Description

Technical Field

[0001] This invention relates to the field of down loft testing technology, specifically a functional down home textile semi-finished product inspection device. Background Technology

[0002] The performance testing of down home textiles mainly involves testing the performance of down. The testing items for down performance include down content, loft, oxygen consumption, etc. In this invention, it mainly refers to testing the loft of down. In the process of testing the loft of down, the down needs to be pre-treated first. The pre-treated down is poured into a regular cylinder, and then a blower is pressed onto the top of the cylinder to blow it. This is to prevent uneven stress on the down during the pouring process, which could affect the final test results. After blowing and natural settling, the loft is tested. A regular pressure plate is gently placed on the surface of the down, and the value of the pressure plate on the cylinder is read after a specified time. If necessary, the test can be repeated.

[0003] In the aforementioned blown-down process: To ensure the accuracy of the test results to the greatest extent, the cylinder is regular in shape, meaning that functional structures such as rounded corners or guide plates cannot be set at the bottom of the cylinder. This results in a weak disturbance zone near the side wall or corner area during the blowing process. Although mechanical disturbances (such as stirring, vibration, beating, and other physical contact methods) can improve the uniformity of down distribution, mechanical disturbances are usually avoided during down loft testing to prevent damage to the natural loft structure of down.

[0004] In view of the above-mentioned technical problems, we propose a functional down home textile semi-finished product inspection device. Summary of the Invention

[0005] [Technical problems solved] To address the shortcomings of existing technologies, this invention provides a functional down home textile semi-finished product inspection device, which has advantages such as multi-dimensional down blowing and no mechanical disturbance, and can effectively solve the problems in the background technology.

[0006] [Technical Solution] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a functional down home textile semi-finished product inspection device, comprising a detection container and a down blowing disc that can be covered on the top of the detection container. The down blowing disc is used to blow down during the down blowing process. A fluid blowing mechanism is provided at the bottom of the detection container. The fluid blowing mechanism is configured to blow at least vertically upward, and is used to synchronously blow down in conjunction with the down blowing disc during the down blowing process.

[0007] Preferably, the inspection device further includes a pressure plate, and air holes are provided on the blowing plate. The pressure plate and the blowing plate are optional installations made by those skilled in the art based on the actual implementation situation and with reference to the prior art, and are not intended to further limit the technical features of the present invention.

[0008] Preferably, the fluid jetting mechanism includes at least one nozzle capable of vertically upward jetting, the nozzle being connected to an external air supply device, and the fluid jetting mechanism further includes a rotating component disposed at the bottom of the detection container, the rotating component being rotatable based on the detection container, used to drive the nozzle to move circumferentially based on the axis of the detection container during the jetting process.

[0009] Preferably, the air supply device can be an air pump, which is an optional installation made by those skilled in the art based on the actual implementation situation and with reference to the prior art, and is not intended to further limit the technical features of the present invention.

[0010] Preferably, any rotary drive component known and understood by those skilled in the art can be used to drive the rotating component to rotate, such as a motor or a motor + reducer.

[0011] Preferably, the rotating component is connected to the testing container via a rotating dynamic seal, or a regular rotating connection, so that down from inside the testing container is not allowed to pass through at the connection between the rotating component and the testing container.

[0012] Preferably, the nozzle is provided with a swing drive, which is configured to drive the nozzle to swing during the spraying process, so as to change the spraying direction of the nozzle.

[0013] Preferably, this can be achieved by adding a separate swing mechanism to the nozzle.

[0014] Preferably, the oscillating drive includes an inclined plate, which is fixedly connected to the nozzle. A limiting member is movably connected to the nozzle, which is used to limit and guide the movement of the nozzle in a spherical fan-shaped oscillation during the rotation of the nozzle driven by the inclined plate.

[0015] Preferably, the nozzle can be fixedly connected to the axis of the tilting disk. To reduce the oscillation amplitude of the nozzle, the nozzle can be eccentrically connected to the tilting disk based on the axis of the tilting disk, such as... Figure 6 The structure shown is in a certain state.

[0016] Preferably, a force-bearing component is provided on the tilting disk, which is used to drive the tilting disk to rotate synchronously during the rotation under force. A force-applying part is provided on the detection container at a position corresponding to the force-bearing component, which is configured to drive the force-bearing component to rotate when the force-bearing component moves on the force-applying part.

[0017] Preferably, the force-bearing component is a gear, and the force-applying part on the detection container is a gear ring that meshes with the gear. When the gear, as the force-bearing component, moves circumferentially around the force-applying part while meshing with the gear ring, the force-bearing component will rotate on its own, thereby driving the tilting disk to rotate synchronously.

[0018] Preferably, an axially movable force-applying component is provided between the tilting disk and the force-receiving component, which is used to change the tilt angle of the tilting disk when moving axially. The force-applying component is movably connected to the tilting disk but cannot rotate relative to it based on the axis of the force-applying component, and is configured such that the force-receiving component rotates synchronously with the tilting disk through the force-applying component during the rotation under force.

[0019] As a preferred option, the force-applying component is as follows: Figure 6 The shaft shown has a linear groove on the tilting plate, and the force-applying component is movably connected to the tilting plate based on the linear groove. The movable connection but not relative rotation based on the axial direction of the force-applying component means that the force-applying component can only rotate based on a single radial direction of the tilting plate or slide inside the linear groove, but cannot rotate relative to the tilting plate based on its axial direction. This allows the tilting plate to rotate synchronously during the rotation of the force-applying component.

[0020] Preferably, the synchronous rotation of the inclined plate by the force-applying component during the rotation of the force-bearing component means that the inclined plate is rotated synchronously by rotating the force-applying component or the support plate. Since the force-applying component is connected to the inclined plate, considering the need for axial movement of the force-applying component, the force-applying component is preferably a spline shaft. When a support plate is provided, for example, the inclined plate is indirectly driven to rotate by being fixedly connected to the force-bearing component through the support plate. The force-applying component can be connected to the force-bearing component and / or the support plate by a spline. In the absence of a support plate, the force-applying component can be directly connected to the force-bearing component by a spline.

[0021] Preferably, since there is an operational requirement to rotate / move axially of the force-applying component, as shown in the figure, the circumferential movement of the force-receiving component and the axial movement of the force-applying component can be driven by a moving drive component.

[0022] Preferably, in the moving drive component, a rotary drive component such as a motor or a motor + reducer drives the force-bearing component to move circumferentially. A sliding frame is provided between the force-bearing component and the moving drive component, and a reversing gear set is provided between the sliding frame and the rotary drive component, so that the rotation axis of the sliding frame is not on the same axis as the output axis of the rotary drive component. Simultaneously, the sliding frame is rotatably connected to the force-bearing component, which can be connected via bearings. To enable axial movement of the sliding frame, a linear movement drive component is provided on one of the gears connected to the sliding frame in the reversing gear set. The linear movement drive component can only slide circumferentially relative to this gear via a connecting member, and cannot move axially relative to it. This ensures that the axial movement of the connected gear is achieved without interfering with the rotation of the gear, and that the sliding frame can be driven to move axially while rotating.

[0023] Preferably, the force-bearing component is embedded in the detection container and can only move circumferentially, but not axially.

[0024] Preferably, the linear motion drive is any linear motion drive that is well known and understood by those skilled in the art, such as an electric actuator, hydraulic cylinder, or pneumatic cylinder, capable of driving the connected gear to move linearly in its axial direction.

[0025] Preferably, the limiting member includes a movable member that rotates with the nozzle in a single radial direction, and a limiting block is movably connected to the movable member. A sliding portion is provided at one end of the limiting block away from the nozzle. A limiting portion is provided on the detection container at a position corresponding to the sliding portion, and the sliding portion is slidably connected to the limiting portion.

[0026] Preferably, the limiting member includes a movable member that rotates with the nozzle in a single radial direction, meaning that one end of the movable member is rotatably connected to the nozzle and the other end is movably connected to the limiting block.

[0027] Preferably, an arc-shaped groove is provided on the limiting block, and a ball head that fits the structure of the arc-shaped groove is provided on one end of the movable part connected to the arc-shaped groove.

[0028] Preferably, the rotating member has a chamber that allows the nozzle to swing. One end of the chamber, which is connected to the detection container, is a through hole. A sealing member is provided between the rotating member and the nozzle. The sealing member is used to seal the end of the chamber away from the through hole, so that the fluid in the chamber can only flow out to the detection container through the through hole.

[0029] Preferably, the seal is a sealing cup-shaped rubber, such as Figure 3The structure shown has one end fixedly connected to the nozzle and the other end fixedly connected to the rotating part.

[0030] Preferably, a universal joint is provided on the nozzle, and the nozzle is connected to an external air supply device through the universal joint.

[0031] Preferably, to ensure proper fluid flow during the circumferential movement of the nozzle, a connecting component, which is a pipe, is provided at the universal joint of the nozzle. Figure 8 The structure shown is umbrella-shaped and has a main pipe that passes through the external air supply device of the reversing gear set in the moving drive component. In order to ensure that the nozzle can communicate with the fluid normally during the swinging process, a hose is provided between the connecting component and the universal joint on the nozzle to compensate for the ball-fan swinging operation of the nozzle.

[0032] [Beneficial Effects] Compared with the prior art, the present invention provides a functional down home textile semi-finished product inspection device, which has the following beneficial effects: This functional down home textile semi-finished product inspection device has a fluid blowing mechanism at the bottom of the inspection container that can spray fluid vertically upwards. In the down blowing process, the down inside the inspection container is blown vertically upwards in conjunction with the down blowing disc. This can eliminate dead corner areas in the down blowing process and make the down as loose and uniform as possible without damaging the down's fluffy structure. Attached Figure Description

[0044] To make the technical means, creative features, achieved objectives, and functional effects of this invention readily understandable, the invention will be further described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0045] Example 1 To address the shortcomings of existing technologies, such as Figure 1 As shown, the present invention provides a functional down home textile semi-finished product inspection device, including a detection container 1 and a down blowing disc that can be covered on the top of the detection container 1. The down blowing disc is used to blow down during the down blowing process. The device is characterized in that a fluid blowing mechanism 3 is provided at the bottom of the detection container 1. The fluid blowing mechanism 3 is configured to blow at least vertically upward, and is used to synchronously blow down in conjunction with the down blowing disc during the down blowing process.

[0046] The inspection device also includes a pressure plate 2, which has air holes on the blowing plate. The pressure plate 2 and the blowing plate are optional installations made by those skilled in the art based on existing technology for actual implementation. In this embodiment, they are not intended to further limit the technical features of the present invention.

[0047] It should be noted that during the down loft test, the pre-treated down is placed inside the test container 1. In order to ensure that the down is evenly dispersed and does not form clumps or uneven accumulation that would interfere with the test results, a down blowing process is required. At this time, a down blowing plate needs to be installed on the upper end of the test container 1. The down blowing plate is connected to an external air supply device. The down blowing plate is used to prevent the down from flying out of the test container 1 during the down blowing process. During the blowing process, the airflow from the blowing disc blows the down vertically downwards into the test container 1. At the same time, the fluid blowing mechanism 3 located at the bottom of the test container 1 is connected to the external air supply to blow the down inside the test container 1 simultaneously from top to bottom, so as to ensure the uniform mixing of the down before the loft test. Then, the pressure plate 2 is placed on the down without any external force applied, so that the weight of the pressure plate 2 presses down on the down inside the testing container 1. The distance the pressure plate 2 moves down is calculated within a certain period of time to determine the qualification of the down's loft.

[0048] It is worth mentioning that by setting a fluid spraying mechanism 3 at the bottom of the testing container 1 for spraying fluid vertically upwards, the down inside the testing container 1 is sprayed vertically upwards in conjunction with the down blowing disc during the down blowing process. This can eliminate dead zones in the down blowing process and maximize the uniformity of the down's looseness without damaging the down's tuft structure.

[0049]

Example 2

[0050] The air supply device can be an air pump, which is an optional installation made by those skilled in the art based on the actual implementation situation and with reference to the prior art. In this embodiment, it is not intended to further limit the technical features of the present invention. In this embodiment, any rotation drive component known and understood by those skilled in the art can be used to drive the rotating component 31 to rotate. For example, it can be a motor, a motor + reducer, or similar rotation drive components. The rotating component 31 is preferably connected to the detection container 1 by a rotating dynamic seal, or by a normal rotating connection, so that down inside the detection container 1 is not allowed to pass through at least at the connection between the rotating component 31 and the detection container 1.

[0051] It should be noted that the present invention is a functional down home textile semi-finished product inspection device. In this embodiment, the fluid blowing mechanism 3 is set up to blow the inside of the test container 1 through the nozzle 32 connected to the air supply device. By blowing down feathers, the rotating component 31 is driven to rotate. During the rotation of the rotating component 31, the nozzle 32 located on it is driven to move in a circle, thereby changing the blowing position of the nozzle 32 on the detection container 1. In this embodiment, there are at least two blowing directions, namely the straight blowing direction of the nozzle 32 and the blowing direction after the rotating component 31 drives the nozzle 32 to move in a circle.

[0052] It is worth mentioning that, compared with the fixed-point blowing in the first embodiment above, in this embodiment, the nozzle 32 can be driven to move circumferentially at least to achieve a rotating sweeping airflow field, ensuring that the down at any position in the container can be periodically impacted and disturbed, completely eliminating dead corners in the horizontal direction, and achieving true full-volume uniform loosening.

[0053] Furthermore, to increase the dimension of the spray direction of nozzle 32, and as... Figure 2 , 3 As shown, a fluid jetting mechanism 3 for a functional down home textile semi-finished product inspection device has a swing drive 331 on the nozzle 32, which is configured to drive the nozzle 32 to swing during the jetting process, so as to change the jetting direction of the nozzle 32. In this embodiment, it can be achieved by adding a separate swing mechanism to the nozzle 32.

[0054] It should be noted that the present invention is a functional down home textile semi-finished product inspection device. Through the fluid spraying mechanism 3, in this embodiment, during the spraying process of the nozzle 32, not only can the rotation of the rotating member 31 drive the nozzle 32 to move in a circular motion, but the swinging drive member 331 can also make the nozzle 32 swing in a spherical fan shape. Thus, during the spherical fan-shaped swinging operation of the nozzle 32, the nozzle 32 is not limited to straight spraying on the circumferential path of the rotating member 31, but can also perform swinging spraying. For example, it can swing from the orientation towards the wall of the detection container 1 to the orientation towards the center of the detection container 1, adding another dimension on the basis of having two dimensions of spraying direction.

[0055] It is worth mentioning that, compared with the blowing method in the above embodiment which can at least drive the nozzle 32 to move circumferentially, in this embodiment, at least during the circumferential movement of the nozzle 32, it can make a spherical fan-shaped swing, thereby forming at least a spiral and umbrella-shaped composite airflow field, which can achieve multi-angle impact on the interior of the detection container 1 and eliminate any dead corners in three-dimensional space to the greatest extent.

[0056] As a preferred embodiment, such as Figure 3 As shown, a chamber 311 is provided on the rotating member 31 to allow the nozzle 32 to swing. One end of the chamber 311 connected to the detection container 1 is a through hole, and a sealing member 312 is provided between the rotating member 31 and the nozzle 32. The sealing member 312 is used to seal the end of the chamber 311 away from the through hole, so that the fluid in the chamber 311 can only flow out to the detection container 1 through the through hole.

[0057] Among them, the seal 312 is a sealing cup-shaped rubber, such as Figure 3The structure shown has one end fixedly connected to the nozzle 32 and the other end fixedly connected to the rotating part 31.

[0058] Furthermore, such as Figure 4 As shown, a swing drive 331 is used in the fluid blowing mechanism 3 of a functional down home textile semi-finished product inspection device. The swing drive 331 includes an inclined plate 3312, which is fixedly connected to the nozzle 32. A limiting member 3311 is movably connected to the nozzle 32. The limiting member 3311 is used to limit and guide the movement of the nozzle 32 in a spherical fan-shaped swing during the rotation of the nozzle 32 driven by the inclined plate 3312.

[0059] In a preferred embodiment, the nozzle 32 may be fixedly connected to the axis of the tilting disk 3312. To reduce the oscillation amplitude of the nozzle 32, the nozzle 32 may be eccentrically connected to the tilting disk 3312 based on the axis of the tilting disk 3312, such as... Figure 6 The structure shown is in a certain state.

[0060] It should be noted that the present invention is a functional down home textile semi-finished product inspection device. In this embodiment, the nozzle 32 is set on the inclined plate 3312 through the swing drive component 331. If the nozzle 32 needs to be oscillating, the tilting disk 3312 is rotated. Since the tilting disk 3312 has a certain tilt angle, the nozzle 32 is deviated from the rotation axis of the tilting disk 3312. During the rotation, the nozzle 32 located on it is driven to move synchronously in a tilted circumferential direction, thereby forming a spherical fan-shaped oscillation operation. As the tilting disk 3312 rotates, it drives the nozzle 32 to move in an inclined circumferential direction. The limiting member 3311 is used to limit and guide the movement of the nozzle 32. During this process, the nozzle 32 and the limiting member 3311 are relatively movable.

[0061] As a preferred embodiment, such as Figure 5 As shown, the limiting member 3311 includes a movable member 33112 that rotates with the nozzle 32 in a single radial direction, and a limiting block is movably connected to the movable member 33112. A sliding part 33111 is provided on the limiting block at one end away from the nozzle 32. A limiting part 12 is provided on the detection container 1 at a position corresponding to the sliding part 33111, and the sliding part 33111 is slidably connected to the limiting part 12.

[0062] The limiting member 3311 includes a movable member 33112 that rotates with the nozzle 32 in a single radial direction, meaning that one end of the movable member 33112 is rotatably connected to the nozzle 32, and the other end is movably connected to the limiting block.

[0063] As a preferred embodiment, such as Figure 4 As shown, a universal joint 321 is provided on the nozzle 32, and the nozzle 32 is connected to an external air supply device through the universal joint 321.

[0064] To ensure proper fluid flow during the circumferential movement of the nozzle 32, a connecting component 322 is provided at the universal joint 321 on the nozzle 32. The connecting component 322 is a pipe, such as... Figure 8 The structure shown is umbrella-shaped and has a main pipe that passes through the reversing gear set in the moving drive unit 332 and connects to the external air supply device. In order to ensure that the nozzle 32 can communicate with the fluid normally during the swinging process, a hose is provided between the connecting member 322 and the universal joint 321 on the nozzle 32 to compensate for the spherical swinging operation of the nozzle 32.

[0065]

Example 3

[0066] Specifically, such as Figure 7 As shown, a testing container 1 for a functional down home textile semi-finished product inspection device has a force-applying part 11 provided on the testing container 1 at a position corresponding to the force-receiving member 3321. It is configured to drive the force-receiving member 3321 to rotate when the force-receiving member 3321 moves on the force-applying part 11.

[0067] In a preferred embodiment, the force-receiving component 3321 is a gear, and the force-applying part 11 on the detection container 1 is a gear ring that meshes with the gear. When the gear, which is the force-receiving component 3321, moves circumferentially around the force-applying part 11 while meshing with the gear ring, which is the force-applying part 11, the force-receiving component 3321 will rotate on its own, thereby driving the tilting disk 3312 to rotate synchronously.

[0068] It should be noted that the present invention is a functional down home textile semi-finished product inspection device. In this embodiment, the force-receiving component 3321 is a gear, and the force-applying part 11 is a gear ring that meshes with the force-receiving component 3321, which is a gear. With the nozzle 32 mounted on the tilting plate 3312, if it is necessary to make the nozzle 32 rotate while simultaneously moving it in the circumferential direction, that is, the nozzle 32 has both rotation and revolution operation processes. It is achieved by driving the nozzle 32 to move circumferentially. Since the force-receiving component 3321 connected to the nozzle 32 as a gear meshes with the force-applying part 11 as a gear ring, the force-receiving component 3321 meshes with the force-applying part 11 on the detection container 1 to form a rotation during the circumferential movement of the nozzle 32. During the rotation of the force-bearing component 3321, the tilting disk 3312 is driven to rotate synchronously. Based on the spherical fan-shaped oscillation mechanism formed by the nozzle 32 in the above embodiment 2, the nozzle 32 can be driven to perform spherical fan-shaped oscillation while moving circumferentially. Thus, when there is a blowing disk on the detection container 1, at least two blowing points can be formed inside the detection container 1, and the blowing direction formed by the nozzle 32 has at least three dimensions.

[0069]

Example 4

[0070] In this embodiment, the force-applying component 3314 is as follows: Figure 6 The shaft shown has a linear groove 33121 on the tilting disk 3312, and the force-applying member 3314 is movably connected to the tilting disk 3312 based on the linear groove 33121. The movable connection but not relative rotation based on the axial direction of the force-applying member 3314 means that the force-applying member 3314 can only rotate based on a single radial direction of the tilting disk 3312, or slide inside the linear groove 33121, and cannot be relative to the tilting disk 3312 based on its axial direction. This allows the tilting disk 3312 to rotate synchronously during the rotation of the force-applying member 3314. During the rotation of the force-bearing component 3321 under load, the tilting disk 3312 is driven to rotate synchronously by the force-applying component 3314. This means that the tilting disk 3312 is driven to rotate synchronously by rotating the force-applying component 3314 or the support disk 3313. Since the force-applying component 3314 is connected to the tilting disk 3312, and considering the need for axial movement of the force-applying component 3314, the force-applying component 3314 is preferably a spline shaft. When the support disk 3313 is provided, for example, the tilting disk 3312 is indirectly driven to rotate by the support disk 3313 being fixedly connected to the force-bearing component 3321. The force-applying component 3314 can be splined connected to the force-bearing component 3321 and / or the support disk 3313. In the absence of the support disk 3313, the force-applying component 3314 can be directly splined connected to the force-bearing component 3321. Because there is a need for rotation / axial movement of the force-applying component 3314, such as Figure 8 The structure shown can be driven by the moving drive 332 to move the force-receiving member 3321 circumferentially and the force-applying member 3314 axially. In the moving drive component 332, the force-receiving component 3321 is driven to move circumferentially by a rotating drive component 3322 such as a motor or a motor + reducer. A sliding frame is provided between the force-receiving component 3321 and the moving drive component 332, and a reversing gear set is provided between the sliding frame and the rotating drive component 3322, so that the rotation axis of the sliding frame is not on the same axis as the output axis of the rotating drive component 3322. At the same time, the sliding frame is rotatably connected to the force-applying component 3314, which can be connected by a bearing. In order to enable the sliding frame to move axially, a linear moving drive component 3323 is provided on one of the gears connected to the sliding frame in the reversing gear set. The linear moving drive component 3323 can only slide circumferentially relative to the gear through the connecting member 33231, and cannot move axially relative to it. This ensures that the rotation of the gear connected to it is not interfered with when the gear is driven to move axially. In the process of rotating the sliding frame, the sliding frame can also be driven to move axially. The force-bearing component 3321 is embedded in the detection container 1 and can only move circumferentially, but cannot move axially. The linear motion drive 3323 is any linear motion drive known and understood by those skilled in the art, such as an electric actuator, hydraulic cylinder, or pneumatic cylinder, capable of driving a gear connected thereto to move linearly in its axial direction.

[0071] It should be noted that the present invention is a functional down home textile semi-finished product inspection device. In the process of blowing down in the test container 1, if it is necessary to control the nozzle 32 to perform a ball-fan oscillation operation, the support plate 3313 or the force application member 3314 is rotated. During the rotation of the support plate 3313 or the force application member 3314, the tilting plate 3312 is driven to rotate. Under the limiting action of the limiting member 3311, the nozzle 32 is driven to perform a ball-fan oscillation operation. After blowing the down into the testing container 1, if it is necessary to make the nozzle 32 flat based on the through hole on the rotating member 31, the force-applying member 3314 is moved vertically upward without rotating the force-applying member 3314 or the support plate 3313. During the movement, the force-applying member 3314 applies force to the tilting plate 3312. Under the limiting action of the limiting member 3311, the nozzle 32 rotates at a fixed point until the nozzle 32 engages with the through hole on the rotating member 31, thus forming the desired shape. Figure 10 The joint state in the structure shown is such that the bottom of the test container 1 can be in a flat state during the subsequent process of testing the loft of the down. As described above, during the vertical movement of the force-applying component 3314, the tilting plate 3312 adapts to the relative sliding of the force-applying component 3314 based on the linear slide groove 33121 on it, in order to cope with the movement of the nozzle 32. Afterwards, if it is necessary to perform the swing spraying operation of the nozzle 32 again, the force-applying component 3314 is returned to its position height when the nozzle 32 is used for swing spraying.

[0072] Given the operating mechanism in this embodiment, those skilled in the art will understand that during the rotation of the tilting disk 3312 or the force-applying component 3314, i.e., during the oscillating spraying operation of the nozzle 32, the force-applying component 3314 should be prevented from moving in its axial direction to avoid interfering with the oscillating operation of the nozzle 32. Similarly, during the axial movement of the force-applying component 3314, i.e., during the process of engaging the nozzle 32 with the through hole on the rotating component 31, the tilting disk 3312 and the force-applying component 3314 should be prevented from rotating.

[0073] Furthermore, and such Figure 5As shown, in a functional down home textile semi-finished product inspection device, a limiting member 3311 for the swing drive 331 has an arc-shaped groove 331111 on the limiting block, and a ball head 331121 that fits the structure of the arc-shaped groove 331111 is provided at one end of the movable member 33112 connected to the arc-shaped groove 331111.

[0074] It should be noted that this invention is a functional down home textile semi-finished product inspection device. The limiting member 3311, through the cooperation of the ball head 331121 and the arc-shaped slide groove 331111, limits and guides the nozzle 32 during its spherical swing operation. As the tilting plate 3312 drives the nozzle 32 to rotate, the ball head 331121 slides and rotates within the arc-shaped slide groove 331111. Figure 10 The structure shown is in its current state. When the nozzle 32 is switched from the swinging operation state to the engaged state, the force-applying member 3314 moves axially and bears the force from the vertical direction on the tilting plate 3312. The ball head 331121 cannot move vertically under the limiting action of the arc-shaped slide groove 331111, and can only move in an arc. Thus, during the vertical movement of the force-applying member 3314, the force-applying member 3314 drives the nozzle 32 to rotate at a fixed point only based on the arc-shaped slide groove 331111 through the ball head 331121.

[0075] Example 5 Based on any one of the above embodiments one to four, in this embodiment, a liquid such as cleaning fluid can be sprayed into the inside of the detection container 1 through the nozzle 32, thereby enabling all-round spray cleaning of the inner wall of the detection container 1.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
