Description

Technical Field

[0001] This invention relates to the field of toner production equipment technology, specifically to a special device for pressing caps onto toner packaging bottles. Background Technology

[0002] During the toner filling process, a special toner packaging bottle was required by the customer. The cap of this special bottle differs from the previous aluminum foil caps that were screwed on and heated for sealing. This cap is directly press-fitted onto the bottle neck via an interference fit, achieving capping and sealing in one step. In the initial production practice, production operators applied pressure manually to press the caps on.

[0003] This method has the following disadvantages: 1. Continuous bottling operations require significant physical exertion from operators, resulting in low production efficiency. 2. If the bottle is not securely fixed during capping, it may tip over and spill powder, polluting the workshop environment. Therefore, a dedicated person is required to hold the bottle, and two people are needed for operation, occupying operator time. 3. There have been instances where improper capping has led to powder leakage during transportation, resulting in customer complaints. 4. Excessive force during capping can cause the pre-installed seal at the bottom of the bottle to loosen, leading to powder leakage and bottle deformation.

[0004] Therefore, how to design a device that can easily and reliably press-fit bottle caps and securely fix and protect the bottle body has become an urgent problem to be solved. Summary of the Invention

[0005] Therefore, the present invention provides a special device for pressing caps onto toner packaging bottles to solve the above-mentioned problems in the prior art.

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

[0007] According to a first aspect of the present invention, a special device for pressing caps onto toner packaging bottles includes a frame, a bottle locking mechanism, and a cap pressing mechanism, wherein the bottle locking mechanism and the cap pressing mechanism are both disposed on the top of the frame.

[0008] The bottle locking mechanism includes a base plate assembly, a locking plate pull rod assembly, and a locking plate assembly. The base plate assembly is located on the top of the frame.

[0015] The lock opening and closing guide hole is provided at one end of the lock plate pull rod body, and the lock plate pin is provided on the third support. The lock plate pin is slidably disposed in the lock opening and closing guide hole.

[0016] The lever handle is located at the other end of the locking plate lever body, and the lever handle is perpendicular to the locking plate lever body.

[0017] Furthermore, the inner wall of the locking / unlocking guide hole includes a locking surface, a locking driving surface, a forward driving surface, a backward driving surface, and an unlocking driving surface, which are connected end to end in sequence.

[0018] Furthermore, the locking plate tie rod assembly also includes a locking plate limiting plate, which is arranged along the length direction of the locking plate tie rod body and is perpendicular to the locking plate tie rod body.

[0059] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort 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 bottle caps on toner packaging bottles according to a first aspect embodiment of the present invention includes a frame 1, a bottle locking mechanism 2 and a bottle cap pressing mechanism 3. The bottle locking mechanism 2 and the bottle cap pressing mechanism 3 are both located on the top of the frame 1. The frame 1 is welded from square tubes and is used to support the bottle locking mechanism 2 and the bottle cap pressing mechanism 3 and maintain the stability of the entire device during operation.

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

[0063] like Figure 21 As shown, the toner packaging bottle 4 includes a bottle cap 41, a bottle body 42, a bottom cap 43, and a bottle mouth 44. The bottom cap 43 is located at the bottom of the bottle body 42, and the bottle mouth 44 is located at the top of the bottle body 42. The bottle cap 41 and the bottle mouth 44 are press-fitted together. An annular groove 45 is provided on the outer side wall of the bottle mouth 44. 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 base plate assembly 21. The top of the pressing plate 32 is provided with a connecting rod, which is hinged to the pressing handle 31. Both ends of the connecting rod 33 are respectively hinged to the base plate assembly 21 and the connecting rod, and the connecting rod 33 is parallel to the pressing handle 31. The pressing end of the pressing plate 32 is always vertically downward, and the pressing plate 32 is located directly above the bottle mouth during pressing. The pressing handle 31 uses the lever principle to amplify the operating force of pressing the 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 pressing handle 31, connecting rod 33, pressing plate 32 and first support 215 together form a four-bar linkage mechanism. The four-bar linkage mechanism can convert the pressing force of the handle 31, which rotates when pressed down, into the pressing force of the pressing plate, which is always vertically downward, thereby realizing the stable and reliable pressing of the bottle cap and avoiding the phenomenon of powder leakage from the bottle mouth caused by the bottle cap being misaligned.

[0066] In this embodiment, it should be noted that, as Figure 5 and Figure 6 As shown, the base plate assembly 21 includes a base plate body 211, a limiting guide groove 214, a first support 215, and a second support 216. The base plate body 211 has a locking plate hole 212 and a bottle mouth fixing hole 213 in the middle, and the locking plate hole 212 and the bottle mouth fixing hole 213 are interconnected. The bottle mouth fixing hole 213 is U-shaped, and the locking plate hole 212 is rectangular. 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 on the outer wall of the bottle mouth 44 can be inserted into the bottle mouth fixing hole 213 to achieve the initial positioning of the packaging bottle.

[0067] A limiting guide groove 214 is welded to each of the two sides of the top width direction of the base plate body 211. The limiting guide groove 214 is set along the length direction of the base plate body 211. The two sides of the locking plate assembly 25 are slidably set in a limiting guide groove 214. By setting the limiting guide groove 214, it is possible to prevent the locking plate assembly 25 from tilting back and forth and jamming due to various driving forces when it moves back and forth.

[0068] The first support 215 and the second support 216 are respectively welded to both ends of the base plate body 211. One end of the press-fit handle 31 and one end of the connecting rod 33 are both hinged to the first support 215. The press-fit handle 31 can rotate around the first support 215. The locking plate tie rod assembly 23 is slidably connected to the second support 216.

[0069] The second support 216 can also serve as a pressing limit plate for the press-fit handle 31, such as Figure 20 As shown, after the cap is in place, a gap 217 (about 1 mm) is created between the pressing handle 31 and the limiting plate. Pressing down further causes the pressing handle 31 to contact the top of the second support 216. At this time, the pressing handle 31 undergoes elastic deformation, applying additional pressure to the bottle cap. This design effectively limits the operating force of the pressing handle 31 to a reasonable range, preventing insufficient operating force from causing the cap to not be in place, and also preventing excessive operating force from damaging the bottle mouth and the capping device.

[0070] Furthermore, such as Figures 10 to 12 As shown, the locking plate assembly 25 includes a locking plate body 251, a locking end 252, and a third support 253. The locking plate body 251 is horizontally arranged, and its two sides are slidably disposed within a limiting guide groove 214. The locking end 252 and the third support 253 are respectively disposed at both ends of the locking plate body 251. The locking end 252 and the locking plate body 251 are integrally formed, and the third support 253 is welded to the locking plate body 251. The end of the locking end 252 is provided with a locking hole. The locking hole is semi-circular, and the opening of the locking hole faces the opening 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 to fix the toner packaging bottle 4. During the pressing operation, the bottom of the bottle is suspended, and the bottom cap 43 and the bottle body 42 pre-installed on the bottom of the bottle are not subjected to force, effectively protecting the packaging bottle from damage; the third support 253 is connected to one end of the locking plate pull rod assembly welded part 23;

[0071] Furthermore, such as Figure 8 and Figure 9As shown, the locking plate pull rod assembly 23 includes a locking plate pull rod body 231, a sliding hole 232, an opening and closing guide hole 233, and a pull rod handle 234. The sliding hole 232 is elongated and is arranged along the length of the locking plate pull rod body 231, and is located in the middle of the locking plate pull rod body 231. The sliding hole 232 is slidably connected to the second support 216 through a pin 24. The locking plate pull rod body 231 is connected to the base plate body 211 through the second support 216 and two pins arranged on the base plate body 211, forming a linear sliding mechanism.

[0072] The locking guide hole 233 is provided at one end of the locking plate pull rod body 231. The third support 253 is provided with a locking plate pin, which is slidably disposed in the locking guide hole 233. The locking plate body 251 is connected to the locking guide hole 233 at one end of the locking plate pull rod body 231 through the locking plate pin on the third support 253, so that the locking plate pull rod body 231 can drive the locking plate body 251 to achieve reciprocating motion.

[0073] The lever handle 234 is located at the other end of the locking plate lever body 231. The lever handle 234 is perpendicular to the locking plate lever body 231. One end of the lever handle 234 is welded to the locking plate lever body 231. The lever handle 234 is covered with an anti-slip sleeve for easy gripping by the operator.

[0074] Furthermore, the locking / unlocking guide hole 233 is used to control the locking / unlocking action of the lock plate assembly 25, ensuring that the bottle locking mechanism 2 will not be accidentally unlocked due to reverse pushing caused by bottle shaking when it is in the locked state; unlocking can only be achieved by pulling the lock plate lever body 231; such as Figure 13 As shown, the inner wall of the locking / unlocking 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. 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 connected end to end in sequence.

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

[0076] The backward-moving surface 2334 is used to continue to move the lock plate body 251 backward until the lock hole is fully opened after the locking end 252 of the lock plate body 251 is moved out.

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

[0078] As the locking plate body 251 is about to enter the locking plate hole 212, the locking driving surface 2332 uses the support point of the locking plate body 251 on the base plate body 211 as torque, forcing the locking end 252 of the locking plate body 251 to rotate and descend rapidly, avoiding interference from the bottle mouth, and continue to push the locking plate body 251 to fully enter the locking plate hole 212; at the same time, the locking driving surface 2332 guides the locking plate pin into the locking surface 2331; further pushing the locking plate lever body 231 forward, the locking surface 2331 moves above the locking plate pin, generating a vertically downward and horizontally forward locking pressure on the locking plate body 251. At this time, the locking plate body 251 will not be rebounded and unlocked due to the pressure during capping or the shaking of the bottle, and can only be unlocked manually by pulling the locking plate lever body 231 backward.

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

[0080] After the bottle locking mechanism 2 is unlocked, the toner packaging bottle 4 can be inserted or removed. The unlocking action is divided into "unlocking stroke" and "reverse stroke".

[0081] The unlocking stroke of the bottle locking mechanism 2 is as follows: Figure 14 As shown, by pulling the lever handle 234 along the horizontal leftward unlocking direction a, the lock plate lever body 231 is pulled. Under the action of the unlocking driving surface 2335 of the lock opening and closing guide hole 233, the lock plate pin is subjected to the unlocking driving force b towards the upper left, thereby driving the locking end 252 of the lock plate assembly 25 to rotate downward and move to the upper left, exiting from the groove 45 of the toner packaging bottle 4 and entering the backward stroke.

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

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

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

[0085] The locking stroke of the bottle locking mechanism 2 is as follows: Figure 17 As shown, by pushing the locking plate lever body 231 in the horizontal rightward locking direction g through the lever handle 234, the locking plate pin is subjected to a locking force h towards the lower right under the action of the locking driving surface 2332 of the lock opening and closing guide hole 233, until the locking plate pin abuts against the locking surface 2331 of the lock opening and closing guide hole 233, thereby driving the locking end 252 of the locking plate assembly 25 to be inserted into the groove 45 of the toner packaging bottle 4 for locking; during the locking stroke, when the locking plate assembly 25 is about to enter the locking plate hole 212, the locking driving surface 2332 uses the support point of the locking plate body 251 on the base plate body 211 as the torque, forcing the locking end 252 to rotate and descend rapidly to avoid interference from the bottle opening 44, and continue to push the locking plate lever body 231, so that the locking plate body 251 is completely inserted into the locking plate hole 212; at the same time, the locking driving surface 2332 guides the locking plate pin into the locking surface stroke;

[0086] The travel of the locking surface of the bottle locking mechanism 2 is as follows: Figure 18 As shown, during the locking surface stroke, the lever handle 234 is pushed forward further, and the locking surface 2331 moves above the locking plate pin. Under the action of the locking surface 2331 of the lock guide hole 233, the locking plate pin is subjected to a vertical downward and horizontal rightward locking pressure i, so that the locking end 252 of the locking plate assembly 25 presses against the bottle mouth 44 of the toner packaging bottle 4. At this time, the locking plate body 251 will not be rebounded and unlocked due to the pressure during capping or the shaking of the bottle. It can only be unlocked manually by pulling the locking plate lever body 231 backward.

[0087] The technical effects achieved in this embodiment are as follows: By setting up a frame 1, a bottle locking mechanism 2, and a cap pressing mechanism 3, the frame 1 provides support for the entire device. During use, the bottle body of the toner packaging bottle 4 can be fixed by the bottle locking mechanism 2, and the cap 41 can be placed at the bottle mouth 44. Then, the cap pressing mechanism 3 can press the cap 41 onto the bottle mouth 44. The entire device is simple to operate, and a single person can complete the entire pressing operation. It has low labor intensity, high work efficiency, and can complete the pressing operation quickly and efficiently. The entire device uses a mechanical structure to complete the pressing operation, which can ensure the uniformity of the pressing operation force and effectively ensure the pressing quality.

[0088] Example 2

[0089] like Figures 1 to 21 As shown in the figure, another special device for pressing caps on toner packaging bottles provided in this embodiment has the same structure as in embodiment 1. Only the different parts are described below.

[0090] In this embodiment, the locking plate tie rod assembly 23 further includes a locking plate limiting plate 235, which is arranged along the length direction of the locking plate tie rod body 231 and is perpendicular to the locking plate tie rod body 231. The locking plate limiting plate 235 is welded to the locking plate tie 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 disposed at both ends of the lock plate body 221. The rotating hole 223 is hinged to the first support 215 through a pin 24. 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 lever handle 234 and the safety lock plate 22 are ergonomically designed for easy and quick one-handed operation. Figure 18 As shown, after the locking plate lever body 231 pushes the locking plate assembly 25 into place and locks the bottle mouth 44, the bottle locking mechanism 2 is in the locked state. The hook head 222 can just hook the left end of the locking plate limiting plate 235, thereby preventing the locking plate lever body 231 from moving to the left due to misoperation, causing the bottle locking mechanism 2 to be unlocked and the toner packaging bottle 4 to fall off.

[0093] The technical effect achieved by this embodiment is as follows: by setting the safety locking piece 22, after the locking plate pull rod body 231 is pushed forward to the position, the safety locking piece 22 can fall freely and hook the locking plate pull rod body 231. This design can effectively prevent misoperation such as incomplete locking and accidental backward movement of the locking plate pull rod body 231. It forms a double insurance with the locking surface 2331 on the opening and closing guide hole 233, eliminating the phenomenon of packaging bottles falling off and spilling powder during capping operations.

[0094] Example 3

[0095] like Figures 1 to 21 As shown in the figure, another special device for pressing caps on toner packaging bottles provided in this embodiment has the same structure as in embodiment 2. Only the different parts are described below.

[0096] In this embodiment, the bottle cap pressing mechanism 3 also includes a tension spring 34. One end of the tension spring 34 is connected to the end of the pressing handle 31 away from its grip, and the other end of the tension spring 34 is connected to the frame 1.

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

[0098] The technical effect achieved by this embodiment is as follows: by setting the tension spring 34, after pressing down the pressing handle 31 and releasing the pressing handle 31, the pressing handle 31 can automatically reset under the elastic force of the tension spring 34, so that the pressing handle automatically returns to its initial position (e.g., Figure 19 As shown in the figure, there is no need to manually lift the cap pressing mechanism when loading and unloading toner packaging bottles, making the operation of the entire device more labor-saving and convenient.

[0099] During use, the specific pressing operation 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 lever handle 234 backward to open the bottle locking mechanism 2;

[0102] 3. Place the toner packaging bottle 4 that needs to be pressed into the U-shaped bottle mouth fixing hole 213 of the bottle locking mechanism 2;

[0103] 4. Pushing the lever handle 234 forward will lock the bottle opening 44 with the locking end 252 and confirm that the safety locking piece 22 falls back into place under its own weight.

[0104] 5. Place the bottle cap 41 at the bottle opening 44, then press down the pressing handle 31 to the bottom, and the bottle cap 41 will be pressed into place.

[0105] 6. Pull the lever handle 234 back again to remove the pressed toner packaging bottle 4, completing the pressing operation.

[0106] Although the present invention has been described in detail above with general descriptions and specific embodiments, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.

[0107] The terms such as "upper," "lower," "left," "right," and "middle" used in this specification are merely for clarity of description and are not intended to limit the scope of the invention. Any changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.
