Description

Technical Field

[0001] The present application relates to the field of foaming waste treatment technologies, and particularly to an automatic material discharging and clamping device. Background Art

[0002] In the steering wheel foaming industry, during the foaming process, in order to ensure the integrity of the steering wheel during foaming and molding, exhaust holes are opened on the mold. During the foaming process, after the material fills the entire mold, part of the material will be discharged along the exhaust holes to form waste. After each foaming is completed, the waste needs to be clamped out to ensure the smoothness of the exhaust holes and avoid unqualified products caused by poor material flow during the next foaming process.

[0003] However, during the waste treatment process, related equipment usually divides the feeding and discharging and clamping into two independent processes and uses independent mechanisms and driving methods respectively. This leads to the complication and enlargement of the equipment structure. For some exhaust holes with a narrow position, it may be difficult to enter and process, and the maintenance of the equipment will be relatively troublesome. Utility Model Content

[0004] In order to optimize the waste clamping, feeding and discharging equipment, streamline the structure and reduce the volume, the present application provides an automatic material discharging and clamping device.

[0005] An automatic material discharging and clamping device provided by the present application adopts the following technical solutions:

[0006] An automatic material discharging and clamping device includes:

[0007] A power source;

[0008] Claw jaws, the claw jaws include a first clamping member and a second clamping member, and the first clamping member and the second clamping member are rotationally connected through a pivot;

[0009] A connection assembly, the power source is in transmission connection with the claw jaws through the connection assembly for driving the claw jaws to move forward and backward along a first direction;

[0010] A stop pin, the stop pin is arranged in the first direction and is adapted to abut against the first clamping member and the second clamping member.

[0011] By adopting the above technical solution, the jaw is connected by a pivot between a first clamping member and a second clamping member, and is drivingly connected to the jaw by a power source through a connecting assembly, enabling the jaw to perform feeding and discharging movements in a first direction. The stop pin is provided in the first direction. When the jaw contacts the stop pin, the jaw stops feeding, and the connecting assembly continues to transmit power, driving the first clamping member and the second clamping member of the jaw to change from a closed state to an open state, starting the clamping process. When the power source drives the jaw to retract through the connecting assembly, first the jaw changes from the open state to the closed state, and then the discharging movement is performed. The feeding / discharging and clamping processes share a set of power source and connecting assembly, closely connecting the two processes, simplifying the structure, saving space, enabling the device to work in a narrow exhaust hole, and improving the adaptability and operability of the device.

[0012] Optionally, a receiving groove is formed on the opposite sides of the first clamping member and the second clamping member, and the receiving groove is located at the front end of the pivot and is adapted to receive the stop pin.

[0013] By adopting the above technical solution, the receiving groove at the front end of the pivot can receive the stop pin, reserving a moving space for the clamping movement of the jaw and reducing the influence of the stop pin on the closing during the clamping movement of the jaw. Moreover, the receiving groove can better engage with the stop pin, facilitating the conversion between the feeding / discharging movement and the clamping movement of the jaw, and contributing to improving the reliability and stability of the device.

[0014] Optionally, the power source includes a cylinder and a push rod, the cylinder drives the push rod to move in the first direction, and the push rod is connected to the connecting assembly.

[0015] By adopting the above technical solution, with the combination of the cylinder and the push rod, the power source can provide sufficient force to drive the push rod to move in the first direction. This enables the device to quickly and stably perform the movement of the jaw, improving the response speed and efficiency of the device. The cylinder can control the speed and position of the push rod by controlling the air pressure or gas flow rate, thereby achieving precise control of the jaw and improving the accuracy and stability of clamping the waste material. And connecting the push rod to the connecting assembly forms a power transmission link. This connection method is simple and reliable, without complex transmission devices or mechanical structures, reducing the possibility of failures and maintenance.

[0016] Optionally, the connecting assembly includes a first link and a second link, the first link and the second link are respectively connected to the tail ends of the first clamping member and the second clamping member, and are commonly connected to the push rod.

[0017] By adopting the above technical solution, the push rod drives the jaw to perform a feeding motion through the connecting component. When the jaw touches the stop pin, the jaw cannot move forward any further. The push rod pushes the first connecting rod and the second connecting rod to squeeze the jaw on both sides, driving the first clamping member and the second clamping member of the jaw to change from the closed state to the open state for clamping motion. By adjusting the lengths of the first connecting rod and the second connecting rod or the positions of the connection points, the relative positions between the clamping members and the magnitude of the clamping force can be changed. This enables the device to adapt to waste materials of different sizes or shapes and perform precise adjustment and control.

[0018] Optionally, the cylinder is equipped with a magnetic switch, and the system can alarm when the tooling stops at an abnormal position.

[0019] By adopting the above technical solution, a magnetic switch is installed on the cylinder and connected to the system, enabling the monitoring and detection of the tooling position. If the tooling is in an abnormal position, such as offset, misalignment, or abnormal state, the magnetic switch will detect this change and send a signal to the system. The system can trigger an alarm based on the received signal, alerting the operator or other relevant personnel of the problem and prompting them to take appropriate measures for handling. This can help promptly detect and resolve tooling position anomalies, improving the reliability and safety of the system.

[0020] Optionally, it further includes a housing that houses the power source, the jaw, and the connecting component, and is provided with an opening for the jaw to extend out.

[0021] By adopting the above technical solution, due to the certain adhesiveness of the foamed waste material, it may adhere to the jaw. The waste material accumulated on the jaw may affect the movement and clamping effect of the jaw. If the waste material is not cleaned in time, it may cause problems such as jaw jamming, reduced clamping force, or inaccurate clamping position, thereby affecting work efficiency and product quality. By setting an opening in the housing and utilizing the movement when the jaw retracts, the waste material on the jaw can be scraped off. This can avoid the accumulation and build-up of waste material, keep the jaw clean, and reduce interference with subsequent operations.

[0022] Optionally, the housing is provided with cylinder holders at both ends of the cylinder for fixing the cylinder.

[0023] By adopting the above technical solution, the cylinder generates a large amount of force and vibration during operation. By setting cylinder holders on the housing, the cylinder can be firmly fixed in position, preventing unnecessary movement or oscillation during operation. This can ensure the stability and reliability of the cylinder. Moreover, the cylinder holders on the housing provide a convenient fixing point, making the installation and maintenance of the cylinder simpler and more convenient. The operator can easily install the cylinder onto the holder and perform maintenance or replacement when needed. This can save time and labor costs and improve the maintainability of the system.

[0024] Optionally, a limiting sleeve is further arranged inside the housing, and the limiting sleeve is arranged around the push rod.

[0025] By adopting the above technical solution, the existence of the limiting sleeve can limit the stroke range of the push rod, ensure that the push rod does not exceed the predetermined stroke range during operation, ensure that the push rod is in the correct position, and enable the movement or operation of the system to meet the expected requirements. Thereby protecting the safety and stability of the system.

[0026] Optionally, a serrated microstructure is arranged at the opening of the housing.

[0027] By adopting the above technical solution, when the jaw retracts, it is necessary to scrape off the waste adhered to the jaw. The shape and sharp edges of the microstructure can effectively scrape or remove the residues on the surface of the jaw, such as adhered fragments, dust or other waste materials. This helps to keep the surface of the jaw clean and ensures that the jaw can work properly during the next use.

[0028] Optionally, a fixed connecting piece is arranged at the tail of the housing for the installation and fixation of the automatic unloading and clamping device.

[0029] By adopting the above technical solution, arranging a fixed connecting piece at the tail of the housing can provide a stable installation point for installing and fixing the automatic unloading and clamping device. It can ensure that the device is firmly connected to the housing, reducing the risk of its movement or loosening. A stable installation is very important for the normal operation of the device and the accurate execution of the clamping operation.

[0030] In summary, the present application includes at least one of the following beneficial technical effects:

[0031] 1. Driving the jaw to feed in the first direction through a power source, and realizing the conversion between the feeding and discharging movement and the clamping movement of the jaw through the stop pin and the connecting component, so as to achieve the effects of streamlining the device structure and saving space;

[0032] 2. Scraping off the waste adhered to the jaw when the jaw retracts through the opening of the housing, so as to prevent the waste from affecting the movement and clamping of the jaw;

[0033] 3. Reducing the influence of the stop pin on the closing during the clamping movement of the jaw by arranging the accommodating groove, facilitating the engagement of the stop pin, and helping to improve the reliability and stability of the device. Description of the Drawings

[0039] The following further describes the present application in detail with reference to all the drawings.

[0040] The embodiment of the present application discloses an automatic material discharging and clamping device.

[0041] Referring to Figure 1 , an automatic material discharging and clamping device includes a housing 5, a power source 1 and a claw 2. The power source 1 and the claw 2 are placed inside the housing 5, enabling the entire device to complete its functions in a compact structure. An opening 51 is designed at the lower end of the housing 5 for the extension and retraction of the claw 2, thereby realizing the effective processing of the material to be clamped.

[0042] In order to further improve the stability and reliability of the device, a fixed connecting piece 55 is provided at the upper end of the housing 5. The fixed connecting piece 55 not only provides a firm connection point but also provides an ideal support for the installation and fixation of the automatic material discharging and clamping device. It ensures the tight connection of the device and reduces the potential risks caused by movement or loosening. The stable connection can not only effectively prevent unnecessary vibration and displacement but also ensure the accuracy and controllability of the clamping action, providing a solid foundation for its reliable and efficient operation.

[0043] Referring to Figure 2 , where the B direction is the first direction, that is, the feeding and discharging direction of the claw 2. The power source 1 includes a cylinder 11 and a push rod 12. The cylinder 11 is fastened to the housing 5 through a cylinder clamping seat 52. The cylinder clamping seats 52 are arranged at both ends of the cylinder 11, effectively preventing the cylinder 11 from moving or swinging unnecessarily during operation, thereby ensuring the stability of the system.

[0044] In addition, the cylinder 11 is also equipped with a magnetic switch 13 for monitoring and detecting the position of the tooling. When the tooling is detected to be in an abnormal position, such as offset, misalignment or abnormal state, the magnetic switch 13 can detect this change and send a signal to the system to notify the operator or other relevant personnel of the problem and prompt them to take appropriate measures to handle it, improving the overall reliability and safety of the system.

[0045] As a driving device, the cylinder 11 can provide sufficient force to drive the push rod 12 to move orderly in the first direction. In order to ensure that the movement of the push rod 12 is within a controlled range, a limit sleeve 53 is provided around it. The presence of the limit sleeve 53 can effectively limit the stroke range of the push rod 12, preventing it from exceeding the predetermined stroke range during operation, thus ensuring that the push rod 12 is in the correct position and ensuring that the movement or operation of the system meets the expected requirements. In this way, the safety and stability of the system are effectively protected.

[0046] Reference Figure 3 , the end of the push rod 12 is connected to the connecting component 3. The connecting component 3 includes a first connecting rod 31 and a second connecting rod 32, and the clamping jaw 2 has a first clamping member 21 and a second clamping member 22, which are rotatably connected by a pivot 23. One end of the first connecting rod 31 is connected to the first clamping member 21, and the other end is connected to the push rod 12; one end of the second connecting rod 32 is connected to the second clamping member 22, and the other end is also connected to the push rod 12. And a stop pin 4 is provided in the first direction of the clamping jaw 2.

[0047] The push rod 12 drives the clamping jaw 2 to perform a feeding movement through the connecting component 3. When the clamping jaw 2 abuts against the stop pin 4, the clamping jaw 2 cannot move forward. At this time, the push rod 12 pushes the first connecting rod 31 and the second connecting rod 32 to squeeze the clamping jaw 2 on both sides, causing the first clamping member 21 and the second clamping member 22 of the clamping jaw 2 to change from the closed state to the open state, realizing the clamping movement. By adjusting the lengths of the first connecting rod 31 and the second connecting rod 32 or the positions of the connection points, the relative positions between the clamping members and the magnitude of the clamping force can be changed, enabling the device to adapt to waste materials of different sizes or shapes and having precise adjustment and control functions.

[0048] By integrating the designs of the cylinder 11, the push rod 12, the limit sleeve 53 and the connecting component 3, the automatic unloading and clamping device realizes safe, stable and flexible operation during the working process, and at the same time has high adaptability to waste materials of different sizes or shapes, enabling the system to accurately perform clamping and handling operations in a complex working environment.

[0049] At the front end of the pivot 23, a receiving groove 24 is designed on the opposite side of the first clamping member 21 and the second clamping member 22. The receiving groove 24 exists to accommodate the stop pin 4, thereby leaving a flexible activity space for the clamping movement of the clamping jaw 2, reducing the influence of the stop pin 4 on the closing of the clamping jaw 2 during the clamping movement, thereby ensuring that the clamping jaw 2 can be closed freely and smoothly during the clamping movement. The receiving groove 24 not only helps to reduce the interference of the stop pin 4 on the clamping movement, but also can better engage the stop pin 4. It makes the conversion of the clamping jaw 2 between the feeding and withdrawing movement and the clamping movement more convenient and smooth.

[0050] Since the foamed waste has a certain degree of adhesion, there is a possibility that it may adhere to the jaw 2. The waste accumulated on the surface of the jaw 2 may have a negative impact on the movement and clamping effect of the jaw 2. If the waste is not cleaned up in time, it may cause the jaw 2 to get stuck, the clamping force to decrease, or the clamping position to be inaccurate, thereby affecting work efficiency and product quality. Therefore, when the jaw 2 is retracted, measures need to be taken to scrape off the waste attached to the surface of the jaw 2.

[0051] To this end, the device is provided with a sawtooth-shaped microstructure 54 at the opening 51 of the housing 5. The shape and sharp edges of these microstructures 54 are designed to effectively scrape or remove the residue on the surface of the clamping jaw 2, maintain the clean state of the clamping jaw 2, and ensure that the clamping jaw 2 can work normally when it is used next time. It plays a positive role in maintaining the performance of the clamping jaw 2, maintaining work efficiency and product quality.

[0052] The implementation principle of an automatic material removal and clamping device in the embodiment of the present application is as follows:

[0053] In the embodiment of the present application, the clamping jaw 2 realizes orderly feeding motion in the first direction through precise control of a power source 1. The power source 1 realizes transmission connection with the clamping jaw 2 through the connecting assembly 3, and the stop pin 4 is set in the first direction, realizing the conversion between the feeding and withdrawing motion of the clamping jaw 2 and the clamping motion. The design of sharing a set of power source 1 and connecting assembly 3 not only simplifies the structure of the entire device and reduces the number of parts, but also effectively saves space, so that the equipment can work efficiently in a narrow exhaust hole.

[0054] Secondly, in order to reduce the influence of the stop pin 4 on the closing of the clamping movement, the embodiment of the present application provides a receiving groove 24 at the front end of the pivot 23 to reserve space for the clamping movement of the clamping jaw 2, which helps to reduce the obstruction of the stop pin 4 to the clamping movement, facilitates the engagement of the stop pin 4, and thus improves the reliability and stability of the device. The presence of the receiving groove 24 enables the clamping jaw 2 to close more flexibly during the clamping movement, ensuring the smooth progress of the clamping process.

[0055] Finally, when the jaw 2 retracts, by providing a serrated microstructure 54 at the opening 51 of the housing 5, active cleaning of the waste adhered to the surface of the jaw 2 is achieved. This prevents the accumulation of waste on the jaw 2, which may affect the movement and clamping effect of the jaw 2. By scraping off the waste adhered to the jaw 2, the device can keep the surface of the jaw 2 clean, ensuring that the jaw 2 can work properly during the next use. This active cleaning mechanism not only improves the performance of the jaw 2 but also helps to maintain the long-term reliable operation of the device.

[0056] The above are all the preferred embodiments of this application. The protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
