Description

Technical Field

[0001] The invention belongs to the field of cutting and processing equipment, and in particular relates to a machine for synchronously cutting and grooving long strip ultra-thin floors at both ends. Background Art

[0002] At present, in order to meet the laying and splicing requirements of the floor, it is necessary to groove the ends and sides of the floor. The basic principle of the grooves involved is to feed the floor into a groove tool and cut and remove the excess parts to form the required grooves.

[0003] However, for long strips (usually more than 2 meters or longer) and thin (about 1 to 3 cm) of flooring, there are the following difficulties in grooving:

[0004] 1) Due to the characteristics of the floor itself, it is difficult to keep the grooves in a relatively flat state. Therefore, there is a high probability of deviation in the groove position and angle, which directly affects the assembly of the floor;

[0005] 2) During the grooving process, not only can only one end or one side be grooved at a time, but once the transmission is unstable or the cutting force is uneven during cutting, it will cause the groove to slip and the groove depth to be uneven. Therefore, the grooving efficiency and grooving quality cannot meet the processing needs. In addition, if the grooving is carried out one after another, the parallelism of the grooves at both ends cannot be guaranteed. Summary of the invention

[0006] The purpose of the present invention is to overcome the shortcomings of the prior art and provide an improved long strip ultra-thin floor two-end synchronous cutting and grooving machine.

[0007] In order to achieve the above object, the technical solution adopted by the present invention is:

[0008] A machine for synchronously cutting and grooving long strips of ultra-thin floor at both ends, comprising a transmission unit and a cutting unit, wherein the transmission unit comprises a main transmission mechanism composed of an annular transmission belt assembly, and an auxiliary transmission mechanism formed by rolling support with roller groups arranged side by side at intervals, wherein the annular transmission belt assembly comprises an annular belt, a plurality of belt hooks arranged at intervals around the annular belt, and a transmission section formed by two adjacent belt hooks and corresponding annular belt parts, wherein the length of the transmission section is greater than the width of the long strips of ultra-thin floor; and the long strips of ultra-thin floor are transmitted under the joint support of the main transmission mechanism and the auxiliary transmission mechanism;

[0009] There are two cutting units, which are located at both ends and can synchronously groove both ends of the same long strip of ultra-thin floor, wherein each cutting unit includes a positioning mechanism located at the connecting end and adjusted with each belt hook passing through the connecting end as a fence, an external support mechanism arranged at the connecting end and causing the long strip of ultra-thin floor passing through to be subjected to a force along its own length and width direction to flatten the long strip of ultra-thin floor, a positioning fence mechanism located at both ends and cooperating with the external support mechanism, and a positioning fence mechanism located at the cutting section and respectively abutting against the upper and lower surfaces of the long strip of ultra-thin floor and A pressing mechanism for synchronous transmission and a cutting wheel located on the transmission path formed by the pressing mechanism are formed, wherein the long ultra-thin floor is synchronously transmitted with the annular belt after being aligned, and the external support mechanism includes a plurality of inclined transmission wheels with the same transmission direction, each inclined transmission wheel intersects with the transmission direction of the long ultra-thin floor, and forms a component force along the transmission direction of the long ultra-thin floor and along the length direction of the long ultra-thin floor toward the outer end respectively; the long ultra-thin floor transmitted to the positioning grid mechanism is aligned with the cutting wheel from the position to be grooved, and is transmitted by the pressing mechanism and cut into grooves.

[0010] Preferably, a plurality of inclined transmission wheels are aligned along the width direction of the long strip of ultra-thin floor.

[0011] In some specific embodiments, the plurality of inclined transmission wheels are distributed at equal intervals.

[0012] According to a specific implementation and preferred aspect of the present invention, the alignment mechanism is a strip brush extending along the width direction of the long strip ultra-thin floor, wherein the bristles of the strip brush brush the surface of the long strip ultra-thin floor passing by to prevent the long strip ultra-thin floor from synchronously moving with the annular belt, until the long strip ultra-thin floor is aligned against the corresponding belt hook from the side and keeps synchronous transmission. While brushing, it assists in alignment and positioning close to the belt hook.

[0013] Preferably, the bristles of each strip brush are bent in the same direction from top to bottom, and the bottom of the bristles after bending is in contact with the surface of the long strip ultra-thin floor so as to be aligned with the rear hook as the positioning reference, so as to avoid the disorder of the direction of the bristle force and the damage of the bristle.

[0014] According to another specific implementation and preferred aspect of the present invention, the positioning grid mechanism includes two grids located at both ends, wherein a receiving guide area and a transfer transmission area are formed between the two grids, and the receiving guide area is arranged near the receiving end and is in a gradually approaching trumpet shape. That is, the positioning grid mechanism includes grids located at both ends and fixedly arranged, wherein the grids are close to the receiving end to form a gradually approaching trumpet guide mouth. Further, under the interference of the grids, the long strip ultra-thin floor is prevented from shifting in its own length direction during transmission.

[0015] According to another specific implementation and preferred aspect of the present invention, the pressing mechanism includes a plurality of pressing wheel assemblies located at the upper part and an annular conveyor belt located at the lower part, wherein the pressing wheel assemblies maintain a downward movement trend and are rolled and pressed on the upper surface of the annular conveyor belt, and the cutting wheel disc is located in the middle of the plurality of pressing wheel assemblies and separates two adjacent pressing wheel assemblies, and at the same time, the cutting wheel disc is aligned with the pressing wheel assemblies and the rolling center line formed is arranged in parallel, and the long strip of ultra-thin floor is fed into the space between the pressing wheel assemblies and the annular conveyor belt to form a motion clamp, and is grooved through the cutting wheel disc in a synchronous motion. Here, by implementing the grooves in the synchronous motion clamp, and combining the limit push of the belt hook, the end of the long strip of ultra-thin floor is cut quickly and smoothly, so the cutting depth is relatively consistent, that is, the groove quality is improved.

[0016] In some specific embodiments, a plurality of pressing wheel assemblies are arranged side by side and spaced along the transmission direction of the long strip ultra-thin floor, and the plurality of pressing wheel assemblies are divided into an uncut group and a cut group according to the position of the cutting wheel disc, wherein the end of the long strip ultra-thin floor is synchronously cut in the movement connection formed by the uncut group and the cut group, so that the end of the long strip ultra-thin floor is cut synchronously during the pressing and transmission, so that the slotting and cutting are carried out during the pressing, and the cutting position is accurate and uniform.

[0017] Preferably, each pressure wheel assembly includes a fixed rod, a connecting rod rotatably connected to the lower end of the fixed rod, a pressure wheel installed on the connecting rod, and a tension spring that is synchronously stretched and restored to a natural state during the up and down movement of the pressure wheel, wherein when the long strip of ultra-thin floor contacts and lifts the pressure wheel, the tension spring is stretched to provide a downward pulling force so that the pressure wheel is pressed against the surface of the long strip of ultra-thin floor; when the pressure wheel loses contact, the pressure wheel and the tension spring are reset, and the pressure wheel is pressed on the circular conveyor belt.

[0018] Specifically, the tension spring is arranged from top to bottom and forms a first end and a second end, wherein the first end is connected to the frame shell of the cutting unit, and the second end is connected to the axle of the pressure wheel. At the same time, the first end and the second end are distributed front and back along the transmission direction of the long strip of ultra-thin floor, and the tension spring has two states. When there is no long strip of ultra-thin floor passing by, the second end is located below the first end, the tension spring is in a non-deformed state, and the pressure wheel is pressed on the circular conveyor belt by its own weight; when the long strip of ultra-thin floor passes by, the second end is located above the first end, the tension spring is stretched, and the pressure wheel maintains downward elastic pressing.

[0019] In some specific embodiments, there are two main transmission mechanisms, which are located at both ends; the auxiliary transmission mechanism is located between the two main transmission mechanisms, and the two are relatively evenly spaced. Generally, there are two auxiliary transmission mechanisms, each of which includes an auxiliary frame and auxiliary wheels installed side by side on the auxiliary frame, wherein the auxiliary frame extends along the width direction of the long strip of ultra-thin floor, and the auxiliary wheels rotate and are installed on the auxiliary frame at intervals. In this way, the long strip of ultra-thin floor can be supported and transmitted relatively flatly.

[0020] According to a specific implementation and preferred aspect of the present invention, the hooks on the upper part of the annular belt and the annular belt form a hooking direction consistent with the transmission direction of the long strip ultra-thin floor, which not only facilitates the transmission of the long strip ultra-thin floor, but also the formed leaning grid is conducive to the alignment of the long strip ultra-thin floor.

[0021] According to another specific implementation and preferred aspect of the present invention, the height of the belt hook is less than or equal to the thickness of the long strip of ultra-thin floor. Generally, the height of the belt hook is equal to the thickness of the long strip of ultra-thin floor. This avoids the belt hook from causing motion interference.

[0022] Preferably, the contact surface formed by the belt hook in the hooking direction with the long strip of ultra-thin floor is a plane, and the plane is arranged perpendicular to the corresponding annular belt, so that it is difficult to shift after abutting, which is more conducive to the end groove of the long strip of ultra-thin floor. The belt hook gradually fits the annular belt inward from the plane to the opposite direction of the transmission direction.

[0023] In addition, the receiving end includes a receiving fixing seat and a receiving mounting seat extending along the width direction of the long strip ultra-thin floor, wherein the alignment mechanism and the external support mechanism are respectively installed at both ends of the receiving mounting seat.

[0024] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0025] Based on the end grooves of the existing long and thin floors, it is difficult to maintain the grooves in a relatively flat state due to the characteristics of the floors themselves. Therefore, there is a great probability of deviation in the groove position and angle, which directly affects the assembly of the floors. At the same time, during the groove process, not only can only one end or one side be grooved at a time, but once the transmission is unstable or the cutting force formed during cutting is uneven, it will cause the grooves to slip and the grooves to have different depths. Therefore, there are shortcomings such as the groove efficiency and the groove quality cannot meet the processing needs. The present invention cleverly solves various deficiencies of the existing structure through the overall design of the synchronous cutting and grooving machine at both ends of the long and thin floors. After adopting the synchronous cutting and grooving machine at both ends of the long strip ultra-thin floor, the long strip ultra-thin floor is transmitted under the joint support of the main transmission mechanism and the auxiliary transmission mechanism. When the long strip ultra-thin floor enters the receiving end, the belt hooks passing through the receiving end are first used as the grid for alignment adjustment, and then the external support mechanism makes the long strip ultra-thin floor passing through be subjected to the force in the direction of its own length and width to flatten the long strip ultra-thin floor, and at the same time, it enters the cutting section under the restriction of the end portions of the positioning grid mechanism at both ends. At this time, the pressing mechanism that respectively contacts the upper and lower surfaces of the long strip ultra-thin floor and forms a synchronous transmission is combined with the push of the belt hook, so that the cutting wheel maintains an equal cutting amount for cutting to complete the long strip ultra-thin floor. The strip-shaped ultra-thin floor is grooved synchronously at both ends. Therefore, on the one hand, the present invention performs alignment adjustment based on the belt hook during the transmission process, flattening the end portions outwardly and limiting the end portions against the grid so that the long strip and relatively thin floor is sent into the cutting section in a relatively stable state. At the same time, in the synchronous clamping and pressing formed by the pressing mechanism, the same amount of chips is cut to complete the cutting and grooving of the ends of the long strip and relatively thin floor with high quality and high efficiency. On the other hand, the two ends of the long strip and relatively thin floor entering the cutting section are kept aligned, relatively flattened and the cutting operation is performed synchronously, that is, not only the two ends of the long strip and relatively thin floor are grooved synchronously, but also the parallelism of the grooves is high to meet the processing needs.

[0037] like Figures 1 to 4 As shown, the synchronous cutting and grooving machine for both ends of the long strip ultra-thin floor B of this embodiment includes a transmission unit 1 and a cutting unit 2, wherein there are two cutting units 2, which are located at both ends and can synchronously groove the two ends of the same long strip ultra-thin floor B.

[0038] Specifically, the transmission unit 1 includes a main transmission mechanism 10 composed of an annular transmission belt assembly 100, and an auxiliary transmission mechanism 11 formed with rolling support formed by a roller group 110 distributed side by side at intervals, wherein there are two main transmission mechanisms 10 and two auxiliary transmission mechanisms 11, and they are distributed at intervals based on the length of the long strip of ultra-thin floor B. The two main transmission mechanisms 10 are located at both ends of the length direction of the long strip of ultra-thin floor B, and the two auxiliary transmission mechanisms 11 are located between the two main transmission mechanisms 10 at intervals.

[0039] In some specific embodiments, the annular conveyor belt assembly 100 includes an annular belt a, a plurality of belt hooks b circumferentially spaced around the annular belt a, two adjacent belt hooks b and the corresponding annular belt portion form a transmission section, and the length of the transmission section is greater than the width of the long strip ultra-thin floor B; the roller assembly 110 includes an auxiliary frame f, auxiliary wheels g installed side by side on the auxiliary frame f, wherein the auxiliary frame f extends along the width direction of the long strip ultra-thin floor B, and the auxiliary wheels g rotate and are installed at intervals on the auxiliary frame f. In this way, the long strip ultra-thin floor can be supported and transmitted relatively flatly, that is, the long strip ultra-thin floor B is transmitted under the joint support of the main transmission mechanism 10 and the auxiliary transmission mechanism 11.

[0040] In this example, the hook b located on the upper part of the annular belt a forms a hooking direction with the annular belt a and is consistent with the transmission direction of the long strip ultra-thin floor B. Not only is it convenient to transmit the long strip ultra-thin floor, but the formed leaning grid is also conducive to the alignment of the long strip ultra-thin floor. At the same time, the height of the hook b is equal to the thickness of the long strip ultra-thin floor B. This can avoid the movement interference caused by the hook b. In addition, the contact surface formed by the hook b in the hooking direction with the long strip ultra-thin floor B is a plane, and the plane is perpendicular to the corresponding annular belt a. In this way, it is difficult to shift after leaning, which is more conducive to the end grooving of the long strip ultra-thin floor B. At the same time, the hook b gradually fits the annular belt a inward from the plane to the opposite direction of the transmission direction. In this example, the top surface of the hook b has an arc-shaped transition.

[0041] In this example, two cutting units 2 are symmetrically arranged at both ends. Specifically, the cutting unit 2 includes a positioning mechanism 20 located at the connecting end j and adjusted by using the belt hooks b passing through the connecting end j as a fence, an external support mechanism 21 located at the connecting end j and causing the long strip ultra-thin floor B passing through to be subjected to a force along its own length and width direction to flatten the long strip ultra-thin floor B, a positioning fence mechanism 22 located at both ends and cooperating with the external support mechanism 21, a pressing mechanism 23 located at the cutting section Q and respectively abutting against the upper and lower surfaces of the long strip ultra-thin floor B to form synchronous transmission, and a cutting wheel 24 located on the transmission path formed by the pressing mechanism 23.

[0042] In some specific embodiments, the connecting end j includes a connecting fixing seat j1 and a connecting mounting seat j2 extending along the width direction of the long ultra-thin floor B, wherein the alignment mechanism 20 and the external support mechanism 21 are respectively installed at both ends of the connecting mounting seat j2, and the connecting mounting seat j2 cross bar up and down adjustment device is arranged on the connecting fixing seat j1.

[0043] In this example, the alignment mechanism 20 is a strip brush whose length direction is consistent with the extension direction of the receiving and mounting seat j2, wherein the bristles m of the strip brush brush the surface of the long strip ultra-thin floor B passing by and align the long strip ultra-thin floor B with the corresponding belt hook b as the positioning reference. While brushing, the alignment is assisted to be positioned close to the belt hook. Furthermore, the bristles m are bent in the same direction as the transmission direction of the long strip ultra-thin floor B and are in contact with the surface of the long strip ultra-thin floor B. This avoids the disorder of the direction of the brush force and the damage of the brush. In short, the bristles m brush the surface of the long strip ultra-thin floor B passing by to prevent the long strip ultra-thin floor B from moving synchronously with the annular belt a, until the long strip ultra-thin floor B is aligned against the corresponding belt hook b from the side and maintains synchronous transmission, and the bristles m are bent in the same direction from top to bottom in an arc shape, and the bottom of the bristles after bending contacts the surface of the long strip ultra-thin floor B so that the belt hook b from the rear side is used as a positioning reference for alignment. In this example, the external support mechanism 21 includes an inclined transmission wheel 210 whose transmission direction intersects with the transmission direction of the long strip ultra-thin floor B and transmits from the inside to the outside, wherein there are at least a plurality of inclined transmission wheels 210 and they are spaced side by side along the extension direction of the receiving and mounting seat j2. Under the transmission formed by the plurality of inclined transmission wheels 210, the two ends of the long strip ultra-thin floor B are flattened outward, so that the conditions for grooving remain the same, thereby improving the quality of grooving. Here, further explanation is given, in this example, there are four inclined transmission wheels 210 (of course 3, 5, 6 or more are also possible), and the axles of each inclined transmission wheel 210 remain parallel (that is, the transmission direction is consistent), and at the same time, they are all rotatably arranged around their own axles. When the long strip of ultra-thin floor B moves, the inclined transmission wheel 210 rotates and forms a combined force direction along the length and width directions of the long strip of ultra-thin floor B to push it forward. Therefore, the relatively soft long strip of ultra-thin floor B can be relatively flattened from the end (the longer the ultra-thin floor, the more necessary it is), which plays a decisive role in the subsequent high-quality grooving.

[0044] In this example, the positioning fence mechanism 22 includes two fences 220 located at both ends, wherein the two fences 220 form a receiving guide area and a transfer transmission area, the receiving guide area is arranged near the receiving end and is in a gradually approaching trumpet shape, and the transfer transmission area is connected with the cutting section, that is, the positioning fence mechanism 22 includes fences 220 located at both ends and fixedly arranged, wherein the fences 220 form gradually approaching trumpet guides near the receiving end. Further, under the resistance of the fences 220, the long strip ultra-thin floor B is prevented from shifting in its own length direction during transmission. In this example, the pressing mechanism 23 includes a pressure wheel assembly 230 located at the upper part and an annular conveyor belt 231 located at the lower part, wherein the pressure wheel assembly 230 keeps a downward movement trend and is rolled and pressed on the upper surface of the annular conveyor belt 231, and the long strip ultra-thin floor B after receiving is sent between the pressure wheel assembly 230 and the annular conveyor belt 231 to form a moving clamp, and is slotted through the cutting wheel disc 24 in the synchronous movement. Here, the grooving is performed by synchronous motion clamping, and at the same time, the limit push of the hook is combined to quickly and smoothly cut the end of the long strip of ultra-thin flooring, so that the cutting depth is relatively consistent, that is, the grooving quality is improved.

[0045] Specifically, there are multiple pressing wheel assemblies 230, and they are spaced apart along the transmission direction of the long strip of ultra-thin floor B. The cutting wheel disc 24 is located between two pressing wheel assemblies 230 spaced apart in the middle of the multiple pressing wheel assemblies 230, so that the ends of the long strip of ultra-thin floor B can be synchronously cut during the pressing transmission, wherein the pressing transmission includes the pressing wheel assemblies 230 located on opposite sides of the cutting wheel disc 24, and the cutting amount formed by the cutting wheel disc 24 can be adjusted (specifically, it can be adjusted by moving up and down).

[0046] Further, each pressure wheel assembly 230 includes a fixed rod c, a connecting rod d rotatably connected to the lower end of the fixed rod c, a pressure wheel e installed on the connecting rod d, and a tension spring h for keeping the pressure wheel e pulled down and fitted to the annular conveyor 231, wherein the pressure wheel e is arranged to rotate around the wheel shaft; specifically, the tension spring h is arranged from top to bottom and is formed with a first end h1 and a second end h2, wherein the first end h1 is connected to the frame shell of the cutting unit 2, and the second end h2 is connected to the wheel shaft of the pressure wheel e, and at the same time, the first end h1 and the second end h2 are distributed front and back along the transmission direction of the long strip ultra-thin floor B, and the tension spring h has two states, when no long strip ultra-thin floor B passes by, the second end h2 is located below the first end h1, the tension spring h is in a non-deformed state, and the pressure wheel e is pressed on the annular conveyor 231 by its own weight; when the long strip ultra-thin floor B passes by, the second end h2 is located above the first end h1, the tension spring h is stretched, and the pressure wheel e keeps elastically pressed downward.

[0047] In summary, the implementation process of this embodiment includes the following steps:

[0048] S1, long strip ultra-thin floor B loading

[0049] Transfer the long strips of ultra-thin flooring B piece by piece to the transmission sections of the main transmission mechanism 10 and the auxiliary transmission mechanism 11 for continuous loading;

[0050] S2, Chip Grooving of Long Strip Ultra-Thin Floor B

[0051] 1) When the long strip ultra-thin floor B enters the receiving end j, the belt hooks b passing through the receiving end are first adjusted for alignment by the grid, and then the external support mechanism 21 causes the long strip ultra-thin floor B to be subjected to forces along its own length and width directions to flatten the long strip ultra-thin floor B, and at the same time, it enters the cutting section Q under the restriction of the end portions of the positioning grid mechanisms 22 at both ends;

[0052] 2) After entering the cutting section Q, the long strip of ultra-thin floor B is pressed against the upper and lower surfaces of the long strip of ultra-thin floor B to form a synchronous transmission. Combined with the push of the hook b, the cutting wheel 24 maintains an equal cutting amount for cutting, so as to complete the synchronous grooving of the two ends of the long strip of ultra-thin floor B.

[0053] In addition, if Figure 4 The state shown in the application is only for the convenience of more clear presentation of the present application scheme, but in actual operation, the cutting wheel disc 24 is located between two pressure wheel assemblies 230 spaced apart in the middle of the plurality of pressure wheel assemblies 230, so that the end of the long strip of ultra-thin floor B is cut synchronously during the pressing transmission, wherein the pressing transmission is composed of the pressure wheel assemblies 230 located on the opposite sides of the cutting wheel disc 24 and the annular conveyor belt 231 below. Here, the applicant needs to emphasize that the pressing transmission is maintained throughout the cutting process, that is, when the cutting starts, the rear pressure wheel assembly 230 provides pressing, and during the cutting process, the front pressure wheel assembly 230 provides pressing, and the pressing is maintained throughout the cutting process to avoid slipping, displacement, etc.

[0054] In summary, after adopting the synchronous cutting and grooving machine at both ends of the long strip ultra-thin floor, the long strip ultra-thin floor is transmitted under the support of the main transmission mechanism and the auxiliary transmission mechanism. When the long strip ultra-thin floor enters the receiving end, the belt hooks passing through the receiving end are first used as the grid for alignment adjustment, and then the long strip ultra-thin floor passing through is subjected to the force in the direction of its own length and width through the external support mechanism to flatten the long strip ultra-thin floor. At the same time, it enters the cutting section under the restriction of the end portions of the positioning grid mechanism at both ends. At this time, the pressing mechanism that respectively contacts the upper and lower surfaces of the long strip ultra-thin floor and forms synchronous transmission is combined with the push of the belt hook to keep the cutting wheel disc The same amount of cutting is performed to complete the synchronous grooving of the two ends of the long strip ultra-thin floor. Therefore, on the one hand, the present invention is based on the belt hook in the transmission process to adjust the position, the end is supported and leveled, and the end is limited by the grid so that the long strip and thin floor is sent to the cutting section in a relatively stable state. At the same time, in the synchronous clamping and pressing formed by the pressing mechanism, the same amount of cutting is maintained to complete the cutting and grooving of the ends of the long strip and thin floor with high quality and high efficiency; on the other hand, the two ends of the long strip ultra-thin floor entering the cutting section are kept aligned, relatively leveled, and the cutting operation is performed synchronously, that is, not only the two ends of the long strip and thin floor are synchronously The grooves are cut in one step, and the parallelism of the grooves is high to meet the processing needs; the third aspect is based on the setting of the belt hook, which is not only convenient for the transmission of the long strip ultra-thin floor, but also the formed leaning grid is conducive to the alignment of the long strip ultra-thin floor; at the same time, the height of the belt hook is equal to the thickness of the long strip ultra-thin floor, so as to avoid the movement interference caused by the belt hook. In addition, the contact surface between the belt hook and the long strip ultra-thin floor in the hooking direction is a plane, and the plane is perpendicular to the corresponding annular belt, so it is difficult to shift after abutting, which is more conducive to the end groove of the long strip ultra-thin floor; the fourth aspect is the strip brush, which assists in the alignment and positioning close to the belt hook while brushing, and the bristles are kept close to the belt hook. The long strips of ultra-thin floor are bent and pressed against the surface of the long strips of ultra-thin floor in the same direction as the transmission direction, so as to avoid confusion in the direction of the force applied by the bristles and damage to the bristles; on the fifth aspect, under the transmission formed by multiple inclined transmission wheels, the two ends of the long strips of ultra-thin floor are flattened outward, so that the conditions for grooving remain the same, thereby improving the quality of grooving, and at the same time, under the resistance of the grid, the long strips of ultra-thin floor are prevented from shifting in their own length direction during transmission; on the sixth aspect, grooving is implemented in synchronous motion clamping, and at the same time, combined with the limiting push of the hook, the ends of the long strips of ultra-thin floor are cut quickly and smoothly, so that the cutting depth is relatively consistent, that is, the grooving quality is improved.
