Description

Technical Field

[0001] This utility model relates to the field of cable wrapping technology, specifically an active guide structure for a wrapping machine. Background Technology

[0002] The wrapping machine is a key piece of equipment in cable manufacturing. It is used to tightly wrap the cable core with wrapping material at a specific tension and speed, thereby enhancing the cable's mechanical strength, insulation and anti-interference ability.

[0003] During the operation of the wrapping machine, it is necessary to monitor the tension of the wrapping tape in real time to ensure that the wrapping tape has a constant pitch and appropriate tightness.

[0004] To achieve the above objectives, a tape-drawing and unloading wrapping machine disclosed in Chinese Utility Model Publication No. CN118315137A utilizes a drawer wheel set to draw the wrapping tape and a tension mechanism to apply appropriate tension to the tape reel in a coordinated manner. The drawer wheel set includes an upper drawer wheel and a lower drawer wheel, which are rotatably connected to the wrapping seat. The upper and lower drawer wheels are vertically aligned and parallel to each other. After the wrapping tape passes around the exit pulley, it passes between the upper and lower drawer wheels. Under the combined action of the upper and lower drawer wheels, the wrapping tape is driven to move, thereby drawing the wrapping tape. Essentially, the wrapping tape is drawn using a circular-on-circular structure formed by the upper and lower drawer wheels.

[0005] The aforementioned upper and lower take-up wheels are arranged vertically relative to the rotation axis around the packing seat. When rotating at high speed around the packing seat, the centrifugal force will cause the circular pressing structure formed by the upper and lower take-up wheels to become unstable, which will affect the stability of the packing tape take-up and cause tension fluctuations in the packing tape. Summary of the Invention

[0006] The present invention aims to overcome the above-mentioned deficiencies of the prior art and provides an active guide belt structure for a wrapping machine, the technical solution of which is as follows.

[0007] An active guide belt structure for a wrapping machine includes a wrapping seat with a rotating shaft arranged horizontally, a wrapping arm at the left end of the wrapping seat, a wrapping wheel on the wrapping arm, a wrapping channel extending to the left end at the right end of the wrapping seat, and a guide belt wheel assembly located at the left end of the wrapping channel in the wrapping seat. The guide belt wheel assembly includes a pressure wheel and a take-up wheel arranged sequentially from left to right. The axial directions of the pressure wheel and the take-up wheel are both arranged in the front-back direction, and the pressure wheel and the take-up wheel form a round-to-round fit.

[0008] In one improvement, a stainless steel spring plunger is also provided at the left end of the wrapping seat, which is axially arranged in the horizontal direction. The stainless steel spring plunger is threadedly connected to the wrapping seat to realize axial movement adjustment. The right end of the stainless steel spring plunger elastically abuts against the pressure roller, so that the pressure roller abuts against the take-up roller in the horizontal direction.

[0009] In one improvement, the wrapping seat is further provided with a tensioning roller arranged axially in the front-back direction. The tensioning roller is located between the guide pulley group and the left end of the wrapping channel, and the lower edge of the tensioning roller is flush with the center line of the wrapping channel.

[0010] In one improvement, the upper end of the wrapping base is also provided with an inductive roller arranged axially in the front-back direction, and an inductive proximity sensor for detecting whether the inductive roller is rotating.

[0011] Compared with the prior art, the present invention has the following advantages: the pressure roller and the take-up roller in the guide roller assembly are arranged horizontally side by side. When rotating at high speed around the packing seat, the centrifugal force has little impact on the circular contact formed by the pressure roller and the take-up roller, thus ensuring the stability of the guide roller assembly driving the packing belt; in addition, the belt breakage detection function can be realized through the induction roller, which optimizes the overall structure.

[0012] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

[0013] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0014] Please see Figure 1 As shown, in one embodiment, the present invention provides an active guide belt structure for a wrapping machine, including a wrapping seat 1 with the rotating shaft arranged in a horizontal direction, a wrapping arm 2 at the left end of the wrapping seat 1, a wrapping wheel 3 on the wrapping arm 2, a wrapping belt channel 4 extending to the left end at the right end of the wrapping seat 1, and a guide belt wheel assembly located at the left end of the wrapping belt channel 4 in the wrapping seat 1. The guide belt wheel assembly includes a pressure wheel 5 and a take-up wheel 6 arranged sequentially from left to right. The axial directions of the pressure wheel 5 and the take-up wheel 6 are both arranged in the front-back direction, and the pressure wheel 5 and the take-up wheel 6 form a round-to-round fit.

[0015] In the above embodiment, the wrapping base 1 also has a wire-passing hole 7 arranged along the rotation axis. The cable 8 passes through the wire-passing hole 7 from the left end of the wrapping base 1, and the wrapping tape 9 is introduced from the right end of the wrapping tape channel 4. Then, it is introduced downward along the upper edge of the take-up wheel 6 between the pressure wheel 5 and the take-up wheel 6. After passing around the left side of the pressure wheel 5, it is led out upward, and then passes around the wrapping wheel 3 before being wound around the cable. The cable is pulled to the right at a uniform speed, and the take-up wheel 6 rotates actively under the drive of the transmission structure to actively take up the wrapping tape. The wrapping base 1 rotates rapidly, thereby continuously winding the wrapping tape 9 around the cable 8.

[0016] Since the pressure roller 5 and the take-up roller 6 in the pulley assembly are horizontally arranged side by side, when they rotate at high speed around the packing seat, the centrifugal force has little effect on the circular contact between the pressure roller 5 and the take-up roller 6, thus ensuring the stability of the pulley assembly driving the packing belt. Especially when the mass difference between the pressure roller 5 and the take-up roller 6 is small, the centrifugal force will have a minimal impact on the circular contact between the pressure roller 5 and the take-up roller 6.

[0017] Therefore, when the rotational speed of the take-up wheel 6 is just matched with the traction speed of the cable, this invention can more easily achieve zero tension on the wrapping tape drawn from the wrapping wheel 3.

[0018] In a preferred embodiment, a stainless steel spring plunger 11, axially and horizontally positioned, is also provided at the left end of the wrapping seat 1. The stainless steel spring plunger 11 is threadedly connected to the wrapping seat 1 to achieve axial movement adjustment. The right end of the stainless steel spring plunger 11 elastically abuts against the pressure roller 5, causing the pressure roller 5 to press against the take-up roller 6 horizontally. Obviously, rotating the stainless steel spring plunger 11 can adjust its axial movement, meaning the tension of the pressure roller 5 and the take-up roller 6 can be adjusted using the stainless steel spring plunger 11 to prevent the strap from slipping. Of course, the contact point between the stainless steel spring plunger 11 and the pressure roller 5 does not coincide with the position where the strap wraps around the pressure roller 5. For example, the stainless steel spring plunger 11 may be located at the edge of the pressure roller 5, while the strap wraps around the middle of the pressure roller 5.

[0019] In a preferred embodiment, the wrapping seat 1 is further provided with a tension roller 12 arranged axially in the front-rear direction. The tension roller 12 is located between the guide roller assembly and the left end of the wrapping channel 4, and the lower edge of the tension roller 12 is flush with the center line of the wrapping channel 4. After the wrapping tape 9 is led out from the left end of the wrapping channel 4, it first wraps around the lower edge of the tension roller 12 and is then guided to the take-up roller 6.

[0020] In a preferred embodiment, the upper end of the wrapping base 1 is further provided with an inductive roller 13 axially arranged in the front-back direction, and an inductive proximity sensor for detecting whether the inductive roller 13 is rotating. Those skilled in the art will understand that the inductive proximity sensor detects metal through electromagnetic induction, and the inductive roller 13 only needs to contain a metal component that cooperates with the inductive proximity sensor. When the wrapping tape breaks, the inductive roller 13 stops rotating, the position of the metal component no longer changes, and the inductive proximity sensor outputs a signal to trigger a stop alarm.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
