Description

Technical Field

[0001] This utility model relates to the field of paper mold forming technology, specifically a four-lower-mold paper mold forming component. Background Technology

[0002] Paper mold forming equipment is a type of equipment used for the production and processing of paper products such as egg trays and cup holders. It typically uses waste newspapers, cardboard boxes, paper tubes, wood pulp, etc. as the main raw materials. After pulping, mixing and other processes, the pulp is prepared into a certain concentration of pulp. Then, the forming mold is placed in the pulp, and the pulp is adhered to the surface of the forming mold by negative pressure adsorption to form a wet paper mold blank. After hot pressing and drying, the wet paper mold blank can be dried to complete the processing of the paper mold.

[0003] Chinese invention patent CN201810174636.6 discloses a paper mold wet blank forming system and a paper mold wet blank forming device. By setting up a slurry tank 12, a rotating shaft 22 is driven to rotate by a rotary drive mechanism 5, so that the mold fixing mechanism 3 enters the slurry tank 12 and the slurry in the slurry tank 12 is adsorbed onto the surface of the lower template. The rotating shaft 22 is driven to rotate again by the rotary drive mechanism 5 to form the paper mold wet blank. However, this paper mold wet blank forming device can only form one paper mold wet blank after the rotating shaft 22 rotates 180 degrees each time. When simply increasing the number of lower templates side by side, it will affect the efficiency of suction negative pressure, resulting in the negative pressure intensity of the lower template closer to the suction pipe being greater than that of the lower template farther away from the suction pipe. As a result, the forming quality and thickness are not easy to control. In order to improve the forming efficiency of paper mold, it is urgent to solve this problem. Utility Model Content

[0004] In view of the problem that the forming quality and thickness are not easy to control when multiple lower molds are set side by side in the existing paper mold forming equipment for forming wet paper mold blanks, this utility model provides a four-lower mold paper mold forming component.

[0005] This utility model discloses a four-lower-mold paper mold forming component, comprising: a lower mold assembly, which includes a vent pipe, lower molds, and a connecting pipe. The four lower molds are installed on the circumferential side of the vent pipe, and two lower molds are arranged side by side. A connecting pipe connects the vent pipe and the lower molds, and the connecting pipe connects the inner cavity of the vent pipe and the surface of the lower molds. A partition plate is provided in the inner cavity of the vent pipe, and the partition plate divides the inner cavity of the vent pipe into four ventilation spaces. One lower mold and one ventilation space are connected through the connecting pipe.

[0006] Preferably, the partition plate is cross-shaped and divides the inner cavity of the ventilator into four ventilator spaces of equal volume.

[0007] Preferably, a four-die paper mold forming component further includes a rotating component, which is disposed at one end of the vent pipe and drives the vent pipe to rotate. The rotating component drives the vent pipe to rotate at an angle of 180 degrees clockwise and 180 degrees counterclockwise.

[0008] Preferably, one end of the ventilator has a driven tooth, and the rotating assembly includes a rotating drive and a rotating transmission. The rotating drive is disposed on one side of the ventilator, and the driving end of the rotating drive is connected to the rotating transmission, and the rotating transmission meshes with the driven tooth.

[0009] Preferably, a four-part paper mold forming component further includes an air supply assembly, wherein a plurality of the air supply assemblies are connected to the end of the air vent, and one air vent corresponds to one air supply assembly.

[0010] Preferably, the gas delivery assembly includes a gas delivery pipe and a rotary joint, wherein the gas delivery pipe is connected to the end of the vent pipe, and the rotary joint is connected between the gas delivery pipe and the rotary joint.

[0011] Preferably, the connecting pipe is S-shaped.

[0012] Preferably, a four-part paper mold forming component further includes a limiting component, which is disposed at one end of the vent pipe and limits the rotation of the vent pipe.

[0013] Preferably, the limiting component includes a limiting drive and a limiting block. The limiting drive is disposed at the end of the vent pipe having the driven tooth, and the limiting block is connected to the driving end of the limiting drive.

[0014] Preferably, the limiting component includes a limiting drive and a limiting block. The limiting drive is disposed at one end of the vent pipe, the limiting block is connected to the driving end of the limiting drive, and a limiting groove is formed at the end of the vent pipe near the limiting block.

[0015] Compared with the prior art, this utility model provides a four-stage lower die paper mold forming component, which has the following beneficial effects:

[0016] This four-lower-mold paper mold forming component features a lower mold assembly with four lower molds. A partition plate divides the inner cavity of the ventilation pipe into four ventilation spaces, with each lower mold connected to a corresponding ventilation space via a connecting pipe. This allows two lower molds to simultaneously draw pulp each time the lower mold rotates into the pulp tank, improving the production efficiency of the paper mold wet blank. Furthermore, the negative pressure intensity of each ventilation space is independently controlled, ensuring uniform quality of the paper mold wet blank. This avoids the situation in traditional paper mold forming equipment where multiple lower molds are arranged side by side for forming the paper mold wet blank, making it difficult to control the forming quality and thickness.

[0026] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0027] The following specific examples illustrate the implementation of this disclosure. Those skilled in the art can easily understand other advantages and effects of this disclosure from the content disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. This disclosure can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this disclosure. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0028] Example 1

[0029] Reference Figures 1-2 , Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 This is a schematic diagram of the lower mold assembly structure of this utility model. A four-lower mold paper mold forming component includes: a lower mold assembly 21, which includes a vent pipe 211, a lower mold 212, and a connecting pipe 213. Four lower molds 212 are installed on the circumferential side of the vent pipe 211, and two lower molds 212 are arranged side by side. The connecting pipe 213 connects the vent pipe 211 and the lower mold 212, and the connecting pipe 213 connects the inner cavity of the vent pipe 211 and the surface of the lower mold 212. The inner cavity of the vent pipe 211 is provided with a partition plate 2111, which divides the inner cavity of the vent pipe 211 into four ventilation spaces 2114. One lower mold 212 and one ventilation space 2114 are connected through the connecting pipe 213, and each ventilation space 2114 can be independently controlled for negative pressure extraction and air blowing, thereby controlling the thickness, moisture content, etc. of each paper mold product to be the same.

[0030] When the ventilation space 2114 is under negative pressure, it can be connected to the lower mold 212 through the connecting pipe 213, so that the surface of the lower mold 212 is also under negative pressure. Then, after the lower mold 212 is rotated into the pulp tank, the pulp can be adsorbed onto the surface of the lower mold 212, thereby forming a wet paper mold blank.

[0031] When the lower mold 212 is moved to the paper mold wet blank transport position, the pressure chamber in the ventilation space 2114 increases, thereby blowing air outward from the surface of the lower mold 212 through the connecting pipe 213, so that the paper mold wet blank can be easily separated from the lower mold 212.

[0032] Specifically, two lower molds 212 arranged side by side form a group, and the two groups of lower molds 212 are located on opposite sides of the vent pipe 211.

[0033] This four-lower-mold paper mold forming component is configured with a lower mold assembly 21 having four lower molds 212. The inner cavity of the vent pipe 211 is divided into four venting spaces 2114 by a partition plate 2111. Each lower mold 212 is connected to a venting space 2114 via a connecting pipe 213. This allows two lower molds 212 to simultaneously suck up pulp each time the lower mold 212 rotates into the pulp tank, improving the production efficiency of the paper mold wet blank. Furthermore, the negative pressure intensity of each venting space 2114 is independently controlled, ensuring uniform quality of the paper mold wet blank. This avoids the situation where the forming quality and thickness are difficult to control when multiple lower molds are arranged side by side in traditional paper mold forming equipment.

[0034] Furthermore, when it is necessary to produce paper mold products with different thicknesses, the thickness of the paper mold products can be controlled by controlling the duration of pulp absorption in the lower mold 212. For example, if one lower mold 212 absorbs pulp while the other lower mold 212 absorbs pulp at a delayed time, the thickness of the two lower molds 212 will differ, thereby producing paper mold wet blanks with different thicknesses, resulting in paper molds with different thicknesses after subsequent processing.

[0035] The partition plate 2111 is in the shape of a cross and divides the inner cavity of the vent pipe 211 into four venting spaces 2114 of the same volume, so that the parameters for controlling the suction and blowing force on the surface of each lower mold 212 can be the same, thereby reducing the difficulty of controlling the thickness of the paper mold product.

[0036] A four-part lower mold paper mold forming component further includes a rotating component 22, which is disposed at one end of the vent pipe 211 and drives the vent pipe 211 to rotate. The rotating component 22 drives the vent pipe 211 to rotate by an angle of 180 degrees clockwise and 180 degrees counterclockwise, so that when controlling the rotation of the vent pipe 211, the vent pipe 211 controls the orientation of the lower mold 212 by reciprocating rotation of 180 degrees.

[0037] One end of the vent pipe 211 has a driven tooth 2112. The rotating assembly 22 includes a rotating drive 221 and a rotating transmission 222. The rotating drive 221 is disposed on one side of the vent pipe 211. The driving end of the rotating drive 221 is connected to the rotating transmission 222, and the rotating transmission 222 meshes with the driven tooth 2112, so that the rotating drive 221 can drive the rotating transmission 222 to rotate. Under the action of the meshing of the rotating transmission 222 and the driven tooth 2112, the driven tooth 2112 is driven to drive the vent pipe 211 to rotate, thereby causing the lower mold 212 to enter the pulp for adsorption and flipping to the bottom of the upper mold for paper mold wet blank transportation.

[0038] A four-stage paper mold forming component also includes an air supply assembly 25. Multiple air supply assemblies 25 are connected to the end of the air pipe 211, and one air space 2114 corresponds to one air supply assembly 25, so that the air pressure intensity in each air space 2114 can be controlled individually by multiple air supply assemblies 25, thereby improving the control capability of the paper mold wet blank thickness.

[0039] By setting up a ventilation pipe 211 and an air supply component 25 that can rotate 180 degrees in both directions, the traditional paper mold forming equipment avoids the situation where the shaft rotates continuously in one direction during paper mold forming, which would cause the two air supply components 25 located at one end of the ventilation pipe 211 to become entangled when applied to the paper mold forming components of this four-part mold.

[0040] The air supply assembly 25 includes an air supply pipe 251 and a rotary joint 252. The air supply pipe 251 is connected to the end of the ventilation pipe 211, and the rotary joint 252 is connected between the air supply pipe 251 and the rotary joint 252. This allows each air supply pipe 251 to individually blow and inhale air into a ventilation space 2114. Furthermore, under the action of the rotary joint 252, when the ventilation pipe 211 rotates 180 degrees counterclockwise or clockwise, the air supply pipe 251 will only experience a small change in position and will not twist, thus ensuring the service life of the air supply pipe 251.

[0041] The connecting pipe 213 is S-shaped. By setting the connecting pipe 213 in an S-shape, when the gas flows between the ventilation space 2114, the lower mold 212 and the connecting pipe 213, the impact force and wear of the gas on the ventilation pipe 211 and the connecting pipe 213 can be reduced, making the gas flow more stable, reducing energy loss and improving the service life of the ventilation pipe 211 and the connecting pipe 213.

[0042] A four-die paper mold forming component further includes a limiting component 26, which is disposed at one end of the vent pipe 211 and limits the rotation of the vent pipe 211. Thus, after the lower die 212 rotates to the designated position, the limiting component 26 can limit the vent pipe 211, ensuring that the lower die 212 is aligned with the upper die component, thereby improving the stability of the pressure applied by the upper die component to the wet paper mold blank and the adsorption effect on the transport of the wet paper mold blank.

[0043] Reference Figure 3 , Figure 3This is a schematic diagram of the rotating component and the limiting component of this utility model. The limiting component 26 includes a limiting drive member 261 and a limiting block 262. The limiting drive member 261 is disposed at one end of the vent pipe 211 with the driven tooth 2112. The limiting block 262 is connected to the driving end of the limiting drive member 261. By setting the limiting drive member 261 and the limiting block 262, after the vent pipe 211 rotates by a specified angle, the limiting block 262 extends out and locks into the driven tooth 2112, thereby limiting the rotation angle of the vent pipe 211.

[0044] Example 2

[0045] Reference Figure 4 , Figure 4 This is another structural schematic diagram of the rotating component and limiting component of this utility model. The difference between this embodiment and the first embodiment is that the limiting component 26 includes a limiting drive member 261 and a limiting block 262. The limiting drive member 261 is disposed at one end of the vent pipe 211, and the limiting block 262 is connected to the driving end of the limiting drive member 261. A limiting groove 2113 is formed at the end of the vent pipe 211 near the limiting block 262, and the limiting block 262 and the limiting groove 2113 have the same shape, so that after the vent pipe 211 rotates to the designated position, the limiting drive member 261 drives the limiting block 262 to extend and lock into the limiting groove 2113, thereby limiting the rotation angle of the vent pipe 211.

[0046] Specifically, there are two limiting grooves 2113, and the two limiting grooves 2113 are located on opposite sides of the vent pipe 211, so that when the vent pipe 211 is limited, it can be limited once every 180 degrees of rotation.

[0047] Specifically, both the limiting groove 2113 and the limiting block 262 are isosceles trapezoids. Under the action of the limiting groove 2113 and the limiting block 262 being isosceles trapezoids, even if the vent pipe 211 rotates beyond a certain angle, it can still be rotated back through the two inclined sides of the limiting groove 2113 and the limiting block 262, further ensuring the alignment effect of the lower mold 212 and the upper mold when transporting the paper mold wet blank.
