Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing technology, and in particular to a material feed pipe structure. Background Technology

[0002] With the continued prosperity of the motorcycle, tricycle, and automobile manufacturing industries, the production quality and efficiency of oil-based coatings are crucial as key materials for improving product appearance, enhancing corrosion resistance, and extending service life. Currently, the production process of oil-based coatings often involves directly weighing the materials in the mixing tank to determine their weight. Specifically, a weighing sensor is installed below the mixing tank to detect the total weight of the tank and its contents, thus determining the weight of the added material. This weighing method enables the monitoring and control of material weight, providing data support for material proportioning during the production process.

[0003] However, in the existing method, the material feed pipe is directly installed on the mixing tank, which affects the weighing accuracy. Utility Model Content

[0004] The purpose of this utility model is to provide a material feed pipe structure, which aims to solve the technical problem in the prior art that the weighing accuracy is affected because the material feed pipe is directly installed on the mixing tank.

[0005] To achieve the above objectives, this utility model employs a material feed pipe structure, comprising a connecting pipe, an assembly assembly, an insertion pipe, and a sealing assembly. The assembly assembly includes a sleeve, a displacement element, a locking ball, and a spring, with a pre-set opening on an external mixing tank. One end of the connecting pipe is connected to an external raw material pipeline, and the other end is connected to the sleeve. The sleeve has an annular groove, a sliding groove, and a slot. The displacement element is slidably connected to the annular groove. Both ends of the spring are fixedly connected to the displacement element and the sleeve, respectively. The displacement element has an avoidance groove. One end of the insertion pipe is placed in the slot, and the other end is inserted into a pre-set opening in the mixing tank. The insertion pipe has a locking groove, and the locking ball is slidably connected to the sliding groove and placed within the locking groove. The sealing assembly is slidably connected to the insertion pipe.

[0006] The sealing assembly includes a fixed tube and a displacement tube. The fixed tube is fixedly connected to the external mixing tank and is located at a predetermined opening. The displacement tube is slidably connected to the insertion tube and is located above the fixed tube.

[0007] The sealing assembly further includes a first sealing ring and a second sealing ring, which are respectively connected to the fixed tube and the displacement tube, and the first sealing ring is in contact with the second sealing ring.

[0008] The displacement component includes a displacement ring and a force-applying ring. The displacement ring is slidably connected to the groove and fixedly connected to the spring. The force-applying ring is fixedly connected to the end of the displacement ring away from the spring.

[0009] The sleeve has a chamfered structure, which is located at the end of the sleeve away from the insertion tube.

[0010] This utility model discloses a material feed pipe structure. In practical use, the material from an external raw material pipeline is introduced into the sleeve through the connecting pipe and then enters the mixing tank through the insertion pipe. Because an opening is pre-set on the mixing tank, the insertion pipe is suspended inside the mixing tank and does not contact it. It is sealed by the sealing component, thus not affecting the weighing accuracy of the mixing tank. When the insertion pipe needs to be disassembled, the displacement member is pushed, causing it to slide within the annular groove and contracting the spring until the avoidance groove aligns with the sliding groove. Then, the insertion pipe is pulled, causing the locking ball to enter the avoidance groove, thereby removing the insertion pipe from the slot. Conversely, this facilitates the installation of the insertion pipe. This method solves the technical problem in the prior art where the material feed pipe is directly installed on the mixing tank, thus affecting the weighing accuracy. Attached Figure Description

Detailed Implementation

[0017] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0018] Please see Figures 1-4 ,in Figure 1 This is a schematic diagram of the material feed pipe structure of this utility model. Figure 2 This is a partial structural diagram of the material feed pipe structure of this utility model. Figure 3 This is the utility model Figure 2 A cross-sectional view of the AA line structure. Figure 4 This is a schematic diagram of the structure of this utility model after assembly with a mixing tank and external raw material pipelines.

[0019] This utility model provides a material feed pipe structure, including a connecting pipe 101, an assembly assembly, an insertion pipe 102, and a sealing assembly. The assembly assembly includes a sleeve 103, a displacement component, a locking ball 104, and a spring 105. The sealing assembly includes a fixing pipe 106, a displacement pipe 107, a first sealing ring 108, and a second sealing ring 109. The displacement component includes a displacement ring 110 and a force-applying ring 111. The aforementioned solution solves the technical problem in the prior art where the material feed pipe is directly installed on the mixing tank 118, thus affecting the weighing accuracy.

[0020] In this specific embodiment, an opening is pre-set on the external mixing tank 118. One end of the connecting pipe 101 is connected to the external raw material pipe 119, and the other end of the connecting pipe 101 is connected to the sleeve 103. The sleeve 103 has an annular groove 112, a sliding groove 113, and a slot 114. The displacement member is slidably connected to the annular groove 112. The two ends of the spring 105 are fixedly connected to the displacement member and the sleeve 103, respectively. The displacement member has an avoidance groove 115. One end of the insertion pipe 102 is placed in the slot 114, and the other end of the insertion pipe 102 is inserted into the pre-set opening in the mixing tank 118. The insertion pipe 102 has a locking groove 116. The locking ball 104 is slidably connected to the sliding groove 113 and placed in the locking groove 116. The sealing assembly is slidably connected to the insertion pipe 102.

[0021] The sleeve 103 has a chamfered structure 117, which is located at the end of the sleeve 103 away from the insertion tube 102. In actual use, the raw material in the external raw material pipe 119 is introduced into the sleeve 103 through the connecting pipe 101, and then enters the mixing tank 118 through the insertion tube 102. Since there is a pre-set opening on the mixing tank 118, the insertion tube 102 is suspended in the mixing tank 118 and does not contact the mixing tank 118. It is sealed by the sealing assembly, so it will not affect the weighing accuracy of the mixing tank 118. When disassembling the insertion tube 102, the displacement member is pushed, causing it to slide within the annular groove 112 and contract the spring 105 until the avoidance groove 115 aligns with the slide groove 113. Then, the insertion tube 102 is pulled, causing the locking ball 104 to enter the avoidance groove 115, thereby removing the insertion tube 102 from the slot 114. Conversely, this facilitates the installation of the insertion tube 102. This method solves the technical problem in the prior art where the material feed pipe is directly installed on the mixing tank 118, thus affecting the weighing accuracy.

[0022] The fixed tube 106 is fixedly connected to the external mixing tank 118 and is located at the preset opening. The displacement tube 107 is slidably connected to the insertion tube 102 and is located above the fixed tube 106. The fixed tube 106 and the displacement tube 107 cooperate to seal the gap between the insertion tube 102 and the mixing tank 118.

[0023] Secondly, the first sealing ring 108 and the second sealing ring 109 are respectively connected to the fixed tube 106 and the displacement tube 107, and the first sealing ring 108 is in contact with the second sealing ring 109. The displacement tube 107 drives the second sealing ring 109 to contact the first sealing ring 108. The displacement tube 107 drives the second sealing ring 109 to be in long-term contact with the first sealing ring 108, which further improves the sealing effect.

[0024] Meanwhile, the displacement ring 110 is slidably connected to the slide groove 113, and the displacement ring 110 is fixedly connected to the spring 105. The force-applying ring 111 is fixedly connected to the end of the displacement ring 110 away from the spring 105. By applying force to the force-applying ring 111, the force-applying ring 111 drives the displacement ring 110 to move.

[0025] In the material feed pipe structure of this utility model, during specific use, the raw material in the external raw material pipe 119 is introduced into the sleeve 103 through the connecting pipe 101, and then enters the mixing tank 118 through the insertion pipe 102. Since the mixing tank 118 has a pre-set opening, the insertion pipe 102 is suspended inside the mixing tank 118 and does not contact the mixing tank 118. It is sealed by the sealing assembly, thus not affecting the weighing accuracy of the mixing tank 118. When it is necessary to disassemble the insertion pipe 102, it is done by pushing the... The displacement member slides within the annular groove 112, causing the spring 105 to contract until the avoidance groove 115 aligns with the slide groove 113. Then, the insertion tube 102 is pulled, causing the locking ball 104 to enter the avoidance groove 115, thereby removing the insertion tube 102 from the slot 114. Conversely, this facilitates the installation of the insertion tube 102. This method solves the technical problem in the prior art where the material feed pipe is directly installed on the mixing tank 118, thus affecting the weighing accuracy.

[0026] Since the displacement tube 107 is slidably connected to the insertion tube 102, the displacement tube 107 causes the second sealing ring 109 to contact the first sealing ring 108. The displacement tube 107 causes the second sealing ring 109 to be in long-term contact with the first sealing ring 108, which further improves the sealing effect.

[0027] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
