Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described more fully hereinafter with reference to the accompanying drawings. The preferred embodiments of the present invention are illustrated in the accompanying drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. These embodiments are provided so that this disclosure will be thorough and complete.

It will be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.

The first and the second do not represent specific quantity and sequence, and are only used for distinguishing names.

It should be noted that the actual structure of the folding machine is numerous and complicated, in order to clearly illustrate the structure related to the object of the present invention, the description and the drawings only explain and show a part of the structure of the folding machine, and other structures unrelated to the object of the present invention adopt the same structure as the existing folding machine.

Referring to fig. 1 and 2, the folding machine of the present invention includes two parallel folding rollers 1, and a plurality of paper bearing members 2 are disposed below the folding rollers. In operation of the folder, two successive sheets of paper 12 from different sources are passed in succession through the nip of two folding rollers 1, and the two folding rollers 1 are rotated in opposite directions in synchronism to slit and fold the sheet of paper passing through the nip into a single sheet of paper. The folded paper material falling from the folding roller 1 is stacked on the paper support 2.

All the sheet bearers 2 are aligned in a direction parallel to the axis of the folding roller 1 and are fixed to a first overall link 3. The connection mode of the paper bearing member 2 and the first general connecting rod 3 can be welding, screw connection and the like. The paper carrier 2 is driven by a first overall connecting rod 3 to reciprocate up and down between the folding roller 1 and the conveying belt 4. The first main connecting rod 3 is connected with a transmission belt 5, and the transmission belt 5 drives the first main connecting rod 3 to reciprocate up and down. The belt 5 may be a belt. Besides the transmission belt, other mechanisms such as a gear rack mechanism or a linear motor can be adopted to drive the first main connecting rod 3 to reciprocate up and down. The first total link lever 3 drives the sheet receiving member 2 to gradually descend as the height of the sheet stack stacked on the sheet receiving member 2 increases.

The conveyor belt 4 is disposed at a position farther below the folding roller 1. Whenever the paper stacked on the paper support 2 reaches the number of one stack of finished paper, the paper support 2 is moved down to a position near the beginning of the conveying belt 4 as shown in fig. 3.

A plurality of pushers 6 are provided near the beginning of the conveyor belt 4. All the pushers 6 are aligned in a direction parallel to the axis of the folding roller 1 and are fixed to a second overall connecting rod 7. The connection mode of the paper pushing member 6 and the second general connecting rod 7 can be welding, screw connection and the like. The pusher 6 is reciprocated in the horizontal direction toward or away from the conveyor belt 4 by the second overall connecting rod 7. When the sheet pusher 6 moves in a direction approaching the conveying belt 4, as shown in fig. 4 to 5, the entire stack of sheets 8 stacked on the sheet bearing member 2 is pushed onto the conveying belt 4 by the sheet pusher 6. The second general connecting rod 7 is connected with a cylinder 9, and the cylinder 9 drives the second general connecting rod 7 to reciprocate. Besides the cylinder, other mechanisms such as a rack and pinion mechanism or a linear motor can be used for driving the second main connecting rod 7 to reciprocate.

In order to ensure that neither the sheet holding member 2 nor the first overall link 3 interferes with the movement of the sheet pushing member 6 and the second overall link 7 over the entire stroke range of the reciprocating movement of the sheet holding member and the sheet pushing member, as shown in fig. 6, the interval of arrangement of the sheet holding member 2 on the first overall link 3 and the interval of arrangement of the sheet pushing member 6 on the second overall link 7 are staggered from each other. Thus, in the process of pushing the paper shown in fig. 3 to 5, the paper pushing member 6 does not collide with the paper receiving member 2. On the other hand, as shown in fig. 3, with the direction in which the paper is conveyed by the conveying belt 4 (i.e., the direction indicated by the arrow in fig. 3) as a reference direction, the first total connecting rod 3 is located upstream of the pusher 6, and the second total connecting rod 7 is located downstream of the paper receiver 2. In this way, no matter where the paper receiver 2 and the paper pusher 6 move, the paper receiver 2 and the first overall link lever 3 do not collide with the paper pusher 6 and the second overall link lever 7. Therefore, whenever the pusher 6 pushes the paper materials stacked on the paper bearing member 2 away from the paper bearing member as shown in fig. 5, the paper bearing member 2 can be immediately moved upward to return to the position shown in fig. 1 without waiting for the pusher 6 to return to the position shown in fig. 1, and the working efficiency of the folding machine is improved.

It should be noted that the means for driving the movement of the first general connecting rod 3, such as the belt 5, do not necessarily have to be arranged upstream of the pusher 6; the mechanism for driving the movement of the second general connecting rod 7, for example the pneumatic cylinder 9, does not necessarily have to be arranged downstream of the support 2. For example, the mechanism for driving the first total connecting rod 3 to move is connected to two ends of the first total connecting rod 3, the mechanism for driving the second total connecting rod 7 to move is connected to two ends or the middle of the second total connecting rod 7, and as long as the two ends of the first total connecting rod 3 exceed the length of the second total connecting rod 7 by a sufficient length, the mechanism for driving the first total connecting rod 3 to move can be ensured not to collide with the paper pushing part 6 and the second total connecting rod 7, and the mechanism for driving the second total connecting rod 7 to move can not collide with the paper bearing part 2 and the first total connecting rod 3.

As a best mode, referring to fig. 1 and 6, a plurality of connecting plates 10 are connected to the top of the paper bearing member 2, the connecting plates 10 are arranged along the direction parallel to the axis of the folding roller 1, and the arrangement intervals of the connecting plates 10 and the arrangement intervals of the paper pushing members 6 on the second connecting bar 7 are staggered. Therefore, the supporting area of the paper material by the paper supporting member 2 is increased by the connecting plate 10, and the connecting plate 10 and the paper pushing member 6 do not generate motion interference.

As a preferred embodiment, referring to fig. 6 and 7, the folding machine has a plurality of conveyor belts 4 arranged in parallel with a space 11 between the conveyor belts 4, and when the sheet pushing member 6 moves toward the conveyor belts 4, the sheet pushing member 6 enters the space 11 between the conveyor belts as shown in fig. 6 and 7. Therefore, the pushing force of the paper pushing piece 6 to the paper stack can be stably connected with the friction pulling force of the conveying belt 4 to the paper stack, the phenomenon that the stacked paper stack is inclined and inclined due to sudden change of stress in the transferring process is avoided, and the paper stack is stably transferred to the conveying belt 4 from the paper bearing piece 2. The speed of the pusher 6 moving toward the conveyor belt 4 preferably coincides with the speed of the paper being carried by the conveyor belt 4.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, various changes and modifications can be made without departing from the spirit of the present invention, and these changes and modifications are all within the scope of the present invention. The protection scope of the present invention should be subject to the appended claims.
