Description

Technical Field

[0001] This utility model relates to the field of coiling mechanisms, and in particular to a coiling mechanism for rubber hoses. Background Technology

[0002] The coiling mechanism is a structure on a coiling machine used to neatly wind hoses (such as rubber hoses, plastic hoses, etc.). Currently, common coiling mechanisms typically consist of a drum and a support frame. Before coiling, the operator must manually secure the hose end to the drum, usually using bolts, clamps, or straps to prevent slippage during the initial winding process. After coiling, the operator needs to untie the hose end to easily remove the coiled hose from the coiling mechanism. Both securing and untieing the hose end during coiling are time-consuming and cumbersome, hindering coiling efficiency.

[0003] Based on this, the present invention provides a coiling mechanism for hoses. By optimizing the fixing structure at the end of the hose, the fixing structure at the end of the hose can be automatically released when the coiled hose is removed after coiling, that is, there is no need to perform an additional operation to release the fixing structure at the end of the hose, thereby improving the coiling efficiency of the coiling machine. Utility Model Content

[0004] Therefore, it is necessary to provide a coiling mechanism for hoses, including a cylindrical drive shaft arranged along the front-rear direction. A plurality of support frames are fixedly mounted at the front end of the drive shaft, and the support frames are evenly arranged around the axis of the drive shaft. Each support frame includes a first stop fixedly mounted at the front end of the drive shaft and arranged along the radial direction of the drive shaft. A connecting arm is fixedly mounted on the front side wall of the first stop, and the connecting arm is arranged parallel to the axial direction of the drive shaft. The support frame also includes a second stop parallel to the first stop. A mounting seat is fixedly mounted on the side wall of the connecting arm facing the drive shaft, and a connecting block is mounted on the rear side wall of the second stop corresponding to the mounting seat. The connecting block is pivotally connected to the mounting seat and can swing back and forth. The support frame also includes a support plate. The support plate is located on the side of the connecting arm away from the drive shaft. The support plate is connected to the connecting arm via multiple connecting rods perpendicular to the connecting arm. The upper and lower ends of the connecting rods are pivotally connected to the support plate and the connecting arm, respectively, and the front and rear ends of the support plate abut against the second stop and the first stop, respectively. The support frame also includes a clamping device, which includes an adjusting device disposed on the rear side wall of the first stop and a pressure plate perpendicular to the first stop. The pressure plate is disposed on the first stop by means of the adjusting device, and extends through the opening in the first stop to the side of the support plate away from the drive shaft. The pressure plate and the support plate enclose each other to form a fixing clamp.

[0005] In this invention, the coiling mechanism is used on a coiling machine to neatly wind the hose onto it. The drive shaft of the coiling mechanism is connected to the drive mechanism of the coiling machine so that it can rotate under the drive of the drive mechanism, thereby realizing the coiling operation of the coiling mechanism.

[0006] In this invention, the support frame is evenly arranged around the drive shaft, and correspondingly, the support plates on the support frame are also evenly arranged around the drive shaft, thus forming a support cylinder for coiling the hose. The second stop and the first stop respectively abut against the front and rear ends of the support plate, which can fix and limit the support plate. At the same time, the second stop and the first stop located at the front and rear ends of the support cylinder can also be used to block and limit the hose coiled on the support cylinder to prevent the hose from slipping off the support cylinder during the coiling process. The fixing clamp formed by the pressure plate and the support plate is used to fix the end of the hose. Specifically, the fixing method is to move the pressure plate toward the support plate through the adjusting device, thereby clamping the end of the hose between the pressure plate and the support plate to fix the end of the hose.

[0007] In this invention, the second stop lever is pivotally mounted on the connecting arm via a connecting block and a mounting seat on the connecting arm. Therefore, after the hose is coiled, swinging the second stop lever forward releases its obstruction of the coiled hose roll. Pulling the hose roll forward then removes it from the coiling mechanism, completing the hose roll unloading operation. Simultaneously, since the support plate is pivotally connected to the connecting arm via a connecting rod, the hose can move the support plate forward and towards the connecting arm during hose roll removal. This increases the distance between the pressure plate and the support plate, effectively releasing the pressure plate's fixation on the hose end. Thus, this invention automatically releases the hose end fixation structure while removing the coiled hose roll, eliminating the need for additional unfixation operations and improving the coiling efficiency of the coiling machine.

[0008] Furthermore, the clamping device includes a mounting block fixedly disposed on the rear side wall of the first stop bar. The mounting block has a threaded mounting hole along a direction parallel to the first stop bar. An adjusting screw is disposed in the threaded mounting hole. A limit plate is fixedly disposed at the end of the adjusting screw away from the drive shaft. The pressure plate has a through-hole corresponding to the adjusting screw. The through-hole is sleeved on the adjusting screw and is movably engaged with the adjusting screw.

[0009] In this invention, the adjusting screw is installed in the threaded mounting hole of the mounting block. By rotating the adjusting screw, the limiting plate on it pushes the pressure plate, thereby bringing the pressure plate closer to the support plate to press and fix the end of the hose, allowing the coiled hose to be easily removed from the coiling mechanism. When it is necessary to further fix the end of the hose, simply rotate the adjusting screw to move the limiting plate away from the support plate, and the next hose end fixing operation can be performed.

[0010] In this invention, preferably, a handle or turntable is fixedly provided at the lower end of the adjusting screw to facilitate rotation of the adjusting screw.

[0011] Furthermore, in this invention, the connecting hole is sleeved on and movably fitted with the adjusting screw, meaning the inner diameter of the connecting hole is larger than the diameter of the adjusting screw. Therefore, for support frames that do not require fixing the end of the hose, the pressure plate can freely fall onto the support plate during the rotation of the support frame, thus avoiding any impact on the hose winding process. Of course, if the natural falling of the pressure plate is used to avoid affecting the hose winding, the hose needs to be wound into the support cylinder from the top. Therefore, it is best to fix it to the support plate using the adjusting screw to ensure that its influence on the hose winding process is eliminated.

[0012] Furthermore, at least two limiting rods are provided inside the window along the length of the first stop rod. The pressure plate has a limiting hole corresponding to the limiting rod. The limiting hole is sleeved on the corresponding limiting rod. The inner sidewall of the limiting hole and the outer sidewall of the limiting rod are fitted together and slidably engaged.

[0013] In this invention, the limiting rod inside the window is inserted into the limiting hole and is slidably fitted with the limiting hole to limit the displacement path of the pressure plate, so that the pressure plate always remains in the direction perpendicular to the first stop, thereby ensuring the reliability of the fixing effect of the pressure plate on the end of the hose.

[0014] Furthermore, the rear end of the support plate is provided with a receiving groove for accommodating the pressure plate, and the depth of the receiving groove is not less than the thickness of the pressure plate.

[0015] In this invention, the receiving groove on the support plate can accommodate the pressure plate. Therefore, by adjusting the screw to fix the pressure plate in the receiving groove, the pressure plate can be prevented from protruding from the surface of the support plate, thereby completely eliminating the influence of the pressure plate on the hose winding process.

[0016] Furthermore, the portion of the second stop lever located between the connecting block and the drive shaft forms a connecting section; a drive cylinder is also fixedly installed on the side wall of the connecting arm facing the drive shaft, the piston rod of the drive cylinder is arranged parallel to the axial direction of the drive shaft, and one end of the piston rod facing the second stop lever is connected to the connecting section of the second stop lever through a connecting post, and the two ends of the connecting post are pivotally connected to the piston rod and the connecting section respectively, which can swing up and down.

[0017] In this invention, the fixing and swinging of the second stop lever on the connecting arm are both accomplished by the drive cylinder connected to it. When the piston rod of the drive cylinder is fixed, the second stop lever is fixed. When the piston rod of the drive cylinder moves backward, it can drive the top of the second stop lever to swing forward, thereby moving the second stop lever into the space between the support plate and the transmission shaft. At this time, the obstruction of the second stop lever on the rubber tube roll on the support cylinder can be released.

[0018] Furthermore, the second stop lever is disposed abutting against the front end of the connecting arm.

[0019] In this invention, when the second stop lever is parallel to the first stop lever, the second stop lever abuts against the front end of the connecting arm. That is, the connecting arm can support and limit the second stop lever. When the drive cylinder drives the upper end of the second stop lever to swing backward, the positioning of the second stop lever can be completed quickly, so that it remains parallel to the second stop lever.

[0020] Furthermore, the connecting rod is pivotally connected to the left and right side walls of the connecting arm.

[0021] In this invention, the connecting rod connecting the connecting arm and the support plate is pivotally connected to the left and right side walls of the connecting arm. Therefore, as the tape roll moves the support plate forward and closer to the connecting arm, the connecting rod can be effectively prevented from being squeezed by the support plate, thus avoiding damage to the connecting rod from compression.

[0022] The principle and effects of this utility model will be further explained below with reference to the above technical solution and the accompanying drawings:

[0023] In this invention, the second stop lever is pivotally mounted on the connecting arm via a connecting block and a mounting seat on the connecting arm. Therefore, after the hose is coiled, swinging the second stop lever forward releases its obstruction of the coiled hose. Pulling the coiled hose forward then removes it from the coiling mechanism, completing the hose unloading operation. Simultaneously, since the support plate is pivotally connected to the connecting arm via a connecting rod, the hose can move the support plate forward and downward during hose removal, increasing the distance between the pressure plate and the support plate, thus releasing the pressure plate's fixation on the hose end. Therefore, this invention automatically releases the hose end fixation structure while removing the coiled hose, eliminating the need for additional removal operations and improving the coiling efficiency of the coiling machine.

Detailed Implementation

[0032] To facilitate understanding by those skilled in the art, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments:

[0033] like Figure 1-6 A coiling mechanism for hoses includes a cylindrical drive shaft 1 arranged along a front-rear direction. A plurality of support frames are fixedly mounted at the front end of the drive shaft 1, and the support frames are evenly arranged around the axis of the drive shaft 1. Each support frame includes a first stop 21 fixedly mounted at the front end of the drive shaft 1 and arranged along the radial direction of the drive shaft 1. A connecting arm 23 is fixedly mounted on the front side wall of the first stop 21, and the connecting arm 23 is arranged parallel to the axial direction of the drive shaft 1. The support frame also includes a second stop 22 arranged parallel to the first stop 21. A mounting base 232 is fixedly mounted on the side wall of the connecting arm 23 facing the drive shaft 1. A connecting block 221 is mounted on the rear side wall of the second stop 22 corresponding to the mounting base 232. The connecting block 221 is pivotally connected to the mounting base 232, allowing it to swing back and forth. The support frame also includes a support plate 24, which is located at... The connecting arm 23 is located away from the drive shaft 1. The support plate 24 is connected to the connecting arm 23 via multiple connecting rods 231 perpendicular to the connecting arm 23. The upper and lower ends of the connecting rods 231 are pivotally connected to the support plate 24 and the connecting arm 23, respectively, and the front and rear ends of the support plate 24 abut against the second stop 22 and the first stop 21, respectively. The support frame also includes a clamping device, which includes an adjusting device disposed on the rear side wall of the first stop 21 and a pressure plate 31 perpendicular to the first stop 21. The pressure plate 31 is disposed on the first stop 21 and can be reciprocated along the length direction of the first stop 21 by the adjusting device. The pressure plate 31 extends through the opening in the first stop 21 to the side of the support plate 24 away from the drive shaft 1. The pressure plate 31 and the support plate 24 enclose each other to form a fixing clamp.

[0034] In this utility model, the coiling mechanism is used on a coiling machine to neatly wind the hose onto it. The drive shaft 1 of the coiling mechanism is connected to the drive mechanism of the coiling machine so that it can rotate under the drive of the drive mechanism, thereby realizing the coiling operation of the coiling mechanism.

[0035] In this invention, the support frame is evenly arranged around the drive shaft 1, and correspondingly, the support plate 24 on the support frame is also evenly arranged around the drive shaft 1, thus forming a support cylinder for coiling the hose. The second stop 22 and the first stop 21 abut against the front and rear ends of the support plate 24 respectively, which can fix and limit the support plate 24. At the same time, the second stop 22 and the first stop 21 located at the front and rear ends of the support cylinder can also be used to block and limit the hose coiled on the support cylinder to prevent the hose from slipping off the support cylinder during the coiling process. The fixing clamp formed by the pressure plate 31 and the support plate 24 is used to fix the end of the hose. Specifically, the fixing method is to move the pressure plate 31 toward the support plate 24 through the adjusting device, thereby clamping the end of the hose between the pressure plate 31 and the support plate 24 to fix the end of the hose.

[0036] In this invention, the second stop 22 is pivotally mounted on the connecting arm 23 via a connecting block 221 and a mounting seat 232 on the connecting arm 23. Therefore, after the hose is coiled, swinging the second stop 22 forward releases its obstruction of the coiled hose roll. Pulling the hose roll forward then removes it from the coiling mechanism, completing the hose roll unloading operation. Simultaneously, since the support plate 24 is pivotally connected to the connecting arm 23 via the connecting rod 231, during hose roll removal, the hose can move the support plate 24 forward and towards the connecting arm 23, increasing the distance between the pressure plate 31 and the support plate 24, thus releasing the pressure plate 31 from fixing the hose end. Therefore, this invention automatically releases the hose end fixing structure while removing the coiled hose roll, eliminating the need for additional hose end fixing operations, thereby improving the coiling efficiency of the coiling machine.

[0037] In one embodiment, the clamping device includes a mounting block 32 fixedly disposed on the rear side wall of the first stop 21. The mounting block 32 has a threaded mounting hole along a direction parallel to the first stop 21. An adjusting screw 33 is disposed in the threaded mounting hole. A limit plate 331 is fixedly disposed at one end of the adjusting screw 33 away from the drive shaft 1. The pressure plate 31 has a through-hole corresponding to the adjusting screw 33. The through-hole is sleeved on the adjusting screw 33 and is movably engaged with the adjusting screw 33.

[0038] In this embodiment, the adjusting screw 33 is installed in the threaded mounting hole of the mounting block 32. By rotating the adjusting screw 33, the limiting plate 331 on it can be driven to push the pressure plate 31, thereby bringing the pressure plate 31 closer to the support plate 24 to press and fix the end of the hose, so that the coiled hose can be easily removed from the coiling mechanism. When it is necessary to continue fixing the end of the hose, simply rotate the adjusting screw 33 to move the limiting plate 331 away from the support plate 24 to perform the next fixing operation of the hose end.

[0039] In this embodiment, preferably, a handle or turntable is fixedly provided at the lower end of the adjusting screw 33 to facilitate rotation of the adjusting screw 33.

[0040] In addition, in this embodiment, the connecting hole is sleeved on and movably fitted with the adjusting screw 33, meaning the inner diameter of the connecting hole is larger than the diameter of the adjusting screw 33. Therefore, for support frames that do not require fixing of the hose end, the pressure plate 31 can freely fall onto the support plate 24 during the rotation of the support frame, thus avoiding any impact on the hose winding process. Of course, if the natural falling of the pressure plate 31 is to prevent any impact on the hose winding, the hose needs to be wound into the support cylinder from the top. Therefore, it is best to fix it to the support plate 24 using the adjusting screw 33 to ensure that its influence on the hose winding process is eliminated.

[0041] In one embodiment, at least two limiting rods are provided inside the window along the length of the first stop bar 21. The pressure plate 31 has a limiting hole corresponding to the limiting rod. The limiting hole is sleeved on the corresponding limiting rod. The inner sidewall of the limiting hole and the outer sidewall of the limiting rod are fitted together and slidably engaged.

[0042] In this embodiment, the limiting rod inside the window is inserted into the limiting hole and is slidably fitted with the limiting hole to limit the displacement path of the pressure plate 31, so that the pressure plate 31 is always kept in the direction perpendicular to the first stop 21, thereby ensuring the reliability of the fixing effect of the pressure plate 31 on the end of the hose.

[0043] In one embodiment, the rear end of the support plate 24 is provided with a receiving groove for accommodating the pressure plate 31, and the depth of the receiving groove is not less than the thickness of the pressure plate 31.

[0044] In this embodiment, the receiving groove on the support plate 24 can accommodate the pressure plate 31. Therefore, by adjusting the screw 33 to fix the pressure plate 31 in the receiving groove, the pressure plate 31 can be prevented from protruding from the surface of the support plate 24, thereby completely eliminating the influence of the pressure plate 31 on the hose winding process.

[0045] In one embodiment, the portion of the second stop 22 located between the connecting block 221 and the drive shaft 1 forms a connecting section; a drive cylinder 25 is also fixedly installed on the side wall of the connecting arm 23 facing the drive shaft 1, the piston rod of the drive cylinder 25 is arranged parallel to the axial direction of the drive shaft 1, and one end of the piston rod facing the second stop 22 is connected to the connecting section of the second stop 22 through a connecting post 26, and the two ends of the connecting post 26 are pivotally connected to the piston rod and the connecting section respectively, which can swing up and down.

[0046] In this embodiment, the fixing and swinging of the second stop lever 22 on the connecting arm 23 are both accomplished by the drive cylinder 25 connected to it. When the piston rod of the drive cylinder 25 is fixed, the second stop lever 22 is fixed. When the piston rod of the drive cylinder 25 moves backward, it can drive the top of the second stop lever 22 to swing forward, thereby moving the second stop lever 22 into the space between the support plate 24 and the transmission shaft 1. At this time, the obstruction of the second stop lever 22 on the rubber tube roll on the support cylinder can be released.

[0047] In one embodiment, the second stop 22 is disposed abutting against the front end of the connecting arm 23.

[0048] In this embodiment, when the second stop lever 22 is parallel to the first stop lever 21, the second stop lever 22 abuts against the front end of the connecting arm 23. That is, the connecting arm 23 can support and limit the second stop lever 22. When the drive cylinder 25 drives the upper end of the second stop lever 22 to swing backward, the positioning of the second stop lever 22 can be completed quickly, so that it remains parallel to the second stop lever 22.

[0049] In one embodiment, the connecting rod 231 is pivotally connected to the left and right side walls of the connecting arm 23.

[0050] In this embodiment, the connecting rod 231 connecting the connecting arm 23 and the support plate 24 is pivotally connected to the left and right side walls of the connecting arm 23. Therefore, during the process of the tape roll driving the support plate 24 forward and close to the connecting arm 23, the connecting rod 231 can be effectively prevented from being squeezed by the support plate 24, thereby avoiding damage to the connecting rod 231 from compression.

[0051] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
