Description

Technical Field

[0001] The utility model belongs to the technical field related to sealant production, in particular to a sealant quantitative extrusion component. Background Art

[0002] Sealant refers to a sealing material that deforms with the shape of the sealing surface, is not easy to flow, and has a certain degree of adhesion. It is an adhesive used to fill the gap in the configuration to achieve a sealing effect. It has the functions of leak prevention, waterproofing, vibration prevention, sound insulation, and heat insulation. It can be divided into three categories: elastic sealants, liquid sealing gaskets, and sealing putties. However, after the sealant is produced, it is necessary to carry out filling and other operations, and fill it into the corresponding container for packaging and sale. However, due to the adhesion of the sealant, this has certain requirements for quantitative extrusion during the filling operation. For example, the utility model patent with announcement number CN 217919203 U: A quantitative extrusion device for the production of water-based sealants, it still has the following disadvantages in actual use:

[0003] The above patent records that although it has a quantitative extrusion function, it is an integral extrusion, which makes it impossible to quickly add materials after the subsequent extrusion, wasting processing time. Secondly, the integral extrusion is not convenient for controlling the extrusion amount, and it is easy for the sealant to leak after filling and extrusion, resulting in inaccuracy;

[0004] After the sealant is extruded in a certain amount, some residue usually remains on the discharge nozzle, causing it to spill during subsequent replenishment, resulting in unnecessary waste. Utility Model Content

[0005] The utility model aims to provide a sealant quantitative extrusion component, which solves the problems of being unable to quickly refill materials and inconvenient to control the extrusion amount after extrusion is completed, and the problem that there is residue at the discharge nozzle after the sealant is extruded, which is inconvenient for subsequent refilling, by arranging a material storage tank, an extrusion barrel, an extrusion rod, a cylinder, a positioning strip, a sealing sleeve, and a steel ball.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model is a sealant quantitative extrusion assembly, comprising a base, a material storage tank, a cylinder, an extrusion barrel and a positioning strip, wherein the material storage tank is placed on the base, the front side of the material storage tank is fixed with a cylinder, a push plate is fixed on the piston rod at the telescopic end of the cylinder, and two positioning strips are symmetrically fixed on the surface of the material storage tank below the cylinder, and positioning blocks on the same horizontal line are both screwed on the two positioning strips, and a pressure sensor is fixed on a side of the positioning block close to the push plate;

[0008] The front side of the base is fixed with fixed rings distributed at equal intervals, and an extrusion barrel is fixed in each of the fixed rings, an extrusion rod is movably inserted in each of the extrusion barrels, a discharge nozzle is fixed through the bottom end of the extrusion barrel, a traction rope is fixed to the bottom end of the extrusion rod, and a steel ball is fixed at the bottom end of the traction rope passing through the discharge nozzle, and the steel ball is covered with a sealing sleeve.

[0009] Furthermore, an air compressor is fixed on the surface of the storage tank adjacent to the cylinder, and the air outlet pipe of the air compressor is connected to the interior of the storage tank.

[0010] Furthermore, a tank cover is screwed onto the feed inlet at the upper end of the storage tank.

[0011] Furthermore, the inner diameters of the steel ball and the sealing sleeve are greater than the inner diameter of the discharge nozzle, and the height of the extrusion rod is greater than the height of the extrusion barrel.

[0012] Furthermore, a connecting pipe is fixedly passed through the circumference of the extrusion cylinder, and one end of the connecting pipe away from the extrusion cylinder is passed through and fixed to the inside of the material storage tank.

[0013] Furthermore, the positioning bar is provided with positioning holes distributed at equal intervals on a side away from the storage tank, a screw is fixed on a side of the positioning block close to the positioning bar, and the positioning bar is screwed into the positioning hole for positioning by the screw.

[0014] Furthermore, connecting rods matching the number of the extrusion rods are fixed to the bottom surface of the push plate, and the push plate is fixedly connected to the upper ends of the corresponding extrusion rods through the connecting rods.

[0015] The utility model has the following beneficial effects:

[0016] The utility model solves the problems of being unable to quickly refill materials and being inconvenient to control the extrusion amount after extrusion is completed by arranging a material storage tank, an extrusion barrel, an extrusion rod, a cylinder and a positioning strip; the sealant in the material storage tank passively enters the extrusion barrel after being pressurized until the inside of the extrusion barrel is filled, and then the cylinder controls the extrusion rod to move downward to extrude the sealant in the extrusion barrel quantitatively, and the amount of extrusion can be controlled by controlling the extension of the telescopic end of the cylinder through the limitation of the positioning block on the positioning strip, and after quantitative extrusion, the cylinder controls the extrusion rod to move upward until the connecting pipe is connected to the inside of the extrusion barrel, and material is quickly refilled under the pressurized condition in the discharge pipe, so as to quickly carry out the next batch of extrusion operations.

[0017] The utility model solves the problem that residual glue remains at the discharge nozzle after sealant is extruded, which makes subsequent material replenishment inconvenient by arranging an extrusion barrel, an extrusion rod, a sealing sleeve and a steel ball; after extrusion is completed, the extrusion rod moves upward until the steel ball and the sealing sleeve seal the discharge nozzle, and at this time the connecting pipe is just connected to the inside of the extrusion barrel for material replenishment, which not only avoids the residual glue at the discharge nozzle from falling, but also facilitates subsequent material replenishment without spilling.

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0028] See also Figure 1-6 As shown, the utility model is a sealant quantitative extrusion assembly, including a base 1, a storage tank 2, a cylinder 3, an extrusion barrel 4 and a positioning strip 5. The storage tank 2 is placed on the base 1, the cylinder 3 is fixed to the front side of the storage tank 2, a push plate 301 is fixed to the piston rod at the telescopic end of the cylinder 3, and two positioning strips 5 are symmetrically fixed to the surface of the storage tank 2 below the cylinder 3. Positioning blocks 501 on the same horizontal line are both screwed on the two positioning strips 5, and a pressure sensor 502 is fixed to the side of the positioning block 501 close to the push plate 301;

[0029] A large amount of sealant that needs to be extruded and filled is stored in the storage tank 2. The cylinder 3 can control the push plate 301 to descend. The movement stroke of the push plate 301 is limited by the positioning block 501. The positioning block 501 is equipped with a pressure sensor 502 and is screwed to the positioning bar 5. When the cylinder 3 drives the push plate 301 to move downward until it contacts the pressure sensor 502, the cylinder 3 stops running. At this time, the extrusion rod 401 under the push plate 301 extrudes the sealant in the extrusion barrel 4 quantitatively, thereby realizing the quantitative extrusion operation. The extrusion amount is controlled by controlling the position of the positioning block 501 screwed to the positioning bar 5.

[0030] The front side of the base 1 is fixed with fixed rings 101 distributed at equal intervals, and an extrusion barrel 4 is fixed in each fixed ring 101, and an extrusion rod 401 is movably inserted in each extrusion barrel 4, and a discharge nozzle 404 is fixed through the bottom end of the extrusion barrel 4, and a traction rope 402 is fixed to the bottom end of the extrusion rod 401, and a steel ball 403 is fixed to the bottom end of the traction rope 402 through the discharge nozzle 404, and the steel ball 403 is covered with a sealing sleeve 4031;

[0031] The extrusion barrel 4 is fixed by the fixing ring 101, and a certain amount of sealant is stored in the extrusion barrel 4. When the extrusion rod 401 moves downward to extrude the sealant, the traction rope 402 and the steel ball 403 descend, and the discharge nozzle 404 is opened to extrude and fill the sealant. After the extrusion is completed, the extrusion rod 401 moves upward until the steel ball 403 and the sealing sleeve 4031 block the discharge nozzle 404. At this time, the connecting tube 405 is just connected to the inside of the extrusion barrel 4 for feeding.

[0032] An air compressor 201 is also fixed on the side of the storage tank 2 adjacent to the cylinder 3, and the air outlet pipe of the air compressor 201 is connected to the inside of the storage tank 2; the air compressor 201 can increase the pressure in the storage tank 2, so that when adding material to the extrusion barrel 4, the sealant will directly enter the extrusion barrel 4.

[0033] A tank cover 202 is screwed onto the feed inlet at the upper end of the storage tank 2; the tank cover 202 is used to close the feed inlet of the discharge pipe.

[0034] The inner diameter of the steel ball 403 and the sealing sleeve 4031 is larger than the inner diameter of the discharge nozzle 404, so that the discharge nozzle 404 can be easily sealed. The height of the extrusion rod 401 is larger than the height of the extrusion barrel 4; thus, when the extrusion rod 401 completely enters the extrusion barrel 4, the connecting tube 405 will still be blocked, so that it will not be replenished at this time.

[0035] A connecting pipe 405 is fixedly passed through the circumference of the extrusion cylinder 4, and one end of the connecting pipe 405 away from the extrusion cylinder 4 is fixedly passed through the storage tank 2; when the connecting pipe 405 is connected with the extrusion cylinder 4 and the storage tank 2, the extrusion cylinder 4 is replenished with materials.

[0036] The side of the positioning bar 5 away from the storage tank 2 is provided with positioning holes 503 distributed at equal intervals, and the side of the positioning block 501 close to the positioning bar 5 is fixed with a screw 5011, and the positioning bar 5 is screwed into the positioning hole 503 for positioning by the screw 5011;

[0037] The positioning block 501 is screwed into the positioning hole 503 via the screw 5011 to achieve the positioning operation.

[0038] The bottom surface of the push plate 301 is fixed with connecting rods matching the number of extrusion rods 401, and the push plate 301 is fixedly connected to the corresponding upper end of the extrusion rod 401 through the connecting rod; the push plate 301 is connected to the extrusion rod 401 through the connecting rod, so that the cylinder 3 drives the push plate 301 and the extrusion rod 401 performs linear displacement.

[0039] The specific working principle of the utility model is as follows: a large amount of sealant to be extruded and filled is stored in the storage tank 2, and the storage tank 2 is pressurized by the air compressor 201, so that when the material is added to the extrusion tube 4, the sealant will directly enter the extrusion tube 4 through the connecting pipe 405. Before extrusion, the positioning block 501 is screwed into the positioning hole 503 through the screw 5011 to determine the position of the pressure sensor 502. Then the cylinder 3 can control the push plate 301 to descend, so that the extrusion rod 401 descends, and the sealant in the extrusion tube 4 is squeezed out. During extrusion, the traction rope 402 and the steel ball 403 The cylinder 3 drives the push plate 301 to move downward until it contacts the pressure sensor 502, and then the cylinder 3 stops running to realize the quantitative extrusion operation. Subsequently, the pressure sensor 502 transmits a signal to the cylinder 3, and the cylinder 3 controls the push plate 301 to resume moving upward until the steel ball 403 and the sealing sleeve 4031 block the discharge nozzle 404. At this time, the connecting pipe 405 is connected to the inside of the extrusion barrel 4 for feeding. After a while, the extrusion operation can be carried out again, and the quantitative extrusion operation can be carried out continuously and uninterruptedly.

[0040] The above are only preferred embodiments of the present invention and do not limit the present invention. Any modification to the technical solutions recorded in the aforementioned embodiments and any equivalent replacement of some of the technical features therein, as well as any modification, equivalent replacement and improvement made, are within the protection scope of the present invention.
