Technical Field

[0001] This utility model relates to the field of printing equipment technology, specifically to a printing press slitting and fixing structure. Background Technology

[0002] Printing is the process of transferring an approved printing plate onto printing paper using printing machinery and specialized inks. During printing, the printing paper is glued to a paper tube at one end and wound into a printing roll. The portion glued to the roll is unusable. When the printing paper on the roll is almost used up, the portion glued to the paper tube needs to be cut off, and then new printing paper from a new roll is attached to the cut end of the original printing paper to continue printing.

[0003] Although existing paper cutting methods utilize the tension of the paper's tight structure for cutting, paper movement still occurs during the cutting process. This can lead to incomplete cuts, uneven cuts, and, more importantly, damage to the paper's tension, resulting in decreased product quality. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a printing press cutting and fixing structure that can fix the printing paper before cutting, thus avoiding problems such as uneven cutting and damage to the paper's tension.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A printing press slitting and fixing structure includes a frame with opposing side plates and a support plate between the side plates. The support plate has a cutter groove for a cutter to extend from. Paper pressing assemblies are arranged on one or both sides of the cutter groove along the direction of paper movement. Each paper pressing assembly includes a paper pressing component and a driving component that drives the paper pressing component away from or towards the support plate. The paper is fixed by the paper pressing component and the driving component, and then the cutter is inserted into the cutter groove to cut the paper, thus solving problems such as uneven cutting and damage to the paper tension.

[0007] As a preferred embodiment, paper pressing assemblies are provided on both sides of the cutter groove along the paper moving direction; the paper pressing assemblies include a first paper pressing assembly and a second paper pressing assembly, the first paper pressing assembly includes a first paper pressing element and a first driving element, and the second paper pressing assembly includes a second paper pressing element and a second driving element.

[0009] As a preferred embodiment, there are two first driving members, which are spaced apart along the length of the first paper pressing member, and two second driving members, which are spaced apart along the length of the second paper pressing member.

[0010] As a preferred embodiment, the support plate is provided with a first mounting plate and a second mounting plate at intervals along the direction of paper movement, the first mounting plate and the second mounting plate being on the same side as the first driving member and the second driving member; the support plate is mounted between the side plates via the first mounting plate and the second mounting plate.

[0011] As a preferred embodiment, the length direction of the first and second paper pressing components is perpendicular to the direction of movement of the printing paper.

[0012] As a preferred embodiment, the support plate is further provided with a first protective shell covering the first paper pressing component and a second protective shell covering the second paper pressing component.

[0027] like Figure 1-3As shown, this utility model discloses a printing press cutting and fixing structure, including a frame 10. The frame 10 has side plates 11 arranged opposite each other, and a support plate 14 is provided between the side plates 11. The support plate 14 is provided with a cutting groove 15 for the cutter to extend out. A paper pressing assembly is provided on one or both sides of the cutting groove 15 along the direction of paper movement.

[0028] Paper pressing assemblies are provided on both sides of the cutter groove 15 along the paper movement direction; the paper pressing assemblies include a first paper pressing assembly and a second paper pressing assembly. The first paper pressing assembly includes a first paper pressing element 20 and a first driving element 23, and the second paper pressing assembly includes a second paper pressing element 30 and a second driving element 33. The first paper pressing element 20 and the first driving element 23 are respectively installed on opposite sides of the support plate 14. The driving end of the first driving element 23 penetrates the support plate 14 and drives and connects to the first paper pressing element 20. The second paper pressing element 30 and the second driving element 33 are respectively installed on the support plate 14. On both sides opposite to the plate 14, the driving end of the first driving member 23 passes through the support plate 14 and drives and connects to the second paper pressing member 30; there are two first driving members 23, which are distributed at intervals along the length direction of the first paper pressing member 20; there are two second driving members 33, which are distributed at intervals along the length direction of the second paper pressing member 30; by setting the first paper pressing assembly and the second paper pressing assembly, the position of the printing paper on both sides of the cutter groove 15 can be more stably fixed, avoiding the movement of the printing paper during cutting.

[0029] In this invention, both the first driving component 23 and the second driving component 33 are cylinders.

[0030] It should be understood that the first driving component 23 and the second driving component 33 can also be a combination of a motor and a lead screw or other driving components, which can satisfy the requirement of driving the paper pressing component away from or close to the pressure support plate 14.

[0031] The support plate 14 is provided with a first mounting plate 24 and a second mounting plate 34 at intervals along the direction of paper movement. The first mounting plate 24 and the second mounting plate 34 are on the same side as the first driving member 23 and the second driving member 33. The support plate 14 is installed between the side plates 11 through the first mounting plate 24 and the second mounting plate 34. The installation stability of the support plate 14 can be improved by setting the first mounting plate 24 and the second mounting plate 34.

[0032] The length direction of the first paper pressing member 20 and the second paper pressing member 30 is perpendicular to the moving direction of the printing paper; by setting them perpendicularly, uneven force can be applied during the cutting of the printing paper, which can prevent tearing.

[0033] The support plate 14 is also provided with a first protective shell 22 covering the first paper pressing component 20 and a second protective shell 32 covering the second paper pressing component 30; the first paper pressing component 20 is provided with a first mounting block 21 on the outer side of both ends along its length direction, and the first protective shell 22 is mounted on the support plate 14 through the first mounting block 21; the second paper pressing component 30 is provided with a second mounting block 31 on the outer side of both ends along its length direction, and the second protective shell 32 is mounted on the support plate 14 through the second mounting block 31; by providing the first protective shell 22 and the second protective shell 32, the first paper pressing component 20 and the second paper pressing component 30 can be protected, thereby improving their service life.

[0034] The cutter groove 15 is inclined at a certain angle to the direction of paper movement; the support plate 14 is inclined at a certain angle to the horizontal plane, and a first guide roller 13 and a second guide roller 14 are provided on the outer side of the support plate 14. The first guide roller 13 is arranged on the lower side of the support plate 14 along the direction of paper movement, and the second guide roller 14 is arranged on the upper side of the support plate 14 along the direction of paper movement. By tilting the cutter groove 15 and the support plate 14, the stress generated on the paper during the cutting process can be reduced, and the printing paper can be cut more easily.

[0035] The method of using this utility model is as follows: the printing paper is passed sequentially through the first guide roller 12, between the first paper pressing component 20 and the support plate 14, between the second paper pressing component 30 and the support plate 14, and the second guide roller 13. When it is necessary to change the paper, the first driving component 23 and the second driving component 33 are activated to drive the first paper pressing component 20 and the second paper pressing component 30 to fix the printing paper. Then, a cutter is used to extend into the cutter groove 15 and cut the printing paper along the cutter groove 15. After the first paper pressing component 20 is released, the new printing paper is passed between the first paper pressing component 20 and the support plate 14 and attached to the cut of the original printing paper. The second paper pressing component 30 is then released to complete the process.

[0036] This utility model provides a driving component and a paper pressing component on the support plate 14. The driving component drives the paper pressing component to press and fix the printing paper on the support plate 14. Then, a cutter is inserted into the cutter slot 15 to cut the printing paper, which can achieve convenient and quick cutting of the printing paper, while making the cut smooth and improving product quality.
