A coating structure for producing warm edge spacers

Abstract

This utility model relates to the field of spacer strip production technology, specifically a coating structure for producing warm-edge spacers. It includes a housing with a heating mechanism inside. The heating mechanism comprises a preheating component, a conveying component, and a heating element. The heating element includes a hanger fixedly installed on the upper surface of the housing. A second electric push rod is fixedly embedded on one side of the hanger, and a second heating tube is fixedly installed at one end of the second electric push rod via a bracket. In this utility model, the spacer strip is preheated by a heating roller to increase the temperature of the spacer strip when in contact with the hot adhesive, preventing the adhesive from cooling down due to contact with a low-temperature spacer strip, which would weaken adhesion. Simultaneously, the temperature of the coated adhesive is monitored. If the adhesive temperature does not meet the process requirements, it is reheated to improve the adhesive strength and maintain adhesion.

Description

Technical Field

[0001] This utility model relates to the field of spacer production technology, specifically to a coating structure for producing warm-edge spacers. Background Technology

[0002] Warm edge spacer strips are elastic materials used in the production of insulated glass units to seal the space between two panes of glass by bonding them together. They can fill with desiccant, isolate the original glass panes, and provide structural support. Applied between double glazing panes, they provide thermal insulation and noise reduction, and are widely used in decoration, interior insulation, and other fields. During production, warm edge spacer strips require the use of an adhesive applicator to apply adhesive.

[0003] When applying adhesive to existing warm-changing spacers, the adhesive is usually heated and then applied to one side of the spacer. Since the spacer itself is at a low temperature, the temperature of the adhesive will drop after contact with the hot adhesive. When the temperature of the adhesive is lower than the process requirements, its adhesion performance in that area will weaken, resulting in insufficient bonding strength between the adhesive and the spacer. It is not convenient to reheat the adhesive in areas where the temperature is too low. Utility Model Content

[0004] The purpose of this invention is to provide a coating structure for producing warm edge spacers, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A gluing structure for producing warm edge spacers includes a chamber, an adhesive feeding mechanism at the upper end of the chamber, an adhesive gun head mounted inside the chamber via an electric push rod, and a heating mechanism inside the chamber, the heating mechanism comprising:

[0007] The preheating component is located inside the chamber.

[0008] The conveying components are located inside the chamber.

[0009] A heating assembly is installed inside the chamber. The heating assembly includes a hanger fixedly installed on the upper surface inside the chamber. A second electric push rod is fixedly embedded on one side of the hanger. A second heating tube is fixedly installed at one end of the second electric push rod through a bracket.

[0010] Furthermore, an infrared temperature sensor is fixedly installed on one side surface of the hanger via a bracket.

[0011] Furthermore, the conveying assembly includes:

[0012] The fixed frame is fixedly installed on the lower surface inside the silo body;

[0013] A two-way screw is rotatably connected inside the fixed frame;

[0014] Two threaded sleeves are symmetrically screwed onto the outside of the bidirectional screw and slide against the fixed frame;

[0015] Two No. 3 U-shaped brackets are symmetrically fixedly installed on the upper surface of the two threaded sleeves.

[0016] Preferably, a No. 1 motor capable of driving a bidirectional screw to rotate is fixedly installed at one end of the fixed frame, a conveying roller is rotatably connected inside the No. 3 U-shaped frame, and a No. 2 motor capable of driving the conveying roller to rotate is fixedly installed at the upper end of the No. 3 U-shaped frame.

[0017] Furthermore, the preheating component includes:

[0018] The No. 1 U-shaped frame is fixedly installed on the lower surface inside the warehouse.

[0019] The second U-shaped frame is movable above the first U-shaped frame;

[0020] Multiple hollow rotating rollers are rotatably connected inside the No. 1 and No. 2 U-shaped frames, respectively.

[0021] Preferably, a sliding rod is symmetrically fixedly installed on one side surface of the second U-shaped frame. The sliding rod slides through the upper surface of the silo body, and a spring is movably sleeved on the outside of the sliding rod between the second U-shaped frame and the silo body.

[0022] Preferably, a heating tube is fixedly installed inside the hollow roller, and conductive slip rings are fixedly installed on one end surface of both the first and second U-shaped frames, with one end of the hollow roller fixedly penetrating the inner ring of the conductive slip ring at the corresponding position.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] 1. The operation of motor 1 causes two threaded sleeves to drive two conveyor rollers to move towards each other, enabling the two conveyor rollers to clamp spacer strips of different widths. Motor 2 drives the conveyor rollers to rotate, pushing the spacer strips between the two conveyor rollers to move. The lower hollow roller supports the spacer strips, while the upper hollow roller abuts against the spacer strips from above, ensuring that the spacer strips are conveyed on the same plane, thus improving the stability of the spacer strips when applying adhesive.

[0025] 2. An infrared temperature sensor detects the temperature of the adhesive after application. When the adhesive temperature does not reach the set value, the second electric push rod extends, causing the second heating tube, which is in a heated state, to move down and heat the adhesive. By detecting the temperature of the applied adhesive, the adhesive is reheated when the temperature does not meet the process requirements, thereby improving the adhesive strength and maintaining the adhesion of the adhesive.

[0026] 3. When the spacer strip passes over the surface of the hollow roller, the No. 1 heating tube works to heat the hollow roller, so that the heat is transferred to the spacer strip to preheat the spacer strip and increase the temperature of the spacer strip when it comes into contact with the hot adhesive, so as to prevent the hot adhesive strip from coming into contact with the low temperature spacer strip, which would cause the adhesive temperature to drop and weaken the adhesion.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figure 1-4In this embodiment of the utility model, a glue-applying structure for producing warm-edge spacers includes a hopper 1. A glue-feeding mechanism 101 is provided at the upper end of the hopper 1. A glue-applying gun head 103 is installed inside the hopper 1 via a first electric push rod 102. The glue-feeding mechanism 101 uses compressed air to deliver the glue to the glue-applying gun head 103. The glue-applying gun head 103 heats the glue and moves up and down under the drive of the first electric push rod 102 to apply glue to the spacers. A heating mechanism is provided inside the hopper 1. The heating mechanism includes: a preheating component 2 disposed inside the hopper 1, a conveying component 3 disposed inside the hopper 1, and a heating component 4 disposed inside the hopper 1. The heating component 4 includes a hanger 401 fixedly installed on the upper surface inside the hopper 1. A second electric push rod 402 is fixedly embedded on one side surface of the hanger 401. A second heating tube 403 is fixedly installed at one end of the second electric push rod 402 via a bracket.

[0034] Specifically, the spacer passes between the preheating component 2 and the conveying component 3. The conveying component 3 moves the spacer, the preheating component 2 preheats the spacer to increase its contact temperature with the adhesive, and the heating component 4 detects the temperature of the adhesive. If the temperature is insufficient, the adhesive is heated a second time.

[0035] Example 1

[0036] like Figure 1 and Figure 3 As shown, in this embodiment, the conveying assembly 3 includes: a fixed frame 301 fixedly installed on the lower surface inside the chamber 1; a bidirectional screw 302 rotatably connected to the inside of the fixed frame 301; two threaded sleeves 303 symmetrically screwed onto the outside of the bidirectional screw 302 and slidably attached to the fixed frame 301; two U-shaped frames 305 symmetrically fixedly installed on the upper surfaces of the two threaded sleeves 303; a first motor 304 capable of driving the bidirectional screw 302 to rotate is fixedly installed at one end of the fixed frame 301; a conveying roller 306 is rotatably connected inside the U-shaped frame 305; and a second motor 307 capable of driving the conveying roller 306 to rotate is fixedly installed at the upper end of the U-shaped frame 305.

[0037] In this embodiment, motor 304 operates, driving bidirectional screw 302 to rotate. Through its screw-on connection with threaded sleeve 303, and under the sliding limit of threaded sleeve 303 and fixed frame 301, the two threaded sleeves 303 drive the two conveying rollers 306 to move towards each other, so that the two conveying rollers 306 can clamp spacers of different widths. Motor 307 operates, driving conveying roller 306 to rotate, pushing the spacers between the two conveying rollers 306 to move.

[0038] like Figure 4 As shown, in this embodiment, an infrared temperature sensor 405 is fixedly mounted on one side surface of the hanger 401 by a bracket.

[0039] In practice, after the adhesive is applied, the infrared temperature sensor 405 detects the temperature of the adhesive. If the temperature of the adhesive does not reach the set value, the second electric push rod 402 extends, causing the second heating tube 403, which is in a heated state, to move down and heat the adhesive. By detecting the temperature of the applied adhesive, if the temperature of the adhesive does not meet the process requirements, the adhesive is heated a second time to improve the bonding strength of the adhesive and maintain its adhesion.

[0040] Example 2

[0041] Based on Example 1, in order to compensate for the problem that low-temperature spacers can easily lead to a decrease in adhesive temperature and thus weakened adhesion.

[0042] like Figure 2 As shown, in this embodiment, the preheating component 2 includes: a first U-shaped frame 201 fixedly installed on the lower surface of the inner chamber 1, a second U-shaped frame 202 movably disposed above the first U-shaped frame 201, and multiple hollow rollers 205 rotatably connected to the inside of the first U-shaped frame 201 and the second U-shaped frame 202 respectively; a sliding rod 203 is symmetrically fixedly installed on one side surface of the second U-shaped frame 202, the sliding rod 203 slides through the upper surface of the chamber 1, and a spring 204 is movably sleeved on the outside of the sliding rod 203 between the second U-shaped frame 202 and the chamber 1. The elastic force of the spring 204 pushes the second U-shaped frame 202 with a downward force, so that the two symmetrical hollow rollers 205 can fit against the spacer strip.

[0043] In practice, the lower hollow roller 205 supports the spacer strip, while the upper hollow roller 205 presses against the spacer strip from above, so that the spacer strip is conveyed on the same plane, improving the stability of the spacer strip when applying glue.

[0044] like Figure 2 As shown, in this embodiment, a first heating tube 206 is fixedly installed inside the hollow rotating roller 205. Conductive slip rings 207 are fixedly installed on one end surface of the first U-shaped frame 201 and the second U-shaped frame 202. One end of the hollow rotating roller 205 is fixedly inserted through the inner ring of the conductive slip ring 207 at the corresponding position. The conductive slip ring 207 enables electricity to be transmitted to the rotating first heating tube 206.

[0045] In practice, when the spacer strip passes over the surface of the hollow roller 205, the first heating tube 206 operates to heat the hollow roller 205, so that the heat is transferred to the spacer strip to preheat the spacer strip and increase the temperature of the spacer strip when it comes into contact with the hot adhesive, so as to prevent the adhesion from weakening due to the drop in adhesive temperature caused by the hot adhesive coming into contact with the low-temperature spacer strip.

[0046] In this utility model, in order to facilitate the operator's control of the utility model, a PLC controller can be set up. The first heating tube 206, the first motor 304, the second motor 307, the second electric push rod 402, the second heating tube 403 and the infrared temperature sensor 405 are all electrically connected to the PLC controller. The PLC controller is existing technology and will not be described in detail here.

[0047] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0048] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
