Description

Technical Field

[0001] The utility model relates to the technical field of compressed towel production equipment, in particular to a material storage and buffering mechanism for rolling and compressing towels. Background Art

[0002] With the development of social economy and the improvement of people's living standards, the demand for service industries such as catering and tourism has also increased. While enjoying these services, the consumption of some consumables, such as compressed towels and disposable wet towels, has also increased significantly.

[0003] For compressed towel production equipment, application publication number CN115157756A discloses a full-servo compressed towel production process, which specifically discloses the following steps: a. Feeding: the raw material is in the form of a roll and is conveyed after being unwound by a reeling mechanism; b. Transverse folding: the conveying direction of the roll is defined as the longitudinal direction, and the width direction of the roll is the transverse direction. After unwinding, it is folded into three sections along the transverse direction by a transverse folding mechanism and then continued to be conveyed; c. Cutting: the raw material after transverse folding is passed through a cutting mechanism to form a single section of material with a certain length along the longitudinal direction; d. Longitudinal folding: the obtained single section of material is folded twice along the longitudinal direction by two longitudinal folding mechanisms to form a single material to be punched, and is sent into a feeding mechanism for continued conveying; e. Pressing and forming: the material to be punched obtained in step d is conveyed to the pressing mechanism; the pressing mechanism includes more than one pressing assembly, and each of the pressing assemblies includes a frame, a press for punching arranged on the frame, and four sets of forming molds arranged below the press. , a turntable that carries the mold and converts the workstations, a loading mechanism for pushing the material to be punched into the mold, and a unloading mechanism for pushing the compressed towel out of the pressing assembly. The compression station is located directly below the press, and the loading mechanism is located below the loading station. Located on both sides of the loading station and the compression station are a storage station and an unloading station, respectively. The above-mentioned stations can be cyclically converted by rotating the turntable; the above-mentioned step e includes: e1, loading: the obtained material to be punched is pushed by a loading mechanism and pushed into the mold of the pressing assembly located at the loading station; e2, storage: the mold after loading is completed is converted into the storage station by the turntable operation, and the loading station receives an empty mold, and repeats step e1 until the loading is completed again; e3, compression: after step e2, the turntable rotates, and the mold in the storage station in step e2 is rotated and sent to the compression station for compression by the press. After compression is completed, the press is reset, and the loading station receives an empty mold, and repeats step e1;

[0004] e4: Unloading: After compression is completed, the mold in the compression station is transported to the unloading station after being rotated by the turntable, and the unloading is completed by the unloading mechanism. At this time, the loading station receives the empty mold and repeats step e1. In addition, the feeding mechanism includes a horizontal conveyor belt assembly and a vertical conveyor belt assembly that cooperate with each other. The horizontal conveyor belt assembly includes multiple horizontal conveyor pulleys and two horizontal belt bodies wound around each of the horizontal conveyor pulleys. The vertical conveyor belt assembly includes multiple vertical conveyor pulleys and one or two vertical belt bodies wound around each of the vertical conveyor pulleys. The vertical belt body and one or two horizontal belt bodies are sandwiched together to convey the material to be stamped. The vertical belt body and the horizontal belt body are rope-shaped belt bodies.

[0005] While the feeding mechanism in the aforementioned full-servo compressed towel production process can be used for feeding, this design primarily utilizes the cooperation of vertical and horizontal belts to clamp and transport the workpiece. Because this feeding mechanism only has a single conveying channel for workpiece transport, it cannot synchronize and independently perform two processes without interruption. Therefore, it is necessary to invent a new material storage and buffering mechanism with feeding functionality that allows two processes to be synchronized and independently performed without interruption to meet diverse needs.

When one of the two material storage and cache components is rotating to collect material, the other component can proceed to the next process in a stopped state, that is, the two components can work independently of each other.

[0007] In order to achieve the above purpose, the technical solution of the utility model is:

The above arrangement enables the first material storage bottom mold and the second material storage bottom mold to work independently of each other without stopping.

[0009] Furthermore, the first driving wheel and the second driven wheel are respectively mounted on a first connecting shaft; one end of the first connecting shaft is connected to the output shaft of the first drive motor; the first driving wheel is fixed to the first connecting shaft; the second driven wheel is rotatably connected to the first connecting shaft via a bearing; the second driving wheel and the first driven wheel are respectively mounted on a second connecting shaft; one end of the second connecting shaft is connected to the output shaft of the second drive motor; the second driving wheel is fixed to the second connecting shaft; the first driven wheel is rotatably connected to the second connecting shaft via a bearing.

[0010] Furthermore, two baffles are provided opposite to each other and fixedly arranged, and the two ends of the first connecting shaft and the two ends of the second connecting shaft are connected to the two baffles respectively. The above arrangement can facilitate the positioning of the two connecting shafts.

[0011] Furthermore, two positioning brackets are respectively provided on the outer side of one of the baffles; the first drive motor and the second drive motor are respectively mounted on the two positioning brackets. The above arrangement can facilitate positioning of the first drive motor and the second drive motor.

[0012] Furthermore, the material holding groove is extended left and right.

[0013] Furthermore, the material clamping groove is provided to penetrate from left to right.

[0014] Furthermore, the wall surface of the material holding groove is in a downward convex arc shape.

[0015] Furthermore, the first and second storage base molds are each provided with eight material holding slots, and the slots are arranged in a front-to-back order. This arrangement allows the first and second storage base molds to simultaneously operate on eight workpieces, thereby improving work efficiency.

[0016] Furthermore, the length and width of the first material storage bottom mold are equal to the length and width of the second material storage bottom mold.

[0017] Furthermore, first connection holes are provided on the surfaces of both the first and second conveyor belts; second connection holes corresponding to the first connection holes are provided on the bottom surfaces of the material troughs of the first and second storage bottom molds, respectively; and a bolt is passed through each first connection hole and then connected to a nut.

Specifically, the first drive motor and the second drive motor can be used to respectively drive the first conveyor belt and the second conveyor belt to rotate, thereby synchronously driving the first storage bottom mold and the second storage bottom mold to move to realize feeding.

[0020] At the same time, since the axis of symmetry of the first storage bottom mold along the front-to-back direction coincides with the axis of symmetry of the second storage bottom mold along the front-to-back direction, the movement routes of the first storage bottom mold and the second storage bottom mold coincide, that is, the positions of the first storage bottom mold and the second storage bottom mold during movement can be repeated, and thus the functions of the first storage bottom mold and the second storage bottom mold can be designed to be the same, that is, the material receiving position and delivery position of the first storage bottom mold and the second storage bottom mold can be consistent. Therefore, this design allows the first storage bottom mold and the second storage bottom mold to cooperate with other mechanisms, and the other mechanisms can be implemented on the first storage bottom mold or the second storage bottom mold with only one set of actions, without the need to use different actions to implement them on the first storage bottom mold and the second storage bottom mold respectively.

[0021] Moreover, because the first storage bottom mold and the second storage bottom mold are driven by different motors respectively, this allows one of the two storage bottom molds to rotate to receive materials while the other can be in a stopped state to proceed to the next process; more specifically, when the first storage bottom mold is moving, the second storage bottom mold can be in a stopped state, and when the first storage bottom mold is in a stopped state, the second storage bottom mold can be moving, so that they can alternately perform different processes at the same time, that is, the two can work independently of each other without pausing, so as to meet the requirements of different processes, and it is highly practical.

[0036] The utility model will be further described below with reference to the accompanying drawings and specific embodiments. The following description is merely illustrative and does not limit the scope of protection of the utility model.

[0037] like Figure 1-Figure 5 As shown, a material storage and buffer mechanism for rolling and compressing towels includes a first material storage and buffer component 1 and a second material storage and buffer component 2.

[0038] like Figure 1-Figure 3 As shown, the first material storage buffer assembly 1 includes a fixed first driving motor 11, a first driving wheel 12 connected to the output shaft of the first driving motor 11, a fixed first driven wheel 13 that cooperates with the first driving wheel 12, a first conveyor belt 14 that is respectively connected to the first driving wheel 12 and the first driven wheel 13, and a first material storage bottom mold 15 that is installed on the outer surface of the first conveyor belt 14 and has a material clamping groove 3 at the outer end. Through the above arrangement, the first driving motor 11 can be used to conveniently drive the first driving wheel 12 to rotate, and the first driven wheel 13, the first conveyor belt 14 and the first material storage bottom mold 15 can be synchronously driven to achieve corresponding actions.

[0039] like Figure 1-Figure 3 As shown, the second material storage buffer assembly 2 includes a fixed second driving motor 21, a second driving wheel 22 connected to the output shaft of the second driving motor 21, a fixed second driven wheel 23 that cooperates with the second driving wheel 22, a second conveyor belt 24 that is respectively connected to the second driving wheel 22 and the second driven wheel 23, and a second material storage bottom mold 25 that is installed on the outer surface of the second conveyor belt 24 and has a material clamping groove 3 at the outer end. Similarly, through the above-mentioned arrangement, it is convenient to utilize the second driving motor 21 to drive the second driving wheel 22 to rotate, and can synchronously drive the second driven wheel 23, the second conveyor belt 24 and the second material storage bottom mold 25 to achieve corresponding actions.

[0040] like Figure 1-Figure 3 As shown, the first conveyor belt 14 and the second conveyor belt 24 are arranged side by side left and right, and the first storage bottom mold 15 and the second storage bottom mold 25 are distributed front and back.

[0041] like Figure 1-Figure 3 As shown, one end of the first storage die 15 extends toward the second conveyor belt 24 to the top of the second conveyor belt 24, and the other end is connected to the first conveyor belt 14. One end of the second storage die 25 extends toward the first conveyor belt 14 to the top of the first conveyor belt 14, and the other end is connected to the second conveyor belt 24. The symmetry axis of the first storage die 15 along the front-to-back direction coincides with the symmetry axis of the second storage die 25 along the front-to-back direction. Therefore, this arrangement allows the movement paths of the first storage die 15 and the second storage die 25 to coincide.

[0042] To sum up, the overall structure of the utility model is simple and reasonable. Specifically, the first drive motor 11 and the second drive motor 21 can be used to respectively drive the first conveyor belt 14 and the second conveyor belt 24 to rotate, thereby synchronously driving the first storage bottom mold 15 and the second storage bottom mold 25 to move in order to realize feeding. At the same time, since the symmetry axis of the first storage bottom mold 15 along the front-to-back direction coincides with the symmetry axis of the second storage bottom mold 25 along the front-to-back direction, the movement routes of the first storage bottom mold 15 and the second storage bottom mold 25 coincide, that is, the positions of the first storage bottom mold 15 and the second storage bottom mold 25 during the movement process can be repeated, and thus the functions of the first storage bottom mold 15 and the second storage bottom mold 25 can be designed to be the same, that is, the material receiving position and the delivery position of the first storage bottom mold 15 and the second storage bottom mold 25 can be consistent; therefore, this design enables the first storage bottom mold 15 and the second storage bottom mold 25 to cooperate with other mechanisms, and the other mechanisms can only need one set of actions to move the first storage bottom mold 15 or the second storage bottom mold 25. The operation is implemented on the material storage bottom mold 25, and there is no need to adopt different actions to implement them on the first material storage bottom mold 15 and the second material storage bottom mold 25 respectively; and because the first material storage bottom mold 15 and the second material storage bottom mold 25 are driven by different motors respectively, this allows one of the two material storage bottom molds to rotate to receive the material while the other can be in a stopped state to proceed to the next process; more specifically, when the first material storage bottom mold 15 is moving, the second material storage bottom mold 25 can be in a stopped state, and when the first material storage bottom mold 15 is in a stopped state, the second material storage bottom mold 25 can be moving, so that they can alternately perform different processes at the same time, that is, the two can work independently of each other without pausing, so as to meet the requirements of different processes, and are highly practical.

[0043] like Figure 1-Figure 3 As shown, in this embodiment, the length and width of the first storage mold 15 are equal to the length and width of the second storage mold 25, so that the sizes of the first storage mold 15 and the second storage mold 25 are substantially the same. Specifically, the lengths of the first storage mold 15 and the second storage mold 25 are both greater than the distance between the outer sides of the first conveyor belt 14 and the outer sides of the second conveyor belt 24, that is, the two ends of the first storage mold 15 and the two ends of the second storage mold 25 extend outward from the first conveyor belt 14 and the second conveyor belt 24, respectively.

[0044] like Figure 1-Figure 3As shown, preferably, the first driving wheel 12 and the second driven wheel 23 are respectively mounted on a first connecting shaft 16; one end of the first connecting shaft 16 is connected to the output shaft of the first drive motor 11; the first driving wheel 12 is fixed on the first connecting shaft 16, that is, the first driving wheel 12 rotates synchronously with the rotation of the first connecting shaft 16; the second driven wheel 23 is rotatably connected to the first connecting shaft 16 by a bearing (not shown), that is, the second driven wheel 23 rotates synchronously without following the rotation of the first connecting shaft 16. Therefore, the above arrangement can facilitate the installation of the first driving wheel 12 and the second driven wheel 23. In addition, the connection relationship between the second driven wheel 23, the bearing and the first connecting shaft 16 is prior art and will not be described in detail here.

[0045] like Figure 1-Figure 3 As shown, preferably, the second driving wheel 22 and the first driven wheel 13 are respectively mounted on a second connecting shaft 26; one end of the second connecting shaft 26 is connected to the output shaft of the second drive motor 21; the second driving wheel 22 is fixed on the second connecting shaft 26, that is, the second driving wheel 22 rotates synchronously with the rotation of the second connecting shaft 26; the first driven wheel 13 is rotatably connected to the second connecting shaft 26 by a bearing (not shown), that is, the first driven wheel 13 rotates synchronously without following the rotation of the second connecting shaft 26. Therefore, the second driving wheel 22 and the first driven wheel 13 can be easily installed through the above arrangement. In addition, the connection relationship between the first driven wheel 13, the bearing and the second connecting shaft 26 is prior art and will not be described in detail here.

[0046] like Figure 1-Figure 3 As shown, preferably, two baffles 4 are provided opposite and fixedly arranged; the two ends of the first connecting shaft 16 and the two ends of the second connecting shaft 26 are respectively connected to the two baffles 4. Therefore, the above arrangement can facilitate the positioning of the first connecting shaft 16 and the second connecting shaft 26, thereby also facilitating the positioning of other components.

[0047] like Figure 1-Figure 3 As shown, preferably, two positioning brackets 5 are respectively provided on the outer side of a baffle 4; the first drive motor 11 and the second drive motor 21 are respectively mounted on the two positioning brackets 5. Therefore, the above arrangement can facilitate the positioning of the first drive motor 11 and the second drive motor 21.

[0048] like Figure 1-Figure 3 As shown, in this embodiment, the material slot 3 is extended left and right. Specifically, the material slot 3 is provided through the left and right sides. In addition, the wall surface of the material slot 3 is in a downwardly convex arc shape, so that the material slot 3 can better match the shape of the curled compressed towel, thereby facilitating the positioning of the workpiece.

[0049] like Figure 1-Figure 3As shown, preferably, eight material holding slots 3 are provided on each of the first and second material storage bottom molds 15 and 25, and the material holding slots 3 are distributed in sequence front to back. Therefore, by providing eight material holding slots 3 on each of the first and second material storage bottom molds 15 and 25, eight workpieces can be operated simultaneously, thereby improving work efficiency.

[0050] like Figure 2 As shown, preferably, first connection holes are provided on the surfaces of the first conveyor belt 14 and the second conveyor belt 24 (not shown due to visual obstruction); second connection holes 6 corresponding to the first connection holes are provided on the bottom surfaces of the material trough 3 of the first storage bottom mold 15 and the second storage bottom mold 25, respectively; and a bolt is passed through each first connection hole and then connected to a nut. Therefore, the above arrangement allows the first storage bottom mold 15 to be stably mounted on the first conveyor belt 14, and the second storage bottom mold 25 to be stably mounted on the second conveyor belt 24.

[0051] Combine Figure 4 and Figure 5 , the specific use principle of the utility model is introduced below to facilitate understanding of the utility model:

[0052] First, a stamping mechanism 7 is installed above the present invention, and the stamping mechanism 7 includes a fixed stamping cylinder 71, a stamping plate 72 that is movably installed on the output shaft of the stamping cylinder 71 and is located above the first storage bottom mold 15 and the second storage bottom mold 25; a plurality of stamping parts 73 that respectively cooperate with a plurality of card slots 3 are provided at the bottom of the stamping plate 72, and then a pushing mechanism 8 is installed on one side of the present invention, and the pushing mechanism 8 includes a fixed pushing cylinder 81 and a plurality of pushing rods 82 that are movably installed on the output shaft of the pushing cylinder 81 and are used to respectively cooperate with a plurality of card slots 3.

[0053] During the specific operation, in the first step, the first driving motor 11 drives the first material storage bottom mold 15 to move forward to a preset position (i.e., the material receiving position) through the first conveyor belt 14. At this time, the first material storage bottom mold 15 is located at the material receiving station; then, the workpieces (not shown in the figure) are transported backward one by one to the material clamping groove 3 of the first material storage bottom mold 15; and, after the first material clamping groove 3 of the first material storage bottom mold 15 receives a workpiece, the first driving motor 11 continues to drive the first material storage bottom mold 15 to move forward a certain distance, so that the second material clamping groove 3 can be used to continue to receive the second workpiece, and this operation is carried out until all the material clamping grooves 3 on the first material storage bottom mold 15 are filled with workpieces, that is, the material storage caching operation is realized;

[0054] Next, after all the card slots 3 on the first material storage bottom die 15 are filled with workpieces, the first material storage cache motor 11 continues to drive the first material storage bottom die 15 to rotate until it is delivered to the bottom of the stamping plate 72 (i.e., the delivery position), that is, the first material storage bottom die 15 is now located at the position of the stamping station; at the same time, the second material storage cache motor 21 continues to drive the second material storage bottom die 25 forward to the preset position through the second conveyor belt 24, and the second material storage bottom die 25 is now also located at the position of the material receiving station and its position is the same as the previous first material storage bottom die 15, so as to seamlessly continue to receive workpieces and facilitate material storage caching;

[0055] Next, after the first material storage bottom die 15 is moved into place, the punching cylinder 71 drives the punching plate 72 to move downward, so that each punching portion 73 falls exactly into each clamping groove 3 of the first material storage bottom die 15, thereby pressing each workpiece to make each workpiece compacted. Of course, the degree of compaction of the workpiece will not be too large to avoid damage to the workpiece; then, the punching cylinder 71 drives the punching block 72 to return to its original position;

[0056] It can be seen that the storage die not only serves as the die when receiving the material, but also needs to serve as the die for the workpiece during the stamping process;

[0057] Next, the push cylinder 81 drives the push rod 82 to push out, so that each push rod 82 is inserted horizontally into each clamping groove 3, and at the same time pushes each workpiece to move away from the clamping groove 3 until each workpiece enters the next process;

[0058] Next, after the workpiece of the first storage die 15 is pushed out, the various material slots 3 of the second storage die 25 have just received multiple workpieces, that is, the first storage die 15 and the second storage die 25 can work independently of each other; then the first storage buffer motor 11 and the second storage buffer motor 21 continue to drive the first storage die 15 and the second storage die 25 to rotate respectively, so that the second storage die 25 moves to the bottom of the punching block 72 (i.e., the delivery position), and the first storage die 15 moves to the receiving position to receive the workpiece again. Therefore, the first storage die 15 and the second storage die 25 have the same function and can be used freely and interchangeably.

[0059] The present invention is not limited to the above-mentioned embodiments. If various changes or modifications to the present invention do not depart from the spirit and scope of the present invention, and if these changes and modifications fall within the scope of the claims and equivalent technologies of the present invention, the present invention is also intended to include these changes and modifications.
