Description

Technical Field

[0001] This utility model relates to the field of clothing processing equipment technology, specifically to a cylindrical assembly and clothing processing equipment. Background Technology

[0002] In three-drum washing machines of related technologies, to meet users' needs for separate washing of clothes, they are typically equipped with one large drum and two small drums, used for washing socks, underwear, and items of different sizes respectively. This effectively prevents cross-contamination of bacteria and improves washing performance and hygiene. To maintain the overall balance of the three-drum washing machine and reduce vibration and noise during operation, counterweights are placed on both the large and small drums. However, three-drum washing machines of related technologies are prone to vibration and noise during operation, reducing the user experience. Utility Model Content

[0003] This utility model aims to at least partially solve one of the technical problems in the related art.

[0004] Therefore, embodiments of this utility model propose a tube assembly and a garment processing device.

[0005] The cylindrical assembly of this utility model embodiment includes a first processing cylinder, a second processing cylinder, a third processing cylinder, and a first counterweight. The second processing cylinder and the third processing cylinder are disposed above the first processing cylinder and spaced apart in the left-right direction. The first counterweight is disposed between the second processing cylinder and the third processing cylinder, and the lowest point of the first counterweight is higher than the point of the second processing cylinder closest to the first processing cylinder and the point of the third processing cylinder closest to the first processing cylinder.

[0006] The center of gravity of the first counterweight, second processing cylinder, and third processing cylinder is positioned higher, echoing the center of gravity of the first processing cylinder in the vertical direction. This optimizes the weight distribution of the entire cylinder assembly in the vertical direction. This results in a more rational weight distribution throughout the cylinder assembly, reducing vibrations caused by uneven weight distribution and maintaining the overall balance of the cylinder assembly. Consequently, it reduces vibration and noise during operation, improving user experience and durability.

[0007] Furthermore, since the lowest point of the first counterweight is higher than the point where the second processing cylinder is closest to the first processing cylinder and the point where the third processing cylinder is closest to the first processing cylinder, the space below the first counterweight, the second processing cylinder and the third processing cylinder can be used to fit the outer periphery of the first processing cylinder, making the components of the cylinder assembly more compact in the vertical direction, optimizing the spatial arrangement and saving space.

[0008] Optionally, the arc-shaped curves of the point closest to the first processing drum of the second processing drum, the lowest point of the first counterweight, and the point closest to the first processing drum of the third processing drum protrude upwards in a direction away from the first processing drum. This further shifts the overall center of gravity of the first counterweight, the second processing drum, and the third processing drum higher, helping to further optimize the weight distribution of the entire drum assembly in the vertical direction, making the center of gravity of the washing machine more stable during operation.

[0009] In addition, the arc-shaped curves of the second processing cylinder closest to the first processing cylinder, the lowest point of the first counterweight, and the third processing cylinder closest to the first processing cylinder protrude upwards in the direction away from the first processing cylinder. This makes the space below the first counterweight, the second processing cylinder, and the third processing cylinder more compatible with the outer periphery of the first processing cylinder, making the components of the cylinder assembly more compact in the vertical direction, further optimizing the spatial layout, and further saving space.

[0010] Optionally, the arc curve is a circular arc curve, and the center of the circular arc curve coincides with the central axis of the first processing cylinder. This enhances the symmetry of the entire cylinder assembly, helps to balance the overall structure, prevents the cylinder assembly from moving or shaking due to imbalance during operation, effectively reduces the vibration generated by the cylinder assembly during high-speed rotation, and further reduces noise.

[0011] Optionally, the width of the first counterweight in the left-right direction first decreases and then increases from top to bottom. By first decreasing and then increasing the width of the first counterweight in the left-right direction from top to bottom, the first counterweight can fit into the irregular space between the second and third processing cylinders. This not only facilitates the installation of the first counterweight but also maximizes the utilization of the irregular space between the second and third processing cylinders, reducing the gap between the first counterweight and the second and third processing cylinders, and further improving space utilization.

[0012] Optionally, the width of the first counterweight increases from top to bottom in the left-right direction.

[0013] In other words, the top width of the first counterweight is smaller than its bottom width. When installing the first counterweight, it can be moved upwards and positioned in the space between the second and third processing cylinders to accommodate the irregular space between them. This not only facilitates the installation of the first counterweight but also maximizes the utilization of the irregular space between the second and third processing cylinders, reducing the gap between them and further improving space utilization.

[0014] Optionally, the width of the first counterweight in the left-right direction decreases from top to bottom.

[0015] In other words, the top width of the first counterweight is smaller than its bottom width. When installing the first counterweight, it can be moved upwards and positioned in the space between the second and third processing cylinders to accommodate the irregular space between them. This not only facilitates the installation of the first counterweight but also maximizes the utilization of the irregular space between the second and third processing cylinders, reducing the gap between them and further improving space utilization.

[0016] Optionally, the bottom surface of the first counterweight is an upwardly concave first arc-shaped surface, and the top surface of the first counterweight is a downwardly concave second arc-shaped surface. The arrangement of the upper and lower arc-shaped surfaces helps to reduce stress concentration and avoid excessive stress at a single point, so that the first counterweight can better distribute and bear the forces from the operation of the second and third processing cylinders, thereby reducing the risk of damage to the first counterweight and increasing its impact resistance and durability.

[0017] Optionally, a first side of the first counterweight faces the outer periphery of the second processing cylinder or a portion of the outer periphery of the second processing cylinder door seal, and a second side of the first counterweight faces the outer periphery of the third processing cylinder or a portion of the outer periphery of the third processing cylinder door seal. The shape of the first side matches the shape of the portion of the outer periphery of the second processing cylinder or the second processing cylinder door seal, and the shape of the second side matches the shape of the portion of the outer periphery of the third processing cylinder or the third processing cylinder door seal.

[0018] The first counterweight is positioned closer to the outer periphery of the second processing cylinder or the outer periphery of the second processing cylinder door seal, reducing the distance between the first counterweight and the second processing cylinder. This maximizes the use of the limited space between the second and third processing cylinders, thereby optimizing the internal spatial layout of the cylinder assembly and further improving space utilization.

[0019] The first counterweight is positioned closer to the outer periphery of the third processing cylinder or the outer periphery of the third processing cylinder door seal, reducing the distance between the first counterweight and the third processing cylinder and maximizing the use of the limited space between the second and third processing cylinders. This optimizes the internal spatial layout of the cylinder assembly and further improves space utilization.

[0020] Optionally, the second processing cylinder and the third processing cylinder are symmetrical about a vertical plane passing through the axis of the first processing cylinder.

[0021] A symmetrical design ensures even weight distribution in the left-right direction for the second and third drums, improving the overall balance of the drum assembly and reducing vibration and noise during operation. Furthermore, a symmetrical design reduces production costs by minimizing manufacturing complexity and allowing the same parts or molds to be used to produce both drums. The structural symmetry also makes maintenance and parts replacement more efficient, enabling repair personnel to quickly locate and resolve problems. A symmetrical layout contributes to increased structural strength of the entire washing machine, as symmetrical structures are generally more stable.

[0022] Optionally, the center of the opening of the second processing cylinder and the center of the opening of the third processing cylinder are located in the same horizontal plane, and the central axis of the second processing cylinder and the central axis of the third processing cylinder are located on both sides of the central axis of the first processing cylinder in the left-right direction.

[0023] Because the centers of the openings of the second and third processing drums are on the same horizontal plane, users can more easily operate both drums simultaneously to load and unload clothes. The central axes of the second and third processing drums are located on either side of the central axis of the first processing drum. This symmetrical axial layout helps maintain the balance of the overall structure, reduces offset and vibration during operation, and improves the stability of the washing machine, especially when it is fully loaded.

[0024] Optionally, the openings of each of the first processing cylinder, the second processing cylinder, and the third processing cylinder are arranged facing forward.

[0025] A forward-facing drum opening makes loading and unloading clothes more convenient for users, as they can directly face the drum opening without having to go around to the back or side of the washing machine. The forward-facing drum opening is better suited to home environments, especially in spaces with limited space, as users can more easily access and control each drum. The forward-facing drum opening design reduces the risk of accidental contact with internal rotating parts during operation, improving safety. Furthermore, the forward-facing drum opening design allows the washing machine to flexibly adapt to different installation environments, whether built-in or freestanding.

[0026] Optionally, the cylinder assembly further includes a second counterweight and a third counterweight, the second counterweight being installed on the left side of the second processing cylinder and adjacent to the front side of the second processing cylinder, the third counterweight being installed on the right side of the third processing cylinder and adjacent to the front side of the third processing cylinder, and the first counterweight being adjacent to the front sides of the second processing cylinder and the third processing cylinder.

[0027] The second and third counterweights are installed on both sides of the second and third processing cylinders, respectively, which helps to further balance the weight distribution of the entire cylinder assembly in the left and right directions, optimize the balance of the cylinder assembly in the left and right directions, and enhance the overall stability of the cylinder assembly.

[0028] Since the drive motors of the second and third processing cylinders are both located at the rear, and the first, second, and third counterweights are all located near the front of the second and third processing cylinders, the weight distribution of the cylinder assembly in the front-rear direction can be better distributed, so that the weight of the cylinder assembly is also balanced in the front-rear direction, reducing the vibration and noise of the cylinder assembly during operation.

[0029] Optionally, the second counterweight has a third side and a fourth side opposite to each other in the left-right direction. The third side is disposed adjacent to the second processing cylinder. The shape of the third side matches the outer peripheral contour of the second processing cylinder or a part of the outer peripheral contour of the second processing cylinder door seal. The fourth side is a vertical surface.

[0030] The third counterweight has a fifth side and a sixth side opposite to each other in the left-right direction. The fifth side is disposed adjacent to the third processing cylinder. The shape of the fifth side matches the outer periphery of the third processing cylinder or a part of the outer periphery of the third processing cylinder door seal. The sixth side is a vertical surface.

[0031] The shape of the third side matches the outer periphery of the second processing cylinder or a part of the outer periphery of the second processing cylinder door seal, so that the second counterweight is set closer to the outer periphery of the second processing cylinder or the outer periphery of the second processing cylinder door seal, reducing the distance between the second counterweight and the second processing cylinder, making the most of the limited space on one side of the second processing cylinder to install the second counterweight, which can make more effective use of the internal space, reduce unnecessary gaps, and further improve the space utilization rate.

[0032] The shape of the fifth side matches the outer periphery of the third processing cylinder or part of the outer periphery of the third processing cylinder door seal, so that the third counterweight is set closer to the outer periphery of the third processing cylinder or the outer periphery of the third processing cylinder door seal, reducing the distance between the third counterweight and the third processing cylinder, making the most of the limited space on one side of the third processing cylinder to install the third counterweight, making more effective use of the internal space, reducing unnecessary gaps, and further improving space utilization.

[0033] Optionally, the front wall of the second counterweight has a first groove extending in the left-right direction, the first groove being used to install at least a portion of the cylinder cover hinge of the second processing cylinder, and the front wall of the third counterweight has a second groove extending in the left-right direction, the second groove being used to install at least a portion of the cylinder cover hinge of the third processing cylinder.

[0034] The first groove provides a fixed mounting position for at least a portion of the hinge of the second processing cylinder's cover, enhancing the connection stability between the cover and the second counterweight, thereby improving the structural strength of the entire cylinder assembly. The second groove provides a fixed mounting position for at least a portion of the hinge of the third processing cylinder's cover, further enhancing the connection stability between the cover and the third counterweight, thus improving the structural strength of the entire cylinder assembly. Furthermore, the specialized groove design simplifies and simplifies the cover installation process, reducing installation errors and improving production efficiency.

[0035] Optionally, the lowest point of the second counterweight is located above the lowest point of the second processing cylinder, and the highest point of the second counterweight is located below the highest point of the second processing cylinder.

[0036] The lowest point of the third counterweight is located above the lowest point of the third processing cylinder, and the highest point of the third counterweight is located below the highest point of the third processing cylinder.

[0037] The lowest point of the second counterweight is located above the lowest point of the second drum, and the highest point of the second counterweight is located below the highest point of the second drum. This arrangement of the second counterweight can better adapt to different washing loads, maintain the balance of the drum assembly when washing clothes of different weights, help maintain the stability of the entire washing machine structure, and prevent tilting during operation.

[0038] The lowest point of the third counterweight is located above the lowest point of the second drum, and the highest point of the third counterweight is located below the highest point of the third drum. This arrangement of the third counterweight can better adapt to different washing loads, maintain the balance of the drum assembly when washing clothes of different weights, help maintain the stability of the entire washing machine structure, and prevent tilting during operation.

[0039] The garment processing device of this utility model embodiment includes a housing and a cylindrical assembly, wherein the cylindrical assembly is installed inside the housing, and the cylindrical assembly is the cylindrical assembly described in any of the above embodiments.

[0040] The weight distribution of the entire cylinder assembly of the garment processing device in this embodiment is more reasonable in the vertical direction, reducing vibration caused by uneven weight distribution, thus maintaining the balance of the entire garment processing device, thereby reducing vibration and noise during operation, and improving user experience and durability.

[0051] The embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0052] In related technologies, due to the limited internal space and numerous internal components of three-drum washing machines, there are difficulties in arranging counterweights on the two small drums, resulting in uneven weight distribution in the three-drum washing machine. This can easily cause vibration and noise during operation, reducing the user experience.

[0053] like Figures 1 to 8 As shown, the cylindrical assembly 100 of this utility model embodiment includes a first processing cylinder 1, a second processing cylinder 2, a third processing cylinder 3, and a first counterweight 4. The second processing cylinder 2 and the third processing cylinder 3 are located above the first processing cylinder 1 and spaced apart in the left-right direction. The first counterweight 4 is located between the second processing cylinder 2 and the third processing cylinder 3. The lowest point of the first counterweight 4 is higher than the point on the second processing cylinder 2 closest to the first processing cylinder 1 and the point on the third processing cylinder 3 closest to the first processing cylinder 1.

[0054] The cylinder assembly 100 of this utility model sets the first counterweight 4 between the second processing cylinder 2 and the third processing cylinder 3, effectively utilizing the space between the second processing cylinder 2 and the third processing cylinder 3, reducing space waste, and improving the overall space utilization rate.

[0055] Because the lowest point of the first counterweight 4 is higher than the closest point of the second processing cylinder 2 to the first processing cylinder 1 and the closest point of the third processing cylinder 3 to the first processing cylinder 1, the overall center of gravity of the first counterweight 4, the second processing cylinder 2, and the third processing cylinder 3 is positioned higher, corresponding to the center of gravity of the first processing cylinder 1 in the vertical direction, thus optimizing the weight distribution of the entire cylinder assembly 100 in the vertical direction. This makes the weight distribution of the entire cylinder assembly 100 more reasonable in the vertical direction, reducing vibration caused by uneven weight distribution, maintaining the balance of the entire cylinder assembly 100, thereby reducing vibration and noise during operation, improving user experience and durability.

[0056] Furthermore, since the lowest point of the first counterweight 4 is higher than the point of the second processing cylinder 2 closest to the first processing cylinder 1 and the point of the third processing cylinder 3 closest to the first processing cylinder 1, the space below the first counterweight 4, the second processing cylinder 2 and the third processing cylinder 3 can be used to fit the outer periphery of the first processing cylinder 1, making the components of the cylinder assembly 100 more compact in the vertical direction, optimizing the spatial arrangement, and saving space.

[0057] It should be noted that each of the first treatment drum 1, the second treatment drum 2, and the third treatment drum 3 includes an outer drum and an inner drum. For example, if used for washing clothes, the outer drum is the water-holding drum, and the inner drum is called the washing drum.

[0058] In some embodiments, the arc curve 5 of the second processing cylinder 2 closest to the first processing cylinder 1, the lowest point of the first counterweight 4, and the third processing cylinder 3 closest to the first processing cylinder 1 protrudes upward in a direction away from the first processing cylinder 1.

[0059] like Figure 3As shown, the arc curve 5 protrudes upward, which means that the center of gravity of the first counterweight 4 is set higher. This makes the overall center of gravity of the first counterweight 4, the second processing drum 2, and the third processing drum 3 set higher, which helps to further optimize the weight distribution of the entire drum assembly 100 in the vertical direction and makes the center of gravity of the washing machine more stable during operation.

[0060] In addition, the arc curve 5 of the second processing cylinder 2 closest to the first processing cylinder 1, the lowest point of the first counterweight 4, and the third processing cylinder 3 closest to the first processing cylinder 1 protrudes upward in the direction away from the first processing cylinder 1, so that the space below the first counterweight 4, the second processing cylinder 2, and the third processing cylinder 3 is more adapted to the outer periphery of the first processing cylinder 1, and the components of the cylinder assembly 100 are arranged more compactly in the vertical direction, further optimizing the spatial layout and further saving space.

[0061] Optionally, the arc curve 5 is a circular arc curve, and the center of the circular arc curve coincides with the central axis of the first processing cylinder 1.

[0062] It should be noted that "arc curve" is a broader concept, referring to any curved shape, not necessarily limited to a circle. An arc curve can be a circular arc, or other types of curves, such as an elliptical arc, a portion of a parabola, or any smooth curved shape. The curvature of an arc curve can vary at different points and does not necessarily have a fixed center.

[0063] A circular arc is a portion of a curve between any two points on a circle. Its definition strictly depends on the circle itself; that is, an arc is a part of a circle, has a fixed center, and every point on the circle is equidistant from the center (i.e., its radius). The central angle of an arc is less than or equal to 360 degrees.

[0064] The center of the arc curve coincides with the central axis of the first processing cylinder 1, which enhances the symmetry of the entire cylinder assembly 100, helps to balance the overall structure, prevents the cylinder assembly 100 from moving or shaking due to imbalance during operation, effectively reduces the vibration generated by the cylinder assembly 100 when rotating at high speed, and further reduces noise.

[0065] In some embodiments, the width of the first counterweight 4 in the left-right direction first decreases and then increases from top to bottom.

[0066] like Figure 4 , Figure 5 and Figure 8As shown, since the outer contours of the second processing cylinder 2 and the third processing cylinder 3 are both circular, the space between the second processing cylinder 2 and the third processing cylinder 3 is an irregular space, and the dimension of this irregular space in the left-right direction first decreases and then increases from top to bottom. Therefore, by making the width dimension of the first counterweight 4 in the left-right direction first decrease and then increase from top to bottom, the first counterweight 4 can fit into the irregular space between the second processing cylinder 2 and the third processing cylinder 3. This not only facilitates the installation of the first counterweight 4, but also maximizes the utilization of the irregular space between the second processing cylinder 2 and the third processing cylinder 3, reduces the gap between the first counterweight 4 and the second processing cylinder 2 and the third processing cylinder 3, and further improves the space utilization rate.

[0067] In other embodiments, such as Figure 7 As shown, the width of the first counterweight 4 in the left-right direction increases from top to bottom.

[0068] In other words, the top width of the first counterweight 4 is smaller than its bottom width. When installing the first counterweight 4, it can be moved from bottom to top and placed in the space between the second processing cylinder 2 and the third processing cylinder 3 to accommodate the irregular space between them. This not only facilitates the installation of the first counterweight 4 but also maximizes the utilization of the irregular space between the second processing cylinder 2 and the third processing cylinder 3, reducing the gap between them and further improving space utilization.

[0069] In other embodiments, such as Figure 6 As shown, the width of the first counterweight 4 in the left-right direction decreases from top to bottom.

[0070] In other words, the top width of the first counterweight 4 is greater than its bottom width. When installing the first counterweight 4, it can be moved from top to bottom and placed in the space between the second processing cylinder 2 and the third processing cylinder 3 to accommodate the irregular space between them. This not only facilitates the installation of the first counterweight 4 but also maximizes the utilization of the irregular space between the second processing cylinder 2 and the third processing cylinder 3, reducing the gap between them and further improving space utilization.

[0071] In some embodiments, the bottom surface of the first counterweight 4 is an upwardly concave first arc-shaped surface 401, and the top surface of the first counterweight 4 is a downwardly concave second arc-shaped surface 402.

[0072] like Figure 5As shown, the upper and lower arc surfaces help reduce stress concentration and avoid excessive stress at a single point, so that the first counterweight 4 can better distribute and bear the force from the second processing cylinder 2 and the third processing cylinder 3 during operation, thereby reducing the risk of damage to the first counterweight 4 and increasing the impact resistance and durability of the first counterweight 4.

[0073] In some embodiments, the first side 403 of the first counterweight 4 faces the outer periphery of the second processing cylinder 2 or a portion of the outer periphery of the second processing cylinder 2 door seal, and the second side 404 of the first counterweight 4 faces the outer periphery of the third processing cylinder 3 or a portion of the outer periphery of the third processing cylinder 3 door seal. The shape of the first side 403 matches the shape of the outer periphery of the second processing cylinder 2 or a portion of the outer periphery of the second processing cylinder 2 door seal, and the shape of the second side 404 matches the shape of the outer periphery of the third processing cylinder 3 or a portion of the outer periphery of the third processing cylinder 3 door seal.

[0074] like Figures 2 to 4 As shown, the shape of the first side 403 matches the shape of the outer periphery of the second processing cylinder 2 or a part of the outer periphery of the door seal of the second processing cylinder 2, so that the first counterweight 4 is set closer to the outer periphery of the second processing cylinder 2 or the outer periphery of the door seal of the second processing cylinder 2, reducing the distance between the first counterweight 4 and the second processing cylinder 2, making the most of the limited space between the second processing cylinder 2 and the third processing cylinder 3, thereby optimizing the internal spatial layout of the cylinder assembly 100 and further improving the space utilization rate.

[0075] Similarly, the shape of the second side 404 matches the shape of the outer periphery of the third processing cylinder 3 or a part of the outer periphery of the door seal of the second processing cylinder 2, so that the first counterweight 4 is set closer to the outer periphery of the second processing cylinder 2 or the outer periphery of the door seal of the third processing cylinder 3, reducing the distance between the first counterweight 4 and the third processing cylinder 3, making the most of the limited space between the second processing cylinder 2 and the third processing cylinder 3, thereby optimizing the internal spatial layout of the cylinder assembly 100 and further improving the space utilization rate.

[0076] In some embodiments, the second processing cylinder 2 and the third processing cylinder 3 are symmetrical about a vertical plane passing through the axis of the first processing cylinder 1.

[0077] The symmetrical design ensures a uniform weight distribution in the left-right direction for the second and third processing drums 2 and 3, thereby improving the overall balance of the drum assembly 100 and reducing vibration and noise during operation. Furthermore, the symmetrical design reduces production costs because it decreases manufacturing complexity and allows for the production of both the second and third processing drums 2 and 3 using the same components or molds. Due to the structural symmetry, maintenance and component replacement are more efficient, allowing maintenance personnel to quickly locate and resolve problems. The symmetrical layout also contributes to improved structural strength of the entire washing machine, as symmetrical structures are generally more stable.

[0078] Optionally, the center of the opening of the second processing cylinder 2 and the center of the opening of the third processing cylinder 3 are located in the same horizontal plane, and the central axis of the second processing cylinder 2 and the central axis of the third processing cylinder 3 are located on both sides of the central axis of the first processing cylinder 1 in the left-right direction.

[0079] like Figure 1 and Figure 2 As shown, since the centers of the openings of the second processing drum 2 and the third processing drum 3 are on the same horizontal plane, users can more easily operate both drums simultaneously to load and unload clothes. The central axes of the second processing drum 2 and the third processing drum 3 are located on both sides of the central axis of the first processing drum 1. This symmetrical axial layout helps maintain the balance of the overall structure, reduces offset and vibration during operation, and helps improve the stability of the washing machine, especially when the washing machine is fully loaded.

[0080] In some embodiments, the openings of each of the first processing cylinder 1, the second processing cylinder 2, and the third processing cylinder 3 are arranged facing forward.

[0081] like Figure 1 and Figure 2 As shown, a forward-facing drum opening makes loading and unloading clothes more convenient for users, as they can directly face the drum opening without having to go around to the back or side of the washing machine. A forward-facing drum opening is better suited to home environments, especially in spaces with limited space, as users can more easily access and control each drum. The forward-facing drum opening design reduces the risk of accidental contact with internal rotating parts during operation, improving safety. Furthermore, the forward-facing drum opening design allows the washing machine to flexibly adapt to different installation environments, whether built-in or freestanding.

[0082] In some embodiments, the cylinder assembly 100 further includes a second counterweight 6 and a third counterweight 7. The second counterweight 6 is installed on the left side of the second processing cylinder 2 and adjacent to the front side of the second processing cylinder 2, the third counterweight 7 is installed on the right side of the third processing cylinder 3 and adjacent to the front side of the third processing cylinder 3, and the first counterweight 4 is adjacent to the front sides of the second processing cylinder 2 and the third processing cylinder 3.

[0083] like Figure 2 and Figure 3 As shown, the second counterweight 6 and the third counterweight 7 are respectively installed on both sides of the second processing cylinder 2 and the third processing cylinder 3, which helps to further balance the weight distribution of the entire cylinder assembly 100 in the left and right directions, optimize the balance of the cylinder assembly 100 in the left and right directions, and enhance the overall stability of the cylinder assembly 100.

[0084] Since the drive motors of the second processing cylinder 2 and the third processing cylinder 3 are both located at the rear, and the first counterweight 4, the second counterweight 6 and the third counterweight 7 are all located near the front of the second processing cylinder 2 and the third processing cylinder 3, the weight distribution of the cylinder assembly 100 in the front-rear direction can be better distributed, so that the weight of the cylinder assembly 100 is also balanced in the front-rear direction, reducing the vibration and noise of the cylinder assembly 100 during operation.

[0085] In some embodiments, the second counterweight 6 has a third side 601 and a fourth side 602 that are opposite each other in the left-right direction. The third side 601 is disposed adjacent to the second processing cylinder 2. The shape of the third side 601 matches the outer peripheral contour of the second processing cylinder 2 or a part of the outer peripheral contour of the door seal of the second processing cylinder 2.
