Description

Technical Field

[0001] This invention relates to the field of vending machine technology, specifically to the outer shell structure of an ultra-high-speed computer embroidery machine head. Background Technology

[0002] The working principle of an ultra-high-speed computerized embroidery machine head is to precisely control the coordinated movement of various drive mechanisms through a computer control system, thereby achieving high-speed and precise embroidery. Specifically, when the computer issues an embroidery command, the main shaft begins to rotate and transmits power to the input drive shaft through a clutch mechanism. The input drive shaft then transmits power to the needle bar drive mechanism, presser foot drive mechanism, and thread take-up drive mechanism. Under the action of power, these drive mechanisms drive the needle bar, presser foot, and thread take-up lever to move along a predetermined trajectory and speed. Driven by the needle bar, the embroidery needle quickly pierces the fabric up and down. At the same time, the presser foot presses the fabric tightly, and the thread take-up lever delivers and tightens the top thread in a timely manner, thus forming a beautiful embroidery pattern on the fabric. The machine casing is the external frame of the machine head, which supports and protects the internal components. It is usually made of high-strength aluminum alloy and other materials, which can effectively reduce weight while ensuring the strength of the machine body, thus facilitating the high-speed operation of the machine head.

[0003] The existing high-speed computerized embroidery machine head has a complex internal structure. During milling, drilling, and other machining operations, the internal structure hinders the cutting tools from following the preset path, leading to insufficient precision and stress concentration. Furthermore, the internal structure restricts the installation of side accessories on the machine head. Insufficient precision in the internal cavity directly affects the installation accuracy of the guide rails. This inaccuracy affects the positioning accuracy of the guide rails within the internal cavity. If the guide rails deviate from their position, the machine housing will not be able to provide sufficient support, causing deformation of the guide rails after long-term use, thus affecting the embroidery accuracy. Summary of the Invention

[0004] The purpose of this invention is to provide a housing structure for the head of an ultra-high-speed computerized embroidery machine, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a shell structure for a high-speed computerized embroidery machine head, comprising a shell body; a shell cavity is provided inside the shell body, a connecting plate is provided inside the shell cavity, a convex suspension is provided on the connecting plate, a side plate is provided on one side of the shell body, a back plate is connected to the left end of the connecting plate and the side plate, a support assembly is connected to the upper end of the side plate and the back plate, the support assembly is used to connect a guide rail, the support assembly includes a connecting platform, an oiling assembly is provided on the upper surface of the connecting platform, the oiling assembly is used to oil the guide rail.

[0006] Through the above technical solution, the connecting plate, side plate, back plate, and connecting platform are interconnected to form the housing cavity. The housing cavity is formed using a core-pulling process. This process allows for the easy formation of recesses, protrusions, through holes, and various irregular structures within the housing cavity, facilitating the accommodation and protection of precision transmission components or complex wiring structures. Furthermore, during the mold opening process, a series of protective measures are implemented for the key support and rotation points on the mold. Protecting these support points extends the mold's lifespan and ensures the accuracy and stability of the mold's opening and closing actions during housing production, thereby guaranteeing the housing's molding quality. The convex suspension structure of the convex suspension system ensures the overall integrity of the housing... While enhancing structural strength, this one-piece molding design also increases the possibility of additional space utilization. This makes it easier to process the casing in a machining center, reducing the difficulty and complexity of processing. Furthermore, through a reasonable structural design, the stress in all parts of the internal cavity can be evenly distributed, avoiding stress concentration. This helps prevent local deformation or damage to the casing during long-term use, improving the reliability and durability of the casing. Moreover, this molding design fully considers the installation and use of side-mounted accessories. The structure of the casing will not hinder the installation of these accessories, and the accessories will not be affected by deformation or vibration during operation.

[0007] Furthermore, the overall housing cavity has a trapezoidal structure, and the top of the housing cavity has a slightly arched design.

[0008] Through the above technical solution, the micro-arched design at the top of the housing cavity can provide sufficient space to accommodate taller components such as motors. The depth and diameter of the internal recess are precisely designed according to the size of the sensor. The interior of the housing cavity can be divided into a power area, a transmission area, and a control area. The power area is located on one side of the housing cavity and has a large space for placing power sources such as motors. It is also connected to a dedicated heat dissipation channel. The transmission area is next to the power area and contains various transmission components such as gears and pulleys. Its spatial design takes into account the movement trajectory and mutual cooperation of the transmission components. The control area is relatively enclosed and is used to install control components such as circuit boards to avoid external interference.

[0009] Furthermore, the convex suspension is located inside the main body of the housing, and its front cross-section shows a circular structure.

[0010] Through the above technical solution, the protruding suspension located inside the main body of the casing protrudes outward, which can create additional space inside the main body of the casing. This space can be used to install some control components that do not have high space requirements but are in a critical position, making the use of space inside the casing more efficient. Moreover, this inner protruding suspension structure fully considers the overall strength and stability of the casing during the design. Its shape, size and connection method have been carefully designed so that while increasing space utilization, it will not interfere with other parts of the casing, nor will it weaken the overall structural strength of the casing.

[0011] Furthermore, the lower edge of the connecting platform is equipped with reinforcing ribs, and the edge of the connecting platform has an arc-shaped structure.

[0012] The above technical solution involves designing cantilevered reinforcing ribs along the lower edge of the guide rail as a measure to enhance structural stability. The cantilevered reinforcing ribs are similar to a cantilever beam structure, extending outward from the lower edge of the guide rail and reinforcing it. This structure can effectively increase the bending and torsional strength of the guide rail. When the ball bearing guide rail pair is subjected to various forces during operation, the cantilevered reinforcing ribs can share these forces and prevent the guide rail from undergoing excessive deformation.

[0013] Furthermore, the length of the reinforcing rib is greater than the width of the housing cavity, and the reinforcing rib has a straight strip structure.

[0014] Through the above technical solution, when the length of the reinforcing rib is greater than the width of the housing cavity, the longer reinforcing rib can transmit and disperse these forces along its length, reducing the possibility of local deformation of the housing and providing support and reinforcement over a larger area. The straight reinforcing rib is not only simple in structure and relatively easy to form and process, but also easier to realize in the manufacturing process, which helps to reduce the difficulty and cost of manufacturing. Furthermore, the presence of the straight reinforcing rib will not cause too much obstruction to the installation and maintenance of other components inside the housing. Due to its regular shape, other components can be more easily installed inside the housing cavity without avoiding the reinforcing rib. Moreover, when it is necessary to maintain or replace the components, the straight reinforcing rib will not hinder the operation like some complex-shaped reinforcing structures.

[0015] Furthermore, the right side of the connecting platform and the right side of the connecting plate are located on the same vertical plane.

[0016] Through the above technical solution, the right side of the connecting platform and the right side of the connecting plate are very flat and parallel, which can ensure that the guide rail can be accurately installed and the machine head can move in a straight line. The groove space inside the housing cavity not only provides the installation position, but its flat inner wall and precise dimensions also ensure that the guide rail pair can run smoothly, thus providing precise guidance for the linear movement of the embroidery needle drive mechanism. Within the range of motion of the moving parts, the inside of the housing cavity also reserves enough space to avoid collision between the moving parts and the inner wall of the housing cavity.

[0017] Furthermore, the oil injection assembly includes an oil injection groove and an oil injection hole, which are interconnected.

[0018] Through the above technical solution, the shape, size and position of the oil injection groove and oil injection hole are carefully designed to ensure that the lubricating oil can flow fully in the required parts, so that the lubricating oil can accurately reach the friction surface and play a good lubricating role. After completing the lubrication task, the lubricating oil can be smoothly discharged according to the preset path. This process avoids the accumulation and chaotic flow of lubricating oil inside the housing, which helps to prevent the lubricating oil from contaminating other parts or affecting the normal operation of the equipment.

[0019] Furthermore, the opening of the oil injection groove is flush with the side plate, the oil injection groove has an "L" shaped structure, and the oil injection hole has a circular structure.

[0020] With the above technical solution, when the opening of the oil injection groove is flush with the side plate, it is easier to process during manufacturing, thereby reducing processing errors. Moreover, because its opening position is clear and flat, it is conducive to the accurate positioning and sealing installation of connecting parts. The "L"-shaped oil injection groove can provide lubrication for multiple parts in different directions or positions at the same time, reducing the complexity and cost of setting up an oil injection device for each part individually. The design of the circular oil injection hole can make the stress evenly distributed around the hole, making it less likely to cause stress concentration, thereby reducing the risk of fatigue, cracking and other damage to the material around the oil injection hole, and ensuring the structural integrity and service life of the oil injection hole.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] Firstly, in this invention, the housing cavity is a hollow portion formed by the interconnection of connecting plates, side plates, back plates, and connecting platforms. The housing cavity is formed using a core-pulling process, allowing for the easy formation of recesses, protrusions, through holes, and various irregular structures within it. This facilitates the accommodation and protection of precision transmission components or complex wiring structures. Furthermore, during the housing production process, a series of protective measures are implemented for the key support and rotation points on the housing mold. By protecting these support points during mold opening, the service life of the mold can be extended, and the accuracy and stability of the mold opening and closing actions during housing production can be ensured, thereby guaranteeing the molding quality of the housing. The protruding suspension on the inner side of the main body of the casing extends outward, which can increase the possibility of additional space utilization while ensuring the overall strength of the casing. This one-piece molding design of the entire casing makes it easier to process the casing in the machining center, reducing the difficulty and complexity of processing. Moreover, through reasonable structural design, the stress in all parts of the internal cavity can be evenly distributed, avoiding stress concentration. In addition, this molding design fully considers the installation and use of side-mounted accessories. The structure of the casing will not hinder the installation of these accessories, and the normal operation of the accessories will not be affected by its own deformation or vibration during operation.

[0023] Secondly, in this invention, the design of cantilevered reinforcing ribs along the lower edge of the guide rail is a measure to enhance structural stability. The cantilevered reinforcing ribs are similar to a cantilever beam structure, extending outward from the lower edge of the guide rail and reinforcing it. This structure can effectively increase the bending strength and torsional strength of the guide rail. When the ball bearing guide rail pair is subjected to various forces during operation, the reinforcing ribs can evenly distribute the load borne by the ball bearing guide rail pair to the main structure of the housing, ensuring that the ball bearing guide rail pair can maintain a stable working state during high-speed and high-precision movement and preventing excessive deformation of the guide rail.

[0024] Thirdly, in this invention, the design of the oil filling groove and oil filling hole is to ensure that the lubricating oil can flow fully in the required parts. The unique oil groove design ensures that key components can be fully and effectively lubricated, reducing friction and wear between components, improving the working efficiency and motion accuracy of the equipment. Moreover, since the shape, size and position of the oil filling groove and oil filling hole are carefully designed, the lubricating oil can be smoothly discharged according to the preset path after completing the lubrication task, achieving the purpose of standardized oil discharge. This process avoids the accumulation and chaotic flow of lubricating oil inside the casing. The lubricating oil can be collected in a specific area or discharged through a special pipeline, preventing the lubricating oil from contaminating other components or affecting the normal operation of the equipment.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] This invention provides a technical solution: such as Figure 1 - Figure 2 The diagram shows the outer shell structure of an ultra-high-speed computerized embroidery machine head, including a main shell 1; the main shell 1 has an inner shell cavity 2, the shell cavity 2 has an overall trapezoidal structure, and the top of the shell cavity 2 has a slightly arched design.

[0031] It is worth mentioning that: Cavity 2 is the hollow part inside the housing, a space formed by the inner wall of the housing. Cavity 2 is formed using a core-pulling process. This process allows for the easy creation of recesses, protrusions, through holes, and various irregular structures within the cavity, facilitating the housing and protection of precision transmission components or complex wiring structures. This one-piece housing design makes machining in a machining center more convenient. Due to the rational structure, the machining center's cutting tools can more easily reach various machining areas, reducing the difficulty and complexity of machining. For example, during milling and drilling operations, the cutting tools can smoothly follow the preset path without being obstructed by the structure, thereby improving machining efficiency and accuracy. Furthermore, through the rational structural design, The uniform distribution of stress throughout the internal cavity prevents stress concentration, which helps prevent local deformation or damage to the housing during long-term use, thus improving its reliability and durability. The micro-arched design at the top of the housing cavity 2 provides sufficient space to accommodate taller components such as motors. The depth and diameter of the various recesses inside are precisely designed according to the sensor dimensions, which facilitates stable installation and operation of each part inside the housing cavity 2. In addition, the above design means that the housing was designed with full consideration for the installation and use of side-mounted accessories, which may include control cables, auxiliary motors, or other functional modules. The structure of the housing will not hinder the installation of these accessories, and the accessories will not be affected by deformation or vibration during operation.

[0032] Please see Figures 1-2 The cavity 2 of the housing is provided with a connecting plate 3, and a convex suspension 4 is provided on the connecting plate 3. The convex suspension 4 is located inside the main body 1 of the housing, and the front section of the convex suspension 4 is circular.

[0033] The function of the convex suspension 4 is as follows: The convex suspension 4, located inside the main body 1 of the housing, protrudes outward, creating additional space inside the main body 1 of the housing. This space can be used to install some small, specially shaped components, or as a wiring channel, etc. For example, some control elements that do not require much space but are in a critical position can be installed on the convex suspension part, making the internal space of the housing more efficient. In addition, the inner convex suspension structure is designed with full consideration of the overall strength and stability of the housing. Its shape, size and connection method are carefully designed so that while increasing space utilization, it will not interfere with other parts of the housing, nor will it weaken the overall structural strength of the housing.

[0034] Please see Figures 1-2A side plate 5 is provided on one side of the main body 1 of the casing. A back plate 6 is connected to the left end of the connecting plate 3 and the side plate 5. A support assembly is connected to the upper end of the side plate 5 and the back plate 6. The support assembly is used to connect the guide rail. The support assembly includes a connecting platform 7. The edge of the connecting platform 7 is arc-shaped. The right side of the connecting platform 7 and the right side of the connecting plate 3 are located on the same vertical plane.

[0035] The function of the connecting platform 7 is to connect the guide rail and the machine housing, so that the guide rail is firmly fixed on the machine housing. By setting precise mounting holes and positioning structures on the connecting platform 7, the guide rail can be accurately installed according to the design requirements, ensuring the linearity and accuracy of the machine head movement.

[0036] Please see Figures 1-2 The lower edge of the connecting platform 7 is provided with a reinforcing rib 8. The length of the reinforcing rib 8 is greater than the width of the housing cavity 2, and the reinforcing rib 8 has a straight strip structure.

[0037] It is worth mentioning that the cantilevered reinforcing rib 8 designed on the lower edge of the guide rail is a measure to enhance structural stability. The cantilevered reinforcing rib 8 is similar to a cantilever beam structure, extending outward from the lower edge of the guide rail and reinforcing it. This structure can effectively increase the bending strength and torsional strength of the guide rail. When the bead frame guide rail pair is subjected to various forces during operation, the reinforcing rib 8 can evenly distribute the load borne by the bead frame guide rail pair to the main structure of the machine housing, ensuring that the bead frame guide rail pair can maintain a stable working state during high-speed and high-precision movement, and preventing excessive deformation of the guide rail. For example, during the rapid movement or frequent start and stop of the embroidery machine head, the bead frame guide rail pair can be accurately positioned and moved under the support of the cantilevered reinforcing rib 8, ensuring the accuracy and quality of the embroidery.

[0038] Please see Figures 1-2 The upper surface of the connecting platform 7 is provided with an oil injection component, which is used to inject oil into the guide rail. The oil injection component includes an oil injection groove 9 and an oil injection hole 10, which are interconnected.

[0039] It is important to note that the shape, size, and position of the oil filling groove 9 and the oil filling hole 10 are carefully designed to ensure that the lubricating oil can flow fully in the required areas. The unique oil groove design ensures that key components receive sufficient and effective lubrication, reducing friction and wear between components and improving the working efficiency and motion accuracy of the equipment. For example, the oil filling groove 9 may be distributed along key transmission components, bearings, or guide rails, allowing the lubricating oil to accurately reach the friction surface and play a good lubricating role. Furthermore, through the careful design of the oil filling groove 9 and the oil filling hole 10, the lubricating oil can be smoothly discharged along a preset path after completing the lubrication task, achieving the purpose of standardized oil discharge. This process avoids the accumulation and chaotic flow of lubricating oil inside the casing. The lubricating oil can be collected in a specific area or discharged through a dedicated pipeline, preventing the lubricating oil from contaminating other components or affecting the normal operation of the equipment.

[0040] Please see Figures 1-2 The beginning of the oil injection groove 9 is flush with the side plate 5. The oil injection groove 9 has an "L" shaped structure, and the oil injection hole 10 has a circular structure.

[0041] It is worth mentioning that when the opening of the oil injection groove 9 is flush with the side plate 5, it is easier to perform machining operations during the manufacturing process. For example, in the molding process of the machine housing, the side plate 5 can be used as a reference plane, making the machining of the oil injection groove 9 more convenient and precise, and reducing machining errors. When installing oil injection accessories, this flush design also allows the oil injection groove 9 to be better connected to other components (such as oil pipes, oil pumps, etc.) because its opening position is clear and flat, which is conducive to the accurate positioning and sealing installation of the connecting components. The "L"-shaped structure of the oil injection groove 9 can provide lubrication for multiple components in different directions or positions at the same time. For example, in the structure of the embroidery machine head, it can lubricate along the... One direction provides lubrication for the main moving parts such as guide rails, and then the corner section guides the lubricating oil to other adjacent key components, such as bearings and transmission gears. This multi-functional lubrication method allows the oil injection groove 9 to meet the lubrication needs of multiple components in complex mechanical structures, reducing the complexity and cost of setting up an oil injection device for each component individually. When pressure is applied to the oil injection hole 10, the circular structure can make the stress evenly distributed around the hole. Compared with holes of other shapes, the circular oil injection hole 10 is less prone to stress concentration, thereby reducing the risk of fatigue, cracking and other damage to the material around the oil injection hole 10, and ensuring the structural integrity and service life of the oil injection hole 10.
