[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0022] like Figures 1-4 As shown, this utility model provides a technical solution: a paper cup body forming mold, including a base 1, a bracket 11 fixedly connected to the upper side of one end of the base 1, a rotating component 2 provided at the upper end of the bracket 11, and the rotating component 2 including a first motor 21 fixedly connected to the upper end of the bracket 11, the output shaft of the first motor 21 passing through the bracket 11 and fixedly connected to a bidirectional threaded rod 22, the end of the bidirectional threaded rod 22 near the bracket 11 being rotatably connected to the bracket 11, the end of the bidirectional threaded rod 22 away from the bracket 11 being rotatably connected to a sleeve 23, and the end of the sleeve 23 near the bracket 11 being fixedly connected to the bracket 11, a pushing component 3 provided on the outer side of the bidirectional threaded rod 22, and adjustment components 4 provided at both ends of the base 1, a telescopic component 5 provided at the upper end of the adjustment component 4, and a clamping component 6 provided at the upper end of the telescopic component 5. By cooperating with the rotating component 2 and the pushing component 3, the size of the mold core can be adjusted when processing different paper cup models, effectively increasing the processing range, thereby improving applicability and convenience, and reducing production costs.
[0023] like Figure 4 As shown, the push assembly 3 includes a threaded cylinder 31 with the outer threads of both ends of the bidirectional threaded rod 22 engaged, and a push plate 32 is rotatably connected to the outer end of the threaded cylinder 31.
[0024] like Figure 1 As shown, the push plate 32, away from the threaded cylinder 31, is rotatably connected to the mold core 33 through the sleeve 23. The mold core 33 is tapered. After the bidirectional threaded rod 22 rotates under the support of the sleeve 23, it engages with the threaded cylinder 31, causing the threaded cylinder 31 to push the push plate 32 to move under the restriction of the sleeve 23, thereby allowing the push plate 32 to push the mold core 33 to move for adjustment.
[0025] like Figure 3 As shown, the adjustment assembly 4 includes a second motor 41 fixedly connected to the outer sides of both ends of the base 1, and a one-way threaded rod 42 fixedly connected to the output shaft of the second motor 41 through the base 1. The two ends of the one-way threaded rod 42 are rotatably connected inside the base 1, and a threaded plate 43 is threadedly engaged on the outer side of one end of the one-way threaded rod 42. When the second motor 41 is started, the output shaft of the second motor 41 drives the one-way threaded rod 42 to rotate. After the one-way threaded rod 42 rotates, it engages with the threaded plate 43, causing the threaded plate 43 to drive the moving plate 51 and the electric telescopic rod 52 to move.
[0026] like Figure 1As shown, the telescopic assembly 5 includes a movable plate 51 fixedly connected to the upper end of the threaded plate 43, and an electric telescopic rod 52 is rotatably connected to the upper end of the movable plate 51.
[0027] like Figure 1 As shown, the clamping assembly 6 includes a support plate 61 fixedly connected to the end of the movable plate 51 away from the electric telescopic rod 52, and a clamping plate 62 is rotatably connected to the upper end of the support plate 61. The clamping plate 62 is rotated under the restriction of the support plate 61 by the operation of the electric telescopic rod 52 supported by the movable plate 51, so that the cardboard is sleeved on the outside of the multiple sets of mold cores 33 to make it into a cylindrical shape.
[0028] like Figure 1 As shown, the lower end of the clamping plate 62 is rotatably connected to the electric telescopic rod 52.
[0029] Working principle: When forming the paper cup body, the positions of the mold core 33 and clamping plate 62 are first adjusted according to the cup shape. During adjustment, the first motor 21 is started under the support of the bracket 11. After the first motor 21 starts, the output shaft drives the bidirectional threaded rod 22 to rotate. After the bidirectional threaded rod 22 rotates under the support of the sleeve 23, it engages with the threaded cylinder 31, causing the threaded cylinder 31 to push the push plate 32 to move under the restriction of the sleeve 23. This allows the push plate 32 to push the mold core 33 to move for adjustment. After the adjustment is completed, the first motor 21 is turned off, and then the second motor 41 is started. 1. After startup, the output shaft drives the one-way threaded rod 42 to rotate. After the one-way threaded rod 42 rotates, it engages with the threaded plate 43, causing the threaded plate 43 to drive the moving plate 51 and the electric telescopic rod 52 to move. After the moving plate 51 moves to the appropriate position, the second motor 41 can be turned off. Then, the cardboard to be processed is placed between the two sets of clamping plates 62. The electric telescopic rod 52 rotates under the support of the moving plate 51, causing the clamping plate 62 to rotate under the restriction of the support plate 61, so that the cardboard is fitted on the outside of the multiple sets of mold cores 33 to make it into a cylindrical shape. Then, the connecting end is hot-pressed using a hot pressing device.
[0030] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
