[0022] To address the problem of low efficiency in the weighing process of the embryo in existing technologies, this utility model provides a embryo support device and a molding machine.

[0023] like Figure 1 The device shown includes a base 10, a weighing component 20, and a support component 30. The weighing component 20 and the support component 30 are both connected to the base 10 and are disposed on the same side of the base 10. The weighing component 20 and the support component 30 can both be located on the inner periphery of the fetal embryo 50. The support component 30 is expandable and contractable. The support component 30 has a supporting position for expanding and supporting the fetal embryo 50 and a weighing position for contracting and releasing the fetal embryo 50. When the support component 30 is in the weighing position, the weighing component 20 supports the fetal embryo 50 and weighs it.

[0024] The embodiment integrates the weighing assembly 20 and the collapsible supporting assembly 30 on the tire supporting device, so that the tire blank 50 can be supported and weighed on the tire supporting device, thereby improving the work efficiency and reducing the occupied space of the tire supporting device. Specifically, on the one hand, the supporting assembly 30 can release the tire blank 50 when it is collapsed, so that the tire blank 50 can be weighed at any time when it is located on the tire supporting device, and after the weighing is completed, the supporting assembly 30 can be inflated to quickly switch to the tire supporting position, without the need to transport the tire blank 50 to the weighing position, so that the weighing process does not occupy the time sequence alone, thereby improving the work efficiency of the weighing process and the flexibility of the weighing. On the other hand, the tire supporting device can support the tire blank 50 when the supporting assembly 30 is inflated, so that the tire supporting and tire unloading can be realized by the inflation and collapse of the supporting assembly 30, thereby facilitating the operations such as taking the tire blank 50, moving the tire blank 50 and unloading the tire blank 50, thereby improving the flexibility of the tire supporting device. In this way, the tire supporting device integrates the functions of taking the tire blank 50, supporting the tire blank 50, unloading the tire blank 50 and weighing the tire blank 50, and the operation is simple and convenient, thereby improving the work efficiency and saving the occupied space of the tire supporting device.

[0025] In the embodiment, the supporting assembly 30 comprises a plurality of tire supporting rollers 31, each of which is arranged along the circumferential side of the tire blank 50 and is movably arranged relative to the base 10 along the radial direction of the tire blank 50 to enable the supporting assembly 30 to switch between the weighing position and the tire supporting position. Specifically, each of the tire supporting rollers 31 is arranged in a columnar structure, and the axis of each of the tire supporting rollers 31 is consistent with the axis of the tire blank 50. Each of the tire supporting rollers 31 is uniformly distributed along the inner circumferential side of the tire blank 50 to form a ring-shaped supporting structure, thereby enabling comprehensive and stable contact with the surface of the tire blank 50 and ensuring the firmness and safety of the tire blank 50 during movement and turning. All of the tire supporting rollers 31 are movably arranged relative to the base 10 along the radial direction of the tire blank 50, thereby enabling the tire supporting rollers 31 to move in position along the radial direction of the tire blank 50 and enabling the supporting assembly 30 to flexibly switch between the tire supporting position and the weighing position, thereby achieving dynamic supporting and releasing of the tire blank 50. In the tire supporting position, the plurality of tire supporting rollers 31 are uniformly attached to the inner circumferential side of the tire blank 50 by radial expansion to form a stable ring-shaped supporting structure, thereby ensuring the stability and safety of the tire blank 50 during movement, turning, and label application. When weighing is required, the tire supporting rollers 31 are moved to a position close to the center of the tire blank 50 by radial contraction, thereby completely transferring the weight of the tire blank 50 to the weighing assembly 20. At this time, the tire blank 50 is only in contact with the weighing assembly 20, thereby achieving high-precision weighing without interference. Meanwhile, the tire supporting rollers 31 during the contraction process can completely avoid the weighing assembly 20, ensuring that the weighing precision is not affected by any external factors. In this way, the tire supporting device can not only ensure the stable transmission of the tire blank 50 but also achieve rapid online weighing, thereby greatly improving the production efficiency and automation level and ensuring the safety of the production process and the quality of the products.

[0026] In the embodiment, the weighing assembly 20 is located above the central axis of the supporting assembly 30. When the supporting assembly 30 is in the weighing position, the weighing assembly 20 is located on the outer circumferential side of the supporting assembly 30 and is hung with the tire blank 50, thereby ensuring the accuracy of the weighing result. Specifically, the tire supporting rollers 31 of the embodiment are arranged in four and are uniformly distributed along the circumferential side of the tire blank 50, and the weighing assembly 20 is arranged between the two upper tire supporting rollers 31. As shown in FIG. 2, when the tire supporting rollers 31 are in the tire supporting position, the tire supporting rollers 31 are uniformly attached to the inner circumferential side of the tire blank 50 by radial expansion to form a ring-shaped supporting structure, thereby ensuring the stability and safety of the tire blank 50 during movement, turning, and label application. Figure 1As shown, the weighing assembly 20 of the present embodiment is located directly above the central axis of the supporting assembly 30, so as to ensure the center stability of the tire blank 50 during weighing and the accuracy of the weighing result. When the supporting assembly 30 is in the weighing position, i.e. the tire supporting roller 31 is contracted in the radial direction, the outer circumferential side of the tire supporting roller 31 is no longer in contact with the tire blank 50, at which time the weighing assembly 20 can quickly and accurately realize seamless hanging with the outer circumferential side of the tire blank 50, so that the weighing assembly 20 and the tire blank 50 form a direct supporting and weighing hanging. In this way, on the one hand, the contraction of the tire supporting roller 31 can provide sufficient operating space for the weighing assembly 20, and can avoid the weighing error that may be caused by the contact between the tire blank 50 and the tire supporting device during the conventional weighing process, so as to ensure the accuracy and consistency of the weighing data, on the other hand, the tire supporting device realizes seamless integration of the weighing and tire supporting functions, and the entire weighing process is accurate and rapid, which can reduce manual operation, thereby improving the weighing efficiency, and at the same time, avoiding the safety risk that may be caused by the direct contact of the operator with the tire blank 50. At the same time, when the supporting assembly 30 is in the tire supporting position, the supporting assembly 30 supports the tire blank 50, so as to avoid the long-term stress of the weighing assembly 20, thereby being conducive to improving the service life of the weighing assembly 20, thereby reducing the failure rate of the weighing assembly 20, and further improving the overall working efficiency of the tire supporting device. Of course, according to the actual situation, the weighing assembly 20 can also be slightly inclined to the vertical direction, not necessarily arranged directly above the central axis of the supporting assembly 30, as long as the tire blank 50 can be hung on the weighing assembly 20 when the supporting assembly 30 is contracted, and the weighing can be smoothly completed. It should be noted that the upward and downward directions of the present embodiment refer to the upward and downward directions of the tire supporting device 1. Figure 1

[0027] ​In the embodiment, the supporting assembly 30 further comprises a mounting plate 32, the mounting plate 32 is vertically arranged, the surface of the mounting plate 32 is provided with a plurality of sliding tracks 321, the sliding tracks 321 converge at a point, and the tire supporting rollers 31 are movably arranged on the sliding tracks 321, so as to realize the expansion and contraction of the supporting assembly 30. Specifically, the mounting plate 32 of the embodiment is arranged as a square plate, a plurality of sliding tracks 321 are arranged on the side of the mounting plate 32 close to the tire supporting rollers 31, each sliding track 321 converges to a point on the central axis of the tire blank 50 from different directions, so as to form a radial guide rail system. The end of the tire supporting roller 31 close to the mounting plate 32 is provided with a sliding block structure, the sliding block structure is movably arranged on the sliding track 321, so as to realize the accurate movement of the tire supporting roller 31 along the sliding track 321, so that the supporting assembly 30 can run according to the predetermined track when expanding to the tire supporting position and contracting to the weighing position, so as to form a stable annular supporting structure, and ensure the operation accuracy and efficiency in the processes of taking and placing the tire blank 50, weighing and labeling. Optionally, a limiting structure can be arranged on the sliding track 321, the limiting structure comprises a first limiting block and a second limiting block, when the supporting assembly 30 expands to the tire supporting position, the first limiting block prevents the tire supporting roller 31 from continuing to move away from the axis of the tire blank 50, so as to limit the supporting assembly 30 at the tire supporting position, when the supporting assembly 30 contracts to the weighing position, the second limiting block prevents the tire supporting roller 31 from continuing to move close to the axis of the tire blank 50, so as to limit the supporting assembly 30 at the weighing position. Fine adjustment structures can be arranged at the positions of the first limiting block and the second limiting block, so that the expansion and contraction ranges of the tire supporting roller 31 can be fine adjusted according to the specific size and weight of the tire blank 50, so as to realize personalized supporting and releasing operations, so as to ensure that each tire blank 50 can obtain the best supporting effect, and meanwhile, potential damage to the tire blank 50 caused by excessive expansion or contraction is avoided. The embodiment is provided with four sliding tracks 321 and is arranged in a cross shape, so as to match the arrangement of the four tire supporting rollers 31, when the tire supporting rollers 31 are arranged in other numbers, the number of the sliding tracks 321 is correspondingly changed to match the number of the tire supporting rollers 31. The mounting plate 32 is provided with a through hole close to the weighing assembly 20, so as to facilitate the connection of the weighing assembly 20 and the base 10 through the through hole. Considering the saving of the occupied space of the tire supporting device, the mounting plate 32 of the embodiment is arranged vertically, so as to facilitate the compact layout of the forming machine. Of course, the shape of the mounting plate 32 is not limited thereto, and according to the actual situation, the mounting plate 32 can also be arranged as a circular plate or other shapes.

[0028] In the embodiment, the supporting assembly 30 further comprises a driving member which is drivingly connected with each of the tire supporting rollers 31 and drives all the tire supporting rollers 31 to move synchronously, so that the tire supporting rollers 31 can still form a ring-shaped supporting structure during movement, and the supporting assembly 30 can always provide consistent and stable supporting effect, thereby avoiding the problems of damage to the tire blank 50 or excessive shaking of the tire blank 50 during expansion and contraction. The driving member in the embodiment is provided as one, which drives four tire supporting rollers 31 to move synchronously. The driving member can directly drive one tire supporting roller 31 and drive the other three tire supporting rollers 31 to move synchronously through a transmission belt, or the driving member can drive four tire supporting rollers 31 simultaneously through a transmission member, as long as the four tire supporting rollers 31 can move synchronously. Of course, a plurality of driving members can be provided, each of which drives one tire supporting roller 31, and the plurality of driving members move synchronously and drive the plurality of tire supporting rollers 31 to move synchronously. Optionally, the driving member can be a servo motor, a pneumatic cylinder, etc. Considering that the weighing assembly 20 in the embodiment is arranged between the two tire supporting rollers 31 above the mounting plate 32, the driving member can be arranged to drive only the two tire supporting rollers 31 above to move synchronously. When the two tire supporting rollers 31 contract along the radial direction, the tire blank 50 can also fall to be hung with the weighing assembly 20, thereby realizing the weighing of the tire blank 50.

[0029] In the embodiment, the weighing assembly 20 comprises a weighing plate and a weighing sensor. The weighing plate is connected with the base 10 and extends along the axial direction of the tire blank 50. The weighing sensor is located at the upper surface of the weighing plate, so that when the supporting assembly 30 is located at the weighing position, the tire blank 50 can contact the weighing sensor, thereby ensuring the accuracy of the weighing structure. The weighing plate in the embodiment is provided as a long strip-shaped platform, the length direction of which extends along the axial direction of the tire blank 50, forming a stable and suitable supporting surface for the suspension of the tire blank 50. The weighing sensor is located at the upper surface of the weighing plate, directly below the suspension position of the tire blank 50, so as to directly contact the tire blank 50 and collect the weight information thereof. The weighing sensor is designed in an array arrangement, so as to comprehensively capture the weight distribution of different parts of the tire blank 50 and provide comprehensive data support for quality control in the tire production process. When the supporting assembly 30 is located at the weighing position, i.e., the tire supporting rollers 31 are contracted to be close to the axial line of the tire blank 50, and the tire blank 50 is completely supported by the weighing assembly 20, the weighing sensor can accurately weigh, thereby ensuring the accuracy and reliability of the data. Optionally, the upper surface of the weighing plate is provided with an anti-slip and protective coating, so as to avoid the sliding or abrasion of the tire blank 50 during the weighing process, and also protect the sensor from damage, which is conducive to prolonging the service life of the equipment.

[0030] In the present embodiment, the tire supporting device further comprises a labeling assembly 40, which is movably connected with the base 10, and is arranged at the outer circumferential side of the supporting assembly 30, so as to realize the fixed-point labeling of the tire blank 50. The labeling assembly 40 is movably integrated with the base 10, so as to allow the labeling assembly 40 to flexibly approach or move away from the tire blank 50, so as to on the one hand ensure the accuracy during the labeling operation, and on the other hand avoid other components when not performing the labeling operation. When the tire supporting roller 31 is expanded to the tire supporting position, the labeling assembly 40 is located at the side of the tire blank 50, so as to ensure the unobstructed and operation space during the labeling, and meanwhile, the expanded state of the tire supporting roller 31 provides an accurate positioning reference for the labeling device, so as to ensure the accuracy of the labeling position. When the supporting assembly 30 is in the weighing position, i.e. the tire supporting roller 31 is contracted to be close to the axis of the tire blank 50, the labeling assembly 40 can automatically move away from the tire blank 50, so as to avoid the collision with the weighing assembly 20 or other mechanisms, and meanwhile, can provide sufficient operation space for the weighing assembly 20.

[0031] In the embodiment, the labeling assembly 40 comprises a swing frame, a barcode stripping module for stripping the labels, a labeling module for pasting the labels, and a code reading module for reading the label information. The swing frame is rotatably connected with the base 10 to approach or move away from the tire blank 50. The barcode stripping module, the labeling module, and the code reading module are connected with the swing frame, and the barcode stripping module, the labeling module, and the code reading module rotate synchronously with the swing frame. In this way, the labeling assembly 40 can not only ensure the accuracy of the labeling process, but also optimize the tire blank 50 processing flow, thereby improving the automation level and work efficiency of the tire supporting device. Specifically, the swing frame serves as a support and moving platform of the labeling assembly 40, and the rotatable connection with the base 10 enables the swing frame to approach or move away from the tire blank 50 according to the requirements of labeling and avoiding, thereby performing labeling operation or avoiding other mechanisms. The barcode stripping module is responsible for stripping a single label from the label tape, preparing for labeling. The stripped label is temporarily stored in the labeling module for labeling. The labeling module accurately pastes the stripped label on the specified position of the tire blank 50, and can accurately paste the label on the predetermined circumferential fixed angle according to the rotation angle and position of the tire blank 50. The labeling module can adopt a micro-cylinder or electromagnetic drive for pasting execution mechanism, which not only has fast response speed, but also can accurately control the pressure during labeling, thereby ensuring that the label is firmly pasted without damaging the tire blank 50. The code reading module is responsible for reading and verifying the accuracy of the label information after the label is pasted. The code reading module can be equipped with a high-resolution camera and an image processing unit, thereby quickly identifying and reading the pasted barcode information. The barcode stripping module, the labeling module, and the code reading module on the swing frame rotate synchronously, thereby ensuring that the modules can maintain a relatively stable position when the labeling assembly 40 approaches the tire blank 50 for labeling operation, avoiding labeling errors caused by position changes. At the same time, the synchronous movement between the modules of the labeling assembly 40 also allows the modules to quickly avoid after the labeling operation is completed, thereby providing space for subsequent processing of the tire blank 50, such as weighing and moving, thereby ensuring the continuous operation of each link.

[0032] In the embodiment, the supporting assembly 30 further has a tire repairing position between the weighing position and the tire supporting position. When the supporting assembly 30 is located at the tire repairing position, the positions of the tire supporting rollers 31 are closer to the axis of the tire blank 50 than at the tire supporting position, and are farther away from the axis of the tire blank 50 than at the weighing position. In this way, the tire repairing position can provide necessary space and time for the inspection and fine adjustment of the tire blank 50, thereby improving the flexibility of the production process. Specifically, when the supporting assembly 30 moves from the tire supporting position to the weighing position, it sequentially passes through the tire supporting position, the tire repairing position, and the weighing position. Thus, when the tire blank 50 is located at the tire repairing position, the tire blank 50 is hung on the two upper tire supporting rollers 31, without directly contacting and pressing the weighing assembly 20, and allowing the tire blank 50 to have a small moving space, thereby providing necessary inspection and repair space for the operator, thereby facilitating the inspection efficiency of the operator.

[0033] The base 10 of the embodiment is also provided with a center shaft, which is a central component of the whole tire supporting device, provides a platform for the mounting and operation of the labeling assembly 40, the weighing assembly 20, etc., and ensures the stability of the tire supporting device during the processing of the tire blank 50. The center shaft and the tire supporting rollers 31 are arranged on the same side of the base 10, the length direction of the center shaft is arranged along the axial direction of the tire blank 50, and the center shaft is arranged on the center axis of the tire blank 50.

[0034] The embodiment also provides a building machine, which comprises a frame and the above-mentioned tire supporting device. The tire supporting device is movably arranged on the frame, so that the tire supporting device can drive the tire blank 50 to move, thereby improving the flexibility of the tire supporting device. Specifically, in cooperation with other mechanisms of the building machine, the tire supporting device and the frame can realize horizontal movement, lifting and overturning actions, so that the tire blank 50 can be placed in a designated position.

[0035] The embodiment cancels the traditional ground weighing device by realizing online weighing, thereby improving the weighing efficiency and reducing the cost. Moreover, the traditional weighing device occupies the operation space in front of the building machine. The online weighing of the embodiment is more convenient to operate. The labeling device is integrated on the tire supporting device, and the labeling is performed when the tire blank has not left the transfer device of the building machine, thereby ensuring the labeling accuracy, saving the labeling time, freeing up the space in front of the main machine, and facilitating the operation. In this way, the weighing assembly 20 and the labeling assembly 40 are integrated on the tire supporting device, thereby realizing the rapid online weighing and fixed-point labeling of the tire blank 50, thereby saving the space, which is conducive to the layout of the building machine, and improving the work efficiency.

[0036] The use process of the tire supporting device of the embodiment is as follows: the tire supporting device waits for the tire blank 50 to be formed; the transfer device of the building machine transports the tire blank 50 to the position of the tire supporting device; the tire supporting rollers 31 expand along the radial direction of the tire blank 50 to the tire supporting position, and the tire blank 50 is taken; at the same time, the labeling device rotates to paste the label on the designated position of the tire blank 50, and reads the label information; the building machine releases the tire blank 50, and the tire supporting device carries the tire blank 50 to move to the tire repairing position for the operator to check the tire blank 50; at the same time, the four tire supporting rollers 31 contract along the radial direction of the tire blank 50 to the weighing position, at which time the tire blank 50 is completely hung on the weighing device, and the tire blank 50 has no contact with other mechanisms; the weighing sensor of the weighing device weighs, after the weighing is completed, the four tire supporting rollers 31 expand along the radial direction of the tire blank 50 to the tire repairing position, at which time the tire blank 50 is completely separated from the weighing assembly 20, and only has contact with the upper two tire supporting rollers 31; the operator completes the check, the four tire supporting rollers 31 expand along the radial direction of the tire blank 50 to the tire supporting position, and the tire blank 50 is moved to the tire unloading tool; the tire supporting device cooperates with the external mechanism to realize horizontal movement, lifting and overturning actions, so as to place the tire blank 50 in a designated position.
