Description

Technical Field

[0001] This utility model relates to the field of blackboard shaker technology, specifically a blackboard shaker that is easy to install and disassemble. Background Technology

[0002] A blackboard shaking machine is a testing instrument used to shake cotton yarn, chemical fiber, and various blended yarns for inspecting and evaluating the appearance quality of the yarn. Currently, when the blackboard shaking machine is used for winding, the worker first winds the yarn on the bobbin onto the blackboard, and then the blackboard is rotated by a servo motor. The rotating blackboard will wind the remaining yarn on the bobbin onto the blackboard. At the same time, the transmission device makes the bobbin move horizontally, so that the yarn can be wrapped all over the blackboard. For example, a blackboard shaking machine that is easy to install and disassemble is described in application number 202021116345.0.

[0003] Traditional blackboard shakers have a limited range of motion between the clamping plates on both sides when installing a blackboard. This means that the shaker can only hold blackboards of a fixed size. When the size of the blackboard changes, the clamping plates on both sides cannot hold the new size blackboard, which limits the usable size of the blackboard. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a blackboard shaker that is easy to install and disassemble. It solves the problem that in traditional blackboard shakers, the movement distance of the clamping plates on both sides of the shaker is too small, which limits the size of the blackboard to be clamped. When the size of the blackboard changes, the clamping plates on both sides of the shaker cannot clamp the new size blackboard, thus limiting the usable size of the blackboard.

[0010] Beneficial effects

[0019] 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.

[0020] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0021] When installing a blackboard, the traditional blackboard shaker has a very small range of motion between the clamping plates on both sides, which means that the blackboard shaker can only hold blackboards of a fixed size. When the size of the blackboard changes, the clamping plates on both sides of the blackboard shaker cannot hold the new size blackboard, which limits the size of the blackboard that can be used.

[0022] In view of this, the present invention provides a blackboard shaker that is easy to install and disassemble. By changing the clamping mechanism in the device, the worker can adjust the distance between the two clamping plates of the blackboard shaker according to the size of the blackboard. In this way, when the size of the blackboard used changes, the worker can adjust the clamping distance between the two clamping plates according to the size of the blackboard, thereby meeting more usage scenarios. Moreover, it is convenient to use and simple to operate, which can improve the efficiency of installation and disassembly.

[0023] Example 1: By Figure 1 , 2 As shown in points 3 and 5, a blackboard shaker that is easy to install and disassemble includes a base 1, a replacement device 2 is provided on the top of the base 1, and a controller 6 is provided on one side of the base 1. The replacement device 2 includes: a first support plate 21, which is fixedly connected to the top of the base 1 on the side away from the controller 6; a first clamping plate 22, which is rotatably connected to the upper inner wall of the first support plate 21 via a bearing; a blackboard 24, which is pressed against the outer wall of the first clamping plate 22 on the side near the first support plate 21; multiple grooves 25, which are respectively machined on both sides of the blackboard 24; two first limiting blocks 23, which are both fixedly connected to the outer wall of the first clamping plate 22 on the side away from the first support plate 21, and the two first limiting blocks 23 are inserted into the groove 25 on the side of the blackboard 24 near the first support plate 21; and a clamping mechanism 26, which is provided on the top of the base 1 on the side near the controller 6. The first support plate 21 limits the blackboard 24 through the two first limiting blocks 23 of the first clamping plate 22, and then the clamping mechanism 26 fixes the blackboard 24.

[0024] In the specific implementation process, it is worth noting that the model of controller 6 is not limited, as long as it meets the usage requirements. Workers need to add lubricating oil to the bearing inside the first support plate 21 regularly to avoid the lack of oil affecting the rotation of the first clamping plate 22 along the inner wall of the first support plate 21 via the bearing. The blackboard 24 has a winding groove processed on the upper side near the first support plate 21. Workers can manually wind the end of the yarn into the winding groove of the blackboard 24 through the winding groove.

[0025] Furthermore, the clamping mechanism 26 includes: a limiting plate 261, fixedly connected to the top of the base 1 near the controller 6; a second support plate 262, slidably engaged with the inner wall of the limiting plate 261; a second clamping plate 263, rotatably connected to the upper inner wall of the second support plate 262 via bearings, and abutting against the outer wall of the blackboard 24 near the second support plate 262; two second limiting blocks 264, both fixedly connected to the outer wall of the second clamping plate 263 near the blackboard 24, and respectively engaged with the groove 25 of the second clamping plate 263 near the second support plate 262; and an electric push rod 265, fixedly connected to the top of the limiting plate 261 by bolts, and its output end fixedly connected to the lower outer wall of the second support plate 262; wherein, the electric push rod 265 drives the second support plate 262 to move along the inner wall of the limiting plate 261, thereby driving the second clamping plate 263 and the second limiting blocks 264 to move;

[0026] In the specific implementation process, it is worth noting that the electric push rod 265 is model TG-700. When the first clamping plate 22 is subjected to force to drive the blackboard 24 to rotate, the blackboard 24 will simultaneously drive the second clamping plate 263 to rotate along the inner wall of the second support plate 262 through the bearing. Since the two first limiting blocks 23 are inserted into the two grooves 25 on the side of the blackboard 24 near the first clamping plate 22, and the two second limiting blocks 264 are inserted into the two grooves 25 on the side of the blackboard 24 near the controller 6, the two first limiting blocks 23 and the two second limiting blocks 264 will limit the operation of the blackboard 24. This can prevent the blackboard 24 from being separated from the first clamping plate 22 and the second clamping plate 263 due to centrifugal force when rotating.

[0027] Specifically, when using this easy-to-install and disassemble blackboard shaker, before the blackboard shaker performs the wire winding operation, the worker first inserts one side of the blackboard 24 into the inner wall of the first clamping plate 22 until the two grooves 25 on the side of the blackboard 24 near the first support plate 21 engage with the two first limiting blocks 23, thus completing the fixing operation on one side of the blackboard 24. Then, the worker controls the output end of the electric push rod 265 to retract through the controller 6. When the output end of the electric push rod 265 retracts, it will drive the second support plate 262 to move along the inner wall of the limiting plate 261 away from the controller 6. When the second support plate 262 moves, it will drive the second clamping plate 263 and the two second limiting blocks 264 to move simultaneously until the second When the clamping plate 263 is fitted onto the outer wall of the blackboard 24, and the two second limiting blocks 264 are inserted into the two grooves 25 on the side of the blackboard 24 near the controller 6, the clamping and fixing operation of both sides of the blackboard 24 is completed. Subsequently, with the help of the transmission device 3, the yarn winding operation can be carried out. When the blackboard 24 needs to be replaced, the worker controls the output end of the electric push rod 265 through the controller 6 to extend the operation. The electric push rod 265 will drive the second support plate 262 to move towards the controller 6 until the second clamping plate 263 is detached from the outer wall of the blackboard 24. Then, the worker removes the side of the blackboard 24 near the first support plate 21 from the inner wall of the first clamping plate 22, and the blackboard 24 can be replaced.

[0028] Example 2: From Figure 1 , 2 As can be seen from points 3 and 4, a transmission device 3 is provided above the base 1. The transmission device 3 includes: two third support plates 31, which are respectively fixedly connected to the top two sides of the base 1, and the third support plate 31 near the electric push rod 265 is fixedly connected to the outer wall of the controller 6; a servo motor 32, which is fixedly connected to the upper part of the outer wall of the third support plate 31 near the controller 6 by bolts; and a reciprocating lead screw 33, whose two ends are respectively rotatably connected to the upper part of the inner wall of the two third support plates 31 through bearings, and the end near the controller 6. The output end of the servo motor 32 is fixedly connected; the slider 34 is threadedly connected to the side of the reciprocating screw 33 away from the servo motor 32; the drive wheel 35 is fixedly connected to the end of the reciprocating screw 33 near the slider 34; the belt 36 is installed on the outer wall of the drive wheel 35; the driven wheel 37 is fixedly connected to one end of the first clamping plate 22 and is in contact with the belt 36; wherein, the servo motor 32 drives the reciprocating screw 33 to move the slider 34, and at the same time drives the drive wheel 35 to drive the driven wheel 37 to rotate through the belt 36;

[0029] In the specific implementation process, it is worth noting that the model of the servo motor 32 is ECMA-E11320RS. The drive wheel 35 and the driven wheel 37 are each equipped with three gears. The worker can change the speed ratio between the drive wheel 35 and the driven wheel 37 by changing the gear of the belt 36. The drive wheel 35, the driven wheel 37 and the belt 36 are all equipped with corresponding teeth. In this way, when the drive wheel 35 is rotated under force, the drive wheel 35 can drive the driven wheel 37 to move synchronously through the belt 36. The speed of the slider 34 moving along the outer wall of the reciprocating screw 33 matches the speed of the blackboard 24. This can avoid the movement speed of the slider 34 being inconsistent with the speed of the blackboard 24, thus affecting the winding operation of the blackboard shaking machine.

[0030] Specifically, based on the above embodiment one, the worker first places the bobbin on the auxiliary device 4, then manually winds the end of the yarn on the bobbin into the winding groove of the blackboard 24. Next, the controller 6 controls the output end of the servo motor 32 to rotate. When the output end of the servo motor 32 rotates, it drives the reciprocating screw 33 to rotate synchronously along the inner wall of the two third support plates 31 through the bearing. At this time, the slider 34 is affected by the rotation of the reciprocating screw 33 and begins to move along the outer wall of the reciprocating screw 33 towards the side closer to the controller 6. When the reciprocating screw 33 rotates, it also drives the drive wheel 35 to rotate simultaneously. When the belt 36 moves along the outer wall of the drive wheel 35, the driven wheel 37 is affected by the movement of the belt 36 and begins to rotate synchronously with the drive wheel 35 along the inner wall of the first support plate 21 through the bearing. When the driven wheel 37 rotates, it will drive the first clamping plate 22 to rotate at the same time. The rotation of the first clamping plate 22 will drive the blackboard 24 to rotate. The rotating blackboard 24 will wrap the yarn around the outer wall of the blackboard 24. Because the slider 34 will drive the bobbin on the auxiliary device 4 to move at the same time when it moves along the outer wall of the reciprocating screw 33, the moving slider 34 will wrap the yarn on the bobbin all over the outer wall of the blackboard 24.

[0031] Example 3: From Figure 1 , 2 As shown in Figure 5, the outer wall of the slider 34 is provided with an auxiliary device 4, which includes: a vertical plate 41, fixedly connected to the top of the slider 34; a threading hole 42, machined above the vertical plate 41; a horizontal plate 43, fixedly connected to the front of the outer wall of the slider 34; two arc-shaped grooves 44, respectively machined on the top two sides of the horizontal plate 43; a limiting rod 45, fixedly connected to the top of the vertical plate 41; a counterweight 46, sleeved on the outer wall of the limiting rod 45, with its bottom fitting against the top of the horizontal plate 43; a support 47, fixedly connected to the bottom of the slider 34; and a vertical rod 48, fixedly connected to the lower outer wall of the support 47. The vertical plate 41 guides the yarn through the threading hole 42, the counterweight 46 prevents the yarn from shifting when moving in the arc-shaped groove 44 inside the horizontal plate 43, and the bobbin can be inserted into the vertical rod 48 on the outer wall of the support 47.

[0032] In the specific implementation process, it is worth noting that the inner wall of the counterweight 46 is equipped with a friction pad. When the yarn is wound, the counterweight 46 will be subjected to the tension of the yarn. The friction pad can increase the friction between the inner wall of the counterweight 46 and the outer wall of the limiting rod 45, thus preventing the yarn from coming off the arc groove 44 of the horizontal plate 43.

[0033] Specifically, based on the above embodiment one, after the blackboard 24 is installed, the worker first puts the yarn spool on the outer wall of the vertical rod 48. At this time, the support 47 will support the yarn spool. Then the worker removes the end of the yarn from the yarn spool and lifts the counterweight 46 upward. The counterweight 46 is under force and begins to move along the outer wall of the limiting rod 45 until the bottom of the counterweight 46 separates from the top of the horizontal plate 43. Then the worker puts a part of the yarn into the inside of an arc-shaped groove 44. Then the worker puts down the counterweight 46. At this time, the counterweight 46 will limit the yarn inside the arc-shaped groove 44, so that the yarn can only move inside the arc-shaped groove 44. This can prevent the yarn from deviating when it moves. Then the worker passes the end of the yarn through the threading hole 42 above the vertical plate 41. Finally, the worker winds the end of the yarn into the winding groove of the blackboard 24.

[0034] Example 4: From Figure 1 and 2 It is known that a limiting device 5 is provided below the auxiliary device 4. The limiting device 5 includes: a sleeve 51, which is fixedly connected to the bottom of the support 47; and a crossbar 52, which is fixedly connected to the lower side of the two third support plates 31 that are close to each other, and is in contact with the inner wall of the sleeve 51. When the sleeve 51 is subjected to force, it will slide along the outer wall of the crossbar 52.

[0035] In the specific implementation process, it is worth noting that when the slider 34 drives the support 47 and the sleeve 51 to move, the crossbar 52 will restrict the sleeve 51 to move only in the horizontal direction.

[0036] Specifically, based on the above embodiment 1, when the servo motor 32 drives the reciprocating screw 33 to rotate, the slider 34 will be subjected to force and move along the outer wall of the reciprocating screw 33. At this time, the support 47 and the sleeve 51 will move simultaneously with the slider 34. At this time, the crossbar 52 will limit the sleeve 51, so that the slider 34 can only move in the horizontal direction.

[0037] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, the phrase "comprising an element defined as..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0038] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "setting", "connection", "fixing", "screw connection", etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or the interaction between two components. Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
