[0002] A foot bath pack is a foot bath tool made with traditional Chinese herbal medicine formulas. It is usually composed of a variety of Chinese herbal medicine formulas. Different herbs can be selected for soaking according to different needs to achieve different effects. Generally speaking, foot bath packs are sold in the form of powder and small bags. Users only need to put the foot bath pack into the foot bath basin and then add warm water to soak their feet.

[0003] During the production of foot bath packs, sealing failures often occur, causing the medicinal materials inside the pack to leak out and rendering it unusable. Currently, foot bath packs are generally inspected manually, which is inefficient, time-consuming, and labor-intensive. It is not easy to accurately and quickly detect foot bath packs with failed sealing. Furthermore, during production, foot bath packs may also have missing fillers or insufficient filler, all of which affect product quality and hinder the efficient and high-quality production of foot bath packs.

A support frame is fixedly connected to the side of the conveyor frame away from the guide frame, and a weighing detection mechanism for weighing and classifying the foot bath packs is provided at the top of the support frame.

[0006] Preferably, the two guide frames are symmetrically arranged with the vertical center line of the conveyor frame as the axis of symmetry, and the distance between the closest parts of the two guide frames is greater than the length of the longest side of the foot bath pack. The weighing and detection mechanism corresponds to the middle of the conveyor frame.

[0008] Preferably, the first pushing mechanism includes a first electric push rod and a first pushing plate. The fixed rod of the first electric push rod is horizontally fixedly installed at the bottom of the side of the first bracket. The first pushing plate is fixedly connected to the end of the movable rod of the first electric push rod. The second pushing mechanism includes a second electric push rod and a second pushing plate. The fixed rod of the second electric push rod is horizontally fixedly installed at the bottom of the second bracket on the same side as the first pushing mechanism. The second pushing plate is fixedly installed at the end of the movable rod of the second electric push rod. Both the first pushing plate and the second pushing plate are attached to the upper surface of the conveyor frame and can move laterally on its upper surface.

[0009] Preferably, the pressure detection mechanism includes a third electric push rod, a pressure plate, an elastic cover, a pressure sensor, and a second photoelectric sensor.

[0012] This foot bath pack production testing device, through the setup of an infrared thermal imaging detection mechanism, a pressure detection mechanism, and a weighing detection mechanism, enables the infrared thermal imaging detection mechanism to detect the residual temperature distribution characteristics of the sealing area of ​​the foot bath pack to determine whether the sealing of each part of the foot bath pack is tight. This allows the first pushing mechanism to push foot bath packs with failed sealing to one side, while the pressure detection mechanism presses down on the foot bath packs below, detecting whether the foot bath pack contains filler based on the pressure. The second pushing mechanism then pushes foot bath packs without filler to one side. The weighing detection mechanism quickly weighs foot bath packs that have passed both tests, and separates those that meet the weight standards from those that do not, placing them on opposite sides. This device can perform graded testing and screening of foot bath packs, sequentially detecting those with loose seals, those without filler, and those that are too light. This facilitates the rapid detection of various unqualified products, greatly improving the production efficiency and quality of foot bath packs, preventing unqualified products from entering the market, and making it more convenient to use in the production of foot bath packs.

[0019] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figures 1 to 5 The embodiments are described in detail below.

[0020] This embodiment provides a testing device for the production of foot bath packs, as shown in the attached document. Figure 1-5As shown, the conveyor includes a conveyor frame 1, a first support 2, and a second support 3. The conveyor frame 1 is an existing belt conveyor, which is known technology and will not be described in detail here. Both sides of one end of the top of the conveyor frame 1 are fixedly connected to guide frames 4. The two guide frames 4 are symmetrically arranged with the vertical center line of the conveyor frame 1 as the axis of symmetry, and the distance between the closest parts of the two guide frames 4 is greater than the length of the longest side of the foot bath pack. This ensures that the foot bath pack can pass smoothly through the middle of the two guide frames 4, and the two guide frames 4 can limit and guide the flow of the foot bath pack, ensuring that each foot bath pack can be in the middle of the conveyor frame 1, thereby ensuring that each foot bath pack can pass through the multiple detection mechanisms behind it.

[0021] The first support 2 is fixedly connected to the middle of the upper surface of the conveyor frame 1, and an infrared thermal imaging detection mechanism is provided at the middle of its top. The infrared thermal imaging detection mechanism includes an infrared thermal imager 6 and a first photoelectric sensor 7. The infrared thermal imager 6 is fixedly installed at the middle of the top of the first support 2 with the detection direction vertically downward. The first photoelectric sensor 7 is fixedly installed at the middle of the top of the first support 2 near the guide frame 4 with the detection direction vertically downward. The first photoelectric sensor 7 is located in front of the infrared thermal imager 6. After the foot bath pack moves to below the first photoelectric sensor 7, the first photoelectric sensor 7 can monitor the foot bath pack in real time, which is equivalent to the triggering mechanism of the infrared thermal imager 6 and can be controlled by the control unit. The infrared thermal imager takes pictures of the foot bath packs as they pass through. Because the molten material cools slowly, the sealed area, which is qualified and fully molten, will form a relatively uniform temperature field that is slightly higher than the ambient temperature during the cooling process. However, areas with incomplete sealing, leaks, or insufficient sealing strength may have different heat conduction characteristics due to gaps at the seal or other reasons, leading to abnormal residual temperature distribution in the area, such as abrupt temperature gradient changes, local low-temperature areas, or high-temperature areas. Therefore, the residual temperature distribution characteristics of the sealed area within a few seconds to tens of seconds after heat sealing can be used to judge the sealing condition of the foot bath pack, making it easier to detect foot bath packs with failed sealing.

[0022] A first pushing mechanism for pushing foot bath packs is provided on one side of the first support 2. The first pushing mechanism includes a first electric push rod 8 and a first pushing plate 9. The fixed rod of the first electric push rod 8 is horizontally fixedly installed at the bottom of the side of the first support 2. The first pushing plate 9 is fixedly connected to the end of the movable rod of the first electric push rod 8. When the infrared thermal imager 6 detects a foot bath pack with a failed seal, the control unit will immediately control the movable rod of the first electric push rod 8 to extend, so that the first pushing plate 9 pushes the foot bath pack to the side of the upper surface of the conveyor frame 1 away from the first electric push rod 8 and can continue to be conveyed backward under the drive of the conveyor frame 1. The unqualified foot bath packs detected in this part will no longer participate in the subsequent inspection; the foot bath packs with normal seals will continue to be conveyed backward along the middle of the conveyor frame 1.

[0023] The second support 3 is fixedly connected to the upper surface of the conveyor frame 1 on the side away from the guide frame 4, and a pressure detection mechanism for detecting whether there is filling material inside the foot bath pack is provided at the middle of its top. The pressure detection mechanism includes a third electric push rod 12, a pressure plate 13, an elastic cover 14, a pressure sensor 15, and a second photoelectric sensor 16. There are two third electric push rods 12, and the fixed rod parts of the two third electric push rods 12 are vertically fixedly installed on the top of the second support 3. The pressure plate 13 is fixedly connected to the bottom end of the movable rod of the two third electric push rods 12. Multiple pressure sensors 15 are fixedly installed at equal intervals on the lower surface of the pressure plate 13, and the elastic cover 14 is fixedly connected to the pressure plate 16. The lower surface of the second bracket 3 is fitted onto the outside of the pressure sensor 15. The second photoelectric sensor 16 is fixedly installed on the side of the top center of the second bracket 3 near the first bracket 2, with the detection direction vertically downward. The second photoelectric sensor 16 serves as the trigger mechanism for the second electric push rod 12. When the second photoelectric sensor 16 detects that a foot bath pack is passing below, the control unit controls the conveying mechanism at the top of the conveying frame 1 to pause. At the same time, the movable rod of the third electric push rod 12 presses down, pressing the bottom of the elastic cover 14 onto the foot bath pack and covering it. Then it quickly rises. The entire pressing and rising process does not exceed 2 seconds. The conveying frame 1 also pauses briefly and then continues to move, ensuring the stable operation of the entire production line. When the elastic cover 14 is pressed down onto the foot bath pack, if the foot bath pack is normally filled with Chinese herbal medicine filling material, the bulging foot bath pack will push up the lower surface of the elastic cover 14 and make the bottom of the elastic cover 14 press against the pressure sensor 15, so that the pressure sensor 15 can detect the pressure. If the foot bath pack below is missing filling material, the bottom of the elastic cover 14 will not be pushed up, so the pressure sensor 15 will not change. Thus, the pressure sensor 15 can detect whether the current foot bath pack is empty. This part makes it easy to detect foot bath packs that are missing filling material.

[0024] The second support 3 is provided with a second pushing mechanism on the same side as the first pushing mechanism. The second pushing mechanism includes a second electric push rod 10 and a second pushing plate 11. The fixed rod of the second electric push rod 10 is horizontally fixedly installed at the bottom of the second support 3 on the same side as the first pushing mechanism. The second pushing plate 11 is fixedly installed at the end of the movable rod of the second electric push rod 10. The first pushing plate 9 and the second pushing plate 11 are both attached to the upper surface of the conveyor frame 1 and can move laterally on its upper surface. When the pressing detection mechanism detects that the foot bath pack is empty, the control unit will immediately control the movable rod of the second electric push rod 10 to extend, so that the second pushing plate 11 pushes the corresponding empty pack to the side away from the second electric push rod 10, on the same side as the unqualified foot bath pack detected by the infrared thermal imaging detection mechanism, and can continue to move backward with the conveyor frame 1 without participating in the subsequent weighing detection. The foot bath packs that pass the pressing mechanism will continue to move along the middle of the conveyor frame 1 onto the weighing detection mechanism.

[0025] A support frame 5 is fixedly connected to the side of the conveyor frame 1 away from the guide frame 4. The top of the support frame 5 is equipped with a weighing and detection mechanism for weighing and classifying foot bath packs. The weighing and detection mechanism includes a geared motor 17, a rotating frame 18, a horizontal sensor 19, and an electronic weighing instrument 20. The rotating frame 18 is rotatably mounted on the top of the support frame 5, and its rotating shaft is connected to the output end of the geared motor 17 via a spline. The geared motor 17 is fixedly mounted on the top of the support frame 5 on the side away from the conveyor frame 1. The geared motor 17 can drive the rotating frame 18 to rotate, thereby adjusting the tilt angle of the electronic weighing instrument 20. The horizontal sensor 19 is fixedly mounted in the middle of the lower surface of the rotating frame 18. The horizontal sensor 19 can monitor the tilt angle of the electronic weighing instrument 20 in real time, thereby allowing the control unit to control the geared motor 17 to adjust the electronic weighing instrument 20 to the required tilt angle or horizontal state. The electronic weighing instrument 20 is fixedly mounted on the upper surface of the rotating frame 18 and corresponds to the middle of the conveyor frame 1. The top of the electronic weighing instrument 20... Slightly below the upper surface of the conveyor frame 1; the foot bath packs that have passed the test by the pressure detection mechanism move to the electronic weighing instrument 20 under the inertia of the conveyor frame 1. The electronic weighing instrument 20 can detect the foot bath packs in real time. When the weight of the foot bath pack is not within the set qualified weight range, the control unit will control the reduction motor 17 to drive the rotating frame 18 to rotate clockwise by 45-60 degrees, thereby tilting the foot bath packs above it onto the same side as the unqualified foot bath packs detected by the infrared thermal imaging detection mechanism and the pressure detection mechanism. The operator can place a collection container at the end of the conveyor frame 1 on this side to collect the unqualified foot bath packs detected by each detection mechanism. When the weight of the foot bath pack is within the set qualified weight range, the control unit controls the reduction motor 17 to drive the rotating frame 18 to rotate counterclockwise by 45-60 degrees, thereby transferring the qualified foot bath packs to the other side. The operator can set up a qualified product collection container on this side to collect the qualified foot bath packs.

[0026] The conveyor frame 1, infrared thermal imager 6, first photoelectric sensor 7, first electric push rod 8, second electric push rod 10, third electric push rod 12, pressure sensor 15, second photoelectric sensor 16, geared motor 17, level sensor 19 and electronic weighing instrument 20 are all connected to the external control unit and are all electrically connected to the external circuit through wires.

[0027] In summary, the operating steps of this testing device for foot bath pack production are as follows:

[0028] 1. After heat sealing, the foot bath packs enter the conveyor frame 1 in sequence. The guide frame 4 can adjust the foot bath packs to the middle of the conveyor frame 1. When the foot bath packs move to the bottom of the first photoelectric sensor 7, the control unit controls the infrared thermal imager 6 to take pictures of the foot bath packs that have passed by. Based on the temperature characteristics at the sealing point, the foot bath packs that have failed to seal are detected, and the unqualified foot bath packs are picked out by the first pushing mechanism.

[0029] 2. The foot bath pack with normal edge sealing will continue to move backward along the middle of the conveyor frame 1. When the second photoelectric sensor 16 detects that a foot bath pack is passing below, the control unit controls the conveying mechanism at the top of the conveyor frame 1 to stop. At the same time, the movable rod of the third electric push rod 12 presses down, so that the bottom elastic cover 14 presses tightly on the foot bath pack and covers it. Then it rises quickly. According to the detection of the pressure sensor 15, it is determined whether the foot bath pack is missing filler. The foot bath pack with missing filler is picked out by the second pushing mechanism.

[0030] 3. Foot bath packs that have passed the pressure testing mechanism are moved to the electronic weighing instrument 20 by the inertia of the conveyor frame 1. When the electronic weighing instrument 20 detects that the weight of the foot bath pack is not within the set acceptable weight range, the control unit controls the reduction motor 17 to drive the rotating frame 18 to rotate clockwise by 45-60 degrees, thereby tilting the foot bath pack on top of it to the same side as the unacceptable foot bath packs detected by the infrared thermal imaging testing mechanism and the pressure testing mechanism. When the weight of the foot bath pack is within the set acceptable weight range, the control unit controls the reduction motor 17 to drive the rotating frame 18 to rotate counterclockwise by 45-60 degrees, thereby transferring the qualified foot bath packs to the other side, making it easier to detect qualified foot bath packs.

[0031] The above description is only for illustrating the present utility model. It should be understood that the present utility model is not limited to the above embodiments, and various modifications that conform to the concept of the present utility model are within the protection scope of the present utility model.
