Description

Technical Field

[0001] This invention relates to the field of embossing machine technology, and more particularly to a double-headed blanket embossing machine. Background Technology

[0002] A double-head embossing machine for blankets is a crucial piece of equipment specifically designed for the textile industry, particularly in blanket production. Its main function is to press various patterns and designs onto the blanket surface using hot pressing technology. The double-head design of this machine improves production efficiency and meets diverse market demands. With the continuous advancement of textile technology and the diversification of market needs, functional fabrics have gradually become a highlight in blanket products. Functional fabrics refer to textiles with special properties, such as waterproofing, breathability, UV resistance, antibacterial properties, and warmth retention. In blanket production, combining the hot pressing technology of a double-head embossing machine allows for the application of these functional fabrics on the blanket surface. Through the hot pressing process, functional coatings or films are embedded into the blanket fibers, resulting in an integrated performance enhancement.

[0003] The prior art publication number CN108374264A provides an automatic embossing machine for blankets. This technology has a reasonable structure, a high degree of automation, and can form a variety of embossed patterns in one step. The patterns have a strong three-dimensional effect, are not easy to recover from deformation, and have low production costs.

[0004] Existing embossed boards are mostly made of cast iron and fixed with bolts. A single board can weigh 50-200 kg, requiring manual handling with the assistance of overhead cranes and forklifts. However, current technology is not convenient for automatically replacing embossed boards, which makes them prone to shaking and slipping during handling, posing a risk of injuring operators. When manually aligning and positioning, operators need to enter the dangerous area under the machine head. If the equipment is accidentally started, it can easily cause crushing accidents. Loading and unloading heavy embossed boards increases the physical burden on operators, making replacement time-consuming and resulting in significant downtime losses.

[0005] In summary, the existing technology lacks a technique for auxiliary replacement of the embossing plate in a double-headed blanket embossing machine. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of the prior art by proposing a double-headed embossing machine for blankets.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a double-headed embossing machine for blankets, comprising a machine body, a base slidably fitted inside the machine body, a standing plate placed inside the base, a climbing mechanism rotatably connected below the standing plate, two support mechanisms symmetrically arranged on the base, a movable seat above the base, a top seat slidably fitted on the movable seat, an auxiliary plate changing mechanism slidably fitted on the top seat, two sets of hydraulic frames installed on the machine body, and embossing plates installed below the hydraulic frames.

[0008] Preferably, the inner wall of the base is threaded with a threaded rod, one end of which is rotatably connected to the inner wall of the machine body, and the outer end of the threaded rod is fixedly connected to a motor, which is fixedly connected to the outer wall of the machine body. The base has a placement groove, and the inner wall of the placement groove is slidably fitted with the outer wall of the station plate.

[0009] Preferably, a bidirectional lead screw is rotatably connected through the inner wall of the station plate, and an adjustment frame is threadedly connected to the outer wall of both ends of the bidirectional lead screw. A connecting rod is rotatably connected to both ends of the adjustment frame, and a plug-in support foot is rotatably connected to the other end of the connecting rod.

[0010] Preferably, the climbing mechanism includes a rotating frame, one end of which is rotatably connected to the inner wall of the station platform. A footboard is fixedly connected to the inner wall of the rotating frame in a linear structure. A worm gear is fixedly connected to the middle of one end of the rotating frame. A worm is meshed and driven on one side of the worm gear. The worm is rotatably connected to the inner wall of the station platform. A driven wheel is fixedly connected to one end of the worm. A driving wheel is fixedly connected to one end of the bidirectional lead screw. The driving wheel and the driven wheel are meshed and driven.

[0011] Preferably, the support mechanism includes a sliding frame, which is slidably fitted with the inner wall of the base. A contact rod is fixedly connected to one end of the sliding frame, and the other end of the contact rod extends to the outside of the base and is in movable contact with the inner wall of the machine. Two transmission racks are fixedly connected to both ends of the sliding frame in a centrally symmetrical structure.

[0012] Preferably, a transmission wheel is meshed on one side of the transmission rack, and a support rod assembly is fixedly connected to one end of the transmission wheel. The bottom end of the support rod assembly is rotatably connected to the inner wall of the base, and the top end of the support rod assembly is rotatably connected to the movable seat.

[0013] Preferably, the bottom of the movable seat is fixedly connected with multiple tension springs, the other end of which is fixedly connected to the base. The inner wall of the movable seat is symmetrically connected with two hydraulic rods, the output end of which is fixedly connected to the top seat.

[0014] Preferably, the auxiliary plate changing mechanism includes a plate changing seat, on which a positioning groove is provided. The inner wall of the positioning groove is adapted to the outer wall of the embossed plate. Two hydraulic rods are fixedly connected to the bottom inner wall of the plate changing seat, and the other end of each hydraulic rod is fixedly connected to a top seat.

[0015] Preferably, each of the four corners below the plate changing base is rotatably connected with a traveling wheel, and an electric push rod is fixedly connected to the traveling wheel. The other end of the electric push rod is fixedly connected to the plate changing base. The traveling wheel is in sliding contact with the machine body. The plate changing base has two symmetrical insertion holes at both ends, and the insertion holes are movably inserted into the insertion support feet.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. By setting up an auxiliary plate changing mechanism, and by opening a positioning groove on the plate changing seat that matches the shape of the embossed plate, when the embossed plate needs to be replaced, the plate changing seat can be automatically moved under the embossed plate to receive the disassembled embossed plate. At the same time, the replaced embossed plate can be automatically transferred to the hydraulic frame for installation. This allows the double-headed blanket embossing machine to automatically transport and receive the embossed plate when changing it, reducing manual intervention. This not only speeds up the plate changing speed but also reduces the complexity of operation and improves the overall efficiency of the production line. The automated plate changing mechanism can shorten the equipment downtime and avoid the long time required for manual plate changing, thereby increasing production capacity.

[0018] 2. By setting up a platform and climbing mechanism, when it is necessary to replace the embossed board, first move the board replacement base under the embossed board, then move out the plug-in support feet at the bottom of the platform, which will drive the climbing mechanism out. After the platform is placed above the board replacement base, the climbing mechanism will form a ladder, making it easier and safer for personnel to go up and down, preventing slips or falls. At the same time, the structure of the ladder can provide good support, making employees feel more secure. Meanwhile, the platform provides a flat and stable working surface, making it safer for operators to perform board replacement work on it, avoiding accidents caused by unstable standing posture. This can further improve the safety, efficiency and flexibility of the double-headed blanket embossing machine when replacing embossed boards.

[0019] 3. By setting up a movable base, top seat, and support mechanism, the auxiliary structure for changing embossing boards can be retracted into the machine body when it is not necessary to change the embossing boards. This saves a lot of external space, reduces the feeling of crowding in the factory or workshop, and facilitates daily operation. At the same time, by setting the wheels at the four corners of the board changing base, it provides stable support when moving on the machine body, making it easier to move heavier embossing boards. This not only improves the convenience and safety of the equipment, but also saves space and reduces the difficulty of maintenance and cleaning. Attached Figure Description

Detailed Implementation

[0029] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0030] like Figures 1-8The double-headed embossing machine for blankets shown includes a machine body 1, a base 2 slidably fitted inside the machine body 1, a standing plate 3 placed inside the base 2, a climbing mechanism 4 rotatably connected below the standing plate 3, two support mechanisms 5 symmetrically arranged on the base 2, a movable seat 6 above the base 2, a top seat 7 slidably fitted on the movable seat 6, an auxiliary plate changing mechanism 8 slidably fitted on the top seat 7, two sets of hydraulic frames 9 installed on the machine body 1, and an embossing plate 10 installed below the hydraulic frames 9.

[0031] like Figure 3 As shown, a threaded rod 201 is threadedly connected to the inner wall of the base 2. One end of the threaded rod 201 is rotatably connected to the inner wall of the machine body 1. A motor 202 is fixedly connected to the outer end of the threaded rod 201. The motor 202 is fixedly connected to the outer wall of the machine body 1. A placement groove 203 is opened in the base 2. The inner wall of the placement groove 203 is slidably fitted with the outer wall of the station plate 3.

[0032] The motor 202 is a servo motor with stable speed. The rotation angle can be precisely controlled by pulse signals, thereby controlling the moving speed and position of the base 2. The size of the placement slot 203 is precisely matched with the station plate 3, which can ensure that the station plate 3 is placed stably and avoids shaking, while also facilitating the quick removal and storage of the station plate 3.

[0033] like Figure 4 As shown, a bidirectional screw 301 is rotatably connected through the inner wall of the station plate 3. An adjusting frame 302 is threadedly connected to the outer wall of both ends of the bidirectional screw 301. A connecting rod 303 is rotatably connected to both ends of the adjusting frame 302. A plug-in support leg 304 is rotatably connected to the other end of the connecting rod 303.

[0034] The bottom of the plug-in support leg 304 is equipped with an anti-slip rubber pad to increase the friction with the plate changing seat 801 and ensure that the station plate 3 is placed stably. It is linked with the adjustment frame 302 through the connecting rod 303, which can realize the rapid extension and retraction of the plug-in support leg 304.

[0035] like Figure 5 As shown, the climbing mechanism 4 includes a rotating frame 401. One end of the rotating frame 401 is rotatably connected to the inner wall of the station plate 3. A pedal 402 is fixedly connected to the inner wall of the rotating frame 401 in a linear structure. A worm gear 403 is fixedly connected to the middle of one end of the rotating frame 401. A worm 404 is meshed and driven on one side of the worm gear 403. The worm 404 is rotatably connected to the inner wall of the station plate 3. A driven wheel 405 is fixedly connected to one end of the worm 404. A driving wheel 305 is fixedly connected to one end of the bidirectional lead screw 301. The driving wheel 305 and the driven wheel 405 are meshed and driven.

[0036] The rotating frame 401 is made of aluminum alloy, which is lightweight and rigid. The footboard 402 makes it easy for people to get on and off. The worm gear 403 and worm 404 provide smooth transmission and have a self-locking function, which can keep the climbing mechanism 4 stably at the unfolded angle and prevent accidental retraction. The transmission between the drive wheel 305 and the driven wheel 405 ensures that when the bidirectional screw 301 rotates, the climbing mechanism 4 and the plug-in support leg 304 move in sync, simplifying the operation steps.

[0037] like Figure 6 As shown, the support mechanism 5 includes a sliding frame 501, which is slidably fitted with the inner wall of the base 2. One end of the sliding frame 501 is fixedly connected to a contact rod 502, and the other end of the contact rod 502 extends to the outside of the base 2 and is in movable contact with the inner wall of the body 1. Two transmission racks 503 are fixedly connected at both ends of the sliding frame 501 in a centrally symmetrical structure.

[0038] The sliding frame 501 is made of stainless steel, and the tooth surface of the transmission rack 503 is carburized and quenched, resulting in high hardness and strong wear resistance. The meshing transmission ratio with the transmission wheel 504 is precise, which can smoothly convert the linear motion of the sliding frame 501 into the rotational motion of the strut assembly 505.

[0039] A transmission rack 503 is equipped with a transmission wheel 504 on one side for meshing transmission. A support rod assembly 505 is fixedly connected to one end of the transmission wheel 504. The bottom end of the support rod assembly 505 is rotatably connected to the inner wall of the base 2, and the top end of the support rod assembly 505 is rotatably connected to the movable seat 6.

[0040] The strut assembly 505 is made of high-strength alloy steel, which can form a stable support structure and improve the load-bearing capacity of the movable seat 6. Wear-resistant bushings are provided at the rotating connection between the strut assembly 505 and the movable seat 6 and the base 2 to extend the service life.

[0041] like Figure 7 As shown, multiple tension springs 601 are fixedly connected to the bottom of the movable seat 6, and the other end of the tension spring 601 is fixedly connected to the base 2. Two hydraulic rods 602 are fixedly connected to the inner wall of the movable seat 6 in a symmetrical structure, and the output end of the hydraulic rods 602 is fixedly connected to the top seat 7.

[0042] The tension spring 601 is a stainless steel compression spring, which drives the movable seat 6 to return smoothly to its original position when the support mechanism 5 retracts.

[0043] like Figure 8 As shown, the auxiliary plate changing mechanism 8 includes a plate changing base 801, on which a positioning groove 802 is provided. The inner wall of the positioning groove 802 is adapted to the outer wall of the embossed plate 10. Two hydraulic rods 803 are fixedly connected to the bottom inner wall of the plate changing base 801, and the other end of the hydraulic rods 803 is fixedly connected to the top seat 7.

[0044] The plate changing base 801 is made of high-strength aluminum alloy and has sufficient load-bearing capacity to support the weight of a single embossed plate 10. The inner wall of the positioning groove 802 is equipped with an elastic rubber pad to prevent the embossed plate 10 from being bumped or damaged when placed. It is precisely matched with the embossed plate 10 to ensure that the embossed plate 10 is placed stably.

[0045] The plate changing base 801 is rotatably connected to four corners below, and electric push rods 806 are fixedly connected to the walking wheels 804. The other end of the electric push rods 806 is fixedly connected to the plate changing base 801. The walking wheels 804 are in sliding contact with the machine body 1. The plate changing base 801 has two symmetrical insertion holes 805 at both ends, and the insertion holes 805 are movably inserted into the insertion feet 304.

[0046] The walking wheels 804 are made of polyurethane, which has good wear resistance and shock absorption, allowing the plate changing base 801 to move smoothly on the machine body 1 with low movement resistance; the electric push rod 806 can adjust the height of the walking wheels 804 to achieve stable support and movement switching of the plate changing base 801.

[0047] By setting up an auxiliary plate changing mechanism 8, and by opening a positioning groove 802 on the plate changing base 801 that matches the shape of the embossed plate 10, when the embossed plate 10 needs to be replaced, the plate changing base 801 can be automatically moved under the embossed plate 10 to receive the disassembled embossed plate 10. At the same time, the replaced embossed plate 10 can be automatically transferred to the hydraulic frame 9 for installation. This allows the double-headed blanket embossing machine to automatically transport and receive the embossed plate 10 when changing it, reducing manual intervention. This not only speeds up the plate changing speed but also reduces the complexity of operation and improves the overall efficiency of the production line. The automated plate changing mechanism can shorten the equipment downtime and avoid the long time required for manual plate changing, thereby increasing production capacity.

[0048] Working principle: After the equipment is started, the two sets of hydraulic frames 9 drive the embossing plates 10 to the initial high position. The blanket is fed into the machine body 1 through the conveying mechanism, passing synchronously under the two sets of embossing plates 10. The hydraulic frames 9 start, driving the embossing plates 10 to move downwards, performing synchronous embossing on the blanket. After embossing is completed, the hydraulic frames 9 drive the embossing plates 10 to reset, and the blanket continues to be conveyed, completing continuous embossing production. During this process, the auxiliary plate changing mechanism 8, the station plate 3, the climbing mechanism 4, and other components are all housed inside the machine body 1: the base 2 is located inside the machine body 1, the strut group 505 of the support mechanism 5 retracts, the moving seat 6 descends to the low position, the top seat 7 retracts above the moving seat 6, the plate changing seat 801 is housed above the top seat 7, the station plate 3 is placed in the placement slot 203 of the base 2, and the climbing mechanism 4 is folded and housed under the station plate 3, saving external space and not affecting normal production operations.

[0049] When it is necessary to replace the embossed plate 10, first stop the blanket conveying, and the hydraulic frame 9 will lift the embossed plate 10 to the high position and lock it; start the motor 202, which will drive the threaded rod 201 to rotate. The threaded rod 201 will drive the base 2 to slide outward along the inner wall of the machine body 1 until the base 2 moves to the outside, at which point the motor 202 will stop; during the movement of the base 2, the contact rod 502 at one end of the sliding frame 501 will contact and move with the inner wall of the machine body 1, causing the connected sliding frame 501 to slide along the inner wall of the base 2, driving the transmission rack 503 to move. The transmission rack 503 will mesh with the transmission wheel 504 to transmit power. The mechanism is activated, driving the strut assembly 505 to unfold, which pushes the movable seat 6 upward to a preset height. Hydraulic rod 602 is then activated, driving the top seat 7 to slide horizontally along the movable seat 6, thus moving the auxiliary plate changing mechanism 8 to one side of one set of embossed plates 10. Then, hydraulic rod 803 is activated, driving the plate changing seat 801 to move below one set of embossed plates 10. The electric actuator 806 then drives the traveling wheel 804 to contact the machine body 1, providing support and aligning the positioning groove 802 with the embossed plate 10, ready to receive the embossed plate 10.

[0050] Then, the operator takes out the station plate 3 from the placement slot 203 of the base 2, rotates the bidirectional lead screw 301 on the station plate 3, and drives the adjusting frames 302 at both ends to move outward synchronously. The adjusting frames 302 drive the plug-in support legs 304 to extend outward through the connecting rod 303. At the same time, the driving wheel 305 at one end of the bidirectional lead screw 301 meshes with the driven wheel 405 at one end of the worm gear 404, driving the worm gear 404 to rotate. The worm gear 404 meshes with the worm wheel 403, driving the rotating frame 401 to rotate outward and unfold, forming a climbing ladder. The station plate 3 is placed above the plate changing seat 801, so that the plug-in support legs 304 are inserted into the plug-in holes 805 of the plate changing seat 801, completing the fixing of the station plate 3. The operator climbs onto the station plate 3 through the step 402 of the climbing mechanism 4, ready to carry out the disassembly of the embossed board 10.

[0051] Then, the operator removes the connecting bolts between the hydraulic frame 9 and the embossed plate 10 on the station plate 3. After disassembly, the embossed plate 10 is placed stably in the positioning groove 802 of the plate changing seat 801. The elastic rubber pad in the positioning groove 802 provides cushioning protection for the embossed plate 10. The second hydraulic rod 803 is activated to drive the plate changing seat 801 to reset. During this process, the electric push rod 806 is controlled to drive the walking wheels 804 to retract sequentially. The first hydraulic rod 602 is activated to drive the top seat 7 to move the plate changing seat 801 and the old embossed plate 10 to the preset position outside the machine body 1. The old embossed plate 10 is then removed, and the new embossed plate 10 is placed on the plate changing seat 801 and transported to the bottom of the hydraulic frame 9. The operator completes the installation and fixing of the new embossed plate 10. After installation, the bidirectional screw 301 is rotated in the opposite direction to retract the plug-in support leg 304 and the climbing mechanism 4, and the station plate 3 is placed back into the placement groove 203 of the base 2.

[0052] After the new embossing board 10 is installed, following the reverse steps of the board replacement preparation stage, the top seat 7 and the moving seat 6 are driven to reset in sequence, and the motor 202 is started to rotate in the reverse direction, driving the base 2 to slide inward along the inner wall of the machine body 1. At this time, the contact rod 502 is unrestricted and can drive the moving seat 6 to move down and reset under the action of the tension spring 601, storing the auxiliary board replacement mechanism 8, the station plate 3 and other components inside the machine body 1. Then, the board replacement process is repeated to complete the replacement of another set of embossing boards 10. After both sets of embossing boards 10 are replaced, the equipment returns to the normal embossing operation state and continues to produce blanket embossing.
