Abstract
Description
Technical Field
[0001] This utility model relates to the field of paper product pressing technology, and in particular to a paper product composite core pressing device. Background Technology
[0002] Paper composite cores are structures made of various paper materials or paper and other materials through a specific process. During the production process, pressing equipment is used to press them together. The working principle of the pressing equipment is based on the principle of material bonding and curing. Pressure and temperature are applied to the composite materials to promote the curing of the adhesive within a certain time, so that a strong bond is formed between the materials.
[0003] For example, CN220562273U discloses a pressing device for paper product processing, including a housing and an adhesive coating device.
[0004] However, in existing technologies, the lamination equipment lacks effective heat preservation measures. During the actual lamination process, the internal heat will be lost to the surrounding environment, which will directly lead to a slower heating rate. The adhesive will cure more slowly in a low-temperature environment and may not achieve the best curing effect. This will result in insufficient bonding strength of the composite core, and delamination and debonding problems are likely to occur during subsequent processing or use. Furthermore, the slow heating will directly lead to a longer lamination time for each batch of products, causing the actual production cycle to exceed expectations and resulting in a decrease in overall production efficiency. Utility Model Content
[0005] The purpose of this invention is to solve the problem that the curing speed of adhesives in the prior art is slower at low temperatures, which may not achieve the best curing effect. This can lead to insufficient bonding strength of the composite core and problems such as delamination and debonding during subsequent processing or use. Therefore, a paper product composite core pressing device is proposed.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a paper product composite core pressing device, including a base, a guide rod fixedly installed on the upper surface of the base, a support plate fixedly installed on the top of the guide rod, an electric cylinder fixedly installed on the upper surface of the support plate, and a heat insulation component fixedly connected to one end of the piston rod of the electric cylinder;
[0007] The insulation component includes a pressing plate, an electric heating block is fixedly installed inside the pressing plate, a baffle is fixedly installed at the edge of the lower surface of the pressing plate, a bearing plate is slidably installed on the upper surface of the base, and a groove is formed inside the bearing plate, the shape of the groove being adapted to the shape of the baffle.
[0008] Preferably, an insulation board is fixedly installed on the upper surface of the pressing plate, and the insulation board is located above the electric heating block.
[0009] Preferably, a connecting block is fixedly installed on the top of the insulation board, and the connecting block is fixedly connected to the piston rod of the electric cylinder.
[0010] Preferably, a connecting plate is fixedly installed on the top of the pressing plate, and the connecting plate is slidably connected to the guide rod.
[0011] Preferably, a sleeve is fixedly installed at the junction of the connecting plate and the guide rod, and the sleeve is sleeved on the outer wall of the guide rod.
[0012] Preferably, a guide plate is fixedly installed at the junction of the base and the bearing plate, and the guide plate is slidably connected to the guide plate.
[0013] Preferably, spring telescopic rods are fixedly installed on both sides of the connecting plate.
[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0015] 1. In this utility model, an electric heating block for heating itself is set separately inside the pressing plate. Before pressing, the electric heating block can preheat the pressing plate in advance, so that the pressing plate will not absorb heat from the core when it comes into contact with the composite core. Furthermore, a baffle is set at the edge of the lower surface of the pressing plate. When the pressing plate presses the composite core, the baffle will enter the groove of the bearing plate to prevent heat leakage from the composite core and play a role in heat preservation.
[0016] 2. In this utility model, by setting an insulation plate above the electric heating block, heat is prevented from being transferred to the electric cylinder, and spring telescopic rods are set at both ends of the connecting plate, which can play a buffering role and avoid excessive impact force from damaging the core.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0024] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides a paper product composite core pressing equipment, including a base 1, a guide rod 2 fixedly installed on the upper surface of the base 1, a support plate 3 fixedly installed on the top of the guide rod 2, an electric cylinder 4 fixedly installed on the upper surface of the support plate 3, and a heat insulation component 5 fixedly connected to one end of the piston rod of the electric cylinder 4.
[0025] The thermal insulation component 5 includes a pressing plate 51, an electric heating block 55 is fixedly installed inside the pressing plate 51, a baffle 57 is fixedly installed at the edge of the lower surface of the pressing plate 51, a bearing plate 53 is slidably installed on the upper surface of the base 1, and a groove 54 is opened inside the bearing plate 53, the shape of the groove 54 is adapted to the shape of the baffle 57.
[0026] An insulation board 59 is fixedly installed on the upper surface of the pressing plate 51. The insulation board 59 is located above the electric heating block 55. A connecting block 510 is fixedly installed on the top of the insulation board 59. The connecting block 510 is fixedly connected to the piston rod of the electric cylinder 4.
[0027] The specific settings and functions of this embodiment are described below. The bearing plate 53 on the upper surface of the base 1 is used to place the paper composite core to be processed. During processing, the terminals of the electric heating block 55 are connected to an external power source. The electric heating block 55 preheats the pressing plate 51 first, and then the electric cylinder 4 is started. The electric cylinder 4 pushes the pressing plate 51 downward to press it above the composite core to complete the pressing and shaping. When the pressing plate 51 contacts the core, the heat in the pressing plate 51 is transferred to the core. The movement of the glue molecules is intensified by heating, which accelerates the chemical reaction between the glue and the surface of the paper product, thereby forming a strong bond in a short time.
[0028] When the pressing plate 51 comes into contact with the core, the baffle 57 at its edge will enter the groove 54 to form a heat insulation barrier at the edge of the core, thereby slowing down the rate of heat loss. In addition, a heat insulation plate 59 is provided above the connection between the pressing plate 51 and the electric heating block 55. The heat insulation plate 59 can slow down the rate at which heat is transferred to the electric cylinder 4, thus protecting the electric cylinder 4.
[0029] The electric cylinder 4 is fixedly installed on the upper surface of the support plate 3, ensuring its structural stability. The insulation plate 59 on the upper surface of the pressing plate 51 is fixedly connected to the piston rod of the electric cylinder 4 through the connecting block 510.
[0030] Example 2: Figure 2 and Figure 3 As shown, a connecting plate 52 is fixedly installed on the top of the pressing plate 51. The connecting plate 52 is slidably connected to the guide rod 2. A sleeve 56 is fixedly installed at the junction of the connecting plate 52 and the guide rod 2. The sleeve 56 is sleeved on the outer wall of the guide rod 2. A guide plate 6 is fixedly installed at the junction of the base 1 and the bearing plate 53. The guide plate 6 is slidably connected to the bearing plate 53. Spring telescopic rods 58 are fixedly installed on both sides of the connecting plate 52.
[0031] The overall effect of this embodiment is that the connecting plate 52 is used to determine the position of the pressing plate 51, and its four corners are slidably connected to the four guide rods 2 respectively. When the electric cylinder 4 pushes the pressing plate 51 to move downward, the connecting plate 52 will drive the sleeve 56 to move along the direction of the guide rod 2. During the downward movement of the pressing plate 51, the spring telescopic rod 58 will first contact the base 1 to play a buffering role and avoid the pressing plate 51 from damaging the core.
[0032] A guide plate 6 is fixedly installed on the upper surface of the base 1 to determine the movement path of the bearing plate 53. After the pressing is completed, the bearing plate 53 is pulled along the direction of the guide plate 6 to bring the core away from the bottom of the pressing plate 51.
[0033] The method of use and working principle of this device: During processing, the composite core of the paper product to be processed is first placed on the bearing plate 53 on the upper surface of the base 1. Then, the wiring terminal of the electric heating block 55 is connected to the external power supply. The electric heating block 55 is used to preheat the pressing plate 51. Then, the electric cylinder 4 is started to push the pressing plate 51 downward, so that the pressing plate 51 is pressed on the top of the composite core to complete the pressing and forming. When the pressing plate 51 contacts the core, the heat in the pressing plate 51 will be transferred to the core. The movement of the glue molecules is intensified by heating, which accelerates the chemical reaction with the surface of the paper product, thereby forming a strong bond in a short time.
[0034] When the pressing plate 51 contacts the core, the baffle 57 at its edge enters the groove 54, forming a heat insulation barrier at the edge of the core to slow down the rate of heat loss. When the electric cylinder 4 pushes the pressing plate 51 downward, the connecting plate 52 drives the sleeve 56 to move along the direction of the guide rod 2. During the downward movement of the pressing plate 51, the spring telescopic rod 58 will first contact the base 1 to buffer the pressure and prevent the pressing plate 51 from damaging the core. After pressing is completed, the bearing plate 53 is pulled along the direction of the guide plate 6 to move the core away from below the pressing plate 51.
[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
