Description

Technical Field

[0001] The utility model relates to a material end cutting device, in particular to a material end cutting device used for simultaneously cutting and trimming adjacent ends of two continuous and equidistant profiles, belonging to the technical field of material cutting. Background Art

[0002] In order to improve production efficiency and processing quality, existing profiles such as bars or plates are cut to fixed length or at the ends by continuous assembly line cutting. A common example is the cutting assembly of a profile cutting machine with patent announcement number CN204725548U, which controls the fixed length of the material through a displacement detection mechanism and a magnetic scale, and then drives the saw blade to feed and cut through the cutting table. After the cutting is completed, it resets and performs a second cutting, thereby achieving continuous cutting and improving cutting accuracy and cutting efficiency.

[0003] However, in actual applications, there will be various different cutting environments. For example, the profile is coated or edged before cutting. In the coating or edge-wrapping process, the coating or edge-wrapping body is generally transparent or translucent material and has a continuous length. Profiles of different lengths are fed through the assembly line, and are directly adhered, physically or chemically synthesized with the coating or edge-wrapping body, and then the edges of the profiles are trimmed.

[0004] When trimming the ends of a profile, using traditional cutting equipment means that the assembly line can only cut and trim a single end. Using displacement detection mechanisms or magnetic scales for fixed-length position control is no longer practical due to gaps between profiles. Simultaneously positioning and cutting both ends of a profile requires a longer cutting machine, occupies more space, and is more expensive. Furthermore, the positioning accuracy of the profile ends is low, making cutting difficult, inefficient, and prone to waste. Summary of the Invention

[0005] In response to the above-mentioned deficiencies in the prior art, the present invention proposes a material end cutting device for efficiently shaping and cutting the ends of continuous and equidistantly spaced profiles. The device occupies a small space, is low in cost, and is suitable for promotion.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the utility model is as follows: a material end cutting device is mainly used for simultaneously shaping and cutting the adjacent axial ends of the profiles that are continuously fed and equidistantly spaced on the assembly line. The device includes a device body, the device body has a first drive mechanism for driving the profile to continuously move and feed in the axial direction, a gap detection sensor for detecting the position of the gap between adjacent profiles, and a cutting mechanism for synchronously cutting the adjacent head and tail ends of adjacent profiles, wherein the cutting mechanism includes:

[0007] A cutting platform that can move synchronously with the axial direction of the profile and can form a reference positioning for the bottom surface of the profile, a second driving mechanism that drives the axial movement and axial reset of the cutting platform, a clamping mechanism arranged on the cutting platform and can clamp the adjacent profiles on the cutting platform, and a double saw blade arranged on the cutting platform and can synchronously cut the adjacent head and tail ends of adjacent profiles.

[0008] Furthermore, a double slide rail is provided on the main body of the device, and the cutting platform is slidably engaged on the double slide rail through a slide rail slider. The second driving mechanism includes a rack axially fixed on the cutting platform, a servo motor positioned on the main body of the device, and a gear fixedly connected to the output shaft of the servo motor and connected to the teeth of the rack.

[0009] Furthermore, a bracket is fixedly positioned on the cutting platform, a cutting cylinder is positioned on the bracket, a cylinder rod of the cutting cylinder is relatively fixedly connected to a cutting motor, the double saw blades are fixedly connected to the output shaft of the cutting motor, and can form vertical cutting with the profile.

[0010] Furthermore, a cutting clearance hole is provided on the cutting platform, and the cutting clearance hole is located in the cutting feed direction of the double saw blades.

[0011] Furthermore, the profiles on the production line are all uniformly positioned under a cover or wrapping piece formed of a transparent flexible material and continuous and uninterrupted.

[0012] Furthermore, the clamping mechanisms all use clamping cylinders, which are controlled synchronously or independently.

[0013] Furthermore, the first driving mechanism is a plurality of transmission wheels, which are arranged along the feeding direction of the profile, and the plurality of transmission wheels are connected by a same driving motor through chain and sprocket transmission.

[0014] Furthermore, the gap detection sensor includes a laser sensor, which is positioned behind the feed of the cutting platform, and the laser emitting end of the laser sensor is below the profile and the laser receiving end is above the profile.

[0015] Furthermore, a controller is included, wherein the output end of the gap detection sensor is connected to an input end of the controller, and the controller is electrically controlled and connected to the first driving mechanism, the clamping mechanism, the servo motor, the cutting motor, and the cutting cylinder respectively.

[0016] Furthermore, the profile is a wooden profile; the covering or cladding is a decorative tape, adhesive strip or protective tape integrally formed of a transparent or translucent material.

[0017] The beneficial effects of the present invention are as follows: when cutting the end of a profile, the cutting platform moves synchronously with the profile, and the clamping mechanism is used to clamp and limit the adjacent profiles respectively, and then the double saw blades perform synchronous cutting on the head and tail ends of the adjacent profiles. The efficiency is high and the device does not take up too much space. When the cutting action is completed, the cutting platform is reset and the next cutting is performed. This cycle is repeated to achieve the purpose of continuously cutting and shaping the end of the profile. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present invention will be described in further detail below with reference to specific embodiments and accompanying drawings.

[0022] A kind of Figure 1-3 The material end cutting device shown is mainly used for simultaneously shaping and cutting the axially adjacent ends of the profiles 2 that are continuously fed and equidistantly spaced on the production line. At the same time, it can also perform axial end cutting on the profiles 2 on continuous and non-interrupted coverings or claddings. The profiles 2 are continuously and axially spaced. It includes a device body 1, which has a first drive mechanism that drives the profiles 2 to continuously move in the axial direction, a gap detection sensor 14 that detects the position of the gap between adjacent profiles 2, and a cutting mechanism that performs end synchronous cutting on adjacent ends of adjacent profiles 2, wherein the cutting mechanism includes:

[0023] A cutting platform 6 that can move axially synchronously with the profile 2 and can form a reference positioning for the bottom surface of the profile 2, a second driving mechanism that drives the cutting platform 6 to move axially and reset axially, a clamping mechanism 8, 9 that is arranged on the cutting platform 6 and can press the adjacent profiles 2 to be limited on the cutting platform 6, and a double saw blade 10 that is arranged on the cutting platform 6 and can synchronously cut the adjacent ends of the adjacent profiles 2.

[0024] The device of the present invention can be used to shape and cut the ends of various profiles, such as metal profiles and wooden profiles, by changing the material of the dual saw blades 10. This embodiment is described specifically using a wooden profile as an example. Specifically, the profile 2 is a wooden profile, and the covering or cladding is a transparent or translucent decorative tape, adhesive strip, or protective tape integrally formed therefrom.

[0025] This device can be used to automatically process processes such as bonding profiles 2, covers, or cladding, achieving streamlined production, improving operational efficiency, and reducing labor costs. The spacing between adjacent profiles 2 varies depending on the frequency of profile loading, the various processes, and the movement of the profiles. Therefore, using traditional fixed-length control for batch cutting can easily lead to problems, resulting in profile scrapping or inability to achieve effective end shaping.

[0026] The first drive mechanism in this case is a number of colloid-molded conveyor wheels 3, which are arranged along the feed direction of the profile 2 and are connected by a chain sprocket transmission from the same drive motor. Due to the friction between the conveyor wheels 3 and the profile 2, the drive motor drives the conveyor wheels 3 to rotate through the chain sprocket, and the friction then drives the profile 2 to continuously move forward. The colloid conveyor wheels 3 increase the friction between the two, ensuring stable transmission and preventing potential risks such as scratches on the surface of the profile 2. When it was promoted and applied at the time, this first drive mechanism could be varied, such as a side conveyor belt, as long as it could enable the profile 2 to move forward continuously.

[0027] The device body 1 is equipped with dual slide rails 5, on which the cutting platform 6 slides via slide blocks 18. The second drive mechanism includes a rack 17 axially fixed to the cutting platform 6, a servo motor 15 positioned on the device body 1, and a gear 16 fixed to the output shaft of the servo motor 15 and connected to the teeth of the rack 17. The forward and reverse rotation of the servo motor 15 controls the synchronous feeding of the cutting platform 6 and the profile 2, as well as the reset of the cutting platform 6.

[0028] A bracket 12 is fixedly positioned on the cutting platform 6, and a cutting cylinder 13 is positioned on the bracket 12. The cylinder rod of the cutting cylinder 13 is fixedly connected to the cutting motor 11. The dual saw blades 10 are fixedly connected to the output shaft of the cutting motor 11 and can form a vertical cut with the profile 2. The positioning of the dual saw blades 10 on the cutting platform 6 is controlled by a six-axis system, which realizes intelligent cutting of the profile 2. In this case, the dual saw blades 10 cut the long-axis profile 2. The cutting cylinder 13 is used for positioning, forming a two-axis control. The cylinder rod of the cutting cylinder 13 is raised and lowered to achieve the dual saw blades 10 cutting the end of the profile 2.

[0029] The cutting platform 6 is provided with a cutter clearance hole (not shown) located in the cutting feed direction of the dual saw blades 10 to prevent damage to the cutting platform 6 by the dual saw blades 10 during the cutting process. At the same time, the cutter clearance hole is used to achieve unified management of cutting waste. At the same time, the saw blade distance between the dual saw blades 10 is adjustable to achieve synchronous cutting of different gaps between adjacent profiles 2. The spacing between the dual saw blades 2 can be adjusted by, for example, bushings, adjustment nuts, etc.

[0030] In this embodiment, the clamping mechanisms 8 and 9 both utilize clamping cylinders, which can be controlled synchronously or independently. Depending on the processing requirements, the clamping actions of the clamping cylinders can be synchronized or independent. In this embodiment, the two clamping cylinders simultaneously clamp adjacent profiles 2, allowing the dual saw blades 10 to cut the ends of adjacent profiles 2.

[0031] The gap detection sensor 14 can also be in various forms. It mainly monitors the gap between adjacent profiles 2 and the material changes of the profile 2 itself. For example, a laser sensor is used, which is positioned behind the feed of the cutting platform 6, and the laser emitting end of the laser sensor is below the profile 2 and the laser receiving end is above the profile 2.

[0032] The device also includes a controller, which can be implemented using a conventional commercially available controller. The output end of the gap detection sensor 14 is connected to an input end of the controller, and the controller is electrically connected to the first drive mechanism, the clamping mechanisms 8 and 9, the servo motor 15, the cutting motor 11, and the cutting cylinder 13.

[0033] During operation, the first driving mechanism drives the profile 2 to move continuously in the axial direction. When passing through the gap detection sensor 14, the gap detection sensor 14 detects the gap between adjacent profiles 2 and sends the detection signal to the controller. After receiving the signal, the controller controls the servo motor 15 to rotate, drives the cutting platform 6 to move synchronously with the profile 2, and controls the clamping mechanisms 8 and 9 to clamp the adjacent profiles 2. The cutting motor 11 rotates to rotate the double saw blades 10, and the cutting is controlled by the cutting cylinder 13. After the cutting is completed, the cutting cylinder 13 controls the return position, the clamping mechanisms 8 and 9 cancel the clamping, and the servo motor 15 reverses to reset the cutting platform 6, and the cycle enters the next cutting.

[0034] Finally, the cutting in the illustrations of this case is a vertical structure, but in actual applications, it can also be applied to horizontal cutting. During the cutting process, because the intervals between adjacent profiles 2 are consistent, the subsequent double saw blades can meet the synchronous cutting of the head and tail ends between adjacent profiles 2. Therefore, it is applicable to the end cutting of independent spaced profiles, profiles with covers or claddings, etc. In addition, because the cutting platform 6 and the profile 2 operate at the same speed, the double saw blades have high cutting accuracy and flatness for the end of the profile, and the final shaping consistency of the profile is good. At the same time, the entire device can perform end cutting on profiles of different lengths or coated profiles without stopping or adjusting the machine, and the cutting efficiency is high.

Specific examples are used herein to illustrate the principles and implementation methods of the embodiments of the present invention. The description of the above embodiments is only applicable to help understand the principles of the embodiments of the present invention. At the same time, for those skilled in the art, according to the embodiments of the present invention, there may be changes in the specific implementation methods and application scopes. In summary, the contents of this specification should not be understood as limiting the present invention.
