Description

Technical Field

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

[0002] Referring to an existing Chinese patent entitled "A Cup Making Machine" and with the patent publication number "CN207564948U," a cup making machine is described, comprising a frame, a sheet conveying device, a sheet heating device, a forming device, and a cup withdrawing and stacking device. The forming device comprises a thermoforming die, and the cup withdrawing and stacking device comprises a cup withdrawing robot. The thermoforming die comprises an upper die and a lower die; the upper die comprises an upper die, an upper shearing die mounting plate, and multiple upper shearing dies; the lower die comprises a lower die, a lower die body, a lower shearing die mounting plate, multiple lower shearing dies, and multiple forming dies. The thermoforming die is capable of pressing a sheet into a cup. The lower shearing die is provided with a lower shearing blade on the upper outer edge, and an upper shearing blade on the lower inner edge of the upper shearing die. The upper and lower shearing blades cooperate to cut the cup from the sheet, thereby separating the cup from the sheet.

[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 cutting the sheet. 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 when cutting the sheet. As a result, when the lower shearing blade and the upper shearing blade cut the cup from the sheet, it is difficult for the cup to separate from the sheet, resulting in the occurrence of entangled cups, thereby affecting the production efficiency of the cups.

[0016] The bottom of the spiral groove is tilted in its radial direction, so that the spiral knife can not only cut the sheet in a direction parallel to the axial direction of the spiral groove, but also expand in a direction parallel to the radial direction of the spiral groove, thereby being able to tear any possible adhesion between the cup and the sheet, further avoiding the occurrence of cup ligation. In addition, the vertical projection position of the bottom end of the spiral knife on the bottom of the spiral groove is limited, making it easier for the spiral knife to rotate one circle when rotating in the spiral groove, and the spiral knife is also easier to expand during the rotation or compression process, ensuring that the cup and the sheet are completely separated, avoiding the occurrence of cup ligation.

[0017] Furthermore, the torsion spring provided between the spiral blade and the rotating groove can restore the spiral blade to its initial state after rotation, so as to facilitate the next cutting of the sheet. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] 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.

[0025] 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 forming groove 221 is provided on the top surface of the second mold 220, and the cup mold 212 is inserted into the forming 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 forming 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.

[0026] 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.

[0027] 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. The second mold 220 can be set between two rods fixed on the base 100. The two ends of the second mold 220 are respectively slidably set on the rods at both ends through sliders, and the two ends of the second mold 220 are respectively rotatably connected to the sliders at both ends through bearings.

[0028] First mold 210 is positioned above second mold 220, with the cup groove 211 and rotating groove 213 on first mold 210 facing second mold 220. The forming groove 221 and spiral groove 222 on second mold 220 face first mold 210. Cup groove 211 and forming groove 221 correspond to each other, while rotating groove 213 and spiral groove 222 correspond to each other. A mounting ring is rotatably mounted within rotating groove 213 via a bearing. This mounting ring is a circular ring coaxial with rotating groove 213, and a spiral blade 214 is fixed to the side of the mounting ring away from the bottom of rotating groove 213.

[0029] In a direction parallel to the axial direction of the spiral blade 214, the spiral blade 214 can undergo elastic deformation. The spiral blade 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 blade 214 can be inserted into the sheet and can cut the sheet. The spiral groove 222 is a spiral groove body. The spiral direction of the spiral groove 222 is the same as the spiral direction of the spiral blade 214, and the pitch of the spiral blade 214 is greater than the pitch of the spiral groove 222. The spiral blade 214 can extend at least one circle, and the groove body length of the spiral groove 222 is at least greater than the length of the spiral blade 214. For example, the blade body of the spiral blade 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 blade 214 in its spiral direction. The above arrangement makes it easier for the spiral blade 214 to rotate one circle in the spiral groove 222, which is more convenient for completely cutting the sheet.

[0030] Since the bottom of the spiral groove 222 gradually moves away from the notch of the spiral groove 222 in its spiral direction, the bottom of the spiral groove 222 forms a spirally inclined surface. Therefore, when the spiral cutter 214 is inserted into the spiral groove 222, and the second mold 220 approaches the first mold 210 and gradually abuts against the first mold 210, the spiral cutter 214 can contact the bottom of the spiral groove 222 and rotate along the spiral direction of the bottom of the spiral groove 222. During the rotation and compression process of the spiral cutter 214, the spiral cutter 214 can cut the sheet material. 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 it takes 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.

[0031] 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 under the action of the flipping and moving mechanism and gradually presses against the first mold 210. During this process, the end of the spiral blade 214 near the spiral groove 222 first passes through the sheet material. After the spiral blade 214 contacts the bottom of the spiral groove 222, the second mold 220 continues to move closer to the first mold 210. The spiral blade 214 is pushed by the bottom of the spiral groove 222, which enables the spiral blade 214 to rotate. The rotating spiral blade 214 cuts the sheet material. In addition, as the spiral blade 214 is gradually compressed, the part of the spiral blade 214 that has not yet entered the spiral groove 222 also contacts the sheet material and presses and cuts the sheet material.

[0032] 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.

[0033] The first mold 210 and the second mold 220 may both be provided with cylinders or other devices or mechanisms (not shown in the figure) 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 forming groove 221. The plate may be provided with air holes. The second mold 220 is provided with an air duct connected to 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.

[0034] When the first mold 210 and the second mold 220 are pressed against and clamped against the sheet, the cylinder inside the first mold 210 is activated, pushing the cup mold 212 toward the corresponding forming groove 221. During the movement, the cup mold 212 presses on the sheet, pressing the sheet into the shape of a cup. While pushing the sheet, the exhaust device connected to the second mold 220 is activated to exhaust the forming groove 221, creating a negative pressure or vacuum state in the forming groove 221, which is more conducive to the forming of the sheet in the forming 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 when 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.

[0035] The flipping and moving mechanism can move the second mold 220 so that the second mold 220 moves closer to or further 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 can also be replaced with a device that can push an object to move, such as a hydraulic cylinder or an electric push rod. The cylinder can be set on the base 100 and located below the 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 can be installed on the side of the slider away from the second mold 220. The output shaft of the motor can pass through the slider and the bearing thereon and be fixedly connected to the second mold 220. In this embodiment, the second mold 220 can be raised and lowered on the base 100 by the cylinder, and the second mold 220 can be rotated by the motor.

[0036] The working principle of this embodiment is: 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. In the process of the second mold 220 approaching 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 insert into the corresponding spiral groove 222 and contact with the bottom of the spiral groove 222. The first mold 210 is further pushed close to the second mold 220 by the flipping and moving mechanism. Under the action of the bottom of the spiral groove 222, the spiral knife 214 contacts the bottom of the spiral groove 222 and rotates along the 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. 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 and second molds 210, so that the sheet is formed in the forming groove 221. After the sheet is formed into a cup, the cup mold 212 is controlled to retract into the corresponding cup groove 211. Then, the second mold 220 is moved away from the first mold 210 by controlling the cylinder in the flipping mechanism. When the second mold 220 is a certain distance away from the first mold 210, the motor in the flipping mechanism is activated, which drives the second mold 220 to rotate so that the forming groove 221 no longer faces the cup groove 211. Finally, the formed cup is pushed or blown out of the forming groove 221 by the cylinder in the second mold 220 or the air extraction and exhaust device connected to the forming groove 221. The cup that has left the second mold 220 is then collected, completing the cup production.

[0037] 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 contraction speed of the cylinder and the rotation speed of the motor are well controlled.

[0038] The spiral blade 214 in this embodiment can completely cut the sheet, so that the cup can be completely removed from the sheet without causing the cup to be connected to the sheet, thereby avoiding the occurrence of connected cups and improving the production efficiency of the cups.

[0039] 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.

[0040] The width of the spiral blade 214 is smaller than the width of the spiral groove 222. As the spiral blade 214 is pressed into the spiral groove 222, it is subjected not only to forces in the spiral direction from the bottom of the spiral groove 222 but also to forces in the radial direction from the bottom of the spiral groove 222. The force in the spiral direction from the bottom of the spiral groove 222 causes the spiral blade 214 to rotate, while the force in the radial direction from the bottom of the spiral groove 222 increases the radius of each turn of the spiral blade 214, causing it to expand. This allows the spiral blade 214 to expand outward while cutting the sheet material. The expanded spiral blade 214 can tear or pull any adhesions between the cup and the sheet material, ensuring complete separation between the cup and the sheet material and ensuring that the spiral blade 214 can completely cut the sheet material.

[0041] In the initial state, the projection of the end of the spiral blade 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 .

[0042] 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.

[0043] In some embodiments, a torsion spring (not shown) is provided between the spiral blade 214 and the rotating groove 213. The torsion spring is positioned between the mounting ring and the rotating groove 213. One end of the torsion spring is fixedly connected to the mounting ring, while the other end is inserted into and fixed to the bottom of the rotating groove 213. The torsion spring enables the spiral blade 214 to return to its initial state after rotation, facilitating the next cutting of the sheet material.

[0044] In some embodiments, two mounting frames 300 are fixed to the base 100, and the two mounting frames 300 are located on either side of the base 100. The first mold 210 and the second mold 220 are both mounted between the two mounting frames 300. A movable plate 310 is slidably disposed within each mounting frame 300. The first mold 210 is located above the second mold 220. The first mold 210 is fixedly connected between the two mounting frames 300, and the second mold 220 is rotatably disposed between the two movable plates 310.

[0045] The mounting frame 300 is an inverted U-shaped frame, and the movable plate 310 is slidably mounted between the frame beams on both sides of the mounting frame 300 via a sliding structure such as a guide rail or a slide groove. The first mold 210 is fixed between the top beams of the two mounting frames 300, and the second mold 220 is rotatably mounted between the two movable plates 310 via a rotating structure such as a rotating shaft or a bearing.

[0046] In this embodiment, the flipping and moving mechanism includes a flipping assembly, a moving assembly and a power assembly 600. The flipping assembly is arranged on one side of the moving assembly. The flipping assembly is used to flip the second mold 220 so that the produced cup can be separated from the second mold 220. The moving assembly is used to move the second mold 220 so that the first mold 210 and the second mold 220 can be closed or demolded. The power assembly 600 is used to provide power for the flipping assembly to flip the second mold 220, and to provide power for the moving assembly to move the second mold 220.

[0047] Among them, the flipping assembly includes a first push rod 401, a second push rod 402, a linkage rod 403, a flip pull rod 404 and a first cam 405. The first push rod 401 and the second push rod 402 are both rotatably set on the base 100.
