Description

Technical Field

[0001] This utility model relates to the field of umbrella processing equipment, and in particular to an umbrella tip burning machine. Background Technology

[0002] As an indispensable daily necessity, the optimization and improvement of umbrella manufacturing processes are of great significance for improving product quality and production efficiency. In the umbrella manufacturing process, attaching the handle to the umbrella head (the end of the central shaft) is one of the key steps.

[0003] Traditional manufacturing methods primarily rely on manual hammering by workers. This involves attaching the plastic umbrella handle to the umbrella head and hammering the handle to create a snap-fit ​​connection. However, this manual method has several drawbacks. Firstly, the inconsistent force and frequency of manual hammering can easily lead to a weak connection between the handle and the head, affecting the overall quality of the umbrella. Secondly, prolonged manual hammering is physically demanding, placing a significant burden on workers and resulting in low production efficiency, making it difficult to meet the demands of large-scale production.

[0004] With technological advancements, umbrella handle shaping machines have been applied to the processing of umbrella handles. For example, the applicant's previously filed Chinese patent CN207014806U discloses a safe and energy-saving umbrella handle shaping machine. This machine includes a chassis and a punch structure. A worktable is located on top of the chassis. A conveyor belt drive motor and a centrifugal fan are fixed to the left side of the chassis. The main conveyor roller assembly is connected via a conveyor belt. The punch drive motor is mounted on the front of the chassis. A connecting pulley inside the punch structure is connected to the punch drive motor, and an operation panel is located on the worktable on the right side of the punch structure. This machine deforms the round umbrella handle by striking it with a small punch press, replacing manual striking with a motor-driven method. This achieves uniform striking and reduces labor intensity. Simultaneously, high-frequency heating replaces the original gas heating, improving safety and reliability, and to some extent promoting the automation and standardization of umbrella handle installation.

[0005] However, the above-mentioned technical solutions still have some problems that need to be solved in practical applications. In this umbrella head stamping machine, a conveyor belt is used to transport the umbrella body to be processed, and the umbrella head is stamped before heating. During the conveying process, a single-sided positioning mechanism is used to position and constrain the umbrella head, that is, the umbrella body is placed flat on the conveyor belt, and the outer end of the umbrella head is against the back plate of the rear side of the conveyor belt. However, since the umbrella body on the conveyor belt is in a state where the umbrella cloth is rolled up around the umbrella ribs, the tightness of the rolled umbrella cloth varies among different umbrella bodies. This directly leads to differences in the outer diameter, which in turn causes the umbrella head height of different umbrellas on the conveyor belt to be inconsistent. This difference in umbrella head height will have varying degrees of impact on the stamping quality during the stamping process. If the difference is too large, it can easily lead to stamping instability, resulting in problems such as uneven umbrella head deformation and inaccurate stamping dimensions, which seriously affects the quality of the umbrellas and production efficiency.

[0006] Furthermore, existing umbrella tip-sealing machines suffer from poor adaptability due to their inability to effectively control umbrella tip height, typically only capable of processing umbrellas of a single specification. When faced with processing demands for different batches and specifications of umbrellas, adjustments to the equipment or the adoption of other auxiliary measures are often necessary. This not only increases production costs and timelines but also limits the widespread application and promotion of umbrella tip-sealing machines. Therefore, developing an umbrella tip-sealing machine with effective umbrella tip height control capabilities is of significant practical importance. Utility Model Content

[0007] This invention provides an umbrella tip-burning machine, which helps to solve the problem that some current tip-burning machines do not have effective umbrella tip height control capabilities and are prone to unstable umbrella tip punching.

[0008] This utility model is implemented as follows: The umbrella head burning machine includes a frame with a worktable on top. A horizontally arranged conveyor belt is connected to the worktable, and a conveyor drive unit is connected to the conveyor belt. The top of the conveyor belt is used to place the processed umbrella parts. A stamping device is located in the middle of the worktable, behind the conveyor belt. The stamping device has a punch that can be raised and lowered longitudinally for stamping. A material guiding device and a heating device are respectively located on the front and rear sides of the stamping device relative to the feeding direction of the conveyor belt. The material guiding device includes a baffle and a guide plate. When the umbrella head of the processed umbrella part is placed on the conveyor belt, the rear end of the umbrella head can abut against the front side wall of the baffle to form a single-sided positioning structure. The length direction of the guide plate is parallel to the feeding direction of the processed umbrella part. The guide plate can form a bottom support and positioning structure for the umbrella head during the process of the processed umbrella part moving from the feeding end to the stamping device. Several spaced elastic support members are provided between the bottom of the guide plate and the worktable. A disengagement control structure is provided between the elastic support members and the guide plate.

[0009] Based on the above technical solution, the conveyor belt is wound around a number of conveyor rollers, the conveyor rollers are movably connected to the frame, and the conveyor rollers are connected to the conveyor drive component, which is a geared motor fixed on the frame.

[0010] Based on the above technical solution, the bottom of the punch is provided with a base, and the punch and the base form a punching space for the umbrella head. The base is provided with a detachable inner pad block, and the top of the inner pad block is provided with a groove that fits the outer contour of the bottom of the umbrella head. The groove is provided with anti-slip texture.

[0011] Based on the above technical solution, the guide vanes are spaced apart on the front side of the baffle, and the guide vanes and the baffle form an "L"-shaped positioning structure corresponding to the end structure of the umbrella head.

[0012] Based on the above technical solution, the guide plate has a three-segment broken line structure in its length direction, with the front and rear sides being horizontal segments with one low and one high, and the middle being an inclined segment.

[0013] Based on the above technical solution, the elastic support component includes a sleeve fixed to the workbench. The sleeve has a vertical through-hole structure inside, and a support rod is inserted into the through-hole inside the sleeve. The support rod can slide up and down relative to the sleeve. The support rod has at least two longitudinally spaced insertion holes that radially penetrate the support rod. A pin is detachably inserted into the insertion hole. The pin inserted into the insertion hole can form a locking structure at the bottom of the sleeve to restrict the upward movement of the support rod. A support plate is provided at the top of the support rod. The top contour of the support plate can form a fitting and abutting structure with the bottom contour of the guide plate directly above it. A spring abuts between the bottom of the support plate and the top of the sleeve. The spring can drive the support rod to slide upward relative to the sleeve.

[0014] Based on the above technical solution, the top of the tray is provided with a magnet, the guide plate is made of magnetic metal material, and the tray can form a magnetic connection structure after being attached to the guide plate.

[0015] Based on the above technical solution, the pin is provided with an anti-slip sleeve.

[0016] Compared with the prior art, the present invention has at least the following advantages: This invention, through the design of a material guiding device, particularly the cooperation between the guide plate and the elastic support component, can automatically adjust the support height of the guide plate according to the height differences of the umbrella head caused by the varying tightness of the umbrella fabric roll, thus achieving effective control over the umbrella head height. During the conveying process, the guide plate consistently provides stable bottom support and positioning for the umbrella head, avoiding instability in the stamping process caused by excessive height differences in the umbrella head. This significantly improves the stamping quality, making the umbrella head stamping more uniform and accurate, and ensuring the overall quality of the umbrella.

[0017] In this invention, the "L"-shaped positioning structure formed by the baffle and guide plate in the material guiding device, as well as the stable connection between the guide plate and the elastic support, provides all-round, multi-layer positioning protection for the umbrella head. During the conveying process, the umbrella head can not only achieve horizontal positioning on one side, but also obtain stable support and guidance at the bottom, effectively preventing the umbrella head from shaking and shifting during conveying and punching, thus ensuring the accuracy and stability of processing.

[0018] This invention utilizes a disengagement control structure between the elastic support and the guide plate to flexibly control the actual number of working elastic support components, thereby adjusting the elastic support strength at the bottom of the guide plate. This allows it to adapt to the processing needs of various specifications of umbrella components. Attached Figure Description

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0026] Combination Figures 1 to 6 This embodiment discloses an umbrella burnishing machine including a frame 100. The frame 100 is a skeleton welded from galvanized square tubing and enclosed in a cabinet structure using aluminum alloy panels. The frame 100 serves as the supporting structure for the entire equipment, providing a stable mounting base for other components. A worktable 110 is provided at the top of the frame 100. The worktable 110 is the mounting platform for various processing devices and components; its flatness and strength are crucial for ensuring the normal operation and processing accuracy of the equipment. The bottom of the frame 100 is equipped with adjustable legs, which can be flexibly adjusted according to the actual assembly site for calibration and debugging.

[0027] A horizontally arranged conveyor belt 200 is connected to the workbench 110. The conveyor belt 200 is used to place and transport the processed umbrella parts a. The conveyor belt 200 is connected to a conveyor drive, which provides power to the conveyor belt 200, ensuring that the processed umbrella parts a can move at a predetermined speed and direction. In this embodiment, the conveyor belt 200 is wound around several conveyor rollers 210. The conveyor rollers 210 are movably connected to the frame 100 via bearings, allowing for flexible rotation to reduce frictional resistance during transport. The conveyor rollers 210 are connected to the conveyor drive, which is preferably a geared motor 220 fixed to the frame 100. The geared motor 220 has advantages such as stable operation and adjustable speed, and can precisely control the running speed of the conveyor belt 200 according to actual production needs. During operation, the processed umbrella parts a are arranged in a front-to-back axial direction and placed side-by-side on the conveyor belt 200. Figure 1 The left side of the conveyor belt 200 is the feeding end, and the right side is the discharge end. During the process of processing umbrella part a from the feeding end to the discharge end, it is first guided by the guiding device, then punched by the stamping device 300, and finally heated by the heating device 600 to heat the umbrella head b, making the subsequent insertion with the umbrella handle more efficient and convenient.

[0028] A stamping device 300 is located in the middle of the workbench 110, behind the conveyor belt 200, and is the core component for stamping the umbrella head b. The stamping device 300 has a punch 310 capable of longitudinally lifting and lowering for stamping. The punch 310 moves up and down under the action of a drive mechanism (a cylinder positioned above the punch 310; in other embodiments, an electric cylinder, hydraulic cylinder, or other drive mechanism may also be used), applying pressure to the umbrella head b to deform it and form the desired shape and size. A base 320 is located at the bottom of the punch 310, forming a stamping space for the umbrella head b between the base 320 and the punch 310, providing a suitable spatial environment for the stamping of the umbrella head b. When the processed umbrella part a moves to the stamping area along with the conveyor belt 200, the umbrella head b will pass laterally through the stamping space. When the umbrella head b reaches the stamping station, the punch 310 quickly descends to perform the stamping action. It should be noted that the detection of the umbrella head b reaching the stamping station can be achieved with the help of sensors, such as infrared sensors. These are existing technologies, and their specific structures and working principles will not be described in detail here. Those skilled in the art can select and implement them from existing technologies based on actual operating conditions.

[0029] Furthermore, in combination Figure 6As shown, the base 320 is equipped with a removable inner pad 321. The top of the inner pad 321 has a groove that adapts to the outer contour of the bottom of the umbrella head b, and the groove has anti-slip texture 322. The removable inner pad 321 design allows for easy replacement of the corresponding inner pad 321 according to the shape and size of the umbrella head b of different specifications, thereby achieving precise stamping of umbrella head b of different specifications. The groove design provides a more stable bottom limiting effect for the umbrella head b during stamping, thereby improving the stamping effect. The anti-slip texture 322 increases the friction between the umbrella head b and the inner pad 321, preventing the umbrella head b from sliding during the stamping process and ensuring the stability and accuracy of the stamping.

[0030] The stamping device 300 is equipped with a guiding device and a heating device 600 on its front and rear sides relative to the feeding direction of the conveyor belt 200. The heating device 600 is used to heat the umbrella head b to bring it to a suitable temperature for subsequent hot-melt insertion into the umbrella handle. The heating device 600 uses the principle of electromagnetic eddy currents to generate high temperature, which can indirectly heat the metal umbrella head. Specifically, in this embodiment, the heating device 600 is a high-frequency heating machine, which is existing technology. Its specific structure and working principle can be found in relevant documents such as patent CN201182016Y, and will not be repeated here. Those skilled in the art can select and implement the device from the existing technology according to the actual operation.

[0031] The material guiding device includes a baffle 400 and a guide plate 500. The baffle 400 is a vertical plate structure, and its bottom is fixedly connected to the worktable 110. When the umbrella head b of the processed umbrella piece a is placed on the conveyor belt 200, the rear end of the umbrella head b can abut against the front side wall of the baffle 400 to form a single-sided positioning structure. This single-sided positioning structure can initially position the umbrella head b in the conveying direction, so that the processed umbrella piece a can be placed side by side on the conveyor belt 200 and move in an orderly manner, ensuring that the umbrella head b will not deviate excessively during the conveying process.

[0032] The length direction of the guide plate 500 is parallel to the feeding direction of the processed umbrella part a. The guide plate 500 can form a bottom support and positioning structure for the umbrella head b during the process of the processed umbrella part a moving from the unloading end to the stamping device 300. The guide plates 500 are spaced apart on the front side of the baffle 400, combined with Figure 2 As shown, the guide vane 500 and the baffle 400 constitute an "L"-shaped positioning structure corresponding to the end structure of the umbrella head b. This "L"-shaped positioning structure can position the umbrella head b from two directions, further improving the positioning accuracy. Combined with... Figure 3As shown, the guide plate 500 has a three-segment zigzag structure along its length, with horizontal segments at the front and rear, one low and one high, and an inclined segment in the middle. This special design allows the guide plate 500 to appropriately lift the umbrella head b during movement, providing stable support and guidance for the umbrella head b during transport, thereby reducing the impact of the difference in the outer diameter of the processed umbrella part a on the height of the umbrella head b.

[0033] Several spaced elastic support members 700 are provided between the bottom of the guide plate 500 and the worktable 110. A disengagement control structure is provided between the elastic support members 700 and the guide plate 500. This disengagement control structure allows the user to flexibly control the working state of each elastic support member 700 and select the active or idle mode.

[0034] Specifically, in combination Figure 4 As shown, the elastic support 700 includes a sleeve 710 fixed on the worktable 110. The sleeve 710 has a vertical through-hole structure inside, and a support rod 720 is inserted into the through-hole inside the sleeve 710. The support rod 720 can slide up and down relative to the sleeve. The support rod 720 has two longitudinally spaced insertion holes 721 on its body. The insertion holes 721 radially penetrate the support rod 720. A pin 730 is detachably inserted into the insertion hole 721. The pin 730 inserted into the insertion hole 721 can form a locking structure at the bottom of the sleeve to restrict the upward movement of the support rod 720. A support plate 722 is provided at the top of the support rod 720. The top contour of the support plate 722 can form a close abutment structure with the bottom contour of the guide plate 500 directly above it. A spring abuts between the bottom of the support plate 722 and the top of the sleeve. The spring can drive the support rod 720 to slide upward relative to the sleeve. The design of this elastic support component 700 allows the guide plate 500 to automatically adjust its support position according to the actual height of the umbrella head b, ensuring that the umbrella head b maintains a stable positioning state throughout the conveying process. Simultaneously, this locking structure is the disengagement control structure described above. Figure 4 The pin 730 is inserted into the bottom socket 721, which makes the top of the support rod 720 high enough to touch the upper guide plate 500. If the pin 730 is pulled out, the support rod 720 is pulled down and the pin 730 is inserted into the top socket 721. At this time, the length of the top of the support rod 720 is shortened, and the top support plate 722 cannot touch the upper guide plate 500. This switches the elastic support 700 from the participation mode to the idle mode. In actual application, if the size of the umbrella part a is small or the weight is light, the number of elastic support parts 700 can be reduced to improve the elastic support sensitivity and make the guide support stable.

[0035] To further enhance the connection stability between the deflector 500 and the elastic support 700, such as Figure 4As shown, a magnet 723 is provided on the top of the support plate 722, and the guide plate 500 is made of magnetic metal material. In this embodiment, the guide plate 500 is made of galvanized sheet with low carbon steel as the base material. After the support plate 722 is attached to the guide plate 500, a magnetic connection structure can be formed. This magnetic connection structure can not only increase the connection strength between the guide plate 500 and the elastic support 700, preventing the guide plate 500 from shaking or falling off during equipment operation, but also facilitate the installation and disassembly of the guide plate 500, improving the maintenance efficiency of the equipment.

[0036] In addition, combined Figure 5 As shown, the pin 730 is provided with an anti-slip sleeve 732. The anti-slip sleeve 732 can increase the friction between the pin 730 and the socket 721, prevent the pin 730 from loosening or falling off during use, and ensure the structural stability of the elastic support 700. To facilitate the installation and removal of the pin 730, a push-pull plate 731 is provided on the outer end of the pin 730.

[0037] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
