[0023] 3. The present invention sets a pushing mechanism. During the process of the upper molding mechanism punching and molding the cut paper through the lower molding mechanism, the upper molding mechanism and the pushing mechanism will position and clamp the cut paper, thereby avoiding the paper being offset due to the downward push of the upper molding mechanism during the punching process, which affects the quality of the cake paper cups obtained by cake molding, thereby ensuring the yield rate and improving the processing quality. After the punching and molding is completed, the molded cake paper cups can always fit on the outer surface of the upper molding mechanism and be pushed out of the lower molding mechanism by the pushing mechanism, further ensuring the quality of the molded cake paper cups.

[0045] During the pressure holding stage of stamping and forming, the electric telescopic rod 1101 is started to shorten the electric telescopic rod 1101, thereby causing the driving plate 1102 to move downward, and the inner driving ring 1104 and the outer driving ring 1106 are driven downward by the inner driving rod 1103 and the outer driving rod 1105 respectively. When the inner driving ring 1104 moves downward, it will slide downward along the inner surface of the first hydraulic groove 907, and the maximum downward sliding distance of the inner driving ring 1104 will be at the top of the discharge end of the injection tube 908, squeezing the hydraulic liquid in the first hydraulic groove 907, so that the hydraulic liquid in the first hydraulic groove 907 enters the first slide groove 903, pushing the first slide plate 904 to slide outward, and then pushing the upper forming strip 906 to move toward the inner surface of the forming seat 1001 through the first connecting plate 905, and the downward movement of the outer driving ring 1106 will push the squeezing ring 1006 along the inner surface of the second hydraulic groove 1002 The surface slides downward, and the maximum downward sliding distance of the extrusion ring 1006 will be at the top of the discharge end of the injection channel 1010, squeezing the hydraulic liquid in the second hydraulic groove 1002, so that the hydraulic liquid in the second hydraulic groove 1002 enters the second slide groove 1007 to push the second slide plate 1008 to slide inward, and then push the lower forming strip 1004 to move toward the outer surface of the forming column 901 through the second connecting plate 1009, thereby increasing the pressure at the fold of the paper formed by the stamping, so that the shapes formed by all the papers meet the forming requirements, avoiding the recovery of the formed cake paper cups under the elasticity of the paper, improving the quality and efficiency of the forming, and this stage is the pressure holding stage, avoiding the scratching and tearing of the paper due to the setting of the shapes of the upper forming mechanism 9 and the lower forming mechanism 10 during the stamping process, thereby improving the quality of the formed cake paper cups and reducing the probability of damage to the formed cake paper cups;

[0046] Before the forming column 901 is about to move upward, the pressure holding stage ends. At the end of the pressure holding stage, the electric telescopic rod 1101 extends, pushing the driving plate 1102 to move upward, and then the inner driving rod 1103 and the outer driving rod 1105 drive the inner driving ring 1104 and the outer driving ring 1106 to move upward, so that the hydraulic liquid in the first slide groove 903 re-enters the first hydraulic groove 907, so that the first slide plate 904 slides inward, and the upper forming bar 906 is driven to move inward through the first connecting plate 905 to fit with the upper forming block 902, and the hydraulic liquid in the second slide groove 1007 re-enters the second hydraulic groove 1002, so that The second slide plate 1008 slides outward, and drives the lower forming strip 1004 to move outward through the second connecting plate 1009, and fits with the lower forming block 1003.

[0047] like Figure 2 , Figure 3 , Figure 7 and Fig.14 As shown, the cake paper cup forming machine also includes: a pushing mechanism 12 installed in the lower forming mechanism 10 for pushing the cake paper cup, the pushing mechanism 12 includes a fixed telescopic rod 1201 fixedly connected to the bottom of the forming seat 1001, the outer surface of the fixed telescopic rod 1201 is sleeved with a connecting spring 1202, the bottom of the fixed telescopic rod 1201 is fixedly connected with a mounting plate 1203, the two ends of the connecting spring 1202 are respectively fixedly connected to the bottom of the forming seat 1001 and the top of the mounting plate 1203, a connecting column 1204 is fixedly connected to the middle position of the top of the mounting plate 1203, the connecting column 1204 passes through the middle of the forming seat 1001 and is slidably connected to the forming seat 1001, the top of the connecting column 1204 is fixedly connected with a pushing plate 1205, the pushing plate 1205 is adapted to the lower forming block 1003 and the lower forming strip 1004, and when the paper is not punched, the top of the pushing plate 1205 is flush with the top of the forming seat 1001.

[0048] When in use, first place the paper cut into a size and shape suitable for stamping on the top of the push plate 1205. When the molding column 901 moves downward to squeeze the paper cut into a size and shape suitable for stamping and pushes the push plate 1205 to move downward, the molding column 901 and the push plate 1205 will be connected due to the setting of the spring 1202, so that the molding column 901 and the push plate 1205 clamp the paper cut into a size and shape suitable for stamping, and the pressure always exists during the process of the paper cut into a size and shape suitable for stamping entering the molding seat 1001 under the action of the molding column 901, and in this process, the molding The molding column 901 squeezes the paper and pushes the push plate 1205 to move downward until the push plate 1205 reaches below the lower molding block 1003 and the lower molding strip 1004 and does not contact the lower molding block 1003 and the lower molding strip 1004. During this process, the mounting plate 1203 is pushed downward by the connecting column 1204, thereby extending the fixed telescopic rod 1201 and stretching the connecting spring 1202, thereby achieving positioning and clamping of the cut paper, avoiding the paper from being offset due to the downward push of the molding column 901 during the stamping process, thereby affecting the quality of the cake paper cups obtained by cake molding, thereby ensuring the yield rate and improving the processing quality;

[0049] After the pressure holding is completed, when the forming column 901 moves upward, the stretched connecting spring 1202 will drive the mounting plate 1203 to move upward, and at the same time drive the fixed telescopic rod 1201 to contract. The upward movement of the mounting plate 1203 will drive the pushing plate 1205 to move upward through the connecting column 1204, so that the pushing plate 1205 pushes the formed cake paper cup out of the forming seat 1001. In the process of pushing the formed cake paper cup out of the forming seat 1001, the formed cake paper cup can always be between the outer surfaces of the forming column 901, the upper forming block 902 and the upper forming strip 906 and the forming seat 1001, the lower forming block 1003 and the lower forming strip 1004, and be pushed out of the forming seat 1001 by the pushing plate 1205, thereby further ensuring the quality of the formed cake paper cup.

[0050] The specific working principle of this cake cup forming machine is as follows:

[0051] When in use, the paper cut into a size and shape suitable for stamping is placed on the top of the forming seat 1001 and on the top of the pushing plate 1205, and then the hydraulic device 4 can be started to make the lifting rod 5 push the lifting plate 6 downward to move downward, and then push the forming column 901, the upper forming block 902 and the upper forming strip 906 downward through the connecting rod 7 and the fixing plate 8 and enter the forming seat 1001 until the bottom of the fixing plate 8 fits with the top of the forming seat 1001, so that the paper cut into a size and shape suitable for stamping is placed on the top of the pushing plate 1205, and then the hydraulic device 4 can be started to make the lifting rod 5 push the lifting plate 6 downward to move downward, and then push the forming column 901, the upper forming block 902 and the upper forming strip 906 downward to move into the forming seat 1001 through the connecting rod 7 and the fixing plate 8. The paper of the stamping size and shape is stamped and formed by the forming column 901, the upper forming block 902, the upper forming strip 906, the forming seat 1001, the lower forming block 1003 and the lower forming strip 1004 to obtain the cake paper cup. In this process, when the forming column 901 moves downward to extrude the paper cut into the size and shape suitable for stamping and pushes the push plate 1205 to move downward, the forming column 901 and the push plate 1205 will be connected due to the setting of the connecting spring 1202, so that the forming column 901 and the pushing plate 1205 clamp the paper cut into a size and shape suitable for stamping and forming, and during the process of the paper cut into a size and shape suitable for stamping and forming entering the forming seat 1001 under the action of the forming column 901, pressure always exists, and during this process, the forming column 901 squeezes the paper and pushes the pushing plate 1205 to move downward until the pushing plate 1205 reaches the bottom of the lower forming block 1003 and the lower forming strip 1004, and does not contact the lower forming block 1003 and the lower forming strip 1004. During this process, the mounting plate 1203 will be pushed downward by the connecting column 1204, thereby extending the fixed telescopic rod 1201 and stretching the connecting spring 1202, thereby achieving positioning and clamping of the cut paper, avoiding the paper from being offset due to the downward push of the forming column 901 during the stamping process, affecting the quality of the cake paper cups obtained by cake forming, thereby ensuring the yield rate and improving the processing quality, and maintaining the pressure for a period of time after the forming is completed;

[0052] During the pressure holding stage of stamping and forming, the electric telescopic rod 1101 is started to shorten the electric telescopic rod 1101, thereby causing the driving plate 1102 to move downward, and the inner driving ring 1104 and the outer driving ring 1106 are driven downward by the inner driving rod 1103 and the outer driving rod 1105 respectively. When the inner driving ring 1104 moves downward, it will slide downward along the inner surface of the first hydraulic groove 907, and the maximum downward sliding distance of the inner driving ring 1104 will be at the top of the discharge end of the injection tube 908, squeezing the hydraulic liquid in the first hydraulic groove 907, so that the hydraulic liquid in the first hydraulic groove 907 enters the first slide groove 903, pushing the first slide plate 904 to slide outward, and then pushing the upper forming strip 906 to move toward the inner surface of the forming seat 1001 through the first connecting plate 905, and the downward movement of the outer driving ring 1106 will push the squeezing ring 1006 along the inner surface of the second hydraulic groove 1002 The surface slides downward, and the maximum downward sliding distance of the extrusion ring 1006 will be at the top of the discharge end of the injection channel 1010, squeezing the hydraulic liquid in the second hydraulic groove 1002, so that the hydraulic liquid in the second hydraulic groove 1002 enters the second slide groove 1007 to push the second slide plate 1008 to slide inward, and then push the lower forming strip 1004 to move toward the outer surface of the forming column 901 through the second connecting plate 1009, thereby increasing the pressure at the fold of the paper formed by the stamping, so that the shapes formed by all the papers meet the forming requirements, avoiding the recovery of the formed cake paper cups under the elasticity of the paper, improving the quality and efficiency of the forming, and this stage is the pressure holding stage, avoiding the scratching and tearing of the paper due to the setting of the shapes of the upper forming mechanism 9 and the lower forming mechanism 10 during the stamping process, thereby improving the quality of the formed cake paper cups and reducing the probability of damage to the formed cake paper cups;

[0053] Before the forming column 901 is about to move upward, the pressure holding stage ends. At the end of the pressure holding stage, the electric telescopic rod 1101 extends, pushing the driving plate 1102 to move upward, and then the inner driving rod 1103 and the outer driving rod 1105 drive the inner driving ring 1104 and the outer driving ring 1106 to move upward, so that the hydraulic liquid in the first slide groove 903 re-enters the first hydraulic groove 907, so that the first slide plate 904 slides inward, and the upper forming bar 906 is driven to move inward through the first connecting plate 905 to fit with the upper forming block 902, and the hydraulic liquid in the second slide groove 1007 re-enters the second hydraulic groove 1002, so that The second slide plate 1008 slides outward, and the lower forming strip 1004 is driven to move outward through the second connecting plate 1009 to fit with the lower forming block 1003. Then, the hydraulic device 4 can be started to make the lifting rod 5 pull the lifting plate 6 to move upward, and then the forming column 901 is driven to move upward through the connecting rod 7 and the fixing plate 8 until the forming column 901 is completely pulled out of the forming seat 1001, and the formed cake paper cup can be removed, so as to avoid the upper forming strip 906 and the lower forming strip 1004 scratching the formed cake paper cup due to excessive extrusion force when the forming column 901 is separated from the forming seat 1001, thereby ensuring the quality of the formed cake paper cup;

[0054] After the electric telescopic rod 1101 is fully extended, the hydraulic device 4 is started to make the lifting rod 5 pull the lifting plate 6 upward to move upward, and then pull the forming column 901 upward through the connecting rod 7 and the fixed plate 8. At this time, the stretched connecting spring 1202 will drive the mounting plate 1203 to move upward, and at the same time drive the fixed telescopic rod 1201 to contract. The upward movement of the mounting plate 1203 will drive the pushing plate 1205 to move upward through the connecting column 1204, so that the pushing plate 1205 pushes the formed cake paper cup out of the forming seat 1001, so that in the process of pushing the formed cake paper cup out of the forming seat 1001, the formed cake paper cup can always be between the outer surfaces of the forming column 901, the upper forming block 902 and the upper forming strip 906 and the forming seat 1001, the lower forming block 1003 and the lower forming strip 1004, and is pushed out of the forming seat 1001 by the pushing plate 1205, which further ensures the quality of the formed cake paper cup;

[0055] After the forming column 901 is completely withdrawn from the forming seat 1001 and the hydraulic device 4 makes the forming column 901 in the initial state, the cake paper cup obtained by stamping can be removed.

[0056] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
