Description

Technical Field

[0001] This utility model relates to the field of plastic processing and collection devices, and in particular to a feeding device for plastic processing production. Background Technology

[0002] After processing, plastic granules are usually discharged directly. When feeding from the discharge port, a receiving box is placed below the discharge port to receive the material. However, when the plastic granules fall from the higher discharge port, due to the large height difference, especially when the receiving box is empty, many plastic granules bounce up when they hit the bottom, and some even jump out of the receiving box, causing a large number of plastic granules to be scattered on the surrounding ground, resulting in a large waste of plastic granules.

[0003] Existing methods all involve increasing the height of the receiving box to prevent plastic particles from popping out of the box, but this results in a significant increase in the size of the receiving box, reducing the ease of operation of the receiving box in the future.

[0004] In summary, how to avoid a large number of plastic granules popping out during feeding, while avoiding increasing the size of the receiving box, has become a problem that needs to be solved. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a feeding device for plastic processing and production, thereby avoiding a large number of plastic granules popping out during feeding and without increasing the size of the receiving box.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model provides a feeding device for plastic processing and production, including a discharge mechanism with a discharge port. The feeding device includes a movable support frame that is positioned and installed together with the discharge mechanism. The movable support frame includes two sets of vertical rods, with the two vertical rods in the same set fixedly connected by a horizontal rod, and a set of fixed guide rods fixedly connected between the two horizontal rods.

[0008] The feeding device includes an elastic support assembly movably mounted at a set of fixed guide rods. The elastic support assembly includes multiple perforated steel plates movably sleeved on the side ends of the fixed guide rods. Tension springs are sandwiched between adjacent perforated steel plates and between the perforated steel plates at the side ends and the crossbars. The fixed guide rods are also movably sleeved with short steel pipes. The short steel pipes are in contact with the perforated steel plates near the middle of the fixed crossbars. A connecting rod is rotatably connected to the upper side of the short steel pipes. The elastic support assembly also includes a support plate rotatably connected to the upper ends of all the connecting rods.

[0009] The feeding device also includes a material box, which consists of a box body that is slidably installed between two sets of vertical rods, with the bottom plate of the box body located above the support plate.

[0010] As a preferred technical solution of the present invention: the discharge mechanism has a horizontal locking slot and a first pin hole that penetrates the locking slot vertically. A movable support frame is fixedly welded with an insert plate that mates with the locking slot. The insert plate has a second pin hole that mates with the first pin hole. Pins are installed at the positions of the first pin hole and the second pin hole.

[0011] As a preferred technical solution of the present invention, the bottom inner circumference of the movable support frame is equipped with casters.

[0012] As a preferred technical solution of the present invention: each vertical rod is equipped with multiple guide wheels, and a set of vertical plates of the box body is provided with vertical guide grooves that cooperate with the guide wheels.

[0013] As a preferred technical solution of the present invention, the top of the box is equipped with a lifting handle for moving the box.

[0014] Compared with existing technologies, the beneficial effects of this utility model are:

[0015] This invention features a movable support frame on the discharge port side of the discharge mechanism, with an elastic support component inside the movable support frame. When the hopper is empty, the elastic support component keeps the hopper in a high position, resulting in a lower height difference when the plastic particles are discharged from the discharge port. This prevents the plastic particles from popping out of the hopper. As the number of plastic particles in the hopper increases, although the hopper gradually descends, the height difference at the discharge port does not increase. This also allows workers to easily observe changes in the amount of plastic particles collected in the hopper, preventing plastic particles from overflowing. Attached Figure Description

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the following description is provided in conjunction with the appendix. Figures 1 to 5 The present invention will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0023] Example 1: The overall structure and connection relationship of the device of this utility model are as follows:

[0024] (i) Discharge Mechanism: The discharge mechanism 1 has a discharge port 101 for discharging plastic granules. The discharge mechanism 1 has a horizontal locking slot 102 and a first pin hole 103 that penetrates the locking slot 102 vertically.

[0025] (ii) Mobile support frame: The mobile support frame 2 consists of two sets of vertical rods 201. The two vertical rods 201 in the same set are fixedly connected by a horizontal rod 202 to ensure the structural stability of the entire support frame.

[0026] A set of fixed guide rods 203 are fixedly connected between the two crossbars 202 to provide an installation position for the elastic support assembly 5.

[0027] The bottom inner perimeter of the mobile support frame 2 is equipped with casters 204 to facilitate the movement of the mobile support frame 2 and the material box 3.

[0028] The movable support frame 2 is fixedly welded with a plate 205 that cooperates with the slot 102 of the discharge mechanism 1. The plate 205 has a second pin hole 2051 that cooperates with the first pin hole 103. By installing pins at the positions of the first pin hole 103 and the second pin hole 2051, the movable support frame 2 and the discharge mechanism 1 are positioned and installed.

[0029] (iii) Elastic Support Assembly: The elastic support assembly 5 is movably installed at the position of a set of fixed guide rods 203. It includes multiple perforated steel plates 502 movably sleeved on the side ends of the fixed guide rods 203. Tension springs 501 are clamped between adjacent perforated steel plates 502 and between the perforated steel plates 502 at the side ends and the crossbars 202. The function of the tension springs 501 is to provide elastic support force.

[0030] A short steel pipe 503 is movably sleeved on the fixed guide rod 203, and the short steel pipe 503 is in contact with the perforated steel plate 502 located near the middle of the fixed crossbar 202. A connecting rod 504 is rotatably connected to the upper side of the short steel pipe 503, and a support plate 505 is rotatably connected to the upper end of all connecting rods 504. When the material box 3 is empty or loaded with a small amount of plastic granules, the support plate 505 is in a higher position under the action of the tension spring 501, thereby keeping the material box 3 in a high position as well.

[0031] (iv) Material Box: The material box 3 includes a box body 301, which is slidably mounted between two sets of vertical rods 201. Each vertical rod 201 is equipped with multiple guide wheels 4. A set of vertical plates of the box body 301 has vertical guide grooves 302 that cooperate with the guide wheels 4. The cooperation between the guide wheels 4 and the vertical guide grooves 302 allows the material box 3 to slide smoothly up and down on the vertical rods 201. The bottom plate of the box body 301 is located above the support plate 505. When the amount of plastic particles in the material box 3 increases and the weight increases, the material box 3 will descend along the vertical rods 201 under the action of gravity, while compressing the tension spring 501 in the elastic support assembly 5. The top of the box body 3 is equipped with a lifting handle 303 for carrying the box body 3, making it convenient for workers to carry the material box 3.

[0032] Example 2: The working principle of this utility model device is as follows:

[0033] (i) Initial state: The discharge mechanism 1 is inserted into the slot 102 via the insert plate 205 and fixed with the pin, and is stably connected to the movable support frame 2. At this time, the tension spring 501 in the elastic support assembly 5 is in a naturally extended state, so that the support plate 505 is in a higher position, and the material box 3 is also in a high position under the support of the support plate 505, close to the discharge port 101, and the height difference between the plastic particles falling from the discharge port 101 to the material box 3 is small.

[0034] (ii) Feeding Process: When plastic granules begin to be fed from the discharge port 101, due to the initial high position of the hopper 3 and the small height difference during the fall, the plastic granules will bounce only a limited height upon hitting the bottom and will not pop out of the hopper 3. As the amount of plastic granules in the hopper 3 gradually increases, the weight of the hopper 3 increases. Under the action of gravity, the hopper 3 slowly descends along the vertical rod 201, and the guide wheel 4 rolls within the vertical guide groove 302 to ensure a smooth descent. When the hopper 3 descends, it will compress the support plate 505. The support plate 505 pushes the short steel pipe 503 to move on the fixed guide rod 203 through the connecting rod 504, and compresses the tension spring 501. However, due to the presence of the elastic support component 5, the height difference of the material fed from the discharge port 101 will not increase during the descent of the hopper 3, effectively preventing the plastic granules from popping out of the hopper 3 due to excessive height difference.

[0035] (iii) Material bin handling and replacement: When material bin 3 is full of plastic granules or needs to be moved, the worker can hold the lifting handle 303 to lift material bin 3 to a certain height, so that material bin 3 is detached from the support plate 505. Then, the entire feeding device can be moved to a suitable position using the casters 204, or material bin 3 can be moved to another location for subsequent processing, such as transportation or storage. Afterwards, an empty material bin 3 can be installed to continue the feeding and collection work.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
