Description

Technical Field

[0001] This utility model relates to the field of material bucket equipment technology, and in particular to a material bucket lid closing device. Background Technology

[0002] A material hopper is a device for holding materials. It is frequently used in the food, pharmaceutical, and chemical industries. For example, material hoppers are installed on equipment such as granulators, sizing machines, and mixers. In the current technology, material hoppers are usually equipped with lids for sealing. The lid is opened when adding or discharging materials, and closed when processing the materials in the hopper to prevent the materials from overflowing or scattering. However, this operation of opening or closing the lid is done manually, which does not meet the standards of automated production operations. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings and deficiencies of the existing technology and to provide a bucket lid closing device. This utility model uses independent lid closing and lid opening devices to perform separate lid closing or opening operations, replacing traditional manual operation and meeting the standards of modern automated production operations.

[0004] The technical solution adopted by this utility model is as follows: A material bucket closing device includes a material bucket and a bucket lid. A support part is provided on the edge of one end of the opening of the material bucket. A pin is provided on the support part. The bucket lid is rotatably connected to the material bucket through the pin. The bucket lid has a closed position that is closed with the material bucket and an open position that abuts against the support part. It also includes a closing device and an opening device provided on the outside of the material bucket. The closing device drives the bucket lid to rotate from the open position to the closed position. The opening device drives the bucket lid to rotate from the closed position to the open position. When the bucket lid is in the open position, the opening device is separated from the bucket lid. When the bucket lid is in the closed position, the closing device is separated from the bucket lid.

[0005] It also includes a column, on which the lid-closing device is mounted. The lid-closing device includes a first telescopic cylinder, a connecting rod, and a rotating rod. The first telescopic cylinder extends and retracts to drive the first telescopic rod. One end of the rotating rod is a contact end, and the other end is a connecting end. The middle part of the rotating rod is rotatably mounted on the column via a rotating shaft. One end of the connecting rod is connected to the connecting end, and the other end is connected to the first telescopic rod. When the first telescopic cylinder drives the first telescopic rod to extend, the connecting rod drives the rotating rod to rotate until it separates from the lid. When the first telescopic cylinder drives the first telescopic rod to retract, the connecting rod drives the rotating rod to rotate until it contacts the lid and causes the lid to rotate.

[0006] The end of the contact terminal is provided with a buffer block.

[0007] When the lid is in the open position, it is parallel to the horizontal plane. The lid also has a closed position. When the lid is in the closed position, there is a first included angle of acute angle between the lid and the bucket. The rotating rod drives the lid to rotate from the open position to the closed position.

[0008] The lid opening device includes a second telescopic cylinder and an extension lid. The second telescopic cylinder drives a second telescopic rod to extend and retract. The extension lid is detachably installed on the lid. When the second telescopic cylinder drives the second telescopic rod to extend, the second telescopic rod contacts the extension lid and drives the lid to rotate. When the second telescopic cylinder drives the second telescopic rod to retract, the second telescopic rod separates from the extension lid.

[0009] The end of the second telescopic rod is provided with a buffer ball, and the extension cover plate is provided with an inclined surface for contacting the buffer ball. The thickness of the end of the extension cover plate away from the pin is greater than the thickness of the end closer to the pin.

[0010] The lid also has a ready-to-open position. When the lid is in the ready-to-open position, there is a second included angle between the lid and the bucket, which is also an acute angle.

[0011] The beneficial effects of this utility model are as follows: By setting up a dedicated lid-closing device and a lid-opening device, and having them drive the lid-closing and lid-opening operations respectively, the traditional manual operation mode is completely replaced. This significantly improves production efficiency and reduces the labor intensity of operators. Both the lid-closing device and the lid-opening device can be electrically connected to the equipment's control system, such as a PLC, to achieve automatic control, fully meeting the standards and requirements of modern automated production operations. The lid-closing device and the lid-opening device use independent drive components and do not need to be installed on the material bucket or lid. They only contact the lid when the corresponding operation is performed. This makes it applicable to various types of material buckets. The device is also easy to replace or maintain individually. The lid can be stably maintained in the open position, providing space for safe and convenient feeding or discharging operations. Attached Figure Description

[0017] like Figures 1 to 5 As shown in the figure, a material bucket closing device is provided in one embodiment of the present invention. The device includes a material bucket 1 and a bucket lid 2. A support part 3 is provided on the edge of the opening end of the material bucket 1. A pin 4 is provided on the support part 3. The bucket lid 2 is rotatably connected to the material bucket 1 through the pin 4. The bucket lid 2 has a closed position that is closed with the material bucket 1 and an open position that abuts against the support part 3. The device also includes a closing device and an opening device provided on the outside of the material bucket 1. The closing device drives the bucket lid 2 to rotate from the open position to the closed position. The opening device drives the bucket lid 2 to rotate from the closed position to the open position. When the bucket lid 2 is in the open position, the opening device is separated from the bucket lid 2. When the bucket lid 2 is in the closed position, the closing device is separated from the bucket lid 2.

[0018] The beneficial effects of this design are as follows: By setting up dedicated lid-closing and lid-opening devices, and having them drive the lid-closing and lid-opening operations separately, the traditional manual operation mode is completely replaced. This significantly improves production efficiency and reduces the labor intensity of operators. Both the lid-closing and lid-opening devices can be electrically connected to the equipment's control system, such as a PLC, to achieve automatic control, fully meeting the standards and requirements of modern automated production operations. The lid-closing and lid-opening devices use independent drive components and do not need to be installed on the material bucket or lid. They only contact the lid when the corresponding operation is performed, making them applicable to various types of material buckets. The device is also easy to replace or maintain individually. The lid can be stably maintained in the open position, providing space for safe and convenient feeding or discharging operations. The lid is rotatably connected to the material bucket via a pin, equivalent to a hinge connection.

[0019] Further configuration includes a column 5, on which the lid-closing device is mounted. The lid-closing device includes a first telescopic cylinder 6, a connecting rod 7, and a rotating rod 8. The first telescopic cylinder 6 extends and retracts to drive a first telescopic rod 9. One end of the rotating rod 8 is a contact end 10, and the other end is a connecting end 11. The middle part of the rotating rod 8 is rotatably mounted on the column 5 via a rotating shaft 12. One end of the connecting rod 7 is connected to the connecting end 11, and the other end is connected to the first telescopic rod 9. When the first telescopic cylinder 6 drives the first telescopic rod 9 to extend, the connecting rod 7 drives the rotating rod 8 to rotate until it separates from the lid 2. When the first telescopic cylinder 6 drives the first telescopic rod 9 to retract, the connecting rod 7 drives the rotating rod 8 to rotate until it contacts the lid 2 and causes the lid 2 to rotate.

[0020] The beneficial effects of this design are as follows: the lever mechanism consisting of the first telescopic cylinder, connecting rod, and rotating rod efficiently converts the linear motion of the cylinder into the rotational motion of the rotating rod, thereby driving the lid. This linkage mechanism has force amplification and self-locking characteristics, which can ensure that the lid closing action is powerful, in place, and reliably sealed.

[0021] As a further feature, a buffer block 13 is provided at the end of the contact end 10.

[0022] The beneficial effects of this design are as follows: when the rotating rod rotates to contact the lid, the buffer block can effectively absorb the impact energy generated by the collision, significantly reducing noise and vibration during the closing process and improving the working environment. The buffer block can be made of existing sponge shock-absorbing blocks.

[0023] Further configuration: when the lid 2 is in the open position, the lid 2 is parallel to the horizontal plane. The lid 2 also has a closed position. When the lid 2 is in the closed position, there is a first included angle 14 with an acute angle between the lid 2 and the material bucket 1. The rotating rod 8 drives the lid 2 to rotate from the open position to the closed position.

[0024] The beneficial effects of this design are as follows: the closing process is clearly divided into two stages: from opening to closing and from closing to closing. The rotation angle of the rotating rod is controlled by the cooperation of the connecting rod and the first telescopic rod. The rotating rod can only rotate back and forth and cannot rotate 360°. That is, the connecting end can only rotate to the right side of the column or be coaxial with the column. The rotating rod will only drive the lid to the closing position. The structure of the closing device can be simpler and the drive is more labor-saving. In this embodiment, the first included angle is 82°. The rotation from the closing position to the closed position can be achieved by the gravity of the lid itself. This achieves the decoupling and optimization of the drive function and is conducive to precise control for the characteristics of different stages.

[0025] In a further configuration, the lid-opening device includes a second telescopic cylinder 15 and an extension lid 16. The second telescopic cylinder 15 drives a second telescopic rod 17 to extend and retract. The extension lid 16 is detachably mounted on the lid 2. When the second telescopic cylinder 15 drives the second telescopic rod 17 to extend, the second telescopic rod 17 contacts the extension lid 16 and drives the lid 2 to rotate. When the second telescopic cylinder 15 drives the second telescopic rod 17 to retract, the second telescopic rod 17 separates from the extension lid 16.

[0026] The advantages of this design are as follows: the extended cover plate adopts a detachable installation structure, such as the bolt and nut installation in the prior art, which can be adapted to various types and sizes of bucket lids. The lid opening device is also located on the outside of the bucket. When the bucket lid is in the open position, the lid closing device will not interfere with the extended cover plate and the bucket lid. Moreover, the lid opening device also adopts a drive structure of telescopic cylinder and telescopic rod. The second telescopic rod contacts the extended cover plate to open the lid, which simplifies the transmission structure, makes the force flow path clear and direct, and reduces the manufacturing cost.

[0027] In a further configuration, the end of the second telescopic rod 17 is provided with a buffer ball 18, and the extension cover plate 16 is provided with an inclined surface 19 for contacting the buffer ball 18. The thickness of the end of the extension cover plate 16 away from the pin 4 on the inclined surface 19 is greater than the thickness of the end near the pin 4.

[0028] The beneficial effects of this design are as follows: the buffer ball can be an elastic shock-absorbing ball with existing technology. The buffer ball can effectively absorb the impact at the moment of contact, avoid rigid collision, significantly reduce the noise and vibration when the lid is opened and started, and protect related components. By sliding the buffer ball along the inclined surface, the lid is rotated to the open position, changing the direction of the transmission force. Otherwise, the straight up and down movement of the second telescopic rod cannot drive the lid to rotate more than 90°. The spherical structure reduces the friction between the buffer ball and the inclined surface, making it easier for the buffer ball to slide along the inclined surface until the lid is opened.

[0029] Furthermore, the bucket lid 2 also has a ready-to-open position. When the bucket lid 2 is in the ready-to-open position, there is a second included angle 20 between the bucket lid 2 and the material bucket 1, which is also an acute angle.

[0030] The beneficial effects of this setting are as follows: In this embodiment, the second included angle is 55°, which is smaller than the first included angle. The bucket lid can be opened to the open position to meet the feeding or discharging processes. Sometimes, only a shorter secondary feeding is required. The bucket lid can be rotated by a small angle to meet the requirements. It is not necessary to rotate it completely to the open position. After feeding is completed, the second telescopic rod can be retracted to close the bucket lid. There is no need for the lid closing device to drive it. The output power consumption of both the lid opening device and the lid closing device can be effectively reduced.

[0031] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
