Description

Technical Field

[0001] The utility model relates to the field of paper towel production and processing, in particular to a paper towel pile rotating material discharge mechanism. Background Art

[0002] During the production and processing of paper towels, it is necessary to process the paper towels into a specific size, and then take out a certain amount of the processed paper towels to form a paper towel stack of a specific size. After that, the paper towel stack is quantitatively packaged to form the well-known tissue paper on the market to facilitate subsequent transportation, sales and use.

[0003] However, the existing production and processing of paper towels has the following problems. On the one hand, after being processed into a specific size, the paper towels are often continuously fed out with their sides facing upward. In this way, during the feeding process, each paper towel is in contact with the surface with a large surface area, which can improve its tightness during feeding and effectively reduce the probability of the paper towel flying off due to external forces such as wind when it is fed with the surface with a large surface area facing upward. However, under this feeding method, the paper towels are fed into the packaging device with their sides facing upward, which makes it difficult to effectively package them.

[0004] On the other hand, the process of quantitatively taking out paper towels to form paper towel stacks mostly relies on manual work, which has high labor costs, low automation, low efficiency and weak market competitiveness. Utility Model Content

[0005] The utility model aims to provide a paper towel stack rotating material discharging mechanism, which can solve one or more of the above problems.

[0026] The paper feed rack 1 is fixedly mounted on the frame 6 by bolts. The paper feed rack 1 is provided with an inclined slide 12, which can allow continuous and overlapping paper towels to pass through the inclined slide 12. The inclined slide 12 is inclined, so the paper towels thereon can slide along the inclined slide 12 to a certain extent.

[0027] Limiting plates 11 are provided on both sides of the inclined slide 12 , and the limiting plates 11 can limit the paper towels in the inclined slide 12 to reduce the position deviation of the paper towels when they move in the inclined slide 12 .

[0028] The paper discharging rack 2 is fixedly mounted on the frame 6 by bolts, and the paper discharging rack 2 is located below the end of the inclined slide 12, so that the paper towels on the inclined slide 12 can be moved to the paper discharging rack 2 from the end of the inclined slide 12 through the driving energy of other structures.

[0031] The rotation guide mechanism 4 includes a second stopper 41, a second rotating shaft 42, a servo motor 43, a lifting mechanism 44 and a second bracket 45. The lifting mechanism 44 includes a slide rail 441, a slider 442 and a lifting cylinder 443. The second bracket 45 is fixedly mounted on the frame 6 by bolts, the slide rail 441 is fixedly connected to the second bracket 45 by bolts, the slider 442 is slidably arranged on the slide rail 441, the slider 442 is fixedly connected to the body of the servo motor 43 by bolts, and the output shaft of the servo motor 43 is connected to the second rotating shaft 42 through a gear box, so that the servo motor 43 can drive the second rotating shaft 42 to rotate.

[0032] In addition, the second stopper 41 is provided with a supporting section 411 and a paper blocking section 412, and the supporting section 411 and the paper blocking section 412 are vertically arranged.

[0033] The cylinder body of the lifting cylinder 443 is installed on the frame 6 through a pin shaft, and the piston rod of the lifting cylinder 443 is connected to the slider 442 through a connecting rod. The lifting cylinder 443 can drive the slider 442 to move up and down along the slide rail 441.

[0034] The upper paper stopper mechanism 3 and the rotating guide mechanism 4 can be moved to be located above and below the end point of the inclined slide 12 .

[0035] The paper separation mechanism 5 includes a spacer block 51, a second slider 52, a second slide rail and a second lifting cylinder 53. The second slide rail can preferably be the same slide rail as the first slide rail 33, that is, the second slide rail is also installed on the frame 6, and the second slider 52 is slidably arranged on the second slide rail. The second slider 52 can also be connected to a cylinder so that the second slider 52 can move along the second slide rail driven by the cylinder, and the cylinder body of the second lifting cylinder 53 is connected to the second slider 52 by bolts, and the spacer block 51 and the piston rod of the second lifting cylinder 53 are fixedly connected by bolts.

[0036] The paper separation mechanism 5 is arranged above the inclined slide 12, and when necessary, the separation block 51 can extend into the stacked paper towels of the inclined slide 12 and separate the paper towel stacks.

[0037] When the tissue stack rotating discharge mechanism is in use, the external conveying device enables the stacked tissues to be continuously conveyed into the inclined slide 12 in a direction perpendicular to the inclined slide 12 , and the tissues can slide along the inclined slide 12 .

[0038] According to the size of the paper towel stack that needs to be formed, the cylinder can drive the second slider 52 to slide, so that the partition block 51 is moved to the upper part of the inclined slide 12 at the required position, and the second lifting cylinder 53 drives the partition block 51 to move downward, and the partition block 51 extends into the stacked paper towels on the inclined slide 12 and separates the paper towel stack of the required size, and the paper towel stack can continue to slide along the inclined slide 12.

[0039] The cylinder can drive the first slide block 32 to slide, so that the first slide block 32 slides to make the first stop block 31 press against the upper part of the paper towel stack at the end of the inclined slide 12. At the same time, the first lifting cylinder 35 can drive the stop block 34 to move downward to press against the top of the paper towel stack to make the paper towel stack more flush.

Specifically, the upper paper stopper mechanism 3 works, and the cylinder drives the first slider 32 to slide, so that the first slider 32 slides to separate the first stopper 31 from the stack of paper towels. At the same time, the first lifting cylinder 35 also drives the stopper 31 to rise, and the stopper 31 is no longer in contact with the stack of paper towels. At this time, the stack of paper towels regains the tendency to slide forward, and the rotation guide mechanism 4 also works accordingly. The servo motor 43 can drive the second rotating shaft 42 to rotate, and the second stopper 41 rotates to move away from the inclined When the slide 12 reaches the end point, the stack of paper towels abutting against the second stopper 41 can rotate with the rotation of the second stopper 41, that is, the rotating guide mechanism 4 can drive the paper towels to rotate, and the lifting cylinder 443 drives the slider 442 to move slowly downward, that is, the second stopper 41 also moves slowly downward, that is, the stack of paper towels on the inclined slide 12 also moves downward with it under the action of gravity, and finally the stack of paper towels can complete the rotation with the action of the rotating guide mechanism 4 and be placed on the paper output rack 2, and the paper towels on the stack of paper towels change from the side facing upward to the large surface facing upward.

[0042] The stack of tissues on the paper discharging rack 2 can be subsequently packaged and processed by means of an external conveying mechanism.

[0043] The second lifting cylinder 53 can lift the spacer 51 to allow the new paper towel to continue to slide toward the end of the inclined slide 12, and move the spacer 51 down again in time to obtain a new stack of paper towels. By repeating the above process, a stack of paper towels with a large surface facing upward can be continuously obtained.

[0044] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
