Description

Technical Field

[0001] The present invention relates to the technical field of glass pot lid production equipment, and in particular to a pot lid edge wrapping device. Background Art

[0002] Cookware is an essential kitchen utensil in family life. There are many types of cookware, and most cookware comes with a pot lid. Covering the cookware with a pot lid can prevent food ingredients from falling out of the cookware during cooking, and also prevent foreign objects from falling into the cookware to contaminate the food ingredients. Existing pot lids usually include a lid body, a steel ring, and a silicone ring. The steel ring is wrapped around the outer edge of the lid body. The lower end of the silicone ring is provided with a flanging that extends outward. The flanging is used to achieve good contact with the upper edge of the cookware to achieve sealing. During installation, first place the silicone ring on the steel ring, then place the lid body on the card slot at the lower end of the silicone ring, and then use an edge wrapping device to press the upper edge of the steel ring against the upper edge of the lid body, so that the lid body is pressed against the silicone ring to complete the edge wrapping operation of the pot lid. However, when the existing edge wrapping machine performs the edge wrapping operation on the pot lid, the downward curling amplitude of the upper edge of the steel ring under pressure is very uneven, resulting in a relatively low quality of the pot lid edge wrapping and reducing the product quality. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. For this purpose, the present invention provides a pot lid edge wrapping device with high edge wrapping quality.

[0004] According to an embodiment of the present invention, the pot lid edge wrapping device includes a rotating part, a pressing part, and a profiling part. The rotating part is provided with a turntable and a rotation driving mechanism. The turntable is provided with a mounting position, and a mold for placing the pot lid is mounted at the mounting position. The mold is provided with a supporting part for separating the steel ring of the pot lid from the elastic sealing ring. The rotation driving mechanism is used to drive the turntable to rotate. The pressing part is provided with a pressing block and a pressing driving mechanism. The pressing block is used to press the steel ring of the pot lid. The pressing driving mechanism is used to drive the pressing block to move vertically. The profiling part is provided with a profiling table, a sliding table, and a profiling driving mechanism. The pressing driving mechanism is mounted on the profiling table. The profiling table is rotatably mounted on the sliding table. The profiling driving mechanism is used to drive the sliding table to drive the profiling table to press against the outer edge of the turntable.

[0005] The edge wrapping device for the pot lid according to the embodiment of the present invention has at least the following beneficial effects: When wrapping the edge, the pot lid is placed on the mold, and the supporting part of the mold separates the steel ring of the pot lid from the turned edge of the elastic sealing ring. Driven by the rotation driving mechanism, the turntable drives the pot lid to rotate. The profiling driving mechanism drives the sliding table to drive the profiling table to press against the outer edge of the turntable. The downward pressing driving mechanism drives the downward pressing block to move downward to press against the upper edge of the steel ring of the pot lid, so as to press and roll the upper edge of the steel ring onto the upper edge of the lid body. As the turntable rotates, the downward pressing block follows the profiling table to sequentially roll and press the upper edges of the outer periphery of the steel ring onto the upper edge of the lid body, thereby completing the edge wrapping operation of the pot lid. Since the supporting part of the mold separates the steel ring from the turned edge of the elastic sealing ring, the supporting part can provide good support for the lower end of the steel ring. Thus, when the upper edge of the steel ring is stressed, the steel ring is supported by the supporting part and will not move downward, thereby reducing the situation of the steel ring vibrating up and down under stress, making the rolling of the upper edge of the steel ring more balanced under the downward pressure, greatly improving the quality of edge wrapping, and being beneficial to improving the quality of the product.

[0035] The applicant has continuously conducted research in the pot lid edge wrapping industry and found that the reason for the poor edge wrapping quality of the existing pot lid edge wrapping device is that the silicone ring has good elasticity. When the edge wrapping device presses down the steel ring, the steel ring is stressed and moves downward. At this time, the lower end of the steel ring will abut against the flanging at the lower end of the silicone ring. Due to the good elasticity of the silicone ring, the steel ring will vibrate up and down on the flanging of the silicone ring when stressed, resulting in a very uneven amplitude of the upper edge of the steel ring being pressed and turned downward, thus reducing the edge wrapping quality and affecting the product quality.

[0036] Therefore, referring to Figures 1 to 7 , the applicant has proposed the pot lid edge wrapping device of the embodiment of the present invention, which includes a rotating part 100, a pressing part 200, and a profiling part 300. Of course, it may also include a workbench 500. The rotating part 100 is provided with a turntable 110 and a rotation driving mechanism. The turntable 110 is installed at the upper end of the workbench 500, and the rotation driving mechanism is installed at the lower end of the workbench 500. The turntable 110 is provided with an installation position 111, and a mold 120 for placing the pot lid 600 is installed at the installation position 111. The pot lid 600 includes a lid body 610, a steel ring 620, and an elastic sealing ring 630. The elastic sealing ring 630 can be a silicone ring or other elastic rings. The mold 120 is provided with a support part 121 for separating the steel ring 620 of the pot lid 600 from the elastic sealing ring 630. The support part 121 can be in a ring shape. The outer contour of the installation position 111 can be provided with a plurality of notches 112 to facilitate the removal of the mold 120. The rotation driving mechanism is used to drive the turntable 110 to rotate. The rotation driving mechanism can be a motor and its transmission mechanism, and the transmission mechanism can be a belt transmission mechanism, so that the rotation of the turntable 110 is more stable, which is beneficial to improving the edge wrapping quality and reducing the phenomenon of edge wrapping creases caused by the transmission clearance of transmission mechanisms such as chain transmission. The pressing part 200 is provided with a pressing block 220 and a pressing driving mechanism 210. The pressing block 220 is used to press down the steel ring 620 of the pot lid 600, and the pressing driving mechanism 210 is used to drive the pressing block 220 to move vertically. The pressing driving mechanism 210 can be a cylinder driving mechanism. The profiling part 300 is provided with a profiling table 330, a sliding table 320, and a profiling driving mechanism 310. The pressing driving mechanism 210 is installed on the profiling table 330. The profiling table 330 is rotatably installed on the sliding table 320. The profiling driving mechanism 310 is used to drive the sliding table 320 to drive the profiling table 330 to abut against the outer edge of the turntable 110. The profiling driving mechanism 310 can be a cylinder driving mechanism.

[0037] When hemming, place the pot lid 600 on the mold 120 of the turntable 110. The support portion 121 of the mold 120 separates the lower end of the steel ring 620 from the flange 631 of the elastic sealing ring 630. Driven by the rotary drive mechanism, the turntable 110 drives the pot lid 600 to rotate. The profiling drive mechanism 310 drives the sliding table 320 to drive the profiling table 330 to press against the outer edge of the turntable 110. The downward pressing drive mechanism 210 drives the downward pressing block 220 to move downward to press against the upper edge of the steel ring 620 of the pot lid 600, so as to press and roll the upper edge of the steel ring 620 onto the upper edge of the cover body 610. As the turntable 110 rotates continuously, the downward pressing block 220 follows the profiling table 330 to press and roll the upper edges of the outer circumference of the steel ring 620 onto the upper edge of the cover body 610 in sequence, thus completing the hemming operation of the pot lid 600. Since the support portion 121 of the mold 120 separates the lower end of the steel ring 620 from the flange 631 of the elastic sealing ring 630, the support portion 121 can provide good support for the lower end of the steel ring 620. Therefore, when the upper edge of the steel ring 620 is stressed, the steel ring 620 is supported by the support portion 121 and will not move downward, thereby reducing the situation of the steel ring 620 vibrating up and down under stress, making the upper edge of the steel ring 620 roll more evenly when receiving the downward pressure, greatly improving the quality of hemming and being beneficial to improving the product quality.

[0038] In some embodiments of the present invention, the downward pressing block 220 is provided with a first roller 221 and an adjusting rod 222. The first roller 221 is rotatably installed at the end of the adjusting rod 222, and the adjusting rod 222 is telescopically adjusted and installed at the output end of the downward pressing drive mechanism 210. During operation, the downward pressing block 220 presses and rolls along the steel ring 620 through the first roller 221, so as to press the upper edge of the steel ring 620 onto the cover body 610. The first roller 221 can improve the smoothness of the downward pressing movement of the downward pressing block 220 along the steel ring 620, which is beneficial to improving the quality of hemming. In addition, according to different product sizes, by adjusting the installation position of the adjusting rod 222 relative to the output end of the downward pressing drive mechanism 210, the position of the first roller 221 can be adjusted to meet different product requirements.

[0039] In some embodiments of the present invention, a fixing block 211 is provided at the output end of the downward pressing drive mechanism 210. The fixing block 211 is provided with a connection hole, and the adjusting rod 222 passes through the connection hole and is locked by a locking nut. When it is necessary to adjust the position of the adjusting rod 222, the adjusting rod 222 can be loosened by rotating the locking nut, then the adjusting rod 222 is moved to the required position, and then the locking nut is tightened to lock the adjusting rod 222 on the fixing block 211, and the adjustment operation is relatively convenient.

[0040] In some embodiments of the present invention, the pressing-down part 200 is further provided with a speed stabilizer 230. The speed stabilizer 230 is located at the upper end of the pressing-down driving mechanism 210. A contact plate 240 cooperating with the speed stabilizer 230 is provided at the upper end of the pressing-down driving mechanism 210. The output end of the pressing-down driving mechanism 210 is connected with a lifting frame 250, and the speed stabilizer 230 is installed on the lifting frame 250. When the output end of the pressing-down driving mechanism 210 drives the pressing-down block 220 and the lifting frame 250 to move downward, when the pressing-down block 220 is about to contact the upper edge of the steel ring 620, the extending rod 231 of the speed stabilizer 230 first touches the contact plate 240, causing the speed stabilizer 230 to act. The extending rod abuts against the contact plate 240, so that the output end of the pressing-down driving mechanism 210 moves downward at a lower and uniform speed. Thus, when the pressing-down block 220 presses the upper edge of the steel ring 620, the force on the steel ring 620 is more balanced, which is beneficial to further improving the quality of edge wrapping.

[0041] Specifically, the profiling table 330 includes an upper platform 333, a lower platform 334 and a driving cylinder 335. The lower platform 334 is rotatably installed on the sliding table 320. The upper platform 333 is slidably installed on the lower platform 334. The driving cylinder 335 is used to drive the upper platform 333 to move on the lower platform 334 to approach or move away from the turntable 110. The pressing-down driving mechanism 210 is installed on the upper platform 333. One end of the upper platform 333 facing the turntable 110 is provided with a second roller 331. Two third rollers 332 are provided on the lower platform 334. The two third rollers 332 are respectively arranged on both sides of the second roller 331. When the second roller 331 is stressed, it can move back and forth relative to the third rollers 332. The second roller 331 and the third rollers 332 enable the profiling table 330 to move smoothly along the outer circumference of the turntable 110, so that the profiling table 330 can be kept in close contact with the outer edge of the turntable 110. Specifically, the turntable 110 is generally square, and its corner positions are arc positions. Since three points can determine an arc, by providing two fixed third rollers 332 and one movable second roller 331, when the corner position of the turntable 110 rotates to the profiling table 330, the second roller 331 moves back and forth relative to the two third rollers 332, so that the arrangement of the second roller 331 and the two third rollers 332 matches the arc of the corner position of the turntable 110. Thus, all three rollers can be kept in close contact with the outer edge of the turntable 110, which is beneficial for the pressing-down driving mechanism 210 installed on the upper platform 333 to keep the pressing-down block 220 pressing tightly on the steel ring 620 of the pot lid 600 on the turntable 110.

[0042] In some embodiments of the present invention, the profiling part 300 is provided with a slide rail 321, and the sliding table 320 is slidably installed on the slide rail 321. By providing the slide rail 321, the sliding of the sliding table 320 is made more stable and smooth, which is beneficial to improving the quality of edge wrapping.

[0043] In some embodiments of the present invention, there are two slide rails 321, and the two slide rails 321 are arranged at intervals, so as to further improve the smoothness of the sliding of the sliding table 320.

[0044] In some embodiments of the present invention, the pot lid edge wrapping device further includes a pressing part 400. The pressing part 400 is provided with a pressing head 420 and a pressing driving mechanism 410. The pressing head 420 is used to press the pot lid against the turntable 110, and the pressing driving mechanism 410 is used to drive the pressing head 420 to move vertically. By providing the pressing part 400, when edge wrapping, the upper end of the pot lid is pressed by the pressing head 420 to prevent the pot lid from easily shaking up and down, which is beneficial to improving the quality of edge wrapping.

[0045] In some embodiments of the present invention, the pressing head 420 has an elastic buffer layer, and the elastic buffer layer is arranged at the lower end of the pressing head 420. The elastic buffer layer can buffer the impact force between the pressing head 420 and the pot lid, and prevent the pressing head 420 from easily damaging the pot lid.

[0046] In the above embodiments, the elastic buffer layer can be a silicone layer or a cotton layer. Both the silicone layer and the cotton layer have good buffering effects and can be specifically selected according to actual needs.

[0047] Since the upper part of the lid body 610 of the pot lid 600 is usually an arc surface, when the pot lid 600 rotates with the turntable 110, the height of the arc surface of the lid body 610 may change. For this reason, the pressing part 400 is also provided with a spherical plain bearing. The pressing head 420 is connected to the output end of the pressing driving mechanism 410 through the spherical plain bearing, so that the pressing head 420 can adapt to the change of the arc surface height of the lid body 610 and keep pressing on the lid body 610, which is beneficial to improving the quality of edge wrapping.

[0048] The embodiments of the present invention have been described in detail above with reference to the drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the gist of the present invention.
