Description

Technical Field

[0001] This utility model relates to the technical field of dust absorption devices, specifically a dust absorption device for rubber production. Background Technology

[0002] The rubber production process generates a large amount of rubber dust, which not only pollutes the working environment and harms the health of workers, but may also affect the quality of rubber products. Therefore, dust absorption devices are essential in the rubber production process.

[0003] Currently, among the existing technologies, Chinese Patent No. CN212881481U discloses a dust collection device for the production of high-styrene rubber. This device can collect dust in a collection cylinder through the cooperation of a fan, a dust inlet pipe, an exhaust pipe, a slide rail, and a sliding sleeve, and facilitates centralized treatment of the dust inside the collection cylinder. This replaces the trouble of replacing the collection device, making dust treatment more convenient and improving work efficiency. However, in actual use, the dust inlet pipe of this device is fixedly connected. When maintenance is required, the entire connection part often needs to be disassembled, which is complicated and can easily damage the surrounding structure. In view of this, we propose a dust absorption device for rubber production. Utility Model Content

[0004] The main objective of this invention is to provide a dust absorption device for rubber production, which can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model proposes a dust absorption device for rubber production, comprising a base, a collection box fixedly connected above the base, an opening and closing door at the front end of the collection box, a connecting pipe connected to the side wall of the collection box, an exhaust pipe connected to the end of the collection box away from the connecting pipe, a fan and an exhaust hood respectively provided on the exhaust pipe, a dust inlet pipe sleeved on the connecting pipe, and an auxiliary mechanism provided on the side wall of the collection box, the auxiliary mechanism including a first slide groove and a second slide groove, both of which are provided on the side wall of the collection box.

[0006] Preferably, a sliding rod is slidably connected to the slide groove, a round block is fixedly connected to one end of the sliding rod, and a connecting block is fixedly connected to the other end of the sliding rod.

[0007] Preferably, the connecting block one is hinged to a connecting rod, and the end of the connecting rod away from the connecting block one is hinged to a hinge plate, and the sliding groove two is slidably connected to the hinge plate.

[0008] Preferably, a second connecting block is fixedly connected to the side wall of the connecting pipe, and a third connecting block is fixedly connected to the side wall of the dust inlet pipe. Both the second connecting block and the third connecting block have semi-circular grooves on their side walls.

[0009] Preferably, an auxiliary block is fixedly connected above the hinge plate, the auxiliary block has a slot, and a round rod is fixedly connected to the auxiliary block.

[0010] Preferably, a connecting rod is fixedly connected to the side wall of the collection box, and spring piece one and spring piece two are fixedly connected to the lower part of the connecting rod. By pressing spring piece one and spring piece two inward at the same time, the positions of spring piece one and spring piece two are aligned with the slots of the auxiliary block. At this time, pressing the auxiliary block downward can release the position limit of the connecting rod on the auxiliary block. With the cooperation of sliding groove one, sliding groove two, hinge plate and connecting rod, the downward movement of the auxiliary block will drive the sliding rod to slide outward, thereby driving the round block away from the semi-circular slots on connecting block two and connecting block three, thus releasing the position limit between connecting block two and connecting block three. At this time, pulling the dust inlet pipe outward can disassemble and maintain the dust inlet pipe.

[0011] This invention provides a dust absorption device for rubber production. It has the following beneficial effects:

[0012] (1) The dust absorption device for rubber production can simultaneously press the first and second springs inward to make the first and second springs aligned with the slot of the auxiliary block. At this time, pressing the auxiliary block downward will release the position limit of the connecting rod on the auxiliary block. With the cooperation of the first and second slides, the hinge plate and the connecting rod, the auxiliary block moves downward and drives the sliding rod to slide outward, thereby moving the round block away from the semi-circular slots on the second and third connecting blocks, thus releasing the position limit between the second and third connecting blocks. At this time, pulling the dust inlet pipe outward will disassemble and maintain the dust inlet pipe.

[0013] (2) The dust absorption device for rubber production uses spring sheet one and spring sheet two in opposite directions to make the connecting rod securely locked in the slot of the auxiliary block, thereby ensuring the stability of the round block locking. Attached Figure Description

[0023] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-6 This utility model proposes a dust absorption device for rubber production, including a base 1, a collection box 2 fixedly connected above the base 1, an opening and closing door 3 at the front end of the collection box 2, a connecting pipe 4 connected to the side wall of the collection box 2, an exhaust pipe 6 connected to the end of the collection box 2 away from the connecting pipe 4, a fan 7 and an exhaust hood 8 respectively provided on the exhaust pipe 6, a dust inlet pipe 5 sleeved on the connecting pipe 4, and an auxiliary mechanism 9 provided on the side wall of the collection box 2, the auxiliary mechanism 9 including a first slide 91 and a second slide 99, both of which are provided on the side wall of the collection box 2.

[0026] In this embodiment of the utility model, in order to enable the auxiliary mechanism 9 to operate better, specifically, a sliding rod 92 is slidably connected to a sliding groove 91, a round block 93 is fixedly connected to one end of the sliding rod 92, a connecting block 94 is fixedly connected to the other end of the sliding rod 92, a connecting rod 95 is hinged to the connecting block 94, a hinge plate 98 is hinged to the end of the connecting rod 95 away from the connecting block 94, and a sliding groove 99 is slidably connected to the hinge plate 98. A connecting block 96 is fixedly connected to the side wall of the connecting pipe 4, a connecting block 97 is fixedly connected to the side wall of the dust inlet pipe 5, and semi-circular grooves are provided on the side walls of both the connecting block 96 and the connecting block 97. An auxiliary block 910 is fixedly connected above the hinge plate 98, and a slot is provided in the auxiliary block 910. A round rod 914 is fixedly connected to the auxiliary block 910. The round rod 914 can drive the two sets of auxiliary blocks 910 to move together.

[0027] Furthermore, a connecting rod 911 is fixedly connected to the side wall of the collection box 2. A spring piece 912 and a spring piece 913 are fixedly connected below the connecting rod 911. By simultaneously pressing spring pieces 912 and 913 inwards, their positions align with the slots of the auxiliary block 910. At this point, pressing the auxiliary block 910 downwards releases the positional limitation imposed by the connecting rod 911 on the auxiliary block 910. With the cooperation of the sliding groove 91, the sliding groove 99, the hinge plate 98, and the connecting rod 95, the downward movement of the auxiliary block 910 causes the sliding rod 92 to slide outwards. This causes the circular block 93 to move away from the semi-circular grooves on connecting block 2 96 and connecting block 3 97, thereby releasing the positional limitation between connecting block 2 96 and connecting block 3 97. At this time, pulling the dust inlet pipe 5 outward can disassemble and maintain the dust inlet pipe 5. The above-mentioned collection box 2, exhaust pipe 6, fan 7 and exhaust hood 8 are similar in principle to those mentioned in Chinese Patent No. CN212881481U (A material dust collection device for high styrene rubber production) and achieve the same effect. They are existing public technical means in this field and will not be elaborated here.

[0028] In this utility model, when it is necessary to disassemble and maintain the dust inlet pipe 5, the spring piece 1 912 and the spring piece 2 913 should be pressed inward simultaneously so that the spring piece 1 912 and the spring piece 2 913 are aligned with the slot of the auxiliary block 910. At this time, pressing down on the auxiliary block 910 will release the position limit of the connecting rod 911 on the auxiliary block 910. With the cooperation of the sliding groove 1 91, the sliding groove 2 99, the hinge plate 98 and the connecting rod 95, the downward movement of the auxiliary block 910 will drive the sliding rod 92 to slide outward, thereby driving the round block 93 away from the semi-circular groove on the connecting block 2 96 and the connecting block 3 97, thereby releasing the position limit between the connecting block 2 96 and the connecting block 3 97. At this time, pulling the dust inlet pipe 5 outward can disassemble and maintain the dust inlet pipe 5.

[0029] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
