Description

Technical Field

[0001] This utility model belongs to the field of filling equipment technology, and in particular relates to a capping gripper and filling machine for a filling machine used in the production of single-walled carbon nanotube slurry. Background Technology

[0002] In the production process of single-walled carbon nanotube slurry filling, different sizes of filling containers require specific capping sizes to achieve the sealing requirements. Filling containers are divided into internally threaded bottle necks (compatible with externally threaded caps) and externally threaded bottle necks (compatible with internally threaded caps). Traditional filling machine capping grippers can only be compatible with one type of cap. When the production line needs to switch filling container sizes, it must stop the machine to replace the capping gripper, which is not conducive to continuous production.

[0003] Therefore, how to solve the problem that the capping gripper of the filling machine for single-walled carbon nanotube slurry production cannot be adapted to both internal and external thread caps is a technical problem that urgently needs to be solved by those skilled in the art.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

[0005] This disclosure provides at least one capping gripper and filling machine for producing single-walled carbon nanotube slurry.

[0006] In a first aspect, embodiments of this disclosure provide a capping gripper for a filling machine used in the production of single-walled carbon nanotube slurry, comprising:

[0007] The connecting rod is hollow inside and equipped with a cylinder.

[0008] An adjusting component, which is connected to the cylinder via a piston rod;

[0009] Several connecting arms are circumferentially hinged to the lower edge of the connecting rod, and the adjusting member is located at the middle position of each of the connecting arms;

[0010] The same number of support arms as the connecting arms are hinged to the adjusting component and the connecting arms on their upper sides, respectively.

[0011] The cylinder is adapted to drive the adjusting component to move axially along the connecting rod;

[0012] When the adjusting member moves upward, it exerts a traction force on the hinge point of the support, causing the support to retract inward and engage with the outer wall of the internal threaded cap.

[0013] When the adjusting member moves downward, its lower edge presses against the guide slope of the gripper, causing the gripper to expand outward and support the inner wall of the external threaded cap.

[0014] In one alternative embodiment, the piston rod is fitted with a spring, one end of which abuts against the lower end face of the connecting rod, and the other end abuts against the upper end face of the adjusting member.

[0015] In one optional embodiment, the adjusting member is cylindrical with a plurality of hinge seats evenly distributed around its circumference, and the support is hinged to the adjusting member through the hinge seats.

[0016] In one optional embodiment, rubber pads are provided on both the inner and outer sides of the support, and the surface of the rubber pads is distributed with anti-slip textures.

[0017] In one alternative embodiment, the connecting arm is hinged to the lower end of the connecting rod by a pin, and the tail of the pin is provided with an anti-disengagement spring.

[0018] In one optional embodiment, when the support is retracted, the angle between the guide ramp and the lower end face of the adjusting member is in the range of 15-30°.

[0019] Secondly, this disclosure also provides a capping gripper for a filling machine, comprising:

[0020] Connecting rod;

[0021] The drive assembly is located inside the connecting rod;

[0022] An adjusting component, which is connected to the drive assembly via an axial transmission component;

[0023] Several connecting arms are circumferentially hinged to the lower edge of the connecting rod, and the adjusting member is located at the middle position of each of the connecting arms;

[0024] The same number of support arms as the connecting arms are hinged to the adjusting component and the connecting arms on their upper sides, respectively.

[0025] The drive assembly is adapted to drive the adjusting member to move axially along the connecting rod;

[0026] When the adjusting member moves upward, it exerts a traction force on the hinge point of the support, causing the support to retract inward and engage with the outer wall of the internal threaded cap.

[0027] When the adjusting member moves downward, its lower edge presses against the guide slope of the gripper, causing the gripper to expand outward and support the inner wall of the external threaded cap.

[0028] In one alternative embodiment, the drive assembly includes a cylinder, the connecting rod is hollow, and the cylinder is disposed inside the connecting rod.

[0029] In one alternative embodiment, the axial transmission component includes a piston rod, one end of which is connected to a cylinder and the other end of which is connected to an adjusting component.

[0030] Thirdly, this disclosure also provides a filling machine, including the aforementioned filling machine capping gripper.

[0031] The beneficial effect of this utility model is that the capping gripper of the filling machine for single-walled carbon nanotube slurry production can switch between two working modes—radially contracting and engaging the outer wall of the internal thread cap, and radially expanding and supporting the inner wall of the external thread cap—by controlling the lifting direction of the adjusting component. This achieves dual-purpose functionality and solves the problem of production line interruption caused by the inability of traditional grippers to simultaneously adapt to both internal and external thread caps when the production line needs to switch filling barrel specifications, requiring gripper replacement.

[0046] Research has revealed the drawbacks of existing technologies: traditional filling machine capping grippers can only be used with one type of cap. When the production line needs to switch filling barrel specifications, the machine must be stopped to replace the capping gripper, which is not conducive to continuous production.

[0047] Based on the above research, this disclosure provides a capping gripper for a filling machine used in the production of single-walled carbon nanotube slurry. The working mode of the gripper is switched by the axial movement of the adjusting member: when the adjusting member moves upward, it grips and holds the outer wall of the radially contracting internal thread cap; when the adjusting member moves downward, it grips and holds the radially expanding external thread cap, thus solving the above problems.

[0048] The shortcomings of the above solutions are the result of the inventor's practical experience and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as the inventor's contribution to this disclosure.

[0049] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0050] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0051] See Figure 1 This disclosure also provides a capping gripper for a filling machine used in the production of single-walled carbon nanotube slurry, comprising: a connecting rod 100, which is hollow and equipped with a cylinder 210. The cylinder 210 is connected to one end of a piston rod 410, and the other end of the piston rod 410 is connected to an adjusting member 300. Through the piston rod 410, the cylinder 210 can drive the adjusting member 300 to move axially along the connecting rod 100.

[0052] See Figure 1 and Figure 2 Several connecting arms 500 are hinged to the lower end of the connecting rod 100. The connecting arms 500 are symmetrically hinged circumferentially to the lower edge of the connecting rod 100. The adjusting member 300 is located in the middle of each connecting arm 500. A support 600 is hinged to the lower end of each connecting arm 500. One side of the upper end of the support 600 is hinged to the adjusting member 300, and the other side is hinged to the connecting arm 500. When the cylinder 210 drives the adjusting member 300 to move upward, as... Figure 2 As indicated by the arrow, the adjusting member 300, through traction, acts on the hinge point 610 of the support 600, converting the axial force F1 into a radial contraction force F2, thereby causing the support 600 to retract inward and engage the outer wall of the internal threaded cap 900. When the cylinder 210 drives the adjusting member 300 to move downward, as... Figure 1 As indicated by the arrow, the lower edge of the adjusting component 300 presses against the guide slope 620 of the gripper 600, converting the axial force F1 into a radial expansion force F2. This causes the gripper 600 to expand outward, supporting the inner wall of the external thread cap 800. With this configuration, by simply controlling the lifting direction of the adjusting component 300, the gripper 600 can switch between two working modes: radially contracting to engage the outer wall of the internal thread cap 900 and radially expanding to support the inner wall of the external thread cap 800. This achieves dual functionality and solves the problem of production line interruptions caused by the inability of traditional grippers to simultaneously adapt to both internal thread caps 900 and external thread caps 800 when the production line needs to switch filling barrel specifications, necessitating gripper replacement.

[0053] See Figure 2 In some embodiments, the piston rod 410 is fitted with a spring 700, one end of which abuts against the lower end face of the connecting rod 100, and the other end abuts against the upper end face of the adjusting member 300. During the upward movement of the adjusting member 300 driven by the cylinder 210, the spring 700 is compressed to store energy and absorb inertial impact, which helps to attenuate the instantaneous impact force of the gripper 600 engaging the cap, protecting the cap from damage.

[0054] See Figure 3In some embodiments, the adjusting member 300 is cylindrical, with a plurality of hinge seats 310 evenly distributed around its circumference. The support 600 is hinged to the adjusting member 300 through the hinge seats 310. The evenly distributed hinge seats 310 can ensure that the multiple support 600s move in unison, so that the forces of the support 600s engaging the outer wall of the internal threaded cap 900 or supporting the inner wall of the external threaded cap 800 are relatively balanced.

[0055] See Figure 1 In some embodiments, rubber pads 630 are provided on both the inner and outer sides of the gripper 600, and the surface of the rubber pads 630 is distributed with anti-slip textures. The anti-slip textures on the rubber pads 630 can significantly increase the coefficient of friction between the gripper 600 and the internal thread cap 900 or the external thread cap 800, making it easier to screw the cap on.

[0056] See Figure 3 In some embodiments, the connecting arm 500 is hinged to the lower end of the connecting rod 100 via a pin 510, and the tail of the pin 510 is provided with an anti-disengagement spring 520. When the connecting arm 500 needs maintenance, the connecting arm 500 can be removed simply by pulling out the spring at the tail of the pin 510, making the operation simple.

[0057] See Figure 1 In some embodiments, when the support 600 is in the retracted state, the angle formed between the guide slope 620 and the lower end face of the adjusting member 300 is in the range of 15-30°, preferably 25°. Within this angle range, when the adjusting member 300 moves downward, the radial expansion force it generates is moderate, so as to avoid excessive expansion force damaging the inner wall of the internal thread cap 900 or insufficient expansion force to support the inner wall of the internal thread cap 900.

[0058] See Figure 1 and Figure 2Some embodiments also provide a capping gripper for a filling machine, comprising: a connecting rod 100; a drive assembly 200 disposed inside the connecting rod 100; an adjusting member 300 connected to the drive assembly 200 via an axial transmission member 400; a plurality of connecting arms 500 circumferentially hinged to the lower edge of the connecting rod 100, with the adjusting member 300 located at the middle position of each connecting arm 500; and a support grip 600 having the same number as the connecting arms 500, with its upper sides respectively connected to the adjusting member 300 and the connecting arms 500. 0. Hinged; wherein, the driving assembly 200 is adapted to drive the adjusting member 300 to move axially along the connecting rod 100; when the adjusting member 300 moves upward, it acts on the hinge point 610 of the support (600) through traction, causing the support 600 to retract inward and engage the outer wall of the internal threaded cap 900; when the adjusting member 300 moves downward, its lower edge presses against the guide slope 620 of the support 600, causing the support 600 to expand outward and support the inner wall of the external threaded cap 800.

[0059] See Figure 1 In some embodiments, the drive assembly 200 includes a cylinder 210, and the connecting rod 100 is hollow inside, with the cylinder 210 disposed inside the connecting rod 100.

[0060] See also Figure 1 In some embodiments, the axial transmission member 400 includes a piston rod 410, one end of which is connected to the cylinder 210 and the other end of which is connected to the adjusting member 300.

[0061] Some embodiments also provide a filling machine including a capping gripper using the filling machine described in the above embodiments.

[0062] In summary, the capping gripper of this single-walled carbon nanotube slurry production filling machine can switch between two working modes—radially contracting and engaging the outer wall of the internal thread cap 900 and radially expanding and supporting the inner wall of the external thread cap 800—by controlling the lifting direction of the adjusting component 300. This achieves dual functionality in one machine and solves the problem of production line interruption caused by the inability of traditional grippers to simultaneously adapt to both the internal thread cap 900 and the external thread cap 800 when the production line needs to switch filling barrel specifications, requiring gripper replacement.

[0063] In the description of the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0064] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence unless expressly indicated herein. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or segment discussed above may be referred to as the second element, component, region, layer, or segment.

[0065] Spatially relative terms, such as “inside,” “outside,” “below,” “below,” “down,” “above,” “up,” etc., may be used herein to describe the relationship between one element or feature illustrated in the figures and another element or feature. In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, an element described as “below” or “below” other elements or features would be oriented as “above” other elements or features. Thus, the example term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.

[0066] In the above discussion, unless otherwise stated, when used to describe numerical values, the terms “about,” “approximately,” “basically,” etc., indicate a change of + / - 10% in that value.

[0067] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
