Description

Technical Field

[0001] This utility model relates to the technical field of UV-curable release paper production equipment, and in particular to a photoinitiator addition device for UV-curable release paper. Background Technology

[0002] UV-curable release paper is a type of special paper made from base paper. A release agent coating that can be rapidly cured under ultraviolet light is applied to its surface, giving the paper good release properties. It can be easily separated from various adhesive materials without leaving any residue or affecting the properties of the adhesive materials after separation. When producing UV-curable release paper, the coating liquid needs to be prepared in advance using appropriate mixing equipment. The release agent and a portion of the solvent are mixed evenly, and then photoinitiators and other additives are added. The mixture is then stirred until it is completely dissolved and evenly dispersed.

[0003] Photoinitiators can clump together due to prolonged storage. If the photoinitiator is added directly to the mixing equipment, the clumped photoinitiator cannot be fully mixed with the release agent inside the mixing tank, thus affecting the quality of the coating solution. Utility Model Content

[0004] The purpose of this invention is to solve the problem that photoinitiators in the prior art will clump together due to long-term storage. If the photoinitiator is added directly to the mixing equipment, the clumped photoinitiator cannot be fully mixed with the release agent inside the mixing tank, thus affecting the quality of the coating liquid. Therefore, a photoinitiator adding device for UV-curable release paper is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a photoinitiator addition device for UV-curable release paper, comprising an agglomeration and crushing chamber, wherein an agglomeration screen is provided inside the agglomeration and crushing chamber, an electric telescopic rod is fixedly installed at the center of the agglomeration and crushing chamber, the drive end of the electric telescopic rod is fixedly installed at the center of one side of the agglomeration screen, one end of the agglomeration and crushing chamber is fixedly connected to a plurality of feed inlets, and the other end of the agglomeration and crushing chamber is fixedly connected to a discharge outlet.

[0006] Preferably, the inside of the agglomeration and crushing chamber is fixedly installed with several limiting rods arranged in a ring, and one end of the limiting rods moves through the inside of the agglomeration screen.

[0007] Preferably, a top hole device is fixedly installed at the bottom of the agglomeration and crushing chamber.

[0008] Preferably, the top hole device includes a mounting ring and several top hole rods, one end of each of the several top hole rods is fixedly connected to one side of the mounting ring, and the several top hole rods are respectively located directly below the screen holes in the clumping screen.

[0009] Preferably, one end of the discharge port is located at the center of the mounting ring.

[0010] Preferably, a support frame is fixedly connected to the outside of the agglomeration and crushing chamber, and a mounting base plate is fixedly connected to one end of the support frame.

[0011] Preferably, a feeding ring is fixedly connected to the other end of several of the feeding ports, and a feeding pipe is fixedly connected to one side of the feeding ring.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, the raw material is introduced into the inside of the feeding ring through the feeding pipe, and then enters the inside of the four feed ports from the inside of the feeding ring, falling evenly into the inside of the agglomeration and crushing chamber. The photoinitiator particles that meet the mixing size requirements pass through the agglomeration screen and enter the bottom of the agglomeration and crushing chamber, while the agglomerates are screened out by the agglomeration screen. At the same time, the electric telescopic rod drives the agglomeration screen to move back and forth up and down, so as to break the agglomerates and prevent the agglomerated photoinitiator from entering the inside of the mixing equipment for mixing, thereby improving the quality of the coating liquid.

[0014] 2. In this utility model, by driving the agglomerating screen to move downward, the top hole rod in the top hole device will pass through the filter holes of the agglomerating screen, pushing out the photoinitiator raw material blocked in the filter holes. At the same time, the agglomerates located on one side of the agglomerating screen are impacted by the top hole rod and broken, further improving the breaking efficiency. Attached Figure Description

One end of the agglomeration and crushing chamber 1 is fixedly connected to several inlets 11, and the other end of the agglomeration and crushing chamber 1 is fixedly connected to an outlet 12. Several limiting rods 13 are fixedly installed in a ring arrangement inside the agglomeration and crushing chamber 1. One end of the limiting rods 13 moves through the interior of the agglomeration screen 2. A support frame 14 is fixedly connected to the outside of the agglomeration and crushing chamber 1. One end of the support frame 14 is fixedly connected to a mounting base plate 141. The other end of the several inlets 11 is fixedly connected to a feeding ring 111. One side of the feeding ring 111 is fixedly connected to a feeding pipe 112.

[0023] The specific settings and functions of this embodiment are described below. The photoinitiator raw material is introduced into the inside of the feeding ring 111 through the feeding pipe 112, and then enters the inside of the four feed ports 11 from the inside of the feeding ring 111, falling evenly into the inside of the agglomeration and breaking chamber 1. The photoinitiator particles that meet the mixing size requirements pass through the agglomeration screen 2 and enter the bottom of the agglomeration and breaking chamber 1, while the agglomerates are screened out by the agglomeration screen 2. At the same time, the electric telescopic rod 3 drives the agglomeration screen 2 to move up and down reciprocally, so that the agglomerates are broken, preventing the agglomerated photoinitiator from entering the inside of the mixing equipment for mixing, thereby improving the quality of the coating liquid.

[0024] Example 2: Figure 1 - Figure 4As shown, the photoinitiator addition device for UV-curable release paper in this utility model includes an agglomeration and crushing chamber 1. An agglomeration screen 2 is provided inside the agglomeration and crushing chamber 1. An electric telescopic rod 3 is fixedly installed at the center of the agglomeration and crushing chamber 1. The driving end of the electric telescopic rod 3 is fixedly installed at the center of one side of the agglomeration screen 2. One end of the agglomeration and crushing chamber 1 is fixedly connected to several feed ports 11. The other end of the agglomeration and crushing chamber 1 is fixedly connected to a discharge port 12. A top hole device 4 is fixedly installed at the bottom of the agglomeration and crushing chamber 1. The top hole device 4 includes a mounting ring 41 and several top hole rods 42. One end of each of the several top hole rods 42 is fixedly connected to one side of the mounting ring 41. The several top hole rods 42 are respectively located directly below the screen holes in the agglomeration screen 2. One end of the discharge port 12 is located at the center of the mounting ring 41.

[0025] The overall effect of this embodiment is that when the electric telescopic rod 3 drives the clumping screen 2 to move up and down reciprocally, the clumping screen 2 moves downward, and the top hole rod 42 in the top hole device 4 passes through the filter holes of the clumping screen 2, pushing out the photoinitiator raw material that is blocked in the filter holes. At the same time, the clumping blocks located on one side of the clumping screen 2 are impacted by the top hole rod 42 and break, further improving the breaking efficiency.

[0026] The operating method and working principle of this device are as follows: The photoinitiator raw material is introduced into the inside of the feeding ring 111 through the feeding pipe 112, and then enters the inside of the four feed ports 11 from the inside of the feeding ring 111, falling evenly into the inside of the agglomeration and crushing chamber 1. The photoinitiator particles that meet the mixing size requirements pass through the agglomeration screen 2 and enter the bottom of the agglomeration and crushing chamber 1, while the agglomerates are screened out by the agglomeration screen 2. At the same time, the electric telescopic rod 3 drives the agglomeration screen 2 to move up and down reciprocally, causing the agglomerates to break up. When the electric telescopic rod 3 drives the agglomeration screen 2 to move up and down reciprocally, the agglomeration screen 2 moves downward, and the top hole rod 42 in the top hole device 4 will pass through the filter hole of the agglomeration screen 2, pushing out the photoinitiator raw material blocking the filter hole. At the same time, the agglomerates located on one side of the agglomeration screen 2 are impacted by the top hole rod 42 and break up.
