[0042] like Figure 1 As shown, the linear cylinder is connected to the strip push rod 8 to drive the strip push rod 8 to move back and forth; there are problems such as the inconvenience of replacing the strip push rod 8 and the inability to adjust the feed stroke.

[0043] In view of this, see Figures 2 to 5 The strip ejecting device provided by the embodiment of the present invention includes a rotary driving member 1, a guide rail fixing seat 2, a cylinder fixing seat 3, a push rod fixing seat 5, a rotating block 10 and a strip push rod 8; the rotary driving member 1 is connected to the cylinder fixing seat 3, and the driving end of the rotary driving member 1 is connected to the rotating block 10, and a transmission member 13 is installed on the surface of the rotating block 10; the guide rail fixing seat 2 is provided with a long through hole, the transmission member 13 of the rotating block 10 is inserted into the long through hole, and the guide rail fixing seat 2 is slidably matched with the cylinder fixing seat 3 to make the guide rail fixing seat 2 move along the first direction a; the push rod fixing seat 5 is installed on the guide rail fixing seat 2, and the strip push rod 8 is installed on the upper surface of the push rod fixing seat 5.

[0044] Specifically, the rotary drive member 1 is configured as a rotary cylinder, which drives the rotary block 10 to swing. Furthermore, the long through hole penetrates the guide rail fixing base 2 along the height direction of the guide rail fixing base 2, and the length direction of the long through hole is arranged along the second direction b, which is perpendicular to the first direction a.

[0045] The rotary drive member 1 is fixed to the cylinder fixing seat 3, which provides support and fixing for the rotary drive member 1. The rotating block 10 is connected to the driving end of the rotary drive member 1 and is connected to the guide rail fixing seat 2 through the transmission member 13, so that the rotary drive member 1 drives the rotating block 10 to swing around the driving end of the rotary drive member 1, and the transmission member 13 drives the guide rail fixing seat 2 to move; because the guide rail fixing seat 2 and the cylinder fixing seat 3 are in sliding cooperation, the transmission member 13 drives the guide rail fixing seat 2 to move back and forth along the first direction a. The push rod fixing seat 5 is installed on the guide rail fixing seat 2, and when the guide rail fixing seat 2 moves back and forth along the first direction a, the push rod fixing seat 5 also moves back and forth along the first direction a; the strip push rod 8 is installed on the push rod fixing seat 5, and the push rod fixing seat 5 provides support and fixing for the strip push rod 8; and because the strip push rod 8 is installed on the upper surface of the push rod fixing seat 5, it is convenient to replace the strip push rod 8. When using the strip ejection device, the rotary drive member 1 drives the rotary block 10 to swing, and the rotary block 10 drives the guide rail fixing seat 2 to move along the first direction a; the guide rail fixing seat 2 drives the push rod fixing seat 5 to move along the first direction a; and the push rod fixing seat 5 drives the strip push rod 8 to move along the first direction a. The strip ejection device has a compact and simple structure, which can effectively reduce the failure rate; the strip push rod 8 is installed at the top of the entire device, making it easy to replace the strip push rod 8. The feed distance of the strip push rod 8 is controlled by adjusting the swing angle of the rotary drive member 1, and the ejection speed of the strip push rod 8 is slowed down, reducing the possibility of strip warping caused by excessive ejection speed of the strip push rod 8.

[0046] The structure and shape of the strip ejection device are described in detail below:

[0047] In an optional solution of the embodiment of the present utility model, the lower surface of the cylinder fixing seat 3 is connected to the rotary drive member 1, and a linear guide rail 4 is installed on the upper surface, and the linear guide rail 4 extends along the first direction a; the guide rail fixing seat 2 is slidably matched with the linear guide rail 4.

[0048] Specifically, the rotating block 10 and the cylinder fixing seat 3 are spaced apart and are both located above the rotating driving member 1 .

[0049] The rotary drive member 1 is mounted below the cylinder mount 3, making the strip ejection device compact and space-saving. The guide rail mount 2 slides with the linear guide 4, achieving sliding cooperation between the guide rail mount 2 and the cylinder mount 3, thereby enabling the guide rail mount 2 to reciprocate along the first direction a.

[0050] In the optional solution of the embodiment of the present utility model, see Figure 2 The lower surface of the guide rail fixing seat 2 is provided with a sliding protrusion 16, and the lower surface of the sliding protrusion 16 is provided with a sliding groove, which slides with the linear guide rail 4; the cross-section of the sliding groove matches the cross-section of the linear guide rail 4, and both are set to polygonal.

[0051] Specifically, the position of the sliding protrusion 16 corresponds to the position of the cylinder fixing seat 3; in this embodiment, the side wall of the sliding groove is provided with a plurality of bends to prevent the linear guide rail 4 from falling out of the sliding groove.

[0052] The lower surface of the guide rail fixing seat 2 is provided with a sliding protrusion 16, which realizes the sliding cooperation between the guide rail fixing seat 2 and the cylinder fixing seat 3 without affecting the swing of the rotating block 10, avoiding the problem that there is no gap between the guide rail fixing seat 2 and the cylinder fixing seat 3 and the rotating block 10 cannot be installed.

[0053] In an optional solution of the embodiment of the present utility model, the push rod fixing seat 5 is slidably matched with the guide rail fixing seat 2 so that the push rod fixing seat 5 moves along the first direction a.

[0054] Specifically, the lower surface of the push rod fixing seat 5 is slidably matched with the upper surface of the guide rail fixing seat 2, so that the structure of the strip ejecting device is compact.

[0055] The push rod fixing seat 5 is slidably matched with the guide rail fixing seat 2. When the guide rail fixing seat 2 moves forward too far along the first direction a, the push rod fixing seat 5 also moves forward too far, causing the strip to touch other parts; at this time, the push rod fixing seat 5 can move backward along the first direction a to avoid damage to the strip and other parts.

[0056] In the optional solution of the embodiment of the present utility model, see Figure 4The push rod fixing seat 5 and the guide rail fixing seat 2 are slidably matched through the ball guide rail 11, and the ball guide rail 11 extends along the first direction a.

[0057] Specifically, the ball guide rail 11 is a rolling guide, in which steel balls roll endlessly between the slider and the rail, so that the push rod fixing seat 5 can easily perform linear motion with high precision along the rail.

[0058] The push rod fixing seat 5 and the guide rail fixing seat 2 are slidably matched with each other through the ball guide rail 11 , thereby improving the sliding accuracy of the push rod fixing seat 5 .

[0059] In an optional solution of the embodiment of the present invention, the strip ejection device further includes an overload identification component, which is installed on the guide rail fixing seat 2 to identify the position of the push rod fixing seat 5.

[0060] Specifically, the push rod fixing seat 5 is slidably matched with the guide rail fixing seat 2. When the guide rail fixing seat 2 moves forward too far along the first direction a, the push rod fixing seat 5 also moves forward too far, causing the strip to touch other parts; at this time, the push rod fixing seat 5 can move backward along the first direction a, and the position of the push rod fixing seat 5 relative to the guide rail fixing seat 2 changes. The overload identification component can recognize this information and alarm.

[0061] The overload identification component is used to identify the position of the push rod fixing seat 5 and to alarm when the position of the push rod fixing seat 5 moves relative to the guide rail fixing seat 2.

[0062] In the optional solution of the embodiment of the present utility model, see Figure 2 The overload identification component includes a light shielding plate 6 and a light sensor 7. One end of the light shielding plate 6 is installed on the guide rail fixing seat 2, and the other end is provided with a light shielding protrusion, which is located above the push rod fixing seat 5; the light sensor 7 is connected to the light shielding plate 6.

[0063] Specifically, in this embodiment, under normal circumstances, the light-shielding protrusion is opposite the push rod holder 5. When the guide rail holder 2 moves forward too far in the first direction a, the push rod holder 5 also moves forward too far, causing the strip to contact other parts. At this time, the push rod holder 5 can move backward in the first direction a, changing its position relative to the guide rail holder 2 so that the light-shielding protrusion no longer faces the push rod holder 5. The light sensor can then recognize this abnormality and issue an alarm. Of course, under normal circumstances, the light-shielding protrusion does not face the push rod holder 5, and under abnormal circumstances, the light-shielding protrusion faces the push rod holder 5, which should also be within the scope of protection of the present embodiment of the utility model.

[0064] The connection between the light shielding plate 6 and the light sensor realizes overload recognition of the strip ejecting device and improves the safety performance of the strip ejecting device.

[0065] In an optional solution of the embodiment of the present utility model, the strip ejection device further includes a reset component, which is respectively connected to the guide rail fixing seat 2 and the push rod fixing seat 5 to reset the push rod fixing seat 5.

[0066] Specifically, the push rod fixing seat 5 is slidably matched with the guide rail fixing seat 2. When the guide rail fixing seat 2 moves forward too far in the first direction a, the push rod fixing seat 5 also moves forward too far, causing the strip to touch other parts; at this time, the push rod fixing seat 5 can move backward along the first direction a; after the obstacle in front is removed or the guide rail fixing seat 2 moves backward, the reset assembly drives the push rod fixing seat 5 to reset.

[0067] The reset assembly realizes the automatic reset of the push rod fixing seat 5, thereby improving the automation of the strip ejection device.

[0068] In the optional solution of the embodiment of the present utility model, see Figure 2 and Figure 3 The reset assembly includes a mounting block 12, a buffer bending plate 15, a reset rod 14 and an elastic member; the mounting block 12 is fixed to the guide rail fixing seat 2, one end of the reset rod 14 is connected to the mounting block 12, and the other end is provided with a limiting protrusion; the buffer bending plate 15 includes a first section and a second section, the first section and the second section are vertically connected, the first section is connected to the push rod fixing seat 5, and the second section is sleeved with the reset rod 14; one end of the elastic member abuts the second section, and the other end abuts the limiting protrusion.

[0069] Specifically, the elastic member is configured as a spring (not shown in the figure); the buffer bending plate 15 is made of sheet metal and is bent to form a buffer bending plate 15 having a first section and a second section. In this embodiment, the reset rod 14 is threadedly connected to the mounting block 12, and the connection method is simple and convenient for installing the spring and the buffer bending plate 15. The push rod fixing seat 5 is slidably matched with the guide rail fixing seat 2. When the guide rail fixing seat 2 moves forward too far along the first direction a, the push rod fixing seat 5 moves forward too far, causing the strip to touch other parts; at this time, the push rod fixing seat 5 can move backward along the first direction a, driving the buffer bending plate 15 to move backward, and the buffer bending plate 15 compresses the spring; after the obstacle in front is removed or the guide rail fixing seat 2 is moved back, the spring returns to its original shape, driving the buffer bending plate 15 to move forward, and the buffer bending plate 15 drives the push rod fixing seat 5 to move forward and reset.

[0070] The push rod fixing seat 5 can be automatically reset by the elastic member and the buffer bending plate 15, and the structure is simple and easy to install.

[0071] In an optional solution of the embodiment of the present invention, the strip push rod 8 is detachably connected to the push rod fixing seat 5 through a fastener.

[0072] Specifically, the fastener is configured as a screw, which passes through the strip push rod 8 and is threadedly connected to the push rod fixing seat 5, making it convenient to install and disassemble the strip push rod 8.

[0073] The strip push rod 8 is detachably connected to the push rod fixing seat 5 by screws, which makes it easy to replace and repair the strip push rod 8.

[0074] It should be noted that, unless there is any conflict, the features in the embodiments of this application can be combined with each other.

[0075] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
