Description

Technical Field

[0001] The invention relates to the technical field of mask processing, and in particular to a heat-sealing device used for mask processing. Background Art

[0002] A mask is a sanitary product, generally refers to a device worn on the mouth and nose to filter the air entering the mouth and nose, so as to block harmful gases, odors, and droplets from entering and exiting the wearer's mouth and nose. The mask has a certain filtering effect on the air entering the lungs. When respiratory infectious diseases are prevalent and when working in an environment polluted by dust, wearing a mask is very effective.

[0003] The mask is made of a multi-layer structure. During the production and processing of the mask, the multi-layer material needs to be heat-sealed, and then the ear hooks are placed on the mask, and then heat-sealed again so that the ear hooks can be attached to the mask. However, this processing method has the following shortcomings: the mask on the processing table is not straightened during the production and processing, which makes the mask very easy to tilt during processing, thereby affecting the contact degree between the heat-sealing plate and the mask, and affecting the quality of the mask; when the ear hooks and the mask are heat-sealed, the two ends of the ear hooks need to be manually pulled and pressed onto the mask, which makes the operator's safety during operation not guaranteed, and the position of the ear hooks cannot be ensured, thereby affecting the efficiency of the heat-sealing processing of the mask. Summary of the invention

[0004] The purpose of the present invention is to solve the problem in the prior art that the position of the ear hook rope cannot be ensured during mask processing, and to propose a heat sealing device for mask processing.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] Reference Figure 1-Figure 7 , a heat-sealing device for mask processing, comprising a base 1, and a sealing end for sealing the mask is provided on the base 1, and the mask can be heat-sealed after the sealing end is powered on. This technical solution is a prior art and will not be elaborated on here;

[0030] The base 1 is provided with a feeding belt and a discharging belt for loading and unloading masks, respectively. The base 1 is integrally connected with a support plate 2 for placing masks. The support plate 2 is horizontally arranged between the feeding belt and the discharging belt. The feeding belt can realize intermittent discharging of masks, and the discharging belt can convey the processed masks.

[0031] The support plate 2 is integrally connected with a feed plate 3 corresponding to the feed belt and used to transport the masks. Figure 2 As shown, the blanking plate 3 is tilted and can transport the mask to the support plate 2. The support plate 2 is provided with a blanking port 4 corresponding to the blanking plate 3. The support plate 2 is movably provided with a clamping plate 10 that is symmetrically arranged and limits the position of the mask;

[0032] The sliding sleeve in the support plate 2 is provided with a symmetrically arranged moving end 8, and two clamping plates 10 are arranged on the moving end 8, and the clamping plate 10 is an L-shaped structure adapted to the mask. By setting the clamping plate 10 as an L-shaped structure adapted to the mask, not only can the contact area between the clamping plate 10 and the mask be increased, but also the structure of the clamping plate 10 can straighten the mask when moving toward each other, and a moving component for driving the two moving ends 8 to move horizontally is installed on the base 1;

[0033] The moving assembly includes a motor 5 fixedly mounted on the base 1, and a bidirectional screw 6 is fixedly connected to the output end of the motor 5, two matching nuts 7 are slidably sleeved on the bidirectional screw 6, and a moving end 8 is arranged on the nut 7. The bidirectional screw 6 is arranged horizontally, and a cavity 9 for guiding the moving end 8 is opened on the support plate 2. The cavity 9 guides the moving end 8, thereby limiting the moving direction of the nut 7;

[0034] When the mask falls onto the support plate 2, the motor 5 is powered on and drives the bidirectional screw 6 to rotate. The bidirectional screw 6 drives the two nuts 7 to move toward each other during rotation. The nuts 7 drive the moving end 8 and the clamping plate 10 to gradually approach the mask, so that the clamping plate 10 clamps the mask from both sides. The mask is straightened by the clamping plate 10, which can increase the contact degree between the sealing end and the mask.

[0035] A telescopic rod 11 is fixedly installed in the support plate 2, and a contact plate 12 that resists the movement of the mask is fixedly connected to the output end of the telescopic rod 11. When the mask is processed, the output end of the telescopic rod 11 is extended and drives the contact plate 12 to slide on the support plate 2, so that the contact plate 12 can resist the mask, and then the mask can fall onto the unloading belt through the unloading port 4 for transportation;

[0036] A limiting component for limiting the position of the ear hook rope is installed on the support plate 2;

[0037] The limit assembly includes a bracket 13 fixedly mounted on the support plate 2, and a fixed end 18 is connected to the bracket 13 through a lifting member, a notch for placing the ear hook rope is provided in the fixed end 18, a sliding sleeve is provided in the fixed end 18 with a symmetrically arranged card plate 20 that is movably opposed to the ear hook rope, and a second spring 19 is welded between the card plate 20 and the fixed end 18, the card plate 20 is a plate-like structure with a raised side, the second spring 19 is horizontally welded, and the second spring 19 realizes the reset function of the card plate 20. When the card plate 20 is in a state of no force, the second spring 19 can drive the card plate 20 back to the initial position;

[0038] The lifting member includes a guide rod 14 fixedly mounted on the bracket 13, and a guide block 15 is slidably sleeved on the guide rod 14, and a clamp plate 23 for clamping the guide block 15 is fixedly mounted on the support plate 2. The guide rod 14 guides the guide block 15, so that the guide block 15 can smoothly pull the moving plate 17 when moving. By arranging the clamp plate 23 on the support plate 2, the clamp plate 23 can intercept the guide block 15 moving downward. It is supplemented that when the clamp plate 23 intercepts the guide block 15 moving downward, the ear hook rope on the fixed end 18 can correspond to the mask;

[0039] A spring 16 that matches the guide rod 14 is welded between the guide block 15 and the bracket 13. A symmetrically arranged moving plate 17 is fixedly mounted on the guide block 15. The fixed end 18 is arranged on the moving plate 17. The spring 16 has a buffering effect on the guide block 15, so that the guide block 15 will not cause excessive impact on the bracket 13 when moving downward, thereby ensuring the stability of the fixed end 18 when moving;

[0040] The guide rod 14 is vertically arranged, the spring 16 is sleeved on the guide rod 14, and a frame 21 is integrally connected between the two guide blocks 15, and a telescopic rod 22 connected to the frame 21 is fixedly installed on the base 1;

[0041] After the mask corners are heat-sealed, the operator manually pulls the ear hook rope so that the two ends of the ear hook rope can extend into the fixed end 18, and clamps the ear hook rope in the fixed end 18 through two clamping plates 20, so that the two ends of the ear hook rope can extend out of the fixed end 18, and the output end of the telescopic rod 22 is telescopic to drive the frame 21 to move downward, so that the frame 21 can drive the two guide blocks 15 to move downward, and the guide blocks 15 can drive the movable plate 17 and the fixed end 18 to move downward, and the position of the guide blocks 15 is locked by the guide rod 14, so that the fixed end 18 moves downward and drives the ear hook rope to extend onto the mask, and then the ear hook rope is heat-sealed on the mask through the sealing end, so that the position of the ear hook rope is always kept stable during the heat sealing, so that the ear hook rope does not need to be manually pulled during the heat sealing process, thereby ensuring the safety of the operator and ensuring the quality of the mask after overall processing;

[0042] The base 1 as a whole can perform heat-sealing processing on the mask layer and the ear hanging rope in sequence, which not only improves the efficiency of the heat-sealing processing of the mask, but also reduces the cost of the heat-sealing processing of the mask;

[0043] It should be noted that the specific models and specifications of the motor 5, telescopic rod 1 11, and telescopic rod 22 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it is not repeated here.

[0044] The present invention can be explained by the following operation mode:

[0045] After the feeding belt is powered on, it can intermittently transport the mask to the unloading plate 3, and the mask falls onto the support plate 2 through the unloading plate 3;

[0046] The output end of the motor 5 drives the bidirectional screw 6 to rotate, and the bidirectional screw 6 drives the two nuts 7 to move towards or in opposite directions when rotating;

[0047] When the two nuts 7 move toward each other, the movable end 8 is driven to slide in the cavity 9. When the movable end 8 moves, the two clamping plates 10 are driven to move toward each other, so that the clamping plates 10 can straighten and limit the mask.

[0048] After the sealing end is opened, the corners of the mask can be heat-sealed. After the corners of the mask are heat-sealed, the sealing end returns to the initial position;

[0049] At the same time, the operator pulls the two ends of the ear hook rope so that the two ends of the ear hook rope extend into the fixed end 18. When the ear hook rope extends into the fixed end 18, it can resist the card plate 20. The spring 2 19 is stressed to extend the ear hook rope into the notch, and pull the two ends of the ear hook rope so that the two ends of the ear hook rope can correspond to the mask.

[0050] The output end of the telescopic rod 22 is extended and retracted to drive the frame 21 to move downward, and the frame 21 drives the two guide blocks 15 to move downward when moving downward, and the spring 16 is compressed when the guide blocks 15 slide on the guide rod 14;

[0051] When the guide block 15 moves downward and extends onto the clamp plate 23, the fixed end 18 can drive the ear hook rope to extend onto the mask;

[0052] The sealing end is opened to heat-seal the ear loops on both ends of the mask;

[0053] When the ear hook is installed, the clamping plate 10 returns to the initial position, the ear hook is removed from the fixed end 18, and the output end of the telescopic rod 11 is extended to drive the contact plate 12 to move, so that the contact plate 12 applies pressure to the mask and the mask falls onto the discharge plate 3 through the discharge port 4;

[0054] Repeat the above steps so that the mask can intermittently fall onto the support plate 2 for heat sealing.

[0055] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
