[0028] The utility model provides a bottom punching and forming device for bonding the bottom of a paper cup. Paper is placed on the top of the base, and the punching part is used to drive the bottom punching part to press down, so that the paper is pressed into the punching groove to form a round bottom of the paper cup. It can punch multiple cup bottoms at the same time, improving the punching efficiency. Figure 1-Figure 4 , including: a supporting mechanism 100 and a bottom punching member 200.

[0029] The support mechanism 100 includes a base 110, a bracket 120, a stamping component 130, a stamping plate 140 and a punching slot 150. The top of the base 110 is connected to the stamping component 130 through the bracket 120. The stamping plate 140 is arranged at the bottom of the stamping component 130. The top of the base 110 is provided with a punching slot 150.

[0030] The paper is spread on the top of the base 110 , and the stamping component 130 uses a hydraulic cylinder, and the stamping component 130 drives the stamping plate 140 to rise and fall.

[0031] The bottom punching piece 200 is disposed on the punching plate 140 , and the bottom punching piece 200 is used to punch into the punching groove 150 , so as to punch out the paper into a round bottom of a paper cup.

[0032] Specifically, the bottom punching member 200 includes a connecting rod 210 and a punch 220. The top of the connecting rod 210 is connected to the bottom of the stamping plate 140. The bottom of the connecting rod 210 is provided with a punch 220 corresponding to the punching groove 150. The punch 220 corresponds to the punching groove 150 up and down, and the punch 220 is embedded in the punching groove 150. When the punch 220 contacts the punching groove 150, a dislocated shear force is formed to punch the bottom of the paper.

[0033] Since the cup bottom will remain in the punching groove 150 after punching and is difficult to remove, an empty groove 160 is opened at the bottom of the base 110, and the punching groove 150 is connected to the empty groove 160, so that the punched cup bottom can directly fall from the punching groove 150 into the empty groove 160, making it convenient to remove the punched cup bottom.

[0034] In order to prevent the punched cup bottom from scattering, a collecting component 300 is provided inside the empty groove 160 . The collecting component 300 is inserted into the empty groove 160 , and the punched cup bottom is collected by the collecting component 300 .

[0035] Specifically, the collecting component 300 includes a collecting box 310 and a handle 320. The collecting box 310 is inserted into the empty slot 160. The handle 320 is provided at the front end of the collecting box 310. The collecting box 310 collects the punched cup bottoms. The collecting box 310 is pulled out by the handle 320 to take out the collecting box 310.

[0036] Since the punch bottom piece 200 is easily worn, an external thread is provided on the upper end of the connecting rod 210, and an internal thread connected to the external thread is provided at the bottom of the punch plate 140. The screw connection structure can be disassembled and maintained.

[0037] To improve the stability of the equipment, leveling feet are provided at the four corners of the bottom of the base 110 for adjusting the support stability.

[0038] During specific use, paper is spread on the top of the base 110, the stamping component 130 drives the stamping plate 140 to descend, and the punch 220 is pressed down into the punching groove 150. The punch 220 is used to punch the paper into a circular cup bottom, and the punched cup bottom can directly fall from the punching groove 150 into the empty groove 160. The collection box 310 collects the punched cup bottom, and the collection box 310 is pulled out using the handle 320 to take out the collection box 310.

[0039] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
