Description

Technical Field

[0001] The present invention relates to a hose reel, and more particularly to an adjusting mechanism of a hose reel. Background Art

[0002] Currently, hose reels are widely used in fields such as industrial fluid transfer, cable management, and fire protection systems. In order to achieve automatic and orderly storage of pipelines, a pipeline adjusting mechanism is often provided in the hose reel, so that the pipeline to be wound can be evenly arranged in the axial direction of the reel during the winding process, thereby improving the winding efficiency and neatness, and avoiding local stacking or pulling. However, in actual use, due to differences in the types and diameters of the pipelines used, traditional adjusting mechanisms are difficult to adapt to multiple specifications of pipelines at the same time. Especially in scenarios where long-distance reciprocating guiding is required, the limitations of the existing technology are more obvious.

[0003] Currently, common technical solutions mostly adopt a pair of upper and lower guide wheels. The pipeline passes through the wire outlet cavity between the guide wheels, and the distance between the upper and lower guide wheels is adjusted to adapt to pipelines of different diameters. Although such a structure can achieve preliminary limiting of the pipeline in a static state, during the process where the entire guiding mechanism needs to move reciprocally along the axial direction following the servo drive mechanism, since the contact between the guide wheel and the pipeline is usually a line contact, when the servo drive mechanism drives the guiding structure to move left and right, due to insufficient friction between the guide wheel and the pipeline, slipping is very likely to occur, and the pipeline cannot be effectively driven to the desired position. Especially when the pipeline itself is light in weight or has a smooth surface, the reciprocating movement of the guiding structure cannot even form a traction effect on the pipeline, ultimately resulting in the inability to achieve uniform and orderly winding of the pipeline.

[0004] To solve the above problems, some solutions attempt to adapt to pipelines of different diameters by replacing different types of guide wheel structures. However, this method not only increases the workload of assembly and debugging, but also is extremely inconvenient to operate when frequently changing the types of pipelines, reducing production efficiency, and is not suitable for application scenarios with multiple specifications and frequent replacements.

[0005] In summary, there is still much room for improvement in the adaptability, guiding stability, and operation convenience of the existing hose reel adjusting mechanism. There is an urgent need for a hose reel adjusting mechanism structure that can automatically adjust the clamping state according to the weight and pulling force of the pipeline, improve the guiding friction, adapt to pipelines of different diameters, and reduce slipping, so as to improve the guiding accuracy and stability during the pipeline winding process and achieve truly efficient and uniform winding. Summary of the Invention

[0006] To solve the above problems, the present invention provides an adjustment mechanism for a reel, which realizes the active clamping of a flexible guide wheel by utilizing the weight of the pipeline and the pulling force, effectively increases the contact pressing force between the guide wheel and the pipeline, significantly reduces the winding deviation problem caused by slipping during the adjustment process, and effectively solves the deficiencies in the prior art.

[0007] The present invention is realized through the following technical solutions: An adjustment mechanism for a reel, comprising:

[0008] A pipeline adjustment mechanism, the pipeline to be wound reciprocates through the pipeline adjustment mechanism and is wound on a reel;

[0009] A servo drive mechanism, the pipeline adjustment mechanism is installed on the servo drive mechanism and reciprocates through the servo drive mechanism;

[0010] The pipeline adjustment mechanism includes a first support rod and a second support rod that are symmetric left and right. The first support rod and the second support rod on each side cross and are hinged in a cross shape, and both ends of the symmetric first support rod and the second support rod are connected by a connecting shaft;

[0011] One end of the two first support rods is provided with a first flexible guide wheel, and the other end of the two first support rods is provided with an auxiliary wheel;

[0012] One end of the two second support rods is provided with a second flexible guide wheel, and the other end of the two second support rods is provided with a load-bearing wheel;

[0013] A wire outlet cavity is formed between the first flexible guide wheel and the second flexible guide wheel. The pipeline to be wound passes through the wire outlet cavity, winds around the top of the load-bearing wheel, and then winds on the reel. The weight and pulling force of the pipeline are used to press down the load-bearing wheel;

[0014] An axial extrusion mechanism is installed on both sides of the second flexible guide wheel. When the load-bearing wheel is pressed down, the axial extrusion mechanism extrudes both sides of the second flexible guide wheel, thereby reducing the pipeline spacing between the second flexible guide wheels.

[0015] As a preferred technical solution, the core extrusion mechanism includes rotating disks arranged on both sides of the second flexible guide wheel, and the rotating disks are rotatably connected to the second flexible guide wheel;

[0016] An extrusion disk is arranged at the outer end of the rotating disk, and a plurality of protruding extrusion parts are arranged on the side of the extrusion disk facing the rotating disk;

[0017] The extrusion bushing is installed at the outer end of the extrusion disc and sleeved on the connecting shaft. The extrusion bushing can rotate circumferentially relative to the connecting shaft. The extrusion bushing is driven by a pulling drive mechanism. An assembly hole is provided in the middle of the extrusion bushing, and the connecting shaft passes through the assembly hole.

[0018] As a preferred technical solution, the extrusion bushing includes a threaded connection section, an extrusion section, and a gear transmission section. A connecting shaft hole is provided on the second support rod, and an internal threaded section is provided on the inner wall of the connecting shaft hole. The extrusion bushing is threadedly connected to the internal threaded section through the threaded connection section. The gear transmission section is located in the connecting shaft hole. The extrusion section is in contact with the end face of the extrusion disc, and the pulling drive mechanism is in gear engagement with the gear transmission section.

[0019] As a preferred technical solution, the pulling drive mechanism includes a pulling rack and a pulling wire. One end of the pulling wire is connected to the pulling rack, and the other end of the pulling wire is connected to the load-bearing pulling section of the second support rod.

[0020] As a preferred technical solution, the pulling rack is installed in a rack installation groove inside the second support rod. The rack installation groove communicates with the connecting shaft hole. A part of the pulling rack is located in the connecting shaft hole and is in gear engagement with the gear transmission section. When the pulling wire pulls the pulling rack, the extrusion bushing is driven to rotate threadedly by the pulling rack, thereby extruding the extrusion disc.

[0021] As a preferred technical solution, an elastic pressing mechanism is provided on one side between the first support rod and the second support rod. Through the elastic pressing mechanism, the first flexible guide wheel and the second flexible guide wheel are always in guiding contact with the pipeline to be wound.

[0022] As a preferred technical solution, the elastic pressing mechanism includes a fixed step and a tension spring. The fixed steps are respectively fixedly installed on the first support rod and the second support rod. Both sides of the tension spring are fixedly connected to the fixed steps, and the first support rod and the second support rod are tightened by the tension spring.

[0023] As a preferred technical solution, the load-bearing pulling section is elastically hinged to the second support rod.

[0024] As a preferred technical solution, a screw rod connection frame is fixedly provided at the top of the two first support rods. The screw rod connection member is connected to the servo drive mechanism, and the screw rod connection member is driven to reciprocate by the transmission screw rod in the servo drive mechanism.

[0025] As a preferred technical solution, a guiding bracket is fixedly arranged at the bottom of the two second support rods. A guiding groove is arranged at the bottom of the guiding bracket. The guiding bracket is guidingly installed on a guiding rod, and the guiding groove is guidingly connected with the guiding rod.

[0026] The beneficial effects of the present invention are as follows: For the adjusting mechanism of a reel provided by the present invention, the weight of the pipeline itself and the pulling force generated during the winding process act on the load-bearing wheel arranged at the end of the adjusting mechanism, thereby driving the axially squeezing mechanism linked thereto, causing elastic deformation of the two side end faces of the second flexible guiding wheel towards the direction of the pipeline and achieving effective clamping. Thus, during the left-right reciprocating axial movement of the guiding mechanism, the friction force between the guiding wheel and the pipeline is significantly increased, effectively preventing the pipeline from slipping, ensuring that the pipeline can move synchronously with the adjusting mechanism, and achieving a more accurate and uniform winding effect.

[0036] All features disclosed in this specification, or all steps in the disclosed methods or processes, except for mutually exclusive features and / or steps, can be combined in any manner.

[0037] Any feature disclosed in this specification (including any additional claims, abstract, and drawings), unless specifically stated, can be replaced by other equivalent or similar-purpose alternative features. That is, unless specifically stated, each feature is only an example of a series of equivalent or similar features.

[0038] As Figure 1 As shown, an adjustment mechanism of a pipe coiler of the present invention includes a pipeline adjustment mechanism. The pipeline 100 to be wound reciprocates through the pipeline adjustment mechanism and is wound on a reel. The pipeline is evenly wound on the reel through the pipeline adjustment mechanism;

[0039] It further includes a servo drive mechanism. The pipeline adjustment mechanism is installed on the servo drive mechanism and reciprocates through the servo drive mechanism. The servo drive mechanism includes a lead screw transmission pair 1 and a servo motor 2. Among them, the lead screw transmission pair 1 can adopt a double-pitch lead screw to enable it to move left and right reciprocally;

[0040] The pipeline adjustment mechanism includes a first support rod 13 and a second support rod 10 that are symmetric left and right. The first support rod 13 on each side crosses and is hinged with the second support rod 10. Both ends of the symmetric first support rod 13 and the second support rod 10 are connected by a connecting shaft 17. The first support rod 13 and the second support rod 10 arranged crosswise are in an "X" shape;

[0041] Among them, one end of the two first support rods 13 is provided with a first flexible guide wheel 6, and the other end of the two first support rods 13 is provided with an auxiliary wheel 14;

[0042] One end of each of the two second support rods 10 is equipped with a second flexible guide wheel 8, and the other end of each of the two second support rods 10 is equipped with a load-bearing wheel 4. The linkage between the first support rods 13 and the second support rods 10 on both sides is realized through a connecting shaft 17. Therefore, the connection positions of the traditional shaft with the first flexible guide wheel 6, the auxiliary wheel 14, and the load-bearing wheel 4 can be connected by bearing rolling. At the position of the second flexible guide wheel 8, since an extrusion bushing 18 (the structure of the extrusion bushing 18 will be described in detail later) is provided, bearings can be not provided;

[0043] The materials of the first flexible guide wheel 6 and the second flexible guide wheel 8 can both adopt flexible rubber materials. The auxiliary wheel 14 can be provided or not provided in this embodiment.

[0044] Among them, an outlet cavity is formed between the first flexible guide wheel 6 and the second flexible guide wheel 8. The pipeline to be wound passes through the outlet cavity and then winds around the top of the load-bearing wheel 4 and is wound on the winding wheel. The weight and pulling force of the pipeline press down the load-bearing wheel 4, as Figure 4 shown;

[0045] It further includes an axial extrusion mechanism 9, which is installed on both sides of the second flexible guide wheel 8. When the load-bearing wheel 4 is pressed down, the axial extrusion mechanism 9 extrudes both sides of the second flexible guide wheel 8, thereby reducing the pipeline spacing between the second flexible guide wheels 8. When the axial extrusion mechanism 9 applies an end face pressure, both sides of the second flexible guide wheel 8 will clamp the pipeline in the middle, so that when moving axially left and right, it can drive the pipeline to perform an axial reciprocating winding action and reduce the slipping situation.

[0046] Among them, the shaft core extrusion mechanism includes rotating disks 20 provided on both sides of the second flexible guide wheel 8. The rotating disks 20 are rotatably connected to the second flexible guide wheel 8, as Figure 3 shown. An annular groove is provided on the outer circumferential surface of the rotating disk 20, and the cross section is in an "H" shape. In this way, a connecting ring is provided at the position of the end face of the second flexible guide wheel 8 corresponding to the annular groove, and the connecting ring is buckled into the annular groove. In this way, the rotating disk 20 can rotate circumferentially relative to the second flexible guide wheel 8 without separation;

[0047] An extrusion disk 19 is provided at the outer end of the rotating disk 20. A plurality of protruding extrusion parts 21 are provided on the surface of the extrusion disk 19 facing the rotating disk 20. An end face extrusion force is applied to the rotating disk 20 through the extrusion disk 19 and the extrusion parts 21, so that the end faces on both sides of the second flexible guide wheel 8 undergo elastic deformation;

[0048] It further includes an extrusion bushing 18, which is installed at the outer end of the extrusion disk 19 and sleeved on the connecting shaft 17. The extrusion bushing 18 can rotate circumferentially relative to the connecting shaft 17. The extrusion bushing 18 is driven by a pulling drive mechanism. An assembly hole 184 is provided in the middle of the extrusion bushing 18, and the connecting shaft 17 passes through the assembly hole 184.

[0049] As Figure 5 shown, the extrusion bushing 18 includes a threaded connection section 181, an extrusion section 182, and a gear transmission section 183. A connecting shaft 17 hole is provided on the second support rod 10, and an internal thread section is provided on the inner wall of the connecting shaft 17 hole. The extrusion bushing 18 is threadedly connected to the internal thread section through the threaded connection section 181. The gear transmission section 183 is located within the connecting shaft 17 hole. The extrusion section 182 is in contact with the end face of the extrusion disk 19. The pulling drive mechanism is in gear engagement with the gear transmission section 183. When the pulling mechanism pulls, it drives the extrusion bushing 18 to rotate circumferentially and threadedly rotate relative to the internal thread section through the gear transmission section 183. At this time, the extrusion bushing 18 will move towards the second flexible guide wheel 8 without leaving the second support rod 10, achieving the purpose of extrusion.

[0050] As Figure 2 、 Figure 5 and Figure 6 shown, the pulling drive mechanism includes a pulling rack 16 and a pulling wire 15. One end of the pulling wire 15 is connected to the pulling rack 16, and the other end of the pulling wire 15 is connected to the load-bearing pulling section 3 of the second support rod 10.

[0051] The pulling rack 16 is installed in a rack installation groove within the second support rod 10. The rack installation groove communicates with the connecting shaft 17 hole. A part of the pulling rack 16 is located within the connecting shaft 17 hole and is in gear engagement with the gear transmission section 183. When the pulling wire 15 pulls the pulling rack 16, the pulling rack 16 drives the extrusion bushing 18 to rotate threadedly, thereby extruding the extrusion disk 19. The pulling force of the pipeline and the weight of the pipeline act on the load-bearing pulling section 3, and the load-bearing pulling section 3 can be used to make the pulling wire 15 perform a pulling action.

[0052] As Figure 1 shown, an elastic pressing mechanism is provided on one side between the first support rod 13 and the second support rod 10. Through the elastic pressing mechanism, the first flexible guide wheel 6 and the second flexible guide wheel 8 are always in guiding contact with the pipeline to be wound.

[0053] Specifically, the elastic pressing mechanism includes a fixed step 11 and a tension spring 12. The fixed step 11 is fixedly installed on the first support rod 13 and the second support rod 10 respectively. Both sides of the tension spring 12 are fixedly connected to the fixed step 11, and the first support rod 13 and the second support rod 10 are tightened by the tension spring 12.

[0054] Among them, the load-bearing pulling section 3 is elastically hinged to the second support rod 10. A torsion spring can be applied to achieve elastic hinging, which will not be specifically described here.

[0055] As Figure 1 shown, a lead screw connecting frame 5 is fixedly arranged at the top of the two first support rods 13. The lead screw connecting piece is connected to the servo drive mechanism, and the lead screw connecting piece is driven to move back and forth by the drive lead screw in the servo drive mechanism.

[0056] A guide bracket 7 is fixedly arranged at the bottom of the two second support rods 10. A guide groove is arranged at the bottom of the guide bracket 7. The guide bracket 7 is guidingly installed on a guide rod, and the guide groove is guidingly connected to the guide rod.

[0057] An adjustment mechanism of a reel provided by the present invention utilizes the weight of the pipeline itself and the pulling force generated during the winding process to act on the load-bearing wheel provided at the end of the adjustment mechanism, thereby driving the axially pressing mechanism linked thereto, causing elastic deformation of the end faces on both sides of the second flexible guide wheel towards the pipeline direction and achieving effective clamping. Thus, during the left-right reciprocating axial movement of the guide mechanism, the friction force between the guide wheel and the pipeline is significantly increased, effectively preventing the pipeline from slipping, ensuring that the pipeline can move synchronously with the adjustment mechanism, and achieving a more accurate and uniform winding effect.

[0058] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any change or replacement that can be thought of without creative work should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
