Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary facilities for balers, in particular to a wire placing rack for a baler. Background Art

[0002] A baler is used to bale loose materials such as waste paper, waste plastics, and straw into relatively regular block-shaped bodies with a larger density, so as to reduce the volume of the materials and facilitate transportation and storage. It mainly compresses the materials input into the material extrusion cavity through a jack. After being compressed into a block-shaped body, steel wires are used for bundling, and a bale is formed and output after bundling. Based on the fact that most of the bales produced are large bales with a side length of 1 m or more, the steel wire used for bundling is at least about 5 mm in diameter to meet the bundling force requirement. As Figure 4 shown, the steel wire is placed on the wire placing rack in the form of a wire coil. Based on the fact that the baler actively uses the wire, passive wire release is formed at the wire placing rack. The released steel wire is turned into an approximately horizontal state by the upper guiding device and then guided to the baler for use.

[0003] Among them, the wire placing rack mainly includes a base and a cage-shaped structure on the base for positioning the wire coil. Based on the operation requirements such as sleeving and placing the wire coil on the wire placing rack, it usually relies on its own weight to lean against the ground without bolt fixation. During actual operation, based on the fact that the steel wire on the wire placing rack is originally in a coiled state, it will roughly form a spiral posture when released. When the spiral steel wire reaches the upper guiding device, due to the guiding and restricting action of the guiding device, the spiral part will swing laterally. Such swinging will cause frequent collisions between the steel wire and the cage-shaped structure in the middle of the wire placing rack. Such collisions will drive the wire placing rack to lift. Especially when there is less steel wire on the wire placing rack, this lifting action will be very obvious. After frequent lifting actions, the wire placing rack will shift to a certain extent. After shifting and then being rigidly pulled in the return direction of the spiral part, the wire placing rack has the risk of tipping over. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a wire placing rack for a baler that is less affected by the swinging of the steel wire and has good use stability.

[0005] To solve the above technical problem, the technical solution of the utility model is: a wire placing rack for a baler, including a base, the top of the base is provided with a bearing surface for placing the wire coil, and at least three positioning steel bars located inside the wire coil are circumferentially arranged on the base; the positioning steel bar includes a free section higher than the bearing surface, the upper end of the free section is bent with a floating connection section, the floating connection section is arranged in the converging direction, and a hook section facing the free section is bent on the floating connection section, and the hook section and the floating connection section form a floating connection slideway; a floating connection ring is commonly installed on the floating connection slideway.

[0006] As a preferred technical solution, the base includes two main ribs arranged in a cross shape, and the top surfaces of the main ribs together form the bearing surface; reinforcing ribs are fixedly connected between the adjacent ends of the two main ribs respectively.

[0007] As a preferred technical solution, the positioning steel bar includes a fixed section lower than the bearing surface, and the fixed section bends towards the reinforcing rib and is fixedly connected to the inner side surface of the reinforcing rib.

[0008] As a preferred technical solution, the floating connection ring and the floating connection slideway are in clearance fit.

[0009] As a preferred technical solution, there are four positioning steel bars.

[0010] Due to the adoption of the above technical solution, a wire feeding rack for a baling machine includes a base. The top of the base is provided with a bearing surface for placing a steel wire coil, and at least three positioning steel bars located inside the steel wire coil are circumferentially arranged on the base; the positioning steel bar includes a free section higher than the bearing surface, a floating connection section is bent at the upper end of the free section, the floating connection section is arranged towards the converging direction, and a hook section facing the free section is bent on the floating connection section. The hook section and the floating connection section form a floating connection slideway; a floating connection ring is jointly sleeved on the floating connection slideway. In the present utility model, a cage-shaped structure for positioning the steel wire coil is formed by multiple positioning steel bars. The upper section of the positioning steel bar is floating, and a closed cage-shaped structure is formed by the floating connection slideway and the floating connection ring at the upper end, and it is not easy to be hooked with the steel wire. When the steel wire swings during the wire feeding process, the free section affected by the collision of the steel wire can form an adaptive retreat by relying on its own floating. The collision between the steel wire and the positioning steel bar is significantly reduced, and the force of the steel wire collision is not easy to be transmitted to the position of the base. The present utility model is less affected by the swing of the steel wire and has good use stability. Description of the Drawings

Specific embodiments

[0017] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments. In the following detailed description, only some exemplary embodiments of the present utility model are described by way of illustration. It is understood that those of ordinary skill in the art can recognize that the described embodiments can be modified in various different ways without departing from the spirit and scope of the present utility model. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of protection of the claims.

[0018] As Figure 1 、 Figure 2 and Figure 3 Collectively shown, the wire releasing rack for a strapping machine includes a base 1, and a bearing surface 111 for placing the steel wire coil 91 is provided on the top of the base 1. In this embodiment, the base 1 includes two main reinforcements 11 arranged in a cross shape, and the top surfaces of the main reinforcements 11 together form the bearing surface 111; stiffening ribs 12 are fixedly connected between adjacent ends of the two main reinforcements 11 respectively, and the base 1 with good stiffness and a certain weight is formed by such a simple structure. Among them, both the main reinforcement 11 and the stiffening rib 12 can be made of section steel such as channel steel and angle steel.

[0019] At least three positioning steel bars 2 are circumferentially arranged on the base 1 inside the steel wire coil 91, and the positioning steel bars 2 together form a cage structure for positioning the steel wire coil 91. Based on the structural setting of the base 1 in this embodiment, this embodiment shows that four positioning steel bars 2 are provided. Specifically, the positioning steel bar 2 includes a fixed section 21 lower than the bearing surface 111, and the fixed section 21 bends towards the stiffening rib 12 and is fixedly connected to the inner side surface of the stiffening rib 12, that is, one positioning steel bar 2 is fixedly arranged at each stiffening rib 12.

[0020] The positioning steel bar 2 includes a free section 22 higher than the bearing surface 111, and the free section 22 is the part for positioning. The upper end of the free section 22 is bent with a floating connection section 23, the floating connection section 23 is arranged in the converging direction, a hook section 24 is bent on the floating connection section 23 and arranged towards the free section 22, and the hook section 24 and the floating connection section 23 form a floating connection slideway 25; a floating connection ring 3 is jointly installed on the floating connection slideway 25.

[0021] The restriction formed by jointly pulling the floating connection ring 3 through the floating connection slideway 25 enables the positioning steel bars 2 to jointly form a closed cage structure. During the wire feeding process, the steel wire 9 is not easily hooked by this embodiment, which is conducive to the smooth wire feeding. The cooperation between the floating connection slideway 25 and the floating connection ring 3 enables the upper end of the free section 22 to easily swing elastically, that is, the free section 22 is in a floating state. Preferably, the floating connection ring 3 and the floating connection slideway 25 are in clearance fit to ensure that the free section 22 can swing more easily relative to the floating connection ring 3. In addition, the lower end of the positioning steel bar 2 in this embodiment adopts the bent fixed section 21 to form a fixed connection with the reinforcing rib 12. At the lower end of the free section 22 that plays a role in positioning the steel wire coil 91, because it is close to the fixed section 21, the strength for positioning is sufficient; and the setting of the fixed section 21 will significantly reduce the bending resistance of the free section 22, prompting the free section 22 to swing more easily.

[0022] Through the above structure, when the steel wire 9 collides with the free section 22 during the wire feeding process, the free section 22 can rely on its own floating to produce an adaptive retreat for the collision. The collision between the steel wire 9 and the positioning steel bar 2 is significantly reduced, and the force of the collision of the steel wire 9 is not easily transmitted to the base 1 position. This embodiment is less affected by the swinging of the steel wire 9 and has good use stability.

[0023] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
