Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging bag sealing, and more particularly to heat sealing equipment for veterinary drug packaging bags. Background Technology
[0002] Veterinary drug packaging bag sealing equipment is mainly used for efficient and precise sealing of veterinary drug packaging bags, ensuring the airtightness of the medicine and preventing moisture, leakage, or contamination. This equipment uses an ultrasonic thickness sensor to detect the thickness of the packaging bag in real time and intelligently adjusts the sealing temperature to ensure a firm seal and adaptability to different materials. An elastic pressure roller prevents the veterinary drug from being squeezed out during sealing, and a heating strip provides uniform heat sealing, ensuring a smooth seal. The overall structure is stable and easy to operate, suitable for veterinary drug production and packaging processes, improving packaging efficiency and quality, and ensuring drug safety and storage stability.
[0003] While existing technologies can achieve a certain sealing effect on veterinary drug packaging bags, they have drawbacks: they cannot effectively prevent veterinary drugs from spilling out during sealing, affecting the normal packaging process, and they lack thickness detection and appropriate temperature control functions. In view of this, we have proposed a heat-sealing device for veterinary drug packaging bags, which solves the above problems. Utility Model Content
[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a heat-sealing device for veterinary drug packaging bags.
[0005] The technical solution of this utility model: a heat sealing device for veterinary drug packaging bags, including a machine body, a rotating seat, a first roller, a second roller, and an ultrasonic thickness sensor. The rotating seat is rotatably mounted on the upper end of the machine body, and a limiting strip with an elastic mechanism is mounted on the lower end of the rotating seat. A heating strip is provided on the upper end of the machine body. A fixed frame is fixed on one side of the machine body. The first roller is rotatably mounted between the fixed frames. A lifting block with an elastic mechanism is inserted into the upper end of the fixed frame. The second roller is rotatably mounted between the lifting blocks. An ultrasonic thickness sensor is fixed to the lower end of the middle part of the second roller.
[0006] When using this device, insert one end of the veterinary drug bag to be sealed between roller one and roller two, and then manually pull it out from the other end of roller one and roller two. Under the downward pressure of roller two, the veterinary drug will not pass through the gap between roller one and roller two, while the bag opening will still move forward. During the movement of the packaging bag on the surface of roller one and roller two, the thickness of the packaging bag can be measured by an ultrasonic thickness sensor. The appropriate sealing temperature can be adjusted by the controller. After the bag opening moves to the top of the heating strip, manually pressing down the rotating seat will achieve the sealing effect of the bag opening. This device can prevent the veterinary drug from being squeezed out of the bag opening when there is an air vent and has a temperature adjustment function adapted to the thickness of the packaging bag, achieving a good, convenient, stable and reliable sealing effect for veterinary drug packaging bags, and has high practicality.
[0007] Preferably, a base is fixed to the lower end of the machine body, and a knob is provided on the outer wall of one side of the machine body. The base enhances the overall stability and prevents the equipment from shaking during operation. The knob can be used to adjust the equipment parameters and improve applicability.
[0008] Preferably, a controller is fixed to one side of the outer wall of the machine body. The controller is for electrically heating the heating strip and adjusting the temperature of the heating strip. The controller automatically adjusts the heating temperature according to the thickness of the packaging bag to avoid poor sealing or material burn due to improper temperature. The integrated control panel makes it easy for users to set parameters and improves the convenience of use.
[0009] Preferably, a mounting column is fixed inside the second roller, and the mounting column is fixed on the opposite side of the lifting block. A bearing is fixed on the outer wall of the mounting column, and the second roller is rotatably mounted on the outer wall of the bearing. An ultrasonic thickness sensor is fixed at the lower middle part of the mounting column. The ultrasonic sensor is directly fixed to the mounting column to ensure stable measurement position and improve thickness detection accuracy. The bearing structure makes the second roller rotate smoothly and avoids jamming or wear of the packaging bag during transportation. The principle of the ultrasonic thickness sensor is as follows: the sensor probe directly contacts the surface of the packaging bag without damaging the material. It measures the thickness by emitting ultrasonic waves and receiving the echo reflected from the other side of the material, and calculating the sound wave propagation time difference.
[0010] Preferably, a limit pin is inserted into the lower end of the lifting block, the limit pin passes through the fixed frame, and a linear spring is fixedly installed at the cap of the limit pin and the lower end of the fixed frame. The linear spring provides adjustable pressure, so that the roller can adapt to packaging bags of different thicknesses and ensure stable contact. The design of the limit pin + linear spring simplifies assembly and facilitates maintenance and adjustment.
[0011] Preferably, a linear spring is fixed between the limiting strip and the rotating seat. The linear spring provides cushioning when the rotating seat is pressed to avoid instantaneous impact damage to the packaging bag or equipment. After sealing, the linear spring pushes the limiting strip back to its original position, improving operating efficiency. The structure of the linear spring ensures uniform downward pressure on the rotating seat, preventing skewed sealing or partial unsealing.
[0012] Preferably, a mounting bracket is fixed to one side of the upper end of the machine body, and the rotating seat is rotatably mounted between the mounting brackets. A torsion spring is fixed to one side of the outer wall of the mounting bracket. The rotating end of the torsion spring is fixedly connected to the rotation center of the rotating seat. The torsion spring ensures that the rotating seat automatically springs up after sealing, reducing manual intervention. The torsion force of the torsion spring is limited, so the rotating seat will only rise about 45 degrees before coming to a stop.
[0013] Compared with existing technologies, the advantages of this utility model are:
[0014] I. This utility model uses an ultrasonic thickness sensor to detect the thickness of the packaging bag in real time, and combines it with an intelligent temperature control system to automatically adjust the sealing temperature, ensuring a firm seal and adapting to different materials.
[0015] Second, based on the first beneficial effect, the roller elastic pressing mechanism prevents veterinary drug leakage and simplifies the preparation process before manual operation. At the same time, the spring structure of components such as the rotating seat and lifting block provides stable pressure, making the sealing process smooth and efficient.
[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0030] When using this device, the end of the veterinary drug bag to be sealed can be inserted between roller 12 and roller 23.

The controller 8 automatically adjusts the heating temperature according to the thickness of the packaging bag to avoid poor sealing or material burn due to improper temperature. The integrated control panel makes it easy for users to set parameters and improves the convenience of use.
[0034] Inside the roller 13, there is a fixed mounting column 11. The mounting column 11 is fixed on the opposite side of the lifting block 2.
