Description

Technical Field

[0001] The utility model belongs to the technical field of color-changing boxes, and particularly relates to a double-shaft color-changing box. Background Technique

[0002] A double-shaft color-changing box is a color-changing device with a double-shaft drive function, and is widely used in mechanical equipment such as embroidery and printing that require frequent color changes.

[0003] For example, the Chinese patent with the publication number CN211972677U discloses an adjustable double-shaft drive color-changing box, including a box body, a secondary shaft, a drive shaft and a main gear. A pinhole is fixedly connected to the bottom end of the outer wall of the box body, and a needle position plate is fixedly connected to the top end of the outer wall of the box body. A drive shaft is arranged at the bottom end inside the box body, a main gear is arranged on one side of the drive shaft, a secondary shaft is arranged at the top end inside the box body, a secondary gear is arranged on one side of the secondary shaft, disassembly structures are arranged on both sides of the top end of the box body, protective structures are arranged at the corner positions of the bottom end of the box body, and a tensioning structure is arranged on one side of the box body. By setting the sliding of the tensioning gear driven by the chute and the slider, the belt on the tensioning gear can achieve the tensioning effect, thereby preventing the belt from being too loose and causing the belt to disengage from the gear, resulting in failures and damages.

[0004] The above patent has the following problems:

[0005] When the above patent is in use, there are some disadvantages. For example, when the above device is in use, it is generally fixed to the frame with bolts. After long-term use, the bolts may rust and slip, resulting in difficult disassembly. At the same time, if the lubrication of the gears is insufficient when the above device is in use, it may lead to a decrease in the color-changing speed or inaccurate color-changing, reducing the production efficiency. In view of this, we propose a double-shaft color-changing box. Content of the Utility Model

[0006] The purpose of the utility model is to provide a double-shaft color-changing box to solve the problems raised in the above background technique.

[0007] In view of this, the utility model provides a double-shaft color-changing box, including:

[0008] A double-shaft color-changing box body, a fixed shell is fixedly installed on one side of the double-shaft color-changing box body, a lubrication cavity is opened in the fixed shell, a first gear and a third gear are rotatably installed in the lubrication cavity, one ends of the first gear and the third gear both extend into the double-shaft color-changing box body, and second gears are fixedly installed at the other ends of the first gear and the third gear. A fourth gear is rotatably installed in the lubrication cavity between the two second gears, and the fourth gear meshes with the two second gears;

[0009] A liquid storage cavity is provided, and the liquid storage cavity is opened at the top of the lubrication cavity. A micro water pump is fixedly installed in the lubrication cavity. The water pumping end of the micro water pump is communicated with the lubrication cavity. A sliding frame is inserted and installed in the lubrication cavity, and a filter screen is fixedly installed in the sliding frame. The water outlet end of the micro water pump is communicated with the liquid storage cavity;

[0010] A base is provided, and the base is arranged at the bottom of the double-axis color-changing box body. A limiting cavity is opened in the base. The lower end of the double-axis color-changing box body extends into the limiting cavity, and the lower end of the double-axis color-changing box body is in plug-in fit with the limiting cavity;

[0011] A limiting component is provided, and the limiting component is located in the base and is used to fix the position of the double-axis color-changing box body.

[0012] In this technical solution, when the double-axis color-changing box body is in use, the operator first starts the micro water pump. The micro water pump will transport the lubricating oil in the lubrication cavity to the liquid storage cavity, and then it will fall downward from the liquid storage cavity onto Gear 1, Gear 3, Gear 4, and the two Gears 2, so that they can be evenly lubricated. The lubricated lubricating oil will be filtered by the filter screen and then transported to the liquid storage cavity. The impurities generated during lubrication will be filtered by the filter screen and stay on the top of the filter screen. When it is necessary to remove the impurities on the top of the filter screen, first pull the sliding frame and the filter screen outwards, and finally the operator can remove the impurities on the top of the filter screen. After the impurities are cleaned, the operator inserts the sliding frame into the lubrication cavity again, so that the working efficiency of the double-axis color-changing box body will not be reduced during use;

[0013] The operator first fixes the base to the frame through several bolts. Through the provided limiting component, the operator can place the double-axis color-changing box body on the top of the base. At the same time, the lower end of the double-axis color-changing box body is inserted into the limiting cavity. Through the provided limiting component, the position of the double-axis color-changing box body can be fixed. Through the above operations, the double-axis color-changing box body can be disassembled, which is convenient for the disassembly and installation of the double-axis color-changing box body, and the operation is simple and no tools are required.

[0014] In the above technical solution, further, the limiting component includes:

[0015] Two limiting rods, both of the two limiting rods are slidably installed in the limiting cavity. The sides of the two limiting rods close to each other both extend into the double-axis color-changing box body, and the sides of the two limiting rods close to each other are in plug-in fit with the double-axis color-changing box body. A number of springs fixed to the inner wall of the limiting cavity are fixedly installed on the sides of the two limiting rods away from each other;

[0016] A disc, the disc is rotatably installed in the limiting cavity and is located between the two limiting rods. The circumferential side walls of the disc are in contact with the two limiting rods, and one end of the disc penetrates through the limiting cavity and extends to the outside.

[0017] In this technical solution, first, the operator fixes the base to the frame through several bolts. Then, the operator rotates the operation disk in the positive direction to drive the disk to rotate in the positive direction. The disk will squeeze the two limiting rods to slide away from each other. At the same time, several springs are compressed and contracted. Then, the operator places the biaxial color-changing box body on the top of the base. At the same time, the lower end of the biaxial color-changing box body is inserted into the limiting cavity. Then, the operator rotates the operation disk in the reverse direction. The operation disk drives the disk to rotate in the reverse direction. The disk no longer squeezes the two limiting rods. Under the action of the elastic force of several springs, the two limiting rods slide and approach each other. Then, both of the two limiting rods are inserted into the biaxial color-changing box body, and the position of the biaxial color-changing box body can be fixed. Through the above operations, the biaxial color-changing box body can be disassembled, which is convenient for the disassembly and installation of the biaxial color-changing box body, and the operation is simple without using tools.

[0018] In the above technical solution, further, anti-slip rubber pads are fixedly installed on both sides of the sliding frame.

[0019] In this technical solution, under the action of the anti-slip rubber pads, the position of the sliding frame can be limited, so that the sliding frame will not be displaced.

[0020] In the above technical solution, further, an operation disk is fixedly installed at one end of the disk, and a handle is fixedly installed at one end of the sliding frame.

[0021] In this technical solution, the disk is conveniently rotated through the provided operation disk, and the sliding frame is conveniently pulled through the provided handle.

[0022] In the above technical solution, further, the cross-section of the disk is elliptical.

[0023] In this technical solution, it is ensured that when the disk rotates, it will squeeze the two limiting rods to slide away from each other.

[0024] In the above technical solution, further, the filter screen is located above the water pumping end of the micro water pump, and the top of the filter screen is lower than the top of the sliding frame.

[0025] In this technical solution, it is ensured that the lubricating oil is filtered by the filter screen before being pumped away by the micro water pump, and the impurities in the lubricating oil will stay on the filter screen.

[0026] In the above technical solution, further, the bottom of the lubricating cavity is inclined.

[0027] In this technical solution, it is ensured that the lubricating oil will not remain at the bottom of the lubricating cavity.

[0028] The beneficial effects of the present utility model are:

[0029] 1. For this dual-axis color-changing box, when the dual-axis color-changing box body is in use, the operator first starts the micro water pump. The micro water pump will deliver the lubricating oil in the lubricating cavity to the liquid storage cavity, and then it will fall downward from the liquid storage cavity onto Gear 1, Gear 3, Gear 4, and the two Gears 2, enabling uniform lubrication. The lubricating oil after lubrication will be filtered through the filter screen and then delivered back to the liquid storage cavity. The impurities generated during lubrication will be filtered by the filter screen and stay on the top of the filter screen, which can lubricate Gear 1, Gear 3, Gear 4, and the two Gears 2, and can also filter the impurities generated during lubrication.

[0050] A limiting component is located in the base 12 and is used to fix the position of the dual-axis color-changing box body 1.

[0051] Among them, when the biaxial color-changing box body 1 is in use, the operator first starts the micro water pump 9. The micro water pump 9 will transport the lubricating oil in the lubricating cavity 3 to the liquid storage cavity 7, and then it will fall downward from the liquid storage cavity 7 onto the first gear 4, the third gear 6, the fourth gear 8, and the two second gears 5, so that they can be evenly lubricated. The lubricated lubricating oil will be filtered through the filter screen 11 and then transported back to the liquid storage cavity 7. The impurities generated during lubrication will be filtered by the filter screen 11 and stay on the top of the filter screen 11. When it is necessary to remove the impurities on the top of the filter screen 11, first pull the sliding frame 10 and the filter screen 11 to slide outwards, and finally the operator can remove the impurities on the top of the filter screen 11. After the impurities are cleaned, the operator inserts the sliding frame 10 into the lubricating cavity 3, so that the working efficiency of the biaxial color-changing box body 1 will not be reduced during use;

[0052] The operator first fixes the base 12 to the frame through a number of bolts. Through the provided limiting component, the operator can place the biaxial color-changing box body 1 on the top of the base 12. At the same time, the lower end of the biaxial color-changing box body 1 is inserted into the limiting cavity 13.

Then, the personnel place the biaxial color-changing box body 1 on the top of the base 12, and at the same time, the lower end of the biaxial color-changing box body 1 is inserted into the limiting cavity 13. Then, the personnel rotate the operation disc 18 in the reverse direction. The operation disc 18 drives the disc 16 to rotate in the reverse direction. The disc 16 no longer squeezes the two limiting rods 14. Under the action of the elastic force of several springs 15, the two limiting rods 14 slide and approach each other. Then, both of the two limiting rods 14 are inserted into the biaxial color-changing box body 1, and the position of the biaxial color-changing box body 1 can be fixed. Through the above operations, the biaxial color-changing box body 1 can be disassembled, which is convenient for the disassembly and installation of the biaxial color-changing box body 1, and the operation is simple without the use of tools.

[0071] In this embodiment, the filter screen 11 is located above the water pumping end of the micro water pump 9, and the top of the filter screen 11 is lower than the top of the sliding frame 10.

[0075] In this embodiment, the bottom of the lubricating cavity 3 is inclined.

[0076] Among them, it is ensured that the lubricating oil does not remain at the bottom of the lubricating cavity 3.

[0077] Working principle: When the dual-axis color-changing box body 1 is in use, the operator first starts the micro water pump 9. The micro water pump 9 will transport the lubricating oil in the lubricating cavity 3 to the liquid storage cavity 7, and then it will fall downward from the liquid storage cavity 7 onto the first gear 4, the third gear 6, the fourth gear 8, and the two second gears 5, so that they can be evenly lubricated. The lubricated lubricating oil will be filtered by the filter screen 11 and then transported to the liquid storage cavity 7. The impurities generated during lubrication will be filtered by the filter screen 11 and stay on the top of the filter screen 11. When it is necessary to remove the impurities on the top of the filter screen 11, first pull the handle 17 and drive the sliding frame 10 and the filter screen 11 to slide outwards. Finally, the operator can remove the impurities on the top of the filter screen 11. After the impurities are cleaned, the operator inserts the sliding frame 10 into the lubricating cavity 3 again. Under the action of the anti-slip rubber pad, the position of the sliding frame 10 can be limited, so that the sliding frame 10 will not be displaced, and the working efficiency of the dual-axis color-changing box body 1 will not be reduced during use;

[0078] First, the operator fixes the base 12 to the frame through several bolts. Then, the operator rotates the operation disk 18 in the forward direction to drive the disk 16 to rotate forward. The disk 16 will squeeze the two limiting rods 14 to slide and move away from each other. At the same time, several springs 15 are squeezed and contracted. Then, the operator places the biaxial color-changing box body 1 on the top of the base 12. At the same time, the lower end of the biaxial color-changing box body 1 is inserted into the limiting cavity 13. Then, the operator rotates the operation disk 18 in the reverse direction. The operation disk 18 drives the disk 16 to rotate in the reverse direction. The disk 16 no longer squeezes the two limiting rods 14. Under the action of the rebounding force of several springs 15, the two limiting rods 14 slide and move closer to each other. Then, both of the two limiting rods 14 are inserted into the biaxial color-changing box body 1, and the position of the biaxial color-changing box body 1 can be fixed. Through the above operations, the biaxial color-changing box body 1 can be disassembled, which is convenient for the disassembly and installation of the biaxial color-changing box body 1, and the operation is simple without using tools.
