Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of plate, more particularly, it relates to a PVC hollow fence plate for animal husbandry, and relates to a production process of the PVC hollow fence plate for animal husbandry. BACKGROUND

[0002] In the production process of the PVC plate, the required molten PVC material is extruded through an extruder by using a mold with a cross-sectional shape, and then the molten PVC material is processed through the mold to obtain a plate-shaped PVC plate. Then, through guiding and cooling fixing, the required PVC plate can be obtained.

[0003] Among the PVC plates, there is a PVC plate with a hollow part, for example, the PVC hollow fence plate for animal husbandry is currently applied more in the scene. The specific structure comprises two parallel baffle plates forming two sides of the PVC plate, and a plurality of equidistant parallel support ribs are integrally formed between the two baffle plates. The support ribs support the two baffle plates to form a hollow state between the baffle plates and have a certain thickness, that is, a hollow PVC fence plate with the required thickness is obtained. The strength performance of the PVC hollow fence plate is mainly supported by the support ribs between the two baffle plates, and the support ribs need to maintain stable shape.

[0004] In the production process of the PVC hollow fence plate, the hollow plate after extrusion is generally supported from the bottom of the lower side, and then cooled and fixed to obtain the required PVC hollow fence plate. Since the size area of the PVC hollow fence plate for animal husbandry is large, the weight of the plate is large, and the PVC hollow fence plate just after extrusion is not completely solidified, the support ribs are subjected to a large downward pressure during the conveying and solidification process, which causes the support ribs to be pressed by the upper baffle plate, and may produce soft collapse and distortion.

DETAILED DESCRIPTION

[0043] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0044] The present embodiment discloses a PVC hollow fence board for animal husbandry, as shown in the figure, which comprises a fence board body 1, the fence board body 1 comprises a baffle one 101, a baffle two 102 and a plurality of support ribs 103, the baffle one 101 and the baffle two 102 are in a state of being separated upward and downward and keeping parallel to each other. Each support rib 103 is fixedly connected between the baffle one 101 and the baffle two 102, plays a role of fixedly supporting the baffle one 101 and the baffle two 102, so as to maintain the whole fence board in a flat state, and each support rib 103 is arranged equidistantly and parallel to each other and has good strength performance. Figures 1-4 As shown in the figure, the fence board body 1 is divided into two parts, an upper half and a lower half, which are respectively extruded by an extruder, and then the upper half and the lower half are connected and fixed by fusion to form a whole fence board. The upper half comprises the baffle one 101 and the support rib 103, and the upper edge of the support rib 103 is integrally formed with the baffle one 101. The lower edge of the support rib 103 is fixedly connected with the baffle two 102.

[0045] Figure 2 As shown in the figure, the fence board body 1 is divided into two parts, an upper half and a lower half, which are respectively extruded by an extruder, and then the upper half and the lower half are connected and fixed by fusion to form a whole fence board. The upper half comprises the baffle one 101 and the support rib 103, and the upper edge of the support rib 103 is integrally formed with the baffle one 101. The lower edge of the support rib 103 is fixedly connected with the baffle two 102.

[0046] ​The baffle two 102 is provided with a plurality of protruding connecting portions 104 corresponding to the supporting ribs 103 on one side of the supporting ribs 103. A connecting groove 105 is formed at the upper position of the connecting portion 104, and the width and position of the connecting groove 105 are matched with the supporting ribs 103. The lower edge of the supporting rib 103 can be embedded into the connecting groove 105 of the connecting portion 104 to realize the connection and limiting of the supporting rib 103 and the baffle two 102, and to play a role of pre-positioning in the heat fusion process.

[0047] As shown in Figure 3 , 4 The inner side wall of the connecting groove 105 is formed with a fixed protruding clamping block 108, and the lower edge of the connecting rib is provided with a clamping groove 107 matched with the clamping block 108. After the supporting rib 103 is embedded into the connecting groove 105, the clamping groove 107 and the clamping block 108 are clamped and limited to realize the firmness compensation between the two.

[0048] The embodiment also discloses a production process of the PVC hollow fence plate for livestock farming, which comprises the following steps:

[0049] Step one: extrusion molding one, the upper half of the fence plate body 1 is extruded by an extruder one, and the upper half includes an integrally formed baffle one 101 and a plurality of supporting ribs 103. The plurality of supporting ribs 103 are arranged in parallel and equidistant state and are in a suspended state on the lower side of the baffle one 101. In the process of extruding and molding the upper half, the supporting device is used for supporting, and the supporting device can be inserted into the interval groove 106 between the supporting ribs 103 to support from the lower side of the baffle one 101.

[0050] During the supporting of the upper half, the baffle one 101 is mainly supported, and a plurality of supporting assemblies one 2 in the supporting device can play a stable supporting effect on the lower side of the baffle one 101. Moreover, the supporting ribs 103 on the lower side of the baffle one 101 are in a suspended state and are not affected by external force, so that the supporting ribs 103 can be kept in a flat state during the shaping process, and the bending and twisting of the supporting ribs 103 can be avoided.

[0051] Step two: extrusion molding two, the lower half of the fence plate body 1 is extruded by an extruder two, and the lower plate part includes a baffle two 102. A plurality of protruding connecting portions 104 are integrally formed on the upper side of the baffle two 102, and the connecting portions 104 correspond to the supporting ribs 103 one by one. The connecting groove 105 is formed at the upper position of the connecting portion 104, and the connecting groove 105 and the supporting rib 103 can form a mutual clamping and limiting state.

[0052] The base melt state baffle two 102 is conveyed to the lower side of the support rib 103 by several guide rollers. When the baffle two 102 is conveyed to the lower side of the support rib 103, the lower side of the baffle two 102 is supported by the hot pressing roller 5, and the support rib 103 and the baffle two 102 are pressed and fused to each other to connect and fix the upper and lower parts of the fence plate body 1. During the fusion process, the baffle two 102 just extruded has a high temperature, and under the pressure action of the hot pressing roller 5, the lower end position of the support rib 103 can be pressed into the connecting groove 105 of the connecting part 104, and the support rib 103 can be heated through heat exchange. The support rib 103 and the connecting part 104 are fused to each other to connect and fix the two, and then the connected fence plate body 1 is cooled and solidified to form a flat fence plate.

[0053] Further, in the extrusion process, the protruding clamping block 108 is integrally formed on the inner side wall position of the connecting groove 105; and the inwardly recessed clamping groove 107 is integrally formed on the lower edge position of the connecting rib, and the clamping groove 107 and the clamping block 108 are matched with each other. When the support rib 103 is embedded in the connecting groove 105, the clamping groove 107 and the clamping block 108 are limited by mutual clamping to keep the upper half and the lower plate part in a stable connected state, and can play a role of pre-fixing the fence plate body 1. After connection and fixation, the clamping groove 107 and the clamping block 108 form a mutual clamping state to increase the strength after connection.

[0054] Further, the hot pressing roller 5 corresponding to the position of the support rib 103 and the connecting part 104 can be actively heated, which can heat during the hot pressing and fusion process and maintain the stability during the hot pressing and fusion, so that the positions of the upper and lower parts can be intermingled to form a stable connection state, further improving the overall strength of the fence plate body 1.

[0055] During the molding process, the support device is used for support, as shown in Figure 5 , 6 The support device includes a support assembly one 2, wherein the support assembly one 2 mainly supports the upper half part after extrusion before the upper half part and the lower half part of the fence plate body 1 are connected.

[0056] The support assembly one 2 comprises a chassis 206 and a plurality of support rails one 201 fixed on the chassis 206, which have a plurality of spacing grooves 106 corresponding to the spacing grooves 106 between the support ribs 103, and the number and position are matched with each other. Specifically, the support rails one 201 are distributed along the length direction of the support ribs 103 and can extend into the spacing grooves 106 to support the upper half of the fence body. The plurality of support rails one 201 are located inside the spacing grooves 106 and can play a flat and stable supporting effect on the lower side of the baffle one 101. During the supporting process, the baffle one 101 mainly plays a supporting role, and the support rib 103 on the lower side of the baffle one 101 is in a suspended state and is not subjected to external force. During the shaping process, the support rib 103 can be kept in a flat state to avoid bending and twisting. After the shaping is completed, the upper half and the lower half are fused by heat pressing. Since the support rib 103 has been solidified at this time, the support rib 103 will not be bent during the heat pressing fusion process, so that the upper and lower parts can be kept in a stable state after fusion and fixation, avoiding twisting and reducing the strength of the plate.

[0057] Specifically, the top of the support rail one 201 is fixedly connected with an upper support frame one 202, and the upper support frame one 202 is rotatably connected with upper support rollers one 203 on both sides. The heights of the two upper support rollers one 203 are consistent, and the overall width is slightly smaller than the width between the two support ribs 103, which plays a rolling supporting role on the lower side of the baffle one 101. By using the rolling supporting mode instead of the sliding supporting mode, the supporting stability of the baffle one 101 can be effectively improved, and the frictional resistance generated during the conveying process can be reduced, and the smoothness of the baffle one 101 conveying can be maintained.

[0058] Further, the support rail one 201 is fixedly connected with a side support frame one 204 on both sides. The number of the side support frame one 204 on each side is two, and a side support roller one 205 is rotatably installed between the two side support frames one 204 on the same side. The side support roller one 205 is vertically arranged and parallel to the support rib 103, and plays a limiting role on the support rib 103 during the conveying process. The distance between the adjacent side support rollers one 205 between the two groups of support assemblies one 2 is greater than the width of the support rib 103, so that the support rib 103 can pass smoothly.

[0059] By limiting the side support roller one 205, on the one hand, the support rib 103 can be limited within a fixed range, avoiding the upper half part from deviating during the conveying process. On the other hand, since the side support roller one 205 is rotatable, even if contact occurs between the support rib 103 and the side support roller one 205, the side support roller one 205 can guide and slide by rolling, thereby reducing the frictional resistance between the support rib 103 and the side support roller one 205, avoiding the support rib 103 from being twisted and deformed due to excessive lateral force during the conveying process, and keeping the support rib 103 in a flat state, thereby improving the overall strength performance of the fence plate after forming.

[0060] As shown in Figure 7 , 8 , the support device further includes a support assembly two 3 connected at the rear end of the support assembly one 2 for supporting after the upper half part and the lower half part of the fence plate body 1 are connected. Specifically, the support assembly two 3 includes a support rail two 301 fixed at the end of the support rail one 201, and the support rail two 301 forms an end extension structure of the support rail one 201 corresponding to the spacing groove 106 between the support rib 103. During the supporting, the spacing groove 106 between the support rail two 301 and the support rib 103 corresponds one by one, and can extend into the inner side of the spacing groove 106 to support the upper half part of the fence body. The lower half part of the fence plate body 1 is fixedly bonded to the lower side of the upper half part, so that after the upper half part is supported, the entire fence plate body 1 can be supported. The entire fence body after bonding and fixing is cooled and solidified by the support of the support assembly two 3.

[0061] As shown in Figure 8 , an upper support frame two 302 is fixedly connected at the top position of the support rail two 301, and upper support rollers two 303 are rotatably installed at the two side positions of the upper support frame two 302. The structure and function of the upper support rollers two 303 are similar to those of the upper support rollers one 203, and the heights of the upper support rollers two 303 are consistent, which can roll and support under the baffle one 101 to form rolling conveying of the baffle one 101, thereby ensuring the stability and smoothness during the conveying process.

[0062] Further, side support frames two 304 are fixedly connected at the two sides of the support rail two 301, and each side has two groups of side support frames two 304 arranged in an upper and lower position. As shown in Figure 8 , side support rollers two 305 are rotatably installed between the two side support frames two 304 at the same side. The side support rollers two 305 are vertical and parallel to the support rib 103, which can limit the support rib 103 during the conveying process. The distance between the adjacent side support rollers two 305 between the two groups of support assemblies two 3 is greater than the width of the support rib 103, which can keep the support rib 103 smooth.

[0063] In the process of fusing the upper half and the lower half of the fence plate body 1, the lower side is supported by the hot pressing roller 5, and the corresponding position on the upper side of the hot pressing roller 5 is provided with a pressing roller. The clamping pressure is formed between the hot pressing roller 5 and the pressing roller, and then the upper half and the lower half of the fence plate body 1 are bonded and fused.

[0064] Further, the side supporting roller two 305 can be arranged in an eccentric structure. The side supporting roller two 305 can adjust the position of the outer periphery of the side supporting roller two 305 by eccentric rotation, and then the spacing between the side supporting roller two 305 can be adjusted. By adjusting the eccentric rotation, the outer periphery of the supporting roller two will produce a clamping effect on the supporting rib 103. After clamping, a certain auxiliary clamping effect can be generated on the supporting rib 103. The clamping pressure generates friction, which can resist a certain fusion clamping pressure. Since the supporting rib 103 is clamped at a low height, most of the upper side of the supporting rib 103 is not subjected to pressure, which can avoid excessive distortion of the supporting rib 103, thereby improving the overall strength and stability of the supporting rib 103 and the fence plate body 1.

[0065] The side supporting roller two 305 is supported by rotating shaft 306, specifically, the side supporting roller two 305 is fixed to the rotating shaft 306 and is in an eccentric state, as shown in Figure 8 、 9 The rotating sleeve 3051 is sleeved on the outer periphery of the supporting roller two, and the rotating sleeve 3051 is supported by the bearing 609 to keep the rotating sleeve 3051 in a stable and smooth rotating state. On the one hand, it can form a lateral pressure on the supporting rib 103, and then the friction force resists the upward and downward pressure; on the other hand, since the rotating guide is formed by the bearing 609, the fence plate body 1 can be kept in a rolling state in the conveying direction, which reduces the conveying resistance and keeps the fence plate body 1 conveying smoothly.

[0066] The eccentric adjustment of the side supporting roller two 305 is realized by the cooperation of the gear 307 and the rack 311. Specifically, the adjustable sliding block 309 is connected to the supporting rail two 301 along the length direction, and the supporting rail two 301 is provided with a sliding groove 308 along the length direction. The sliding block 309 passes through the sliding groove 308 and is slidably connected to the sliding groove 308. The sliding block 309 and the supporting rail two 301 are locked and fixed by the bolt 310, and then the sliding position of the sliding block 309 can be adjusted.

[0067] A rack 311 is fixedly connected to the outside of the slider 309, i.e. the side after rotation; a gear 307 is fixedly connected to the rotating shaft 306, and the gear 307 and the rack 311 are adapted to mesh with each other. By sliding the slider 309, the position of the slider 309 is adjusted, and during the adjustment process, the rack 311 on the outside of the slider 309 drives the gear 307 to rotate, thereby adjusting the eccentric rotation of the side supporting roller two 305 on the rotating shaft 306, and changing the position of the side supporting roller two 305. During the eccentric rotation of the side supporting roller two 305, the spacing of the supporting ribs 103 supported by the side supporting roller two 305 can be adjusted, and the two supporting rollers two can clamp the supporting ribs 103, and by adjusting, a certain spacing between the two is maintained to adapt to different sizes of the supporting ribs 103 width model.

[0068] Further, in order to make the side supporting roller two 305 have a certain flexibility, to more flexibly adapt to the width size of the supporting rib 103. As shown in Figure 10 , the rotating shaft 306 passes through the side supporting roller two 305 and is in a rotating connection structure, two limiting blocks one 3052 are fixedly connected to the outer circumferential position of the rotating shaft 306, and the two limiting blocks one 3052 are in a central symmetric position; two limiting blocks two 3053 are fixedly connected to the end face position of the side supporting roller two 305, and the limiting block one 3052 and the limiting block two 3053 are in a mutually spaced distribution state, and a limiting spring 3054 is elastically pressed between the adjacent limiting block one 3052 and the limiting block two 3053, and the limiting spring 3054 forms an elastic swing state between the rotating shaft 306 and the side supporting roller two 305. Under the action of the limiting spring 3054, the side supporting roller two 305 can be maintained in an intermediate position, and then the side supporting roller two 305 can produce a certain angle of elastic swing interval in the counterclockwise and clockwise directions. During the conveying of the fence plate body 1, the outer circumferential position of the side supporting roller two 305 is always in a state of pressing against the side of the supporting rib 103, thereby maintaining a stable conveying state between the side supporting roller two 305 and the supporting rib 103, and also having a certain pressing force.

[0069] As shown in Figure 8 , 11 , a heat pressing piece 312, i.e. a side supporting frame, is installed at the lower side position of the supporting rail two 301. During the conveying of the fence plate body 1, the heat pressing piece 312 is located at the lower end outside position of the supporting rib 103. The heat pressing piece 312 generates heat after being electrified, and the lower two side positions of the supporting rib 103 are heated and pressed by the heat pressing piece 312, and the lower end edge position can generate a certain melting, thereby better fusing with the baffle two 102 to improve the strength and stability after heat pressing connection.

[0070] As shown in Figure 12As shown, the hot-pressing part 312 comprises a heating block 601 and a hot-pressing sleeve 602. The heating block 601 is an electric heating block 601 with an electric heating wire inside. The hot-pressing sleeve 602 is sleeved on the outer periphery of the heating block 601 and can rotate axially. The heat generated by the heating block 601 can be transmitted outward through the hot-pressing sleeve 602 and then to the lower side of the support rib 103, thereby heating the support rib 103 and facilitating the subsequent fusion of the two. The heating block 601 plays a role in heating compensation, thereby improving the strength and connection stability of the two after fusion.

[0071] The spacing position of the outer periphery of the hot-pressing sleeve 602 is adapted to the connecting part 104 on the upper side of the baffle two 102. The outer periphery of the hot-pressing sleeve 602 is a tapered surface 603 in an inverted conical shape. The tapered surface 603 of the outer periphery of the hot-pressing sleeve 602 will produce an inward extrusion and pushing effect to the two side positions of the connecting part 104, which can press the outer periphery of the two sides of the connecting part 104 and extrude a bevel 109 on the outer side of the connecting part 104. Under the inward extrusion and pushing effect, the hot-pressing sleeve 602 will push the connecting part 104 and the lower side of the support rib 103 to produce a lateral extrusion and pushing effect, which can improve the connection strength and stability between the connecting part 104 and the support rib 103.

[0072] Further, the adjusting shaft 604 is fixedly connected to the upper end position of the heating block 601, and the adjusting hole 605 is formed in the corresponding position of the lower end of the side support frame two 304. The adjusting shaft 604 is adapted to the adjusting hole 605, the upper end of the adjusting shaft 604 is inserted into the adjusting hole 605, and the upper and lower sliding guide is realized through the guide groove 606, and the axial rotation is limited.

[0073] The lower end of the rotating shaft 306 is rotatably supported by the bearing 609, and the screw rod 607 is coaxially connected to the lower end position of the rotating shaft 306. The lower end of the screw rod 607 extends into the screw hole. The upper end of the adjusting shaft 604 is provided with a screw hole matched with the screw rod 607. The screw rod 607 extends into the screw hole and is screwedly connected with the adjusting shaft 604. During the eccentric rotation of the rotating shaft 306, the screw rod 607 is rotated, thereby driving the screw thread transmission with the adjusting shaft 604. During the screw thread transmission, the adjusting block will be slightly adjusted up and down, thereby adjusting the hot-pressing part 312 up and down according to the required position of the connecting part 104. Since the outer periphery of the hot-pressing sleeve 602 is in an inverted conical structure, the pressing state of the two bevels 109 of the connecting part 104 can be changed during the up and down adjustment, so as to adapt to the size and model of the support rib 103 and the connecting part 104 with different thicknesses, and maintain the stable pressure effect of the two during hot-pressing fusion.

[0074] Further, the adjusting shaft 604 is fixedly connected with the heating block 601, and the heating block 601 is in an eccentric structure state on the outer side of the adjusting shaft 604. The heating block 601 is eccentric towards the side close to the support rib 103, so that the heating position of the heating block 601 can be closer to the support rib 103, thereby improving the heating compensation effect on the lower end position of the support rib 103, and being beneficial to the bonding and fixing of the fence plate body 1.

Any technical solution falling within the concept of the present application shall fall within the protection scope of the present application. It should be noted that, for ordinary skilled persons in the art, some improvements and refinements without departing from the principles of the present application shall also be considered as falling within the protection scope of the present application.
