Description

Technical Field

[0001] This utility model relates to the technical field of self-adhesive production equipment, specifically a feeding device for self-adhesive production. Background Technology

[0002] Self-adhesive labels, also known as pressure-sensitive labels, are composite materials made of paper, film, or other special materials as the face stock, coated with adhesive on the back, and with silicone-coated release paper as the backing paper. The adhesive raw materials of self-adhesive labels become viscous or even sticky at room temperature or low temperature, losing their fluidity and affecting their normal transportation and use. At the same time, it is necessary to detect material shortages in a timely manner during continuous production to avoid mechanical wear caused by equipment idling. Therefore, a feeding device for self-adhesive label production has been proposed. Utility Model Content

[0019] Example:

[0020] Please see Figure 1-3 The present invention provides the following technical solution: a feeding device for self-adhesive label production, comprising a feeding bucket 1 and a heating base 2;

[0021] A top cover 6 is installed on the top of the feeding barrel 1, a conveying pump 9 is installed on the top of the top cover 6, a conveying pipe is connected to the bottom of the conveying pump 9, and the conveying pipe extends to the bottom of the inner cavity of the feeding barrel 1; two upper and lower hoop rings 3 are fitted on the outside of the feeding barrel 1, and locking bolts are evenly distributed on the hoop rings 3.

[0022] A heating base 2 is installed at the bottom of the feeding hopper 1, and an upwardly protruding extension 5 is provided on the top of the heating base 2, which seals the bottom of the inner cavity of the feeding hopper 1.

[0023] A connecting rod 4 for fixing is welded between the hoop 3 and the heating base 2; a longitudinal mounting plate 7 is installed on the hoop 3, and liquid level sensors 8 are evenly distributed on the mounting plate 7. The liquid level sensors 8 are non-contact liquid level sensors.

[0024] A heating wire 10 is installed in the lower part of the inner cavity of the heating base 2, and a heat-conducting base plate 11 is installed at the top of the inner cavity of the heating base 2; the heating of the heating wire 10 keeps the gel-like raw material in the feeding bucket 1 active and prevents it from sticking.

[0025] The transfer pump 9 is linked with the liquid level sensor 8. When the liquid level is lower than the set lower limit, the transfer pump 9 stops pumping to prevent dry running.

[0026] A microcontroller (such as a microcontroller) is installed in the transfer pump 9 to read the signal from the liquid level sensor 8 and control the transfer pump 9 through programming;

[0027] A temperature sensor is installed in the inner cavity of the heating base 2 to monitor the temperature in real time. The heating base 2 is connected to a controller via a data cable. The controller is not shown in the figure at any position on the outer wall of the feeding hopper 1. The signal from the temperature sensor is fed back to the controller, and the controller adjusts the power of the heating wire 10 according to the set temperature range to achieve temperature control. An alarm horn is installed on the mounting plate 7, and the alarm horn is linked to the lowest liquid level sensor 8.

[0028] How this solution works:

[0029] The feeding hopper 1 is a container for storing self-adhesive raw materials. It is equipped with a top cover 6 to seal and prevent impurities from entering. Two upper and lower hoop rings 3 are fitted on the outside of the feeding hopper. The locking bolts on the hoop rings 3 can fasten the hoop rings 3 to the feeding hopper 1, thereby enhancing the stability of the feeding hopper 1 structure. At the same time, the hoop rings 3 are welded and fixed to the heating base 2 through the connecting rod 4, so as to realize the integrated installation of the heating base 2 and the hoop rings 3.

[0030] The heating base 2 is located at the bottom of the feeding hopper 1. Its top extension 5 protrudes upward and seals the bottom of the inner cavity of the feeding hopper 1 to prevent raw material leakage. A heating wire 10 is installed in the lower part of the inner cavity of the heating base 2, and a heat-conducting base plate 11 is installed on the top. When the heating wire 10 is energized, the heat generated is transferred to the heat-conducting base plate 11 through the heat-conducting base plate 11, and then transferred to the self-adhesive material in the feeding hopper 1, so that the material always remains active and avoids adhesion. The temperature sensor inside the heating base 2 can monitor the temperature of the heating base 2 in real time.

[0031] The delivery pump 9 is installed on the top of the top cover 6, and the delivery pipe connected to its bottom extends to the bottom of the inner cavity of the feeding barrel 1. The delivery pump 9 can deliver the self-adhesive raw material in the feeding barrel 1 to the production process. When the liquid level is lower than the set lower limit, the delivery pump 9 will stop drawing raw material to prevent the dry running phenomenon caused by insufficient raw material in the feeding barrel 1 and avoid damage to the delivery pump 9.

[0032] The level sensors 8 mounted on the mounting plate 7 are non-contact level sensors, and they are evenly distributed on the longitudinal mounting plate. By sensing the level of the liquid in the feeding tank 1, the level sensors 8 send the level information to the microcontroller in the delivery pump 9 in the form of an electrical signal.

[0033] The preferred non-contact liquid level sensor is a non-contact capacitive liquid level sensor, which uses liquid as a dielectric and reflects changes in liquid level by measuring changes in capacitance. The microcontroller determines whether to control the start and stop of the delivery pump 9 based on the received liquid level signal to ensure that there is always enough raw material in the feed tank, but without overflowing.

[0034] The alarm horn installed on the mounting plate 7 is linked to the lowest liquid level sensor 8. When the liquid level drops to the lowest level, the lowest liquid level sensor 8 will trigger the alarm horn to emit an alarm signal, reminding the operator that the raw materials in the feed tank are about to run out and need to be replenished, so as to prevent production interruption or dry running of the conveying pump due to the depletion of raw materials.

[0035] This self-adhesive label production feeding device realizes the functions of raw material storage, heating, conveying, liquid level monitoring and alarm, which can ensure the continuous and stable supply of raw materials during the self-adhesive label production process, while ensuring the activity and flowability of raw materials, avoiding production failures caused by abnormal temperature or liquid level, and improving production efficiency and equipment safety.
