Description

Technical Field

[0001] This utility model belongs to the field of plastic window frame processing technology, and in particular relates to a plastic profile window profile processing device. Background Technology

[0002] Plastic windows are a type of window that uses plastic profiles, often aluminum-plastic alloy, as the window frame. Unlike aluminum alloy windows, plastic windows have advantages such as lower cost and lighter weight, but their durability is lower than that of aluminum alloy windows.

[0003] In the production process of plastic window frames, the window frame profiles are first cut to specific dimensions. During the cutting process, the ends of the window frame profiles need to be beveled at a 45-degree angle to facilitate the subsequent installation of corner brackets. Therefore, in actual production, profile blanks of a certain length often need to be continuously pushed onto the cutting table for cutting into profiles of specific lengths according to the required dimensions.

[0004] When the profile blank is long, the feeding and cutting need to be carried out by an auxiliary feeding device. The current auxiliary feeding device uses a frame and a rotating roller installed on the frame to feed the material. When the end of the profile extends into the cutting table, the profile is first pushed against the frame (to keep the profile cutting stable) and the end of the profile is cut at a 45-degree angle. Then the operator pulls the profile back to the center of the rotating roller and continues to push it for a certain length until the profile blank is cut into specific lengths.

[0005] Therefore, throughout the entire process, operators need to continuously push the profile forward, push it to the side to position it, and then push it to the side again to continue feeding. Frequent pushing by the operator is required throughout the entire process.

[0006] A rotary roller feeder is a device that can horizontally convey rod-shaped or bar-shaped materials. It uses a self-rotating roller to assist in pushing longer rods or bars. However, in actual applications, it cannot push profiles because profiles need to be pushed to a tight position during cutting to facilitate cutting by the cutting wheel of the cutting equipment. After cutting, the profile needs to be reset. Therefore, although current rotary roller feeders can feed automatically, they cannot meet the needs of profile processing. As a result, they cannot be used in workshop production and the more primitive, inefficient, and labor-intensive manual pushing method is still used for feeding and cutting. Utility Model Content

[0007] Based on the above background, the purpose of this utility model is to provide a plastic profile window profile processing device.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A plastic profile window profile processing device includes a profile pushing mechanism, which includes a frame and a pushing structure mounted on the frame for transversely conveying the profile, and also includes a plurality of side pushing units mounted on the frame.

[0010] The side-pushing unit includes a pair of cooperating fork-pushing structures, which are used to push the profile longitudinally.

[0011] The shift fork pushing structure includes a shift push plate and a pushing structure that drives the shift push plate to push the profile.

[0012] The push plate is equipped with an anti-warping structure to prevent the profile from warping.

[0013] Preferably, the pushing structure includes active push rollers installed at both ends of the frame, and a motor for driving the active push rollers to rotate is installed on the frame;

[0014] It also includes several auxiliary push rollers that are rotatably connected between the frames.

[0015] Preferably, a plurality of connecting beam supports are fixedly installed at the lower end of the frame.

[0016] Preferably, the side push unit further includes a slide rail that slidably connects the push plates on both sides;

[0017] The slide rail is fixedly connected to brackets at both ends. The bottom of the brackets is mounted on the frame via a height adjustment structure, which adjusts the height of the push plate.

[0018] Preferably, the high-adjustment structure includes a plurality of high-adjustment screws fixedly installed at the bottom of the bracket, and the high-adjustment screws are slidably connected to the frame;

[0019] The high-adjustment screw is threaded with a pair of high-adjustment nuts positioned at the top and bottom of the frame.

[0020] Preferably, the push plate includes a U-shaped push plate portion, and push arms are integrally formed on both sides of the U-shaped push plate portion;

[0021] The top of the U-shaped push plate is integrally formed with a protrusion, which is slidably connected to the slide rail.

[0022] Preferably, the pushing structure includes pushing cylinders that are fixedly mounted on the bracket, and a piston rod bracket is integrally formed on the top of the protrusion, with the piston rod of the pushing cylinder fixedly mounted on the piston rod bracket.

[0023] Preferably, each push arm is equipped with an anti-tilting structure with adjustable height.

[0024] Preferably, the anti-tilting structure includes an anti-tilting plate, and the push arm has a height adjustment port, with the anti-tilting plate being slidably connected within the height adjustment port.

[0025] The inner end of the anti-tilting plate protrudes from the height adjustment port, which is located on the outside of the height adjustment port.

[0026] Preferably, the anti-tilting structure further includes an adjusting screw fixedly connected in the height adjustment port, and the anti-tilting plate is slidably connected to the adjusting screw;

[0027] The adjusting screw is threaded with a pair of nuts positioned at the top and bottom of the anti-tilting plate.

[0028] This utility model has the following beneficial effects:

[0029] 1. Several side-push units installed on the frame work together to push the profile to a tight position. Before cutting, the profile is pushed forward to a tight position. At this time, the rear-positioned fork push structure pushes the profile forward until it is pressed against the front fork push structure. After cutting, in order for the profile to continue feeding, the front fork push structure pushes the profile backward again until it is pushed to the center position of the active push roller and the auxiliary push roller to facilitate continued conveying.

[0030] 2. During the pushing process, the profile is pushed by a U-shaped pusher plate, and the multi-segment distribution of the side pusher units ensures that the profile is pushed synchronously along its length. For example, when the front of the profile is pushed, the rear pusher plate pushes the profile forward until it contacts the front pusher plate. The resulting side walls are held in a fixed position by the multiple pusher plates. Subsequently, the front pusher plate continues to push the rear of the profile until it returns to its original position.

[0031] 3. During the operation, first adjust the relative height of the push plate and the profile according to the method described above, ensuring that the two push arms of the push plate can smoothly contact the side wall of the profile. Then, adjust the height of the anti-tilting plate so that the bottom of the anti-tilting plate is flush with the top surface of the profile. That is, when the push cylinder pushes the push plate until the two push arms contact the side wall of the profile, the bottom of the anti-tilting plate is just slightly contacting the top surface of the profile.

[0032] 4. During the cutting process, the side walls of the profile are clamped and positioned by multiple push plates distributed front and rear. The anti-tilting plates on these push plates gently abut against the top surface of the profile. Therefore, during the downward cutting process, the anti-tilting plates limit and press down, keeping the profile in a fixed position and preventing it from tilting. Overall, the front and rear side walls of the profile are clamped and positioned by the push plates, while the top is positioned by the downward pressure from both sides of the top push plates. This method greatly increases the stability and accuracy of the profile cutting.

[0033] 5. The device disclosed in this utility model realizes the integrated design of autonomous transmission profile and side-push clamping profile, which solves the technical problems of high difficulty in feeding and difficulty in maintaining cutting accuracy during the profile feeding and cutting process.

[0044] Example 1

[0045] like Figure 1-5 As shown, a plastic profile window profile processing device includes a profile pushing mechanism. Specifically, it has the same main structure as an existing roller conveyor. The profile pushing mechanism includes a frame 1 (to increase the stability of the frame 1, several connecting beam supports 11 are fixedly installed at the lower end of the frame 1 in the existing manner) and a pushing structure 2 installed on the frame 1 for transversely conveying the profile. Specifically, as in the existing manner, the pushing structure 2 includes active push rollers 22 installed at both ends of the frame 1. A motor 23 (fixedly installed on the outer wall of the frame 1) is installed on the frame 1 to drive the active push rollers 22 to rotate. It also includes several auxiliary push rollers 21 rotatably connected between the frames 1. As in the existing manner, the rotating shafts at both ends of the active push rollers 22 and the auxiliary push rollers 21 are rotatably connected to bearings on the frame 1. The output shaft of the motor 23 is installed on the rotating shaft of the active push rollers, such as by a coupling.

[0046] During the process of pushing the profile blank, the above structure enables the automatic pushing of the profile to the cutting table of the cutting equipment located at the end of the frame 1, such as the left end, for cutting.

[0047] Before cutting, the profile needs to be pushed longitudinally to a tight position to ensure that the profile is in a positioning position during the cutting process. However, it is more difficult to push a profile with a certain length because the profile is long and cannot be pushed in a stable way.

[0048] Therefore, the present invention is improved as follows:

[0049] The plastic profile window profile processing device also includes several side push units 3 installed at the position of the frame 1; the profile is longitudinally pushed to a tight state by the cooperation of several side push units 3 arranged in the length direction of the frame 1. The profile slides longitudinally on the active push roller 22 and the auxiliary push roller 21.

[0050] Specifically, the side-pushing unit 3 includes a pair of cooperating fork pushing structures (symmetrically arranged front and rear), which are used to push the profile longitudinally.

[0051] Specifically, before cutting, the profile is pushed forward to a tight position. At this time, the fork pushing structure at the rear pushes the profile forward to abut against the fork pushing structure at the front. After cutting, in order for the profile to continue feeding, the fork pushing structure at the front pushes the profile backward again to the center position of the active push roller and the auxiliary push roller to facilitate continued conveying.

[0052] Specifically, the shift fork pushing structure includes a shift push plate 33 and a pushing structure that drives the shift push plate 33 to push the profile.

[0053] During the pushing process, the profile is pushed by the U-shaped push plate 33, and the side push unit 3 is distributed in multiple segments to push the profile synchronously along its length. That is, when the front side of the profile is pushed, the rear push plate 33 pushes the profile forward until it abuts against the push plate 33 at the front position. At this time, the two side walls formed are held in a positioning posture by the clamping of the front and rear push plates 33.

[0054] Subsequently, the front push plate 33 continues to push the rear side of the profile until the profile is reset.

[0055] Example 2

[0056] like Figure 1-5 As shown, based on the structure of Embodiment 1, the side push unit 3 further includes a slide rail 34 that slidably connects the two push plates 33 on both sides; brackets 31 are fixedly connected to both ends of the slide rail 34.

[0057] Specifically, the push plate 33 includes a U-shaped push plate portion, with push arms integrally formed on both sides of the U-shaped push plate portion; a boss portion is integrally formed on the top of the U-shaped push plate portion, and the boss portion is slidably connected to the slide rail 34. The pushing structure includes a pushing cylinder 32 (the cylinder barrel of the pushing cylinder 32 is fixedly installed on the bracket 31, and the piston rod is slidably connected to the bracket 31) and a piston rod bracket 331 is integrally formed on the top of the boss portion, and the piston rod of the pushing cylinder 32 is fixedly installed on the piston rod bracket 331.

[0058] During operation, under the push of the cylinder 32, the push plate 33 pushes the profile. When the push plate 33 pushes the profile, the push arm abuts against the profile and pushes the profile onto the push arm clamped on the front push plate 33.

[0059] Example 3

[0060] like Figure 1-5As shown, in this embodiment, based on the structure of embodiment 2, during the forming process, the height of the profile is often different due to the different models. Therefore, in order to ensure that the push arm on the push plate 33 can fully contact the side wall of the profile, for example, for forming with a small height, the height of the push plate 33 is adjusted by lowering it.

[0061] Therefore, the bottom of the bracket 31 is mounted on the frame 1 through a height adjustment structure, and the height of the push plate 33 is adjusted through the height adjustment structure.

[0062] Specifically, the high-adjustment structure includes a pair of high-adjustment screws 311 fixedly installed at the bottom of the bracket 31, the high-adjustment screws 311 being slidably connected to the frame 1; a pair of high-adjustment nuts 3111 positioned at the top and bottom of the frame 1 are threaded onto the high-adjustment screws 311.

[0063] During operation, the height of the push plate 33 is adjusted by synchronously adjusting the height of the two side supports 31. The adjustment method is as follows: loosen the height adjustment nut 3111 until the height adjustment nut 3111 no longer positions the top and bottom of the frame 1, and then adjust the height. Since the length of the height adjustment screw 311 is greater than the height of the frame 1, a certain range of height adjustment can be performed.

[0064] Example 4

[0065] like Figure 1-5 As shown, in this embodiment, based on the structure of embodiment 4, during the profile cutting process, the cutting wheel of the cutting equipment presses against the profile. Although the front and rear side walls of the profile are pressed in the front and rear direction by the push plates 33 on both sides, the end of the profile is subjected to downward cutting force. Therefore, in order to increase the stability of profile cutting and avoid the profile from easily curling up when the cutting wheel presses down to cut the end of the profile (plastic profiles are lightweight and the end is more likely to curl up when pressed down to cut), resulting in changes in posture and affecting the accuracy of cutting.

[0066] The present invention makes the following improvements:

[0067] The push plate 33 is provided with an anti-warping structure 35 to prevent the profile from warping.

[0068] Specifically, height-adjustable anti-tilting structures 35 are respectively assembled and connected to the two push arms of the push plate 33. The anti-tilting structure 35 includes an anti-tilting plate 351, and the push arm has a height adjustment port. The anti-tilting plate 351 is slidably connected to the height adjustment port; the inner end of the anti-tilting plate 351 protrudes from the height adjustment port and is located outside the height adjustment port.

[0069] Meanwhile, the anti-tilting structure 35 also includes an adjusting screw 352 fixedly connected in the height adjustment port, and an anti-tilting plate 351 slidably connected to the adjusting screw 352; a pair of nuts 3521 are threadedly connected to the adjusting screw 352 and positioned at the top and bottom of the anti-tilting plate 351.

[0070] During operation, the relative height of the push plate 33 and the profile is first adjusted according to the method described in the above embodiment, ensuring that the two push arms of the push plate 33 can smoothly contact the side wall of the profile. Then, the height of the anti-tilting plate 351 is adjusted so that the bottom of the anti-tilting plate 351 is flush with the top surface of the profile (the adjustment method is: loosen the pair of nuts 3521 of the positioning anti-tilting plate 351, and then adjust the height. During the adjustment, auxiliary tools such as wrenches can be used for adjustment, and the profile is used as a reference for the height adjustment). That is, when the push cylinder 32 pushes the two push arms of the push plate 33 to contact the side wall of the profile, the bottom of the anti-tilting plate 351 is just slightly contacting the top surface of the profile.

[0071] During the cutting process, the side walls of the profile are clamped and positioned by multiple push plates 33 distributed front and rear. The anti-tilting plates 351 on the push plates 33 lightly abut against the top surface of the profile. Therefore, during the downward cutting process, the profile's posture remains fixed and does not easily tilt due to the limiting and downward pressure effect of the anti-tilting plates 351. Overall, the front and rear side walls of the profile are clamped and positioned by the push plates 33, and the top is positioned by the downward pressure from both sides of the top by the multiple push plates 33. Therefore, this method greatly increases the stability of the profile cutting and improves the cutting accuracy.

[0072] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
