Description
Technical Field
[0001] This utility model belongs to the field of tooling vehicle technology, and in particular relates to a dustproof bag tooling vehicle. Background Technology
[0002] In the production and processing process, tooling carts are a commonly used material handling and storage equipment. After the products are processed, they usually need to be stored on tooling carts and transported to the next process or warehouse. However, the production environment often contains a lot of dust, debris and other impurities. These impurities are easy to adhere to the product surface, which not only affects the appearance quality of the product, but may also have an adverse effect on its performance. Dustproof bag tooling carts are tooling carts with dustproof cloths installed on the outside of the tooling carts to protect the products inside the tooling carts.
[0003] Although the bag-type work cart is covered with dustproof cloth, in actual operation, the dustproof cloth is fixed in a simple way and is easily moved or fallen off by external factors, which cannot provide continuous and stable protection. In addition, the existing work cart protective structure lacks a roll-up design, and occupies a lot of space when idle, which is not conducive to warehouse management and logistics transportation.
[0004] To address these issues, we provide a dustproof bag handling vehicle. Utility Model Content
[0005] The purpose of this utility model is to provide a dustproof bag trolley, which solves the problems of existing trolleys lacking a winding design, occupying a large space when idle, and being unfavorable for warehouse management and logistics transportation by cooperating with the storage mechanism and positioning mechanism.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.
[0007] This utility model relates to a dustproof bag handling vehicle, comprising a base frame, with support columns fixedly connected to the four corners of the top of the base frame. Storage mechanisms are fixedly connected to the top and bottom of opposite sides of the support columns. Positioning mechanisms are fixedly connected to both sides of the storage mechanism. The storage mechanism includes a housing, with a protective bag fixedly connected to the inner cavity of the housing. A groove is formed on one side of the top of the housing, and a rotating roller is movably connected to one side of the inner cavity of the groove via a bearing. A protective curtain is provided on the surface of the rotating roller, and a worm gear is fixedly connected to the front end of the rotating roller. A motor is fixedly connected to one side of the housing, and a worm is fixedly connected to the output end of the motor. One side of the worm penetrates one side of the housing and extends into the inner cavity of the groove. The worm meshes with the worm wheel. The protective bags are made of dustproof and waterproof fabric and have internal dividers to classify and store work bags of different sizes and types. The roller surface is treated with an anti-slip coating, and a protective curtain made of transparent PVC material is tightly wrapped around the roller surface. The curtain is flexible and has a significant dustproof effect. The worm gear and worm wheel mesh with each other, and the precise gear transmission ratio design ensures the smooth opening and closing of the protective curtain. The dustproof and waterproof fabric and divider design of the work bag effectively isolate dust and moisture, preventing the work bags from being contaminated and damaged. At the same time, it facilitates classification management and improves storage and retrieval efficiency. The motor drives the worm gear and worm wheel to move the protective curtain up and down. The protective curtain can be quickly opened when storing or retrieving work bags and closed promptly after operation to reduce dust entry and further enhance the dustproof effect.
[0008] The present invention is further configured such that the positioning mechanism includes a support plate, both ends of which are fixedly connected to support columns, a positioning seat is fixedly connected to one side of the support plate, a limiting groove is formed on the top of the positioning seat, mounting seats are fixedly connected to both sides of the outer shell, and a limiting block that cooperates with the limiting groove is fixedly connected to the bottom of the mounting seat. When installing the storage mechanism, the positioning can be quickly completed by simply aligning the limiting block with the limiting groove and inserting it, without the need for a complicated calibration process, which greatly improves the installation efficiency. At the same time, it limits the horizontal displacement of the storage mechanism, ensuring that it remains stable during the movement of the tooling vehicle and preventing damage or falling of the internal tooling bag due to shaking.
[0009] The present invention is further configured such that a push rod is fixedly connected to one side of the support column, and a protective sleeve is fixedly connected to the surface of the push rod. The push rod provides the operator with a convenient point of force application, making it easy to push the tooling cart to move in the workshop. Especially when moving heavy tooling bags, the push rod can make the operation more labor-saving.
[0010] The present invention is further configured such that each of the four corners of the bottom of the base frame is fixedly connected to a bracket, and the bottom of the bracket is movably connected to a roller via a pivot. The roller can rotate freely and can flexibly change the direction of movement to adapt to narrow or complex workshop passage environments.
[0011] The present invention is further configured such that hooks are fixedly connected to the front and rear ends of one side of the protective curtain, and a slot for cooperating with the hooks is opened on one side of the top of the outer shell. When the protective curtain is unfolded to cover the protective bag of the work clothes, the hooks can be hooked into the slots to firmly fix the protective curtain, preventing the protective curtain from shaking or shifting due to factors such as airflow in the workshop or movement of the work clothes vehicle, thus ensuring the dustproof effect.
[0012] The present invention is further configured such that a long groove is provided on one side of the inner cavity of the outer shell, and one side of the protective curtain extends to the top of the tooling protective bag through the long groove. The long groove allows the protective curtain to extend to the top of the tooling protective bag, ensuring that the protective curtain completely covers the tooling protective bag without any dust-proof dead corners.
[0013] The present invention is further provided with fasteners on both sides of the surface of the mounting base, and one side of the mounting base is fixedly connected to the outer shell by the fasteners. The mounting base is installed to the outer shell by the fasteners, which ensures the stability of the mounting base installation.
[0014] The present invention has the following beneficial effects.
[0015] 1. This utility model forms a double-layer protection system through the tooling protective bag and the protective curtain inside the outer shell. The tooling protective bag completely wraps the metal products and isolates them from external pollutants, while the protective curtain protects the top of the tooling vehicle. This comprehensively prevents dust, debris, and other contaminants from entering the tooling vehicle, effectively protecting the surface of the metal products from contamination and ensuring product quality.
[0016] 2. This utility model achieves easy raising and lowering of the protective curtain through a worm gear transmission structure. The operator only needs to rotate the worm, which meshes with the worm wheel to drive the rotating roller to complete the raising or lowering of the protective curtain. Compared with the manual handling of traditional dustproof cloth, this design is simpler and faster to operate, greatly improving work efficiency. Moreover, after the protective curtain is raised, it can reduce the space occupied by the tooling cart, making it convenient for storage and transportation. Attached Figure Description

Storage mechanisms 3 are fixedly connected to the top and bottom of the opposite side of the support columns 2. Positioning mechanisms 4 are fixedly connected to both sides of the storage mechanism 3. The storage mechanism 3 includes a shell 31. A tooling protective bag 32 is fixedly connected to the inner cavity of the shell 31. A groove 33 is opened on one side of the top of the shell 31. A rotating roller 34 is movably connected to one side of the inner cavity of the groove 33 through a bearing. A protective curtain 35 is provided on the surface of the rotating roller 34. A worm gear 36 is fixedly connected to the front end of the rotating roller 34. A motor 37 is fixedly connected to one side of the shell 31. A worm 38 is fixedly connected to the output end of the motor 37. One side of the worm 38 penetrates one side of the shell 31 and extends into the inner cavity of the groove 33. The worm 38 meshes with the worm gear 36.
[0027] Specifically: The protective bag 32 is made of dustproof and waterproof fabric and has an internal divider layer, which can classify and store work bags of different sizes and types. The surface of the roller 34 is treated with anti-slip material, and the protective curtain 35, made of transparent PVC material, is tightly wrapped around the surface of the roller 34. It is flexible and has a significant dustproof effect. The worm gear 38 and the worm wheel 36 mesh, and through the precise gear transmission ratio design, the protective curtain 35 can be opened and closed smoothly. The dustproof and waterproof fabric and divider layer design of the protective bag 32 can effectively isolate dust and moisture, prevent the work bags from being contaminated and damaged, and facilitate classification management and improve storage and retrieval efficiency. The motor 37 drives the worm gear 38 and the worm wheel 36 to move the protective curtain 35. The protective curtain 35 can be opened quickly when storing or retrieving work bags and closed in time after the operation to reduce dust entry and further enhance the dustproof effect.
[0028] Example 2
[0029] Please see Figure 1-5 Based on Embodiment 1, the positioning mechanism 4 includes a support plate 41, both ends of which are fixedly connected to the support column 2. A positioning seat 42 is fixedly connected to one side of the support plate 41. A limiting groove 43 is opened on the top of the positioning seat 42. Mounting seats 44 are fixedly connected to both sides of the outer shell 31. A limiting block 45 that cooperates with the limiting groove 43 is fixedly connected to the bottom of the mounting seat 44. A push rod 5 is fixedly connected to one side of the support column 2. A protective sleeve is fixedly connected to the surface of the push rod 5. A bracket 6 is fixedly connected to the four corners of the bottom of the base frame 1. A roller is movably connected to the bottom of the bracket 6 through a rotating shaft. A hook 7 is fixedly connected to the front and rear ends of one side of the protective curtain 35. A slot 8 that cooperates with the hook 7 is opened on one side of the top of the outer shell 31. A long groove 9 is opened on one side of the inner cavity of the outer shell 31. One side of the protective curtain 35 extends to the top of the tooling protective bag 32 through the long groove 9. Fasteners 10 are provided on both sides of the surface of the mounting seat 44. One side of the mounting seat 44 is fixedly connected to the outer shell 31 through the fastener 10.
[0030] Specifically: When installing the storage mechanism 3, simply align the limiting block 45 with the limiting slot 43 and insert it to quickly complete the positioning without a complicated calibration process, greatly improving installation efficiency. Simultaneously, it restricts the horizontal displacement of the storage mechanism 3, ensuring its stability during the movement of the tooling cart and preventing damage or falling of the internal tooling bags due to shaking.

Especially when handling heavy tooling bags, the push rod 5 makes operation more effortless. The rollers can rotate freely, allowing for flexible adjustment of movement. The direction of movement adapts to narrow or complex workshop passage environments. When the protective curtain 35 is unfolded to cover the tooling protective bag 32, the hook 7 can be hooked into the slot 8 to firmly fix the protective curtain 35, preventing the protective curtain 35 from shaking or shifting due to factors such as airflow in the workshop or movement of the tooling cart, thus ensuring the dustproof effect. The long slot 9 allows the protective curtain 35 to extend above the tooling protective bag 32 through the long slot 9, ensuring that the protective curtain 35 completely covers the tooling protective bag 32 without any dustproof dead corners. The mounting base 44 is installed with the outer shell 31 through the fastener 10, ensuring the stability of the mounting base 44 during installation.
[0031] The working principle of this utility model is as follows: When installing the storage mechanism 3, the limiting block 45 is inserted into the limiting groove 43 at the top of the positioning seat 42. Through the cooperation of the limiting block 45 and the limiting groove 43, the positioning of the storage mechanism 3 is quickly completed, which restricts the horizontal displacement of the storage mechanism 3 and ensures that the storage mechanism 3 remains stable during the movement of the tooling vehicle, thus preventing the internal tooling bag from being damaged or falling off due to shaking.
[0032] During the storage and retrieval process, the motor 37 drives the worm gear 38 to rotate, and the worm gear 38 meshes with the worm wheel 36 to drive the roller 34 to rotate synchronously. As the roller 34 rotates, the protective curtain 35 is retracted and extended in the groove 33, exposing the tooling protective bag 32. After the operation is completed, the motor 37 drives the roller 34 in the reverse direction to unfold the protective curtain 35 to cover the tooling protective bag 32. At the same time, the hook 7 is hooked into the slot 8 on the top side of the outer shell 31 to firmly fix the protective curtain 35, preventing it from shaking or shifting due to factors such as airflow in the workshop or movement of the tooling cart, thus ensuring the dustproof effect. The tooling protective bag 32 is made of dustproof and waterproof fabric, and the internal divider layer can classify and store tooling bags of different sizes and types, effectively isolating dust and moisture, preventing the tooling bags from being contaminated and damaged, facilitating classification management, and improving storage and retrieval efficiency.
