Description

Technical Field

[0001] The utility model relates to the technical field of jeans processing, in particular to a sandblasting device for jeans. Background Art

[0002] Jeans are a kind of clothing made of cotton cloth, usually featuring wear resistance and durability. The manufacturing process of jeans includes treatment with specific dyes and detergents to obtain their typical color and worn effect. The jeans sandblasting technology uses compressed air as the power to spray brown fused alumina sand onto the jeans, which can roughen and whiten the jeans, and using a template for sandblasting can also produce a cat eyebrow pattern effect. When sandblasting treatment is required for jeans, a special sandblasting device is needed.

[0003] The existing jeans sandblasting treatment is carried out as follows. First, one person puts the jeans on the trouser model, and then hands it over to another person for sandblasting. After sandblasting is completed, it is necessary to hand it over to another person to take off the jeans. In the whole sandblasting process, each step requires different people to complete. Since each person needs time and attention to complete their tasks, the whole process takes a long time. In addition, the cooperation and handover between operators may also lead to waste of time.

[0004] Therefore, it is necessary to design a sandblasting device for jeans. Content of the Utility Model

[0005] In order to overcome the problem of the long time-consuming of the whole process, the utility model provides a sandblasting device for jeans.

[0006] A sandblasting device for jeans includes a frame, a base, an arc-shaped sliding table, sprockets, a shaft rod, a chain, an intermittent motor, mounting arms, connecting frames, cross plates, motors, cylinders, molds, C-shaped frames and spray guns. The frame is the basic carrier, and there are two frames, which are symmetrically distributed left and right. The base is arranged on the inner lower wall of the two frames. The arc-shaped sliding table is arranged between the tops of the two bases. The sprockets are symmetrically rotatably arranged on the arc-shaped sliding table through the shaft rod. A chain is meshed between the two sprockets. The intermittent motor is arranged at the bottom of one of the bases, and the output shaft of the intermittent motor is connected to the shaft rod. The mounting arms are arranged at the left, right, front and rear positions on the top of the chain. The connecting frames are arranged on the side of each mounting arm away from the arc-shaped sliding table. The cross plates are arranged at the lower part of the adjacent connecting frames. The motors are arranged in the middle of the top of the connecting frames. The cylinders are arranged on the output shafts of the adjacent motors. The molds are arranged at the lower ends of the piston rods of the cylinders. The C-shaped frame is arranged in the middle of the arc-shaped sliding table. A spray gun is slidably mounted on the lower part of the C-shaped frame close to the mold side through a cross slide table module.

[0007] Furthermore, it also includes hinge plates, connecting rods and clamping arms. The hinge plates are arranged on the piston rods of the cylinders. The connecting rods are symmetrically hinged at the bottoms of each hinge plate. The clamping arms are hinged at the lower ends of the connecting rods.

[0008] Further, an anti-slip sleeve is sleeved on the lower part of the clamping arm.

[0009] Further, the molds are all located between two adjacent clamping arms.

[0010] Further, the shape of the chain conforms to the shape of the arc-shaped sliding table.

[0011] Further, anti-slip blocks are provided at the bottom of the frame.

[0012] The beneficial effects and remarkable improvements of the present utility model are as follows:

[0013] The present utility model is designed with four molds. Through the intermittent transmission of the intermittent motor, it is ensured that each pair of jeans can be evenly sandblasted. By controlling the cross slide table, the position of the spray gun can be adjusted, so as to achieve comprehensive sandblasting of the jeans.

Specific Embodiments

[0020] The preferred technical solutions of the present utility model will be described in detail below with reference to the drawings.

[0021] Embodiment: A sandblasting device for jeans, please refer to Figures 1 to 5, including a machine frame 1, a base 2, an arc-shaped slide 3, a sprocket 4, a shaft rod 5, a chain 6, an intermittent motor 7, a mounting arm 8, a connecting frame 9, a cross plate 91, a motor 10, a cylinder 11, a hinge plate 12, a connecting rod 13, a clamping arm 14, a mold 15, a C-shaped frame 16 and a spray gun 17. The machine frame 1 is the basic carrier. There are two machine frames 1, and the two machine frames 1 are symmetrically distributed left and right. The middle parts of the two machine frames 1 are hollow-designed. The lower side walls of the inner parts of the two machine frames 1 are both bolted with a base 2. The bottom of the machine frame 1 is provided with anti-slip blocks to increase the friction between the ground and the machine frame 1 and play an anti-slip role. Between the tops of the two bases 2, an arc-shaped slide 3 is fixedly connected by bolts. The middle part of the arc-shaped slide 3 is symmetrically connected with a sprocket 4 by a shaft rod 5 on the left and right. A chain 6 is engaged between the two sprockets 4. The chain 6 is connected to the two sprockets 4. The shape of the chain 6 matches the shape of the arc-shaped slide 3 to ensure that the chain 6 can be smoothly transmitted inside the arc-shaped slide 3. The intermittent motor 7 is installed at the bottom of the left base 2. The output shaft of the intermittent motor 7 rotates through the middle of the base 2 and is connected to the lower end of the left shaft rod 5. The left, right, front and rear parts of the top of the chain 6 are all connected with a mounting arm 8. An arc-shaped groove is opened in the upper part of the arc-shaped slide 3. Each mounting arm 8 is slidably matched with the arc-shaped groove on the arc-shaped slide 3. A connecting frame 9 is installed on the side of each mounting arm 8 away from the arc-shaped slide 3. A cross plate 91 is horizontally connected to the lower part of the connecting frame 9. A motor 10 is installed in the middle of the top of each connecting frame 9. The output shafts of the motors 10 all rotate through the tops of the adjacent connecting frames 9 and are connected with a cylinder 11. The piston rods of the cylinders 11 are all connected with a hinge plate 12, and the piston rods of the cylinders 11 all pass through the middle parts of the adjacent hinge plates 12. The bottom of each hinge plate 12 is symmetrically hinged with a connecting rod 13 on the left and right. The lower ends of the connecting rods 13 are all hinged with a clamping arm 14. The upper parts of the clamping arms 14 are all hinged and connected to the bottom of the adjacent cross plate 91. Anti-slip sleeves are sleeved on the lower parts of the clamping arms 14 to increase the friction between the jeans and the clamping arms 14 and play an anti-slip role. The lower ends of the piston rods of the cylinders 11 are all connected with a mold 15. The molds 15 are all located between the adjacent two clamping arms 14, so that the clamping arms 14 can accurately clamp the jeans. The middle part of the arc-shaped slide 3 is connected with a C-shaped frame 16. A spray gun 17 is slidably installed on the lower part of the C-shaped frame 16 close to the mold 15 through a cross slide module.

[0022] When it is necessary to use a sandblasting device to sandblast jeans, first put the jeans to be processed on four molds 15 respectively. By controlling the piston rod of the cylinder 11 to extend, the articulated plate 12 and the mold 15 are driven to move downward. During this process, the articulated plate 12 will also guide the two connecting rods 13 to perform an articulation action. As the connecting rods 13 are articulated, the two clamping arms 14 will rotate towards each other, thus tightly clamping the jeans. Such a clamping operation enhances the stability of the jeans on the mold 15 and ensures the fixation and accuracy of their positions. After clamping, the operator can connect the spray gun 17 to the designated sandblasting output device, then start the intermittent motor 7 to drive the shaft rod 5 and the sprocket 4 to rotate. Since the two sprockets 4 are engaged with the chain 6, when the two sprockets 4 rotate, they will drive the chain 6 to drive, so that the mounting arm 8, the mold 15 and the jeans on it rotate along the arc-shaped sliding table 3. When the first pair of jeans is transported in front of the spray gun 17, the intermittent motor 7 will pause the driving work, and the spray gun 17 will start sandblasting the jeans. The operator adjusts the position of the spray gun 17 by controlling the cross-slide module to make the spray gun 17 sandblast the jeans comprehensively. When the jeans need to be turned over, just start the motor 10, which will drive the cylinder 11, the mold 15 and the jeans to rotate to complete the turning-over operation. When the first pair of jeans is sandblasted, the intermittent motor 7 will continue to drive the work, and then the next pair of jeans will be sent in front of the spray gun 17, and the spray gun 17 will sandblast the jeans again. By repeating this work, the jeans on the remaining molds 15 can be sandblasted. After all four pairs of jeans are sandblasted, it is necessary to loosen the jeans. By controlling the piston rod of the cylinder 11 to reset, the articulated plate 12 and the mold 15 are driven to move upward. During this process, the articulated plate 12 will guide the two connecting rods 13 to perform a reverse articulation. As the connecting rods 13 are reversely articulated, the two clamping arms 14 will rotate away from each other, thus loosening the jeans. Finally, the operator takes off the processed jeans and puts them into the corresponding collection container.
