CNC cutting device for bed board leather

Abstract

This invention provides a CNC cutting device for leather bed boards, including a machine tool. A base plate is provided on the upper surface of the machine tool. A moving mechanism is installed at the edge of the upper surface of the machine tool. A driving mechanism is installed on the outer side of the moving mechanism. A cutting head is installed at the bottom of the driving mechanism. A transmission component for pressing and fixing is installed on one side of the driving mechanism. When the separating main plate and separating secondary plate move downward and adhere to the leather material, they are subjected to force to compress the second return spring on one side. The bottom separating main plate and separating secondary plate are located at the same horizontal line as the bottom ends of the adjacent separating main plates and separating secondary plates. As the moving mechanism drives the driving mechanism to move, the bottom separating main plate and separating secondary plate press and fix the leather material. The adjacent separating main plates and separating secondary plates continuously roll alternately to press and fix the leather material, thereby preventing the leather material from loosening and shifting during the cutting process of the cutting head, which would cause cutting errors.

Description

Technical Field

[0001] This invention relates to the field of general mechanical processing or processing technology of leather, and more particularly to a CNC cutting device for bed board leather. Background Technology

[0002] Massage beds are usually covered with leather to provide comfort. During the process of covering the bed board, the leather needs to be cut to the corresponding size. Cutting the leather mainly involves cutting according to the set leather cutting values ​​to improve cutting efficiency, which in turn facilitates the packaging of the massage bed and improves comfort. This provides technical inspiration for cutting the leather material of the bed board.

[0003] The study on the cutting of leather bed boards revealed the following problems:

[0004] When the bed board leather cutting device cuts leather, it uses a cutting blade to cut the leather. However, during the long cutting process, the blade tip is prone to dulling. This dulling of the blade tip after prolonged cutting results in incomplete cuts by subsequent cuts, leaving connecting threads. This reduces the cutting efficiency of the bed board leather cutting device, thereby reducing the production efficiency of massage bed packaging and failing to achieve the goal of improving cutting efficiency.

[0005] Currently, the existing technology CN116814869A discloses an anti-deviation cutting device for leather production, which includes a bed board leather cutting device. This invention uses a limiting device to limit and cut the leather to be cut, so that the leather will not deviate during cutting, thus maintaining the dimensional stability of the cut leather. By setting a winding device, the leather to be cut can be wound up and moved on the surface of the U-shaped panel, thereby cutting the leather and winding up the cut leather. The setting of a servo motor can make the second rotating rod rotate, thereby enabling the winding device to wind up the leather.

[0006] This invention primarily addresses the problem that after prolonged cutting of leather, the blade leaves connecting threads, preventing the leather cutting device from achieving its cutting efficiency. Summary of the Invention

[0007] To solve the above-mentioned technical problems, the present invention provides a CNC cutting device for bed board leather to solve the problems described in the background art.

[0008] The purpose and effectiveness of the CNC cutting device for bed board leather of the present invention are achieved by the following specific technical means: The CNC cutting device for bed board leather includes a machine tool, a base plate is provided on the upper surface of the machine tool, a moving mechanism is installed at the edge of the upper surface of the machine tool, a driving mechanism is installed on the outer side of the moving mechanism, a cutting head is installed at the bottom of the driving mechanism, and a transmission component for pressing and fixing is installed on one side of the driving mechanism. The transmission component includes a separation main plate, a separation sub-plate, a central column, a central plate, a sliding plate, a second return spring, a transmission column, and a lead screw. A central plate is provided on one side of the separation main plate, a separation sub-plate is provided on the side of the central plate away from the separation main plate, a second return spring is connected to one side of the separation sub-plate, a sliding plate is connected to the end of the second return spring away from the separation sub-plate, a central column is provided on the outer side of the sliding plate, a transmission column is provided on one side of the central column, and a lead screw is installed on the side of the transmission column away from the central column.

[0009] Furthermore, the central column is pentagonal in shape, and each of its five faces has a groove that matches the sliding plate.

[0010] Furthermore, the ten slide plates are symmetrically arranged on the outer side of the central column, and one side of each of the ten slide plates is connected to the separation main plate and the separation sub-plate respectively through a second reset spring.

[0011] Furthermore, the five separate main boards are arranged in a ring around the outer side of the central column. The five separate main boards are not attached to each other, and each of the separate main boards has a slot that matches the central board on the side closest to the separate sub-board.

[0012] Furthermore, each of the five separate sub-plates has a slot matching the central plate on the side closest to the five separate main plates, and a reset component for tearing is provided on the side of the separate sub-plates away from the separate main plates. The five separate sub-plates and the five separate main plates are mirror images of each other at the center of the central plate.

[0013] Furthermore, the reset assembly includes a connecting mechanism, a connecting plate, a push rod, a connecting rod, a first reset spring, a rotating shaft, and a torsion spring. The connecting plate is installed at the bottom of the connecting mechanism, and a torsion spring is provided on one side of the connecting plate. One end of the torsion spring is connected to the rotating shaft, and the end of the rotating shaft away from the torsion spring is connected to the first reset spring. The end of the first reset spring away from the rotating shaft is connected to the push rod, and the outer side of the push rod is connected to the connecting rod.

[0014] Furthermore, a through hole is provided on one side of the connecting plate, and a torsion spring is installed inside the through hole.

[0015] Furthermore, the end of the push rod away from the first reset spring has a threaded hole that matches the lead screw, and the diameter of the push rod is equal to the diameter of the through hole on one side of the connecting plate.

[0016] Furthermore, the connecting rods are arranged in a ring around the outer side of the push rod, and there are five connecting rods. The end of each of the five connecting rods away from the outer side of the push rod is connected to one side of the separation sub-plate.

[0017] Furthermore, the two push rods, the first reset spring, the rotating shaft, the torsion spring, and the ten connecting rods are symmetrically arranged around the center plate, with five of the connecting rods connected to the side of the five separation main plates away from the separation sub-plate.

[0018] Beneficial effects:

[0019] 1. When the main separating plate and the secondary separating plate move downwards to adhere to the leather material, they are subjected to force that compresses the second return spring on one side. The bottom separating plate and the secondary separating plate located at the bottom are on the same horizontal line as the bottom ends of the adjacent main separating plate and the secondary separating plate. As the moving mechanism drives the drive mechanism to move, the bottom separating plate and the secondary separating plate press and fix the leather material. The adjacent main separating plate and the secondary separating plate at the bottom continuously roll alternately to press and fix the leather material, thereby preventing the leather material from loosening and shifting during the cutting process of the cutting head, which would cause cutting errors.

[0020] 2. During the alternating rolling of the main separating plate and the secondary separating plate to press and fix the leather material, the central column drives the transmission column to rotate, which in turn drives the lead screw to rotate. The rotation of the lead screw separates the transmission column from the push rod through the internal threaded hole of the push rod. The push rod moves into the through hole on one side of the connecting plate and squeezes the first return spring. During the rotation of the push rod, it squeezes the torsion spring through the rotating shaft. At the same time, the push rod drives the connecting rod. The ten connecting rods pull the five main separating plates and the secondary separating plates to move in opposite directions. At this time, the main separating plate and the secondary separating plate at the bottom are in the state of pressing the leather material. By pulling the main separating plate and the secondary separating plate, the pressed leather material is separated, thereby separating the threads left by the incompletely cut leather, thus improving the cutting efficiency.

[0032] As attached Figure 1 To be continued Figure 8 As shown:

[0033] Example 1

[0034] The CNC cutting device for bed board leather includes a machine tool 1. A base plate 101 is provided on the upper surface of the machine tool 1. A moving mechanism 102 is installed at the edge of the upper surface of the machine tool 1. A drive mechanism 103 is installed on the outer side of the moving mechanism 102. A cutting head 104 is installed at the bottom of the drive mechanism 103. A transmission assembly for pressing and fixing is installed on one side of the drive mechanism 103. The transmission assembly includes a separation main plate 3, a separation sub plate 301, a center column 302, a center plate 303, a slide plate 304, a second return spring 305, a transmission column 306, and a lead screw 307.

[0035] A center plate 303 is provided on one side of the main board 3. A separation sub-plate 301 is provided on the side of the center plate 303 away from the main board 3. A second reset spring 305 is connected to one side of the separation sub-plate 301. A slide plate 304 is connected to the end of the second reset spring 305 away from the separation sub-plate 301. A center column 302 is provided on the outer side of the slide plate 304. A transmission column 306 is provided on one side of the center column 302. A lead screw 307 is installed on the side of the transmission column 306 away from the center column 302.

[0036] Among them, the central column 302 is set in the form of a pentagonal prism, and each of the five sides of the central column 302 has a groove that matches the sliding plate 304.

[0037] Ten slide plates 304 are embedded in the outer side of the central column 302 and are symmetrically arranged at the center of the central column 302. One side of each of the ten slide plates 304 is connected to the separation main board 3 and the separation sub-board 301 respectively through the second return spring 305.

[0038] Five separate mainboards 3 are arranged in a ring around the outer side of the central column 302. The five separate mainboards 3 are not attached to each other, and each of the separate mainboards 3 has a slot that matches the central plate 303 on the side of the separate sub-plate 301.

[0039] The five separate sub-boards 301 are provided with slots matching the central board 303 on the side of each of the five separate main boards 3 close to the five separate main boards 3. The side of the separate sub-boards 301 away from the separate main boards 3 is provided with a reset component for tearing and breaking. The five separate sub-boards 301 and the five separate main boards 3 are mirror images of each other at the center of the central board 303.

[0040] The leather material to be cut for the massage bed is placed on the upper surface of the base plate 101. Cutting data is transmitted to the machine tool 1. The machine tool 1, upon receiving the data, controls the moving mechanism 102 to drive the drive mechanism 103, causing the cutting head 104 to cut the leather material. The drive mechanism 103 moves the cutting head 104 downwards, which in turn moves the reset assembly downwards. This downward movement of the reset assembly then moves the main separation plate 3 and the secondary separation plate 301 downwards. The main separation plate 3 and the secondary separation plate 301 then move downwards to fit against the leather material, simultaneously applying force to the main separation plate 3 and the secondary separation plate 301. The second return spring 305 on one side is squeezed, at which time the bottom separation main plate 3 and separation sub-plate 301 are on the same horizontal line as the bottom ends of the adjacent separation main plate 3 and separation sub-plate 301. As the moving mechanism 102 drives the driving mechanism 103 to move, the bottom separation main plate 3 and separation sub-plate 301 press and fix the leather material. The adjacent separation main plate 3 and separation sub-plate 301 continuously roll alternately to press and fix the leather material, thereby preventing the leather material from loosening and shifting during the cutting process of the cutting head 104, which would cause cutting errors.

[0041] Example 2

[0042] The difference between this embodiment and embodiment 1 is that the reset assembly includes a connecting mechanism 2, a connecting plate 201, a push rod 202, a connecting rod 203, a first reset spring 204, a rotating shaft 205, and a torsion spring 206. The connecting plate 201 is installed at the bottom of the connecting mechanism 2. A torsion spring 206 is provided on one side of the connecting plate 201. One end of the torsion spring 206 is connected to the rotating shaft 205. The end of the rotating shaft 205 away from the torsion spring 206 is connected to the first reset spring 204. The end of the first reset spring 204 away from the rotating shaft 205 is connected to the push rod 202. The outer side of the push rod 202 is connected to the connecting rod 203.

[0043] Among them, the connecting plate 201 has a through hole on one side, and a torsion spring 206 is installed in the through hole;

[0044] The push rod 202 has a threaded hole at one end away from the first return spring 204 that matches the lead screw 307, and the diameter of the push rod 202 is equal to the diameter of the through hole on one side of the connecting plate 201.

[0045] Connecting rod 203 is arranged in a ring around the outer side of push rod 202. There are five connecting rods 203. The end of each of the five connecting rods 203 away from the outer side of push rod 202 is connected to one side of separation sub-plate 301. Five connecting rods 203 are connected to one side of separation main plate 3.

[0046] As the moving mechanism 102 drives the drive mechanism 103 to move, the bottom separating main plate 3 and separating secondary plate 301 press and fix the leather material. The adjacent separating main plates 3 and 301 continuously roll alternately to press and fix the leather material. During this rolling process, the central column 302 rotates once to move to the next face of the pentagonal prism. At this time, the central column 302 drives the transmission column 306 to rotate. After the transmission column 306 rotates, it simultaneously drives the lead screw 307 to rotate. The rotation of the lead screw 307 causes the transmission column 306 to separate from the push rod 202 through the internal threaded hole. 2. The push rod 202 moves into the through hole on one side of the connecting plate 201. During the movement of the push rod 202, it squeezes the first return spring 204 and squeezes the torsion spring 206 through the rotating shaft 205 during the rotation of the push rod 202. At the same time, the push rod 202 drives the connecting rod 203. The ten connecting rods 203 pull the five separating main plates 3 and separating sub-plates 301 to move in opposite directions. At this time, the separating main plates 3 and separating sub-plates 301 at the bottom are in the state of pressing the leather material. By pulling the separating main plates 3 and separating sub-plates 301, the pressed leather material is separated, thereby separating the threads left by the incompletely cut leather, thereby improving the cutting efficiency.

Many modifications and variations will be apparent to those skilled in the art.
