Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, specifically to a cutting device for wood-plastic composite flooring substrate. Background Technology

[0002] The wood-plastic composite flooring substrate cutting device is a specialized piece of equipment used to cut and process the substrate of wood-plastic composite flooring (a board made of composite materials such as plastic and wood fiber).

[0003] A search revealed Chinese patent application CN202420495482.1, which discloses an environmentally friendly flooring substrate cutting device, relating to the field of flooring cutting technology. This invention includes a base, with a vertical plate fixedly connected to the top of the base near the center of one side. An L-frame is fixedly connected to the side of the vertical plate near the center of the top. A mounting box is fixedly connected to the bottom of the L-frame. A controller is fixedly connected to the center of the side wall of the mounting box. A top groove is symmetrically formed inside the top of the mounting box near the center, and a connecting plate is slidably connected inside the top groove. A baffle is fixedly connected to the bottom of the connecting plate. A sliding plate is slidably connected to the center of the front end of the vertical plate. This invention solves the problem that cutting blades in cutting devices are typically directly connected to the motor, making disassembly and replacement cumbersome when the cutting blade is damaged and needs replacement, by pressing down the locking pin in the slot. The interaction between the locking pin, the limiting groove, the spring, the sliding column, and the sliding shaft addresses this issue.

[0004] The aforementioned prior art mainly involves quick disassembly and replacement of the cutting blade by inserting and snapping it in place, allowing for timely replacement when the cutting blade is damaged. While this replacement method is relatively convenient, the use of a plug and the simple combination of a single spring and a locking rod for positioning can easily cause slight wobbling of the cutting blade due to gaps in the insertion. Since the cutting blade needs to rotate at high speed during operation, unstable installation and wobbling can cause significant damage to subsequent cutting. Utility Model Content

[0005] The purpose of this invention is to provide a cutting device for wood-plastic composite flooring substrates, which solves the problem that in the existing wood-plastic composite flooring substrate cutting devices, the installation stability is poor when the cutting blade is replaced or disassembled, and it is easy to shake, which in turn affects subsequent processing.

A spring is sleeved on the outside of the positioning rod, and the end of the spring near the locking plate is fixedly connected to the locking plate, while the end of the spring away from the locking plate is fixedly connected to the fixing rod.

[0009] The above technical solution utilizes multiple sets of clamping plates to restrict the positioning of the support cylinder and the insertion rod.

[0010] As a preferred embodiment of the above technical solution, the conventional component includes a connecting plate rotatably connected to one end of the card plate, and a first collar rotatably connected to the end of the connecting plate away from the card plate, with the inner side of the first collar sleeved on the outer side of the fixing rod.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0018] like Figure 1 - Figure 5As shown, this utility model provides a technical solution: a cutting device for wood-plastic composite flooring substrate, including a base plate 1, a support 11 is provided on the upper side of one end of the base plate 1, and a motor 12 is fixedly connected to one end of the support 11. A cutting blade 13 is provided at the end of the motor 12 away from the support 11. A support assembly 2 is provided on the outside of the output shaft of the motor 12, and the support assembly 2 includes a rotating shaft 21 sleeved on the outside of the output shaft of the motor 12. A support cylinder 22 is fixedly connected to the end of the rotating shaft 21 away from the motor 12, and one side of the support cylinder 22 is fixedly connected to the output shaft of the motor 12. A flange 23 is fixedly connected to the outside of the end of the rotating shaft 21 away from the support cylinder 22. The support cylinder 22 is rotatably connected to the motor 12 at one end. The support cylinder 22 is equipped with a pin assembly 3 at the end away from the rotating shaft 21. The pin assembly 3 is equipped with a locking assembly 4 at the end near the rotating shaft 21. The locking assembly 4 is equipped with a traditional assembly 5 at one end. The traditional assembly 5 is equipped with a tension assembly 6 at the end away from the locking assembly 4. The lower end of the bracket 11 is equipped with a lifting assembly 7. By cooperating with the support assembly 2 and the pin assembly 3, the stability of the installation after the replacement of the cutting blade 13 can be effectively improved, avoiding safety hazards caused by the high-speed rotation of the cutting blade 13. At the same time, the replacement operation is more convenient and the replacement efficiency is faster.

[0019] like Figure 4 and Figure 5 As shown, the pin assembly 3 includes a pin 31 inserted into the support cylinder 22 at the end away from the rotating shaft 21, and a fixing rod 32 is fixedly connected to the inner side of the middle end of the pin 31.

[0020] like Figure 5 As shown, the locking assembly 4 includes a locking plate 41 inserted inside the end of the fixing rod 32 near the rotating shaft 21, and the end of the locking plate 41 away from the insertion rod 31 is inserted into the support cylinder 22. A positioning rod 42 is inserted inside the end of the locking plate 41 away from the support cylinder 22, and the end of the positioning rod 42 away from the locking plate 41 is fixedly connected to the fixing rod 32. A spring 43 is sleeved on the outside of the positioning rod 42, and the end of the spring 43 near the locking plate 41 is fixedly connected to the locking plate 41, and the end of the spring 43 away from the locking plate 41 is fixedly connected to the fixing rod 32. During the insertion process, the support cylinder 22 will squeeze multiple sets of locking plates 41, so that the locking plates 41 compress the spring 43 under the restriction of the positioning rod 42. When the insertion of the support cylinder 22 is finished, the elastic potential energy of the spring 43 pushes the locking plate 41 to pop out under the restriction of the positioning rod 42 and insert it into the support cylinder 22 to lock and fix the insertion rod 31.

[0021] like Figure 5 As shown, the conventional component 5 includes a connecting plate 51 rotatably connected to one end of the card plate 41, and a first collar 52 rotatably connected to the end of the connecting plate 51 away from the card plate 41. The inner side of the first collar 52 is sleeved on the outer side of the fixed rod 32. After the first collar 52 moves, it pulls the connecting plate 51, causing it to pull the card plate 41 to move.

[0022] like Figure 2 and Figure 3 As shown, the tension assembly 6 includes a first collar 52 with a pull plate 61 fixedly connected to the end away from the connecting plate 51, and a second collar 62 fixedly connected to the end of the pull plate 61 away from the first collar 52. Positioning plates 63 are fixedly connected to the outer sides of both ends of the second collar 62.

[0023] like Figure 2 and Figure 3 As shown, two sets of positioning plates 63 are fixedly connected to both ends of the second collar 62, and the pull plate 61 is set through the insertion rod 31 at the end away from the first collar 52. The inner side of the second collar 62 is sleeved on the outer side of the insertion rod 31. Pulling the positioning plates 63 on both sides causes the second collar 62 and the pull plate 61 to move under the restriction of the fixed rod 32. Then the pull plate 61 pulls the first collar 52 to move.

[0024] like Figure 1 As shown, the lifting assembly 7 includes a hydraulic telescopic rod 71 fixedly connected to the middle of the lower side of the bracket 11, and the lower end of the hydraulic telescopic rod 71 is fixedly connected to the base plate 1. Positioning telescopic rods 72 are provided on both sides of the hydraulic telescopic rod 71, and the lower end of the positioning telescopic rods 72 is fixedly connected to the base plate 1. The upper end of the positioning telescopic rods 72 is fixedly connected to the bracket 11. Under the support and restriction of the positioning telescopic rods 72, the hydraulic telescopic rod 71 is activated to adjust the height of the bracket 11.

[0025] Working principle: When replacing the cutting blade 13, first pull the positioning plates 63 on both sides to move the second ring 62 and the pull plate 61 under the restriction of the fixed rod 32. Then, the pull plate 61 pulls the first ring 52 to move. After the first ring 52 moves, it pulls the connecting plate 51 to move the clamping plate 41. After the clamping plate 41 moves, it is pulled out of the support cylinder 22 and the spring 43 is compressed under the restriction of the positioning rod 42. Then, the cutting blade 13 can be pulled to pull out the insertion rod 31 and remove the support cylinder 22. During subsequent installation, the cutting blade 13 drives the insertion rod 31 to be inserted into the support cylinder 22. During the insertion process, the support cylinder 22 will be compressed. Multiple sets of clamping plates 41 are used to compress the spring 43 under the restriction of the positioning rod 42. When the support cylinder 22 is inserted, the elastic potential energy of the spring 43 pushes the clamping plate 41 to pop out and insert into the support cylinder 22 under the restriction of the positioning rod 42 to fix the insertion rod 31. When in use, the motor 12 is started by the support of the bracket 11. After the motor 12 is started, the output shaft drives the support cylinder 22, the insertion rod 31 and the cutting blade 13 to rotate under the support and assistance of the rotating shaft 21 and the flange 23. The height of the bracket 11 can also be adjusted by starting the hydraulic telescopic rod 71 under the support and restriction of the positioning telescopic rod 72.

[0026] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
