The second box body has a first opening, and the limit swing arm and the cylinder are arranged on the side wall of the second box body from top to bottom in sequence along the vertical direction and are located at the lower side of the first opening. The limit swing arm and the cylinder abut against each other, and one end of the film rolling rod penetrates into the first box body and is fixed to the rotating bearing seat, and the other end of the film rolling rod penetrates into the second box body from the first opening and is locked by limiting the position of the limit swing arm. If the cylinder moves downward, the limit swing arm can be rotated to disengage from the limiting position of the film rolling rod, and then one end of the film rolling rod is horizontally rotated under the drive of the rotating bearing seat.

[0007] Furthermore, the film rolling rod is horizontally arranged along the left-right direction, and the film rolling rod includes a left section of the film rolling rod, a middle section of the film rolling rod and a right section of the film rolling rod, which are respectively located at the left end, middle part and right end of the film rolling rod, and the diameters of the left section of the film rolling rod and the right section of the film rolling rod are both smaller than the diameter of the middle section of the film rolling rod, and the lengths of the left section of the film rolling rod and the right section of the film rolling rod are both smaller than the length of the middle section of the film rolling rod.

[0024] The utility model is further described in detail below with reference to the embodiments given in the accompanying drawings.

[0025] like Figures 1 to 6As shown, a single swing arm structure suitable for a laminating machine described in this embodiment includes a film rolling rod 1 extending in a horizontal direction, a rotating mechanism 2 and a locking mechanism 3, the rotating mechanism 2 includes a first box body 21 and a rotating bearing seat 22 arranged on the side wall of the first box body 21, the locking mechanism 3 includes a second box body 31, a limit swing arm 32 and a cylinder 33, a first opening 311 is provided on the side wall of the second box body 31, the limit swing arm 32 and the cylinder 33 are arranged in sequence from top to bottom in the vertical direction on the side wall of the second box body 31 and are located at the first opening 311 On the lower side, the limiting swing arm 32 and the cylinder 33 abut against each other, one end of the film rolling rod 1 passes through the first box body 21 and is fixed to the rotating bearing seat 22, and the other end of the film rolling rod 1 passes through the second box body 31 from the first opening 311 and is locked by the limiting swing arm 32. If the cylinder 33 moves downward, the limiting swing arm 32 can be rotated to disengage from the limitation of the film rolling rod 1, and then one end of the film rolling rod 1 can be horizontally rotated under the drive of the rotating bearing seat 22. The film rolling rod 1 rotates unilaterally in the horizontal direction, which is convenient for taking and placing the film roll material on the film rolling rod 1.

[0026] In this embodiment, the film rolling rod 1 is horizontally arranged along the left and right directions, and the film rolling rod 1 includes a left section 11, a middle section 12 and a right section 13 of the film rolling rod, which are respectively located at the left end, middle and right ends of the film rolling rod 1, and the diameters of the left section 11 and the right section 13 of the film rolling rod are smaller than the diameter of the middle section 12 of the film rolling rod, and the lengths of the left section 11 and the right section 13 of the film rolling rod are smaller than the length of the middle section 12 of the film rolling rod.

[0027] In this embodiment, the limiting swing arm 32 and the cylinder 33 are arranged on the inner wall of the second box body 31. The front end of the limiting swing arm 32 is hinged on the inner wall of the second box body 31 and is located at the lower side of the first opening 311. The rear end of the limiting swing arm 32 is rotatable and extends upward in an arc shape. The rear end of the limiting swing arm 32 is higher than the front end of the limiting swing arm 32. When there is no need to take material, the rear end of the limiting swing arm 32 will limit the right section 13 of the film rolling rod.

[0028] In this embodiment, the width of the front opening end of the first opening 311 is smaller than the width of the rear opening end of the first opening 311 , and the right section 13 of the film rolling rod can be released from the rear opening end of the first opening 311 when the film rolling rod 1 rotates.

[0029] In this embodiment, two piston rods 331 are symmetrically arranged in the cylinder 33 along the up and down directions. The parts of the two piston rods 331 exposed outside the cylinder 33 are connected to a fixing plate 332. The upper end surface of the fixing plate 332 abuts against the lower end surface of the limiting swing arm 32. When the cylinder 33 is not working, the fixing plate 332 abuts against the limiting swing arm 32 to limit the right section 13 of the film rolling rod. When the cylinder 33 is working, the two piston rods 331 move downward so that the fixing plate 332 moves downward with it, and the limiting swing arm 32 rotates clockwise and no longer limits the right section 13 of the film rolling rod.

[0030] In this embodiment, it also includes a first limiting bearing sleeve 41, a first limiting groove 131 is provided on the right section 13 of the film rolling rod, and two first bearings 42 are sleeved on the right section 13 of the film rolling rod, which are respectively limited by the two side walls of the first limiting groove 131. The first limiting bearing sleeve 41 is outermost on the two first bearings 42, and the first limiting bearing sleeve 41 partially extends into the first opening 311 and is limited by the limiting swing arm 32. When the right section 13 of the film rolling rod rotates in the first opening 311, the two first bearings 42 contact with the first limiting bearing sleeve 41 to support the rotation of the right section 13 of the film rolling rod, so that the friction between the right section 13 of the film rolling rod and the first opening 311 is reduced when the film rolling rod rotates horizontally, thereby reducing energy consumption.

[0031] In this embodiment, a second opening 211 is provided on the side wall of the first box body 21, and the rotating bearing seat 22 is embedded in the second opening 211 and fixed thereto. The left section 11 of the film rolling rod passes through the rotating bearing seat 22 into the first box body 21. The rotating bearing seat 22 has the characteristic of 360-degree rotation. When the rotating bearing seat 22 rotates, the film rolling rod 1 will also rotate with it.

[0032] In this embodiment, it also includes a second limiting bearing sleeve 43, a spacer sleeve 5 is sleeved on the left section 11 of the film rolling rod, and three second bearings 44 limited by the spacer sleeve 5 are sleeved on the left side of the spacer sleeve 5 on the left section 11 of the film rolling rod. The second limiting bearing sleeve 43 is outermost on the three second bearings 44. When the film rolling rod 1 is not limited by the limiting swing arm 32, the contact between the three second bearings 44 and the second limiting bearing sleeve 43 allows the left section 11 of the film rolling rod to rotate in the horizontal direction, and the friction resistance is reduced when the left section 11 of the film rolling rod contacts the first box body 21.

[0033] When the laminating machine is working, the film roll material on the film rolling rod 1 is rotated and provided to the laminating machine. When the film roll material rotates, the second limit bearing sleeve 43 is in rotational contact with the first box body 21, and the first limit bearing sleeve 41 is in rotational contact with the first opening 311. Because the second limit bearing sleeve 43 is outermost on the three second bearings 44, and the first limit bearing sleeve 41 is outermost on the two first bearings 42, the friction resistance of the film rolling rod 1 is greatly reduced when it rotates.

[0034] In this embodiment, an upper fixed seat 212 and a lower fixed seat 213 are respectively provided at the upper and lower ends of the first box body 21. After the right section 13 of the film rolling rod is no longer limited by the limiting swing arm 32, the upper fixed seat 212 and the lower fixed seat 213 contact the second limiting bearing sleeve 43, so that the rotating bearing seat 22 rotates in the horizontal direction.

[0035] Usually, a film roll is wound on the middle section 12 of the film rolling rod for use in a laminating machine. When the film roll material needs to be replaced, the cylinder 33 is operated to move downward, and the limit swing arm 32 rotates clockwise under the action of gravity. The right section 13 of the film rolling rod is no longer limited. Since the rotating bearing seat 22 has the characteristic of 360-degree free rotation, the second limit bearing sleeve 43 contacts the upper fixed seat 212 and the lower fixed seat 213, so that the rotating bearing seat 22 rotates in the horizontal direction, driving the film rolling rod 1 to disengage from the rear opening end of the first opening 311 with the rotating bearing seat 22 as the center. The staff does not need to take out the film rolling rod 1 to take and put the film roll material, which is convenient and efficient.

[0036] In this embodiment, the rotating mechanism 2, the film rolling rod 1 and the locking mechanism 3 are located on the same vertical plane.

[0037] The above is only a preferred embodiment of the present utility model, and it cannot be used to limit the scope of the present utility model. That is, all simple equivalent changes and modifications made according to the scope of the patent application of the present utility model and the content of the utility model description are still within the scope of the present utility model patent.
