Description

Technical Field

[0001] This utility model relates to the field of doctor's cap forming technology, and in particular to a doctor's cap forming machine. Background Technology

[0002] A doctor's cap is a type of hat worn by doctors on their heads. During the production and processing of this type of cap, elastic bands need to be installed on the edge of the cap blank, and then it needs to be welded and die-cut to complete the molding process. Therefore, a corresponding molding machine is required.

[0003] For example, Chinese patent CN208192310U discloses a doctor's cap manufacturing machine, belonging to the technical field of automated processing equipment for doctor's caps. A folding and welding wheel assembly is installed on the machine base behind the material rack assembly. Behind the folding and welding wheel assembly is a T-shaped folding assembly. Behind the T-shaped folding assembly is a cap top welding assembly on the machine base. Behind the cap top welding assembly is a folding assembly. Using a T-shaped folding mechanism, the complex fabric folding is completed, simplifying the process. A rolling cut method increases the output to 60 pieces per minute. This doctor's cap manufacturing machine completes everything from non-woven fabric raw materials to finished products. One person can control multiple machines, reducing labor costs. Simultaneously, using an optimized mechanical structure, single-layer non-woven fabric undergoes folding and welding on both sides, T-folding, ultrasonic welding of the cap top, folding and forming, welding of the front and back edges of the doctor's cap, and forming and rolling cut, thus achieving fully automated manufacturing of doctor's caps.

[0004] Although it can complete basic automatic feeding and forming, the position of its roll bar is a fixed structure. When put into production, due to different suppliers or different winding processes, the diameter, size and height of different roll bars are different. At the same time, the height of the roll bar is different when it is intact and when it is half used. This can easily cause fabric wrinkles or deviation, affecting the forming quality.

[0005] Therefore, a doctor's cap forming machine was proposed to solve the above problems. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0016] Example 1 Please see Figure 1-2 This utility model discloses a doctor's cap forming machine. The main body 1 of the device includes a roll assembly, a worktable 4, and a feeding assembly 403. The worktable 4 is equipped with a forming assembly 401, a sealing assembly 402, and a controller 5. The two ends of the worktable 4 are the feeding end and the feeding end, respectively. The roll assembly is arranged at the feeding end for placing and feeding the raw material roll. The roll assembly consists of a roll bar 2, two adjusting frames 301, and a fixing frame 3. The fixing frame 3 is fixedly installed at one end of the worktable 4. The inner side of the fixing frame 3 has an arc-shaped groove 302 corresponding to the height change trajectory of the roll bar 2. The arc-shaped groove 302 has three slots along the height direction: upper, middle, and lower. The two adjusting frames 301 are respectively assembled at both ends of the roll bar 2. Their bottom ends are inserted into the arc-shaped groove 302 and cooperate with the slots to achieve coarse positioning of the roll bar 2 at different heights, thereby adapting to rolls of different diameters and ensuring smooth subsequent feeding.

[0017] Furthermore, the coil bar 2 adopts a detachable and replaceable structure, which facilitates loading and maintenance. The journals at both ends of the coil bar 2 cooperate with the bearing seats of the adjusting frame 301. Rolling bearings or sleeve bearings are installed in the bearing seats to ensure that the coil bar 2 rotates smoothly during feeding and bears radial loads. This structure not only facilitates the quick assembly and disassembly of the coil, but also helps to reduce rotational friction and extend service life.

[0018] Furthermore, the upper slot 3021, the middle slot 3022, and the lower slot 3023 are located at three different heights within the arc-shaped groove 302, arranged sequentially from top to bottom. By selecting different slots as the landing points of the adjusting frame 301, the vertical position of the coil 2 can be changed to accommodate different coil diameters or feeding center heights. A positioning element is provided within the arc-shaped groove 302 to cooperate with the bottom end of the adjusting frame 301 for coarse positioning. The positioning element, when engaged with the slot, ensures the height stability of the coil 2 during operation. The positioning element is used to fix the position of the bottom end of the adjusting frame 301, ensuring rigid positioning of the adjusting frame 301 at the selected slot. During operation, shifting gears can be performed by pulling out or releasing the positioning element; reliably fixing the position is achieved after the positioning element is reset or inserted. Furthermore, the controller 5 is installed on the side of the workbench 4. The controller 5 contains a PLC control component. The PLC is electrically connected to the forming component 401 and the edge sealing component 402 to coordinate the timing and interlocking control of the overall production process. The PLC can realize the linkage of feeding start / stop, tension control signal, synchronization of forming and edge sealing actions, and coordination control with the unloading component 403, thereby ensuring the sequence and safety of each process of feeding, forming, edge sealing and unloading.

[0019] Example 2 This embodiment improves upon the first embodiment by using an electric height adjustment structure. One or both sides of the adjustment frame 301 are connected to the electric drive device. The electric drive realizes the automatic lifting and precise positioning of the coil bar 2 according to the program. The PLC in the controller 5 is electrically connected to the drive unit, motor and position sensor to realize one-key gear switching or preset line switching program.

[0020] In this embodiment, the electric drive uses a servo motor or stepper motor in conjunction with a lead screw or ball screw. The rotation is converted into translation along an arc-shaped trajectory through a connecting rod or guide, thereby driving the bottom end of the adjustment frame 301 to move within the arc-shaped groove 302. To achieve closed-loop control, a servo system with an encoder can be used on the servo motor or a position sensor can be installed on the adjustment frame 301. A proximity switch or final position sensor is configured at each slot to detect the position signal. The PLC controls the drive to decelerate to the target position based on the sensor signal and triggers the automatic locking mechanism to complete rigid locking.

[0021] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0022] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features.
