Description

Technical Field

[0001] This utility model relates to the field of sponge flat cutting machine technology, specifically a pushing mechanism for a disc-type sponge flat cutting machine. Background Technology

[0002] As described in the published patent CN214213989U, "A Sponge Cutting Machine with a Fixing Mechanism," commonly used sponges are made of wood cellulose fibers or foamed plastic polymers. There are also natural sponges made from sponge animals, most of which are used for body cleaning or painting. Additionally, there are three other types of synthetic sponges made from materials such as low-density polyether (non-absorbent sponge), polyvinyl alcohol (highly absorbent material with no obvious pores), and polyester. In actual production, sponges are cut using a disc cutting machine. However, the disc on a traditional disc cutting machine is usually a flat circular plate, and the sponge blocks are typically placed directly on the disc. Due to the limited friction between the disc and the sponge blocks, the sponge blocks are prone to shifting during the cutting process, thus affecting the cutting effect.

[0003] In summary, during the use of some existing disc cutting machines, the limited friction between the disc and the sponge block causes the sponge block to easily deviate during the cutting process. Utility Model Content

An arched mounting arm fixed to the base is installed on the outer side of the working disc. The end of the arched mounting arm extends into the top of the mounting hole. An electric heating cutting blade spanning the working disc is installed on the arched mounting arm. The pushing mechanism includes a motor fixed on a base, a connecting rod fixed on the working shaft of the motor, a push rod rotatably connected to the connecting rod, and an elastic abutment fixed on the connecting rod to elastically engage with the push rod.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-12A material pushing mechanism for a disc-type sponge flat cutter includes a base 101, on which a working disc 102 is rotatably mounted. A mounting hole 103 is formed at the center of the working disc 102, and a pushing mechanism 104 is provided in the mounting hole 103. An arched mounting arm 105 fixed to the base 101 is installed on the outer side of the working disc 102. The end of the arched mounting arm 105 extends into the mounting hole 103. An electrothermal cutting blade 106 spanning across the working disc 102 is installed on the arched mounting arm 105. The pushing mechanism 104 includes a motor component 107 fixed on a base 101. A connecting rod 109 is fixed on the working shaft of the motor component 107. A push rod 110 is rotatably connected to the connecting rod 109. An elastic abutment 111 is fixed on the connecting rod 109 and elastically abuts against the push rod 110. Under the action of the elastic abutment 111, an obtuse angle is formed between the push rod 110 and the connecting rod 109 in the normal state. A limit assembly 112 is connected between the connecting rod 109 and the push rod 110. like Figure 1 As shown, during the processing, the sponge is first placed on the working disc 102. The working disc 102 is rotated by the auxiliary power component. The rotation of the working disc 102 drives the sponge to be fed. The push rod 110 is set below the arched mounting arm 105. The servo motor 107 drives the push rod 110 to rotate without interfering with the arched mounting arm 105. After idling, the push rod 110 abuts against the rear side of the sponge (during idling, the speed of the push rod 110 is slightly greater than the speed of the working disc 102). like Figure 2 As shown, the electrothermal cutting disc 106 is arranged along a straight line L1. If the push rod 110 is set to be collinear with the connecting rod 109, then during the process of the push rod 110 pushing the sponge, the sponge will naturally conform to the push rod 110. Figure 2 As can be seen, there will be an angle α between the push rod 110 and the electrothermal cutting disc 106 at this time. If the sponge is used for cutting in this way, the sponge will start cutting in an inclined manner, which will result in uneven force. The sponge will tend to deviate outward, affecting the cutting quality and cutting efficiency. like Figure 3As shown, under the combined action of the elastic ejection of the elastic abutment 111 and the limiting action of the limiting component 112, an obtuse angle is formed between the push rod 110 and the connecting rod 109 in normal condition. During the rotation of the push rod 110, a small pushing force is applied to the sponge, and the sponge will naturally adhere to the push rod 110 (until the sponge is cut, the rotation speed of the push rod 110 must be slightly greater than that of the working disc 102 so that the sponge adheres to the push rod 110). At this time, the reaction force of the sponge on the push rod 110 is small, and the elastic abutment 111 undergoes slight elastic deformation. At this time, the push rod 110 has a certain tilt angle, so that the initial cutting surface of the sponge and the electrothermal cutting disc 106 are in relatively parallel surface contact for cutting, so that the force on each part of the sponge is uniform. like Figure 3 , 4 As shown in Figure 5, during the sponge cutting process, the resistance from the electrothermal cutting plate 106 increases. At this time, the greater resistance experienced by the sponge will react on the push rod 110. After the push rod 110 experiences greater resistance, the elastic abutment 111 will undergo elastic deformation. During this process, the servo motor 107 drives the connecting rod 109 to rotate continuously, while the direction of the push rod 110 remains unchanged. The push rod 110 continuously compresses the elastic abutment 111 until the sponge cutting is completed. During the cutting process, the cutting surface of the sponge remains parallel to the electrothermal cutting plate 106. After the cutting is completed, the elastic abutment 111 resets. With the elastic ejection of the elastic abutment 111 and the limiting action of the limiting component 112, the push rod 110 and the connecting rod 109 return to an obtuse angle state. The elastic abutment 111 provides continuous and appropriate elastic support for the push rod 110, allowing the push rod 110 to deflect at an angle. Simultaneously, the limiting component 112 precisely controls the rotation amplitude of the push rod 110, preventing excessive tilting. Ultimately, the push rod 110 automatically adjusts to a suitable pushing angle based on the actual placement of the sponge on the working disc 102, effectively changing the contact between the sponge and the electrothermal cutting disc 106 from "point contact." Upgraded to "surface contact," surface contact not only significantly expands the contact area between the sponge and the cutting disc, but also ensures that the cutting force on the sponge is evenly distributed on the contact surface during cutting. On the one hand, it completely solves the problem of sponge deviation caused by uneven force, and on the other hand, it effectively avoids problems such as rough edges and dimensional deviations caused by excessive local force. It significantly improves the edge smoothness and dimensional accuracy of sponge cutting. Thirdly, in terms of operational stability and efficiency, the pushing mechanism 104 is fixed on the base 101 and forms a stable cooperative working relationship with the rotating working disc 102. The pushing of the push rod 110 can be precisely matched with the rotation rhythm of the working disc 102. Even if the friction between the sponge and the working disc 102 is limited, the continuous and uniform pushing force of the push rod 110 can firmly drive the sponge to move synchronously with the disc, avoiding the sponge from sliding or shifting on the disc. There is no need for the staff to frequently stop the machine to adjust the sponge position, which reduces the cost of manual intervention and improves the efficiency of continuous cutting. It should be noted that during the cutting process, the rotation speed of the working disc 102 can be appropriately reduced so that the operation of the push rod 110 can be better matched with the rotation of the working disc 102. The material pushing mechanism of this utility model adopts a design with a push rod 110 that can rotate elastically, so that the sponge always maintains surface contact with the electrothermal cutting disc 106 before and during cutting, thereby effectively avoiding uneven force and sponge deviation during cutting, and significantly improving cutting stability and work efficiency.

[0016] In this embodiment of the utility model, the end of the connecting rod 109 is fixedly equipped with an mounting arm 113, the mounting arm 113 is provided with a first pivot hole 114, and the end of the push rod 110 is provided with a second pivot hole 116. The second pivot hole 116 is equipped with a pivot component 115. The first pivot hole 114 and the second pivot hole 116 are concentrically fitted. The mounting arm 113 is rotatably connected to the pivot component 115 through the first pivot hole 114. The connecting rod 109 includes a first side 117 in contact with the sponge and a second side 118 away from the sponge. The elastic abutment 111 is installed at the end of the connecting rod 109 and close to the second side 118. like Figure 6 and Figure 7As shown, during the sponge cutting process, the sponge experiences increased resistance from the electrothermal cutting disc 106. This increased resistance causes the sponge to react against the push rod 110. Upon encountering this resistance, the push rod 110 rotates around the pivot 115. During this rotation, the elastic abutment 111, mounted on the end of the connecting rod 109 and close to the second side 118, undergoes elastic deformation. During this process, the servo motor 107 continuously drives the connecting rod 109 to rotate. However, because the push rod 110 rotates around the pivot 115, its direction remains unchanged. Simultaneously, the push rod 110 continuously compresses the elastic abutment 111 until the cutting is complete. (When the limiting component 112 is in place, the push rod 110 cannot rotate further.) Before cutting, under the combined action of the elastic ejection of the elastic abutment 111 and the limiting action of the limiting component 112, the push rod 110 rotates through the second pivot hole 116 in its normal state, forming an obtuse angle between the push rod 110 and the connecting rod 109, and the initial cutting surface of the sponge is parallel to the electrothermal cutting plate 106. During the cutting process, the push rod 110 continuously compresses the elastic abutment 111, causing the push rod 110 to rotate slowly and continuously, and the initial cutting surface of the sponge remains parallel to the electrothermal cutting plate 106. After the cutting is completed, the elastic abutment 111 resets, and under the combined action of the elastic ejection of the elastic abutment 111 and the limiting action of the limiting component 112, the push rod 110 and the connecting rod 109 return to the obtuse angle state, and the next round of pushing operation begins.

[0017] In this embodiment of the present invention, an elastic element mounting seat 119 is fixedly installed at the end of the connecting rod 109 near the second side 118, and an elastic element mounting hole 120 is opened at the front end of the elastic element mounting seat 119, and the elastic abutment 111 is installed in the elastic element mounting hole 120. like Figure 6 and Figure 7 As shown, by fixing the elastic element mounting base 119 to a specific position near the second side 118 at the end of the connecting rod 109, and using the elastic element mounting hole 120 at its front end to install the elastic abutment 111, the accuracy and stability of the force point of the elastic abutment 111 are ensured, and the stability of the elastic abutment 111 is effectively enhanced during the compression process of the push rod 110 on the elastic abutment 111.

[0018] In this embodiment of the present invention, the elastic abutment 111 includes a spring installed in the elastic mounting hole 120, and an arc-shaped abutment 122 fixed to the end of the spring. like Figure 8 and Figure 9As shown, by setting the arc-shaped abutment 122, the push rod 110 has a better elastic abutment effect on the spring during rotation, thus avoiding jamming.

[0019] In this embodiment of the present invention, the end of the push rod 110 is provided with an arc-shaped groove 123, and the end of the arc-shaped abutment 122 slides and abuts within the arc-shaped groove 123. like Figure 8 and Figure 9 As shown, by providing an arc-shaped groove 123 at the end of the push rod 110, the arc-shaped abutment 122 slides and abuts within the arc-shaped groove 123 during the rotation of the push rod 110, while the spring undergoes elastic deformation, thereby making the elastic abutment between the push rod 110 and the connecting rod 109 more stable.

[0020] In this embodiment of the utility model, the limiting component 112 includes a connecting rod mounting column 124 rotatably mounted on the end face of the connecting rod member 109 and a push rod mounting column 125 fixedly mounted on the end face of the push rod member 110. A rotation adjustment column 126 is rotatably mounted on the push rod mounting column 125, and a limiting rod 127 is fixedly mounted on the rotation adjustment column 126. The connecting rod mounting column 124 has a limiting hole 128, and the limiting rod 127 passes through the limiting hole 128. The outer wall of the limiting rod 127 is fixed with a front limiting block 129 for front-end limiting and a rear limiting block 130 for rear-end limiting. like Figure 3 , 10 As shown in Figure 11, under the elastic ejection action of the elastic abutment member 111, the front limiting block 129 and the limiting hole 128 engage in limiting abutment cooperation, so that an obtuse angle is formed between the push rod member 110 and the connecting rod member 109 under normal conditions. During the rotation of the push rod 110, a small pushing force is applied to the sponge, and the sponge will naturally adhere to the push rod 110. At this time, the elastic abutment 111 undergoes slight elastic deformation, and the angle of the push rod 110 does not rotate significantly until the cutting operation is carried out. During the cutting operation, the resistance experienced by the sponge from the electrothermal cutting disc 106 increases. This increased resistance acts on the push rod 110. During this process, the servo motor 107 drives the connecting rod 109 to rotate continuously. However, due to the resistance of the sponge, the direction of the push rod 110 remains unchanged. The push rod 110 elastically compresses the elastic abutment 111. At this time, the push rod 110 rotates around the pivot 115, and the rotation adjustment column 126 rotates on the push rod mounting column 125, thereby driving the limit rod 127 to rotate. Simultaneously, the limit rod 127... The moving link mounting column 124 rotates, while the limiting rod 127 slides within the limiting hole 128. The push rod 110 continuously compresses the elastic abutment 111. At this time, the push rod 110 continues to rotate around the rotating shaft 115, and the limiting rod 127 continues to slide within the limiting hole 128 until the rear limiting block 130 engages with the limiting hole 128, thus limiting the rotational adjustment between the push rod 110 and the connecting rod 109. This also prevents the push rod 110 from rotating excessively, which could affect the elastic reset effect of the elastic abutment 111.

[0021] In this embodiment of the present invention, an infrared sensor 131 is fixedly mounted on the push rod 110; By setting up infrared sensors, the contact between the push rod 110 and the sponge part can be intelligently monitored, improving the efficiency of automated processing and reducing the cost of manual intervention.

[0022] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
