Description

Technical Field

[0001] The invention relates to the technical field of cup making machines, and in particular to a full-automatic cup turning molding machine. Background Art

Then the separation of the cup and the sheet is realized.

[0003] The above-mentioned prior art has the following defects. Since the upper shearing die and the lower shearing die correspond to each other, there may be a gap between the lower shearing blade at the outer edge of the upper end of the lower shearing die and the upper shearing blade at the inner edge of the lower end of the upper shearing die when they cut the sheet material. Moreover, as the cup making machine works for a long time or as the equipment ages, the gap between the lower shearing blade and the upper shearing blade is likely to increase further, which may make it difficult to completely cut the sheet material when cutting the sheet material. As a result, when the lower shearing blade and the upper shearing blade cut the cup from the sheet material, it is difficult for the cup to be separated from the sheet material, resulting in the occurrence of a lingering cup, thereby affecting the production efficiency of the cup.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature.

[0035] like Figures 1 to 7 As shown, an embodiment of the present invention provides a fully automatic flip molding cup machine, which includes a base 100, a cup making mechanism 200 and a flip moving mechanism. The cup making mechanism 200 is arranged on the base 100. The cup making mechanism 200 includes a first mold 210 and a second mold 220. The first mold 210 and the second mold 220 are arranged in cooperation for producing cups.

[0036] The flipping and moving mechanism is arranged on the base 100, and the flipping and moving mechanism is used to flip and move the second mold 220; a cup groove 211 is provided at the bottom of the first mold 210, and a cup mold 212 is provided in the cup groove 211; a molding groove 221 is provided on the top surface of the second mold 220, and the cup mold 212 is inserted into the molding groove 221 to process the sheet into a cup; a rotating groove 213 is provided at the bottom of the first mold 210 coaxially with the cup groove 211, and a spiral knife 214 is rotatably arranged in the rotating groove 213; a spiral groove 222 is provided on the top of the second mold 220 coaxially with the molding groove 221, and the spiral knife 214 is inserted into the spiral groove 222 and can rotate along the spiral groove 222 and can cut the sheet arranged between the first mold 210 and the second mold 220.

[0037] In this embodiment, the base 100 can be a metal plate or metal frame with strong supporting capacity. The cup-making mechanism 200 and the flipping and moving mechanism are both arranged on the base 100. The first mold 210 and the second mold 220 in the cup-making mechanism 200 can be some existing metal molds, and the cup-making method can be through hot pressing molding.

[0038] The first mold 210 and the second mold 220 are arranged opposite to each other. The first mold 210 can be fixed on the base 100 by two fixing rods, and the second mold 220 can be arranged between two rods fixed on the base 100. The two ends of the second mold 220 are respectively slidably arranged on the rods at both ends through sliders, and the two ends of the second mold 220 are respectively rotatably connected with the sliders at both ends through bearings.

[0039] The first mold 210 is located above the second mold 220, and the cup groove 211 and the rotating groove 213 provided on the first mold 210 are both oriented toward the second mold 220, and the molding groove 221 and the spiral groove 222 provided on the second mold 220 are oriented toward the first mold 210. The cup groove 211 corresponds to the molding groove 221, and the rotating groove 213 corresponds to the spiral groove 222. A mounting ring is rotatably provided in the rotating groove 213 through a bearing, and the mounting ring is a circular ring coaxially provided with the rotating groove 213, and the spiral cutter 214 is fixed on the side of the mounting ring away from the bottom of the rotating groove 213.

[0040] In a direction parallel to the axial direction of the spiral cutter 214, the spiral cutter 214 can be elastically deformed. The spiral cutter 214 can be an annular spring, and the upper and lower end faces of its single turn are both blades, which ensures that the spiral cutter 214 can be inserted into the sheet and can cut the sheet. The spiral groove 222 is a spiral groove body, and the spiral direction of the spiral groove 222 is the same as the spiral direction of the spiral cutter 214, and the pitch of the spiral cutter 214 is greater than the pitch of the spiral groove 222. The spiral cutter 214 can extend at least one circle, and the groove length of the spiral groove 222 is at least greater than the length of the spiral cutter 214. For example, the blade body of the spiral cutter 214 extends 1.2 circles in its spiral direction, and the groove body of the spiral groove 222 extends 1.2 times the length of the spiral cutter 214 in its spiral direction. The above arrangement makes it easier for the spiral cutter 214 to rotate one circle in the spiral groove 222, and it is easier to completely cut the sheet.

[0041] Since the bottom of the spiral groove 222 gradually moves away from the notch of the spiral groove 222 in the spiral direction, the bottom of the spiral groove 222 is a spiral inclined surface. Therefore, when the spiral cutter 214 is inserted into the spiral groove 222, in the process of the second mold 220 approaching the first mold 210 and gradually pressing against the first mold 210, the spiral cutter 214 can contact the bottom of the spiral groove 222 and can rotate along the spiral direction of the bottom of the spiral groove 222. In the process of the spiral cutter 214 rotating and compressing, the spiral cutter 214 can cut the sheet. In addition, since the pitch of the spiral knife 214 is greater than the pitch of the spiral groove 222, the inclination angle of a single turn of the spiral knife 214 is greater than the inclination angle of a single turn of the spiral groove 222. When the inclination angle of a single turn of the spiral groove 222 is constant, the larger the inclination angle of the spiral knife 214, the longer the time required for the spiral knife 214 to contact the bottom of the spiral groove 222 when sliding along the spiral groove 222, and the more difficult it is to contact the bottom of the spiral groove 222, which can better ensure the normal rotation of the spiral knife 214 in the spiral groove 222 and ensure the normal cutting of the sheet.

[0042] In this embodiment, when the sheet material is heated and softened and then conveyed between the first mold 210 and the second mold 220, the second mold 220 gradually approaches the first mold 210 and gradually presses against the first mold 210 under the action of the flipping and moving mechanism. The end of the spiral cutter 214 close to the spiral groove 222 first passes through the sheet material. After the spiral cutter 214 contacts the bottom of the spiral groove 222, the second mold 220 continues to approach the first mold 210. The spiral cutter 214 is pushed by the bottom of the spiral groove 222, so that the spiral cutter 214 can rotate, and the rotating spiral cutter 214 cuts the sheet material. In addition, as the spiral cutter 214 is gradually compressed, the part of the spiral cutter 214 that has not yet entered the spiral groove 222 also contacts the sheet material and presses and cuts the sheet material.

[0043] When the second mold 220 is pressed against the first mold 210, at least one circle of the spiral knife 214 is completely extended into the spiral groove 222. In this case, the end of the spiral knife 214 away from the rotating groove 213 rotates at least one circle along the spiral groove 222, which means that the end of the spiral knife 214 away from the rotating groove 213 rotates at least one circle relative to the sheet, thereby achieving complete cutting of the sheet.

[0044] The first mold 210 and the second mold 220 may both be provided with devices or mechanisms (not shown in the figure) such as cylinders that can push the parts to move. Taking the cylinder as an example, the cylinder in the first mold 210 can push the cup mold 212 set in the cup groove 211 to extend out of the cup groove 211. The second mold 220 is provided with a plate parallel to the bottom of the molding groove 221. The plate may be provided with air holes. The second mold 220 is provided with an air duct connected with the air hole. The air duct can be connected to the air extraction and exhaust equipment set outside the first mold 210 through an air pipe. The output shaft of the cylinder set in the second mold 220 is fixedly connected to the plate in the second mold 220.

[0045] When the first mold 210 and the second mold 220 are pressed against and clamped to clamp the sheet, the cylinder in the first mold 210 is started, and the cylinder in the first mold 210 pushes the cup mold 212 and moves toward the corresponding molding groove 221. During the movement, the cup mold 212 presses on the sheet and presses the sheet into the shape of a cup. When pushing the sheet, the exhaust and exhaust equipment connected to the second mold 220 is started to exhaust the molding groove 221, so that the molding groove 221 forms a negative pressure or vacuum state, which is more conducive to the molding of the sheet in the molding groove 221. When the sheet has been formed in the forming groove 221, the cylinder in the first mold 210 drives the cup mold 212 to retract into the cup groove 211. Under the action of the flipping and moving mechanism, the second mold 220 gradually moves away from the first mold 210 and flips. After flipping to a suitable angle, or the forming groove 221 of the second mold 220 no longer corresponds to the cup groove 211 of the first mold 210, the cylinder in the second mold 220 can be controlled to push the formed cup out of the forming groove 221, or the forming groove 221 can be directly blown by the air extraction and exhaust equipment to blow the formed cup directly out of the forming groove 221, thereby completing the processing of the cup.

[0046] The flipping and moving mechanism can move the second mold 220 so that the second mold 220 approaches or moves away from the first mold 210. The flipping and moving mechanism may include a cylinder for driving the second mold 220 to rise and fall and a motor for driving the second mold 220 to rotate. The cylinder may also be replaced by a device that can push an object to move, such as a hydraulic cylinder or an electric push rod. The cylinder may be arranged on the base 100 and located below a slider that is rotatably connected to the second mold 220. The output shaft of the cylinder faces the corresponding slider and is fixedly connected to the corresponding slider. The motor may be installed on the side of the slider away from the second mold 220. The output shaft of the motor may pass through the slider and the bearing thereon and be fixedly connected to the second mold 220. In this embodiment, the lifting and lowering of the second mold 220 on the base 100 may be achieved by the cylinder, and the rotation of the second mold 220 may be achieved by the motor.

[0047] The working principle of this embodiment is:

[0048] First, the heated sheet is placed between the second mold 220 and the first mold 210, and then the second mold 220 is pushed close to the first mold 210 by the flipping and moving mechanism. When the second mold 220 is close to the first mold 210, the end of the spiral knife 214 on the first mold 210 away from the rotating groove 213 will first pass through the sheet, and then be inserted into the corresponding spiral groove 222, and contact with the groove bottom of the spiral groove 222. The first mold 210 is continuously pushed close to the second mold 220 by the flipping and moving mechanism. Under the action of the groove bottom of the spiral groove 222, the spiral knife 214 contacts with the groove bottom of the spiral groove 222 and rotates along the groove bottom of the spiral groove 222. When at least one circle of the spiral knife 214 is inserted into the spiral groove 222, it means that the spiral knife 214 has completed cutting the sheet.

[0049] When the second mold 220 and the first mold 210 clamp the sheet, the cup mold 212 in the first mold 210 is controlled to press against the sheet sandwiched between the first mold 210 and the second mold 220, so that the sheet is formed in the molding groove 221. After the sheet is formed into a cup, the cup mold 212 is controlled to retract into the corresponding cup groove 211, and then the second mold 220 is controlled to move away from the first mold 210 by controlling the cylinder in the flipping and moving mechanism. When the second mold 220 moves away from the first mold 210 for a certain distance, the motor in the flipping and moving mechanism is started, and the motor drives the second mold 220 to rotate, so that the molding groove 221 is no longer opposite to the cup groove 211. Finally, the molded cup is pushed out or blown out of the molding groove 221 by the cylinder set in the second mold 220 or the exhaust gas device connected to the molding groove 221, and then the cup separated from the second mold 220 is collected to complete the production of the cup.

[0050] Of course, when the flipping and moving mechanism controls the movement of the second mold 220, the movement and flipping can also be performed simultaneously, as long as the extension and retraction speed of the cylinder and the rotation speed of the motor are well controlled.

[0051] The spiral blade 214 in this embodiment can completely cut the sheet material, so that the cup can be completely removed from the sheet material without causing the cup to be connected to the sheet material, thereby avoiding the occurrence of connected cups and thus improving the production efficiency of the cups.

[0052] In some embodiments, the bottom of the spiral groove 222 is inclined in the radial direction of the spiral groove 222, that is, it is inclined in a direction parallel to the radial direction of the forming groove 221, and its inclination direction is from the inner groove wall of the spiral groove 222 to the outer groove wall of the spiral groove 222 in the direction away from the spiral knife 214.

[0053] The width of the spiral blade 214 is smaller than the width of the spiral groove 222. When the spiral blade 214 is pressed into the spiral groove 222, it is subjected not only to the force in the spiral direction of the bottom of the spiral groove 222 but also to the force in the radial direction of the bottom of the spiral groove 222. The force in the spiral direction of the bottom of the spiral groove 222 can cause the spiral blade 214 to rotate, and the force in the radial direction of the bottom of the spiral groove 222 can increase the radius of a single turn of the spiral blade 214, and can cause the spiral blade 214 to expand, thereby causing the spiral blade 214 to expand outward while cutting the sheet. The expanded spiral blade 214 can tear or pull the possible adhesion between the cup and the sheet to ensure that the cup and the sheet are completely separated and that the spiral blade 214 can completely cut the sheet.

[0054] In the initial state, the projection of one end of the spiral cutter 214 away from the rotating groove 213 on the bottom surface of the spiral groove 222 is close to the starting end of the spiral groove 222 and close to the inner groove wall of the spiral groove 222 .

[0055] The above arrangement makes it easier for the spiral knife 214 to rotate one circle when rotating in the spiral groove 222, and the spiral knife 214 is easier to expand during the rotation process or compression process, ensuring that the spiral knife 214 can cut the sheet more completely.

[0056] In some embodiments, a torsion spring (not shown) is provided between the spiral blade 214 and the rotating groove 213. The torsion spring is provided between the mounting ring and the rotating groove 213, one end of the torsion spring is fixedly connected to the mounting ring, and the other end is inserted into and fixed to the bottom of the rotating groove 213. The torsion spring can restore the spiral blade 214 to its initial state after rotation, so as to facilitate the next cutting of the sheet.
