Description

Technical Field

[0001] This utility model relates to the field of mattress assembly technology, and more specifically to a positioning device for assembling spring mattresses. Background Technology

[0002] A mattress, placed between the body and the bed, is designed to ensure a healthy and comfortable sleep experience for consumers. They come in a wide variety of materials, types, and styles, with spring mattresses, palm fiber mattresses, water mattresses, air mattresses, and magnetic mattresses being the most common. Assembly is a crucial step in the mattress manufacturing process.

[0003] A search revealed that patent application CN220296958U discloses a positioning device for assembling spring mattresses. While this device allows the bottom connecting plate to move left and right to adjust the distance depending on the size of the mattress or its installation position, thus moving the clamping base, the mattress is typically placed on two frames for support during assembly. The middle section of the mattress lacks support and is prone to collapsing under its own weight, affecting the assembly result. Furthermore, the device only limits the four corners of the mattress during assembly, neglecting to limit the top surface of the mattress's transmission mechanism. This allows the mattress to move up and down during assembly, impacting processing quality. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a positioning device for assembling spring mattresses, thus solving the problems mentioned in the background art.

[0005] The solution to the above-mentioned technical problems provided by this utility model is as follows:

[0006] A positioning device for assembling a spring mattress includes a support plate, a slide rail and a drive motor mounted on the top surface of the support plate, a first processing panel and a second processing panel provided on the support plate, and a spring mattress body placed on the first processing panel and the second processing panel.

[0007] The output shaft of the drive motor is equipped with a bidirectional lead screw;

[0008] The bottom surfaces of the first processing panel and the second processing panel are both equipped with guide frames and guide blocks. The first processing panel is equipped with a first support plate, and the second processing panel is equipped with a second support plate. Both the first processing panel and the second processing panel are provided with limit frames. The limit frames are equipped with a first hydraulic rod through an L-shaped bracket, and the bottom surface of the limit frames is equipped with a first limit wheel.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, a support frame is fixed to the bottom end face of the bearing plate, and a base is fixed to the bottom end face of the support frame.

[0011] The beneficial effects of adopting the above-mentioned further solutions are:

[0012] The support frame and the base together form a stable support structure, which can support and install the load-bearing plate.

[0013] Furthermore, the guide frame is slidably sleeved on the slide rail, and the guide block is threaded onto the bidirectional lead screw.

[0014] The beneficial effects of adopting the above-mentioned further solutions are:

[0015] When the drive motor starts, its output shaft drives the bidirectional lead screw to rotate. Since the guide block is connected to the bidirectional lead screw via a thread, according to the principle of threaded transmission, the guide block moves along the axial direction of the bidirectional lead screw. The guide frame slides onto the slide rail, providing excellent guidance and restricting the movement of the first and second processing panels to only along the slide rail, preventing offset or wobbling during movement. This design allows for precise control of the distance between the first and second processing panels to accommodate the assembly requirements of spring mattresses of different sizes, improving the versatility and flexibility of the positioning device.

[0016] Furthermore, there are four limiting frames in total, and the four limiting frames are equidistantly and symmetrically distributed relative to the first processing panel and the second processing panel.

[0017] The beneficial effects of adopting the above-mentioned further solutions are:

[0018] The four symmetrically distributed limiting frames can limit the four corners of the spring mattress body. During the mattress assembly process, when the mattress is under force, the first limiting wheel on the limiting frame can block and restrain it, effectively preventing the mattress from shifting on the processing panel.

[0019] Furthermore, a second limiting wheel is installed on the output shaft of the first hydraulic rod. The second limiting wheel limits the top surface of the spring mattress body, and the first limiting wheel limits both ends of the spring mattress body.

[0020] The beneficial effects of adopting the above-mentioned further solutions are:

[0021] The second limiting wheel, via the first hydraulic rod, can flexibly adjust the pressure on the top surface of the spring mattress body. During mattress assembly, the extension length of the first hydraulic rod can be precisely controlled according to factors such as the mattress material and thickness, ensuring that the second limiting wheel fits tightly against the top surface of the mattress, preventing the mattress from bouncing or moving upwards. The limiting effect of the first limiting wheel on both ends of the mattress, in conjunction with the second limiting wheel, provides comprehensive restraint from different positions, ensuring the mattress remains stable throughout the assembly process. This effectively avoids assembly errors caused by mattress position changes and improves assembly quality.

[0022] Furthermore, the second child support plate is slidably sleeved inside the first support plate, and the second child support plate and the first support plate support the spring mattress body.

[0023] The beneficial effects of adopting the above-mentioned further solutions are:

[0024] The sliding connection design between the second spring support plate and the first support plate allows the support structure to be adjusted according to different lengths of the spring mattress body. In actual assembly, for mattresses of various sizes, the extension length of the second spring support plate within the first support plate can be adjusted by moving the first and second processing panels, ensuring that both provide even and stable support to the mattress. This adjustable support method not only adapts to diverse mattress size requirements but also effectively distributes the mattress's own weight and external forces during assembly, preventing deformation due to excessive localized stress and preventing the mattress from collapsing inwards due to its own weight, thus ensuring the integrity and stability of the spring mattress body during assembly.

[0025] Furthermore, a second hydraulic rod is installed on the bottom end face of both the first processing panel and the second processing panel. A connecting frame is provided on the output shaft of the second hydraulic rod, and the top end face of the connecting frame is installed on the bottom end face of the limiting frame.

[0026] The beneficial effects of adopting the above-mentioned further solutions are:

[0027] The second hydraulic rod can precisely adjust the position of the limiting frame by controlling the extension and retraction of its output shaft. When assembling spring mattress bodies of different widths, the second hydraulic rod can be used to drive the limiting frame to move back and forth as needed, so that the first and second limiting wheels can accurately contact the corresponding positions on the mattress and perform their limiting function. This adjustable-width limiting frame design greatly enhances the adaptability of the positioning device to mattresses of different sizes, further improving the practicality and versatility of the positioning device in the spring mattress assembly process.

[0028] This utility model provides a positioning device for assembling spring mattresses. It has the following beneficial effects:

[0029] By driving a motor to rotate a bidirectional lead screw, and utilizing the threaded connection between the guide block and the bidirectional lead screw, as well as the sliding guidance of the guide frame on the slide rail, the distance between the first and second processing panels can be precisely controlled. This precise distance control can adapt to the assembly requirements of spring mattress bodies of different sizes, improving the versatility and flexibility of the positioning device and meeting diverse production requirements.

[0030] Four symmetrically distributed positioning brackets can limit the four corners of the spring mattress body, effectively preventing the mattress from shifting during assembly. Simultaneously, the first positioning wheel limits both ends of the mattress, while the second positioning wheel, via the first hydraulic rod, flexibly adjusts the pressure on the top surface of the mattress, providing comprehensive positioning from different positions. This ensures the mattress remains stable throughout the assembly process, avoiding assembly errors caused by mattress position changes and improving assembly quality.

[0031] The second spring support plate slides within the first support plate and can be adjusted to accommodate different lengths of the spring mattress body. During assembly, the extension length of the second spring support plate within the first support plate can be adjusted by moving the first and second processing panels, according to the mattress specifications, providing even and stable support for the mattress. This adjustable support method not only adapts to diverse mattress size requirements but also effectively distributes the mattress's weight and external forces, preventing deformation or sagging and ensuring the mattress's integrity and stability during assembly.

[0032] The position of the limiting frame is controlled by a second hydraulic rod. When assembling spring mattress bodies of different widths, the limiting frame can be driven to move back and forth as needed, ensuring that the first and second limiting wheels accurately contact the corresponding positions on the mattress and perform their limiting function. This adjustable-width limiting frame design enhances the adaptability of the positioning device to mattresses of different sizes, further improving the practicality and versatility of the positioning device in the spring mattress assembly process.

[0041] 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.

[0042] Please see Figures 1 to 4 As shown, the embodiments provided by this utility model are as follows:

[0043] Example 1

[0044] The positioning device for assembling a spring mattress includes a support plate 1, a slide rail 103 and a drive motor 105 mounted on the top surface of the support plate 1, a first processing panel 2 and a second processing panel 203 provided on the support plate 1, and a spring mattress body 106 placed on the first processing panel 2 and the second processing panel 203.

[0045] A bidirectional lead screw 104 is provided on the output shaft of the drive motor 105;

[0046] Guide frames 201 and guide blocks 202 are installed on the bottom surfaces of the first processing panel 2 and the second processing panel 203. A first support plate 204 is installed on the first processing panel 2, and a second support plate 205 is installed on the second processing panel 203. A limit frame 302 is provided on both the first processing panel 2 and the second processing panel 203. A first hydraulic rod 301 is installed on the limit frame 302 through an L-shaped bracket 3. A first limit wheel 303 is installed on the bottom surface of the limit frame 302.

[0047] A support frame 101 is fixed to the bottom end face of the bearing plate 1, and a base 102 is fixed to the bottom end face of the support frame 101. The support frame 101 and the base 102 together form a stable support structure, which can support and install the bearing plate 1.

[0048] The guide frame 201 is slidably sleeved on the slide rail 103, and the guide block 202 is threadedly mounted on the double-acting lead screw 104. When the drive motor 105 starts, its output shaft drives the double-acting lead screw 104 to rotate. Since the guide block 202 is threadedly connected to the double-acting lead screw 104, according to the principle of threaded transmission, the guide block 202 will move along the axial direction of the double-acting lead screw 104. The guide frame 201, slidably sleeved on the slide rail 103, plays a good guiding role, restricting the first processing panel 2 and the second processing panel 203 to move only along the direction of the slide rail 103, avoiding deviation or shaking during movement. This design can precisely control the distance between the first processing panel 2 and the second processing panel 203 to adapt to the assembly requirements of spring mattress bodies 106 of different sizes, improving the versatility and flexibility of the positioning device.

[0049] The second spring mattress support plate 205 is slidably sleeved within the first support plate 204. The second spring mattress support plate 205 and the first support plate 204 support the spring mattress body 106. This sliding sleeve design allows the support structure to be adjusted according to different lengths of the spring mattress body 106. In actual assembly, for mattresses of various sizes, the extension length of the second spring mattress support plate 205 within the first support plate 204 can be adjusted by moving the first processing panel 2 and the second processing panel 203, ensuring that both provide uniform and stable support for the mattress. This adjustable support method not only adapts to diverse mattress size requirements but also effectively distributes the mattress's own weight and external forces during assembly, preventing deformation due to excessive localized stress and preventing the mattress from collapsing inwards due to its own weight, thus ensuring the integrity and stability of the spring mattress body 106 during assembly.

[0050] Example 2

[0051] To simultaneously support and limit the four corners and top surface of the mattress, preventing displacement during assembly and affecting processing, for example, such as... Figures 1 to 4 As shown, this utility model also includes:

[0052] There are four limiting frames 302 in total, and the four limiting frames 302 are equidistantly and symmetrically distributed relative to the first processing panel 2 and the second processing panel 203. The four equidistantly and symmetrically distributed limiting frames 302 can limit the four corners of the spring mattress body 106. During the mattress assembly process, when the mattress is subjected to force, the first limiting wheels 303 on the limiting frames 302 can block and restrain it, effectively preventing the mattress from shifting on the processing panel.

[0053] A second limiting wheel 304 is mounted on the output shaft of the first hydraulic rod 301. The second limiting wheel 304 limits the top surface of the spring mattress body 106, while the first limiting wheel 303 limits both ends of the spring mattress body 106. The second limiting wheel 304 can flexibly adjust the pressure on the top surface of the spring mattress body 106 via the first hydraulic rod 301. During mattress assembly, the extension length of the first hydraulic rod 301 can be precisely controlled according to factors such as the mattress material and thickness, ensuring that the second limiting wheel 304 can tightly fit the top surface of the mattress, preventing the mattress from bouncing or moving upwards. The limiting effect of the first limiting wheel 303 on both ends of the mattress, in conjunction with the second limiting wheel 304, provides all-around limiting of the mattress from different positions, ensuring that the mattress remains stable throughout the assembly process. This effectively avoids assembly errors caused by mattress position changes and improves assembly quality.

[0054] A second hydraulic rod 305 is mounted on the bottom surface of both the first processing panel 2 and the second processing panel 203. A connecting frame 306 is mounted on the output shaft of the second hydraulic rod 305, and the top surface of the connecting frame 306 is mounted on the bottom surface of the limiting frame 302. The second hydraulic rod 305 can precisely adjust the position of the limiting frame 302 by controlling the extension and retraction of its output shaft. When assembling spring mattress bodies 106 of different widths, the limiting frame 302 can be driven to move back and forth using the second hydraulic rod 305 as needed, so that the first limiting wheel 303 and the second limiting wheel 304 can accurately contact the corresponding positions on the mattress and perform their limiting function. This adjustable-width limiting frame 302 design greatly enhances the adaptability of the positioning device to mattresses of different sizes, further improving the practicality and versatility of the positioning device in the spring mattress assembly process.

[0055] Working principle:

[0056] Panel Position Adjustment: The drive motor 105 starts, and its output shaft drives the bidirectional lead screw 104 to rotate. Since the guide block 202 is threaded onto the bidirectional lead screw 104, according to the principle of threaded transmission, the guide block 202 will move along the axial direction of the bidirectional lead screw 104. At the same time, the guide frame 201 is slidably sleeved on the slide rail 103, playing a guiding role and restricting the first processing panel 2 and the second processing panel 203 to move only along the direction of the slide rail 103, thereby precisely controlling the distance between the first processing panel 2 and the second processing panel 203 to adapt to the assembly requirements of spring mattress bodies 106 of different sizes.

[0057] Mattress Placement and Corner Restraint: The spring mattress body 106 is placed on the first processing panel 2 and the second processing panel 203. Four restraint frames 302, which are equidistantly and symmetrically distributed relative to the first processing panel 2 and the second processing panel 203, restrain the four corners of the spring mattress body 106 through the first restraint wheels 303 on them, preventing the mattress from shifting on the processing panels.

[0058] Mattress Top Surface Limiting: A second limiting wheel 304 is installed on the output shaft of the first hydraulic rod 301. The extension length of the first hydraulic rod 301 can be precisely controlled according to factors such as the material and thickness of the spring mattress body 106, ensuring that the second limiting wheel 304 fits tightly against the top surface of the mattress to limit it and prevent the mattress from bouncing or moving upwards. In conjunction with the first limiting wheel 303, it provides omnidirectional limiting of the mattress from different positions, ensuring the mattress remains stable during assembly.

[0059] Mattress support adjustment: The second child support plate 205 is slidably sleeved inside the first support plate 204. When the first processing panel 2 and the second processing panel 203 move, the extension length of the second child support plate 205 inside the first support plate 204 can be adjusted according to the different lengths of the spring mattress body 106, so that the two together provide uniform and stable support for the mattress, preventing the mattress from deforming due to excessive local stress and collapsing in the middle due to its own weight.

[0060] Width adjustment of the limiting frame 302: When it is necessary to assemble spring mattress bodies 106 of different widths, the second hydraulic rod 305 controls the extension and retraction of its output shaft, drives the connecting frame 306 to move, thereby precisely adjusting the position of the limiting frame 302, so that the first limiting wheel 303 and the second limiting wheel 304 can accurately contact the corresponding position of the mattress and play a limiting role, enhancing the adaptability of the positioning device to mattresses of different specifications.
