[0001] The utility model relates to the technical field of sandblasting mechanical equipment, in particular to a sandblasting machine door. Background Art

[0002] Current sandblasting machines generally include two functions: automatic sandblasting and manual sandblasting. However, in order to realize automatic sandblasting at the same time, the workbench in the prior art is generally set in the middle of the sandblasting machine, and both manual sandblasting and automatic sandblasting share the same workbench. Some sandblasting machines are equipped with a movable conveyor line to transport the workpiece on the workbench out when the automatic sandblasting operation is completed.

[0003] This design in the prior art requires the use of a sandblasting machine for manual sandblasting. Since the workbench is far away from the manual operation port, it is more difficult for the operator to control the spray gun, which may cause uneven distribution of the sandblasting medium, thereby affecting the quality of the workpiece surface treatment. At the same time, the longer distance may make it difficult for the operator to clearly see the details of the workpiece, especially in the presence of dust or insufficient lighting, which will affect the operator's ability to judge whether the sandblasting has achieved the desired effect. Precise control of the sandblasting angle and distance is essential to obtain a uniform and consistent surface treatment effect. The sandblasting machine of this structure in the prior art seriously affects the sandblasting efficiency of the workpiece and the yield rate of the workpiece.

[0004] Therefore, how to overcome the above-mentioned defects has become an important issue to be solved urgently by those skilled in the art. Utility Model Content

[0005] The utility model overcomes the shortcomings of the above-mentioned technology and provides a sandblasting machine door.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A sandblasting machine door comprises a door body, an observation window and an operating port installed below the observation window are installed on the door body, two operating ports are symmetrically arranged, an automatic wiper attached to the inner wall of the observation window is connected to the inner side of the door body, and a foldable workbench is also installed on the inner side of the door body. When the workbench is fully unfolded, its table top is perpendicular to the door body and faces the operating port, so that personnel can process the workpiece on the workbench through the operating port.

[0021] The following examples further illustrate the features of the present invention and other related features to facilitate understanding by those skilled in the art:

[0022] like Figures 1 to 3 As shown, the present case discloses a sandblasting machine door, including a door body 100, on which an observation window 1 and an operating port 2 installed below the observation window 1 are installed. In a specific implementation, the observation window 1 is installed at the upper end of the door body 100, so that different operators can observe the sandblasting situation in the door body through the observation window 1, thereby ensuring the sandblasting efficiency and yield rate of the workpiece. There are two operating ports 2 symmetrically arranged. In a specific implementation, each operating port 2 is connected with a glove, and in order to effectively protect the operator's hands, the glove can be a rubber glove with good wear resistance and corrosion resistance. An automatic wiper 3 that fits the inner wall of the observation window 1 is connected to the inner side of the door body 100.

[0023] When performing manual sandblasting, the operator puts both hands into the operating port 2 and sandblasts the designated workpiece under the protection of rubber gloves. During the sandblasting process, the sandblasting on the inside of the observation window 1 is scraped off by the automatic wiper 3, which can ensure the cleaning of the line of sight and improve the quality of sandblasting. A foldable workbench 4 is also installed on the inside of the door body 100. When the workbench 4 is fully unfolded, its tabletop is perpendicular to the door body 100 and faces the operating port 2, so that the personnel can process the workpiece on the workbench 4 through the operating port 2. When the workbench 4 is fully folded, it is parallel to the door body 100. It should be noted that in the specific implementation, the workbench 4 is installed on the inside of the door body, facing the operating port 2, so that when the workbench 4 is unfolded, the operator can directly contact the workpiece on the workbench 4 through the operating port 2, which is convenient for sandblasting operations. When the workbench 4 is fully unfolded, the position of the operating port 2 should be roughly parallel to and facing the plane after the workbench 4 is unfolded, so as to facilitate the prevention of workpieces and facilitate manual operation. The foldable workbench 4 of this structure can be quickly switched to a different use mode according to different work requirements, which not only supports the automated sandblasting process but also facilitates manual operation, thereby improving the versatility and adaptability of the equipment.

[0024] like Figure 1-Figure 3 As shown, specifically, a cylinder 5 is installed on the outside of the door body 100 and is located above the observation window 1. The cylinder 5 includes a rotating shaft 51 with one end extending into the door body 100. The automatic wiper 3 is fixedly mounted on the rotating shaft 51 and can swing under the drive of the rotating shaft 51. The rotating shaft 51 is fixedly installed on the inner wall of the door body 100 through a fixing seat 52.

[0025] As described above, during the specific implementation, the cylinder 5 of this case is connected to an external air pump to provide a power source for the cylinder 5, thereby driving the rotating shaft 51 to rotate, and the rotating shaft 51 drives the automatic wiper 3 to swing left and right on the observation window 1 to maintain the cleanliness and transparency of the observation window, thereby ensuring that the operator can clearly see the internal sandblasting process at any time. Because during the sandblasting operation, the abrasive and dust ejected at high speed will be deposited on the observation window 1, forming a layer of dirt that blocks the line of sight, which not only affects the operator's field of vision, but also may bring safety risks, because the operator needs to monitor the status of the workpiece and the operation of the sandblasting machine at all times. The automatic wiper ensures that the operator can continue to have good visibility by periodically clearing the dust and abrasive on the observation window. It can effectively ensure that when the workpiece is manually sandblasted, the sandblasting is uniform, avoiding excessive sandblasting or insufficient sandblasting, and can also promptly detect any possible technical or safety problems.

[0026] like Figure 1-Figure 3As shown, specifically, the observation window 1 of this case includes a mounting frame 11 arranged on the outside of the door body 100, and a transparent window 12 installed in the mounting frame 11. The mounting frame 11 is used to fix the transparent window 12 on the door body 100. The lower end of the mounting frame 11 is rotatably connected to the door body 100 through the first hinge 13. The upper end of the mounting frame 11 is provided with a connecting portion 111, and the connecting portion 111 is provided with a first screw hole 112. The door body 100 is provided with a second screw hole 101. In specific implementation, the connecting portion 111 is symmetrically arranged. The setting position of the second screw hole 101 corresponds to the position of the first screw hole 112 when it is installed and fixed on the door body 100, so as to facilitate the threaded connection between the two. The user only needs to pass the bolt through the first screw hole 112 and the second screw hole 101 to connect and fix the two, which is convenient for disassembly and assembly, and the connection is stable. The design of this structure in this case is convenient for replacing the transparent window 12 when the transparent window 12 is damaged or the transparency is insufficient. The lower end of the installation frame 11 is rotatably connected to the door body 100 through the first hinge 13. The staff only needs to remove the bolts installed in the first screw hole 112 and the second screw hole 101 to rotate the installation frame 11 down, which is more convenient for replacing the transparent window 12. In order to ensure the connection and rotation stability between the installation frame 11 and the door body 100, two first hinges 13 are provided in the specific implementation.

[0027] like Figure 1-Figure 3 As shown, further, a second hinge 102 is provided on the left side of the door body 100 in this case. In specific implementation, the door body 100 is connected to the sandblasting machine through the second hinge 102. In order to ensure the connection and rotation stability between the door body 100 and the sandblasting machine, two second hinges 102 are provided. An articulated handle lock 103 for locking / unlocking and thus opening and closing the door body 100 is provided on the right side of the door body 100. The user can open and close the door body 100 of the sandblasting machine through the articulated handle lock 103, and the user can lock or unlock the door by pressing or lifting the handle, so as to operate the inside of the sandblasting machine.

[0028] like Figure 1-Figure 3 As shown, further, a plurality of through holes 41 are evenly formed on the workbench 4. The provision of the through holes 41 can reduce the accumulation of materials on the workbench 4, discharge excess waste, and enable the sandblasting medium to cover the workpiece surface more evenly, thereby improving the uniformity and efficiency of sandblasting.

[0029] like Figure 1-Figure 3As shown, specifically, two fixing plates 6 are symmetrically arranged at both ends of the inner side of the door body 100. In the specific implementation, for stable connection, the fixing plates 6 can be welded and fixed to the inner side of the door body. A connecting plate 7 is connected to each fixing plate 6, and a plurality of first connecting holes 61 are arranged on the fixing plate 6, and a plurality of second connecting holes 71 are arranged on the connecting plate 7. The workbench 4 is movably arranged between the two connecting plates 7 through a sliding mechanism. In the specific implementation, the number of the first connecting holes 61 and the second connecting holes 71 can be set according to demand. The user only needs to use bolts to pass through the first connecting holes 61 and the second connecting holes 71 to connect and fix the fixing plate 6 and the connecting plate 7. This structure realizes a detachable connection between the fixing plate 6 and the connecting plate 7, thereby realizing a detachable connection between the workbench 4 and the door body, which is convenient for disassembly and assembly. When the user does not use the workbench or performs automatic sandblasting, the workbench 4 can be removed to eliminate the negative impact of the workbench 4 on the sandblasting machine. The user can also adjust the height of the workbench to meet the sandblasting requirements of different workpieces by adjusting the installation position of the first connecting hole 61 relative to the second connecting hole 71, and can also be suitable for door bodies with different structures.

[0030] like Figure 1-Figure 3 As shown, specifically, the sliding mechanism includes a slide groove 72 opened on each connecting plate 7, and a first connecting shaft 42 provided at both ends of the workbench 4 and slidably connected to the slide groove 72. Specifically, the slide groove is opened on the connecting plate 7 along the vertical direction of the connecting plate 7, and the first connecting shaft 42 is slidably connected to the slide groove 71. When the workbench 4 is folded and unfolded, the first connecting shaft 42 always slides up and down in the slide groove 71.

[0031] The workbench 4 is also provided with a second connecting shaft 43 on both sides, and each connecting plate 7 is provided with a third connecting shaft 73 located below the slide groove 72. A support rod 8 is rotatably sleeved on each second connecting shaft 43, and the other end of the support rod 8 is rotatably sleeved on the third connecting shaft 73. The support rod 8 is provided to connect the workbench 4 and the connecting plate 7, so as to more conveniently realize the folding and unfolding of the workbench 4 relative to the connecting plate 7. The support rod 8 can automatically adjust the angle with the movement of the workbench 4, provide necessary support for the movement of the workbench 4, and maintain the stability of the structure. Among them, the support rod 8 can effectively support the workbench 4 when the workbench 4 is fully unfolded, so as to ensure the stability of the workbench 4 in the fully unfolded state, thereby effectively ensuring the stability of the workpiece on the workbench 4. At the same time, the support rod 8 realizes the linkage effect of the movement and support of the workbench 4, ensuring that the workbench 4 can maintain good balance and stability whether it is in the unfolded or folded state. The slide groove 72 includes a long groove 721 for the first connecting shaft 42 to be slidably connected therein, and a hook groove 722 in which the first connecting shaft 42 is limited and fixed when the workbench 4 is fully unfolded, and the hook groove 722 is located at the bottom end of the long groove 721. As shown in the figure, the hook groove 722 is in a hook shape as a whole, and the setting of the long groove 721 enables the workbench 4 to move smoothly along the set direction. When the workbench 4 is fully unfolded, the first connecting shaft 42 slides from top to bottom in the long groove 721 until it reaches the hook groove 722, and then changes the sliding direction to enter the hook groove 722, and is limited and fixed on the hook groove 722 to prevent the workbench 4 from slipping off and preventing the workbench 4 from accidentally moving. At the same time, the support rod 8 supports the workbench, which effectively ensures the stability of the workbench 4 in the fully unfolded state. Through the above design, the sliding mechanism of the present invention not only realizes the smooth movement of the workbench, but also ensures that the workbench 4 is firmly fixed at any position, greatly improving the convenience and safety of operation, and is suitable for occasions where the position of the workbench needs to be frequently adjusted.

[0032] like Figure 1-Figure 3 As shown, further, each connecting plate 7 is provided with a slot 74 for the second connecting shafts 43 at both ends of the workbench 4 to be inserted into when the workbench 4 is folded. The slot 74 ensures the structural stability of the workbench 4 in the folded state, avoids unnecessary shaking, and enhances the overall reliability. Not only does it make the folding of the workbench 4 more complete and save the occupied space of the workbench 4 after folding, but also the structural stability of the workbench 4 in the folded state is ensured by the mutual locking of the slot 74 and the second connecting shaft 43.

[0033] The working principle of the 4-fold workbench in this case is as follows:

[0034] When the user needs to fold the workbench 4, first, the first connecting shaft 42 of the workbench 4 slides along the slide groove 72 until the first connecting shaft 42 enters the hook groove 722, and the workbench is in the most compact state. Then, the second connecting shaft 43 is aligned and inserted into the slot 74 on the connecting plate 7, thereby completing the folding.

[0035] When the workbench 4 needs to be unfolded, only the reverse operation is required. First, the engagement between the second connecting shaft 43 and the slot 74 is released. Then, the workbench 4 is slid out along the slide slot 72 by sliding the first connecting shaft 42 until the first connecting shaft 42 reaches the open end of the long slot 721. At this time, the workbench is fully unfolded.

[0036] As mentioned above, this case protects a sandblasting machine door, and all technical solutions that are the same or similar to this case should be shown to fall within the scope of protection of this case.
