Description

Technical Field

[0001] This utility model relates to the field of door closer manufacturing technology, and in particular, to a door closer housing vibratory cleaning device. Background Technology

[0002] A door closer is a hydraulic automatic door closing device that drives the door to close via an internal spring and hydraulic system. Its core principle is based on a gear-driven rack and pinion system that compresses the spring. Hydraulic oil, passing through a throttle valve, acts as a buffer, allowing for adjustable closing speed. Its main functions include automatic door closing, door protection, reduced impact noise, and fire and smoke isolation. It is widely used in public buildings, residences, and safety passages. Common types include externally mounted, top-mounted, and floor-spring (bottom-mounted) types.

[0003] During the manufacturing process, the door closer housing needs to be polished and ground using a vibratory cleaning device. For example, after the door closer housing is placed into the hopper of the vibratory cleaning device, the device's vibratory motor drives the door closer housing and the grinding balls inside the hopper to vibrate together. Polishing is achieved through the relative friction between the grinding balls and the door closer housing. During discharge, the door closer housing rises along the screen plate under the action of vibration, while the grinding balls pass through the screen plate and fall back into the hopper. However, due to the special structure of the door closer housing, grinding balls may remain inside the housing. This requires significant manual effort to remove the grinding balls from the housing later, reducing the production efficiency of the door closer. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a door closer housing vibratory cleaning device.

[0005] The objective of this utility model is achieved through the following technical solution: A door closer housing vibratory cleaning device includes a body with a hopper filled with abrasive material. The body also has a vibration source. A screen plate is installed inside the hopper. The screen plate includes an upwardly inclined feeding section and a discharge section connected to the feeding section. The discharge section is adapted to have a lateral tilt angle so that the door closer housing entering the discharge section slides along a trajectory intersecting the discharge direction.

[0006] A guide plate is connected between the feeding section and the discharge end.

[0007] The feed end of the guide plate is fixed to the discharge end of the feed section. A slot is provided at the feed end of the discharge section, and a clip is constructed at the discharge end of the guide plate. The clip is inserted into the slot.

[0008] The feed end of the discharge section is also equipped with an air nozzle, which is adapted to spray airflow towards the bottom of the discharge section in an inclined direction.

[0009] The air nozzle is connected to the air supply system.

[0010] A bladder is provided on the end face of the feed end of the discharge section, and the bladder is connected to the air nozzle through a pipe.

[0011] A buffer pad is provided at the bottom of the inclined section of the discharge section.

[0012] The beneficial effects of this invention are as follows: the door closer housing gradually moves towards the discharge section via the feeding section. During this process, the grinding balls inside the cavity of the door closer housing, whose axis is basically parallel to the discharge direction, are discharged under the action of vibration. After the door closer housing enters the discharge section, the grinding balls inside the cavity of the door closer housing, whose axis is basically parallel to the inclination direction of the discharge section, are discharged under the action of vibration. Compared with the prior art, this invention utilizes two feeding and discharge sections with different inclination directions to achieve complete discharge of grinding balls from the door closer housing, thereby reducing manual labor intensity and improving the production efficiency of the door closer.

[0015] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] like Figure 1 , Figure 2 , Figure 3 As shown, a door closer housing vibratory cleaning device includes a body 1 with an upward-opening hopper 2. For example, a door closer housing to be polished can be placed into the hopper 2 and mixed with abrasive material (not shown) in the hopper 2 under the vibration of a vibration source. The abrasive material is preferably abrasive beads, and vibratory cleaning is achieved by utilizing the friction between the abrasive beads and the door closer housing.

[0017] After the gate closer housing completes its vibratory polishing, the movable part of the screen plate 3 can be installed onto the hopper 2. Subsequently, under the action of vibration, the gate closer housing gradually rises onto the screen plate 3 through this movable part, finally completing the discharge. During this process, the grinding balls will fall back into the hopper 2 through the screen holes of the screen plate 3.

[0018] Regarding how the door closer housing climbs and feeds along the sieve plate 3, it can be done using a vibrating plate in the prior art, which will not be elaborated in this disclosure.

[0019] For example, the screen plate 3 may specifically include a feeding section 4 and a discharging section 5, wherein the feeding section 4 is inclined upwards, thereby guiding the door closer housing to move towards the discharging section 5. The discharging section 5 is adapted to have a laterally inclined posture. The feeding section 4 and the discharging section 5 together form a discharging direction for expelling the door closer housing. The term "lateral" refers to the direction along both sides of the discharging direction, thus "lateral" and the discharging direction can be defined as intersecting.

[0020] When the door closer housing enters the feeding section 4, due to the different postures of the door closer housings, only the grinding balls in the cavity of the door closer housing whose axis is basically parallel to the discharge direction will be discharged under the action of vibration. When the door closer housing enters the discharge section 5, the door closer housing will slide to the bottom side of the inclined direction of the discharge section 5 under the action of gravity. At this time, the grinding balls in the cavity of the door closer housing whose axis is basically parallel to the inclined direction of the discharge section 5 will be discharged under the action of vibration.

[0021] In addition, when the door closer housing, whose axis is basically parallel to the inclined direction of the discharge section 5, slides to the bottom, the door closer housing will tend to sway more due to the convex shape of its end. This causes the side of the door closer housing to abut against the bottom of the inclined direction of the discharge section 5. At this time, the axis of the door closer housing will be basically parallel to the discharge direction. As the feeding proceeds, the grinding balls in the cavity of the door closer housing are more easily discharged completely.

[0022] In a preferred embodiment, the discharge section 5 may include a connecting portion and a screen portion disposed at the bottom of the connecting portion, wherein the screen portion is laterally inclined. After the gate closer housing is discharged into the discharge section 5, the housing slides down along the screen portion and abuts against the connecting portion. For example, a buffer pad 11 may be provided on the side wall of the connecting portion to avoid impact damage to the gate closer housing.

[0023] In some embodiments, a guide plate 6 may be connected between the feeding section 4 and the discharging section 5 to guide the door closer housing more smoothly into the discharging section 5. In a specific example, the feeding end of the guide plate 6 is fixed to the discharging end of the feeding section 4 by bolts or other fasteners. Preferably, a slot 7 is provided at the feeding end of the discharging section 5, and a corresponding retaining strip 8 is constructed at the discharging end of the guide plate 6. During the vibratory cleaning process of the door closer housing, the feeding section 4 can be removed from the discharging section 5. When discharge is required, the retaining strip 8 of the guide plate 6 can be inserted into the slot 7, and the end of the feeding section 4 away from the guide plate 6 extends downward into the hopper 2.

[0024] In addition, an air nozzle 9 can be installed on the feed end of the discharge section 5. For example, the air nozzle 9 can be connected to an air supply system such as an air pump. In particular, when the door closer housing, whose axis is basically parallel to the inclination direction of the discharge section 5, slides down to, for example, abut against the connecting part, the air nozzle 9 can spray an airflow for the door closer housing, thereby actively driving the door closer housing to deflect.

[0025] In another configuration, a bladder 10 connected to the air nozzle 9 via a pipe can be installed on the discharge end of the discharge section 5. When the door closer housing falls into the discharge section 5, the door closer housing will impact the bladder 10, causing the air in the bladder 10 to be ejected through the air nozzle 9 to form the aforementioned airflow, thereby eliminating the need for additional power supply from the air supply system.

[0026] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
