Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of foam plastic machinery, and particularly relates to a foam plastic machinery. BACKGROUND

[0002] Most of the existing foam plastic machines are composed of upper molds and lower molds. After the upper mold and the lower mold are closed, the foam plastic forms a foam plastic product. After the foam plastic machine completes the molding of the foam plastic product, the foam plastic product needs to be taken out, and the residual water on the foam plastic product is removed and then uniformly placed. However, the existing stage is manually taken out and poured to complete the uniform placement. However, the temperature of the foam plastic product is relatively high after the foam plastic molding, and the foam plastic product will be sprayed with water for cooling treatment after being opened. The manual taking out and pouring to complete the uniform placement is relatively dangerous, and the taking out after cooling will greatly affect the production efficiency of the foam plastic machine.

[0003] Patent No. CN110962277A discloses a foam plastic product automatic extraction mechanical hand of a foam plastic machine, which comprises a base and a support. A double-shaft walking mechanical hand capable of moving in the horizontal and vertical directions is fixedly arranged on the support. A turnover plate is hingedly connected to the bottom of the mechanical hand. A telescopic cylinder is fixedly connected to the bottom of the mechanical hand. The center of the bottom of the mechanical hand is hingedly connected to the turnover plate. The side end of the turnover plate is hingedly connected to the output end of the telescopic cylinder. A taking-out rack is fixedly connected to the end of the turnover plate. Multiple rows of suction discs are uniformly arranged on the taking-out rack. A vacuum generator is fixedly connected to the support. One end of the vacuum generator is connected to the multiple rows of suction discs through air pipes. The other end of the vacuum generator is connected to an air source.

[0004] The above patent uses a mechanical hand to cooperate with a taking-out rack to take out the foam plastic product and pour it to complete the uniform placement. However, the turnover is completed by the cooperation of the telescopic cylinder and the turnover plate during pouring. Although the turnover effect can be achieved, the structure is not stable enough, and the turnover angle is not limited, which may deviate during turnover. Therefore, improvement is needed. Utility model content

[0005] The application aims to provide a foam plastic machinery that can solve the above problems.

[0006] The application aims to provide a foam plastic machinery, which comprises an upper mold, a lower mold, a base, a rack arranged on the base, and a grabbing device arranged on the rack and capable of moving on the rack. The grabbing device comprises:

[0007] An adsorption mechanism for adsorbing the foam plastic product;

[0008] A turnover mechanism connected to the adsorption mechanism and used for driving the adsorption mechanism to turn over;

[0009] Further comprising a limiting mechanism arranged on the turnover mechanism and used for limiting the rotation angle of the turnover mechanism.

[0010] The adsorption mechanism is used for adsorbing the foam plastic product, ensuring that the foam plastic product can be stably grabbed and released during grabbing and pouring. The turnover mechanism is connected with the adsorption mechanism and is used for driving the adsorption mechanism to turn over, so as to realize the pouring action of the foam plastic product. The limiting mechanism is arranged on the turnover mechanism and is used for limiting the rotation angle of the turnover mechanism, so as to ensure that the turnover action is performed within a predetermined angle range, prevent deviation during the turnover process, and improve the stability and accuracy of the turnover.

[0011] By designing the cooperation of the turnover mechanism and the limiting mechanism, the foam plastic machine of the present application can maintain higher stability during the turnover process. The limiting mechanism can ensure that the turnover mechanism works within a predetermined angle range, avoiding product damage caused by too large or too small turnover angles. The design of the limiting mechanism precisely controls the turnover angle, which not only improves the accuracy of the foam plastic product pouring, but also reduces repeated operations and time waste caused by turnover deviation.

[0012] Further, the turnover mechanism comprises:

[0013] The driver is used for providing power in a straight line;

[0014] The rotating assembly is connected with the adsorption mechanism and is used for converting the linear motion of the driver into rotation;

[0015] The fixed frame is further included, and the non-output end of the driver is hinged to the fixed frame, and the rotating assembly is installed on the fixed frame.

[0016] The driver is used for providing power in a straight line, which is used to drive the movement of the turnover mechanism. The driver here can adopt a linear motion actuator such as a pneumatic cylinder, a hydraulic cylinder or an electric push rod. The rotating assembly is used to convert the linear motion of the driver into rotation, so as to drive the adsorption mechanism to turn over. The rotating assembly is connected with the adsorption mechanism, ensuring that the adsorption mechanism can be stably driven to move during the turnover process. The fixed frame provides support and fixing effect, ensuring that the turnover mechanism can be stably installed on the rack. The non-output end of the driver is hinged to the fixed frame, allowing the driver to swing or rotate on the fixed frame, thereby realizing the turnover action. At the same time, the rotating assembly is also installed on the fixed frame, ensuring the stability and reliability of the entire turnover mechanism.

[0017] When the driver receives the control signal, it begins to generate a straight-line thrust. This thrust is converted into a rotating action through the rotating assembly, thereby driving the adsorption mechanism to flip over. Since the driver is hinged to the fixed frame, the flipping action can be performed within a certain angle range. At the same time, the limiting mechanism will ensure that the flipping angle does not exceed the predetermined range, thereby preventing mechanical failure or product damage. The flipping mechanism, through the ingenious cooperation of the driver, rotating assembly and fixed frame, realizes a compact design, which helps to reduce the space occupied by the machine and improve the integration and flexibility of the entire bubble plastic machine. And because of the use of hinged and fixed frame design, the flipping mechanism can maintain high stability during the flipping process, which helps to reduce mechanical vibration and noise, and improve the accuracy and reliability of the flipping action.

[0018] Further: the rotating assembly comprises:

[0019] The connecting frame is arranged at the bottom of the fixed frame;

[0020] The first gear is rotatably arranged in the connecting frame;

[0021] The second gear is arranged in the connecting frame and engaged with the first gear;

[0022] Wherein, the second gear is located directly above the first gear, and the output end of the driver is connected with the eccentric position of the second gear.

[0023] The connecting frame, as the support structure of the entire rotating assembly, is arranged at the bottom of the fixed frame, providing a platform for mounting and fixing the first gear and the second gear. The first gear is rotatably arranged in the connecting frame, and transmits motion and torque through engagement with the second gear. The second gear is arranged in the connecting frame and engaged with the first gear, located directly above the first gear, as the part directly connected with the output end of the driver, and the diameter of the second gear is greater than that of the first gear to meet the speed and torque requirements of the output end of the driver. The output end of the driver is connected with the eccentric position of the second gear, so that when the driver generates a straight-line thrust, it can push the second gear to rotate around its center point. Since the second gear is engaged with the first gear, the first gear will also rotate, thereby driving the entire flipping mechanism to flip over.

[0024] When the driver receives the control signal and starts to generate a straight-line thrust, this thrust is transmitted to the second gear through the eccentric connection. Since the second gear is in mesh with the first gear, the rotation of the second gear will drive the first gear to rotate. This rotational motion is transmitted to the suction mechanism through the connecting frame and the connecting part of the suction mechanism, thereby realizing the overturning of the foam product. The gear transmission has the characteristics of smooth transmission and low noise, which helps to reduce vibration and noise during overturning and improves the accuracy and reliability of the overturning action. At the same time, by adjusting the number of teeth and the module of the gear, as well as the parameters of the driver, different shapes and sizes of foam products can be flexibly adapted to meet various production needs.

[0025] Further, the limiting mechanism includes a through slot provided on the connecting frame, the through slot is arc-shaped, and the output end of the driver and the eccentric position of the second gear are connected by a connecting rod, the connecting rod passes through the through slot.

[0026] The limiting mechanism is responsible for limiting the angle range of the overturning action, thereby ensuring the stability and accuracy of the overturning process, mainly composed of a through slot provided on the connecting frame, a connecting rod, and an eccentric connection between the driver and the second gear. The through slot is provided on the connecting frame and is arc-shaped, allowing the connecting rod to move along a predetermined path during the overturning process, thereby limiting the range of overturning angle. The connecting rod is used to connect the output end of the driver and the eccentric position of the second gear, which passes through the through slot and moves within the through slot as the overturning action proceeds. When the driver receives the control signal and starts to generate a straight-line thrust, this thrust is transmitted to the second gear through the eccentric connection, causing the second gear to rotate around its center point. Since the connecting rod passes through the through slot and is eccentrically connected to the second gear, as the overturning action proceeds, the connecting rod will move along a predetermined arc-shaped path within the through slot. When the overturning angle reaches the end of the through slot, the connecting rod will be limited by the through slot and cannot continue to move, thereby limiting the overturning angle.

[0027] The limiting mechanism achieves simple and effective limitation of the overturning angle through the design of the through slot, the connecting rod, and the eccentric connection. Due to the cooperation of the through slot and the connecting rod, the overturning process can proceed smoothly within the predetermined angle range, avoiding product damage caused by excessive or insufficient overturning angle.

[0028] Further, the suction mechanism includes a suction plate, a suction cup provided on the suction plate, and a vacuum generator provided on the frame, the vacuum generator is connected to the suction cup through an air pipe, and the vacuum generator is connected to an air source.

[0029] The adsorption plate serves as a support structure for the adsorption mechanism, ensuring the installation of the suction cups and the stable installation of the entire adsorption mechanism on the rack. The suction cups grab and fix the foam products by contacting the surface of the foam products and generating negative pressure, and the inside is provided with a channel for connecting the air pipe and the vacuum generator. The vacuum generator is connected to the suction cups through the air pipe to provide the required negative pressure environment for the suction cups.

[0030] When the foam machine needs to grab the foam products, the vacuum generator starts working and generates negative pressure, which is transmitted to the suction cups through the air pipe, forming a low-pressure area inside the suction cups. Because there is a certain contact area and sealing between the surface of the foam products and the suction cups, the foam products will be adsorbed on the suction cups. When the foam products need to be released, the vacuum generator stops working, and the negative pressure inside the suction cups disappears, and the foam products will fall off due to gravity or other external forces. By controlling the start and stop of the vacuum generator, the grabbing and releasing operations of the foam products can be easily realized without complex mechanical transmission or manual intervention. The production efficiency and automation degree of the machine are improved, and the difficulty and cost of manual operation are also reduced.

[0031] Further, the suction cups are provided in plurality, and the plurality of suction cups are uniformly distributed on the adsorption plate.

[0032] In order to enhance the adsorption effect, the suction cups are provided in plurality and uniformly distributed on the adsorption plate, which can ensure that the adsorption mechanism can provide uniform adsorption force when grabbing the foam products, avoiding damage or falling of the products due to uneven force. At the same time, through the uniform distribution of the plurality of suction cups and the negative pressure action of the vacuum generator, the adsorption mechanism can provide strong grabbing force to ensure that the foam products will not fall off or be damaged during the turning and moving process.

[0033] The beneficial effects of the present application are:

[0034] 1. By designing the cooperation of the turning mechanism and the limiting mechanism, the foam machine of the present application can maintain higher stability during turning, and the limiting mechanism can ensure that the turning mechanism works within the predetermined angle range, avoiding damage to the products due to too large or too small turning angle;

[0035] 2. The design of the limiting mechanism enables precise control of the turning angle, which not only improves the accuracy of the foam product pouring, but also reduces the repeated operation and time waste caused by turning deviation;

[0036] 3. The turning mechanism realizes compact design through the ingenious cooperation of the driver, the rotating assembly and the fixed frame, which helps to reduce the space occupied by the machine and improve the integration and flexibility of the entire foam machine. And because of the design of the hinge and the fixed frame, the turning mechanism can maintain high stability during turning, which helps to reduce mechanical vibration and noise, and improves the accuracy and reliability of the turning action.

[0047] an adsorption mechanism 300 for adsorbing the foam plastic product;

[0048] a turnover mechanism 400 connected with the adsorption mechanism 300 and used for driving the adsorption mechanism 300 to turn over;

[0049] wherein, a limiting mechanism 500 is arranged on the turnover mechanism 400 and used for limiting the rotation angle of the turnover mechanism 400.

[0050] In some embodiments of the embodiment of the present application, as shown, Figure 1 the above-mentioned foam plastic machine is adopted, the adsorption mechanism 300 is used for adsorbing the foam plastic product, so as to ensure that the foam plastic product can be stably grabbed and released during the grabbing and pouring process. The turnover mechanism 400 is connected with the adsorption mechanism 300 and used for driving the adsorption mechanism 300 to turn over, so as to realize the pouring action of the foam plastic product. The limiting mechanism 500 is arranged on the turnover mechanism 400 and used for limiting the rotation angle of the turnover mechanism 400, so as to ensure that the turnover action is performed within a predetermined angle range, prevent deviation during the turnover process, and improve the stability and accuracy of the turnover.

[0051] By designing the cooperation of the turnover mechanism 400 and the limiting mechanism 500, the foam plastic machine of the present application can maintain higher stability during the turnover process. The limiting mechanism 500 can ensure that the turnover mechanism 400 works within a predetermined angle range, avoiding product damage caused by too large or too small turnover angles. The design of the limiting mechanism 500 precisely controls the turnover angle, which not only improves the accuracy of the foam plastic product pouring, but also reduces repeated operations and time waste caused by turnover deviation.

[0052] Embodiment 2:

[0053] The embodiment of the present application provides a foam plastic machine, which comprises the above technical features, and further comprises the following technical features.

[0054] As shown, the turnover mechanism 400 comprises:

[0055] a driver 410 for providing power in a straight line;

[0056] a rotating assembly 420 connected with the adsorption mechanism 300 and used for converting the linear motion of the driver 410 into rotation;

[0057] The non-output end of the driver 410 is hinged to the fixed frame 430, and the rotating assembly 420 is installed on the fixed frame 430.

[0058] In the embodiment of the application, the driver 410 is used to provide linear power for driving the movement of the turnover mechanism 400. The driver 410 herein can adopt a linear motion actuator such as a pneumatic cylinder, a hydraulic cylinder or an electric push rod. The rotating assembly 420 is used to convert the linear motion of the driver 410 into rotation, thereby driving the adsorption mechanism 300 to turn over. The rotating assembly 420 is connected with the adsorption mechanism 300, ensuring that the adsorption mechanism 300 can be stably driven to move during the turnover process. The fixed frame 430 provides support and fixing functions, ensuring that the turnover mechanism 400 can be stably installed on the rack 210. The non-output end of the driver 410 is hinged to the fixed frame 430, allowing the driver 410 to swing or rotate on the fixed frame 430, thereby realizing the turnover action. At the same time, the rotating assembly 420 is also installed on the fixed frame 430, ensuring the stability and reliability of the entire turnover mechanism 400.

[0059] When the driver 410 receives a control signal, it starts to generate a linear thrust. This thrust is converted into a rotating action by the rotating assembly 420, thereby driving the adsorption mechanism 300 to turn over. Since the driver 410 is hinged to the fixed frame 430, the turnover action can be performed within a certain angle range. At the same time, the limiting mechanism 500 will ensure that the turnover angle does not exceed the predetermined range, thereby preventing mechanical failure or product damage. The turnover mechanism 400 realizes a compact design through the ingenious cooperation of the driver 410, the rotating assembly 420 and the fixed frame 430, which helps to reduce the space occupied by the machine and improve the integration and flexibility of the entire bubble plastic machine. And because of the hinge and fixed frame 430 design, the turnover mechanism 400 can maintain high stability during the turnover process, which helps to reduce mechanical vibration and noise, and improves the accuracy and reliability of the turnover action.

[0060] Embodiment 3:

[0062] As shown in the figure, the rotating assembly 420 includes:

[0063] The connecting frame 421 is arranged at the bottom of the fixed frame 430;

[0064] The first gear 422 is rotatably arranged in the connecting frame 421;

[0065] The second gear 423 is arranged in the connecting frame 421 and meshes with the first gear 422;

[0066] The second gear 423 is located directly above the first gear 422, and the output end of the driver 410 is connected to the eccentric position of the second gear 423.

[0067] In the embodiment of the present application, the connecting frame 421 serves as the support structure of the entire rotating assembly 420 and is arranged at the bottom of the fixed frame 430 to provide a platform for mounting and fixing the first gear 422 and the second gear 423. The first gear 422 is rotatably arranged in the connecting frame 421 and transmits motion and torque through meshing with the second gear 423. The second gear 423 is arranged in the connecting frame 421 and meshes with the first gear 422, located directly above the first gear 422. The second gear 423 is directly connected to the output end of the driver 410, and the diameter of the second gear 423 is greater than that of the first gear 422 to meet the requirements of the rotational speed and torque of the output end of the driver 410. The output end of the driver 410 is connected to the eccentric position of the second gear 423, so that when the driver 410 generates a linear thrust, it can push the second gear 423 to rotate around its center point. Since the second gear 423 meshes with the first gear 422, the first gear 422 will also rotate, thereby driving the entire turnover mechanism 400 to turn over.

[0068] When the driver 410 receives the control signal and starts to generate a linear thrust, this thrust is transmitted to the second gear 423 through eccentric connection. Since the second gear 423 meshes with the first gear 422, the rotation of the second gear 423 will drive the first gear 422 to rotate. This rotational motion is transmitted to the adsorption mechanism 300 through the connecting part of the connecting frame 421 and the adsorption mechanism 300, thereby realizing the turnover of the foam product. Gear transmission has the characteristics of smooth transmission and low noise, which helps to reduce vibration and noise during turnover and improves the accuracy and reliability of the turnover action. At the same time, by adjusting the number of teeth and the module of the gear, as well as the parameters of the driver 410, different shapes and sizes of foam products can be flexibly adapted to meet various production needs.

[0071] As shown in the figure, the limiting mechanism 500 comprises a through slot 510 arranged on the connecting frame 421, the through slot 510 is arc-shaped, and the output end of the driver 410 is connected to the eccentric position of the second gear 423 through a connecting rod 520, the connecting rod 520 passes through the through slot 510.

[0072] In the embodiment of the present application, the limiting mechanism 500 is responsible for limiting the angle range of the turnover action, thereby ensuring the stability and accuracy of the turnover process, mainly composed of a through slot 510 provided on the connecting frame 421, a connecting rod 520, and an eccentric connection of the driver 410 and the second gear 423. The through slot 510 is provided on the connecting frame 421 and is arc-shaped, allowing the connecting rod 520 to move along a predetermined path during the turnover process, thereby limiting the range of the turnover angle. The connecting rod 520 is used to connect the output end of the driver 410 and the eccentric position of the second gear 423, which passes through the through slot 510. As the turnover action proceeds, the connecting rod 520 will move within the through slot 510. When the driver 410 receives the control signal and starts to generate a linear thrust, this thrust is transmitted to the second gear 423 through the eccentric connection, causing the second gear 423 to rotate around its center point. Since the connecting rod 520 passes through the through slot 510 and is eccentrically connected to the second gear 423, as the turnover action proceeds, the connecting rod 520 will move along a predetermined arc-shaped path within the through slot 510. When the turnover angle reaches the end of the through slot 510, the connecting rod 520 will be limited by the through slot 510 and cannot continue to move, thereby achieving the limitation of the turnover angle.

[0073] The limiting mechanism 500 achieves simple and effective limitation of the turnover angle through the design of the through slot 510, the connecting rod 520, and the eccentric connection. Due to the cooperation of the through slot 510 and the connecting rod 520, the turnover process can smoothly proceed within a predetermined angle range, avoiding product damage caused by excessive or insufficient turnover angles.

The vacuum generator 330 is connected to the suction cup 320 through the air pipe to provide the required negative pressure environment for the suction cup 320.

[0078] When the bubble plastic machine needs to grab the bubble plastic product, the vacuum generator 330 starts working and generates negative pressure, which is transmitted to the suction cup 320 through the air pipe, forming a low-pressure area inside the suction cup 320. Because there is a certain contact area and sealing between the surface of the bubble plastic product and the suction cup 320, the bubble plastic product will be adsorbed on the suction cup 320.
