Description

The application claims the priority to Chinese Patent Application No. 201710066256.6 titled "STEEL STRIP PACKAGING MACHINE FOR SHEARING STEEL STRIP AND STEEL STRIP PACKAGING METHOD", filed with the China National Intellectual Property Administration on February 6, 2017, which is incorporated herein by reference in its entirety.

FIELD

The present application relates to the technical field of steel strip packaging, and in particular to a steel strip packaging machine for shearing a steel strip and a steel strip packaging method.

BACKGROUND

A steel strip packaging machine is a commonly used packaging machine, which is mainly used for packaging products such as various specifications of pipes, section bars, ingots and plates in non-ferrous metal and steel enterprises.
Referring to Figure 1, Figure 1 is a schematic view showing the structure of a steel strip packaging machine according to a specific embodiment in the conventional technology.
As shown in Figure 1, the conventional steel strip packaging machine generally includes an oil cylinder 01, an upper knife seat 02 and a lower knife seat 03. The upper knife seat 02 is connected to the oil cylinder 01, and can be driven to move up and down by the oil cylinder 01. An upper cutting die 021 and a stamping edge 022 are arranged at a lower portion of the upper knife seat 02, and a lower cutting die 031 is arranged at an upper portion of the lower knife seat 03.
In use, first, a steel strip 04 is wrapped around the goods to be bundled, and the two extending ends of the steel strip 04 are extended between the upper knife seat 02 and the lower knife seat 03, and then the oil cylinder 01 is operated to drive the upper knife seat 02 to move downward, and the steel strip can be buckled under the action of the upper cutting die 021 and the lower cutting die 031, at the same time, the stamping edge 022 can break the redundant steel strip 04 by stamping, so as to complete the packaging of the goods.
However, the stamping and breaking process of the steel strip 04 is completed simply relying on the stamping force of the stamping edge 022, and a large stamping force is required in the whole process. In order to withstand the large stamping force, the lower knife seat 03 is required to have a sufficient thickness, which is not beneficial to the tightening of the steel strip 04. Besides, since the operation is frequent, the large stamping force will also aggravate the wear of the stamping edge 022, which is not beneficial to prolongation of the service life of the stamping edge 022.
Therefore, a technical problem to be addressed by those skilled in the art is to provide a steel strip packaging machine with a small stamping force.

SUMMARY

An object of the present application is to provide a steel strip packaging machine with a small stamping force for shearing a steel strip and a steel strip packaging method.
To solve the above technical problem, a steel strip packaging machine for shearing a steel strip is provided according to the present application, including a first knife seat and a second knife seat. The first knife seat is movable in an axial direction, the first knife seat is provided with a first cutting die and a shear edge, and the second knife seat is provided with a second cutting die which is able to cooperate with the first cutting die. The steel strip packaging machine further includes a steel strip guiding member, the steel strip guiding member is arranged to abut against the shear edge, the steel strip is allowed to pass through the steel strip guiding member to wrap goods to be bundled, and a gap is provided between the steel strip guiding member and the second knife seat for allowing the steel strip wrapping the goods to be bundled to wrap back.
Compared with the conventional technology, a steel strip guiding member is added to the steel strip packaging machine according to the present application. During operation, the steel strip may pass through the steel strip guiding member first, then wrap around a periphery of the goods to be bundled, and finally wrap back to the gap between the steel strip guiding member and the second knife seat. In this way, there will be two layers of steel strip between the first cutting die and the second cutting die, including a first layer of steel strip located on the steel strip guiding member and a second layer of steel strip located between the steel strip guiding member and the second knife seat.
When the first knife seat is driven to move toward the second knife seat to shear off the first layer of steel strip, the first layer of steel strip cannot directly move toward the second layer of steel strip due to the support of the steel strip guiding member, a stamping force toward the second knife seat is applied to the first layer of steel strip by the shear edge, and a supporting force away from the second knife seat is applied to the first layer of steel strip by the steel strip guiding member. Because the steel strip guiding member is arranged to abut against the shear edge, the stamping force and the supporting force can act on a same position of the first layer of steel strip at the same time, to shear the first layer of steel strip, so that the stamping force required for shearing off the first layer of steel strip is greatly reduced, which can greatly prolong the service life of the shear edge.
Optionally, the steel strip guiding member is movable in the axial direction and is configured to press the steel strip that is wrapped back to the gap against the second knife seat.

DETAILED DESCRIPTION

For those skilled in the art to better understand technical solutions of the present application, the present application will be further described in detail in conjunction with drawings and embodiments hereinafter.
The words "first" and "second" in the application are used only to facilitate description of two or more components or structures that are identical or similar in structure and do not represent particular limitation to sequence.
Reference is made to Figure 2, and Figure 2 is a schematic view showing the structure of a steel strip packaging machine for shearing a steel strip according to a specific embodiment of the present application.
As shown in Figure 2, a steel strip packaging machine for shearing a steel strip is provided according to the present application, including a first knife seat 1, a second knife seat 2 and a steel strip guiding member. The first knife seat 1 is movable in an axial direction and is provided with a first cutting die 11 and a shear edge 12, and the second knife seat 2 is provided with a second cutting die 21 that is able to cooperate with the first cutting die 11. The steel strip guiding member is arranged to abut against the shear edge 12, a steel strip 3 is allowed to pass through the steel strip guiding member to wrap around goods to be bundled, and a gap is provided between the steel strip guiding member and the second knife seat 2 to allow the steel strip 3 configured for wrapping around the goods to be bundled to wrap back and pass through. The above "axial" movement refers to movement of the first knife seat 1 toward or away from the second knife seat 2, and it refers to "up and down" movement of the first knife seat 1 in Figure 2.
Compared with the conventional technology, the steel strip guiding member is added to the steel strip packaging machine according to the present application. During operation, the steel strip 3 may pass through the steel strip guiding member first, then wrap around a periphery of the goods to be bundled, and finally wrap back to the gap between the steel strip guiding member and the second knife seat 2. In this way, there will be two layers of steel strip 3 between the first cutting die 11 and the second cutting die 21, including a first layer of steel strip 31 located on the steel strip guiding member and a second layer of steel strip 32 between the steel strip guiding member and the second knife seat 2.
Reference is made to Figures 3 to 5, Figure 3 is a structural view showing a state of the steel strip packaging machine for shearing the steel strip according to the embodiment of the present application before the steel strip is sheared, Figure 4 is a structural view showing a state of the steel strip packaging machine for shearing the steel strip according to the embodiment of the present application when the steel strip is being sheared, and Figure 5 is a structural view showing a state of the steel strip packaging machine for shearing the steel strip according to the embodiment of the present application after the steel strip is sheared.
As shown in Figures 3 to 5, when the first knife seat 1 is driven to move toward the second knife seat 2 to shear off the first layer of steel strip 31, the first layer of steel strip 31 cannot directly move toward the second layer of steel strip 32 due to the support of the steel strip guiding member, a stamping force toward the second knife seat 2 is applied to the first layer of steel strip 31 by the shear edge 12, and a supporting force away from the second knife seat 2 is applied to the first layer of steel strip 31 by the steel strip guiding member. Because the steel strip guiding member is arranged to abut against the shear edge 12, the stamping force and the supporting force can act on a same position of the first layer of steel strip 31 at the same time, to shear the first layer of steel strip 31, so that the stamping force required for shearing off the first layer of steel strip 31 is greatly reduced, which can greatly prolong the service life of the shear edge 12.
On another aspect, since the stamping force required for shearing off the first layer of steel strip 31 is greatly reduced, a force for driving the first knife seat 1 to move toward the second knife seat 2 can be greatly reduced, that is, the stamping force applied to the second knife seat 2 will be greatly reduced. Thus, the second blade seat 2 having a small thickness can satisfy the requirement of use, which saves the manufacturing cost of the second knife seat 2, and thereby saving the manufacturing cost of the steel strip packaging machine.
It should be understood that, when the steel strip packaging machine is in operation, the goods to be bundled are generally placed below the second knife seat 2, the steel strip 3 passes through the gap between the first knife seat 1 and the second knife seat 2, and wrap around the periphery of the goods to be bundled, and then wrap back between the first knife seat 1 and the second knife seat 2, which means that the goods to be bundled is hung below the second knife seat 2. Thus, the greater the thickness of the second knife seat 2, the more difficult it is to tighten the steel strip 3. According to the steel strip packaging machine for shearing the steel strip of the present application, the second knife seat 2 has a small thickness, which facilitates tightening the goods to be bundled.
In addition, in the conventional technology, a cross section of the steel strip formed by stamping and breaking the first layer of steel strip 31 simply by the stamping force has lots of burrs, and when the bundled goods are transported, the burrs may cause damage to the transported goods themselves and transport staff. However, the steel strip packaging machine according to the present application can shear off the first layer of steel strip 31, and the cross section of the steel strip formed in this manner is more flat, which is more beneficial for ensuring the safety of staff and goods during transportation.
Further, the steel strip guiding member may move in the axial direction, and is able to press the steel strip 3 that is wrapped back between the steel strip guiding member and the second knife seat 2 against the second knife seat 2. The above "axial" movement refers to movement of the steel strip guiding member toward or away from the second knife seat 2, and it refers to "up and down" movement of the steel strip guiding member in Figure 2.
With the above arrangement, before the first layer of steel strip 31 is sheared, first, the steel strip guiding member is driven to move toward the second knife seat 2 to press the second layer of steel strip 32 against the second knife seat 2, then the first layer of steel strip 31 is pulled, and since the second layer of steel strip 32 has been pressed at this time, the steel strip 3 wrapping around the goods to be bundled is gradually tightened during the process of pulling the first layer of steel strip 31, so as to more effectively tighten the goods to be bundled.
Specifically, the steel strip guiding member may include a steel strip guiding plate 4, and the steel strip guiding plate 4 may be provided with a steel strip guiding hole 41. As shown in Figures 3 to 5, during use, the steel strip 3 may first pass through the steel strip guiding hole 41, and then wrap around the periphery of the goods to be bundled; and when the first knife seat 1 is driven to move toward the second knife seat 2 to shear the steel strip 31, a bottom of the steel strip guiding hole 41 can support the first layer of steel strip 31 and further cooperate with the shear edge 12 to shear off the first layer of steel strip 31. When the steel strip guiding plate 4 moves downward in the axial direction, one end of the steel strip guiding plate 4 close to the second knife seat 2 can press the second layer of steel strip 32 against the second knife seat 2, to facilitate pulling the first layer of steel strip 31, thereby tightening the goods to be bundled.
In fact, the steel strip guiding hole 41 can further play a certain guiding effect on the process that the steel strip 3 passes through the first knife seat 1 and the second knife seat 2 to wrap around the goods to be bundled. As shown in Figure 2, an opening of the steel strip guiding hole 41 is corresponding to the gap between the first knife seat 1 and the second knife seat 2, and the steel strip 3 passing through the steel strip guiding hole 41 can accurately pass through the gap between the first knife seat 1 and the second knife seat 2, thereby wrapping around the goods to be bundled.
The steel strip guiding member may be provided in other forms. For example, the steel strip guiding member may include only one layer of backing plate, and the backing plate is arranged above the second knife seat 2, and a gap is provided between the backing plate and the second knife seat 2. During use, the steel strip 3 may pass from above the backing plate, and then pass through the gap between the first knife seat 1 and the second knife seat 2, and finally wrap back between the backing plate and the second knife seat 2. Thus, when the first knife seat 1 is driven to move toward the second knife seat 2, the shear edge 12 can cooperate with the backing plate to shear the first layer of steel strip 31. Besides, the backing plate can move up and down in the axial direction, to press the second layer of steel strip 32 against the second knife seat 2, so as to more effectively tighten the goods to be bundled.
Based on the arrangement of the backing plate, the steel strip guiding member may further include a pressing plate located above the backing plate, and a gap is provided between the pressing plate and the backing plate for the steel strip 3 to pass through. When the backing plate presses the second layer of steel strip 32, and the first layer of steel strip 31 is pulled to tighten the goods to be bundled, the pressing plate can move downward in the axial direction, to press the first layer of steel strip 31 against the backing plate. In this way, when the first knife seat 1 is driven to move toward the second knife seat 2 to shear the first layer of steel strip 31, there is no need to provide a continuous tensioning force to the first layer of steel strip 31 to ensure the tightening of the goods to be bundled, which is more beneficial for shearing the first layer of steel strip 31.
It should be noted that, the above description of the two specific structural designs of the steel strip guiding member is only a preferred technical solution of the embodiment of the present application, and is not intended to limit the implementation scope of the steel strip packaging machine for shearing the steel strip according to the present application. On the premise that the function of the steel strip packaging machine is satisfied, the steel strip guiding member may be arranged in other forms. In specific implementation, the specific structure of the steel strip guiding member may be arranged by those skilled in the art according to actual conditions.
With continuous reference to Figure 2, the steel strip packaging machine may further include a first oil cylinder 5 and a second oil cylinder 6. The first oil cylinder 5 is connected to the steel strip guiding member, to drive the steel strip guiding member to move in the axial direction, and the second oil cylinder 6 is connected to the first knife seat 1, to drive the first knife seat 1 to move in the axial direction. The first knife seat 1 and the steel strip guiding member may be driven by a motor or manually. In specific use, a specific driving mode may be chosen by those skilled in the art according to actual conditions such as equipment sizes, working environment and the like.
One end of the steel strip guiding plate 4 away from the second knife seat 2 may have a connecting portion 42 which is bent and extended outwardly, and thus the first oil cylinder 5 can be connected to the connecting portion 42. In this way, the two oil cylinders can be separated apart by a certain distance during mounting, which can avoid mutual interference of mounting positions of the two oil cylinders during the mounting process without affecting operation of the two oil cylinders. The above being bent and extended "outwardly" refers to that the connecting portion 42 is bent and extended in a direction away from the mounting position of the second oil cylinder 6.
The steel strip packaging machine may further include a mounting plate 7, the mounting plate 7 is located above the first knife seat 1 and the steel strip guiding member, and both the first oil cylinder 5 and the second oil cylinder 6 may be further arranged on the mounting plate 7, to facilitate mounting and fixing of the two oil cylinders.
Based on the above technical solutions, the specific structure of the second knife seat 2 may be further modified. A slide stop sheet 8 may be provided at a position of the second knife seat 2 corresponding to the steel strip guiding member. When the steel strip guiding member is driven to press the second layer of steel strip 32 against the second knife seat 2, the second layer of steel strip 32 can abut against a surface of the slide stop sheet 8. Since the surface of the slide stop sheet 8 is rough, a frictional force between the slide stop sheet 8 and the second layer of steel strip 32 can be increased, so that when the first layer of steel strip 31 is pulled, the second layer of steel strip 32 can be placed between the steel strip guiding member and the second knife seat 2 more stably without moving, which is more beneficial for tightening the goods to be bundled. The slide stop sheet 8 may be a metal sheet having a rough surface, and the metal sheet may be welded to the second knife seat 2.
Based on the different types of the steel strip packaging machine for shearing the steel strip, different steel strip packaging methods are further provided according to the present application.
For the technical solution that the steel strip guiding member cannot move in the axial direction, when the steel strip is used for packaging, the following steps are provided:

For the technical solution that the steel strip guiding member can move in the axial direction, when the steel strip is used for packaging, the following steps are added between the above steps S1 and S2:

step S11, driving the steel strip guiding member to move toward the second knife seat 2, to press the steel strip 3, which is wrapped back to the gap between the steel strip guiding member and the second knife seat 2, against the second knife seat 2; and

step S2, driving the backing plate to move toward the second knife seat 2, to press the steel strip 3 that is wrapped back to the gap between the backing plate and the second knife seat 2 against the second knife seat 2;
step S3, tightening the steel strip 3 above the backing plate, so as to tighten the goods to be bundled; and
step S4, driving the pressing plate to move toward the backing plate, to press the steel strip 3 between the pressing plate and the backing plate against the backing plate, driving the first knife seat 1 to move toward the second knife seat 2, the first cutting die 11 can cooperate with the second cutting die 21, so as to buckle two layers of the steel strip 3 between the first cutting die 11 and the second cutting die 21, and the shear edge 12 can cooperate with the backing plate, so as to shear off the steel strip 3 between the pressing plate and the backing plate.
