Technical Field
[0001] This utility model belongs to the field of paper cup production technology, and in particular relates to a paper cutting device for paper cup production. Background Technology
[0002] Paper cups are a common beverage container, usually made of paper pulp with a waterproof coating to prevent liquid leakage. Paper cups are characterized by being lightweight, inexpensive, and easy to handle, allowing users to quickly distribute and discard them according to actual needs. Therefore, paper cups are widely used in modern life. In paper cup production, paper is placed into a cutting device, where it is cut into shape by internal blades. Workers then remove the cut paper. However, the blades inside the device are quite sharp, making it easy for workers to be cut and injuring themselves, which affects their safety. To address this, we have proposed a paper cutting device for paper cup production. Utility Model Content
[0003] The purpose of this invention is to provide a paper cutting device for paper cup production. Specifically, by setting up a feeding component, a motor is started, causing a gear two to drive a gear disk two to rotate. When the gear disk two rotates, it drives a gear one, which is rotatably connected to its outer wall, to move synchronously. This causes the gear one to move in a circular motion along the gear disk one. During this motion, the gear one causes the slide rail to move horizontally back and forth. After the paper is cut, the wedge block on the front of the slide rail pushes the paper forward and away from the device, preventing close contact between the worker and the cutting blades. This reduces the risk of injury to the worker and ensures their safety. This invention solves the problem in existing paper cup production where paper is placed in a cutting device, cut by internal blades, and then removed by workers. However, the internal blades are sharp, making workers susceptible to cuts and compromising their safety.
[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a paper cutting device for paper cup production, including a cutting mechanism for cutting paper to make the paper into a shape that conforms to subsequent processing. The cutting mechanism includes an outer box and a bottom cover. Side panels are installed on the left and right sides of the outer box, and two sliding rods are provided in the center of the inside of the side panels, with the two sliding rods on the same horizontal line; The bottom cover is located at the center of the front of the outer box, and a top plate is installed on the top of the side panel; The two side panels are mirror images of the outer box, and the two sliding rods are arranged one on the left and one on the right.
[0005] Furthermore, the cutting mechanism includes a feeding assembly for removing the cut paper from the device; A cutting component is disposed on the front side of the feeding component, and the cutting component is used to position the paper to be cut; The bottom outer wall of the front side of the feeding component abuts against the bottom outer wall of the cutting component.
[0006] Furthermore, the feeding assembly includes a slide rail, which is located at the center of a slide rod. A wedge is installed on the front of the slide rod. A toothed disc is provided on the side of each of the two slide rods that are far apart from each other. A round rod is installed on the side of each of the two toothed discs that are far apart from each other. The round rod on the outer side wall of the toothed disc is installed on the outer side wall of the side plate. By setting two slide rods, it can work on the left and right sides behind the paper stack and push the paper stack forward to leave the equipment. The toothed disc is welded to the outer wall of the side plate via a round rod, and a second toothed disc is sleeved on the outer side of the round rod of the first toothed disc. The top of the front of the wedge is set as an inclined surface.
[0007] Furthermore, the inner wall at the center of the second gear is rotatably connected to the outer wall of the first gear rod. The rear sides of the outer walls of the two second gears are rotatably connected to gears. The two gears are mirror images of each other with the outer box as the center. A protrusion is installed on the side of each gear near the slide rail. By setting the sliding connection between the protrusion of gear one and the inner wall of the slide rail, gear one can drive the slide rod with the slide rail to move forward or backward through the protrusion when it rotates in a circle. In this configuration, the protrusion of one gear extends into the interior of the slide rail and is slidably connected. Limiting blocks are installed on the sides of the two protrusions of one gear that are close to each other.
[0008] Furthermore, gears 2 are meshed and connected to the bottom back of both gear discs 2. The two gears 2 extend outward through the side plate and are rotatably connected on their opposite sides. Motor 1 is provided on the opposite side of each gear 2. Motor 1 is mounted on the outer wall of the side plate. The coupling at the output end of motor 1 is mounted on the outer wall of the side plate. By providing two motors 1, the rotation of the two gears 2 can be controlled separately, so that the parts on the left and right sides can operate independently, preventing the equipment from jamming due to asynchronous movement. The bottom outer wall of the slide rod is fitted with a square plate. The front and back of the two slide rods penetrate the outer wall of the outer box and extend outward. The size and shape of the outer wall of the slide rod are adapted to the size and shape of the interior of the outer box where it is penetrated.
[0009] Furthermore, the cutting assembly includes two trays, which are respectively installed on the left and right sides of the outer wall of the bottom cover. The two trays are mirror images of the bottom cover. A flat plate is installed on the top of the two trays on the side closest to each other. A rectangular box is installed at the center of the top of the flat plate, and a push rod is provided at the center of the rectangular box. By providing the rectangular box, the push rod at the center of the box can be protected to prevent the push rod from being damaged by external factors. The bottom output end of the push rod passes through the flat plate and extends downward. A template is installed at the bottom output end of the push rod, and a shaping tool is installed at the bottom of the template.
[0010] Furthermore, a bidirectional lead screw is provided at the center of the bottom cover, and the bidirectional lead screw is located on the diagonal line inside the bottom cover; the external threads on the left side of the front and the right side of the back of the bidirectional lead screw are mirror images of each other, and the bidirectional lead screw can simultaneously drive two objects to move closer or further apart through the two mirror external threads; The diagonal of the bidirectional lead screw extends from the left side of the front of the bottom cover to the right side of the back cover. The left side of the front and the right side of the back cover of the bidirectional lead screw both extend outward through the bottom cover and are rotatably connected.
[0011] Furthermore, both the bottom of the bottom cover and the top of the top plate are provided with slots, which are on the same diagonal as the bidirectional lead screw. The left and right sides of the outer wall of the bidirectional lead screw are threaded with sliders, and the top and bottom of the sliders are slidably connected to the inner wall of the slots. L-shaped clamps are installed on the top of both sliders. By setting the top and bottom of the sliders to be slidably connected to the slots, the top and bottom of the sliders can be limited to prevent the sliders from deflecting when moving. The top plate has support plates installed on both the front and back sides. The outer walls of the bottom of the two support plates are installed on the outer wall of the front side of the top of the square plate. The L-shaped clamps are L-shaped, and the inner wall dimensions of the two L-shaped clamps on the side closest to each other are adapted to the outer wall dimensions of the template.
[0012] This utility model has the following beneficial effects: 1. This utility model, by setting up a feeding component, specifically, starts a motor to drive a gear to rotate a toothed disc. When the toothed disc rotates, it drives a gear connected to the outer wall to move synchronously, causing the gear to move in a circle along the toothed disc. When the gear moves, it causes the slide rail to move horizontally back and forth. In this way, after the paper is cut, the wedge on the front of the slide rod pushes the paper forward and away from the equipment, avoiding close contact between the worker and the blade, making it less likely for the worker to be cut by the blade during operation, and thus ensuring the safety of the worker during operation.
[0013] 2. This utility model, by setting up a cutting component, specifically places the paper at the center of the top plate, then starts the motor to make the bidirectional lead screw drive the L-shaped clamping plate to move through the slider, so that the two L-shaped clamping plates converge towards the center of the top plate. Then, the push rod is started to move the template downward. In this way, the paper stack of several papers can be positioned to prevent the paper stack from being squeezed and sliding outward when in contact with the template, so that the template can cut the paper stack vertically downward, thereby ensuring the cutting accuracy of the equipment.
[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0019] Please see Figures 1-5 As shown, this utility model is a paper cutting device for paper cup production, including a cutting mechanism 1. The cutting mechanism 1 is used to cut paper so that the paper is shaped to meet the requirements of subsequent processing. The cutting mechanism 1 includes an outer box 111 and a bottom cover 121. Side panels 112 are installed on the left and right sides of the outer box 111. Two sliding rods 1131 are provided in the center of the inside of the side panel 112, and the two sliding rods 1131 are on the same horizontal line. The bottom cover 121 is located at the center of the front of the outer box 111, and the top plate 122 is installed on the top of the side plate 112; the two side plates 112 are mirror images of the outer box 111, and the two slide bars 1131 are arranged on the left and right respectively.
[0020] The cutting mechanism 1 includes a feeding assembly 11, which is used to remove the cut paper from the equipment; The cutting component 12 is located on the front side of the feeding component 11 and is used to position the paper to be cut. The bottom outer wall of the front side of the feeding component 11 abuts against the bottom outer wall of the cutting component 12.
[0021] The feeding assembly 11 includes a slide rail 114, which is located at the center of the slide rod 1131. A wedge block 1132 is installed on the front of the slide rod 1131. A gear disc 1151 is provided on the side of the two slide rods 1131 that is far apart from each other. A round rod is installed on the side of the two gear discs 1151 that is far apart from each other. The round rod on the outer side wall of the gear disc 1151 is installed on the outer side wall of the side plate 112. The gear disc 1151 is welded to the outer side wall of the side plate 112 through the round rod. A gear disc 2 1152 is sleeved on the outer side of the round rod of the gear disc 1151. The top of the front of the wedge block 1132 is set as an inclined surface.
[0022] The inner wall at the center of the second gear 1152 is rotatably connected to the outer wall of the round rod of the first gear 1151. The rear sides of the outer walls of the two gears 1152 that are close to each other are rotatably connected to the first gear 1153. The two gears 1153 are mirror images of each other with the outer box 111 as the center. The side of the first gear 1153 that is close to the slide rail 114 is equipped with a protrusion. The protrusion of the first gear 1153 extends into the interior of the slide rail 114 and is slidably connected. The side of the protrusion of the two gears 1153 that is close to each other is equipped with a limit block 118.
[0023] Both gears 116 are meshed with each other on the bottom back of the two gear discs 1152. The two gears 116 extend outwards through the side plate 112 and are rotatably connected on their opposite sides. A motor 117 is mounted on the opposite side of the side plate 112, and the coupling at the output end of the motor 117 is mounted on the outer wall of the side plate 112. Starting the motor 117 causes the gears 116 to drive the gear discs 1152 to rotate. As the gear discs 1152 rotate, they drive the gear 1153 rotatably connected to the outer wall to move synchronously, causing the gear 1153 to move along the gear discs 1151. The gear 1153 moves in a circular motion, which drives the slide rail 114 to move horizontally back and forth. This allows the paper to be pushed forward and away from the equipment by the wedge 1132 on the front of the slide rod 1131 after it is cut, thus avoiding close contact between the operator and the blade and making it less likely to be cut by the blade during operation, thereby ensuring the safety of the operator. A square plate 119 is installed on the bottom outer wall of the slide rod 1131. The front and back of the two slide rods 1131 penetrate the outer wall of the outer box 111 and extend outward. The size and shape of the outer wall of the slide rod 1131 are adapted to the size and shape of the interior of the outer box 111 where it is penetrated.
[0024] The cutting assembly 12 includes two trays 123, which are respectively installed on the left and right sides of the outer wall of the bottom cover 121. The two trays 123 are mirror images of the bottom cover 121. A flat plate 124 is installed on the top of the two trays 123 on one side close to each other. A rectangular box 1251 is installed at the top center of the flat plate 124. A push rod 1252 is set at the center of the rectangular box 1251. The bottom output end of the push rod 1252 passes through the flat plate 124 and extends downward. A template 126 is installed at the bottom output end of the push rod 1252. A shaping tool is installed at the bottom of the template 126.
[0025] A bidirectional lead screw 1271 is provided at the center of the bottom cover 121. The bidirectional lead screw 1271 is located on the diagonal inside the bottom cover 121. The diagonal of the bidirectional lead screw 1271 extends from the left side of the front of the bottom cover 121 to the right side of the back. The left side of the front and the right side of the back of the bidirectional lead screw 1271 both extend outward through the bottom cover 121 and are rotatably connected.
[0026] Both the bottom of the bottom cover 121 and the top of the top plate 122 have slots 1281. The slots 1281 and the bidirectional lead screw 1271 are on the same diagonal. The left and right sides of the outer wall of the bidirectional lead screw 1271 are threaded with sliders 1282. The top and bottom of the sliders 1282 are slidably connected to the inner wall of the slots 1281. L-shaped clamps 1283 are installed on the top of both sliders 1282. The paper is placed at the center of the top of the top plate 122. Then, the motor 1272 is started, which causes the bidirectional lead screw 1271 to move the L-shaped clamps 1283 through the sliders 1282, so that the two L-shaped clamps 1283 move towards the center of the top of the top plate 122. The paper is gathered together, and then the push rod 1252 is activated to move the template 126 downward. This positions the paper stack, preventing it from being squeezed and sliding outward when in contact with the template 126. This allows the template 126 to cut the paper stack vertically downward, thus ensuring the cutting accuracy of the equipment. Support plates 129 are installed on the front and back of the bottom of the top plate 122. The bottom outer walls of the two support plates 129 are installed on the outer wall of the front side of the top of the square plate 119. The L-shaped clamps 1283 are L-shaped, and the inner wall dimensions of the two L-shaped clamps 1283 on the side closest to each other are adapted to the outer wall dimensions of the template 126.
[0027] One specific application of this embodiment is as follows: First, a waterproof coating is applied to the surface of the paper. Then, a pattern is printed on the outward-facing side of the paper when it is rolled up. Several sheets of paper are then stacked together and placed at the center of the top of the top plate 122. Next, motor 1272 is started, causing the bidirectional lead screw 1271 to rotate. As the bidirectional lead screw 1271 rotates, it drives two sliders 1282 to move closer together via opposite external threads on the left and right sides. The two sliders 1282 slide along the top and bottom slots 1281. The two L-shaped clamps 1283 are brought together towards the center of the top plate 122, positioning the paper stack at the bottom center of the template 126. Then, the push rod 1252 at the center of the rectangular box 1251 is activated. The coupling at the bottom output end of the push rod 1252 pushes the template 126 downward, causing the template 126 to gradually move downward. The blade at the bottom of the template 126 cuts the paper stack clamped by the two L-shaped clamps 1283, cutting the paper stack into several arc shapes that conform to the paper cup making process. After the cutting is completed, the two L-shaped clamps 1283 are reset. Finally, the two motors 117 on the left and right sides of the outer box 111 are started, so that the output end of the motor 117 drives the gear 116 to rotate through the coupling. The gear 116 drives the gear 1152 to rotate along the pin connecting the gear 1151 and the side plate 112 of the cutting assembly through the meshing connection between the gear 1151 and the gear 1152. When the gear 1152 rotates, it also drives the gear 1153 rotatably connected to the outer wall of the side to move, so that the gear 1153 moves along the outer wall of the gear 1151. When gear 1153 performs circular motion, it also causes the protruding part inside the slide rail 114 to slide along the inner wall, thereby driving the slide rod 1131 to continuously move back and forth horizontally. Then, the displacement of the slide rod 1131 drives the wedge block 1132 to move. When the wedge block 1132 moves forward, it pushes the paper stack forward and slides it away from the equipment. Then, the user sorts the paper that has left the equipment, making it neatly arranged, and then sends these neatly arranged papers into the subsequent processing stage.
