Description

Technical Field

[0001] This utility model relates to the field of mechanical processing equipment technology, and in particular to an elastic squeeze roller. Background Technology

[0002] Flexible squeeze rollers are common key components in industrial production, widely used in steel, textile, papermaking, and circuit board manufacturing. Their main function is to use the pressure and elasticity of the rollers to squeeze the passing sheet or material to remove surface moisture or other liquids, ensuring the dryness and quality of subsequent processes.

[0003] During prolonged continuous operation, the roll portion of the elastic squeeze roller will wear, age, or be damaged due to continuous squeezing, friction, and contact with chemical liquids. To ensure squeezing effect and product quality, these rolls must be inspected, maintained, or replaced regularly.

[0004] Existing flexible squeeze rollers are typically designed with the rollers mounted within a sturdy frame consisting of an upper support frame and a lower support frame. To ensure rigidity and stability during operation, the upper and lower support frames are often secured and locked together using a large number of bolts.

[0005] When the rolls need to be replaced, maintenance personnel must disassemble numerous fastening bolts one by one to remove the upper support frame. This process is not only cumbersome and time-consuming, but also results in many disassembled parts that are easily lost. During reinstallation, each part must be tightened individually, making it difficult to guarantee a quick return to production and severely impacting overall production efficiency and ease of equipment maintenance.

[0006] Therefore, this utility model proposes an elastic squeeze roller to overcome the shortcomings of the prior art. Utility Model Content

[0007] To overcome the above shortcomings, this utility model provides an elastic squeeze roller, which aims to improve the problem of cumbersome and time-consuming disassembly and maintenance of the roller components in some existing elastic squeeze rollers.

[0008] This utility model provides an elastic squeeze roller, including a lower support frame, an upper support frame, a roller rotatably mounted between the lower support frame and the upper support frame, and a quick-release mechanism.

[0009] The quick-release mechanism is used to detachably connect the upper support frame and the lower support frame. The quick-release mechanism mainly includes a cylinder, a sliding block, a connecting arm, a top frame, and a locking block.

[0010] The cylinder is located inside the lower support frame, and its output end drives the sliding block to move vertically. The inner wall of the sliding block is rotatably connected to one end of a connecting arm, which acts as a transmission component, converting the linear motion of the sliding block into the unlocking motion of the locking block. The top frame is fixedly installed on the top of the lower support frame, providing guidance and limiting for the movement of the locking block. The other end of the connecting arm is rotatably connected to the locking block, which slides against the inner wall of the top frame. The locking end of the locking block forms a separable locking engagement with the upper support frame. Driven by the cylinder, the locking block can move under the guidance of the top frame, enabling rapid locking or unlocking of the upper support frame, greatly simplifying the roll changeover process.

[0011] Preferably, a limiting block is fixedly connected to the outer wall of the sliding block. The limiting block is disposed inside the lower support frame. The limiting block is used to limit the movement of the sliding block when it moves vertically, so as to prevent the sliding block from displacing excessively or deviating from the preset trajectory.

[0012] Preferably, a limiting block two is fixedly connected to the outer wall of the locking block, and the limiting block two is slidably fitted to the inner wall of the top frame. The limiting block two is used to limit the lateral movement of the locking block within the top frame, ensuring that the unlocking and locking actions of the locking block are accurate and stable.

[0013] Preferably, the elastic squeeze roller further includes a device base plate and a calibration rotation mechanism; the lower support frame is fixedly installed on the top of the device base plate, and the calibration rotation mechanism is fixedly installed on the top of the device base plate. The calibration rotation mechanism is provided with a structure that can be separably engaged with the roller, and the calibration rotation mechanism provides auxiliary docking, driving and positioning functions when the roller is disassembled and assembled.

[0014] Preferably, the calibration rotation mechanism includes a control device and a slider; the slider is fixedly connected to the bottom of the control device, and the slider slides against the inner wall of the device base plate. The slider allows the control device to move smoothly along the guide rail of the device base plate in the rolling direction, achieving rapid alignment.

[0015] Preferably, the calibration rotation mechanism further includes a motor; the motor is fixedly installed on the control device, and the motor serves as the power source for the entire calibration rotation mechanism, used to drive the meshing structure to rotate.

[0016] Preferably, the calibration rotation mechanism further includes a pin; the output shaft of the motor is fixedly connected to and drives the pin to rotate, and the pin serves as the output end of torque for connecting with the roller.

[0017] Preferably, the inner wall of the end face of the roll is provided with a slot; the end shape of the pin is adapted to the slot, the pin rotates and engages in the slot, and after the control device moves into place, the pin is inserted into the slot to form a stable rotational connection, thereby realizing the precise driving and positioning of the roll.

[0018] This utility model has the following beneficial effects:

[0019] 1. This utility model solves the problem of cumbersome and time-consuming disassembly and maintenance process of roll components in the prior art by setting a quick-release mechanism driven by a cylinder and linked by a sliding block and a connecting arm locking block. It achieves the technical effect of quickly separating and locking the upper support frame and the lower support frame, greatly simplifying the roll replacement process and improving maintenance efficiency.

[0020] 2. This utility model solves the problems of difficult docking and inaccurate positioning when changing rolls in the prior art by setting up a sliding control device and using a calibration rotation mechanism that uses a motor-driven pin to mesh with a slot opened on the roll. It achieves the technical effect of facilitating auxiliary docking, rotation and positioning of the roll during disassembly and assembly, reducing installation difficulty and ensuring installation accuracy.

[0021] 3. This utility model solves the problem of excessive travel or unstable trajectory of moving parts in the quick-release mechanism by setting limiting blocks on the outer wall of the sliding block and the outer wall of the locking block respectively. It achieves the technical effect of limiting the vertical movement of the sliding block and the lateral movement of the locking block respectively, ensuring the stability and accuracy of the quick-release action, and improving the reliability of the device.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example:

[0034] Reference Figures 1 to 5 This utility model provides an elastic squeeze roller, which aims to solve the structural defects in the prior art, such as cumbersome and time-consuming disassembly and maintenance process of roll components and difficulty in roll docking and positioning during replacement.

[0035] like Figure 1 and Figure 2 As shown, the device includes a base plate 1 and a lower support frame 2 fixedly installed on the top of the base plate 1. An upper support frame 3 is fitted onto the top of the lower support frame 2. The roller 4 is rotatably installed between the lower support frame 2 and the upper support frame 3. The base plate 1 serves as the load-bearing base of the entire device and is horizontally positioned on the working plane. The lower support frame 2 extends vertically upward and is fixedly connected to the upper surface of the base plate 1. The top of the lower support frame 2 has a support surface adapted to the contour of the roller 4. The upper support frame 3 is locked and covers the top of the lower support frame 2. The upper support frame 3 and the lower support frame 2 together form a rotating chamber for the installation of the roller 4. The journals at both ends of the roller 4 are restricted. Between the lower support frame 2 and the upper support frame 3, the roller 4 can rotate stably around its own axis under the constraint of the lower support frame 2 and the upper support frame 3. The upper support frame 3 and the lower support frame 2 adopt a split structure design. When the upper support frame 3 and the lower support frame 2 are in a closed connection state, the roller 4 is locked in the working position for extrusion operation. When the upper support frame 3 and the lower support frame 2 are separated, the constraint above the roller 4 is released, which makes it convenient for the staff to hoist, replace or repair the roller 4. The lower support frame 2 and the upper support frame 3 are integrated with quick-release functional components. At the same time, the device base plate 1 is also equipped with calibration components for assisting the installation and debugging of the roller 4.

[0036] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4The quick-release mechanism 5 is installed inside the lower support frame 2. The quick-release mechanism 5 includes a cylinder 51, a sliding block 52, a first limiting block 53, a connecting arm 54, a top frame 55, and a locking assembly 56. The locking assembly 56 includes a locking block 561 and a second limiting block 562. The cylinder 51 is located inside the lower support frame 2 or the upper support frame 3. The output end of the cylinder 51 drives the sliding block 52 to move vertically downwards. The outer wall of the sliding block 52 is fixedly connected to the first limiting block 53, which is located inside the lower support frame 2. The first limiting block 53 is used to limit the vertical movement stroke of the sliding block 52 to prevent excessive displacement of the sliding block 52. One end of the connecting arm 54 is rotatably connected to the inner wall of the sliding block 52. The top frame 55... The locking block 561 is fixedly installed on the top of the lower support frame 2. The top frame 55 defines the internal space for the movement of the locking block 561. The other end of the connecting arm 54 is rotatably connected to the locking block 561. The locking block 561 is slidably engaged with the inner wall of the top frame 55. The snap-fit ​​end of the locking block 561 forms a separable snap-fit ​​with the upper support frame 3. When the cylinder 51 drives the sliding block 52 to move, the locking block 561 is driven to slide in the top frame 55 through the transmission of the connecting arm 54, so as to lock or release the snap-fit ​​end of the locking block 561 against the upper support frame 3. The outer wall of the locking block 561 is fixedly connected to the second limiting block 562. The second limiting block 562 is slidably engaged with the inner wall of the top frame 55 to limit the lateral movement of the locking block 561.

[0037] Reference Figure 1 and Figure 5 The device also includes a calibration rotation mechanism 6; the calibration rotation mechanism 6 is fixedly installed on the top of the device base plate 1, and the calibration rotation mechanism 6 is provided with a structure that can be separably engaged with the roller 4, for docking or driving the roller 4 during disassembly and assembly. The calibration rotation mechanism 6 includes a control device 62 and a slider 61; the slider 61 is fixedly connected to the bottom of the control device 62 and slides against the inner wall of the device base plate 1, for realizing the translation of the control device 62 towards or away from the roller 4. The calibration rotation mechanism 6 also includes a motor 63; the motor 63 is fixedly installed on the control device 62, and the motor 63 is used to provide the rotation power source for the calibration rotation mechanism 6. The calibration rotation mechanism 6 also includes a pin 64; the output shaft of the motor 63 is fixedly connected to and drives the pin 64 to rotate.

[0038] Reference Figure 1 and Figure 5 The inner wall of the end face of the roller 4 is provided with a slot 65; the end shape of the pin 64 is adapted to the slot 65, the pin 64 rotates and engages in the slot 65 to form a rotatable connection for transmitting the power of the motor 63.

[0039] The implementation principle of this application embodiment is as follows: When it is necessary to disassemble and separate the lower support frame 2 and the upper support frame 3 to replace the roller 4, the cylinder 51 in the quick-release mechanism 5 is activated. The cylinder 51 drives the output end to move downward, and the cylinder 51 drives the sliding block 52 to move downward. The first limiting block 53 fixed to the outer wall of the sliding block 52 restricts the vertical movement of the sliding block 52 to prevent the sliding block 52 from displacing excessively. The sliding block 52 is driven by the inner wall rotating connection connecting arm 54. The connecting arm 54 pulls the other end rotating connection locking block 561 to slide on the inner wall of the top frame 55. The second limiting block 562 fixed to the outer wall of the locking block 561 slides on the inner wall of the top frame 55 and restricts the lateral movement trajectory of the locking block 561. As the locking block 561 moves, the end of the locking block 561 disengages from the upper support frame 3, releasing the locking and fixing of the upper support frame 3. At this time, the upper support frame 3 can be removed and the roller 4 can be taken out.

[0040] When it is necessary to align or assist in the installation of the roll 4, the control device 62 is pushed inward. The control device 62 is guided by the bottom fixed connecting slider 61 to slide on the inner wall of the device base plate 1, so that the control device 62 is close to the roll 4. Then the motor 63 is started, and the motor 63 drives the pin 64 to rotate. The pin 64 is aligned with and inserted into the slot 65 opened in the inner wall of the end face of the roll 4. The pin 64 engages with the slot 65, so that the motor 63 can control or position the rotation of the roll 4, and assist in the disassembly and assembly of the roll 4.
