Description

Technical Field

[0001] This utility model relates to the technical field of sleeve processing equipment, and in particular to a stable sleeve cutting structure. Background Technology

[0002] Currently, the process of cutting wire harnesses into sleeves in the market simply involves adding auxiliary structures such as a sleeve fixing block at the inlet, a receiving frame at the outlet, and a protective cover at the outlet to the original sleeve cutting machine. However, these structures only improve mechanical problems that may occur during sleeve cutting and do not take into account factors such as unstable sleeve feeding during the feeding process (the sleeve may swing before cutting) and static electricity generated by friction. Therefore, instability in the sleeve feeding process (inability to guide the sleeve for stable feeding) and product blockage at the discharge port due to static electricity and other factors may lead to defects such as out-of-tolerance dimensions or tilted cuts in the cut sleeves, failing to guarantee the quality of the cut sleeves.

[0026] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0027] like Figures 1 to 3 As shown, a stable sleeve cutting structure includes a feeding mechanism 10, a guide plate 20, a cutting assembly 30, and an antistatic assembly. The feeding mechanism 10 includes a body 11, a mounting rod 12, and a feeding roller assembly 13. The mounting rod 12 is located at the beginning of the body 11 and is used to mount a sleeve guide wheel 121. The sleeve guide wheel 121 is preferably mounted on the mounting rod 12 with a small range of lateral movement. For example, by fixing a pair of limiting blocks (not shown) at the middle position of the mounting rod 12 with a gap, the sleeve guide wheel 121 can only move laterally within the gap between the pair of limiting blocks, and its range of movement is small. The sleeve guide wheel 121 can pre-guide the sleeve 100 before it enters the guide hole 21 of the guide plate 20. Its lateral movement characteristics can also be applied to guide holes at different positions. 21. The end of the machine body 11 is provided with a feeding plate 111 with an inclined structure. The feeding roller assembly 13 is provided at the end of the machine body 11 for clamping and feeding the sleeve 100. The guide plate 20 is provided on the side of the machine body 11 near the feeding roller assembly 13 and is provided with a plurality of guide holes 21 for the sleeve 100 to pass through. The plurality of guide holes 21 have different widths for guiding the sleeves 100 with different outer diameters. The cutting assembly 30 is provided at the end of the machine body 11 for cutting the sleeves 100 fed by the feeding roller assembly 13. The static elimination assembly includes a mounting frame 41 and an ion air bar 42. The mounting frame 41 is provided at the end of the machine body 11. The ion air bar 42 is provided on the mounting frame 41 near the feeding plate 111 and can be used on the cut sleeves 100.

[0028] In this utility model, it is preferable to cut a continuously fed sleeve 100. The sleeve 100 is guided upward from its storage device by the sleeve guide wheel 121, passes through the guide hole 21 of the guide plate 20, and is then clamped and fed to the cutting component 30 by the feeding roller assembly 13. The cutting component 30 cuts off the end of the sleeve 100 to form a product (short sleeve). When the product leaves the cutting component 30, it is de-staticated by the action of the ion air bar 42 and then slides down the unloading plate 111 to the corresponding receiving device.

[0029] The sleeve 100 is moved by the feeding roller assembly 13, which clamps the sleeve 100 together with a pair of feeding rollers and drives the sleeve 100 to move by friction while rotating relative to each other. The pair of feeding rollers can be driven by a motor to rotate relative to each other. The static electricity generated by the sleeve 100 during friction with the feeding rollers can be eliminated by the action of the ion air bar 42 to ensure that the product formed after cutting is free of static electricity and to achieve stable feeding. The cutting assembly 30 can have a conventional cutting opening 31, a cutting blade and a drive unit. The cutting opening 31 is located near the feeding roller assembly 13 for the sleeve 100 to extend into it. The cutting blade and the drive unit can be located in the inner shell structure of the machine body 11. The drive unit is preferably a lifting cylinder. The cutting blade is set at the output end of the drive unit and can be driven to rise and extend into the cutting opening 31 to cut off the end of the sleeve 100 located therein to form the product (short sleeve).

[0030] This invention allows the sleeve 100 to be fed and cut perpendicularly to the feeding roller assembly 13 and the cutting assembly 30 via the guide hole 21 on the guide plate 20. After being guided, the sleeve 100 enters the cutting assembly in a stable state (rather than swinging or shaking), ensuring that no oblique cuts appear on the product during the cutting process, thus guaranteeing stable product quality. Furthermore, the static electricity generated on the product after friction by the feeding roller assembly 13 can be eliminated by the ion air bar 42, preventing static electricity from adsorbing onto the unloading plate 111 and blocking the cutting opening 31, or causing static adsorption between multiple products that makes them difficult to separate, thus achieving stable feeding. Moreover, the guide plate 20 has multiple guide holes of different sizes, such as first guide holes 211 and second guide holes 212 of different sizes, which can be used for guiding and cutting sleeves of different outer diameters, thus having a wider range of applications and better applicability.

[0031] Preferably, a plurality of slots 200 are provided at the lower end of the guide plate 20, and the guide hole 21 is formed by the combination of the slots 200 and the machine body 11, which facilitates the forming of the guide hole 21.

[0032] Furthermore, the vertical cross-section of the slot 200 is square, and multiple slots 200 have different widths. The square slots 200 of different widths can form first guide holes 211, second guide holes 212, etc. of different sizes to meet the needs of sleeves with different outer diameters. For example, the width of the slot 200 can be multiple different widths from 0.8mm to 2mm. The square cross-section of the slot 200 is more conducive to the formation of guide holes 21 after the lower end face of the guide plate 20 abuts against the upper end face of the body 11, and the abutting state of the two can ensure the installation stability of the guide plate 20. Moreover, an arc surface structure can be formed at the upper end of the slot 200, which can better match the structure of the sleeve 100.

[0033] Preferably, the guide plate 20 is provided with a vertical clearance opening 201 that penetrates its body. The feeding roller assembly 13 is embedded in the clearance opening 201, and the guide holes 21 extend to both sides and are located on opposite sides of the feeding roller assembly 13. That is, after the sleeve 100 is fed by friction by the feeding roller assembly 13 to the cutting assembly 30 (cutting opening 31), it can still be guided to the correct position by the guide holes 21 to ensure that it is cut perpendicular to the cutting opening 31, thereby ensuring the cutting quality of the product and more effectively avoiding the occurrence of skew cutting.

[0034] In one embodiment, the guide plate 20 is provided with a pair of oblong holes 202, and the feeding mechanism 10 (i.e., the machine body 11) is provided with a locking groove (not shown). The guide plate 20 is fixed to the machine body 11 by bolts passing through the oblong holes 202 and extending into the locking groove. The oblong holes 202 facilitate fine-tuning of the installation position of the guide plate 20. In other embodiments, magnets can be provided on the sides of the guide plate 20 and the machine body 11 that abut against each other, and the guide plate 20 can be positioned on the machine body 11 by magnetic attraction. This method makes the installation and removal of the guide plate 20 more convenient.

[0035] like Figure 4 As shown, in the static elimination assembly, its mounting frame 41 includes a pair of mounting plates 411. The mounting plate 411 includes a backing plate 4112 and a support plate 4111 perpendicularly connected to the backing plate 4112. The backing plate 4112 is fixed to the body 11 of the feeding mechanism 10 by bolts. The support plate 4111 is provided with a slot 410. The ion air bar 42 is embedded in the slot 410. By setting the pair of mounting plates 411 on opposite sides of the unloading plate 111, the ion air bar 42 can be supported and positioned closer to the cutting opening 31, which is more conducive to the static elimination treatment of the product. The setting of the slot 410 can ensure the stability of the ion air bar 42 on the mounting frame 41.

[0036] Furthermore, an auxiliary plate 4113 is provided on the side of the groove 410 on the support plate 4111. The auxiliary plate 4113 is provided with a locking hole, and a bolt 412 for fixing the ion air bar 42 is provided in the locking hole. The stability of the ion air bar 42 can be ensured by the bolt 412 abutting against the outer wall of the ion air bar 42.

[0037] Combination Figure 1 and Figure 5 As shown, the air pipe 420 of the ion bar 42 is equipped with a regulating valve 43, which is used to adjust the airflow of the ion bar 42. Since this utility model can be used to cut sleeves with different outer diameters, the different outer diameters or lengths of the cut products can lead to different product quality. In order to ensure the static elimination effect without affecting the product feeding (e.g., a larger airflow of the ion bar 42 affects the feeding of smaller products), the airflow of the ion bar 42 can be controlled by adjusting the regulating valve 43 to control the flow rate of the gas in the air pipe 420. Furthermore, to achieve precise control, the preferred structure of the regulating valve 43 includes a base 431 and a knob 432. The base 431 has a transverse hole 4310 penetrating its body and a threaded hole 4311 communicating with the transverse hole 4310. The knob 432 has an external thread 4321. The transverse hole 4310 is for the air tube 420 to pass through, so that the air tube 420 can be guaranteed to have a better overall sealing effect. The end of the knob 432 extends into the threaded hole 4311 and squeezes the air tube 420 to change the air passage cross section of the air tube 420 to adjust the airflow size at the output end of the ion fan bar 42. By matching the external thread 4321 of the knob 432 with the threaded hole 4311, the depth of the end of the knob 432 extending into the transverse hole 4310 can be adjusted more precisely, thus the airflow size can be adjusted more precisely.

[0038] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
