The loading mechanism includes a feeding device and a lifting device, while the cutting mechanism includes a chuck and a cutting machine. The feeding device comprises a feeding frame and a feeding power assembly. The lifting device is located next to the feeding frame, directly below the chuck axis. After the feeding power assembly transports the profile directly above the lifting device, the lifting device lifts the profile to a height corresponding to the chuck axis. The chuck then clamps the profile, and the cutting machine cuts the profile.

To ensure the lifting accuracy, the lifting base is fixedly connected to a servo lifting motor, the servo lifting motor is provided with a lifting gear, and the feeding frame is provided with a lifting rack.

[0004] In actual production work, in order to ensure that the chuck can move smoothly, the height of the feed rack will be limited.

[0009] Preferably, the servo lifting motor is located directly below the lifting structure, the lifting drive device is a lifting power cylinder or a lifting electric cylinder, and the two lifting drive devices are respectively arranged on both sides of the servo lifting motor.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] It should be noted that if the embodiments of the present invention involve directional indications, such as up, down, left, right, front, and back, the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0030] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features specified as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0031] like Figures 1 to 7 As shown, a profile lifting device includes a frame 1, a lifting seat 2 and a lifting structure 3; the lifting seat 2 can be vertically slidably connected to the frame 1, and a servo lifting motor 4 is provided on the lifting seat 2. A lifting gear 41 is provided on the rotating shaft of the servo lifting motor 4, and a lifting rack 5 is provided on the frame 1. The lifting gear 41 and the lifting rack 5 are meshed and connected; the lifting seat 2 is also provided with a lifting drive device 6, and the output end of the lifting drive device 6 is provided with a lifting structure 3. The lifting drive device 6 can drive the lifting structure 3 to move upward relative to the lifting seat 2 to lift the profile on the upper side of the lifting seat 2.

[0032] Compared with the profile lifting device in the prior art that only uses a servo motor to lift the profile, when the rack height is the same, since the profile lifting device in the utility model is also provided with a lifting drive device 6, which can drive the lifting structure 3 to move upward relative to the lifting seat 2, the profile lifting device in the utility model has a larger lifting range and can lift the profile to a higher height, thereby reducing the occurrence of insufficient lifting. In general, the profile lifting device in the utility model, while using the servo lifting motor 4 to ensure lifting accuracy, is conducive to expanding the profile lifting range, expanding the scope of application of the profile lifting device, ensuring smooth production, and improving production efficiency.

[0033] During lifting, the lifting drive 6 drives the lifting structure 3 upward, lifting the profile in the process. After the lifting drive 6 has driven the lifting structure 3 to its limit, the servo lift motor 4 drives the lifting gear 41 to rotate, driving itself and the lifting base 2 upward along the lifting rack 5 to lift the profile to the target height.

[0034] First, the lifting structure 3 is driven to rise by the lifting drive device 6 to lift the material, and then the servo lifting motor 4 is used to drive the profile to continue to rise, so that the profile can reach the target height under the drive of the servo lifting motor 4 to ensure the accuracy of the profile lifting, which is conducive to improving production fluency and product quality.

[0035] refer to Figure 6 and Figure 7 The profile jacking device in this embodiment is called jacking device A, and the profile jacking device in the prior art is called jacking device B. Putting jacking device A and jacking device B in the same figure for comparison can more intuitively present the beneficial effects of jacking device A.

[0036] In comparing jacking device A and jacking device B, the following premise is assumed:

[0037] (1) The height of rack 1 is the same;

[0038] (2) The height of the lifting rack 5 is the same;

[0039] (3) The height of the lifting seat 2 is the same;

[0040] (4) The relative height positions of the lifting seat 2, the servo lifting motor 4 and the lifting structure 3 are substantially the same (for the lifting device A, this refers to the relative height positions of the lifting seat 2, the servo lifting motor 4 and the lifting structure 3 when the lifting structure 3 is at the lowest height relative to the lifting seat 2).

[0041] exist Figure 6 In the figure, the left and right figures respectively show the structural schematic diagrams of the lifting device A and the lifting device B when the lifting structure 3 is at the lowest position; Figure 7 The left and right figures in the figure respectively show the structures of lifting device A and lifting device B when the lifting structure 3 is at its highest position. It can be seen that lifting device A, i.e., the profile lifting device in this embodiment, has a larger lifting range, making it more applicable and more conducive to lifting profiles to the required height, ensuring smooth production.

[0042] Specifically, a lifting rail is provided on the frame 1, and a lifting slider 21 is provided on the lifting seat 2. The lifting seat 2 is clamped on the lifting rail through the lifting slider 21 and can move along the lifting rail.

[0043] In some specific embodiments, reference Figure 2 The servo lifting motor 4 is located directly below the material lifting structure 3. The material lifting drive device 6 is a material lifting power cylinder or a material lifting electric cylinder. The two material lifting drive devices 6 are respectively arranged on both sides of the servo lifting motor 4. The output ends of the two material lifting drive devices 6 are fixedly connected to the material lifting structure 3.

[0044] The servo lifting motor 4 is arranged on the lower side of the lifting structure 3, so that when the servo lifting motor 4 drives the lifting seat 2 to move up and down, it is beneficial to maintain force balance, so that the lifting seat 2 is not prone to side deviation or even tipping, which is beneficial to extending the service life; and the two lifting drive devices 6 are arranged on both sides of the servo lifting motor 4, which is beneficial to making the lifting structure 3 evenly stressed and balanced, and is also beneficial to reducing the overall height of the profile lifting device.

[0045] Specifically, the ejection driving device 6 is an ejection cylinder 61 .

[0046] The above-mentioned ejection power cylinder includes an ejection hydraulic cylinder in addition to the ejection air cylinder 61. Compared with the ejection hydraulic cylinder and the ejection electric cylinder, the ejection air cylinder 61 has the advantages of low cost and high stability, which is conducive to reducing production costs and extending service life.

[0047] In some other embodiments, the ejection drive device 6 includes two ejection hydraulic cylinders or two ejection electric cylinders.

[0048] In some other embodiments, a "motor + rack and pinion module" may be used to drive the lifting structure 3 to move up and down relative to the lifting seat.

[0049] In some specific embodiments, reference Figure 2 and Figure 5 A lifting rail 33 is provided on the lifting seat 2, and a lifting slider 32 is provided on the lifting structure 3. The lifting structure 3 is clamped on the lifting rail 33 through the lifting slider 32 and can move along the lifting rail 33.

[0050] The setting of the ejection slide rail 33 and the ejection slider 32 provides a guide for the ejection structure 3 when the ejection lifting device drives the ejection structure 3 to move up and down, so that the ejection structure 3 can move stably, which is beneficial to improving the stability of the ejection and ensuring production quality.

[0051] In some specific embodiments, reference Figure 2 and Figure 3 The ejection structure 3 includes an ejection plate 35, and a ejection cross bar 31 is provided on the upper side of the ejection plate 35. The ejection plate 35 is also provided with a transmission connection clamping assembly and a clamping drive device 9. The clamping assembly includes at least two clamping parts 7, and the clamping parts 7 protrude from the ejection cross bar 31. The clamping drive device 9 can drive the two clamping parts 7 to move closer or farther away synchronously to clamp or release the profile on the ejection cross bar 31.

[0052] During ejection, the ejection drive 6 pushes the ejection plate 35 upward, causing the ejection bar 31 to lift the profile on the loading rack. Then, the clamping drive 9 drives the two clamping members 7 to move closer or farther away synchronously, thereby clamping or releasing the profile supported on the ejection bar 31. The synchronous approach of the clamping members 7 is conducive to positioning the profile directly below the chuck axis during clamping, which is conducive to improving loading accuracy and production quality.

[0053] In some specific embodiments, reference Figure 2 、 Figure 3 and Figure 7 The clamping member 7 includes a vertically extending clamping portion 71 and a horizontally extending transmission portion 72. The transmission portion 72 can be horizontally slidably connected to the top plate 35. The two transmission portions 72 are arranged in the vertical direction. A clamping rack 721 is provided on the transmission portion 72. A clamping gear 8 is provided on the top plate 35. The clamping gear 8 is located between the two clamping racks 721 and is meshed with the two clamping racks 721. The clamping drive device 9 is transmission-connected to one of the transmission portions 72.

[0054] Using the gear rack motion module to drive the two clamping members 7 to move closer to or away from each other is beneficial to improving the synchronization of the movement of the two clamping members 7. At the same time, since only one of the transmission parts 72 needs to be driven to move, the structure of the clamping drive device 9 can be simplified and the cost can be reduced.

[0055] Specifically, the material clamping drive device 9 is a material clamping drive cylinder 91, which is arranged on the lower side of the two transmission parts 72, so that the profile lifting device has a compact structure, which is conducive to improving structural stability.

[0056] Two horizontally extending material clamping rails 34 are also provided on the top plate 35. The two material clamping rails 34 are arranged in a vertical direction. The transmission parts 72 of the two material clamping members 7 are each equipped with a material clamping slider 722. The two material clamping members 7 are clamped to the material clamping rails 34 by the material clamping sliders 722 in a one-to-one correspondence and can move along the material clamping rails 34, providing guidance for the horizontal movement of the material clamping members 7, ensuring that the material clamping members 7 remain stable during movement.

[0057] In combination with the above content, the specific structure of the profile lifting device in this embodiment is as follows:

[0058] The front side of the lifting seat 2 is provided with two lifting rails 33 extending vertically and arranged in the horizontal direction. The lifting plate 35 is slidably connected to the lifting rails 33 through the lifting slider 32. The lifting seat 2 is provided with an avoidance hole, which is located on the lower side of the lifting plate 35. The main part of the servo lifting motor 4 is fixedly set on the front side of the lifting seat 2. The rotating shaft of the servo lifting motor 4 passes through the avoidance hole and extends to the back side of the lifting seat 2. The rotating shaft of the servo lifting motor 4 is provided with a lifting gear 41, which is located on the back side of the lifting seat 2. The side of the frame 1 close to the lifting seat 2 is provided with two lifting rails extending vertically and arranged in the horizontal direction. A vertically extending lifting rack 5 is provided between the two lifting rails. A lifting slider is provided on the back side of the lifting seat 2. The lifting seat 2 is slidably connected to the lifting rails through the lifting slider 21. The lifting gear 41 is meshed with the lifting rack 5. Two ejection cylinders 61 are also provided on the front side of the lift base 2. These two ejection cylinders 61 are located on either side of the servo lift motor 4. The piston rods of the ejection cylinders 61 are connected to the ejection plate 35 to drive the ejection plate 35 to move along the ejection slide rail 33. A ejection bar 31 is provided on the upper side of the ejection plate 35. A clamping member 7 and a clamping drive device 9 are provided on the ejection plate 35 in a transmission connection to clamp the profile in place.

[0059] Before the ejection cylinder 61 lifts the ejection plate 35, the position of the ejection bar 31 can be lower than the upper side of the lifting seat 2 or higher than the upper side of the lifting seat 2; and after the ejection cylinder 61 lifts the ejection plate 35, the ejection bar 31 is higher than the upper side of the lifting seat, so that the ejection bar 31 can lift the profile on the upper side of the lifting seat 2.

[0060] This embodiment also discloses a profile feeding mechanism, including the above-mentioned profile lifting device.

[0061] In some specific embodiments, reference Figure 1 and Figure 4The profile feeding mechanism also includes a feeding device and a sensing device 102. The feeding device includes a feeding rack, a driving sprocket, a driven sprocket, a chain 10 and a feeding drive device. The feeding rack is a frame 1. The driving sprocket and the driven sprocket are both rotatably connected to the feeding rack. The feeding drive device is transmission-connected to the driving sprocket. The chain 10 is wound around the driving sprocket and the driven sprocket. A profile placement position 101 is provided on the chain 10. The feeding device is used to transport the profile to the upper side of the profile lifting device; the sensing device 102 is communicatively connected to the feeding drive device, and the sensing end of the sensing device 102 corresponds to the position of the jacking structure 3, so that when the profile is transported to the upper side of the jacking structure 3, the chain 10 stops.

[0062] Specifically, the feed drive device is a feed drive motor. The sensing device 102 is an infrared sensor located midway between the clamping portions 71 of the two clamping members 7, with its emitting end facing upward. When the profile reaches directly above the ejector plate 35, with its axis positioned midway between the two clamping portions 71, the infrared sensing device 102 receives a profile arrival signal and sends a stop signal to the feed drive device, causing the chain 10 to stop, and the profile to also stop moving. Finally, the profile lifting device lifts the profile to a height corresponding to the chuck.

[0063] In the prior art, in order to ensure the accuracy of feeding, the profile is fed to the middle position of the two clamping members 7 as much as possible, and a servo motor is used in the feeding drive device. The effect that the servo motor can achieve is: the profile is fed to any position on the conveying rack more accurately. However, in actual production, it is only necessary to position the profile when it reaches the top of the clamping structure. If a servo motor with a higher cost is used for positioning, it is actually excessive and wasteful. Moreover, there are many parts related to the servo motor on the feeding device, and the range is large. If maintenance is required, it will take a long time. In this embodiment, the form of "ordinary motor + induction device 102" is adopted to perform more precise positioning when the profile reaches the top of the clamping structure. This is more targeted and helps to reduce costs and improve economic benefits.

[0064] In this embodiment, when the lifting structure 3 is at the lowest height position, the overall height of the profile lifting device is lower than the profile placement position 101, so that the profile lifting device will not hinder the feeding device from conveying the profile.

[0065] This embodiment also discloses a profile processing device, including the above-mentioned profile feeding mechanism.

[0066] In some specific embodiments, reference Figure 8 The profile processing equipment also includes a cutting mechanism 20, a grinding mechanism 30, a chamfering mechanism 40 and a coding mechanism 50, and the profile feeding mechanism is used to transport the profile to the cutting mechanism 20.

[0067] After the profile is loaded onto the cutting mechanism 20, the cutting mechanism 20 cuts the profile according to the set requirements, and then transports the cut profile to the grinding mechanism 30, the chamfering mechanism 40 and the coding mechanism 50 in sequence for grinding, chamfering and coding, which is beneficial to improving the profile processing efficiency.

[0068] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
