[0002] The vial cleaning machine is a device specially used for cleaning vials, and is commonly used in the fields of pharmaceuticals, biotechnology, etc. The feed screw is a key component of the equipment. The feed screw gradually transports the vials from the feed port to the cleaning area by rotating. The screw is usually designed in a spiral shape, which can effectively control the movement speed and direction of the bottle. Usually, only one vial is transported in each slot of the feed screw. When there are too many vials in the slot of the feed screw, an overload phenomenon will occur, causing the feed screw to jam and affect the vial transportation. Therefore, an overload device is currently set next to the feed screw for real-time detection.

[0003] At present, the overload device of the vial washing machine manufacturer is installed in the washing water tank. Because the water tank is filled with overheated injection water, the proximity switch sensor for controlling the overload is immersed in hot water for a long time, which will cause the feed screw failure rate to be high and the feed screw overload detection to be insensitive. Based on this, the utility model provides a feed screw overload device for the vial washing machine. Utility Model Content

[0028] Refer to the instruction manual Figure 1-7The utility model provides a feeding screw overload device for a vial cleaning machine, comprising an overload detection component 1 and a fixing component 2, wherein the overload detection component 1 comprises a proximity switch sensor 101 arranged at one side of the feeding screw, and the overload detection component 1 also comprises a detection column 102 arranged at the detection end of the proximity switch sensor 101, a driving shaft 103 is fixedly arranged at the front end of the detection column 102, the L-shaped plate 201 is fixed on a support seat 104, and the support seat 104 is fixed on the cleaning machine, a fixing plate 105 is fixedly arranged at one side of the support seat 104 close to the feeding screw, the fixing plate 105 is fitted with the feeding screw, a triangular block 106 is slidably arranged at the front end of the fixing plate 105, the rear end of the triangular block 106 is fixed to the front end of the driving shaft 103, a first spring 107 is connected to the top end of the support seat 104, and one end of the first spring 107 is connected to the front end of the detection column 102;

[0029] It also includes a fixing component 2, which is used to fix the proximity switch sensor 101. The fixing component 2 includes an L-shaped plate 201. The top and bottom ends of the L-shaped plate 201 are both provided with mounting holes 202. One end of the proximity switch sensor 101 passes through the mounting hole 202 at the top of the L-shaped plate 201.

[0030] When in use, first use the fixing component 2 to fix the proximity switch sensor 101 on the support base 104, so that the proximity switch sensor 101 is removed from the cleaning water tank of the vial washing machine, and the proximity switch sensor 101 is connected to the controller of the vial washing machine. The proximity switch sensor 101 is supported by the L-shaped plate 201 to be removed from the water to prevent the proximity switch sensor 101 from being affected by hot water, thereby extending the service life of the proximity switch sensor 101 and ensuring that the fault overload alarm is triggered in time.

[0031] The feeding screw continuously conveys the vials. If the feeding screw is not overloaded, the detection column 102 is facing the detection end of the proximity switch sensor 101. The proximity switch sensor 101 can detect the detection column 102, indicating that the feeding screw is not overloaded. When the vials in the feeding screw are overloaded, that is, there are too many vials in each slot of the feeding screw, the triangular block 106 is squeezed by the vials and moves backward, and the detection column 102 is driven by the drive shaft 103 to move away from the side of the proximity switch sensor 101, and the first spring 107 is pulled at the same time. At this time, the proximity switch sensor 101 cannot detect the detection column 102, indicating that the feeding screw is overloaded. After the staff handles it, the triangular block 106 is not subjected to force, and the detection column 102 is pulled to reset by the elastic force of the first spring 107 to prevent the feeding screw from getting stuck and affecting the feeding.

[0032] Refer to the instruction manual Figure 1-7The proximity switch sensor 101 is connected to the L-shaped plate 201 through a connecting component 3, and the connecting component 3 includes a slider 301, and the slider 301 is sleeved on the outer side of the detection end of the proximity switch sensor 101. One side of the slider 301 is sequentially provided with a first ring plate 302, a second ring plate 303 and a third ring plate 304 sleeved on the outer side of the detection end of the proximity switch sensor 101. The slider 301 and the third ring plate 304 are respectively arranged on both sides of the L-shaped plate 201, and the first ring plate 302 and the second ring plate 303 pass through the mounting hole 202 at the top of the L-shaped plate 201;

[0033] Furthermore, the first ring plate 302 is connected to the second ring plate 303 via a plurality of second springs 305, the third ring plate 304 is rotatably connected to the second ring plate 303, and the top and bottom ends of the third ring plate 304 are fixed with convex plates 306, which are in contact with the outer wall of the L-shaped plate 20102, so that the third ring plate 304 and the slider 301 are clamped on both sides of the L-shaped plate, thereby achieving the fixation of the proximity switch sensor 101;

[0034] The first ring plate 302 is provided with a plurality of circular grooves 4 on the surface of one end close to the second ring plate 303, and a plurality of second springs 305 are distributed in the plurality of circular grooves 4, and one end of each second spring 305 is fixed to the inner wall of the circular groove 4, and the other end of each second spring 305 is fixed to the outer wall of the second ring plate 303, and the elastic force of the plurality of second springs 305 is used to pull the third ring plate 304 and the convex plate 306 to always abut against the outer wall of the L-shaped plate 201, so as to improve the stability of the proximity switch sensor 101;

[0035] Moreover, spring latches 5 are fixedly penetrated through the outer walls on both sides of the front and rear sides of the slider 301, and slots 6 are opened on the outer walls on both sides of the front and rear sides of the proximity switch sensor 101, and the spring latches 5 are inserted into the slots 6;

[0036] The mounting hole 202 at the bottom of the L-shaped plate 201 is a long strip hole, and a threaded rod 7 is fixedly provided on the inner wall of the bottom of the support seat 104. The threaded rod 7 passes through the mounting hole 202 at the bottom of the L-shaped plate 201. A nut is threadedly connected on the threaded rod 7 to fix the L-shaped plate 201 and the support seat 104, so as to facilitate the left and right movement of the proximity switch sensor 101.

[0037] When installing the proximity switch sensor 101, first align the slider 301, the first ring plate 302, the second ring plate 303, and the third ring plate 304 with the detection end of the proximity switch sensor 101, and use the spring latch 5 to fix the slider 301 and the proximity switch sensor 101 together, and then align the third ring plate 304, the second ring plate 303, and the first ring plate 302 with the mounting hole 202 at the top of the L-shaped plate 201 to make the proximity switch sensor 101 face the detection column 102, and then rotate the third ring plate 304 to make the two convex plates 306 respectively rotate to the position above one side and below one side of the mounting hole 202 (such as Figure 4 As shown), the elastic force of the second spring 305 is used to pull the second ring plate 303, the third ring plate 304 and the two protruding plates 306, so that the two protruding plates 306 and the slider 301 are firmly in contact with the outer wall of the L-shaped plate 201. The two protruding plates 306 and the slider 301 are similar to clips, so that the proximity switch sensor 101 is firmly fixed on the L-shaped plate 201 for use.

[0038] By pulling the convex plate 306 away from the L-shaped plate 201, the proximity switch sensor 101 can be pushed to move forward and backward.
