[0001] The invention relates to the technical field of production of dipped gloves, in particular to an automatic demoulding mechanism for a production line of dipped gloves. Background Art

[0002] Dipped gloves, as a common type of protective gloves, are mainly made by soaking glove materials (such as cloth or leather) in rubber or other synthetic glue liquid and undergoing a series of process treatments. After the dipping is completed, the dipped gloves need to be removed from the mold. When the gloves are demolded, they are usually pulled off from the fingers by an external device. The gloves tightly fitted on the mold are subjected to the pulling force while also being subjected to the friction between the mold, which increases the risk of deformation and damage to the gloves, thereby reducing the production quality of the dipped gloves.

[0003] Combining the above problems, we will find that it is difficult to avoid the above problems at the same time when using the existing demoulding devices for dipped gloves on the market, and even if they can be solved, they need to be solved with the cooperation of external tools, thus failing to achieve the desired effect.

[0023] A sliding hole 2116 is provided at the top of the support rod 1, and the pressure rod 2115 is slidably connected to the inner cavity of the sliding hole 2116. By providing the sliding hole 2116, the vertical movement of the pressure rod 2115 is guided, thereby ensuring the stability of the pressure rod 2115 during vertical movement.

[0024] The bottom of the first palm mold 2101 is fixedly connected to a limiting sleeve 2117, and the bottom of the second palm mold 2102 is fixedly connected to a limiting sleeve rod 2118. The limiting sleeve rod 2118 is slidably connected to the inner wall of the limiting sleeve 2117. The inner wall of the limiting sleeve 2117 is fixedly connected with a first tension spring 2119. The other end of the first tension spring 2119 is fixedly connected to one end of the limiting sleeve rod 2118. There are two first tension springs 2119.

Through the third tension spring 2126, the elastic adjustment of the moving distance of the second palm mold 2102 is achieved, and the elastic coefficient of the third tension spring 2126 is smaller than the lateral driving force generated when the inclined block 2104 moves downward.

[0027] The specific implementation of this embodiment is as follows: when performing the glove dipping process, the user puts the produced gloves on the mold surface in advance. 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, then the size of the normal mold will be formed, that is, the size of the gloves fully supported. The user starts the hydraulic rod 2113 on 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 shrink, driving the pressing plate 2114 to approach the support rod 1. In the process of approaching, the pressing plate 2114 will gradually contact with the pressing rod 2115, forming a downward squeeze on the pressing rod 2115. When the pressing rod 2115 is pressed down, the cooperation between the limiting disc 2118 and the sliding hole 2116 , compressing the first spring 2117, the downward movement of the pressure rod 2115 drives the inclined block 2104 to move downward, and in the process of moving downward, the inclined block 2104 cooperates with the inclined groove 2103 to push the second palm mold 2102 horizontally, so that a distance is generated between the first palm mold 2101 and the second palm mold 2102, and the downward movement of the inclined block 2104 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, so that the air in the piston cylinder 2106 enters the inner cavity of the five air bags 2112 through the five air pipes 2111, respectively, so that the air bags 2112 expand, and when the air bags 2112 expand, they form a support between the first half mold 2109 and the second half mold 2110, so that the first half mold 21 09 creates a distance between the second half mold 2110, so that the finger mold 2108 forms the size of the normal mold finger. During the downward movement of the inclined block 2104, the related structure of the linkage pushing unit 22 is tightly fitted with the bottom of the finger mold 2108. After the mold size adjustment is completed, the entire hand-shaped device is collectively referred to as a mold. The user puts the prepared gloves on the surface of the mold, and together with the support rod 1, performs the dipping process through the conveying equipment of the production line. Subsequently, the gloves that have been dipped in glue need to be demolded. The telescopic end of the hydraulic rod 2113 is extended by the power supply of the production line to control the extension of the telescopic end of the hydraulic rod 2113. 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 squeezing force on the pressure rod 2115. At this time, the first spring 211 7 drives the pressure rod 2115 to move upward, and 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 guide column 2125, the second palm mold 2102 is gradually reset smoothly, that is, the second palm molds 2102 are gradually approached to each other. As the piston block 2107 moves upward, a negative pressure area is formed in the inner cavity of the piston cylinder 2106, so that the gas in the airbag 2112 enters the inner cavity of the piston cylinder 2106 through the trachea 2111.The airbag 2112 that has lost its air loses its support for the first half mold 2109 and the second half mold 2110. At this time, the distance between the first half mold 2109 and the second half mold 2110 is reduced through the guidance of the sliding groove 2120 and the insertion rod 2121 and the reaction force of the second tension spring 2122. When the pressure rod 2115 moves up to the maximum displacement, the first palm mold 2101 and the second palm mold 2102 are completely fitted, and the first half mold 2109 and the second half mold 2110 are completely fitted. At this time, the inner cavity of the glove loses the full support of the mold, so that the glove is in a relaxed state, ensuring that the friction between the glove and the mold is minimized when the glove is demolded.

[0028] Example 2: Please refer to Figure 10-12 The present invention provides a technical solution: an automatic demoulding mechanism for a dipped 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, which is arranged inside the opening and closing unit 21. The pushing unit 22 is used in conjunction with the opening and closing unit 21. The pushing unit 22 is used to assist the dipped glove lower mold.

[0029] As a further limitation of the lower mold mechanism 2 of the present invention, the pushing unit 22 includes two vertical displacement grooves 2201 opened on the opposite sides of the first palm mold 2101 and the second palm mold 2102, and the bottoms of the first palm mold 2101 and the second palm mold 2102 are both provided with through holes 2202, and the through holes 2202 are connected to the vertical displacement grooves 2201, and the vertical displacement grooves 2201 and the inner cavities of the through holes 2202 are slidably connected with L-shaped rods 2203, and the number of L-shaped rods 2203 is two, and the bottom of the L-shaped rods 2203 is fixedly connected with tooth plates 2204, and the number of tooth plates 2204 is two, and the two sides of the piston cylinder 2106 are rotatably connected with connecting rods 2205 through bearings, and one end of the connecting rod 2205 is fixedly connected with a gear 2206, and the gear 2206 is meshed with the tooth plate 2204, and the surfaces of the two connecting rods 2205 are fixedly connected together. There are five steel wires 2207, which correspond to five finger molds 2108 respectively. The inner wall of the first half mold 2109 is slidably connected with a push rod 2208, and the top of the push rod 2208 is fixedly connected with a fourth tension spring 2209, and 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 wires 2207 respectively penetrate the first palm mold 2101 and the second palm mold 2102 and are fixedly connected to the top of the push rod 2208. The bottom of the push rod 2208 is fixedly connected with a push block 2210, and 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 demoulded, the upward moving force of the opening and closing unit 21 is converted into the downward thrust of the push block 2210, and the glove is pushed downward from the inside of the glove finger, thereby accelerating the separation between the glove and the mold.

[0030] The surface of the connecting rod 2205 is fixedly connected with a baffle 2211, and the number of the baffles 2211 is several; by setting the baffles 2211, the five steel wire ropes 2207 are spaced apart, ensuring the separate intervals when the five steel wire ropes 2207 are unwound and reeled.

[0031] A transverse plate 2212 is fixedly connected to one side of the piston cylinder 2106, and three guide plates 2213 are fixedly connected to the top of the transverse plate 2212. The wire rope 2207 is slidably connected to the inner wall of the guide plate 2213. By setting the transverse plate 2212 and the guide plate 2213, the guidance of the five steel wire ropes 2207 is achieved, ensuring the smooth winding and unwinding of the steel wire ropes 2207.

[0032] The specific implementation of this embodiment is as follows: when the glove is demoulded, the inclined block 2104 drives the L-shaped rod 2203 to move upward during the upward movement, and the upward movement of the L-shaped rod 2203 drives the tooth plate 2204 to move upward. The upward movement of the tooth plate 2204 causes the gear 2206 to rotate, and the rotation of the gear 2206 drives the connecting rod 2205 to rotate. The connecting rod 2205 unwinds the steel wire rope 2207 when rotating. After modeling, the steel wire rope 2207 is in a reeled state, and the fourth tension spring 2209 is in a state of being wound. In the compressed state, the push rod 2208 is also completely received into the inner wall of the first half mold 2109 by the tension of the steel wire rope 2207. When the steel wire rope 2207 begins to unwind and become loose, the reaction force of the fourth tension spring 2209 pushes the push rod 2208 which has lost the 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 fingertips of the glove, driving the loosened glove on the surface of the mold to move downward, so that the glove gradually leaves the mold, thereby realizing the demolding of the glove.

[0033] Example 3: Please refer to Fig.13 The present invention provides a technical solution: an automatic demoulding mechanism for a dipped glove production line. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. The lower mold mechanism 2 also includes an auxiliary pushing unit 23, which is arranged at the bottom of the support rod 1. The auxiliary pushing unit 23 is used in conjunction with the opening and closing unit 21 and the pushing unit 22. The auxiliary pushing unit 23 is used to cooperate with the pushing unit 22 to demould the dipped gloves.

[0034] As a further limitation of the lower mold mechanism 2 of the present invention, the auxiliary push unit 23 includes two multi-section electric push rods 2301 fixedly connected to the inner wall of the support rod 1, and the two multi-section electric push rods 2301 are respectively arranged on one side of the first palm mold 2101 and the second palm mold 2102, and the telescopic ends of the two multi-section electric push rods 2301 are fixedly connected with positioning blocks 2302, and the opposite sides of the two positioning blocks 2302 are fixedly connected with push plates 2303, and the two push plates 2303 are respectively arranged on the front and rear sides of the first palm mold 2101 and the second palm mold 2102; by setting the auxiliary push unit 23, auxiliary pushing of the gloves during demolding can be achieved, the gloves can be completely demolded, and the efficiency of glove demolding is improved.
