DETAILED DESCRIPTION

[0025] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0026] See also Figure 1-Figure 9 , the present invention provides the following technical solutions: Embodiment 1: In this embodiment, the disclosed Figure 1-Figure 2The scheme shown is to solve the problems existing in the prior art, comprising a cutter 1 and a cutter holder 2 for mounting the cutter 1. The cutter holder 2 is vertically slidably mounted in a frame 3 of a cutting device through a driver. A pressing block 4 is arranged on the side of the cutter 1, wherein the pressing block 4 and a driving mechanism connected to its top end form a leveling mechanism. The driving mechanism drives the pressing block 4 to move synchronously along a direction parallel to the movement of the carpet through the movement of the cutter 1. The driving mechanism comprises a connecting rod 5 and a positioning plate 6 rotatably connected to its top end. The positioning plate 6 is used to be mounted on the cutter holder 2. At the same time, the bottom end of the connecting rod 5 is also rotatably mounted on the pressing block 4. Moreover, two adjacent connecting rods 5 are in a crossed and non-interfering state. At the same time, the bottom end of the pressing block 4 is initially located below the bottom end of the cutter 1. The driver includes a hydraulic or electric drive device, which enables the knife holder 2 to move synchronously in the frame 3, so as to cut the carpet on the equipment platform. When the bottom end of the cutter 1 does not contact the carpet, the lower end surface of the pressing block 4 will first contact the carpet. Therefore, in the subsequent movement of the cutter 1, the pressing block 4 will play a role in pressing to limit the movement and maintain the cutting stability. In the process of the cutter 1 continuing to move following the knife holder 2, the connecting rod 5 will be pressed and tilted and drive the pressing block 4 to move in a direction away from each other, thereby achieving a leveling effect before and after cutting the carpet.

[0027] like Figure 3 As shown, the problem to be solved by this scheme is mainly to prevent the pressing block 4 from pulling and causing the carpet to be misplaced due to the static friction between the pressing block 4 and the carpet during the return process. A roller 7 is also provided at the position where the lower end surface of the pressing block 4 contacts the carpet. The roller 7 is unidirectionally rotatable and arranged at the bottom end of the pressing block 4. After the unidirectionally rotating roller 7 is adopted, when the cutter 1 moves downward and pulls the pressing block 4 in a direction away from each other, the roller 7 is in a locked state, thereby achieving a higher effect of pulling and leveling the carpet. When the cutter 1 moves upward and pulls the pressing block 4 in a direction approaching each other, the roller 7 can reduce the static friction between the pressing block 4 and the carpet by rotating, thereby preventing the carpet from being misplaced due to the movement of the pressing block 4 after the cutting is completed.

[0028] Embodiment 2: The main problem to be solved in this embodiment is the hair scraps that are easily generated during the cutting process, and the high temperature that is generated when the blade repeatedly cuts the composite carpet material and accelerates aging. The overall solution is as follows: Figure 4As shown, a horizontally distributed pressure rod 8 is also installed on the pressure block 4, wherein the pressure rods 8 on two adjacent pressure blocks 4 are adjacently distributed up and down, wherein the pressure rod 8 is used to cooperate with the pressure block 4 to level the carpet, and an air cavity 9 is opened inside the pressure rod 8, and the air cavity 9 is connected with the air hole 10 distributed in the direction of the cutter 1 and opened on the surface of the pressure rod 8, and the air cavity 9 is also connected with the air flow mechanism, wherein the air flow mechanism generates airflow through the movement of the cutter 1 and acts on the incision or the blade of the carpet, and the air flow mechanism affects the air cavity 9 by blowing or sucking air, so the air hole 10 connected thereto will synchronously blow out airflow or produce a negative pressure adsorption effect, and the blowing airflow can act on the blade of the cutter 1 or the incision of the carpet during the cutting work to achieve a cooling effect, and can also collect hair scraps at the incision by negative pressure suction. The two can be carried out continuously in a work process of the cutter 1, or can be carried out alternately in a work process, for example, the cutter 1 moves down to inhale air to clean debris, and blows air when the cutter 1 moves up to cool the blade.

[0029] Embodiment 3: This embodiment further discloses the composition of the above solution in detail. Figure 6-Figure 7 The air flow mechanism includes a vertical cylinder 12 fixed under the positioning plate 6, wherein the internal air pressure space of the vertical cylinder 12 is communicated with the hollow structure inside the pressure block 4 through the air pipe 11, and the hollow structure is also communicated with the air cavity 9. The internal air pressure space of the vertical cylinder 12 is composed of two valve plates 14 separating the internal space of the vertical cylinder 12. The two spaces are respectively the space between the valve plates 14 and the space between the outer side of the valve plate 14 and the inner wall of the vertical cylinder 12. The outer surface of the valve plate 14 is connected to the vertical rod 13, and the vertical rod 13 elastically slidably mounted at the end of the vertical cylinder 12 slides and fits on the connecting rod 5. When the connecting rod 5 is deflected, it will compress and drive the vertical rod 13 to move synchronously, and the two vertical rods 13 in a vertical tube 12 will drive the two valve plates 14 to move synchronously in the opposite direction. Therefore, the space between the valve plates 14 and the space between the valve plates 14 and the inner wall of the vertical tube 12 will be in different air pressure states as the movement state changes. The connection state between the air pipe 11 and the air pressure space can be adjusted, such as the adjustment of one-way connection and two-way connection / adjustment of the input port or output port connection, so that the movement of the valve plate 14 can make the air hole 10 in a blowing state or a negative pressure suction state respectively.

[0030] Embodiment 4: The solution disclosed in this embodiment is an expansion on the basis of the above solution. The actual production can be adjusted as needed. The effect to be achieved in the solution is to provide more blade movement dimensions to improve the cutting effect of the carpet, such as Fig. 9As shown, the middle section of the top vertical rod 13 is a twisted rod section, which is threadedly connected to the top wall of the vertical tube 12. At the same time, a cam 19 is also installed on the upper half of the vertical rod 13. The cam 19 drives the vibration plate 15 to knock on the cutter 1 by intermittently knocking on the force plate 16 and through the cross bar 17. The cross bar 17 is horizontally slidably installed on the vertical plate 18 through an elastic member, and the vertical plate 18 is fixed on the positioning plate 6. When the vertical rod 13 located above is in a state of vertical movement under force, the vertical rod 13 will be in a rotating state under the effect of thread transmission, and the bottom end of the vertical rod 13 can rotate on the valve plate 14. When rotating, it will drive the cam 19 to rotate synchronously and intermittently knock on the force plate 16, so that the vibration plate 15 knocks on the cutter 1 reciprocatingly, so that the cutter 1 in operation is in a vibrating state and the cutting efficiency is improved.

[0031] The cutting method according to the above embodiment comprises the following steps: Step 1: Install the leveling mechanism, where the leveling mechanism is a general term for the positioning plate 6, the connecting rod 5 and the pressing block 4, the three of which are connected to the knife seat 2 through the positioning plate 6, and the initial height of the pressing block 4 is adjusted by adjusting the installation height; Step 2: Debugging the leveling mechanism, the debugging method includes but is not limited to trial cutting operations on carpet materials in multiple material forms, such as wool blankets, rubber blankets or composite carpets with metal materials, and adjusting the connection state of the air pipe 11 and the vertical cylinder 12 according to the difference between the debugging processing object and the formal processing object; Step 3: Clean the hair residue in the vertical cylinder 12 or the air pipe 11. The cleaning cycle is adjusted according to the operating intensity of the cutting device and the processing object.

[0032] The connection state of the air pipe 11 and the vertical tube 12 is changed by the following method: Method 1: Make the two output ends of the air pipe 11 connected to the input ends or output ends of the two air pressure spaces respectively, so that the movement of the valve plate 14 can produce different air pressure effects on the air cavity 9; Method 2: Changing the connection state of the two input ends of the air pipe 11, such as installing a one-way valve; Method three: connect the input end and the output end of the air pressure space to the input end of the air pipe 11.
