Description

Technical Field

[0001] This utility model relates to the field of mattress rolling and packaging technology, specifically to an automatic mattress rolling and packaging device. Background Technology

[0002] A mattress is an item placed between the human body and a bed to ensure that consumers get healthy and comfortable sleep. There are many types of mattress materials, and mattresses made of different materials can bring different sleep effects. After the mattress is manufactured, it is large in size and not easy to transport, so it needs to be compressed and rolled up.

[0003] Currently, when packaging mattresses, they are first wrapped in plastic film, then transported to a vacuum compressor for compression and vacuuming to reduce their volume. After that, they are guided by a conveyor belt into a winding device for packaging. The winding device mainly uses a servo motor to drive the winding rollers. However, there is currently no anti-deviation structure when the conveyor belt is guided into the winding device, which makes it easy for the mattress to deviate during winding, causing the mattress to be unable to be rolled into a standard roll and thus unable to be stuffed into the packaging bag for packaging.

[0004] Therefore, it is of great importance to design an automatic mattress rolling and packaging device to solve the above-mentioned defects. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model designs an automatic mattress rolling and packaging device. This device aims to solve the technical problem that, in the existing technology, when rolling and packaging mattresses, no anti-displacement structure is set up, which makes it easy for the mattress to shift during rolling, causing the mattress to be unable to be rolled into a standard roll and stuffed into the packaging bag for packaging.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An automatic mattress rolling and packaging device includes a frame, a limit cover fixedly installed on the top of the frame, a first conveyor frame fixedly installed on the bottom of the top of the frame and inside the limit cover, an adjustment mechanism installed on the right end of the top of the frame, a second conveyor frame fixedly installed on the left side of the adjustment mechanism and above the first conveyor frame, a support frame fixedly installed on the back of the frame, a rolling assembly installed on the top of the support frame, and an auxiliary plate movably installed above the rolling assembly.

[0008] The adjustment mechanism includes a guide frame fixedly installed at the top right end of the frame. The front and rear ends of the right side of the second conveyor frame are slidably connected to the guide frame through sliding sleeves. A first lead screw is rotatably connected to the middle of the inner side of the guide frame. A first servo motor is fixedly installed on the top of the guide frame, and the drive end of the first servo motor is fixedly connected to the top end of the first lead screw. The right side of the second conveyor frame is connected to the first lead screw through a first lead screw nut.

[0009] As a preferred embodiment of this utility model, multiple sets of movable through slots are provided on both the left and right sides of the limiting cover, and a first guide frame is fixedly installed on the front of the limiting cover.

[0010] As a preferred embodiment of this utility model, both the left and right ends of the first conveyor frame are fixedly connected to the machine frame via first support rods, and auxiliary rollers are rotatably connected to the front and rear ends of the inner sides of the first and second conveyor frames.

[0011] As a preferred embodiment of this utility model, a second guide frame is fixedly installed at the front end of the support frame, and the left end of the second guide frame is fixedly connected to the support frame through a second support rod.

[0012] As a preferred embodiment of this utility model, the winding assembly includes a first slide block slidably connected inside the support frame, a hydraulic rod fixedly installed inside the support frame and below the first slide block, and the output end of the hydraulic rod fixedly connected to the bottom of the first slide block, a turntable rotatably connected to the left side of the first slide block, a second servo motor fixedly installed on the right side of the first slide block, and the drive end of the second servo motor fixedly connected to the turntable, a first winding rod fixedly connected to the left side of the turntable, and a second winding rod slidably connected to the left side of the turntable and below the first winding rod.

[0013] As a preferred embodiment of this utility model, the right end of the second winding rod is slidably connected to the turntable via a slider, a return spring is fixedly connected between the bottom of the slider and the turntable, and an electromagnet is fixedly installed at the left end of the support frame and below the second winding rod.

[0014] As a preferred embodiment of this utility model, the right end of the auxiliary plate is slidably connected to the support frame via a second slide block, the support frame is rotatably connected to a second lead screw, and the interior of the second slide block is connected to the second lead screw via a second lead screw nut. A third servo motor is fixedly installed on the top of the support frame, and the drive end of the third servo motor is fixedly connected to the top end of the second lead screw.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In this utility model, through the coordinated design of the limiting cover, the first conveyor frame, the second conveyor frame and the adjustment mechanism, when the mattress is rolled and packaged, the compressed mattress is inserted between the first conveyor frame and the second conveyor frame. The limiting cover limits both ends to prevent deviation. At the same time, the first servo motor is started to drive the first lead screw to rotate. Under the connection between the first lead screw nut and the sliding sleeve, the second conveyor frame moves downward. The second conveyor frame can limit the top of the compressed mattress according to its thickness, thereby stably guiding the mattress into the winding assembly for winding. This avoids deviation during the winding process, which can cause winding deviation, so that the mattress can be rolled into a standard roll for easy packaging.

[0017] 2. In this utility model, through the cooperative design of the winding assembly, the mattress is guided into the space between the first winding rod and the second winding rod via the second guide frame. The turntable is driven to rotate by the second servo motor to wind the mattress. When the mattress is guided into the space between the first winding rod and the second winding rod, one end of the mattress can be clamped, while the other end is limited, which further ensures the stability of the winding and effectively avoids the deviation that occurs during the winding process, so that the mattress can be wound into a standard roll for easy packaging.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Example: Please refer to Figures 1-5 This utility model provides a technical solution:

[0026] An automatic mattress rewinding and packaging device includes a frame 1, a limit cover 2 fixedly installed on the top of the frame 1, a first conveyor frame 3 fixedly installed on the bottom of the top of the frame 1 and inside the limit cover 2, an adjustment mechanism 4 installed on the right end of the top of the frame 1, a second conveyor frame 5 fixedly installed on the left side of the adjustment mechanism 4 and above the first conveyor frame 3, a support frame 6 fixedly installed on the back of the frame 1, a rewinding assembly 7 installed on the top of the support frame 6, and an auxiliary plate 8 movably installed above the rewinding assembly 7.

[0027] First, in this embodiment, the specific structure of the adjustment mechanism 4 is as follows:

[0028] The adjustment mechanism 4 includes a guide frame 401 fixedly installed at the top right end of the frame 1. The front and rear ends of the right side of the second conveyor frame 5 are slidably connected to the guide frame 401 via sliding sleeves 402. A first lead screw 403 is rotatably connected to the middle of the inner side of the guide frame 401. A first servo motor 404 is fixedly installed on the top of the guide frame 401, and the drive end of the first servo motor 404 is fixedly connected to the top end of the first lead screw 403. The right side of the second conveyor frame 5 is connected to the first lead screw 403 via a first lead screw nut 405. When the mattress is rolled and packaged, the compressed... The mattress is inserted between the first conveyor frame 3 and the second conveyor frame 5. The limiting cover 2 limits both ends to prevent deviation. At the same time, the first servo motor 404 is started to drive the first lead screw 403 to rotate. Under the connection of the first lead screw nut 405 and the sliding sleeve 402, the second conveyor frame 5 is moved downward. The second conveyor frame 5 can limit the top of the mattress according to the thickness of the compressed mattress, so as to stably guide the mattress into the winding assembly 7 for winding. This avoids deviation during the winding process and makes the mattress roll into a standard roll for easy packaging.

[0029] Furthermore, multiple sets of movable slots 201 are provided on both the left and right sides of the limiting cover 2. A first guide frame 202 is fixedly installed on the front of the limiting cover 2. When the height of the second conveyor frame 5 is adjusted, movable slots 201 are provided at the corresponding positions on the left and right sides of the limiting cover 2 and the second conveyor frame 5, as well as at the connection between the second conveyor frame 5 and the adjustment mechanism 4, so that the second conveyor frame 5 can move up and down normally. At the same time, when the compressed mattress is inserted between the first conveyor frame 3 and the second conveyor frame 5, it is guided by the first guide frame 202 for easy insertion.

[0030] Then, both the left and right ends of the first conveyor frame 3 are fixedly connected to the frame 1 through the first support rod 301. The front and rear ends of the inner sides of the first conveyor frame 3 and the second conveyor frame 5 are rotatably connected with auxiliary rollers 302. The first conveyor frame 3 is installed and fixed on the top of the frame 1 through the first support rod 301. At the same time, when the first conveyor frame 3 and the second conveyor frame 5 convey the compressed mattress, the auxiliary rollers 302 on the inner side can make the conveyor belt fit as closely as possible to the mattress surface for stable conveying.

[0031] Furthermore, a second guide frame 601 is fixedly installed at the front end of the support frame 6. The left end of the second guide frame 601 is fixedly connected to the support frame 6 via the second support rod 602. After being limited by the limit cover 2, the first conveyor frame 3 and the second conveyor frame 5, the mattress is stably guided into the winding assembly 7 through the second guide frame 601 for winding operation.

[0032] The winding assembly 7 includes a first slide block 701 slidably connected inside the support frame 6. A hydraulic rod 702 is fixedly installed inside the support frame 6 and below the first slide block 701, and the output end of the hydraulic rod 702 is fixedly connected to the bottom of the first slide block 701. A turntable 703 is rotatably connected to the left side of the first slide block 701. A second servo motor 704 is fixedly installed on the right side of the first slide block 701, and the drive end of the second servo motor 704 is fixedly connected to the turntable 703. A first winding rod 705 is fixedly connected to the left side of the turntable 703, and a second winding rod 706 is slidably connected to the left side of the turntable 703 and below the first winding rod 705. The mattress is guided between the first winding rod 705 and the second winding rod 706 through the second guide frame 601, and the turntable 703 is rotated by the second servo motor 704 to wind it up.

[0033] Secondly, the right end of the second winding rod 706 is slidably connected to the turntable 703 via a slider 707. A return spring 708 is fixedly connected between the bottom of the slider 707 and the turntable 703. An electromagnet 709 is fixedly installed on the left end of the support frame 6, below the second winding rod 706. Before the mattress is guided between the first winding rod 705 and the second winding rod 706, the first slide block 701 is lowered via the hydraulic rod 702, causing the second winding rod 706 to move downwards closer to the electromagnet 709. The second winding rod 706 is a metal rod; after the electromagnet 709 is activated, it is attracted by magnetic force. The lower suction holds the second winding rod 706, allowing the first winding rod 705 and the second winding rod 706 to open for easy mattress insertion. After the front end of the mattress is inserted, the electromagnet 709 is turned off. Under the action of the return spring 708, the second winding rod 706 is reset and works with the first winding rod 705 to clamp one end of the mattress. Then, the turntable 703 is rotated to wind up the mattress. Because one end of the mattress is clamped and the other end is limited, the stability of the winding is further ensured, effectively avoiding deviation during the winding process. This allows the mattress to be finally rolled into a standard roll for easy packaging.

[0034] Finally, the right end of the auxiliary plate 8 is slidably connected to the support frame 6 via the second slide block 801. The support frame 6 is rotatably connected to the second lead screw 802, and the interior of the second slide block 801 is connected to the second lead screw 802 via the second lead screw nut 803. The top of the support frame 6 is fixedly installed with the third servo motor 804, and the drive end of the third servo motor 804 is fixedly connected to the top end of the second lead screw 802. When the mattress is about to finish rolling, the third servo motor 804 is activated to lower the second slide block 801 via the second lead screw nut 803, thereby lowering the auxiliary plate 8 to press down on the outer side of the rolled-up mattress to prevent it from unfolding, thus completing the automatic rolling of the mattress. Finally, simply put the packaging bag on the mattress and the auxiliary plate 8 together, and pull the mattress off from the first rolling rod 705 and the second rolling rod 706 from below to complete the packaging.

[0035] In this embodiment, the specific implementation scenario is as follows: When the mattress is being rolled and packaged, the compressed mattress is inserted between the first conveyor frame 3 and the second conveyor frame 5. The limiting cover 2 limits both ends to prevent deviation. At the same time, the first servo motor 404 is started to drive the first lead screw 403 to rotate. Under the connection of the first lead screw nut 405 and the sliding sleeve 402, the second conveyor frame 5 moves downward. The second conveyor frame 5 can limit the top of the compressed mattress according to its thickness, thereby stably guiding the mattress into the winding assembly 7. The mattress is guided between the first winding rod 705 and the second winding rod 706 via the second guide frame 601. The turntable 703 is rotated by the second servo motor 704 to perform the winding. Before guiding the mattress between the first winding rod 705 and the second winding rod 706, the first slide block 701 is lowered via the hydraulic rod 702, causing the second winding rod 706 to move downwards towards the electromagnet 709. The second winding rod 706 is a metal rod; after the electromagnet 709 is activated, it is magnetically attracted to the second winding rod 706. 6. This allows the first winding rod 705 and the second winding rod 706 to open, facilitating the introduction of the mattress. After the mattress is introduced to the front end, the electromagnet 709 is deactivated. Under the action of the return spring 708, the second winding rod 706 returns to its original position, working in conjunction with the first winding rod 705 to clamp one end of the mattress. Then, the turntable 703 is rotated to wind up the mattress. Because one end of the mattress is clamped and the other end is limited, the stability of the winding is further ensured. When the mattress is about to finish winding, the third servo motor 804 is activated, connected to the second lead screw nut 803. Lower the second slide 801, thereby lowering the auxiliary plate 8 to press down on the outer side of the rolled-up mattress to prevent it from unfolding, thus completing the automatic rolling of the mattress. Finally, simply put the packaging bag over the mattress and the auxiliary plate 8, and pull the mattress off the first rolling rod 705 and the second rolling rod 706 from below to complete the packaging. The whole operation process is simple and convenient. This utility model ensures the stability of the rolling process through its design, effectively avoiding the deviation that occurs during the rolling process, so that the mattress can be rolled into a standard roll for easy packaging.

[0036] 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.
