Description

Technical Field

[0001] The present invention relates to the technical field of product detection, and particularly to a contact temperature measuring device for a heat preservation cup. Background Art

[0002] After the production of heat preservation cups, it is necessary to detect their heat preservation performance. Currently, the detection of the heat preservation performance of heat preservation cups is usually carried out by heating the inner wall to raise the temperature and then detecting the outer wall temperature. Among the existing detection methods, one type is the manual sampling inspection method, that is, manually placing the heat preservation cup to be sampled on the heating table, heating the inside of the heat preservation cup, and then touching the outer shell of the heat preservation cup by hand. If the outer shell does not heat up, it proves that the heat preservation performance is good and the heat inside the heat preservation cup has not been transferred to the outside, then it is determined that the heat preservation cup is qualified for heat preservation. Otherwise, it proves that the heat preservation cup is unqualified, and it depends on manual experience to determine whether it is qualified. The other type is to use an infrared temperature sensor. After heating the inside of the heat preservation cup for a certain period of time, a non-contact single-point infrared temperature sensor is used to measure the outer wall of the heat preservation cup. If the outer wall temperature is higher than the set value, it proves that the heat heated inside the heat preservation cup has been transferred to the outer wall of the heat preservation cup, and the heat preservation performance of the heat preservation cup is unqualified. Otherwise, it proves that the heat preservation cup is qualified. The above two types, one relies on manual touch judgment with errors, and the other is single-point temperature measurement of the outer wall of the heat preservation cup, with problems of incomplete measurement and inability to measure multiple areas of the heat preservation cup, resulting in inaccurate detection, that is, both of the above two existing technical solutions have problems of inaccurate detection.

Detailed implementation manners

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0020] The purpose of the present invention is to provide a contact temperature measurement device for thermos cups to solve the problems existing in the above-mentioned prior art and improve the detection accuracy of thermos cups.

[0021] To make the above objects, features, and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Currently, when detecting the heat preservation performance of a heat preservation cup, the manual touch detection or the single-point non-contact detection method using an infrared sensor both have the problems of low efficiency and inaccurate detection; to solve this problem, the present invention provides a contact temperature measurement device for a heat preservation cup, as Figures 1 to 6 shown, including a frame 1, on which a closed conveying chain group 5 is provided. The conveying chain group 5 moves along the length direction of the frame 1. Mounting holes 502 are provided on the chain plates 501 of the conveying chain group 5, and an inverted heat preservation cup 7 can be placed on the mounting holes 502. A heating mechanism 6 is arranged inside the frame 1, which has a vertically arranged air outlet pipe 605. When the mounting hole 502 drives the heat preservation cup 7 to move to directly above the air outlet pipe 605, the heating mechanism 6 can blow hot air into the heat preservation cup 7 through the air outlet pipe 605, thereby increasing the internal temperature of the heat preservation cup 7 and simulating the state of containing hot water. At both ends of the top of the frame 1, an inlet temperature measurement mechanism 3 and an outlet temperature measurement mechanism 4 are respectively arranged. Before heating, the inlet temperature measurement mechanism 3 can clamp the outer wall of the heat preservation cup 7 on the conveying chain group 5 and measure its temperature, and the measured value is transmitted to the control end; the outlet temperature measurement mechanism 4 can clamp the heated heat preservation cup 7 on the conveying chain group 5 and measure its temperature, and the measured temperature value can be transmitted to the control end. The control end can detect the heat preservation performance of the heat preservation cup 7 by comparing the two temperature differences. When the two differences are within a reasonable range, it proves that the heat preservation performance of the heat preservation cup 7 is good, and the temperature of the heat preservation cup 7 heated by hot air inside has not been transmitted to the outer wall of the cup; if the two temperature differences are large and exceed the reasonable range, it proves that the heat preservation performance of the heat preservation cup 7 is poor, and the temperature inside the cup has been transmitted to the outer wall of the cup. The control end uses a computer, which is built-in with known and mature software programs, can compare and analyze the two temperature measurement values, and can send a signal in time when detecting unqualified products, facilitating the subsequent rejection of defective products.

[0023] To facilitate the positioning during loading, an upper part positioning baffle 2 is fixedly arranged at one end of the top of the frame 1 close to the inlet temperature measurement mechanism 3. The upper part positioning baffle 2 is horizontally arranged on the top of the conveying chain group 5, and a plurality of arc-shaped positioning grooves are provided inside the upper part positioning baffle 2; the vertical projection of the virtual circle where the plurality of arc-shaped positioning grooves are located can coincide with the plurality of mounting holes 502 on the strip plate moving below the upper part positioning baffle 2 one by one. When the detection starts, the heat preservation cup 7 to be tested is arranged in contact with the arc-shaped positioning grooves, and the bottom opening of the heat preservation cup 7 can be placed on the mounting holes 502 on the chain plate 501 moving here.

[0024] In order to stably place the heat preservation cup 7, the chain plate 501 in this embodiment adopts a plurality of sequentially hinged strip plates. The plurality of strip plates are sequentially connected into a ring shape. A plurality of mounting hole positions 502 are provided on each strip plate. The opening of the heat preservation cup 7 can be stably buckled on the mounting hole positions 502. An air outlet hole 505 is provided at the central position of the mounting hole positions 502, and a return air hole 506 is annularly provided outside the air outlet hole 505. After the heat preservation cup 7 is buckled on the mounting hole positions 502, the opening of the heat preservation cup 7 can buckle the air outlet hole 505 and the return air hole 506. Thus, the air outlet pipe 605 can blow hot air into the heat preservation cup 7 through the air outlet hole 505 to realize heating of the inside of the heat preservation cup 7. At the same time, after the hot air enters the bottom inside the heat preservation cup 7, it flows downward along the inner wall of the cup and is discharged through the return air hole 506 annularly provided outside the air outlet hole 505, avoiding excessive hot air pressure inside the cup. In order to realize the stable transportation of the heat preservation cup 7, the conveying chain group 5 in this embodiment includes a first sprocket 503, a second sprocket 504 and a chain plate 501. Two first sprockets 503 of the same height are provided above the frame 1, and two second sprockets 504 of the same height are provided below the frame 1. One end of the closed chain plate 501 is connected with a closed chain, and the chain is wound around the first sprocket 503 and the second sprocket 504 in a closed manner. One of the second sprockets 504 is drivingly connected with a driving motor. Thus, when the driving motor rotates, it can drive the second sprocket 504 to rotate, and then drive the chain to rotate. The chain can drive the chain plate 501 to rotate. When the strip plate of the chain plate 501 rotates between the two first sprockets 503, it is in a horizontal state. This is the working position of the chain plate 501. At this time, the heat preservation cup 7 can be placed and transported. The position of the inlet temperature measuring mechanism 3 is set at one end of the frame 1 and close to one of the first sprockets 503. The outlet temperature measuring mechanism 4 is located at the other end of the frame 1 close to the other first sprocket 503. In order to make the operation of the chain plate 501 more stable, a closed chain is provided on both sides of the chain plate 501. The two chains each have their corresponding first sprocket 503 and second sprocket 504. In this way, both ends of the chain plate 501 are driven synchronously by the two chains, and the operation is more stable. After the detection of the heat preservation cup 7 is completed, a temporary storage table is provided at the end of the frame 1. The detected heat preservation cup 7 can be placed on the temporary storage table for subsequent manual or mechanical hands to store the qualified products and unqualified products separately. After the heat preservation cup 7 is placed on the temporary storage table, the chain will bypass the position where the first sprocket 503 is located and drive the chain plate 501 to continue to rotate downward, and finally return to the position of the first sprocket 503 close to the inlet temperature measuring mechanism 3, so that the chain plate 501 participates in placing the heat preservation cup 7 again for detection.

[0025] In order to improve the heating efficiency, the heating mechanism 6 of this embodiment includes a heating box 601 fixedly arranged in the frame 1. A heating device is provided in the heating box 601. In this embodiment, the heating device uses an electric heating tube 603; an air outlet box 602 is arranged in the heating box 601. The air outlet box 602 is small in volume and is located above the electric heating tube 603. One end of the heating box 601 is provided with a heating circulation fan 604. The air inlet of the heating circulation fan 604 is communicated with the inside of the heating box 601, and the air outlet of the heating circulation fan 604 is communicated with the inside of the air outlet box 602. Therefore, the heating circulation fan 604 can send the hot air heated by the electric heating tube 603 in the heating box 601 into the air outlet box 602; a plurality of air outlet pipes 605 are arranged on the top of the air outlet box 602. The plurality of air outlet pipes 605 are arranged in rows along the length direction of the frame 1. The number of air outlet pipes 605 in each row is the same as the number of mounting holes 502 on the strip plate. After the top openings of the air outlet pipes 605 penetrate through the top of the heating box 601, they can be in contact connection with the bottoms of the air outlet holes 505 to realize simultaneous heating of the plurality of thermos cups 7 in each row; a return air channel opening 606 is opened on the top of the heating box 601. The return air channel opening 606 is arranged around the outside of the air outlet pipes 605 and can be in contact connection with the bottom of the return air hole 506. The top openings of the air outlet pipes 605 penetrate through the top of the heating box 601 and are at the same height as the top of the heating box 601, so that there is no large height difference between the top openings of the air outlet pipes 605 and the return air channel opening 606. In a preferred embodiment, there is no height difference between the two. The top of the air outlet pipe 605 is in contact connection with the bottom of the air outlet hole 505 moved to this position, and can send hot air into the thermos cup 7 through the air outlet hole 505. The return air channel opening 606 is in contact connection with the return air hole 506. The hot air in the thermos cup 7 will enter the return air channel opening 606 through the return air hole 506 after circulation and finally enter the heating box 601 to be reheated and participate in the next cycle; in order to avoid small wind force, the return air channel opening 606 and the return air hole 506 are not in sealed contact connection, and there is a gap between the two. Therefore, under the suction of the heating circulation fan 604, in addition to the hot air in the thermos cup 7 entering the return air channel opening 606 through the return air hole 506 after circulation, part of the external air will also enter the heating box 601 through the return air channel opening 606, be heated and then enter the heating circulation fan 604.

[0026] The inlet temperature measuring mechanism 3 of this embodiment includes an inlet temperature measuring frame 301 fixed to one end of the top of the frame 1. Vertical lifting sliders 8 are provided on the inner sides of the two side walls of the inlet temperature measuring frame 301. A slider is provided on the lifting slider 8, and the slider is connected to a slider driving mechanism. The slider driving mechanism is a driving motor. In one embodiment, the slider driving mechanism is a nut-screw pair. The screw is vertically arranged and connected to a screw motor. The nut is arranged on the screw and connected to the slider. The screw motor drives the screw to rotate, and the nut drives the slider to move up and down. In other embodiments, the slider driving mechanism can also use a hydraulic cylinder or an oil cylinder to drive the slider to move up and down by means of a telescopic rod. A well-known clamping plate parallel cylinder 9 is provided on the slider. The clamping plate parallel cylinder 9 is connected to two symmetrically arranged sensor clamping plates 10. An arc-shaped clamping groove is opened on the inner side of the sensor clamping plate 10. The clamping plate parallel cylinder 9 can drive the two sensor clamping plates 10 to move towards or away from each other. When the two clamping plate parallel cylinders 9 move towards each other, the arc-shaped clamping grooves corresponding to the two clamping plates can be clamped at the side wall of the thermos cup 7, so as to fixedly clamp the thermos cup 7. A plurality of sensor contacts 11 are provided at different positions of the arc-shaped clamping groove. Thus, the plurality of sensor contacts 11 can detect the temperatures at different positions of the side wall of the thermos cup 7 in a contact manner. Through the detection of multiple points, the detection accuracy is improved. The sensor contacts 11 adopt contact temperature sensors. After contacting the outer side wall of the thermos cup 7, they can measure the temperature of its outer side wall.

[0027] The temperature measuring mechanism 4 at the outlet in this embodiment has the same principle as the temperature measuring mechanism 3 at the inlet. The difference is that the temperature measuring mechanism 4 at the outlet further includes an outlet transfer slide 401 disposed at one end of the top of the frame 1 away from the inlet temperature measuring frame 301. The outlet transfer slide 401 is disposed on both sides of the conveying chain group 5 and is arranged along the length direction of the frame 1. The end of the outlet transfer slide 401 is located above the temporary storage table; a pedestal is slidably provided on the outlet transfer slide 401. The pedestal is driven by a horizontal cylinder, a hydraulic cylinder or a lead screw nut pair and can move horizontally. An outlet temperature measuring frame 402 is fixedly provided on the pedestal; lifting slides 8 arranged vertically are provided on the inner sides of the two side walls of the outlet temperature measuring frame 402. Sliders are provided on the lifting slides 8, and the sliders are connected with slider driving mechanisms; a clamping plate parallel cylinder 9 is provided on the slider. The clamping plate parallel cylinder 9 is connected with two symmetrically arranged sensor clamping plates 10. An arc-shaped clamping groove is provided inside the sensor clamping plates 10. The clamping plate parallel cylinder 9 can drive the two sensor clamping plates 10 to move towards or away from each other. When the two clamping plate parallel cylinders 9 move towards each other, the arc-shaped clamping groove can clamp the side wall of the heat-insulating cup 7. A sensor contact 11 is provided at the arc-shaped clamping groove. The sensor contact 11 is the contact of the temperature sensor. The sensor contact 11 can detect the temperature of the side wall of the heat-insulating cup 7. When the heated heat-insulating cup 7 moves to a position close to the outlet transfer slide 401, the pedestal drives the outlet temperature measuring frame 402 to move to the position of the heat-insulating cup 7, clamps the heated heat-insulating cup 7, and then moves it away from the mounting hole position 502 and moves to a position above the temporary storage table. At this time, secondary temperature measurement starts. After the temperature measurement is completed, the clamped heat-insulating cup 7 can be placed on the temporary storage table.

[0028] In order to better distinguish between qualified good products and unqualified defective products, in a preferred embodiment, a marking actuator 12 is provided on one of the sensor clamping plates 10 of the outlet temperature measuring mechanism 4. The marking actuator 12 includes a telescopic cylinder fixed outside the arc-shaped clamping groove. The end of the cylinder rod of the telescopic cylinder is connected with a marking rod. A marking pattern is engraved at the end of the marking rod away from the telescopic cylinder. Pigment is coated at the marking pattern. The telescopic cylinder is connected with the control end. The two temperature measurement data are input into a mature software at the control end for comparison and analysis. When the control end detects a defective product, it can control the corresponding telescopic cylinder to extend. The control process adopts a mature numerical control method. Further, the telescopic cylinder can drive the marking rod to print the marking pattern on the side wall of the unqualified heat-insulating cup 7, so that an unqualified pattern is printed on the side wall of the unqualified heat-insulating cup 7, which is convenient for subsequent distinction.

[0029] When the present invention works, the above workpiece positioning baffle 2 is used as a reference to place the thermos cup 7 to be measured; after placement, using the mature control program at the control end, the conveying chain group 5 advances one beat to reach the initial measurement inlet temperature measuring mechanism 3 position. The slider of the inlet temperature measuring mechanism 3 descends to the set height, and the sensor clamping plate 10 clamps the thermos cup 7 inward under the action of the clamping plate parallel cylinder 9, so that the contact head of the temperature sensor tightly contacts the outer wall of the thermos cup 7, collects and stores the initial temperature data, then the clamping plate parallel cylinder 9 releases, the slider rises and resets, waiting for the next row of products; the products after the initial temperature measurement reach the heating position and start heating. The heating process is that the electric heating tube 603 heats the air, the heating circulation fan 604 blows the hot air into the air outlet box 602, and then blows out through the air outlet pipe 605 and enters the inside of the thermos cup 7. When the inside of the thermos cup 7 is full and overflows, it enters the return air hole 506 and then enters the return air channel port 606, and then enters the heating box 601, and is reheated by the electric heating tube 603 again and circulates again, so that the inside of the thermos cup 7 continuously remains full of hot air reaching the set temperature, and is continuously heated six times. Figure 6 The arrow in Figure 6 indicates the schematic of the hot air circulation flow state. After six times of heating, there are three natural static positions with or without interference. At this time, the conveying chain group 5 is stationary, simulating the process that the thermos cup 7 is filled with hot water for three minutes and the heat is naturally conducted to the outer shell of the thermos cup 7.

[0030] After the static time is over, the thermos cup 7 enters the secondary temperature measurement position, that is, the outlet temperature measurement position. The slider of the outlet temperature measuring mechanism 4 descends to the set height, the clamping plate parallel cylinder 9 works, and the pushing and installing sensor contact head 11 tightly contacts the outer wall of the thermos cup 7, collects and stores the temperature data of the secondary temperature measurement. Then the clamping plate parallel cylinder 9 does not release, the slider drives the clamped thermos cup 7 to rise to the set transfer height, and the outlet transfer slide 401 works, so that the outlet temperature measuring mechanism 4 drives the thermos cup 7 as a whole to move horizontally, and transfers the whole row of thermos cups 7 to the next process conveying line. In this embodiment, it is transferred to the temporary storage table at the end of the rack 1. When the outlet temperature measuring mechanism 4 moves the product to the designated position, the data processor at the control end processes the data collected from the previous and subsequent temperature measurements, determines whether each row of corresponding multiple thermos cups 7 is qualified, and gives an instruction to the marking actuator 12. For the unqualified thermos cups 7, the corresponding marking actuator 12 acts to label them with unqualified labels. Similarly, the qualified products are not marked. When the marking is over, the whole temperature measurement process is completed. At this time, the clamping plate parallel cylinder 9 in the outlet temperature measuring mechanism 4 releases, the slider rises and resets, and at the same time the outlet transfer slide 401 returns to the original position, waiting for the next process, and so on in a cycle.

[0031] In the present invention, specific examples are used to illustrate the principles and implementation manners of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention; at the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manners and application scopes. In summary, the content of this specification should not be construed as a limitation on the present invention.
