It includes a base with a motor welded inside. The output end of the motor is fixedly connected to a rotating wheel via a coupling. A winding mechanism is located on the right side of the base, and a platform is welded to the center of the upper surface of the base. This invention, through the coordinated operation of the motor, rotating wheel, pneumatic telescopic column, fixing mechanism, cutter, platform, support, winding frame, and receiving mechanism, allows for adjustments to the specific dimensions required for trimming according to different production needs. The winding mechanism promptly winds up the trimmed toilet paper, facilitating winding and preventing contamination that could lead to substandard production quality. It also receives and pushes out and uniformly processes any debris.

[0003] The adjustable trimming mechanism for a toilet paper production line mentioned above requires changing to different sizes of corresponding cutters when trimming toilet paper with different trimming requirements, which increases the cost of the equipment and reduces its economic benefits.

Detailed Implementation

[0021] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0022] Please see Figure 1-3 This utility model provides a technical solution: a paper roll trimming mechanism for a toilet paper production line, including a base plate 1 and an adjustment mechanism 3. Two sets of cutters 4 are arranged above the base plate 1, and a mounting frame 2 is fixedly installed on the top of the base plate 1. A threaded rod 7 and a suction hopper 13 are arranged above the base plate 1. The adjustment mechanism 3 is arranged on the mounting frame 2 and is used to adjust the distance between the two sets of cutters 4.

[0023] The adjustment mechanism 3 includes a motor 301, a bidirectional threaded rod 302, an adjustment disc 303, and a limit rod 304. The motor 301 is fixedly installed on the other side of the mounting frame 2. The bidirectional threaded rod 302 is rotatably installed inside the mounting frame 2. The output group of the motor 301 extends into the interior of the mounting frame 2 and is fixedly installed with the bidirectional threaded rod 302. Two sets of adjustment discs 303 are threadedly connected to the outer wall of the bidirectional threaded rod 302. Two sets of through holes are opened on the two sets of adjustment discs 303. The limit rod 304 is slidably installed in the two sets of through holes. When there are requirements for the trimming size of toilet paper, the adjustment mechanism 3 can adjust the distance between the two sets of cutters 4. Compared with replacing the corresponding cutters of different sizes, it can reduce the purchase cost of the equipment and thus improve its economic benefits.

[0024] The outer walls of both sets of adjusting discs 303 are fixedly connected to a set of cutters 4, and a set of identical through holes are opened on both sides of 2.

[0025] The mounting frame 2 has a threaded rod 7 rotatably mounted inside. Both the threaded rod 7 and the double-threaded rod 302 have a set of pulleys 5 fixedly mounted on their outer walls. A belt 6 is sleeved between the two sets of pulleys 5 and is connected by the belt 6 for transmission. The outer wall of the threaded rod 7 is threadedly connected to a take-up drum 8. During the process of trimming toilet paper, the waste toilet paper strips generated during trimming can be taken up, thereby reducing the workload of subsequent operators and improving the efficiency of toilet paper trimming.

[0026] A vacuum pump 10 and a storage tank 11 are fixedly installed on the top of the mounting frame 2. The suction end of the vacuum pump 10 extends into the interior of the storage tank 11 and is fixedly installed thereto. A connecting pipe 12 is fixedly installed on the top inner side of the mounting frame 2. One end of the connecting pipe 12 extends into the interior of the storage tank 11, and the other end of the connecting pipe 12 is fixedly installed with the suction hopper 13. A shut-off valve is provided on the outer wall of the connecting pipe 12. A door is hinged to the front of the storage tank 11, and a handle is fixedly installed on the front of the door.

[0027] The mounting bracket 2 has two sets of rotating rollers 9 rotatably mounted inside, and the two sets of rotating rollers 9 are located directly below the two sets of cutters 4.

[0028] Working principle: The starter motor 301 is controlled, and the output shaft of the motor 301 rotates, driving the bidirectional threaded rod 302 to rotate. Through the action of the limit rod 304, the rotation of the bidirectional threaded rod 302 can adjust the distance between the two sets of adjusting discs 303, thereby adjusting the distance between the two sets of cutters 4. After adjustment, the limit rod 304 is pulled out, and one end of the toilet paper passes through the surface of the two sets of rotating rollers 9 and is wound and fixed on the take-up drum 8. The rotation of the two sets of cutters 4 can trim the toilet paper, and one end of the waste paper strip is wound and fixed to the threaded rod 7. Through the action of the pulley 5 and the belt 6, the rotation of the threaded rod 7 can wind the waste paper strip onto the threaded rod 7 and wind the finished product onto the take-up drum 8. By starting the vacuum pump 10, the vacuum pump 10 draws air from the inside of the storage box 11 to create a negative pressure inside. The shut-off valve on the connecting pipe 12 is closed, so that the dust generated by trimming can be sucked into the storage box 11 through the suction hopper 13.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
