[0034] The length of the air-conditioning heat preservation pipe is a measurement unit of incoming material. For the purchaser of the air-conditioning heat preservation pipe, the length of the air-conditioning heat preservation pipe needs to be measured after the air-conditioning heat preservation pipe is delivered, so as to verify whether the air-conditioning heat preservation pipe purchased has a shortage (i.e., the measured length of the air-conditioning heat preservation pipe is less than the actual purchased length), and then control the quality of the incoming material of the air-conditioning heat preservation pipe. At present, the length of the air-conditioning heat preservation pipe cannot be measured by using conventional weighing methods due to its foaming characteristics and physical characteristics, and can only be measured manually. The manual measurement of the air-conditioning heat preservation pipe is to measure the length of the air-conditioning heat preservation pipe in a natural state by using a measuring tape. However, this measurement method has low overall measurement efficiency and cannot meet the needs of rapid and batch measurement. In addition, measurement errors are more likely to occur, and the accuracy is low, which is not conducive to controlling the quality of the incoming material of the air-conditioning heat preservation pipe.

[0035] To solve the above problems in the prior art, the embodiment of the present application provides a length measuring device for a flexible pipe. The length of the pipe to be measured is measured by a length measuring device through a guide conveying mechanism between a unwinding mechanism and a winding mechanism. This method can greatly improve the measurement efficiency of the pipe to be measured, can meet the needs of rapid and batch measurement, and is not prone to measurement errors, greatly improves the accuracy of the measurement results, and is very conducive to controlling the quality of the incoming material of the air-conditioning heat preservation pipe.

[0036] Embodiment one Referring to Figure 1 The length measuring device for a flexible pipe of the embodiment of the present application comprises: The unwinding mechanism 21 is used for unwinding the pipe to be measured 60. The winding mechanism 22 is used for winding the pipe to be measured 60. The guide conveying mechanism 30 is arranged between the unwinding mechanism 21 and the winding mechanism 22, and is used for guiding and conveying the pipe to be measured 60. The length measuring device (not shown in the figure) is arranged on the guide conveying mechanism 30, and is used for measuring the length of the pipe to be measured 60 when the guide conveying mechanism 30 guides and conveys the pipe to be measured 60.

[0037] In this embodiment, the pipe to be measured 60 is a flexible pipe, which can be bent or wound up. For example, the pipe to be measured 60 can be an air-conditioning heat preservation pipe, a plastic water pipe or other flexible pipes. In this embodiment, the pipe to be measured 60 is an air-conditioning heat preservation pipe.

[0038] In the embodiment, it can be understood that the unwinding mechanism 21 and the winding mechanism 22 can be used to wind the pipe to be measured 60, when the unwinding mechanism 21 is used to unwind the pipe to be measured 60, the pipe to be measured 60 is wound on the unwinding mechanism 21 before the pipe to be measured 60 is unwound; when the winding mechanism 22 is used to wind the pipe to be measured 60, the winding mechanism 22 winds the pipe to be measured 60 to wind the pipe to be measured 60.

[0039] In the embodiment, the guide mechanism 30 is arranged between the unwinding mechanism 21 and the winding mechanism 22, and is used to guide or transport the pipe to be measured 60. More specifically, the guide mechanism 30 is used to guide the pipe to be measured 60 on the unwinding mechanism 21 to the winding mechanism 22 for winding.

[0040] In the embodiment, the length measuring device is an electronic length measuring device. For example, the length measuring device can be a meter counter or other electronic length measuring device. In the embodiment, when the guide mechanism 30 guides the pipe to be measured 60, the meter counter can start measuring the length of the pipe to be measured 60 when the starting end of the pipe to be measured 60 passes through the meter counter, and end the length measurement of the pipe to be measured 60 when the ending end of the pipe to be measured 60 passes through the meter counter, thereby measuring the length of the pipe to be measured 60. In the embodiment, the length measuring device is connected to a display, and the length of the pipe to be measured 60 measured by the length measuring device can be displayed on the display. Preferably, the display can be provided with a control panel having control buttons, and the control buttons of the control panel can be used to control the length measuring device for the flexible pipe. In other embodiments, the length measuring device can also be an electronic length measuring device with a display.

[0041] The length measuring device for flexible pipe in the embodiment of the present application can wind the pipe to be measured 60 on the unwinding mechanism 21, unwind the pipe to be measured 60 through the unwinding mechanism 21, guide the unwound pipe to be measured 60 to the winding mechanism 22 through the guide mechanism 30, and wind the pipe to be measured 60 on the winding mechanism 22 to collect the material. The length of the pipe to be measured 60 can be measured through the length measuring device during the guiding process of the guide mechanism 30. Compared with the manual measurement method, this method is more convenient to operate. The unwinding and winding of the pipe to be measured 60 are both in the winding mode, so the staff does not need to wind the pipe to be measured 60 after the measurement is completed, which is very convenient. At the same time, this method can be very convenient to measure the length of the pipe to be measured 60, significantly improve the measurement efficiency of the pipe to be measured 60, can meet the needs of rapid and batch measurement, and is not easy to cause measurement error, greatly improves the accuracy of the measurement result, and is very beneficial to control the quality of the incoming material of the air-conditioning heat preservation pipe.

[0043] In the above structure, the bearing rack 10 can facilitate the arrangement of the unwinding mechanism 21 and the winding mechanism 22, and make the length measuring device for flexible pipe become an integrated device, which is divided into a separate device. In this way, the length measuring device for flexible pipe can be conveniently carried and used.

[0044] In other embodiments, the length measuring device for flexible pipe in the embodiment of the present application can also not use the bearing rack 10. The length measuring device for flexible pipe in the embodiment of the present application can adopt a separate structure, that is, the unwinding mechanism 21, the winding mechanism 22 and the guide mechanism 30 can be arranged on separate bearing supports.

[0045] In the embodiment, preferably, the guiding mechanism 30 can be provided with a material sensor (not shown in the figure) which can be used to sense whether there is the pipe 60 to be measured at its position, the material sensor is connected with the length measurer, the length measurer can start to measure the length of the pipe 60 to be measured when the material sensor senses that there is the pipe 60 to be measured (i.e. when the starting end of the pipe 60 to be measured passes), and end the length measurement of the pipe 60 to be measured when the material sensor senses that there is no pipe 60 to be measured (i.e. after the end of the pipe 60 to be measured passes), thereby measuring the length of the pipe 60 to be measured; for example, the material sensor can be a photoelectric sensor or other material sensor which can detect whether there is an object.

[0048] In the embodiment, the length measurer can be arranged on the carrying frame 31 at a position corresponding to the pipe guiding gap formed between the two synchronous belt assemblies 32.

[0049] In the above-mentioned structure, the carrying frame 31 can facilitate arranging the guiding mechanism 30 between the unwinding mechanism 21 and the winding mechanism 22, and the carrying frame 31 can better carry the synchronous belt assemblies 32; the pipe guiding gap formed by the two synchronous belt assemblies 32 can better ensure the stability of the guiding process of the pipe 60 to be measured, and avoid the up-and-down movement of the pipe 60 to be measured when guided by the two synchronous belt assemblies 32, thereby further improving the accuracy of the measurement result.

[0050] It should be noted that in other embodiments, the guide mechanism 30 can also adopt other structures, for example, the guide mechanism 30 can also adopt a conveying belt assembly and a liftable pressing plate assembly arranged above the conveying belt assembly, and a pipe guide gap is formed between the conveying belt assembly and the pressing plate assembly; here, other possible structures of the guide mechanism 30 are not exemplified, and it can be understood that the guide mechanism 30 in the embodiment adopts the technical idea of clamping and conveying the pipe to be measured 60 up and down, and other changes to the guide mechanism 30 through the same technical idea are also covered in the guide mechanism 30 in the embodiment.

Specifically, the structure of the mounting support 312 is as shown in Figures 3 to 5 , which will not be described and expanded here.

[0053] In the above structure, the mounting frame 31 is divided into the mounting frame body 311 and the two mounting supports 312, which can facilitate the production of the mounting frame 31, and can facilitate the installation of the synchronous belt assembly 32 on the mounting frame 31. When installing, the synchronous belt assembly 32 can be first installed on the mounting support 312, and then the mounting support 312 is installed on the mounting frame body 311.

[0060] Embodiment Four With reference to Figure 1 and Figure 2 In the above embodiment one to embodiment three, on the basis of any one of the embodiments, the difference between the present embodiment and any one of embodiment one to embodiment three is that the length measuring device for flexible pipe of the present embodiment, the unwinding mechanism 21 and the winding mechanism 22 all include the mounting wheel disc 201, the connecting shaft 202 and the adjusting rod 203, The mounting wheel disc 201 has two, and the two mounting wheel discs 201 are oppositely arranged; the connecting shaft 202 is connected between the two mounting wheel discs 201; The adjusting rod 203 has a plurality of, and the plurality of adjusting rods 203 are all rotatably connected between the two mounting wheel discs 201, and the plurality of adjusting rods 203 are distributed and arranged around the connecting shaft 202; The two mounting wheel discs 201 are all provided with a plurality of adjusting guide rails 2011 corresponding to the plurality of adjusting rods 203, the plurality of adjusting guide rails 2011 are arranged in the radial direction of the mounting wheel disc 201, and the plurality of adjusting guide rails 2011 are annularly distributed; the adjusting rod 203 is slidably connected to the adjusting guide rail 2011.

Understandably, in actual use, the unwinding mechanism 21 and the winding mechanism 22 can also be used in reverse, as long as one of them is used for unwinding the pipe to be measured 60, and the other is used for winding the pipe to be measured 60; In the present embodiment, the mounting wheel disc 201 is in a circular disc structure; the connecting shaft 202 is connected between the two mounting wheel discs 201, that is, one end of the connecting shaft 202 is connected to one mounting wheel disc 201, and the other end of the connecting shaft 202 is connected to the other mounting wheel disc 201, so that the connecting shaft 202 is located between the two mounting wheel discs 201; In the present embodiment, the position of the adjusting rod 203 on the adjusting guide rail 2011 can be adjusted by sliding the adjusting rod 203, and thus the diameter of the pipe to be measured 60 when it is wound up can be adjusted.
