Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of plastic profile turnover racks, in particular to a strip-shaped plastic profile turnover rack. BACKGROUND

[0002] In the field of plastic profile processing technology, strip-shaped plastic profiles such as PVC, ABS, and other materials such as pipes and profiles often need to be turned over on the production line in order to be processed on both sides, detected, or stored.

[0003] The existing turnover racks mostly use simple turnover plate structures, and the working process is usually as follows: after the profile is loaded onto the turnover plate, the turnover plate is rotated by a pneumatic cylinder or manually driven to drop the profile to the designated position.

[0004] However, the existing turnover racks must stop loading during the turnover process and wait for the turnover plate to reset before continuing to load the next profile, which disrupts the production rhythm and cannot meet the needs of high-speed continuous production. At the same time, the profile is prone to deviation or falling on the turnover plate, resulting in inaccurate turnover position and the need for manual intervention to adjust, increasing the operation burden.

[0005] In view of this, we propose a strip-shaped plastic profile turnover rack. SUMMARY

[0006] The purpose of the present application is to provide a strip-shaped plastic profile turnover rack that solves the problems raised in the background art.

[0007] To achieve the above-mentioned purpose, the present application provides the following technical solutions: A strip-shaped plastic profile turnover rack, comprising a rack body, a support fixedly installed on the rack body, a turnover plate provided on the rack body, and a loading mechanism provided on the rack body, wherein a limiting mechanism is provided between the loading mechanism and the turnover plate. The loading mechanism comprises a fixed roller, a rotating roller rotatably installed on the surface of the fixed roller, and a plurality of elastic support rods fixedly installed on the rotating roller.

[0008] Preferably, the loading mechanism further comprises two mounting plates fixedly installed on the support, two mounting racks fixedly installed on both ends of the mounting plate, and a fixed connection between the mounting rack and the fixed roller.

[0009] Preferably, the turnover plate is provided with a plurality of clamping grooves, the elastic support rods are clamped in the clamping grooves, and the plurality of elastic support rods are arrayed.

[0010] Preferably, the elastic support rod comprises a fixed rod fixedly installed on the surface of the rotating roller, and an active rod elastically connected to the fixed rod by a spring.

[0011] Preferably, the fixed roller is fitted with a plurality of torsion springs, the mounting plate is fixedly mounted on the mounting plate, the rotating roller has a notch on its surface, and a pressure plate is provided at the notch position of the rotating roller.

[0012] Preferably, the fixing plate abuts against the lower end of the torsion spring, and the pressure plate presses against the upper end of the torsion spring.

[0013] Preferably, the limiting mechanism includes a sliding groove, which is formed on the mounting frame. A limiting rod is slidably installed in the sliding groove, and a spring is provided between the limiting rod and the sliding groove.

[0014] Preferably, the flip plate and the frame are connected by a cylinder, and the flip plate and the limiting rod are connected by magnetic force.

[0015] Preferably, a limiting block is fixedly installed on the limiting rod, and the limiting block is inserted into the fixed roller and the rotating roller.

[0016] Preferably, the bracket is provided with mounting bolts, the bracket is equipped with a stop bar by the mounting bolts, the frame includes a base, the base is provided with a turning edge, and a turning pad is fixedly installed on the base.

[0017] By employing the above technical solution, the present invention provides a strip-shaped plastic profile turning rack that has at least the following beneficial effects: (1) This invention, by setting a loading mechanism and a limiting mechanism on the frame in conjunction with a flipping plate, allows the limiting mechanism to release the loading mechanism when the flipping plate is in operation, thus enabling the profile to smoothly transition from the loading mechanism to the flipping plate. The loading mechanism can quickly reset and limit itself after the flipping plate is disengaged, thereby supporting the profile. This allows the loading mechanism to continue supporting new profiles for loading during the flipping process, avoiding production interruptions, ensuring production continuity, and thus meeting the needs of high-speed continuous production.

[0018] (2) By setting up elastic support rods, movable rods and fixed rods, the present invention can automatically adjust the opening size according to the self-weight of the profile, and adapt to various cross-section profiles such as round and rectangular. This can effectively improve the applicability of the flipping frame and avoid the profile being crushed or scratched due to the rigid clamping of the elastic support rods. At the same time, when the profile is transitioned to the flipping plate, it can be placed on the center line of the flipping plate, thereby effectively enhancing the accuracy and stability of the flipping and reducing the frequency of manual intervention.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-8 , a turning rack for strip plastic profiles, including a frame body 1, and the frame body 1 provides support, turning angle and storage after turning for the turning of plastic profiles. The frame body 1 includes a base 11, the top of the base 11 is a "U" - shaped structure with an upward opening, and one side is an inclined turning edge 12, and a turning pad 13 is fixedly installed on the base 11. The inclined turning edge 12 can assist the strip plastic profiles in turning, and the turning pad 13 can play a buffering role.

[0023] Please refer to Figure 2A bracket 2 is fixedly installed on the frame 1. Two stop bars 4 are installed on the bracket 2 by mounting bolts 3. The stop bars 4 serve as limiters to prevent the profiles from deviating when they are conveyed onto the turning rack. A turning plate 5 is connected to the frame 1 by a cylinder. The turning plate 5 contacts the bottom end of the stop bars 4. The turning plate 5 is used to place the profiles. The turning plate 5 and the cylinder are rotatably connected, so that the cylinder can drive the turning plate 5 to move up and down without hindering the turning plate 5 from rotating along the turning edge 12 to turn the profiles.

[0024] Please see Figure 1 The frame 1 is equipped with a loading mechanism 6, which can continue to support and feed new profiles when the flipping plate 5 is working, thereby enhancing the continuity of profile flipping operations without waiting for the flipping plate 5 to reset.

[0025] Please see Figure 3 The loading mechanism 6 includes two mounting plates 62, which are fixedly mounted on the bracket 2. Mounting frames 63 are fixedly mounted at both ends of each mounting plate 62, forming a downward-opening "U"-shaped structure between the mounting plates 62 and the mounting frames 63, providing a stable platform for the installation of other structures. A fixed roller 64 is fixedly mounted between the two mounting frames 63, and a rotating roller 65 is rotatably mounted on the surface of the fixed roller 64. Multiple elastic support rods 66 are fixedly mounted on the rotating roller 65. The elastic support rods 66 provide support for the profile. The multiple elastic support rods 66 are arranged in an array, ensuring uniform and stable force distribution when supporting the profile. Furthermore, elastic support rods 66 are fixedly mounted on the rotating rollers 65 on both mounting plates 62, resulting in two sets of elastic support rods 66 in contact, preventing jamming of the profile during loading.

[0026] Furthermore, the rotating roller 65 can rotate along the fixed roller 64. The rotation of the rotating roller 65 can drive the elastic support rod 66 to rotate, thereby causing the two sets of elastic support rods 66 to open and close, thus realizing the functions of unloading flipping and loading support respectively. When the elastic support rod 66 is open, it forms a "V"-shaped opening, allowing the profile to automatically move along the "V"-shaped opening of the elastic support rod 66 under the action of gravity. The center of the "V"-shaped opening is on the center line of the flipping plate 5, so that when the profile is transferred to the flipping plate 5, it automatically falls on the center line of the flipping plate 5.

[0027] Please see Figure 6The elastic support rod 66 includes a fixed rod 661, which is fixedly mounted on the surface of the rotating roller 65. A movable rod 662 is elastically connected to the fixed rod 661 via a spring. The movable rod 662 can move within a certain range along the fixed rod 661. The spring provides elastic force to the movable rod 662, keeping it stable. This allows the elastic support rod 66 to adapt to different profiles for material cutting when rotated open. At a fixed rotation angle, the displacement of the movable rod 662 can increase the distance between the two movable rods 662, thereby adapting to the cutting of profiles of different sizes.

[0028] Specifically, after the elastic support rod 66 rotates at a certain angle, the contact between the profile and the movable rod 662 changes from perpendicular to an angled contact. Under the weight of the profile, the movable rod 662 is pushed towards the interior of the fixed rod 661, thereby increasing the opening between the two sets of elastic support rods 66. This allows the profile to be transferred to the flip plate 5 more quickly and enables the cutting of larger profiles, improving applicability. One end of the movable rod 662 is a hemispherical structure made of an elastic material, such as rubber. The hemispherical structure prevents the movable rod 662 from scratching the profile, and the elastic material and spring prevent the movable rod 662 from making hard contact with the profile, which could damage it.

[0029] Please see Figure 4 A plurality of torsion springs 69 are fitted onto the surface of the fixed roller 64, and a notch is provided on the surface of the rotating roller 65, with the torsion springs 69 located at the notch. The notch limits the torsion springs 69, thus fixing them to the surface of the fixed roller 64. A fixing plate 68 is fixedly mounted on the mounting plate 62, and a pressure plate 67 is provided at the notch of the rotating roller 65. The fixing plate 68 abuts against the lower end of the torsion spring 69, and the pressure plate 67 presses against the upper end of the torsion spring 69. The pressure plate 67 and the fixing plate 68 limit the rotation of the torsion spring 69, preventing it from rotating along the surface of the fixed roller 64. At the same time, the pressure plate 67 can compress the torsion spring 69 when the rotating roller 65 rotates, and after rotation stops, the torsion spring 69 provides elastic force for the pressure plate 67 and the rotating roller 65 to return to their original positions.

[0030] Please see Figure 5 Multiple torsion springs 69 are arranged in an array, which makes the overall rebound force of the rotating roller 65 uniform when it rotates. At the same time, it enhances the overall anti-interference ability. The damage or failure of a single torsion spring 69 will not affect the operation of the rotating roller 65, thus enhancing the anti-interference ability and service life of the rotating roller 65. In addition, the rotational rebound force of the rotating roller 65 can be adjusted by adding or removing torsion springs 69, thereby enhancing its applicability to profiles of different qualities.

[0031] It is worth noting that the pressure plate 67 contacts the bottom end of the mounting plate 62, and the mounting plate 62 limits the rotation angle of the pressure plate 67. This ensures that, under the elastic force of the torsion spring 69 and the limiting effect of the mounting plate 62, the pressure plate 67 and the mounting plate 62 are in close contact. At this time, the elastic support rod 66 is in a horizontal state. The pressure plate 67 can prevent the elastic support rod 66 from tilting upwards, making the reset of the elastic support rod 66 faster and more stable.

[0032] Please see Figure 7 It should be noted that the flip plate 5 has multiple slots 61, and the elastic support rod 66 is engaged in the slots 61, so that the elastic support rod 66 will not affect the loading and unloading of the flip plate 5.

[0033] Please see Figure 7 A limiting mechanism 7 is provided between the loading mechanism 6 and the tilting plate 5. It is used to limit the elastic support rod 66 when the tilting plate 5 is working, so that the elastic support rod 66 can support the material loading.

[0034] Please see Figure 8 The limiting mechanism 7 includes a sliding groove 73, which is formed on the mounting bracket 63. A limiting rod 71 is slidably installed in the sliding groove 73, and a spring is provided between the limiting rod 71 and the sliding groove 73. The spring provides a constant upward elastic force to the limiting rod 71, causing the limiting rod 71 to be subjected to an upward displacement force along the sliding groove 73. A limiting block 72 is fixedly installed on the limiting rod 71. The limiting block 72 is inserted into the fixed roller 64 and the rotating roller 65. The insertion of the limiting block 72 into the fixed roller 64 and the rotating roller 65 can limit the rotation of the rotating roller 65, preventing the rotating roller 65 from rotating. It should be noted that when the limiting block 72 is inserted, the elastic support rod 66 on the rotating roller 65 is in a horizontal state, thereby making the two sets of elastic support rods 66 in a closed state, which can provide support for the profile sample.

[0035] It is worth noting that the flipping plate 5 and the limiting rod 71 are connected by magnetic force. This is achieved through a permanent magnet, allowing the limiting rod 71 to move downwards synchronously when the flipping plate 5 moves downwards. The downward movement of the limiting rod 71 causes the limiting block 72 to disengage from the rotating roller 65, releasing the limiting position of the rotating roller 65 and not affecting the material feeding. Simultaneously, the displacement distance of the limiting rod 71 is limited by the sliding groove 73. When the flipping plate 5 disengages from the limiting rod 71, the limiting rod 71 moves upwards along the sliding groove 73 to reset under the action of a spring.

[0036] A strip-shaped plastic profile flipping rack, the working principle of which is as follows: The profile is fed along the stop bar 4 and the flip plate 5. After feeding, the cylinder is activated, causing the flip plate 5 to move downwards. As the flip plate 5 moves downwards, the limiting rod 71 moves downwards synchronously via magnetic force. The downward movement of the limiting rod 71 causes the limiting block 72 to disengage from the rotating roller 65, releasing the limiting position of the rotating roller 65. Under its own weight, the profile compresses the elastic support rod 66, causing the elastic support rod 66 to drive the rotating roller 65 to rotate along the fixed roller 64. After rotating a certain angle, the profile, under its own weight, can compress the movable rod 662, causing the movable rod 662 to move along the fixed rod 661. This widens the opening between the two sets of movable rods 662, allowing the profile to detach from the elastic support rod 66 and fully enter the flip plate 5. Furthermore, the limiting and conveying effect of the two sets of elastic support rods 66 keeps the profile positioned at the center line of the flip plate 5, thereby improving the stability of the profile during each flipping.

[0037] As the flipping plate 5 continues to move downwards, it contacts the flipping edge 12 and flips at an angle. Under the action of gravity, the profile flips along the flipping plate 5 and enters the base 11. During the flipping, it is cushioned by the flipping pad 13 to prevent hard contact that could damage the profile. This completes one flipping operation of the profile.

[0038] As the flip plate 5 continues to move downwards, the displacement distance of the limiting rod 71 is limited by the sliding groove 73. When the flip plate 5 disengages from the limiting rod 71, the limiting rod 71 moves upwards along the sliding groove 73 under the action of the spring force to reset. Because the pressure plate 67 exerts a squeezing effect on the torsion spring 69 when the rotating roller 65 rotates along the fixed roller 64, after the profile disengages from the elastic support rod 66, the rotating roller 65 is subjected to the restoring force of the torsion spring 69, causing the rotating roller 65 to rotate and reset along the fixed roller 64. During reset, the torsion spring 69 drives the rotating roller 65 to rotate, causing the pressure plate 67 to quickly abut against the mounting plate 62, achieving rapid and precise reset of the rotating roller 65. The reset of the limiting rod 71 allows the limiting block 72 to be re-inserted onto the rotating roller 65 and the fixed roller 64 to limit the rotation roller 65, thereby allowing the elastic support rod 66 to support the profile feeding.

[0039] After the flipping plate 5 finishes flipping the material, it resets under the operation of the air spring. The slot 61 of the flipping plate 5 is re-engaged on the elastic support rod 66 to support the profile. Repeating the above steps can achieve uninterrupted flipping of the profile.
