Description

Technical Field

[0001] The utility model relates to the technical field of soft capsules, in particular to a soft capsule depression value detection device. Background Art

[0002] Soft capsules are capsules that are sealed in spherical or elliptical soft capsule materials by directly encapsulating a certain amount of liquid medicine, or dissolving or dispersing solid components in suitable excipients to form solutions, suspensions, emulsions or semi-solids. They are commonly found in medicines or health foods. Currently, soft capsules are also used in the tobacco industry. In some cigarette products, spherical soft capsules (usually called popping beads) wrapped with flavoring liquid are placed in the filter tip. Crushing the popping beads during smoking can improve the taste of the cigarette.

[0003] The indentation value refers to the amount of deformation that occurs when a soft capsule is subjected to pressure. It is used to judge the elasticity or hardness of the soft capsule and is an indicator for judging the quality of the soft capsule. Different products have different standards for the indentation value of soft capsules. For example, in the tobacco industry, the hardness of the popping bead should be a moderate value. When the hardness of the popping bead is too low, it is easy to break during the production and cigarette packaging process. When the hardness of the popping bead is too high, it is not easy to be bitten during the smoking process, which affects the consumer's use.

[0004] The indentation value of soft capsules is usually measured by using equipment with pressure detection and displacement detection functions. For example, the patent document with publication number CN107621406A discloses a method for detecting the strength and deformation of cigarette capsule particles. The detection method is as follows: place the cigarette capsule sample on the sample platform; when the test electric platform or the sample pressure head is in the initial position and gradually approaches the cigarette capsule sample, until the sample pressure head contacts the cigarette capsule sample, the pressure sensor senses the pressure applied to the sample, and the system records the initial distance or displacement of the sample pressure head as L1. The sample pressure head continues to move downward and squeeze the capsule. At this time, the pressure sensor records the pressure value N1, and the displacement sensor records the moving distance or displacement of the sample pressure head as L2. The above method can be used to judge the deformation characteristics of the capsule under continuously increasing pressure and determine the pressure required for capsule crushing, but in the industrial production process, there is usually a fixed quality standard for soft capsules, that is, it is only necessary to judge whether the deformation of the soft capsule is qualified when a specific pressure is applied. When the above method is applied in industrial production, the detection efficiency is too low, and the parameter adjustment is relatively troublesome, which is not conducive to the rapid detection of products. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a soft capsule depression value detection device, which can quickly detect and judge whether the depression value of the soft capsule is qualified, and is suitable for industrial production.

[0006] In order to achieve the above purpose, the utility model adopts the following technical means:

[0007] A soft capsule depression value detection device comprises a loading platform, a support platform arranged above the loading platform, a detection platform arranged above the support platform, and a mounting frame fixedly connecting the loading platform, the support platform and the detection platform, a displacement transmission component and a pressure transmission component are arranged between the support platform and the mounting platform, and a displacement detector is connected to the detection platform; a vertically penetrating mounting hole is formed in the middle of the support platform, the displacement transmission component comprises a connecting block located on the upper side of the support platform and a crimping block connected to the connecting block and passing through the mounting hole; the pressure transmission component comprises a connecting rod and a counterweight block, the connecting rod passes through the connecting block horizontally, the part of the connecting rod close to the first end is hinged to the mounting frame, and the part of the connecting rod close to the second end is connected to the counterweight block.

[0008] The utility model uses a connecting rod and a counterweight block to apply pressure to the connecting block, thereby causing the crimping block to apply pressure to the capsule below, causing the capsule to deform, and then uses a displacement detector to detect the position change of the connecting block before and after the capsule is deformed, so as to measure the capsule's depression value. The utility model is used as follows: first, the soft capsule is placed on a stage without setting a counterweight block, so that the lower end of the pressure transmission component lightly touches the soft capsule, and the position L0 of the upper surface of the connecting block is detected by the displacement detector, and then the counterweight block is fixed at a predetermined position on the connecting rod, and the pressure transmission component is pressed by the counterweight block and the connecting rod, and the soft capsule is squeezed and deformed under the action of pressure, and at this time, the position L1 of the upper surface of the connecting block is detected by the displacement detector, and the difference between L1 and L0 is the depression value of the soft capsule. During the soft capsule testing process, a specific pressure is usually applied, and the depression value under the pressure is tested to see if it meets the standard. Usually, each product has a fixed test index. The utility model determines the weight of the counterweight block and the distance between the counterweight block and the connecting block under different test standards by calculation in advance. The position of the counterweight block can be adjusted based on the test index to achieve the change of pressure. In the prior art, electronic equipment is usually used to adjust the pressure. On the one hand, the equipment cost is high, and on the other hand, it needs to be connected to the current before it can be used. The utility model can adapt to different use environments, has low cost and is easy to operate. Usually for a certain type of capsule, under stable production conditions, their L0 should be a relatively constant value, so there is no need to repeatedly re-measure the L0 corresponding to each capsule, and only their corresponding L1 needs to be measured.

[0009] Furthermore, the counterweight block is slidably connected to the connecting rod, and a locking mechanism is provided on the counterweight block.

[0010] Furthermore, a socket which is slidably matched with the connecting rod is formed in the middle of the counterweight block, and a threaded hole which is connected with the socket is formed on the side of the counterweight block, and a locking piece is mounted on the threaded hole.

[0011] Furthermore, a capsule slot is provided on the loading platform.

[0012] Furthermore, a portion of the connecting rod close to the second end is provided with a scale.

[0013] Furthermore, a mating portion is provided on the connecting rod, and the mating portion includes a first mounting head facing the direction of the worktable and a second mounting head facing the direction of the detection platform, the first mounting head is installed with a first spring, and the second mounting head is installed with a second spring; a mating cavity is formed in the middle part of the connecting block, the mating portion is arranged in the mating cavity, and the first mounting head is elastically abutted against the lower cavity wall of the mating cavity through the first spring, and the second mounting head is elastically abutted against the upper cavity wall of the mating cavity through the second spring.

[0014] Furthermore, the length of the crimping block is equal to the distance between the upper surface of the stage and the upper surface of the support platform.

[0015] Furthermore, the displacement detector includes a detection head abutting against the connection block and a reading meter connected to the detection head.

[0016] Furthermore, the reading meter is a mechanical reading meter.

[0017] Furthermore, the range of the mechanical reading meter is 0~10mm.

[0018] The application of the utility model can achieve the following beneficial effects:

[0019] 1. The utility model can apply a specific pressure to the capsule through the counterweight block and the connecting rod, and use the displacement detector to detect the depression amount of the capsule, so as to judge whether the depression value of the capsule is qualified. The detection efficiency is high and it is suitable for industrial production.

[0020] 2. The utility model can change the pressure by adjusting the position of the counterweight on the connecting rod. The device can be quickly adjusted by only determining in advance the position where the counterweight should be when detecting different types of capsules. It has high flexibility and versatility.

[0021] 3. The utility model has a simple structure and reduces the use of electronic equipment compared to the prior art, which significantly reduces the cost. In some embodiments, after the reading table of the displacement monitor is set as a mechanical reading table, the device can be used without power supply. BRIEF DESCRIPTION OF THE DRAWINGS
