Description

Technical Field

[0001] The utility model relates to the technical field of capping machines, in particular to a dial wheel used for capping machines. Background Art

[0002] The capping machine is also called a capping machine, a capping machine or a capping machine. Its main purpose is to automatically install and fasten the bottle cap to the bottle body during the production and processing of plastic bottles or glass bottles. It is widely used in food production, daily chemicals, medicine and other fields.

[0003] The working process of the capping machine is as follows: 1. The operator places the uncapped bottle on the conveyor belt. The conveyor belt starts to move and passes through a dial wheel with a slot and an assembly that can support the bottle. The dial wheel is used to separate the bottles on the conveyor belt at equal intervals and then transport them to the side of the robotic arm. At this time, the dial wheel will pull the bottle out of the assembly and the robotic arm will grab it. The robotic arm will automatically detect the height, width and other parameters of the bottle and automatically adjust according to the size of the bottle. After adjustment, the robotic arm will align the bottle with the capping device according to the preset program to prepare for the subsequent links; 2. When the bottle body is ready, the blank bottle cap has been transported to the bottom of the robotic arm of the capping machine through the conveyor belt. The robotic arm will position the bottle cap on the capping device according to the program and give it initial pressure to ensure the stability and accuracy of the subsequent links; 3. When the robotic arm has positioned the bottle cap, the capping machine will tighten the bottle cap on the bottle. The specific tightening process is that the bottle cap uses the rotating device to entangle the threads between the cap and the bottle mouth, and continuously rotate until the capping force is appropriate and stable to achieve the expected effect.

[0004] During the conveyor belt transportation process of the above-mentioned capping machine, since the glass bottles used in the capping machine are of different sizes, the shorter glass bottles cannot be smoothly pushed out from the push wheel, thereby affecting the overall production progress. Utility Model Content

[0005] The utility model solves the problem that a thumbwheel cannot smoothly push out bottles during the transportation process of a capping machine, and provides a thumbwheel for a capping machine, which can enable the thumbwheel to smoothly push out bottles from the thumbwheel and complete subsequent capping operations via a mechanical arm, thereby avoiding the situation in which products are retained on the thumbwheel and production progress is hindered.

[0006] The technical solution adopted by the utility model is:

[0007] A thumbwheel for a capping machine, comprising:

[0008] The thumbwheel body is rotatably connected to the support platform, and a clamping ring is circumferentially arranged on the outer wall of the thumbwheel body, and a plurality of clamping grooves for clamping the bottle are circumferentially arranged on the clamping ring; the first groove is located on the outer wall of the thumbwheel body, and the groove direction is toward the center of the thumbwheel body; the second groove is located on the outer wall of the clamping ring and extends to the inside of the thumbwheel body, and the groove direction is toward the center of the thumbwheel body, and the second groove is connected to the first groove; the pressure block is slidably connected to the inside of the first groove, and the end of the pressure block facing the center of the thumbwheel body is hinged with a first connecting rod, and a first spring is connected between the first connecting rod and the inner wall of the first groove; the second connecting rod is slidably connected to the inside of the second groove, and a third connecting rod is hinged between the second connecting rod and the first connecting rod for linking the first connecting rod and the second connecting rod; the fixed block is arranged on the support platform and is in intermittent sliding contact with the pressure block.

[0009] In some embodiments of the present invention, a bracket is hinged on the third connecting rod, and the bracket is arranged at the connection point between the first groove and the second groove. Both ends of the third connecting rod are respectively hinged between the first connecting rod and the second connecting rod.

[0010] In some embodiments of the present invention, a rotation radius of the third connecting rod is smaller than a distance between an inner bottom of the first groove and an inner top of the second groove.

[0011] In some embodiments of the utility model, two fourth connecting rods are also included, and the two fourth connecting rods are respectively provided with sliding grooves along their own axial directions. The third connecting rod is slidably connected in the sliding groove between the two second connecting rods, and the free ends of the two fourth connecting rods are respectively hinged to the first connecting rod and the second connecting rod, and the two ends of the third connecting rod are respectively provided with second springs connected to the inner side walls of the sliding groove.

[0012] In some embodiments of the present invention, a first clamping ring is circumferentially provided on the inner side wall of the slide slot to limit the third connecting rod from sliding out of the slide slot.

[0013] In some embodiments of the present invention, the second groove and the cross section of the thumbwheel body are formed at an acute angle, and the second groove is inclined toward the first groove.

[0015] In some embodiments of the present invention, a silicone protective pad is provided on the arc-shaped push block.

[0016] The beneficial effects of the utility model are:

[0017] When the thumbwheel body rotates on the support platform, the thumbwheel body pushes the bottle on the conveyor belt to the support platform through the clamping groove on the clamping ring. When the bottle is pushed by the thumbwheel body to the side close to the mechanical arm on the capping machine, the fixed block on the support platform contacts and squeezes the pressing block on the thumbwheel body that is rotating, so that the pressing block slides in the first groove toward the axial direction of the thumbwheel body, and in the connected first groove and second groove, the transmission between the third connecting rod and the second connecting rod makes the second connecting rod slide in the second groove along one end away from the thumbwheel body, thereby achieving a pushing force on the bottle clamped by the clamping ring on the support platform, making it convenient for the bottle to be pushed from the thumbwheel body to the mechanical arm and complete subsequent operations, thereby avoiding the product being retained on the support platform and affecting the subsequent bottle capping operation.

Of course, they are only examples and are not intended to limit the present invention.

[0028] The embodiments of the utility model are described in detail below with reference to the accompanying drawings.

[0029] Example

[0030] like Figure 1 As shown, this embodiment provides a dial wheel for a capping machine, comprising

[0031] A thumbwheel for a capping machine, comprising:

[0032] The dial body 2 is rotatably connected to the support platform 1, and a clamping ring 3 is circumferentially arranged on the outer wall thereof, and a plurality of clamping grooves 4 for clamping bottles are circumferentially arranged on the clamping ring 3;

[0033] The first groove 20 is located on the outer wall of the thumbwheel body 2, and the groove direction is toward the center of the thumbwheel body 2;

[0034] The second groove 21 is located on the outer wall of the collar 3 and extends to the inside of the thumbwheel body 2, and the groove direction faces the center of the thumbwheel body 2. The second groove 21 is connected to the first groove 20;

[0035] A pressure block 22 is slidably connected to the inside of the first groove 20. A first connecting rod 23 is hingedly connected to one end of the pressure block 22 facing the center of the thumbwheel body 2. A first spring 27 is connected between the first connecting rod 23 and the inner side wall of the first groove 20.

[0036] The second connecting rod 24 is slidably connected to the inside of the second groove 21, and a third connecting rod 25 is hinged between the second connecting rod 23 and the first connecting rod 23, so as to link the first connecting rod 23 and the second connecting rod 24;

[0037] The fixed block 5 is disposed on the supporting platform 1 and is in intermittent sliding contact with the pressing block 22 .

[0038] The thumbwheel body 2 can rotate on the support platform 1. Under the action of the clamp ring 3 on the thumbwheel body 2, the support platform 1 pushes the bottles on the conveyor belt to the support platform 1 to separate them, so that the subsequent robot arm can grab and complete the capping operation. The fixed block 5 on the support platform 1 is set close to one side of the robot arm on the capping machine. The second groove 21 is located above the first groove 20. The third link 25 is located at the connection between the first groove 20 and the second groove 21, and in the present embodiment, it is hinged on the side wall of the connection near the middle part; in addition, the third link 25 may not be hinged to the side wall of the connection between the first groove 20 and the second groove 21. To realize that the first link 23 pushes the second link 24 to move through the third link 25, the third link 25 is required to be pushed by the first link 23 until the third link 25 contacts the side walls of the first groove 20 and the second groove 21. Since the third link 25 itself is long enough and the first link 23 applies force to the third link 25 at this time, the third link 25 rotates with the contact point between itself and the first groove 20 and the second groove 21 as the center, thereby pushing the second link 24. Both can realize the linkage effect between the first link 23 and the second link 24 through the third link 25. There is no gap between the pressing block 22 and the inner wall of the first groove 20 , and when the first spring 27 is in a free state, part of the pressing block 22 is still inside the first groove 20 and will not be separated from the thumbwheel body 2 .

[0039] When in use, the clamping ring 3 on the thumbwheel body 2 separates the bottles on the conveyor belt through the clamping groove 4 and moves them to the support platform 1, and adjusts the position on the support platform 1 together with the rotation of the thumbwheel body 2. After the thumbwheel body 2 moves the bottle to the side close to the mechanical arm on the capping machine, the fixed block 5 on the support platform 1 contacts the pressing block 22 slidably connected to the thumbwheel body 2. Since the fixed block 5 is fixed in position, the pressing block 22 is squeezed by the fixed block 5 and slides in the first groove 20 toward the axis direction of the thumbwheel body 2. During the sliding process of the pressing block 22, the first connecting rod 23 hinged on the pressing block 22 will also move in the same direction as the pressing block 22. During the movement, the end of the first connecting rod 23 away from the pressing block 22 is hinged to the third connecting rod 25, which makes the third connecting rod 25 rotate with its own hinge point as the center of the circle under the push of the first connecting rod 23, so that the second connecting rod 24 hinged at the other end of the third connecting rod 25 moves. The second connecting rod 24 moves in the second groove 21 along the radial direction of the thumbwheel body 2, so that the thumbwheel body 2 can assist the thumbwheel body 2 in moving the bottle held on the clamp ring 3 to the position of the mechanical arm on the capping machine under the push of the second connecting rod 24, so as to avoid the situation that the thumbwheel body 2 cannot smoothly push the bottle out and cause the product to be retained. When the bottle in a clamping groove 4 on the clamp ring 3 is pulled out, since the clamping grooves 4 are arranged on the clamp ring 3 at multiple circumferential intervals, the fixed block 5 and the pressing block 22 are separated from each other, and the pressing block 22, under the action of the first spring 27 in the first groove 20, exerts force on the first connecting rod 23 through the elastic deformation of the first spring 27 itself, so that the pressing block 22 returns to the initial position, so as to assist the thumbwheel body 2 in pushing out the next bottle.

[0040] It is worth noting that in the above embodiment, when the fixing block 5 is not in contact with the pressing block 22 to cause squeezing, the second connecting rod 24 is completely located in the second groove 21, so as to prevent the clamping groove 4 on the clamping ring 3 from being blocked by the second connecting rod 24 when clamping the bottle, thereby causing the bottle to be stuck during transportation; in addition, since the second connecting rod 24 and the third connecting rod 25 are hinged, when the third connecting rod 25 rotates, it will cause the second connecting rod 24 to deviate. Therefore, the second groove 21 should be set to have a trapezoidal cross-section so that the second groove 21 will not affect the deviation of the second connecting rod 24.

[0041] Further, such as Figure 2 As shown, a bracket 26 is hinged on the third connecting rod 25 , and the bracket 26 is arranged at the connection point between the first groove 20 and the second groove 21 . Both ends of the third connecting rod 25 are hinged between the first connecting rod 23 and the second connecting rod 24 , respectively.

[0042] The bracket 26 is located at the connection point between the first groove 20 and the second groove 21 . The H-shaped bracket 26 selected in this embodiment can hinge the third connecting rod 25 and fix itself at the connection point between the first groove 20 and the second groove 21 .

[0043] When in use, the bracket 26 is fixedly arranged on the side wall of the connection between the first groove 20 and the second groove 21, and provides support for the third connecting rod 25 hinged on the bracket 26. When the first connecting rod 23 pushes the third connecting rod 25, the third connecting rod 25 rotates with the hinge point between itself and the bracket 26 as the center of the circle, so as to push the second connecting rod 24 on the other side to move. Compared with the third connecting rod 25 rotating after contacting the side wall of the connection between the first groove 20 and the second groove 21, the arrangement of the bracket 26 can achieve the effect of instant linkage between the first connecting rod 23 and the second connecting rod 24, thereby avoiding a long time of operation delay when the bottle is dialed out by the dial wheel body 2.

[0044] Further, such as Figure 1-3 As shown, the rotation radius of the third connecting rod 25 is smaller than the distance between the inner bottom of the first groove 20 and the inner top of the second groove 21 .

[0045] Since the first groove 20 and the second groove 21 are opened toward the axial direction of the thumbwheel body 2 , from the axial cross section of the thumbwheel body 2 , the shortest distance between the inner bottom of the first groove 20 and the inner top of the second groove 21 should be greater than the rotation radius of the third connecting rod 25 .

[0046] When in use, the third connecting rod 25 can rotate unhindered in the first groove 20 and the second groove 21 under the push of the first connecting rod 23, so that the linkage between the first connecting rod 23 and the second connecting rod 24 is smoother.

[0047] Further, such as Figure 4 and Figure 5 As shown, it also includes two fourth connecting rods 6, and the two fourth connecting rods 6 are respectively provided with sliding grooves 60 along their own axial directions. The third connecting rod 25 is slidably connected in the sliding groove 60 between the two second connecting rods 24. The free ends of the two fourth connecting rods 6 are respectively hinged to the first connecting rod 23 and the second connecting rod 24, and the two ends of the third connecting rod 25 are respectively provided with second springs 61 connected to the inner side walls of the sliding groove 60.

[0048] The two fourth links 6 are respectively located at the two ends of the third link 25, one is used to simultaneously hinge the first link 23 and the third link 25, and the other is used to simultaneously hinge the second link 24 and the third link 25. The second springs 61 are respectively located in the sliding grooves 60 opened on the two fourth links 6, so that relative sliding occurs between the third link 25 and the fourth link 6.

[0049] When in use, after the pressing block 22 on the first connecting rod 23 is in contact and squeezed with the fixing block 5, the first connecting rod 23 drives the third connecting rod 25 to rotate through the hinged fourth connecting rod 6, and the third connecting rod 25 rotates around the hinge point on the inner side wall where the third connecting rod 25 is connected with the first groove 20 and the second groove 21, so that the fourth connecting rod 6 hinged to the second connecting rod 24 will also push the second connecting rod 24 to move in the second groove 21 to push the bottle. This process does not require the cross-section of the second groove 21 to be set in a trapezoidal shape.

[0050] Further, such as Figure 5 As shown, a first clamping ring 62 is circumferentially provided on the inner side wall of the slide groove 60 to limit the third connecting rod 25 from sliding out of the slide groove 60 .

[0051] The first retaining ring 62 is arranged on the inner wall of the slide groove 60 opened on the fourth connecting rod 6 and close to the opening position of the slide groove 60. The part of the third connecting rod 25 located in the slide groove 60 is correspondingly provided with a second retaining ring 7 adapted to the first retaining ring 62, which is used to limit the third connecting rod 25 from sliding out of the slide groove 60.

[0052] When in use, the third link 25 is hinged to the first link 23 and the second link 24 respectively through the fourth link 6. When the first link 23 pushes the fourth link 6 to drive the third link 25 to rotate, the third link 25 rotates with its own hinge point as the center of the circle, and the fourth link 6 will be under the action of the second spring 61 in the slide groove 60, so that the second snap ring 7 on the third link 25 and the first snap ring 62 on the inner wall of the slide groove 60 contact. At this time, the first snap ring 62 on the inner wall of the slide groove 60 can prevent the third link 25 from continuing to slide in the slide groove 60 until it falls off between the fourth link 6.

[0053] Further, such as Figure 6 As shown, the second groove 21 is formed at an acute angle with the cross section of the thumbwheel body 2 , and the second groove 21 is inclined toward the first groove 20 .

[0054] The second groove 21 is inclined at a certain angle on the outer wall of the clamping ring 3, that is, the groove direction of the second groove 21 and the cross section of the dial body 2 form an acute angle. A straight line a is drawn in the groove direction of the second groove 21, the cross section of the dial body 2 is b, and the intersection of the straight line a on the cross section b is c, that is, the acute angle is located at the angle on the side of the intersection c toward the outside of the dial body 2.

[0055] When in use, the inclined second groove 21 can enable the second connecting rod 24 located in the second groove 21 to push the bottle at a certain angle. When the size of the bottle changes, the position where the second connecting rod 24 pushes the bottle will also change. If the bottle body is small, the position where the second connecting rod 24 pushes the bottle will be close to the upper part of the bottle body. At this time, the second connecting rod 24 pushing the bottle may cause the bottle to tilt and fall. Therefore, the second groove 21 is set to be inclined to change the pushing angle of the second connecting rod 24 to avoid the bottle falling.

[0056] Furthermore, an arc-shaped push block is provided at one end of the second connecting rod 24 away from the axis of the thumbwheel body 2 .

[0057] After the arc-shaped push block is provided on the second connecting rod 24, the arc-shaped push block and the second groove 21 are slidably connected, while the second connecting rod 24 is not slidably connected to the second groove 21. When the third connecting rod 25 rotates, the second connecting rod 24 will be displaced. If the second connecting rod 24 and the second groove 21 are slidably connected, the second connecting rod 24 will be squeezed and damaged.

[0058] When in use, the arc-shaped push block is adapted to the contour shape of the bottle itself, so that when the bottle is pushed, there will not be excessive positional deviation in the circumferential direction of the thumbwheel body 2 .

[0059] Furthermore, a silicone protective pad is provided on the arc-shaped push block.

[0060] When in use, the silicone protective pad on the arc-shaped push block can protect the bottle when it contacts the bottle held by the card slot 4, thereby preventing the bottle from being damaged.

[0061] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. In the absence of conflicts, the embodiments of the present application and the features in the embodiments may be arbitrarily combined with each other. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
