Description

Technical Field

[0001] This application relates to the technical field of latex glove production equipment, and in particular to a hand mold conveyor chain positioning device. Background Technology

[0002] As a core piece of hand protection equipment, the technological development of latex gloves has always been deeply intertwined with the needs of the medical, industrial, and consumer sectors. Latex gloves are manufactured through processes such as impregnation with a hand mold, vulcanization, and demolding. They possess high elasticity, a snug fit, and tear resistance, and are widely used in surgical, precision manufacturing, and everyday protective applications.

[0003] The patent document with the existing authorized public account number CN219276736U discloses a high-efficiency dual-mold natural latex glove production line. In this solution, the main frame is divided into upper and lower layers, and the hand mold is circulated through the main chain to complete the processes of cleaning, impregnation, drying, and demolding in sequence.

[0004] In this design, the main chain is mounted on a main track tray. The main chain moves along the tray, driving the hand mold to perform processes such as dip coating. However, in some production lines, the main track tray has an inclined section, particularly around the dip coating tank, where the incline makes it easier for the hand mold to be immersed. This inclined section weakens the support of the main track tray for the main chain, making it more prone to swaying and shifting. Utility Model Content

[0005] To better position the chain, this application provides a hand mold conveyor chain positioning device.

[0006] The technical solution adopted in this application is as follows:

[0007] A hand mold conveyor chain positioning device includes a mounting base, a connecting base, an adjusting component, and an abutment plate; the adjusting component is connected between the mounting base and the connecting base and is used to adjust the distance between the mounting base and the connecting base; the abutment plate is disposed on the side of the connecting base away from the mounting base; the connecting base is provided with a backstop, which is used to position the adjusting component to prevent the connection between the adjusting component and the connecting base from becoming loose.

[0008] By adopting the above technical solution, the connecting seat is connected to the mounting seat by adjusting the component, and the abutment plate can abut against the chain, thereby limiting the chain position; by adjusting the distance between the connecting seat and the mounting seat, the position of the abutment plate can be adjusted to better adapt to the position of the chain.

[0009] Optionally, the adjustment assembly includes a fixing rod fixed to the mounting base and two locking blocks threaded to the fixing rod. The fixing rod slides through the connecting base, and the two locking blocks abut against the upper and lower sides of the connecting base respectively. The anti-reverse component is used to position the locking blocks to prevent them from rotating in the opposite direction after they abut against the connecting base.

[0010] By adopting the above technical solution, the locking block is pressed against the upper and lower sides of the connecting seat, thereby positioning the connecting seat and preventing it from moving up and down.

[0011] Optionally, the end of the connecting seat is provided with a mounting groove, and the anti-reverse component includes a sliding post slidably installed in the mounting groove, an elastic element disposed in the mounting groove, and an abutment portion disposed on the side wall of the sliding post; two abutment portions are provided, and each abutment portion includes an extension rod extending in the radial direction of the sliding post and an anti-reverse rod disposed at the end of the extension rod away from the sliding post; the side wall of the locking block is provided with an abutment groove, and multiple abutment grooves are evenly arranged along the circumference of the locking block, and the elastic element can drive the anti-reverse rod to be inserted into the abutment groove.

[0012] By adopting the above technical solution, the anti-reverse rod abuts against the contact groove, thereby restricting the rotation of the locking block, so that the locking block cannot loosen and the connection of the connecting seat is maintained.

[0013] Optionally, the locking block includes an abutting block that abuts against the surface of the connecting seat and a prism block fixed to the side of the abutting block away from the connecting seat, and the abutting groove is provided on the side wall of the abutting block.

Detailed Implementation

[0032] The present application will be further described in detail below with reference to the accompanying drawings.

[0033] This application discloses a positioning device for a hand mold conveyor chain. (Refer to...) Figure 1 and Figure 2 The latex hand mold is mounted on the chain and enters the impregnation tank for impregnation as the chain moves. This is existing technology and will not be elaborated upon here. The positioning device is used to position the chain to improve its stability.

[0034] The positioning device includes a mounting base 1, a connecting base 2, an adjusting component 3, and an abutment plate 14. The mounting base 1 is installed on the production line frame by bolts or welding. The connecting base 2 is connected to the mounting base 1 via the adjusting component 3, and the distance between the connecting base 2 and the mounting base 1 can be adjusted by the adjusting component 3. The abutment plate 14 is installed below the connecting base 2 and above the chain. By adjusting the position of the connecting base 2, the abutment plate 14 abuts against the chain surface, thereby positioning the chain. The positioning device is located at the corresponding position of the impregnation tank. In this embodiment, the chain's movement trajectory first slopes downwards, then slopes upwards after passing through the impregnation tank. The two ends of the abutment plate 14 form an arc-shaped structure, positioning the chain and making the chain movement more stable. The positioning device can also be spaced along the chain's movement direction, or it can be positioned when the chain is horizontal to enhance chain stability.

[0035] Reference Figure 2 and Figure 3 The adjusting assembly 3 includes a fixing rod 31 fixed to the mounting base 1 and two locking blocks 32 threadedly connected to the side wall of the fixing rod 31. Two fixing rods 31 are fixed to the mounting base 1, and the fixing rods 31 slide through both ends of the connecting seat 2. The two locking blocks 32 on each fixing rod 31 are located on the upper and lower sides of the connecting seat 2, respectively, and the locking blocks 32 abut against the surface of the connecting seat 2, thereby positioning the connecting seat 2. When the vertical height of the connecting seat 2 needs to be adjusted, the position of the locking blocks 32 is adjusted.

[0036] A hollow layer 12 is fixed to the upper end of the abutment plate 14. The hollow layer 12 enhances the overall mechanical strength of the abutment plate 14 without excessively increasing its weight. Furthermore, two connecting seats 2 are fixed to the abutment plate 14, with the mounting seat 1 and connecting seat 2 corresponding one-to-one. The two connecting seats 2 further improve the overall stability of the abutment plate 14. Additionally, a reinforcing rod 13 is fixed between the upper surface of the abutment plate 14 and the connecting seats 2, further enhancing the overall structural stability.

[0037] Reference Figure 2 and Figure 3The abutment plate 14 abuts against the chain. During long-term use, the locking block 32 may loosen, which may cause the connecting seat 2 to wobble. Therefore, a backstop 4 is installed on the connecting seat 2. The backstop 4 is used to position the locking block 32, making it less likely for the locking block 32 to loosen.

[0038] The connecting seat 2 has mounting grooves 5 on both end faces. The anti-reverse component 4 includes a sliding post 41 slidably inserted into the mounting groove 5, an elastic element 42 installed in the mounting groove 5, and an abutment part 43 installed on the end of the sliding post 41 extending beyond the mounting groove 5. The sliding post 41 has a quadrangular prism structure. The elastic element 42 is a spring or tension spring, with one end connected to the end face of the sliding post 41 and the other end connected to the inner end face of the mounting groove 5. There are two abutment parts 43, located on the upper and lower sides of the sliding post 41, respectively. The abutment part 43 includes an extension rod 431 fixed to the side wall of the sliding post, and an anti-reverse rod 432 fixed to the end of the extension rod 431 away from the sliding post 41. The anti-reverse rod 432 extends towards the locking block 32, and its end is a pointed structure. The side wall of the locking block 32 has an abutment groove 6, and multiple abutment grooves 6 are evenly arranged along the circumferential direction of the locking block 32. The locking block 32 has a toothed structure on its sidewall, forming an abutment groove 6. The elastic element 42 is in a stretched state. Under the action of the elastic element 42, one end of the anti-reverse rod 432 abuts against the abutment groove 6, thereby restricting the rotation of the locking block 32. The anti-reverse rod 432 and the locking block 32 correspond one-to-one, thus preventing the locking block 32 from rotating backwards.

[0039] The locking block 32 has a circular abutment block 321 and a prism block 322 fixed on the abutment block 321. The prism block 322 is preferably a hexagonal prism structure, and the prism is located on the side of the abutment block 321 away from the connecting seat 2, so as to facilitate the rotation of the locking block 32 with a tool. The abutment groove 6 is formed in the side wall of the abutment block 321.

[0040] Furthermore, refer to Figure 3 and Figure 4 A limiting member 7 is installed on the side wall of the sliding column 41. When the anti-reverse rod 432 abuts in the contact groove 6, the limiting member 7 can limit the sliding column 41 so that the sliding column 41 cannot slide in the mounting groove 5.

[0041] The side wall of the connecting seat 2 has a limiting hole 8, which is connected to the mounting groove 5. The side wall of the sliding column 41 has a receiving groove 9. The limiting member 7 includes a limiting column 71 that is slidably inserted into the receiving groove 9 and a reset member 72 installed in the receiving groove 9. The reset member 72 is a spring, with one end connected to the end face of the limiting column 71 and the other end connected to the inner end face of the receiving groove 9. When the anti-reverse rod 432 abuts against the contact groove 6, the limiting column 71 corresponds to the position of the limiting hole 8, and the reset member 72 drives the limiting column 71 to pass through the limiting hole 8. One end of the limiting column 71 has an arc-shaped structure, which makes it easier for the limiting column 71 to pass through the limiting hole 8.

[0042] When the locking block 32 needs to be operated, manually squeeze the limiting post 71 so that it retracts into the receiving groove 9. Then slide the sliding post 41 out of the mounting groove 5. When the limiting post 71 disengages from the inner wall of the receiving groove 9, the limiting post 71 pops out. At this time, under the action of the elastic element 42, the side wall of the limiting post 71 abuts against the end face of the connecting seat 2, thereby separating the anti-reverse rod 432 from the locking block 32. The limiting post 71 is pushed back into the receiving groove 9, and the elastic element 42 can then drive the anti-reverse rod 432 to abut against the contact groove 6 again.

[0043] The implementation principle of the hand mold conveyor chain positioning device in this application embodiment is as follows: by adjusting the position of the connecting seat 2, the abutment plate 14 abuts against the chain, thereby limiting the chain. In particular, for the positions of the chain with uphill and downhill sections in the production line, the chain is more stable under the positioning of the positioning device.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
