[0002] For the pull-out paper product production line, the base paper is conveyed out through a fully automatic soft-pull folding machine. Factory users require that the rear part of the topmost paper product be folded inward to form a half-folded paper tail to facilitate consumers to pull out the first paper towel. Therefore, during the processing, the paper product needs to be flipped over, and the flipping angle is 180°.

DETAILED DESCRIPTION

[0022] Various exemplary embodiments, features and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0023] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0024] In addition, in order to better illustrate the present application, numerous specific details are provided in the specific embodiments below. It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, and elements well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0025] For the pull-out paper product production line, the base paper is conveyed out by the fully automatic soft pull-out folding machine. The factory user requires that the rear part of the topmost paper product be bent inward to form a half-folded paper tail to facilitate consumers to pull out the first paper towel. Therefore, the utility model aims to propose a flipping device to achieve the above operation. The specific implementation method is as follows: Please refer to Figure 1-Figure 6 In an embodiment of the utility model, a 180-degree automatic flipping device for clamping and feeding paper products comprises a symmetrically arranged mounting seat 5 and a driving shaft 11 that penetrates the mounting seat 5 and is rotatably connected to the mounting seat 5. Preferably, the driving shaft 11 is rotatably connected to the mounting seat 5 through a bearing, and the bearing adopts a circular seat bearing with a tightening sleeve, which can increase the service life of the bearing, reduce the damage and maintenance cost of the bearing, and at the same time improve the stability and safety of the equipment, providing protection for industrial production. The driving shaft 11 is driven to rotate by a driving source; two turntables 1 are fixed on the driving shaft 11, and the turntable 1 is colinear with the axis of the driving shaft 11; two mounting frames 2 are symmetrically arranged along the plane where the axis of the driving shaft 11 is located at a position between the two rotating disks 1, and the mounting frame 2 is connected to a clamping driving member installed on the rotating disk 1; a plurality of clamping plates 10 are fixed on both sides of the mounting frame 2, and the clamping plates 10 on the two mounting frames 2 form two clamping positions for clamping paper products 14 relative to each other.

[0026] In this embodiment, the two clamping positions are symmetrically arranged to form two loading positions or unloading positions, and the driving shaft 11 is driven by the set driving source to rotate 180°, so that the two clamping positions can be flipped, thereby realizing the clamping and flipping operations of the paper product 14. The automatic clamping of the paper product 14 is realized by the set clamping drive component, with a high degree of automation and convenient clamping, which effectively improves the production efficiency.

[0027] It should be noted that the mounting base 5 is used to support the drive shaft 11, the drive source and the integral components mounted on the drive shaft 11. The device can be installed on a workbench, a wall panel or other work positions, and the specific installation position can be selected according to actual needs.

[0028] Specifically, the driving source includes a motor 20, which is preferably a servo motor. The output end of the motor 20 is connected to one end of the driving shaft 11 through a reducer. The motor 20 is installed in a driving shell 3 fixed to the mounting base 5. Preferably, a cooling fan 4 is provided on the driving shell 3 for dissipating heat from the motor 20.

[0029] The motor 20 is set to drive the drive shaft 11 to rotate through the reducer, thereby driving the overall rotation installed on the drive shaft 11 to achieve the flipping of the clamping position. In this embodiment, the flipping angle of the clamping position is preferably 180°. The heat dissipation treatment of the motor 20 can be achieved through the heat dissipation fan 4, thereby improving the stability of the movement of the motor 20.

[0030] Preferably, a connecting seat 19 is installed on the mounting seat 5 away from the motor 20, and a motor-controlled detection head 17 is provided on the connecting seat 19. The motor-controlled detection head 17 is adapted to two trigger members 18 fixed on the drive shaft 11. When the drive shaft 11 rotates, the trigger members 18 are driven to rotate synchronously. When one of the trigger members 18 rotates to a position opposite to the motor-controlled detection head 17, the motor 20 stops working and remains in a locked state, thereby realizing automatic control of the operation of the motor 20 and ensuring that the two clamping positions maintain a constant flip of 180° when flipping.

[0031] Furthermore, the two opposite clamps 10 on the two mounting frames 2 form a group of clamping units, and the clamping unit includes a first clamp and a second clamp; a baffle 15 is fixed on the first clamp, and a guide hole 16 for the baffle 15 to pass through is formed on the second clamp, or a baffle 15 is fixed on the second clamp, and a guide hole 16 for the baffle 15 to pass through is formed on the first clamp; the fixing positions of the baffles 15 on two adjacent groups of clamping units are different.

[0032] A space for placing the paper product 14 is formed between the baffle 15 and the two clamping plates 10. When clamping the paper product 14, the limiting effect of the baffle 15 can realize the correction of the paper product 14 and prevent the paper product 14 from moving excessively and affecting subsequent operations.

[0033] By sliding the baffle 15 through the guide hole 16 , the problem of interference caused by the baffle 15 when the clamping action is performed between two adjacent clamping plates 10 can be eliminated, and on the other hand, it can ensure that no offset occurs between the two clamping plates 10 .

[0034] Furthermore, the clamping drive member includes two cylinders 6 that are staggered, and the cylinders 6 are installed on the turntable 1. The movable ends of the two cylinders 6 are respectively installed with movable supporting members, and the movable supporting members are detachably connected to the mounting frame 2. The two cylinders 6 are used to drive the two movable supporting members to move toward or oppositely. Exemplarily, in one embodiment, the movable supporting member includes a connecting frame 9 that is detachably connected to the mounting frame 2, and a slider 8 is fixed on the connecting frame 9, and the slider 8 is slidably connected to a slide rail 7 installed on the turntable 1.

[0035] The connecting frame 9 is driven to move by the arranged cylinder 6 when it telescopes, and the sliding block 8 and the sliding rail 7 are slidably cooperated to ensure the directional sliding of the connecting frame 9. When the two cylinders 6 telescope synchronously, the two mounting frames 2 can move synchronously toward or in opposite directions to drive the clamping plate 10 to perform a clamping action or a releasing action.

[0036] Integrating the clamping drive member on the turntable 1 can ensure that the clamping state is maintained when the paper product 14 is conveyed, and the clamping action is performed after the rotation is required, eliminating the influence of the rotation of the drive shaft 11 on the clamping action performed by the clamping drive member.

[0037] Preferably, a buffer 12 is also fixed on the connecting frame 9, and the movable end of the buffer 12 faces the limit block 13 fixed to the driving shaft 11. When the two connecting frames 9 move toward each other, the buffer 12 can be placed on the limit block 13. By setting the buffer 12 and the limit block 13 to cooperate, the problem of clamping damage to the paper product 14 when the two clamps 10 are clamped quickly can be prevented to a certain extent, thereby achieving effective protection of the paper product 14 during the clamping process.

[0038] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

[0039] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
