Description

Technical Field

[0001] This utility model relates to the field of molding devices, and more specifically, to a material clamping device for a molding machine and a molding machine. Background Technology

[0002] Magnetic clamps are material clamping devices used in tire molding processes. During the bonding of composite parts, to prevent them from detaching from the molding drum, the clamping rod falls down to hold the material head in place when it is fed onto the drum, and then retracts after rotating one revolution with the drum. However, current magnetic clamps use a cantilever structure. During production, the locking blocks at both ends of the magnetic clamp are easily bent when the material is loaded onto the drum, leading to incorrect position recognition by the recovery device and resulting in recovery failure. Furthermore, after recovery, the locking blocks wobble within the recovery device, easily causing the limiting component to deviate from its position after falling, leading to further recovery failure. Recovery failure requires manual intervention, significantly reducing production efficiency. In severe cases, it can even damage the clamping rod, causing downtime, thus increasing production costs and wasting time. Utility Model Content

[0003] The main purpose of this utility model is to provide a material clamping device and a molding machine for a molding machine, so as to solve the problem that the clamping plate in the prior art is prone to failure to be recycled.

[0004] To achieve the above objectives, according to one aspect of the present invention, a material clamping device for a molding machine is provided, comprising a clamping plate, a transmission component, and a recycling component. The clamping plate can be attached to the surface of a drum; the transmission component is connected to a first surface of the clamping plate away from the drum, and the projection of the transmission component on the first surface is within the range of the first surface; the recycling component is movably disposed and can be docked with the transmission component, and the recycling component drives the clamping plate to be attached to or detached from the drum through the transmission component.

[0005] Furthermore, there are multiple transmission components, and transmission components are provided at both ends of the clamping plate.

[0006] Furthermore, the recycling assembly includes a recycling seat and a stop. The recycling seat has a recycling space and an opening on the side along the rotation direction of the clamping plate. The transmission component extends into the recycling space through the opening. The stop is movably disposed within the recycling space and has a stopping position and a clearance position. When the stop is in the stopping position, the transmission component extends into the recycling space and abuts against the stop. When the stop is in the clearance position, the stop avoids the transmission component, and the transmission component can pass through the recycling space.

[0007] Furthermore, the transmission component has a stop notch, and when the transmission component is in the retraction space, the stop notch abuts against the stop component, and at least a portion of the stop component is located within the stop notch.

[0008] Furthermore, the recycling assembly also includes a rotating component and an elastic component. The rotating component is located within the recycling space and is rotatably connected to the recycling seat, and can rotate in the direction in which the transmission component extends into the recycling space. The two ends of the elastic component are connected to the rotating component and the recycling seat respectively, and provide the transmission component with a spring force to move towards the stop component, so that the rotating component and the stop component together clamp the transmission component.

[0009] Furthermore, the recycling assembly also includes a limiting member, which is connected to the recycling seat and located within the recycling space. When the transmission member is located in the recycling space, the side of the transmission member away from the first surface is limited and abutted against the limiting member.

[0010] Furthermore, the recycling assembly also includes a lifting drive, which is connected to the recycling seat and drives the recycling seat to rise and fall.

[0011] Furthermore, the transmission component has a connecting part and a docking part. The connecting part is located at the end of the clamping plate that is farther away from the docking part. The connecting part is connected to the clamping plate, and the docking part can be docked with the recycling assembly.

[0012] Furthermore, the clamping device also includes a positioning detection element, which is connected to the recycling assembly and detects the position of the transmission component.

[0013] According to another aspect of the present invention, a molding machine is provided, including the above-described material clamping device for molding machines.

[0014] By applying the technical solution of this utility model, the projection of the transmission component on the first surface is positioned within the range of the first surface. When the transmission component is placed on the surface of the drum along with the clamping plate, the clamping plate adheres to the surface of the drum, and the transmission component is located on the side of the clamping plate away from the drum. This ensures that a clamping plate is positioned between the transmission component and the drum, preventing the transmission component from being suspended above the drum surface. This avoids gaps between the transmission component and the drum that could cause deformation of the transmission component and lead to recycling failure. In this way, on the one hand, when the transmission component needs to be recycled, it can be kept in the correct position, ensuring successful recycling by the recycling assembly. This improves the success rate of clamping plate recycling, reduces the frequency of clamping plate falling, and thus improves production efficiency. On the other hand, the clamping plate adheres to the drum surface, enabling precise clamping and release of materials, thereby improving processing accuracy and production efficiency.

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0023] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0024] To address the problem of easy failure to recycle clamps in existing technologies, this utility model provides a material clamping device for a molding machine and a molding machine, wherein the molding machine includes the material clamping device described below.

[0025] like Figures 1 to 3 The shown material clamping device for a molding machine includes a clamping plate 10, a transmission component 20, and a recovery component 30. The clamping plate 10 can be attached to the surface of a drum. The transmission component 20 is connected to a first surface of the clamping plate 10 away from the drum, and the projection of the transmission component 20 on the first surface is within the range of the first surface. The recovery component 30 is movably disposed and can be docked with the transmission component 20. The recovery component 30 drives the clamping plate 10 to be attached to or detached from the drum through the transmission component 20.

[0026] In this embodiment, the projection of the transmission component 20 on the first surface is positioned within the range of the first surface. This ensures that when the transmission component 20 is placed on the surface of the drum along with the clamping plate 10, the clamping plate 10 adheres to the drum surface, and the transmission component 20 is located on the side of the clamping plate 10 furthest from the drum. This arrangement ensures that the clamping plate 10 is positioned between the transmission component 20 and the drum, preventing the transmission component 20 from being suspended above the drum surface. This avoids gaps between the transmission component 20 and the drum that could cause deformation of the transmission component 20 and lead to recycling failure. Thus, on the one hand, when the transmission component 20 needs to be recycled, it remains in the correct position, ensuring successful recycling by the recycling assembly 30. This increases the success rate of recycling the clamping plate 10 and reduces the frequency of the clamping plate 10 falling, thereby improving production efficiency. On the other hand, the clamping plate 10 adheres to the drum surface, enabling precise clamping and release of materials, thereby improving processing accuracy and production efficiency.

[0027] like Figure 2 As shown, in this embodiment, there are multiple transmission components 20, and transmission components 20 are provided at both ends of the clamping plate 10, thereby ensuring successful retrieval of the clamping plate 10. Specifically, since the clamping plate 10 is attached to the circumferential side of the drum along the axial direction of the drum, and the material is located between the clamping plate 10 and the drum, the clamping plate 10 is relatively long in order to ensure effective clamping of the material. Therefore, in this embodiment, the transmission component 20 retrieval assembly 30 is set to two, and is provided at both ends of the clamping plate 10. Correspondingly, as shown... Figure 1 As shown, the material clamping device in this embodiment is equipped with two recovery components 30 to recover the transmission components 20 at both ends of the clamping plate 10. In this way, when the clamping plate 10 needs to be recovered, the two recovery components 30 work simultaneously, so that the transmission components 20 at both ends are recovered synchronously, thereby stably recovering the clamping plate 10. When the clamping plate 10 is placed on the drum, both ends of the clamping plate 10 can also be synchronously attached to the drum, thereby making the attachment of the clamping plate 10 on the drum surface more uniform. This avoids unstable material clamping or damage caused by uneven force at a single point, significantly improves the contact stability between the clamping plate 10 and the drum, and reduces the displacement and deformation of the material during the molding process.

[0028] like Figure 3As shown, in this embodiment, the recycling assembly 30 includes a recycling seat 31 and a stop 32. The recycling seat 31 has a recycling space. Along the rotation direction of the clamping plate 10, the side of the recycling seat 31 has an opening, and the transmission member 20 extends into the recycling space through the opening. The stop 32 is movably disposed within the recycling space. The stop 32 has a stopping position and a clearance position. When the stop 32 is in the stopping position, the transmission member 20 extends into the recycling space and abuts against the stop 32. When the stop 32 is in the clearance position, the stop 32 clears the transmission member 20, and the transmission member 20 can pass through the recycling space. Specifically, the recycling seat 31 in this embodiment has an upper baffle and a lower baffle arranged perpendicular to the rotation direction of the clamping plate 10, and a side plate connecting the upper baffle and the lower baffle, thereby forming the recycling space. The stop member 32 is perpendicular to the lower baffle and located above the lower baffle. When the stop member 32 is in the stop position, it abuts against the lower baffle to prevent the transmission member 20 from passing through the recovery space. When the stop member 32 is in the avoidance position, it retracts to the upper baffle to allow the transmission member 20 to pass through the recovery space. In this embodiment, the clamping plate 10 rotates synchronously with the drum, and the transmission member 20 also rotates synchronously with the clamping plate 10. The recovery seat 31 is located on the side of the clamping plate 10 away from the drum. When the clamping plate 10 needs to be recovered, the recovery seat 31 is located on the recovery path of the transmission member 20, and the stop member 32 is in the stop position, so that when the transmission member 20 rotates to the recovery position, the transmission member 20 can extend into the recovery space, and the stop member 32 prevents the transmission member 20 from continuing to rotate and pass through the recovery space. When the clamping plate 10 needs to be placed on the drum, the stop 32 is in a clearance position, allowing the transmission component 20 to rotate out of the recycling space. As the clamping plate 10 rotates, the recycling seat 31 exits the recycling path of the transmission component 20. This makes the recycling and placement process of the clamping plate 10 smoother, preventing jamming of the transmission component 20 during recycling, thus extending the service life of the material clamping device. Optionally, the stop 32 can be configured as a stop cylinder. The cylinder rod of the stop cylinder is placed perpendicular to the lower baffle and can extend into the recycling space, thereby stopping the transmission component 20.

[0029] In this embodiment, the transmission component 20 has a stop notch. When the transmission component 20 is in the recovery space, the stop notch abuts against the stop component 32, and at least a portion of the stop component 32 is located within the stop notch. This cooperation between the stop notch and the stop component 32 ensures the stable position of the transmission component 20 within the recovery space, preventing the clamping plate 10 from becoming misaligned due to the transmission component 20 shaking within the recovery space, thus avoiding failure in the next recovery attempt. Specifically, the transmission component 20 has a horizontal plate arranged radially perpendicular to the drum. The horizontal plate can extend into the recovery space to cooperate with the stop component 32. Along the rotation direction of the clamping plate 10, the horizontal plate first has a stop notch on the side closest to the stop component 32, so that after the transmission component 20 enters the recovery space, the stop notch can cooperate with the stop component 32, thereby ensuring the stability of the transmission component 20 during recovery and release. In this embodiment, the portion of the stop component 32 extending into the recovery space is cylindrical, and correspondingly, the stop notch can be semi-circular or rectangular.

[0030] In this embodiment, the recycling assembly 30 further includes a rotating member 33 and an elastic member 34. The rotating member 33 is located in the recycling space and is rotatably connected to the recycling seat 31, and can rotate in the direction in which the transmission member 20 extends into the recycling space. The two ends of the elastic member 34 are respectively connected to the rotating member 33 and the recycling seat 31, and provide the transmission member 20 with a spring force to move towards the stop member 32, so that the rotating member 33 and the stop member 32 jointly clamp the transmission member 20. In this way, the transmission member 20 can be stably clamped during the recycling process, thereby reducing the shaking and wear of the transmission member 20. Specifically, the rotating member 33 has a rotating shaft and is positioned between the upper and lower baffles of the recovery seat 31 via the rotating shaft. The rotating shaft is located at one end of the rotating member 33, and the elastic member 34 is connected to the other end of the rotating member 33. Thus, when the transmission member 20 rotates into the recovery space, the transmission member 20 collides with the rotating member 33 at the rotating shaft and slides into the recovery space. Simultaneously, the rotating member 33 returns to its original position under the action of the elastic member 34 to limit the axial movement of the clamping plate 10 along the drum. At the same time, the stop member 32 engages with the stop notch, thereby fixing the position of the transmission member 20 along the axial direction of the drum and preventing the clamping plate 10 from shaking. Optionally, the elastic member 34 can be a spring.

[0031] In this embodiment, the recycling assembly 30 further includes a limiting member 35, which is connected to the recycling seat 31 and located within the recycling space. When the transmission member 20 is located in the recycling space, the side of the transmission member 20 away from the first surface is limited and abutted against the limiting member 35, thereby preventing the transmission member 20 from swaying in the direction perpendicular to the lower baffle within the recycling space. This ensures that the positions of the transmission members 20 at both ends of the clamping plate 10 are basically consistent within the recycling space, thus ensuring that the clamping plate 10 can accurately fit against the drum when it falls. In this embodiment, the limiting member 35 is set as a rectangular block, and the distance between the side of the limiting member 35 near the lower baffle and the lower baffle is not greater than the distance between the side of the upper baffle near the lower baffle and the lower baffle. Since it is necessary to avoid the stop member 32, the upper baffle in this embodiment is smaller than the lower baffle. The setting of the limiting member 35 compensates for the inadequacy of the upper baffle in stopping the transmission member 20, thereby further improving the stability of the transmission member 20 within the recycling space.

[0032] In this embodiment, the recycling assembly 30 further includes a lifting drive 36, which is drivenly connected to the recycling seat 31 and drives the recycling seat 31 to rise and fall. This allows the recycling seat 31 to descend to the transmission component 20 when the clamping plate 10 needs to be recycled, facilitating the recycling of the transmission component 20 and the clamping plate 10. When the clamping plate 10 passes through the recycling space and needs to rotate synchronously with the drum, the lifting drive 36 drives the recycling seat 31 to rise away from the drum surface, avoiding rotation of components such as the transmission component 20 and the clamping plate 10. Simultaneously, when there are differences in drum size or material thickness, the lifting drive 36 can adjust the distance between the recycling seat 31 and the drum surface to facilitate the recycling of the transmission component 20 and the clamping plate 10. This allows the material clamping device to be used with drums of various sizes, thereby improving the flexibility and adaptability of the material clamping device. Optionally, the lifting drive 36 can be configured as a cylinder.

[0033] like Figure 2As shown, in this embodiment, the transmission component 20 has a connecting portion 21 and a docking portion 22. The connecting portion 21 is farther away from the end of the docking portion 22 from the clamping plate 10. The connecting portion 21 is connected to the clamping plate 10, and the docking portion 22 can dock with the recycling component 30 to ensure the stability of the docking portion 22 in the recycling space. Specifically, the connecting part 21 is connected to the first surface of the clamping plate 10 and is arranged perpendicular to the clamping plate 10. The docking part 22 is arranged parallel to the clamping plate 10 and is located at the end of the connecting part 21 away from the clamping plate 10. The docking part 22 extends towards the side of the connecting part 21 near the end of the clamping plate 10, but the extension length of the docking part 22 does not exceed the end of the clamping plate 10. This allows the lower baffle of the recovery seat 31 to extend between the docking part 22 and the clamping plate 10 when the recovery assembly 30 recovers the transmission member 20 and the clamping plate 10. The docking part 22 extends into the recovery space, so the lower baffle directly presses down on the clamping plate 10, and the entire clamping plate 10 is attached to the drum surface. The clamping plate 10 is not easily deformed, thus ensuring the accuracy of the recovery position and avoiding the situation where the docking part 22 is suspended above the drum surface, causing deformation when the lower baffle presses down. It should be noted that the docking part 22 is the aforementioned horizontal plate, and the stop notch is located on the docking part 22. Of course, the mating part 22 can also extend to the side of the connecting part 21 away from the end of the clamping plate 10, as long as the projection of the mating part 22 on the first surface does not exceed the range of the first surface.

[0034] In this embodiment, the material clamping device further includes a positioning detection element 40, which is connected to the recycling component 30 and detects the position of the transmission component 20. This further ensures the accuracy of the recycling position, avoids production failures caused by positional deviations, prevents false detections, and thus improves the reliability and stability of the material clamping device's operation, extending its service life. Optionally, the positioning detection element 40 can be a proximity switch.

[0035] In this embodiment, the clamping plate 10 consists of an upper clamping plate 10, a lower clamping plate 10, a conveyor belt, and a magnet. The magnet is located at the end of the clamping plate 10. When the material clamping device is in use, the clamping plate 10 and the transmission component 20 fall, the magnet is attracted to the drum, and clamps the material head. During this process, the force is entirely applied to the magnet, and the clamping plate 10 and the transmission component 20 will not undergo elastic deformation. The distance between the clamping plate 10 and the drum is ensured by the lifting drive component 36. Therefore, the lifting drive component 36 can be used for its full stroke each time it moves. When the transmission component 20 and the clamping plate 10 are retracted, the gap between the transmission component 20 and the limiting component 35 can be ensured to avoid collision. In this embodiment, when the clamping device is in use, the clamping plate 10 falls onto the drum and rotates one revolution with the drum. When it is ready for retrieval, the relative position of the clamping plate 10 and the retrieval component 30 remains basically unchanged. When the clamping plate 10 swings out, the transmission component 20 does not shake, reducing the frequency of the clamping plate 10 falling, thereby improving production efficiency.

[0036] It should be noted that "multiple" in the above embodiments refers to at least two.

[0037] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0038] 1. This solves the problem of easy failure to recycle the clamping plate in existing technologies;

[0039] 2. By setting the projection of the transmission component on the first surface to be within the range of the first surface, when the transmission component is placed on the surface of the drum together with the clamping plate, the clamping plate is attached to the surface of the drum, and the transmission component is located on the side of the clamping plate away from the drum. This ensures that there is a clamping plate between the transmission component and the drum, and the transmission component is not suspended on the surface of the drum. This avoids the situation where there is a gap between the transmission component and the drum, which would cause the transmission component to deform and cause recycling failure.

[0040] 3. On the one hand, when the transmission component needs to be recycled, it can be kept in the correct position, thereby ensuring that the recycling component can successfully recycle it, thus improving the success rate of the recycling component in recycling the clamping plate, reducing the frequency of clamping plate falling, and thus improving production efficiency. On the other hand, the clamping plate is attached to the surface of the drum to achieve precise clamping and release of materials, thereby improving processing accuracy and production efficiency.
