Description

Technical Field

[0001] This invention belongs to the field of chemistry, and in particular relates to a quantitative extrusion device. Background Technology

[0002] Extrusion devices are mainly divided into hand-push extruders, pneumatic extruders, and high-pressure pump extruders. However, a major drawback of current extrusion devices is their inability to accurately control the extruded material. Taking a hand-push extruder as an example, the extruded material is controlled by the slider's movement distance, which is entirely manual. However, accurate manual control is often difficult, resulting in inaccurate extrusion volume. The current mainstream solution is to use a measuring container to collect the material. While this can alleviate the problem of uncontrollable extrusion volume to some extent, manual operation is also prone to errors, easily leading to over-extrusion or under-extrusion. Summary of the Invention

[0003] In view of this, the present invention aims to overcome the defects in the prior art and propose a quantitative extrusion device.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A quantitative extrusion device includes a base, a support frame is provided on the base, an extrusion barrel is provided on the support frame, and an extrusion cover is provided on the extrusion barrel.

[0006] The extrusion cover is provided with a pressure rod, one end of which passes through the extrusion cover and is placed inside the extrusion barrel. The end of the pressure rod is provided with a pressure plate, and several prompting mechanisms are provided on the side wall of the extrusion barrel.

[0007] Furthermore, the side wall of the extrusion barrel is provided with a plurality of receiving holes, and a prompting mechanism is provided in the receiving holes.

[0008] Furthermore, an inner limiting plate is provided on the inner side of the receiving hole, and an outer limiting plate is provided on the outer side of the receiving hole. The inner and outer limiting plates effectively limit the movement of the prompting mechanism.

[0009] Furthermore, the prompting mechanism includes an inner extrusion block, an extrusion spring, an extrusion ball, a clamping assembly, and a prompting frame. The extrusion block is placed in the receiving hole, and an extrusion plate is provided at one end of the extrusion block. The extrusion spring is located between the inner limiting plate and the extrusion plate. One end of the extrusion ball is connected to the extrusion plate. The clamping assembly is located between the extrusion ball and the prompting frame. A prompting plate is provided at one end of the prompting frame, and the prompting plate is located outside the outer limiting plate. The prompting mechanism is evenly arranged from top to bottom, and the parameters of the prompting mechanism at different heights can be set according to the density, mass, etc. of the material, thereby realizing quantitative material discharge.

[0010] Furthermore, the extrusion block is provided with an extrusion head, and the extrusion head and the extrusion plate are respectively located on both sides of the extrusion block; the clamping assembly includes two clamping blocks with the same structure and arranged opposite each other, the outer sides of the clamping blocks are rotatably connected to the extrusion barrel through corresponding rotating shafts, and the inner sides of the clamping blocks are provided with clamping grooves, which cooperate with the extrusion balls; one end of the indicator frame is provided with a top block, which cooperates with the clamping assembly, and the other end of the indicator frame is provided with a plurality of limiting balls, and the inner side of the outer limiting plate is provided with a plurality of limiting grooves, which cooperate with the limiting balls. In its initial state, the extrusion head extends beyond the inner limiting plate. As the pressure plate descends, it squeezes the sidewall of the extrusion head, which then enters the receiving hole. The extrusion plate moves the extrusion ball outward, placing it in the clamping groove. At this point, one end of the clamping block rotates inward, and the other end rotates outward, pushing the top block outward. This causes the limiting ball of the indicator frame to enter the limiting groove of the outer limiting plate. The limiting ball's position is now fixed, and the indicator plate of the indicator frame protrudes outward, alerting the operator that a certain volume or mass of material has been extruded. After extrusion is complete, the pressure rod can be raised to its initial position, and then the indicator plate can be pushed inward, disengaging the limiting ball from the limiting groove. The clamping block then rotates, disengaging the extrusion ball from the clamping block, and the extrusion spring returns to its initial state.

[0011] Furthermore, a conical pressure block is provided at the bottom of the pressure plate, and an extrusion platform is provided at the bottom inner side of the extrusion barrel. The structure of the extrusion platform cooperates with the pressure block. The longitudinal section of the extrusion platform is a right-angled triangle structure, and the inclination angle is matched with the pressure block. The conical structure of the pressure block facilitates the operator to extrude the material, making the operation more labor-saving and allowing the material to be distributed more evenly within the extrusion barrel.

[0012] Furthermore, the support frame has an insertion hole, and a limiting seat is provided on the outside of the insertion hole. The bottom of the extrusion barrel has a discharge port, which is placed inside the insertion hole. The limiting seat limits the extrusion barrel to prevent the discharge port from shaking inside the insertion hole and to reduce damage to the discharge port.

[0013] Furthermore, a collection bucket is provided on the base, and the collection bucket is located below the discharge port. The extruded material directly enters the collection bucket.

[0014] Compared with the prior art, this utility model has the following advantages:

[0015] The quantitative extrusion device of this invention has several prompting mechanisms on the extrusion barrel. By pressing the pressure plate down to a certain height, the extrusion amount of material is determined, saving manpower and time and improving production and testing efficiency.

[0025] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] like Figure 1-3 As shown, a quantitative extrusion device includes a base 1, a support frame 2 on the base 1, an extrusion barrel 4 on the support frame 2, an extrusion cover 41 on the extrusion barrel 4, a pressure rod 42 on the extrusion cover 41, one end of the pressure rod 42 passing through the extrusion cover 41 and placed inside the extrusion barrel 4, a pressure plate 43 at the end of the pressure rod 42, and several prompting mechanisms 46 on the side wall of the extrusion barrel 4.

[0027] The extrusion barrel 4 has several receiving holes 47 on its side wall, and a prompting mechanism 46 is installed inside each receiving hole 47. An inner limiting plate 471 is provided inside each receiving hole 47, and an outer limiting plate 472 is provided outside each receiving hole 47. The inner limiting plate 471 and the outer limiting plate 472 effectively limit the prompting mechanism 46.

[0028] The prompting mechanism 46 includes an inner squeezing block 461431, a squeezing spring 462, a squeezing ball 463, a clamping assembly, and a prompting frame 466. The squeezing block 431 is placed in the receiving hole 47, and a squeezing plate 461243 is provided at one end of the squeezing block 431. The squeezing spring 462 is located between the inner limiting plate 471 and the squeezing plate 461243. One end of the squeezing ball 463 is connected to the squeezing plate 461243. The clamping assembly is located between the squeezing ball 463 and the prompting frame 466. A prompting plate 4663 is provided at one end of the prompting frame 466, and the prompting plate 4663 is located outside the outer limiting plate 472. The prompting mechanism 46 is evenly arranged from top to bottom, and the parameters of the prompting mechanism 46 at different heights can be set according to the density, mass, etc. of the material, thereby realizing quantitative material discharge.

[0029] The extrusion block 431 is provided with an extrusion head 4611, which is located on both sides of the extrusion block 431, along with the extrusion plate 461243. The clamping assembly includes two clamping blocks 464 with identical structures, arranged opposite each other. The outer sides of the clamping blocks 464 are rotatably connected to the extrusion barrel 4 via corresponding rotating shafts 465. The inner sides of the clamping blocks 464 are provided with clamping grooves 4641, which cooperate with the extrusion ball 463. One end of the prompting frame 466 is provided with a top block 4661, which cooperates with the clamping assembly. The other end of the prompting frame 466 is provided with a plurality of limiting balls 4662. The inner side of the outer limiting plate 472 is provided with a plurality of limiting grooves 4721, which cooperate with the limiting balls 4662.

[0030] The bottom of the pressure plate 43 is provided with a conical pressure block 431, and the bottom inner side of the extrusion barrel 4 is provided with an extrusion platform 45, the structure of which cooperates with the pressure block 431. The longitudinal section of the extrusion platform 45 is a right-angled triangle, and its inclination angle is matched with that of the pressure block 431. The conical structure of the pressure block 431 facilitates the operator to extrude the material, making the operation more labor-saving and allowing the material to be distributed more evenly within the extrusion barrel 4.

[0031] The support frame 2 has an insertion hole 22, and a limiting seat 21 is provided on the outside of the insertion hole 22. The bottom of the extrusion barrel 4 has a discharge port 44, which is placed inside the insertion hole 22. The limiting seat 21 limits the extrusion barrel 4 to prevent the discharge port 44 from shaking inside the insertion hole 22, thereby reducing damage to the discharge port 44.

[0032] A collection bucket 3 is provided on the base 1, and the collection bucket 3 is located below the discharge port 44. The extruded material directly enters the collection bucket 3.

[0033] Implementation process:

[0034] Before extrusion, the mass or volume of the material to be extruded to different heights of the prompting mechanism 46 is calculated based on the material parameters. Then, the material is added into the extrusion barrel 4, the extrusion cover 41 is covered by the extrusion barrel 4, and the pressure rod 42 is driven to extrude the material. When the pressure plate 43 reaches the first prompting mechanism 46, the formal extrusion begins. After the pressure plate 43 reaches a certain height of the prompting mechanism 46, the extrusion amount is calculated.

[0035] In its original state, the extrusion head 4611 extends outward from the inner limiting plate 471. During the downward movement of the pressure plate 43, the extrusion head 4611 is squeezed against the side wall. After the extrusion head 4611 is in place, it enters the receiving hole 47. The extrusion plate 461243 drives the extrusion ball 463 to move outward, thereby placing the extrusion ball 463 in the clamping groove 4641. At this time, one end of the clamping block 464 rotates inward and the other end rotates outward, thereby pushing the top block 4661 to move outward, so that the limiting ball 4662 of the indicator frame 466 enters the limiting groove 4721 of the outer limiting plate 472. At this time, the position of the limiting ball 4662 is fixed, and the indicator plate 4663 of the indicator frame 466 protrudes outward to indicate to the operator that a certain volume or mass of material has been extruded. After the material is discharged, the pressure bar 42 can be raised to the initial position, and then the indicator plate 4663 can be pushed inward to disengage the limiting ball 4662 from the limiting groove 4721. Then the clamping block 464 can be rotated, the extrusion ball 463 can be disengaged from the clamping block 464, and the extrusion spring can be reset to the initial state.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
