Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of production and processing equipment for edge banding strips, in particular to a cutting mechanism for edge banding strips. Background Art
[0002] Wood boards suitable for manufacturing furniture, wooden doors, etc., often use thermosetting edge banding strips to bond the edges of the boards in the thickness direction to achieve the purpose of waterproofing and aesthetics. The edge banding process generally includes the steps of unwinding the edge banding strips, online hot-melt bonding, and online cutting, where online cutting includes cutting the head and the tail.
[0003] The online cutting step of the prior art is generally achieved in the following manner: a plate or strip (hereinafter collectively referred to as a workpiece) that has completed edge banding and is waiting to be cut is brought close to a head cutting unit, and the head end of the workpiece abuts against a cutting component of the head cutting unit so that it can be fed together with the workpiece. When the two are synchronized, the cutting component performs a cutting action to complete the cutting of the head. Simultaneously or subsequently, the cutting component of the tail cutting unit is externally driven to approach the tail end of the workpiece. When the cutting component is flush with the tail end of the workpiece, the cutting component performs a cutting action to complete the cutting of the tail.
[0004] For example, see Figure 1 As shown, a cutting mechanism including a head cutting component and a tail cutting component is described in the invention patent application with publication number CN110315618A and titled “An automatic edge banding machine for door panels with a precision cutting structure”. The head cutting component includes a sliding frame 9 that is slidably connected to the machine body 1 along the moving direction of the door panel and is located directly above the door panel. A vertically arranged lifting cylinder 10 is fixedly connected to the lower end face of the sliding frame 9. The output shaft of the lifting cylinder 10 is fixedly connected to a lifting plate 11. An abutment plate 12 is installed on the lower end face of the lifting plate 11 for abutting the front end in the moving direction of the door panel. The lifting plate 11 is slidably connected to a first cutting knife 13 for cutting the head end of the edge banding strip. The first cutting knife 13 and the abutment plate 12 are flush with the end face of the door panel. The tail cutting assembly includes a sliding block 15 and a moving cylinder 16 which are slidably connected to the lower surface of the lifting plate 11. The sliding block 15 can abut against the tail end of the door panel after sliding. The output shaft of the moving cylinder 16 is fixedly connected to the sliding block 15. The sliding block 15 is slidably connected with a second cutting knife 17 for cutting the edge banding strip. The second cutting knife 17 is parallel to the first cutting knife 13. The second cutting knife 17 and the sliding block 15 are flush with the end surface of the door panel. The lifting cylinder 10 drives the lifting plate 11 to move downward, the front end of the door panel abuts against the abutting plate 12, and drives the lifting plate 11 and the sliding frame 9 to move synchronously. The moving cylinder 16 drives the sliding block 15 to move toward the door panel, so that the abutting plate 12 and the sliding block 15 clamp the front and rear ends of the door panel; then the first cylinder 14 and the second cylinder 18 simultaneously drive the first cutting knife 13 and the second cylinder 18 to cut the front and rear ends of the door panel.
[0005] In the technical solution of the above-mentioned prior art, the head cutting assembly and the tail cutting assembly are installed together on the sliding frame, and the cutting mechanism realizes synchronous feeding with the workpiece under the push of the door panel through the abutment relationship between the abutment plate 12 and the end face of the door panel. Therefore, when the door panel collides with the cutting mechanism with a relatively large overall weight and drives the cutting mechanism to start, it is easy for the door panel to deviate from the original conveying route, the door panel is passively decelerated, or unstable situations such as jumping occur, thereby causing problems such as knife jumping and uneven cutting surface, which affects the cutting effect and shortens the service life of the cutting mechanism to a certain extent.

[0037] In order to enable those skilled in the art to better understand the technical solutions in the present application, 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, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.
[0038] Example: Refer to Figures 1 to 7The cutting mechanism of an edge banding strip shown in the figure comprises an x-axis beam 1, a first cutting unit 2, a second cutting unit 3, and a control system. The x-axis beam 1 is a rigid component of the prior art, which extends along the x-axis direction and has a track. The first cutting unit 2 is suitable for cutting the edge banding strip at the front end of the workpiece 5, and the second cutting unit 3 is suitable for cutting the edge banding strip at the rear end of the workpiece 5. The first cutting unit 2 and the second cutting unit 3 are respectively and movably arranged on the x-axis beam 1, and along the conveying direction of the workpiece 5, the first cutting unit 2 is located behind the second cutting unit 3.
[0039] With the above structure, firstly, the first cutting unit 2 and the second cutting unit 3 can actively move along the x-axis direction, and the movement of the two with the workpiece does not completely rely on the push of the workpiece, and the first cutting unit 2 and the second cutting unit 3 are respectively arranged on the x-axis beam 1, and the two move synchronously with the workpiece 5 respectively and sequentially, so the following movement of the first cutting unit 2 and the second cutting unit 3 has a relatively small effect on the conveying process of the workpiece 5, or even no effect, so that the workpiece 5 can be kept stable and fed at a uniform speed during the start and following movement of the first cutting unit 2 and the second cutting unit 3, and the knife jumping can be avoided. On the one hand, the first cutting unit 2 and the second cutting unit 3 can cut the edge banding strips at the front and rear ends of the workpiece 5 straightly, and on the other hand, it can avoid the vibration of the cutting unit during following and cutting, thereby extending the service life of the cutting unit. Secondly, by placing the first cutting unit 2 behind the second cutting unit 3, when cutting, the workpiece 5 first completes the cutting of the edge banding strip at the front end when passing through the first cutting unit 2, and then completes the cutting of the edge banding strip at the rear end when passing through the second cutting unit 3. Compared with the prior art, such a cutting sequence enables the edge banding cutting mechanism of the embodiment of the present application to achieve continuous production, thereby having higher production efficiency.
[0040] Specifically, the first cutting unit 2 includes a first base 21 , a first power source 22 , a first backing plate assembly 23 , a first cutting assembly 24 , and a first drag chain assembly 25 .
[0041] The first base 21 is arranged on the x-direction beam 1 through the first power source 22, and can move along the x-direction beam 1 driven by the first power source 22. Preferably, the first power source 22 is a magnetic suspension power assembly, so as to reduce the resistance of the first base 21 when it moves and increase its starting speed when it moves.
[0042] The first support plate assembly 23 is arranged above the conveyor line, and includes a first support plate 231, a first support plate mounting plate 232 and a first lifting power source 233. In this embodiment, the first lifting power source 233 is a gas rod, whose fixed section is fixedly arranged on the side of the first base 21 facing the workpiece 5 by screwing or welding, and its movable end is pivotally connected to one end of the first support plate mounting plate 232. A first slider structure 234 is arranged on the side of the first support plate mounting plate 232, and a first slide rail 235 is arranged on the side of the first base 21 facing the workpiece 5 by screwing or welding, so that the first support plate mounting plate 232 can move according to the cooperation between the first slider structure 234 and the first slide rail 235. The first support plate 231 is welded or screwed and mounted on the lower end of the first support plate mounting plate 232, and the abutting working surface of the first support plate 231 faces the rear end of the x-axis beam 1. After descending, the first support plate 231 abuts on the front end surface of the workpiece 5, so that the workpiece 5 can push the lower first cutting unit 2 to follow.
[0043] The first cutting assembly 24 includes a first cutting tool 241, a first cutting power source 242, and a first knife-dropping power source 243 for driving the first cutting tool 241 to move closer to or away from a cutting position. The cutting position of the first cutting tool 241 is flush with the abutting working surface of the first support plate 231. The first knife-dropping power source 243 is a swing driving member. Specifically, the first knife-dropping power source 243 includes a pivot seat 2431 mounted on the bottom surface of the first base 21, a first crank connecting rod 2432, and a driving gas rod 2433. The pivot seat 2431 is pivotally connected to a first end of the first crank connecting rod 2432, and the first end of the driving gas rod 2433 is pivotally connected to a fixed seat of the pivot seat 2431, and the second end is pivotally connected to the second end of the first crank connecting rod 2432. The first cutting power source 242 is screwed and mounted on the second end of the first crank connecting rod 2432. The first cutting tool 241 is mounted on the output end of the first cutting power source 242. The first cutting tool 241 is a circular saw blade, and the first cutting power source 242 is a motor. Therefore, when the driving air rod 2433 is extended, the first cutting tool 241 is away from the cutting position (i.e., away from the workpiece 5), and when the driving air rod 2343 is retracted, the first cutting tool 241 approaches and reaches the cutting position.
[0044] The first drag chain assembly 25 is suitable for installing electrical circuits, etc., and its fixed end is arranged on the x-direction crossbeam 1, and its movable end is arranged on the first base 21.
[0045] As a preferred embodiment, the first lifting power source 233, the first slider structure 234, and the first slide rail 235 are all arranged along the z1 direction. The z1-axis direction and the x-axis direction form an angle of 40 to 50 degrees, preferably 45 degrees. When the first lifting power source 233 pushes the first support plate 231 to descend, the first support plate 231 descends along the z1-axis direction, and forms a sub-motion in the x-axis direction and a sub-motion in the y-axis direction, and the sub-motion in the x-axis direction is opposite to the conveying direction of the workpiece 5.
[0046] The second cutting unit 3 includes a second base 31 , a second power source 32 , a second backing plate assembly 33 , a second cutting assembly 34 , and a second drag chain assembly 35 .
[0047] The second base 31 is arranged on the x-direction beam 1 through the second power source 32, and can move along the x-direction beam 1 driven by the second power source 32. Preferably, the second power source 32 is a magnetic suspension power assembly, so as to reduce the resistance of the second base 31 when it moves and increase its starting speed when it follows.
[0048] The second support plate assembly 33 is arranged above the conveyor line, and includes a second support plate 331, a second support plate mounting plate 332, and a second lifting power source 333. In this embodiment, the second lifting power source 333 is a gas rod, whose fixed section is fixedly arranged on the side of the second base 31 facing the workpiece 5 by screwing or welding, and its movable end is pivotally connected to one end of the second support plate mounting plate 332. A second slider structure 334 is arranged on the side of the second support plate mounting plate 332, and a second slide rail 335 is arranged on the side of the second base 31 facing the workpiece 5 by screwing or welding, so that the second support plate mounting plate 332 can move according to the cooperation between the second slider structure 334 and the second slide rail 335. The second support plate 331 is welded or screwed to the lower end of the second support plate mounting plate 332, and the abutting working surface of the second support plate 331 faces the front end of the x-axis beam 1. After the second cutting unit 3 and the workpiece 5 are co-moving, the second support plate 331 descends, and the second support plate 331 abuts on the rear end surface of the workpiece 5.
[0049] The second cutting assembly 34 includes a second cutting tool 341, a second cutting power source 342, and a second cutting power source 343 for driving the second cutting tool 341 to approach or move away from the cutting position, and the cutting position of the second cutting tool 341 is flush with the abutting working surface of the second support plate 331. The second cutting power source 343 is a swing driving member. The second cutting tool 341 is a circular saw blade, and the second cutting power source 342 is a motor. Preferably, the second cutting power source 343 uses the same structure as the first cutting power source 243, and drives the second cutting tool 341 to the cutting position in a swinging manner.
[0050] The second drag chain assembly 35 is suitable for installing electrical circuits, etc., and its fixed end is arranged on the x-direction crossbeam 1, and its movable end is arranged on the second base 31.
[0051] As a preferred embodiment, the second lifting power source 333, the second slider structure 334, and the second slide rail 335 are all arranged along the z2 direction. The z2-axis direction and the x-axis direction form an angle of 40 to 50 degrees, preferably 45 degrees. When the second lifting power source 333 pushes the second support plate 331 to descend, the second support plate 331 descends along the z2-axis direction, and forms a sub-motion in the x-axis direction and a sub-motion in the y-axis direction, and the sub-motion in the x-axis direction is in the same direction as the conveying direction of the workpiece 5.
[0052] As a preferred embodiment, a positioning sensor 4, such as an infrared positioner, is provided on the x-axis beam 1 behind the first cutting unit 2, that is, at the beginning of the conveying direction of the workpiece 5. The positioning sensor 4 is suitable for sensing the approach of the workpiece 5.
[0053] As a preferred embodiment, a buffer gas rod 6 is provided at each end of the x-axis crossbeam 1 to serve as a retreat limit for the first cutting unit 2 and as a follow-up limit for the second cutting unit 3 .
[0054] During operation, the workpiece 5 is delivered to the cutting mechanism working area of the edge banding strip corresponding to the x-axis crossbeam 1 by any conveyor line of the prior art, such as a vacuum adsorption conveyor line. Those skilled in the art know that the conveyor line passes through the cutting mechanism of the edge banding strip along the x-axis direction; first, the positioning sensor 4 senses the approach of the workpiece 5, the workpiece 5 continues to feed, and at the same time, the first support plate 231 drops to the front of the workpiece 5; then, the front end surface of the workpiece 5 touches the abutting working surface of the first support plate 231, and under the push of the workpiece 5, the first cutting unit 2 is fed synchronously with the workpiece 5, and the first cutting tool 241 is driven by the first cutting power source 243 to drop the first cutting tool 241 from And cut off the edge strip at the front end of the workpiece 5; then, the first cutting unit 2 is reset in the reverse direction (in the x-axis direction opposite to the conveying direction of the workpiece 5), at the same time, the workpiece 5 continues to feed, and the second power source 32 drives the second cutting unit 3 to follow, and the second support plate 331 drops to the rear of the workpiece 5. When the second cutting unit 3 catches up with the workpiece 5 and is at the same speed as it, the second support plate 331 abuts against the rear end surface of the workpiece 5, and the second cutting tool power source 343 drives the second cutting tool 341 to drop the tool to cut off the edge strip at the rear end of the workpiece 5; finally, the workpiece 5 is processed or enters the next process, and the second cutting unit 3 is reset in the reverse direction.
[0055] Obviously, the workpiece 5 only needs to push the first cutting unit 2 to follow. Compared with the overall push in the prior art, the weight of the first cutting unit 2 is smaller. At the same time, the first power source 22 is a magnetic suspension assembly, so the workpiece 5 is subjected to less resistance when pushing the first cutting unit 2 to follow, and the first cutting unit 2 accelerates faster, thereby effectively avoiding the deceleration and jumping of the workpiece 5 when the workpiece 5 contacts and pushes the first cutting unit 2, as well as the uneven cutting caused by the deceleration and jumping, and can extend the service life of the first cutting unit 2. At the same time, the second cutting unit 3 moves autonomously and follows the workpiece 5, and approaches and abuts in the form of the second cutting unit 3 chasing the rear end face of the workpiece 5, thereby ensuring the feeding stability of the workpiece 5 during the following process of the two, avoiding the deceleration and jumping of the workpiece 5, as well as the uneven cutting caused by the deceleration and jumping, and can extend the service life of the second cutting unit 3.
[0056] Furthermore, the edge banding cutting mechanism of the present case adopts the first cutting unit 2 to first cut the edge banding at the front end of the workpiece 5 behind the second cutting unit 3, and the second cutting unit 3 then cuts the edge banding at the rear end of the workpiece 5 at the front. Therefore, compared with the technical solution of the prior art in which the first cutting unit 2 and the second cutting unit 3 cut simultaneously at the front and rear of the conveying direction respectively, continuous production can be achieved, thereby improving production efficiency and automation.
