Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and in particular to an adjustable clamp for printing on glass bottles. Background Technology

[0002] During the production process, glass bottles are usually printed with some logos according to commercial needs. In order to ensure the printing quality, the printing equipment needs to use clamps to stably hold the glass bottles on the printing station.

[0003] Existing glass bottle printing fixtures generally include two clamping blocks that can be held or separated. They are clamped from both sides of the glass bottle by a drive device. After printing is completed, the glass bottle is released and then the accompanying robotic arm removes the glass bottle for subsequent work.

[0004] Existing glass bottle printing fixtures often only support single-sided printing on cylindrical bottles during the production process. When multi-sided printing is required on irregularly shaped glass bottles such as oval, square, and conical bottles, the fixture usually needs to be released and the bottle rotated. However, once the fixture is released, the bottle's position is lost, and it is easy for the position to shift or even tip over during rotation. This can lead to misalignment and other defects in subsequent printing work on other sides, making it difficult to perform effectively. Utility Model Content

[0005] In order to overcome the problem that the glass bottle position is easily shifted when changing sides during the multi-sided printing process of glass bottles in the existing technology, which affects the multi-sided printing work, this utility model provides an adjustable clamp for glass bottle printing.

[0006] The technical problem to be solved by this utility model can be achieved through the following technical solution: An adjustable fixture for printing on glass bottles includes a frame and a drive lifting mechanism, the drive lifting mechanism being mounted on the top of the frame, and also includes a vertical limiting mechanism, a horizontal clamping mechanism and a surface turning mechanism. The driving end of the lifting mechanism is connected to the vertical limiting mechanism. The lifting mechanism is used to drive the vertical limiting mechanism to longitudinally press the glass bottle. The horizontal clamping mechanism is connected to the vertical limiting mechanism. The horizontal clamping mechanism is slidably mounted on the frame. The horizontal clamping mechanism clamps the glass bottle laterally. The vertical limiting mechanism includes an elastic pressing member for contacting the mouth of the glass bottle.

[0007] Preferably, the vertical limiting mechanism further includes a cross lifting rod, which includes a vertical lifting rod and a horizontal lifting rod. The vertical lifting rod and the horizontal lifting rod are fixedly connected. The upper end of the vertical lifting rod is connected to the driving end of the driving lifting mechanism. The elastic pressing member is disposed at the lower end of the vertical lifting rod.

[0008] Preferably, the vertical lifting rod and the horizontal lifting rod are an integrated steel structure.

[0009] Preferably, the elastic pressing member includes a limiting ball and a telescopic spring. The limiting ball is used to abut against the mouth of the glass bottle. The vertical lifting rod slides through the limiting ball, and the telescopic spring is connected between the limiting ball and the horizontal lifting rod.

[0010] Preferably, the horizontal clamping mechanism includes a slide rail, a connecting rod, and a V-shaped limiting block. Two sets of connecting rods are provided and are movably connected to both ends of the horizontal lifting rod, respectively. Two sets of slide rails are provided and are fixedly mounted on the frame. Two sets of V-shaped limiting blocks are provided and are slidably connected to the corresponding slide rails, respectively. The upper ends of the two sets of V-shaped limiting blocks are rotatably connected to the ends of the corresponding connecting rods.

[0011] Preferably, the surface of the limiting ball is a smooth surface.

[0012] Preferably, reset plates corresponding to the V-shaped limit blocks are fixedly installed on both sides of the frame, and a compressible reset spring is connected between each set of reset plates and the corresponding V-shaped limit block.

[0013] Preferably, the rotating mechanism includes a servo motor and a rotating disk. The servo motor is fixedly mounted on the frame, and the rotating disk is rotatably mounted between two sets of V-shaped limit blocks. The upper surface of the rotating disk is lower than the bottom surface of the V-shaped limit blocks, and the rotating disk is fixedly connected to the spindle of the servo motor.

[0014] Preferably, a rubber pad is installed on the clamping surface of each set of V-shaped limiting blocks.

[0015] Preferably, the upper surface of the rotating disk is provided with an anti-slip pad.

[0016] The beneficial effects of this utility model are: 1. This utility model uses a V-shaped limiting block and a limiting ball to achieve horizontal and vertical limiting clamping of the glass bottle, which facilitates stable printing. By releasing the V-shaped limiting block, the servo motor of the rotating mechanism drives the rotating disk to rotate at a certain angle, while the limiting ball maintains vertical limiting during this process. This facilitates the smooth rotation and reversal of the glass bottle, and then printing can be performed on the flipped side of the glass bottle. Through the adjustment and coordination of the releasing and clamping action of the V-shaped limiting block, as well as the coordination of the rotating disk and the vertical limiting ball, multi-sided printing can be easily completed.

[0017] 2. This utility model features an elastic pressing component that longitudinally limits the glass bottle. A vertical lifting rod passes through a limiting ball, allowing them to slide relative to each other. When the driving lifting mechanism lowers the cross lifting rod, the limiting ball stops at the bottle opening, and the telescopic spring is compressed. When the driving lifting mechanism raises the cross lifting rod, the spring's rebound force is released to a certain extent, ensuring the limiting ball remains in contact with the bottle opening within a certain range. During printing and surface turning, the glass bottle is longitudinally limited, preventing pattern stretching, deformation, or misalignment caused by bottle displacement, which would affect the quality of the printed pattern and improve printing accuracy and consistency.

[0019] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0020] like Figures 1-6As shown, an adjustable clamp for printing on glass bottles is used to clamp and position glass bottles 1 that require multi-sided printing, such as square glass bottles 1. The clamp includes a frame 2, a drive lifting mechanism 3, a vertical limiting mechanism, a horizontal clamping mechanism, and a turning mechanism. The drive lifting mechanism 3 is provided on the top of the frame 2. The drive lifting mechanism 3 can be an electric telescopic rod. The drive end of the drive lifting mechanism 3 is connected to the vertical limiting mechanism. The drive lifting mechanism 3 is used to drive the vertical limiting mechanism to longitudinally press the glass bottle 1. The horizontal clamping mechanism is connected to the vertical limiting mechanism and the horizontal... The clamping mechanism is slidably mounted on the frame 2. The horizontal clamping mechanism clamps the glass bottle 1 horizontally. The driving lifting mechanism 3 can drive the adjustment of the clamping positions of the vertical limiting mechanism and the horizontal clamping mechanism. The vertical limiting mechanism includes an elastic pressing member for contacting the mouth of the glass bottle 1. When one side of the glass bottle 1 is printed, the driving lifting mechanism 3 drives the vertical limiting mechanism to move upward, but the elastic pressing member still contacts and cooperates with the glass bottle 1 by relying on the rebound force. At the same time, the horizontal clamping mechanism releases the glass bottle 1, and the turning mechanism drives the glass bottle 1 to rotate, so that the glass bottle 1 turns to print the other side.

[0021] It should be noted that the print head of the printing assembly is located on one side of the frame 2 in the horizontal direction, and is horizontally aligned with the uncovered side of the glass bottle 1 that is clamped and positioned.

[0022] In some specific implementations, the vertical limiting mechanism also includes a cross lifting rod, which includes a vertical lifting rod 4 and a horizontal lifting rod 5. The vertical lifting rod 4 and the horizontal lifting rod 5 are perpendicular to each other and fixedly connected. The upper end of the vertical lifting rod 4 is connected to the driving end of the driving lifting mechanism 3, and the elastic pressing member is provided at the lower end of the vertical lifting rod 4.

[0023] Among them, the vertical lifting rod 4 and the horizontal lifting rod 5 are an integrated steel structure.

[0024] The elastic pressing component includes a limiting ball 7 and a telescopic spring 6. The limiting ball 7 is used to abut against the mouth of the glass bottle 1. Therefore, it is necessary to ensure that the diameter of the limiting ball 7 is larger than the mouth diameter of the glass bottle 1, so as to facilitate the longitudinal limiting of the glass bottle 1. The vertical lifting rod 4 passes through the limiting ball 7, and the two can slide relative to each other. The telescopic spring 6 is connected between the limiting ball 7 and the horizontal lifting rod 5, and the telescopic spring 6 is sleeved on the outside of the vertical lifting rod 4. When the driving lifting mechanism 3 drives the cross lifting rod to descend, the limiting ball 7 abuts against the mouth of the glass bottle 1 and stops. Then the telescopic spring 6 is pressed. When the driving lifting mechanism 3 drives the cross lifting rod to rise, the telescopic spring 6 releases the rebound force, which can keep the limiting ball 7 abutting against the mouth of the glass bottle 1 within a certain range.

[0025] In some specific implementations, the horizontal clamping mechanism includes a slide rail 10, a connecting rod 8, and a V-shaped limiting block 9. Two sets of connecting rods 8 are provided, each hinged to one end of the horizontal lifting rod 5. The two sets of connecting rods 8 are symmetrically distributed on both sides of the glass bottle 1. Two sets of slide rails 10 are fixedly mounted on the frame 2, symmetrically distributed on both sides of the glass bottle 1 and on the same plane as the bottom of the glass bottle 1. Two sets of V-shaped limiting blocks 9 are provided, symmetrically distributed on both sides of the glass bottle 1, and slidably connected to the corresponding slide rail 10. The upper ends of both sets of V-shaped limiting blocks 9 are hinged to the ends of the corresponding connecting rods 8. Rotary connection; the connecting rod 8 is in an inclined state, with its bottom end close to the glass bottle 1 and its top end away from the glass bottle 1. When the horizontal lifting rod 5 descends, it drives both sets of connecting rods 8 to rotate towards the glass bottle 1. The two sets of V-shaped limiting blocks 9 slide along the corresponding slide rails 10 towards the glass bottle 1 under the drive of the two sets of connecting rods 8, thus clamping the glass bottle 1. When the horizontal lifting rod 5 rises, it drives both sets of connecting rods 8 to rotate away from the glass bottle 1. The two sets of V-shaped limiting blocks 9 slide along the corresponding slide rails 10 away from the glass bottle 1 under the drive of the corresponding connecting rods 8, thus releasing the glass bottle 1. This allows the rotating mechanism to easily rotate the glass bottle 1 to change its surface for printing on different surfaces.

[0026] In some specific implementations, the surface of the limiting ball 7 is a smooth surface, which reduces the friction between the ball and the mouth of the glass bottle 1, thereby facilitating the rotation of the glass bottle 1 relative to the limiting ball 7.

[0027] In some specific implementations, reset plates 11 corresponding to V-shaped limit blocks 9 are fixedly installed on both sides of the frame 2. Reset springs 12 are fixedly installed on both sets of reset plates 11. One end of each set of reset springs 12 is fixedly connected to one side of the corresponding reset plate 11, and the other end is fixedly connected to one side of the corresponding V-shaped limit block 9. When the two sets of V-shaped limit blocks 9 slide along the corresponding slide rails 10 to clamp the glass bottle 1, the reset springs 12 are stretched to generate a rebound force. When the cross lifting rod rises, the two sets of reset springs 12 respectively pull the corresponding V-shaped limit blocks 9 away from the glass bottle 1, assisting the two sets of V-shaped limit blocks 9 to slide along the two sets of slide rails 10 away from the glass bottle 1, that is, to loosen the clamping of the glass bottle 1.

[0028] In some specific implementations, the rotating mechanism includes a servo motor 13 and a rotating disk 14. The servo motor 13 is fixedly mounted at the bottom of the frame 2, and the main shaft of the servo motor 13 is vertically upward. The rotating disk 14 is rotatably mounted between two sets of V-shaped limit blocks 9, and the upper surface of the rotating disk 14 is lower than the bottom surface of the V-shaped limit blocks 9. The rotating disk 14 is fixedly connected to the main shaft of the servo motor 13. When the printing on one side of the glass bottle 1 is completed, the horizontal clamping mechanism releases its clamping on the glass bottle 1, and the vertical lifting rod 4 moves upward. However, the limit ball 7 in the vertical limit mechanism still maintains its engagement with the glass bottle 1 to ensure that the glass bottle 1 does not shift during rotation. When the servo motor 13 is started, it drives the rotating disk 14 to rotate at a certain angle, causing the glass bottle 1 to rotate. At this time, the horizontal clamping mechanism continues to clamp the glass bottle 1, and then the printing work on the other side of the glass bottle 1 is carried out.

[0029] It should be noted that there are conveyor belts 15 on both sides of the frame 2. After the glass bottle 1 is transported to the frame 2 by the conveyor belt 15 on one side, it is placed on the rotating disk 14 by the matching mechanical gripper, and then clamped and positioned for printing. After the printing is completed, it is clamped and placed on the conveyor belt 15 on the other side by the mechanical gripper for continued transport.

[0030] In some other specific implementations, a rubber pad is installed on the clamping surface of each set of V-shaped limit blocks 9 to prevent damage to the glass bottle 1.

[0031] In some other specific embodiments, the upper surface of the rotating disk 14 is provided with an anti-slip pad to facilitate the stable placement of the glass bottle 1.

[0032] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution will now be briefly explained in conjunction with specific application scenarios: After the glass bottle 1 to be printed is conveyed to the frame 2 via the conveyor belt 15 on one side, it is placed on the rotating disk 14 by the matching mechanical gripper. The driving lifting mechanism 3 drives the vertical lifting rod 4 to descend, and the limiting ball 7 abuts against the bottle mouth of the glass bottle 1. The telescopic spring 6 is compressed and generates a rebound force, which makes it easy for the limiting ball 7 to press against the bottle mouth of the glass bottle 1, thus limiting the glass bottle 1 longitudinally. At this time, the driving lifting mechanism 3 continues to drive the vertical lifting rod 4. During this process, the vertical lifting rod 4 can slide relative to the limiting ball 7, and the vertical lifting rod 4 drives the horizontal lifting rod 5 to descend, and drives both sets of connecting rods 8 to rotate in the direction of the glass bottle 1. The two sets of V-shaped limiting blocks 9 slide along the corresponding slide rails 10 in the direction of the glass bottle 1 under the drive of the two sets of connecting rods 8, realizing the clamping of the glass bottle 1. At this time, the printing work is performed on one side of the glass bottle 1. When it is necessary to print on other sides of the glass bottle 1, the vertical lifting mechanism 3 continues to drive the vertical lifting rod 4 to descend. As the lowering lever 4 moves upward, the telescopic spring 6 releases its rebound force but still maintains a certain degree of compression. This ensures that the limiting ball 7 can still contact the mouth of the glass bottle 1 downward within a certain range, maintaining longitudinal limitation. At the same time, the horizontal lifting lever 5 rises, causing both sets of connecting rods 8 to rotate away from the glass bottle 1. The two sets of V-shaped limiting blocks 9 slide away from the glass bottle 1 along the corresponding slide rail 10 under the drive of the corresponding connecting rods 8, thus releasing the clamping of the glass bottle 1. When the servo motor 13 starts, it drives the rotating disk 14 to rotate at a certain angle, causing the glass bottle 1 to rotate. During this process, since the limiting ball 7 still maintains longitudinal pressure on the glass bottle 1, it is easy to rotate and change the surface smoothly. At this time, the driving lifting mechanism 3 drives the cross lifting lever to descend, continuing to clamp the glass bottle 1. Then, the printing work on different sides of the glass bottle 1 is carried out. After the printing is completed, it is picked up by the mechanical claw and placed on the conveyor belt 15 on the other side for continued transportation.

[0033] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
