Description

Technical Field

[0001] The present application relates to the technical field of honeysuckle dew production, and in particular to a sugar-free honeysuckle dew and a preparation device and method thereof. Background Art

[0002] Honeysuckle dew is a traditional Chinese medicine preparation with the effects of clearing away heat, detoxifying, and evacuating wind-heat. It is mainly made from honeysuckle as a raw material, and its active ingredients are extracted by steam distillation or soaking. It usually exists in liquid form, which is easy to take orally and absorb.

[0003] In the process of preparing honeysuckle dew, one of the steps is to fill the honeysuckle dew liquid into a glass bottle. The equipment used in this step is a filling machine, which usually includes a liquid storage tank, a filling head and a capping device. When the glass bottle is transported to the filling machine, the filling head is located directly above the glass bottle, and the filling head fills the liquid in the liquid storage tank into the glass bottle, and then the capping device tightens the bottle cap on the glass bottle, thereby completing the filling of the honeysuckle dew.

[0004] However, in the above technology, when the screw-capping device screws the bottle cap onto the glass bottle, the bottle cap may not be tightly connected to the glass bottle, so there will be a gap between the glass bottles, which may easily cause the honeysuckle dew liquid in the glass bottle to leak, or external air to enter the bottle, causing the honeysuckle dew to deteriorate. Summary of the invention

[0005] The purpose of this application is to provide a sugar-free honeysuckle dew and its preparation equipment and method, which can ensure the sealing between the glass bottle and the lid, thereby minimizing the leakage or deterioration of the liquid in the bottle, thereby improving the production quality of the honeysuckle dew.

[0006] In the first aspect, the present application provides a preparation device for a sugar-free honeysuckle dew, comprising a filling machine: The filling machine includes a filling device and a capping device. The filling device is used to fill honeysuckle dew liquid into a glass bottle, and the capping device is used to tighten the bottle cap on the glass bottle. The filling machine is also provided with a detection mechanism, which is used to detect the connection sealing between the bottle cap and the bottle body.

[0007] Optionally, the detection mechanism includes a bracket mounted on the filling machine. A detection disk is slidably arranged on the bracket in the vertical direction. The detection disk is located directly above the bottle cap. A driving member for driving the detection disk to slide is also arranged on the bracket. Two detection needles are slidably arranged on the detection disk in the vertical direction. The two detection needles are located on the same surface and are relatively arranged on both sides of the axis of the detection disk. The two detection needles are exactly the same and have the same initial height position. A detection column is coaxially arranged at the upper end of the detection disk. A detection block is slidably arranged on the detection column. A balance rod is rotatably arranged on the detection block. The center point of the balance rod is rotatably connected to the detection block. The tops of the two detection needles are slidably abutted against the bottom of the balance rod. Two groups of laser sensors are arranged on the detection disk. The two groups of laser sensors are relatively arranged on both sides of the detection column. The laser emitted by the laser sensor passes through close to the uppermost end of the balance rod. Two light receivers corresponding to the laser sensors one by one are arranged on the detection disk.

[0008] Optionally, abutting blocks are arranged on the peripheral walls of the two detection needles, and the abutting blocks are abutted against the upper end surface of the detection disk.

[0009] Optionally, light-transmitting blocks are respectively arranged on both sides of the balance rod. The two light-transmitting blocks correspond to the two laser sensors one by one. The light-transmitting blocks are provided with multiple light-transmitting layers in the vertical direction, and the light transmittance of each light-transmitting layer gradually decreases from top to bottom. The laser emitted by the laser sensor passes through close to the uppermost end of the light-transmitting block.

[0010] Optionally, a rotating member for driving the detection disk to rotate around its own axis is also arranged on the bracket.

[0011] Optionally, a reset member is arranged on the bracket, and the reset member can make both sides of the balance rod return to the same height.

[0012] Optionally, the reset member is set as a reset block. The reset block is horizontally installed on the bracket, and a reset groove for resetting the balance rod is also opened at the lower end of the reset block. The peripheral wall of the upper part of the balance rod is abutted against the groove wall of the reset groove.

[0013] In a second aspect, a preparation method of a sugar-free honeysuckle dew provided by the present application includes the following steps: S1: Raw material treatment, cleaning the raw materials of the honeysuckle dew and draining them, and removing impurities; S2: Extracting the original liquid, distilling the raw materials by steam distillation to obtain an extract; S3: Concentrating and blending, concentrating the extract by a concentration technique to obtain a concentrated liquid with a higher purity, and adding a certain amount of sugar substitute to the concentrated liquid for blending to obtain the honeysuckle dew liquid; S4: Sterilization and filling. The honeysuckle flower dew liquid is sterilized by high-temperature short-time sterilization, and then the honeysuckle flower dew liquid is filled into glass bottles in a sterile workshop.

[0014] Thirdly, a sugar-free honeysuckle flower dew provided by the present application is prepared based on the above steps and includes the following mass percentages: Honeysuckle extract 45%-55%, sweetener 3%-5%, acidulant 0.08%-0.2%, stabilizer 0.08%-0.2%, and the balance is purified water; the sweetener is low-sugar erythritol.

[0015] In summary, the present application includes at least one of the following beneficial technical effects: 1. The sweetener used in the honeysuckle flower dew in the present application is low-sugar erythritol. The sweetness of erythritol is not lower than that of granulated sugar, but the sugar content of erythritol is much lower than that of granulated sugar. Therefore, the honeysuckle flower dew in the present application is still suitable for diabetic patients, and for normal people, it can also greatly reduce the risk of suffering from diabetes. Therefore, it has a better taste and less harm to the human body at the same time. 2. The driving member in the present application can drive the detection disk to move down a fixed distance. If the bottle cap is normally screwed onto the bottle body, then the lower ends of the two detection needles that move down with the detection disk just abut against the upper end surface of the bottle cap. Therefore, the detection needles will not move upward relative to the detection disk, and the balance bar that abuts against the upper ends of the detection needles will not move upward either. Therefore, the balance bar will not block the laser emitted by the laser sensor, and the two light receivers can continuously receive the optical signal, indicating that the bottle cap is normally screwed onto the bottle body. Similarly, if the light receiver does not receive the optical signal, it means that the bottle cap is not at the normal height and the bottle cap is not tightened onto the bottle body. In addition, if one of the light receivers receives the optical signal and the other light receiver does not receive the optical signal, it means that the bottle cap is in an inclined state, and there will still be a large gap between the bottle cap in the inclined state and the bottle body. Therefore, as long as at least one of the light receivers does not receive the optical signal, the screening component on the production line will pick out the glass bottles with the bottle caps not tightened for re-tightening.

[0016] 3. Since the upper end surface of the bottle cap is circular, it can be inclined in a 360-degree direction. Because of the setting of the rotating member, the detection disk can be driven to rotate, thereby driving the two detection needles to slide on the bottle cap. Since the two detection needles are relatively distributed on both sides of the axis of the bottle cap, during the rotation process, as long as the heights of the two detection needles are inconsistent, it can be immediately shown by the light receiver, indicating that there is a height difference on the upper end surface of the bottle cap, thus indicating that the bottle cap is in an inclined state. Generally speaking, the setting of the rotating member can enable the detection mechanism in the present application to detect the bottle cap in multiple directions, greatly improving the detection accuracy of the detection mechanism. 4. When the detection needle detects an untightened bottle cap, the position of the detection needle is not at the original height position. And due to factors such as the friction between the detection needle and the detection disc, the detection needle may not be able to return to the original height position under the action of gravity. Therefore, through the setting of the reset member, the detection needle can be made to return to the original height position after detection, thereby facilitating the accurate detection of the detection needle next time.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The following Figures 1-5 is a further detailed description of the present application in conjunction with Embodiment 1

[0019] A preparation method of sugar-free honeysuckle dew includes the following steps: S1: Raw material treatment, select dry and non-mildewed honeysuckle raw materials, wash the raw materials and drain them, and remove impurities; S2: Extract the original liquid, distill the raw materials by steam distillation method to obtain the extract; S3: Concentration and formulation, concentrate the extract by concentration technology to obtain a concentrated liquid with higher purity, and add a certain amount of artificial sweetener citric acid to the concentrated liquid for formulation, and xanthan pectin can also be added to prevent precipitation, and then obtain the honeysuckle dew liquid; S4: Sterilization and filling. The honeysuckle flower dew liquid is sterilized by high-temperature short-time sterilization, and then the honeysuckle flower dew liquid is filled into glass bottles in a sterile workshop. Example 2

[0020] Refer to Figure 1 and Figure 2 , on one side of the filling machine 1 in this embodiment, a conveyor belt assembly 2 is provided. The conveyor belt assembly 2 transports the glass bottles to be filled one by one to the filling machine 1, and then transports the filled glass bottles to the next station; the filling machine 1 in this embodiment includes a filling device 11 and a capping device 12. The filling device 11 is used to fill the honeysuckle flower dew liquid into the glass bottles, and the capping device 12 is used to screw the bottle cap tightly onto the glass bottle. The filling device 11 and the capping device 12 are both prior arts, so no further details will be given here. A detection mechanism 3 is also provided beside the capping device 12. The detection mechanism 3 is used to detect the connection tightness between the bottle cap and the bottle body 4.

[0021] The detection mechanism 3 in this embodiment includes a bracket 31 and a detection disc 32.

[0022] The bracket 31 is fixedly installed on the machine body. A driving member 33 is provided on the bracket 31. In this embodiment, the driving member 33 is a nut-screw rod assembly (prior art, not described in detail here). When the nut-screw rod assembly drives an object to move, the stability is relatively high. Therefore, the influence on the detection mechanism 3 in the detection process of this application is relatively small. In this embodiment, the nut-screw rod assembly is arranged in the vertical direction, and the nut in the nut-screw rod assembly slides in the vertical direction. The detection disk 32 is fixedly connected to the nut in the nut-screw rod assembly. The detection disk 32 and the bottle cap on the filled glass bottle are coaxially arranged in the vertical direction. Two needle holes 321 are vertically formed on the upper end surface of the detection disk 32. The axes of the two needle holes 321 are perpendicular to the axis of the detection disk 32, and the two needle holes 321 are relatively distributed on both sides of the axis of the detection disk 32. The two needle holes 321 penetrate through the detection disk 32. Detection needles 322 are coaxially and slidably arranged in the two needle holes 321. The peripheral wall of the detection needle 322 is in sliding contact with the inner wall of the needle hole 321. An abutting block 323 is coaxially and fixedly connected to the peripheral wall of the detection needle 322. The lower end surface of the abutting block 323 abuts against the upper end surface of the detection disk 32. The abutting block 323 can prevent the detection needle 322 from directly sliding out of the needle hole 321 as much as possible, and the setting of the abutting block 323 can ensure that the initial heights of the two detection needles 322 are the same. A detection column 34 is fixedly arranged on the upper end surface of the detection disk 32. A detection block 341 is slidably arranged on the detection column 34. A balance rod 342 is rotatably arranged on the detection block 341. The moving direction of the detection block 341 is perpendicular to the rotation axis of the balance rod 342. In this embodiment, the center point of the balance rod 342 is rotatably connected to the detection block 341. The tops of the two detection needles 322 are both in sliding contact with the bottom of the balance rod 342, and the distances from the two detection needles 322 to the center point of the balance rod 342 are the same. Two groups of laser sensors 35 are arranged on the detection disk 32. The two groups of sensors are arranged along the length direction of the balance rod 342, and the distances from the two laser sensors 35 to the center of the balance rod 342 are the same. When the balance rod 342 is in a horizontal state, the laser emitted by the laser sensor 35 passes close to the uppermost end of the balance rod 342. Two light receivers 36 corresponding to the laser sensors 35 one by one are arranged on the detection disk 32 (combined with Figure 5 ).

[0023] When it is necessary to detect whether the cap 5 on the bottle body 4 is tightened, the nut-screw rod assembly is started. The nut in the nut-screw rod assembly moves downward, driving the detection disc 32 to move downward, thereby driving the detection needle 322 on the detection disc 32 to move downward. The downward stroke of the detection disc 32 can be set as a fixed stroke, and the distance between the detection needle 322 on the detection disc 32 and the bottle body 4 with the tightened cap is relatively fixed. During the downward movement of the detection disc 32, the downward stroke of the detection needle 322 is the distance between the detection needle 322 and the bottle body 4 with the tightened cap. Therefore, if the cap on the bottle body 4 to be detected is in a normally tightened state, the height of the entire bottle body 4 is determined, that is, the distance between the bottle body 4 and the detection is preset. Therefore, when the detection disc 32 and the detection needle 322 move downward to a specific distance, the bottom of the detection needle 322 on the detection disc 32 just touches the upper end of the cap on the bottle body 4, and at this time, the detection needle 322 will not displace.

[0024] If the cap is not tightened, the height of the cap will be higher than the height of the normally tightened cap. Therefore, the actual distance between the bottle body 4 with the untightened cap and the detection needle 322 on the detection disc 32 will be less than the downward stroke of the detection disc 32 and the detection needle 322. Therefore, when the detection disc 32 and the detection needle 322 move downward a specific stroke, the detection needle 322 will touch the cap on the bottle body 4, and the cap on the bottle body 4 will exert an upward thrust on the detection needle 322, causing the detection needle 322 to move upward along the axis direction of the needle hole 321. The upward movement of the detection needle 322 will exert an upward thrust on the balance rod 342. Therefore, the balance rod 342 and the detection block 341 will move upward along the axis direction of the detection column 34. The upward movement of the balance rod 342 will block the laser emitted by the laser sensor 35. Therefore, the laser emitted by the laser sensor 35 cannot be transmitted to the corresponding light receiver 36. The light receiver 36 cannot receive light, and the light receiver 36 will transmit this signal to the control center. After receiving this signal, the control center can determine that the cap on the bottle body 4 is in an untightened state, and then the control center will sort the bottle body 4 with the untightened cap to a specific position through the subsequent sorting equipment.

[0025] If one of the two light receivers 36 can receive the laser emitted by the laser sensor 35 and the other light receiver 36 cannot receive the laser emitted by the laser sensor 35, it means that the two ends of the balance rod 342 are not at the same height at this time, that is, the balance rod 342 is in a tilted state. Therefore, it can be explained that after the two detection needles 322 are pushed by the cap, the upward strokes of the two detection needles 322 are inconsistent when moving upward. Therefore, it can be determined that the cap is also in a tilted state at this time. When the cap is screwed on the bottle body 4 in a tilted state, the connection tightness between the cap and the bottle body 4 is still low, and the liquid in the bottle body 4 still leaks, or air enters the bottle.

[0026] Generally speaking, the detection mechanism 3 in this embodiment can not only detect the tightened state of the bottle cap and the normal untightened state of the bottle cap, but also detect that the bottle cap is tightened on the bottle body 4 in an inclined state. When the bottle cap is tightened on the bottle body 4 in an inclined state, the connection sealing performance between the bottle cap and the bottle body 4 still cannot meet the requirements. Therefore, compared with the traditional method of judging whether the bottle cap is tightened by detecting the torque of the bottle cap, it has higher accuracy; in addition, compared with another traditional detection method based on image recognition, image recognition can have relatively high detection efficiency, and image recognition and a high-definition camera can also determine whether the bottle cap is in an inclined state. However, the equipment for detecting by image recognition generally has a relatively high price, and the reason for accurate image recognition lies in the use of a high-definition camera, and the use environment of the high-definition camera is relatively harsh. Dust and light in the air can have a great impact on its imaging result. Therefore, for the equipment for detecting by image recognition, its detection result has great instability. Therefore, through comprehensive comparison, the setting of the detection needle 322 and the balance rod 342 in this embodiment can not only detect the inclined state of the bottle cap, but also the influence of external factors on its detection result is relatively small. Therefore, it has higher accuracy for the result of whether the bottle cap is tightened.

[0027] Among them, referring to Figure 1 、 Figure 2 and Figure 3 , in this embodiment, a rotating member 37 for driving the detection disk 32 to rotate around its own axis is further provided. The rotating member 37 in this embodiment is set as a rotating motor 371 and a connecting frame 372. There are two connecting frames 372 in this embodiment. The rotating motor 371 is fixedly connected to the nut in the nut-screw assembly through the connecting frame 372. The rotating motor 371 is located directly above the detection disk 32, and the output shaft of the rotating motor 371 is coaxially arranged with the detection disk 32. A connecting rod is arranged between the output shaft of the rotating motor 371 and the detection disk 32. Similarly, there are two connecting rods in this embodiment. The two connecting rods are oppositely arranged on both sides of the detection disk 32. One end of the connecting rod is fixedly connected to the side wall of the detection disk 32, and the other end of the connecting rod is fixedly connected to the side wall of the output shaft of the rotating motor 371.

[0028] When the nut-screw rod assembly drives the detection disk 32 and the detection needle 322 to move downward to a specific stroke, the lower end of the detection needle 322 abuts against the upper end surface of the bottle cap on the bottle body 4. Then, the rotation motor 371 is started, and the rotation motor 371 drives the detection disk 32 to rotate around its own axis. Therefore, the two detection needles 322 will rotate around the axis of the bottle cap. The moving path of the bottoms of the two detection needles 322 on the upper end of the bottle cap is circular. Since the round cap itself is annular, when it is screwed onto the bottle body 4, it can be tilted in all directions, that is, it can be tilted in the 360-degree direction. When the detection needle 322 rotates on the bottle cap, the detection needle 322 can perform an all-round detection of the bottle cap to avoid the situation where when the bottle cap is in an inclined state, the contact point between the detection needle 322 and the bottle cap happens to be at the same height as the contact point between the detection needle 322 and a normal bottle cap. Therefore, the setting of the rotating member 37 further improves the accuracy of the detection mechanism 3 in this application.

[0029] Secondly, continue to refer to Figure 1 and Figure 2 In this embodiment, a reset member for restoring the balance rod 342 to the same height is further provided on the bracket 31. The reset member in this embodiment is set as a reset block 38. The reset block 38 is arranged in the horizontal direction. An electric telescopic rod 381 is provided on the bracket 31. One end of the reset block 38 is fixedly installed on the output shaft of the electric telescopic rod 381. When the driving member 33 and the rotating member 37 drive the detection disk 32 and the detection needle 322 to move up and down and rotate, the electric telescopic rod 381 is in a contracted state, and the reset block 38 is not in the moving path of the detection disk 32 and the detection needle 322. Therefore, the reset block 38 will not affect the normal operation of the detection mechanism 3. When the detection mechanism 3 finishes detecting the bottle cap on a detected bottle body 4 and needs to restore both sides of the balance rod 342 to the same height, the output shaft of the electric telescopic rod 381 will extend, thereby driving the reset block 38 to move in a direction away from the bracket 31 until the reset block 38 is directly above the balance rod 342. Then, when the detection disk 32 and the detection column 34 are driven by the nut-screw rod assembly to move upward, the upper end of the balance rod 342 on the detection column 34 will abut against the lower end of the reset block 38. Then, since the balance rod 342 is in an inclined state, the balance rod 342 will rotate until the upper end surface of the balance rod 342 is completely attached to the lower end of the reset block 38, thereby realizing the state of restoring the balance rod 342 to the same height on both sides. Since the upper ends of the two detection needles 322 are in contact with the lower end of the balance rod 342, when the heights on both sides of the balance rod 342 are the same, the detection needles 322 can also be restored to the same height state under the action of the balance rod 342, so that the detection mechanism 3 can continue to detect the next bottle body 4.

[0030] At the same time, in the present embodiment, a reset groove 382 is further provided on the lower end surface of the reset block 38, and the shape of the reset groove 382 is adapted to the shape of the upper end portion of the balance bar 342, so that the upper end portion of the balance bar 342 can be relatively perfectly embedded in the reset groove 382. The setting of the reset groove 382 can not only restore the heights of both sides of the balance bar 342 to an equal state, but the reset groove 382 can also provide certain guidance and limiting effects on the balance bar 342, thereby minimizing the possibility of lateral deviation of the balance bar 342, resulting in the two detection needles 322 not being restored to an equal height state, and further resulting in a decrease in the detection accuracy of the detection mechanism 3.

[0031] Finally, refer to Figure 3 and Figure 4 In this embodiment, light-transmitting blocks 343 are respectively arranged on both sides of the balance bar 342. The two light-transmitting blocks 343 correspond to the two laser sensors 35 one by one. The light-transmitting blocks 343 are provided with multiple light-transmitting layers 3431 along the vertical direction, and the transmittance of each light-transmitting layer 3431 gradually decreases from top to bottom. The laser emitted by the laser sensor 35 passes through the uppermost end of the light-transmitting block 343.

[0032] When the bottle cap is not tightened, the two detection needles 322 will move upward due to the thrust of the bottle cap, and the upward movement of the detection needles 322 will drive the detection block 341 and the balance bar 342 to move upward, so that the light-transmitting block 343 on the detection block 341 will move upward, so that the laser sensor 35 will pass through the light-transmitting block 343. Since the light-transmitting block 343 is composed of multiple light-transmitting layers 3431, and the light transmittance of each light-transmitting layer 3431 gradually decreases from top to bottom, the degree to which the bottle cap is not tightened, that is, the degree of sealing between the bottle cap and the bottle body 4, can be judged according to the strength of the light signal received by the light receiver 36. The weaker the received light signal is, the higher the balance bar 342 and the light-transmitting block 343 are moved up, that is, the higher the detection needle 322 is moved up, which means that the actual distance between the bottle cap and the detection needle 322 is shorter, and further means that the connection sealing between the bottle cap and the bottle body 4 is less tight; on the contrary, the stronger the light signal received by the light receiver 36 is, the higher the connection sealing between the bottle cap and the bottle body 4 is, and then the staff can judge whether there is a serious problem with the screw cap device 12 on the filling machine 1 according to the signal strength data of the light receiver 36 each time, so as to facilitate the staff to repair it in time.
