Description

Technical Field

[0001] This utility model relates to the field of self-adhesive label technology, and in particular to a waste discharge device for self-adhesive labels. Background Technology

[0002] Self-adhesive labels typically consist of three parts: the face stock, the adhesive, and the backing paper. During production, the labels undergo a die-cutting process to achieve their final shape and size. This process not only determines the label's appearance but also directly affects its performance and subsequent processing efficiency. However, the die-cutting process generates a large amount of waste in addition to the finished labels. This waste usually exists in large pieces, such as the gaps between labels and the unused edges of the labels. These wastes are often continuous strips or whole sheets and need to be cleaned up promptly to avoid affecting subsequent production.

[0003] In existing technologies, waste materials are usually in the form of large pieces or strips, which are bulky and difficult to stack or recycle effectively, occupying a lot of storage space, increasing warehousing costs and management difficulties. Moreover, when the waste materials are crushed and recycled, the large pieces of waste materials go directly into the crushing equipment, which will put a large load on the crushing blades and motors, which can easily lead to accelerated wear of the equipment and even cause failure. Therefore, a self-adhesive label waste discharge device is proposed to solve the above-mentioned problems. Utility Model Content

[0004] In order to address the technical problems in the prior art, where waste materials are usually in large pieces or strips, which are bulky and difficult to effectively stack or recycle, and where large pieces of waste material directly enter the crushing equipment during crushing and recycling, which would put a large load on the crushing blades and motor, this application provides a self-adhesive label waste discharge device.

[0005] The present invention discloses a waste removal device for self-adhesive labels, including a die-cutting machine body. A waste removal mechanism is provided on the upper surface of the die-cutting machine body. The waste removal mechanism includes a scraper block, and the movement of the scraper block pushes the label waste material to move.

[0006] The upper surface of the die-cutting machine body is provided with a processing mechanism, which includes a shredder. The rotation of the shredder shreds the label waste.

[0007] Preferably, the waste discharge mechanism further includes waste discharge troughs, with two waste discharge troughs respectively opened on the upper surface of the frame of the die-cutting machine body and located on both sides of the moving platform of the die-cutting machine body.

[0008] With the above technical solution, a waste discharge trough is provided on the die-cutting machine body and located on both sides of the moving platform. Since the width of the moving platform is only slightly wider than or equal to the width required for die-cutting the self-adhesive label, the die-cut label waste will naturally fall into the waste discharge trough by its own gravity for subsequent processing.

[0009] Preferably, a movable electric push rod is fixedly installed in the frame groove of the die-cutting machine body, one end of the telescopic rod of the movable electric push rod is fixedly installed on the right side of the scraper, and the scraper is slidably connected to the inner wall of the limiting groove of the waste discharge trough.

[0010] The above technical solution involves fixing the die-cutting machine body to a movable electric push rod. The push rod's telescopic arm is then fixed to the scraper block. The extension and retraction of the telescopic arm moves the scraper block within the waste discharge trough. The scraper block's sliding connection to the waste discharge trough ensures stable movement, thus propelling label waste within the trough. The scraper block can be made of 45# steel, which, after surface quenching, has high hardness and good wear resistance, suitable for long-term, high-frequency reciprocating motion, extending its service life. The movable electric push rod can be a LAN series electric push rod, equipped with a controller and position sensor for precise control. This series of electric push rods can meet the needs of small and medium-sized die-cutting machines; specific selection can be made according to actual conditions.

[0011] Preferably, a guide frame is fixedly installed on the upper left side of the frame of the die-cutting machine body, and a lifting electric push rod is fixedly installed on the upper top surface of the guide frame. A row of blades is fixedly installed at one end of the telescopic rod of the lifting electric push rod, and the row of blades is slidably connected to the inner wall of the limiting groove of the guide frame.

[0012] Through the above technical solution, the die-cutting machine body is fixedly installed with the guide frame. The guide platform of the guide frame is set at an angle so that the waste labels slide into the processing frame. The material of the guide frame can be carbon steel, which has high strength and good toughness and can withstand the weight and vibration of the lifting electric push rod and the blade. The guide frame is fixedly installed with the lifting electric push rod. The model of the lifting electric push rod can be the same as the moving electric push rod. The blade is fixedly installed on the telescopic rod of the lifting electric push rod. The extension and retraction of the telescopic rod can drive the blade to rise and fall. The blade is slidably connected to the guide frame to ensure the stability of its rise and fall, thereby cutting the waste labels before entering the processing frame, reducing their size, thereby reducing the load on the crushing blade, improving the crushing efficiency, and extending the service life of the crushing blade. The material of the blade can be high-speed steel, which has high hardness and strong wear resistance, and is suitable for cutting waste materials.

[0013] Preferably, the processing mechanism further includes a processing frame with a discharge port, the processing frame being fixedly installed on the upper left side of the support plate of the die-cutting machine body, a motor being fixedly installed on the front end surface of the processing frame, and the output shaft of the motor being rotatably connected to the inner wall of the front end groove of the processing frame through a bearing.

[0014] Through the above technical solution, the processing frame is fixedly installed to the die-cutting machine body, and the motor is also fixedly installed to the processing frame. The output shaft of the motor is rotatably connected to the processing frame through bearings to ensure the stability of the motor output shaft rotation. The motor model can be a three-phase asynchronous motor, which is suitable for driving the pulverizing blade to rotate, meeting the needs of small and medium-sized pulverizing mechanisms. It is equipped with a frequency converter and encoder to achieve precise control. A temperature sensor can be equipped as needed to monitor the motor operating temperature and prevent overheating damage. The processing frame can be made of stainless steel, which is corrosion-resistant, high-strength, and can withstand the vibration and impact generated during the pulverizing process.

[0015] Preferably, the output shaft of the motor is fixedly mounted with a rotating rod, and the rotating rod is rotatably connected to the inner wall of the groove of the processing frame through a bearing.

[0016] The above technical solution involves fixing the motor output shaft to the rotating rod, driving the rotating rod to rotate. The rotating rod is rotatably connected to the processing frame through bearings, ensuring the stability of the rotating rod's rotation. The rotating rod can be made of 40Cr alloy steel, which has high strength and good toughness, is suitable for transmitting the motor's power, and is not easily deformed or broken.

[0017] Preferably, the pulverizing blade is rotatably connected to the inner sidewall of the processing frame via a bearing, and the rotating rod drives the pulverizing blade to rotate via a bevel gear set.

[0018] Through the above technical solution, the crushing blade is rotatably connected to the processing frame via bearings, ensuring the stability of the crushing blade's rotation. The rotating rod drives the crushing blade to rotate through a bevel gear set. The high-speed rotation crushes the waste into small particles, facilitating subsequent recycling and reducing storage and transportation costs. The inner bottom wall of the processing frame is also designed with an inclination, allowing the crushed waste to slide down the inlet through the inclination to enter the subsequent collection device. The crushing blade can be made of tungsten steel, which has extremely high hardness and wear resistance, making it suitable for high-speed rotation crushing of waste and providing a long service life.

[0019] The beneficial effects of this utility model are as follows: 1. By setting up a waste discharge mechanism, the label waste is moved. The extension and retraction of the electric push rod can drive the scraper to move in the waste discharge trough, thereby pushing the label waste in the waste discharge trough. The guide platform of the guide frame is set at an inclination so that the waste labels can slide into the processing frame. The extension and retraction of the electric push rod can drive the blade to rise and fall, thereby cutting the label waste before entering the processing frame, reducing its size, thereby reducing the load on the crushing blade, improving crushing efficiency, and extending the service life of the crushing blade. This solves the technical problem in the existing technology that when crushing and recycling waste, large pieces of waste directly enter the crushing equipment, which will put a large load on the crushing blades and motor, easily leading to accelerated wear of the equipment and even causing failure.

[0020] 2. By setting up a processing mechanism, the label waste is crushed. The motor drives the rotating rod to rotate, and the rotating rod drives the crushing blade to rotate through the bevel gear set. The high-speed rotation crushes the waste into small particles, which facilitates the subsequent recycling of the waste and reduces storage and transportation costs. The inner bottom wall of the processing frame is also designed with an inclination. The crushed waste slides down the inclination bottom wall to the discharge port and enters the subsequent collection device. This solves the technical problem in the existing technology that the waste is usually in large pieces or strips, which are bulky and difficult to stack or recycle effectively, occupying a lot of storage space and increasing storage costs and management difficulty.

[0025] In order for the waste label material after die-cutting to fall naturally into the waste discharge trough 2 under its own weight, the waste discharge mechanism also includes waste discharge trough 2. Two waste discharge troughs 2 are respectively opened on the upper surface of the frame of the die-cutting machine body 1 and located on both sides of the moving platform of the die-cutting machine body 1. Since the width of the moving platform is only slightly wider than or equal to the width required for die-cutting the self-adhesive label, the waste label material after die-cutting will fall naturally into the waste discharge trough 2 under its own weight for subsequent processing.

[0026] To ensure the stability of the scraper block 31's movement, a movable electric push rod 3 is fixedly installed in the frame groove of the die-cutting machine body 1.

The slidable connection between the scraper block 31 and the waste discharge trough 2 ensures the stability of the scraper block 31's movement, thereby pushing the label waste material to move in the waste discharge trough 2. The scraper block 31 can be made of 45# steel, which has high hardness and good wear resistance after surface quenching treatment, making it suitable for long-term high-frequency reciprocating motion and extending its service life. The movable electric push rod 3 can be a LAN series electric push rod, equipped with a controller and a position sensor to achieve precise control. This series of electric push rods can meet the needs of small and medium-sized die-cutting machines, and the specific model can be selected according to the actual situation.

The blade 42 is slidably connected to the guide frame 4 to ensure the stability of its rise and fall, thereby cutting the label waste before entering the processing frame 5, reducing its size, thereby reducing the load on the crushing blade 7, improving the crushing efficiency, and extending the service life of the crushing blade 7. The blade 42 can be made of high-speed steel, which has high hardness and strong wear resistance, and is suitable for cutting waste.

[0028] By setting up a waste discharge mechanism, the label waste is pushed to move. The extension and retraction of the telescopic rod of the moving electric push rod 3 can drive the scraper 31 to move in the waste discharge trough 2, thereby pushing the label waste in the waste discharge trough 2.

This solves the technical problem in the prior art that when crushing and recycling waste, large pieces of waste directly enter the crushing equipment, which will cause a large load on the crushing blade 7 and the motor 51, easily leading to accelerated wear of the equipment and even causing failure.

[0029] In order to crush the label waste, a processing mechanism is provided on the upper surface of the die-cutting machine body 1. The processing mechanism includes a crushing blade 7, and the rotation of the crushing blade 7 crushes the label waste.

It is equipped with a frequency converter and encoder to achieve precise control. A temperature sensor can be equipped as needed to monitor the operating temperature of motor 51 to prevent overheating damage. The processing frame 5 can be made of stainless steel, which is corrosion-resistant, high-strength, and can withstand the vibration and impact generated during the pulverizing process.

[0031] To drive the rotating rod 6 to rotate, the output shaft of the motor 51 is fixedly mounted with the rotating rod 6.

The material of the rotating rod 6 can be 40Cr alloy steel, which has high strength and good toughness, is suitable for transmitting the power of the motor 51, and is not easy to deform or break.

[0032] To crush waste into small particles, the crushing blade 7 is rotatably connected to the inner wall of the processing frame 5 via bearings.

The high-speed rotation crushes the waste into small particles, which facilitates the subsequent recycling of the waste and reduces storage and transportation costs. The inner bottom wall of the processing frame 5 is also designed with an inclination. The crushed waste slides down the inclination bottom wall to the discharge port and enters the subsequent collection device. This solves the technical problem in the prior art that the waste is usually in large pieces or strips, which are bulky and difficult to stack or recycle effectively, occupying a lot of storage space and increasing storage costs and management difficulty.

[0034] Working principle: When the die-cutting machine body 1 is die-cutting the label, the waste material falls into the waste discharge trough 2 due to its own gravity. The PLC controls the start of the moving electric push rod 3 through the preset program. Its telescopic rod pushes the scraper 31 to move in the waste discharge trough 2, thereby moving the waste material in the waste discharge trough 2. When it moves to below the rack 42, the PLC starts the lifting electric push rod 41 to drive the rack 42 to descend and cut the waste material. The lifting height of the rack 42 is monitored in real time by the pressure sensor to avoid overload. The pressure sensor detects the contact pressure between the rack 42 and the waste material. When it exceeds the set value, the PLC immediately stops the rack 42 and issues an alarm. The cut waste material slides down to the processing frame 5 through the waste discharge trough 2. When waste needs to be crushed, the PLC starts the motor 51, which drives the rotating rod 6 to rotate. The rotating rod 6 drives the crushing blade 7 to rotate at high speed through the bevel gear set. The speed of the crushing blade 7 is adjusted by the frequency converter to ensure that the waste is crushed evenly. The vibration sensor monitors the vibration amplitude of the crushing blade 7. When it exceeds the set value, the PLC reduces the speed or stops the equipment. The crushed waste slides down the inclined bottom wall of the processing frame 5 to the discharge port. When the waste enters the collection device through the discharge port, the PLC records the amount of waste collected through the weight sensor. When the collection device is full, the PLC issues an alarm to prompt the operator to replace the collection device. Before each shift, apply lithium-based grease to the guide rail of the telescopic rod of the mobile electric push rod 3. Add grease to the guide rail and sliding bearing of the telescopic rod of the lifting electric push rod 41 weekly. Add high-temperature grease to the bearing of the crusher blade 7 monthly through the oil cup. Apply gear grease to the bevel gear set quarterly. After each lubrication, the operator must record the lubrication location, lubricant type and lubrication time on the HMI interface. Check the wear of scraper 31 and blade 42 weekly. If the wear exceeds 0.5mm, they need to be replaced. Check the pulverizer blade 7 monthly to see if it is intact. If cracks or wear are found, it needs to be replaced immediately. Check the sensitivity of the sensor quarterly to ensure that the signal is normal. After each maintenance, the operator must record the maintenance content, replaced parts and maintenance time on the HMI interface for easy traceability.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
