DETAILED DESCRIPTION

[0018] The utility model is further described in detail below through specific implementation methods:

[0019] Because the rewinding roller 2 needs to be dragged by the staff during the disassembly process, the rewinding roller 2 can be safely disassembled. In order to solve this problem, Figure 1 , Figure 2 as well as Figure 4 As shown, an embodiment of the utility model proposes a rewinding machine for labor-saving disassembly and assembly, comprising a support frame 1 and a rewinding roller 2 installed in the support frame 1, and also comprising an adjustable support assembly 3 slidably arranged in the support frame 1 along the vertical direction and used to support the rewinding roller 2 during disassembly and assembly, the adjustable support assembly 3 comprises a transmission plate 31 and a support plate 32, wherein the transmission plate 31 is slidably arranged in the support frame 1 along the vertical direction and is located below the rewinding roller 2, and the transmission plate 31 is connected to an adjustment part for adjusting its sliding; there are two support plates 32, the two support plates 32 are arranged at intervals and are connected to the transmission plate 31 by a connecting rod 62, and the tops of the two support plates 32 are formed with arc-shaped support surfaces for abutting against the bottom of the rewinding roller 2.

[0020] During the disassembly and assembly process of the rewinding roller 2 in the labor-saving rewinding machine, the transmission plate 31 is made to slide upward in the support frame 1 through the adjustment part until the arc-shaped supporting surfaces of the two supporting plates 32 abut against the bottom of the rewinding roller 2. At this time, the rewinding roller 2 can be installed and disassembled, reducing the workload of the staff.

[0021] After the rewinding roller 2 is installed, the driving plate 31 is slid downward in the support frame 1 through the adjusting part until the two support plates 32 move to the lowest point, so as to prevent the two support plates 32 from obstructing the rewinding process of the rewinding roller 2.

[0022] In order to better understand this solution, the structure of the adjustment part and the like will be further optimized below.

[0023] like Figure 1 , Figure 2 as well as Figure 4 As shown, according to another embodiment of the utility model, a rewinding machine with labor-saving assembly and disassembly, wherein the adjusting part includes a guide rod 33 and a driving screw rod 34, the guide rod 33 is arranged in a vertical direction in the support frame 1, and the guide rod 33 is slidingly connected to the transmission plate 31; the driving screw rod 34 is in the support frame 1 and is arranged parallel to the guide rod 33, and the driving screw rod 34 is threadedly connected to the transmission plate 31.

[0024] When the rewinding roller 2 needs to be disassembled, the driving screw 34 is rotated, and the transmission plate 31 slides upward in the support frame 1 through the cooperation of the guide rod 33 until the arc-shaped supporting surfaces of the two support plates 32 abut against the bottom of the rewinding roller 2, and then the rewinding roller 2 can be disassembled. After the rewinding roller 2 is disassembled, the driving screw 34 is rotated in the opposite direction to return the transmission plate 31 to the initial position.

[0025] The above-mentioned adjustment part also includes a top mounted limit block 35 and a bottom mounted limit block 36, the top mounted limit block 35 is rotatably connected to the top end of the guide rod 33 and the driving screw rod 34, and the top mounted limit blocks 35 are fixedly connected to the support frame 1, and the two top mounted limit blocks 35 are located at the same height; the bottom mounted limit block 36 is rotatably connected to the lower end of the guide rod 33 and the driving screw rod 34, and the bottom mounted limit blocks 36 are fixedly connected to the support frame 1, and the two bottom mounted limit blocks 36 are located at the same height; when the transmission plate 31 abuts against the top mounted limit block 35, the arc-shaped support surface just abuts against the bottom of the rewinding roller 2.

[0026] That is, the guide rod 33 and the driving screw rod 34 are both equipped with a top-mounted limit block 35 and a bottom-mounted limit block 36. The cooperation of the top-mounted limit block 35 and the bottom-mounted limit block 36 can stably support the guide rod 33 or the driving screw rod 34 on the one hand, and limit the movement of the transmission plate 31 on the other hand, so that the support plate 32 can accurately support the rewinding roller 2. Specifically, the driving screw rod 34 is rotated, and when the transmission plate 31 moves upward to abut against the top-mounted limit block 35, the arc-shaped support surface just abuts against the bottom of the rewinding roller 2, and the two support plates 32 cooperate to support the rewinding roller 2; the driving screw rod 34 is rotated, and when the transmission plate 31 moves downward to abut against the bottom-mounted limit block 36, there is a sufficient distance between the support plate 32 and the installed rewinding roller 2, and the rewinding work of the rewinding roller 2 will not be hindered.

[0027] The lower end of the driving screw rod 34 can be connected to a hand wheel or a motor to manually or electrically control the rotation of the driving screw rod 34 .

[0028] like Figure 1-Figure 4 As shown, according to another embodiment of the utility model, a rewinding machine with labor-saving assembly and disassembly, wherein both ends of the rewinding roller 2 have a first connecting shaft 4, two second connecting shafts 5 are rotatably arranged in the support frame 1, the two first connecting shafts 4 correspond to the two second connecting shafts 5 one by one, and a transmission shaft 6 is arranged between the matching first connecting shafts 4 and the second connecting shafts 5, and a spacing adjustment structure 7 is arranged between the two transmission shafts 6, and the spacing adjustment structure 7 is used to drive the two transmission shafts 6 to move toward or away from each other to control the two transmission shafts 6 to be connected or disconnected from the corresponding first connecting shafts 4.

[0029] When installing the rewinding roller 2, the driving screw rod 34 is rotated to make the transmission plate 31 move upward until it is against the top installation limit block 35, and the rewinding roller 2 is placed on the top of the two support plates 32; then the two transmission shafts 6 are moved toward each other through the interval adjustment structure 7, and the two transmission shafts 6 are respectively connected to the corresponding first connecting shaft 4 and the second connecting shaft 5, and the installation of the rewinding roller 2 is completed; then the driving screw rod 34 is rotated in the opposite direction to make the transmission plate 31 move downward until it is against the bottom installation limit block 36, and the rewinding roller 2 can be rotated to perform the rewinding work; specifically in the present embodiment, one of the second connecting shafts 5 is connected to a driver fixed to the outside of the support frame 1 to drive the rotation, thereby driving the rewinding roller 2 to rotate to perform the rewinding work; the driver can be a motor.

[0030] When the rewinding roller 2 is disassembled, the driving screw 34 is rotated to move the transmission plate 31 upward until it is against the top installation limit block 35. At this time, the two support plates 32 are supported at the bottom of the rewinding roller 2; then the two transmission shafts 6 are moved apart through the interval adjustment structure 7, and the two transmission shafts 6 are disconnected from the corresponding first connecting shaft 4 and only remain connected to the corresponding second connecting shaft 5. At this time, the rewinding roller 2 can be removed from the two support plates 32.

[0031] Based on the above scheme:

[0032] The two transmission shafts 6 each include two transmission rods 61 that are arranged in parallel and at intervals. The two transmission rods 61 are connected by at least two connecting rods 62 that are arranged at intervals. One end of the two transmission rods 61 is equipped with a first connecting groove opened on the first connecting shaft 4, and the other end of the two transmission rods 61 is equipped with a second connecting groove opened on the second connecting shaft 5. The interval adjustment structure 7 is rotationally connected to the two transmission rods 61 in each transmission shaft 6.

[0033] When the interval adjustment structure 7 is used to move the two transmission shafts 6 toward each other, one end of the two transmission rods 61 in each transmission shaft 6 slides into the corresponding first connection groove, and the other end of the two transmission rods 61 in each transmission shaft 6 is kept in the corresponding second connection groove, so that the two transmission shafts 6 are both transmission-connected between the corresponding first connection shaft 4 and the second connection shaft 5 to complete the installation of the rewinding roller 2; because the interval adjustment structure 7 and the transmission rods 61 are both rotationally connected, the rewinding roller 2 will not be hindered by the interval adjustment structure 7 during the rewinding process. When the interval adjustment structure 7 is used to move the two transmission shafts 6 away from each other, one end of the two transmission rods 61 in each transmission shaft 6 withdraws from the corresponding first connection groove, and the other end of the two transmission rods 61 in each transmission shaft 6 is kept in the corresponding second connection groove, so that the two transmission shafts 6 are disconnected between the corresponding first connection shaft 4 and the second connection shaft 5.

[0034] In this embodiment:

[0035] There are two connecting rods 62 and when the two connecting rods 62 abut against the first connecting shaft 4 or the second connecting shaft 5, one end of the two transmission rods 61 just completely slides into the corresponding first connecting groove or completely withdraws from the corresponding first connecting groove. When the interval adjustment structure 7 makes the two transmission shafts 6 move toward each other until one of the connecting rods 62 abuts against the corresponding first connecting shaft 4, at this time, one end of the two transmission rods 61 in each transmission shaft 6 just slides into the corresponding first connecting groove for adaptation, and the other end of the two transmission rods 61 in each transmission shaft 6 remains in the corresponding second connecting groove, so that the two transmission shafts 6 are both connected between the corresponding first connecting shaft 4 and the second connecting shaft 5 to complete the installation of the rewinding roller 2; when the interval adjustment structure 7 makes the two transmission shafts 6 move away from each other until the other connecting rod 62 abuts against the corresponding second connecting shaft 5, one end of the two transmission rods 61 in each transmission shaft 6 completely withdraws from the corresponding first connecting groove; ensuring the accuracy of the interval adjustment structure 7 in controlling the movement of the transmission shaft 6 to connect or disconnect.

[0036] like Figure 1 , Figure 2 as well as Figure 4 As shown, according to another embodiment of the utility model, a rewinding machine with labor-saving assembly and disassembly, wherein the interval adjustment structure 7 includes an adjusting screw 71, and the adjusting screw 71 is arranged to rotate along the length direction of the rewinding roller 2, and two adjusting rods 72 are threadedly connected to the adjusting rod 72, and the two adjusting rods 72 are connected to a connecting sleeve 73, and the two connecting sleeves 73 are rotatably sleeved on the outside of the two transmission rods 61 in the two transmission shafts 6 in a one-to-one manner and limited along the axial direction of the transmission rod 61.

[0037] In this embodiment, two mounting blocks arranged opposite to each other are connected to the top of the support frame 1, and the adjusting screw 71 is rotatably connected between the two mounting blocks to stably install the adjusting screw 71. The adjusting screw 71 is rotated to make the two adjusting rods 72 move toward or away from each other, and then the two connecting sleeves 73 move toward or away from each other, thereby driving the two transmission shafts 6 to move toward or away from each other to control the connection state of the two first connection shafts 4. Each connecting sleeve 73 is rotatably sleeved on the outside of the two transmission rods 61 in the corresponding transmission shaft 6 and limited along the axial direction of the transmission rod 61, so that the connecting sleeve 73 drives the corresponding transmission shaft 6 to move to connect or disconnect with the matching first connection shaft 4, and the transmission shaft 6 will not be restricted by the connecting sleeve 73 during the rotation process.

[0038] Specifically, the two transmission rods 61 in each of the transmission shafts 6 form a limiting groove, the two limiting grooves are arranged in a circle and the corresponding inner side of the connecting sleeve 73 is rotationally limited in the two limiting grooves.

[0039] One end of the adjusting screw 71 is also connected to a handle or a motor for manual or electric driving and rotation.

[0040] When the rewinding roller 2 is being installed, the driving screw 34 is rotated to move the transmission plate 31 upward until it abuts against the top installation limit block 35, and the rewinding roller 2 is placed on the top of the two support plates 32; then the two transmission shafts 6 are moved toward each other by rotating the adjusting screw 71 until one of the connecting rods 62 abuts against the corresponding first connecting shaft 4, and at this time, one end of the two transmission rods 61 in each transmission shaft 6 just slides into the corresponding first connecting groove for adaptation, and the other end of the two transmission rods 61 in each transmission shaft 6 is kept in the corresponding second connecting groove, so that the two transmission shafts 6 are both transmission-connected between the corresponding first connecting shaft 4 and the second connecting shaft 5, to complete the installation of the rewinding roller 2 (such as Figure 1 ); then reversely rotate the drive screw 34 to move the transmission plate 31 downward to abut against the bottom mounting stop block 36 (such as Figure 2 ), at this time the rewinding roller 2 can rotate to perform the rewinding work.

[0041] When the rewinding roller 2 is disassembled, the driving screw 34 is rotated to move the transmission plate 31 upward until it abuts against the top mounting limit block 35. At this time, the two support plates 32 are supported at the bottom of the rewinding roller 2. Then, the two transmission shafts 6 are moved away from each other by rotating the adjusting screw 71 until the other connecting rod 62 abuts against the corresponding second connecting shaft 5, and one end of the two transmission rods 61 in each transmission shaft 6 is completely withdrawn from the corresponding first connecting groove (such as Figure 4 ), at this time, the rewinding roller 2 can be moved out from the two supporting plates 32.

[0042] In this solution, the two support plates 32 support the rewinding roller 2 in a one-to-one correspondence at the bottom of the two first connecting shafts 4 to prevent the two support plates 32 from squeezing the rewound paper on the rewinding roller 2 and causing damage when the paper is disassembled.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
