Description

TECHNICAL FIELD

[0001] The utility model relates to paper processing and manufacturing equipment field, especially to the clamping device convenient to replace paper roll. BACKGROUND

[0002] In the paper processing and manufacturing process, the paper roll feeding mode is generally adopted for subsequent processing, such as dyeing, embossing, printing and other manufacturing processes.

[0003] Because the mass of some paper rolls is larger (generally about 1 ton), the mass of the paper roll is more than 100 kg, and in the production process of a general large factory, a large tool such as a gantry crane is used to put the paper roll with the paper roll into a U-shaped structure fixed groove (reference Figure 1 ) by suspension, the steps are as follows, first, the steel paper roll is unloaded from the equipment by using the crane, then the paper roll is inserted into the hollow cylinder of the paper roll, the position is adjusted, the paper roll and the paper roll are fixed by using the pin key, and then the paper roll and the paper roll are installed into the fixed groove by the crane. Finally, the paper roll is driven by a gear or a synchronous belt, so as to realize the conveying of the paper. The whole process is time-consuming and labor-consuming, and large equipment and a large number of personnel are required.

[0004] However, this method is not very convenient for small factories or small paper roll installation. Because many small factories do not have corresponding large hoisting equipment, manual method or hydraulic lifting equipment is often used to put the paper roll into the fixed groove. Another situation is that small orders or small batch trial production often use small paper rolls (1-200 kg) for frequent feeding and discharging. If this U-shaped structure is used, it is more time-consuming and labor-consuming.

[0005] In order to solve the above problems, a structure needs to be designed, which can be used for feeding and discharging of large paper rolls and small paper rolls, and can be used for feeding and discharging of small paper rolls by manual simple and fast method. To adapt to the production of small orders with frequent replacement of paper rolls. UTILITY MODEL CONTENT

DETAILED DESCRIPTION

[0021] The utility model will be described in further detail below in combination with the drawings and specific embodiments.

[0022] In order to facilitate understanding, the utility model will be described in further detail in combination with specific implementation cases but is not used to limit the utility model.

[0023] Embodiment: a kind of paper roll's clamping device for replacing paper roll easily, reference Figure 2 、 3 , 4, 5, the clamping device includes two locking devices 2, and the fixing seat 3 being arranged below the locking device 2, two locking devices 2 and the fixing seat 3 are arranged on the support 1 relative to horizontal, the fixing seat 3 and the support 1 are connected by bolt fixedly, so that the whole fixing seat 3 is in stable state, a cylinder 205 is equipped below one of locking devices 2, corresponding circular containing cavity 301 of corresponding size is equipped on the fixing seat 3 below the locking device 2, locking device 2 can rotate with the axis of cylinder 205 as the center, also can add a bearing between cylinder 205 and containing cavity 301, so that rotation is more smooth. Another locking device 2 is connected by bolt fixedly with the fixing seat 3, i. e. two locking devices 2 are in different state respectively, one is in stable state, and the other is in rotatable state on horizontal plane.

[0024] As Figure 3,4,5, the locking device 2 is composed of three parts, which are the upper cover 201, the base 202 and the buckle 203. One end of the upper cover 201 is hinged to the base 202 through the pivot 2011, so that the upper cover 201 can realize the opening and closing function, so as to loosen or lock the paper roller 4. The buckle 203 is a columnar structure, one end of the buckle 203 is also hinged to the base 202 through the pivot 2011, so as to realize the rotation of the buckle 203, the other end of the buckle 203 is provided with a nut 204, the nut 204 and the buckle 203 are provided with corresponding threads, so that the nut 204 can realize the change of stroke along the thread. A recess 2012 is provided at the movable end of the upper cover 201, the middle part of the buckle 203 can enter the recess 2012, when the paper roller 4 is installed on the base 202, the paper roller 4 is initially placed by buckling the upper cover 201, and then the buckle 203 is buckled into the recess 2012, the nut 204 is rotated to realize the shrinkage of the upper cover 201, so as to prevent the paper roller 4 and the locking device 2 from being separated due to accident. In order to prevent displacement of the paper roller 4 when it is placed in the base 202, a recess 2021 is provided on the upper surface of the base 202, so that the paper roller 4 is in a stable state after being placed.

[0025] The paper roller 4 is of a general structure and is made of stainless steel, and its two ends are placed in the locking devices 2 on the left and right sides. In order to prevent movement in the horizontal direction, two limiting rings 401 are provided at each end, and the width of the limiting ring 401 is adapted to the width of the locking device 2. The limiting ring 401 can be a circular sheet metal or a rotary bearing. The limiting ring 401 prevents the paper roller 4 from moving excessively in the left and right directions, so as to limit it within a controllable range.

[0026] The working principle and installation process will be described in detail below. After the paper of the previous paper roll 5 is used up, the nut 204 of the non-rotatable locking device 2 is loosened, so that the buckle 203 is loosened, and the upper cover 201 is further opened. One end of the paper roller 4 is held by a person, and the paper roller 4 is started to rotate. Because there is a cylindrical body 205 on the rotatable locking device 2, and the corresponding base 202 and fixed seat 3 are not fixedly connected, but are movably connected through the cylindrical body 205. Referring to Figure 6The paper roller 4 is rotated to a suitable angle as needed. Due to the axial support of the cylinder 205 and the fixed base 3, the paper roller 4 remains in a reliable state. At this time, only one end of the paper roller 4 is locked, while the other end is suspended. After removing the hollow paper tube of the used paper roll 5 from the paper roller 4, the new paper roll 5 is inserted into the appropriate position on the paper roller 4 manually or using a trolley. A pin is then inserted into the gap between the paper roller 4 and the paper roll 5 for tight fitting and fixation, ensuring a stable connection between them (this structure is not shown in the diagram as it is a general structure). The paper roller 4 is rotated again and moved into the locking device 2. The locking device 2 only serves to lock the paper roller 4, preventing accidental disengagement. The paper roller 4 is rotatable within the locking device 2. After installing the new paper roll 5, the paper roller 4 is connected to the synchronous motor via a belt, and paper feeding can begin.

[0027] This technical solution is particularly suitable for small factories or applications with a large number of small orders where frequent replacement of small paper rolls 5 is required. It requires minimal manpower, making replacement convenient, quick, and time-saving. This solution is also applicable to large paper rolls; if a crane is used, the entire paper roll 4 can be detached from the support 1. It has a wide range of applications.

[0028] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
