Description

Technical Field

[0001] The present invention relates to a processing technology for separating epoxy resin glue from a substrate, and in particular to a processing technology for separating epoxy resin glue from a substrate applied in the technical field related to building detection. Background Art

[0002] When testing the strength of building waterproof coatings, plaster mortar, carbon fiber, thermal insulation panels, etc., the end of the pulling head is generally coated with epoxy resin and then bonded to the sample to be tested. After the glue dries, a tensile device is used to apply a uniform axial load to the pulling head until the substrate is damaged. The strength of the substrate is then tested in sequence. After the test is completed, the epoxy resin glue needs to be removed in order to reuse the pulling head. For example, the specification of Chinese patent CN205808898U discloses a device for bonding, pulling, and fixing a pulling head for thermal insulation panels.

[0003] Epoxy resin can generally be separated in a variety of ways, such as baking it on an electric stove. However, this produces a large amount of toxic fumes, and due to the size of the electric stove, only 3-5 pulling heads can be softened at a time, resulting in a very unsatisfactory separation effect. For example, the specification of Chinese patent CN105946251B discloses a drainage ditch production process, in which the epoxy resin is softened by baking. There is also a method of softening and separating the epoxy resin glue by burning, but this also produces a large amount of toxic and harmful gases, which affects the environment and harms human health. Summary of the Invention

[0004] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that the existing separation method of baking or burning will produce harmful gases, which will have adverse effects on the environment and the health of workers.

[0005] To solve the above problems, the present invention provides a process for separating epoxy resin adhesive from a substrate, comprising the following steps:

[0006] S1. First, sufficient water is introduced into the steam softening device, and then the drawing head with epoxy resin is placed into multiple dynamic trays in the steam softening device;

[0007] S2. Activate the heating unit to heat the water to generate steam. The steam temperature is maintained at 100-110°C. The steam spreads upward and, under the action of the air guide strips, quickly diffuses between the multiple dynamic trays. The steam fully contacts the multiple drawing heads with epoxy resin in the dynamic trays, thereby softening them.

[0008] S3. During the softening process, the dynamic tray is controlled to continuously move back and forth in a small range in the longitudinal direction, thereby keeping the drawing head in a dynamic state;

[0009] S4. Maintain the softening process for 15-30 minutes. After softening, remove the pulling head with epoxy resin and scrape it off with a scraper within 20 minutes after removal.

[0010] The steam softening device includes an equipment body, which is equipped with a transparent sealing door. A steam water tank is provided at the bottom of the equipment body, and a mesh plate is placed at the upper end of the steam water tank. The left and right ends of the equipment body are fixedly connected with a water inlet pipe and a drain pipe, and both are communicated with the steam water tank. A heating unit is installed at the bottom of the steam water tank, and a liquid level sensor is installed inside the steam water tank. A plurality of corresponding lining strips are fixedly connected to the left and right inner walls of the equipment body, and a dynamic tray is placed above the two opposite lining strips. A plurality of temperature sensors are installed inside the equipment body, and the plurality of temperature sensors are respectively located above the plurality of dynamic trays. Among the two opposite lining strips, a single pendulum unit is also provided below one of the lining strips, and a limited long groove is provided below the other lining strip. The limited long groove is excavated on the inner wall of the equipment body. Two air guide strips are fixedly connected to the middle of the rear inner wall of the equipment body. A plurality of evenly distributed fixed air guide holes are excavated at the front end of the air guide strip. The lower end of the air guide strip passes through the mesh plate and extends into the steam water tank.

[0011] In the above-mentioned treatment process for separating the epoxy resin glue from the substrate, steam softening is used instead of the baking and burning in the prior art. During softening, the pulling head with epoxy resin is always in motion, so that it can fully contact with the steam, thereby achieving full and uniform softening of the pulling heads with epoxy resin in batches. Compared with the prior art, this effectively reduces the generation of harmful gases and effectively speeds up the softening efficiency, thereby effectively speeding up the separation efficiency.

[0012] As a further improvement of the present application, gaps are formed between the front and rear ends of the multiple dynamic trays and the rear inner wall of the equipment body and the transparent sealed door respectively. The lower end of the air guide strip is located above the water level in the steam tank, and the air guide strip is connected to the steam tank.

[0013] As a further improvement of the present application, the dynamic pallet includes a support plate resting on top of two relative lining strips, with a plurality of evenly distributed rectangular long holes being bored on the support plate, and a translation pocket being fixedly connected to the lower mouth of the rectangular long hole, and the translation pocket including a load-bearing pocket body and a guide rod placed on the load-bearing pocket body, one end of the guide rod being fixedly connected to the single pendulum unit, and the other end of the guide rod extending into the limiting long groove, the mouth size of the rectangular long hole being larger than the size of the drawing head, and the load-bearing pocket body being made of a flexible material with high breathability.

[0014] As a further improvement of the present application, the simple pendulum unit includes two electromagnetic plates fixedly connected to the inner wall of the device body and a translational magnetic strip located between the two electromagnetic plates. The translational magnetic strip is slidingly connected to the inner wall of the device body. The connection point between the guide rod and the simple pendulum unit is located on the translational magnetic strip. When energized, a magnetic attraction force is generated between the electromagnetic plate and the translational magnetic strip. The maximum distance between the translational magnetic strip and the electromagnetic plate is not greater than the width of the rectangular long hole, and not less than half the width of the rectangular long hole.

[0015] As a further improvement of the present application, two side strips symmetrical about the rectangular long hole are fixedly connected to the lower end of the support plate, and the side strips are flush with the edges of the rectangular long hole.

[0016] As another improvement of the present application, the air guide strip includes a fixed cover shell fixedly connected to the device body, a plurality of dynamic air guide cylinders that are movable through the fixed cover shell toward the end face of the transparent sealing door, an air bleed cylinder that contacts the lowest dynamic air guide cylinder, and a multi-rotating rod connected to the top of the fixed cover shell through an electric rotating shaft. The multi-rotating rod matches the multiple dynamic air guide cylinders, the air bleed cylinders are flush with the bottom of the fixed cover shell, the fixed air guide holes are drilled on the fixed cover shell, and the multiple fixed air guide holes are respectively located on the left and right sides of the dynamic air guide cylinder.

[0017] As another improved supplement to the present application, there are annular clamping limits between the head and tail of two adjacent dynamic gas guide cylinders, as well as between the lowest dynamic gas guide cylinder and the air bleed cylinder. Two electromagnetic limit rings are fixedly connected to the middle of the dynamic gas guide cylinder. The dynamic tray just corresponds to the two electromagnetic limit rings. A magnetic follower plate is provided between the two electromagnetic limit rings. The magnetic follower plate is vertically slidably connected to the surface of the dynamic gas guide cylinder. The multi-rotation rod includes a center rod and a plurality of friction rollers fixedly connected to the outer end of the center rod. The plurality of friction rollers respectively correspond to the middle of the plurality of dynamic gas guide cylinders, and the upper ends of the friction rollers are flush with the ends of the upper electromagnetic limit rings, and the lower ends of the friction rollers are higher than the magnetic follower plates.

[0018] As another improved supplement to the present application, the cross-section of the magnetic follower is fan-shaped, and the curvature of the magnetic follower is 90°-120°. A plurality of evenly distributed dynamic air guide holes are opened in the middle of one end of the dynamic air guide cylinder facing the transparent sealed door, and a plurality of electromagnetic limit rings are respectively located on the side away from each other of the two electromagnetic limit rings. Along the direction from bottom to top, the distribution density of the dynamic air guide holes on the plurality of dynamic air guide cylinders gradually increases.

[0019] In summary, steam softening is used instead of baking and burning in the prior art. During softening, the drawing head with epoxy resin is always in dynamic state, so that it can be in full contact with the steam. At the same time, the temperature of the space above each dynamic tray inside the equipment body can be monitored. The steam can be dynamically guided above the dynamic tray far away from the steam source to cause turbulence of the steam, thereby accelerating the diffusion speed above multiple dynamic trays, thereby effectively reducing the temperature of the space above multiple dynamic trays, and thus achieving sufficient and uniform softening of the drawing heads with epoxy resin in batches. Compared with the prior art, it effectively reduces the generation of harmful gases, and effectively speeds up the softening efficiency, thereby effectively speeding up the separation efficiency.

DETAILED DESCRIPTION

[0034] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0035] The first implementation method:

[0036] Figure 1 A process for separating epoxy resin adhesive from a substrate is shown, comprising the following steps:

[0037] S1. First, sufficient water is introduced into the steam softening device, and then the drawing head with epoxy resin is placed into multiple dynamic trays 5 in the steam softening device;

[0038] S2, such as Figure 2-3 The heating unit is started to heat the water to generate steam. The steam temperature is maintained at 100-110°C. The steam spreads upward and, under the action of the air guide strips 4, quickly diffuses between the multiple dynamic trays 5, so that the steam fully contacts the multiple drawing heads with epoxy resin in the dynamic trays 5, thereby softening them.

[0039] S3. During the softening process, if Figure 6 In the figure, a represents a drawing head with epoxy resin. The dynamic tray 5 is controlled to continuously move back and forth in a small range in the longitudinal direction, thereby keeping the drawing head in a dynamic state. Specifically, the two electromagnetic plates 62 can be controlled to be alternately powered on and off, thereby driving the multiple guide rods 53 to move back and forth in the limiting long groove 104, thereby constantly changing the sides of the triangle formed by the supporting pocket 52, so that the multiple drawing heads with epoxy resin above it are in a dynamic state.

[0040] S4. Maintain the softening process for 15-30 minutes. After softening, remove the pulling head with epoxy resin and scrape it off with a scraper within 20 minutes after removal.

[0041] like Figure 1-3The steam softening device includes an equipment body 1, a transparent sealing door 2 is installed on the equipment body 1, a steam water tank is provided at the bottom of the equipment body 1, a mesh plate 3 is placed on the upper port of the steam water tank, and the left and right ends of the equipment body 1 are fixedly connected with a water inlet pipe 101 and a drain pipe 102, and both are connected to the steam water tank, a heating unit is installed at the bottom of the steam water tank, and a liquid level sensor is installed inside the steam water tank to prevent the steam water tank from being overfilled. At the same time, when the water is low, the liquid level warning can be given to the staff, so that water can be added in time, effectively ensuring the stability of the steam softening process. A plurality of corresponding lining strips 103 are fixedly connected to the left and right inner walls of the equipment body 1. A dynamic tray 5 is placed above the two pairs of lining strips 103. Among the two opposite lining strips 103, a single pendulum unit is also provided below one of the lining strips 103, and a limited long groove 104 is provided below the other lining strip 103. The limited long groove 104 is drilled on the inner wall of the equipment body 1. Two air guide strips 4 are fixedly connected to the middle of the rear inner wall of the equipment body 1. A plurality of evenly distributed fixed air guide holes 401 are drilled at the front end of the air guide strip 4. The lower end of the air guide strip 4 passes through the mesh plate 3 and extends into the steam water tank. The air guide strip 4 can guide part of the steam to diffuse directly above the multiple dynamic trays 5, thereby accelerating the stable and uniform softening of the epoxy resin on the drawing head contained in the multiple dynamic trays 5 above.

[0042] The front and rear ends of the multiple dynamic trays 5 form gaps with the rear inner wall of the equipment body 1 and the transparent sealing door 2 respectively. The lower end of the air guide strip 4 is located above the water level in the steam tank, and the air guide strip 4 is connected to the steam tank, so that the steam overflowing from the screen plate 3 can diffuse upward from both sides of the dynamic tray 5, so that the multiple dynamic trays 5 in the equipment body 1 are all in the steam atmosphere, which facilitates the uniform and stable softening of the epoxy resin.

[0043] like Figure 4-5 The dynamic pallet 5 includes a support plate 51 placed on top of two opposite lining strips 103. A plurality of evenly distributed rectangular long holes are opened on the support plate 51. A translation pocket is fixedly connected to the lower mouth of the rectangular long hole. The translation pocket includes a load-bearing pocket body 52 and a guide rod 53 placed on the load-bearing pocket body 52. ​​One end of the guide rod 53 is fixedly connected to the single pendulum unit, and the other end of the guide rod 53 extends into the limiting long groove 104. The size of the mouth of the rectangular long hole is larger than that of the drawing head. The load-bearing pocket body 52 is made of a flexible material with high air permeability.

[0044] The simple pendulum unit includes two electromagnetic plates 62 fixedly connected to the inner wall of the equipment body 1 and a translational magnetic strip 61 located between the two electromagnetic plates 62. The translational magnetic strip 61 is slidably connected to the inner wall of the equipment body 1. The connection point between the guide rod 53 and the simple pendulum unit is located on the translational magnetic strip 61. After power is turned on, a magnetic attraction force is generated between the electromagnetic plates 62 and the translational magnetic strip 61. The maximum distance between the translational magnetic strip 61 and the electromagnetic plate 62 is not greater than the width of the rectangular long hole and not less than half the width of the rectangular long hole, effectively ensuring that the amplitude of each translation of the dynamic tray 5 will not be greater than the width of the rectangular long hole, so that the pulling head with epoxy resin can be in dynamic state and not prone to local over-extrusion.

[0045] The lower end of the support plate 51 is fixedly connected to two side strips 501 symmetrical about the rectangular long hole. The side strips 501 are also flush with the edges of the rectangular long hole. The support plate 51 can be used as a guardrail to prevent multiple pulling heads from falling along the gap between the two sides of the supporting bag 52 and the support plate 51 during dynamic movement.

[0046] In the above-mentioned treatment process for separating the epoxy resin glue from the substrate, steam softening is used instead of the baking and burning in the prior art. During softening, the pulling head with epoxy resin is always in motion, so that it can fully contact with the steam, thereby achieving full and uniform softening of the pulling heads with epoxy resin in batches. Compared with the prior art, this effectively reduces the generation of harmful gases and effectively speeds up the softening efficiency, thereby effectively speeding up the separation efficiency.

[0047] Second implementation method:

[0048] This embodiment further improves the air guide strip 4 on the basis of the first embodiment, and the rest of the parts remain the same as the first embodiment.

[0049] Figure 7-8As shown, the air guide strip 4 includes a fixed cover shell 41 fixedly connected to the device body 1, a plurality of dynamic air guide cylinders 42 that are movable through the fixed cover shell 41 toward the end face of the transparent sealing door 2, an air bleed cylinder 43 that contacts the lowest dynamic air guide cylinder 42, and a multi-rotation rod 7 connected to the top of the fixed cover shell 41 through an electric rotating shaft. The multi-rotation rod 7 matches the multiple dynamic air guide cylinders 42, and the air bleed cylinder 43 is flush with the bottom of the fixed cover shell 41. The fixed air guide holes 401 are drilled on the fixed cover shell 41, and the multiple fixed air guide holes 401 are respectively located on the left and right sides of the dynamic air guide cylinder 42, between the head and tail of two adjacent dynamic air guide cylinders 42, and the lowest dynamic air guide cylinder 4 2 and the air bleed cylinder 43 are both annularly clamped and limited. Specifically, annular grooves can be dug at the upper ends of the air bleed cylinder 43 and the upper ends of the multiple dynamic air guide cylinders 42, and annular strips matching the annular grooves are fixed at the lower ends of the dynamic air guide cylinders 42 in contact therewith and at the corresponding positions of the fixed cover shell 41 and the uppermost dynamic air guide cylinder 42. At the same time, the dynamic air guide cylinder 42 and the air bleed cylinder 43 and the two adjacent dynamic air guide cylinders 42 are in end-to-end contact, which can make the air bleed cylinder 43 and the multiple dynamic air guide cylinders 42 above form a whole, and the multiple dynamic air guide cylinders 42 can rotate independently, forming turbulence above different dynamic trays 5 according to actual needs, so as to facilitate the rapid diffusion of steam.

[0050] like Figure 9-10 , two electromagnetic limit rings 403 are fixedly connected to the middle of the dynamic air guide cylinder 42, and the dynamic tray 5 just corresponds to the two electromagnetic limit rings 403. A magnetic follower 402 is provided between the two electromagnetic limit rings 403, and the magnetic follower 402 is vertically slidably connected to the surface of the dynamic air guide cylinder 42. The multi-rotation rod 7 includes a central rod 71 and a plurality of friction rollers 72 fixedly connected to the outer end of the central rod 71. The plurality of friction rollers 72 respectively correspond to the middle parts of the plurality of dynamic air guide cylinders 42, and the upper ends of the friction rollers 72 are flush with the ends of the upper electromagnetic limit rings 403, and the lower ends of the friction rollers 72 are higher than the magnetic follower 402. When it is necessary to control the rotation of the dynamic air guide cylinder 42, the upper electromagnetic limit ring 403 can be controlled to be energized, thereby adsorbing the magnetic The magnetic follower plate 402 moves up, and at this time it contacts the corresponding friction roller 72. When the electric shaft controls the center rod 71 to rotate, the friction roller 72 can be driven to rotate. Under the action of friction, the magnetic follower plate 402 and the dynamic air guide cylinder 42 can be rotated as a whole, thereby facilitating the formation of turbulence at the subsequent air guide strip 4. When the temperature of the corresponding space is stable, the electromagnetic limit ring 403 below can be controlled to be energized, and the electromagnetic limit ring 403 above can be powered off. At this time, under the action of gravity and magnetic attraction, the magnetic follower plate 402 can be moved down and misaligned with the friction roller 72, so that it will no longer drive the dynamic air guide cylinder 42 to rotate when it rotates, and then one or more dynamic air guide cylinders 42 can be independently controlled to rotate according to actual needs.

[0051] A plurality of temperature sensors are installed inside the device body 1, and the plurality of temperature sensors are respectively located above the plurality of dynamic trays 5, which can monitor the temperature of the space above each dynamic tray 5 inside the device body 1, and facilitate adjustment of the steam guide mode above the plurality of dynamic trays 5, such as Figure 12 When the temperature above some dynamic trays 5 is low, the corresponding dynamic air guide cylinder 42 can be controlled to rotate back and forth, thereby expanding the amplitude of the steam ejected from the multiple dynamic air guide holes 404, and can cross-collide with the steam ejected from the fixed air guide holes 401, thereby generating turbulence, accelerating the diffusion speed of the steam in the space above the dynamic tray 5, facilitating a faster increase in temperature, and making the temperature of the multiple spaces separated by the dynamic tray 5 in the equipment body 1 tend to be stable, so that the softening of the epoxy resin is more uniform.

[0052] like Figure 11 The cross-section of the magnetic follower 402 is fan-shaped, and the curvature of the magnetic follower 402 is 90°-120°. A plurality of evenly distributed dynamic air guide holes 404 are opened in the middle of one end of the dynamic air guide cylinder 42 facing the transparent sealing door 2, and a plurality of electromagnetic limit rings 403 are respectively located on the side away from each other of the two electromagnetic limit rings 403. Along the direction from bottom to top, the distribution density of the dynamic air guide holes 404 on the plurality of dynamic air guide cylinders 42 gradually increases, so that more steam overflows at one time, which is convenient for compensating for the low temperature due to being away from the steam source.

[0053] In addition, an air pump can be set at the bottom of the air guide strip 4 to facilitate pumping steam into the air guide strip 4 faster, so that the space above the multiple dynamic trays 5 can be exposed to steam faster, making the temperature consistency of the multiple spaces better, and effectively ensuring the softening efficiency of the epoxy resin.

[0054] In summary, steam softening is used instead of baking and burning in the prior art. During softening, the drawing head with epoxy resin is always in dynamic state, so that it can be in full contact with the steam. At the same time, the temperature of the space above each dynamic tray 5 inside the equipment body 1 can be monitored. The steam can be dynamically guided above the dynamic tray 5 far away from the steam source to cause turbulence of the steam, thereby accelerating the diffusion speed above the multiple dynamic trays 5, thereby effectively reducing the temperature of the space above the multiple dynamic trays 5, and thus achieving sufficient and uniform softening of the drawing heads with epoxy resin in batches. Compared with the prior art, it effectively reduces the generation of harmful gases and effectively accelerates the softening efficiency, thereby effectively accelerating the separation efficiency.

[0055] In view of current actual needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of the present invention.
