Description

Technical Field

[0001] The utility model relates to the technical field of nut production, in particular to a loading and unloading device for straight-through nut production. Background Art

[0002] The straight-through nut shot blasting machine is an efficient and precise metal surface treatment equipment, which is specially used for shot blasting and cleaning of fasteners such as straight-through nuts. The machine uses a high-speed rotating shot blasting wheel to forcefully project shot blasting materials onto the surface of the nut, effectively removing surface dirt, scale, rust and other impurities, while increasing the surface roughness of the nut, improving its coating adhesion and anti-corrosion performance. The straight-through nut shot blasting machine has the advantages of compact structure, easy operation, high processing efficiency and good cleaning effect. It is widely used in machinery manufacturing, automobiles, aerospace and other fields, providing a strong guarantee for improving product quality and extending service life.

[0003] In the current straight-through nut processing process, using a tipping hopper for loading is a key link. However, since a large amount of rust and dust often adheres to the surface of the nuts before shot blasting, these dirt can easily generate a large amount of dust and rust flying in the process of the nuts being dumped into the tipping hopper. This situation not only pollutes the working environment, but more seriously, it directly threatens the health of on-site operators, exposing them to this harmful substance for a long time, increasing the risk of respiratory diseases and other health problems. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a loading and unloading device for the production of straight-through nuts, so as to solve the technical problem of rust residue and dust flying during the nut tipping process.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a loading and unloading device for the production of straight-through nuts, comprising a support frame and a tipping hopper main body, a movable door is provided on one side of the tipping hopper main body, and a dust shield plate is rotatably connected to the top side of the movable door through a damping shaft, and limiting rods are provided on both sides of the inner wall of the tipping hopper main body, the limiting rods are in contact with the dust shield plate, and the dust shield plate is an inclined structure.

[0006] By adopting the above technical solution, the dust shield effectively limits the smoke and dust generated by the falling of the nut material and the friction and collision between the materials to the inside due to the blocking of the internal nut material by the dust shield. This design directly prevents the smoke and dust from spreading to the external environment, thereby significantly improving the protectiveness of the working environment.

[0007] Furthermore, the dust shield is of a rectangular structure, and the dust shield is opposite to the upper opening of the tipping hopper body.

[0008] By adopting the above technical solution, the rectangular structure of the dust shield enables it to effectively cover the upper opening of the tipping hopper body. This structural correspondence ensures that when the nut material is dumped, the smoke and dust are mainly confined inside the tipping hopper, reducing the escape of smoke and dust to the external environment.

[0009] Furthermore, the movable door is connected to the tipping hopper body in a detachable structure, and the limit rod is fixed to the inner wall of the tipping hopper body by welding.

[0010] By adopting the above technical solution, the movable door and the dust shield can be easily installed, disassembled and maintained, which not only improves the maintainability of the equipment, but also facilitates cleaning and replacement of parts, thereby extending the service life of the equipment.

[0011] Furthermore, adjustment mechanisms are provided on both sides of the tipping hopper body, and the adjustment mechanisms are used to limit the rotation angle of the dust shield.

[0012] By adopting the above technical solution, the adjustment mechanisms arranged on both sides of the tipping hopper body can limit the rotation angle of the dust shield, ensuring that the dust shield always maintains an effective limiting effect during the material dumping and processing process, preventing smoke and dust from spreading to the external environment.

[0013] Furthermore, the adjustment mechanism includes a mounting groove, a clamping groove is provided on one side of the mounting groove, a mounting screw is provided inside the mounting groove, and the mounting groove is a straight groove structure.

[0014] By adopting the above technical solution, the mounting screw rod can be stably moved and adjusted therein, thereby ensuring the accurate positioning and stability of the mounting screw rod, thereby effectively limiting the rotation angle of the dust shield.

[0015] Furthermore, a clamping block is arranged at one end of the mounting screw rod, the clamping groove is engaged with the clamping block, and the clamping block is a hexagonal structure.

[0016] By adopting the above technical solution, the stability and accurate positioning of the mounting screw in the mounting slot are ensured, and the hexagonal structure makes it difficult for the card block to slide or rotate in the card slot, thereby enhancing the overall stability.

[0017] Furthermore, the mounting screw is mounted and fixed to the tipping hopper body by means of a fastening nut.

[0018] By adopting the above technical solution, the connection between the adjusting mechanism and the tipping hopper body is ensured to be firm and reliable. This fixing method can withstand the vibration and force during the working process and maintain the stability and accuracy of the adjusting mechanism.

[0019] Furthermore, a pressure rod is fixedly connected to the other side of the clamping block, and the cross-sections of the pressure rod and the limiting rod are both circular structures.

[0020] By adopting the above technical solution, the pressure rod can interact with the limiting rod when the dust shield is working, effectively limiting the rotation angle of the dust shield, ensuring that the dust shield moves within a predetermined range and preventing it from over-rotating or deviating from the correct position.

[0021] Furthermore, the outer sides of the pressing rod and the limiting rod are both sleeved with protective sleeves, and the material of the protective sleeves is rubber.

[0022] By adopting the above technical solution, the pressure rod and the limit rod can be protected from corrosion, wear and impact in the external environment, thereby extending the service life of the equipment.

[0023] Furthermore, the support frame is rotatably connected to the tipping hopper body, and two hydraulic push rods are arranged between the support frame and the tipping hopper body.

[0024] By adopting the above technical solution, the tipping hopper body can be flexibly rotated during the dumping and loading processes, thereby improving the operability and ease of use of the equipment.

[0025] In summary, the utility model mainly has the following beneficial effects:

[0026] 1. The utility model uses a dust shield. Due to the dust shield's blocking effect on the internal nut material, it effectively limits the smoke and dust generated by the falling of the nut material and the friction and collision between the materials to the inside. This design reduces the diffusion of smoke and dust to the external working environment, thereby significantly improving the cleanliness and protection of the working environment. At the same time, by blocking the diffusion of smoke and dust, the dust shield also reduces the risk of workers being exposed to harmful smoke and dust, effectively protecting their health, which is not only reflected in improving the working environment, but also in the long-term protection of the health of the workers;

[0027] 2. The utility model sets an adjustment mechanism. As the hopper body turns over, the dust shield rotates naturally through the damping shaft until it contacts the pressure rod. This design ensures that the dust shield will not hinder the opening of the hopper body during the dumping process, thereby ensuring that the nut material can smoothly enter the hopper. The rotation of the dust shield also increases the opening size of the hopper body, further facilitating the loading operation of the nut material. At the same time, since the installation groove is designed as a straight groove structure, the installation screw can be installed in different positions as needed, so that the pressure point of the dust shield can be adjusted according to actual needs, thereby better adapting to different installation environments and improving the applicability of the equipment.

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0035] The following describes an embodiment of the utility model based on its overall structure.

[0036] Embodiment 1:

[0037] A loading and unloading device for straight nut production, such as Figure 1-Figure 5 As shown, it includes a support frame 1 and a tipping hopper body 2, a movable door 4 is arranged on one side of the tipping hopper body 2, a dust shield plate 5 is rotatably connected to the top side of the movable door 4 through a damping shaft 8, and limiting rods 6 are arranged on both sides of the inner wall of the tipping hopper body 2, the limiting rods 6 are abutted against the dust shield plate 5, and the dust shield plate 5 is an inclined structure. Since the dust shield plate 5 blocks the internal nut material, it effectively limits the smoke and dust generated by the falling of the nut material and the friction and collision between the materials on its inner side. This design directly prevents the smoke and dust from diffusing to the external environment, thereby significantly improving the protectiveness of the working environment. At the same time, by blocking the smoke and dust, the dust shield plate 5 also plays a role in protecting the health of the staff. Since the chance of the staff being exposed to harmful smoke and dust is reduced, the risk of them suffering from smoke-related diseases is reduced, thereby improving the health protection of the overall workplace.

[0038] See also Figure 1 , Figure 3The dust shield plate 5 is of a rectangular structure, and the dust shield plate 5 is opposite to the upper opening of the tipping hopper main body 2. The rectangular structure of the dust shield plate 5 enables it to effectively cover the upper opening of the tipping hopper main body 2. This structural correspondence ensures that when the nut material is dumped, the smoke and dust are mainly confined inside the tipping hopper, reducing the escape of smoke and dust to the external environment. At the same time, since the dust shield plate 5 is opposite to the upper opening of the tipping hopper main body 2, it can continuously and effectively block the diffusion of smoke and dust during the entire process of the nut material being dumped and processed, thereby maintaining the cleanliness of the working environment and reducing the impact on the external environment and the health of the staff.

[0039] See also Figure 1 , Figure 3 The movable door 4 is connected to the tipping hopper body 2 in a detachable structure, and the limit rod 6 is welded and fixed to the inner wall of the tipping hopper body 2, so that the movable door 4 and the dust shield 5 can be easily installed, disassembled and maintained, which not only improves the maintainability of the equipment, but also facilitates cleaning and replacement of parts, thereby extending the service life of the equipment. At the same time, welding fixation is adopted to ensure the stability and reliability of the limit rod 6, which can withstand greater force and vibration, and effectively prevent the limit rod 6 from loosening or falling off, thereby ensuring the normal operation and safety of the equipment.

[0040] Embodiment 2:

[0041] See also Figure 3 , Figure 4 , Figure 5 , adjustment mechanisms 7 are provided on both sides of the tipping hopper body 2, and the adjustment mechanisms 7 are used to limit the rotation angle of the dust shield plate 5. The adjustment mechanisms 7 provided on both sides of the tipping hopper body 2 can limit the rotation angle of the dust shield plate 5, ensuring that the dust shield plate 5 always maintains an effective limiting effect during the material dumping and processing process to prevent smoke and dust from diffusing to the external environment. At the same time, the adjustment mechanism 7 also allows the user to adjust the inclination angle of the dust shield plate 5 and the opening size of the tipping hopper body 2 according to actual needs, so as to optimize and adapt to different working scenes. This flexibility improves the applicability and work efficiency of the equipment.

[0042] See also Figure 3 , Figure 4 , Figure 5The adjusting mechanism 7 includes a mounting groove 701, a card slot 702 is provided on one side of the mounting groove 701, and a mounting screw 703 is provided inside the mounting groove 701. The mounting groove 701 is a straight groove structure, so that the mounting screw 703 can stably move and adjust its position therein, ensuring the accurate positioning and stability of the mounting screw 703, thereby effectively limiting the rotation angle of the dust guard plate 5. At the same time, the card slot 702 provided on one side of the mounting groove 701 cooperates with the card block 704 on the mounting screw 703, further enhancing the stability of the mounting screw 703 in the mounting groove 701, preventing it from accidentally loosening or falling off during use, and improving the safety and reliability of the equipment.

[0043] See also Figure 3 , Figure 4 , Figure 5 A block 704 is set at one end of the mounting screw 703, and the slot 702 is engaged with the block 704. The block 704 has a hexagonal structure, which ensures the stability and accurate positioning of the mounting screw 703 in the mounting slot 701. The hexagonal structure makes it difficult for the block 704 to slide or rotate in the slot 702, thereby enhancing the overall stability. At the same time, the design of the hexagonal block 704 also facilitates the installation and disassembly process. The staff can more easily identify and operate the block 704, thereby improving the maintainability and ease of use of the equipment.

[0044] See also Figure 3 , Figure 4 , Figure 5 The mounting screw 703 is fixed to the tipping hopper body 2 by means of the fastening nut 706, ensuring a firm and reliable connection between the adjusting mechanism 7 and the tipping hopper body 2. This fixing method can withstand the vibration and force during operation and maintain the stability and accuracy of the adjusting mechanism 7. At the same time, the use of the fastening nut 706 for installation and fixation also facilitates the assembly and maintenance of the equipment. The staff can easily tighten or loosen the nut to complete the fixation or adjustment of the mounting screw 703, thereby improving the ease of use and maintainability of the equipment.

[0045] See also Figure 3 , Figure 4 , Figure 5 The other side of the block 704 is fixedly connected with a pressure rod 705. The cross-sections of the pressure rod 705 and the limiting rod 6 are both circular structures. The pressure rod 705 can interact with the limiting rod 6 when the dust shield plate 5 is working, effectively limiting the rotation angle of the dust shield plate 5, ensuring that the dust shield plate 5 moves within a predetermined range and preventing it from excessive rotation or deviation from the correct position. At the same time, the cross-sections are both circular structures, and the two can roll or slide more smoothly when in contact, reducing friction and wear and extending the service life of the equipment.

[0046] See also Figure 3 , Figure 4 , Figure 5 The outer sides of the pressure rod 705 and the limiting rod 6 are both sleeved with a protective sleeve 707, which is made of rubber and can protect the pressure rod 705 and the limiting rod 6 from corrosion, wear and impact in the external environment, thereby extending the service life of the equipment. At the same time, the rubber protective sleeve 707 also has a certain buffering effect, which can absorb and disperse the impact force generated by the interaction between the pressure rod 705, the limiting rod 6 and the dust shield 5, thereby reducing the noise and vibration of the equipment during operation and improving the comfort of use of the equipment.

[0047] See also Figure 1 , Figure 2 The support frame 1 is rotatably connected to the tipping hopper body 2, and two hydraulic push rods 3 are arranged between the support frame 1 and the tipping hopper body 2, so that the tipping hopper body 2 can be flexibly rotated during the dumping and loading process, which improves the operability and ease of use of the equipment. At the same time, the two hydraulic push rods 3 arranged between the support frame 1 and the tipping hopper body 2 provide a stable and powerful thrust, ensuring the smooth movement of the tipping hopper body 2 during the dumping and loading process, which not only improves the working efficiency of the equipment, but also reduces the labor intensity of the staff.

[0048] The implementation principle of the utility model is as follows: first, a part of the straight-through nuts are dumped into the interior of the tipping hopper body 2 by using a traveling crane. At this time, the falling nut materials slide into the interior of the tipping hopper body 2 through the inclined dust shield 5. Since the dust shield 5 blocks the internal nut materials, it is beneficial to block the smoke and dust generated by the falling nut materials and the friction and collision between the materials on the inner side of the dust shield 5, which is beneficial to improve the protection of the external working environment and the health protection of the staff. When the dumping is completed, the hydraulic push rod 3 is used to push the tipping hopper body 2, causing the tipping hopper body 2 to rotate until the internal nut materials are The hopper body 2 slides down through the tilting inclined surface into the interior of the shot blasting machine. During this process, as the hopper body 2 gradually turns over, due to gravity, the dust shield 5 rotates through the damping shaft 8 until the dust shield 5 abuts against the pressing rod 705 and increases the opening size of the hopper body 2, which is beneficial to prevent the dust shield 5 from hindering the feeding operation of the nut material. After the feeding is completed, the hydraulic push rod 3 contracts to cause the hopper body 2 to return to its initial position. At the same time, the dust shield 5 rotates through the damping shaft 8 and is limited by the limit rod 6 to place the dust shield 5 at an initial tilt.

[0049] First, make the installation screw 703 pass through the installation slot 701, and at the same time make the block 704 engage with the slot 702, and use the fastening nut 706 to complete the installation of the installation screw 703. According to the size of the opening required for the dust shield plate 5, the installation screw 703 can be installed in different positions through the installation slot 701 with a straight groove structure, which is conducive to adjusting the pressure point of the dust shield plate 5 and improving the applicability of the installation environment.

[0050] Parts not involved in the present invention are the same as the prior art or can be implemented by using the prior art, and will not be described in detail here.

[0051] Although an embodiment of the utility model has been shown and described, this specific embodiment is only an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the utility model.
