Description

Technical Field

[0001] This utility model belongs to the technical field of self-adhesive production equipment, and in particular relates to an unloading lifting platform. Background Technology

[0002] Self-adhesive labels, also known as pressure-sensitive labels, are composite materials made of paper, film, or special materials as the face stock, coated with adhesive on the back, and with silicone-coated release paper as the backing paper.

[0003] However, existing technologies have some problems: existing self-adhesive labels require a roller winding operation during production, that is, the self-adhesive is wound onto the target roller, and then the roller is removed for the next process. However, the roller with the self-adhesive wrapped is heavy and it is dangerous to remove it from a height, which is not conducive to production operations. Therefore, we propose an unwinding lifting platform. Utility Model Content

The movable blocks extend into the movable groove. The top plate is movably connected to the side frames through the movable blocks extending into the movable groove. A set of winding unloading components is fixedly installed on the upper outer wall of the top plate.

[0006] As a preferred embodiment of this invention, the lower end of the base is fixedly equipped with multiple casters.

[0007] As a preferred embodiment of this utility model, the outer walls on the left and right sides of the side frame are provided with corresponding limiting holes, which are located on the left and right sides of the movable groove and are interconnected.

[0008] As a preferred embodiment of this invention, a protrusion is fixedly connected to the inner wall of the side frame, and the protrusion is located on the rear side of the opening.

[0009] As a preferred embodiment of this utility model, a hinge block is fixedly connected to the upper end of the electric push-pull rod, and a positioning hole is provided through the outer wall of the hinge block.

[0010] As a preferred embodiment of this utility model, the outer wall of the rear side of the top plate is provided with an inwardly recessed groove, which is used to connect with the protrusion.

[0011] As a preferred embodiment of this utility model, the lower outer wall of the top plate is fixedly connected with two sets of fixing ears, each set of fixing ears being arranged in pairs. The outer wall of the fixing ears is provided with through holes, and the top plate is movably connected to the hinge block through the fixing ears. The through holes correspond to the positioning holes.

[0012] As a preferred embodiment of this utility model, the outer walls on both sides of the fixing ear are respectively provided with a nut and a screw shaft, and one side of the screw shaft is threadedly connected to the nut through a through hole and a positioning hole.

[0013] As a preferred embodiment of this utility model, both sides of the outer wall of the movable block are provided with inwardly recessed telescopic grooves. A telescopic block is movably connected inside the telescopic groove. One end of the telescopic block located inside the telescopic groove is connected to a telescopic spring. The other end of the telescopic spring is connected to the inner wall of the telescopic groove. The other end of the telescopic block extends out of the telescopic groove and into the limiting hole.

[0014] In a preferred embodiment of this utility model, the unwinding assembly includes a buffer seat fixedly installed on the upper outer wall of the top plate. The upper outer wall of the buffer seat is provided with an inwardly recessed buffer groove. The buffer groove has a convex cross-section. A connecting plate is provided inside the buffer groove. A limiting plate is fixedly connected to one end of the connecting plate inside the buffer groove. The limiting plate and the connecting plate are arranged in a T-shape.

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

[0016] 1. This utility model uses an electric telescopic rod to move the side frame up and down, which facilitates the adjustment of the height of the top plate. By adjusting the two side frames, it is easy to adjust the two unloading components to be arranged in a flat state, which facilitates the unloading of the self-adhesive. The top plate is pushed by an electric push-pull rod, and the top plate is limited and connected to the movable groove by a movable block, which facilitates rotation around the movable block as the center point. This makes it easy for the unloading components to contact the roller roll wrapped with self-adhesive, avoiding the force generated by the roller roll wrapped with self-adhesive falling from a height, which can easily damage the unloading components. It also effectively solves the safety hazard problem of removing the roller roll wrapped with self-adhesive from a height.

[0017] 2. This utility model uses a hinge block that extends between the fixed ears to make the positioning hole correspond to the through hole. The screw shaft passes through the through hole and the positioning hole and is threadedly connected to the nut, which facilitates the limiting of the hinge block. This makes it easier for the electric push-pull rod to push the top plate when it is in operation. The movable block is limited and connected inside the movable groove, thereby realizing the rotation of the top plate. This facilitates the unwinding of the roller roll wrapped with self-adhesive, effectively improving the safety of unwinding.

[0018] 3. In this utility model, when the movable block extends into the movable groove, the telescopic block contacts the inner wall of the movable groove. Under the action of force, the telescopic block drives the telescopic spring to retract into the telescopic groove. When the telescopic groove corresponds to the limiting hole, the telescopic spring rebounds, driving the telescopic block to extend into the limiting hole, thereby limiting the movable block and thus limiting the top plate.

[0025] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0026] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] Example 1:

[0028] like Figures 1 to 5 As shown in the figure, an embodiment of the present invention provides a winding unloading lifting platform, including a base 1 and a top plate 3 disposed on the upper end of the base 1. A set of electric telescopic rods 12 and tension rods 13 are fixedly installed on the upper end of the base 1. A set of rectangularly arranged side frames 2 are provided on the upper end of the base 1. The lower end of the side frames 2 is fixedly connected to the upper end of the electric telescopic rods 12 and tension rods 13. A partition 21 is fixedly connected inside the side frames 2. An electric push-pull rod 22 is fixedly installed on the upper end of the partition 21. An opening 23 is provided through the upper outer wall of the side frames 2. An inwardly recessed movable groove 24 is provided on the upper outer wall of the side frames 2. The movable groove 24 is located in front of the opening 23 and is interconnected with it. The top plate 3 extends into the opening 23 and is connected to the electric push-pull rod 22. A set of movable blocks 5 are fixedly connected to the front side of the top plate 3. The movable blocks 5 extend into the movable... Inside the movable groove 24, the top plate 3 extends into the movable groove 24 via a movable block 5 and is movably connected to the side frame 2. A set of unloading components 4 is fixedly installed on the upper outer wall of the top plate 3. The side frame 2 is moved up and down by the operation of the electric telescopic rod 12, which facilitates the adjustment of the height of the top plate 3. By adjusting the two side frames 2, it is easy to adjust the two unloading components 4 to be arranged in a flat state, which is convenient for unloading the self-adhesive. The top plate 3 is pushed by the electric push-pull rod 22, and the top plate 3 is limited and connected to the movable groove 24 by the movable block 5, which is convenient for rotating around the movable block 5 as the center point. This facilitates the contact between the unloading components 4 and the roller roll wrapped with self-adhesive, avoiding the force generated by the roller roll wrapped with self-adhesive falling from a height, which could easily damage the unloading components 4. It also effectively solves the problem of safety hazards caused by removing the roller roll wrapped with self-adhesive from a height.

[0029] like Figure 1 As shown, a plurality of casters 11 are fixedly installed at the lower end of the base 1; the casters 11 facilitate the movement of the lifting platform.

[0030] like Figure 2 As shown, the outer walls of the left and right sides of the side frame 2 are provided with corresponding limiting holes 25. The limiting holes 25 are located on the left and right sides of the movable groove 24 and are interconnected. The inner wall of the side frame 2 is fixedly connected with a protrusion 26, which is located on the rear side of the opening 23. The limiting holes 25 are used to limit the movable block 5 and facilitate the rotation of the top plate 3. The movable block 5 is limited, and the protrusion 26 is used to facilitate the connection of the top plate 3 to the inside of the opening 23.

[0031] like Figure 2 As shown, a hinge block 222 is fixedly connected to the upper end of the electric push-pull rod 22, and a positioning hole 221 is provided through the outer wall of the hinge block 222; as shown Figure 3As shown, the outer wall of the rear side of the top plate 3 is provided with an inwardly recessed groove 34, which is used to connect with the protrusion 26; two sets of fixing ears 31 are fixedly connected to the lower outer wall of the top plate 3, with each set of fixing ears 31 arranged in pairs, and a through hole 311 is provided through the outer wall of the fixing ears 31. The top plate 3 is movably connected to the hinge block 222 through the fixing ears 31, and the through hole 311 corresponds to the positioning hole 221; nuts 32 and screws 33 are respectively provided on the outer walls of the two sides of the fixing ears 31, and the through hole 311 is provided through one side of the screw 33. 11 and positioning hole 221 are threadedly connected to nut 32; the hinge block 222 extends between the fixed ears 31, so that positioning hole 221 corresponds to through hole 311. The screw shaft 33 passes through through hole 311 and positioning hole 221 and is threadedly connected to nut 32, which facilitates the limiting of hinge block 222. This makes it easier for the electric push-pull rod 22 to push the top plate 3 when it is in operation. It is connected to the movable block 5 in the movable groove 24 to realize the rotation of the top plate 3, which facilitates the unwinding of the roller roll wrapped with self-adhesive and effectively improves the safety of unwinding.

[0032] like Figure 4 As shown, both sides of the outer wall of the movable block 5 are provided with inwardly recessed telescopic grooves 52. A telescopic block 51 is movably connected inside the telescopic groove 52. One end of the telescopic block 51 located inside the telescopic groove 52 is connected to a telescopic spring 53. The other end of the telescopic spring 53 is connected to the inner wall of the telescopic groove 52. The other end of the telescopic block 51 extends out of the telescopic groove 52 and into the limiting hole 25. When the movable block 5 extends into the movable groove 24, the telescopic block 51 contacts the inner wall of the movable groove 24. Under the action of force, the telescopic block 51 drives the telescopic spring 53 to retract into the telescopic groove 52. When the telescopic groove 52 corresponds to the limiting hole 25, the telescopic spring 53 rebounds, driving the telescopic block 51 to extend into the limiting hole 25, thereby limiting the movable block 5 and thus limiting the top plate 3.

[0033] like Figure 5As shown, the unwinding assembly 4 includes a buffer seat 41 fixedly installed on the upper outer wall of the top plate 3. The upper outer wall of the buffer seat 41 has an inwardly recessed buffer groove 411. The buffer groove 411 has a convex cross-section. A connecting plate 43 is provided inside the buffer groove 411. One end of the connecting plate 43 located inside the buffer groove 411 is fixedly connected to a limiting plate 44. The limiting plate 44 and the connecting plate 43 are arranged in a T-shape. A plurality of buffer springs 45 are connected to the lower outer wall of the limiting plate 44. The lower ends of the buffer springs 45 are connected to the inner wall of the buffer groove 411. The connecting plate 43... The upper end extends to the outside of the buffer seat 41. The connecting plate 43 is fixedly connected to a semi-circular placement plate 42 at one end outside the buffer seat 41. During the unwinding process, the roller wrapped with self-adhesive falls into the placement plate 42. Under the influence of force, the placement plate 42 drives the connecting block, which in turn drives the limiting block. The limiting block compresses the buffer spring 45 into the buffer groove 411. With the elasticity of the buffer spring 45, the placement plate 42 rebounds after being subjected to force, thereby achieving the effect of buffering and shock absorption of the placement plate 42. This improves the protection against damage to the unwinding assembly 4 during unwinding under the influence of force.

[0034] Working principle of Example 1:

[0035] In use, the electric telescopic rod 12 drives the side frame 2 to move up and down, facilitating the adjustment of the height of the top plate 3. Adjusting the two side frames 2 also allows the two unloading components 4 to be arranged in a flat position, facilitating the unloading of the self-adhesive tape. The electric push-pull rod 22 pushes the top plate 3, which is connected to the movable groove 24 by a movable block 5, allowing rotation around the movable block 5. This facilitates contact between the unloading components 4 and the rollers wrapped with self-adhesive tape, causing the rollers to fall into the placement plate 42. Under the influence of force, the placement plate 42 drives the connecting block, which in turn drives the limiting block. The limiting block compresses the buffer spring 45 into the buffer groove 411. Combined with the rebounding property of the buffer spring 45, this facilitates the rebound of the placement plate 42 after being subjected to force, achieving a buffering and shock-absorbing effect. This improves the protection against damage to the unloading components 4 under the influence of force during unloading.
