Description

Technical Field

[0001] This application belongs to the technical field of box body processing. More specifically, it relates to a punching mechanism and a box body processing device. Background Art

[0002] An existing paper box includes a frame body and a top cover covering one end of the frame body. A surrounding plate is connected to the top cover and is arranged around the outer periphery of the frame body. Ears are provided on the surrounding plate. During processing, through holes need to be opened on the ears and the frame body. The existing punching mechanism drives a pressing plate to press the ears tightly through a cylinder and simultaneously drives a punching needle to punch holes. After the punching is completed, the cylinder drives the pressing plate and the punching needle to reset. The frictional force when the punching needle separates from the through hole will cause the edge of the through hole to be pulled outwards, resulting in defects. Summary of the Utility Model

[0003] The purpose of the embodiments of this application is to provide a punching mechanism and a box body processing device to solve the technical problem in the existing technology that after the punching is completed, the cylinder drives the pressing plate and the punching needle to reset, which will cause the edge of the through hole to be pulled outwards, resulting in defects.

[0004] To achieve the above purpose, the technical solution adopted in this application is: to provide a punching mechanism, including:

[0005] A first base;

[0006] A first positioning seat, installed on the first base, and the first positioning seat is used to position and support the box body;

[0007] A punching assembly, including an abutting member, a support seat that slidably supports the abutting member, an elastic member for elastically pushing the abutting member to abut against the box body, a punching member provided on the support seat, and a first driver for driving the support seat to approach the box body. A positioning hole is opened on the abutting member, the punching member is installed on the support seat at a position corresponding to the positioning hole, the elastic member is in abutting connection with the abutting member and the support seat, and the power output end of the first driver is connected to the support seat; the perpendicular distance between the abutting member and the first positioning seat is less than the perpendicular distance between the punching member and the first positioning seat.

[0008] By adopting the first positioning seat, the box body can be positioned and supported, ensuring the stability of the position of the box body, so as to facilitate punching the box body; when the first driver drives the support seat to move towards the first positioning seat, the support seat drives the abutting member to move towards the direction close to the paper box. Since the vertical distance between the abutting member and the first positioning seat is less than the distance between the punching member and the first positioning seat, the abutting member abuts against the box body first and presses the box body tightly; and since the abutting member is slidably supported on the support seat, when the abutting member presses the box body tightly, the punching member can continue to move towards the box body, and the free end of the punching member extends out of the positioning hole to punch a hole at the position corresponding to the positioning hole on the box body; by adopting the elastic member, when the punching member and the abutting member simultaneously abut against the box body, the elastic member applies an elastic force to the abutting member, so that the abutting member presses the box body tightly. When the first driver drives the support seat to reset, the punching member moves away from the first positioning seat. When the punching member is withdrawn from the perforation, the abutting member still presses the box body under the action of the elastic member, realizing the delayed separation of the abutting member, thereby preventing the periphery of the perforation from being pulled up by the punching member to a certain extent, preventing the ear part from separating or tearing, improving the appearance quality, and enhancing the qualified rate of punching the box body.

[0060] Please refer to Figures 3 to 10, the punching mechanism provided by the embodiments of the present application will be described below. The punching mechanism 100 includes a first base 10, a first positioning seat 20, and a punching assembly 30; the first positioning seat 20 is installed on the first base 10, and the first positioning seat 20 is used to position and support the box body 90; the punching assembly 30 includes an abutting member 31, a support seat 32, an elastic member 33, a punching member 34, and a first driver 35. The support seat 32 slidably supports the abutting member 31. The elastic member 33 is used to elastically push the abutting member 31 to abut against the box body 90. The punching member 34 is arranged on the support seat 32. The first driver 35 is used to drive the support seat 32 to approach the box body 90. A positioning hole 310 is formed in the abutting member 31. The punching member 34 is installed at a position corresponding to the positioning hole 310 on the support seat 32. The elastic member 33 is in abutting connection with the abutting member 31 and the support seat 32. The power output end of the first driver 35 is connected to the support seat 32; the vertical distance between the abutting member 31 and the first positioning seat 20 (such as Figure 3 the distance along the Y-axis direction in) is less than the vertical distance between the punching member 34 and the first positioning seat 20. When it is necessary to punch the box body 90, the box body 90 is placed on the first positioning seat 20. By using the first positioning seat 20, the box body 90 can be positioned and supported, ensuring the stability of the position of the box body 90, so as to facilitate punching the box body 90; when the first driver 35 drives the support seat 32 to move towards the first positioning seat 20, the support seat 32 drives the abutting member 31 to move towards the direction close to the paper box 90. Since the vertical distance between the abutting member 31 and the first positioning seat 20 is less than the distance between the punching member 34 and the first positioning seat 20, the abutting member 31 abuts against the box body 90 first and presses the box body 90 tightly; and since the abutting member 31 is slidably supported on the support seat 32, when the abutting member 31 presses the box body 90 tightly, the punching member 34 can continue to move towards the box body 90, and the free end of the punching member 34 extends out of the positioning hole 310, punching a hole at the position corresponding to the positioning hole 310 on the box body 90; by using the elastic member 33, when the punching member 34 and the abutting member 31 simultaneously abut against the box body 90, the elastic member 33 exerts an elastic force on the abutting member 31, so that the abutting member 31 presses the box body 90 tightly. When the first driver 35 drives the support seat 32 to reset, the punching member 34 moves towards the direction away from the first positioning seat 20. When the punching member 34 is withdrawn from the through hole 901, the abutting member 31 still presses the box body 90 tightly under the action of the elastic member 33, so as to prevent the periphery of the through hole 901 from being pulled up by the punching member 34 to a certain extent, prevent the ear portion 93 from separating or tearing, improve the appearance quality, and increase the qualified rate of punching the box body 90. Among them, the free end of the punching member 34 refers to the end of the punching member 34 close to the first positioning seat 20.

[0061] In an embodiment of the present application, please refer to Figures 3 to 6, a sliding rod 36 is provided on the abutting member 31, and a sliding sleeve 37 is provided on the support seat 32. The sliding sleeve 37 is slidably sleeved on the sliding rod 36. By using the cooperation of the sliding sleeve 37 and the sliding rod 36, the abutting member 31 can be guided to slide linearly relative to the support seat 32 (such as the Y-axis direction in Figure 3 ), improving the stability of the abutting member 31. The length direction of the sliding rod 36 (such as the Y-axis direction in Figure 3 ) is the same as the direction in which the first driver 35 drives the support seat 32 to slide. Of course, in other embodiments of the present application, a guide rail slider structure may also be used, or a sliding hole may be formed in the support seat 32 to cooperate with the sliding rod to realize the sliding connection between the abutting member 31 and the support seat 32.

[0062] In an embodiment of the present application, please refer to Figures 3 to 6 , the number of the sliding rods 36 is two, and the two sliding rods 36 are respectively located at both ends of the abutting member 31; the positioning hole 310 is located in the middle of the abutting member 31; the number of the sliding sleeves 37 is two, and the two sliding sleeves 37 correspond to the two sliding rods 36 one by one. By using two sliding rods 36, it is beneficial to further improve the stability of the abutting member 31 when sliding relative to the support seat 32.

[0063] In an embodiment of the present application, please refer to Figures 3 to 6 , the elastic member 33 is a spring. By using a spring, when the punching member 34 contacts or separates from the surface of the box body 90, the abutting member 31 can be kept pressing against the box body 90, so as to prevent the surface of the box body 90 from being damaged during the reset process of the punching member 34.

[0064] Optionally, the spring is sleeved on the sliding rod 36. In this way, it is beneficial to control the position of the spring, ensure the direction of the elastic force, and facilitate the assembly of the spring.

[0065] Optionally, one end of the sliding rod 36 is connected to the abutting member 31, the other end of the sliding rod 36 passes through the sliding sleeve 37, and a limit cap is provided at the end of the sliding rod 36 passing through the sliding sleeve 37. In this way, the sliding rod 36 can be prevented from separating from the support seat 32. The sliding rod 36 can be a screw rod, which is beneficial to reducing costs.

[0066] In an embodiment of the present application, please refer to Figures 3 to 6, one end of the punching member 34 close to the first positioning seat 20 is provided with an inclined surface 341, and the range of the angle α between the inclined surface 341 and the length direction of the punching member 34 is 60° - 89°. The length direction of the punching member 34 is the same as the X-axis direction. In this way, on the one hand, it can avoid the end of the punching member 34 being too sharp, causing the tip to expand and extrude outward after inserting into the box body 90 to form a perforation 901, resulting in irregular rupture of the paper surface. On the other hand, it is beneficial to neatly cut off the edge of the box body 90 corresponding to the perforation 901 to prevent the edge from being torn due to large paper surface pressure. Optionally, the angle α between the inclined surface 341 and the length direction of the punching member 34 can be 70°, 80°, 85°, etc., and the appropriate angle of the inclined surface 341 can be selected according to material differences.

[0067] In an embodiment of the present application, please refer to Figures 4 to 6 , an installation hole is formed on the support seat 32, and one end of the punching member 34 is inserted into the installation hole in a matching manner; a threaded hole communicating with the installation hole is formed at the top of the support seat 32, and a locking bolt for locking the punching member 34 is installed in the threaded hole; a limiting ring 342 is provided in the middle of the punching member 34, and the limiting ring 342 can conveniently limit the depth of insertion of the punching member 34 into the installation hole, facilitating the installation of the punching member 34.

[0068] In an embodiment of the present application, please refer to Figures 3 to 6 , when the first driver 35 drives the support seat 32 away from the first positioning seat 20: the range of the distance L between the free end of the punching member 34 and the abutting surface of the abutting member 31 is 0.2 mm - 10 mm, which can be understood as the vertical distance between the punching member 34 and the box body 90 when the abutting surface of the abutting member 31 just contacts the box body 90. The abutting surface of the abutting member 31 refers to the surface that contacts the box body 90 when the abutting member 31 presses the box body 90. In this way, the time difference between the contact and separation of the abutting member 31 with the punching member 34 and the box body 90 can be controlled when the first driver 35 drives the support seat 32 to approach or move away from the box body 90. Optionally, when the first driver 35 drives the support seat 32 away from the first positioning seat 20: the distance L between the free end of the punching member 34 and the abutting surface of the abutting member 31 is 1 mm, 3 mm, 6 mm or 8 mm. In this way, the time difference between the contact and separation of the abutting member 31 with the punching member 34 and the box body 90 can be controlled.

[0069] In an embodiment of the present application, please refer to Figures 3 to 6 , when the first driver 35 drives the support seat 32 away from the first positioning seat 20: the free end of the punching member 34 is located in the positioning hole 310. That is to say, when the support seat 32 is in the initial position, the free end of the punching member 34 is located in the positioning hole 310. In this way, the movement of the punching member 34 can be guided by the positioning hole 310 to improve the stability of the punching member 34.

[0070] In an embodiment of the present application, please refer to Figures 1 to 3, the abutting member 31 is a plate member. In this way, it can be parallel to the surface of the box body 90 to facilitate flattening the ear portion 93.

[0071] In an embodiment of the present application, please refer to Figures 3 to 6 , a clearance structure is provided on the first positioning seat 20 corresponding to the position of the punching member 34. Optionally, the clearance structure can be a through hole or a slot for avoiding the free end of the punching member 34 when the punching member 34 passes through the box body 90. In this way, the free end of the punching member 34 can be avoided, preventing damage to the punching member 34.

[0072] In an embodiment of the present application, please refer to Figures 3 to 6 , the support seat 32 is slidably connected to the first base 10. In this way, it is beneficial to improve the stability of the support seat 32 during movement. Optionally, a slide rail 38 is installed on the first base 10, and a slider 39 that slidably cooperates with the slide rail 38 is installed on the support seat 32. Through the sliding cooperation of the slide rail 38 and the slider 39, the sliding connection between the support seat 32 and the first base 10 can be realized, and the support seat 32 can be guided to move linearly closer to or away from the first positioning seat 20.

[0073] In an embodiment of the present application, please refer to Figures 3 to 6 , the first driver 35 is a cylinder. In this way, it can control the support seat 32 to move closer to or away from the first positioning seat 20, drive the support seat 32 to move linearly, and has a low cost. Of course, in other embodiments of the present application, the first driver 35 can also adopt other linear drivers, etc., to control the support seat 32 to move linearly.

[0074] In an embodiment of the present application, please refer to Figures 3 to 6 , the number of the punching assemblies 30 is two, and the two punching assemblies 30 are respectively located on opposite sides of the first positioning seat 20. In this way, the two sides of the box body 90 can be punched simultaneously, which is beneficial to improving the processing efficiency, and synchronous punching is conducive to maintaining the stability of the position of the box body 90 during punching.

The second positioning seat 51 and the second base 54 are connected to the machine table 40, and the power output end of the second driver 53 is connected to the ear picking block 52. When the box body 90 is placed on the second positioning seat 51, the second driver 53 drives the ear picking block 52 to push the ear part 93 to bend towards the lower edge of the surrounding plate 92, so that the ear picking function can be realized, so that the ear part 93 is attached to the surfaces of the surrounding plate 92 and the surrounding frame 91.

[0078] Optionally, the number of the ear picking mechanisms 50 is two, and the two ear picking mechanisms 50 are respectively located on opposite sides of the second positioning seat 51. In this way, the ear parts 93 on both sides of the box body 90 can be processed simultaneously, which is beneficial to improving the efficiency and maintaining the stability of the position of the box body 90 on the second positioning seat 51.
