Detailed Implementation

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Please see Figures 1 to 5 As shown, the embodiments provided by this utility model are as follows:

[0038] Example 1

[0039] A bag making machine with a material shortage alarm function includes a table 5, a pressing module 2 installed on the table 5, a cooling fan 3 installed at one end of the pressing module 2, a feeding module 1 installed on one end of the table 5 at the pressing module 2, and a winding module 4 installed on the end of the table 5 away from the feeding module 1.

[0040] Example 2

[0041] To facilitate material shortage detection alarms, for example, such as Figures 1 to 5As shown, this utility model also includes: a base 105 for the feeding module 1, a guide rod 104 for the base 105, two limiting shafts 109 for the base 105 and limited by the guide rod 104, and a material roll 103 and a support roller 106 are respectively rotatably mounted on the two limiting shafts 109. The material roll 103 is located above the support roller 106. The material roll 103 presses itself against the support roller 106 by its own weight, thereby preventing the material roll 103 from scattering. This design makes full use of the weight of the material roll 103 itself, and without the need for an additional pressing device, it can ensure that the material roll 103 will not scatter during the conveying process, thus ensuring the continuity and stability of production. Meanwhile, this design simplifies the equipment structure and reduces manufacturing costs. A support rod 101 is mounted at one end of the base 105, and an audible and visual alarm 102 is mounted at the top of the support rod 101. A distance sensor 107 is mounted at one end of the limiting shaft 109, on which the support roller 106 is mounted, via a clamp 108. A fixing hole 10802 is provided on the clamp 10802, through which a bolt is installed. After the clamp 108 is installed on the limiting shaft 109, it is locked in place through the fixing hole 10802. The cooperation of the bolt and the fixing hole 10802 further ensures the clamp 108's firmness on the limiting shaft 109. This design not only improves the stability of the equipment but also makes the installation and removal of the clamp 108 more convenient and quick. Meanwhile, the design of the bolts and fixing holes 10802 facilitates the tightening and adjustment of the clamp 108 to accommodate material coils 103 of different specifications and thicknesses. The clamp 108 has a boss 10803, and the distance sensor 107 is mounted on this boss 10803 via screws. The boss 10803 provides a stable support point for the distance sensor 107, enabling the sensor to more accurately measure the distance between the two limit shafts 109. Furthermore, the screw mounting method ensures a secure connection between the sensor and the clamp 108, preventing the sensor from shaking or falling off during measurement. This design not only improves measurement accuracy but also makes sensor installation and removal more convenient and quick, facilitating equipment maintenance. The limiting shaft 109 has slots 10901 at both ends, and the clamp 108 has a locking block 10801. The clamp 108 is fixed at both ends of the limiting shaft 109 through the cooperation of the locking block 10801 and the slot 10901. This design ensures that the clamp 108 is firmly installed on the limiting shaft 109, preventing rotation. Simultaneously, the cooperation of the slot 10901 and the locking block 10801 facilitates the installation and removal of the clamp 108, simplifying equipment maintenance. Furthermore, this design improves the overall stability and reliability of the equipment. The distance sensor 107 detects the distance between the limiting shaft 109 with the support roller 106 and the limiting shaft 109 with the material roll 103. The distance sensor 107 is electrically connected to the audible and visual alarm 102 via a controller.

[0042] Working principle:

[0043] The material roll 103 is mounted on the limiting shaft 109 of the feeding module 1 and pressed against the support roller 106 by its own gravity to prevent the material roll 103 from scattering. The distance sensor 107 is mounted on one end of the limiting shaft 109 where the support roller 106 is located, and is used to monitor the distance between the two limiting shafts 109 in real time, that is, the remaining thickness of the material roll 103.

[0044] As the material roll 103 continues to be used, its thickness gradually decreases, causing the distance between the two limit shafts 109 to gradually decrease. The distance sensor 107 can detect this distance change and transmit the signal to the controller. The controller determines whether the remaining amount of material roll 103 has reached a preset alarm threshold based on the received signal. If the alarm threshold is reached, the controller will trigger the audible and visual alarm 102 to remind the operator to replace the material roll 103 in time.

[0045] Upon hearing the alarm sound of the audible and visual alarm 102, the operator will immediately stop the bag-making machine. Then, the operator will open the protective cover or related components of the feeding module 1, remove the nearly used material roll 103, and replace it with a new material roll 103. After replacement, the operator will restart the bag-making machine to continue production.

[0046] It should be noted that the pressing module and the winding module are both commercially available products and are existing technologies. Their working principles and internal structures are known to those skilled in the art. This utility model only utilizes the functions of the above-mentioned components without improving their internal structures. Therefore, it will not be described in detail here.
