[0022] To make the objectives, technical solutions, and advantages of this application clearer, the application will now be described in further detail with reference to the accompanying drawings.

[0024] To facilitate understanding of the sampling device provided in this application embodiment, its application scenario is first described. The sampling device provided in this application embodiment is applied to rubber sampling. In the prior art, when sampling rubber, existing rubber sampling mechanisms can only take one sample piece per action, resulting in low sampling efficiency, inability to guarantee sample representativeness, and failure to meet the sample quantity requirements of multiple processes in actual quality inspection. Therefore, this application embodiment provides a sampling device to improve the effect and efficiency of the sampling blade during assembly. A detailed description follows with reference to specific drawings and embodiments.

[0025] refer to Figure 1 As shown, Figure 1 A reference diagram showing the usage state of the sampling device provided in this application embodiment is illustrated. The sampling device provided in this application embodiment is used to cut rubber to obtain sample pieces. Figure 1 As shown, the rubber is conveyed via a conveying device during transport, such as... Figure 1 As shown, the sampling device includes a frame 200 and a roller conveyor assembly 300, through which rubber is conveyed during transport. The sampling device is used to cut the rubber during the rubber conveying process. Figure 1 In the structure shown, the roller conveyor assembly 300 is supported by the frame 200, and the sampling device can also be supported by the frame 200. It should be understood that the frame 200 is an optional structure, and the sampling device can be supported by other support structures, not limited to the frame 200.

[0026] In a specific arrangement, the sampling device comprises at least two sampling assemblies 100, each of which can be used to cut rubber to obtain a sample. Thus, at least two samples can be obtained when cutting the sample. As shown in Figure 1 , two sampling assemblies 100 are exemplified in Figure 1 , and the two sampling assemblies 100 are arranged in a direction perpendicular to the direction of rubber transmission. During sampling, the two sampling assemblies 100 can be used to sample separately to obtain more samples.

[0027] In a specific arrangement, each sampling assembly 100 comprises a cutting assembly 110 and a pushing assembly 120; wherein the cutting assembly 110 and the pushing assembly 120 are arranged on opposite sides of the rubber. As shown in Figure 1 , each sampling device comprises a cutting assembly 110 and a pushing assembly 120, and the cutting assembly 110 and the pushing assembly 120 are arranged in the height direction of the rack 200 and are arranged on opposite sides of the rubber. Specifically, the cutting assembly 110 is located above the pushing assembly 120, and the rubber is located between the cutting assembly 110 and the pushing assembly 120.

[0028] Referring to Figure 1 and Figure 2 together, the cutting assembly 110 comprises a first follower seat 111, a cutter die 112, a pin 113, and a die plate 114. The cutter die 112 is used to cut rubber, the first follower seat 111 moves synchronously with the rubber and can be extended and retracted in the direction in which the cutting assembly 110 and the pushing assembly 120 are arranged. Specifically, the first follower seat 111 is used to support the cutter die 112, and the first follower seat 111 can move synchronously with the rubber to keep the cutter die 112 in a state of synchronization with the rubber in the direction of rubber transmission, so as to ensure that the cutter die 112 can cut the rubber. In addition, the first follower seat 111 can also be extended and retracted in the height direction of the rack 200 relative to the rubber to drive the cutter die 112 to cut the rubber. The cutter die 112 is arranged on the first follower seat 111, and the cutter die 112 has a hollow structure with a cavity for accommodating the sample. The cut sample can be accommodated in the cutter die 112.

[0029] The pin 113 is used to fix the sample to keep the cut sample in the cutter die 112. In the arrangement, the pin 113 is fixed on the first follower seat 111, and the pin 113 is located in the cutter die 112. When the cutter die 112 cuts the rubber, the pin 113 is also inserted into the sample, so that when the cutter die 112 follows the first follower seat 111 to move away from the rubber, the sample can be kept in the cutter die 112 to avoid falling. In addition, when the sample is separated from the rubber, if there is adhesion between the sample and the rubber, the pin 113 can separate the sample from the rubber by the carrying force of the pin 113, thereby improving the sampling effect.

[0030] The ejection plate 114 is used to eject the sample from the die 112. After the die 112 cuts the sample, the sample can be moved to a collection position by the movement of the first follower 111, and then pushed out of the die 112 by the ejection plate 114. In a specific arrangement, the ejection plate 114 is located inside the die 112 and can be used to push the sample in the die 112 out. The ejection plate 114 can move relative to the die 112 to change the size of the space in the die 112 for accommodating the sample. When the die 112 cuts the rubber, the ejection plate 114 is located inside the die 112 and away from the blade of the die 112 (the end of the die 112 away from the first follower 111) so that the die 112 has a large enough space to accommodate the sample. When ejection is needed, the ejection plate 114 moves towards the blade of the die 112 so that the ejection plate 114 can push the sample out of the die 112 to achieve ejection of the sample.

[0031] It should be understood that, in the arrangement of the pin 113 and the ejection plate 114, both the pin 113 and the ejection plate 114 are located inside the die 112, but the ejection plate 114 avoids the pin 113 so that there is no interference between them.

[0032] Referring to Figure 3 , Figure 3 A structural diagram of the push-in assembly 120 is shown. The push-in assembly 120 includes a second follower 121, a support plate 122, and a top plate 123. The support plate 122 is used to cooperate with the die 112, and the rubber can be supported by the top plate 123 when the die 112 cuts the rubber. The top plate 123 is used to push the sample into the die 112 to facilitate the separation between the sample and the rubber and improve the effect of extracting the sample. The second follower 121 supports the support structure of the support plate 122 and the top plate 123, which can move synchronously with the rubber to ensure that the position of the support plate 122 relative to the rubber is fixed.

[0033] In a specific arrangement, the support plate 122 is fixed to the second follower 121, and the top plate 123 can slide relative to the support plate 122. The sliding direction of the top plate 123 is along the height direction of the rack 200. When the top plate 123 is not raised, the top plate 123 supports the rubber synchronously with the support plate 122. When the top plate 123 is raised, it can separate the sample cut by the die 112 from the rubber so that it can be put into the die 112. It should be understood that, in a specific arrangement, the top plate 123 avoids the pin 113 to avoid interference between the top plate 123 and the pin 113.

[0034] In the specific sampling, the controller can be used for controlling the cutting assembly and the pushing assembly in any sampling assembly to sample, or simultaneously controlling the cutting assembly and the pushing assembly in at least part of the sampling assemblies in at least two sampling assemblies to sample simultaneously or alternately. For example, when one sampling assembly is controlled to sample, the controller controls the cutting assembly and the pushing assembly in the sampling assembly to act simultaneously to sample the rubber. When the sampling needs to be alternated, the controller can control part or all of the sampling assemblies to sample alternately. When the sampling needs to be simultaneously, the controller can control part or all of the sampling assemblies to sample simultaneously. It should be understood that when the controller controls the above-mentioned at least two sampling assemblies to sample in different ways, the signal for controlling the sampling assembly to act is achieved, and the controller can control the different sampling assemblies by using the conventional control logic in the prior art. The improvement of the control logic is not involved in the embodiments of the present application, and only the controller and the arrangement of the at least two sampling assemblies for different sampling are increased.

[0035] As can be seen from the above description, the sampling device provided by the embodiments of the present application can control at least two sampling assemblies to sample individually, or simultaneously, or alternately by the controller, so as to realize different sampling modes and meet different sampling requirements, and the sampling efficiency can be improved. In addition, in each sampling assembly 100, the cooperation of the pin 113 and the top plate 123 can improve the effect of the sample piece being separated from the rubber. At the same time, the sample piece can be taken out more conveniently by the mold head.

[0036] With reference to the above description, Figure 2 As shown in the figure, the first follower 111 can be connected with the rack 200 through a transmission mechanism to realize the synchronous movement of the first follower 111 and the rubber. For example, the rack 200 can be provided with a first track, and the first follower 111 can be slidably assembled on the first track, and the extension direction of the first track is along the transmission direction of the rubber.

[0037] The first follower seat 111 is retractable along the height direction of the rack 200 to drive the cutter die 112 to cut the rubber. For example, the first follower seat 111 comprises a support seat 1111 and a moving seat 1112. The support seat 1111 is synchronously movable with the rubber, i.e. the support seat 1111 is in sliding connection with the first track. The moving seat 1112 is used to fix the cutter die 112 and the pin 113. The moving seat 1112 is retractable along the height direction of the rack 200 relative to the support seat 1111 to drive the cutter die 112 to cut the rubber. For example, the moving seat 1112 is connected with the support seat 1111 through a driving component, which is used to drive the moving seat 1112 to retract relative to the support seat 1111. The driving component can be a linear motor, a driving hydraulic cylinder or other linear driving mechanism. The linear motor, the driving hydraulic cylinder or other linear driving mechanism can drive the moving seat 1112 to move relative to the support seat 1111.

[0038] Referring to Figure 2 and Figure 4 , Figure 4 The structure of the cutter die 112 is shown in the figure. The cutter die 112 is a cylindrical structure, which is internally provided with the pin 113 and the ejection plate 114. The pin 113 is fixed on the moving seat 1112, and the ejection plate 114 is located in the cutter die 112 and is provided with an escape hole 1141 corresponding to each pin 113. When the ejection plate 114 moves relative to the cutter die 112, the ejection plate 114 can avoid the pin 113.

[0039] When the pin 113 is arranged, the tip of the pin 113 is exposed outside the cutter die 112. When the cutter die 112 cuts the rubber, the pin 113 can first fix the part of the rubber to be a sample. When the cutter die 112 descends and cuts the sample, the pin 113 can be stably inserted into the sample, thereby ensuring the stability of the connection between the sample and the pin 113. When the above-mentioned method is used, the pin 113 can first fix the rubber, thereby ensuring the relative fixation between the cutter die 112 and the rubber (in the transmission direction of the rubber) when the cutter die 112 cuts, thereby ensuring the cutting effect.

[0040] When the ejection plate 114 moves relative to the cutter die 112, the ejection plate 114 can be driven by a first driving mechanism, which is fixed on the first follower seat 111 and is used to drive the ejection plate 114 to move relative to the cutter die 112. For example, the first driving mechanism is fixed on the moving seat 1112, and the first driving mechanism can be a driving hydraulic cylinder, a driving air cylinder, a linear motor or other common driving mechanism. When ejection is needed, the ejection plate 114 can be moved by the first driving mechanism, thereby pushing the sample out of the cutter die 112.

[0041] Referring to Figure 3The top plate 123 in the top-in assembly 120 can be driven by a driving mechanism when being lifted. In an example, the top-in assembly 120 further comprises a second driving mechanism fixed on the support plate 122 and used to drive the top plate 123 to lift. The second driving mechanism can be a linear motor, a driving hydraulic cylinder or other common driving mechanism. In use, the second driving mechanism is fixed on the side of the support plate 122 away from the rubber, and drives the top plate 123 to lift or lower when being driven.

[0042] In an optional solution, the top plate 123 comprises a ring-shaped plate 1231, and cross-shaped rib plates 1232 are arranged in the ring-shaped plate 1231; the output end of the driving mechanism is fixedly connected with the cross position of the rib plates 1232. In this structure, the weight of the top plate 123 can be reduced while the structural strength of the top plate 123 is ensured, and the second driving mechanism is facilitated to drive.

[0043] In addition, a plurality of through holes 1233 are arranged on the top plate 123, and the through holes 1233 correspond to the pins 113 one by one to prevent interference between the top plate 123 and the pins 113 when the top plate 123 is lifted. In addition, the pins 113 can also guide the sample sheet to enter the die 112 smoothly when the top plate 123 is lifted.

[0044] In an optional solution, the shape of the top plate 123 matches the shape of the inner cavity of the die 112, and the top plate 123 can be nested in the inner cavity of the die 112. In this way, on the one hand, the top plate 123 can support the edge of the sample sheet when being lifted, facilitating the sample sheet to separate from the rubber, and on the other hand, the top plate 123 can be easily put into the die 112 to send the sample sheet into the die 112.

[0045] To facilitate understanding of the sampling device provided by the embodiments of the present application, the working process of the two sampling assemblies 100 will be described in detail below. To facilitate understanding, the positions of the two sampling assemblies 100 are named as No. 1 station and No. 2 station. The sampling device provided by the embodiments of the present application can execute only No. 1 station action, only No. 2 station action and No. 1 and No. 2 station action simultaneously according to different sampling commands.

[0046] When the sampling device receives the sampling command of the first station, the controller controls the cutting assembly 110 in the sampling assembly 100 of the first station to perform downward action to 20mm away from the rubber surface, then the first and second follow-up seats 111 and 121 start to follow the rubber transmission movement, and the cutting assembly 110 performs downward cutting (interference) by torque control, and the cutting assembly 110 falls to the bottom during the follow-up process, the second driving mechanism of the top-in assembly 120 performs the lifting action to fix the sample in the cutter die 112, then the cutting assembly 110 is separated, the first and second follow-up seats 111 and 121 return to the original home position, and the sampling work of the sample is completed. Then the material taking transmission assembly can be moved below the cutting assembly 110 to take the material, and after the material taking is completed, the material taking transmission assembly moves to the outside of the equipment to open the rubber grabbing head and drop the rubber into the material taking position, and the sampling action is completed.

[0047] Similarly, the working process of the sampling assembly 100 of the second station is the same as the sampling mode of the first and second stations, and will not be described in detail here.

Therefore, any omission, modification, equivalent replacement, improvement, etc. made in the spirit and principle of one or more embodiments of the present specification should be included in the protection scope of the present disclosure.
