Description

Technical Field

[0001] This utility model relates to the field of pencil manufacturing technology, specifically to a high-efficiency pencil board bundle clamping frame. Background Technology

[0002] Pencils are the most commonly used writing tool for elementary school students, art students, and draftsmen. They mainly consist of three parts: the lead, the barrel, and the barrel coating. In the pencil production process, pencil boards need to be clamped and pressed to ensure adhesion. After pressing, the clamps need to be removed. Existing pencil board clamping frames require continuous external pressure equipment to maintain pressure during the pressing process. This makes movement of the clamping frame inconvenient and occupies equipment space. Furthermore, because the pressing process takes a long time, the pressure equipment is occupied for extended periods, affecting overall production efficiency. Utility Model Content

[0003] The purpose of this invention is to address the problem that existing pencil board clamping frames occupy pressurizing equipment and space, thus affecting overall production efficiency.

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

[0005] A high-efficiency pencil board clamping frame is characterized by comprising a frame body, wherein at least two sets of guide rods are connected between the two ends of the frame body in the width direction, and a clamping plate for clamping pencil boards is slidably connected to one end of each set of guide rods; and a pressure-holding component and a pressure-holding locking component are installed on one end of the frame body located on the clamping plate.

[0006] The pressure-holding and locking assembly includes a sliding bushing installed on one end of the frame located on the clamping plate. A fixing bolt through groove is provided in the middle of the sliding bushing. A hinge seat is installed on the end of the sliding bushing away from the clamping plate. An L-shaped fixing bolt is rotatably connected to the hinge seat. A locking block is provided on the short side end of the fixing bolt and extends into the fixing bolt through groove. An inclined surface is provided on the upper surface of the long side of the fixing bolt for easy release by cooperating with the pressure release block. A second return spring is connected between the upper surface of the fixing bolt and the lower end of the hinge seat.

[0007] The pressure-holding assembly includes a pressure-holding top rod that is slidably sleeved in a sliding bushing. A baffle is fixedly connected to the end of the pressure-holding top rod away from the clamping plate. A first return spring is sleeved on the portion of the pressure-holding top rod between the baffle and the hinge seat. Several unidirectional conical steps are evenly spaced in the middle of the pressure-holding top rod, and a unidirectional groove is formed between adjacent unidirectional conical steps to cooperate with the locking block of the fixing bolt.

[0008] A further improvement is that limiting collars for limiting the sliding bushing and the hinge seat are fixedly connected to the outer peripheral walls at both ends of the sliding bushing.

[0009] A further improvement is that a set of spring connecting rods are symmetrically arranged on the side of the bottom of the hinge seat facing the clamping plate, a spring groove is provided on the upper surface of the fixing bolt near the right-angle end, the two ends of the second return spring are respectively connected to the two spring connecting rods, and the middle part of the second return spring is located on the spring groove.

[0010] A further improvement is that a fixing bolt pivot is fixedly connected to both sides of the middle of the long side of the fixing bolt, and the fixing bolt is hinged to the hinge seat through the fixing bolt pivot.

[0011] A further improvement is that a set of pressure sleeve through holes are symmetrically opened on both sides of the sliding bushing at one end of the frame near the clamping plate.

[0012] A further improvement is that: a first clamping rod through hole is provided at the middle of the pressure sleeve through hole of the clamping plate, the diameter of the first clamping rod through hole is smaller than the diameter of the pressure sleeve through hole, and a second clamping rod through hole is provided at the end of the frame away from the clamping plate corresponding to the first clamping rod through hole.

[0013] A further improvement is that stacking docking slots are provided through the four corners of the frame, and stacking docking plugs are inserted into the stacking docking slots. The two ends of the stacking docking plugs are respectively inserted into the stacking docking slots of the adjacent upper and lower frames to facilitate the stacking of the clamp frames.

[0014] Compared with existing technologies, the above technical solution has the following advantages:

[0015] By using a pressure-holding assembly in conjunction with a pressure-holding locking assembly, and through the one-way conical steps of the pressure-holding top rod forming a one-way groove that engages with the locking block of the fixing bolt, it is possible to ensure that the pressure-holding top rod does not spring back during one-way movement. Even when the pressure block is removed, the pressure-holding top rod can still hold the clamping plate, ensuring the clamping and pressure holding of the pencil board. The pressure holding operation of the pencil board can be performed without the need for continuous pressure from a hydraulic cylinder, saving space in the clamping frame. The clamping frame can be moved during pressure holding for convenient subsequent operations. The overall structure is simple, the operation is convenient and quick, and production efficiency is improved. Attached Figure Description

[0051] The working principle of this utility model:

[0052] When the pressure holding is not in use and the pencil board is not clamped, the pressure holding push rod of the pressure holding assembly is far away from the clamping plate, and the locking block of the pressure holding locking assembly is not engaged in the one-way slot of the pressure holding push rod;

[0053] During clamping and pressure holding, the clamping frame is placed on the worktable and initially limited by the frame limiting baffle and frame limiting block. Then, the frame fixing cylinder of the frame fixing assembly moves the frame fixing pressure block forward to limit and clamp the frame. Next, the pencil plate is placed between the two guide rods, the clamping plate, and the end of the frame furthest from the pressure holding assembly. Then, the hydraulic cylinder of the pressurizing assembly moves the pressure block towards the frame, and the pressure sleeve at the front end of the pressure block moves accordingly, passing through the pressure sleeve through the frame to move the clamping plate towards the pencil plate for initial clamping. The forward movement of the pressure block causes the release support block and release block to move (the release cylinder has a neutral solenoid valve that allows the cylinder rod to move even when not in operation). As the pressure block moves, it pushes the pressure holding top rod of the pressure holding assembly towards the clamping plate. Once in position, the pressure holding begins. The locking bolt of the locking assembly, through the action of the second spring, engages with the corresponding one-way slot of the pressure-holding top rod. The hydraulic cylinder then retracts, moving the pressure block and pressure sleeve away from the frame to stop pressurization. The one-way slot formed between the one-way conical steps, combined with the locking bolt's engagement, ensures that the pressure-holding top rod moves unidirectionally without rebounding. Even when the pressure block leaves, the pressure-holding top rod remains pressed against the clamping plate, ensuring the pencil board is clamped and pressurized. This eliminates the need for continuous pressure from the hydraulic cylinder, saving space in the clamping frame. The clamping frame can be moved during pressure holding for easier subsequent operations. Afterward, the clamping of the frame is released, the frame position is moved, and the above operation is repeated to clamp and pressurize pencil boards in other positions within the frame. Finally, the clamping frame is removed and placed in another location for pressure holding.

[0054] When it is necessary to release the pressure and remove the clamp after the pressure holding is completed, place the clamp frame that needs to be released back on the worktable, and then clamp and limit the frame. The clamping cylinders of the first and second plate removal clamping components drive the corresponding clamping rods through the frame and clamping plate to clamp the pencil board. This ensures that the pencil board will not move after subsequent pressure release, making it convenient to pick up and transport the pencil board. Then, the pressure release cylinder of the pressure release component drives the pressure release support block and pressure release block to move towards the pressure holding top rod. The tapered through groove of the pressure release block cooperates with the inclined surface of the long side of the fixing bolt to press down on the long side end of the fixing bolt. The short side of the fixing bolt will move away from the slot of the pressure holding top rod, releasing the locking of the pressure holding top rod. At this time, the setting of the first return spring will make the pressure holding top rod move away from the clamping plate, releasing the pressure holding clamp on the pencil board. Then the pencil board can be removed.
