Technical Field

[0001] This utility model relates to the field of transfer equipment technology, and in particular to a paper roll unloading and transfer device. Background Technology

[0002] Paper rolls are made from paper produced by a papermaking machine and then cut and wound by a rewinder into rolls that meet national standards or user requirements for width and diameter. Common widths for Chinese paper rolls include 1575mm, 1092mm, 880mm, and 787mm. The rolls must have consistent tension, neat edges, flat joints, and prominent markings. They are used in various industrial applications such as rotary printing and automated packaging.

[0003] In the existing technology, when large rolls of paper are processed and used, they need to be transported to different processing steps. However, in the current processing of large rolls of paper, they are mostly transported and clamped by large equipment, which makes it extremely inconvenient to move them in crowded workshops. At the same time, the controllability of large equipment is poor, and it is easy to damage the surface of the large rolls of paper. Therefore, a paper roll unloading and transfer device is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a paper roll unloading and transfer device to solve the problem that in the current processing of large rolls of paper, they are mostly handled and clamped by large equipment, which makes it extremely inconvenient for them to move around in crowded workshops. At the same time, the controllability of large equipment is poor, which can easily damage the surface of the large rolls of paper.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a paper roll unloading and transfer device, comprising a mobile trolley, a fixed winding component fixedly mounted on the top of the mobile trolley, a movable winding component movably mounted on the mobile trolley, an auxiliary assist component movably embedded on the mobile trolley, a buffer pad embedded and snapped onto the edge of the mobile trolley near the auxiliary assist component, a push rod fixedly mounted on one side of the top of the mobile trolley, connecting slots correspondingly opened on the front and back edges of the mobile trolley, an installation slot and a connecting slide groove respectively opened on the upper surface of the mobile trolley, and a connecting spring provided on one side of the inner side of the connecting slide groove, a limiting device slidably mounted on the fixed winding component, the limiting device comprising a limiting plate arranged opposite to each other, an extension plate provided on the limiting plate, a screw threadedly connected to the extension plate, and a fixing piece at the bottom of the screw that can fit against the fixed winding component.

[0006] Furthermore, the bottom of the movable winding component is provided with a connecting support, the inner side of the connecting support is provided with a connecting roller, and the bottom of the connecting support is slidably inserted into the inside of the connecting groove.

[0007] Furthermore, the bottom of the assistive accessory is provided with an electric push rod, the top of the electric push rod is provided with an arc-shaped support plate, and the inner wall of the arc-shaped support plate is provided with a protective soft pad.

[0008] Furthermore, the movable winding member has the same structural shape as the fixed winding member, and the length of the connecting roller on the movable winding member is two-thirds of the length of the connecting roller on the fixed winding member, and the movable winding member and the fixed winding member are parallel to each other.

[0009] Furthermore, the shape and size of the arc-shaped support plate match the shape and size of the mounting groove, and the arc-shaped support plate is movably connected to the inner bottom wall of the mounting groove via an electric push rod.

[0010] Furthermore, the shape and size of the connecting slot match the shape and size of the buffer pad, and the buffer pad is snapped into place inside the connecting slot.

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

[0012] 1. This paper roll unloading and transfer device, by setting buffer pads, protects the large roll of paper when it is laid down onto the device, preventing damage to the roll from the edges of the moving trolley. The large roll of paper is then placed between the fixed winding component and the movable winding component, and is further supported by the arc-shaped support plate on the auxiliary component. At the same time, the protective soft pad on the arc-shaped support plate is used to protect the roll of paper and prevent damage to the outer surface. Then, by pushing the push rod, the moving trolley is moved to transfer the large roll of paper, which effectively facilitates the transfer and use of paper rolls in crowded workshops and improves its ease of use.

[0013] 2. This paper roll unloading and transfer device, through the installation of connecting springs, retracts under the relative force of the fixed winding component and the weight of the large roll of paper, thereby driving the movable winding component to move in position. This effectively adjusts the working distance between the fixed and movable winding components to accommodate rolls of paper of different sizes, improving its applicability. At the same time, when the roll is being handled, the large roll of paper is effectively pushed out by the action of the electric push rod, reducing the physical effort required for manual handling, thus facilitating its operation and improving its practicality.

[0014] 3. The limiting plate can make the paper rolls of the fixed winding component more neat, and the winding plate can slide to adjust the spacing to suit paper rolls of different widths. At the same time, the limiting plate can fix the fixing plate to the fixed winding component by rotating the screw. The limiting plate greatly improves the neatness of the paper rolls.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0025] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be selected to be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.

[0026] like Figures 1 to 6As shown, this utility model provides a paper roll unloading and transfer device, including a mobile trolley 1, a fixed winding component 2 fixedly installed on the top of the mobile trolley 1, a movable winding component 3 movably installed on the mobile trolley 1, an auxiliary component 5 movably embedded on the mobile trolley 1, and a buffer pad 4 embedded and snapped on the edge of the mobile trolley 1 near the auxiliary component 5.

[0027] A push rod 101 is fixedly installed on one side of the top of the mobile trolley 1. Connecting slots 102 are opened on the front and back edges of the mobile trolley 1 respectively. An installation slot 103 and a connecting slide 104 are opened on the upper surface of the mobile trolley 1 respectively, and a connecting spring 105 is provided on one side of the inside of the connecting slide 104.

[0028] Specifically, the bottom of the movable take-up piece 3 is provided with a connecting support 301, the inner side of the connecting support 301 is provided with a connecting roller 302, and the bottom of the connecting support 301 is slidably inserted into the inside of the connecting groove 104. When in use, the movable take-up piece 3 is supported by the connecting support 301, and the connecting roller 302 prevents the paper roll from slipping out when the paper roll rotates, thus effectively ensuring the stability of the paper roll during transport. Furthermore, the fixed take-up piece 2 is provided with a limiting device 6, which includes a limiting plate 61 arranged opposite to it. The limiting plate 61 is provided with an extension plate 62, and a screw 63 is threadedly connected to the extension plate 62. The bottom of the screw 63 is provided with a fixing piece 64 that can fit with the fixed take-up piece. The limiting plate 61 makes the paper roll of the fixed take-up piece more neat, and the distance of the take-up piece can be adjusted to suit paper rolls of different widths. At the same time, the limiting plate 61 can fix the fixing piece 64 to the fixed take-up piece 2 by rotating the screw 63. The limiting plate 61 greatly improves the neatness of the paper roll. Specifically, a limiting groove 303 is provided at the connection between the connecting support 301 and the connecting roller 302, and a telescopic spring 305 is provided on the inner bottom wall of the limiting groove 303, with a support 304 provided on the top of the telescopic spring 305. This allows the movable winding member 3 to effectively limit the installation of the connecting roller 302 through the limiting groove 303 and support it through the support 304 during use. Furthermore, when the movable winding member 3 is subjected to the weight of the rolled paper, the telescopic spring 305 provides elastic support and resets it, reducing the pressure on the inner shaft of the connecting roller 302, preventing deformation, and extending its service life.

[0029] Specifically, the bottom of the auxiliary component 5 is equipped with an electric push rod 501, and the top of the electric push rod 501 is equipped with an arc-shaped support plate 502, with a protective soft pad 503 on the inner wall of the arc-shaped support plate 502. By configuring the auxiliary component 5, the device provides auxiliary support for the roll of paper during use through the arc-shaped support plate 502. Simultaneously, the protective soft pad 503 on the arc-shaped support plate 502 protects the roll of paper, preventing damage to its outer surface. Furthermore, when removing the roll of paper, the electric push rod 501 pushes the large roll of paper out, reducing the physical effort required for manual handling and thus facilitating its operation.

[0030] Specifically, the movable winding member 3 has the same structural shape as the fixed winding member 2, and the length of the connecting roller 302 on the movable winding member 3 is two-thirds of the length of the connecting roller 302 on the fixed winding member 2. Furthermore, the movable winding member 3 and the fixed winding member 2 are parallel to each other. This arrangement of the movable winding member 3 and the fixed winding member 2 effectively ensures balance between them during use, preventing the paper roll from slipping out. Simultaneously, the corresponding arrangement of the connecting roller 302 effectively reduces the volume of the movable winding member 3, facilitating movement and adjustment.

[0031] Specifically, the shape and size of the arc-shaped pallet 502 match the shape and size of the mounting groove 103, and the arc-shaped pallet 502 is movably connected to the inner bottom wall of the mounting groove 103 via an electric push rod 501. By configuring the arc-shaped pallet 502 and the mounting groove 103, the auxiliary component 5, under the action of the electric push rod 501, effectively causes the arc-shaped pallet 502 to retract into the mounting groove 103, thereby ensuring the flatness of the upper surface of the moving trolley 1 for assembly of large roll paper handling.

[0032] Specifically, the shape and size of the connecting slot 102 match the shape and size of the buffer pad 4, and the buffer pad 4 is snapped into place inside the connecting slot 102. The connection slot 102 and the buffer pad 4 facilitate the installation and replacement of the buffer pad 4, saving subsequent maintenance costs. Simultaneously, the snapping mechanism of the connecting slot 102 prevents the buffer pad 4 from shifting under pressure, thus ensuring the stability of the installation and use.

[0033] In use, the vertically placed large roll of paper is tilted and laid on the moving trolley 1 with the buffer pad 4 as the fulcrum. The tilted large roll of paper is placed between the fixed winding member 2 and the movable winding member 3. Then, with the help of the auxiliary component 5, the large roll of paper is placed smoothly on the outer wall of the connecting roller 302 set on the fixed winding member 2 and the movable winding member 3. It is further supported by the arc-shaped support plate 502 on the auxiliary component 5. At the same time, the protective soft pad 503 set on the arc-shaped support plate 502 is used to protect the roll of paper and avoid damage to the outer surface of the roll of paper. Then, by pushing the push rod 101, the moving trolley 1 is moved to transfer the large roll of paper. The operation of the device is completed in the above way.

[0034] In summary, this paper roll unloading and transfer device, by setting a connecting spring 105, causes it to retract under the relative force of the fixed winding member 2 and the weight of the large roll of paper, and drives the movable winding member 3 to move in position. This effectively adjusts the working distance between the fixed winding member 2 and the movable winding member 3 to accommodate rolls of paper of different sizes, thus improving its applicability. At the same time, when the roll is being handled, the large roll of paper is effectively pushed out by the electric push rod 501, reducing the physical effort required for manual handling, thereby facilitating its operation and improving its practicality.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
