[0002] During the toner filling production process, a special toner packaging bottle is required at the request of the customer. The bottle cap of this special packaging bottle is different from the aluminum film bottle cap that is previously sealed by tightening and heating. This bottle cap is directly pressed on the bottle mouth through an interference fit with the bottle mouth, achieving capping and sealing at one time. During the first batch of production practice, the production operator pressed the bottle cap by applying pressure with his bare hands.

[0003] This method has the following disadvantages: 1. The operator consumes a lot of physical energy during continuous bottling operations, and the production efficiency is low; 2. If the bottle body is not fixed stably when pressing the bottle cap, the bottle may fall over and scatter powder, polluting the workshop environment. Therefore, a special person is required to hold the bottle body, and two people operate and occupy the operator. 3. There have been cases where the bottle cap is not pressed in place, resulting in powder leakage from the bottle mouth during transportation, which has been complained by customers. 4. If too much force is used when pressing the cap, the special cap pre-installed on the bottom of the bottle by the customer will loosen and leak powder and the bottle will deform.

[0059] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0060] Example 1

[0061] like Figures 1 to 21 As shown, a special device for pressing the bottle cap of a toner packaging bottle in the embodiment of the first aspect of the utility model comprises a frame 1, a bottle body locking mechanism 2 and a bottle cap pressing mechanism 3, wherein the bottle body locking mechanism 2 and the bottle cap pressing mechanism 3 are both arranged on the top of the frame 1, and the frame 1 is welded by square tubes, and is used to carry the bottle body locking mechanism 2 and the bottle cap pressing mechanism 3, and maintain the working stability of the whole device;

[0062] The bottle body locking mechanism 2 includes a bottom plate assembly weldment 21, a lock plate pull rod assembly weldment 23 and a lock plate assembly weldment 25. The bottom plate assembly weldment 21 is arranged on the top of the frame 1. The lock plate pull rod assembly weldment 23 is slidably arranged on the bottom plate assembly weldment 21, and one end of the lock plate pull rod assembly weldment 23 extends outside the bottom plate assembly weldment 21. The other end of the lock plate pull rod assembly weldment 23 is connected with the lock plate assembly weldment 25. In the locked state, the lock plate assembly weldment 25 and the bottom plate assembly weldment 21 form a lock hole to lock the toner packaging bottle 4.

[0063] like Fig.21 As shown, the toner packaging bottle 4 includes a bottle cap 41, a bottle body 42, a bottom cover 43 and a bottle mouth 44, the bottom cover 43 is arranged at the bottom of the bottle body 42, the bottle mouth 44 is arranged at the top of the bottle body 42, the bottle cap 41 and the bottle mouth 44 are interference fit and press-fitted, and an annular groove 45 is arranged on the outer side wall of the bottle mouth 44, and the groove 45 is the locking position of the bottle body locking mechanism 2;

[0064] The bottle cap pressing mechanism 3 includes a pressing handle 31, a pressing plate 32 and a connecting rod 33. One end of the pressing handle 31 is hinged to the bottom plate assembly weldment 21. A connecting rod is provided on the top of the pressing plate 32. The connecting rod is hinged to the pressing handle 31. The two ends of the connecting rod 33 are respectively hinged to the bottom plate assembly weldment 21 and the connecting rod. The connecting rod 33 is parallel to the pressing handle 31. The pressing end of the pressing plate 32 is always vertically downward. When pressing, the pressing plate 32 is located directly above the bottle mouth. The pressing handle 31 uses the principle of lever to amplify the operating force of the pressing handle into the pressing force of the bottle cap. The pressing plate 32 transmits the pressing force to the bottle cap, thereby achieving the purpose of saving manpower during the pressing operation.

[0065] The press-fitting handle 31, the connecting rod 33, the pressing plate 32 and the first support 215 together form a hinged four-bar mechanism, which can convert the pressing force of the handle that makes a rotational motion when the press-fitting handle 31 is pressed down into the pressing force of the pressing plate that is always vertically downward, thereby achieving a smooth and reliable press-fitting of the bottle cap and avoiding the occurrence of powder leakage at the bottle mouth due to the skewed and inadequate press-fitting of the bottle cap.

[0066] In this embodiment, it should be noted that Figure 5 and Figure 6 As shown, the bottom plate assembly weldment 21 includes a bottom plate body 211, a limiting guide groove 214, a first support 215 and a second support 216. A locking plate hole 212 and a bottle mouth fixing hole 213 are provided in the middle of the bottom plate body 211. The locking plate hole 212 and the bottle mouth fixing hole 213 are connected to each other; the bottle mouth fixing hole 213 is U-shaped, the locking plate hole 212 is rectangular, and the opening of the bottle mouth fixing hole 213 faces the locking plate hole 212. The width of the locking plate hole 212 is greater than the diameter of the bottle mouth 44, and the width of the bottle mouth fixing hole 213 is slightly smaller than the diameter of the bottle mouth 44. The groove 45 provided on the outer wall of the bottle mouth 44 can be inserted into the bottle mouth fixing hole 213 to achieve preliminary positioning of the packaging bottle;

[0067] A limiting guide groove 214 is welded on both sides of the width direction of the top of the bottom plate body 211, and the limiting guide groove 214 is arranged along the length direction of the bottom plate body 211. Both sides of the lock plate assembly weldment 25 are slidably arranged in a limiting guide groove 214 respectively; by providing the limiting guide groove 214, it is possible to prevent the lock plate assembly weldment 25 from tipping forward and backward and the mechanism from getting stuck due to various driving forces when it moves forward and backward;

[0068] The first support 215 and the second support 216 are welded to the two ends of the bottom plate body 211 respectively, one end of the press handle 31 and one end of the connecting rod 33 are hinged to the first support 215, the press handle 31 can rotate around the first support 215, and the locking plate pull rod assembly weldment 23 is slidably connected to the second support 216;

[0069] The second support 216 can also serve as a downward pressure limit plate for the press-fit handle 31. Fig. 20 As shown, after the cap is pressed into place, a gap 217 (about 1 mm) exists between the pressing handle 31 and the limiting plate, and the pressing is continued to make the pressing handle 31 contact with the top of the second support 216; at this time, the pressing handle 31 undergoes elastic deformation to apply additional pressure to the bottle cap; this design effectively limits the operating force of the pressing handle 31 to a reasonable range, preventing the cap from not being in place due to insufficient operating force during capping, and also preventing excessive operating force from crushing the bottle mouth and damaging the capping device.

[0070] Furthermore, if Figures 10 to 12 As shown, the lock plate assembly weldment 25 includes a lock plate body 251, a locking end 252 and a third support 253. The lock plate body 251 is horizontally arranged, and both sides of the lock plate body 251 are respectively slidably arranged in a limiting guide groove 214. The locking end 252 and the third support 253 are respectively arranged at both ends of the lock plate body 251. The locking end 252 and the lock plate body 251 are an integral structure. The third support 253 is welded to the lock plate body 251. The end of the locking end 252 is provided with a locking hole. The locking hole is semicircular, and the opening direction of the locking hole is opposite to the opening direction of the bottle mouth fixing hole 213. In the locked state, the locking end 252 enters the locking plate hole 212 and forms a complete circular locking hole with the U-shaped bottle mouth fixing hole 213, thereby fixing the toner packaging bottle 4. During the press-fitting operation, the bottle bottom is suspended in the air, and the bottle bottom cover 43 and the bottle body 42 pre-installed on the bottle bottom are not subjected to force, thereby effectively protecting the packaging bottle from damage; the third support 253 is connected to one end of the locking plate pull rod assembly weldment 23;

[0071] Furthermore, if Figure 8 and Fig. 9As shown, the lock plate pull rod assembly weldment 23 includes a lock plate pull rod body 231, a sliding hole 232, an opening and closing lock guide hole 233 and a pull rod handle 234. The sliding hole 232 is in the shape of an elongated strip. The sliding hole 232 is arranged along the length direction of the lock plate pull rod body 231, and the sliding hole 232 is arranged in the middle of the lock plate pull rod body 231. The sliding hole 232 is slidably connected with the second support 216 through the pin shaft 24; the lock plate pull rod body 231 is connected with the base plate body 211 through the second support 216 and two pin shafts arranged on the base plate body 211, forming a linear sliding mechanism;

[0072] The opening and closing lock guide hole 233 is set at one end of the lock plate pull rod body 231, and a lock plate pin is provided on the third support 253, and the lock plate pin is slidably set in the opening and closing lock guide hole 233; the lock plate body 251 is connected with the opening and closing lock guide hole 233 set at one end of the lock plate pull rod body 231 through the lock plate pin on the third support 253, so that the lock plate pull rod body 231 can drive the lock plate body 251 to realize reciprocating motion.

[0073] The rod handle 234 is arranged at the other end of the lock plate rod body 231 , and the rod handle 234 is perpendicular to the lock plate rod body 231 . One end of the rod handle 234 is welded to the lock plate rod body 231 , and the outer sleeve of the rod handle 234 is provided with an anti-slip sleeve for the operator to hold easily.

[0074] Furthermore, the opening and closing lock guide hole 233 is used to control the opening and closing lock action of the lock plate assembly weldment 25, so that when the bottle body locking mechanism 2 is locked, the bottle body locking mechanism 2 will not be accidentally unlocked due to the reverse push of the bottle body shaking; the lock can only be unlocked by pulling the lock plate pull rod body 231; Fig.13 As shown, the inner wall of the unlocking and locking guide hole 233 includes a locking surface 2331, a locking driving surface 2332, a forward driving surface 2333, a backward driving surface 2334 and an unlocking driving surface 2335, and the locking surface 2331, the locking driving surface 2332, the forward driving surface 2333, the backward driving surface 2334 and the unlocking driving surface 2335 are sequentially connected end to end;

[0075] The unlocking driving surface 2335 is used to drive the lock plate body 251 to avoid interference with the bottle mouth 44 with the locking end 252 facing downward, and move out of the groove 45 obliquely upward;

[0076] The backward driving surface 2334 is used to continue to drive the lock plate body 251 to move backward until the lock hole is fully opened after the locking end 252 of the lock plate body 251 moves out;

[0077] The forward driving surface 2333 is used to push the lock plate body 251 to move forward so that the locking end 252 is close to the bottle mouth 44. The forward driving surface 2333 is perpendicular to the forward direction of the lock plate body 251, and does not generate a wedging force on the lock plate body 251, thereby reducing the operating force of the return stroke of the lock plate body 251.

[0078] When the lock plate body 251 is about to enter the lock plate hole 212, the locking driving surface 2332 uses the supporting point of the lock plate body 251 on the bottom plate body 211 as a torque, forcing the locking end 252 of the lock plate body 251 to rotate downward rapidly, avoiding the interference of the bottle mouth, and continuing to push the lock plate body 251 to completely enter the lock plate hole 212; at the same time, the locking driving surface 2332 guides the lock plate pin shaft into the locking surface 2331; further push the lock plate pull rod body 231 forward, the locking surface 2331 moves to above the lock plate pin shaft, and generates a vertical downward and horizontal forward locking pressing force on the lock plate body 251. At this time, the lock plate body 251 will not be rebounded and unlocked due to the pressure during the capping or the shaking of the bottle, and can only be unlocked manually by pulling the lock plate pull rod body 231 backward.

[0079] The unlocking and locking principles of the bottle locking mechanism 2 of the entire device are as follows:

[0080] After the bottle locking mechanism 2 is unlocked, the toner packaging bottle 4 can be loaded or removed, and the unlocking action is divided into an "unlocking stroke" and a "retracting stroke".

[0081] The unlocking stroke of the bottle locking mechanism 2 is as follows: Fig.14 As shown, the lock plate pull rod body 231 is pulled horizontally to the left in the unlocking direction a by the pull rod handle 234, and the lock plate pin shaft is subjected to the unlocking driving force b toward the upper left under the action of the unlocking driving surface 2335 of the unlocking and closing lock guide hole 233, thereby driving the locking end 252 of the lock plate assembly weldment 25 to rotate downward and move toward the upper left, withdraw from the groove 45 of the toner packaging bottle 4, and enter the backward stroke;

[0082] The backward stroke of the bottle locking mechanism 2 is as follows: Fig.15 As shown, the lock plate pull rod body 231 moves in the horizontal leftward retreat direction c until the lock plate pin abuts against the retreat driving surface 2334 of the opening and closing lock guide hole 233 and is subjected to the horizontal leftward retreat driving force d, thereby driving the locking end 252 of the lock plate assembly weldment 25 to retreat until the lock plate assembly weldment 25 is fully opened (i.e., exits the lock plate hole 212);

[0083] The bottle locking mechanism 2 can lock the toner packaging bottle 4 after being locked, and the locking action is divided into a "forward stroke", a "locking stroke" and a "locking surface stroke".

[0084] The forward stroke of the bottle locking mechanism 2 is as follows: Fig.16As shown, the lock plate pull rod body 231 moves along the horizontal rightward advancing direction e until the lock plate pin abuts against the advancing driving surface 2333 of the opening and closing lock guide hole 233, and is subjected to the horizontal rightward advancing driving force f, thereby driving the locking end 252 of the lock plate assembly weldment 25 to advance toward the bottle mouth 44, and the advancing driving surface 2333 is perpendicular to the advancing direction of the lock plate assembly weldment 25, and does not generate a wedging force on the lock plate assembly weldment 25, thereby reducing the operating force of the forward stroke;

[0085] The locking stroke of the bottle locking mechanism 2 is as follows: Fig.17 As shown, the lock plate pull rod body 231 is pushed horizontally to the right in the locking direction g by the pull rod handle 234, and the lock plate pin shaft is subjected to the locking driving force h toward the lower right under the action of the locking driving surface 2332 of the opening and closing lock guide hole 233, until the lock plate pin shaft abuts against the locking surface 2331 of the opening and closing lock guide hole 233, thereby driving the locking end 252 of the lock plate assembly weldment 25 to be inserted into the groove 45 of the toner packaging bottle 4 for locking; in the locking stroke, when the lock plate assembly weldment 25 is about to enter the lock plate hole 212, the locking driving surface 2332 uses the supporting point of the lock plate body 251 on the bottom plate body 211 as a torque, forcing the locking end 252 to rotate downward quickly to avoid the interference of the bottle mouth 44, and continue to push the lock plate pull rod body 231, and the lock plate body 251 completely enters the lock plate hole 212; at the same time, the locking driving surface 2332 guides the lock plate pin shaft into the locking surface stroke;

[0086] The locking surface travel of the bottle body locking mechanism 2 is as follows Fig.18 As shown, during the locking surface stroke, the pull rod handle 234 is further pushed forward, and the locking surface 2331 moves to above the lock plate pin shaft. The lock plate pin shaft is subjected to a locking pressing force i vertically downward and horizontally to the right under the action of the locking surface 2331 of the opening and closing lock guide hole 233, so that the locking end 252 of the lock plate assembly 25 is pressed against the bottle mouth 44 of the toner packaging bottle 4. At this time, the lock plate body 251 will not be rebounded and unlocked due to the pressure during the capping or the shaking of the bottle, and can only be unlocked manually by pulling the lock plate pull rod body 231 backward.

[0087] The technical effect achieved by this embodiment is as follows: by setting the frame 1, the bottle body locking mechanism 2 and the bottle cap pressing mechanism 3, the frame 1 provides support for the entire device. During use, the bottle body locking mechanism 2 can be used to fix the bottle body of the toner packaging bottle 4, and then the bottle cap 41 can be placed on the bottle mouth 44. Then, the bottle cap pressing mechanism 3 can be used to press the bottle cap 41 onto the bottle mouth 44. The entire device is easy to operate, and a single person can complete the entire pressing operation.

[0088] Example 2

[0089] like Figures 1 to 21 As shown, this embodiment provides another special device for pressing the cap of a toner packaging bottle, and its structure includes all the contents of the embodiment 1, and only the different parts are described below.

[0090] In this embodiment, the lock plate pull rod assembly weldment 23 also includes a lock plate limit plate 235, which is arranged along the length direction of the lock plate pull rod body 231, and the lock plate limit plate 235 is perpendicular to the lock plate pull rod body 231, and the lock plate limit plate 235 is welded to the lock plate pull rod body 231.

[0091] In this embodiment, a safety lock plate 22 is also included. The safety lock plate 22 includes a lock plate body 221, a hook head 222 and a rotating hole 223. The hook head 222 and the rotating hole 223 are respectively arranged at two ends of the lock plate body 221. The rotating hole 223 is hinged to the first support 215 through a pin shaft 24, and the safety lock plate 22 can rotate around the first support 215.

[0092] In this embodiment, it should be noted that the positions of the pull rod handle 234 and the safety lock piece 22 are designed according to ergonomics to facilitate quick single-handed operation. Fig.18 As shown, after the lock plate pull rod body 231 pushes the lock plate assembly 25 into place to clamp the bottle mouth 44, that is, the bottle body locking mechanism 2 is in a locked state, the hook head 222 can just hook the left end of the lock plate limit plate 235, thereby preventing the lock plate pull rod body 231 from moving to the left due to misoperation, causing the bottle body locking mechanism 2 to be unlocked and causing the toner packaging bottle 4 to fall off.

[0093] The technical effect achieved by this embodiment is as follows: by setting the safety lock piece 22, after the lock plate pull rod body 231 is pushed forward into place, the safety lock piece 22 can fall freely to hook the lock plate pull rod body 231. This design can effectively prevent erroneous operations such as inadequate locking and accidental retreat of the lock plate pull rod body 231, and forms a double insurance with the locking surface 2331 on the opening and closing lock guide hole 233, thus preventing the phenomenon of packaging bottles falling off and scattering powder during the capping operation.

[0097] In this embodiment, it should be noted that after the press-fitting handle 31 is pressed down, the tension spring 34 is in a stretched state.

[0098] The technical effect achieved by this embodiment is that by providing the tension spring 34, after the press-fitting handle 31 is pressed down, the press-fitting handle 31 is released, and the press-fitting handle 31 is automatically reset under the elastic force of the tension spring 34, so that the press-fitting handle automatically returns to the initial position (such as Fig.19 As shown in the figure, when loading and unloading the toner packaging bottle, there is no need to manually lift the bottle cap pressing mechanism, making the operation of the entire device more labor-saving and convenient.

[0099] During use, the specific pressing steps of the entire device are as follows:

[0100] 1. Hold the lever handle 234 with your right hand and lift the safety lock plate 22 with your thumb;

[0101] 2. Pull the pull rod handle 234 backward to open the bottle body locking mechanism 2;
