Description

Technical Field

This results in a large overall footprint for the claw-type sheet-joining machine, essentially requiring two sets of sheet-joining devices to complete one action, leading to a complex structure and high energy consumption.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] Example

[0023] like Figure 1 and Figure 2 As shown, in this embodiment, the receiving device 4 includes: a receiving rack 41, a crank-slider mechanism 42, a horizontal moving support plate 43, a vertical moving support plate 44, a receiving assembly 45, a vertical moving connector 46, a pulley assembly 47, a horizontal drive unit 48, and a vertical drive unit 49.

[0024] The receiving rack 41 has a horizontal sliding groove 41a, in which the slider 42a of the crank-slider mechanism 42 slides horizontally. The horizontal moving support plate 43 is fixedly connected to the slider 42a of the crank-slider mechanism 42 and slides horizontally on the receiving rack 41. A discharge tray assembly 41c is also fixedly mounted on the receiving rack 41.

[0025] To improve the stability of the horizontal support plate 43 during horizontal movement, in this embodiment, two horizontal sliders 43a are fixed on the horizontal moving support plate 43; the receiving rack 41 has two horizontal slide rails 41b; the horizontal sliders 43a can slide horizontally on the corresponding horizontal slide rails 41b. Furthermore, slider 42a is located between the two horizontal sliders 43a.

[0026] The vertically movable support plate 44 is slidably connected to the horizontally movable support plate 43, and can slide vertically on the horizontally movable support plate 43. In this embodiment, a vertical slide rail 43b is fixed on the horizontally movable support plate 43, and a vertical slider 44a is provided on the vertically movable support plate 44; the vertical slider 44a can slide vertically on the vertical slide rail 43b, thereby realizing the slidable connection between the vertically movable support plate 44 and the horizontally movable support plate 43.

[0027] The receiving assembly 45 is fixed on the vertically movable support plate 44. In this embodiment, the receiving assembly 45 includes two horizontal receiving rods.

[0028] In this embodiment, the pulley assembly 47 includes a driving pulley 47a, a driven pulley 47b, and a transmission belt 47c. The driving pulley 47a and the driven pulley 47b are vertically arranged on the receiving frame 41, and the transmission belt 47c is sleeved on the driving pulley 47a and the driven pulley 47b, with the direction of movement of the straight position of the transmission belt 47c being vertical.

[0029] One side of the vertical moving connector 46 is fixed to the transmission belt 47c of the pulley assembly 47, and the other side is fixedly connected to the vertical moving support plate 44. In order to improve the stability of the vertical movement of the vertical moving connector 46, the vertical moving connector 46 is also vertically slidingly connected to the back of the receiving rack 41 through a slide rail and a slider.

[0030] In this embodiment, both the horizontal drive unit 48 and the vertical drive unit 49 are motors. The horizontal drive unit 48 rotates in both directions, driving the slider 42a of the crank-slider mechanism 42 to slide horizontally within the horizontal sliding groove 41a, thereby causing the horizontal moving support plate 43, the vertical moving support plate 44, and the receiving assembly 45 to move horizontally. The vertical drive unit 49 rotates in both directions, driving the transmission belt 47c to move vertically, thereby causing the vertical moving connector 46, the vertical moving support plate 44, and the receiving assembly 45 to move vertically.

[0031] like Figure 3 As shown, this embodiment also provides a claw-type sheet-forming and sheet-forming device that applies the above-mentioned receiving device, including: a conveying device 1, a claw-type sheet-forming device 2, a receiving port 3, and two sheet-forming devices 4.

[0032] like Figure 4 As shown, in this embodiment, the conveying device 1 is a negative pressure suction conveying device, including an active roller group 11, a suction belt 12, a suction pipe 13, a driven roller group 14, a suction groove 15, a negative pressure gauge 16, and a detection component 17.

[0033] The suction belt 12 is fitted onto the active roller group 11 and the driven roller group 14; the suction pipe 13 is connected to the suction groove 15, and provides negative pressure to the suction groove 15 through the suction pipe 13; a section of the conveying path of the suction belt 12 is close to the lower surface of the suction groove 15 so that the product can be smoothly adsorbed on the suction belt 12 for transport; the detection component 17 is installed on the suction groove 15 to monitor the arrival of the product in real time, and the negative pressure gauge 16 can control the negative pressure value of the entire negative pressure suction system, thereby better transporting the product.

[0034] like Figure 5 and Figure 6As shown, in this embodiment, the claw-type sheet-beating device 2 includes: two sheet-beating motors 21a and 21b, two sheet-beating proximity switches 22a and 22b, two sheet-beating shafts 23a and 23b, two pairs of sheet-beating plates 24a and 24b, a sheet-blocking motor 25, a sheet-blocking proximity switch 26, a sheet-blocking shaft 27, and a sheet-blocking plate 28.

[0035] Two sheet-beating proximity switches 22a and 22b are located on both sides of the conveying device 1, above the receiving port 3. When the product is conveyed by the conveying device 1 to the area above the receiving port 3, the sheet-beating proximity switches 22a and 22b are triggered, starting the sheet-beating motors 21a and 21b. The two sheet-beating motors 21a and 21b drive the two corresponding sheet-beating shafts 23a and 23b to rotate symmetrically inward. The two pairs of sheet-beating plates 24a and 24b are fixed on the corresponding two sheet-beating shafts 23a and 23b, respectively. As the sheet-beating shafts 23a and 23b rotate in opposite directions, a downward force is applied to both sides of the product, causing the product to tend to move downward.

[0036] Meanwhile, the baffle shaft 27 is set perpendicular to the conveying direction of the conveying device 1; the baffle 28 is fixed on the baffle shaft 27; when the conveying device 1 conveys the product to the striking position, the baffle proximity switch 26 is triggered, the baffle motor 25 is started, the baffle motor 25 drives the baffle shaft 27 to rotate at a set angle, and drives the baffle 28 to block the product and stop moving forward, and cooperates with the striking plate to knock the product down.

[0037] like Figure 7 As shown in this embodiment, the receiving port 3 includes: a receiving bracket 31, a front baffle 32, a rear baffle 33, a left baffle 34, a right baffle 35, a left support plate 36, a right support plate 37, a left cylinder 38, and a right cylinder 39.

[0038] The front baffle 32, rear baffle 33, and receiving bracket 31 are adjustablely connected. The left baffle 34 and left support plate 36 are adjustablely connected; the right baffle 35 and right support plate 37 are adjustablely connected. In this embodiment, the front baffle 32, rear baffle 33, left baffle 34, and right baffle 35 are provided with elongated holes, which can adjust the size of the receiving port according to the size of the product.

[0039] The fixed end of the left cylinder 38 is fixed on the receiving bracket 31, and the telescopic end is fixedly connected to the left support plate 36; the fixed end of the right cylinder 39 is fixed on the receiving bracket 31, and the telescopic end is fixedly connected to the right support plate 37; the left cylinder 38 and the right cylinder 39 drive the left baffle 34 and the right baffle 35 to move closer and further away.

[0040] When the material is dropped, the left and right cylinders drive the left and right support plates to extend and receive the products stacked from the claw-type sheet-breaking device 2. After the product is received by the sheet-receiving device, the left and right cylinders drive the left and right support plates to retract.

[0041] In this embodiment, as Figure 3 As shown, two receiving devices 4 are symmetrically arranged on both sides of the receiving port 3. The vertical drive units 49 of the two receiving devices 4 drive the receiving assembly 45 to alternately move in height.

[0042] When the receiving component 45 of a receiving device 4 reaches the set highest position, the slider 42a of the crank slider mechanism 42 drives the receiving component 45 to move horizontally until it enters the receiving position of the receiving port 3 to receive the material; after receiving the material, the vertical drive unit 49 drives the receiving component 45 to move downward to the set lowest position, that is, the receiving component 45 falls onto the dropping slide assembly 41c.

[0043] Meanwhile, the receiving component 45 of another receiving device 4 is at the set lowest position, that is, after the receiving component 45 falls onto the material dropping slide assembly 41c; the slider 42a of the crank slider mechanism 42 drives the receiving component 45 to move horizontally until it completely exits the receiving port 3, and then the vertical drive unit 49 drives the receiving component 45 to move downward to the set highest position, waiting for the next receiving; the two receiving devices 4 alternately reciprocate.

[0044] Working process of claw-type sheet forming and splicing equipment:

[0045] The conveying device 1 uses negative pressure suction to adsorb the product onto the suction belt 12 and transport the product to the claw-type sheet-making device 2.

[0046] When the product triggers the two plate-beating proximity switches 22a and 22b and the plate-stopping proximity switch 26, the plate-stopping plate 28 blocks the product and stops it from moving forward. The two pairs of plate-beating plates 24a and 24b rotate in opposite directions, giving the product a downward force on both sides. The product tends to move downward and is knocked down to the receiving port 3.

[0047] When the material is being fed, the left and right cylinders of the receiving port 3 drive the left and right support plates to extend and receive the products stacked down from the claw-type sheet-breaking device 2.

[0048] When the product reaches the set quantity, the slider 42a of the crank-slider mechanism 42 corresponding to the receiving component 45, which is waiting at the set highest position, drives the receiving component 45 to move horizontally until it enters the receiving position of the receiving port 3 to receive the product. After receiving the product, the left and right cylinders of the receiving port 3 drive the left and right support plates to retract respectively, and the product falls onto the receiving component 45. The vertical drive unit 49 drives the receiving component 45 to move downward to the set lowest position, that is, the receiving component 45 falls onto the dropping slide assembly 41c.

[0049] Meanwhile, after the receiving component 45 of another receiving device 4 falls from the lowest position onto the material dropping plate assembly 41c, the slider 42a of the crank-slider mechanism 42 drives the receiving component 45 to move horizontally until it completely exits the receiving port 3. Then, the vertical drive unit 49 drives the receiving component 45 to move downward to the set highest position, ready for the next receiving. The two receiving devices 4 alternately reciprocate.

[0050] The embodiments described above are merely some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
