Description

Technical Field

[0001] This application relates to the field of mattress processing equipment technology, specifically an automatic mattress cover application device. Background Technology

[0002] Mattresses, as household necessities, typically require a protective cover or film cover before production, transportation, or sale to prevent soiling or scratching during subsequent processes. However, the traditional method of covering mattresses with protective covers is entirely manual. Due to the large size, weight, and soft texture of mattresses, this requires multiple workers to work together, first stretching the protective cover open and then laboriously tucking the mattress corner by corner into it. This process is not only extremely labor-intensive and inefficient, but also prone to tearing and damaging the protective cover due to uneven force, increasing production costs. To address these issues, some auxiliary covering devices have emerged on the market, such as those using expandable frames to stretch the mattress cover. However, most of these devices still require manual pushing of the mattress into the stretched pocket, resulting in low automation and limited labor-saving effects. Utility Model Content

[0003] The purpose of this invention is to provide an automatic mattress cover application device that solves the problems of low automation and limited labor-saving effect of existing application devices.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an automatic mattress cover application device, comprising an operating table, a gantry frame slidably connected to the upper end of the operating table, a linkage block fixedly connected to the bottom of the vertical part of the gantry frame, the linkage block penetrating the operating table and slidably connected to the operating table, a movable seat fixedly connected to the bottom of the linkage block, the top of the movable seat slidably connected to the bottom of the operating table, two fixed seats fixedly connected to the bottom edge of the operating table, a motor fixedly mounted on one of the fixed seats, a threaded shaft fixedly connected to the end of the output shaft of the motor, the end of the threaded shaft being connected to the other fixed seat via a bearing, a self-lubricating mechanism being provided inside the movable seat, support legs fixedly connected to the four corners of the bottom of the operating table, a base plate fixedly connected to the four support legs, and multiple protrusions fixedly connected to the upper end of the base plate, the multiple protrusions being distributed in a straight line along the length direction of the base plate.

[0005] Preferably, the inner top of the gantry frame is connected to two fixed rods, the ends of which are jointly fixedly connected to a frame. A cylinder is fixedly installed in the middle of the upper end of the frame. The telescopic shaft of the cylinder passes through the frame and is slidably connected to it. A linkage plate is fixedly connected to the end of the telescopic shaft and is slidably connected to the inner side of the frame. Two sleeve rods are fixedly connected to both the linkage plate and the side of the frame. After the mattress cover is placed on the four sleeve rods, the linkage plate is pulled upward by the cylinder. The linkage plate moves the two sleeve rods on it upward, thereby opening the mattress cover and making it easier to put on the mattress.

[0006] Preferably, guide blocks are fixedly connected to both the left and right sides of the linkage plate, and the guide blocks pass through the frame and are slidably connected to the frame. The guide blocks guide the lifting and lowering of the linkage plate.

A stop block is fixedly connected to the upper center of the operating platform, and the stop block is located between two circular arc pads. The posts and circular arc pads provide support for the mattress.

[0008] Preferably, the self-lubricating mechanism includes a slider and an oil-retaining sponge slidably connected inside the movable seat. The slider and the oil-retaining sponge are in contact with each other. A sliding pin is fixedly connected to the bottom of the slider, passing through the movable seat and slidably connected to it. The end of the sliding pin has an arcuate surface that abuts against the base plate. The position of the arcuate surface corresponds to the position of the protruding strip. An oil outlet hole is provided inside the movable seat, and the position of the oil outlet hole corresponds to the positions of the oil-retaining sponge and the threaded shaft. Through the self-lubricating mechanism, the threaded pair between the movable seat and the threaded shaft is automatically lubricated.

[0009] Preferably, a spring is sleeved on the outer side of the sliding pin, one end of the spring is fixedly connected to the slider, and the other end of the spring is fixedly connected to the inner surface of the movable seat. The spring force can be applied to the sliding pin through the slider, which has an auxiliary repositioning effect on the sliding pin.

[0010] Preferably, a sealing ring is embedded in the side of the slider, and the sealing ring is slidably connected to the inner surface of the movable base. The sealing ring increases the sealing performance between the slider and the movable base.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model, by setting up a liftable linkage plate and sleeve rod structure, and cooperating with cylinder drive, can automatically and quickly open the mattress cover and maintain a stable opening state, which significantly reduces the labor intensity of manual application and improves the efficiency of operation. It is especially suitable for mass production scenarios, effectively avoids mattress cover deformation or damage, and improves the quality and consistency of application.

[0013] 2. This utility model provides a self-lubricating mechanism within the moving seat used to drive the gantry frame. The self-lubricating mechanism utilizes the periodic contact between the sliding pin and the convex strip to achieve automatic oil supply, and continuously lubricates the threaded shaft through the oil storage sponge, thereby reducing wear and operating noise, extending equipment life, and lowering maintenance frequency and costs.

The end of the threaded shaft 61 is connected to the other fixed seat 5 through a bearing.

[0023] Please see Figures 1-5 Two fixed rods 11 are connected to the top inner side of the gantry frame 2. The ends of the two fixed rods 11 are jointly connected to a frame 12. A cylinder 13 is fixedly installed in the middle of the upper end of the frame 12. The telescopic shaft of the cylinder 13 passes through the frame 12 and is slidably connected to it. A linkage plate 14 is fixedly connected to the end of the telescopic shaft and is slidably connected to the inner side of the frame 12. Two sleeve rods 16 are fixedly connected to the sides of both the linkage plate 14 and the frame 12. After the mattress cover is placed on the four sleeve rods 16, the cylinder 13 pulls the linkage plate 14 upwards. The linkage plate 14 moves the two sleeve rods 16 upwards, opening the mattress cover and making it easier to put on the mattress. Guide blocks 15 are fixedly connected to both the left and right sides of the linkage plate 14, passing through the frame 12 and slidably connected to it. The guide block 15 guides the lifting and lowering of the linkage plate 14. Two four-post structures 17 are fixed to the upper center of the operating platform 1. A circular arc pad 18 is fixedly connected to the top of two adjacent posts 17. A stop block 19 is fixedly connected to the upper center of the operating platform 1, positioned between two circular arc pads 18. The posts 17 and the circular arc pads 18 provide support for the mattress.

[0024] Please see Figures 5-6The movable seat 4 is equipped with a self-lubricating mechanism 7. Support legs 8 are fixedly connected to the four corners of the bottom of the operating platform 1. A base plate 9 is fixedly connected to the four support legs 8. Multiple protrusions 10 are fixedly connected to the upper end of the base plate 9, and these protrusions 10 are arranged in a straight line along the length of the base plate 9. The self-lubricating mechanism 7 provides automatic lubrication for the threaded pair between the movable seat 4 and the threaded shaft 61. The self-lubricating mechanism 7 includes a slider 71 and an oil-storage sponge 72 slidably connected inside the movable seat 4. The slider 71 and the oil-storage sponge 72 are in contact with each other. A sliding pin 73 is fixedly connected to the bottom of the slider 71, passing through the movable seat 4 and slidably connected to it. The end of the sliding pin 73 has an arc surface that abuts against the base plate 9. The position of the arc surface corresponds to the position of the protrusions 10. An oil outlet hole 76 is opened inside the movable seat 4, and the position of the oil outlet hole 76 corresponds to the positions of the oil-storage sponge 72 and the threaded shaft 61. A spring 74 is fitted around the outer side of the sliding pin 73. One end of the spring 74 is fixedly connected to the slider 71, and the other end is fixedly connected to the inner surface of the movable seat 4.

A sealing ring 75 is embedded in the side of the slider 71, and the sealing ring 75 is slidably connected to the inner surface of the movable seat 4. The sealing ring 75 increases the sealing between the slider 71 and the movable seat 4.

[0025] The specific implementation process of this utility model is as follows: In the initial state, the gantry frame 2 is located on the far left of the operating table 1. The operator places the four corners of the folded mattress cover onto the four sleeve rods 16 respectively, activates the control switch of the cylinder 13, and the telescopic shaft of the cylinder 13 retracts, pulling the linkage plate 14 upward. Under the guidance of the guide block 15, the linkage plate 14 rises smoothly, causing the two sleeve rods 16 on it to separate from the two sleeve rods 16 on the frame 12, thereby fully opening the mattress cover and forming an opening. Then, the main body of the mattress is supported by two arc pads 18, with its ends abutting against the stop block 19 for positioning. Subsequently, the motor 6 is started, and the motor 6 rotates forward, driving the threaded shaft 61 to rotate. Then, the moving seat 4 drives the gantry frame 16 to rotate. The gantry 2 moves at a constant speed from the initial end to the final end, then puts the mattress cover on the mattress, and finally removes the mattress. The motor 6 is then reversed, and the gantry 2 is driven back to the initial end to prepare for the next work cycle. The cylinder 13 is controlled to lower the linkage plate 14 and reset the sleeve rod 16. In addition, when the sliding pin 73 at the bottom of the moving seat 4 passes the protrusion 10 on the base plate 9, the protrusion 10 will push up the arc surface of the sliding pin 73, overcoming the elastic force of the spring 74 and pushing the slider 71 to slide upward in the moving seat 4. The slider 71 moves upward and squeezes the oil storage sponge 72. The lubricating oil absorbed in the oil storage sponge 72 is squeezed out and dripped or applied to the rotating threaded shaft 61 through the oil outlet 76, realizing automatic lubrication.
