Description

Technical Field

[0001] This utility model relates to the technical field of paper plate processing devices, and more specifically, it relates to a paper plate processing device. Background Technology

[0002] Paper trays are typically produced using a thermoforming process, where paper pulp is shaped under high temperature and pressure in a mold. Existing multi-station paper tray processing equipment usually includes three stations: loading, processing, and unloading. During processing, the chassis moves, causing the lower mold to sequentially engage with the upper mold, completing the thermoforming process at multiple stations. However, existing multi-station paper tray processing equipment has the following shortcomings: First, traditional equipment uses only a single set of processing components. The lower mold on the chassis moves sequentially to the same set of upper molds for processing. After each station's processing is completed, the chassis must be in place, limiting the processing cycle to the chassis's movement speed and the upper mold's operating time, making it difficult to improve overall production efficiency. Second, after processing, paper trays are typically removed manually or by simple air blowing. Manual removal is inefficient and poses safety hazards, while air blowing can easily cause tray misalignment or damage, making reliable unloading and transfer difficult. Third, the existing equipment's loading and unloading structures are relatively simple, lacking limits and guidance for paper trays, easily leading to problems such as jamming, stacking, or uneven unloading, affecting the continuous operation of the production line.

[0003] Therefore, there is an urgent need for a paper tray processing device with high processing efficiency, reliable material handling, and smooth loading and unloading to solve the above-mentioned technical problems. Utility Model Content

[0029] Reference Figures 1 to 8 The embodiments of this utility model will be further described below.

[0030] A paper tray processing device includes a base 1. A feeding assembly 22, a discharging assembly 2, and a processing assembly 3 are mounted on the base 1. Two sets of processing assemblies 3 are arranged side-by-side on the base 1 and can operate synchronously, significantly increasing the number of paper trays processed per unit time.

[0031] The processing component 3 includes a chassis 31 movably mounted on a base 1. Multiple lower molds 4 are mounted on the chassis 31, and multiple upper molds 41 are fixedly mounted on the base 1. Each upper mold 41 corresponds to one of the lower molds 4. A power unit is also mounted on the base 1 to drive the chassis 31 to reciprocate. The power unit drives the chassis 31 to move on the base 1, causing each lower mold 4 to sequentially face its corresponding upper mold 41 to achieve processing.

[0032] Each upper mold 41 is equipped with an adsorption component 5, which is used to adsorb the formed paper tray onto the upper mold 41 after processing. The adsorption component 5 firmly adsorbs the paper tray onto the bottom surface of the upper mold 41 by vacuum adsorption, avoiding the problems of paper tray displacement or damage that occur with manual or air-blowing material handling methods.

[0033] The base 1 is also equipped with a discharge support rod 35 and a discharge plate 51. The discharge support rod 35 is fixed to the base 1, and the discharge plate 51 is fixed to the upper end of the discharge support rod 35. The discharge plate 51 is used to receive the processed paper trays, and the last upper mold 41 places the paper trays on the discharge plate 51.

[0034] The feeding assembly 2 includes a feeding plate 211 and a support frame 212. The feeding plate 211 is fixed to the base 1 and has a feeding hole, while the support frame 212 is located above the feeding hole. The support frame 212 is C-shaped with openings on three sides for easy observation and maintenance by the operator. Multiple first cylinders are connected to the bottom of the support frame 212, and each first cylinder is connected to a fixing plate 213. The fixing plate 213 is used to restrict the paper tray from falling, so that the paper tray falls one by one to the predetermined position, avoiding stacking and jamming.

[0035] Several limiting rods 214 are fixed on the support frame 212 to circumferentially limit the paper tray entering the support frame 212 and prevent the paper tray from shifting or rotating during the falling process. An elastic sheet 215 is provided on the feed plate 211 to provide cushioning when the paper tray falls and reduce rigid collisions between the paper tray and the feed plate 211.

[0036] A sliding rod 216 is provided on the feeding plate 211, and a sliding block 217 slides on the sliding rod 216. A connecting rod 218 connecting to the support frame 212 is fixed on the sliding block 217, and the connecting rod 218 is also connected to a second cylinder fixed to the sliding block 217. The feeding assembly 2 also includes a feeding rotating belt 219 located on one side of the feeding plate 211. Through the cooperation of the sliding rod 216, the sliding block 217 and the second cylinder, the support frame 212 can reciprocate above the feeding plate 211 along the direction of the sliding rod 216, orderly arranging and transferring the paper trays onto the feeding rotating belt 219, realizing automated continuous feeding.

[0037] The feeding assembly 22 includes a feeding plate 222 fixed to the base 1 and a gripping member 223. A support rod 224 is fixed to the feeding plate 222, and a rotating rod 225 is rotatably connected to the support rod 224. A feeding frame 226 is connected to the rotating rod 225 to facilitate the placement of raw materials into the feeding frame 226. A feeding hole is formed on the feeding frame 226 to facilitate the gripping member 223 to grip the raw materials. A limit rod is also provided on the feeding frame 226 to limit the circumferential movement of the raw materials. A rotating seat 227 is also fixed to the feeding plate 222, and an adjusting rod is rotatably connected to the rotating seat 227. Adjusting plates 228 are provided on both sides of the adjusting rod, and the gripping member 223 is fixed on the adjusting plate 228. The adjusting rod and adjusting plate 228 can flexibly adjust the position of the gripping member 223 according to the size of the raw materials.

[0038] The gripper 223 includes a gripping rod 232 and a gripping block 233. Multiple adjustment holes 235 are formed on the adjusting plate 228. The gripping rod 232 is fixed to a pair of adjustment holes 235, and the gripping block 233 is fixed to the gripping rod 232 and connected to a suction cup. The multiple adjustment holes 235 provide various installation position options for the gripping rod 232, allowing for flexible adjustment according to the size and shape of the raw material.

[0039] The lower mold 4 has a first folding groove 42 and a second folding groove 43, which are evenly spaced on the lower mold 4. The length of the first folding groove 42 is greater than the length of the second folding groove 43, so as to form a reinforcing rib structure of different depths on the paper material. The upper mold 41, on the opposite side, has a first protrusion and a second protrusion, which are correspondingly arranged with the first folding groove 42 and the second folding groove 43. During the hot pressing process, a reinforcing rib structure is formed on the paper tray, which effectively improves the structural strength and deformation resistance of the paper tray.

[0040] The lower mold 4 has a recessed processing groove 44, with an arc-shaped guide 45 at the entrance of the processing groove 44 and a semi-circular surface 46 at the bottom. The upper mold 41 has protruding processing blocks with processing edges at the bottom. The arc-shaped guide 45 guides the paper tray material as it enters, preventing the material edge from scraping or getting stuck with the mold entrance. The semi-circular surface 46 cooperates with the processing edge to form an arc-shaped structure at the bottom of the paper tray, simultaneously processing it into a disc-bowl shape, increasing the paper tray's load-bearing capacity and stacking stability.

[0041] The lower mold 4 has a recessed bottom groove 49, with an extrusion section 47 formed at the entrance of the bottom groove 49. An arc-shaped section 491 is formed on the extrusion section 47, and an arc-shaped surface is formed at the bottom of the bottom groove 49. The upper mold 41 has a protruding opposite processing block, with an extrusion groove formed at the bottom of the processing block to mate with the extrusion section 47. During processing, the arc-shaped section 491 provides a rounded transition to the edge of the paper tray, eliminating burrs and sharp edges. The fit between the extrusion groove and the extrusion section 47 further improves the forming quality of the paper tray edge.

[0042] The working process of this embodiment is as follows: First, the raw material is fed from the feeding frame 226 by the feeding component 22. The gripper 223 picks up the raw material through the suction cup and transfers it to the lower mold 4 on the chassis 31. The power unit drives the chassis 31 to move, so that the lower mold 4 aligns with each upper mold 41 in sequence for hot pressing. After the processing of each station is completed, the suction component 5 in the upper mold 41 adsorbs the formed paper tray onto the bottom surface of the upper mold 41. The chassis 31 moves, and the next lower mold 4 slides to the lower end of the upper mold 41. The suction component 5 releases the paper tray, allowing it to fall into the next lower mold 4 for further processing. After passing through multiple stations in sequence, the last upper mold 41 places the processed paper tray on the discharge plate 51. After reaching the discharge plate 51, it is moved upward by the cylinder, passing through the elastic sheet 215 and the discharge hole on the discharge plate 211. Subsequently, the cylinder on the sliding block 217 actuates, driving the support frame 212 to move downwards. The first cylinder on the support frame 212 drives the fixing plate 213 to clamp the paper tray. Then, the support frame 212 moves upwards, and the sliding block 217 moves to the position of the unloading rotating belt 219, releasing the paper tray onto the unloading rotating belt 219, completing the unloading. The reciprocating motion of the chassis 31, in conjunction with the two sets of processing components 3, enables each station to work alternately, forming continuous production and significantly improving processing efficiency.

[0043] Paper tray unloading action: After the paper tray reaches the discharge tray 51, the fourth cylinder drives the discharge tray 51 to move upward, passing through the elastic sheet 215 and the discharge hole on the discharge plate 211, so that the paper tray enters the support frame 212. Subsequently, the second cylinder on the sliding block 217 is activated, driving the support frame 212 to move downward along the sliding rod 216 to the clamping position. The first cylinder on the support frame 212 drives the fixing plate 213 to clamp the edge of the paper tray from both sides inward, completing the fixation of the paper tray. Next, the support frame 212 moves upward and reset under the drive of the second cylinder, bringing the paper tray out of the discharge hole. The sliding block 217 moves along the sliding rod 216 to the position of the discharge rotating belt 219. The first cylinder drives the fixing plate 213 to release, and the paper tray is released onto the discharge rotating belt 219 and output by the discharge rotating belt 219. The above process is automatically completed by the sequential action of each cylinder without manual intervention, effectively saving labor costs and improving unloading efficiency and automation.

[0044] The aforementioned paper tray processing device has a compact structure and a high degree of automation. Through multi-station continuous processing and two sets of processing components arranged in parallel, it achieves efficient mass production of paper trays.
