[0023] 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.

[0025] To facilitate understanding of the ejection device provided in this application embodiment, its application scenario is first described. The ejection device provided in this application embodiment is used in rubber sampling. In the prior art, rubber sampling requires stopping the rubber transport, which affects the operation of the equipment. Therefore, this application embodiment provides an ejection device that works in conjunction with a die to sample rubber, improving the sampling effect.
[0026] During rubber sampling, the rubber is cut using a die to form a sample. In a specific setup, the sampling device includes a die that moves synchronously with the rubber, moving in a direction perpendicular to the rubber's movement to cut the sample. Specifically, the die has a cylindrical structure, and the sample is retained within it after cutting. However, when the die cuts the rubber, the rubber is suspended in the air, resulting in poor cutting performance. Furthermore, the sample tends to adhere to the rubber during cutting, and it cannot move with the die when it leaves the rubber.
[0027] Therefore, the sampling device provided in this application embodiment also includes an ejection device, which is used to eject the sample into the die. The ejection device will be described in detail below with reference to specific examples.
[0028] refer to Figure 1 As shown, Figure 1 A cross-sectional view of the ejection device provided in an embodiment of this application is shown; Figure 2This diagram illustrates the cooperation between the support base 10 and the top plate 20 according to an embodiment of this application. The ejection device includes a base 30 and a support base 10. The base 30 serves as a support structure to support the support base 10, and the support base 10 is slidably mounted on the base 30. The sliding direction of the support base 10 is along the transmission direction of the rubber, i.e., along the movement direction of the rubber. When the support base 10 slides, the support base 10 and the rubber can move synchronously to ensure the relative fixation of the support base 10 and the rubber.
[0029] The support base 10 is located below the rubber, and the side of the support base 10 facing away from the base 30 is a support surface used to support the rubber. When the die cuts the rubber, the support base 10 can support the rubber from below, thereby providing support force to the rubber and ensuring that the die can cut stably during the cutting process.
[0030] In addition, the ejection device also includes a top plate 20, which is used to eject the sample. In a specific configuration, the top plate 20 is movable relative to the support base 10, and the direction of movement of the top plate 20 is perpendicular to the sliding direction of the rubber. In actual use, the sample is ejected into the die by the top plate 20, facilitating the sample's entry into the die. Furthermore, during ejection, the top plate 20 can pull apart the adhesive portion between the sample and the rubber, facilitating the sample's entry into the die. It should be understood that the size of the top plate 20 is smaller than the size of the die's inner cavity to ensure that the sample can enter the die when the top plate 20 ejects it. Moreover, the top plate 20 is not interfered with by the rubber during the ejection process.
[0031] When the top plate 20 moves, when it is in the first set position, it is hidden inside the support base 10 and does not protrude outwards. That is, along the direction perpendicular to the rubber transport, the top plate 20 is lower than the support surface of the support plate. In this state, the die is cutting the rubber to form a sample. At this time, the support surface of the support base 10 remains flat, and the top plate 20 will not push the rubber up, ensuring the cutting effect of the die. When the top plate 20 is in the second set position, it protrudes outwards from the support base 10 and is used to push the sample into the die. In this state, the top plate 20 rises upwards and can push the sample into the die.
[0032] In the specific driving of the top plate 20, the ejection mechanism also includes a drive mechanism 40, which is used to drive the top plate 20 to move. For example, the drive mechanism 40 can be a drive cylinder, a drive hydraulic cylinder, or other linear drive mechanism 40, as long as it can drive the top plate 20 to rise and fall in a direction perpendicular to the rubber transmission direction.
[0033] As can be seen from the above description, the ejection device provided in this application embodiment uses a support base 10 that moves along the direction of rubber transmission and supports the rubber. Therefore, when cutting the rubber sampling piece, the stability of the rubber can be maintained, improving the sampling effect. In addition, the ejection device also includes a top plate 20, which is used to lift the cut sample piece from the rubber, thereby facilitating sampling.
[0034] Continue to refer to Figure 2 As shown, the top plate 20 provided in this embodiment includes an annular plate 22, within which cross-shaped ribs 21 are disposed; the output end of the drive mechanism 40 is fixedly connected to the intersection position of the ribs 21. That is, the top plate 20 adopts a hollow structure, thereby reducing the weight of the top plate 20. Furthermore, the cooperation between the annular plate 22 and the ribs 21 also ensures the structural strength of the top plate 20. The annular plate 22 of the top plate 20 is used to push out the edge of the sample, thereby facilitating the separation of the sample from the rubber.
[0035] Please refer to the above. Figure 1 The support base 10 is provided with a receiving groove, and when the top plate 20 is in the first predetermined position, the top plate 20 is located in the receiving groove. When the above structure is adopted, the top plate 20 is hidden by the receiving groove to ensure that no protrusion structure is formed on the support surface when the top plate 20 is not in use, thus ensuring the effect of the die when cutting rubber.
[0036] In one specific implementation, the support base 10 includes an upper support plate 11 and a lower support plate 13, and two vertical plates 12 connecting the upper support plate 11 and the lower support plate 13. A receiving groove is provided on the upper support plate 11, while the lower support plate 13 is slidably connected to the base 30. When the drive mechanism 40 is provided, the drive mechanism 40 is fixed to the upper support plate 11, and the drive end of the drive mechanism 40 passes through the upper support plate 11 and is fixedly connected to the top plate 20. With the above mechanism, the drive mechanism 40 is located between the upper support plate 11 and the lower support plate 13, and is fixedly connected to the upper support plate 11. On the one hand, the two vertical plates 12 protect the drive mechanism 40. On the other hand, it reduces the distance between the drive mechanism 40 and the top plate 20, allowing the drive mechanism 40 to drive the top plate 20 with a shorter extension stroke.
[0037] In the specific configuration, the upper support plate 11 has a groove on the side facing the lower support plate 13, and the drive mechanism 40 is fixed in the groove. The use of the groove to cooperate with the drive mechanism 40 facilitates the positioning of the drive mechanism 40, makes installation easier, and also reduces the distance between the drive mechanism 40 and the top plate 20.
[0038] In another feasible embodiment, the upper support plate 11 includes a first support plate and a second support plate 112; the first support plate and the second support plate 112 are fixedly connected, with the second support plate 112 located close to the lower support plate 13. In a specific configuration, the first support plate and the second support plate 112 are stacked perpendicular to the direction of rubber movement. They can be fixedly connected by bolts or other connecting components. Furthermore, the first support plate has a receiving groove, and the second support plate 112 has a recess. When using the above structure, the first support plate and the second support plate 112 can be made of relatively thin steel plates, which are then assembled into an upper support plate 11.
[0039] When the support base 10 and the base 30 are in sliding engagement, two slide blocks 14 are provided on the lower support plate 13, each slide block 14 having a sliding groove, and the base 30 has a slide rail 31 that mates with the two sliding grooves one by one. The sliding direction of the support base 10 is ensured by the engagement of the sliding grooves and the slide rails 31. In one feasible embodiment, the drive mechanism 40 is located between the two sliding grooves. This allows the drive mechanism 40 to be supported by the two slide rails 31 when applying force, ensuring the stability of the top plate 20 when lifting the sample.
[0040] For example, the lower support plate 13 is provided with two stepped surfaces 131, and the two slides 14 are assembled one-to-one on the two stepped surfaces 131. The slides 14 are positioned by the stepped surfaces 131, which ensures the accuracy of their assembly and the cooperation effect with the slide rail 31.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of one or more embodiments of this specification should be included within the scope of protection of this disclosure.
[0042] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
