Description

Technical Field

[0001] This utility model relates to the technical field of pallet processing equipment, specifically a pallet forming device. Background Technology

[0002] With the increasing demand for cushioning and shock absorption in the packaging industry, foamed pallets, with their advantages of being lightweight, highly elastic, and having good thermal insulation, are being used more and more widely in fields such as electronics, food, and medical devices. Currently, common foamed pallet molding technologies mainly include chemical foaming and physical foaming. Physical foaming involves heating sheet-like materials and then placing them into a stamping press for molding.

[0003] Chinese utility model patent (authorization announcement number CN220661530U) discloses a foaming molding device for pallet processing, including a frame and support wheels; the frame has a processing table inside, an electric clamp on the processing table, a mold at the bottom of the processing table, and a thrust cylinder below the mold; a heating instrument at the top of the frame; support wheels on both sides of the processing table; a dust removal mechanism on one side of the processing table, the dust removal mechanism including a frame and a support frame, the frame on one side of the processing table, an opening for dust discharge at one end of the frame, a through hole for the workpiece to be processed to pass through on the frame, an air blowing component on one side of the frame, the support frame on the side of the frame near the air blowing component, and a moving component on the frame.

[0004] The existing molding apparatus described above produces a pallet by feeding heated foamed material into a press and then using a stamping press to close the mold. However, the material feeding process in this technology has significant drawbacks: when the foamed material is fed into the mold via a conveying structure, the lack of a guiding mechanism makes it prone to displacement during transport. Uneven distribution of the foamed material within the mold not only leads to inconsistent structural strength after pallet molding, resulting in areas that are too thick or too thin, but also affects the overall dimensional accuracy of the pallet, reduces product yield, and increases subsequent rework and scrap disposal costs. Utility Model Content

[0005] The purpose of this utility model is to provide a pallet forming device that guides the foamed material by setting a material limiting component, thereby preventing the material from shifting during the conveying process.

[0006] To address the problems of existing technologies, this utility model application provides a pallet forming device, comprising: a forming machine assembly for pressing foamed material into a pallet; a material guiding assembly for guiding the material and disposed at the inlet and outlet ends of the forming machine assembly; the material guiding assembly includes a material limiting assembly capable of guiding and limiting the material, the material limiting assembly including a plurality of lower guide wheels capable of contacting the lower surface of the material, the material limiting assembly also including a plurality of upper guide wheels capable of moving up and down and contacting the upper surface of the material, and the material limiting assembly also including a plurality of limiting wheels capable of contacting the side of the material and constraining the material to the center position of the forming machine assembly.

The top of the support plate is also provided with a pressing component that can drive the upper guide wheel to move up and down.

[0008] Preferably, the pressing component includes a lifting plate that can move up and down, and an upper guide wheel is rotatably mounted on the lifting plate. The pressing component also includes a second telescopic drive member that can drive the lifting plate to move up and down.

[0009] Preferably, the pressing component includes a movable plate disposed at the output end of the pressing component, and two guide rods are disposed at the bottom of the movable plate. A lifting plate is slidably connected to the guide rods. A spring is sleeved on the outside of the guide rod. The top of the spring is connected to the movable plate, and the other end of the spring is connected to the lifting plate. A sliding rod is also disposed on the movable plate, and the sliding rod is slidably connected to the support plate.

[0010] Preferably, the material guiding component further includes a lifting component that enables the material limiting component to move up and down. The lifting component includes a sliding plate that can reciprocate, and a first slide rail is vertically arranged on the side of the sliding plate, and the first slide rail is slidably engaged with the support plate.

[0011] Preferably, the lifting assembly further includes a third telescopic drive member that is vertically mounted on the slide plate and used to drive the support plate to move up and down.

[0012] Preferably, the material guiding assembly includes a base fixed on the molding machine assembly, and the material guiding assembly includes a second moving mechanism for driving the lifting assembly to reciprocate.

The molding machine assembly also includes a first telescopic drive member mounted on the top of the molding machine body and capable of driving the lower pressure plate to move up and down.

[0014] The advantages of this utility model application compared to the prior art are:

[0015] This application utilizes a material limiting component to guide the foamed material. The limiting wheels in the material limiting component employ an adjustable displacement structure, effectively eliminating lateral offset during material transport by moving the wheels to conform to the material's side. Simultaneously, a dual-wheel pressing unit, consisting of a lower guide wheel and an upper guide wheel, achieves constant pressure clamping and transport of the material, ensuring stable flatness and positional accuracy during transmission. In the material unloading stage after pallet forming, the material limiting component and the forming mechanism are linked for control. After the press-driven mold completes the pallet pressing process, the material forms a concave structure due to the mold cavity constraint and remains within the cavity. At this point, the third telescopic drive component activates, driving the support plate upwards to remove the formed pallet from the mold. As the foamed material continues to be transported, the pallet continues to move forward under the coordinated action of the limiting wheels and guide wheel assembly. Attached Figure Description

Detailed Implementation

[0023] To further understand the features, technical means, and specific objectives and functions achieved by this utility model application, the following detailed description of this utility model application is provided in conjunction with the accompanying drawings and specific embodiments.

[0024] Reference Figures 1-6 As shown, this utility model application provides a pallet forming device, including: a forming machine assembly 1, which is used to press foamed material into a pallet; a material guiding assembly 2, which is used to guide the material and is disposed at the feeding end and the discharging end of the forming machine assembly 1; the material guiding assembly 2 includes a material limiting assembly 21 that can guide and limit the material, the material limiting assembly 21 includes a plurality of lower guide wheels 213 that can contact the lower surface of the material, the material limiting assembly 21 also includes a plurality of upper guide wheels 214 that can move up and down and can contact the upper surface of the material, and the material limiting assembly 21 also includes a plurality of limiting wheels 212 that can contact the side of the material and constrain the material to the center position of the forming machine assembly 1.

[0025] During the pallet forming process, the foamed material first enters the feed end of the material guiding component 2. The material limiting component 21 then comes into play: the lower guide wheel 213 contacts the lower surface of the material, while the upper guide wheel 214 adjusts its position vertically according to the material's thickness and location, contacting the upper surface to limit the material's vertical movement and prevent it from jumping; the limiting wheel 212 contacts the side of the material, constraining it to the center position of the forming machine component 1 to prevent lateral deviation. After being guided and limited by the material guiding component 2, the material enters the forming machine component 1. The forming machine component 1 applies pressure to the foamed material, pressing it down to form a pallet. The formed pallet is output from the discharge end of the forming machine component 1, where it is again guided by the material guiding component 2 to ensure it leaves the forming machine component 1 smoothly and accurately, completing the entire pallet forming process. Through the coordinated work of the material guiding component 2 and the forming machine component 1, the quality and production efficiency of pallet forming are guaranteed.

[0026] The material limiting assembly 21 includes a support plate 211 capable of reciprocating and moving up and down, with a lower guide wheel 213 rotatably mounted on the support plate 211. A pressing assembly 215, capable of driving an upper guide wheel 214 to move up and down, is also provided on the top of the support plate 211. The pressing assembly 215 includes a lifting plate 2151 capable of moving up and down, with the upper guide wheel 214 rotatably mounted on the lifting plate 2151. The pressing assembly 215 also includes a second telescopic drive member 2155 capable of driving the lifting plate 2151 to move up and down. The pressing assembly 215 includes a movable plate 2152 disposed at the output end of the pressing assembly 215, and two guide rods 2153 disposed at the bottom of the movable plate 2152. The lifting plate 2151 is slidably connected to the guide rods 2153. A spring 2154 is sleeved on the outside of the guide rods 2153. The top of the spring 2154 is connected to the movable plate 2152, and the other end of the spring 2154 is connected to the lifting plate 2151. A sliding rod 2156 is also disposed on the movable plate 2152, and the sliding rod 2156 is slidably connected to the support plate 211.

[0027] The second telescopic drive component 2155 drives the moving plate 2152 to move downwards. Because the slide rod 2156 is slidably connected to the support plate 211, the moving plate 2152 moves downwards stably. The moving plate 2152 drives the guide rod 2153 to move downwards, and the lifting plate 2151 also moves downwards under the guidance of the guide rod 2153, causing the upper guide wheel 214, which is rotatably mounted on the lifting plate 2151, to gradually approach the upper surface of the material. When the upper guide wheel 214 contacts the upper surface of the material, the spring 2154 begins to function. If there is a slight change in the material thickness or if it is affected by other external forces, the spring 2154 will elastically expand and contract according to the pressure change, adjusting the position of the lifting plate 2151 to ensure that the upper guide wheel 214 maintains a suitable contact pressure with the upper surface of the material.

[0028] The material guiding assembly 2 also includes a lifting assembly 22 that enables the material limiting assembly 21 to move up and down. The lifting assembly 22 includes a reciprocating slide plate 221, and a first slide rail 222 is vertically arranged on the side of the slide plate 221, and the first slide rail 222 is slidably engaged with the support plate 211. The lifting assembly 22 also includes a third telescopic drive member 223 that is vertically arranged on the slide plate 221 and used to drive the support plate 211 to move up and down.

[0029] After the stamping press drives the mold to complete the pallet pressing process, the material forms a concave structure due to the constraint of the mold cavity and remains in the mold cavity. The third telescopic drive component 223 is activated, driving the support plate 211 to rise and remove the formed pallet from the mold. With the continuous conveying of foamed material, the pallet continues to move forward under the coordinated action of the limit wheel 212, the upper guide wheel 214, and the lower guide wheel 213.

[0030] The material guiding assembly 2 includes a base 24 fixed on the molding machine assembly 1. The material guiding assembly 2 includes a second moving mechanism 23 for driving the lifting assembly 22 to move back and forth. The second moving mechanism 23 includes a transmission screw 231 set at the bottom of the slide plate 221 for driving the slide plate 221 to move back and forth. Rotary driving components 232 are also fixed on both sides of the outside of the base 24. The output end of the rotary driving component 232 is connected to the transmission screw 231. The second moving mechanism 23 also includes a second slide rail 233 set on the base 24 for sliding cooperation with the slide plate 221.

[0031] The rotary drive 232 is activated, and its output end drives the transmission screw 231 to rotate. Since the bottom of the slide plate 221 is threadedly engaged with the transmission screw 231, the slide plate 221 will produce linear motion along the axis of the transmission screw 231 under the action of the rotation of the transmission screw 231. Simultaneously, the slide plate 221 slides against the second slide rail 233 mounted on the base 24. The second slide rail 233 guides the movement of the slide plate 221, ensuring that the slide plate 221 can only move linearly back and forth along the second slide rail 233, preventing the slide plate 221 from deviating or wobbling. As the slide plate 221 reciprocates, the lifting component 22 mounted on the slide plate 221 also moves accordingly, thereby driving the entire material limiting component 21 to move horizontally, adjusting the relative position of the material limiting component 21 and the material.

[0032] The molding machine assembly 1 includes a molding machine body 11 and a worktable 12 that is mounted on the molding machine body 11 and is capable of reciprocating. The molding machine body 11 is also provided with a first moving mechanism 13 that can drive the worktable 12 to move. The molding machine assembly 1 also includes a lower pressure plate 14 that can move up and down. The molding machine assembly 1 also includes a first telescopic drive member 15 that is mounted on the top of the molding machine body 11 and can be used to drive the lower pressure plate 14 to move up and down.

[0033] During the pallet forming process, the mold is mounted on the worktable 12 and the lower pressure plate 14. Material is fed into the mold, and the first moving mechanism 13 starts working, driving the worktable 12 to reciprocate on the molding machine body 11. When the worktable 12 reaches the forming position, the first telescopic drive component 15 starts actuating, driving the lower pressure plate 14 to move downwards. Under the action of the first telescopic drive component 15, the lower pressure plate 14 gradually approaches the material on the worktable 12 and applies pressure to the material. Under the action of pressure, the foamed material deforms in the mold within the molding machine body 11, gradually forming the desired pallet shape.

[0034] The above embodiments only illustrate one or more implementation methods of this utility model application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model application, and these all fall within the protection scope of this utility model application. Therefore, the protection scope of this utility model application should be determined by the appended claims.
