Description

Technical Field

[0001] This utility model relates to the field of filling equipment technology, and in particular to an opening and closing door mechanism on a filling machine. Background Technology

[0002] In production, filling machines are used to fill self-spraying paints, cosmetics, coatings, and other products. These machines process the media using special methods and then fill them under high pressure. Their applications are very wide, including mold making, industrial machinery, toys, handicrafts, musical instruments, buildings, steel structures, advertising, signage, graffiti, and many other industries.

[0003] The filling machine casing includes a base, side panels, a top cover, and a door panel. The door panel is hinged to the front side of the cylinder body via a hinge post and opens by rotation. During opening, it typically rotates more than 90 degrees, and when fully opened, it rotates 180 degrees or more. The rotating area during the door panel opening process forms a circular region with the hinge post as the center and the door panel width as the radius. This traverses a large space, requiring a significant amount of space in front of the filling machine, which is a considerable space requirement in many applications. Since it is primarily used in industrial production, where space is already limited in integrated manufacturing, improvements to the door panel are necessary. Utility Model Content

[0004] To address the aforementioned issues, this utility model aims to provide an opening and closing door mechanism for a filling machine, which reduces the area the door panel traverses during opening, thus saving space in front of the filling machine.

[0005] The technical solution of this utility model is an opening and closing door mechanism on a filling machine, including a base and a top cover, and three side plates (left, right, and rear) connected between the two. An opening area is formed in front of the left and right side plates, and a door panel is provided in the opening area. The key feature is that: the top surface of the base and the bottom surface of the top cover are provided with insertion holes at the front position, and a hinge column is installed in the insertion hole. A first connecting rod is hinged to the bottom of the hinge column, and the other end of the first connecting rod is hinged to the bottom surface of the door panel. A second connecting rod is hinged to the top of the hinge column, and the other end of the second connecting rod is hinged to the top surface of the door panel. A third connecting rod is hinged to the bottom surface of the top cover, and the other end of the third connecting rod is hinged to the top surface of the door panel. The first, second, and third connecting rods are parallel to each other. The door panel opens and closes through the rotation and translation trajectory of the above three connecting rods.

[0006] Preferably, the top surface of the hinge post is provided with a mounting hole, and a compression spring and a plug rod are provided in the mounting hole. The top of the hinge post has a vertically extending slotted hole that passes through the mounting hole. The bottom of the plug rod has a horizontally extending threaded hole, and a screw is threaded into the threaded hole. The screw extends out from the slotted hole. When the screw is moved, it compresses the plug rod to move downward against the spring force. After the screw is released, the plug rod is pushed upward into the insertion hole on the bottom surface of the top cover under the action of the spring force. During the up and down movement of the plug rod, the screw moves up and down along the slotted hole.

[0007] Preferably, bushings are installed in the insertion holes on the top surface of the base and the bottom surface of the top cover, and the top end of the insertion rod and the bottom end of the hinge post are both inserted into the bushings.

[0008] Preferably, the top and bottom surfaces of the door panel are provided with insertion holes, and bushings are provided in the insertion holes. The outer ends of the first connecting rod, the second connecting rod, and the third connecting rod are all hinged by inserting the hinge rods into the bushings of the insertion holes of the door panel.

[0009] Preferably, the top of the door panel is connected to a horizontally arranged upper end plate, the bottom of the door panel is connected to a horizontally arranged lower end plate, the outer ends of the first and third connecting rods are both connected to the upper end plate, the outer end of the second connecting rod is connected to the lower end plate, and the insertion hole and bushing are both arranged on the upper end plate and the lower end plate.

[0010] Preferably, the door panel is provided with a handle.

[0011] This invention, through the setting of three connecting rods, ensures that the door panel opens and closes along a trajectory of rotation and translation according to the constraints of the three connecting rods during the opening process. This can significantly reduce the area swept by the door panel during the opening process and save space in front of the filling machine. Attached Figure Description

Detailed Implementation

[0013] The present invention will now be described in further detail with reference to the accompanying drawings.

[0014] like Figures 1 to 5 As shown, this utility model provides an opening and closing door mechanism for a filling machine, including a base 1 and a top cover 2, and three side plates 3 connected between the two. An opening area is formed in front of the two side plates 3, and a door panel 4 is provided in the opening area. The key feature is that: the top surface of the base 1 and the bottom surface of the top cover 2 are provided with insertion holes at the front position, and a hinge pin 5 is installed in the insertion holes. The bottom of the hinge pin 5 is hinged to a first connecting rod 6, and the other end of the first connecting rod 6 is hinged to the bottom surface of the door panel 4. The top of the hinge pin 5 is hinged to a second connecting rod 7, and the other end of the second connecting rod 7 is hinged to the top surface of the door panel 4. The bottom surface of the top cover 2 is hinged to a third connecting rod 8, and the other end of the third connecting rod is hinged to the top surface of the door panel 4. The first connecting rod 6, the second connecting rod 7, and the third connecting rod 8 are parallel to each other. When the door panel 4 opens and closes, it is achieved by the rotation and translation trajectory of the above three connecting rods.

[0015] In the above scheme, the top surface of the hinge post 5 is provided with a mounting hole, and a compression spring 9 and a plug rod 10 are provided in the mounting hole. The top of the hinge post 5 is vertically provided with a strip hole that passes through the mounting hole. The bottom of the plug rod 10 is provided with a threaded hole 101, and a screw 11 is threaded into the threaded hole 101. The screw 11 extends out from the strip hole. When the screw 11 is moved, it presses the plug rod 10 downward against the spring force. After the screw 11 is released, the plug rod 10 is pushed upward into the insertion hole on the bottom surface of the top cover 2 under the action of the spring force. During the up and down movement of the plug rod 10, the screw 11 moves up and down along the strip hole.

[0016] In addition, bushings 12 are installed in the insertion holes on the top surface of the base 1 and the bottom surface of the top cover 2, and the top end of the insertion rod 10 and the bottom end of the hinge post 5 are both inserted into the bushings 12.

[0017] Specifically, the top and bottom surfaces of the door panel 4 are provided with insertion holes, and bushings 12 are provided in the insertion holes. The outer ends of the first connecting rod 6, the second connecting rod 7, and the third connecting rod 8 are all hinged by inserting the hinge rod 13 into the bushings 12 of the insertion holes of the door panel 4.

[0018] Furthermore, the top of the door panel 4 is connected to a horizontally arranged upper end plate 14, and the bottom surface of the door panel 4 is connected to a horizontally arranged lower end plate 15. The outer ends of the first connecting rod 6 and the third connecting rod 8 are both connected to the upper end plate 14, and the outer end of the second connecting rod 7 is connected to the lower end plate 15. The insertion hole and the bushing are both arranged at the upper end plate 14 and the lower end plate 15.

[0019] In addition, a handle 41 is provided on the door panel 4 to facilitate the opening and closing of the door panel 4.

[0020] This utility model achieves the following by setting three parallel connecting rods 6, 7, and 8 between the door panel 4, the top surface of the base 1, and the bottom surface of the top cover 2: the door panel 4 rotates around the first connecting rod 6 and the second connecting rod 7 during the opening and closing process, while its translational motion is restricted by the first connecting rod 6 and the third connecting rod 8 during the rotation process, ultimately presenting a trajectory that combines rotation and translation, eliminating the need to completely flip open and occupy a large area in front as in the past.

[0021] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the utility model. Any simple modifications, equivalent changes, or alterations made to the above embodiments based on the technical principles of the present utility model shall still fall within the scope of the technical solution of the present utility model.
