Description

Technical Field

[0001] This application relates to the field of tobacco production equipment technology, specifically to a protective door adjustment device. Background Technology

[0002] The B25 and YB45 packaging units are models from the Italian company GD. They feature a synchronous suction airflow system for aluminum foil and a protective door for the paper path. The door panel is movable, with a rubber cam on the hinged side and a ball bearing on the base. When the door is closed, the holes on the cam and the ball bearing engage to lock the door. However, prolonged use can cause wear on these holes, leading to a design flaw that makes the movable door prone to locking failure during operation. This can result in the door not closing completely, causing aluminum foil blockage and movement. Adjusting the movable door requires disassembling the guide plate, and the repaired state is short-lived. The operation is complex, and maintenance is time-consuming and labor-intensive. Utility Model Content

[0003] The purpose of this application is to provide a protective door adjustment device to solve the defect in the prior art that the door panel cannot be effectively closed after long-term use.

[0004] To achieve the above objectives, this application employs the following technical solution: This application discloses a protective door adjustment device, which includes... First mounting base; the first mounting base is provided with a first locking element; A door panel, which is rotatably mounted on the first mounting base, and a second locking member is provided on the door panel; the first locking member and the second locking member are configured to be physically connected and fixed together; The first locking member and the second locking member are fixed, and a through cavity is formed between the door panel and the first mounting base.

[0005] In a further embodiment of this application, the first mounting base is provided with a guide plate, and the guide plate covers the extended path of the through cavity on the vertical projection surface of the first mounting base.

[0006] In a further embodiment, the mounting position of the guide plate is adjustable, the guide plate is provided with a waist hole, and the guide plate is fixed to the first mounting base by bolts.

[0007] In a further embodiment, the guide plate has a slope on the side away from the door panel.

[0008] In a further embodiment of this application, the first locking member is a first magnet, the second locking member is a second magnet, and the first locking member and the second locking member are magnetically attracted and fixed together.

[0009] In a further embodiment of this application, a second mounting base is fixed on the first mounting base, and a movable component is mounted on the second mounting base via a pivot, wherein the door panel is detachably mounted on the movable component.

[0010] In a further embodiment, a torsion spring is fitted onto the rotating shaft, with each end of the torsion spring correspondingly connected to the movable component and the first mounting base.

[0011] In a further embodiment, the door panel is provided with a positioning groove, and the door is positioned and installed on the movable part through the positioning groove.

[0012] In a further embodiment of this application, the door panel is made of a transparent material.

[0013] The beneficial effects of this application are as follows: This application provides first and second locking components. When the door panel is closed, the two components lock together through physical properties. At this time, the door panel and the first mounting base can be firmly fixed. During production, the cavity between the door panel and the first mounting base will pass through aluminum foil paper transmitted from upstream processing. The locking force after the first and second locking components are fixed is much greater than the impact force of the aluminum foil on the door panel, ensuring that the door panel closes stably. At this time, the cavity can effectively limit the transmission path of the aluminum foil and prevent the drawbacks caused by the door not being fully closed.

[0014] The device also includes a torsion spring installed between the first mounting base and the moving part. During use, the torsion spring always provides a force to drive the door body to rotate toward the first mounting base, that is, it is in a compressed state during torsion, which further ensures the degree of closure of the door panel.

[0017] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use.

[0018] like Figure 1 and Figure 2 As shown, this embodiment discloses a protective door adjustment device, which includes a first mounting base 2 and a door panel 4; the first mounting base 2 is provided with a first locking member 21; the door panel 4 is rotatably mounted on the first mounting base 2, and the door panel 4 is provided with a second locking member 3; the first locking member 21 and the second locking member 3 are configured to be physically connected and fixed; wherein, the first locking member 21 and the second locking member 3 are fixed, and a through cavity is formed between the door panel 4 and the first mounting base 2.

[0019] When in use, install the protective door adjustment device in the corresponding position on the production line, open the door, pass the upstream cut aluminum foil through the cavity, place the aluminum foil in the correct position, and rotate to close the door until the first locking part 21 and the second locking part 3 make contact, ensuring that the door panel 4 is stably closed and preventing the door from having incomplete closure defects.

[0020] In one embodiment, the protective door adjustment device is specifically designed as follows.

[0021] In this embodiment, the first mounting base 2 is provided with a protruding plate on one side, and a threaded through hole is provided on the protruding plate. It can be quickly installed on the production line by bolts. The first locking member 21 uses the first magnet. In actual production, a mounting groove is opened on the first mounting base 2, and the first magnet is fixed in the mounting groove with an interference fit. The mounting groove and the hinge end of the first mounting base 2 are spaced apart. In this embodiment, the second locking member 3 uses the second magnet. The second magnet attracts the first magnet. It should be mentioned that a handle is fixed on the door. The end of the handle that movably contacts the first locking member 21 is integrally installed with the second locking member 3. The contact surfaces of the two magnets are designed to be flat.

[0022] Combined with appendix Figure 1 and Figure 3 In this embodiment, a second mounting base 6 is fixed on one side of the first mounting base 2. The area of ​​the second mounting base 6 is much smaller than that of the first mounting base 2. A movable part 5 is mounted on the second mounting base 6 through a rotating shaft. The movable part 5 is fixed to the door body. In order to facilitate the positioning and fixing of the movable part 5 and the door body, a positioning groove 41 is reserved during the actual installation of the door body. The cross section of the positioning groove 41 matches the cross section of the movable part 5. The movable part 5 is placed in the positioning groove 41 and fixed by tightening bolts. In a further embodiment, a torsion spring is sleeved on the rotating shaft of the first mounting base 2. The two ends of the torsion spring are connected to the movable part 5 and the first mounting base 2 respectively. It is worth mentioning that after the torsion spring is installed, when the door is closed, the torsion spring still maintains the tendency to rotate and close the door. When the torsion spring is used, the first locking part 21 and the second locking part 3 use the form of buckle and slot. Although the buckle and slot structure will wear out after long-term use, the effective use time of stable door closure can be greatly increased under the support of the torsion spring yield force.

[0023] As attached Figure 2 In this embodiment, the first mounting base 2 is equipped with a guide plate 1 made of stainless steel. The guide plate 1 has a slope on the side away from the door panel 4. The guide plate 1 covers the extended path of the cavity on the vertical projection surface of the first mounting base 2, and guides and limits the aluminum foil entering this structure during production. In the design, the mounting position of the guide plate 1 is adjustable. Specifically, a pair of waist holes 11 can be set at intervals on the guide plate 1. The guide plate 1 is fixed to the first mounting base 2 by bolts. The guide plate 1 can be fine-tuned by switching the fastening position on the waist holes 11.

[0024] In some embodiments, the door panel 4 is made of a transparent material, such as plexiglass or transparent plastic. After the device is put into use, the transmission status of the aluminum foil can be observed in a transparent manner, and abnormalities can be detected in a timely manner.

[0025] In practical use, a pair of conveyor belts can be rotatably installed on the first mounting base 2 along the cavity penetration line to improve the transmission power of the aluminum foil. Adjusting the installation position of the guide plate 1 to be closest to the position after the upstream aluminum foil cutter effectively improves the conveying of the aluminum foil, preventing the door from springing open due to foil bending during the process, and further preventing blockages caused by foil bending that could lead to equipment shutdown. It effectively prevents the door from opening without manual external force, has strong self-locking capability, and effectively prevents the protective door from springing open.
