Description

Technical Field

[0001] This utility model relates to the field of paint packaging, and in particular to a novel anti-drip paint filling device. Background Technology

[0002] Existing paint filling equipment mainly includes a frame, a sliding frame mounted on the frame, a first cylinder mounted on the frame for controlling the up-and-down movement of the sliding frame, a filling valve assembly (including a filling nozzle and a filling valve) fixed to the outside of the sliding frame, a receiving box located directly below the filling valve assembly, and a second cylinder for controlling the forward / backward movement of the receiving box. Its working principle is as follows: During filling, the receiving box is first retracted by the second cylinder, and the filling valve assembly is moved towards the paint bucket by the first cylinder until the filling nozzle enters the paint bucket, preventing paint splashing during filling. Then, the filling valve of the filling valve assembly is opened to fill the paint bucket. After filling, the filling valve assembly is reset by the first cylinder. After resetting, the receiving box extends by the second cylinder to receive paint dripping from the filling nozzle, preventing environmental pollution. Existing paint filling equipment has the following drawbacks:

[0003] The filling valve assembly and the receiving box are independently controlled by the first cylinder and the second cylinder, respectively, and the linkage action of the two cylinders needs to be set, which requires a high level of electrical control skills from the technicians. Furthermore, mechanical failure of the second cylinder or failure of the electrical control that controls its action may cause the receiving box to fail to retract, resulting in filling leakage.

[0004] Based on this, this application provides a novel anti-drip paint filling device that uses mechanical linkage to control the extension and retraction of the receiving box to solve the above problems. Utility Model Content

[0005] This invention aims to solve the technical problems existing in the prior art. To this end, this invention provides a novel anti-drip paint filling device, which realizes the telescopic movement of the receiving box through mechanical linkage control.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A novel anti-drip paint filling device is provided, comprising a frame, a sliding frame slidably mounted on the frame, a linear actuator mounted on the frame for controlling the up-and-down movement of the sliding frame, a filling valve assembly fixed to the outside of the sliding frame, a receiving box located directly below the filling valve assembly, and a drive mechanism for controlling the forward / backward movement of the receiving box; the drive mechanism includes crossbeams located at the front and rear ends of the frame, a connecting shaft that movably passes through the crossbeams and connects to the receiving box, a fixed wedge fixed on the connecting shaft, a return spring sleeved on the connecting shaft with its two ends respectively abutting against the crossbeams and the fixed wedge, and a movable wedge mounted on the sliding frame for pressing the fixed wedge; both the movable wedge and the fixed wedge are right-angled trapezoids, and the movable wedge has a clearance groove in the middle to avoid the connecting shaft.

[0008] In some alternative embodiments, both the movable wedge and the fixed wedge are right-angled trapezoids, and the distance between the right surface of the fixed wedge and the left surface of the movable wedge is greater than the distance between the outer edge of the receiving box and the inner edge of the filling nozzle of the filling valve assembly.

[0009] In some alternative embodiments, the connecting shaft is provided with a groove along its length, and the inner wall of the through hole of the crossbeam is provided with a rib that mates with the groove.

[0010] In some alternative embodiments, the movable wedge is a hollow structure made of sheet metal with a weld resistance coating.

[0011] In some alternative embodiments, a limiting baffle is provided at the end of the connecting shaft away from the receiving box.

[0012] In some alternative implementations, the linear actuator is any one of a pneumatic cylinder, a hydraulic cylinder, or an electric push rod, and is fixedly mounted on the top plate of the frame.

[0013] In some alternative embodiments, an arc-shaped limiting plate for limiting the paint bucket is provided on the frame directly below the filling valve assembly.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The drive mechanism designed in this utility model can use a linear actuator to control the sliding frame to move downward during filling, thereby driving the movable wedge to squeeze the fixed wedge, which in turn causes the connecting shaft to move to the left, allowing the receiving box to retract without affecting the filling process. After filling is completed, the sliding frame moves upward, and the connecting shaft and the receiving box are reset under the action of the return spring, which plays a role in receiving material and preventing dripping. This design realizes the extension and retraction movement of the receiving box through mechanical linkage, reducing the failure rate of the equipment and also reducing the requirements for the electrical control level of the technicians.

[0027] Example 1

[0028] As attached Figure 1 As shown, this embodiment provides a novel anti-drip paint filling device, including a frame 1, a sliding frame 2, a linear actuator 3, a filling valve assembly 4, a receiving box 5, and a drive mechanism 6, wherein:

[0029] The sliding frame 2 is slidably mounted on the frame 1. In one embodiment, the frame 1 is provided with two guide rods 1.1, and the back sides of the sliding frame 2 are respectively provided with guide sleeves that slide in cooperation with the two guide rods, so that the sliding frame 2 can move up and down along the guide rods 1.1.

[0030] The linear actuator 3 is any one of a pneumatic cylinder, a hydraulic cylinder, or an electric push rod. In this embodiment, a pneumatic cylinder is preferred. It is fixedly installed on the top plate of the frame 1, and its push rod is fixedly connected to the sliding frame 2. The sliding frame can be controlled to move up and down by the pneumatic cylinder.

[0031] The filling valve assembly 4 is fixedly installed on the sliding frame 2. The filling valve assembly 4 includes a filling nozzle 4.1, a hose 4.2 connected to the filling nozzle, and a filling valve 4.3 that controls the opening / closing of the filling nozzle. The hose 4.2 passes through the sliding frame 2 and is connected to the paint supply system.

[0032] The receiving box 5 is located directly below the filling nozzle 4.3 and is used to receive the paint dripping from the filling nozzle. In order to enable the receiving box to extend and retract through a mechanical structure controlled by a cylinder, this embodiment designs a drive mechanism 6.

[0033] The drive mechanism 6 includes a crossbeam 6.1, a connecting shaft 6.2, a fixed wedge 6.3, a movable wedge 6.4, and a return spring 6.5. Specifically: two crossbeams 6.1 are fixedly installed at the front and rear positions of the frame 1, serving as support for the entire drive mechanism; one end of the connecting shaft 6.2 is fixedly connected to the receiving box 5, and the other end passes through a through hole on the crossbeam 6.1, allowing the connecting shaft 6.2 to move freely along its axial direction; the fixed wedge 6.3 is fixedly installed on the connecting shaft 6.2 (preferably secured with a set screw), with its inclined surface facing upwards; the movable wedge 6.4 is fixedly installed at the bottom of the sliding frame 2, with its inclined surface facing the fixed wedge 6.3 and abutting against it, used to compress the fixed wedge; the return spring 6.5 is fitted onto the connecting shaft 6.2, with its two ends abutting against the crossbeam 6.1 and the fixed wedge 6.3 respectively, and is used to reset the receiving box 5.

[0034] Preferred options are listed below. Figure 3 As shown, in this embodiment, both the movable wedge 6.4 and the fixed wedge 6.3 are right-angled trapezoids. The distance L1 between the right surface of the fixed wedge 6.3 and the left surface of the movable wedge 6.4 is greater than the distance L2 between the outer edge of the receiving box 5 and the inner edge of the filling nozzle 4.3 of the filling valve assembly. This design ensures that the distance the connecting axis moves to the left under the pressure of the movable wedge ensures that the receiving box avoids the movement path of the filling nozzle. Simultaneously, the height of the movable wedge should satisfy the condition that the filling nozzle does not interfere with the receiving box before it is fully retracted. After the receiving box is fully retracted, the movable wedge can continue to descend, at which point the left surface of the movable wedge contacts the right surface of the fixed wedge, thus maintaining the position of the receiving box while the filling nozzle continues to descend into the mouth of the paint bucket for filling.

[0035] To prevent the connecting shaft from interfering with the downward movement of the movable wedge, this embodiment provides a clearance groove 6.4.1 in the middle of the movable wedge 6.4 to allow the connecting shaft to pass.

[0036] Working principle: as shown in the appendix Figure 1 and attached Figure 3 As shown, when filling is required, the sliding frame descends under the control of the cylinder. The descending movable wedge presses against the fixed wedge, the connecting shaft moves to the left, and the receiving box also moves to the left until the left surface of the movable wedge is coplanar with the right side of the fixed wedge. At this point, the receiving box retracts completely, the sliding frame continues to descend, the receiving box remains in place, and the filling nozzle continues to descend into the mouth of the paint bucket, as shown in the attached diagram. Figure 2 As shown, the filling valve is then opened to complete the filling. After filling, the sliding frame is moved upward by the cylinder. When the left surface of the movable wedge is misaligned with the right surface of the fixed wedge, it continues to move upward. The fixed wedge is moved to the right by the spring force of the reset spring until the cylinder is fully retracted, and the receiving box is reset.

[0037] Preferably, the connecting shaft 6.2 has a groove (not shown in the figure) along its length, and the inner wall of the through hole of the crossbeam 6.1 has a rib (not shown in the figure) that mates with the groove. This design enables circumferential limiting of the connecting shaft and prevents rotation of the connecting shaft.

[0038] Preferably, the movable wedge 6.4 is a hollow structure made of plate weld resistance, as shown in the attached figure. Figure 1 As shown, this design reduces the weight of the movable wedge and saves raw materials.

[0039] Preferably, a limiting baffle 6.2.1 is provided at the end of the connecting shaft 6.2 away from the receiving box 5.

[0040] Preferably, an arc-shaped limiting plate 7 for limiting the paint bucket 10 is provided on the frame 1 directly below the filling valve group 4, which can play a role in positioning the paint bucket when it is placed.

[0041] It is worth noting that if the filling nozzle has not yet entered the paint bucket when it is moved to the lowest position during filling, the paint bucket can be raised with a pad so that the filling nozzle can be inserted into the bucket opening, thus preventing paint from splashing out of the bucket during the filling process.

[0042] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
