Description

Technical Field

[0001] This utility model relates to the technical field of sewing machine skipped needle switch detection, specifically a switch detection device with skipped needle detection alarm function. Background Technology

[0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the fabric, so that one or more layers of fabric are interwoven or sewn together. In order to ensure stable production of clothes and stable sewing thread during the use of a sewing machine, it is necessary to have a device to detect whether the thread breaks during the sewing process. If the thread breaks, the machine should be stopped immediately to prevent damage to the machine or affect the sewing quality.

[0003] However, in the use of conventional detection devices, it is inconvenient to adjust the angle of the detection sensor according to the position of the seam, and the height of the detection sensor is mostly fixed, making it inconvenient to adjust the height of the sensor accordingly, and the stability of the connection between the seam and the sensor is not good.

[0004] Therefore, we provide a switch detection device with a jumper detection alarm function to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a switch detection device with a skipped stitch detection alarm function, in order to solve the problems mentioned in the background art, such as the inconvenience of adjusting the angle of the detection sensor according to the position of the sewing thread during use, the fixed height of the detection sensor, the inconvenience of adjusting the height of the sensor accordingly, and the poor stability of the connection between the sewing thread and the sensor.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a switch detection device with a skipped pin detection alarm function, comprising a fixed column, a support member, and a skipped pin detection sensor disposed below the support member;

[0007] Also includes:

[0008] The rear end of the support is provided with a mounting plate, and a skipped needle detection sensor is rotatably mounted on the lower end of the mounting plate. Both the upper and lower ends of the skipped needle detection sensor are provided with ceramic pieces, and the sewing thread passes through the skipped needle detection sensor and passes through the ceramic pieces at both ends.

[0009] The movable bracket has a connecting block fixedly connected to its left end, and the movable bracket forms an up-and-down sliding structure in the fixed column. The movable bracket, together with the connecting block and the support, drives the jumper detection sensor to form a lifting structure on the left side of the fixed column.

[0010] The above technical solution facilitates the installation, positioning, disassembly, and replacement of the skipped needle detection sensor. The sensor rotates at the bottom of the mounting plate, allowing for adjustment of its operating angle. The movable bracket slides up and down in the middle of the fixed column, enabling height adjustment of the sensor during use. The stitch thread passes through the sensor and through both ceramic plates, enhancing stability between the thread and the sensor and improving skipped needle detection. Furthermore, the sensor connects to an external alarm, transmitting a signal to the central processing unit (CPU) upon detecting a skipped needle. The CPU then activates the external alarm, raising staff awareness.

[0011] As a preferred embodiment of this utility model, a support member is fixedly connected to the left end of the connecting block, and the left end of the support member is provided with multiple through holes.

[0012] Using the above technical solution, a support is fixedly connected to the left end of the connecting block, and the left end of the support has multiple through holes, which support the jumper detection sensor below.

[0013] As a preferred technical solution of this utility model, the upper end of the mounting plate is fixedly connected to a mounting rod, and the mounting rod is inserted into the through hole on the right side. The front side of the mounting rod is threaded with a fastening nut for limiting the position, and the fastening nut is fitted and disposed at the rear end of the support member.

[0014] Using the above technical solution, a mounting rod is fixedly connected to the upper end of the mounting plate, and the mounting rod is inserted into the through hole on the right side. The front side of the mounting rod is threaded with a fastening nut for limiting the position. At the same time, the fastening nut is fitted to the rear end of the support, which facilitates limiting the position between the mounting plate and the support, and installing and positioning the jumper detection sensor.

[0015] As a preferred embodiment of this utility model, the jumper detection sensor and the mounting plate are limited by a fixing bolt that passes through the right end of the jumper detection sensor.

[0016] Using the above technical solution, the jumper detection sensor is limited by a fixing bolt that passes through the right end of the jumper detection sensor, which facilitates the limitation of the jumper detection sensor after the angle of the fastening nut is adjusted.

[0017] As a preferred embodiment of this utility model, the right end of the movable bracket is slidably connected to a connecting rod, and the outer surface of the connecting rod is sleeved with a spring. The left end of the connecting rod is fixedly connected to a fixing plate, and the fixing plate moves left and right within the movable bracket.

[0018] Using the above technical solution, a connecting rod is slidably connected to the right end of the movable bracket, and a spring is sleeved on the outer surface of the connecting rod. A fixing plate is fixedly connected to the left end of the connecting rod, and the fixing plate can move left and right in the movable bracket, which can drive the height of the jump needle detection sensor to be adjusted.

[0019] As a preferred technical solution of this utility model, both the front and rear ends of the fixing plate are engaged with the protrusions fixed at the corresponding positions at the front and rear ends of the fixing column, and the protrusions are equally spaced at the front and rear ends of the fixing column.

[0020] Using the above technical solution, the front and rear ends of the fixing plate are engaged with the corresponding protrusions fixed at the front and rear ends of the fixing column, and the protrusions are evenly spaced at the front and rear ends of the fixing column, which facilitates limiting the movement between the movable bracket and the fixing column after adjustment.

[0021] As a preferred embodiment of this utility model, the fixing plate and the fixing column are locked and limited by a connecting bolt passing through the right end of the fixing plate.

[0022] By adopting the above technical solution, the fixed plate and the fixed column are locked and limited by a connecting bolt passing through the right end of the fixed plate, which prevents the fixed plate from loosening and improves the control of the movable bracket.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] 1. This utility model provides a support member, a mounting rod, and a fastening nut. The mounting rod is inserted into the through hole on the right side, and the outer surface of the mounting rod is threaded with a fastening nut. The mounting rod and fastening nut facilitate the fixing of the mounting plate to the rear end of the support member, making it easy to install and support the jumper detection sensor.

[0025] 2. This utility model, by setting up an installation plate, a skipped needle detection sensor and a fixing bolt, allows the angle of the skipped needle detection sensor to be adjusted by rotating between the sensor and the installation plate.

The stitch passes through the skipped needle detection sensor and through the ceramic pieces at both ends, enabling better detection of skipped needles.

[0026] 3. This utility model, by setting up a movable bracket and a fixed plate, allows the movable bracket to slide up and down in the middle of the fixed column, thereby driving the jumper detection sensor to rise and fall, adjusting the height of the jumper detection sensor.

[0035] 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.

[0036] Please see Figures 1-6 The present invention provides the following technical solution.

[0037] To address the problems of existing detection devices, such as the inconvenience of adjusting the angle of the detection sensor based on the position of the seam, the fixed height of the detection sensor making it difficult to adjust accordingly, and the poor stability of the connection between the seam and the sensor, this solution provides a switch detection device with a skipped needle detection alarm function. The device includes a fixed column 1, a support member 3, and a skipped needle detection sensor 8 positioned below the support member 3. A mounting plate 5 is located at the rear end of the support member 3, and the skipped needle detection sensor 8 is rotatably mounted on the lower end of the mounting plate 5. Ceramic plates are located at both the upper and lower ends of the skipped needle detection sensor 8. The seam passes through the skipped needle detection sensor 8 and through the ceramic plates at both ends. A connecting block 2 is fixedly connected to the left end of a movable bracket 10, which forms a sliding structure within the fixed column 1. The movable bracket 10, together with the connecting block 2 and the support member 3, drives the skipped needle detection sensor 8 to form a lifting structure on the left side of the fixed column 1.

[0038] like Figure 1 , Figure 2 and Figure 5 As shown, the fixing column 1 is fixed to the frame. A connecting block 2 is provided at the upper end of the fixing column 1, and a support member 3 is fixedly connected to the left end of the connecting block 2. Multiple through holes 4 are provided on the left side of the support member 3. The mounting plate 5 drives the mounting rod 6 through the through holes 4 on the right end. Then, by rotating the fastening nut 7 threaded onto the outer surface of the mounting rod 6, the fastening nut 7 is fitted against the front side of the support member 3, thus facilitating the fixing of the mounting plate 5 to the rear end of the support member 3. Then, the skipped needle detection sensor 8 is placed on the front side of the lower end of the mounting plate 5. After rotating to a suitable angle, the skipped needle detection sensor 8 and the mounting plate 5 are stably limited by the fixing bolt 9. After installation, when the height of the skipped needle detection sensor 8 needs to be adjusted, such as... Figure 4 , Figure 5 and Figure 6 As shown, by pulling the connecting rod 11 to the right, the connecting rod 11 slides between itself and the movable bracket 10, and the connecting rod 11 drives the fixed plate 13 to move within the movable bracket 10. The fixed plate 13 compresses the spring 12, causing the spring 12 to undergo elastic deformation. At this time, the left end of the fixed plate 13 disengages from the protrusion 14, thereby releasing the restriction between the movable bracket 10 and the fixed column 1.

[0039] Then, pull the movable bracket 10 up or down, causing it to slide between itself and the fixed column 1. This, in turn, causes the skip pin detection sensor 8 to rise or fall on the left side of the fixed column 1, facilitating appropriate height adjustment of the sensor. When the appropriate height is reached, release the connecting rod 11. At this point, the spring 12 returns to its elastic deformation, pushing the fixed plate 13 to engage with the corresponding protrusion 14, thus limiting the movement between the movable bracket 10 and the fixed column 1. Then, rotate the connecting bolt 15 to lock the fixed plate 13 and the fixed column 1, improving the tightness of the limit between the movable bracket 10 and the fixed column 1 and preventing loosening. Figure 2 As shown, ceramic plates are provided at both the upper and lower ends of the skipped stitch detection sensor 8. The sewing thread passes through the skipped stitch detection sensor 8 and through the ceramic plates at both ends. When a skipped stitch occurs due to a broken thread, the skipped stitch detection sensor 8 detects it in time and transmits the detected information to the central processing unit. The central processing unit controls the machine to stop and activates the external alarm device to handle the alarm, raising the attention of the staff and enabling them to take timely action.

[0040] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
