Description

Technical Field

[0001] The utility model relates to the technical field of plastic processing, in particular to a plastic cutting and feeding device. Background Art

[0002] Plastic is a synthetic material widely used in the manufacture of various products. It has the characteristics of light weight, corrosion resistance, and strong plasticity. Plastic as a raw material is usually made into different plastic products. Among them, foam plastic is processed from plastic raw materials. Foam plastic often needs to be cut after molding. In order to meet usage needs, it is usually cut.

[0003] After searching, the Chinese patent "Feeding device for cutting foam plastics" authorization announcement number "CN 212385620 U" has a conveyor belt body and a suction cup. People place the foam plastic body on the suction cup to firmly fix it, thereby preventing the foam plastic body from shifting during the transportation process and affecting people's cutting work.

[0004] The above scheme can carry out the feeding operation, but because the foam plastic contains a large number of pores inside, when the foam plastic is fed, the suction cup is used to fix the foam plastic, which can achieve a certain limiting effect but cannot guarantee firm adsorption, resulting in the risk of the foam plastic shifting when moving, affecting the cutting effect. At the same time, after the cutting is completed, the staff needs to manually take out the cut foam plastic, affecting the cutting efficiency.

[0005] Therefore, a plastic cutting and feeding device is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a plastic cutting and feeding device in order to solve the above-mentioned problem. The device improves the problem that since the foam plastic contains a large number of pores inside, when the foam plastic is fed, it uses a suction cup to fix the foam plastic, which can achieve a certain limiting effect but cannot ensure firm adsorption, resulting in the risk of the foam plastic being offset when moving, affecting the cutting effect. At the same time, after the cutting is completed, the staff needs to manually take out the cut foam plastic, affecting the cutting efficiency.

[0007] The utility model achieves the above-mentioned purpose through the following technical scheme: a plastic cutting and feeding device, comprising: a mounting frame, the top end of the mounting frame is fixedly connected to a fixing frame, the bottom end of the fixing frame is installed with a resistance wire, the inner wall of the mounting frame is rotatably connected to two rollers, a conveyor belt is transmission-connected between the two rollers, one side of the mounting frame is fixedly connected to a motor, one end of one of the rollers passes through the mounting frame and is fixedly connected to the output shaft of the motor, and a fixing mechanism is arranged on the surface of the conveyor belt; wherein the fixing mechanism comprises a plurality of mounting plates fixedly connected to the surface of the conveyor belt, the inner wall of the mounting plate is rotatably connected to a bidirectional screw rod, the surface of the bidirectional screw rod is threadedly connected to a slider, and the top end of the slider passes through the mounting plate and is fixedly connected to the fixing plate.

[0008] Preferably, the fixing mechanism further comprises a circular ring fixedly connected to one end of the mounting plate, one end of the bidirectional screw is fixedly connected to a round rod, the other end of the round rod sequentially passes through the mounting plate and the circular ring, the surface of the circular rod is rotationally connected to the inner wall of the circular ring, the inner wall of the circular ring is fixedly connected to a coil spring, the other end of the coil spring is fixedly connected to the surface of the circular rod, the front end of the surface of the circular rod is fixedly connected to a trigger plate, and the surface of the mounting bracket is fixedly connected to a push rod. When the mounting plate drives the foam plastic to continue rotating after the foam plastic is cut, the push rod is used to push the trigger plate, which is conducive to the trigger plate driving the round rod and the bidirectional screw to rotate clockwise, so that the two fixing plates move away from each other to automatically release the fixation of the foam plastic, which is conducive to the foam plastic falling off automatically without the need for manual removal by the staff, thereby improving the cutting efficiency of the foam plastic, and after the foam plastic falls off automatically, the device is restored to its initial state under the action of the coil spring, thereby improving the practicality of the device.

[0009] Preferably, a mounting block is fixedly connected to the upper end of the surface of the circular ring, a first spring is fixedly connected to one side of the mounting block, the other end of the first spring is fixedly connected to the fixing block, and a limiting hole is provided at one side of the trigger plate. This is conducive to limiting the position of the round rod and the bidirectional screw rod, ensuring the firmness of the fixing plate when fixing the foam plastic, thereby improving the stability of the device during operation.

[0010] Preferably, the overall shape of the fixing plate is L-shaped, and the inner wall of the fixing plate is fixedly connected with a contact pad, which is conducive to better fixing the foam plastic and increases the stability of the foam plastic when being fixed.

[0011] Preferably, the top of the push rod is curved into a spherical shape, and one side of the trigger plate is curved into an arc shape. The shape of the top of the push rod is conducive to reducing the friction when pushing the trigger plate, and the shape of one side of the trigger plate is conducive to better squeezing the fixed block when the trigger plate rotates counterclockwise.

[0012] Preferably, the shape of the fixing block is half a sphere, and the shape of the inner wall of the limiting hole matches the shape of the fixing block. When the trigger plate rotates clockwise, the inner wall of the limiting hole is conducive to better squeezing the fixing block.

[0013] Preferably, a collection box is provided at the front end of the mounting frame, which is conducive to collecting the foam plastics after cutting.

[0014] Preferably, one end of the fixing block is fixedly connected to a limiting rod, and the other end of the limiting rod passes through the first spring and the mounting block in sequence, which is conducive to limiting the movement of the fixing block.

[0015] The beneficial effects of the utility model are:

[0016] 1. When fixing the foam plastic, the foam plastic is placed between the two fixing plates through the setting of the fixing mechanism. Under the action of the bidirectional screw and the coil spring, the two fixing plates fix the foam plastic, which improves the stability of the foam plastic when it moves, thereby ensuring the cutting effect of the foam plastic. At the same time, when the foam plastic is cut and the mounting plate drives it to continue to rotate, the trigger plate is pushed by the push rod, which is conducive to the trigger plate driving the round rod and the bidirectional screw to rotate clockwise, so that the two fixing plates move away from each other and automatically release the fixation of the foam plastic, which is conducive to the foam plastic falling automatically, without the need for manual removal by the staff, thereby improving the cutting efficiency of the foam plastic, and after the foam plastic falls automatically, the device is restored to the initial state under the action of the coil spring, thereby improving the practicality of the device;

[0017] 2. Under the action of the first spring, the fixing block is engaged with the limiting hole, which is beneficial to limiting the round rod and the bidirectional screw rod, ensuring the firmness of the fixing plate when fixing the foam plastic, thereby improving the stability of the device during operation.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] When implementing: Figure 1-5 As shown, a plastic cutting and feeding device comprises: a mounting frame 1, the top of the mounting frame 1 is fixedly connected to a fixing frame 2, the bottom of the fixing frame 2 is installed with a resistance wire 3, the inner wall of the mounting frame 1 is rotatably connected to two rollers 4, a conveyor belt 5 is transmission-connected between the two rollers 4, one side of the mounting frame 1 is fixedly connected to a motor 6, one end of one of the rollers 4 passes through the mounting frame 1 and is fixedly connected to the output shaft of the motor 6, and a fixing mechanism 7 is arranged on the surface of the conveyor belt 5; wherein the fixing mechanism 7 comprises a plurality of mounting plates 71 fixedly connected to the surface of the conveyor belt 5, the inner wall of the mounting plate 71 is rotatably connected to a bidirectional screw rod 72, the surface of the bidirectional screw rod 72 is threadedly connected to a slider 73, and the top of the slider 73 passes through the mounting plate 71 and is fixedly connected to a fixing plate 74.

[0026] The threads of the two sliders 73 connected to the bidirectional screw rod 72 are opposite to each other, so when the bidirectional screw rod 72 rotates, the two sliders 73 are driven to move toward each other.

[0027] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the fixing mechanism 7 also includes a circular ring 76 fixedly connected to one end of the mounting plate 71, one end of the bidirectional screw rod 72 is fixedly connected to a circular rod 75, the other end of the circular rod 75 passes through the mounting plate 71 and the circular ring 76 in sequence, the surface of the circular rod 75 is rotatably connected to the inner wall of the circular ring 76, the inner wall of the circular ring 76 is fixedly connected to a coil spring 77, the other end of the coil spring 77 is fixedly connected to the surface of the circular rod 75, the front end of the surface of the circular rod 75 is fixedly connected to a trigger plate 78, and the surface of the mounting frame 1 is fixedly connected to a push rod 79.

[0028] When the device is in the initial state, the trigger plate 78 is in a vertical state. When the foam plastic needs to be cut, the round rod 75 is rotated clockwise and the coil spring 77 is contracted. The rotation angle of the round rod 75 is less than 360 degrees. When the round rod 75 is rotated clockwise, the bidirectional screw rod 72 will be driven to rotate synchronously. At this time, the two sliders 73 will drive the two fixed plates 74 to move and move away from each other. The staff places the foam plastic between the two fixed plates 74. After the placement is completed, the round rod 75 is released. At this time, the coil spring 77 is released and reset and drives the round rod 75 to rotate counterclockwise, thereby driving the bidirectional screw rod 72 to rotate counterclockwise. At this time, the two fixed plates 74 are close to each other to clamp the foam plastic, thereby completing the fixation of the foam plastic. At the same time, the staff can start the motor 6 through the controller to drive one of the rollers 4 to rotate and drive the other roller 4 to rotate synchronously, so that the conveyor belt 5 drives the foam plastic to feed the material. The resistance wire 3 is electrically connected to a power supply. When the foam plastic is cut, the power supply is started by the controller to heat the resistance wire 3. When the foam plastic passes through the resistance wire 3, the resistance wire 3 can cut the foam plastic.

[0029] When the foam plastic is cut, the mounting plate 71 gradually rotates from a horizontal state to a vertical state, and the trigger plate 78 contacts the push rod 79 and pushes the trigger plate 78 to drive the round rod 75 and the bidirectional screw rod 72 to rotate clockwise, thereby moving the two fixing plates 74 away. At this time, the foam plastic will be released and automatically fall off, and in the process of the mounting plate 71 continuing to rotate, after the trigger plate 78 releases the contact with the push rod 79, the coil spring 77 drives the round rod 75, the trigger plate 78, and the bidirectional screw rod 72 to automatically reset.

[0030] like Figure 4 and Figure 5 As shown, a mounting block 710 is fixedly connected to the upper end of the surface of the ring 76, a first spring 711 is fixedly connected to one side of the mounting block 710, a fixing block 712 is fixedly connected to the other end of the first spring 711, and a limiting hole 713 is formed at one side of the trigger plate 78. The fixing block 712 is in the shape of a half sphere, and the inner wall shape of the limiting hole 713 matches the shape of the fixing block 712.

[0031] When the device is in the initial state, the fixing block 712 is engaged with the limiting hole 713 under the action of the first spring 711. When the round rod 75 is rotated clockwise and the trigger plate 78 is driven to rotate synchronously, the inner wall of the limiting hole 713 will squeeze the fixing block 712 out of the limiting hole 713 and cause the first spring 711 to contract. When the coil spring 77 is released to drive the round rod 75 and the trigger plate 78 to return to the counterclockwise rotation, the limiting hole 713 will overlap with the fixing block 712 again during the counterclockwise rotation of the trigger plate 78. At this time, the fixing block 712 is engaged with the limiting hole 713 again under the action of the first spring 711, thereby limiting the round rod 75 and the bidirectional screw rod 72.

[0032] like Figure 3 and Figure 4 As shown, the overall shape of the fixing plate 74 is L-shaped, and the inner wall of the fixing plate 74 is fixedly connected with a contact pad 715. When the foam plastic is placed between the two fixing plates 74, the bottom end of the foam plastic is in contact with the inner wall of the fixing plate 74 in the horizontal direction.

[0033] like Figure 2 and Figure 5 As shown, the top of the push rod 79 is curved into a spherical shape, and one side of the trigger plate 78 is curved into an arc shape. When the trigger plate 78 is reset and rotated, the curved side contacts the surface of the fixed block 712, and the fixed block 712 is pressed away from the trigger plate 78 by the arc surface. When the trigger plate 78 continues to rotate counterclockwise to make the fixed block 712 overlap with the limiting hole 713, the fixed block 712 automatically enters the limiting hole 713.

[0034] like Figure 2 As shown, a collection box 714 is provided at the front end of the mounting frame 1. When the foam plastic is cut, when the fixing plate 74 is released from fixing it, the foam plastic will automatically fall into the collection box 714, thereby completing the collection operation of the cut foam plastic.

[0035] like Figure 5 As shown, one end of the fixed block 712 is fixedly connected to the limiting rod 716, and the other end of the limiting rod 716 sequentially passes through the first spring 711 and the mounting block 710. The surface of the limiting rod 716 is slidably connected to the inner wall of the mounting block 710, and when the fixed block 712 is squeezed and moved, the limiting rod 716 is driven to move synchronously.

[0036] When the utility model is in use, when cutting the foam plastic, the round rod 75 is rotated clockwise to drive the trigger plate 78 and the two-way screw rod 72 to rotate synchronously. At this time, the inner wall of the limiting hole 713 will squeeze the fixing block 712 out of the limiting hole 713, and the coil spring 77 will shrink. At the same time, the two sliders 73 will drive the two fixing plates 74 to move and move away from each other. The staff will place the foam plastic between the two fixing plates 74. After the placement is completed, the round rod 75 is released. At this time, the coil spring 77 is released to reset and drive the round rod 75, the trigger plate 78 and the two-way screw rod 72 to rotate counterclockwise. , so that the two fixing plates 74 are close to each other to clamp the foam plastic, and when the trigger plate 78 rotates counterclockwise, the limiting hole 713 will overlap with the fixing block 712 again. At this time, the fixing block 712 is again engaged with the limiting hole 713 under the action of the first spring 711, and the round rod 75 and the bidirectional screw rod 72 are limited. At the same time, the staff can start the motor 6 through the controller to drive the roller 4 to rotate, so that the conveyor belt 5 drives the foam plastic to feed the foam plastic. When the foam plastic passes through the resistance wire 3, the resistance wire 3 can cut the foam plastic.

[0037] After the foam plastic is cut, when the mounting plate 71 gradually rotates from a horizontal state to a vertical state, the trigger plate 78 will contact the push rod 79 and push the trigger plate 78 to drive the round rod 75 and the two-way screw rod 72 to rotate clockwise, thereby moving the two fixed plates 74 away. At this time, the foam plastic will be released and automatically fall into the collection box 714. During the continued rotation of the mounting plate 71, after the trigger plate 78 releases the contact with the push rod 79, the coil spring 77 drives the round rod 75, the trigger plate 78, and the two-way screw rod 72 to automatically reset.

[0038] It should be noted that the motor 6 in the above description is a device with relatively mature application of existing technology. The specific model can be selected according to actual needs. At the same time, the motor 6 can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0039] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
