Abstract
Description
Technical Field
[0001] This utility model relates to a traction mechanism, and more particularly to a traction mechanism suitable for spraying parts of an injection molding machine. Background Technology
[0002] The main components of injection molding machines are all made of cast iron. Before the equipment leaves the factory, they must be painted to enhance the corrosion resistance of the casting surface, prevent rust, improve the appearance quality of the product, and enhance the brand image. There are two existing painting modes for large castings: centralized painting and assembly line painting. Assembly line painting mainly uses accumulation chains or roller beds as the transportation system and special tooling as the transport carrier to transfer and paint the parts to be painted.
[0003] Existing problems:
[0004] 1. The company produces a wide variety of machine models with a large range of products, varying greatly in size and weight. The heaviest single component can reach 25t, and the conventional accumulation chain and roller bed have high power requirements.
[0005] 2. Due to the limited layout of the workshop space (the location of each room), the travel distance between each workstation is inconsistent, making it difficult to control different trolleys to arrive at the same time with a single power source, which increases hardware costs. Utility Model Content
[0006] This invention provides a traction mechanism suitable for spraying parts of injection molding machines to overcome the shortcomings of existing technologies where a single power source is difficult to control different trolleys.
[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0008] This utility model discloses a traction mechanism suitable for spraying parts of an injection molding machine, including a trolley, which is installed above a trolley track. A traction chain plate is provided inside the trolley track, and the trolley is connected to the traction chain plate. The traction mechanism provides power to the trolley. Limit switches A and B are respectively provided at both ends of the trolley track. A lifting mechanism is provided near limit switch A to disengage the trolley from the traction chain plate.
[0009] Furthermore, the trolley includes a flatbed trolley, with several sets of flatbed trolley rollers installed on the bottom of both sides. A hook fixing box is installed on the bottom of the flatbed trolley by screws. A ball bearing bush is installed inside the hook fixing box. The trolley hook passes through the ball bearing bush and the hook fixing box. A hook adjusting nut is installed on the trolley hook to facilitate the adjustment of its height. Baffles are installed on the front and rear sides of the flatbed trolley.
[0010] Furthermore, the lifting mechanism includes a lifting cylinder and a guide mechanism located above it, the guide mechanism being used to prevent the trolley hook from interfering with the movement of the lifting cylinder.
[0011] Furthermore, the traction mechanism includes a traction cylinder, the output end of which is provided with a traction baffle, and the side of the traction cylinder near the traction baffle is provided with a push baffle, which is used to reconnect the trolley after it has detached from the traction chain plate.
[0012] Furthermore, the trolley hook completes the connection by having its protruding bottom portion misaligned and falling into the notch of the traction chain plate.
[0013] Furthermore, the traction baffle can be released or clamped by switching between a horizontal and a vertical state, thereby controlling the disconnection and connection of the vehicle hook and the traction chain plate.
[0014] The beneficial effects achieved by this utility model are:
[0015] 1. The trolley size is determined by the maximum size of the product, eliminating the need for complex positioning. It can be placed as needed to meet production requirements, making it convenient and efficient. The trolley hook structure is simple and easy to maintain.
[0016] 2. The trolley is powered by the traction chain and traction mechanism, and the resistance is rolling friction. Under heavy loads, the required traction force does not need to be significantly increased, thus saving hardware costs.
[0017] 3. The starting and stopping of the trolleys are controlled by the lifting mechanism, which solves the problem of inconsistent travel distances of different trolleys on the same power line without the need for segmented power supply, further saving hardware costs. Attached Figure Description

[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0025] Example 1
[0026] like Figure 1-4 As shown, a traction mechanism suitable for spraying parts of an injection molding machine includes a trolley 1, which is installed above a trolley track 5. A traction chain plate 4 is provided inside the trolley track 5, and the trolley 1 is connected to the traction chain plate 4. A traction mechanism 3 provides power to the trolley 1. Limit switches A6 and B7 are respectively provided at both ends of the trolley track 5. A lifting mechanism 2 is provided near the limit switch A6, which is used to disengage the trolley 1 from the traction chain plate 4.
[0027] The trolley 1 includes a flatbed 1.1. Several sets of flatbed rollers 1.2 are installed on the bottom of both sides of the flatbed 1.1. A hook fixing box 1.4 is installed on the bottom of the flatbed 1.1 by screws. A ball bearing bushing 1.5 is installed inside the hook fixing box 1.4. The trolley hook 1.6 passes through the ball bearing bushing 1.5 and the hook fixing box 1.4. A hook adjusting nut 1.3 is installed on the trolley hook 1.6 to facilitate the adjustment of its height. Baffles 1.7 are installed on the front and rear sides of the flatbed 1.1.
[0028] The lifting mechanism 2 includes a lifting cylinder 2.1 and a guide mechanism 2.2 located above it. The guide mechanism 2.2 can effectively prevent the trolley hook 1.6 from interfering with the movement of the lifting cylinder 2.1.
[0029] The traction mechanism 3 includes a traction cylinder 3.1, the output end of the traction cylinder 3.1 is provided with a traction baffle 3.2, and the side of the traction cylinder 3.1 near the traction baffle 3.2 is provided with a push baffle 3.3.
[0030] The upper surface of the flatbed 1.1 is a flat surface, and its size is slightly larger than that of the largest component.
[0031] Working process: The trolley 1 is placed on the trolley track 5. The trolley hook 1.6 hangs on the traction chain plate 4 due to its own weight. The spraying system is started, the traction chain plate 4 begins to move, and the protruding part at the bottom of the trolley hook 1.6 is misaligned and falls into the notch of the traction chain plate 4, pushing the trolley 1 to start moving.
[0032] When the trolley 1 moves to the corresponding work position, the trolley hook 1.6 touches the limit switch A6, the lifting mechanism 2 cylinder lifts the trolley hook 1.6, so that it is disengaged from the traction chain plate 4, the trolley 1 loses power and stops moving. After the work is completed, the lifting mechanism 2 resets, the trolley hook 1.6 falls down, and the trolley 1 continues to follow the traction chain plate 4.
[0033] As trolley 1 is about to detach from the traction chain plate 4 area, trolley hook 1.6 touches limit switch B7, traction cylinder 3.1 lifts, traction baffle 3.2 rotates clockwise to a vertical position, clamps baffle 1.7 and begins to move. After limit switch B7 loses signal, trolley hook 1.6 completely detaches from traction chain plate 4, trolley 1 is pulled by traction mechanism 3 to provide power and stops in place. After the traverse car is transferred to the position, traction mechanism 3 pushes trolley 1 with push baffle 3.3, trolley hook 1.6 touches limit switch B7, traction cylinder 3.1 resets, traction baffle 3.2 rotates counterclockwise to a horizontal position, releases baffle 1.7, trolley hook 1.6 enters the traction chain plate 4 area, power is switched, and after limit switch B7 loses signal, traction mechanism 3 resets and waits.
