[0032] In one embodiment of the present invention, Figures 1-2 As shown, a wine box special-shaped single-opening upper cover hemming machine is provided, which is used for hemming a wine box special-shaped single-opening upper cover 100 having a long plate portion 101 and a short plate portion 102. The long plate portion 101 and the short plate portion 102 are connected together. The long plate portion 101 has two long sides and two short sides. The short plate portion 102 also has two long sides and two short sides. Of course, the lengths of the two long sides and the two short sides of the short plate portion 102 can be the same. At the same time, the two long sides of the long plate portion 101 are respectively located on the same side as the two long sides of the short plate portion 102, and the short side of the long plate portion 101 is located on the side facing away from the short plate portion 102.

[0033] Furthermore, the wine box special-shaped single-opening upper cover 100 has a facial tissue on the outer surface and a gray board on the inner surface. The facial tissue on the outer surface has a larger area than the gray paper on the inner surface, that is, the excess part of the outer peripheral edge of the facial tissue on the outer surface needs to wrap the gray board on the inner surface. The wine box special-shaped single-opening upper cover edge wrapping machine of this embodiment realizes the automated operation of this work.

[0034] Specifically, the wine box special-shaped single-opening upper cover hemming machine includes a base 10, an upper cover mold 20 and five molding and pressure-keeping devices. The upper cover mold 20 is arranged on the table top of the base 10, and the upper cover mold 20 is detachably connected to the base 10, so that it can be replaced. The shape of the upper cover mold 20 is adapted to the shape of the wine box special-shaped single-opening upper cover 100 that needs to be hemmed, and the upper cover mold 20 is used to carry the wine box special-shaped single-opening upper cover 100. The five molding and pressure-keeping devices are respectively arranged on the surrounding sides of the upper cover mold 20, and the five molding and pressure-keeping devices are respectively used to hem the two long sides and one short side of the long plate part 101 of the wine box special-shaped single-opening upper cover 100 carried in the upper cover mold 20 and the two long sides of the short plate part 102.

[0035] In the wine box special-shaped single-opening upper cover hemming machine provided in the embodiment of the present invention, the wine box special-shaped single-opening upper cover 100 that needs to be hemmed is placed on the upper cover mold 20 set on the base 10, and then the various molding and pressure-keeping devices are started. The molding and pressure-keeping devices hem the two long sides and one short side of the long plate part 101 and the two long sides of the short plate part 102 of the wine box special-shaped single-opening upper cover 100 carried in the upper cover mold 20, thereby realizing automated hemming of the wine box special-shaped single-opening upper cover 100, reducing the work intensity of personnel, improving work efficiency, enhancing product quality, and saving costs for the enterprise.

[0036] Compared with traditional manual hemming, the present invention not only greatly reduces the workload of operators, but also increases the work efficiency by three times. The upper cover of the equipment hemming is smoother, and the phenomena of empty edges and rebound are eliminated, achieving the goals of high output, high efficiency and high quality.

[0037] In another embodiment of the present invention, Figures 1-2As shown, the molding pressure-maintaining device includes a downward pressure transmission mechanism 30, a torsion spring rebound mechanism 32 and a molding pressure-maintaining plate 33. The molding pressure-maintaining plate 33 is vertically arranged on the side of the upper cover mold 20. The torsion spring rebound mechanism 32 is connected between the upper cover mold 20 and the molding pressure-maintaining plate 33 and applies a rebound force on the molding pressure-maintaining plate 33 to keep it in a vertical state. The downward pressure transmission mechanism 30 is installed on the base 10 and is used to drive the molding pressure-maintaining plate 33 to rotate so as to overcome the rebound force and press against the edge of the wine box special-shaped single-opening upper cover 100 carried in the upper cover mold 20. Specifically, the downward pressing transmission mechanism 30 outputs power, and then transmits the force to the forming pressure-maintaining plate 33, forcing the forming pressure-maintaining plate 33 to overcome the rebound force applied to the forming pressure-maintaining plate 33 by the torsion spring rebound mechanism 32, so that the forming pressure-maintaining plate 33 rotates to press against the edge of the wine box special-shaped single-opening upper cover 100 carried in the upper cover mold 20, and realizes automatic hemming. After completing a single hemming, the downward pressing transmission mechanism 30 retreats, and the forming pressure-maintaining plate 33 returns to its original state under the rebound force applied by the torsion spring rebound mechanism 32, maintains a vertical state, and waits for the next work, and the cycle is repeated, and the production efficiency is greatly improved.

[0038] In another embodiment of the present invention, Figure 2 As shown, the torsion spring rebound mechanism 32 includes a hinge 321 and a torsion spring 322, the hinge 321 has a first page 3211, a second page 3212 and a rotating shaft 3213 connecting the first page 3211 and the second page 3212 together, the first page 3211 of the hinge 321 is connected and fixed to the upper cover mold 20, the second page 3212 of the hinge 321 is connected and fixed to the bottom of the forming pressure maintaining plate 33, the torsion spring 322 is sleeved in the rotating shaft 3213 of the hinge 321, and one free end of the torsion spring 322 is abutted against the first page 3211, and the other free end of the torsion spring 322 is abutted against the second page 3212. Specifically, under the action of the torsion spring 322, the first sheet 3211 and the second sheet 3212 are always in an unfolded state, so that the forming pressure-maintaining plate 33 connected to the second sheet 3212 is always in a vertical state, so that when the external force acting on the second sheet 3212 causes the second sheet 3212 to rotate relative to the first sheet 3211, once the external force is removed, the second sheet 3212 can be restored to its original state. In this way, when the forming pressure-maintaining plate 33 completes a single hemming operation under the action of the downward pressure transmission mechanism 30, the downward pressure transmission mechanism 30 removes the external force, and the forming pressure-maintaining plate 33 can be reset under the action of the torsion spring rebound mechanism 32 and wait for the next hemming operation.

[0039] In another embodiment of the present invention, Figure 1As shown, the downward pressure transmission mechanism 30 includes a driving source 311, a mounting seat 312, an L-shaped rod 313 and a rotating member 314. The mounting seat 312 is installed on the table top of the base 10. A fixed shaft 3121 is provided on the mounting seat 312. The L-shaped rod 313 includes a horizontal rod segment 3131 and a vertical rod segment 3132. Preferably, the horizontal rod segment 3131 and the vertical rod segment 3132 are integrally formed and arranged at ninety degrees or approximately ninety degrees. The horizontal rod segment 3131 is passed through by the fixed shaft 3121 and is rotatably connected to the fixed shaft 3121. The rotating member 314 is rotatably installed on the outer side of the forming pressure maintaining plate 33 and abuts against the vertical rod segment 3132. The driving source 311 is installed inside the base 10 and its output end is connected to the horizontal rod segment 3131 to drive the L-shaped rod 313 to rotate around the fixed shaft 3121 and make the vertical rod segment 3132 press against the rotating member 314. Specifically, the driving source 311 outputs power to act on the L-shaped rod 313, and the L-shaped rod 313 rotates around the fixed shaft 3121 installed on the mounting seat 312. The vertical rod section 3132 of the L-shaped rod 313 is pressed down during the rotation process, thereby pressing against the rotating member 314 provided on the outer side of the forming pressure-maintaining plate 33. Then, as the L-shaped rod 313 continues to be pressed down, the rotating member 314 rotates along its length direction on the vertical rod section 3132, forcing the forming pressure-maintaining plate 33 to yield to the rebound force and thus press down until the wine box special-shaped single-opening upper cover 100 is hemmed. The downward pressing transmission mechanism 30 is ingeniously designed and highly practical.

[0040] In another embodiment of the present invention, Figures 1-2 As shown, the rotating member 314 is a rotating bearing. The rotation of the bearing reduces friction and improves the use effect.

[0041] In another embodiment of the present invention, Figures 1-2 As shown, a bearing seat 315 is provided on the outer side of the molded pressure-maintaining plate 33, and the rotating bearing is rotatably mounted on the bearing seat 315. The bearing seat 315 can be locked on the outer side of the molded pressure-maintaining plate 33 by a fastener, and then the rotating bearing is mounted on the bearing seat 315 by a connecting shaft.

[0042] In another embodiment of the present invention, Figures 1-2 As shown, the driving source 311 is a driving cylinder, which is installed vertically, and the piston rod of the driving cylinder is connected to the horizontal rod section 3131. Specifically, the piston rod of the driving cylinder is extended to drive the horizontal rod to flip up, and then the vertical rod section 3132 of the L-shaped rod 313 is pressed down. During the pressing process, the rotating bearing rotates on the vertical rod section 3132, and the forming pressure-maintaining plate 33 is pressed down to realize the hemming of the wine box special-shaped single-opening upper cover 100 on the upper cover mold 20.

[0043] The base 10 is also provided with a barometer 40 to display the air pressure when the driving cylinder is working.

Specifically, the connection holes provided on the centering adjustment rod 316 can be connected to the horizontal rod segment 3131 of the L-shaped rod 313. Since the connection holes are at different positions, each connection hole is connected to the horizontal rod segment 3131, so that the L-shaped rod 313 is at a different angle, thereby changing the downward pressing angle of the L-shaped rod 313 to adapt to the edging of different types of special-shaped single-opening upper covers 100 of wine boxes, and the use is more flexible.

[0045] In another embodiment of the present invention, Figures 1-2 As shown, two vertically protruding support columns 3122 are provided on the mounting seat 312, and the two support columns are arranged at intervals, and the two ends of the fixed shaft 3121 are respectively connected and fixed to the two support columns. Specifically, the arrangement of the two support columns allows the fixed shaft 3121 to be hung high, so that the installation position of the L-shaped rod 313 is improved, and the rotation of the L-shaped rod 313 is more flexible and free from interference.

[0046] In another embodiment of the present invention, Figures 1-2 As shown, the two opposite outer sides of the base 10 are provided with handles 11. The two handles 11 can be easily lifted to facilitate the whole wine box special-shaped single-opening upper cover hemming machine, thereby facilitating the operation of moving and carrying it.
