[0043] The present invention is further described in detail below in conjunction with embodiments so that those skilled in the art can implement the invention with reference to the description.

[0044] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0045] like Figure 1-9 As shown, a clamping device with automatic material discharge function of this embodiment includes: a base plate 1, a slide rail 10 arranged on the base plate 1, a slider 11 slidably arranged on the slide rail 10, a mounting frame 2 fixedly connected to the slider 11, a motion conversion block 3 arranged on the mounting frame 2, a push rod 4 connected to the first end 30 of the motion conversion block, a driving assembly 5 for driving the push rod 4 to perform horizontal linear motion, a pressure head assembly 6 slidably arranged on the mounting frame 2 in a vertical direction, a pusher assembly 7 arranged on the pressure head assembly 6, a clamping workbench 8 below the pressure head assembly 6, and a material conveying device 9 arranged on the side of the clamping workbench 8;

[0046] The second end 31 of the motion conversion block is in contact with the pressure head assembly 6. The motion conversion block 3 is used to convert the horizontal linear motion of the push rod 4 into the vertical linear motion of the pressure head assembly 6 to compact the material on the compacting workbench 8.

[0047] The material pushing assembly 7 is used to move the compacted material from the compacting workbench 8 to the material conveying equipment 9 so as to transport the compacted material outward.

[0048] The clamping device with automatic discharge function of the present invention can be mainly used to compress materials, and push the compressed materials into the conveying equipment to be transported to the next working position. The functions it needs to have are: 1. Compress the materials transported to the clamping workbench 8; 2. Transport the compressed materials from the clamping workbench 8 to the material conveying equipment 9. The present invention is particularly used for compressing block or sheet materials to realize related process operations (such as packaging and embossing on products by compression, or further processing of products by compression, etc.). In these compression operations, the requirements for the pressure size are not high. For example, when laminating a product, the film needs to be applied to the surface of the product (such as picture albums, carton packaging, plastic shells, etc.), and then compressed, and then transported out after compression to achieve automatic discharge.

[0049] In the present invention, when compacting, the pressure head assembly 6 first moves from the side of the product 90 to directly above the product 90. During this process, the pusher assembly 7 can exert a certain pushing effect on the product 90, so as to facilitate the product 90 to be in place; then the pressure head assembly 6 squeezes the product 90 downward again. After compacting, the pressure head assembly 6 first resets upward and then withdraws from the side. During the withdrawal process, the pusher assembly 7 can push the product 90 to the material conveying equipment 9, so as to realize the external transportation of the compacted product 90. Thus, a driving assembly 5 can realize the compaction of the material while also transporting the compacted product 90 to the material conveying equipment 9, which is efficient and convenient, simplifies the equipment, and saves energy. In addition, before and after compaction, there is no obstruction above the product 90, which is convenient for operation and observation. The following provides more specific embodiments to further illustrate the present invention.

[0050] In a preferred embodiment, a stopper 12 for limiting the sliding position of the slider 11 is provided on the bottom plate 1. The mounting frame 2 includes a horizontal mounting plate 20 fixed to the slider 11 and a vertical mounting plate 21 fixed to the horizontal mounting plate 20; the motion conversion block 3 is L-shaped, the middle part of which is rotatably connected to the upper end of the vertical mounting plate 21 through a first rotating shaft 32, and the first end 30 of the motion conversion block is rotatably connected to the first end 40 of the push rod through a second rotating shaft 33.

[0051] The driving assembly 5 includes a motor 50 , a screw rod 51 drivingly connected to the output shaft of the motor 50 , and a nut 52 sleeved on the screw rod 51 , and the second end 41 of the push rod is fixedly connected to the nut 52 .

[0052] Among them, the pressure head assembly 6 includes a guide rod 60 fixedly connected to the horizontal mounting plate 20, a sliding sleeve 61 which can be arranged on the guide rod 60 along the vertical direction, a connecting plate 62 fixedly connected to the bottom of the sliding sleeve 61, a pressure head 63 fixedly connected to the other end of the connecting plate 62, and a first spring 64 which is sleeved on the guide rod 60 and is located between the sliding sleeve 61 and the horizontal mounting plate 20; the second end 31 of the motion conversion block contacts the top surface of the sliding sleeve 61 to apply downward pressure to the sliding sleeve 61.

[0053] In the present invention, the pressing head assembly 6 is driven by a motor 50 to first move horizontally to the left, the pressing head 63 moves laterally from the product 90 to a position directly above the product 90, and then the pressing head 63 moves downward to perform extrusion.

[0054] Specific:

[0055] 1) The motor 50 drives the screw rod 51 to rotate, and the nut 52 and the screw rod 51 are threadedly matched to move horizontally to the left, driving the push rod 4 to move to the left. The push rod 4 is connected to the slider 11. At this time, the first spring 64 has an upward elastic force to limit the downward movement of the sliding sleeve 61, so that the push rod 4 will first drive the slider 11 to slide to the left until the left end of the slider 11 contacts the stopper 12, and the movement of the slider 11 is stopped. At this time, the pressure head 63 moves to the top of the product 90, as shown in FIG. Figure 1 and 2 Status shown;

[0056] 2) Under the action of the motor 50, the push rod 4 continues to move to the left, the slider 11 remains fixed, and the first end 30 of the motion conversion block rotates counterclockwise around the first rotating shaft 32, driving the second end 31 of the motion conversion block to rotate counterclockwise, so that the second end 31 of the motion conversion block exerts downward pressure on the sliding sleeve 61, and the sliding sleeve 61 drives the pressing head 63 to move downward, compressing the first spring 64, and the pressing head 63 exerts a squeezing force on the product 90 below it to achieve compaction;

[0057] 3) After the clamping is completed, the motor 50 reverses, driving the push rod 4 to move to the right, and the second end 31 of the motion conversion block rotates clockwise and lifts upward, the pressure on the sliding sleeve 61 disappears, and under the elastic force of the first spring 64, the sliding sleeve 61 drives the pressure head 63 to move upward and return to its original position; the push rod 4 continues to move to the right, and after the first spring 64 is compressed to the shortest, the motion conversion block 3 can no longer rotate, and the push rod 4 pulls the slider 11 to slide to the right to achieve horizontal resetting.

[0058] Among them, the compression displacement push rod 4 and the motion conversion block 3 are enlarged, which is more conducive to accurately adjusting the size of the pressure.

[0059] In a further preferred embodiment, the bottom surface of the second end 31 of the motion conversion block is pivotally connected with a pressure ball 34 (a roller may also be used) for contacting the top surface of the sliding sleeve 61. The pressure ball 34 can be rotatably connected to the bottom surface of the second end 31 of the motion conversion block through a rotating shaft. When pressing, the second end 31 of the motion conversion block rotates, and the pressure ball 34 presses the upper surface of the sliding sleeve 61. The pressure ball 34 moves to the left and moves downward, and the pressure ball 34 rolls relative to the upper surface of the sliding sleeve 61, thereby reducing the horizontal friction between the pressure ball 34 and the upper surface of the sliding sleeve 61, that is, it can reduce invalid friction, facilitate the rotation of the second end 31 of the motion conversion block, and reduce the wear of the mechanism.

[0060] A spring mounting plate 22 is also provided at the top of the vertical mounting plate 21, and a second spring 23 is connected to the spring mounting plate 22, and the other end of the second spring 23 is connected to the second end 31 of the motion conversion block. The second spring 23 exerts an upward pulling force on the second end 31 of the motion conversion block. When pressed, the second spring 23 is stretched. After the pressing is completed, the push rod 4 moves to the right, and the motion conversion block 3 rotates clockwise. The second spring 23 exerts an upward pulling force on the second end 31 of the motion conversion block to facilitate the reset of the motion conversion block 3.

[0061] Reference Figure 8 , a pressing groove 80 for placing materials is provided on the table top of the pressing workbench 8, and a receiving groove 81 for receiving the pushing assembly 7 is provided on the side of the pressing groove 80. The right side of the pressing groove 80 has an opening for outputting the pressed product 90. When the product 90 is put in, it can be put into the pressing groove 80 from directly above, or it can be put in from the opening on the right. It should be understood that the receiving groove 81 is used to receive the pushing assembly 7 (the pushing assembly 7 is smaller than the product 90), which is smaller than the pressing groove 80 and larger than the product 90. The product 90 can only be put into the pressing groove 80 and cannot enter the receiving groove 81 to the left. Among them, when the product 90 moves to the leftmost end, it contacts the left inner wall of the pressing groove 80. At this time, the surface product 90 reaches the working position. When the pressing head 63 also reaches the working position, the product 90 is directly below the pressing head 63. Further, refer to Fig. 9 A transition plate 82 is also provided on the compacting workbench 8, and the other end of the transition plate 82 is connected to the material conveying device 9, and the transition plate 82 is inclined toward the material conveying device 9, and the compacted product 90 slides onto the material conveying device 9 through the transition plate 82. The material conveying device 9 can be a conventional belt conveyor or a roller conveyor.

[0062] The function that the pusher assembly 7 needs to realize is: when the pressure head 63 moves from right to left to above the product 90, the pusher assembly 7 moves from the right side of the product 90 over the product 90 to the left side of the product 90, and finally enters the containing groove 81, and in this process, the bottom end of the pusher assembly 7 slides over the surface of the product 90 and exerts a certain force to push the product 90 to the left, so that the product 90 is close to the left inner wall of the pressing groove 80 to reach the working position, and the product 90 is just below the pressure head 63. After the pressing is completed, the pressure head 63 is first reset vertically upward, and then reset horizontally to the right. During the horizontal reset process, the pusher assembly 7 drives the product 90 to move to the right, detaches from the right side of the pressing groove 80, and moves to the material conveying device 9 on the right side of the pressing groove 80. Specifically, this is realized by the following structure in this embodiment. The push assembly 7 includes a mounting block 70 connected to the side wall of the lower end of the pressure head 63, a movable baffle 71 rotatably connected to the bottom of the mounting block 70, a limit baffle 72 fixed to the bottom of the mounting block 70 and located on the side wall of the movable baffle 71, and a third spring 73 connected between the limit baffle 72 and the movable baffle 71. Further preferably, the movable baffle 71 is a retractable baffle, which includes an outer plate 710 rotatably connected to the bottom of the mounting block 70, a slot 711 provided in the outer plate 710, and an inner plate 712 retractably inserted in the slot 711. When the movable baffle 71 is in a vertical state, under the action of gravity, the inner plate 712 slides downward to the bottom, and the bottom end of the inner plate 712 contacts the bottom surface of the pressing groove 80 or the receiving groove 81.

[0063] The working principle of the pusher assembly 7 is:

[0064] 1. In the process of the pressing head 63 moving from right to left to above the product 90: the left side of the lower end of the inner plate 712 of the movable baffle 71 contacts the left side of the product 90, the third spring 73 has a pulling force to the left on the inner plate 712, and the inner plate 712 has a pushing force to the left on the product 90, so that the product 90 approaches the left inner wall of the clamping groove 80 to reach the working position; the pressing head 63 continues to move to the left, and the rightward resistance received by the inner plate 712 is greater than the pulling force of the third spring 73, the movable baffle 71 rotates counterclockwise as a whole, thereby tilting (as shown in states 3 and 4), and then the bottom end of the inner plate 712 slides to the left from the upper surface of the product 90 until it enters the receiving groove 81, the movable baffle 71 returns to verticality, and the bottom end of the inner plate 712 contacts the bottom surface of the receiving groove 81, the pressing head 63 moves to the left to the working position and stops moving horizontally, at which time the pressing head 63 is directly above the product 90 (as shown in states 1 and 2);

[0065] 2. The pressure head 63 moves downward vertically to squeeze the product 90. After the squeezing is completed, the pressure head 63 first resets vertically upward, and then resets horizontally to the right. When resetting horizontally, the right side of the bottom end of the inner plate 712 contacts the left side of the product 90. At this time, due to the blocking effect of the limit baffle 72, the movable baffle 71 cannot rotate clockwise, so that the rightward movement of the movable baffle 71 drives the product 90 to move to the right. The product 90 slides onto the material conveying equipment 9 through the inclined transition plate 82 and is transported to the next station to realize automatic discharge. Among them, since the inner plate 712 can slide up and down relative to the outer plate 710, when the movable baffle 71 is vertical, the bottom end of the inner plate 712 can always contact the bottom surface of the pressing groove 80 or the receiving groove 81, which will be lower than the upper surface of the product 90, so that it can generate thrust on the product 90 from the side.

[0066] Furthermore, a limit strip 713 is connected to the inner wall at the port of the slot 711, and a clamping strip 714 is connected to the side wall of the inner end of the inner plate 712; the setting of the limit strip 713 and the clamping strip 714 can prevent the inner plate 712 from being separated from the slot 711 of the outer plate 710, referring to Figure 6 and 7 When the inner plate 712 slides down to the bottom of the slot 711, the clamping bar 714 presses on the limiting bar 713, so that the inner plate 712 will not slide down further.

[0067] In a further preferred embodiment, a ball 715 is pivotally connected to the outer end of the inner plate 712. When the inner plate 712 slides to the left on the upper surface of the product 90, the ball 715 rolls in contact with the upper surface of the product 90, which can reduce friction, facilitate smooth sliding of the inner plate 712, and prevent the inner plate 712 from scratching the surface of the product 90.

[0068] The overall working process of the present invention is:

[0069] 1. Horizontal positioning: The motor 50 works, and the push rod 4 drives the slider 11 and the pressure head assembly 6 to move to the left, so that the pressure head 63 reaches the top of the product 90. During this process, the movable baffle 71 pushes the product 90 to the leftmost side, so that the product 90 is close to the left inner wall of the pressing groove 80, and the product 90 is in place; that is, Figure 3 to Figure 1 Status;

[0070] 2. Vertical extrusion: The push rod 4 continues to move, which is converted into vertical downward movement of the pressure head 63 through the motion conversion block 3 to extrude the product 90;

[0071] 3. Reset: The motor 50 reverses, the pressure head 63 moves upward to reset vertically, and then moves rightward to be removed from above the product 90. During this process, the product 90 is pushed to the material conveying device 9 on the left by the movable baffle 71, so that the product 90 is conveyed to the next station to realize automatic discharge, that is, Figures 1 to 9 status.

[0072] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the implementation modes. They can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to specific details.
