Description

Technical Field

[0001] This application relates to the field of capping equipment technology, and in particular to a capping anti-slip mechanism for a double-head capping machine. Background Technology

[0002] A capping machine, also called a sealing machine, pressing machine, or locking machine, is mainly used for plastic bottles and glass bottles.

[0003] However, most existing capping structures rely on motors to rotate the cap. Due to the inertia generated by the mechanical rotation, which is difficult to control, the motor stops after the cap is tightened. However, due to inertia, the tightening structure will continue to rotate, causing the already tightened cap to continue to rotate. This can lead to the cap being over-tightened or stripped, which can easily result in substandard processing and affect the quality of the finished product. Utility Model Content

[0004] This application provides a capping anti-slip mechanism for a double-head capping machine to solve the problem of over-tightening.

[0005] This application provides a capping anti-slip mechanism for a double-head capping machine, including a structural side plate. Multiple sets of transport rollers are movably connected to one side of the structural side plate, and these rollers are linearly distributed along one side of the structural side plate. A workpiece body is placed on top of the multiple sets of transport rollers. A bottle cap feeding box is provided on one side of the structural side plate, and an electric height adjustment seat is installed on the top of the bottle cap feeding box. A capping belt is provided at the bottom of the connecting plate of the electric height adjustment seat, and two sets of capping rotating shafts are arranged inside the capping belt. The two sets of capping rotating shafts are arranged in a linear pattern within the capping belt. The two sets of capping shafts are symmetrically distributed, with capping side plates on their outer sides. A capping motor is installed on one side of each capping side plate. A drive sleeve is fixedly connected to one side of the output shaft of the capping motor. Multiple sets of elastic paddles are installed on the inner wall of the drive sleeve, and these elastic paddles are arranged in a ring on the inner wall of the drive sleeve. Multiple sets of shaft slots are opened on the outer wall of one set of capping shafts, and these shaft slots are arranged in a ring on the outer wall of the one set of capping shafts. Multiple sets of resistance strips are installed on the outer side of the capping belt, and these resistance strips are arranged linearly on the outer side of the capping belt.

[0006] Furthermore, a transport motor is installed on one side of the transport roller, and two sets of transport bearings are installed at both ends of the transport roller. The two sets of transport bearings are symmetrically distributed at both ends of the transport roller. Two sets of drive wheels are fixedly connected to both ends of the transport roller. The two sets of drive wheels are symmetrically distributed at both ends of the transport roller, and a drive belt is installed on the outer side of the drive wheels.

[0007] Furthermore, an L-shaped structural plate is fixedly connected to the top of the structural side plate, a lifting plate is movably connected to the bottom of the L-shaped structural plate, a rubber clamp is installed at the bottom of the lifting plate, a lifting cylinder is installed at the top of the L-shaped structural plate, and a lifting output rod is provided at the bottom of the lifting cylinder.

[0008] Furthermore, two sets of guide rods are fixedly connected to the top of the lifting plate, and the two sets of guide rods are symmetrically distributed on the top of the lifting plate.

[0009] Furthermore, the top of the bottle cap feeding box is provided with multiple sets of feeding pipes, which are linearly distributed on the top of the bottle cap feeding box. The inside of the bottle cap feeding box is provided with multiple sets of guide grooves, which are linearly distributed inside the bottle cap feeding box.

[0011] Furthermore, a capping side plate is provided on one side of the transport roller.

[0012] Beneficial effects:

[0013] To address the issue of over-tightening, a capping motor drives a drive sleeve to rotate. Multiple sets of elastic tabs on the inner wall of the drive sleeve engage with multiple sets of shaft slots, thereby rotating a capping shaft to ensure effective capping. The capping is achieved through friction between the capping belt and the bottle cap. Since the elastic tabs are made of elastic material, once the bottle cap is tightened, the friction between the capping belt and the bottle cap increases, causing the elastic tabs to bend and unable to engage with the multiple shaft slots, thus preventing the capping shaft from rotating. This prevents the capping belt from moving, further avoiding over-rotation of the bottle cap and achieving the device's anti-slip capping function.

[0027] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0028] This utility model provides, for example Figure 1-4The illustrated capping anti-slip mechanism of a double-head capping machine includes a structural side plate 1. Multiple sets of transport rollers 2 are movably connected to one side of the structural side plate 1, and these rollers are linearly distributed along one side. A workpiece body 3 is placed on top of each set of transport rollers 2. A bottle cap feeding box 14 is located on one side of the structural side plate 1. An electric height adjustment seat 20 is installed on the top of the bottle cap feeding box 14. A capping belt 21 is located at the bottom of the connecting plate of the electric height adjustment seat 20. Two sets of capping rotating shafts 22 are symmetrically distributed inside the capping belt 21. Two sets of capping shafts 22 are provided with capping side plates 23 on their outer sides. A capping motor 24 is installed on one side of the capping side plate 23. A drive sleeve 25 is fixedly connected to one side of the output shaft of the capping motor 24. Multiple sets of elastic paddles 26 are installed on the inner wall of the drive sleeve 25. The multiple sets of elastic paddles 26 are arranged in a ring on the inner wall of the drive sleeve 25. Multiple sets of shaft slots 27 are opened on the outer wall of one set of capping shafts 22. The multiple sets of shaft slots 27 are arranged in a ring on the outer wall of one set of capping shafts 22. Multiple sets of resistance strips 28 are installed on the outer side of the capping belt 21. The multiple sets of resistance strips 28 are arranged linearly on the outer side of the capping belt 21.

[0029] The structure includes a side plate 1 that supports multiple sets of transport rollers 2, which transport the bottles to be tightened (i.e., the workpiece body 3). The bottle cap loading box 14 is a bottle cap transport and storage component; its top electric height adjustment seat 20 uses electricity to drive the tightening assembly to rise and fall, ensuring close contact between the tightening assembly and the workpiece and bottle cap. The cap tightening belt 21 is the main cap tightening component, driven by a cap tightening motor 24 to rotate two sets of cap tightening shafts 22, thereby moving the cap tightening belt 21. A drive sleeve 25 is fitted onto the cap tightening shafts 22. Furthermore, multiple sets of elastic paddles 26 on its inner wall engage with multiple sets of shaft slots 27, thereby driving a set of capping shafts 22 to rotate through the rotation of the drive sleeve 25, and ensuring the drive of the capping belt 21. Since the multiple sets of elastic paddles 26 are made of elastic material, the friction between the capping belt 21 and the cap will increase after the cap has been tightened, causing the elastic paddles 26 to bend and unable to engage with the multiple sets of shaft slots 27, and unable to drive the capping shafts 22 to rotate. This prevents the capping belt 21 from moving, further avoiding excessive rotation of the cap and realizing the capping anti-slip function of the device.

[0030] A transport motor 4 is installed on one side of the transport roller 2, and two sets of transport bearings 5 ​​are installed at both ends of the transport roller 2. The two sets of transport bearings 5 ​​are symmetrically distributed at both ends of the transport roller 2. Two sets of drive wheels 6 are fixedly connected to both ends of the transport roller 2. The two sets of drive wheels 6 are symmetrically distributed at both ends of the transport roller 2, and a drive belt 7 is installed on the outside of the drive wheels 6.

[0031] When the transport motor 4 is powered on, it can drive a set of drive wheels 6 to rotate. The drive wheels 6 drive multiple sets of drive wheels 6 to rotate through the drive belt 7, thereby driving multiple sets of transport rollers 2 to rotate synchronously. The workpiece body 3 is moved by the friction between the multiple sets of transport rollers 2 and the workpiece body 3. Two sets of transport bearings 5 ​​provide support for the transport rollers 2 to ensure the rotational stability of the transport rollers 2.

[0032] An L-shaped structural plate 8 is fixedly connected to the top of the structural side plate 1. A lifting plate 9 is movably connected to the bottom of the L-shaped structural plate 8. A rubber clamping plate 10 is installed at the bottom of the lifting plate 9. A lifting cylinder 11 is installed at the top of the L-shaped structural plate 8. A lifting output rod 12 is provided at the bottom of the lifting cylinder 11.

[0033] The L-shaped structural plate 8 provides support for the upper positioning component; the lifting cylinder 11, when powered on, can drive the lifting plate 9 to rise and fall through the lifting output rod 12, and can press the workpiece body 3 through the bottom slot of the rubber clamp 10 to achieve the positioning of the workpiece.

[0034] Two sets of guide rods 13 are fixedly connected to the top of the lifting plate 9, and the two sets of guide rods 13 are symmetrically distributed on the top of the lifting plate 9.

[0035] Among them, two sets of guide rods 13 can slide along the top groove of the L-shaped structural plate 8, thereby guiding the lifting plate 9 and ensuring its stability during lifting.

[0036] The top of the bottle cap feeding box 14 is provided with multiple sets of feeding pipes 15, which are linearly distributed on the top of the bottle cap feeding box 14. The inside of the bottle cap feeding box 14 is provided with multiple sets of guide grooves 16, which are linearly distributed inside the bottle cap feeding box 14.

[0037] The multiple sets of feed pipes 15 make it convenient for users to put bottle caps into the bottle cap feeding box 14, and guide the bottle caps through multiple sets of guide grooves 16 to ensure that the opening of the bottle cap can contact the bottle mouth of the workpiece body 3.

[0038] Multiple sets of feeding cylinders 17 are installed on one side of the U-shaped plate of the bottle cap feeding box 14. The multiple sets of feeding cylinders 17 are linearly distributed on one side of the U-shaped plate of the bottle cap feeding box 14. A feeding output rod 18 is provided on one side of the feeding cylinder 17.

[0039] Among them, multiple sets of feeding cylinders 17 correspond to multiple sets of guide grooves 16. When the multiple sets of feeding cylinders 17 are energized, the bottle cap in the guide groove 16 can be pushed to contact the bottle mouth of the workpiece body 3 through the feeding output rod 18 to complete the docking. This feeding method can continuously provide support for the bottle cap without affecting the rotation of the bottle cap.

[0040] A capping side plate 19 is provided on one side of the transport roller 2.

[0041] The screw cap side plate 19 is configured to provide support for multiple sets of transport rollers 2, while also providing support for the workpiece body 3, and can open the bottle mouth of the workpiece body 3 to avoid subsequent docking with the bottle cap.

[0042] Working principle: When using the anti-slip mechanism of this double-head capping machine, the user places the bottle to be capped, i.e. the workpiece body 3, on the transport roller 2. Then the user powers on the transport motor 4. When the transport motor 4 is powered on and started, it will drive the drive wheel 6 to rotate through the output shaft. The drive wheel 6 drives multiple sets of drive wheels 6 to rotate through the drive belt 7, thereby driving multiple sets of transport rollers 2 to rotate synchronously. Thus, the workpiece body 3 is transported by the friction between the rollers and the workpiece body 3.

[0043] When the workpiece body 3 is transported to the bottom of the lifting plate 9, the user powers on the lifting cylinder 11 and de-powers the transport motor 4. When the lifting cylinder 11 is powered on and started, it will drive the rubber plate 10 below the lifting plate 9 to descend through the lifting output rod 12, thereby pressing and positioning several workpiece bodies 3 through the bottom slot of the rubber plate 10.

[0044] Then, the user places the bottle cap with the opening facing the conveyor roller 2 into the guide groove 16 of the bottle cap feeding box 14 through the feeding pipe 15. Then, the user powers on the feeding cylinder 17. When the feeding cylinder 17 is powered on and started, it will push the bottle cap along the guide groove 16 through the feeding output rod 18 to dock with the bottle mouth of the workpiece body 3. Then, the user drives the capping belt 21 to descend and contact the bottle cap through the power of the electric height adjustment seat 20, thereby completing the docking of the bottle cap and the bottle.

[0045] Then, the user powers on the capping motor 24. When the capping motor 24 is powered on and started, it will drive the drive sleeve 25 to rotate. Multiple sets of elastic tabs 26 on the inner wall of the drive sleeve 25 engage with the shaft slots 27 on a set of capping shafts 22, thereby driving the capping shafts 22 to rotate. The capping shafts 22 then drive the capping belt 21 to move. The friction between the multiple sets of resistance strips 28 on the capping belt 21 and the anti-slip grooves on the cap drives the cap to rotate and tighten onto the bottle mouth, thus achieving capping. After the cap is tightened, the friction between the cap and the capping belt 21 will increase, causing the elastic tabs 26 to bend due to greater resistance, thus preventing the capping shafts 22 and the capping belt 21 from rotating and moving, thereby preventing slippage. Finally, the user can activate the lifting cylinder 11 again to lift the lifting plate 9 and no longer press and position the workpiece body 3, thus realizing the capping anti-slip function of the capping anti-slip mechanism of a double-head capping machine.

[0046] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
