[0023] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The present embodiment provides a detection mechanism for the presence or absence of a filter assembly in a suction tubular container, comprising a movable detection member 1, the detection member 1 being arranged corresponding to the tubular container 14, the detection member 1 being connected to a reset member 2, the detection member 1 being provided with a blocking portion 3 in contact with the filter assembly 15, the blocking portion 3 being provided with an avoidance groove 100 adapted to the tubular container 14 on the filter assembly 15, a detection sheet 4 being fixed to the detection member 1, a proximity switch 5 cooperating with the detection sheet 4 being provided in the sliding direction of the detection member 1, the detection sheet 4 being located between the proximity switch 5 and the tubular container 14, the detection member 1 being connected to a driving assembly, the driving assembly being used to adjust the distance between the detection member 1 and the tubular container 14. Figure 1 and attached Figure 5 , the driving component drives the detection member 1 to move toward the tubular container 14, and the proximity switch 5 moves with the detection member 1 toward the tubular container 14. The blocking portion 3 on the detection member 1 is blocked by the filter assembly 15 on the tubular container 14, and the detection member 1 drives the detection sheet 4 to slide toward the proximity switch 5. The proximity switch 5 detects the detection sheet 4 and sends a signal. At this time, the reset member 2 is deformed. If there is no filter assembly 15 on the tubular container 14, the tubular container 14 will enter along the avoidance groove 100, and the detection member 1 will not be blocked, and will not drive the detection sheet 4 to slide toward the proximity switch 5, and the proximity switch 5 will not detect the detection sheet 4. In the above manner, it is easy to determine whether there is a filter assembly 15 on the tubular container 14. After the detection is completed, the driving component drives the detection member 1 away from the tubular container 14, and the blocked detection member 1 will slide forward under the action of the reset member 2, thereby driving the detection sheet 4 away from the proximity switch 5.

[0025] As another embodiment of the utility model: the driving assembly includes a lifting cylinder 6 and a support plate 7, the reset member 2 is arranged between the support plate 7 and the detection member 1, the reset member 2 is sleeved on the detection member 1 and connected to the support plate 7, the detection member 1 is slidably connected to the support plate 7, the lifting cylinder 6 drives the support plate 7 to move, and the support plate 7 drives the detection member 1 to move. If the detection member 1 is blocked, the detection member 1 slides in the support plate 7, and the reset member 2 is deformed. After the detection member 1 is released from the blocked state, the reset member 2 drives the detection member 1 to reset. The proximity switch 5 is fixed to the support plate 7 by a connecting member. When the lifting cylinder 6 drives the support plate 7 to move, it will also drive the proximity switch 5 to move.

[0026] As another embodiment of the present invention, the blocking portion 3 is trumpet-shaped, and the filter assembly 15 will be blocked by the inner wall of the blocking portion 3 after entering the blocking portion 3, while the tubular container 14 can directly pass through the avoidance groove 100 on the blocking portion 3 to enter the detection element 1.

[0027] Specifically, the reset member 2 is a reset spring sleeved on the detection member 1, one end of the reset spring is connected to the detection member 1, and the other end is connected to the support plate 7. When the detection member 1 is blocked, the detection member 1 compresses the reset spring when driving the detection sheet 4 to slide toward the proximity switch 5. When the detection member 1 is no longer blocked, the reset spring forces the detection member 1 to return to its initial position, thereby restoring the detection function of the detection member 1.

[0028] Specifically, a linear bearing 8 is provided between the support plate 7 and the detection member 1 , and this arrangement can further reduce the friction between the support plate 7 and the detection member 1 , so that the detection member 1 can slide more smoothly.

[0029] As another implementation of the utility model: a spring cavity 10 is provided in the support plate 7 , and there are two linear bearings 8 , with the upper linear bearing 8 being provided in the spring cavity 10 .

[0030] Refer to the attached Figure 3 There are multiple detection pieces 1, and the multiple detection pieces 1 are divided into two groups. The two groups of detection pieces 1 are staggered. This setting is because the tubular container 14 is also divided into two groups with staggered distribution, and one detection piece 1 corresponds to one tubular container 14.

[0031] As another implementation mode of the present utility model: the detection sheet 4 is sleeved on the lower end of the detection member 1 , and the detection sheet 4 is arranged below the support plate 7 .

[0032] Another implementation manner of the proximity switch 5 sensing the detection sheet 4: when the detection sheet 4 is fixed to the outer wall of the blocking portion 3, the proximity switch 5 is fixed to the top of the support plate 7, and when the detection member 1 is blocked by the filter assembly 15, it drives the detection sheet 4 to move toward the proximity switch 5, so that the proximity switch 5 can sense the detection sheet 4.

[0033] As another embodiment of the present invention: Figure 4 The tubular container 14 is clamped in the fixture 9, and a baffle 11 that can move up and down is provided above the tubular container 14. Before the detection of the detection member 1, the baffle 11 is moved down to make all the tubular containers 14 at the same horizontal position, so that the detection effect of the filter assembly 15 can be effectively guaranteed.

[0034] As another embodiment of the present invention: Figure 2 The present embodiment further includes a horizontal plate 12 and two lifting rods 13. The horizontal plate 12 and the support plate 7 are respectively fixed at both ends of the lifting rod 13. The lifting cylinder 6 is arranged between the two lifting rods 13. The lifting cylinder 6 is arranged between the support plate 7 and the horizontal plate 12. Specifically, the lifting cylinder 6 is arranged above the horizontal plate 12. This structural design makes the detection mechanism more compact and can effectively reduce the height of the detection mechanism.

[0035] In the utility model, the baffle 11 rises to the highest position under the action of the cylinder. After the conveying mechanism brings the tubular container 14 to the designated position, the baffle 11 descends a certain distance to make the top of the tubular container 14 flush. The detection member 1 rises under the action of the lifting cylinder 6. After rising to a certain distance, the tubular container 14 with the filter assembly 15 will be blocked by the blocking portion 3. When the detection member 1 continues to rise, the detection member 1 slides toward the proximity switch 5 to drive the detection sheet 4 to move downward. The proximity switch 5 detects the detection sheet 4, and the reset spring is compressed at this time; for the tubular container 14 without the filter assembly 15, when the detection member 1 rises, the tubular container 14 will enter along the avoidance groove 100 and avoid the blocking portion 3. The detection member 1 will not slide downward, and the proximity switch 5 will not detect the detection sheet 4. In the above manner, it is possible to quickly determine whether the tubular container 14 has a filter assembly 15, and transmit the signal to the back station. After the detection is completed, the lifting cylinder 6 drives the detection member 1 to descend, and the detection member 1 is reset under the action of the reset spring. The utility model sets a blocking portion 3 according to the characteristic that the diameter of the filter assembly 15 is larger than the diameter of the tubular container 14, so that the tubular container 14 can pass through the blocking portion 3, while the filter assembly 15 is blocked by the blocking portion 3, and then cooperates with the detection member 1, the detection sheet 4, the proximity switch 5, the reset member 2 and the driving assembly to quickly detect whether the non-metallic filter assembly 15 exists on the tubular container 14.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
