They are made of materials such as stainless steel, cast iron, aluminum alloy, and ceramics. Currently, metal cookware is widely used. Its production process mainly includes raw material preparation, metal cutting, stamping, welding, surface treatment, quality inspection, and other processes. Among them, the existing pot blanks need to be edge-grinded or curled after forming. The specific operation process is that the operator places the pot blank on a designated tool and drives the pot blank to rotate through a motor, so that the pot blank rotates around its own center to achieve the edge grinding or curling work. However, in the existing technology, this operation placement still has certain defects. The main reason is that the worker needs to place the pot blanks one by one on the designated tool, then clamp the pot blanks, and finally start the motor. There are problems such as cumbersome operation steps, low work efficiency, and high labor costs. Utility Model Content

[0003] In order to solve the above technical problems, the present invention provides a feeding and clamping mechanism for cookware production, which can use a conveyor belt to move the pot blank according to a specified state.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] As shown in the figure, a feeding and clamping mechanism for cookware production includes:

[0024] The conveyor belt 1 has a plurality of first through holes 11 arranged at intervals on its surface, and a plurality of upwardly protruding limiting protrusions 15 are provided on the conveyor belt 1 around each first through hole 11; in this example, the plurality of first through holes 11 are arranged at equal intervals on the surface of the conveyor belt 1, and the diameter of the first through holes 11 is smaller than the maximum outer diameter of the pot blank 10. More specifically, the pot blank 10 is placed on the conveyor belt 1 with its opening facing downward, and the maximum outer diameter of the pot blank 10 in the opening direction is larger than the diameter of the first through hole 11, so as to facilitate the pot blank 10 to not fall from the first through hole 11 after being placed on the conveyor belt 1; the limiting protrusions 15 are evenly distributed along the center of the first through hole 11, so that when the pot blank 10 is placed on the conveyor belt 1 and is located directly above the first through hole 11, the inner wall of the pot blank 10 can contact the limiting protrusion 15, thereby avoiding the problem of displacement of the pot blank 10 during the conveying process;

[0025] The workbench 2 has a second through hole 12 formed on its surface. The conveyor belt 1 is located above the workbench 2, and the first through hole 11 and the second through hole 12 can overlap with each other. In this example, the first through hole 11 and the second through hole 12 are of equal size. In other embodiments, the first through hole 11 and the second through hole 12 can be of different sizes. When the sizes are different, when the conveyor belt 1 moves, the center lines of the first through hole 11 and the second through hole 12 can overlap with each other. This is to enable the pressing head 9 to continue to move upward after passing through the first through hole 11 and the second through hole 12, so as to lift the pot blank 10.

[0026] The pressing head 9 is arranged on the workbench 2 in a liftable manner, and the pressing head 9 can pass through the second through hole 12 of the workbench 2 and move upward. The pressing head 9 has the freedom of rotation and can rotate with the rotation of the pot blank 10 after supporting the pot blank 10;

[0027] The turntable 4 is rotatably arranged just above the pressure head 9;

[0028] Among them, the pot blank 10 is placed on the conveyor belt 1 and moves with the conveyor belt 1. When the pot blank 10 moves to the position where the first through hole 11 and the second through hole 12 coincide with each other, the pressure head 9 can lift the pot blank 10 and make the upper end of the pot blank 10 contact with the turntable 4, so that the pressure head 9 and the turntable 4 can achieve the clamping effect of the pot blank 10.

[0029] A fixed frame 13 is provided below the workbench 2, and a cylinder 14 is installed on the fixed frame 13. The end of the telescopic rod of the cylinder 14 is connected to the pressure head 9 through a bearing. The cylinder 14 drives the pressure head 9 to move up and down. The pressure head 9 can be used to lift the pot blank 10 and rotate with the pot blank 10.

[0030] A vertical plate 3 is fixed on the upper side of the workbench 2, and a fixed plate 5 is installed on the top of the vertical plate 3. The fixed plate 5 is located directly above the second through hole 12 of the workbench 2. The turntable 4 is rotatably installed below the fixed plate 5 through a bearing. When the pressure head 9 pushes the pot blank 10 to the upper limit position, the pot blank 10 can be abutted against the turntable 4.

[0031] A motor 6 is installed on the top of the fixed plate 5. The output shaft of the motor 6 passes through the fixed plate 5 and is connected to the turntable 4. It is configured to drive the turntable 4 to rotate. Since the pressure head 9 and the turntable 4 clamp the pot blank 10, the pot blank 10 can be rotated when the turntable 4 rotates, thereby facilitating the edge grinding or edge curling of the pot blank 10.

[0032] The lower surface of the turntable 4 has a concave cavity 17 with a shape similar to the bottom of the pot blank 10, and an anti-slip pad 7 is fixed at the root position of the concave cavity 17. The setting of the concave cavity 17 is to match the bottom surface shape of the pot blank 10, so that the turntable 4 and the pot blank 10 are more fitted, and the force is uniform and stable when clamping the pot blank 10, thereby improving the stability of clamping. The anti-slip pad 7 is made of silicone or rubber material, and its purpose is to increase the friction between the pot blank 10 and the turntable 4, so as to avoid the problem of relative rotation between the turntable 4 and the pot blank 10 during rotation.

[0033] A plurality of exhaust holes 8 are provided on the side wall of the turntable 4, which can connect the internal space of the concave cavity 17 with the external space of the turntable 4, and are used to provide ventilation when the pot blank 10 moves upward into the concave cavity 17 of the turntable 4, and when the pot blank 10 moves downward, so as to avoid the problem that the local pressure inside the concave cavity 17 is too large, so that the pot blank 10 cannot move to the root position of the concave cavity 17, or is adsorbed and cannot fall when moving downward.

[0034] A sensor 16 for monitoring the position of the pot blank 10 is installed on one side of the upper surface of the workbench 2. In this embodiment, the sensor 16 is a proximity switch, which is arranged on the side of the second through hole 12 close to the workbench 2 to detect whether the pot blank 10 has moved to the specified position. It is connected to the PLC controller, and the PLC controller is connected to the cylinder 14 and the motor 6. After the pot blank 10 reaches the specified position, the clamping and rotation operations of the pot blank 10 can be started.

[0035] When this feeding and clamping mechanism for cookware production is working, the operator can place the pot blank 10 upside down on the conveyor belt 1, and position the pot blank 10 through the limiting protrusion 15 on the conveyor belt 1. The conveyor belt 1 drives the pot blank 10 to move toward the workbench 2. When the pot blank 10 moves to the position of the second through hole 12 of the workbench 2, the sensor 16 detects the position signal of the pot blank 10 and transmits the signal to the PLC controller. At this time, the cylinder 14 is started, driving the pressure head 9 to move upward, thereby driving the pot blank 10 to leave the conveyor belt 1 and move upward. When the pot blank 10 moves to the upper limit position, the turntable 4 contacts the pot blank 10, and the pressure head 9 and the turntable 4 jointly clamp the pot blank 10. Then the motor 6 is started, and the turntable 4 rotates to drive the pot blank 10 to rotate. During the rotation of the pot blank 10, the edge grinding or curling operation of the pot blank 10 can be performed. After the work is completed, the pressure head 9 moves down, and the pot blank 10 falls back on the conveyor belt 1 and is moved to the designated position by the conveyor belt 1.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
