DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1 and 2 In the embodiment proposed in the present application, a metal calendering machine for facilitating replacement of calendering rollers is provided, comprising a gantry 1, a support frame 11 is fixedly arranged at the lower side of the gantry 1, a first calendering roller 2 and a second calendering roller 3 are transversely arranged in the middle of the gantry 1, and are respectively inserted at the left and right sides of the gantry 1, the first calendering roller 2 is located on the upper side of the second calendering roller 3, and a placement groove 12 is respectively opened horizontally and longitudinally at the front side of the gantry 1 corresponding to the insertion position of the first calendering roller 2 and the second calendering roller 3, and the placement groove 12 corresponds to the insertion position thereof. A driving block 4 with an opening forward is respectively provided, the driving block 4 is connected to the external driving device, and the corresponding driving block 4 is connected to the first calendering roller 2 and the second calendering roller 3 at the corresponding insertion positions. Limiting rods 5 are respectively provided laterally at the insertion positions of the first calendering roller 2 and the second calendering roller 3 on the left and right sides outside the gantry 1. The limiting rods 5 are rotatably connected to the gantry 1 and are threadedly connected to the insertion positions of the first calendering roller 2 and the second calendering roller 3. An adjusting structure 6 is provided on the upper side of the gantry 1 corresponding to the first calendering roller 2.

[0020] By setting the limiting plug rod 5, the lateral movement of the calendering roller is limited after installation, and the longitudinal movement is limited by cooperating with the driving block 4 with the opening forward, so that the calendering roller is stably fixed on the driving block 4. At the same time, the limiting plug rod 5 is rotatably connected with the gantry 1, which will not affect the rotation of the calendering roller. When disassembling the first calendering roller 2 and the second calendering roller 3, the limiting plug rod 5 is screwed out and the plug-in plate 8 is pushed upward to open the placement slot 12, so that the corresponding calendering roller can be removed from the driving block 4 in the placement slot 12, which is convenient and quick. At the same time, an adjustment structure 6 is provided to adjust the distance between the two calendering rollers so that it can perform calendering work according to different processes, which is convenient to adjust and highly practical.

[0021] The description of the setting of the drive block 4 and its driving connection with the external driving device is simplified here. It is a relatively well-known setting method in this field. A driving wheel for driving the calendering roller is provided in the drive block 4. The driving wheel is connected to the calendering roller after the calendering roller is inserted, and then the driving wheel is driven by the external driving device, thereby driving the calendering roller to rotate. Of course, the driving method here is not limited to the above method.

[0022] In another embodiment, see Figure 1 and 2 The adjusting structure 6 includes two connecting rods 61 respectively arranged vertically at the insertion position of the first calendering roller 2, the lower end of the connecting rod 61 passes through the gantry 1 and is fixedly connected to the top of the driving block 4, and an active cavity 13 is longitudinally opened in the gantry 1 corresponding to the driving block 4, and the driving block 4 can slide up and down in the active cavity 13, and a first active groove 14 is longitudinally opened at the insertion position corresponding to the first calendering roller 2, and the first calendering roller 2 can slide up and down in the first active groove 14 at the insertion position, and a second active groove 15 is longitudinally opened at the corresponding limit plug rod 5, and the limit plug rod 5 can slide up and down in the second active groove 15, and a fixed plate 62 is transversely arranged at the upper ends of the two connecting rods 61, and a driving structure 7 is arranged at the bottom of the fixed plate 62 corresponding to the top of the gantry 1, and the driving structure 7 includes a hydraulic cylinder, which is arranged at the top of the gantry 1, and the top of the driving end of the hydraulic cylinder is fixedly connected to the bottom of the fixed plate 62;

[0023] When calendering is performed in different processes, the required distance between the calendering rollers is also different. At this time, the hydraulic cylinder can be controlled to extend and retract through an external control device, thereby driving the fixed plate 62 to perform lifting and lowering movements, so that the connecting rod 61 fixedly connected to the fixed plate 62 can be driven to perform lifting and lowering movements, thereby adjusting the two driving blocks 4 and the first calendering roller 2 driven and connected thereto to perform lifting and lowering movements, thereby adjusting the distance between the first calendering roller 2 and the second calendering roller 3;

[0024] Here, when the driving block 4 is performing lifting motion, the driving block 4 and the external driving device can be fixedly connected. The external driving device here can be: a driving motor, which is fixed on the driving block 4, and its driving end is drivingly connected to the driving wheel of the driving block. Of course, this is not limited to this driving method and connection method.

[0025] The driving block 4 at the insertion point of the second calendering roller 3 is fixedly connected to the gantry 1. Since the distance between the first calendering roller 2 and the second calendering roller 3 can be adjusted by adjusting the first calendering roller 2, the second calendering roller 3 can be kept fixed at this time.

[0026] In another embodiment, see Figure 1 and 2A plug-in plate 8 is slidably provided at the front side of the gantry 1 at the corresponding placement groove 12, and a plug-in groove 16 is longitudinally opened at the front side of the gantry 1 at the corresponding placement groove 12 of the gantry 1. The plug-in plate 8 is inserted in the insertion groove 16 and slidably connected thereto, and a clearance hole 81 is opened at the placement groove 12 of the insertion position of the plug-in plate 8 corresponding to the first calendering roller 2;

[0027] The plug-in plate 8 here is an plug-in plate 8 that passes through the two placement slots 12. When the plug-in plate 8 is pushed downward, the clearance hole 81 will move into the plug-in slot 16, so that the plug-in plate 8 can block the two placement slots 12 at the same time to prevent debris from entering and affecting the operation of the machine. When disassembly is required, it is only necessary to push the plug-in plate 8 upward until the clearance hole 81 corresponds to the placement slot 12 at the first calendering roller 2. At this time, the two placement slots 12 are both in an open state, which is convenient for disassembly.
