Description

Technical Field

[0001] This utility model relates to the technical field of nonwoven fabric production equipment, specifically to a paper tray feeding device for nonwoven fabric packaging. Background Technology

[0002] Nonwoven fabric, also known as non-woven cloth or non-woven material, is a sheet, web or pad made of oriented or randomly arranged fibers through friction, cohesion, bonding or a combination of these methods. It has the characteristics of high strength, good durability, strong filtration and mass production, and is therefore widely used in industries such as medical, hygiene, agriculture, packaging, clothing and construction.

[0003] After production, non-woven fabric is usually wound onto a roll to form a non-woven fabric roll, which facilitates subsequent transportation and use. After the non-woven fabric roll is formed, it needs to be packaged to protect the internal products, prevent moisture and dust, facilitate handling, and label information.

[0004] A prior art patent with publication number CN119117348A discloses a solution including a base, a U-shaped seat, a limiting unit, and a packaging mechanism. During the upward movement, friction between two rotating rollers and the film causes the upper part of the film to tend to move upwards; during the downward movement, friction between the two rotating rollers and the film causes the lower part of the film to tend to move downwards. This stretches the film across its width, facilitating its winding onto the nonwoven fabric roll. The pressing action of the two rotating rollers on the film, combined with the above process, ensures the film remains taut and does not fold or tangle, allowing it to be evenly spread and wound onto the nonwoven fabric roll. This avoids the problems of film folding and tangling affecting packaging quality and causing film waste.

[0005] As existing devices are used, the shortcomings of this technology have gradually become apparent, mainly in the following aspects:

[0006] When packaging rolls of nonwoven fabric, the diameter of the rolls varies, resulting in different diameters of the paper trays used for end protection. Existing devices cannot ensure coaxiality between multiple paper trays when feeding stacked paper trays.

[0007] As can be seen from the above, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0008] To address the shortcomings of existing technologies, this utility model provides a paper tray feeding device for non-woven fabric packaging, which solves the problem that in traditional technology, when packaging rolls of non-woven fabric, the diameter of the paper trays for end protection varies due to the different diameters of the rolls. Existing devices cannot satisfy the coaxiality problem between multiple paper trays when feeding stacked paper trays.

[0009] To achieve the above objectives, the present invention provides the following technical solution.

[0010] A non-woven fabric packaging tray feeding device includes a workbench, a support platform that is vertically raised and lowered above the workbench, a plurality of fixed-distance rods that are circumferentially arranged and radially slidable around the support platform, a horizontally arranged linkage disk that is rotatably arranged below the support platform, and a horizontally arranged connecting rod that is hinged to the outer edge of the upper surface of the linkage disk corresponding to each of the fixed-distance rods, the other end of the connecting rod being hinged to the fixed-distance rod.

[0011] As an optimized solution, a rotating cylinder is vertically and rotatably mounted on the worktable, and the linkage disc has a mounting hole and is fixed to the outer wall of the rotating cylinder through the mounting hole.

[0012] As an optimized solution, the workbench is fixed with a drive box by a frame, the output end of the drive box is fixed with a drive sprocket, and the outer wall of the rotating drum is fixed with a driven sprocket. The drive sprocket and the driven sprocket are connected by a chain.

[0013] As an optimized solution, a worm gear is rotatably provided inside the drive box, and a worm gear meshing with the worm gear is rotatably provided inside the drive box. A handwheel is rotatably provided outside the drive box, and the central axis of the handwheel is fixedly connected to the end of the worm gear. The central axis of the worm gear extends to the bottom of the drive box and is fixedly connected to the drive sprocket.

[0014] As an optimized solution, a drive sleeve is rotatably provided below the worktable. The inner wall of the drive sleeve is provided with internal threads. A vertically arranged screw is connected to the drive sleeve through the internal threads. The upper end of the screw passes through the rotating cylinder and is fixedly connected to the lower surface of the support platform.

[0015] As an optimized solution, a gear ring is fixedly connected to the outer wall of the drive sleeve, and a drive motor is fixedly connected to the lower surface of the worktable. The output shaft of the drive motor meshes with the gear ring using a gear.

[0016] As an optimized solution, guide rods are fixedly connected side by side to the lower surface of the support platform near its outer edge, and the guide rods are slidably mounted on the worktable in a vertical direction.

[0017] As an optimized solution, a positioning sleeve is rotatably mounted on the outer wall of the drive sleeve, and an annular groove is formed on the inner wall of the positioning sleeve. A positioning ring constrained within the annular groove is fixedly connected to the outer wall of the drive sleeve.

[0018] As an optimized solution, the outer wall of the positioning ring is fixedly connected to the lower surface of the worktable via a support frame.

[0019] As an optimized solution, a clearance groove is provided on the support platform for each of the fixed-distance rods, and the fixed-distance rods are slidably constrained within the clearance groove.

[0020] As an optimized solution, the upper surface of the workbench is fixedly connected to a slide rail corresponding to each of the spacers, and the lower end of each spacer is fixedly connected to a slide block that is slidably mounted on the slide rail.

[0021] As an optimized solution, two positioning rings are fixedly connected side by side from top to bottom on the outer wall of the rotating drum, with the two positioning rings located on the upper and lower sides of the worktable respectively.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] By stacking several paper trays on the support platform from top to bottom, and turning the handwheel, the chain drives the rotating drum to rotate. The rotating drum uses a linkage plate and a connecting rod to drive several spacer rods to slide along the clearance groove of the support platform, thereby adjusting the spacing between the spacer rods to meet the needs of paper trays of different diameters, and to ensure the coaxiality of the paper trays by abutting against the outer circumference of the paper trays.

[0024] The drive motor drives the drive sleeve to rotate, and the drive sleeve uses a screw to drive the support platform to rise and fall. As the paper trays are picked up one by one by the robotic arm, the support platform rises to continuously supply the paper trays. This is convenient and fast, improves the stability of the feeding process of several paper trays, and meets the packaging needs of cloth rolls of different diameters. Attached Figure Description

Detailed Implementation

[0028] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0029] like Figure 1 As shown, the non-woven fabric packaging paper tray feeding device includes a workbench 1, a support platform 2 that is vertically raised and lowered above the workbench 1, a number of fixed-distance rods 3 that are circumferentially arranged and radially slidable around the support platform 2, and a horizontally arranged linkage disk 9 that is rotatably arranged below the support platform 2. A horizontally arranged connecting rod 10 is hinged to the outer edge of the upper surface of the linkage disk 9 corresponding to each fixed-distance rod 3, and the other end of the connecting rod 10 is hinged to the fixed-distance rod 3.

[0030] A rotating drum 11 is vertically and rotatably mounted on the workbench 1. The linkage disc 9 has a mounting hole and is fixed to the outer wall of the rotating drum 11 through the mounting hole.

[0031] The workbench 1 is fixed with a drive box 15 by the frame. The output end of the drive box 15 is fixed with a drive sprocket 14. The outer wall of the drum 11 is fixed with a driven sprocket 12. The drive sprocket 14 and the driven sprocket 12 are connected by a chain 13.

[0032] A worm gear 16 is rotatably provided inside the drive box 15, and a worm 17 that meshes with the worm gear 16 is rotatably provided inside the drive box 15. A handwheel 18 is rotatably provided outside the drive box 15. The central axis of the handwheel 18 is fixedly connected to the end of the worm 17. The central axis of the worm gear 16 extends to the bottom of the drive box 15 and is fixedly connected to the drive sprocket 14.

[0033] A drive sleeve 20 is rotatably provided below the worktable 1. The inner wall of the drive sleeve 20 is provided with internal threads. The drive sleeve 20 is internally threaded and connected to a vertically arranged screw 21. The upper end of the screw 21 passes through the rotating cylinder 11 and is fixedly connected to the lower surface of the support platform 2.

[0034] A gear ring 22 is fixedly connected to the outer wall of the drive sleeve 20, and a drive motor 23 is fixedly connected to the lower surface of the worktable 1. The output shaft of the drive motor 23 meshes with the gear ring 22 using gears.

[0035] A stepper motor or a servo motor can be connected to the drive motor 23, so that the controller can send pulse signals to control the number of rotation steps of the stepper motor or servo motor, thereby precisely controlling the rotation angle (each pulse corresponds to a fixed angle increment).

[0036] Guide rods 6 are fixedly connected side by side to the lower surface of the support platform 2 near the outer edge. The guide rods 6 are slidably installed on the worktable 1 along the vertical direction.

[0037] The guide rod 6, the spacer rod 3, and the chain 13 are not in the same radial direction, thus achieving mutual misalignment and avoidance.

[0038] A positioning sleeve 24 is rotatably mounted on the outer wall of the drive sleeve 20. An annular groove is provided on the inner wall of the positioning sleeve 24, and a positioning ring is fixedly connected to the outer wall of the drive sleeve 20 and constrained in the annular groove.

[0039] The outer wall of the positioning ring is fixedly connected to the lower surface of the worktable 1 via the support frame 26.

[0040] Each fixed-distance rod 3 on the support platform 2 is provided with a relief groove 5, and the fixed-distance rod 3 is slidably constrained in the relief groove 5.

[0041] The upper surface of the workbench 1 is fixedly connected to a slide rail 7 corresponding to each spacer rod 3, and the lower end of the spacer rod 3 is fixedly connected to a slide block 8 that is slidably mounted on the slide rail 7.

[0042] Two positioning rings are fixedly connected side by side from top to bottom on the outer wall of the rotating drum 11, with the two positioning rings located on the upper and lower sides of the worktable 1 respectively.

[0043] The working principle of this device is as follows:

[0044] By stacking several paper trays 4 from top to bottom on the support platform 2, and by turning the handwheel 18, the chain 13 drives the rotating drum 11 to rotate. The rotating drum 11 uses the linkage disc 9 and the connecting rod 10 to drive several spacer rods 3 to slide along the clearance groove 5 of the support platform 2, thereby adjusting the spacing between the spacer rods 3 to meet the needs of paper trays 4 of different diameters, and to ensure the coaxiality of the paper trays 4 by abutting against the outer periphery of the paper trays 4.

[0045] The drive sleeve 20 is rotated by the drive motor 23, and the drive sleeve 20 drives the support platform 2 to rise and fall by the screw 21. As the paper trays 4 are picked up one by one by the robot, the support platform 2 rises to continuously supply the paper trays 4. This is convenient and fast, improves the stability of feeding several paper trays 4, and meets the packaging needs of cloth rolls of different diameters.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it.
