Description

Technical Field

[0001] The utility model relates to the technical field of winding devices, and in particular to a reciprocating waste edge winding device. Background Art

[0002] At present, in the plastic extrusion molding process, it is often necessary to trim the edges of plastic products and cut off the waste strips on both sides to obtain the required product size and shape. In this process, the cut waste strips need to be collected and processed by a waste strip winding device. However, in the existing waste strip winding device, the utilization rate of the winding core is not high, and the waste strips are often not evenly distributed on every part of the winding core.

[0003] A search revealed a Chinese utility model patent with authorization announcement number CN208898206U, which discloses a waste edge winding device. This patent, through structural adjustment, utilizes a spring and bolt to softly connect the handle, and provides a hinged first folding piece and a second folding piece, to facilitate the rapid insertion and removal of paper tubes, thereby improving paper tube conversion efficiency and productivity. However, improving the efficiency of paper tube replacement is only a temporary solution, and the entire device does not utilize the paper tubes sufficiently, making it impossible to evenly wind more waste edges around the paper tubes. Frequent replacement of paper tubes will also lead to reduced production efficiency. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the defects in the prior art. By arranging a reciprocating component to drive the winding core to move, the waste edge is evenly wound on the entire outer circumference of the winding core, thereby improving the utilization rate of the winding core.

[0005] In order to solve the above technical problems, the technical solution of the utility model is a reciprocating waste edge winding device, comprising:

[0006] A winding assembly, the winding assembly comprising a driving device and a winding core;

[0007] The driving device is connected to the winding core and is suitable for driving the winding core to rotate;

[0008] A reciprocating assembly, the reciprocating assembly comprising a second driving device and a reciprocating screw;

[0009] The second driving device is connected to the reciprocating screw to drive the reciprocating screw to rotate;

[0010] The reciprocating screw rod is externally equipped with a connecting component. The reciprocating screw rod is suitable for rotating to drive the connecting component to reciprocate along the axis direction of the reciprocating screw rod. The connecting component is connected to the driving device.

[0011] Furthermore, the reciprocating assembly further includes a guide column, which is fixedly arranged on one side of the reciprocating screw rod, and the connecting component is movably sleeved on the outside of the guide column.

[0012] Furthermore, the connecting component is a transmission sleeve.

[0013] Furthermore, a baffle is provided on one side of the winding core.

[0014] Furthermore, the winding core is an air-inflated shaft.

[0015] Furthermore, the winding device further includes a limiting assembly, which includes a fixing block, a retracting rod, a limiting plate and a fixing assembly;

[0016] The fixing block is connected to the connecting component so as to be adapted to move along with the winding assembly;

[0017] The retractable rod is slidably connected in the fixed block and is limited by the fixed assembly;

[0018] The limiting plate is fixedly connected to the top of the contraction rod, and a cavity penetrating the limiting plate is provided in the limiting plate.

[0019] Furthermore, the fixing assembly includes a through slot formed on the retractable rod and passing through the retractable rod, and a threaded hole formed on the fixing block and passing through the retractable rod;

[0020] The threaded hole is communicated with the through slot, and the threaded hole and the through slot are suitable for passing through the fixing member together.

[0021] Furthermore, the limiting plate is provided with an arc angle.

[0022] Furthermore, an adjustment component is provided in the limiting plate, and the adjustment component includes a pressing plate and a moving part;

[0023] The moving component is connected to the pressing plate so as to be suitable for driving the pressing plate to move longitudinally in the cavity.

[0024] Furthermore, the movable component is an adjusting rod, a threaded hole is provided on the limiting plate, the adjusting rod is threadedly connected in the threaded hole, and the adjusting rod is connected to the pressure plate.

[0025] By adopting the above technical solution, the utility model has the following beneficial effects:

[0026] 1. Through the arrangement of the reciprocating screw and the transmission sleeve, the reciprocating screw rotates under the drive of the second driving device, and at the same time drives the transmission sleeve outside it to make linear motion. The guide column can further prevent the transmission sleeve from rotating on its own. The transmission sleeve realizes the stable reciprocating motion of the winding core, so that the waste edge can completely and evenly cover the surface of the entire winding core, thereby improving the utilization rate of the winding core.

[0027] 2. Through the setting of the air expansion shaft, the air expansion shaft changes its own diameter after being ventilated as a winding core. At this time, the waste edges can be directly wrapped around the outer surface of the air expansion shaft. When the winding is completed, the air inflatable shaft can be deflated to directly remove the waste edges wrapped in a circle. The paper tube can also be put on the outside of the air expansion shaft, and the air expansion shaft and the paper tube can be used as a winding core. After the work is completed, the paper tube and the waste edges wrapped around the outside of the paper tube can be easily and completely removed, which improves the speed of changing the winding core and removing the waste edges, thereby improving production efficiency.

[0028] 3. By setting a baffle, a baffle is set at one end or both ends of the core shaft to prevent problems from occurring when the core is winding the waste edge, causing the waste edge to deviate and leave the range of the core.

[0029] 4. Through the setting of structures such as the limiting plate and the pressing plate, the waste edge passes through the inside of the limiting plate before winding. The limiting plate plays a guiding and limiting role, which can effectively prevent the waste edge from deviating during the winding process. The position-adjustable pressing plate can be adjusted according to the thickness of the waste edge, further ensuring the limiting effect of the waste edge.

[0030] 5. Through the arrangement of the retractable rod and the fixing assembly, the retractable rod can move in the fixed block, thereby changing the height of the limit plate. After adjusting to the required height according to actual conditions, it is fixed by the fixing assembly. By changing the height of the limit plate, the tension of the waste edge can be adjusted to prevent the waste edge from being too loosely wound on the winding core, affecting the quality of the entire winding.

[0041] In order to make the contents of the present invention more clearly understood, the present invention is further described in detail below based on specific embodiments in conjunction with the accompanying drawings.

[0042] Example 1

[0043] like Figure 1-2 As shown, the reciprocating waste edge winding device includes:

[0044] The winding assembly 1 includes a driving device 11 and a winding core 12;

[0045] The driving device is connected to the winding core 12 and is suitable for driving the winding core 12 to rotate;

[0046] Reciprocating assembly 2, the reciprocating assembly 2 includes a driving device 21 and a reciprocating screw 22;

[0047] The second driving device 21 is connected to the reciprocating screw 22 to drive the reciprocating screw 22 to rotate;

[0048] The reciprocating screw rod 22 is equipped with a connecting component on the outside. The reciprocating screw rod 22 is suitable for rotating to drive the connecting component to reciprocate along the axis direction of the reciprocating screw rod 22. The connecting component is connected to the driving device 11.

[0049] like Figure 1 As shown, the reciprocating assembly 2 further includes a guide post 24 , which is fixedly arranged on one side of the reciprocating screw rod 22 , and the connecting component is movably sleeved on the outside of the guide post 24 .

[0050] like Figure 2 As shown, the connecting component is a transmission sleeve 23.

[0051] like Figure 2 As shown, a baffle 13 is provided on one side of the winding core 12 .

[0052] like Figure 2 As shown, the winding core 12 is an air-inflated shaft.

[0053] The working principle of this embodiment is as follows:

[0054] When in use, first place the scrap winding device between the traction machine and the trimming device, then fix the front end of the scrap to the outer surface of the winding core 12. Figure 1 The figure shows the initial position of the equipment, and the front end of the waste edge needs to be fixed on the reel near the baffle 13;

[0055] The drive device 1 11 and the drive device 2 21 are started synchronously. The drive device 1 11 can be a three-phase asynchronous motor, and the drive device 2 21 can be a torque motor.

[0056] After the driving device 11 is started, it drives the winding core 12 and the baffle 13 to rotate together, and starts to continuously reel the waste edge;

[0057] After the driving device 21 is started, it drives the reciprocating screw 22 to rotate. The transmission sleeve 23 assembled on the outside of the reciprocating screw 22 reciprocates along the direction of the thread axis. At the same time, the transmission sleeve 23 drives the driving device 11 connected thereto to move synchronously, thereby driving the winding core 12 to reciprocate. When the winding core 12 reciprocates, the waste edge can be evenly wound around the entire winding core 12 in circles, thereby improving the utilization rate of the winding core 12 and eliminating the need for frequent replacement of the winding core 12.

[0058] It should be noted that the transmission sleeve 23 and the reciprocating screw 22 can be connected by a ball nut, and the reciprocating screw 22 drives the sensing sleeve to reciprocate along the axis of the reciprocating screw 22, which are both existing technologies, and their working principles will not be described in detail here.

[0059] The transmission sleeve 23 is also movably sleeved on the outside of the guide post 24 while moving. The guide post 24 is fixed. The setting of the guide post 24 can prevent the transmission sleeve 23 from rotating under the drive of the reciprocating screw 22, while ensuring the stability of the reciprocating motion of the transmission sleeve 23.

[0060] The setting of the baffle 13 can prevent the waste edge from deviating when it is reciprocatingly wound on the winding core 12, thereby causing the waste edge to escape from the range of the winding core 12. In the figure, the baffle 13 is set at one end close to the driving device 11, and can also be set at the other end of the winding core 12, or a baffle 13 is set in both directions;

[0061] In addition, the winding core 12 can be an air-expanding shaft. When the air-expanding shaft is used as the winding core 12, it can facilitate the removal of the wound waste edge. There are two ways of using it.

[0062] First, inflate the air shaft to increase its diameter, and then wrap the scrap edge directly around the air shaft. After wrapping, deflate the air shaft to reduce its diameter. At this point, the wrapped scrap edge loses the support of the air shaft and can be removed very conveniently.

[0063] Second, place a hollow cylinder such as a paper tube on the outside of the inflatable shaft, inflate the shaft to increase its diameter and support the hollow cylinder. Use the hollow cylinder and the shaft as a whole and wrap the waste edge directly around the hollow cylinder. After wrapping is completed, deflate the shaft. At this time, the hollow cylinder loses the support of the shaft and can be removed together with the waste edge.

[0064] No matter which method is adopted, the effect of facilitating fixing the winding core 12 and removing the winding core 12 and the waste edges thereon can be achieved, thereby greatly reducing manpower and improving overall production efficiency.

[0065] Example 2

[0066] like Figure 3-4 As shown, this embodiment further includes the following structures on the basis of the first embodiment: the winding device further includes a limiting assembly 3, the limiting assembly 3 includes a fixing block 31, a retracting rod 32, a limiting plate 5 and a fixing assembly 4;

[0067] The fixing block 31 is connected to the connecting member so as to be adapted to move along with the winding assembly 1;

[0068] The retracting rod 32 is slidably connected to the fixed block 31 and is limited by the fixing assembly 4;

[0069] The limiting plate 5 is fixedly connected to the top of the contraction rod 32 , and a cavity running through the limiting plate 5 is defined in the limiting plate 5 .

[0070] like Figure 4 As shown, the fixing assembly 4 includes a through slot 41 formed on and passing through the retractable rod 32 and a threaded hole 42 formed on and passing through the fixing block 31;

[0071] The threaded hole 42 communicates with the through slot 41 , and the threaded hole 42 and the through slot 41 are suitable for passing through the fixing member together.

[0072] like Figure 3 As shown, the limiting plate 5 is provided with an arc corner 51 .

[0073] like Figure 3 As shown, an adjustment assembly 6 is provided in the limit plate 5, and the adjustment assembly 6 includes a pressing plate 61 and a moving part;

[0074] The moving component is connected to the pressing plate 61 so as to be suitable for driving the pressing plate 61 to move longitudinally in the cavity.

[0075] like Figure 3 As shown, the movable component is an adjusting rod 62 , a threaded hole 42 is provided on the limiting plate 5 , the adjusting rod 62 is threadedly connected in the threaded hole 42 , and the adjusting rod 62 is connected to the pressing plate 61 .

[0076] The working principle of this embodiment is as follows:

[0077] Before the winding core 12 starts to rewind, the front end of the waste edge is first passed through the cavity in the limiting plate 5, and then fixed at the initial position of the winding core 12 before the rewinding work begins. The limiting plate 5 can limit the position of the waste edge, thus greatly preventing the waste edge from deviating during the rewinding process;

[0078] It should be noted that the limit plate 5 is connected to the retracting rod 32, which is connected to the fixed block 31, and the fixed block 31 is connected to the transmission sleeve 23, so that the limit plate 5 can move synchronously with the movement of the winding core 12, and always play a role in limiting the waste edge being wound;

[0079] The fixed block 31 is connected to the transmission sleeve 23 and can also be movably sleeved on the outside of the guide column 24. The guide column 24 can support the fixed block 31, making the movement of the fixed block 31 more stable.

[0080] Since the thickness of the scrap edge varies according to different actual conditions or product specifications, the position of the pressure plate 61 in the limiting plate 5 can be adjusted to achieve more stable limiting of the scrap edge for scrap edges of different thicknesses, thereby avoiding the situation where the thickness of the scrap edge is much smaller than the size of the cavity, causing the scrap edge to shake in the limiting plate 5 and fail to play a good limiting role;

[0081] When adjusting the pressure plate 61, it is only necessary to rotate the adjusting rod 62. The adjusting rod 62 cooperates with the threaded hole 42 on the limit plate 5 to change the position of the adjusting rod 62. After the position of the adjusting rod 62 is changed, the pressure plate 61 connected thereto will also move within the limit plate 5, thereby achieving the effect of adjusting according to the thickness of the waste edge. It should be noted that the adjusting rod 62 only drives the pressure plate 61 to move within the limit plate 5, but does not rotate. A bearing can be set between the adjusting rod 62 and the pressure plate 61.

[0082] The limit plate 5 is provided with a circular arc corner 51, which can prevent the waste edge from passing through the limit plate 5 and constantly contacting the limit plate 5 during the winding process, thereby causing wear.

[0083] In addition, the limiting plate 5 can also adjust the tension of the scrap edge according to the different positions of the retraction rod 32. In order to prevent the scrap edge from being loosely wound on the winding core 12 due to insufficient tension, a pressure can be applied to the scrap edge by adjusting the height of the retraction rod 32. After the pressure is applied, the tension of the scrap edge changes and the scrap edge can be wound more tightly on the winding core 12.

[0084] The retracting rod 32 itself can slide directly in the fixed block 31, and the height can be adjusted by sliding. After the height is adjusted, the fixing part is passed through the threaded hole 42 on the fixing plate and the through slot 41 on the retracting rod 32 at the same time. The fixing part can be a bolt. The bolt passes through the threaded hole 42 through threaded engagement and then passes through the through slot 41, and finally extends out from the threaded hole 42 at the other end. After extending out, it is fixed by a nut. In this way, the height of the retracting rod 32 is adjusted and fixed, thereby changing the height of the limit plate 5.

[0085] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
