Description

Technical Field

[0001] This utility model relates to a conveying device, and more particularly to a conveying transfer mechanism. Background Technology

[0002] In the industrial production of creams and lotions, to ensure uniform texture, extend shelf life, and meet subsequent filling or demolding requirements, the emulsified semi-fluid material needs to be rapidly cooled and solidified. Freezing tunnels are currently the mainstream equipment. They utilize a cryogenic unit in conjunction with a continuous conveying system (such as stainless steel mesh belts or cosmetic-grade conveyor belts) to allow the material to undergo a phase change from semi-fluid to semi-solid as it moves along the conveyor belt, forming a pre-formed product with a fixed shape. To adapt to workshop layouts or multi-process connections, the conveyor devices in freezing tunnels often need to have turning points. There are two main types: roller-turning type (where an active turning roller drives the conveyor belt to change direction) and arc-track type (where the conveyor belt slides along an arc-shaped track, with side guide wheels limiting deviation). The core principle is to ensure stable conveying at low temperatures and prevent material spillage or jamming.

[0003] However, in actual operation, the conveying at the turning point is not smooth enough, and the cosmetics are prone to vibration. This is mainly because the thrust experienced by the cosmetics during conveying changes direction suddenly after moving to the turning section, causing the cosmetics to shake. Cosmetics, being in a semi-fluid state, have very weak ability to buffer external vibrations. Even slight vibrations can affect the surface morphology. Therefore, vibration at the turning point will cause continuous ripples on the material surface, resulting in an uneven surface after cooling. Furthermore, the uneven distribution of ripples can easily lead to poor product consistency and failure to meet cosmetic surface quality standards. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a conveying and transfer mechanism that can make cosmetics turn smoothly and steadily at turning points during the conveying process without generating ripples.

[0005] To solve the above technical problems, the following technical solution is adopted:

[0006] A conveying and transfer mechanism is characterized in that it includes an arc-shaped transfer structure disposed between the end of a forward linear conveying section and the beginning of a reverse linear conveying section. The arc-shaped transfer structure is a passive transfer structure. The forward linear conveying section and the reverse linear conveying section are arranged side by side and close to each other. The apex of the arc-shaped transfer structure is located in the gap between the forward linear conveying section and the reverse linear conveying section.

[0007] In use, the aforementioned conveying transfer mechanism allows the conveying device to be configured in a meandering structure within the freezing tunnel, ensuring close contact between the sides of adjacent forward and reverse straight conveying sections. When setting up the conveying transfer mechanism, the arc-shaped transfer structure is positioned between the end of the forward straight conveying section and the beginning of the reverse straight conveying section, serving as a turning point for the conveying device. When conveying cosmetics, the cosmetics are first conveyed along the forward straight conveying section. Upon reaching the end, the cosmetics come into contact with the arc-shaped transfer structure. As the forward straight conveying section continues to apply forward force to the cosmetics, they move along the arc-shaped transfer structure, transferring from the end of the forward straight conveying section to the beginning of the reverse straight conveying section, and then being conveyed again by the reverse straight conveying section, in a continuous cycle. This conveyor transfer mechanism allows cosmetics to automatically change direction at turns by relying solely on the force applied by the forward linear conveyor section, greatly reducing interference from lateral forces and ensuring stable reversal. Furthermore, the linear conveyor sections in the freezing tunnel can be arranged close together, effectively saving space. At the same time, the conveyor transfer mechanism does not need to be integrated with the linear conveyor section and can be set at any position on the linear conveyor section as needed, thereby shortening or extending the conveying distance of cosmetics and adjusting the corresponding cooling time according to the needs of different cosmetics.

[0008] In a preferred embodiment, the arc-shaped transition structure includes a support and multiple rotating friction components. The support has an arc-shaped groove, and each rotating friction component is rotatably mounted on the sidewall of the arc-shaped groove. These rotating friction components are arranged sequentially along the length of the arc-shaped groove, with their sidewalls exposed above the groove. During installation, the arc-shaped transition structure is placed directly on the linear conveyor section, with the arc-shaped groove on the support spanning both the forward and reverse linear conveyor sections. The apex of the arc-shaped groove is located in the gap between the forward and reverse linear conveyor sections. When the cosmetic product is conveyed to the end of the forward linear conveyor section, it comes into contact with the rotating friction components on the arc-shaped groove. As the forward linear conveyor section continuously applies a forward force from below the cosmetic product, the cosmetic product moves along the contour of the arc-shaped groove via the rotating friction components, thus transferring from the end of the forward linear conveyor section to the beginning of the reverse linear conveyor section; then it continues to be conveyed by the reverse linear conveyor section, and so on in a cycle. Typically, the width of the arc-shaped groove is the same as the sum of the widths of the two adjacent linear conveyor sections.

[0009] In a further preferred embodiment, the arc-shaped groove is semi-circular. Since the two ends of the arc-shaped groove correspond to the outer edges of the two straight conveying sections, the use of a semi-circular arc-shaped groove allows the cosmetics to move more smoothly laterally along the contour of the arc-shaped groove when turning, further avoiding vibration.

[0010] In a further preferred embodiment, the rotating friction component includes a mounting shaft and multiple wear-resistant balls. The mounting shaft is installed in an arc-shaped groove, and each wear-resistant ball is rotatably fitted onto the mounting shaft from top to bottom, with the wheel surface of each wear-resistant ball exposed above the arc-shaped groove. For cosmetics with varying heights and uneven side shapes, compared to using a single long roller, the wear-resistant balls do not have an insufficient contact area, preventing them from overcoming resistance and rotating. The arrangement of multiple wear-resistant balls from top to bottom ensures that the cosmetic can contact any of the wear-resistant balls and move along the arc-shaped groove under the action of the wear-resistant balls. Typically, the wear-resistant balls are made of POM.

[0011] In a further preferred embodiment, the wear-resistant ball is shaped like a drum with a larger diameter in the middle than at both ends. This structure reduces the friction between adjacent wear-resistant balls, making their rotation smoother and thus facilitating the transfer of cosmetics.

[0012] In a further preferred embodiment, the number of wear-resistant balls is three.

[0013] In a further preferred embodiment, the bracket includes an upper wall panel, a lower wall panel, a rear wall panel, a left wall panel, and a right wall panel. The rear, left, and right edges of the upper wall panel are connected to the upper edges of the rear, left, and right wall panels, respectively. The rear, left, and right edges of the lower wall panel are connected to the lower edges of the rear, left, and right wall panels, respectively. The arc-shaped groove is formed on the front side of the upper and lower wall panels. Each of the rotating friction components is rotatably mounted between the upper and lower wall panels, and the sidewalls of the rotating friction components protrude from the front edges of the upper and lower wall panels. The bracket is composed of multiple wall panels, with the rotating friction components sandwiched between the upper and lower wall panels. It has a simple structure, is easy to assemble, is lightweight, and can be placed arbitrarily.

[0014] In a further preferred embodiment, the left and right rear corners of both the upper and lower wall panels are 90°. With this structure, the support can be placed at the corner of the freezing tunnel.

[0015] The beneficial effects of this utility model are as follows: this conveying and transfer mechanism can make cosmetics turn smoothly and steadily at turning points during the conveyor belt transportation, improve product stability, and prevent fluctuations during the conveyor belt transportation process.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0020] like Figure 1-3 The conveying and transfer mechanism shown includes an arc-shaped transfer structure 3 disposed between the end of the forward linear conveying section 1 and the beginning of the reverse linear conveying section 2. The arc-shaped transfer structure 3 is a passive transfer structure. The forward linear conveying section 1 and the reverse linear conveying section 2 are arranged side by side and close to each other. The arc-shaped transfer structure 3 includes a bracket 301 and a plurality of rotating friction elements 302. An arc-shaped groove 3011 is formed on the bracket 301. The apex of the arc-shaped groove 3011 is located in the gap between the forward linear conveying section 1 and the reverse linear conveying section 2. The sum of the widths of the forward linear conveying section 1 and the reverse linear conveying section 2 is the same as the width of the arc-shaped groove 3011. Each rotating friction element 302 is rotatably mounted on the side wall of the arc-shaped groove 3011, and each rotating friction element 302 is arranged sequentially along the length direction of the arc-shaped groove 3011. The side walls of the rotating friction elements 302 are exposed outside the arc-shaped groove 3011.

[0021] When the above-mentioned conveying and transfer mechanism is used, the conveying device can be set up in a meandering structure in the freezing tunnel, and the sides of the adjacent forward linear conveying section 1 and reverse linear conveying section 2 are in close contact. During setup, the arc-shaped transfer structure 3 is placed directly on the linear conveying section, and the arc-shaped groove 3011 on the bracket 301 spans over the forward linear conveying section 1 and the reverse linear conveying section 2. The arc-shaped transfer structure 3 can serve as the turning section of the conveying device. When conveying cosmetics, the cosmetics are first conveyed along the forward linear conveying section 1. When conveyed to the end, the cosmetics come into contact with the rotating friction element 302 located on the arc-shaped groove 3011. As the forward linear conveying section 1 continuously applies a forward force to the cosmetics, the cosmetics can move along the contour of the arc-shaped groove 3011 through the rotating friction element 302, thereby transferring from the end of the forward linear conveying section 1 to the beginning of the reverse linear conveying section 2, and then being conveyed by the reverse linear conveying section 2, in a cyclical manner. This conveying and transfer mechanism enables cosmetics to automatically change direction along the arc-shaped transfer structure 3 at turns, relying solely on the force applied by the forward linear conveying section 1. This greatly reduces interference from lateral forces when the cosmetics turn, ensuring a stable change in direction. Furthermore, the linear conveying sections in the freezing tunnel can be arranged close together, effectively saving space. At the same time, the conveying and transfer mechanism does not need to be integrated with the linear conveying section and can be set at any position on the linear conveying section as needed, thereby shortening or extending the conveying distance of the cosmetics and adjusting the corresponding cooling time according to the needs of different cosmetics.

[0022] The arc-shaped groove 3011 is semi-circular. Since the two ends of the arc-shaped groove 3011 correspond to the outer edges of the two straight conveying sections, the use of a semi-circular arc-shaped groove 3011 allows the cosmetics to move more stably along the contour of the arc-shaped groove 3011 when turning, without getting stuck.

[0023] The rotating friction element 302 includes a mounting shaft 3021 and three wear-resistant balls 3022. The mounting shaft 3021 is installed in an arc-shaped groove 3011. Each wear-resistant ball 3022 is rotatably mounted on the mounting shaft 3021 from top to bottom, with the wheel surface of each wear-resistant ball 3022 exposed in the arc-shaped groove 3011. For cosmetics with varying heights and uneven side shapes, compared to using a single long roller, the contact area of ​​the wear-resistant balls 3022 is not too small, preventing them from overcoming resistance and rotating. The arrangement of multiple wear-resistant balls 3022 from top to bottom ensures that the cosmetic can contact any of the wear-resistant balls 3022 and move along the arc-shaped groove 3011 under the action of the wear-resistant balls 3022. The wear-resistant balls 3022 are made of POM.

[0024] The wear-resistant ball bearing 3022 has a waist-shaped design with a larger diameter in the middle than at both ends. This structure reduces the friction between adjacent wear-resistant balls 3022, making their rotation smoother and thus facilitating the transfer of cosmetics.

[0025] The bracket 301 includes an upper wall plate 3012, a lower wall plate 3013, a rear wall plate (not visible in the figure), a left wall plate (not visible in the figure), and a right wall plate 3014. The rear edge, left edge, and right edge of the upper wall plate 3012 are connected to the upper edge of the rear wall plate, left wall plate, and right wall plate 3014, respectively. The rear edge, left edge, and right edge of the lower wall plate 3013 are connected to the lower edge of the rear wall plate, left wall plate, and right wall plate 3014, respectively. The left rear corner and right rear corner of the upper wall plate 3012 and the lower wall plate 3013 are both 90°. An arc-shaped groove 3011 is formed on the front side of the upper wall plate 3012 and the lower wall plate 3013. Each rotating friction element 302 is rotatably installed between the upper wall plate 3012 and the lower wall plate 3013, and the sidewall of the rotating friction element 302 is exposed at the front edge of the upper wall plate 3012 and the lower wall plate 3013. The bracket 301 is composed of multiple wall panels, and the rotating friction component 302 is sandwiched between the upper wall panel 3012 and the lower wall panel 3013. It has a simple structure, is easy to assemble, is lightweight, can be placed at will, and can be placed in the corner of the freezing tunnel.
