Description

Technical Field

[0001] The utility model relates to the technical field of weighing, in particular to a plastic particle weighing device. Background Art

[0002] Plastic is a high molecular compound made from monomers through addition or condensation reactions. It is commonly known as plastic or resin. It can freely change its composition and shape. It is composed of synthetic resin and additives such as fillers, stabilizers, lubricants and colorants. Plastic processing requires a series of steps such as cleaning, drying and melting of plastic particles. In order to ensure a certain degree of component ratio, a weighing device is needed to weigh the plastic particles before performing these steps.

[0003] For example, a plastic pellet weighing device disclosed in the patent with announcement number CN219906144U, although this plastic pellet weighing device discharges the plastic pellets inside the silo through the discharge pipe, due to the presence of the partition, the discharge pipe can be divided into two discharge ports on the left and right, so the pellets will be discharged through the two discharge ports on the left and right, and due to the presence of the blocking plate, one of the discharge ports can be blocked, so that the plastic pellets can only be discharged through one discharge port. By taking turns to discharge the pellets through the discharge ports on the left and right ends, it can be ensured that the entire equipment will not be in standby when the worker removes the storage barrel, thereby ensuring continuous discharge and improving efficiency. However, when this plastic pellet weighing device is actually used, when the storage barrel is filled with a certain weight of plastic pellets, the staff is required to pick up the storage barrel, then pour out the plastic pellets in the storage barrel, and then place the storage barrel in the placement slot after the plastic pellets are poured out, and continue to weigh the plastic pellets behind. Since the staff is required to pick up the storage barrel and pour out the plastic pellets in the storage barrel, it is inconvenient for the staff to use it, so it needs to be improved.

[0030] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings and embodiments. It should be understood that the embodiments are merely for explanation of the present invention and are not intended to limit the present invention.

[0031] The following is combined with Figures 1-6 This embodiment is described in further detail.

[0032] like Figure 1 As shown, a plastic particle weighing device in this embodiment includes a workbench 100, a weighing cylinder 110 is provided on the workbench 100, a weighing cavity 111 with an upward opening is provided in the weighing cylinder 110, a slot 112 is provided on one side wall of the weighing cylinder 110 to communicate with the weighing cavity 111, and positioning blocks 120 are provided on both sides of the slot 112, and a first jack 201 and a second jack 202 are provided on the positioning blocks 120 respectively, and a slidable slide is provided between the two positioning blocks 120 130, a sliding cavity 401 is provided in the slide 130, a relative insertion rod 410 is provided in the slide cavity 401, and a driving component is also provided in the slide cavity 401, the driving component is used to drive one end of the insertion rod 410 to insert into the first hole 201 or the second hole 202, so that the slide 130 opens and closes the slot 112, and the positioning block 120 is further provided with a closing component for closing the second hole 202, and the workbench 100 is provided with a weighing component for weighing the symmetrical measuring cylinder 110.

[0033] In this embodiment, the weighing component is an existing electronic scale 160, and the weighing cylinder 110 is placed on the electronic scale 160. When the plastic particles are poured into the weighing cavity 111 from the opening of the weighing cavity 111, the electronic scale 160 can weigh the plastic particles in the weighing cavity 111;

[0034] Among them, when the plastic particles in the weighing cavity 111 are weighed, when the plastic particles in the weighing cavity 111 need to be discharged, the driving component in the sliding cavity 401 slides one end of the insertion rod 410 out of the second insertion hole 202, and then the slide plate 130 is moved upward to open the slot 112, and the driving component drives one end of the insertion rod 410 to be inserted into the first insertion hole 201, so that the position after the slide plate 130 moves upward is positioned. At this time, the slot 112 is in an open state. At this time, the plastic particles in the weighing cavity 111 can be discharged out of the weighing cavity 111 through the slot 112. Compared with the existing device, when this plastic particle weighing device is actually used, the discharge of plastic particles from the weighing cavity 111 is more convenient, and there is no need for manual dumping by the staff, thereby facilitating the actual use of the staff.

[0035] When the plastic particles in the weighing cavity 111 are completely discharged, the driving assembly drives one end of the insertion rod 410 to slide out of the first insertion hole 201, and the driving slide 130 moves downward, and the driving assembly inserts one end of the insertion rod 410 into the second insertion hole 202, so that the slide 130 can close the notch 112. At this time, the weighing cylinder 110 can continue to weigh subsequent plastic particles.

[0036] Among them, the positioning block 120 is fixedly mounted on the weighing cylinder 110, and when one end of the insertion rod 410 is inserted into the first insertion hole 201 or the second insertion hole 202, the position of the sliding plate 130 after movement is positioned;

[0037] When the plastic particles in the weighing cavity 111 are discharged from the notch 112, the plastic particles will flow through the second insertion hole 202. At this time, a small amount of plastic particles may be stuck in the second insertion hole 202, resulting in that after the slide plate 130 moves down, the driving component cannot drive the insertion rod 410 to be inserted into the second insertion hole 202, making the closing effect of the slide plate 130 on the notch 112 poor. When the notch 112 is in an open state, the closing component on the positioning block 120 closes the second insertion hole 202, so that the plastic particles will not be stuck in the second insertion hole 202 when flowing through the second insertion hole 202, thereby preventing the plastic particles from being stuck in the second insertion hole 202, causing the insertion rod 410 on the slide plate 130 to be unable to be inserted into the notch 112, thereby affecting actual use.

[0038] In actual use of this embodiment, an inclined inclined plate 210 is fixedly installed in the weighing cavity 111, and the lower end of the inclined plate 210 is adapted to the notch 112. When the slide plate 130 moves upward to open the notch 112, the plastic particles in the weighing cavity 111 will slide out of the notch 112 along the inclined plate 210, thereby preventing some plastic particles from remaining in the weighing cavity 111, resulting in poor discharge effect of the weighing cylinder 110.

[0039] Among them, a relative card slot 221 is opened on the upper end surface of the slot 112 along its height direction, and a card block 300 is fixedly installed on the side wall of the slide 130 and is locked into the corresponding card slot 221. The cross-sections of the card slot 221 and the card block 300 are both T-shaped. Through the cooperation of the card block 300 and the card slot 221, the slide 130 is slidably installed between the two positioning blocks 120.

[0040] In actual use, a discharge chute 150 is fixedly installed on the weighing cylinder 110. When the plastic particles are discharged from the slot 112, the plastic particles will fall into the discharge chute 150. The plastic particles are guided by the discharge chute 150, making it convenient for the staff to collect the discharged plastic particles.

[0041] like Figure 1-4 As shown, in this embodiment, the other end of the insertion rod 410 is provided with a fixing block 420, and the opposite side walls of the fixing block 420 are provided with a first inclined surface 421;

[0042] The driving assembly includes a driving rod 430 that is arranged in the sliding cavity 401 and can rotate. The driving rod 430 is sleeved with a driving plate 440. The driving plate 440 is provided with a first fixed groove 441 that is opposite to and for the corresponding fixed block 420 to be snapped into. The side walls opposite to the first fixed groove 441 are provided with a second inclined surface 442 that cooperates with the first inclined surface 421. The driving plate 440 is also provided with a second fixed groove 443 that is opposite to the first fixed groove 443. The side walls opposite to the second fixed groove 443 are provided with a third inclined surface 444 that cooperates with the first inclined surface 421. A moving part for driving the two insertion rods 410 to approach each other is also provided in the sliding cavity 401. The driving plate 440 rotates to drive the fixed block 420 to switch between the first fixed groove 441 and the second fixed groove 443, thereby realizing the extension and retraction of the insertion rod 410 in the sliding cavity 401.

[0043] In this embodiment, by setting the fixing block 420, the first inclined surface 421, the driving rod 430, the driving plate 440, the first fixed groove 441, the second inclined surface 442, the second fixed groove 443, the third inclined surface 444 and the moving member, the fixing block 420 is fixedly mounted on the insertion rod 410, the driving rod 430 is rotatably mounted on the side wall of the sliding cavity 401 through the bearing, and the driving plate 440 is fixedly mounted on the driving rod 430. Since the moving member always drives the two insertion rods 410 to approach each other, when the driving rod 430 rotates and drives the driving plate 44 When the first and second fixing slots 441 and 443 are engaged, the first and second fixing slots 443 are engaged with the first and second fixing slots 443. When the first and second fixing slots 443 are engaged, the first and second fixing slots 443 are engaged with the second and second fixing slots 443. When the first and second fixing slots 443 are engaged, the first and second fixing slots 443 are engaged with the second and second fixing slots 443. When the first and second fixing slots 443 are engaged, the first and second fixing slots 443 are engaged with the second and second fixing slots 443. When the first and second fixing slots 443 are engaged, the first and second fixing slots 443 are engaged with the second and second fixing slots 443. When the first and second fixing slots 443 are engaged, the first and second fixing slots 201 and 202 are engaged with the first and second fixing slots 202.

[0044] The first inclined surface 421 and the second inclined surface 442 are arranged so that when the driving plate 440 rotates, the second inclined surface 442 in the first fixing groove 441 presses the first inclined surface 421 on the fixing block 420, so that the fixing block 420 can slide out of the first fixing groove 441 and be locked into the second fixing groove 443.

[0045] When the second locking plate 440 is unlocked, the locking plate 440 is unlocked, and the third locking plate 441 is unlocked.

[0046] The depth of the first fixing groove 441 is greater than that of the second fixing groove 443. When the fixing block 420 is located in the first fixing groove 441, one end of the insertion rod 410 is not located in the first insertion hole 201 or the second insertion hole 202. When the fixing block 420 is located in the second fixing groove 443, one end of the insertion rod 410 is inserted into the first insertion hole 201 or the second insertion hole 202.

[0047] In actual use, one end of the driving rod 430 is extended out of the slide plate 130, and a handle 131 for driving the driving rod 430 to rotate is fixedly installed on the extended end of the driving rod 430. The handle 131 makes it easier to drive the driving rod 430 to rotate, making it more convenient to use.

[0048] like Figure 1-4 As shown, in this embodiment, the moving part includes a support 450 arranged in the sliding cavity 401 and opposite to each other, one end of the insertion rod 410 passes through the corresponding support 450, and the insertion rod 410 located between the support 450 and the fixed block 420 is sleeved with a first spring 460. The first spring 460 is used to push the fixed block 420 away from the support 450, so as to realize the mutual approach of the two insertion rods 410.

[0049] In this embodiment, by setting the support 450 and the first spring 460, the support 450 is fixedly installed in the sliding cavity 401. When the first spring 460 is sleeved on the insertion rod 410, the first spring 460 pushes the fixing block 420 away from the support 450, so that the two insertion rods 410 are close to each other. When the fixing block 420 corresponds to the first fixing groove 441 or the second fixing groove 443, under the action of the first spring 460, the fixing block 420 can be stuck in the first fixing groove 441 or the second fixing groove 443.

[0050] like Figure 1-6 As shown, in this embodiment, a cylinder 140 is provided on the side wall of the positioning block 120, a cavity 601 communicating with the second insertion hole 202 is provided in the cylinder 140, and an intercepting plate 610 is provided at the opening of the cavity 601;

[0051] The closing component includes a circular plate 620 that is arranged in the cavity 601 and can slide. The circular plate 620 is provided with a round rod 621 with one end passing through the intercepting plate 610. A second spring 630 is also provided in the cavity 601. The second spring 630 is used to push the round rod 621 on the circular plate 620 to insert into the second hole 202, so as to realize the closing of the second hole 202 by the round rod 621.

[0052] In this embodiment, by setting the cylinder 140, cavity 601, intercepting plate 610, circular plate 620, round rod 621 and second spring 630, the cylinder 140 is fixedly mounted on the positioning block 120, the round rod 621 is fixedly mounted on the circular plate 620, the intercepting plate 610 is fixedly mounted at the opening of the cavity 601, and the circular plate 620 and the second spring 630 are intercepted in the cavity 601, so as to realize the installation of the circular plate 620 and the second spring 630 in the cavity 601. When the second spring 630 pushes the circular plate 620 to move toward the intercepting plate 610, the movement of the circular plate 620 drives the round rod 621 to be inserted into the second insertion hole 202, so as to realize the closing of the second insertion hole 202 by the round rod 621, thereby preventing some plastic particles from being stuck in the second insertion hole 202 and affecting subsequent use;

[0053] In actual use, when one end of the insertion rod 410 is inserted into the second socket 202, the insertion rod 410 will push the round rod 621 to move, and the round rod 621 moves the driving plate 440 to compress the second spring 630, so that the insertion rod 410 can be inserted into the second socket 202. When one end of the insertion rod 410 slides out of the second socket 202, the second spring 630 is released from compression and pushes the round rod 621 on the circular plate 620 to close the second socket 202 again, thereby preventing plastic particles from getting stuck in the second socket 202 and affecting subsequent use.

[0054] Working principle: first, pour the plastic particles into the weighing cavity 111 from the opening of the weighing cavity 111, and the electronic scale 160 can be used to weigh the plastic particles in the weighing cavity 111. When the plastic particles in the weighing cavity 111 are weighed, it is necessary to discharge the plastic particles in the weighing cavity 111. The driving plate 440 is driven to rotate by the turning hand 131, so that the fixed block 420 is inserted into the first fixed groove 441 from the second fixed groove 443, so that the insertion rod 410 slides out from the second insertion hole 202. Then, the staff moves the slide plate 130 upward, and drives the driving plate 440 to rotate by the turning hand 131, so that the fixed block 420 is inserted into the second fixed groove 443 from the first fixed groove 441, so that the insertion rod 410 is inserted into the first insertion hole 201. At the same time, the position of the slide plate 130 after moving upward is positioned. At this time, the slot 112 In the open state, the plastic particles in the weighing chamber 111 slide into the discharge chute 150 through the inclined plate 210. Then, the staff collects the plastic particles on the discharge chute 150. When the plastic particles in the weighing chamber 111 are completely discharged, the staff drives the driving plate 440 to rotate by turning the hand 131, so that the fixed block 420 is inserted into the first fixed slot 441 from the second fixed slot 443, and the insertion rod 410 slides out from the first insertion hole 201. Finally, the slide plate 130 is moved down and the hand 131 is driven to drive the driving plate 440 to rotate, so that the fixed block 420 is inserted into the second fixed slot 443 from the first fixed slot 441, and one end of the insertion rod 410 is inserted into the second insertion hole 202. The slide plate 130 can close the slot 112, so that the weighing cylinder 110 can continue to weigh the plastic particles behind.
