Description

Technical Field

[0001] This utility model relates to a packing strap processing equipment, and more particularly to a packing strap winding device. Background Technology

[0002] Current strapping rewinding devices mainly consist of a rewinding drum, a telescopic rod, guide wheels, and a pressure plate. The rewinding drum rotates to wind the strapping. The guide wheels and pressure plate are mounted on the telescopic rod and move back and forth with the extension and retraction of the rod during the rewinding process, guiding and arranging the strapping. This allows the strapping to pass through the guide wheels and pressure plate sequentially, arranging and winding along the width of the rewinding drum. Simultaneously, the pressure plate must adhere to the surface of the strapping on the rewinding drum during the rewinding process, ensuring that the strapping is directly pulled onto the rewinding drum after extending from the pressure plate. This prevents the strapping from bending or jamming during rewinding and also allows for a tighter winding of the strapping.

[0003] The problem with existing strapping rewinding devices is that, to ensure a tight fit between the pressure plate and the strapping during rewinding, manufacturers apply pressure to the pressure plate towards the strapping using springs or push rods. However, because the strapping expands outwards continuously during rewinding, this method cannot maintain a constant pressure on the pressure plate throughout the process. This results in the pressure plate vibrating and shifting in the early stages of rewinding due to insufficient pressure, and in the later stages, excessive pressure preventing the pressure plate from moving laterally. To address this deficiency, manufacturers currently install the telescopic rod and pressure device together on a lateral movement mechanism, moving it radially along the rewinding drum during rewinding. This keeps the relative positions of the pressure plate, pressure device, and strapping on the rewinding drum surface constant, ensuring effective compression and rewinding. However, this approach increases equipment costs and overall dimensions.

[0004] Therefore, existing strapping tape winding devices suffer from high equipment costs. Utility Model Content

[0005] The purpose of this invention is to provide a packing tape winding device that can reduce equipment costs while ensuring winding efficiency.

[0006] The technical solution of this utility model is as follows: A packing strap winding device includes a winding drum, a swing plate on one side of the winding drum, a drive assembly connected to the inner side of the swing plate, a telescopic rod in the middle of the swing plate, the telescopic rod and the swing plate being nested and slidably connected, the end of the telescopic rod passing through the swing plate and connected to a guide plate, a guide wheel and a pressing assembly respectively connected to the guide plate, a pressure rod on the outer side of the pressing assembly, and the end of the pressure rod connected to the swing plate; the drive assembly includes a sleeve connected to the inner side of the swing plate, an adjusting plate on the outer side of the sleeve, a steel wire rope connected to the outer end of the adjusting plate, a tension spring connected to the middle of the steel wire rope, and a traction part connected to the end of the steel wire rope.

[0007] In the aforementioned packing tape winding device, the pressing assembly includes a pressing plate rotatably connected to a guide plate, a limiting sleeve detachably connected to the pressing plate, an opening for the packing tape to pass through is formed between the pressing plate and the limiting sleeve, and a positioning pin is connected to the lower end of the pressing plate.

[0008] In the aforementioned packing tape winding device, the two ends of the positioning pin are connected to the pressing plate via connecting plate screws.

[0009] In the aforementioned packing strap winding device, the middle part of the pressing plate is detachably connected to a positioning component for fitting the packing strap and limiting the angle of the pressing plate.

[0010] In the aforementioned packing tape winding device, the traction unit is an electric winch.

[0011] In the aforementioned packing tape winding device, the sleeve and the adjusting plate are nested together, with one end of the sleeve passing through the adjusting plate and connected to a fixing nut. The fixing nut is used to compress and fix the sleeve and the adjusting plate after tightening.

[0012] Compared with the prior art, this utility model has the following characteristics:

[0013] (1) The present invention uses the structure of the swing plate and the pressure rod to make the pressure rod rotate with the change of the packing strap winding position during the pressure application process, thereby ensuring the stable fit of the pressure rod to the pressing component; by limiting the structure of the drive component, the traction part can pull the wire rope with the change of the packing strap winding position, so that the tension spring can maintain a specific tension state when the swing plate rotates to different positions, thereby using the cooperation of the tension spring and the pressure rod to apply a constant extrusion force to the pressing component, ensuring the winding effect of the present invention; and with the above cooperation, the present invention does not need to drive the telescopic rod, drive component and pressing component to move as a whole compared with the existing winding device, effectively reducing the equipment cost of the device;

[0014] (2) By limiting the structure of the pressing component, on the one hand, the pressing plate can rotate with the change of the winding position of the packing strap, thereby ensuring its winding stability; on the other hand, the cooperation of the positioning parts, positioning pins and connecting plates can prevent the pressing plate and the surface of the packing strap from direct contact, thereby improving the lateral stability of the pressing component and preventing wear on the surface of the packing strap after lateral movement.

[0015] Therefore, this invention can reduce the equipment cost of the device while ensuring the winding effect. Attached Figure Description

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0022] Example. A packing tape winding device, configured as follows: Figure 1 As shown, the assembly includes a winding drum 1, a swing plate 2 on one side of the winding drum 1, the inner side of the swing plate 2 being rotatably connected to the winding frame, a drive assembly connected to the inner side of the swing plate 2, a telescopic rod 3 in the middle of the swing plate 2, the telescopic rod 3 and the swing plate 2 being nested and slidably connected, the end of the telescopic rod 3 passing through the swing plate 2 and connected to a guide plate 4, a guide wheel 5 and a pressing assembly connected to the guide plate 4 respectively, a pressing rod 6 on the outer side of the pressing assembly, the end of the pressing rod 6 being connected to the swing plate 2; the drive assembly includes a sleeve 7 connected to the inner side of the swing plate 2, one end of the sleeve 7 being fastened to the swing plate 2 via a stepped groove, the other side of the sleeve 7 passing through the swing plate 2 and an outer mounting plate in sequence and connected to an adjusting plate 8, a steel wire rope 9 connected to the outer end of the adjusting plate 8, a tension spring 10 connected to the middle of the steel wire rope 9, and a traction part 11 connected to the end of the steel wire rope 9.

[0023] The sleeve 7 and the outer mounting plate are rotatably connected to each other, and the telescopic rod 3 extends through the sleeve 7 to the outside of the swing plate 2.

[0024] The sleeve 7 is provided with the pressing assembly, which includes a pressing plate 12 rotatably connected to the guide plate 4. A limiting sleeve 13 is detachably connected to the pressing plate 12. An opening for the packing strap to pass through is formed between the pressing plate 12 and the limiting sleeve 13. A positioning pin 14 is connected to the lower end of the pressing plate 12.

[0025] The two ends of the positioning pin 14 are connected to the pressing plate 12 by screws on the connecting plate 15. The positioning pin 14 is used to limit the extension angle of the packing strap to avoid friction damage caused by excessive bending of the packing strap.

[0026] The middle part of the pressing plate 12 is detachably connected to a positioning element 16 for attaching the packing strap and limiting the angle of the pressing plate 12.

[0027] The traction unit 11 is an electric winch.

[0028] The sleeve 7 and the adjusting plate 8 are nested together. One end of the sleeve 7 passes through the adjusting plate 8 and is connected to a fixing nut 17. The fixing nut 17 is used to press and fix the sleeve 7 and the adjusting plate 8 after tightening.

[0029] The working principle of this utility model is as follows: In use, the telescopic rod 3 drives the guide plate 4 and guide wheel 5 to reciprocate horizontally along the width of the winding drum 1. The guide wheel 5 and guide plate 4 guide the packing strap, allowing it to pass sequentially through the guide wheel 5, guide plate 4, and positioning pin 14 before entering the winding drum 1. The winding drum 1 then rotates to wind up the packing strap. During the winding process, the traction unit 11, through the cooperation of the wire rope 9 and tension spring 10, pulls the adjusting plate 8, keeping the tension spring 10 in a stretched state. This allows the tension spring 10 to apply a continuous traction force to the pressing plate 12 through the cooperation of the adjusting plate 8 and pressure rod 6. Under this traction force, the pressing plate 12, via the positioning member 16, adheres to the packing strap on the surface of the winding drum 1, achieving the winding effect.

[0030] As the packing tape on the surface of the winding drum 1 expands outward with the increase of winding amount, the pressing plate 12 and the pressing rod 6 rotate accordingly and drive the tension spring 10 to move laterally. At this time, the traction part 11 can keep the tension spring 10 in a stable tension state by extending and retracting the wire rope 9, so that the pressing force of the pressing rod 6 on the pressing plate 12 can be controlled within a constant range, ensuring its pressing and limiting effect.
