[0002] Leather is the animal skin that has been denatured and is not easily perishable through physical and chemical processes such as hair removal and tanning. During the evolution of mankind, it was found that the juices of some plants or mineral oils have a certain tanning property for leather. Through the soaking of raw hides in the juices, the leather becomes more breathable and preservable. As a result, the leather has physical and chemical properties such as softness, tear resistance, and flex resistance. Only at this time does the leather truly possess the characteristics of leather products. And this kind of juice is called tanning agent. In leather production, it is necessary to cut leather.

[0017] As Figures 1 to 3 shown, an embodiment of the present invention provides a leather cutting device for leather production. The leather cutting device for leather production includes a feeding mechanism 10 and a cutting mechanism 20. The feeding mechanism 10 includes a first linear driving component 11 arranged along the first direction X, a rotary driving component 13 connected to the output end of the first linear driving component 11, and a workbench 12 arranged at the output end of the rotary driving component 13. The first linear driving component 11 is configured to drive the rotary driving component 13 and the workbench 12 as a whole to reciprocate along the first direction X. The rotary driving component 13 is configured to drive the workbench 12 to rotate linearly around the first rotating shaft 112 perpendicular to the tabletop. The cutting mechanism 20 includes a second linear driving component 21 arranged along the second direction Y, a lifting component 22 connected to the output end of the second linear driving component 21, and a cutting component 23 arranged at the output end of the lifting component 22. The second linear driving component 21 is configured to drive the lifting component 22 and the cutting component 23 as a whole to reciprocate along the second direction Y. The lifting component 22 is configured to drive the cutting component 23 to lift along the third direction Z. Among them, the third direction Z is the direction perpendicular to the tabletop of the workbench 12. The first direction X, the second direction Y, and the third direction Z intersect pairwise to form a three-dimensional space. The workbench 12 and the cutting component 23 form a relative movement with multiple degrees of freedom in the three-dimensional space.

[0018] The leather cutting equipment for leather goods production in this embodiment uses the first linear drive assembly 11 to drive the rotation assembly and the workbench 12 as a whole to move along the first direction X, so that the workbench 12 moves to the position for receiving leather. After placing the leather on the workbench 12, the first linear drive assembly 11 drives the rotation assembly and the workbench 12 as a whole to approach the cutting assembly 23. Until it moves to the cutting position, the second linear drive assembly 21 is used to drive the cutting assembly 23 to move along the second direction Y, so that the cutting assembly 23 is located on one side of the workbench 12, and at the same time, the lifting assembly 22 is used to drive the cutting assembly 23 to move along the third direction Z. Until the cutting position of the cutting assembly 23 is adjusted, the lifting assembly 22 stops adjusting the lifting of the cutting assembly 23. In addition, the cutting assembly 23 is located outside the workbench 12. Then, the second linear drive assembly 21 is used to drive the cutting assembly 23 to move from one side of the workbench 12 to the other side, so as to realize automatic cutting of the leather on the workbench 12, without manual cutting, which is beneficial to reducing labor intensity, improving cutting efficiency, and at the same time preventing potential safety hazards of operators from being injured during the cutting process.

[0019] In a possible implementation manner, the first linear drive assembly 11 includes a first base 111, a first rotating shaft 112, a first slider 113, and a first driving member 114. The first base 111 is arranged below the second linear drive along the first direction X, and the first base 111 has a first accommodation space opened along the first direction X; the first rotating shaft 112 is rotatably arranged in the first accommodation space, and one end penetrates through the first base 111 and extends outside the first accommodation space; the first slider 113 is slidably arranged on the first rotating shaft 112 and is connected to the rotation drive assembly 13; the first driving member 114 is installed at one end of the first base 111 in the first direction X and is connected to the end of the first rotating shaft 112 extending outside the first accommodation space. The first driving member 114 is configured to drive the first rotating shaft 112 to rotate, so as to drive the first slider 113 to reciprocate on the first rotating shaft 112.

[0020] Exemplarily, the first driving member 114 is used to drive the first rotating shaft 112 to rotate, so as to drive the first slider 113 to slide on the first rotating shaft 112, and then drive the workbench 12 to move along the first direction X until the workbench 12 moves to the position for receiving leather. Then, the first driving member 114 is used to drive the first rotating shaft 112 to reverse, so as to drive the workbench 12 to move along the first direction X towards the direction close to the cutting assembly 23 until the workbench 12 moves to the position where it can be cut by the cutting assembly 23, thus realizing automatic reception of leather and sending it to the cutting position, without manual operation, which is beneficial to reducing labor intensity.

[0021] In a possible implementation, the rotary drive assembly 13 includes a support plate 131 and a rotary power member 132. The support plate 131 is disposed above the first base 111 and is connected to the first slider 113. The rotary power member 132 is installed on the surface of the support plate 131 facing away from the first base 111. A connection block 133 is connected to the output end of the rotary power member 132, and the connection block 133 is connected to the back surface of the workbench 12. In this way, the rotary power member 132 can be used to drive the connection block 133 to rotate. Since the connection block 133 is connected to the back surface of the workbench 12, the workbench 12 can be driven to rotate, so that the cutting position of the leather can be adjusted according to the cutting requirements.

[0022] In a possible implementation, the workbench 12 includes a box body 121. An independent space is defined inside the box body 121. An opening 121b for changing the negative pressure of the independent space is formed in the box body 121. A plurality of adsorption holes 121a communicating with the independent space are distributed on the top of the box body 121. The adsorption holes 121a are used to adsorb the leather placed in the box body 121. In this way, the negative pressure in the independent space can be adjusted by an external negative pressure device. Since a plurality of adsorption holes 121a communicating with the independent space are distributed on the top of the box body 121, the leather placed on the workbench 12 can be adsorbed, preventing the leather from moving during the cutting process, which may lead to inaccurate cutting or even the problem that cutting cannot be achieved.

[0023] In a possible implementation, the second linear drive assembly 21 includes a frame 24, a second base 211, a second rotating shaft 212, a second slider 213, and a second driving member 214. The second base 211 is disposed on the frame 24 along the second direction Y. The second base 211 has a second accommodation space opened along the second direction Y. The second rotating shaft 212 is rotatably disposed in the second accommodation space, and one end thereof penetrates through the second base 211 and extends out of the second accommodation space. The second slider 213 is slidably disposed on the second rotating shaft 212 and is connected to the lifting assembly 22. The second driving member 214 is installed at one end of the second base 211 in the second direction Y and is connected to the end of the second rotating shaft 212 extending out of the second accommodation space. The second driving member 214 is configured to drive the second rotating shaft 212 to rotate, so as to drive the second slider 213 to reciprocate on the second rotating shaft 212.

[0024] Exemplarily, when it is necessary to cut the leather placed on the workbench 12, first use the second driving member 214 to drive the second rotating shaft 212 to rotate, so as to drive the second slider 213 to slide on the second rotating shaft 212, and then drive the lifting assembly 22 to move along the second direction Y, so as to adjust the cutting assembly 23 to one side of the workbench 12. At the same time, the lifting assembly 22 adjusts the cutting assembly 23 along the third direction Z until the cutting assembly 23 is adjusted to the cutting position. After that, the second driving assembly drives the second rotating shaft 212 to reverse, so as to drive the lifting assembly 22 to move along the second direction Y, and then drive the cutting assembly 23 to move from one side of the workbench 12 to the other side, thus realizing the automatic cutting of the leather, without manual cutting, which is beneficial to reducing the labor intensity of workers and avoiding potential safety hazards caused by improper operation.

[0025] It should be noted that the second driving member 214 in this embodiment can be a driving motor or other power components in the prior art, and there is no limitation in this regard.

[0026] In a possible implementation manner, the lifting assembly 22 includes a moving plate 221 and a lifting power member 222. The moving plate 221 is connected to the second sliding plate; the lifting power member 222 is installed on the surface of the moving plate 221 facing away from the frame 24, and the output shaft of the lifting power member 222 is connected to the cutting assembly 23, and is used to drive the cutting assembly 23 to lift along the third direction Z. In practical applications, after placing the leather to be cut on the workbench 12, it is necessary to adjust the cutting assembly 23 to the cutting position, and then use the second linear driving assembly 21 to drive the cutting assembly 23 to move along the second direction Y, so that the cutting assembly 23 moves from one side of the workbench 12 to the other side, thus realizing the cutting of the leather. That is to say, the lifting power member 222 is used to adjust the position of the cutting assembly 23 in the third direction Z and plays a role in adjusting the position of the cutting assembly 23. Among them, the lifting power member 222 includes but is not limited to a lifting cylinder, an electric telescopic rod, etc.

[0027] In a possible implementation, the cutting assembly 23 includes a mounting base 231, a rotary driving member 232, and a cutting tool 233. The mounting base 231 is connected to the conveying end of the lifting driving member; the rotary driving member 232 is mounted on the mounting base 231, and the output end of the rotary driving member 232 faces the tabletop of the workbench 12 in the third direction Z; the cutting tool 233 is mounted on the output end of the driving power member and is used for cutting the leather placed on the workbench 12. That is to say, when the cutting assembly 23 is adjusted to the cutting position, the rotary driving member 232 drives the cutting tool 233 to rotate, and cooperates with the second driving member 214 to drive the second rotating shaft 212 to rotate, so that the second slider 213 slides on the second rotating shaft 212, and then drives the moving plate 221 to move along the second direction Y from one side of the workbench 12 to the other side, thereby driving the cutting tool 233 to cut the leather placed on the workbench 12. Here, it should be noted that the "cutting position" mentioned above refers to the position where the cutting tool 233 is outside the workbench 12 and can contact the leather on the workbench 12. In addition, the rotary power member 132 can be a rotary motor or a power member that can drive the cutting tool 233 to rotate, and this is not limited herein.

[0028] In a possible implementation, the frame 24 includes a cross beam 241 arranged along the first direction X and two vertical beams 242 arranged along the second direction Y. One ends of the two vertical beams 242 close to the cross beam 241 are connected to both ends of the cross beam 241, and the second base 211 is fixed on the cross beam 241. Exemplarily, the two vertical beams 242 are connected to both ends of the cross beam 241 so that the cross beam 241 is erected above the workbench 12. Since the second base 211 is mounted on the cross beam 241 and the cutting assembly 23 is connected to the second slider 213, the cutting assembly 23 can move back and forth along the second direction Y above the workbench 12, and thus can realize cutting the leather placed on the workbench 12. That is to say, the frame 24 functions to fix the second base 211 so that the cutting assembly 23 is suspended above the workbench 12, and at the same time can also prevent the second base 211 from moving randomly during the sliding process of the second slider 213, resulting in deviation of the movement of the cutting assembly 23 and thus affecting the cutting accuracy. In addition, in actual applications, both the cross beam 241 and the vertical beams 242 are made of metal materials to ensure that the formed frame 24 has strong structural strength and is not easily deformed.

[0029] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and substitutions can be made, and these improvements and substitutions should also be regarded as the protection scope of the present invention.
