Description

Technical Field

[0001] This invention relates to the field of corrugated cardboard processing technology, and in particular to a convenient automatic clamp. Background Technology

[0002] A paper feeder is a device that transports paper into processing equipment for operations such as spraying, drying, or cutting. Paper feeders are typically installed at the inlet of the processing equipment, and clamps are used to secure the paper as it enters the equipment.

[0003] Chinese Patent Publication No. CN112356058A, published on 20210212, discloses an automated clamp, including a fixed base, two clamping blocks slidably disposed below the fixed base, a rigid suction cup disposed on the opposite side of the clamping blocks, and a first driving mechanism for driving the clamping blocks to move closer or further apart. An air pressure regulating mechanism is provided between the rigid suction cup and the clamping blocks. The air pressure regulating mechanism includes an air collecting pipe extending from the end of the rigid suction cup near the clamping block and fixed on the clamping block, a piston that is sealed and slidably fitted to the inner wall of the air collecting pipe, a pull rod protruding from the side of the piston away from the rigid suction cup, a mounting block having a groove and allowing the end of the pull rod away from the piston to extend and retract within the groove, an electromagnet fixed at the bottom of the groove, and a reset spring fixed between the electromagnet and the pull rod.

[0004] Existing automatic clamps, such as those mentioned above, mostly use drive components to move two sets of clamping plates relative to each other, thereby achieving centering and clamping of objects. However, in the actual implementation during cardboard processing, both sets of clamping plates are integral structures, and the cardboard is stacked upwards. Although the two sets of clamping plates can achieve cardboard clamping and horizontal alignment, there is still misalignment at the longitudinal ends of the cardboard. The two sets of clamping plates cannot achieve longitudinal alignment of the cardboard, which increases the limitations of the automatic clamp. Therefore, it is urgent to propose a corresponding convenient automatic clamp to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a convenient automatic clamp in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A portable automatic clamp includes a housing, a drive assembly, and a clamping plate. A U-shaped side frame is fixedly installed on the outer wall of the clamping plate. A push bar is slidably connected to the inner wall of the clamping plate. A reset assembly for resetting the push bar is provided between the push bar and the side frame. A moving rod is slidably connected to the inner wall of the longitudinal end of the clamping plate. A crossbar is fixedly installed on the front end face of the moving rod. A tapping rod is fixedly installed on one side of the crossbar. The clamping plate also includes a linkage mechanism for linking the moving rod and the push bar. The linkage mechanism includes a toothed ring, a toothed block, and a connecting assembly for synchronous movement of the toothed block and the push bar. The toothed ring is movably installed on the inner wall of the clamping plate. The toothed ring is meshed with the toothed block, and a screw fixedly connected to the moving rod is screwed onto the inner wall of the toothed ring.

[0008] Preferably, a connecting sleeve is fixedly installed on the outer wall of the longitudinal end of the movable rod, the inner wall of the connecting sleeve is slidably connected to the outer wall of the crossbar, and the inner wall of the connecting sleeve is provided with a positioning component for positioning the crossbar.

[0009] Preferably, the positioning component includes a locking rod, the outer wall of the locking rod being screwed into the inner wall of the connecting sleeve, and the open end of the locking rod abutting against the outer wall of the crossbar.

[0010] Preferably, the movable rod has a rectangular cross-section, and a limiting piece is fixedly installed on the side of the crossbar away from the racket handle.

[0011] Preferably, the reset assembly includes a spring, which is fixedly installed between the push bar and the side frame, and the push bar is slidably connected to the inner wall of the clamping plate through a mating groove.

[0012] Preferably, an L-shaped connecting seat is fixedly installed on the top of the clamping plate, and the connecting seat is fixedly engaged with the drive assembly by fasteners.

[0013] Preferably, an mounting plate is fixedly installed on the inner wall of the clamping plate, and a protruding ring is fixedly installed on the outer wall of the toothed ring. The protruding ring is engaged with the inner wall of the mounting plate through an annular groove.

[0014] Preferably, the connecting assembly includes a connecting rod, which is fixedly connected to the toothed block, and the connecting rod is slidably connected to the inner wall of the clamping plate through a horizontally set transverse groove.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0016] 1. In this application, after the cardboard is stacked under the housing, the drive assembly drives two sets of clamping plates to move relative to each other. The push bar on the inner surface of the clamping plate first contacts the outer surface of the horizontal end of the cardboard. As the clamping plate moves, it gradually becomes flush with the clamping plate and compresses the spring, thereby achieving clamping and horizontal alignment of the cardboard. During this process, the connecting rod on the outer surface of the push bar slides along the transverse groove. The connecting rod is linked to the toothed block, which drives the toothed ring to rotate for a specified period. The convex ring on the outer surface of the toothed ring slides along the annular groove on the inner surface of the mounting plate, thereby making it rotate stably while keeping its vertical position unchanged. The inner surface of the toothed ring is screwed into the screw. The movable rod with a rectangular cross-section and the clamping plate restrict the axial movement of the screw, so that the screw stably pulls the movable rod. The movable rod is linked to the tapping rod through the connecting sleeve and the crossbar, so that the tapping rod engages with the outer surface of the longitudinal end of the cardboard. The tapping rod will perform longitudinal alignment of the cardboard in this process. Through the clamping plate and the tapping rod, the cardboard is clamped and the horizontal and longitudinal alignment of the cardboard is achieved at the same time. This makes the automatic fixture more in line with the processing requirements of the cardboard and ensures the effectiveness of the automatic fixture.

[0017] 2. In this application, the locking rod is rotated so that its open end is disengaged from the outer wall of the crossbar. At this time, the crossbar loses its restraint and the flapper can be moved horizontally. The outer wall of the crossbar slides against the inner wall of the connecting sleeve until the flapper reaches the designated position. Then, the locking rod is rotated counterclockwise so that its open end is pressed tightly against the outer wall of the crossbar. In this way, the crossbar is repositioned by friction. This allows the horizontal position of the flapper to be easily adjusted according to the usage requirements without obstructing the movement of the cardboard to the bottom of the shell.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figure 1-5 The present invention provides a technical solution:

[0027] A convenient automatic clamp includes a housing 1, a drive assembly 2, and a clamping plate 4. A U-shaped side frame 5 is fixedly installed on the outer wall of the clamping plate 4. A push bar 12 is slidably connected to the inner wall of the clamping plate 4. A reset assembly for resetting the push bar 12 is provided between the push bar 12 and the side frame 5. A moving rod 10 is slidably connected to the inner wall of the longitudinal end of the clamping plate 4. A crossbar 7 is fixedly installed on the front end face of the moving rod 10. A tapping rod 6 is fixedly installed on one side of the crossbar 7. The clamping plate also includes a linkage mechanism for linkage between the moving rod 10 and the push bar 12. The linkage mechanism includes a toothed ring 17, a toothed block 16, and a connecting assembly for synchronous movement of the toothed block 16 and the push bar 12. The toothed ring 17 is movably installed on the inner wall of the clamping plate 4. The toothed ring 17 is meshed with the toothed block 16, and a screw 15 fixedly connected to the moving rod 10 is screwed onto the inner wall of the toothed ring 17.

[0028] After the cardboard is stacked under the housing 1, the drive assembly 2 drives the two sets of clamping plates 4 to move relative to each other. The push bar 12 on the inner surface of the clamping plate 4 first contacts the outer surface of the horizontal end of the cardboard. As the clamping plate 4 moves, it gradually becomes flush with the clamping plate 4 and compresses the spring 21, thereby achieving clamping and horizontal alignment of the cardboard. During this process, the connecting rod 20 on the outer surface of the push bar 12 slides along the transverse groove 14. The connecting rod 20 is linked to the toothed block 16, which drives the toothed ring 17 to rotate for a specified period. The convex ring 19 on the outer surface of the toothed ring 17 slides along the annular groove on the inner surface of the mounting plate 18, thereby stabilizing its rotation while maintaining a vertical position. The inner wall of the toothed ring 17 remains unchanged and is screwed into the screw 15. The rectangular cross-section of the moving rod 10 and the clamping plate 4 restrict the axial movement of the screw 15, so that the screw 15 stably pulls the moving rod 10. The moving rod 10 is linked to the tapping rod 6 through the connecting sleeve 9 and the crossbar 7, so that the tapping rod 6 is engaged with the longitudinal end outer wall of the cardboard. The tapping rod 6 will perform longitudinal alignment of the cardboard in this process. Through the clamping plate 4 and the tapping rod 6, the cardboard is clamped and the horizontal and longitudinal alignment of the cardboard is completed at the same time. This makes the automatic fixture more in line with the processing requirements of the cardboard and ensures the use effect of the automatic fixture.

[0029] Specifically, such as Figure 2 and Figure 3 As shown, a connecting sleeve 9 is fixedly installed on the outer wall of the longitudinal end of the moving rod 10. The inner wall of the connecting sleeve 9 is slidably connected to the outer wall of the crossbar 7, and the inner wall of the connecting sleeve 9 is provided with a positioning component for positioning the crossbar 7. Rotating the locking rod 8 causes its open end to disengage from the outer wall of the crossbar 7. At this time, the crossbar 7 loses its constraint and can move the flapper 6. The outer wall of the crossbar 7 and the inner wall of the connecting sleeve 9 slide together until the flapper 6 reaches the designated position. Then, the locking rod 8 is rotated counterclockwise so that its open end is pressed tightly against the outer wall of the crossbar 7. In this way, the crossbar 7 is repositioned by friction. This allows the horizontal position of the flapper 6 to be easily adjusted according to the usage requirements without obstructing the movement of the cardboard to the bottom of the housing 1.

[0030] Specifically, such as Figure 2 and Figure 3 As shown, the positioning assembly includes a locking rod 8, the outer wall of the locking rod 8 is screwed to the inner wall of the connecting sleeve 9, and the open end of the locking rod 8 abuts against the outer wall of the crossbar 7. The positioning of the crossbar 7 is achieved by the friction generated by the locking rod 8, which can ensure the stability of the crossbar 7 and the convenience of the positioning and separation process. The moving rod 10 has a rectangular cross-section to limit the axial deflection of the screw 15. A limiting piece 11 is fixedly installed on the side of the crossbar 7 away from the flap 6 to prevent the crossbar 7 from completely detaching from the connecting sleeve 9.

[0031] Specifically, such as Figure 1 and Figure 4As shown, the reset assembly includes a spring 21, which is fixedly installed between the push bar 12 and the side frame 5. The push bar 12 is slidably connected to the inner wall of the clamping plate 4 through a mating groove 13. The mating groove 13 ensures the smooth movement of the push bar 12 and avoids the longitudinal offset of the spring 21. After the clamping plate 4 is separated from the cardboard, the push bar 12 will be stably reset under the action of the spring 21. An L-shaped connecting seat 3 is fixedly installed on the top of the clamping plate 4. The connecting seat 3 is fixedly engaged with the drive assembly 2 through fasteners, thereby ensuring the ease of disassembly and assembly of the clamping plate 4.

[0032] Specifically, such as Figure 4 and Figure 5 As shown, an mounting plate 18 is fixedly installed on the inner wall of the clamping plate 4, and a protruding ring 19 is fixedly installed on the outer wall of the toothed ring 17. The protruding ring 19 is engaged with the inner wall of the mounting plate 18 through an annular groove. The protruding ring 19 on the outer wall of the toothed ring 17 slides along the annular groove on the inner wall of the mounting plate 18, thereby making it rotate stably while keeping its vertical position unchanged. The connecting component includes a connecting rod 20, which is fixedly connected to the toothed block 16. The connecting rod 20 is slidably connected to the inner wall of the clamping plate 4 through a horizontally set transverse groove 14, which realizes the linkage between the push bar 12 and the toothed block 16 while ensuring the stability of the position of the toothed block 16.

[0033] Working principle: After the cardboard is stacked under the housing 1, the drive assembly 2 drives the two sets of clamping plates 4 to move relative to each other. The push bar 12 on the inner wall of the clamping plate 4 first contacts the outer wall of the horizontal end of the cardboard. As the clamping plate 4 moves, it gradually becomes flush with the clamping plate 4 and compresses the spring 21, thereby achieving clamping and horizontal alignment of the cardboard. During this process, the connecting rod 20 on the outer wall of the push bar 12 slides along the transverse groove 14. The connecting rod 20 is linked to the toothed block 16, which drives the toothed ring 17 to rotate for a specified period. The convex ring 19 on the outer wall of the toothed ring 17 slides along the annular groove on the inner wall of the mounting plate 18, so that it rotates stably while keeping its vertical position unchanged. The inner wall of the toothed ring 17 is screwed into the screw 15. The rectangular cross-section moving rod 10 and the clamping plate 4 restrict the axial movement of the screw 15, so that the screw 15 stably pulls the moving rod 10. The moving rod 10 is connected to the connecting sleeve 9. The linkage between the crossbar 7 and the flapper 6 causes the flapper 6 to engage with the longitudinal end outer wall of the cardboard. During this process, the flapper 6 aligns the cardboard longitudinally. Through the clamping plate 4 and the flapper 6, the cardboard is clamped while simultaneously achieving horizontal and longitudinal alignment. This makes the automatic fixture more closely fit the processing requirements of the cardboard, ensuring the effectiveness of the automatic fixture. Rotating the locking rod 8 causes its open end to disengage from the outer wall of the crossbar 7. At this point, the crossbar 7 loses its restraint and the flapper 6 can be moved horizontally. The outer wall of the crossbar 7 slides against the inner wall of the connecting sleeve 9 until the flapper 6 reaches the designated position. Then, rotating the locking rod 8 counterclockwise causes its open end to press tightly against the outer wall of the crossbar 7. This uses friction to reposition the crossbar 7, allowing the horizontal position of the flapper 6 to be easily adjusted according to usage requirements without obstructing the movement of the cardboard to the bottom of the housing 1.
