Description

Technical Field

[0002] With the continuous development of social economy and the increasing improvement of scientific and technological levels, my country's chemical industry is also developing continuously. Stacking barrels, as equipment for storing and transporting chemical liquids, can package special hazardous liquids and play an important role in the chemical industry.

[0003] There is a stacking barrel in the prior art, which includes a barrel body, wherein the top wall of the barrel body at one end along its length direction is depressed downward to form a concave cavity, and the top of the concave cavity and the side end away from the other end of the barrel body in the length direction are both connected to the outside. A barrel neck is arranged in the concave cavity, and an anti-theft cover is arranged on the barrel neck, and the anti-theft cover is sealed on the barrel neck. An anti-theft ring is also arranged at the bottom end of the anti-theft cover, and a pull buckle is arranged on the outside of the anti-theft ring, and the pull buckle is located in the concave cavity. When in use, the user pulls the buckle, so that the pull buckle drives the anti-theft ring to move together, so that the anti-theft ring is separated from the bottom end of the anti-theft cover, which is convenient for the user to unscrew the anti-theft cover.

[0004] There is also a kind of capping device in the prior art, which includes a machine body, and a lifting frame and a lifting assembly are also provided on the machine body, and the lifting assembly is used to drive the lifting frame to lift. A clamping frame and a rotating mechanism are also provided on the top of the lifting frame, and the clamping frame is rotatably connected to the lifting frame, and the rotating mechanism is used to drive the clamping frame to rotate. A clamping frame and a driving mechanism are also provided on the clamping frame, and the clamping frame is provided in a plurality of clamping frames, and the plurality of clamping frames are all slidably connected to the clamping frame, and the driving mechanism is used to drive each clamping frame to lean against each other at the same time. When in use, the clamping frame clamps the anti-theft cover, and the lifting assembly drives the lifting frame to move downward, so that the anti-theft cover contacts the barrel neck opening on the top of the barrel body to be installed, and then the rotating mechanism drives the clamping frame to rotate, so that the anti-theft cover is screwed on the barrel body, and then the driving mechanism drives the clamping frame to loosen, and the installation between the anti-theft cover and the barrel body is completed.

[0005] With regard to the above-mentioned related technologies, since the buckle is located on the outside of the anti-theft ring, in order to reduce the probability of accidental wear of the buckle, it is necessary to make the buckle on the anti-theft cover completely located in the recessed cavity after tightening. However, the existing capping machine can only tighten the anti-theft cover, which makes it difficult to ensure that the buckle is located in the recessed cavity after tightening, thereby increasing the probability that the buckle on the anti-theft cover is located outside the recessed cavity after tightening, and further increasing the probability of accidental wear of the buckle, so it needs to be improved. Utility Model Content

[0006] In order to ensure that the pull tab on the anti-theft cover is completely located in the recessed cavity after being tightened, the present application provides a screw cover clamping device.

[0007] The present application provides a capping clamping device, which adopts the following technical solution:

[0008] A capping clamping device comprises a lifting frame, a clamping frame, a rotating mechanism, a driving mechanism and a plurality of clamping frames, wherein the lifting frame is used to be installed on a capping machine, the rotating mechanism is used to drive the clamping frame to rotate, a placement slot is provided on the bottom end of one of the clamping frames, the placement slot is used to place a pull tab on an anti-theft cover, and a control mechanism is also provided on the clamping frame provided with the placement slot, the control mechanism comprises a position detection component and a control component, the position detection component and the rotating mechanism are both controlled by the control component, the position detection component is used to detect whether the pull tab is located in a recessed cavity on a stacking barrel after being tightened, and the control component is used to control the opening and closing of the rotating mechanism based on the result detected by the position detection component.

[0009] By adopting the above technical scheme, compared with the prior art, it is difficult to control the position of the buckle after the anti-theft cover is tightened, and thus it is difficult to ensure that the buckle is located in the recessed cavity after tightening. The present application sets a control mechanism, so that after the clamping frame clamps the anti-theft cover, the buckle on the anti-theft cover is located in the placement groove, and then after the anti-theft cover is tightened, the position detection component is used to detect whether the buckle is located in the recessed cavity on the stacking barrel. When the position detection component detects that the buckle is completely located in the recessed cavity, the control component controls the rotating mechanism to close, so that the anti-theft cover maintains the current position, ensuring that the buckle is completely located in the recessed cavity, thereby reducing the probability of the buckle being located outside the recessed cavity after tightening, and further reducing the probability of accidental wear of the buckle.

[0010] Preferably, the driving mechanism includes a driving member and an abutment platform, the abutment platform is located in the clamping frame and is slidably connected to the clamping frame, the sliding direction of the abutment platform is the height direction of the clamping frame, and a guide surface is also provided on the side wall of the abutment platform, the top end of each of the clamping frames extends into the clamping frame and is slidably connected to the clamping frame, each of the clamping frames abuts against the guide surface on the abutment platform, and the driving member is used to drive the abutment platform to slide.

[0011] By adopting the above technical solution and the specific setting of the driving mechanism, when the anti-theft buckle needs to be clamped, the driving member drives the abutment table to slide, so that the guide surface on the abutment table continuously abuts against the clamping frame and pushes the clamping frame to slide outward, thereby realizing the opening of the clamping frame, so that relevant personnel can control all the clamping frames by only one driving member, which facilitates the operation of relevant personnel.

[0012] Preferably, each of the clamping frames is provided with an abutment spring, which is located inside the clamping frame and on the side of the corresponding clamping frame away from the abutment platform. One end of each abutment spring abuts against the clamping frame, and the other end abuts against the inner wall of the clamping frame.

[0013] By adopting the above technical solution and setting the abutment spring, when the abutment platform drives the clamping frame to slide outward, thereby realizing the opening of the clamping frame, the abutment spring is continuously compressed, and when the anti-theft cover needs to be clamped, the driving member drives the abutment platform to slide back. During this process, the clamping frame moves back under the action of the elastic force of the abutment spring, and clamps the outer wall of the anti-theft cover under the action of the elastic force of the abutment spring.

[0014] Preferably, a roller is provided on one side of each clamping rack close to the abutment platform, each roller is rotatably connected to the corresponding clamping rack, and a side wall of each roller abuts against the abutment platform.

[0015] By adopting the above technical solution, the setting of the roller can effectively convert the sliding friction between the clamping frame and the abutment table into rolling friction, thereby effectively reducing the friction between the clamping frame and the abutment table, and further reducing the probability of wear between the clamping frame and the abutment table, effectively ensuring the service life of the clamping frame and the abutment table.

At the same time, the existence of the guide rod also effectively ensures the sliding stability of the lifting frame, thereby reducing the wear of the lifting frame during sliding.

[0018] Preferably, the number of the guide rods is set to be several.

[0019] By adopting the above technical solution, a plurality of guide rods are provided, which can further guide the sliding of the lifting frame, and at the same time further improve the stability of the lifting frame during sliding, thereby further reducing the wear of the lifting frame during sliding.

[0020] Preferably, an abutment groove is provided on the inner side wall of each clamping frame.

[0021] By adopting the above technical solution, the abutment groove is set so that when the anti-theft cover is tightened, the protrusion on the anti-theft cover can be embedded in the corresponding abutment groove, so that the clamping frame can abut against the protrusion on the anti-theft cover through the inner wall of the abutment groove, thereby realizing the rotation of the anti-theft cover, thereby reducing the probability of relative sliding between the clamping frame and the anti-theft cover when the clamping frame rotates.

[0022] Preferably, a rubber pad is provided on the inner side wall of each clamping frame.

[0023] By adopting the above technical solution and arranging the rubber pad, the clamping frame can contact the outer side wall of the anti-theft cover through the rubber pad, thereby effectively protecting the anti-theft cover and reducing the damage to the anti-theft cover caused by the clamping frame.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. The control mechanism is set such that after the anti-theft cover is clamped by the clamping frame, the buckle on the anti-theft cover is located in the placement groove. Then, after the anti-theft cover is tightened, the position detection component detects whether the buckle is located in the recessed cavity on the stacking barrel. When the position detection component detects that the buckle is completely located in the recessed cavity, the control component controls the rotating mechanism to close, so that the anti-theft cover maintains the current position, ensuring that the buckle is completely located in the recessed cavity, thereby reducing the probability of the buckle being located outside the recessed cavity after tightening, thereby reducing the probability of accidental wear of the buckle;

[0026] 2. The specific setting of the driving mechanism enables the driving member to drive the abutment platform to slide when the anti-theft buckle needs to be clamped, so that the guide surface on the abutment platform continuously abuts against the clamping frame and pushes the clamping frame to slide outward to open the clamping frame, so that the relevant personnel can control all the clamping frames by only one driving member, which is convenient for the operation of the relevant personnel;

[0027] 3. The setting of the abutment groove enables the protrusion on the anti-theft cover to be embedded in the corresponding abutment groove when the anti-theft cover is tightened, so that the clamping frame can abut against the protrusion on the anti-theft cover through the inner wall of the abutment groove to realize the rotation of the anti-theft cover, thereby reducing the probability of relative sliding between the clamping frame and the anti-theft cover when the clamping frame rotates.

[0035] Reference Figure 1 and Figure 2 The mounting frame 1 is fixedly mounted on the body of the capping machine by bolts. A plurality of guide rods 11 are also arranged on the mounting frame 1. In the embodiment of the present application, the number of guide rods 11 is set to two, and the two guide rods 11 are respectively located at both ends of the mounting frame 1 along its own length direction. Each guide rod 11 is vertically arranged, the middle part of each guide rod 11 is fixedly connected to the mounting frame 1, and the top end of each guide rod 11 is used for fixed connection with the capping machine. The bottom end of each guide rod 11 is extended downward, and each passes through the lifting frame 2, and each is slidably connected to the lifting frame 2.

[0036] Reference Figure 1 and Figure 2The mounting frame 1 is also provided with a lifting member 12. In the embodiment of the present application, the lifting member 12 is provided as a cylinder, the top of which is fixedly mounted to the bottom of the mounting frame 1 by bolts, the piston rod of which is vertically downwardly arranged and fixedly connected to the lifting frame 2 by bolts. The rotating mechanism 4 includes a rotating member 41, which is arranged at the bottom of the lifting frame 2.

[0037] Reference Figure 1 and Figure 2 In the embodiment of the present application, the rotating member 41 is configured as a servo motor, which is fixedly mounted on the bottom of the lifting frame 2 by bolts, and the output shaft of the servo motor is vertically arranged downward. The servo motor is also provided with a brake device, which is used to lock the output shaft of the servo motor when the output shaft of the servo motor stops. The brake device is a prior art, so it will not be described here.

[0038] Reference Figure 1 and Figure 3 The driving mechanism 5 includes a driving member 51 and an abutment platform 52. In the embodiment of the present application, the driving member 51 is configured as a cylinder, the top of which is fixedly connected to the output shaft of the rotating member 41 through a frame body, and the piston rod of the cylinder is vertically arranged downward and extends into the clamping frame 3 and is fixedly connected to the top of the abutment platform 52. The top of the clamping frame 3 is fixedly connected to the bottom of the cylinder body.

[0039] Reference Figure 3 In the embodiment of the present application, the abutment platform 52 is truncated, and a guide surface is provided on the side wall of the abutment platform 52. The cross-sectional area of ​​the abutment platform 52 gradually increases downward. The abutment platform 52 is slidably connected to the inner wall of the clamping frame 3, and the sliding direction of the abutment platform 52 is the vertical direction. In the embodiment of the present application, the number of the clamping frames 6 is set to three, and they are arranged at equal angles along the circumference of the axis direction of the clamping frame 3.

[0040] Reference Figure 3 Each clamping frame 6 includes a sliding frame 61 and a clamping claw 62. Each sliding frame 61 is located inside the clamping frame 6 and is slidably connected to the clamping frame 6. The straight line where the sliding direction of each sliding frame 61 is located is perpendicular to and intersects the axis of the abutment platform 52. The bottom end of each sliding frame 61 extends out of the bottom end of the clamping frame 6 and is fixedly connected to the corresponding clamping claw 62 by bolts.

[0041] Reference Figure 3, one end of each sliding frame 61 close to the abutment platform 52 is extended upward, and is provided with a roller 63, and each roller 63 is rotatably connected to the corresponding sliding frame 61 through a pin. Each roller 63 abuts against the guide surface on the abutment platform 52. Abutment spring 31 is sleeved on each sliding frame 61, and each abutment spring 31 is located on the side of the corresponding sliding frame 61 away from the abutment platform 52. One end of each abutment spring 31 abuts against the sliding frame 61, and the other end of each abutment spring 31 abuts against the inner side wall of the clamping frame 6.

[0042] Reference Figure 1 and Figure 3 In the initial state, that is, when the clamping frame 6 is in the closed state, the piston rod of the driving member 51 is located at the bottom of its displacement path. When the piston rod of the driving member 51 moves upward, the abutment platform 52 slides upward. At this time, the guide surface on the abutment platform 52 abuts against the roller 63, and pushes the roller 63 and the sliding frame 61 to slide away from the abutment platform 52, thereby driving the clamping jaw 62 and opening the clamping jaw 62. In this process, the abutment spring 31 is continuously compressed, thereby storing elastic potential energy.

[0043] Reference Figure 1 and Figure 3 When the anti-theft cover needs to be clamped, the piston rod of the driving member 51 moves downward, and the sliding frame 61 slides toward the abutment platform 52 under the elastic force of the abutment spring 31, and gradually approaches the anti-theft cover until the clamping claw 62 abuts against the anti-theft cover. At this time, the sliding frame 61 has not returned to the initial position, and the sliding frame 61 is separated from the abutment platform 52. At this time, the clamping claw 62 clamps the side wall of the anti-theft cover under the elastic force of the abutment spring 31.

[0044] Reference Figure 1 and Figure 4 A plurality of abutment grooves 621 are provided on the inner side wall of each clamping jaw 62, and the abutment grooves 621 are arranged one by one corresponding to the protrusions on the side wall of the anti-theft cover, so that the protrusions on the anti-theft cover are embedded in the corresponding abutment grooves 621. A rubber pad 64 is provided on the inner wall of each clamping jaw 62, and the rubber pad 64 is fixedly connected to the inner wall of the clamping jaw 62 by gluing. Each rubber pad 64 contacts the outer side wall of the anti-theft cover.

[0045] Reference Figure 1 and Figure 3In the embodiment of the present application, two position detection members 91 are provided, and both are infrared distance measuring sensors. The control member 92 is a PLC controller. The two position detection members 91, a driving member 51 and a rotating member 41 are all electrically connected to the control member 92. The position detection member 91 is fixedly mounted on the outer wall of the clamping frame 6 where the placement slot 8 is located, and is respectively located above the two ends of the placement slot 8. The control member 92 is fixedly mounted on the body of the capping machine. The position detection member 91 is used to detect the distance value between itself and the first object reached by the infrared ray, and feed the detected distance value back to the control member 92.

[0046] Reference Figure 1 and Figure 3 The control member 92 stores a preset distance value in advance. In the embodiment of the present application, the preset distance value is the distance value between the infrared emission point of the position detection member 91 and the inner bottom wall of the recessed cavity 71 on the stacking bucket 7. The control member 92 is used to receive the distance values ​​detected by the two position detection members 91 and compare the two distance values ​​with the preset distance value.

[0047] Reference Figure 1 and Figure 3 After the anti-theft cover is tightened, when the two detected distance values ​​are less than or equal to the preset distance value, the control member 92 determines that the buckle on the anti-theft ring is completely located in the recessed groove. At this time, the control member 92 controls the rotating member 41 to stop and controls the piston rod of the driving member 51 to move upward.

[0048] Reference Figure 1 and Figure 3 When a detected distance value is greater than the preset distance value, the control component 92 determines that the buckle portion on the anti-theft ring is located in the recessed groove. At this time, the control component 92 controls the rotating component 41 to rotate according to the specific detection situation, and makes the position detection component 91 that detects a distance value greater than the preset position value rotate in a direction close to another position detection component 91 until the detected distance values ​​are less than or equal to the preset distance value.

[0049] Reference Figure 1 and Figure 3 When the two detected distance values ​​are both greater than the preset distance values, the control member 92 determines that the buckle on the anti-theft ring is completely outside the recessed groove, and controls the rotating member 41 to rotate according to the specific detection situation until the detected distance values ​​are both less than or equal to the preset distance values.

[0050] The implementation principle of a capping clamping device according to an embodiment of the present application is as follows: when the anti-theft cap is tightened by the clamping frame 6, two position detection components 91 detect the distance value between themselves and the first object reached by the infrared rays, and feed back the detected distance value to the control component 92. When the detected distance value is greater than the preset distance value, the control component 92 controls the rotating component 41 to rotate forward or reverse according to the specific detection situation until both distance values ​​are less than or equal to the preset distance value. Thereafter, the control component 92 controls the clamping frame 6 to open through the driving component 51, and then controls the lifting component 12 to drive the lifting frame 2 to lift, thereby completing the capping.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
