Description

Technical Field

[0001] This utility model relates to the field of headphone case manufacturing technology, specifically a headphone case production stretching and cutting device. Background Technology

[0002] In the prior art, patent CN222684649U discloses a leather trimming and cutting device for producing headphone cases. The device includes a base with a support fixed to its bottom. Multiple positioning rods pass through the base and support. Two connecting pieces are fixed to the top of a ring, and these pieces are fixed to a lifting plate. A ring-cutting blade is coaxially fixed to the bottom of the ring. The positioning rods position the leather material for the headphone case. An electric cylinder lowers the cutting section, and a pressure plate presses and fixes the leather material, thus limiting its movement. After the ring-cutting blade descends, it cuts off any excess trim at the edge of the leather material. This design eliminates the need for manual cutting when trimming the trim at the edge of the headphone case, improving operational convenience and saving manpower. Furthermore, it allows for simultaneous cutting of multiple headphone cases, increasing processing efficiency.

[0003] While the aforementioned equipment can effectively cut off excess trimmings from leather edges, it presents several problems in practical application: First, after cutting, manual hand insertion is required to remove the shaped earphone leather from under the cutter. This poses a high safety risk due to accidental triggering of the cutter or improper operation. Second, the equipment lacks a waste collection structure, resulting in waste residue remaining on the cutting groove and cutting table surface. During subsequent cutting, this waste will compress and scrape the leather edges, leading to reduced cutting precision, edge damage and deformation, and affecting the quality of the finished product.

[0004] Therefore, a skin-splitting and cutting device for producing headphone cases is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a stretching and cutting device for producing headphone cases, so as to solve the problems mentioned in the background art.

[0021] 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 some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: Please refer to Figure 1-4 This utility model provides a technical solution: a headphone case production lifting and cutting device, including an operating table 1, a mounting frame 2 fixedly installed on the operating table 1, a cutting component 3 fixedly installed on the mounting frame 2, a cutting groove 4 provided on the operating table 1, the cutting component 3 and the cutting groove 4 being adapted to each other, a translation mechanism installed on the operating table 1, the translation mechanism including a guide hole 5, a transmission block 51 slidably installed inside the guide hole 5, a support block 52 fixedly installed on the transmission block 51, the cutting groove 4 being pre-set on the support block 52, a vertical plate 53 fixedly installed on the bottom side of the operating table 1, a lead screw 54 rotatably installed on the vertical plate 53, one end of the lead screw 54 being installed on the operating table 1, an internal thread block 55 threaded onto the lead screw 54, an adapter plate 56 fixedly installed on the internal thread block 55, and the adapter plate 56 being fixedly installed. Mounted on the bottom side of the transmission block 51, a motor plate 57 is fixedly installed on the operating table 1. A forward and reverse motor 58 is fixedly installed on the motor plate 57 by bolts. A reducer 59 is connected to the output shaft of the forward and reverse motor 58. The other end of the reducer 59 is connected to the other end of the lead screw 54. After the leather on the support block 52 is cut by the cutter on the cutting assembly 3, the reducer 59 drives the lead screw 54 to rotate, which drives the support block 52 to move to the left. This makes it easier for workers to remove the leather from the support block 52 without bending over. It also avoids the risk of being accidentally injured by the cutter on the cutting assembly 3 if the leather is picked up directly under the cutter. At the same time, the forward and reverse motor 58 can stop the lead screw 54 when the support block 52 moves to the leftmost or rightmost position, which is convenient for the support block 52 to support.

[0023] Furthermore, the mounting bracket 2 is equipped with a chip removal mechanism for convenient removal of waste chips inside the groove 4 and on the upper surface of the support block 52. The chip removal mechanism is mounted on the translation mechanism and is adapted to the support block 52.

[0024] Specifically, the chip removal mechanism includes two connecting plates 6, which are vertically slidably mounted on both sides of the mounting frame 2. A transfer box 61 is fixedly mounted on each of the two connecting plates 6. A suction hood 62 is mounted on the bottom side of the transfer box 61, and the suction hood 62 is adapted to the cutting groove 4. A vacuum cleaner 63 is provided on one side of the operating table 1, and a suction pipe 64 is fixedly connected to the vacuum cleaner 63. One end of the suction pipe 64 passes through one of the connecting plates 6 and is fixedly mounted on one side of the transfer box 61, communicating with the interior of the transfer box 61. Drive rods 65 are hinged to both ends of the connecting plate 56 via hinge shafts. The other ends of the two drive rods 65 are respectively hinged to the two connecting plates 6 via hinge shafts. When the internal thread block 55 moves to the left, the connecting plate 56 drives the drive rods 65 to rotate clockwise, and the drive rods 65 drive the connecting plate 6 on the mounting frame 2 to move downwards. The connecting plate 6 moves the adapter box 61 downwards, and the adapter box 61 moves the suction hood 62 closer to the cutting groove 4. After the worker removes the leather from the cutting groove 4, the vacuum cleaner 63 can be used to create negative pressure on the adapter box 61, so that the suction hood 62 can suck the waste from the cutting groove 4 and the surface of the support block 52 into the vacuum cleaner 63 for centralized collection. After the leather is processed, the waste collected in the vacuum cleaner 63 is centrally processed. At the same time, in order to improve the operational flexibility and automation, the vacuum cleaner 63 supports two start-up modes: one is manual control, where the worker starts the vacuum cleaner by pressing a button after removing the leather; the other is intelligent control, which is linked to the limit switch of the translation mechanism through the PLC control module. When the support block 52 moves to the left limit position and the leather is removed, the system automatically triggers the vacuum cleaner to start, realizing precise dust removal without human intervention.

[0025] The working principle is as follows: When using this device to cut the earphone case, firstly, lay the leather material to be cut flat on the support block 52, ensuring that the leather material covers the cutting groove 4 area and is aligned with the cutting path of the cutting component 3, in preparation for precise cutting. Start the cutting component 3, and use its built-in cutting mechanism to cut the edge skirt of the leather material on the support block 52 to complete the forming and cutting of the earphone case. After the cutting is completed, start the forward and reverse motor 58. The motor output shaft drives the lead screw 54 to rotate through the transmission. The lead screw 54 drives the internal thread block 55 to move to the left through the thread engagement. The internal thread block 55 drives the adapter plate 56 to move synchronously, and then drives the support block 52 to move to the left side of the mounting bracket 2 along the guide hole 5 through the transmission block 51. At this time, the support block 52 moves the groove 4 and the formed earphone cover inside the groove away from the cutting area of ​​the cutting component 3. The staff can directly remove the formed cover in a safe area without bending over or reaching under the cutter, completely avoiding the risk of accidental injury from the cutter. As the internal thread block 55 moves the adapter plate 56 to the left, the adapter plate 56 simultaneously drives the drive rods 65 at both ends to rotate clockwise. The drive rods 65 push the connecting plates 6 on both sides of the mounting bracket 2 to slide downward. The connecting plates 6 drive the adapter box 61 and the bottom suction hood 62 to move downward simultaneously until the suction hood 62 is close to the groove 4 and the upper surface of the support block 52. After the staff removes the formed cover, the vacuum cleaner 63 is started. The vacuum cleaner 63 creates negative pressure inside the adapter box 61 through the suction pipe 64, and then quickly absorbs the cutting waste residue remaining on the inner wall of the groove 4 and the surface of the support block 52 through the suction hood 62. The waste is collected in the vacuum cleaner 63 through the adapter box 61 and the suction pipe 64. Once all processing tasks are completed, the waste collected inside the vacuum cleaner 63 can be cleaned up.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
