Description

Technical Field

[0001] The present invention relates to the technical field of winding devices, and particularly relates to a winding device for IXPE foam production. Background Art

[0002] XPE foam, namely electron cross-linked polyethylene foam and radiation cross-linked polyethylene foam, has low-density polyethylene (LDPE) as its main raw material, supplemented with auxiliary materials such as foaming agents. After being melted, mixed evenly and extruded into a shape, through radiation processing technology, it undergoes green and healthy ionizing radiation cross-linking, and then is continuously foamed at high temperature to form a foam product. In order to reduce the storage space, after the XPE foam is produced, it needs to be wound by a winding device, that is, a reel is sleeved on the reel of the winding device, with the discharging end of the XPE foam as the starting point of the reel. The reel drives the reel to rotate, so that the XPE foam is wound onto the reel.

[0003] However, the surface of the reel is smooth, and the reel is sleeved on the reel and bears radial tension, resulting in axial or radial slipping of the reel, affecting normal winding. The pure manual fixing method requires multiple steps of operation and has low efficiency. Summary of the Invention

[0004] In order to solve the above problems, the present invention provides a winding device for IXPE foam production, including a shaft assembly, a scissor assembly, a positioning assembly and a reel. The shaft assembly includes a horizontal shaft with a disc at the inner end and a driving member sliding on the horizontal shaft. An axial locking member is installed on the disc and a jack is provided. The driving member is equipped with a driving seat. The scissor assembly has at least three groups arranged in a circular array. The inner side is hinged to the driving member and the horizontal shaft, and the outer side is hinged to a radial locking plate. The positioning assembly includes a radially acting rod and an axial locking rod. The inner end of the radially acting rod abuts against the driving seat, the outer end extends towards the inner end of the radial locking plate and is equipped with a receiving seat. The axial locking rod is connected to a pressing rod and is provided with a locking portion that is locked relative to the axial locking member. The end of the reel is provided with a pressing rod. While the pressing rod triggers the receiving seat to provide a radial locking force to the radial locking plate, it also causes the axial locking rod to reach the axial locking member along the jack and be axially locked.

[0005] As a further preferred option, the outer end face of the disc is provided with a convex portion that is on the same straight line as and communicates with the jack. The axial locking member is installed on the convex portion and is perpendicular to the axial locking rod. The locking portion is a locking hole opened on the axial locking rod, and the axial locking member is a spring pin.

[0006] As a further preferred option, the radial locking plate is an arc-shaped plate. The inner cavity wall of the reel is provided with a positioning guide rail that coincides with the space between two adjacent radial locking plates. The inner end of the reel is provided with a circular baffle. The pressing rod is installed on the inner end face of the circular baffle. A communicating relief hole is provided among the receiving seat, the radially acting rod, the disc and the convex portion. The axial locking rod is on the same straight line as the relief hole.

[0007] As a further preference, a sleeve is connected to the inner end of the horizontal shaft, the disc is mounted on the inner end of the sleeve, an axially acting rod is connected to the inner end of the driving member, the inner end of the axially acting rod enters the sleeve, the driving seat is located inside the sleeve and is connected to the inner end of the axially acting rod, and the inner end of the radially acting rod extends radially into the sleeve and abuts against the driving seat.

[0008] As a further preference, an assembly frame is fixed on the inner surface of the disc. The assembly frame is provided with an assembly groove in the radial direction of the disc. An assembly seat moving radially is slidably assembled on the assembly groove. The outer end of the radially acting rod extends from the assembly hole into the assembly frame and is connected to the assembly seat. The inner end of the driving seat is provided with an inclined surface opposite to the radial force of the inner end of the radially acting rod. The pressure-applying rod extends horizontally. The receiving seat is inclined downward in the linear movement direction of the pressure-applying rod. A spring is elastically supported between the bottom of the assembly frame and the assembly seat. The spring is sleeved on the radially acting rod.

[0009] As a further preference, there are two axially acting rods symmetrically arranged on both sides of the horizontal shaft. The inner ends of the two axially acting rods simultaneously extend into the sleeve to connect the driving seat, and the outer ends of the two axially acting rods simultaneously extend out and are commonly connected to the driving member through a connecting plate.

[0010] As a further preference, a circle of weight-reducing holes is provided on the circular baffle, and the opening positions of at least one weight-reducing hole are opposite to the inside and outside of the axial locking rod.

[0011] As a further preference, the part of the relief hole on the radially acting rod is opened from the top side to the bottom side of the receiving seat along the length direction of the radially acting rod.

[0012] The beneficial effects of the present invention compared with the prior art are:

[0013] 1. When the reel is placed above the locking plate, the pressure-applying rod is squeezed on the receiving seat. The receiving seat generates a radial force under the force, and drives the radially acting rod to move radially towards the axis direction of the horizontal shaft. The inner end of the radially acting rod radially squeezes the driving seat, so that the driving seat drives the axially acting rod to perform a linear movement outwards. The axially acting rod pushes the driving member, and all the scissor assemblies perform a radial expansion movement. All the radial locking plates move radially in the peripheral direction of the horizontal shaft. The radial locking force is provided to the inner wall of the reel through the radial movement of the radial locking plate, so that the reel is locked on the radial locking plate to prevent circumferential and axial detachment. When the reel winds the IXPE foam, the radial locking plate forms a large radial locking force on the inner wall of the reel. Therefore, it can prevent the reel from slipping, and at the same time, this radial locking force can also prevent the reel from axially slipping and detaching during winding.

[0014] 2. When the pressing rod squeezes the receiving seat to move radially, the axial locking rod is sent to the axial locking member, and the axial locking member axially locks the axial locking member on the disc. When the axial locking member axially locks the locking rod, it is equivalent to providing an axial locking force to the drum and axially locking the drum on the radial locking plate. Coupled with the radial and axial locking effects generated by the expansion of the radial locking plate against the drum wall, the axial detachment of the drum can be further prevented.

[0015] 3. Structurally, the pressing rod and the axial locking rod are arranged on the drum, with a simple structure, and other power components are arranged on the winding device opposite thereto; in terms of installation, when the drum is placed on the winding device, the driving relationship can be established between the pressing rod and the axial locking rod and the above-mentioned components on the winding device, and the drum can be quickly fixed in a multi-axial and multi-radial locking manner, not only improving the anti-slip and anti-detachment effects, but also facilitating operation.

Detailed implementation manners

[0025] The above and other implementation manners and advantages of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described implementation manners are only part of the implementation manners of the present invention, rather than all of them.

[0026] In one implementation manner, as Figures 1-8 shown:

[0027] This implementation manner provides a winding device for IXPE foam production, including a shaft assembly 10, a scissor assembly 20, a positioning assembly 30 and a reel 40. The shaft assembly 10 includes a horizontal shaft 110 with a disc 1102 at the inner end and a driving part 120 sliding on the horizontal shaft 110. An axial locking part 1107 is installed on the disc 1102 and a jack 1108 is provided. The driving part 120 is equipped with a driving seat 1202. The scissor assembly 20 is at least three groups in a circular array, hinged to the driving part 120 and the horizontal shaft 110 at the inner side and hinged to a radial locking plate 210 at the outer side. The positioning assembly 30 includes a radial force rod 310 and an axial locking rod 320. The inner end of the radial force rod 310 abuts against the driving seat 1202, the outer end extends to the inner end of the radial locking plate 210 and is equipped with a receiving seat 3101. The axial locking rod 320 is connected to the pressing rod 410 and is provided with a locking part 3201 that locks relative to the axial locking part 1107. The end of the reel 40 is provided with a pressing rod 410. While the pressing rod 410 triggers the receiving seat 3101 to provide a radial locking force to the radial locking plate 210, it also makes the axial locking rod 320 reach the axial locking part 1107 along the jack 1108 to be axially locked.

[0028] In this embodiment, when the reel 40 is placed above the locking plate 210, the pressing rod 410 is pressed against the receiving seat 3101. The receiving seat 3101 generates a radial force under the force, and drives the radial force rod 310 to move radially in the axial direction of the horizontal shaft 110. The inner end of the radial force rod 310 radially presses the driving seat 1202, and the driving member 120 is pushed by the axial force rod 1201 to move along the horizontal shaft 110 towards the outer end of the reel 40. The driving member 120 pushes all the scissor assemblies 20 to expand radially. The scissor assemblies 20 drive all the radial locking plates 210 to move radially in the circumferential direction around the horizontal shaft 110. The radial movement of the radial locking plates 210 provides a radial locking force to the inner wall of the reel 40, locking the reel 40 on the radial locking plates 210 to prevent circumferential and axial detachment. A flange is provided at the innermost end of the sleeve 1101 to connect the winding device to the rotating pair on the winding equipment. The rotating pair drives the sleeve 1101 to rotate, the sleeve 1101 drives the horizontal shaft 110 to rotate, the horizontal shaft 110 drives the axial force rod 1201 and the axial force rod 1201 drives the driving member 120 to rotate. The driving member 120 drives the scissor assemblies 20 to rotate, and the scissor assemblies 20 drive the radial locking plates 210 to rotate. Under the radial expansion of the radial locking plates 210, the reel 40 is driven to rotate and wind the IXPE foam. When winding the IXPE foam, a pulling force will be generated, which may cause the reel 40 to slip. However, in the present invention, when the reel 40 is sleeved on the device, through the above series of action transmission methods, a large radial locking force is formed by the radial locking plates 210 on the inner wall of the reel 40. Therefore, the reel 40 can be prevented from slipping. At the same time, this radial locking force can also prevent the reel 40 from axially slipping and detaching during winding.

[0029] In this embodiment, when the pressing rod 410 presses the receiving seat 3101 to move radially, the axial locking rod 320 will also be sent to the axial locking member 1107 along the jack 1108. The axial locking member 1107 enters the locking portion and axially locks the axial locking member 1107 on the disc 1102. Since the axial locking rod 320 is installed on the pressing rod 410, and the pressing rod 410 is an axial component on the reel 40. Also, since the axial locking member 1107 is a component on the disc 1102, and the disc 1102 is installed on the winding equipment together with the entire winding device. Therefore, when the axial locking member 1107 axially locks the axial locking rod 320, it is equivalent to providing an axial locking force to the reel 40 and axially locking the reel 40 on the radial locking plates 210. Coupled with the radial and axial locking effects generated by the expansion of the radial locking plates 210 on the inner wall of the reel 40, the axial detachment of the reel 40 can be further prevented.

[0030] In terms of structure in this embodiment, the pressing rod 410 and the axial locking rod 320 are arranged on the reel 40, with a simple structure, and other power components are arranged on the winding device opposite thereto; in terms of installation, as the reel 40 is placed on the winding device, the driving relationship can be established between the pressing rod 410 and the axial locking rod 320 and the above-mentioned components on the winding device, and the reel 40 can be quickly fixed in a multi-axial and multi-radial locking manner, which not only improves the anti-slip and anti-detachment effects, but also is convenient for operation, saves operation steps, and improves work efficiency.

[0031] As Figure 3 , Figure 7 shown, a convex portion 1106 that is collinear and communicates with the jack 1108 is provided on the outer end face of the disc 1102. The axial locking member 1107 is installed on the convex portion 1106 and is perpendicular to the axial locking rod 320. The locking portion 3201 is a locking hole opened on the axial locking rod 320, and the axial locking member 1107 is a spring pin. The convex portion 1106 extends horizontally towards the outer end face of the disc 1102. The end of the axial locking member 1107 is provided with a chamfered surface. The axial locking member 1107 is installed on the convex portion 1106 in the form of a spring pin and is perpendicular to the part of the jack 1108 within the convex portion 1106. When the axial locking rod 320 enters the convex portion 1106 from the jack 1108, first use the chamfered surface to push the pin rod of the spring pin outwards from the axis of the jack 1108 until its locking hole coincides with the inner end of the pin rod, and then the pin rod rebounds into the locking hole, quickly locking the axial locking member 1107 within the convex portion 1106, locking the convex portion 1106 on the disc 1102, and locking the disc 1102 on the winding device of the present invention.

[0032] The radial locking plate 210 is an arc-shaped plate. When the reel 40 is sleeved on it, the outer circular surface of the radial locking plate 210 fits with the cavity wall of the reel 40. A positioning guide rail 420 that coincides with the space between two adjacent radial locking plates 210 is provided on the inner cavity wall of the reel 40. When the reel 40 is placed on the winding device along the radial locking plate 210, its positioning guide rail 420 moves linearly along the gap between the two radial locking plates 210, and at the same time, the positioning guide rail 420 is restricted and locked between the two radial locking plates 210, and through the directional pushing method of the positioning guide rail 420, the pressing rod 410 at the inner end of the reel 40 is accurately positioned on the receiving seat 3101, quickly triggering the locking action.

[0033] In another embodiment, as Figure 2 , Figure 3 shown, a circular baffle 430 is provided at the inner end of the reel 40. The pressing rod 410 is installed on the inner end face of the circular baffle 430. A communicating relief hole 50 is provided between the receiving seat 3101, the radial force rod 310, the disc 1102, and the convex portion 1106. The axial locking rod 320 is collinear with the relief hole 50.

[0034] In this embodiment, the circular baffle 430 is used to mount the pressure rod 410. Second, when the axial locking rod 320 is inserted into the convex part 1106 and locked by the axial locking part 1107 by the pressure rod 410, a safety distance is also formed between the circular baffle 430 and the disc 1102. When the reel 40 is wound up, contact between the IXPE foam and the components on the disc 1102 and components such as the pressure rod 410 is avoided.

[0035] In another embodiment, a mutually communicating relief hole 50 is provided between the receiving seat 3101, the radially acting rod 310, the disc 1102, and the convex part 1106. The axial locking rod 320 and the relief hole 50 are on the same straight line, so that when the pressure rod 410 moves linearly to the receiving seat 3101 and uses the inclined surface to push the receiving seat 3101, the receiving seat 3101 is forced to push the radially acting rod 310 towards the driving seat 1202, triggering the driving seat 1202 and causing the driving seat 1202 to drive the driving member 120 to move linearly outwards. In addition to the radial expansion of the scissor assembly 20 triggered by the driving member 120, it is ensured that the pressure rod 410 passes through the insertion hole 1108 and enters the convex part 1106. In particular, the part of the relief hole 50 on the radially acting rod 310 is opened from the top side to the bottom side of the receiving seat 3101 along the length direction of the radially acting rod 310. The radially acting rod 310 takes the relief hole 50 as the maximum movement space, and when the radially acting rod 310 moves radially, it will not obstruct the linear (axial) movement of the pressure rod 410 with the axial locking rod 320 towards the axial locking part 1107.

[0036] In another embodiment, as Figure 3 、 Figure 8 shown, the inner end of the horizontal shaft 110 is connected with a sleeve 1101, the disc 1102 is installed on the inner end of the sleeve 1101, the inner end of the driving member 120 is connected with an axially acting rod 1201, the inner end of the axially acting rod 1201 enters the sleeve 1101, the driving seat 1202 is located in the sleeve 1101 and is connected to the inner end of the axially acting rod 1201, and the inner end of the radially acting rod 310 radially extends into the sleeve 1101 and abuts against the driving seat 1202.

[0037] In this embodiment, the sleeve 1101 is a structure extending from the inner end of the horizontal shaft 110. The lumen of the sleeve 1101 is used as the movement space for the trigger ends of the axial force rod 1201 and the radial force rod 310. At the same time, the sleeve 1101 slidably connects the axial force rod 1201 to the horizontal shaft 110. The inner end of the sleeve 1101 is connected to the rotary pair on the winding device through a flange. Not only does the rotation of the rotary pair ensure that the sleeve 1101 drives the axial force rod 1201 and the horizontal shaft 110 to rotate, and the axial force rod 1201 drives the driving member 120 to rotate, but also when the reel 40 is placed on the winding device, through the above power transmission relationship, it is ensured that the driving member 120 can move linearly along the horizontal shaft 110.

[0038] In another embodiment, as Figure 2 , Figure 3 , Figure 7 and Figure 8 shown, an assembly frame 1103 is fixed on the inner surface of the disc 1102. The assembly frame 1103 is provided with an assembly groove 1104 along the radial direction of the disc 1102. An assembly seat 1105 that moves radially is slidably assembled on the assembly groove 1104. The outer end of the radial force rod 310 extends into the assembly frame 1103 through the assembly hole 1112 and is connected to the assembly seat 1105. The inner end of the driving seat 1202 is provided with an inclined surface 1203 that is radially opposite to the radial force of the inner end of the radial force rod 310. The pressing rod 410 extends horizontally, and the receiving seat 3101 is inclined downward in the linear movement direction of the pressing rod 410. A spring 135 is elastically supported between the bottom of the assembly frame 1103 and the assembly seat 1105. The spring 135 is sleeved on the radial force rod 310.

[0039] In this embodiment, when the pressing rod 410 moves linearly until its inner end presses against the inner inclined surface of the receiving seat 3101, the receiving seat 3101 will drive the radial force rod 310 to move radially. When the radial force rod 310 moves radially, the assembly seat 1105 moves radially along the assembly groove 1104 in the axial direction, and the spring 135 is compressed and shortened to ensure the smooth radial movement of the radial force rod 310. At the same time, under the orientation of the assembly seat 1105 in the assembly groove 1104, the accurate alignment between the receiving seat 3101 and the pressing rod 410 is ensured. After winding, the axial lock 1107 is pulled away from the axial lock rod 320, and the axial lock rod 320 is freed. The driving reel 40 is pushed in the reverse direction, and the axial lock rod 320 and the pressing rod 410 are dragged in the reverse direction by the reel 40. The axial lock rod 320 retracts to the inner side of the disc 1102, the pressing rod 410 leaves the receiving seat 3101, the radial force on the receiving seat 3101 disappears, the spring 135 resumes its length, and pushes the assembly seat 1105 to radially reset in the direction away from the axis. The inner end of the radial force rod 310 leaves the driving seat 1202, the axial thrust of the driving seat 1202 on the axial force rod 1201 disappears, the axial thrust of the axial force rod 1201 on the driving member 120 disappears, the expansion force of the driving member 120 on the scissor assembly 20 disappears, the radial thrust of the scissor assembly 20 on the radial locking plate 210 disappears, the radial locking force of the radial locking plate 210 on the reel 40 disappears, and the reel 40 can be quickly removed.

[0040] The axial force rods 1201 are two symmetrically arranged on both sides of the horizontal axis 110. The inner ends of the two axial force rods 1201 simultaneously extend into the sleeve 1101 to connect the driving seat 1202, and the outer ends of the two axial force rods 1201 simultaneously extend out and are commonly connected to the driving member 120 through a connecting plate.

[0041] A circle of weight-reducing holes 4301 are provided on the circular baffle 430, and at least one weight-reducing hole 4301 is arranged opposite to the axial lock rod 320 inside and outside.

[0042] The above orientation references do not represent the specific orientations of the components in this implementation scheme. This implementation scheme is only for the convenience of describing the scheme and is set with relative descriptions referring to the orientations in the figure. In essence, the specific orientations of the components are based on their actual installation, actual use, and the habitual orientation descriptions of those skilled in the art. This is hereby explained.

[0043] The above specific implementation manners have further elaborated on the invention purpose, technical solutions, and beneficial effects of the present invention. It should be understood that the above are only the specific implementation manners of the present invention and are not used to limit the protection scope of the present invention.
