Technical Field

[0001] The utility model relates to the technical field of wood-plastic environmentally friendly pencil processing equipment, in particular to an automatic cutting device for wood-plastic environmentally friendly pencils. Background Art

[0002] Wood-plastic pencils are made of wood and plastic as the main raw materials through a certain processing technology. This type of pencil has the dual advantages of wood and plastic, such as light weight, durability, and not easy to break. At the same time, it can also effectively reduce the consumption of wood and has a certain positive effect on environmental protection.

[0003] During the processing and cutting of the WPC pencils, the WPC pencils are transported by two relatively rotating conveying wheels. At the same time, a rotary cutter is installed on the side of the conveying wheel. When the rotary cutter rotates close to the WPC pencil, it can form an extrusion and cutting effect on the WPC pencil, thus realizing the automatic cutting operation of the WPC pencil.

[0004] During actual operation, since the rotary cutter is always protruding from the outside of the conveyor wheel, the cutting of the wood-plastic pencil by the rotary cutter relies more on the characteristic of the smaller rotation distance between the two rotary cutters to squeeze the wood-plastic pencil and cause it to break. The fracture surface of the wood-plastic pencil is uneven, and a large number of broken small fragments are generated in this process. Based on this, an automatic cutting device for wood-plastic environmentally friendly pencils is provided. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figures 1 to 5In an embodiment of the present invention, an automatic cutting device for wood-plastic environmentally friendly pencils includes a cutting machine body 1 consisting of a base body 101, auxiliary conveying wheels 102, and a cutting conveying wheel 103. The auxiliary conveying wheels 102 are provided with multiple groups, and the cutting conveying wheel 103 is provided with one group. The multiple groups of auxiliary conveying wheels 102 and the one group of cutting conveying wheels 103 are horizontally installed on the top of the base body 101. The output end of the internal driving structure of the base body 101 passes through the top of the base body 101 and is fixedly connected to the bottom of the auxiliary conveying wheels 102 and the cutting conveying wheels 103. The multiple groups of auxiliary conveying wheels 102 and the one group of cutting conveying wheels 103 cooperate to realize the conveying operation of the wood-plastic pencils 3. The inner and outer sides of the cutting conveying wheel 103 are provided with cutting components 2, which are used to realize the cutting operation of the wood-plastic pencils 3.

[0029] The cutting component 2 includes a rotary cutting unit and an extrusion unit;

[0030] The peeling unit rotates with the cutting conveying wheel 103. When the peeling unit rotates to be close to and perpendicular to the WPC pencil 3, the squeezing unit provides squeezing force to the peeling unit, so that the cutting blade 204 in the peeling unit moves horizontally to cut the WPC pencil 3, thereby achieving a smooth cut on the WPC pencil 3.

[0031] The rotary cutting unit includes a convex arc seat 201, a through hole 202, a convex expansion slot 203, a cutting knife 204, a limit block 205, a reset spring 206, and a fastening bolt 210;

[0032] A convex mounting groove 104 is formed on the top of the cutting and conveying wheel 103. The convex mounting groove 104 passes through one side of the cutting and conveying wheel 103. Threaded holes 105 are symmetrically formed on the bottom of the inner wall of the convex mounting groove 104.

[0033] The through holes 202 are symmetrically formed at the top of the convex arc seat 201 and extend to the bottom of the convex arc seat 201. The convex arc seat 201 is inserted into the inner side of the convex mounting groove 104. The fastening bolts 210 pass through the through holes 202 and are threadedly connected to the threaded holes 105 to achieve the installation and fixation of the convex arc seat 201 and the cutting and conveying wheel 103.

[0034] The convex expansion slot 203 is formed inside the convex arc seat 201 and passes through both sides of the convex arc seat 201. The limit blocks 205 are symmetrically fixed to the two ends of the outer wall of the cutting knife 204. The cutting knife 204 is slidably connected to the inner side of the convex expansion slot 203 through the limit blocks 205. The reset spring 206 is distributed between the side of the limit block 205 and the side of the inner wall of the convex expansion slot 203.

[0035] The extrusion unit includes a Z-shaped fixing frame 207, a connecting column 208, and a fixing cam 209;

[0036] A circular cavity 106 is formed inside the cutting and conveying wheel 103, and the circular cavity 106 is connected to the convex mounting groove 104;

[0037] The Z-shaped fixing frame 207 is fixedly mounted on the top of the machine base 101 and is close to the cutting and conveying wheel 103. The connecting column 208 is fixed to the bottom end of the horizontal portion of the top of the Z-shaped fixing frame 207 and passes through the cutting and conveying wheel 103 to the inside of the circular cavity 106. The fixing cam 209 is fixed to the bottom end of the Z-shaped fixing frame 207 and is distributed inside the circular cavity 106.

[0038] One side of the cutting blade 204 extends to the inside of the circular cavity 106 and fits in with the side of the fixed cam 209, and the side of the cutting blade 204 that contacts the fixed cam 209 is an arc structure;

[0039] The protrusion of the fixed cam 209 faces the symmetrical center line of the two cutting and conveying wheels 103 and is perpendicular thereto.

[0040] In this embodiment, it should be noted that each set of auxiliary conveying wheels 102 and cutting conveying wheels 103 includes two auxiliary conveying wheels 102 and two cutting conveying wheels 103, respectively, and the two conveying wheels in each set of auxiliary conveying wheels 102 and cutting conveying wheels 103 rotate in opposite directions, thereby realizing the conveying operation of the wood-plastic pencil 3. Since the internal driving structure of the machine base body 101 is a conventional structure, it is not described in detail.

[0041] In the process of transporting the wood-plastic pencil 3 by the cutting and conveying wheel 103, the cutting and conveying wheel 103 can drive the convex knife seat 201 and the cutting knife 204 to rotate as a whole and approach the wood-plastic pencil 3. When the convex knife seat 201 and the cutting knife 204 are close to the middle of the two cutting and conveying wheels 103, one side of the cutting knife 204 contacts the protruding part of the fixed cam 209. At this time, the cutting knife 204 running in a circular motion is squeezed by the protruding part of the fixed cam 209, causing the cutting knife 204 to move horizontally and protrude to the convex part. The horizontally moving cutting blade 204 outside the convex cutting blade holder 201 and the cutting and conveying wheel 103 punches and cuts the wood-plastic pencil 3. The two symmetrically distributed cutting blades 204 cooperate with each other to achieve the cutting operation of the wood-plastic pencil 3. After that, the cutting and conveying wheel 103 continues to rotate, and the cutting blade 204 moves away from the protruding part of the fixed cam 209. At this time, the cutting blade 204 will be reset and retracted into the inside of the convex cutting blade holder 201 under the elastic force of the reset spring 206. Then, the reciprocating operation can achieve automatic cutting of the wood-plastic pencil 3.

[0042] Due to the retractable structure of the cutting blade 204, the cutting blade 204 mainly cuts the WPC pencil 3 by punching. Compared with the traditional cutting blade 204 that breaks the WPC pencil 3 by squeezing, the cutting surface of the WPC pencil 3 is smoother, and the generation of fine particles is reduced, which can further improve the cutting quality of the WPC pencil 3.

[0043] Please refer to Figures 1 to 4 The two groups of cutting components 2 on the two cutting and conveying wheels 103 are symmetrically distributed with the symmetry center line of the two cutting and conveying wheels 103 as the center, and the circumferential length of the cutting and conveying wheels 103 matches the cutting length of the wood-plastic environmentally friendly pencil.

[0044] In this embodiment, two symmetrically arranged cutting assemblies 2 are used. When the two cutting blades 204 are driven by the two cutting and conveying wheels 103 to rotate close to each other, the cutting blades 204 are squeezed by the protruding portion of the fixed cam 209 and move outward synchronously, thereby achieving synchronous punching of both sides of the WPC pencil 3 and making the force applied to the WPC pencil 3 more uniform.

[0045] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
