Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paper equipment, and particularly relates to a double-sided knife comb structure. Background Art

[0002] The paper cutting knife on the paper separating and creasing machine longitudinally cuts the corrugated cardboard into certain sizes. During cutting, the paper cutting knife exerts a downward pressure on the cardboard, and at this time, the knife comb below the cardboard will lift the cardboard to ensure smooth cutting. Since the lower surface of the cardboard will be exposed when the paper cutting knife cuts, friction will be generated between the cardboard and the knife comb, resulting in the knife comb being unusable after being worn for a period of time. Since most of the knife combs on the market are fixed, and the size of the corrugated cardboard determines that the paper cutting knife cuts frequently in the same area, often a whole set of knife combs needs to be replaced due to severe local wear, with low utilization rate and short service life.

[0003] There is also a movable knife comb on the market currently, which can improve the service life of the knife comb by making the knife comb move to make the wear uniform. However, the cutting board of this kind of knife comb is made of relatively soft material and is more likely to be worn during cutting. Often, the cutting board is damaged but the wear of the knife comb blades is not serious. At this time, when replacing the knife comb, the utilization rate of the knife comb is very low, which is a waste to users. This single-sided knife comb does not fully utilize the advantages of the movable knife comb.

[0004] Therefore, there is an urgent need to provide a double-sided knife comb structure to overcome the above defects. Summary of the Utility Model

[0005] The main purpose of the utility model is to provide a double-sided knife comb structure, which overcomes the problem of inconsistent wear between the cutting board and the knife comb blades, gives full play to the advantages of the movable knife comb, greatly improves the utilization rate of the knife comb, further extends the service life of the knife comb, reduces the loss of users, and reduces the production cost of corrugated cardboard.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A double-sided knife comb structure includes: a knife comb support with one side detachably and turnably clamped into the guide rail seat in the up-and-down direction and a clamping and fixing groove formed on the other side; a plurality of knife comb blades regularly installed in an up-and-down symmetric structure with the middle surface in the up-and-down direction as the symmetry axis, parallel to each other and installed at intervals in the length direction of the double-sided knife comb structure; and a cutting board that clamps and fixes one end of the plurality of knife comb blades and fixes the plurality of knife comb blades in the clamping and fixing groove.

[0008] Preferably, on one side edge of the upper and lower surfaces of each knife comb blade, clamping grooves for clamping and fixing with the cutting board are symmetrically formed.

[0009] Preferably, the cutting board includes an upper / lower cutting board;

[0010] The upper / lower chopping boards are respectively clamped with the card slots of each of the knife comb blades. After assembly, the upper surface of the upper chopping board is consistent with the upper surface formed by connecting the upper ends of each of the knife comb blades, and the lower surface of the lower chopping board after assembly is consistent with the lower surface formed by connecting the lower ends of each of the knife comb blades.

[0011] Preferably, there is a spacing of 0.5 mm - 1.5 mm between two adjacent knife comb blades, and the gaps between every two knife comb blades are arranged along the length direction of the chopping board.

[0012] Preferably, the thickness of each knife comb blade is 0.5 mm - 1.5 mm.

[0013] Preferably, on both side surfaces of one end of the knife comb holder that is clamped into the guide rail seat, grooves corresponding to clamping the guide rail seat are recessed.

[0014] Preferably, one end of the knife comb holder formed with the two grooves is formed in a T shape.

[0015] Preferably, a clamping and positioning portion that is clamped into the groove is formed on the guide rail seat.

[0016] The beneficial effects of the present utility model are as follows: A plurality of the knife comb blades are designed in an up-and-down symmetric structure with the middle surface in the up-and-down direction as the axis of symmetry, and are fixed in the clamping and fixing grooves of the knife comb holder by the chopping board. When the knife comb blades are worn, the knife comb holder can be disassembled from the guide rail and then flipped and clamped back onto the knife comb holder, which improves the product utilization rate. At the same time, the up-and-down symmetric structure design ensures the consistency of the wear degree of the chopping board and the knife comb blades during use, further improving the utilization rate of the knife comb. This design enables the product to overcome the problem of inconsistent wear between the chopping board and the knife comb blades, gives play to the advantages of the mobile knife comb, greatly improves the utilization rate of the knife comb, further extends the service life of the knife comb, reduces the loss of users, and reduces the production cost of corrugated cardboard.

[0025] Please refer to Figure 1 , a double-sided knife comb structure of this embodiment includes: a guide rail seat 1, a knife comb holder 2, several knife comb blades 3, and a cutting board 4. Among them, the guide rail seat 1 is installed below the cardboard passing plate 5. One side of the knife comb holder 2 is detachably and turnable up and down and is clamped into the guide rail seat 1, and a clamping and fixing groove 21 is formed on the other side. Several of the knife comb blades 3 are regularly installed in an upper and lower symmetric structure with the middle surface in the up and down direction as the symmetry axis, are parallel to each other and are installed in the length direction of the double-sided knife comb structure at intervals. The cutting board 4 is clamped and fixed at one end of each knife comb blade 3 and fixes each knife comb blade 3 in the clamping and fixing groove 21.

[0026] In a preferred embodiment, a clamping and positioning portion 11 is formed on the guide rail seat 1. The clamping and positioning portion 11 is formed by inwardly recessing two grooves with different depths on one surface of the guide rail seat. One of the grooves is located below the paper passing board 5 and forms a clamping chute with the clamping and positioning portion 11, and the knife comb support 2 is clamped in the clamping chute.

[0027] On both sides of one end of the knife comb support 2 that is clamped into the guide rail seat 1, grooves corresponding to the clamping and positioning portion 11 of the guide rail seat 1 are recessed. One end of the knife comb support 2 where the two grooves are formed is formed in a T shape. The two symmetrically protruding ends of the T-shaped structure are clamped into a corresponding groove of the guide rail seat 1 when flipped. The outer side of the clamping fixing groove 21 is installed on another groove of the guide rail seat 1. The depth of the clamping fixing groove 21 is greater than the height of the side of the end forming the T-shaped structure in the same direction. This structural design enables the knife comb support 2 to slide well on the guide rail seat 1 after being clamped and also have good clamping strength with the guide rail seat 1.

[0028] On one side edge of the upper and lower surfaces of each knife comb blade 3, clamping slots for clamping and fixing with the cutting board 4 are symmetrically formed. There is a 1-mm spacing between adjacent two knife comb blades 3, and the gaps between every two knife comb blades 3 are arranged along the length direction of the cutting board 4. The thickness of each knife comb blade 3 is 1 mm. This thickness design gives the product a certain elasticity in the thickness direction. Specifically, the spacing range between the two knife comb blades 3 is preferably 0.5 mm - 1.5 mm, and the preferred value of the thickness of each knife comb blade 3 is 0.5 mm - 1.5 mm. More specifically, the cutting board 4 includes an upper / lower cutting board 41 / 42; the upper / lower cutting boards 41 / 42 are respectively clamped with the clamping slots of each knife comb blade 3. The upper surface of the assembled upper cutting board 41 is consistent with the upper surface formed by connecting the upper end sides of each knife comb blade 3, and the lower surface of the assembled lower cutting board 42 is consistent with the lower surface formed by connecting the lower end sides of each knife comb blade 3. The grooves formed on each knife comb blade 3 are clamped and fixed by corresponding clamping slide rails formed on one side surface of the upper cutting board 41 and the lower cutting board 42. During assembly, the upper / lower cutting boards 41 / 42 are fixed on the metal support 2 with glue, and the upper cutting board 41 and the lower cutting board 42 are symmetrically installed on the upper / lower surfaces of the whole assembled by each knife comb blade 3, and they are designed to be in the same plane after upper / lower surface assembly, effectively preventing damage to the corrugated paper surface caused by uneven paper passing surfaces.

[0029] As can be seen from the above description, in a double-sided knife comb structure of the present utility model, each of the knife comb blades 3, the upper chopping board 41, the lower chopping board 42 and the knife comb holder 2 are assembled into an upper and lower symmetric structure with the middle plane of the assembled whole as the axis of symmetry, and the knife comb holder 2 can slide out of the guide rail seat 1 and flip 180° to be snap-connected back into the guide rail seat 1, so that when one side of the product is damaged, it can be flipped over and used, improving the utilization rate of the product. Moreover, the symmetric structural design ensures the usability of both the front and back sides of the product while also ensuring the consistency of wear between the chopping board 4 and the knife comb blades 3, thereby improving the utilization rate of the knife comb.

[0030] In summary, the present utility model overcomes the problem of inconsistent wear between the chopping board and the knife comb blades, gives full play to the advantages of the mobile knife comb, greatly improves the utilization rate of the knife comb, further extends the service life of the knife comb, reduces the loss of users, and reduces the production cost of corrugated cardboard.
