The viscosity of the resin material is closely related to the performance of the final product. Therefore, it is necessary to detect the viscosity of the resin material when using or processing it.

A sticky block is arranged at the end, a tension sensor is arranged inside the base, and a container is arranged on the top of the tension sensor. The present invention drives the wire coil to pull the sticky block outward from the resin material in the container through a small motor. During the pulling process, the tension sensor feels that the container is pulled upward and displays the value on the digital display screen on the surface of the base. The user can know the viscosity of the material by observing the value displayed on the digital display screen. The practical structure is simple and easy to operate. The tension sensor is used to sense the upward tension received by the container and display it outward through the digital display screen, so as to avoid errors caused by the user's naked eye observation that affects the subsequent processing of the resin material.

[0003] The problem with the prior art is that due to the certain weight of the container and the resin material inside, and the friction between the container and the support frame, the entire container and all the resin material are pulled upward only by a small part of the resin material adhered by the sticky block, and the measurement result is less accurate. In addition, due to the characteristics of the resin material, it takes a long time to clean the sticky block after the measurement. Summary of the invention

DETAILED DESCRIPTION

[0029] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0030] The structure of the present invention is described in detail below in conjunction with the accompanying drawings.

[0031] Example 1

[0032] like Figures 1 to 5 As shown, an embodiment of the present invention provides a viscosity detection device for a resin material, comprising a detection cylinder 1, a plurality of legs 11 are fixedly connected to the bottom of the detection cylinder 1, a lifting mechanism 2 is connected to the legs 11, a detection mechanism 3 is rotatably connected to the middle of the lifting mechanism 2, the detection mechanism 3 comprises a mounting cylinder 31 and a tension sensor 34, the tension sensor 34 is fixedly installed in the mounting cylinder 31, an adhesive plate 35 is fixedly connected to the output end of the tension sensor 34, and a scraper 4 is movably arranged under the adhesive plate 35.

[0033] Specifically, the detection cylinder 1 is used to store the resin material to be detected, and the lifting mechanism 2 is used to drive the detection mechanism 3 to move up and down. The detection mechanism 3 moves downward to the inside of the detection cylinder 1, so that the resin material is adhered to the lower surface of the adhesive plate 35, and then moves upward. The viscosity of the resin material causes the adhesive plate 35 to generate a downward pulling force, and the pulling force is detected by the tension sensor 34 to obtain the viscosity of the resin material. The scraper 4 is used to scrape off most of the material on the lower surface of the adhesive plate 35 to reduce the difficulty of subsequent cleaning.

[0034] Furthermore, the lifting mechanism 2 includes a lifting plate 21, a screw 22 and a plurality of guide rods 23. The bottom of the screw 22 is rotatably connected to the support leg 11, and the bottom of the guide rod 23 is fixedly connected to the support leg 11. A screw sleeve 221 is threadedly sleeved on the screw 22, and a sliding sleeve 231 is slidably sleeved on the guide rod 23. The screw sleeve 221 and the sliding sleeve 231 are fixedly connected in the lifting plate 21.

[0035] Specifically, a plurality of legs 11 are circumferentially arranged at the bottom of the detection tube 1 to support the detection tube 1. A screw 22 and a plurality of guide rods 23 are circumferentially installed on the legs 11 to support and guide the lifting plate 21. When lifting and lowering, the screw sleeve 221 is driven to move upward or downward accordingly by rotating the screw 22, thereby driving the lifting plate 21 to move synchronously. The sliding cooperation between the sleeve 231 and the guide rod 23 can ensure the stability of the lifting plate 21, thereby preventing the sticking plate 35 from tilting, and ensuring that the resin material is evenly adhered to the lower surface of the sticking plate 35.

[0036] Furthermore, a swivel 33 is fixedly sleeved on the upper end of the installation cylinder 31 , and the swivel 33 is rotatably connected to the middle of the lifting plate 21 . A hand wheel 32 is provided on the top of the installation cylinder 31 , and a retaining ring 36 is fixedly connected to the upper surface of the adhesive plate 35 .

[0037] Furthermore, a sealing sleeve 13 is provided through the bottom of the detection tube 1, a support rod 41 is slidably connected inside the sealing sleeve 13, a limiting block 42 is fixedly connected to the bottom of the support rod 41, and a limiting seat 12 is fixedly connected to the lower surface of the detection tube 1 and located on both sides of the support rod 41, the limiting block 42 is clamped with the limiting seat 12, and the scraper 4 is fixedly connected to the top of the support rod 41.

[0038] Specifically, the mounting tube 31 is used to install the tension sensor 34, the swivel 33 is used to rotate the mounting tube 31 and connect it to the middle part of the lifting plate 21, the handwheel 32 can conveniently manually rotate the mounting tube 31, the retaining ring 36 can prevent the resin material from being immersed in the connection between the adhesive plate 35 and the tension sensor 34 when it contacts the adhesive plate 35, the sealing sleeve 13 is used to ensure the sealing of the bottom of the detection tube 1 to prevent the resin material from leaking, the limit seat 12 is used to limit the limit block 42, so that the position of the scraper 4 is fixed, and the blades of the scraper 4 are inclined and made of a material that is not easy to stick.

[0039] After the measurement is completed, push the support rod 41 upward until the scraper 4 is in close contact with the lower surface of the adhesive plate 35, and then rotate the limit block 42 so that its two ends are inserted into the limit seat 12. There is friction between the inner wall of the limit seat 12 and the limit block 42. When the limit block 42 is in close contact with the limit seat 12, the installation cylinder 31 and the adhesive plate 35 are driven to rotate by manually turning the handwheel 32, so that the adhesive plate 35 rotates relative to the scraper 4, and the resin material adhered to the surface of the adhesive plate 35 slides along the surface of the scraper 4, thereby removing most of the resin material on the adhesive plate 35, greatly reducing the difficulty of subsequent cleaning and achieving quick cleaning.

[0040] Example 2

[0041] When the resin material is injected into the detection cylinder 1, it is difficult for the resin material to be evenly distributed at the bottom of the detection cylinder 1. In order to solve this problem, the following settings are made on the basis of Example 1:

[0042] See also Figure 1-Figure 8 A first receiving groove 51 is provided at the center of the lower surface of the adhesive plate 35, and a pawl 52 is installed in the first receiving groove 51; a second receiving groove 53 is provided at the upper end of the support rod 41, and an elastic member 54 (such as a spring) is provided in the second receiving groove 53, and a lifting column 55 is slidably connected in the second receiving groove 53, and the lower end of the lifting column 55 is fixedly connected to the elastic member 54; the upper end of the lifting column 55 is connected to a ratchet 56 that can cooperate with the pawl 52.

[0043] Through this arrangement, when the resin material is injected into the detection cylinder 1, the adhesive plate 35 is driven to rotate through the installation cylinder 31, and the adhesive plate 35 drives the support rod 41 to rotate through the structure of the pawl 52 and the ratchet 56, and the support rod 41 drives the support rod 41 to rotate, thereby flattening the resin material at the bottom of the detection cylinder 1, and the resin material will not stick to the adhesive plate 35.

[0044] Furthermore, since the lifting column 55 can rise, when the resin material is flattened, there is a gap between the adhesive plate 35 and the resin material, and the resin material will not stick to the adhesive plate 35. Furthermore, the lifting column 55 can fall, and it will not hinder the adhesive plate 35 from falling and contacting the resin material.

[0045] When the scraper 4 is needed to scrape off the resin material sticking to the lower surface of the adhesive plate 35, the limit block 42 is first inserted into 12, and then the adhesive plate 35 is reversed. At this time, the support rod 41 and the scraper 4 will not rotate, while the adhesive plate 35 rotates, so that the resin material sticking to the lower surface of the adhesive plate 35 can be scraped off.

[0046] Example 2

[0047] A method for detecting the viscosity of a resin material, using the device for detecting the viscosity of a resin material, comprises the following steps:

[0048] Step 1: Rotate the screw 22 to drive the lifting plate 21, the tension sensor 34 and the adhesive plate 35 to move downward, so that the lower surface of the adhesive plate 35 is immersed in the resin material and evenly adhered to the resin material;

[0049] Step 2: The tension sensor 34 is driven to move upward by the screw 22, and the viscosity of the resin material causes the adhesive plate 35 to generate a downward pulling force. The tension sensor 34 detects the tension value to obtain the viscosity of the resin material;

[0050] Step 3: After the inspection is completed, move the limit block 42 upward, and then rotate the limit block 42 to clamp it in the limit seat 12, so that the scraper 4 is close to the lower surface of the adhesive plate 35, and manually rotate the hand wheel 32 to rotate the adhesive plate 35 relative to the scraper 4. During the rotation process, the resin material adhered to the adhesive plate 35 slides along the surface of the scraper 4, thereby cleaning the adhesive plate 35.

[0051] Working principle of the present invention:

[0052] When in use, the screw 22 is rotated to drive the lifting plate 21, the tension sensor 34 and the sticking plate 35 to move downward, so that the lower surface of the sticking plate 35 is immersed in the resin material. After the resin material is evenly adhered, the tension sensor 34 is driven to move upward by the screw 22. The viscosity of the resin material causes the sticking plate 35 to generate a downward pulling force. The tension sensor 34 detects the tension value to obtain the viscosity of the resin material. After the detection is completed, the limit block 42 is moved upward, and then the limit block 42 is rotated to the limit seat 12 and clamped, so that the scraper 4 is close to the lower surface of the sticking plate 35, and the hand wheel 32 is manually rotated to rotate the sticking plate 35 relative to the scraper 4. During the rotation process, the resin material adhered to the sticking plate 35 slides along the surface of the scraper 4, so that the sticking plate 35 is cleaned.

[0053] To sum up: this viscosity detection device for resin materials drives the sticky plate 35 to move downward through the lifting mechanism 2, so that the lower surface of the sticky plate 35 adheres to the resin material, and then moves upward. The viscosity of the resin material causes the sticky plate 35 to generate a downward pulling force, and the pulling force is detected by the tension sensor 34 to obtain the viscosity of the resin material. By making the scraper 4 close to the lower surface of the sticky plate 35, the sticky plate 35 is rotated to make the resin material slide along the surface of the scraper 4, so that most of the resin material on the sticky plate 35 can be removed, which greatly reduces the difficulty of subsequent cleaning and achieves quick cleaning.
