[0040] The embodiments of the present application will be described below. Figures 1 to 5 The embodiments of the present application will be described below.

[0041] The present embodiment relates to an adjustable paperboard folding rod, comprising: a machine table 1, a front support rod 2, a rear support rod 3, a front guide rod 4, a rear guide rod 5, a driver 61, a driving plate 62; the front support rod 2 is arranged on the machine table 1; the rear support rod 3 is arranged on the machine table 1; the front end of the front guide rod 4 is connected with the front support rod 2 through a ball hinge structure, and the front guide rod 4 is a telescopic rod; the rear guide rod 5 is located above the front guide rod 4, and the rear end of the rear guide rod 5 is connected with the rear support rod 3 through a ball hinge structure, and the rear guide rod 5 is a telescopic rod; the driver 61 is arranged on the machine table 1; the driving plate 62 is driven to move by the driver 61, and the driving plate 62 is provided with a front adjusting rod and a rear adjusting rod, the front end of the front adjusting rod is connected with the rear end of the front guide rod 4 through a ball hinge structure, and the front end of the rear adjusting rod is connected with the rear end of the rear guide rod 5 through a ball hinge structure.

[0042] The paperboard folding rod is provided with a driver 61, which drives the driving plate 62 to move when it is actuated, and the front and rear ends of the front guide rod 4 and the rear guide rod 5 are supported through a ball hinge structure. The front guide rod 4 and the rear guide rod 5 have three degrees of rotational freedom, and the restriction on the front guide rod 4 and the rear guide rod 5 when the driving plate 62 drives them is small, so that the orientation of the front guide rod 4 and the rear guide rod 5 can be flexibly adjusted to adapt to paperboards of different sizes.

[0043] The paperboard has different sizes according to different orders. After the paperboard is scored, the paperboard is bent by the guide rods. When the paperboard is bent, the paperboard folding rod is adjusted to support the middle part of the paperboard to be folded up, so as to prevent the middle part of the paperboard from being folded down due to gravity after being folded up, and to affect the flatness of the paperboard. The adjustable paperboard folding rod in the embodiment moves the driving plate 62 upward when the large paperboard is bent, so as to increase the support height of the front guide rod 4 and the rear guide rod 5. When the small paperboard is bent, the driving plate 62 is moved downward, so as to avoid the small paperboard from falling off the front guide rod 4 and the rear guide rod 5 and causing the bending to be guided.

[0044] In the embodiment, the number of paperboard folding rods is two groups, and the two groups of paperboard folding rods are symmetrically arranged left and right. The two groups of paperboard folding rods are in the shape of an "eight" character. The paperboard is sent from the side with a large distance between the two groups of paperboard folding rods, and then is guided by the front guide rod 4 and the rear guide rod 5, folded up and sent out from the side with a small distance between the two groups of paperboard folding rods.

[0045] Further, the driving plate 62 is driven to move obliquely. The driving rod moves obliquely, and the oblique direction is that the lower end inclines toward the center of the paperboard. The driving plate 62 is adjusted by the driver 61, so as to better adapt to the adjustment of the bending of different paperboards. When the driving rod moves obliquely, the height of the driving plate 62 is adjusted, and the transverse position is also adjusted, so as to realize the adjustment of the speed of guiding the paperboard to be folded up in a simple driving structure form. In addition, the obliquely moving driving plate 62 also well adapts to the bending of paperboards of different specifications. For large order size paperboards, the size of the paperboard is large, and the thickness is usually large. At this time, the paperboard is bent at a relatively moderate speed. After the driving plate 62 moves obliquely upward, on the one hand, the support for the large order size paperboard is ensured, and on the other hand, the bending speed of the paperboard is reduced, which well adapts to the large order size paperboard. When the small order size paperboard is switched, the driving plate 62 moves obliquely downward, so as to prevent the small size paperboard from being separated from the front guide rod 4 and the rear guide rod 5, and to speed up the bending speed of the small order size paperboard, so as to provide sufficient time for the shaping of the paperboard.

[0046] The driver 61 is a driving motor. The paperboard folding rod further comprises a guide block 63, a driving wheel and a driving strip 64. The guide block 63 is fixed on the machine table 1. The guide block 63 is provided with a guide groove. The driving strip 64 slides along the guide groove. The lower end of the driving strip 64 is fixedly connected with the driving plate 62. The driving motor is drivingly connected with the driving wheel. The driving wheel abuts against the driving strip 64. The structure that the driving motor, the driving wheel and the driving strip 64 drive the driving plate 62 to move linearly along the guide groove to change the position of the driving plate 62 has the advantage of high adjustment precision.

[0047] The driving wheel is a gear wheel, and the driving strip 64 is a rack. The driving wheel and the driving strip 64 adopt a gear rack structure, which is beneficial to improving the precision of the driving motor.

[0048] The paperboard folding rod further comprises a front support fixed on the machine table 1, and the front support rod 2 is connected to the front support rod 2 through an adjusting structure. The adjusting structure between the front support and the front support rod 2 enables the position of the front support rod 2 to be adjusted, thereby meeting the debugging needs or meeting the needs of different paperboard debugging.

[0049] The adjusting structure comprises a waist-shaped slot, a lock column screw and a lock column screw hole. The waist-shaped slot is formed on the front support in the transverse direction, the lock column screw hole is formed at the bottom end of the front support rod 2, the front support rod 2 is located above the waist-shaped slot, and the lock column screw is screwed through the waist-shaped slot and the lock column screw hole. The adjusting structure is adjusted manually. Specifically, the lock column screw is screwed through the waist-shaped slot of the front support and is screwed with the lock column screw hole, and the front support rod 2 is locked on the front support. When the position of the front support rod 2 needs to be adjusted, the lock column screw needs to be loosened first, and then the position of the front support rod 2 is adjusted along the waist-shaped slot, and the lock column screw is locked again, so that the position of the front support rod 2 is adjusted, and the position of the front end of the front guide rod 4 is changed. After the size of the paperboard is determined, even if different order sizes of paperboard need to be replaced, the position of the front end of the front guide rod 4 usually does not need to be adjusted. The front guide rod 4 and the rear guide rod 5 only play a role in guiding the bending of the paperboard. The paperboard has been pre-pressed before entering the front guide rod 4. When the paperboard is guided by the front guide rod 4 and the rear guide rod 5, it only plays a role in folding the paperboard, and does not participate in determining the bending position of the paperboard. The position of the front support rod 2 can be manually adjusted to meet the needs of use. The position of the front support rod 2 is usually only adjusted during installation and debugging.

[0050] The paperboard folding rod further comprises a sliding seat 71, a sliding strip 72 and a locking structure. The sliding seat 71 is fixed on the machine table 1, the sliding strip 72 slides along the sliding seat 71, the rear support rod 3 is fixed on the sliding strip 72, and the locking structure releasably locks the sliding strip 72 on the sliding seat 71. The position of the rear support rod 3 can be adjusted by sliding the sliding strip 72 along the sliding seat 71, and is locked by the locking structure after adjustment. The adjustment of the position of the rear support rod 3 is the same as the adjustment of the position of the front support rod 2. Usually, it also only needs to be adjusted during installation and debugging.

[0051] The locking structure comprises a locking screw sleeve and a locking screw 73. The locking screw sleeve is fixed on the machine table 1, the locking screw 73 is screwed with the locking screw sleeve, and the tail of the locking screw 73 presses the sliding strip 72 on the sliding seat 71. Thus, by loosening and re-locking the locking screw 73, the position of the rear end of the rear guide rod 5 can be adjusted.

[0052] The preferred embodiments of the present application have been disclosed with specific reference to a preferred embodiment, to all embodiments within the scope of the following claims as equivalents of the embodiments disclosed in detail, and to individual features of the application. The application is thus deemed to cover all logical, mechanical, and electrical equivalents to those specifically shown and described herein, including all alternatives to features of the application.
