Description

Technical Field

[0001] The utility model belongs to the technical field of PVC plastic production, and in particular relates to a PVC heat stabilizer production and packaging device. Background Art

[0002] Polyvinyl chloride (PVC) is a general-purpose plastic second only to polyethylene (PE) in mass production. It has the advantages of self-extinguishing, flame retardant, wear resistance, high strength, good electrical insulation and chemical stability, and is inexpensive. It is widely used in industry, agriculture, national defense, construction and other fields. However, PVC has a special structure and is processed under high temperature and high shear conditions. It is easy to remove HCL from the molecules and cause polymer degradation, resulting in discoloration of the product and a decrease in the mechanical properties of the product, affecting its service life. Therefore, it is necessary to add a heat stabilizer to increase its stability.

[0003] The prior art discloses a PVC heat stabilizer production and packaging device with a patent announcement number of CN213620485U. The above patent has a storage box when in use. When the stabilizer falls into the packaging bag, as the weight of the stabilizer in the packaging bag increases, the first teeth contact the second teeth, so that the storage box is driven by the active roller to pull the adjacent storage box to move toward the connecting plate. When the first storage box is completely removed from the connecting plate, the second storage box is lifted up by the telescopic rod and the first spring, and the cycle is repeated to achieve that when the weight of the stabilizer in the packaging bag reaches a certain value, the first teeth contact the second teeth, so that the storage box is pulled up by the active roller to move toward the connecting plate. The effect of automatically replacing packaging bags when setting standards reduces the workload of employees and improves packaging efficiency. However, there are still the following shortcomings in actual use: from a practical point of view, the packaging bag needs to be hung on an L-shaped hook. When adding stabilizer to the inside of the packaging bag, the force is uneven, which may cause a part of the packaging bag to be under excessive pressure, thereby increasing the risk of rupture or damage of the packaging bag. Moreover, when the block stabilizer falls into the inside of the packaging bag, due to the effect of gravity, the block heat stabilizer is easily broken into scattered small pieces. Dust may be generated during the dispersion process, which affects the environment.

[0004] Therefore, a PVC heat stabilizer production and packaging device is needed to solve the problems in the prior art that the packaging bag is subjected to uneven force and the block-shaped heat stabilizer is converted into dispersed small pieces during bagging. Utility Model Content

[0007] The bag clamping mechanism consists of a bidirectional threaded rod, a motor, a threaded block, a limit block, a connecting plate, a clamping plate and a fixed plate. The bidirectional threaded rod is rotatably connected to the upper front portion of the storage box, the motor is fixedly connected to the right side of the storage box, and the output end of the motor is connected to the right end of the bidirectional threaded rod.

[0008] It should be noted in the solution that the threaded block is symmetrically threadedly connected to both sides of the bidirectional threaded rod, the limit block is fixedly connected to the top of the threaded block, and the top surface of the storage box is provided with a limit groove adapted to the limit block.

[0010] It should be further explained that the buffer mechanism is composed of a moving block, a protrusion, a telescopic rod, a first spring, a connecting rod, a connecting column, a connecting plate, a fixed cylinder and a second spring. The moving block is symmetrically arranged above the bottom surface of the storage box, the protrusion is fixedly connected to the bottom of the moving block, and a groove matching the protrusion is opened above the bottom surface of the storage box.

[0011] As a preferred implementation, the telescopic rod and the first spring are respectively fixedly connected between the moving block and the inner side surface of the storage box, and the first spring is sleeved on the outside of the telescopic rod.

[0012] As a preferred embodiment, the fixed cylinder is fixedly connected to the bottom surface of the placement plate, the connecting disk is slidably connected to the inside of the fixed cylinder, the second spring is fixedly connected between the connecting disk and the inner top surface of the fixed cylinder, the connecting column is fixedly connected to the bottom surface of the connecting disk, and the connecting column extends out of the fixed cylinder.

[0013] As a preferred embodiment, the upper end of the connecting rod is rotatably connected to the bottom of the connecting column, and the lower end of the connecting rod is rotatably connected to a side of the moving block away from the telescopic rod.

[0014] Compared with the prior art, the PVC heat stabilizer production and packaging device provided by the utility model has at least the following beneficial effects:

[0015] (1) By setting up the bag clamping mechanism, the clamping plate can apply force more evenly while opening the opening of the packaging bag, thereby reducing the risk of the packaging bag being torn or damaged during the process of adding the stabilizer, thereby improving the safety of the device.

[0016] (2) By setting up a buffer mechanism, when adding stabilizer to the packaging bag, the impact and vibration of the stabilizer in the packaging bag due to gravity can be reduced, effectively protecting the stabilizer from damage or deformation, avoiding it from being dropped and crushed, and maintaining the stability of the stabilizer in the packaging bag.

DETAILED DESCRIPTION

[0022] The present invention will be further described below in conjunction with the embodiments.

[0026] Since the limiting block 205 is slidably connected to the inside of the limiting groove 204, the rotation of the threaded block 203 is limited, thereby ensuring the stable linear motion of the threaded block 203.

[0027] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth specifically explaining that the connecting plate 206 is fixedly connected to the upper part of the limit block 205, the clamping plate 207 is fixedly connected to the lower part of the connecting plate 206, and the fixing plate 208 is symmetrically fixedly connected to the left and right sides of the interior of the storage box 1, and the positions of the fixing plate 208 and the clamping plate 207 correspond;

[0028] By clamping the packaging bag 3 by the clamping plate 207 and the fixing plate 208 , force can be applied more evenly, thereby reducing the risk of the packaging bag 3 being torn or damaged during the process of adding the stabilizer.

[0029] According to the above working process, it can be known that: through the bag clamping mechanism 2, when the opening of the packaging bag 3 is opened, the clamping plate 207 can apply force more evenly, reducing the risk of the packaging bag 3 being torn or damaged during the process of adding stabilizer, thereby improving the safety of the device.

[0030] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth specifically explaining that the buffer mechanism 6 is composed of a moving block 601, a protrusion 602, a telescopic rod 603, a first spring 604, a connecting rod 605, a connecting column 606, a connecting plate 607, a fixed cylinder 608 and a second spring 609. The moving block 601 is symmetrically arranged above the bottom surface of the storage box 1, the protrusion 602 is fixedly connected to the bottom of the moving block 601, and a groove matching the protrusion 602 is opened above the bottom surface of the storage box 1.

[0031] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth specifically explaining that the telescopic rod 603 and the first spring 604 are respectively fixedly connected between the moving block 601 and the inner side surface of the storage box 1, the first spring 604 is sleeved on the outside of the telescopic rod 603, the fixed cylinder 608 is fixedly connected to the bottom surface of the placement plate 4, the connecting plate 607 is slidably connected to the inside of the fixed cylinder 608, the second spring 609 is fixedly connected between the connecting plate 607 and the inner top surface of the fixed cylinder 608, the connecting column 606 is fixedly connected to the bottom surface of the connecting plate 607, and the connecting column 606 extends out of the fixed cylinder 608.

[0032] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth to explain in detail that the upper end of the connecting rod 605 is rotatably connected to the bottom of the connecting column 606, and the lower end of the connecting rod 605 is rotatably connected to the side of the moving block 601 away from the telescopic rod 603;

[0033] When the stabilizer is added into the packaging bag 3, it falls on the top of the placement plate 4 due to gravity, and the second spring 609 is squeezed by the downward movement of the placement plate 4. At the same time, the connecting rod 605 drives the moving block 601 to move toward the side wall of the storage box 1, squeezing the telescopic rod 603 and the first spring 604. The elastic force of the first spring 604 and the second spring 609 can absorb part of the impact caused by gravity and reduce the vibration amplitude.

[0034] This solution has the following working process: when in use, first place the packaging bag 3 inside the storage box 1, and the opening of the packaging bag 3 is set between the clamping plate 207 and the fixed plate 208, then start the motor 202 to drive the bidirectional threaded rod 201 to rotate, because the limit block 205 is slidably connected to the inside of the limit groove 204, the rotation of the thread block 203 is limited to ensure the stable linear motion of the thread block 203, and the limit block 205 is driven by the thread block 203 to move in the opposite direction, and the clamping plate 207 is driven to move by the connecting plate 206 until the clamping plate 207 and the fixed plate 208 fix and clamp the packaging bag 3, and the clamping plate 207 can apply force more evenly to reduce the packaging. In order to reduce the risk of bag 3 being torn or damaged during the process of adding stabilizer, the opening of the packaging bag 3 is fixed; then when the stabilizer is added into the interior of the packaging bag 3, it falls on the top of the placement plate 4 due to the effect of gravity, and the second spring 609 is squeezed by the downward movement of the placement plate 4. At the same time, the connecting rod 605 drives the moving block 601 to move toward the side wall of the storage box 1, squeezing the telescopic rod 603 and the first spring 604. The elastic force of the first spring 604 and the second spring 609 can absorb part of the impact caused by gravity, and at the same time reduce the vibration amplitude, protect the stabilizer that falls into the packaging bag 3 from damage, and improve the stability of the stabilizer packaging.

[0035] In summary: by means of the bag clamping mechanism 2, when the opening of the packaging bag 3 is opened, the clamping plate 207 can apply force more evenly, thereby reducing the risk of the packaging bag 3 being torn or damaged during the process of adding the stabilizer, and improving the safety of the device; by means of the buffer mechanism 6, when the stabilizer is added to the packaging bag 3, the impact and vibration of the stabilizer in the packaging bag 3 due to gravity can be reduced, and the stabilizer can be effectively protected from damage or deformation, and prevented from being dropped and shattered, thereby maintaining the stability of the stabilizer in the packaging bag 3.
