Description

Technical Field

[0001] The utility model relates to the field of sponge processing, in particular to an automatic telescopic sponge supporting device. Background Art

[0002] Sponge cutting machines are used to cut and separate sponges. When cutting sponges, a conveyor belt moves the sponge under a gantry, where blades on the gantry cut the sponge. As the sponge moves along the conveyor belt toward the gantry, it can't maintain its longitudinal axis perpendicular to the gantry. This back-and-forth movement can cause positional deviations, affecting cutting accuracy. Therefore, sponge clamps are added on both sides of the sponge conveyor belt to support the sponge and prevent it from separating or tipping over during the cutting process, which could affect cutting accuracy.

[0003] At present, most of the existing sponge clamping plates are fixed, such as an automatic sponge supporting system for sponge processing mentioned in patent CN218950198U, a sponge cutting machine mentioned in patent CN218195545U, and an automatic lateral sponge supporting synchronous operation device mentioned in patent CN209380865U.

[0004] In the above patents, the plates used to clamp the sponges are all fixed plates, that is, their sizes are fixed. However, in actual production, the sizes of the sponges used for cutting are not fixed, that is, the sizes of the sponges vary. In order to be suitable for clamping sponges of various sizes, there are two conventional processing methods: one is to directly use a longer clamping plate to clamp the sponge, and the other is to design a variety of clamping plates of different sizes for matching and replacement according to sponges of different sizes.

[0005] Of the two solutions mentioned above, the first solution requires the clamping plate to be very long in order to be applicable to sponges of larger specifications as much as possible. However, it is more troublesome to use such a long clamping plate to clamp small-sized sponges. Since the length of the clamping plate is much longer than the length of the sponge, the clamping force is different when the sponge is clamped at different positions of the clamping plate. If the clamping force is too small, the sponge will still become loose. If the clamping force is too large, the sponge will easily deform, affecting the accuracy of sponge cutting. Therefore, it is very important to choose a suitable clamping position. The second solution, although it is possible to select suitable clamping plates to clamp the sponge according to sponges of different sizes to ensure that the sponge is well clamped, it is necessary to process multiple clamping plates of different sizes in advance, which increases the company's cost, and it is very troublesome to replace the clamping plates back and forth for sponges of different sizes.

[0028] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0029] like Figure 1-Figure 5 An automatic telescopic sponge support device is shown. The automatic telescopic sponge support device is installed on a sponge cutting machine and is used to clamp the sponge. The sponge cutting machine includes a sponge conveyor belt and a cutting gantry 2. The cutting gantry 2 spans both sides of the sponge conveyor belt 1 in the width direction. A cutting knife belt is also installed on the cutting gantry 2. The sponge conveyor belt 1 is installed on a conveying bracket. Sponge support brackets 3 are also provided on both sides of the sponge conveyor belt 1. The automatic telescopic sponge support device is installed on the sponge support bracket 3. The cotton support bracket 3 includes a fixed cotton support bracket fixed on the conveying bracket and a movable cotton support bracket movably provided on the fixed cotton support bracket. The automatic telescopic sponge support device is installed on the movable cotton support bracket and moves with the movable cotton support bracket. In this embodiment, the specific active structure and action principle of the movable cotton support bracket are prior art. Reference can be made to the automatic lateral cotton support synchronous operation device mentioned in patent CN209380865U, which will not be described in detail in this utility model.

[0030] like Figure 2 As shown in the schematic diagram, the automatic telescopic sponge support device includes

[0031] Two clamping plate bodies are respectively installed on two movable cotton supporting brackets, and are located on both sides of the width direction of the sponge conveyor belt 1. The clamping plate body is composed of several clamping plates 4 distributed in parallel along the conveying direction of the sponge conveyor belt 1. The clamping plates 4 are rectangular plates. The clamping plates 4 are driven to separate or close from each other by an opening and closing mechanism, thereby realizing the change of the size of the clamping plate body in the conveying direction of the sponge conveyor belt 1.

[0032] The upper and lower sides of the splint 4 are respectively connected to a connecting plate 43 extending horizontally in the direction of the movable cotton supporting bracket. The upper and lower sides of the horizontal movable cotton supporting bracket are also respectively installed with a translation guide rail extending along the conveying direction of the sponge conveyor belt 1. At the same time, a translation slider that cooperates with the translation guide rail is installed on the connecting plate 43. The cooperation between the translation guide rail and the translation slider provides a good foundation for the subsequent smooth separation or closing of the splint 4.

[0033] Among the splints 4, the two splints 4 located on the outside are defined as outer splints 42, and the splints located between the two outer splints 42 are defined as inner splints 41. The opening and closing mechanism is as follows:

[0034] A first connecting member is also connected to the side of each inner plywood 41 away from the center of the sponge conveyor belt 1. The first connecting member includes a pair of first connecting rods 411 hinged in an X shape. The first connecting rod 411 is a long square tube. The hinge point of the two first connecting rods 411 is located in the middle of the inner plywood 41, and the hinge point is defined as a first hinge point 412. The two sides of the two first connecting rods 411 extend out of the inner plywood 41 from the two sides of the inner plywood 41 respectively. In the two adjacent first connecting members, the two first connecting rods 411 constituting the same first connecting member are hinged one-to-one with the two first connecting rods 411 of the other first connecting member, and the hinge point of the hinge is defined as the second hinge point 413. In the two first connecting members distributed at intervals, the two first connecting rods 411 constituting the same first connecting member are hinged one-to-one with the two first connecting rods 411 of the other first connecting member, and the hinge point of the hinge is defined as the third hinge point 414.

[0035] There are five hinge points distributed on the same first connecting rod 411, namely a first hinge point 412 located in the middle position of the first connecting rod 411, two second hinge points 413 located on both sides of the first hinge point 412, and two third hinge points 414 located outside the two second hinge points 413.

[0036] A second connecting piece is also connected to the side of the outer splint 42 away from the center of the sponge conveyor belt 1, and the second connecting piece includes a pair of second connecting rods 421 hinged in a V shape, and the openings of the second connecting pieces of the two outer splints 42 are arranged opposite to each other, the second connecting rod 421 is also a long square tube, and the length of the second connecting rod 421 is shorter than the length of the first connecting rod 411, one side of the two second connecting rods 421 is hinged at the middle position of the outer splint 42, and the hinge point of the hinge is defined as the fourth hinge point 422, and the other sides of the two second connecting rods 421 extend from the same side of the outer splint and are hinged to the first connecting rod 411, between the outer splint 42 and the adjacent inner splint 41, the middle position of the second connecting rod 421 is hinged to the second hinge point 413 of the first connecting rod 411, and between the outer splint 42 and the spaced inner splint 41, the side position of the second connecting rod 421 is hinged to the third hinge point of the first connecting rod 411.

[0037] On the side of each splint 4 away from the center of the sponge conveyor belt 1, there is also a movable guide seat that cooperates with each first connecting rod 411 and the second connecting rod 421. There are two movable guide seats, which are located on the upper and lower sides of the splint 4 respectively. A movable roller 415 that moves up and down in the movable guide seat is also installed at the third hinge point of the first connecting rod 411. At the third hinge point, if there are two first connecting rods 411 hinged to each other or a first connecting rod 411 and a second connecting rod 421 are hinged, then a movable roller 415 is shared.

[0038] The movable guide seat includes a pair of clamping plates 6 arranged side by side on a clamping plate. An annular groove is defined in the middle of the outer circumferential wall of the movable roller 415. A gap is left between the two clamping plates 6 to accommodate the movable roller 415. The gap between the two clamping plates 6 is smaller than the diameter of the movable roller 415 and not smaller than the diameter of the movable roller 415 at the location of the annular groove. The design of the movable guide seat utilizes the cooperation of the two clamping plates 6 and the annular groove on the movable roller 415 to guide the movable roller 415 in its upward and downward movement, preventing the movable roller 415 from deviating and providing a good foundation for the subsequent smooth opening and closing of the clamping plates 6.

[0039] In this embodiment, the two card plates 6 are integrated on the same card plate seat 61, and the card plate seat 61 is fixed on the splint 4. The cross-section of the card plate 6 is in an inverted L shape, so that an inverted T-shaped movable cavity can be formed between the two card plates 6 and the card plate seat 61 to accommodate the insertion and movement of the movable roller 415.

[0040] An arc chamfer is also provided on one side of the clamping plate 6 close to the center direction of the clamping plate 4. The design of the arc chamfer is to facilitate the movable roller 415 to be smoothly inserted into the gap between the two clamping plates 4, thereby facilitating the installation of the movable roller 415.

[0041] In each movable guide seat, an upper limit plate 52 is further provided on the upper side of the movable guide seat located on the upper side, and is located on the upper side of the clamping plate 6. A lower limit plate 53 is further provided on the lower side of the movable guide seat located on the lower side, and is located on the lower side of the clamping plate 6. The design of the upper limit plate 52 and the lower limit plate 53 is used to provide a hard limit for the upward or downward travel of the movable roller 415, thereby preventing the driving assembly from continuing to drive the clamping plate 4 to close after the clamping plate 4 is fully closed, which may cause damage to the clamping plate 4 or the components of the driving assembly.

[0042] Among the two outer plywoods 42, a driving assembly is further provided at the outer plywood 42 located on the discharge side of the sponge conveyor belt 1. The driving assembly includes a driving rack 5 installed on the inner plywood 41 and extending along the conveyor belt direction of the sponge conveyor belt 1. The driving rack 5 is directly fixed on the inner plywood 41 and drives the inner plywood 41 to move synchronously. A driving gear meshing with the driving rack 5 is also provided on the outer plywood 42. The driving gear is driven to rotate by the motor 51 installed on the outer plywood 42, and realizes the horizontal movement of the driving rack 5, thereby driving the outer plywood 42 to move horizontally, and then the cooperation of the first connecting rod 411 and the second connecting rod 421 is used to realize the simultaneous separation or closing of all the plywoods 4.

[0043] Working principle: In the initial state, each splint 4 is in a closed state, such as Figure 3As shown, in this state, it is suitable for clamping some sponges of relatively small sizes.

[0044] When the length of the sponge to be clamped is relatively long, the motor 51 works to drive the driving gear to rotate, and the rotation of the driving gear will drive the outer splint 42 to move synchronously. When the outer splint 42 is translated, it will drive the two second connecting rods 421 of the second connecting member to swing and contract along the fourth hinge point, so that the opening of the V-shaped opening formed by the two second connecting rods 421 becomes smaller, and the swing of the two second connecting rods 421 will drive the first connecting rod 411 connected thereto to swing, and finally realize the synchronous swing of all the first connecting rods 411 and the second connecting rod 421, so that all the splints 4 are separated from each other, forming a V-shaped opening as shown in FIG. Figure 5 The state shown is suitable for clamping longer sponges.

[0045] When it is necessary to clamp the small-sized sponge again, the motor 51 can be reversed.

[0046] The automatic telescopic sponge supporting device of the present invention realizes the adjustment of the length of the entire clamping plate by separating or closing multiple clamping plates 4, so as to adjust according to the size of different sponges to better clamp and support the sponge. It can be suitable for clamping sponges of various specifications, and subsequently the length of the sponge can be detected by adding a sensor to the outer clamping plate 42 or the inner clamping plate 41, so as to realize automatic telescopic adjustment of the length of the clamping plate according to the length of different sponges.

[0047] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
