[0037] The present invention provides a feed door for a denture processing device. To make the purpose, technical solution, and effects of the present invention more clear and explicit, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the present invention and are not intended to limit the present invention.

[0038] like Figures 1 to 7 As shown, a feed door for a denture processing equipment has a simple structure, low cost and easy operation. The feed door is installed on the denture processing equipment and is used to control the raw materials for denture processing to enter the denture processing equipment to meet the needs of dental production experiments of different scales. Specifically, the feed door of the denture processing equipment includes a bracket 1, a door body 2, a push-pull assembly 4 and a limit assembly 3. The bracket 1 is used to provide support for the door body 2. In this application, the bracket 1 is composed of two support rods. In other embodiments, other numbers of support rods can also be provided to strengthen the support for the door body 2. The door body 2 is slidably mounted on the bracket 1, and the opening and closing of the feed door are controlled by the sliding of the door body 2. Only when necessary, the door body 2 is slid to open the feed door, so that the raw materials can pass through the feed door into the denture processing equipment to be processed into dentures. The push-pull assembly 4 is installed on the door body 2. By pushing the push-pull assembly 4, the door body 2 slides along the bracket 1, thereby controlling the opening and closing of the feed door. When the door body 2 slides to a specific position, it is necessary to maintain the door body 2 in the current position, so as to keep the feed door open or closed for a certain period of time, so that when the feed door is open, the raw materials can pass through the feed door and enter the denture processing equipment; or when the feed door is closed, the materials are prevented from falling out of the feed door, so as to maintain the stable operation of the denture processing equipment in processing the raw materials to produce dentures. Therefore, the feed door of the denture processing equipment also includes a limit assembly 3, which is fixed to the bracket 1. The limit assembly 3 limits the range of the door body 2 sliding along the bracket 1, and at the same time keeps the door body 2 fixed in a specific position, so as to keep the feed door open or closed.

[0039] Further, in order to keep the door body 2 fixed in position when sliding to open the feeding door, avoid the door body 2 from sliding continuously to affect the opening of the feeding door, the limiting assembly 3 comprises a limiting baffle 31, which is installed on the bracket 1 and can also fix the relative position of the bracket 1, so as to avoid the bracket 1 from deviating to damage the feeding door of the false tooth processing equipment when the door body 2 slides. After the limiting baffle 31 is installed, when the push-pull assembly 4 pushes the door body 2 to slide, the push-pull assembly 4 is clamped into the limiting baffle 31, and the door body 2 is fixed at the current position and cannot slide along the bracket 1 any more, as shown in Figure 1 and Figure 7 The door body 2 and the bottom keep a certain space, so that the raw materials can enter the false tooth processing equipment through the feeding door at this time.

[0040] Specifically, in order to enable the push-pull assembly 4 to be clamped into the limiting baffle 31 when the door body 2 slides to a specific position, the push-pull assembly 4 comprises a sliding block 41 and a limiting pin 42, as shown in Figure 5 The sliding block 41 is in a C shape, so as to facilitate the manual operation of the sliding block 41 by the operator, push the sliding block 41 to make the door body 2 slide, or move the sliding block 41 towards the door body 2 to clamp the limiting pin 42 into the limiting baffle 31 to fix the position of the door body 2, and the sliding block 41 can also be moved away from the door body 2 to drive the limiting pin 42 to move out of the limiting baffle 31 to release the fixation of the position of the door body 2. The limiting pin 42 is installed on the sliding block 41, the end of the limiting pin 42 close to the sliding block 41 is in a cylindrical shape, and the end of the limiting pin 42 close to the door body 2 gradually narrows, so as to facilitate the limiting pin 42 to penetrate into the door body 2 and be clamped into the limiting baffle 31. In order to enable the limiting pin 42 to penetrate into the door body 2, the door body 2 is also provided with a placement hole 21, which is a circular hole. In order to enable the limiting pin 42 to be clamped into the limiting baffle 31, the limiting baffle 31 is provided with a limiting groove 311, so that when the sliding block 41 is pushed to slide towards the door body 2, the limiting pin 42 is clamped into the limiting groove 311, and the limiting groove 311 blocks the sliding of the limiting pin 42 towards the bottom of the feeding door, so as to fix the position of the door body 2 by clamping the door body 2 with the limiting pin 42, and the door body 2 cannot slide along the bracket 1 any more, so as to keep the position of the door body 2 fixed and keep the feeding door open.

[0041] As shown in Figure 5As shown, since the sliding block 41 needs to drive the limit pin 42 to move when the limit pin 42 is inserted into the limit groove 311 or when the limit pin 42 is moved out of the limit groove 311, in order to enable the sliding block 41 to move in the push-pull assembly 4, in this application, the push-pull assembly 4 also includes a push-pull arm 43, and the sliding block 41 is slidably installed in the push-pull arm 43. The inner cavity of the push-pull arm 43 is also C-shaped, so that the operator can operate the sliding block 41 to make the sliding block 41 slide in the push-pull arm 43. Therefore, when it is necessary to insert the limit pin 42 into the limit groove 311, push the sliding block 41 so that the sliding block 41 slides in the push-pull arm 43 in the direction close to the door body 2 until the limit pin 42 is inserted into the limit groove 311. When it is necessary to move the limit pin 42 out of the limit groove 311, push the sliding block 41 so that the sliding block 41 slides in the push-pull arm 43 in the direction away from the door body 2 until the limit pin 42 is moved out of the limit groove 311. Then, apply a force on the push-pull arm 43 so that the push-pull arm 43 drives the door body 2 to slide along the bracket 1, thereby adjusting the position of the door body 2 relative to the bracket.

[0042] When the limit pin 42 is inserted into the limit groove 311, in order to maintain the inserted state of the limit pin 42, it is prevented that when an external force acts on the door body 2, for example, an object hits the door body 2, the door body 2 pushes the limit pin 42, so that the limit pin 42 moves out of the limit groove 311 and releases the fixed state of the door body 2, causing the feed door to no longer remain in the open or closed state, affecting the operation of the denture processing equipment. Therefore, in the present application, in order to prevent the limit pin 42 from moving at will, the push-pull assembly 4 also includes a drive spring 44, one end of the drive spring 44 is installed on the side of the sliding block 41 away from the door body 2, and the other end of the drive spring 44 is installed on the side of the inner wall of the push-pull arm 43 facing the door body 2. That is, when the limit pin 42 is engaged in the limit slot 311, the driving spring 44 resists the sliding block 41. When the door body 2 is pushed by an external force to move the limit pin 42 away from the door body 2, the elastic force of the driving spring 44 resists the movement of the sliding block 41 and the limit pin 42, keeping the limit pin 42 engaged in the limit slot 311. Only when it is really necessary to remove the limit pin 42 from the limit slot 311 and allow the door body 2 to continue sliding, the sliding block 41 is manually pressed to apply a certain force to the sliding block 41 to move it away from the door body 2. The driving spring 44 is squeezed during the movement of the sliding block 41, and then the sliding block 41 can move away from the door body 2, driving the limit pin 42 to move out of the limit slot 311. The door body 2 is now released, and then the push-pull arm 43 is pushed to make the door body 2 slide along the bracket 1. When the door body 2 slides to a specific position and needs to be kept fixed, it is only necessary to loosen the sliding block 41. The sliding block 41 moves toward the door body 2 under the drive of the squeezed driving spring 44, so that the limit pin 42 moves to contact the limit baffle 31 and is stuck in the limit groove 311, thereby completing the fixation of the door body 2 and keeping the door body 2 in a specific position.

[0043] When the sliding block 41 is slidably installed in the push-pull arm 43, in order to prevent the sliding block 41 from falling out of the push-pull arm 43, the push-pull assembly 4 also includes a pressing block 45. The pressing block 45 is installed under the push-pull arm 43 to provide support for the sliding block 41, so that the sliding block 41 slides between the pressing block 45 and the push-pull arm 43, ensuring smooth sliding of the sliding block 41.

[0044] Normally, the bottom of the feed door is not in direct contact with the ground, so there is a certain amount of space between the bottom of the feed door and the ground. When the feed door is closed by sliding the door body 2, if the sliding range of the feed door is not limited, the door body 2 may slide out from under the bracket 1, causing the structure of the feed door to be damaged. Therefore, in this application, the limit assembly 3 also includes a number of limit bars 32, such as Figure 1 and Figure 6As shown, the limit stop rod 32 is installed at the top of the door body 2. In this embodiment, two limit stop rods 32 are installed at the top of the door body 2. When the door body 2 slides along the bracket 1, the limit stop rod 32 gradually approaches the limit stop plate 31 and contacts it, thereby preventing the door body 2 from continuing to slide toward the bottom of the feed door, and preventing the door body 2 from sliding out of the bottom of the bracket 1 while keeping the feed door closed. Correspondingly, the limit stop plate 31 is provided with a limit step 312 at the position where it contacts the limit stop rod 32. By allowing the limit stop rod 32 to abut against the limit step 312, the feed door is kept closed. After the operator feels that the limit stop rod 32 abuts against the limit step 312, the operator can release the push-pull arm 43 without having to confirm whether the feed door is closed by confirming the position of the door body 2, thereby improving the efficiency of operating the feed door.

[0045] In order to enable the door body 2 to slide smoothly along the bracket 1, a slide rail 11 is provided on the bracket 1, and a slide rod 22 is provided on the door body 2. The slide rod 22 is slidably mounted on the slide rail 11, thereby enabling the door body 2 to slide along the bracket 1. In other embodiments, a groove may be provided on the bracket 1, and a roller may be provided on the door body 2, and the door body 2 may be moved along the bracket 1 by allowing the roller to roll along the groove.

[0046] To sum up, when the feed door of the denture processing equipment in this application is needed to control the raw materials for denture production to enter the denture processing equipment, it is necessary to open the feed door first. At this time, press the sliding block 41 to make the sliding block 41 move away from the door body 2, and then push the push-pull arm 43 to make the door body 2 slide along the bracket 1, so that the door body 2 gradually moves away from the bottom of the feed door. When the door body 2 slides to the specified position, release the sliding block 41. Under the elastic force of the driving spring 44, the sliding block 41 moves toward the door body 2, driving the limit pin 42 installed at the front end of the sliding block 41 to move toward the door body 2, and finally making the limit pin 42 penetrate the door body 2 and get stuck in the limit groove 311, thereby fixing the position of the door body 2 through the cooperation of the limit pin 42 and the limit groove 311, ensuring that the door body 2 no longer slides along the bracket 1 and keeps the feed door open. When the feed door needs to be closed, the sliding block 41 is pressed again to move the sliding block 41 away from the door body 2, driving the limit pin 42 to move out of the limit groove 311, releasing the fixation of the door body 2, and then pushing the push-pull arm 43 to make the door body 2 slide along the bracket 1 again until the limit stop rod 32 contacts the limit step 312, thereby keeping the feed door closed.

[0047] It should be understood that the application of the present invention is not limited to the above examples. For ordinary technicians in this field, they can make improvements or changes based on the above description. All these improvements and changes should fall within the scope of protection of the claims attached to the present invention.
