[0036] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0037] like Figure 1-4 As shown, the utility model provides a plastic product cutting device, which includes: an operating table 1, a feeding mechanism 2, a material receiving box 3 and a cutting machine 6;

[0038] A cutting machine 6 is horizontally and movably provided at one end of the operating table 1 and can be moved along its width direction to cut the plastic products horizontally placed on its upper end. A feeding mechanism 2 is also provided at the upper end of the operating table 1 and can feed the plastic products toward the cutting machine 6. A receiving box 3 is provided below the cutting machine 6 and can collect the cut plastic products and waste. A screening net 4 is fixedly and horizontally inside the vibrating receiving box 3 to screen the waste and the cut plastic products. A pressing plate 10 that can rest against the plastic products is horizontally and movably provided above the operating table 1 next to the cutting machine 6.

[0039] In the above scheme, when in use, the plastic product to be cut is placed horizontally on the upper surface of the operating table 1, such as Figure 1 and Figure 2 As shown, the feeding mechanism 2 can push the plastic product to be cut toward the cutting machine 6 to automatically feed the cutting machine 6, and move the plastic product to a suitable position according to the required cutting length, such as Figure 1 As shown, after the plastic product to be cut is pushed to the end of the operating table 1 to be exposed to the required cutting length, the pressing plate 10 is lowered in the vertical direction until it is against the plastic product to fix the plastic product to prevent the plastic product from shifting during the cutting process and affecting the cutting effect. After the plastic product is fixed, the cutting machine 6 is started to move from one side of the plastic product to the other side along the width direction of the operating table 1 to cut the plastic product. Through the coordinated use of the feeding mechanism 2 and the cutting machine 6, the function of automatic feeding is realized. During the entire cutting process, no staff participation is required, which saves time and effort and improves work efficiency.

[0040] During the cutting process, the cut plastic products and the waste generated by the cutting fall into the receiving box 3 under the action of their own gravity. The vibration generated by the receiving box 3 can automatically screen the cut plastic products and the waste, so that the waste passes through the screening net 4 and falls to the bottom of the receiving box 3 while the cut plastic products fall on the screening net 4, thereby realizing the automatic screening effect, so that during the cutting process, the cut plastic products and the waste generated during the cutting process can be classified and collected, preventing the waste generated during the cutting process from being scattered on the ground and requiring staff to clean it up later.

[0041] In a preferred embodiment of the present utility model, the feeding mechanism 2 comprises: a feeding shaft 201, a belt roller 202, a belt 203 and a feeding plate 204; wherein,

[0042] At least two feed shafts 201 are arranged inside the operating table 1 in a spaced and horizontally rotatable manner, and a belt roller 202 is coaxially fixedly arranged on each of the feed shafts 201, and all the belt rollers 202 are connected together by a belt 203. A guide window 20 connected to the interior of the operating table 1 is provided at the upper end, and a feed plate 204 is vertically fixed on the belt 203, which partially extends from the guide window 20 and abuts against one end of the plastic product to push the plastic product toward the cutting machine 6.

[0043] In the above scheme, the end of any one of the feeding shafts 201 extends out from the interior of the operating table 1 and is coaxially connected to the feeding motor horizontally fixed on the operating table 1 through a coupling to provide power for the feeding mechanism 2.

[0044] When in use, the feeding shaft 201 is driven to rotate to drive the belt 203 to run, and the belt 203 can drive the feeding plate 204 to push the plastic product toward the cutting machine 6 during the running process, thereby realizing the process of automatic feeding.

[0045] There are two ways to realize the reset of the feeding plate 204 after it moves to the cutting machine 6. One of them is to continue to rotate the feeding shaft 201 to drive the belt 203 to continue to drive the feeding plate 3 from the top of the operating table 1 to the inside of the operating table 1 and continue to move horizontally to the end away from the cutting machine 6, and reset to its initial position as the belt 203 runs, that is, Figure 2 Another reset method is to rotate the feeding shaft 201 in the reverse direction to drive the belt 203 to run in the reverse direction, and during the reverse movement, the feeding plate 204 can be driven to move horizontally in the reverse direction to the initial position.

[0046] In a preferred embodiment of the present utility model, the feeding mechanism 2 is further provided with a power rod 9 for providing power for the receiving box 3 to vibrate; wherein,

[0047] One end portion of the horizontally movable material receiving box 3 extends to the interior of the operating table 1 and is spaced and vertically fixed with at least two wedge blocks 13. The feeding shaft 201 located directly above the two wedge blocks 13 is vertically fixed with a plurality of power rods 9 that are evenly spaced along its circumferential direction and can intermittently push the corresponding wedge blocks 13 to move toward the fixed plate. A plurality of fixing rods 14 are evenly and horizontally fixed on the material receiving box 3 between the two wedge blocks 13. A fixing plate is vertically fixed inside the operating table 1, and the fixing plate is horizontally penetrated with guide holes that correspond to all the fixing rods 14 one by one and are for them to pass through. A spring 15 is sleeved on each of the fixing rods 14 between the material receiving box 3 and the fixed plate.

[0048] In the above scheme, if Figure 2 As shown, the dotted line in the figure represents the movement trajectory of the power rod. When the feed shaft 201 is rotating, the multiple power rods 9 adapted to the two wedge blocks 13 can be in gap contact with the wedge blocks 13 of the material receiving box 3 during the rotation of the feed shaft 201, and push the wedge blocks 13 toward the fixed plate during the continuous rotation. The material receiving box 3 can compress each spring 15 on each fixed rod 14 during the movement toward the fixed plate, so that each spring 15 is in a compressed state. When the power rod 9 is separated from the wedge blocks 13, the material receiving box 3 can move in the opposite direction in the horizontal direction under the action of the multiple springs 15.

[0049] Therefore, with the coordinated use of the spring 15 and the power rod 9, whenever the power rod 9 drives the material receiving box 3 to move through the wedge block 13, it can drive the material receiving box 3 to reciprocate in the horizontal direction, so that the material receiving box 3 vibrates in the horizontal direction, thereby screening the cut plastic products and waste chips, so that the waste chips fall onto the bottom of the material receiving box 1 through the screening net, thereby realizing the function of separating the plastic products and waste chips.

[0050] In a preferred embodiment of the present utility model, a roller is rotatably provided at the end of each power rod 9, and an escape opening is opened on the top of the operating platform 1 for each power rod 9 to operate.

[0051] In a preferred embodiment of the present invention, a plurality of rollers 16 capable of contacting the ground are evenly and rotatably provided at the bottom end of the receiving box 3 away from the operating table 1 .

[0052] In the above scheme, the roller 16 is used to support the material receiving box 3 so that it remains horizontal during its reciprocating movement. At the same time, the roller 16 is used to convert the sliding friction between the material receiving box 3 and the ground into rolling friction, so as to reduce the friction between it and the ground, thereby extending its service life.

[0053] In a preferred embodiment of the present invention, the cutting device further comprises a driving mechanism 7 for driving the cutting machine 6 to move along the width direction of the operating table 1, wherein the driving mechanism 7 comprises: a screw rod 701, a slider 702 and a motor box 703; wherein,

[0054] A bracket 12 is vertically fixed above the end of the operating table 1, and vertical plates are vertically fixed at both ends below the bracket 12 located next to the operating table 1, and a screw rod 701 is horizontally and rotatably arranged between the two vertical plates. A slider 702 that can move along its axis is threadedly fixed on the screw rod 701, and a motor box 703 is fixed at the bottom end of the slider 702. The cutting motor of the cutting machine 6 is horizontally fixed inside the motor box 703, and the output shaft portion of the cutting motor extends from the motor box 703. The cutting knife of the cutting machine 6 is coaxially fixed on its output shaft.

[0055] In the above scheme, a guide rod 8 is fixedly arranged in parallel between the two vertical plates located below the screw rod 701, and a guide hole is horizontally penetrated on the slider 702 for the guide rod 8 to pass through, so that the cutting machine 6 can be smoothly and reliably moved horizontally and linearly along the width direction of the operating table 1 through the coordinated use of the guide rod 8 and the guide hole on the slider 702.

[0056] In addition, a driving motor is horizontally fixed on any one of the vertical plates, and the output shaft of the driving motor is coaxially connected to the end of the screw rod 701 through a coupling to drive the screw rod 701 to rotate alternately in forward and reverse directions, thereby driving the slider 702 to drive the cutting machine 6 to move back and forth in the horizontal direction of the width of the operating table 1 to cut the plastic products on the operating table 1.

[0057] In a preferred embodiment of the present invention, the pressing plate 10 is assembled on the bracket 12 in a liftable manner through a longitudinal cylinder 11; wherein,

[0058] At least two longitudinal cylinders 11 are spaced apart and vertically fixed on the top of the bracket 12 , and the free ends of the piston rods of the two longitudinal cylinders 11 are respectively fixed on the pressing plate 10 .

[0059] In the above scheme, when in use, by driving the piston rod of the longitudinal cylinder 11 to extend from or retract into its cylinder portion, the pressing plate 10 can be driven to rise and fall in the vertical direction, so that the pressing plate 10 is lowered to rest against the plastic product, so as to avoid the plastic product being offset during the cutting process and reducing the cutting effect.

[0060] In addition, if Figure 1 As shown, the side wall of the bracket 12 is provided with an avoidance hole for the plastic products to pass through, so that the plastic products pass through the bracket 12 and move toward the cutting machine 6 through the feeding mechanism 2 to realize the automatic feeding function.

[0061] In addition, the bracket 12 located above the plastic product is fixed with a fan (not shown in the figure) that can blow the waste chips generated during the cutting process toward the receiving box 3. The fan can blow the waste chips generated during the cutting process away from the end of the operating table 1 and drop them into the receiving box 3, thereby preventing the waste chips from falling onto the operating table 1.

[0062] In a preferred embodiment of the present invention, two clamping plates 5 which are close to each other to clamp the plastic product are movably provided at the upper end of the operating table 1 located on both sides of the plastic product.

[0063] In the above scheme, each time the plastic product is moved to a certain position, the two clamps 5 are moved closer to each other until they are against both sides of the plastic product to further clamp and fix the plastic product, thereby preventing the plastic product from shifting during the cutting process and affecting the cutting effect, and further improving the stability and reliability of clamping the plastic product.

[0064] In a preferred embodiment of the present invention, the cutting device further comprises a transverse cylinder 17 for driving the two clamping plates 5 to move closer to each other to clamp and fix the plastic product; wherein,

[0065] At least one transverse cylinder 17 is horizontally fixedly disposed on the upper end of the operating table 1 located beside each of the clamping plates 5 , and the free end of the piston rod of each of the transverse cylinders 17 is fixed on the corresponding clamping plate 5 .

[0066] In the above solution, by driving the piston rod of the transverse cylinder 17 to extend from or retract into the cylinder portion, the clamping plate 5 can be driven to move linearly and steadily in the horizontal direction.

[0067] In addition, in this embodiment, the longitudinal cylinder 11 and the transverse cylinder 17 are both existing technologies, so their specific structures and usage principles will not be repeated here, and their specifications, sizes and assembly positions can be appropriately selected according to actual usage.

[0068] In a preferred embodiment of the present utility model, the upper ends of the operating table 1 located on both sides of the transverse cylinder 17 are partially recessed inward to form two guide grooves 18, and the bottom ends of each of the clamping plates 5 are vertically fixed with guide sliders 19 which can extend into the two guide grooves 18 and be slidably connected thereto.

[0069] In the above solution, by using the guide slot 18 and the guide slider 19 in coordination, it can be ensured that the clamping plate 5 can move linearly and steadily in a horizontal direction.

[0070] In summary, the plastic product cutting equipment provided by the utility model overcomes the problem in the prior art that the cutting mechanism can only be raised and lowered in the vertical direction and does not have the function of horizontal movement. Therefore, during use, the staff needs to manually adjust the fixed plate to release the clamping and fixation of the plastic product, and push the plastic product toward the cutting mechanism to realize the loading function, and then manually adjust the position of the fixed plate to clamp and fix the moved plastic product, and repeat the above operations to complete the cutting operation of the entire plastic product. The entire operation process is time-consuming, labor-intensive, and reduces the work efficiency.

[0071] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, and these simple modifications all belong to the protection scope of the present invention.

[0072] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present utility model will not further describe various possible combinations.

[0073] In addition, various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
