Description

Technical Field

[0001] The invention relates to a capping machine, in particular to a detachable capping mechanism. Background Art

[0002] In daily life, people often use products packaged in bottles, especially in the food, medicine and cosmetics industries, and most of these bottles are capped by capping machines. At present, most capping machines use sleeves to wrap the entire silicone sleeve for the capping heads that are in direct contact with the bottle caps. Since the silicone sleeve can be elastically deformed, the sleeve can easily contact the bottle cap and bottle during the capping operation, causing scratches on the outer surface of the bottle cap and bottle. At the same time, since the silicone sleeve is elastically deformed when it is squeezed, when the capping is completed, the silicone sleeve will return to its original shape and absorb the bottle cap and bottle, making it difficult for the bottle to fall off the capping head. Summary of the invention

[0003] The present invention aims to provide a detachable screw-capping mechanism which will not cause damage to the bottle body and can easily cause the bottle to fall off.

[0004] To achieve the above purpose, the following scheme is provided: a detachable screw-on cover mechanism, comprising a pressing cover, and also comprising a locking piece, a sleeve and a silicone sleeve, wherein the sleeve is arranged outside the silicone sleeve and the two are fixed by the locking piece; the silicone sleeve comprises a silicone sleeve body, a silicone pad, a spline, a card slot, a screw-on cover hole and a vent hole, a spline is arranged on the outer wall of the silicone sleeve body, a card slot is arranged on the key body of the spline, a conical screw-on cover hole is arranged at one end of the silicone sleeve body, a spirally distributed anti-skid pattern is arranged on the hole wall of the screw-on cover hole, and the anti-skid pattern is a curved solid structure formed by sweeping a sine curve, a silicone pad is arranged at the end of the silicone sleeve body at which the screw-on cover hole is opened, and a vent hole connected to the screw-on cover hole is arranged at the end of the silicone sleeve body away from the silicone pad.

[0005] The working principle and advantages of the present invention are as follows: the silicone pad of the silicone sleeve of the present invention protrudes outside the sleeve, the silicone pad can isolate the bottle and the sleeve, so that the sleeve will not contact the bottle cap, the silicone pad can also be used for the screw-on operation of the bottle cap whose outer diameter is larger than the maximum outer diameter of the screw-on hole, and at the same time, the anti-slip pattern on the wall of the screw-on hole can not only increase the friction between the bottle cap and the silicone sleeve, but also, due to its special setting shape, can assist the bottle to separate from the silicone sleeve after the screw-on is completed; the present invention can prevent the sleeve from scratching the bottle body and the bottle cap, and it is convenient for the bottle to separate from the silicone sleeve after the screw-on is completed. At the same time, the setting of the locking piece can facilitate the disassembly and assembly of the silicone sleeve.

[0006] The anti-slip pattern on the wall of the screw cap hole can increase the friction between the bottle cap and the silicone sleeve when the cap is screwed, and it helps the bottle to detach from the silicone sleeve after the cap is screwed. The amplitude of the sine curve forming the anti-slip pattern changes evenly, and its variation range is between 0.1 and 1, among which the optimal variation range is 0.2-0.5. The sine curve forming the anti-slip pattern has no less than 8 cycles on the wall of the screw cap hole, which can not only provide the bottle cap with sufficient friction, but also provide sufficient thrust to make the bottle cap detach from the silicone sleeve when the silicone sleeve is screwed on. The vent hole also helps the bottle to fall off the silicone sleeve to avoid the space between the silicone sleeve and the bottle cap forming a negative pressure to adsorb the bottle cap.

[0007] Furthermore, the outer diameter of the sleeve is smaller than the outer diameter of the silicone pad.

[0008] The outer diameter of the silicone pad is larger than the outer diameter of the sleeve, and the sleeve can be completely separated from the bottle to prevent the sleeve from damaging the bottle. At the same time, the silicone pad can also be used to rotate bottle caps with larger diameters, thereby enhancing the versatility of the capping mechanism.

[0009] Furthermore, the sleeve includes a connecting block and a cylinder body, the connecting block and the cylinder body are fixedly connected, a locking plate groove is provided on the connecting block, and mounting holes for installing the silicone sleeve body and spline grooves for installing splines are provided in the connecting block and the cylinder body, and a locking groove connected to the locking plate groove is provided at the spline groove.

[0010] The sleeve is used to fix the shape of the silicone sleeve, enhance the rigidity of the silicone sleeve, and reduce the elastic deformation of the silicone sleeve.

[0011] Furthermore, the locking plate includes an arc-shaped plate and a card block, the card block is fixedly connected to the arc-shaped plate and is located on one side of the arc-shaped plate close to the center of the arc of the arc-shaped plate, the shape and size of the arc-shaped plate are coordinated with the shape and size of the locking plate groove, the arc-shaped plate of the locking plate is installed at the locking plate groove, and the card block passes through the lock groove at the spline groove and engages with the card groove on the key body of the spline.

[0012] The setting of the locking piece helps to quickly disassemble and assemble the silicone sleeve in the sleeve.

[0013] Furthermore, the pressure cover includes a connecting shaft and a cover body, wherein the connecting shaft is fixedly connected to the cover body, and a connecting hole for connecting to an external connecting shaft is provided on the connecting shaft, and the cover body is connected to the connecting block by threads.

[0014] The gland is used to connect the sleeve and the capping motor.

[0015] Furthermore, the number of the locking pieces is not less than two.

[0016] The number of locking pieces is no less than two, so as to more firmly fix the silicone sleeve in the sleeve.

[0017] Furthermore, the anti-slip pattern has a rotation direction of counterclockwise.

[0018] The anti-slip grooves set counterclockwise help the bottle to separate from the silicone sleeve after the cap is screwed on. BRIEF DESCRIPTION OF THE DRAWINGS

The amplitude of the sine curve forming the anti-skid pattern changes uniformly from 0.2 to 0.5 on the hole wall of the screw cap hole 45, and the period is 12.

[0033] like Figure 5 As shown, the sleeve 3 includes a connecting block 31 and a cylinder 32, the connecting block 31 and the cylinder 32 are fixedly connected, a locking plate groove 33 is provided on the connecting block 31, and a mounting hole 34 for installing the silicone sleeve body 41 and a spline groove 35 for installing the spline 43 are provided in the connecting block 31 and the cylinder 32, and a locking groove 36 connected to the locking plate groove 33 is provided at the spline groove 35.

[0034] like Figure 6 As shown, the locking piece 2 includes an arc-shaped piece 21 and a clamping block 22, the clamping block 22 is fixedly connected to the arc-shaped piece 21 and is located on one side of the arc-shaped piece 21 close to the center of its arc, the shape and size of the arc-shaped piece 21 are coordinated with the shape and size of the locking piece groove 33, the arc-shaped piece 21 of the locking piece 2 is installed at the locking piece groove 33, and the clamping block 22 passes through the locking groove 36 at the spline groove 35 and is engaged with the clamping groove 44 on the key body of the spline 43.

[0035] like Figure 2 As shown, the number of the locking pieces 2 is not less than two.

[0036] like Figure 4 As shown, the gland 1 includes a connecting shaft 11 and a cover body 12, wherein the connecting shaft 11 is fixedly connected to the cover body 12, and a connecting hole 13 for connecting to an external connecting shaft is provided on the connecting shaft 11, and the cover body 12 is connected to the connecting block 31 by threads.

[0037] The installation steps of the screw cap mechanism are as follows: first, place the silicone sleeve body 41 of the silicone sleeve 4 into the installation hole 34 of the sleeve 3, and during installation, the key body of the spline 43 outside the silicone sleeve body 41 is coordinated with the spline groove 35 inside the sleeve 3. After the silicone sleeve body 41 is installed in place, the locking piece 2 is installed in the locking piece groove 33 at the connecting block 31 of the sleeve 3, and the arc-shaped piece 21 of the locking piece 2 is installed at the locking piece groove 33. The clamping block 22 of the locking piece 2 passes through the locking groove 36 on the spline groove 35 and is inserted into the clamping groove 44 on the key body of the spline 43. Inside, fix the silicone sleeve 4 in the sleeve 3, and the number of locking plates 2 can be set according to actual needs; then install the pressure cap 1 on the sleeve 3, and the cover body 12 of the pressure cap 1 is connected to the connecting block 31 of the sleeve 3 through threads, and the cover body 12 restricts the locking plate 2 in the locking plate groove 33 so that the locking plate 2 will not fall off due to vibration, and then connect the connecting shaft 11 of the pressure cap 1 with the output shaft of the motor, insert the output shaft of the motor into the connecting hole 13 at the connecting shaft 11, and then fix the connecting shaft 11 to the output shaft of the motor with screws.

[0038] After the capping mechanism is installed on the capping machine, the capping machine can be started.

[0039] like Figure 8 As shown, the anti-slip pattern has a rotation direction of counterclockwise.

[0040] like Figure 7 As shown, the outer diameter of the sleeve 3 is smaller than the outer diameter of the silicone pad 42 .

[0041] When the bottle cap with a smaller diameter is screwed, the bottle cap and the bottle are placed in the screwing hole 45 at the silicone sleeve main body 41, and the screwing machine is started. The motor of the screwing machine drives the cap pressing 1 to rotate, the cap pressing 1 drives the sleeve 3 to rotate, the sleeve 3 drives the silicone sleeve 4 to rotate, and the silicone sleeve 4 drives the bottle cap to rotate; the anti-skid pattern at the hole wall of the screwing hole 45 in the silicone sleeve main body 41 can increase the friction between the bottle cap and the silicone sleeve 4, so that the silicone sleeve 4 is more firm and stable when screwing the bottle cap; when the screwing is finished, the anti-skid pattern formed by the sinusoidal curve sweeping arranged counterclockwise at the hole wall of the screwing hole 45 can push the bottle cap outward to the screwing hole 45, so that the bottle cap and the bottle are more easily separated from the silicone sleeve 4, and the vent hole 46 on the silicone sleeve 4 also helps the bottle to fall off from the silicone sleeve 4, so as to avoid the space between the silicone sleeve 4 and the bottle cap to form a negative pressure to adsorb the bottle cap; when the bottle cap with a larger diameter needs to be screwed, the bottle cap is fitted with the silicone pad 42 protruding from the sleeve 3, and then the screwing machine is started.

[0042] The silicone pad 42 of the silicone sleeve 4 of the present invention protrudes outside the sleeve 3, and the silicone pad 42 can isolate the bottle and the sleeve 3, so that the sleeve 3 will not contact the bottle cap, and the silicone pad 42 can also be used for the screw-on operation of the bottle cap whose outer diameter is larger than the maximum outer diameter of the screw-on hole 45. At the same time, the anti-slip pattern on the wall of the screw-on hole 45 can not only increase the friction between the bottle cap and the silicone sleeve, but also, due to its special setting shape, can assist the bottle to separate from the silicone sleeve 4 after the screw-on is completed. The present invention can prevent the sleeve 3 from causing scratches to the bottle body and the bottle cap, and it is convenient for the bottle to separate from the silicone sleeve 4 after the screw-on is completed. At the same time, the setting of the locking piece 2 can facilitate the disassembly and assembly of the silicone sleeve.
