting component, providing them with an installation foundation; the load-bearing component is used to support the tire blank, and the support component's support member can support the bottom of the tire blank, preventing deformation of the tire blank due to prolonged placement on the load-bearing component without lower support, thus affecting the quality of the final product; two connecting members are respectively located on opposite sides of the load-bearing component, connecting the two ends of the support member; the adjusting component connects to the connecting members, allowing the length of the support member between the two connecting members to be adjustable, thus adapting to tires of different specifications and providing better lower tire support.

[0009] Optionally, the support member is flexible.

[0010] By adopting the above technical solution, the support component is used to support the bottom of the tire blank. The support component is flexible, which allows it to better fit tire blanks of different specifications. When supporting the tire blank, it can adaptively deform according to the shape of the tire blank, avoiding damage to the tire blank caused by rigid support. At the same time, it can also provide more stable support, preventing the tire blank from deforming due to shaking or uneven support during transportation. This improves the stability and safety of the tire blank during transportation and processing, thereby ensuring the quality of the tire blank.

[0011] Optionally, the connector is rotatably connected to the support assembly, and the adjustment assembly is used to drive the connector to rotate. The rotation of the connector can cause the support to be wound or released, so as to adjust the length of the support between the two connectors.

[0012] By adopting the above technical solution, the adjusting component drives the connecting part to rotate. Since the connecting part rotates and connects to the supporting component, the rotating part can drive the flexible supporting part to wind or release, thereby adjusting the length of the supporting part between the two connecting parts. This allows the supporting part to adjust its length according to the needs of different specifications of the tire blank, thus better supporting the tire blank and avoiding tire blank deformation due to lack of support at the bottom, ensuring the quality of the finished product.

[0013] Optionally, the adjustment component includes a handwheel connected to the end of the connector, the handwheel being used to drive the connector to rotate.

[0014] By adopting the above technical solution, the handwheel is connected to the end of the connector. The operator can turn the handwheel to drive the connector to rotate. Since the two ends of the support are connected to two connectors respectively, the rotation of the connector can drive the support to wind or release, thereby adjusting the length of the support between the two connectors. This allows the support to adjust the support length according to different specifications of the tire blank, so as to better support the tire blank.

[0015] Optionally, the adjustment assembly includes a ratchet and a pawl, the ratchet being connected to the connector, the pawl being rotatably connected to the bearing assembly, and the pawl cooperating with the ratchet to limit the reverse rotation of the ratchet.

[0016] By adopting the above technical solution, the ratchet in the adjustment component is connected to the connector and can rotate with the rotation of the connector, thereby driving the support component to wind or release, so as to adjust the length of the support component between the two connectors; the pawl is rotatably connected to the bearing component and cooperates with the ratchet, which can limit the ratchet to rotate in the opposite direction, thereby fixing the adjusted length of the support component, ensuring stable support for the tire blank, and enabling the conveying mechanism to adapt to the bearing requirements of tire blanks of different specifications.

[0017] Optionally, the first end of the pawl is rotatably connected to the bearing assembly, and the second end of the pawl is engaged with the ratchet.

[0018] By adopting the above technical solution, the first end of the pawl is rotatably connected to the bearing component, allowing the pawl to rotate around the connection point as an axis, providing a basis for the pawl's movement; the second end of the pawl is attached to the ratchet, and when the ratchet rotates in the forward direction, the pawl can slide on the back of the ratchet teeth without affecting the forward rotation of the ratchet; while when the ratchet rotates in the reverse direction, the pawl can engage with the ratchet teeth, restricting the reverse rotation of the ratchet, ensuring the stability and reliability of the support component after the adjustment component adjusts the length of the support component, thereby ensuring the stability of the support component in supporting the tire blank.

[0019] Optionally, the adjustment components are provided in two sets, and the adjustment components are correspondingly arranged with the connectors.

[0020] By adopting the above technical solution, two sets of adjustment components are set up and correspond to the connecting parts, so that each connecting part can be adjusted individually by the corresponding adjustment component. In this way, the two connecting parts can be precisely adjusted according to the different specifications of the tire blank and the actual support requirements, thereby flexibly adjusting the length of the support part between the two connecting parts, so that the support part can better adapt to the size of different tire blanks, and enhance the adaptability and stability of tire blank support.

[0021] Optionally, the support assembly includes a support frame and a plurality of casters, the support assembly and the adjustment assembly are both disposed on the support frame, and the plurality of casters are distributed below the support frame.

[0022] By adopting the above technical solution, the support frame is used to install the support component and the adjustment component, providing support and installation foundation for the entire conveying mechanism; the casters are distributed under the support frame, which allows the support component to move flexibly, making it easy to move the tire blank into or out of the piercing station of the piercing mechanism, thus improving the mobility and ease of operation of the conveying mechanism.

[0023] Optionally, the piercing mechanism includes a support frame, a piercing component, a support shaft, and a moving assembly. The moving assembly and the piercing component are both mounted on the support frame. The moving assembly is throttle-connected to the support shaft. The support shaft supports the tire blank, allowing the tire blank to be mounted at the piercing station. The piercing component is located above the piercing station. The moving assembly is used to adjust the height of the support shaft.

[0024] By adopting the above technical solution, the support frame serves to support the entire piercing mechanism, providing an installation base for the piercing component, support shaft, and moving assembly; the piercing component is located above the piercing station and can perform piercing operations on the tire blank at the piercing station; the support shaft is used to support the tire blank, allowing it to be placed at the piercing station and ensuring the smooth progress of the piercing operation; the moving assembly is connected to the support shaft via a transmission, and can adjust the height of the support shaft to accommodate tire blanks of different specifications, facilitating the accurate placement of the tire blank at the piercing station and enabling the piercing component to pierce the tire blank, thereby improving the flexibility and applicability of the piercing process.

[0025] Optionally, the moving component includes a drive unit, a guide rail, a valve body, and a sensor. The sensor, the drive unit, and the guide rail are all mounted on the support frame. The sensor is used to detect the height of the tire blank on the support shaft. The support shaft is slidably connected to the guide rail, which extends vertically. The output end of the drive unit is driven to the support shaft to drive the support shaft to move vertically. The sensor is electrically connected to the valve body, and the valve body is connected to the drive unit, so that the support shaft can stop at any height, allowing the piercing device to pierce the tire blank on the support shaft.

[0026] By adopting the above technical solution, the sensor can detect the height of the tire blank on the support shaft, providing data for the drive component to move the support shaft vertically; the output end of the drive component is connected to the support shaft, enabling the support shaft to move vertically along the vertically extending guide rail to adjust the height of the support shaft and the tire blank; the guide rail provides guidance for the movement of the support shaft, ensuring its stability and accuracy; the valve body is connected to the drive component, allowing the support shaft to stop at a suitable height based on the tire blank height detected by the sensor, thus facilitating the piercing component to pierce the tire blank on the support shaft, and adapting to the piercing requirements of tire blanks of different heights.

[0027] In summary, this application includes at least one of the following beneficial technical effects: 1. The support component supports the tire blank, solving the problem of the original bias tire blank having no support at the bottom, preventing the tire blank from deforming due to gravity, and ensuring the quality of the finished product in the later stage; 2. The adjustable component allows for adjustment of the support length, accommodating different sizes of tire blanks and improving applicability; 3. The moving component of the piercing mechanism allows the pierced part to stop at any height, solving the problem of fixed position of the cylinder lifting position of the piercing machine, and facilitating the processing of blanks of different specifications.

[0034] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be further described in detail below. In this embodiment, unless otherwise specified, "connection", "linking", and "fixing" are interpreted broadly, including fixed connection, detachable connection, connection to form an integral structure, mechanical connection, electrical connection, direct connection, indirect connection through an intermediary, internal connection, and interaction between two components, etc., and can be understood according to the specific circumstances.

[0035] In this application, unless otherwise expressly specified and limited, "above" or "below" a second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, in the description of this embodiment, terms such as "above," "below," "left," and "right," etc., are based on the orientation or positional relationships shown in the accompanying drawings and are used only for ease of description and simplification of operation. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Unless otherwise stated, directional terms such as "inner" and "outer" used in this application refer to the outline of the corresponding component itself.

[0036] like Figure 1 and Figure 2 As shown in the figure, this application discloses a tire blank piercing processing apparatus (hereinafter referred to as the "apparatus"). The apparatus includes a piercing mechanism 1 and a conveying mechanism 2, and is used to process tire blanks 100.

[0037] The conveying mechanism 2 works in conjunction with the piercing mechanism 1 to move the tire blank 100 into or out of the piercing station of the piercing mechanism 1. The piercing mechanism 1 is used to pierce the tire blank 100 to prepare for the emission of gas in the subsequent vulcanization process.

[0038] like Figure 1 , Figure 2 and Figure 3 As shown, the conveying mechanism 2 includes a load-bearing component 21, a support component 22, and an adjusting component 23. The load-bearing component 21 is used to support the tire blank 100, so that the tire blank 100 is suspended on the load-bearing component 21. The load-bearing component 21 provides the mounting base, and the support component 22 and the adjusting component 23 are both disposed on the load-bearing component 21.

[0039] The support assembly 22 includes a support member 221 and two connecting members 222. The connecting members 222 are respectively located on opposite sides of the support assembly 21, allowing the tire blank 100 to be positioned between the two connecting members 222. The two ends of the support member 221 are connected to the two connecting members 222 respectively. The support member 221 supports the bottom of the tire blank 100, preventing deformation of the tire blank 100 due to prolonged placement on the support assembly 21 without lower support, thus affecting the quality of the final product. The adjustment assembly 23 connects to the connecting members 222 and is used to adjust the length of the support member 221 between the two connecting members 222, making it adaptable to tires of different specifications and providing better lower tire support.

[0040] like Figure 1 , Figure 2 and Figure 3As shown, the supporting component 21 includes a supporting frame 211 and several casters 212. The supporting component 22 and the adjusting component 23 are both mounted on the supporting frame 211, which provides support and a mounting base for the entire conveying mechanism 2. The casters 212 are distributed below the supporting frame 211, allowing the supporting component 21 to move flexibly, facilitating the movement of the tire blank 100 into or out of the piercing position of the piercing mechanism 1, thus improving the mobility and ease of operation of the conveying mechanism 2.

[0041] like Figure 2 and Figure 3 As shown, the support frame 211 includes a support frame 2111 and a support body 2112. The support frame 2111 supports other structures, and the support body 2112 is mounted on the support frame 2111 to support the tire blank 100, allowing the tire blank 100 to be hung on the support body 2112 for transport. A slide rail can be provided on the support frame 2111, allowing the support body 2112 to slide and adjust its height. Correspondingly, the support frame 2111 has a limiting structure, such as a fastening hole and bolt engagement structure, to ensure that the support body 2112 can be fixed at a certain height after vertical sliding, improving reliability. The specific structure of the support frame 2111 and the support body 2112 is not limited and can be configured as needed.

[0042] The support frame 211 is also equipped with a handle 213 to facilitate manual movement of the conveying mechanism 2 by the operator. The support frame 211 can also be equipped with a pulling member 214, which facilitates mechanical pulling of the conveying mechanism 2, improves conveying efficiency, and reduces labor intensity.

[0043] like Figure 2 and Figure 3 As shown, the support member 221 is flexible, which allows it to better conform to different specifications of the tire blank 100. When supporting the tire blank 100, it can adaptively deform according to the shape of the tire blank 100, avoiding damage to the tire blank 100 caused by rigid support. At the same time, the flexible support member 221 also provides more stable support, preventing the tire blank 100 from deforming due to shaking or uneven support during transportation, improving the stability and safety of the tire blank 100 during transportation and processing, thereby ensuring the quality of the tire blank 100. In this embodiment, the support member 221 can be a fabric curtain.

[0044] Optionally, the connector 222 can be a rotating shaft structure, with the end of the fabric fixed to the rotating shaft structure by rivets. The connector 222 rotatably connects to the support assembly 22, and the adjusting assembly 23 drives the connector 222 to rotate. The rotation of the connector 222 can cause the flexible support 221 to be wound around the connector 222 or released from the connector 222, thereby adjusting the length of the support 221 between the two connectors 222. This allows the support 221 to be adjusted in length according to the needs of different specifications of the tire blank 100, thereby better supporting the tire blank 100, avoiding deformation of the tire blank 100 due to lack of support at the bottom, and ensuring the quality of the finished product.

[0045] like Figure 2 , Figure 3 and Figure 4 As shown, the adjustment assembly 23 includes a handwheel 231. The handwheel 231 is connected to the end of the connector 222 and is used to drive the connector 222 to rotate. The operator can manually turn the handwheel 231 to drive the connector 222 to rotate. Since the two ends of the support member 221 are respectively connected to two connectors 222, the rotation of the connector 222 can drive the support member 221 to wind or unwind, thereby adjusting the length of the support member 221 between the two connectors 222. This allows the support member 221 to adjust its support length according to different specifications of the tire blank 100, thus better supporting the tire blank 100.

[0046] Optionally, the adjusting assembly 23 includes a ratchet 232 and a pawl 233. The ratchet 232 is connected to the connecting member 222 and can rotate with the rotation of the connecting member 222. By turning the handwheel 231, the connecting member 222 and the ratchet 232 can be rotated, thereby causing the support member 221 to be wound or released, so as to adjust the length of the support member 221 between the two connecting members 222. The pawl 233 is rotatably connected to the bearing assembly 21. The pawl 233 cooperates with the ratchet 232 to limit the reverse rotation of the ratchet 232, thereby fixing the adjusted length of the support member 221, ensuring stable support for the tire blank 100, and enabling the conveying mechanism 2 to adapt to the bearing requirements of tire blanks 100 of different specifications.

[0047] like Figure 2 , Figure 3 and Figure 4As shown, the first end of the pawl 233 is rotatably connected to the bearing assembly 21, allowing the pawl 233 to rotate around this connection point, providing a basis for its movement. The second end of the pawl 233 is attached to the ratchet 232; specifically, the pawl 233 can use its own weight to attach to the ratchet 232, thus limiting the reverse rotation of the ratchet 232. When the ratchet 232 rotates forward, the pawl 233 can slide on the back of the teeth of the ratchet 232 without affecting its forward rotation; while when the ratchet 232 rotates in the reverse direction, the pawl 233 can engage with the tooth groove of the ratchet 232, limiting its reverse rotation and achieving self-locking. This ensures the stability and reliability of the support member 221 after the adjusting assembly 23 adjusts its length, thereby ensuring the stability of the support member 221 in supporting the tire blank 100. Furthermore, the specific structure of the pawl 233 is not limited. When the ratchet 232 is rotated in the forward direction, the second end of the pawl 233 can also be manually lifted to achieve smoother rotation and reduce rotational resistance.

[0048] like Figure 2 , Figure 3 and Figure 5 As shown, there are two sets of adjustment components 23, each corresponding to a connector 222, allowing each connector 222 to be adjusted individually by its corresponding adjustment component 23. This allows for precise adjustment of the two connectors 222 according to different specifications of the tire blank 100 and actual support requirements, thereby flexibly adjusting the length of the support member 221 between the two connectors 222. This makes the support member 221 better adaptable to different tire blank 100 sizes, enhancing the adaptability and stability of the support for the tire blank 100. Furthermore, the slide rail on the support frame 211 can be positioned on the side facing the tire blank 100 to reduce the risk of interference with the support body 2112.

[0049] like Figure 1 , Figure 2 and Figure 3 As shown, the piercing mechanism 1 includes a support frame 11, a piercing element 12, a support shaft 14, and a moving assembly 13. The support frame 11 supports the entire piercing mechanism 1 and provides a mounting base for the piercing element 12, the support shaft 14, and the moving assembly 13. The piercing element 12 is located above the piercing station and can pierce the tire blank 100 at the piercing station. Both the moving assembly 13 and the piercing element 12 are mounted on the support frame 11. The support shaft 14 supports the tire blank 100, and the moving assembly 13 is connected to the support shaft 14 for transmission. The moving assembly 13 is used to adjust the height of the support shaft 14 to accommodate tire blanks of different specifications, facilitating accurate placement of the tire blank 100 at the piercing station and enabling the piercing element 12 to pierce the tire blank 100, thus improving the flexibility and applicability of the piercing process. Specifically, the specific structures of the support frame 11, the piercing element 12, and the support shaft 14 can be selected from existing structures as needed and are not limited here.

[0050] Optionally, the moving component 13 includes a drive element 131, a guide rail 132, a valve body, and a sensor (not shown in the figure). The sensor, drive element 131, and guide rail 132 are all mounted on the support frame 11. The sensor is used to detect the height of the tire blank 100 on the support shaft 14, providing data for the drive element 131 to drive the support shaft 14 to move vertically. The guide rail 132 extends vertically, and the support shaft 14 is slidably connected to the guide rail 132. The guide rail 132 provides guidance for the movement of the support shaft 14, ensuring its stability and accuracy.

[0051] like Figure 1 , Figure 2 and Figure 3 As shown, the output end of the drive unit 131 is connected to the support shaft 14, which drives the support shaft 14 to move vertically along the guide rail 132 to adjust the height of the support shaft 14 and the tire blank 100 on it. The valve body is connected to the drive unit 131, allowing the support shaft 14 to stop at any height. The sensor is electrically connected to the valve body, and can stop the support shaft 14 at a suitable height based on the height of the tire blank 100 detected by the sensor. This facilitates the piercing unit 12 to pierce the tire blank 100 on the support shaft 14, adapting to the piercing requirements of tire blanks 100 at different heights. The device may also include a control mechanism, which is electrically connected to the necessary structures of the piercing mechanism 1, so as to adjust the valve body and the drive unit 131 according to the detection results of the sensor, raising tire blanks 100 of different specifications to a suitable height, enabling the piercing unit 12 to reliably pierce tire blanks 100 of different specifications, improving reliability and applicability. The valve body design makes it easy to adjust the lifting and stopping position of the drive component 131. Compared with the original piercing machine where the support shaft can only stop at the lowest and highest points, this device can easily cooperate with the conveying mechanism 2 and is suitable for piercing operations of different specifications of tire blanks 100, thus improving applicability.

[0052] The specific types of the drive component 131, valve body, and sensor are not limited. For example, the drive component 131 can be a cylinder, hydraulic cylinder, or other structure capable of extension and retraction; the valve body can be a center-sealed valve, a three-position five-way solenoid valve, or other valve body that allows the drive component 131 to stop at any position. Given existing related technologies, their connection and implementation principles will not be detailed here; the sensor can be a distance sensor; and the control mechanism can be a PLC. The stroke of the drive component 131 and the length of the guide rail 132, among other parameters, can be set as needed. The connection and operating principles of the support frame 11, the piercing component 12, the drive component 131, and the support shaft 14 of the piercing mechanism 1 can refer to existing piercing machines and will not be detailed here. For example, the piercing component 12 can be lifting and lowering, and the piercing needle of the piercing component 12 can rotate, as can the support shaft 14, and other related parameters such as rotation angles. Existing data can be used, or settings can be made as needed to meet the usage requirements; no specific restrictions are imposed here.

[0053] like Figure 1 , Figure 2 and Figure 3 As shown, this device further reduces the difficulty of transporting large-sized tire blanks, such as 30-38 inch tire blanks. Since the support shaft 14 of this device can stop at any height, after the tire blank 100 is transported to the piercing station via the conveying mechanism 2, the support shaft 14 can reliably support and drive the tire blank 100, reducing the need for manual transfer of the tire blank 100 from the conveying mechanism 2 to the support shaft 14, and improving the ease of cooperation between the support shaft 14 and the conveying mechanism 2. After the support shaft 14 supports the tire blank 100, the conveying mechanism 2 can be moved out of the piercing station, reducing the risk of interference, allowing the support shaft 14 to adjust the height of the tire blank 100 for piercing operations. When the conveying mechanism 2 cooperates with the piercing mechanism 1, the height of the support shaft 14 can be lowered first by the moving component 13, allowing the conveying mechanism 2 to move into the piercing position. At this time, the support shaft 14 passes through the inner hole in the middle of the tire blank 100, and the tire blank 100 is lifted by the support shaft 14, while the conveying mechanism 2 is moved out of the piercing position. After the sensor detection results show that the upper end of the tire blank 100 has been raised to a suitable height, the support shaft 14 stops moving. At this time, the piercing component 12 rotates to start piercing the tire blank 100. The support shaft 14 can rotate, and the piercing operation can be repeated a set number of times to facilitate the discharge of gas through the piercing during the vulcanization process. After the piercing is completed, the support shaft 14 descends, the conveying mechanism 2 moves back into the piercing position, and supports the tire blank 100, and then moves the tire blank 100 out of the piercing position.

[0054] It is understandable that the device also includes necessary structures for connection, support, drive, positioning, limiting and control functions, so that the device can operate normally; the shape, size, material and number of each part of the device can be determined as needed, as long as the corresponding functions can be achieved.

[0055] The implementation principle of the tire blank piercing processing device in this application embodiment is as follows: The supporting component 22 and the adjusting component 23 of the conveying mechanism 2 are both set on the bearing component 21. The two ends of the supporting member 221 of the supporting component 22 are respectively connected to the connecting members 222 on opposite sides of the bearing component 21. The adjusting component 23 is connected to the connecting members 222, and can adjust the connecting members 222, thereby adjusting the length of the supporting member 221 between the two connecting members 222. In this way, when processing tire blanks 100 of different specifications, the length of the supporting member 221 can be changed by adjusting the connecting members 222 through the adjusting component 23, so that the supporting member 221 can better adapt to the diameter of tire blanks 100 of different specifications, achieve effective support for the lower part of the tire blank 100, avoid deformation of the tire blank 100 due to lack of support at the bottom during long-term storage, and improve the quality of the finished product. At the same time, the conveying mechanism 2 works in conjunction with the piercing mechanism 1 to smoothly move the tire blank 100 into or out of the piercing station of the piercing mechanism 1. The piercing mechanism 1 performs piercing processing on the tire blank 100 to complete the piercing operation on the tire blank 100.

[0056] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
