Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of strapping machine, specifically disclose a strapping machine with pull back silk containing cavity. BACKGROUND

[0002] In the construction industry, strapping machine is a commonly used tool, used to tie the wire on the reinforcement to fix the structure. This device is essential to ensure the stability and safety of the building structure. The use of strapping machine not only improves the construction efficiency, but also helps to reduce the labor intensity of workers when fixing the reinforcement.

[0003] The existing strapping machine is usually composed of multiple units, including feeding unit, curling guide unit, cutting unit, strapping unit and containing unit, etc. These units work together to complete the feeding, guiding, curling, holding, cutting, twisting and releasing of wire. The feeding unit is responsible for feeding the wire to the desired position, the curling guide unit guides the wire to curl around the reinforcement, the cutting unit is used to cut off the excess wire, and the strapping unit is responsible for twisting and fixing the wire on the reinforcement, and the containing unit is used to store the wire to ensure its orderly supply.

[0004] In order to reduce the consumption of wire, the existing strapping machine will pull back the wire to the steel bar by the reverse rotation of the feeding gear after the wire is fed to the steel bar in a circle, so as to tighten the steel bar and save the amount of wire. However, this design has problems in actual operation. Because the wire pulled back downward will cause extrusion or collision to the wire in the wire disc storage, which may cause the wire to bend, jam or be stuck in the wire slot. In order to solve this problem, the existing strapping machine increases the circular radius of the wire disc storage to accommodate the pulled back wire, but in actual use, this method cannot well solve the problems of bending, jamming or sticking of the pulled back wire. Therefore, the existing strapping machine still has room for improvement in improving work efficiency and reducing material waste. SUMMARY

[0005] For the existing structure of accommodating the pulled back wire by increasing the circular radius of the wire disc storage, it is still difficult to solve the problems of bending, jamming or sticking of the pulled back wire. After research, it is found that this is because the pulled back wire has space to accommodate in the wire disc storage with increased circular radius, but the wire will disturb the wire on the wire disc during the process of retreating. This disturbance to the wire will cause the wire to move back and forth, thus easily causing the overlapping of each coil of wire, so it is difficult to solve the problems of bending, jamming or sticking of the pulled back wire.

DETAILED DESCRIPTION

[0028] In order to make the above -mentioned purpose, feature and advantage of the utility model more obvious and easy to understand, the utility model is further explained in detail below with the drawings and specific embodiment.

[0029] A kind of bundling machine with the silk line that pulls back the accommodation cavity, refer to Figures 1-4, including the shell 1 and provided with the wire feeding mechanism 2 and the wire reel compartment 3 in the shell 1. The wire reel compartment 3, the wire reel compartment 3 specifically includes the wire reel compartment body 31 and the wire reel compartment cover 32 installed on the wire reel compartment body 31, the inner wall of the wire reel compartment body 31 and the inner wall of the wire reel compartment cover 32 are smoothly connected, the wire reel compartment 3 is provided with a wire reel groove 34 for accommodating the wire reel 4, the wire reel compartment 3 is used for storing the wire reel 4, and the wire reel compartment 3 is provided with a wire outlet 33 on one side of the top. The wire feeding mechanism 2 is located above the wire outlet 33, and the wire feeding mechanism 2 is used for feeding the wire upward. The side of the wire reel compartment 3 towards the wire outlet 33 is provided with a J-shaped accommodating cavity 35, the accommodating cavity 35 is communicated with the wire reel groove 34 and the wire feeding mechanism 2, and the J-shaped accommodating cavity 35 is arranged around the outer periphery of the wire reel groove 34.

[0030] By designing the accommodating cavity 35 on one side of the wire reel compartment 3, when the wire feeding mechanism 2 reverses to pull back the wire, the accommodating cavity 35 provides a storage position for the pulled-back wire. Compared with the wire reel compartment 3 with a circular accommodating space in the prior art, the accommodating space is designed in the shape of a hook in the present scheme, so that the pulled-back wire moves to one side of the wire reel compartment 3, which can maximize the reduction of the influence of the existing winding wire on the wire reel on the pulled-back wire, more effectively solves the problems of bending, jamming or sticking of the pulled-back wire, and helps the smooth re-feeding of the wire, thereby improving the smoothness of wire feeding.

[0031] The J-shaped accommodating cavity described in the present scheme can also be called a fishhook type or a bent hook type, and the direction of the hook part can be determined according to the position of the wire reel groove 34 of the wire reel compartment 3, and the direction of the hook part is not limited.

[0032] Specifically, referring to Figure 3 , the accommodating cavity 35 includes a straight rod part 351 and a bent hook part 352, the straight rod part 351 is communicated with the wire outlet 33 and extends to the wire feeding mechanism 2, and the bent hook part 352 surrounds one side of the outer periphery of the wire reel groove 34. The width of the bent hook part 352 near the beginning of the wire outlet 33 is the largest, the ratio of the maximum width of the accommodating cavity 35 to the diameter of the wire reel groove 34 is 0.1-0.4, and the optimal ratio is 0.3. If the ratio is too small, the space of the accommodating cavity 35 is not enough for the pulled-back wire to be placed, and if the ratio is too large, it is not conducive to the miniaturization of the equipment; the width of the end of the bent hook part 352 is the smallest and is arc-shaped to the edge of the wire reel groove 34. By adopting the above design, the wire is not easy to disturb the wire in the wire reel 4 during the pulling-back process, and when the wire feeding mechanism 2 is rotated forward, the previously pulled-back wire can be fed upward first, thereby maximizing the avoidance of the wire feeding jamming problem.

[0033] Of course, in other embodiments, the shape of the accommodating cavity 35 can also be U-shaped or C-shaped, and such accommodating cavities 35 which are not circular can also achieve good effects of preventing wire feeding jamming.

[0034] As a preferred scheme, referring to Figure 4, the arc-shaped baffle 36 is located at the outer peripheral edge of the wire disc groove 34 on the side beyond the wire outlet 33. By arranging the arc-shaped baffle 36, the outer side part of the wire disc 4 arranged in the wire disc groove 34 is covered, so that the wire of the wire disc 4 away from the wire outlet position is not scattered outward by the traction of the back-pulling thin wire, thereby better avoiding the problem of wire winding. In addition, the arc-shaped baffle 36 can include a baffle part 361 and an arc-shaped protruding part 362 arranged on the baffle part 361, the arc-shaped protruding part 362 is in contact with the wire of the wire disc 4, and can play a role in reducing the abrasion of the wire.

[0035] As a preferred solution, with reference to Figure 4 , the supporting ribs 37 are arranged on the accommodation cavity 35 in intervals, the top end of the supporting rib 37 is flush with the inner surface of the wire disc 4, so that the wire can be supported by the supporting rib 37 after being back-pulled, the radial movement space of the wire is reduced, thereby better avoiding the problem of wire winding. In addition, the top end of the supporting rib 37 is arranged in an arc surface, which also plays a role in reducing the abrasion of the wire.

[0036] The above describes the technical solutions provided by the utility model in detail, and the principles and implementation manners of the utility model are described by applying specific examples; the above description of the embodiments is only used to help understand the method of the utility model and its core idea; meanwhile, for those skilled in the art, according to the idea of the utility model, the specific implementation manners and application range will be changed, and the above description of the specification should not be understood as the limitation of the utility model.
