Description

[Technical field]

[0001] The utility model relates to the technical field of black card paper pressing equipment, in particular to a black card paper pressing device. [Background technology]

[0002] Black card paper is a kind of card paper, and its color is black, hence the name black card paper. Due to its special texture and feel, it is widely used in packaging fields such as packaging boxes. Black card paper is generally made of multiple sheets of paper pressed together, thereby improving the hardness and density of black card paper. In the process of pressing black card paper, a pressing device is generally used. By using the pressing device to press the paper, the processing efficiency of black card paper is increased. The existing pressing device mainly consists of a transmission roll 1, a transmission roll 2, a hot pressing roller 1 with a heating wire, and a hot pressing roller 2 with a heating wire. The black card paper is respectively transmitted to between the hot pressing roller 1 and the hot pressing roller 2 by the transmission roll 1 and the transmission roll 2, and the two black card papers are hot-pressed by the hot pressing roller 1 and the hot pressing roller 2, thereby realizing the production of black card paper;

[0003] Although the above method can realize the processing of black card paper, during the transmission process of transmission roll one and transmission roll two, the black card paper is very easy to appear wrinkles during transmission. Once the black card paper is wrinkled, when the subsequent hot pressing roller one and hot pressing roller two heat press the black card paper, one of the wrinkled black card paper or two black card papers will be heat pressed together, which will affect the quality of the black card paper pressing and also affect its aesthetics. [Contents of the utility model]

[0006] The bracket is located between the pressing piece and the paper jam conveying mechanism and is driven to slide in the vertical direction and is connected with a relatively arranged smoothing mechanism;

[0007] The smoothing mechanism comprises a support, a belt, a connecting block and a smoothing roller;

[0008] The support is driven to slide vertically and connected to the bracket, and the belt is driven to rotate relatively and connected to the support;

[0009] There are a plurality of connecting blocks, all of which are fixedly connected to the belt. The smoothing roller is transversely arranged on the connecting block, and the smoothing roller can be arranged opposite to the black card paper.

[0010] Preferably, a bidirectional lead screw is rotatably connected to the bracket, the bidirectional lead screw is threadedly connected to the support, a motor 1 is fixedly connected to the bracket, and the output shaft of the motor 1 is fixedly connected to the bidirectional lead screw.

[0011] Preferably, a sliding rod is fixedly connected to the bracket, a limiting block three is fixedly connected to the sliding rod, and one end of the support away from the bidirectional lead screw is slidably connected to the sliding rod.

[0012] Preferably, one end of the bracket close to the support is rotatably connected to a positioning roller, and the positioning roller can position the jammed paper.

[0013] Preferably, a sliding block is slidably connected to the connecting block, the smoothing roller is rotatably connected to the sliding block, a spring is fixedly connected to the connecting block, and one end of the spring is fixedly connected to the sliding block.

[0014] Preferably, the connection block is fixedly connected to a limiting block 1, the sliding block is fixedly connected to a limiting block 2, and the limiting block 1 can be attached to the limiting block 2.

[0015] Preferably, a connecting plate is obliquely and fixedly connected to the support, and a guide roller is rotatably connected to the connecting plate.

[0016] The beneficial effects of the utility model are as follows: compared with the prior art, a smoothing mechanism is arranged on the bracket, and the support in the smoothing mechanism is used to move relative to each other, so that the support assists in driving the smoothing roller to stick to the paperboard, and then the relative rotation of the belt is used to make the belt drive the connecting block to drive the smoothing roller to move relative to each other, thereby smoothing the paperboard. The relative movement of the smoothing roller can smooth the paperboard, which can reduce the wrinkles of the paperboard when it enters the hot pressing roller for hot pressing, thereby increasing the quality of the black paperboard pressing, and at the same time indirectly increase the aesthetics of the paperboard by reducing the wrinkles when the paperboard is pressed.
