Description

Technical Field

[0001] The present invention relates to the technical field of cross-linking agent production equipment, and more specifically to a sample acquisition device for cross-linking agent processing. Background Art

[0002] Crosslinkers are a class of chemicals that are used to enhance the structure and properties of polymers. Through crosslinking reactions with polymer chains, crosslinkers can form a three-dimensional network structure in polymers, thereby improving their physical and chemical properties. Crosslinkers need to be stirred during their production.

[0003] In the process of stirring the crosslinking agent, in order to prevent the crosslinking agent from being insufficiently stirred, resulting in differences in the concentration of the crosslinking agent, which seriously interferes with the use effect of the crosslinking agent, sampling and testing are required during the stirring process. In the prior art, the crosslinking agent is generally directly extracted from the stirring device for testing during the testing process. However, in the actual stirring process, the stirring effect of the crosslinking agent at different heights may be different, resulting in different concentrations of the crosslinking agent at different heights. If the crosslinking agent at a certain height is simply tested, there may be a large error; In view of the above problems, some solutions have been provided in the prior art. For example, the Chinese utility model patent with announcement number CN217962499U discloses a stirring device for cross-linking agent production. The device is provided with multiple detection components, which can sample and detect the cross-linking agents at different heights respectively, thereby solving the problem of inaccurate detection caused by different stirring degrees of the cross-linking agents at different heights. Although the prior art can improve the detection accuracy to a certain extent, it still has certain limitations. First, after the sampling is completed, the prior art still needs to take the cross-linking agent out of the feeder, which seriously affects the sampling efficiency. After the user takes the cross-linking agent out of the feeder, the cross-linking agent will remain on the inner wall of the feeder, which will affect the next sampling, and then seriously affect the accuracy of the sample. Summary of the invention

[0004] In view of the problems existing in the prior art, the object of the present invention is to provide a sample acquisition device for cross-linking agent processing, which can achieve the purpose of improving the accuracy of the sample.

[0007] Furthermore, the blocking assembly includes a sealing plate slidably mounted on the top wall of the sampling box, a linkage plate fixedly mounted on the sealing plate, an elastic pad installed between the linkage plate and the side wall of the sampling box, an installation groove is opened on the sealing plate, and a sealing gasket is arranged in the installation groove.

[0008] Furthermore, a sealing cavity is provided on the sealing gasket, a first cavity is provided on the elastic gasket, a first air pipe is inserted into the sealing cavity, a connecting component is provided on the linkage plate, and the first air pipe is connected with the first cavity through the connecting component, and a one-way valve whose output end is connected with the first cavity is inserted into the sealing cavity.

[0009] Furthermore, the connecting component includes a horizontal groove opened on the linkage plate, a sealing rod is slidably installed in the horizontal groove, a first spring is fixedly installed between the side wall of the sealing rod and the horizontal groove, and a connecting hole connected to the first air pipe is opened on the sealing rod.

[0010] Furthermore, elastic air bags are evenly installed between the slide groove and the vertical rod, a vertical groove is opened on the installation box, a fixed rod is slidably installed in the vertical groove, and the top wall of the fixed rod is an inclined surface, a fixed groove that slides with the fixed rod is opened on the bottom wall of the sampling box, a second air pipe connected to the vertical groove is inserted on the elastic air bag, and a linkage component that cooperates with the fixed rod is provided on the sampling box.

[0011] Furthermore, the linkage assembly includes a rotating rod rotatably mounted on the sampling box, a horizontal rod is evenly fixedly mounted on the rotating rod, a rotating groove is provided on the rotating rod, and a protrusion that slidably cooperates with the rotating groove is fixedly mounted on the vertical rod.

[0012] Furthermore, the mounting box is provided with a horizontal groove, a limit rod is slidably installed in the horizontal groove, a third spring is fixedly installed between the limit rod and the horizontal groove, a first limit groove is provided on the sampling block, a linkage groove is provided on the sampling block, a linkage rod is slidably installed in the linkage groove, a reset spring is fixedly installed between the linkage rod and the linkage groove, a first magnet is embedded in the limit rod, and a second magnet that attracts the first magnet is embedded in the linkage rod.

[0013] Furthermore, a plug plate is detachably installed in the feeding port.

[0014] Furthermore, the surface of the convex block is a smooth mirror surface.

[0015] Furthermore, a push rod is detachably mounted on the sampling box.

[0016] Compared with the prior art, the present invention has the following beneficial effects: (1) This scheme provides a sampling box. When sampling, the user can drive the sampling box into the mixing drum through the vertical rod and the installation box to take samples. After the sampling is completed, the user drives the sampling box to move out of the mixing drum through the vertical rod and the installation box, and takes out the sampling box containing the cross-linking agent and completes the sampling, thereby avoiding the cross-linking agent from remaining and affecting the accuracy of the next sampling. At the same time, when taking out the sampling box, the elastic pad stretches and drives the sealing plate to seal the sampling box through the linkage plate, thereby avoiding the sample from spilling, and effectively preventing the sample from being oxidized due to long-term contact with the air, which affects the accuracy of the sample, thereby improving the accuracy of the sample; (2) In this solution, a sealing pad is provided. During the contraction of the elastic pad, the airflow in the first cavity flows into the sealing cavity through the first air pipe and the connecting component, and the gas pressure in the sealing cavity is increased. Then, the sealing pad expands under the action of the gas pressure. The expanded sealing pad can fit tightly with the top wall of the sampling box, thereby improving the sealing performance of the sampling box and further preventing the sample from being oxidized, thereby further improving the sample accuracy. (3) This scheme sets a connecting component. When the sealing rod moves toward the sampling box, it gradually contacts the side wall of the sampling box. Then, the side wall of the sampling box pushes the sealing rod to move along the horizontal groove and squeezes the first spring. At the same time, the connecting hole is driven to move during the movement of the sealing rod. After the sealing plate seals the sampling box, the sealing rod drives the connecting hole to connect with the first air pipe. At this time, the airflow in the first cavity can flow into the sealing cavity through the connecting hole and the first air pipe, and cause the sealing gasket to expand. That is, the sealing gasket will expand only after the sealing plate seals the sampling box. This prevents the sealing gasket from expanding prematurely and affecting the normal sealing of the sampling box by the sealing plate, thereby improving the sealing effect of the sampling box.

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0020] See also Figures 1 to 7 A sample acquisition device for cross-linking agent processing, comprising a workbench 1, a mixing drum 2 is fixedly mounted on the top wall of the workbench 1, a motor 3 is fixedly mounted on the top wall of the mixing drum 2, a mixing rod 4 is fixedly mounted on the output end of the motor 3, a feeding port is opened on the top wall of the mixing drum 2, a discharge valve 5 is inserted on the bottom wall of the mixing drum 2, and a sampling component 6 is provided on the mixing drum 2; The sampling assembly 6 includes a sampling block 601 fixedly mounted on the side wall of the mixing drum 2, a slide groove is provided on the sampling block 601, a vertical rod 602 is slidably mounted in the slide groove, a mounting box 603 is fixedly mounted on the vertical rod 602, a sampling port slidably matched with the mounting box 603 is provided on the side wall of the mixing drum 2, a sampling box 604 is slidably mounted in the mounting box 603, a connecting port 605 matched with the sampling box 604 is provided on the sampling block 601, and a blocking assembly 7 is provided on the sampling box 604.

[0021] The blocking assembly 7 includes a sealing plate 701 slidably mounted on the top wall of the sampling box 604, a linkage plate 702 is fixedly mounted on the sealing plate 701, an elastic pad 703 is installed between the linkage plate 702 and the side wall of the sampling box 604, and a mounting groove is opened on the sealing plate 701, and a sealing pad 704 is arranged in the mounting groove.

[0022] When in use, the user can first put the cross-linking agent raw material into the mixing drum 2 through the feeding port, and then the stirring rod 4 can be driven by the motor 3 to rotate and stir the cross-linking agent raw material. After stirring for a period of time, the user can push the vertical rod 602 to move along the slide groove. During the movement of the vertical rod 602, the sampling box 604 is driven to enter the mixing drum 2 through the installation box 603, and then the cross-linking agent mixed in the mixing drum 2 will enter the sampling box 604. After the cross-linking agent enters the sampling box 604, the user pushes the vertical rod 602 to the raw material mixing drum 2. The sampling box 604 moves in the direction of the vertical rod 602, and is driven by the mounting box 603 to move out of the mixing drum 2 during the movement of the vertical rod 602. The user can then take out the sampling box 604 containing the cross-linking agent and complete the sampling. After the sampling box 604 is taken out, the user can put in a new sampling box 604, thereby avoiding the cross-linking agent from remaining and affecting the accuracy of the next sampling, thereby improving the accuracy of the sample. In the sampling process, the user only needs to push the vertical slot 902 rod to complete the sampling, thereby eliminating the need for the user to perform separate sampling each time.

[0023] When the user pushes the sampling box 604 into the sampling box 604 through the connecting port 605, the sampling box 604 drives the sealing plate 701 to gradually contact the side wall of the slide groove, and then the side wall of the slide groove applies a thrust to the sealing plate 701, and causes the sealing plate 701 to move along the top wall of the sampling box 604. During the movement of the sealing plate 701, it drives the interlocking plate 702 to move. At this time, the elastic pad 703 is squeezed and has a tendency to recover. Then, when the sampling is completed and the user takes the sampling box 604 out of the installation box 603, the elastic pad 703 stretches and drives the interlocking plate 702 to move toward the sampling box 604. During the movement of the interlocking plate 702, it drives the sealing plate 701 to move along the top wall of the sampling box 604 again and seals the sampling box 604, thereby avoiding sample spillage and effectively preventing the sample from being oxidized by long-term contact with air, thereby affecting the accuracy of the sample, thereby further improving the accuracy of the sample.

[0024] like Figure 2 , Figure 3 , Figure 4 As shown in the figure, a sealing cavity 801 is opened on the sealing pad 704, a first cavity 802 is opened on the elastic pad 703, a first air pipe 803 is inserted into the sealing cavity 801, a connecting component 805 is provided on the linkage plate 702, and the first air pipe 803 is connected with the first cavity 802 through the connecting component 805, and a one-way valve 804 whose output end is connected with the first cavity 802 is inserted into the sealing cavity 801.

[0025] The connecting component 805 includes a horizontal groove 8051 opened on the linkage plate 702, a sealing rod 8052 is slidably installed in the horizontal groove 8051, a first spring 8053 is fixedly installed between the side wall of the sealing rod 8052 and the horizontal groove 8051, and a connecting hole 8054 connected to the first air pipe 803 is opened on the sealing rod 8052.

[0026] By adopting the above technical solution, during the contraction of the elastic pad 703, the airflow in the first cavity 802 flows into the sealed cavity 801 through the first air pipe 803 and the connecting component 805, and the gas pressure in the sealed cavity 801 increases, and then the sealing pad 704 expands under the action of the gas pressure. The expanded sealing pad 704 can fit tightly with the top wall of the sampling box 604, thereby improving the sealing of the sampling box 604, further preventing the sample from being oxidized, and further improving the sample accuracy.

[0027] When the user pushes the sampling box 604 into the installation box 603, the sealing plate 701 stretches the elastic pad 703 through the linkage plate 702. At this time, the pressure in the first cavity 802 decreases, and then the sealing pad 704 gradually shrinks, driving the airflow in the sealing cavity 801 to flow into the first cavity 802 through the one-way valve 804, thereby preparing for work again.

[0028] During the contraction of the elastic pad 703, the airflow in the first cavity 802 tends to flow to the outside. Then, during the contraction of the elastic pad 703 and the movement of the linkage plate 702, the linkage plate 702 drives the sealing rod 8052 to move toward the sampling box 604. During the movement of the sealing rod 8052 toward the sampling box 604, the sealing rod 8052 gradually contacts the side wall of the sampling box 604. Then, the side wall of the sampling box 604 pushes the sealing rod 8052 to move along the horizontal groove 8051 and squeeze the first spring 8053. At the same time, during the movement of the sealing rod 8052, the connecting hole 8052 is driven to move. 4 moves, and after the sealing plate 701 seals the sampling box 604, the sealing rod 8052 drives the connecting hole 8054 to communicate with the first air pipe 803. At this time, the airflow in the first cavity 802 can flow into the sealing cavity 801 through the connecting hole 8054 and the first air pipe 803, and make the sealing gasket 704 expand, that is, the sealing gasket 704 will expand only after the sealing plate 701 seals the sampling box 604, thereby avoiding the sealing gasket 704 from expanding in advance and affecting the normal sealing of the sampling box 604 by the sealing plate 701, thereby improving the sealing effect of the sampling box 604.

[0029] When the sampling box 604 enters the installation box 603, the sealing plate 701 drives the linkage plate 702 to move toward the raw material sampling box 604. At this time, the first spring 8053 stretches and drives the sealing rod 8052 to move. During the movement of the sealing rod 8052, the connecting hole 8054 is driven to break contact with the first air pipe 803, thereby preparing for work again.

[0030] like Figure 3 , Figure 5 , Figure 6 As shown, an elastic airbag 901 is evenly installed between the slide groove and the vertical rod 602, a vertical groove 902 is opened on the installation box 603, a fixed rod 903 is slidably installed in the vertical groove 902, and the top wall of the fixed rod 903 is an inclined surface, a fixed groove 904 that slides with the fixed rod 903 is opened on the bottom wall of the sampling box 604, a second air pipe 905 that is connected to the vertical groove 902 is inserted on the elastic airbag 901, and a linkage component 10 that cooperates with the fixed rod 903 is provided on the sampling box 604.

[0031] The linkage assembly 10 includes a rotating rod 104 rotatably mounted on the sampling box 604 , a horizontal rod 101 is evenly fixedly mounted on the rotating rod 104 , a rotating groove 102 is opened on the rotating rod 104 , and a protrusion 103 that slidably cooperates with the rotating groove 102 is fixedly mounted on the vertical rod 602 .

[0032] By adopting the above technical solution, in the initial state, the elastic airbag 901 is in a free extension state. When the user pushes the sampling box 604 into the installation box 603, the side wall of the sampling box 604 gradually contacts the inclined surface of the fixing rod 903 and applies a thrust to the inclined surface of the fixing rod 903. Then, under the action of the thrust, the fixing rod 903 moves downward. At this time, the airflow in the vertical groove 902 is squeezed and flows into the elastic airbag 901 through the second air pipe 905. At this time, the gas pressure in the elastic airbag 901 increases, and the sampling box 604 is in contact with the inclined surface of the fixing rod 903. 04 drives the fixed groove 904 to gradually contact with the fixed rod 903 during the movement, and then the excess airflow in the elastic airbag 901 flows to the vertical groove 902 through the second air pipe 905 under the action of pressure, and drives the fixed rod 903 to be inserted into the fixed groove 904, and then the sampling box 604 is fixed with the cooperation of the fixed rod 903 and the fixed groove 904, thereby avoiding the sampling box 604 from being out of contact with the installation box 603 during the sampling process, causing the cross-linking agent to be lost through the sampling port, thereby improving the sampling stability.

[0033] When sampling is completed, the user can stop applying thrust to the vertical rod 602. At this time, the elastic airbag 901 stretches and drives the vertical rod 602 to reset. During the resetting process of the vertical rod 602, the sampling box 604 can be driven to disengage from the sampling port through the installation box 603. Then, when the sampling box 604 needs to be taken out, the user can pull the vertical rod 602 out of the slide slot. At this time, the elastic airbag 901 is stretched, and then the elastic airbag 901 inhales air from the vertical slot 902 through the second air pipe 905, and creates a negative pressure in the vertical slot 902. Then, under the action of pressure, the fixed rod 903 moves downward along the vertical slot 902, and gradually disengages from the sampling box 604 during the movement of the fixed rod 903. At this time, the user can remove the sampling box 604.

[0034] When the user pushes the vertical rod 602 to squeeze the elastic airbag 901 along the slide groove, the airflow in the elastic airbag 901 flows to the vertical groove 902 through the second air pipe 905, and drives the fixed rod 903 to move upward along the vertical groove 902, and drives the protrusion 103 to move upward in the process of the fixed rod 903 moving, and moves along the rotating groove 102 in the process of the protrusion 103 moving upward, and then drives the rotating rod 104 to rotate along the rotating groove 102 in the process of the protrusion 103 moving along the rotating groove 102, and drives the horizontal rod 101 to rotate in the process of the rotating rod 104, and then the cross-linking agent in the sampling box 604 can be stirred in the process of the horizontal rod 101 rotating, so that the cross-linking agent in the sampling box 604 can be fully mixed, thereby improving the accuracy of the sample.

[0035] like Figure 5 , Figure 7 As shown, the installation box 603 is provided with a horizontal groove 8051, a limiting rod 111 is slidably installed in the horizontal groove 8051, a third spring 112 is fixedly installed between the limiting rod 111 and the horizontal groove 8051, a first limiting groove 113 is provided on the sampling block 601, a linkage groove is provided on the sampling block 601, a linkage rod 114 is slidably installed in the linkage groove, a reset spring 115 is fixedly installed between the linkage rod 114 and the linkage groove, a first magnet 116 is embedded in the limiting rod 111, and a second magnet 117 that attracts the first magnet 116 is embedded in the linkage rod 114.

[0036] By adopting the above technical solution, in the initial state, the third spring 112 is in a free extension state, at which time the limiting rod 111 contacts the first limiting groove 113, that is, at this time the user cannot push the installation box 603 into the mixing drum 2, and then in the process of the user pushing the sampling box 604 into the installation box 603, the sampling box 604 gradually contacts the connecting rod 114 and applies a thrust to the connecting rod 114, and then under the action of the thrust, the connecting rod 114 moves along the connecting groove and squeezes the reset spring 115, and in the process of the movement of the connecting rod 114, the second magnet 117 gradually approaches the first magnet 116, and at this time the first magnet 116 is subjected to an increasingly greater suction force, and when the side wall of the sampling box 604 is attached to the side wall of the installation box 603 After closing, the suction force between the first magnet 116 and the second magnet 117 reaches a maximum. At this time, under the action of the suction force, the first magnet 116 drives the limiting rod 111 to approach the second magnet 117 and squeeze the third spring 112. During the movement of the limiting rod 111, it gradually loses contact with the first limiting groove 113. At this time, the user can drive the installation box 603 to move toward the mixing drum 2 through the vertical rod 602, that is, only when there is a sampling box 604 in each installation box 603, the user can drive the sampling box 604 into the mixing drum 2 for sampling through the vertical rod 602 and the installation box 603, thereby avoiding the loss of cross-linking agent due to forgetting to put the sampling box 604 in the installation box 603, and further improving the stability of the sampling equipment operation.

[0037] like Figure 2 As shown, a plug plate 12 is detachably installed in the feeding port.

[0038] By adopting the above technical solution, after the user completes adding the raw materials through the feeding port, the user can install the plug plate 12 in the feeding port and seal the feeding port to prevent air from entering the mixing drum 2 through the feeding port and causing the cross-linking agent to be oxidized.

[0039] like Figure 6 As shown, the surface of the bump 103 is a smooth mirror surface.

[0040] By adopting the above technical solution, when the protrusion 103 drives the rotating rod 104 to rotate through the rotating groove 102, friction will occur between the protrusion 103 and the rotating groove 102. By making the surface of the protrusion 103 a smooth mirror surface, the friction between the protrusion 103 and the rotating groove 102 can be reduced, thereby ensuring that the protrusion 103 drives the rotating rod 104 to rotate through the rotating groove 102.

[0041] like Figure 2 As shown, a push rod 13 is detachably mounted on the sampling box 604 .

[0042] By adopting the above technical solution, when the user installs the sampling box 604 in the installation box 603, the user can push the sampling box 604 into the installation box 603 through the push rod 13, and when the sampling box 604 needs to be taken out, the user can pull the sampling box 604 outward through the push rod 13 and take the sampling box 604 out of the installation box 603, which makes it easy to take out and put in the sampling box 604.

[0043] Instructions for use: When in use, the user can first put the cross-linking agent raw material into the mixing drum 2 through the feeding port, and then the motor 3 can be used to drive the stirring rod 4 to rotate and stir the cross-linking agent raw material. After stirring for a period of time, the user can push the vertical rod 602 to move along the slide groove. During the movement of the vertical rod 602, the sampling box 604 is driven into the mixing drum 2 through the installation box 603, and then the mixed cross-linking agent in the mixing drum 2 will enter the sampling box 604. After the cross-linking agent enters the sampling box 604, the user pushes the vertical rod 602 to the raw material. The mixing drum 2 moves in the direction of the mixing drum 2. During the movement of the vertical rod 602, the sampling box 604 is driven to move out of the mixing drum 2 through the installation box 603. Then the user can take out the sampling box 604 containing the cross-linking agent and complete the sampling. After the sampling box 604 is taken out, the user can put in a new sampling box 604. At the same time, when the sampling box 604 is taken out, the blocking component 7 can block the sampling box 604 to avoid the sample from spilling and effectively prevent the sample from being oxidized by long-term contact with the air. At the same time, by providing a sealing gasket 704 with a sealing cavity 801, During the contraction of the elastic pad 703, the sealing pad 704 expands, and the expanded sealing pad 704 can fit tightly with the top wall of the sampling box 604, thereby improving the sealing performance of the sampling box 604. The setting of the connecting component 805 can make the sealing pad 704 expand only after the sealing plate 701 seals the sampling box 604, thereby preventing the sealing pad 704 from expanding in advance and affecting the normal sealing of the sampling box 604 by the sealing plate 701; then the setting of the fixing rod 903 can fix the sampling box 604 to avoid sampling during the sampling process. The box 604 is out of contact with the installation box 603, causing the cross-linking agent to be lost through the sampling port; and in the process of the fixing rod 903 being inserted into the fixing groove 904, the cross-linking agent in the sampling box 604 can also be stirred by the linkage assembly 10; in addition, the setting of the limit rod 111 makes it possible for the user to drive the sampling box 604 into the mixing drum 2 for sampling only when there is a sampling box 604 in each installation box 603, thereby avoiding the loss of the cross-linking agent due to forgetting to put the sampling box 604 into the installation box 603.

[0044] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
