Description

Technical Field

[0001] The present invention relates to an improved invention of packaging equipment, in particular to a fragrance ball assembly mechanism. Background Art

[0002] Daily-use scent balls such as cleaning balls and deodorizing pills are spherical in shape. These scent balls are packaged in hollow plastic shells. For example, publication number CN204246054U, invention name "A hanging toilet cleaning ball"; publication number CN208777401U, invention name "A toilet cleaning pendant", etc., disclose the packaging of cleaning balls. The plastic shell has two hemispherical cavities. When unfolded, the two cavities are adjacent to each other, and the two cavities are symmetrically provided with matching snap-fit ​​protrusions or grooves around them. The plastic shell is folded along the center line of the two cavities, and the folded plastic shells are snapped together. The two cavities are combined into a spherical cavity for packaging the scent balls. Currently, these scent balls are manually packaged, but manual packaging has the problems of low efficiency and high labor costs. Summary of the Invention

[0003] In view of the technical problems existing in the background technology, the technical problem solved by the present invention is to provide a fragrance ball assembly mechanism to realize the automatic assembly of fragrance balls.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solution: the incense ball assembly mechanism is characterized by comprising a mold base, a pre-folding component and a folding component,

[0005] The mold base is provided with a groove matching the shell, the groove includes a hemispherical first groove and a second groove, and the first groove is provided with a through hole that passes through the mold base from top to bottom;

[0006] The pre-folding component includes a first material stopper and a first material pusher that can be lifted up and down, wherein the first material stopper is arranged just above the groove except the first slot, and the first material pusher is arranged just below the through hole;

[0007] The folding component includes a pressing piece that moves up and down, and the pressing piece is above the second groove.

[0008] Folding the housing 180 degrees is a two-step process: pre-folding and press-folding. During pre-folding, the first stopper presses the housing from above, while the first push-up member pushes the first cavity of the housing from below, causing it to fold upward and gradually toward the second cavity. During press-folding, the presser moves downward and presses the first cavity, forcing it to mate with the second cavity, closing the two.

[0009] Preferably, the folding member further includes a second stopper that rises and falls, the second stopper being positioned directly above the recess, excluding the first and second recesses. During folding, the second stopper presses against the housing, excluding the cavity, to secure the housing. This prevents the housing from swinging, tilting, or shifting due to lack of force during folding, while also maintaining the closure of the first and second cavities, thereby improving assembly quality.

[0010] Preferably, the folding component further includes a second lifting member that rises and falls, and the second lifting member is disposed directly below the through hole; during folding, the second stopper moves downward to press the shell, and the second lifting member passes through the through hole from bottom to top and pushes upward against the first cavity portion of the shell, causing the first cavity portion of the shell to fold toward the second cavity portion, and then the pressing member moves downward and presses down on the first cavity portion of the shell, closing the first cavity portion and the second cavity portion of the shell. After pre-folding, if the first cavity portion of the shell rebounds, the second lifting member causes the first cavity portion of the shell to flip toward the second cavity portion again, ensuring that the pressing member moves downward to act on the first cavity portion, causing it to close with the second cavity portion.

[0011] Preferably, a secondary loading station is provided between the pre-folding station and the press-folding station, and the first material stop is positioned directly above the second cavity of the recess and offset from the second cavity loaded at the loading station. The second cavity of the housing is loaded twice, leaving an empty space after the first loading. The first material stop presses against the empty space, preventing the second cavity from being lifted during pre-folding, thereby facilitating the folding of the first cavity.

[0012] Preferably, the groove further comprises a hanging groove, and the second material stopper is arranged just above the hanging groove. When folding, the second material stopper presses the hook, which can not only press the shell but also does not hinder the folding of the first cavity part.

[0013] Preferably, the through hole is expanded to the first groove of the entire groove, providing more space for the first and second ejecting parts, facilitating debugging operations.

[0014] Preferably, the pressing member includes a pressing plate, and a pushing portion extends obliquely downward from the end of the pressing plate facing the second groove. When the pressing plate presses down on the first cavity portion of the housing, the inclined pushing portion acts obliquely on the first cavity portion, causing the first cavity portion to be pressed toward the second cavity portion of the housing.

[0015] Preferably, the mold base is installed on a transmission chain, and the mold base passes through a feeding station, a pre-folding station, and a press-folding station in sequence; the pre-folding component is arranged at the pre-folding station, and the press-folding component is arranged at the press-folding station.

DETAILED DESCRIPTION

[0021] The following describes the details and working principles of the embodiments and examples of the present invention in conjunction with the accompanying drawings. This incense ball assembly mechanism includes a mold base 1, a pre-folding component 10, and a folding component 20. Several mold bases 1 are installed on a transmission chain. The transmission chain is driven in an annular cycle. The mold bases 1 pass through the lower shell station 2, the feeding station 3, the pre-folding station 4, and the folding station 6 in sequence. See the attached Figure 4The shell 30 has a first cavity portion 31, a second cavity portion 32 and a hanging portion 33. The surface of the mold base 1 is provided with a groove 7 that matches the shell, and the groove 7 includes a hemispherical first groove, a second groove and a hanging groove. The first groove is provided with a through hole that passes through the mold base 1 up and down. The through hole can be expanded to the first groove of the entire groove 7, providing more space for the first ejecting member 11 and the second ejecting member 21. The pre-folding component 10 is arranged at the pre-folding station 4, and the pre-folding component 10 includes a first stopper 12 and a first ejecting member 11 that rise and fall. The first stopper 12 is arranged directly above the groove except the first groove, and the first ejecting member 11 is arranged directly below the through hole. The folding component 20 is arranged at the folding station 6, and the folding component 20 includes a pressing member that rises and falls, and the pressing member is directly above the second groove. At the lower shell station 2, the shell 30 is placed in the groove 7 of the mold base 1, and then the mold base 1 moves to the feeding station 3, and the fragrance ball is placed in the second cavity part 32 of the shell 30. The mold base 1 moves again and sends the shell 30 with the fragrance ball to the pre-folding station 4, the first stopper 12 moves down to press the shell 30, and the first lifting member 11 pushes the first cavity part 31 of the shell 30 from bottom to top. Because the shell 30 is folded by the first stopper 12, only the first cavity part 31 of the shell 30 is folded upward and gradually toward the second cavity part 32 of the shell 30. After the pre-folding is completed, the first stopper 12 moves up and the first lifting member 11 moves down and reset; then enters the folding station 6, the pressing member moves down and presses the first cavity part 31 of the shell 30, so that it is pressed together with the second cavity part 32 of the shell 30, and the two are closed to complete the assembly operation of the fragrance ball.

[0022] Because the plastic has a certain hardness, the force exerted by the first ejecting member 11 on the first cavity portion 31 is relatively large. To prevent the second cavity portion 32 of the shell 30 from being pulled upward, it is preferable that the first stopper 12 presses on the second cavity portion 32 of the shell. In order to facilitate the first stopper 12 to press on the second cavity portion 32 of the shell, a secondary feeding station 3 is provided between the pre-folding station 4 and the folding station 6. The first stopper is provided directly above the second cavity of the groove 7 and is staggered with the second cavity fed by the feeding station 3. That is, the fragrance balls are fed twice, and the feeding station 3 is the first feeding. At this time, the second cavity portion 32 is not full of fragrance balls and there is an empty space. During pre-folding, the first stopper 12 presses on the empty space of the second cavity portion 32. In this way, the second cavity portion 32 stays stably in the second groove and will not be lifted upward. The first cavity portion 31 is folded toward the second cavity portion 32 under the push of the first ejecting member 11. The secondary feeding station 3 fills the second cavity portion 32 with the fragrance ball. At this time, the first cavity portion 31 and the second cavity portion 32 are closed to cover the fragrance ball.

[0023] In order to ensure that the first cavity portion 31 and the second cavity portion 32 are pressed together when the pressing member is pressed down, the first cavity portion 31 must be inclined toward the second cavity portion 32, and the angle between the two is usually less than 60 degrees. After pre-folding, the first cavity portion 31 will rebound. The angle between the first cavity portion 31 and the second cavity portion 32 of the housing 30 is greater than 90 degrees. At this time, there is only the second cavity portion 32 directly below the pressing member. To ensure that the folding operation is completed smoothly, the folding component 20 also includes a second stopper 22 and a second top material member 21 that are lifted up and down. The second top material member 21 is arranged directly below the through hole. The second stopper 22 is arranged directly above the groove except the first groove and the second groove. During folding, the second stopper 22 presses other parts of the housing 30 except the cavity, so that the housing 30 can be pressed down to prevent the housing 30 from being lifted up without hindering the pressing of the first cavity portion 31 and the second cavity portion 32. Because the shell 30 is provided with a hanging portion 33, the second stopper 22 is arranged directly above the hanging groove. The second stopper 22 presses the hanging portion 33. Then, the second lifting member 21 passes through the through hole from bottom to top and pushes upward against the first cavity portion 31 of the shell, causing the first cavity portion 31 of the shell to fold toward the second cavity portion 32. Then, the pressing member moves downward and presses down the first cavity portion 31 of the shell, closing the first cavity portion 31 and the second cavity portion 32 of the shell. After pre-folding, the first cavity portion 31 of the shell has a rebound problem. The second lifting member 21 causes the first cavity portion 31 of the shell to fold toward the second cavity portion 32 again, ensuring that the pressing member moves downward to act on the first cavity portion 31, closing it with the second cavity portion 32. The first stopper 12, the second stopper 22, the first lifting member 11, the second lifting member 21 and the pressure member can be push rods or push plates, etc., and can be driven up and down by a cylinder. The pressing member includes a pressing plate 23, and a pushing portion 24 is extended downwardly at the end of the pressing plate 23 facing the second groove. The surface of the shell 30 is spherical. The design of the pushing portion 24 prevents the two from sliding when the pressing plate 23 presses down the shell 30. At the same time, when the pressing plate 23 presses down the first cavity portion 31 of the shell, the inclined pushing portion 24 acts obliquely on the first cavity portion 31, pushing the first cavity portion 31 toward the second cavity portion 32 of the shell 30 for better pressing effect.

[0024] The following further illustrates the working principle of the preferred embodiment with reference to the accompanying drawings: The mold base 1 sequentially passes through station 2 of the lower housing 30, the feeding station 3, the pre-folding station 4, the secondary feeding station 3, and the folding station 6. The mold base 1 moves to station 2 of the lower housing 30, where the housing 30 is placed into the groove 7. The mold base 1 then moves to the feeding station 3, where the first feeding occurs. Incense balls are then placed into the second cavity 32 of the housing 30, which is partially filled with material but has some empty space. The mold base 1 then moves to the pre-folding station 4, where the first stopper 12 moves downward and presses against the empty space in the second cavity 32, holding the housing 30 in place. The first push-up member 11 pushes the first cavity 31 of the housing 30 upward, folding it toward the second cavity 32. After the pre-folding is complete, the first push-up member and the first stopper return to their original positions, and the mold base 1 moves to the secondary feeding station 3, where the remaining empty space in the second cavity 32 is filled with incense balls. Then the mold base 1 moves to the folding station 6, the second stopper 22 moves down and presses the hanging part 33, and the second top member 21 pushes the first cavity part 31 of the shell 30 upward so that it leans against the second cavity part 32. At this time, the pressing plate 23 moves down and pushes the first cavity part 31 so that the first cavity part 31 is pressed against the second cavity part 32 until the two are closed, thus completing the packaging.
