Description

Technical Field

[0001] This utility model relates to a straw detection device and belongs to the technical field of straw detection devices. Background Technology

[0002] When customers use straw pasting machines, the actual success rate is not 100%. It may be affected by factors such as the quality of the straw, the operator's adherence to the equipment, and the maintenance of the equipment. A small number of straws will not be pasted and will fall off. If these products with unpainted straws are put on the market, consumers may complain, which will damage the company's image. Therefore, many manufacturers are paying more and more attention to this issue and looking for solutions.

[0003] Most of the existing products on the market are optical imaging detection systems. The principle is to compare the product with images to see if there are straws or if the straws are not properly attached. The advantage of this system is that in addition to detecting the presence of straws, it can also detect products with crooked straws. However, the system is expensive, almost the same price as a straw attaching machine. As an auxiliary device for a straw attaching machine, it is generally unacceptable to customers. Furthermore, this system is not suitable for colorless and transparent straws and cannot detect them correctly.

[0004] This utility model proposes a new solution to the above problems. Utility Model Content

[0005] The main purpose of this utility model is to solve the problems of the high price of the system, which is generally unacceptable to customers as an auxiliary device for the tube applicator, and the system is not applicable to colorless and transparent straws, making it impossible to detect them correctly. Therefore, this straw detection device is provided.

[0006] The objective of this utility model can be achieved by adopting the following technical solution:

[0007] A straw detection device includes a transmission base and a conveying track disposed on the upper surface of the transmission base. A first mounting frame is fixedly connected to the surface of the transmission base. A mounting rod is fixedly connected to the upper surface of the first mounting frame. A connecting sleeve is rotatably connected to the top of the mounting rod. A mounting plate is fixedly connected to the surface of the connecting sleeve. A detection wheel is fixedly connected to the upper surface of the mounting plate. A magnification lever is fixedly connected to the surface of the connecting sleeve. A spring is fixedly connected to the surface of the magnification lever. A reset switch is fixedly connected to the surface of the first mounting frame.

[0008] Preferably, a first photoelectric sensor is provided on the first mounting bracket, and the detection end of the first photoelectric sensor is located above and behind the magnification lever.

[0009] Preferably, a second photoelectric sensor is provided on the first mounting bracket, and the second photoelectric sensor is located below.

[0010] Preferably, a second mounting bracket is fixedly connected to the surface of the transmission base, and a drive wheel is provided on the upper surface of the second mounting bracket.

[0011] Preferably, a support rod is fixedly connected to the upper surface of the second mounting bracket, and an electrical box is fixedly connected to one end of the support rod.

[0012] Preferably, Tetra Pak packets are arranged on the conveying track.

[0013] Preferably, a fixing frame is fixedly connected to the surface of the transmission base, and an air jet removal nozzle is fixedly connected to the surface of the fixing frame.

[0014] Preferably, a baffle is fixedly connected to the upper surface of the first mounting bracket, and the detection wheel is located inside the baffle.

[0015] The beneficial technical effects of this utility model are as follows: After the Tetra Pak cartons are attached with the tube, they move forward on the conveyor track. When passing the straw detection wheel, the drive wheel rotates in the same direction to propel them through the gap between the drive wheel and the detection wheel. The size of the gap is equal to the thickness of the Tetra Pak cartons. If the straw has already been attached, the thickness will be larger than the gap between the two wheels, causing compression when passing through the gap. Since one side of the drive wheel is fixed, only one side of the detection wheel can be opened. When the detection wheel is opened, the mounting plate rotates, causing the connecting sleeve and mounting rod to rotate, further causing the magnification lever to swing accordingly. At this time, the magnification lever stretches the spring. This causes the spring to deform elastically, generating tension, which in turn pulls the reset switch, sending a signal. If a straw is present, the bag is allowed to pass. After the Tetra Pak bag passes, the detection wheel resets under the tension of the spring, and the reset switch automatically resets. If the straw is not attached to the incoming Tetra Pak bag, it will not squeeze the detection wheel when passing through the gap between the drive wheel and the detection wheel, and the amplification lever will not move. The proximity reset switch will not be triggered, confirming that there is no straw. When the Tetra Pak bag reaches the air removal nozzle, it will be blown away by the air removal nozzle and leave the conveyor track. It is inexpensive and suitable for transparent straws.

[0023] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0024] like Figures 1-6 As shown, the straw detection device provided in this embodiment includes a transmission base 1 and a conveying track 2 disposed on the upper surface of the transmission base 1. The conveying track 2 drives the Tetra Pak 15 to move. A first mounting bracket 3 is fixedly connected to the surface of the transmission base 1. A mounting rod 4 is fixedly connected to the upper surface of the first mounting bracket 3. A connecting sleeve 5 is rotatably connected to the top of the mounting rod 4. A mounting plate 6 is fixedly connected to the surface of the connecting sleeve 5. A detection wheel 7 is fixedly connected to the upper surface of the mounting plate 6. A magnifying pendulum 8 is fixedly connected to the surface of the connecting sleeve 5. When the detection wheel 7 is spread open, the mounting plate 6 rotates, causing the connecting sleeve 5 and the mounting rod 4 to rotate, further causing the magnifying pendulum 8 to swing accordingly. One end of the magnifying pendulum 8 moves a greater distance. A spring 9 is fixedly connected to the surface of the first mounting bracket 8. A reset switch 10 is fixedly connected to the surface of the first mounting bracket 3. A first photoelectric sensor 11 is installed on the first mounting bracket 3 to detect whether there is a straw on the Tetra Pak 15. The detection end of the first photoelectric sensor 11 is located above and behind the magnification lever 8. A second photoelectric sensor 17 is installed on the first mounting bracket 3 to detect the position of the Tetra Pak 15. The second photoelectric sensor 17 is located below. A second mounting bracket 12 is fixedly connected to the surface of the transmission base 1. A drive wheel 13 is installed on the upper surface of the second mounting bracket 12. A Tetra Pak 15 is installed on the conveying track 2. A fixing bracket 18 is fixedly connected to the surface of the transmission base 1. An air removal nozzle 19 is fixedly connected to the surface of the fixing bracket 18.

[0025] In this embodiment, as Figure 1 , Figure 2 and Figure 5 As shown, a support rod 14 is fixedly connected to the upper surface of the second mounting bracket 12, and an electrical box 16 is fixedly connected to one end of the support rod 14. A cover 20 is fixedly connected to the upper surface of the first mounting bracket 3. The detection wheel 7 is located inside the cover 20. The cover 20 shields the first photoelectric sensor 11 and the second photoelectric sensor 17 to protect them.

[0026] In this embodiment, as Figures 1-6 As shown, the working principle of the straw detection device provided in this embodiment is as follows:

[0027] After the tube is attached, the Tetra Pak 15 moves forward on the conveyor track 2. When it passes the straw detection, the drive wheel 13 rotates in the same direction to propel it through the gap between the drive wheel 13 and the detection wheel 7. The size of the gap is equal to the thickness of the Tetra Pak 15. If the straw is already attached, the thickness will be larger than the gap between the two wheels, causing it to be squeezed when passing through the gap. One side of the drive wheel 13 is fixed, so only one side of the detection wheel 7 can be opened. When the detection wheel 7 is opened, the mounting plate 6 rotates, causing the connecting sleeve 5 and the mounting rod 4 to rotate, further causing the magnification lever 8 to swing. At this time, the magnification lever 8 stretches the spring 9, causing... Spring 9 undergoes elastic deformation, generating tension, which in turn pulls reset switch 10, sending a signal to allow passage if a straw is present. After Tetra Pak 15 passes, the detection wheel 7 resets under the tension of spring 9, and reset switch 10 automatically resets. If the straw of the incoming Tetra Pak 15 is not attached, it will not squeeze the detection wheel 7 when passing through the gap between drive wheel 13 and detection wheel 7, and the amplification lever 8 will not move. The reset switch 10 will not be triggered, confirming that there is no straw. When Tetra Pak 15 reaches the air removal nozzle 19, it will be blown away by the air in the air removal nozzle 19, causing it to leave the conveyor track 2.

[0028] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
