Description

Technical Field

[0001] The utility model belongs to the technical field of food packaging paper production equipment, and particularly relates to a cutter roller for food packaging paper production. Background Art

[0002] Food packaging paper is a packaging product mainly made of pulp and paperboard, which needs to meet the requirements of being non-toxic, oil-resistant, waterproof and moisture-proof, sealed, etc., and is paper used for packaging food that meets the food packaging safety requirements. In the process of cutting existing food packaging paper, a cutter roller is required.

[0003] When disassembling and assembling the cutter roller used in the processing of existing food packaging paper, bolts are generally used. However, when the bolts are installed alone, the cutter roller cannot be stabilized, resulting in easy jitter of its cutting edge. Therefore, after installation and fixation, additional equipment is required to reinforce the cutter roller to avoid offset of the cutter roller. For this reason, it is necessary to propose a cutter roller for food packaging paper production. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a cutter roller for food packaging paper production to solve the technical problem of unstable installation of the existing cutter roller.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A cutter roller for food packaging paper production includes an installation roller. An installation groove is formed on the lower surface of the installation roller. A cutting knife is inserted into the installation groove. Two support blocks are fixedly connected to the outer side wall of the top end of the cutting knife located in the installation groove. Two sliding holes are formed through the notch of the installation groove. Two threaded holes are formed through the groove wall of the installation groove. Threaded grooves are formed on two support blocks corresponding to the two threaded holes. Two threaded rods are commonly threadedly connected in the two threaded holes and the two threaded grooves. One end of each of the two threaded rods extends through the installation roller, and one end of each of the two threaded rods located outside the installation roller is rotatably connected to a limit plate through a bearing. Support plates are fixedly connected to the positions of the two limit plates corresponding to the two sliding holes. Two support rods are fixedly connected to the side walls of the opposite sides of the two support plates.

[0007] As a preferred scheme of the utility model, one end of each of the two threaded rods respectively penetrates through the corresponding limit plate and extends outwards and is fixedly connected with a rotating handle.

[0008] As a preferred scheme of the utility model, one end of each of the two support plates away from the limit plate respectively penetrates through the corresponding sliding hole and extends into the installation groove, and the upper surfaces of the two support plates located in the installation groove abut against the lower surfaces of the two support blocks.

[0009] As a preferred embodiment of the present utility model, the side walls of the four support rods facing each other are all inclined, and the four support rods respectively abut against the two side walls of the cutting knife.

[0010] As a preferred embodiment of the present utility model, the lower end of the cutting knife penetrates through the notch of the installation groove and extends outside the installation roller.

[0011] Compared with the prior art, the beneficial effects of a knife roller for food packaging paper production of the present utility model are as follows: When in use, the top end of the cutting knife is inserted into the installation groove, and the threaded rod is rotated. The threaded rod is threadedly connected with the threaded groove to fix the support block and the cutting knife. At the same time, the threaded rod will drive the support plate and the support rod to insert into the installation groove. The support plate supports the support block, and the support rod supports the cutting knife by abutting against the two side walls of the cutting knife, thereby avoiding the phenomenon of the cutting knife shaking.

For example, it can be a fixed connection, an integral connection, or a detachable connection; it can be the communication inside two elements; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific situations.

[0020] See Figures 1-3 As shown, a cutter roller for food packaging paper production includes an installation roller 1. An installation groove 2 is formed on the lower surface of the installation roller 1. A cutting knife 3 is inserted into the installation groove 2. The lower end of the cutting knife 3 penetrates through the notch of the installation groove 2 and extends outside the installation roller 1. Two support blocks 4 are fixedly connected to the outer side wall of the top end of the cutting knife 3 located inside the installation groove 2. Two sliding holes 5 are penetrated through the notch of the installation groove 2. Two threaded holes 6 are penetrated through the groove wall of the installation groove 2. Thread grooves 7 are formed on two support blocks 4 corresponding to the positions of the two threaded holes 6. Two threaded rods 8 are commonly threadedly connected in the two threaded holes 6 and the two thread grooves 7. One end of each of the two threaded rods 8 penetrates and extends outside the installation roller 1, and one end of each of the two threaded rods 8 located outside the installation roller 1 is rotatably connected with a limiting plate 9 through a bearing. Support plates 10 are fixedly connected to the positions of the two limiting plates 9 corresponding to the two sliding holes 5. Two support rods 11 are fixedly connected to the side walls of the two support plates 10 facing each other.

[0021] One end of each of the two threaded rods 8 penetrates through the corresponding limiting plate 9 and extends outwards and is fixedly connected with a rotating handle 12. The threaded rod 8 can be rotated by rotating the rotating handle 12.

[0022] One end of each of the two support plates 10 away from the limiting plate 9 penetrates through the corresponding sliding hole 5 and extends into the installation groove 2, and the upper surface of the two support plates 10 located inside the installation groove 2 abuts against the lower surface of the two support blocks 4, so that the support plates 10 can support the support blocks 4.

[0023] The side walls of the four support rods 11 facing each other are all inclined, and the four support rods 11 respectively abut against the two side walls of the cutting knife 3, so that the support rods 11 can completely abut against the outer side wall of the cutting knife 3 to clamp and fix it.

[0024] When the embodiment of the utility model is in use, the cutting knife 3 and the supporting block 4 are inserted into the installation groove 2 and abutted against the top groove wall of the installation groove 2. At this time, the threaded rod 8 can be rotated by rotating the handle 12. The threaded rod 8 moves into the threaded hole 6 and the threaded groove 7 and is threadedly connected therewith. Thus, the threaded rod 8 will install and fix the supporting block 4 and the cutting knife 3. During the movement of the threaded rod 8, the supporting plate 10 and the supporting rod 11 will be driven to move into the installation groove 2. The supporting plate 10 supports and clamps the supporting block 4, and the supporting rod 11 clamps the periphery of the cutting knife 3. Furthermore, after installation, the supporting block 4 and the cutting knife 3 are reinforced, so as to prevent the cutting knife 3 from shaking during use and affecting its normal use.

[0025] The above shows and describes the basic principle of the invention. The above is only the preferred embodiment of the invention, and is not used to limit the invention. The descriptions in the above embodiments and the specification only illustrate the principle of the invention. Without departing from the scope of the invention, any modifications, equivalent replacements and improvements made within the spirit and scope of the invention shall be included in the protection scope of the invention.
