Description

TECHNICAL FIELD

[0001] The utility model belongs to foaming filling technical field, especially relate to a novel box foaming filling system automatic gun wiping mechanism. BACKGROUND

[0002] Box foaming filling technology is widely used in modern industry, especially in the production process of refrigerator, freezer and other thermal insulation equipment. The process realizes its thermal insulation performance by injecting foaming material into the box. However, the cleaning problem of filling gun head is one of the key factors affecting production efficiency and product quality in the process of box foaming filling. Due to the high viscosity and rapid solidification characteristics of foaming material, the filling gun head is easy to attach residual material after being used for many times. If not cleaned in time, the residual material may block the gun head, affect the filling accuracy and consistency of the subsequent, and even cause equipment failure and production stop. Therefore, the automatic cleaning of the filling gun head becomes an important issue to improve the working efficiency of the foaming filling system and the product quality.

[0003] In order to solve the above problems, the existing filling gun head cleaning method mainly relies on manual operation. Usually, after each filling is completed, the operator needs to manually wipe the residual material on the gun head. This method has many shortcomings: first, manual cleaning has the problems of low efficiency and high labor intensity, especially on the production line with high automation, manual cleaning cannot keep up with the fast production rhythm; second, the stability of manual operation is poor, and the cleaning is not thorough or the force is uneven, which may cause the residual material not to be completely removed, affecting the filling effect of the next time; third, long-term frequent manual operation increases the use and maintenance cost of the equipment, and also increases the risk of workers contacting chemical materials, which has certain safety hidden dangers, and becomes the immediate problem of foaming filling industry, which needs to be solved urgently. INVENTION CONTENTS

[0004] The utility model provides a novel box foaming filling system automatic gun wiping mechanism in view of the deficiency of prior art, and the specific technical scheme is as follows:

[0005] The utility model provides a novel box foaming filling system automatic gun wiping mechanism, including the lifting cylinder that the horizontal extension connecting frame top erects, its push part is connected with '' L '' shape bending connecting plate, and is pasted with rotary cylinder in the vertical surface of connecting plate, is used for the up-down reciprocating motion of rotary cylinder, the gun head scraper is clamped to the end face of rotary cylinder, the gun head scraper is inverted '' F '' shape, and the board side of gun head scraper extends outward and is equipped with two '' gate '' shape notches that are parallel and opposite to the filling gun head, and the lower edge of '' gate '' shape notch is all equipped with chamfer, and the hollow area is formed in the notch in the rotation process of rotary cylinder driven gun head scraper, and is used for the automatic residual material cleaning of filling gun head.

[0006] As an optimal technical scheme of the utility model, the upper groove in the two upper and lower parallel and directly opposite to the filling gun head's "door" shaped notches is the first gun wiping groove, and a plurality of parallel triangular comb teeth are symmetrically connected along the left and right edges of the first gun wiping groove, the comb teeth are fixed through magnetic force adsorption with the first gun wiping groove, and are used for breaking the large residual material of the filling gun head edge.

[0007] As an optimal technical scheme of the utility model, the lower groove in the two upper and lower parallel and directly opposite to the filling gun head's "door" shaped notches is the second gun wiping groove, and a plurality of oblique semicircular rubber teeth are symmetrically arranged along the left and right edges of the second gun wiping groove, and are staggered with the comb teeth up and down, and are used for scraping the small residual material of the filling gun head edge.

[0008] As an optimal technical scheme of the utility model, the second gun wiping groove's notch top edge is attached with a convex elastic scraper, and is used for wiping the residual material of the filling gun head.

[0009] As an optimal technical scheme of the utility model, the bending connecting plate bending portion is provided with symmetrical mounting grooves, and is detachably connected with the rotary air cylinder through bolts.

[0010] The utility model has the advantages of:

[0011] The novel box foaming filling system's automatic gun wiping mechanism has remarkable beneficial effects in design, especially in improving the filling gun head cleaning efficiency and automation level. First, through the cooperation of the lifting cylinder and the "L" shaped bending connecting plate, the system can realize the up and down movement and height adjustment of the gun head scraper, so as to ensure that the scraper can accurately fit the surface of the filling gun head in the gun wiping process. This design solves the problem of inconsistent angle and incomplete cleaning in the prior art, so that the scraping effect is more uniform and comprehensive.

[0012] The unique structure design of the gun head scraper is also one of the highlights of the system. The scraper is in inverted "F" shape, and upper and lower parallel "door" shaped notches are extended on the side surface, which makes the scraper accurately clean the key parts of the filling gun head in the scraping process. Through the design of the "door" shaped notch, the scraper can not only remove the residual material on the front of the gun head, but also can simultaneously remove the adhering material on the side of the gun head, so as to ensure that the residual material on the surface of the whole gun head is cleaned more thoroughly. Compared with the traditional manual plane hanging and taking, the design of inverted "F" shape structure significantly improves the cleaning coverage, so that the gun wiping effect is more efficient and comprehensive.

[0013] In addition, the chamfer design of the notch lower edge further enhances the cleaning performance of the system. The chamfer can effectively guide the residual material into the interior of the notch, thereby avoiding the outward diffusion and ejection of the residual material during the cleaning process, largely solving the problems of incomplete cleaning and re-attachment of residual material in the prior art, and improving the efficiency and accuracy of the scraping operation. At the same time, the chamfer also reduces the friction between the gun head and the scraper, prolonging the service life of the equipment.

[0014] Secondly, the introduction of the rotary cylinder enables the scraper to realize rotary cleaning on the basis of up-down reciprocating movement. Through the rotation of the rotary cylinder, the scraper can not only realize simple scraping action during gun wiping, but also form a more complex cleaning trajectory. The hollow area formed by the rotary movement of the scraper in the notch can effectively prevent the residual material from accumulating in the interior of the gun head during gun wiping, thereby greatly improving the completeness and consistency of cleaning. Compared with the single scraper movement in the prior art, the system greatly enhances the cleaning effect by adding rotary movement, and reduces the frequency of manual intervention.

[0015] In summary, the new automatic gun wiping mechanism effectively overcomes many shortcomings in the prior art through unique mechanical design and multi-directional cleaning function. The traditional cleaning method relies on manual scraping, which is limited in cleaning effect and can easily cause the blockage of the filling gun head and even the stoppage of the production line. The mechanism not only can automatically complete the cleaning operation, significantly reducing the demand for manual operation, but also ensures the efficiency and thoroughness of each cleaning through the optimization of the scraper structure and the cooperation of the rotary movement, thereby improving the automation level of the foaming and filling system, effectively reducing the failure rate and downtime of the equipment in actual production, and improving the production efficiency and product quality.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical scheme and advantages of the utility model more clearly, the following will be further described in detail. It should be understood that the specific embodiments described herein are only used to explain the utility model, and are not used to limit the utility model.

[0022] Embodiment one

[0023] To solve the technical problems in the background art, a new type of box foaming filling system automatic gun wiping mechanism is given as follows:

[0024] In combination with Figure 1 The new type of box foaming filling system automatic gun wiping mechanism includes a lifting cylinder 2 erected on the top of the transversely extending connecting frame 1, the pushing part 21 of the lifting cylinder 2 is connected with an “L”-shaped bent connecting plate 3, a rotary cylinder 4 is attached to the inner vertical surface of the connecting plate, the rotary cylinder 4 is used for reciprocating movement up and down, a gun head scraping plate 5 is clamped on the end surface of the rotary cylinder 4, the gun head scraping plate 5 is in the shape of an inverted “F”, two “door”-shaped notches are arranged on the plate side of the gun head scraping plate 5 and extend outward, the two notches are parallel to each other and face the filling gun head 6, and the lower edges of the two notches are both provided with chamfers, a hollow area is formed in the notches during the rotation of the gun head scraping plate 5 driven by the rotary cylinder 4, and the hollow area is used for automatic residual material cleaning of the filling gun head 6.

[0025] Through the above technical scheme, the mechanism is outstanding in improving the cleaning efficiency and automation level of the filling gun head 6. First, through the cooperation of the lifting cylinder 2 and the “L”-shaped bent connecting plate 3, the system can realize the up and down movement and height adjustment of the gun head scraping plate 5, so as to ensure that the scraping plate can accurately fit the surface of the filling gun head 6 during the gun wiping process. This design solves the problem of inconsistent scraping angle and incomplete cleaning in the prior art, so that the scraping effect is more uniform and comprehensive.

[0026] Moreover, the unique structure design of the gun head scraping plate 5 is also one of the highlights of the system. The scraping plate is in the shape of an inverted “F”, and the “door”-shaped notches are arranged on the side of the scraping plate and extend upward and downward, which makes the scraping plate accurately align with the key parts of the filling gun head 6 during the scraping process. Through the design of the “door”-shaped notches, the scraping plate can not only clean the residual material on the front of the gun head, but also simultaneously scrape the attachments on the side of the gun head, so as to ensure that the residual material cleaning of the entire gun head surface is more thorough. Compared with the traditional manual planar hanging and taking, the design of the inverted “F” structure significantly improves the cleaning coverage, so that the gun wiping effect is more efficient and comprehensive.

[0027] Secondly, the chamfered design of the bottom edge of the notch further enhances the system's cleaning performance. This chamfer effectively guides residual material into the notch, preventing it from spreading and being thrown outward during the cleaning process. This significantly addresses the issues of incomplete cleaning and re-adherence of residual material in existing technologies, improving the efficiency and accuracy of the scraping operation. Furthermore, the chamfer reduces friction between the gun tip and the scraper, extending the service life of the equipment.

[0028] Furthermore, the introduction of the rotary cylinder 4 enables the scraper to perform rotary cleaning in addition to its up-and-down reciprocating motion. Driven by the rotation of the rotary cylinder 4, the scraper can not only perform simple scraping actions during the gun cleaning process, but can also form a more complex cleaning trajectory. This rotary motion, combined with the hollow area formed by the rotation of the notch, can effectively prevent residual material from accumulating inside the gun head during the gun cleaning process, thereby significantly improving the thoroughness and consistency of cleaning. Compared to the single manual scraper in the existing technology, this system effectively enhances the cleaning effect and reduces the frequency of manual intervention by adding rotary motion.

[0029] In summary, this new automatic gun cleaning mechanism effectively overcomes many shortcomings of the existing technology through its unique mechanical design and multi-faceted cleaning functions. Traditional cleaning methods often rely on manually held scrapers, which have limited cleaning effectiveness and can easily lead to clogging of the filling gun head 6 and even production line stagnation. However, this mechanism not only automatically completes the cleaning operation, significantly reducing the need for manual operation, but also ensures the efficiency and thoroughness of each cleaning through the optimization of the scraper structure and the coordination of the rotary motion. This not only improves the automation level of the foam filling system, but also effectively reduces the failure rate and downtime of the equipment in actual production, thereby improving production efficiency and product quality.

[0030] Example 2

[0031] Combine Figure 2 As shown, based on the above embodiment, this embodiment further provides the following content:

[0032] In this embodiment, the upper groove of the two "door"-shaped grooves that are parallel to each other and facing the filling gun head 6 is the first gun wiping groove 51, and a plurality of parallel triangular comb teeth 511 are symmetrically connected along the left and right edges of the first gun wiping groove 51. The comb teeth 511 are fixed to the first gun wiping groove 51 by magnetic adsorption and are used to crush large pieces of residual materials at the edge of the filling gun head 6.

[0033] The lower groove of the two "door"-shaped grooves that are parallel to each other and facing the filling gun head 6 is the second gun cleaning groove 52, and a plurality of oblique semicircular rubber teeth 521 are symmetrically arranged along the left and right edges of the second gun cleaning groove 52, and are staggered with the comb teeth 511 up and down, for scraping off small pieces of residual material on the edge of the filling gun head 6.

[0034] The top edge of the slot of the second gun wiping groove 52 is attached with a raised elastic scraper 522 for removing the residual material from the gun head 6.

[0035] Through the above technical scheme, the present application provides an effective solution to the automatic gun wiping problem during the box foaming filling process, which has significant advantages over the prior art. In the operation process of the traditional foaming filling equipment, residual material is easily accumulated on the edge of the gun head. If not cleaned in time, it will not only affect the filling accuracy, but also lead to poor filling effect, and even block the gun head, thereby affecting the production efficiency. The cleaning method in the prior art is mostly manual or simple mechanical cleaning, which is not only low in efficiency, but also easy to cause secondary pollution, and it is difficult to completely remove the residual material, especially for large and small pieces of residual material.

[0036] Firstly, by designing the upper and lower parallel gun wiping grooves in the gun head scraper 5, the problem of removing residual material from the gun head is effectively solved. The upper slot, i.e. the first gun wiping groove 51, is connected by multiple triangular comb teeth 511 symmetrically connected on both sides by magnetic force adsorption. Through the shape design of the comb teeth 511, the residual material can be effectively and quickly combed, and the large residual material attached to the edge of the gun head can be quickly broken, avoiding its accumulation or adhesion on the gun head. The magnetic force adsorption connection makes the gun wiping groove more stable when cleaning the gun head, effectively improving the cleaning efficiency.

[0037] Secondly, the design of the lower slot further optimizes the treatment of small pieces of residual material on the edge of the gun head 6. The second gun wiping groove 52 is arranged with semicircular rubber teeth 521 symmetrically on both sides, which are arranged in staggered positions with the comb teeth 511, and can flexibly deal with small pieces of residual material on the edge of the gun head. The obliquely arranged rubber teeth 521 are soft and have a certain elasticity, which can ensure the thoroughness of cleaning and not damage the surface of the gun head. Compared with the manual tool wiping in the prior art, this design can protect the equipment from damage caused by improper cleaning.

[0038] In addition, the top of the second gun wiping groove 52 is also attached with an elastic scraper 522. The protruding design of the scraper 522 makes the residual material on the front of the gun head be completely removed, ensuring that the gun head is in a clean state before each filling. This design significantly reduces the accumulation and secondary pollution of residual material, improves the service life of the equipment, and further ensures the accuracy and consistency of foaming filling.

[0039] In summary, the design of the present application solves the problems of incomplete cleaning, gun head wear and low efficiency in the traditional gun wiping process by separately treating large and small pieces of residual material and introducing a multi-level and multi-angle cleaning mechanism, greatly improving the automation level and production efficiency of box foaming filling.

[0040] Example three

[0041] Combination Figure 2 Based on the above embodiments, the present embodiment further provides the following content as shown in the drawings:

[0042] In the present embodiment, the bending connecting plate 3 is provided with symmetrical mounting grooves 31 at the bending position, and is detachably connected with the rotary air cylinder 4 through bolts.

[0043] Through the above technical solution, the mounting groove 31 of the bending connecting plate 3 is designed to make the automatic gun wiping debugging of the equipment more convenient and efficient during the box foaming filling process. First, the symmetrical mounting grooves 31 provided at the bending position make the connection more flexible, which is convenient for adjusting the position of the equipment, so as to meet the needs of different working conditions. Secondly, through the detachable connection mode of the bolt and the rotary air cylinder 4, the debugging personnel can quickly replace or adjust the equipment components, which greatly improves the debugging efficiency and reduces the downtime. Finally, this design is convenient for maintenance and repair, reduces the occurrence rate of equipment failure, and improves the reliability and stability of the system.

[0044] The working principle and use process of the utility model are as follows:

[0045] First, the "L" shaped bending connecting plate 3 is controlled to move up and down by the lifting cylinder 2, so as to adjust the position of the gun wiping mechanism, so that it is aligned with the filling gun head 6. When the filling gun head 6 enters the first gun wiping groove 51 of the gun head scraping plate 5, the triangular comb teeth 511 will break the large residual material on the edge of the gun head, and then the gun head continues to enter the second gun wiping groove 52. The semicircular rubber teeth 521 in the second gun wiping groove 52 are responsible for scraping the smaller residual material, and the rubber teeth 521 are arranged obliquely and staggered with the comb teeth 511, which can more comprehensively clean the residual material on the surface of the gun head. When the filling gun head 6 completely enters the slot during the rotation of the scraping plate, the rotary air cylinder 4 drives the gun head scraping plate 5 in the shape of "F" to rotate, and starts the final cleaning. At this time, the gun head will pass through the convex elastic scraper 522 at the top of the second gun wiping groove 52, and finally wipe off the residual material, and the cleaning is completed.

[0046] The above only describes the preferred embodiments of the utility model, and does not limit the utility model, and any modification, equivalent replacement and improvement made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
