Description

Technical Field

[0001] This utility model relates to the field of nailing machine technology, specifically to a material blocking adjustment mechanism for a nailing machine. Background Technology

[0002] A carton stapling machine is an automated device that staples the edges of two pieces of cardboard together (similar in principle to a stapler) to form a folded carton. Unfolding the folded carton creates a box-shaped carton with a cavity. The carton stapling machine mainly consists of a frame and a cardboard conveying mechanism mounted on the frame. The cardboard conveying mechanism has a first conveying mechanism and a second conveying mechanism, with a stapling head mechanism located between the first and second conveying mechanisms.

[0003] The nailing mechanism has a nailing component and a material blocking component. The nailing component can nail multiple pieces of cardboard to fix them. The material blocking component has a baffle and a material blocking drive unit. Before nailing, the baffle abuts against the front end of the cardboard to block the cardboard from moving forward, achieving initial positioning of the cardboard. After the initial positioning is completed, the baffle releases the cardboard, allowing the cardboard to move forward to the next station while being nailed. Since the initial nailing position of cardboard of different sizes is different, it is necessary to adjust the front and rear positions of the baffle. However, the traditional method is to adjust it manually, which is inefficient and has poor precision. Utility Model Content

[0004] This utility model addresses the deficiencies in existing technologies by providing a baffle adjustment mechanism for a nailing machine. It employs a lead screw and motor drive structure to automatically adjust the front and rear positions of the baffle, achieving high adjustment efficiency and accuracy.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A material blocking adjustment mechanism for a carton stapler includes a base, and a material blocking assembly and an adjustment assembly disposed on the base. The material blocking assembly has a baffle and a material blocking drive unit. The baffle is located in front of the nailing assembly on the carton stapler. The material blocking drive unit can drive the baffle to move so that the baffle blocks or allows the cardboard to pass. The adjustment assembly has a movable seat, a lead screw, and a servo motor. The movable seat is slidably connected to the base. The baffle and the material blocking drive unit are both disposed on the movable seat. The servo motor can drive the movable seat to move back and forth through the lead screw to adjust the front and rear position of the baffle relative to the nailing assembly.

[0007] By setting an adjustment assembly consisting of a movable seat, a lead screw, and a servo motor, the movable seat is slidably connected to the machine base. The baffle and the material blocking drive unit are both located on the movable seat. The servo motor drives the movable seat to move back and forth through the lead screw, thereby adjusting the front and back position of the baffle relative to the nailing assembly to adapt to the positioning requirements of cardboard of different sizes. Thus, the drive structure of lead screw + motor realizes the automatic adjustment of the front and back position of the baffle, with high adjustment efficiency and good accuracy.

[0008] In one embodiment, the movable seat is provided with a support member located behind the baffle plate. When the baffle plate is in the release state, the upper edge of the support member is higher than the upper edge of the baffle plate.

[0009] In one embodiment, the support member has a connecting plate and a guide plate, the connecting plate being connected to the movable seat and the upper end of the guide plate being connected, the guide plate extending obliquely downwards away from the baffle.

[0010] In one embodiment, the angle β between the guide plate and the horizontal plane is less than or equal to 45°.

[0011] In one embodiment, a support plate is connected between the uppermost end of the connecting plate and the uppermost end of the guide plate, and the support plate is arranged in a horizontally extending manner.

[0012] In one embodiment, the base is provided with a slide rail extending forward and backward, and the movable seat is slidably connected to the slide rail by a slider.

[0013] In one embodiment, a mounting groove is recessed on one side wall of the base, and the lead screw is disposed in the mounting groove.

[0014] In one embodiment, the material blocking drive unit drives the baffle to move up and down.

[0015] In one embodiment, the baffle is slidably connected to the movable seat via a guide rod.

[0016] In one embodiment, the lower end of the baffle is provided with a mounting plate, and the driving end of the material blocking drive unit and the upper end of the guide rod are both connected to the mounting plate.

[0017] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, by setting an adjustment component consisting of a movable seat, a lead screw, and a servo motor, the movable seat is slidably connected to the machine base. The baffle and the material blocking drive unit are both located on the movable seat. The servo motor drives the movable seat to move back and forth through the lead screw, thereby adjusting the front and back position of the baffle relative to the nailing component to adapt to the positioning requirements of cardboard of different sizes. Thus, the drive structure of lead screw + motor realizes the automatic adjustment of the front and back position of the baffle, with high adjustment efficiency and good accuracy.

Detailed Implementation

[0027] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "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 the utility model and simplifying the description, and do not indicate or imply that the position 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] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] like Figure 1-6As shown, this utility model discloses a material blocking adjustment mechanism for a nailing machine, including a base 10 and a material blocking assembly 30 disposed on the base 10. The material blocking assembly 30 has a baffle 31 and a material blocking drive unit 32. The baffle 31 is located in front of the nailing assembly 20 on the nailing machine. The material blocking drive unit 32 can drive the baffle 31 to move so that the baffle 31 blocks or allows the cardboard 50 to pass. The nailing assembly 20 can nail and fix multiple pieces of cardboard 50. The nailing assembly 20 is a mature existing technology, so its internal structure will not be described in detail.

[0030] The base 10 is also provided with an adjustment component 40, which has a movable seat 41, a lead screw 42 and a servo motor 43. The movable seat 41 is slidably connected to the base 10. The baffle 31 and the material blocking drive unit 32 are both provided on the movable seat 41, and both the baffle 31 and the material blocking drive unit 32 can move with the movable seat 41. The servo motor 43 can drive the movable seat 41 to move back and forth through the lead screw 42 to adjust the front and rear position of the baffle 31 relative to the nailing component 20.

[0031] The movable seat 41 is provided with a support member 33, which is located behind the baffle plate. When the baffle plate 31 is in the release state, the upper edge of the support member 33 is higher than the upper edge of the baffle plate. It should be noted that the baffle plate 31 is in the release state when the baffle plate 31 is driven to move down to the lowest point by the baffle driving unit 32. By setting the support member 33, which is located behind the baffle plate, and with the upper edge of the support member 33 higher than the upper edge of the baffle plate when the baffle plate 31 is in the release state, the support member 33 supports the lower surface of the cardboard 50, preventing the front edge of the cardboard 50 from sagging due to gravity. This avoids the cardboard 50 from colliding with the baffle plate 31 during its forward movement, allowing the cardboard 50 to smoothly pass over the baffle plate 31 and continue moving forward to the next station with good stability.

[0032] The support member 33 has a connecting plate 331 and a guide plate 332. The lower end of the connecting plate 331 is connected to the movable seat 41, and the upper end of the connecting plate 331 is connected to the upper end of the guide plate 332. The guide plate 332 extends obliquely from top to bottom away from the baffle 31. By setting the support member 33 composed of the connecting plate 331 and the guide plate 332, the connecting plate 331 is used to connect the movable seat 41 to facilitate the installation of the support member 33. The obliquely extending guide plate 332 is used to guide the front edge of the cardboard 50, so that the cardboard 50 can move forward smoothly.

[0033] The angle β between the guide plate 332 and the horizontal plane is less than or equal to 45°; the angle β between the guide plate 332 and the horizontal plane is less than or equal to 45°, which can provide a better guiding effect on the front edge of the cardboard 50.

[0034] A support plate 333 is connected between the uppermost end of the connecting plate 331 and the uppermost end of the guide plate 332. The support plate 333 extends horizontally. Specifically, the connecting plate 331, the support plate 333, and the guide plate 332 are integrally bent and formed.

[0035] The base 10 is provided with a slide rail 11 extending forward and backward, and the movable seat 41 is slidably connected to the slide rail 11 by a slider.

[0036] The machine base 10 has a recessed mounting groove 12 on one side wall, and the lead screw 42 is located in the mounting groove 12. By arranging the lead screw 42 in the mounting groove 12, the internal space of the machine base 10 is made reasonable and the structure is compact.

[0037] The material blocking drive unit 32 drives the baffle 31 to move up and down. Specifically, the material blocking drive unit 32 can be a cylinder.

[0038] The baffle 31 is slidably connected to the movable seat 41 via the guide rod 35; by setting the guide rod 35, the baffle 31 has good stability when sliding up and down.

[0039] The lower end of the baffle 31 is provided with a mounting plate 34. The driving end of the material blocking drive unit 32 and the upper end of the guide rod 35 are both connected to the mounting plate 34. Specifically, there are two guide rods 35, and the material blocking drive unit 32 is located between the two guide rods 35.

[0040] It should be noted that the baffle 31 of this utility model is movable up and down, or the baffle 31 can be set to be flipped, in which case the rotation center axis of the baffle 31 extends in the left and right direction.

[0041] It should also be noted that the nailing component 20 of this utility model can be installed on the base 10 or on other parts of the nailing machine.

[0042] The working principle of this utility model is as follows: After the double-layered cardboard 50 passes through the nailing assembly 20, it continues to move forward. When the front end of the cardboard 50 abuts against the baffle 31, the baffle 31 positions the cardboard 50. Then, the material blocking drive unit 32 drives the baffle 31 to move down and release the cardboard 50. While the nailing assembly 20 fixes the double-layered cardboard 50 with connecting nails, the cardboard 50 moves forward past the support member 33 and the baffle 31 to the next station, completing the nailing operation.

[0043] In summary, this utility model, by setting an adjustment component 40 consisting of a movable seat 41, a lead screw 42, and a servo motor 43, allows the movable seat 41 to be slidably connected to the machine base 10. The baffle 31 and the material blocking drive unit 32 are both located on the movable seat 41. The servo motor 43 drives the movable seat 41 to move back and forth through the lead screw 42, thereby adjusting the front and rear position of the baffle 31 relative to the nailing component 20 to adapt to the positioning requirements of cardboard 50 of different sizes. Thus, the drive structure of the lead screw 42 and the motor achieves automated adjustment of the front and rear position of the baffle 31, with high adjustment efficiency and good precision.

[0044] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc., made to the above embodiments based on the actual technical aspects of the present utility model shall still fall within the scope of the technical solution of the present utility model.
