Technical Field

[0001] This utility model relates to the field of punching equipment technology, and in particular to a punching machine for labels. Background Technology

[0002] A label punch is a device specifically designed for punching holes in labels.

[0003] Currently, most label punching machines on the market use a manual, continuous feeding method. After a label is punched, the operator needs to remove it and then place a new label for punching. While this traditional feeding method can achieve the punching operation, it has obvious drawbacks. Due to the limited speed of manual feeding, the frequent removal and placement of labels consumes a lot of time, resulting in a slow overall punching speed and low production efficiency, making it difficult to meet the needs of large-scale, high-efficiency label processing. At the same time, the stability and consistency of manual operation are poor, and human factors can easily lead to inaccurate label placement, which in turn affects the accuracy and quality of punching.

[0004] Therefore, we provide a punching machine for labels. Utility Model Content

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] Example 1: A punching machine for labels, such as Figures 1-4 As shown, it includes a punching table 1, which is equipped with a feeding structure, an intermittent pushing structure and a punching structure.

[0029] The feeding structure includes a base plate 2, which is welded to a cross-shaped groove plate 21. The cross-shaped groove plate 21 has accommodating cavities in both the horizontal and vertical directions. The vertical accommodating groove can accommodate multiple sets of punched parts 3 at one time. There is a first push rod 22 in the vertical accommodating groove. The end of the first push rod 22 extends out of the groove, and the two sides of the end of the first push rod 22 are connected to a return spring 23. The other end of the return spring 23 is installed at the junction of the vertical and horizontal accommodating grooves.

[0030] The intermittent feeding structure is installed at the right port of the transverse receiving groove of the cross groove plate 21;

[0031] The perforated structure is installed at the outlet on the left side of the transverse receiving groove of the cross-shaped groove plate 21.

[0032] In use, multiple sets of punching parts 3 are placed sequentially into the longitudinal receiving groove of the cross-shaped groove plate 21. Under the action of the return spring 23, the first push rod 22 is initially positioned near the bottom of the longitudinal receiving groove, and the return spring 23 is in a stretched state, preparing for the subsequent pushing of the punching parts 3. As the punching operation proceeds, when the punching parts 3 in the transverse receiving groove are pushed out by the intermittent pushing structure, the first push rod 22 in the longitudinal receiving groove, under the elastic force of the return spring 23, pushes a set of punching parts 3 upward, causing them to enter the transverse receiving groove, completing the automatic feeding process and continuously providing material for the punching operation. The reciprocating motor 42 starts, and its output end is connected via a continuous... The rod drives the adjusting column 41 to reciprocate. The adjusting column 41 moves in the handle groove at one end of the second push rod 4, which in turn drives the second push rod 4 to perform intermittent pushing action in the transverse receiving groove of the cross groove plate 21. The punched parts 3 in the transverse receiving groove are slowly pushed one by one to the left exit position. One punched part 3 is pushed at a time to ensure a stable punching rhythm. When the punched part 3 is pushed to the left exit position of the transverse receiving groove of the cross groove plate 21, the cylinder 51 on the L-shaped frame 5 is started. The output end of the cylinder 51 pushes the assembly box 52 downward. The punching motor 53 in the assembly box 52 is started, which drives the punched part 3 to perform punching operation on the punched part 3 in the exit position.

[0033] like Figures 1-4 As shown, the return spring 23 has hooks 231 at both ends. The return spring 23 is suspended on the connecting guide post 24 through the hooks 231 at both ends. The connecting guide post 24 is installed at both ends of the junction of the first push rod 22 and the longitudinal and transverse receiving grooves. The connecting guide post 24 has threads at both ends. The connecting guide post 24 is spirally installed at both ends of the junction of the first push rod 22 and the longitudinal and transverse receiving grooves. In addition, the connecting guide post 24 has a retaining ring in the middle and a matching nut 25 at one end.

[0034] By setting hooks 231 at both ends of the return spring 23, the return spring 23 and the connecting guide post 24 can be easily connected. The suspension method of hooks 231 makes the installation and removal of the return spring 23 relatively easy. The connecting guide post 24 is installed at both ends of the junction of the first push rod 22 and the longitudinal and transverse receiving grooves, and is installed at this position by the threaded screws at both ends, which facilitates the overall disassembly of the connecting guide post 24 and the return spring 23. The retaining ring in the middle of the connecting guide post 24 and the nut 25 on one side can limit the axial movement range of the return spring 23 on the connecting guide post 24, preventing the return spring 23 from excessive displacement and affecting its normal operation.

[0035] like Figures 1-4 As shown, the intermittent feeding structure includes a second feeding rod 4 installed at one end of the transverse receiving groove of the cross-shaped groove plate 21. One end of the second feeding rod 4 is provided with a handle groove, and an adjusting column 41 is provided in the handle groove. The adjusting column 41 is connected to the output end of the reciprocating motor 42 through a connecting rod. The reciprocating motor 42 is electrically connected to the controller 43. The controller 43 can precisely control the operating frequency of the reciprocating motor 42. In the label punching operation, different types and specifications of labels may require different punching speeds and feeding rhythms. Through the controller 43, the operator can adjust the operating frequency of the reciprocating motor 42 according to the actual production needs, thereby changing the feeding frequency of the second feeding rod 4. The controller 43 is an existing mature product, and the connection technology is also an existing mature technology, which will not be described in detail here.

[0036] like Figures 1-4 As shown, the discharge port end of the cross-shaped groove plate 21 is provided with a material tray 6. The material tray 6 has several placement cavities pre-set in an array. After the label is punched in the punching structure, it will be discharged from the discharge port of the cross-shaped groove plate 21. The material tray 6 can receive these punched labels. The placement cavities set in an array on the material tray 6 can place the labels in an orderly manner, avoiding random stacking and messy placement of the labels, which helps to sort, count and package the labels in the future.

[0037] like Figures 1-4 As shown, the punching structure includes an L-shaped frame 5, on which a cylinder 51 is mounted. The output end of the cylinder 51 is connected to the assembly box 52. The assembly box 52 contains a punching motor 53, and the output end of the punching motor 53 is provided with a punching component 3.

[0038] Example 2: A punching machine for labels, such as Figures 1-4 As shown, an L-shaped extension baffle 54 is provided on one side of the assembly box 52. When the drilling part 3 located below the assembly box 52 performs a drilling operation, the L-shaped extension baffle 54 is exactly at the outlet position of the transverse receiving groove of the cross groove plate 21.

[0039] In use, when the punching part 3 is pushed to the left outlet position of the transverse receiving groove of the cross groove plate 21, the cylinder 51 on the L-shaped frame 5 is activated. The output end of the cylinder 51 pushes the assembly box 52 downward. At this time, due to the L-shaped extension baffle 54 set on one side of the assembly box 52, when the punching part 3 performs the drilling operation, the L-shaped extension baffle 54 is exactly at the outlet position of the transverse receiving groove of the cross groove plate 21. At this time, the second push rod 4 on the right side also plays a role. When the second push rod 4 pushes the punching part 3 to the outlet position to accept the punching, the L-shaped extension baffle 54 tightly abuts against the punching part 3 from one side, forming a front and rear clamping force with the second push rod 4. This provides a reliable limit for the punching part 3, effectively preventing the punching part 3 from being displaced due to the punching impact force during the punching process, and ensuring that the punching position is accurate.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
