Description

Technical Field

[0001] The present invention belongs to the technical field of eye mask production, and specifically relates to a cutting device for ear straps of Tibetan medicine steam eye masks. Background Art

[0002] During the production of eye masks, different from masks, eye masks generally use wide ear straps, which can evenly disperse the pressure on the ears and head, avoiding discomfort caused by the thin straps being tightened for a long time. It is necessary to cut out ear straps of appropriate length and then fix them by hot pressing. The ear strap material is unwound in the form of a roll, and is stably conveyed through a tension controller. Then, the ear straps are cut according to a preset length, and then the two ends of the ear straps are fixed on both sides of the eye mask body by ultrasonic welding, hot pressing or sewing machines.

[0003] When cutting the ear strap material, since the ear strap is in the form of a wide band and is relatively soft itself, the end of the ear strap material is in a soft state and is prone to folding when being clamped, resulting in local over-thickness during welding and prone to quality problems. Therefore, a cutting device for ear straps of Tibetan medicine steam eye masks is proposed. Summary of the Invention

[0004] To solve the problem of folding easily occurring at the clamping part proposed in the above background art, the present invention provides a cutting device for ear straps of Tibetan medicine steam eye masks.

[0005] To achieve the above object, the present invention provides the following technical solution: A cutting device for ear straps of Tibetan medicine steam eye masks, including a workbench, a main frame is installed on the top of the workbench, and ear strap material is placed inside the main frame. It further includes:

[0006] A pulling assembly, which is installed on the top of the workbench for pulling a sufficient length of ear strap material;

[0007] A feeding assembly, which is installed on the top of the workbench for guiding the ear strap material;

[0008] Among them, the pulling assembly includes a first linear guide rail fixedly connected to the top of the workbench, a pneumatic slider is slidably connected inside the first linear guide rail, and a pair of first clamping jaws are hinged on the top of the pneumatic slider;

[0009] The feeding assembly includes a base fixedly connected to the workbench, a pair of second clamping jaws are hinged at one end of the base, and movable stop rods are movably connected inside the second clamping jaws.

[0010] Preferably, the first linear guide rail corresponds to the position of the base. One end of the first linear guide rail is fixedly connected with a pressing block. The first clamping jaws are distributed vertically, and a first elastic member is fixedly connected to the middle of a pair of first clamping jaws. Limit blocks are arranged inside the first clamping jaws. Straight grooves are formed on the outer sides of the joints between the first clamping jaws and the workbench. A limit baffle is slidably connected to the outer sides of the first clamping jaws.

[0011] Preferably, the limit blocks are in the shape of an inclined bevel rectangle, and the sides of the limit blocks facing the base are inclined from bottom to top towards the base. A channel is reserved between the bottom of the limit blocks and the first clamping jaws. The first elastic member is located on the side close to the base at the joint between the first clamping jaws and the workbench.

[0012] Preferably, the limit baffle surrounds the outer sides of the first clamping jaws. Slide bars are arranged at the positions corresponding to the straight grooves on the inner sides of the limit baffle. The slide bars slide inside the straight grooves. The slide bars inside the limit baffle are at the same horizontal position as the joints between the first clamping jaws and the pneumatic slider. One end of the limit baffle abuts against the pressing block.

[0013] Preferably, limit rods are rotatably connected inside the second clamping jaws. The movable stop rods slide at one ends of the limit rods. Second elastic members are fixedly connected between the middle of the limit rods and the second clamping jaws. A pair of inclined surface stop blocks and a pair of limit top plates are fixedly connected to one side of the base where the second clamping jaws are located. A third elastic member is fixedly connected between the inclined surface stop blocks and the second clamping jaws.

[0014] Preferably, ear strap materials are clamped in the middle of the second clamping jaws. The second clamping jaws are movably connected to the middle of the first clamping jaws. The movable stop rods abut against the limit blocks. The tops of the second clamping jaws are inclined. The inclined surfaces of the inclined surface stop blocks are parallel to the second clamping jaws. The limit top plates are distributed on both sides of the second clamping jaws, and the limit top plates abut against the limit baffle.

[0015] Preferably, when the movable stop rods abut against the limit blocks, the movable stop rods are squeezed by the limit blocks and slide downward into the channels between the limit blocks and the first clamping jaws. At the same time, the second elastic members are squeezed by the limit rods to the compressed state. After the limit blocks pass over the movable stop rods, the second elastic members rebound and push the movable stop rods upward through the limit rods.

[0016] Preferably, when the pneumatic slider drives the first clamping jaws to move to the second clamping jaws, the limit baffle will abut against the limit top plates at this time. Then the limit top plates limit the limit baffle. When the pneumatic slider drives the first clamping jaws to continue to move, the sliding rods inside the straight grooves will slide along the straight grooves at this time. The first clamping jaws are limited by the slide rods of the limit baffle, so that the first clamping jaws clamp the ear strap materials.

[0017] Preferably, a conveyor belt is provided in the middle of the workbench, which passes through the bottom of the main frame. The pulling assembly and the feeding assembly are mirror-distributed on both sides of the conveyor belt, and both the pulling assembly and the feeding assembly are located below the main frame.

[0018] Preferably, ear tape clamping claws are installed at the bottom of the main frame, and a mobile cutting mechanism is arranged on the side of the base. The cutting edge of the mobile cutting mechanism is located at the end of the second claw. When the ear tape clamping claws are in the open state, the unfolded ear tape is located inside the opening of the ear tape clamping claws.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] Through the cooperation of structures such as the pulling assembly and the second claw, the present invention facilitates the clamping of the ear tape. By clamping the ear tape with the second claw, the ear tape is kept in an unfolded state as a whole. When the first claw moves to the second claw to clamp the ear tape, the ear tape will not be folded. Moreover, while the ear tape is being pulled and unfolded by the second claw, the second claw can keep the ear tape stable and will not fold towards the middle.

[0021] Through the cooperation of structures such as the limiting rod and the movable stop rod, the present invention facilitates the control of the opening and closing of the second claw. The arrangement of the limiting rod and the movable stop rod can control the opening of the second claw, so that when the end of the ear tape starts to be pulled out by the first claw, the second claw is in the open state, avoiding pulling the ear tape off from the first claw. When the first claw pulls the end of the ear tape out, at this time, the second claw will be pushed by the third elastic member to close again to stably clamp the ear tape and keep the ear tape unfolded.

[0022] Through the cooperation of structures such as the limiting baffle and the limiting top plate, the present invention controls the opening and closing of the first claw. By setting the limiting top plate, after the limiting baffle abuts against the limiting top plate, the limiting baffle cannot move further, but the first claw can continue to move. Then, the sliding rod inside the limiting baffle slides in the straight groove to limit one end of the first claw, so that the first claw closes to clamp the ear tape. When the limiting baffle moves to abut against the extrusion block, the pneumatic slider can continue to move, releasing the limit of the first claw by the limiting baffle, and the first claw is pushed by the first elastic member to open. By sliding at both ends of the pneumatic slider, the closing and opening of the first claw are realized, and no additional equipment is required for control. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] As Figures 1 to 6 shown, the present invention provides a Tibetan medicine steam eye mask earband cutting device, including a workbench 1, a main body frame 2 is installed on the top of the workbench 1, and earband material 7 is placed inside the main body frame 2. The device further includes:

[0032] A pulling component 4, which is installed on the top of the workbench 1 for pulling the earband material 7 to a sufficient length;

[0033] A feeding component 5, which is installed on the top of the workbench 1 for guiding the earband material 7;

[0034] Among them, the pulling component 4 includes a first linear guide rail 401 fixedly connected to the top of the workbench 1, a pneumatic slider 402 is slidably connected inside the first linear guide rail 401, and a pair of first clamping jaws 403 are hinged to the top of the pneumatic slider 402;

[0035] The feeding assembly 5 includes a base 501 fixedly connected to the workbench 1. At one end of the base 501, a pair of second clamping jaws 503 are hinged, and movable stop rods 505 are movably connected inside the second clamping jaws 503.

[0036] Adopting the above solution: The pneumatic slider 402 drives the first clamping jaw 403 to slide along the first linear guide 401 towards the base 501. When the first clamping jaw 403 moves to the position of the second clamping jaw 503, at this time, the first clamping jaw 403 is in an open state under the extrusion of the first elastic member 406, and the ear strap material 7 can stably enter the inside of the first clamping jaw 403. Then, the second clamping jaw 503 enters the middle of the first clamping jaw 403. At the same time, the limit top plate 509 abuts against the limit baffle 407. At this time, the limit baffle 407 remains stationary, but the first clamping jaw 403 continues to move under the push of the pneumatic slider 402, causing the sliding rod inside the limit baffle 407 to slide inside the straight groove 405, so that one end of the first clamping jaw 403 is extruded, and then gradually closes towards the end of the second clamping jaw 503, and the ear strap material 7 is clamped by the first clamping jaw 403;

[0037] When the pneumatic slider 402 resets, at this time, the movable stop rod 505 has reset and is higher than the low point of the inclined surface of the limit block 404. Therefore, the movable stop rod 505 will abut against the limit block 404 and be pushed by the extrusion of the limit block 404, driving the second clamping jaw 503 to move towards the side away from the ear strap material 7, so that the second clamping jaw 503 releases the clamping of the ear strap material 7. Then, it is convenient to pull out the ear strap material 7 from the second clamping jaw 503. When the first clamping jaw 403 pulls out the ear strap material 7, at this time, the ear strap clamping claws 3 and the movable cutting mechanism 6 can be started to move towards the ear strap material 7. When the limit baffle 407 moves to abut against the extrusion block 408, at this time, the ear strap clamping claws 3 and the movable cutting mechanism 6 have moved to the position of the ear strap material 7, and the ear strap clamping claws 3 clamp the ear strap material 7. Then, the movable cutting mechanism 6 cuts the ear strap material 7. After that, the pneumatic slider 402 continues to move, releasing the limit of the limit baffle 407 on the first clamping jaw 403, so that the first clamping jaw 403 is pushed by the first clamping jaw 403 to open, thus completing the cutting of the ear strap material 7.

[0038] As Figures 2 to 4 shown, the first linear guide 401 corresponds to the position of the base 501. One end of the first linear guide 401 is fixedly connected with an extrusion block 408. The first clamping jaws 403 are distributed up and down, and a first elastic member 406 is fixedly connected to the middle of a pair of first clamping jaws 403. Limit blocks 404 are arranged inside the first clamping jaws 403. Straight grooves 405 are opened on the outer sides of the joints where the first clamping jaws 403 are hinged to the workbench 1. A limit baffle 407 is slidably connected to the outside of the first clamping jaws 403.

[0039] Adopt the above solution: By setting the pulling component 4, the pneumatic slider 402 drives the first jaw 403 to move, so that the first jaw 403 moves to the second jaw 503 to clamp the end of the earband material 7, and then the earband material 7 is pulled to be unfolded for shearing the earband material 7. The first jaw 403 is provided for clamping the earband material 7. The first elastic member 406 provided in the middle of the first jaw 403 keeps the first jaw 403 in an open state to ensure that when the first jaw 403 moves to the second jaw 503, the earband material 7 is inside the first jaw 403. The straight groove 405 and the limit baffle 407 are provided to control the opening and closing and locking of the first jaw 403.

[0040] As Figures 3 to 6 shown, the limit block 404 is in the shape of an inclined bevel rectangle, and at the same time, the sides of the limit block 404 facing the base 501 are inclined from bottom to top towards the base 501. A channel is reserved between the bottom of the limit block 404 and the first jaw 403. The first elastic member 406 is located on the side of the hinge joint between the first jaw 403 and the workbench 1 close to the base 501. The limit baffle 407 surrounds the outside of the first jaw 403. A slide bar is provided at a position corresponding to the straight groove 405 on the inner side of the limit baffle 407, and the slide bar is slidably connected inside the straight groove 405. The slide bar inside the limit baffle 407 is at the same horizontal position as the hinge points of the first jaw 403 and the pneumatic slider 402. One end of the limit baffle 407 abuts against the extrusion block 408.

[0041] Adopt the above solution: By the limit block 404 provided inside the first jaw 403, the second jaw 503 can be pressed down when the first jaw 403 clamps the end of the earband material 7 to keep the clamping of the earband material 7 stable, and when the first jaw 403 initially pulls the earband material 7 to move from the second jaw 503, the second elastic member 506 opens the second jaw 503 to facilitate the movement of the earband material 7;

[0042] By setting the hinge point of the straight groove 405 and the pneumatic slider 402 at the same horizontal position, when the slide bar on the limit baffle 407 is at the hinge joint between the pneumatic slider 402 and the first jaw 403, the end of the first jaw 403 is not limited at this time, so that the first elastic member 406 can push the first jaw 403 to unfold. When the slide bar on the limit baffle 407 moves to the other end of the straight groove 405, the slide bar will limit the first jaw 403 through the straight groove 405 at this time, so that the first jaw 403 is squeezed, thereby closing to clamp the earband material 7.

[0043] As Figures 4 to 6As shown in the figure, a limiting rod 504 is rotatably connected inside each of the second clamping jaws 503. An active stop lever 505 slides on one end of the limiting rod 504. A second elastic member 506 is fixedly connected between the limiting rod 504 and the second clamping jaw 503. On one side of the second clamping jaw 503, a base 501 is fixedly connected with a pair of inclined surface stoppers 507 and a pair of limiting top plates 509. A third elastic member 508 is fixedly connected between the inclined surface stopper 507 and the second clamping jaw 503.

[0044] With the above solution: By providing the feeding assembly 5, the conveying roller 502 guides the ear strap material 7, and the second clamping jaw 503 clamps and supports the end of the ear strap material 7 to prevent the ear strap material 7 from folding. The arrangement of the limiting rod 504 and the active stop lever 505 can control the opening of the second clamping jaw 503, so that when the end of the ear strap material 7 is started to be pulled out by the first clamping jaw 403, the second clamping jaw 503 is in an open state, preventing the ear strap material 7 from being pulled off from the first clamping jaw 403. When the first clamping jaw 403 pulls the end of the ear strap material 7 out, at this time, the second clamping jaw 503 will be pushed by the restoration of the third elastic member 508 to close again. However, at this time, the first clamping jaw 403 has already pulled the end of the ear strap material 7 out from the second clamping jaw 503. At this time, the clamping of the ear strap material 7 by the second clamping jaw 503 is not sufficient to pull the ear strap material 7 off from the middle of the first clamping jaw 403, and it can keep the ear strap material 7 in a flattened and straightened state.

[0045] As shown in the figure, the ear strap material 7 is clamped in the middle of the second clamping jaw 503. The second clamping jaw 503 is movably connected to the middle of the first clamping jaw 403. The active stop lever 505 abuts against the limiting block 404. The top of the second clamping jaw 503 is inclined. The inclined surface of the inclined surface stopper 507 is parallel to the second clamping jaw 503. The limiting top plates 509 are distributed on both sides of the second clamping jaw 503 and abut against the limiting baffle 407. When the active stop lever 505 abuts against the limiting block 404, at this time, the active stop lever 505 is squeezed by the limiting block 404 and slides downward into the channel between the limiting block 404 and the first clamping jaw 403. At the same time, the second elastic member 506 is squeezed by the limiting rod 504 to a compressed state. After the limiting block 404 passes over the active stop lever 505, at this time, the second elastic member 506 rebounds and pushes the active stop lever 505 to move upward through the limiting rod 504. When the pneumatic slider 402 drives the first clamping jaw 403 to move to the second clamping jaw 503, at this time, the limiting baffle 407 will abut against the limiting top plate 509. Then, the limiting top plate 509 limits the limiting baffle 407. When the pneumatic slider 402 drives the first clamping jaw 403 to continue moving, at this time, the sliding rod inside the straight groove 405 will slide along the straight groove 405, and the limiting baffle 407's sliding rod limits the first clamping jaw 403, so that the first clamping jaw 403 clamps the ear strap material 7.

[0046] The above solution is adopted: the movable blocking rod 505 is slidably connected to the limit rod 504 and the second clamping jaw 503, so as to slide vertically within a certain range. At the same time, the setting of the limit rod 504 and the second elastic member 506 ensures that the movable blocking rod 505 is in a stable position when not squeezed, so that when the movable blocking rod 505 contacts the limit block 404, it will directly move downward along the oblique edge of the limit block 404, so that the second clamping jaw 503 is tightly closed. After crossing the limit block 404, it will directly reset and move upward to the low point of the oblique surface of the limit block 404, and then it can move along the oblique surface of the limit block 404, so that the second clamping jaw 503 is opened.

[0047] The setting of the limiting top plate 509 controls the closing of the first clamping jaw 403. By setting the limiting top plate 509, after the limiting baffle 407 collides with the limiting top plate 509, the limiting baffle 407 cannot continue to move, but the pneumatic slider 402 can drive the first clamping jaw 403 to continue to move, thereby causing the sliding rod inside the limiting baffle 407 to slide inside the straight groove 405, and then one end of the first clamping jaw 403 will be limited by the sliding rod of the limiting baffle 407, so that the first clamping jaw 403 is closed to clamp the ear band material 7.

[0048] like Figures 1 to 3 As shown, a conveyor belt is provided in the middle of the workbench 1, which passes through the bottom of the main frame 2. The pulling component 4 and the feeding component 5 are distributed on both sides of the conveyor belt in a mirror-image manner. The pulling component 4 and the feeding component 5 are both located on the lower side of the main frame 2. An ear band clamping claw 3 is installed at the bottom of the main frame 2, and a movable shearing mechanism 6 is provided on the side of the base 501. The cutting edge of the movable shearing mechanism 6 is located at the end of the second clamping claw 503. When the ear band clamping claw 3 is in the open state, the unfolded ear band material 7 is located inside the opening of the ear band clamping claw 3.

[0049] The above solution is adopted: by providing the ear strap clamping claw 3, it is convenient to clamp the cut ear strap material 7 and move it to the conveyor belt for welding with the eye mask. The mobile shearing mechanism 6 is used to shear the ear strap material 7 to control the length of the ear strap material 7;

[0050] It is worth noting that the ear strap clamping claws 3 and the movable shearing mechanism 6 belong to the existing technology in this field, and according to different needs, the styles and shapes are different, so they are not described in detail.

[0051] Working principle and usage process of the present invention: When in use, first start the pneumatic slider 402 to drive the first jaw 403 to slide along the first linear guide 401 towards the base 501. When the first jaw 403 moves to the position of the second jaw 503, at this time, the first jaw 403 is in an open state under the extrusion of the first elastic member 406, and the ear strap material 7 can stably enter the inside of the first jaw 403. Then, the second jaw 503 enters the middle of the first jaw 403. At the same time, the limit top plate 509 abuts against the limit baffle 407. At this time, the limit baffle 407 remains stationary, but the first jaw 403 continues to move under the push of the pneumatic slider 402, causing the slide bar inside the limit baffle 407 to slide inside the straight groove 405, so that one end of the first jaw 403 is extruded, and then gradually closes towards the end of the second jaw 503, and the ear strap material 7 is clamped by the first jaw 403;

[0052] At the same time, the movable stop rod 505 inside the second jaw 503 is extruded by the limit block 404 and closes towards the ear strap material 7 and then enters the channel inside between the limit block 404 and the first jaw 403. And the second elastic member 506 extrudes the second jaw 503 to make the clamping of the second jaw 503 more stable, preventing the ear strap material 7 from being pushed out from the middle of the second jaw 503 by the first jaw 403. Then, the second elastic member 506 passes over the limit block 404 and is pushed to reset by the reset limit rod 504 of the second elastic member 506. At this time, the first jaw 403 completes the clamping of the ear strap material 7, and then the pneumatic slider 402 pulls the first jaw 403 to reset;

[0053] When the pneumatic slider 402 resets, at this time the movable stop rod 505 has been reset and is higher than the low point of the inclined surface of the limit block 404. Therefore, the movable stop rod 505 will abut against the limit block 404 and be extruded and pushed by the limit block 404, driving the second jaw 503 to move towards the side away from the ear strap material 7, so that the second jaw 503 releases the clamping of the ear strap material 7. Then it is convenient to pull out the ear strap material 7 from the second jaw 503. When the first jaw 403 pulls out the ear strap material 7, at this time, the ear strap clamping claw 3 and the mobile shearing mechanism 6 can be started to move towards the ear strap material 7. When the limit baffle 407 moves to abut against the extrusion block 408, at this time, the ear strap clamping claw 3 and the mobile shearing mechanism 6 have moved to the position of the ear strap material 7, and the ear strap clamping claw 3 clamps the ear strap material 7. Then, the mobile shearing mechanism 6 shears the ear strap material 7. After that, the pneumatic slider 402 continues to move, releasing the limit of the limit baffle 407 on the first jaw 403, so that the first jaw 403 is pushed to open by the first elastic member 406, thus completing the shearing of the ear strap material 7.
