Description

Technical Field

[0001] The utility model relates to the technical field of balers, in particular to a counterweight wheel device for a baler. Background Art

[0002] The steel rolling wire rod baler is used for packing and encapsulating finished coils. The baler is responsible for compacting and packing the threaded coils, and the packing wire used is round bar steel. The baler compacts and packages the coils evenly distributed along the circumference through 4 wire feeding mechanisms. Since the wire feeding path of the packing wire is long, and the wire feeding mechanism needs to complete forward packing and backward transportation of the coils during the packing process, the packing wire is prone to knotting and bending, which is not conducive to the next packing; before packing and wire feeding, the gravity of the counterweight wheel is required to tighten and straighten the packing wire for the wire feeder to use. To ensure that the packing wire is always straight during wire feeding, it is necessary to increase the counterweight wheel to ensure that the packing wire is always in a straight state.

[0003] At present, the commonly used counterweight wheel device for a baler includes at least one set of counterweight wheel components. Each set of counterweight wheel components includes a first slideway and a second slideway. The first slideway and the second slideway are arranged vertically side by side on the ground. A first counterweight wheel is arranged on the left side of the first slideway, and the first counterweight wheel can move up and down along the first slideway. A second counterweight wheel is arranged on the right side of the second slideway, and the second counterweight wheel can move up and down along the second slideway. The packing wire is tightened by the up and down movement of the first counterweight wheel and the second counterweight wheel. The position of the first counterweight wheel and the second counterweight wheel falling is controlled by a pneumatic brake. When the pneumatic brake has problems, the pneumatic brake cannot accurately and timely stop the first counterweight wheel and the second counterweight wheel. The first counterweight wheel and the second counterweight wheel directly impact the ground due to their own weight, causing damage to the ground and the counterweight wheel.

Detailed implementation mode

[0016] The present utility model will be further described below in conjunction with the accompanying drawings and the detailed implementation mode.

[0017] As Figure 1 shown, the counterweight wheel device of the packing machine of the present utility model includes a first slideway 1 and a second slideway 2. The first slideway 1 and the second slideway 2 are arranged side by side. A first counterweight wheel 3 is arranged on the left side of the first slideway 1, and the first counterweight wheel 3 can move back and forth along the first slideway 1. A second counterweight wheel 4 is arranged on the right side of the second slideway 2, and the second counterweight wheel 4 can move back and forth along the second slideway 2. It also includes a pressure-bearing steel plate 5, a first buffer half tire 6 and a second buffer half tire 7. A relief hole is arranged in the middle of the pressure-bearing steel plate 5, and the pressure-bearing steel plate 5 is sleeved outside the first slideway 1 and the second slideway 2 through the relief hole;

[0018] The first buffer half tire 6 is detachably arranged on the left half of the pressure-bearing steel plate 5, and the first buffer half tire 6 is located directly below the first counterweight wheel 3. The second buffer half tire 7 is detachably arranged on the right half of the pressure-bearing steel plate 5, and the second buffer half tire 7 is located directly below the second counterweight wheel 4;

[0019] At least one first connection hole is arranged at each end of the first buffer half tire 6, and at least one second connection hole is arranged at each end of the second buffer half tire 7. A connecting fastener 8 passes through a first connection hole and a second connection hole to detachably connect the first buffer half tire 6 and the second buffer half tire 7 together.

[0020] Both the first buffer half tire 6 and the second buffer half tire 7 are made of rubber. The first buffer half tire 6 and the second buffer half tire 7 can be understood as a complete tire divided into two halves. The first buffer half tire 6 and the second buffer half tire 7 can absorb the impact force when the first counterweight wheel and the second counterweight wheel fall, effectively reducing the possibility of damage to the counterweight wheel and the ground.

However, both the first buffer half tire 6 and the second buffer half tire 7 are detachably arranged and used separately, which is convenient for replacement. When replacing, only the problematic side needs to be replaced, effectively reducing the use cost.

[0022] Specifically, the pressure-bearing steel plate 5 mainly serves to bear the first buffer half tire 6 and the second buffer half tire 7. The pressure-bearing steel plate 5 is located between the ground and the first counterweight wheel 3 and the second counterweight wheel 4, and also indirectly plays a role in protecting the ground. For the convenience of installing the pressure-bearing steel plate 5, the pressure-bearing steel plate 5 is fixed to the ground through anchor bolts, and the pressure-bearing steel plate 5 is formed by welding two steel plates together.

[0023] To further improve the installation and connection strength of the first buffer half tire 6 and the second buffer half tire 7 and ensure the use effect of the first buffer half tire 6 and the second buffer half tire 7, for another example Figure 1 as shown, a third connection hole is provided in the lower layer of the first buffer half tire 6. The first connecting bolt is welded to the pressure-bearing steel plate 5, and the first connecting bolt passes through the third connection hole to detachably arrange the first buffer half tire 6 on the pressure-bearing steel plate 5; a fourth connection hole is provided in the lower layer of the second buffer half tire 7. The second connecting bolt is welded to the pressure-bearing steel plate 5, and the second connecting bolt passes through the fourth connection hole to detachably arrange the second buffer half tire 7 on the pressure-bearing steel plate 5.

[0024] The connecting fastener 8 can use a conventional fastener. For example, it includes a connecting chain. One end of the connecting chain is provided with a hook, and the other end of the connecting chain is provided with a snap ring. The hook can form a snap structure with the snap ring.

[0025] To further improve the overall strength of the first buffer half tire 6 and the second buffer half tire 7 and increase the service time, for another example Figure 1 as shown, the present utility model is further provided with a fixing bracket 9 and a fixed connecting wire 10. The fixing bracket 9 is fixed to the ground. One end of the fixed connecting wire 10 is connected to the connecting fastener 8, and the other end is connected to the fixing bracket 9. The fixing bracket 9 can be a wire feeding frame steel structure, a ladder, etc.
