Description

Technical Field

[0001] This utility model relates to the field of paper tearing device technology, specifically a horizontally adjustable back paper tearing device. Background Technology

[0002] Most foam protective paper in daily life has tear lines at equal intervals, and most foam protective paper has three or more layers. Therefore, in the recycling of foam protective paper, most of the time the foam protective paper is separated and the back is torn open, which facilitates the recycling and processing efficiency of foam protective paper. Continuous paper with tear lines between adjacent foam sheets is also widely used. Continuous paper with tear lines between two sheets of foam, and the ability to tear along the perforated lines after local punching, have the characteristics of easy tearing. Traditional foam paper also requires tearing as many sheets as needed. However, in order to protect the front structure of the foam paper, a device is needed to complete the tearing action from the back.

[0003] Existing paper-tearing devices cannot restrict the position of the foam paper when tearing it. During use, they may fail to tear the foam paper along the tear line, resulting in damage to the foam paper. Most existing paper-tearing devices tear the foam paper by causing relative displacement of the foam paper on both sides of the tear line. This method cannot tear the foam paper gradually during use, which may lead to damage to the foam paper. Utility Model Content

[0008] As a preferred embodiment of this utility model, the center of the bracket is a horizontal plate-like structure, and the upper end of the conveying roller movably installed inside the bracket is located above the horizontal structure of the bracket and contacts the lower end of the limiting roller; the conveying roller can drive the foam paper to move.

[0009] As a preferred embodiment of this utility model, the limiting roller, the conveying roller and the bracket are rotatably connected, the front end of the conveying roller is fixedly connected to the shaft of the drive motor by an insertion method, and a rectangular opening structure is provided on the left side of the outlet; the limiting roller can conveniently limit the position of the foam paper.

[0010] As a preferred embodiment of this utility model, the outlet and the internally movably mounted conveying roller are rotatably connected, the limiting posts are symmetrically installed below the transmission plate, the transmission plate is equidistantly installed above the limiting block via the limiting posts, and the limiting posts and the limiting block are slidably connected; the limiting posts can conveniently restrict the movement direction of the transmission plate.

[0011] As a preferred embodiment of this utility model, the transmission plate has a downward-pointing sloping structure on the front side of its bottom center, the support plate has a protruding structure on its right side that matches the spacing of the transmission plate, the transmission block is movably connected to the base plate via an electric push rod, the top of the transmission block has a plate-like structure, and the rear side of the top surface of the transmission block has an upward-pointing sloping structure; the transmission block can lift the transmission plate.

[0012] As a preferred embodiment of this utility model, the pressing piston is fixedly connected to the bracket via a connecting frame, the connecting plate is movably connected to the connecting frame via the pressing piston, and the connecting column is slidably connected to the connecting plate; the connecting plate can restrict the movement direction of the connecting column.

[0013] As a preferred technical solution of this utility model, the pressure plate is installed directly above each transmission plate via a connecting column, the spring is located between the pressure plate and the connecting plate, the left end of the limiting plate is provided with a toothed structure, and the left end of the limiting plate is flush with the left end of the bracket; the limiting plate facilitates the tearing of the foam paper along the tear line.

[0014] Compared with the prior art, this utility model provides a horizontally adjustable back-side paper tearing device, which has the following advantages:

[0015] 1. This utility model features a downward-pressing piston with a connecting plate fixedly installed at its bottom. The connecting frame restricts the position of the downward-pressing piston. When the downward-pressing piston extends, it drives the connecting plate to move downward. Since the connecting column and the connecting plate form a sliding connection, when the bottom surface of the right-side limiting plate of the connecting plate contacts the bracket, the limiting plate will clamp the foam paper with the bracket. At the same time, the pressure plate at the bottom of the connecting column will contact the transmission plate and clamp the foam paper. This method can restrict the position of the foam paper during the tearing process, preventing the foam paper from shifting and causing the tear to deviate from the tear line.

[0016] 2. This utility model features a transmission plate with symmetrically installed limiting posts below it. The transmission plate is equidistantly installed above the limiting blocks via the limiting posts, forming a sliding connection between them. The center front of the bottom surface of the transmission plate has a downward-pointing slope structure, and the right side of the support plate has a protrusion matching the spacing of the transmission plate. The transmission block is movably connected to the base plate via an electric push rod. The top of the transmission block has a plate-like structure, and the rear side of its top surface has an upward-pointing slope structure. As the transmission block moves backward under the drive of the electric push rod, the slope structure at the rear end of the transmission block engages with the slope structure of the transmission plate, and the electric push rod lifts the transmission plates one by one, thereby causing the transmission plate to move the foam paper and pressure plate upward. This method can gradually tear the foam paper along the tear line, preventing damage to the foam paper during the tearing process. Attached Figure Description

[0025] Please see Figure 1 - Figure 4In this embodiment, a horizontally adjustable back-side paper-tearing device includes: a base plate 1, a bracket 11 fixedly mounted on the top of the base plate 1, an outlet 12 fixedly mounted on the top of the base plate 1, a limiting roller 13 movably mounted on the top of the bracket 11, a conveying roller 14 movably mounted below the bracket 11 and inside the outlet 12, a drive motor 15 fixedly mounted on the front side of the bracket 11 and the outlet 12, a support plate 16 fixedly mounted on the top of the base plate 1, a limiting block 17 fixedly mounted on the top of the base plate 1, a limiting post 18 inserted above the limiting block 17, a transmission plate 19 fixedly mounted at the top of the limiting post 18, a fixing frame 110 fixedly mounted on the top of the base plate 1, an electric push rod 111 fixedly mounted on the rear side of the fixing frame 110, and a transmission block 112 fixedly mounted at the rear end of the electric push rod 111.

[0026] The center of the bracket 11 is a horizontal plate-like structure. The upper end of the conveyor roller 14, which is movably installed inside the bracket 11, is located above the horizontal structure of the bracket 11 and contacts the lower end of the limiting roller 13. The limiting roller 13, the conveyor roller 14, and the bracket 11 are rotatably connected. The front end of the conveyor roller 14 is fixedly connected to the rotating shaft of the drive motor 15 by an insertion method. A rectangular opening structure is provided on the left side of the outlet 12. The outlet 12 is rotatably connected to the conveyor roller 14 movably installed inside. The limiting posts 18 are symmetrically installed on the transmission plate 19. Below, the transmission plate 19 is installed above the limiting block 17 at equal distances from the front and rear via the limiting post 18. The limiting post 18 and the limiting block 17 form a sliding connection. The front side of the center of the bottom surface of the transmission plate 19 is provided with a slope structure pointing diagonally downward. The right side of the support plate 16 is provided with a protrusion structure that matches the distance between the transmission plate 19 and the support plate 16. The transmission block 112 is movably connected to the base plate 1 via the electric push rod 111. The top of the transmission block 112 is provided with a plate-like structure, and the rear side of the top surface of the transmission block 112 is provided with a slope structure pointing diagonally upward.

[0027] Specifically, the base plate 1 can restrict the position of the bracket 11. The bracket 11 has vertically upward protrusions on both the front and rear sides to restrict the position of the foam paper. The limiting roller 13 and the conveying roller 14 clamp the foam paper. When the drive motor 15 drives the conveying roller 14 to rotate, the foam paper will move to the left under the drive of the conveying roller 14. The support plate 16 can support the foam paper. The limiting block 17 is symmetrically installed on the top of the base plate 1 with the center of the transmission block 112 as the reference. The transmission plate 19 is installed on the top of the transmission block 112 at equal distances from the front and rear through the limiting post 18. The center of the transmission plate 19 is provided with a slope structure. When the transmission block 112 moves backward under the drive of the electric push rod 111, the slope structure at the rear end of the transmission block 112 is engaged with the slope structure of the transmission plate 19, and the transmission plate 19 is lifted up under the drive of the electric push rod 111. The fixing frame 110 can restrict the position of the front end of the electric push rod 111.

[0028] A connecting frame 2 is fixedly installed above the bracket 11. A pressing piston 21 is inserted above the connecting frame 2. A connecting plate 22 is fixedly installed at the bottom of the pressing piston 21. A connecting column 23 is inserted above the connecting plate 22. A spring 24 is inserted on the outside of the connecting column 23. A pressure plate 25 is fixedly installed at the bottom of the connecting column 23. A limiting plate 26 is fixedly installed below the connecting plate 22. The pressing piston 21 is fixedly connected to the bracket 11 through the connecting frame 2. The connecting plate 22 is movably connected to the connecting frame 2 through the pressing piston 21. The connecting column 23 is slidably connected to the connecting plate 22. The pressure plate 25 is installed directly above each transmission plate 19 through the connecting column 23. The spring 24 is located between the pressure plate 25 and the connecting plate 22. The left end of the limiting plate 26 is provided with a toothed structure, and the left end of the limiting plate 26 is flush with the left end of the bracket 11.

[0029] Specifically, the connecting frame 2 can restrict the position of the pressing piston 21. When the pressing piston 21 extends, it will drive the connecting plate 22 to move downward. Since the connecting column 23 and the connecting plate 22 form a sliding connection, when the bottom surface of the right limit plate 26 of the connecting plate 22 contacts the bracket 11, the pressure plate 25 at the bottom of the connecting column 23 will contact the transmission plate 19 to clamp the foam paper. When the transmission plate 19 is lifted by the transmission block 112, it will drive the pressure plate 25 to move upward to compress the spring 24. The toothed structure at the left end of the limit plate 26 can facilitate tearing the foam paper along the tear line.

[0030] In use, a connecting plate 22 is fixedly installed at the bottom of the pressing piston 21. The connecting bracket 2 can restrict the position of the pressing piston 21. When the pressing piston 21 extends, it will drive the connecting plate 22 to move downward. Since the connecting post 23 and the connecting plate 22 form a sliding connection, when the bottom surface of the right limit plate 26 of the connecting plate 22 contacts the bracket 11, the limit plate 26 will clamp the foam paper with the bracket 11. At the same time, the pressure plate 25 at the bottom of the connecting post 23 will contact the transmission plate 19 to clamp the foam paper. When placing the foam paper, the placement direction is conducive to tearing it from the back of the foam paper. This method can restrict the position of the foam paper during the tearing process and prevent the foam paper from shifting and causing the tear to deviate from the tear line. The limit posts 18 are symmetrically installed on the left and right sides below the transmission plate 19. The transmission plate 19 is installed on the limit block 17 at equal distances from the front and back through the limit posts 18. Above, the limiting post 18 and the limiting block 17 form a sliding connection. The front side of the center of the bottom surface of the transmission plate 19 is provided with a slope structure pointing diagonally downward. The right side of the support plate 16 is provided with a protrusion structure that matches the spacing of the transmission plate 19. The transmission block 112 is movably connected to the base plate 1 through the electric push rod 111. The top of the transmission block 112 is provided with a plate-like structure, and the rear side of the top surface of the transmission block 112 is provided with a slope structure pointing diagonally upward. When the transmission block 112 moves backward under the drive of the electric push rod 111, the slope structure at the rear end of the transmission block 112 engages with the slope structure of the transmission plate 19, and under the drive of the electric push rod 111, it lifts the transmission plate 19 one by one, thereby causing the transmission plate 19 to drive the foam paper and the pressure plate 25 to move upward. This method can gradually tear the foam paper along the tear line, avoiding damage to the foam paper during the tearing process.
