Description

Technical Field

[0001] This utility model relates to the field of capping machines, and more particularly to a capping device for a capping machine. Background Technology

[0002] A capping machine is a device used to tighten bottle caps after products have been packaged. By tightening the caps, the packaging is sealed, preventing the intrusion of external moisture, air, microorganisms, etc., thus extending the shelf life of food, medicine and other products and ensuring stable quality. At the same time, a tight cap can prevent liquid leakage and solid spillage, improve the safety of products during storage and transportation, and reduce losses.

[0003] Some existing capping machines lack the function of securing the bottle, causing the bottle to tilt during capping and making it impossible to tighten the cap. In addition, when it is necessary to change to other sizes of caps, the size of the capping opening cannot be adjusted, resulting in poor compatibility. This necessitates the replacement of capping machines with different sizes, which increases equipment costs and reduces production flexibility.

[0004] Therefore, those skilled in the art have provided a capping device for a capping machine to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a capping device for a capping machine. A second electric push rod pushes a push block, causing a second slider to move from the inside out. When the second electric push rod pulls the push block, it causes the second slider to move from the outside in, thus securing the bottle cap. The diameter of the capping opening can then be adjusted using a threaded rod. This capping mechanism can accommodate a wider range of bottle caps, reducing equipment replacement and increasing production flexibility.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A capping device for a capping machine includes a support plate. A first electric push rod is fixedly connected to the center of the inner top surface of the support plate. A fixing mechanism is provided at the output end of the first electric push rod. The fixing mechanism includes a gear box fixedly connected to the output end of the first electric push rod. A first motor is fixedly connected to the center of the lower surface of the gear box. A gear is fixedly connected to the output end of the first motor. A connecting block is fixedly connected to the lower surface of the first motor. A toothed rod is slidably connected to both the front and rear ends inside the gear box. A moving rod is fixedly connected to the outer wall of the toothed rod on the side away from the gear box. Two arc-shaped rods are fixedly connected to the body of each moving rod.

[0008] The lower end of the connecting block is provided with a capping mechanism. The capping mechanism includes a second motor fixedly connected to the lower surface of the connecting block. The output end of the second motor is fixedly connected to a protective box. The lower end of the protective box is provided with multiple limit boxes. The middle part of the upper surface of the limit box is fixedly connected with a second electric push rod. The output end of the second electric push rod passes through the limit box and is fixedly connected to a push block. The lower end of the push block is provided with multiple second sliders. The lower surface of the second slider is provided with an adjustment groove. The inside of the adjustment groove is provided with a clamping plate.

[0009] The above technical solution uses a second electric push rod to push the push block, causing the second slider to move from the inside out. When the second electric push rod pulls the push block, it causes the second slider to move from the outside in, thus fixing the bottle cap. The diameter of the capping opening can then be adjusted by a threaded rod. The capping mechanism can accommodate more bottle caps, reduce equipment replacement, and increase production flexibility.

[0010] Furthermore, a second groove is provided on the outer wall of the rear end of the second slider, and the pushing block slides inside the second groove;

[0011] The above technical solution allows the second slider to move upward by pushing the block to slide inside the second groove.

[0012] Furthermore, the inside of the adjustment groove is fixedly connected to two sides near the center, and the clamping plate slides on the body of the fixed rod;

[0013] The above technical solution allows the clamp to slide on the body of the fixed rod, thereby limiting the movement of the clamp.

[0014] Furthermore, a threaded rod is rotatably connected to the center of the adjustment groove, the clamping plate is threadedly connected to the threaded rod, and a fixing block is fixedly connected to the outer wall of the front end of the threaded rod;

[0015] The above technical solution allows the threaded rod to be rotated via a fixed block, thereby enabling the clamping plate to move.

[0016] Furthermore, a working platform is fixedly connected to the lower surface of the support plate, and multiple mounting slots are provided on one side of the upper surface of the working platform;

[0017] The above technical solution allows for the connection of other transmission devices via the installed mounting slots, enabling the transfer of bottles.

[0018] Furthermore, the gear meshes with the rack;

[0019] The above technical solution allows the moving rod to move.

[0020] Furthermore, the lower end of the inner wall of the limiting box is provided with a plurality of first sliding grooves, and the lower ends of the outer walls on both sides of the second slider are fixedly connected with third sliders, the third sliders sliding inside the first sliding grooves;

[0021] With the above technical solution, the second slider can be moved inward and outward by sliding the third slider inside the first groove.

[0022] Furthermore, the protective box is fixedly connected to the limiting box;

[0023] Through the above technical solution, the protective box and the limiting box are fixedly connected, so that the limiting box can rotate with the protective box.

[0024] This utility model has the following beneficial effects:

[0025] 1. The capping device of the capping machine proposed in this utility model, compared with some existing capping devices, uses a first motor to drive a gear, then the gear to drive a rack, then the rack to drive a moving rod, thereby driving an arc-shaped rod. Through the set fixing mechanism, the bottle can be fixed, effectively preventing the bottle from shaking during capping, thus affecting the quality of capping.

[0026] 2. The capping device of the capping machine proposed in this utility model, compared with some existing capping devices, uses a second electric push rod to push the push block, causing the second slider to move from the inside to the outside. When the second electric push rod pulls the push block, it causes the second slider to move from the outside to the inside, thereby fixing the bottle cap. Then, the diameter of the capping opening can be adjusted by the threaded rod. Through the set capping mechanism, more bottle caps can be accommodated, reducing the need to change equipment and increasing production flexibility. Attached Figure Description

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.

[0041] Reference Figure 1 , Figure 3 and Figure 6 One embodiment provided by this utility model:

[0042] A capping device for a capping machine includes a support plate 1. A first electric push rod 4 is fixedly connected to the center of the inner top surface of the support plate 1. A fixing mechanism 5 is provided at the output end of the first electric push rod 4. The fixing mechanism 5 includes a gear box 506 fixedly connected to the output end of the first electric push rod 4. A first motor 505 is fixedly connected to the center of the lower surface of the gear box 506. A gear 501 is fixedly connected to the output end of the first motor 505. A connecting block 507 is fixedly connected to the lower surface of the first motor 505. A toothed rod 502 is slidably connected to both the front end and the rear end inside the gear box 506. A moving rod 503 is fixedly connected to the outer wall of the toothed rod 502 on the side away from the gear box 506. Two arc-shaped rods 504 are fixedly connected to the body of the moving rod 503.

[0043] A capping mechanism 2 is provided at the lower end of the connecting block 507. The capping mechanism 2 includes a second motor 214 fixedly connected to the lower surface of the connecting block 507. A protective box 201 is fixedly connected to the output end of the second motor 214. A plurality of limit boxes 212 are provided at the lower end of the protective box 201. A second electric push rod 202 is fixedly connected to the middle of the upper surface of the limit box 212. The output end of the second electric push rod 202 passes through the limit box 212 and is fixedly connected to a push block 204. A plurality of second sliders 211 are provided at the lower end of the push block 204. An adjustment groove 213 is opened on the lower surface of the second slider 211. A clamping plate 207 is provided inside the adjustment groove 213.

[0044] The second electric push rod 202 pushes the push block 204, causing the second slider 211 to move from the inside to the outside. When the second electric push rod 202 pulls the push block 204, it causes the second slider 211 to move from the outside to the inside, thus fixing the bottle cap. Then, the diameter of the capping opening is adjusted by the threaded rod 206. The capping mechanism 2 can accommodate more bottle caps, reduce equipment replacement, and increase production flexibility.

[0045] Reference Figure 4 , Figure 5 and Figure 7 The outer wall of the rear end of the second slider 211 is provided with a second slide groove 205. The push block 204 slides inside the second slide groove 205. By sliding the push block 204 inside the second slide groove 205, the second slider 211 can be moved upward. The two sides of the adjustment groove 213 near the middle are fixedly connected to the fixing rods 208. The clamping plate 207 slides on the rod body of the fixing rod 208. By sliding the clamping plate 207 on the rod body of the fixing rod 208, the clamping plate 207 can be limited to move.

[0046] Reference Figure 1 , Figure 2 and Figure 7A threaded rod 206 is rotatably connected to the center of the adjusting groove 213. The clamping plate 207 is threadedly connected to the threaded rod 206. A fixing block 209 is fixedly connected to the outer wall of the front end of the threaded rod 206. The threaded rod 206 can be rotated through the fixing block 209, thereby allowing the clamping plate 207 to move. A working platform 3 is fixedly connected to the lower surface of the support plate 1. Multiple mounting slots 6 are provided on one side of the upper surface of the working platform 3. Other transmission equipment can be connected through the mounting slots 6 for the transmission of bottles.

[0047] Reference Figure 3 , Figure 4 and Figure 5 The gear 501 meshes with the rack 502, which can move the moving rod 503. The lower end of the inner wall of the limiting box 212 is provided with multiple first sliding grooves 203. The lower ends of the outer walls on both sides of the second slider 211 are fixedly connected with third sliders 210. The third sliders 210 slide inside the first sliding grooves 203. By sliding the third sliders 210 inside the first sliding grooves 203, the second slider 211 can be moved inward and outward.

[0048] Reference Figure 2 , Figure 3 and Figure 4 The protective box 201 is fixedly connected to the limiting box 212. Through the fixed connection between the protective box 201 and the limiting box 212, the limiting box 212 can rotate with the protective box 201.

[0049] Working principle: When using this device, the first electric push rod 4 is activated to move the gear box 506 downward. At the same time, the first motor 505 drives the gear 501 to rotate, thereby driving the meshing rack 502 to move inward, thus moving the arc rod 504 inward, thereby fixing the bottle. Simultaneously, the second electric push rod 202 pushes the push block 204 downward, and then the third slider 210 moves outward through the first slide groove 203. The second electric push rod 202 then drags the push block 204 upward, and then the second slider 211 moves inward, thereby fixing the bottle cap with the clamping plate 207. Then, the second motor 214 drives the protective box 201 to rotate the entire capping mechanism 2, thereby tightening the bottle cap. When it is necessary to adjust the size of the capping opening, the fixed block 209 is rotated to rotate the threaded rod 206. Then, the fixed rod 208 limits the clamping plate 207, so that the clamping plate 207 can only move horizontally, thereby adjusting the size of the capping opening.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
