Technical Field

[0001] This utility model relates to the field of alarm device technology, specifically an alarm device for preventing spirals from straightening. Background Technology

[0002] PVC hollow spiral pipes feature a "double-layer, hollow, counter-clockwise rotating inner wall" structure. This design is intended to reduce drainage speed, provide sound insulation, and decrease noise during high-rise building drainage. The production process primarily relies on a motor and chain driving a transmission shaft to rotate the mold, thereby creating the counter-clockwise thread on the inner wall of the product.

[0003] However, in actual production, the mold transmission mechanism is prone to damage and stoppage, which causes the internal threads of the product to straighten, thus losing its function of reducing water flow speed and noise, resulting in product scrap and cost loss. Therefore, it is necessary to improve the alarm device to prevent the straightening of the spiral to solve the above problems. Utility Model Content

[0020] 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.

[0021] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] Example:

[0023] Please see Figure 1-5 This utility model provides a technical solution: an alarm device to prevent spiral straightening, including a support frame 1 placed on one end of the mold drive shaft, a vertical frame 4 set on the front of the mold drive shaft and a pipe processing device 5, a buzzer alarm 6 fixedly installed on the top of the pipe processing device 5, an alarm installation mechanism 2 set on the outside of the vertical frame 4, and a mold drive mechanism 3 set on the back of the alarm installation mechanism 2.

[0024] Furthermore, the installation alarm mechanism 2 includes a connecting frame 21, which is sleeved on the outside of the upright frame 4. A long bolt 22 is threaded inside the connecting frame 21, and a connecting strip 23 is provided on the outside of the long bolt 22. A small dedicated speed monitoring relay 24 is fixedly installed on the front of the connecting strip 23, and a sliding groove strip 25 is fixedly installed on the back of the connecting frame 21. A sliding mounting plate 26 is slidably installed inside the sliding groove strip 25, and a small bolt 27 moves through the sliding mounting plate 26. A photoelectric sensor 28 is installed on the external thread of the small bolt 27. Through the installation alarm mechanism 2, the photoelectric sensor 28 is fixedly installed by installing the connecting frame 21 and the connecting strip 23. The photoelectric sensor 28 monitors the rotation of the second sprocket 34, thus providing timely warnings when the transmission structure is damaged, preventing product scrapping and significant losses.

[0025] Furthermore, holes are provided at the corresponding positions of the connecting strip 23 and the long bolt 22, and the long bolt 22 moves through the holes provided inside the connecting strip 23. Through the long bolt 22 passing through the holes inside the connecting strip 23, the connecting frame 21 and the connecting strip 23 can be fastened together, thereby making the connecting frame 21 and the connecting strip 23 tightly fixed to the outside of the upright frame 4.

[0026] Furthermore, a limiting groove is provided inside the slide bar 25, and the sliding mounting plate 26 is slidably installed inside the limiting groove provided inside the slide bar 25. Through the setting of the limiting groove, the position of the photoelectric sensor 28 can be adjusted according to the bonding position of the special reflective patch 36, so as to accurately collect the signal generated by the rotation of the mark.

[0027] Furthermore, the mold transmission mechanism 3 includes a motor 31, which is fixedly installed on the bottom inner side of the support frame 1. A sprocket 32 ​​is fixedly installed on the front of the transmission shaft of the motor 31. A chain 33 is installed on the outside of the sprocket 32. A sprocket 34 is installed on the end of the chain 33 away from the sprocket 32. A shaft connector 35 is fixedly installed on the back of the sprocket 34. A special reflective patch 36 is glued to the front of the sprocket 34 with double-sided adhesive. Through the mold transmission mechanism 3, the transmission shaft of the mold can be driven to rotate, thereby producing counterclockwise threads. At the same time, the special reflective patch 36 is driven to rotate to transmit rotation signals.

[0028] Furthermore, the bonding position of the special reflective patch 36 corresponds to that of the photoelectric sensor 28, and 10mm foam double-sided adhesive is used. By using adhesive, the special reflective patch 36 can be installed quickly and freely. This also ensures that the vibration of the sprocket 2 34 will not affect the special reflective patch 36, avoiding the limitation that the bolt installation vibration will cause it to fall off.

[0029] In actual operation, when using this device, firstly, install the buzzer alarm 6 on the top of the pipeline treatment device 5. It can also be installed on the top of other equipment; it is not limited to this equipment and can be installed in any conspicuous location. Next, fit the connecting frame 21 onto the outside of the upright frame 4, allowing the long bolt 22 to pass through the connecting strip 23 and enter the interior of the connecting frame 21. After determining the installation height of the connecting frame 21, tighten the long bolt 22 to complete the fixing of the connecting frame 21. At this time, the small dedicated speed monitoring relay 24 is also fixed. Tighten the small bolt 27 so that it passes through the sliding mounting plate 26 and enters the interior of the photoelectric sensor 28. Install the photoelectric sensor 28 on one side of the sliding mounting plate 26, which has a relatively long space reserved. Therefore, it will not affect the wires of the photoelectric sensor 28. At the same time, the vertical frame 4 and the support frame 1 maintain sufficient spacing. The transmission of sprocket 1 32, chain 33 and sprocket 2 34 will not affect the guide. At this time, the special reflective patch 36 is glued to the front of sprocket 2 34 with double-sided adhesive. The sliding mounting plate 26 is slid and the position of the photoelectric sensor 28 is adjusted. Due to the transmission of sprocket 1 32, chain 33 and sprocket 2 34, the shaft connector 35 will be driven to rotate, causing the mold transmission shaft to rotate and causing the inside of the mold to rotate, generating counterclockwise threads. Therefore, when sprocket 2 34 rotates, it will also drive the special reflective patch 36 to rotate. The photoelectric sensor 28 can be adjusted to the position corresponding to the special reflective patch 36, so that the special reflective patch 36 will pass the photoelectric sensor 28 every time it rotates.

[0030] During operation, the small dedicated speed monitoring relay 24 is set to a standard speed. Since the rotation speed of the second sprocket 34 is constant, the sensor outputs a pulse signal every time the marker rotates past the sensor. When the main shaft stops rotating, the speed is lower than the set value and exceeds the set delay time, that is, when the speed of the dedicated reflective patch 36 passing the photoelectric sensor 28 is lower than the standard value, or when no pulse is detected after the response time, the contacts of the small dedicated speed monitoring relay 24 are activated, triggering the buzzer alarm 6 installed at the highest point and in a prominent position in the production area to issue a red alarm.

[0031] It should be noted that the entire system is powered by an industrial switching power supply (24V DC). All wiring and installation must be designed with protection, vibration resistance, interference prevention, and reliability in mind. This solution has a controllable cost and can effectively solve the problem of thread straightening and scrap caused by mold stoppage, significantly reducing losses. Before implementation, a detailed site survey must be conducted and the most suitable installation location must be selected. Among them, the small dedicated speed monitoring relay 24 is a speed monitoring relay of model SDM45, and the photoelectric sensor 28 is a photoelectric sensor of model CD33-30N-422.

[0032] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
