Technical Field

[0001] The invention relates to the technical field of plastic product clamping and feeding, in particular to a plastic product clamping and feeding combined device. Background Art

[0002] The gripper combined feeding device for plastic products is usually used in automated production lines to transport plastic products or raw materials from one place to another. This device combines a gripper mechanism and a feeding system to improve production efficiency and reduce the need for manual operation. The gripper part is generally a robotic arm or gripping device that can clamp or hold the plastic product. The gripper can be pneumatic, hydraulic or electric driven, and the common working method is to fix the material with two clamps or claws for movement or transportation.

[0003] When the existing plastic product clamping and grabbing combined feeding device grabs plastic products for labeling, if there is dust at the labeling position, it may affect the adhesion of the label, causing label position deviation or label quality problems. The existing device may not be able to remove these impurities in a timely and effective manner, affecting the appearance and quality of the final product.

[0004] In summary, the prior art lacks a technology for cleaning the labeling position while labeling and loading plastic products. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the background technology and to propose a clamping and grasping combined feeding device for plastic products.

[0006] In order to achieve the above purpose, the technical solution adopted by the present invention is: a clamping and grabbing combined feeding device for plastic products, including a processing table, a conveying frame is fixedly connected to the processing table, a rotating frame is rotatably connected to the processing table, a mobile frame is provided on one side of the rotating frame, a clamping mechanism is fixedly connected to the mobile frame, an adjusting frame is slidably provided on one side of the mobile frame, a dust sticking mechanism is rotatably connected to the adjusting frame, a pressing frame is slidably provided on the adjusting frame, and a transmission mechanism is rotatably connected to the adjusting frame.

[0007] Preferably, a motor is fixedly connected to the bottom end of the rotating frame, the motor is fixedly connected to the processing table, an arc-shaped toothed disc is rotatably connected to the rotating frame, and the arc-shaped toothed disc is fixedly connected to the processing table.

[0008] Preferably, an electric push rod is connected and fixedly arranged on the movable frame, and the other end of the electric push rod is connected and fixedly arranged on the rotating frame.

[0009] Preferably, the grabbing mechanism includes a hydraulic rod, which is fixedly connected to the movable frame, a hinge seat is fixedly connected to the hydraulic rod, connecting rods are rotatably connected to both ends of the hinge seat, a slider is rotatably connected to the other end of the connecting rod, the slider is slidably matched with the movable frame, and a grabbing plate is fixedly connected to the bottom end of the slider.

[0010] Preferably, a spring is fixedly provided at one end of the adjustment frame, and the other end of the spring is fixedly provided at the movable frame, and inclined rods are fixedly provided at both ends of the upper side of the adjustment frame, and the outer wall of the inclined rod is provided in sliding contact with the outer wall of the slider, and two top rods are rotatably provided on the adjustment frame.

[0011] Preferably, the dust sticking mechanism includes two rotating shafts, which are rotatably connected to the adjusting frame, and a belt is frictionally transmitted between the bottom ends of the two rotating shafts. A tape roll is slidingly fitted on the outer wall of one of the rotating shafts, and the tape on the tape roll is movably in contact with the top rod, and a worm gear is fixedly connected to the other rotating shaft.

[0012] Preferably, a toggle rod is slidably provided on the inner wall of the pressing frame, a universal joint A is fixedly connected to the toggle rod, a sleeve rod is fixedly connected to the other end of the universal joint A, a rotating sleeve is slidably provided on the sleeve rod, the rotating sleeve is rotatably connected to the moving frame, a transmission wheel is fixedly connected to one end of the rotating sleeve, the transmission wheel is meshed with an arc-shaped gear disk for transmission, and the pressing frame is in sliding contact with the tape on the tape roll.

[0015] Compared with the prior art, the present invention has the following beneficial effects: By setting up a dust sticking mechanism, when the plastic product is grabbed by the card grab plate, the tape on the tape roll will be attached to the position of the plastic product to be labeled. The tape has strong adhesion and can quickly and effectively remove dust and impurities in the label area, thereby ensuring the adhesion effect of the label and avoiding label deviation, bubbling or falling off. The combination of the dust sticking mechanism and the card grab plate automates the cleaning action and reduces the need for manual intervention, which not only improves production efficiency but also reduces labor intensity.

[0016] By setting up a pressing frame, after the tape is attached to the position of the plastic product to be labeled, the pressing frame can be moved back and forth under the drive of the toggle rod to flatten the tape, so that the tape can be in closer contact with the surface of the plastic product, increasing the tape's adsorption force on dust and impurities, further enhancing the tape's cleaning effect, effectively improving the dust cleaning efficiency, ensuring the cleanliness of the label area and the label adhesion quality, and at the same time improving the efficiency and stability of the automated production line.

[0017] By setting up a transmission mechanism, after the adjusting frame is moved away and the tape is torn off, the transmission mechanism can automatically drive the rotating shaft to rotate, and the tape can be automatically reeled after being torn off, and a new tape portion can be pulled out for the next cleaning operation, which greatly improves the automation level of the production line and improves production efficiency, while reducing manual intervention and operating errors, ensuring the effective use of the tape, avoiding waste, and improving the cleaning effect.
