Description

Technical Field

[0001] This utility model relates to the field of box-making machine technology, and in particular to an embedded box-pressing device. Background Technology

[0002] Among existing patents, Chinese patent application number 202411621935.1 discloses a fully automatic molding production line for lid and top boxes. It discloses an upper mold mechanism comprising a Z-axis slide block disposed on the top of the frame, a Z-axis sliding plate slidably connected to the Z-axis slide block along the Z-axis direction, a Z-axis linear drive mechanism disposed on the Z-axis slide block and drivenly connected to the Z-axis sliding plate, a Z-axis slider slidably connected to the Z-axis sliding plate along the Z-axis direction, a Z-axis drive motor disposed on the top of the Z-axis sliding plate and connected to the Z-axis slider via a lead screw, a mold assembly, and a pusher assembly. The mold assembly includes a first longitudinal connecting rod fixedly connected to both sides of the bottom of the Z-axis slider, and a forming mold fixedly connected between the bottom ends of the two first longitudinal connecting rods. Vacuum holes are provided on both side walls of the forming mold. The mold assembly also includes a second longitudinal connecting rod fixedly connected to the bottom of the Z-axis slide plate, and a push plate fixedly connected to the bottom end of the second longitudinal connecting rod. A receiving groove matching the push plate is provided at the bottom of the forming mold, and a first through hole communicating with the receiving groove is provided at the top of the forming mold. The second longitudinal connecting rod is movably disposed in the first through hole. The lead screw and the first longitudinal connecting rod of this upper mold mechanism are relatively long. This increases the manufacturing cost and makes disassembly and assembly of the long lead screw and the first longitudinal connecting rod inconvenient. Furthermore, the long first longitudinal connecting rod is prone to bending or wobbling during lifting and lowering, making it difficult to ensure operational stability. Therefore, the defects are obvious, and a solution is urgently needed. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide an embedded pressing box device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An embedded pressing box device includes a mounting box with an internal mounting cavity. The top and bottom surfaces of the mounting box have sliding holes communicating with the mounting cavity. A first rotary actuator is mounted on the outer wall of the mounting box. A transmission gear is fitted onto the rotating shaft of the first rotary actuator, and the transmission gear is rotatably mounted within the mounting cavity. A sliding plate is slidably connected to the mounting box, and a rack is mounted on one side of the sliding plate. Both the sliding plate and the rack slide through the sliding holes and the mounting cavity. The transmission gear meshes with the rack for transmission. A drive shaft and a lead screw are embeddedly and rotatably connected to the sliding plate from top to bottom. A second rotary actuator is mounted at the top of the sliding plate. The actuator, the rotating shaft of the second rotary drive is coaxially driven and connected to the top end of the transmission shaft, the top end of the lead screw is coaxially connected to the bottom end of the transmission shaft via a coupling, the bottom end of the slide plate is equipped with a middle mold rod, the bottom end of the middle mold rod is equipped with a middle mounting plate, the bottom side of the slide plate is recessed with a lifting cavity, the lead screw is located in the lifting cavity, the lead screw is threaded with a nut, the nut is slidably connected to the inner side wall of the lifting cavity, the bottom of the slide plate is slidably connected with a guide rod, the top end of the guide rod is connected to the nut, the bottom end of the guide rod is equipped with an upper mounting plate, the middle mold rod slides through the upper mounting plate, the upper mounting plate is located above the middle mounting plate.

[0006] Furthermore, the inner wall of the mounting cavity is equipped with a lubricating element for lubricating the transmission gears and / or racks.

[0007] Furthermore, the lubricating component is a felt-lubricated gear, which is rotatably connected to the inner wall of the mounting cavity and meshes with the transmission gear for transmission.

[0008] Furthermore, the bottom end of the skateboard is recessed with a guide hole, which is connected to the lifting cavity, and the guide rod slides through the guide hole.

[0009] Furthermore, a slider is fitted around the nut, and a slide rail is provided on the inner wall of the lifting cavity, with the slider and the slide rail slidingly engaged.

[0010] Furthermore, the side wall of the skateboard is equipped with a guide rail, which slides through the slide hole and the mounting cavity. The inner wall of the slide hole and / or the inner wall of the mounting cavity is equipped with a guide block, and the guide rail and the guide block slide together.

[0014] The beneficial effects of this utility model are as follows: In practical applications, the first rotary driver drives the transmission gear to rotate. The rotating transmission gear meshes with the rack, causing the rack to drive the slide plate, the middle mounting plate, and the upper mounting plate to rise and fall synchronously relative to the mounting box. After the middle mounting plate falls to the desired position, the second rotary driver drives the transmission shaft and the lead screw to rotate coaxially in the forward direction. The forward-rotating lead screw drives the nut to rise along the lifting cavity to the desired height, thereby causing the upper mounting plate to rise to the desired height. When the upper mounting plate rises to the desired height, the second rotary driver drives the transmission shaft and the lead screw to rotate coaxially in the reverse direction until the upper mounting plate falls to the desired height. This utility model coaxially embeds the transmission shaft and the lead screw inside the slide plate, and positions the lead screw below the transmission shaft, so that the lead screw is located at the bottom of the slide plate. This effectively shortens the length of the lead screw and the guide rod, making the guide rod less prone to bending or shaking during the lifting process, improving the stability of the guide rod and the upper mounting plate lifting, facilitating the installation of the lead screw and the guide rod, and reducing the manufacturing cost of the lead screw and the guide rod.

[0020] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0021] like Figures 1 to 3As shown, this utility model provides an embedded pressing box device, which includes a mounting box 1. The mounting box 1 has an mounting cavity 2 inside. The top and bottom surfaces of the mounting box 1 are provided with sliding holes 3 communicating with the mounting cavity 2. A first rotation driver 4 is installed on the outer wall of the mounting box 1. The rotation shaft of the first rotation driver 4 is fitted with a transmission gear 5. The transmission gear 5 is rotatably disposed in the mounting cavity 2. A sliding plate 6 is slidably connected to the mounting box 1. A rack 7 is installed on one side of the sliding plate 6. The sliding plate 6 and the rack 7 slide through the sliding holes 3 and the mounting cavity 2. The transmission gear 5 meshes with the rack 7 for transmission. The sliding plate 6 is embeddedly rotatably connected from top to bottom to a transmission shaft 8 and a lead screw 9. A second rotation driver 10 is installed at the top of the sliding plate 6. The rotation shaft of the second rotation driver 10 is connected to the transmission shaft 8 and the lead screw 9. The top end of the drive shaft 8 is coaxially driven, and the top end of the lead screw 9 is coaxially connected to the bottom end of the drive shaft 8 via the coupling 11. The bottom end of the slide plate 6 is equipped with a middle mold rod 12, and the bottom end of the middle mold rod 12 is equipped with a middle mounting plate 13. The bottom side of the slide plate 6 is recessed with a lifting cavity 14, and the lead screw 9 is located in the lifting cavity 14. The lead screw 9 is threaded with a nut 15, and the nut 15 is slidably connected to the inner wall of the lifting cavity 14. The bottom of the slide plate 6 is slidably connected with a guide rod 16, the top end of the guide rod 16 is connected to the nut 15, and the bottom end of the guide rod 16 is equipped with an upper mounting plate 17. The middle mold rod 12 slides through the upper mounting plate 17, and the upper mounting plate 17 is located above the middle mounting plate 13. Specifically, both the first rotary driver 4 and the second rotary driver 10 can be motors.

[0022] In practical applications, the first rotary driver 4 drives the transmission gear 5 to rotate. The rotating transmission gear 5 meshes with the rack 7, causing the rack 7 to drive the slide plate 6, the middle mounting plate 13, and the upper mounting plate 17 to rise and fall synchronously relative to the mounting box 1. After the middle mounting plate 13 falls to the required position, the second rotary driver 10 drives the transmission shaft 8 and the lead screw 9 to rotate coaxially in the forward direction. The forward-rotating lead screw 9 drives the nut 15 to rise along the lifting cavity 14 to the required height position, thereby causing the upper mounting plate 17 to rise to the required height position. When the upper mounting plate 17 rises to the required height position, the second rotary driver 10 drives the transmission shaft 8 and the lead screw 9 to rotate coaxially in the reverse direction until the upper mounting plate 17 falls to the required height position. This invention coaxially embeds the drive shaft 8 and the lead screw 9 inside the slide plate 6, and positions the lead screw 9 below the drive shaft 8, so that the lead screw 9 is located at the bottom of the slide plate 6. This effectively shortens the length of the lead screw 9 and the guide rod 16, making the guide rod 16 less prone to bending or shaking during lifting and lowering, improving the stability of the lifting and lowering of the guide rod 16 and the upper mounting plate 17, facilitating the installation of the lead screw 9 and the guide rod 16, and reducing the production and manufacturing costs of the lead screw 9 and the guide rod 16.

[0023] In this embodiment, a lubricating element 18 is installed on the inner wall of the mounting cavity 2. The lubricating element 18 is used to lubricate the transmission gear 5 and / or the rack 7. By lubricating the transmission gear 5 and the rack 7 with the lubricating element 18, friction and wear are reduced, service life is extended, and the lifting and lowering of the slide plate 6 and the rack 7 is smoother.

[0024] In this embodiment, the lubricating element 18 is a felt lubricating gear, which is rotatably connected to the inner wall of the mounting cavity 2 and meshes with the transmission gear 5 for transmission. This structural design facilitates the lubrication of the transmission gear 5.

[0025] In this embodiment, the bottom end of the slide plate 6 is recessed with a guide hole that communicates with the lifting cavity 14, and the guide rod 16 slides through the guide hole. During the lifting and lowering process of the guide rod 16, the guide hole guides the guide rod 16, improving the stability of the lifting and lowering of the guide rod 16, and the setting of the guide hole facilitates the fixed connection between the guide rod 16 and the nut 15.

[0026] In this embodiment, a slider 19 is fitted around the nut 15, and a slide rail 20 is provided on the inner wall of the lifting cavity 14. The slider 19 and the slide rail 20 are in sliding engagement. During the process of the nut 15 rising and falling within the lifting cavity 14, the sliding engagement between the slider 19 and the slide rail 20 improves the stability of the nut 15 and the guide rod 16 rising and falling.

[0027] In this embodiment, a guide rail 21 is installed on the side wall of the slide plate 6. The guide rail 21 slides through the slide hole 3 and the mounting cavity 2. A guide block is installed on the inner wall of the slide hole 3 and / or the inner wall of the mounting cavity 2. The guide rail 21 and the guide block slide in cooperation. During the lifting and lowering of the slide plate 6, the guide rail 21 and the guide block slide in cooperation, which improves the stability and smoothness of the lifting and lowering of the slide plate 6 and the rack 7.

[0028] In this embodiment, a guide member 23 is embedded in the guide hole, and the guide rod 16 slides through the guide member 23; preferably, the guide member 23 is a copper sleeve. The guide member 23 has good wear resistance and is not easily worn.

[0029] In this embodiment, the mounting box 1 is equipped with a sensor 24, and the slide plate 6 is embedded with a trigger block. The trigger block is used to trigger the sensor 24. The sensor 24 is electrically connected to the first rotary driver 4 and the second rotary driver 10, respectively. Specifically, there are two trigger blocks, which are arranged on the slide plate 6 from top to bottom in a straight line. When the slide plate 6 rises or falls to the required height, the trigger block will trigger the sensor 24. The sensor 24 will then send feedback signals to the first rotary driver 4 and the second rotary driver 10, respectively, causing the first rotary driver 4 and the second rotary driver 10 to start according to the program.

[0030] In this embodiment, a displacement sensor is installed on the top wall of the mounting cavity 2. The sensing end of the displacement sensor abuts against the top of the nut 15, and the displacement sensor is electrically connected to the second rotary driver 10. The displacement sensor is used to monitor the lifting and lowering displacement of the nut 15 in real time. When the displacement sensor detects that the nut 15 has moved to the highest or lowest position, the displacement sensor sends a feedback signal to the second rotary driver 10, causing the second rotary driver 10 to stop working or reverse drive, so as to ensure that the required action is completed.

[0031] Furthermore, a lubrication ring is installed on the top and / or bottom surface of the mounting box 1. The lubrication ring is located outside (above and / or below) the sliding hole 3 and is sleeved on the slide plate 6 and rack 7. The lubrication ring is used to lubricate the slide plate 6 and rack 7, reducing the frictional resistance of the slide plate 6 and rack 7, making the lifting and lowering of the slide plate 6 and rack 7 smoother, with a low failure rate and long service life. In addition, since the lubrication ring is sleeved on the slide plate 6 and rack 7, it also plays a role in dust prevention.

[0032] Furthermore, the lubrication ring includes a roughly square or U-shaped ring body. The square sliding plate 6 and rack 7 slide through the central hole of the ring body. The interior of the ring body is provided with a receiving cavity for containing lubricating oil. The upper part of the ring body is provided with an opening communicating with the receiving cavity. A ring covering the opening is provided on the upper part of the ring body. Several balls are evenly embedded on the inner wall of the ring body. The balls can rotate freely on the inner wall of the ring body. One side of the ball protrudes outside the inner wall of the ring body, and the other side of the ball extends into the receiving cavity. That is, the outer side of the ball protrudes from the two sides of the inner wall. A retaining ring is threaded on the outer side of the ring body. The lower end face of the retaining ring is an inclined surface with a higher inner side and a lower outer side. Several lateral pressure columns are evenly passed through the outer wall of the ring body. The lateral pressure columns extend radially along the ring body. One end of the lateral pressure columns extends into the receiving cavity of the ring body. The other end of the lateral pressure columns abuts against the inclined surface of the retaining ring. Several balls roll and abut against the outer sides of the sliding plate 6 and rack 7 respectively.

[0033] In practical applications, during use, both the slide plate 6 and the rack 7 pass through the ring body. During the lifting and lowering of the slide plate 6 and rack 7, they respectively come into rolling contact with the balls, which carry the lubricating oil out of the receiving cavity. When the remaining lubricating oil in the receiving cavity is low, rotating the retaining ring downwards utilizes the lower inclined surface of the retaining ring to press the lateral pressure column inwards. This lateral pressure column increases the air pressure in the receiving cavity, allowing the lubricating oil to overflow more quickly and fully from the balls. The lubricating oil is then adhered to the slide plate 6 and rack 7 by the balls, or the overflowing lubricating oil directly adheres to the slide plate 6 and rack 7, thus achieving lubrication of the slide plate 6 and rack 7. Furthermore, the ball bearing design improves the lifting and lowering stability of the slide plate 6 and rack 7.

[0034] All technical features in this embodiment can be freely combined according to actual needs.

[0035] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
