Description

Technical Field

[0001] This utility model relates to the field of processing equipment technology, specifically to an automatic sealing ring installation device for box lids. Background Technology

[0002] Currently, most box structures, such as food storage containers, are usually composed of a box body and a lid. In order to ensure the sealing effect between the box body and the lid, a sealing ring needs to be installed between the lid and the box body.

[0003] In existing technologies, most of the installation of sealing rings and box covers is done manually, requiring assembly workers to manually hammer them in. This results in low assembly efficiency and is prone to improper assembly or damage to the sealing ring, affecting product quality and production efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an automatic sealing ring installation device for box lids. It overcomes the deficiencies of existing technologies, has a reasonable design, achieves automated and efficient pressing, ensures precise fitting of each sealing ring, improves production efficiency and sealing quality, and is suitable for mass production needs.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automatic sealing ring installation device for a box lid includes a base and a lifting seat. The upper surface of the base has a box lid placement groove. Multiple guide posts are vertically fixed at the corners of the upper surface of the base. Multiple guide bushings are fixedly embedded at the corners of the lifting seat. The lifting seat is axially slidably connected to the outer surface of the guide posts through the guide bushings.

[0007] A hollow rotating shaft is rotatably connected to the middle of the lifting seat via a bearing. A transmission wheel is fixedly installed on the upper end of the hollow rotating shaft. A first motor is fixedly installed above the lifting seat, and the output shaft of the first motor is connected to the transmission wheel. A rotating ring is fixedly connected to the lower end of the hollow rotating shaft. A first linear guide rail is radially arranged on the outer circumference of the rotating ring. A cylinder is slidably connected to the lower surface of the first linear guide rail via a slider. A pressure column is fixedly connected to the lower end of the telescopic rod of the cylinder. A cam roller is installed on the upper end of the cylinder. A cam groove is opened on the lower surface of the lifting seat, and the cam roller is movably connected in the cam groove.

[0008] A second motor is fixedly installed above the lifting seat. The output shaft of the second motor is connected to the rotating shaft via a coupling. The lower end of the rotating shaft passes through the hollow rotating shaft and is equipped with a tensioning and positioning device. The tensioning and positioning device corresponds vertically to the lid placement slot.

[0009] Preferably, the clamping and positioning device includes a cam disk and an outer sleeve. The cam disk is coaxially fixedly installed at the lower end of the rotating shaft. The surface of the cam disk has multiple oblong holes, which are centrally symmetrically arranged and expand outward from the center. Multiple second linear guides are radially arranged and centrally symmetrically arranged above the cam disk. The second linear guides are fixedly installed at the lower end of the outer sleeve. The upper end of the outer sleeve is fixedly installed on the lower surface of the lifting seat. A positioning claw is slidably connected to the lower part of the second linear guides via a slider. A rotating roller is installed on the lower surface of the positioning claw and is movably connected in the oblong holes.

[0010] Preferably, a limiting plate is fixedly installed on the lower outer side of the outer casing, and the limiting plate is in movable contact with the side of the positioning claw.

[0011] Preferably, the lower end of the first motor is fixedly mounted on the lifting seat by a support column, and a drive wheel is coaxially fixedly mounted on the outer surface of the output shaft of the first motor. The drive wheel is connected to the transmission wheel by a belt.

[0012] Preferably, an installation frame is fixedly installed above the lifting seat, the transmission wheel is disposed inside the installation frame, and the second motor is fixedly installed above the installation frame.

[0013] This invention provides an automatic sealing ring installation device for box lids, which has the following advantages: The rotation of the rotating shaft drives the positioning claws of the clamping and positioning device to open outwards, thereby opening the sealing ring directly above the box lid to form a predetermined shape. The extension rod of the controlled cylinder moves the pressure column downwards to abut against the upper surface of the sealing ring, pressing it into the sealing groove of the box lid. Then, the first motor is started, driving the transmission wheel and hollow rotating shaft to rotate via its output shaft. Through the guiding and limiting effect of the cam groove, the cylinder, during rotation, adapts to the shape of the cam groove by moving axially along the first linear guide rail, ensuring that the cylinder's movement trajectory corresponds to the shape of the cam groove. This effectively ensures that the movement trajectory of the pressure column perfectly matches the shape of the sealing groove of the box lid, achieving precise pressing of the sealing ring. The entire process achieves automated and efficient pressing, ensuring precise fit of each sealing ring, improving production efficiency and sealing quality, and is suitable for mass production needs.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0023] Example 1, as Figure 1-5 As shown, an automatic sealing ring installation device for box lids includes a base 1 and a lifting seat 2. The upper surface of the base 1 is provided with a box lid placement groove 3 for placing box lids. Four guide posts 4 are vertically fixedly installed at the corners of the upper surface of the base 1. Four guide bushings corresponding to the guide posts 4 are fixedly embedded at the corners of the lifting seat 2. The lifting seat 2 is slidably connected to the outer surface of the guide posts 4 along the axial direction through the guide bushings.

[0024] A hollow rotating shaft 5 is rotatably connected to the middle of the lifting seat 2 via a bearing. A transmission wheel 6 is coaxially fixedly mounted on the upper end of the hollow rotating shaft 5. A first motor 7 is fixedly mounted on the top of the lifting seat 2, and the output shaft of the first motor 7 is connected to the transmission wheel 6. A rotating ring 8 is fixedly connected to the lower end of the hollow rotating shaft 5. A first linear guide rail 9 is radially arranged on the outer circumference of the rotating ring 8. A cylinder 10 is slidably connected to the lower surface of the first linear guide rail 9 via a slider. A pressure column 11 is fixedly connected to the lower end of the telescopic rod of the cylinder 10. A cam roller 12 is movably mounted on the upper end of the cylinder 10. A cam groove 13 is opened on the lower surface of the lifting seat 2, and the cam roller 12 is movably connected in the cam groove 13. The shape of the cam groove 13 matches the shape of the sealing groove of the box cover.

[0025] A second motor 14 is fixedly installed above the lifting seat 2. The output shaft of the second motor 14 is connected to the rotating shaft 15 through the coupling 21. The lower end of the rotating shaft 15 passes through the hollow rotating shaft 5 and is equipped with a tensioning and positioning device 16. The tensioning and positioning device 16 corresponds vertically to the box cover placement groove 3.

[0026] Working principle:

[0027] In the initial state, the lifting seat 2 is raised to the initial height at the top, and the positioning claw of the positioning device 16 is in the retracted state.

[0028] In use, first place the lid into the lid placement slot 3 to position and fix the lid, and then place the sealing ring directly above the lid; then control the lifting seat 2 to descend to the predetermined position. In this embodiment, the lifting seat 2 can be connected to an external telescopic cylinder, which drives the lifting seat 2 to slide up and down along the axial direction of the guide column 4; then control the second motor 14 to operate, so that the rotation of the rotating shaft 15 drives the positioning claw of the clamping and positioning device 16 to open outward, thereby opening the sealing ring directly above the lid outward so that the sealing ring forms a predetermined shape.

[0029] Subsequently, the telescopic rod of the control cylinder 10 drives the pressure column 11 to move downwards to abut against the upper surface of the sealing ring and press the sealing ring into the sealing groove of the lid. Then, the first motor 7 is started, and the output shaft of the first motor 7 drives the transmission wheel 6 to rotate, which in turn drives the hollow rotating shaft 5 and the rotating ring 8 to rotate synchronously. The rotation of the rotating ring 8 drives the cylinder 10 on the first linear guide rail 9 to rotate. Since the cam roller 12 at the upper end of the cylinder 10 is slidably connected to the cam groove 13, the guiding and limiting effect of the cam groove 13 allows the cylinder 10 to move adaptively along the axial direction of the first linear guide rail 9 during rotation, so that the movement trajectory of the cylinder 10 corresponds to the shape of the cam groove 13. This effectively ensures that the movement trajectory of the pressure column 11 is completely matched with the shape of the sealing groove of the lid, thereby achieving precise pressing of the sealing ring and ensuring that the sealing ring can be accurately pressed into the sealing groove of the lid after the pressure column 11 rotates once. In this way, the sealing ring and the sealing groove of the box lid are tightly combined to form a reliable sealing structure, ensuring the airtightness of the items inside the box.

[0030] Subsequently, the second motor 14 is reversed to control the retraction of the positioning claw of the clamping and positioning device 16, and at the same time, the cylinder 10 is controlled to drive the pressure column 11 upward to retract to the initial position, and then the lifting seat 2 is controlled to rise back to the initial height. Then, the box cover with the sealing ring pressed on is taken out, and then the subsequent box covers and sealing rings are placed back into the box cover placement slot 3. The above steps are repeated to complete the sealing ring pressing work of multiple box covers in sequence.

[0031] The entire process achieves automated and efficient pressing, ensuring precise fit of each sealing ring, improving production efficiency and sealing quality, and is suitable for mass production needs.

[0032] Example 2, as Figure 4-5 As shown, as a further preferred embodiment of the first embodiment, the tensioning and positioning device 16 includes a cam disk 161 and an outer sleeve seat 162. The cam disk 161 is coaxially fixedly installed at the lower end of the rotating shaft 15. The surface of the cam disk 161 has four oblong holes 163, which are centrally symmetrically arranged and expand outward from the center. Four second linear guides 164 are radially arranged and centrally symmetrically arranged above the cam disk 161. The second linear guides 164 are fixedly installed at the lower end of the outer sleeve seat 162. The upper end of the outer sleeve seat 162 is fixedly installed on the lower surface of the lifting seat 2. The lower end of the rotating shaft 15 passes through the outer sleeve seat 162 and is connected to the cam disk 161. A positioning claw 165 is slidably connected to the lower part of the second linear guides 164 via a slider. A rotating roller 166 is installed on the lower surface of the positioning claw 165 and is movably connected in the oblong holes 163.

[0033] Therefore, during the process of the positioning claw of the clamping and positioning device 16 being opened outward by the rotation of the rotating shaft 15, the rotation of the rotating shaft 15 first drives the cam disk 161 to rotate. Since the positioning claw 165 is limited to the axial movement direction of the second linear guide rail 164, and since the rotating roller 166 at the lower end of the positioning claw 165 is movably connected in the oblong hole 163, when the cam disk 161 rotates, the positioning claw 165 will move outward along the axial direction of the second linear guide rail 164 under the guide trajectory of the oblong hole 163, thereby effectively opening the sealing ring. Similarly, when the positioning claw of the clamping and positioning device 16 is retracted by the reverse rotation of the rotating shaft 15, the rotation of the rotating shaft 15 drives the cam disk 161 to rotate in the opposite direction, thereby allowing the positioning claw 165 to retract along the axial direction of the second linear guide rail 164 under the reverse guidance of the oblong hole 163, thus achieving precise control of the positioning claw 165.

[0034] In Example 3, as a further preferred embodiment of Example 2, four limiting plates 167 are evenly fixedly installed on the lower outer side of the outer sleeve 162. The four limiting plates 167 respectively make movable contact with the sides of the four positioning claws 165. The limiting plates 167 effectively limit the movement range of the positioning claws 165, ensuring their stability during opening and retraction, further improving the accuracy and reliability of the sealing ring press-fit. This design not only avoids errors in the traditional press-fit process but also significantly reduces manual intervention, making the entire press-fit process smoother and more efficient.

[0035] In Example 4, as a further preferred embodiment of Example 1, the lower end of the first motor 7 is fixedly mounted on the lifting seat 2 via a support column 17. A drive wheel 18 is coaxially fixedly mounted on the outer surface of the output shaft of the first motor 7. The drive wheel 18 is connected to the transmission wheel 6 via a belt 19. The belt 19 ensures stable transmission between the drive wheel 18 and the transmission wheel 6. At the same time, the elastic adjustment function of the belt 19 ensures smooth transmission under different loads and reduces wear.

[0036] In Example 5, as a further preferred embodiment of Example 4, a mounting frame 20 is fixedly installed above the lifting seat 2, the transmission wheel 6 is disposed within the mounting frame 20, and the second motor 14 is fixedly installed above the mounting frame 20. The mounting frame 20 ensures the stable fixation of the second motor 14 and also effectively protects the transmission wheel 6.

[0037] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
