Description

Technical Field

[0001] This utility model relates to the field of material transfer technology, and in particular to a material cart. Background Technology

[0002] In current industrial production, the transportation of thermoplastic elastomer masterbatch raw materials mainly relies on material carts. These material carts are typically designed to load and transport large quantities of raw materials to meet the needs of the production line. Once the material cart arrives at the production site, workers need to push it near the discharge pipe and manually align the material cart's discharge pipe with the discharge pipe opening.

[0003] The feed pipe is a crucial component connecting to the production equipment downstairs. It protrudes from the ground to align with the discharge pipe of the material cart. However, this manual alignment method presents several inconveniences. First, the alignment process requires significant time and effort from workers, increasing their workload and potentially impacting production efficiency. Second, due to human error, inaccurate alignment can lead to material leakage or transmission disruptions, negatively affecting production.

[0004] In view of the problems of material leakage and reduced production efficiency caused by the difficulty in aligning the discharge pipe with the feed pipe and the low efficiency, a material cart is provided. Utility Model Content

[0005] The main objective of this invention is to provide a material cart to solve the problems of material leakage and reduced production efficiency caused by difficulties in aligning the discharge pipe with the feed pipe and low efficiency in related technologies.

[0006] To achieve the above objectives, according to one aspect of the present invention, a material cart is provided for transporting materials such as raw materials for the production of thermoplastic elastomer masterbatch, and is connected to a discharge pipe, which is connected to production equipment. A discharge pipe is fixedly provided at the bottom of the material cart, and a movable pipe is slidably provided on the discharge pipe. An electromagnet is embedded in the bottom of the movable pipe, and an electromagnet is embedded in the top of the discharge pipe. The movable pipe and the discharge pipe are magnetically aligned and connected, and a limiting pipe is fixedly provided on the outside of the discharge pipe to prevent the movable pipe from deviating.

[0007] Furthermore, a chute is provided inside the discharge pipe, and a spring is fixedly installed inside the chute, with one end of the spring fixedly connected to the inner wall of the chute.

[0008] Furthermore, the other end of the spring is fixedly connected to the movable tube, which is slidably installed in the groove.

[0009] Furthermore, an elastic block is fixedly provided on the inner side of the bottom of the limiting tube. The elastic block is annular, and the upper surface of the elastic block is fixedly connected to the lower surface of the discharge tube.

[0010] Furthermore, a connecting block is fixedly installed at the bottom of the discharge pipe. The connecting block is annular, and its outer wall is provided with dense bristles. The connecting block is used to clean the raw materials remaining on the surface of the moving pipe.

[0011] Furthermore, when the movable tube extends and retracts downwards magnetically to connect with the feeding tube, the side wall of the elastic block is tightly fitted with the outer wall of the movable tube, and the side wall of the connecting block is tightly fitted with the inner wall of the movable tube.

[0012] Furthermore, a groove is provided at the top of the feeding tube, and the bottom of the movable tube is magnetically attached to the groove, with the bottom surface of the movable tube closely fitting the side wall of the groove.

[0013] Furthermore, the inner side of the groove is chamfered, and the width of the groove is equal to the width of the movable tube.

[0014] Furthermore, a guide plate is fixedly provided on the feeding pipe. The guide plate is annular, and its diameter gradually decreases from top to bottom.

[0015] Furthermore, the lower diameter of the guide plate is equal to the diameter of the feed tube, and the upper diameter of the guide plate is greater than the diameter of the limiting tube.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In this material cart, an electromagnet is embedded at the connection between the movable tube and the discharge tube, which realizes the automatic magnetic attraction docking of the movable tube and the discharge tube. The spring provides a stable restoring force for the movable tube. After the electromagnet is de-energized, the spring can quickly play its role and pull the movable tube back to the initial position, ensuring the smooth progress of the next docking.

[0018] 2. In this material cart, a limiting tube is set up to prevent the movable tube from shifting during the reset process and to avoid interfering with the normal sliding of the movable tube. The design of the elastic block further enhances the functionality of the limiting tube. It avoids direct contact between the limiting tube and the movable tube, reducing the possibility of wear and damage. The brush design on the outer wall of the connecting block cleverly solves the problem of residual raw materials on the inner wall of the movable tube, preventing these raw materials from entering the chute and causing blockage or contamination.

[0031] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0032] Please see Figures 1-9 As shown, the purpose of this embodiment is to provide a material cart for transporting materials such as raw materials for producing thermoplastic elastomer masterbatch, and it can be connected to the feeding pipe 3, which is connected to the production equipment.

[0033] The material cart 1 is fixedly provided with a discharge pipe 2 at the bottom, and a movable pipe 23 is slidably provided on the discharge pipe 2. An electromagnet is embedded in the bottom of the movable pipe 23 and an electromagnet is embedded in the top of the discharge pipe 3. The movable pipe 23 and the discharge pipe 3 are magnetically aligned and connected. A limiting pipe 4 is fixedly provided on the outside of the discharge pipe 2 to prevent the movable pipe 23 from deviating.

[0034] A chute 21 is provided inside the discharge pipe 2, and a spring 22 is fixedly installed inside the chute 21. One end of the spring 22 is fixedly connected to the inner wall of the chute 21.

[0035] The other end of spring 22 is fixedly connected to movable tube 23, which is slidably installed in chute 21. When material needs to be discharged from material cart 1, the electromagnet at the bottom of movable tube 23 is energized and attracted to the electromagnet at the top of discharge tube 3, causing movable tube 23 to overcome the elastic force of spring 22 under the action of electromagnetic force and slide downward to the position where it connects with discharge tube 3. After the material is discharged, the electromagnet is de-energized, and the elastic force of spring 22 quickly takes effect, pulling movable tube 23 back to its initial position, i.e., the top of chute 21. Figure 2 , Figure 3 , Figure 6 The figure shows the position and state of the movable tube 23 and the spring 22 in the initial state.

[0036] An elastic block 41 is fixedly installed on the inner side of the bottom of the limiting tube 4. The elastic block 41 is annular, and the upper surface of the elastic block 41 is fixedly connected to the lower surface of the discharge tube 2. The setting of the limiting tube 4 can prevent the movable tube 23 from shifting during the reset process, and will not interfere with the normal sliding of the movable tube 23. The design of the elastic block 41 avoids contact between the limiting tube 4 and the movable tube 23. During the sliding or reset process of the movable tube 23, even if a slight shift occurs, the elastic block 41 can buffer and adjust it with its softness, thereby effectively reducing the wear and damage to the movable tube 23.

[0037] A connecting block 5 is also fixedly installed at the bottom of the discharge pipe 2. The connecting block 5 is annular and its outer wall is covered with dense bristles. During the feeding process, the inner wall of the movable pipe 23 will come into contact with the raw material for producing thermoplastic elastomer masterbatch, and some raw material particles may remain on the surface. When the movable pipe 23 is reset under the force of the spring 22, it will slide upward along the slide 21 and pass through the connecting block 5. The bristles on the outer wall of the connecting block 5 can remove the residual raw material on the inner wall of the movable pipe 23, preventing these raw materials from entering the slide 21.

[0038] When the movable tube 23 magnetically extends downwards and connects with the feeding tube 3, the side wall of the elastic block 41 is tightly attached to the outer wall of the movable tube 23, the side wall of the connecting block 5 is tightly attached to the inner wall of the movable tube 23, and the bristles are tightly attached to the inner wall of the movable tube 23 to effectively remove residual raw materials from the inner wall.

[0039] A groove 31 is provided at the top of the feeding pipe 3. When the material cart 1 needs to feed material into the production equipment, the electromagnet at the bottom of the movable pipe 23 attracts the magnetic part of the electromagnet at the bottom of the groove 31. The bottom of the movable pipe 23 is magnetically attached to the groove 31, and the bottom surface of the movable pipe 23 is tightly fitted to the side wall of the groove 31. Due to the magnetic attraction, the connection between the movable pipe 23 and the feeding pipe 3 is very strong. Even if a certain impact force is generated during material transmission, the stability and reliability of the connection can be maintained. Figure 3 , Figure 4 The diagram shows the magnetic connection between the moving tube 23 and the feeding tube 3.

[0040] The inner side of the groove 31 is chamfered, and the width of the groove 31 is equal to the width of the movable tube 23. When the movable tube 23 and the groove 31 are connected, due to the chamfer design, a smooth transition area is formed at the connection, and the raw material will not accumulate or stagnate at the connection, reducing the possibility of the raw material entering the connection.

[0041] A guide plate 6 is fixedly installed on the feed pipe 3. The guide plate 6 is annular and its diameter gradually decreases from top to bottom.

[0042] The lower diameter of the guide plate 6 is equal to the diameter of the feed tube 3, and the upper diameter of the guide plate 6 is greater than the diameter of the limiting tube 4. When the movable tube 23 moves downward under the action of electromagnetic force, preparing to magnetically connect with the groove 31 of the feed tube 3, the guide plate 6 plays a key guiding role, enabling the movable tube 23 to gradually approach the groove 31 of the feed tube 3 along this channel. This not only ensures that the movable tube 23 can accurately dock with the groove 31, but also reduces the problem of unstable connection caused by offset or shaking.

[0043] In practical use, when the material cart 1 needs to unload materials into the production equipment, the electromagnets at the bottom of the movable tube 23 and the top of the unloading tube 3 are activated, causing them to be energized and attracted. Under the action of electromagnetic force, the movable tube 23 overcomes the elastic force of the spring 22 and slides down along the slide groove 21 to the position where it docks with the unloading tube 3. At this time, the guide plate 6 ensures that the movable tube 23 can accurately dock with the groove 31 of the unloading tube 3. After the movable tube 23 docks with the unloading tube 3, the material in the material cart 1 is transferred to the production equipment through the discharge tube 2, the movable tube 23 and the unloading tube 3. After the material is unloaded, the power supply of the electromagnets at the bottom of the movable tube 23 and the top of the unloading tube 3 is disconnected, causing them to be de-energized and separated. Under the action of the elastic force of the spring 22, the movable tube 23 slides up along the slide groove 21 to the initial position, and the bristles on the outer wall of the connecting block 5 will remove the residual raw materials on the inner wall of the movable tube 23, preventing these raw materials from entering the slide groove 21.

[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
