Description

Technical Field

[0001] This utility model relates to the technical field of mechanical equipment, specifically to a tearing machine for connecting strips of linear light fixtures. Background Technology

[0002] Currently, in the linear lighting market, due to the influence of profile blank forming, "H" or "U" shaped profiles used in linear lighting structures deform when the cantilever length is large, especially when far from the central rib. The longer the cantilever, the more severe the deformation, thus affecting product quality and efficiency. Taking an "H" shaped profile as an example, the profile has a central rib. The profile near the rib is less prone to deformation, but when it is far from the central rib, the profile will deform, resulting in undesirable conditions such as uneven or open ends. Therefore, to solve this problem during profile blank manufacturing, a connecting piece (such as...) is added at the cantilever. Figure 4 As shown in the image, this design prevents the opening size of the profile from deforming due to external forces during the blank pulling process. However, when the profile is needed, the challenge arises in removing the newly added connecting pieces.

[0003] Currently, the removal of connecting plates added to the cantilever of profiles is done manually using tools such as pliers and wrenches. This method is inefficient and can damage the profile if not handled carefully, leading to deformation or scratches on the profile surface. Therefore, for profiles with long cantilevered sections and added connecting plates, a tearing device is needed that can quickly and easily peel off the connecting plates, thereby achieving efficient and stable tearing operations.

[0004] In order to solve one or more technical problems existing in the prior art, the purpose of this application is to provide a tearing machine for connecting strips of linear light profiles, which effectively solves the problems of tedious manual tearing of profiles, high labor intensity caused by repetitive operations, and easy deformation or damage to profiles. The tearing process of connecting strips is simple, the tearing operation of profile connecting strips is efficient, and the quality and integrity of the profiles are guaranteed.

[0005] To solve the aforementioned technical problems, this application adopts the following technical solution:

[0006] A tearing machine for connecting strips of linear light fixtures includes a frame, several fixed supports mounted on the frame, a mounting base fixed on the fixed supports, a lateral moving mechanism located below the mounting base, a tearing wheel located below the lateral moving mechanism, and a limiting mechanism located on the frame.

One end of the lead screw is connected to the stepper motor, the slide is threaded to the lead screw and slidably connected to the guide rail, the lead screw rotates forward and backward via the stepper motor, and the tearing wheel is mounted on the slide.

[0009] Preferably, the travel sensing switch is a photoelectric switch.

[0010] Preferably, a sliding groove is provided on one side of the mounting base, and an adjusting slider is provided in the sliding groove. The travel sensor switch is located on the adjusting slider, and the travel sensor switch slides relative to the adjusting slider.

[0011] Preferably, the limiting mechanism includes several baffles and clamping members disposed on the frame, and at least one end baffle adopts an L-shaped structure, and the profile is clamped and fixed on the frame by the baffles and the clamping members.

[0012] Preferably, two baffles are used and located at both ends of the profile to be fixed. Both baffles have an L-shaped structure, and the distance between the two end faces of the two baffles is greater than the length of the profile to be fixed.

[0013] Preferably, the frame is provided with two parallel adjustment slots, and the baffle is fixed in the adjustment slot by bolts; the distance between two adjacent baffles can be adjusted by the adjustment slots.

[0015] Preferably, the width of the tearing wheel is 3-5 mm narrower than the connecting piece to be peeled.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] When it is necessary to peel off the connecting pieces inside the profile, simply adjust the equipment according to the size of the core material, and the tearing wheel on the equipment can quickly tear and peel off the connecting pieces. The entire peeling process starts from one end of the connecting piece, and the shearing force generated by the height difference between the tearing wheel and the connecting piece of the profile cantilever gradually tears and separates them.

Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0027] like Figures 1-4 As shown, a strip light profile connecting piece tearing machine includes a frame 1, several fixed supports 4 on the frame 1, a mounting base 5 fixed on the fixed supports 4, a lateral moving mechanism 8 below the mounting base 5, a tearing wheel 6 below the lateral moving mechanism 8, and a limiting mechanism 2 on the frame 1. The tearing wheel 6 moves left and right along the mounting base 5 via the lateral moving mechanism 8. A limit sensor switch 9 is also provided on one side of the mounting base 5. The tearing wheel 6 is an H-shaped nylon roller. The profile with the detachable connecting piece is mounted on the frame 1 via the limiting mechanism 2. The tearing wheel 6 and the cut surface of the detachable connecting piece are staggered. The connecting piece on the profile cantilever is torn from one end by the pressure of the tearing wheel 6 until the entire piece is peeled off.

[0028] The method for peeling off the connecting piece using the strip light profile connecting piece tearing machine includes:

[0029] S1. Adjust the position of the baffle 22 according to the different lengths of the profile 20;

[0030] S2. Replace the tearing wheel 6 with the corresponding width according to the different profile 20 cantilever opening width and connecting piece 30 width;

[0031] S3. Depending on the different heights of the profile 20, select whether to add a base plate of corresponding thickness to the frame 1 so that when the connecting piece 30 is disassembled, the tearing wheel 6 and the connecting piece 30 of the cantilever of the profile 20 can form a height difference.

[0032] S4. Attach one end and one side of the profile 20 with connecting piece 30 to each of the baffles 22, and then press and fix it by clamping member 21 so that the open end of the cantilever faces upward and the outer side of the connecting piece 30 is located directly below the tearing wheel 6.

[0033] S5. Adjust the positions of the two limit sensor switches 9 so that the starting and stopping ends of the tearing wheel 6 are located on the outer sides of both ends of the profile 20.

[0034] S6. Power the controller 82 by starting the switching power supply, set the parameters through the control panel, control the stepper motor 83 to rotate forward and backward by starting the driver 81, drive the lead screw 86 to rotate forward and backward by the forward and backward rotation of the stepper motor 83, and the slide 84 of the lead screw 86 moves left and right along the guide rail 85, thereby driving the tearing wheel 6 to move.

[0035] S7. Due to the height difference between the tearing wheel 6 and the connecting piece 30 of the cantilever of the profile 20, the tearing wheel 6 gradually contacts one end of the connecting piece 30 as it moves. The tearing wheel 6 presses the connecting piece 30 downward, causing the connecting piece 30 to gradually tear and separate from both sides of the profile 20 starting from the contact area at one end. This process continues until the tearing wheel 6 passes the entire connecting piece 30, squeezing and peeling the connecting piece 30 from the cantilever of the profile 20, thus achieving the tearing and peeling function.

[0036] In actual operation, the linear light profile with connecting pieces is placed on the frame 1 and quickly positioned by the limiting mechanism 2. Then, the tearing wheel 6 is moved along the length of the connecting piece by the lateral moving mechanism 8. The height difference between the tearing wheel 6 and the connecting piece causes misalignment and extrusion tearing, so that the two sides of the connecting piece gradually tear and separate from the profile from one end, achieving overall peeling. The tearing wheel 6 is an H-shaped nylon roller, which avoids scratching the profile surface, ensures quiet operation during rolling, reduces the force area, and maximizes shearing force. A rolling shaft and bearing in the middle ensure smooth and non-jamming rolling. The stop of the servo motor is automatically determined by the travel sensor switch 9. When started, the slide 84 automatically stops when it slides to the travel sensor switch 9. When started again, it stops again after moving to another travel sensor switch 9. During operation, simply pressing the start button automatically starts the operation, eliminating the need for manual stopping. Furthermore, peeling can be performed in both a single round trip, resulting in higher efficiency.

[0037] When it is necessary to peel off the connecting pieces 30 within different profiles 20, simply adjust the equipment according to the core material dimensions. The tearing wheel 6 on the equipment can then quickly tear and peel off the connecting pieces 30. The peeling process starts from one end of the connecting piece 30, and the shearing force generated by the height difference between the tearing wheel 6 and the connecting piece 30 on the cantilever of the profile 20 gradually tears and separates them. This effectively avoids deformation of the cantilever due to impact during hammering, ensuring that the opening size of the profile 20 does not deform due to external forces during blank pulling. Simultaneously, the automated operation effectively solves the problems of tedious manual profile tearing, high labor intensity from repetitive operations, and the risk of profile deformation or damage. The tearing process for the connecting pieces 30 is simple, the efficiency of profile connecting piece tearing is high, the quality and integrity of the profile are maintained, the operation is simple, the application range is wide, and the peeling efficiency for connecting pieces within a uniform batch of profiles is high.

[0038] A further improvement is that the fixed bracket 4 adopts an L-shaped structure, the mounting base 5 is suspended and fixed on the fixed bracket 4, and the lateral moving mechanism 8 installed on the mounting base 5 is arranged downwards.

[0039] The fixed bracket 4 adopts an L-shaped structure. The height of the L-shaped fixed bracket 4 cannot be adjusted and is always a uniform height. By placing a base plate of corresponding thickness on the frame 1, the height difference between the tearing wheel 6 and the connecting piece at the cantilever of the profile can be used to achieve tear height adaptability and functional compatibility of tearing for different profiles by replacing the corresponding tearing wheel 6 and the base plate of corresponding thickness on the frame 1 according to the height and opening width of different profiles.

[0040] A further improvement is made to the lateral movement mechanism 8, which includes a controller 82 mounted on the frame 1, a switching power supply mounted on the controller 82, a driver 81 with a control panel mounted inside the controller 82, a stepper motor 83 driven by the controller 82 at one end of the mounting base 5, a lead screw 86 and a guide rail 85 mounted below the mounting base 5, and a slide block 84 mounted on the lead screw 86 and the guide rail 85. One end of the lead screw 86 is connected to the stepper motor 83, the slide block 84 is threadedly connected to the lead screw 86 and slidably connected to the guide rail 85, the lead screw 86 rotates forward and backward via the stepper motor 83, and the tearing wheel 6 is mounted on the slide block 84.

[0041] One end of the lead screw 86 is connected to the stepper motor 83, and the slide 84 is threadedly connected to the lead screw 86 and slidably connected to two guide rails 85. The lead screw 86 rotates forward and backward via the stepper motor 83, and the tearing wheel 6 is mounted on the slide 84. A switching power supply converts AC power to DC power to supply the driver 81 and controller 82. The driver 81 then sets parameters via the operation panel on the controller 82 to control the forward and reverse rotation of the stepper motor 83. The stepper motor 83 is connected to the lead screw 86 via a linkage shaft. The forward and reverse rotation of the stepper motor 83 causes the lead screw 86 to rotate forward and backward via the linkage shaft. The slide 84 on the lead screw 86 contains ball bearings that mate with the lead screw 86 and a guide groove for the lead screw 86. Based on the forward and reverse rotation of the lead screw 86, the slide 84 moves forward and backward along the guide rails 85. During the linear motion of the lead screw 86 in both forward and reverse rotation, the tearing wheel 6 presses down on the connecting piece of the profile, squeezing and peeling it off, thus achieving the tearing and peeling function.

[0042] A further improvement is made in that the travel sensing switch 9 is a photoelectric switch.

[0043] The limit switch 9 adopts a photoelectric switch, which is small in size, multifunctional, highly accurate, has a long detection distance, good anti-light effect, short response time, strong anti-interference ability and long service life.

[0044] A further improvement is that a sliding groove 11 is provided on one side of the mounting base 5, and an adjusting slider 10 is provided in the sliding groove 11. The travel sensing switch 9 is provided on the adjusting slider 10, and the travel sensing switch 9 slides relative to the adjusting slider 10.

[0045] The relative position of the travel sensor switch 9 can be adjusted by adjusting the slider 10, so that the travel sensor switch 9 can be adjusted according to different connecting piece lengths, so that the tearing wheel 6 can peel off the connecting piece with the shortest travel.

[0046] A further improvement based on any of the above schemes is that the limiting mechanism 2 includes a plurality of baffles 22 and clamping members 21 provided on the frame 1, at least one end baffle 22 adopts an L-shaped structure, and the profile is clamped and fixed on the frame 1 by the baffles 22 and the clamping members 21.

[0047] The limiting mechanism 2 consists of several baffles 22 and clamping parts 21 installed on the frame 1. The baffles 22 can limit the side of the profile, so that the fixed profile is parallel to the lead screw 86 and avoids misalignment when the connecting piece is peeled off. The clamping parts 21 can press and fix it, which can avoid loosening during manual operation and make the stability better during the peeling of the connecting piece. Generally, the clamping parts 21 are push-pull quick clamps, which can be fixed on the frame 1 with screws, making operation more convenient.

[0048] A further improvement is made in that two baffles 22 are used and located at both ends of the profile to be fixed. Both baffles 22 adopt an L-shaped structure, and the distance between the two end faces of the two baffles 22 is greater than the length of the profile to be fixed.

[0049] Two baffles 22 are used and located at both ends of the profile to be fixed. This ensures the parallelism of the profile after installation with minimal effort, preventing tilting. Both baffles 22 have an L-shaped structure, and the distance between their end faces is greater than the length of the profile to be fixed. When installing the profile, simply attach one side of both baffles 22 and then press one end of the profile against the side of either baffle 22 to achieve precise positioning. This makes operation more convenient, easier, and ensures higher parallelism. Especially when used with two limit switches 9, during operation, when one end of the profile is attached to the baffle 22 near the tearing wheel 6, it effectively ensures peeling while minimizing the travel distance.

[0050] A further improvement is made in that two parallel adjustment slots 3 are provided on the frame 1, and the baffle 22 is fixed in the adjustment slots 3 by bolts; the distance between two adjacent baffles 22 can be adjusted by the adjustment slots 3.

[0051] Since the linear lights are of the same length as the profiles, the length of the profiles that need to be stripped is also different. Therefore, in order to facilitate the adjustment of the position of the baffle 22, two parallel adjustment slots 3 are machined in the frame 1, so that the baffle 22 can be fixed to the adjustment slots 3 by bolts. The baffle 22 can be adjusted or added or removed at any position according to the different lengths of the linear lights, making the installation of the baffle 22 more flexible.

[0052] A further improvement is that the bottom of the slide block 84 is provided with a U-shaped sheet metal part 7, and the tearing wheel 6 is mounted on the U-shaped sheet metal part 7 through a rotating shaft. The tearing wheel 6 can be disassembled and replaced through the U-shaped sheet metal part 7.

[0053] The tearing wheel 6 is mounted on the slide block 84 via a U-shaped sheet metal part 7. When it needs to be replaced, it can be directly replaced by disassembling and assembling the U-shaped sheet metal part 7, which is easier to operate and has a wider range of applications. It can peel off the connecting pieces of different profiles by replacing the tearing wheel 6. When peeling off the connecting pieces on the profile, if the height changes due to profile replacement, it is usually done by adding a base plate to raise the surface of the frame 1 before installation and fixation. However, when there are many differences in product height, a large amount of spare base plates are required, and the length and flatness of the base plates are required, which can easily increase storage and inventory costs. However, the U-shaped sheet metal part 7 and the slide block 84 have surface contact. The distance between the tearing wheel 6 and the connecting piece can be adjusted by adding shims, effectively avoiding the material and flatness problems caused by raising the entire support surface when adjusting the height between the tearing wheel 6 and the connecting piece.

[0054] A further improvement is that the width of the tearing wheel 6 is 3-5mm narrower than the connecting piece to be peeled.

[0055] The tearing wheel 6 is about 3-5mm narrower than the connecting piece, which allows the tearing wheel 6 to form a shearing force as much as possible, thus facilitating better peeling of the connecting piece.

[0056] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
