Description

Technical Field

[0001] This utility model relates to the field of knurling unloading technology, specifically an unloading device for a knurling machine. Background Technology

[0002] A knurling machine, also known as an ultrasonic knurling machine, ultrasonic embossing machine, or ultrasonic lace machine, is a device that uses ultrasonic principles and a knurling wheel of a specific shape to create knurling or embossing patterns on a material. The knurling pattern is determined by the shape of the knurling wheel. The machine can create different patterns simply by changing the knurling wheel. For example, during the production and processing of metal sheets, knurling machines are used to roll patterns onto the surface of the sheet to increase its friction, aesthetics, or connection strength. However, current metal sheet knurling machines require workers to be stationed at the discharge point to catch the finished metal sheet after knurling. This manual unloading method is time-consuming and labor-intensive. Therefore, we have proposed a discharge device for knurling machines to solve the above problems. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure, an embodiment of the present invention provides a material unloading device for a knurling machine, including a base plate 1, a frame 2 fixed to the top of the base plate 1, two support plates 3 fixed to the top of the frame 2, and two feeding rollers 4 connected between the two support plates 3 by bearings. Each feeding roller 4 has a sprocket 12 fixed to its surface, and the two sprockets 12 are connected by a chain 13, allowing one motor to simultaneously drive both feeding rollers 4 to rotate synchronously, thereby saving production costs. A bracket 5 fixed to the top of the base plate 1 is provided on one side of the frame 2, and a hydraulic cylinder 6 is fixed to the top of the bracket 5. The ejector end of the pressure cylinder 6 is slidably connected to the bracket 5, extending below it and fixed to a U-shaped plate 7. Four guide rods slidably pass through the top of the bracket 5, and the bottom ends of the guide rods 15 are fixedly connected to the top of the U-shaped plate 7, providing auxiliary support for the U-shaped plate 7 to ensure stability during its vertical movement. A receiving mechanism 8 is provided on the U-shaped plate 7. A transfer seat 9 is provided in the clearance groove at the top of the base plate 1. Two guide rails 16 are fixed to the top of the base plate 1, and two guide plates 17 adapted to the guide rails 16 are fixed to the bottom of the transfer seat 9, guiding the transfer seat 9. To ensure stability when placed below the receiving mechanism 8, a push handle 10 is fixed to the top of the transfer seat 9, and four universal self-locking wheels 11 are fixed to the bottom of the transfer seat 9. When using this knurling machine's unloading device, a knurling machine is installed on one side of the top unloading roller 4 of the base plate 1. First, the receiving mechanism 8 can be adjusted to a suitable receiving distance according to the width of the metal plate to be knurled. Then, after the knurling machine finishes knurling the metal plate, it will move onto the unloading roller 4. The motor is started to drive the unloading roller 4 to rotate. After the unloading roller 4 rotates, it can transport and move the metal plate onto the receiving mechanism 8. Then, the machine can be started. Hydraulic cylinder 6 drives U-shaped plate 7 to move down. After U-shaped plate 7 moves down, it will drive receiving mechanism 8 and knurled metal plate to move down. When the metal plate moves down to a suitable position above transfer seat 9, receiving mechanism 8 can be operated to release the restriction on the metal plate. Then the metal plate will fall onto transfer seat 9. This process is repeated to realize the automatic receiving and unloading of knurled metal plate. Later, when a certain number of metal plates are stacked on transfer seat 9, the push handle 10 and universal self-locking wheel 11 are installed on transfer seat 9, so the operator can easily move the knurled metal plate close to the ground.

[0024] like Figure 1 and Figure 4As shown, in some embodiments, the receiving mechanism 8 includes a bidirectional lead screw 801 rotatably connected between the inner walls of both sides of the U-shaped plate 7 via bearings. Both ends of the bidirectional lead screw 801 are threadedly connected to movable seats 802 whose surface threads are adapted to the screw's threads. Support shafts 803 are rotatably connected to the side walls of the movable seats 802 at equal intervals via bearings. Guide blocks 804 are fixed to the surface of each support shaft 803. Two limiting rods 805 are fixed between the inner walls of both sides of the U-shaped plate 7. The two movable seats 802 slide on the surfaces of the two limiting rods 805. In use, after the knurling is completed, the metal sheet is conveyed and moved onto the guide blocks 804 on both sides by the feeding roller 4. Under the action of the support shaft 803, the guide block 804 can rotate, thereby preventing it from scratching the surface of the metal plate. When the metal plate moves to the appropriate position, the motor is started to drive the bidirectional lead screw 801 to rotate. After the bidirectional lead screw 801 rotates, it will drive the two moving seats 802 to move outward at the same time. When the guide blocks 804 on both sides move in opposite directions, the restriction on the metal plate can be released, and then it can be stacked on the transfer seat 9. The limit rod 805 can limit the two moving seats 802, so that when the bidirectional lead screw 801 rotates, the moving seats 802 will not rotate synchronously with it.

[0025] like Figure 3 As shown, in some embodiments, the surface of the feeding roller 4 is fixed with an anti-slip protective roller sleeve 14, which is made of rubber. The anti-slip protective roller sleeve 14 can increase the friction between the feeding roller 4 and the surface of the knurled metal plate, so that the feeding roller 4 will be more stable when it is conveying the knurled metal plate and can protect the surface of the knurled metal plate during the conveying process.

[0026] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
