[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making any creative work shall fall within the scope of protection of the present application.

[0025] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods.

[0026] Example

[0027] like Figure 1-Figure 7 As shown, a leather flattening and cutting device includes: a cutting table 1, a groove 101 opened on the top of the cutting table 1, a fixing frame 102 installed on the top of the cutting table 1, a cutting knife 103 arranged at the bottom of the fixing frame 102, flattening components arranged on both sides of the bottom of the fixing frame 102, used for flattening the leather on the cutting table 1, and a cleaning component arranged at the outer end of the groove 101, used for cleaning debris generated by cutting the groove 101.

[0028] Among them, the flattening component includes: an equipment box a2 installed on both sides of the top of the fixed frame 102, forward and reverse motors a201 are installed on the outer ends of the equipment box a2, a screw rod a202 installed inside the equipment box a2 and connected to the forward and reverse motors a201, the surface of the screw rod a202 is provided with two threads in opposite directions, and the threads are connected to two wire sleeves a203 in a "T" shape on the screw rod a202, and the bottom of the two wire sleeves a203 are installed with fixed plates a204, and lifting cylinders a205 are installed on both sides of the top of the fixing plate a204, and a telescopic rod a206 is connected to the bottom of the lifting cylinder a205. A through groove a for the movement of the lifting cylinder a205 and the two wire sleeves a203 is opened at the bottom of the equipment box a2, and a pressure plate 207 is installed at the bottom of the telescopic rod a206.

[0029] When cutting leather, the leather is placed on the cutting table 1, that is, the pressure plates 207 on both sides of the bottom of the equipment box a2 face the leather, and the lifting cylinder a205 is started to push the telescopic rod a206 to move downward. The telescopic rod a206 drives the pressure plate 207 to move downward and contact the leather, and cooperates with the cutting table 1 to press the leather and place it tightly, so that the leather is in a taut state to avoid loosening during cutting. When pressing leather with a large width, the forward and reverse motors a201 are started to drive the screw rod a202 to rotate forward. Since the screw rod a202 is provided with two wire sleeves a203 and two threads in opposite directions, the two wire sleeves a203 and the threads on the screw rod a202 rotate, causing the two wire sleeves a203 to move forward. The two threads on the screw rod a202 of the two silk sleeves a203 rotate, so that the two silk sleeves a203 move closer in the same direction, that is, the pressing plates 207 at the bottom of the two silk sleeves a203 move closer, so that the leather with a small width can be flattened and placed. The width distance between the pressing plates 207 can be flexibly adjusted, which is convenient for flattening and placing leather of different widths.

[0030] Among them, an equipment box b3 is installed on the top of the fixed frame 102, and a forward and reverse motor b301 is installed on the outer end of the equipment box b3. A screw rod b302 connected to the forward and reverse motor b301 is installed inside the equipment box b3, and the surface of the screw rod b302 is provided with a thread, and a wire sleeve b303 with a "T"-shaped structure is threaded on the screw rod b302. A fixed plate b304 is installed at the bottom of the wire sleeve b303, and lifting cylinders b305 are installed on both sides of the top of the fixed plate b304. The bottom of the lifting cylinder b305 is connected to a telescopic rod b306, and the bottom of the telescopic rod b306 is connected to the cutting knife 103. A through slot b for the movement of the lifting cylinder b305 and the wire sleeve b303 is provided at the bottom of the equipment box b3.

[0031] After the leather is flattened and placed on the cutting table 1, the lifting cylinder b305 is started to push the telescopic rod b306 downward, and the telescopic rod b306 pushes the cutting knife 103 to move downward and contact the leather to cut it. At the same time, the forward and reverse motor b301 is started to drive the screw rod b302 to rotate forward, and the silk sleeve b303 rotates on the screw rod b302, driving the silk sleeve b303 to move its position on the screw rod b302, that is, the silk sleeve b303 drives the fixed plate b304, the lifting cylinder b305, the telescopic rod b306 and the cutting knife 103 to move backward, so that the cutting knife 103 cuts the leather. After the leather is cut, the lifting cylinder b305 drives the telescopic rod b306 to move upward, and the telescopic rod b306 drives the cutting knife 103 to move upward and away from the leather, and controls the pressing plate 207 to be lifted, so that the cut leather can be taken away.

[0032] The groove 101 is directly opposite to the cutting knife 103, and the width of the groove 101 is larger than the width of the cutting knife 103. When the cutting knife 103 is cutting leather, the setting of the groove 101 can prevent the cutting knife 103 from directly cutting the cutting table 1, and can provide anti-touch protection for the cutting knife 103. In addition, the width of the groove 101 is larger than the width of the cutting knife 103, so that the cutting knife 103 has a large enough space to move inside the groove 101 for cutting.

[0033] Among them, a concave mounting frame 307 is fixed to the bottom of the telescopic rod b306 by bolts, and sockets 308 are provided on both sides of the outer end of the concave mounting frame 307 and the outer side of the top of the cutting knife 103. A fixing screw 309 is provided inside the socket 308, and a fixing nut 310 is threadedly connected to one end of the fixing screw 309.

[0034] When using the cutting knife 103, the top of the cutting knife 103 is inserted into the concave mounting frame 307, and it fits tightly with the inner walls of the concave mounting frame 307. At this time, the socket 308 on the outside of the top of the cutting knife 103 is aligned with the sockets 308 on both sides of the outer end of the concave mounting frame 307, and the fixing screw 309 is inserted into the socket 308. Then, the fixing nut 310 is screwed into one end of the fixing screw 309 until the fixing nut 310 is tightened and fits tightly with the outer side of the concave mounting frame 307, and then the cutting knife 103 is installed at the bottom of the concave mounting frame 307 for use.

[0035] When the cutting knife 103 is not sharp or the blade is damaged, the fixing nut 310 is loosened and removed from the fixing screw 309, and the fixing screw 309 is pulled out from the inside of the socket 308, so that the damaged cutting knife 103 can be replaced.

[0036] Among them, the cleaning component includes: a box body 4 installed on the back of the cutting table 1, a discharge pipe 401 installed on the top of the box body 4, a debris suction pipe 402 installed on the top of the discharge pipe 401, and one end of the debris suction pipe 402 is connected to the groove 101, a suction fan 403 installed at the other end of the debris suction pipe 402, an exhaust pipe installed at the outer end of the suction fan 403, and a collection box 404 arranged inside the box body 4.

[0037] The debris generated when the cutting knife 103 cuts the leather will fall into the groove 101. During the cutting process, the suction fan 403 can be started to work, and the suction fan 403 generates negative pressure suction on the inside of the suction pipe 402, and the gas is discharged from the exhaust pipe. Since one end of the suction pipe 402 is connected to the groove 101, that is, the suction pipe 402 is connected to the groove 101, the suction pipe 402 can suck the debris inside the groove 101 and suck it into the inside of the suction pipe 402. When passing through the discharge pipe 401, the debris inside the suction pipe 402 will fall into the discharge pipe 401 and then be discharged from the discharge pipe 401 to the collection box 404 for collection and storage of the debris, which is convenient for cleaning the debris. The debris inside the groove 101 is cleaned during cutting, avoiding the hand being cut by accidentally touching the cutting knife 103 during manual cleaning, and also avoiding the accumulation of debris inside the groove 101 causing blockage.

[0038] Among them, a control box is fixedly installed on one side of the outer end of the cutting table 1, a plurality of control buttons are installed on the top of the control box, and a power cord is installed on the back of the control box. The forward and reverse motor a201, the lifting cylinder a205, the forward and reverse motor b301, the lifting cylinder b305 and the suction fan 403 are connected to the control box through wires, and the wires are reserved with sufficient length to ensure that they will not be pulled apart during the back and forth pulling process. The power cord is two meters long, and a plug is installed at the other end of the power cord, which can be inserted into the indoor socket to turn on the power, so that The control chassis, forward and reverse motor a201, lifting cylinder a205, forward and reverse motor b301, lifting cylinder b305 and suction fan 403 are powered on and used normally. The control chassis can control the start and stop of forward and reverse motor a201, lifting cylinder a205, forward and reverse motor b301, lifting cylinder b305 and suction fan 403. The control procedures involved in the present invention can be implemented by technical personnel in this field according to the same or similar principles in the prior art. This part is not the innovation of the present invention.

[0039] Among them, a mesh partition 405 is installed inside the suction pipe 402, and the mesh partition 405 is set flush with the top side of the discharge pipe 401. When the suction pipe 402 sucks in debris and impurities, the mesh partition 405 uses a 600-mesh fine mesh, which can block the debris and impurities from falling into the discharge pipe 401, avoiding being sucked into the suction fan 403 and causing damage.

[0040] Working principle:

[0041] When cutting leather, the leather is placed on the cutting table 1, that is, the pressure plates 207 on both sides of the bottom of the equipment box a2 face the leather, and the lifting cylinder a205 is started to push the telescopic rod a206 to move downward. The telescopic rod a206 drives the pressure plate 207 to move downward and contact the leather, and cooperates with the cutting table 1 to press the leather and place it tightly, so that the leather is in a taut state to avoid loosening during cutting. When pressing leather with a large width, the forward and reverse motors a201 are started to drive the screw rod a202 to rotate forward. Since the screw rod a202 is provided with two wire sleeves a203 and two threads in opposite directions, the two wire sleeves a203 and the threads on the screw rod a202 rotate, causing the two wire sleeves a203 to move forward. The two threads on the screw rod a202 of the two silk sleeves a203 rotate, so that the two silk sleeves a203 move closer in the same direction, that is, the pressing plates 207 at the bottom of the two silk sleeves a203 move closer, so that the leather with a small width can be flattened and placed. The width distance between the pressing plates 207 can be flexibly adjusted, which is convenient for flattening and placing leather of different widths.

[0042] After the leather is flattened and placed on the cutting table 1, the lifting cylinder b305 is started to push the telescopic rod b306 downward, and the telescopic rod b306 pushes the cutting knife 103 to move downward and contact the leather to cut it. At the same time, the forward and reverse motor b301 is started to drive the screw rod b302 to rotate forward, and the silk sleeve b303 rotates on the screw rod b302, driving the silk sleeve b303 to move its position on the screw rod b302, that is, the silk sleeve b303 drives the fixed plate b304, the lifting cylinder b305, the telescopic rod b306 and the cutting knife 103 to move backward, so that the cutting knife 103 cuts the leather. After the leather is cut, the lifting cylinder b305 drives the telescopic rod b306 to move upward, and the telescopic rod b306 drives the cutting knife 103 to move upward and away from the leather, and controls the pressing plate 207 to be lifted, so that the cut leather can be taken away.

[0043] During the cutting process, the suction fan 403 can be started to generate negative pressure suction on the inside of the suction pipe 402, and the gas is discharged from the exhaust pipe. Since one end of the suction pipe 402 is connected to the groove 101, that is, the suction pipe 402 is connected to the groove 101, the suction pipe 402 can suck away the debris inside the groove 101 and suck it into the inside of the suction pipe 402. When passing through the discharge pipe 401, the debris inside the suction pipe 402 will fall into the discharge pipe 401, and then be discharged from the discharge pipe 401 to the collection box 404 for collection and storage of the debris, which is convenient for cleaning the debris. The debris inside the groove 101 is cleaned during cutting to avoid accidentally touching the cutting knife 103 during manual cleaning and causing cuts to the hands, and to avoid debris accumulation inside the groove 101 and causing blockage.
