Description

Technical Field

[0001] This invention relates to leather processing equipment, and more particularly to a leather laser microporous machine. Background Technology

[0002] As living standards improve, artificial leather is becoming increasingly common in daily life. It is frequently seen in clothing, shoes, chairs and other household items. However, artificial leather does not have pores like animal leather, so it has poor breathability. Traditional processing methods usually involve needle punching to increase the breathability of artificial leather.

[0003] Currently, Chinese patent CN114714008A discloses a method and apparatus for laser processing of micropores in leather, including an adsorption platform, a laser drilling unit for drilling holes, a motion unit for adjusting the drilling position, an energy monitoring unit for monitoring laser energy, a processing status detection unit for monitoring the processing status, and a control unit for controlling all the above units.

[0004] However, the aforementioned patents still have shortcomings. When producing large quantities of products, the material can only be fed manually, which cannot meet the needs of large-scale processing and production. At the same time, when producing irregularly shaped raw materials such as clothing, belts, sofa leather, and other long materials that cannot be cut first, they cannot be placed on the adsorption platform as a whole, and their positions need to be adjusted manually, which affects production efficiency and increases labor costs. Summary of the Invention

[0005] In view of this, the purpose of this invention is to provide a leather laser micro-perforation machine with an automatic feeding function.

[0006] To solve the above-mentioned technical problems, the technical solution of the present invention is: a leather laser micro-perforation machine, comprising a body, with through grooves on both the front and rear sides of the body, and a feeding mechanism on the outer side of each of the two through grooves. The feeding mechanism includes a housing, a first roller, a tensioning roller, a first motor, a first power source, and a second power source. Guide grooves are provided on both sides of the housing, and through holes are provided in the guide grooves. The first roller is slidably connected to the first through hole. The first motor and the first power source are both located inside one side of the housing. The output end of the first motor is detachably connected to the end face of the first roller. The output end of the first power source abuts against the end face of the first roller. The second power source is located inside the housing on the side away from the power source, and its output end abuts against the other end face of the first roller. Leather raw material is wound around the first roller and enters the body through the tensioning roller.

[0007] Using the aforementioned technical means, leather is wound onto roller 1 for easy storage of longer pieces of leather. Rollers 1 are located on both the front and rear sides of the main body, enabling both sides to roll leather. The output end of motor 1 is detachably connected to roller 1, allowing roller 1 to be separated from motor 1 when fully wound or completely wound, facilitating roller 1 replacement. When roller 1 needs replacement, power source 1 pushes roller 1 out of through hole 1, allowing roller 1 to enter the guide groove for removal. After replacement, power source 2 pushes roller 1 into through hole 1, pressing the end face of roller 1 against the output end of motor 1, achieving automation. By tensioning the rollers, the exit position of the leather is uniform, preventing roller 1 diameter from being too large and requiring adjustment of the laser's vertical position within the main body. The rotation of motor 1 causes rollers 1 on both sides to rotate simultaneously, automatically winding the leather on one roller 1 onto the other roller 1 through the through groove, achieving automatic feeding, reducing labor costs, accelerating production efficiency, and making the leather's ventilation holes more uniform, resulting in better breathability of the produced leather.

[0008] Preferably, guide holes are provided on both sides of the housing, the tensioning roller is slidably connected to the guide holes, and a third power source is provided inside the housing, the output end of the third power source being fixedly connected to the end face of the tensioning roller.

[0009] The above-mentioned technical means can be used to adjust the position of the tension roller, thereby changing the position of the leather relative to the laser head and preventing the leather from being too thick, which would result in poor perforation.

[0010] Preferably, the feeding mechanism further includes a guiding component and a pressing component. The guiding component includes a guide block, a square tube, and a power source four. Square grooves are provided on both sides of the machine housing. The square tube is slidably connected to the square grooves. The power source four is disposed inside the machine housing. The output end of the power source four is fixedly connected to the square tube. The pressing component includes a fixing plate one, a power source five, a bending plate, a roller two, and a motor two. The fixing plate one is slidably connected to the tensioning roller. The power source five is fixedly connected to the fixing plate one. The bending plate is fixedly connected to the output end of the power source five. The roller two is rotatably connected to the bending plate. The motor two is fixedly connected to the outside of the bending plate. The output end of the motor two is fixedly connected to the roller two.

[0011] Through the aforementioned technical means, the guide block is slidably connected to the square tube, making its position adjustable to accommodate leather of wider widths. The guide block moves through the square groove to abut one side of the roller. By rotating roller one, the leather is automatically hung on the top of the guide block. At this time, the tensioning roller moves downward to below the guide block. The guide block hangs the leather on the top of the tensioning roller through the square groove. The power source five drives roller two to press the leather. After the guide block is retracted, the tensioning roller rises back, thus realizing the automatic feeding function, automating the feeding process, and saving labor costs.

[0012] Preferably, the top of the guide block has several through holes II, and a top head and a spring I are provided in the through holes II. A stepped hole is provided at the bottom of the through holes II. A stepped shaft is provided at the bottom of the top head. The stepped shaft is slidably connected to the stepped hole. A micro switch is fixedly provided at the bottom of the stepped hole. One end of the spring I abuts against the bottom of the top head, and the other end abuts against the bottom of the through holes II.

[0013] Using the above-mentioned technical means, the spring force keeps the micro switch in a normally closed state. When the top head touches the leather of the roller, the stepped shaft touches the bottom micro switch. When the roller rotates, the switch is normally open when the top head passes the leather surface. When the top head passes the leather head, the spring rebounds, causing the stepped shaft to separate from the micro switch contact. At this time, the micro switch controls the roller to rotate, causing the leather head to move along the top of the guide block. This prevents the leather head from falling off and failing to enter the top of the guide block when the leather is not rolled up tightly.

[0014] Preferably, the feeding mechanism further includes a first guide rod, a slider, a first electric push rod, and a second electric push rod. The first guide rod passes through the housing and is fixed to the housing. The slider is slidably connected to the first guide rod. The first electric push rod is mounted on the slider. The second electric push rod is fixedly connected to the housing. The output end of the second electric push rod is fixedly provided with a groove block.

[0015] Using the above-mentioned technical means, the electric push rod pushes the first roller out along the guide groove, making it easy to replace the first roller. The position of the electric push rod is controlled by the slider and the smooth rod to prevent the electric push rod from failing to push the first roller correctly due to different leather widths.

[0016] Preferably, the machine housing is fixedly provided with an upper clamping plate, and a second groove block is fixedly provided at the bottom of the upper clamping plate. The first groove block and the second groove block are used to clamp the first roller.

[0017] Using the above-mentioned technical means, when the electric push rod pushes the first roller to the top, the first roller is clamped by the first and second groove blocks, which makes it easy to replace the leather on the first roller. When the leather is replaced, there is no need to replace the first roller, which improves production efficiency and makes the replacement work more labor-saving.

[0018] Preferably, the main body further includes a pair of steel strips, and the feeding mechanism further includes a pair of material pulling components. The material pulling components include a second fixed plate, a third motor, a first clamping plate, a second clamping plate, and a second spring. The second fixed plate is fixedly connected to the housing. The third motor is mounted on the second fixed plate. The two ends of the steel strip are fixed and wound around the output ends of the two third motors. The first clamping plate has a protrusion on its top, and the protrusion is fixedly connected to the steel strip. The second clamping plate is slidably connected to the protrusion. One end of the second spring is fixedly connected to the first clamping plate, and the other end is fixedly connected to the second clamping plate. The first clamping plate is an electromagnet. When energized, the first clamping plate attracts the second clamping plate and compresses the spring.

[0019] Using the above-mentioned technical means, the leather on the tensioning roller is fed between clamping plate one and clamping plate two. By energizing clamping plate one, it becomes magnetic, thereby attracting clamping plate two to clamp the leather. The rotation of motor three drives the protrusions on the steel belt to move, so that the leather passes through the inside of the body into the through groove at the other end, replacing manual labor and improving the degree of automation.

[0020] Preferably, the feeding mechanism further includes a second light rod and a fixed base. The second light rod passes through the second fixed plate and is fixedly connected to the second fixed plate. The fixed base is slidably connected to the second light rod. A locking hole is provided on the top of the fixed base. The third motor is fixedly connected to the fixed base.

[0021] Through the aforementioned technical means, the fixing base and the light rod are slidably connected, making it suitable for leathers of more widths. By screwing a screw into the keyhole, the light rod is compressed by the screw, allowing the fixing base to be fixed at any position on the light rod. Attached Figure Description

[0033] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, so that the technical solution of the present invention can be more easily understood and mastered.

[0034] A leather laser microporous machine, such as Figure 1 , Figure 2 , Figure 3As shown, the device includes a main body 1. Both the front and rear sides of the main body 1 have through slots 101, allowing leather to pass through. A feeding mechanism 2 is provided on the outer side of each through slot 101. The leather slides from one feeding mechanism 2 to the other, achieving automatic feeding. The feeding mechanism 2 includes a housing 3, a first roller 4, a tension roller 5, a first motor 6, a first power source 7, and a second power source 8. The first and second power sources 7 and 8 include cylinders. Guide slots 301 are provided on both sides of the housing 3, allowing the sides of the first roller 4 to slide along the guide slots 301. A through hole 302 is provided in the guide groove 301. The roller 4 slides along the through hole 302. The motor 6 and the power source 7 are both located inside one side of the housing 3 to prevent dust accumulation. The output end of the motor 6 is detachably connected to the end face of the roller 4. The output end of the power source 7 abuts against the end face of the roller 4. The power source 8 is located inside the housing 3 away from the power source 7, and its output end abuts against the other end face of the roller 4. When the roller 4 needs to be replaced, the output end of the power source 8 retracts, and the power source 7 pushes the roller 4 out of the through hole 302.

[0035] like Figure 3 , Figure 7 As shown, guide holes 303 are provided on both sides of the housing 3. The tensioning roller 5 is slidably connected to the guide holes 303. A power source 9 is also provided inside the housing 3. The output end of the power source 9 is fixedly connected to the end face of the tensioning roller 5 to control the tensioning roller to move along the guide holes 303.

[0036] like Figure 3 , Figure 5 , Figure 6 As shown, the feeding mechanism 2 also includes a guide assembly 10 and a pressing assembly 15. The guide assembly 10 includes a guide block 11, a square tube 12, and a power source 4 13. Square grooves 304 are provided on both sides of the housing 3. The square tube 12 is slidably connected to the square grooves 304. The power source 4 13 is located inside the housing 3. The output end of the power source 4 13 is fixedly connected to the square tube 12 to control the square tube 12 to move along the square grooves 304. The guide block 11 moves through the square grooves 304 to abut against the side of the roller 4. By rotating the roller 4, the leather is automatically hung on the top of the guide block 11.

[0037] The pressing assembly 15 includes a fixed plate 16, a power source 17, a bending plate 18, a roller 19, and a motor 20. The fixed plate 16 is slidably connected to the tensioning roller 5 to make it suitable for leather of more sizes. The power source 17 is fixedly connected to the fixed plate 16 to control the up and down movement of the roller 19. The power source 17 includes a cylinder. The bending plate 18 is fixedly connected to the output end of the power source 17. The roller 19 is rotatably connected to the bending plate 18. The motor 20 is fixedly connected to the outside of the bending plate 18. The output end of the motor 20 is fixedly connected to the roller 19. When the leather is hooked onto the top of the guide block 11, the tensioning roller 5 moves downward to below the guide block 11 via the power source 39. The guide block 11 hooks the leather onto the top of the tensioning roller 5 via the square groove 304. The power source 17 drives the roller 19 to press the leather. After the guide block 11 is retracted, the tensioning roller 5 rises back.

[0038] like Figure 6 , Figure 8 , Figure 9 As shown, the top of the guide block 11 has several through holes 111. Inside each through hole 111, there is a top head 112 and a spring 113. At the bottom of the through hole 111, there is a stepped hole 114. At the bottom of the top head 112, there is a stepped shaft 115. The stepped shaft 115 is slidably connected to the stepped hole 114. At the bottom of the stepped hole 114, there is a micro switch 116. One end of the spring 113 abuts against the bottom of the top head 112, and the other end abuts against the bottom of the through hole 111. The spring force keeps the micro switch 116 in a normally closed state. When the top head 112 abuts against the leather of the roller 4, the stepped shaft 115 abuts against the bottom micro switch 116. When the roller rotates, the switch is normally open when the top head 112 passes through the leather surface. When the top head 112 passes through the leather head, the spring rebounds, causing the step shaft 115 to separate from the micro switch 116. At this time, the micro switch 116 controls the roller to rotate in the opposite direction, causing the leather head to move along the top of the guide block 11.

[0039] like Figure 2 , Figure 4 As shown, the feeding mechanism 2 also includes a light rod 21, a slider 22, an electric push rod 23, and an electric push rod 24. The light rod 21 passes through the housing 3 and is fixed to the housing 3. The slider 22 is slidably connected to the light rod 21. The electric push rod 23 is set on the slider 22. The electric push rod 24 is fixedly connected to the housing 3. The output end of the electric push rod 24 is fixedly provided with a groove block 25. The electric push rod pushes the roller 4 out along the guide groove 301, replacing the manual removal of the push rod. This makes it easier to replace the roller 4. The position of the electric push rod 23 is controlled by the slider 22 and the light rod 21 to prevent the electric push rod 23 from failing to push the roller 4 correctly due to different leather widths.

[0040] The housing 3 is fixedly provided with an upper clamping plate 26, and a second groove block 27 is fixedly provided at the bottom of the upper clamping plate 26. The first groove block 25 and the second groove block 27 are used to clamp the first roller 4. Usually, there is a layer of paper core rod between the first roller 4 and the leather. The leather is usually wrapped around the paper core rod to prevent excessive friction between the leather and the first roller 4, which would make it impossible to remove. By clamping the first roller 4 with the first groove block 25 and the second groove block 27, the paper core rod can be directly detached from the first roller 4, so that the first roller 4 does not need to be removed together when the leather is replaced.

[0041] like Figure 10 As shown, the main body 1 also includes a pair of steel strips 28, and the feeding mechanism 2 also includes a pair of material pulling components 29. The material pulling components 29 include a second fixing plate 30, a third motor 31, a first clamping plate 32, a second clamping plate 33, and a second spring 34. The second fixing plate 30 is fixedly connected to the housing 3. The third motor 31 is mounted on the second fixing plate 30. The two ends of the steel strips 28 are fixed and wound around the output ends of the two third motors 31. The top of the first clamping plate 32 is provided with a protrusion 321, which is fixedly connected to the steel strips 28. Clamping plate 33 is slidably connected to protrusion 321. One end of spring 34 is fixedly connected to clamping plate 32, and the other end is fixedly connected to clamping plate 33. Clamping plate 32 is an electromagnet. The leather on the tensioning roller 5 is fed between clamping plate 32 and clamping plate 33. By energizing clamping plate 32, it becomes magnetic, thereby attracting clamping plate 33 to clamp the leather. The rotation of motor 31 drives the protrusion 321 on steel belt 28 to move, thereby allowing the leather to pass through the interior of body 1 to the other end.

[0042] The feeding mechanism 2 also includes a second smooth rod 35 and a fixed seat 36. The second smooth rod 35 passes through the second fixed plate 30 and is fixedly connected to the second fixed plate 30. The fixed seat 36 is slidably connected to the second smooth rod 35. The top of the fixed seat 36 is provided with a locking hole 361, which can be fixed by screws.

[0043] Of course, the above are just typical examples of the present invention. In addition, the present invention may have many other specific embodiments. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by the present invention.
