Description

Technical Field

[0001] This utility model relates to a carbonless copy paper rewinding machine, belonging to the technical field of rewinding machines. Background Technology

[0002] Carbonless copy paper is a novel type of copy paper. Its key feature is that writing can be done on the top layer without needing a pre-coated ink layer. It's a type of invisible copy paper with direct copying and direct color development capabilities. Its color development primarily occurs when, under external force, the pressure-sensitive pigments and oil solution within the microcapsules leak out and react with the developer, resulting in a staining reaction and thus achieving the copying effect. It is mainly used for multi-part forms, invoices, continuous financial documents, and general business financial documents.

[0003] Chinese Patent Publication No. (CN 215710364 U) discloses a rewinding machine for carbonless copy paper processing, including a base frame. A feeding block is welded to the top of the base frame, and a first support is welded to the top of the base frame. A first servo motor is welded to the front side wall of the first support, and the output shaft of the first servo motor passes through the first support and is connected to a rotating disk via a coupling. The machine automatically feeds the raw material into the rollers via the feeding block, the first servo motor, the rotating disk, and the clamping mechanism. A second servo motor drives a second pulley to rotate, which in turn drives a first pulley and belt to rotate. The first pulley then drives a winding roller to rotate, thereby rewinding the carbonless copy paper. A hydraulic rod adjusts the position of a tension wheel to facilitate paper tension adjustment. A tension detection wheel and a tension sensor detect the paper tension. A telescopic rod, a spring, and a pressure wheel press the paper during winding.

[0004] A rewinding machine is used when rewinding carbonless copy paper. After the carbonless copy paper is rewound, it needs to be disassembled and replaced. Since there is a lot of carbonless copy paper wrapped on the rewinding roller, the rewinding roller is quite heavy. If the operator disassembles it directly, the operator may not be able to hold the rewinding roller firmly due to the weight. This may cause the rewinding roller to pull the rewounded carbonless copy paper to fall to the ground, which may damage the rewounded carbonless copy paper and make it inconvenient for the operator to use.

[0005] To address this, a carbonless copy paper rewinding machine is proposed. Utility Model Content

[0029] In the following description, only certain exemplary embodiments are briefly described.

Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0030] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0031] Example 1

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, this utility model embodiment provides a carbonless copy paper rewinding machine, comprising:

[0033] The winding assembly 1 includes a base plate 101. Guide rollers 102 are movably connected to the left side of the top of the base plate 101. Tension rollers 103 are movably connected to the middle of the top of the base plate 101. A winding roller 104 is provided on the right side of the top of the base plate 101. A first flange 105 is movably connected to the rear side of the top of the base plate 101. A second flange 106 is movably connected to the front side of the top of the base plate 101. Fixing bolts 108 are threadedly connected to both the front and rear sides of the winding roller 104. The outer sides of the fixing bolts 108 are threadedly connected to the surfaces of the first flange 105 and the second flange 106. A rotary motor 107 is fixedly installed on the front side of the surface of the base plate 101. The output end of the rotary motor 107 is fixedly connected to the front side of the second flange 106.

[0034] The unloading assembly 2 includes a drive motor 201 and screw blocks 203. The drive motor 201 is fixedly installed on the top of the base plate 101. Both screw blocks 203 are located on the top of the base plate 101. Mounting rods 204 are fixedly installed on the right side of both screw blocks 203. Moving blocks 205 are fixedly installed on the surface of both mounting rods 204. Connecting rods 206 are movably connected to the outer side of each of the four moving blocks 205. U-shaped plates 207 are movably connected to the outer side of each of the four connecting rods 206. Support plates 208 are fixedly installed at the other end of each of the four U-shaped plates 207. A bidirectional screw 202 is fixedly connected to the output end of the drive motor 201. Both screw blocks 203 are threadedly connected to the front and rear sides of the surface of the bidirectional screw 202.

[0035] By setting up the unloading component 2, the output of the drive motor 201 causes the moving block 205 to drive the pallet 208 to lift and lower. By adjusting the height of the pallet 208, it is easy to lift the winding roller 104, avoiding the situation where the winding roller 104 falls to the ground when it is disassembled due to its large weight after winding. This ensures the convenience and safety of unloading when rewinding carbonless copy paper and makes it convenient for operators to use.

[0036] Example 2

[0037] like Figure 1-6 As shown, in one embodiment, a protective pad 209 is fixedly installed on the top of the support plate 208. The protective pad 209 is made of rubber. A movable groove 210 is provided on the right side of the top of the base plate 101. The bottom of the four movable blocks 205 are slidably connected to the inner cavity of the four movable blocks 205. A guide rod 211 is fixedly installed on the top of the base plate 101. Two screw blocks 203 are slidably connected to the front and rear sides of the surface of the guide rod 211. Anchor bolts 109 are threadedly connected to the left and right sides of the top of the base plate 101. The bottom of the four anchor bolts 109 are threadedly connected to the ground.

[0038] By setting the protective pad 209, damage to the carbonless copy paper wound on the surface of the take-up roller 104 can be avoided when the pallet 208 lifts the take-up roller 104. By setting the moving groove 210, the movement of the moving block 205 can be limited to prevent it from deviating during movement, which would affect the unloading of the carbonless copy paper wound on the take-up roller 104. By setting the guide rod 211, the movement of the screw block 203 can be limited to prevent the screw block 203 from rotating synchronously with the bidirectional screw 202. By setting the anchor bolts 109, the overall equipment can be stabilized to prevent the equipment from shaking due to accidental collisions.

[0039] In operation, the carbonless copy paper passes through the inner sides of the two guide rollers 102, and after passing the bottom of the tension roller 103, it wraps around the surface of the take-up roller 104. Through the output of the rotary motor 107, the second flange 106 synchronously drives the take-up roller 104 to rotate, thus completing the rewinding of the carbonless copy paper. After rewinding, through the output of the drive motor 201, the bidirectional screw 202 rotates, causing the screw block 203 to move outward. Simultaneously, the screw block 203 drives the mounting rod 204 and the moving block 205 to move outward. The moving block 205 cooperates with the connecting rod 206, which in turn drives the U-shaped plate 207 to move upward. Simultaneously, the U-shaped plate 207... The pallet 208 is moved upward, and the top of the pallet 208 contacts the bottom of the take-up roller 104 wrapped with carbonless copy paper. Then, the fixing bolt 108 is tightened to disconnect the take-up roller 104 from the second flange 106 and the first flange 105. Then, through the reverse output of the drive motor 201, the bidirectional screw 202 drives the screw block 203 to move inward. At this time, the mounting rod 204 and the moving block 205 move inward synchronously. The moving block 205 cooperates with the connecting rod 206, so that the connecting rod 206 drives the U-shaped plate 207, the pallet 208 and the take-up roller 104 wrapped with carbonless copy paper to move downward synchronously, thereby completing the unloading of the take-up roller 104 after the carbonless copy paper is wound.

[0040] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
