Description

Technical Field

[0001] The present invention relates to the technical field of ointment fluidity detection, and specifically to a consistency detection device for the production of pain-relieving ointments. Background Art

[0002] Pain-relieving ointments are generally applied on patches. When in use, the patches are adhered to the skin around the painful area, so that the ointment can continuously contact the skin of the painful area. To ensure the effect of the ointment, the consistency of the ointment must be set within a reasonable range. If the consistency is too high or too low, it will affect the application effect of the ointment on the patch. Therefore, during the production of the ointment, it is necessary to detect the consistency of the ointment.

[0003] Currently, there are already some devices for detecting the consistency of ointments. For example, a device for detecting the consistency of traditional Chinese medicine ointments in the production disclosed in a Chinese utility model with the publication number CN218382244U includes a conveying mechanism, a storage tube, a consistency detector, and a discharge tube. Among them, the conveying mechanism includes a conveying hose, a flexible auger, a driving motor, and an output tube. The conveying hose is sleeved outside the flexible auger, and the driving motor is fixed at the top of the conveying hose. Another example is a viscosity detection device disclosed in a Chinese utility model patent with the publication number CN220084643U, which includes a detection tube. The detection tube includes a lower half tube, an upper half tube, and a bearing hopper. Thread grooves are provided at the same ends of the lower half tube and the upper half tube. A threaded ring is installed on the bearing hopper, and the threaded ring is threadedly connected to the lower half tube and the upper half tube through the thread grooves. A slot is provided on the lower half tube, and a T-shaped rod is installed on the upper half tube. The T-shaped rod is movably inserted into the lower half tube through the slot. A support structure for supporting the detection tube is provided on the outside of the detection tube, and a rubber sheet is installed on the lower half tube through the slot.

[0004] The detection devices in the prior art, including the above patents, can only detect the consistency of the ointment after a certain amount of ointment production is completed, but cannot detect the ointment on the production line in real time. As a result, the operator cannot collect and process the ointment with consistency problems on the production line in a timely manner. Once the consistency of the ointment is detected to be defective later, all the ointment in a certain amount has to be reprocessed, which will undoubtedly lead to a relatively high cost and low efficiency for subsequent reprocessing. Based on this, how to detect the ointment on the production line in real time so that the operator can collect the ointment with defective consistency in a timely manner is a problem that needs to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of the present invention is to provide a consistency detection device for the production of pain-relieving ointments to solve the above deficiencies in the prior art.

[0006] To achieve the above object, the present invention provides the following technical solution: A device for detecting the consistency of a pain-relieving ointment during production, including a detection platform, on which two baffle plates are fixedly installed. A conveyor belt is arranged between the two baffle plates, and both sides of the conveyor belt are in contact with the baffle plates; A horizontal mounting tube is rotatably installed on the detection platform through a bracket, and a torsion spring is arranged between the mounting tube and the bracket; A number of mounting rings are evenly installed on the mounting tube, and a baffle strip in contact with the ointment is fixedly installed on the mounting ring. A conductive rod is also fixedly installed on the mounting ring through an insulating rod; An arc-shaped guide rail is fixedly installed on the detection platform, and two detection components are installed at the position corresponding to each mounting ring on the arc-shaped guide rail. The detection component includes a power supply box slidably matched with the arc-shaped guide rail, an indicator light is arranged on the power supply box, and conductive connectors are arranged at the positions corresponding to both ends of the conductive rod on the power supply box.

[0007] When the conductive connector is in contact with the conductive rod, the power supply, the indicator light, the conductive connector and the conductive rod in the power supply box form a series circuit.

[0008] As a preferred technical solution of the present invention, a scraping blade is slidably installed on the baffle strip along its length direction, the scraping blade is in contact with the surface of the baffle strip, and a driving component for driving the scraping blade to reciprocate is also arranged on the baffle strip.

[0009] As a preferred technical solution of the present invention, the driving component includes a driving shaft rotatably installed on the side wall of the baffle strip. The number of driving shafts is two and they are symmetrically arranged. A driving arm is fixedly installed on the driving shaft; One end of the driving arm is hinged with a driven arm, and one end of the driven arm is rotatably matched with the scraping blade through a pin shaft.

[0010] As a preferred technical solution of the present invention, a round wheel is fixedly installed on the driving shaft, and a number of baffle pieces are evenly fixedly installed on the circumferential surface of the round wheel along its circumferential direction.

[0014] In the above technical solution, a device for detecting the consistency of a pain-relieving ointment provided by the present invention is provided with a retaining bar above the conveyor belt. When the conveyor belt conveys the ointment, the retaining bar is offset at a certain angle due to the acting force of the ointment on the retaining bar; if the consistency of the ointment is low, the acting force between it and the retaining bar is small, and the offset angle of the retaining bar is small; if the consistency of the ointment is high, the acting force between it and the retaining bar is large, and the offset angle of the retaining bar is also large; when the consistency of the ointment is lower than the minimum value of the established range, the indicator light of one of the detection components will light up and give a prompt, and when the consistency of the ointment is higher than the maximum value of the established range, the indicator light of the other detection component will light up and give a prompt. By observing the indicator light, the operator can know whether the consistency of the ointment on the conveyor belt is qualified and collect the ointment with defective consistency in time.

Detailed implementation manner

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] As Figure 1 shown, this embodiment provides a viscosity detection device for the production of pain-relieving ointment, including a detection platform 1. Two vertical baffles 2 are fixedly installed on the detection platform 1. The two baffles 2 are parallel to each other and a conveyor belt 3 is arranged between the two baffles 2. The conveyor belt 3 is driven by a pulley and conveys at a constant speed. The two sides of the conveyor belt 3 are in contact with the baffles 2. The detection platform 1 supports the inner side of the conveyor belt 3, so that the upper surface of the conveyor belt 3 remains horizontal. During the production process, the conveyor belt 3 conveys the ointment, and the baffles 2 block the ointment to ensure that the ointment is always on the conveyor belt 3 during the detection process.

[0027] As Figure 1As shown, a horizontal mounting pipe 5 is rotatably mounted on the detection platform 1 through a bracket 4. The axis of the mounting pipe 5 is perpendicular to the conveying direction of the conveyor belt 3. A torsion spring is provided between the mounting pipe 5 and the bracket 4. A number of mounting rings 6 are evenly mounted on the mounting pipe 5, and a stop bar 7 located between the two baffle plates 2 is fixedly mounted on the mounting ring 6. In the initial state, the stop bar 7 does not contact the ointment, and both the stop bar 7 and the insulating rod are in the vertical state. During the conveying process of the ointment by the conveyor belt 3, the ointment contacts the stop bar 7 and overcomes the acting force of the torsion spring to push the stop bar 7 to rotate. It should be noted that under the same other conditions, that is, when the conveying speed of the ointment is the same and the thickness of the ointment on the conveyor belt 3 always remains the same; the higher the consistency of the ointment, the greater the acting force between it and the stop bar 7, and the greater the rotation angle of the stop bar 7. The lower the consistency of the ointment, the smaller the acting force between it and the stop bar 7, and the smaller the rotation angle of the stop bar 7. Thus, when the detection device in this embodiment is actually used, it needs to be debugged in advance, that is, first determine the range of the ointment consistency, then prefabricate the ointment with the minimum consistency for conveying to mark the rotation angle of the stop bar 7 in this state, and then prefabricate the ointment with the maximum consistency for conveying to mark the rotation angle of the stop bar 7 in this state. During the subsequent production process, as long as the rotation angle of the stop bar 7 is within this range of the two angles, the consistency of the ointment meets the requirements. If the rotation angle of the stop bar 7 exceeds this range, the consistency of the ointment does not meet the requirements.

[0028] As Figure 3 , Figure 4 , Figure 5 and Figure 7As shown in the figure, a conductive rod 8 is also fixedly installed on the mounting ring 6 through an insulating rod. When the baffle 7 rotates, the mounting ring 6 and the conductive rod 8 also rotate synchronously, and the baffle 7 and the conductive rod 8 rotate by the same angle; an arc-shaped guide rail 9 is fixedly installed on the detection platform 1, and the virtual axis of the arc-shaped guide rail 9 coincides with the axis of the mounting tube 5; two detection components 10 are installed at the positions corresponding to each conductive rod 8 on the arc-shaped guide rail 9. The detection component 10 includes a power supply box 1001 slidably matched with the arc-shaped guide rail 9. A clamping jaw is arranged on the power supply box 1001. By cooperating the clamping jaw with the arc-shaped guide rail 9, the power supply box 1001 is kept stationary relative to the arc-shaped guide rail 9. The specific structure of the clamping jaw is the prior art and will not be elaborated here; a power supply is fixedly installed in the power supply box 1001. An indicator light 1002 is arranged on the power supply box 1001. When the indicator light 1002 is powered on, it will light up and emit a prompt sound. Conductive connectors 1003 are arranged at the positions corresponding to both ends of the conductive rod 8 on the power supply box 1001; when the conductive connector 1003 contacts the conductive rod 8, the power supply, the indicator light 1002, the conductive connector 1003 and the conductive rod 8 in the power supply box 1001 form a series circuit. In this way, when debugging the equipment, the operator only needs to adjust the two power supply boxes 1001 corresponding to the conductive rod 8 to the two extreme positions on the arc-shaped guide rail 9. In one extreme position, when the minimum consistency ointment is conveyed, the rotation angle of the baffle 7 and the conductive rod 8 just makes the conductive rod 8 contact the conductive connector 1003; in the other extreme position, when the maximum consistency ointment is conveyed, the rotation angle of the baffle 7 and the conductive rod 8 just makes the conductive rod 8 contact the conductive connector 1003; to Figure 5 illustrate, in actual production, in the initial state, the conductive rod 8 does not contact the conductive connector 1003, and both indicator lights 1002 are in the power-off and extinguished state; when the left indicator light 1002 lights up and emits a prompt sound, it means that the consistency of the ointment in contact with the baffle 7 at this moment reaches the lowest value within the reasonable range. When the right indicator light 1002 lights up and emits a prompt sound, it means that the consistency of the ointment in contact with the baffle 7 at this moment reaches the highest value within the reasonable range; the operator can collect the ointment on the conveyor belt 3 in time and return it to the upstream production line for reprocessing.

[0029] In summary, in this embodiment, it is possible to realize real-time detection of the consistency of the ointment on the conveyor belt 3 during the production process of the ointment, helping the operator to timely understand whether the consistency of the ointment is within the set range. It should be noted that due to the uncertainty of the force between the ointment and the baffle 7, even when the ointment with a constant consistency is conveyed uniformly on the conveyor belt 3, the offset angle of the baffle 7 also changes slightly. However, because the accuracy requirement for the detection of the ointment consistency is not high, even if there is an error, it will not have an obvious impact on the overall quality of the ointment consistency. Therefore, it does not affect the detection accuracy.

[0030] As Figure 2 and Figure 3As shown, a wiper blade 11 is slidably mounted on the baffle 7 along its length direction, and the wiper blade 11 is in contact with the surface of the baffle 7. A driving assembly 12 for driving the wiper blade 11 to reciprocate is provided on each baffle 7; in order to prevent the ointment from sticking to the surface of the baffle 7 and increasing the weight of the baffle 7, resulting in detection errors, it is necessary to scrape the ointment on the surface of the baffle 7 with the wiper blade 11; specifically, the driving assembly 12 includes a driving shaft 1201 rotatably mounted on the side wall of the baffle 7. The driving shaft 1201 is parallel to the axis of the mounting tube 5. The number of driving shafts 1201 is two and they are symmetrically arranged. A driving arm 1202 is fixedly mounted on each driving shaft 1201. One end of the driving arm 1202 is hinged with a driven arm 1203, and one end of the driven arm 1203 is rotatably matched with the wiper blade 11 through a pin shaft; a round wheel 1204 coaxial with the driving shaft 1201 is fixedly mounted on the driving shaft 1201. A plurality of baffle plates 1205 are uniformly fixedly mounted on the circumferential surface of the round wheel 1204 along its circumferential direction. In the actual production process, a lower part of the round wheel 1204 is located in the ointment. When the ointment is conveyed, it will contact the baffle plates 1205 and drive the baffle plates 1205 and the round wheel 1204 to rotate. The round wheel 1204 drives the driving shaft 1201 and the driving arm 1202 to rotate. When the driving arm 1202 rotates, it drives the wiper blade 11 to reciprocate along the baffle 7 through the driven arm 1203, and scrapes the surface of the baffle 7. To sum up, in this embodiment, the power is provided by the acting force between the conveyed ointment and the baffle plates 1205, and the wiper blade 11 can reciprocate along the baffle 7 without providing an additional power source, which greatly reduces the manufacturing cost of the device.

[0031] As Figure 5 , Figure 6 and Figure 7 shown, two marking components 13 are installed at the positions corresponding to each conductive rod 8 on the bracket 4. The marking components 13 are connected in parallel with the corresponding detection components 10 through wires; the marking components 13 include storage cylinders 1301. Both storage cylinders 1301 store medicinal powders, and the medicinal powders stored in the two storage cylinders 1301 have different colors. The medicinal powder is one of the raw materials of the ointment, that is, the medicinal powder will not affect the medicinal properties of the ointment after contacting the ointment; a discharge hole 1302 is opened at the bottom end of the storage cylinder 1301, and a motor 1303 is installed at the top of the storage cylinder 1301. A spiral blade 1304 matched with the discharge hole 1302 is fixedly mounted on the output shaft of the motor 1303; the motor 1303 is connected in parallel with the indicator light 1002 through a wire.

[0032] Specifically, during the production process, if the consistency of the ointment in contact with the retaining bar 7 reaches the lowest value within the reasonable range, the conductive rod 8 will come into contact with the corresponding conductive joint 1003. At this time, the motor 1303 and the indicator light 1002 are in a parallel state, and the entire circuit is in a conductive state. The corresponding power supply will supply power to the motor 1303 and the indicator light 1002. While the indicator light 1002 is lit, the motor 1303 also starts to operate. When the motor 1303 operates, it drives the spiral blade 1304 to rotate. The spiral blade 1304 conveys the powder in the storage barrel 1301 downward through the discharge hole 1302. The powder leaving the discharge hole 1302 falls onto the upper surface of the ointment to mark the ointment. The consistency of the ointment covered by this colored powder is relatively low. Similarly, if the consistency of the ointment in contact with the retaining bar 7 reaches the maximum value within the reasonable range, the conductive rod 8 will come into contact with the corresponding conductive joint 1003. At this time, the motor 1303 and the indicator light 1002 are in a parallel state, and the entire circuit is in a conductive state. The corresponding power supply will supply power to the motor 1303 and the indicator light 1002. While the indicator light 1002 is lit, the motor 1303 also starts to operate. When the motor 1303 operates, it drives the spiral blade 1304 to rotate. The spiral blade 1304 conveys the powder in the storage barrel 1301 downward through the discharge hole 1302. The powder leaving the discharge hole 1302 falls onto the upper surface of the ointment to mark the ointment. The consistency of the ointment covered by this colored powder is relatively high. In this way, during the subsequent reprocessing, the operator only needs to observe the color of the powder on the surface of the ointment to determine whether the consistency of this part of the ointment is too high or too low, so as to accurately classify and collect the ointment.

[0033] As Figure 3 shown, a material guiding plate 14 is fixedly installed between the two baffle plates 2. The material guiding plate 14 includes a horizontal section 1401 close to the retaining bar 7 and an inclined section 1402 far from the retaining bar 7. The ointment on the conveyor belt 3 contacts the inclined section 1402 and the horizontal section 1401 successively before contacting the retaining bar 7 to ensure that the thickness of the ointment in contact with the retaining bar 7 is uniform and improve the accuracy of detection.

[0034] It should be noted that the consistency detection device for the production of pain-relieving ointment provided in this embodiment can detect different types of ointments, that is, under the condition that the reasonable ranges of the ointment consistency are different, this device can perform detection, and only the position of the detection component 10 on the arc-shaped guide rail 9 needs to be adjusted. And a positioning piece is provided at the end of the installation pipe 5. Two limit pieces corresponding to the position of the positioning piece are slidably installed on the bracket 4 along the circumferential direction of the installation pipe 5. The limit pieces can be fastened by bolts to achieve being stationary at any position on the circular path. By adjusting the positions of the two limit pieces, the rotation angle of the positioning piece can be restricted, so as to restrict the rotation angles of the installation pipe 5, the retaining bar 7 and the conductive rod 8, so that the installation pipe 5, the retaining bar 7 and the conductive rod 8 can only rotate within the angular range corresponding to the two detection components 10.

[0035] Only some exemplary embodiments of the present invention have been described above by way of illustration. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
