Description

Technical Field

[0001] The present invention relates to the technical field of dipped glove production, and particularly to an automatic demoulding mechanism for a dipped glove production line. Background Art

[0002] Dipped gloves, as a common type of protective gloves, are mainly made by soaking glove materials (such as fabrics or leathers) in rubber or other synthetic rubber solutions and going through a series of technological processes. After dipping, the dipped gloves need to be removed from the molds. When demoulding the gloves, usually an external device is used to pull off the gloves tightly sleeved on the molds from the finger parts. The gloves tightly sleeved on the molds bear the pulling force and at the same time the frictional force with the molds, increasing the risk of causing glove deformation and damage, thereby reducing the production quality of the dipped gloves.

[0003] Combining the above problems, we will find that the existing demoulding devices for dipped gloves on the market are very difficult to avoid the above-mentioned problems simultaneously when in use, and even if they can be solved, they need to be solved by cooperating with external tools, thus unable to achieve the desired effect.

An inclined block 2104 is slidably connected to the inner cavities of the two oblique grooves 2103. An extension rod 2105 is fixedly connected to the bottom of the inclined block 2104. A piston cylinder 2106 is fixedly connected to the bottom of the first palm mold 2101. The bottom of the extension rod 2105 penetrates into the inner cavity of the piston cylinder 2106 and is fixedly connected to a piston block 2107. The piston block 2107 is slidably connected to the inner cavity of the piston cylinder 2106. Finger molds 2108 are arranged on the surfaces of the first palm mold 2101 and the second palm mold 2102. The total number of finger molds 2108 is five. The finger mold 2108 includes a first half mold 2109 and a second half mold 2110. The five first half molds 2109 are respectively fixedly connected to the first palm mold 2101 and the second palm mold 2102. The second half mold 2110 is slidably connected to the first half mold 2109. Five air pipes 2111 are fixedly communicated with the bottom of the piston cylinder 2106. Air bags 2112 are clamped in the inner cavities of the five finger molds 2108. One ends of the air pipes 2111 penetrate through the first half molds 2109 and are fixedly communicated with the air bags 2112. A hydraulic rod 2113 is fixedly connected to the inner wall of the support rod 1. A pressing plate 2114 is fixedly connected to the telescopic end of the hydraulic rod 2113. A pressing rod 2115 is fixedly connected to the top of the inclined block 2104. The pressing rod 2115 is slidably connected to the inner wall of the support rod 1. The bottom of the pressing plate 2114 is fixedly connected to the top of the pressing rod 2115; by setting the clamping unit 21, the distance between the first palm mold 2101 and the second palm mold 2102 can be adjusted, so that after dipping glue, it is convenient to reduce the distance between the first palm mold 2101 and the second palm mold 2102, cancel the full support for the inside of the glove, and make the glove relax on the surface of the mold, thereby reducing the friction between the glove and the mold during demolding and reducing the risk of glove deformation damage.

[0040] A sliding hole 2116 is formed at the top of the support rod 1. The pressing rod 2115 is slidably connected to the inner cavity of the sliding hole 2116. By setting the sliding hole 2116, the vertical movement of the pressing rod 2115 is guided, ensuring the stability of the pressing rod 2115 during vertical movement.

[0041] A limiting sleeve 2117 is fixedly connected to the bottom of the first palm mold 2101, and a limiting sleeve rod 2118 is fixedly connected to the bottom of the second palm mold 2102. The limiting sleeve rod 2118 is slidably connected to the inner wall of the limiting sleeve 2117. A first tension spring 2119 is fixedly connected to the inner wall of the limiting sleeve 2117, and the other end of the first tension spring 2119 is fixedly connected to one end of the limiting sleeve rod 2118. The number of the first tension springs 2119 is two. By providing the limiting sleeve 2117, the limiting sleeve rod 2118 and the first tension spring 2119, an elastic connection between the first palm mold 2101 and the second palm mold 2102 is achieved, and an elastic adjustment of the distance between the first palm mold 2101 and the second palm mold 2102 is realized. The elastic coefficient of the first tension spring 2119 is smaller than the lateral driving force generated when the inclined block 2104 moves downward.

[0042] Four sliding grooves 2120 are formed in one side of the first half mold 2109, and four inserting rods 2121 are fixedly connected to one side of the second half mold 2110. The inserting rods 2121 are slidably connected to the inner cavity of the sliding grooves 2120. A second tension spring 2122 is fixedly connected to one end of the inserting rods 2121, and one end of the second tension spring 2122 is fixedly connected to the inner wall of the sliding grooves 2120. By providing the sliding grooves 2120, the inserting rods 2121 and the second tension spring 2122, an elastic connection between the first half mold 2109 and the second half mold 2110 is achieved, and an elastic adjustment of the distance between the first half mold 2109 and the second half mold 2110 is completed. The elastic coefficient of the second tension spring 2122 is smaller than the expansion force of the airbag.

[0043] A moving groove 2123 is formed in the bottom of the support rod 1, and a moving block 2124 is fixedly connected to the top of the second palm mold 2102. The moving block 2124 is slidably connected to the inner wall of the moving groove 2123. A guiding column 2125 is fixedly connected to the inner wall of the moving groove 2123. The moving block 2124 is slidably connected to the surface of the guiding column 2125. A third tension spring 2126 is fixedly connected to one side of the moving block 2124. The third tension spring 2126 is slidably sleeved on the surface of the guiding column 2125, and one end of the third tension spring 2126 is fixedly connected to the inside of the moving groove 2123. By providing the moving groove 2123, the moving block 2124 and the guiding column 2125, the guiding of the lateral movement track of the second palm mold 2102 at the bottom of the support rod 1 can be realized, ensuring the stability of the second palm mold 2102 during movement. Through the third tension spring 2126, an elastic adjustment of the moving distance of the second palm mold 2102 is realized. The elastic coefficient of the third tension spring 2126 is smaller than the lateral driving force generated when the inclined block 2104 moves downward.

[0044] The specific implementation method of this embodiment is as follows: When performing the glove dipping process, the user first puts the produced gloves on the surface of the mold. Before putting on the gloves, it is necessary to adjust the distance between the first palm mold 2101 and the second palm mold 2102 to the maximum, at which time the size of the normal mold is formed, that is, the size for the gloves to be fully supported. The user starts the hydraulic rod 2113 at the top of the support rod 1 through the power supply equipped in the dipping glove production line. The telescopic end of the hydraulic rod 2113 will contract, driving the pressure plate 2114 to approach the support rod 1. During the approaching process of the pressure plate 2114, it will gradually contact the pressure rod 2115 and form a downward extrusion on the pressure rod 2115. When the pressure rod 2115 is pressed down, the first spring is compressed through the cooperation of the limiting disc and the sliding hole 2116. The downward movement of the pressure rod 2115 drives the inclined block 2104 to move downward. During the downward movement of the inclined block 2104, it cooperates with the inclined groove 2103 to laterally push the second palm mold 2102, causing a distance to be generated between the first palm mold 2101 and the second palm mold 2102. As the inclined block 2104 moves downward, it drives the extension rod 2105 to move downward. When the extension rod 2105 moves downward, it drives the piston block 2107 to move downward in the inner cavity of the piston cylinder 2106, causing the air in the piston cylinder 2106 to enter the inner cavities of the five air bags 2112 through the five air pipes 2111 respectively, causing the air bags 2112 to expand. When the air bags 2112 expand, they form a support between the first half mold 2109 and the second half mold 2110, causing a distance to be generated between the first half mold 2109 and the second half mold 2110, thereby enabling the finger mold 2108 to form the size at the finger part of the normal mold. During the downward movement of the inclined block 2104, the relevant structures of the linkage pushing unit 22 are closely attached to the bottom of the finger mold 2108. After the mold size is adjusted, the entire hand-shaped device is collectively referred to as the mold. The user puts the prepared gloves on the surface of the mold and follows the support rod 1 to perform the dipping process through the conveying equipment of the production line. Subsequently, it is necessary to demold the dipped gloves. The power supply of the production line is used to control the telescopic end of the hydraulic rod 2113 to extend. The extension of the telescopic end of the hydraulic rod 2113 drives the pressure plate 2114 to move upward. The upward movement of the pressure plate 2114 cancels the extrusion force on the pressure rod 2115. At this time, the reaction force of the first spring drives the pressure rod 2115 to move upward. The upward movement of the pressure rod 2115 drives the inclined block 2104, the extension rod 2105, and the piston block 2107 to move upward. When the inclined block 2104 moves upward, it cooperates with the inclined groove 2103 to gradually reduce the lateral extrusion force on the second palm mold 2102. At this time, through the reaction force of the third tension spring 2126 and the guiding properties of the moving groove 2123, the moving block 2124, and the guiding column 2125, the second palm mold 2102 is gradually and smoothly reset, that is, the second palm mold 2102 gradually approaches the second palm mold 2102. As the piston block 2107 moves upward, a negative pressure area is formed in the inner cavity of the piston cylinder 2106, causing the gas in the air bags 2112 to enter the inner cavity of the piston cylinder 2106 through the air pipes 2111 respectively.The airbag 2112 that has lost air loses the support between the first half mold 2109 and the second half mold 2110. At this time, through the guiding of the sliding groove 2120 and the insertion rod 2121 and the reaction force of the second tension spring 2122, the distance between the first half mold 2109 and the second half mold 2110 is reduced. When the pressure rod 2115 moves upward to the maximum displacement, the first palm mold 2101 and the second palm mold 2102 are completely attached, and the first half mold 2109 and the second half mold 2110 are completely attached. At this time, the inner cavity of the glove loses the full support of the mold, making the glove in a relaxed state, ensuring that the friction between the glove and the mold is minimized during demolding.

[0045] Embodiment 2: Please refer to Figures 10 - 12 , the present invention provides a technical solution: an automatic demolding mechanism for a dipping glove production line. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. The lower mold mechanism 2 includes a pushing unit 22, the pushing unit 22 is arranged inside the opening and closing unit 21, the pushing unit 22 is used in cooperation with the opening and closing unit 21, and the pushing unit 22 is used to assist in demolding the dipping glove.

[0046] As a further limitation of the lower mold mechanism 2 of the present invention, the pushing unit 22 includes two vertical moving grooves 2201 opened on the opposite sides of the first palm mold 2101 and the second palm mold 2102. Through holes 2202 are opened at the bottoms of the first palm mold 2101 and the second palm mold 2102. The through holes 2202 are communicated with the vertical moving grooves 2201. The inner cavities of the vertical moving grooves 2201 and the through holes 2202 are jointly slidably connected with L-shaped rods 2203. The number of L-shaped rods 2203 is two. A toothed plate 2204 is fixedly connected to the bottom of the L-shaped rod 2203. The number of toothed plates 2204 is two. Connecting rods 2205 are rotatably connected to both sides of the piston cylinder 2106 through bearings. One end of the connecting rod 2205 is fixedly connected with a gear 2206. The gear 2206 meshes with the toothed plate 2204. Five steel wire ropes 2207 are fixedly connected to the surfaces of the two connecting rods 2205. The five steel wire ropes 2207 respectively correspond to the five finger molds 2108. A push rod 2208 is slidably connected to the inner wall of the first half mold 2109. A fourth tension spring 2209 is fixedly connected to the top of the push rod 2208. One end of the fourth tension spring 2209 is fixedly connected to the inner top wall of the first half mold 2109. The five steel wire ropes 2207 respectively penetrate through the first palm mold 2101 and the second palm mold 2102 and are fixedly connected to the top of the push rod 2208. A push block 2210 is fixedly connected to the bottom of the push rod 2208. The top of the push block 2210 contacts the bottom of the finger mold 2108; by setting the pushing unit 22, when the glove is demolded, the upward force of the opening and closing unit 21 is converted into the downward pushing force of the push block 2210, and it is pushed downward from the inside of the glove finger, accelerating the separation between the glove and the mold.

[0047] A baffle 2211 is fixedly connected to the surface of the connecting rod 2205, and the number of baffles 2211 is several; by providing the baffle 2211, the spacing of the five steel wire ropes 2207 is realized, ensuring a separate area for the unwinding and rewinding of the five steel wire ropes 2207.

[0048] One side of the piston cylinder 2106 is fixedly connected to a cross plate 2212, and three guide plates 2213 are fixedly connected to the top of the cross plate 2212. The steel wire rope 2207 is slidably connected to the inner wall of the guide plate 2213; by providing the cross plate 2212 and the guide plate 2213, the guiding of the five steel wire ropes 2207 is realized, ensuring the smooth unwinding and rewinding of the steel wire rope 2207.

[0049] The specific implementation manner of this embodiment is as follows: When demolding the glove, during the upward movement of the inclined block 2104, the L-shaped rod 2203 is driven to move upward. The upward movement of the L-shaped rod 2203 drives the toothed plate 2204 to move upward. The upward movement of the toothed plate 2204 causes the gear 2206 to rotate. The rotation of the gear 2206 drives the connecting rod 2205 to rotate. When the connecting rod 2205 rotates, the steel wire rope 2207 is unwound. After modeling, the steel wire rope 2207 is in a rewound state, the fourth tension spring 2209 is in a compressed state, and the push rod 2208 is also completely received into the inner wall of the first half mold 2109 due to the tension of the steel wire rope 2207. When the steel wire rope 2207 starts to unwind and becomes slack, the reaction force of the fourth tension spring 2209 pushes the push rod 2208 that has lost tension to move downward. The downward movement of the push rod 2208 drives the push block 2210 to move downward. At this time, the push block 2210 is in the inner cavity at the finger part of the glove, driving the glove that is slackly sleeved on the mold surface to move downward, gradually separating the glove from the mold, realizing the demolding of the glove.

[0050] Embodiment 3: Please refer to Figure 13 , the present invention provides a technical solution: An automatic demolding mechanism for a dipped glove production line. The present invention makes corresponding improvements to the technical problems mentioned in the background art. The lower mold mechanism 2 further includes an auxiliary pushing unit 23. The auxiliary pushing unit 23 is arranged at the bottom of the support rod 1. The auxiliary pushing unit 23 is used in cooperation with the opening and closing unit 21 and the pushing unit 22, and the auxiliary pushing unit 23 is used to cooperate with the pushing unit 22 to demold the dipped glove together.
