Description

Technical Field

[0001] This utility model belongs to the field of pulp molded product manufacturing technology, specifically relating to a trimming machine for pulp molded product manufacturing. Background Technology

[0002] Pulp molding is a three-dimensional papermaking technology that uses processes such as pulping, adsorption molding, and drying to shape waste paper into products of a specific shape. After the products are manufactured, excess pulp often remains along the edges, affecting usability and aesthetics, thus requiring edge trimming.

[0003] Chinese patent document CN222155702U discloses a trimming machine for producing pulp molded products. The machine places the product on a conveyor belt and conveys it to the right. When the product is conveyed to the bottom of the gantry support frame, the first telescopic cylinder is activated to move downwards and bring the limiting plate against the top of the product. Then, the second telescopic cylinder is activated to adjust the cutting length of the trimming blade. After adjusting to the appropriate position, the third telescopic cylinder is activated to drive the trimming blade downwards to complete the cutting.

[0004] However, in the existing technology, when the size of the product is larger than the length of the cutting blade, it is often necessary to pause the product conveying multiple times to adjust the part of the product to be cut in order to fully complete the cutting work. This method is inefficient. Therefore, a cutting machine for pulp molded product production is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a trimming machine for producing pulp molded products.

[0031] In this embodiment: the feeding assembly 1 includes a frame 101, fixed roller seats 102 are fixedly installed on the front and rear sides of both sides of the frame 101, rotating rollers 103 are movably connected between the fixed roller seats 102 with the same lateral position, a conveyor belt 104 is arranged between the rotating rollers 103, a motor 105 is fixedly installed inside the frame 101, and a pulley 106 is fixedly connected to the front end of one of the rotating rollers 103 and the output end of the motor 105, and a belt 107 is arranged between the pulleys 106;

[0032] The fixed roller seat 102 is rotatably connected to the rotating roller 103, and friction strips are fixedly connected to the outer side of the conveyor belt 104. The friction strips are arranged at equal intervals.

[0033] The frame 101 provides mounting positions for components such as the fixed roller seat 102, motor 105, guide frame 201, and upright frame 301. The fixed roller seat 102 mounts the rotating roller 103 on both sides of the frame 101. The rotating roller 103 mounts the conveyor belt 104. The rotation of the output end of the motor 105 is transmitted to the rotating roller 103 connected to the pulley 106 through the pulley 106 and belt 107. The rotating roller 103 drives the conveyor belt 104 and another rotating roller 103 to rotate.

[0034] In this embodiment: the edge trimming assembly 2 includes a pressure member that can further limit the pulp molded product without affecting its normal conveying, an adjustment member that can adjust the contact effect between the pressure member and the pulp molded product according to the size of the pulp molded product, and a cutting member that can contact the pulp molded product and cut off its excess edges.

[0035] The pressure-applying components include guide frames 201 fixedly installed at the front and rear of the frame 101, a stop block 202 fixedly connected above the guide frame 201, a movable roller seat 203 movably installed inside the guide frame 201, and pressure rollers 204 movably connected between the movable roller seats 203. Synchronous pulleys 205 are fixedly connected to the front and rear ends of one of the rollers 103 and the front and rear ends of the pressure roller 204, respectively. A synchronous belt 206 is provided between the synchronous pulleys 205 at the same longitudinal position. The adjusting components include supports 200 fixedly installed at the front and rear of the frame 101. 7. An electric push rod 208 is provided between the adjacent movable roller seat 203 and the support 207. The cutting part includes a support rod 209 fixedly connected between the stop blocks 202. An L-shaped frame 210 is movably connected to the outer side of the support rod 209. A knife holder 211 is movably mounted on the L-shaped frame 210. A limit rod 212 is provided between the adjacent guide frame 201 and the L-shaped frame 210. A locking knob 213 is provided on one side of the L-shaped frame 210 and both sides of the knife holder 211. A cutting blade 214 is fixedly connected to the side of the knife holder 211 closest to the other knife holder 211.

[0036] The guide frame 201 is provided with a sliding groove. The edges on both sides of the sliding groove are concentric arcs with different radii. The center of the arc coincides with the center line of the rotating roller 103 connected to the synchronous wheel 205. The guide frame 201 is slidably connected to the movable roller seat 203. The movable roller seat 203 is rotatably connected to the pressure roller 204. The movable roller seat 203 and the support 207 are rotatably connected to the electric push rod 208. The guide frame 201 is slidably connected to the limit rod 212. The support rod 209 and the knife holder 211 are slidably connected to the L-shaped frame 210.

[0037] The movable range of the movable roller seat 203 is limited by the guide frame 201 and the stop block 202, allowing the movable roller seat 203 to drive the pressure roller 204 to rotate around the center line of the rotating roller 103 connected to the synchronous wheel 205 when the length of the extension end of the electric actuator 208 changes. The rotation of the rotating roller 103 is transmitted to the pressure roller 204 through the synchronous wheel 205 and the synchronous belt 206. The tail end of the electric actuator 208 is limited by the support 207, and the connection between the support rod 209 and the stop block 202 further improves the position of the roller seat 204. The high-stability guide frame 201 provides an installation position for the L-shaped frame 210. The L-shaped frame 210 is further limited by the limiting rod 212, so that it can only move longitudinally relative to the support rod 209. The cutter 214 that can cut pulp molded products is installed by the cutter holder 211. The position of the L-shaped frame 210 on the support rod 209 or the position of the cutter holder 211 on the L-shaped frame 210 is locked by tightening the locking knob 213 connected to the L-shaped frame 210 or the cutter holder 211 on the L-shaped frame 210.

[0038] In this embodiment: the limiting component 3 includes a vertical frame 301 disposed on one side of the guide frame 201, a limiting frame 302 movably mounted on the vertical frame 301, a limiting roller 303 movably mounted inside the limiting frame 302, and a cylinder 304 fixedly mounted on the vertical frame 301.

[0039] The upright frame 301 is slidably connected to the limiting frame 302, and the limiting frame 302 is rotatably connected to the limiting roller 303. The upright frame 301 provides an installation position for the limiting frame 302 and the cylinder 304, so that the cylinder 304 can stably adjust the longitudinal position of the limiting frame 302. The limiting roller 303, which can move longitudinally with the limiting frame 302, contacts the pulp molded product, thereby limiting the longitudinal range of motion of the pulp molded product without affecting the conveying of the pulp molded product by this trimming machine.

[0040] Working principle: When this edge trimming machine is installed for edge trimming in the production of pulp molded products, the distance between the movable roller seat 203 set between the guide frame 201 and the stop block 202 and the rotating roller 103 connected to the synchronous wheel 205 is fixed. Therefore, when the motor 105 drives the conveyor belt 104 to rotate, by adjusting the transmission ratio between the synchronous wheels 205, the linear speed of the outer side of the pressure roller 204 can always be the same as the speed at which the conveyor belt 104 conveys the pulp molded products.

[0041] Based on this, according to the specifications of the pulp molded product and its position on the edge to be cut when it is centered on the conveyor belt 104, the longitudinal position of the limiting roller 303 can be adjusted by the cylinder 304, the longitudinal position and height of the cutter 214 can be adjusted and locked by loosening and tightening the locking knob 213, and the height of the pressure roller 204 can be adjusted by the electric push rod 208. Thus, after the pulp molded product enters the slitting machine, it is continuously cut by the cutter 214 while being jointly conveyed by the conveyor belt 104 and the pressure roller 204 and jointly limited by the pressure roller 204 and the limiting roller 303.

[0042] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
